Cold slag crusher

Abstract

The invention belongs to the field of research on waste slag treatment technology, and in particular relates to a cold slag crusher. The cold slag crusher comprises a feed bin and a roller connected with the feed bin. A load bearing device and a transmission device are arranged on the side wall of the roller, and a cooling chamber is erected in the middle of the roller. A cooling water circulationsystem is arranged in the cooling chamber, and a sorting chamber is arranged at the front end of the roller. The cold slag crusher has the beneficial effects that the load bearing device of the roller adopts a loose sleeve type structure, and a load bearing ring and a bracket are connected in a loose sleeve mode, so that the cracking of a roller body and the load bearing ring due to heat expansion and cold contraction can be effectively avoided by the connection. Meanwhile, the roller body and the cooling chamber are arranged at intervals, and cooling water in the cooling chamber is preventedfrom flowing out by the arrangement of a water retaining ring, so that the sealing connection of the roller body and the cooling chamber is avoided, and the resistance of roller rotation is reduced.

Description

technical field [0001] The invention belongs to the technical research field of waste slag treatment, and in particular relates to a cold slag crusher. Background technique [0002] Metal raw materials and auxiliary materials (aluminum waste, aluminum chips, waste aluminum) are passed through the rotary furnace to obtain aluminum liquid, and the remaining aluminum slag also contains some metal aluminum. In order to better obtain the metal aluminum in the aluminum slag, a cold slag is needed The crusher is used for cooling, crushing and sorting the aluminum slag, so as to recycle and reuse the aluminum slag. [0003] The existing cold slag crusher is simple and rough, and the electrical control is simple. The fixing method of the load-bearing ring of the drum is welding. Because the temperature of the aluminum slag is 300-400 ° C, and there is cooling water outside the cylinder, the welding part is hot and cold, which is particularly easy to cause load-bearing Ring cracking ...

[0003] The existing cold slag crusher is simple and rough, and the electrical control is simple. The fixing method of the load-bearing ring of the drum is welding. Because the temperature of the aluminum slag is 300-400 ° C, and there is cooling water outside the cylinder, the welding part is hot and cold, which is particularly easy to cause load-bearing Ring Cracking and Local Deformation

[0004] At the same time, the working efficiency of the existing cold slag crusher is slow, and two people are required to complete the operation. One person controls the forklift unloading, and the other closes the machine door to start the switch. Moreover, the cooling water system of the existing cold slag crusher requires workers to check the water tank in real time situation and replenish water in time, which is not conducive to automatic production
