The components of roller conveyor shot blasting machine

1. Blasting chamber-The blasting chamber is a large-capacity plate type box-shaped welding structure. The inner wall of the chamber is lined with a ZGMn13 wear-resistant protective plate. The blasting operation is carried out in a sealed cavity. To achieve the purpose of improving the surface and internal quality of the workpiece, and ultimately to improve the corrosion resistance of mechanical products and metal profiles, improve the fatigue resistance of steel, and extend its service life;

2. Conveyor roller conveyor-divided into blasting chamber conveyor roller and loading and unloading section conveyor roller conveyor. PLC control, host computer dynamic simulation monitoring. The high chromium wear-resistant jacket and limit ring are used for the indoor rollerway jacket. The high chromium wear-resistant jacket is used to protect the roller table and withstand the impact of projectiles. The limit ring can make the workpiece run at a predetermined position to prevent deviation and cause accidents.

3. Bucket elevator-mainly composed of upper and lower transmission, cylinder, belt, hopper, etc. The upper and lower belt pulleys of the same diameter of the bucket elevator are welded into a polygonal structure with ribs, wheel plates and hubs to enhance friction, avoid slipping, and extend the service life of the belt. The bucket elevator casing is bent into shape, and the cover on the middle casing of the bucket elevator is opened to repair and replace the hopper and the lap belt. Open the cover on the lower shell of the bucket elevator to eliminate the blockage of the bottom projectile. Adjust the bolts on both sides of the upper shell of the bucket elevator to drive the pull plate to move up and down to maintain the tightness of the bucket elevator belt. The upper and lower pulleys adopt square outer spherical ball bearings, which can be adjusted automatically when subjected to vibration and impact, and have good sealing performance.

4. Separator-the screw conveyor is mainly composed of a geared motor, a screw shaft, and a screw body shell. The outer spherical ball bearing with square seat is adopted, which can automatically adjust when subjected to vibration and impact, and has good sealing performance. In the painting industry, shot blasting machines are used for pretreatment of the surface of the workpiece, such as radiators, gas cylinders, steel drums, containers, barrels, tubes, drums, etc., to ensure the perfect adhesion of the paint on the workpiece.

5. Abrasive guide pipeline-This pill conveying pipeline has a double control function. Each pipe is equipped with a gate to cut off the projectile from the separator to facilitate maintenance of the respective blast turbines; the opening size of the gate can be Adjust the abrasive flow rate, and can also arbitrarily combine the number of opening and closing gates according to the specifications of the cleaning workpiece to save energy, reduce the wear and tear on the machine, and ensure that the production needs are met.

6. Wheel blast turbine-the single-disc blast turbine has become the perfect high-level shot blasting turbine in China today. It is mainly composed of rotating mechanism, impeller, cover, control cage, abrasive distributor, guard plate, etc. The impeller is made of Cr40 material and forged, and the blades, control cage, abrasive distributor and guard plate are all made of high chromium.

7. Blowing device-This device uses a high-pressure fan, and multiple sets of elastic blowing nozzles with different angles are arranged in the auxiliary chamber of the chamber to blow and clean the steel shots remaining on the surface of the workpiece.

8. Inlet and outlet seals—the inlet and out seals of the workpiece are all made of rubber spring steel plate. In order to prevent the steel shots from splashing out of the blasting room during shot blasting, multiple strengthened seals are provided at the entry and exit of the workpiece, which are characterized by elasticity. Strong, long life, excellent sealing effect.

9. Dust collector system-cartridge type dust collector: The dust collector system is mainly composed of a cartridge filter, a fan, and a dust collector pipeline. Using Donaldson technology, the dust removal efficiency can reach 99.5%. If there are too many shots at the bottom of the elevator, shut down in order and remove the shots.

10. Electrical control-The electrical control system uses conventional control to control the entire machine. It adopts high-quality electrical components produced and has the advantages of high reliability and convenient maintenance. The main circuit is implemented by small circuit breakers and thermal relays to realize the control of each motor. Short circuit, phase loss, and overload protection. It is equipped with multiple emergency stop switches to facilitate emergency shutdown and prevent the expansion of accidents. There are safety protection switches on each access door of the cleaning room and the cleaning room. When any access door is opened, the shot blasting device cannot be started.
