Description

Technical Field

[0001] This utility model relates to the field of gasifiers, and in particular to a dry slag discharge biomass gasifier. Background Technology

[0002] A biomass gasifier is a device that converts biomass into combustible gas through a gasification process. The gasification process takes place under high temperature and limited oxygen conditions. Biomass is heated and decomposed to produce syngas, which is mainly composed of carbon monoxide, hydrogen, methane, and carbon dioxide. This syngas can be used as an energy source for power generation, heating, industrial production, and many other fields. The working principle of a biomass gasifier is to convert biomass into gaseous fuel through the gasification reaction zone inside the gasifier, under controlled temperature and oxygen supply conditions, without complete combustion. Compared with traditional direct combustion technology, gasification technology is more efficient, emits fewer harmful substances, and can maximize the utilization of biomass energy.

[0003] Biomass gasifiers have broad application prospects. They can not only effectively reduce pollution from agricultural waste, but also provide clean and renewable energy for remote or energy-scarce areas. Through reasonable design, gasifiers can be adjusted according to different biomass feedstocks to improve gasification efficiency and energy conversion rate. In addition, gasifier technology is developing rapidly. Modern biomass gasifiers have integrated intelligent technologies such as automatic control and real-time monitoring, further improving the stability and reliability of the system. In general, as a green and environmentally friendly energy conversion device, biomass gasifiers have great development potential and are of positive significance for promoting sustainable development.

[0004] In a downdraft gasifier, raw materials are fed into the furnace from the top and gasified into combustible gas and char. The char is then conveyed out from the bottom of the gasifier by an auger. However, in traditional gasifiers, the tailings cannot be completely discharged after gasification and remain inside the gasifier, making cleaning inconvenient. To address this issue, a dry-discharge biomass gasifier is proposed to solve the above problems. Utility Model Content

A disassembly and assembly assembly is installed on the lower side of the gasifier body 1, and a vibration assembly is installed at the bottom of the gasifier body 1.

[0034] The assembly includes a side door 2 and a frame 3. The side door 2 is externally rotatably connected to the outside of the gasifier body 1, and the frame 3 is externally fixedly connected to the outside of the gasifier body 1. A rod 4 is slidably connected inside the frame 3, with an insertion hole 5 in the middle of the rod 4. A sliding plate 6 is fixedly connected to the right side of the rod 4, and a spring 7 is fixedly connected to the right side of the sliding plate 6. A stop bar 8 is slidably connected to the top of the frame 3. The side door 2 facilitates opening the gasifier body 1 to remove the internal waste material. The frame 3 connects and restricts the movement of other parts. The rod 4 is inserted into the side door 2 to stabilize it. The insertion hole 5 engages with the stop bar 8 to prevent the rod 4 from automatically resetting. Hole 5 is used to allow the stop bar 8 to be inserted. Slide plate 6 is used to withstand the thrust from spring 7 and drive the insert bar 4 to move. Spring 7 is used to push slide plate 6 to reset. A handle 17 is fixedly connected to the left end of insert bar 4. The handle 17 is used to facilitate manual pulling of insert bar 4. Slide plate 6 is externally slidably connected to the inner wall of frame 3 to limit the movement direction of slide plate 6. The stop bar 8 is externally inserted into the insertion hole 5 to prevent insert bar 4 from automatically resetting. The insert bar 4 is externally inserted into the side door 2 to keep the side door 2 stable. The bottom of stop bar 8 is slidably connected to the outside of insert bar 4 to control the timing of stop bar 8 falling. Spring 7 is fixedly connected to the left side of frame 3 to keep spring 7 stable.

[0035] Reference Figures 3-5The vibration assembly includes two supports 9, a motor 11, and two housings 13. The supports 9 are rotatably connected to the inner wall of the gasifier body 1. A filter plate 10 is fixedly connected between the two supports 9. The motor 11 is fixedly connected to the outside of the gasifier body 1, and a cam 12 is fixedly connected to the outside of the motor 11. The bottom of the housing 13 is fixedly connected to the bottom wall of the gasifier body 1. A second spring 14 is fixedly connected to the bottom wall of the housing 13. A baffle 15 is fixedly connected to the top of the second spring 14, and a pressure rod 16 is fixedly connected to the top of the baffle 15. The supports 9 support the filter plate 10, which filters out carbon separately. The motor 11 drives the cam 12 to rotate, and the cam 12 pushes the filter plate 10 to move. The housing 13 is used to connect and protect the internal parts. The second spring 14 is used to push the baffle 15 to move. The baffle 15 is used to bear the pressure of the pressure rod 16 and compress the second spring 14. The pressure rod 16 is used to bear the downward pressure of the filter plate 10. The filter plate 10 is sleeved inside the gasifier body 1 to keep the filter plate 10 stable. The cam 12 abuts against the bottom of the filter plate 10 to make the filter plate 10 flip upward. The baffle 15 is slidably connected to the inner wall of the housing 13. The pressure rod 16 is slidably connected to the inside of the housing 13. The housing 13 simultaneously restricts the movement direction of the baffle 15 and the pressure rod 16. The top of the pressure rod 16 abuts against the bottom of the filter plate 10 to support the filter plate 10 and push the filter plate 10 upward.

[0036] Working principle: When using the gasifier body 1 to gasify biomass materials, the material is placed into the top of the gasifier body 1, and the gasifier body 1 is started to operate, gasifying the material, evaporating and burning the moisture until the material becomes charcoal slag. At this time, the control motor 11 works, driving the cam 12 to rotate. Under the support of the bracket 9, the cam 12 pushes the filter plate 10 upward, causing the filter plate 10 to flip upward. When the cam 12 disengages from the filter plate 10, the filter plate 10 flips downward and squeezes the pressure rod 16, causing the pressure rod 16 to drive the baffle 15 to compress the second spring 14. The second spring 14, in turn, pushes the baffle 15 to drive the pressure rod 16 to reset and push the filter plate 10 upward. At this time, the filter plate 10 will swing up and down repeatedly. The vibration causes the material, which has turned into charcoal slag, to be filtered down and fall onto the bottom wall of the gasifier body 1. It is then conveyed out by an auger to complete the gasification. After all the material has been gasified, the insert rod 4 is pulled, causing the slide plate 6 to compress the spring 7, disengaging the insert rod 4 from the side door 2. At the same time, the stop rod 8 automatically falls down due to gravity and inserts into the insertion hole 5 to prevent the insert rod 4 from automatically resetting. Then, the side door 2 is opened, and the remaining tailings inside the gasifier body 1 are removed from the side door 2. The inside is cleaned, and then the side door 2 is closed. Then, the stop rod 8 is pulled up. At this time, the spring 7 will immediately push the slide plate 6, causing the insert rod 4 to reset and insert into the side door 2, fixing the side door 2 and preventing it from moving around. At this point, the gasification work can continue. The operation is convenient and labor-saving.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
