Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a mixing equipment for biomass fuel preparation. Background Technology

[0002] Biomass fuels refer to combustible materials obtained from plants, animals, and other biological organisms and their waste through direct combustion or processing via physical, chemical, or biological methods. They possess advantages such as renewability and low pollution. Common biomass fuels include sawdust, straw, livestock manure, food processing waste, algae, and municipal organic waste. These can be converted into solid, liquid, or gaseous fuels through compression molding, bio-fermentation, pyrolysis, and gasification for power generation, heating, or transportation. Biomass fuels effectively reduce dependence on fossil fuels, contribute to achieving carbon neutrality goals, and are an important pathway to promoting sustainable energy development.

[0003] In the preparation of liquid biomass fuel, the mixing process of raw materials is crucial. Currently, commonly used liquid biomass fuel mixing equipment generally adopts a single mechanical stirring structure. Due to the lack of wall-scraping and cleaning devices, it is difficult to prevent vegetable oils such as rapeseed oil, peanut oil, and soybean oil, or animal fats, from excessively adhering to the tank wall with alcohols such as methanol and ethanol during the stirring process. At the same time, existing mixing equipment is not equipped with effective filtration or separation mechanisms, and cannot remove clumps or impurities generated during the stirring process in a timely manner. This not only leads to frequent equipment cleaning and maintenance and reduced mixing efficiency, but also easily causes problems such as uneven reaction and product quality fluctuations, which seriously restricts the application and promotion of large-scale, continuous production of liquid biomass fuel.

[0004] Based on this, we propose a mixing device for biomass fuel production to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a mixing device for biomass fuel preparation, which can solve the problems in liquid biomass fuel mixing equipment, such as the lack of wall scraping and cleaning devices and filtration and separation structures, which leads to the adhesion of vegetable oil and alcohol substances to the tank wall, the inability to remove impurities in time, resulting in frequent equipment cleaning and maintenance, low mixing efficiency, uneven reaction and product quality fluctuations.

[0007] To solve the above technical problems, this utility model provides a mixing device for biomass fuel preparation, which adopts the following technical solution: it includes a support box base, a mixing tank is installed on the top of the support box base, an anti-sticking stirrer is installed inside the mixing tank, an impurity filter assembly is also provided on one side of the top of the support box base, a circulation conveying assembly is provided on one side of the mixing tank, and a discharge pipe is connected to the side of the mixing tank away from the circulation conveying assembly;

[0008] The support box has a storage cavity inside. A feed inlet is mounted on the top of the support box near the storage cavity. A flow guide channel runs through the storage cavity and the feed inlet. A motor drive box is installed at the top of the inner cavity of the storage cavity. The output end of the motor drive box is connected to a first transmission disc, which is located at the bottom of the inner cavity of the mixing tank.

[0009] Optionally, the circulating conveying assembly includes a circulating pump, one end of which is connected to a first liquid extraction pipe.

The end of the circulating pump away from the first liquid extraction pipe is also connected to a second liquid extraction pipe. The liquid extraction port of the second liquid extraction pipe is located at the bottom of the inner cavity of the storage cavity.

[0010] Optionally, the anti-stick stirrer includes a second transmission disk, which is structurally matched with the first transmission disk and is fixedly connected to the first transmission disk. A stirring shaft is connected to the top of the second transmission disk, and several sets of circumferentially arrayed stirring plates are distributed on the outer side of the stirring shaft.

[0011] Optionally, an embedded groove is provided on one side of the stirring plate, and an anti-stick scraper is also provided inside the embedded groove.

[0012] Optionally, an inner plate is installed on one side of the anti-stick scraper, and a top pressure plate is provided on one side of the inner plate. The top pressure plate, the inner plate and the inner groove structure are matched, and multiple sets of compression springs are also distributed at equal intervals between the top pressure plate and the inner plate.

[0013] Optionally, the impurity filtration assembly includes a baffle frame, the bottom of which is provided with a metal filter screen, the metal filter screen being matched with the feed inlet structure, and the metal filter screen and the feed inlet having a transition fit.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The biomass fuel mixing equipment designed in this scheme is equipped with an impurity filtration component at the feed inlet. When various liquid biomass raw materials are injected into the support box, particulate impurities in the raw materials can be effectively filtered. At the same time, the circulation conveying component can transport the filtered raw materials to the mixing tank, which can realize the efficient mixing of various liquid biomass raw materials, ensure the purity of the raw materials entering the mixing tank, provide a good material foundation for the subsequent mixing process, and improve the mixing effect.

[0016] 2. The biomass fuel mixing equipment designed in this scheme uses a motor drive box as its core power source.

An anti-sticking scraper installed on one side of the agitator's mixing plate can scrape away substances from the inner wall of the mixing tank, preventing excessive adhesion of vegetable oil, animal fat, and alcohols. Through the interaction of the top pressure plate, the inner plate, and the compression spring, the anti-sticking scraper can achieve adaptive elastic adjustment, preventing jamming due to unevenness of the mixing tank's inner wall. This also facilitates the disassembly, installation, maintenance, and replacement of the anti-sticking scraper, achieving effective cleaning of the mixing tank's inner wall and long-term stable operation, improving mixing efficiency and product quality.

[0025] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of a mixing device for biomass fuel preparation, including a support base 1, a mixing tank 2 mounted on the top of the support base 1, an anti-sticking stirrer 3 installed inside the mixing tank 2, an impurity filter assembly 4 also provided on one side of the top of the support base 1, a circulation conveying assembly 5 provided on one side of the mixing tank 2, and a discharge pipe 6 connected to the side of the mixing tank 2 away from the circulation conveying assembly 5. A storage cavity 7 is formed inside the support base 1, and an inlet 8 is mounted on the top of the side of the support base 1 near the storage cavity 7. A guide channel 9 runs through the storage cavity 7 and the inlet 8. A motor drive box 10 is mounted on the top of the inner cavity of the storage cavity 7, and the output end of the motor drive box 10... The transmission is connected to a first transmission disc 11, which is located at the bottom of the inner cavity of the mixing tank 2. The biomass fuel mixing equipment can filter particulate impurities in various liquid biomass raw materials by adding an impurity filter component 4 at the inlet 8. The filtered liquid biomass raw materials can flow into the storage cavity 7 along the guide channel 9 and be transported to the inside of the mixing tank 2 by the circulation conveying component 5 added to one side of the top of the support box 1. During the mixing process, the inner wall of the mixing tank 2 can be scraped and cleaned by the anti-stick scraper 20 added to one side of the stirring plate 18, which can prevent excessive adhesion between vegetable oil or animal fat, alcohol and the inner wall of the mixing tank 2.

[0026] The circulation conveying assembly 5 includes a circulation pump 12. One end of the circulation pump 12 is connected to a first liquid extraction pipe 13. A flow guide 14 is installed at the end of the first liquid extraction pipe 13 away from the circulation pump 12. The flow guide 14 is located at the top of the mixing tank 2. The end of the circulation pump 12 away from the first liquid extraction pipe 13 is also connected to a second liquid extraction pipe 15. The liquid extraction port of the second liquid extraction pipe 15 is located at the bottom of the inner cavity of the storage cavity 7. Through the circulation conveying assembly 5 installed on one side of the mixing tank 2, which consists of the circulation pump 12, the first liquid extraction pipe 13, the flow guide 14, and the second liquid extraction pipe 15, it can continuously extract and transport various liquid biomass raw materials from the storage cavity 7 into the mixing tank 2. This works in conjunction with the impurity filter assembly 4 installed at the inlet 8 opening. The system achieves multi-stage impurity interception and removal, thereby ensuring the uniformity of circulation of various liquid biomass raw materials during the stirring process, improving mixing efficiency, and ensuring stable and reliable system operation. The anti-sticking stirrer 3 includes a second transmission disk 16, which is structurally matched with the first transmission disk 11 and is fixedly connected to the first transmission disk 11. The top of the second transmission disk 16 is connected to a stirring shaft 17, and several sets of circumferentially arrayed stirring plates 18 are distributed on the outer side of the stirring shaft 17. Through the structural design of the fixed connection between the second transmission disk 16 and the first transmission disk 11, when the motor drive box 10 installed on the top of the storage cavity 7 is powered on, it can drive the stirring shaft 17 and stirring plates 18 to mix and stir various liquid biomass raw materials inside the mixing tank 2.

[0027] An inner groove 19 is provided on one side of the stirring plate 18. An anti-stick scraper 20 is also installed inside the inner groove 19. The anti-stick scraper 20, installed on one side of the stirring plate 18, can scrape and clean the inner wall of the mixing tank 2, preventing excessive adhesion of vegetable oil, animal fat, or alcohols to the inner wall of the mixing tank 2. An inner plate 21 is installed on one side of the anti-stick scraper 20, and a top pressure plate 22 is provided on one side of the inner plate 21. The top pressure plate 22, the inner plate 21, and the inner groove 19 are structurally matched. Multiple sets of compression springs 23 are equidistantly distributed between the top pressure plate 22 and the inner plate 21. Through the interaction between the top pressure plate 22 and the inner plate 21... Multiple sets of compression springs 23, evenly distributed, can adaptively and elastically adjust the anti-stick scraper 20 for wall cleaning, preventing excessive contact between the anti-stick scraper 20 and the uneven inner wall of the mixing tank 2, which could cause the anti-stick scraper 20 to jam. The impurity filtration assembly 4 includes a baffle frame 24, with a metal filter screen 25 at the bottom of the baffle frame 24. The metal filter screen 25 is structurally matched with the feed inlet 8, and there is a transition fit between the metal filter screen 25 and the feed inlet 8. By installing the metal filter screen 25 at the bottom of the baffle frame 24, and with the transition fit between the metal filter screen 25 and the feed inlet 8, the metal filter screen 25 can be embedded and fixed at the opening of the feed inlet 8.

[0028] Working Principle: In this biomass fuel mixing equipment design, various liquid biomass raw materials are injected into the support box 1 through the feed inlet 8. The support box 1, equipped with an impurity filter assembly 4 at the feed inlet 8, filters particulate impurities from the liquid biomass raw materials. The filtered liquid biomass raw materials flow into the storage cavity 7 along the guide channel 9 and are then transported to the mixing tank 2 via a circulation conveying assembly 5 installed on one side of the top of the support box 1. During mixing, a motor drive box 10 installed at the top of the storage cavity 7 serves as the core power source. Its output is connected to a first transmission disc 11, and the first transmission disc 11 and the second transmission disc 16 are fixedly connected, enabling anti-sticking mixing. Inside the mixing tank 2, the mixer 3 mixes and stirs various liquid biomass raw materials. The anti-sticking mixer 3, with an anti-sticking scraper 20 installed on one side of the stirring plate 18, can clean the inner wall of the mixing tank 2, preventing excessive adhesion of vegetable oil, animal fat, alcohol and other substances to the inner wall of the mixing tank 2. Through the cooperation of the top pressure plate 22, the inner plate 21 and the compression spring 23, the anti-sticking scraper 20 can also be adjusted elastically to prevent excessive contact between the anti-sticking scraper 20 and the uneven inner wall of the mixing tank 2, which would cause the anti-sticking scraper 20 to jam. At the same time, the anti-sticking mixer 3 can also be disassembled, connected and repaired according to the usage of the anti-sticking scraper 20.
