Description

A kind of building castoff that utilizes prepares mining lotion continuous stirring device for filling

Technical field

The utility model relates to mine equipment, especially relates to a kind of building castoff that utilizes and prepares mining lotion continuous stirring device for filling, belongs to the mine equipment technical field.

Background technology

Growing along with the quickening of Urbanization in China and town development, new countryside construction; The reconstruction of the old city town engineering is increasing; Thereby produced the discarded dismounting thing of a large amount of reconstruction of the old city town buildings; Like discarded concrete, useless masonry, useless building block etc., these building castoffs have had a strong impact on urban ecology and urban environment.In recent years; We combine with Coal Production to the comprehensive utilization of building castoff; Through a large amount of tests: the alternative sandstone of building castoff becomes the aggregate of making mining lotion, therefore, utilizes building castoff to prepare mining lotion continuous stirring device for filling and the preparation method has just produced.The utility model can reduce the exploitation to natural sandstone when utilizing building castoff in a large number, the sustainable development that has kept natural ecological and environment, simultaneously; Reduce enterprise's cost of winning, reduced energy consumption, alleviated labour intensity; Improve the downhole safety coefficient of production, reduced subsidence, solved " three next on press coal " problem; Improve the rate of to adopt, prolonged mine life, increased business economic benefit and social benefit.

At present, prior art is main with hydraulic fill mainly, is about to casting resin and in Filling Station, is prepared into solid-liquid two phase slurries; Adopt compression pump to carry then, to the down-hole, slurry dewaters voluntarily, drainage through discharge of pipes; Become obturation with certain intensity; Support and safeguard the rock mass around the goaf, prevent the rock mass avalanche, guarantee ordinary production.Prior art mostly adds natural sandstone, and investment is big, cost of production is high, when particularly excavating the casting resin of natural sand masonry, will destroy the natural environment and the ecological homeostasis.

Summary of the invention

The purpose of the utility model provides a kind of shortcoming that overcomes the casting resin of existing production technology excavation natural sand masonry, utilizes the fluidization operating principle to prepare the device for filling of lotion inserts filling underground goaf.

The utility model is that all kinds of buildings and industrial solid castoff are prepared into the lotion compound that has good stability superfine stage material, that satisfy the pumpability condition that contains necessarily less than 20 μ m; Design totally-enclosed super high pressure bend pipeline conveying system, be equipped with computer supervisory control system; Pumping filling underground goaf.

The beneficial effect of the utility model is: all kinds of buildings and industrial solid castoff be can handle in a large number, ground and working environment at coal mines improved, and energy conservation, and can obtain the high strength obturation, to safeguarding adjoining rock stability, it is very favourable to improve the mineral resource recovery rate.The utility model is applicable to that the colliery or the face of land can't build the non-ferrous metal in mine tailing storehouse, gold and other mining fillings, also is applicable to nuclear waste disposal and industrial waste physics (buried soverlay technique), therefore, has a extensive future.

For realizing above-mentioned purpose; The utility model has been taked following technical scheme: a kind of building castoff that utilizes prepares mining lotion continuous stirring device for filling; It comprises breaker, proportioning mixing plant, pipeline pumping installations, meausring apparatus, priming apparatus, computer central station of floating dock, feed bin, it is characterized in that: said breaker comprises one-level crushing engine and secondary breaker; Belt conveyor, vibrosieve.

Said proportioning mixing plant comprises opening conveying worm, continuous mixer, all-hydraulic twin-tub piston high-pressure delivery pump, hopper, pipeline.

Said pipeline pumping installations is made up of filling pump assembly, filling pipe, pipeline cleaning assembly, sedimentation basin.

Said feed bin comprises aggregate bin, glued feed bin, flyash storehouse, additive bin, sump, raw material heap storage, is respectively equipped with meausring apparatus, priming apparatus;

Said computer central station of floating dock is located at the central area of device.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation: in accompanying drawing 1: 1, one-level crushing engine; 2, secondary breaker; 3, belt conveyor; 4, vibrosieve; 5, aggregate bin; 6, continuous mixer; 7, opening conveying worm; 8, hopper; 9, all-hydraulic twin-tub piston high-pressure delivery pump; 10, pipeline; 11, computer central station of floating dock; 12, glued feed bin; 13, flyash storehouse; 14, additive bin; 15, sump; 16, meausring apparatus; 17, priming apparatus; 18, raw material heap storage.

The specific embodiment

Embodiment 1:

Present embodiment selects for use building castoff to make raw material.

During practical operation, earlier the building castoff of selecting for use is implemented broken.With loader building castoff is transported broken processing from raw material heap storage 18; Use one-level crushing engine 1, secondary breaker 2 to carry out fragmentation; Then; Broken material is delivered to vibrosieve 4 with belt conveyor 3 sieves, accept will get into aggregate bins 5 through belt conveyor 3, defective material then through back belt conveyor 3 return be crushed to once more qualified.

The building castoff that fragmentation is processed leaves the building castoff aggregate bin in, leaves flyash, cementitious matter, additive in flyash storehouse 13 interior, glued feed bins 12 interior, additive bins 14 respectively, and water leaves in the water storehouse 15.

The utility model Filling Station has been selected continuous mixer 6, and the design stowage capacity is 120m ³/ h, but continuous operation as required.The equipment of proportioning mixing plant design is two complete equipment, i.e. the using and the reserved.And concurrent working is by 11 controls of computer central station of floating dock.

The utility model proportioning stirring technique flow process specifically is divided into three steps:

The first step, feeds intake at continuously weighing.Four kinds of fillers through meausring apparatus 16, priming apparatus 17, weighing, feed intake, measure and can carry out continuously simultaneously, and get into continuous mixer 6 respectively through belt conveyor 3 and pipeline 10.

Second step, continuous stirring.After four kinds of fillers got into continuous mixer 6, continuous mixer 6 fully stirred by the mixing time of setting.

In the 3rd step, the discharging blowing is delivered to filling operation face through filling pipeline 10 continuously.When reaching the mixing time of setting; Continuous mixer 6 blowing mouths are opened; The finished product filling slurry is sent in the hopper 8 through opening conveying worm 7; Conduct oneself with dignity to all-hydraulic twin-tub piston high pressure packing delivery pump 9 feed by slurry, pressurization back filling slurry is delivered to filling operation face through filling pipeline 10.

For improving system's slurrying capacity, after the completion that feeds intake, promptly carry out next circulation weighing, the work that feeds intake, before a last circulation was stirred and accomplished, next circulation was ready to, and so continuous circulation is all accomplished until design objective.

Present embodiment selects for use building castoff to make raw material, in addition, also can select industrial solid castoffs such as gangue, industrial slags, cinder, mine tailing for use.In the manufacturing process, except that industrial slags, cinder self reason thing, chemical characteristic is different needs to adopt the different formulations, all the other manufacturing processes and to the material fineness requirement with embodiment 1, and undertaken by the technological process of production, all can obtain the utility model finished product at last.
