Description

Technical Field

[0001] The utility model provides an efficient vibrating powder sieve, belonging to the technical field of vibrating screening machines. Background Art

[0002] A vibrating screening machine is a device that screens materials through vibration or rotational motion. It classifies materials according to particle size through sieve holes of different specifications, thereby realizing the separation and classification of materials. The screening machine usually consists of a frame, a sieve box, a vibrating motor, a sieve mesh, etc., and has the ability to screen quickly and continuously. It is widely used in industries such as mining, building materials, chemical engineering, metallurgy, and food processing. It can quickly screen and classify materials, improve production efficiency and product quality. Different types of screening machines can be selected according to different needs.

[0003] Existing vibrating screening machines can basically meet the usage requirements. However, when screening powdery materials, due to the relatively small particle diameter of powdery materials, there may be a situation where some powdery materials stick together when added to the screening machine. And the powdery materials added to the screening machine do not spread and move quickly to the periphery like large granular materials when vibrating. Instead, they often pile up together first and then slowly spread to the periphery when vibrating later, which inevitably affects the screening efficiency of powdery materials. Based on this, the utility model provides an efficient vibrating powder sieve. Summary of the Utility Model

[0004] The technical problem solved by the utility model is that when powdery materials are added to the screening machine, there may be a situation where they stick together and are prone to piling up, which inevitably affects the screening efficiency of powdery materials.

[0005] To solve the technical problem, the technical solution provided by the utility model is: an efficient vibrating powder sieve, including an elastic base assembly, and a powder sieve box arranged on the top of the elastic base assembly. A plurality of inclined sieve meshes are arranged in the powder sieve box. A powder scattering assembly is arranged on the inner upper wall of the powder sieve box. The powder scattering assembly includes chutes symmetrically arranged on the two inner upper walls of the powder sieve box. Sliders are slidably connected in the chutes. A connecting plate is arranged between the sliders. A plurality of powder scattering rods are arranged at equal intervals at the bottom of the connecting plate and above the uppermost sieve mesh. A spring is fixedly connected between one inner side wall of the chute and the side wall of the slider.

[0006] Further, a feed hopper is arranged at the center of the top of the powder sieve box, and a baffle is rotatably connected to one side of the top of the feed hopper.

[0007] Further, an inclined material sliding table is arranged at the bottom of the inner part of the powder sieve box, and a discharge port is arranged on one side wall of the powder sieve box at the top of the lower end of the slope of the sieve mesh and the material sliding table.

[0008] Furthermore, a vibration motor is provided at the bottom of the powder screening box.

[0009] Furthermore, the screen apertures of the multiple screens decrease sequentially from top to bottom. The inclination angle of the screens is 5° - 30°, and the height difference between the top wall of the uppermost screen and the bottom end of the powder scattering rod is 5 - 12 mm.

[0010] Furthermore, a limiting rail matching the side wall of the slider is provided on the inner side wall of the sliding groove.

[0011] Advantages of the present utility model:

[0012] Through the powder scattering assembly, when the powder screening box vibrates continuously, the sliding groove is driven to vibrate. Under the action of the spring, the slider can move back and forth irregularly in the sliding groove, thereby driving the connecting plate and the powder scattering rod to move back and forth irregularly, which can break up the powdery materials stuck together and accelerate the pushing and spreading of the piled-up powdery materials to the surrounding areas, making full use of each position of the screen and effectively improving the screening effect of the powder.

[0018] The present utility model will be further described below with reference to the drawings.

[0019] According to the attached Figure 1 、 2As shown in the figure: The utility model provides an efficient vibrating sieve powder machine, which includes an elastic base assembly 1 and a powder screening box 2 arranged on the top of the elastic base assembly 1. A vibrating motor 14 is arranged at the bottom of the powder screening box 2 to play a vibrating role. A feed hopper 10 is arranged at the center of the top of the powder screening box 2. One side of the top of the feed hopper 10 is rotatably connected with a baffle 11 to cover the feed hopper 10 to prevent the powdery material to be screened inside from floating out of the feed hopper 10. A plurality of inclined screens 3 are arranged in the powder screening box 2. A sliding material table 12 is arranged obliquely at the bottom of the powder screening box 2. A discharge port 13 is arranged on one side wall of the powder screening box 2 at the top of the lower inclined ends of the screens 3 and the sliding material table 12. The screen apertures of the plurality of screens 3 decrease sequentially from top to bottom. The inclination angle of the screen 3 is 5°-30°, which plays a role in conveniently discharging the powdery material staying on the top of the screen 3 from the discharge port 13, and can screen out powdery materials with various specification diameters. When the vibrating motor 14 is started, the powder screening box 2 vibrates under the action of the elastic base assembly 1, and then the screen 3 vibrates to prevent the powdery material from blocking the screen holes. The principle of vibration is the existing structure of the existing vibrating screening machine, and will not be elaborated here too much.

[0020] According to the attached Figure 2 、 3 、4 as shown in the figure: A powder scattering assembly 4 is arranged on the inner upper wall of the powder screening box 2. The powder scattering assembly 4 includes sliding grooves 5 symmetrically arranged on the two inner upper walls of the powder screening box 2. A slider 6 is slidably connected in the sliding groove 5. A limiting rail 15 matching the side wall of the slider 6 is arranged on the inner side wall of the sliding groove 5 to play a role in limiting the slider 6. A connecting plate 7 is arranged between the sliders 6. A plurality of powder scattering rods 8 are arranged at equal intervals at the bottom of the connecting plate 7 above the uppermost screen 3. A spring 9 is fixedly connected between one inner side wall of the sliding groove 5 and the side wall of the slider 6. The height difference between the top wall of the uppermost screen 3 and the bottom end of the powder scattering rod 8 is 5-12 mm. When the powder screening box 2 vibrates continuously, the sliding groove 5 is driven to vibrate. Since the slider 6 can move in the sliding groove 5 and considering the different vibration conditions at different times, the slider 6 moves back and forth irregularly in the sliding groove 5. By setting the spring 9, on the one hand, it buffers the irregular movement of the slider 6, and on the other hand, after buffering, the spring 9 rebounds and resets. The spring 9 can continuously stretch and contract, so that the slider 6 can continuously move back and forth irregularly in the sliding groove 5, thereby driving the connecting plate 7 and the powder scattering rods 8 to continuously move back and forth irregularly, so as to break up the powdery material that adheres together. And because the powdery material added from the feed hopper 10 into the powder screening box 2 accumulates together, through the continuous back-and-forth movement of the powder scattering rods 8, the accumulated powdery material can be pushed and diffused to the surrounding area more quickly, making full use of each position of the screen 3 and effectively improving the screening effect of the powder.

[0021] The principle of the present utility model

[0022] During use, powdered materials are added to the powder screening box 2 from the feed hopper 10. The vibration motor 14 is started, and under the action of the elastic base assembly 1, the powder screening box 2 vibrates, and then the screen 3 vibrates, avoiding the clogging of the powder screening holes by the powdered materials. When the powder screening box 2 continuously vibrates, it drives the chute 5 to vibrate. Under the action of the spring 9, the slider 6 can continuously move back and forth irregularly in the chute 5, thereby driving the connecting plate 7 and the powder scattering rod 8 to continuously move back and forth irregularly. As a result, the powdered materials bonded together can be scattered, and the piled-up powdered materials can be quickly pushed and diffused towards the periphery, making full use of each position of the screen 3 and effectively improving the screening effect of the powder materials.

[0023] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
