Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biomass feeding integrated devices, and specifically relates to a biomass feeding integrated device. Background Art
[0002] The biomass feeding integrated device is a key component in biomass gasification technology. It is responsible for stably and continuously feeding biomass raw materials into a gasifier or reactor to ensure the smooth progress of the gasification process. When the biomass feeding integrated device is in use, a silo is generally required to store biomass, and the silo can store a large amount of biomass. However, when the environmental humidity is high, it is inevitable that the biomass will become wet. Excessive humidity may reduce the gasification temperature, extend the gasification time, or even cause incomplete gasification. At the same time, wet biomass may generate more water and tar during the gasification process, which will affect the quality of the gasified gas and subsequent utilization, and there are certain deficiencies. Content of the Utility Model
[0003] The utility model aims to solve the problems existing in the prior art or related technologies.
[0004] For this reason, the technical solution adopted by the utility model is as follows: A biomass feeding integrated device includes a screw conveyor, a silo, a heating component, a feeding pipe, a hot air inlet pipe, and a sealing plate. The silo is arranged on the screw conveyor. A connecting pipe for connecting the screw conveyor is provided at the bottom of the silo, and a humidity sensor is provided on the connecting pipe. The heating component includes a first fixing plate abutted against the outside of the connecting pipe, a second fixing plate screwed to the first fixing plate, and a heating pipe provided inside the first fixing plate and the second fixing plate. The feeding pipe is arranged at the bottom of the screw conveyor. The hot air inlet pipe is provided on the feeding pipe. The sealing plate is bolted to the left side of the screw conveyor, and an exhaust pipe is provided on the left side of the sealing plate.
[0005] Preferably, a screw blade is provided inside the screw conveyor, and the screw blade is fixedly connected to a rotating motor. An anti-sticking coating is provided outside the screw blade, and the anti-sticking coating is evenly sprayed with anti-sticking paint.
[0006] Preferably, a first electric valve is provided on the hot air inlet pipe, and the hot air inlet pipe is fixedly connected to a hot air supply device.
[0007] Preferably, a second electric valve is provided on the exhaust pipe, and the exhaust pipe is fixedly connected to an air extraction pump.
[0008] Preferably, metal wire meshes for blocking biomass are provided at the ports of the exhaust pipe and the hot air inlet pipe.
[0009] Preferably, a transparent plate is provided at the exact middle position of the sealing plate, and the vertical section of the transparent plate is circular.
[0010] By adopting the above technical solutions, the beneficial effects achieved by the present utility model are as follows: By providing a humidity sensor, a heating component, a hot air inlet pipe, and an exhaust pipe, the drying effect is achieved without affecting the biomass feeding, avoiding the problem that the high humidity of the biomass affects the gasification efficiency and quality. At the same time, by providing an anti-sticking coating, it is convenient to convey relatively moist biomass. During use, the humidity sensor can be used to detect the humidity of the biomass in the silo in real time. When the humidity is high, the heating pipe can be controlled to heat, preliminarily drying the biomass. Then, the hot air supply device can convey hot air into the feeding pipe through the hot air inlet pipe to further dry the biomass. The moist air after drying can be discharged through the exhaust pipe, effectively avoiding the problem that the wet biomass affects the gasification efficiency and quality. At the same time, the anti-sticking coating can reduce the viscosity of the spiral blade to facilitate the conveyance of wet biomass. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1:
[0026] Refer to Figures 1-5 , which is the first embodiment of the present utility model. This embodiment provides a biomass feeding integrated device, including a screw conveyor 100, a silo 200, a heating assembly 300, a feed pipe 400, a hot air inlet pipe 500 and a sealing plate 600.
[0027] Specifically, a screw blade 101 is arranged inside the screw conveyor 100, and the screw blade 101 is fixedly connected to a rotating motor. An anti-sticking coating 102 is arranged outside the screw blade 101, and the anti-sticking coating 102 is evenly sprayed with an anti-sticking paint. During use, the viscosity of the screw blade 101 can be reduced through the anti-sticking coating 102 to facilitate the transportation of wet biomass, and the rotating motor can drive the screw blade 101 to rotate. The rotating screw blade 101 can push the biomass to move for transportation.
[0028] Specifically, the silo 200 is arranged on the screw conveyor 100. A connecting pipe 201 for connecting the screw conveyor 100 is arranged at the bottom of the silo 200, and a humidity sensor 202 is arranged on the connecting pipe 201. The control terminal is electrically connected to the humidity sensor 202. During use, the silo 200 can store biomass, and the biomass can be transported into the screw conveyor 100 through the connecting pipe 201, and then the humidity of the biomass in the silo 200 can be detected in real time through the humidity sensor 202.
[0029] Specifically, the heating component 300 includes a first fixing plate 301 abutted against the outside of the connecting pipe 201, a second fixing plate 302 screw-connected to the first fixing plate 301, and a heating pipe 303 disposed inside the first fixing plate 301 and the second fixing plate 302. During use, the control terminal is electrically connected to the heating pipe 303. When the humidity is relatively high, it will feedback to the control terminal, and the control terminal will turn on the power supply of the heating pipe 303 of the heating component 300. The heated heating pipe 303 will heat up, and the biomass can be preliminarily dried.
[0030] Specifically, the feed pipe 400 is arranged at the bottom of the screw conveyor 100. During use, the feed pipe 400 can convey biomass into the gasifier or reactor.
[0031] Specifically, the hot air inlet pipe 500 is arranged on the feed pipe 400. A first electric valve 501 is arranged on the hot air inlet pipe 500, and the hot air inlet pipe 500 is fixedly connected to the hot air supply device. During use, the first electric valve 501 can be opened. After opening, the hot air supply device can convey hot air into the feed pipe 400 through the hot air inlet pipe 500, and the biomass can be further dried.
[0032] Specifically, the sealing plate 600 is bolted to the left side of the screw conveyor 100. An exhaust pipe 601 is arranged on the left side of the sealing plate 600. A second electric valve 602 is arranged on the exhaust pipe 601, and the exhaust pipe 601 is fixedly connected to the air extraction pump. A transparent plate 604 is arranged at the exact middle position of the sealing plate 600, and the vertical section of the transparent plate 604 is circular. During use, the air extraction pump can extract the moisture inside the screw conveyor 100 through the exhaust pipe 601 to facilitate drying the biomass.
[0033] It should be noted that metal wire meshes 603 for blocking biomass are arranged at the ports of the exhaust pipe 601 and the hot air inlet pipe 500. During use, the metal wire meshes 603 facilitate blocking the biomass and preventing the biomass from entering the exhaust pipe 601 and the hot air inlet pipe 500.

When the humidity is relatively high, it will feedback to the control terminal, and the control terminal will turn on the power supply of the heating pipe 303 of the heating component 300. The heated heating pipe 303 will heat up, and the biomass can be preliminarily dried. Then, the hot air supply device can convey hot air into the feed pipe 400 through the hot air inlet pipe 500, and the biomass can be further dried. The dried moisture can be discharged through the exhaust pipe 601, effectively avoiding the problem that the wet biomass affects the gasification efficiency and quality. At the same time, the anti-adhesion coating 102 can reduce the viscosity of the screw blade 101 to facilitate the conveyance of wet biomass.
