Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial cooling water treatment technology, specifically a circulating cooling water purification system. Background Technology
[0002] In the aluminum alloy casting process, the casting mold needs to be cooled with cooling water to accelerate the cooling of the product. The used cooling water needs to be returned to the cooling equipment to ensure the effect of subsequent use. However, the cooling water will produce a lot of scale during long-term use. Scale accumulation leads to a decrease in equipment performance and an increase in energy consumption. Therefore, it is necessary to use purification equipment to purify the cooling water.
[0003] In the prior art, Chinese Patent Application No. CN201911286289.7 discloses an industrial circulating cooling water purification and filtration device, which relates to the field of industrial circulating cooling water treatment technology. It includes a flocculation tank, a first water pump installed on one side of the flocculation tank, a filter box installed on one side of the first water pump, a second water pump installed on one side of the filter box, a purifier installed on one side of the second water pump, an ion exchanger installed on one side of the purifier, and a motor installed at the bottom of the flocculation tank. Through the motor, a first pulley, a second pulley, a third pulley, and a belt, the belt drives the first pulley, the second pulley, and the third pulley to rotate, so that the mixing rods connected to the three sets of pulleys rotate simultaneously, mixing the circulating water and flocculant in the flocculation tank.
[0004] Based on the above information, it can be seen that existing technologies can remove scale from water through filtration. However, in actual use, filter materials (such as filter screens and activated carbon) need to be cleaned manually every time, which is time-consuming and labor-intensive. Utility Model Content
[0005] The purpose of this invention is to provide a circulating cooling water purification system to solve the problem mentioned in the background art that manual cleaning of the filter structure is time-consuming and labor-intensive.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a circulating cooling water purification system, comprising a purification tank with a square structure, an inlet pipe connected to an aluminum alloy casting mold and an outlet pipe connected to the cooling tank fixedly installed on the side of the purification tank, a filter cylinder arranged in the middle of the interior of the purification tank, and a disc-shaped mounting frame fixedly installed at the upper and lower ends of the filter cylinder; a backwash nozzle and a delivery pump fixedly installed inside the purification tank, with the backwash nozzle close to the outer surface of the filter cylinder, and the delivery pump connected to the backwash nozzle via a connecting hose; and a storage tank for storing phosphate solution fixedly installed above the purification tank.
[0007] Preferably, the mounting frame is rotatably mounted between the mounting frame and the purification box, and a driven gear is fixedly mounted on the upper surface of the mounting frame, and the upper end of the mounting frame is rotatably connected to the end of the water inlet pipe.
[0008] Preferably, the driven gear is side-engaged with the driving gear that drives its rotation, and the driving gear is driven by a drive motor fixedly mounted on the upper surface of the purification box.
[0009] Preferably, an internal partition is fixedly installed at the lower end of the filter cartridge, and the internal partition has an overall funnel-shaped structure, and the height of the internal partition is lower than the height of the backflush nozzle.
[0010] Preferably, a three-way connecting valve is fixed at the middle position of the water inlet pipe, and the three-way connecting valve is connected to the storage tank through the delivery pipe, and an electronic flow valve is installed outside the delivery pipe.
[0011] Preferably, stirring blades are fixedly installed on the lower exterior of the mounting frame, and the stirring blades are evenly distributed at equal angles. The stirring blades rotate with the mounting frame to stir the inside of the purification tank, thereby improving the mixing effect of cooling water and phosphate solution.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the circulating cooling water purification system adopts a novel structural design, the specific details of which are as follows:
[0013] 1. The cooling water used in the aluminum alloy casting mold enters the purification box through the inlet pipe. The filter cartridge in the purification box filters out impurities (such as scale). The filtered cooling water enters the cooling box through the outlet pipe, and after cooling, it flows back into the casting mold for reuse.
[0014] Furthermore, the phosphate solution (which is weakly acidic) in the storage tank is delivered to the inside of the filter cartridge through the delivery pipe and the T-connector to dissolve the scale (i.e., soften the water).
[0015] 2. The filtered cooling water is pumped to the backwash nozzle through the connecting hose using a delivery pump. The backwash nozzle pressurizes and sprays the water to backwash the filter cartridge. The impurities that are washed off fall to the bottom of the internal baffle. The funnel-shaped internal baffle then moves the impurities back to the top.
[0016] Furthermore, the drive motor is turned on to drive the drive gear to rotate, which in turn drives the driven gear that meshes with it to rotate. This causes the driven gear to drive the mounting frame to rotate, and the mounting frame drives the filter cartridge to rotate synchronously, so that the backwash nozzle can wash all parts of the upper half of the filter cartridge.

[0024] 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.
[0025] Example 1: Please refer to Figures 1-2 and Figure 6 This embodiment achieves the purpose of filtering impurities in cooling water and provides the following technical solution, specifically: a purification box 1 with a square structure, an inlet pipe 2 connected to an aluminum alloy casting mold and an outlet pipe 3 connected to a cooling box 4 are fixedly installed on the side of the purification box 1, a filter cylinder 6 is set in the middle of the interior of the purification box 1, and a disc-shaped mounting frame 5 is fixedly installed at the upper and lower ends of the filter cylinder 6; a storage tank 16 for storing phosphate solution is fixedly installed on the top of the purification box 1, a three-way connecting valve 14 is fixed in the middle of the inlet pipe 2, and the three-way connecting valve 14 is connected to the storage tank 16 through a delivery pipe 15, and an electronic flow valve is set on the outside of the delivery pipe 15.
[0026] When using the device, first connect the inlet pipe 2 to the aluminum alloy manufacturing equipment (such as casting molds and other equipment that require cooling water). After the cooling water is used up, it is transported to the filter cylinder 6 through the inlet pipe 2. The filter cylinder 6 is used to filter the impurities in the cooling water. The filtered cooling water flows into the cooling tank 4 through the outlet pipe 3 to cool down and then is circulated back to the casting mold for use. During this process, the phosphate solution (weakly acidic) in the storage tank 16 is transported to the inlet pipe 2 through the delivery pipe 15 using the flow valve to mix with the cooling water. The solution replaces the ions in the cooling water to achieve the purpose of softening the cooling water.
[0027] Example 2: Please refer to Figures 3-5 This embodiment achieves the purpose of backwashing the filter assembly and provides the following technical solution, specifically: a backwash nozzle 7 and a delivery pump 8 are fixedly installed inside the purification box 1, and the backwash nozzle 7 is close to the outer surface of the filter cylinder 6. The delivery pump 8 is connected to the backwash nozzle 7 through a connecting hose 9. The mounting frame 5 is rotatably installed between the purification box 1 and the mounting frame 5. A driven gear 10 is fixedly installed on the upper surface of the mounting frame 5, and the upper end of the mounting frame 5 is rotatably connected to the end of the water inlet pipe 2. The driven gear 10 is meshed with the driving gear 11 on the side, which drives it to rotate. The driving gear 11 is driven by a drive motor 12 fixedly installed on the upper surface of the purification box 1. An internal partition 13 is fixedly installed at the lower end of the filter cylinder 6. The internal partition 13 has an overall funnel-shaped structure, and the height of the internal partition 13 is lower than the height of the backwash nozzle 7. An agitator blade 17 is fixedly installed on the lower outer side of the mounting frame 5, and the agitator blade 17 is evenly distributed at equal angles.
[0028] When the device needs cleaning, first stop the flow of cooling water, then turn on the delivery pump 8. Use the delivery pump 8 and connecting hose 9 to lift the cooling water in the purification tank 1 to the backwash nozzle 7. Then use the backwash nozzle 7 to pressurize and spray the cooling water to achieve the purpose of backwashing the filter cartridge 6. The impurities washed off fall below the internal partition 13. The funnel-shaped structure of the internal partition 13 prevents the impurities from being stirred up again. During this process, turn on the drive motor 12. Use the drive motor 12 to drive the drive gear 11 to rotate. At this time, the drive gear 11 drives the driven gear 10 that is meshed with it to rotate. Use the driven gear 10 to drive the mounting frame 5 to rotate. The mounting frame 5 drives the filter cartridge 6 to rotate, so that the backwash nozzle 7 can thoroughly wash the filter cartridge 6.
