Description

Technical Field

[0001] This utility model relates to the field of biomass fuel production and processing technology, and in particular to a biomass fuel raw material cooling device. Background Technology

[0002] Biomass fuel mainly refers to biomass pellet fuel, a columnar environmentally friendly new energy source produced by processing straw, rice straw, rice husks, peanut shells, corn cobs, camellia husks, cottonseed husks, and other "three wastes" (residue, waste materials, and solid waste). Its production process mainly includes impurity removal and cleaning, crushing, drying, cooling, and pelletizing. After drying, the biomass fuel raw materials are at a relatively high temperature. If directly piled up, they are prone to re-moistening and require rapid cooling. Common methods for cooling biomass fuel raw materials include natural spreading and sun-drying or simple mechanical stirring. Natural spreading and sun-drying is greatly affected by weather and site conditions, resulting in low cooling efficiency and difficulty in ensuring uniform cooling. While simple mechanical stirring improves cooling speed to some extent, it lacks effective heat dissipation measures, cannot quickly lower the raw material temperature, and also suffers from uneven mixing and easy accumulation of raw materials, making it difficult to meet the needs of large-scale, high-efficiency production. Therefore, there is an urgent need to develop an efficient, stable biomass fuel raw material cooling device that can guarantee effective cooling. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a biomass fuel raw material cooling device. It uses an inverted conical platform structure to collect the material at the bottom, and then continuously transports and turns it from bottom to top by an auger, so that the material is fully turned and the heat dissipation is more uniform and efficient. The water cooling method is environmentally friendly and stable. With continuous turning and stirring, the material can be fully and evenly attached to the inner wall of the water cooling base for heat exchange. The top protective shield does not hinder heat dissipation and can also shield and protect the material. The device is easy to operate and has a high degree of automation.

The water-cooled base 1 is provided with a material storage tank 8. The bottom of the material storage tank 8 is provided with a discharge port 9. The material storage tank 8 and the outer wall of the water-cooled base 1 are hollow. The water-cooled base 1 is provided with a water inlet pipe 3 and a water return pipe 5 connected to a water tank. The water inlet pipe 3 is provided with a water pump structure 4. The water-cooled base 1 is provided with a material turning and cooling structure and a shielding structure. The bottom of the water-cooled base 1 is provided with an opening and closing cover 6 that cooperates with the discharge port 9.

[0025] In a preferred embodiment, the bottom of the water-cooled base 1 is provided with a guide unloading groove 7.

[0026] In a preferred embodiment, the material turning and cooling structure includes a support frame 10 disposed on the top of the water-cooled base 1. The support frame 10 is connected to the drive motor 17 via a fixed base 16. The output end of the drive motor 17 is connected to one end of a rotating shaft 18. The other end of the rotating shaft 18 is connected to the storage tank 8 via a support base 19. The rotating shaft 18 is provided with spiral blades 20.

[0027] In a preferred embodiment, the rotating shaft 18 is provided with a side support plate 21, and the side support plate 21 is provided with a flipping plate 22 that cooperates with the inner wall of the storage trough 8.

[0028] In a preferred embodiment, the two sides of the flipping plate 22 are symmetrically provided with scraping arc surfaces.

[0029] In a preferred embodiment, the storage trough 8 is an inverted frustum-shaped trough that is wider at the top and narrower at the bottom.

[0030] In a preferred embodiment, the shielding structure includes shielding frames 12 symmetrically arranged on both sides of the support frame 10. One end of the shielding frame 12 is connected to the support frame 10 via a hinge structure 11. The shielding frame 12 is provided with a breathable mesh 13, and the other end of the shielding frame 12 is provided with a magnetic attraction strip 15. The magnetic attraction strip 15 magnetically engages with a magnetic plate 14 provided on the support frame 10.

[0031] Example 2:

[0032] like Figure 1-6 In this system, the water-cooled base 1, as the core component of the device, has multiple sets of support legs 2 installed at its bottom to provide stable support for the entire device. The water-cooled base 1 contains a storage tank 8 for storing biomass fuel raw materials that need to be cooled. The storage tank 8 is an inverted truncated cone-shaped tank, wider at the top and narrower at the bottom, which facilitates the accumulation and unloading of raw materials. The bottom of the storage tank 8 has a discharge port 9 for discharging the cooled raw materials. The bottom of the water-cooled base 1 has an opening and closing cover 6 that cooperates with the discharge port 9. By controlling the opening and closing of the opening and closing cover 6, the unloading process is controlled. The water-cooled base 1 is also equipped with a guide unloading groove 7 at the bottom, which can guide the raw materials to be discharged smoothly from the unloading port 9. The storage tank 8 and the outer wall of the water-cooled base 1 are hollow structures. The water-cooled base 1 is equipped with an inlet pipe 3 and a return pipe 4 that are connected to the water pool. A water pump structure is installed on the inlet pipe 3. When working, the water pump structure pumps the water in the water pool into the hollow structure of the water-cooled base 1 through the inlet pipe 3. After the water circulates and absorbs heat in the hollow structure, it flows back to the water pool through the return pipe 4, forming a water circulation cooling system to cool the storage tank 8.

[0033] Example 3:

[0034] like Figure 1-6 In this structure, the material-turning and cooling structure is installed on top of the water-cooled base 1 and is mounted via a support frame 10. The support frame 10 is connected to the drive motor 17 via a fixed base 16. The output end of the drive motor 17 is connected to one end of the rotating shaft 18, and the other end of the rotating shaft 18 is connected to the storage tank 8 via a support base 19, providing stable support for the rotating shaft 18. The rotating shaft 18 is equipped with spiral blades 20. Driven by the drive motor 17, the spiral blades 20 can turn over or unload and convey the raw materials in the storage tank 8. At the same time, the rotating shaft 18 is equipped with a side support plate 21, and the side support plate 21 is equipped with a material-turning plate 22 that cooperates with the inner wall of the storage tank 8. The two sides of the material-turning plate 22 are symmetrically equipped with scraping arc surfaces. During the rotation process, the material-turning plate 22 can not only further turn over and stir the raw materials, but also use the scraping arc surfaces to scrape off the raw materials attached to the inner wall of the storage tank 8, ensuring the cleanliness of the inside of the storage tank 8 and improving the cooling effect.

[0035] The working principle of this utility model is as follows:

[0036] The pre-processed biomass fuel raw materials are placed into the storage tank 8. The water pump structure is turned on. The water in the pool enters the hollow structure of the water cooling base 1 through the water inlet pipe 3 under the action of the water pump. After circulating in the hollow structure to absorb the heat transferred from the storage tank 8, it flows back to the water pool through the return water pipe 4. The continuous circulation achieves the cooling of the storage tank 8 and creates a low-temperature environment for the raw materials to cool down.

[0037] Start the drive motor 17, which drives the rotating shaft 18 to rotate. The spiral blades 20 on the rotating shaft 18 rotate accordingly, turning and conveying the raw materials in the storage tank 8, causing the raw materials to move continuously within the storage tank 8. At the same time, the turning plate 22 on the side support plate 21 also rotates with the rotating shaft 18. The turning plate 22 further stirs the raw materials and uses the scraping arc surfaces on both sides to scrape off the raw materials adhering to the inner wall of the storage tank 8, ensuring that the raw materials are in full contact with the air and achieve uniform cooling.

[0038] Once the raw materials have cooled to the required processing conditions, the opening and closing cover 6 is opened. Under its own weight and guided by the discharge guide 7, the raw materials in the storage tank 8 are smoothly discharged from the discharge port 9 and transported to subsequent processing steps. During the unloading process, the opening degree of the opening and closing cover 6 can be controlled according to actual needs to adjust the unloading speed and quantity.

[0039] Throughout the cooling process, the shielding frame 12 is magnetically fixed to the magnetic plate 14 via the magnetic coupling strip 15. The breathable mesh 13 on it ensures air circulation and prevents external debris from entering the storage tank 8. When it is necessary to observe or operate the raw materials in the storage tank 8, the shielding frame 12 can be opened through the hinge structure 11, and then closed and fixed after the operation is completed.

[0040] The beneficial effects of this utility model are as follows: Utilizing the inverted conical platform structure, the material at the bottom is gathered, and then continuously transported and turned from bottom to top by an auger, so that the material is fully turned and the heat dissipation is more uniform and efficient; the water cooling method is environmentally friendly and stable, and with the continuous turning and stirring, the material can be fully and evenly attached to the inner wall of the water cooling base for heat exchange; the top protective shield does not hinder heat dissipation and can also shield and protect the material; the overall operation of the device is simple and highly automated.
