Description

Technical Field

[0001] This utility model relates to the field of explosion-proof refrigeration equipment technology, specifically an explosion-proof refrigeration equipment that is easy to disassemble and maintain. Background Technology

[0002] Refrigeration equipment refers to equipment mainly used for refrigerating food for crew members, refrigerating various types of cargo, and conditioning cabin air during hot weather. It mainly consists of compressors, expansion valves, evaporators, condensers, accessories, and piping. Based on their working principle, they can be divided into compression refrigeration equipment, absorption refrigeration equipment, vapor jet refrigeration equipment, heat pump refrigeration equipment, and electric heating refrigeration devices. Currently, compression refrigeration equipment is the most widely used on ships.

[0003] For example, the authorized patent with publication number CN220366484U (refrigeration equipment with anti-clogging function) includes a refrigeration equipment body and a first filter screen installed on one side of the outer wall of the refrigeration equipment body. A second filter screen is installed on the other side of the outer wall of the refrigeration equipment body. The refrigeration equipment body is equipped with a condenser and a fan inside. The other end of the refrigeration equipment body is equipped with a cleaning mechanism for removing dust from the first and second filter screens. In this utility model, when it is necessary to clean the first and second filter screens, the cleaning sleeve block is moved up and down by the lifting mechanism. Then, with the cooperation of multiple cleaning bristles, the dust attached to the surface of the first and second filter screens can be cleaned, avoiding dust clogging the mesh of the first and second filter screens, which would cause the air intake and exhaust of the refrigeration equipment body to be obstructed. This is beneficial for the air intake and exhaust inside the refrigeration equipment body and helps to extend the service life of the condenser.

[0004] The integrated design of the existing refrigeration equipment is not easy to disassemble, which makes subsequent maintenance and inspection more troublesome. It cannot provide explosion protection, making it less safe to use. Furthermore, the assembly of the evaporator and the refrigeration unit is not convenient, and the exhaust process can easily cause dust and dirt to flow back, which can contaminate the inner cavity of the cabinet. Subsequent dust removal and protection are also quite complicated. Utility Model Content

Explosion-proof mesh covers 27 are provided on both sides of the upper front of the refrigeration cabinet 2 to provide explosion-proof protection for the cabinet. The bottom of the refrigeration cabinet 2 has a detachable support base 7. The control box 5 is located on one side of the lower part of the refrigeration cabinet 2 for convenient intelligent control of the equipment. An evaporator 19 is located at the lower part of the interior of the refrigeration cabinet 2. The evaporator 19 is used to heat and evaporate the refrigerant to produce steam. A condenser 16 is located at the top of the evaporator 19. The condenser 16 is used to condense and liquefy the high-temperature and high-pressure steam. A compression tank 9 is located at one corner of the inner cavity of the refrigeration cabinet 2. The compression tank 9 can compress the steam to a high-temperature and high-pressure state. A dryer 14 is located on one side of the top of the condenser 16 through an exhaust head 15. The dryer 14 is used to dry the exhaust air. A sealing cover 6 is located at the lower part of the front of the refrigeration cabinet 2. The sealing cover 6 is used to seal the lower part of the front of the refrigeration cabinet 2.

[0034] An exhaust pipe 13 is located at the upper part of the inner cavity of the refrigeration cabinet 2. Both sides of the exhaust pipe 13 are connected to the exhaust port 1 through the diverter pipe 8. The bottom end of the exhaust pipe 13 is connected to the dryer tank 14. The compressor tank 9 is connected to one end of the evaporator 19 through the upper gas pipe 12. The upper gas pipe 12 is used to discharge steam into the compressor tank 9. An expansion valve 11 is provided on the upper gas pipe 12. The compressor tank 9 is connected to the condenser 16 through the gas supply pipe 10. A refrigerant charging head is provided at the top of the other end of the evaporator 19.
