Full-automatic exhaust coal pellet-forming machine

Abstract

The invention discloses a full-automatic exhaust coal egg-forming machine. A feeding hopper extrudes crushed coal into a through hole of a forming die, a baffle plate blocks the crushed coal without leading, when the crushed coal is moved to an upper extruding die chain and a lower extruding die chain, an upper extruding column and a lower extruding column extrude the crushed coal into egg-shaped coal by using a method of sequentially moving more towards the forming die; and the produced egg-shaped coal is pushed out of the forming die, and just falls on a conveying belt to be conveyed. The invention can be used for producing the egg-shaped coal in a pipeline way and completely exhausting air in the egg-shaped coal; the egg-shaped coal can be applied to an industrial furnace for replacing blocky coal, can be matched with the blocky coal, has the advantages of complete combustion and good combustion effect, and can not cake in the furnace to block the furnace.

Description

Technical field: [0001] The invention relates to the technical field of briquette production, in particular to a machine for molding crushed coal into egg-shaped briquettes. Background technique: [0002] When coal is used in industry, some coal furnaces use lump coal, and the coal powder must be cleaned out separately. The price of the cleaned coal powder is only about 2 / 3 of the same quality as lump coal, and it is often used to produce briquettes or snail coal as civilian use. Pulverized coal itself has a good combustion value and is not accepted by furnace types for industrial use of lump coal due to its pulverized form. [0003] In order to save the cost of coal, some coal manufacturers make the crushed coal into a spherical shape, and then take the spherical briquettes into the boiler to mix with lump coal. This kind of briquette made of crushed coal is easy to burst when it is burned in the boiler. After the burst, it will become a cake in the boiler and cause the f...

AI Technical Summary

Problems solved by technology

[0004] When the existing briquettes are produced, people mainly consider the adhesive, hoping to stick the crushed coal firmly through the adhesive, and then when they are burned in the boiler, they hope that the briquettes will not turn into cakes and block the furnace. However, in fact, it is impossible to do so.

Because people's thinking is mainly concentrated on the adhesive, the production of coal briquettes is generally done by rolling forming, the production equipment is generally relatively simple, and the gas in the briquettes is not fully discharged out of the briquettes during the production process.
