Description

Technical Field

[0001] This utility model relates to the field of equipment dust prevention and cleaning technology, and in particular to a dust prevention and cleaning device applied to high-purity water equipment. Background Technology

[0002] High-purity water equipment is widely used in industrial production, laboratory analysis, and electronics manufacturing to produce high-purity water to meet the demands of precision processes. This type of equipment typically consists of a multi-stage filtration system, a reverse osmosis module, and an electro-deionization unit. Its core electrical control system (such as a PLC, sensors, and power supply module) is usually integrated into the equipment's control box. Because high-purity water equipment needs to operate continuously for extended periods, the electrical components inside the control box generate a significant amount of heat. If heat dissipation is insufficient, the equipment may overheat, affecting system stability and even damaging components.

[0003] Currently, the control box of high-purity water equipment is often cooled by forced ventilation through a cooling fan. However, the outside air contains dust, particulate matter and other impurities. When the cooling fan draws in air, it easily causes dust to adhere to the filter screen, requiring regular cleaning of the dust on the filter screen to avoid affecting the air quality. However, most current filters are directly fixed at the location of the cooling fan, which means that during the cleaning process, dust can easily be squeezed through the filter screen and enter the control box. This causes dust to adhere to the surface of electrical components, which not only reduces heat dissipation efficiency but may also cause faults such as short circuits or poor contact. Therefore, we propose a dust prevention and cleaning device for high-purity water equipment. Utility Model Content

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This utility model provides, for example Figures 1-5 The dustproof cleaning device shown is used in high-purity water equipment. It includes a main body 101, a dustproof mechanism, and a positioning mechanism. A control box 102 is provided on the front of the main body 101. A cooling fan 103 for introducing external air for heat dissipation is installed on one side of the control box 102. The dustproof mechanism is set on the outer wall of the main body 101. The dustproof mechanism is set in a split manner and is detachably installed on the outer wall of the main body 101, covering the air intake path of the cooling fan 103. The positioning mechanism is set inside the dustproof mechanism to ensure its stable installation and accurate positioning. When the cooling fan 103 is working, the external air must first flow through the split dustproof mechanism and then enter the control box 102 to dissipate heat from the electrical components. When performing dust cleaning and maintenance, thanks to the split design, operators can easily disassemble the entire dustproof mechanism component (especially its dust filter part) from the main body 101 for thorough cleaning or replacement. This design completely avoids the common drawbacks of traditional fixed filter cleaning, namely that cleaning actions (such as blowing or wiping) can easily cause dust to penetrate or bypass the filter gaps and enter the control box 102 in the opposite direction, contaminating precision electrical components or affecting heat dissipation efficiency, thereby significantly improving the operational reliability and maintenance convenience of the equipment.

[0040] The dustproof mechanism includes a fixed ring 201, a movable ring 202, and a filter screen 203. The fixed ring 201 is fixedly connected to the outer wall of the control box 102 and located at the position of the cooling fan 103. The movable ring 202 is sleeved on the outer wall of the fixed ring 201. A positioning mechanism is set between the fixed ring 201 and the movable ring 202. The filter screen 203 is fixedly connected to the inner wall of the movable ring 202. By sleeved on the fixed ring 201, when the cooling fan 103 is working, the outside air needs to be filtered through the filter screen 203 before entering the control box 102 for cooling, so that dust will adhere to the front surface of the filter screen 203.

[0041] The positioning mechanism includes a locking block 304, a slot 301, a sliding groove 302, and a locking slot 303. The locking block 304 is symmetrically fixed to the inner wall of the movable ring 202. The slot 301 is symmetrically opened on the outer wall of the fixed ring 201. The sliding groove 302 is opened on the outer wall of the fixed ring 201, and its interior is connected to the interior of the slot 301. The locking slot 303 is opened on the outer wall of the fixed ring 201, and its interior is connected to the interior of the sliding groove 302. A pressing mechanism is provided inside the locking slot 303. Before placing the movable ring 202 onto the fixed ring 201, align the locking block 304 with the slot 301, then move the movable ring 202 to move the locking block 304 within the slot 301 until it reaches the bottom. Then, rotate the movable ring 202 counterclockwise to move the locking block 304 within the sliding groove 302 until it enters the slot 303. Finally, move the movable ring 202 again to allow the locking block 304 to enter the slot 303, thus completing the inner wall of the movable ring 202 and enabling the dustproof mechanism to work stably.

[0042] The extrusion mechanism includes an extrusion plate 402 and a spring 401. The extrusion plate 402 is movably disposed inside the slot 303. A connecting mechanism is provided on the front side of the extrusion plate 402. The spring 401 is disposed between the front side of the extrusion plate 402 and the inner wall of the slot 303. Through the elastic action of the spring 401, after the block 304 is inserted into the slot 303, the extrusion plate 402 will extrude the block 304. Thus, the block 304 can be stably locked in the slot 303 without being subjected to a large external force, thereby improving the stability of the positioning mechanism.

[0043] The connecting mechanism includes a movable rod 502 and a movable hole 501. The movable rod 502 is fixedly connected to the front of the extrusion plate 402. A spring 401 is sleeved on the outer wall of the movable rod 502. The movable hole 501 is opened in the inner wall of the slot 303. The movable rod 502 is movably inserted into the inner wall of the movable hole 501. A moving mechanism is provided on the front of the movable hole 501. The moving mechanism includes a movable cavity 601, an L-shaped rod 602, a connecting groove 603, and a connecting block 604. The L-shaped rod 602 is fixedly connected to the front of the movable rod 502. The movable cavity 601 is opened inside the fixed ring 201 and communicates with the interior of the movable hole 501. The L-shaped rod 602 is slidably disposed on the inner wall of the movable cavity 601. The connecting groove 603 is opened in the outer wall of the fixed ring 201 and communicates with the interior of the movable hole 501. The L-shaped rod 602 is slidably disposed on the inner wall of the movable cavity 601. The connecting groove 603 is opened in the outer wall of the fixed ring 201 and communicates with the interior of the movable hole 504. The interior of the moving cavity 601 is interconnected. The connecting block 604 is fixedly connected to the end of the L-shaped rod 602. The outer wall of the connecting block 604 is slidably connected to the inner wall of the connecting groove 603. A synchronization mechanism is provided between the two connecting blocks 604. The synchronization mechanism includes a connecting ring 701, which is movably sleeved on the outer wall of the fixed ring 201. One side of the connecting block 604 is fixedly connected to the inner wall of the connecting ring 701. When the dustproof mechanism needs to be assembled, the connecting ring 701 needs to be moved, so that the two connecting blocks 604 move simultaneously. Then, under the connection of the L-shaped rod 602 and the moving rod 502, the extrusion plate 402 is driven to move. The movement of the extrusion plate 402 compresses the spring 401, so that it does not affect the movement of the locking block 304 from the slide groove 302 into the locking groove 303, thereby improving the convenience of the positioning mechanism.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
