Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibrating composite screen. Background Technology

[0002] The current traditional screening process system in the industry is as follows: plate feeder → vibrating bar screen → magnetic separator → manual sorting platform → drum screen (2-3 stages) → air separator (2-3 stages). This system uses a plate feeder to feed materials evenly. The bar screen removes oversized materials (stones, wood), the magnetic separator removes scrap iron, and the manual sorting platform removes large, light materials that the bar screen cannot remove. Then, the multi-stage drum screen separates the materials into different sizes according to different apertures. Finally, the multi-stage air separator separates the light and small materials from the heavy materials according to different densities.

[0003] However, when using a vibrating screen to remove oversized materials (stones, wood), the fixed inclination angle of the bar screen causes the oversized materials to roll too fast when they are about to reach the external conveyor belt or storage area after being screened out, which can easily damage the external conveyor belt or pose a safety hazard. Therefore, a vibrating composite screen is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a vibrating composite screen.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] This utility model provides a vibrating composite screen, including a frame, on which a composite screen body and a drive assembly for driving the composite screen body to vibrate are provided; the composite screen body includes a frame and a bar screen disposed on the frame, the bar screen including a first screen plate group and a second screen plate group;

[0007] The first sieve plate group and the second sieve plate group are arranged alternately, and the included angle between the first sieve plate group and the second sieve plate group is 0-90 degrees.

[0008] Preferably, the frame is provided with an adjustment component, which is used to rotate the first screen plate group and / or the second screen plate group relative to the frame. By providing an adjustment component on the frame to drive the first screen plate group and / or the second screen plate group to rotate, the relative angle between the screen groups can be flexibly changed, thereby achieving the effect of dynamically optimizing the screening adaptability and efficiency according to the material characteristics.

[0009] Preferably, both the first and second sieve plate groups are composed of several independent sieve plate components. The adjustment assembly includes a first drive and a second drive. The first drive is used to drive the several sieve plate components included in the first sieve plate group to rotate, and the second drive is used to drive the several sieve plate components included in the second sieve plate group to rotate. By setting the first and second sieve plate groups to be composed of independent sieve plate components and configuring the first drive and the second drive to drive them respectively, the function of independent and precise angle control of the two sets of sieve plates is achieved. This realizes the effect of precise and independent adjustment of the sieve surface inclination angle of different sections in the composite screening area, so as to control the material behavior of each section in a targeted manner.

[0010] Preferably, the first screen plate group is located at the feed end of the frame, and the second screen plate group is located at the discharge end of the frame. The distance between the screen plate component near the feed end and the frame is not less than the distance between the screen plate component away from the feed end and the frame. By setting the first screen plate group at the feed end and the second screen plate group at the discharge end, and making the height of the screen plate component near the feed end from the frame not less than that of the screen plate component away from the feed end, the screen surface is arranged in a stepped or inclined manner in the direction of material flow. This achieves the effect of using gravity to assist material flow, preventing accumulation, and increasing the chance of material tumbling and passing through the screen through the drop.

[0011] Preferably, the machine frame is set on an external horizontal plane, and the screen plate component is set at an angle to the external horizontal plane, with the angle being 0-60 degrees. By setting the angle between the screen plate component and the horizontal plane to 0-60 degrees, an effective screening angle range is provided, which achieves the effect of providing the best screening projection intensity and residence time for materials with different physical properties while ensuring material flowability.

[0012] Preferably, the screen surfaces of the several screen plate components included in the first screen plate group are parallel, and the screen surfaces of the several screen plate components included in the second screen plate group are parallel. The screen surfaces of the screen plate components included in the first screen plate group and the screen surfaces of the screen plate components included in the second screen plate group are set at an angle of 0-60 degrees. By making the screen plates inside the first screen plate group parallel, the screen plates inside the second screen plate group parallel, and the two screen plate groups set at an angle of 0-60 degrees, a composite screening channel with a specific angle is formed on the screen surface, thereby achieving the effect of separately controlling the material flow rate.

[0013] Preferably, the screen plate component includes a support member and rod members arranged in an array on the support member. There is a gap between two adjacent rod members for material to fall. A connecting member is also provided between the rod member and the support member. The two ends of the support member are rotatably arranged relative to the frame in the length direction. By designing the screen plate component to include a support member, an array of rod members and a connecting member, and making the two ends of the support member rotatably arranged on the frame, a stable screen surface with a high opening ratio is formed and its inclination angle can be flexibly adjusted. This achieves the effect of providing efficient screening and convenient adjustment of the screen surface angle while ensuring the structural strength of the screen surface.

[0014] Preferably, the frame is provided with an elastic element, and the frame is inclined on the machine frame via the elastic element. The frame is provided with baffles at both ends in the length direction of the screen plate component. The baffles are used to reduce the direct impact damage of the material on the frame. By making the frame inclined on the machine frame via the elastic element and setting the baffles, the vibration impact is buffered, the noise is reduced, and the direct impact of the material on the end of the frame is reduced. This achieves the effects of improving the stability of equipment operation, reducing maintenance needs, and extending the service life of the equipment.

[0015] Preferably, a support plate is also provided at the end of the frame along its length. The support plate is used to reduce the direct impact damage of materials on the frame. By adding a support plate at the end of the frame, the end structure of the frame is further strengthened to resist the impact of materials, thereby achieving more effective dispersion of impact force, reducing the risk of frame deformation or damage, and improving the reliability of the equipment.

[0016] Preferably, the composite screen body is also equipped with a mesh screen, which is located at the bottom of the bar screen and the screen surface of the mesh screen is arranged at an angle to the horizontal plane. The mesh screen is used to further screen the undersize material after the bar screen. The materials screened by the mesh screen and the bar screen are respectively transported by conveyor belts to different downstream processing units for processing. By setting the mesh screen at the bottom of the bar screen, a secondary fine screening effect is achieved on the undersize material of the bar screen, realizing multi-level grading and separate collection of materials, and improving the purity and resource utilization value of the final product.

[0017] The beneficial effects of this utility model are:

[0018] By setting a drive component to drive the main body of the composite screen to vibrate, the material is thrown on the screen surface, achieving effective loosening, stratification and conveying of the material; by setting the bar screen to include a first screen plate group and a second screen plate group arranged in a cross-shaped manner with an angle between 0 and 90 degrees, the screen surface is formed to be non-parallel and has a specific angle, which can achieve the composite technical effect of enhancing material tumbling in a specific area, reducing material tumbling in a specific area and preventing screen hole clogging.

[0028] Reference Figures 1 to 5 A vibrating composite screen includes a frame 1, on which a composite screen body 2 and a drive assembly 3 for driving the composite screen body 2 to vibrate are provided; the composite screen body 2 includes a frame 21 and a bar screen 22 provided on the frame 21, the bar screen 22 including a first screen plate group 221 and a second screen plate group 222.

[0029] The first sieve plate group 221 and the second sieve plate group 222 are arranged crosswise, and the included angle between the first sieve plate group 221 and the second sieve plate group 222 is 0-90 degrees.

[0030] Specifically, in this embodiment, the included angle between the first sieve plate group 221 and the second sieve plate group 222 is 0-90 degrees, excluding 0 degrees and 90 degrees.

[0031] With the above-described structural configuration, during use, the composite screen body 2 is driven to vibrate by the drive component 3, thereby causing the material to generate a throwing motion on the screen surface, achieving effective loosening, stratification, and conveying of the material. By configuring the bar screen 22 to include a first screen plate group 221 and a second screen plate group 222 arranged in a cross-shaped manner with an angle between 0 and 90 degrees, the screen surface is formed to be non-parallel and has a specific angle, which can achieve the composite technical effect of enhancing material tumbling in a specific area, reducing material tumbling in a specific area, and preventing screen hole clogging.

[0032] Specifically, the frame 1 is also equipped with a foot area and steps. The steps are used by workers to reach the foot area from the base where the vibrating composite screen is placed. The foot area is used by workers to inspect or perform operations such as spreading out the material on the composite screen body 2.

[0033] Specifically, this technical solution only describes the improved parts, and other technologies known to those skilled in the art will not be elaborated. For example, how the drive component 3 realizes the vibration of the composite screen body 2 is known to those skilled in the art.

[0034] Specifically, the vibrating composite screen also includes a central control mechanism, which is used to control and coordinate the various components.

[0035] Specifically, the frame 21 is provided with an adjustment component 4. The adjustment component 4 is used to rotate the first screen plate group 221 and / or the second screen plate group 222 relative to the frame 21. By providing the adjustment component 4 on the frame 21 to drive the first screen plate group 221 and / or the second screen plate group 222 to rotate, the relative angle between the screen plate groups can be flexibly changed, thereby achieving the effect of dynamically optimizing the screening adaptability and efficiency according to the material characteristics.

[0036] Specifically, the first sieve plate group 221 and the second sieve plate group 222 are both composed of several independent sieve plate components 220.

[0037] Specifically, the adjustment component 4 can also be a hinge and pin positioning mechanism: the screen plate components 220 of the first screen plate group 221 and the second screen plate group 222 are mounted on the frame 21. The adjustment component 4 is a set of positioning holes on the screen plate components 220 and a corresponding pin. The pin is slidably mounted on the frame 1. The pin is inclined relative to the frame 1 to prevent it from falling off the positioning holes on the screen plate components 220 due to vibration or gravity. By pulling out the pin, adjusting the screen plate components 220 to the required angle, and then inserting the pin to fix it, a low-cost and reliable angle adjustment and locking function is achieved.

[0038] Specifically, the adjustment component 4 includes a first drive member 41 and a second drive member 42. The first drive member 41 is used to drive the rotation of several screen plate components 220 included in the first screen plate group 221, and the second drive member 42 is used to drive the rotation of several screen plate components 220 included in the second screen plate group 222. By setting the first screen plate group 221 and the second screen plate group 222 to be composed of independent screen plate components 220, and configuring the first drive member 41 and the second drive member 42 to drive them respectively, the function of independent and precise angle control of the two sets of screen plates is generated, realizing the precise and independent adjustment of the screen surface inclination angle of different sections in the composite screening area, so as to control the material behavior of each section in a targeted manner.

[0039] Specifically, the first screen plate group 221 is located at the feed end of the frame 21, and the second screen plate group 222 is located at the discharge end of the frame 21. The distance between the screen plate component 220 near the feed end and the frame 1 is not less than the distance between the screen plate component 220 away from the feed end and the frame 1. By setting the first screen plate group 221 at the feed end and the second screen plate group 222 at the discharge end, and making the height of the screen plate component 220 near the feed end from the frame 1 not less than the height of the screen plate component 220 away from the feed end, the screen surface is arranged in a stepped or inclined manner in the direction of material flow. This achieves the effect of using gravity to assist material flow, preventing accumulation, and increasing the chance of material tumbling and passing through the screen through the drop.

[0040] Specifically, the frame 1 is set on the external horizontal plane, and the screen plate component 220 is set at an angle with the external horizontal plane, with the angle being 0-60 degrees. By setting the angle between the screen plate component 220 and the horizontal plane to 0-60 degrees, an effective screening angle range is provided, which achieves the effect of providing the best screening projection intensity and residence time for materials with different physical properties while ensuring material flowability.

[0041] Specifically, the screen surfaces of the several screen plate components 220 included in the first screen plate group 221 are parallel, and the screen surfaces of the several screen plate components 220 included in the second screen plate group 222 are parallel. The screen surfaces of the screen plate components 220 included in the first screen plate group 221 and the screen surfaces of the screen plate components 220 included in the second screen plate group 222 are set at an angle of 0-60 degrees. By making the screen plates inside the first screen plate group 221 parallel and the screen plates inside the second screen plate group 222 parallel, and setting the two screen plate groups at an angle of 0-60 degrees, a composite screening channel with a specific angle is formed on the screen surface, thereby achieving the effect of separately controlling the material flow rate.

[0042] Specifically, the screen plate component 220 includes a support member 2201 and rod members 2202 arrayed on the support member 2201. There is a gap between two adjacent rod members 2202 for material to fall. A connecting member 2203 is also provided between the rod members 2202 and the support member 2201. The two ends of the support member 2201 in the length direction are rotatably set relative to the frame 1. By designing the screen plate component 220 to include the support member 2201, the arrayed rod members 2202 and the connecting member 2203, and making the two ends of the support member 2201 rotatably set on the frame 1, a stable screen surface with a high opening ratio is formed and its inclination angle can be flexibly adjusted. This achieves the effect of providing efficient screening and convenient adjustment of the screen surface angle while ensuring the structural strength of the screen surface.

[0043] Specifically, the rod member 2202 is screwed or welded to the support member 2201, and the connector 2203 is used to enhance the mechanical strength between the rod member 2202 and the support member 2201.

[0044] Specifically, the vibrating composite screen also includes a material detection component 5, which includes a dry and wet detection module. The dry and wet detection module is used to detect the dry and wet state of the material. When the material is relatively dry, the angle between the screen surface of the screen plate component 220 and the horizontal plane should be smaller than the angle between the screen surface of the screen plate component 220 and the horizontal plane when the material is relatively wet.

[0045] The vibrating composite screen also includes a material detection component 5, which includes a density detection module. The density detection module is used to detect the density of the material. When the material is heavier, the angle between the screen surface of the screen plate component 220 and the horizontal plane should be smaller than the angle between the screen surface of the screen plate component 220 and the horizontal plane when the material is lighter.

[0046] Specifically, the adjustment component 4 also includes a gear 44 disposed on the support member 2201 and a toothed plate 43 slidably disposed on the frame 21. The toothed plate 43 is meshed with the gear 44. The first driving member 41 and the second driving member 42 are respectively used for the corresponding toothed plate 43 to slide relative to the frame 21. The first driving member 41 and the second driving member 42 can be screws that are rotatably disposed on the frame 21 and screwed to the toothed plate 43.

[0047] Specifically, the frame 21 is provided with an elastic element 11, and the frame 21 is inclinedly mounted on the frame 1 via the elastic element 11. The frame 21 is provided with baffles 211 at both ends along the length of the screen plate component 220. The baffles 211 are used to reduce the direct impact damage of materials on the frame 21. By making the frame 21 inclinedly mounted on the frame 1 via the elastic element 11 and providing baffles 211, the vibration impact is buffered, the noise is reduced, and the direct impact of materials on the ends of the frame 21 is reduced, thereby improving the stability of equipment operation, reducing maintenance needs, and extending the service life of the equipment.

[0048] Specifically, a support plate 212 is provided at the end of the frame 21 along its length. The support plate 212 is used to reduce the direct impact damage of materials on the frame 21. By adding a support plate 212 at the end of the frame 21, the end structure of the frame 21 is further strengthened to resist the impact of materials, thereby achieving more effective dispersion of impact force, reducing the risk of deformation or damage to the frame 21, and improving the reliability of the equipment.

[0049] Specifically, the composite screen body 2 is also equipped with a mesh screen 23. The mesh screen 23 is located at the bottom of the bar screen 22 and the screen surface of the mesh screen 23 is arranged crosswise with the horizontal plane. The mesh screen 23 is used to further screen the undersize material after the bar screen 22. The materials screened by the mesh screen 23 and the bar screen 22 are respectively transported to different downstream processing units by external conveyor belts. By setting the mesh screen 23 at the bottom of the bar screen 22, a secondary fine screening effect is achieved on the undersize material of the bar screen 22, realizing multi-level grading and separate collection of materials, and improving the purity and resource utilization value of the final product.

[0050] Specifically, the vibrating composite screen also includes a conveying mechanism 6, which is located at the bottom of the composite screen body 2. The conveying mechanism 6 is used to convey the undersize material after the screen 23. The conveying direction of the conveying mechanism 6 is opposite to the conveying direction of the screen 23 and / or the bar screen 22.
