Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment in breeding farms, and in particular to a pig farm wastewater treatment device. Background Art

[0002] With the rapid development of pig farming, factory production has become the main trend in pig production. This trend has led to the continuous expansion of pig farming, and with it the generation of a large amount of pig farm wastewater. These wastewaters are mainly composed of urine, part or all of feces, feed residues and flushing water. The discharge volume has far exceeded the natural absorption capacity of the environment and has become a serious source of agricultural pollution. Therefore, pig farm wastewater needs to be treated.

[0003] In the existing pig wastewater treatment process, a significant technical bottleneck lies in the single treatment method and inefficiency. Specifically, the wastewater is first introduced into the treatment tank and only preliminarily filtered through a basic filter. Although this step can remove some coarse impurities, its filtering effect is inadequate when faced with the fine particles, tiny particles and floating objects widely present in the wastewater. This directly leads to the treated water still relying on additional secondary filtration methods to meet the emission standards, which not only greatly increases the treatment cost, but also significantly reduces the overall wastewater treatment efficiency. In addition, after treating the wastewater, the traditional method relies on manual cleaning of impurities on the filter net. This process is not only labor-intensive, time-consuming and labor-intensive, but also significantly increases labor costs. More importantly, the residence time of wastewater in the sedimentation tank is often difficult to control and depends on the operator's experience and judgment. This not only leads to unstable treatment effects, but also affects the efficiency and effectiveness of subsequent treatment steps due to insufficient or excessive sedimentation.

A first collection box 42 and a second collection box 43 are fixedly connected to one side of the top of the processing tank 1, the position of the first collection box 42 corresponds to the position of the first door panel 39, and the position of the second collection box 43 corresponds to the position of the second door panel 40. A trigger mechanism is installed on the outside of the processing tank 1, and the trigger mechanism is used to automatically open the first door panel 39 and the second door panel 40. A limit assembly is provided inside for automatically limiting the first filter plate 17 and the second filter plate 18 when feeding materials. The limit assembly includes a connecting tube 20 fixedly connected to one side of the slip ring 13, one end of the connecting tube 20 is slidably connected to a plug 21, one side of the outer tube 6 is fixedly connected to an alignment box 19, one side of the alignment box 19 is fixedly connected to a connecting box 25, a plug hole 22 is provided at the bottom of the connection between the connecting box 25 and the alignment box 19, the connecting tube 20 and the plug 21 are located inside the alignment box 19, and a return assembly is also installed inside the processing tank 1, and the return assembly is used to automatically return the first filter plate 17 and the second filter plate 18;

[0036] Through the filter assembly, the function of preliminarily filtering the impurities in the wastewater and transporting them upward to the first filter plate 17 for secondary filtration is achieved. This double filtration mechanism significantly improves the treatment effect of the wastewater and reduces the residual impurities. When in use, the coagulant is added from the inside of the addition tube 5 into the inside of the treatment tank 1. At this time, the coagulant coagulates the fine particles and floating objects in the wastewater into blocks and sinks to the bottom of the treatment tank 1. At this time, the impurities that have sunk to the bottom are input to the top of the first filter plate 17 and the second filter plate 18 through the spiral dragon rod 11, thereby promoting the removal of fine particles and floating objects in the wastewater, and also facilitating the automatic output of impurities in the later stage. This method not only reduces labor costs but also improves the filtration effect.

[0037] like Figures 1 to 9 As shown, the bottom of the processing tank 1 is in the shape of an inverted cone, the bottom of the outer tube 6 is fixedly connected to the accumulation tube 7, one side of the accumulation tube 7 is provided with an input hole 8, the bottom end of the spiral dragon rod 11 is fixedly connected to the turntable 9 through an axis, the bottom of the turntable 9 is rotatably connected to the bottom of the processing tank 1 through an axis, the diameter of the turntable 9 is adapted to the diameter of the bottom of the processing tank 1, one side of the turntable 9 is fixedly connected to a scraper 10, the side wall of the scraper 10 is fitted with the side wall of the bottom of the processing tank 1, the tops of the outer tube 6 and the inner tube 52 are fitted together, a discharge hole 12 is provided at the fitting place between the tops of the outer tube 6 and the inner tube 52, and the position of the first filter plate 17 in the initial state is located at the bottom of the discharge hole 12;

[0038] Through the spiral dragon rod 11, when treating wastewater, the pig farm wastewater is first input from the inside of the water pipe 4 to the inside of the treatment tank 1. At this time, the wastewater will be filtered through the first filter plate 17 and the second filter plate 18, thereby promoting coarse filtration of the wastewater. After that, a coagulant is added to the inside of the treatment tank 1 through the addition tube 5 to promote the fine particles and floating objects in the wastewater to condense into blocks and sink to the bottom of the treatment tank 1. At this time, by setting the shape of the treatment tank 1 to be an inverted cone, the condensate is concentrated to the middle of the bottom of the treatment tank 1 and gathered to the top of the turntable 9. At this time, by starting the motor 2, the spiral dragon rod 11 is caused to rotate. At the same time, since the turntable 9 is fixedly connected to the bottom end of the spiral dragon rod 11, the turntable 9 is in a rotating state. At this time, the condensate on the top of the turntable 9 will rotate, and when the rotation squeezes each other to the inside of the input hole 8, the spiral dragon rod 11 will rotate to promote the condensate to be transported to the top of the inner layer tube 52, and at the same time fall from the inside of the discharge hole 12 to the top of the first filter plate 17 and the second filter plate 18, so as to achieve the effect of secondary filtration of wastewater, and at the same time avoid the trouble of traditional manual cleaning of sediment, thereby improving work efficiency and the effect of wastewater filtration, and facilitating the automatic output of impurities in the later stage. At the same time, through the scraper 10, when the turntable 9 rotates, the scraper 10 will scrape the inside of the bottom of the treatment tank 1, so that the impurities sticking to the inner wall of the treatment tank 1 are scraped off, thereby facilitating the removal of impurities in the wastewater.

[0039] like Figures 3 to 6 As shown, the first filter plate 17 and the second filter plate 18 have an inclined shape, and the outside of the first filter plate 17 and the second filter plate 18 are in contact with the inside of the top of the treatment tank 1, and the size of the inner hole of the first filter plate 17 is larger than the size of the inner hole of the second filter plate 18;

[0040] By setting the first filter plate 17 and the second filter plate 18, the wastewater entering the treatment tank 1 at the beginning can be cross-filtered, and at the same time, the sediment at the bottom of the treatment tank 1 is input into the first filter plate 17 and the second filter plate 18 again through the spiral dragon rod 11 at a later time, which can promote the wastewater to undergo secondary filtration, and then promote all the impurities in the wastewater to accumulate on the first filter plate 17 and the second filter plate 18, which not only facilitates the filtration of the wastewater, but also facilitates the automatic output of impurities in the later period. At the same time, by setting the size of the holes of the first filter plate 17 and the second filter plate 18, the coarse particles in the wastewater can be accumulated on the top of the first filter plate 17, and the fine particles can be accumulated on the top of the second filter plate 18, thereby achieving the effect of treating coarse particles and fine particles in the wastewater.

[0042] By means of the output assembly and the trigger mechanism, the impurities remaining on the top of the first filter plate 17 and the second filter plate 18 can be automatically output from the interior of the processing tank 1. When in use, the sediment at the bottom is input to the top of the first filter plate 17 and the second filter plate 18 again through the spiral dragon rod 11. At this time, the first filter plate 17 and the second filter plate 18 will automatically drop by the principle of gravity, and at the same time, the first door plate 39 and the second door plate 40 will be automatically opened by pulling the trigger mechanism. At this time, when the first filter plate 17 and the second filter plate 18 move to one side of the first door plate 39 and the second door plate 40, the first filter plate 17 and the second filter plate 18 are set at an inclined angle, so that the impurities on the top of the first filter plate 17 and the second filter plate 18 are moved to the bottom of the processing tank 1. The first collecting box 42 and the second collecting box 43 are moved to the inside, and then output from the discharge box 44, so as to achieve the effect of automatically outputting impurities, while avoiding the trouble of traditional manual cleaning of impurities and improving work efficiency. At the same time, the automatic output of impurities replaces the traditional manual cleaning of impurities. The degree of wastewater treatment can be judged by observing the time when the impurities are discharged, thereby improving the treatment effect of the wastewater, thereby achieving the effect of controlling the discharge time of the wastewater after filtration. When the spiral dragon rod 11 inputs the sediment at the bottom of the processing tank 1 to the top of the first filter plate 17 and the second filter plate 18, the top of the first filter plate 17 and the second filter plate 18 will accumulate impurities. At this time, when the impurities accumulate to a certain amount, the first filter plate 1 7 and the second filter plate 18 will move downward with impurities, at this time the slip ring 13 will move downward outside the inner tube 52, and at the same time pull one end of the second pull rope 33 to move, at this time the other end of the second pull rope 33 will pull the U-shaped rod 34 to move, at this time the two ends of the U-shaped rod 34 will pull one end of the third pull rope 37 to move toward one end of the first slide cylinder 36, at this time the second slide cylinder 38 is set to be connected to the first collection box 42 and the second collection box 43 at an inclined angle, so that the other ends of the two third pull ropes 37 pull the bottom of the first door panel 39 and the second door panel 40 to move toward the inside of the first collection box 42 and the second collection box 43, thereby prompting the first door panel 39 and the second door panel 40 to be opened, at this time When the lowest end of the second filter plate 18 moves to correspond to the position of the second door panel 40, the position of the second filter plate 18 and the first filter plate 17 is fixed by the limiting assembly. At this time, the first filter plate 17 and the second filter plate 18 are set at an inclined angle, so that impurities on the top of the first filter plate 17 and the second filter plate 18 are input into the first collecting box 42 and the second collecting box 43 for collection. At the same time, by providing an inclined plate at the bottom of the first collecting box 42 and the second collecting box 43, the impurities collected in the first collecting box 42 and the second collecting box 43 automatically roll to the inside of the discharge box 44, and are automatically output from the inside of the discharge box 44, thereby avoiding the trouble of traditional manual cleaning of impurities.

[0043] like Figures 3 to 9 As shown, a third spring 32 is fixedly connected to the interior of the connecting tube 20, one end of the third spring 32 is fixedly connected to one end of the plug 21, and one end of the plug 21 away from the third spring 32 contacts the side wall inside the alignment box 19, and when the plug 21 abuts against the side wall inside the alignment box 19, the third spring 32 is in a tight state, and when one end of the plug 21 moves to the interior of the plug hole 22, the position of the second filter plate 18 corresponds to the position of the second door plate 40, and the position of the first filter plate 17 corresponds to the position of the first door plate 39;

[0044] The setting of the limit assembly ensures the accurate positioning of the first filter plate 17 and the second filter plate 18 during the feeding process, and prevents the leakage of impurities or the decrease of processing efficiency due to position deviation. At the same time, the matching use of the plug 21 and the socket 22 enables the first filter plate 17 and the second filter plate 18 to be accurately aligned with the corresponding collection box, ensuring that impurities can be smoothly discharged into the collection box. When the slip ring 13 moves downward with the first filter plate 17 and the second filter plate 18, the connecting tube 20 will slide inside the second slide groove 16 with the plug 21. At this time, when the position of the plug 21 moves to the position of the socket 22, When the positions are corresponding, the plug 21 will automatically rebound through the third spring 32, prompting one end of the plug 21 to be stuck into the interior of the plug hole 22 and contact the interior of the trapezoidal groove 24, thereby prompting the position of the slip ring 13 to be fixed, and the positions of the first filter plate 17 and the second filter plate 18 are fixed, thereby facilitating the complete discharge of impurities on the top of the first filter plate 17 and the second filter plate 18, thereby avoiding the problem of automatic return of the first filter plate 17 and the second filter plate 18 when the impurities on the top of the first filter plate 17 and the second filter plate 18 are not completely discharged, thereby ensuring that the impurities can be smoothly discharged into the collection box.

[0045] like Figures 1 to 9As shown, the return assembly includes a fixed block 27 fixedly connected to the bottom of the connection box 25, the bottom of the fixed block 27 is fixedly connected to the first spring 26, the bottom end of the first spring 26 is fixedly connected to the alignment block 23, one side of the alignment block 23 is provided with a trapezoidal groove 24, the position of the trapezoidal groove 24 corresponds to the position of the jack 22, one side of the outer tube 6 is provided with a second slide groove 16, the connecting tube 20 is slidably connected to the inside of the second slide groove 16, the top of the alignment block 23 is fixedly connected to the fourth pull rope 45, one side of the top of the processing tank 1 is rotatably connected to the fifth pulley 51, the top of the processing tank 1 is rotatably connected to the second pulley 47, and the fourth pull rope 45 is away from the alignment block 23. One end of the block 23 passes through the inside of the fifth pulley 51 and the second pulley 47 respectively and is fixedly connected to one side of the bottom of the outside of the treatment tank 1. When the wastewater inside the treatment tank 1 is full, it is located at the bottom of the connection box 25. The top of the treatment tank 1 is fixedly connected with a fixed cylinder 29, and the inside of the fixed cylinder 29 is slidably connected with a slider 30. The bottom of the slider 30 is fixedly connected with a second spring 31, and the bottom end of the second spring 31 is fixedly connected to the top of the treatment tank 1. The bottom of the slider 30 is fixedly connected with a first pull rope 28, and the end of the first pull rope 28 away from the slider 30 passes through the inside of the second spring 31 and the top of the treatment tank 1 and is fixedly connected to the top of the slip ring 13.

[0046] By using the return assembly and the trigger assembly in coordination, the automatic opening and closing of the first door panel 39 and the second door panel 40, as well as the automatic return of the first filter plate 17 and the second filter plate 18 are realized, ensuring the continuity and smoothness of the whole process. When the impurities on the top of the first filter plate 17 and the second filter plate 18 are completely output, the fourth pull rope 45 is pulled to connect one end of the outside of the processing tank 1, so that the other end of the fourth pull rope 45 pulls the alignment block 23 to move toward the bottom of the fixed block 27. At this time, one side of the bottom of the alignment block 23 will squeeze one end of the plug 21, so that one end of the plug 21 The second filter plate 17 and the second filter plate 18 are moved back to their original positions. At this time, the second pull rope 33 releases the tension on the first door panel 39 and the second door panel 40, causing the first door panel 39 and the second door panel 40 to automatically close through the torsion spring hinge 41, thereby avoiding the problem of wastewater flowing out of the first door panel 39 and the second door panel 40 when the next wastewater is input later. At the same time, by setting the wastewater in the treatment The water level line when the inside of the processing tank 1 is full can prevent the waste water from being too full and flowing out from the joint of the first door panel 39 and the second door panel 40, and from the second chute 16 and the first chute 15 into the inner part of the outer tube 6, thereby facilitating the treatment of the waste water. At the same time, by setting the trapezoidal groove 24 in a trapezoidal shape, it is not only convenient to limit the plug 21, but also when the limit of the plug 21 is released later, the plug 21 can be squeezed out of the inside of the plug hole 22 along the trapezoidal groove 24, thereby prompting the first filter plate 17 and the second filter plate 18 to achieve the effect of automatic return. At the same time, the second spring 31 is set to When the first filter plate 17 and the second filter plate 18 move downward, the slip ring 13 will drive one end of the first pull rope 28 to move downward. At this time, the other end of the first pull rope 28 will pull the slider 30 to slide toward the top of the processing tank 1, squeezing the second spring 31 at the same time. Then, the limit on the plug 21 is released through the return assembly. At this time, the second spring 31 will automatically rebound, prompting the slider 30 to pull one end of the first pull rope 28 to move upward, thereby prompting the slip ring 13 to automatically return to the original position with the first filter plate 17 and the second filter plate 18, thereby facilitating the automatic output of impurities in the later stage.
