Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to a mud removal device for industrial wastewater treatment. Background Art

[0002] Industrial wastewater refers to wastewater and waste liquid containing various pollutants generated during the industrial production process. These pollutants include but are not limited to industrial production materials, intermediates, products lost with water, and other harmful substances generated during the production process. In order to protect the environment and meet emission standards, industrial wastewater must undergo a series of treatment steps before discharge, such as sedimentation, filtration, aeration and disinfection.

[0003] In the process of wastewater treatment, sedimentation is a key step. It uses gravity to make suspended matter settle to the bottom to form a sludge layer, thereby achieving solid-liquid separation. However, in actual operation, the inner wall of the sedimentation tank is prone to adhesion of debris, forming a sludge layer that is difficult to remove, which not only affects the sedimentation efficiency, but may also lead to a decrease in effluent quality.

[0004] Traditional sludge cleaning methods mainly include mechanical scraping and emptying and cleaning. Mechanical scraping usually uses a scraper or manual method to physically scrape the inner wall of the sedimentation tank. Although this method can quickly remove the sludge on the surface, it is often unable to effectively collect the scraped sludge, causing some of the sludge to be re-mixed into the treated wastewater, causing secondary pollution. In addition, the scraping process may not be thorough enough, and some fine particles will still remain on the inner wall. Another common method is to completely drain the wastewater in the sedimentation tank and then clean it, but continuous flushing is also required during cleaning, which will also cause the sludge and water to mix, resulting in poor mud removal effect. Summary of the invention

[0005] The present application aims to solve one of the technical problems in the related art at least to some extent.

[0006] To this end, one purpose of the present application is to provide a mud removal device for industrial wastewater treatment.

DETAILED DESCRIPTION

[0029] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0030] The following describes a mud removal device for industrial wastewater treatment according to an embodiment of the present application in conjunction with the accompanying drawings.

[0031] like Figure 1-Figure 8 As shown, the mud removal device for industrial wastewater treatment of an embodiment of the present application includes a sedimentation tank 1, a water injection pipe 2 and a mud removal assembly 3, wherein the water injection pipe 2 is installed on the sedimentation tank 1, and one end of the water injection pipe 2 extends into the sedimentation tank 1.

[0032] It can be understood that the water injection pipe 2 is a water pipe for conveying sewage, which can convey the wastewater that needs to be precipitated into the sedimentation tank 1.

[0033] The mud removal assembly 3 includes multiple lifting mechanisms 31, a first driving mechanism 32, a rotating rod 33, a collecting box 34, a sealing plate 35, a first scraper 36, a positioning mechanism 37 and a cleaning mechanism 38, wherein the multiple lifting mechanisms 31 are distributed in a circular array on the outer wall of the sedimentation tank 1, the first driving mechanism 32 is installed on the lifting mechanism 31, the collecting box 34 is located below the first driving mechanism 32 and is movably arranged in the sedimentation tank 1, one end of the rotating rod 33 is connected to the rotating shaft of the first driving mechanism 32, and the other end of the rotating rod 33 is fixedly connected to one end of the collecting box 34.

[0034] It should be noted that the first driving mechanism 32 is a motor, which is used to drive the rotating rod 32 to rotate during use.

[0035] The sealing plate 35 is slidably disposed on the bottom surface of the collecting box 34 . The first scraper 36 is installed on the bottom surface of the collecting box 34 , and the first scraper 36 is triangular in shape.

[0036] It should be noted that when cleaning the sludge on the bottom wall of the sedimentation tank 1, the sealing plate 35 and the first scraper 36 block the cleaned sludge to prevent the sludge from flowing out from both sides of the sealing plate 35 and the first scraper 36, but the cleaned sludge will flow out from the other two sides of the collecting box 34. Therefore, it is necessary to install blocking plates on the other two sides of the collecting box 34. When cleaning the sludge, a sealed cavity can be formed at the bottom of the collecting box 34 to block the sludge and reduce the outflow of sludge.

[0037] The positioning mechanism 37 is slidably disposed in the collection box 34 , and the cleaning mechanism 38 is slidably disposed in the collection box 34 , and the cleaning mechanism 38 is located in the middle position of the collection box 34 .

[0038] Specifically, during actual use, a large amount of sludge will adhere to the inner wall of the sedimentation tank 1, and the sludge needs to be cleaned.

[0039] When the sludge needs to be cleaned, the first driving mechanism 32 is first moved by the lifting mechanism 31, and then the first driving mechanism 32 and the rotating rod 32 drive the collecting box 34 to move to the bottom of the sedimentation tank 1. After the first scraper 36 at the bottom of the collecting box 34 contacts the bottom surface of the sedimentation tank 1, the output end of the first driving mechanism 32 is controlled to drive the rotating rod 33 to rotate. The rotation of the rotating rod 33 will drive the collecting box 34 to rotate, and then the rotating collecting box 34 drives the first scraper 36 to clean the sludge at the bottom of the sedimentation tank 1. After cleaning, the sealing plate 35 can be pushed to collect the cleaned sludge in the collecting box 34.

[0040] Through the cooperation between the sealing plate 35 and the first scraper 36 on the bottom surface of the collecting box 34, the sludge on the bottom wall of the sedimentation tank 1 can be blocked while being cleaned, so that the sealing plate 35 can be used to seal the sludge in the collecting box 34 after the sludge is cleaned, so as to facilitate the subsequent collection and treatment of the cleaned sludge and avoid the problem of sludge flowing into the wastewater and requiring further treatment, which is time-consuming and labor-intensive.

[0041] In one embodiment of the present application, Figure 2 As shown, the length of the collecting box 34 is greater than the radius of the sedimentation tank 1 , and the collecting box 34 slides in the sedimentation tank 1 .

[0042] It is understandable that the length of the collecting box 34 is greater than the radius of the sedimentation tank 1, so that when the collecting box 34 rotates, the sedimentation tank 1 can be fully covered and cleaned, thereby reducing the residue after the sedimentation tank 1 is cleaned.

[0043] In one embodiment of the present application, Figure 5 As shown, the bottom end of the first scraper plate 36 and the bottom of the sealing plate 35 are on the same plane, and the end of the sealing plate 35 close to the first scraper plate 36 is designed as a slope.

[0044] It should be noted that the inclined surface design at one end of the sealing plate 35 allows one end of the sealing plate 35 to completely fit with the first scraper 36 when moving toward the first scraper 36 , so that the sealing plate 35 has a better sealing effect on the collection box 34 .

[0045] In one embodiment of the present application, Figure 2 As shown, the lifting mechanism 31 includes a support plate 311, an electric telescopic rod 312 and a transmission plate 313, wherein the support plate 311 is mounted on the sedimentation tank 1. The electric telescopic rod 312 is mounted on the support plate 311. The transmission plate 313 is mounted on the output end of the electric telescopic rod 312, and one end of the transmission plate 313 is located at the center of the sedimentation tank 1.

[0046] Before cleaning the sludge, the output end of the electric telescopic rod 312 can be controlled to contract, thereby driving the transmission plate 313 to move downward, and finally the transmission plate 313 drives the first driving mechanism 32 and the collecting box 34 to move downward, and then the sludge can be cleaned. After the sludge is cleaned, the collecting box 34 can be driven to move upward under the action of the electric telescopic rod 312. After the collecting box 34 is moved to a specified height, the sludge collected in the collecting box 34 can be processed.

[0047] In one embodiment of the present application, Figure 7 As shown, the positioning mechanism 37 includes a positioning rod 371 , a positioning plate 372 , a first pulling spring 373 , two positioning slots 374 and a push-pull plate 375 , wherein the positioning rod 371 slides through the collection box 34 , and the positioning plate 372 is installed on the top of the positioning rod 371 .

[0048] It should be noted that when the positioning rod 371 is engaged with one positioning groove 374, the sealing plate 35 does not seal the collection box 34. When the positioning rod 371 is engaged with the other positioning groove 374, the sealing plate 35 seals the collection box 34. The two positioning grooves 374 respectively position the sealing plate 35 when in the above state.

[0049] The first pulling spring 373 is sleeved on the positioning rod 371 , and one end of the first pulling spring 373 is connected to the positioning plate 372 , and the other end of the first pulling spring 373 is connected to the collection box 34 .

[0050] It should be noted that, in the initial state, the first pulling spring 373 has a continuous pulling force, which can keep one end of the positioning rod 371 continuously located in the positioning groove 374 when there is no external force acting on the push-pull plate 375 .

[0051] Two positioning grooves 374 are formed on the sealing plate 35 , and the two positioning grooves 374 and the positioning rod 371 are located on the same straight line. The push-pull plate 375 is installed on the sealing plate 35 .

[0052] In one embodiment of the present application, Figure 4 and Figure 7 As shown, one end of the positioning rod 371 and the positioning slot 374 are both arc-shaped.

[0053] Specifically, in actual use, the sealing plate 35 needs to be positioned after movement. In the initial state, the positioning groove 374 is clamped with one end of the positioning rod 371. When the bottom of the collection box 34 needs to be sealed, it is only necessary to directly push the push-pull plate 375 so that the push-pull plate 375 drives the sealing plate 35 to move. The movement of the sealing plate 35 will drive the positioning groove 374 to move. When the positioning groove 374 moves, it will squeeze the positioning rod 371, causing the positioning rod 371 to move upward. When the other positioning groove 374 moves to the top of the positioning rod 371, under the action of the first pulling spring 373, the positioning rod 371 enters the positioning groove 374 to complete the positioning of the sealing plate 35 after movement.

[0054] In one embodiment of the present application, Figure 6 and Figure 7 As shown, the cleaning mechanism 38 includes a reciprocating plate 381, a plurality of second scrapers 382, ​​a second pulling spring 383, a transmission rod 384, a push spring 385, a second driving mechanism 386, a pressing plate 387, a reciprocating groove 388 and a pulling rope 389, wherein the reciprocating plate 381 is slidably arranged in the collection box 34. The plurality of second scrapers 382 are mounted on the bottom surface of the reciprocating plate 381, and the second scrapers 382 are triangular. The second pulling spring 383 is mounted on one end of the reciprocating plate 381.

[0055] It should be noted that in order to prevent the second pulling spring 383 from affecting the up and down movement of the reciprocating plate 381, a movable plate that can slide up and down needs to be installed at one end of the reciprocating plate 381. The reciprocating plate 381 is connected to one end of the second pulling spring 383 through the movable plate, so that the reciprocating plate 381 is not affected by the second pulling spring 383.

[0056] The transmission rod 384 is installed on the reciprocating plate 381. The push spring 385 is sleeved on the transmission rod 384, and the push spring 385 is located between the reciprocating plate 381 and the collection box 34.

[0057] It should be noted that during use, the push spring 385 needs to follow the movement of the transmission rod 384. Therefore, a pad can be added to the top of the push spring 385, and the pad and the collection box 34 can slide against each other to avoid the push spring 385 sliding directly. The poor follow-up performance of the push spring 385 will affect the movement of the transmission rod 384.

[0058] The second driving mechanism 386 is installed on the collecting box 34 , and the second driving mechanism 386 and the transmission rod 384 are located on the same straight line.

[0059] It should be noted that the second driving mechanism 386 is a motor, which is used to drive the extrusion disk 387 to rotate when in use.

[0060] The extrusion plate 387 is mounted on the rotating shaft of the second driving mechanism 386, the reciprocating groove 388 is opened in the collection box 34, and the transmission rod 384 is slidably arranged in the reciprocating groove 388. One end of the pulling rope 389 is mounted on the reciprocating plate 381, and the other end of the pulling rope 389 is mounted on one end of the sealing plate 35.

[0061] It should be noted that in the initial state, if the sealing plate 35 does not seal the bottom of the collecting box 34, and the sealing plate 35 needs to be used to seal the bottom of the collecting box 34, the sealing plate 35 needs to be pushed. When the sealing plate 35 is pushed, the pulling rope 389 will be pulled, and then the pulling rope 389 will pull the reciprocating plate 381 upward, and the upward movement of the second scraper 382 will not affect the sealing of the sealing plate 35. At the same time, a larger storage space is provided under the reciprocating plate 381 for collecting sludge. When the sealing plate 35 is pulled open, the sealing plate 35 will no longer pull the pulling rope 389, and the reciprocating plate 381 will move downward under the push of the pushing spring 385, thereby driving the second scraper 382 to contact the bottom wall of the sedimentation tank 1, so as to facilitate the subsequent mud removal from the bottom wall.

[0062] Specifically, during the actual operation, sludge that is difficult to remove will remain on the inner wall of the sedimentation tank 1, and the number of cleaning times needs to be increased.

[0063] When the first driving mechanism 32 drives the collecting box 34 to clean the sedimentation tank 1, the extrusion plate 387 is driven to rotate through the output end of the second driving mechanism 386. When the extrusion plate 387 rotates, it pushes the transmission rod 384 to move. The movement of the transmission rod 384 drives the reciprocating plate 381 to move. The movement of the reciprocating plate 381 drives the second scraper 382 to move away from the second pulling spring 383.

[0064] When the reciprocating plate 381 moves, the second pulling spring 383 is pulled, so that the second pulling spring 383 is in an extended state. Then, when the extrusion plate 387 no longer squeezes the transmission rod 384, the second pulling spring 383 pulls the reciprocating plate 381, so that the reciprocating plate 381 drives the second scraper 382 to move in the direction of the second pulling spring 383. Finally, the rotation of the output end of the second driving mechanism 386 can drive the reciprocating movement of the second scraper 382, ​​so that the second scraper 382 removes mud from the sedimentation tank 1.

[0065] In one embodiment of the present application, Figure 5 As shown, the length of the reciprocating plate 381 is less than the length of the collection box 34 .

[0066] In one embodiment of the present application, Figure 8 As shown, a contraction groove is provided in the collection box 34, and one end of the second pulling spring 383 is installed in the contraction groove.

[0067] In one embodiment of the present application, Figure 4 As shown, a guide wheel is installed on the collection box 34, and the pulling rope 389 passes through the guide wheel and is connected to one end of the sealing plate 35.

[0068] It should be noted that the structure of the mud removal component 3 recorded in the above-mentioned document is only a structure for cleaning the bottom wall of the sedimentation tank 1. When the side wall of the sedimentation tank 1 needs to be cleaned, a collecting box 34 in contact with the side wall of the sedimentation tank 1 needs to be installed on the circumference of the rotating rod 33. The structures of the two collecting boxes 34 need to be packaged to be exactly the same. However, in order to make one end of the second scraper 382 completely contact with the side wall when cleaning the side wall, it is necessary to set the end of the second scraper 382 in contact with the sedimentation tank 1 to an arc, and the arcs of the two are the same, thereby ensuring that the second scraper 382 is in contact with the side wall of the sedimentation tank 1, so that the side wall of the sedimentation tank 1 can be mud removed during operation.

[0069] In summary, the mud removal device for industrial wastewater treatment in the embodiment of the present application improves the efficiency of mud removal by two methods: rotational mud removal and reciprocating mud removal. The two methods have different directions of mud removal, which can reduce the residual sludge and provide mud removal effect. At the same time, the sludge can be collected and processed after mud removal to prevent the sludge from mixing with the wastewater and requiring sedimentation again, which will lead to poor mud removal effect.
