Description

Technical Field

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

[0002] Animal husbandry is an important industry for rural development in my country. In recent years, with the continuous expansion of the scale of animal husbandry and the rapid increase in the number of animals raised, a large amount of livestock and poultry manure and wastewater have become sources of pollution. If the pollution generated by these farms is not treated in time, it will cause great harm to the environment, leading to the deterioration of the ecological environment, the decline in the quality of livestock and poultry products, and endangering human health. The lag in pollution control technology in the animal husbandry industry will seriously restrict the sustainable development of the industry.

[0003] For example, CN108623032A discloses a wastewater purification device for aquaculture, comprising a body, a wastewater treatment chamber, an inlet, and a drive assembly. The wastewater treatment chamber is located inside the body, with an inlet connected to the top center of the chamber and an outlet located below the left side wall. The drive assembly is located at the bottom of the body. The device is characterized by vertical partitions welded to both sides of the top of the wastewater treatment chamber, with activated carbon storage tanks fixedly connected to the opposite sides of each partition. A servo motor is installed in the middle of the drive assembly, and a first gear is fixedly welded to the output end of the servo motor. The first gear is positioned directly above the servo motor, and second gears are symmetrically arranged on both sides of the first gear. This invention ensures thorough solid-liquid separation of wastewater and efficient wastewater treatment. The entire wastewater treatment process is highly efficient and environmentally friendly, significantly reducing energy consumption and making it suitable for widespread application.

[0004] Solid-liquid separation is achieved through screens, but solid waste tends to accumulate on top of the screen, which affects filtration efficiency and thus the purification efficiency of wastewater. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a wastewater treatment device for chicken farms, 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 chicken farms, including a purification box, an outlet provided on the side of the purification box, a screen provided inside the purification box, a plurality of holes opened inside the screen, a cleaning mechanism provided inside the purification box, the cleaning mechanism including an electric push rod, the electric push rod being fixedly connected to the right inner wall of the purification box, a cleaning plate being fixedly connected to the left end of the electric push rod, and the cleaning plate contacting the top of the screen.

[0007] Preferably, a telescopic rod is fixedly connected to the bottom inner wall of the purification box, the telescopic rod is fixedly connected to the screen, a first spring is sleeved on the outer wall of the telescopic rod, and a first horizontal plate is fixedly connected to the top of the screen.

[0008] Preferably, the front of the first horizontal plate is provided with a first connecting groove, the middle section of the first connecting groove is horizontally arranged, the left end of the first connecting groove is obliquely arranged, and the left is higher than the right. The back of the cleaning plate is fixedly connected to a first fixing rod, and the first connecting groove is sleeved on the outer wall of the first fixing rod.

[0009] Preferably, a first fixing plate is fixedly connected to the bottom inner wall of the purification box, and a second horizontal plate is fixedly connected to the top of the first fixing plate. A cleaning roller is rotatably connected to the top of the second horizontal plate. When the device is started, the electric push rod of the cleaning mechanism starts to work, driving the cleaning plate to move back and forth along the screen surface. The cleaning plate directly scrapes most of the solid waste accumulated on the top of the screen to the left, completing the initial surface cleaning. At the same time as the cleaning plate moves, the first fixing rod on its back moves in the first connecting groove of the first horizontal plate. When the first fixing rod moves to the inclined part at the left end of the first connecting groove, it will force the entire screen to overcome the elastic force of the first spring and move downward. The downward movement of the screen causes the fixing cylinder fixedly connected to its bottom to move downward synchronously. At this time, the cleaning roller fixed to the second horizontal plate will poke into the fixing cylinder and the corresponding screen hole, pushing out the impurities blocked deep in the hole, completing the cleaning of the hole.

[0010] Preferably, the purification box is provided with an auxiliary mechanism, which includes a fixed cylinder, which is fixedly connected to the screen and communicates with the holes. The outer wall of the fixed cylinder has an arc-shaped hole, and the outer wall of the cleaning roller is fixedly connected with a second fixed rod.

[0011] Preferably, a connecting plate is fixedly connected to the top of the screen, a groove is formed at the bottom of the connecting plate, a slider is slidably connected inside the groove, a second spring is fixedly connected between the slider and the groove, an elastic rod is fixedly connected to the bottom of the slider, a first scraper is fixedly connected to the bottom of the elastic rod, the first scraper is positioned at the top of the hole, a third fixing rod is fixedly connected to the back of the first scraper, a second connecting groove is formed on the inner wall of the purification box, the second connecting groove is fitted onto the outer wall of the third fixing rod, the upper end of the second connecting groove is vertically oriented, and the lower end of the second connecting groove is obliquely oriented. When the screen moves downward, the fixing cylinder fixedly connected to its bottom moves downward synchronously. At this time, the cleaning roller fixed to the second horizontal plate will rotate and pierce into the fixing cylinder due to the cooperation of the second fixing rod and the arc-shaped hole. The cleaning roller pushes out impurities deep inside the screen holes, completing a deep cleaning of the holes. As the screen moves downward, the connecting plate moves downward simultaneously, driving the first scraper downward via the slider. The first scraper moves downward, driving the third fixed rod downward. When the third fixed rod moves inside the second connecting groove, it forces the first scraper to move laterally at the bottom of the second connecting groove, effectively sweeping away the impurities pushed out from the top of the cleaning roller and the edges of the holes. Due to the elastic rod, there is no interference between the first scraper and the cleaning roller. The first scraper acts like a "broom," promptly sweeping away the impurities pushed out by the cleaning roller or remaining on the top of the holes, effectively preventing impurities from falling back into the cleaned holes due to gravity or water flow.

[0012] Preferably, the purification chamber is provided with a feeding mechanism, which includes a feeding plate. A feeding port is provided on the left side of the purification chamber. The feeding plate is hinged to the bottom of the screen. A third spring is fixedly connected between the feeding plate and the screen. An abutment rod is fixedly connected to the right side of the feeding plate. A corrugated groove is provided on the left inner wall of the purification chamber. The abutment rod contacts the corrugated groove.

[0013] Preferably, a second fixing plate is fixedly connected to the left side of the purification box, and a second scraper is hinged to the bottom of the discharge port. A fourth spring is fixedly connected between the second scraper and the second fixing plate. The solid waste collected by the cleaning plate and the first scraper on the left side of the screen falls onto the discharge plate hinged to the bottom of the screen under the action of gravity. The continuous up and down movement of the screen drives the discharge plate to move synchronously, and the abutment rod on its right side rolls in the corrugated groove on the inner wall of the purification box. The undulating contour of the corrugated groove forces the discharge plate to swing periodically around the hinge point, forming a "bumping" effect, which smoothly discharges the solid waste from the discharge port. When the discharge plate moves up, it scrapes the impurities on the top of the first scraper from the left and right sides of the second scraper, effectively preventing impurities from remaining on the first scraper.

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This wastewater treatment equipment for chicken farms, during operation, involves a cleaning mechanism where the movement of the first fixed rod within the first connecting groove drives a cleaning plate to scrape away solid waste from the screen surface. The movement of the first fixed rod within the connecting groove forces the screen to move horizontally while simultaneously displacing it downwards. This downward movement of the screen allows the cleaning roller to precisely penetrate the screen's holes, effectively removing impurities deep within the holes, thus solving the technical problem of easy clogging of the screen holes and enhancing the self-cleaning effect.

[0015] 2. This wastewater treatment equipment for chicken farms, through the coordinated action of a fixed cylinder, arc-shaped holes, cleaning rollers, and a second fixed rod, allows the cleaning rollers to penetrate deep into the fixed cylinder during the up-and-down movement of the screen, rotating and scraping the inner wall of the holes to effectively solve the problem of fine particles clogging the screen holes, ensuring the long-term unobstructed flow and filtration performance of the screen. Furthermore, the third fixed rod, connected to the first scraper, moves in the second connecting groove, causing the first scraper to move laterally during the cleaning roller's brushing and upward movement, thereby sweeping away impurities pushed out by the cleaning roller or remaining at the top of the holes, effectively preventing impurities from falling back into the cleared holes due to gravity or water flow.

[0016] 3. This wastewater treatment equipment for chicken farms uses a feeding mechanism that, through the cooperation of a feeding plate, a third spring, a contact rod, and a corrugated trough, converts the vibration of the screen into the periodic up-and-down shaking of the feeding plate. This achieves the discharge of scraped solid waste, avoids the accumulation of waste on the feeding plate, ensures the continuous operation of the device, and the second scraper can clean the residual impurities on the top of the first scraper, improving the cleaning effect of the second scraper.

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.

[0020] Please see Figure 1-7One embodiment of the present invention is as follows: a wastewater treatment device for chicken farms, including a purification tank 1, an outlet 2 on the side of the purification tank 1, a screen 3 inside the purification tank 1 with several holes inside the screen 3, a cleaning mechanism 4 inside the purification tank 1, the cleaning mechanism 4 including an electric push rod 411, the electric push rod 411 being fixedly connected to the right inner wall of the purification tank 1, a cleaning plate 412 being fixedly connected to the left end of the electric push rod 411, the cleaning plate 412 contacting the top of the screen 3, a telescopic rod 413 being fixedly connected to the bottom inner wall of the purification tank 1, the telescopic rod 413 being fixedly connected to the screen 3, a first spring 414 being sleeved on the outer wall of the telescopic rod 413, and the top of the screen 3 being fixedly connected to... A first horizontal plate 415 has a first connecting groove 416 on its front side. The middle section of the first connecting groove 416 is horizontally oriented, while the left end is obliquely oriented, with the left side higher than the right. A first fixing rod 417 is fixedly connected to the back of the cleaning plate 412. The first connecting groove 416 is fitted onto the outer wall of the first fixing rod 417. A first fixing plate 418 is fixedly connected to the bottom inner wall of the purification box 1. A second horizontal plate 419 is fixedly connected to the top of the first fixing plate 418. A cleaning roller 420 is rotatably connected to the top of the second horizontal plate 419. When the device is started, the electric push rod 411 of the cleaning mechanism 4 starts working, driving the cleaning plate 412 to move back and forth along the surface of the screen 3. The cleaning plate 412 directly scrapes most of the solid waste accumulated on the top of the screen 3 to the left, completing the initial surface cleaning. While the cleaning plate 412 is moving, the first fixing rod 417 on its back moves within the first connecting groove 416 of the first horizontal plate 415. When the first fixing rod 417 moves to the inclined portion at the left end of the first connecting groove 416, it forces the entire screen 3 to move downward against the elastic force of the first spring 414. The downward movement of the screen 3 causes the fixing cylinder 511 fixedly connected to its bottom to move downward simultaneously. At this time, the cleaning roller 420 fixed on the second horizontal plate 419 will poke into the fixing cylinder 511 and the corresponding screen 3 holes, pushing out the impurities blocked deep in the holes, thus completing the cleaning of the inside of the holes.

[0021] Working principle: When the device is started, the electric push rod 411 of the cleaning mechanism 4 starts to work, driving the cleaning plate 412 to move back and forth along the surface of the screen 3. The cleaning plate 412 directly scrapes most of the solid waste accumulated on the top of the screen 3 to the left, completing the initial surface cleaning. At the same time as the cleaning plate 412 moves, the first fixing rod 417 on its back moves in the first connecting groove 416 of the first horizontal plate 415. When the first fixing rod 417 moves to the inclined part at the left end of the first connecting groove 416, it will force the entire screen 3 to overcome the elastic force of the first spring 414 and move downward. The downward movement of the screen 3 causes the fixing cylinder 511 fixed to its bottom to move downward synchronously. At this time, the cleaning roller 420 fixed on the second horizontal plate 419 will poke into the fixing cylinder 511 and the corresponding screen 3 holes, pushing out the impurities blocked deep in the holes, completing the cleaning of the inside of the holes.

[0022] Please see Figure 1-7Based on the above embodiments, in another embodiment of the present invention, an auxiliary mechanism 5 is provided inside the purification box 1. The auxiliary mechanism 5 includes a fixed cylinder 511, which is fixedly connected to the screen 3 and communicates with the holes.

The first scraper 519 is positioned at the top of the hole. A third fixing rod 520 is fixedly connected to the back of the first scraper 519. A second connecting groove 521 is provided on the inner wall of the purification box 1. The second connecting groove 521 is fitted onto the outer wall of the third fixing rod 520. The upper end of the second connecting groove 521 is vertically oriented, and the lower end is obliquely oriented. The downward movement of the screen 3 causes the fixing cylinder 51 fixedly connected to its bottom to... 1. Simultaneously moving downwards, the cleaning roller 420 fixed on the second horizontal plate 419, due to the cooperation between the second fixed rod 514 and the arc-shaped hole 512, will rotate and penetrate into the fixed cylinder 511 and the corresponding screen 3 holes, dislodging impurities blocked deep inside the holes, completing the deep cleaning of the holes. When the screen 3 moves downwards, the connecting plate 515 will move downwards synchronously, and at the same time, it will drive the first scraper 519 downwards through the slider 516. When the first scraper 519 moves downwards synchronously, it will drive the third fixed rod 520 downwards. When the third fixing rod 520 moves inside the second connecting groove 521, it will force the first scraper 519 to move laterally at the bottom of the second connecting groove 521. This will sweep away the impurities pushed out from the top of the cleaning roller 420 and the edge of the hole. Due to the action of the elastic rod 518, the first scraper 519 will not interfere with the cleaning roller 420. The first scraper 519 will promptly sweep away the impurities pushed out by the cleaning roller 420 or remaining on the top of the hole, effectively preventing the impurities from falling back into the cleared hole due to gravity or water flow.

[0023] Working principle: The downward movement of the screen 3 causes the fixed cylinder 511, which is fixedly connected to its bottom, to move downward synchronously. At this time, the cleaning roller 420, fixed on the second horizontal plate 419, rotates and inserts into the fixed cylinder 511 and the corresponding screen 3 holes due to the cooperation of the second fixed rod 514 and the arc-shaped hole 512, thus removing the impurities blocked deep in the holes and completing the deep cleaning of the holes. When the screen 3 moves downward, the connecting plate 515 moves downward synchronously, and at the same time, it drives the first scraper 519 downward through the slider 516. When the first scraper 519 moves downward synchronously, it will... The third fixing rod 520 is driven to descend. When the third fixing rod 520 moves inside the second connecting groove 521, it will force the first scraper 519 to move laterally at the bottom of the second connecting groove 521. This will sweep away the impurities pushed out from the top of the cleaning roller 420 and the edge of the hole. Due to the action of the elastic rod 518, the first scraper 519 will not interfere with the cleaning roller 420. The first scraper 519 will promptly sweep away the impurities pushed out by the cleaning roller 420 or remaining on the top of the hole, effectively preventing the impurities from falling back into the cleared hole due to gravity or water flow.

The solid waste collected by the cleaning plate 412 on the left side of the screen 3 falls onto the feeding plate 611 hinged to the bottom of the screen 3 under the action of gravity. The continuous up-and-down movement of the screen 3 drives the feeding plate 611 to move synchronously, and the abutment rod 613 on its right side rolls in the corrugated groove 614 on the inner wall of the purification box 1. The undulating contour of the corrugated groove 614 forces the feeding plate 611 to swing periodically around the hinge point, forming a "bumping" effect, which smoothly discharges solid waste from the feeding port. When the feeding plate 611 moves upward, it scrapes the impurities on the top of the first scraper 519 from the left and right sides of the second scraper 617, effectively preventing impurities from remaining on the first scraper 519.
