Description

Technical Field

[0001] The utility model relates to the field of biogas production, in particular to a raw material processing device for biogas production. Background Art

[0002] Biogas is a combustible gas produced by the fermentation of organic matter under anaerobic conditions. Since this gas was first discovered in swamps, it is called biogas. Various organic matter such as human and animal feces, straw, sewage, etc. are fermented under anaerobic conditions (without oxygen) in a closed biogas tank, that is, they are decomposed and transformed by a wide variety of biogas fermentation microorganisms to produce biogas.

[0003] Crop straw is the largest byproduct of agricultural production and has a lot of sustainability. Mainly wheat, corn, peanuts, soybeans and other crop straw, these straws are widely found in rural areas, providing sufficient raw material sources for biogas production. Straw has significant advantages and broad development prospects in biogas production.

[0004] The production process of straw biogas mainly includes the steps of raw material processing, fermentation and biogas collection. Among them, raw material processing is the key link to improve the utilization rate of straw and the gas production rate. Through pre-treatment methods such as crushing and wetting, the straw can be made easier to be decomposed by microorganisms, thereby increasing the biogas production. In the relevant straw biogas production technology, the straw is generally processed by crushing the straw with a crusher, and then mixing and composting. However, when this method is used, taking sweet potato straw as an example, when stirring in the crusher, the straw is easily entangled on the crushing roller in the crusher. Not only is it difficult to remove, but when too much straw is wrapped around the crushing roller, it will also affect the crushing effect of the crushing roller, which is not conducive to subsequent mixing and composting.

[0005] Therefore, it is necessary to provide a raw material processing equipment for biogas production to solve the above technical problems. Utility Model Content

[0023] The cutting assembly 2 includes a guardrail 21 disposed on the top of the operating box 1, a placement rack 22 is disposed inside the guardrail 21 and located on the top of the operating box 1, the right side of the inner side of the guardrail 21 is connected to the right side of the top of the operating box 1, and a cutter 23 is disposed inside the placement rack 22 so as to slide up and down;

[0024] By setting the cutting component 2, for some straws that are difficult to crush directly, such as sweet potato and corn straws, the straws can be placed into the protective frame 28 from the left side of the protective fence 21, and then cut into sections in advance by the up and down moving cutter 23, thereby improving the subsequent crushing effect.

[0025] The crushing assembly 3 includes two crushing rollers 31 which are longitudinally rotatable and arranged on the inner wall of the operating box 1. A discharge chamber 32 is arranged below the two crushing rollers 31 and at the bottom of the inner wall of the operating box 1. A guide plate 33 is arranged at the top of the discharge chamber 32 and on the left and right sides of the two crushing rollers 31.

[0026] The straw entering from the top right side of the operating box 1 is crushed by two crushing rollers 31 rotating away from each other.

[0027] A cam 24 is rotatably provided on the inner side of the placement rack 22, a connecting plate 25 is rotatably provided on the bottom of the cam 24, a connecting block 26 is rotatably provided on the bottom of the connecting plate 25, the bottom of the connecting block 26 is fixedly connected to the top of the cutter 23, and a feed roller 27 is rotatably provided on the left side of the inner side of the placement rack 22. The feed roller 27 is located on the left side of the cutter 23, and a lever is provided on the peripheral side of the feed roller 27.

[0028] The rotation of the cam 24 is driven by the rotation of the output end of the first motor 4, which in turn drives the connecting plate 25 to move up and down, and cooperates with the connecting block 26 rotatably connected thereto and the cutter 23 that moves up and down with a limit, so that the cutter 23 can repeatedly move up and down on the inner side of the placement rack 22 to segment the straw; through the setting of the feed roller 27, when the lever contacts the straw, an inward traction force is generated, so that the straw enters the bottom of the cutter 23, and the cut straw will be pushed to the inside of the operating box 1 by the straw that enters again, and since the lever on the feed roller 27 is relatively sparse, the straw will not be entangled.

[0029] The bottom of the left side of the placement rack 22 is connected to a protective frame 28, a material baffle plate 29 is rotatably provided on the left side of the protective frame 28, a first motor 4 is provided on the top of the protective frame 28, and the output end of the front side of the first motor 4 is connected to the front end of the cam 24 and the front end of the feed roller 27 through a belt.

An auger 34 is rotatably disposed laterally on the inner side of the discharge chamber 32 , and a discharge port 35 is disposed on the left side of the bottom of the discharge chamber 32 .

[0031] After the straw is broken, it will fall into the discharge chamber 32 at the bottom, and then the rotation of the output end of the second motor 36 drives the rotation of the auger 34, so that the straw is transported out of the operating box 1, and then it can be carried out to the next step of composting or mixing to produce biogas.

[0032] A second motor 36 is disposed on the left side of the top of the discharge chamber 32 , and an output end on the left side of the second motor 36 is connected to a left end belt of the auger 34 .

[0033] The working principle of a raw material processing equipment for biogas production provided by the utility model is as follows:

[0034] Step 1: When in use, according to the type of straws put in, the easily broken straws are directly put into the top right side of the operation box 1, and for the hard-to-break straws, the straws can be put into the protection frame 28 from the left side of the protection fence 21, and the feed roller 27 is driven to rotate by the rotation of the output end of the first motor 4, and then the feed roller 27 moves the straws to the right side, and at the same time, the cam 24 rotates to drive the connecting plate 25 to move up and down, and cooperates with the connecting block 26 rotatably connected to it and the cutter 23 that moves up and down, so that the cutter 23 can repeatedly move up and down on the inner side of the placement frame 22 to segment the straws, and the cut straws will be pushed into the operation box 1 by the straws that enter again;

[0035] Step 2: The straw entering from the top right side of the operating box 1 is crushed by two crushing rollers 31 rotating away from each other. After being crushed, the straw falls into the discharge chamber 32 at the bottom, and then the rotation of the output end of the second motor 36 drives the rotation of the auger 34, so that the straw is transported out of the operating box 1, and then the next step of composting or mixing is carried out to produce biogas.

[0036] Compared with the related art, the raw material processing equipment for biogas production provided by the utility model has the following beneficial effects:

[0037] The straw is placed into the protective frame 28 from the left side of the protective fence 21, and the rotation of the output end of the first motor 4 drives the feed roller 27 to rotate, and then the feed roller 27 moves the straw to the right. At the same time, the cam 24 rotates to drive the connecting plate 25 to move up and down, and cooperates with the connecting block 26 rotatably connected to it and the cutter 23 that moves up and down, so that the cutter 23 can repeatedly move up and down on the inner side of the placement frame 22 to segment the straw. The structure is simple and practical, which is convenient for early segmentation of straw with poor crushing effect, thereby improving the subsequent mixing and composting effect.
