Description

New core cold storage

technical field

The invention relates to the technical field of refrigeration, in particular to a novel core cold store.

Background technique

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

SUMMARY OF THE INVENTION

The object of the present invention is to overcome the deficiency of above-mentioned technology, and provide a kind of novel rock core refrigerator.

In order to achieve the above object, the present invention adopts the following technical solutions: a new type of rock core cold storage, characterized in that it includes a cold storage body, an independent insulation box and a refrigeration unit; multiple rows of independent insulation boxes are arranged inside the cold storage body, and each row is independently The insulation box is equipped with a refrigeration unit, and each insulation box is equipped with a cooling fan. A temperature sensor is installed in each independent insulation box. The branch liquid supply pipe of each cooling fan is connected with the main liquid supply tank of the refrigeration unit. The branch return air pipe of the cooling fan is connected with the main return air pipe of the refrigerating 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 one of the independent incubators reaches the upper limit, the electromagnetic valve of the corresponding branch supply liquid pipe is powered on, the refrigeration unit starts at the same time, and the independent incubator begins to cool down; when the temperature in the independent incubator drops to the lower limit, the solenoid valve Power failure, the refrigeration unit stops running, and the cooling is over.

Preferably, the condition for stopping the operation of the refrigerating unit is that the temperature of all independent insulated boxes reaches the set lower limit; the condition for opening is that the temperature of one independent insulated box reaches the upper limit.

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

The beneficial effects of the present invention are as follows: 1. The present invention can realize fully automatic loading and unloading of goods and fully automatic operation of the refrigeration system by individually controlling each incubator. The refrigeration system can be configured in columns and used in columns to realize energy saving and power saving.

2. The present invention controls each incubator individually, so that when there are differences in the stored goods, the required temperature can be adjusted according to the column; when the goods have peculiar smell, since each incubator is closed and independent, there is no need to Will cause taint.

3. Each incubator of the present invention is equipped with a separate cooling fan, and the fan is only started when cooling is required, so the noise of the entire core cold storage is reduced.

Detailed ways

The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. As shown in FIG. 1 , a novel rock core cold storage of the present invention includes a cold storage main body 1 , a cold storage maintenance structure 2 , a refrigeration unit 3 , an independent insulation box 4 , and a cooling fan 5 . The maintenance structure 2 of the cold storage body 1 may be a brick-concrete structure, or other heat preservation 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 spray hard polyurethane foam on the metal surface. The refrigerating unit 3 uses environmentally friendly refrigerants; the unit can be unattended and has low working noise. The condition for the compressor to stop running is that the temperature of all independent insulation boxes reaches the set lower limit; the condition for opening the compressor is that the temperature of one independent insulation box reaches the upper limit. The independent incubator 4 can be provided with different column numbers, the number of incubators in each row and the number of goods in each incubator according to needs and the size of the storehouse. Each column is equipped with a refrigeration unit, and each independent incubator is equipped with a cooling fan. One temperature sensor is installed in each incubator of the air cooler 5, and the control temperature range is ±1°C. When the temperature in any incubator reaches the upper limit, the electromagnetic valve of the liquid supply pipe corresponding to the upper limit is powered 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 will lose power, the refrigeration compressor will stop running, and the cooling will end. The defrosting of the air cooler is an electric heating method, and the defrosting interval and defrosting process are controlled by time. When the defrosting start time is up, stop the compressor, stop the cooling fan, and turn on the heater. When the defrosting time is up, the electric heater is powered off, and the fan and compressor run.

The refrigerating system of a novel rock core cold storage of the present invention is shown in Figure 4, comprises refrigerating compression refrigerating unit 3, air cooler 5, electromagnetic valve 6, thermal expansion valve 7, liquid supply pipe 8, air return pipe 9, condensed water pipe 10. The compressor of the compression refrigerating unit 3 can be fixed frequency or variable frequency. The unit uses environmentally friendly refrigerants, and the unit can be unattended, and the temperature can be lowered when the goods are stored. The electromagnetic valve of the liquid supply pipe corresponding to the temperature in any one of the electromagnetic valve 6 and the thermal expansion box 7 reaches the upper limit is energized and opened, the compressor starts at the same time, and the insulation box begins to cool down; when the temperature in the insulation box drops to the lower limit, the solenoid valve turns off Electricity, the refrigeration compressor stops running, and the cooling is over. The condensed water pipe 10 and the air cooler are defrosted by electric heating, and the defrosting interval and defrosting process are all controlled by time. When the defrosting start time is up, stop the compressor, stop the cooling fan, and turn on the heater. When the defrosting time is up, the electric heater will be powered off, and the fan and compressor will run. The condensed water produced by defrosting is smoothly discharged to the outside of the insulated box.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
