Description

Technical Field

[0001] This utility model relates to the field of industrial cooling equipment technology, and in particular to an automatic descaling device for circulating cooling water. Background Technology

[0002] The cooling of circulating water is the result of three processes: evaporative heat dissipation, contact heat dissipation, and radiative heat dissipation, which occur when water comes into contact with air. Evaporative heat dissipation occurs when water forms droplets of various sizes or a very thin water film in the cooling equipment, which increases the contact area with air and prolongs the contact time, thus enhancing the evaporation of water. This allows the water vapor to carry away the heat required for vaporization from the water, thereby cooling the water.

[0003] After prolonged use, water tanks are prone to accumulating impurities, necessitating regular cleaning. Existing methods include manual cleaning and chemical cleaning. Manual descaling is inefficient and labor-intensive: traditional methods, such as scraping with mechanical tools or soaking in chemical agents followed by manual cleaning, are not only time-consuming but also ineffective at completely removing scale from complex pipes and equipment. Chemical descaling has side effects: while some chemical descaling agents can effectively dissolve scale, they may corrode pipes and equipment in the circulating cooling water system, shortening equipment lifespan. Furthermore, the discharge of chemical descaling agents may pollute the environment, requiring additional treatment measures to ensure compliance with environmental protection requirements. Utility Model Content

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Reference Figure 1-4 An automatic descaling device for circulating cooling water includes a water tank 1, an inlet pipe 2 on one side of the water tank 1, an outlet pipe 4 fixedly connected to the side of the water tank 1 away from the inlet pipe 2, and a barrier pipe 3 fixedly connected to one end of the inlet pipe 2. The barrier pipe 3 can be easily disassembled to clean the impurities in the filter pipe 12, but since it is a two-stage filter, there is basically no need to consider its cleaning.

[0022] The barrier tube 3 is equipped with a barrier mechanism for blocking impurities. The barrier mechanism includes a filter tube 12 fixedly connected inside the barrier tube 3. An installation rod 13 is fixedly connected inside the filter tube 12. A piston 14 is slidably connected to the side wall of the installation rod 13. A return spring 15 is elastically connected between the piston 14 and the filter tube 12. The return spring 15 is sleeved on the side wall of the installation rod 13. A pressure sensor is provided on one side of the piston 14. The piston 14 is slidably connected inside the filter tube 12.

[0023] The side wall of the inlet pipe 2 is provided with an installation pipe 5, and the side wall of the installation pipe 5 is fixedly connected to a discharge pipe 6. The discharge pipe 6 is provided with a filter screen, and a rotating rod 16 is rotatably connected through the discharge pipe 6. A drive mechanism for rotating the rotating rod 16 is provided on one side of the water tank 1. The drive mechanism includes a motor 7 fixedly connected to one side of the water tank 1. The output shaft of the motor 7 is fixedly connected to the rotating rod 16. The side wall of the rotating rod 16 located inside the discharge pipe 6 is fixedly connected to an auger blade 10.

[0024] One end of the discharge pipe 6 is slidably connected to a moving pipe 9. The side wall of the moving pipe 9 is provided with a pressure relief valve. One end of the rotating rod 16 is fixedly connected to a reciprocating screw 17, which cooperates with the moving pipe 9. One end of the discharge pipe 6 is provided with a sealing groove, and a sealing ring is fitted inside the sealing groove. The sealing ring cooperates with the moving pipe 9. One end of the moving pipe 9 is fixedly connected to a push plate 8. The side wall of the mounting pipe 5 is fixedly connected to two symmetrically arranged guide rods 11, which pass through and are slidably connected to the push plate 8.

[0025] When using this utility model, such as Figure 1-4 As shown, in use, first connect the barrier pipe 3 and the installation pipe 5 to the inlet pipe 2. Simultaneously, connect the inlet pipe 2 and the outlet pipe 4 to the water tank 1 to provide a pipeline connection for water circulation within the water tank 1. At this time, the water flowing through the installation pipe 5 passes through the filter layer within the installation pipe 5 to complete the filtration of impurities and is collected in a container such as... Figure 2 The installation pipe 5 is positioned above the filter layer and connected to the discharge pipe 6. During this process, water flows through the inlet pipe 2, undergoes secondary filtration through the filter pipe 12, and contacts the piston 14. At this time, with the water pressure remaining constant, the water pressure and the tension of the return spring 15 are balanced. When the water pressure decreases due to blockage by impurities, the return spring 15 drives the piston to move towards the discharge pipe 6. Figure 3 As shown, the piston moves to the left, at which point the piston 14 slides on the mounting rod 13, maintaining stability during the movement of the piston 14. This is achieved by reducing the water inlet range within the filter tube 12 (where, for example...). Figure 3As shown, water flows through the filter pipe 12 to the water tank 1 from the side located to the left of the piston 14. That is, the water inlet area when the piston 14 moves to the left is smaller than the water inlet area when the piston 14 moves to the right. Thus, by adjusting the amount of water entering the water tank 1, the water pressure can be balanced. At this time, the pressure sensor on the piston 14 senses the change in water pressure, indicating that the filter in the installation pipe 5 is clogged, causing the water pressure to change. At this time, the motor 7 can be controlled by the controller to drive the rotation of the rotating rod 16. At this time, the auger blades 10 on the side wall of the rotating rod 16 can push the clogged impurities in the filter layer. At this time, under the sliding connection limit of the guide rod 11 and the push plate 8, the reciprocating screw 17 is threadedly connected to the inner wall of the moving pipe 9, driving the moving pipe 9 to move. When the moving pipe 9 is disengaged from the discharge pipe 6, the discharge pipe 6... Connected to the outside, the water pressure inside the water tank 1 promotes the flow of impurities below the filter layer. With the help of the auger blades 10, the impurities can be automatically discharged. At the same time, as the reciprocating screw 17 rotates, when the leftward limit of the moving pipe 9 is reached, the reciprocating screw 17 can drive the moving pipe 9 to move to the right and reset, thereby causing the moving pipe 9 to overlap with the discharge pipe 6, maintaining the connection between the inlet pipe 2 and the water tank 1. During this process, the sealing groove and sealing ring 9 on the discharge pipe 6 contact and squeeze with the moving pipe 9, which can maintain the seal at the connection between the moving pipe 9 and the discharge pipe 6. At the same time, the pressure relief valve on the side wall of the moving pipe 9 can provide pressure relief for the moving pipe 9, preventing the moving pipe 9 from separating from the discharge pipe 6 due to excessive pressure in the inlet pipe 2 or the water tank 1. Through the above process, the circulation filtration and automatic cleaning of impurities such as scale in the water tank 1 can be achieved.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
