Description

Technical Field

[0001] The present invention relates to the technical field of mud and water separation treatment, and in particular to a centrifugal treatment device for mud and water at a construction site. Background Art

[0002] During construction, operations such as concrete mixing and earth excavation will generate a large amount of mud-water mixture containing solid particles. This type of wastewater must be treated by solid-liquid separation before it can be discharged.

[0003] There are many ways to treat muddy water, and centrifugal sedimentation is one of them. This method uses a high-speed rotating centrifuge barrel to separate mud and water. A liquid retaining barrel is installed on the outer wall of the centrifuge barrel to stop the liquid from being thrown out. The separated clean water is discharged through the through-holes in the barrel wall, while the solid particles are deposited in the barrel. During the centrifugal treatment of muddy water centrifugal separation equipment, the through-holes on the outer wall of the centrifuge barrel are often prone to clogging, which affects the separation efficiency.

[0004] In the prior art, scrapers are installed in some liquid retaining barrels, but the scrapers scrape along the circumferential direction of the centrifugal barrel. The circumferential scraping method can only remove attachments in one direction. The scraped solid particles will be reattached to the barrel wall in the adjacent area under the action of centrifugal force, forming a vicious cycle of "scraping-reattachment"; when the centrifugal barrel rotates at high speed, since the liquid retaining barrel remains stationary, the thrown solid particles will collide with the inner wall of the stationary liquid retaining barrel and produce a rebound effect. The thrown particles will rebound onto the centrifugal barrel, causing an increase in attachments on the outer wall of the centrifugal barrel, which increases the difficulty of cleaning with the scraper.

[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.

[0051] In order to solve the technical problems in the background technology, the following construction site muddy water centrifugal treatment equipment is provided:

[0052] Combine Figures 1-13 As shown, the present invention provides a centrifugal treatment device for muddy water at a construction site, comprising a mounting platform, on the surface of which a first motor 110 and an addition pipe 120 for adding flocculants and other auxiliary agents are provided;

[0053] The centrifugal unit 200 includes a centrifugal bucket 210. The outer wall of the centrifugal bucket 210 has a mesh structure, an open top structure, and a conical closed bottom structure. The centrifugal bucket 210 is rotatably mounted in the middle of the mounting platform 100. The first motor 110 drives the centrifugal bucket 210 to rotate. A sludge discharge assembly 220 is provided in the middle of the centrifugal bucket 210. A gear ring 211 is provided on the outer wall of the top of the centrifugal bucket 210. The output end of the first motor 110 is meshed and connected to the gear ring 211.

[0054] The liquid retaining unit 300 includes a liquid retaining barrel 310, the top and bottom of which are both open structures. The liquid retaining barrel 310 is concentrically spaced and arranged outside the centrifugal barrel 210. The top inner wall of the liquid retaining barrel 310 is provided with an elastic connecting ring 320, and the top outer wall of the liquid retaining barrel 310 is provided with a convex ring 311; the inner wall of the liquid retaining barrel 310 is provided with multiple groups of cleaning members 330, which are located below the elastic connecting ring 320 and are attached to the outer wall of the centrifugal barrel 210; the top surface of the mounting platform 100 is provided with a hammer assembly 600; the elastic connecting ring 320 is used to make the liquid retaining barrel 310 rotate synchronously with the centrifugal barrel 210; during the rotation of the liquid retaining barrel 310, the hammer assembly 600 hammers the convex ring 311 to make the liquid retaining barrel 310 rise and fall, so that the cleaning members 330 vertically clean the blockage on the outer wall of the centrifugal barrel 210;

[0055] Sedimentation unit 400 includes a circular sedimentation tank 410 with an annular drainage hole 411 formed on the top and an annular drainage cover 420 formed on the outer wall of sedimentation tank 410. A perforation is formed on the side of sedimentation tank 410, and an inlet and outlet frame 412 is provided on the outer side of the perforation. A sealing plate 440 is vertically slidably mounted inside the inlet and outlet frame 412. An adjusting screw 441 is provided on the bottom surface of the inlet and outlet frame 412. Sealing plate 440 is threadably mounted on adjusting screw 441. Rotating adjusting screw 441 drives sealing plate 440 to move upward and downward.

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

[0057] The rotating assembly 700 is installed at the center of the inner bottom surface of the sedimentation tank 410, and the rotating assembly 700 is movably docked with the sludge discharge assembly 220; the transfer assembly 530 moves forward to first insert the mud shoveling box 540 onto the rotating assembly 700, and the transfer assembly 530 moves backward to extract the mud shoveling box 540 and drive the mud shoveling box 540 to flip and discharge the material; 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 mud shoveling box 540 to rotate during the mud removal stage to remove the material at the bottom of the sedimentation tank 410.

[0058] In the above scheme:

[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 top outer wall of the centrifugal bucket 210 to rotate, thereby driving the centrifugal bucket 210 to rotate, achieving the separation of muddy water. The mud blocks fall to the bottom of the centrifugal bucket 210 and can be quickly lifted up and discharged by the sludge discharge assembly 220. The mud blocks can be discharged in real time without clogging at the bottom of the centrifuge, thereby improving the separation and discharge efficiency.

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

[0061] The liquid retaining barrel 310 can rotate synchronously with the centrifugal barrel 210. In this way, when the liquid ejected from the centrifugal barrel 210 contacts the liquid retaining barrel 310, it will not be subjected to a large impact force, and the particles will not rebound in large quantities, thus solving the problem of rebounded particles clogging the outer wall of the centrifuge and reducing the probability of clogging the centrifugal barrel 210.

[0062] The cleaning member 330 is additionally provided on the inner wall of the liquid retaining barrel 310, and the hammer assembly 600 can reciprocate and hammer the liquid retaining barrel 310 downward, so that the liquid retaining barrel 310 drives the cleaning member 330 to rotate while the cleaning member 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 rotate synchronously while the outer wall of the centrifugal barrel 210 can be cleaned normally. In addition, the vertical scraping and cleaning method has a greater cutting force on the attachments than scraping in the circumferential direction, and the attachments cut off are not easily attached to the outer wall of the centrifugal barrel 210, so 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 movements;

[0064] 3. The sedimentation unit 400 can further precipitate and flocculate the discharged wastewater. 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 cleaning is not required, it is stored in the transfer assembly 530. This does not occupy the space in the sedimentation tank 410, nor does it cause a lot of sludge to adhere to the outer wall of the shovel box 540.

[0067] The shovel box 540 is inserted into the sedimentation tank 410 without any power supply, and the rotating assembly 700 is located at the bottom of the sedimentation tank 410, making it difficult to set up a drive structure. To solve the above problem, the following solution is provided: 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. In this way, the rotating assembly 700 does not need to be configured with a separate drive structure; during the flocculation and mixing stage, the rotating assembly 700 can drive the liquid in the sedimentation tank 410 to rotate, thereby increasing the mixing efficiency of the liquid with the flocculant or other added treatment agents; 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 with the rotating assembly 700. In this way, the rotation of the rotating assembly 700 can drive the shovel box 540 to rotate, thereby completely cleaning the sludge in the sedimentation tank 410. The shovel box 540 can complete the complete cleaning of the sedimentation tank 410 with one rotation of the shovel box 540. 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.

[0068] In this embodiment, the sludge discharge assembly 220 includes an outlet pipe 224, which is vertically arranged at the inner center of the centrifugal bucket 210. The outer wall of the outlet pipe 224 is provided with a dispersion plate 226, and the top of the outlet pipe 224 is provided with a positioning frame 221. The positioning frame 221 is fixed to the top surface of the mounting platform 100. A spiral blade 225 is installed inside the outlet pipe 224, and a second motor 223 is installed on the top of the spiral blade 225. The second motor 223 is fixedly connected to the first drive rod 222, and the first drive rod 222 is provided on the positioning frame 221. The top side wall of the outlet pipe 224 is provided with a discharge box 2241; the side wall of the outlet pipe 224 is provided with a 7-shaped inner scraper 227, the inner scraper 227 is used to scrape off the sludge on the inner wall of the centrifugal bucket 210, and the spiral blade 225 is used to output the sludge accumulated at the bottom of the centrifugal bucket 210.

[0069] In the above scheme, during centrifugal operation, sludge accumulates at the bottom of the centrifuge 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 being lifted to the top, the sludge is discharged through the discharge box 2241. The first drive rod 222 can drive the spiral blade 225 to move up and down, thereby driving the plug 228 to move up and down, thereby regulating the docking or separation of the rotating assembly 700 and the spiral blade 225.

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

[0071] In this embodiment, the elastic connecting ring 320 includes an upper ring plate 321, which is fixed to the top of the outer wall of the centrifugal barrel 210. The bottom surface of the upper ring plate 321 is provided with multiple groups of spring rods 322, and the bottom end of each group of spring rods 322 corresponds to a group of lower support plates 323, and multiple groups of lower support plates 323 are fixed to the inner wall of the liquid-blocking barrel 310.

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

[0073] In this embodiment, the hammer assembly 600 includes a fourth motor 610 and a contact plate 630. The fourth motor 610 is arranged on the surface of the mounting platform 100. The output end of the fourth motor 610 is connected to the eccentric wheel 620. The outer wall of the eccentric wheel 620 is provided with a contact column 621. The contact plate 630 slides vertically through the mounting platform 100. The bottom end of the contact plate 630 contacts the surface of the convex ring 311. The top of the contact plate 630 is provided with a rectangular frame 640, and the contact column 621 extends into the rectangular frame 640.

[0074] In the above scheme: the fourth motor 610 can drive the eccentric wheel 620 to rotate, thereby driving the resistance column 621 to rotate, and the resistance column 621 resists the rectangular frame 640 to move up and down, and finally makes the resistance plate 630 slide vertically along the mounting platform 100, and the bottom end of the resistance plate 630 can press the convex ring 311 back and forth.

[0075] In this embodiment, the cleaning part 330 includes support rods 331, and multiple groups of support rods 331 are vertically fixed to the inner wall of the liquid-blocking barrel 310. Vertical plates 333 are vertically provided at the inner ends of the multiple groups of support rods 331. The inner walls of the vertical plates 333 are provided with multiple groups of scraping rings 332 from top to bottom. The scraping rings 332 are arc structures, and the scraping rings 332 are fitly placed between the through holes on the outer wall of the centrifugal barrel 210.

[0076] In the above scheme: when the liquid retaining barrel 310 rotates, it can drive the support rod 331 to rotate accordingly, so that the scraper ring 332 and the centrifugal barrel 210 remain relatively stationary. When the hammer assembly 600 is working, the liquid retaining barrel 310 body moves up and down, and the support rod 331 and the vertical plate 333 drive multiple groups of scraper rings 332 to move up and down synchronously. The scraper ring 332 can vertically cut off the attachments on the through hole of the bottom centrifugal barrel 210 to achieve efficient cleaning; the scraper ring 332 can be a quarter arc structure, and four groups of cleaning parts 330 are provided.

[0077] In this embodiment, an annular blocking cover 430 is concentrically provided inside the sedimentation tank 410, and the blocking cover 430 is relatively spaced between the drainage hole 411 and the liquid blocking barrel 310. The top of the blocking cover 430 is fixedly connected to the top surface of the sedimentation tank 410 by a plurality of strips. The top surface of the blocking cover 430 is flush with the top surface of the sedimentation tank 410. A narrow liquid guide channel for liquid discharge is reserved between the blocking cover 430 and the sedimentation tank 410. A floating object temporary storage area is provided between the blocking cover 430 and the liquid blocking barrel 310. A suction pump is provided on the outer wall of the sedimentation tank 410, and a suction cover is provided at the inlet end of the suction pump. The suction cover is placed in the floating object temporary storage area.

[0078] In the above solution, the design of the blocking cover 430 can enclose floating objects and prevent them from being discharged. In this way, the floating objects can be sucked out by the negative pressure of the suction cover. The floating objects can be oil or floating garbage.
