Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a high-efficiency skid machine. Background Technology

[0002] Due to environmental concerns, Freon refrigerants are being phased out at an accelerated pace. High-efficiency skid-mounted refrigerants, due to their high efficiency and environmental friendliness, have long been widely used in the refrigeration industry. However, due to the large ammonia charge and low level of automation in traditional equipment, several accidents have occurred in recent years, restricting the use of ammonia. Therefore, how to reduce the ammonia charge and improve the safety of ammonia systems while ensuring equipment energy efficiency has become a focus of the refrigeration industry.

[0003] The currently published patent, CN210892223U, discloses a plate heat exchanger brine chiller unit. This plate heat exchanger brine chiller unit consists of two parts: a compressor unit skid and a condenser-evaporator skid, making it possible to apply the unit in areas with larger loads. Both the condenser and evaporator use plate heat exchangers, equipped with a U-shaped gas-liquid separator, and a high-pressure float valve is used for throttling control, which greatly reduces the refrigerant charge of the unit. The split skid arrangement facilitates transportation and after-sales operation and maintenance.

[0004] Based on the above search results, a gas filter cartridge is fixedly installed on the compressor skid of the plate heat exchanger brine chiller unit. The gas filter cartridge contains a filter screen, which filters dust and other impurities in the air to prevent them from entering the compressor and causing blockage. However, after prolonged use, a lot of dust will adhere to the surface of the filter screen. The dust will reduce the ventilation efficiency of the filter screen, thereby reducing the ventilation efficiency of the gas filter cartridge and affecting the compressor's refrigerant compression efficiency. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-efficiency skid machine that can solve the problem that after a long period of use, a lot of dust will adhere to the surface of the filter screen, which will reduce the ventilation efficiency of the filter screen, thereby reducing the ventilation efficiency of the gas filter cartridge and affecting the compression efficiency of the compressor for refrigerant.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency skid machine, comprising a mounting base plate and a filter cleaning device; a compressor is fixedly mounted on the top of the mounting base plate, a gas filter cylinder is mounted on the surface of the compressor, and a filter screen is fixedly connected inside the gas filter cylinder; the filter cleaning device comprises a support frame, a rotating shaft, a cleaning brush, and a first bevel gear, the support frame is fixedly connected to the inner wall of the gas filter cylinder, the rotating shaft is rotatably connected to the upper end of the support frame, the cleaning brush is fixedly connected to the left end of the rotating shaft, the cleaning brush is rotatably connected to the inside of the gas filter cylinder, the surface of the cleaning brush contacts the surface of the filter screen, and the first bevel gear is fixedly connected to the right end of the rotating shaft.

[0012] Preferably, a drain pipe is fixedly installed at the output end of the water pump, and the end of the drain pipe away from the water pump extends into the interior of the gas filter cartridge and is fixedly connected to the interior of the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This high-efficiency skid-mounted machine cleans the dust on the surface of the filter screen by rotating the cleaning brush, preventing excessive dust from adhering to the filter screen and reducing the ventilation efficiency of the filter screen.

[0025] Please see Figure 1-4This utility model provides a technical solution: a high-efficiency skid machine, including a mounting base plate 1 and a filter cleaning device. A compressor 2 is fixedly mounted on the top of the mounting base plate 1. A gas filter cylinder 3 is mounted on the surface of the compressor 2. An impurity discharge pipe 4 is fixedly connected to the bottom of the gas filter cylinder 3. A filter screen 5 is fixedly connected inside the gas filter cylinder 3. The filter cleaning device includes a support frame 6, a rotating shaft 7, a cleaning brush 8, and a first bevel gear 9. The support frame 6 is fixedly connected to the inner wall of the gas filter cylinder 3. The rotating shaft 7 is rotatably connected to the upper end of the support frame 6. The cleaning brush 8 is fixedly connected to the left end of the rotating shaft 7 and rotatably connected inside the gas filter cylinder 3. The surface of the cleaning brush 8 contacts the surface of the filter screen 5. The first bevel gear 9 is fixedly connected to the right end of the rotating shaft 7. A rotating rod 10 is rotatably connected to the gas filter cartridge 3. A second bevel gear 11 is fixedly connected to the rear end of the rotating rod 10. The second bevel gear 11 meshes with the first bevel gear 9. The front end of the rotating rod 10 extends to the outside of the gas filter cartridge 3. A drive motor 12 is fixedly installed on the top of the mounting base plate 1. The front end of the rotating rod 10 is fixedly connected to the output end of the drive motor 12. A water pump 13 is fixedly installed on the top of the mounting base plate 1. A water pump pipe 14 is fixedly installed at the input end of the water pump 13. A water storage tank 15 is fixedly installed on the top of the mounting base plate 1. The end of the water pump pipe 14 away from the water pump 13 extends into the interior of the water storage tank 15. A drain pipe 16 is fixedly installed at the output end of the water pump 13. The end of the drain pipe 16 away from the water pump 13 extends into the interior of the gas filter cartridge 3 and is fixedly connected to the interior of the support frame 6.

[0026] An evaporator, a receiver, and a condenser are fixedly installed on the top of the mounting base plate 1. The refrigerant stored inside the receiver is pumped into the compressor 2. The compressor 2 compresses the refrigerant and discharges it into the evaporator for cooling. The evaporator absorbs heat and causes the refrigerant to evaporate. Finally, the refrigerant enters the condenser and dissipates the heat from the refrigerant, condensing it into a liquid.

[0027] When compressor 2 is in use, external gas enters the compressor 2 through gas filter cartridge 3 and passes through filter screen 5 to filter dust and other impurities from the air, preventing them from entering the compressor 2. When a large amount of dust accumulates on the surface of filter screen 5 and needs cleaning, the operator can start drive motor 12. The output end of drive motor 12 rotates, driving rotating rod 10 to rotate. Rotating rotating rod 10 drives second bevel gear 11 to rotate. Rotating second bevel gear 11 drives first bevel gear 9 and rotating shaft 7 to rotate simultaneously. Rotating shaft 7 rotates, causing cleaning brush 8 to rotate in a circular motion to clean the dust from the surface of filter screen 5. After the staff starts the water pump 13, the water pump 13 draws water stored in the water storage tank 15 through the water pumping pipe 14 and discharges it to the surface of the filter screen 5 through the drain pipe 16. This causes the dust and rainwater to condense and settle, and then discharge it to the outside of the gas filter cartridge 3 through the impurity discharge pipe 4. This completes the dust cleaning process on the surface of the filter screen 5. The cleaning brush 8 rotates to clean the dust on the surface of the filter screen 5, preventing the filter screen 5 from having too much dust attached to it, preventing the dust from reducing the ventilation efficiency of the filter screen 5, thereby improving the ventilation efficiency of the gas filter cartridge 3, improving the compression efficiency of the compressor 2 for the refrigerant, and thus improving the refrigeration efficiency of the skid machine.
