Description

Technical Field

[0001] This utility model relates to the field of industrial circulating water system purification, specifically to a circulating water filter tank. Background Technology

[0002] In industrial circulating water systems, high turbidity can increase the growth of bacteria and algae, which can affect the cooling effect of the cooler or increase the risk of abnormal operation of the circulating water pump. Therefore, it is essential to study a circulating water filter tank. Summary of the Invention

[0003] The purpose of this invention is to provide a circulating water filter tank that can remove impurities such as dust, suspended solids, and particulate matter entering the circulating water system, thereby reducing turbidity, purifying water quality, reducing the generation of algae and bacteria in the system, purifying the circulating water quality, and improving the heat exchange efficiency of the heat exchanger.

[0004] This utility model is implemented as follows: a circulating water filter tank mainly includes a circulating water inlet pipe 1, a water distributor 2, a tank body 3, a wire mesh 4, a grate plate 5, quartz sand 6, pebbles 7, a filter cap 8, a backwash pipe 9, a drain pipe 10, support legs 11, and a circulating water outlet pipe 12. Its characteristic is that the circulating water inlet pipe 1 is at the top of the tank body 3, the water distributor 2 is inside the tank body 3, and the circulating water inlet pipe 1 is connected to the water distributor 2. The wire mesh 4, grate plate 5, and filter cap 8 are welded to the inside of the tank body 3. The inside of the tank body 3 is filled with quartz sand 6, with the grate plate 5 above the quartz sand 6 and the wire mesh 4 below it. Pebbles 7 are placed between the wire mesh 4 and the grate plate 5 below the tank body 3. Support legs 11 are welded to the outside of the tank body 3. The drain pipe 10 is installed below the tank body 3. The circulating water outlet pipe 12 is directly below the tank body 3, and the backwash pipe 9 is installed on the circulating water outlet pipe 12.

[0005] The purpose of this utility model is achieved as follows: the circulating water enters the distributor 2 through the circulating water inlet pipe 1, and the circulating water is filtered in sequence through the filter screen 4, quartz sand 6, pebbles 7, and filter cap 8. The purified circulating water is discharged through the circulating water outlet pipe 12 to each heat exchanger for heat exchange, and the heat-exchanged circulating water returns to the circulating water system.

[0006] Preferably, pebbles can effectively remove impurities and suspended solids from circulating water, improving filtration efficiency and water quality.

[0007] Preferably, the filter media in the circulating water filter tank is quartz sand, which can effectively remove impurities such as suspended solids, organic matter, colloidal particles, and microorganisms from the circulating water.

[0008] Preferably, the tank is spherical, which allows for better distribution of water to the distributor and reduces the impact of water flow on the tank.

[0009] Preferably, the filter cap can effectively prevent it from being carried into the circulating water system and prevent the loss of quartz sand.

[0010] Preferably, the distributor can evenly distribute the circulating water into the tank, effectively preventing the circulating water from flowing out of the tank and ensuring that the filter media can fully perform its filtration function.

[0011] Preferably, the filter tank is equipped with a backwash pipe, which can clean microorganisms, impurities and other substances attached to the quartz sand, pebbles, wire mesh and filter cap, thereby improving the filtration effect of the quartz sand, pebbles, filter cap and wire mesh.

[0012] Preferably, the grate plate inside the tank not only supports the quartz sand and pebbles, but also fixes the quartz sand during the backwashing process of the filter tank.

[0013] Preferably, the outriggers can fix and support the tank body, and three or four outriggers can be set according to the actual situation. Attached Figure Description

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1 The present invention will be further described below.

[0017] This utility model discloses a circulating water filter tank. The circulating water enters the distributor 2 through the circulating water inlet pipe 1. The circulating water is filtered in sequence through the filter screen 4, quartz sand 6, pebbles 7, and filter cap 8. The purified circulating water is discharged through the circulating water outlet pipe 12 to various heat exchangers for heat exchange. The circulating water after heat exchange returns to the circulating water system.
