Abstract

PURPOSE:To enable mud to be prepared successively and efficiently by providing, in turn from the inlet side and outlet side of a case, rod-shaped paddles, winged paddles, and screw feeders on a rotating shaft 5 mounted in the case formed in a tapered shape. CONSTITUTION:The viscous soil inputted into a case 1 from a supplying hole 2 is crushed in its clods at the rod-shaped handle mounted part 7 of rotating shafts 5, and becomes a mud state mixed with grains, and then kneaded at a winged paddle mounted part 9 and becomes a mud state without grains, and further ground at a screw feeder mounted part 11 and then discharged successively from a discharge hole 4, thus a fine and uniform mud can be obtained. And, should water addition be performed at the stage of crushing the clods of the viscous soil, high density slurry-stated mud can be prepared. In this instance, the case 1 is formed into a tapered shape and slightly slanted into a counter grade, thereby performing the grinding of mud by the screw feeder mounted part 11 and the successive discharge per constant quantity effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention pertains) The present invention relates to an apparatus for making clay mud (hereinafter referred to as mud).

(Problem to be solved by the invention and its characteristics) In recent years, construction materials have been developed that are lightweight, highly fluid, and have good workability, such as clayey soil, cement-based solidified materials, foamed materials, and water-resistant construction materials. It is increasingly being used for filling cavities that occur in building foundations, backfilling, and embanking.

An object of the present invention is to provide an apparatus that can continuously and efficiently produce mud, which is the base material of the construction material, and the structural features thereof are described in the claims. As I said.

(Explanation with drawings) In the drawings showing an embodiment of the present invention, 1 is a horizontally elongated box body, and one end of the box body has a supply port 2 of Kanto loam clay which opens upward at the entrance side of one end, and is connected to an appropriate water source. A certain water injection facility 3 is provided from the pipeline, and a soil discharge port 4 that opens downward is provided on the exit side of the other end.

The height of the box body 1 gradually decreases from the entrance side to the exit side, and is tapered.

Four rotating shafts 5 extending in the length direction are mounted inside the box 1, and rod-shaped paddles (■-shaped stirring blades) 6 are attached to these rotating shafts 5 in order from the inlet side to the outlet side. A rod-shaped paddle mounting part 7 to which a bladed paddle (T-shaped stirring blade) 8 is mounted, a winged paddle mounting part 9 to which a winged paddle (T-shaped stirring blade) 8 is mounted, and a screw feeder mounting part 1l to which a screw feeder (screw-shaped blade) 10 is mounted are provided. There is.

The box body 1 includes a drive motor 12 for the rotating shaft 5 and a deceleration mechanism part l3.
It is also placed on the base 14, and this base l
4 is installed on the frame 15 with a slight inclination from one end to the other end (see FIG. 3).

It is preferable that the inclination of the base l4, that is, the inclination of the box body 1, can be finely adjusted.
An inclination adjustment device l6 using a screw mechanism is provided at the other end.

When no water is added, the clay soil poured into the box body 1 from the supply port 2 is crushed by the rod-shaped paddle attachment part 7 of the rotating shaft 5, and becomes mud-like with crushed pieces (small lumps). It is kneaded in the paddle attachment part 9 and becomes a smooth slurry.
The slurry is further ground in the screw feeder mounting part 11 and continuously discharged in fixed quantities from the discharge port 4 to obtain fine and uniform mud.

Moreover, if water is added from the water injection equipment 3 at the stage of crushing the clay lumps, highly concentrated slurry-like mud can be made in the same way.

In any of these cases, the box body 1 has a tapered shape and is slightly sloped from the inlet side to the outlet side, so that mud stagnates on the outlet side of the box body 1. Since a blockage phenomenon occurs, the screw feeder mounting part 11
The grinding of mud and the continuous discharge in fixed quantities are effectively carried out.

In order to make the box body 1 tapered, the height is changed in the illustrated embodiment, but the width may also be changed; in this case,
It is also preferable that the interval between the rotating shafts 5 is gradually reduced from the inlet side to the outlet side.

In addition, if the inclination of the box 1 can be finely adjusted (usually in the range of +2° to +5°), the inclination of the box 1 can be adjusted to the optimum in accordance with changes in the properties of the clay soil, water content ratio, etc. It is convenient because it can be set.

(Effects of the Invention) Since the present invention is as described above, in the apparatus of claim 1, it is possible to continuously and efficiently produce mud suitable as a base material for the above-mentioned construction materials, and In addition, the apparatus according to claim 2 has the advantage of being able to respond to changes in the properties of clay soil, water content ratio, etc.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention, in which Fig. 1 is a partially cutaway plan view, Fig. 2 is a side view showing the inside of the box, and Fig. 3 is a side view showing the inside of the box. FIG. 3 is a side view showing the installed state of the base.

Claims (2)

[Claims] (1) A horizontally long box that is tapered from the entrance side where the cohesive soil supply port and water injection equipment are installed to the exit side where the soil discharge port is installed, and is slightly inclined with a reverse slope.
