The broken duster of the thin moulded coal powdered carbon of a kind of children
Technical field
The present invention relates to a kind of coal processing machine, more particularly, is the broken duster of the thin moulded coal powdered carbon of a kind of children.
Background technology
Existing coal dust processing machine, pulverizer with former coal pulverizer is only arranged, and the coal dust that processes is sent into coal dust firing pot internal combustion, when the particle of coal just may incomplete combustion during greater than 0.1mm phenomenon, cause waste, for example, the patent No. is 200420098284.4 and the patent No. is 201020170136.4 these two patents because the structure of design causes the particle major part that processes is greater than 0.1mm, thereby causes waste.
Summary of the invention
Purpose of the present invention aims to provide and a kind ofly integrates pulverizing, carries, and efficient is high, and the thin broken duster of moulded coal powdered carbon less than the children of 0.1mm coal dust can be provided.
Technical scheme of the present invention is: the broken duster of the thin moulded coal powdered carbon of a kind of children, comprise frame, wherein, frame is provided with pulverizing chamber and fan house, be provided with passage between fan house and the pulverizing chamber, plate washer and lower baffle on passage is provided with, upper plate washer is fixed on the top of passage, lower baffle is fixed on the below of passage, and the bottom of upper plate washer is lower than the top of lower baffle, is provided with the first air inlet in pulverizing chamber, be provided with switch at the first air inlet, be provided with discharging opening at fan house, also be provided with the second air inlet at the side of fan house, be provided with switch at the second air inlet; Side in pulverizing chamber is provided with spiral propeller, is provided with loading hopper above spiral propeller, and loading hopper is corresponding with the feed end of spiral propeller, and the discharge end of spiral propeller is connected with pulverizing chamber.
Can adjust respectively by switch the openings of sizes of two air inlets, the air quantity of controlling the first air inlet and the second air inlet changes to regulate the granular size of the coal dust of discharge, the demand when satisfying different combustion requirements.By be provided with the first air inlet in pulverizing chamber, be provided with the second air inlet at fan house, two air inlets all are provided with the switch of its openings of sizes of capable of regulating, discharging opening is located at the fan house top, if the needed air quantity of discharging opening immobilizes, when the intake of the first air inlet is bigger than the intake of the second air inlet, under negative pressure promotes, the quantity that coal dust in the pulverizing chamber is discharged increases, and can discharge the thin thicker coal dust of degree of children; When the intake of little mistake second air inlet of intake of the first air inlet, under the promotion of negative pressure, the quantity that the coal dust in the pulverizing chamber is discharged reduces, and the thin degree of coal dust children of discharge is thinner.
The broken duster of the thin moulded coal powdered carbon of above-mentioned a kind of children, described pulverizing chamber is provided with rotating shaft and is arranged on rotor assembly in the rotating shaft, described rotating shaft is connected with external driver device, described rotor assembly is provided with tup and the hammerhead jib that is connected with tup, and the hammerhead jib correspondence is installed in the up and down both sides of rotor assembly.
The broken duster of the thin moulded coal powdered carbon of above-mentioned a kind of children, described blower fan comprises rotating shaft, flabellum and motor, and flabellum is arranged in the rotating shaft, and rotating shaft is by motor-driven.
Pulverizing chamber and fan house all have independent rotating shaft, can adjust respectively rotating speed to adapt to different requirements.
1) when the meticulous requirement of required coal powder size improved, the rotating speed of fan was constant, and the rotating speed of pulverizing hammering accelerates, and then coal dust is beaten often, and naturally young fineness is high; 2) when required coal dust quantity will increase, then the rotating speed of fan is improved, coal input quantity increases, and required coal dust amount increases naturally; 3) should increase when needed coal dust amount, meticulous requirement improves again, and the rotating speed that then improves simultaneously fan and hammer gets final product.
The present invention adopts above-mentioned structure, and raw coal directly enters from loading hopper, is transported to pulverizing chamber and fan house through spiral propeller, because the fan blade rotating movable property of fan house is given birth to suction function, the raw coal of being pulverized by hammering in pulverizing chamber is inhaled discharging opening; Control respectively the openings of sizes of the first air inlet and the second air inlet by switch, adjust intake, realize regulating the technical purpose of discharging the pulverized coal particle size, the demand when satisfying different combustion requirements; Simultaneously, in pulverizer, in the hammering crushing process, because the fan in the machine rotates the suction function that produces, can attract external air to enter pulverizing chamber, coal dust can fully be mixed with air in machine, improve the efficient of burning; By being provided with upper and lower baffle plate in the passage between pulverizing chamber and fan house, the bottom of upper plate washer is lower than the top of lower baffle, and this structure can stop that particle is missed in the inspiration fan house greater than the raw coal of 0.1mm.
