TECHNICAL FIELD

[0001] The utility model relates to work piece processing dust falling technology field, specifically a work piece processing dust falling device. BACKGROUND

[0002] Workpiece refers to the part in the machining process, which needs to go through various process operations in the machining process. A large amount of dust will be generated in the workpiece machining process, which not only pollutes the environment, but also harms the health of workers. Therefore, dust falling treatment is needed to effectively reduce the dust content in the air, create a healthier and cleaner working environment for workers, and reduce the risk of occupational diseases.

[0003] A patent with publication number CN218309906U discloses a casting part polishing dust falling device, which includes a bottom plate, two side top parts of the bottom plate are fixedly connected with stand columns, the top part of the stand column is fixedly connected with a support frame, the middle bottom part of the support frame is fixedly connected with a guide rod, the bottom part of the guide rod is fixedly connected with a polisher. When in use, the protective mechanism is set. When the product needs to be polished, the dust cover is lowered by the winch, and the polisher is placed inside the dust cover to reduce dust spatter during polishing and improve protection for workers. The dust falling mechanism is set to facilitate the collection and treatment of dust generated during polishing, reduce environmental pollution, and meet the use requirements.

[0004] The above-mentioned casting part polishing dust falling device only uses the dust collection mechanism to reduce dust when processing workpieces. If the sealing of the dust collection mechanism is insufficient or the operation is improper, it may cause dust raising, which not only reduces the dust falling effect, but also may cause secondary pollution to the working environment. Therefore, a workpiece processing dust falling device is proposed to solve the above-mentioned problems. Utility model content

The atomized water comes into contact with the dust in the dust collection box, wetting the dust and causing it to settle onto the filter screen, preventing dust from being stirred up and further improving the dust suppression effect. Particulate impurities in the wastewater are intercepted and accumulated on the filter screen, while the impurity-free water flows through the filter holes into the collection tank, providing a water source for subsequent spray dust suppression operations and realizing the recycling of water resources. By combining dust collection and spray dust suppression, a more efficient and comprehensive dust suppression effect can be achieved.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0021] Please refer to Figures 1-5As shown, a dust suppression device for workpiece processing includes a support platform 1, a placement plate 2 mounted on the support platform 1, a groove 3 formed on the placement plate 2, two sliders disposed within the groove 3, clamping plates 4 fixedly connected to the top of each slider, and dust suction hoods 7 fixedly connected to the top sides of each clamping plate 4. A dust collection box 8 is fixedly connected to the bottom side of the support platform 1, and dust suction pipes 10 are connected between the two side walls of the dust collection box 8 and the corresponding dust suction hoods 7. A water collection pool 9 is connected to the bottom side of the dust collection box 8, and a negative pressure pump 11 is mounted on the side wall of the dust collection box 8. An air extraction pipe 12 is connected to the input port of the negative pressure pump 11, and an air extraction pipe 12 is connected to the output port of the negative pressure pump 11. An arc-shaped filter 14 is installed on one inner wall of the exhaust pipe 13 and the dust collection box 8, surrounding the port of the exhaust pipe 12. A filter plate 15 is installed inside the bottom port of the dust collection box 8. Two hollow tubes 16 are installed inside the dust collection box 8, each equipped with an atomizing nozzle 17. The two hollow tubes 16 are connected by a U-shaped tube 18. A water pump 19 is installed on the outer wall of the water collection tank 9. The inlet of the water pump 19 is connected to a water suction pipe, which is located inside the water collection tank 9. The outlet of the water pump 19 is connected to a delivery pipe 20, and the other end of the delivery pipe 20... Connected to the U-shaped tube 18; during the workpiece grinding process, a large amount of dust is generated. In order to improve the dust reduction effect, when the workpiece is subjected to dust reduction treatment, the negative pressure pump 11 is started, so that the gas in the dust collection box 8 is extracted through the suction pipe 12 and discharged through the exhaust pipe 13, so that the inside of the dust collection box 8 is in a negative pressure state. This allows the dust and debris generated during the grinding process to be sucked into the dust collection box 8 through the cooperation of the dust suction hood 7 and the dust suction pipe 10, thereby effectively cleaning and collecting the dust and debris generated during the grinding process, achieving the purpose of dust reduction. At the same time, the water pump 19 is started, so that the water in the water collection pool 9 is pumped through the suction pipe 11. Water is drawn out through the pipe and flows into the U-shaped pipe 18 through the delivery pipe 20, then into the hollow pipe 16, and finally sprayed out through the atomizing nozzle 17. The atomized water comes into contact with the dust in the dust collection box 8, wetting the dust and causing it to settle onto the filter screen 15, thus preventing dust from being stirred up and further improving the dust suppression effect. Particulate impurities in the wastewater are intercepted and accumulated on the filter screen 15, while water without impurities flows into the water collection pool 9 through the filter holes, facilitating the supply of water for subsequent spray dust suppression operations and realizing the recycling of water resources. By combining dust collection and spray dust suppression, a more efficient and comprehensive dust suppression effect can be achieved.

[0022] A discharge port is provided on one side wall of the dust collection box 8. Limiting slide rails 21 are fixed to both sides of the discharge port. The two limiting slide rails 21 are slidably fitted with sealing cover plates 22. Two through slots 23 are provided on the support platform 1, and the dust collection pipe 10 is installed through the through slots 23. When using the device, the discharge port can be opened or closed as needed by the cooperation of the limiting slide rails 21 and the sealing cover plates 22, so as to facilitate the removal of impurities collected in the dust collection box 8.

[0023] Please refer to Figure 3 As shown in the figure, the chute 3 is rotatably mounted with a bidirectional screw rod 5, and the bidirectional screw rod 5 penetrates the sliding block. The outside wall of the placement plate 2 is provided with a motor 6, and the output end of the motor 6 is connected with one end of the bidirectional screw rod 5. When polishing the workpiece, in order to avoid the workpiece from deviating during polishing, the workpiece needs to be clamped and fixed. First, the workpiece to be polished is placed on the placement plate 2, and the motor 6 is started to make the bidirectional screw rod 5 rotate, and then the two sliding blocks drive the two clamping plates 4 to move close to each other, so that the workpiece can be effectively clamped and fixed, avoiding the phenomenon of workpiece deviation during polishing.

[0024] Please refer to Figure 1 As shown in the figure, the top side of the support table 1 is fixedly connected with a fixing frame 24, the fixing frame 24 is provided with a pneumatic cylinder 25, the acting end of the pneumatic cylinder 25 is assembled with a pneumatic rod 26, the bottom end of the pneumatic rod 26 is fixedly connected with a fixed frame 27, the fixed frame 27 is provided with an electric motor 28, and the output end of the electric motor 28 is provided with a polishing disc 29.

[0025] Working principle: Since the above-mentioned casting polishing dust falling device, when the workpiece is treated by dust falling, only the dust falling mode is realized by the dust suction mechanism. During the dust suction process, if the sealing performance of the dust suction mechanism is insufficient or the operation is improper, dust raising phenomenon may occur, which not only reduces the dust falling effect, but also may cause secondary pollution to the working environment. Therefore, a workpiece machining dust falling device is proposed to solve the above-mentioned problems. A large amount of dust is generated during the workpiece polishing process. In order to improve the dust falling effect, when the workpiece is treated by dust falling, the negative pressure pump 11 is started to make the gas in the dust collecting box 8 extracted through the air extraction pipe 12 and discharged through the exhaust pipe 13, so that the inside of the dust collecting box 8 is in a negative pressure state, so that the dust and debris generated during polishing can be sucked into the dust collecting box 8 through the cooperation of the dust suction cover 7 and the dust suction pipeline 10, thereby effectively cleaning and collecting the dust and debris generated during polishing, achieving the purpose of dust falling, and at the same time, the water pump 19 is started to make the water in the water collecting tank 9 extracted through the water extraction pipe and flow into the U-shaped pipe 18 through the conveying pipeline 20, then flow into the hollow pipe 16, and finally be sprayed out through the atomizing nozzle 17. The atomized water contacts the dust in the dust collecting box 8, making the dust wet and settling on the filter screen 15, avoiding the dust raising phenomenon, further improving the dust falling effect, and the particulate impurities in the sewage are intercepted and accumulated on the filter screen 15. The water without impurities flows into the water collecting tank 9 through the filter hole, which is convenient for providing water source for subsequent spray dust falling operation, realizing the recycling of water resources, and realizing more efficient and more comprehensive dust falling effect through the combination of dust suction and spray dust falling.
