Description

Technical Field

[0001] This utility model relates to the field of polishing cabinet technology, and more specifically, to a polishing cabinet with a dust removal function. Background Technology

[0002] In industrial grinding processes, grinding cabinets are widely used as key standardized equipment in metal processing, wood processing, plastic molding, and other fields. However, traditional grinding cabinets pose significant environmental and occupational health risks during operation. When workpieces on the worktable enter the high-speed grinding stage, the intense friction between the grinding media and the workpiece surface generates dust particles of varying sizes. These dust particles rapidly diffuse as aerosols within the cabinet and gradually dissipate into the workshop environment. From an environmental impact perspective, untreated dust can accumulate on workshop walls, lighting systems, ventilation ducts, and other facilities within a short period, forming a dust layer up to millimeters thick. This not only compromises the cleanliness standards of the production space but may also lead to short circuits in electrical equipment due to dust accumulation. On the floor, the slippery layer formed by the mixture of fine dust and oil significantly increases the risk of slipping and falling for operators. Therefore, we propose a grinding cabinet with a dust removal function to address these issues. Utility Model Content

[0003] The main purpose of this utility model is to provide a grinding cabinet with a dust removal function, which solves the problem that when the workpiece on the table enters the high-speed grinding process, the intense friction between the grinding medium and the workpiece surface will generate dust particles of varying sizes. These dust particles will rapidly diffuse in the cabinet space in the form of aerosols and gradually escape into the workshop environment. From the perspective of environmental impact, untreated dust will accumulate on the surfaces of workshop walls, lighting systems, ventilation ducts and other facilities in a short time, forming a dust layer with a thickness of up to millimeters. This not only violates the cleanliness standards of the production space, but may also cause short circuits in electrical equipment due to dust accumulation. In the ground area, the slippery layer formed by the mixture of fine dust and oil will significantly increase the safety hazard of operators slipping and falling.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A polishing cabinet with a dust removal function includes a cabinet body. A first spray tank is provided on the front surface of the cabinet body. A shelf is installed on the front side of the lower end of the first spray tank. A dust removal mechanism is installed between the first spray tank and the cabinet body. The dust removal mechanism includes a water storage tank located at the lower end of the cabinet body. A guide groove extends through the water storage tank and the first spray tank. A locking groove extends through the lower rear side of the cabinet body, located between the water storage tank and the guide groove. A filter box is locked inside the locking groove. A first recess is provided at the upper rear side of the first spray tank. Guide blocks are installed on the front and rear sides of the upper rear side of the first spray tank, and the guide blocks engage with the first recess. The slots are parallel to each other. The upper inner end of the first groove and the front and rear sides of the upper inner end of the first spray tank are respectively connected by auxiliary pipes. The auxiliary pipes inside the first spray tank are vertically aligned with the guide block. Several water outlet pipes are respectively connected to the lower end of the auxiliary pipes. The rear end of the upper inner surface of the locking slot is provided with a second spray tank. The two sides of the rear end of the cabinet are respectively provided with water storage holes, and the water storage holes are located on both sides of the second spray tank. Several spray heads are respectively connected between the water storage holes and the second spray tank. The upper inner end of the cabinet is provided with a second groove. The upper inner end of the second groove is provided with a suction fan. The lower inner end of the second groove and the second spray tank are connected by an air outlet.

[0006] Preferably, a plurality of drainage grooves are provided through the lower inner surface of the filter box and near the end of the guide groove, a filter layer is installed at the lower inner end of the filter box and the filter layer is located at the upper end of the drainage grooves, and a handle is installed on the rear side of the filter box.

[0007] Preferably, a diversion box is installed on one side of the cabinet, one end of the auxiliary pipe is installed through the inside of the diversion box, a water pump is installed inside the water storage tank, a first connecting pipe is installed through the inside of the water storage tank, the lower end of the first connecting pipe is connected to the water pump, and the upper end of the first connecting pipe is installed through the lower end of the inside of the diversion box.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) In this utility model, a multi-layer water curtain is formed in the first spray tank by a dust removal mechanism. When the suction fan draws the gas in the first spray tank, the external gas carries the dust generated by the grinding of the object on the platform into the first spray tank. The water curtain can adsorb and filter the larger dust particles in the air. The gas after adsorption and filtration enters the second spray tank. The water mist sprayed by several nozzles inside the second spray tank can adsorb and filter the smaller particles in the gas, realizing multi-level purification of dust of different particle sizes. This effectively solves the problem of dust diffusion and dispersion from traditional grinding cabinets into the workshop environment, which leads to dust accumulation in workshop facilities, short circuit risk of electrical equipment, and safety hazards such as slipping and falling of operators. It significantly improves the cleanliness and safety of the production environment.

[0013] (2) In this utility model, the water that falls into the filter box can be filtered through the filter layer and then returned to the water storage tank for reuse, realizing the recycling of water resources, reducing water waste, reducing production costs, and conforming to the concept of environmental protection and energy conservation.

The guide blocks 404 and the first groove 403 are locked inside the first spray tank 3. The three are parallel to each other. The upper part of the first groove 403 and the front and rear sides of the upper part of the first spray tank 3 are respectively connected by auxiliary pipes 405. The auxiliary pipes 405 and the guide block 404 are overlapped in the upper and lower parts of the first spray tank 3. Several water outlet pipes 406 are respectively connected to the lower part of the auxiliary pipes 405. The rear end of the upper surface of the locking groove 423 is provided with a second spray tank 411. The two sides of the rear end of the cabinet 1 are respectively provided with water storage holes 412. The water storage holes 412 are located on both sides of the second spray tank 411. Several spray nozzles 413 are respectively connected between the water storage holes 412 and the second spray tank 411. The upper part of the cabinet 1 is provided with a second groove 421. The upper part of the second groove 421 is provided with a suction fan 422. The lower part of the second groove 421 and the second spray tank 411 are connected by an air outlet 416.

[0025] like Figures 4 to 8As shown, in another embodiment of this utility model, a plurality of drainage grooves 426 are provided through the lower inner surface of the filter box 424 and near the end of the guide groove 401. A filter layer 425 is installed at the lower inner end of the filter box 424, and the filter layer 425 is located at the upper end of the drainage grooves 426. A handle is installed on the rear side of the filter box 424. A diversion box 407 is installed on one side of the cabinet 1. One end of the auxiliary pipe 405 is respectively installed through the inside of the diversion box 407. A water pump 409 is installed inside the water storage tank 402. A first connecting pipe 408 is installed through the inside of the water storage tank 402. The lower end of the first connecting pipe 408 is connected to the water pump 409. The upper end of the first connecting pipe 408 is installed through the lower inner end of the diversion box 407. The cabinet 1 A water guide hole 415 is installed through the rear of the interior. A third connecting pipe 414 is installed between the water guide hole 415 and the water storage hole 412. A second connecting pipe 410 is installed through one end of the water guide hole 415. One end of the second connecting pipe 410 is connected to the first connecting pipe 408. A placement groove 417 is provided at the rear end of the upper surface of the cabinet 1. The placement groove 417 is connected to the air vent 416. A placement rack 418 is installed inside the placement groove 417. A flexible hose 420 is installed through both ends of the placement rack 418. The ends of the flexible hoses 420 that are far apart from each other are installed inside the air vent 416. An adsorption block 419 is installed inside the placement rack 418. A sealing cover is installed at the top of the placement rack 418 via a hinge.

[0026] The user starts the water pump 409, which delivers water through the first connecting pipe 408. The water flows through the first connecting pipe 408 into the distribution box 407, and simultaneously flows along the second connecting pipe 410 into the guide hole 415. The water entering the distribution box 407 then flows into the auxiliary pipe 405. The water flowing into the auxiliary pipe 405 then flows through the outlet pipe 406 into the surface of the first groove 403 and the guide block 404. The water flows along the guide block 404 and the rear surface of the first spray tank 3, creating a water curtain effect. The water flowing along the rear surface of the first spray tank 3 also creates a water curtain effect when passing through the guide chute 401, thus achieving a multi-layer water curtain effect. The water entering the guide hole 415 then flows through the third connecting pipe 414 into the water storage hole 412, allowing the water to be sprayed through the nozzle 413 into the second spray tank 411. The internal structure is a water mist. The user can then start the suction fan 422, which draws the gas inside the first spray tank 3 through the air outlet 416, the second spray tank 411, the locking groove 423, and the guide sloping groove 401. This allows the outside air to carry the dust generated by the grinding on the shelf 2 into the interior of the first spray tank 3 through the front opening of the cabinet 1. At this time, the water curtain adsorbs larger dust particles in the air, such as metal shavings and wood chips, through the principle of gravity settling and inertial collision. Then, the gas filtered by the water curtain carries smaller dust particles and enters the second spray tank 411 at the rear end of the locking groove 423 through the guide sloping groove 401. Then, the water mist sprayed by the water curtain fully contacts the airflow, adsorbing the fine dust. The filtered gas then enters the interior of the shelf 418 through the air outlet 416 and the hose 420, where the adsorption block 419 adsorbs and filters the water vapor in the gas. Finally, the adsorbed and filtered gas is discharged into the second groove 421.

[0027] Dust-laden wastewater in the first spray tank 3 and the second spray tank 411 flows into the filter box 424 through the guide chute 401, allowing the wastewater to be filtered through the filter layer 425 to trap dust and impurities. The filtered clean water flows back to the water storage tank 402 through the drain chute 426. Then, the water pump 409 circulates the water in the water storage tank 402 to the distribution box 407, and redistributes it to the auxiliary pipe 405 and the nozzle 413 through the first connecting pipe 408, the second connecting pipe 410 and the third connecting pipe 414, thus realizing the closed-loop utilization of water resources.

[0028] The working principle of a polishing cabinet with dust removal function:

[0029] In use, the user first starts the water pump 409, which delivers water through the first connecting pipe 408. The water flows through the first connecting pipe 408 into the distribution box 407, and simultaneously flows along the second connecting pipe 410 into the guide hole 415. The water entering the distribution box 407 then flows into the auxiliary pipe 405. The water flowing into the auxiliary pipe 405 then flows through the outlet pipe 406 into the surface of the first groove 403 and the guide block 404. The water flows along the guide block 404 and the rear surface of the first spray tank 3, creating a water curtain effect. The water flowing along the rear surface of the first spray tank 3 also creates a water curtain effect when passing through the guide chute 401, thus achieving a multi-layer water curtain effect. The water entering the guide hole 415 then flows through the third connecting pipe 414 into the water storage hole 412, allowing the water to be sprayed through the nozzle 413 into the second spray tank 403. The interior of the cabinet 11 forms a water mist. The user can then activate the suction fan 422, which draws in the gas inside the first spray tank 3 through the air outlet 416, the second spray tank 411, the locking groove 423, and the guide sloping groove 401. This allows outside air carrying dust generated during sanding on the shelf 2 to enter the first spray tank 3 through the front opening of the cabinet 1. At this point, the water curtain, through gravity settling and inertial collision principles, adsorbs larger dust particles in the air, such as metal shavings and wood chips. Then, the gas filtered by the water curtain carries smaller dust particles and enters the second spray tank 411 at the rear end of the locking groove 423 through the guide chute 401. Then, the water mist sprayed by the gas can fully contact the airflow and adsorb the fine dust. The filtered gas then enters the placement rack 418 through the air outlet 416 and the hose 420, where the adsorption block 419 adsorbs and filters the water vapor in the gas. The adsorbed and filtered gas can then be discharged into the second groove 421.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
