Description

Technical Field

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

[0002] Livestock farming, especially large-scale cattle farms, generates a large amount of high-concentration organic wastewater during the production process. This type of wastewater usually contains abundant solid suspended matter such as manure, residual feed, animal hair, and bedding. It is characterized by high solid content, high fiber content, high viscosity, and easy putrefaction and odor. If it is discharged directly without effective treatment, it will cause serious pollution to water bodies, soil, and the surrounding environment.

[0003] Currently, the primary step in treating aquaculture wastewater is solid-liquid separation to reduce the load on subsequent biochemical treatment units and facilitate the resource utilization of solid waste. However, existing solid-liquid separation technologies and equipment suffer from the following significant problems in practical applications: Fixed screen or filter plate separation device: This type of equipment relies on wastewater to be separated by passing it through a fixed screen. When treating livestock wastewater, fine fibrous impurities, such as grass fibers and hair, are very easy to get tangled and clog the screen holes, causing the filtration efficiency to drop rapidly and the water flow to be obstructed. Frequent shutdowns are required for manual cleaning, which is not only labor-intensive and affects the continuity of treatment, but also often dirty and messy, and the working environment is harsh. Therefore, a wastewater treatment device for livestock cattle farming is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wastewater treatment device for cattle breeding, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a wastewater treatment device for cattle breeding, including a treatment tank, and further comprising: The bracket is fixedly connected to the bottom of the processing box to support the processing box; The solid-liquid separation mechanism is located inside the treatment tank and is used to separate solid waste from aquaculture wastewater; The unblocking mechanism is located inside the processing tank and above the solid-liquid separation mechanism, and is used to clean the solid-liquid separation mechanism. The solid-liquid separation mechanism includes: The separation cylinder is installed at an angle inside the treatment tank to separate solid waste from aquaculture wastewater; Two annular rails are fixedly connected to the outer wall of the separator cylinder; Multiple arc-shaped rails are connected to the front and rear sides of the inner wall of the processing box by two fixed rods, and the annular rail rotates on the arc-shaped rails.

[0006] Preferably, the solid-liquid separation mechanism further includes: The toothed ring is fixedly connected to the outer wall of the separator cylinder on one side of the annular rail and is used to drive the separator cylinder to rotate. The spiral ring is fixedly connected to the inner wall of the separation cylinder. When it rotates, it moves the solid waste in the aquaculture wastewater upwards along the separation cylinder.

[0007] Preferably, the inner wall of the processing box is equipped with a feed hopper, which is attached to the inclined lower side of the separation cylinder; A baffle plate is connected to the inner wall of the processing tank, and a water outlet is opened at the bottom of the baffle plate to discharge the liquid separated by the separation cylinder. The hopper is installed on the inner wall of the treatment tank, below the inclined upper side of the separation cylinder, and is used to discharge solid waste from the separated wastewater.

[0008] Preferably, the unblocking mechanism includes: Two arc-shaped fixing rods are fixedly connected to the front and rear inner walls of the processing box; The water pipe is slidably connected to the outer wall of two arc-shaped fixed rods, and multiple nozzles are fixedly connected to the lower part of the outer wall of the water pipe for spraying water onto the top of the outer wall of the separator for cleaning. The actuating component, located below the water pipe, is used to actuate the water pipe to slide along the outer wall of the arc-shaped fixing rod.

[0009] Preferably, the toggle assembly includes: Multiple arc-shaped levers are evenly distributed and fixedly connected to the outer wall of the ring rail; Two levers are fixedly connected to the outer wall of the water pipe, and their lower parts abut against the arc-shaped lever block; Multiple fixing rings are fixedly connected to the outer wall of the arc-shaped fixing rod in pairs and located on both sides of the water pipe; Multiple springs are fitted onto the outer wall of the arc-shaped fixing rod and located on both sides of the outer wall of the water pipe, for resetting the water pipe.

[0010] Preferably, the inner side of the arc-shaped rail is provided with a cavity, so that the arc-shaped lever can slide in the cavity; One end of the water pipe is connected to a corrugated hose for introducing clean water into one side of the water pipe.

[0011] Preferably, the separator is equipped with a self-cleaning mechanism for cleaning the inner wall of the separator. The self-cleaning mechanism includes: The cleaning rod is installed on the inner wall of the separator and is connected to the water pipe through two synchronous rods to follow the deflection of the water pipe; Multiple bristles are located on the outer wall of the cleaning rod to clean the inner wall of the separation cylinder.

[0012] Preferably, the outer wall of the separation cylinder has multiple through holes for separating wastewater from wastewater.

[0013] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This wastewater treatment device for livestock and cattle farming adopts a combination design of an inclined rotating separation cylinder and an internal spiral ring. During the rotation process, the spiral ring not only plays a role in stirring and preventing sedimentation, but more importantly, it can actively push solid waste to the upper part, realizing continuous and automatic discharge of solids. The liquid is quickly separated through the through holes in the cylinder wall under the action of gravity and centrifugal force. Compared with static screens or sedimentation tanks, this dynamic separation method has a higher processing speed and separation efficiency, and can meet the needs of farms with large wastewater production and continuous treatment requirements.

[0014] 2. This wastewater treatment device for livestock and cattle farming is driven entirely by the rotational power of the separation cylinder itself through the set unblocking mechanism and self-cleaning mechanism. When the separation cylinder rotates, the mechanical cooperation of the arc-shaped lever and the lever converts the rotational motion into the high-frequency reciprocating sliding of the water pipe, which drives the nozzle to perform reciprocating sweeping high-pressure flushing on the outer wall of the separation cylinder. This can promptly and thoroughly remove the fibers and sludge that block the through holes, ensuring that the filtration channel is always unobstructed.

[0015] 3. This wastewater treatment device for livestock and cattle breeding, through its self-cleaning mechanism and synchronized linkage, enables the internal cleaning rod and brush to swing synchronously, scraping and cleaning the surface of the spiral ring and the cylinder wall, preventing solid materials from adhering and caking, and ensuring the long-term reliability of the spiral conveying function.

[0018] 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.

[0019] Please see Figure 1-7 One embodiment of the present invention is: a wastewater treatment device for cattle breeding, comprising a treatment tank 1, and further comprising: Support bracket 2 is fixedly connected to the bottom of processing box 1 to support processing box 1; Solid-liquid separation mechanism 3 is installed inside the treatment tank 1 and is used to separate solid waste from aquaculture wastewater; The unblocking mechanism 4 is located inside the processing tank 1 and above the solid-liquid separation mechanism 3, and is used to clean the solid-liquid separation mechanism 3. The solid-liquid separation mechanism 3 includes: The separation cylinder 34 is inclinedly installed inside the treatment tank 1 and is used to separate solid waste from aquaculture wastewater; Two annular rails 31 are fixedly connected to the outer wall of the separation cylinder 34; Multiple arc-shaped rails 32 are connected to the front and rear sides of the inner wall of the processing box 1 by two fixed rods 33, and the annular rail 31 rotates on the arc-shaped rails 32.

[0020] The solid-liquid separation mechanism 3 also includes: The toothed ring 35 is fixedly connected to the outer wall of the separator 34 on one side of the annular rail 31 and is used to drive the separator 34 to rotate. The spiral ring 36 is fixedly connected to the inner wall of the separation cylinder 34. When it rotates, it agitates the solid waste in the aquaculture wastewater and moves it upward along the separation cylinder 34.

[0021] The inner wall of the processing box 1 is fitted with a feed hopper 5, which is attached to the inclined lower side of the separator 34. The guide plate 6 is connected to the inner wall of the processing tank 1, and the guide plate 6 has a water outlet hole at its inclined lower part for discharging the liquid separated by the separation cylinder 34. The feeding hopper 7 is installed on the inner wall of the treatment tank 1, located below the inclined upper side of the separation cylinder 34, and is used to discharge solid waste from the separated wastewater.

[0022] The unblocking mechanism 4 includes: Two arc-shaped fixing rods 41 are fixedly connected to the front and rear inner walls of the processing box 1; Water pipe 42 is slidably connected to the outer wall of two arc-shaped fixed rods 41, and multiple nozzles 43 are fixedly connected to the lower part of the outer wall of water pipe 42 for spraying water onto the top of the outer wall of separation cylinder 34 for cleaning. A toggle assembly 44 is located below the water pipe 42 and is used to toggle the water pipe 42 to slide on the outer wall of the arc-shaped fixing rod 41.

[0023] The toggle assembly 44 includes: Multiple arc-shaped levers 441 are equally divided and fixedly connected to the outer wall of the annular rail 31; Two levers 442 are fixedly connected to the outer wall of the water pipe 42, and their lower parts abut against the arc-shaped lever 441; Multiple fixing rings 444 are fixedly connected to the outer wall of the arc-shaped fixing rod 41 in pairs and located on both sides of the water pipe 42; Multiple springs 443 are sleeved on the outer wall of the arc-shaped fixing rod 41 and located on both sides of the outer wall of the water pipe 42, for resetting the water pipe 42.

[0024] The inner side of the arc-shaped rail 32 is provided with a cavity, so that the arc-shaped lever 441 can slide in the cavity; One end of the water pipe 42 is connected to a corrugated hose for introducing clean water into one side of the water pipe 42.

[0025] The separator 34 is equipped with a self-cleaning mechanism 8 for cleaning the inner wall of the separator 34. The self-cleaning mechanism 8 includes: The cleaning rod 82 is installed on the inner wall of the separation cylinder 34 and is connected to the water pipe 42 through two synchronizing rods 81 so as to follow the deflection of the water pipe 42. Multiple bristles 83 are set on the outer wall of the cleaning rod 82 to clean the inner wall of the separation cylinder 34.

[0026] The outer wall of the separator 34 has multiple through holes for separating wastewater from wastewater.

[0027] Working principle: The aquaculture wastewater enters the treatment tank 1 through the feed hopper 5 and flows into the lower end of the inclined separation cylinder 34. At this time, an external power, such as a motor, drives the gear ring 35 to rotate through the meshing of gears and gear ring 35, thereby driving the entire separation cylinder 34 to rotate slowly around its axis. The separation cylinder 34 is fixed to the arc-shaped rail 32 inside the treatment tank 1 by the annular rail 31 on its outer wall and rolls to obtain stable support. Inside the inclined separation cylinder 34, the wastewater tends to flow to one side of the cylinder due to gravity, while being agitated and lifted by the spiral ring 36 fixed to the inner wall of the cylinder. The spiral ring 36 pushes and transports the heavier solid waste, such as manure residue and feed residue, towards the higher end of the separation cylinder 34. During this process, the liquid is thrown out through multiple through holes on the wall of the separation cylinder 34 under the action of gravity and centrifugal force. The separated liquid falls onto the guide plate 6 below and is collected and discharged from the outlet hole at the bottom, entering the next stage of treatment unit or being discharged after meeting the standards. The solid waste pushed to the upper end of the separation cylinder 34 by the spiral ring 36 is finally discharged from the cylinder opening and falls into the feed hopper 7, thus realizing continuous separation and separate collection of solid and liquid.

[0028] Furthermore, to prevent the through holes on the outer wall of the separator 34 from being clogged by fine fibers or sludge, the device is equipped with a cleaning mechanism 4. This mechanism moves relative to the separator 34 to achieve periodic automatic cleaning. When the separator 34 rotates, multiple arc-shaped paddles 441 fixed on its outer wall annular rail 31 rotate accordingly. During rotation, the arc-shaped paddles 441 periodically actuate the lever 442 fixed on the water pipe 42, causing the entire water pipe 42 to slide along the arc-shaped fixed lever 41, compressing the spring 443 on one side. When the arc-shaped paddles 441 miss the lever 442, they push the lever 442... When the force disappears, the compressed spring 443 releases energy, quickly pulling the water pipe 42 back to its original position along the arc-shaped fixing rod 41. This reciprocating motion causes the water pipe 42 and the multiple nozzles 43 below it to sweep back and forth. High-pressure clean water enters the water pipe 42 through the corrugated hose and sprays out from the nozzles 43. As the nozzles 43 reciprocate under the drive of the water pipe 42, the water jet can thoroughly and efficiently wash the outer wall of the separator 34, flushing away the dirt blocking the through hole and keeping its filtration unobstructed. The cavity inside the arc-shaped rail 32 provides space for the movement of the arc-shaped lever 441.

[0029] Furthermore, the cleaning rod 82 is connected to the water pipe 42 via two synchronous rods 81. Therefore, when the water pipe 42 slides back and forth on the arc-shaped fixed rod 41, it will drive the cleaning rod 82 to swing synchronously inside the separation cylinder 34. The outer wall of the cleaning rod 82 is equipped with multiple bristles 83, and its swing trajectory corresponds exactly to the area of ​​the internal spiral ring 36. During the swing, the bristles 83 can scrape and clean the surface of the spiral ring 36 and part of the inner wall of the separation cylinder 34, preventing solid waste from excessively adhering and caking on the inner wall and the spiral ring 36, thus ensuring the continuous effectiveness of the spiral conveying function.
