Description

End position style grinding roller grinder

Technical field

The present invention relates to a kind of material grinding equipment, specifically is a kind of end position style grinding roller grinder.

Background technology

On February 2nd, 2005 was announced, application number is " 03235660.8 ", notification number is put wheel and is milled for the patent specification of " 2675258 " has disclosed a kind of end, this is milled and comprises mill tube, the mill tube bottom is provided with the mill tube supporting base, be provided with grinding roller in the mill tube, roll shaft and scraper plate and material guide device, one end of roll shaft is connected with an end of grinding roller, the other end of roll shaft stretches out outside the mill tube, which is provided with pressue device and roller support, the roll shaft that is grinding roller by an end connects realizes the location, the feed end of mill tube has feed arrangement, the discharge end of mill tube has discharging opening, and this end is put the rolling grinding tool has volume little, characteristics such as structure is simpler.This deficiency that exists of milling is that owing to just be provided with the mill tube supporting base in the mill tube bottom, to the unidirectional support of mill tube, therefore the easy generation of mill tube is upwards beated in operation process, causes that running is unstable, influences milling efficiency.

Summary of the invention

The purpose of this invention is to provide a kind of stable end position style grinding roller grinder that turns round.

Technical scheme of the present invention, comprise mill tube, the mill tube bottom is provided with the mill tube supporting base, one end of mill tube has end cap, be provided with grinding roller, roll shaft and scraper plate and material guide device in the mill tube, the inner of roll shaft is connected with an end of grinding roller, stretch out outside the end cap of this side the outer end of roll shaft, which is provided with pressue device and roller support, the roll shaft that is grinding roller by an end connects realizes the location, and described scraper plate is connected with end cap with material guide device, and the feed end of mill tube has feed arrangement, the discharge end of mill tube has discharging opening, and improved structure is:

The mill tube supporting member that can constitute circumferentially support, constraint to mill tube is set on the top of mill tube;

The other end of mill tube connects an annular element, and this annular element and mill tube are on the same axis, and this annular element outer end connects power transmission shaft, and power transmission shaft is provided with circumferential supporting member, and the rotation of power transmission shaft promptly drives annular element and mill tube rotates with respect to end cap.

Circumferential supporting member acting in conjunction on the mill tube supporting member on mill tube top and the mill tube supporting base of mill tube bottom and the power transmission shaft constitutes supporting, the constraint of circumferencial direction to mill tube.

Technique effect of the present invention is:

1, owing to is provided with the mill tube supporting member on mill tube top, on power transmission shaft, be provided with simultaneously circumferential supporting member, and act on mill tube by annular element, thereby mill tube supporting base and the mill tube supporting member on mill tube top and the circumferential supporting member acting in conjunction on the power transmission shaft by the mill tube bottom, constituted effective supporting and constraint, therefore can effectively stop mill tube to be beated, and reduced the vibration that produces because of beating the mill tube circumferencial direction, reduce fault rate, make that the mill tube running is stable;

2, when realizing the effect that mill tube turns round stable, can improve the mill tube rotating speed, the raising of mill tube rotating speed can increase the number of times that material is milled, and makes output improve; When revolution is high, can also improve the rolling speed of grinding roller to material, promptly the impulsive force that material is produced is big, makes raw meal particle size thinner.In addition, the mill tube rotating speed is higher, and the centrifugal force that material is subjected to is bigger, and promptly material is bigger with respect to the adhesive force of mill tube flour milling, makes the better effects if that material is rolled, and fineness is thinner, and output is higher.

3, because rotating, mill tube of the present invention adopt power transmission shaft to drive, with respect to the frame mode that adopts the gear drive mill tube, removed mill tube gear wheel and pinion structure and sealing thereof and cooling system, thereby simplified the structure, can reduce manufacturing cost, reduce the maintenance cost of equipment.

The present invention is further described below in conjunction with drawings and Examples.
