Nozzle structure for color sorter

Abstract

The invention relates to the technical field of color sorters, in particular to a nozzle structure for a color sorter. The nozzle structure comprises a base block capable of rotating by 360 degrees and a plurality of mutually independent nozzles mounted on the base block, the base block is mounted between a first side plate and a second side plate in the color sorter, and the base block can rotate by 360 degrees and can suspend at any angle; and the nozzles and sealing plates are detachably and movably connected with the base block through studs. According to the nozzle structure, the multiple independent nozzles are arranged on the end face of the rotatable base block, and when different materials are sorted, the falling angles of the nozzles relative to the materials can be adjusted by adjusting the angle of the base block, so that the color sorter obtains a better sorting effect; and when the materials are large or small, redundant nozzles can be replaced by using the sealing plates, so that sufficient air pressure of the nozzles is always ensured, and the stability of nozzle sorting is improved.

Description

technical field [0001] The invention relates to the technical field of color sorters, in particular to a nozzle structure for a color sorter. Background technique [0002] The color sorter is a non-destructive sorting equipment used for quality detection and classification of bulk materials. According to the difference in optical characteristics of materials, it uses photoelectric detection technology to automatically sort out the heterochromatic particles in granular materials. It is used in grain, Food, pigment chemical industry and other industries have a wide range of applications. The domestic high-resolution CCD + infrared composite color sorting machine can sort plastic, glass, metal, the same color rod and other malignant impurities in the grain. The color sorter generally includes a frame , Feeding mechanism and color sorting device, the feeding mechanism transports the materials to be selected to the identification slideway at a uniform speed, the color sorting dev...

AI Technical Summary

Problems solved by technology

[0003] Most of the sorting devices used in the existing color sorters realize the sorting function by installing multiple nozzles side by side at the lower end of the slideway inside the color sorter. This structure has two shortcomings. First, the number of existing nozzles Fixed, when faced with the need to sort materials of different sizes, there may be a problem of insufficient number of nozzles, and the existing nozzles are integrated in a box, when a nozzle fails or is blocked, it needs to be replaced The entire box is taken out from the color sorter and then disassembled for maintenance, which is cumbersome and cannot be installed with nozzles. Second, once the existing nozzles are installed inside the color sorter, it is impossible to adjust the position of the nozzles. Orientation angle, when the material is small or large, it will increase the misalignment probability of material falling or cause the nozzle to not spray gas to the material at an optimal angle, reducing the multi-functionality of the color sorter
