Description

Technical Field

[0001] This utility model relates to the field of fecal waste treatment technology, specifically a solid-liquid separation device for fecal waste treatment. Background Technology

[0002] The livestock and poultry farming industry produces a large amount of manure every day. If this manure is not effectively treated to render it harmless, it will cause great pollution to the environment. The current treatment method is to concentrate the manure and convert it into organic fertilizer. In the initial stage of treatment, solid-liquid separation of the manure is essential. Current technology usually uses a screw extruder for solid-liquid separation of manure. However, during the operation of the screw extruder, its filter screen is easily clogged by solidified manure, which prevents the liquid from being discharged smoothly.

[0003] CN210134010U discloses a solid-liquid separation device for treating livestock manure wastewater, including a shell, a drain mechanism at the bottom of the shell, a conveying pipe and a feed sleeve horizontally fixed at both ends of the shell, a feed pipe horizontally connected to the end of the feed sleeve away from the conveying pipe, a slag discharge mechanism inside the conveying pipe, a separation mechanism between the conveying pipe and the feed sleeve, and an exhaust mechanism at the top end of the shell.

[0004] The existing solid-liquid separation devices for livestock manure wastewater treatment have the following disadvantages: During the use of the existing devices, the spiral structure is not conducive to the discharge of manure from the inside of the separation cylinder, and manure is prone to accumulate again in the separation cylinder, which affects the solid-liquid separation effect of the manure.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0017] Furthermore, the manure scraping structure includes a movable trough, which is located on the top side of the solid manure collection box. A scraper plate is movable inside the movable trough, and a support spring is fixedly connected between the bottom of the scraper plate and the bottom of the movable trough. The side of the scraper plate near the solid manure collection box has a sloping structure.

[0018] Furthermore, the material conveying structure includes a rotating shaft and a second motor. One end of the rotating shaft is rotatably connected to the inner wall of one end of the separation box, and the second motor is fixedly connected to the outer end of the separation box.

[0019] Furthermore, the flushing structure includes a water supply pipe and a fixing plate. The fixing plate is fixedly connected to both ends of the top of the separation tank. The water supply pipe is located above the separation tank, with one end fixedly connected to the fixing plate and the other end inserted through the fixing plate and connected to the water source. Several flushing pipes are evenly distributed at the bottom of the water supply pipe. The bottom of the flushing pipe extends into the interior of the separation tank and is located above the filter cylinder.

[0020] The advantages of this invention compared to existing technologies are as follows: the filter cylinder is periodically rinsed by the flushing structure, and the fecal matter adhering to the inner wall is scraped off by the fecal scraping structure, which solves the problem of easy clogging of the filter screen in existing devices. The solid feces are pushed by the material conveying structure, which avoids the problem of fecal accumulation in existing devices and improves the separation efficiency. Attached Figure Description

Several material-carrying plates 5 are uniformly welded to the inner wall of the filter cylinder 3. A solid fecal collection box 6 is provided inside the filter cylinder 3. Its two ends are welded to the inner wall of the separation box 1. The bottom is an arc-shaped structure adapted to the filter cylinder 3 and has several uniformly opened filter holes 7. One end of the solid fecal collection box 6 extends out of the separation box 1 to form a discharge port 8. A scraping structure 9 is provided on one side of the top of the solid fecal collection box 6, and a conveying structure 10 is provided inside. A flushing structure 11 is provided on the top of the separation box 1. An inlet pipe 12 is connected to the center of the end of the separation box 1 away from the drive structure 4, and a discharge pipe 13 with a control valve 14 is connected to the bottom.

[0030] like Figure 4 As shown, the drive structure 4 includes a gear ring 402 fixedly sleeved on the outer wall of one end of the filter cylinder 3. A drive gear 403 is meshed on one side of the gear ring 402. The drive gear 403 is driven by a motor 404 fixed outside the separation box 1. An installation box 401 is sleeved on the outside of the gear ring 402 and the drive gear 403.
