Abstract
The present invention relates to a high-efficiency impact mill, including machine body, main shaft mounted on the bearing seats at both sides of machine body, a rotor and a striking hammer are fixed on the main shaft, and between the rotor and machine body, a low-speed rotated grate plate device is set up, and a pulverizing cavity is formed between the rotor and the grate plate device, and the material is impacted and beated back in the pulverizing cavity so as to implement pulverization, so that the qualified material can be timely discharged, and the unqualified material is fallen into the bottom portion of the cylinder body, and lifted again, and this process is cyclically repeated until the material reaches the qualified fineness, and then it is discharged from cavity. Said invented pulverizing device is high in effeciency, low in energy consumption, simple in structure, and convenient in maintenance.
Description
The present invention relates to a kind of reducing mechanism, a kind of high-efficiency impact mill of more specifically saying so.
The present hammer mill that uses, after material enters and pulverizes cavity, be subjected to the strike of the tup of high speed rotary, with a series of pulverizations such as counterpunch board counterattacks, qualified material is discharged from the comb hole, the material lagging of fully pulverizing is not on grate plate, and these materials are subjected to the milling effect of tup, discharge cavity after reaching qualified fineness from the comb hole.The defective that this disintegrating machine exists is: the material of fully pulverizing can not realized recirculation in cavity, the milling effect that can only be trapped on the grate plate by tup realizes pulverizing, thereby the wearing and tearing and the consumption of tup and grate plate have been aggravated, simultaneously material in cavity in the crushing process qualified fines can not in time discharge, must concentrate on the grate plate and discharge by the comb hole, crush efficiency is low, energy consumption and high material consumption.And the grinding machine that uses at present, its work major part is when leaning on the grinding machine revolution, material and abrasive body mix, under the effect of the frictional force that centrifugal force and cylinder inboard wall produce, be brought to certain height, the material of bottom is impacted in free-falling under the gravity effect, the abrasive body that falls, material towards broken.The defective of its existence is: abrasive body is low by free-falling impact comminution material efficient, and energy consumption height, and equipment heaviness, metal wastage are also very big.
The purpose of this invention is to provide a kind of material that can make and realize in the crushing process moving in circles in cavity, qualified fines can in time be discharged, and energy consumption is low, consume little high-efficiency impact mill.
Purpose of the present invention can realize in the following manner: a kind of high-efficiency impact mill, include horizontal arrangement body, be placed in main shaft in the body, be fixed on the rotor on the main shaft and be placed in epitrochanterian peening hammer by bearing block, be fixed with liner plate on the inwall of body, one side of body is fixed with feed hopper, downside is fixed with hopper, one end of main shaft is fixed with belt pulley, the other end of main shaft is provided with hollow shaft, be provided with bearing between hollow shaft and main shaft, stretch out the hollow shaft in the body outside and settle by bearing block; On the main shaft in rotor left side, be mounted with axle sleeve, between rotor, be provided with an energy with hollow shaft low speed rotation and the grate plate device that fixes with axle sleeve and hollow shaft at body by bearing.Described grate plate device includes the shell flange that is separately fixed on axle sleeve and the hollow shaft, is fixed with grate plate on the outer rim of shell flange.
The present invention compared with prior art has following advantage: at first material is in crushing process, and qualified fines can in time be discharged, and avoids crushing phenomenon, and underproof material still is trapped in to be pulverized in the cavity, thereby has guaranteed the discharging fineness; Secondly, be trapped in the defective material of pulverizing in the cavity, fall, realized the crushing process that material moves in circles in cavity by the rotating grate plate drive of low speed and after rising to certain altitude; The 3rd, this reducing mechanism efficient height, energy consumption is low, consumes for a short time, and simple in structure, uses easy to maintenance.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is right views of the present invention.
With reference to the accompanying drawings the present invention being done further ocean states: with reference to the accompanying drawings shown in 1,2: a kind of high-efficiency impact mill, include horizontal arrangement body 2, be placed in main shaft 7 in the body 2, be fixed on the rotor 13 of main shaft 7 and be placed in peening hammer 15 on the rotor 13 by bearing block 5, the described peening hammer 15 that is fixed on the rotor 13 is " L " type, its inboard is provided with trimmer 17, and fixing with pressing plate 16.Be fixed with liner plate 9 on the inwall of body 2, one side of body 2 is fixed with feed hopper 10, downside is fixed with hopper 1, one end of main shaft 7 is fixed with belt pulley 6, the other end of main shaft 7 is provided with hollow shaft 12,7 on hollow shaft 12 and main shaft are provided with bearing, stretch out the hollow shaft 12 in body 12 outsides and settle by bearing block 11; On the main shaft 7 in rotor 13 left sides, be mounted with axle sleeve 8, between rotor 13, be provided with an energy with hollow shaft 12 low speed rotation and the grate plate device that fixes with axle sleeve 8 and hollow shaft 12 at body 2 by bearing.Described grate plate device includes the shell flange 4 that is separately fixed on axle sleeve 8 and the hollow shaft 2, is fixed with grate plate 18 on the outer rim of shell flange 4.Described grate plate 18 is made up of some blocks of circular-arc plates with holes.
Operation principle: material is entered by feed hopper and pulverizes in the cavity, be subjected to the effect of the rotating grate plate device of low speed, be thus lifted to the certain height free-falling, drop to and catch a packet on the peening hammer of high speed rotary and pulverize, and the material after hitting obtains huge kinetic energy and is subjected to counterattack and material once more clashes into mutually and pulverize on the grate plate of grate plate device, qualified fines is in time discharged, and defective material is fallen the grate plate bottom and is raised once more.This crushing process moves in circles, and discharges from hopper until reaching qualified fineness.
