Description
Technical Field
The invention relates to a coal mine separator, in particular to a filtering device in the coal mine separator.
Background
Coal dressing, also called coal washing, is a process of sorting clean coal meeting the user quality requirements from raw coal. A common coal dressing method is to arrange sieves with meshes of various specifications from top to bottom, and collect coal mines according to the sizes of blocks, so as to meet different application requirements.
The coal mine blocks fall through the mesh screen under the action of self weight, and some problems exist. If the small pieces are squeezed by the large pieces, they may not fall down, and follow the large pieces into the wrong collecting mechanism.
In order to overcome the defect, the patent of the Chinese utility model with the publication number of CN207756494U discloses a mesh belt with a vibrator group, raw coal with different block sizes passes through a mesh belt conveying mechanism below the mesh belt through the action of the vibrator group and is sent out through a discharge port.
The vibration action of the vibrator can effectively disturb the mutual extrusion of the ore blocks, so that the smaller blocks have enough chance to fall. However, the vibrator set of the aforesaid patent not only needs to vibrate itself, but also needs to rotate along with the conveyor belt, and has a complex structure and poor stability.
Disclosure of Invention
The invention aims to improve and innovate the defects and problems in the prior art and provides a coal mine separator which is simple in structure, stable and reliable.
The technical scheme includes that the coal mine separator comprises a rack and a separating mechanism arranged in the rack, wherein the separating mechanism comprises a first screening belt and a second screening belt which are distributed up and down, a feed inlet is formed in the top of the rack, one end of the first screening belt is located below the feed inlet, the other end of the first screening belt is located above the second screening belt, a first feeding belt and a second feeding belt are respectively arranged below the first screening belt and the second screening belt, one ends of the first feeding belt and the second feeding belt extend out of the rack, a first discharge port and a third discharge port are respectively arranged at the position of the rack, the first discharge port and the third discharge port are located on two opposite sides of the rack, one end of the second screening belt extends out of the rack, and the second discharge port is arranged at the position of the rack;
the first screening belt or the second screening belt comprises a belt, a plurality of leakage boxes are arranged along the belt, the chain is connected with the belt and arranged at the edge of the belt, the belt is tensioned through a driven wheel, a driving wheel is arranged at the bottom of the chain, a tooth is arranged on the outer circumference of the driving wheel and is matched with a gap on the chain, the driving wheel is connected with a motor, an inclined plate is arranged between the upper layer and the lower layer of the belt, and the lower end of the inclined plate is located above the first feeding belt or the second feeding belt.
In one embodiment, a plurality of water nozzles are arranged at the top of the frame, and the water spraying direction of the water nozzles faces downwards.
The invention has the advantages and beneficial effects that: the screening belt is driven by the driving wheel with only one tooth, when the driving wheel rotates, the tooth can drive the belt and the leakage box to accelerate suddenly at intervals, so that a vibration effect is achieved, the primary function of driving the screening belt is achieved, and meanwhile, the vibration device which is independently configured for the leakage box is reduced, so that the structure is simpler, and the screening belt is more stable and reliable.

Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "disposed" on another element, it can be directly disposed or attached to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Example 1
As shown in fig. 1-3, a coal mine separator comprises a frame 1 and a separation mechanism arranged in the frame 1, wherein the separation mechanism comprises a first screening belt 2 and a second screening belt 3 which are distributed up and down, a feed inlet 4 is arranged at the top of the frame 1, one end of the first screening belt 2 is positioned below the feed inlet 4, the other end of the first screening belt is positioned above the second screening belt 3, a first feeding belt 5 and a second feeding belt 6 are respectively arranged below the first screening belt 2 and the second screening belt 3, one ends of the first feeding belt 5 and the second feeding belt 6 extend out of the frame 1, a first discharge port 7 and a third discharge port 8 are respectively arranged at the position of the frame 1, the first discharge port 7 and the third discharge port 8 are positioned at two opposite sides of the frame 1, one end of the second screening belt 3 extends out of the frame 1, and the frame 1 is provided with a second discharge port 9 at the position;
the first screening belt 2 or the second screening belt 3 comprises a belt 10, a plurality of leakage boxes 11 arranged along the belt 10, a chain 12 connected with the belt 10 and arranged at the edge of the belt 10, the belt 10 is tensioned through a driven wheel 13, a driving wheel 14 is arranged at the bottom of the chain 12, a tooth 15 is arranged on the outer circumference of the driving wheel 14, the tooth 15 is matched with a gap on the chain 12, the driving wheel 14 is connected with a motor, an inclined plate 16 is arranged between the upper layer and the lower layer of the belt 10, and the lower end of the inclined plate 16 is positioned above the first feeding belt 5 or the second feeding belt 6.
