Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and more particularly to an industrial electrical equipment control cabinet with a dust removal function. Background Art

[0002] The electrical control cabinet in the prior art is equipped with many electrical components. A large amount of heat is generated when the electrical components are working. Over time, the heat cannot be reduced in time, resulting in excessively high temperature in the electrical control cabinet, affecting the normal operation of the electrical control cabinet, shortening the service life of the electrical control cabinet, and possibly causing safety problems. Therefore, the electrical control cabinet is generally equipped with a cooling fan to dissipate the heat. The cooling fan accelerates the air flow in the electrical control cabinet by drawing external air into the cabinet, thereby achieving heat dissipation. However, the external air contains a large amount of dust, which will pass through the cooling fan into the interior of the electrical control cabinet, thereby causing fire and component failure due to static electricity, resulting in power supply line failure. Most of the existing control cabinets have relatively small spaces, and it is difficult for staff to disassemble the dust filter device at the air inlet, and it is difficult to clean and maintain the dust filter device, which is easy to have an adverse effect on the dust removal effect of the industrial control cabinet.

[0037] Embodiment 1

[0038] like Figure 1-Figure 5 As shown, an industrial electrical equipment control cabinet with a dust removal function comprises a control cabinet body 1, a dust removal chamber 2 and a filter chamber 3. An air inlet 4 is arranged at the bottom end of the control cabinet body 1, a fan 5 is installed inside the air inlet 4, the other end of the fan 5 is connected to an air inlet pipe 6, the other end of the air inlet pipe 6 is connected to a bellows 7, the bellows 7 is installed inside the dust removal chamber 2, the bellows 7 is arranged in a cylindrical shape and air outlets 8 are equidistantly provided on the surface, a filter screen 9 is installed outside the bellows 7, a brush 10 which is height-matched to the filter screen 9 is installed outside the bellows 7, the filter chamber 3 is located above the dust removal chamber 2, the filter chamber 3 is connected to the dust removal chamber 2 through a wind tube 12, ventilation grooves are equidistantly sawn on the surface of the wind tube 12, a wire mesh 13 is installed outside the wind tube 12, the inner bottom end of the dust removal chamber 2 is a circulating water tank, and a small water pump 14 is installed at the bottom of the water tank, a sewage collecting tank 15 is provided on one side of the dust removal chamber 2, and the dust removal A circulating water circuit is formed between the bottom of the dust chamber 2, the water tank inside the control cabinet body 1, and the sewage collecting tank 15 and is driven by a small water pump 14. By providing a bellows 7 and a filter screen 9, the fan 5 draws in external air when the control cabinet dissipates heat, and the drawn air is blown out from the inside of the bellows 7 and drives the bellows 7 to rotate by the reaction force. At this time, the brush 10 on the outside of the bellows 7 scrapes the inner wall of the filter screen 9 driven by the bellows 7, and the dust falls into the circulating water tank below the dust removal chamber 2 under its own gravity, thereby achieving dust removal. By providing a wind tube 12 and a wire mesh 13, the air filtered by the filter screen 9 enters the inside of the wind tube 12 from above and is blown out by the wind tube 12. The water flow in the filter chamber 3 flows in from above the wire mesh 13, and the water flow flows along the surface of the wire mesh 13, thereby performing secondary filtration on the air. Through water curtain filtration, the filtering effect of the air can be effectively improved, making the air cleaner.

[0039] The dirt collecting tank 15 is internally provided with a movable dirt blocking net 16. By providing the dirt blocking net 16, the dust in the dust removal chamber 2 and the filter chamber 3 is removed by the circulating water flow. Here, the dirt blocking net 16 can intercept the dust particles in the circulating water flow, thereby improving the cleanliness of the water flow.

[0040] Two groups of dirt-blocking nets 16 are provided, and both groups of dirt-blocking nets 16 are movably connected to the inside of the dirt-collecting tank 15. By providing two groups of dirt-blocking nets, the filtering effect of the water flow can be further improved. When there is a lot of dust adhering to the surface of the dirt-blocking nets 16, you only need to pull the dirt-blocking nets 16 outwards for cleaning, which is more convenient than traditional cleaning.

[0041] Five groups of brushes 10 are provided, and the five groups of brushes 10 are distributed in a circular array on the side of the bellows 7. Two groups of grooves are opened on the side of the bellows 7, and magnets 11 are installed inside the grooves. A single group of brushes 10 is embedded in the side of the bellows 7 through two groups of iron sliders. A fan blade 25 is installed at the inner exhaust port of the control cabinet body 1, and a tachometer 26 is installed on one side of the fan blade 25. The tachometer 26, the magnet 11, and the internal control system are electrically connected. By providing the magnet 11, the fan blade 25 and the tachometer 26, considering that the brush 10 will be greatly worn if it is continuously scraped, in order not to affect the subsequent cleaning, Here, the brush 10 is sucked inward by the magnet 11 to keep it away from the filter 9. When the dust adhered to the surface of the filter 9 reaches a certain value, the air flux will be reduced. At this time, due to the reduction in wind volume, the rotation speed of the fan blade 25 will decrease. When the speed meter 26 detects that the rotation speed of the fan blade 25 is insufficient, the magnet 11 is energized through the control system to generate a repulsive force on the brush 10. Under the action of the magnet 11, the brush 10 clings to the inner wall of the filter 9, thereby scraping and cleaning it. Here, the filter 9 is cleaned by intelligently controlling the brush 10, which reduces the wear of the brush 10 due to friction on the one hand, and improves the cleaning effect on the other hand.

[0042] The air inlet 4 is arranged at the lower side of the control cabinet body 1 and has a certain curvature. A louver-type baffle is arranged on the outer side of the air inlet 4. By setting the arc-shaped air inlet 4, this air inlet 4 can prevent rainwater from being sucked into the inner wall of the control cabinet body 1 during the circulation of air on rainy days. The arc-shaped groove and the louver baffle can play a role in blocking water.

[0043] A heat conducting plate 27 is installed inside the control cabinet body 1, and the heat conducting plate 27 is connected to the water tank of the control cabinet body 1. By setting the heat conducting plate 27, the heat conducting plate 27 can transfer the heat inside the control cabinet body 1 to the circulating water flow to dissipate heat, thereby improving the heat dissipation effect of the control cabinet body 1.

[0044] Embodiment 2:

By arranging the turbidity sensor 18, the sewage discharge valve 17, the circulation valve 19, the water change valve 20 and the water tank 21, when the circulating water flow in the control cabinet body 1 is relatively turbid, the turbidity sensor 18 controls the sewage discharge valve 17 to open and the circulation valve 19 to close through the control system. At this time, the water flow is discharged from the sewage outlet under the action of the small water pump 14. After the discharge, the sewage discharge valve 17 is closed, and the circulation valve 19 and the water change valve 20 are opened, so that the water in the water tank 21 flows into the circulating water tank, thereby realizing automatic water change.

[0046] Embodiment three:

By arranging the cover plate 22, the float 23 and the limit block 24, the water tank 21 can collect rainwater on rainy days, and rainwater flows in from the water inlet above the water tank 21. When the water in the water tank 21 is full, the float 23 pushes the cover plate 22 upward under the action of buoyancy, thereby blocking the water inlet. This arrangement can automatically close the water inlet after the water tank 21 is filled with water. On the one hand, it can reduce the volatilization of water, and on the other hand, it can prevent external debris from entering the water tank 21. A sunken groove is provided above the water inlet of the water tank 21 corresponding to the top of the control cabinet body 1. By arranging the sunken groove, the water flow can be guided and collected, thereby accelerating the collection efficiency of rainwater.
