Description

Technical Field

[0001] This utility model belongs to the technical field of biomass gasification furnaces, and in particular relates to a biomass gasification furnace with a spiral feed. Background Technology

[0002] A waste-to-biomass gasification furnace is a device that uses biomass gasification technology to treat municipal waste. It converts the organic matter in the waste into syngas or other usable energy sources. This effectively reduces the amount of waste while generating clean energy, helping to solve the dual problems of waste disposal and energy supply.

[0003] Currently, most biomass gasification furnaces use a spiral feeding method. However, there is an unavoidable gap between the spiral blades and the tube wall, which causes the raw material to clump together on the inner side of the tube wall, easily causing blockage and affecting normal feeding.

[0004] To address the aforementioned issues, this application proposes a biomass gasifier with spiral feed that can clean the pipe wall in real time during feeding, thereby preventing blockages. Utility Model Content

[0005] The purpose of this invention is to provide a biomass gasification furnace with a spiral feed, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a biomass gasification furnace with a spiral feed, including a generator and a discharge pipe at its lower end, and a storage hopper and a feed pipe at its lower end, the feed pipe being connected to the generator;

[0008] The end of the feed pipe furthest from the generator is detachably fitted with a cover and a motor on its side. The motor shaft extends into the inside of the feed pipe, and a spiral blade is fixedly connected to the outside of the shaft. An external protrusion is detachably connected to the outside of the spiral blade.

[0009] An oblique scraper extends from the side of the protrusion adjacent to the generator, and a spherical protrusion is fixedly connected to the side of the protrusion away from the generator. Both the scraper and the spherical protrusion are attached to the inner wall of the feed pipe.

[0010] Furthermore, the inner side of the protruding part is a transition part, and an inner opening groove is provided inside it, which is fitted onto the outer side of the spiral blade.

[0011] Furthermore, a transversely penetrating coaxial positioning hole is provided near the outer side of the spiral blade and near the inner side of the transition part.

[0012] Furthermore, a bolt is inserted into the positioning hole, and an adapter cap is spirally connected to the end of the bolt away from the generator. The plate at the other end of the bolt and the adapter cap press against the outer side of the adapter part.

[0013] Furthermore, the interior of the adapter is provided with a push rod perpendicular to the motor shaft, and a plug rod is fixedly connected to the end of the push rod away from the spiral blade, which is inserted into the plug hole extending outward from the slot.

[0014] Furthermore, the other end of the push rod abuts against the outer wall of the spiral blade.

[0015] Furthermore, the push rod releases an outward tightening force to the adapter.

[0016] This utility model has the following beneficial effects:

[0017] This invention lays the protruding part along the outer edge of the spiral blade, so that the scraper blade adheres to the inner wall of the feed pipe under the action of the top rod. This allows the solidified material adhering to the inner wall of the feed pipe to be scraped off in real time during spiral feeding, thereby solving the problem of blockage caused by the raw material caking inside the pipe wall.

[0018] This utility model uses the hollow structure of the adapter to be directly fitted onto the outside of the spiral blade, so that the protruding part can be aligned with the outer edge of the spiral blade, realizing a separable assembly structure that can be disassembled, cleaned, or repaired and replaced at any time during long-term use.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Please see Figure 1-4 As shown, this utility model is a biomass gasification furnace with a spiral feed, including a generator 11 and a discharge pipe 14 at its lower end, and also includes a storage hopper 12 and a feed pipe 13 at its lower end, the feed pipe 13 being connected to the generator 11.

[0036] A cover 131 and a motor 132 on its side are detachably installed at the end of the feed pipe 13 away from the generator 11. The rotating shaft of the motor 132 extends into the inside of the feed pipe 13. A spiral blade 133 is fixedly connected to the outside of the rotating shaft. An external protrusion 135 is detachably connected to the outside of the spiral blade 133. The external protrusion 135 adopts a high-temperature resistant flexible mechanism, which can be laid according to different pitches of the spiral blades 133.

[0037] An oblique scraper 1351 extends from the side of the protrusion 135 adjacent to the generator 11, which is used to scrape out the raw material at the inner wall of the feed pipe 13. A spherical protrusion 1352 is fixedly connected to the side of the protrusion 135 away from the generator 11, which is used to squeeze the raw material that has clumped on the inner wall of the feed pipe 13, so that its edge is raised and scraped out by the scraper 1351. Both the scraper 1351 and the spherical protrusion 1352 are attached to the inner wall of the feed pipe 13.

[0038] Preferably, the inner side of the protrusion 135 extends a transition portion 134, and an inwardly opening slot 1341 is provided inside it. The cross-section of the slot 1341 forms an inverted U-shaped groove, which is then fitted onto the outer side of the spiral blade 133, so that the two side plates partially overlap with the outer ring area of ​​the spiral blade 133.

[0039] Preferably, a transversely penetrating coaxial positioning hole 1331 is provided near the outer side of the spiral blade 133 and near the inner side of the adapter 134. A bolt 136 is inserted into the positioning hole 1331. One end of the bolt 136 away from the generator 11 is spirally connected to an adapter cap 1361. The other end of the bolt 136 and the adapter cap 1361 press against the outer side of the adapter 134. The bolt 136 is inserted into the positioning hole 1331, connecting the left and right plates on the inner side of the adapter 134 to the spiral blade 133 as a whole. As the spiral connection depth between the bolt 136 and the adapter cap 1361 increases, it compresses the two plates on both sides of the adapter 134, forming a tight fixation.

[0040] Preferably, the interior of the adapter 134 is provided with a push rod 137 perpendicular to the rotating shaft of the motor 132. The end of the push rod 137 away from the spiral blade 133 is fixedly connected to a plug rod 1371, which is inserted into the plug hole 1342 extending outward from the slot 1341. Utilizing the same high-temperature resistant elastomer properties of the adapter 134 and the outward protrusion 135, the plug rod 1371 can be automatically clamped and fixed by friction when it is inserted into the plug hole 1342.

[0041] Preferably, the other end of the push rod 137 abuts against the outer wall of the spiral blade 133. After the bolt 136 connects the adapter 134 and the spiral blade 133 together, the push rod 137 is squeezed inward. When the spiral blade 133 is installed inside the feed pipe 13, the squeezed push rod 137 releases the outward pressing force, thereby pushing the adapter 134 outward to form an expansion, thereby increasing the fit between the scraper 1351 and the inner wall of the feed pipe 13.

[0042] Understandably, this utility model can clean the inner wall of the feed pipe 13 in real time during the spiral feeding process, which can not only prevent some raw materials from sticking to the inner wall and causing blockage, but also make it easy to disassemble the cleaning mechanism during long-term use, which is convenient for cleaning, inspection and maintenance.

[0043] A specific application of the operation process in this embodiment is as follows: First, the motor 132 is moved outward using the separation structure of the cover 131 and the feed pipe 13, thereby removing the spiral blade 133 on the outer side of its rotating shaft; then, the empty groove 1341 on the inner side of the adapter 134 is fitted onto the outer edge of the spiral blade 133, and the adapter cap 1361 is screwed on by the bolt 136, and after passing through the positioning hole 1331, the adapter 134 is clamped on both sides of the spiral blade 133, thereby forming a fixation; at this time, the push rod 137 located inside the empty groove 1341 releases the tightening force outward. This causes the outer portion of the adapter 134 to expand outward, so that when the spiral blade 133 is installed inside the feed pipe 13, it drives the scraper 1351 on one side of the protrusion 135 to adhere to the inner wall of the feed pipe 13. This allows the material that has clumped on the inner wall of the feed pipe 13 to be scraped off in real time when the spiral blade 133 rotates to feed, thereby preventing blockage. At the same time, the spherical protrusion 1352 on the outer side of the protrusion 135 will also squeeze some of the solidified material, causing its edge to lift up, so that it can be easily scraped off when the scraper 1351 rotates to that area again.
