Abstract

The invention discloses a spiral extrusion type excrement solid-liquid separation device capable of controlling the solid humidity, and relates to an excrement solid-liquid separation device. The device aims at solving the problems that an existing excrement solid-liquid separation device is high in maintenance cost and long in separation time, separated-out solid is high in moisture content, accordingly, the microorganism reaction environment cannot be effectively controlled, and a screen net type solid-liquid separation device is likely to be blocked. The device is composed of a motor, a separator shell, a screen drum, a packing auger and a discharge outlet compression cover. A packing auger shaft of the packing auger is provided with multiple spiral blades. The thread distance of each spiral blade is gradually reduced from the side of the closed end of the separator shell to the side of a conical opening of the separator shell. The screen drum is composed of multiple wedge-shaped strip plates distributed at equal intervals. The inner wall of the screen drum is provided with multiple blocking teeth. The device is stable in operation, solves the problem that blockage is likely to be caused, can control the humidity of solid waste, can meet the requirements of fungi for living environment to enable fungi to be in the optimal fungus living and growth conditions, and is applicable to excrement solid-liquid separation.

Description

technical field

[0001] The invention relates to a stool solid-liquid separation device. Background technique

[0002] Human feces contain a large amount of organic substances, which are biological resources that can be recycled through biodegradation. If they are not utilized and discharged directly, it will cause a great waste of resources; in addition, feces contain a large number of pathogenic bacteria, heavy metals and other Hazardous substances must therefore be disposed of effectively. The ecological toilet is an environmentally friendly toilet that uses microorganisms to convert human excrement into organic fertilizers or soil improvers, which solves the problems of fecal pollution and organic matter enrichment. However, the existing ecological toilets generally use feces-urine integrated reactors. Because the moisture content of the reactor feed cannot be effectively controlled, the humidity of the microbial growth environment is difficult to control, the growth con...

Examples

specific Embodiment approach 1

[0019] Specific implementation mode one: combine Figure 1~3 Describe this embodiment, the screw extrusion solid-liquid separation device of controllable solid humidity in this embodiment, the device consists of a motor 1, a separator housing 2, a screen cylinder 3, an auger 4 and a discharge port compression cover 5 constitute;

[0020] The screen cylinder 3 is composed of a plurality of equidistant strip plates 32. The cross section of the strip plate 32 is wedge-shaped, and the longer side of the wedge is set toward the center of the screen cylinder 3. Several blocking materials are arranged on the inner wall of the screen cylinder 3. tooth 31;

[0021] The separator housing 2 is cylindrical, one end of the separator housing 2 is a closed end, the other end of the separator housing 2 is provided with a tapered opening 21, and the outer circumference of the separator housing 2 is close to the separator. The closed end of the shell 2 is provided with a material inlet 22, an...

specific Embodiment approach 2

[0028] Embodiment 2: The difference between this embodiment and Embodiment 1 is that four screw rods 52 are arranged on the side of the compression cover limiting disc 51 close to the tapered opening 21 . Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0029]Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that four cylinders 54 with vertical bottoms are arranged on the larger bottom surface of the compression cover 5 of the discharge port. Other steps and parameters are the same as those in Embodiment 1 or 2.
