Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a high-efficiency treatment device for pig breeding sewage. Background Art

[0002] During the pig farming process, a large amount of breeding wastewater is produced. The breeding wastewater contains a large number of pollutants, such as heavy metals, residual antibiotics and a large number of pathogenic microorganisms. Therefore, if it is discharged directly or returned to the fields without treatment, it will lead to problems such as eutrophication of water bodies, soil pollution, groundwater pollution and bacterial resistance, which will cause serious pollution to the local ecological environment and farmland, and threaten human health.

[0003] Solid-liquid separation is a critical step in the aquaculture wastewater treatment process. This prevents larger solid impurities and residues from entering subsequent treatment stages, thereby reducing the risk of equipment clogging and damage and ensuring stable operation of the entire treatment process. However, existing aquaculture wastewater treatment equipment is prone to clogging after long-term operation due to the continuous load of impurity interception on the filter screen. When clogging reaches a certain level, the system must be shut down for filter cleaning and maintenance, which not only reduces filtration efficiency but also causes equipment interruptions, affecting the continuity of the overall treatment process.

In the description of the present invention, "plurality" means more than two, unless otherwise specifically defined.

[0022] like Figures 1-8 As shown, the present invention provides a highly efficient swine wastewater treatment device for coarse filtration of swine wastewater. The device comprises a housing 10 and a control box. A feed inlet 11 is formed at the top of the housing 10 and communicates with the interior thereof. A filtering mechanism is disposed within the housing 10. The filtering mechanism comprises a fixed cylinder 20, a rotating cylinder 30, a drive assembly 40, and a drain pipe 50.

[0023] The fixed barrel 20 is arranged horizontally, with an annular guide rail 26 fixedly mounted at each end. A front cover 21 and a rear cover 22 are fixedly mounted at each end of the fixed barrel 20. Both the front cover 21 and the rear cover 22 are fixedly connected to the chassis 10 via connecting posts 23. A first notch 24 is defined on the outer circumference of the fixed barrel 20, communicating with the interior thereof. The first notch 24 is located at the top of the fixed barrel 20 and is aligned with the feed port 11.

[0024] The rotating drum 30 is sleeved onto the outside of the fixed drum 20. An annular guide groove 34 is defined on the inner wall of the rotating drum 30. The inner wall of the annular guide groove 34 is in sliding contact with the annular guide rail 26. The rotating drum 30 is rotatable on the fixed drum 20, with the axis of the rotating drum 30 being collinear with the axis of the fixed drum 20. A plurality of filter holes 31 are defined on the outer circumference of the rotating drum 30, communicating with the interior thereof. An annular baffle 32 is fixedly mounted on the front and rear sides of the rotating drum 30. A plurality of partition plates 33 are disposed between the two annular baffles 32. The multiple partition plates 33 are arranged at equal intervals along the circumference of the rotating drum 30 and are fixedly connected to both the rotating drum 30 and the annular baffles 32. A filter tank 60 is formed between the two annular baffles 32 and the adjacent two partition plates 33.

[0025] The driving assembly 40 is used to control the rotation of the rotating drum 30; The drain pipe 50 is fixedly mounted on the front end cover 21 and communicates with the interior of the fixed cylinder 20. Preferably, the drain pipe 50 is located at the lower portion of the front end cover 21.

[0026] In the initial state, the notch of the uppermost filter tank 60 is aligned with the feed port 11 .

[0027] The specific working process of this equipment is: Operators use feeding equipment or suction equipment to deliver pig farming wastewater to the feed port 11. The pig farming wastewater falls through the feed port 11 into the uppermost filter tank 60 for filtration. Under the action of the filter holes 31, the filtered wastewater passes through the first gap 24 into the fixed cylinder 20 and is discharged through the drain pipe 50. The filtered residue remains in the filter tank 60.

[0028] After a period of time, the drive assembly 40 starts and controls the rotating drum 30 to rotate a certain angle until the slot of the next filter tank 60 is aligned with the feed port 11 to continue the filtering operation; and the filter tank 60 containing the residue rotates synchronously, and eventually under the action of gravity, the residue inside it will fall to the bottom of the chassis 10, making it convenient for the operators to collect it centrally.

[0029] In this device, the drive assembly 40 causes the notches of the various filter tanks 60 to align with the feed port 11 in turn, thereby performing the filtering operation. This allows the device to operate continuously without requiring downtime, thereby improving the filtration efficiency of pig farm wastewater. The filtered wastewater is ultimately discharged from the drain pipe 50, and the filtered residue falls to the bottom of the housing 10.

[0030] In one embodiment, the drive assembly 40 includes a ring gear 41 , a motor 42 , and a gear 43 .

[0031] The ring gear 41 is fixedly mounted on the outer circumference of the rotating drum 30. The motor 42 is fixedly mounted on the chassis 10 and electrically connected to the control box. The gear 43 is fixedly mounted on the output shaft of the motor 42 and meshes with the ring gear 41.

[0032] When the driving assembly 40 is working, the control box controls the motor 42 to start, and the output shaft of the motor 42 drives the gear 43 to rotate. Since the gear 43 is meshed with the ring gear 41, the ring gear 41 drives the rotating drum 30 to rotate.

[0033] The motor 42 is preferably a servo motor 42 having a timing module therein. After a timing program is input, the motor 42 starts at a fixed time, thereby controlling the rotating drum 30 to rotate by the same angle each time under the action of the gear 43 and the ring gear 41, thereby aligning the notch of the next filter tank 60 with the feed port 11.

[0034] In one embodiment, second notches 25 communicating with the interior of the fixing tube 20 are respectively formed on the outer circumference of the fixing tube 20 . The second notches 25 are located on the side of the fixing tube 20 .

[0035] The filter mechanism also includes a cleaning assembly 70, which includes a rotating shaft 71. The rotating shaft 71 is disposed transversely within the fixed cylinder 20, with its ends rotatably connected to the front cover 21 and the rear cover 22, respectively. A plurality of insertion rods 72 are fixedly mounted on the outer circumference of the rotating shaft 71. The insertion rods 72 pass through the second notches 25 and engage with the filter holes 31.

[0036] During operation, most of the hog wastewater residue falls to the bottom of the housing 10, but a small amount still clogs the filter holes 31. In the design of this device, since the insertion rods 72 are engaged with the filter holes 31, when the rotating drum 30 rotates, the rotating shaft 71 and the insertion rods 72 also rotate synchronously, and the insertion rods 72 are inserted into each filter hole 31 in turn, thereby clearing the clogged filter holes 31.

[0037] The design of the cleaning assembly 70 does not use any additional power source. It relies on the meshing action of the plug rod 72 and the filter hole 31, so that when the rotating cylinder 30 rotates, it can drive the rotating shaft 71 and the plug rod 72 to rotate synchronously, thereby automatically clearing and cleaning all the filter holes 31, further improving the filtration efficiency and filtration effect.

[0038] It is worth noting that, under the action of gravity, after the filtered sewage passes through the first gap 24 and enters the fixed cylinder 20, most of it will fall directly into the lower part of the fixed cylinder 20, and only a very small part will flow along the inner wall of the fixed cylinder 20 into the second gap 25. Therefore, the design of the second gap 25 will not cause the sewage in the fixed cylinder to be lost.

[0039] In one embodiment, the second notch 25 is located on the upper side of the fixed barrel 20. This design allows the insertion rod 72 to quickly clear the clogged filter holes 31. Otherwise, if the second notch 25 is located on the lower side of the fixed barrel 20, when cleaning the filter holes 31, the residue removed is likely to come into contact with the sewage in the fixed barrel 20 again and enter the sewage again.

[0040] In one embodiment, a discharging channel 12 is formed at the bottom of the chassis 10 and extends transversely therethrough. A belt conveyor 80 is provided at the discharging channel 12, the feeding end of the belt conveyor 80 being located directly below the filter assembly, and the discharging end of the belt conveyor 80 extending to the next process.

[0041] When the device is working, the belt conveyor 80 is always in the starting state.

[0042] When the drive assembly 40 controls the rotation of the rotating drum 30, the residue inside the filter tank 60 will fall onto the conveyor belt of the belt conveyor 80 due to gravity, and then be automatically transported to the next process for processing. This design further improves the automation level of the equipment and reduces manual intervention.

[0043] In one embodiment, a material guide frame 13 is provided at the feed port 11 , and the inner diameter of the material guide frame 13 gradually increases from low to high. The material guide frame 13 allows the material to have a tendency to enter the feed port 11 .

[0044] The design of the guide frame 13 plays a role in collecting and guiding the pig farming wastewater transported by the feeding equipment or the suction equipment, so that the pig farming wastewater can better enter the filter tank 60 through the feed port 11 to avoid spillage.

[0045] In one embodiment, the first end of the drain pipe 50 is connected to the interior of the fixed cylinder 20, and the second end of the drain pipe 50 extends outward after passing through the chassis 10. The staff can install a pipeline on the second end of the drain pipe 50 to transfer the filtered sewage to the next process for treatment.

[0046] In one embodiment, first limiting grooves 241 are formed on both sidewalls of the first notch 24, and a flow guide assembly 90 is disposed below and inside the first limiting grooves 241. A plurality of second limiting grooves 35 are formed circumferentially on the inner wall of the rotating drum 30. During the rotation of the rotating drum 30, when one of the filter tanks 60 aligns with the first notch 24, one of the second limiting grooves 35 moves above the first limiting groove 241 and communicates with the first limiting groove 241.

[0047] The deflector assembly 90 includes a rotating column 91, a first deflector plate 92, a second deflector plate 93, and a torsion spring (not shown in the drawings). The axis of the rotating column 91 is collinear with the axis of the fixed cylinder 20, and the two ends of the rotating column 91 are rotatably connected to the front cover 21 and the rear cover 22, respectively. The first deflector plate 91 is disposed in the first limiting groove 241 and is fixedly connected to the rotating column 91. The second deflector plate 93 is located directly below the first notch 24 and is fixedly connected to the rotating column 91. The torsion spring is mounted on the rotating column 91, with the first end of the torsion spring fixedly connected to the rotating column 91 and the second end of the torsion spring fixedly connected to the front cover 21 or the rear cover 22. The torsion spring causes the first deflector plate 91 to tend to approach the first limiting groove 241.

[0048] In the initial state, due to the action of the torsion spring, the end of the first guide plate 91 is located in the first limiting groove 241 , and thus does not affect the normal rotation of the rotating drum 30 .

[0049] When the driving assembly 40 is started and controls the rotating drum 30 to rotate a certain angle, when the next filter tank 60 is aligned with the first notch 24, a second limiting groove 35 will move above the corresponding first limiting groove 241, and at this time the second limiting groove 241 is connected to the first limiting groove 35.

[0050] In this way, during the filtering operation, the filtered sewage passes through the first notch 24 and enters the fixed cylinder 20, where it will hit the second guide plate 93. Under the action of the rotating column 91, the end of the first guide plate 92 will swing upward into the second limiting groove 35, thereby blocking the gap between the fixed cylinder 20 and the rotating cylinder 30, so as to prevent fine impurities in the sewage from entering between the fixed cylinder 20 and the rotating cylinder 30 and causing blockage and wear between the two, thereby ensuring that the rotating cylinder 30 can rotate smoothly.

[0051] When the filter tank 60 completes the filtering operation, under the action of the torsion spring, the end of the first guide plate 92 will return to the first limiting groove 241. At this time, the driving component 40 starts and controls the rotating drum 30 to rotate a certain angle until the next filter tank 60 is aligned with the first notch 24, and the filtering operation continues.

[0052] It is worth noting that the force of the torsion spring should be relatively small, and only needs to be able to make the end of the first guide plate 92 return to the first limiting groove 241 when there is no external force.

[0053] This structural design is very clever. It does not hinder the normal rotation of the rotating drum 30, and can also enable the first guide plate 92 to block the gap between the fixed drum 20 and the rotating drum 30 during the filtering operation, so as to prevent fine impurities in the sewage from entering between the fixed drum 20 and the rotating drum 30 and causing blockage and wear between the two.

[0054] In one embodiment, a sealing gasket 94 is fixedly mounted on the inner wall of the second limiting groove 35. When the end of the first guide plate 92 swings upward into the second limiting groove 35, the sealing between the first guide plate 92 and the second limiting groove 35 is improved, further preventing fine impurities in the sewage from entering between the fixed drum 20 and the rotating drum 30 and causing blockage and wear therebetween.

[0055] In one embodiment, the angle between the first guide plate 92 and the second guide plate 93 is an obtuse angle, so that the filtered sewage can better impact the second guide plate 93 after passing through the first gap 24 and entering the fixed cylinder 20 .

[0056] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as illustrative and non-restrictive in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description, and all changes that come within the meaning and range of equivalents of the claims are intended to be included therein.

[0057] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
