Abstract

The utility model discloses a stirring kettle which comprises a motor (1), a shaft sleeve (2), a stirring shaft (3), an S-shaped stirrer (4), a heating sleeve (5), a discharge opening (6), a charging opening (7) and a kettle body (8), wherein the axial projection length of the stirrer (4) is 0.5-2 times of the height of the stirring shaft (3); the distance between the S-shaped bottom of the stirrer (4) and the discharge opening (6) is 10-30 cm. The S-shaped stirrer adopted by the utility model can provide the flow state in different levels, so as to increase the probability of contact of mixed material interphase interfaces and strengthen the interphase mass transfer effect, and in the process, air bubbles are continuously squeezed and released out, and meanwhile, gas is rapidly taken away under the action of vacuum-pumping, so that the purpose of removing the air bubbles is achieved; due to the adopted square cross section of the stirrer, more mixed materials can be driven to participate in flow, and meanwhile, due to the viscosity of the mixed materials, more mixed materials around can be driven to participate in rotation flow, so that the interface updating speed is accelerated, and the exhaust velocity is improved.

Description

Stirred tank

Technical field

The utility model relates to a kind of stirred tank, is specifically related to the stirred tank used in a kind of artificial stone manufacture process, belongs to the artificial stone production technical field.

Background technology

Artificial stone is to be fired into pasty state after the powders such as quartz sand, feldspar powder, barite, prodan, sodium nitrate, borax, soda ash, zinc oxide are mixed by a certain percentage, then casting, again moulding material is carried out being prepared from after annealing in process, wherein in sintering procedure, need the bubble in batch mixing is carried out to the vacuum eliminating, if get rid of badly, the quality of artificial stone will directly be affected.The method of getting rid of bubble is that the batch mixing in still is fully stirred, vacuumized processing simultaneously, because batch mixing density is large, viscosity is high, so having relatively high expectations to agitator, current stirred tank polygamy is put linear pattern or foliaceous agitator, low for linear pattern agitator fluid line speed, the fluid motion state is single, stirring efficiency is low, easily leave dead angle for volume larger or non-circular stirred tank, make to mix inhomogeneous, for the foliaceous agitator, due to blade and the fluid contact area large, flow velocity is high, easily form the whitewashing phenomenon, also be unfavorable for the mixing of artificial stone batch mixing.

Summary of the invention

The problem existed for above-mentioned prior art, the utility model provides a kind of stirred tank, and this stirred tank stirs, and can produce different fluid flow states from different levels, the bubble of concealing in batch mixing inside is exposed as far as possible, in order to better exclude.

To achieve these goals, the technical scheme that the utility model adopts is, a kind of stirred tank, comprise motor, axle sleeve, shaft, agitator, heating jacket, discharging opening, charge door, kettle, wherein said shaft and agitator are fixed together, and described agitator is the S type, and its cross section is square.

Described shaft upper end is straight rotating shaft, and lower end is S type agitator, and the projected length of described S type agitator on axis is 0.5～2 times of shaft height, 10～30 centimetres of the distance from bottom discharging openings of described S type agitator.

Described agitator cross section square is a kind of in rectangle or square.

Further, when the cross section of described agitator is rectangle, its length-width ratio is between 1～2, and length direction is perpendicular to the straight line at shaft place, and can be included in the plane by the shaft place.

With the agitator that traditional production artificial stone is used, compare, the S type agitator that the utility model adopts can provide the flowing velocity of different levels, produce the flow regime of different levels, thereby form different velocity gradients, this change has increased the probability of batch mixing interphase interface contact, has strengthened the effect of interphase mass transfer, and this strengthening process makes bubble constantly be extruded and separate out, taken away rapidly under the effect vacuumized, thereby reached the purpose of getting rid of bubble simultaneously; The square-section that this agitator adopts in addition can drive more batch mixing and participate in flowing, and the viscosity effect due to batch mixing simultaneously also can drive more batch mixing participation rotational flow on every side, thereby has accelerated the speed that interface is upgraded, and makes exhaust efficiency higher.

The accompanying drawing explanation

Fig. 1 is the structural representation of the utility model stirred tank.

In figure: 1. motor, 2. axle sleeve, 3. stir and take out, 4. agitator, 5. heating jacket, 6. discharging opening, 7. charge door, 8. kettle.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

A kind of stirred tank, as shown in Figure 1, comprise motor 1, axle sleeve 2, shaft 3, agitator 4, heating jacket 5, discharging opening 6, charge door 7, kettle 8, wherein said shaft 3 is fixed together with agitator 4, described agitator 4 is the S type, its cross section is square, the projected length of described S type agitator 4 on axis is 0.5～2 times of shaft 3 height, the distance of discharging opening 6 is arrived between 10～30 centimetres in S type bottom, when rotating, the too little agitator 4 of this distance easily touches kettle 8 bottoms, if this distance is too high batch mixings kettle 8 bottoms will can not get sufficient stirring, affect mixed effect, the cross section of agitator 4 is a kind of in rectangle or square, when being rectangle, its length-width ratio is between 1～2, if this length-width ratio is too large, the density due to the artificial stone batch mixing is larger, viscosity is higher, the easy flexural deformation of agitator 4 in whipping process, even fracture, if too little do not have the effect that is uniformly mixed preferably, and, as rectangular stirring cross section, its length direction will be perpendicular to the straight line at shaft place, and can be included in the plane by shaft, using larger cross section goes stir mixing just can reach mixing effect preferably.
