Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture wastewater treatment, and particularly to an aquaculture wastewater purification and discharge device. Background Art

[0002] The aquaculture wastewater purification and discharge device is used to purify aquaculture wastewater, so as to realize the reuse of water resources or harmless discharge. The existing aquaculture wastewater purification and discharge devices generally adopt a method of regular cleaning, sucking aquaculture wastewater from the edge of the aquaculture pond, and purifying the aquaculture wastewater through a wastewater purification mechanism, which has the following several defects:

[0003] 1. Impurities such as sludge and particulate matter are generally deposited at various positions on the bottom surface of the aquaculture pond, and the impurities have a certain viscosity and weight. Even with a high-power suction device, it is difficult to suck all the impurities at various positions cleanly, and the newly injected aquaculture water will be quickly polluted.

[0004] 2. The treatment of aquaculture wastewater is generally divided into physical methods, chemical methods and biological methods. The physical method generally filters impurities through a filter. The existing filters usually use filter bags made of flexible materials when filtering small particulate impurities in aquaculture wastewater. The filter bag is sleeved outside the hollow mounting frame, and the wastewater flows from the inside to the outside of the mounting frame, and the impurities are intercepted inside the filter bag. On the one hand, the filter bag needs to be replaced frequently, which is inconvenient to use. On the other hand, the filter bag is continuously subjected to the outward impact force of the water flow, and is easy to separate from the mounting frame or even rupture, thereby losing the filtering effect.

[0005] In view of this, how to provide an aquaculture wastewater purification device that can solve the above defects is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide an aquaculture wastewater purification and discharge device to solve the problems existing in the prior art.

[0015] Further, the connecting pipe is made of a flexible material.

[0016] Further, the tail water purification system includes:

[0017] A primary filtration mechanism, which is communicated with the connecting pipe and is used for filtering particulate matters in the tail water;

[0024] A filtration component, which is arranged in the secondary filtration cylinder and is located between the second water inlet and the second water outlet.

[0025] Further, the filtration component includes: a first mounting rack, a second mounting rack, and a filter bag clamped between the first mounting rack and the second mounting rack, and both the first mounting rack and the second mounting rack are fixedly connected to the inner side wall of the secondary filtration cylinder.

[0026] Further, it further includes:

[0027] The base is arranged inside the secondary filter cylinder and close to the second water inlet. A first through hole is arranged through the upper and lower surfaces in the middle of the base.

[0028] The support member is fixedly arranged on the base. A second through hole is arranged through the upper and lower surfaces of the support member, and the second through hole is communicated with the first through hole.

[0029] The lower edges of the first mounting frame, the second mounting frame and the filter bag are all fixedly connected to the support member, and the first mounting frame, the second mounting frame and the filter bag are all hemispherical structures protruding upward. The lower surface of the second mounting frame corresponds to the second through hole.

[0030] Furthermore, a first sewage discharge pipe is arranged at the bottom of the primary filter cylinder, and a second sewage discharge pipe is arranged at the bottom of the secondary filter cylinder. The first sewage discharge pipe and the second sewage discharge pipe are both communicated with a screw press. A first sewage discharge valve is arranged on the first sewage discharge pipe, and a second sewage discharge valve is arranged on the second sewage discharge pipe.

[0031] Furthermore, it further includes:

[0032] A drain pipe is communicated with the first sewage discharge pipe. A drain valve is arranged on the drain pipe. An inlet valve is arranged at the second water inlet, and an outlet valve is arranged at the second water outlet.

[0034] The present invention discloses the following technical effects:

[0035] 1. The tail water suction mechanism is moved to any position above the aquaculture pond by using the transverse slide rail and the longitudinal slide rail, so that the tail water suction mechanism can comprehensively suck impurities in the aquaculture pond.

[0037] 3. Two-stage filter cylinders are provided in this application. The primary filter cylinder is used to filter large-particle impurities, and the secondary filter cylinder is used to filter small-particle impurities such as suspended matters. In the secondary filter cylinder, the filter bag is clamped between two mounting frames. When the tail water impacts the filter bag from bottom to top, most of the impact force can be borne by the mounting frame above the filter bag, and a small part of the impact force is borne by the filter bag itself, thereby improving the stability of the filter bag and avoiding the filter bag from bursting; in addition, the upper and lower clamping mounting frames can directly solve the problem of the separation of the filter bag from the mounting frame.

[0038] 4. This application is provided with a "backwashing" device. When the filter bag retains a large amount of impurities, the filter bag can be flushed from the outside to the inside through the flushing pipe, and the impurities on the inner surface of the filter bag are washed off and sink to the bottom of the secondary filter cylinder, and finally discharged through the drain pipe. During the backwashing process, the impact force on the filter bag becomes downward, and at this time, most of the impact force can be borne by the mounting frame set under the filter bag. In this way, the filter bag has sufficient stability and can be cleaned of impurities through backwashing, and no replacement is required, which solves the problem of the need to replace the filter bag of the existing filter.

Detailed Implementation Manner

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0051] The embodiment of the present invention provides a breeding tail water purification and discharge device, including: a horizontal slide rail 1 symmetrically arranged on the front and rear sides of the breeding pond 29 along the length direction of the breeding pond 29; a vertical slide rail 2 arranged along the width direction of the breeding pond 29 and slidably connected to the horizontal slide rail 1 through a first linear motor 3; the tail water suction mechanism is slidably connected to the vertical slide rail 2 through a second linear motor 4. The vertical slide rail 2 is provided with a through groove penetrating the upper and lower surfaces. When the tail water suction mechanism slides along the vertical slide rail 2, the suction pipe group of the tail water suction mechanism can extend into the breeding pond 29 from the through groove. The horizontal slide rail 1 and the vertical slide rail 2 both reserve extra lengths to ensure that, with the cooperation of the first linear motor 3 and the second linear motor 4, the tail water suction mechanism can move to any position above the breeding pond 29

[0052] In this embodiment, the suction pipe group includes: a suction pipe 5, the outer diameter of which is smaller than the width of the through groove, and one end of the suction pipe 5 extends into the breeding pond 29 from the through groove; a connecting pipe 6, the outer diameter of which is larger than the width of the through groove, and the connecting pipe 6 is respectively connected to the other end of the suction pipe 5 and the tail water purification system; a suction pump is arranged on the connecting pipe 6 for sucking the tail water in the breeding pond 29 into the tail water purification system through the suction pipe 5 and the connecting pipe 6.

[0053] In this embodiment, the connecting pipe 6 is made of a flexible material, which is convenient for the connecting pipe 6 to move together with the second linear motor 4. In some other embodiments, the part of the connecting pipe 6 located on the vertical slide rail 2 can be set as a rigid structure, and the rest of the connecting pipe 6 can be set as a flexible structure. In this way, both the strength of the connecting pipe 6 on the vertical slide rail 2 and the smoothness of the overall movement of the connecting pipe 6 with the second linear motor 4 can be ensured.

[0054] In some other embodiments, a limiting member for limiting the connecting pipe 6 can also be arranged on the vertical slide rail 2 to ensure that the connecting pipe 6 can only slide along the vertical slide rail 2 and will not fall into the breeding pond 29. The end of the vertical slide rail 2 can also be set as an arc angle to avoid abrasion caused during the movement of the connecting pipe 6 and the vertical slide rail 2.

[0055] In this embodiment, the tail water purification system includes: a primary filtration mechanism, which is communicated with the connecting pipe 6 and is used for filtering particulate matters in the tail water; a secondary filtration mechanism, which is communicated with the primary filtration mechanism and is used for filtering suspended matters in the tail water.

[0056] The primary filtration mechanism includes: a primary filtration cylinder 7, which has a first water inlet 8 and a first water outlet 9. The first water inlet 8 is located below the first water outlet 9. The first water inlet 8 is communicated with the connecting pipe 6, and the first water outlet 9 is communicated with the secondary filtration mechanism; a filter screen 10 is arranged in the primary filtration cylinder 7 and is located between the first water inlet 8 and the first water outlet 9.

[0057] The secondary filtration mechanism includes: a secondary filtration cylinder 11, which has a second water inlet 12 and a second water outlet 13. The second water inlet 12 is located below the second water outlet 13. The second water inlet 12 is communicated with the first water outlet 9; a filtering component is arranged in the secondary filtration cylinder 11 and is located between the second water inlet 12 and the second water outlet 13.

[0058] In this embodiment, the filtering component includes: a first mounting frame 14, a second mounting frame 16, and a filter bag 15 clamped between the first mounting frame 14 and the second mounting frame 16. Both the first mounting frame 14 and the second mounting frame 16 are fixedly connected to the inner side wall of the secondary filtration cylinder 11. A base 17 is arranged in the secondary filtration cylinder 11 and is close to the second water inlet 12. A first through hole is arranged through the upper and lower surfaces in the middle of the base 17; a support member 18 is fixedly arranged on the base 17. A second through hole is arranged through the upper and lower surfaces of the support member 18, and the second through hole is communicated with the first through hole; the lower edges of the first mounting frame 14, the second mounting frame 16, and the filter bag 15 are all fixedly connected to the support member 18, and the first mounting frame 14, the second mounting frame 16, and the filter bag 15 are all hemispherical structures bulging upward. The lower surface of the second mounting frame 16 corresponds to the second through hole. In this embodiment, the inner diameters of the first mounting frame 14, the filter bag 15, and the second mounting frame 16 decrease in sequence. The first mounting frame 14 is located above, and the second mounting frame 16 is located below. The first mounting frame 14, the filter bag 15, and the second mounting frame 16 are closely attached. The first mounting frame 14 and the second mounting frame 16 are hollowed out. The hollowed through holes should not be too large or too small. It is best that the inner diameter of the hollowed through hole is about twice the size of the mesh of the filter bag 15. If the hollowed through hole is too large, the impact force on the filter bag 15 will also increase, which is not conducive to ensuring the stability of the filter bag 15. If the hollowed through hole is too small, impurities may be intercepted at the hollowed part of the mounting frame, which is also not conducive to the backwashing efficiency.

[0059] In this embodiment, a first drain pipe 19 is provided at the bottom of the primary filter cartridge 7, and a second drain pipe 20 is provided at the bottom of the secondary filter cartridge 11. Both the first drain pipe 19 and the second drain pipe 20 are connected to the screw press 21. A first drain valve 22 is provided on the first drain pipe 19, and a second drain valve 23 is provided on the second drain pipe 20. The drain pipe 24 is connected to the first drain pipe 19. An inlet valve 26 is provided at the second water inlet 12. A drain valve 25 is provided on the drain pipe 24, and an outlet valve 27 is provided at the second water outlet 13. The flushing pipe 28 is connected to the secondary filter cartridge 11, and the connection point is above the filter assembly.

[0060] The specific working process is as follows:

[0061] 1. Aquaculture tail water treatment

[0062] Under the action of the first linear motor 3 and the second linear motor 4, the water suction pipe 5 moves to the area to be suctioned in the aquaculture pond 29 by a compound motion. The tail water in the aquaculture pond 29 is suctioned into the tail water purification system through the water suction pipe 5 and the connecting pipe 6 by using a water pump. During the suction process, the connecting pipe 6 is loaded on the longitudinal slide rail 2 and moved together by the second linear motor 4.

[0063] The tail water first enters the primary filter cartridge 7 from the connecting pipe 6. The tail water passes through the filter screen 10 from bottom to top, and large particle impurities are intercepted and naturally settle to the bottom of the primary filter cartridge 7.

[0064] After being filtered by the primary filter cartridge 7, the tail water enters the secondary filter cartridge 11, passes through the base 17 and the support member 18 from bottom to top in sequence, passes through the hollow through holes of the second mounting frame 16 and then passes through the filter bag 15. Small particle impurities such as suspended matter are intercepted and naturally settle to the bottom of the secondary filter cartridge 11. The filtered tail water passes through the hollow through holes of the first mounting frame 14 and finally discharges from the second water outlet 13 of the secondary filter cartridge 11, and can be recycled or harmlessly discharged.

[0065] 2. Sediment treatment

[0066] When a certain amount of sediment accumulates at the bottoms of the primary filter cartridge 7 and the secondary filter cartridge 11, the first drain valve 22 and the second drain valve 23 are opened, and the sediment is transported to the screw press 21 for compression treatment to reduce its volume and facilitate subsequent further treatment.

[0067] 3. Backwashing

[0068] When the secondary filter cartridge 11 has been continuously operating for a certain period of time, close the inlet valve 26, outlet valve 27 and the second sewage discharge valve 23 of the secondary filter cartridge 11, and open the drain valve 25. Deliver clean water flow to the secondary filter cartridge 11 through the flushing pipe 28. The water flow passes through the hollow through-holes of the first mounting frame 14 and flushes the filter bag 15 from the outside to the inside. The impurities adhered to the inner surface of the filter bag 15 are washed off and sink to the bottom of the secondary filter cartridge 11, and finally are discharged from the drain pipe 24.

[0069] It should be noted that the flushing pipe 28 is connected to the earphone filter cartridge and extends upward. Therefore, when filtering the tail water under normal conditions, there is no need to set a valve on the flushing pipe 28.

[0070] After statistics, the primary filter cartridge 7 and secondary filter cartridge 11 disclosed in this embodiment can effectively remove large particle impurities and small particle suspended matters in the tail water. The filter bag 15 has not shown any rupture after continuous use for 24 hours, and there has been no rupture during the continuous use for 7 days for treating the tail water of different aquaculture ponds 29.

[0071] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0072] The embodiments described above are only for describing the preferred mode of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention shall fall within the protection scope determined by the claims of the present invention.
