Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1 to 4, an anti-dust device for a guide chute of a high-fall unloading point includes a vertical guide cylinder 1, a horizontal guide cylinder 3, and a dust cover 6.

The vertical guide cylinder 1 is arranged along the vertical direction, and one end of the vertical guide cylinder 1 is a trapezoidal coal inlet, so that a higher-level conveyor belt can convey coal conveniently. The inside chute 2 that is provided with helical structure of vertical guide cylinder 3, chute 2 arranges along vertical direction to the lower extreme of chute 2 stretches out along 3 axis directions of horizontal guide cylinder, is convenient for carry the coal and gets into inside horizontal guide cylinder 3. The chute 2 is arranged to reduce mutual collision of coal in the coal dropping process, reduce generation of coal dust and coal slag, reduce impact and loss of the coal on the coal baffle plate 4 and the belt caused by height difference, and further limit generation of the coal slag and the coal dust.

The bottom of vertical guide cylinder 1 is connected with the one end of horizontal guide cylinder 3, and horizontal guide cylinder 3 is inside to be provided with polylith fender coal board 4, keeps off the parallel interval setting of coal board 4, and from 3 one ends of horizontal guide cylinder to the other end, keeps off the length of coal board 4 and increases progressively in proper order. The coal baffle 4 is arranged to buffer the pressure during coal unloading and has the function of pressure relief. The length of the coal blocking plate 4 is gradually increased, the buffering cross section of the coal blocking plate 4 to the coal is gradually increased, the buffering of the coal blocking plates 4 to the coal is dispersed, the buffering of the coal blocking plates 4 only depending on the front coal blocking plates 4 is avoided, and the front coal blocking plates 4 are prevented from being damaged quickly. Meanwhile, each coal baffle 4 continuously buffers and decelerates coal, reduces the generation of coal slag and coal dust, and prevents the occurrence of coal slag scattering and coal dust overflow.

The coal baffle 4 is made of polyurethane composite material, and has good wear resistance, strong shock resistance, light weight and more convenient installation and unloading.

The upper cover plate 31 of the horizontal material guiding cylinder 3 is provided with a plurality of openings, the openings correspond to the positions of the coal blocking plates 4, and the coal blocking plates 4 can be inserted into the openings; the upper cover plate 3 of the horizontal guide cylinder 3 is provided with a plurality of supporting seats 5, the upper end of the coal baffle plate 4 is provided with a supporting shaft 41, and the supporting shaft 41 can be lapped on the supporting seats 5. When coal impacts the coal baffle 4 from one end of the bottom of the vertical guide cylinder 1, the coal baffle 4 can swing left and right to buffer the impact force of the coal, so that the loss of the coal baffle 4 is reduced.

The lower bottom plate 32 of the horizontal guide cylinder 3 is provided with sieve pores 7, the openings of the sieve pores 7 sequentially increase from one end to the other end of the horizontal guide cylinder 3, when coal passes through the horizontal guide cylinder 3, coal blocks with small volume fall into the next-stage conveyor belt in advance after being buffered and decelerated by the front coal blocking plates 4, and the coal blocks with large volume rebound after contacting the lower bottom plate 32 and then fall again after being continuously buffered and decelerated by the rear coal blocking plates 4. Therefore, the coal blocks with larger volume are prevented from falling in advance when the initial kinetic energy is larger, so that the next-stage conveyor belt is prevented from being damaged by impact; meanwhile, the coal blocks fall down in times, and the conveying pressure of the next-stage conveying belt is relieved.

The bottom of the horizontal material guiding channel 3 is connected with a dust cover 6, and the dust cover 6 wraps the sieve pores 7 of the lower bottom plate 32; the coal cleaning device aims to prevent coal ash generated when coal falls from overflowing, so that cleaning and cleaning of workers are saved, and labor cost is reduced.

The dust cover 6 is made of rubber materials, has high elasticity and has the functions of buffering and shock absorption.

Of course, the above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all are in the utility model discloses a under the design, utilize the equivalent structure transform that the content of the description and the attached drawings did, or direct/indirect application all includes in other relevant technical fields the utility model discloses a protection within the scope should be received to the reason.
