Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0014] Reference Figure 1-Figure 5A waste residue treatment device for a coal-fired power plant comprises a central tube 1, a fixed ring 2 is fixedly sleeved inside the central tube 1, an annular tube 7 is arranged at the lower side of the fixed ring 2, two water inlet pipes 3 are symmetrically fixedly connected to the outer side of the annular tube 7, the two water inlet pipes 3 pass through the central tube 1 and are fixedly connected to the central tube 1, a plurality of nozzles 4 are evenly fixedly connected to the inner side of the annular tube 7, a limiting ring 13 is fixedly connected inside the central tube 1, the limiting ring 13 is located at the lower side of the fixed ring 2, a filter ring 14 is arranged at the lower side of the limiting ring 13, a plurality of threaded holes 18 are symmetrically arranged at the upper side of the filter ring 14, and a plurality of threaded holes 18 are symmetrically arranged at the upper side of the filter ring 14. A threaded rod 16 is provided in the threaded sleeve of the hole 18, and the threaded rod 16 passes through the threaded hole 18. A plurality of threaded grooves 17 are provided on the lower side of the limiting ring 13. The threaded rod 16 and the threaded grooves 17 are threadedly connected. A motor 5 is provided in the central tube 1. The motor 5 is arranged between the fixing ring 2 and the limiting ring 13. The motor 5 is fixedly connected to the central tube 1 through a plurality of inclined rods 6. A positioning rod 19 is fixedly connected to the lower side of the output shaft of the motor 5. Two rolling rollers 9 are provided on the outer rotating sleeve of the positioning rod 19. The two rolling rollers 9 are located on the upper side of the filter ring 14 and are against the filter ring 14.

[0015] First, a filter screen is fixedly connected inside the filter ring 14. When the waste residue needs to be crushed and filtered, a suitable filter screen is first selected and placed on the lower side of the limit ring 13, so that the threaded rod 16 passes through the threaded hole 18 and enters the threaded groove 17, and the installation operation of the filter ring 14 is completed. The waste residue to be processed is poured into the central tube 1, and clean water is poured into the annular tube 7 through the water inlet pipe 3. The clean water is sprayed onto the waste residue through the annular tube 7 and the nozzle 4, and the motor 5 is started. The motor 5 drives the crushing roller 9 to rotate around the motor 5 through the positioning rod 19, and the waste residue on the upper side of the filter ring 14 is crushed. The waste residue that meets the requirements of the filter screen is filtered out of the filter screen, and the waste residue that does not meet the requirements is crushed by the crushing roller 9, so that most of them meet the requirements of the filter screen and are filtered out of the filter screen. A fixed bevel gear ring 10 is fixedly connected to one side of the two rolling rollers 9 close to the output shaft of the motor 5. A rotating bevel gear 8 is fixedly sleeved on the outer side of the output shaft of the motor 5. The rotating bevel gear 8 and the fixed bevel gear ring 10 are meshed with each other. After the motor 5 is started, the motor 5 drives the fixed bevel gear ring 10 to rotate by rotating the bevel gear 8, thereby driving the rolling rollers 9 to rotate, so that the rolling rollers 9 rotate around the motor 5 as the center, and at the same time, they also rotate around the positioning rod 19 as the center, thereby achieving a better rolling effect. Two fixing plates 11 are symmetrically fixedly connected to the outer side of the positioning rod 19, and two contact plates 12 are symmetrically fixedly connected to the side walls of the two fixing plates 11. The two contact plates 12 are against the rolling roller 9. The contact plates 12 are used to simply clean the outer wall of the rolling roller 9, thereby improving the overall rolling effect of the device. A square rod 20 is slidably sleeved on the upper side of the two fixed plates 11, and the square rod 20 penetrates the fixed plate 11. A movable plate 22 is fixedly connected to the lower side of the square rod 20, and a plurality of arc-shaped rods 23 are evenly fixedly connected to the lower side of the movable plate 22. A curved rod 24 is slidably sleeved on the outer side of the plurality of arc-shaped rods 23. The curved rod 24 is connected to the movable plate 22 through a second spring 25, and the second spring 25 is sleeved on the outer side of the curved rod 23. The curved rod 23 is used to determine and limit the motion trajectory of the curved rod 24. The upper side of the square rod 20 is fixedly connected with a top plate 15, and the top plate 15 is connected to the fixed plate 11 through a first spring 21. The lower side of the top plate 15 is fixedly connected with an electromagnetic suction cup 26. The electromagnetic suction cup 26 and the fixed plate 11 are matched. First, the fixed plate 11 is a metal plate. The electromagnetic suction cup 26 is a machine tool accessory product produced based on the electromagnetic principle. The internal coil is energized to generate magnetic force, and the workpiece in contact with the surface of the panel is tightly sucked through the magnetic conductive panel. The coil is powered off and the magnetic force disappears to achieve demagnetization and remove the workpiece.

[0016] When the electromagnetic suction cup 26 is activated, the top plate 15 will move downward relative to the fixed plate 11. While the top plate 15 compresses the second spring 25, the moving plate 22 is driven downward by the square rod 20. The moving plate 22 drives the bending rod 24 to move downward through the arc rod 23. The bending rod 24 and the filter screen inside the filter ring 14 are abutted against each other, and the bending rod 24 is moved along the arc rod 23 until the end of the bending rod 24 away from the arc rod 23 is abutted against the filter screen. In the above-mentioned movement process, the bending rod 24 will also rotate around the motor 5 under the action of the fixed plate 11, so that the material that has not been crushed on the upper side of the filter screen can be collected.

[0017] First, select a suitable filter screen, place the filter screen on the lower side of the limit ring 13, make the threaded rod 16 pass through the threaded hole 18 and enter the threaded groove 17, complete the installation operation of the filter ring 14, pour the waste residue to be processed into the central tube 1, pour clean water into the annular tube 7 through the water inlet pipe 3, and the clean water is sprayed onto the waste residue through the annular tube 7 and the nozzle 4, start the motor 5, and the motor 5 drives the rolling roller 9 to rotate around the motor 5 as the center through the positioning rod 19, and the waste residue on the upper side of the filter ring 14 is rolled. The waste residue that meets the requirements of the filter screen is filtered out of the filter screen, and the waste residue that does not meet the requirements is rolled by the rolling roller 9, so that most of them meet the requirements of the filter screen and are filtered out by the filter screen. After the motor 5 is started, the motor 5 drives the fixed bevel gear ring 10 to rotate by rotating the bevel gear 8, and then drives the rolling roller 9 to rotate, so that the rolling roller 9 rotates around the motor 5 as the center, and also rotates around the positioning rod 19 as the center. The second spring 25 is compressed by the top plate 15, and the movable plate 22 is driven downward by the square rod 20. The movable plate 22 drives the curved rod 24 to move downward through the curved rod 23, and the curved rod 24 is abutted against the filter screen inside the filter ring 14, and the curved rod 24 is moved along the curved rod 23 until the end of the curved rod 24 away from the curved rod 23 is abutted against the filter screen, and in the above-mentioned moving process, the curved rod 24 will also rotate around the motor 5 under the action of the fixed plate 11, so that the material that has not been crushed on the upper side of the filter screen can be collected. The electromagnetic suction cup 26 is closed, and the curved rod 24 returns to its original position under the action of the first spring 21, and finally the collection operation of the material that cannot be crushed is completed.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
