A first mounting seat is provided on the top surface of the stirring chamber. A first servo motor is fixed downward on the first mounting seat. A second mounting seat is fixedly installed above the partition.

[0004] However, it was found during the use of the device that it was not convenient to separate the liquid from the sewage, which reduced the effectiveness of using more suitable and efficient treatment methods for the different properties of solids and liquids. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a harmless treatment device for pig manure, which improves the uniformity of manure and facilitates the mixing of manure and bacteria, thereby improving the quality of subsequent composting and fermentation and increasing resource utilization efficiency.

[0006] This utility model discloses a harmless treatment device for pig manure, comprising a tank and a discharge valve connected to the bottom of the tank; it also includes a separation component, a stirring component, a separation box, a feed hopper, a drain pipe, and a conveying channel. The separation box is installed at the top of the tank, the feed hopper is connected to the top of the separation box, the drain pipe is connected to the lower part of the outer wall of the separation box, and the conveying channel is connected between the separation box and the tank. The separation component is installed inside the separation box to separate the solid and liquid components of the manure. The stirring component is installed inside the tank to mix the manure. The manure is fed into the separation box through the feed hopper, and the manure inside the separation box undergoes solid-liquid separation through the separation component. The separated liquid is discharged out through the drain pipe, and the separated solid and liquid are conveyed to the tank through the conveying channel. By using the stirring component to mix the manure in the tank, the uniformity of the manure is improved, and it is also easier to mix the manure with microorganisms, thereby improving the quality of subsequent composting and fermentation and increasing resource utilization efficiency.

[0007] Preferably, the separation assembly includes a first rotating roller, a filter cloth, a second rotating roller, a belt, support rollers, and a second motor. Multiple sets of first rotating rollers are rotatably installed inside the separation chamber, and the filter cloth is fitted over the outside of the multiple sets of first rotating rollers. Two sets of second rotating rollers are rotatably installed on the inner sidewall of the separation chamber. A belt is fitted over the two sets of second rotating rollers, with a gap between the belt and the filter cloth. Multiple sets of support rollers are rotatably installed on the inner sidewall of the separation chamber, and the multiple sets of support rollers are in contact with the belt. Two sets of second motors are installed on the outer sidewall of the tank, and the output ends of the two sets of second motors are respectively connected to the first rotating roller and... The second roller is connected; the sewage falls onto the filter cloth through the feed hopper, and the first roller is rotated by the second motor. Multiple sets of first rollers work together to move the filter cloth circumferentially, so that the filter cloth conveys the sewage toward the gap. At the same time, the second roller is rotated by the second motor, so that the second roller drives the belt to move circumferentially. The belt works with the filter cloth to squeeze and dewater the sewage. The liquid in the sewage passes through the filter cloth and falls to the bottom of the separation box and is discharged through the drain pipe. The dewatered sewage is discharged into the tank through the conveying channel, which improves the convenience of continuous solid-liquid separation of sewage.

The first motor is installed at the top of the tank, and the support shaft is rotatably installed inside the tank. The output end of the first motor is connected to the support shaft. The mixing blades and spiral blades are respectively installed on the outer wall of the support shaft. The first motor drives the support shaft to rotate, causing the support shaft to move the mixing blades circumferentially to mix and stir the manure in the tank. At the same time, when the support shaft rotates in the forward direction, the spiral blades lift and transport the manure in the tank upward, improving the uniformity of mixing and stirring of the manure and improving the quality of subsequent processing of the manure. When the support shaft rotates in the reverse direction, the discharge valve is opened, which facilitates the rapid discharge of the manure in the tank.

[0009] Preferably, it also includes a feed pipe, which is connected to the upper part of the outer wall of the tank; the feed pipe facilitates the addition of bacteria into the tank and mixing with the feces.

[0010] Preferably, it also includes a flow guide platform, which is located at the bottom of the separation tank; the flow guide platform guides and transports the liquid, improving the smoothness of liquid discharge.

[0011] Preferably, it also includes a scraper plate, which is installed on the inner side wall of the separation box and contacts the belt and filter cloth; after the filter cloth and belt rotate, the scraper plate scrapes and cleans their surfaces, reducing the adhesion of fecal matter.

[0012] Preferably, the gap between the filter cloth and the belt gradually narrows, thereby improving the effect of gradually compressing the fecal matter.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the manure is put into the separation box through the feed hopper, and the manure entering the separation box is separated into solid and liquid by the separation component. The separated liquid is discharged out through the drain pipe, and the separated solid and liquid are transported to the tank through the conveying channel. The manure in the tank is mixed and stirred by the stirring component, thereby improving the uniformity of the manure and facilitating the mixing of manure with bacteria, improving the quality of composting and fermentation in the later stage, and improving the utilization efficiency of resources.
