Description

Technical Field

[0001] This utility model relates to the technical field of pyrolysis gasification equipment, specifically a segmented furnace body vertical rotary pyrolysis gasification furnace. Background Technology

[0002] A pyrolysis gasification furnace is an environmentally friendly energy device that combines purely mechanical structural design with thermochemical conversion to convert solid fuels (such as biomass, coal, and solid waste) into combustible gases under oxygen-deficient or oxygen-deficient conditions. Its core logic is to control the reaction environment through mechanical structure, achieving a two-step synergistic reaction of "pyrolysis" and "gasification," avoiding direct fuel combustion, while simultaneously efficiently recovering energy and reducing pollutant emissions.

[0003] Current traditional segmented pyrolysis gasifiers are unable to meet the requirements of high efficiency, energy saving, and continuous operation. They suffer from uneven feed crushing and low pyrolysis efficiency: the lack of a crushing structure or fixed crushing particle size results in incomplete pyrolysis of large pieces of material and agglomeration of small pieces of material. The residue after pyrolysis has a high carbon content, leading to serious energy waste. Furthermore, the lack of a preheating stage results in high energy consumption: the feed enters the pyrolysis section directly, requiring a large amount of energy generated by pyrolysis to heat the material. Utility Model Content

[0004] The purpose of this invention is to provide a segmented furnace body vertical rotary pyrolysis gasifier to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmented vertical rotary pyrolysis gasification furnace, comprising a pyrolysis section and a processing section. The processing section is fixedly connected to the upper part of the pyrolysis section. A fixed roller is rotatably connected to one side of the upper part of the processing section, and a first threaded rod is threadedly connected to the other side of the upper part of the processing section. A movable frame is rotatably connected to the tail of the first threaded rod, and an adjusting roller is rotatably connected inside the movable frame. Two sets of first guide rods are fixedly connected to one side of the movable frame, and the first guide rods are slidably connected to the inside of the side wall of the processing section. A filter screen is fixedly connected to the lower inner side of the processing section. A gas inlet pipe is fixedly connected to one end of the pyrolysis section, and several gas distribution pipes are fixedly connected to the other end of the upper part of the gas inlet pipe. The gas distribution pipes penetrate the processing section and face the upper part of the filter screen. A discharge port is opened on the side of the processing section away from the gas distribution pipes. Two sets of connecting frames are fixedly connected to the outer side of the processing section near the discharge port, and baffles are slidably connected inside the connecting frames.

[0006] Preferably, a guide plate is fixedly connected to the upper part of the processing section.

[0007] Preferably, a solenoid valve is fixedly connected to the upper outer side of the air intake pipe, and a filter plate is fixedly connected to the inside of one end of the air distribution pipe.

[0008] Preferably, a first motor is fixedly connected to the upper part of one side of the connecting frame, and a second threaded rod is fixedly connected to the power end of the first motor through the connecting frame. The lower part of the second threaded rod is rotatably connected to the lower side of the connecting frame. The second threaded rod is threadedly connected to the inside of one side of the baffle. A second guide rod is slidably connected to the inside of the other side of the baffle. The second guide rod is fixedly connected to the inside of the other side of the connecting frame.

[0009] Preferably, a discharge hopper directly opposite the discharge port is fixedly connected to the outside of the connecting frame.

[0010] Preferably, a fixed frame is fixedly connected to the upper outer side of the processing section, a second motor is fixedly connected to one side of the fixed frame, the power end of the second motor penetrates the fixed frame and the processing section and is fixedly connected to the fixed roller, a moving groove is opened on the other side of the fixed frame, a communicating groove is opened on one side of the processing section facing the moving groove, a moving plate is slidably connected inside the moving groove, a fourth motor is fixedly connected to one side of the moving plate, and the power end of the fourth motor sequentially penetrates the moving plate, the communicating groove and the moving frame and is fixedly connected to the adjusting roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses high-temperature hot gas generated in the pyrolysis section to preheat the feed material through the gas inlet pipe and gas distribution pipe, so that the temperature of the material increases before entering the pyrolysis section. This eliminates the need to consume a large amount of pyrolysis energy to heat the cold material, thus reducing energy consumption compared to structures without preheating and significantly reducing long-term operating costs. 2. This utility model uses a first threaded rod to drive the adjustment roller and the fixed roller to flexibly adjust the distance within a certain range, which can adapt to the crushing needs of different materials such as straw (fine material) and solid waste (coarse material). After crushing, the uniformity of the material particle size is improved, avoiding incomplete pyrolysis of large pieces of material or agglomeration of small pieces of material, thus improving the pyrolysis efficiency.

[0012] 3. This utility model uses a first motor to drive the baffle to automatically open and close, which, together with the discharge bin, collects large pieces of residue without manual operation, thus improving discharge efficiency. The hot air ejected from the air distribution pipe continuously blows the filter screen, and combined with regular discharge, the filter screen clogging rate is reduced, the continuous running time of the equipment is extended, and the downtime for cleaning is greatly reduced.

[0015] 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.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a segmented vertical rotary pyrolysis gasification furnace, comprising a pyrolysis section 1 and a processing section 2. The processing section 2 is fixedly welded to the upper part of the pyrolysis section 1. A fixed roller 3 is rotatably connected to one side of the upper part of the processing section 2 via a deep groove ball bearing. A first threaded rod 4 is threadedly connected to the inside of the other side of the upper part of the processing section 2. A movable frame 5 is rotatably connected to the tail of the first threaded rod 4 via a deep groove ball bearing. An adjusting roller 6 is rotatably connected to the inside of the movable frame 5 via a deep groove ball bearing, which cooperates with the fixed roller 3 to achieve material crushing. Two sets of first guide rods 7 are fixedly welded to one side of the movable frame 5. The first guide rods 7 are slidably connected to the inside of the side wall of the processing section 2 through clearance fit. To ensure the smooth movement of the mobile frame 5, a filter screen 9 is fixedly connected to the lower inner side of the processing section 2 by bolts. An air intake pipe 10 is fixedly connected to one end of the pyrolysis section 1 by welding. Several sets of evenly distributed air distribution pipes 11 are fixedly connected to the other end of the upper part of the air intake pipe 10 by welding. The air distribution pipes 11 penetrate the processing section 2, and the air outlet is directly facing the upper part of the filter screen 9. They are used to spray hot air for preheating and purging to prevent blockage. A rectangular discharge port 14 is opened on the side of the processing section 2 away from the air distribution pipes 11. Two sets of symmetrical connecting frames 16 are fixedly connected to the outer side of the processing section 2 near the discharge port 14 by welding. A baffle 20 is slidably connected inside the connecting frame 16 by clearance fit to control the opening and closing of the discharge port 14. The upper part of the processing section 2 is fixedly connected to the guide plate 8 by welding. The guide plate 8 guides the material to fall accurately between the fixed roller 3 and the adjusting roller 6, so as to avoid the material from scattering and improve the crushing efficiency. A solenoid valve 12 is fixedly connected to the upper outer side of the air intake pipe 10 via a flange. The solenoid valve 12 controls the hot air flow and can adjust the hot air flow according to the feed rate to balance the preheating effect and pyrolysis energy consumption. A filter plate 13 is fixedly connected to one end of the air distribution pipe 11 to prevent crushed materials from entering the air distribution pipe 11. A first motor 17 is bolted to the upper part of one side of the connecting frame 16. The power end of the first motor 17 penetrates the connecting frame 16 and is fixedly connected to a second threaded rod 18 through a coupling. The lower part of the second threaded rod 18 is rotatably connected to the lower side of the connecting frame 16 through a deep groove ball bearing. The second threaded rod 18 is threaded to the inside of one side of the baffle 20. A second guide rod 19 is slidably connected to the inside of the other side of the baffle 20 through a clearance fit. The second guide rod 19 is welded to the inside of the other side of the connecting frame 16 to ensure the smooth lifting and lowering of the baffle 20. The outer side of the connecting frame 16 is fixedly connected by welding to a discharge bin 15 facing the discharge port 14. The discharge bin 15 is used to collect large pieces of material that are not completely crushed, so as to facilitate subsequent re-crushing and avoid scattering and pollution. A fixed frame 21 is welded to the upper outer side of the processing section 2. A second motor 22 is bolted to one side of the fixed frame 21. The power end of the second motor 22 penetrates the fixed frame 21 and the processing section 2, and is fixedly connected to one end of the fixed roller 3 through a coupling. A rectangular moving groove 23 is opened on the other side of the fixed frame 21. A connecting groove 24 is opened on one side of the processing section 2, which is directly opposite to the moving groove 23. A moving plate 25 is slidably connected inside the moving groove 23 through clearance fit. A fourth motor 26 is bolted to one side of the moving plate 25. The power end of the fourth motor 26 penetrates the moving plate 25, the connecting groove 24 and the moving frame 5 in sequence, and is fixedly connected to one end of the adjusting roller 6 through a coupling, so as to realize the synchronous driving crushing of the two rollers.

[0017] Working principle: When using this utility model: according to the characteristics of the material to be processed, the first threaded rod 4 is rotated, and the deep groove ball bearing rotates to drive the moving frame 5 to slide along the first guide rod 7 to adjust the distance between it and the fixed roller 3; after the adjustment is completed, the second motor 22 and the fourth motor 26 are started, and the fixed roller 3 and the adjusting roller 6 are driven to rotate synchronously relative to each other through the coupling to prepare for crushing and feeding.

[0018] The material is fed into the upper part of the processing section 2, guided by the guide plate 8, and falls between the fixed roller 3 and the adjusting roller 6, where it is crushed by the double rollers. The solenoid valve 12 is opened, and the high-temperature hot gas generated in the pyrolysis section 1 is sprayed out through the air inlet pipe 10 and the air distribution pipe 11 to preheat the crushed material and reduce the energy consumption of subsequent pyrolysis. The preheated material passes through the filter screen 9 and enters the pyrolysis section 1 for pyrolysis and gasification. Large pieces of material that are not completely crushed are intercepted by the filter screen 9 and accumulate on the surface of the filter screen 9.

[0019] When hot air is ejected through the gas distribution pipe 11, it blows away the accumulated material on the surface of the filter screen 9 to prevent the filter screen 9 from clogging. The first motor 17 is started periodically to drive the second threaded rod 18 to rotate through the deep groove ball bearing, which drives the baffle 20 to slide upward along the second guide rod 19 and open the discharge port 14. Under the action of gravity and hot air blowing, the accumulated large pieces of material fall into the discharge bin 15 through the discharge port 14 for collection, and can be put back into the processing section 2 for crushing later. After the discharge is completed, the first motor 17 is started in reverse to drive the baffle 20 to descend and close the discharge port 14, and the pyrolysis operation continues.
