Description

Technical Field

[0001] This utility model relates to the field of powder screening technology, specifically to a powder vibrating screen. Background Technology

[0002] Material refers to fine solid powder obtained through processes such as crushing, grinding, and sieving. It has a wide range of applications, and vibrating screens are often used for screening during the material separation and sieving process.

[0003] A search revealed that the announcement number is CN218872824U, and the name is "A Powder Vibrating Screen," which includes an outer frame. Research and analysis showed that although this device prevents powder from falling off the top of the screen through the edge of the screen, and when screening powder, lumps and other impurities are intercepted at the top of the screen, by unlocking one end of the screen and flipping the side baffle, the screen can be flipped along the mounting plate and tilted, thus facilitating the cleaning of lumps and other impurities at the top of the screen, it still has the following drawbacks to some extent.

[0004] For example, when the device is screening and distributing materials, the materials tend to accumulate, which makes it impossible to screen the accumulated materials quickly. This requires the vibrating screen to work for a long time, reducing the screening efficiency. At the same time, dust will be raised during the vibrating screening process, which will pollute the environment. In order to solve the above technical problems, we have designed a powder vibrating screen. Utility Model Content

[0005] The purpose of this utility model is to provide a powder vibrating screen that has the advantages of material leveling and dust removal, solving the problem that materials are prone to accumulation, which leads to the inability to quickly screen the accumulated materials, requiring the vibrating screen to work for a long time, reducing the screening efficiency, and also causing dust to be raised during the material distribution process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder vibrating screen, comprising a screening frame, with springs fixedly connected to the left and right sides of the front and rear sides of the screening frame, and a support column fixedly connected to the bottom of the springs; a screen mesh fixedly installed in the inner cavity of the screening frame; a vibrating motor fixedly installed at the center of the front and rear sides of the screening frame; a discharge port opened on the right side of the screening frame; a fixed frame fixedly installed at the center of the top of the screening frame; a dust collection component fixedly installed on the front side of the top of the fixed frame; the dust collection component includes a dust collection fan, with a T-connector at the dust collection end of the dust collection fan, and a dust collection hood connected to the bottom of the T-connector; a material spreading component fixedly installed at the center of the top of the fixed frame; the material spreading component includes a drive motor, with a material spreading plate fixedly connected to the output of the drive motor; and a cleaning component fixedly installed in the inner cavity of the fixed frame.

[0007] Preferably, the vacuum cleaner is fixedly installed on the front side of the top of the fixed frame, the dust outlet of the vacuum cleaner is connected to a dust collection box, a dust filter is embedded in the front side of the dust collection box, and the vacuum hood is located on the left and right sides of the fixed frame.

[0008] Preferably, the screen is inclined, the bottom of the screening frame is connected to a discharge hopper, and the spreading plate is inclined and parallel to the screen.

[0009] Preferably, the drive motor is fixedly installed at the center of the top of the fixing frame, and a shielding frame is fixedly installed at the top of the center of the surface of the material spreading plate, with a filter screen installed through the surface of the shielding frame.

[0010] Preferably, the cleaning assembly includes a mounting bracket, which is fixedly installed between the bottoms of the front and rear sides of the inner cavity of the fixed bracket, and the center of the mounting bracket is sleeved on the surface of the output shaft of the drive motor.

[0011] Preferably, a cleaning brush plate is fixedly installed on the outer surface of the mounting bracket, and cleaning bristles are fixedly installed on the bottom of the cleaning brush plate. The cleaning bristles are made of a rigid material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses the output shaft of a drive motor to rotate a spreading plate, which flattens the material and prevents it from piling up during the vibration screening process. This allows the material to be evenly discharged from the screen holes. During the material flattening process, a shielding frame prevents the powder from being thrown up, ensuring that the material is fully screened and thus improving the screening effect.

[0014] 2. This utility model uses a dust extraction fan to draw in the dust generated during the vibration screening process from the dust extraction hood and store it inside the dust collection box. The air is then discharged through the dust removal filter on the surface of the dust collection box, achieving an automatic dust removal effect. This prevents dust from being stirred up during the powder screening process and improves the comfort of the surrounding working environment. Attached Figure Description

[0021] Please see Figures 1-5 A powder vibrating screen includes a screening frame 1. Springs 2 are fixedly connected to the left and right sides of the front and rear sides of the screening frame 1. Support columns 3 are fixedly connected to the bottom of the springs 2. A screen 6 is fixedly installed in the inner cavity of the screening frame 1. A vibrating motor 4 is fixedly installed at the center of the front and rear sides of the screening frame 1. A discharge port 5 is opened on the right side of the screening frame 1. A fixed frame 7 is fixedly installed at the center of the top of the screening frame 1. A dust collection component 8 is fixedly installed on the front side of the top of the fixed frame 7. The dust collection component 8 includes a dust collection fan 81. The dust collection end of the dust collection fan 81 is connected to a three-way pipe 83. The bottom of the three-way pipe 83 is connected to a dust collection hood 84. A spreading component 9 is fixedly installed at the center of the top of the fixed frame 7. The spreading component 9 includes a drive motor 91. The output of the drive motor 91 is fixedly connected to a spreading plate 92. By setting the spreading plate 92, the powder can be spread evenly, so that the powder is uniform during the vibrating screening process and the powder screening efficiency is improved. A cleaning component 10 is fixedly installed in the inner cavity of the fixed frame 7.

[0022] Please see Figure 1 and Figure 3 The vacuum cleaner fan 81 is fixedly installed on the front side of the top of the fixed frame 7. The dust outlet of the vacuum cleaner fan 81 is connected to the dust collection box 82. A dust filter screen is embedded in the front side of the dust collection box 82. The dust filter screen can filter dust inside the dust collection box 82 and exhaust air. When it is necessary to discharge the dust inside the dust collection box 82, the dust filter screen can be removed to clean the dust inside the dust collection box 82. The vacuum cleaner hood 84 is located on the left and right sides of the fixed frame 7.

[0023] Please see Figure 1 The screen 6 is inclined, which allows the powder to move from the left and right to the discharge port 5 by gravity, thus facilitating the discharge of the material. The bottom of the screening frame 1 is connected to the discharge hopper 11, and the spreading plate 92 is inclined and parallel to the screen 6.

[0024] Please see Figure 3 , Figure 4 and Figure 5The drive motor 91 is fixedly installed at the center of the top of the fixed frame 7. A shielding frame 93 is fixedly installed at the top of the center of the surface of the spreading plate 92. By setting the shielding frame 93, the spread material can be shielded to prevent it from being sucked in from the dust hood 84. A filter screen 94 is installed through the surface of the shielding frame 93. By setting the filter screen 94, dust in the powder can be easily passed through and sucked in by the dust hood 84.

[0025] Please see Figure 5 The cleaning assembly 10 includes a mounting bracket 101, which is fixedly installed between the bottoms of the front and rear sides of the inner cavity of the fixing bracket 7, and the center of the mounting bracket 101 is sleeved on the surface of the output shaft of the drive motor 91.

[0026] Please see Figure 5 A cleaning brush plate 102 is fixedly installed on the outer surface of the mounting bracket 101. Cleaning bristles are fixedly installed on the bottom of the cleaning brush plate 102. The cleaning bristles are made of rigid material, and the bottom of the cleaning bristles is in contact with the top of the filter screen 94.

[0027] In use, the powder is placed above the screen 6, and then the vibration motor 4 is started. The vibration motor 4 causes the screening frame 1 to vibrate, thus vibrating and screening the powder. At the same time, the output shaft of the drive motor 91 drives the spreading plate 92 to rotate, spreading the material evenly so that the material does not accumulate during the vibration screening process. This allows the material to be discharged evenly from the screen holes of the screen 6. During the material spreading process, the shielding frame 93 blocks the powder from being thrown up, ensuring that the material is fully screened. The powder passing through the screen 6 is discharged from the discharge hopper 11, and the powder above the screen 6 is discharged from the discharge port 5. At the same time, the dust suction fan 81 works to suck out the dust generated during the vibration screening process through the filter screen 94. The dust suction hood 84 sucks the dust into the dust collection box 82 for storage. The air is discharged through the dust removal filter on the surface of the dust collection box 82, achieving an automatic dust removal effect. As the filter screen 94 rotates, it continuously contacts the top of the cleaning brush plate 102 for cleaning, thus achieving a cleaning effect.

[0028] In summary, this powder vibrating screen, through the cooperation of the vibrating motor 4, screen 6, dust collection component 8, material spreading component 9, and cleaning component 10, solves the problem of material accumulation, which leads to the inability to quickly screen the accumulated material, requiring the vibrating screen to work for a long time, reducing screening efficiency, and also the problem of dust being raised during the vibrating screening process.
