Description

Technical Field

[0001] This application relates to the field of water treatment technology, and specifically to a water treatment device for circulating cooling water. Background Technology

[0002] In the operation of current industrial equipment and systems, cooling water is often used to cool the machinery. However, during long-term circulation, the cooling water is continuously evaporated and concentrated, and the organic matter and various ions in it continue to accumulate. Water treatment devices are needed to filter and mix the water with chemicals. However, current water treatment equipment mostly uses manual dosing, which cannot achieve long-term intermittent automatic dosing and results in poor mixing of chemicals and water.

[0003] For example, Chinese utility model patent CN220564456U discloses a circulating cooling water purification machine. Its main technical solution includes: "a purification tank, with a lid on top; a filter screen and an ion exchange resin plate are movably arranged inside the purification tank; a connecting assembly is provided between the lid and the purification tank... a feeding assembly is provided on the lid, the feeding assembly includes a hollow column, a feed hopper, and a valve; the hollow column and the lid are movably connected by bearings; the top of the hollow column is fixedly connected to the feed hopper; and the valve is fixedly installed on the hollow column." This water treatment machine allows for filter plate replacement by opening and closing the top plate, but it cannot achieve long-term automatic chemical dosing and stirring. Its fixed-position stirring results in poor reagent mixing.

[0004] Therefore, this application proposes a water treatment device for circulating cooling water that can simultaneously perform quantitative dosing while fully stirring water and chemicals in different positions in both forward and reverse directions. Utility Model Content

[0005] The purpose of this invention is to provide a water treatment device for circulating cooling water, which aims to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water treatment device for circulating cooling water, comprising a tank, a filter plate, stirring blades, a dosing mechanism, and a hollow tube that drives the stirring blades to reciprocate up and down; the filter plate and the tank are connected by a sealed sliding joint, and a number of circumferentially arranged stirring blades are fixedly connected to the lower circumference of the hollow tube; a fixing ring is fixedly provided in the middle of the tank, and multiple sets of arc-shaped slots are opened on the inner wall of the fixing ring;

[0007] The upper end of the hollow tube is movably connected to the dosing mechanism. An arc-shaped slide bar is provided on the outer periphery of the hollow tube. The arc-shaped slide bar slides in the arc-shaped groove. The hollow tube rotates due to the limit of the fixed ring while being driven to move up and down. The stirring blade moves up and down and back and forth due to the drive of the hollow tube, and at the same time, it rotates in both directions to stir the water. The up and down and back and forth movement of the hollow tube drives the dosing mechanism to discharge the liquid medicine into the tank.

[0008] The hollow tube with an arc-shaped slider reciprocates vertically, causing it to rotate while being limited by a fixed ring. This, in turn, drives the stirring blades to move up and down within the water, rotating in both directions. This thoroughly mixes the chemical solution with the water, preventing the chemical solution from accumulating in any area and effectively improving the mixing efficiency and dissolution effect of the chemical solution and water. Simultaneously, the rotating spray of the chemical solution into the water during the vertical displacement of the hollow tube allows for precise addition of chemicals while further enhancing the mixing efficiency of the chemical solution and water. This effectively reduces the labor intensity of operators and improves the water treatment efficiency of the circulating cooling water.

[0009] Furthermore, a water inlet pipe is installed on one side of the tank, and a water outlet pipe is installed on the other side. Two sets of support columns are bolted to the upper end of the tank, and mounting brackets are bolted to the upper ends of the support columns. A drive assembly is detachably connected to the lower part of the mounting brackets.

[0010] Furthermore, the drive assembly includes an electric push rod and a hinge ring; the upper end of the electric push rod is bolted to the lower end of the mounting bracket, the inner wall of the hinge ring is rotatably connected to the upper side of the hollow tube with a limit, and the output end of the electric push rod is inserted into the side of the hinge ring. The dosing mechanism includes a drug storage tank, a sliding tube, a connecting rod, and a piston; the rear end of the drug storage tank is snapped into the inner side of the mounting bracket, the upper end of the sliding tube is connected to the inside of the drug storage tank through a valve, the lower end of the sliding tube is movably connected to the inner wall of the hollow tube, one end of the connecting rod is inserted into the lower end of the drug storage tank, the other end of the connecting rod is snapped into the piston, the piston is movably connected to the inner wall of the hollow tube, and the connecting rod is positioned inside the sliding tube.

[0011] Furthermore, the movable connection between the sliding tube and the inner wall of the hollow tube is equipped with a dynamic seal to prevent the liquid from leaking out, and a one-way valve is provided on the piston surface. The dosing mechanism also includes a one-way nozzle, which is evenly and circumferentially arranged at the lower end of the hollow tube. A one-way valve is provided inside the one-way nozzle to prevent water in the tank from entering the hollow tube under pressure.

[0012] Compared with existing technologies, it has the following beneficial effects:

[0013] This invention provides a water treatment device for circulating cooling water. A hollow tube with an arc-shaped sliding bar reciprocates vertically, causing it to rotate while being limited by a fixed ring. This, in turn, drives the stirring blades to move up and down within the water body, rotating in both directions. This thoroughly stirs the chemical solution and water, preventing the chemical solution from accumulating in any area and effectively improving the mixing efficiency and dissolution effect of the chemical solution and water. Simultaneously, during the vertical displacement of the hollow tube, the chemical solution is sprayed into the water body, allowing for quantitative addition of chemicals while further enhancing the mixing efficiency of the chemical solution and water. This effectively reduces the labor intensity of operators and significantly improves the water treatment efficiency of circulating cooling water. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1 to 6 As shown, this utility model provides the following technical solution: a water treatment device for circulating cooling water, including a tank 1, a filter plate 2, stirring blades 3, a dosing mechanism 4, and a hollow tube 5 that drives the stirring blades 3 to reciprocate up and down; the filter plate 2 and the tank 1 have a sealed sliding connection, and a number of circumferentially arranged stirring blades 3 are fixedly connected to the lower circumference of the hollow tube 5; a fixing ring 6 is fixedly provided in the middle of the tank 1, and multiple sets of arc-shaped slots 7 are opened on the inner wall of the fixing ring 6;

[0023] The upper end of the hollow tube 5 is movably connected to the dosing mechanism 4. An arc-shaped slide bar 8 is provided on the outer periphery of the hollow tube 5. The arc-shaped slide bar 8 slides in the arc-shaped slot 7. The hollow tube 5 rotates due to the limit of the fixed ring 6 while being driven to move up and down. The stirring blade 3 moves up and down and back and forth due to the drive of the hollow tube 5, and simultaneously rotates in both directions to agitate the water. The up and down movement of the hollow tube 5 drives the dosing mechanism 4 to discharge the liquid medicine into the tank 1.

[0024] See Figure 1 A water inlet pipe 11 is provided on one side of the tank body 1, and a water outlet pipe 12 is provided on the other side of the tank body 1. The water inlet pipe 11 is connected to the return pipe of the circulating cooling water, and the water is pumped into the tank body 1 by a water pump. The water outlet pipe 12 is connected to the circulating cooling water circulation pipe. The water is mixed with the medicine in the tank body 1 and filtered by the filter plate 2. After being treated, the water is pumped back to the circulation pipe.

[0025] The filter plate 2 is a sliding insertion type filter plate 2, and a seal is provided at the connection between it and the housing 1. When it is necessary to clean and replace the filter plate 2, the water inlet pipe 11 is switched to supply water and the water in the housing 1 is completely discharged before the filter plate 2 can be pulled out for processing.

[0026] See Figure 1 The upper end of the housing 1 is bolted with two sets of support columns 13, the upper end of the support columns 13 is bolted with a mounting bracket 14, and the lower part of the mounting bracket 14 is detachably connected with a drive assembly 15.

[0027] Among them, the support columns 13 are symmetrically arranged, the mounting bracket 14 is an L-shaped bracket, and the drive assembly 15 is positioned at the lower part of the mounting.

[0028] As another embodiment, such as Figure 1 and Figure 5As shown, the drive assembly 15 includes an electric push rod 151 and a hinge ring 152; the upper end of the electric push rod 151 is bolted to the lower end of the mounting bracket 14, the inner wall of the hinge ring 152 is rotatably connected to the upper side of the hollow tube 5 with a limit, and the output end of the electric push rod 151 is inserted into the side of the hinge ring 152.

[0029] The hinge ring 152 is rotatably connected to the hollow tube 5 with limiters at the upper and lower ends, so that while the hollow tube 5 rotates relative to the hinge ring 152, the hinge ring 152 can drive the hollow tube 5 to move vertically. When mixing the medicine and water, the output end of the electric push rod 151 pushes and retracts vertically, thereby driving the hinge ring 152 to move back and forth. The movement of the hinge ring 152 drives the hollow tube 5 to move up and down. The arc-shaped slot 7 on the fixed ring 6 limits the arc-shaped slide bar 8, so that the hollow tube 5 rotates alternately in both directions during the up and down movement. This drives the stirring blade 3 to move up and down while rotating alternately in both directions to mix the medicine and water.

[0030] As another embodiment, such as Figure 1 , Figure 3 as well as Figure 6 As shown, the dosing mechanism 4 includes a drug storage tank 41, a sliding tube 42, a connecting rod 43, and a piston 44. The rear end of the drug storage tank 41 is snapped into the inner side of the mounting bracket 14. The upper end of the sliding tube 42 is connected to the inside of the drug storage tank 41 through a valve. The lower end of the sliding tube 42 is movably connected to the inner wall of the hollow tube 5. One end of the connecting rod 43 is inserted into the lower end of the drug storage tank 41, and the other end of the connecting rod 43 is snapped into the piston 44. The piston 44 is movably connected to the inner wall of the hollow tube 5. The connecting rod 43 is positioned inside the sliding tube 42.

[0031] The medicine tank 41 contains a medicine solution for water purification. The medicine solution enters the sliding tube 42 through the valve and is blocked by the piston 44 at the top of the piston 44.

[0032] The sliding tube 42 and the inner wall of the hollow tube 5 are equipped with a dynamic seal to prevent the medicine from seeping out.

[0033] See Figure 6 A one-way valve 45 is provided on the surface of piston 44. This one-way valve 45 also serves as a pressure valve. When the hollow tube 5 moves up and down, the position of piston 44 does not change because the connecting rod 43 and the sliding tube 42 are fixed. The downward movement of the hollow tube 5 causes relative movement between it and piston 44, which in turn creates negative pressure inside the hollow tube 5. The liquid medicine flows from the upper part of piston 44 to the lower part of piston 44 through the one-way valve 45 and gathers at the lower end of hollow tube 5.

[0034] See Figure 3The dosing mechanism 4 also includes a one-way nozzle 46, which is evenly arranged in a circular pattern at the lower end of the hollow tube 5.

[0035] When the hollow tube 5 moves upward, the relative movement of the piston 44 squeezes the liquid medicine out through the one-way nozzle 46. At the same time, the hollow tube 5 is rotating, which drives the one-way nozzle 46 to rotate and spray out the liquid medicine. The sprayed liquid medicine is quickly stirred by the stirring blade 3 and mixed with the water.

[0036] It should be noted that a one-way valve 45 is installed inside the one-way nozzle 46 to prevent water in the housing 1 from entering the hollow tube 5 under pressure.

[0037] Working principle: Circulating cooling water enters the housing 1 through the inlet pipe 11. The electric push rod 151 is activated, causing the hinge ring 152 to reciprocate, which in turn causes the hollow tube 5 to move up and down. The fixed ring 6 limits the arc-shaped slide bar 8, causing the hollow tube 5 to move up and down while the stirring blade 3 rotates alternately in both directions to agitate the water. During the up and down movement, the hollow tube 5 moves relative to the piston 44, resulting in pressure changes inside the hollow tube 5. The one-way valve 45 repeatedly collects the medicine and sprays it into the water through the one-way nozzle 46, so that the medicine and water are fully mixed for purification. The mixed water is filtered through the filter plate 2 and enters the outlet pipe 12 and finally returns to the circulation pipeline.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
