Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, and in particular relates to a sewage treatment scum collection device. Background Technology

[0002] Sludge in wastewater treatment refers to the aggregate of suspended matter that forms on the surface of wastewater during the wastewater treatment process due to the action of physical, chemical, or biological treatment methods. These substances are usually lighter than water, so they float on the water surface to form a layer of sludge. In the field of wastewater treatment, the effective collection of sludge is crucial to ensuring the efficiency of the treatment process and the final water quality.

[0003] In the prior art, Chinese Patent Publication No. CN219009955U discloses a scum collection device for a sewage treatment pond, comprising: a sewage pond, with guide blocks fixedly installed on the inner wall of the sewage pond; a collection structure installed on the top surface of the sewage pond, the collection structure including an outer frame, the outer frame being movably installed inside the top surface of the sewage pond, guide grooves being provided on the left and right side walls of the outer frame, a filter plate being movably installed on the inner side of the outer frame via bearings, worm gears being fixedly connected to the front and rear ends of the filter plate, and worm gears being movably installed on the front and rear walls of the outer frame via bearings. This utility model collection device, by setting a flip-up filter plate, can maintain a vertical downward state when the outer frame moves downward, allowing scum to pass between two adjacent sets of filter plates, and maintain a horizontal state when moving upward, so that the scum can be collected on the top surface of the filter plate, making it easy to dredge and collect the scum. The structure is simple and more practical.

[0004] In existing wastewater treatment equipment, scum collection and wastewater mixing are two separate operational steps, completed by different equipment. Usually, the scum collection operation can only be carried out after the wastewater and suspending agent have been mixed and all the scum has floated to the surface. The whole process takes a long time, has low efficiency, and makes it difficult to ensure the continuity of the entire wastewater treatment process. Utility Model Content

[0005] The purpose of this utility model is to provide a scum collection device for sewage treatment, in order to solve the technical problem mentioned in the background art that in the existing sewage treatment devices, scum collection and sewage mixing are two independent operation steps. The scum collection operation can only be carried out after the sewage and suspending agent have been mixed and all the scum has floated up. The whole working time is long, the work efficiency is low, and it is difficult to ensure the continuity of the entire sewage treatment process.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A sewage treatment scum collection device includes an installation frame, a treatment tank is provided on the installation frame, a support frame is installed at the upper end of the treatment tank, a scum collection mechanism and a mixing mechanism are provided on the support frame, the scum collection mechanism includes a collection component for collecting sewage scum, a conveying component for conveying the collected scum, and a collection box for collecting the scum, and a controller is installed on one side of the installation frame;

[0007] A fixed frame is provided on one side of the mounting frame. Several treatment devices for treating sewage are installed inside the fixed frame. One end of the fixed frame is provided with a conveying device for conveying sewage to the treatment devices. The output end of the treatment device is connected to a conveying pipe, which is connected to the treatment tank.

[0008] The mixing mechanism includes a motor, a rotating shaft, and stirring blades. The motor is fixedly installed in the middle of the support frame, the output end of the motor is fixedly connected to the rotating shaft, and the stirring blades are fixedly installed on the rotating shaft.

[0009] The converging assembly includes a converging plate, one end of which is fixedly connected to a connecting sleeve, which is movably sleeved on the rotating shaft.

[0010] The converging plate has a recess in the middle and a converging opening is provided in the recess. A converging box is fixedly installed on one side of the middle of the converging plate, and the opening of the converging box is connected to the converging opening.

[0011] The converging assembly also includes a hydraulic cylinder, which is fixedly mounted on a support frame, and a lifting plate is fixedly connected to the output end of the hydraulic cylinder.

[0012] A guide rod is fixedly connected to the lower surface of one side of the support frame, and the end of the lifting plate away from the hydraulic cylinder is slidably sleeved on the guide rod.

[0013] The connecting sleeve is rotatably connected to the lower surface of the lifting plate, and a groove is provided at the bottom of the connecting sleeve.

[0014] A connecting ring is provided below the connecting sleeve. The connecting ring is fixedly sleeved on the rotating shaft. A protrusion is provided on the upper surface of the connecting ring. The groove and the protrusion are inserted into each other.

[0015] The conveying assembly includes a conveying pump, which is fixedly installed at one end of the support frame. The two ends of the conveying pump are respectively connected to a discharge pipe and a feed pipe. One end of the discharge pipe is fixedly connected to a collection box, and one end of the feed pipe is fixedly connected to a collection cover.

[0016] A sealing cylinder is fixedly connected to the bottom of the collection hood, and a sealing ring is fixedly connected to the bottom of the sealing cylinder. The sealing ring abuts against the inner wall of the bottom of the collection box.

[0017] The wastewater treatment scum collection device of this utility model has the following advantages:

[0018] 1. This wastewater treatment scum collection device uses a collection component to collect scum into a collection box for easy transport. A hydraulic cylinder is activated to move a lifting plate downwards, which in turn moves a connecting sleeve and a collection plate downwards simultaneously, causing a protrusion to engage with a groove. After engagement, the connecting ring rotates with the shaft, causing the connecting sleeve and the collection plate to rotate synchronously. This causes the collection plate to move in a circular motion along the scum on the water surface. During rotation, the scum flows towards the central depression and eventually enters the collection box through the collection port, achieving scum aggregation. The hydraulic cylinder parameters are set according to the motor speed. When the collection plate rotates to directly below the sealing ring, the hydraulic cylinder is activated, moving the collection plate and collection box upwards. The protrusion disengages from the groove, and the connecting sleeve no longer rotates synchronously with the shaft, thus allowing scum collection to occur simultaneously with the mixing operation.

[0019] 2. This wastewater treatment scum collection device involves an upward-facing collection box that abuts against a sealing ring to seal the bottom of a sealing cylinder. A pump is then activated to transport the scum from the sealing cylinder to the collection box, cleaning the collection box and freeing up space for continued scum collection. After a certain period of cleaning, once the rotating shaft has rotated a specified number of times, a hydraulic cylinder is activated to move the collection plate downwards, re-engaging the connecting sleeve with the connecting ring to continue collecting the scum.

[0020] 3. This wastewater treatment scum collection device, by combining a collection component with a mixing mechanism, can simultaneously collect scum into a collection box during the mixing process. Through the cooperation of the collection component and the conveying component, the scum in the collection box can be collected and cleaned without affecting the mixing process, thereby improving the smoothness of scum collection and the overall efficiency of wastewater treatment, and ensuring the normal operation of wastewater treatment.

[0036] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a sewage treatment scum collection device.

[0037] like Figures 1-8 As shown, a sewage treatment scum collection device of the present invention includes a mounting frame 1, a treatment tank 9 is provided on the mounting frame 1, a support frame 10 is installed on the upper end of the treatment tank 9, a scum collection mechanism and a mixing mechanism 5 are provided on the support frame 10, the scum collection mechanism includes a collection component 2 for collecting sewage scum, a conveying component 3 for conveying the collected scum and a collection box 4 for collecting scum, and a controller 8 is installed on one side of the mounting frame 1.

[0038] A fixed frame 11 is installed on one side of the mounting frame 1. Several treatment devices 6 for treating sewage are installed inside the fixed frame 11. A conveying device 12 for conveying sewage to the treatment device 6 is provided at one end of the fixed frame 11. The output end of the treatment device 6 is connected to a conveying pipe 7, which is connected to the treatment tank 9.

[0039] Specifically, wastewater is introduced into the treatment device 6 inside the fixed frame 11 via the conveying device 12. Here, the wastewater undergoes preliminary treatment, such as sedimentation and chemical treatment, to reduce large particulate pollutants in the wastewater. After pretreatment, the wastewater then enters the treatment tank 9 through the conveying pipe 7. A suspending agent is introduced into the treatment tank 9, and the wastewater and suspending agent are mixed by the mixing mechanism 5, causing the pollutants to float to the surface. During the mixing process, the collecting plate 21 in the collecting component 2 rotates synchronously with the stirring blades 53, guiding and causing the scum to concentrate in the middle of the collecting plate 21. Then, the collected scum is transported to the collection box 4 on the side by the conveying component 3, realizing the collection of wastewater scum.

[0040] The mixing mechanism 5 includes a motor 51, a rotating shaft 52, and a stirring blade 53. The motor 51 is fixedly installed in the middle of the support frame 10, and the output end of the motor 51 is fixedly connected to the rotating shaft 52. The stirring blade 53 is fixedly installed on the rotating shaft 52.

[0041] In this application, the mixing mechanism 5 is used to mix the sewage and the added suspending agent in the treatment tank 9. During operation, the motor 51 drives the rotating shaft 52 and the stirring blades 53 to rotate. The stirring blades 53 are triangular and arranged circumferentially on the rotating shaft 52. Each stirring blade 53 is provided with several through holes, which can generate a strong turbulent effect between the sewage and the suspending agent during rotation, thereby accelerating the dispersion of the suspending agent and fully contacting the particulate matter in the sewage, promoting flocculation and accelerating the formation of scum.

[0042] The converging assembly 2 includes a converging plate 21, with a connecting sleeve 27 fixedly connected to one end of the converging plate 21. The connecting sleeve 27 is movably sleeved on the rotating shaft 52. The converging plate 21 has a recess in the middle, and a converging port 23 is provided in the recess. A converging box 22 is fixedly installed on one side of the middle of the converging plate 21. The opening of the converging box 22 communicates with the converging port 23. The converging assembly 2 also includes a hydraulic cylinder 24, which is fixedly installed on the support frame 10. A lifting plate 25 is fixedly connected to the output end of the hydraulic cylinder 24. A guide rod 26 is fixedly connected to the lower surface of one side of the support frame 10. The end of the lifting plate 25 away from the hydraulic cylinder 24 is slidably sleeved on the guide rod 26. The connecting sleeve 27 is rotatably connected to the lower surface of the lifting plate 25. A groove 28 is provided at the bottom of the connecting sleeve 27. A connecting ring 29 is provided below the connecting sleeve 27. The connecting ring 29 is fixedly sleeved on the rotating shaft 52. A protrusion 210 is provided on the upper surface of the connecting ring 29. The groove 28 and the protrusion 210 are correspondingly inserted.

[0043] The collecting component 2 is used to collect scum into the collecting box 22 for easy transport. Specifically, the hydraulic cylinder 24 is activated to move the lifting plate 25 downward. The lifting plate 25 moves the connecting sleeve 27 and the collecting plate 21 downward synchronously, so that the protrusion 210 engages with the groove 28. After engagement, the connecting ring 29 rotates with the rotating shaft 52, causing the connecting sleeve 27 and the collecting plate 21 to rotate synchronously. This causes the collecting plate 21 to move in a circle along the scum on the water surface. During the rotation, the scum flows towards the central depression and finally enters the collecting box 22 through the collecting port 23, thus achieving the collection of scum. The parameters of the hydraulic cylinder 24 are set according to the speed of the motor 51. When the collecting plate 21 rotates to directly below the sealing ring 36, the hydraulic cylinder 24 is activated, causing the collecting plate 21 and the collecting box 22 to move upward. The protrusion 210 disengages from the groove 28, and the connecting sleeve 27 no longer rotates synchronously with the rotating shaft 52, so that the scum collection operation is carried out simultaneously with the mixing operation.

[0044] The conveying assembly 3 includes a conveying pump 31, which is fixedly installed at one end of the support frame 10. The two ends of the conveying pump 31 are respectively connected to a discharge pipe 32 and a feed pipe 33. One end of the discharge pipe 32 is fixedly connected to the collection box 4, and one end of the feed pipe 33 is fixedly connected to a collection cover 34. A sealing cylinder 35 is fixedly connected to the bottom of the collection cover 34, and a sealing ring 36 is fixedly connected to the bottom of the sealing cylinder 35. The sealing ring 36 abuts against the inner wall of the bottom of the collecting box 22.

[0045] Specifically, the collecting box 22 abuts against the sealing ring 36, sealing the bottom of the sealing cylinder 35. The scum inside the sealing cylinder 35 is transported to the collecting box 4 by starting the conveying pump 31, thus cleaning the collecting box 22 and freeing up space for the continued collection of scum. After cleaning for a certain period of time, when the rotating shaft 52 rotates a specified number of times, the hydraulic cylinder 24 is started to drive the collecting plate 21 to move down, so that the connecting sleeve 27 re-engages with the connecting ring 29, and the collection of scum continues.

[0046] Working principle of a sewage treatment scum collection device:

[0047] Wastewater is introduced into the treatment device 6 within the fixed frame 11 via the conveying device 12. Here, the wastewater undergoes preliminary treatment, such as sedimentation and chemical treatment, to reduce large particulate pollutants. After pretreatment, the wastewater then enters the treatment tank 9 through the conveying pipe 7. A suspending agent is introduced into the treatment tank 9, and the motor 51 is started to drive the rotating shaft 52 and the stirring blades 53 to rotate, allowing the suspending agent to fully contact the particulate matter in the wastewater, promoting flocculation and accelerating the formation of scum. The collecting plate 21 rotates synchronously with the rotating shaft 52, making a circular motion along the scum on the water surface. During the rotation, the scum flows towards the central depression and finally enters the collecting box 22 through the collecting port 23, realizing the aggregation of scum. When the collecting plate 21 rotates to directly below the sealing ring 36, the hydraulic cylinder 24 is activated, driving the collecting plate 21 and the collecting box 22 to move upward. The protrusion 210 disengages from the groove 28, and the connecting sleeve 27 no longer rotates synchronously with the rotating shaft 52. The collecting box 22 abuts against the sealing ring 36, sealing the bottom of the sealing cylinder 35. The conveying pump 31 is activated to transport the scum in the sealing cylinder 35 to the collecting box 4, cleaning the collecting box 22 and freeing up space to continue the scum collection operation. After cleaning for a certain period of time, when the rotating shaft 52 rotates a specified number of times, the hydraulic cylinder 24 is activated again to drive the collecting plate 21 downward, so that the connecting sleeve 27 re-engages with the connecting ring 29, continuing the collection of scum.

[0048] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
