Description

Explosion-proof freezer
Technical Field
The invention relates to the technical field of a refrigeration house, in particular to an explosion-proof refrigeration house.
Background
With the rapid development of cold chain logistics in China, people put forward higher demands on the preservation and quality guarantee of goods, and the storage environment conditions of the refrigeration storage directly influence the storage quality of the goods and are of great importance to the preservation and quality guarantee of the goods. In order to ensure the safety and quality of fresh and quick-frozen foods in circulation, on one hand, different types of cold storage and freezing warehouses are required to be continuously reconstructed and newly built, which is a foundation and a core, and meanwhile, a precooling link and a sound cold storage and transportation system are required to be strengthened, the temperature control in the whole process of food circulation is required to be strengthened, and the safety and quality of the foods can be finally ensured only by establishing a sound cold chain logistics system taking the cold storage as a core. The cold chain logistics is a socialized system project, a single enterprise is difficult to realize, the refrigeration facilities of the enterprise should be socialized, the service functions of the cold storage house should extend upwards and downwards, the development of a third-party comprehensive cold chain logistics enterprise should be advocated and promoted, and the cooperation between the cold storage house and a refrigeration transportation enterprise should be advocated and promoted.
The cold storage is a warehouse guide which utilizes a cooling facility to create proper humidity and low temperature conditions, is also called a cold storage and is a place for processing and storing agricultural and livestock products. Therefore, the quality of the refrigerator directly influences the freshness preservation and the quality of the articles placed in the refrigerator.
The existing refrigeration houses have the following problems:
1. the refrigerating principle of the cold storage is that after absorbing heat of a cooled object in an evaporator, a liquid refrigerant is vaporized into low-temperature low-pressure steam, the steam is sucked by a compressor and compressed into high-pressure high-temperature steam and then discharged into a fin condenser, the heat is released to a cooling medium (water or air) in the fin condenser, the refrigerant is condensed into high-pressure liquid, is throttled into the low-pressure low-temperature refrigerant by a throttle valve and then enters the evaporator again to absorb heat and vaporize, and the aim of circulating refrigeration is fulfilled. The compressor is easy to explode due to overhigh temperature in the refrigeration process, the safety is reduced, and meanwhile, the compressor is contacted with air in the use process of the existing refrigeration house, so that the problem of explosion caused by gas entering is easy to occur;
2. at present, through market research, most of storage spaces of warehouses and refrigeration houses at present are found to have ventilation functions, but are all manual mechanical exhaust doors, and cannot be associated with combustible gas and toxic gas in warehouses, and cannot be intelligently and fully automatically exhausted, so that certain explosion hidden danger exists
3. Although the freezer used in China at present adopts an anti-explosion means for partial equipment, the whole anti-explosion performance is imperfect, for example, the freezer does not adopt an anti-explosion ground, is easy to rub with soles and the like, and generates static electricity to cause explosion;
4. at present, in order to ensure the circulation of internal gas, the refrigerator needs to convey external air into the refrigerator, but in the conveying process, a large amount of oxygen carried in the air is easy to convey the oxygen into the refrigerator, once the oxygen content of the refrigerator is too high, the problem of explosion of the refrigerator is easy to occur, at present, the oxygen removing device is generally carried into the refrigerator by people regularly for treatment, and the working efficiency is low;
5. when the cold storage needs to take goods, the whole door of the cold storage is generally required to be opened, so that cold air in the cold storage is quickly removed, the temperature of the cold storage is further increased, and the cold storage needs to be refrigerated again to a proper temperature, so that the energy waste is easy to be serious;
in conclusion, the existing refrigeration house has the problems of easy explosion, energy-saving source waste and low working efficiency and needs to be improved.
