Description

Technical Field

[0001] This utility model relates to the field of refrigeration unit technology, and in particular to a refrigeration unit. Background Technology

[0002] In modern industrial and large-scale commercial settings, refrigeration units, as core temperature control equipment, directly impact production and operational efficiency due to their operational stability. However, during long-term operation, the circulating water system, due to continuous heating, water evaporation, and contact with air, causes calcium and magnesium ions to precipitate and form scale, which adheres to the surfaces of critical components such as heat exchangers and condensers. Scale has a much lower thermal conductivity than metal materials; for every 1 mm increase in scale thickness, heat transfer efficiency can decrease by 20%-30%, directly leading to a surge in energy consumption, reduced cooling performance, and frequent equipment malfunctions such as high-pressure alarms and insufficient cooling capacity, increasing maintenance costs and energy consumption.

[0003] Traditional methods of scale removal have significant drawbacks: while chemical acid washing can dissolve scale, strong acids are highly corrosive to the metal substrate of the equipment, and repeated acid washing can easily lead to thinning and perforation of the equipment, and improper waste liquid treatment can easily cause environmental pollution; manual mechanical cleaning requires disassembling the equipment, which is labor-intensive, inefficient, and the disassembly and assembly process can easily introduce new faults, making it difficult to meet the needs of large refrigeration systems to quickly restore operation.

[0004] To address the aforementioned issues, ultrasonic technology, with its high efficiency and environmental friendliness, has emerged as a new direction for solving limescale problems. The cavitation effect generated when ultrasound propagates in a liquid creates minute impact forces that precisely remove limescale particles from equipment surfaces. Combined with limescale filtration and collection systems, real-time interception and centralized treatment of limescale can be achieved, avoiding the drawbacks of traditional methods while meeting the dual demands of modern industry for efficient equipment operation and green maintenance.

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.

[0023] Please see Figure 1-3 A refrigeration unit includes a condenser 1 located below the main body 6. The condenser 1 has multiple condensing tubes arranged inside it. The condenser 1 has a water inlet 11 and a drain outlet 12. The drain outlet 12 is equipped with a filter mechanism 4. A guide rail 7 is arranged along the length of the condenser 1 on its outer side. An ultrasonic generator 2 is slidably connected to the guide rail 7. The ultrasonic generator 2 is driven by a drive mechanism 3 to slide back and forth along the guide rail 7. The ultrasonic waves break up and remove the scale from the condensing tubes 13 and the inner wall of the condenser 1. During the cleaning process, cooling water enters the condenser 1 through the water inlet 11. Under the action of the water flow, the scale that has been removed flows to the drain outlet 12 and is then filtered by the filter mechanism 4 before being discharged.

[0024] Furthermore, the drive mechanism 3 includes a lead screw 31 arranged along the length of the condenser 1, a motor 32 located at the end of the lead screw 31, and a fixing member 33 threadedly connected to the lead screw 31; the fixing member 33 is fixedly connected to the ultrasonic generator 2; both ends of the lead screw 31 are connected to the bracket of the condenser 1. When the ultrasonic generator 2 needs to move back and forth, the motor 32 is turned on, and the motor 32 drives the lead screw 31 to rotate back and forth, thereby driving the fixing member 33 to move back and forth, and in turn driving the ultrasonic generator 2 to slide back and forth on the guide rail 7, evenly acting on every corner of the condenser 1.

[0025] Furthermore, the motor 32 is mounted on the condenser 1 via the mounting bracket 5, providing a stable support platform for the motor 32. This ensures the stability of the motor 32 during operation and reduces the risk of performance degradation or failure due to vibration or displacement.

[0026] Furthermore, the filtration mechanism 4 includes a pipe 41 connected to the drain outlet 12 and a filter screen 42 located at the outlet end of the pipe 41. Scale is intercepted and filtered through the filter screen 42, and clean water is discharged outside the condenser 1 for recycling.

[0027] Furthermore, the filtration mechanism 4 also includes a scraper 43 located below the filter screen 42 and a transmission mechanism 44 that drives the scraper 43 to rotate along the bottom surface of the filter screen 42. The scraper 43 is in contact with the filter screen 42 and rotates to scrape off the scale on the filter screen 42, preventing the filter screen 42 from becoming clogged. The scale falls into the pipe 41 and can be cleaned periodically.

[0028] Furthermore, the transmission mechanism 44 includes a first bevel gear 441 and a second bevel gear 442 that mesh with each other; wherein, the first bevel gear 441 is connected to the drive mechanism 3 via a first transmission shaft 443, and the second bevel gear 442 is connected to the scraper 43 via a second transmission shaft 444. The first transmission shaft 443 and the second transmission shaft 444 are set at 90° to each other. The first transmission shaft 443 is coaxially connected to the lead screw 31. Under the action of the motor 32, the first transmission shaft 443 rotates synchronously with the lead screw 31, thereby sequentially driving the first bevel gear 441, the second bevel gear 442, and the second transmission shaft 443 to rotate, thereby realizing the rotation of the scraper 43.

[0029] Furthermore, the filter mechanism 4 also includes a drain port 45 located at the bottom of the pipe 41 and a cover 46 sealed on the drain port 45. The drain port 45 is used for periodically cleaning scale residue, and the cover 46 is sealed to the drain port 45.

[0030] Furthermore, a step 411 is provided at the connection between the pipe 41 and the filter screen 42. This step 411 facilitates the fixing of the filter screen 42.

[0031] Furthermore, the inlet 11 is located below the outlet 12. Cooling water enters the condenser 1 at a relatively low temperature, its level gradually rises, and its temperature increases upon contact with the condenser tubes 13, before being discharged from the higher outlet 12. The location of the inlet 11 below the outlet 12 ensures sufficient residence time for the cooling water in the condenser 1, allowing for more effective heat absorption from the condenser tubes 13 and improved cooling efficiency. The lower location of the inlet 11 also helps to create a uniform water flow distribution within the condenser 1. Additionally, the inherent flow velocity of the entering cooling water prevents loose scale from settling to the bottom, allowing it to flow out through the outlet 12 with the water flow.

[0032] During operation, the motor 32 is periodically turned on, driving the ultrasonic generator 2 to reciprocate along the condenser tube 13, evenly breaking up the scale on the wall of the condenser tube 13. Under the action of the motor 32, the rotation of the lead screw 31 also drives the transmission mechanism 44, ultimately rotating the scraper 43 to prevent the filter screen from clogging. When stopping the machine, the cover 46 can be opened to clean the scale.
