Description

Technical Field

[0001] This utility model relates to the field of micronized silica gel production and processing technology, and in particular to a micronized silica gel screening and feeding adjustment device for a vibrating screen. Background Technology

[0002] Micronized silica gel (also known as gaseous silica gel or silica powder) is a high-purity, highly dispersible inorganic non-metallic powder characterized by small particle size, large specific surface area, and strong adsorption. It is commonly used in pharmaceuticals, food, and chemical industries. In the production and processing of micronized silica gel, a vibrating screen (a screening device that uses a vibrating motor to generate three-dimensional vortex force) plays a crucial role, enabling control over the particle size of the micronized silica gel, removal of impurities, and dispersion of the powder.

[0003] Patent number CN218743163U relates to a novel rotary vibrating screen, comprising a rotary vibrating screen body, a screen mesh fixedly installed inside the rotary vibrating screen body, a discharge port on the side of the rotary vibrating screen body, a dust cover fixedly installed on the top of the rotary vibrating screen body, a feed inlet on the dust cover, and an adjusting device at the feed inlet. The adjusting device includes a base plate, a baffle, and a lever. The base plate is horizontally fixed inside the feed inlet and has several leakage holes. A baffle corresponding to blocking the leakage holes is rotatably installed above the base plate. The lever passes through the outer wall of the feed inlet and is fixedly connected to the side of the baffle. An opening for the lever to rotate is provided on the outer wall of the feed inlet. This utility model aims to provide a novel rotary vibrating screen that can control the amount of rice fed into the screen, improve the screening effect, and increase screening efficiency.

[0004] However, the aforementioned novel vibrating screen still has the following shortcomings:

[0005] Although the above-mentioned device can adjust the size of the material leakage hole and control the feed rate of the vibrating screen by rotating the lever to drive the baffle to rotate, some material still accumulates on the bottom plate and the horizontal surface of the baffle, which is difficult to remove and cannot be discharged automatically. At the same time, due to the high friction between the micro-powder silica particles, they are easy to agglomerate, and the accumulation and bridging can easily lead to poor subsequent discharge. In view of this, we propose a micro-powder silica screening and feeding vibrating screen feed adjustment device. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a feeding adjustment device for a micro-powder silica gel screening and feeding vibrating screen. This device solves the technical problems that although the current device can adjust the size of the leakage hole and control the feeding amount of the vibrating screen by rotating the lever to drive the baffle to rotate, some material still accumulates on the bottom plate and the horizontal surface of the baffle, which is difficult to remove and cannot be discharged independently. At the same time, due to the high friction between micro-powder silica gel particles, they are easy to agglomerate, and the accumulation and bridging can easily lead to poor subsequent feeding.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a feeding adjustment device for a micro-powder silica gel sieving and feeding rotary vibrating screen is designed and applied to a micro-powder silica gel rotary vibrating screen. The top of the micro-powder silica gel rotary vibrating screen is fixedly provided with a feeding port, a set of auxiliary mechanisms are symmetrically provided on the surface of the feeding port, and a feeding adjustment mechanism is provided on the top of the feeding port.

[0008] The feeding adjustment mechanism includes a material cylinder that fits snugly against the top of the feed inlet. A set of guide blocks are symmetrically fixed on both sides of the surface of the material cylinder. A flow guide frame is fixedly connected inside the material cylinder. A brush frame is fixedly sleeved on the outside of the flow guide frame. Several brush clusters are evenly distributed at the bottom of the brush frame. A set of adjustment plates are symmetrically attached to the bottom of the flow guide frame. A set of support cylinder frames are symmetrically fixed at the bottom of the set of adjustment plates. The support cylinder frames are connected to the material cylinder through a hydraulic cylinder.

[0009] Preferably, the flow guide frame is in the shape of a hollow hexagonal frustum, and the bottom of the several brush clusters is flush with the bottom of the flow guide frame.

[0010] Preferably, the adjusting plate has an inclined groove inside, the adjusting plate and the support cylinder are integrally formed, the piston rod in the hydraulic cylinder has the same length as the depth of the groove in the support cylinder, and one end of the piston rod in the hydraulic cylinder is fixedly connected to the inner wall of the support cylinder.

[0011] Preferably, when the piston rod in the hydraulic cylinder retracts, the inner wall of the support frame is in contact with the outer wall of the hydraulic cylinder.

[0012] Preferably, the auxiliary mechanism includes a guide slot frame, which is fixed to the surface of the feed inlet. A limiting cylinder frame is fixed to the side surface of the guide slot frame. A limiting rod passes through the inside of the limiting cylinder frame. A limiting ring plate is fixedly sleeved on the surface of the limiting rod. A spring is provided on one side of the limiting ring plate.

[0013] Preferably, the outer end of the limiting rod is spherical, and the inner end of the limiting rod passes through the side of the guide slot frame.

[0014] Preferably, the limiting rod is formed into an elastic structure by a limiting ring plate, a spring and a limiting cylinder, and the guide block surface is provided with a groove that matches the inner end of the limiting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model effectively drives the support cylinder and adjusting plate to move horizontally through a hydraulic cylinder, thereby adjusting the spacing between a set of adjusting plates, which facilitates the control of the feeding amount of micro-powdered silica gel. Since the support cylinder isolates the piston rod in the hydraulic cylinder from the external environment, it avoids the adhesion of micro-powdered silica gel particles to the piston rod surface, reducing the possibility of hydraulic cylinder jamming. The inclined groove opened inside the adjusting plate facilitates the direct sliding of micro-powdered silica gel particles, preventing the accumulation of micro-powdered silica gel particles on the surface of the adjusting plate. When the adjusting plate resets and continues to close the bottom of the guide frame, several brush clusters effectively sweep the top horizontal surface of the adjusting plate, preventing jamming when the top of the adjusting plate is in contact with the bottom of the guide frame.

[0017] 2. In this utility model, pulling the limiting rod outward causes the inner end of the limiting rod to disengage from the guide groove inside the guide groove frame, making it easier for the bottom of the guide block to smoothly engage inside the guide groove frame. After releasing the limiting rod, the inner end of the limiting rod pops out under the influence of the spring rebound force and effectively engages in the groove on the surface of the guide block, realizing the rapid limiting and fixing of the guide block, and avoiding the gap between the feeding adjustment mechanism and the feeding port when the micro-powder silica gel vibrating screen vibrates.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] A feeding adjustment device for a micro-powder silica gel sieving and discharging vibrating screen, see [link / reference]. Figures 1 to 6 It is applied to the micro-powder silicone rotary vibrating screen 1. The top of the micro-powder silicone rotary vibrating screen 1 is fixedly provided with a feed inlet 2. A set of auxiliary mechanisms 3 are symmetrically provided on the surface of the feed inlet 2. The top of the feed inlet 2 is provided with a feed adjustment mechanism 4.

[0029] The feeding adjustment mechanism 4 includes a feed cylinder 401, which is fitted to the top of the feed inlet 2. A set of guide blocks 402 are symmetrically fixed on both sides of the surface of the feed cylinder 401. A flow guide frame 403 is fixedly connected inside the feed cylinder 401. A brush frame 404 is fixedly sleeved on the outside of the flow guide frame 403. Several brush clusters 405 are evenly distributed at the bottom of the brush frame 404. The flow guide frame 403 is hollow hexagonal truncated pyramid. The bottom of the several brush clusters 405 is flush with the bottom of the flow guide frame 403. A set of adjustment plates 406 are symmetrically attached to the bottom of the flow guide frame 403. A set of support cylinders 407 is symmetrically fixed at the bottom of 06. The support cylinders 407 are connected to the material cylinder 401 through a hydraulic cylinder 408. Furthermore, an inclined groove is opened inside the adjusting plate 406. The adjusting plate 406 and the support cylinders 407 are integrally formed. The length of the piston rod in the hydraulic cylinder 408 is the same as the depth of the inner groove of the support cylinder 407. One end of the piston rod in the hydraulic cylinder 408 is fixedly connected to the inner wall of the support cylinder 407. Furthermore, when the piston rod in the hydraulic cylinder 408 retracts, the inner wall of the support cylinder 407 fits against the outer wall of the hydraulic cylinder 408. This invention effectively drives the support cylinder 407 and the adjusting plate 406 to move horizontally via the hydraulic cylinder 408, thereby adjusting the spacing between a set of adjusting plates 406. This facilitates control over the amount of micro-powdered silica gel being fed. Since the support cylinder 407 isolates the piston rod in the hydraulic cylinder 408 from the external environment, it prevents micro-powdered silica gel particles from adhering to the surface of the piston rod, reducing the possibility of jamming in the hydraulic cylinder 408. The inclined grooves inside the adjusting plate 406 facilitate the direct sliding of micro-powdered silica gel particles, preventing them from accumulating on the surface of the adjusting plate 406. When the adjusting plate 406 resets and continues to seal the bottom of the guide frame 403, several brush clusters 405 effectively sweep the top horizontal surface of the adjusting plate 406, preventing jamming when the top of the adjusting plate 406 is in contact with the bottom of the guide frame 403.

[0030] It is worth noting that the auxiliary mechanism 3 includes a guide slot frame 301, which is fixed to the surface of the feed inlet 2. A limiting cylinder frame 302 is fixed to the side surface of the guide slot frame 301. A limiting rod 303 passes through the inside of the limiting cylinder frame 302. The outer end of the limiting rod 303 is spherical, and the inner end of the limiting rod 303 passes through the side of the guide slot frame 301. A limiting ring plate 304 is fixedly sleeved on the surface of the limiting rod 303. A spring 305 is provided on one side of the limiting ring plate 304. Furthermore, the limiting rod 303 forms an elastic structure with the limiting cylinder frame 302 through the limiting ring plate 304 and the spring 305. A groove matching the inner end of the limiting rod 303 is opened on the surface of the guide block 402. In this invention, pulling the limiting rod 303 outward causes the inner end of the limiting rod 303 to disengage from the guide groove inside the guide slot frame 301, making it easier for the bottom of the guide block 402 to smoothly engage inside the guide slot frame 301. After releasing the limiting rod 303, the inner end of the limiting rod 303 pops out and effectively engages in the slot on the surface of the guide block 402 due to the rebound force of the spring 305, thereby achieving rapid limiting and fixing of the guide block 402 and preventing gaps from forming between the feeding adjustment mechanism 4 and the feed inlet 2 when the micro-powder silica gel vibrating screen 1 vibrates.

[0031] Working principle: Pulling the limiting rod 303 outward causes its inner end to disengage from the guide groove inside the guide frame 301, facilitating the smooth insertion of the bottom of the guide block 402 into the guide frame 301. Then, releasing the limiting rod 303 causes its inner end to pop out and engage in the groove on the surface of the guide block 402 due to the rebound force of the spring 305, achieving rapid limiting and fixing of the guide block 402. This prevents gaps from forming between the feeding adjustment mechanism 4 and the feed inlet 2 when the micro-powder silica gel vibrating screen 1 vibrates. Then, the hydraulic cylinder 408 drives the support frame 407 and the adjusting plate 406 to move horizontally, thereby achieving the adjustment of a set of adjusting plates 406. The spacing can be adjusted to facilitate control of the amount of micro-powdered silica gel fed. Since the support frame 407 isolates the piston rod in the hydraulic cylinder 408 from the external environment, it prevents micro-powdered silica gel particles from adhering to the surface of the piston rod, reducing the possibility of jamming in the hydraulic cylinder 408. The inclined groove inside the adjusting plate 406 allows the micro-powdered silica gel particles to slide directly down, preventing them from accumulating on the surface of the adjusting plate 406. Subsequently, when the adjusting plate 406 resets and continues to seal the bottom of the guide frame 403, several brush clusters 405 sweep the top horizontal surface of the adjusting plate 406 to prevent jamming when the top of the adjusting plate 406 is in contact with the bottom of the guide frame 403.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
