The lever-type multi-roll grinding machine is universally applied to a Raymond mill and a ring roll mill, the grinding force between the grinder roll and the grinder ring can be greatly increased, and the grinding efficiency is higher.
Description
(1) technical field:
The present invention relates to the powder process equipment, be specially the multiple roller flour mill of a kind of lever.
(2) background technology:
Flour mill is breeze sector application equipment the most widely, and wherein the most representative equipment is raymond mill and ring roller mill.The operation principle of raymond mill and ring roller mill is that the grinding roller assembly with exocentric structure is set on swivel mount, the grinding roller assembly makes grinding roller lean on centrifugal action on bull ring in the swivel mount rotation process, grinding roller rolls on bull ring, between the two mutually roll and by crushing material.
The grinding roller assembly of described raymond mill is by linkage in the upper even hanging of swivel mount (be commonly called as the fixed roll frame, install in main frame main shaft upper end), and grinding roller assembly and central axes also are circle distribution; Described ring roller grinds the grinding roller of grinding roller assembly in the upper arranging multiplayer of swivel mount (being commonly called as rolling disc), every layer of grinding roller circumference uniform distribution, and each grinding roller is placed on the shaft of grinding roller of swivel mount.
From said structure, can find out, the centrifugal force of raymond mill and ring roller mill grinding roller assembly produces direction for radially, in the situation that the design considerations such as the rotating speed of swivel mount (being main shaft) and grinding roller quality are constant, the centrifugal force constant magnitude produced, but will improve centrifugal force and increase production capacity, only be improved rotating speed, result is to cause the equipment overload operation, machine vibration is large, the life-span is short, and this is a kind of acts and efforts for expediency mode, can not be for a long time for it.
Therefore, how further increasing the grinding pressure of grinding roller to bull ring, further improve production capacity, is that raymond mill and ring roller grind problem anxious to be resolved.
(3) summary of the invention:
For this reason, the present invention proposes the multiple roller flour mill of a kind of lever, the structural design by the grinding roller assembly is also introduced the leverage counterweight, increases substantially the grinding roller grinding pressure, reaches the purpose of enhancing production capacities.
Can realize the multiple roller flour mill of lever of above-mentioned purpose, comprise two covers that are equipped with bull ring or overlap the grinding roller boosting mechanism more, described grinding roller boosting mechanism circumference uniform distribution is installed on the swivel mount of main shaft, every cover grinding roller boosting mechanism comprises grinding roller, counterweight roller, grinding roller frame and lever bracket, described grinding roller frame is inclined to radially in the other direction to the rotation of swivel mount, the inner of grinding roller frame is hinged in swivel mount by grinding roller frame pivot pin, and described grinding roller is hinged in grinding roller frame outer end by the grinding roller pivot pin; Along the swivel mount rotation direction, after described counterweight roller is located at grinding roller, described lever bracket is located between grinding roller and counterweight roller, and lever bracket front end and grinding roller frame outer end are connected, and the counterweight roller is installed in the lever bracket rear end.
Described counterweight roller has two kinds of functions:
1, described counterweight roller is hinged in the lever bracket rear end by counterweight roll shaft pin and contacts with bull ring.
Described counterweight roller participates in rolling, and the centrifugal force of its generation is amplified at double after-appliedly on grinding roller by lever bracket simultaneously, with this, increases grinding roller pressure.
2, described counterweight roller be fixed on the lever bracket rear end and with bull ring from.
Described counterweight roller does not participate in rolling, and just the centrifugal force of its generation is amplified at double after-appliedly on grinding roller by lever bracket, with this, increases grinding roller pressure.
For further increasing grinding roller pressure, be provided with the thrust mechanism to the bull ring pushing by grinding roller between described swivel mount and grinding roller frame or between swivel mount and lever bracket.
For simplified structure, can replace with rocker (rigidly connected) grinding roller frame and lever bracket and become the bracing frame of grinding roller and counterweight roller.
For adapting to the use of raymond mill, described institute grinding roller is made as one deck, and for adapting to the use of ring roller mill, described grinding roller can be made as two-layer or multilayer; Corresponding, on described bull ring, offer and one deck, two-layer or the multilayer grinding roller is corresponding one, two or more pieces mill road.
Advantage of the present invention:
1, the multiple roller flour mill of lever of the present invention, by design grinding roller boosting mechanism, increases substantially the grinding pressure between grinding roller and bull ring, makes material more easily broken, and abrasive dust efficiency is higher.
2, the present invention can be general on raymond mill and ring roller mill, simplified the grinding roller mechanism structure of raymond mill and ring roller mill, reduced cost of manufacture, is easy to installation and maintenance.
(4) accompanying drawing explanation:
