Description

New core cold storage

technical field

The utility model relates to the technical field of refrigeration, in particular to a novel rock core cold storage.

Background technique

The core storage three-dimensional warehouse system is generally designed with the function of goods entering and leaving the storage, but the current core storage does not control the temperature, or controls the temperature of the entire storage body. As the temperature requirements for core storage become more and more strict, the storage temperature of different cores is also different, and the three-dimensional warehouse system of the core library in the prior art can no longer meet the needs of the current enterprises.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the above-mentioned technology, and provide a new type of core cold storage.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a new type of rock core cold storage, which is characterized in that: it comprises a cold storage body, an independent thermal insulation box and a refrigeration unit; The independent heat preservation box is equipped with a refrigeration unit, each heat preservation box is equipped with a cooling fan, and a temperature sensor is installed in each independent heat preservation box. The branch air return pipes of each cooling fan are connected with the main air return pipes of the refrigeration unit, and a solenoid valve and a thermal expansion valve are sequentially installed on each branch liquid supply pipe.

Preferably, when the temperature in any independent incubator reaches the upper limit, the solenoid valve of the corresponding branch liquid supply pipe is energized to open, the refrigeration unit starts at the same time, and the independent incubator starts to cool down; when the temperature in the independent incubator drops to the lower limit, the solenoid valve Loss of power, the refrigeration unit stops running, and the cooling ends.

Preferably, the stopping condition of the refrigeration unit is that the temperature of all independent incubators reaches the set lower limit; the opening condition is that the temperature of one independent incubator reaches the upper limit.

Preferably, the cold storage body is externally fixed with a cold storage maintenance structure.

The beneficial effects of the present utility model are as follows: 1. The utility model can realize fully automatic loading and unloading of goods by individually controlling each incubator, and fully automatic operation of the refrigerating system. By configuring and using the refrigerating system in rows, energy saving and Electricity.

2. The utility model can adjust the required temperature by column when the stored goods are differentiated by individually controlling each incubator; when the goods have peculiar smell, each incubator is closed and independent, so Does not cause odor.

3. A separate cooling fan is set up for each insulation box of the present invention, and the fan is started only when cooling is required, so the noise of the entire rock core cold storage is reduced.

Detailed ways

The specific implementation of the present utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments. As shown in FIG. 1 , a new type of rock core cold storage according to the present invention includes a cold storage body 1 , a cold storage maintenance structure 2 , a refrigeration unit 3 , an independent heat preservation box 4 , and a cooling fan 5 . The maintenance structure 2 of the cold storage body 1 may be a brick-concrete structure, or may be other thermal insulation structures. The insulation material of the independent insulation box 4 is rigid polyurethane foam. The panel material is stainless steel and the inner frame is square steel. The cold bridge treatment method is to use anti-corrosion wood and metal surfaces to spray rigid polyurethane foam. The refrigeration unit 3 adopts an environmentally friendly refrigerant; the unit can be unattended, and the working noise is low. The compressor stops running when the temperature of all independent incubators reaches the set lower limit; the opening condition is that the temperature of one independent incubator reaches the upper limit. The independent heat preservation box 4 can be set with different number of columns, the number of heat preservation cabinets in each column, and the number of goods in each heat preservation container according to the needs and the size of the warehouse. Each column is equipped with 1 refrigeration unit, and each independent incubator is equipped with a cooling fan. One temperature sensor is installed in each incubator of the cooling fan 5, and the control temperature range is ±1°C. The solenoid valve of the liquid supply pipe corresponding to the temperature in any incubator reaching the upper limit is energized and turned on, the compressor starts at the same time, and the incubator starts to cool down. ; When the temperature in the incubator drops to the lower limit, the solenoid valve loses power, the refrigeration compressor stops running, and the cooling ends. The air cooler defrosting is electric heating, and the defrosting interval and defrosting process are controlled by time. When the defrosting start time is up, the compressor is stopped, the cooling fan is stopped, and the heater is energized. When the defrost time is up, the electric heater is switched off, and the fan and compressor run.

The refrigerating system of a novel rock core cold storage of the present utility model is shown in FIG. . The compressor of the compression refrigeration unit 3 can be fixed frequency or variable frequency, the unit adopts environmentally friendly refrigerant, the unit can be unattended, and the temperature can be lowered when the goods are stored. Said solenoid valve 6 and thermal expansion 7 any one of the temperature in the incubator box corresponding to the upper limit of the liquid supply pipe solenoid valve is energized to open, the compressor starts at the same time, and the incubator box begins to cool down; when the temperature in the incubator box drops to the lower limit, the solenoid valve fails. Electricity, the refrigeration compressor stops running, and the cooling ends. The condensation water pipe 10 and the air cooler are defrosted by electric heating, and the defrosting interval and defrosting process are controlled by time. When the defrosting start time is up, the compressor is stopped, the cooling fan is stopped, and the heater is energized. When the defrost time is up, the electric heater is switched off, and the fan and compressor run. The condensed water produced by defrosting is smoothly discharged to the outside of the incubator.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. These improvements and Retouching should also be regarded as the protection scope of the present invention.
