Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for pig farms. Background Technology

[0002] To ensure the survival rate of pigs raised in pig farms, it is necessary to ensure that the hygiene of the pig sheds meets the standards. Therefore, it is necessary to frequently wash the pig pens to flush out the pig manure. In order to prevent the wastewater generated from breeding from polluting the environment, the wastewater needs to be treated to meet the standards before being discharged or reused. The existing technology involves adding the wastewater into a treatment tank, which is equipped with a filter screen. The filter screen filters out the fecal impurities in the wastewater. The filtered water is then disinfected with disinfectant to achieve the effect of wastewater treatment.

[0003] A search revealed a patent publication number CN219363426U published on July 18, 2023, for a wastewater treatment device for pig farms. The device is described as follows: it includes a support plate, support columns below the support plate, a purification tank on the support plate, a water inlet on one side of the purification tank connected to a water inlet pipe, a support ring inside the purification tank, a filter screen on the support ring, a first motor on the purification tank, a rotating shaft connected to the rotor shaft of the first motor, the rotating shaft inserted into the purification tank and extending through the filter screen, first brush plates connected to both sides of the rotating shaft above the filter screen, and second brush plates connected to both sides of the rotating shaft below the filter screen.

[0004] While the aforementioned existing technical solution can prevent feces and other impurities from easily adsorbing and sticking to the filter screen and clogging the filter screen's mesh, thus affecting filtration efficiency, the device relies on the first brush plate to drive the feces to rotate and move, resulting in a slow discharge speed of the waste from the drain pipe and thus low working efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a wastewater treatment device for pig farms, which solves the problem mentioned in the background technology that the wastewater is discharged slowly from the sewage pipe, resulting in low work efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device for pig farms, comprising a treatment box, including a base plate fixedly connected to the bottom of the treatment box, with support legs fixedly connected to the four corners of the bottom of the base plate, a drain pipe penetrating the base plate at the bottom of the treatment box, a first solenoid valve on the drain pipe, a sludge inlet pipe at the top of the treatment box, a filter plate inside the treatment box, and sludge discharge channels cooperating with the filter plate at both ends of the treatment box, two baffles rotatably connected to the outer wall of the treatment box respectively cooperating with the two sludge discharge channels, and connecting plates at both ends of the two baffles, two fixing blocks fixedly connected to the outer wall of the treatment box, and two electric push rods rotatably connected to the two fixing blocks, with one end of each of the four electric push rods connected to... Four connecting plates are rotatably connected. A reciprocating threaded rod is rotatably connected to the inner wall of the treatment box. A threaded component is threadedly connected to the reciprocating threaded rod. An elastic cleaning plate that is tightly attached to the filter plate is fixedly connected to the bottom end of the threaded component. Two limiting rods are provided on the inner wall of the treatment box. A limiting component that is slidably connected to the limiting rod is provided on the threaded component. A first motor connected to the reciprocating threaded rod is installed on the outer wall of the treatment box. A partition plate is fixedly connected inside the treatment box. A second motor is installed at the bottom end of the partition plate. The output end of the second motor passes through the partition plate and is connected to a rotating rod. Multiple evenly distributed stirring rods are provided on the rotating rod. A feed pipe is provided on the outer wall of the treatment box. A water pipe is provided at the bottom end of the partition plate. A second solenoid valve is provided on the water pipe. A multi-layer filter adsorption box is provided inside the treatment box.

[0009] By adopting the above technical solution, sewage is injected into the treatment tank through the inlet pipe, allowing the filter plate to filter the sewage. The first motor is started, driving the reciprocating threaded rod to rotate. The reciprocating threaded rod drives the threaded component to move back and forth, which in turn moves the elastic cleaning plate, cleaning the filter plate and preventing fecal impurities from clogging it and affecting the drainage speed. The filtered water falls through the filter plate onto the separator plate. At this point, alum solution is added through the feed pipe to mix the alum solution with the water. The second motor is started, driving the rotating rod and stirring rod to rotate, thus stirring the alum solution and water. To increase the fusion speed, the alum solution adsorbs and settles impurities in the water. At this point, the second solenoid valve is opened, allowing water and sediment to fall through the water pipe onto the multi-layer filter adsorption box, thus enabling the multi-layer filter adsorption box to adsorb the sediment in the water. Then, the first solenoid valve is opened, allowing the filtered and adsorbed water to be discharged through the drain pipe. At this point, four electric push rods are activated simultaneously, pushing two baffles to rotate and detach from the outer wall of the treatment box. The elastic cleaning plate then pushes the fecal impurities on the filter plate through two sewage discharge channels to be discharged from the equipment, thereby increasing the speed of sewage discharge and achieving the purpose of improving work efficiency.

[0010] Optionally, both baffles are provided with a sealing gasket at one end near the processing box, with one end of the sealing gasket tightly against the outer wall of the processing box.

[0011] By adopting the above technical solution, the sealing gasket is used to improve the sealing between the baffle and the treatment tank, thereby preventing sewage from flowing out from the gap between the baffle and the treatment tank.

[0012] Optionally, the processing box has a placement frame inside, the filter plate is placed on the placement frame, two matching positioning frames are fixedly connected to the inner side wall of the processing box, the multi-layer filter adsorption box is slidably connected between the two positioning frames, a maintenance port matching the multi-layer filter adsorption box is opened on the outer wall of the processing box, and a sealing plate is bolted to the outer wall of the processing box.

[0013] By adopting the above technical solution, after long-term use, the baffle can be opened and one end of the filter plate can be pulled to make one end of the filter plate tilt up, so as to facilitate the removal and replacement of the filter plate. The sealing plate can be opened, and the multi-layer filter adsorption box can be pulled out from the maintenance port, thus facilitating the replacement of the multi-layer filter adsorption box.

[0014] Optionally, the top of the processing box is provided with a sliding groove, and the top of the threaded part is fixedly connected to a balance block that passes through the sliding groove. The top of the processing box is fixedly connected to a mounting bracket, and a balance rod is fixedly connected inside the mounting bracket. The balance rod is slidably connected to the balance block.

[0015] By adopting the above technical solution, the balance bar and the balance block cooperate to keep the threaded part and the balance block in balance when the threaded part drives the elastic cleaning plate to move, so as to avoid the threaded part from deflecting.

[0016] Optionally, two guide plates that cooperate with the sewage discharge channel are fixedly connected to the outer wall of the treatment box, and side plates are provided at both ends of the two guide plates.

[0017] By adopting the above technical solution, the guide plate is used to guide the discharged fecal impurities, so as to facilitate unified collection and prevent fecal impurities from flowing onto the outer wall of the equipment, causing dirt to accumulate on the outer wall of the equipment. The side plate is used to constrain and limit the dirt on the guide plate to prevent the dirt from flowing to the side.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] The pig farm uses a wastewater treatment system. Wastewater is injected into the treatment tank through the inlet pipe, where a filter plate filters the wastewater. A first motor is activated, driving a reciprocating screw rod. This screw rod drives a threaded component to move back and forth, which in turn moves an elastic cleaning plate. This cleaning plate cleans the filter plate, preventing fecal impurities from clogging it and affecting the drainage speed. The filtered water falls through the filter plate onto a separator plate. At this point, alum solution is added through the feed pipe to mix the alum solution with the water. A second motor is then activated, driving a rotating rod and a stirring rod to agitate the alum solution and water. Stirring increases the mixing speed, allowing the alum solution to adsorb and settle impurities in the water. Then, the second solenoid valve is opened, allowing water and sediment to fall through the water pipe onto the multi-layer filter adsorption box. This allows the multi-layer filter adsorption box to adsorb the sediment in the water. Next, the first solenoid valve is opened, allowing the filtered water to drain through the drain pipe. Simultaneously, four electric push rods are activated, pushing two baffles to rotate and detach from the outer wall of the treatment tank. The elastic cleaning plate then pushes the fecal impurities on the filter plate through two drain channels to discharge them from the equipment, thus increasing the speed of waste removal and improving work efficiency.
