Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machine steel shot recovery structures, in particular to a shot blasting machine steel shot recovery structure. Background Technique

[0002] A steel shot blasting machine is a mechanical device for surface treatment. The steel shot blasting machine mainly uses a high-speed rotating impeller to accelerate and throw steel shots and other projectiles to remove impurities such as scale, rust, and welding slag on the surface of workpieces, and is widely used in industries such as casting, forging, and mechanical manufacturing.

[0003] In the prior art, a shot blasting machine is provided with a recovery mechanism to recover steel shots. The purpose of steel shot recovery is to save the use cost of the shot blasting machine. Most devices use a pneumatic separation method to separate steel shots from small particle impurities. Two guide plates above the air duct are used to make the steel shots fall in front of the air duct in a curtain-like shape. Due to the small width of the curtain, the filtering efficiency is low, and too much steel shot to be pneumatically separated accumulated on the guide plate is also prone to blockage, so the steel shot recovery efficiency is low. To solve the above problems, we propose this shot blasting machine steel shot recovery structure. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a shot blasting machine steel shot recovery structure, which can effectively solve the problems in the background technique.

Two vibrating screens 19 are provided on the plurality of shock absorption assemblies 13. A vibration motor 18 (including a vibration motor 18 body and a cross plate connecting the two vibrating screens 19, and the cross plate is not shown in the figure) is provided on the common side walls of the two vibrating screens 19. Two air blowing pipes 15 (an air inlet pipe is communicated with the air blowing pipe 15, and the air inlet pipe has been shown in Figure 4 the figure) and two suction hoods 16 are provided in the filtering box 10. A discharging pipe 11 is communicated with the lower part of the filtering box 10. A suction pipe 17 is communicated with the suction hood 16.

[0026] A lifting mechanism for lifting steel shots is provided on the discharging pipe 11. The lifting mechanism includes a second lifting pipe 8 provided on the discharging pipe 11. As shown in the figure, a discharging pipe is provided on the second lifting pipe 8. A second motor 7 is provided on the second lifting pipe 8. The output shaft of the second motor 7 is fixedly connected with a second threaded rod 6.

[0027] In the present utility model, one end of the suction pipe 17 away from the suction hood 16 is communicated with a filtering cylinder 12. A fan 21 is provided at the lower end of the filtering cylinder 12, so that the device does not need an external dust suction device, reducing the installation difficulty of the dust suction device.

[0028] In the present utility model, an installation ring is provided in the filtering cylinder 12. A dust removal filter cartridge 20 is provided in the installation ring. The installation of the dust removal filter cartridge 20 is a prior art. As shown in the figure, the filtering cylinder 12 includes two upper and lower parts, and the two parts can be connected by threads or bolts, so that the device has an automatic dust removal mechanism and does not need an external dust removal device, thus enriching the functions of the device.

[0029] In the present utility model, the discharge pipe 9 is a tee pipe, and the two vibrating screens 19 are symmetrically distributed relative to the central axis of the filter box 10.

[0030] In the present utility model, two guide plates are fixedly connected to the inner bottom of the filter box 10, and both of the two guide plates are inclined.

[0031] In the present utility model, the lower end of the guide pipe 2 is provided with an inclined surface, and drainage plates are fixedly connected to both inner walls of the receiving hopper 1, which is convenient for the discharge of steel shots.

[0032] In the present utility model, both the first motor 5 and the second motor 7 are servo motors, so that the lifting speed of the steel shots can be controlled. A sealing cover is provided at the lower end of the first lifting pipe 3, which is convenient for discharging the residual steel shots in the first lifting pipe 3.

[0033] It should be noted that the present utility model is a steel shot recycling structure for a shot blasting machine. The user installs the receiving hopper 1 at the bottom of the shot blasting machine, and the filter box 10, the second lifting pipe 8, etc. are connected to the side wall or the inner wall of the shot blasting machine through connecting rods.

[0034] When the shot blasting machine is in use, the steel shots fall into the receiving hopper 1, and the steel shots enter the first lifting pipe 3 from the guide pipe 2. The first motor 5, the vibrating motor 18, the fan 21 and the external air compressor are started. The output shaft of the first motor 5 drives the first threaded rod 4 to rotate. The steel shots are lifted and enter the filter box 10 through the discharge pipe 9. The vibrating screen 19 screens the steel shots. The large particle impurities remain in the vibrating screen 19, and the steel shots and the small particle impurities flow out of the vibrating screen 19. Under the guidance of the two diversion plates 14, a flow curtain is formed. The air flow blown out by the air blowing pipe 15 blows towards the steel shot flow curtain. The weight of the steel shots is greater than that of the small particle impurities, and they naturally fall and are discharged from the discharge pipe 11, while the impurities are blown into the suction hood 16, and the fan 21 sucks out the impurities. During the process, the automatic recycling and filtering of the steel shots can be realized. By forming two steel shot flow curtains in the filter box 10, the filtering efficiency is faster than that of the traditional single flow curtain.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
