Abstract
Description
Technical Field
[0001] The utility model relates to a three-stage screening machine, which is applicable to the technical field of screening machine equipment. Background Art
[0002] Screening machines utilize the relative motion between bulk material and the screen surface, allowing some particles to pass through the mesh, thereby separating the material into different grades based on particle size. The screening process is generally continuous: material smaller than the mesh size passes through the mesh, becoming the undersize product; material larger than the mesh size is continuously discharged from the screen surface, becoming the oversize product. Current screening machines often utilize a single mesh screen. Further screening requires placing the material on meshes of different mesh sizes, significantly increasing operating time. Furthermore, the screening process can easily generate dust, impacting the surrounding environment. Utility Model Content

In this way, after the material is put into the device body through the feed port, it is screened by the first sieve plate and the second sieve plate, and the material installation diameter is divided into three parts, and is discharged from the first discharge port, the second discharge port, and the third discharge port in descending order of diameter. The first discharge port and the second discharge port are arranged at the front of the device body, and the third discharge port is arranged at the rear of the device body, which can effectively avoid the mixing of materials falling from different discharge ports.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0014] This embodiment is a three-stage screening machine having a device body 1.
[0015] In this embodiment, a feed port 2 is formed at the top position of the device main body 1 at the rear position of the device main body 1, a first sieve plate 6 is arranged in the device main body 1 below the feed port 2, and a second sieve plate 12 is arranged below the first sieve plate 6. The first sieve plate 6 and the second sieve plate 12 are both arranged obliquely from the rear of the device main body 1 to the front of the device main body 1, and a discharge plate 13 is arranged below the second sieve plate 12. The discharge plate 13 is arranged obliquely from the front of the device main body 1 to the rear of the device main body 1, a first discharge port 3 is formed at the front of the device main body 1 at a position corresponding to the first sieve plate 6, a second discharge port 4 is formed at the front of the device main body 1 at a position corresponding to the second sieve plate 12, and a third discharge port 5 is formed at the rear of the device main body 1 at a position corresponding to the discharge plate 13. In this way, after the material is put into the device body 1 from the feed port 2, it is screened by the first sieve plate 6. The material with a diameter larger than the mesh diameter of the first sieve plate 6 is discharged through the first discharge port 3, and the material with a diameter smaller than the mesh diameter of the first sieve plate 6 passes through the first sieve plate 6; these materials fall onto the second sieve plate 12. At this time, the material with a diameter larger than the mesh diameter of the second sieve plate 12 is discharged through the second discharge port 4, and the material with a diameter smaller than the mesh diameter of the second sieve plate 12 passes through the second sieve plate 12 and falls onto the discharge plate 13, and falls out from the third discharge port 5. In this way, three-level screening of the material is achieved, and the screening efficiency of the screening machine is improved. The material screened by the second sieve plate 12 has a smaller diameter and is prone to mixing. However, because the third discharge port 5 is arranged at the rear of the device body 1 and the second discharge port 4 is arranged at the front of the device body 1, it is not easy for the material to mix after screening.
[0016] In this embodiment, a conveying mechanism is provided between the first sieve plate 6 and the second sieve plate 12 in the device body 1, wherein a driving wheel and a driven wheel are provided in the device body 1, and a conveyor belt 11 is connected between the driving wheel and the driven wheel. The conveyor belt 11 is arranged in a direction parallel to the second sieve plate 12. A drive motor 7 is installed on the device body 1, and the driving wheel is connected to the output shaft of the drive motor 7. In this way, when the drive motor 7 is running, it can drive the conveyor belt 11 to move between the driving wheel and the driven wheel, thereby transporting the material falling from the first sieve plate 6 to the end position of the second sieve plate 12 near the rear of the device body 1, so that the material can be completely screened by the second sieve plate 12.
[0017] In this embodiment, a dust reduction module is provided on the device body 1. A water tank 8 is installed on the device body 1, and nozzles 15 are provided at the first, second, and third discharge ports 3, 4, and 5. The nozzles 15 are connected to the water tank 8 via a water pipe 10, which is provided with a water pump 9. A booster 14 is provided at the nozzles 15. Thus, when the screening machine is in operation, a large amount of dust is generated. This dust is discharged outside the device body 1 through the first, second, and third discharge ports 3, 4, and 5, thereby affecting the surrounding environment. In this embodiment, the water in the water tank 8 is pumped by the water pump 9 to the nozzles 15 at the first, second, and third discharge ports 3, 4, and 5, and then sprayed by the nozzles 15 at the first, second, and third discharge ports 3, 4, and 5, thereby adsorbing the dust at the first, second, and third discharge ports 3, 4, and 5, thereby achieving an effective dust reduction effect.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
