Description

Technical field:

[0001] The utility model belongs to the field of coal transportation, in particular to a coal falling recovery device of a medium coal belt conveyor. Background technology:

[0002] In the coal washing production industry, various types of coal are mainly transported to different work section systems through belt conveyors. Taking medium coal as an example, medium coal is a mixture of gangue and clean coal separated from raw coal. It is a mixture of raw coal with an ash value between clean coal and gangue. The particle size of medium coal is between 13-50mm and it is often used as fuel or raw material. In the process of conveying medium coal, when the medium coal discharged from the silo falls on the receiving end of the belt conveyor, a small part of the medium coal will inevitably fall, resulting in coal scattering around the receiving end of the belt conveyor. The scattered medium coal will not only destroy the working environment after piling up, but also affect the normal operation of the belt conveyor, and operators need to be dispatched to shovel it, which increases the workload of the operators. Utility model content:

[0003] The utility model aims to provide a device for recovering fallen coal of a middle coal belt conveyor, and overcomes the shortcomings of the above-mentioned prior art, and effectively solves the existing problem of coal falling during the middle coal conveying process.

[0004] Contents of the utility model: A coal recovery device for a medium coal belt conveyor, comprising a collecting trough, which is installed just below the material receiving end of the belt conveyor, a discharge pipe is connected to the bottom wall of the collecting trough, and a material flow-aiding component is arranged on the collecting trough.

[0005] Furthermore, the angle of the collecting trough is inclined downward, the material flow-aiding component is located at the highest end of the collecting trough, and the discharge pipe is located at the lowest end of the collecting trough.

[0006] Furthermore, the material flow-aiding component includes a water supply pipe spanning the collecting tank, and a plurality of flushing branch pipes are evenly connected to the water supply pipe, and the water outlet ends of the flushing branch pipes are oriented toward the discharge pipe.

[0007] Furthermore, a duckbill nozzle is installed at the water outlet end of the flushing branch pipe.

[0008] Furthermore, a semi-enclosed baffle is installed at the top edge of the collecting trough, and the semi-enclosed baffle is located at the material receiving end of the belt conveyor.

[0009] Furthermore, a pair of hanging arms are installed on both side walls of the collecting trough, the top ends of the hanging arms are fixedly connected to the hooks by bolts, and the hooks are hung on the frame of the belt conveyor.

[0010] The beneficial effects of the utility model are as follows: the medium coal dropped by the belt conveyor can be collected through the collecting trough, and the medium coal can be transported to the centrifugal liquid pump pit through the discharge pipe, thereby avoiding the damage to the working environment caused by the falling coal, and at the same time ensuring the normal operation of the conveying equipment and reducing the work intensity of the operators.

[0015] In the figure, 1 is a collecting trough, 2 is a belt conveyor, 3 is a discharge pipe, 4 is a water supply pipe, 5 is a flushing branch pipe, 6 is a duckbill nozzle, 7 is a semi-enclosed baffle, 8 is a hanging arm, and 9 is a hook. Specific implementation method:

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings:

[0017] like Figures 1 to 4 As shown, a coal recovery device for a medium coal belt conveyor comprises a collecting trough 1, wherein the collecting trough 1 is installed just below the material receiving end of the belt conveyor 2, a discharge pipe 3 is connected to the bottom wall of the collecting trough 1, a material flow-aiding component is arranged on the collecting trough 1, the angle of the collecting trough 1 is inclined downward, the material flow-aiding component is located at the highest end of the collecting trough 1, the discharge pipe 3 is located at the lowest end of the collecting trough 1, the material flow-aiding component comprises a water supply pipe 4 spanning the collecting trough 1, a plurality of flushing branch pipes 5 are evenly connected to the water supply pipe 4, the water outlet end of the flushing branch pipe 5 is oriented toward the discharge pipe 3, and a duckbill nozzle 6 is installed at the water outlet end of the flushing branch pipe 5.

[0018] Specifically, the medium coal dropped by the belt conveyor 2 can be collected through the collecting trough 1.

[0019] During actual use, the medium coal dropped by the belt conveyor 2 will fall into the collecting trough 1 below. The collecting trough 1 set at an angle downward allows the medium coal to slide to the lower end and is transported to the centrifugal liquid pump pit through the discharge pipe 3. During this period, the flushing branch pipe 5 located at the highest end of the collecting trough 1 sprays water in a fan shape onto the bottom wall of the collecting trough 1. With the assistance of the water flow, the medium coal can enter the discharge pipe 3 faster, thereby facilitating its rapid recovery.

[0020] like Figures 1 to 4 As shown, a semi-enclosed baffle 7 is installed at the top edge of the collecting trough 1, and the semi-enclosed baffle 7 is located at the material receiving end of the belt conveyor 2. A pair of hanging arms 8 are installed on both side walls of the collecting trough 1. The top ends of the hanging arms 8 are fixedly connected to the hooks 9 by bolts, and the hooks 9 are hung on the frame of the belt conveyor 2.

[0021] Specifically, the collecting trough 1 can be quickly installed on the belt conveyor 2 through the hook 9.

[0022] In actual use, the semi-enclosed baffle 7 can expand the collection area of ​​the falling materials; the hook 9 installed at the top of the hanging arm 8 makes it easy for the collection trough 1 to be quickly hung on the frame of the belt conveyor 2. When the belt conveyor 2 needs to be repaired, the bolts are loosened to separate the hook 9 from the hanging arm 8, which makes it easy to quickly separate the collection trough 1 from the belt conveyor 2, thereby providing a maintenance space for personnel to operate.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
