Problems solved by technology

This method can have an intuitive feeling for the mixing of pellet raw materials, but this method cannot be used for quantitative analysis, it is only for image judgment, and this method has serious hysteresis, so this method cannot achieve online mixing uniformity of pellet raw materials detection
Another method is to vaguely judge the degree of mixing of the pellet raw materials by the amount of bentonite used, the pelletizing performance of the mixed material, and the progress of the subsequent process. This method cannot accurately and instantly measure the mixing uniformity of the pellet raw materials. Judgment, unable to guide production in time

Embodiment 1

[0071] like figure 1 , a pellet raw material mixing degree detection device, including a sampling system 3, station switching and unloading system 1, microwave rapid drying system 2. The sampling system 3 is installed at the front end of the upper part (top cover) of the station conversion and unloading system 1, and the microwave rapid drying system 2 is installed at the rear end of the upper part (top cover) of the station conversion and unloading system 1. The sampling system 3 Input the material samples to be tested into the station conversion and unloading system 1 through the feeding funnel 100, and the microwave rapid drying system 2 communicates with the station conversion and unloading system 1 through the microwave cut-off pipe 204 as the sample lifting channel. Wherein the station conversion and unloading system 1 has at least three stations: feeding position A, microwave drying position B and unloading position C, and the rotary mechanism 103 of the station convers...

Embodiment 2

[0076] Repeat Example 1, except that the axis of the rotating mechanism is the apex of the angle, and the included angles between the three stations are 90°, 120° and 150° respectively.

Embodiment 3

[0078] A method for detecting the mixing degree of pellet raw materials, comprising the steps of:

[0079] 1) After the sampling spoon 302 picks up the material from the belt feeding place of the belt conveyor, it is driven by the linear motor 301 to recycle, and the scraper brush 303 scrapes off the material in the sampling spoon 302, and the sample material flows into the feeder along with the feeding funnel 100 Inside the sample box 102 made of quartz glass supported by the rotating mechanism 103 at position A; the first lifting device 106 drives the first weighing device 104 to rise vertically to support or hold the sample box 102 for the first weighing After the first weighing is completed, the first lifting device 106 drives the first weighing device 104 to descend vertically, and the weighed sample box 102 is supported by the rotating mechanism 103 again;

[0080] 2) The rotary mechanism 103 transfers the weighed sample box 102 from the feeding position A to or rotates ...

Abstract

The invention discloses a mixing-uniformity detecting device for water-containing materials. The mixing-uniformity detecting device comprises a working-position shifting and discharging system and a microwave fast-drying system, wherein the microwave fast-drying system is arranged above the working-position shifting and discharging system and consists of a microwave generator box body and a microwave drying box which are partitioned by a partitioning plate; microwave transmission holes are arranged on the partitioning plate, and the microwave fast-drying system is communicated with the working-position shifting and discharging system at the lower part by a microwave stopping pipe as a sample lifting channel, wherein the working-position shifting and discharging system is provided with three working positions, namely a feeding position, a microwave drying position and a discharging position, a rotating mechanism of the working-position shifting and discharging system rotates or revolves in operation, so that a sample container rotates from one working position to another working position; and a feeding hopper is arranged at the top part of the working-position shifting and discharging system and is positioned above the feeding position; the inclined angle of the three working positions is 120 degrees.

Description

technical field [0001] The invention relates to a device for detecting the mixing uniformity of water-containing materials built in a microwave generator and a detection method thereof, more specifically, in the production process of pellets in iron and steel smelting, it relates to a device for detecting the uniformity of mixing of pellet raw materials and its detection method. Background technique [0002] For the detection of mixing uniformity of water-containing materials in the prior art, especially the online detection of the production line, on the one hand, it is often impossible to quickly obtain the detection results and adjust the mixing process conditions in time through the feedback of the detection results. On the other hand, due to sampling The process of sending and testing takes a lot of time, and the evaporation of water in this process will also lead to inaccurate detection accuracy. [0003] When the inventor visited the pellet production process of the ...
