Description

Technical Field

[0001] This utility model relates to the technical field of scum removal devices, specifically to a mobile liquid surface scum removal device. Background Technology

[0002] When the biological treatment system of a wastewater treatment plant operates abnormally, such as when sludge age is too long, when there are dead zones in the biological treatment tanks leading to sludge decay and floating, or when filamentous bacteria bulking occurs, scum easily forms on the surface of the biological treatment tanks. When a large amount of scum accumulates on the surface, the following adverse consequences occur: An excessively thick scum layer can create an anaerobic environment within the scum layer, causing fermentation and producing odorous gases that not only affect sensory perception but also pollute the air. Furthermore, if a large amount of scum flows into the secondary sedimentation tank, it can easily cause sludge to float in the effluent, leading to abnormal effluent parameters. To reduce the adverse effects of excessive scum on the operation of the biological treatment system, flushing is often used to remove scum in practice. However, the scum after flushing is difficult to dissolve in the water and continues to float on the surface. When the overflow holes in each biological treatment tank are below the water surface, the scum dispersed by flushing is difficult to flow into subsequent biological treatment tanks and therefore cannot be completely discharged from the biological treatment system. Over time, this will seriously affect the biological treatment system. Utility Model Content

[0022] As a further technical solution, for example, in a mobile liquid surface scum cleaning device provided in at least one embodiment of this disclosure, a float is further included, the float is disposed at the bottom of the float base, and there are floats at both ends of the float base.

[0023] As a further technical solution, for example, in at least one embodiment of the present disclosure, a mobile liquid surface scum cleaning device further includes,

[0024] The positioning seat is disposed on the outside of the scum baffle and located at the end of the scum baffle away from the scum collection box. The positioning seat is located on the outside of the scum baffle on both sides.

[0025] An adjusting screw is threadedly connected to the positioning seat, with the lower end of the adjusting screw extending below the positioning seat and the upper end extending above the positioning seat.

[0026] A connecting seat is located below the positioning seat and connected to the lower end of the adjusting screw.

It also includes...

[0029] A conveying shaft is rotatably disposed at the bottom of the scum collection box and located above the scum discharge port. The length direction of the conveying shaft is the same as the length direction of the scum collection box.

[0030] The spiral blades are arranged around the conveying shaft. After the conveying shaft drives the spiral blades to rotate, they are used to push the scum in the scum collection box to the scum discharge port.

[0031] The working principle and beneficial effects of this utility model are as follows: The float is used to float on the liquid surface and has a scum guiding surface; scum baffles are set on the float, and there are scum baffles on both sides of the scum guiding surface; the annular conveyor is set on the float and is located above the scum guiding surface; the scum collection box is set on the outer side of one end of the scum guiding surface and is located below the annular conveyor, and the scum collection box has a scum inlet that is connected to the scum guiding surface; the fixed end of the scum scraper is connected to the annular conveyor, and the scraping end of the scum scraper extends away from the annular conveyor. After the scum scraper at the end away from the scum collection box moves to below the annular conveyor, it moves towards the scum collection box to scrape the scum onto the scum guiding surface and push it towards the scum collection box, so that the scum falls into the scum collection box through the scum inlet.

[0032] The float, suspended on the liquid surface, provides support and buoyancy for the entire device, ensuring its stable floating on the surface of the biological water tank and adapting to changes in water level. The float features a scum guide surface to guide the flow of scum. Scum baffles are installed on both sides of the guide surface to prevent scum from spreading to the sides during pushing, ensuring that the scum is concentrated on the guide surface. An annular conveyor is mounted on the float and located above the guide surface, providing a track for the scum scraper, driving it to continuously circulate and collect and transport scum. A scum collection box is located on the outer side of one end of the guide surface and below the annular conveyor, with its inlet connected to the guide surface. Through its connection to the annular conveyor, the scraper scrapes scum from the water surface onto the guide surface during its movement and pushes it towards the collection box, allowing the scum to fall smoothly into the collection box through the inlet.

[0033] This device prevents scum from accumulating on the liquid surface, avoiding an excessively thick scum layer that could create an anaerobic environment, thus reducing the generation of odorous gases and lowering air pollution. It also prevents large amounts of scum from flowing into the secondary sedimentation tank, avoiding sludge floating in the effluent and ensuring normal effluent parameters, thereby reducing the adverse effects of excessive scum on the operation of the biological treatment system. Compared to traditional water flushing methods, this invention effectively collects scum into a scum collection box, preventing it from continuing to float on the liquid surface. Even when the water passages in each biological treatment tank are below the liquid surface, this device can still collect and discharge scum, preventing long-term accumulation of scum in the biological treatment system and improving its treatment efficiency and stability.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Example, refer to Figures 1-2 As one embodiment of this utility model, a mobile liquid surface scum cleaning device is proposed, including a float 1, a scum baffle 2, an annular conveyor 3, a scum collection box 4, and a scum scraper 5. The float 1 is used to float on the liquid surface and has a scum guiding surface 6. The scum baffle 2 is disposed on the float 1, with scum baffles 2 on both sides of the scum guiding surface 6. The annular conveyor 3 is disposed on the float 1 and located above the scum guiding surface 6. The scum collection box 4 is disposed on the outer side of one end of the scum guiding surface 6 and is located... Below the annular conveyor 3, the scum collection box 4 has a scum inlet 7, which is connected to the scum guide surface 6. The fixed end of the scum scraper 5 is connected to the annular conveyor 3, and the scraping end of the scum scraper 5 extends away from the annular conveyor 3. After the scum scraper 5 at the end away from the scum collection box 4 moves to the bottom of the annular conveyor 3, it moves towards the scum collection box 4 to scrape the scum onto the scum guide surface 6 and push it towards the scum collection box 4, so that the scum falls into the scum collection box 4 through the scum inlet 7.

[0044] In this embodiment, the float 1 floats on the liquid surface, providing support and buoyancy for the entire device, ensuring that the entire device can float stably on the liquid surface of the biological water tank and adapt to changes in water level. The float 1 has a scum guide surface 6. Taking the scum collection box 4 located at the left end of the scum guide surface 6 as an example, the scum guide surface 6 guides the scum to flow to the left. Scum baffles 2 are provided on both the front and rear sides of the scum guide surface 6 to prevent the scum from spreading to the front and rear sides during the leftward push, ensuring that the scum is concentrated on the scum guide surface 6. The annular conveyor 3 is located on the float 1 and above the scum guide surface 6, providing a movement track for the scum scraper 5, driving the scum scraper 5 to continuously circulate in the left and right directions, achieving continuous collection and conveying of scum. The scum collection box 4 is located outside the left end of the scum guide surface 6 and below the annular conveyor 3. The scum inlet 7 on the scum collection box 4 is connected to the scum guide surface 6. The scum scraper 5, connected to the annular conveyor 3, scrapes scum from the water surface onto the scum guide surface 6 during its left-right movement, and pushes it towards the scum collection box 4, allowing the scum to fall smoothly into the scum collection box 4 through the scum inlet 7. The scum scraper 5 is a plate-shaped structure made of silicone, which can prevent hard friction between the scum scraper 5 and the scum 1.

[0045] This device prevents scum from accumulating on the liquid surface, avoiding an excessively thick scum layer that could create an anaerobic environment, thus reducing the generation of odorous gases and lowering air pollution. It also prevents large amounts of scum from flowing into the secondary sedimentation tank, avoiding sludge floating in the effluent and ensuring normal effluent parameters, thereby reducing the adverse effects of excessive scum on the operation of the biological treatment system. Compared to traditional water flushing methods, this invention effectively collects scum into the scum collection box 4, preventing it from continuing to float on the liquid surface. Even when the water passages in each biological treatment tank are below the liquid surface, this device can still collect and discharge scum, preventing long-term accumulation of scum in the biological treatment system and improving the system's treatment efficiency and stability.

[0046] Furthermore, such as Figure 1 and Figure 2 As shown, there are multiple scum scrapers 5, all arranged along the length of the annular conveyor 3. Driven by the annular conveyor 3, the multiple scum scrapers 5 sequentially pass through different areas, ensuring that scum generated at different times and locations can be promptly scraped onto the scum guide surface 6. This allows for more comprehensive and rapid collection of scum on the liquid surface, preventing scum from remaining and accumulating in localized areas for extended periods. This further ensures the timeliness and effectiveness of scum removal from the entire biochemical water tank, enabling the device to better handle scum distributions and enhancing its overall practicality.

[0047] Furthermore, such as Figure 1As shown, the scum guide surface 6 is inclined, with the end near the scum collection box 4 tilting upwards. The annular conveyor 3 is parallel to the scum guide surface 6. Taking the scum collection box 4 located at the left end of the scum guide surface 6 as an example, the left end of the scum guide surface 6 tilts upwards. When the scum scraper 5 scrapes the scum onto the scum guide surface 6, the liquid carried in the scum can slide downwards under gravity due to the inclination angle of the inclined surface, thereby reducing the amount of liquid entering the scum collection box 4. The annular conveyor 3 is set parallel to the scum guide surface 6, ensuring that the scum scraper 5 can effectively push the scum towards the scum collection box 4 during its movement.

[0048] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes a drive shaft 8 and a driven shaft 9. The drive shaft 8 is rotatably mounted on the float 1 and located at one end near the scum collection box 4. The length direction of the drive shaft 8 is perpendicular to the length direction of the scum baffle 2. The driven shaft 9 is rotatably mounted at the other end of the float 1. The length direction of the driven shaft 9 is perpendicular to the length direction of the scum baffle 2. There are annular conveyor components 3 on both sides of the scum guide surface 6. Each annular conveyor component 3 is simultaneously connected to both the drive shaft 8 and the driven shaft 9. The scum scraper 5 is connected between the annular conveyor components 3 on both sides.

[0049] Taking the scum collection box 4 located at the left end of the scum guide surface 6 as an example, the drive shaft 8 is rotatably set at the left end of the float 1, and the driven shaft 9 is rotatably set at the right end of the float 1. The axes of the drive shaft 8 and the driven shaft 9 are both set in the front-back direction. The two annular conveyor components 3 are simultaneously connected to the drive shaft 8 and the driven shaft 9 for transmission. When the drive shaft 8 rotates, it drives the driven shaft 9 to rotate synchronously through the annular conveyor component 3, thereby enabling the annular conveyor component 3 to circulate and provide a stable motion track for the scum scraper 5, realizing the function of the scum scraper 5 continuously circulating on the liquid surface to scrape and push scum. The drive shaft 8, the driven shaft 9, and the annular conveyor component 3 work together to build a stable and reliable power transmission system, ensuring that the annular conveyor component 3 and the scum scraper 5 can operate stably for a long time, providing a basic guarantee for the continuous operation of the entire scum cleaning device, ensuring that the scum collection operation can be carried out without interruption, adapting to the working needs of long-term and large-volume scum cleaning, and effectively maintaining the scum accumulation on the surface of the biochemical water tank at a low level.

[0050] Furthermore, such as Figure 1 and Figure 2As shown, it also includes a first rotary drive mechanism 24 and a first reducer 25. The first rotary drive mechanism 24 is mounted on the scum collection box 4; the first reducer 25 is mounted on the scum collection box 4, with one end of the first reducer 25 connected to the output shaft of the first rotary drive mechanism 24 and the other end of the first reducer 25 connected to the drive shaft 8. The first rotary drive mechanism 24 and the first reducer 25 are located above the rear end of the scum collection box 4. The first rotary drive mechanism 24 drives the drive shaft 8 to rotate through the first reducer 25, and the rotation speed of the drive shaft 8 can be adjusted according to the actual situation to better meet the scum removal requirements.

[0051] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the annular conveyor 3 is a chain, and also includes a drive sprocket 10 and a driven sprocket 11. The drive sprocket 10 is mounted on the drive shaft 8, with drive sprockets 10 coaxially mounted at both ends of the drive shaft 8. The driven sprockets 11 are mounted on the driven shaft 9, with driven sprockets 11 coaxially mounted at both ends of the driven shaft 9. The annular conveyor 3, drive sprockets 10, and driven sprockets 11 form a chain drive. There are two drive sprockets 10 on the drive shaft 8 and two driven sprockets 11 on the driven shaft 9. The front end of the annular conveyor 3 forms a chain drive with the front drive sprockets 10 and driven sprockets 11, and the rear end of the annular conveyor 3 forms a chain drive with the rear drive sprockets 10 and driven sprockets 11. The chain drive has the characteristics of accurate transmission ratio, high transmission efficiency, and stable operation in harsh environments. The power of the drive shaft 8 can be accurately transmitted to the driven shaft 9 through the sprockets and chain, driving the annular conveyor 3 to rotate cyclically, thereby driving the scum scraper 5 to move along a predetermined trajectory. It can ensure the regularity and stability of the movement of the scum scraper 5, ensuring that the scraping and pushing action of the scum scraper 5 on the scum can be carried out accurately each time. It can reduce abnormal movement of the scum scraper 5 caused by unstable transmission, improve the reliability of the entire device for scum cleaning, and at the same time, the chain drive is relatively durable, which can reduce the maintenance cost of the device during long-term operation.

[0052] Furthermore, such as Figure 1 and Figure 3As shown, it also includes a fastening clamp 28, a fastening bolt 29, and a fastening nut 30. The fastening clamp 28 is set on the annular conveyor 3, and there are fastening clamps 28 on both sides of the scum scraper 5. The end of the scum scraper 5 is clamped between the fastening clamps 28 on both sides. The fastening bolt 29 is inserted into the scum scraper 5 and the fastening clamps 28 on both sides of the scum scraper 5. The fastening nut 30 is threaded into the fastening bolt 29. The scum scraper 5 and the fastening clamps 28 on both sides of the scum scraper 5 are clamped between the nut of the fastening bolt 29 and the fastening nut 30. When the scum scraper 5 needs to be replaced, simply loosen the fastening bolt 29 and the fastening nut 30 for replacement. The structure is simple, the connection is firm and reliable, and the disassembly and assembly are convenient and quick, saving time and effort. The fastening clamp 28 is fixed to the annular conveyor 3 by locking bolts and can also be disassembled and replaced.

[0053] Furthermore, such as Figure 1 and Figure 3 As shown, it also includes a support member 12, a clamping member 13, and a locking member 14. The support member 12 is disposed on the float 1 and located at the end of the float 1 away from the scum collection box 4. There are support members 12 at both ends of the driven shaft 9. The support member 12 has a height adjustment groove 15. The end of the driven shaft 9 is inserted into the height adjustment groove 15, and the width of the height adjustment groove 15 is greater than the diameter of the end of the driven shaft 9. The clamping member 13 is fitted around the end of the driven shaft 9 and is located outside the support member 12. The clamping member 13 and the driven shaft 9 form a sliding fit. The locking member 14 is threaded to the end of the driven shaft 9 and is located outside the clamping member 13. After the locking member 14 is rotated, the clamping member 13 is clamped between the locking member 14 and the support member 12, which is used to lock the driven shaft 9 and the support member 12.

[0054] Two support members 12 are provided at the right end of the float 1, one at the front and one at the back. Each support member 12 has a height adjustment groove 15. The front and rear ends of the driven shaft 9 are respectively inserted into the corresponding height adjustment grooves 15. The clamping member 13 is clamped between the locking member 14 and the support member 12, thus locking the driven shaft 9 to the support member 12 and stopping the driven shaft 9 at the desired height. When the height of the driven shaft 9 needs to be adjusted, rotate the locking member 14 to separate the clamping member 13 from the support member 12, and then adjust the up and down position of the driven shaft 9. After adjustment, rotate the locking member 14 again to clamp the clamping member 13 between the locking member 14 and the support member 12. The structure is simple, the adjustment is convenient and quick, and it saves time and effort.

[0055] Furthermore, such as Figure 1 As shown, it also includes a float 16, which is disposed at the bottom of the float base 1, and there are floats 16 at both ends of the float base 1. The floats 16 at both ends can provide buoyancy, so that the float base 1 can float stably on the liquid surface.

[0056] Furthermore, such as Figure 1As shown, it also includes a positioning seat 17, an adjusting screw 18, and a connecting seat 19. The positioning seat 17 is located on the outside of the scum baffle 2 and at the end of the scum baffle 2 away from the scum collection box 4. There are positioning seats 17 on the outside of the scum baffle 2 on both sides. The adjusting screw 18 is threadedly connected to the positioning seat 17. The lower end of the adjusting screw 18 extends below the positioning seat 17, and the upper end of the adjusting screw 18 extends above the positioning seat 17. The connecting seat 19 is located below the positioning seat 17 and is connected to the lower end of the adjusting screw 18. The float 16 away from the scum collection box 4 is located below the connecting seat 19. After the adjusting screw 18 is rotated, it is used to drive the connecting seat 19 and the float 16 to rise and fall.

[0057] There are positioning seats 17 on the outer right side of both front and rear scum baffles 2. Each positioning seat 17 is threaded with an adjusting screw 18. Rotating the adjusting screw 18 will drive the connecting seat 19 and the float 16 below to move up and down, thereby adjusting the height of the float 16, thus changing the buoyancy distribution and floating attitude of the entire device. The height of the float 16 can be flexibly adjusted according to the actual liquid surface conditions, scum distribution and other factors, thereby adjusting the draft of the device, so that the device can better adapt to different working conditions.

[0058] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes an adjustment disc 20, which is connected to the upper end of the adjustment screw 18. The adjustment disc 20 can increase the force-bearing area of ​​the adjustment screw 18 during operation, making it easier for the operator to apply rotational force, making the operation of rotating the adjustment screw 18 more labor-saving and convenient, and facilitating precise adjustment of the height of the float 16.

[0059] Furthermore, such as Figure 1 and Figure 2 As shown, the width of the lower end of the scum collection box 4 gradually decreases. At the bottom of one end of the scum collection box 4, there is a scum discharge port 21. It also includes a conveying shaft 22 and a spiral blade 23. The conveying shaft 22 is rotatably disposed at the bottom of the scum collection box 4 and is located above the scum discharge port 21. The length direction of the conveying shaft 22 is the same as the length direction of the scum collection box 4. The spiral blade 23 is disposed around the conveying shaft 22. After the conveying shaft 22 drives the spiral blade 23 to rotate, it is used to push the scum in the scum collection box 4 to the scum discharge port 21.

[0060] The width of the scum collection box 4 gradually decreases from left to right at its lower end. The conveying shaft 22 is positioned along the front-to-back direction along its length. The scum discharge port 21 is located at the rear end of the scum collection box 4 and is connected to the conveying pipe. When scum falls into the scum collection box 4, the conveying shaft 22 rotates, driving the spiral blades 23 to rotate. Utilizing the spiral propulsion of the spiral blades 23, the scum in the scum collection box 4 is pushed towards the scum discharge port 21. With the assistance of the gradually narrowing structure at the lower end of the scum collection box 4, the scum can be pushed more smoothly to the scum discharge port 21 and discharged from the scum collection box 4 through the conveying pipe. This allows for the automatic discharge of scum from the scum collection box 4, eliminating the need for frequent manual cleaning. This improves the automation level of the entire scum cleaning device and ensures that the scum can be discharged in an orderly and smooth manner, preventing excessive accumulation of scum in the scum collection box 4 that could affect subsequent collection work. This maintains the device's continuous and efficient scum cleaning capacity.

[0061] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes a second rotary drive mechanism 26 and a second reducer 27. The second rotary drive mechanism 26 is mounted on the scum collection box 4; the second reducer 27 is mounted on the scum collection box 4, with one end of the second reducer 27 connected to the output shaft of the second rotary drive mechanism 26 and the other end connected to the conveying shaft 22. The second rotary drive mechanism 26 and the second reducer 27 are located in front of the scum collection box 4. The second rotary drive mechanism 26 drives the conveying shaft 22 to rotate through the second reducer 27, and the rotation speed of the conveying shaft 22 can be adjusted according to actual conditions to better meet the scum discharge requirements.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
