Description

A kind of ball mill drawing mechanism
Technical field
The utility model belongs to the plant equipment field, relates in particular to a kind of ball mill drawing mechanism.
Background technology
Ball mill is used very general in micro mist is produced, still, for micro mist materials such as aluminium oxide, when granularity little behind micron order, the flowability of the material non-constant that becomes, even the tapering of hopper is very big, material can not flow out automatically yet.In the past, we once adopted in ball mill discharging opening bottom the taper aggregate bin were set, and installed the method for discharging spiral additional in the bottom of aggregate bin, attempted to realize through helical feed the airtight continuous discharging of ball mill, still, did not succeed.Main cause is because material can be bonded on the helical blade, makes spiral forfeiture conveying capacity.
For the bad granular material of flowability, the method that generally adopts at present is: at ball mill discharging position and the bottom confined space is set.Rotate grinding machine during discharging earlier, be put into the powder in the grinding machine in this confined space.After having gone out material, the discharge door of this confined space is opened, dug out with relying on artificial material one spade one spade that will wherein pile up with instruments such as spade, round-bottomed baskets, subsequent job such as sieve.Adopt this method, labor strength is big, and efficiency is low, and dust pollution loses greatly with flying upward, and the working site environmental sanitation is poor, can't realize the continuous automatic production of grinding machine and follow-up screening flow process.
The utility model content
The difficult problem that the utility model can't flow out from the hopper under the ball mill to mobile bad granular material automatically; A kind of simple solution has been proposed; Airtight, gravity flow, the quantitative discharging of ball mill production procedure have been realized, for condition has been created in the continuous and automatic operation of subsequent production flow process.
Above-mentioned purpose realizes through following proposal:
A kind of ball mill drawing mechanism is characterized in that said drawing mechanism comprises the grinding machine cover, and said grinding machine cover surrounds ball mill discharging position, and said grinding machine cover suspension is fixed on the ball mill top platform and the bottom is a conical bottom; Said grinding machine cover front and back panel is parallel to the ball mill axis, and left and right sides panel has circular port perpendicular to the ball mill axis on the panel of the said left and right sides, and this circular port is enclosed within on the ball mill barrel; Bottom in said conical bottom is provided with discharge barrel, on this discharge barrel, valve is installed.
According to claims 1 described ball mill drawing mechanism, it is characterized in that in conical bottom, be parallel to the base plate of conical bottom, welded and installed has one deck orifice plate, is equipped with the ventilative cloth of one deck on this orifice plate; On the base plate of said conical bottom, be provided with compressed air inlet.
According to claims 2 described ball mill drawing mechanisms, it is characterized in that, be provided with the interface tube that gathers dust on the top of said grinding machine cover.
The beneficial effect of the utility model: after ball mill adopts the drawing mechanism of the utility model, even mobile very poor micro mist material also can be realized airtight, gravity flow, quantitative discharging.Can alleviate labor strength greatly, enhance productivity, reduce dust pollution and fly upward loss, for condition has been created in the continuous and automatic operation of subsequent production flow process.
Description of drawings
Fig. 1 is the structural representation of the drawing mechanism of the utility model;
Fig. 2 is the side view of the drawing mechanism of the utility model.
The specific embodiment
Below in conjunction with attaching Fig. 1 and 2 and the specific embodiment is described further the utility model.
A kind of ball mill drawing mechanism of the utility model comprises grinding machine cover 15, and grinding machine cover 15 tops are ball mill top platform 1, and 15 suspensions of grinding machine cover are fixed on the grinding machine top platform 1, and grinding machine cover 15 bottoms are conical bottom 6.Grinding machine cover 15 is the square tubular constructions that are welded by steel plate and section bar, surrounds ball mill discharging position, forms an airtight space with ball mill top platform 1, conical bottom 6.Grinding machine cover 15 front and back panels are parallel to the ball mill axis, and left and right sides panel is perpendicular to the ball mill axis.Have circular port on the panel of the left and right sides, can be enclosed within on the ball mill barrel 3, the distance A of circular port edge and ball mill barrel 3 is not less than 10mm.
Grinding machine cover 15 bottoms and welding of conical bottom 6 usefulness or flange ways of connecting link together.The bottom of conical bottom 6 is provided with discharge barrel 9, and valve 7 is installed on the discharge barrel 9.In conical bottom 6, be parallel to the base plate of conical bottom 6, welded and installed has one deck orifice plate 5.Be welded on the position that grinding machine cover 15 bottoms are connected with conical bottom 6 around the orifice plate 5, the position, awl bottom of orifice plate 5 is welded on the discharge barrel 9.Orifice plate 5 is not less than 20mm with the distance L of the base plate of conical bottom 6.Be equipped with the ventilative cloth 4 of one deck on the orifice plate 5, ventilative cloth 4 usefulness bolts 12 are fixed on the orifice plate 5 with press strip 11, form a broach hopper of being made up of ventilative cloth 4.On the base plate of conical bottom 6, be provided with compressed air inlet 10, can feed compressed air.Like this, between ventilative cloth 4 and conical bottom 6, just form an aeration tank structure.When feeding compressed air, get into the compressed air of aeration tank, see through ventilative cloth 4, can make the material of piling up on the ventilative cloth 4 form " fluidization ".Even mobile very poor micro mist material under the effect of air-flow, also can have good flowability, under the effect of himself gravity, flow to discharge barrel 9, and the valve of on discharge barrel 9, installing 7 flows out automatically.
During discharging, open ball mill discharging opening 14 earlier, the powder in the roating sphere grinding machine then, ball mill can drop in the broach hopper of ventilative cloth 4 formations under the effect of centrifugal force and gravity.Feed compressed air from compressed air inlet 10, the material of piling up on the ventilative cloth 4 can produce " fluidization " phenomenon under the effect of air-flow, as current, under the effect of self gravitation, flows to discharge barrel 9.Open the valve 7 on the discharge barrel 9, material promptly can flow out automatically.The aperture of the valve 7 on the control discharge barrel 9 can be controlled discharging flow.
When going out to grind, can produce dust from flying.Therefore, be provided with the interface tube 2 that gathers dust, connect dust-precipitator on the top of grinding machine cover 15.Open dust-precipitator, make to form negative pressure in the grinding machine cover 15, can effectively eliminate flour dust overflow.
In order to make grinding machine cover 15 more firm, bracing frame 13 is installed on the ball mill bearing, grinding machine cover 15 is reinforced.
