Description

Technical Field

[0001] The utility model relates to the field of powder and granular material mixing and distributing, in particular to a device for mixing and distributing light spar powder and granular material. Background Art

[0002] At present, when conveying single raw materials such as powders and granules, they are mainly divided by three-way distributors, which are electric, hydraulic, pneumatic and other types of three-way distributors. When the raw material is a single powder or granule, the raw material can fall evenly into the hopper below through the three-way distributor. However, for a mixture of powder and granules, when the material falls into the hopper below through the dividing slope of the three-way distributor, the powder and granules in the mixture are separated due to the different repose angles of the powder and granules.

[0003] There is a problem when distributing the light spar raw material system: the powder and granular materials in the raw materials are stratified after passing through the three-way distributor, which affects the subsequent distribution and firing process and directly leads to uneven surface texture and particles of the product's microcrystalline surface. Utility Model Content

[0004] In order to solve the problem of stratification of the mixture of light spar powder and granular material during the material distribution process of the three-way distributor, the utility model proposes a light spar powder and granular material mixed material distribution device, which can distribute the materials evenly and improve the product quality. The specific technical scheme is as follows:

[0005] A light spar powder and granular material mixing and distributing device comprises a shell, a lower hopper is provided on the upper side of the shell, a pair of rotors with opposite rotation directions are arranged in the shell, the rotor comprises a rotating shaft arranged in the front-back direction and blades installed on the rotating shaft; both ends of the rotating shaft are installed on the shell through seat bearings, the two rotors are arranged symmetrically, a pair of motor reducers corresponding to the positions of the rotating shafts are provided outside the shell, and the motor reducers are coaxially connected to the corresponding rotating shafts respectively.

[0006] Furthermore, the lower hopper is connected to the shell through a connecting flange.

[0007] Furthermore, the motor reducer is frequency-controlled by a frequency converter.

[0008] Furthermore, a reducer mounting seat is provided outside the shell, the motor reducer is arranged on the reducer mounting seat, and the motor reducer is fixed outside the shell by screws.

[0009] Furthermore, the blades are arc-shaped or parabolic-shaped.

[0010] Furthermore, the blades are evenly distributed along the circumferential direction of the shaft, and the number of blades is 4-8.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model solves the problem of stratification of the mixture of light crystal stone powder and granular material during the distribution process of the three-way distributor. The mixture of powder and granular material falls evenly to the bottom of the shell after being distributed by the rotor. The surface texture and particles of the light microcrystalline stone raw material mixture after distribution are uniform after sintering.

[0013] 2. The motor reducer is frequency-controlled to match the rotor speed with the material discharge speed of the hopper, ensuring uniform material distribution. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Preferably, the motor reducer 4 is frequency-controlled by a frequency converter, so that the rotation speed of the rotor 2 matches the material discharge speed of the discharge hopper 1, and the material is evenly distributed.

[0024] Preferably, a reducer mounting seat 6 is provided outside the housing 3 , the motor reducer 4 is arranged on the reducer mounting seat 6 , and the motor reducer 4 is fixed to the outside of the housing 3 by screws.

[0025] Preferably, the blades 22 are arc-shaped or parabolic-shaped, and the blades 22 are evenly distributed along the circumference of the rotating shaft 21 , and the number of the blades 22 is 4-8.

[0026] During operation, the mixture of light spar powder and granular material enters the shell 3 through the lower hopper 1, and the material falls to the bottom of the shell 3 through the rotor 2. There is no accumulation, and stratification is avoided. The mixed material falls evenly to the bottom of the shell 3, which is beneficial to the subsequent material distribution and sintering process.

[0027] The problem of stratification of the mixture of light spar powder and granular material during the distribution process of the three-way distributor is solved. The mixture of powder and granular material falls evenly to the bottom of the shell 3 after being distributed by the rotor 2. The surface texture and particles of the light microcrystalline stone raw material mixture after distribution are uniform after sintering. The motor reducer 4 is frequency-controlled to match the rotation speed of the rotor 2 with the discharge speed of the discharge hopper 1, and the distribution is uniform.
