Description

Technical Field

[0001] The utility model relates to the field of thickeners, in particular to a thickener with a thermal separation function. Background Art

[0002] A thickener is a solid-liquid separation equipment based on gravity sedimentation. It is usually a cylindrical shallow trough with a conical bottom built with concrete, wood or metal welded plates as structural materials. The cylindrical shallow trough is also equipped with motors and rakes. When processing slag, the slag mixed with water enters the thickener for sedimentation. The slag settles at the bottom of the thickener, and the upper water flows out through the overflow weir.

[0003] The existing patent (publication number: CN217220311U) discloses "a deep cone thickener with a dilution device, belonging to the technical field of thickeners. The deep cone thickener with a dilution device includes a thickener body and a dilution component, the thickener body includes a shell, a fixed plate, a first motor, a rake and a discharge pipe, the dilution component includes a support plate, a box body, a spiral stirring paddle, a second motor, a liquid pump and a discharge pipe, the support plate is arranged on the top of the shell, the box body is installed on the top of the support plate, and the spiral stirring paddle is rotatably arranged in the box body. By arranging the shell, the fixed plate, the first motor, the rake and the discharge pipe, solid-liquid separation can be performed. By arranging the support plate, the box body, the spiral stirring paddle, the second motor, the liquid pump and the discharge pipe, the tailings slurry can be mixed and diluted first, thereby improving the settling efficiency. At the same time, the upper clarified liquid in the shell is utilized, saving water resources."

[0004] However, the utility model has the following problems: when the thickener is used for a long time, since the first motor is fixedly connected to the rake frame, rake arms and rake teeth, the rake frame, rake arms and rake teeth are in contact with the slurry for a long time, which will cause the slurry to adhere to and remain on their surface. When maintenance and cleaning are required, it is inconvenient to maintain the rake arms and rake teeth separately, which makes it inconvenient to use. Therefore, the utility model provides a thickener with a thermal separation function to solve the problems raised in the above background technology. Utility Model Content

The rake arm 17 and the rake teeth 18 are driven by slow rotation to push the sludge accumulated at the lower end. The conveying mechanism 10 is fixedly arranged at the midpoint of one side of the outer wall of the shell 4 through a fixed seat 8. A feed box 12 is fixedly arranged on one side of the upper end surface of the conveying mechanism 10, and a processing box 11 is fixedly arranged on the other side of the upper end surface. A mounting plate is fixedly provided at the upper end of one side opposite to the processing box 11 and the feed box 12, and a pump body 13 is fixedly provided at the midpoint of the upper end of the mounting plate. A protective shell is fixedly sleeved on the outer side of the drive motor 1, and the protective shell can be used to protect the drive motor 1 to increase its service life. A No. 1 filter 19 and a No. 2 filter 22 are fixedly provided at the midpoints of both sides of the inner walls of the feed box 12 and the processing box 11, respectively. The filter screens filter larger particles of impurities, wherein the filter hole diameter of the No. 2 filter 22 is smaller than the filter hole diameter of the No. 1 filter 19, and a pump body 13 is fixedly provided at the upper end of one side of the outer wall of the feed box 12.

[0035] Specifically, according to the above embodiment, one end of the output shaft 1502 is fixedly sleeved on the output end of the driving motor 1, and the inner wall of the other end of the output shaft 1502 is provided with slots on both sides, and the upper ends of the two clamping blocks 1501 are respectively clamped in the two slots, and the inner wall of the sleeve rod 1507 is provided with clamping grooves on both sides, and the lower ends of the two clamping blocks 1501 are respectively clamped in the two clamping grooves.

[0036] When in use, the output shaft 1502 is driven to rotate by the driving motor 1. Since the output shaft 1502 is clamped on the block 1501 outside the rotating shaft 1504, and the sleeve rod 1507 is also clamped on the block 1501 and clamped with the output shaft 1502, when the output shaft 1502 rotates, it drives the rotating shaft 1504 and the sleeve rod 1507 to rotate synchronously, and then drives the rake arm 17 and the rake teeth 18 at the lower end to rotate. When the rake arm 17 and the rake teeth 18 need to be cleaned, the driving motor 1 at the upper end can be disassembled together with the fixing plate 2 to cause the output shaft 1502 to disengage from the block 1501 outside the rotating shaft 1504. At this time, the sleeve rod 1507 can be lifted up to drive the rake arm 17 and the rake teeth 18 at the lower end to complete the disassembly, cleaning or replacement.

[0037] Specifically, according to the above embodiment, the pump body 13 is connected to the feed box 12 and the overflow tank 3 through two conduits 23, respectively. The lower end of the overflow tank 3 is connected to the treatment box 11 through a connecting pipe 21, and a No. 2 valve 20 is fixedly sleeved on the outer side of the connecting pipe 21. When it is necessary to inject water into the feed box 12, the pump body 13 can be started, and the pump body 13 pumps the supernatant in the overflow tank 3 through one of the conduits 23, and injects it into the feed box 12 through the other conduit 23. When it is necessary to discharge the supernatant, the No. 2 valve 20 at the lower end is opened so that the supernatant is injected into the treatment box 11 through the connecting pipe 21, and the smaller suspended particles are filtered under the filtration of the No. 2 filter screen 22 in the treatment box 11, thereby reducing the amount of impurities remaining in the supernatant.

[0038] Specifically, according to the above embodiment, the conveying mechanism 10 includes a conveying tank 1003, a conveying motor 1002 is fixedly provided on one side of the outer wall of the conveying tank 1003, and a spiral stirring paddle 1001 is fixedly provided at the output end of the conveying motor 1002. When in use, the slurry is poured from the upper end of the feed box 12, and the slurry after filtering the larger particles through the No. 1 filter screen 19 is injected into the conveying tank 1003, and the supernatant pumped into the pump body 13 is also injected into the conveying tank 1003, so that the initial slurry is diluted by the supernatant, and the diluted slurry is sent into the shell 4 under the action of the conveying motor 1002 and the spiral stirring paddle 1001.

[0039] Specifically, according to the above embodiment, one side of the lower end surface of the conveying mechanism 10 is connected to the shell 4 through the conveying pipe 9, and the conveying pipe 9 passes through the shell 4 and is located at the upper end of the rake arm 17. The diluted slurry is delivered into the shell 4 through the above conveying mechanism 10, and the diluted slurry can be directly injected into the lower end of the shell 4, reducing the impact mixing force falling from the top and accelerating the sedimentation efficiency.

[0040] Working principle: When the machine is used, the initial slurry is injected from the upper end of the feed box 12, and the pump body 13 is started to pump the supernatant stored in the overflow tank 3 into the feed box 12. The initial slurry is filtered through the No. 1 filter screen 19 and diluted by the supernatant in the feed box 12, which reduces the doping of large particles in the slurry. The diluted slurry and the supernatant both fall into the conveying mechanism 10 and are conveyed and mixed by the spiral stirring paddle 1001, and are further diluted and evenly conveyed to the shell 4; and the stirring mechanism 15 arranged in the shell 4 can not only drive the rake arm 17 and the rake teeth 18 at the lower end to rotate, but also the entire stirring mechanism 15 can be distributed and disassembled for use, which is convenient for the later maintenance, replacement and cleaning of the rake arm 17 and the rake teeth 18.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
