Description

Wind blowing type belt return surface cleaning device

Technical Field

The utility model relates to the technical field of conveying belts, in particular to a blowing type belt return surface cleaning device.

Background

The blast furnace slag treatment drum system is used as core equipment of a blast furnace and plays a role in separating granulated water from water slag of the blast furnace. When the belt conveyer is used, high-pressure gas and high-pressure water spray nozzles wash the drum screen, the washed slag enters the return surface of the conveying belt in the drum, and the drum and the belt can be worn in the conveying process, so that the roller skin of the belt speed-changing drum is seriously corroded and worn. The blast furnace has the advantages that the blast furnace needs to be replaced when the service life is less than half a year, and the normal slag discharge of the blast furnace is influenced.

The utility model provides a blowing type belt return surface cleaning device for achieving the purpose, which comprises a conveying frame and variable speed rollers arranged at the head end and the tail end of the conveying frame, wherein the variable speed rollers are sleeved with a conveying belt, a plurality of carrier roller groups are arranged below the conveying belt by the conveying frame, a front driving roller and a rear driving roller are arranged on the conveying frame in parallel, front chain wheels are arranged at the two ends of the front driving roller, a front bracket is connected with the two front chain wheels together, a grate bar is arranged on the front bracket, and the grate bar is abutted with the return surface of the conveying belt; the two ends of the rear driving roller are provided with rear chain wheels, the two rear chain wheels are connected with a rear bracket together, a main air pipe is arranged on the rear bracket, a plurality of branch blowing pipes are uniformly distributed on the main air pipe, the main air pipe is externally connected with a compressed air source, and the front chain wheels and the rear chain wheels on the same side are in chain transmission.

As a further improvement of the above scheme, the branch blow pipe is connected with the main air pipe through threads.

As a further improvement of the scheme, the branch blowing pipe comprises a pipe body and an air nozzle, wherein the pipe body is in threaded connection with the main air pipe, and the air nozzle is arranged as a duckbill air nozzle.

As a further improvement of the above, the air nozzle is internally provided with a wedge-shaped cavity, and the cross-sectional area of the wedge-shaped cavity gradually decreases from the inside to the outside of the air nozzle.

As a further improvement of the scheme, the conveying frame is provided with a limiting rod corresponding to the rear bracket.

The beneficial effects of the utility model are as follows:

compared with the prior art, the wind blowing type belt return surface cleaning device provided by the utility model has the advantages that when the wind blowing type belt return surface cleaning device is used, the grate bars on the front support clean the return surface of the conveying belt, then the branch blowing pipes on the rear support blow compressed air to the conveying belt to purge residual small particles, under the general condition, the branch blowing pipes are obliquely arranged relative to the belt, when excessive materials on the conveying belt return surface are received, the grate bars drive the rear support to move along with the chain, so that the branch blowing pipes rotate to the vertical position from the inclined position (through the cooperation of the limiting rods and the rear support), the distance between the compressed air blown by the branch blowing pipes and the conveying belt is shortened, the acting force is increased, the residues on the return surface of the conveying belt are purged strongly, and the cleaning effect is improved. The wind blowing type belt return surface cleaning device provided by the utility model can clean the conveying belt return surface, so that the corrosion and abrasion of the belt speed changing roller skin are reduced.

Drawings

The utility model is described in further detail below with reference to the attached drawing figures, wherein:

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a schematic view of the structure of the front driving roller, the rear driving roller, and the like in another state of the present utility model.

Detailed Description

As shown in fig. 1-2, the wind blowing type belt return surface cleaning device provided by the utility model comprises a conveying frame and variable speed rollers arranged at the head and tail ends of the conveying frame, wherein a conveying belt 100 is sleeved on the variable speed rollers, a plurality of carrier roller groups are arranged below the conveying belt 100 on the conveying frame, a front driving roller 4 and a rear driving roller 5 are arranged on the conveying frame in parallel, front chain wheels 6 are arranged at two ends of the front driving roller 4, two front chain wheels 6 are connected with a front bracket 7 together, a grid section 8 is arranged on the front bracket 7, and the grid section 8 is abutted with the return surface of the conveying belt 100; the two ends of the rear driving roller 5 are provided with rear chain wheels 9, the two rear chain wheels 9 are connected with a rear bracket 10 together, the rear bracket 10 is provided with a main air pipe 1, a plurality of branch blowing pipes 2 are uniformly distributed on the main air pipe 1, the main air pipe 1 is externally connected with a compressed air source, and the front chain wheels 6 and the rear chain wheels 9 on the same side are driven by a chain 3.
