Abstract
Description
Technical Field
[0001] This utility model relates to the field of material sorting technology, and in particular to a vortex vibrating screen. Background Technology
[0002] Non-metallic minerals need to be screened after being ground and crushed.
[0003] A search revealed a prior art vortex vibrating screen (publication number: CN221714581U), comprising a vibrating screen body and a secondary screening mechanism. The vibrating screen body includes a first hopper, a second hopper, and a vibrating chamber. The bottom wall of the first hopper is fixedly connected to the top wall of the vibrating chamber. Multiple second hoppers are coaxially stacked above the first hopper. A screen assembly is engaged between the first hopper and the second hopper or between two adjacent second hoppers, and the first hopper and the second hopper or two adjacent second hoppers are fixedly and detachably connected. Both the first hopper and the second hopper have discharge ports on their side walls, and the discharge ports are connected to a discharge pipe. The secondary screening mechanism is fixedly connected to the discharge pipe.
[0004] Existing technology optimizes the filter screen and uses multiple discontinuous spiral screens to sort materials. However, the materials can only be sorted according to the flow trajectory of the screen. That is, the materials first flow and are sorted along the upper spiral screen before being sent to the next screen for sorting. The continuous screening effect is not good, which limits the production efficiency and has room for optimization.
[0005] Therefore, we propose a vortex vibrating screen. Utility Model Content
[0006] The present invention mainly addresses the technical problem of poor continuous screening effect mentioned above by providing a vortex vibrating screen.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a vortex vibrating screen, comprising:
[0008] A base, on the top of which several elastic telescopic rods are fixedly installed, and a sorting cylinder is fixedly installed on the output shaft of the elastic telescopic rods, and a vibration motor is fixedly installed on the bottom of the sorting cylinder;
[0009] A sieve plate structure is installed inside the sorting cylinder cavity for sorting materials. The sieve plate structure includes a sieve plate body and ribs. Several sets of sieve plate structures are provided inside the sorting cylinder cavity. Each set of sieve plate structures includes two symmetrically distributed sieve plate bodies. Several ribs are fixedly installed on the top of each sieve plate body. The sieve plate body is uniformly provided with sieve holes.
[0010] In a preferred embodiment of this utility model, the screen plate body is spiral-shaped, the two screen plate bodies in the same group have opposite spiral directions, the two ends of the two screen plate bodies are fixedly connected to each other, and a feed hopper is fixedly installed on the top of the base.
[0011] In a preferred embodiment of this utility model, the rib is an arc-shaped rod, which is fixedly installed on the spiral surface of the sieve plate body. The rib extends from the outer circumference of the sieve plate body to the inner circumference, and multiple ribs are radially distributed on the sieve plate body.
[0012] In a preferred embodiment of this utility model, the sieve plate structure further includes a slag discharge port, and the sieve plate body has a slag discharge port for material discharge.
[0013] In a preferred embodiment of this utility model, the screen plate structure further includes a slag discharge trough, and the sorting cylinder is fixedly installed with several slag discharge troughs, which can discharge the material sorted by the screen plate body.
[0014] In a preferred embodiment of this utility model, the slag discharge trough is located directly below the slag discharge port, and the two screen plate bodies have a common slag discharge port at their ends, which can discharge materials into the slag discharge trough.
[0015] In a preferred embodiment of this utility model, the bottom of the base is provided with a window for discharging material, and a material discharge pipe is fixedly installed at the window.
[0016] This utility model provides a vortex vibrating screen. It has the following beneficial effects:
[0017] 1. This vortex vibrating screen simultaneously sorts materials discharged from the feed inlet using two symmetrically distributed screen plates. One end of the screen plate is higher than the other, and the hopper is directly opposite the higher end of the two screen plates. The material flows along the spiral screen plate to form a vortex. Combined with the vibration motor, the entire sorting cylinder generates amplitude, enabling rapid and efficient material sorting. Multiple ribs further divert the material, ensuring uniform dispersion on the screen plate. Material larger than the screen aperture flows along the spiral surface of the screen plate, while material smaller than the screen aperture falls to another set of screen plates below for further screening, achieving continuous multi-stage screening. While ensuring screening effect, this solution improves screening efficiency and suppresses material blockage. Compared with existing technologies that use multiple discontinuous screen plates for sorting, this solution provides better continuous screening effect.
[0018] 2. This vortex vibrating screen, by opening a slag discharge trough at a lower position on the screen plate body, allows materials larger than the screen hole diameter to fall from the slag discharge port onto the slag discharge trough when they roll down to the lower part of the spiral surface of the screen plate body. The materials are then discharged out of the sorting cylinder through the inclined slag discharge trough, thus achieving material sorting. It has a simple structure, good material flowability, and is not prone to clogging. Attached Figure Description

[0025] A vortex vibrating screen, such as Figure 1 and Figure 2 As shown, it includes:
[0026] The base 10 has several elastic telescopic rods 11 fixedly installed on its top. The output shaft of the elastic telescopic rods 11 is fixedly installed with a sorting cylinder 12. The bottom of the sorting cylinder 12 is fixedly installed with a vibration motor. The vibration motor needs to be connected to a control switch and a power supply. The bottom of the base 10 has a window for discharging material. A discharge pipe is fixedly installed at the window. The discharge pipe is used to discharge the screened material.
[0027] like Figure 3 , Figure 4 and Figure 5 As shown, a screen plate structure is set in the cavity of the sorting cylinder 12 for sorting materials. The screen plate structure includes a screen plate body 20 and ribs 21. Several sets of screen plate structures are provided in the cavity of the sorting cylinder 12. Each set of screen plate structures includes two symmetrically distributed screen plate bodies 20. Several ribs 21 are fixedly installed on the top of each screen plate body 20. The screen plate body 20 is evenly provided with screen holes. The screen plate body 20 is spiral. The spiral directions of the two screen plate bodies 20 in the same set are opposite. The two ends of the two screen plate bodies 20 are fixedly connected to each other. A feed hopper is fixedly installed on the top of the base 10. The ribs 21 are arc-shaped rods. The ribs 21 are fixedly installed on the spiral surface of the screen plate body 20. The ribs 21 extend from the outer circumference of the screen plate body 20 to the inner circumference. Multiple ribs 21 are radially distributed on the screen plate body 20.
[0028] In this scheme, materials discharged from the feed inlet are simultaneously sorted by two symmetrically distributed screen plate bodies 20. One end of the screen plate body 20 is higher and the other end is lower. The hopper is directly opposite the higher end of the two screen plate bodies 20. The material flows along the spiral screen plate body 20 to form a vortex. With the help of the vibrating motor, the sorting cylinder 12 generates an amplitude, which can quickly and efficiently sort materials. With the help of multiple ribs 21 to divert the material, the material is evenly dispersed on the screen plate body 20. The material larger than the screen hole flows along the spiral surface of the screen plate body 20, and the material smaller than the screen hole falls to another set of screen plate structures below for further screening, realizing continuous multi-stage screening. While ensuring the screening effect, the screening efficiency is improved and the material blockage is suppressed. Compared with the existing technology that uses multiple discontinuous screen plate bodies 20 for sorting, the continuous screening effect of this scheme is better.
[0029] like Figure 4 As shown, the screen plate structure also includes a slag discharge port 22. The screen plate body 20 is provided with a slag discharge port 22 for material discharge. The screen plate structure also includes a slag discharge trough 23. Several slag discharge troughs 23 are fixedly installed on the sorting cylinder 12. The slag discharge trough 23 can discharge the material sorted by the screen plate body 20. The slag discharge trough 23 is located directly below the slag discharge port 22. The two screen plate bodies 20 are provided with a slag discharge port 22 at their ends. The slag discharge port 22 can discharge the material into the slag discharge trough 23.
[0030] By opening a slag discharge trough 23 at a lower position on the screen plate body 20, materials larger than the screen hole diameter roll down to the lower part of the spiral surface of the screen plate body 20 and fall from the slag discharge port 22 onto the slag discharge trough 23. After passing through the inclined slag discharge trough 23, the materials are discharged outside the sorting cylinder 12, thus achieving material sorting. The structure is simple, the material has good flowability, and it is not easy to clog.
[0031] The working principle of this utility model is as follows: The material discharged from the feed inlet is simultaneously sorted by two symmetrically distributed screen plate bodies 20. One end of the screen plate body 20 is higher and the other end is lower. The hopper is directly opposite the higher end of the two screen plate bodies 20. The material flows along the spiral screen plate body 20 to form a vortex. With the help of the vibrating motor, the sorting cylinder 12 as a whole generates an amplitude, which can quickly and efficiently sort the material. With the help of multiple ribs 21 to divert the material, the material is evenly dispersed on the screen plate body 20. The material larger than the screen hole flows along the spiral surface of the screen plate body 20, and the material smaller than the screen hole falls to another set of screen plate structures below for further screening, realizing continuous multi-stage screening. When the material larger than the screen hole diameter rolls to the lower part of the spiral surface of the screen plate body 20, it falls from the slag discharge port 22 onto the slag discharge trough 23 and is discharged from the sorting cylinder 12 through the inclined slag discharge trough 23.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
