Novel chemical material screening machine for chemical engineering

Abstract

The invention belongs to the technical field of screening machines, and discloses a novel chemical material screening machine for chemical engineering. The novel chemical material screening machine comprises a magnetic separation cylinder and a screening cylinder which are sequentially connected from top to bottom, wherein the magnetic separation cylinder and the screening cylinder can independently rotate; the magnetic separation cylinder is obliquely arranged, the two ends of the magnetic separation cylinder are rotationally matched with an upper end cover and a lower end cover correspondingly, a feeding hopper is arranged at the top part of the upper end cover, a material guiding bent pipe is arranged at the bottom part of the lower end cover, and the magnetic separation cylinder communicates with the screening cylinder through the material guiding bent pipe; a magnetic separation device is fixed between the upper end cover and the lower end cover, the magnetic separation device comprises a semi-annular guide plate with an upward opening, fixing bases are welded to the two ends of the semi-annular guide plate, the two fixing bases penetrate through the upper end cover and the lower end cover correspondingly, and a magnetic separation plate is rotatably connected between the two fixing bases; and the magnetic separation device has a self-cleaning function, so that metal chipsattached to the magnetic separation plate can be automatically removed regularly, on one hand, the magnetic separation effect is guaranteed, and on the other hand, material waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of screening machines, in particular to a novel chemical material screening machine for chemical industry. Background technique [0002] At present, in chemical production, materials of different sizes often need to be screened. The traditional method is mainly to use gauze for manual screening and filtration, which is labor-intensive for workers and relatively low in efficiency. Based on this, a chemical material screening machine for chemical industry is disclosed in the patent CN109926206B; specifically, the screening machine realizes magnetic separation and dispersion before material screening through the setting of a metal filings filter mechanism and a material dispersion mechanism; however, in practical applications There are still certain problems; for example: [0003] (1) According to the structure and principle disclosed in this patent, it can be seen that the metal chip filter mechanism complete...

AI Technical Summary

Problems solved by technology

[0003] (1) According to the structure and principle disclosed in this patent, it can be seen that the metal chip filter mechanism completes the adsorption of metal chips through the magnetic plate, and the adsorbed metal chips are attached to the surface of the magnetic plate. With the increase of the metal chips attached to the magnetic plate, the The friction force on the surface of the magnetic plate increases, and it even becomes uneven. At this time, the magnetic plate not only intercepts metal chips, but also intercepts some materials, which causes waste of materials to a certain extent; in addition, the surface of the magnetic plate is attached. Metal shavings are also difficult to clean, which affects the working efficiency of the screening machine;

[0004] (2) According to the structure and principle disclosed in the patent, the metal shavings filtering mechanism and the material dispersing mechanism are set independently, which makes the overall screening machine larger in size and more complex in structure, and thus has the problems of high cost and difficult maintenance
