Material crusher for pot type furnace

Abstract

The invention relates to material equipment for production of electrolytic aluminum pre-baked anodes, and in particular relates to a material crusher for a pot type furnace, and the material crusher is equipment for calcining petroleum coke and crushing calcined material. The material crusher comprises a driving device, a pull rod, a guiding device, ratchet mechanisms and crushing pots, and the concrete structure is as follows: the output end of the driving device is connected with the pull rod, the driving device outputs power to move the pull rod, the pull rod is inserted in the guiding device, the pull rod do horizontal reciprocating linear motion by the guiding device, the pull rod and a connecting rod are hinged by a No.1 connecting shaft; each connecting shaft is connected with the ratchet mechanism, each ratchet mechanism is connected with the crushing pot, and each ratchet mechanism drives a crushing pot to crush a material. The advantages of the material crusher are that, when the pull rod moves toward one side, only half of the crushing pots crush, the motor power is reduced, two catch pawls are correspondingly arranged on each ratchet, a force couple is formed by the thrust, a cooling tank may not be damaged, and damage of an impeller can be avoided by use of the connecting head shaft.

Description

technical field [0001] The invention relates to raw material equipment for producing electrolytic aluminum prebaked anodes, in particular to a material crusher for a pot furnace, which is a device for calcining petroleum coke and crushing the calcined materials by using the pot furnace. Background technique [0002] The quality of the prepared anode material produced by the tank furnace is higher than that produced by the rotary kiln, and the investment of the tank furnace is low, and the operation cost is low, so it is widely used at present. The tank furnace is a furnace that is heated indirectly with fuel from the outside of the tank furnace based on the principle of isolating the air for heat treatment. It is suitable for carbon plants that require high material purity. During the calcination process, the raw materials can stay in the furnace from the furnace to the completion of calcination. Control, by adjusting the discharge time and discharge volume, to ensure unifor...

AI Technical Summary

Problems solved by technology

Since the upper part of the crusher is connected to the cooling tank, the thrust of the pawl is transmitted to the cooling tank through the crusher, and even the cooling tank is opened, which affects the cooling effect and affects the product quality.

In addition, the crushing teeth of the impeller are sometimes damaged due to the material
