Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to pig farming sewage treatment equipment. Background Art

[0002] Pork is one of the main meat consumption of residents at this stage, which has led to the rapid development of the pig farming industry. In pig farms, a large amount of sewage containing feces is generated every day. In order to avoid the direct discharge of sewage causing a greater impact on the environment and water sources, it is necessary to treat the sewage through a special sewage treatment device. The existing sewage treatment device mainly treats sewage containing feces by building a sewage treatment pool, and realizes solid-liquid separation through sedimentation. The sediment can be processed and used as waste. In the later stage, the sediment needs to be cleaned and reused regularly, which is more troublesome and requires a lot of manpower and material resources. In addition, the sediment has a high water content, and the later storage and transportation are more troublesome.

[0028] When using the pig wastewater treatment equipment, if Figure 1-Figure 7As shown, the device is powered by an external power supply, and the water inlet 101 is connected to the sewage discharge pipe, and then the liquid guide pipe 103 is connected to the sewage treatment agent box, so as to facilitate the subsequent addition of agents to purify the sewage. When the sewage is treated, the sewage enters the treatment box 1 through the water inlet 101, and cooperates with the sub-screen 2 to achieve solid-liquid separation of the sewage. The solid matter remains on the sub-screen 2, and the sewage is below the sub-screen 2. At this time, the motor 3 is started synchronously, and the agent is transported into the liquid guide pipe 103 through the pump. The agent is sprayed out through the nozzle 104 to contact the sewage, and Under the action of the motor 3, the rotating shaft 301, the stirring plate 302, the disc 303 and the convex shaft 304 can be synchronously driven to rotate.

When the ball 1003 is in contact with the upper inclined surface of the processing box 1, When the second scraper 10 and the guide rod 1001 are touched, the sliding action between the ball 1003 and the upper inclined surface of the treatment box 1 can make the second scraper 10 and the guide rod 1001 slide downward under force, and the sliding action between the second scraper 10 and the fixed plate 9 can clean the solid objects adhered to the surface of the fixed plate 9, so as to ensure the cleanliness of the fixed plate 9 and provide a basic guarantee for the normal operation of the subsequent device. When the ball 1003 moves in the reverse direction and separates from the upper inclined surface of the treatment box 1, the second scraper 10 can be automatically reset under the elastic action of the second spring 1002 to ensure the normal operation of the device.

[0029] A movable plate 6 is arranged in the fixed box 4, a slide bar 601 is fixed on the movable plate 6, the slide bar 601 penetrates the fixed box 4 and is fixed to the connecting plate 701, the slide bar 601 is connected to the fixed box 4 in a sliding manner, a pressing plate 602 is arranged on the side of the movable plate 6, a cross bar 603 is fixed on the side of the pressing plate 602 close to the movable plate 6, the cross bar 603 is connected to the movable plate 6 in a sliding manner, one end of a first spring 604 is also fixed on the side of the pressing plate 602 close to the movable plate 6, and the other end of the first spring 604 is fixed to the first spring 604. One end is fixed on the movable plate 6; a sealing plate 501 is fixed on the output end of the cylinder 5, and the sealing plate 501 contacts the lower end surface of the fixed box 4 to achieve a sealing effect, and the sealing plate 501 contacts the movable plate 6 and the pressure plate 602 to form a sliding mechanism; a movable frame 502 is fixed on the sealing plate 501, and one end of a vertical rod 503 is fixed on the movable frame 502, and the other end of the vertical rod 503 is fixed on the first scraper 504, and the first scraper 504 contacts the fixed box 4 to form a sliding mechanism;

[0030] After the solids enter the fixed box 4, Figure 1-Figure 6As shown, when the slide rod 7 moves, the connecting plate 701 is synchronously driven to move, thereby driving the cross bar 603 and the movable plate 6 to move, and the sliding action between the slide rod 601 and the fixed box 4 can ensure the stability of the movement of the movable plate 6. When the movable plate 6 moves, the pressing plate 602 is synchronously driven to move. When the connecting plate 701 moves to the left, the pressing plate 602 moves to the left synchronously, and the solids on the sub-screen 2 enter the left fixed box 4. The pressing plate 602 in the right fixed box 4 moves to the left to contact the right fixed box 4. When the connecting plate 701 moves to the right, the pressing plate 602 moves to the right synchronously, and the solids on the sub-screen 2 enter the right fixed box 4. The pressing plate 602 in the left fixed box 4 moves to the right to squeeze the solids in the left fixed box 4. When the pressing plate 602 contacts and squeezes the solids in the fixed box 4, the water in the solids can be effectively squeezed out. The squeezed water enters the processing box 1 through the filter screen between the fixed box 4 and the processing box 1 to be processed. In the squeezing process, as the solids in the fixed box 4 increase, , the moving distance of the pressing plate 602 becomes smaller, and the elastic effect of the first spring 604 and the guiding sliding effect between the cross bar 603 and the movable plate 6 can ensure the normal operation of the device, thereby ensuring the extrusion and dehydration of the solids, thereby effectively reducing the volume of the solids and facilitating subsequent processing. When it is necessary to clean the solids in the fixed box 4, it is only necessary to control the cylinder 5 to extend, thereby driving the sealing plate 501, the movable frame 502, the vertical rod 503 and the first scraper 504 to move downward, thereby releasing the sealing effect of the lower end of the fixed box 4, facilitating the discharge of the extruded solids, and when the solids are bonded to the fixed box 4, the first scraper 504 moves downward to contact the solids in block form, which can provide a downward force on the solids and facilitate the discharge of the solids. In addition, in conjunction with the sliding effect between the first scraper 504 and the fixed box 4, the solids bonded to the filter net between the fixed box 4 and the processing box 1 can be scraped off to ensure the cleanliness of the filter net, providing a basic guarantee for the normal operation of the subsequent device. This is the working principle of the pig sewage treatment equipment.
