Description

Technical Field

[0001] This utility model relates to the field of rapeseed processing technology, specifically to a novel energy-saving rapeseed through-flow dryer. Background Technology

[0002] Rapeseed is one of China's major oilseed crops and honey-producing crops. Its seeds are one of the main raw materials for extracting oil. Most rapeseed oil production plants purchase rapeseed from farmers. However, the rapeseed harvested by farmers, especially freshly threshed wet seeds, usually has a high moisture content, generally between 12% and 18%, or even higher. A high-moisture environment is a breeding ground for molds such as aflatoxin and ochratoxin. At the same time, as a living plant seed, rapeseed continues to respire even after being separated from the plant, consuming its own oil and carbohydrates and releasing heat and water. In a high-moisture environment, rapeseed respiration is vigorous, which will continue to consume oil and may even cause germination or clumping, resulting in a decrease in subsequent oil yield.

[0003] In the existing technology, in order to prevent the above situation from occurring, rapeseed needs to be dried. Usually, the rapeseed is placed directly in a frame to dry naturally. Since the rapeseed is piled up together, it needs to be turned over to dry, which is quite troublesome. In addition, rapeseed loses water very slowly during the drying process, requires long-term exposure to sunlight, and has a long processing cycle and low efficiency.

[0004] Therefore, there is an urgent need for a drying device that can solve the problems of cumbersome turning and drying, slow water loss, long processing cycle and low efficiency of the existing natural drying method, so as to achieve efficient and uniform drying of rapeseed, while reducing oil consumption and ensuring subsequent oil yield. Utility Model Content

[0005] The present invention aims to provide a new type of energy-saving rapeseed through-flow dryer to solve the problems of troublesome turning and drying, slow water loss, long processing cycle and low efficiency of the existing natural drying method, so as to achieve efficient and uniform drying of rapeseed, while reducing oil consumption and ensuring subsequent oil yield.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: A novel energy-saving rapeseed through-flow dryer, comprising a drying frame and a conveyor belt disposed within the drying frame. The drying frame comprises multiple boxes assembled sequentially. Each box at both ends of the drying frame is provided with an inlet and an outlet. The inlet has a limiting claw at its front end along the conveyor belt's conveying direction, which does not contact the conveyor belt. Each box has an air inlet and an observation window on the same side. Furthermore, the air inlet is centrally located on the housing, and the observation window is at a greater height on the housing than the air inlet.

[0007] Furthermore, a suction hood is provided on the top of the box located in the middle of the drying frame, and the cross-section of the suction hood is trapezoidal.

[0008] Furthermore, each enclosure is equipped with four cleaning doors on the same side as the air inlet and the observation window. The four cleaning doors are arranged in two rows and two columns, with the air inlet and the first row of cleaning doors arranged in the same row. The size of the cleaning doors is larger than the size of the air inlet.

[0009] Furthermore, the spacing between the two rows of cleaning doors is the same as the spacing between the observation window and the first row of cleaning doors.

[0010] Furthermore, the length of the conveyor belt is less than the length of the drying frame, the input end of the conveyor belt faces the feed inlet, the output end of the conveyor belt faces the discharge outlet, and the output end of the conveyor belt is equipped with a drive device that can drive the conveyor belt.

[0011] The beneficial effects of this solution are as follows: By setting up a conveyor belt in conjunction with a drive device, continuous conveying of rapeseed from the inlet to the outlet is achieved, eliminating the need for frequent manual turning and significantly reducing labor intensity. Simultaneously, it improves the automation level of the drying process and adapts to batch processing needs. The limiting claws at the inlet can initially sort the rapeseed entering the conveyor belt, preventing excessive accumulation that could affect the drying effect and ensuring even spreading of the rapeseed during conveying. The centrally located air inlet on each box allows hot air to evenly enter the drying frame, fully contacting the rapeseed above the conveyor belt to create a through-flow drying effect, accelerating the dissipation of moisture from the rapeseed. The trapezoidal suction hood at the top of the middle box of the drying frame can quickly expel the hot and humid air generated during the drying process, forming good airflow circulation and further improving drying efficiency. Compared to natural drying methods, this device significantly shortens the processing cycle, and due to its rational airflow circulation and high heat utilization rate, it achieves energy-saving effects.

[0013] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: housing 1, feed inlet 11, discharge outlet 12, air inlet 13, observation window 14, cleaning door 15, conveyor belt 2, reducer 3, suction hood 4, transmission chain 5, limit claw 6. Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] Example 1 The basic implementation examples are as follows: Figure 1-2 As shown in the attached document Figure 1 and attached Figure 2 The diagram illustrates a novel energy-saving rapeseed through-flow dryer, comprising a drying frame and a conveyor belt 2 disposed within the drying frame. The drying frame is composed of multiple sequentially connected boxes 1. This modular structure allows for adjustment of the overall length of the drying frame according to actual drying needs, improving the equipment's versatility. The boxes 1 at both ends of the drying frame are respectively equipped with an inlet 11 and an outlet 12, both directly facing the conveyor belt 2 to ensure smooth rapeseed entry and exit.

[0017] The feed inlet 11 is provided with a limiting claw 6 at the front end along the conveying direction of the conveyor belt 2, which does not contact the conveyor belt 2. The limiting claw 6 is made of elastic material, and its spacing can be finely adjusted according to the size of the rapeseed particles. When the rapeseed enters the conveyor belt 2, it combs and flattens the rapeseed to avoid excessive accumulation and ensure uniform drying. In a preferred embodiment, the conveyor belt 2 can adopt a mesh structure to facilitate hot air penetration. The length of the conveyor belt 2 is less than the length of the drying frame, allowing the input and output ends of the conveyor belt 2 to extend outside the drying frame for easy connection with feeding and discharging equipment. The output end of the conveyor belt 2 is equipped with a drive device. In a preferred embodiment, the drive device specifically adopts a combination structure of a reducer 3 and a transmission chain 5. The reducer 3 can be a hardened cylindrical gear reducer 3, which has the characteristics of strong load-bearing capacity, high transmission efficiency, and stable operation. The output shaft of the reducer 3 is connected to the drive sprocket through a coupling. Driven sprockets are installed at both ends of the drive roller of the conveyor belt 2. The transmission chain 5 is wound between the drive sprocket and the driven sprocket, achieving stable power transmission through chain drive. This structure can precisely adjust the running speed of the conveyor belt 2 by adjusting the reduction ratio of the reducer 3 or by cooperating with a variable frequency motor (if variable frequency control is used), thereby precisely controlling the residence time of rapeseed in the drying frame to adapt to the drying requirements of rapeseed with different initial moisture contents.

[0018] Each chamber 1 has an air inlet 13 and an observation window 14 on the same side. The air inlet 13 is centrally located on the chamber 1 and is connected to a hot air generator. The hot air generator can use a heat pump for heating, which has a significant energy-saving effect. The centrally located air inlet 13 allows the hot air to be evenly diffused into the interior of the chamber 1. The observation window 14 is made of high-temperature resistant transparent glass and its height is greater than that of the air inlet 13, making it convenient for staff to observe the drying status of the rapeseed inside the chamber from different angles.

[0019] The top of the box 1 in the middle of the drying frame is equipped with a suction hood 4. The cross-section of the suction hood 4 is trapezoidal. The trapezoidal structure can increase the suction area and improve the efficiency of exhausting hot and humid air. The suction hood 4 is connected to the air-drawing device. The air-drawing device is linked with the hot air generator to ensure that a stable airflow circulation is formed in the drying frame.

[0020] Each housing 1 is also equipped with four cleaning doors 15. The four cleaning doors 15 are located on the same side as the air inlet 13 and the observation window 14, and are arranged in two rows and two columns. The air inlet 13 is arranged in the same row as the first row of cleaning doors 15. The size of the cleaning doors 15 is larger than that of the air inlet 13, which facilitates the cleaning of the air inlet 13 and the inner wall of the housing 1. The spacing between the two rows of cleaning doors 15 is the same as the spacing between the observation window 14 and the first row of cleaning doors 15, making the equipment structure layout more reasonable and the appearance neater.

[0021] The working principle of this utility model is as follows: In use, firstly, based on the initial moisture content of the rapeseed, the control system sets the running speed of the conveyor belt 2, the outlet temperature of the hot air generator, and the airflow of the induced draft device. Then, the rapeseed is fed into the conveyor belt 2 through the feed inlet 11, where the limiting claws 6 comb and flatten the rapeseed. The drive device is activated, with the reducer 3 providing stable power. Through the cooperation of the drive sprocket, transmission chain 5, and driven sprocket, the drive roller of the conveyor belt 2 rotates, thereby driving the conveyor belt 2 to run smoothly and transport the rapeseed to… Inside the drying frame, hot air generated by the hot air generator enters the drying frame evenly through the air inlet 13 on each box 1, penetrating the rapeseed layer on the conveyor belt 2 to dry the rapeseed. The humid and hot air generated during the drying process is discharged through the suction hood 4 at the top of the middle box 1 by the exhaust fan. Workers can observe the drying status of the rapeseed in real time through the observation window 14 on each box 1, and adjust the equipment parameters promptly if any abnormalities are found. The dried rapeseed is discharged from the discharge port 12 along with the conveyor belt 2, completing the drying process. After use, the cleaning door 15 on each box 1 can be opened to clean and maintain the inner wall of the box 1, the air inlet 13, and the conveyor belt 2 to ensure normal operation of the equipment next time.

[0022] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
