Description

Technical Field

[0001] This invention belongs to the technical field of waste treatment devices, specifically a dust-separating sandblasting waste recycling device. Background Technology

[0002] Sandblasting is a common surface treatment process in the industrial field. It uses high-speed jets of abrasive to impact and cut the surface of a workpiece to remove oxide layers, rust, burrs, etc., thereby improving the surface quality of the workpiece. However, a large amount of waste is generated during the sandblasting process. This waste has a complex composition, mainly consisting of unburned sandblasting material, abrasive particles, and metal dust. The unburned sandblasting material still has value, and if it can be recycled, costs can be significantly reduced. Dust-separating sandblasting waste recycling devices can accurately separate waste, allowing unburned sandblasting material to be recycled and improving resource utilization.

[0003] When existing sandblasting waste treatment equipment is in operation, the filter screen is easily clogged by waste, which obstructs the airflow or material flow within the equipment, affecting the normal processing flow. This necessitates shutdown for cleaning and maintenance, which not only leads to production interruption and reduced processing efficiency but also increases maintenance costs and time. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a dust separation type sandblasting waste recycling device, which effectively solves the problem that when the filter screen of the existing sandblasting waste treatment device is clogged, it is necessary to stop the machine for cleaning and maintenance, which not only leads to production interruption but also reduces processing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust-separating sandblasting waste recycling treatment device, comprising a device body, a support base fixedly installed on one side of the bottom of the device body, a control panel fixedly installed on the front side of the device body, and a discharge valve fixedly installed on the other side of the bottom of the device body, a protective cover fixedly installed on one side of the upper surface of the device body, and an inlet valve fixedly installed on the other side of the upper surface of the device body, a partition fixedly installed in the middle of the bottom of the device body, and a filter screen rotatably installed in the middle of the inside of the device body via a rotating seat; a servo motor fixedly installed at one end inside the protective cover, and a transmission component provided at the output end of the servo motor, the transmission component being connected to the filter screen, and the filter screen being driven to rotate through the transmission component when the servo motor is running, thereby realizing online self-cleaning of the filter screen.

[0006] Preferably, the transmission component adopts a meshing structure of a driving bevel gear and a driven bevel gear, which can realize 90° steering transmission of power. With the cooperation of the bearing seat and the sealed bearing, the stability and sealing of the transmission process are guaranteed, and the internal dust of the device is prevented from leaking into the protective cover and affecting the operation of the motor.

[0007] Preferably, the dust-free brush is made of wear-resistant nylon bristles that fit tightly against the filter screen surface. When the filter screen rotates, it can quickly scrape off the sandblasting particles on the surface. The dust-free brush can be detachably connected via the mounting base, which facilitates later replacement and maintenance and reduces the cost of use.

[0008] Preferably, the air intake hopper of the suction machine is positioned above the filter screen, which can quickly remove sandblasting particles from the device. The sandblasting particles are collected in a storage tank for unified processing. The vent of the storage tank is equipped with a breathable and dustproof membrane to ensure the dust extraction effect while preventing the sandblasting particles from escaping.

[0009] Preferably, the filter screen is a double-layer stainless steel mesh structure, which has good wear resistance and corrosion resistance, is suitable for the harsh treatment environment of sandblasting waste, and extends the service life of the filter screen.

[0010] Preferably, the protective cover is a detachable stainless steel shell, which facilitates the inspection and maintenance of the transmission components. The surface heat dissipation holes can ensure the heat dissipation effect of the servo motor, and the rubber anti-slip pad at the bottom of the support base can effectively improve the stability of the device and prevent displacement caused by vibration during operation.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the filter screen is driven to rotate around the rotating seat by a servo motor and bevel gear transmission assembly, and with the dust-free brush that is in close contact with the filter screen, the filter screen can be self-cleaned online. During the rotation of the filter screen, the sandblasting particles screened on the surface are quickly scraped off by the dust-free brush, which can solve the problem of filter screen clogging without stopping the machine to disassemble, completely avoiding production interruption caused by filter screen cleaning, and greatly improving the continuity of sandblasting waste treatment and overall processing efficiency.

[0012] The air intake hopper of the suction machine is positioned above the filter screen, which can quickly suck out the sandblasting particles in the device. The sandblasting particles are collected into the storage tank. The vent of the storage tank is covered with a breathable and dustproof membrane to ensure smooth airflow while preventing the sandblasting particles from escaping. This achieves efficient separation and collection of sandblasting particles and improves the cleanliness of the workshop environment. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Depend on Figures 1 to 4 The present invention includes a device body 1, which is a stainless steel sealed shell. A support base 2 is welded and fixed to one side of the bottom of the device body 1. A rubber anti-slip pad is adhered to the bottom of the support base 2 to improve the stability of the device placement. A control panel 3 is fixed to the front of the device body 1 by bolts to realize centralized control of the equipment. A discharge valve 4 is fixed to the flange on the other side of the bottom of the device body 1 for discharging the separated qualified sandblasting material.

[0022] A protective cover 6 is bolted to one side of the upper surface of the main body 1. The protective cover 6 is a detachable stainless steel shell with heat dissipation holes on its surface to ensure heat dissipation of the internal motor. An inlet valve 5 is fixed to the flange on the other side of the upper surface of the main body 1, which is the inlet for sandblasting waste. A partition 10 is welded to the middle of the bottom of the main body 1, which divides the inside of the main body 1 into a dust collection area and a sandblasting material recovery area. A filter screen 11 is rotatably installed in the middle of the inside of the main body 1 via a rotating seat 12, which can accurately separate sandblasting material particles and dust.

[0023] A servo motor 13 is fixed to one end of the protective cover 6 by bolts. The output end of the servo motor 13 is equipped with a transmission component. The transmission component includes a shaft 14 welded and fixed to the output end of the servo motor 13. One end of the surface of the shaft 14 is rotatably connected to the inner bottom of the protective cover 6 through a shaft seat 15. A drive bevel gear 16 is welded and fixed to one end of the shaft 14. A driven bevel gear 18 is meshed with the lower part of the surface of the drive bevel gear 16 to achieve a 90° rotation transmission of power.

[0024] A rotating shaft 17 is welded and fixed to the bottom of the driven bevel gear 18. The bottom end of the rotating shaft 17 passes through the partition 10 and is welded and fixed to the center of the filter screen 11. Both ends of the rotating shaft 17 are rotatably connected to the partition 10 through sealed bearings 19 to achieve a sealed rotational fit between the rotating shaft 17 and the partition 10. A dust-free brush 20 is attached to one side of the upper surface of the filter screen 11. The bristles of the dust-free brush 20 are made of wear-resistant nylon. One end of the dust-free brush 20 is detachably connected to the inner wall of one side of the device body 1 through the mounting base 21. The mounting base 21 is fixed to the device body 1 by bolts to facilitate the replacement of the dust-free brush 20.

[0025] A suction machine 7 is welded and fixed to one side of the main body 1 of the device. An air inlet 9 is welded and fixed to the input end of the suction machine 7. The air inlet 9 extends into the interior of the main body 1 of the device and is positioned above the filter screen 11. It can accurately remove sandblasting particles from the device. A storage tank 8 is fixed to the flange at the output end of the suction machine 7. Several vent holes are opened on one side of the storage tank 8. A breathable and dustproof membrane is attached to the vent holes. A control valve is installed on the bottom flange of the storage tank 8 to facilitate the discharge of the collected sandblasting particles.

[0026] Place the device next to a flat sandblasting production line. The rubber anti-slip pad at the bottom of the support base 2 ensures the stability of the device. Start the servo motor 13 and the suction machine 7 through the control panel 3. The servo motor 13 drives the transmission components to rotate, driving the filter screen 11 to rotate at a constant speed around the rotating base 12. The suction machine 7 starts to be in a negative pressure dust suction state.

[0027] Open the inlet valve 5 at the top of the main body 1 of the device to send the sandblasting waste generated by the sandblasting production line into the main body 1 of the device through the inlet valve 5. The waste falls onto the surface of the rotating filter screen 11. The undamaged sandblasting material is trapped on the surface of the filter screen 11 because the particle diameter is larger than the mesh of the filter screen 11. Fine dust passes through the mesh and falls into the dust collection area at the bottom of the main body 1 of the device.

[0028] The servo motor 13 drives the active bevel gear 16 to rotate via the shaft 14. The active bevel gear 16 meshes with the driven bevel gear 18 to rotate, which in turn drives the filter screen 11 to rotate continuously via the rotating shaft 17. The surface of the filter screen 11 rubs tightly against the dust-free brush 20, and the dust-free brush 20 quickly scrapes off the sandblasting particles from the filter screen 11, realizing online self-cleaning of the filter screen, avoiding filter screen clogging, and ensuring the continuity of waste separation.

[0029] The suction machine 7 quickly sucks away the sandblasting particles scraped by the dustless brush 20 through the air inlet hopper 9. The sandblasting particles are transported by the suction machine 7 to the storage tank 8 for collection. The breathable and dustproof membrane of the vent of the storage tank 8 ensures smooth airflow and prevents the sandblasting particles from escaping. The purified air is discharged through the vent, realizing the efficient separation and collection of sandblasting particles.

[0030] After the equipment has been running for a period of time, the control valve at the bottom of the storage tank 8 can be opened to discharge the collected sandblasting particles for unified treatment. If the dustless brush 20 is worn, the bolts of the mounting base 21 can be unscrewed and a new dustless brush 20 can be replaced. If the transmission component malfunctions, the protective cover 6 can be removed for inspection. The entire maintenance process does not require extensive disassembly of the equipment, making it convenient to operate and low in maintenance costs.
