Description

Technical Field

[0001] The utility model relates to the technical field of biomass fiber product separation, and particularly relates to a separation device for processing biomass fiber products. Background Art

[0002] Biomass fiber products are mainly composed of three major components: cellulose, lignin, and hemicellulose. These components each play different functions in biomass. However, due to the differences in their physical and chemical properties, a separation device is required for separation during the processing and utilization process. Mechanical forces (such as cutting, tearing, grinding, etc.) are used to separate the fibers in the biomass raw materials for subsequent processing and utilization.

[0003] Existing separation devices do not have the functions of uniform feeding and uniform crushing.

[0004] For example, a fiber separator with relatively high precision for papermaking production disclosed in the patent with the publication number CN215668731U only has a stirring rod inside the separator. This may result in non-uniform and weak crushing of the fiber raw materials in the integrated box. Single-point crushing easily causes excessive crushing of the raw materials in local areas while insufficient crushing in other areas. Moreover, only one feeding port is provided in this separator, which may lead to problems such as blockage and unreasonable distribution of the fiber raw materials during feeding, resulting in non-uniform feeding of the raw materials and affecting the subsequent crushing and processing effects.

[0005] Therefore, it is necessary to invent a separation device for processing biomass fiber products to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a separation device for processing biomass fiber products to solve the problems of non-uniform feeding and non-uniform crushing in the technology.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A separation device for processing biomass fiber products, including a separation box, a feeding tank, and a screening box. A bracket is arranged on the outside of the separation box. Disks are arranged on the left and right sides inside the separation box. Stirring and crushing paddles are arranged on the disks. A driving gear and a driven gear are arranged on one side of the disk. A driving motor is arranged outside the separation box. A first pulley group is arranged on one side of the driving motor. A feeding tank is arranged above the separation box. A spiral auger is arranged inside the feeding tank. One end of the spiral auger is provided with a second pulley group and is located outside the feeding tank. A feeding bin is arranged at the bottom of the feeding tank and extends into the separation box.

[0008] Preferably, the first pulley set consists of a large pulley, a small pulley and a belt. The belt is tensioned on the large pulley and the small pulley. The small pulley is connected to the output shaft of the drive motor, and the large pulley is fixed on the shaft of the driving gear. Through the cooperation of the large pulley and the small pulley, the power transmission from the drive motor to the driving gear is realized.

[0009] Preferably, driven gears are arranged at the upper and lower ends of the driving gear. There are 2 driven gears. The two driven gears are meshed with the driving gear. The meshed connection between the driving gear and the two driven gears realizes the distribution and transmission of power.

[0010] Preferably, there are 3 stirring and crushing paddles. One of the stirring and crushing paddles is connected to the driving gear, and the other two stirring and crushing paddles are connected to the driven gears, so that the three stirring and crushing paddles can work synchronously, improving the crushing efficiency.

[0011] Preferably, the second pulley set consists of two pulleys and a belt. The belt is tensioned on the two pulleys. One of the pulleys is connected to the shaft of the screw auger, and the other pulley is connected to the output shaft of the driving gear through a coupling. By connecting the screw auger and the output shaft of the driving gear through the second pulley set, the synchronous feeding and crushing are realized.

[0012] Preferably, there are multiple feeding bins. The multiple feeding bins are evenly arranged in a straight line at equal intervals. The feeding port of the feeding bin directly faces the feeding port of the separation box, ensuring that the biomass raw materials can enter the separation box evenly and stably, avoiding the problems of blockage and accumulation.

[0013] Preferably, a discharge port is arranged at the bottom of the separation box. A screening box is arranged below the discharge port. The discharge port of the discharge port is communicated with the feeding port of the screening box, which is used for further screening treatment of the crushed biomass fibers.

[0014] Preferably, a filter tank and a collection tank are slidably installed inside the separation box. The collection tank is directly below the filter tank of the filter tank. The filter tank can perform preliminary filtration treatment on the biomass fibers, and the collection tank is used to collect the biomass fibers after filtration, which is convenient for subsequent processing and utilization.

[0015] In the above technical solution, the technical effects and advantages provided by the present utility model are:

[0016] 1. By setting three stirring and crushing paddles, the three stirring and crushing paddles can work at the same speed through the transmission of the driving gear and the driven gear. The simultaneous operation of the three stirring and crushing paddles enables the biomass raw materials to be subjected to a more uniform and intense crushing effect within the separation box. This multi-point crushing method can reduce the particle size of the raw materials faster, improve the crushing efficiency, and create better conditions for the subsequent screening and processing processes.

[0017] 2. By setting the screw auger, the screw auger continuously and evenly conveys the biomass fiber products from the feeding tank to multiple discharging bins through its rotational motion. Since there are multiple discharging bins and they are distributed at different positions, it can not only reduce the production interruption problem caused by the blockage of a single discharging port, but also help the biomass raw materials to be discharged evenly and stably, ensuring the uniformity and consistency during the crushing process, thereby improving the crushing effect and product quality.

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] The present utility model provides as Figures 1-5A separation device for processing biomass fiber products as shown includes a separation box 1, a feeding tank 9, and a screening box 14. A support 2 is provided on the outer side of the separation box 1. On the left and right sides inside the separation box 1, there are discs 3. On the discs 3, there are stirring and crushing paddles 4. On one side of the disc 3, there are a driving gear 7 and a driven gear 8. Outside the separation box 1, there is a driving motor 5. On one side of the driving motor 5, there is a first pulley group 6. Above the separation box 1, there is a feeding tank 9. Inside the feeding tank 9, there is a spiral auger 10. One end of the spiral auger 10 is provided with a second pulley group 11 and is located outside the feeding tank 9. The bottom of the feeding tank 9 is provided with a feeding bin 12 which extends into the separation box 1.

[0027] The first pulley group 6 consists of a large pulley, a small pulley, and a belt. The belt is tensioned on the large pulley and the small pulley. The small pulley is connected to the output shaft of the driving motor 5, and the large pulley is fixed on the shaft of the driving gear 7. There are driven gears 8 at the upper and lower ends of the driving gear 7. There are 2 driven gears 8. The two driven gears 8 are meshed with the driving gear 7. There are 3 stirring and crushing paddles 4. One of the stirring and crushing paddles 4 is connected to the driving gear 7, and the other two stirring and crushing paddles 4 are connected to the driven gears 8.

[0028] Three stirring and crushing paddles 4 are provided. One is directly connected to the driving gear 7, and the other two are respectively connected to the two driven gears 8. The driving gear 7 is meshed with the two driven gears 8 to ensure that the three stirring and crushing paddles 4 can rotate synchronously at the same speed. This design enables the biomass raw materials to be subjected to a more uniform and stronger crushing effect inside the separation box 1. Thus, through the synchronous operation of the first pulley group 6 and the three stirring and crushing paddles 4, the uniform and strong crushing of the biomass raw materials inside the separation box 1 is achieved, significantly improving the crushing efficiency.

[0029] The second pulley group 11 consists of two pulleys and a belt. The belt is tensioned on the two pulleys. One of the pulleys is connected to the shaft of the spiral auger 10, and the other pulley is connected to the output shaft of the driving gear 7 through a coupling. There are multiple feeding bins 12. The multiple feeding bins 12 are evenly arranged in a straight line at equal intervals. The feeding openings of the feeding bins 12 are directly aligned with the feeding opening of the separation box 1.

[0030] Multiple feeding bins 12 are provided. Driven by the second pulley group 11, the spiral auger 10 continuously and evenly conveys the biomass fiber products from the feeding tank 9 into the multiple feeding bins 12. The design of the multiple feeding bins 12 ensures that the biomass fiber products can be continuously and evenly conveyed into the separation box 1, avoiding production interruption problems caused by blockage of a single feeding opening and accumulation of materials at the same position.

[0031] A discharge port 13 is provided at the bottom of the separation box 1, and a screening box 14 is provided below the discharge port 13. The discharge opening of the discharge port 13 is communicated with the feed inlet of the screening box 14. A filter tank 15 and a collection tank 16 are slidably installed inside the separation box 1, and the collection tank 16 is directly below the filter tank 15.

[0032] The filter tank 15 and the collection tank 16 in the screening box 14 are designed such that good pulp and impurities can be effectively separated, improving the purity and quality of the product. Moreover, the slidable installation design of the filter tank 15 and the collection tank 16 enables them to be conveniently taken out and cleaned, enhancing the maintainability and service life of the equipment.

[0033] The working principle of the present utility model:

[0034] Refer to the attached Figures 1-4 specification. When using the present utility model, first place the biomass fiber product into the feeding tank 9. The spiral auger 10 rotates driven by the second pulley group 11, and conveys the biomass fiber product in the feeding tank 9 downward to the blanking bin 12. The blanking bin 12 evenly distributes the biomass fiber product to multiple locations of the blanking bin 12 and directly feeds it into the separation box 1. The three stirring and crushing pulps 4 in the separation box 1 are driven to rotate by the driving motor 5 through the first pulley group 6, the driving gear 7 and the driven gear 8. The rotation of the three stirring and crushing pulps 4 stirs and crushes the biomass fiber product entering the separation box 1.

[0035] Refer to the attached Figure 5 specification. When using the present utility model, the crushed biomass fiber product enters the screening box 14 through the discharge port 13. Through the filtering action of the filter tank 15, the crushed biomass fiber product is separated from impurities. The impurities enter the collection tank 16 through the filter tank 15 for centralized collection and await subsequent cleaning. In the later stage, simply slide and pull out the filter tank 15 and the collection tank 16 to carry out disassembly and cleaning, and the operation is simple and convenient.
