Efficient environmental protection Shot blasting machine automatic production line

six hundred and eighty-eight

With the improvement of environmental protection requirements, the pollution control of production line is more and more strict. Shot blasting cleaning machine It is Shot blasting machine Through the kinetic energy transmission of the motor reducer, the supporting wheel drives the drum of the shot blasting machine, and the drum rotates stably at the speed of 3R / min, so that the parts in the drum of the shot blasting machine can be gently rolled, and the parts can be impacted and scraped by shot blasting at different angles. Thus, not only can the rust, sand and dirt on the surface of the workpiece be removed, but also the inner part of the workpiece can be improved Force, improve the surface quality of the workpiece, achieve the purpose of cleaning and strengthening, and improve the fatigue strength of the workpiece. Almost all steel castings, gray castings, malleable iron castings and ductile iron castings of the shot blasting machine should be shot blasted. This is not only to remove oxide scale and sand sticking on the surface of castings, but also an indispensable preparation process before casting quality inspection. For example, before NDT of large-scale gas turbine casing, shot peening must be carried out strictly to ensure the reliability of flaw detection results. While doing well in construction and production, the discharge must be treated harmlessly to prevent environmental pollution. Almost all steel castings, gray castings, malleable iron castings and ductile iron castings of the shot blasting machine should be shot blasted. This is not only to remove oxide scale and sand sticking on the surface of castings, but also an indispensable preparation process before casting quality inspection. For example, before NDT of large-scale gas turbine casing, shot peening must be carried out strictly to ensure the reliability of flaw detection results. In petrochemical construction, pickling and pickling are commonly used on steel surface Sandblasting However, these two methods have great impact on the environment. The acid washing residue should be neutralized by alkali solution and then tested in the laboratory before discharge. Sand blasting will be broken by the impact of quartz sand and steel plate, which can only be recycled once through fine screen. After being recycled, quartz sand is often powdered, and the dust diffuses with the air, causing serious air pollution. The automatic shot blasting production line is not only superior to the above two items in production efficiency, but also an environmental protection production line. This piece of paper is made by Shot blasting cleaning machine Arranged by the manufacturer

Introduction to production line 1

The lens consists of a feed line system, the delivery system, shot peening, recovered shot, coating, drying, discharge systems, treatment fog, dust treatment, etc., to achieve a complete surface cleaning and corrosion of the workpiece. 120 mg / M dust emission concentration, coating can exchange absorption, sound emission to achieve.

By using 0.8-1.2mm steel ball, the shot can be recycled repeatedly. Due to the small impact of different projectile diameter, all corners of building materials can be cleaned thoroughly. After shot blasting, the material and surface can reach Sa2.5. The automatic spray painting of the material in the spray booth can not only ensure the problem of the treated surface timely and effectively, but also protect the environment from rusting. Moreover, the adhesion and living ability of the paint are strengthened, and the film thickness is uniform.

Shot blasting production line technology can really achieve multi-purpose use, not only can analyze and process the plate, profile and pipe enterprises, but also can process the data of some heads and special-shaped parts of students, which has wide applicability. The schematic diagram of shot blasting production line system is shown in Figure 1.

2. Process and principle of system management

2.1 the whole production line is divided into automatic gear and manual gear. Automatic file can complete all functions of material processing continuously, while manual file can be used by production line function alone. According to different climate conditions and the special requirements of batch work pieces, the automatic file can adjust the computer control program to select combined operation and save resources.

2.2 the loading and unloading system adopts hydraulic lifting and chain drive device for continuous loading and unloading.

2.3 the workpiece transmission system adopts roller table method, and the transmission speed can be adjusted to meet the needs of cleaning work of different materials, workpieces and different degrees of corrosion.

In order to accelerate the development of two shot blasting methods, the speed of shot blasting can reach 2.4 per second.

2.5 the cleaning, purification, recovery and recovery of projectiles have been completed by the separation device, and the pellets are effectively recovered. The recovery rate of the tube for separation and reuse is 100. When the weight of the projectile after reuse is less than the weight recovery rate, it sends a funnel to filter it.

2.6 this kind of high pressure airless spraying technology can be used in the painting treatment system to ensure the effect of paint atomization treatment, so as to make the paint and the workpiece have strong adhesion and uniform film thickness.
