Problems solved by technology

The crushing of steel plates causes a lot of energy consumption. Even the power of a general four-shaft crusher is greater than 100KW. In addition, the crushing process produces a lot of noise, which is detrimental to the health of the operators. Therefore, it is necessary to pay attention to this process. Improve and optimize the current recycling process to achieve low-carbon production

Embodiment Construction

[0028] A preferred embodiment of the present invention is described below according to the accompanying drawings, Figure 1~Figure 2 A dismantling and separating method and a dismantling and separating device of a refrigeration equipment are shown. Figure 4 Indicates the composition structure of the plate body in the thickness direction of the refrigeration equipment, and the plate body includes: a steel plate 31 , a foam layer 32 and an inner container 33 . The device includes: a roller device 1 and a sealing device (not shown) for sealing the roller device. The following embodiments are described by taking waste refrigerators as an example.

[0029] The roller device 1 includes rollers arranged in the traveling direction P of the waste refrigerator, and the rollers are composed of rollers arranged up and down with gaps. The rolls comprise stretching rolls 11 and separation rolls 12, the gap between the rolls of the separation rolls 12 is less than the thickness of the min...

Abstract

The invention relates to a refrigeration apparatus disassembling separation method and a disassembling separator thereof. The disassembling separator comprises a roller device and a sealing device for sealing the roller device. The method comprises the following steps: dismounting independent fittings in a refrigeration apparatus, and separating a door body from a box body; removing two opposite side surfaces of the refrigeration apparatus; and carrying out steel plate, a foaming layer and an inner container separation of the door body and the box body in a rolling compacting separation mode by adopting rollers. The door body and the box body are disassembled and separated by using the rollers arranged up and down and having a gap, and the gap is smaller than the thickness of a thinnest plate of the refrigeration apparatus. A generated foaming agent is collected in the rolling compacting separation process of the refrigeration apparatus. The refrigeration apparatus disassembling separation method and the disassembling separator thereof realizes energy saving and environmental protection, and allows a whole steel plate to be obtained while the foaming layer is separated.

Description

technical field [0001] The invention relates to a dismantling and separating method and a dismantling and separating device for refrigeration equipment, in particular to a dismantling and separating method and a dismantling and separating device for recycling foam layers of waste refrigeration equipment. Background technique [0002] Refrigeration equipment such as household refrigerators and freezers often use polyurethane (PU) foam technology to achieve heat preservation. Polyurethane foam has excellent properties such as foamability, low temperature resistance, and biological aging resistance, and has been widely used. Polyurethane foam is a high-molecular polymer made of isocyanate and polyether as the main raw material, under the action of foaming agent, catalyst, flame retardant and other additives, mixed by special equipment, and foamed under high pressure. The coefficient is low, only 0.022~0.024W / (m·K), which is the lowest thermal conductivity among the current insu...
