Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a combined closed hood dust collection system. Background Art

[0002] Bulk cement and other materials are generally transported and transferred by belt conveyors. However, due to the characteristics of the materials, a large amount of dust will be generated during the dropping and transportation, affecting the working environment. The existing technology generally sets a material guide trough on the belt conveyor for sealing and dust removal. However, the existing material guide trough has a single structure, and effective dust reduction cannot be achieved only by the damping rubber curtain at the end. Dust will still be carried out and overflowed during transportation. Utility Model Content

[0003] Technical purpose: In view of the shortcomings of the above-mentioned existing dust removal equipment, the utility model discloses a combined closed hood dust collection system which is easy to assemble and can effectively suppress dust spillage and ensure a clean working environment.

[0004] Technical solution: To achieve the above technical objectives, the utility model adopts the following technical solution:

[0005] A combined closed hood dust collection system includes a material discharge sealing hood for sealing the connection between an upstream belt conveyor and a downstream belt conveyor and a dust suppression type material guide chute arranged on the downstream belt conveyor. The dust suppression type material guide chute includes an outer shell and a dust blocking baffle arranged in the outer shell. A dust suction sealing hood is arranged on the top of the outer shell. The dust suction sealing hood is connected to a dust collector. During dust removal, a negative pressure area is formed at the connection between the dust suction sealing hood and the outer shell to absorb dust.

[0006] Preferably, the dust baffle of the utility model is fixed to the upper part of the inner wall of the outer shell, the dust baffle is arranged perpendicular to the conveying direction of the downstream belt conveyor, and a material conveying space is left between the lower part and the conveying belt of the downstream belt conveyor.

[0007] Preferably, the dust-blocking baffles of the utility model are arranged at intervals along the length direction of the outer shell, and the dust-absorbing sealing cover is located between a group of adjacent dust-blocking baffles.

[0008] Preferably, the dust collection sealing cover of the utility model adopts a trumpet-shaped structure.

[0009] Preferably, a damping dust curtain is provided at the end of the outer shell of the utility model.

[0010] Preferably, the outer shell of the utility model adopts a segmented structure, including a plurality of prefabricated shell units, and adjacent shell units are connected by bolts.

[0011] Beneficial effects: The combined closed hood dust collection system provided by the utility model has the following beneficial effects:

[0012] 1. The utility model sets a dust baffle in the outer shell to block the dust, and forms a negative pressure area through the dust suction sealing cover to absorb the dust, so as to effectively clean the dust generated by the belt conveyor and reduce overflow.

[0013] 2. The dust baffle of the utility model is arranged perpendicular to the conveying direction of the downstream belt conveyor. The dust running with the conveyor will fall onto the belt conveyor under the blocking of the dust baffle, while some lightweight fine dust will move to the end of the dust suppression type material guide trough, be blocked at the damping type dust curtain, and return to the adjacent dust baffle under the action of negative pressure, thereby reciprocating to reduce kinetic energy, and finally settle onto the belt conveyor; through the dust collection system of the utility model, dust overflow can be effectively reduced, fine dust can be recovered, and the energy consumption of the dust removal system can be reduced.

[0017] The present invention will be described more clearly and completely below by way of a preferred embodiment in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiment.

[0018] like Figure 1 The figure shows a combined enclosed hood dust collection system provided by the utility model, including a material discharge sealing hood 3 for sealing the connection between the upstream belt conveyor 1 and the downstream belt conveyor 2, and a dust suppression type material guide chute 4 arranged on the downstream belt conveyor 2, the dust suppression type material guide chute 4 includes an outer shell 5 and a dust blocking baffle 6 arranged in the outer shell 5, a dust suction sealing hood 7 is arranged on the top of the outer shell 5, and the dust suction sealing hood 7 is connected to the dust collector. When dust is removed, a negative pressure area is formed at the connection between the dust suction sealing hood 7 and the outer shell 5 to absorb dust. In order to facilitate structural assembly and adapt to the use requirements of different scenarios, the outer shell 5 of the utility model can adopt a segmented structure, including a plurality of prefabricated shell units, and adjacent shell units are connected by bolts.

[0019] The dust-proof baffle plate 6 of the utility model is fixed on the upper part of the inner wall of the outer shell 5, and the dust-proof baffle plate 6 is arranged perpendicular to the conveying direction of the downstream belt conveyor 2. A material conveying space is left between the lower part and the conveying belt of the downstream belt conveyor 2, and a damping dust-proof curtain is arranged at the end of the outer shell 5; in order to better block the dust and make it fall onto the downstream belt conveyor 2, the dust-proof baffle plates 6 of the utility model are arranged at intervals along the length direction of the outer shell 5, and the dust-absorbing sealing cover 7 is located between a group of adjacent dust-proof baffle plates 6. When dust removal is performed, the dust-absorbing sealing cover 7 is used to absorb the dust. Preferably, the dust-absorbing sealing cover 7 of the utility model adopts a trumpet-shaped structure, so that the wind speed at the junction of the dust-absorbing sealing cover 7 and the outer shell 5 is relatively low. Although negative pressure can be formed, only dust with smaller particle size is absorbed, and large particles of dust will fall onto the downstream belt conveyor 2 under the blocking of the dust-proof baffle plate 6 and the action of gravity, and move with the material.

[0020] When the utility model is in use, the unloading point of the upstream belt conveyor is wrapped by the unloading sealing cover 3, which can effectively prevent the dust from escaping and ensure the smooth unloading of the material; the material falls from the upstream belt conveyor 1 to the downstream belt conveyor 2, and the large particles of dust in the dust generated by the unloading fall on the downstream belt conveyor 2, and the fallen dust and the dust that has not been adsorbed in time run with the material at the same time, encounter the dust blocking baffle 6, are partially blocked and fall on the downstream belt conveyor 2, and at the same time, finer and lighter dust is transported with the material to the tail of the dust suppression type material guide chute 4, encounter the end damping dust blocking curtain, be blocked again, and return to the dust blocking baffle 6 under the action of the slight negative pressure inside the dust suppression type material guide chute 4. In the reciprocating motion, the kinetic energy of the dust gradually decreases and finally settles; after the dust absorbed by the dust suction sealing cover 7 is processed by the dust collector, the air discharged from the dust collector outlet is 99.6% purified air, and energy consumption can be effectively reduced.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
