Abstract

This invention relates to the field of wastewater treatment technology and discloses a wastewater treatment device for animal husbandry. The device includes a wastewater tank and a centrally located waste collection cylinder. A rotating mechanism is installed inside the wastewater tank, driving a movable rod to revolve around the tank wall. A contact rod on the movable rod slides along a wavy groove on the tank wall and engages with a tension spring, causing a scraper to reciprocate up and down, scraping away dirt from the inner wall. Simultaneously, the movable rod moves a ring and a rotating sleeve, causing a spiral collection plate between them to rotate, scraping surface floating matter into the waste collection cylinder. Above the waste collection cylinder are a guide scraper limited by a hexagonal shaft and a vibrating sleeve. The rotating sleeve's bottom protrusion alternately presses down on a push rod and is reset by a spring, generating continuous up-and-down vibration to guide viscous solid waste downwards and prevent blockage. An overflow hole and a collection trough are located on the upper periphery of the wastewater tank to overflow and discharge the rising middle and lower layers of wastewater. This invention achieves mechanical linkage between solid waste collection, tank wall cleaning, anti-blockage discharge, and water separation.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for animal husbandry. Background Technology

[0002] With the development of large-scale and intensive livestock and poultry farming, farms discharge a large amount of livestock wastewater during daily operations. This wastewater usually contains a large amount of animal feces, undigested feed residue, bedding, and shed hair, among other suspended solids. Animal husbandry wastewater treatment equipment is a specialized environmental protection machine designed for solid-liquid separation and preliminary purification of this type of high-concentration organic wastewater. Its main function is to remove as much solid waste as possible from the water before it enters the subsequent deep biochemical treatment stage, thereby reducing the operating load of the entire wastewater treatment system.

[0003] In existing primary treatment processes for aquaculture wastewater, large primary sedimentation tanks or collection tanks are typically built to temporarily store the discharged aquaculture wastewater. In actual operation, the aquaculture wastewater is pumped into the treatment tank for settling. Under the influence of gravity, heavier solid impurities such as mud and sand gradually settle to the bottom of the tank, while a large amount of lighter mixtures such as manure, feed husks, and hair float and accumulate on the surface of the wastewater. To clean these floating objects, processing personnel usually install a linearly moving scraper on the top of the tank to scrape and push the scum on the surface of the liquid in one direction, or rely on manual labor to periodically scoop the scum at the edge of the tank using tools such as long-handled nets. The collected solid waste is then transferred to a dedicated composting area for further processing.

[0004] The drawback of existing technology is that, for aquaculture wastewater stored in large wastewater ponds, the solid floating matter and manure on the surface often exhibit an irregular, large-area dispersed floating state. Conventional one-way linear scraping equipment or manual dredging methods can usually only push the floating matter to one side edge of the pond, and cannot apply a continuous and effective centripetal force to the floating matter on the entire wide liquid surface. This cleaning method makes it difficult to quickly and automatically collect suspended solids in different areas of the wastewater pond. If the large-area dispersed manure is not thoroughly dredged for a long time, it is easy to crust and ferment on the water surface, which seriously affects the cleaning efficiency and centralized collection effect of the upper layer of suspended solids in aquaculture wastewater. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a wastewater treatment device for animal breeding, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a wastewater treatment device for animal breeding, comprising a wastewater tank with an open top for storing breeding wastewater, wherein multiple support legs are fixedly connected to the bottom of the outer wall of the wastewater tank for supporting the wastewater tank, and further comprising: The scraping mechanism, located inside the wastewater tank, scrapes away floating debris; A rotating mechanism, located inside the wastewater tank, drives the scraping mechanism to rotate and scrape away floating debris; The waste collection cylinder is fixedly connected to the middle of the inner wall of the wastewater tank and extends through the wastewater tank to its bottom to collect the floating debris after scraping. The scraping mechanism includes: A rotating sleeve is located on the top of the outer wall of the waste cylinder. A circular ring is installed on the inner wall of the wastewater tank, and its height is the same as that of the rotating sleeve. The spiral collecting plate is fixedly connected to the outer wall of the rotating sleeve and the inner wall of the ring, and scrapes away floating objects as the rotating sleeve rotates.

[0007] Preferably, the rotating mechanism includes: A circular track is fixedly connected to the upper outer wall of the wastewater tank; A circular swivel ring is rotatably connected to the outer wall of the ring track, and a T-shaped rod is fixedly connected to the top of the circular swivel ring; The sliding sleeve is slidably connected to the outer wall of the T-shaped rod, and a movable rod is fixedly connected to the bottom of the sliding sleeve. The outer wall of the movable rod is attached to the outer wall of the wastewater tank and extends downward through the ring to push the ring to rotate. The scraper is fixedly connected to the outer wall of the movable rod. As it rotates with the movable rod, it scrapes the inner wall of the wastewater tank.

[0008] Preferably, the rotating mechanism further includes: A tension spring is fitted onto the outer wall of the T-shaped rod, with its two ends connected to the bottom of the sliding sleeve and the top of the circular swivel, respectively, to pull the sliding sleeve downwards. A toothed ring is fixedly fitted onto the outer wall of a circular rotating ring and is used to drive the circular rotating ring to rotate.

[0009] Preferably, the inner wall of the wastewater tank is provided with a corrugated groove, and an abutment rod is fixedly connected to the inner wall of the movable rod. The abutment rod is attached to the corrugated groove, and when the abutment rod is attached to the crest of the corrugated groove, it pushes the abutment rod to move upward.

[0010] Preferably, the inner wall of the wastewater tank is provided with multiple overflow holes for overflowing wastewater in the wastewater tank; The outer wall of the wastewater tank is fixedly connected to a water collection trough for collecting overflow wastewater. The inner wall of the water collection trough is fixedly connected to two inclined water collection plates for concentrating and collecting overflow wastewater. The outer wall of the wastewater tank is fixedly connected to a water pipe for discharging wastewater from the water collection trough.

[0011] Preferably, the spiral collecting plate is provided with a guiding mechanism for guiding the solid waste on the spiral collecting plate into the waste cylinder when the spiral collecting plate rotates. The guiding mechanism includes: A fixing rod is installed at the center of the inner wall of the waste cylinder and is connected to the inner wall of the waste cylinder by multiple connecting rods; The movable sleeve is fitted onto the outer wall of the fixed rod, and a guide scraper is fixedly fitted above the outer wall of the movable sleeve. The guide scraper is positioned above the spiral collection plate and is used to guide the solid waste on the spiral collection plate into the waste cylinder.

[0012] Preferably, the waste hopper is equipped with a shaking mechanism inside for shaking the movable sleeve to promote the flow of solid waste. The shaking mechanism includes: A hexagonal shaft is fixedly connected to the top of the inner wall of the movable sleeve, and the hexagonal shaft is movably connected to the hexagonal groove opened at the top of the fixed rod to restrict the rotation of the movable sleeve; A spring, positioned within a hexagonal groove, pushes the hexagonal axis upwards, thereby causing the guide scraper to move upwards.

[0013] Preferably, the inner wall of the waste cylinder is provided with a shaking sleeve, and is connected to the outer wall of the movable sleeve through multiple synchronizing rods so as to move upward with the movable sleeve; Multiple protrusions are circumferentially and equidistantly fixedly connected to the bottom of the rotating sleeve and located on the inner wall of the waste cylinder. A push rod is fixedly connected to the outer wall of the movable sleeve, and the outer wall of the push rod is attached to the outer wall of the protrusion for pushing the push rod downward. The vibrating sleeve and the movable sleeve are tapered to facilitate the downward sliding of solid waste.

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This animal husbandry wastewater treatment equipment automatically cleans and collects the upper layer of suspended solids in animal husbandry wastewater by setting up a rotating mechanism inside the wastewater tank, driven by an external motor and a gear ring. The rotating mechanism drives the moving rod to revolve, which in turn causes the ring and the rotating sleeve to rotate synchronously. The spiral collection plate connected between the ring and the rotating sleeve generates a centripetal thrust, which allows the solid floating objects and fecal residue on the surface of the wastewater to be continuously scraped from the edge of the wastewater tank towards the center area and finally concentrated and pushed into the waste cylinder in the center.

[0015] 2. This wastewater treatment equipment for animal husbandry utilizes a corrugated groove on the inner wall of the wastewater tank. A contact rod is fixed inside the rotating rod that drives the circular ring. A tension spring fitted onto the outer T-shaped rod applies downward force, causing the contact rod to slide along the corrugated groove's trajectory as the rotating rod revolves around the circular ring. This creates alternating up-and-down motions, which in turn cause the scraper on the outer wall of the rotating rod to slide up and down simultaneously. This effectively removes and cleans the sticky dirt adhering to the inner wall of the wastewater tank, preventing long-term accumulation and crusting of the dirt.

[0016] 3. This wastewater treatment equipment for animal husbandry uses a movable sleeve and guide scraper inside the waste cylinder, which are limited by a hexagonal shaft. Multiple protrusions distributed circumferentially at the bottom of the rotating sleeve alternately press down on the push rod connected to the movable sleeve during rotation. When the pressure is lost, the spring at the bottom releases the elastic force instantly, causing the guide scraper and the internal vibrating sleeve to generate continuous up-and-down vibration. This breaks the adhesion between the viscous solid waste and the metal surface, thus guiding the solid waste to slide down the conical inner wall quickly and be discharged, preventing viscous materials from sticking to the wall or causing blockage.

[0017] 4. This wastewater treatment equipment for animal husbandry, by opening multiple overflow holes on the outer wall of the upper part of the wastewater tank and fixing an annular water collection tank to the outside of the overflow holes, along with a water collection plate symmetrically and inclinedly arranged at the bottom of the water collection tank and a discharge pipe connected to the lowest point of the water collection plate, enables the wastewater to pass through the overflow holes into the water collection tank when the upper floating matter is stripped off and the water level of the relatively clear wastewater in the middle and lower layers rises to the height of the overflow holes. The wastewater then flows through the overflow holes into the water collection tank and flows along the inclined water collection plate to the bottom water pipe for discharge, achieving effective separation and centralized discharge of solid waste and water.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] Please see Figure 1-8 This invention provides a wastewater treatment device for animal husbandry, including a wastewater tank 1 with an open top, which is used to centrally store the animal husbandry wastewater to be treated. Support legs 2 are uniformly fixedly connected to the bottom of the outer wall of the wastewater tank 1, which is used to stably support the wastewater tank 1. A waste material cylinder 5 is fixedly connected to the center of the inner wall of the wastewater tank 1, which extends vertically through the bottom wall of the wastewater tank 1 and downwards. The waste material cylinder 5 collects and discharges the separated solid floating matter. The wastewater tank 1 is equipped with a scraping mechanism 3 and a rotating mechanism 4 that drives the scraping mechanism 3 to operate.

[0022] The scraping mechanism 3 includes a rotating sleeve 31, which is rotatably mounted on the top area of ​​the outer wall of the waste cylinder 5. The inner wall of the wastewater tank 1 is provided with a ring 33, which is at the same horizontal height as the rotating sleeve 31. A spiral collecting plate 32 is fixedly connected between the outer wall of the rotating sleeve 31 and the inner wall of the ring 33. The spiral collecting plate 32 rotates in the same direction as the rotating sleeve 31. The inner discharge end of the spiral collecting plate 32 extends to the top opening of the waste cylinder 5 so that solid waste can fall into the waste cylinder 5.

[0023] The rotating mechanism 4 includes an annular rail 41 fixedly connected to the upper part of the outer wall of the wastewater tank 1. A circular rotating ring 42 is rotatably connected to the outer wall of the annular rail 41 via ball bearings. A gear ring 43 is fixedly sleeved on the outer wall of the circular rotating ring 42. A motor is fixedly installed above the outer wall of the wastewater tank 1. A gear is installed at the output end of the motor. The gear meshes with the gear ring 43, driving the circular rotating ring 42 to rotate around the wastewater tank 1. A T-shaped rod 44 is fixedly connected vertically upward to the top of the circular rotating ring 42. A sliding sleeve 45 is vertically slidably connected to the outside of the T-shaped rod 44. A movable rod 47 is fixedly connected to the bottom of the sliding sleeve 45. The outer wall of the movable rod 47 is attached to the inner wall of the wastewater tank 1. A through hole is opened on the surface of the circular ring 43, allowing the movable rod 47 to move downward through... The through hole extends downwards, and the movable rod 47 moves the inner wall of the through hole, causing the ring 33 to rotate synchronously. The movable rod 47 can slide up and down in the through hole in the vertical direction. The outer wall of the T-shaped rod 44 is fitted with a tension spring 46. The two ends of the tension spring 46 are connected to the bottom of the sliding sleeve 45 and the top of the circular rotating ring 42, respectively. The tension spring 46 is in a stretched state. The tension of the tension spring 46 is used to pull the sliding sleeve 45 and the movable rod 47 downwards. The outer wall of the movable rod 47 is fixedly connected with a scraper 410. The side of the scraper 410 is attached to the inner wall of the wastewater tank 1. The inner wall of the wastewater tank 1 is provided with a wavy groove 49. The inner side wall of the movable rod 47 is fixedly connected with an abutment rod 48. The end of the abutment rod 48 is inserted into and attached to the wavy groove 49.

[0024] Working principle: An external motor drives the gear ring 43 to rotate, which in turn drives the circular rotating ring 42 and the T-shaped rod 44 to rotate around the wastewater tank 1. The T-shaped rod 44 drives the movable rod 47 to revolve around the center of the wastewater tank 1 through the sliding sleeve 45. When the movable rod 47 revolves, it causes the circular ring 33 to rotate synchronously, which in turn drives the spiral collection plate 32 and the rotating sleeve 31 to rotate. The rotating spiral collection plate 32 generates a centripetal thrust, which scrapes the solid floating objects on the surface of the wastewater tank 1 from the edge to the center and pushes them into the waste cylinder 5. During the process, the contact rod 48 slides along the trajectory of the wave-shaped groove 49. When the contact rod 48 moves from the trough to the crest, the lower side wall of the wave-shaped groove 49 applies an upward thrust to the contact rod 48, forcing the movable rod 47 to slide upward against the tension of the tension spring 46. When the contact rod 48 crosses the crest, the restoring force of the tension spring 46 pulls the movable rod 47 downward. The cooperation between the movable rod 47 and the wave-shaped groove 49 causes the scraper 410 to slide up and down simultaneously while revolving in a circle with the movable rod 47.

[0025] The critical force state of the abutment rod 48 as it climbs upward along the corrugated groove 49 must satisfy the following dynamic equilibrium equations:

[0026] In the formula: The rotating mechanism 4 transmits the horizontal driving force to the contact rod 48 in the circumferential tangential direction; The angle between the surface of the rising section of the wave-shaped groove 49 and the horizontal plane; The total mass of the synchronous lifting components of the sliding sleeve 45, the movable rod 47, the abutment rod 48, and the scraper 410; It is the acceleration due to gravity; The spring constant is 46. This represents the upward tensile displacement of tension spring 46. This refers to the frictional resistance generated by the sliding component as a whole.

[0027] The scraper 410 scrapes away the dirt adhering to the inner wall of the wastewater tank 1 during its movement, preventing dirt from accumulating. Example

[0028] Please see Figure 1-8 Based on the above embodiment 1, the upper half of the outer wall of the wastewater tank 1 is provided with multiple overflow holes, and an annular water collection trough 8 is fixedly connected to the outer wall of the wastewater tank 1. The water collection trough 8 covers the outside of the multiple overflow holes. Two inclined and symmetrically arranged water collection plates 9 are fixedly connected to the bottom of the inner wall of the water collection trough 8. A water pipe 10 is fixedly connected to the bottom end of the lowest point of the two water collection plates 9 on the outer wall of the wastewater tank 1.

[0029] Working principle: After the scraping mechanism 3 separates the floating matter in the upper layer into the waste cylinder 5, the water level of the wastewater in the middle and lower layers of the wastewater tank 1 continues to rise. When the water level reaches the height of the overflow hole, the separated wastewater passes through the overflow hole into the water collection tank 8. The wastewater entering the water collection tank 8 flows along the inclined water collection plate 9 and flows to the water pipe 10 for discharge. Example

[0030] Please see Figure 1-8 Based on the above embodiments one and two, a guide mechanism 6 and a shaking mechanism 7 are provided above the center of the spiral collecting plate 32; The guiding mechanism 6 includes a fixed rod 62 vertically arranged at the center of the inner wall of the waste cylinder 5. The fixed rod 62 is welded and fixed to the inner wall of the waste cylinder 5 by multiple connecting rods 61 distributed around it. A movable sleeve 63 is slidably sleeved on the upper outer wall of the fixed rod 62. A conical guide scraper 64 is fixedly sleeved on the upper part of the outer wall of the movable sleeve 63. The guide scraper 64 is located directly above the discharge end of the spiral collection plate 32.

[0031] The vibration mechanism 7 includes a hexagonal shaft 71 fixedly connected to the top of the inner wall of the movable sleeve 63. A hexagonal groove matching the hexagonal shaft 71 is formed at the top of the fixed rod 62. The hexagonal shaft 71 is inserted vertically downwards and slides within the hexagonal groove. The hexagonal structure restricts the circumferential rotation of the movable sleeve 63 while allowing it to slide up and down. A spring 72 is installed on the bottom surface of the hexagonal groove, with its top pressing upwards against the bottom surface of the hexagonal shaft 71, providing an upward thrust. A vibration mechanism is also provided inside the waste cylinder 5 on the outside of the movable sleeve 63. The sleeve 73, the vibrating sleeve 73, and the movable sleeve 63 are all tapered in shape, with the upper part larger than the lower part. The inner wall of the vibrating sleeve 73 is fixedly connected to the outer wall of the movable sleeve 63 by multiple horizontal synchronizing rods 74, so that the vibrating sleeve 73 and the movable sleeve 63 rise and fall synchronously. At the same time, multiple downward protruding protrusions 75 are fixedly connected at equal intervals along the circumferential direction on the inner bottom of the rotating sleeve 31. An outwardly protruding push rod 76 is fixedly connected to the upper part of the outer wall of the movable sleeve 63. The end of the push rod 76 is located directly below the movement trajectory of the protrusion 75, and the outer wall of the push rod 76 is attached to the lower surface of the protrusion 75.

[0032] Working principle: When the rotating sleeve 31 rotates under the drive of the ring 33, the multiple protrusions 75 at the bottom of the rotating sleeve 31 rotate accordingly. The limiting effect of the fixed rod 62 and the hexagonal shaft 71 keeps the push rod 76, the movable sleeve 63, the vibrating sleeve 73 and the guide scraper 64 stationary. When the rotating sleeve 31 drives the protrusions 75 to move above the push rod 76, the inclined surface of the protrusions 75 presses the push rod 76 downward.

[0033] The critical condition for push rod 76 to descend under pressure must satisfy the following dynamic equation:

[0034] In the formula: The normal thrust applied to the inclined surface of the protrusion 75 on the push rod 76; The angle between the inclined plane pressed down by the 75-degree bump and the horizontal plane; The spring constant is 72. This is the displacement caused by the compression of spring 72; The overall mass of the hexagonal shaft 71, movable sleeve 63, guide scraper 64, synchronizing rod 74, push rod 76, and vibrating sleeve 73.

[0035] Under the downward pressure of the protrusion 75, the push rod 76 drives the movable sleeve 63 and the guide scraper 64 to slide downward against the elastic force of the spring 72. When the protrusion 75 rotates past the push rod 76 and disengages, the push rod 76 loses its downward pressure, the spring 72 releases its elastic force, and the hexagonal shaft 71, the movable sleeve 63 and the guide scraper 64 bounce upward and reset. As the rotating sleeve 31 rotates continuously, multiple protrusions 75 alternately sweep past the push rod 76, forming a continuous knocking action. The guide scraper 64 and the vibrating sleeve 73 generate up and down vibration in the waste cylinder 5. The vibration causes the sticky solid waste to detach from the surface of the guide scraper 64. Under the guidance of the guide scraper 64, the solid waste slides down along the inner wall of the vibrating sleeve 73 and the movable sleeve 63 and enters the waste cylinder 5 for discharge, preventing solid waste blockage.

[0036] This invention provides a wastewater treatment device for animal husbandry. Many methods and approaches exist to implement this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
