Description

Technical Field

[0001] The present invention relates to the technical field of sludge-water separation treatment, and particularly relates to a centrifugal treatment device for construction site sludge-water. Background Art

[0002] During the construction process of building projects, operations such as concrete mixing and earth excavation will generate a large amount of muddy water mixture containing solid particles. Such wastewater needs to be subjected to solid-liquid separation treatment before being discharged;

[0003] There are many ways to treat sludge-water, and centrifugal sedimentation is one of them. The separation of sludge-water is achieved through a centrifugal barrel that rotates at a high speed. A liquid retaining barrel is provided on the outer wall of the centrifugal barrel to stop the liquid being thrown out. The separated clear water is discharged through the through holes in the barrel wall, while the solid particles are deposited in the barrel; when the sludge-water centrifugal separation equipment is performing centrifugal treatment, the through holes on the outer wall of the centrifugal barrel are often prone to blockage problems, affecting the separation efficiency;

[0004] In the prior art, some liquid retaining barrels are provided with scraping plates, but the scraping plates scrape along the circumferential direction of the centrifugal barrel. The circumferential scraping method can only remove attachments in a single direction. The solid particles scraped off will be re-attached to the barrel wall in adjacent areas under the action of centrifugal force, forming a vicious cycle of "scraping-re-attaching"; when the centrifugal barrel rotates at a high speed, since the liquid retaining barrel remains stationary, the solid particles thrown out will rebound after colliding with the inner wall of the stationary liquid retaining barrel, and the thrown-out particulate matter will rebound onto the centrifugal barrel, increasing the attachments on the outer wall of the centrifugal barrel and making it more difficult for the scraping plate to clean. Summary of the Invention

[0024] The present invention provides a construction site muddy water centrifugal treatment device. Compared with the prior art, it has the following beneficial effects:

[0025] 1. The liquid retaining barrel can rotate synchronously with the centrifugal barrel. In this way, when the liquid thrown out of the centrifugal barrel contacts the liquid retaining barrel, it will not be subjected to a large impact force, and the particles will not rebound in large quantities, which solves the problem of rebounding particles clogging the outer wall of the centrifuge and reduces the probability of clogging the centrifugal barrel;

[0026] A cleaning piece is added to the inner wall of the liquid retaining barrel, and the hammer assembly can reciprocate and hammer the liquid retaining barrel downward, so that the liquid retaining barrel drives the cleaning piece to rotate, and the cleaning piece can also move vertically to scrape and clean the outer wall of the centrifugal barrel, so that the liquid retaining barrel can be synchronously rotated while the outer wall of the centrifugal barrel can be cleaned normally. Compared with scraping in the circumferential direction, the vertical scraping cleaning method has a greater cutting force on the attachments, and the attachments cut off are not easy to attach to the outer wall of the centrifugal barrel again, so the cleaning effect is better.

[0027] 2. The shovel box can be inserted and docked onto the rotating assembly. In this way, the rotation of the rotating assembly can drive the shovel box to rotate, thereby completely cleaning the sludge in the sedimentation tank. The shovel box can complete the comprehensive cleaning of the sedimentation tank with one rotation. At the same time, the cleaning operation is not affected by the fluidity and agglomeration of the sediment, and has a wider range of applications than traditional suction methods.

The cleaning parts 330 are located below the elastic connecting ring 320 and are attached to the outer wall of the centrifugal barrel 210; a hammering assembly 600 is provided on the top surface of the installation table 100; the elastic connecting ring 320 is used to make the liquid blocking barrel 310 and the centrifugal barrel 210 rotate synchronously; during the rotation of the liquid blocking barrel 310, the hammering assembly 600 hammers the convex ring 311 to make the liquid blocking barrel 310 move up and down, so that the cleaning parts 330 vertically clean the blockages on the outer wall of the centrifugal barrel 210

[0055] The precipitation unit 400 includes a sedimentation tank 410. The sedimentation tank 410 is circular. An annular liquid discharge hole 411 is provided at the top of the sedimentation tank 410. An annular liquid discharge cover 420 is provided on the outer wall of the sedimentation tank 410. A perforation is provided on the side of the sedimentation tank 410. An inlet and outlet frame 412 is provided outside the perforation. A sealing plate 440 is vertically slidably installed inside the inlet and outlet frame 412. An adjusting screw 441 is provided on the bottom surface of the inlet and outlet frame 412. The sealing plate 440 is threadedly sleeved on the adjusting screw 441. Rotating the adjusting screw 441 can drive the sealing plate 440 to move up and down.

[0056] The sludge removal unit 500 includes a screw guide rail 510 and a transfer assembly 530. The screw guide rail 510 is vertically provided on the side of the inlet and outlet frame 412. A push plate 520 is slidably installed on the side wall of the screw guide rail 510. A transfer assembly 530 is provided on the inner wall of the push plate 520. The transfer assembly 530 is cooperatively clamped and connected to a sludge shoveling box 540.

[0057] The rotating assembly 700 is installed at the center of the inner bottom surface of the sedimentation tank 410. The rotating assembly 700 is movably docked with the sludge discharge assembly 220. The transfer assembly 530 advances to first insert the sludge shoveling box 540 onto the rotating assembly 700. The transfer assembly 530 retreats to pull out the sludge shoveling box 540 and drive the sludge shoveling box 540 to flip and dump. The rotating assembly 700 is used to rotate and stir the liquid in the sedimentation tank 410 during the flocculation and mixing stage, and drive the sludge shoveling box 540 to rotate to remove the materials at the bottom of the sedimentation tank 410 during the sludge removal stage.

[0058] In the above solution:

[0059] 1. After the external muddy water is input into the centrifugal bucket 210 of the centrifugal unit 200, the first motor 110 is used to drive the gear ring 211 on the outer wall of the top of the centrifugal bucket 210 to rotate, thereby driving the centrifugal bucket 210 to rotate, realizing the separation of the muddy water. The mud blocks fall to the bottom of the centrifugal bucket 210 and can be quickly lifted and discharged by the sludge discharge assembly 220. The mud blocks can be discharged in real time without being blocked at the bottom of the centrifuge, and the separation and discharge efficiency is higher.

[0060] 2. The setting of the liquid blocking unit 300 can achieve the following effects:

[0061] The liquid blocking bucket 310 can rotate synchronously with the centrifugal bucket 210. In this way, when the liquid thrown out by the centrifugal bucket 210 contacts the liquid blocking bucket 310, it will not be subjected to a large impact force, and the particulate matter will not be impacted and rebound in large quantities, solving the problem of the particulate matter that rebounds and blocks the outer wall of the centrifuge, and reducing the probability of blockage of the centrifugal bucket 210.

[0062] A cleaning piece 330 is additionally provided on the inner wall of the liquid retaining barrel 310, and the hammer assembly 600 can reciprocately hammer the liquid retaining barrel 310 downward, so that while the liquid retaining barrel 310 drives the cleaning piece 330 to rotate, the cleaning piece 330 can also vertically move to scrape and clean the outer wall of the centrifugal barrel 210, so that the liquid retaining barrel 310 can be synchronously rotated while the outer wall of the centrifugal barrel 210 can be cleaned normally, and the vertical scraping and cleaning method is adopted. Compared with scraping in the circumferential direction, the cutting force for the attached objects is greater, and the attached objects cut off are not easy to be attached to the outer wall of the centrifugal barrel 210 again, and the cleaning effect is better;

[0063] The elastic connecting ring 320 can ensure that the liquid retaining barrel 310 is rotatably mounted on the bottom surface of the mounting platform 100, and can rotate synchronously with the centrifugal barrel 210 and can also perform normal lifting and lowering actions;

[0064] 3. The sedimentation unit 400 can precipitate and flocculate the discharged wastewater again, and the upper clean liquid is discharged in real time through the drainage hole 411 and the drainage cover 420, while the particles are precipitated under the action of the flocculant;

[0065] 4. The setting of the mud removal unit 500 can achieve the following effects:

[0066] An external shovel box 540 is used. When the sludge needs to be processed, it is inserted into the sedimentation tank 410 for cleaning. When it does not need to be cleaned, it is stored in the transfer assembly 530, which does not occupy the space in the sedimentation tank 410 and does not cause a lot of sludge to adhere to the outer wall of the shovel box 540.

[0067] The shovel box 540 extends into the sedimentation tank 410 without any power measures, and the rotating assembly 700 is at the bottom of the sedimentation tank 410, and it is difficult to set up a driving structure. In order to solve the above problems, the following solutions are given: the rotating assembly 700 is movably docked with the sludge discharge assembly 220, so that the docking state of the two can be controlled to control whether the rotating assembly 700 rotates, so that the rotating assembly 700 does not need to be separately configured with a driving structure; the rotating assembly 700 can drive the liquid in the sedimentation tank 410 to rotate during the flocculation and mixing stage, thereby increasing the mixing efficiency of the liquid and the flocculant or other added treatment agent; during the sedimentation stage, the rotating assembly 700 does not work; during the mud removal stage, the shovel box 540 can be inserted and docked to the rotating assembly 700, so that the rotation of the rotating assembly 700 can drive the shovel box 540 to rotate, thereby comprehensively cleaning the sludge in the sedimentation tank 410, and the shovel box 540 can complete the comprehensive cleaning of the sedimentation tank 410 by rotating one circle, and at the same time, the cleaning operation is not affected by the fluidity and agglomeration of the sediment, and has a wider range of applications than the traditional suction method.

[0068] In this embodiment, the sludge discharge assembly 220 includes a discharge pipe 224 which is vertically arranged at the inner center of the centrifugal barrel 210. A dispersion plate 226 is provided on the outer wall of the discharge pipe 224. A positioning frame 221 is provided at the top of the discharge pipe 224, and the positioning frame 221 is fixed on the top surface of the installation table 100. A spiral blade 225 is installed inside the discharge pipe 224. A second motor 223 is installed at the top of the spiral blade 225, and the second motor 223 is fixedly connected to a first driving rod 222.

A discharge box 2241 is provided on the side wall at the top of the discharge pipe 224; an inner scraping rod 227 in a shape of " " is provided on the side wall of the discharge pipe 224, and the inner scraping rod 227 is used to scrape the sludge on the inner wall of the centrifugal barrel 210, and the spiral blade 225 is used to output the sludge gathered at the bottom of the centrifugal barrel 210.

[0069] In the above solution: during the centrifugation operation, the sludge gathers at the bottom of the centrifugal barrel 210. The second motor 223 drives the spiral blade 225 to rotate, and the spiral blade 225 drives the sludge at the bottom to rise. After rising to the top, the sludge is discharged through the discharge box 2241; the first driving rod 222 can drive the spiral blade 225 to move up and down, and then drive the insertion post 228 to move up and down, so as to control the docking or separation of the rotating assembly 700 and the spiral blade 225;

[0070] When the centrifugal barrel 210 rotates, the inner scraping rod 227 remains stationary, and the inner scraping rod 227 scrapes the mud blocks attached to the inner wall of the centrifugal barrel 210.

[0071] In this embodiment, the elastic connection ring 320 includes an upper ring plate 321 which is fixed on the top of the outer wall of the centrifugal barrel 210. A plurality of spring rods 322 are provided on the bottom surface of the upper ring plate 321. The bottom end of each group of spring rods 322 is correspondingly provided with a group of lower support plates 323, and the plurality of lower support plates 323 are fixed on the inner wall of the liquid retaining barrel 310.

[0072] In the above solution: when the centrifugal barrel 210 rotates, it can first drive the upper ring plate 321 to rotate, and then drive the liquid retaining barrel 310 to rotate through the plurality of spring rods 322 and the lower support plates 323, so that the liquid retaining barrel 310 rotates synchronously with the centrifugal barrel 210. When the convex ring 311 is impacted, the liquid retaining barrel 310 descends, thereby stretching the spring rods 322, so that the liquid retaining barrel 310 can rotate normally.

[0073] In this embodiment, the hammering assembly 600 includes a fourth motor 610 and a contact plate 630. The fourth motor 610 is arranged on the surface of the installation table 100. The output end of the fourth motor 610 is connected to an eccentric wheel 620. A contact post 621 is provided on the outer wall of the eccentric wheel 620. The contact plate 630 vertically slides through the installation table 100. The bottom end of the contact plate 630 abuts against the surface of the convex ring 311. A rectangular frame 640 is provided at the top of the contact plate 630, and the contact post 621 extends into the rectangular frame 640.

[0074] In the above solution: The fourth motor 610 can drive the eccentric wheel 620 to rotate, and then drive the contact post 621 to rotate. The contact post 621 contacts the rectangular frame 640 to move up and down, and finally makes the contact plate 630 slide vertically along the mounting table 100. The bottom end of the contact plate 630 can reciprocally press down the convex ring 311.

[0075] In this embodiment, the cleaning member 330 includes a support rod 331. A plurality of groups of support rods 331 are vertically fixed on the inner wall of the liquid retaining barrel 310. A vertical plate 333 is vertically provided at the inner ends of the plurality of groups of support rods 331.

The scraping ring 332 is an arc structure, and the scraping ring 332 is fitted between the through holes on the outer wall of the centrifugal barrel 210.

[0076] In the above solution: When the liquid retaining barrel 310 rotates, it can drive the support rod 331 to rotate therewith, so that the scraping ring 332 remains relatively stationary with respect to the centrifugal barrel 210. When the hammering assembly 600 works, the liquid retaining barrel 310 moves up and down. Through the support rod 331 and the vertical plate 333, a plurality of groups of scraping rings 332 are driven to move up and down synchronously. The scraping ring 332 can then vertically cut off the attachments on the through holes at the bottom of the centrifugal barrel 210 to achieve efficient cleaning; the scraping ring 332 can be a quarter-arc structure, and four groups of cleaning members 330 are provided.

[0077] In this embodiment, an annular blocking cover 430 is concentrically provided inside the sedimentation tank 410.

[0081] A rectangular rotating rod 720 is provided on the side wall of the central shaft tube 710. When the plug post 228 is inserted into the polygonal groove 711, the spiral blade 225 rotates to drive the rectangular rotating rod 720 to rotate.

[0082] In order to achieve rapid scraping treatment of sediment sludge and solve the problems of low efficiency of manual salvage and many limitations of traditional suction type, the following solution is given in this embodiment:

[0083] In this embodiment, the mud scraping box 540 has a cuboid structure. One side surface of the mud scraping box 540 is an open structure. A slot 541 is formed in the middle of the bottom surface of the mud scraping box 540. Insertion strips 542 are symmetrically arranged on the inner wall of the slot 541. The rectangular rotating rod 720 is inserted into the slot 541 in a matching manner. Locking grooves 543 are symmetrically formed on the outer bottom surface of the mud scraping box 540.

[0084] When the mud scraping box 540 is inserted into the sedimentation tank 410, the mud scraping box 540 is horizontally inserted onto the rectangular rotating rod 720. The inner end of the mud scraping box 540 extends below the centrifugal barrel 210, and the outer end extends to the inner wall of the sedimentation tank 410.

[0085] In this embodiment, the transfer assembly 530 includes a rotating shaft 531. One end of the rotating shaft 531 is vertically and rotatably connected to the pushing plate 520, and the other end is vertically and rotatably connected to the clamping plate 533. A third motor 532 is provided on the inner wall of the pushing plate 520. The third motor 532 drives the rotating shaft 531 to rotate. A clamping plate 533 is fixedly provided at the outer end of the rotating shaft 531. A U-shaped movable frame 535 horizontally slides through the bottom of the clamping plate 533. A second driving rod 534 is provided on the outer wall of the clamping plate 533. The second driving rod 534 is arranged below the rotating shaft 531. The output end of the second driving rod 534 is connected to the U-shaped movable frame 535. The two outer extension tubes 5351 of the U-shaped movable frame 535 are inserted into the locking grooves 543 in a matching manner.

[0086] In this embodiment, a bidirectional drive rod 536 is provided at the outer end of the U-shaped movable frame 535. Locking plates 537 are provided at both ends of the bidirectional drive rod 536. An activity groove 5352 is formed in the outer extension pipe 5351 of the U-shaped movable frame 535. The locking plates 537 are slidably inserted into the activity groove 5352. A locking block 538 is provided on the outer wall of the inner end of the locking plate 537. A notch 5352 is formed at the inner end of the activity groove 5352. The locking block 538 is received in the activity groove 5352 or extends out of the notch 5352. A side groove 544 is formed on the inner side surface of the locking groove 543. When the locking block 538 extends out, it is inserted into the side groove 544.

[0087] In the above solution:

[0088] When the mud scraping box 540 is not in use, it is placed outside the sedimentation tank 410. At this time, the pushing plate 520 is placed at the outer end of the screw guide rail 510. The outer extension pipe 5351 is inserted into the locking groove 543. The bidirectional drive rod 536 extends out, so that the locking block 538 is inserted into the side groove 544 of the locking groove 543, thereby improving the docking strength of the U-shaped movable frame 535 to the mud scraping box 540;

[0089] When it is necessary to scrape the sludge, the blocking plate 440 descends and opens, and the slurry with better fluidity on the surface is discharged first. Subsequently, the screw guide rail 510 drives the pushing plate 520 to translate, so that the mud scraping box 540 passes through the inlet and outlet frame 412. The mud scraping box 540 is inserted on the rectangular rotating rod 720. The rectangular rotating rod 720 is relatively inserted into the insertion slot 541, and the insertion post 228 is cooperatively inserted into the polygonal groove 711; after the mud scraping box 540 is inserted, the U-shaped movable frame 535 is separated from the locking groove 543;

[0090] The second motor 223 drives the spiral blade 225 to rotate, thereby driving the middle shaft pipe 710 and the rectangular rotating rod 720 to rotate. The rotation of the rectangular rotating rod 720 drives the mud scraping box 540 to rotate, and the mud scraping box 540 scrapes the sludge with poor fluidity at the bottom of the sedimentation tank 410.
