Description

Technical Field

[0001] The utility model belongs to the technical field of a contact sealing feeder for a biomass gasifier, and particularly relates to a contact sealing feeder for a biomass gasifier. Background Art

[0002] For biomass air gasification, the required air supply is much lower than that for combustion. When air leaks into a local area and the oxygen concentration of the local high-temperature gas and fly ash reaches the explosion condition, gas explosion is likely to occur. Therefore, it is very important to tightly seal the feeding port to prevent air from entering. Currently, the commonly used impeller sealing feeder has a relatively large gap between the moving and static parts. Biomass fuel is relatively loose, and under a certain furnace negative pressure, the amount of air intake is relatively large. This not only affects the normal air supply for biomass gasification but also often causes local deflagration in the furnace due to air leakage, affecting normal production. After researching and testing the current lever-type sealed impeller feeder and the local slider-type sealed impeller feeder of the casing, problems such as jamming and air leakage exist to varying degrees with respect to biomass straw.

[0003] A contact sealing feeder for a biomass gasifier is disclosed, with the publication number: CN204589089. The beneficial effects are as follows: This sealing feeder is applicable to the feeding of biomass gasifiers and coal gasifiers. It can completely form a sealed feeding to avoid the deflagration of gas in the furnace caused by air leakage.

[0004] After using this contact sealing feeder for the biomass gasifier, sealed feeding can be successfully achieved, the furnace negative pressure is stable, and no gas deflagration phenomenon occurs. However, in the actual use process, a large number of agglomerated materials cannot be completely refined and burned. There are cavities in some of the fuels, and a large amount of gas is stored in the cavities, and there is still a risk of deflagration. Based on this, a contact sealing feeder for a biomass gasifier is proposed to solve the above problems. Content of the Utility Model

[0026] To better understand the purpose, structure, and function of the present utility model, the following provides a more detailed description of a contact-type sealed feeder for a biomass gasifier of the present utility model in conjunction with the accompanying drawings.

[0027] As Figures 1-4 shown, a contact-type sealed feeder for a biomass gasifier of the present utility model includes an external device 1. The external device 1 is provided with a connecting pipe 2, and a connecting mechanism 3 is provided at the bottom of the connecting pipe 2. The connecting mechanism 3 includes a main body component 31 provided at the bottom of the connecting pipe 2. The main body component 31 is connected to a transmission component 32, and the bottom of the main body component 31 is connected to a blanking component 33. The transmission component 32 includes a fixed block 326 and a fixed stop block 329. A fixed rod 325 is slidably connected to the inner wall of the limiting hole opened in the fixed block 326. A connecting spring 327 is sleeved on the outer wall of the fixed rod 325. The outer end of the fixed rod 325 is fixedly connected to a transmission rack plate 324. The transmission rack plate 324 meshes with a rotating gear 323. A rotating rod 321 is fixedly connected to the inner wall of the rotating gear 323. A feeding blade 322 is fixedly connected to the outer wall of the rotating rod 321. The main body component 31 includes a feeding pipe 311 communicated at the bottom of the connecting pipe 2. The bottom of the feeding pipe 311 is communicated with a casing 312. A driving motor 313 is fixedly installed at one end of the back of the casing 312. The output end of the driving motor 313 is fixedly connected to a rotating shaft 314. A rotating disk 315 is fixedly connected to the outer wall of the rotating shaft 314. The blanking component 33 includes a blanking pipe 331. A connecting rod 332 is rotatably connected to the inner wall of the blanking pipe 331. A blanking disk 333 is fixedly connected to the outer wall of the connecting rod 332. A resisting groove 334 is opened at the outer end of the blanking disk 333.

The transmission rack plate 324 is slidably connected to the outer wall of the transmission rack plate 324. The driving motor 313 is rotatably connected to the inner wall of the casing 312. The blanking pipe 331 is communicated at the bottom of the casing 312.

[0028] The working principle of the contact-type sealed feeder for the biomass gasifier: During the actual use of the contact-type sealed feeder for the biomass gasifier, the bottom of the connected external device 1 is communicated with a connecting pipe 2. Biomass fuel enters the connecting pipe 2 through the external device 1 and falls along the connecting pipe 2 to the feeding pipe 311 communicated at the bottom of the connecting pipe 2. A running driving motor 313 is fixedly installed on the outer wall of the casing 312 communicated at the bottom of the feeding pipe 311. The running driving motor 313 drives the rotating shaft 314 fixedly connected to the output end to rotate. The rotating disk 315 fixedly connected to the outer wall of the rotating shaft 314 rotates accordingly, and the biomass fuel falling into the inner cavity of the driving motor 313 is thus driven for feeding.

[0029] A fixed stop block 329 is fixedly connected to the inner wall of the casing 312. A fixed block 326 is fixedly connected to the bottom of the rotating rotating disk 315. The rotating rotating disk 315 drives the connected abutting block 328 to rotate. The rotating abutting block 328 is abutted by the connected fixed stop block 329 and then moves. The driving rack plate 324 fixedly connected to the moving abutting block 328 moves accordingly. The fixed rod 325 fixedly connected to the inner wall of the driving rack plate 324 is slidably connected to the inner wall of the limiting hole opened in the fixed block 326. The connecting spring 327 sleeved on the outer wall of the fixed rod 325 is compressed accordingly. The rotating gear 323 meshed with the driving rack plate 324 rotates, driving the rotating rod 321 fixedly connected to the inner wall to rotate. The feeding blades 322 fixedly connected to the outer wall of the rotating rotating rod 321 rotate to feed and crush the biomass fuel, avoiding the existence of large pieces of materials and the risk of deflagration.

[0030] A connecting rod 332 is rotatably connected to the inner wall of the blanking pipe 331 communicated with the bottom of the casing 312. A feeding disk 333 is fixedly connected to the outer wall of the connecting rod 332. The rotating abutting block 328 fluctuates to rotate the abutting groove 334 opened in the connected feeding disk 333, so that the crushed biomass fuel can be fed again randomly, avoiding the still existence of some agglomerated materials and affecting subsequent use.

[0031] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, these features and embodiments can be variously changed or equivalently replaced. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
