Energy-saving type crushing machine of discharging pipeline of cement bunker

Abstract

The invention discloses an energy-saving type crushing machine of a discharging pipeline of a cement bunker. The crushing machine is mounted at a discharging opening of the cement bunker and comprisesa screen plate covering the upper part of the discharging opening and a crushing mechanism covering the lower part of the discharging opening. Multiple screen holes allowing cement which is not hardened to pass are evenly distributed in the screen plate, and when hardened cement blocks exist in discharged materials of the cement bunker, the lower end surface of the screen plate is connected withone end surface of the crushing mechanism; and when the hardened cement blocks do not exist in the discharged materials of the cement bunker, the screen plate is collected by the aid of an arc-shapedgroove, the discharging opening is opened, cement materials are directly guided out of the discharging pipeline of the cement bunker without passing the crushing machine, and the crushing mechanism can be stopped at this moment. Multiple crushing knife wheels which are driven by power to rotate and are used for crushing the hardened cement blocks are distributed on the crushing mechanism, the hardened cement blocks which are not screened out by the screen plate slide to the crushing mechanism below under the action of dead weight and are guided out of the cement bunker after being crushed by the crushing mechanism. The crushing machine has the advantages that the total crushing amount of the cement materials at the discharging opening is reduced, meanwhile, when the hardened cement blocksdo not exist in the discharged materials of the cement bunker, the crushing mechanism can be stopped, and the power consumption can be reduced substantially.

Description

technical field [0001] The invention relates to the technical field of cement industry machinery and equipment, in particular to an energy-saving cement silo discharge pipe crusher. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material, which can be mixed with water to form a slurry, which can be hardened in the air or better hardened in water, and can firmly bond sand, stone and other materials together. One of the important building materials. Cement plants generally store the produced cement in the cement warehouse. During this process, due to water leakage in the cement warehouse, climate influence, temperature difference between inside and outside the warehouse, etc., the cement in the warehouse will have different degrees of cement hardening and cement aggregation. Disposal of these agglomerates leaves the warehouse with the unset cement, thereby reducing the quality of the cement product. [0003] In the prior art, a crusher for the ...

Problems solved by technology

Cement plants generally store the produced cement in the cement warehouse. During this process, due to water leakage in the cement warehouse, climate influence, temperature difference between inside and outside the warehouse, etc., the cement in the warehouse will have different degrees of cement hardening and cement aggregation. Disposal of these agglomerates will leave the warehouse with unset cement, thereby reducing the quality of the cement product

[0003] In the prior art, a crusher for the discharge port is used to solve the problem of cement agglomeration, but there are deficiencies in the crusher of the prior art. First, the existing crushing method is not good for crushing the cement block. Second, when the cement silo is discharging, since the cement crusher is installed at the discharge port, the crusher must be turned on all the time, and the hardened and unbounded materials are broken together, which wastes electric energy
