Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology, and in particular to a dust collection cabinet. Background Technology

[0002] Existing machining processes, such as polishing and grinding, generate significant dust pollution during workpiece surface treatments. Without proper dust removal equipment, this dust not only severely pollutes the working environment and affects the health of workers, but also poses a significant safety hazard due to dust accumulation and the potential for explosions. While existing polishing and grinding machines may employ fans to collect dust, this process simply involves the fan drawing the dust into a dust collection box. Failure to clean the dust collection box promptly can result in sparks igniting the entire box or even the entire equipment, posing a considerable safety risk.

[0003] To address the aforementioned issues, some existing technologies have developed water curtain dust collection devices that utilize fans to extract grinding dust and mix it with a water curtain to achieve dust collection. However, these water curtain dust collection devices typically discharge the generated wastewater directly. Over time, this not only wastes a significant amount of water resources but also increases the production costs for enterprises. Therefore, there is an urgent need to provide a dust collection cabinet. Utility Model Content

[0019] Example To address the issue of existing dust collection devices wasting water resources and thus increasing production costs, see Appendix. Figures 1 to 4 As shown, this application discloses a dust collection cabinet, including a water tank 10, a cabinet body 20, and a spraying mechanism 30; Water tank 10 is arranged along the first direction; The cabinet 20 is detachably mounted on one side of the water tank 10 and communicates with the water tank 10. In other words, the lower part of the cabinet 20 is open and the upper part of the water tank 10 is open. An air inlet duct 21 for dust extraction is provided on one side of the cabinet 20, and an exhaust duct 22 and an exhaust unit 23 connected to the exhaust duct 22 for exhaust are provided on the top of the cabinet 20. The exhaust unit 23 includes a fan 231, which is located on the top of the cabinet 20 and connected to the exhaust duct 22 through an air duct 232. The spraying mechanism 30 includes a circulating water pumping unit 31 and a spraying unit 32. The spraying unit 32 is installed on the inner top wall of the cabinet 20 near the air inlet duct 21 to form a water curtain. The circulating water pumping unit 31 is installed on the water tank 10 and connects the water tank 10 to the spraying unit 32 to circulate and pump water from the water tank 10 to the spraying unit 32. The spraying unit 32 includes a spray pipe 321 and several water curtain nozzles 322. The spray pipe 321 is installed on the inner top wall of the cabinet 20 near the air inlet duct 21, and the water curtain nozzles 322... 2 are arranged and installed below the spray pipe 321. The circulating water pumping unit 31 includes a circulating pump 311 and a filter 312. Both the circulating pump 311 and the filter 312 are located at the first end of the water tank 10. The inlet end of the filter 312 is connected to the drain pipe 14 at the first end of the water tank 10 through the first water pipe 313. The outlet end of the filter 312 is connected to the pumping end of the circulating pump 311 through the second water pipe 314. The circulating pump 311 is connected to the spray pipe 321 through the cabinet 20 through the third water pipe 315. In practice, the fan 231 is started and runs. The fan 231 draws air from the exhaust duct 22. At this time, the dust generated by grinding will enter the cabinet 20 from the air inlet duct 21. During this process, the circulating pump 311 draws water from the water tank 10 for filtration and then delivers it to the spray pipe 321. It is then sprayed out through several water curtain nozzles 322 to form a water curtain. When the dust and the water curtain intersect, wastewater will be generated and enter the water tank 10, thereby achieving the collection of dust.

[0020] Two points need to be explained here. First, before the equipment is put into operation, the water tank 10 needs to be filled with water so that the circulating pump 311 can have water available. Second, the purpose of the first water pipe 313, the second water pipe 314, and the third water pipe 315 is to carry water, which will not be elaborated here.

[0021] In one specific embodiment, steps 11 are formed on the upper sides of the water tank 10 in the second direction, and horizontal mounting plates 201 are formed on the bottom sides of the cabinet 20 in the second direction by bending outward. The two mounting plates 201 at the bottom of the cabinet 20 are respectively locked to the two steps 11 by bolts (not shown in this application). Based on this structure, the cabinet 20 and the water tank 10 can be quickly installed, which is beneficial for operators to clean the water tank 10 part below the cabinet 20.

[0022] In a preferred embodiment, to achieve initial filtration of wastewater during the flow of wastewater in the water tank 10, this application arranges several screen plates 12 with gradually increasing height along the first direction inside the water tank 10, and the screen plates 12 form several cavities 13 in the water tank 10. Each cavity 13 has a drain pipe 14 at its bottom, and a manual valve 15 is installed at the connection between the drain pipe 14 and the water tank 10. In specific implementation, the wastewater generated after the dust and water curtain mix will fall directly into the first direction of the water tank 10. As the circulating pump 311 continuously pumps water, the wastewater in each cavity 13 will flow into the next cavity 13 after it is full, and the particulate matter in the wastewater will sink to the bottom of the cavity 13 for recycling. In this way, the water becomes cleaner as it flows, thereby achieving the purpose of filtration. When the equipment is not in use, the operator can open the corresponding manual valve 15 to discharge the wastewater in the cavity 13.

[0023] It should be noted that the manual valve 15 at the first direction end of the water tank 10 must always be open so that the circulating pump 311 can continuously pump water.

[0024] Based on the above solution, this application also attaches a dustproof plate 40 above the two steps 11 on the part detached from the cabinet 20 by bolts (not shown in this application), so that other dust in the workshop will not fall into the water tank 10, thereby ensuring the quality of the water resources in the water tank 10.

[0025] In one specific embodiment, an isolation plate 50 is provided below the inner top wall of the cabinet 20 to separate the spray unit 32 from the exhaust duct. An L-shaped guide plate 60 is provided below the discharge duct 22 on the inner top wall of the cabinet 20. An inclined guide plate 70, which is offset from the L-shaped guide plate 60, is provided on the side of the isolation plate 50 near the exhaust duct. The isolation plate 50 can prevent the fan 231 from directly sucking away the water sprayed from the water curtain nozzle 322. In addition, the design of the L-shaped guide plate 60 and the inclined guide plate 70 can reduce the amount of water vapor sucked away by the fan 231, thus ensuring the dryness of the air discharged by the fan 231.

[0026] In one specific embodiment, the filter 312 of this application is provided with a removable cover 3121 on top. Several honeycomb filter plates 3122 are arranged inside the filter 312 along the first direction. When the circulation pump 311 is working, the water at the end of the water tank 10 in the first direction will enter the filter 312 and be filtered by the several honeycomb filter plates 3122 before being discharged. In this way, the water sprayed by the water curtain nozzle 322 can be kept relatively clean. Based on this structure, the operator can easily replace the several filter plates inside the filter 312, which has strong practicality.

[0027] Furthermore, it should be emphasized that the first direction involved in this application is the horizontal direction, and the second direction is the vertical direction.
