TECHNICAL FIELD

[0001] The utility model relates to the technical field of screening machines, especially to a screening machine for industrial solid waste auxiliary materials. BACKGROUND

[0002] The rotary screening machine is a kind of high-efficiency screening and grading equipment, and its core working principle is to drive the screen body to continuously rotate by a motor. In this process, the material is uniformly fed onto the screen, and is constantly subjected to vibration and throwing action with the rotation of the screen body, so as to realize the classification and screening of particles. The screening machine is usually designed with multiple layers of screen, and particles of different sizes are separated to different levels according to the size of the screen aperture, which has the advantages of high screening efficiency, large processing capacity, adjustable screening precision, stable and reliable operation, etc., and is one of the indispensable important equipment in modern industrial production.

[0003] However, when the rotary screening machine in the prior art faces materials with smaller particle size, the screening efficiency will be reduced due to the caking of the materials, especially when the caked materials are agglomerated at the bottom of the screen, since the caked materials are heavier, it is difficult to be thrown up with the rotation of the screen, and finally it is screened out together with larger particles and impurities. At the same time, in order to increase the height of the material being thrown up, it is often only possible to achieve this by speeding up the rotation of the screen, but speeding up the rotation of the screen is not conducive to the screening of the material.

[0007] Further, in order to separate the material after being completely screened by the screen plate, the material selection port is arranged on one side close to the discharge port.

[0008] Further, in order to make the dust raising plate located at the bottom of the screen plate not block the movement of the material in the axial direction of the screen plate, the extension direction of the dust raising plate is consistent with the axial direction of the shell, and the dust raising plate is welded on the inner wall of the screen plate.

[0028] The drawings will be described in detail below. Figures 1-2 The embodiments of the technical solutions of the present application will be described in detail. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0029] Embodiment One:

[0030] Please refer to Figure 1 and Figure 2 In this embodiment, in order to increase the throwing height of the material and improve the screening efficiency, the screening machine for industrial solid waste auxiliary materials of the present application is provided with a spiral conveying plate 77 on the inner wall of the screen plate 74. This design enables the material to travel a longer distance along the conveying plate 77 during the screening process, increasing the contact time and screening opportunities of the material with the screen plate 74. At the same time, the inside of the screen plate 74 is also provided with a dust lifting plate 78, which extends in the same direction as the axis of the shell 75 and is welded on the inner wall of the screen plate 74. When the material moves on the conveying plate 77, it will be gathered and lifted to a higher position by the dust lifting plate 78, and then thrown up, thereby increasing the throwing height of the material. This design effectively solves the problem of material agglomeration being difficult to screen in the prior art, and improves the screening efficiency.

[0031] Optionally, the conveying plate 77 can be arranged in an intermittent manner, or the conveying plate 77 can be arranged in an integrated spiral conveying manner. The conveying plate 77 can be further increased in movement distance inside the screening machine by changing from an intermittent arrangement to an integrated continuous arrangement.

[0032] Embodiment Two:

[0033] Please refer to Figure 1 and Figure 2 In this embodiment, in order to enhance the airflow effect during the screening process, i.e. to further improve the screening efficiency, the present application is provided with a jet device 710 on one side of the shell 75 along the axial direction thereof, and the jet nozzle of the jet device faces the inside of the shell 75. When the material is lifted and thrown up by the dust lifting plate 78, the airflow generated by the jet device 710 can carry the material, making it better dispersed and separated. This design not only enhances the airflow effect during the screening process, but also helps the separation of coarse and fine materials during the throwing process, further improving the screening effect.

[0034] Embodiment Three:

[0035] Please refer to Figure 1 and Figure 2In this embodiment, in order to adjust the inclination angle of the screen plate and change the material residence time, the screening machine of the present application is also provided with a telescopic device 4 connected to one side of the base 1 through the fixing plate 3, and the output end thereof is connected to the second mounting bracket 22 through the fixing plate 3. The first mounting bracket 21 is directly connected to the base 1 through a pin column. This design enables the telescopic device 4 to drive the outer shell 75 and the screen plate 74 to change the angle, thereby adjusting the inclination angle of the screen plate 74 with the ground. By adjusting the telescopic amount of the telescopic device 4, the residence time of the material in the screen plate 75 can be changed, and the screening effect can be adjusted as needed. This adjustment method is flexible and convenient, and has strong adaptability, which can meet the needs of different materials and different screening requirements.

[0036] Embodiment Four

[0037] Please refer to Figure 1 and Figure 2 In this embodiment, in order to optimize the design of the impact column and improve the material crushing effect, in order to better crush the material in the form of clumps, the present application is provided with a plurality of impact columns 79 along the radial direction of the outer shell 75 at one end of the screen plate 74 close to the feed inlet 71. These impact columns 79 are tightly attached to the inner wall of the screen plate 74 and are fixed by bolts penetrating through the screen plate 74. When the material enters the screening machine, it will first collide with the impact columns 79, thereby being crushed into smaller particles. This design not only improves the material crushing effect, but also helps to reduce the accumulation and clumping of the material at the bottom of the screen plate 74, further improving the screening efficiency. At the same time, the impact columns 79 are fixed by bolts, which is convenient for replacement and maintenance after wear.
