[0032] The embodiment of the present application discloses an aquaculture wastewater filtering device 100.

[0033] Reference Figure 1 and Figure 2According to the aquaculture wastewater filtering device 100 described in the embodiment of the present application, it includes: a filtering assembly 10, a collecting box 103 and a cleaning mechanism 20. The filtering assembly 10 includes an equipment body 101 and a filter 102, the equipment body 101 defines an installation space 1011, and the filter 102 is constructed as a cylindrical member and is arranged in the equipment body 101. In addition, the filter 102 is spaced apart from the inner peripheral wall of the equipment body 101 to form a filtering gap 1012, the side wall of the filter 102 has a filtering hole 1021 penetrating the filter 102, and the filtering hole 1021 is connected to the filtering gap 1012, the filter 102 is provided with a water inlet 1022 connected to the filter 102, the equipment body 101 is provided with a water outlet 1013 connected to the filtering gap 1012, and the filter 102 is used to filter the feed and feces and other debris in the aquaculture wastewater.

[0034] Specifically, along the height direction of the aquaculture wastewater filtration device 100, the water inlet 1022 can be set at the upper end or the lower end of the inner wall of the filter element 102, and the water outlet 1013 can be set at the upper end or the lower end of the side wall of the device body 101. The aquaculture wastewater flows into the filter element 102 through the water inlet 1022, and the liquid in the filter element 102 flows into the filter gap 1012 through the filter hole 1021 and then flows out from the water outlet 1013. The height direction of the aquaculture wastewater filtration device 100 can refer to Figure 1 The up and down directions in .

[0035] Furthermore, the filter element 102 has a plurality of filter holes 1021, which are spaced apart along the height direction of the aquaculture wastewater filtering equipment 100 and spaced apart along the circumferential direction of the filter element 102. The plurality of filter holes 1021 jointly filter the aquaculture wastewater, thereby improving the filtering efficiency of the aquaculture wastewater filtering equipment 100.

[0036] Furthermore, there can be multiple water inlets 1022 and water outlets 1013, and the multiple water inlets 1022 are arranged in sequence along the circumferential direction of the filter element 102, and the multiple water outlets 1013 are spaced apart along the height direction of the aquaculture wastewater filtration equipment 100, and are arranged in sequence along the circumferential direction of the aquaculture wastewater filtration equipment 100.

[0037] The collecting box 103 is disposed at the bottom of the filter assembly 10 and is in communication with the filter element 102 . The collecting box 103 is used to collect sundries such as feed and feces in the filter element 102 .

[0038] In addition, the cleaning mechanism 20 is arranged on the equipment body 101, and the cleaning mechanism 20 includes a first driving component 201 and a cleaning component 203. The first driving component 201 is connected and cooperated with the equipment body 101, and the cleaning component 203 is connected and cooperated with the first driving component 201, and the cleaning component 203 is located in the filter element 102. The cleaning component 203 includes a plurality of cleaning components 2031, and the plurality of cleaning components 2031 are all abutted against the inner circumferential wall of the filter element 102, and the plurality of cleaning components 2031 are arranged in sequence along the circumferential direction of the filter element 102, that is, the inner circumferential wall of the filter element 102 is covered by the plurality of filter elements 102, and the cleaning component 203 switches between the first working mode and the second working mode when driven by the first driving component 201.

[0039] Reference Figure 4 In the first working mode, the cleaning member 2031 is arranged to extend downwardly and obliquely along the height direction of the aquaculture wastewater filtration equipment 100, that is, there is an angle between the upper end surface of the cleaning member 2031 and the horizontal plane, and the first driving assembly 201 is used to drive the cleaning member 2031 to rotate along the inner circumferential wall of the filter element 102 around the central axis of the filter element 102.

[0040] Specifically, an annular groove (not shown in the drawings) is provided at the upper end of the cleaning piece 2031, and bristles (not shown in the drawings) are provided in the annular groove. The bristles abut against the inner circumferential wall of the cleaning piece 2031 to clean the debris adhered to the inner circumferential wall of the cleaning piece 2031. The first driving component 201 drives the cleaning piece 2031 to clean the inner circumferential wall of the filter element 102, so that the debris such as feed and feces adhered to the inner circumferential wall of the filter element 102 are separated from the inner circumferential wall of the filter element 102, thereby avoiding as much as possible the adhesion of a large amount of debris such as feed and feces to the inner circumferential wall of the filter element 102, and avoiding as much as possible the clogging of the filter hole 1021 of the filter element 102 by debris such as feed and feces, thereby reducing the number of times the operator cleans the inner circumferential wall of the filter element 102.

[0041] Furthermore, when the first driving component 201 drives the cleaning member 2031 to rotate, the cleaning member 2031 stirs the liquid in the filter element 102 and forms a vortex from top to bottom in the filter element 102, and the debris separated from the inner peripheral wall of the filter element 102 is absorbed by the vortex and moves away from the inner peripheral wall of the filter element 102, thereby minimizing the debris in the aquaculture wastewater from re-adhering to the inner peripheral wall of the filter element 102. Furthermore, under the action of the vortex, part of the debris is transferred to the collection box 103, thereby reducing the amount of debris in the filter element 102, and further extending the time interval for workers to clean the filter element 102.

[0042] Furthermore, the first driving component 201 can drive the cleaning member 2031 to move along the height direction of the aquaculture wastewater filtering equipment 100 , and the filtering holes 1021 located at different heights of the filtering member 102 can all be cleaned by the cleaning member 2031 .

[0043] Reference Figure 5 and Figure 6 In the second working mode, multiple cleaning members 2031 are horizontally arranged to divide the filter element 102 into a first chamber 1023 and a second chamber 1024. Specifically, the first chamber 1023 is located on the side of the cleaning member 2031 away from the collecting box 103, and the second chamber 1024 is located on the side of the cleaning member 2031 close to the collecting box 103. The first driving component 201 is used to drive the cleaning member 2031 to move along the height direction of the aquaculture wastewater filtration equipment 100. When the cleaning component 203 moves along the height direction of the aquaculture wastewater filtration equipment 100, the space size of the first chamber 1023 and the space size of the second chamber 1024 both change with the movement position of the cleaning member 2031.

[0044] Specifically, when the cleaning piece 2031 has completed cleaning the debris adhered to the inner wall of the filter element 102, and there is a large amount of debris near the center position of the filter element 102 along the radial direction of the filter element 102, the staff controls the first drive assembly 201 to drive the cleaning piece 2031 to switch to the second working mode, and multiple cleaning pieces 2031 are connected end to end in sequence to form a ring structure, and the first drive assembly 201 drives the cleaning piece 2031 to move close to the collection box 103 to press the debris under the cleaning piece 2031 into the collection box 103, thereby avoiding an excessive amount of debris in the filter element 102 as much as possible, and avoiding the filter hole 1021 of the filter element 102 being repeatedly blocked by debris, thereby improving the filtration efficiency of the aquaculture wastewater filtration equipment 100.

[0045] When the debris in the collection box 103 accumulates to a preset amount, the staff discharges the liquid in the filter element 102 out of the device body 101 , and then the staff cleans the debris in the collection box 103 .

[0046] It should be noted that before the cleaning member 2031 switches to the second working mode, the first drive component 201 drives the cleaning member 2031 to move close to the upper end of the equipment body 101. When the cleaning member 2031 moves close to the upper end of the equipment body 101 to the preset switching position, the first drive component 201 drives the cleaning member 2031 to switch to the second working mode. The designer can set the preset switching position according to the liquid level height of the liquid in the filter element 102.

[0047] Thus, the first driving component 201 drives the cleaning member 2031 to switch to the first working mode, and the cleaning member 2031 cleans the debris adhering to the inner peripheral wall of the filter element 102, and the first driving component 201 drives the cleaning member 2031 to switch to the second working mode, and the cleaning member 2031 presses the debris in the filter element 102 into the collection box 103. Compared with the prior art, the aquaculture wastewater filtering device 100 can avoid the filter element 102 from being blocked by debris such as feed and feces as much as possible, thereby improving the filtering efficiency of the aquaculture wastewater filtering device 100.

[0048] Reference Figure 2-Figure 5 In some embodiments of the present application, the first driving assembly 201 includes a first driving member 2011, a second driving member 2012 and a transmission rod 2013, and the first driving member 2011, the second driving member 2012 and the transmission rod 2013 are connected and matched in sequence. Specifically, the first driving member 2011 is located above the second driving member 2012, and the transmission rod 2013 is located below the second driving member 2012, and the first driving member 2011 and the second driving member 2012 are both spaced apart from the filter element 102, thereby preventing the liquid in the filter element 102 from damaging the first driving member 2011 and / or the second driving member 2012, thereby improving the working reliability of the aquaculture wastewater filtration equipment 100.

[0049] In addition, the transmission rod 2013 is extended along the height direction of the aquaculture wastewater filtering equipment 100, and one end of the transmission rod 2013 away from the second driving member 2012 extends into the filter element 102 to connect with the cleaning component 203, and a seal is set between the transmission rod 2013 and the equipment body 101. Specifically, a sealing ring is set at the connection between the equipment body 101 and the transmission rod 2013.

[0050] Furthermore, one of the first driving member 2011 and the second driving member 2012 is used to drive the second driving member 2012 to drive the cleaning member 2031 to rotate around the central axis of the filter element 102, and the other of the first driving member 2011 and the second driving member 2012 is used to drive the cleaning member 2031 to move along the height direction of the aquaculture wastewater filtration equipment 100.

[0051] In some specific embodiments, the first driving member 2011 drives the second driving member 2012 to drive the cleaning member 2031 to rotate around the central axis of the filter element 102, and the second driving member 2012 drives the cleaning member 2031 to move along the height direction of the aquaculture wastewater filtration equipment 100. The first driving member 2011 can be a motor, and the second driving member 2012 can be a cylinder, but the present application is not limited to this. The first driving member 2011 can be a hydraulic motor, and the second driving member 2012 can be a hydraulic cylinder, etc.

[0052] Specifically, when the cleaning member 2031 is in the first working mode, the first driving member 2011 drives the second driving member 2012 to drive the cleaning member 2031 to rotate, so that the cleaning member 2031 can clean the debris adhered to the filter element 102, and the second driving member 2012 drives the cleaning member 2031 to move along the height direction of the aquaculture wastewater filtering device 100, so that the filter holes 1021 at different heights of the filter element 102 can be cleaned by the cleaning member 2031. When the cleaning member 2031 is in the second working mode, the second driving member 2012 drives the cleaning member 2031 to move along the height direction of the aquaculture wastewater filtering device 100, so that the cleaning member 2031 can press the debris in the filter element 102 into the collection box 103.

[0054] Furthermore, there are multiple avoidance holes 2018 and connecting rods 2017, and the multiple connecting rods 2017 and the multiple avoidance holes 2018 are spaced apart along the circumferential direction of the shell 2015, and the multiple connecting rods 2017 and the multiple avoidance holes 2018 are arranged one-to-one correspondingly with the multiple cleaning parts 2031.

[0055] The third driving member 2016 is used to drive the connecting rod 2017 to drive the cleaning member 2031 to rotate around the central axis of the connecting rod 2017, so that the cleaning member 2031 can switch between the first working mode and the second working mode.

[0056] Furthermore, the transmission rod 2013 may be constructed as a hollow rod, and an external wire or a hydraulic fluid delivery pipe passes through the transmission rod 2013 to be connected and matched with the third driving member 2016 .

[0057] Specifically, when the cleaning member 2031 switches from the second working mode to the first working mode, the third driving member 2016 drives the connecting rod 2017 to drive the cleaning member 2031 to rotate so that the multiple cleaning members 2031 are all tilted. When the cleaning member 2031 switches from the first working mode to the second working mode, the third driving member 2016 drives the connecting rod 2017 to drive the cleaning member 2031 to rotate so that the multiple cleaning members 2031 are all horizontally set. It should be noted that the third driving member 2016 simultaneously drives multiple connecting rods 2017 to drive the corresponding cleaning members 2031 to rotate.

[0058] In other specific embodiments, the third driving member 2016 can be a stepping motor, and the staff can control the rotation angle of the cleaning member 2031 according to the number of pulses transmitted to the third driving member 2016, thereby achieving the technical effect of accurately controlling the rotation angles of multiple cleaning members 2031.

[0059] Reference Figure 3 In some embodiments of the present application, an output gear 2019 is provided at the output end of the third driving member 2016. Along the height direction of the aquaculture wastewater filtration equipment 100, the output end of the third driving member 2016 is located below the third driving member 2016, and an input gear 2020 is provided at the end of the connecting rod 2017 close to the third driving member 2016. The output gear 2019 is meshed and connected with the input gear 2020, so that the third driving member 2016 is suitable for driving the connecting rod 2017 to rotate around the central axis of the connecting rod 2017. In some specific embodiments, the output gear 2019 and the input gear 2020 can both be bevel gears.

[0060] The third driving member 2016 and the connecting rod 2017 are transmitted via gears, and the gear transmission has the characteristics of high precision and high stability, thereby improving the transmission reliability and transmission accuracy between the third driving member 2016 and the connecting rod 2017, and further improving the working reliability of the aquaculture wastewater filtration equipment 100.

[0061] Reference Figure 2 In some embodiments of the present application, in the second working mode, the side wall of the cleaning member 2031 away from the filter element 102 is spaced apart from the outer peripheral wall of the shell 2015 to form a movable gap 2032. The aquaculture wastewater filtration equipment 100 also includes a pressing component 30, and the pressing component 30 includes a pressing component 301 and a fourth driving component 302. The pressing component 301 is arranged in the filter element 102 and is located on the side of the cleaning member 2031 away from the collection box 103, and along the height direction of the aquaculture wastewater filtration equipment 100, the upper end wall of the pressing component 301 is suitable for abutting against the inner top wall of the equipment body 101. The fourth driving component 302 is arranged at the upper end of the equipment body 101 and is connected and cooperated with the pressing component 301. The fourth driving component 302 is spaced apart from the liquid in the filter element 102, so as to minimize the damage of the fourth driving component 302 by the liquid. In some specific embodiments, the fourth driving component 302 can be a cylinder, but the present application is not limited to this. The fourth driving component 302 can also be a hydraulic cylinder, etc.

[0062] Furthermore, the fourth driving member 302 is configured to drive the pressing member 301 to move close to the cleaning member 2031 when the cleaning member 2031 is in the second working mode, so that the pressing member 301 and the cleaning member 2031 are stopped, and the pressing member 301 is used to block the movable gap 2032.

[0063] Specifically, when the cleaning member 2031 is in the first working mode, the stop member abuts against the inner top wall of the equipment body 101; when the cleaning member 2031 is in the second working mode, the fourth driving member 302 drives the stop member to move close to the cleaning member 2031 and abuts against the upper end of the cleaning member 2031 to block the active gap 2032; then the fourth driving member 302 and the second driving member 2012 work simultaneously to drive the pressing member 301 and the cleaning member 2031 to move close to the collecting box 103 at the same time; the pressing member 301 and multiple cleaning members 2031 jointly press the debris in the filter element 102 into the collecting box 103, thereby avoiding as much as possible the debris in the filter element 102 from passing through the active gap 2032 and entering the first chamber 1023, thereby minimizing the amount of debris in the filter element 102, and further preventing the filter hole 1021 of the filter element 102 from being frequently blocked by debris, thereby further improving the filtration efficiency of the aquaculture wastewater filtration equipment 100.

[0064] Reference Figure 2In some embodiments of the present application, a drain outlet 1014 is provided at the bottom end of the equipment body 101 along the height direction of the aquaculture wastewater filtration equipment 100. The drain outlet 1014 connects the inside of the filter element 102 and the outside of the equipment body 101. The liquid in the filter element 102 flows out to the outside of the equipment body 101 through the drain outlet 1014. The drain outlet 1014 is provided with a drain valve 1015. In some specific embodiments, the drain valve 1015 can be a gate valve, but the present application is not limited to this. The drain valve 1015 can also be a ball valve, etc.

[0065] It should be noted that a filter screen is provided at the end of the drain port 1014 close to the filter element 102 , and the filter screen is used to filter debris. The diameter of the drain port 1014 is relatively large, so that the liquid in the filter element 102 can be quickly discharged to the outside of the equipment body 101 .

[0066] Specifically, when the cleaning member 2031 is in the first working mode, the drain valve 1015 closes the drain port 1014. When the cleaning member 2031 is in the second working mode, the drain valve 1015 opens the drain port 1014, and the liquid in the filter element 102 flows out of the equipment body 101 through the drain port 1014, thereby preventing the pressing member 301 and the cleaning member 2031 from squeezing the liquid in the filter element 102, and preventing the pressing member 301 and the cleaning member 2031 from being unable to move close to the collection box 103, thereby achieving the technical effect of the pressing member 301 and the cleaning member 2031 pressing the debris in the filter element 102 to the collection box 103.

[0067] Reference Figure 2 In some embodiments of the present application, the aquaculture wastewater filtration device 100 may further include: a turbidity detection element 40 and a controller. The turbidity detection element 40 is arranged on the inner peripheral wall of the filter element 102, and the turbidity detection element 40 is used to detect the turbidity of the liquid in the filter element 102. Specifically, the turbidity detection element 40 includes a laser emitting element 401 and a laser receiving element 402. The laser emitting element 401 and the laser receiving element 402 are arranged relatively, and the laser emitting element 401 is used to emit laser, and the laser receiving element 402 is used to receive laser. The laser emitting element 401 emits a light of a first light intensity to the laser receiving element 402, and the light passes through the debris in the filter element 102 and is received by the laser receiving element 402. The laser receiving element 402 generates a second light intensity according to the light intensity of the received light, and obtains the turbidity of the liquid by calculating the difference between the first light intensity and the second light intensity. In some specific embodiments, the laser emitting element 401 can be a laser diode, and the laser receiving element 402 can be a photodetector.

[0068] Furthermore, the turbidity detection element 40 and the first drive assembly 201 are both communicatively connected to the controller, and the controller is configured to control the first drive assembly 201 to drive the cleaning assembly 203 to switch to the first working mode when the turbidity detected by the turbidity detection element 40 is not less than a preset turbidity.

[0069] Specifically, when the turbidity of the liquid in the filter element 102 is higher than the preset turbidity, that is, the amount of debris in the filter element 102 is large, the third driving member 2016 drives the cleaning member 2031 to switch to the first working mode, and the first driving member 2011 drives the cleaning member 2031 to rotate and form a vortex in the filter element 102. Part of the debris in the filter element 102 is absorbed by the vortex and transported to the collection box 103, thereby reducing the amount of debris in the filter element 102, and further avoiding the filter hole 1021 of the filter element 102 being repeatedly blocked by debris, which can further improve the filtration efficiency of the aquaculture wastewater filtration equipment 100.

[0070] Furthermore, the turbidity includes a first preset turbidity and a second preset turbidity, and the first preset turbidity is less than the second preset turbidity. When the turbidity of the liquid in the filter element 102 is between the first preset turbidity and the second preset turbidity, the controller controls the third driving element 2016 to drive the cleaning element 2031 to switch to the first working mode.

[0071] When the turbidity of the liquid in the filter element 102 is not less than the second preset turbidity, the controller controls the third driving member 2016 to drive the cleaning member 2031 to switch to the second working mode, and controls the fourth driving member 302 to drive the pressing member 301 to move close to the cleaning member 2031. Specifically, the third driving member 2016 first drives the cleaning member 2031 to switch to the second working mode, and then the fourth driving member 302 drives the pressing member 301 to move close to the cleaning member 2031 and stop with the cleaning member 2031. Finally, the second driving member 2012 and the fourth driving member 302 work simultaneously, and the pressing member 301 and multiple cleaning members 2031 move synchronously close to the collecting box 103 to press the debris in the filter element 102 into the collecting box 103, thereby further reducing the amount of debris in the filter element 102, avoiding the filter holes 1021 of the filter element 102 being repeatedly blocked by debris, and further improving the filtration efficiency of the aquaculture wastewater filter element 102.

[0072] The turbidity of the liquid in the filter element 102 is detected by the turbidity detection element 40, and the controller controls the third driving element 2016 to drive the cleaning element 2031 to switch to the first working mode according to the detection signal of the turbidity detection element 40. Multiple cleaning elements 2031 jointly clean the inner wall of the filter element 102, thereby improving the automation degree of the aquaculture wastewater filtration equipment 100, reducing the work intensity of the staff, and further improving the use experience of the aquaculture wastewater filtration equipment 100.

[0073] Furthermore, there may be a plurality of turbidity detection elements 40, which are spaced apart in the height direction of the aquaculture wastewater filtration equipment 100. The controller is also used to control the second driving element 2012 to drive the cleaning element 2031 to move to the corresponding turbidity detection element 40 according to the detection signal of the corresponding turbidity detection element 40. The first driving element 2011 drives the cleaning element 2031 to rotate to form an eddy current in the filter element 102. The eddy current transports part of the debris at the corresponding turbidity detection element 40 to the collecting box 103, thereby avoiding the filter holes 1021 near the turbidity detection element 40 from being repeatedly blocked by debris as much as possible, thereby further improving the filtration efficiency of the aquaculture wastewater filtration equipment 100.

[0074] Reference Figure 2 In some embodiments of the present application, the aquaculture wastewater filtration device 100 may further include: a water level detection member 50. The water inlet 1022 is provided with a water inlet control valve 1025, and the water level detection member 50 is provided on the filter element 102 and is used to detect the liquid level of the liquid in the filter element 102. In some specific embodiments, the water inlet control valve 1025 may be a ball valve, and the water level detection member 50 may be an optical liquid level sensor, but the present application is not limited thereto, and the water inlet control valve 1025 may also be a butterfly valve, etc., and the water level detection member 50 may also be a resistance-type liquid level sensor, etc.

[0075] Specifically, when the water level detection member 50 is configured as an optical liquid level sensor, the water level detection member 50 can be disposed on the top wall of the filter element 102 ; when the water level detection member 50 is configured as a resistance-type liquid level sensor, the water level detection member 50 can be disposed on the inner circumferential wall of the filter element 102 .

[0076] In addition, the water level detection element 50 and the water inlet control valve 1025 are both communicatively connected to the controller, and the controller is constructed to control the water inlet control valve 1025 to open when the liquid level in the filter element 102 is lower than a first preset water level, and to control the water inlet control valve 1025 to close when the liquid level in the filter element 102 is higher than a second preset water level, wherein the first preset water level is lower than the second preset water level.

[0077] The controller controls the water inlet control valve 1025 to be opened or closed according to the detection signal of the water level detection component 50. Along the height direction of the aquaculture wastewater filtration equipment 100, a switching space without liquid is formed above the second preset water level. The cleaning component 2031 can switch the working mode in the switching space. Compared with the cleaning component 2031 switching the working mode in the liquid, such a setting can reduce the resistance encountered by the cleaning component 2031 when switching the working mode, thereby reducing the difficulty of the cleaning component 2031 switching the working mode, and further improving the efficiency of the cleaning component 2031 switching the working mode.

[0078] It should be noted that when the water level detection component 50 is constructed as a resistive liquid level sensor, there are at least two water level detection components 50, and the two water level detection components 50 are spaced apart along the height direction of the aquaculture wastewater filtration equipment 100, and the first preset water level height and the second preset water level height are both higher than the height of the water outlet 1013.

[0079] Reference Figure 1 and Figure 2 In some embodiments of the present application, the aquaculture wastewater filtration equipment 100 may also include: a pushing mechanism 60, the side wall of the collecting box 103 is provided with a discharge port 1031 connected to the collecting box 103, the discharge port 1031 is provided with a discharge cover 1032, the discharge cover 1032 is used to open or close the discharge port 1031, and the discharge cover 1032 is sealed with the discharge port 1031. In some specific embodiments, the discharge cover 1032 can be a gate type discharge cover 1032.

[0080] In other specific embodiments, the staff can manually operate the discharge cover 1032 to open or close the discharge port 1031. A discharge cover driving mechanism 1033 may also be provided in the collection box 103. The staff can drive the discharge cover 1032 to open or close the discharge port 1031 by controlling the discharge cover driving mechanism 1033. The discharge cover driving mechanism 1033 may be a cylinder, but the present application is not limited to this. The discharge cover driving mechanism 1033 may also be a hydraulic cylinder, etc.

[0081] In addition, the pushing mechanism 60 is arranged in the collection box 103, and the pushing mechanism 60 includes a pushing member 601 and a pushing plate 602. The pushing plate 602 is connected and cooperated with the pushing member 601. Specifically, the pushing member 601 is arranged on the outer wall of the collection box 103, and the pushing plate 602 is located in the collection box 103. The output end of the pushing member 601 passes through the collection box 103 and is connected and cooperated with the pushing plate 602, and the output end of the pushing member 601 is sealed with the collection box 103. The pushing member 601 is used to drive the pushing plate 602 to push the debris in the collection box 103 to move close to the discharge port 1031.

[0082] When the amount of debris in the collection box 103 is large, the staff controls the drain valve 1015 to open the drain port 1014 to drain the liquid in the filter element 102, and controls the third driving member 2016 to drive the cleaning member 2031 to switch to the second working mode, and controls the fourth driving member 302 to drive the pressing member 301 to move close to the cleaning member 2031 and stop with the cleaning member 2031, and then controls the fourth driving member 302 and the second driving member 2012 to work synchronously so that the pressing member 301 can move closer to the cleaning member 2031 and stop with the cleaning member 2031. 01 and multiple cleaning parts 2031 move synchronously towards the collection box 103. When the pressing part 301 and the cleaning part 2031 move to the connection between the collection box 103 and the filter element 102, the staff controls the discharge cover 1032 to open the discharge port 1031, and controls the pushing part 601 to drive the push plate 602 to move close to the discharge port 1031 to push the debris in the collection box 103 to the discharge port 1031, and the debris in the collection box 103 leaves the collection box 103 through the discharge port 1031.

[0083] The discharge port 1031 is opened by the discharge cover 1032, and the push plate 602 is driven by the push member 601 to push the debris in the collection box 103 to the discharge port 1031. The debris in the collection box 103 leaves the collection box 103 through the discharge port 1031. Compared with manually cleaning the debris in the collection box 103, such a setting can reduce the work intensity of the staff, thereby improving the use experience of the aquaculture wastewater filtration equipment 100.

[0084] Based on this, the present application further discloses a breeding wastewater treatment system.

Compared with the prior art, the aquaculture wastewater filtering device 100 can avoid the filter 102 from being blocked by debris such as feed and feces as much as possible, thereby improving the filtering efficiency of the aquaculture wastewater filtering device 100.
