Abstract

The invention discloses a roller press, particularly a frequency control single driving roller press. The roller press comprises a rack, a feeding device, a fixed roller and an action roller, wherein the fixed roller is fixed on the rack, and the fixed roller is driven to rotate by a first variable frequency motor through a standard speed reducer; the action roller is fixed on a rocker arm device, and is connected with a pressure device, and the action roller, the rocker arm device and the pressure device are fixed on the rack; and the feeding device is fixed on the rack. The included angle between a connecting line of the axes of the fixed roller and the action roller and the horizontal plane is 30-50 degrees. The grinding pressure, the rotation speed of the fixed roller and the feeding speed can all be controlled and adjusted on line by a control system, and an appointed material layer is fed into a grinding area according to the appointed feeding speed, and the height and the width of the material; and the energy utilization ratio in a crushing process is improved by the uniform and ideal pre-ventilation; and compared with the existing roller press, the roller press disclosed by the invention can save energy by 30%, and compared with a ball grinding mill, the roller press disclosed by the invention can save energy by 70%.

Description

A kind of roll squeezer

Technical field

The present invention relates to a kind of milling equipment, particularly a kind of roll squeezer.

Background technology

Roll squeezer; Have another name called squeezing mill, roll-in mill; Be last century the mid-80 at first develop appearance by Germany; This equipment and ball mill be supporting usedly can to reduce by 25%～40% with the specific yield power consumption of mill during cement, output increases by 40%～60%, abrasive body consumption reduces by 60%, and economic benefit is quite remarkable, therefore by universally acknowledged for being one of state-of-the-art milling equipment in the world.

Traditional roll squeezer mainly is by frame, be located at a fixed roll on the frame, action roller, be located at action roller one side along continuous straight runs pushes two group oil cylinders of roller and is located at two groups of drive units that the frame outside drives fixed roll and action roller respectively and constitute, and its drive unit is to be made up of motor, Hooks coupling universal coupling and planetary reduction gear.

The problem that this conventional roll press exists is: the charging angle of (1) two pressure roller formation is big; Make the charging aperture place have excess material; Not only can cause the heavy wear of pressure roller roll surface, consume a large amount of power, and can produce a large amount of heats and cause equipment seriously overheated; (2) two groups of drive units have not only increased equipment cost, and make device structure complicated, heavy, difficult installation, and also action roller is being with the reductor motion for a long time, and fault rate is higher; (3) two group oil cylinder operating pressures of pushing tow action roller are big, are difficult to realize synchronously, and action roller shaft is tilted easily, cause the axis of moving fixed two rollers not parallel, are prone to produce vibrations during work.

Summary of the invention

The objective of the invention is to solve the problems referred to above that prior art exists, provide a kind of angle little, the pressure roller roll surface is not easy to wear, and electrical consumption power is little, and simple in structure, low cost of manufacture is easy to promote the use of, the reliable roll squeezer of stable working.

For realizing above-mentioned purpose, the present invention has adopted following technical scheme: a kind of roll squeezer, comprise frame, feed arrangement, fixed roll and action roller, and said fixed roll is fixed on the frame, drives the fixed roll rotation by first variable-frequency motor through the standard decelerator; Said action roller is fixed on the rocker arrangement, links to each other with pressue device, is fixed on together on the frame; Said feed arrangement is fixed on the frame.

The axial connecting line of said fixed roll and action roller and the angle of horizontal plane are 30～50 degree.

Said action roller is a dancer, and itself and fixed roll keep certain roll gap mutual extrusion material.

Said feed arrangement drives running through second variable-frequency motor.

Said first variable-frequency motor and second variable-frequency motor can be regulated rotating speed through the outer control system of frame.

First variable-frequency motor drives the fixed roll rotation through the standard decelerator; Second variable-frequency motor drives feed arrangement material is sent into the grinding district between fixed roll and action roller; Pressue device pressurizes to action roller through rocker arrangement, through the material in high pressure crushing grinding district, from the frictional force drive action roller rotation of material; The axial connecting line of fixed roll and action roller and the angle of horizontal plane are 30～50 degree; Grinding pressure, fixed roll rotating speed and rate of feeding all can make and specify the bed of material to enter into the grinding district according to rate of feeding and the height of materials and the width of appointment through the On-line Control adjustment of control system; All even desirable preparatory ventilation has guaranteed perfect capacity usage ratio in the crushing process; Compare with existing roll squeezer, can be energy-conservation up to 30%, it is energy-conservation even up to 70% to compare ball mill.

In the accompanying drawing: 1-first variable-frequency motor; 2-standard decelerator; The 3-fixed roll; The 4-action roller; The 5-rocker arrangement; The 6-pressue device; 7-second variable-frequency motor; The 8-feed arrangement; The 9-frame; 10-controls system.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the present invention is done further explain.

As shown in the figure; The present invention includes first variable-frequency motor (1), standard decelerator (2), fixed roll (3), action roller (4), rocker arrangement (5), pressue device (6), second variable-frequency motor (7), feed arrangement (8), frame (9) and control system (10); Described fixed roll (3) is fixed on the frame (9); Action roller (4) is fixed on the rocker arrangement (5); rocker arrangement (5) links to each other with pressue device and is fixed on the frame (9), and feed arrangement (8) is fixed on the frame (9); First variable-frequency motor (1) has been formed transmission system with standard decelerator (2), and it drives fixed roll (3) rotation, and the axial connecting line of fixed roll and action roller and the angle of horizontal plane are 30～50 degree.

Have only one group of transmission system not only to reduce equipment cost, and simplified device structure, the convenient installation adopted the standard decelerator, selects for use conveniently, practiced thrift cost.Material can will be specified bed of material low-angle feeding grinding district according to the height of materials and the width of appointment through the controlled feed rate of feed arrangement (8), guarantee the perfect capacity usage ratio in the crushing process through preparatory ventilation, reduce wearing and tearing and energy consumption widely; Action roller (4) fully synchronously, has thoroughly solved conventional roll press action roller roll shaft and has tilted, moves the uneven problem of fixed roll through rocker arrangement (5) entire pressurisation, has reduced vibration; Fixed roll (3), action roller (4) grinding pressure and feed arrangement (8) rate of feeding all can be through control system (10) On-line Control adjustment.

More than be preferred forms of the present invention, according to content disclosed by the invention, those of ordinary skill in the art can conspicuously expect some identical, replacement schemes, all should fall into the scope of the present invention's protection.
