Background
During the conveying process of materials (such as raw coal), the upper-level conveying belt generally has a height difference in the conveying process towards the lower-level conveying belt, and the materials enter the material guide groove through the blanking barrel so as to enter the lower-level conveying belt for transportation. In the material transportation process, the material flow in the blanking barrel falls to drive air to enter the material guide chute, so that the internal pressure of the material guide chute is increased, material dust is sprayed out from the material outlet of the material guide chute, and the field environment pollution is caused, as shown in the attached drawing 1.
Disclosure of Invention
The utility model discloses a solve the belt conveyor transported substance in-process, the problem of dusting that the baffle box pressure increase leads to provides a device that reduces conveyer baffle box and dusts.
The utility model discloses an adopt following technical scheme to realize: the utility model provides a conveyer guide chute, includes the guide chute body, is connected with blanking barrel on the guide chute body, is connected with the return-air duct between guide chute body and the blanking barrel. The malleation that the baffle box body formed passes through the return air duct and gets into blanking barrel, at blanking barrel and the inside wind channel that forms of baffle box, reduces baffle box export air current, reduces the baffle box export and dusts.
The top of the outlet position at the front end in the guide chute body is provided with the wind-shielding curtain. Reduce the air current at the outlet of the guide chute and reduce the powder spraying at the outlet of the guide chute.
Foretell conveyer guide chute, the tail end upper portion of guide chute body is connected with pressure relief device, and pressure relief device is the tube-shape skeleton, and the outside parcel of tube-shape skeleton filters the cotton. The air current in the baffle box body can be discharged through the cylindrical framework, the filter cotton prevents dust from being discharged, the internal pressure of the baffle box is further released, the air current at the outlet of the baffle box is reduced, and the powder spraying at the outlet of the baffle box is reduced.
Foretell conveyor chute, the wind-break curtain includes the roof, and the roof is fixed at this internal top of chute, and the roof lower surface equipartition has the rubber strip curtain.
The pressure reducing device comprises two end rings, a plurality of steel bars are connected between the two end rings, and the end rings at the two ends and the steel bars connected with the end rings form a cylindrical framework.
Foretell conveyer guide chute, the filter pulp material is synthetic fiber, and thickness is 10 millimeters, wraps up two-layer on the skeleton, and the gross thickness is 20 millimeters, and two-layer filter pulp needs the staggered joint concatenation.
The utility model discloses let baffle box and blanking cylindric one-tenth closed wind channel, the partial pressure release of baffle box internal pressure to the blanking section of thick bamboo reduces the condition of dusting. The air resistance curtain at the outlet of the guide chute increases the air resistance at the outlet of the guide chute and reduces powder spraying. The pressure reducing device at the tail part of the guide chute further reduces the pressure difference between the guide chute and the environment and reduces the powder spraying. The utility model discloses greatly reduce the material in the belt conveyor transportation, because the baffle box condition of dusting that the baffle box pressure leads to greatly, the production site environment is greatly improved.

In the figure: 1-a guide chute body, 2-a charging barrel, 3-an air return pipe, 4-a wind screen, 5-a pressure reducing device, 6-a lower conveyor, 7-an upper conveyor, 8-a material conveying direction and 9-a powder spraying point.
Detailed Description
The conveyer guide chute is of a cylindrical structure and is horizontally arranged at a lower-level conveyer 6, a conveying belt of the lower-level conveyer 6 penetrates through the guide chute, the guide chute is also connected with a blanking barrel 2, and an upper port of the blanking barrel 2 is positioned at a blanking point of a higher-level conveyer 7.
In order to solve the problem of powder spraying at the outlet of the guide chute, the guide chute is improved as follows:
1) the upper part of the guide chute is provided with a hole, the hole is 1.5 meters away from the blanking barrel, the opening position is connected with the lower port of the return air pipe 3, the height of the return air pipe upper port returning to the blanking barrel is 1.5 meters away from the bottom of the blanking barrel, positive pressure formed by the guide chute continues to enter the blanking barrel through the return air pipe, an air channel is formed inside the blanking barrel and the guide chute, and air flow at the outlet of the guide chute is reduced. As shown in fig. 2.
2) The outlet of the front end of the inside of the guide chute is provided with a wind shield 4 to reduce the airflow at the outlet of the guide chute. The wind-break curtain includes the roof, and the roof is fixed at this internal top of baffle box, and the roof lower surface is arranged the equipartition in rows and is had rubber strip curtain, and rubber strip curtain lower part and conveyer belt contact, and rubber strip curtain thickness is 5 millimeters, and intensive arrangement can guarantee to flow and pass through smoothly in 1 meter within range apart from the baffle box exit. As shown in fig. 2.
