Abstract
The invention relates to a feeding device for a ball mill, in particular to a feeding device for a wet ball mill, and belongs to the field of mining mechanical equipment. The feeding device comprises a feeding pipe connected with a hollow shaft, wherein a feeding screw is arranged in the feeding pipe; a blanking chute is inserted into the feeding pipe; the end part of the feeding pipe is connected with a sealing flange; a first holding groove and a second holding groove are formed in sequence along the axial direction, which is opposite to a feeding direction, of the sealing flange; a rubber sealing ring arranged in the second holding groove is arranged between the sealing flange and the feeding pipe; an annular stepped water spray seat is arranged on the feeding pipe; the head part of the water spray seat is inserted into the first holding groove, and a water outlet hole is formed in the side face, which faces the feeding direction, of the head part; the tail of the water spray seat is connected with a water inlet pipe. By adopting the feeding device, the problem of sealing between the blanking chute and a feeder is solved, a good sealing effect is achieved, outward splashing of slurry is avoided, convenience is brought to maintenance, and the labor intensity is lowered.
Description
Technical field
The present invention relates to a kind of feeding device of ball mill, be specifically related to a kind of wet ball mill feed device, belong to mine equipment apparatus field.
Background technology
Wet ball mill is after material is broken, then the key equipment of pulverizing.It is widely used in cement, silicate product, and the production industries such as refractory material, chemical fertilizer, black and non-ferrous metal ore and glass ceramics, carry out grinding to various ores and other grindability material.Conventional feeding of ball mill mode is divided into three kinds of spiral chargings, bucket wheel charging, elephant trunk charging, and wherein, elephant trunk charging is that material enters the taper feeder that is positioned at wet ball mill hollow axle journal through elephant trunk, along the barrel of rotation, slips in ball mill voluntarily.Because there is gap the junction between emission of baiting chute and feeder, during charging, always there is ore pulp by spilling in gap, cause surrounding enviroment to pollute, the problems such as long-pending ore deposit cleaning difficulty.
Summary of the invention
According to above the deficiencies in the prior art, technical problem to be solved by this invention is: a kind of wet ball mill feed device is provided, solves the sealing problem between emission of baiting chute and feeder, good sealing effect, avoid ore pulp to spatter outward, easy to maintenance, reduce labour intensity.
Wet ball mill feed device of the present invention, comprise the feed pipe being connected with quill shaft, in feed pipe, be provided with feed auger, emission of baiting chute inserts in feed pipe, feed pipe end connects a sealing flange, sealing flange is along contrary with charging first storage tank that axially sets gradually, the second storage tank, between sealing flange and feed pipe, be provided with the rubber seal being contained in the second storage tank, feed pipe is provided with the stepped sprinkling seat of annular, sprinkling seat head inserts in the first storage tank and head is provided with apopore towards the side of feedstock direction, sprinkling seat afterbody connects water inlet pipe.
By sprinkling seat, to feedstock direction, spray water, the ore pulp oppositely sputtering is kept off down by current, because sprinkling seat head inserts in the first storage tank, therefore ore pulp is intercepted at sprinkling seat feed side, meanwhile, for wet ball mill, the water of sprinkling seat ejection can be used for moisturizing.Rubber seal encloses second sealing function, has greatly improved sealing effectiveness.The sealing flange increasing is installed and convenient disassembly, is convenient to processing, and easy and emission of baiting chute assembles.
The second described storage tank and the sealing flange between feed pipe end are provided with feed back spiral, its rotation direction is consistent with feedstock direction, feed back spiral is delivered to the ore pulp and the water that are kept off back in feed pipe, increases the difficulty that ore pulp outwards splashes simultaneously, the auxiliary sealing effectiveness that increases.
Between described sealing flange and feed pipe, be provided with sealing gasket, sealing flange rotates in company with feed pipe, therefore adopts sealing gasket well to seal.
Described sealing flange by bolted at feed pipe place.
Described sprinkling seat and the second storage tank gap are 5～10mm, and gap is difficult for excessive.
Ore pulp is in emission of baiting chute enters feed pipe time, due to factors such as impact, collisions, the phenomenon that more or less there will be ore pulp to spatter outward, the ore pulp spattering outward partly drops in feed back spiral, under the conveying effect of feed back spiral, enter feed pipe, when remainder arrives sprinkling seat, under the water impact effect of sprinkling seat, again in feed auger is returned to feed pipe.Rubber seal is carried out last sealing, avoids part current to flow out, and has reached best sealing effectiveness.
Compared with prior art, the beneficial effect that the present invention has is:
This wet ball mill feed device, by sealing flange is set, has solved the sealing problem between emission of baiting chute and feeder, and good sealing effect avoids ore pulp to spatter outward, easy to maintenance, reduces labour intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, emission of baiting chute; 2, sealing flange; 3, rubber seal; 4, sprinkling seat; 5, sealing gasket; 6, feed pipe; 7, quill shaft; 8, feed auger; 9, feed back spiral; 10, apopore; 11, the first storage tank; 12, the second storage tank; 13, water inlet pipe.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described further.
As shown in Figure 1, this wet ball mill feed device, comprise the feed pipe 6 being connected with quill shaft 7, in feed pipe 6, be provided with feed auger 8, emission of baiting chute 1 inserts in feed pipe 6, and feed pipe 6 ends connect a sealing flange 2, sealing flange 2 by bolted at feed pipe 6 places, between sealing flange 2 and feed pipe 6, be provided with sealing gasket 5, sealing flange 2, in company with feed pipe 6 rotations, therefore adopts sealing gasket 5 well to seal.Sealing flange 2 is along contrary with charging first storage tank 11 that axially sets gradually, the second storage tank 12, between sealing flange 2 and feed pipe 6, be provided with the rubber seal 3 being contained in the second storage tank 12, feed pipe 6 is provided with the stepped sprinkling seat 4 of annular, sprinkling seat 4 heads insert in the first storage tank 11 and head is provided with apopore 10 towards the side of feedstock direction, sprinkling seat 4 and the second storage tank 12 gaps are 5～10mm, under the ore pulp splashing being kept off to feedstock direction water spray, play certain moisturizing effects simultaneously, sprinkling seat 4 afterbodys connect water inlet pipe 13, by water inlet pipe, carry out moisturizing.Sealing flange 2 between the second storage tank 12 and feed pipe 6 ends is provided with feed back spiral 9, its rotation direction is consistent with feedstock direction, feed back spiral 9 is delivered to the ore pulp and the water that are kept off back in feed pipe 6, increases the difficulty that ore pulp outwards splashes simultaneously, the auxiliary sealing effectiveness that increases.
Operation principle:
Ore pulp is entering feed pipe 6 when interior through emission of baiting chute 1, due to factors such as impact, collisions, the phenomenon that more or less there will be ore pulp to spatter outward, the ore pulp spattering outward partly drops in feed back spiral 9, under the conveying effect of feed back spiral 9, enter feed pipe 6, when remainder arrives sprinkling seat 4, under the water impact effect of sprinkling seat 4, again in feed auger 9 is returned to feed pipe 6.Rubber seal 3 is carried out last sealing, avoids part current to flow out, and has reached best sealing effectiveness.
