Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel production, and particularly relates to a straw crushing granulator with multiple crushing functions. Background Art

[0002] Biomass fuels are mainly fuels made from agricultural and forestry waste (such as straw, sawdust, bagasse, rice husks, etc.) and other organic waste (such as livestock and poultry manure, municipal waste, etc.) through specific processes. When using straw to make biomass fuels, it is necessary to first crush the straw and then press the straw powder into pellet fuels.

[0003] When some existing straw crushing granulators are in use, they lack an automatic secondary crushing mechanism and cannot automatically achieve secondary crushing of large particle straw.

[0004] For example, a straw crushing and granulating all-in-one machine disclosed in the patent with the publication number CN212916465U can quickly take out large particle straw scraps on the screening plate through the discharging component. Workers can manually slide the sliding bar out of the discharging groove through the handle. At this time, the discharging groove is in an open state, and under the action of the inclined screening plate, the large particle straw scraps fall into the receiving hopper, and the screening plate vibrates under the action of the vibration anti-blocking mechanism, so that the large particle straw on the screening plate can quickly fall into the receiving hopper through the discharging groove.

[0005] Although the straw crushing and granulating all-in-one machine of this patent has innovative designs such as a vibration anti-blocking mechanism and a discharging component, there are still some deficiencies in automatically processing large particle straw scraps. Although the discharging component can conveniently take out the large particle straw scraps on the screening plate, it is necessary for workers to manually collect these large particle straw for re-crushing, and the secondary crushing of large particle straw cannot be automatically achieved, increasing the complexity and workload of the operation.

[0006] Therefore, it is very necessary to invent a straw crushing granulator with multiple crushing functions to solve the above problems. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a straw crushing granulator with multiple crushing functions to solve the problems in the above technology.

[0008] To achieve the above object, the utility model provides the following technical solution: A straw pulverizing granulator with multiple crushing functions, including a pulverizing box and a granulator body. Inside the pulverizing box, a first pulverizing chamber, a second pulverizing chamber, and a third pulverizing chamber are sequentially arranged. Partition plates are arranged between the first pulverizing chamber, the second pulverizing chamber, and the third pulverizing chamber. A first discharge groove is formed on the surface of the partition plate between the first pulverizing chamber and the second pulverizing chamber, and a second discharge groove is formed on the surface of the partition plate between the second pulverizing chamber and the third pulverizing chamber. A first sieve plate is arranged inside the first pulverizing chamber. One end of the first sieve plate is hinged to the inner wall of the first pulverizing chamber, and the other end of the first sieve plate passes through the first discharge groove and extends into the second pulverizing chamber.

Vibration motors are installed at the bottoms of the first sieve plate and the second sieve plate.

[0009] Through the design of the first pulverizing chamber, the second pulverizing chamber, the third pulverizing chamber, the first sieve plate, and the second sieve plate, the straw pulverizing granulator can achieve multiple crushing of straw, ensure that the particle size of the straw particles is more uniform, and improve the quality of subsequent granulation.

[0014] Preferably, one end of the first sieve plate is arranged below the first pulverizing roller, the other end of the first sieve plate is arranged above the second pulverizing roller, one end of the second sieve plate is arranged below the second pulverizing roller, and the other end of the second sieve plate is arranged above the third pulverizing roller.

[0015] The design of the first sieve plate and the second sieve plate can screen the crushed straw. The straw particles that meet the requirements can pass through the sieve plate and enter the guide cylinder, while the straw particles with larger sizes are automatically discharged into the next-stage pulverizing chamber for continuous crushing, realizing multi-stage crushing and screening.

[0016] Preferably, the number of the first crushing rollers, the second crushing rollers and the third crushing rollers is set to two each. The two first crushing rollers are connected by gear transmission, the two second crushing rollers are also connected by gear transmission, and the two third crushing rollers are likewise connected by gear transmission.

[0024] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0025] 1. By arranging a first sieve plate and a second sieve plate between the first crushing chamber, the second crushing chamber and the third crushing chamber, the automatic screening function of the straw particles is realized. This design enables the straw particles that meet the requirements to be screened out in real time during the crushing process, and at the same time ensures that the larger particles can automatically enter the next-stage crushing chamber for further crushing, thereby improving the efficiency of the entire crushing process;

[0026] 2.

The second sieve plate 4 is driven by the vibration motor 5 to vibrate, and the straw particles after secondary pulverization are screened. The straw particles that meet the requirements after secondary pulverization are screened into the material guiding cylinder 15, while the larger particles are shaken into the third pulverizing chamber. The third pulverizing roller 11 is driven by the third motor 14 to perform tertiary pulverization on the straw particles falling into the third pulverizing chamber. After tertiary pulverization, the size of the straw particles reaches the granulation requirements and falls into the material guiding cylinder 15. The spiral auger 17 is driven by the fourth motor 16 to rotate in the material guiding cylinder 15, and the spiral auger 17 is used to push the straw particles in the material guiding cylinder 15 towards the feed port of the granulator body 2. After the straw particles enter the granulator body 2, through the treatment of the granulator body, finally, granular biomass fuel is made.
