Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to a system and method for efficiently collecting and conveying particulate materials by hydraulic remote means. Background Art

[0002] In mining operations, solid materials, especially solid materials with small particle size and good fluidity (for example, coal mines), are currently often transported through conveying equipment such as belt conveyors, augers and high-pressure airflows. However, this type of traditional conveying equipment has a complex structure, poor operational flexibility and poor production efficiency, and low conveying efficiency. At the same time, during the transportation process, solid materials may scatter, dust may be generated, and friction resistance and friction loss may occur between the materials and the conveying equipment. This not only causes serious material loss and environmental pollution, but also leads to relatively high energy consumption in material conveying operations and relatively high maintenance costs for the conveying system.

[0003] To address this problem, the existing technology usually uses high-pressure water flow to transport coal particles over long distances. However, the existing high-pressure water flow transmission system cannot control the content of coal slime slurry in real time. Material deposition is prone to occur during the transportation process, resulting in blockage of the transportation system and a low comprehensive recycling rate of water resources used for solid material transportation. In addition, water resources are seriously wasted and cannot be recycled.

[0004] In addition, hydraulic punching operation is an important part of gas extraction work. In order to further ensure the gas control and punching effect, it is currently required that each extraction drilling rig is equipped with hydraulic punching equipment. A large amount of mixture of coal and water is discharged into the construction tunnel along the drill pipe through the extraction borehole, and the coal slime is manually loaded onto a scraper conveyor or belt conveyor for transportation.

[0005] 1. A large amount of coal sludge water accumulates on site, causing the site to be dirty and messy, which does not meet the requirements of modern civilized mines;

[0006] 2. A large amount of coal sludge aggravated the siltation of the drainage pump pit at the construction site, posing a threat to the water supply and drainage system;

[0007] 3. Hydraulic punching operations and coal slime transportation operations cannot be carried out at the same time.

[0008] 4. The punching coal metering method is not advanced enough and the metering error is large.

[0009] 5. Coal slime processing and transportation are very difficult and the labor intensity is high.

[0010] At present, when conveying solid materials, especially solid materials with small particle size and good fluidity, they are often conveyed by conveying equipment such as belt conveyors, augers and high-pressure airflow. However, this type of traditional conveying equipment has a complex structure, poor operation flexibility and poor production efficiency, and low conveying efficiency. At the same time, during the conveying process, solid materials may scatter, cause dust, and cause friction resistance and friction loss between the materials and the conveying equipment. While causing serious material loss and environmental pollution, it also leads to high energy consumption in material conveying operations and relatively high maintenance costs of the conveying system.

[0103] A working method of a slurry storage box in a high-efficiency hydraulic remote collection and transportation system for granular materials:

[0104] 1) First, the coal slime is input into the input pipe 2 from the feed pipe 4, and at the same time, the staff starts the motor 7 through the controller. When the motor 7 is working, the coal slime can be thrown out from the discharge port on the input pipe 2, and then the material will be divided by the dividing plate 13. Under the influence of gravity, the material will then enter the bottom of the discharge plate 11.

[0105] 2) The water source is transported to the treatment cylinder 1 through the first pipe 18. When the input pipe 2 rotates, the stirring rod 15 can be rotated, and the turbidity sensor 17 can detect the mixing degree of the coal slime and the water source.

[0106] 3) With the assistance of the external first delivery pump and the second pipeline 19, the material in the treatment cylinder can be input into the filter press, and the filter press can separate the coal slime and water. The water source can be input into the third pipeline 22 with the assistance of the second delivery pump, and then the water source is discharged through the discharge hole 20.

[0107] 4) When the water source contacts the filter plate 24, the water source can be filtered, and the filtered water source can enter the first pipeline 18 with the assistance of the fifth pipeline 29 and the third delivery pump;

[0108] 5) The external water source can be delivered to the fourth pipe 27 through the fourth delivery pump. With the assistance of the diversion pipe 25 and the cleaning pipe 28, the filter plate 24 can be cleaned. At the same time, with the assistance of the discharge pipe 30, the impurities on the filter plate 24 can be discharged.

[0109] In the present invention, the controller starts the motor 7. When the motor 7 is working, the shaft 8 can be rotated. When the shaft 8 rotates, the first gear 9 can be rotated accordingly. At the same time, since the first gear 9 is meshed with the second gear 10, the input pipe 2 can be rotated accordingly.

[0110] Since a bearing is provided between the input pipe 2 and the feed pipe 4, the input pipe 2 can rotate normally, so that the coal slime can enter the input pipe 2. Under the action of centrifugal force, the coal slime can be thrown out from the discharge port 5. When the coal slime is thrown out, the coal slime can contact with the dividing plate 13. At the same time, with the assistance of the discharge plate, the coal slime can be crushed, and further the coal slime can be made to fall on the baffle 6. At the same time, the external water source can be transported to the processing cylinder 1 through the first pipe 18. When the input pipe 2 rotates, the rotating rod 14 can be rotated.

[0111] When the rotating rod 14 rotates, the stirring rod 15 can rotate accordingly, and the liquid level sensor 16 can prevent the occurrence of excessive water filling. At the same time, the turbidity sensor 17 can detect the mixing of coal slime and water flow. When the mud is mixed, with the assistance of the second pipe 19, the mud can be transported to the filter press, and the filter press can separate the mud into mud cake and water. At the same time, the water can enter the connecting ring 21 through the third pipe 22.

[0112] With the assistance of the sealed bearing, water can enter the rotating rod 14. As the rotating rod 14 rotates, the water can pass through the filter plate 24 with the assistance of the discharge hole 20, so that the water can be filtered. After that, the treated water can be re-transported to the first pipe 18 with the assistance of the fifth pipe, so that the water can be reused.

[0113] At the same time, the staff can pump the external water source into the fourth pipe 27, so that the water source can enter the diversion pipe 25, so that the cleaning pipe 28 can spray out the water source, and the nozzle on the cleaning pipe 28 is inclined, so that the impurities on the filter plate 24 can be cleaned, which further facilitates the cleaning work of the staff and indirectly improves the work efficiency of the staff.

[0114] Technical effects and advantages of the present invention:

[0115] In the device, the controller starts the motor. When the motor is working, the shaft can rotate, so that the input pipe can rotate accordingly, so that the coal slime can enter the input pipe. Under the action of centrifugal force, the coal slime can be thrown out from the discharge port. At the same time, with the assistance of the discharge plate, the coal slime can be crushed. At the same time, the external water source can be transported to the processing cylinder through the first pipeline. When the input pipe rotates, the rotating rod can rotate, and the stirring rod can be further rotated accordingly, so that the coal slime can be fully crushed and stirred, so that the slurry formation effect is better. At the same time, a motor drive is used to further save energy and indirectly improve the resource utilization rate of the device.

[0116] The liquid level sensor can prevent the occurrence of excessive water filling, and the turbidity sensor can detect the mixing of coal slime and water flow. After the mud is mixed, it can be transported to the filter press with the assistance of the second pipe. The filter press can separate the mud into mud cake and water, so that the coal slime can be processed. At the same time, during the processing, the coal slime will not fall to the outside and is in a closed environment, thereby avoiding the leakage of dust, further avoiding damage to the device, and indirectly extending the service life of the device.

[0117] The separated water source can pass through the filter plate, so that the water source can be filtered and processed. After that, the processed water source can be re-transported to the first pipeline with the assistance of the fifth pipeline, so that the water source can be reused, thereby improving the utilization rate of the water source, saving water, and further avoiding the waste of water.

[0118] The high-efficiency hydraulic remote collection and transportation system and method of particulate materials of the present invention obtains the turbidity and liquid level of the coal slurry in the slurry storage box in real time, and comprehensively judges whether the coal slurry meets the standard through the control value, and respectively sets corresponding treatment measures for different states of the coal slurry. Through the comprehensive control of the pulping machine, the water replenishment valve and the one-way valve, it is ensured that the coal slurry in the conveying pipeline meets the pipeline transportation standard, and the occurrence of the transportation system blockage caused by material deposition is avoided. After the coal slurry is transported, the slurry storage box and the pipeline are flushed through the cleaning valve to avoid the occurrence of pipeline blockage.

[0119] The present invention recycles the filtered water after over-filtering of the filter press by arranging a first loop formed by a return valve and a water supply valve, thereby improving resource utilization.

[0120] The preferred embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
