Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a scum collection device for wastewater treatment ponds. Background Technology

[0002] Industrial wastewater treatment requires wastewater treatment ponds. During the treatment process, a layer of scum forms on the surface of the water. This scum needs to be removed and collected. Collecting the scum effectively removes impurities from the water surface, ensuring the smooth operation of the wastewater treatment process, improving effluent quality, and reducing environmental pollution. Therefore, scum collection is an indispensable part of the wastewater treatment process.

[0003] Currently, while using scraper cleaning mechanisms to remove scum from wastewater treatment ponds is a common practice in existing technologies, this method has several limitations. First, scraper cleaning mechanisms are typically bulky, resulting in high manufacturing costs and a lack of flexibility, making them inconvenient to move between different wastewater treatment ponds. For sites with multiple wastewater treatment ponds, multiple units need to be purchased, which undoubtedly increases the economic burden and management complexity.

[0004] Furthermore, these large pieces of equipment occupy a significant amount of space when not in use, posing challenges to site planning. Even more problematic is the fact that different sized scrapers often need to be customized for different sizes of wastewater treatment tanks, which not only increases costs but also limits the equipment's versatility.

[0005] More importantly, scrapers tend to accumulate a large amount of scum during use. If not cleaned in time, this scum will not only affect the scraping efficiency of the scraper, but may also corrode the scraper surface due to long-term accumulation, shortening the service life of the equipment. Cleaning scum from scrapers is often time-consuming and labor-intensive, increasing maintenance costs and workload.

[0006] Therefore, it is of great significance to study a new scum collection device for sewage treatment ponds to solve the above problems. Summary of the Invention

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0009] Therefore, the technical problem to be solved by the present invention is that the scraper cleaning mechanism in the prior art is usually bulky, not only with high manufacturing cost, but also lacking flexibility and inconvenient to move between different sewage treatment tanks. In addition, it occupies a lot of space when not in use, and when facing sewage treatment tanks of different sizes, it is often necessary to customize scrapers of different sizes. Moreover, a large amount of scum easily adheres to the scraper during use. If it is not cleaned in time, the scum will not only affect the scraping efficiency of the scraper, but may also cause corrosion to the scraper surface due to long-term accumulation, thus shortening the service life of the equipment.

[0012] The scum interception mechanism includes a guide rail, which is located below the bidirectional hydraulic adjustment component. A vibration component is mounted below the guide rail, and an adjustable interception component is connected below the vibration component.

[0013] The bidirectional hydraulic adjustment assembly includes two piston housings, with a guide rail fixedly connected to the bottom of the two piston housings. The front and rear sides of the opposite surfaces of the two piston housings are connected by a pipe. A piston rod is provided inside each of the two piston housings, and an operating rod is inserted through the piston rod. A sealing disc is fixedly connected to one end of the operating rod. The sealing disc overlaps with the piston rod, and multiple liquid holes are provided on both the sealing disc and the piston rod.

[0014] As a further embodiment of the present invention: the piston rod extends out of the piston shell and is fixedly connected to the movable plate, the operating rod also extends out of the movable plate and is fixedly connected to the operating disk, the movable plate has two fixing holes, the operating disk is provided with a pin structure, and one end of the pin structure extends into the fixing hole.

[0015] As a further aspect of the present invention: the longitudinal adjustment assembly includes a first telescopic frame and a side cavity, the four ends of the first telescopic frame are respectively hinged to the piston shell, the side cavity, the movable plate and the side, and a first telescopic adjustment structure is fixedly connected to the lower part of the side, and an auxiliary wheel is fixedly connected to the bottom end of the first telescopic adjustment structure.

[0016] As a further aspect of the present invention: the longitudinal adjustment assembly includes a first telescopic frame and a side cavity, the four ends of the first telescopic frame are respectively hinged to the piston shell, the side cavity, the movable plate and the side, and a first telescopic adjustment structure is fixedly connected to the lower part of the side, and an auxiliary wheel is fixedly connected to the bottom end of the first telescopic adjustment structure.

[0017] As a further aspect of the present invention, a handle is fixedly connected to the top of the piston housing.

[0018] As a further aspect of the present invention: the positioning component includes a second telescopic adjustment structure, the second telescopic adjustment structure is fixedly connected to the lower part of the side cavity, a stud is fixedly connected to the bottom end of the second telescopic adjustment structure, a movable wheel is fixedly connected to the bottom end of the stud, a threaded sleeve is threaded onto the stud, and a positioning disc is fixedly connected to the outside of the threaded sleeve.

[0019] As a further aspect of the present invention: the vibration assembly includes two slide rails, which slide in a guide rail, and a spring is fixedly connected between the two guide rails. One of the slide rails is fixedly connected to an electro-hydraulic rod, and the first electro-hydraulic rod is installed in the guide rail.

[0020] As a further embodiment of the present invention: a bracket is fixedly connected to the lower part of one of the slide rails, a motor is fixedly mounted on the bracket, a petal cam is fixedly connected to the output shaft of the motor, a pulley is attached to one side of the petal cam, and the pulley is fixedly connected to another slide rail.

[0021] As a further aspect of the present invention: the adjustable interception component includes a second telescopic frame, the lower part of which is hinged to a foldable plate, and both ends of the second telescopic frame are respectively hinged to another slide rail and a support block, with the support block fixedly connected to the lower part of the guide rail.

[0022] As a further aspect of the present invention: the foldable plate is composed of multiple plates, and the multiple plates are connected by hinges.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This scum collection device for sewage treatment ponds extends and positions a single longitudinal adjustment component to the edge of the sewage pond, maintaining overall stability. Simultaneously, an electric hydraulic rod controls the second telescopic frame to extend and retract a foldable plate, thus adjusting the scum collection area. Pulling the side retracts the first telescopic frame, which in turn drives the adjustable interception component to collect scum from the sewage surface. The foldable plate has a V-shaped structure, enhancing the scum collection effect. This method utilizes the telescopic adjustability of the first and second telescopic frames to accommodate sewage ponds of different sizes. It also allows for retraction for storage, reducing space occupation. Furthermore, the use of casters facilitates easy transfer between sewage ponds, greatly improving versatility and effectively reducing costs.

[0025] 2. The scum collection device for this sewage treatment tank is driven by a motor to rotate a petal cam. The petal cam squeezes the pulley to move, the pulley drives the slide rail to move, and causes the spring to deform. At the same time, after the petal cam disengages from the concave surface of the petal cam, the spring deforms and can drive the slide rail to move. The petal cam, together with the spring, causes the slide rail and the second telescopic frame to vibrate. The second telescopic frame drives the foldable plate to reciprocate. The vibration of the foldable plate can shake off the attached scum and avoid scum residue. At the same time, it can be used with a water gun to clean it more thoroughly.

[0026] 3. The scum collection device for this sewage treatment tank uses a longitudinal adjustment component to drive the adjustable interception component to move, thereby pulling the scum on the surface of the sewage tank to one side and smoothly bringing the scum into the collection tank. At this time, the vibration component drives the adjustable interception component to reciprocate and extend, allowing the adjustable interception component to adjust the swing angle, which facilitates the use of water guns to reduce cleaning dead spots, improve the cleaning effect, and effectively reduce maintenance costs and workload.

[0045] Example 1

[0046] like Figures 1-10 and Figure 12 As shown, the present invention provides a technical solution: a scum collection device for a sewage treatment pond, including an adjusting mechanism 100, on which a scum interception mechanism 200 is mounted;

[0047] The adjustment mechanism 100 includes a bidirectional hydraulic adjustment assembly 103. Both sides of the bidirectional hydraulic adjustment assembly 103 are connected to longitudinal adjustment assemblies 101. Each longitudinal adjustment assembly 101 includes a first telescopic frame 1011 and a side cavity 1012. The four ends of the first telescopic frame 1011 are respectively hinged to the piston housing 1031, the side cavity 1012, the movable plate 1037, and the side edge 1013. A first telescopic adjustment structure 1014 is fixedly connected to the lower part of the side edge 1013. An auxiliary wheel 1015 is fixedly connected to the bottom end of the first telescopic adjustment structure 1014. Through the auxiliary wheel 1015... The auxiliary wheel 1015 supports the first telescopic adjustment structure 1014 and reduces movement resistance, facilitating the extension operation of the telescopic rod 1016. The telescopic rod 1016 is housed inside the side cavity 1012. The telescopic nature of the telescopic rod 1016 facilitates control of the extension and retraction of the first telescopic frame 1011. The telescopic rod 1016 extends from the side cavity 1012 and is fixedly connected to the side edge 1013. Two positioning components 102 are mounted below the longitudinal adjustment assembly 101. Each positioning component 102 includes a second telescopic adjustment structure. 1021, through the vertical adjustability of the second telescopic adjustment structure 1021 and the first telescopic adjustment structure 1014, the overall height can be adjusted, facilitating the placement of the entire structure beside the sewage tank. Simultaneously, by adjusting the overall vertical position, the foldable plate 2011 can be easily adjusted into the sewage tank, thereby facilitating the removal of scum from the sewage tank. The second telescopic adjustment structure 1021 is fixedly connected to the lower part of the side cavity 1012, and a stud 1022 is fixedly connected to the bottom end of the second telescopic adjustment structure 1021. A movable [device / mechanism] is fixedly connected to the bottom end of the stud 1022. The movable wheel 1025 assists in the overall movement and makes the operation more convenient and easy to transfer. The stud 1022 is threadedly connected to the sleeve 1023. The sleeve 1023 is threadedly connected to the stud 1022, so that the vertical position of the positioning plate 1024 can be adjusted. When the positioning plate 1024 moves upward, the movable wheel 1025 can move smoothly. When the positioning plate 1024 touches the ground downward, the overall stability can be maintained. The positioning plate 1024 is fixedly connected to the outside of the sleeve 1023.

[0048] The scum interception mechanism 200 includes a guide rail 202, which is located below the bidirectional hydraulic adjustment component 103. A vibration component 203 is mounted below the guide rail 202, and an adjustable interception component 201 is connected below the vibration component 203. The adjustable interception component 201 includes a second telescopic frame 2012, which is telescopic. A foldable plate 2011, composed of multiple plates connected by hinges, allows the plates to be bent, thereby enabling the second telescopic frame 2012 to... 2. With the foldable plate 2011, the width of scum removal can be easily adjusted, making it suitable for use in different sewage tanks. Moreover, the plates form a V-shaped structure, which facilitates the collection of scum. The lower part of the second telescopic frame 2012 is hinged to the foldable plate 2011. The foldable plate 2011 is composed of multiple plates, which are connected by hinges. The two ends of the second telescopic frame 2012 are also hinged to another slide rail 2034 and a support block 2013, respectively. The support block 2013 is fixedly connected to the lower part of the guide rail 202.

[0049] The bidirectional hydraulic adjustment assembly 103 includes two piston housings 1031. A handle 1032 is fixedly connected to the top of each piston housing 1031, serving as the operating point for easy lifting and transfer of the entire assembly. A guide rail 202 is fixedly connected to the bottom of the two piston housings 1031. The front and rear sides of the opposite surfaces of the two piston housings 1031 are connected by pipes. Each piston housing 1031 contains a piston rod 1033. One end of an operating rod 1034 is fixedly connected to a sealing disc 1036, which overlaps with the piston rod 1033. Both the sealing disc 1036 and the piston rod 1033 have multiple liquid holes 1035. The piston rod 1033 extends from the piston housing 1031 and is fixedly connected to a movable plate 1037. The operating rod 1034 also extends from the movable plate 1037 and is fixedly connected to an operating disc 10310. Using the operating disc 10310 as the force application point, the operating rod 1034 and the sealing disc 1036 can be rotated. After the sealing disc 1036 rotates, the liquid hole 1035 aligns with the liquid hole 1035 of the piston rod 1033, thus maintaining control of a single piston rod 1033. When the liquid hole 1035 of the sealing disc 1036 and the liquid hole 1035 of the piston rod 1033 are misaligned, the piston rod 1033 is sealed, thereby enabling the other piston rod 1033 to move synchronously using hydraulic control. The movable plate 1037 has two fixing ports 1038, and the operating disc 10310 is provided with a pin structure 1039. By inserting the pin structure 1039 into the fixing ports 1038, the position of the sealing disc 1036 can be locked to prevent the sealing disc 1036 from shifting, and one end of the pin structure 1039 extends into the fixing port 1038.

[0050] In this embodiment, by pre-expanding the first telescopic frame 1011 on one side, the side cavity 1012 extends to the edge of the sewage tank. Then, the positioning disk 1024 is rotated so that it contacts the ground downwards to maintain overall stability. Simultaneously, the second telescopic frame 2012 can be controlled by the electric hydraulic rod 204 to extend and retract the foldable plate 2011, thereby adjusting the retrieval area. Then, by pulling the side 1013, the first telescopic frame 1011 is retracted, and the first telescopic frame 1011 moves the piston housing 1031, causing the adjustable interception component 201 to move. The device can be moved, and the foldable plate 2011 can be used to pull the scum to one side. The foldable plate 2011 has a V-shaped structure, which improves the retrieval effect. This method uses the telescopic adjustability of the first telescopic frame 1011 and the second telescopic frame 2012 to meet the needs of sewage tanks of different sizes. It can also be retracted for storage, reducing the space occupied. The entire device is supported by the moving wheels 1025, which realizes the need for convenient transfer of this device. This facilitates the transfer and retrieval operations between sewage tanks, thereby greatly improving versatility and effectively reducing costs.

[0051] Example 2

[0052] Combination Figure 10 and Figure 11 It is concluded that: the vibration component 203 includes two slide rails 2034, which slide within the guide rail 202. The slide rails 2034 can slide within the guide rail 202, thus allowing the adjustable interception component 201 to smoothly achieve the vibration purpose. A spring 2035 is fixedly connected between the two guide rails 202, and one of the slide rails 2034 is fixedly connected to an electro-hydraulic rod 204. The first electro-hydraulic rod 204 is installed in the guide rail 202. A bracket 2036 is fixedly connected below one of the slide rails 2034, and a motor 2031 is fixedly mounted on the bracket 2036. The output shaft of the motor 2031 is fixedly connected to the petal cam 2032. Through the multiple petal-shaped convex surfaces of the petal cam 2032, the pulley 2033 can be reciprocated and squeezed. In conjunction with the contractile property of the spring 2035, the vibration of the adjustable interception component 201 can be achieved, which facilitates the removal of impurities on the foldable plate 2011. The pulley 2033 is attached to one side of the petal cam 2032. The pulley 2033 can reduce the frictional resistance between the pulley and the petal cam 2032 and reduce wear. The pulley 2033 is fixedly connected to another slide rail 2034.

[0053] In this embodiment: the petal cam 2032 is driven to rotate by the motor 2031. The petal cam 2032 presses the pulley 2033 to move. The pulley 2033 drives the slide rail 2034 to move and causes the spring 2035 to deform. At the same time, after the petal cam 2032 disengages from the concave surface, the spring 2035 recovers its deformation and can drive the slide rail 2034 to move. The petal cam 2032 and the spring 2035 work together to make the slide rail 2034 and the second telescopic frame 2012 vibrate. The second telescopic frame 2012 drives the foldable plate 2011 to reciprocate. The vibration of the foldable plate 2011 can shake off the attached scum and avoid scum residue. At the same time, it can be rinsed more thoroughly with a water gun.

[0054] Example 3

[0055] Combination Figure 3 and Figures 9-10 It is concluded that: the adjustment mechanism 100 includes a bidirectional hydraulic adjustment component 103, and both sides of the bidirectional hydraulic adjustment component 103 are connected to a longitudinal adjustment component 101. Two positioning components 102 are assembled below the longitudinal adjustment component 101.

[0056] The scum interception mechanism 200 includes a guide rail 202, which is located below the bidirectional hydraulic adjustment component 103. A vibration component 203 is mounted below the guide rail 202, and an adjustable interception component 201 is connected below the vibration component 203.

[0057] In this embodiment: the longitudinal adjustment component 101 drives the adjustable interception component 201 to move, thereby pulling the scum on the surface of the sewage tank to one side and smoothly pulling the scum into the collection tank. At this time, the vibration component 203 drives the adjustable interception component 201 to reciprocate and extend, so that the adjustable interception component 201 reciprocates and extends to adjust the swing angle, which facilitates the use of water guns to reduce cleaning dead angles, improves the cleaning effect, and effectively reduces maintenance costs and workload.

[0058] The working principle of this invention is as follows: When collecting scum from a sewage tank, the pin structure 1039 is moved out of the fixing port 1038, and then the operating disc 10310 is rotated, causing the operating disc 10310 to drive the operating rod 1034 to rotate. The operating rod 1034 drives the sealing disc 1036 to rotate, so that the liquid hole 1035 on the sealing disc 1036 corresponds to the liquid hole 1035 on the piston rod 1033. Then, the pin structure 1039 is inserted into the fixing port 1038 to lock the position of the operating disc 10310. Then, the first telescopic frame 1011 on one side is unfolded, so that the unfolded first telescopic frame 1011 can drive the moving wheel 1025 to move through the side cavity 1012. When the moving wheel 1025 moves to the edge 1013 of one side of the sewage tank, the positioning disc 1024 is rotated, so that the nut moves downward on the stud 1022, so that the positioning disc 1024 contacts the ground and maintains overall stability.

[0059] Then, the slide rail 2034 is moved by the electric hydraulic rod 204. The slide rail 2034 drives the second telescopic frame 2012 to unfold through the vibration component 203. The second telescopic frame 2012 drives the foldable plate 2011 to unfold, so that the foldable plate 2011 can fit the width of the sewage tank. Then, the height of the first telescopic adjustment structure 1014 and the second telescopic adjustment structure 1021 is lowered, so that the foldable plate 2011 is lowered into the sewage tank.

[0060] After the foldable plate 2011 is lowered, remove the pin structure 1039 and rotate the operating disc 10310 again, causing the operating rod 1034 to rotate the sealing disc 1036, thus misaligning the liquid hole 1035 on the sealing disc 1036 with the liquid hole 1035 on the piston rod 1033 to maintain a seal. Then, insert the pin structure 1039 into the fixing port 1038. Next, pull the side edge 1013 on one side of the unfolded first telescopic frame 1011 to retract the first telescopic frame 1011, thereby moving the piston housing 1031 and adjusting the interception assembly. Component 201 moves with piston housing 1031 and dredges scum. At the same time, the first telescopic frame 1011 drives the movable plate 1037 to move, which in turn drives the piston rod 1033 to move. Since the sealing disc 1036 is sealed with the piston rod 1033, the other piston rod 1033 can be moved by hydraulic pressure. The piston rod 1033 can then drive the other first telescopic frame 1011 to unfold through the movable plate 1037. This allows the foldable plate 2011 to pull the scum to one side and move it smoothly, so that the scum enters the collection pool next to the sewage tank.

[0061] Then, the motor 2031 is controlled to drive the petal cam 2032 to rotate. The petal cam 2032 presses the pulley 2033 to move, causing the pulley 2033 to drive the spring 2035 to deform. When the convex surface of the petal cam 2032 separates from the pulley 2033, the spring 2035 drives the slide rail 2034 to reset until the petal cam 2032 presses the pulley 2033 to move again. The petal cam 2032 and the spring 2035 work together to drive the slide rail 2034 to reciprocate. The slide rail 2034 drives the second telescopic frame 2012 to reciprocate and extend. The second telescopic frame 2012 drives the foldable plate 2011 to reciprocate and extend. The foldable plate 2011 can vibrate and shake off the surface scum. At the same time, the foldable plate 2011 is rinsed with water gun, thus cleaning the foldable plate 2011.
