Description

The production equipment of concrete admixture

Technical field

The utility model relates to the chemical industry equipment field, relates in particular to a kind of production equipment of concrete admixture.

Background technology

In Chemicals were produced, frothing can appear in whipping process, and this foam is a large amount of gatherings of bubble, and there are many harm in these foams.1) throughput is limited greatly: various reactor equipment, and in order to prevent the appearance of foam, the loss that prevents from overflowing, batch charging coefficient will be had a greatly reduced quality.2) cause the waste of raw material and product: foam can cause useful or valuable raw material to lose because overflowing.3) prolonged reaction time: include gas, liquid in the chemical reaction product, foam can cause gas hold-up, has prolonged reaction time, unnecessarily the power that consumed more.4) influence product quality: the delay of bubble, cause occurring many holes on the finished product, cause quality product seriously to descend.5) be unfavorable for accurate metering: in the commercial run, the existence of foam, disturb the measurement of liquid level meter accurate, cause and measure error, because the existence of foam makes fluid density take place than great fluctuation process, still absorbing tower liquid-level virtual height often can also induce reaction in the liquid, cause the operation overbalance, even have an accident.

In the concrete admixture production process, the chemical reaction of raw material and the stirring of machine can be introduced a large amount of bubbles, and this bubble merges the formation foam easily, and very unstable, very easily broken bubble, and the slump-loss of broken bubble back concrete mix is very big; Remaining bubble forms than macroscopic void in the concrete hardening thing, reduces concrete hardening thing intensity greatly, all is harmful to very much for the serviceability of concrete mix and the mechanical property of concrete hardening thing.In the traditional production device, in reactor, add silicone based defoamer usually and carry out froth breaking.But the defoamer price is higher, has both increased production cost, impurity can be introduced the admixture mother liquor again, thereby influences the problem of quality product.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of production equipment of concrete admixture, can reduce the generation of bubble under the situation of not using defoamer, reduces production costs; Can avoid introducing impurity, guarantee the quality of production of product.

The technical scheme that the utility model adopts is: the production equipment that a kind of concrete admixture is provided, comprise enamel reaction still, be installed on the motor at enamel reaction still top, fixedly connected with the rotating shaft of motor and stretch to the stir shaft of enamel reaction still bottom and be fixed in agitating vane on the stir shaft, the inner side-wall of described enamel reaction still is provided with except alveolar layer, described except alveolar layer be porous material.

Wherein, the described alveolar layer that removes is around being distributed in all sides of described enamel reaction still inwall.

Wherein, described porous material is porous ceramics or foamed metal.

Wherein, also comprise the tempilstick that is installed on described enamel reaction still top, the temperature sense end of described tempilstick stretches in the enamel reaction still and to the bottom of enamel reaction still and extends.

Useful technique effect of the present utility model is: be different from the production equipment of existing concrete admixture, usually in reactor, add silicone based defoamer and carry out froth breaking, because the defoamer price is higher, has both increased production cost, impurity can be introduced the problem of admixture mother liquor again.The utility model provides a kind of production equipment of concrete admixture, mainly comprise enamel reaction still and be built in the enamel reaction still inner side-wall except alveolar layer.During work, the mother liquor of the concrete admixture in the enamel reaction still contacts with removing alveolar layer, and the bubble that produces in the mother liquor becomes big by porous material except alveolar layer constantly merges, and can accelerate brokenly bubble.This froth breaking layer can be saved the use of defoamer, reduces production costs, and avoids introducing impurity.The utility model is simple in structure, can reuse economic environmental protection.

Label declaration:

The 1-enamel reaction still, the 2-tempilstick, the 3-motor, the 4-stir shaft, the 5-agitating vane, 6-is except alveolar layer, 7-discharge port, 8-dog-house.

Embodiment

By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1 and Fig. 2, the utility model provides a kind of production equipment of concrete admixture, comprises enamel reaction still 1, is installed on the motor 3 at enamel reaction still 1 top, fixedlys connected with the rotating shaft of motor 3 and stretches to the stir shaft of enamel reaction still 1 bottom and be fixed in agitating vane 5 on the stir shaft 4.The top of described enamel reaction still 1 is provided with dog-house 8, and the outer side wall of described enamel reaction still 1 is provided with discharge port 7 near the position bottom it.The inner side-wall of described enamel reaction still 1 is provided with except alveolar layer 6, described except alveolar layer 6 be porous material.

During work, be injected into the enamel reaction still 1 from the mother liquor of dog-house 8 with concrete admixture, mother liquor with contact except the porous material in the alveolar layer 6, the bubble that produces in the mother liquor becomes big by vesicular structure except alveolar layer 6 constantly merges, and at stir shaft 4 and be fixed in the growth that to accelerate bubble under the stirring action of paddle of agitating vane 5, and then breaking bubble fast, the elementary product that obtains behind chemical reaction is derived from discharge port 7.

In a specific embodiment, above-mentioned removes alveolar layer 6 around being distributed in all sides of described enamel reaction still 1 inwall.This kind structure can increase except the contact area of alveolar layer 6 with the concrete admixture mother liquor, thereby increase de-bubble efficient, should be noted that except said structure in order to reduce the area except alveolar layer 6, the scheme that is distributed in the inwall of enamel reaction still 1 except alveolar layer 6 discontinuously also is feasible.Preferably, above-mentioned porous material is inorganic materials such as porous ceramics or foamed metal.In the preferred scheme, also comprise the tempilstick 2 that is installed on described enamel reaction still 1 top, the temperature sense end of described tempilstick 2 stretches into enamel reaction still 1 and extends to the bottom of enamel reaction still 1.Tempilstick 2 is for detection of the raw material reaction temperature in the enamel reaction still 1.
