Description

Technical Field

[0001] The utility model relates to the technical field of sewage sludge cleaning devices, in particular to a sludge cleaning device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements of a certain water body or reuse. Different treatment methods are used according to the nature of the impurities that pollute the water body. However, no matter which method is used, the wastewater needs to be left to stand to allow the impurities to settle, and then the sediment and the water body need to be separated. After the sediment is gathered, it will become sludge. The sludge produced after the sewage is settled needs to be cleaned up in time to avoid affecting the next sewage settlement.

[0003] Existing sludge removal devices for sewage treatment usually use scrapers to push the sludge toward the sludge pump. However, when the scrapers push the sludge, the sludge will flip from the upper edge of the scrapers to the back of the scrapers. Therefore, it takes multiple scrapers to scrape the sludge clean. Secondly, the current scrapers are all one-way scrapers, which are inefficient. Utility Model Content

[0031] Embodiment 1:

[0032] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0033] A sludge removal device for sewage treatment, comprising:

[0034] A sewage sedimentation tank 1 is provided with sludge extraction components 2 on the left and right sides of the sewage sedimentation tank 1. The sludge extraction components 2 are used to extract the sludge in the sewage sedimentation tank 1. A sludge pushing device 3 is provided inside the sewage sedimentation tank 1.

[0035] The sewage sedimentation tank 1 is a well-known sewage sedimentation tank, which is used for sewage sedimentation.

[0036] The sludge extraction assembly 2 includes sludge pumps 21, which are located outside the left and right sides of the sewage sedimentation tank 1, with four on each side. An extraction pipe 22 is fixedly connected to the bottom of each sludge pump 21 by bolts, and the extraction pipe 22 is connected to the bottom of the side of the sewage sedimentation tank 1. A sludge discharge pipe 23 is fixedly connected to the top of the sludge pump 21 by bolts.

[0037] The sludge pump 21 adopts a known sludge extraction pump. After the sludge pump 21 is started, the sludge at the bottom of the sewage sedimentation tank 1 can be extracted through the extraction pipe 22 and then discharged from the sludge discharge pipe 23, so as to facilitate the sludge to be processed in the next step.

[0038] The mud pushing device 3 includes a mud pushing plate 37, and both ends of the mud pushing plate 37 are connected to the limit assembly 4 and the driving device through a push plate fixing block 35. The driving device is used to drive the mud pushing plate 37 to reciprocate left and right, and the mud pushing plate 37 is used to push the sludge. A telescopic guide column 36 is provided on the outer side of the bottom of the push plate fixing block 35, and the telescopic guide column 36 is slidably connected to the limit assembly 4. The driving device includes a first motor 31, and the output shaft of the first motor 31 is fixedly connected to the first lead screw 32 through a coupling, and the first lead screw 32 is threadedly connected to the first slider 33. The first slider 33 is fixedly installed with a transmission plate 34 by bolts on one side facing the inside of the sewage sedimentation tank 1, and the transmission plate 34 is rotatably connected to the push plate fixing block 35.

[0039] The first motor 31 is fixedly installed on the edge of the top surface of the sewage sedimentation tank 1 by bolts. The first motor 31 can be a servo motor or a stepper motor that can rotate forward and reverse. After the first motor 31 is started, it can drive the first lead screw 32 to rotate through the output shaft. Since the first lead screw 32 is threadedly connected to the first slider 33, when the first lead screw 32 rotates, it can drive the first slider 33 to move along the axis direction of the first lead screw 32, thereby driving the transmission plate 34 to move left and right.

[0040] The push plate fixing block 35 includes a fixing block 351 , a rotating column 352 is threadedly installed on the top side of the fixing block 351 , the rotating column 352 is rotatably connected to the transmission plate 34 , a mounting groove 353 is provided at the bottom of the push plate fixing block 35 , and the telescopic guide column 36 is located at the mounting groove 353 .

[0041] When the transmission plate 34 moves left and right, the fixed block 351 can be driven to move left and right through the rotating column 352 , and the fixed block 351 can be rotated relative to the transmission plate 34 through the rotating column 352 .

[0042] The mounting groove 353 includes a telescopic rod 361, which is slidably installed in the mounting groove 353. A thrust ring 362 is welded to the middle of the telescopic rod 361, and a return spring 363 is provided between the thrust ring 362 and the bottom of the mounting groove 353. A limit ring 364 is threadedly installed at the opening of the mounting groove 353, and the head of the telescopic rod 361 passes through the limit ring 364.

[0043] The telescopic rod 361 is a cylindrical metal rod, the end of the telescopic rod 361 is spherical, the return spring 363 is sleeved on the tail of the telescopic rod 361, and the two ends of the return spring 363 are respectively against the bottom surface of the installation groove 353 and the thrust ring 362. The outer diameter of the thrust ring 362 is the same as the inner diameter of the installation groove 353.

[0044] When the head of the telescopic rod 361 is subjected to axial pressure, it moves along the axis direction of the installation slot 353, and compresses the return spring 363 through the thrust ring 362. When the pressure on the telescopic rod 361 disappears, the elastic force of the return spring 363 pushes the thrust ring 362 outward along the axis direction of the installation slot 353, thereby pushing the telescopic rod 361 to move outward along the axis direction of the installation slot 353.

[0045] The limiting assembly 4 includes a limiting plate 41 , and a limiting groove is provided on the side of the limiting plate 41 . The telescopic guide column 36 can slide along the limiting groove, thereby driving the mud pusher plate 37 to slide along the limiting groove.

[0046] There are two limit plates 41 , which are nested and installed on the bottom surfaces of the front and rear sides of the sewage sedimentation tank 1 .

[0047] The limiting grooves include a forward limiting groove 42 and a backward limiting groove 43 . The backward limiting groove 43 is located above the forward limiting groove 42 . The head of the telescopic rod 361 can slide along the forward limiting groove 42 and the backward limiting groove 43 .

[0048] The forward limiting groove 42 and the backward limiting groove 43 are both L-shaped, and are divided into a horizontal section and an inclined section. The head of the telescopic rod 361 is inserted into the forward limiting groove 42 and the backward limiting groove 43. When the telescopic guide column 36 moves left and right, the telescopic guide column 36 slides along the forward limiting groove 42 and the backward limiting groove 43. Thus, the bottom of the mud pusher 37 moves along the path of the forward limiting groove 42 and the backward limiting groove 43.

[0049] The forward limiting groove 42 and the backward limiting groove 43 are connected end to end to form a parallelogram, and a non-returning protrusion 44 is provided at the connection between the forward limiting groove 42 and the backward limiting groove 43.

[0050] When the push plate fixing block 35 moves to the right, the telescopic guide column 36 moves to the right along the horizontal section of the forward limit groove 42. At this time, the bottom surface of the first push plate 371 abuts against the bottom surface of the sewage sedimentation tank 1 and moves to the right. When the telescopic guide column 36 slides from the horizontal section of the forward limit groove 42 to the inclined section of the backward limit groove 43, the push plate fixing block 35 moves to the left. At this time, the non-return protrusion 44 can prevent the telescopic guide column 36 from returning from the backward limit groove 43 to the forward limit groove 42. The telescopic guide column 36 can only move upward along the non-return protrusion 44. At this time, the first push plate 371 rotates upward, and the second push plate 372 rotates downward. When the telescopic guide column 36 enters the horizontal section of the backward limit groove 43, the bottom surface of the second push plate 372 abuts against the bottom surface of the sewage sedimentation tank 1.

[0051] The push plate fixing block 35 continues to move to the left, and the telescopic guide column 36 moves to the right along the horizontal section of the retreat limit groove 43. At this time, the bottom surface of the second push plate 372 abuts against the bottom surface of the sewage sedimentation tank 1 and moves to the left. Until the telescopic guide column 36 slides from the horizontal section of the retreat limit groove 43 into the inclined section of the forward limit groove 42 and is blocked by the non-return protrusion 44 again, the push plate fixing block 35 changes the direction of movement and moves to the right. The telescopic guide column 36 moves downward and rightward under the blockage of the non-return protrusion 44. At this time, the first push plate 371 rotates downward, and the second push plate 372 rotates upward. When the telescopic guide column 36 enters the horizontal section of the forward limit groove 42, the bottom surface of the first push plate 371 abuts against the bottom surface of the sewage sedimentation tank 1.

[0052] When the operator of this embodiment uses the equipment, he injects sewage into the sewage sedimentation tank 1, and after the sewage is precipitated, the upper layer of clean water is discharged, and then the sludge pump 21 is started to extract the sludge on the left and right sides of the sewage sedimentation tank 1 through the extraction pipe 22, and then discharges it from the sludge discharge pipe 23.

[0053] At the same time, the first motor 31 is started, and the first motor 31 can drive the first sliding block 33 to move rightward through the first lead screw 32 , thereby driving the push plate fixing block 35 to move rightward through the transmission plate 34 .

[0054] At this time, the telescopic guide column 36 moves to the right along the horizontal section of the forward limiting groove 42, and at the same time, the bottom surface of the first push plate 371 abuts against the bottom surface of the sewage sedimentation tank 1 and moves to the right, pushing the sludge to the right, and the sludge is pumped out by the right sludge pump 21.

[0055] When the telescopic guide column 36 slides from the horizontal section of the forward limit groove 42 to the inclined section of the backward limit groove 43, the first motor 31 drives the push plate fixing block 35 to move leftward. At this time, the non-return protrusion 44 can prevent the telescopic guide column 36 from returning from the backward limit groove 43 to the forward limit groove 42. The telescopic guide column 36 can only move upward along the non-return protrusion 44. At this time, the first push plate 371 rotates upward, and the second push plate 372 rotates downward. When the telescopic guide column 36 enters the horizontal section of the backward limit groove 43, the bottom surface of the second push plate 372 abuts against the bottom surface of the sewage sedimentation tank 1.

[0056] The push plate fixing block 35 continues to move to the left, and the telescopic guide column 36 moves to the right along the horizontal section of the retreat limit groove 43. At this time, the bottom surface of the second push plate 372 abuts against the bottom surface of the sewage sedimentation tank 1 and moves to the left, pushing the sludge to the left, and the sludge is pumped out by the sludge pump 21 on the left.

[0057] Until the telescopic guide column 36 slides from the horizontal section of the backward limit groove 43 into the inclined section of the forward limit groove 42 and is blocked by the non-return protrusion 44 again, the first motor 31 drives the push plate fixing block 35 to change the direction of movement and move to the right. The telescopic guide column 36 moves downward and rightward under the blockage of the non-return protrusion 44. At this time, the first push plate 371 rotates downward and the second push plate 372 rotates upward. When the telescopic guide column 36 enters the horizontal section of the forward limit groove 42, the bottom surface of the first push plate 371 abuts against the bottom surface of the sewage sedimentation tank 1. The first push plate 371 moves to the right following the push plate fixing block 35, pushing the sludge to the right. The sludge is pushed to the extraction pipe 22 again.

[0058] Repeat the above steps until the sludge is removed.
