Description
Technical Field
The utility model relates to a cold chain cold storage technology field, especially the cold technique of filling of ice row.
Background
For the articles needing to be refrigerated for medicines and fresh foods, the cold accumulation incubator is a common cold chain transportation scheme. However, the existing cold accumulation insulation can mostly adopts a mode of moving ice rows to cool and insulate, because the ice rows are required to be preprocessed in a refrigeration house before being used, cold energy is absorbed from the refrigeration house, and after the cold energy of the ice rows reaches the requirement of work, the ice rows are placed in the insulation can, so the use and operation process of the cold accumulation insulation can is relatively complicated, the carrying times of the ice rows are more, the labor cost is high, and after the cold energy of the cold accumulation ice rows is released, the ice rows need to be replaced again and packaged again, and at the moment, because the cold source of the ice rows in the insulation can fails, the risk of chain breakage of refrigerated goods in the insulation can is increased. To overcome this deficiency, the utility model has proposed a cold-filling thermal insulation box capable of supplementing the cold quantity of the ice row in the thermal insulation box. However, the former cold charging technology adopts the mode of the exhaust valve, the exhaust valve is generally arranged at the high positions of the upper position and the lower position of the cold charging system, so that the exhaust valve is inconvenient to install, the exhaust is slow, the cold charging medium cannot be quickly filled with cold charging ice rows, and the cold charging speed is slow. And after the cold filling is finished, the cold filling medium is not easy to flow back to the cold filling station, so that the cold filling time is long.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: provided is a cooling device having higher cooling efficiency.
The utility model provides a solution of its technical problem is: a cold charging device comprises a liquid inlet pipeline and a liquid return pipeline, wherein stop valves are arranged on the liquid inlet pipeline and the liquid return pipeline, and quick connectors are arranged at the tail ends of the liquid inlet pipeline and the liquid return pipeline; the device is characterized by further comprising a vacuum pump and an inflation mechanism, wherein the vacuum pump is communicated with the liquid inlet pipeline or the liquid return pipeline, and the inflation mechanism is communicated with the liquid inlet pipeline or the liquid return pipeline.
As a further improvement of the technical scheme, the vacuum pump is communicated with the liquid return pipeline, and a control valve is arranged between the vacuum pump and the liquid return pipeline.
As a further improvement of the technical scheme, a buffer tank is further arranged between the vacuum pump and the liquid return pipeline.
As a further improvement of the technical scheme, the inflation mechanism is communicated with the liquid inlet pipeline, and a second control valve is arranged between the inflation mechanism and the liquid inlet pipeline.
The utility model has the advantages that: the utility model discloses a carry out evacuation treatment to the ice row before filling cold, owing to fill cold ice row medium flow path in the air has taken out, fill cold medium and be full of rapidly and fill cold ice row. And after the cooling is finished, gas is forcibly added through the gas filling port, so that the cooling medium quickly flows back into the cooling station.

Detailed Description
The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
The first embodiment is as follows: referring to fig. 1, a cold charging device comprises a liquid inlet pipeline 1 and a liquid return pipeline 2, wherein stop valves 3 are arranged on the liquid inlet pipeline 1 and the liquid return pipeline 2, and quick connectors 4 are arranged at the tail ends of the liquid inlet pipeline 1 and the liquid return pipeline 2; the device is characterized by further comprising a vacuum pump 5 and an inflation mechanism 6, wherein the vacuum pump 5 is communicated with the liquid inlet pipeline or the liquid return pipeline, and the inflation mechanism 6 is communicated with the liquid inlet pipeline or the liquid return pipeline.
In a further preferred embodiment, the vacuum pump 5 is in communication with the liquid return line 2, and a control valve 7 is provided between the vacuum pump 5 and the liquid return line.
In a further preferred embodiment, a buffer tank 8 is further provided between the vacuum pump 5 and the liquid return line 2.
Further as a preferred embodiment, the inflation mechanism is communicated with the liquid inlet pipeline, and a second control valve 9 is arranged between the inflation mechanism and the liquid inlet pipeline.
The utility model discloses a fill cold charge device's work flow is such: before the cold charging, the liquid inlet pipeline and the liquid return pipeline are simultaneously connected with the cold charging station and the cold charging ice bank. Preferably, the one end of liquid inlet pipe way and return liquid pipeline can be connected with cold filling station relatively fixedly, and the other end of liquid inlet pipe and return liquid pipeline is provided with quick-operation joint, utilizes quick-operation joint, can conveniently fill cold filling station and fill being connected of cold ice row. During working, firstly, the cold-filled ice row is communicated with the liquid inlet pipeline and the liquid return pipeline through the rapid structure, then the stop valves on the liquid inlet pipeline and the liquid return pipeline are closed, so that a closed space is formed among the cold-filled ice row, the liquid inlet pipeline and the liquid return pipeline, then the vacuum pump is opened to vacuumize the closed space, and the vacuum pump takes out air in a medium flow channel in the cold-filled ice row.
After the vacuum pumping is finished, the vacuum pump is closed, then the stop valve is opened, and the cold filling medium of the cold filling station enters the ice bank through the liquid inlet pipeline and then flows back to the cold filling station from the liquid return pipeline. Because the air in the medium flow channel in the cold-charged ice row is pumped out, the cold-charged ice row can be quickly filled with the cold-charged medium, and the ice row is quickly cooled.
After the cooling is completed, one of the stop valves can be closed, and then the gas filling mechanism and the second control valve are opened, for example, the gas filling port is arranged on the liquid inlet pipeline, and gas is forcibly added through the gas filling port, so that the cooling medium quickly flows back into the cooling station.
