Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a device for preventing blockage of the outlet of a cooling tower. Background Technology

[0002] During the cooling process of circulating water, the cooling tower discharges the cooled water through the outlet. Since the water contains impurities, these impurities will enter the water pump and cooling equipment during the circulation process, causing wear, blockage and other damage to the equipment, reducing the service life of the equipment. Therefore, it is usually necessary to install a filter screen at the outlet.

[0003] During use, the filter screen and the filtered impurities need to be cleaned regularly to ensure smooth water circulation. However, cleaning the filter screen and impurities requires shutting down the cooling tower and stopping water circulation before cleaning can be performed. After cleaning, the cooling tower can be restarted. Once the cooling tower is shut down, the entire production line will be affected, thus reducing work efficiency. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a cooling tower outlet anti-clogging device, which effectively solves the problem that the cooling tower needs to be shut down when cleaning the filter screen and impurities, which affects the entire production line and reduces work efficiency.

[0005] The technical solution of this utility model is as follows: it includes an anti-clogging component, which includes a housing. Two movable columns are movably arranged inside the housing. The two movable columns and two opposite side plates of the housing together form a chamber. A partition is provided inside the chamber to divide the chamber into two cavities. The two movable columns slide in contact with the two ends of the partition. A filter screen is connected between the partition and the opposite side plate of the housing. Each filter screen divides its cavity into a filtration chamber and a discharge chamber. Each movable column is provided with through holes on both sides of the partition. A branch pipe is connected to each filtration chamber and discharge chamber on the housing. When the filtration chamber and discharge chamber in one cavity are connected to the corresponding external branch pipe through the corresponding through hole, the filtration chamber and discharge chamber in the other cavity are disconnected from the corresponding external branch pipe through the two movable columns. The two branch pipes corresponding to the filtration chamber are connected to the inlet main pipe, and the two branch pipes corresponding to the discharge chamber are connected to the outlet main pipe.

[0006] This invention can switch the drainage flow direction inside the box. When it is necessary to clean one of the filters, simply move two moving columns simultaneously to disconnect the cavity containing this filter from the corresponding external branch pipe through the two moving columns. At this time, the cavity containing the other filter is connected to the corresponding external branch pipe through the corresponding through hole. Without shutting down the cooling tower, the filter and impurities in the cavity disconnected from the corresponding branch pipe can be cleaned. The operation is simple, convenient and quick, and improves work efficiency. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0013] like Figures 1-4 As shown, a cooling tower outlet anti-clogging device includes an anti-clogging component, which includes a housing 1. The housing 1 is a hollow cuboid with an open top. Two movable columns 5, both rectangular columns, are movably installed inside the housing 1. The two movable columns 5 and two opposite side plates of the housing 1 together form a chamber. A partition 8 is provided inside the chamber to divide it into two cavities. The two movable columns 5 are in sliding contact with the two ends of the partition 8. A filter screen 9 is connected between the partition 8 and the opposite side plate of the housing 1. Each filter screen 9 filters out the contents of its respective cavity. The cavity is divided into a filtration chamber and a discharge chamber. Each movable column 5 is provided with through holes 6 on both sides of the partition plate 8. Each filtration chamber and discharge chamber on the box body 1 is connected to a branch pipe 3. The branch pipe is an L-shaped pipe. When the filtration chamber and discharge chamber in one cavity are connected to the corresponding external branch pipe through the corresponding through holes 6, the filtration chamber and discharge chamber in the other cavity are disconnected from the corresponding external branch pipe through the two movable columns 5. The two branch pipes corresponding to the filtration chamber are connected to the inlet main pipe 2, and the two branch pipes corresponding to the discharge chamber are connected to the outlet main pipe 4.

[0014] The anti-clogging component is installed between the outlet of the cooling tower and the spray pump. The inlet end of the main water inlet pipe 2 is connected to the outlet of the cooling tower, and the outlet end of the main water outlet pipe 4 is connected to the spray pump.

[0015] The tops of the two cavities are respectively sealed with cover plates 7 connected to the housing 1.

[0016] The bottom of the movable column 5 contacts the inner bottom surface of the box 1, the top contacts the cover plate 7, and the back sides of the two movable columns 5 slide in contact with the inner wall of the box 1 respectively.

[0017] The moving column 5, filter screen 9, and partition 8 are at the same height.

[0018] The partition 8 is fixed at the bottom of the chamber, and the filter screen 9 and the partition 8 are connected in a cross shape. The partition 8 is perpendicular to the two moving columns 5.

[0019] When the filter chamber and discharge chamber within the cavity are disconnected from their corresponding external branch pipes via two movable columns 5, the two branch pipes blocked by the two movable columns 5 are staggered with the two adjacent through holes (e.g., Figure 3 The upper two branch pipes and the upper two through holes).

[0020] The two movable columns 5 are driven by the driving mechanism to move forward or backward synchronously, and the two ends of the movable columns 5 respectively move through the two side plates of the box body 1.

[0021] The drive mechanism includes two connecting plates 13, which are located outside the housing 1. Each connecting plate 13 is connected to the ends of two moving columns 5 located in the same direction at both ends. A screw 10 with both ends extending is threaded onto any connecting plate 13. One end of the screw 10 is rotatably connected to the housing 1, and a handwheel 11 is connected to the other end.

[0022] When the filter chamber and discharge chamber in the cavity are connected to the corresponding external branch pipes through the corresponding through holes 6, the connecting plate 13 on the same side of the cavity contacts the housing 1, which facilitates the accurate alignment of the through holes 6 with the corresponding external branch pipes, thereby ensuring the connection between the through holes 6 and the corresponding external branch pipes.

[0023] The cover plate 7 is detachably connected to the box body 1. Specifically, the cover plate 7 is connected to the top of the box body 1 by bolts 12.

[0024] When using, Figure 4Taking this as an example, when the filter screen 9 and impurities in the front cavity need to be cleaned, the handwheel 11 is rotated to make the screw 10 rotate. The screw 10 drives the two moving columns 5 to move forward synchronously through the connecting plate 13 until the front side wall of the rear connecting plate 13 contacts the rear side wall of the housing 1. The screw 10 is then stopped rotating. At this time, the through hole 6 at the front of the left moving column 5 and one end of the branch pipe 3 at the front of the left are misaligned, and the through hole 6 at the front of the right moving column 5 and one end of the branch pipe 3 at the front of the right are misaligned. That is, the front cavity is in a closed state. The through hole 6 at the rear of the left moving column 5 and one end of the branch pipe 3 at the rear of the left are in a connected state, and the through hole 6 at the rear of the right moving column 5 and one end of the branch pipe 3 at the rear of the right are in a connected state. With the rear cavity open, water discharged from the cooling tower outlet enters the filter chamber within the rear cavity through the left rear branch pipe 3 and the through hole 6 at the rear of the left movable column 5. After being filtered by the filter screen 9, it enters the rear discharge chamber and is then discharged through the through hole 6 at the rear of the right movable column 5 and the right rear branch pipe 3. After the water flow switching is completed, loosen the bolt 12 and open the cover plate 7 above the front filter screen 9 to clean the filter screen 9 and impurities in the front cavity. When the filter screen 9 and impurities in the rear cavity need to be cleaned, rotate the handwheel 11 in the opposite direction until the rear side wall of the front connecting plate 13 contacts the front side wall of the housing 1. The rear cavity is then closed, and the cover plate 7 above the rear filter screen 9 can be opened.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
