Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for white fused alumina production, specifically to filtration equipment for white fused alumina production. Background Technology

[0002] White fused alumina is widely used in abrasives, refractory materials and many other fields due to its high hardness, good wear resistance and chemical stability. Different application scenarios have strict requirements on the particle size of white fused alumina particles. For example, in precision grinding, small and uniform white fused alumina particles are required to make the machined surface smooth. In refractory material manufacturing, there may be specific requirements on the particle size distribution range in order to optimize the material performance.

[0003] Traditional white fused alumina screening methods often employ vibrating flat screens. The screening area of ​​a flat screen is relatively fixed, limiting the distribution and movement path of white fused alumina particles on the screen. This results in some particles failing to make sufficient contact with the screen, leading to inadequate screening and affecting the screening quality. Furthermore, when using a flat screen to filter white fused alumina particles of different sizes, the screened particles need to be placed on different screens for further filtration, requiring multiple screenings, which is extremely inconvenient.

[0004] To address the aforementioned issues, we propose a filtration system for white fused alumina production. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for the production of white fused alumina, so as to solve the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for white corundum production, comprising a vibrating box, wherein filter tubes are installed at equal intervals vertically through openings at the top and bottom of the vibrating box, and vertical positioning columns are provided inside the filter tubes. Three spiral ribbon screen channels are fixedly provided on the outer wall of the positioning columns. A spiral ribbon screen plate is installed on the top outer wall of the spiral ribbon screen channel, and the outer wall of the spiral ribbon screen plate is fixedly connected to the inner wall of the filter tube. A storage box is installed on the bottom outer wall of the spiral ribbon screen channel through an opening, and a downwardly inclined discharge pipe is connected to the bottom outer wall of the storage box through an opening.

[0007] Preferably, the three spiral ribbon screen channels on the positioning column have spiral ribbon screen plates at the top with progressively increasing apertures from top to bottom.

[0008] Preferably, the outer wall of the positioning post is fixedly provided with equidistant fixing rings, the outer wall of the fixing rings is fixedly connected to the inner wall of the filter tube through a bracket, and the central axis of the positioning post and the circumferential axis of the filter tube are on the same straight line.

[0009] Preferably, a feeding hopper is fixedly provided on the top outer wall of the filter tube, and a discharge pipe is installed on the bottom outer wall of the filter tube through an opening.

[0010] Preferably, the vibration box has a base at its bottom, a skirt is fixedly provided on the bottom outer wall of the vibration box, a first support column is fixedly provided on the bottom outer wall of the skirt, and a second support column is fixedly provided on the top outer wall of the base, with springs connected to the bottom of the first support column and the top of the second support column.

[0011] Preferably, two vibration motors are installed on the bottom outer wall of the vibration box, and the two vibration motors are connected to a power switch via wires, and the power switch is connected to a power cord.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] White fused alumina is added into the filter tube through the feeding hopper. The white fused alumina particles fall down along the spiral direction of the spiral ribbon screen plate in the filter tube. The screened white fused alumina particles fall into the spiral ribbon screen channel. Due to its unique spiral ribbon structure, the area of ​​white fused alumina particles that are filtered is greatly increased, which is conducive to improving the screening quality of white fused alumina particles.

[0014] Furthermore, through the three-section spiral ribbon screen plate, white corundum particles with a diameter larger than the current spiral ribbon screen plate aperture cannot pass through and will continue to move downwards along the spiral ribbon screen plate until they reach the bottom spiral ribbon screen plate, where they will be discharged from the discharge pipe at the bottom of the filter tube. It can also classify and filter white corundum particles of different sizes at one time. Attached Figure Description

Fixing rings 10 are fixedly arranged at equal intervals on the outer wall of the positioning column 5. The outer wall of the fixing rings 10 is fixedly connected to the inner wall of the filter tube 2 through a bracket, which facilitates fixing the positioning column inside the filter tube 5. The central axis of the positioning column 5 and the circumferential axis of the filter tube 2 are on the same straight line.

[0029] Example 3

[0030] Based on Embodiment 1, a base 12 is provided at the bottom of the vibration box 1, a skirt 11 is fixedly provided on the bottom outer wall of the vibration box 1, and first support columns 13 are fixedly provided at equal intervals and vertically downward on the bottom outer wall of the skirt 11.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual appendix Figure 1-5 When using this utility model, the white corundum particles to be screened are first added from the feeding hopper 3 at the top of the filter tube 2, and then the vibration motor 16 is started, the vibration box 1 vibrates accordingly and drives the filter tube 2 to vibrate synchronously.

[0033] At this time, under the combined action of gravity and vibration, the white fused alumina particles fall along the spiral direction of the spiral ribbon screen plate 7 inside the filter tube 2. Since the aperture of the spiral ribbon screen plate 7 increases from top to bottom, during the falling process, white fused alumina particles with a particle size smaller than the current aperture of the spiral ribbon screen plate 7 will pass through the screen plate 7 and fall into the spiral ribbon screen channel 6 below, and eventually slide down into the storage box 8 along the screen channel 6, and then be discharged and collected through the discharge pipe 9; while white fused alumina particles with a particle size larger than the current aperture of the spiral ribbon screen plate 7 cannot pass through and will continue to move downward along the spiral ribbon screen plate 7 until they reach the bottom spiral ribbon screen plate 7. If they still cannot pass through, they will be discharged from the discharge pipe 4 at the bottom of the filter tube 2, thereby realizing multi-stage screening of white fused alumina particles and separating white fused alumina particles of different sizes.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
