Description

Technical Field

[0001] This utility model relates to the field of sodium carboxymethyl cellulose screening technology, specifically to an intelligent screening device for fast-dissolving sodium carboxymethyl cellulose. Background Technology

[0002] Instant-soluble sodium carboxymethyl cellulose is a sodium carboxymethyl cellulose derivative processed by a special process. Compared with ordinary sodium carboxymethyl cellulose, its biggest feature is its fast dissolution speed and good dispersibility. It can form a uniform colloidal solution in a short time. The physical state of instant-soluble sodium carboxymethyl cellulose is mainly powder or granules.

[0003] The intelligent screening device for fast-dissolving sodium carboxymethyl cellulose is an automated screening equipment designed for its powder or granular characteristics. It achieves efficient grading, impurity removal and quality control through intelligent technology, ensuring that the product has uniform particle size and meets the purity standards. It is suitable for subsequent rapid dissolution and application needs. The core requirement of fast-dissolving screening is to control the particle size distribution to avoid agglomeration or large particles affecting the dissolution rate and impurity removal.

[0004] Existing screening devices typically grind sodium carboxymethyl cellulose (CMC) before screening it using a vibrating screen. However, the vibrating screen causes the CMC particles to bounce and impact at high frequencies, resulting in clumping or breakage of intact particles. This affects the screening efficiency and particle uniformity of the CMC, ultimately reducing the efficiency and effectiveness of the screening device. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent screening device for fast-dissolving sodium carboxymethyl cellulose.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A smart screening device for fast-dissolving sodium carboxymethyl cellulose is provided, comprising a screening box, support legs, a box cover, a screening mechanism, and a vibration mechanism. The support legs are fixedly installed at the bottom of the screening box, the box cover is fixedly installed on the screening box, the screening mechanism is used to screen the material in the screening box, and the vibration mechanism is used to drive the screening mechanism to vibrate.

[0008] The screening mechanism includes a screening plate and a moving mechanism. The screening plate is slidably installed inside the screening box via support blocks, and the moving mechanism drives the screening plate to reciprocate. Through the reciprocating movement of the screening plate, a uniform and qualitative pushing force is generated on the material on the screening plate, allowing the material to slide and spread evenly on the screening plate, reducing friction and impact between particles and between particles and the screening plate.

[0009] Furthermore, the screening mechanism also includes a rotating shaft, a grinding roller, and a filter plate. The filter plate is slidably installed inside the screening box, the rotating shaft is rotatably installed on the box cover, and the rotating shaft passes through the filter plate. The grinding roller is fixedly installed on the rotating shaft by a mounting ring. The rotation of the rotating shaft drives the grinding roller to rotate, grinding the material on the filter plate.

[0010] Furthermore, the screening mechanism also includes a motor and a conveying mechanism. The motor is fixedly installed on the cover, and the output shaft of the motor is fixedly connected to the rotating shaft. The conveying mechanism is used to convey the material after screening by the screening plate.

[0011] Furthermore, the moving mechanism includes a U-shaped rod, a ring, and a connecting block. The U-shaped rod is slidably mounted on the screening plate via a cylindrical tube, the ring is rotatably mounted on the connecting block via the cylindrical block, and the ring passes through the U-shaped rod. The connecting block is fixedly mounted on the rotating shaft. The rotation of the rotating shaft simultaneously drives the screening plate to reciprocate.

[0012] Furthermore, the conveying mechanism includes a housing and a guide plate. The screening box has a discharge port, the guide plate is fixedly installed on the screening box, the housing is fixedly installed on the screening box, and the housing is connected to the guide plate.

[0013] Furthermore, the conveying mechanism also includes an electric scraper conveyor belt, which is fixedly installed inside the housing, which is connected to the screening box via a connecting pipe. The scraper conveyor belt can return unqualified materials after screening to the filter plate for secondary grinding.

[0014] Furthermore, the vibration mechanism includes a support ring and a guide rod. The support ring is fixedly installed inside the screening box, and the filter plate is connected to the support ring by a spring. The guide rod is fixedly installed at the bottom of the filter plate and passes through the support ring.

[0015] Furthermore, the vibration mechanism also includes a T-shaped plate and a T-shaped rod. The T-shaped plate is fixedly installed at the bottom of the guide rod. A sliding groove is provided on the screening box, and the T-shaped plate is slidably connected to the sliding groove. A through groove is also provided on the T-shaped plate, and the T-shaped rod is fixedly installed on the screening plate, passing through the through groove. Through the rotation of the rotating shaft, the filter plate can be driven to move reciprocally vertically, thereby causing the filter plate to vibrate, improving the filtration efficiency of the filter plate and preventing clogging.

[0016] The beneficial effects of this utility model are as follows: This intelligent screening device for fast-dissolving sodium carboxymethyl cellulose, through its screening and moving mechanisms, enables the screening plate to move back and forth, allowing the sodium carboxymethyl cellulose particles to slide and spread evenly, reducing the impact and friction between particles, thus improving the screening device's performance and efficiency. In addition, the vibration mechanism enables the filter plate to vibrate, reducing the squeezing effect of the grinding rollers on the sodium carboxymethyl cellulose particles and preventing filter screen blockage, thereby further improving the filter screen's filtration efficiency and effect.

The screening mechanism 4 also includes a rotating shaft 42, a grinding roller 44, and a filter plate 45. The filter plate 45 is slidably installed inside the screening box 1. The filter plate 45 is used to filter the material, so that the ground material can fall from the filter holes of the filter plate 45 onto the screening plate 47. The rotating shaft 42 is rotatably installed on the box cover 3 and passes through the filter plate 45. The rotation of the rotating shaft 42 can drive the mounting ring 43 to rotate, thereby driving the grinding roller 44 to rotate.
