Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and in particular to a soybean flour raw material mixing and anti-clogging discharge device. Background Technology

[0002] In the processing and storage of soybean flour raw materials, the mixing and storage silo is a key piece of equipment, widely used for the temporary storage and uniform mixing of materials. However, in actual use, it has been found that as soybean flour raw materials accumulate, the material gradually compacts under gravity, especially in the area near the discharge port, where concentrated pressure and poor material flowability easily lead to agglomeration. This agglomeration not only reduces the material's flowability but can also cause partial or complete blockage of the discharge channel, affecting the normal operation of the equipment. Furthermore, soybean flour has a certain degree of hygroscopicity; if the ambient humidity is not properly controlled, the agglomeration problem will be further exacerbated, leading to poor discharge or even shutdown for cleaning, increasing maintenance costs and the risk of production interruption.

[0003] Therefore, a soybean flour raw material mixing and anti-clogging discharge device is proposed to solve the above-mentioned technical problems and improve the reliability and production efficiency of the equipment. Utility Model Content

[0004] In order to overcome the problems mentioned in the background art, the present invention provides a soybean flour raw material mixing and anti-clogging discharge device.

[0006] Preferably, there is a gap between the air guide pipe and the storage bin, and the air guide pipe is used to support the material in the storage bin.

[0007] Preferably, a baffle is fixedly connected inside the storage bin, and the baffle and the storage bin form an annular groove. The baffle is located above the air guide, and the air guide is located inside the annular groove.

[0008] Preferably, the centerline of the nozzle slopes downward from the air inlet to the air outlet, and a one-way valve is fixedly connected inside the nozzle.

[0009] Preferably, it further includes three sets of adjustment units distributed circumferentially at equal intervals. The adjustment units are disposed in adjacent air guide pipes and are used to control multiple nozzles to spray air intermittently.

[0010] The adjustment unit includes a rotating tube, which is rotatably disposed inside an adjacent air guide tube. The rotating tube has multiple guide holes, the number of which is the same as the number of nozzles on a single air guide tube. A drive motor is fixedly connected to the air guide component. The output shaft of the drive motor is fixedly connected to the adjacent rotating tube through a connector, and the connector connected to the output shaft of the drive motor is sealed and rotates with the air guide tube.

[0011] Preferably, the plurality of the guide holes are spirally distributed to control the plurality of nozzles on a single air guide pipe to spray air alternately.

[0014] The beneficial effects of this utility model are:

[0015] This invention guides gas from the nozzle through a gas guide component and a gas guide pipe. The ejected gas impacts and penetrates the agglomerated area, breaking down its internal binding structure, loosening the agglomerated soybean powder, restoring its fluidity, and ensuring continuous discharge of the soybean powder. By controlling the rotation of the rotating pipe, multiple nozzles sequentially spray gas from bottom to top, guiding the gas to blow and disturb the soybean powder in different parts. The gas injection can form an air film between the soybean powder particles, reducing the contact pressure and frictional resistance between particles, thereby improving fluidity and further assisting in the rapid discharge of the soybean powder. By moving the sliding sleeve to block part of the area of ​​adjacent guide holes, the gas velocity is increased, enhancing the impact of the ejected gas on the agglomerated material and ensuring the smooth discharge of the soybean powder.

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] refer to Figures 1-4 As shown, one embodiment of this utility model provides: a soybean flour raw material mixing anti-clogging discharge device, including a storage bin 1, a discharge unit 2 provided at the lower end of the storage bin 1, an air guide 3 installed inside the storage bin 1, three circumferentially equidistant air guide pipes 4 fixedly connected and connected to the air guide 3, and multiple evenly distributed nozzles 5 fixedly connected and connected to the air guide pipes 4; there is a gap between the air guide pipes 4 and the storage bin 1, and the air guide pipes 4 are used to support the material inside the storage bin 1; a baffle 6 is fixedly connected inside the storage bin 1, and the baffle 6 and the storage bin 1 form an annular groove, the baffle 6 is located above the air guide 3, and the air guide 3 is located inside the annular groove; the center line of the nozzle 5 is inclined downward from the air inlet end to the air outlet end, and a one-way valve 7 is fixedly connected inside the nozzle 5.

[0025] The above setup allows for the following: Storage silo 1 is equipped with a control terminal (not shown in the existing equipment diagram). The lower part of storage silo 1 is the discharge port. Discharge unit 2 is used to block or open the discharge port of storage silo 1. Air guide pipe 4 supports the material, reducing material clumping between the air guide pipe 4 and storage silo 1, facilitating material discharge and reducing bridging within storage silo 1, thus ensuring smooth material flow and discharge. Each air guide pipe 4 has three nozzles 5 (the number shown in the attached diagram; the actual number can be set according to requirements). The tilt direction of the nozzles 5 and the installation of the one-way valve 7 are used to prevent soybean powder from entering the air guide pipe 4. Before discharging, an external air pump (not shown in the existing equipment diagram) is connected to the air guide component 3, and the external air pump is electrically connected to the control terminal. (Reference) Figure 2 , Figure 4 and Figure 5As shown, it also includes three sets of adjustment units circumferentially distributed. The adjustment units are set in adjacent air guide pipes 4 and are used to control multiple nozzles 5 to spray intermittently. The adjustment unit includes a rotating pipe 8, which is rotatably set in adjacent air guide pipes 4. Multiple guide holes 9 are opened on the rotating pipe 8. The number of guide holes 9 is the same as the number of nozzles 5 on a single air guide pipe 4. A drive motor 10 is fixedly connected to the air guide component 3. The output shaft of the drive motor 10 is fixedly connected to the adjacent rotating pipe 8 through a connector, and the connector connected to the output shaft of the drive motor 10 is sealed to rotate with the air guide pipe 4. The multiple guide holes 9 are spirally distributed and are used to control multiple nozzles 5 on a single air guide pipe 4 to spray alternately.

[0026] The above configuration enables each rotating tube 8 to have three guide holes 9, which are spirally distributed on the outer side of the rotating tube 8. This allows the rotating tube 8 to rotate at different angles so that the guide holes 9 at different heights can connect with the adjacent nozzles 5, guiding the gas to impact the material at a specified height and ensuring the smoothness of the material discharge process. The drive motor 10 is electrically connected to the control terminal.

[0027] refer to Figure 5 and Figure 6 As shown, it also includes three sets of pressure regulating units distributed circumferentially at equal intervals. The pressure regulating units are set in adjacent rotating tubes 8 and are used to change the pressure in adjacent rotating tubes 8. The pressure regulating unit includes a sliding plate 11, which is slidably set in adjacent rotating tubes 8. A spring 12 is fixed between the sliding plate 11 and the adjacent rotating tube 8. Two connecting rods 13 are fixedly connected to the sliding plate 11. Multiple sliding sleeves 14 are slidably set in the rotating tube 8. The sliding sleeves 14 are fixedly connected to the adjacent connecting rods 13 and are used to change the size of the flow cross section of the adjacent guide hole 9.

[0028] The above setup enables the following: when the flowing gas cannot break up the agglomerated material in time, the agglomerated material continuously obstructs the ejected gas. At the same time, the external air pump continuously injects gas into the air guide 3. The gas pressure in the air guide 3 and the air guide pipe 4 increases step by step. The increased gas pressure will squeeze the sliding plate 11 to move. The movement of the sliding plate 11 drives the sliding sleeve 14 to move through the connecting rod 13. The movement of the sliding sleeve 14 gradually blocks the guide hole 9, making the flow cross section of the guide hole 9 smaller. As a result, the gas ejected from the guide hole 9 becomes faster. The high-speed flowing gas impacts the agglomerated material, increasing the breaking strength and ensuring that the material is discharged. The automatic increase in gas velocity during this process can prevent the material from flying around due to the initial gas velocity being too fast. Working principle: In the initial state, the bottommost guide hole 9 is connected to the bottommost nozzle 5. When it is necessary to discharge soybean powder, the operator opens the discharge unit 2 and starts the external air pump through the control terminal. Under the action of gravity, the soybean powder in the storage bin 1 falls downward, and the external air pump injects gas (the gas type can be selected according to the needs; dry gas can be selected for soybean powder) into the air guide 3, the three air guide pipes 4, and the three rotating pipes 8. Then, the gas squeezes the one-way valve 7 in the bottommost nozzle 5 through the bottommost guide hole 9, so that the gas is sprayed out from the three bottommost nozzles 5. The sprayed gas blows the soybean powder downward, preventing the material from blocking the discharge port.

[0029] During the gas flow process, the control terminal controls the three drive motors 10 to work at predetermined intervals. The drive motors 10 drive the adjacent rotating tubes 8 to rotate by a specified angle through the connecting parts, so that the guide hole 9 in the middle is connected to the nozzle 5 in the middle. At this time, the gas is guided to be ejected from the nozzle 5 in the middle, so that the gas impacts the material near the nozzle 5 in the middle. Then, the drive motors 10 are restarted to control the gas to be ejected from the nozzle 5 in the uppermost position. During this process, the gas is ejected downward and the material is guided to move downward at the same time, which improves the discharge rate to a certain extent.

[0030] When the material in the storage bin 1 clumps and blocks the nozzle 5, during the process of gas being ejected from the nozzle 5, if the initial gas cannot break up the clumped material, the gas pressure in the gas guide 3 increases due to the obstruction of the clumped material. The increased gas pressure then compresses the sliding plate 11 to move. The movement of the sliding plate 11 repeats the above operation of increasing the flow rate of the ejected gas, causing the high-speed flowing gas to impact the clumped material, increasing the breaking strength, thereby ensuring the material is discharged.

[0031] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
