Description

Technical Field

[0001] The utility model relates to the technical field of coal processing, in particular to a coal washing tank which is easy to clean. Background Art

[0002] Coal washing generally refers to the process of removing gangue or other impurities from coal. Coal washing is generally carried out by utilizing the different physical properties of coal and gangue. Most of the cleaning is done by cleaning the coal with water.

[0003] However, when the existing coal cleaning trough is put into use, after the water source has cleaned the coal, dust will fall into the interior of the working shell along with the water source. The dust will become sticky due to the water source, and some of the dust will adhere to the surface of the inner wall of the working shell. When the staff discharges the water source, the dust will remain on the inner wall of the working shell. Over time, it will cause the dust to continue to accumulate, thereby affecting the working shell. At the same time, most of the water sources are sprayed through nozzles, but the coal is moved and cleaned through a transmission network, and since the nozzles are in a stationary state, it is easy to cause incomplete coal cleaning.

The inner cavity of the support frame 2 is provided with a nozzle 4. Under the action of the conveying component 3, the water source can enter the interior of the nozzle 4. A stepping motor 5 is bolted on the side of the support frame 2 away from the conveying component 3. A rotating mechanism 6 is provided on one side of the stepping motor 5. One end of the nozzle 4 is fixedly connected to a third positive Gear 7, rotating mechanism 6 and third spur gear 7 cooperate with each other. With the cooperation of stepping motor 5 and rotating mechanism 6, the third spur gear 7 can drive the nozzle 4 to swing on one side of the support frame 2, so that the nozzle 4 can clean the coal more comprehensively, increasing the effect of the coal cleaning trough on the coal cleaning. A transmission net 8 is provided on the top of the working shell 1. The angle of the transmission net 8 is an inclined design. Under the action of the transmission net 8, the coal can be transported and the water source for cleaning the coal can be allowed to enter the bottom of the inner cavity of the working shell 1. The bottom of the surface of the working shell 1 is connected with a sewage outlet 9, which can facilitate the staff to drain the working shell 1. The water source inside the shell 1 is discharged, and the inner cavity of the sewage outlet 9 is rotatably connected with a rotating blade 10. A rotating rod 11 is fixed to the side of the rotating blade 10 close to the working shell 1. Under the action of the water source passing through the sewage outlet 9, the rotating blade 10 can drive the rotating rod 11 to rotate. A fixing plate 13 is bolted to the bottom of the inner cavity of the working shell 1. The inner cavity of the fixing plate 13 is rotatably connected to the surface of the rotating rod 11. Under the action of the fixing plate 13, the position deviation of the rotating rod 11 during work can be effectively prevented, thereby increasing the stability of the rotating rod 11, thereby increasing the stability of the washing tank, and one side of the rotating rod 11 A moving mechanism 12 is provided, and a connecting rod 14 is provided above the rotating rod 11. A rubber scraper 15 is bolted to one side of the connecting rod 14, and the other side of the rubber scraper 15 is slidably connected to the inner cavity of the working shell 1. With the cooperation of the rotating rod 11 and the moving mechanism 12, the connecting rod 14 can drive the rubber scraper 15 to move back and forth in the inner cavity of the working shell 1, so that the rubber scraper 15 can clean the surface of the inner cavity of the working shell 1, and can allow the dust on the surface of the inner cavity of the working shell 1 to be discharged through the sewage outlet 9 along with the water source, thereby facilitating the staff to clean the inner cavity of the working shell 1, thereby increasing the practicality of the washing tank.

[0023] The rotating mechanism 6 includes a first spur gear 61, the inner cavity of the first spur gear 61 is fixedly connected to the output shaft of the stepping motor 5, a second spur gear 62 is meshed on one side of the first spur gear 61, a first half gear 63 is fixedly connected to the surface of the output shaft of the stepping motor 5, a second half gear 64 is meshed on one side of the first half gear 63, the second half gear 64 and the second spur gear 62 are rotatably connected to one side of the support frame 2 through a rotating shaft, the bottom of the first half gear 63 is meshed with the top of the third spur gear 7, and the stepping motor 5 and the first spur gear are connected. With the cooperation of the wheel 61, the second spur gear 62 can drive the second half gear 64 to rotate, and the stepper motor 5 can also drive the first half gear 63 to rotate. When the first half gear 63 rotates to a position where it is not engaged with the third spur gear 7, the second half gear 64 and the third spur gear 7 engage with each other, thereby causing the third spur gear 7 to rotate in the opposite direction, thereby enabling the third spur gear 7 to drive the nozzle 4 to reciprocate in the inner cavity of the support frame 2, so that the nozzle 4 can clean the coal more comprehensively, thereby increasing the practicality of the selection and washing tank.

[0024] The moving mechanism 12 includes a bevel gear set 121, one side of which is fixedly connected to the other end of the rotating rod 11. The bevel gear set 121 is composed of two bevel gears of the same size that mesh with each other. A reciprocating threaded rod 122 is fixed to the other side of the bevel gear set 121. The surface of the reciprocating threaded rod 122 is threadedly connected to a sleeve 123. The surface of the sleeve 123 is bolted to one end of the connecting rod 14. Under the cooperation of the rotating rod 11 and the bevel gear set 121, the reciprocating threaded rod 122 can drive the connecting rod 14 to move through the sleeve 123, thereby making the connecting rod 14 The rubber scraper 15 is driven to clean the surface of the inner cavity of the working shell 1, so that the dust on the surface of the inner cavity of the working shell 1 is discharged along with the water source, which is convenient for the staff to clean the inner cavity of the working shell 1, thereby reducing the accumulation of dust on the surface of the inner cavity of the working shell 1. A bearing seat 16 is fixed to the bottom of the inner cavity of the working shell 1, and the top of the bearing seat 16 is rotatably connected to one end of the reciprocating threaded rod 122.

[0025] Working principle: First, the staff transmits the coal through the transmission net 8. When the coal moves to the bottom of the support frame 2, under the action of the conveying component 3, the water source can be sprayed through the nozzle 4. At the same time, under the cooperation of the stepping motor 5 and the first spur gear 61, the second spur gear 62 can drive the second half gear 64 to rotate at the same time, and the stepping motor 5 drives the third spur gear 7 to rotate through the first half gear 63. When the first half gear 63 rotates to a position where it is not engaged with the third spur gear 7, the second half gear 64 meshes with the third spur gear 7, causing the third spur gear 7 to rotate in the opposite direction, thereby realizing that the third spur gear 7 drives the nozzle 4 to swing back and forth on one side of the support frame 2, so that the nozzle 4 cleans the coal more comprehensively and With the cooperation of multiple belt pulleys and multiple timing belts, multiple nozzles 4 can be made to swing back and forth at the same time. When the water source for cleaning the coal falls into the inner cavity of the working shell 1 to a certain position, the staff discharges the water source through the drain outlet 9. When the water source passes through the inside of the drain outlet 9, it drives the rotating blades 10 to rotate. The rotating blades 10 drive the reciprocating threaded rod 122 to rotate through the rotating rod 11. The reciprocating threaded rod 122 drives the connecting rod 14 to move the rubber scraper 15 through the sleeve 123, so that the rubber scraper 15 can clean the surface of the inner cavity of the working shell 1, so that the dust on the surface of the inner cavity of the working shell 1 is discharged along with the water source through the drain outlet 9. Then the staff continues to clean the coal on the top of the transmission network 8.
