Abstract
Description
Technical Field

[0002] Biomass block fuel, as a renewable energy source, is widely used in industrial boilers, power generation equipment, and residential heating.
[0003] In actual production, the mixing and conveying of biomass block fuel is a critical process that directly affects combustion efficiency and equipment stability. Traditional biomass fuel mixing and feeding devices mostly use manual feeding or simple mechanical conveying methods. Manual feeding or a single conveying mechanism makes it difficult to achieve uniform mixing of multiple materials. Block fuel exerts a significant impact on the conveying mechanism during feeding, which can easily cause scratches or damage to the equipment surface and shorten the equipment's service life. Traditional devices lack control over the material feeding speed, resulting in uneven load on the conveying mechanism and affecting production efficiency. Utility Model Content

[0006] Furthermore, the buffer control mechanism includes a guide rod, a threaded rod, and a buffer block. The guide rod is fixed on the middle inner wall of the feed hopper, the threaded rod is rotatably mounted on the middle inner wall of the feed hopper, the buffer block is threadedly connected to the threaded rod and slidably connected to the guide rod, and a rotating wheel is fixed at the upper end of the threaded rod.
[0007] Furthermore, a fixing strip is fixed to the outer edge of the lower end port of the first and second guide ports, and a flexible plate is fixed to the inner end of the fixing strip. The flexible plate is symmetrically arranged at the discharge port of the first and second guide ports.

[0019] 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.
[0020] Please see Figure 1-5This utility model provides a technical solution: a biomass block fuel mixing and feeding device, specifically composed of a feeding bin 1 and a conveying mechanism 2. The conveying mechanism 2 is existing technology and will not be described in detail here. The lower end of the feeding bin 1 is fixedly connected to a connecting guide port 6 and a connecting guide port 7. The discharge ports of the guide ports 6 and 7 are correspondingly set to the upper end of the conveying mechanism 2, and the discharge ports are staggered. This way, the materials will not interfere with each other when falling onto the conveying mechanism 2. A buffer control mechanism is set inside the guide ports 6 and 7. A connecting mechanism is set at the end of the conveying mechanism 2. The outer end of the connecting mechanism is connected to a material elevator 3. The material elevator 3 mixes and transports the materials. The material elevator 3 lifts the materials by conveying them upward through the internal hopper and discharges them from the discharge pipe 4 on the upper side of the material elevator 3. The material elevator 3 is existing technology and will not be described in detail here. It is more efficient than the traditional manual cross-feeding and mixing method.
[0021] The connecting mechanism includes a mixing pipe 9 and a connecting pipe 10. The mixing pipe 9 is arranged in a triangular shape and is fixedly connected to the connecting pipe 10. The connecting pipe 10 is connected to the material elevator 3. The port of the mixing pipe 9 is connected to the end of the conveying mechanism 2. A dust cover 8 is fixedly connected to the upper end of the mixing pipe 9. The dust cover 8 can block the dust raised by the falling material and prevent the dust from flying.
[0022] The buffer control mechanism includes a guide rod 13 and a threaded rod 14. The guide rod 13 is fixed on the middle inner wall of the feed hopper 1, and the threaded rod 14 is rotatably mounted on the middle inner wall of the feed hopper 1. A buffer block 15 is provided on the threaded rod 14 and the guide rod 13, wherein the buffer block 15 is threadedly connected to the threaded rod 14, and the guide rod 13 is slidably connected to the buffer block 15. A rotating wheel 16 is fixedly connected to the upper end of the threaded rod 14. By rotating the rotating wheel 16, the threaded rod 14 is driven to rotate. Under the restriction of the guide rod 13, the buffer block 15 can move up and down. The height of the buffer block 15 can be adjusted according to the size of the material block, thereby controlling the material feeding speed and facilitating adjustment.
[0023] A fixing strip 11 is fixed to the outer edge of the lower end port of the first guide port 6 and the second guide port 7. A flexible plate 12 is fixed to the inner side of the fixing strip 11. The flexible plate 12 is symmetrically arranged at the lower end of the material inlet of the first guide port 6 and the second guide port 7. When the material inside is discharged, the slowing effect of the flexible plate 12 can reduce the impact on the conveying mechanism 2 and avoid scratching or damaging the surface of the conveying mechanism 2.
[0024] A dust suction pipe 5 is fixedly connected to the top of the material elevator 3. The dust suction pipe 5 can extract the dust inside the material elevator 3, thereby reducing the dust inside the material elevator 3 and extending the service life of the material elevator 3.
