Description

Spreading formula mineral fine shaping apparatus

The utility model relates to a kind of granular material make-up machine, specifically is spreading formula mineral fine shaping apparatus.

China is the consumption big country of coal production.Directly not only the thermal efficiency is not high for the burning raw coal, and is and seriously polluted, therefore adopts advanced technology and drawing method that raw coal is processed into to have given shape, the moulded coal of size, intensity and physicochemical property just becomes the strategic task of China.In recent years, obtaining gratifying achievement aspect the technology of moulded coal, but the development of former makes slow progress, the moulding facility still have bigger defective, thereby have seriously restricted the progress of the popularization of moulded coal suitability for industrialized production and moulded coal.Domestic make-up machine mainly contains pair roller type and spiral squeezing type two big classes at present.It is less that the pair roller type make-up machine has energy consumption, operate steadily, and simple operation and other advantages, but exist briquetting pressure low, can not regulate and control, release property is poor, only depending on deadweight to fall, and tough breeze can't the demoulding, and the pair roller wearing and tearing are big, the maintenance cost height, and ratio of briquetting is low, shortcomings such as briquette strength difference.The spiral squeezing type make-up machine has the briquetting pressure height, and ratio of briquetting advantages of higher, but have the energy consumption height is easy to generate overload, stuck head especially, must shut down and fix a breakdown, and shortcoming such as is difficult for steadily, work continuously.

The purpose of this utility model just provides a kind of compaction type mineral fine shaping apparatus, has broken through the tactic pattern of above-mentioned two class make-up machines in design fully, and it is big to have briquetting pressure, and demolding performace is good, and it is reliable to operate steadily, and energy consumption is low, the advantage of compact conformation.

The technical solution of the utility model is: mainly be by transmission mechanism; rolling body and mould emptier constitute; the movement parts that is driven rolling wheel and with groove by transmission mechanism is synchronized with the movement; wherein the groove of rolling wheel and movement parts cooperates formation spreading mechanism; movement parts is a shuttling movement in vertical plane; movable floor is arranged at the bottom at the groove of movement parts, and the core bar of band spring is housed on the base plate, and projection formation mould emptier is arranged in demoulding position and core bar corresponding position.

In technique scheme, the movement parts that transmission mechanism drives rolling wheel and with groove is synchronized with the movement, continuously the movement parts of operation at first feed zone in hopper below by the time, powder progressively fills up in the groove on the movement parts because of deadweight or mechanism, run to shaping area rolling wheel below then, type piece into strips after the spreading of rolling wheel, and then by demoulding district, be that movement parts moves to and makes groove opening down, demoulding core bar just cooperates with projection, under the effect of projection, core bar drives movable floor and moves downwards, the demoulding of repulsive-type maglev bar falls on the driving-belt to be sent, and spring drives core bar resets movable floor, prepares to work next time.

The groove of movement parts of the present utility model is wide at the top and narrow at the bottom trapezoidal, powder is inserted in the trapezoidal groove wide at the top and narrow at the bottom like this, operating rolling wheel with material in groove from the spreading of h height to hn height, thereby material volume in groove is compressed and closely knit moulding, therefore, the utility model can carry out different choice and collocation by material height before and after shape, size, gradient and the spreading of groove, operational characteristic according to breeze is controlled the moulding compression ratio quantitatively, the size of type piece, shape etc. reach predetermined molding effect.The existing make-up machine of this feature can't be accomplished.Filler of the present utility model is to utilize the gravity powder to fill up groove naturally basically, the powder forming process all is confined in the moulding groove, material and moulding facility have only very short-range moving and friction, so useless power consumption seldom, reach when being equal to shaping strength, energy consumption of the present utility model is significantly less than screw extruder, is that it is below 1/4.Simultaneously, movable floor is adopted in the bottom of the utility model moulding groove, in demoulding position, movable floor is downward repulsive-type maglev bar under the projection effect, make its both sides break away from dovetail groove, molding materials will break away from base plate automatically by the effect of gravity and operational shock then, fall on the discharging conveyer belt, this mechanical forced demoulding action has fundamentally solved a crucial difficult problem that is difficult for the demoulding after the high powder moulding of viscosity.

Movement parts of the present utility model is a crawler type moulding carrier bar.Can be circular sheave also, thereby constitute two kinds of different embodiment.

Therefore, the compaction type mineral fine shaping apparatus that the utility model provides has been broken through the tactic pattern of existing make-up machine in design fully, designed in hopper calendering forming with powder volume adjustable ratio, utilize the movable floor ejection device, fundamentally overcome the intrinsic defective of existing make-up machine, technical performance improves greatly, has following characteristics;

1, briquetting pressure is big, and can be according to the shape of different operating modes to moulded coal, and size and volume compression ratio are regulated and control;

2, has good, reliable demolding performace;

3, operate steadily reliably, easy and simple to handle, can work continuously;

4, energy consumption is low, and moulded coal power consumption per ton is below 3KW:

5, compact conformation, institute takes up space few, and installation and maintenance are easy.
