Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of vibrating screen equipment technology, and more specifically, to a stacked vibrating screen having a common discharge port. Background Technology

[0002] A vibrating screen uses the reciprocating rotary vibration generated by the vibrator to make the material on the screen surface move up and down and forward. At the same time, the screen surface can be tilted at a certain angle to enhance the motion. Due to the difference in motion of materials of different particle sizes, stratification is generated, which in turn enhances the passage of fine particles and achieves particle size classification.

[0003] To improve screening efficiency, existing technologies employ vibrating screens with multiple layers of mesh. The screen box vibrates via an exciter, causing it to reciprocate. Material is thrown up and moves forward on the mesh. Because the aperture of the multiple mesh layers gradually decreases from top to bottom, particles smaller than the aperture of a certain layer pass through and fall to the next layer, achieving grading of materials of different sizes. However, in practical applications, situations arise where large quantities of material need to be screened in a short time, but space constraints prevent the placement of multiple screening devices. Some workshops stack vibrating screens, but this simple stacking doubles the number of connecting pipes between the screen's discharge pipe and the storage tank within the same vertical space. Therefore, simple stacking not only makes feeding material into the screening device inconvenient but also leads to complex discharge pipe layouts due to multiple material outlets. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a stacked vibrating screen with a common discharge port, which solves the technical problem of messy discharge pipes caused by stacking multiple vibrating screens due to space constraints in the prior art.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a stacked vibrating screen having a common discharge port, comprising:

[0006] support;

[0007] The first vibrating screen has two, which are arranged sequentially on the support along the height direction. Each first vibrating screen has a plurality of first discharge ports, which are used to discharge materials of different particle sizes.

[0008] The discharge component has two parts, which are arranged one-to-one at the discharge ends of the two first vibrating screens. Each discharge component has several independent second discharge ports, which correspond one-to-one with the first discharge ports. The discharge component has several guide plates inside, which are configured such that the material discharged from each first discharge port enters the corresponding second discharge port through the guide plate.

[0009] The second discharge ports of the discharge component described below are connected one-to-one with the second discharge ports of the discharge component described above through pipes.

[0010] For example, in a stacked vibrating screen with a common discharge port provided in at least one embodiment of this disclosure, the second discharge ports of the two discharge members are connected by a flexible pipe.

[0011] For example, in a stacked vibrating screen with a common discharge port provided in at least one embodiment of this disclosure, the first vibrating screen has a first feed port, and the support is further provided with a third feed member. The third feed member has a third feed port and two third discharge ports. The third discharge ports are located above the first vibrating screen, and the two third discharge ports are connected to the two first feed ports one-to-one through a pipe.

[0012] For example, in a stacked vibrating screen with a common discharge port provided in at least one embodiment of this disclosure, two material distribution plates are provided at the third discharge port. The ends of the two material distribution plates near the third inlet abut against each other. The two material distribution plates gradually move away from the third inlet. The two material distribution plates are aligned one-to-one with the channels communicating with the two first vibrating screens.

[0013] The two feed plates are used to guide the material entering through the third feed inlet to the first feed inlets of the two first vibrating screens, respectively.

[0014] For example, in a stacked vibrating screen with a common discharge port provided in at least one embodiment of this disclosure, the two material distribution plates are welded together at one end.

[0015] For example, in a stacked vibrating screen with a common discharge port provided in at least one embodiment of this disclosure, the two distribution plates are integrally bent into shape.

[0016] For example, in a stacked vibrating screen with a common discharge port provided in at least one embodiment of this disclosure, the discharge member is rotatably disposed with the first vibrating screen, and the first vibrating screen is configured such that, after the first vibrating screen rotates, the second discharge port is connected to or not connected to the first discharge port.

[0017] For example, in a stacked vibrating screen with a common discharge port provided in at least one embodiment of this disclosure, the end of the discharge member away from the rotation axis is bolted to the side wall of the first vibrating screen.

[0018] For example, in a stacked vibrating screen with a common discharge port provided in at least one embodiment of this disclosure, the support has a ladder located on one side of the third feeder.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] In this disclosure, by connecting the upper and lower discharge components, materials from the same screen layer of two identical first vibrating screens can be discharged from a single second discharge port, reducing the number of material outlet pipes, making the spatial layout more orderly, and avoiding environmental chaos caused by a large number of intertwined flexible pipes. Moreover, by setting up the discharge components, only the support frame needs to be modified to achieve the purpose of increasing the footprint of the original first vibrating screen.

[0030] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0032] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] like Figures 1-3As shown, this embodiment of the present disclosure illustrates a stacked vibrating screen with a common discharge port, comprising a support 100, two first vibrating screens 200, and a discharge component 300. The support 100 provides a stable support structure for the entire device. The two first vibrating screens 200 are sequentially mounted on the support 100 along their height direction, responsible for screening materials. Each of the two first vibrating screens 200 screens materials independently. This vertical arrangement improves screening efficiency without occupying excessive space, providing a solution for modifications that require increased production capacity but are space-constrained. The discharge components 300 are respectively located at the discharge ends of the two first vibrating screens 200, used to guide and integrate the material discharge path, solving the problem of complex feeding and discharging when multiple vibrating screens are stacked.

[0037] Each first vibrating screen 200 consists of a screen box, vibrator, and screen mesh. The screen box is welded from high-quality steel plates, possessing good strength and rigidity, capable of withstanding the vibrations generated by the vibrator without deformation. The vibrator is installed on both sides of the screen box, and is driven by a motor to rotate the eccentric blocks, generating reciprocating rotary vibration, causing the screen box to reciprocate. The screen mesh adopts a multi-layer design, generally 3-5 layers, with the mesh aperture gradually decreasing from top to bottom to achieve grading of materials of different particle sizes. The screen mesh is fixed inside the screen box by a tensioning device for easy replacement and adjustment. Each first vibrating screen 200 has several first discharge ports 210, the number of which is determined according to the number of screen mesh layers and actual screening requirements, generally 3-5. These first discharge ports 210 are located at the lowest end of the screen mesh, each first discharge port 210 corresponding to a different screen mesh layer, used to discharge materials of different particle sizes after screening. The first discharge port 210 is rectangular in shape. The end face of the rectangular first discharge port 210 is a flange face that can be connected to the discharge component 300. The size is designed according to the flow rate and particle size of the material to ensure that the material can be discharged smoothly.

[0038] The discharge component 300 is made of metal sheet (such as stainless steel), possessing good strength and corrosion resistance. The open end of the discharge component 300 is adapted to the discharge end of the vibrating screen. Material discharged from the first discharge port 210 can enter the discharge component 300. The discharge component 300 contains several guide plates 320, which divide the interior of the discharge component 300 into several independent channels. Each independent channel is connected to a first discharge port 210. These independent channels lead to different second discharge ports 310, from which material is discharged.

[0039] Several second discharge ports 310 of the lower discharge component 300 are connected one-to-one with several second discharge ports 310 of the upper discharge component 300 via pipes. These connecting pipes are made of flexible materials and are selected according to the actual installation space and material characteristics. Flexible pipes (such as rubber hoses) have a certain degree of flexibility, are easy to install and adjust, and can adapt to the different vibration frequencies of the two vibrating screens;

[0040] In situations where space is limited and multiple screening devices cannot be arranged, a double-layered first vibrating screen 200 effectively utilizes vertical space, enabling the screening of large quantities of material in a short time and meeting actual production needs. The design of the discharge component 300 and its guide plate 320 allows material to orderly enter the corresponding second discharge port 310 after exiting the first vibrating screen 200, and connects the upper and lower discharge components 300 through pipes, avoiding the problem of complex discharge pipe layout caused by simple stacking, making the discharge process simpler and more efficient.

[0041] For example, such as Figures 5-7 As shown, the third feeder 400 is made of metal (such as carbon steel or stainless steel), and its overall structure is robust and durable. It has one third feed inlet 410 and two third discharge outlets 420. The third feed inlet 410 is located at the top and is circular or rectangular in shape. Its size is adaptively adjusted according to the material feeding method and flow rate to ensure that the material can smoothly enter the third feeder 400. The two third discharge outlets 420 are located above the first vibrating screen 200 and are connected to the first feed inlets 220 of the two first vibrating screens 200 one-to-one via independent pipes. The third feeder 400 has an internal diversion structure, such as a guide plate or diversion cone, which can evenly distribute the incoming material to the two third discharge outlets 420, ensuring the uniformity of feeding between the upper and lower layers of the first vibrating screens 200.

[0042] The third feeder 400 solves the feeding problem of the double-layer vibrating screen, enabling simultaneous feeding of different first vibrating screens 200 and simplifying the feeding steps of multiple first vibrating screens 200. The use of the discharger 300, its guide plate 320, and the third feeder 400 allows one third feed port 410 to feed two first vibrating screens 200. After the material is discharged from the first vibrating screen 200, it can enter the corresponding second discharge port 310 in an orderly manner and be connected to the two dischargers 300 through a pipe. This allows the two stacked first vibrating screens 200 to reduce the channel connecting to the storage box by half, avoiding the inconvenience of feeding and the complex layout of the discharge pipe caused by simple stacking, making the feeding and discharging process simpler and more efficient.

[0043] For example, such as Figure 6As shown, two distribution plates 411 are provided at the third discharge port 420. The ends of the two distribution plates 411 near the third feed port 410 abut against each other to form a pointed tip, preventing material from accumulating above the two distribution plates 411. Moving away from the third feed port 410, the two distribution plates 411 gradually separate, unfolding in a V-shape. The two distribution plates 411 correspond one-to-one with the channels communicating with the two first vibrating screens 200, guiding the material entering from the third feed port 410 to the first feed ports 220 of the two first vibrating screens 200 respectively. The surface of the distribution plates 411 can be smoothed to reduce resistance to material flow and ensure smooth material distribution.

[0044] To ensure uniform feeding of the two first vibrating screens 200, the tips formed by the two distribution plates 411 and the centerline of the third feed inlet 410 can be located on the same vertical plane.

[0045] In some examples, the two material distribution plates 411 are welded together at one end, and the two material distribution plates 411 at the other end should be ground into an arc shape to avoid material accumulation at the tip of the two material distribution plates 411.

[0046] In some examples, two dividing plates 411 are integrally bent into shape, with the two dividing plates 411 being the two ends of the bend. The integral bending method not only simplifies the processing steps, but also automatically forms an arc tip at the bend, reducing the grinding steps compared to welding.

[0047] For example, such as Figure 1 , Figure 3 , Figure 4 As shown, the discharge component 300 is rotatably connected to the first vibrating screen 200. The first vibrating screen 200 is configured such that after the first vibrating screen 200 rotates, the second discharge port 310 is connected to or not connected to the first discharge port 210.

[0048] The discharge component 300 is rotatably connected to the first vibrating screen 200 via a rotating shaft and bearing housing. This allows the open end of the discharge component 300 to be either in contact with or not in contact with the discharge end of the first vibrating screen 200. When the open end of the discharge component 300 is in contact with the discharge end of the first vibrating screen 200, the material falling from the first discharge port 210 can enter the discharge component 300. When the open end of the discharge component 300 is not in contact with the discharge end of the first vibrating screen 200, the screen of the first vibrating screen 200 can be exposed, making it easier to deal with screen hole blockage or replace the screen.

[0049] For example, such as Figure 1 , Figure 3 As shown, the end of the discharge component 300 away from the rotation axis is bolted to the side wall of the first vibrating screen 200.

[0050] Bolted connections ensure that the discharge component 300 fits tightly against the discharge end of the first vibrating screen 200 during operation, preventing material leakage from the connection point. A flexible seal should also be added to the end of the discharge component 300 connected to the first vibrating screen 200, depending on the specific material, to further prevent leakage.

[0051] For example, such as Figure 1 As shown, the support 100 has a ladder 500, which is located on one side of the third feeder 400.

[0052] The ladder 500 extends from the ground to the same height as the third feeder 400. The height of the ladder 500 is designed according to actual operating requirements to facilitate the inspection and maintenance of the third feeder 400 and surrounding equipment components.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
