Description

A kind of three-roll grinder for slurry grinding

Technical field

The utility model is related to grinder, more particularly to a kind of three-roll grinders for slurry grinding.

Background technology

Under normal circumstances, three-roll grinder usually all has cooling system, and cooling system is by setting abrasive roller At hollow form, and cooling water is passed through to cool down into it.But since the inner wall of abrasive roller is smooth, cooling water, which is passed through, to be ground After grinding roller, cooling water will not be rotated with the rotation of abrasive roller, and the surface for resulting in abrasive roller in this way cannot be same It is cooled down in one time, to make each lower part of abrasive roller generate the temperature difference with top, grinding will be reduced in the course of time The service life of roller.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of three-roll grinder for slurry grinding, the grindings Machine can improve the cooling efficiency of abrasive roller, extend the service life of abrasive roller.

To achieve the above object, the utility model provides technical solution below：A kind of three rollers for slurry grinding are ground Grinding machine, including rack are equipped with preliminary roller, central roll, back roller in the rack successively from front to back, and preliminary roller, central roll, back roller pass through respectively Three motor-driven rotations, preliminary roller, central roll, back roller rotating speed successively increase, and preliminary roller, back roller rotate clockwise, the central roll inverse time Needle rotates, and the rack is equipped with feeding equipment at preliminary roller, and rack is equipped with drawing mechanism at back roller, and drawing mechanism is close to back roller One end be equipped with discharging scraper, the preliminary roller, central roll are separately installed with abrasive roller in back roller, and 3 abrasive rollers are successively The inner wall of engagement, abrasive roller is equipped with groove, and the groove is twist distributed along the axis of abrasive roller, the preliminary roller, Central roll, back roller are hollow roller, and preliminary roller, central roll, back roller are connected to respective abrasive roller respectively, and preliminary roller, central roll, back roller Both ends be respectively equipped with water inlet and water outlet, 3 water inlets connect cooling water system by inlet valve, and 3 water outlets are logical Cross outlet valve connection return water system.

Preferably, feeding equipment includes feeding cylinder and the holder for fixing feeding cylinder, and the holder is fixedly mounted on In rack at preliminary roller position, the bottom of feeding cylinder is equipped with discharge port, and the top of feeding cylinder is equipped with feed inlet.

Preferably, the both sides of drawing mechanism are respectively equipped with left tapping channel and right tapping channel, left tapping channel and Right tapping channel is located at close to one end of abrasive roller at the both ends of abrasive roller.

Preferably, abrasive roller is made of zirconia material.

Using above-mentioned technical proposal, the utility model is equipped with groove on the inner wall of abrasive roller, and groove is along abrasive roller Axis be twist distributed, when being passed through cooling water into abrasive roller, on the one hand the spiral of groove can have cooling water There is certain stirring, so that various pieces water temperature of the cooling water in abrasive roller is consistent, avoid cold in abrasive roller But the non-uniform phenomenon of water distribution of water temperature, and cooling water can be upwards lifted with the rotation of groove, to abrasive roller It is cooled down at the top of inner wall.On the other hand the contact area for increasing cooling water and abrasive roller inner wall, grinds to improve The cooling velocity of roller is ground, and then extends the service life of abrasive roller.
