Abstract
The invention relates to a material preparing device for a roller press. The material preparing device is characterized in that a rationing belt weigher is correspondingly arranged below a material outlet of a material bin, and a material layer thickness measuring instrument is positioned above the rationing belt weigher; a fixed roller is correspondingly arranged below a discharging part of the rationing belt weigher, and a material level measuring instrument is fixed on a rationing material bin. The material preparing device provided by the invention has the advantages that a scheduled material layer is prepared, the material layer is conveyed on a roller loading surface t reasonable speed, gas in the material layer is effectively eliminated, the technical cost is remarkably reduced, the technological loss of the machine is reduced, so that the energy use ratio in smashing is improved by 1.3-1.4 times, the limitation for lineal pressure of the roller press is canceled, the limitation for the rolling speed of the roller press is canceled, when the linear through put-speed characteristic is fully utilized, the lineal pressure can achieve 7.5kN/mm, the roller speed can achieve more than 3m/s, and thus, the high throughput is realized through the small and light equipment.
Description
Technical field
The present invention relates to a kind of roll squeezer technical field, relate in particular to a kind of feed preparing device of roll squeezer.
Background technology
Roll squeezer adopted feed bin forced feed in the past, necessarily require roll squeezer top to form the stable operation that enough material are pressed guarantee roll squeezer, but in the stock column of forced feed, often containing a large amount of gas cannot get rid of, and the complicated applied force relation brought of material overflow, roll squeezer steady operation pressure can only reach 4kN/mm, roll squeezer causes roller rotating speed to start through having the throughput-speed characteristics of more or less successively decreasing from 1m/s according to the form of roll surface stressing conditions and material to be milled, and this characteristic is simultaneously relevant to unit energy increase in demand, so the roll surface speed of roll squeezer is limited to 1 ~ 1.5m/s in pure economic cause.Therefore in order to increase throughput, conventional roll press can only be by increasing the wide and roller footpath of roller, but based on manufacturing and economic cause, roller specification maximizes and is restricted.
Summary of the invention
For above problem the present invention, be to break through the restriction of existing roll squeezer to line pressure and roller speed, provide a kind of relatively little and lighter equipment to realize the feed preparing device of the roll squeezer of high throughput.
In order overcoming the above problems, to the invention provides a kind of roll squeezer feed preparing device, to comprise frame, it is characterized in that: also comprise fixed roll, thickness of feed layer measuring instrument, rationing belt conveyer scale, feed bin, level indicator;
Described fixed roll, thickness of feed layer measuring instrument, rationing belt conveyer scale, feed bin, level indicator are all fixed in frame; Rationing belt conveyer scale correspondence is arranged on the below, material outlet place of feed bin, and thickness of feed layer measuring instrument is positioned at rationing belt conveyer scale top, and fixed roll correspondence is arranged on the discharging place below of rationing belt conveyer scale, and level indicator is fixed on rationing feed bin.
The present invention is applied in as the preparation predetermined thickness of roller press and the bed of material of speed, not only prepared the predetermined bed of material, and can be transported on roller loading surface with rational speed, effectively got rid of the gas in the bed of material, can significantly reduce technical fee, by reducing mechanical technique loss (size of idle torque), prove 1.3 ~ 1.4 times of capacity usage ratios while having improved pulverizing, therefore not only cancelled the restriction that roll squeezer presses online, and cancelled the restriction to roll squeezer roller speed, when utilizing linear throughput-speed characteristics completely, line pressure can reach 7.5kN/mm, more than roller scooter 3m/s, therefore can realize high throughput by relatively little and lighter equipment.
Described rationing belt conveyer scale has independently drive unit, and transporting velocity can regulate continuously.
For fear of piling up and stopping up, the rotating speed of described fixed roll rotating ratio rationing belt conveyer scale is high by 3 ~ 6%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In Fig. 1: 1-frame; 2-fixed roll; 3-thickness of feed layer measuring instrument; 4-rationing belt conveyer scale; 5-feed bin; 6-level indicator.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the invention provides a kind of roll squeezer feed preparing device, comprise frame 1, fixed roll 2, thickness of feed layer measuring instrument 3, rationing belt conveyer scale 4, feed bin 5, level indicator 6;
Described fixed roll 2, thickness of feed layer measuring instrument 3, rationing belt conveyer scale 4, feed bin 5, level indicator 6 are all fixed in frame 1; Rationing belt conveyer scale 4 correspondences are arranged on the below, material outlet place of feed bin 2, thickness of feed layer measuring instrument 3 is positioned at rationing belt conveyer scale 4 tops, fixed roll 2 correspondences are arranged on the discharging place below of rationing belt conveyer scale 4, and level indicator 6 is fixed on rationing feed bin 5.
Described rationing belt conveyer scale 4 has independently drive unit.
1, the rotating speed of described fixed roll 2 rotating ratio rationing belt conveyer scales 4 is high by 3 ~ 6%.
During roll squeezer work, material sets out by the rationing feed bin 5 that controlled by level indicator 6, enter the rationing belt conveyer scale 4 of variable ratio frequency changer speed governing, the thickness of feed layer measuring instrument 3 of installing by its top is measured thickness of feed layer, by rationing belt conveyer scale 4, material is accelerated to fixed roll peripheral velocity, the bed of material with predetermined thickness and speed finally preparing is sent into the fixed roll 2 with blocking material ring, for follow-up roll squeezer, can load easily and operation stably.
The present invention is applied in the material preparation of roll squeezer, the bed of material of getting ready is fed into within the scope of adjustable fixed roll 2 summits of blocking material ring rotating speed, be accelerated to roller speed and be transported to continuously in roll gap, break through the restriction of conventional roll press to line pressure and roller speed, line pressure is brought up to 7.5kN/mm(power/roll gap length from 5 kN/mm), more than roller speed is brought up to 3m/s from 1.5m/s, thus the capacity usage ratio while significantly improving grinding 1.3 standby more than, that improves equipment can mastery.
The foregoing is only the preferred embodiments of the present invention, be not restricted to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present invention.
