Abstract

The utility model discloses a roller press and particularly relates to a variable-frequency speed-regulation single drive roller press. The roller press comprises a rack, a material feeding device, a fixed roller and a movable roller, wherein the fixed roller is fixed on the rack and is driven to revolve by a first variable frequency motor through a standard speed reducer; the movable roller is fixed on a rocker device and connected with a pressure device; the movable roller and the pressure device are arranged on the rack together; and the material feeding device is fixed on the rack. An included angle between the axis connection line from the fixed roller to the movable roller and the horizontal surface is 30-50 degrees. The grinding pressure, the rotation speed of the fixed roller and the material feeding speed can be controlled and regulated on line through a control system; a designated material layer can be allowed to enter a powder grinding area according to designated material feeding speed, material height and width; the energy utilization rate during grinding is improved by uniform and ideal pre-change of air; and compared with the existing roller presses, the roller press disclosed by the utility model can save energy by 30% which is higher 70% than that of a ball mill.

Description

A kind of roll squeezer

Technical field

The utility model relates to a kind of milling equipment, particularly a kind of roll squeezer.

Background technology

Roll squeezer, have another name called squeezing mill, roll mill, be last century the mid-80 at first develop appearance by Germany, this equipment and ball mill be supporting usedly can to reduce the specific yield power consumption of mill during cement 25%～40%, output increases by 40%～60%, abrasive body consumption reduces by 60%, 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 respectively fixed roll and action roller and consist of, and its drive unit is to be made 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 large, so that there is excess material in the charging aperture place, not only can cause the heavy wear of pressure roller roll surface, consume a large amount of power, and can produce amount of heat and cause equipment seriously overheated; (2) two groups of drive units have not only increased equipment cost, and so that device structure is complicated, heavy, and difficulty is installed, and action roller is for a long time with the reductor motion, and fault rate is higher; (3) two group oil cylinder operating pressures of pushing tow action roller are large, are difficult to realize synchronously, and action roller shaft is tilted easily, cause the axis of moving fixed two rollers not parallel, easily produce vibrations during work.

The utility model content

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

For achieving the above object, the utility model has adopted following technical scheme: a kind of roll squeezer, comprise frame, feed arrangement, fixed roll and action roller, and described fixed roll is fixed on the frame, drives the fixed roll rotation by the first variable-frequency motor by the standard decelerator; Described action roller is fixed on the rocker arrangement, links to each other with pressue device, is fixed on together on the frame; Described feed arrangement is fixed on the frame.

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

Described action roller is dancer, and itself and fixed roll keep the mutual pressing materials of certain roll gap.

Described feed arrangement drives running by the second variable-frequency motor.

Described the first variable-frequency motor and the second variable-frequency motor can be by the outer control system adjusting rotary speeds of frame.

The first variable-frequency motor drives the fixed roll rotation by the standard decelerator, the second variable-frequency motor drives feed arrangement material is sent into grinding district between fixed roll and action roller, pressue device pressurizes to action roller by rocker arrangement, material by high pressure crushing grinding district, frictional force from material drives the action roller rotation, 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 be adjusted by the control system On-line Control, can according to rate of feeding and height of materials and the width of appointment, make and specify the bed of material to enter into the grinding district; All even desirable pre-ventilation has guaranteed perfect capacity usage ratio in the crushing process; Compare with existing roll squeezer, can be energy-conservation up to 30%, compare ball grinder saving energy even up to 70%.

Description of drawings

Fig. 1 is the structural representation of a kind of roll squeezer of the utility model.

Fig. 2 is the top view of a kind of roll squeezer of the utility model.

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

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in the figure, the utility model comprises the first variable-frequency motor (1), standard decelerator (2), fixed roll (3), action roller (4), rocker arrangement (5), pressue device (6), the 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); The first variable-frequency motor (1) has 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.

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

More than be preferred forms of the present utility model, according to the disclosed content of the utility model, those of ordinary skill in the art can apparently expect some identical, replacement schemes, all should fall into the scope of the utility model protection.
