Description

Technical Field

[0001] The invention relates to the technical field of aquaculture tail water treatment, in particular to industrial aquaculture tail water circulation treatment equipment. Background Art

[0002] Industrial aquaculture effluent is wastewater generated during industrial aquaculture. The environmental protection treatment of industrial aquaculture effluent aims to reduce environmental pollution, improve water resources and the reuse rate of organic matter in wastewater. The treatment process usually includes physical treatment, chemical treatment, biological treatment and other treatment procedures. Among them, physical treatment mainly separates solid matter in wastewater by filtration, chemical treatment mainly removes soluble pollutants, heavy metals and other substances in wastewater through chemical reactions, and biological treatment mainly removes organic matter, ammonia nitrogen and other pollutants in wastewater through the metabolism of microorganisms, so that the wastewater meets the discharge standards or reuse requirements.

[0003] At present, physical treatment of aquaculture wastewater usually separates suspended matter and sediments accordingly. For example, one or more stages of screens are set up to intercept floating objects, and one or more stages of sedimentation tanks are set up to separate sediments. The whole treatment process is relatively complicated and requires regular salvage of intercepted objects, cleaning of screens, and regular discharge of sediments. The overall workload is large, and the efficiency and stability of continuous operation are poor, which makes it difficult to fully meet the needs of large-scale farms for efficient treatment of aquaculture wastewater. Summary of the invention

[0004] The industrial aquaculture tail water circulation treatment equipment provided by the present invention aims to solve the problems in the related technology of large workload in the aquaculture wastewater treatment process, poor efficiency and stability in continuous operation, and difficulty in fully meeting the needs of large-scale farms for efficient treatment of aquaculture wastewater.

[0005] The present invention provides an industrial aquaculture tail water circulation treatment device. The industrial aquaculture tail water circulation treatment device includes a separation bin provided with a rotating frame. An arc-shaped separation area, a pressure filtration area, and a blanking area are demarcated in the separation bin. Wastewater passes through the separation area. A number of separation units are provided on the rotating frame. The separation units sequentially pass through the separation area, the pressure filtration area, and the blanking area as the rotating frame rotates. And before any one separation unit leaves the separation area, at least one other separation unit enters the separation area. The separation unit includes a separation component and a cleaning component. The separation component includes a filter plate fixedly installed on the rotating frame and a sliding frame provided with a number of plugging heads and slidably connected to the filter plate. The cleaning component and the sliding frame are respectively located on both sides of the filter plate. The cleaning component includes a moving seat provided with a rolling head and a scraping head. The moving seat reciprocates to synchronously control the rolling head and the scraping head to move from one side of the filter plate to the other side. During the process when the rolling head is in the working state, the scraping head is in the non-working state. When the scraping head is in the non-working state, it abuts against the rolling head. When the separation unit passes through the pressure filtration area, the sliding frame first abuts against the filter plate, so that the plugging heads plug the filter holes on the filter plate to form a non-porous plate. Then the moving seat moves to make the rolling head roll the filter material on the non-porous plate. When the separation unit passes through the blanking area, when the moving seat returns to its original position, the scraping head scrapes the filter material on the non-porous plate. Among them, the plugging heads and the filter holes on the filter plate are both conical structures, and the plugging heads are adapted to the filter holes. A collection bin provided with a feed inlet, and the collection bin is arranged on the rotating frame 1, and the feed inlet is located in the blanking area.

[0006] In a possible implementation manner, an adaptive control component is provided on the moving seat. The adaptive control component automatically controls the working state of the scraping head during the process of the moving seat reciprocating along the axial direction of the separation bin. The adaptive control component includes a forward ratchet wheel, a reverse ratchet wheel, and a control gear that are coaxially and fixedly connected. All three are fixedly connected to the scraping head. Forward ratchet teeth and reverse ratchet teeth are arranged on the control seat. The forward ratchet teeth are engaged with the forward ratchet wheel, and the reverse ratchet teeth are engaged with the reverse ratchet wheel. The forward ratchet teeth and the reverse ratchet teeth are staggered from each other and are not in the engaged state at the same time. An adaptive rod one that meshes with the control gear is slidably arranged on the moving seat along the axial direction of the separation bin. During the process of the moving seat reciprocating, the adaptive rod one will reciprocate under the abutting limit of the rotating frame.

[0007] In a possible implementation manner, the control seat includes a sliding member. The sliding member is slidably connected to the moving seat along the radial direction of the separation bin. The forward ratchet teeth and the reverse ratchet teeth are both arranged on the sliding member. A control rod is threadedly connected to the sliding member. An adaptive rod two is slidably connected to the moving seat along the axial direction of the separation bin. The adaptive rod two meshes with the control rod. During the process of the moving seat reciprocating, the adaptive rod two will reciprocate under the abutting limit of the rotating frame.

[0008] In a possible implementation manner, a control frame is slidably connected along the axial direction of the separation chamber on the rotating frame. A connecting rod is hinged between the control frame and the sliding frame, and a control screw rod is threadedly connected to the control frame. The control screw rod is rotatably connected to the rotating frame. A gear-rack assembly is arranged between the separation chamber and the control screw rod, and the gear-rack assembly automatically controls the control screw rod to rotate intermittently with a gap during the rotation of the rotating frame.

[0009] In a possible implementation manner, the rotating frame includes a central frame fixedly connected with a mounting frame. The central frame is rotatably connected in the separation chamber and always abuts against the collection chamber during rotation. The filter plate is mounted on the mounting frame. A baffle is fixedly connected to the central frame, and the baffles are respectively located on both sides of the filter plate and are used to block the scraping head and the rolling head.

[0010] In a possible implementation manner, one end of the collection chamber extends outside the separation chamber, and a discharge port is arranged on the part of the collection chamber located outside the separation chamber. A conveyor belt is arranged in the collection chamber and extends from the discharge port to the outside of the collection chamber.

[0011] In a possible implementation manner, the separation chamber includes a chamber body with an annular structure. A liquid inlet and a liquid outlet are formed in the chamber body. The area between the liquid outlet and the liquid inlet is the separation area. The position of the liquid outlet is lower than the horizontal midline of the chamber body. During the rotation of the rotating frame, the adaptive control component on the moving seat does not contact the wastewater in the separation area.

[0012] One or more of the above technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0013] 1. The separation unit in the present invention will sequentially pass through the separation area, the pressure filtration area, and the blanking area as the rotating frame rotates, realizing the coherent treatment of separating floating substances and some precipitates from the wastewater and collecting them centrally, and continuously and cyclically performing the foregoing coherent treatment, effectively improving the efficiency of wastewater solid-liquid separation treatment. During the continuous working process, the filter plate always maintains a highly efficient and stable filtering state, further improving the efficiency of wastewater solid-liquid separation treatment, and effectively improving the stability and reliability of the wastewater solid-liquid separation treatment process.

[0014] 2. The adaptive control component in the present invention automatically controls the working state of the scraping head during the reciprocating movement of the moving seat and makes the scraping head in a stable working state, so that the scraping head and the rolling head cooperate stably and reliably to complete the pressure filtration and blanking work of the filter material, and no additional drive is required, which is beneficial to improving the stability and reliability of the wastewater treatment process.

[0015] 3. In the present invention, the moving seat drives the scraping head and the rolling head to reciprocate synchronously, successively completing the pressure filtration and discharging of the separated matter. During the whole process, the filter plate is in a pore-free state under the plugging of the plugging head, effectively preventing the filtered matter from entering the filter pores and affecting the filtration effect, thereby ensuring the stability and reliability of the continuous filtration state of the filter plate, and further improving the stability and reliability of the continuous separation and treatment of wastewater.

[0028] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0029] Please refer to Figure 1 and Figure 2 , an industrial aquaculture tail water circulation treatment device, including a separation bin 2 provided with a rotary rack 1. An arc-shaped separation area, a pressure filtration area and a blanking area are divided in the separation bin 2; As Figure 2As shown, the separation chamber 2 includes a chamber body 21 with an annular structure. A liquid inlet 22 is provided on the right side of the chamber body 21, and a liquid outlet 23 is provided on the left side. The area between the liquid outlet 23 and the liquid inlet 22 is the separation area. The pressure filtration area and the blanking area are arranged counterclockwise in sequence starting from the liquid inlet 22. A number of separation units 3 are provided on the rotating frame 1. The separation units 3 rotate counterclockwise with the rotating frame 1 and sequentially pass through the separation area, the pressure filtration area, and the blanking area. At least two separation units 3 are located in the separation area at the same time. As the separation units 3 rotate with the rotating frame 1 and pass through the separation area, the solid substances in the waste liquid are separated out (the rotating frame 1 is driven to rotate by an existing drive source). Then, it enters the pressure filtration area to remove the moisture in the solid substances and then enters the blanking area, so that the solid substances are separated from the separation units 3. Then, the separation units 3 enter the separation area again and repeat the above steps, thereby continuously and cyclically separating the solid substances in the wastewater. And during the continuous separation of the solid substances in the wastewater, the separated solid substances are timely separated from the separation units 3, which is convenient for continuously and efficiently performing solid-liquid separation treatment on the wastewater. During the continuous solid-liquid separation of the wastewater, the wastewater passes through the separation area in a continuously flowing state. And before the separation units 3 leave the separation area, at least one other separation unit 3 enters the separation area to ensure that the solid substances in the wastewater are fully separated out. During the continuous and efficient solid-liquid separation treatment of the wastewater, the separation quality is fully improved, and the separation units 3 do not need to be cleaned regularly during the whole process, nor do they need to salvage floating substances. Among them, the wastewater is pumped into the liquid inlet 22 by an existing device and can flow out of the liquid outlet 23 automatically. The liquid outlet 23 can face the subsequent treatment pool, so that the liquid directly flows into the treatment pool.

[0030] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 and Figure 10, the separation unit 3 includes a separation component 31 and a cleaning component 32. The separation component 31 includes a filter plate 311 fixedly installed on the rotating frame 1 and a sliding frame 313 provided with a number of plugging heads 312 and slidably connected to the filter plate 311. The cleaning component 32 and the sliding frame 313 are respectively located on both sides of the filter plate 311, and the cleaning component 32 includes a moving seat 323 provided with a rolling head 321 and a scraping head 322. The moving seat 323 is reciprocally connected to the rotating frame 1 in the front-back direction, and the rolling head 321 and the scraping head 322 move synchronously with the moving seat 323. During the process of wastewater solid-liquid separation treatment, when the separation unit 3 passes through the separation area, the filter plate 311 is in a filtering state. The moving seat 323, the rolling head 321, and the scraping head 322 are all located on the rear side of the filter plate 311, and the rolling head 321 is located in front of the scraping head 322. When the separation unit 3 passes through the pressure filtration area, the sliding frame 313 first abuts against the filter plate 311, so that the plugging heads 312 plug the filter holes on the filter plate 311 to form a poreless plate. Then the moving seat 323 moves forward to make the rolling head 321 roll the filter material on the poreless plate to remove the moisture in the filter material. During this process, the scraping head 322 does not contact the filter plate 311 and is in a non-filtering working state. The poreless plate can effectively prevent the filter material from entering the filter holes on the filter plate 311 during the pressure filtration process and affecting the filtering effect of the filter plate 311. After that, when the separation unit 3 passes through the blanking area, the moving seat 323 resets backward. During this process, the scraping head 322 abuts against the poreless plate and separates the filter material from the poreless plate as the moving seat 323 moves. Then, before the separation unit 3 passes through the blanking area and enters the separation area again, the sliding frame 313 separates from the filter plate 311, so that the filter plate 311 returns to the filtering working state and enters the separation area in a stable filtering state for filtering and separation work. Among them, a collection bin 5 is provided in the rotating frame 1, and a feed inlet 4 is opened on the collection bin 5. The feed inlet 4 is located below the blanking area. During the process that the separation unit 3 passes through the blanking area, the separated material enters the collection bin 5 through the feed inlet 4. Both the plugging heads 312 and the filter holes on the filter plate 311 are conical structures, and the plugging heads 312 are adapted to the filter holes, which is convenient for the smooth formation of the poreless plate.

[0031] Refer to Figure 2 , Figure 4 , Figure 6 and Figure 7, an adaptive control component 33 is provided on the moving seat 323. The adaptive control component 33 automatically controls the working state of the scraping head 322 during the reciprocating movement of the moving seat 323 back and forth. The adaptive control component 33 includes a forward ratchet wheel 331, a reverse ratchet wheel 332, and a control gear 333 that are coaxially and fixedly connected together. The three are distributed from top to bottom in sequence and fixedly connected to the scraping head 322. The scraping head 322 is rotatably connected to the moving seat 323. A control seat 336 is provided on the moving seat 323. A forward ratchet tooth 334 and a reverse ratchet tooth 335 are provided on the control seat 336. The forward ratchet tooth 334 meshes with the forward ratchet wheel 331, and the reverse ratchet tooth 335 meshes with the reverse ratchet wheel 332. The forward ratchet tooth 334 and the reverse ratchet tooth 335 are staggered from each other and they are not in the meshing state at the same time. During the forward movement of the moving seat 323, the rolling head 321 performs the rolling work. The forward ratchet tooth 334 meshes with the forward ratchet wheel 331. At this time, the forward ratchet wheel 331 and the scraping head 322 can only rotate counterclockwise and cannot rotate clockwise, which is convenient for keeping the scraping head 322 in a stable non-working state. And during the process that the moving seat 323 is about to stop moving, the control seat 336 first controls the forward ratchet tooth 334 and the reverse ratchet tooth 335 to move radially towards the center of the bin body 21 along the bin body 21, so that the forward ratchet tooth 334 is separated from the forward ratchet wheel 331, and the reverse ratchet tooth 335 meshes with the reverse ratchet wheel 332. Then the scraping head 322 is rotated to make the scraping head 322 in the working state; then the moving seat 323 stops moving forward and starts to move backward for reset. During this process, the scraping head 322 clings to the surface of the perforation-free plate, so that the separated matter is separated from the perforation-free plate, and the scraping head 322 can only rotate clockwise at this time. Therefore, it can be stably in the scraping working state, improving the stability and reliability of its working process. When the moving seat 323 is about to be reset, the control seat 336 controls the forward ratchet tooth 334 and the reverse ratchet tooth 335 to move synchronously radially away from the center of the bin body 21 along the bin body 21, so that the forward ratchet tooth 334 meshes with the forward ratchet wheel 331, and the reverse ratchet tooth 335 is separated from the reverse ratchet wheel 332. Then the scraping head 322 is rotated to make the scraping head 322 in the non-working state, which is convenient for the moving seat 323 to move forward again to make the rolling head 321 perform the rolling work. Among them, an adaptive rod one 337 that meshes with the control gear 333 is slidably arranged back and forth on the moving seat 323. During the reciprocating movement of the moving seat 323 back and forth, the front end or the rear end of the adaptive rod one 337 will abut against the corresponding area on the rotating frame 1. Then as the moving seat 323 continues to move, the adaptive rod one 337 will slide relatively under the block of the rotating frame 1 and the sliding direction is opposite to the moving direction of the moving seat 323. Furthermore, the scraping head 322 is driven to rotate through the control gear 333. When the scraping head 322 is in the non-working state, it abuts against the rolling head 321 (such as Figure 6As shown in the figure, at this time, the scraping head 322 scrapes the surface of the rolling head 321 during the rolling process of the rolling head 321, which can effectively prevent the separation material from adhering to the rolling head 321 and affecting its work. Among them, an intermediate gear is meshed between the control gear 333 and the first adaptive rod 337. As Figure 6 shown, the first adaptive rod 337 is directly meshed with the intermediate gear rotatably installed on the moving seat 323, and the intermediate gear is meshed with the control gear 333; when the first adaptive rod 337 moves forward with the moving seat 323, under the limit of the rotating frame 1, the first adaptive rod 337 will relatively slide and rotate the intermediate gear under the block of the rotating frame 1, and the intermediate gear drives the control gear 333 to rotate so that the scraping head 322 rotates backward into the working state. On the contrary, when the moving seat 323 moves backward, the scraping head 322 rotates forward into the non-working state.

[0032] Refer to Figure 4 、 Figure 6 and Figure 7 , the control seat 336 includes a sliding member 3361. The sliding member 3361 is slidably connected to the moving seat 323 along the radial direction of the bin body 21. The forward ratchet 334 and the reverse ratchet 335 are both arranged on the sliding member 3361. A control rod 3362 extending along the radial direction of the bin body 21 is threadedly connected to the sliding member 3361. A second adaptive rod 3363 is slidably connected to the moving seat 323 in the front-back direction. A tooth section is arranged on the second adaptive rod 3363, and the tooth section is meshed with the concentric gear arranged on the control rod 3362; during the process of the moving seat 323 reciprocating back and forth, the front end or the rear end of the second adaptive rod 3363 will contact the corresponding area on the rotating frame 1, and then as the moving seat 323 continues to move, the second adaptive rod 3363 will relatively slide under the block of the rotating frame 1 and the sliding direction is opposite to the moving direction of the moving seat 323. The relative sliding of the second adaptive rod 3363 will cause the control rod 3362 to rotate; the length of the second adaptive rod 3363 is greater than the length of the first adaptive rod 337 (as Figure 6As shown, the adaptive rod two 3363 will contact the rotary frame 1 prior to the adaptive rod one 337. And to smoothly control the reciprocating rotation of the control rod 3362 and the reciprocating rotation of the scraping head 322, during the sliding process of the adaptive rod two 3363, it will initially slide a compensation distance, which is the same as the moving distance of the adaptive rod one 337 for controlling the reciprocating rotation of the scraping head 322. And during this process, the tooth segment on the adaptive rod two 3363 does not engage with the concentric gear on the control rod 3362. After that, as the adaptive rod two 3363 continues to move, the tooth segment on the adaptive rod two 3363 engages with the concentric gear on the control rod 3362 to drive the control rod 3362 to rotate, and controls the slider 3361 to slide in the radial direction of the bin body 21, switching the meshing state between the forward ratchet 334 and the reverse ratchet 335. After the switching is completed, the adaptive rod two 3363 and the adaptive rod one 337 move synchronously until the scraping head 322 switches to the working state. After that, during the reverse movement of the moving seat 323, the working processes of the adaptive rod two 3363 and the adaptive rod one 337 are the same as the foregoing, thereby enabling the switching of the entire working state of the scraping head 322 to be automatically completed during the movement of the moving seat 323 without additional driving and allowing for long-term stable operation.

[0033] Refer to Figure 1 and Figure 2 , the height position of the liquid outlet 23 is lower than the horizontal midline of the bin body 21, and during the rotation of the rotary frame 1, the adaptive control assembly 33 on the moving seat 323 does not contact the waste water in the separation area, improving the stability and reliability of its long-term operation.

[0034] Refer to Figure 2 , Figure 3 , Figure 5 , Figure 8 , Figure 10 and Figure 11, a control frame 314 is slidably connected to the front and rear of the rotating frame 1. A connecting rod 315 is hinged between the control frame 314 and the sliding frame 313. By sliding the control frame 314 back and forth, the sliding frame 313 can be controlled to fit and separate from the filter plate 311 through the connecting rod 315. The control frame 314 is in a U-shaped structure. The number of connecting rods 315 is several and they are evenly divided into two groups. The two groups of connecting rods 315 are symmetrically distributed up and down and are respectively located on both sides of the sliding frame 313 along the radial direction of the bin body 21. By sliding the control frame 314 back and forth, the sliding of the sliding frame 313 can be stably controlled through the connecting rod 315, thereby realizing the fitting and separation of the sliding frame 313 and the filter plate 311. A control screw 316 is threadedly connected to the control frame 314. By rotating the control screw 316 reciprocally, the control frame 314 can be controlled to move back and forth reciprocally. The control screw 316 is rotatably connected to the rotating frame 1, and a gear-rack assembly 317 is arranged between the separation bin 2 and the control screw 316. The gear-rack assembly 317 includes two arc-shaped racks 3171, several first gear sets 3172 and several second gear sets 3173. A first gear set 3172 and a second gear set 3173 form a control unit, and the control units correspond to the control screws 316 one by one. The arc-shaped racks 3171 are fixedly installed on the bin body 21 and are staggered front and back. In the control unit, the first gear set 3172 is coaxially and fixedly connected to the corresponding control screw 316, and the second gear set 3173 is rotatably connected to the central frame 102. Both the first gear set 3172 and the second gear set 3173 are composed of two coaxially and fixedly connected gears. The two coaxially and fixedly connected gears are in a front-back distribution state, and the first gear set 3172 and the second gear set 3173 are staggered front and back; the front gear in the first gear set 3172 meshes with the front arc-shaped rack 3171, and the rear gear meshes with the front gear in the second gear set 3173. The rear gear in the second gear set 3173 meshes with the rear arc-shaped rack 3171 (as Figure 11 shown); during the rotation of the central frame 102, when the gear-rack assembly 317 passes through the front arc-shaped rack 3171, the front gear in the first gear set 3172 meshes with the front arc-shaped rack 3171 and directly drives the control screw 316 to rotate. When the gear-rack assembly 317 passes through the rear arc-shaped rack 3171, the rear gear in the second gear set 3173 meshes with the rear arc-shaped rack 3171 and controls the control screw 316 to rotate through the first gear set 3172. The rotation directions of the control screw 316 in the two times are opposite. Therefore, during the rotation of the rotating frame 1, the control screw 316 can be automatically driven to rotate intermittently and reciprocally, and then the control frame 314 can be automatically controlled to move back and forth reciprocally.

[0035] Refer to Figure 2 , Figure 3 , Figure 5 , Figure 8 , Figure 10 and Figure 11, the rotating frame 1 includes a central frame 102 fixedly connected with a mounting frame 101. The central frame 102 is rotatably connected in the separation chamber 2 and always abuts against the collection chamber 5 during rotation. The filter plate 311 is installed on the mounting frame 101. A baffle 103 is fixedly connected to the central frame 102. The baffle 103 is located on the front and rear sides of the filter plate 311 respectively and is used to block the scraping head 322 and the rolling head 321. During the process that the separation unit 3 passes through the separation area, as the rotating frame 1 rotates, the baffle 103 is located on the side of the scraping head 322 and the rolling head 321 close to the rotation direction of the rotating frame 1, which can effectively prevent solids in the sewage from adhering to the scraping head 322 and the rolling head 321 to a certain extent. And before the separation unit 3 passes through the feeding area and has not entered the separation area yet, in the case that a small amount of separated matter remains on the front or rear side of the filter plate 311, the baffle 103 can effectively prevent the part of the separated matter remaining on the filter plate 311 from falling into the sewage and flowing out through the liquid outlet 23 along with the sewage, which is beneficial to improving the quality of solid-liquid separation of wastewater. Among them, the central frame 102 can be rotated by meshing with its outer side and being rotatably connected to a transmission member connected to an external driving source. The transmission member includes a transmission gear and a transmission shaft (such as Figure 11 shown).
