Vertical multi-cylinder or single-cylinder hydraulic briquette extruder with helical impeller feeding

Abstract

The invention relates to a vertical multi-cylinder or single-cylinder hydraulic briquette extruder with helical impeller feeding. The vertical multi-cylinder or single-cylinder hydraulic briquette extruder comprises one group or at least two groups of laterally feeding helical impeller feeding parts, one group or at least two groups of multi-cylinder or single-cylinder hydraulic molding parts which are subjected to longitudinally hydraulic molding and a PLC (Programmable Logic Controller) control part, wherein each helical impeller feeding part comprises a motor, a cycloidal pin wheel speed reducer, a coupler and an impeller shaft, the impeller shaft is arranged in a bearing pedestal and a conveying barrel, helical blades are welded on the impeller shaft, and a feeding hopper is arranged at the top of the front end of the conveying barrel; each vertical type multi-cylinder or single-cylinder hydraulic molding part comprises an oil cylinder, an extrusion piston, a briquette cavity and a briquette nose, the oil cylinder and the extrusion piston are fixedly arranged at the upper part of a rack longitudinally, the briquette cavity and the briquette nose are fixedly arranged at the lower part of the rack, and the extrusion piston is driven by the oil cylinder to move up and down in the briquette cavity; a feeding port is arranged at the upper end of the briquette cavity and is connected with the conveying barrel. Mechanical energy is converted into pressure intensity energy, made briquettes have a low water content, the yield is high, electricity consumption is reduced, and automatic control is realized.

Description

technical field [0001] The invention relates to production equipment for pulverized coal processing shaped coal, in particular to a vertical multi-cylinder or single-cylinder hydraulic coal stick machine fed by spiral impellers. Background technique [0002] Chemical plants, chemical fertilizer plants, glass products factories, gas plants, and ceramic plants use pulverized coal as briquettes for fixed-bed gas production, then crush them into powder with machines, add water after sieving, mix with binders, and process them with machines Shaped into a round rod or quincunx shape with a certain loading surface, it is called briquette (because of the lack of lump coal resources, the price is expensive and the cost is high, the gas generator basically burns briquette). This kind of briquette is produced by the principle of screw extrusion so far. It is composed of motor-pin coupling-reducer-coupling-bearing box-shaft impeller-feeding port and discharge port. The retting pulveriz...

AI Technical Summary

Problems solved by technology

The moisture content in the fuel coal is too high, the strength of the coal rod is not good and fragile, and the consumption of the gas generator is increased, that is, the phenomenon of returning material mentioned above is serious. Now most manufacturers use the coal rod from the coal rod machine to pass through another Process "drying", which also consumes energy and increases unit consumption

At present, there have been horizontal hydraulic coal rod machines, but the hydraulic cylinder is horizontal and wears a lot. The feed material adopts natural inflow, and the output of a single unit is low (actually about 2T / h). Because the feed material adopts natural inflow, it accounts for The unit time is long, the quantity cannot be achieved, and the number of labor needs to increase, so it has not existed for a long time in society
