Detailed Description

As shown in fig. 1 to 6, the resin screening apparatus according to the present embodiment includes a charging device 5, a screen plate assembly for receiving material falling from the charging device 5, a conveyor 1 for obliquely distributing and for driving the screen plate assembly in a circular motion, a collecting device a3 for receiving waste falling from the screen plate assembly at the top end of the upper surface of the conveyor 1, and a collecting device b4 for receiving qualified material sliding from the screen plate assembly at the bottom end of the upper surface of the conveyor 1, wherein the collecting device a3 and the collecting device b4 may be designed in a box shape or a barrel shape.

The sieve plate component moves above the conveying device 1 along the upward direction of inclination, the sieve plate component moves below the conveying device 1 along the downward direction of inclination, namely, when materials fall onto the sieve plate component through the feeding device 5, the sieve plate component moves upward in an inclined mode, the spherical particle adsorbent materials can directly roll off, and other special-shaped, incomplete or broken particles and mixed impurities can be driven to the top end of the conveying device 1 by the sieve plate component under the action of friction force between the special-shaped, incomplete or broken particles and the mixed impurities and the sieve plate component, and then fall freely, so that the screening of the materials is realized.

As shown in fig. 6, the screen plate assembly includes a plurality of screen plates 2 equally spaced on the conveyor 1 so as to be smoothly conveyed by the conveyor 1. One end of the sieve plate 2 is in buckling connection or rotating connection with the conveying device 1. The multiple screening plates 2 are sequentially and tightly attached when moving to the upper part of the conveying device 1, can receive materials to be screened falling from the feeding device 5, and freely hang down when moving to the lower part of the conveying device 1. The screen plate 2 can be vertically distributed with the conveying device 1 when moving below the conveying device 1, and at this time, a positioning structure, such as a positioning block, needs to be arranged on the conveying device 1, and when the screen plate 2 rotates to the position of the positioning block, the screen plate is blocked by the positioning block, cannot continue to rotate, and can only be maintained at an angle vertical to the conveying device 1, so that screening is ensured to be clean and free of residues.

The protection devices for preventing materials from sliding off from the sides are arranged at the two ends of the width direction of the screen plate 2, so that the materials can only move along the length direction of the screen plate 2 and can only fall into the collecting device a3 or the collecting device b4, and effective screening of the materials is realized. In the screening process, the speed of the reverse running of the screen plate 2 can be properly adjusted according to the factors such as the particle size, the specific gravity and the screening effect of the spherical particle adsorbent, so that the screening result can meet the requirements, and the qualified and unqualified spherical particle adsorbent can be respectively collected after the screening is finished.

The sieve plate 2 is made of stainless steel materials, so that the electrostatic effect of the spherical particle adsorbent and pollution to the spherical particle adsorbent can be effectively avoided, and the spherical particle adsorbent can be effectively cleaned and disinfected.

The conveying device 1 comprises a servo motor and a conveying belt (the servo motor drives a rotating roller to rotate, the rotating roller drives the conveying belt to rotate) or a chain (the servo motor drives a chain wheel to rotate, and the chain wheel drives the chain to rotate), and the screen plate 2 is mounted on the conveying belt or the chain and driven by the conveying belt and the chain to rotate.

As shown in fig. 1, the feeding device 5 is in a flat funnel shape, so that the material can uniformly fall onto the lower sieve plate 2 for sieving after passing through the feeding device 5, and the feeding device 5 is preferably arranged above the middle position of the conveying device 1.

The method can effectively screen out abnormal, incomplete or broken particles and other mixed sundries, and can continuously run and simplify operation, so that time and labor are saved. The conveying device 1 drives the sieve plate 2 to run anticlockwise, the material to be screened falls onto the sieve plate 2 above the conveying device 1 through the feeding device 5, the friction force between the spherical particle adsorbent material and the sieve plate 2 is insufficient for blocking the material from rolling off, and the spherical particle adsorbent material can slide into the collecting device b4 from the sieve plate 2; for special-shaped, incomplete or broken particles and mixed impurities, the special-shaped, incomplete or broken particles and mixed impurities can be obliquely and upwardly conveyed by the sieve plate 2 due to the friction force between the special-shaped, incomplete or broken particles and mixed impurities and the sieve plate 2, and when the special-shaped, incomplete or broken particles and mixed impurities are conveyed to the top end, the special-shaped, incomplete or broken particles and mixed impurities can directly fall into the collecting device a3 from the sieve plate 2. The feeding device 5 can continuously add the material to be screened on the screen plate 2, and the screen plate 2 can continuously run, so that the aim of high-efficiency automatic screening of the material is fulfilled, the screening quality is high, dust pollution can not be generated during screening, and secondary damage to adsorbent particles can not be caused.
