Description

Technical Field

[0001] The invention relates to the technical field of sewage sludge treatment, and in particular to an integrated device based on sewage sludge separation treatment. Background Art

[0002] Since the sludge generated during the wastewater treatment process has a high moisture content, it is difficult to handle, utilize and transport. The sludge-wastewater separation equipment reduces its moisture content and volume by filtering the sludge, thereby reducing subsequent treatment costs.

[0003] However, in the prior art, there are many separation methods. No matter which separation method is used, it is first necessary to filter the entire filter screen to separate larger impurities, that is, to separate large particles of impurity sludge by screening with gravity. However, due to the mixing of sludge and particles, it has the characteristics of high adhesion, especially for wastewater with low mud content. The flowing sewage has traction on the sludge, and sewage sludge that needs to be separated continuously enters the filter screen, so that the sludge will gradually accumulate on the filter screen, causing some sludge to firmly adhere to the surface of the filter screen, forming a sediment layer that is difficult to remove. At present, many devices are equipped with structures such as scrapers and through-hole needles to avoid sludge clogging. When the through-hole needle is used to process the filter screen, the sludge residue on the surface of the needle will still re-attach to the mesh, causing the clogging problem to persist, thereby reducing the filtration efficiency of the subsequent filter screen, and as time goes by. As time goes by, the blockage will become more and more serious, resulting in an increased frequency of filter replacement and rising maintenance costs. At the same time, as the use time increases, sludge gradually accumulates on the filter to form a slope-like structure, which not only reduces the filtration area of ​​the filter, but also as time goes by, the sludge layer becomes thicker and thicker, making the handling and maintenance of the filter more difficult and shortening the service life of the filter. The design of the through-hole needle fails to effectively prevent the sludge from attaching again. In addition, the scraper is always located in a single position and is processed through unidirectional rotation, resulting in a single processing direction. The sewage sludge that continuously flows in from above can easily cause greater pressure on the scraper, which can easily cause the sludge to stick to the scraper surface. At the same time, the one-way scraper cannot effectively handle sludge with particularly strong viscosity and high water content, and the separated impurities are easily accumulated inside the equipment and cannot be handled in time, which will also cause the filtering effect of the filter to decline, making it difficult to completely solve the problem.

[0004] Therefore, an integrated device based on sewage sludge separation treatment is proposed to solve the problem of filter clogging. Summary of the invention

[0016] Beneficial effects of the present invention:

[0017] 1. The scraper blade receives power through the transmission part to move up and down, which can effectively break the adhesion between the sludge and the scraper blade surface, making it easier for the sludge to fall off the scraper blade, which not only improves the processing efficiency, but also reduces the accumulation of sludge on the scraper.

At the same time, with the sealing convex plate, the accumulated gravel can be automatically discharged in time when the accumulation is large, effectively reducing the adhesion of sludge on the scraper blade surface and improving the overall processing efficiency.

[0018] 2. The multi-leaf shaft rod is used to divide the sludge into batches first, and the arc plate is used to extend the time for different batches of sewage sludge to enter the filter cartridge. This can ensure that the amount of sludge input each time is appropriate, improve the uniformity and quality of sludge treatment, reduce downtime caused by equipment blockage or failure, and improve overall operating stability. At the same time, the treatment strategy can be flexibly adjusted according to changes in sludge volume to adapt to different treatment needs.

[0019] 3. The slag is stored above the sealing convex plate, and the scraper is used for multi-directional processing. At the same time, the sealing convex plate and the extrusion cone are combined to prevent impurities from randomly sticking and accumulating inside the filter cartridge, keep the inside of the suction equipment clean, and always ensure the filtering effect of the filter disc. The equipment can automatically adjust according to the accumulation of slag and processing needs, which can reduce the splashing of sludge and the generation of odor during the processing process, thereby improving the working environment of the operator.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figure 1-8, as an embodiment of the present invention, an integrated device based on sewage sludge separation treatment is provided, including a separator 1, and also including a suction device 2 arranged on one side of the separator 1, a filter cartridge 3 fixedly arranged on the top of the separator 1, a sealing plate 4 fixedly connected to the top of the filter cartridge 3, a feed piece 5 fixedly connected to the top of the sealing plate 4, a multi-leaf shaft rod 6 rotatably connected to the inside of the feed piece 5, a stripping extrusion piece 7 slidably connected to the inside of the filter cartridge 3, a filter piece 8 rotatably connected to the inside of the filter cartridge 3, a slag collection barrel 9 fixedly connected to the inside of the filter cartridge 3, a sealing convex plate 10 located inside the slag collection barrel 9, a spring telescopic rod 11 connected between the slag collection barrel 9 and the sealing convex plate 10, and a spring telescopic rod 11 fixedly connected to the filter cartridge 3, a spur gear 13 and a semi-transmission gear 14 fixedly connected to the output end of the drive motor 12, and a transmission member 15 rotatably connected to the inside of the filter cartridge 3, one end of the suction device 2 extends to the inside of the slag collecting cylinder 9, the stripping extrusion member 7 is located above the filter member 8, the filter member 8 is located above the slag collecting cylinder 9, the stripping extrusion member 7 does not contact the sealing convex plate 10, the spur gear 13 is meshed with the filter member 8, the semi-transmission gear 14 is meshed with the transmission member 15, one end of the transmission member 15 extends to the inside of the filter cartridge 3 and fits with the stripping extrusion member 7, when the slag above the sealing convex plate 10 reaches the set value, the stripping extrusion member 7 makes the top of the sealing convex plate 10 communicate with the slag collecting cylinder 9.

[0032] Reference Figure 1-3 The stripping extrusion member 7 includes a ring 71 slidably connected to the inside of the filter cartridge 3, a plurality of scrapers 72 arranged at equal angles and fixedly connected to the ring 71, and an extrusion cone 73 fixedly connected between the plurality of scrapers 72, a limiting telescopic rod connected between the ring 71 and the filter cartridge 3, the ring 71 is fixed to the inside of the filter cartridge 3 through the limiting telescopic rod, the limiting telescopic rod is a conventional existing structure, similar to the spring telescopic rod 11 without a spring inside, the ring 71 is fitted with the transmission member 15, and the transmission member 15 will squeeze the ring 71 when it rotates, so that the ring 71 moves up and down, the scraper 72 is located above the filter element 8, and the scraper 72 is used to process the surface of the filter element 8.

[0033] Reference Figure 1-7 A feed port 51 is provided inside the feed member 5 and is located at the right half of the multi-leaf shaft 6 . A discharge port 52 is provided at the bottom of the feed port 51 and an arc plate 53 is provided inside the discharge port 52 and is located directly below the feed port 51 .

[0034] Specifically, the sludge sewage will first enter the interior of the feed piece 5, and reach between the multi-leaf shaft 6 and the feed piece 5 through the feed port 51. At this time, the sewage sludge will be located between the two blades of the multi-leaf shaft 6. At this time, the sewage sludge falls on the upper right side of the multi-leaf shaft 6 to create pressure, causing the multi-leaf shaft 6 to rotate, and the multi-leaf shaft 6 is used to form multiple spaces for inputting sewage sludge in batches. The arc plate 53 arranged inside the discharge port 52 will close a part of the discharge port 52, so that the area of ​​the multi-leaf shaft 6 with sewage sludge cannot move down to the interior of the filter cartridge 3 without crossing the arc plate 53. When the sewage sludge conveying amount and water content are both large, the impact on the multi-leaf shaft 6 is large, and the multi-leaf shaft 6 will rotate faster, and the arc plate 53 is used to extend the time for different batches of sewage sludge to enter the interior of the filter cartridge 3.

[0035] Reference Figure 2-5 The sealing convex plate 10 is located below the filter element 8 , and the extrusion cone 73 is located directly above the sealing convex plate 10 and the two do not contact each other. The outer diameter of the extrusion cone 73 is inclined upward in a direction gradually approaching the center of the circle, and the middle part of the filter element 8 is closed by the sealing convex plate 10 .

[0036] Specifically, there is a gap between the extrusion cone 73 and the sealing convex plate 10, and the extrusion cone 73 cannot contact the sealing convex plate 10, and the extrusion cone 73 will move up and down with the collar 71. When the extrusion cone 73 moves up, the gravel will reach the top of the sealing convex plate 10. With the extrusion of the extrusion cone 73 moving downward and the continuous accumulation of gravel, the extrusion cone 73 can use the gravel as an intermediate medium. At this time, the downward movement of the extrusion cone 73 can squeeze the sealing convex plate 10 downward. Due to the pressure relief above the movement of the sealing convex plate 10, the gravel will quickly enter the interior of the slag collecting barrel 9. At this time, regardless of whether the extrusion cone 73 moves up or not, the sealing convex plate 10 will be quickly and automatically closed due to the reduction of the medium between the extrusion cone 73 and the sealing convex plate 10. At the same time, since the extrusion cone 73 will fit the filter element 8, the external sludge and sewage cannot reach the top of the sealing convex plate 10, let alone the interior of the slag collecting barrel 9.

[0037] In addition, when gravel or sludge accumulates above the extrusion cone 73, the extrusion cone 73 is moved up and down, and the inclination angle of the extrusion cone 73 is used to prevent the gravel or sludge from accumulating above the extrusion cone 73.

[0038] Reference Figure 2-6A fixing rod 31 is provided inside the filter cartridge 3, and the fixing rod 31 is fixedly connected to the slag collecting barrel 9, and the slag collecting barrel 9 is rotatably connected to the bottom of the filter element 8, and the slag collecting barrel 9 is connected to the filter element 8, and a sealing convex plate 10 is provided between the filter element 8 and the slag collecting barrel 9. At this time, the slag collecting barrel 9 is in a sealed state, and the sewage sludge filtered by the filter element 8 cannot enter the interior of the sealing convex plate 10. The filter element 8 will rotate after being driven, and the slag collecting barrel 9 will be fixed by the fixing rod 31. The slag collecting barrel 9 will not rotate with the filter element 8, thereby ensuring that the slag collecting barrel 9 is used to store slag gravel.

[0039] Reference Figure 2-6 The filter element 8 includes a filter disc 81 rotatably connected to the inside of the filter cartridge 3, a force-bearing gear 82 arranged on the outside of the filter disc 81, and a slag leakage port 83 opened at the center of the filter disc 81. The outer diameter of the filter disc 81 is inclined downward in a direction gradually approaching the center of the circle, so that the filter disc 81 forms a funnel shape, and the slag, sewage and sludge will move to the slag leakage port 83, but the downward movement of the extrusion cone 73 will squeeze and move the sewage and sludge, while the slag with larger weight particles will accumulate. The spring inside the spring telescopic rod 11 is a strong spring, and at the same time, the diameter of the sealing convex plate 10 is larger than the diameter of the slag leakage port 83 to ensure the sealing of the slag leakage port 83 and the speed of the sealing convex plate 10 moving back. The force-bearing gear 82 is meshed with the spur gear 13. The spur gear 13 is driven by the drive motor 12 and is transmitted to the force-bearing gear 82, so that the filter disc 81 rotates. In addition, the drive motor 12 can rotate evenly and slowly to avoid large friction.

[0040] Reference Figure 1-8 The transmission member 15 includes a helical gear connecting rod wheel 151 rotatably connected to the inside of the filter cartridge 3, a cam 152 fixedly connected to one end of the helical gear connecting rod wheel 151, the helical gear connecting rod wheel 151 meshes with the semi-transmission gear 14, the gear transmission ratio between the semi-transmission gear 14 and the helical gear connecting rod wheel 151 is two to one, the cam 152 fits with the collar 71, the semi-transmission gear 14 will rotate after being driven by the driving motor 12, the semi-transmission gear 14 will be transmitted to the helical gear connecting rod wheel 151, and the helical gear connecting rod wheel 151 will pass through after being driven The transmission is transmitted to the collar 71 through the cam 152. In order to prevent the collar 71 from moving up and down for a long time, the gear transmission ratio of the semi-transmission gear 14 and the helical connecting rod wheel 151 is two to one, so that the collar 71 moves up and down intermittently, so that the position of the scraper 72 is divided into contact with the surface of the filter disc 81 and above the filter disc 81, which reduces the sludge residue and reduces the direct contact time between the scraper and the sludge, ensuring that the sludge on the scraper 72 can be effectively treated, and the scraper 72 can also treat the sludge on the surface of the filter disc 81.

[0041] Reference Figure 1-8The separator 1 includes an extrusion filter 101, and a guide plate 102 and a mounting frame 103 fixedly connected to the top of the extrusion filter 101. The filter cartridge 3 is fixedly connected to the top of the mounting frame 103, all of which are existing equipment, and the suction device 2 is also an existing equipment, and the equipment has conventional valves and other structures.

[0042] Reference Figure 1-8 The interior of the filter disc 81 is divided into a filter hole area 811 and a closed area 812. The filter hole area 811 is partially used for filtering, while the closed area 812 can store gravel. The diameter of the extrusion cone 73 is larger than the diameter of the closed area 812, thereby effectively covering the closed area 812. At the same time, the extrusion cone 73 can contact the filter hole area 811 to prevent the upper part of the sealing convex plate 10 from being closed, thereby avoiding the use of sewage as a medium to drive the sealing convex plate 10 when the extrusion cone 73 squeezes sewage. The extrusion cone 73 is located directly above the closed area 812, ensuring that the extrusion cone 73 effectively squeezes the gravel accumulated above the sealing convex plate 10.

[0043] Reference Figure 1-8 One end of the spring telescopic rod 11 is located at the center of the slag collecting cylinder 9, and the other end of the spring telescopic rod 11 is located at the center of the sealing convex plate 10. The outer diameter of the sealing convex plate 10 is inclined upward in a direction gradually approaching the center of the circle, so that the slag and gravel are first accumulated around the sealing convex plate 10, and the bottom surface of the extrusion cone 73 is horizontal. The extrusion cone 73 is used to squeeze and accumulate the slag and gravel above the sealing convex plate 10, so that the density of the accumulated slag and gravel increases.

[0044] The working principle of the present invention is as follows: when the sewage sludge passes into the interior of the feed member 5, it will fall into the interior of the multi-leaf shaft 6 through the feed port 51. Since the feed port 51 is located at the right half of the multi-leaf shaft 6, the sewage sludge will impact the multi-leaf shaft 6, causing the multi-leaf shaft 6 to rotate. The sewage sludge above the multi-leaf shaft 6 will move with the rotation of the multi-leaf shaft 6. When the multi-leaf shaft 6 passes over the arc plate 53, the sewage sludge will quickly enter the interior of the filter cartridge 3 from the discharge port 52, thereby achieving a temporary but batch processing effect. The sewage sludge entering the filter cartridge 3 will first directly reach the top of the filter disc 81, and the larger particles in the sewage sludge will be blocked by the filter hole area 811 of the filter disc 81 and At the top, the driving motor 12 drives the spur gear 13 and the semi-transmission gear 14 to rotate at the same time. The spur gear 13 directly transmits the force-bearing gear 82 to rotate the filter disc 81, and the slag outlet 83 is in a closed state with the sealing convex plate 10 at this time. When the semi-transmission gear 14 rotates, it intermittently drives the helical connecting rod wheel 151 to rotate. When the helical connecting rod wheel 151 rotates, it drives the cam 152 to rotate, so that the cam 152 squeezes the collar 71. Therefore, the collar 71 is in an up and down moving state, and the collar 71 does not rotate, so that when the collar 71 is at the bottom, the scraper 72 contacts the inside of the filter disc 81, and the scraper 72 is used to peel off the slag on the surface of the filter disc 81, and the peeled slag will accumulate and slide down. Since the collar 71 is in an up and down moving state, the gravel will accumulate toward the position of the slag leakage port 83 with the inclination angle of the filter disc 81, and the collar 71 will also drive the extrusion cone 73 to move synchronously when moving up and down, and the extrusion cone 73 will continuously squeeze the accumulated gravel and sewage, and the sewage will be discharged through the filter hole area 811 after being squeezed, while the gravel will continue to accumulate and gradually become dense. Since the extrusion cone 73 continues to move up and down with the collar 71, when the extrusion cone 73 moves up, the gravel will move toward the position of the slag leakage port 83, and when the extrusion cone 73 moves down, the gravel will be squeezed. When the accumulation amount of gravel is greater than the distance between the extrusion cone 73 and the sealing convex plate 10, and it is denser, it can serve as a medium, so that when the extrusion cone 73 moves downward, it will squeeze the gravel, and the gravel will be transmitted to the sealing convex plate The sealing convex plate 10 moves downward and compresses the spring telescopic rod 11 at the same time. At this time, the sealing convex plate 10 is no longer in contact with the filter disc 81, and the slag leakage port 83 is briefly opened. The slag and gravel above the sealing convex plate 10 will quickly release pressure and move down to the inside of the slag collecting tube 9. Once the slag and gravel are reduced, the spring telescopic rod 11 will rebound quickly, so that the sealing convex plate 10 will close the slag leakage port 83 again, so that the accumulated slag and gravel can be processed in time to ensure that the slag and gravel are always within a controllable range. At the same time, the collar 71 drives the scraper 72 to move up and down, so that the sludge on the surface of the scraper 72 can be effectively removed, and the scraper 72 will not always contact with the filter disc 81. The filter disc 81 is driven to rotate to intermittently contact the scraper 72, so that the surface of the continuously rotating filter disc 81 is intermittently processed by the scraper 72.The sewage sludge passing through the filter plate 81 will be guided by the guide plate 102, and further processed by squeezing through the squeezing filter 101, while the slag inside the slag collecting tube 9 can be sucked by the suction device 2.
