Summary of the Invention

[0003] The utility model provides a structure for evenly spreading solid particles for steaming. Through structure optimization and adapting to different process parameters, etc., it realizes continuous, even and continuous spreading of the steaming material to improve the quality and efficiency of steaming.

[0004] To solve the above problems, a structure for evenly spreading solid particles for steaming is proposed, including an annular bearing structure. The inner side of the bearing structure has a circular sieve. The outer surface of the lower side of the sieve is fixed with an annular connecting base. At least three driving motors are fixedly distributed along the circumference of the bearing structure. The output shaft of the driving motor is connected to the connecting base through an eccentric shaft of the same model.

[0005] In the above-mentioned spreading structure, the bearing structure is an annular structure with a certain height, and its height is greater than the length of the driving motor. The lower end of the bearing structure is provided with motor holes distributed along the circumference. The driving motors are all fixed in the motor holes, and the output shaft of the driving motor extends downward to the outside of the bearing structure;

[0006] In the above-mentioned spreading structure, the height of the sieve is greater than the height of the bearing structure. The upper end of the sieve is flush with the upper end of the bearing structure. The lower end of the sieve extends to the lower side of the bearing structure. The connecting base is located directly below the bearing structure.

[0007] In the above-mentioned spreading structure, there are four driving motors in total, which are distributed at the four corners of a square. The sieve makes a circular motion under the synchronous action of the four driving motors;

[0008] In the above-mentioned spreading structure, the eccentric shaft is an eccentric coupling.

[0009] Compared with the prior art, the utility model can improve the sieve in a limited compact space so that the retort material can be evenly spread into the retort barrel. Through structural optimization, it can adapt to different process parameters and achieve even and continuous spreading of the retort material, so as to improve the quality and efficiency of retorting, and is suitable for popularization and application.

[0016] Example

[0017] Refer to the attached Figures 1 to 5 This embodiment is aimed at improving the solid particle uniform spreading device for the upper retort, and specifically includes an annular bearing structure 1, the inner side of the bearing structure 1 is provided with a circular sieve 2, the outer surface of the lower side of the sieve 2 is fixed with an annular connecting base 3, four driving motors 4 are fixed along the circumferential direction on the bearing structure 1, and the driving motors 4 are distributed in the four corners of a square, and the output shaft 41 of the driving motor 4 is connected to the connecting base 3 through an eccentric shaft 5 of the same type, and the eccentric shaft 5 is an eccentric coupling.

[0018] The supporting structure 1 is an annular structure with a certain height, and its height is greater than the length of the driving motor 4. The lower end of the supporting structure 1 is provided with motor holes distributed along the circumferential direction. The driving motors 4 are all fixed in the motor holes. The output shaft 41 of the driving motor 4 extends downward to the outside of the supporting structure 1. The height of the sieve 2 is greater than the height of the supporting structure 1. The upper end of the sieve 2 is flush with the upper end of the supporting structure 1, and the lower end of the sieve 2 extends to the lower side of the supporting structure 1. The connecting base 3 is located directly below the supporting structure 1.

[0019] The load-bearing structure 1 consists of annular upper and lower cover plates arranged in parallel, an inner cylinder structure that connects and fixes the annular upper and lower cover plates inside, and an outer cylinder structure 6 (the protective shell of the load-bearing structure 1) that connects and fixes the annular upper and lower cover plates outside.

[0020] Figure 3 The plane simplified model of this structure, the main power of this structure comes from four driving motors 4. The geometric center positions of the four driving motors 4 are set as A, B, C, and D respectively. The four driving motors 4 are located at the four vertices of a square with a side length of 180 mm on the load-bearing structure 1. The geometric center of this square is set as the coordinate origin O. Then the coordinates of the four points can be obtained as A(90, 90), B(-90, 90), C(-90, -90), D(90, -90). The radii of the circles A, B, C, and D are the same, which is the eccentric radius 5 mm of the eccentric coupling. Then the equations of the four circles can be obtained as follows:

[0021] Circle A: (x - 90) 2 +(y - 90) 2 = 25;

[0022] Circle B: (x + 90) 2 +(y - 90) 2 = 25;

[0023] Circle C: (x + 90) 2 +(y + 90) 2 = 25;

[0024] Circle D: (x - 90) 2 +(y + 90) 2 = 25;

[0025] The sieve 2 (sieve mesh) is connected to the four circles through the eccentric shaft of the eccentric coupling, and the eccentric coupling is driven by the four driving motors 4. The driving motors 4 are installed on the load-bearing structure 1 through the reserved holes. Under the synchronous action of the four driving motors 4, the sieve 2 also makes a circular motion. Then the motion mode of any point on the plane of the sieve 2 is the same as that of the sieve 2. Suppose there is any point E(a, b) on the plane of the sieve 2. Then the motion trajectory of point E can be calculated through a mathematical model to be a circle, and its equation is: (x - a) 2 +(y - b) 2 = 25, thus realizing uniform and continuous spreading of the retort material.

[0026] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
