Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rapeseed, in particular to a rapeseed drying device. Background Art
[0002] Rapeseed, also known as rapeseed oil, is an important oil crop, mainly used to extract edible oil and industrial oil. Rapeseed oil is rich in unsaturated fatty acids, especially linoleic acid, which is beneficial to human health. In addition, rapeseed can also be used to make industrial products such as biodiesel. During the processing of rapeseed, a drying device is needed to dry the powder and water in the rapeseed for subsequent processing operations.
[0003] Drum dryer is a commonly used equipment for drying rapeseed. Usually, a heating device is used at one end of the drum to transfer heat into the drum to dry the rapeseed. However, rapeseed contains moisture, which causes the moisture in the rapeseed to evaporate and drift in the drum during the drying process. In order to dissipate the water vapor in the drum, the other end of the drum is usually an open structure. As a result, a large amount of heat will be lost when the water vapor drifts to the outside of the drum, thereby increasing energy consumption. Utility Model Content
[0004] The purpose of the utility model is to provide a rapeseed drying device to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A tank for storing water;
[0008] The drum is rotated between two side surfaces of the box body that are separated from each other, and is used to roll the rapeseed. A heating wire is embedded and fixed on the inner wall of the drum. Both ends of the drum are rotatably connected with barrel covers. A metal pipe that is fixed to the box body is fixed on one side of the barrel cover. The metal pipe located inside the box body is a coil structure and is wound around the outer wall of the drum. A plurality of air outlets are opened on the top surface of the box body. A feed pipe is fixed on one side of the barrel cover. A sealing plate is hinged at one end of the outer wall of the drum.

[0020] 1. The heat generated by the energization of the heating wire can dry the rapeseed in the drum, and then the water vapor generated during the drying process of the rapeseed is introduced into the water inside the box body through the metal pipe, so that the water temperature rises rapidly and then is transmitted to the drum again, thereby reducing the heat loss in the drum, improving the drying efficiency, and reducing the energy consumption;
[0021] 2. Driven by the motor two and with the action of the four springs, the housing can reciprocate inside the drum.

Specific implementation manners
[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0029] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a rapeseed drying device includes a box body 1 for storing water, a drum 2 rotatably penetrating between the opposite side surfaces of the box body 1 for tumbling rapeseed. Heating wires are fixedly embedded in the inner wall of the drum 2. Bucket covers 21 are rotatably connected to both ends of the drum 2. A metal pipe 22 fixedly penetrating through the box body 1 is fixedly penetrated through one side surface of one of the bucket covers 21. The metal pipe 22 located inside the box body 1 is a coiled pipe structure and is wound around the outer wall of the drum 2. A plurality of air outlet holes 11 are penetrated through the top surface of the box body 1. A feed pipe 24 is fixedly penetrated through one side surface of one of the bucket covers 21. A sealing plate 23 is hinged to one end of the outer wall of the drum 2. A vibration mechanism 3 is arranged inside the drum 2 for evenly scattering rapeseed.
[0030] Specifically, first, a certain amount of water is poured into the interior of the box body 1, such that the water surface submerges the bottom end of the outer wall of the drum 2 (but the water surface should be lower than the axis of the drum 2). Then, the sealing plate 23 is fixed to the drum 2 through a buckle. Next, rapeseeds are poured into the interior of the drum 2 through the feed pipe 24. By energizing the heating wire, heat can be released to dry the rapeseeds inside the drum 2. At the same time, the rotation of the drum 2 enables the rapeseeds to tumble inside the drum 2. A part of the tumbling rapeseeds will fall into the interior of the vibration mechanism 3. Through the operation of the vibration mechanism 3, the rapeseeds can be evenly scattered, facilitating the rapid drying of the rapeseeds. Since during the drying process of the rapeseeds, the moisture in the rapeseeds dissipates inside the drum 2 under the action of the heat released by the heating wire, and as the moisture released by the rapeseeds increases, the pressure inside the drum 2 increases. As a result, the moisture inside the drum 2 can be transported to the interior of the box body 1 through the metal pipe 22. Since the water poured into the box body 1 contains a large amount of heat, it will quickly liquefy when encountering water and transfer the heat to the water. Moreover, a part of the heat released by the heating wire will be transferred to the water through the drum 2, causing the temperature of the water to rise rapidly. Since the specific heat capacity of water is relatively high, water has a good heat storage effect. The heat stored in the water will be transferred to the drum 2 again, preventing the temperature inside the drum 2 from dropping rapidly. Therefore, the energy consumption of the heating wire can be reduced (since at the beginning, water will absorb a large amount of heat, and the time required for drying the first batch of rapeseeds is relatively long. However, when the water temperature rises, the drying efficiency of the subsequent rapeseeds will increase).
[0031] Embodiment 1
[0032] As Figure 3 and Figure 4 shown, in this embodiment, one end of the top surface of the box body 1 is fixedly connected with a first motor 12. The output end of the first motor 12 is fixedly connected with a gear 13. One end of the outer wall of the drum 2 is fixedly connected with a gear ring 27 that meshes with the gear 13. The inner wall of the drum 2 is fixedly connected with a plurality of stirring plates 25 at equal angles in a ring shape. Two symmetric fixing members 26 are fixedly connected between the barrel cover 21 and the box body 1. Fixed blocks 14 are fixedly connected to the two opposite side surfaces of the box body 1 and away from the sealing plate 23. The bottom surface of the fixed block 14 is fixedly connected with a fixed seat, and a hydraulic cylinder 15 is rotatably connected inside the fixed seat.
[0033] In this embodiment, the driving of the first motor 12 enables the gear 13 to drive the gear ring 27 to rotate. The rotating gear ring 27 enables the drum 2 to rotate inside the box body 1. The rotating drum 2 can make the rapeseeds tumble inside the drum 2 through a plurality of stirring plates 25, facilitating the rapid drying of the rapeseeds. When the rapeseeds are completely dried, the start of the two hydraulic cylinders 15 causes the box body 1 to drive the drum 2 to tilt. Then, the sealing plate 23 is opened. At the same time, through the continuous rotation of the drum 2, the dried rapeseeds inside the drum 2 can be poured out.
[0034] Embodiment 2
[0035] As Figure 5 shown, in this embodiment, the vibration mechanism 3 includes a housing 31 disposed inside the drum 2, and the top surface of the housing 31 is an open structure, and the inner bottom surface of the housing 31 is a mesh structure. Two symmetric slide bars are fixedly connected between the two barrel covers 21 and penetrate and slide through the top end of the housing 31. Four springs 32 are sleeved on the outer walls of the corresponding slide bars and are fixedly connected between the housing 31 and the corresponding barrel cover 21. Two symmetric L-shaped plates 16 are fixedly connected to the bottom end of one side surface of the box body 1. One side surface of the housing 31 is fixedly connected with an L-shaped plate 33 that penetrates and slides through the corresponding barrel cover 21 and the box body 1. A rotating shaft is rotatably connected between the two L-shaped plates 16, and a cam 34 is fixedly connected to the outer wall of the rotating shaft. A motor 2 35 is fixedly connected to one side surface of one of the L-shaped plates 16. The output end of the motor 2 35 penetrates through the corresponding L-shaped plate 16 and is fixedly connected to the rotating shaft. A baffle 36 is fixedly connected to the bottom surface of the housing 31.
[0036] In this embodiment, the rotation of the cam 34 can be driven by the motor 2 35, and the rotating cam 34 can move the housing 31 in the drum 2. At the same time, due to the action of the four springs 32, the housing 31 can reciprocate in the drum 2 (similar to the sieve principle). Since part of the rapeseed will enter the inside of the housing 31 under the action of the drum 2 and the multiple stirring plates 25, and then evenly fall to the bottom of the drum 2 under the reciprocating movement of the housing 31, the rapeseed can be evenly and quickly dried.
