Description

A replaceable antifreeze device for low temperature cold storage door

technical field

The utility model relates to the technical field of antifreeze equipment, in particular to a replaceable antifreeze device for a low-temperature cold storage door.

Background technique

The cold storage door is the passage through which the goods must pass through, and it is also the key part of the cold storage for moisture-proof and air-proof. At present, in the use of low-temperature cold storage, the six sides of the cold storage will have thermal insulation and moisture-proof layers, but the cold storage door needs to be opened and closed frequently. Due to the temperature difference between the inside and outside , will cause water to condense near the cold storage door. When the temperature drops at night, the water will condense into ice, which will freeze the cold storage door and cannot be opened; while the existing rolling shutter cold storage door is made of two layers of PVC cloth curtains. It is formed by filling insulation cotton, and its outer edge is sealed by a sealing strip. In order to prevent freezing, an electric heating device is usually installed on the door frame to heat the door frame to prevent the cold storage door from freezing, but the electric heating only has the temperature next to the heater. For places far away from the heater, the temperature is relatively low, so it is easy to condense fog and freeze. At the same time, electric heating will cause uneven heating of the door frame, which is easy to damage the door frame.

2. The utility model is equipped with a piston, a drain port, and a clamping ring pipe, so that the snapping ring pipe on one side of the heating box is along the direction of the sealing ring, and the water flow at a high place in the heat preservation layer will flow on the back side of the piston. Squeeze, so that the piston rotates and engages with the drain port. At the same time, the water pressure in the heat-preserving layer makes the piston engage with the drain port more stably. After replacing the heating box, insert the snap ring pipe along the drain port. It can continue to be used, so that the heating box can be quickly disassembled and replaced, and the replacement efficiency of the staff is increased.

Detailed ways

The technical scheme in the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the utility model. In addition, the forms of each structure recorded in the following embodiments are only examples, and the aspects involved in the utility model A replaceable antifreeze device for a low-temperature refrigerator door is not limited to the structures described in the following embodiments, and all other embodiments obtained by those of ordinary skill in the art without creative work belong to this invention. The scope of utility model protection.

Referring to Figures 1-4, the utility model provides a replaceable antifreeze device for a low-temperature cold storage door, which consists of the following components:

Assembly instructions: first fix the aluminum alloy door frame 1, then fix the heat preservation layer 2 on the outside of the aluminum alloy door frame 1, and then install the insulation cotton 3 on the outside of the heat preservation layer 2, and then install it on the bottom of the heat preservation layer 2 Fixedly install the bottom insulation layer 6, then fix the piston 13 on one side of the rotating column 12, install the rotating column 12 in the fixed column 11, and then fix the fixed column 11 in the water outlet 14 of the thermal insulation layer 2 directly above, and when the piston 13 is rotated down, it just engages with the drain port 14, and then the sealing ring 15 is fixedly installed at the drain port 14 outside the heat preservation layer 2, and then the heating cover 10 is set on the outside of the heating rod 9, and the It is fixed inside the heating box 4 as a whole, and at the same time, one end of the heating rod 9 is fixedly installed with the timer 7, then the socket 8 is fixedly installed on one side of the timer 7, and finally the inlet and outlet valve 5 is fixedly installed on one side of the heating box 4 , the snap ring pipe 16 is fixedly installed on the side adjacent to the inlet and outlet valve 5 .
