Abstract
The utility model relates to a Raymond mill discharge device which comprises an air compressor, a circular pipe (9) and a transmission device. The Raymond mill unloading device is characterized in that two pneumatic butterfly valves (7) which are arranged top and bottom are arranged between a storage bin (10) positioned above each discharge port (11) and a screw conveyor (8); the circular pipe (9) connects the two pneumatic butterfly valves (7) and connects the two pneumatic butterfly valves (7) with the storage bin (10) and the screw conveyor (8). According to the Raymond mill discharge device, the on-off action of the pneumatic butterfly valves (7) is controlled by a PLC (Programmable Logic Controller). The Raymond mill discharge device disclosed by the utility model has the advantages of low equipment failure rate, high reliability and low production cost.
Description
Technical field
The utility model belongs to the discharging of flour mill to be put, especially a kind of raymond mill device for discharging.
Background technology
The main powder manufacturing apparatus of using in silicon carbide micro-powder processing is Raymond mill, and the discharge port of its air current classifying system extensively adopts 0.75KW wind stopping device to carry out discharging.Wind stopping device is generally arranged on the grader cylindrical shell bottom of raymond mill, and for collection material, its structure is comprised of the impeller of rotor with several pieces blades, housing, seal and decelerator, motor etc.Storage bin top material relies on self gravitation to fall into the space between wind stopping device blade, with the rotation of blade, discharges.
But wind stopping device, as a kind of conventional gearing, has very complicated apparatus structure, and its rotor blade adopts polyurethane sheet or rubber slab more, and housing adopts gray iron casting more.Because the hardness of silicon carbide micro-powder is very larger, its Mohs' hardness is only second to diamond, therefore in the running of Raymond mill, wind stopping device easily weares and teares and makes the sealing fast-descending of system, causes gas leakage, affect the stability of whole air flow system, equipment failure rate is very high, and after wearing and tearing, is difficult for repairing, need to be by wind stopping device integral replacing, not only increase production cost, also affected Workshop Production.
Summary of the invention
The purpose of this utility model is, a kind of raymond mill device for discharging that a kind of equipment failure rate is low, reliability is high, production cost is low is provided.
The utility model comprises: air compressor machine, pipe (9), transmission device, it is characterized in that: between the storage bin (10) of each discharge port (11) top and screw machine (8), be equipped with two Pneumatic butterfly valves (7) of configuration up and down, pipe (9) is connected two Pneumatic butterfly valves (7) and Pneumatic butterfly valve (7) with storage bin (10), screw machine (8).
As improvement, for guaranteeing air flow system sealing, two Pneumatic butterfly valves (7) are opened that for this reason and are closed, and the switch motion of Pneumatic butterfly valve (7) is preferably by PLC Controlled by Programmable Controller, and source of the gas is provided by pneumatics unit.
The utlity model has the advantage that equipment failure rate is low, reliability is high, production cost is low.
