Description

A kind of preparation facilities of building block

Technical field

The utility model relates to a kind of preparation facilities of building block, and particularly a kind of device for preparing haydite aerated concrete block belongs to the air entrained concrete manufacture technology field.

Background technology

At present, " energy-saving and emission-reduction " have become a fundamental state policy of China, ought to active response country call as the building trade with the energy rich and influential family, and therefore, air entrained concrete is widely applied throughout the country.But there are the shortcomings such as unit weight is large, drying shrinkage is large, intensity is low in common steam-pressing aero-concrete, and for improving this shortcoming, some producers adopt and add haydite in air entrained concrete.Admixture light-weight aggregate haydite in air entrained concrete, not only strengthen concrete skeleton structure, and can effectively keep the advantage of air entrained concrete, overcome its common quality defect, give full play of the heat-insulation and heat-preservation characteristic, become the new and effective walling of exterior wall peripheral structure self-heat conserving technology, will be applied widely.Its general method that adopts is that haydite and other components (cement, lime, gypsum, initiation agent, water etc.) are stirred into slip together, through get angry, quietly stop, the technique such as maintenance makes the haydite aerated concrete product.But because haydite is a kind of aglite of hollow, in whipping process, because the ratio of slip is great, haydite floats easily, causes skewness, forms product defects; On the other hand, because self intensity of haydite aggregate is lower, easily produce damagedly in the whipping process, this has not only increased self water absorption rate of haydite, but also has reduced the product heat-insulating property.Therefore, the existing method for preparing haydite aerated concrete or not ideal enough.

Summary of the invention

The purpose of this utility model is: a kind of simple in structure, easy construction is provided and can cause that haydite damages, the preparation facilities of the building block of good product quality, to overcome the deficiencies in the prior art.

The utility model is achieved in that the preparation facilities of a kind of building block of the present utility model is: this device is comprised of die trial and screen, and die trial is the barrel shape structure, and the horizontal cross sectional geometry of the die trial inner chamber of this barrel shape structure is polygon or circle; The shape of deleting plate is identical with the horizontal cross sectional geometry of die trial inner chamber, and deletes plate and can flatly cover in the inner chamber of die trial, is provided with through hole deleting plate.

The horizontal cross sectional geometry of the die trial inner chamber of above-mentioned barrel shape structure is regular polygon.

The diameter of the through hole of screen is 4mm～8 mm.

, delete the edge of plate and the clearance distance between the die trial internal chamber wall and be not more than 3mm when deleting in the inner chamber that plate level ground lid enters die trial above-mentioned.

Owing to adopted technique scheme, the utility model is for existing problem and difficult point in the prior art, by using screen restriction haydite aggregate come-up, then make slip through the slight space that is filled between the haydite of shaking, forming ceramsite material is evenly distributed in the air entrained concrete, simultaneously, the utility model has been abandoned traditional mode that ceramsite material and air entrained concrete slip are stirred together fully, the utility model can guarantee reliably that haydite can be not damaged, thereby has effectively solved existing haydite skewness in the prior art, the haydite badly broken, product quality is undesirable, the difficult problem such as unstable.So, the utility model compared with prior art, the utility model not only has can not cause that haydite damages, the advantage of good product quality, but also has the advantages such as simple in structure, easy construction, constant product quality.

The specific embodiment

Below, in conjunction with the accompanying drawings and embodiments the utility model is further described.

Embodiment of the present utility model: the utility model is constructed according to following a kind of method for preparing haydite aerated concrete block, the used haydite 3 of the method is haydite finished product of the prior art, the method is to be that the haydite 3 of 10～20mm is put into die trial 1 natural packing with particle diameter, then after haydite 3 covers the screen 2 that is provided with through hole 2.1 (as shown in Figure 1), the air entrained concrete slip 4 of making is poured in the die trial 1, air entrained concrete slip 4 will pass in the space that is filled in 3 of haydites behind the through hole 2.1 of screen 2 (as shown in Figure 2) like this, all flow through the through hole 2.1 of screen 2 when air entrained concrete slip 4 after, it is removable screen 2, then treat in a traditional way that air entrained concrete slip 4 is by getting angry, quiet stopping, can in die trial 1, prepare the uniform haydite aerated concrete block 5(of material after the maintenance as shown in Figure 3) product, after this product poured out die trial 1, die trial 1 can be used as again produced the next group product and uses; Its maintenance method can adopt steam press maintenance of the prior art, steam curing or alkali to excite the modes such as maintenance; Can evenly pass through glibly the through hole 2.1 of screen 2 for slip, after pouring into the air entrained concrete slip 4 of making in the die trial 1, preferably die trial 1 is put on traditional jarring machine or by manual mode slight vibrations are carried out in die trial, be filled in the space of 3 of haydites after making air entrained concrete slip 4 can pass equably the through hole 2.1 of screen 2; Its air entrained concrete slip 4 can adopt air entrained concrete slip of the prior art, but preferably adopt by cement, lime, gypsum, mineral admixture, air entraining agent, initiate agent, the air entrained concrete slip 4 that alkali-activator raw material and water mix and blend are prepared from, during making, with each raw material proportioning by weight be: 5～15 parts of cement, 10～15 parts in lime, 3～5 parts in gypsum, 65～82 parts of mineral admixtures, foaming agent is cement, lime, 4/1000ths～8 of gypsum and mineral admixture solid powder gross weight, air entraining agent is cement, lime, 5/1000ths～8 of gypsum and mineral admixture solid powder gross weight, alkali-activator is cement, lime, 5/1000ths of gypsum and mineral admixture solid powder gross weight, the weight of water and cement, lime, the ratio of gypsum and mineral admixture solid powder gross weight is 0.35:1～0.45:1; Its mineral admixture is to produce the flyash as waste residue, slag powders or the phosphorus slag powder that produces in the prior art, or the mixture that mixes by any weight portion proportioning for flyash, slag powders, these three kinds of raw materials of phosphorus slag powder, its slag powders is the mineral powders such as iron, copper, lead, zinc, aluminium, antimony, alum or silicon that produce during the mine produces; In haydite aerated concrete block 5 products that adopt the said method making to obtain, contain 0.3～0.4m in every cubic metre ³Haydite, and the use amount of the air entrained concrete slip of its haydite aerated concrete block of every cubic metre 5 products is 450～800kg/m ³
