Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of refractory material processing equipment, specifically to a refractory material raw material particle grading and screening device. Background Technology
[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃, and are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. In the production process of refractory materials, the raw materials need to be crushed. The crushed raw material particles are of varying sizes. To ensure the quality of subsequent products, the raw material particles need to be graded and screened to separate particles of different sizes.
[0003] In existing technologies, refractory material raw material particle grading and screening devices mostly use single-layer or double-layer vibrating screens for screening. However, in actual design, current vibrating screens lack suitable separating discharge components at the discharge position, which easily leads to confusion when the screened refractory raw materials are discharged from the tail end. At the same time, during screening and feeding, the raw materials may clump together, which can easily cause blockage of the screen plate after entering the vibrating screen, affecting the screening efficiency. In addition, the screen plate of the vibrating screen is usually installed inside the vibrating screen by adding screws, which makes it inconvenient to perform regular cleaning and maintenance of the screen plate.

The limiting holes and the mounting holes are all through holes and are coaxially aligned along the height direction of the screen plate. At the same time, each set of coaxially aligned mounting holes and limiting holes is coaxially inserted with a limiting rod in a sliding fit.
[0015] Preferably, each of the limiting rods has a handle coaxially fixed to its top end. The portion of the limiting rod located between the bottom of the corresponding handle and the top of the U-shaped guide rail is coaxially fitted with a spring in a clearance fit, and the two ends of the spring are respectively fixedly connected to the corresponding handle and the limiting rod.
[0016] Preferably, there are two limiting rods at the front position of each U-shaped guide rail.

[0019] In practical application, the aforementioned refractory material raw material particle grading and screening device features a discharge assembly with guiding and separating discharge functions, located at the front opening of the vibrating screen body. The two discharge pipes of this assembly correspond to the front edges of the two screen plates, and are vertically staggered and separated by a partition. This method of discharging material from both sides via the two discharge pipes of the discharge assembly achieves separate discharge of the screened material, preventing confusion and improving the screening efficiency of refractory materials. The selection of effect and efficiency is achieved through the sliding engagement of the sieve plate with the U-shaped guide rail of the quick-release assembly along the length direction and the sliding engagement of the limiting rod with the limiting hole along the height direction. This allows the sieve plate to be detachably assembled inside the vibrating screen body. The assembly method of the sieve plate inside the vibrating screen body is simple and easy to implement, thus facilitating the quick assembly of the sieve plate inside the vibrating screen body for particle classification and screening of refractory materials. Furthermore, after opening the sealed box door to open the front of the vibrating screen body, it is only necessary to pull up the limiting rod to disengage it from the limiting hole. The screen plates can then slide forward along the length of the U-shaped guide rail and separate from each other, allowing them to be removed from the front of the vibrating screen body. The method of separating the screen plates inside the vibrating screen body is simple and easy to implement, facilitating quick removal of the screen plates for regular cleaning and maintenance. Furthermore, the rear top surface of the vibrating screen body is equipped with a feeding assembly that prevents clogging and breaks up refractory material agglomerates. The feeding assembly's drive motor rotates the material wing plates, effectively preventing refractory material agglomerates from entering the vibrating screen body. Before the vibrating screen body is installed, a dispersion operation is performed to prevent refractory materials from clumping and falling directly to the top of the screen plate, which would then block the screen plate. This helps to ensure efficient particle grading and screening of refractory materials. Furthermore, since the outer edges of the material wing plates are covered with flexible scrapers made of buffer material, and these flexible scrapers can adhere to the inner wall of the feed pipe during rotation, the drive motor drives the material wing plates to rotate, allowing the flexible scrapers to scrape the inner wall of the feed pipe, preventing refractory materials from sticking to the inner wall of the flexible scrapers and ensuring that the refractory materials fall smoothly.
[0020] The beneficial effects are as follows: 1. The present invention has a discharge component with guiding and separating discharge function at the front opening of the vibrating screen body. At the same time, the two discharge pipes of the discharge component correspond to the front edges of the two screen plates respectively, and the two discharge pipes are staggered in the vertical direction and separated by the partition. By means of the discharge of the two discharge pipes of the discharge component at the two sides, the material to be screened can be separated and discharged, avoiding confusion, which helps to improve the screening effect and efficiency of refractory materials.
[0021] 2. By sliding the screen plate and the quick-release assembly along the length of the U-shaped guide rail and sliding the limiting rod and the limiting hole along the height, the screen plate can be detachably assembled inside the vibrating screen body. The assembly method of the screen plate inside the vibrating screen body is simple and easy to realize, which makes it convenient to quickly assemble the screen plate inside the vibrating screen body for particle classification and screening of refractory materials.
[0022] 3. After opening the sealed box door to open the front of the vibrating screen body, simply pull up the limit rod to disengage it from the limit hole, and the screen plate can slide forward along the length of the U-shaped guide rail and separate from each other. This allows the screen plate to be removed from the front of the vibrating screen body.

This helps to ensure efficient particle classification and screening of refractory materials.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0038] See Figures 1-9As shown, this utility model provides a refractory material raw material particle grading and screening device, including a vibrating screen body 1. The screening and sliding direction of the vibrating screen body 1 is inclined downward from back to front along the longitudinal direction. The vibrating screen body 1 is provided with a double-layer screen plate 101 along its own screening and sliding direction. The screen plate 101 is unfolded and arranged in the upper and lower positions inside the vibrating screen body 1 so as to divide the interior of the vibrating screen body 1 into three layers of screening space through the screen plate 101. Quick-release components 4 are assembled on both sides of the screen plate 101 inside the vibrating screen body 1. The screen plate 101 is detachably fixed inside the vibrating screen body 1 via the quick-release components 4. Specifically, each quick-release component 4 includes a U-shaped guide rail 405 and a limiting hole 401. The U-shaped guide rail 405 is fixedly installed on both sides of the screen plate 101 inside the vibrating screen body 1, and the U-shaped guide rail 405 is arranged along the inclined direction of the screen plate 101. At the same time, the screen plate 101 is locked in front of the two U-shaped guide rails 405 in a sliding fit along the length direction. Several limiting holes 401 are vertically opened on the front of both sides of the top surface of the screen plate 101. Several mounting holes 402 are vertically opened on the front of the top surface of the U-shaped guide rail 405. The limiting holes 401 and the mounting holes 402 are through holes and are respectively arranged along the height of the screen plate 101. The screen plates are aligned coaxially in the dimensional direction. Furthermore, the mounting holes 402 and limiting holes 401 of each coaxial alignment are coaxially inserted with limiting rods 406 via a sliding fit. This arrangement allows the screen plates 101 to be detachably assembled inside the vibrating screen body 1 through the sliding fit between the screen plate 101 and the U-shaped guide rail 405 of the quick-release assembly 4 along the length direction, and the sliding fit between the limiting rods 406 and the limiting holes 401 along the height direction. Simultaneously, after opening the sealing box door 201 to open the front of the vibrating screen body 1, simply pulling up the limiting rods 406 to disengage them from the limiting holes 401 allows the screen plates 101 to slide forward along the length direction of the U-shaped guide rail 405 and separate from each other. This enables the screen plates 101 to be removed from the front of the vibrating screen body 1. The assembly and disassembly of the screen plates 101 inside the vibrating screen body 1 is simple and easy to implement.
[0039] See Figures 1-7As shown, the front of the vibrating screen body 1 is open and equipped with a discharge assembly 2 that has a guiding and separating discharge function. The discharge assembly 2 is used to separate and discharge the screened material. Specifically, the discharge assembly 2 includes a sealing door 201 and a discharge pipe 203. The sealing door 201 is sealed at the front of the vibrating screen body 1. One side of the sealing door 201 is rotatably installed with the vibrating screen body 1 via a hinge 202. The other side of the sealing door 201 is equipped with a lock 205 at the joint position with the vibrating screen body 1, so that the sealing door 201 can be repeatedly opened and closed. The two front sides of the sealing door 201 are fixedly extended with discharge pipes 203 along the inclined direction of the screen plate 101. The two discharge pipes 203 are vertically staggered and their rear bottom edges correspond to the bottom edges of the two screen plates 101 respectively. The purpose of this arrangement is to separate and discharge the screened material by means of the two discharge pipes 203 discharging material on both sides, so as to avoid confusion.
[0040] See Figures 1-9 As shown, a feeding assembly 3 with anti-blocking and refractory material agglomeration functions is assembled on the rear top surface of the vibrating screen body 1. This feeding assembly 3 is used to disperse refractory material agglomerates before they enter the vibrating screen body 1. Specifically, the feeding assembly 3 includes a feeding pipe 302 and a feeding hopper 301. The feeding pipe 302 is vertically and fixedly connected to the rear top surface of the vibrating screen body 1, and the top end of the feeding pipe 302 is fixedly connected to the feeding hopper 301. A drive motor 305 and a bearing seat 308 are fixedly installed on both sides of the outer surface of the feeding pipe 302, respectively. The motor shaft 304 of the drive motor 305 is in a sliding fit. A drive shaft 303 is inserted into the feed pipe 302 and coaxially fixed thereon. The other end of the drive shaft 303 passes through the outside of the feed pipe 302 in a sliding fit and is coaxially fixed with the inner ring of the bearing built into the bearing housing 308. A plurality of radially outwardly extending material wing plates 306 are fixed on the part of the drive shaft 303 located between the two inner sides of the feed pipe 302. The reason for this arrangement is that by using the drive motor 305 of the feed assembly 3 to drive the material wing plates 306 to rotate, the refractory material clumps can be broken up and dispersed before entering the vibrating screen body 1, so as to prevent the refractory material clumps from falling directly to the top of the screen plate 101 and blocking the screen plate 101.
[0041] See Figures 1-9As shown, the following optimizations have been made to this application. Specifically, the vibrating screen body 1 is an eccentric vibrating screener, so that the vibrating screen body 1 can achieve good and stable grading and screening effect of refractory raw material particles. Optionally, a vertically arranged discharge pipe 102 is connected to the front bottom of the vibrating screen body 1, and a cap 103 is detachably attached to the bottom end of the discharge pipe 102 via a threaded connection. This arrangement facilitates the discharge of refractory raw materials screened in the third screening space to the outside through the discharge pipe 102. Furthermore, a partition 204 is vertically fixed in the middle of the front of the sealed box door 201, and the two discharge pipes 203 are separated by the partition 204, so as to stably separate the two discharge pipes 203 with the help of the partition 204.
[0042] See Figures 1-9 As shown, each limiting rod 406 has a handle 404 coaxially fixed to its top. The portion of the limiting rod 406 located between the bottom of the corresponding handle 404 and the top of the U-shaped guide rail 405 is coaxially fitted with a spring 403 in a clearance fit. Both ends of the spring 403 are fixedly connected to the corresponding handle 404 and the limiting rod 406, respectively. This arrangement facilitates pulling the limiting rod 406 by applying force with the handle 404, and also allows the limiting rod 406 to automatically return to its original position using the spring 403. Furthermore, there are two limiting rods 406 at the front of each U-shaped guide rail 405, ensuring that the screen plate 101 can be easily removed by having at least two people stand on each side, preventing accidental removal of the screen plate 101. Furthermore, the bulk material wing plates 306 are all rectangular plates with multiple transversely arranged material passage openings 309. The outer edge of each bulk material wing plate 306 is covered with a flexible scraper 307 of buffer material. When the bulk material wing plate 306 is flipped, the outer edge of the flexible scraper 307 can come into contact with the inner wall of the feed pipe 302. With this configuration, by using the drive motor 305 to drive the bulk material wing plate 306 to rotate, the flexible scraper 307 can scrape the inner wall of the feed pipe 302, preventing the refractory material from sticking to the inner wall of the flexible scraper 307 and ensuring that the refractory material falls smoothly.
[0043] With the above structure, in practical use, a discharge assembly 2 with guiding and separating discharge function is combined and arranged at the front opening of the vibrating screen body 1. The two discharge pipes 203 of the discharge assembly 2 correspond to the front edges of the two screen plates 101, and the two discharge pipes 203 are vertically staggered and separated by a partition 204. By discharging material from both sides through the two discharge pipes 203 of the discharge assembly 2, the screened material can be separated and discharged, avoiding confusion and improving the screening effect and efficiency of refractory materials. Furthermore, because the material passes through the screen plates... The sliding engagement of the U-shaped guide rail 405 of the quick-release assembly 101 along the length direction and the sliding engagement of the limiting rod 406 with the limiting hole 401 along the height direction allow the screen plate 101 to be detachably assembled inside the vibrating screen body 1. This assembly method of the screen plate 101 inside the vibrating screen body 1 is simple and easy to implement, facilitating the quick assembly of the screen plate 101 for particle grading and screening of refractory materials. Furthermore, after opening the sealing door 201 to open the front of the vibrating screen body 1, simply pulling up the limiting rod 406 to disengage it from the limiting hole 401 allows the screen plate 101 to slide along the U-shaped guide rail 405 along the length direction and the limiting rod 406 with the limiting hole 401 along the height direction. The guide rails 405 slide forward and separate from each other along their length, allowing the screen plate 101 to be removed from the front of the vibrating screen body 1. The method of separating the screen plate 101 inside the vibrating screen body 1 is simple and easy to implement, facilitating the quick removal of the screen plate 101 from the vibrating screen body 1 for regular cleaning and maintenance. Furthermore, the rear top surface of the vibrating screen body 1 is equipped with a feeding assembly 3 that has anti-blocking and refractory material agglomeration functions. The feeding assembly 3's drive motor 305 drives the material wing plate 306 to rotate, thus breaking up refractory material agglomerates before they enter the vibrating screen body 1. The dispersed operation prevents refractory materials from clumping and falling directly onto the top of the sieve plate 101, thus blocking the sieve plate 101. This helps ensure efficient particle classification and screening of refractory materials. Furthermore, since the outer edges of the material wing plates 306 are covered with flexible scrapers 307 made of buffer material, and the flexible scrapers 307 can adhere to the inner wall of the feed pipe 302 during rotation, the flexible scrapers 307 can scrape the inner wall of the feed pipe 302 by the drive motor 305 driving the material wing plates 306 to rotate. This prevents the refractory materials from sticking to the inner wall of the flexible scrapers 307, ensuring that the refractory materials fall smoothly.
[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
