Description

Technical Field

[0001] The utility model belongs to the technical field of biomass power generation, and particularly relates to a biomass power generation feeding control device. Background Art

[0002] Biomass power generation is to generate electricity by using the biomass energy possessed by biomass, which is a kind of renewable energy power generation, including direct combustion power generation of agricultural and forestry waste, gasification power generation of agricultural and forestry waste, waste incineration power generation, landfill gas power generation, and biogas power generation. In biomass power generation, it is necessary to transport the biomass raw materials used for power generation.

[0003] In the Chinese patent with the publication number of CN220489196U, a biomass power generation feeding control device is mentioned. Through the arranged dispersion mechanism, the raw materials are dispersed by rotation in multiple directions, further avoiding the aggregation of raw materials and making it difficult to burn fully, resulting in waste of raw materials.

[0004] Although the biomass power generation feeding control device in the above-mentioned prior art can disperse the raw materials, the biomass raw materials are usually directly transported to the power generation area after being collected from the farmland. Hard objects such as stones are often carried in biomass such as straw, and these hard objects such as stones are likely to damage the dispersion blades, thus affecting the service life of the device. For this reason, we propose a biomass power generation feeding control device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a biomass power generation feeding control device to solve the problem that hard objects such as stones carried in biomass such as straw in the prior art are likely to damage the dispersion blades.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. Through the arrangement of the inclined rod, transmission rod, guide plate and guide rod, the present utility model can screen out hard objects such as stones carried in biomass materials such as straw during use, effectively avoiding damage to the device during the treatment of biomass materials, and improving the service life of the device.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Refer to Figures 1-6 As shown, the present utility model provides a biomass power generation feeding control device, including a housing 1, a feeding hopper 2 fixedly connected to the top of the housing 1, a feeding conveyor belt 3 arranged at the bottom of the housing 1, and a processing mechanism 4 arranged on the front side of the housing 1;

[0028] The processing mechanism 4 includes a stepping motor 405, the stepping motor 405 is fixedly connected to the front side of the housing 1, the stepping motor 405 is fixedly connected with a transmission rod 406 through an output shaft, guide rods 402 are arranged at equal intervals on the outer side of the transmission rod 406, two symmetrically distributed cutting rollers 409 are arranged inside the housing 1, a material guiding plate 403 is fixedly connected inside the housing 1, and a collection box 411 is arranged at the bottom of the housing 1.

[0029] In a further embodiment, refer to Figures 1-3 and Figures 5-6 , inclined rods 401 are fixedly connected to the right side inside the housing 1 at equal intervals. The equal interval distribution of the inclined rods 401 is adapted to the distribution of the material guiding rods 402, and the inclined rods 401 are located between two adjacent material guiding rods 402, so that the inclined rods 401 do not affect the rotation of the material guiding rods 402, and when the material guiding rods 402 rotate, the biomass materials on the inclined rods 401 can be lifted and located between two adjacent material guiding rods 402 for conveying the biomass materials. Convex strips 407 are fixedly connected to the outer side of the material guiding plate 403 at equal intervals. The convex strips 407 are provided to remove the biomass materials on the material guiding rods 402 and make them enter the material guiding plate 403. Stop blocks 410 are fixedly connected to the inside of the collection box 411. The stop blocks 410 are used for limiting the mesh plate 412. A mesh plate 412 is arranged inside the collection box 411. Two symmetrically distributed round holes are opened in the middle of the mesh plate 412 for taking out the mesh plate 412.

[0030] In this embodiment, the biomass material added through the feeding hopper 2 falls on the inclined rod 401. Hard objects such as stones in the biomass material enter the collection box 411 below the housing 1 under the action of gravity. By dealing with hard objects such as stones in the biomass material, damage to the device caused by them can be avoided.

[0031] In a further embodiment, referring to Figures 1-2 and Figure 4 , a baffle 404 is arranged on the left side of the cutting roller 409 group. The baffle 404 is used to block the biomass material so that it can enter between the two cutting rollers 409. The baffle 404 is fixedly connected to the inner side of the housing 1. A servo motor 408 is fixedly connected to the rear side of the housing 1. The servo motor 408 can provide power for the rotation of the two cutting rollers 409. The servo motor 408 is equipped with an output shaft. The output shaft of the servo motor 408 is fixedly connected to the front end of one of the cutting rollers 409 through a coupling. The servo motor 408 can drive the cutting roller 409 to rotate through the output shaft and the coupling. Gears are fixedly connected to the outer sides of the two cutting rollers 409. The opposite faces of the two gears are meshed with each other. When one cutting roller 4 is rotated, the two cutting rollers 409 rotate in opposite directions under the action of the two gears, so as to cut the biomass material. The feeding conveyor belt 3 is arranged below the two cutting rollers 409. The cut biomass material will fall on the feeding conveyor belt 3 and be conveyed to the combustion furnace of the power generation equipment.

[0032] In this embodiment, the processed biomass material enters between the two cutting rollers 409 under the action of the guide plate 403 and is cut into sections. The combustion efficiency of the cut biomass material is improved.

[0033] The working principle of the present utility model is as follows:

[0034] The biomass material to be burned for power generation is put in through the feeding hopper 2. The put biomass material falls on the inclined rod 401 under the action of gravity. Hard objects such as stones carried in it pass through the gaps between the inclined rods 401 under the action of gravity and enter the collection box 411 below for collection;

[0035] The stepper motor 405 drives the transmission rod 406 to rotate through the output shaft. The rotation of the transmission rod 406 picks up the biomass material on the inclined rod 401 through the guide rod 402, enters the left guide plate 403 under the rotation action, and then enters between the two cutting rollers 409 through the guide plate 403. The feeding speed of the biomass material can be adjusted by adjusting the rotation speed of the stepper motor 405;

[0036] The servo motor 408 drives the cutting roller 409 to rotate through the output shaft and the coupling. Under the rotation of the cutting roller 409, the biomass material is cut into sections. The cut biomass material falls on the feeding conveyor belt 3 and is transported to the power generation combustion equipment. The mesh plate 412 is regularly removed to process hard objects such as stones in the collection box 411.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
