Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically to a raw material feeding and dispersing component for a granulator. Background Technology

[0002] Biomass pellet fuel is produced by a pellet mill. Currently, biomass pellet mills on the market generally include three symmetrical pressure roller components. The pressure roller mechanism works in conjunction with the ring die extrusion chamber to rotate and extrude the raw materials fed into the pellet mill into a pellet structure. However, the structural design of existing biomass pellet mills still has certain defects. During the rotational extrusion process, the raw material distribution on the roller surface is uneven, and the amount of raw material on the upper part of the roller surface is small. This results in most of the upper extrusion chambers of the ring die not producing material or producing a small amount of material, leading to low production efficiency.

[0003] Therefore, there is an urgent need to provide a pellet mill feed dispersion component suitable for biomass pellet mills to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a raw material feeding and dispersing component for a pellet mill, which solves the problem that the raw material is unevenly distributed on the roller surface of the existing biomass pellet mill when the roller mechanism rotates and extrudes, and the amount of raw material on the upper part of the roller surface is small, resulting in most of the upper extrusion chambers of the ring die not discharging or discharging a small amount of material, resulting in low production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material feeding and dispersing component for a granulator, comprising a lifting knife disposed in the granulation chamber, a knife holder welded and fixed to the lifting knife, and a knife seat detachably and fixed to the knife holder. The knife holder is provided with a vertical adjustment groove, and the height of the knife holder mounted on the knife seat through the adjustment groove is adjustable. The knife seat is detachably and fixed to the upper transmission plate connected to the pressure roller.

[0006] The lifting blade is set in correspondence with the three sets of pressure rollers, and the lifting blade is located between two adjacent sets of pressure rollers and is set obliquely upward. The bottom end of the lifting blade is the feeding end, and the surface of the lifting blade is set with an inclined surface at the feeding end position. The side of the top of the lifting blade parallel to the roller surface is an arc surface, and extends around the roller surface from the bottom to the top along the arc of the roller surface.

[0007] Preferably, the tool holder is L-shaped, and the top of the tool holder is provided with a vertical circular mounting hole and a guide post. The upper transmission plate is provided with a vertical stud and a circular guide hole at the positions corresponding to the mounting hole and the guide post. The stud is connected to the mounting hole, the guide post is connected to the guide hole, and a nut is threaded onto the stud to lock and fix the tool holder.

[0008] Preferably, the tool holder is provided with at least two sets of horizontal studs on its side, and the studs are threaded with nuts to lock the tool holder in place at the adjustment groove.

[0009] This utility model has the following beneficial effects:

[0010] 1. This utility model features rotationally symmetrically distributed lifting blades. The lifting blades are angled upwards to lift and guide the raw material falling into the granulation chamber onto the surface of each pressure roller. The lifting blades, with their arc-shaped tops, guide the material from the bottom to the top of the pressure roller along the circumference of the pressure roller. This ensures that the raw material is evenly distributed onto the roller surface, guaranteeing sufficient raw material for smooth discharge at the extrusion position between the roller surface and the extrusion cavity on the ring die. This improves the discharge efficiency and ensures production output.

[0011] 2. This utility model features an adjustable lifting blade. The height of the lifting blade can be adjusted according to the weight of the raw material. When the raw material is light, the lifting blade can be adjusted to be lower, and when the raw material is heavy and cannot be lifted, the lifting blade can be adjusted to be higher.

[0018] 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.

[0019] like Figure 1-5 As shown, this utility model provides a technical solution: a raw material feeding and dispersing component for a pellet mill, including a lifting knife 1 installed in the pelleting chamber, a knife holder 2 welded and fixed to the lifting knife 1, and a knife seat 3 detachably installed and fixed to the knife holder 2. The knife holder 2 is provided with a vertical adjustment groove 21, and the height of the knife holder 2 installed on the knife seat 3 through the adjustment groove 21 is adjustable. The knife seat 3 is detachably installed and fixed on the upper transmission plate 5 connected to the pressure roller 4.

[0020] The tool holder 3 is L-shaped. The top of the tool holder 3 is provided with a vertical circular mounting hole 31 and a guide post 32. The upper transmission plate 5 is provided with a vertical stud 51 and a circular guide hole 52 at the positions corresponding to the mounting hole 31 and the guide post 32. The stud 51 is inserted into the mounting hole 31 and connected to the mounting hole 31. The guide post 32 is inserted into the guide hole 52 and connected to the guide hole 52. The threaded nut 6 on the stud 51 locks the tool holder 3 in place.

[0021] The tool holder 3 is provided with at least two sets of horizontal studs 33 on the side, and the studs 33 are threaded with nuts 7 to lock the tool holder 2 at the position of the adjustment groove 21;

[0022] The lifting knife 1 is set in correspondence with the three sets of pressure rollers 4. The lifting knife 1 is located between two adjacent sets of pressure rollers 4 and is set obliquely upward. The bottom end of the lifting knife 1 is the feeding end. The surface of the lifting knife 1 is provided with an inclined surface 11 for easy feeding at the feeding end position. The top of the lifting knife 1 is parallel to the roller surface of the pressure roller 4 on one side, which is an arc surface and extends around the roller surface from the bottom to the top along the arc of the roller 4.

[0023] During use, the lifting knife 1 rotates synchronously with the three sets of pressure rollers 4 connected to the upper transmission plate 5, lifting the raw material in the granulation process and guiding it to be dispersed onto the roller surface of each pressure roller 4. The lifting knife 1 guides the material from the bottom to the top of the pressure roller 4 through the arc-shaped top, so that the raw material can be evenly dispersed onto the roller surface of the pressure roller 4. This ensures that there is enough raw material to be discharged smoothly at the extrusion position of the roller surface and the extrusion cavity on the ring die, improving the discharge effect and ensuring the production output.
