JPS6157226A - Shaking type mixer - Google Patents

Abstract

PURPOSE:To remove air bubbles adhered to the periphery of a material or air involved in internal gaps, by arranging a rotary drive apparatus, which applies mixing motion different from the shaking motion of a bottom part to a material during mixing, to a shaking mixer. CONSTITUTION:After predetermined weighed materials such as cement, a fine aggregate or water were thrown in a mixing container C, an upper lid 26 is closed by bolts 30 to hermetically close said container C. When a hydraulic motor 12 is subsequently rotated, a shaking plate 16 generates shaking motion thrugh a shaking part B and the materials in the mixing container C are diffused and mixed. Succeedingly, when a vacuum pump V is operated to evacuate the mixing container C and, at the same time, the sucking is performed from the suction socket 33 in the side of a reversal frame, vacuum advances outside and inside the mixing container C. Because air between aggregates is sucked in the mixing container C, even if fluffy carbon fibers are present, the materials are equally dispersed without generating small lumps or pillings.

Description

[Detailed Description of the Invention] Fields of Application of Vegetables> The present invention is directed to an oscillating mixer that mixes by imparting lateral motion to the bottom of a flexible material container.

Composite concrete technology has been developed to increase the sag of cement-based concrete and to add kVA of dense materials such as carbon fiber and glass fiber to achieve high bending and tensile strength. There is.

8 to 17 microns due to the virtue of a hypoaxial fiber such as carbon fiber,
When the specific electric current is between 1.2 and 1.9, and when mixed with cement and water, the fiber material quickly spreads and becomes ball-shaped, forming water droplets on cement particles, rut fibers, and fine aggregate. ? Air bubbles were attached, making it difficult to disperse the fibers. By sealing the inside of the Nananotari mixing container and mixing under vacuum conditions, we can remove all contamination from fibers and lamps, and also remove the contamination from fibers and other substances that spread between the lamps. An empty mixer was used to stir the bubbles.

The purpose of the present invention is to remove air cores that adhere to the periphery of the material and air that permeates into internal gaps by adding wax fibers or water, and thereby By increasing the surface area of cement through redispersion, the weight of cement pest can be increased and the amount of cement used for use can be reduced.

Measures to solve the problems〉 In order to degas the air bubbles and surface air mixed into the circular part of the material being mixed, an agitator etc. is installed from the outside in the mixer seeding part.
The ball method is equipped with an agitator mechanism that finely pulverizes the small lumps of the material during mixing, degassing the air bubbles and expanding the chemical reaction to increase the temperature of the mixture. Dynamic vacuum mixer equipment is used.

In order to remove air, surface water, and air bubbles that may be present during mixing using an agitator or the like, a rigid container is equipped with a rotating shaft and is flexible. The materials t'p are dispersed and mixed in both directions by a freely movable rocking plate.
+ The vacuum pump is operated differentially when the mixture is expanded by dispersion, and at the same time, the desired air bubbles are formed around the material. It is easy to suction and remove the heart and spirit, which promotes uniform dispersion of the mixture.
By eliminating the air gaps that exist between materials and fibers, it is possible to shorten the acid formation time in the forming and filling process, increase the filling rate, promote ``x degree'', and reduce the amount of cement used per unit. Easy to form rigid composite concrete products/b

<Implementation> Figure 1 is an overall view of the mixer of the present invention, in which a reversing frame 2 is supported by an inverting shaft 3 on a fixed frame 1 so as to be vertically inverted. A tin rocket 5 is fixed to one of the spindles. A torque actuator that can rotate 180 degrees is attached to one side of the fixed frame 1 (on the side of the sprocket 5), a tin rocket 8 is attached to the tip of the shaft, and a chain 6 wound around the tin rocket 5 is connected. are doing.

Therefore, when the torque actuator is differentially moved, the inversion frame 2 is inverted vertically. A mixing container C whose parts are integrated by a connecting annular band 24 is attached to an inversion frame hermetically sealed by a drive mounting plate 20 and a mixing container fixing plate 22.

The swing plate 16 and the swing plate 7V-A1 of the flexible portion IO
7 is turning drive MQul 3. A swinging eB equipped with a rotating arm 15 having a rotating shaft 14 degrees is fixedly mounted with a 18 degrees 19 degrees bolt.

When the hydraulic motor 12 is operated differentially, the swing part B causes the flexible part 10 to swing, thereby accelerating the mixed material in the mixing container C and scattering it in a random direction by changing the direction of the mixed material M. Diffusion mix.

At this time, since the peripheral wall of the mixing container C is equipped with an agitator A that finely pulverizes the mixture, lumps and small lumps of the mixture in the container are loosened by the U rotation of the blade 42 of the agitator, and when crushed, internal air bubbles are formed. is also degassed.

The upper lid 26 with the sealing seal 34 attached to the upper open part of the mixing container C is completely sealed with attachment holes 30 attached to both sides of the steel upper frame 25.

When the vacuum pump V is oscillated to start suction while mixing the inside of this sealed container by interlocking oscillation, the pressure inside the mixing container is gradually reduced. Under 0 reduced pressure conditions, air intervening between the mixed materials put in is mixed. is sucked and the inside of the container becomes a vacuum state, so that the mixed aggregate is dispersed and the mixing action is accelerated at an accelerated rate.

In this case, as the vacuum inside the mixing container C progresses, the rubber part of the town@ section will develop depressions in some parts due to the suction pressure, which will adversely affect the dispersion of the material in the container, so the inverted frame part should be sealed. By suctioning and reducing the pressure from both the 33° suction port and the 33° suction port, it is possible to perform stable rocking motion under the same vacuum conditions on the inside and outside of the mixing container.0 Use of the mixing device described above The method is as follows.

First, all predetermined measured materials such as cement, fine aggregate, coarse aggregate, carbon fiber, and water are put into a mixing container, and then the upper lid 26 is sealed with the bold 30.

Next, when the mixing operation valve 39 is differentially operated and the hydraulic motor 12 attached to the lower end of the reversing frame is rotated, the swinging plate 16 is caused to swing in conjunction with the swinging portion B'Th. Each material is mixed by diffusion.

Next, the vacuum pump V is operated differentially to cover the inside of the mixing container C with the upper lid 2.
When the pressure is reduced through the suction socket 32t of No. 6 and at the same time suction is also taken from the suction socket 33 on the reversing frame side, a vacuum state develops inside and outside the mixing container, and since each suction socket is connected to the vacuum tank 35, the same 0 displayed on the vacuum tank gauge 36 under the pressure condition of 0 Since the air between the aggregates is sucked in the mixing container, each material is evenly distributed without the generation of small lumps or lumps like in the past, even with cotton-like carbon fiber. In addition, air bubbles present inside the fine aggregate are released into the vacuum mixed species due to the operation of the agitator A, but are immediately sucked.

In this case, if suction is started when the mixing container is completely dry with no moisture, fine powder particles such as cement will be sucked into the vacuum tank before being mixed with the aggregate, so suction will not be effective. When starting, it is desirable to start the vacuum pump after the mixed water is in a wet state.
Since the f-touch has been cut and mixing has been completed, open the top lid suction hole 3.
21 Socket 3 for suction insertion from inverted frame suction port 33
1, then remove the top cover to discharge the material, and then operate the reversing operation valve 38, the torque actuator is differentially activated, and the mixing container is reversed via the chain 6t to exit from the upper opening. The material is discharged into the material supply hopper 40.

This discharged material is moved to the next forming and filling process, where it is vibrated and pressure-formed. When the next mixing is to be performed, the reversing operation valve 381 is operated again, and the upper opening part is rotated in the normal direction as shown in FIG. Return to position.

Next, put in the various materials that have been softened and weighed, put the top lid on, and then connect the vacuum suction socket 31 to each suction port 32.
33, and then operate the driving operation valve 39 to repeat the same procedure as described above to mix.0 An example of mixing concrete containing carbon fibers using a vacuum mixer has been described. If necessary, by replacing the Mixing Zen 11 with additional spiral rods and rotating blades, shear mixing and convection mixing can be used together, and it is possible to easily perform mixing under either atmospheric pressure or suction vacuum. bl.

<Effects of the Invention> The present invention finely pulverizes the clay part and fibrous pole-shaped small lumps intervening in the mixture by applying an interlocking action different from the stirring interlocking action inside the mixing container from the outside using an agitator or the like. This enlarges the specific surface at which is favorable for the curing reaction.

This increases the amount of cement paste, reduces the amount of air bubbles in the mixture, and at the same time increases fluidity, making it possible to obtain a mixture with even strength. Air bubbles mixed into the internal pores of fine aggregate, which are difficult to remove under atmospheric pressure and have a great effect on mortar, can also be degassed, and air bubbles can be removed during mixing, such as with brittle aggregates with extremely different specific gravities. By mixing easily mixed materials in a vacuum, the mixture can be evenly dispersed and easily dispersed. This reduces the time in the molding and filling process and reduces the vibration force, preventing noise and sealing conditions. In addition to improving the molding operation rate, such as preventing the generation of dust due to mixing, the work environment has also been improved, and the technological and economic effects are extremely large.
