Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection equipment technology, and in particular to a rapid particle size detection device. Background Technology
[0002] In the production and manufacturing of fuels, food, medicinal materials, building materials, etc., raw materials need to be made into pellets to meet usage requirements. The main methods of pelletizing include granulation and crushing. In the granulation process, the raw materials are usually small particles or powder with uniform particle size. By controlling the parameters, the particle size can be controlled. In the crushing process, there are often problems such as irregular shape of raw material blocks and poor internal uniformity of raw material blocks. It is necessary to test the particles obtained from crushing and then adjust the parameters of the crusher in real time.
[0003] To quickly detect particle size, those skilled in the art sample the crushed material, then screen and classify it, and weigh the screened and classified material separately to obtain the weight of each particle size grade after crushing, thereby judging the crushing effect. After weighing, the material is returned to the crushing system through a conveying device. However, since the sampling device, screening device, weighing device, and return device work separately, the particle size detection efficiency is low. Utility Model Content

[0008] The weighing device includes a weighing hopper connected to each discharge port of the multi-stage vibrating screen.
[0009] The return device includes a return conveyor belt disposed between the discharge ports of each weighing hopper, the discharge end of which is connected to the discharge conveyor belt of the crusher.
[0010] Furthermore, the multi-stage vibrating screen is connected to a dust removal pipe.
[0011] Furthermore, the discharge port of the multi-stage vibrating screen is connected to a discharge chute, the end of the discharge chute is connected to a discharge pipe, and the upper end of the weighing hopper is provided with a receiving port that cooperates with the discharge pipe, with a clearance fit between the discharge pipe and the receiving port.

The sampling device takes material from the discharge hopper of the crusher, and then the screening device screens and grades the material. The weighing device weighs the material of different particle size grades separately. After weighing, the material is returned to the crushing system through the return device, thereby enabling rapid particle size detection. Attached Figure Description
