Embodiment 1

[0029] The staggered dispersing screw barrel pair of the sorting pulping device is an embodiment of the present invention. In the dispersion pulping screw ( Figure 4 ) staggered spiral dispersing section, outer drum with screen drum ( Figure 5 ), fluctuation ring ( Figure 6 ) and the hydraulic adjustment mechanism to realize the separation and treatment of organic waste.

[0030] Figure 4Pulping auger for sorting. The method of welding the spiral blade and the mandrel is adopted. According to the function, it is divided into three areas: 1. Interlaced and dispersed spiral section; 2. Variable-diameter screw extrusion section; 3. Equal-diameter spiral conveying section. The total length of the spiral from the sorting feed inlet to 1 / 3-1 / 2 from the feed inlet is a staggered dispersing helical section, and the staggered dispersing helical section is two helical blades with a pitch of S arranged alternately, and the helical blades have apertures of For 8MM sieve holes, t...

Embodiment 2

[0036] Figure 7 is an embodiment of the present invention. The variable-diameter screw extrusion section conveys the material from the equal-diameter screw conveying section into the screw groove. The screw blade of the variable-diameter screw extrusion section has a sieve hole with a diameter of 8MM, and the depth of the screw groove of the screw blade decreases evenly. On a conical surface, the maximum depth of the screw groove is the same as the depth of the screw groove of the dispersion pulping spiral, and the minimum depth of the screw groove is the same as the depth of the screw groove of the equal-diameter spiral conveying section. The variable-diameter helical section accounts for between 1 / 5 and 1 / 3 of the length of the entire sorting helix, and the depth of the screw groove at the end of the variable-diameter helical section is 55%-65% of the depth of the initial screw groove.

[0037] In the variable-diameter spiral section, under the joint action of the variable...

Embodiment 3

[0041] Figure 9 is an embodiment of the present invention. The connection structure between the mixing and crushing device (I) and the sorting and pulping device (II) is Figure 9 . The discharge cylinder (7) of the mixing and crushing device (I) is inserted into the feed cylinder (18) of the sorting and pulping device (II). ) between the feeding cylinders (18) form a groove cavity, and the fine particles in the garbage enter the inside of the groove during operation to form a self-sealing and reduce the leakage of liquid during operation.

[0042] The end of the discharge cylinder (7) of the mixing and crushing device (I) is welded with an inner cone ring (8), which forms a spiral pair with the variable-diameter spiral section of the mixing and crushing screw (6) at this position, and the spiral pair of this section increases during operation. The conveying pressure can avoid garbage backflow caused by the sorting and pulping screw (13) of the sorting and pulping device (...

Abstract

The invention discloses a sorting treatment device for urban organic waste. The sorting treatment device comprises a sorting motor, a coupling, an intermittent varied-diameter screw, fluctuation rings, an outer roller, a conical-segment cylinder, a hydraulic supporting and adjusting mechanism, a water injection pipeline, a mixing and crushing device and an automatic control system, wherein the organic waste is mixed and crushed by the mixing and crushing device and conveyed into a sorting and pulping device; a sorting screw and the outer roller provided with screen holes act jointly to sort and pulp the waste; an extrusion screw segment at the conical-segment cylinder and the conical-segment cylinder act jointly to realize forced pressure buildup, slurry in the organic waste is extruded, and the relative distance between the conical-segment cylinder and the screw is adjusted automatically according to pressure formed inside on the basis of different waste components; the slurry passing through filter holes flows into a slurry storage tank through a slurry outlet. The components of the urban organic waste have larger differences, under joint action of the hydraulic supporting and adjusting mechanism, a friction wheel and a sliding bearing, the working angle of the sorting and pulping device is adjusted, a better sorting effect can be realized, and the device is applicable to the waste containing different components.

Description

technical field [0001] The invention relates to crushing, sorting, pulping and other operations on urban organic wastes containing organic matter, so as to separate the organic wastes with utilization value. At the same time, it involves anaerobic fermentation pretreatment of food waste. Background technique [0002] The composition of urban organic waste is complex and changes with changes in region, time, and environment. In addition to plastic products, fabrics, paper products, glass, metal, and wood products, such as kitchen waste and kitchen waste have high utilization rates. The valuable organic waste also occupies a relatively high proportion, and the sorting and treatment of organic waste can realize the resource utilization of organic waste. Because organic matter is mixed with other organic wastes such as plastic bags, textiles, paper products, etc., the current sorting equipment has a single structure and cannot achieve effective separation of organic matter. A ...
