Description

Technical Field

[0001] This utility model relates to the field of silica gel particle production technology, and in particular to a silica gel screening structure that can flexibly adjust the feed amount according to the particle size. Background Technology

[0002] Silica gel particles have a highly developed microporous structure and a huge specific surface area, which enables them to strongly adsorb various substances. They are a highly active adsorbent material. They are usually made by reacting sodium silicate with sulfuric acid and then undergoing a series of post-processing processes such as aging, acid soaking, washing, and drying. After production, silica gel particles need to be screened and graded according to their particle size.

[0003] The feed inlet size of existing silica gel screening structures is fixed and cannot be adjusted according to the silica gel particle size. Silica gel with smaller particle size has poor flowability and is prone to clogging when passing through the screen holes. Silica gel with larger particle size has good flowability, but when passing through a fixed-size feed inlet, the discharge volume per unit time is relatively small, affecting screening efficiency. Therefore, a silica gel screening structure that allows for flexible adjustment of the feed volume according to particle size is provided. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a silica gel sieve structure that allows for flexible adjustment of the feed amount according to particle size.

[0005] Therefore, this utility model provides a silica gel screening structure that can flexibly adjust the feed amount according to the particle size, including an outer box. A connecting frame is fixedly connected to the upper left side of the inner side of the outer box. A feeding device is movably connected to the outer side of the connecting frame. A collecting device is fixedly connected to both sides of the outer box. A placement frame is fixedly connected to the inner side of the outer box. A screen plate is movably connected to the inner side of the placement frame. The feeding device includes a lifting plate movably connected to the outer side of the connecting frame. The lifting plate has screw holes and lifting holes inside. A rotating cylinder is fixedly connected to the right side of the lifting plate. A rotating column is movably connected to the inner side of the rotating cylinder. A rotating plate is fixedly connected to the outer side of the rotating column. A rotating rod is movably connected to the inner side of the rotating plate.

[0006] Preferably, the outer box includes a box body, a feed pipe is fixedly connected to the upper part of the box body, a first discharge port is provided on the left side of the box body, a second discharge port is provided on the right side of the box body, a guide plate is fixedly connected to the lower part of the box body, and sliding grooves are provided on both the front and rear sides of the inner side of the box body.

[0007] Preferably, the collection device includes a placement shell fixedly connected to both sides of the outer box, and a collection box is placed inside the placement shell. The collection box has handles fixedly connected to both the front and rear sides.

[0008] Preferably, the connecting frame includes a fixed plate fixedly connected to the upper left side of the inner side of the outer casing, a guide rod fixedly connected between the fixed plate and the outer casing, a stud movably connected between the fixed plate and the inner side of the outer casing, and a throttle fixedly connected to the upper side of the stud.

[0010] Preferably, the placement frame includes a frame body fixedly connected inside the outer box, and rubber strips are fixedly connected to both the left and right sides of the inner side of the frame body.

[0011] This invention provides a silica gel sieve structure that allows for flexible adjustment of the feed rate according to particle size, offering the following advantages:

[0012] This invention, by incorporating a feeding device and a connecting frame, facilitates the adjustment of the feeding speed according to the size of the silica gel particles. Twisting the handle allows the stud to rotate, and the forward or reverse rotation of the stud causes the lifting plate to rise and fall. This adjustment of the lifting plate allows for the adjustment of the distance between the right end of the rotating plate and the inner wall of the housing, and the tilt angle of the rotating plate can change synchronously. When screening smaller silica gel particles, the gap between the rotating plate and the housing is smaller, and the tilt angle of the rotating plate is also smaller, ensuring that smaller silica gel particles pass through the gap at a slower speed, preventing excessively fast feeding speeds that could clog the screen holes. When screening larger silica gel particles, the gap between the rotating plate and the inner wall of the housing is larger, and the tilt angle of the rotating plate is larger, ensuring that larger silica gel particles pass through the gap at a faster speed, increasing the discharge volume of larger silica gel particles per unit time, and thus improving the screening efficiency for larger silica gel particles.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Depend on Figures 1-5As shown, this utility model provides a silica gel sieving structure with adjustable feed rate according to particle size. It includes an outer casing 1, a connecting frame 3 fixedly connected to the upper left side of the inner side of the outer casing 1, a feeding device 4 movably connected to the outer side of the connecting frame 3, and collecting devices 2 fixedly connected to both sides of the outer casing 1. A placement frame 6 is fixedly connected inside the outer casing 1, and a sieve plate 5 is movably connected inside the placement frame 6. The feeding device 4 includes a lifting plate 401 movably connected to the outer side of the connecting frame 3. The lifting plate 401 can rise and fall outside the guide rod 302. The lifting plate 401 has a screw hole 402 and a lifting hole 404 inside. The screw hole 402 is adapted to the thread on the outer side of the stud 303. The right side of the lifting plate 401 is fixedly connected to the connecting frame 3. A rotating drum 403 is fixedly connected to the rotating cylinder 403, and a rotating column 405 is movably connected inside the rotating drum 403. The rotating drum 403 and the rotating column 405 can rotate relative to each other, so that the lifting plate 401 and the rotating plate 406 can rotate relative to each other. The rotating plate 406 is fixedly connected to the outside of the rotating column 405, and a rotating rod 407 is movably connected inside the rotating plate 406. The rotating rod 407 can rotate inside the rotating plate 406, and both ends of the rotating rod 407 can move and rotate in the sliding groove 106. In use, the screw 303 can be rotated by turning the handle 304. The forward or reverse rotation of the screw 303 can raise or lower the lifting plate 401. By moving the lifting plate 401 downward, the rotating plate 406 can be moved accordingly. The lifting plate 401 rotates, causing the right end of the rotating plate 406 to continuously approach and contact the inner wall of the box 101. Then, unscreened silica gel particles are fed into the box 101 through the feed pipe 102. Under gravity, the silica gel particles move downwards and fall onto the rotating plate 406. After feeding is complete, the lifting plate 401 rises, creating a gap between the right end of the rotating plate 406 and the inner wall of the box 101. This allows the silica gel particles to fall through the gap onto the sieve plate 5 for screening. When screening smaller silica gel particles, the lifting plate 401 rises a shorter distance. The design minimizes the gap between the right end of the rotating plate 406 and the inner wall of the housing 101, and also minimizes the tilt angle of the rotating plate 406. This ensures that smaller silica particles can pass through the gap at a slower speed, preventing them from clogging the screen holes 503 due to excessively fast feeding speed. When screening larger silica particles, the lifting plate 401 rises a greater distance, resulting in a larger gap between the right end of the rotating plate 406 and the inner wall of the housing 101, and a larger tilt angle of the rotating plate 406. This ensures that larger silica particles can pass through the gap at a faster speed, increasing the discharge rate of larger silica particles per unit time and improving the screening efficiency for larger silica particles.

[0021] Furthermore, the outer casing 1 includes a casing 101. A feed pipe 102 is fixedly connected to the upper part of the casing 101. A first discharge port 103 is provided on the left side of the casing 101 for discharging larger silica particles after screening. A second discharge port 105 is provided on the right side of the casing 101 for discharging smaller silica particles after screening. A guide plate 104 is fixedly connected to the lower part of the casing 101 for guiding the discharge of smaller silica particles after screening. Slide grooves 106 are provided on both the front and rear sides of the inner side of the casing 101 for moving and rotating the rotating rod 407.

[0022] Furthermore, the collection device 2 includes a placement shell 201 fixedly connected to both sides of the outer box 1. A collection box 202 is placed inside the placement shell 201. A handle 203 is fixedly connected to both the front and rear sides of the collection box 202. The collection box 202 is used to collect silica gel particles after screening.

[0023] Furthermore, the connecting frame 3 includes a fixed plate 301 fixedly connected to the upper left side of the inner side of the outer box 1. A guide rod 302 is fixedly connected between the fixed plate 301 and the outer box 1. The guide rod 302 is used to guide the lifting plate 401. A stud 303 is movably connected between the fixed plate 301 and the inner side of the outer box 1. A handle 304 is fixedly connected to the upper side of the stud 303. By rotating the handle 304, the stud 303 can be rotated. By rotating the stud 303 in the forward or reverse direction, the lifting plate 401 can be lifted.

[0024] Furthermore, the sieve plate 5 includes a plate body 501 movably connected inside the placement frame 6. The plate body 501 has sieve holes 503 inside. Pull handles 502 are fixedly connected to both the front and rear sides of the plate body 501. Movable grooves 504 are provided on both the left and right sides of the plate body 501. The plate body 501 can be fixed by pressing the movable grooves 504 into the outside of the rubber strip 602. During sieving, larger silica particles fall along the plate body 501 through the first discharge port 103 into the collection box 202 on the left. Smaller silica particles fall through the sieve holes 503 onto the guide plate 104, and under the guidance of the guide plate 104, fall through the second discharge port 105 into the collection box 202 on the right.

[0025] Furthermore, the placement frame 6 includes a frame body 601 fixedly connected inside the outer box 1. Rubber strips 602 are fixedly connected to the left and right sides of the inner side of the frame body 601, so that the moving groove 504 of the plate body 501 can be aligned with the rubber strips 602 to put the plate body 501 into the frame body 601. Under the action of the rubber strips 602, the plate body 501 can be kept stable. The plate body 501 can be pulled out by pulling the handle 502 outward, which makes it easy to replace the plate body 501 with different sizes of screen holes 503.
