Description

Technical Field

[0001] The utility model relates to a grain drying technology, in particular to grain microwave drying equipment with uniform heating. Background Art

[0002] Microwave drying equipment, also known as a microwave dryer, is used to dry food, medicinal herbs, wood, building materials, cardboard, and other materials. Compared to traditional drying equipment, microwave drying equipment features faster drying speeds, higher efficiency, and is environmentally friendly and energy-efficient, making it a new type of equipment embracing the low-carbon economy. Its operating principle is to utilize the penetrating heating properties of microwaves to raise the temperature of the material, vaporizing and evaporating the moisture within. The evaporated water vapor is then removed through a dehumidification system, drying the material. Microwave drying equipment is therefore essential in the production and processing of grains.

[0003] Existing microwave drying equipment usually dries grain by pouring it onto a conveyor belt and flattening it before feeding it into the equipment for microwave drying. During the pouring process, in order to avoid grain accumulation and affecting the uniform heating of grain at different positions, the bottom end of the guide rack is usually set at a low distance from the conveyor belt to prevent the grain from piling up too high after falling on the conveyor belt. However, due to the different particle sizes of grain, the bottom end of the guide rack cannot be set too low from the conveyor belt. As a result, when pouring and drying some grains with smaller particle sizes, some accumulation is inevitable, resulting in uneven heating during the grain drying process and affecting the heating effect. Therefore, we propose a grain microwave drying equipment with uniform heating to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 5 As shown, a microwave drying device for grains with uniform heating comprises a microwave drying device 1, a conveying structure 2 is provided on the microwave drying device 1, a fixing frame 3 is provided on the conveying structure 2; a material discharge assembly, the material discharge assembly comprises a guide frame 4 fixedly connected to the fixing frame 3, the guide frame 4 is composed of an inclined section 41 and a vertical section 42, the bottom front and back sides of the inclined section 41 are respectively fixedly connected with a protrusion 5, a through groove 6 is provided at the connection between the inclined section 41 and the vertical section 42, and a sliding connection is formed in the through groove 6. There is a guide plate 7, and grooves 8 are respectively provided on the front and rear sides of the top of the guide plate 7. The bottom of the guide plate 7 is fixedly connected to a ring tube 9, and the inner side of the ring tube 9 is threadedly connected to the extrusion disk 10. The bottom of the guide plate 7 is slidably connected to the baffle 12. A square groove 13 is also provided on the left side of the bottom of the guide plate 7. The top of the square groove 13 is rotatably connected to the screw 14. The bottom of the square groove 13 is fixedly connected to a sealing plate 15. The left side of the baffle 12 is fixedly connected to a convex plate 16, and the convex plate 16 is threadedly connected to the outside of the screw 14.

[0022] It should be noted that the fixing frame 3 is used to fix the guide frame 4, the inclined section 41 on the guide frame 4 is used to make the grain fall along the slope under the action of gravity, the vertical section 42 is used to limit the falling speed of the grain, the protrusion 5 and the groove 8 are used to guide the guide plate 7 to slide on the guide frame 4, the through groove 6 is used to allow the guide plate 7 to pass, the annular tube 9 is used to install the extrusion plate 10, and the extrusion plate 10 is used to fix the guide plate 7 at the current position when the guide plate 7 is slid to the appropriate position. The baffle 12 is used to limit the maximum stacking height of the grain after it falls on the conveying structure 2. The square groove 13 is used to install the screw 14 and the convex plate 1 6, the sealing plate 15 is used to support the outer side of the bottom end of the screw 14 to prevent the screw 14 from tilting, and the convex plate 16 is used to cooperate with the rotation of the screw 14 to drive the baffle 12 to rise and fall as a whole. Through the provided discharge component, the internal width of the vertical section 42 of the guide frame 4 can be adjusted, and the distance between the baffle 12 and the conveying structure 2 can also be adjusted to meet the heating and drying requirements of different types of grains or grains of the same type with different particle sizes. The problem of grain accumulation on the conveying structure 2 can be avoided according to different situations, and uniform heating of grains of different sizes can be fully achieved, thereby improving the heating and drying effect of the equipment.

[0023] The guide frame 4 is a split structure, which is composed of two identical parts. The split manufacturing of the guide frame 4 can facilitate the confinement of the guide plate 7 to the inner side of the groove 6 when it is combined, which facilitates the installation of the guide plate 7.

[0024] The outer contour of the bump 5 is adapted to the inner cross section of the groove 8. The front and rear side surfaces of the bump 5 are both inclined surfaces. By setting them as inclined surfaces, the separation of the bump 5 and the groove 8 can be avoided, thereby improving the stability of the bump 5 in guiding the guide plate 7.

[0025] A bending section is provided at the left end of the guide plate 7. When the rightmost end face of the guide plate 7 is in contact with the inner surface of the vertical section 42 of the guide frame 4, the groove 8 does not contact the protrusion 5. The bending section makes it easy for the user to manually pull the guide plate 7 to move, making it convenient for the user to operate.

[0026] The bottom of the screw rod 14 is fixedly connected with a ball head 11 , the diameter of which is larger than the maximum outer diameter of the screw rod 14 . Adding the ball head 11 component can make it easier for the user to rotate the screw rod 14 , thus facilitating operation.

[0027] The utility model is specifically implemented as follows: when a batch of grains needs to be dried, the external dimensions of the grains are first measured, and the distance between the baffle 12 and the conveying structure 2 and the internal width of the vertical section 42 on the guide frame 4 are adjusted according to the maximum external dimensions. When adjusting the internal width of the vertical section 42, the extrusion plate 10 is first rotated so that one end thereof no longer contacts the surface of the inclined section 41 of the guide frame 4 through the threaded engagement between the remaining annular tubes 9. The user pulls the bent section to drive the guide plate 7 to move, and changes the distance between the inner wall of the guide frame 4 on one side of the guide plate 7 and the inner wall of the guide frame 4 on the other side to a suitable size. The extrusion plate 10 is small, and then the extrusion plate 10 is rotated in the opposite direction so that one end of it contacts and squeezes the surface of the inclined section 41 of the guide frame 4 again. When it is necessary to adjust the surface distance between the baffle 12 and the conveying structure 2, the ball head 11 is rotated to drive the screw 14 to rotate, and the baffle 12 is driven to rise and fall through the threaded cooperation between the screw 14 and the convex plate 16 until its bottom end is at a suitable height, completing the adjustment operation. Thereafter, the grain to be dried is poured from the top of the guide frame 4, so that the grain falls onto the conveying structure 2 through the guide frame 4, and is moved to the microwave drying equipment 1 for drying.
