Detailed Description

The utility model is further described below with reference to the accompanying drawings:

the present invention is further illustrated by the following specific examples, which are not intended to limit the scope of the utility model, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.

Examples

As shown in fig. 1-3, unpowered dust device establishes dust device storehouse 4 in belt conveyor 12 top including the cover, dust device storehouse 4 includes the roof, sets up two curb plates, preceding baffle 5 and backplate 6 of roof both sides, and roof, two curb plates, preceding baffle 5 and backplate 6 enclose into the chamber of falling dust, feed inlet 1 that is linked together with the chamber of falling dust is installed on the top of roof, the air outlet 3 that is linked together with the chamber of falling dust is installed to the tail end of roof, and the exit of air outlet 3 has dustproof filter screen 11, dust fall intracavity interval is provided with a plurality of damping dust-retaining curtains 7.

In this embodiment, the middle of the top plate is provided with the air return device 2, the air return device 2 is a communicating pipe, and both ends of the air return device are communicated with the dust reduction chamber and communicate the front end and the tail end of the dust reduction chamber; the bottom of the side plate is provided with an anti-overflow apron plate 9 through a pressing combination device 8, and the anti-overflow apron plate 9 abuts against the upper surface of a belt conveyor 12; the outer wall of the side plate is provided with a connecting bracket which is arranged on a middle frame of the belt conveyor 12; the side plates are splicing plates which are spliced together through bolts, and sealing gaskets 10 are arranged at splicing seams; an avoidance notch for the belt conveyor 12 to penetrate through is formed in the bottom of the rear baffle 6, and an avoidance notch for the belt conveyor 12 and coal to penetrate through is formed in the bottom of the front baffle 5; the damping dust-blocking curtains 7 are all vertically arranged, and the adjacent damping dust-blocking curtains 7 are arranged in a staggered mode to form a circuitous flow channel.

The working principle of the utility model is as follows: the material passes through the funnel chute at belt conveyor reprint point and is connected with the feed inlet, gets into the dust device storehouse, and the material can be the S type circulation under the effect of the damping that the S type was arranged owing to the produced air current of whereabouts this moment, and circuitous with the air current through air return device simultaneously, makes the impact strength of air current reduce, and the air current consumes kinetic energy in the dust device storehouse, and air outlet department will remain the air current and discharge, and the dust can not spill over the dust device storehouse after through the dust removal filter screen. Dust and air current restriction in with the storehouse can not spill over around the baffle, and dust device both sides are passed through closing device combination and are in the same place anti-overflow skirtboard and lateral wall and the close laminating of sticky tape, and dust and air current can not spill over in the bottom in the good seal structure assurance storehouse of anti-overflow skirtboard, and the material can not spill out simultaneously. And finally, the kinetic energy consumption of the air flow and the dust generated by blanking is finished in the dust falling device, and the air flow and the dust fall on the belt conveyor and are carried away along with the materials.

To the problem that present blanking point department baffle box spills the material, this equipment is through design transformation, seals the side with original rubber slab and changes polyurethane anti-overflow skirtboard into and seals, and anti-overflow skirtboard closely laminates through compressing tightly composite set and equipment curb plate, and the skirtboard is followed down has double-deck seal structure, closely laminates with the sticky tape, guarantees that the material can not incline to spill, plays sealed effect simultaneously.

This equipment has still increaseed the abdominal cavity space and has arranged "S type" damping fender dirt curtain, and the air impact and the raise dust that produce have had bigger circulation space after the material falls, sets up the return air device at the equipment top, and the air impact that can make the material stream produce consumes kinetic energy at equipment internal recycling, finally reaches the purpose of dust fall. All sections of the equipment are connected by flanges, rubber pads are additionally arranged at the joints to ensure the sealing between the sections, front and rear baffle devices are arranged at the front and rear sections of the equipment, and the double-layer sealing matched with the anti-overflow apron plate can prevent dust from overflowing, so that the aim of cleaner production of the belt conveyor is fulfilled finally.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
