Description

Technical Field

[0001] The utility model relates to the technical field of cooling water treatment, in particular to a circulating cooling water filtering device. Background Art

[0002] The circulating water cooling system includes an open circulating cooling water system and a sealed cooling water circulation system. The open circulating cooling water system means that the cooling water absorbs heat in the heat exchanger, dissipates it directly into the atmosphere in the cooling tower or other equipment, and then is sent to the heat exchanger by a circulating water pump to absorb heat, and is reused in this cycle. In the open circulating cooling water system, the circulating cooling water exchanges heat with the air in the mechanical countercurrent cooling tower and also washes the air. Dust, catkins, plastic bags, plastic films and other debris in the air enter the cooling water in the pool during this process. At the same time, old and broken fillers inside the cooling tower and fillers will fall into the pool when they are replaced. If they are not filtered and cleaned in time, it will have a greater adverse effect on subsequent equipment.

[0003] In the existing operation, the water in the pool is usually passed into the filter tank for fine filtration to ensure the water quality and reduce corrosion and blockage of the equipment in the cooling system. However, since the open circulating cooling water system is different from the closed one, there are more large particles of dirt in the pool. If the water in the pool is directly passed into the filter tank for filtration, it will cause frequent blockage inside the filter tank, which not only requires frequent shutdown for maintenance, affecting work efficiency, but also has an adverse effect on the service life of the filter tank. Therefore, there is an urgent need for a circulating cooling water filter device to achieve coarse filtration of the water flow, clean out the large particles of solid dirt in the cooling water in time, and ensure the continuity of subsequent work.

[0021] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0022] like Figures 1 to 4 As shown, a circulating cooling water filtration device described in the utility model includes a pool 1, which is a structure with four sides sealed and an open top. One side of the pool 1 is also open, and a water collecting box 2 is arranged on the open side of the pool 1, and the water collecting box 2 is connected to a water delivery pump 3 for conveying the filtered water entering the water collecting box 2 to the subsequent workstation; a filter port 4 is arranged on the side of the water collecting box 2 close to the pool 1, and the filter port 4 is arranged at the lower part of the water collecting box 2, and a filter screen 5 is arranged outside the filter port 4, and the filter screen 5 is used for coarse filtering of the water flowing into the water collecting box 2, and the filter screen 5 is preferably provided with sealing pads 6 on both sides close to the water collecting box 2 to enhance the tightness of the contact between the filter screen 5 and the side wall of the water collecting box 2; wherein the height of the sealing pad 6 is higher than the height of the pool 1; the filter screen 5 is rotatably connected to the water collecting box 2 so as to discharge the intercepted dirt by regularly controlling the flipping of the filter screen 5, thereby ensuring the filtering efficiency of the filter screen 5.

[0023] In addition, a support plate 7 is vertically arranged at the bottom end of the filter mesh plate 5, and the support plate 7 is a mesh structure. The support plate 7 and the filter mesh plate 5 are in an L-shaped structure, which can provide support and blocking for the trapped dirt when the filter mesh plate 5 is flipped, thereby preventing the dirt from falling during the flipping of the filter mesh plate 5; preferably, an inclined slope is arranged at the end of the support plate 7 away from the filter mesh plate 5, the end of the slope away from the water collecting tank 2 is the bottom end and the end close to the water collecting tank 2 is the high end, so that the dirt can flow smoothly to the filter mesh plate 5; in addition, a dirt collecting trough 8 is also arranged at the top of the water collecting tank 2, which is used to receive the dirt dropped from the filter mesh plate 5, so as to facilitate subsequent centralized cleaning.

[0024] Furthermore, a rotating shaft 9 is provided at the top of the filter screen plate 5, and the rotating shaft 9 is rotatably connected to the mounting plates 10 provided at both sides of the top of the water collecting tank 2 through bearings, wherein one end of the rotating shaft 9 is provided with a driven sprocket 11 after extending from the mounting plate 10, and a driving sprocket 12 driven by a motor is provided at one side of the water tank 1, and the driving sprocket 12 is connected to the driven sprocket 11 through a chain. Through the forward and reverse rotation of the motor and the chain transmission, the filter screen plate 5 can be flipped, thereby realizing the dumping of the filtered dirt into the inside of the dirt collecting tank 8.

[0025] Furthermore, a sealing plate 13 is rotatably provided on the water collecting tank 2 above the inner side of the filter port 4 through a connecting shaft 14, and a flip sprocket is provided after the connecting shaft 14 is movably extended to the outside of the water collecting tank 2 at one end away from the driven sprocket 11, and a driving sprocket is provided at the end of the rotating shaft 9 away from the driven sprocket, and the driving sprocket and the flip sprocket are connected by a driving chain; when working, as the filter screen plate is flipped out of the pool 1, the sealing plate 13 synchronously blocks the filter port 4, and in this process, the plastic rate of flow of water in the pool 1 into the water collecting tank 2 can be reduced, until the filter screen plate 5 is flipped 180 degrees, and the sealing plate 13 completely blocks the filter port 4, thereby preventing the unfiltered water in the pool 1 from continuously flowing into the water collecting tank 2. During this period, a small amount of unfiltered water flowing into the water collection tank 2 will not have a significant impact on the subsequent fine filtering equipment; preferably, in order to further ensure the quality of the water flow entering the water collection tank 2, the present embodiment is provided with an intercepting filter 15 at the filter port 4, and the intercepting filter 15 can perform a temporary filtering function when the filter screen plate 5 is turned over; further ensure the water quality in the water collection tank 2; because as the filter screen plate 5 turns over, the sealing plate 13 will gradually block the filter port 4, so the intercepting filter 15 can filter out less dirt and only play a temporary filtering function. After the intercepting filter 15 is set at the filter port 4, it does not protrude from the plane where the filter port 4 is located, reducing the impact on the filter screen plate 5 after it is reset.

[0026] Furthermore, in this embodiment, the bottom surface of the sewage collecting tank 8 is inclined from high to low from one end close to the pool 1 to the end away from the pool 1, and a blocking door 16 is hinged on the water collecting box 2 on one side of the sewage collecting tank 8 to facilitate the rapid discharge of the sewage collected in the sewage collecting tank 8. Preferably, the bottom of the sewage collecting tank 8 is a filter structure, which can filter the water flow entrained on the sewage, improve the utilization rate of the water flow, and reduce the waste of the water flow.

[0027] Furthermore, the portion of the filter screen plate 5 that is higher than the water collecting tank 2 is sealed, and its surface is a smooth structure, which facilitates the rapid fall of dirt along its smooth surface when pouring; a cleaning brush 17 is slidably arranged on the filter screen plate 5, and the cleaning brush 17 is arranged along the length direction of the filter screen plate 5, and the cleaning bristles can brush the surface of the filter screen plate 5, which can not only clean the surface of the filter screen plate 5, but also reduce the situation where dirt adheres to the filter screen plate 5 and is not easy to fall off. Specifically, a motor-driven threaded screw 20 is provided on one side of the filter screen plate 5, a sliding block 23 is provided on the threaded screw 20, a movable groove 18 is provided on the filter screen plate 5, a connecting plate 19 is provided after the sliding block 23 extends from the movable groove 18, and a cleaning brush 17 is provided on the connecting plate 19; the setting of the connecting plate 19 can ensure the moving stroke of the cleaning brush 17 and the cleaning area covered by the cleaning brush 17 while shortening the distance of the movable groove 18; avoid the movable groove 18 from being too large, and water flows through the movable groove 18 into the side wall of the filter screen plate 5 and contacts with the threaded screw 20, causing corrosion to it, thereby ensuring the normal transmission of the threaded screw 20 and ensuring its service life.

[0028] In order not to affect the flipping of the filter screen plate 5 and prevent the motor from contacting the water flow, the motor is preferably arranged on the side wall of the filter screen plate 5 away from the water collecting box 2. Figure 4 As shown, a driving bevel gear 21 is arranged at the output end of the motor, and a driven bevel gear 22 is arranged on the threaded screw 20 . The driving bevel gear 21 and the driven bevel gear 22 are meshed and transmitted with each other to realize the rotation of the threaded screw 20 .

[0029] When the utility model is in use, the filter screen plate 5 is used to filter the water flow entering the water collecting box 2. After filtering for a period of time, the motor is started to drive the filter screen plate 5 to flip, so that the trapped dirt is dumped into the sewage collecting tank 8. Finally, the filter screen plate 5 is controlled to reset, and the sewage collecting tank 8 is cleaned regularly. The utility model has a simple structure, is easy to operate, and is highly practical.
