Problems solved by technology

However, the screw blades on the screw shaft of the existing screw press solid-liquid separator are continuous screw blades, and the maximum performance can only be exerted under suitable feeding conditions and specific working conditions
Continuous spiral forced dehydration has the phenomenon of material slipping and forming "idling", which leads to a decrease in separation performance; and the types of manure treated are limited, and it is not suitable for treating high-viscosity manure. It often requires a large amount of clean water to dilute before operation, resulting in a large amount of sewage. Secondary pollution; the friction force of the slag discharge section is large, the screen wears seriously, the replacement cost is high after the screen wears and fails, the separation efficiency is low, and it is very inconvenient to carry out maintenance in the later period

Embodiment 1

[0039] Embodiment 1: In order to realize the solid-liquid separation treatment of current livestock and poultry manure, improve efficiency, and ensure separation quality, this embodiment provides a solid-liquid separator. Specifically, see Figure 1-9, a solid-liquid separator adapted to various livestock and poultry manure, comprising a frame 1, the frame 1 is a horizontally arranged rectangular frame, the bottom and top of the frame 1 are respectively provided with a rectangular bottom plate and a top plate, The four corners of the bottom plate and the top plate are fixedly connected by longitudinal rods; the middle part of the bottom plate of the frame 1 is longitudinally provided with a trapezoidal support base 18, and the top surface of the support base 18 is horizontally recessed with an arc-shaped groove. The inner shell 22 is placed horizontally, see Figure 7 , both sides of the outer wall of the housing 22 are laterally extended with fixing plates 221, and each fixin...

Embodiment 2

[0046] Embodiment 2: In this embodiment, in order to better realize the solid-liquid separation operation of feces, see Figure 4 , further, the helical blades 28 distributed on the helical shaft 23 adopt a three-stage distribution from front to back, wherein,

[0047] The first section is located below the feed pipe 26. Two first continuous helical blades 283 that are staggered are distributed in the first section. The first continuous helical blades 283 are equal-pitch spirals. The screw pitch is 1.5-2.5 times, providing enough forward thrust to realize the rapid forward transport of dung water, at this time, part of the free water in the dung water is directly discharged through the screen;

[0048] see Figure 4 , Figure 5 , there are 3-6 helical structures with broken teeth distributed in the gap in the second section. The helical structure with broken teeth is a double helix structure formed by two broken tooth blades 282 interlaced. It is staggered in the radial dir...

Embodiment 3

[0050] Embodiment 3: In this embodiment, see image 3 , in order to facilitate the maintenance and replacement of the screen, structurally, the front and rear ends of the first screen 24 are first circular rings arranged in parallel, and a plurality of blocks are axially distributed and fixed on the outer walls of the first circular rings at both ends. The first mounting plate 241, the first screw holes are distributed on the first mounting plate 241; a plurality of annular first reinforcing rings 243 are axially equidistantly distributed in the first ring gap parallel to both sides, each first The first filter plate 242 is annularly distributed on both side walls of the reinforcement ring 243; the snap-fit ​​opening 244 is distributed on the first circular ring at the rear end;

[0051] The front and rear ends of the second screen 36 are second rings arranged in parallel, and the outer walls of the second rings at both ends are axially distributed and fixedly connected with a...

Abstract

The invention discloses a solid-liquid separator suitable for various livestock and poultry feces. The solid-liquid separator comprises a rack, a supporting base is longitudinally arranged on a bottomplate of the rack, and a shell is fixedly connected to the supporting base; a first motor is installed on one side of the bottom in the rack, a spiral shaft is connected to the first motor, the spiral shaft is coaxially located in the shell, and spiral blades are distributed on the spiral shaft; a first screen is arranged at the front end in the shell, and a second screen is arranged at the rearend; opening-closing electric push rods are installed on the two sides of the rear end of the shell, and the mobile ends of the opening-closing electric push rods on the two sides are connected with two opening-closing plates. The two opening and closing plates are hinged to the upper end and the lower end of the inner wall of the rear end opening of the shell, and a gap formed by outward overturning of the two opening and closing plates is a slag outlet. And a pair of excrement suction pumps is arranged on the rack bottom plate in front of the supporting base. The livestock and poultry liquiddung solid-liquid separation efficiency is improved, and the segmented conveying extrusion effect is good.

Description

technical field [0001] The invention relates to the technical field of farming machinery and equipment, in particular to a solid-liquid separator suitable for a variety of livestock and poultry manure and its operating method. Background technique [0002] With the development of breeding enterprises, the country's requirements for environmental protection are becoming more and more stringent; the pollution of the environment by farm sewage and feces has been strengthened; the feces solid-liquid separator is also constantly innovating and pursuing technology, in order to solve more farming manure. water problem. [0003] Solid-liquid separator is the key technology and primary link in the harmless treatment and resource utilization of livestock and poultry manure. Solid-liquid separation can effectively remove nutrients and reduce transportation costs and post-processing difficulties. However, the screw blades on the screw shaft of the existing screw press solid-liquid sepa...
