Background technique

With the continuous improvement of people's living standards, the demand for meat, eggs, milk and other animal foods has increased significantly, and the feed industry is playing an increasingly important role in the national economy. Energy shortage and environmental pollution have become two major problems hindering the development of today's society. In order to alleviate the contradiction between energy supply and demand, it is urgent to find renewable energy. Compared with many energy sources, biomass energy is a renewable and clean energy source, which stands out for its abundant resource reserves and huge development potential, and has received more and more attention from all over the world. However, the research on biomass molding technology in my country is still in its infancy and needs further development and improvement. The processing of biomass pellets by the flat die pellet machine is a kind of solidification molding technology. In the development process of the biomass pellet industry in recent years, the flat die machine has gradually won the favor of producers due to its advantages of durability and strong adaptability of raw materials. favor.

Threaded holes are evenly distributed on the upper, middle and lower three-layer flat dies. Through the cooperation of a certain number of bolts and nuts, the coaxial installation of the three-layer flat dies can always be kept stable. There are fine holes on the edge of each flat die. The narrow annular groove is used to place a thin layer of gaskets to further prevent the slippage of the flat dies of each layer in the working state.

First of all, put a suitable tapered roller bearing on the pressure roller shaft, the pressure roller sleeve 4 and the outer ring of the bearing are interference fit, there are key grooves on the pressure roller ring 3 and the pressure roller sleeve 4, and the flat key 2 The pressure roller 3 is installed on the pressure roller sleeve 4; wherein the snap ring 16 is placed between the two pressure roller rings 3 to reduce the wear between the pressure roller rings, and because the elasticity of the material of the snap ring is relatively high Large, can play a very good role in damping vibration.

Beneficial effects of the utility model: 1. When the pressure roller and the flat die plate are severely worn and need to be replaced, only the pressure roller ring or the upper flat die needs to be replaced; 2. The flat die is a combined die plate, which is convenient for maintenance and disassembly ; 3. The upper and lower flat die hole structures are symmetrical and can be used interchangeably, reducing production costs.

Detailed ways

Further illustrate the utility model in conjunction with accompanying drawing and embodiment:

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the utility model is a moving roller type flat die granulator, which mainly consists of a feeder 1, a flat key 2, a pressing roller ring 3, a pressing Roller sleeve 4, upper flat die 5, middle flat die 6, lower flat die 7, cutter 8, sweeping plate 9, motor 11, large pulley 10, small pulley 12, small bevel gear 13, main shaft 14, large bevel gear 15. The clasp ring 16 and the elastic retaining ring 17 are composed; the die hole of the flat die adopts a straight hole, and the feeding port is set as an inverted cone to reduce the feeding resistance, and the discharge port is provided with a decompression hole to reduce the pressure of pellets The resistance of the material passing through the die hole during the process. The flat die is composed of an upper flat die 5, a middle flat die 6, and a lower flat die 7; the die hole structure of the upper flat die 5 is an inverted cone, the die hole structure of the middle flat die 6 is cylindrical, and the die hole structure of the lower flat die 7 is a positive cone. Threaded holes are evenly distributed on the upper, middle and lower three-layer flat dies. Through the cooperation of a certain number of bolts and nuts, the coaxial installation of the three-layer flat dies can always be kept stable. There are fine holes on the edge of each flat die. The narrow annular groove is used to place a thin layer of gaskets to further prevent the slippage of the flat dies of each layer in the working state.

Firstly, put a suitable tapered roller bearing on the pressure roller shaft, and the pressure roller sleeve 4 is an interference fit with the outer ring of the bearing. Next, a circlip 17 is installed between the two pressure roller rings 3 to reduce the mutual contact area. There are key grooves on the pressure roller ring 3 and the pressure roller sleeve 4, and the pressure roller 3 is installed on the pressure roller sleeve 4 with the flat key 2; the snap ring 16 is placed between the two pressure roller rings 3 The gap is used to reduce the wear between the pressure roller rings. At the same time, because the material of the snap ring has a large degree of elasticity, it can play a very good role in damping vibration.

The working principle of the moving roller type flat die granulator: the motor 11 is transmitted to the bevel gear reducer 13 and 15 through the small pulley 10 and the large pulley 12, thereby driving the main shaft 14, and the main shaft 14 drives the pressure roller sleeve 4, because the pressure roller ring 3 Fixed on the pressure roller sleeve 4, the pressure roller sleeve 4 revolves around the main shaft 14 and also rotates around the pressure roller axis, thereby driving the pressure roller ring 3 to rotate; the upper flat die 5, the middle flat die 6 and the lower flat die are fixed by screws Become integral flat mold together, and three flat molds keep the midline positions coincident and fixed. When processing pellets, the biomass raw material is sent into the feeding chamber of the flat die machine, and spread evenly on the upper flat die 5 under the joint action of the feeder 1 and the scraper, and the pressure roller ring 3 driven by the main shaft 14 continuously Rolling through the material layer, the material is extruded into the die hole. The material undergoes the process of forming and maintaining the shape in the die hole. After a certain period of time, it is extruded in a cylindrical state. The rotating cutter 8 cuts the material to form particles. The material plate 9 sends out the particles;

Improvement of the pressure roller: Change the pressure roller to a combined type, the pressure roller ring 3 is fixed by the flat key 2 and the elastic retaining ring 17, the pressure roller sleeve 4 directly acts as the outer ring of the bearing, and the bearing is composed of the bearing end cover and the shaft shoulder on the shaft Positioning is carried out, when the pressure roller is severely worn during use and needs to be replaced, only the pressure roller ring 3 needs to be replaced.

Improvement to the flat die: the flat die is divided into upper flat die 5, middle flat die 6, and lower flat die 7 according to the shape of the die hole; 5. When it needs to be replaced due to wear and tear, since the three-layer flat die is fixed by screws at the threaded holes on the flat die, it is easy to disassemble, and the lower flat die 7 and the upper flat die 5 can be exchanged directly, which reduces the production cost and improves Later maintenance is more convenient.
