Description

Technical Field

[0001] This utility model relates to the field of circulating water scale cleaning technology, and in particular to a scale cleaning device for circulating water systems of refrigeration units. Background Technology

[0002] The circulating water system of a refrigeration unit is one of the many systems in a refrigeration unit. It mainly uses circulating water to achieve heat transfer and temperature control during the refrigeration process. In order to ensure the normal operation of the refrigeration unit, dirt cleaning equipment is usually used to remove dirt from the circulating water system.

[0003] Currently available dirt cleaning equipment typically requires shutting down the entire circulating water system after a period of use to clean the filters inside the equipment. This operation interrupts the normal refrigeration process, reduces actual working efficiency, and the filters in these equipment are prone to accumulating dirt, leading to frequent blockages and affecting the normal flow of circulating water. Therefore, to solve these problems, designing a dirt cleaning device for the circulating water system of a refrigeration unit is something we need to consider. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dirt cleaning device for a refrigeration unit circulating water system. Addressing usage issues, it incorporates a U-shaped connecting plate and a filter screen to effectively clean dirt. Furthermore, by alternating the use of two cleaning chambers, it ensures the continuous operation of the circulating water system. Additionally, it includes two anti-clogging mechanisms that scrape off dirt from the upper part of the filter screen, preventing frequent clogging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dirt cleaning device for a refrigeration unit circulating water system includes a housing. Inside the housing, a first fixing plate divides the inner cavity of the housing into two cleaning chambers. The top of each of the two cleaning chambers is connected to a first branch pipe, the other ends of which are connected to a common water inlet pipe. The bottom of each of the two cleaning chambers is connected to a second branch pipe, the other ends of which are connected to a common water outlet pipe. Grooves are formed on the inner walls of both sides of each of the two cleaning chambers, with the front side of each groove extending forward to the outside. U-shaped connecting plates are installed inside each of the two cleaning chambers, and filter screens are installed on both sides of the two U-shaped connecting plates. Two anti-clogging mechanisms are also included, each used to clean dirt from the corresponding filter screens.

[0007] Preferably, both sides of the two U-shaped connecting plates are fixedly connected with protruding strips, and each protruding strip is slidably connected to the inner wall of the corresponding groove.

[0008] Preferably, the anti-clogging mechanism includes a second fixed plate fixedly connected to the top of the cleaning chamber, a threaded rod rotatably connected between the second fixed plate and the cleaning chamber, a motor installed on the rear side of the housing, the rear end of the threaded rod penetrating the rear inner wall of the cleaning chamber and fixedly connected to the output shaft of the motor, a movable block threadedly connected to the threaded rod, and scraper strips fixedly connected to both sides of the movable block, each scraper strip being attached to a corresponding filter screen.

[0009] Preferably, each of the two second fixing plates is fixedly connected to a guide rod between itself and the corresponding cleaning cavity, and each of the two guide rods is slidably connected to the corresponding moving block.

[0010] Preferably, a sealing door is provided on the front side of each of the two cleaning chambers, and an observation window is provided on the front side of each of the two sealing doors.

[0011] Preferably, both motors are servo motors that can change their rotation direction.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] The system is equipped with a U-shaped connecting plate and a filter screen, which can filter and clean the dirt in the circulating water. When the U-shaped connecting plate needs to be cleaned later, the components in the two cleaning chambers can be used alternately to ensure the continuous operation of the chiller unit's circulating water system and effectively improve the working efficiency of the chiller unit. It is also equipped with two anti-clogging mechanisms. By starting the motor, two scrapers can be moved to scrape off the dirt adhering to the upper part of the filter screen, thereby ensuring that dirt and impurities accumulate at the bottom part of the U-shaped connecting plate and effectively avoid frequent clogging of the filter screen, which would affect the flow of circulating water.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 A dirt cleaning device for a refrigeration unit circulating water system includes a housing 1. The housing 1 has a first fixing plate 2 inside, which divides the inner cavity of the housing 1 into two cleaning chambers 3. The top of each of the two cleaning chambers 3 is connected to a first branch pipe 4, and the other end of each of the two first branch pipes 4 is connected to a water inlet pipe 5. The bottom of each of the two cleaning chambers 3 is connected to a second branch pipe 6, and the other end of each of the two second branch pipes 6 is connected to a water outlet pipe 7. Each of the two first branch pipes 4 and the two second branch pipes 6 is equipped with a switch valve. Each of the two cleaning chambers 3 has a sealing door 18 on its front side. The sealing door 18 can completely block the corresponding U-shaped connecting plate 9, ensuring that the circulating water flows completely through the U-shaped connecting plate 9. Each of the two sealing doors 18 has an observation window 19 on its front side, which allows the staff to easily observe the dirt accumulation on the U-shaped connecting plate 9.

[0022] The two cleaning chambers 3 are provided with grooves 8 on the inner walls of both sides. The front side of each groove 8 extends forward to the outside. Each cleaning chamber 3 is provided with a U-shaped connecting plate 9. Each U-shaped connecting plate 9 is provided with a filter screen 10 on both sides. The filter screen 10 can block dirt and impurities in the circulating water. Each U-shaped connecting plate 9 is fixedly connected with a protrusion 11 on both sides. Each protrusion 11 is slidably connected to the inner wall of the corresponding groove 8.

[0023] The system also includes two anti-clogging mechanisms, both used to clean the dirt on the corresponding filter screens 10. Each anti-clogging mechanism includes a second fixing plate 12 fixedly connected to the top of the cleaning chamber 3. A threaded rod 13 is rotatably connected between the second fixing plate 12 and the cleaning chamber 3. A motor 14 is installed on the rear side of the housing 1. The motor 14 is a servo motor that can change the direction of rotation. The rear end of the threaded rod 13 penetrates the rear inner wall of the cleaning chamber 3 (the penetration point has been sealed) and is fixedly connected to the output shaft of the motor 14. A moving block 15 is threadedly connected to the threaded rod 13. Scraper strips 16 are fixedly connected to both sides of the moving block 15. Each scraper strip 16 is in contact with the corresponding filter screen 10 and can scrape off the dirt and impurities adhering to the upper part of the filter screen 10 to ensure the normal flow of circulating water. A guide rod 17 is fixedly connected between the second fixing plate 12 and the cleaning chamber 3. The guide rod 17 is slidably connected to the moving block 15.

[0024] In this invention, in the initial state, the switch valves in the two first branch pipes 4 and the switch valves in the two second branch pipes 6 are all in the closed state. Before use, the inlet pipe 5 is connected to the outlet of the circulating water system, and the outlet pipe 7 is connected to the inlet of the circulating water system. When in use, first open the switch valve in the first branch pipe 4 on the left and the switch valve in the second branch pipe 6 on the left, so that the circulating water enters the cleaning chamber 3 on the left. The circulating water will pass through the two filter screens 10 on the U-shaped connecting plate 9 in the cleaning chamber 3. During this process, the dirt and impurities in the circulating water will be blocked on the two filter screens 10 and eventually remain in the middle part of the U-shaped connecting plate 9. In this way, the dirt in the circulating water can be filtered and cleaned, ensuring the normal operation of the refrigeration unit.

[0025] During the filtration of circulating water, the motor 14 on the left can be started intermittently, which drives the threaded rod 13 on the left to rotate, causing the corresponding moving block 15 and two scrapers 16 to move in the front and back direction. The two scrapers 16 can scrape off the dirt and impurities adhering to the upper part of the corresponding filter screen 10. With the flow of circulating water, this dirt and impurities can be ensured to accumulate at the bottom part of the U-shaped connecting plate 9, avoiding frequent clogging of the filter screen 10 and affecting the flow of circulating water.

[0026] When a significant amount of dirt and impurities are found to have accumulated on the left-side U-shaped connecting plate 9, open the switch valves in the first branch pipe 4 and the second branch pipe 6 on the right side, while simultaneously closing the switch valves in the first branch pipe 4 and the second branch pipe 6 on the left side. This ensures that the circulating water system within the refrigeration unit continues to operate during the cleaning process. Then, the operator can open the left-side sealing door 18 and move the left-side U-shaped connecting plate 9 forward to remove it. At this point, the operator can clean the accumulated dirt and impurities on the U-shaped connecting plate 9. After cleaning, align the protrusions 11 on both sides of the U-shaped connecting plate 9 with the corresponding grooves 8 and insert them. Then, close the left-side sealing door 18. The entire cleaning process is convenient and quick. The same method applies when cleaning the right-side U-shaped connecting plate 9, ensuring the continuous operation of the refrigeration unit's circulating water system during the cleaning process and improving the refrigeration unit's working efficiency.

[0027] 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.
