Description

Grinding disc base

Technical Field

The invention relates to the technical field of vertical roller grinding, in particular to a grinding disc base.

Background

Slag fed by a vertical mill falls to the middle of a millstone to form a conical material pile, the slag gradually scatters towards the periphery of the millstone under the action of centrifugal force along with the rotation of the millstone and enters a rolling area of the millstone and the grinding roller, the ground finished product or semi-finished product fine powder continuously moves towards the edge of the millstone to form an inclined material slope with a high outer part and a low inner part, the finished product or semi-finished product fine powder enters an outlet of a blowing ring along the inclined slope, a part of the finished product or semi-finished product fine powder upwards enters a separation area and a part of the finished product or semi-finished product fine powder downwards becomes a returned material under the action of high-speed hot air, because the slag contains iron sand, the specific gravity of the iron is greater than that of the slag, compared with the slag powder, the iron sand or the rolled iron sand powder is easy to deposit on the bottom layer of the material slope in the inclined material slope formed at the edge of the millstone, namely, resulting in a decrease in the grindability of the material.

Chinese patent No. CN201921724U discloses a millstone of a slag vertical mill, which comprises a millstone body, a lining plate and a material retaining ring, wherein the outer ends of the millstone body and the lining plate are respectively provided with millstone holes and lining plate holes. The iron sand is removed in time at the position where the iron sand is most likely to be accumulated in the slag grinding bed, and the grindability of the slag is improved.

The big end of the liner plate hole is arranged below, the small end of the liner plate hole faces upwards, but after the liner plate hole is blocked, the liner plate hole cannot be dredged, so that the iron sand cannot be discharged in time.

Disclosure of Invention

The invention aims to provide a grinding disc base, which achieves the purpose of conveniently cleaning a blockage after a lining plate hole is blocked.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides a mill base, includes mill disk body, welt and keeps off the material ring, mill disk body and the outer tip of welt are equipped with mill disk hole and welt hole respectively, mill disk hole and welt hole communicate with each other, mill hole aperture is greater than the aperture of welt hole, the downthehole annular thickening ring that laminates with welt hole wall that is equipped with of welt, the downthehole annular go-between of contradicting with mill hole pore wall that is equipped with of mill, the internal diameter of go-between is greater than the internal diameter of thickening ring, the go-between upper end is equipped with a plurality of supporting thickening ring at the downthehole limiting plate of welt, the downthehole locating part that.

Through adopting above-mentioned technical scheme, after the object blocks up the thickening ring, shift out the go-between from the mill downthehole through removing the spacing of locating part to the go-between, the thickening ring loses the support of spacing board this moment, shifts out from the welt is downthehole, and then convenient to use person clears up the interior object that blocks up of thickening ring, when in addition will thickening ring immigration welt hole, the thickening ring will laminate welt hole wall, conveniently shifts out the welt hole with the thickening ring again after the welt hole blocks up.

Preferably, one end of the connecting ring, which is far away from the thickening ring, extends out of the grinding disc hole, the limiting part comprises a fixed plate which is arranged at the lower end of the connecting ring and is abutted against the lower end wall of the grinding disc body, and a fastening screw rod which is in threaded connection with the grinding disc body is in threaded connection with the fixed plate.

Preferably, the limiting plate is detachably connected with the upper end of the connecting ring, the limiting plate is connected with the connecting rod in a threaded mode, and the connecting rod penetrates through the limiting plate and is connected with the upper end of the connecting ring in a threaded mode.

Preferably, the limiting plate includes the fixed plate of being connected with the connecting rod and sets up two first threaded rods on the fixed plate, each equal threaded connection has connecting sleeve on the first threaded rod, each the one end that first threaded rod was kept away from to the connecting sleeve is passed through the movable plate and is connected, connecting sleeve rotates with the movable plate and is connected, the movable plate supports the go-between.

Preferably, the liner plate hole is the bell mouth that upper end aperture is little, and lower extreme aperture is big, be equipped with the reinforcing plate that extends into the downthehole lining plate on the thickened ring outer wall, the reinforcing plate is close to the setting of abrasive disc hole.

In conclusion, the invention has the following beneficial effects: after the object blockked up the thickening ring, shifted out the go-between from the mill downthehole through removing the spacing of locating part to the go-between, the thickening ring loses the support of spacing board this moment, shifts out from the welt is downthehole, and then convenient to use person clears up the interior object of blockking up of thickening ring, when in addition with thickening ring immigration welt downthehole, the thickening ring will laminate welt hole wall, conveniently shifts out the thickening ring in welt hole wall again after the welt jam, simple structure, the practicality is good.
