Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to an aquaculture wastewater treatment device. Background Art

[0002] In the process of aquaculture, some feed and bait cannot be completely digested and absorbed by fish or other aquatic animals after ingestion, and are eventually discharged into the water in the form of feces and waste, resulting in the presence of organic matter, nitrates, phosphates, heavy metals and other pollutants in the aquaculture wastewater. Wastewater treatment is generally divided into three levels: primary treatment, which is the application of physical treatment methods to remove insoluble pollutants and parasite eggs in sewage; secondary treatment, which is the application of biological treatment methods to oxidize and degrade various complex organic matter in sewage into simple substances; tertiary treatment, which is the application of chemical precipitation, biochemical, physical and chemical methods, etc., to remove phosphorus, nitrogen, difficult-to-degrade organic matter, and inorganic salts in sewage.

[0003] A microbial treatment device for urban sewage treatment disclosed in the patent application with reference publication number CN113354099A comprises a box body, the upper end of which is connected to a box cover by a thread, the inside of which is fixedly sleeved with a bearing 1, the inside of which is fixedly sleeved with a stirring barrel, the outside of which is fixedly connected with two symmetrically distributed stirring frames, the inside of which is fixedly connected with a plurality of evenly distributed water outlet pipes, the water outlet pipes are provided with through holes, the inside of which is slidably connected with two symmetrically distributed telescopic rods, and the outsides of the two telescopic rods are both provided with springs. By adding structures such as a thermostat, a thermostat heater and a stirring plate to the device, the microbial solution can be preheated in advance, the activity of the microorganisms can be enhanced during the constant temperature heating process, and the solution can be stirred by the stirring plate so that it is heated evenly, thereby reducing the time for microorganisms to treat sewage and improving the sewage treatment efficiency.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 11 As shown, an aquaculture wastewater treatment device includes the following embodiments:

[0040] like Figures 1 to 8 As shown, embodiment 1 includes a treatment barrel 1, a support plate 101 is fixedly connected inside the treatment barrel 1, a liquid inlet pipe 9 for water inlet is fixedly connected to the top of the treatment barrel 1, a drainage pipe 10 for drainage is fixedly connected to the bottom of the treatment barrel 1, and a bracket is fixedly connected to the bottom of the treatment barrel 1, and also includes:

[0041] A processing frame 2 is arranged on the top of the support plate 101, a sealing member is arranged on the top of the processing frame 2, a reciprocating screw 3 is arranged inside the processing barrel 1, the reciprocating screw 3 rotates with the processing frame 2, the reciprocating screw 3 penetrates the processing frame 2 and passes through the support plate 101, a sliding groove is arranged on the outside of the reciprocating screw 3, the reciprocating screw 3 is connected to the processing frame 2 through a ball nut pair, a rotating cylinder 4 is arranged inside the processing frame 2, the rotating cylinder 4 is connected to the bottom of the processing frame 2, and is rotatably connected to the bottom end of the processing frame 2;

[0042] A plurality of stirring members are fixedly connected to the outside of the rotating drum 4, and the plurality of stirring members are arranged in a ring around the rotating drum 4, and the plurality of stirring members are connected to the rotating drum 4. A spray member is arranged inside the processing frame 2, and a transmission member is arranged between the spray member and the plurality of stirring members. When the plurality of stirring members rotate with the rotating drum 4, the transmission member drives the spray member to reverse and add liquid;

[0043] A connecting pipe 701 for discharging the mixed liquid is fixedly connected to the bottom of the processing frame 2 , and the connecting pipe 701 is connected to the bottom of the rotating cylinder 4 .

[0044] In specific implementation, when treating wastewater, it is often necessary to add bacterial agents to make the bacterial agents and wastewater produce biochemical reactions to separate and remove pollutants in the wastewater in a dissolved or colloidal state or convert them into harmless substances. The substances are allowed to settle by standing, thereby achieving the purification of the wastewater. In the process of adding bacterial agents to sewage, it often takes a long time for the bacterial agents to mix with the wastewater at the bottom, resulting in a long reaction time between the bacterial agents and the wastewater. Therefore, in this solution, the sewage is added to the top of the support plate 101 through the liquid inlet pipe 9. At this time, a drive motor is arranged on the top of the treatment barrel 1, and the output shaft of the drive motor is fixedly connected to the reciprocating screw rod 3. , the reciprocating screw 3 drives the treatment frame 2 to rise, and the sewage enters the treatment frame 2 through the sealing member on the top of the treatment frame 2, and then the rotating cylinder 4 inside the treatment frame 2 rotates along with the rotation of the reciprocating screw 3, so that the rotating cylinder 4 drives the stirring member to rotate inside the treatment frame 2, and the sewage inside the treatment frame 2 is stirred clockwise. At this time, the transmission member drives the spray member to rotate counterclockwise, and the spray member sprays the bacterial agent in the opposite direction into the wastewater rotating clockwise, which can effectively avoid the problem of vortex generated by unidirectional rotation, so that the bacterial agent and the wastewater are agitated, thereby intensifying the mixing treatment of the wastewater and the bacterial agent, and can improve the mixing effect;

[0045] After being treated, the sewage is transported to the inside of the rotating drum 4 through a plurality of stirring elements, which avoids too short a mixing time between the sewage and the bacterial agent, lengthens the mixing path of the bacterial agent and the sewage, further improves the mixing effect, and is discharged to the bottom of the support plate 101 through the rotating drum 4, thereby achieving improved sewage treatment efficiency.

[0046] like Figures 1 to 3 As shown, embodiment 2: the seal includes a second rotating ring 206 fixedly connected to the top of the processing frame 2, the second rotating ring 206 is rotatably connected to the first rotating ring 202 inside, the first rotating ring 202 is rotatably connected to the sealing disk 201 inside, and the top of the sealing disk 201 is provided with a liquid inlet groove 203 for liquid inlet.

[0047] The inner wall of the processing barrel 1 is provided with a plurality of limiting grooves 205 , and the outer side of the processing frame 2 is fixedly connected with limiting blocks 204 corresponding to the plurality of limiting grooves 205 . The limiting blocks 204 extend into the limiting grooves 205 and are slidably connected to the limiting grooves 205 .

[0048] In specific implementation, when the driving motor drives the reciprocating screw 3 to rotate, the reciprocating screw 3 is connected to the processing frame 2 through the ball nut pair, and through the limiting cooperation of the limiting block 204 and the limiting groove 205, the processing frame 2 drives the seal and the rotating cylinder 4 to rise together. When the processing frame 2 rises, the sewage on the top of the processing frame 2 is squeezed, and the sewage enters the interior of the processing frame 2 through the liquid inlet groove 203. As the processing frame 2 rises, the flow of the sewage is intensified.

[0049] like Figure 8 As shown, in this embodiment, a sliding block 401 is fixedly connected to the inner wall of the rotating cylinder 4, the sliding block 401 extends to the inside of a sliding groove opened on the outside of the reciprocating screw 3, and is slidably connected to the reciprocating screw 3, a liquid outlet groove 402 is opened at the bottom end of the rotating cylinder 4, and the rotating cylinder 4 is connected to the connecting pipe 701 through the liquid outlet groove 402.

[0050] During specific implementation, when the reciprocating screw 3 drives the processing frame 2 to rise, the rotating cylinder 4 is rotated and connected to the bottom end of the processing frame 2, pushing the rotating cylinder 4 to rise together. During the rotation of the reciprocating screw 3, since a sliding groove is provided on the outside of the reciprocating screw 3, the sliding block 401 fixedly connected to the inner wall of the rotating cylinder 4 extends to the sliding groove on the outside of the reciprocating screw 3. Therefore, when the reciprocating screw 3 rotates, it drives the rotating cylinder 4 to rotate together. At this time, multiple stirring members fixedly connected to the outside of the rotating cylinder 4 rotate together with the rotating cylinder 4 and rotate inside the processing frame 2 to mix the bacterial agent inside the processing frame 2, so that the sewage and the bacterial agent can be gradually mixed, avoiding the problem of uneven mixing caused by putting all the bacterial agents into the mixing, so that the bacterial agent and sewage are mixed more fully in this scheme.

[0051] like Figure 4 As shown, in this embodiment, the spray part includes a connecting frame 604 fixedly connected to the bottom of the first rotating ring 202, a plurality of spray heads 605 for spraying are fixedly connected to the inner side of the connecting frame 604, a plurality of stirring blades 606 are fixedly connected to the inner side of the connecting frame 604, and the outer sides of the plurality of stirring blades 606 are arranged in a ring around the rotating cylinder 4, a storage box 607 is fixedly connected to the top of the processing barrel 1, and a retractable tube is fixedly connected between the storage box 607 and the first rotating ring 202 for supplying liquid to the connecting frame 604.

[0052] The transmission member includes an outer gear ring 601 fixedly connected to one end of the stirring member, and a transmission gear 602 is rotatably connected to the bottom end of the processing frame 2. The transmission gear 602 is meshed with the outer gear ring 601, and the outer side of the transmission gear 602 is meshed with an inner gear ring 603, and the inner gear ring 603 is fixedly connected to the bottom of the connecting frame 604.

[0053] In specific implementation, when it is necessary to spray the bacterial agent, a water pump is arranged inside the storage box 607. The water pump conveys the bacterial agent to the connecting frame 604 fixedly connected at the bottom of the first rotating ring 202 through a telescopic tube, and sprays it through multiple injection heads 605 fixedly connected to the inner wall of the connecting frame 604. When multiple stirring members drive the outer gear ring 601 to rotate, the outer gear ring 601 drives the meshing transmission gear 602 to rotate, and the transmission gear 602 drives the outer meshing inner gear ring 603 to rotate in the opposite direction. The inner gear ring 603 is fixedly connected to the connecting frame 604, thereby driving the connecting frame 604 to spray in the opposite direction. During the spraying process, the multiple stirring blades 606 fixedly connected to the inner wall of the connecting frame 604 come into contact with the clockwise rotating water flow, thereby agitating the sewage and improving the mixing effect of the bacterial agent and the sewage.

[0054] like Figure 7 As shown, embodiment three: the stirring member includes a second connecting cylinder 502 fixedly connected to the rotating cylinder 4, one end of the second connecting cylinder 502 is rotatably connected to a bevel gear 506, the inner side of the bevel gear 506 is connected to the first connecting cylinder 501, the first connecting cylinder 501 is fixedly connected to the outer gear ring 601, a conveying auger 503 is arranged inside the first connecting cylinder 501, the conveying auger 503 and the bevel gear 506 are fixedly connected by a support rod, the bottom end of the processing frame 2 is fixedly connected to the second connecting cylinder 502, and the second connecting cylinder 502 is meshingly connected to a plurality of bevel gears 506.

[0055] In specific implementation, when multiple stirring members rotate with the rotating cylinder 4, the opening of the first connecting cylinder 501 at one end of the mixed liquid of sewage and bacterial agent enters the interior of the first connecting cylinder 501, and a conveying auger 503 is arranged between the first connecting cylinder 501 and the second connecting cylinder 502. The conveying auger 503 is fixedly connected to the bevel gear 506 through a support rod. When the rotating cylinder 4 rotates, the bevel gear 506 is meshed and connected with the bevel gear plate 505. Then, when the first connecting cylinder 501 and the second connecting cylinder 502 rotate with the rotating cylinder 4, the conveying auger 503 inside them rotates, and the mixed liquid is quickly conveyed to the interior of the rotating cylinder 4 through the conveying auger 503 at one end of the first connecting cylinder 501. During the conveying process of the conveying auger 503, the mixing effect is further achieved, and the mixed liquid is discharged through the liquid outlet groove 402 opened at the bottom of the rotating cylinder 4. The opening size of the liquid outlet groove 402 can be opened according to actual needs.

[0056] like Figures 9 to 11 As shown, in the fourth embodiment, a filter cartridge 703 is fixedly connected to the bottom of the support plate 101 , and the filter cartridge 703 is sleeved on the outside of the connecting pipe 701 . A flow groove 702 for drainage is provided on the outside of the bottom end of the connecting pipe 701 .

[0057] A rotating ring 801 is rotatably connected to the bottom of the connecting tube 701, and the rotating ring 801 is sleeved on the outside of the reciprocating screw 3. A connecting block 800 is fixedly connected to the inner wall of the rotating ring 801. The connecting block 800 extends to the inside of the slide groove opened on the outside of the reciprocating screw 3. A plurality of cleaning blades 802 are fixedly connected to the outside of the rotating ring 801, and the plurality of cleaning blades 802 are in contact with the inner wall of the filter cartridge 703.

[0058] In specific implementation, when the mixed liquid is discharged into the connecting pipe 701 through the processing frame 2, it is discharged through the flow groove 702 opened at the bottom of the connecting pipe 701, and filtered through the filter cartridge 703. The connecting pipe 701 rises as the processing frame 2 rises, and the flow groove 702 continuously discharges water at different heights of the filter cartridge 703, and is filtered through different positions of the filter cartridge 703, thereby ensuring the filtering effect of the filter cartridge 703, filtering the suspended matter in the sewage, and discharging the mixture of the bacterial agent and the sewage, so that the bacterial agent is continuously treated in the sewage.

[0059] like Fig.11 As shown, in this embodiment, a first magnetic ring 803 is fixedly connected to the bottom of a plurality of cleaning blades 802, a second magnetic ring 805 is sleeved on the outer side of the filter cartridge 703, the second magnetic ring 805 is magnetically attracted to the first magnetic ring 803, a fixed ring 806 is rotatably connected to the outer side of the second magnetic ring 805, and a retractable and foldable sealing sleeve 807 is fixedly connected between the fixed ring 806 and the bottom end of the interior of the processing barrel 1.

[0060] In specific implementation, the filter holes on the outside of the filter cartridge 703 will be blocked after filtering. Therefore, in this solution, by rotating the rotating ring 801 at the bottom of the connecting tube 701, the connecting tube 701 is driven to rise together with the rotating ring 801, and the cleaning blade 802 fixedly connected to the outside of the rotating ring 801 contacts the inside of the filter cartridge 703. When the reciprocating screw rod 3 rotates, the rotating ring 801 is driven to rise and rotate through the connecting block 800, and the cleaning blade 802 cleans the filter holes of the filter cartridge 703, and in order to ensure that the filtered liquid does not flow into the filter cartridge 70 through the filtration, the filter holes of the filter cartridge 703 are cleaned. 3, a second magnetic ring 805 is sleeved on the outside of the filter cartridge 703, and the second magnetic ring 805 is fixedly connected to the bottom of the cleaning blade 802 by magnetic adsorption of the first magnetic ring 803. When the first magnetic ring 803 rises, it drives the second magnetic ring 805 to rise together, and pulls the sealing sleeve 807 to extend through the fixing ring 806 to cover the filter cartridge 703, so as to prevent the filtered water from being discharged through the filtering holes at the bottom of the filter cartridge 703. The filtered water is discharged through the drain pipe 10 installed at the bottom of the processing barrel 1, so as to ensure the filtering effect of the filter cartridge 703 and achieve automatic cleaning.
