Embodiment 1

[0028] This embodiment illustrates: the mixing effect of the mixer provided by the present invention.

[0029] Cracking catalyst MLC-2300, MLC-500 (trade name, both industrially produced by Qilu Petrochemical Company Catalyst Factory) two kinds of powder, of which the bulk ratio of MLC-2300 is 670Kg / M 3 , the median particle size is 76 microns; the bulk ratio of MLC-500 is 700Kg / M 3 , with a median particle size of 68 microns. Get above-mentioned two kinds of catalyzers by the ratio of 1: 1 and use the continuous mixer of the present invention to mix now, through 20 times of sampling analysis, the density after recording mixing is 687Kg / M 3 , the median particle size is 71 microns; the average heap ratio of the theoretical mixture is 685Kg / M 3 , the median particle size is very close to 71 microns, and the standard deviation of the density of each sample is 1.2%. After 20 times of sampling, the chemical composition of the powder after mixing is analyzed, and the standard dev...

Embodiment 2

[0033] This embodiment illustrates: the mixing effect of the mixer provided by the present invention.

[0034] Adopt two kinds of powders identical with comparative example 1, mix on the device of the present invention, according to the same ratio, through mixing once, the time used is 2-3 minutes, the average density after recording mixing is 708Kg / M 3 , and the average heap ratio of the theoretical mixture is 706.7Kg / M 3 Very close, the median particle size is 68.3 microns, which is also close to the ideal mixing median particle size of 67.7 microns; multi-point sampling of the output, chemical composition analysis, the standard deviation of each powder after mixing is 1.4%, This shows that the mixing time used in the present invention is short and the mixing uniformity is good.

Embodiment 3

[0039] Adopt four kinds of powders identical with comparative example 2, mix on the device of the present invention, in the same proportion, through one mixing, the time used is 2-3 minutes, the average density after the mixing is recorded as 661Kg / M 3 , with a median particle size of 67.4 microns. Multi-point sampling is carried out on the discharge, and chemical composition analysis is carried out. The standard deviation of each powder after mixing is 1.8%. It can be seen that the mixing time used in the present invention is short and does not need multiple cycles.

Premixing chamber, sprinkling pan and collector are placed in gravity direction. Premixing palm and sprinkling pan are installed in same axis. The blending machine has a simple and novel construction and flexible operation. It can realize fine material blending continually and automatically.

Description

technical field [0001] The invention relates to solid powder mixing equipment, more specifically, a continuous solid powder mixer. Background technique [0002] In the industrial production of chemical industry, metallurgy, food, building materials, pharmaceuticals, etc., powder preparation and treatment are inseparable, and mixing is an important link in powder preparation and treatment. Due to the requirements of the production process, it is often necessary to mix more than two kinds of powder raw materials, and it is hoped to obtain a solid powder mixture in which various powder components are uniformly mixed. Also in the production of powder as the final product, with the fluctuation of production conditions, sometimes the product quality will fluctuate to a certain extent; in order to ensure the stability of product quality, it is sometimes necessary to mix products produced in different batches. In continuous industrialized mass production, how to achieve continuous ...
