Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a multi-stage cyclone grading and discharging system for drying soybean flour. Background Technology

[0002] During the drying process of soybean flour, uneven particle size distribution affects product quality. Therefore, a multi-stage cyclone grading and discharge system for soybean flour drying is established to perform gradient separation of soybean flour with different particle sizes. This system can accurately control the particle size distribution of the discharged material, improve the recovery rate of fine powder, and thus achieve efficient grading and continuous discharge of the dried material, meeting the needs of refined production of soybean flour products in food processing.

[0003] Chinese patent CN213051533U discloses a parallel vertical airflow classifier, comprising four flow dividers with identical structures arranged in parallel vertically. Each flow divider has a feed inlet at its lower end and an output outlet at its upper end on the side furthest from the feed inlet. The feed inlets and output outlets of two flow dividers are connected by connecting pipes. An air supply port is located at the bottom of each flow divider, and an air supply mechanism connected to the air supply port is also located at the bottom of the flow divider. The output end of the flow divider is connected to the input end of the top of a high-temperature bag filter via an air duct, and the output end of the high-temperature bag filter is connected to the input end of the top of a dust collector via an air duct. In this invention, the four parallel vertically arranged flow dividers achieve multi-stage airflow classification, and the air supply mechanism ensures sufficient airflow to the multi-stage flow dividers, improving the quality of multi-stage airflow classification and filtering the supply airflow.

[0004] The above-mentioned patent still has the following shortcomings: During the process of classifying soybean flour, the device needs to maintain a high air pressure inside, and the device needs to be opened when discharging, which causes the air pressure inside the device to drop sharply, destroying the stability of the classifying airflow field, greatly reducing the classifying efficiency of soybean flour particles, and even causing the phenomenon of mixing of coarse and fine powder. Therefore, it is necessary to stop the machine to discharge the material, which affects the continuity of soybean flour drying and classification. Utility Model Content

[0005] This invention provides a multi-stage cyclone grading and discharge system for drying soybean flour, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a multi-stage cyclone grading and discharging system for drying soybean flour, including a fixed frame, and further comprising:

[0008] A separation chamber is fixed to the top of a fixed frame, and a storage chamber is installed at the bottom of the separation chamber, with a discharge pipe fixed at the bottom of the storage chamber.

[0009] A servo motor is installed at the top of the separation chamber, and a grading blade is installed at the end of the output shaft of the servo motor. A guide plate is fixed at the bottom end of the grading blade.

[0010] The cleaning structure, located at the bottom of the guide plate, is used to agitate the soybean powder inside the storage compartment.

[0011] The discharge structure is disposed inside the discharge pipe. The discharge structure includes a rotating shaft rotatably connected inside the discharge pipe, a baffle fixed to the outside of the rotating shaft, a mounting ring fixed to the outside of the baffle, a rubber retaining ring sleeved on the outside of the mounting ring, and a transmission assembly disposed at the top of the mounting ring.

[0012] Using the above technical solution, soybean powder is fed into the separation chamber, and the introduced airflow drives the soybean powder to move upward. The grading blades driven by the servo motor cause the soybean powder particles to be initially graded under the combined action of centrifugal force and airflow drag. Fine soybean powder particles are discharged through the fine powder tube with the airflow, while coarse particles fall into the storage chamber under the action of gravity.

[0013] Furthermore, a feed pipe is installed at the bottom of one side of the fixed frame, and an air guide plate connected to the fixed frame is sleeved on the outside of the feed pipe. An air inlet pipe is installed on one side of the fixed frame, and a fine powder pipe is fixed at the top of one side of the fixed frame, with a connecting pipe installed on one side of the fine powder pipe.

[0014] Through the above technical solution, the air guide plate guides the airflow tangentially into the separation chamber, forming a rotating airflow field, which provides centrifugal grading power for soybean flour. The fine powder pipe is connected to the connecting pipe, so that the fine soybean flour particles are discharged with the airflow.

[0015] Furthermore, the transmission assembly includes an electromagnet installed inside the mounting ring, a connecting ring disposed at the bottom of the cleaning structure, an iron block installed inside the bottom of the connecting ring, a rubber sheet installed at the bottom of the connecting ring, and a conductive slip ring installed on one side of the rotating shaft.

[0016] The above technical solution uses an electromagnet to generate magnetic force and connect with the iron block, causing the connecting ring to rotate together with the mounting ring. This causes the baffle to push the soybean powder out, and at the same time, the baffle's rotation blocks the airflow inside and outside the discharge pipe, maintaining stable air pressure inside the system and ensuring that the grading process is not affected.

[0017] Furthermore, the diameter of the mounting ring is larger than the diameter of the connecting ring, and the electromagnet forms a magnetic connection with the iron block after being energized.

[0018] Through the above technical solution, the diameter difference enables a reasonable transmission ratio between the mounting ring and the connecting ring, while the magnetic connection between the electromagnet and the iron block provides power connection for the bevel gear transmission, ensuring that the mounting ring rotates synchronously with the connecting ring.

[0019] Furthermore, the baffle and the mounting ring are welded together as a single unit, and the baffles are arranged in a ring with equal spacing inside the mounting ring.

[0020] The above technical solution integrates the baffle and the mounting ring into a single structure, which enhances the overall strength and rigidity of the emission structure and prevents the emission function from being affected by the baffle loosening during long-term use. The baffles arranged in a ring at equal intervals can form a uniformly distributed blocking surface inside the emission pipe.

[0021] Furthermore, the cleaning structure includes a support frame fixed at the bottom of the separation chamber, a reducer installed at the top of the support frame, a connecting rod installed at the end of the reducer input shaft and connected to the guide plate, a drive shaft installed at the end of the reducer output shaft and connected to the connecting ring, and a scraper fixed on the outside of the drive shaft.

[0022] The above technical solution uses a guide plate that drives a reducer via a connecting rod, which in turn drives a scraper to clean the inner wall of the storage chamber and simultaneously agitate the soybean flour inside.

[0023] Furthermore, the scraper has a spiral structure, and the scraper is arranged in a ring with equal spacing on the outside of the drive shaft.

[0024] Through the above technical solution, the spiral scraper can generate axial thrust when rotating, pushing the soybean powder downward along the inner wall of the storage chamber. The circular and equally spaced arrangement ensures that there are no dead corners in the cleaning, effectively scraping off residual soybean powder and preventing soybean powder from clumping and accumulating.

[0025] The above-described solution of this utility model has at least the following beneficial effects:

[0026] This invention utilizes an electromagnet to generate magnetic force and connect magnetically with an iron block, causing the connecting ring to rotate along with the mounting ring. Simultaneously, a baffle plate blocks the flow of air inside and outside the discharge pipe while simultaneously discharging the soybean powder. This achieves the sealed discharge function of the device, facilitating the blocking of air flow during discharge and effectively maintaining stable air pressure within the device. Therefore, frequent start-ups and shutdowns are unnecessary, ensuring the continuity of the drying and grading process and reducing energy consumption and maintenance costs.

[0027] This invention uses a guide plate to drive a reducer via a connecting rod, which in turn drives a scraper to clean the inner wall of the storage chamber. At the same time, it agitates the soybean powder inside the storage chamber, thus achieving the inner wall cleaning function of the device. This can promptly remove residual soybean powder, preventing long-term adhesion of materials that could lead to deterioration or cross-contamination, and also preventing residual soybean powder from clumping and clogging the equipment.

[0035] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] like Figures 1 to 5 As shown, an embodiment of this utility model provides a multi-stage cyclone grading and discharging system for drying soybean flour, including a fixed frame 1, and further comprising:

[0037] The separation chamber 5 is fixed to the top of the fixing frame 1, and the bottom of the separation chamber 5 is equipped with a storage chamber 3, and the bottom of the storage chamber 3 is fixed with a discharge pipe 2.

[0038] Servo motor 6 is installed at the top of separation chamber 5, and a grading blade 12 is installed at the end of the output shaft of servo motor 6, and a guide plate 13 is fixed at the bottom of the grading blade 12.

[0039] The cleaning structure 7 is located at the bottom of the guide plate 13 and is used to turn the soybean powder inside the storage compartment 3.

[0040] The discharge structure 9 is disposed inside the discharge pipe 2. The discharge structure 9 includes a rotating shaft 905 rotatably connected inside the discharge pipe 2, a baffle 901 fixed to the outside of the rotating shaft 905, a mounting ring 903 fixed to the outside of the baffle 901, a rubber retaining ring 902 sleeved on the outside of the mounting ring 903, and a transmission assembly disposed at the top of the mounting ring 903.

[0041] A feed pipe 4 is installed at the bottom of one side of the fixed frame 1. An air guide plate 14 connected to the fixed frame 1 is sleeved on the outside of the feed pipe 4. An air inlet pipe 10 is installed on one side of the fixed frame 1. A fine powder pipe 11 is fixed at the top of one side of the fixed frame 1, and a connecting pipe 8 is installed on one side of the fine powder pipe 11.

[0042] In this embodiment of the invention, firstly, the soybean powder mixed with air is fed into the separation chamber 5 through the feed pipe 4. At the same time, the airflow introduced by the air inlet pipe 10 forms an upward airflow under the guidance of the air guide plate 14, which drives the soybean powder to move upward. The servo motor 6 is started to drive the grading blades 12 to rotate, generating a centrifugal force field. Under the combined action of centrifugal force and airflow drag, the soybean powder particles are initially graded. Fine soybean powder particles are discharged through the fine powder pipe 11 with the airflow, while coarse particles fall into the storage chamber 3 under the action of gravity. The soybean powder is graded by passing through multiple sets of separation chambers 5 in sequence with the air carrying soybean powder.

[0043] like Figures 1 to 5 As shown, the transmission assembly includes an electromagnet 907 installed inside the mounting ring 903, a connecting ring 906 located at the bottom of the cleaning structure 7, an iron block 908 installed inside the bottom of the connecting ring 906, a rubber sheet 909 installed at the bottom of the connecting ring 906, and a conductive slip ring 904 installed on one side of the rotating shaft 905. The diameter of the mounting ring 903 is larger than the diameter of the connecting ring 906. When the electromagnet 907 is energized, it forms a magnetic connection with the iron block 908. The baffle 901 and the mounting ring 903 are welded together as an integral structure, and the baffle 901 is arranged in a ring with equal spacing inside the mounting ring 903.

[0044] In this embodiment of the invention, when soybean powder needs to be discharged, the electromagnet 907 is energized through the conductive slip ring 904, causing the electromagnet 907 to generate magnetic force. Simultaneously, through the magnetic connection between the electromagnet 907 and the iron block 908, the connecting ring 906 drives the mounting ring 903 to rotate together. At the same time, the mounting ring 903 drives the baffle 901 to rotate, causing the baffle 901 to push the soybean powder out. During the rotation of the baffle 901, a simple airtight chamber is formed between the adjacent baffles 901 and the discharge pipe 2, blocking the airflow inside and outside the discharge pipe 2. The rubber baffle ring 902 and the rubber sheet 909 prevent the electromagnet 907, the iron block 908 from contacting the soybean powder. After the discharge is completed, the power supply to the electromagnet 907 is disconnected, the magnetic connection disappears, the baffle 901 stops rotating, blocking the airflow inside and outside the device, maintaining the stability of the internal air pressure of the system, and ensuring that the grading process is not affected.

[0045] like Figures 1 to 4 As shown, the cleaning structure 7 includes a support frame 702 fixed inside the bottom of the separation chamber 5, a reducer 701 installed on the top of the support frame 702, a connecting rod 705 installed on the end of the input shaft of the reducer 701 and connected to the guide plate 13, a drive shaft 703 installed on the end of the output shaft of the reducer 701 and connected to the connecting ring 906, and a scraper 704 fixed on the outside of the drive shaft 703. The scraper 704 has a spiral structure and is arranged in a ring at equal intervals on the outside of the drive shaft 703.

[0046] In this embodiment of the utility model, when the guide plate 13 rotates, it drives the input shaft of the reducer 701 to rotate through the connecting rod 705. Then, after being decelerated by the reducer 701, the reducer 701 drives the transmission shaft 703 to rotate, so that the scraper 704 on the outside of the transmission shaft 703 cleans the inner wall of the storage chamber 3, scrapes off the soybean powder remaining on the inner wall, and prevents the soybean powder from adhering for a long time, which may cause deterioration or affect the performance of the equipment. At the same time, the scraper 704 can stir the soybean powder in the storage chamber 3 to prevent clumping and promote the uniform distribution of soybean powder and subsequent discharge.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
