Titanium white powder mechanical activation processing apparatus

Technical Field

The invention mainly relates to the field of ball milling machinery, in particular to a titanium dioxide mechanical activation treatment device.

Background

In the production of titanium dioxide, the raw material ore needs to be finely ground to activate the raw material ore. At present, the most common equipment for grinding titanium dioxide ore is a dry ball mill, and the ore is processed into powder with a size according with the collision grinding of auxiliary grinding balls, so that the materials are fully mixed during subsequent processing. At present, in order to ensure the consistency of material grinding, a plurality of sections of grinding cavities are usually separated by sieve plates in the ball mill, grinding balls with different diameters are arranged in the grinding cavities, and powder can be effectively refined through the grinding of multistage grinding cavities, so that the grinding particle size of raw materials is more uniform. But because it is separately through the sieve between a plurality of sections grinding chamber, the sieve receives the impact of grinding ball when grinding, and wearing and tearing are very fast, and in the preceding section grinding chamber the material that has reached the particle size standard difficult transition to follow-up grinding intracavity, cause grinding efficiency not high.

Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

As shown in fig. 1-2, the titanium dioxide mechanical activation treatment device provided by the invention comprises a frame body 1, wherein two ends of the frame body 1 are both fixedly provided with supports 11 through bolts, a cylinder body 2 is rotatably arranged between the two supports 11 through bearings, and the supports 11 are used as supports of the cylinder body 2, so that the cylinder body 2 can be supported by the supports 11 to ensure the rotation along the axis thereof. Feed inlet 21 is seted up to barrel 2 front end, feed inlet 21 one side has the blanking storehouse, the material pipe of blanking storehouse does not contact with barrel 2, and the blanking storehouse will be waited the raw materials of grinding and continuously carry in barrel 2 via feed inlet 21. A plurality of partition plates 22 are welded in the cylinder body 2 from front to back, the partition plates 22 divide the inside of the cylinder body 2 into a plurality of cylinder-shaped grinding cavities 23, and preferably, 5-10 grinding cavities 23 are arranged. All placed a plurality of grinding balls 26 in every grinding chamber 23, grinding ball 26's diameter diminishes in proper order from the grinding chamber 23 of front end to the grinding chamber 23 of rear end to satisfy the grinding demand of different particle diameter raw materials. Grind on the chamber 23 inner wall welding arc screen cloth 24, the opening 25 has been seted up to the one end that the arc screen cloth 24 of partition panel 22 and front side contacted, opening 25 is as the intercommunication mouth with next-level grinding chamber 23, and the convenient material that requires from the particle diameter complex after arc screen cloth 24 filters gets into wherein. In the last stage of grinding cavity, the side wall of the grinding cavity 23 where the arc-shaped screen 24 is located is provided with a guide outlet which is communicated with the inner cavity of the subsequent receiving barrel 3. The arc-shaped screens 24 are arranged in a staggered manner in the grinding cavities 23, so that materials are prevented from entering the grinding cavities 23 in a stepped manner, and the grinding effect is guaranteed. Specifically, the diameter of the sieve pore on the arc-shaped screen 24 decreases progressively from the front end of the grinding cavity 23 to the rear end of the grinding cavity 23, and the diameter of the grinding ball 26 in the grinding cavity 23 is greater than that of the sieve pore on the arc-shaped screen 24 in the grinding cavity 23, so that the grinding ball 26 is prevented from falling into the next grinding cavity from the sieve pore. The installation of 2 afterbody outsides of barrel body holds a section of thick bamboo 3, hold a section of thick bamboo 3 and cover the grinding chamber 23 of rearmost end, hold 3 bottoms of a section of thick bamboo and set up blanking mouth 31, hold the finished product material that grinding chamber 23 of rearmost end ground the completion and collect to lead to the conveyer belt through blanking mouth 31 and carry next process on. The bearing cylinder 3 is fixedly connected with the frame body 1 through a bolt, and the bearing cylinder 3 is connected with the cylinder body 2 in a sealing mode through a filled wear-resistant sealing strip. Prevent the dust material from overflowing from the gap. 1 front end bolt of support body installs driving motor 4 and transmission gear box 5, install ring tooth 12 on the 1 front end outer wall of barrel, driving motor 4 rotates with ring tooth 12's cooperation drive barrel 2 through transmission gear box 5.

This device becomes a plurality of grinding chamber through partition panel with the barrel interval to utilize the arc screen cloth that sets up on the barrel lateral wall as the communication between the two adjacent grinding chamber, the material that will accord with the particle diameter that can be more timely falls into next grinding intracavity, thereby realizes the hierarchical quick grinding of material.

Furthermore, the height of the front end of the cylinder body 2 is higher than that of the rear end of the cylinder body 2, so that the whole cylinder body 2 is inclined at a certain angle, and the included angle of 1-5 degrees is formed between the axis of the cylinder body 2 and the horizontal plane. Through inclining the barrel 2, the materials can be better filtered by the arc-shaped screen to enter the next grinding cavity.

Further, the arc-shaped screen 24 covers one quarter of the inner wall surface of the grinding cavity 23, and the arc-shaped screen 24 and the inner wall of the grinding cavity 23 are in smooth transition.
