Aliva
Pulp shooting machine.In this main distinction is dry type spraying method and wet type spray method.
In the wet type spray method, hydraulic binder such as cement, lime or gypsum, add material such as gravel and sand accordingly and various concrete additive mixes with water before spraying.Then wet concrete whitewashing hydraulically or in rare stream technology is pneumatically flowed to nozzle in dense stream technology.In dense stream technology, before nozzle, dense stream is destroyed and by the various promoter of air flow delivery by pressure-air.Promoter is added to concrete by air before nozzle equally and is whitewashed in rare stream technology.
In the dry type spraying method with the dry type concrete formed by hydraulic binder, additive and various concrete additive whitewashing adding to concrete shotcrete machine the inside.Here in rare stream technology, pneumatically realize carrying.Water and promoter are transported to the nozzle front with staggering.
Add the concrete additive at nozzle place, especially promoter liquid ground dosage always at this.The additive of this liquid, especially curing accelerator generally are placed in the receptacle of whitewashing frame or pulp shooting machine.But a problem of the additive of this liquid is a storage stability, and this stability is not enough in many aspects, and additive can not be used after the long period storage.The concrete additive of this liquid has a relatively large volume in addition, therefore may have conveying and the feed problems that is fed to pulp shooting machine.
Therefore make additive in order to overcome stability problem, especially curing accelerator is transported to construction site and water dissolving on the spot there with powder shape.The curing accelerator that will contain liquid then is transported to the whitewashing frame and is used for similarly concrete is sprayed with the curing accelerator that has liquefied from the construction site.But this must an additional job step and the processing of Powdered promoter personnel are proposed high requirement and cause a strong dust load.Processing contains the promoter of liquid equally relatively apace after Powdered additive dissolving, because also may have stability problem here.
Summary of the invention
Therefore the objective of the invention is, in the pulp shooting machine of a kind of method of whitewashing and a kind of the above-mentioned type, can simply and when concrete sprays, not have stability problem ground processing additives by a pulp shooting machine fabrication of concrete.
According to the present invention, this point is achieved by the feature of claim 1.

In the accompanying drawing:
The schematic diagram of a pulp shooting machine of Fig. 1,
Schematic diagram of Fig. 2 according to mixing arrangement of the present invention,
Another schematic diagram of Fig. 3 according to mixing arrangement of the present invention.
The specific embodiment
Only illustrate in the accompanying drawing and be used for directly understanding critical piece of the present invention.
A pulp shooting machine 1 schematically and has very simplifiedly been described in Fig. 1.Such pulp shooting machine comprises a water and pressure air intake line 2, have the wheel 3 of the frame of travelling, filling funnel that is used for the delivering concrete whitewashing 4, a flexible pipe 5 and a nozzle that is connected with flexible pipe 6.This flexible pipe 5 also can be made by hard tube, but must be flexible in the zone of nozzle 6 at least, so that apply the concrete whitewashing.On this external pulp shooting machine 1 another pipeline 7 is set also, it leads in the flexible pipe in the zone of nozzle 6.In the wet type spray method, by pipeline 7 and additive carry air with staggering and in the dry type spraying method with additive stagger transporting water.
A mixing arrangement 8 that is used for additive also is set on pulp shooting machine 1, and it can directly be combined in the pulp shooting machine 1 or also can be connected with pulp shooting machine by unshowned pipeline.
The attached part of mixing arrangement 8 and pulp shooting machine 1 has been described in signal in Fig. 2.This mixing arrangement mainly comprises a storage container 10, a water inlet pipe road 9 and an agitator 11.In storage container 10, with powder or particle form fill concrete additive 12, preferably a kind of promoter.Common more known such additives are as curing accelerator, corrosion inhibitor, liquefier etc.For the concrete whitewashing, promoter is especially important, and it is by Sika
For example with title Sigunit
Sell.
Described container 10 is furnished with a hermetically enclosed cover plate in an advantageous manner, makes air moisture content can not enter into additive 12.A dosing mechanism 13, for example guiding valve or dosage screw rod, impeller gate etc. are responsible for Powdered additive 12 is metered in the agitator 11.Be arranged on the weighing device 14 if having the container 10 of Powdered additive 12, it is just enough then to use a guiding valve to carry out dosage.If use a dosage screw rod as dosing mechanism, then need not a weighing device 14.
Water is given agitator 11 by water inlet pipe road 9 by metering valve 15 dosages.Water also can intermediate storage in a unshowned container and place a given processing temperature there.For water is mixed with Powdered additive, use for example arm stirrer, disperser or revolution stator.The liquid additive mixture of Chan Shenging can be a kind of combination between a kind of solution, a kind of disperse means or solution and the disperse means like this.This point depends on the dissolubility of employed additive respectively.Advantageously, the disperse means that have than the additive of low solubility should have certain stability, for use in not precipitating when interrupting spraying process accidental.Need not ask dissolving fully, because the additive that is not easy to dissolve also may cause good result in the concrete whitewashing in water.
In agitator, the additive of any amount can be added in the water.The component of Powdered additive 12 is generally 5 to 95 weight % in water, be preferably preferred especially 40 to the 60 weight % of 40 to 80 weight %.
The mixture that contains liquid additive can pump from agitator 11 by a circulation line 16 and is pumped back to the agitator 11 again by being arranged on blend tool in the agitator 11, and this will improve mixing.A pump also can be set in circulation line, needn't in agitator, re-use blend tool thus.Also can select or in water inlet pipe road 9, in unshowned water intermediate storage tank, in agitator 11 and/or in pipeline 16, be provided with one or more unshowned heaters, by them the water of liquid additive mixture or input is heated to a higher temperature, especially be heated to a temperature more than 40 ℃, the viscosity that is used to improve the dissolubility of powder and influences the liquid additive mixture.
By an intake line 17 that directly comes out from agitator 11 or circulation line 16 branches, only carry the liquid additive mixtures to pipeline 7, this pipeline 7 flows to nozzle according to spraying method with water or air.A metering valve or a proportioning pump 18 can be set in intake line 17 for this reason, can regulate the amount of the liquid additive mixture that flows to concrete whitewashing by it.The liquid additive mixture of about 2 to 15 weight % of the hydraulic binder of 100 weight % in this will whitewash with respect to concrete flows to the concrete whitewashing.By concrete whitewashing and the diffusion that contains the hydraulic binder component therein, control the interpolation of liquid additive mixture thus.
Described mixing arrangement is by a unshowned computer control and regulating system operation.The definite of the conveying capacity of water, Powdered additive 12 and hydraulic binder can be by independently measuring appliance/counter realization or the direct relevant hydraulic binder realization of concrete whitewashing amount that realizes and pass through to be carried by dosing mechanism 13, weighing device 14, metering valve 15, metering valve 18.
The additive 12 that for example can be by flowing to agitator 11 and the amount of water are regulated desired mixing ratio.If from agitator, take out the certain amount of fluid additive agent mixture, can obtain the taking-up amount by the time of opening of adjusting metering valve 18 or by a unshowned measuring appliance by metering valve 18.Amount for compensation in agitator is taken out flows to agitator 11 with the amount of required additive 12 and water again by dosing mechanism 13 and metering valve 15.If additive uses up or will eliminate this fault when breaking down by water inlet pipe road transporting water, the storage volumes operator by agitator 11 also can stay a period of time that container 10 is full of.
Also can make the content of Powdered additive 12 in water at random be adjusted to above-mentioned limiting value by this method.Thus can fast reaction when hydraulic binder or the change of concrete whitewashing content.
In according to method of the present invention, the liquid additive mixture that not preprocessing is a large amount of, wherein the volume of agitator 11 is generally in 1 to 80 liter of scope.By the amount of pettiness and by only making required additive capacity liquefaction, there is not the stability problem of liquid additive in the method.In addition 1/2nd of the volume of the volume of Powdered additive when using liquid additive, produce less conveying cost and less carrying capacity of environment thus and make pulp shooting machine can have littler size.
In Fig. 3 by lasting agitator 19 for example extruder replace agitator 11 and circulation line 16 among Fig. 2.Such extruder has at least one mixing and conveying screw rod.For example also can use a mixed pole with hydrid component as lasting agitator, it is arranged on the hollow cylinder body the inside that a basic horizontal is provided with.Make the additive carried by dosing mechanism 13 and mix and similar to the above constitute a kind of solution and/or disperse means continuing the agitator the inside by the water that carry on water inlet pipe road 9.Needn't use proportioning pump 18 here, because described extruder 19 is born the function of conveying and dosing liquids additive agent mixture.Because realized an extraordinary mixing, so need not a circulation line by extruder 19.This extruder 19 can heat, the viscosity that is used to improve the dissolubility of powder and influences the liquid additive mixture.
Certainly shown in the present invention is not limited to and described embodiment.Described agitator also can be replaced by the parts of identical or similar functions with extruder.Replace Powdered additive also can use the additive or the moist powder of thickness, it is mixed into corresponding mixture content with water in mixing arrangement.But stability of attention problem possibly here.To have certain solid constituent of at least 1% for additive used in the present invention, preferably surpass 10% and especially preferably surpass 50% especially above 80%.
By use a plurality of mixing arrangements also can be individually in different mixing arrangements the mutual exclusive additive of processing or aforesaid moist or liquid slightly additive, especially this do not have stability problem with pulverous additive and flow to the concrete whitewashing.When using a plurality of mixing arrangement, they are provided with each other in parallel and make the liquid additive mixture flow to the concrete whitewashing individually or carry by a public pipeline.Also can make agitator 11 and lasting agitator 19 be combined in a mixing arrangement the inside and in parallel or be connected in series in order to mix better.
