Description

Technical Field

[0001] The utility model relates to the field of acceleration discs, in particular to a centrifugal acceleration disc. Background Art

[0002] The circular flat plate acceleration plate commonly used in the double-stage piston push centrifuge is composed of a pointed cone guide structure in the middle and a circular flat plate. Under the action of centrifugal force, the material gradually moves outward along the flat plate and is screened by the outer screen.

[0003] In current technology, multiple spherical materials are prone to slip on the disc, causing the centrifugally accelerated materials on the disc to directly collide with each other. Due to unreasonable acceleration, the linear speed difference of multiple materials leaving the acceleration disc is large, resulting in unstable material ejection speed. Some materials hit the screen at high speed, causing the materials to be scratched, ground, damaged or broken, affecting product quality. Utility Model Content

[0004] The purpose of the utility model is to solve any one of the problems in the above-mentioned technologies, thereby proposing a centrifugal acceleration disc.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a centrifugal acceleration disk, a disc-shaped disk body and a circular material dividing head with an arc surface on the top arranged in the center, a plurality of turbine blade walls distributed in a circumferential array are arranged on the periphery of the upper surface of the disk body, and the plurality of turbine blade walls divide the surface of the disk body into a plurality of areas to centrifugally accelerate the material, thereby reducing the space for the material to slip and thus reducing the linear velocity difference of the material leaving the acceleration disk.

[0006] Furthermore, the inner radius R1 of the material distribution head is 54mm, the outer radius R2 of the centrifugal acceleration disk is 132mm, the adapted acceleration material specification is a round spherical material with a radius of 15-23mm, and the inner opening size of the turbine blade wall is 50mm.

[0007] Furthermore, the inlet placement angle β1 of the turbine blade wall is 53°, the outlet placement angle β2 of the turbine blade wall is 35°, and the wrap angle of the turbine blade wall is The polar angle of the turbine blade wall is 35°. The angle β of the turbine blade wall is 22° and the angle β of the turbine blade wall is 41°.

[0008] Furthermore, the turbine blade wall is made of SLA-soft resin material, and the disc body and distributor head are made of SLS-glass fiber nylon material.

[0009] The beneficial effects of the present utility model are as follows: Multiple turbine blade walls divide the surface of the disk body into multiple regions to centrifugally accelerate the material. The material sequentially enters the turbine blade walls and is accelerated by them, reducing the space for the material to slip and decreasing the frequency of direct collisions between the materials. As a result, the linear velocity difference of the material leaving the acceleration disk is reduced, enabling the velocity of the material thrown onto the sieve to be stabilized within a limited range, accelerating the discharging, and improving the output and quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 is a dimension identification diagram of the turbine blade wall of the present utility model.

[0012] In Figures 1 to 2 , the corresponding relationship between the component names or lines and the drawing reference numerals is: disk body 1, turbine blade wall 2, and material distributor 3. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] Please refer to Figures 1 to 2 ;

[0014] This embodiment provides a centrifugal acceleration disk, including a disk-shaped disk body 1 and a circular material distributor 3 with an arc-shaped top disposed at its center. A plurality of turbine blade walls 2 are arranged in a circumferential array on the outer periphery of the upper surface of the disk body 1. The plurality of turbine blade walls 2 divide the surface of the disk body 1 into multiple regions to centrifugally accelerate the material, reducing the space for the material to slip and thus reducing the linear velocity difference of the material leaving the acceleration disk.

[0015] Preferably, the inner radius R1 of the material distributor 3 is 54 mm, the outer radius R2 of the disk body 1 of the centrifugal acceleration disk is 132 mm, the suitable acceleration material specification is circular spherical material with a radius of 15 - 23 mm, and the inner opening size of the turbine blade wall 2 is 50 mm.

[0016] In a specific embodiment, the inner opening size of the turbine blade wall 2 is 50 mm, and the acceleration material specification is circular spherical material with a radius of 15 - 23 mm. Due to the limitation of the opening size, the spherical material can only enter the turbine blade wall 2 one by one for acceleration, effectively avoiding the situation where too much material enters at one time and causes direct collisions between the materials.

[0017] Preferably, the inlet installation angle β1 of the turbine blade wall 2 is 53°, the outlet installation angle β2 of the turbine blade wall 2 is 35°, the wrap angle of the turbine blade wall 2 is 35°, the polar angle of the turbine blade wall 2 is 22°, and the installation angle β of the turbine blade wall 2 is 41°.

[0018] In a specific embodiment, the radian of the turbine blade wall 2 decreases successively from the inside to the outside. When the spherical material enters the turbine blade wall 2, it is pushed by the wall to accelerate centrifugally and gradually moves outward along the wall, and is thrown out from the end of the turbine blade wall 2.

[0019] Preferably, the turbine blade wall 2 is made of SLA-soft rubber resin, and the disk body 1 and the material distributor 3 are made of SLS-glass fiber nylon.

[0020] In a specific embodiment, the material properties of the SLA-soft rubber resin are as follows:

[0021]

[0022] The SLA-soft rubber resin has good elastic properties and can effectively reduce the probability of bruising the spherical material during acceleration by the turbine blade wall 2.

[0023] In a specific embodiment, the material properties of the SLS-glass fiber nylon are as follows:

[0024]

[0025] The surface of the glass fiber nylon material has obvious granularity, can withstand high temperature of 170 °C, has very good strength, high hardness, is not easy to bend, and the granules on the surface after material forming effectively reduce the probability of the spherical material slipping.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
