Technical Field

The invention relates to the technical field of pellet machines, in particular to a forming and pelletizing device for processing material fuel particles.

Background technique

Biomass pellet machine is a kind of biomass energy pretreatment equipment, which mainly uses agricultural and forestry waste such as wood chips, straw, rice husks, bark and other biomass as raw materials. Through pretreatment and processing, it is solidified into high-density pellet fuel. The commonly used forming and granulating equipment for material fuel pellet processing are as follows: flat die pelletizer, ring die pelletizer, double roller pelletizer, extrusion pelletizer; among them, the ring die pellet machine is also known as ring die pellet feed machine, ring die pellet feed forming machine, which belongs to feed pelletizing equipment. The straw ring die pellet machine is a machine that presses biomass raw materials such as straw into pellets. The pellets it produces can not only be used as fuel, but also as feed.

Since the pellet mill ring die is a porous annular part, the working conditions are bad. During use, it is subjected to the extrusion force of the roller and the friction of the material for a long time, which causes bending stress and contact pressure stress. Since the ring die is subjected to alternating action during the pelletizing process, its alternating stress is asymmetrically cyclic, so the ring die usually suffers from fatigue damage, so that after the ring die has worked for a period of time, the inner wall of each small hole of the material discharge is worn, the hole diameter increases, and the diameter of the pellet feed produced exceeds the specified value and fails.

The ring die of the granulator is a porous annular part with harsh working conditions. During use, it is subjected to the extrusion force of the pressure roller and the friction force of the material for a long time, which causes bending stress and contact pressure stress. Since the ring die is subjected to alternating action during the granulation process, its alternating stress is asymmetrically cyclic, so the ring die usually suffers from fatigue damage. By setting a double shell of a cylinder and a limiting cylinder, the width and thickness of the ring die can be effectively increased, the bending resistance and productivity of the ring die can be improved, and the service life of the ring die can be extended. The limiting cylinder is fixedly connected to a fixed block at one end close to the reset spring, and a square groove is provided at one end of the cylinder close to the fixed block. Protrusions are symmetrically arranged inside the square groove. During operation, the fixed block slides between the two protrusions in the square groove, so that the limiting cylinder moves on the surface of the cylinder, and then the limiting cylinder and the cylinder are fixed.

By setting the spiral plate, uneven material distribution can be avoided. When entering the extrusion, the extrusion stress and friction force of the cylinder and the limit plate appear uneven along the axial direction, which eventually leads to uneven wear of the cylinder and the limit plate. At the same time, by setting the arc-shaped circular groove, the material falls and contacts with the inner wall of the circular groove first, avoiding direct contact between the material and the spiral plate.

The present invention provides a forming and granulating device for material fuel particle processing. It has the following beneficial effects:

1. The forming and granulating equipment for the fuel pellet processing of the material has a porous annular part through the pelletizing machine ring die, which has harsh working conditions. During use, it is subjected to the extrusion force of the roller and the friction of the material for a long time, which causes bending stress and contact pressure stress. Since the ring die is subjected to alternating action during the pelletizing process, its alternating stress is asymmetrically cyclic, and the ring die usually suffers from fatigue damage.

2. The forming and granulating equipment for processing fuel particles of this material makes the material fall evenly between the limit plate and the cylinder, and sets a spiral plate to avoid uneven distribution of the material. When entering the extrusion, the extrusion stress and friction force of the cylinder and the limit plate appear uneven along the axial direction, which eventually leads to uneven wear of the cylinder and the limit plate.

Since the material contains more impurities, especially some materials may contain sand and iron impurities, the impurities will accelerate the wear of the cylinder and the limit plate. By setting the filter plate, the material can be removed from the impurities, which can reduce the friction between the material and the ring die. At the same time, the screened material can pass through the circular hole more conveniently, and the appearance of the formed particles is smoother.

Under the action of the material's own gravity, the rotating plate 44 is forced to rotate, and the rotating plate 44 rotates to apply force to the filter plate 43. The elastic performance of the compression spring 42 is used to make the filter plate 43 move up and down to remove impurities from the material. After passing through the filter plate 43, the material falls along the lower hopper 41 into the circular groove 74 at the top of the cone 72, and then enters between multiple spiral plates 73 along the circular groove 74. Under the action of centrifugal force and the limiting of the spiral plate 73, the material falls evenly between the limiting plate 471 and the cylinder 61, and the motor 5 drives the cylinder 61 to rotate, so that the material is continuously extruded with high strength under the action of centrifugal force and the friction between the limiting plate 471 and the cylinder 61 to form columnar particles.

The electric push rod 31 extends during operation, so that the electric push rod 31 drives the fixed plate 32 and the end fixed to the electric push rod 31 to move in the direction away from the extension block 25, so that the fixed plate 32 drives the support rod 34 to move in the direction of the limiting cylinder 63, and then the cutter 37 cuts off the columnar particles on the outer wall of the limiting cylinder 63. The length of the columnar particles is adjusted by controlling the working interval time of the electric push rod 31. At the same time, the bottom of the support block 38 is set to be inclined. Under the elastic force of the spring plate 35, the cutter 37 moves up and down during the cutting process, which is convenient for reducing the generation of waste slag.

After the columnar particles on the outer wall of the limiting cylinder 63 are cut off, they enter the interior of the outer shell 21 and then fall onto the circular plate 22. During the cutting process, some waste slag will be generated. By setting the circular plate 22, the produced materials are filtered, and the columnar particles remain on the circular plate 22. The waste slag falls to the bottom of the outer shell 21 through the circular plate 22. The waste slag is collected and recycled.
