Description
Technical Field
[0001] The utility model relates to the technical field of straw gasification furnaces, in particular to a crop straw gasification furnace. Background Art
[0002] Straw burning is a traditional way of dealing with agricultural waste, but due to its negative impact on the environment, health and safety, this practice has been generally banned in modern society. Currently, gasifiers are commonly used to burn straw, which is converted into renewable gas through combustion, thereby improving the utilization rate of straw and protecting the air environment.
[0003] The current way of using gasifiers is often to manually dry the harvested straw and then put it into the gasifier for combustion. However, the straw often needs to be crushed into particles in advance. The granular straw enters the gasifier to ensure more complete combustion. When the straw is directly put into the gasifier without being dried in the sun, the large amount of moisture in the straw is not conducive to the complete combustion of the crop straw, and the efficiency of converting it into gas is also greatly reduced.
[0004] Therefore, the utility model provides a crop straw gasifier to solve the above problems. Summary of the Invention

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] like Figure 1-5 As shown,
[0022] Example 1:
[0023] The crop straw gasification furnace comprises a furnace body 1, a feeding port 101 is provided on the top of the furnace body 1, and a drying and shearing component 2 is provided on one side of the furnace body 1;
[0024] The drying and shearing assembly 2 includes a drying box 201 arranged on one side of the furnace body 1, and the side wall of the drying box 201 is fixedly connected with a slide 202 for straw to slide into the box, and the drying box 201 is provided with a corresponding slot on one side of the slide 202, and the side wall of the drying box 201 is fixedly connected with a shearing frame 203, the shearing frame 203 is connected to the slide 202, one side of the shearing frame 203 is fixedly connected to the cylinder 204, the output end of the cylinder 204 is fixedly sleeved with a shearing knife 205, the side of the shearing frame 203 away from the shearing knife 205 is fixedly connected with a block seat 206, and a base 207 is provided on one side of the drying box 201, the top of the base 207 is fixedly connected with a drive motor 208, and the output end of the drive motor 208 is fixedly sleeved with a stirring roller 209.
[0025] A suction machine 102 is fixedly connected to the top of the furnace body 1, and a feed pipe 103 for conveying straw is fixedly connected to the output end of the suction machine 102. The other end of the feed pipe 103 is connected to the top of the drying box 201. A control switch 104 is fixedly connected to the outer wall of the suction machine 102. A PLC controller 105 is provided on the top of the furnace body 1, and the control switch 104 is electrically connected to the PLC controller 105.
[0026] A humidity detector 210 for detecting the humidity of the straw is fixedly mounted on the top of the drying box 201, and the detection end of the humidity detector 210 extends into the interior of the drying box 201. The control end of the humidity detector 210 is connected to the PLC controller 105 through a data transmission line to realize data transmission. A feeding component 3 is provided on one side of the drying box 201.
[0027] Specifically, fuel can be placed through the feed port 101 to facilitate combustion in the gasifier. The drying box 201 in the drying and shearing assembly 2 can dry the straw, dry the moisture inside the straw, and improve the combustion efficiency in the gasifier. When the straw passes through the slide 202 and enters the shearing frame 203, the straw is sheared by the shearing knife 205 connected to the output end of the cylinder 204. The opposite serrated block 206 can provide a barrier for the shearing of the straw, which is more conducive to the straw being cut into particles. When the granular straw enters the drying box 201, the moisture inside the straw is reduced by the high temperature baking inside the drying box 201, and then the driving motor is used to drive the straw. The stirring roller 209 at the output end 208 continuously rolls the straw, and the continuous rolling can expand the drying area of the granular straw. When the humidity of the straw meets the set humidity, the humidity detector 210 transmits the data signal to the PLC controller 105, and then the PLC controller 105 controls the control switch 104 of the suction machine 102. When the control switch 104 of the suction machine 102 is turned on, the granular straw is sucked into the furnace body 1 by the suction machine 102 for combustion. The combustion of the straw is accelerated by cutting and drying, which can improve the combustion efficiency of the straw, make the straw burn more cleanly, and avoid the residual straw from causing blockage and damage in the furnace.
[0028] Example 2:
[0029] Based on Example 1:
[0030] The feeding assembly 3 includes a support plate 301 arranged on one side of the furnace body 1, and a plurality of support columns 302 for providing stability are fixedly connected at the four corners of the lower bottom end of the support plate 301. A support frame 303 is fixedly connected to the top end of the support plate 301. A transmission roller 304 is rotatably connected to the inner wall of the support frame 303, and a conveyor belt 305 for conveying materials is rotatably sleeved on the outer wall of the transmission roller 304.
[0031] The outer wall of the conveyor belt 305 is provided with multiple placement components 4, and the placement component 4 includes a connecting block 401 fixedly connected to the outer wall of the conveyor belt 305, the top of the connecting block 401 is fixedly connected to a limiting plate 402, the four corners of the top of the limiting plate 402 are fixedly connected to a slide 403, and the top of the limiting plate 402 is located inside the slide 403 and is fixedly connected to a telescopic spring 404.
[0032] The side wall of the slide 403 is rotatably connected to a rotating rod 405, the outer wall of the rotating rod 405 is fixedly connected to a fixing clamp 406, the inner wall of the slide 403 is slidably connected to a placing plate 407, and the placing plate 407 is in contact with the top end of the telescopic spring 404, and the lower bottom end of the placing plate 407 is located at one end of the fixing clamp 406 and is fixedly connected to a protruding rod 408.
[0033] Specifically, the straw bundles are placed on the placement plate 407 by the placement component 4, which replaces the low efficiency of the traditional manual feeding of straw into the gasifier and avoids the safety accident of scalding during manual feeding. When the straw is placed on the placement plate 407, the placement plate 407 slides inside the slide 403 due to its weight, and the protruding rod 408 at the lower end of the placement plate 407 abuts against the lower end of the fixing clamp 406, so that the fixing clamp 406 rotates inward on the rotating rod 405, thereby clamping the straw bundles, ensuring that the straw does not fall off during the horizontal transportation process and the conveyor belt 305 is not blocked. When the conveyor belt 305 transports the placement plate 407 to the slide 202, the straw slides from the fixed clamp 406 into the slide 202 due to its own weight, and then the weight disappears, causing the telescopic spring 404 to slide the placement plate 407 back to its original position in the slide 403. When the straw is in the slide 202, it will be cut into particles by the shearing knife 205 and enter the drying box 201 for drying. This device can greatly improve the feeding efficiency of the straw, save labor, and also improve the combustion efficiency of the straw on a large scale. It should be noted that the suction machine, drying box, PLC controller, and control switch described in the article are all existing technologies, so they will not be described in detail.
[0034] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
