Description

Technical Field

[0001] This invention relates to a filtration device, and more particularly to a wastewater filtration device for pig farms. Background Technology

[0002] Animal husbandry refers to the production sector that raises livestock and poultry through grazing, penning, or a combination of both to obtain animal products or draft animals. Large-scale pig farms, in particular, possess advanced livestock and poultry breeding techniques and unified management, reducing costs and improving economic efficiency. However, during the breeding process, in order to improve pork quality, farmers need to control the pigs' growth environment and ensure they can grow in a favorable environment. Therefore, the pig farm needs to be cleaned daily by flushing water. This cleaning water mixes with the pig manure and urine already present on the farm, resulting in a large amount of wastewater. Wastewater filtration devices are required for preliminary treatment of this wastewater.

[0003] For example, Chinese Patent Publication No. CN222738589U discloses a pig farm wastewater filtration device, specifically relating to the field of pig farm wastewater treatment technology. The pig farm wastewater filtration device includes a separation tank and a purification tank. A rectangular filter screen is installed inside the separation tank, dividing it into two parts. One part has a feed pipe and a water inlet pipe at its top, with the water inlet pipe connected to a high-pressure water spray head. The other part of the separation tank is connected to the purification tank via a first water pump. An outlet is located at the bottom of the side wall of the purification tank. This device effectively filters pig farm manure and wastewater, separating them efficiently. It has a simple structure, increasing practicality, and provides good purification effect and high efficiency for wastewater treatment in large-scale pig farms. However, this patent has the following problems: First, simply using a filter to separate solids and liquids from pig manure in a pig farm will result in a large amount of pig manure and other solids clogging the filter surface as it is used, leading to the problem of filter blockage. Secondly, the separated solid pig manure is difficult to extract directly using pumps or other means. Firstly, the pig manure needs to be manually dug out periodically. Secondly, the treatment of manure water needs to be stopped during the digging process, which reduces the efficiency of sewage treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater filtration device for pig farms to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater filtration device for pig farms, comprising a primary collection tank, a solid-liquid separation cylinder inclinedly arranged above the primary collection tank, support frames fixedly connected to both sides of the solid-liquid separation cylinder, the other end of the support frames fixedly connected to the inner wall of the primary collection tank, a liquid inlet fixedly connected to the upper end of the solid-liquid separation cylinder, a plurality of filter holes opened on the outer wall of the solid-liquid separation cylinder, an auger rotatably installed inside the solid-liquid separation cylinder, the auger blades fitting against the inner wall of the solid-liquid separation cylinder, a base fixedly connected to the rear end of the primary collection tank, a movable seat slidably installed on the base, and two collection boxes placed on the movable seat, the collection boxes being located below the rear end of the solid-liquid separation cylinder.

[0006] Preferably, a drain outlet is fixedly connected to the front of the primary collection tank, and a control panel is fixedly connected to one side of the primary collection tank.

[0007] Preferably, a drive motor is fixedly connected to the front end of the solid-liquid separation cylinder, and the output end of the drive motor is fixedly connected to one end of the auger.

[0008] Preferably, a gas storage cylinder is fixedly connected to the solid-liquid separation cylinder via a mounting base, and a gas delivery pipe is fixedly connected to the front end of the gas storage cylinder, with the other end of the gas delivery pipe communicating with the interior of the solid-liquid separation cylinder.

[0009] Preferably, an air pump is fixedly connected to the solid-liquid separation cylinder via a mounting base, and the output end of the air pump is fixedly connected to the rear end of the gas storage cylinder.

[0010] Preferably, a solenoid valve is connected in series on the gas pipeline, and the solenoid valve is used to control the opening and closing of the gas pipeline.

[0011] Preferably, a limiting groove is provided on the base, and a limiting slider is fixedly connected to the bottom of the movable seat, with the limiting slider slidingly engaging with the limiting groove.

[0012] Preferably, a threaded screw is rotatably installed in the limiting slide groove, and a threaded through hole is opened in the limiting slider, the threaded through hole being threadedly engaged with the threaded screw.

[0013] Preferably, an adjustment motor is fixedly connected to one side of the base, and the output end of the adjustment motor is fixedly connected to one end of the threaded screw.

[0014] Preferably, a raised edge is fixedly connected to the movable seat, and the raised edge cooperates with the collection box.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By starting the drive motor, the auger can be rotated. The rotation of the auger causes the solids inside the solid-liquid separation cylinder to be discharged from the opening, thus preventing the separated solids from clogging the filter holes and preventing the sewage from flowing through the filter holes to the primary collection tank later. 2. The gas cylinder stores a certain amount of high-pressure gas. When solids clog the filter holes, the solenoid valve is opened, and the high-pressure air inside the gas cylinder is instantly delivered to the solid-liquid separation cylinder through the gas delivery pipe. The impact force of the instantaneous influx of high-pressure gas washes away the debris clogging the filter holes. 3. There are two collection boxes. When one collection box is full, the moving seat moves both collection boxes, so that the other empty collection box moves to the lower end of the solid-liquid separation cylinder opening. Then the full collection box is moved to the side. There is no need to stop the machine to change the container, which increases the processing efficiency of the device. Attached Figure Description

[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] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0020] Example 1 A wastewater filtration device for pig farms includes a primary collection tank 1. A solid-liquid separation cylinder 2 is inclinedly arranged above the primary collection tank 1. Support frames 205 are fixed to both sides of the solid-liquid separation cylinder 2. The other end of the support frame 205 is fixed to the inner wall of the primary collection tank 1. An inlet 201 is fixed to the upper end of the solid-liquid separation cylinder 2. Several filter holes 202 are opened on the outer wall of the solid-liquid separation cylinder 2. An auger 204 is rotatably installed inside the solid-liquid separation cylinder 2. The blades of the auger 204 are attached to the inner wall of the solid-liquid separation cylinder 2. A base 4 is fixed to the rear end of the primary collection tank 1. A movable seat 5 is slidably installed on the base 4. Two collection boxes 6 are placed on the movable seat 5. The collection boxes 6 are located below the rear end of the solid-liquid separation cylinder 2.

[0021] In this embodiment, the solid-liquid separation cylinder 2 is tilted and supported above the primary collection tank 1 by the support frame 205. The pig farm sewage pipe is connected to the inlet 201, and the sewage is then transported from the inlet 201 into the solid-liquid separation cylinder 2. Solid-liquid separation of the sewage is achieved by using the filter holes 202. The liquid part is discharged from the filter holes 202 and flows directly into the primary collection tank 1. At the same time, the solid-liquid separation cylinder 2 is tilted, with the front end of the solid-liquid separation cylinder 2 at a lower point and the rear opening at a higher point. This can prevent the sewage inside the solid-liquid separation cylinder 2 from overflowing directly from the opening, while the solids are retained in the solid-liquid separation cylinder. Inside the solid-liquid separation cylinder 2, the rotating auger 204 will cause the solids inside the solid-liquid separation cylinder 2 to be discharged from the opening. The collection box 6 is located at the lower end of the opening of the solid-liquid separation cylinder 2, and the solids will fall into the collection box 6 for collection. There are two collection boxes 6. When one collection box 6 is full, the moving seat 5 will move both collection boxes 6, so that the other empty collection box 6 will be moved to the lower end of the opening of the solid-liquid separation cylinder 2. Then the full collection box 6 will be moved to the side, and the solid waste inside the collection box 6 can be manually handled later. The transfer of solid waste can be completed without stopping the machine, which increases the processing efficiency of the device.

[0022] Example 2 A drain outlet 101 is fixedly connected to the front of the primary collection tank 1. A control panel 102 is fixedly connected to one side of the primary collection tank 1. A drive motor 203 is fixedly connected to the front end of the solid-liquid separation cylinder 2. The output end of the drive motor 203 is fixedly connected to one end of the auger 204. A gas storage cylinder 3 is fixedly connected to the solid-liquid separation cylinder 2 via a mounting base. A gas supply pipe 302 is fixedly connected to the front end of the gas storage cylinder 3. The other end of the gas supply pipe 302 communicates with the inside of the solid-liquid separation cylinder 2. An air pump 301 is fixedly connected to the solid-liquid separation cylinder 2 via a mounting base. The output end of the air pump 301 is fixedly connected to the rear end of the gas storage cylinder 3. A solenoid valve 303 is connected in series on the gas supply pipe 302. The solenoid valve 303 is used to control the opening and closing of the gas supply pipe 302.

[0023] In this embodiment, the liquid inside the primary collection tank 1 can be discharged through the drain outlet 101 for secondary treatment. Starting the drive motor 203 can drive the auger 204 to rotate. The rotation of the auger 204 can cause the solids inside the solid-liquid separation cylinder 2 to move backward. The gas storage cylinder 3 stores a certain amount of high-pressure gas. After solids block the filter hole 202, the solenoid valve 303 is opened, and the high-pressure air inside the gas storage cylinder 3 will be instantly delivered to the solid-liquid separation cylinder 2 through the gas delivery pipe 302. The high-pressure air rushes into the solid-liquid separation cylinder 2 and blows out the solids inside the filter hole 202. Starting the air pump 301 can inject a certain amount of air into the gas storage cylinder 3, so that the gas storage cylinder 3 stores high-pressure air.

[0024] Example 3 A limiting groove 401 is provided on the base 4, and a limiting slider 501 is fixedly connected to the bottom of the movable seat 5. The limiting slider 501 slides in cooperation with the limiting groove 401. A threaded screw 402 is rotatably installed in the limiting groove 401. A threaded through hole is provided in the limiting slider 501, and the threaded through hole is threaded in cooperation with the threaded screw 402. An adjusting motor 403 is fixedly connected to one side of the base 4. The output end of the adjusting motor 403 is fixedly connected to one end of the threaded screw 402. A protrusion 502 is fixedly connected to the top of the movable seat 5, and the protrusion 502 cooperates with the collection box 6.

[0025] In this embodiment, starting the adjusting motor 403 can drive the threaded screw 402 to rotate. The threaded screw 402 engages with the threaded through hole, and the rotation of the threaded screw 402 can drive the limiting slider 501 to move. The movement of the limiting slider 501 can drive the moving seat 5 to move, which in turn drives the collection box 6 to move. The protruding edge 502 will be locked at the rear edge of the collection box 6, locking the collection box 6 onto the moving seat 5. Starting the drive motor 203 can drive the auger 204 to rotate, and the auger 204 rotates.

[0026] The working principle and usage process of this invention are as follows: The sewage pipe of the pig farm is connected to the inlet 201, and the sewage will be transported from the inlet 201 to the solid-liquid separation cylinder 2. The filter holes 202 are used to separate the solid and liquid in the sewage. The liquid part is discharged from the filter holes 202 and flows directly into the primary collection tank 1. The drive motor 203 is started to drive the auger 204 to rotate. The rotation of the auger 204 causes the solid inside the solid-liquid separation cylinder 2 to be discharged from the opening. The collection box 6 is located at the lower end of the opening of the solid-liquid separation cylinder 2, and the solid will fall into the collection box 6 for collection. There are two collection boxes 6. When one collection box 6 is full, the moving seat 5 moves both collection boxes 6, so that the other empty collection box 6 is moved to the lower end of the opening of the solid-liquid separation cylinder 2, and then the full collection box 6 is moved to the side. There is no need to stop the machine to change the container.
