Description

Technical Field

[0001] The utility model relates to a solid-liquid separation device. Background Art

[0002] Most farmers usually use the method of direct water flushing when dealing with feces and urine. However, this method has some significant problems and disadvantages. First, it requires a lot of water resources, which is particularly problematic in areas with tight water resources. Second, this method will cause a large amount of nutrient loss, which not only wastes precious fertilizer resources, but may also pollute the environment.

[0003] Manure treatment is also a major problem in the aquaculture industry. Manure treatment is particularly complicated because it contains high moisture, strong odor and is difficult to transport. Traditional treatment methods often cannot effectively solve these problems, so it is necessary to find more efficient and environmentally friendly solutions.

[0004] In order to overcome these difficulties, farms can take solid-liquid separation measures to pre-treat manure. This technology can not only effectively reduce the volume of manure, but also reduce the risk of loss during transportation. Through solid-liquid separation, we can separate the solid manure from the liquid part. After simple treatment, the solid part can be fermented and eventually converted into organic fertilizer for fertilizing farmland. The liquid part can be fermented with biogas slurry to further extract the beneficial components for returning water and fertilizer to the field.

[0005] With the solid-liquid separation technology, the treatment of manure on the farm becomes easier and more efficient. This not only saves the cost of environmental treatment, but also reduces the land area used, because a large amount of land is no longer needed to pile up or treat untreated manure. In addition, this method also has significant social and economic benefits. The social benefits are reflected in improved environmental sanitation and reduced pollution, while the economic benefits come from the sale and use of organic fertilizers and reduced dependence on chemical fertilizers.

[0006] However, the existing solid-liquid separators in farms have certain limitations in the treatment effect of the manure-water separation process. Although this equipment can effectively separate solid matter from liquid, the moisture content of the separated dry matter is still high. This phenomenon has an adverse effect on the subsequent organic fertilizer composting and fermentation process, because the excessively high moisture content cannot meet the basic conditions for composting and fermentation.

[0028] (Example 1)

[0029] See Figure 1 The solid-liquid separation device of this embodiment includes a frame, on which a driving motor 8 and a separation box 1 are provided, and the separation box 1 is provided with a feed port 2, a liquid discharge port and a solid discharge port 3, the feed port 2 is arranged at the upper part of one end of the separation box 1, and the solid discharge port 3 is arranged at the other end of the separation box 1; a rotating main shaft 4 is arranged inside the separation box 1, and continuous spiral blades 5 are arranged on the rotating main shaft 4; a heating zone 6 is arranged at the tail end of the separation box 1.

[0030] Specifically, the solid-liquid separation device also includes an adjusting device 7, which is arranged at the solid discharge port 3. The adjusting device 7 adjusts the discharge speed of the solid discharge port according to the water content of the material. The adjusting device 7 includes a moisture detection device, an adjusting spring and an adjusting shell. The moisture detection device detects the moisture content of the material at the solid discharge port, and the adjusting spring controls the pressing degree of the adjusting shell on the solid discharge port 3. The heating zone 6 is provided with an electromagnetic induction heating device. The electromagnetic induction heating device heats the material that has been initially separated, and the moisture contained in the material is subjected to secondary heating and separation, thereby further improving the effect of solid-liquid separation.

[0031] The driving motor 8 is arranged at one end of the separation box 1 , and the output shaft of the driving motor 8 is connected to the rotating main shaft 4 through a reducer 9 .

[0032] The liquid discharge port is located on the side wall of the separation box 1, and a liquid collecting device 10 is arranged below the liquid discharge port. In this embodiment, the liquid collecting device 10 is funnel-shaped.

[0033] In this embodiment, the spiral blade 5 is a double spiral blade, which makes the solid-liquid separation effect better.

[0034] The material to be separated enters the separation box 1 from the feed port 2, the driving motor 8 drives the rotating main shaft 4 to rotate, and the spiral blade 5 drives the material to spirally rotate and move forward, and the initial solid-liquid separation is performed at the same time.
