Embodiment 1

[0035] The equipment of the present invention consists of a feed mechanism, a power mechanism, a screw extrusion mechanism, a solid discharge mechanism, a liquid discharge mechanism and a base 1 (see figure 1 )constitute.

[0036] Such as figure 1 As shown, the feeding mechanism includes a buffer 9 arranged vertically, a feed inlet 11 arranged above the buffer 9 and an overflow outlet 12 arranged on the upper part of the side wall of the buffer 9 . An exhaust pipe 10 is also arranged on the buffer 9 .

[0037] The lower end of the feeding mechanism is connected with the screw extruding mechanism. Such as figure 1 , The screw extrusion mechanism is composed of the main body sleeve 8, the filter screen cylinder 7 arranged in the main body sleeve 8 and the auger 5 arranged in the filter screen cylinder 7. Wherein, the specific structure of filter screen cylinder 7 and auger 5 is as follows:

[0038] ① Auger 5:

[0039] Such as figure 1 As shown, the auger 5 is made of an a...

Embodiment 2

[0049] Utilize the solid-liquid separator of embodiment 1 to carry out the method for solid-liquid separation:

[0050] Turn on the machine, the reduction motor 14 drives the auger 5 to rotate clockwise through the transmission main shaft 13, and then the material to be separated is sent into the buffer 9 through the feed port 11, and the material is transported backward under the action of the rotating auger 5, and is extruded at the same time. pressure. When the material passes through the auger 21 in the front section, the preliminary extrusion is completed, and the extruded water is filtered out through the filter screen cylinder in the front section, and then flows out through the liquid discharge mechanism; the remaining material remains in the screen cylinder 7 and is transported backward to the auger in the rear section. The dragon 22 is further extruded in the auger 22 of the rear section, and the remaining water is filtered out through the filter screen cylinder of t...

Embodiment 3

[0053] In order to further improve the durability of the screw blade 17 of this equipment, the structure of the front section auger screw blade 23 and the rear section auger screw blade 24 can be further improved on the basis of embodiment 1, and its structure is respectively as follows Figure 4 , Figure 5 shown. Such as Figure 4 As shown, the edge of the main structure of the front auger helical blade 23 is a "convex" cross-section, and the covered high wear-resistant rubber strip 18 has a groove that matches the cross-section, so that the entire surface of the helical blade formed in this way is smooth , not easy to fall off during work. The structure of rear section auger screw blade 24 is as Figure 5 As shown, its edge is a special-shaped "convex" cross-section, and the spiral blade formed in this way has higher strength, which meets the requirements of the rear auger for blade strength.

Abstract

The invention discloses a spiral extrusion type solid-liquid separator. The spiral extrusion type solid-liquid separator comprises a feeding mechanism, a power mechanism, a spiral extrusion mechanism, a solid discharging mechanism and a liquid discharging mechanism, wherein the spiral extrusion mechanism comprises a main body sleeve, a filter screen cylinder and a packing auger; the filter screen cylinder is arranged in the main body sleeve, and the packing auger is arranged in the filter screen cylinder; blades of the packing auger are composed of spiral blade bodies and high-wear-resisting rubber coating strips coated on the outer edges of the spiral blade bodies; the packing auger comprises a front section packing auger body and a rear section packing auger body; the filter screen cylinder comprises a front section filter screen cylinder body and a rear section filter screen cylinder body; and the solid discharging mechanism is characterized in that an annular cover plate is arranged at the position of a discharging port of the main body sleeve, and the annular cover plate is connected with a compression spring in an abutting manner. Meanwhile, the invention further discloses a solid-liquid separating method using the spiral extrusion type solid-liquid separator. The spiral extrusion type solid-liquid separator has multiple good effects when being used for conducting solid-liquid separation on feces of beasts and birds, biogas residue and the like.

Description

technical field [0001] The invention relates to a solid-liquid separator, in particular to a screw extruding solid-liquid separation device suitable for solid-liquid separation of methane residue and biogas liquid in pastures, breeding factories and biogas tanks. Background technique [0002] With the development of social economy and the improvement of people's living standards, the proportion of animal food in people's diet structure is getting higher and higher, and the scale of livestock and poultry breeding has also experienced unprecedented development. While the breeding industry is developing, it also brings about the problem of livestock and poultry manure disposal. Due to the high moisture content and foul smell of livestock and poultry manure, it is inconvenient to transport and apply, which also increases the difficulty of reusing livestock and poultry manure, and at the same time brings environmental pollution problems. Moreover, livestock and poultry manure co...
