Description

Technical Field

[0001] The utility model relates to the technical field of livestock and poultry waste treatment equipment, in particular to a sewage discharge device for a pig farm. Background Art

[0002] Pig farm sewage treatment systems separate solid waste from the liquid components of feces and urine. Mechanical separation equipment effectively removes solid particles, reducing the burden on subsequent treatment. Solid-liquid separation not only improves wastewater treatment efficiency but also converts solid waste into valuable organic fertilizer, enabling resource recycling and reducing environmental pollution.

[0003] Nowadays, some pig farms’ sewage discharge devices use static filtration. However, static filtration has no power drive and cannot actively push solid waste to move, causing waste to accumulate around the filter holes.

[0004] Accumulated waste will clog the filter holes, which will increase system resistance and make the liquid flow poor, thus affecting the overall filtration efficiency, causing the equipment to operate poorly or even malfunction. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a pig farm sewage discharge device to solve the problems raised in the above background technology.

[0009] As a preferred embodiment, the power mechanism includes a motor, which is fixedly mounted on the bottom of the rotating shaft. The bottom of the motor is fixedly connected to a support plate 1, and the support plate 1 is fixedly connected to the bottom of the tank body. The motor can provide power for the rotation of the rotating shaft.

[0010] As a preferred embodiment, the slag discharge mechanism includes a slag discharge pipe, the bottom of which is fixedly connected to a second conical bucket, the slag discharge pipe is fixedly connected to the bottom of the expanded container near the slag discharge port, and the slag discharge pipe is very short. The conical design of the second conical bucket can reduce the blockage of the discharge port and improve the continuous operation capability of the equipment to a certain extent.

[0011] As a preferred embodiment, a sewage pipe is fixedly connected to the outer surface of the tank body, and the sewage pipe can discharge the liquid inside the tank body.

[0012] As a preferred embodiment, the spiral plate is slightly inclined, with a higher center and lower sides. The spiral plate fits against the top of the partition.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] The utility model utilizes a motor to drive the spiral plate to rotate to achieve dynamic filtration. The rotation of the spiral plate can continuously update the filter area in contact with the waste, reducing the situation where a certain area is blocked for a long time, thereby reducing the possibility of blockage to a certain extent. At the same time, the spiral plate fits with the top of the partition, and the spiral plate can clean the waste on the top of the partition, providing a certain degree of cleaning for the partition, and reducing the blockage of the filter port on the partition to a certain extent, thereby ensuring the flow of liquid, ensuring the efficiency of solid-liquid separation and the stable operation of the equipment.

The feeding pipe 12 can replenish the waste in the first conical bucket 13 into the tank body 1 to achieve continuous feeding.

[0025] like Figure 1-3As shown, the power mechanism includes a motor 17, which is fixedly mounted on the bottom of the rotating shaft 4. The bottom of the motor 17 is fixedly connected to a support plate 18, which is fixedly connected to the bottom of the tank body 1. The motor 17 can provide power for the rotation of the rotating shaft 4, so that the rotating shaft 4 rotates.

[0026] like Figure 1-3 As shown, the slag discharge mechanism includes a slag discharge pipe 10, and a second conical bucket 11 is fixedly connected to the bottom of the slag discharge pipe 10. The slag discharge pipe 10 is fixedly connected to the bottom of the expanded container 2 near the slag discharge port 9, and the slag discharge pipe 10 is very short, which is convenient for clearing the slag discharge pipe 10 when it is blocked.

[0027] like Figure 1-3 As shown, a drain pipe 19 is fixedly connected to the outer surface of the tank body 1, and the drain pipe 19 can discharge the liquid inside the tank body 1 for easy use.

[0028] like Figure 1-3 As shown, the spiral plate 5 is slightly inclined, with the center higher and the surrounding lower. The spiral plate 5 fits against the top of the partition 3. The material of the spiral plate 5 is polytetrafluoroethylene, which has an extremely low friction coefficient and a smooth surface, which helps solid waste to slide down quickly. Combined with the fact that the spiral plate 5 is higher in the middle and lower around, the self-cleaning of the spiral plate 5 is achieved.

[0029] like Figure 1-3 As shown, the support mechanism includes a support plate 15, the bottom of the support plate 15 is fixedly connected to an angle plate 16, the top of the support plate 15 is fixedly connected to two connecting plates 14, the two connecting plates 14 are fixedly connected to the outer surface of the feed pipe 12, the support plate 15 and the angle plate 16 are fixedly connected to the outer surface of the tank body 1, and the angle plate 16 can improve the stability of the support plate 15, thereby ensuring continuous feeding of the equipment.

[0030] Working principle: This equipment is a sewage discharge device for pig farms. When in use, the waste from the pig farm is introduced into the first conical bucket 13. The waste enters the feed pipe 12 through the first conical bucket 13, and then enters the top of the partition 3 inside the tank body 1. The connecting plate 14 can fix the feed pipe 12 on the support plate 2 15, and the angle plate 16 can further improve the stability of the support plate 2 15. The partition 3 cooperates with the filter port 17 to realize the solid-liquid separation of the waste, so that the solid waste stays on the top of the partition 3, and a large amount of liquid will pass through the filter port 7 into the bottom of the tank body 1, and then be discharged from the sewage pipe 19.

[0031] Then start the motor 17 on the support plate 18, and the motor 17 drives the rotating shaft 4 to rotate through the output shaft, and the rotating shaft 4 drives the spiral plate 5 to rotate. The spiral plate 5 can spirally transport a large amount of solid waste upward, and the filter port 2 6 can further separate the liquid in the waste. The material of the spiral plate 5 is polytetrafluoroethylene, which has an extremely low friction coefficient and a smooth surface, which helps the solid waste to slide down quickly. In addition, the spiral plate 5 is high in the middle and low around, so that the spiral plate 5 can be self-cleaned.

[0032] Solid impurities are transported out of the tank body 1 by the spiral plate 5. Since the spiral plate 5 is high in the center and low around, the solid waste will enter the expanded container 2 due to gravity. Then the cleaning block 8 can drive the solid waste into the slag discharge port 9, and then leave the expanded container 2 through the cooperation of the slag discharge pipe 10 and the second conical bucket 11 to achieve solid-liquid separation.
