Description

Technical Field

[0001] The utility model belongs to the technical field of circular vibrating screens, and particularly relates to a sieve plate for a circular vibrating screen. Background Art

[0002] A circular vibrating screen is a multi-layer and efficient new vibrating screen that makes circular vibrations. Its working principle is that the rotation of the main shaft of the vibrator is driven by an electric motor. By using the centrifugal inertia force of the unbalanced weights on the vibrator, the sieve box is forced to vibrate, so that the materials on the sieve surface are subjected to an upward acting force and are thrown up. After advancing a certain distance, they fall back to the sieve surface again. Such repeated movements complete the screening process of the materials. The circular vibrating screen has the advantages of a long material screening line, multiple screening specifications, reliable structure, high screening efficiency, durability, and convenient maintenance, and is widely used in the fields of mines, building materials, transportation, energy, chemical engineering, etc.

[0003] The sieve hole sizes of the existing sieve plates of circular vibrating screens are fixed and cannot be adjusted, resulting in the circular vibrating screen being unable to be applicable to the screening of materials with different particle sizes, and the applicability is relatively low. For this reason, sieve plates with adjustable sieve holes have appeared on the market. For example, the Chinese utility model patent with the publication number: CN219442475U discloses a sieve plate, which adjusts the shielding area of the sieve holes by adjusting the adjusting plate using the convex platform, so that large-particle-size cement particles cannot pass through the sieve holes, and thus the screening of cements with different finenesses can be adjusted. To a certain extent, it can meet the use requirements. However, since the convex platform is fixedly connected to the adjusting plate, the shielding area of the convex platform for the sieve holes on the sieve plate tends to be the same, and it cannot be flexibly applied to the actual use requirements, and there are certain limitations.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a sieve plate for a circular vibrating screen.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a sieve plate for a circular vibrating screen, which can solve the problem that the sieve holes of the sieve plate cannot be adjusted more flexibly.

[0007] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the present utility model is as follows:

[0008] A sieve plate for a circular vibrating screen includes: a sieve plate main body and a hole adjusting mechanism;

[0009] A number of uniformly distributed sieve holes are provided through the sieve plate main body;

[0010] The hole adjusting mechanism is installed on the sieve plate main body and corresponds to the sieve holes. The hole adjusting mechanism is used to block the sieve holes and thus adjust the discharging aperture of the sieve holes.

[0011] In one or more embodiments of the present invention, the hole adjusting mechanism includes a pair of first guide rails. The pair of first guide rails are symmetrically installed on the sieve plate main body. The first guide rails are used to accommodate sliders, and the sliders can move within the first guide rails, and thus the position of the mounting plate can be adjusted.

[0012] A slider is slidably arranged in the first guide rail, and the slider is used to connect the mounting plate.

[0013] In one or more embodiments of the present invention, the length of the slider is less than the length of the first guide rail and greater than the distance between a pair of adjacent sieve holes, so that the mounting plate can be stably installed on the sieve plate main body through the mutual cooperation of the first guide rail and the slider.

[0014] In one or more embodiments of the present invention, a mounting plate is fixedly connected to the slider, and the mounting plate is used to mount a plurality of shielding plates.

[0015] A screw rod is rotatably connected to the first guide rail. The screw rod is threadedly connected to the slider. When the screw rod rotates, the slider can move within the first guide rail under the action of the thread to adjust the position of the mounting plate. When the screw rod does not rotate, the mounting plate is fixed through the threaded action of the slider and the screw rod to ensure the shielding effect of the mounting plate on the sieve holes.

[0016] In one or more embodiments of the present invention, the length of the mounting plate is less than the length of the sieve plate main body and greater than the distance between a pair of sieve holes that are far away from each other on the same straight line, which is convenient for mounting a plurality of shielding plates.

[0017] In one or more embodiments of the present invention, a plurality of uniformly distributed fine adjustment grooves are provided on the mounting plate, and the fine adjustment grooves are used to mount the shielding plates.

[0018] Guide rods are fixedly connected in the fine adjustment grooves. The guide rods are used to guide the movement of the shielding plates, so that when the shielding plates move, both ends of the shielding plates are not likely to deviate, and thus the shielding effect of the shielding plates on the sieve holes can be ensured.

[0019] In one or more embodiments of the present invention, the length of the fine adjustment groove is greater than twice the diameter of the sieve hole. When the shielding plate moves to one side of the fine adjustment groove, the sieve hole will not be blocked by the shielding plate. When the shielding plate moves to the other side of the fine adjustment groove, the sieve hole will be completely blocked by the shielding plate. Thus, it is convenient to adjust the aperture size of the sieve hole so as to screen materials with different particle sizes.

[0020] In one or more embodiments of the present utility model, a shielding plate is slidably connected to the guiding rod. The width of the shielding plate is greater than the diameter of the sieve holes and less than the distance between a pair of adjacent sieve holes. The shielding plate is used to block the sieve holes so as to adjust the aperture of the sieve holes, enabling the sieve plate main body to screen materials of different particle sizes.

[0021] In one or more embodiments of the present utility model, a locking screw is threadedly connected to the shielding plate. One end of the locking screw passes through the mounting plate. By tightening the locking screw, the mounting plate and the shielding plate can be fixed.

[0022] A clearance groove matching the locking screw is provided on the mounting plate. When the shielding plate moves in the fine adjustment groove, the locking screw can move in the clearance groove, enabling the locking screw to fix the mounting plate and the shielding plate.

[0023] In one or more embodiments of the present utility model, a scale groove is provided on the mounting plate. The scale groove corresponds to the shielding plate, facilitating the knowledge of the moving distance of the shielding plate in the fine adjustment groove, so as to better block the sieve holes and thus facilitate the screening of materials of different particle sizes.

[0024] Compared with the prior art, a sieve plate for a circular vibrating screen of the present utility model can flexibly shield the sieve holes on the sieve plate according to the materials, and thus can complete the screening work of different materials to meet different usage requirements.

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] As Figures 1 to 5 shown, a sieve plate for a circular vibrating screen in an embodiment of the present utility model includes a sieve plate main body 1 and a hole adjusting mechanism 2.

[0035] Among them, a plurality of uniformly distributed sieve holes 101 are provided through the sieve plate main body 1. Materials with a particle size smaller than the sieve holes 101 can pass through the sieve holes 101, and thus the screening of materials can be realized.

[0036] As Figures 1 to 5 shown, the hole adjusting mechanism 2 is installed on the sieve plate main body 1 and corresponds to the sieve holes 101. The hole adjusting mechanism 2 is used to block the sieve holes 101, and thus is used to adjust the discharge aperture of the sieve holes 101 in order to screen materials with different particle sizes.

[0037] Among them, the hole adjusting mechanism 2 includes a pair of first guide rails 201. The pair of first guide rails 201 are symmetrically installed on the sieve plate main body 1. The first guide rails 201 are used to accommodate the slide blocks 202. The slide blocks 202 can move within the first guide rails 201, and thus the position of the mounting plate 203 can be adjusted.

[0038] In addition, the slide blocks 202 are slidably arranged in the first guide rails 201, and the slide blocks 202 are used to connect the mounting plate 203.

[0039] Preferably, the length of the slide block 202 is less than the length of the first guide rail 201 and greater than the distance between a pair of adjacent sieve holes 101. Through the mutual cooperation of the first guide rail 201 and the slide block 202, the mounting plate 203 can be stably installed on the sieve plate main body 1.

[0040] Specifically, a mounting plate 203 is fixedly connected to the slider 202, and the mounting plate 203 is used to mount a number of shielding plates 207.

[0041] Preferably, the length of the mounting plate 203 is less than the length of the sieve plate main body 1 and greater than the distance between a pair of sieve holes 101 that are far away from each other on the same straight line, ensuring that the shielding plate 207 can shield the sieve holes 101.

[0042] In addition, a screw rod 204 is rotatably connected to the first guide rail 201, and the screw rod 204 is threadedly connected to the slider 202. When the screw rod 204 is rotated, the slider 202 can move within the first guide rail 201 under the action of the thread, and thus the position of the mounting plate 203 can be adjusted. When the screw rod 204 is not rotated, the mounting plate 203 is fixed through the threaded action between the slider 202 and the screw rod 204, ensuring the shielding effect of the mounting plate 203 on the sieve holes 101.

[0043] As Figures 1 to 5 shown, a number of uniformly distributed fine adjustment slots 205 are provided on the mounting plate 203, and the fine adjustment slots 205 are used to mount the shielding plates 207, so that different shielding plates 207 can shield different areas of the sieve holes 101. A guide rod 206 is fixedly connected in the fine adjustment slot 205, and the guide rod 206 is used to guide the movement of the shielding plate 207, so that when the shielding plate 207 moves, the two ends of the shielding plate 207 are not prone to deviation, and thus the shielding effect of the shielding plate 207 on the sieve holes 101 can be ensured.

[0044] Preferably, the length of the fine adjustment slot 205 is greater than twice the diameter of the sieve hole 101. When the shielding plate 207 moves to one side of the fine adjustment slot 205, the sieve hole 101 will not be shielded by the shielding plate 207; when the shielding plate 207 moves to the other side of the fine adjustment slot 205, the sieve hole 101 will be completely shielded by the shielding plate 207, and thus different areas of the sieve holes 101 can be shielded to screen materials of different particle sizes.

[0045] Among them, a shielding plate 207 is slidably connected to the guide rod 206. The width of the shielding plate 207 is greater than the diameter of the sieve hole 101 and less than the distance between an adjacent pair of sieve holes 101. The shielding plate 207 is used to shield the sieve holes 101, so that the sieve plate main body 1 can screen materials of different particle sizes.

[0046] The shielding plate 207 in this application is movably connected to the mounting plate 203, and the shielding plate 207 can move within the fine adjustment slot 205. The moving distance of the shielding plate 207 can be observed through the scale slot 209, so that different shielding plates 207 can shield different areas of the sieve holes 101, as Figure 2As shown in the figure, the sieve plate body 1 can be used more flexibly to meet different usage requirements. At the same time, by covering different areas of the sieve holes 101 with different baffle plates 207, it is possible to screen materials with different particle sizes using only one sieve plate body 1, without the need to use multiple sieve plate bodies 1 for screening, thus reducing the cost of purchasing the sieve plate body 1.

[0047] In addition, a locking screw 208 is threadedly connected to the baffle plate 207. One end of the locking screw 208 passes through the mounting plate 203. By tightening the locking screw 208, the mounting plate 203 can be fixed to the baffle plate 207. An avoidance groove matching the locking screw 208 is provided on the mounting plate 203. When the baffle plate 207 moves in the fine adjustment groove 205, the locking screw 208 can move in the avoidance groove, enabling the locking screw 208 to fix the mounting plate 203 and the baffle plate 207.

[0048] Specifically, a scale groove 209 is provided on the mounting plate 203, corresponding to the baffle plate 207, which is convenient for knowing the moving distance of the baffle plate 207 in the fine adjustment groove 205, so as to better cover the sieve holes 101 and facilitate screening of materials with different particle sizes.

[0049] During specific use, when it is required that the blocking areas of the sieve holes 101 are the same, multiple baffle plates 207 are respectively moved to the same side of multiple fine adjustment grooves 205, and the mounting plate 203 and the baffle plates 207 are locked and fixed using the locking screws 208. By synchronously rotating a pair of screws 204, the slider 202 can move in the first guide rail 201 under the action of the thread, and then a pair of mounting plates 203 and multiple baffle plates 207 can be moved synchronously. Since the positions of different baffle plates 207 in different fine adjustment grooves 205 are the same, when multiple baffle plates 207 move the same distance, the areas of the sieve holes 101 blocked are the same.

[0050] When it is required that the blocking areas of multiple sieve holes 101 are different, loosen the locking screws 208 to enable the baffle plates 207 to move in the fine adjustment grooves 205. The moving distance of the baffle plates 207 can be observed through the scale grooves 209. When the baffle plates 207 move, they are also guided by the guide rods 206, making it difficult for the baffle plates 207 to deviate during movement. After the movement of the baffle plates 207 is completed, tighten the locking screws 208 to fix the baffle plates 207 to the mounting plate 203. Then synchronously rotate a pair of screws 204 to move the slider 202, a pair of mounting plates 203 and multiple baffle plates 207. Since the positions of different baffle plates 207 in different fine adjustment grooves 205 are different, when different baffle plates 207 move the same distance, the areas of the sieve holes 101 blocked will be different to meet the actual usage requirements of the sieve plate body 1.
