Description

Technical Field

[0001] The utility model relates to the technical field of coal block cleaning, in particular to a silt treatment device for coal block cleaning. Background Technique

[0002] Coal washing is to separate raw coal with different components and specific gravities into different grades through the impact of water flow, remove dust and waste rock, and reduce the ash content and sulfur content. However, since coal blocks are mined underground, there will be soil or sludge on the surface. Before the cleaning process, the silt on the surface of the coal blocks needs to be cleaned up. Usually, people dig out the coal blocks and use a water pipe to clean the silt on the coal blocks, which is time-consuming and laborious. Therefore, we need a device to clean the silt on the surface of the coal blocks.

[0003] Chinese Patent No. 201921976979.0 discloses a coal block cleaning device for a mine, including a cleaning device body.

[0024] A second rotating shaft 604 is fixedly connected to the left side surface of the U-shaped connecting plate 603, the left end of the second rotating shaft 604 is rotationally connected to the U-shaped main frame 1, and the output end of the second motor 605 is installed with a third rotating shaft 606.

[0025] The third rotating shaft 606 is rotationally connected to the inside of the cleaning chamber 5, a cleaning frame 607 is fixedly connected to the outer surface of the third rotating shaft 606, a group of first cleaning brushes 608 are fixedly connected to the inner side of the cleaning frame 607, and a group of second cleaning brushes 609 are fixedly connected to the outer surface of the cleaning frame 607.

[0026] The discharge mechanism 7 includes a first strip-shaped square tube 701 fixedly connected to the left side surface of the cleaning chamber 5, a third motor 702 is installed on the outer surface of the first strip-shaped square tube 701, the output end of the third motor 702 is installed with a lead screw 703, the lead screw 703 is rotationally connected to the inside of the first strip-shaped square tube 701, a first slider 704 is threadedly connected to the outer surface of the lead screw 703, the first slider 704 is slidably connected to the inner wall of the first strip-shaped square tube 701, and a first connecting block 705 is fixedly connected to the upper surface of the first slider 704.

[0027] On the right side surface of the first connection block 705, there is a fixedly connected discharge baffle 706. On the outer surface of the discharge baffle 706, there is a slidably connected discharge shell 707. The discharge shell 707 is fixedly connected to the outer surface of the cleaning bin 5. On the right side surface of the discharge shell 707, there is a fixedly connected second connection block 708. On the bottom surface of the second connection block 708, there is a fixedly connected second slider 709. Inside the second slider 709, there is a slidably connected slider 710.

The second slider 709 is slidably connected to the inner wall of the second strip-shaped square tube 711.

[0028] By opening the discharge baffle 706, coal blocks can be added into the cleaning bin 5.

[0029] By starting the first motor 601 and the second motor 605, the first motor 601 drives the first rotating shaft 602 to rotate. Since the first rotating shaft 602 is fixedly connected to the cleaning bin 5, the cleaning bin 5 will rotate accordingly. At the same time, the second motor 605 drives the third rotating shaft 606 to rotate inside the cleaning bin 5 in the opposite direction to the first rotating shaft 602. The cleaning rack 607 fixed on the third rotating shaft 606 rotates accordingly.

[0033] Working principle: When this device is in use, first start the first motor 601 and the second motor 605. The first motor 601 drives the first rotating shaft 602 to rotate. Since the first rotating shaft 602 is fixedly connected to the cleaning bin 5, the cleaning bin 5 will rotate accordingly. At the same time, the second motor 605 drives the third rotating shaft 606 to rotate in the cleaning bin 5 in the direction opposite to that of the first rotating shaft 602. The cleaning rack 607 fixed on the third rotating shaft 606 rotates accordingly. The first cleaning brush 608 inside the cleaning rack 607 and the second cleaning brush 609 outside will clean the coal blocks in all directions, ensuring that all surfaces including the concave parts are thoroughly cleaned. After the cleaning is completed, start the third motor 702. The third motor 702 drives the lead screw 703 to rotate in the first strip-shaped square tube 701. Since the lead screw 703 is threadedly connected to the first slider 704, the rotation of the lead screw 703 will drive the first slider 704 to slide along the inner wall of the first strip-shaped square tube 701. The movement of the first slider 704 drives the first connecting block 705 and the discharge baffle 706 to move outward, so that the cleaned coal blocks fall onto the inclined discharge sieve housing 3 and finally enter the collection box 4 after rolling. The silt and water generated during the cleaning process are discharged through the drain pipe 8 fixed to the bottom surface of the inclined discharge sieve housing 3. Thus, this device can effectively clean the coal blocks, greatly improving the cleaning efficiency and quality, and at the same time reducing the complexity and labor intensity of manual operation.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
