Description

Technical Field

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

[0002] When raising black pigs in farms, the wastewater from these farms contains a large amount of pollutants such as organic matter, nitrogen, phosphorus, and pathogenic microorganisms. Therefore, wastewater treatment devices (such as solid-liquid separators) are usually used to treat the wastewater scientifically and effectively before it is discharged. This effectively removes harmful substances from the wastewater, significantly reduces the content of these pollutants, reduces the negative impact on the environment, prevents damage to the aquatic ecosystem, reduces environmental pollution, protects the ecological environment, and realizes the resource utilization of wastewater.

[0003] Currently, wastewater treatment devices used in black pig farms generally require cleaning of the screens with high-pressure water guns after a period of use. However, considering that excessive pressure from the water guns can cause residual material on the screen surface to scatter, these solid particles may deviate from the intended collection path, causing pollution to the surrounding environment. This leads to an additional increase in the frequency of manual cleaning and may also pose a safety hazard of accidental injury. Therefore, a wastewater treatment device for black pig farms is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment device for black pig farms, in order to solve the problem mentioned in the background art that the impurities ejected during the regular cleaning of existing wastewater treatment devices for black pig farms will cause pollution to the surrounding environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wastewater treatment device for black pig farms includes a separating tank. An inclined screen body is fixedly installed on the front slope of the separating tank. Side clamping frames are fixedly connected to both sides of the separating tank. A limiting sleeve is fixedly connected to the middle groove of the side clamping frame. A hydraulic telescopic rod is fixedly installed inside the limiting sleeve. A slider is fixedly connected to the movable end of the hydraulic telescopic rod. A side baffle is fixedly connected to the side of the slider near the separating tank. Inclined chutes are provided on both sides of the front slope of the separating tank. An inclined scraper that fits against the side baffle is fixedly connected to the front end of the inclined chutes. Side guard plates are fixedly connected to the opposite sides of the two inclined scrapers. A square opening is provided on the surface of the inclined scraper facing the inlet of the inclined chutes. A stop block is fixedly connected to the front end of the inclined scraper.

[0007] Preferably, a drain pipe is connected to the lower rear end of the separating water tank, and a conveying box is connected to the upper rear end of the separating water tank.

[0008] Preferably, a slag discharge box is connected to the left side of the separation tank, the outlet end of the slag discharge box is set to the left, and a screw drive motor is fixedly installed on the right side of the separation tank, the output end of the screw drive motor extends to the inside of the separation tank.

[0009] Preferably, a bracket is provided at the front of the inclined screen body. The bracket has a "U" shaped structure. The vertical end of the bracket is fixedly connected to the separation water tank, and a vibrator is fixedly installed at the middle of the horizontal end of the bracket.

[0010] Preferably, both the left and right side baffles are slidably connected to the two side clip frames. The side clip frames are connected by a sliding groove and a slider groove provided in the middle position. The side baffles and side guards are arranged in parallel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the side frame, limiting sleeve, hydraulic telescopic rod, slider, and side baffle facilitate the use of the wastewater treatment device for black pig farms. During the periodic cleaning of impurities adhering to the inclined screen body using a high-pressure water gun, the side protection structure, composed of the side frame, limiting sleeve, hydraulic telescopic rod, slider, and side baffle, is first extended to provide side protection against impurities ejected during water gun cleaning.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A wastewater treatment device for black pig farms includes a separating tank 1. An inclined screen body 3 is fixedly installed on the front slope of the separating tank 1. Side clamping frames 4 are fixedly connected to both sides of the separating tank 1. A limiting sleeve 5 is fixedly connected in the middle groove of the side clamping frame 4. A hydraulic telescopic rod 6 is fixedly installed on the inner side of the limiting sleeve 5. A slider 7 is fixedly connected to the movable end of the hydraulic telescopic rod 6. A side baffle 8 is fixedly connected to the side of the slider 7 near the separating tank 1. Inclined chutes 9 are provided on both sides of the front slope of the separating tank 1. An inclined scraper 10 that fits against the side baffle 8 is fixedly connected to the front end of the inclined chutes 9. Side guard plates 12 are fixedly connected to the opposite sides of the two inclined scrapers 10. A square opening 11 is opened on the surface of the inclined scraper 10 facing the inlet of the inclined chutes 9. A stop block 13 is fixedly connected to the front end of the inclined scraper 10.

[0021] like Figure 1 and Figure 2As shown, a drain pipe 16 is connected to the lower rear end of the separation tank 1, and a conveying box 2 is connected to the upper rear end of the separation tank 1. The arrangement of the conveying box 2 and the drain pipe 16 facilitates the connection of the device to the wastewater pumping pipeline and the treatment pipeline of the next stage treatment equipment. A slag discharge box 14 is connected to the left side of the separation tank 1, with the outlet end of the slag discharge box 14 facing left. A screw drive motor 15 is fixedly installed on the right side of the separation tank 1, and the output end of the screw drive motor 15 extends to the inside of the separation tank 1. The device is designed to spiral the separated impurities to the left, carrying them into the interior of the device. A bracket 17 is provided at the front of the inclined screen body 3. The bracket 17 has a "U" shaped structure. The vertical end of the bracket 17 is fixedly connected to the separation water tank 1. A vibrator 18 is fixedly installed at the middle of the horizontal end of the bracket 17. When solid-liquid separation is performed through the inclined screen body 3, the vibration force generated by the vibrator 18 will be transmitted to the inclined screen body 3 to improve the filtration efficiency of the inclined screen body 3.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both left and right side baffles 8 are slidably connected to two side clip frames 4. The side clip frames 4 are connected to the slider 7 through a groove provided in the middle position. The side baffles 8 and the side guard plate 12 are arranged in parallel. The connection between the side guard plate 12 and the inclined scraper 10 forms an "L" shaped structure. There are two sets of baffles 13, with each set consisting of two blocks. The gap between the front and rear baffles 13 is equal to the width of the side baffles 8. When scraping, the front and rear baffles 13 are mainly used to limit the scraped impurities to a certain range and prevent them from sliding down directly.

[0023] Workflow: The electrical energy required for the device to start and operate in this utility model comes from the power module in the wastewater treatment workshop of the farm. Before using the device, the inlet of the conveying box 2 needs to be connected to the wastewater pumping pipeline, and the drain pipe 16 needs to be connected to the treatment pipeline of the next stage treatment equipment. During the feeding of black pigs in the farm, when it is necessary to treat the farm wastewater generated regularly, the wastewater containing impurities is first pumped from bottom to top into the conveying box 2 through the wastewater pumping pipeline. When it is full to a certain level, the wastewater containing impurities will overflow into the separation chamber and slide down the inclined screen body 3. At this time, With the auxiliary connection of bracket 17, as the vibrator 18 in the start-up state transmits vibration force to the inclined screen body 3, the device will use the inclined screen body 3 to effectively separate solids and liquids in the wastewater. The separated liquid will fall into the interior of the separation tank 1 and then be discharged outward through the drain pipe 16. The separated solid impurities will slide into the spiral conveying area at the front end of the separation tank 1. Finally, the spiral drive motor 15 is started to rotate the spiral auger assembly at the front end of the separation tank 1, conveying the impurities into the slag discharge box 14 for further separation. The impurities will push open the left side of the slag discharge box 14. The side outlet cover plate then pulls the impurities outward, completing the entire processing. When it's necessary to periodically clean impurities adhering to the inclined screen body 3, firstly, under the connection of the limiting sleeve 5, the hydraulic telescopic rod 6 is driven to tilt and push the slider 7 forward. The side baffle 8 will then be pulled outward from inside the side frame 4, tightly fitting the inclined scraper 10. Once stretched to the desired position, the left and right side baffles 8 will act as side shields from the left and right sides of the separation tank 1 during the high-pressure water gun cleaning of the inclined screen body 3, preventing excessive impurities from being directly ejected and carried out of the entire device. After the entire cleaning work is completed, the hydraulic telescopic rod 6 is restarted to reset and stretch, and the side baffle 8 begins to reset. In a state of tight fit, as the side baffle 8 gradually retracts into the inside of the side frame 4, the inclined scraper 10 scrapes off the impurities adhering to the protective surface of the side baffle 8, preventing the impurities from being brought into the interior of the side frame 4. Finally, after the stretching and scraping work is completed, the scraped impurities can be manually pushed into the interior of the square opening 11, so that they pass through the interior of the square opening 11 and fall into the interior of the inclined chute 9, and slide at an angle into the spiral conveying area at the front end of the separator tank 1. The cleaning work of the entire side baffle 8 is then completed.
