Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment equipment, in particular to a sand medium high-efficiency sedimentation tank for water treatment. BACKGROUND

[0002] The sand medium high-efficiency sedimentation tank, also known as a micro-sand sedimentation tank or a heavy medium sedimentation tank, is a water treatment equipment that improves sedimentation efficiency with sand medium. Its operation process includes multiple steps: first, a coagulant is added in the coagulation tank to make the suspended solids and colloidal particles lose stability; then, micro-sand is added in the injection tank, and a flocculant is added in the maturation tank. The destabilized impurity particles will form dense alunite flowers with the micro-sand as the flocculation nucleus through the bridging adsorption of high molecular chains and the deposition net capture of micro-sand particles. These alunite flowers realize efficient separation in the inclined tube sedimentation tank, and the mud and sand at the bottom enter the hydrocyclone through the reflux system. After separation, the micro-sand can be recycled to the system for reuse, completing the entire water treatment cycle.

[0003] The bottom of the traditional box-type high-efficiency sedimentation tank is usually provided with a conical box (i.e. a sludge hopper), which has the core function of accumulating sludge and sundries generated by sedimentation. In conventional cleaning operations, the sludge on the inner wall of the sedimentation tank is generally scraped off and collected into the conical box by a scraper device, and then the sludge in the box is pumped out by a sludge pump. However, this cleaning method has obvious limitations: the scraper device can only act on the inner wall of the sedimentation tank, and the conical sludge hopper with a fixed shape cannot be completely cleaned by the scraper. This results in a thick layer of sludge residue remaining on the inner wall of the sludge hopper after the cleaning operation is completed. If manual cleaning is used, it not only consumes a lot of manpower and time, but also consumes a large amount of water resources if high-pressure water washing is used. In addition, the cleaning time is also relatively long, which not only affects the treatment efficiency but also causes resource waste. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a sand medium high-efficiency sedimentation tank for water treatment, which solves the problems of the conventional box-type high-efficiency sedimentation tank, such as the scraper only being able to clean the inner wall, the conical sludge hopper being prone to leaving sludge, manual cleaning consuming a lot of manpower and time, high-pressure water washing consuming a lot of water, and high energy consumption for cleaning and easy penetration of sewage into the equipment causing failure.

[0010] Further, a limit groove is formed at the inside of the fixed shaft, and the outer surface of the rotating rod is longitudinally and slidingly connected to the inside of the limit groove, and the rotating rod and the limit groove are both hexagonal.

[0011] Further, the end of the fixed shaft extends into the interior of the mounting groove, a sealing sleeve is sleeved on the outer surface of the fixed shaft, and the fixed shaft is rotationally connected in the interior of the sludge collecting tank through the sealing sleeve.

[0017] (Three) beneficial effects

[0018] The present application has the following beneficial effects:

[0019] (1) The sand medium high-efficiency sedimentation tank for water treatment breaks through the limitation that the traditional scraper can only clean the inner wall of the sedimentation tank and cannot completely clean the conical sludge hopper through the synergistic effect of the reciprocating driving assembly and the sealing sludge cleaning assembly. The reciprocating driving assembly can drive the sealing sludge cleaning assembly to longitudinally reciprocate in the conical sludge collecting groove, and the air bag in the sealing sludge cleaning assembly can tightly attach to the inner wall of the conical groove under the action of the electric telescopic rod, so as to realize comprehensive wiping of the groove wall through cooperation and rotation friction. The disc-shaped brush at the bottom can simultaneously clean the bottom wall of the conical sludge collecting groove. The double sludge cleaning structure effectively avoids the adhesion and residue of sludge on the groove wall and groove bottom. Compared with manual cleaning or high-pressure water washing, the sludge cleaning coverage is improved, and the residue problem of the traditional cleaning method is completely solved.

[0020] (2), compared with the traditional high-pressure water washing needs to consume a large amount of water resources, artificial cleaning time-consuming and laborious disadvantages, the sedimentation tank of the sand medium for water treatment does not need to consume a large amount of clean water, only through the rotation and sliding of the mechanical structure can complete efficient cleaning, the water consumption of single cleaning is greatly reduced compared with the traditional high-pressure water washing, at the same time, the reciprocating drive assembly is driven by a single drive motor, and the double action of "rotation + reciprocating sliding" is realized through the pulley transmission, without additional power source, the energy consumption is lower, and the cleaning process is automatic operation without manual intervention, the single cleaning time is shortened compared with manual cleaning, which greatly improves the water treatment efficiency and reduces the labor and resource cost.

[0021] (3), the sand medium high-efficiency sedimentation tank for water treatment, the sealing and cleaning assembly is provided with a double sealing structure of a rubber sealing sleeve and a sealing sleeve outside the fixed shaft, which can effectively prevent the sewage and sludge in the conical sludge collecting tank from penetrating into the installation groove, avoid the reciprocating drive assembly from malfunctioning due to sewage immersion, prolong the service life of the equipment, at the same time, the air bag is made of wear-resistant material and has longitudinal grooves on the outer surface, which not only enhances the friction cleaning effect with the conical groove wall, but also improves the wear resistance of the air bag, reduces the replacement frequency of the vulnerable parts; in addition, the upper surface of the upper fixed disc is designed as a cone, which can avoid the accumulation of sludge on its surface, further guaranteeing the smoothness of the cleaning process and the stability of the equipment operation.

[0022] Of course, it is not necessary to achieve all the advantages described above when implementing any product of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0038] Specifically, the sealing and sludge cleaning assembly 7 comprises a fixed shaft 73 rotatably connected at the inside center of the sliding disc 68 through a locating bearing, the outer surface of the fixed shaft 73 is sealingly and slidingly sleeved with a rubber sealing sleeve 77, the outer surface of the rubber sealing sleeve 77 is fixedly sleeved with a lower fixed disc 71, the bottom of the lower fixed disc 71 is fixedly connected with a disc-shaped brush 72, the top of the fixed shaft 73 is fixedly connected with an upper fixed disc 75, the surface of the lower fixed disc 71 is fixedly installed with an electric telescopic rod 74, the output end of the electric telescopic rod 74 is fixedly connected to the bottom of the upper fixed disc 75, the outer surface of the fixed shaft 73 is sleeved with an air bag 76, the top of the air bag 76 is fixedly connected to the bottom of the upper fixed disc 75, the bottom of the air bag 76 is fixedly connected to the top of the lower fixed disc 71, and the outer surface of the rotating rod 62 is inserted into the inside of the fixed shaft 73.

[0040] Specifically, the inner part of the fixed shaft 73 is provided with a limiting groove 731, and the outer surface of the rotating rod 62 is longitudinally and slidingly connected in the inner part of the limiting groove 731, and both the rotating rod 62 and the limiting groove 731 are hexagonal.

[0041] In this embodiment, the inner part of the fixed shaft 73 is provided with a hexagonal limiting groove 731, and the rotating rod 62 is designed as a matching hexagonal structure, and the sliding connection of the two can not only ensure that the rotating rod 62 stably transmits torque to drive the fixed shaft 73 to rotate synchronously, thereby improving the transmission efficiency, but also meet the requirement that the fixed shaft 73 moves longitudinally and reciprocally with the sliding disc 68, without affecting the power transmission, thereby ensuring the coherent action of the sealing and cleaning assembly 7.

[0042] Specifically, the end of the fixed shaft 73 extends into the installation groove 5, and a sealing sleeve is sleeved on the outer surface of the fixed shaft 73, and the fixed shaft 73 is sealingly and rotatably connected in the inner part of the collecting tank 2 through the sealing sleeve, and the outer surface of the sealing sleeve is fixedly connected in the inner part of the collecting tank 2.

[0044] Specifically, the top of the conical collecting tank 4 has a larger diameter than the bottom, and the bottom of the conical collecting tank 4 is in communication with the inner part of the drain pipe 3.

[0045] In this embodiment, the top of the conical collecting tank 4 has a larger diameter than the bottom, and the settled sludge can quickly collect at the bottom of the tank under the action of gravity, thereby reducing the residence time of the sludge on the tank wall and reducing the difficulty of sludge adhesion; at the same time, this structure cooperates with the longitudinal reciprocating action of the sealing and cleaning assembly 7, can guide the sludge to move faster to the drain pipe 3, improve the sludge discharge efficiency, and shorten the single sludge emptying time.

[0046] Specifically, the sliding disc 68 is longitudinally and slidingly connected in the inner part of the installation groove 5 through the limiting rod 63, and the output end of the driving motor 61 extends into the inner part of the installation groove 5.

[0047] In this embodiment, the sliding disc 68 is slidingly connected with the limiting rod 63 on the inner wall of the installation groove 5 through the limiting hole 683 formed on the surface of the sliding disc 68, and the limiting rod 63 can accurately limit the sliding track of the sliding disc 68, thereby avoiding the deviation and shaking of the sliding disc 68 during the longitudinal reciprocating process, ensuring the stable movement of the sealing and cleaning assembly 7, controlling the cleaning action error within a certain range, and ensuring that the four areas of the conical collecting tank 4 can be effectively cleaned.

[0048] Specifically, the upper surface of the upper fixed disc 75 is conical, and the air bag 76 is made of wear-resistant material, and the outer surface of the air bag 76 is provided with longitudinal grooves.

[0049] In the embodiment, the upper surface of the upper fixed disc 75 is designed to be conical. During the cleaning process, the sludge falling on the surface of the upper fixed disc 75 can slide along the conical surface to the conical sludge collecting groove 4, avoiding the accumulation of sludge on the surface to form secondary pollution, reducing the cleaning and maintenance workload of the upper fixed disc 75, shortening the time consumption of single cleaning process, and improving the overall water treatment efficiency.

[0050] Specifically, the bottom of the disc-shaped brush 72 is attached to the bottom wall of the conical sludge collecting groove 4, the air bag 76 is annular, and the diameter of the air bag 76 is much larger than the outer diameter of the fixed shaft 73.

[0051] In the embodiment, the diameter of the air bag 76 is much larger than the outer diameter of the fixed shaft 73, which can avoid the extrusion of the disc-shaped brush 72 on the fixed shaft 73 when the disc-shaped brush 72 is deformed, and affect the normal sliding of the lower fixed disc 71.

[0054] In use, the sludge deposited in the box-type sedimentation tank main body 1 will accumulate in the conical sludge collecting groove 4. When the sludge needs to be cleaned, the electric telescopic rod 74 is started to be shortened. At this time, the lower fixed disc 71 slides towards the upper fixed disc 75, and the air bag 76 is extruded by the lower fixed disc 71, so that the air bag 76 deforms, and the outer diameter of the air bag 76 increases and abuts against the inner wall of the conical sludge collecting groove 4. Then the driving motor 61 is started, the driving motor 61 drives the rotating rod 62 to rotate, the rotating rod 62 drives the fixed shaft 73 to rotate through the clamping of the limiting groove 731, the fixed shaft 73 drives the air bag 76 and the lower fixed disc 71 to rotate through the upper fixed disc 75, and the sludge on the inner wall of the conical sludge collecting groove 4 is rubbed by the rotation of the air bag 76, so that the sludge on the inner wall of the conical sludge collecting groove 4 is quickly separated.

[0055] When the driving motor 61 drives the rotating rod 62 to rotate, the rotating rod 62 drives the driven pulley 65 to rotate through the driving pulley 67 and the toothed belt 66, and the driven pulley 65 drives the sliding disc 68 to slide longitudinally in the installation groove 5 through the connection of the reciprocating threaded rod 64 and the positioning column 682, when the sliding disc 68 slides, the fixed shaft 73 slides up and down through the positioning bearing, when the fixed shaft 73 slides up and down, the upper fixed disc 75 and the air bag 76 slide up and down, realizing the comprehensive cleaning of the inner wall of the conical sewage collecting tank 4, when the disc-shaped brush 72 slides to the bottom end of the conical sewage collecting tank 4, the friction of the conical sewage collecting tank 4 bottom wall is realized through the rotation of the disc-shaped brush 72, which can clean the bottom of the conical sewage collecting tank 4, and finally, after cleaning is completed, the electric telescopic rod 74 is started to extend, so that the lower fixed disc 71 slides away from the upper fixed disc 75, and the air bag 76 is reset to the initial state, at this time, the air bag 76 can be driven to rotate through the continuous starting of the driving motor 61, and due to the centrifugal force, the sludge on the surface of the air bag 76 can be thrown to the inner wall of the conical sewage collecting tank 4, and then the cleaning water in the box-type sedimentation tank main body 1 enters the conical sewage collecting tank 4, so that the sewage is discharged from the sewage pipe 3, at this time, the cleaning of the inside of the sewage collecting tank 2 is completed.
