Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen technology, and in particular to a composite screen structure and a vibrating screen. Background Technology
[0002] In the nickel sulfate packaging production line, due to the particle size requirements of the finished nickel sulfate product, a linear vibrating screen is required to separate the finished nickel sulfate product into 8-mesh and 32-mesh sizes. Because the particle size difference between the finished nickel sulfate products corresponding to 8-mesh and 32-mesh is too large, and the wire diameter of the 32-mesh screen is relatively fine, the amplitude of the 32-mesh screen surface is too large during the process of the material falling from the 8-mesh screen to the 32-mesh screen. This can easily lead to irreversible damage such as inelastic deformation of the screen surface and enlargement of the screen holes. On average, the 32-mesh screen needs to be replaced every 4 to 5 days, resulting in a large waste of manpower and material resources.
[0003] Therefore, there is an urgent need for a composite screen structure and vibrating screen that can improve the lifespan of high-mesh screens. Utility Model Content
[0004] The purpose of this invention is to provide a composite screen structure and a vibrating screen, which aims to solve the technical problems of traditional high-mesh screens being easily deformed and damaged.
[0005] To achieve the above objectives, in a first aspect, this utility model provides a composite screen structure, comprising:
[0006] The support frame includes two parallel support vertical beams spaced apart and several support horizontal beams positioned between the two support vertical beams.
[0007] A high-mesh screen is installed on the upper surface of the support frame for screening and filtering materials of the corresponding particle size.
[0008] A low-mesh screen is installed on the lower surface of the support beam to buffer falling materials;
[0009] Several first support members are disposed on the lower surface of the high mesh screen, and their two ends are respectively connected to the inner sides of two support vertical beams;
[0010] Several second support members are disposed on the lower surface of the low mesh screen, and their two ends are respectively connected to the inner sides of two support vertical beams; the first support members and the second support members are staggered, and the support crossbeams divide the space between the high mesh screen and the low mesh screen into several screen cells.
[0011] As a further improvement to the above solution, the composite screen structure also includes:
[0012] Several ball-blocking rings are respectively set in the screen cell;
[0013] Several bouncing balls are respectively set in the screen cell, and cooperate with the ball-blocking ring to collide with the screen to increase the material's permeability.
[0014] As a further improvement to the above solution, the supporting vertical beam includes a channel steel beam and a plurality of supporting columns disposed in the channel steel beam groove, wherein the plurality of supporting columns are equally spaced along the length direction of the channel steel beam.
[0015] As a further improvement to the above solution, the supporting beam is made of rectangular tube, square tube or channel steel.
[0016] As a further improvement to the above solution, both the first support member and the second support member are steel strips with a preset thickness, which are set between the two support beams by means of screws or welding.
[0017] As a further improvement to the above solution, the high-mesh screen is detachably mounted on the upper surface of the support frame via an upper pressure strip; the low-mesh screen is detachably mounted on the lower surface of the support beam via a lower pressure strip.
[0018] Secondly, this utility model also provides a vibrating screen, including a composite screen structure as described in the first aspect.
[0019] Because this utility model adopts the above technical solutions, the beneficial effects of this application are as follows:
[0020] This utility model provides a composite screen structure. A high-mesh screen is provided on the upper surface of a support frame, and a low-mesh screen is provided on the lower surface of the support beam of the support frame. This two-layer composite screen arrangement allows the upper high-mesh screen to screen and filter materials of the corresponding particle size, while the lower low-mesh screen provides effective buffering and support when materials fall, preventing inelastic deformation of the screen surface and reducing its lifespan, without affecting the working efficiency of the high-mesh screen. Several first support members are provided on the lower surface of the high-mesh screen, and several second support members are provided on the lower surface of the low-mesh screen. These support members provide support for the corresponding screen surfaces, preventing large deformation of the screen when materials fall, which could lead to irreversible damage, thereby improving the lifespan of this composite screen structure.
[0021] In some preferred embodiments, the support beam divides the space between the high-mesh screen and the low-mesh screen into several screen cells. Several ball-blocking rings and several bouncing balls are provided in each screen cell. The ball-blocking rings and bouncing balls collide with the high-mesh screen and the low-mesh screen up, down, left, and right through the power of the swing screen to increase the material's permeability and ensure smooth machine operation. The use of bouncing balls for screen cleaning has lower costs and better screening efficiency.
[0022] In some preferred embodiments, the supporting vertical beam includes a channel steel beam and a plurality of supporting columns disposed within the channel steel beam. The plurality of supporting columns are equally spaced along the length direction of the channel steel beam. The arrangement of the plurality of supporting columns can effectively reduce the vibration amplitude of the screen caused by material falling onto the screen surface, alleviate the mechanical fatigue of the screen, and thus extend the service life of this composite screen structure.

[0036] Example 1
[0037] See Figures 1-4 This utility model provides a composite screen structure, comprising:
[0038] The support frame 1 includes two parallel support vertical beams 11 spaced apart and several support horizontal beams 12 disposed between the two support vertical beams 11.
[0039] A high-mesh screen 2 is set on the upper surface of the support frame 1 for screening and filtering materials of the corresponding particle size.
[0040] A low-mesh screen 3 is disposed on the lower surface of the supporting beam 12 to buffer falling materials; specifically, in this embodiment, the high-mesh screen 2 is a 32-mesh screen, and the low-mesh screen 3 is preferably a 12-mesh screen, which is disposed directly below the 32-mesh screen.
[0041] A plurality of first support members 4 are disposed on the lower surface of the high mesh screen 2, and their two ends are respectively connected to the inner side of two support vertical beams 11; the plurality of first support members 4 are disposed at intervals on the lower surface of the high mesh screen 2. In this embodiment, the first support members 4 are connected to the inner side of the two support vertical beams 11 by welding or screw fastening.
[0042] A plurality of second support members 5 are disposed on the lower surface of the low mesh screen 3, and their two ends are respectively connected to the inner sides of two support vertical beams 11; the plurality of second support members 5 are spaced apart on the lower surface of the low mesh screen 3, and the first support member 4 and the second support member 5 are staggered. In this embodiment, the second support member 5 also includes a bent portion, which is connected to the inner side of the two support vertical beams 11 by means of screws; during installation, the low mesh screen 3 can be placed on the lower surface of the support beam 12 first, and then the second support member 5 can be placed on the lower surface of the low mesh screen 3, and then the second support member 5 can be connected to the inner side of the two support vertical beams 11 by means of screws.
[0043] The supporting beam 12 divides the space between the high-mesh screen 2 and the low-mesh screen 3 into several screen cells. In this embodiment, each screen cell is also provided with several ball-blocking rings 6 and several bouncing balls 7. The ball-blocking rings 6 and the bouncing balls 7 collide with the high-mesh screen 2 and the low-mesh screen 3 up, down, left, and right through the power of the swing screen to increase the material's screen penetration rate, ensure smooth machine operation, and the use of bouncing balls 7 results in lower screen cleaning costs and better screening efficiency.
[0044] In this invention, a high-mesh screen 2 is provided on the upper surface of the support frame 1, and a low-mesh screen 3 is provided on the lower surface of the support beam 12 of the support frame 1. This two-layer composite screen arrangement allows the upper high-mesh screen 2 to screen and filter materials of the corresponding particle size, while the lower low-mesh screen 3 provides effective buffering and support when materials fall, preventing inelastic deformation of the screen surface and reducing its lifespan, without affecting the working efficiency of the high-mesh screen 2. Several first support members 4 are provided on the lower surface of the high-mesh screen 2, and several second support members 5 are provided on the lower surface of the low-mesh screen 3. Several support columns 112 can support the corresponding screen surface, preventing large deformation of the screen when materials fall, which could lead to irreversible damage, thereby improving the lifespan of this composite screen structure.
[0045] As a preferred embodiment, see Figure 3The supporting vertical beam 11 includes a channel steel beam 111 and a plurality of supporting columns 112 disposed in the channel steel beam 111. The plurality of supporting columns 112 are equally spaced along the length direction of the channel steel beam 111. Preferably, the supporting column 112 is a cylindrical segment, and the cylindrical segments are equally spaced in the cavity of the channel steel beam 111.
[0046] Several support columns 112 are arranged at equal intervals along the length of the channel steel beam 111; the arrangement of several support columns 112 can effectively reduce the vibration amplitude of the screen caused by material falling onto the screen surface, reduce the mechanical fatigue of the screen, and thus extend the service life of this composite screen structure.
[0047] In a preferred embodiment, the supporting beam 12 is made of rectangular tube, square tube or channel steel. In this embodiment, the supporting beam 12 is made of rectangular tube and is set between the two supporting vertical beams 11 by welding.
[0048] In some embodiments, the supporting vertical beam 11 can also be made of rectangular or square tubing to increase the rigidity of the composite screen structure.
[0049] In a preferred embodiment, the first support member 4 and the second support member 5 are both steel strips with a preset thickness, which are set between the two support beams 11 by means of screws or welding; under the premise of providing effective support for the corresponding screen, the steel strips are easy to obtain and can be easily connected to the two support beams 11.
[0050] In a preferred embodiment, the high-mesh screen 2 is detachably mounted on the upper surface of the support frame 1 via an upper pressure strip (not shown in the figure); the low-mesh screen 3 is detachably mounted on the lower surface of the support beam 12 via a lower pressure strip (not shown in the figure).
[0051] Example 2
[0052] This utility model also provides a vibrating screen, including a composite screen structure as described in Example 1. In use, materials with a preset particle size first pass through a high-mesh screen 2 (preferably a 32-mesh screen), and then fall onto a low-mesh screen 3 under the action of the swing screen power. At the same time, the ball-blocking ring 6 and the bouncing ball 7 collide with the high-mesh screen 2 and the low-mesh screen 3 from top to bottom and left to right, so that the material can be fully passed through the screen, ensuring the smooth operation of the vibrating screen. Since the composite screen structure adopts a two-layer composite screen, it has high rigidity and is not easily deformed during use, thus making the vibrating screen run smoothly. Compared with the traditional single-layer screen, it can greatly reduce the number of times the screen can be replaced, thereby improving production efficiency.
[0053] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
