Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically a water treatment device for an open circulating water system. Background Technology

[0002] An open-loop water cooling system is a circulating cooling system that uses natural water sources such as rivers and lakes as the cooling medium. In this system, used hot water releases heat through a cooling tower or other cooling equipment and is then returned to the system for reuse. The characteristic of this system is its openness; the cooling water is in direct contact with the atmosphere during circulation, making it susceptible to contamination and potential water quality changes, such as scaling and corrosion.

[0003] An open-loop water system includes a cooling tower, which is used to lower the temperature of the circulating water, usually by evaporation of the water; a circulating water pump, which is responsible for driving the cooling water to circulate in the system, ensuring that the water can flow through the equipment that needs to be cooled; and a heat exchanger, which in an open-loop water system is used to transfer heat from one fluid to another, usually from hot water to cooling water.

[0004] After cooling water is drawn from the water source, it is first filtered to remove suspended solids and other impurities, then treated for water quality, and then transported to the cooling system. However, during water pumping, the pump head is easily clogged by some aquatic plants, garbage and other debris, requiring staff to clean it frequently. In view of this, this application proposes a water quality treatment device for an open circulating water system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water treatment device for open circulating water systems, which has the advantages of automatically cleaning the pump head and solves the problem that the pump head is easily clogged by aquatic plants, debris and other impurities during water pumping, requiring frequent cleaning by staff.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water treatment device for an open circulating water system, comprising a treatment platform, a treatment tank fixedly installed on the top of the treatment platform, and a bidirectional water pump for pumping water. A water pumping filter head is fixedly installed at one end of the bidirectional water pump, and a branch pipe is fixedly installed at the other end of the bidirectional water pump. A water storage tank is fixedly installed at one end of the branch pipe. An input pipe is fixedly installed on the top of the treatment tank. A filter is connected to a flange at one end of the input pipe, and the bottom end of the filter is connected to a flange at the other end of the branch pipe.

[0007] A first control valve is fixedly installed on the surface of the branch pipe connecting to the filter, and a second control valve is fixedly installed on the surface of the branch pipe connecting to the water storage tank.

[0008] Furthermore, one end of the water pump filter head is fixedly installed with a connecting pipe that is fixedly connected to one end of the bidirectional water pump, and the surface of the water pump filter head is provided with a number of filter holes.

[0009] Furthermore, a rotating shaft is rotatably mounted on the inner top wall of the processing box, and stirring blades are fixedly mounted on the surface of the rotating shaft.

[0010] Furthermore, a stirring motor is fixedly installed on the top of the processing box, and the output shaft of the stirring motor is fixedly connected to the top end of the rotating shaft.

[0011] Furthermore, a feeding hopper is fixedly installed on the top of the processing box, a transfer box is fixedly installed on the top of the processing platform, and a U-shaped connecting pipe with one end connected to the bottom of the transfer box is fixedly installed on the bottom of the processing box.

[0012] Furthermore, a connecting valve is fixedly installed on the surface of the U-shaped connecting pipe, a controller is fixedly installed on the top of the processing platform, and a water quality analyzer is fixedly installed on the inner side wall of the processing tank.

[0013] Furthermore, a water outlet pipe is fixedly installed on one side of the transfer box, support legs are fixedly installed at the four corners of the bottom of the processing platform, and an observation window is fixedly installed on the front of the processing box.

[0014] Compared with the prior art, this utility model provides a water treatment device for an open circulating water system, which has the following beneficial effects:

[0015] This water treatment device for open-loop circulating water systems uses a branch pipe installed at one end of a bidirectional water pump. One end of the branch pipe is connected to a water storage tank, and the other end is connected to a treatment tank. The first and second control valves are opened simultaneously to fill the water storage tank with water. Then, the second control valve is closed. When the filter holes of the pump head are blocked, the first control valve is closed and the second control valve is opened, causing the bidirectional water pump to work in reverse, pumping water out of the water storage tank and backflushing the pump head to dislodge debris such as aquatic plants and waste that clog the pump head. This solves the problem that the pump head is easily blocked by aquatic plants and waste during pumping, requiring frequent cleaning by staff. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-3 A water treatment device for an open-loop circulating water system includes a treatment platform 1, a treatment tank 2 fixedly installed on top of the treatment platform 1, and a bidirectional water pump 3 for pumping water. A pumping filter head 4 is fixedly installed at one end of the bidirectional water pump 3, and a branch pipe 5 is fixedly installed at the other end of the pump 3. A water storage tank 6 is fixedly installed at one end of the branch pipe 5. An inlet pipe 7 is fixedly installed on the top of the treatment tank 2, and a filter 8 is flanged at one end of the inlet pipe 7. The bottom end of the filter 8 is flanged at the other end of the branch pipe 5. Water entering the treatment tank 2 undergoes dual filtration through the pumping filter head 4 and the filter 8.

[0022] A first control valve 51 is fixedly installed on the surface of the connection section between branch pipe 5 and filter 8, and a second control valve 52 is fixedly installed on the surface of the connection section between branch pipe 5 and water storage tank 6. When the bidirectional water pump 3 operates in the forward direction, it draws water up and simultaneously opens the first control valve 51 and the second control valve 52, drawing the water into the treatment tank 2 and the water storage tank 6 respectively. When the water storage tank 6 is full, the second control valve 52 closes. When the water pumping filter head 4 is blocked, the first control valve 51 closes and the second control valve 52 opens, causing the bidirectional water pump 3 to reverse and draw water out of the water storage tank 6, backflushing the water pumping filter head 4 and washing away the water plants, debris, and other impurities that are clogging the water pumping filter head 4.

[0023] Secondly, a connecting pipe 41 is fixedly installed at one end of the water pump 4 and fixedly connected to one end of the bidirectional water pump 3, and a number of filter holes 42 are opened on the surface of the water pump 4.

[0024] Meanwhile, a rotating shaft 9 is rotatably installed on the inner top wall of the processing box 2, and a stirring blade 10 is fixedly installed on the surface of the rotating shaft 9.

[0025] A stirring motor 11 is fixedly installed on the top of the treatment tank 2, and the output shaft of the stirring motor 11 is fixedly connected to the top end of the rotating shaft 9. The stirring motor 11 drives the rotating shaft 9 to rotate, which in turn drives the stirring blades 10 to rotate in the treatment tank 2, thus stirring the water in the treatment tank 2.

[0026] Meanwhile, a feeding hopper 12 is fixedly installed on the top of the processing box 2, a transfer box 13 is fixedly installed on the top of the processing platform 1, and a U-shaped connecting pipe 14 with one end connected to the bottom of the transfer box 13 is fixedly installed on the bottom of the processing box 2.

[0027] A connecting valve 15 is fixedly installed on the surface of the U-shaped connecting pipe 14, a controller 16 is fixedly installed on the top of the treatment platform 1, and a water quality analyzer 17 is fixedly installed on the inner wall of the treatment tank 2. The water treatment agent is fed into the treatment tank 2 through the feeding hopper 12. The stirring motor 11 drives the stirring blades 10 to stir the water. The water quality analyzer 17 monitors the water quality in real time. When the water quality meets the standards, the controller 16 opens the connecting valve 15, allowing the treated water to flow into the transfer tank 13.

[0028] Secondly, a water outlet pipe 18 is fixedly installed on one side of the transfer box 13, and support legs 19 are fixedly installed at the four corners of the bottom of the treatment platform 1. An observation window 20 is fixedly installed on the front of the treatment box 2. The water processed in the transfer box 13 is output through the water outlet pipe 18 for use.

[0029] In this embodiment, when the water storage tank 6 is filled with water, and the water pumping filter head 4 is blocked, the first control valve 51 is closed, the second control valve 52 is opened, and the bidirectional water pump 3 reverses to pump out the water from the water storage tank 6 and backflush the water pumping filter head 4, washing away the water plants, debris and other impurities that block the water pumping filter head 4, thus reducing the number of times staff need to clean the blocked water pumping filter head 4.

[0030] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
