The scraper is driven to rotate, so that sundries adhered to the filter screen are scraped by the scraper, the filter screen is ensured to be smooth, and the normal operation of the sand mill is not influenced.

Description

Sand mill with self-cleaning type filter screen

Technical Field

The utility model relates to a sand mill technical field specifically is a sand mill with self-cleaning type filter screen.

Background

The sand mill is also called bead mill, and is mainly used for wet grinding of chemical liquid products, and can be classified into a horizontal sand mill, a basket type sand mill, a vertical sand mill and the like according to the use performance. The machine mainly comprises a machine body, a grinding cylinder, a sand grinding disc (deflector rod), grinding media, a motor and a feeding pump, wherein the feeding speed is controlled by the feeding pump. The grinding media of the apparatus are generally classified into zirconia beads, glass beads, zirconium silicate beads, and the like.

The sand mill is the grinding equipment with the widest material adaptability, the most advanced and the highest efficiency, the grinding cavity is the narrowest, the deflector rod gap is the smallest, the grinding energy is the most intensive, and the continuous material processing and continuous discharging can be realized by matching with a high-performance cooling system and an automatic control system, so that the production efficiency is greatly improved.

The ejection of compact structure of traditional sand mill is through the grinding ball of independent filter screen filtration sand mill, and the diameter of filter screen is less than grinding ball, and the material diameter is littleer can pass through in the gap of filter screen. Because some powder can not dissolve, and can be along with the change of time, the separation of solvent and powder can appear in the mixture of powder and liquid in the outside of filter screen, makes the concentration of the powder of filter screen outside higher and higher, and the material can be glued the outside at the filter screen thereupon to block up the filter screen, influence the operation of equipment.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem in the background art, the utility model discloses a sand mill with self-cleaning type filter screen.

The utility model provides a sand mill with self-cleaning type filter screen, including grinding barrel body, be equipped with the filter screen in the grinding barrel body, still be equipped with a plurality of scraper blades in the grinding barrel body, through its rotation, strike off debris on the filter screen.

The scraper is driven to rotate, so that impurities adhered to the filter screen are scraped by the scraper, the filter screen is ensured to be smooth, and the normal operation of the sand mill is not influenced.

The concrete structure of scraper blade and filter screen does: the filter screen is the barrel, the scraper blade distribute in the filter screen is outside, its inboard with the filter screen is connected.

The traditional scraper blade needs an additional motor to drive the scraper blade to rotate, is complex in structure and high in cost, so that the problem is further improved and solved, and particularly, the scraper blade is rotationally connected with the filter screen. Rotor in the grinding vessel rotates, and the rotor drives the material and rotates, and it is rotatory to drive the scraper blade when the material pivoted, so sets up, the utility model discloses the structure is simpler to the cost is reduced.

The concrete structure that scraper blade and filter screen rotate to be connected does: the filter screen afterbody is equipped with the apron, the scraper blade is through linking the board and connecting, link the board with the apron rotates to be connected. The center of the connecting plate is provided with a rotating shaft, and the rotating shaft is rotatably connected with the cover plate through a bearing.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a front view of the present invention with a partial cutaway;

FIG. 2 is an enlarged view at A in FIG. 1;

in the figure: 1. grinding the cylinder body; 2. filtering with a screen; 3. a squeegee; 4. a cover plate; 5. connecting plates; 6. a rotating shaft; 7. a bearing; 8. and a rotor.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in figure 1 and figure 2, the utility model relates to a sand mill with self-cleaning type filter screen, including grinding barrel 1, the position that is close to the discharge gate in grinding barrel 1 is equipped with filter screen 2, and filter screen 2 is the barrel. The ground material passes through filter screen 2 and gets into the 2 inner chambers of filter screen, and the rethread pipeline is followed the discharge gate and is exported.

Still rotate on the filter screen 2 outside and be connected with a plurality of scraper blades 3, its inboard is connected with filter screen 2 for strike off the debris of 2 surfaces of filter screen, the concrete structure is: the tail part of the filter screen 2 is provided with a cover plate 4, and the scraper 3 is connected through a connecting plate 5. The central position of the connecting plate 5 is provided with a rotating shaft 6, the central position of the cover plate 4 is provided with a mounting hole and a bearing 7, and the rotating shaft 6 is inserted in the bearing 7.

The rotor 8 in the grinding barrel body 1 rotates, the rotor 8 drives the material to rotate, the scraper 3 is driven to rotate while the material rotates, and impurities adhered to the filter screen 2 are scraped, so that the filter screen 2 is ensured to be smooth, and the normal operation of a sand mill cannot be influenced.

And scraper blade 3 passes through material rotation drive, compares in traditional mode through extra motor drive, simple structure, and is with low costs.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the description, and must be determined according to the scope of the claims.
