Abstract
The utility model discloses a clearance of coal pulverizer steel ball and sieving mechanism, the novel nipple rectifier comprises a cylindrical shel, barrel two center outside all is connected with the hollow shaft, and empty spindle connection's bearing frame is fixed on the basis, and the barrel is scored one side excircle and is connected with the gear wheel, and the barrel is inside to be equipped with and to get the football shirt and put and lead ball sieve football shirt and put, get the football shirt put including get the bulb, violently manage, the baffle, get bulb two connection tube inner wall, get bulb two and be equipped with reverse score mouthful, get the bulb center and be equipped with the baffle, get the bulb and connect through the welding mode and violently manage, violently the pipe is led ball sieve football shirt through flange joint and is put, leads ball sieve football shirt and puts and is connected fixedly with coal pulverizer auger center ring, leads ball sieve football shirt and puts including leading the bulb, leads the bulb inner wall and is equipped with the water conservancy diversion strip, leads and is equipped with three row at least sieve meshes around the pipe wall of bulb exit. The beneficial effects of the utility model are that: steel ball clearance screening efficiency is high, and workman's work operation intensity is low, uses safe and reliable.
Description
Technical field
The utility model belongs to thermal power plant low speed coal mill matched auxiliaring equipment technical field, is specifically related to the cleaning of a kind of coal pulverizer steel ball and screening plant.
Background technology
Low speed coal mill is also known as ball mill, it is a kind of low-speed coal mill, rotating speed is 16 ~ 25 revs/min, and it utilizes the cylinder of low speed rotation to drive steel ball motion in cylinder, realizes the fragmentation of coal cinder and coal dust is made in grinding by steel ball to the shock of raw coal, extruding and abrasive action.Standard steel bulb diameter 30 ~ 60mm, after low speed coal mill runs a period of time, worn steel ball in coal pulverizer diminishes gradually, after steel ball size is less than 20-25mm, the effect of impact of steel ball to coal particle disappears substantially, Alloys Casting steel ball is generally after ball mill runs 2000-3000 hour, defective steel ball is rejected, as a large amount of defective steel ball is deposited in after in coal pulverizer, to produce considerable influence to exerting oneself of coal pulverizer, thus, power plant adopts and regularly stops mill cleaning steel ball, when particularly steel ball quality is poor, very short time just needs cleaning coal pulverizer steel ball.
At present, domestic thermal power plant coal pulverizer steel ball opens manhole door artificial screening and cleaning after all adopting and stopping mill, common steel ball sieve choosing method has two kinds, a kind of is after manhole in entire body is opened, and by people's porose disc to oblique below, after manually being dished out from manhole by steel ball, carries out artificial screening again.Another kind method is after opening manhole, and start barring gear, make barrel body rotation, steel ball flows out from manhole under the influence of centrifugal force.All there is potential safety hazard in traditional method, labour intensity is large, and operating environment is severe, and staff's resentment is larger.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides the cleaning of a kind of coal pulverizer steel ball and screening plant.
The technical scheme that the utility model adopts is: a kind of coal pulverizer steel ball cleaning and screening plant, comprise cylindrical shell, described cylindrical shell two is all connected with hollow shaft outside center, the bearing block that hollow shaft connects is fixed on basis, cylindrical shell goal side cylindrical is connected with gear wheel, inner barrel is provided with to get ball device and lead ball sieves ball device, described ball device of getting comprises and gets bulb, transverse tube, dividing plate, get bulb two connector drum inwall, get bulb two and be provided with reverse ball hole, get bulb center and be provided with dividing plate, get bulb and connect transverse tube by welding manner, transverse tube leads ball sieve ball device by Flange joint, lead ball sieve ball device and coal pulverizer auger center ring be connected and fixed, lead ball sieve ball device to comprise and lead bulb, lead bulb inwall and be provided with flow guide bar, lead bulb exit tube wall surrounding and be provided with at least three row's sieve apertures.
The beneficial effects of the utility model are: steel ball cleaning screening effeciency is high, and workman's labor operation intensity is low, safe and reliable.

Detailed description of the invention
In order to more clearly the technical solution of the utility model can be understood, below in conjunction with accompanying drawing, the utility model is further illustrated.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of coal pulverizer steel ball cleaning and screening plant, comprise cylindrical shell 7, cylindrical shell 7 two is all connected with hollow shaft 3 outside center, the bearing block 2 that hollow shaft 3 connects is fixed on basis 1, cylindrical shell 7 side cylindrical of scoring is connected with gear wheel 4, gear wheel 4 pinion mate, pinion is by motor reducer driven rotary, cylindrical shell 7 inside is provided with to get ball device 5 and lead ball sieves ball device 6, get ball device 5 to comprise and get bulb 54, transverse tube 53, dividing plate 52, get bulb 54 two connector drum 7 inwall, get bulb 54 two and be provided with reverse ball hole 55, opening direction is consistent with coal pulverizer rotation direction, get bulb 54 center and be provided with dividing plate 52, get bulb 54 and connect transverse tube 53 by welding manner, transverse tube 53 end connects left flange 51, lead ball sieve ball device 6 to comprise and lead bulb 63, lead bulb 63 goal end and connect right flange 61, left flange 51 is bolted with right flange 61, lead bulb 63 inwall and be provided with flow guide bar 62, lead bulb 63 exit tube wall surrounding and be provided with a few row's sieve aperture 64, lead ball sieve ball device 6 to be connected and fixed with coal pulverizer auger center ring.
During use, start coal pulverizer jiggering or be entirely rotate, get bulb 54 with leading together with bulb 63 and rotate with cylindrical shell 7, get bulb 54 open-ended go to bottom time, steel ball enters to be got in bulb 54, cylindrical shell 7 is rotated further the steel ball when getting bulb 54 and going to more than horizontal level and slips to intermediate membrane 52 place under gravity, and enter and lead in bulb 63, under the effect of flow guide bar 62, steel ball flow to outlet, through sieve ball section time, little steel ball falls into defective district from sieve aperture 64, qualified steel ball flows out from outlet, enters qualified district, completes screening process.
