Description

Technical Field

[0001] This invention relates to the field of water pollution environmental protection treatment technology, specifically to a filtration and recycling device for wastewater from dried scallop processing. Background Technology

[0002] Direct discharge of industrial wastewater not only causes serious water pollution and disrupts the aquatic ecological balance, but also wastes recyclable resources in the wastewater. Water pollution protection equipment is designed to prevent environmental pollution by treating wastewater through multi-stage filtration, maintaining ecological balance, and protecting human survival and health.

[0003] Patent publication number CN209957543U relates to a filter box with a hollow rectangular structure and an opening at the top. A collection box is connected to one side wall of the filter box, and a drive motor is screwed to the connection between the collection box and the filter box. The output shaft of the drive motor is connected to a horizontally positioned rotating rod, the end of which penetrates the filter box and extends to the other side of the filter box, where a vertically positioned main gear disk is connected. This device has a novel structure and can effectively filter wastewater, promptly clean solid impurities on the filter screen, and improve filtration efficiency. Furthermore, the device can mix and stir the filtered wastewater and purifying agent, improving wastewater treatment and recovery efficiency.

[0004] While it can clean solid impurities on the filter screen in a timely manner and mix and stir the filtered wastewater and purifying agent to improve wastewater treatment and recycling efficiency, the device is prone to incomplete collection of waste residue during wastewater treatment, reducing the overall cleaning effect of the equipment. At the same time, when adding agents, it is easy to cause wastewater to contaminate the agents, reducing the treatment effect of the agents. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wastewater filtration and recycling device for dried scallop shreds processing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater filtration and recovery device for dried scallop processing, comprising a wastewater filtration tower, an inlet fixedly connected to the wastewater filtration tower, an outlet fixedly connected to the wastewater filtration tower, a first filter plate fixedly connected to the wastewater filtration tower, a second filter plate fixedly connected to the wastewater filtration tower, a motor fixedly connected to the wastewater filtration tower, the output end of the motor fixedly penetrating the outer wall of the wastewater filtration tower, a first reciprocating screw fixedly connected to the output end of the motor, a storage groove formed inside the first reciprocating screw, a sliding groove formed inside the wastewater filtration tower, and the wastewater filtration and recovery device for dried scallop processing further comprising an impurity recovery mechanism installed on the first reciprocating screw and a chemical spraying mechanism installed inside the wastewater filtration tower; The impurity recovery mechanism includes a capture shell mounted on the reciprocating lead screw, a rotating rod mounted inside the capture shell, a gear mounted on the rotating rod, a waste residue rotating plate mounted on the rotating rod, a rotating ring mounted on the rotating rod, and a toothed ring mounted in the chute of the wastewater filter tower. The capture shell is in contact with the outer wall of the filter plate, the rotating ring is in contact with the chute of the wastewater filter tower, the outer wall of the waste residue rotating plate is in contact with the filter plate, the gear meshes with the toothed ring, and the circumferential surface of the rotating ring is in contact with the toothed ring.

[0007] When treating wastewater, the starting motor drives the reciprocating screw to rotate, which in turn drives the capture shell to rotate. The capture shell then drives the waste residue rotating plate to rotate, thereby rotating and turning the waste residue into the interior of the capture shell. This process can clean the blockages on the surface of the filter plate in real time, maintain the permeability of the filter holes, ensure the continuous and stable operation of the device, extend its service life, and reduce the overall cost of filter media replacement and manual maintenance.

[0008] The agent spraying mechanism includes a medicine box installed in the wastewater filtration tower, a medicine inlet pipe installed in the wastewater filtration tower, a reciprocating screw two installed in the wastewater filtration tower, a piston plate installed in the reciprocating screw one, a baffle plate installed on the piston plate, and a spray box installed on the reciprocating screw one.

[0009] While performing rotary filtration, the first reciprocating screw drives the piston plate to rotate. The rotation of the piston plate causes the second reciprocating screw to move back and forth, thereby compressing the agent and spraying it through the one-way valve. This prevents the agent from being continuously over-added and combining with the wastewater to form flocs, thus improving the filtration and retention effect. It also achieves automated and precise agent dosing and reduces manual intervention.

[0010] The reciprocating screw one has a medicine inlet, the medicine box is in contact with the circumferential surface of the reciprocating screw one, the circumferential surface of the reciprocating screw two is slidably embedded with the piston plate, the outer wall of the baffle is in contact with the reciprocating screw one, and a one-way valve is installed in the spray box.

[0011] The wastewater filtration and recycling device also includes a capture mechanism installed on the capture shell, which is used to knock off the impurities on the filter plate. The capture mechanism includes a positioning block installed on the outer wall of the capture shell, a sliding rod installed in the positioning block, a pulley installed in the sliding rod, a striking block installed on the sliding rod, and a trapezoidal block installed in the wastewater filter tower.

[0012] When capturing waste residue, the capture shell rotates, causing the positioning block to rotate. The positioning block then moves the striking block to strike the filter plate. The vibration and impact force can break the adhesion between the filter cake and the filter plate, causing the filter cake layer to loosen and fall off, and quickly clearing the blocked filter holes.

[0013] The capture mechanism also includes an anti-clogging mechanism installed on the reciprocating lead screw, used to capture impurities and flocculent matter in the wastewater; The anti-clogging mechanism includes a connecting block mounted on the reciprocating lead screw, a fixing frame mounted on the connecting block, and an activated carbon plate mounted inside the fixing frame.

[0014] While the purifying agent is being sprayed, the reciprocating screw rotates, causing the activated carbon plate to rotate and capture waste residue and flocculent matter in the wastewater. This achieves efficient capture throughout the entire flow channel, significantly reducing the risk of clogging of subsequent filter plates and the pollutant load of biochemical treatment, and avoiding localized blockages.

[0015] The trapezoidal block has an inclined surface on its outer wall, and the trapezoidal block contacts the inclined surface of the pulley.

[0016] The wastewater filtration and recycling device also includes an auxiliary mechanism installed inside the fixed frame to increase the waste residue capture area of ​​the fixed frame. The auxiliary mechanism includes a rotating rod installed in the fixed frame, a capture plate installed on the rotating rod, a telescopic hinge rod installed on the rotating rod, a connecting rod installed on the telescopic hinge rod, a roller installed on the connecting rod, and a cam installed on the filter plate.

[0017] While the activated carbon plate captures flocculent matter, the fixed frame rotates, causing the rotating rod to rotate. The rotating rod then rotates the capture plate, which in turn rotates the telescopic hinge rod. The telescopic hinge rod then rotates the connecting rod, which in turn rotates the roller. This efficient capture effectively removes suspended solids and some organic matter from wastewater, resulting in a significant reduction in the concentration of suspended solids in the treated effluent and reducing the need for fresh water.

[0018] The auxiliary mechanism also includes a heating mechanism installed on the reciprocating lead screw, used to control the wastewater temperature; The heating mechanism includes a limiting rod installed inside the wastewater filter tower, a ring installed on the reciprocating lead screw, and a heater installed on the ring.

[0019] During wastewater treatment, the reciprocating screw drives the ring to move back and forth, which in turn drives the heater to move back and forth to heat the wastewater, thereby improving wastewater treatment efficiency, reducing wastewater viscosity and flow resistance, making flocculants easier to settle or be captured, and increasing filtration throughput and overall treatment efficiency.

[0020] A torsion spring is provided between the rotating rod and the fixed frame, the capturing plate is in contact with the fixed frame, the roller is in contact with the cam, and the circumferential surface of the limiting rod is slidably embedded in the ring.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when treating wastewater, the starting motor drives the reciprocating screw one to rotate, which in turn drives the capture shell to rotate. The capture shell then drives the waste residue rotating plate to rotate, thereby rotating and turning the waste residue into the interior of the capture shell. This process can clean the blockage on the surface of the filter plate in real time, maintain the permeability of the filter pores, ensure continuous and stable operation of the device, extend its service life, and reduce the overall cost of filter media replacement and manual maintenance. After the wastewater undergoes multi-stage purification by the equipment, harmful substances are significantly reduced, the river water no longer turns black and smelly, the surrounding water environment is improved, water pollution is reduced, water quality safety and aquatic ecology are protected, the living environment is improved, water resources are saved, and human health is protected. While performing rotary filtration, the reciprocating screw one drives the piston plate to rotate. The rotation of the piston plate is reciprocated by the reciprocating screw two, thereby compressing the agent and spraying it through a one-way valve. This prevents the continuous excessive addition of the agent from causing it to combine with the wastewater to form flocs, improving the filtration and interception effect, and realizing the automation and precision of agent dosing, reducing manual intervention.

[0022] 2. In this invention, when capturing waste residue, the rotating capture shell drives the rotating positioning block, which in turn drives the moving striking block to strike the filter plate. The vibration and impact force can break the adhesion between the filter cake and the filter plate, causing the filter cake layer to loosen and fall off, quickly clearing the blocked filter holes. While the purifying agent is being sprayed, the rotating reciprocating screw drives the rotating activated carbon plate to capture waste residue and flocculent matter in the wastewater, achieving efficient capture throughout the entire flow channel. This significantly reduces the risk of clogging of subsequent filter plates and the pollutant load of biochemical treatment, avoiding localized blockage.

[0023] 3. In this invention, while the activated carbon plate captures flocculent matter, the fixed frame rotates, causing the rotating rod to rotate. The rotating rod then rotates the capture plate, which in turn rotates the telescopic hinge rod. The telescopic hinge rod then rotates the connecting rod, which in turn rotates the roller. This efficient capture effectively removes suspended solids and some organic matter from the wastewater, significantly reducing the concentration of suspended solids in the treated effluent and minimizing the need for fresh water. Simultaneously, the reciprocating screw drives the ring to move back and forth, which in turn drives the heater to move back and forth to heat the wastewater. This improves wastewater treatment efficiency, reduces the viscosity and flow resistance of the wastewater, and makes it easier for flocculent matter to settle or be captured, thereby increasing filtration throughput and overall treatment efficiency.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Please see Figures 1-4 One embodiment of the present invention is: a wastewater filtration and recovery device for dried scallop processing, comprising a wastewater filtration tower 1, an inlet 2 and an outlet 3 fixedly connected inside the wastewater filtration tower 1, a filter plate 4 and a filter plate 5 fixedly connected inside the wastewater filtration tower 1, a motor 6 fixedly connected to the wastewater filtration tower 1, the output end of the motor 6 fixedly penetrating the outer wall of the wastewater filtration tower 1, a reciprocating screw 7 fixedly connected to the output end of the motor 6, a storage groove opened inside the reciprocating screw 7, a sliding groove opened inside the wastewater filtration tower 1, and the wastewater filtration and recovery device for dried scallop processing further comprising an impurity recovery mechanism installed on the reciprocating screw 7 and a chemical spraying mechanism installed inside the wastewater filtration tower 1; The impurity recovery mechanism includes a capture shell 8 mounted on a reciprocating screw 7, a rotating rod 9 mounted inside the capture shell 8, a gear 10 mounted on the rotating rod 9, a waste residue rotating plate 11 mounted on the rotating rod 9, a rotating ring 13 mounted on the rotating rod 9, and a toothed ring 12 mounted in the chute of the wastewater filter tower 1. The capture shell 8 is in contact with the outer wall of the filter plate 4, the rotating ring 13 is in contact with the chute of the wastewater filter tower 1, the outer wall of the waste residue rotating plate 11 is in contact with the filter plate 4, the gear 10 meshes with the toothed ring 12, and the circumferential surface of the rotating ring 13 is in contact with the toothed ring 12.

[0028] The rotation of the reciprocating screw 7 drives the capture shell 8 to rotate, which in turn drives the rotating rod 9 to rotate. The rotating rod 9 drives the gear 10 to rotate, and the gear 10 meshes with the gear ring 12. At this time, the gear 10 rotates on its own axis, which in turn drives the rotating rod 9 to rotate. The rotating rod 9 then drives the waste residue rotating plate 11 to rotate. The waste residue rotating plate 11 contacts the filter plate 4 and scrapes off the adhering residue, thus rotating and turning the waste residue into the interior of the capture shell 8. At this time, the wastewater will be filtered through the filter plate 4 to the middle partition, and then through the filter plate 5 for secondary filtration. Finally, the filtered wastewater is discharged through the outlet 3. This process can clean the blockage on the surface of the filter plate in real time, maintain the permeability of the filter holes, ensure the continuous and stable operation of the device, avoid production line interruptions caused by frequent shutdowns for cleaning, improve the overall wastewater treatment efficiency, prevent corrosive substances from adhering to the surface of the filter plate for a long time, delay the aging of the filter material, extend its service life, and reduce the overall cost of filter material replacement and manual maintenance.

[0029] The chemical spraying mechanism includes a chemical box 14 installed in the wastewater filter tower 1, a chemical inlet pipe 15 installed in the wastewater filter tower 1, a reciprocating screw 16 installed in the wastewater filter tower 1, a piston plate 17 installed in the reciprocating screw 1, a baffle 18 installed on the piston plate 17, and a spray box 19 installed on the reciprocating screw 1.

[0030] The reciprocating screw 17 has a medicine inlet, the medicine box 14 is in contact with the circumferential surface of the reciprocating screw 17, the circumferential surface of the reciprocating screw 2 16 is slidably embedded with the piston plate 17, the outer wall of the baffle 18 is in contact with the reciprocating screw 17, and a one-way valve is installed in the spray box 19.

[0031] The rotation of reciprocating screw 7 drives piston plate 17 to rotate. The rotation of piston plate 17 causes it to reciprocate through a groove on the circumferential surface of reciprocating screw 16. This reciprocating movement of piston plate 17 simultaneously drives baffle 18 to reciprocate, closing the inlet of reciprocating screw 7 and creating a closed space. At this point, the downward movement of piston plate 17 compresses the agent within the closed space, allowing it to enter the spray box 19 through reciprocating screw 7. Further compression of the agent inside spray box 19, while simultaneously opening a one-way valve... When the valve sprays the agent, the piston plate 17 moves upward, which simultaneously drives the baffle 18 to move upward. The baffle 18 moves to open the inlet, allowing the agent box 14 to continue to feed the agent into the reciprocating screw 7. The reciprocating screw 7 then delivers the agent to the spray box 19. At the same time, the one-way valve is closed to prevent agent leakage, achieving intermittent spraying. This avoids continuous excessive agent addition, allowing the agent to combine with wastewater to form flocs, improving the filtration and retention effect. Instead of continuous spraying, it avoids agent waste or excessive floc aggregation that clogs the filter pores. This achieves automated and precise agent addition, reducing manual intervention.

[0032] In addition, it should be noted that a power supply device and a processor can also be provided in this application. The power supply device supplies power to the motor 6, heater 219 and other functions, and the processor controls the motor 6 and heater 219. As an example, the power supply device can be a battery pack or municipal power supply equipment, and the processor is an existing device. This embodiment will not be described in detail. In this embodiment, the electrical connection of each device adopts a conventional continuous connection method.

[0033] In this embodiment, during operation: After the dried scallop shreds are processed, the equipment will generate a large amount of wastewater. At this time, the operator needs to connect the drain pipe to the inlet 2 and open the wastewater valve to allow the wastewater to enter the wastewater filter tower 1 through the inlet 2. When the wastewater enters the wastewater filter tower 1, it will first pass through the filter plate 4 to filter impurities. At the same time as filtration, the motor 6 will start working. The operation of the motor 6 will drive the reciprocating screw 7 to rotate through the output end. The rotation of the reciprocating screw 7 will drive the capture shell 8 to rotate. The rotation of the capture shell 8 will drive the rotating rod 9 to rotate. The rotating rod 9 will drive the gear 10 to rotate. The rotation of the gear 10 will mesh with the gear ring 12. At this time, the gear 10 will rotate on its own axis. The rotation of the gear 10 will drive the rotating rod 9 to rotate. The rotation of the rotating rod 9 will drive the waste residue rotating plate 11 to rotate. The filter plate 4 is rotated to remove the adhering residue, which is then rotated and turned into the inside of the capture shell 8. At this time, the wastewater will be filtered through the filter plate 4 to the middle partition, and then through the filter plate 5 for secondary filtration. Finally, the filtered wastewater is discharged through the outlet 3. This process can clean the blockage on the surface of the filter plate in real time, maintain the permeability of the filter pores, ensure the continuous and stable operation of the device, avoid production line interruptions caused by frequent shutdowns for cleaning, improve the overall wastewater treatment efficiency, prevent corrosive substances from adhering to the surface of the filter plate for a long time, delay the aging of the filter material, extend its service life, and reduce the overall cost of filter material replacement and manual maintenance. After the wastewater is purified by the equipment in multiple stages, harmful substances are greatly reduced, the river water is no longer black and smelly, the surrounding water environment is improved, water pollution is reduced, water quality safety and aquatic ecology are protected, the living environment is improved, water resources are saved, and human health is protected. While performing rotary filtration, the purifying agent is first injected into the medicine box 14 through the medicine inlet pipe 15, and then enters the internal storage tank of the reciprocating screw 7 through the medicine inlet of the medicine box 14. At this time, the rotation of the reciprocating screw 7 drives the piston plate 17 to rotate. The rotation of the piston plate 17 will contact the reciprocating groove on the circumferential surface of the reciprocating screw 16, thereby driving the piston plate 17 to reciprocate. The reciprocating movement of the piston plate 17 will simultaneously drive the baffle 18 to reciprocate, thereby closing the medicine inlet of the reciprocating screw 7 and creating a closed space. At this time, the downward movement of the piston plate 17 will compress the agent in the closed space, and the agent will enter the interior of the spray box 19 through the reciprocating screw 7. At this time, while continuing to compress the agent inside the spray box 19, the one-way valve is opened to spray the agent. When the piston plate 17 moves upward, it will simultaneously drive the baffle 18 to move upward. The baffle 18 moves to open the inlet, so that the agent box 14 continues to input the agent into the reciprocating screw 7, and then the reciprocating screw 7 delivers the agent into the spray box 19. At the same time, the one-way valve is closed to prevent the agent from leaking, realizing intermittent spraying. This avoids continuous excessive agent addition, allowing the agent to combine with the wastewater to form flocs, improving the filtration and interception effect. Instead of continuous spraying, it avoids agent waste or excessive floc accumulation that clogs the filter holes. This can realize the automation and precision of agent addition, reducing manual intervention.

[0034] Example 2: Please see Figures 5-6 Based on the above embodiments, in another embodiment of the present invention, the wastewater filtration and recovery device further includes a capture mechanism 20 installed on the capture shell 8, which is used to knock off the impurities on the filter plate 4. The capture mechanism 20 includes a positioning block 201 installed on the outer wall of the capture shell 8, a sliding rod 202 installed in the positioning block 201, a pulley 203 installed in the sliding rod 202, a striking block 204 installed on the sliding rod 202, and a trapezoidal block 205 installed in the wastewater filter tower 1.

[0035] The rotation of the capture shell 8 causes the positioning block 201 to rotate, which in turn causes the sliding rod 202 to rotate. The sliding rod 202 then causes the striking block 204 to rotate. Simultaneously, the sliding rod 202 causes the pulley 203 to rotate. The rotating pulley 203 contacts the inclined surface of the trapezoidal block 205 via its circumferential surface, allowing it to move along the inclined surface. This movement of the pulley 203, in turn, causes the sliding rod 202 to rotate, compressing a spring and causing the striking block 204 to move. The movement of the striking block 204 then... The outer wall of filter plate 4 is struck. When pulley 203 leaves trapezoidal block 205, trapezoidal block 205 will be reset by spring between it and positioning block 201, thereby resetting striking block 204. This facilitates the next striking of filter plate 4. The vibration and impact force can break the adhesion between filter cake and filter plate, causing the filter cake layer to loosen and fall off, quickly clearing blocked filter holes, restoring the permeability of filter plate, avoiding the decrease in filtration efficiency caused by filter hole blockage, and reducing equipment operation and maintenance costs. The capture mechanism 20 also includes an anti-clogging mechanism installed on the reciprocating screw 7, which is used to capture impurities and flocculent matter in the wastewater; The anti-clogging mechanism includes a connecting block 206 mounted on the reciprocating lead screw 7, a fixing frame 207 mounted on the connecting block 206, and an activated carbon plate 208 mounted in the fixing frame 207.

[0036] The rotation of the reciprocating screw 7 will drive the connecting block 206 to rotate, which in turn will drive the fixed frame 207 to rotate, and the fixed frame 207 to rotate the activated carbon plate 208. The rotation of the activated carbon plate 208 will capture the waste residue and flocculent matter in the wastewater, achieving efficient capture throughout the entire flow channel. This significantly reduces the risk of clogging of subsequent filter plates and the pollutant load of biochemical treatment, avoids local clogging, ensures continuous and stable operation of the device in high-concentration flocculent wastewater treatment scenarios, and reduces downtime and cleaning time costs.

[0037] The outer wall of the trapezoidal block 205 has an inclined surface, and the trapezoidal block 205 contacts the inclined surface of the pulley 203.

[0038] In this embodiment, during the capture of waste residue, the capture shell 8 rotates, causing the positioning block 201 to rotate. The positioning block 201 then rotates the sliding rod 202, which in turn rotates the striking block 204. Simultaneously, the sliding rod 202 rotates the pulley 203. The rotating pulley 203 contacts the inclined surface of the trapezoidal block 205 via its circumferential surface. The pulley 203 moves along the inclined surface of the trapezoidal block 205, causing the sliding rod 202 to rotate. The sliding rod 202 compresses the spring, causing the striking block 204 to move and strike. The movement of block 204 will strike the outer wall of filter plate 4. When pulley 203 leaves trapezoidal block 205, trapezoidal block 205 will be reset by the spring between it and positioning block 201, thereby driving striking block 204 to reset, so that filter plate 4 can be struck again. The vibration and impact force can break the adhesion between filter cake and filter plate, causing filter cake layer to loosen and fall off, quickly clearing blocked filter holes, restoring the permeability of filter plate, avoiding the decrease in filtration efficiency caused by filter hole blockage, and reducing equipment operation and maintenance costs. While the purifying agent is being sprayed, the wastewater will produce flocculent matter. The rotation of the reciprocating screw 7 will drive the connecting block 206 to rotate, which in turn will drive the fixed frame 207 to rotate. The rotation of the fixed frame 207 will drive the activated carbon plate 208 to rotate. The rotation of the activated carbon plate 208 will capture the waste residue and flocculent matter in the wastewater, achieving efficient capture throughout the entire flow channel. This significantly reduces the risk of clogging of subsequent filter plates and the pollutant load of biochemical treatment, avoids local clogging, ensures continuous and stable operation of the device in high-concentration flocculent wastewater treatment scenarios, and reduces downtime and cleaning time costs.

[0039] Example 3: Please see Figures 7-9 Based on the above embodiments, in another embodiment of the present invention, the wastewater filtration and recycling device further includes an auxiliary mechanism 21 installed in the fixed frame 207 to increase the waste residue capture area of ​​the fixed frame 207. The auxiliary mechanism 21 includes a rotating rod 211 installed in the fixed frame 207, a capture plate 212 installed on the rotating rod 211, a telescopic hinge rod 213 installed on the rotating rod 211, a connecting rod 214 installed on the telescopic hinge rod 213, a roller 215 installed on the connecting rod 214, and a cam 216 installed on the filter plate 25.

[0040] The rotation of the fixed frame 207 drives the rotating rod 211 to rotate, which in turn drives the capturing plate 212 to rotate. The rotation of the capturing plate 212 drives the telescopic hinge rod 213 to rotate, which in turn drives the connecting rod 214 to rotate. The connecting rod 214 then drives the roller 215 to rotate. The rotating roller 215 contacts the cam 216 through its circumferential surface, thus moving the roller 215. The roller 215 then moves the connecting rod 214, which in turn causes the telescopic hinge rod 213 to rotate and retract. Simultaneously, the rotating rod 211 drives the capturing plate 212 to rotate, thereby... The flocculent matter and residue in the wastewater are captured. When the roller 215 leaves the cam 216, the connecting rod 214 is reset by the torsion spring between the rotating rod 211 and the fixed frame 207. At the same time, the rotating rod 211 drives the capture plate 212 to reset, which facilitates reciprocating rotation and capture. The efficient capture can effectively remove suspended solids and some organic matter in the wastewater. The concentration of suspended solids in the treated effluent is significantly reduced, and it can be directly reused in production processes such as scallop washing and equipment rinsing, reducing the use of fresh water resources. Even if discharged, it can easily meet the wastewater discharge standards of the aquatic product processing industry.

[0041] The auxiliary mechanism 21 also includes a heating mechanism installed on the reciprocating lead screw 7 for controlling the wastewater temperature; The heating mechanism includes a limiting rod 217 installed in the wastewater filter tower 1, a ring 218 installed on the reciprocating screw 7, and a heater 219 installed on the ring 218.

[0042] During wastewater treatment, the rotation of the reciprocating screw 7 will drive the reciprocating slide groove on the circumferential surface to rotate, thereby driving the ring 218 to move back and forth. The ring 218 will move along the limiting rod 217, and the ring 218 will drive the heater 219 to move back and forth. At this time, the heater 219 is activated to heat the wastewater by moving back and forth, thereby improving the wastewater treatment efficiency, reducing the viscosity and flow resistance of the wastewater, and making it easier for impurities such as flocs, shell powder, and dried scallop fragments formed by flocculation to settle or be intercepted by the capture structure. At the same time, the low viscosity water flow can reduce the adhesion and blockage of suspended solids in the pores of the filter plate, and improve the filtration flux and overall treatment efficiency.

[0043] A torsion spring is provided between the rotating rod 211 and the fixed frame 207, the capturing plate 212 contacts the fixed frame 207, the roller 215 contacts the cam 216, and the circumferential surface of the limiting rod 217 is slidably embedded in the ring 218.

[0044] In this embodiment, during operation: while the activated carbon plate 208 captures the flocculent matter, the fixed frame 207 rotates, causing the rotating rod 211 to rotate. The rotating rod 211 then rotates the capturing plate 212, which in turn rotates the telescopic hinge rod 213. The telescopic hinge rod 213 then rotates the connecting rod 214, which in turn rotates the roller 215. The rotating roller 215 contacts the cam 216 through its circumferential surface, thus moving the roller 215. The roller 215 then moves the connecting rod 214, which in turn causes the telescopic hinge rod 213 to rotate and retract. Simultaneously, the rotating rod 211... The moving capture plate 212 rotates to capture flocculent matter and residue in the wastewater. When the roller 215 leaves the cam 216, the connecting rod 214 is reset by the torsion spring between the rotating rod 211 and the fixed frame 207. At the same time, the rotating rod 211 drives the capture plate 212 to reset, which facilitates reciprocating rotation and capture. The efficient capture can effectively remove suspended solids and some organic matter in the wastewater. The concentration of suspended solids in the treated effluent is significantly reduced, and it can be directly reused in production processes such as scallop washing and equipment rinsing, reducing the use of fresh water resources. Even if discharged, it can easily meet the wastewater discharge standards of the aquatic product processing industry. During wastewater treatment, the rotation of the reciprocating screw 7 will drive the reciprocating slide groove on the circumferential surface to rotate, thereby driving the ring 218 to move back and forth. The ring 218 will move along the limiting rod 217, and the ring 218 will drive the heater 219 to move back and forth. At this time, the heater 219 is activated to heat the wastewater by moving back and forth, thereby improving the wastewater treatment efficiency, reducing the viscosity and flow resistance of the wastewater, and making it easier for impurities such as flocs, shell powder, and dried scallop fragments formed by flocculation to settle or be intercepted by the capture structure. At the same time, the low viscosity water flow can reduce the adhesion and blockage of suspended solids in the pores of the filter plate, and improve the filtration flux and overall treatment efficiency.
