          The working principle and application of the settling chamber of the dust collector of shot blasting machine

          Date of issue:2019/12/12
          The settling chamber of the duster of the shot blasting machine is one of the earliest dust collecting facilities, which is the oldest and simplest dust collecting device. Its working principle is that when the dust gas into a large settling chamber, because the settling chamber's cross-sectional area is much larger than the suction pipe, so the shot-blasting machine dust gas flow rate is greatly reduced, the flow rate can be reduced by 10 ~ 20 times. During the period of dust gas passing through the settling chamber, the larger dust particles in the settling chamber have enough time to settle under the action of gravity, and the purified dust gas is discharged from the other end of the settling chamber. Since the settling chamber is a kind of dust collecting device that USES gravity to make dust settle naturally, it is also called gravity settling chamber or settling chamber for short. The settling chamber of the duster of shot blasting machine has the advantages of simple structure, low cost, small energy consumption, small pressure loss, simple maintenance and management, and can directly deal with high concentration dust-containing gas. However, its huge size and low dust collection efficiency are its fatal shortcomings. In the past, the settling chamber was mainly used in industry to collect dust particles of >40um, or to pre-collect dust in the multi-stage dust collection system. It is not impossible to use the settling chamber for collecting fine dust, but it covers a surprisingly large area. The dust collector system of the shot blasting machine generally takes the settling chamber as the pre-dedusting device of the bag filter, and filters the coarse dust particles in advance to reduce the burden of the bag filter and reduce the wear of dust on the bag.

          Domestic shot blasting machine and foreign technology comparison

          Date of issue:2019/4/8
          Compared with developed countries such as the United States and Europe, there is a certain gap in product service life, processing level, product reliability and control level. The specific performance is as follows: (1) materials and processing equipment: The service life of wear - resistant parts and wear - resistant parts used in shot blasting chamber and shot blasting chamber is far from that of China. (2) design level: At present, the independent development ability of designers in China is still not enough, and most enterprises are still in the stage of imitation, while the test conditions and design conditions are not suitable and ideal. (3) control level: There is still a certain gap between China's intelligent control, automation level and automatic monitoring technology and foreign advanced level. With the continuous development of technology and practical requirements for the workpiece surface quality requirements continue to improve, the workpiece surface cleaning has become an indispensable means of processing in the production activities, so it requires cleaning equipment and technology to further improve and develop. Since its appearance, shot blasting technology has been widely used because of its high productivity, good cleaning effect and low energy consumption. Shot blasting machinery has developed from a relatively single type of machinery into a field, from a single production process to the development of an indispensable part of the whole production process. After decades of development, shot blasting machine from the traditional single type to the present multi-type development, from horizontal movement to multiple directions. Shot blasting machine is slowly extending to each industry, to each industry production and technology has brought great convenience. Over the years, the technology and equipment of shot blasting have been gradually perfected, and the performance has been improved constantly. The application scope has also expanded from surface cleaning in casting industry to different industries such as road cleaning, mechanical processing, weapon manufacturing, metallurgical mines, vehicles and ships.

          Beijing catenary through the type of shot blasting machine sales

          Date of issue:2019/4/8
          Facing the top city like Beijing, there is still the same demand and purchase for the shot blasting machine. Yancheng huaqing machinery co., ltd. is a shot-blasting equipment research and development and production enterprises, and Beijing customers have an inseparable relationship. With the history of hundreds of years since human beings entered the industrial age, the industrial level has been constantly improved, which also makes the production technology and standards in the industrial field continuously improved. As the concept of environmental protection is more and more accepted by people, some traditional pickling and derusting processes that cause environmental pollution will eventually drop out of the stage, followed by the rise of such environmentally friendly casting equipment as through shot blasting machine and catch-through shot blasting machine. The catenary through shot blasting machine sold to Beijing is mainly used for the shot blasting processing of large quantities of workpiece. The shot blasting machine is a kind of single-stroke catch-chain continuous shot blasting cleaning equipment, which has the functions of static loading and unloading of workpiece, automatic rapid transportation and positioning, rotating shot blasting cleaning of workpiece and so on. Because the catenary through the shot blasting machine usually adopts the conventional electrical control, and the workpiece conveying track stepless speed regulation this characteristic. So it is more suitable for large quantities, cast steel, cast iron, and welding parts of the overall shot blasting cleaning, and can be used in various forms of hanging workpiece. The Beijing customer with my company through type shot blasting machine to blast cleaning of artifacts, not only can get rid of rust on the surface of the component, clean up the welding slag on the material, also can eliminate the welding stress of the workpiece, improving the fatigue strength of the component, thus increase the film adhesion when painting, components and eventually to improve the quality of the whole processing of the surface of the component and the inner purpose. Just because of this, catenary through shot blasting machine is widely used in metallurgy, petroleum, chemical industry, machinery and other industries. With the increasing punishment and management of industrial enterprises and production methods that seriously harm the environmental quality, some original production technologies and backward equipment are gradually losing their market and status in the past, and the new type of shot blasting and derusting equipment such as catch-and-chain shot blasting machine will dominate the future foundry industry.

          Shot blasting machine for the major enterprises to bring economic benefits

          Date of issue:2019/4/8
          In today's society, protecting the environment has become an important part of a harmonious society, and all production methods that damage the environment will be eliminated by this social era. With the development of this situation, the pickling and cleaning of metal structure, machine tool bed, steel products, net frame, engineering machinery and bridge manufacturing industry will eventually be replaced by the new shot blasting machine! What kind of shot blasting derusting equipment is it? What are the advantages of this shot blasting machine to achieve such a high popularity? According to the investigation, first of all, through the shot blasting machine can work continuously, easy to operate and environmental protection and energy saving characteristics. Through type shot blasting mechanism in a straight through the way of various steel plate, steel, steel, steel, steel tube and steel in addition to scale, cleaning and pretreatment, and use through type shot blasting machine is just the required processing of steel products such as loading machine, gently press the start button, after a short cycle, shot blasting machine system will deal with good material, so as to complete the whole cleaning process, remove all the dust and the residual pill. Because of this, it can be called the environmental protection of the industrial - shot blasting machine. Through the type of shot blasting machine is also divided into roller through the type of shot blasting machine and catenary through the type of shot blasting machine. Both from the big aspects of the ten thousand changes from the same, belong to the category of through the shot blasting machine, also have through the general characteristics of the shot blasting machine. But from the details, the two from the internal structure, operating principle and so on have a lot of differences.
