Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and mainly mentions a multimodal circulating integrated water pollution treatment device. Background Technology

[0002] Integrated water pollution treatment devices typically integrate physical, biological, and chemical treatment units to achieve efficient and compact wastewater treatment. According to research, their specific processes include physical treatment units (bars, screens, etc., for intercepting suspended solids), biofilm treatment units (degrading organic matter through anaerobic or aerobic reactions), and chemical treatment units (coagulation sedimentation, disinfection, etc., for in-depth cleaning).

[0003] The principle of biofilm wastewater treatment is that microorganisms attach and grow on the surface of the packing layer to form a biofilm. The biofilm removes organic pollutants from the wastewater through adsorption, oxidation, and decomposition. However, during the operation of the biofilm, impurities in the wastewater (suspended solids, aged biofilm, etc.) accumulate on the biofilm in the packing layer. Existing packing layers usually adopt a rigid fixed structure (such as a steel frame) and cannot be moved during use. This causes the accumulated impurities or aged biofilm to clog the pores of the packing, increase water flow resistance, and lead to short-circuiting or dead zones. At the same time, the accumulated impurities also hinder the wastewater and affect the contact between the wastewater and the biofilm, thereby reducing the wastewater treatment efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings described in the background art, the present invention provides a multimodal circulating integrated water pollution treatment device.

[0005] The technical implementation scheme of the present invention is as follows: a multimodal circulating integrated water pollution treatment device, comprising a treatment tank, a fixed frame fixedly connected to the treatment tank, a first frame and a second frame arranged on the fixed frame, and a plurality of pairs of mounting plates fixedly connected to both the first frame and the second frame, the mounting plates on the first frame and the mounting plates on the second frame being staggered, each pair of mounting plates being fixedly connected to a packing component, a driving mechanism provided on the fixed frame for driving the first frame and the second frame to move relative to each other, and a regulating mechanism provided on the fixed frame for controlling the distance between each pair of mounting plates, thereby changing the state of all the packing components.

[0006] In one preferred embodiment, the driving mechanism includes: a drive motor fixedly connected to the fixed frame; and two winches, both mounted on the fixed frame and used to drive the first frame and the second frame to move relative to each other, wherein the input shafts of the two winches are connected to the output shaft of the drive motor via a bevel gear set.

[0007] In one preferred embodiment, the control mechanism includes: a mounting sleeve fixedly connected to the fixed frame; a rotating sleeve rotatably connected to the mounting sleeve; a sliding sleeve threadedly connected to the rotating sleeve, the sliding sleeve being slidably connected to the mounting sleeve; a rotating rod rotatably connected to the sliding sleeve; and an intercepting block fixedly connected to the lower side of the rotating rod, the intercepting block being used to limit the movement of the corresponding mounting plate on the first frame and the corresponding mounting plate on the second frame.

[0008] In one preferred embodiment, the packing element is made of an elastic material and has a spiral structure.

[0009] In one preferred embodiment, two corresponding packing elements on two adjacent mounting plates are in a wound state, forming a spiral packing module.

[0010] In one preferred embodiment, both the first frame and the second frame consist of upper and lower parts, and connecting ropes are provided between the upper and lower parts of the first frame and between the upper and lower parts of the second frame to facilitate changes in the distance between each pair of mounting plates.

[0011] In one preferred embodiment, all the spiral packing modules on three adjacent mounting plates are staggered.

[0012] In one preferred embodiment, a first limiting plate and a second limiting plate are fixedly connected to the fixing frame. Both the first frame and the second frame are fixedly connected to a protruding post. The protruding post on the first frame is slidably connected to the first limiting plate, and the protruding post on the second frame is slidably connected to the second limiting plate.

[0013] In one preferred embodiment, the first limiting plate and the second limiting plate are located on adjacent and different sides of the fixing frame.

[0014] In one preferred embodiment, both the first limiting plate and the second limiting plate are provided with wave grooves, and the two protruding pillars slide within the wave grooves of the first limiting plate and the second limiting plate, respectively.

[0015] Compared with the prior art, the present invention has the following advantages: The present invention scrapes off the impurities attached to the surfaces of two corresponding packing elements on two adjacent mounting plates by cyclically moving up and down relative to each other, thereby ensuring the cleanliness of the packing elements and extending their service life.

[0016] This invention uses a spiral structure for the packing material to guide wastewater, enhance fluid turbulence, effectively cut bubbles, improve oxygen transfer rate and mass transfer efficiency, and is more adaptable to high-concentration wastewater while reducing energy consumption.

[0017] This invention sets two corresponding filler pieces on two adjacent mounting plates in a wound state, so that when they are stretched, they are close to each other, which facilitates the scraping and cleaning of impurities on the filler pieces.

[0018] The present invention can adjust the position of the intercepting block by rotating the rotating sleeve according to the concentration of wastewater, thereby changing the state of the packing components so that the state of the packing components corresponds to the concentration of wastewater, thus ensuring the efficiency of wastewater treatment and increasing the applicability of the device.

[0019] The present invention guides the first frame and the second frame respectively through the first limiting plate and the second limiting plate, thereby causing all the filling parts to vibrate, which facilitates the removal of impurities accumulated on them. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," and "right," etc., appearing or about to appear in this text, are based solely on the accompanying drawings and are not intended to specifically limit the invention. Example 1

[0035] This embodiment discloses a multimodal circulating integrated water pollution treatment device, which has the function of vibrating the packing components, thereby causing the impurities accumulated on them to fall off.

[0036] like Figures 1-10 As shown, the system includes a treatment tank 10 for holding wastewater. A fixing frame 20 is bolted to the treatment tank 10. A first frame 30 and a second frame 40 are mounted on the fixing frame 20. Several pairs of mounting plates 50 are fixed to both the first frame 30 and the second frame 40. In this application, the first frame 30 has three pairs of mounting plates 50, and the second frame 40 has four pairs of mounting plates 50. Each pair of mounting plates 50 is arranged vertically, and the mounting plates 50 on the first frame 30 and the second frame 40 are staggered (e.g., ...). Figure 10 Each pair of mounting plates 50 is fixedly connected to a packing element 60. The packing element 60 provides a place for anaerobic microorganisms (such as hydrolytic acidifying bacteria and methanogenic bacteria) to attach and grow. The fixed frame 20 is equipped with a driving mechanism, which is used to drive the first frame 30 and the second frame 40 to move relative to each other. By moving the first frame 30 up and down, all the packing elements 60 on the first frame 30 are moved (the same applies to the second frame 40). The fixed frame 20 is equipped with two sets of control mechanisms, which are located on the left and right sides of the fixed frame 20, respectively. The control mechanisms are used to control the distance between each pair of mounting plates 50, thereby changing the state of all the packing elements 60.

[0037] like Figures 6-9As shown, the packing element 60 is made of elastic material and has a spiral structure. The spiral structure enhances fluid turbulence, effectively cuts bubbles, improves oxygen transfer rate and mass transfer efficiency, and is more adaptable to high-concentration wastewater, reducing energy consumption. The corresponding packing elements 60 on two adjacent mounting plates 50 are in a winding state, forming a spiral packing module, so that when they are stretched, they can be close to each other. All the spiral packing modules on three adjacent mounting plates 50 are staggered, improving the uniformity of contact between the packing element 60 and the wastewater. In this embodiment, the packing element 60 is in a contracted state. The winding state of two adjacent packing elements 60 allows them to be close to each other. The relative up-and-down movement of the two adjacent packing elements 60 scrapes off the impurities attached to their surfaces, ensuring the cleanliness of the packing element 60 and extending its service life.

[0038] like Figures 1-3 As shown, the drive mechanism includes: a drive motor 21, fixedly connected to the fixed frame 20; and two winches 22, both mounted on the fixed frame 20, which are used to drive the first frame 30 and the second frame 40 to move relative to each other. The winches 22 are provided with two take-up rollers, each of which is fixedly connected with a connecting rope. The connecting ropes of the two take-up rollers on the same winch 22 are fixedly connected to the first frame 30 and the second frame 40 respectively. The two winches 22 are used to drive the first frame 30 and the second frame 40 to move relative to each other.

[0039] like Figures 1-3 and Figures 11-13As shown, the control mechanism includes: a mounting sleeve 31, fixedly connected to the fixed frame 20; a rotating sleeve 32, rotatably connected to the mounting sleeve 31, with a handwheel on its upper side for easy operation; a sliding sleeve 33, threadedly connected to the rotating sleeve 32, the rotating sleeve 32 driving the sliding sleeve 33 to move up and down, the sliding sleeve 33 being slidably connected to the mounting sleeve 31; a rotating rod 34, rotatably connected to the sliding sleeve 33, the rotating rod 34 also having a handwheel on its upper side for easy operation; and an intercepting block 35, fixedly connected to the lower side of the rotating rod 34, the intercepting block 35 limiting the corresponding mounting plate 50 on the first frame 30 and the corresponding mounting plate 50 on the second frame 40, through... The mounting plates 50 at the bottom of the first frame 30 and the second frame 40 are contacted to restrict their range of movement, thereby limiting the first frame 30 and the second frame 40 and preventing them from sliding further downward. The first frame 30 and the second frame 40 are both composed of upper and lower parts, and connecting ropes are provided between the upper and lower parts of the first frame 30 and the upper and lower parts of the second frame 40. Each pair of mounting plates 50 on the first frame 30 is located at the upper and lower parts of the first frame 30 respectively (the same applies to the second frame 40), so that the distance between each pair of mounting plates 50 can be changed. Initially, the connecting ropes are in a slack state, and one of the mounting plates 50 on the lower side of the first frame 30 is in contact with the intercepting block 35, and one of the mounting plates 50 on the lower side of the second frame 40 is in contact with the intercepting block 35.

[0040] Working principle:

[0041] When wastewater treatment is required, first place all the packing components 60 into the designated positions in the treatment tank 10 (e.g., Figure 2 As shown in the diagram, a certain amount of wastewater (enough to cover all the packing elements 60) is then injected into the treatment tank 10. At this time, the packing elements 60 provide attachment sites for anaerobic microorganisms in the wastewater. During the growth of microorganisms on the packing elements 60, a biofilm is gradually formed. The biofilm comes into contact with the wastewater and adsorbs and degrades pollutants such as organic matter, nitrogen, and phosphorus in the wastewater. Purification is achieved through microbial metabolic activities. As the treatment time increases, impurities in the wastewater will accumulate on the packing elements 60, thus hindering the contact between the biofilm and the wastewater. Therefore, the packing elements 60 need to be cleaned regularly. The specific cleaning steps are as follows:

[0042] The operator rotates the rotating sleeve 32, which rotates relative to the mounting sleeve 31. Simultaneously, the rotating sleeve 32 drives the sliding sleeve 33 to move downwards via the thread. The sliding sleeve 33 drives the intercepting block 35 to move downwards via the rotating rod 34. During this process, the two mounting plates 50 in contact with the intercepting block 35 move downwards under the action of gravity, and the intercepting block 35 always remains in contact with the corresponding mounting plate 50. At the same time, the two mounting plates 50 drive the lower parts of the first frame 30 and the lower parts of the second frame 40 to move downwards, respectively. The connecting rope in the middle of the first frame 30 and the second frame 40 is gradually straightened. During this process, the lower part of the first frame 30 drives all the mounting plates 50 on it to move downwards (the same applies to the lower part of the second frame 40). The distance between each pair of mounting plates 50 gradually increases, and the packing element 60 between each pair of mounting plates 50 is gradually stretched until the rotating sleeve 32 rotates to its limit position, at which point the packing element 60 is stretched to its limit. At this point, the middle parts of the two packing elements 60 on the same spiral packing module cross each other and approach each other.

[0043] After the rotating sleeve 32 is rotated to its limit position, the operator stops rotating the rotating sleeve 32 and rotates the rotating rod 34. The rotating rod 34 drives the intercepting block 35 to rotate, so that the intercepting block 35 loses contact with the two corresponding mounting plates 50, thereby causing the lower part of the first frame 30 and the lower part of the second frame 40 to lose their limit.

[0044] After the interceptor block 35 loses contact with the corresponding two mounting plates 50, the operator stops rotating the rotating rod 34 and then turns on the drive motor 21. The output shaft of the drive motor 21 drives the two winches 22 to start working (rotating in the forward direction) through the bevel gear set. During this process, the two winches 22 drive the first frame 30 to move upward and drive the second frame 40 to move downward. During this process, the first frame 30 drives the packing component 60 on it to move upward, and the second frame 40 drives the packing component 60 on it to move downward. The two packing components 60 on the same spiral packing module begin to move up and down relative to each other. The position of the two packing components 60 approaching each other changes constantly, and the two begin to rub against each other, thereby scraping off the accumulated impurities on the two packing components 60, improving the cleanliness of the packing components 60, making it easier for the biofilm on them to continue to contact the wastewater, and improving the wastewater treatment efficiency.

[0045] After the output shaft of the drive motor 21 rotates forward for a preset time, the output shaft of the drive motor 21 begins to rotate in the opposite direction for the same duration, causing the first frame 30 to move downward and driving the second frame 40 to move upward, thereby continuing to clean the impurities accumulated on the packing components 60. This cycle is repeated three to five times. The output shaft of the drive motor 21 drives the two winches 22 to reset and restore the first frame 30 and the second frame 40 to their initial height. At the same time, the drive motor 21 is turned off. At this time, all the packing components 60 are in a stretched state.

[0046] After turning off the drive motor 21, the operator rotates the rotating rod 34 in the opposite direction, causing the intercepting block 35 to rotate in the opposite direction and re-engage with the corresponding two mounting plates 50. This again limits the intercepting block 35 to the first frame 30 and the second frame 40. Then, the operator rotates the rotating sleeve 32 in the opposite direction. The rotating sleeve 32 drives the intercepting block 35 to move upward through the sliding sleeve 33 and the rotating rod 34. The intercepting block 35 drives the lower part of the first frame 30 and the lower part of the second frame 40 to move upward through the corresponding two mounting plates 50. This causes the lower part of the first frame 30 to drive all the mounting plates 50 on it to move upward (the same applies to the lower part of the second frame 40). The connecting ropes of the first frame 30 and the second frame 40 gradually loosen, and all the filling parts 60 gradually retract until the rotating sleeve 32 is reset. Then, the operator stops rotating the rotating sleeve 32, thus completing the cleaning of all the filling parts 60.

[0047] When treating wastewater, if the wastewater concentration is too high, the packing material will become clogged, resulting in poor water flow. Conversely, if the wastewater concentration is too low, the water flow will be too strong, leading to insufficient microbial attachment and affecting the treatment effect. Therefore, staff can adjust the state of the packing material 60 according to the wastewater concentration, as follows:

[0048] If the concentration of wastewater gradually decreases, the staff can rotate the sleeve 32, so that the rotating sleeve 32 drives the intercepting block 35 to move downward through the sliding sleeve 33 and the rotating rod 34. Repeat the above operation to gradually stretch all the packing parts 60, so that all the packing parts 60 gradually deform to a tight state, reduce the impact force of wastewater, and prevent excessive shedding of biofilm due to water flow impact, thus promoting full contact between biofilm and wastewater.

[0049] If the concentration of wastewater gradually increases, the staff can rotate the sleeve 32 to move the intercepting block 35 upward, thereby gradually compressing all the packing components 60, increasing the distance between two adjacent packing components 60, reducing the possibility of blockage, increasing the flow of wastewater, and ensuring that the biofilm can better contact the wastewater. Example 2

[0050] This embodiment discloses a multimodal circulating integrated water pollution treatment device, which also has a way to further change the state of the packing element 60, thereby improving the cleaning effect of the packing element 60.

[0051] like Figure 1 , Figure 2 and Figure 4As shown, two first limiting plates 51 and two second limiting plates 52 are fixedly connected to the fixed frame 20. The two first limiting plates 51 are symmetrically distributed and located on the front and rear sides of the fixed frame 20, respectively. The two second limiting plates 52 are also symmetrically distributed and located on the left and right sides of the fixed frame 20, respectively. Two protruding posts 53 are fixedly connected to both the first frame 30 and the second frame 40. The protruding posts 53 on the first frame 30 are slidably connected to the adjacent first limiting plate 51, and the protruding posts 53 on the second frame 40 are slidably connected to the adjacent second limiting plate 52. The first limiting plates 51 and the second limiting plates 52 are respectively... The protruding posts 53 on the first frame 30 and the second frame 40 are located on adjacent and different sides of the fixed frame 20, and the directions of movement of the protruding posts 53 on the first frame 30 and the second frame 40 are intersected; both the first limiting plate 51 and the second limiting plate 52 are provided with wave grooves. The wave groove on the first limiting plate 51 is bent in the left and right direction, so that the first frame 30 vibrates in the left and right direction; the wave groove on the second limiting plate 52 is bent in the front and back direction, so that the second frame 40 vibrates in the front and back direction, and the two protruding posts 53 slide in the wave grooves of the corresponding first limiting plate 51 and the second limiting plate 52 respectively.

[0052] Working principle:

[0053] During the relative movement of the first frame 30 and the second frame 40, taking the upward movement of the first frame 30 as an example, the first frame 30 drives the protruding post 53 on it to move upward. The protruding post 53 slides along the wave groove of the adjacent first limiting plate 51. The wave groove of the first limiting plate 51 guides the protruding post 53, causing the protruding post 53 to drive the first frame 30 to vibrate in the left and right directions. The first frame 30 drives all the packing parts 60 on it to vibrate synchronously. The vibration of the packing parts 60 causes the impurities accumulated on the packing parts 60 to fall quickly, ensuring the cleanliness of the packing parts 60.

[0054] As the second frame 40 moves downward, it drives the protruding post 53 on it to move upward. The protruding post 53 slides along the wave groove on the adjacent second limiting plate 52, thereby causing the second frame 40 to drive all the packing parts 60 on it to vibrate in the front and back direction, so that the impurities accumulated on it can fall off.

[0055] During the relative movement of two adjacent packing components 60, the two packing components 60 scrape each other in the vertical direction. During this process, the two adjacent packing components 60 vibrate synchronously, causing the two adjacent packing components 60 to scrape each other in the horizontal direction, thereby improving the cleaning effect of the packing components 60.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention.
