Abstract

A conveyer belt type sub-zero treatment device comprises a heat insulation box body, a liquid nitrogen distributing and sprinkling device and an upper blower, wherein, the liquid nitrogen distributing and sprinkling device is connected with a liquid nitrogen tank, a liquid spraying pipe of the liquid nitrogen distributing and sprinkling device extends into the heat insulation box body, the upper blower is arranged at the upper part of the inner cavity of the heat insulation box body which is provided with a conveyer belt, the front end and the rear end of the conveyer belt are respectively sheathed on a drive wheel which is connected with a drive unit, the front part of the heat insulation box body is provided with a feeding guide plate, and the rear part of the heat insulation box body is provided with an outlet vibrating feed plate, an upper mesh baffle is respectively arranged under the liquid spraying pipe of the liquid nitrogen distributing and sprinkling device and the upper blower, a side mesh baffle is arranged on the side of the conveyer belt, and the lower part of the side mesh baffle is provided with side meshes which are arranged under the upper conveyer belt. The sub-zero treatment device can be applicable to conveyer belt type production line operation.

Description

technical field [0001] The invention belongs to production equipment for modifying materials by using ultra-low temperature, in particular to equipment for cryogenically treating metal materials, and can also be used for processing non-metallic material products such as ceramics, plastics, and rubber. Background technique [0002] The so-called cryogenic treatment of materials is to use a cooling medium to cool the material to a certain low temperature or ultra-low temperature, and keep it for a certain period of time before returning to room temperature to improve the comprehensive properties of the material such as hardness, wear resistance, and corrosion resistance. For metal materials, the cryogenic treatment is to continue the cooling process of the quenched metal material to a certain temperature far below room temperature, so as to promote the further transformation of the retained austenite existing after conventional heat treatment into martensite, Improve and refin...
