Description

Technical Field

[0001] This invention relates to the field of waste vegetable processing equipment, and in particular to a comprehensive waste vegetable crushing and processing system that is compatible with biogas engineering. Background Technology

[0002] When harvesting mature fresh vegetables, some inedible parts, such as roots, stems, and incomplete outer leaves, are removed. During transportation, some vegetables are also damaged, so rotten or unsightly leaves must be removed. Before being put on the shelves, some simple processing is also required. Throughout the process, a large amount of residual branches and rotten leaves are generated, forming vegetable waste. These residual leaves are called vegetable scraps, commonly known as rotten vegetable leaves.

[0003] Current methods for treating vegetable waste involve piling it up in fields and letting it decompose to become fertilizer. However, this process occupies land and pollutes the air. After processing, the waste needs to be transferred to storage tanks, which is labor-intensive. Furthermore, the juice from the waste remains inside the vegetables and cannot be extracted for separate use, resulting in resource waste. Improvements are urgently needed. In addition, current anaerobic fermentation technology relies on a limited source of materials, primarily manure and sludge, which severely restricts its development. Summary of the Invention

[0004] The purpose of this invention is to provide a comprehensive waste vegetable crushing and processing system to solve the above-mentioned problems.

[0033] like Figure 1-12 As shown, a full-field waste vegetable crushing and processing system includes a concrete foundation 1 and a feeding hopper assembly 2, a material crushing assembly 3, a material extrusion and conveying assembly 4, and a material pumping assembly 5 disposed in the internal space of the concrete foundation 1.

[0034] The top of the concrete foundation 1 is provided with a feed inlet. An electric stainless steel cover plate 7 is provided on the outside of the feed inlet at the top of the concrete foundation 1. One end of the electric stainless steel cover plate 7 is hinged to the feed inlet at the top of the concrete foundation 1. The bottom surface of the electric stainless steel cover plate 7 is hinged to the push rod end of the electric push rod. The other end of the electric push rod is connected to the inner wall of the feed inlet at the top of the concrete foundation 1 through a hinge.

[0035] Two symmetrically arranged blocking walls 8 are provided on the outer side of the top feed inlet of the concrete foundation 1. The bottom of the blocking walls 8 is fixed to the top surface of the concrete foundation 1 to ensure that as much waste material as possible enters the feed hopper. A control system for controlling the feed hopper assembly 2, the material crushing assembly 3, the material extrusion and conveying assembly 4, and the material pumping assembly 5 is installed on the blocking walls 8. The control system is prior art and is not within the scope of protection of this application.

Both the output end of the geared motor 203 and the end of the stirring shaft 202 are connected to sprockets. The geared motors 203 and the sprockets on the stirring shafts 202 in the same group are connected by chains. The geared motors 203 prevent waste vegetables from accumulating inside the feeding hopper, thus affecting processing efficiency. The bottom of the feeding hopper 201 is connected to a feeding screw cylinder 204. A feeding auger 205 is rotatably connected inside the feeding screw cylinder 204. The feeding auger 205 is controlled to rotate by a reduction motor 206 mounted on the feeding screw cylinder 204. A discharge port is provided at the bottom end of the feeding screw cylinder 204, which is positioned above the inlet of the material crushing assembly 3. In use, waste vegetables are fed into the feeding hopper 201. The rotating stirring shaft 202 and the serrated spiral blades connected to the stirring shaft 202 drive the waste vegetables into the feeding screw cylinder 204. The serrated spiral blades perform preliminary crushing of the waste vegetables. The waste vegetables falling into the feeding screw cylinder 204 are then fed into the material crushing assembly 3 from the discharge port by the feeding auger 205.

[0039] An observation mirror 207 is provided on one side of the discharge port of the feed screw cylinder 204, through which the material discharge from the feed screw cylinder 204 can be directly observed.

The other end of the transition connecting pipe 404 is connected to the discharge port of the crusher 301. A discharge port is provided at the bottom of the cylinder of the screw extrusion conveyor 401, and the discharge port of the cylinder of the screw extrusion conveyor 401 is connected to the feed inlet of the material pumping assembly 5. The top of the cylinder of the screw extrusion conveyor 401 is equipped with a spiral observation mirror 405, through which the material discharge status of the screw extrusion conveyor 401 can be directly observed. In use, the material is conveyed and rolled by the extrusion auger inside the screw extrusion conveyor 401, so that the residual juice in the broken vegetable waste can be squeezed out.

[0042] like Figure 11-12 As shown, the material pumping assembly 5 includes a pump 501 and a pumping support 502. The pump 501 is mounted on the pumping support 502, and the pumping support 502 is fixed to the bottom surface inside the concrete foundation 1. The pump 501 is connected to the discharge port of the screw extrusion conveyor 401 through a feed pipe 505. The discharge port of the pump 501 is connected to the discharge pipe 504 through an electric knife valve 503. The other end of the discharge pipe 504 is connected to the CSTR anaerobic digester (the CSTR anaerobic digester is not shown in the figure).

[0043] The operation process of this invention is as follows:

[0044] In use, the electric stainless steel cover plate 7 is opened by the electric push rod 7, and then the equipment is turned on. The leftover vegetables are poured into the feed hopper 201. Driven by the stirring shaft 202, the leftover vegetables fall into the feed screw cylinder 204 and are conveyed into the crusher 301 by the feed auger 205. After being crushed by the crusher 301, the leftover vegetables are conveyed into the screw extrusion conveyor 401 through the transition connecting pipe 404. The crushed leftover vegetables are then sent into the CSTR anaerobic fermentation tank by the material pumping component 5.
