Problems solved by technology

[0003] During the production and processing of chemical products, the raw materials and intermediate materials are easily mixed with some impurities during processing, storage or transportation, which will affect the subsequent processing and product quality. Therefore, it is necessary to screen the raw materials or intermediate materials processing to quickly remove impurities in the material; most of the material is granular, and screens are mostly used for screening, some of which are swingable and rotatable screens, in order to ensure that the materials will not be accidentally discharged from the screen during the screening process. The side of the screen is equipped with retaining structures, or the screen is directly set as a groove structure, so after screening and removing impurities, the accumulated impurities on the screen are not easy to discharge

Embodiment 1

[0033] Please refer to the accompanying drawings, the present invention provides a technical solution: a chemical material screening device that facilitates rapid separation and removal of impurities, including a screening box 1 and a feed hopper 2, and a feed pipe 201 is fixed in the middle of the bottom of the feed hopper 2 , the bottom of the feed hopper 2 is inclined towards the feed pipe 201, and the bottom end of the feed pipe 201 extends into the upper part of the inner cavity of the screening box 1, and the bottom surface of the inner cavity of the screening box 1 is set as a circular arc surface, and the front and rear sides The center position of the wall corresponding to the arc surface of the screening box 1 is rotatably connected with a rotating shaft 4, and a screening assembly is fixed between the inner ends of the two rotating shafts 4, and the upper part of the left section of the arc-shaped bottom of the screening box 1 is provided with an inclined first The l...

Embodiment 2

[0045] The structure of this embodiment is basically the same as that of Embodiment 1, except that an arc-shaped third sealing plate 305 is arranged above the screening assembly, and the center of circle of the third sealing plate 305 coincides with the center of the rotating shaft 4, and the right side The end extends downward along the arc direction, and is fixedly connected with the top right section of the rotating plate 3, a support rod 306 is fixed between the left end and the top left side of the rotating plate 3, and the bottom end of the feed pipe 201 is provided with arc-shaped, and the bottom end is slidingly connected with the top surface of the third sealing plate 305 .

[0046] The right side of the inner cavity of the feed pipe 201 is fixed with a material guide block 202, the top surface of the material guide block 202 is inclined, the left side is low and the right side is high, and the left side is located on the left side of the center of the rotating shaft 4...

Embodiment 3

[0049] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that an arc-shaped block 403 is fixed on the inside of the left section of the rotating rod 401, and the center of the arc-shaped block 403 coincides with the center of the rotating shaft 4. The wall is correspondingly provided with an arc groove 104, and the arc block 403 is slidably connected in the arc groove 104, and springs are respectively connected between the two ends of the arc block 403 and the inner two ends of the arc groove 104, when swinging When the component drives the screening component to rotate through the rotating shaft 4, the first screen 301 and the second screen 302 will tilt, and the material will move to the lower end, so that the screening component and the swinging component will be affected by the gravity of the material, and the impact of the gravity of the material will be slowed down by the spring. Effects of individual components of the scree...

Abstract

The invention discloses a chemical material screening device facilitating rapid separation and impurity removal in the technical field of chemical material screening. The chemical material screening device comprises a screening box and a feeding hopper, the interior of the screening box is connected with a screening assembly through rotating shafts, and the outer side end of one rotating shaft extends out of the screening box and is connected with a rotating mechanism; the rotating mechanism comprises a swinging assembly and a moving assembly, the swinging assembly drives a first screen and a second screen to swing back and forth in a small range to screen materials, and impurity removal and graded screening are achieved at the same time under the action of the first screen and the second screen; the swinging assembly is adjusted to the left side section of a connecting groove through the moving assembly, the rotation amplitude of a follow-up rotating rod is increased, and then the left side ends of the first screen and the second screen can rotate to groove openings of a first discharging groove and a second discharging groove correspondingly, and therefore, impurities and materials accumulated on the first screen and the second screen can be discharged and collected respectively.

Description

technical field [0001] The invention relates to the technical field of chemical material screening, in particular to a chemical material screening device for rapid separation and impurity removal. Background technique [0002] Chemical industry includes petrochemical industry, agricultural chemical industry, chemical medicine, polymer, coating grease, etc. They appear in different historical periods and have different meanings, but they are closely related, interpenetrating, continuous, and endowed with new content in the course of their development. Early human life relied more on direct utilization of natural substances. Gradually, the inherent properties of these substances cannot meet the needs of human beings, so various processing technologies have been produced to consciously and purposefully transform natural substances into new substances with various properties, and gradually realize them on the scale of industrial production. Broadly speaking, anyone who uses ch...
