Description of the Related Art Conventionally, as a continuous kneading apparatus for a powdery hydraulic material, a kneading mechanism of a powdery hydraulic material and water and a power source for driving a pressure pump are arranged on substantially the same straight line. An apparatus for continuously kneading and pressure-feeding a powdery hydraulic material has been proposed (Japanese Patent Laid-Open No. 3-121815).
The mixing shaft of the kneading mechanism of this continuous kneading device is
A shaft that is rotated by a power source and a kneading paddle are fixed by means such as welding, and if the weight ratio of water to the powdery hydraulic material is about 20% by weight, uniform kneading is possible. However, if the weight ratio of water to the powdery hydraulic material is to be kneaded at 50% by weight or more, kneaded balls are formed in the material discharged from the kneading device,
There was a problem that uniform kneading was not possible. In particular, when the powdery hydraulic material is to be kneaded as a milk-like material, this phenomenon is remarkable, and continuous kneading of the powdery hydraulic material has been considered impossible.

行おうとする際、運転が不可能となる問題があった。In recent years, there has been a movement for a continuous kneading apparatus for a powdery hydraulic material having rapid hardening.
When trying to knead the powdered hydraulic material having rapid hardening by the continuous kneading device, the powdery hydraulic material that is not sufficiently kneaded adheres to the rotating shaft, paddle portion, and / or mixing cylinder near the water supply port. However, the hardening growth in a short time causes a problem that the supply amount of the powdery hydraulic material having rapid hardening from the screw feeder gradually decreases, and kneading cannot be performed at a predetermined ratio. Further, in the case where the mixing cylinder is made horizontal by removing the pressure feed pump of the kneading apparatus, when the weight ratio of water to the powdery hydraulic material is about 20% by weight, powder remains in the hopper in addition to the above-mentioned problems. If kneading is interrupted in a mixed state, the unmixed powdered hydraulic material remains and hardens, or the kneading water soaks into the screw or hopper side and attempts to perform kneading again.

棄せねばならず不経済であることなどの課題があった。When a batch-type kneading apparatus is used, homogeneous kneading can be performed even with a powdery hydraulic material having a water content of 50% by weight or more with respect to the powdery hydraulic material. The work is complicated due to the need to weigh the materials, and the kneading amount for one batch is fixed.
When a large amount of kneaded material remains when the operation is completed, it must be discarded, which is uneconomical.

Reference numeral 1 denotes a power source, which is rotated to transmit power to the rotary shaft 3 by the power transmission device 2 to rotate the stirring blades 4 attached to the rotary shaft 3. Describing the supply of the material, the powdery hard material 9 supplied to the hopper 8
By the fixed amount supply device 11 driven by the power source 10,
The material is supplied from the material supply port 12 to the vertical material supply cylinder 7.
The powdered hydraulic material 9 supplied to the vertical material supply cylinder 7 is
It is supplied to the vertical mixing cylinder 6 by natural fall. On the other hand, kneading water is supplied at a constant rate from a water supply pipe 5 provided on the side of the vertical mixing cylinder 6. The powdered hydraulic material 9 and the kneading water are kneaded by the rotation of the stirring blade 4, and are discharged through a kneaded material discharge port 13 and a discharge pipe 14 provided at a lower portion of the side of the vertical mixing cylinder 6.

くくなり、所定の濃度の混練ができなくなる。Here, it is preferable that the rising height of the tip of the discharge pipe 14 be 100 mm or more. Launch height is 1
If it is smaller than 00 mm, the amount of stay is small and the mixing effect due to stay is small, and the mixture is discharged with the kneaded balls left in the mixture. Further, the rising height of the discharge pipe 14 can be increased to a level at which the mixing water surface does not wet the wall surface of the vertical material supply cylinder 7. When the wall surface of the vertical material supply cylinder 7 gets wet with the kneading water or the kneaded material, the powdery hydraulic material adheres to the wall surface of the vertical material supply cylinder 7 and becomes difficult to be supplied to the vertical mixing cylinder 6 and has a predetermined concentration. Can no longer be kneaded.

If the rotation speed is less than 200 rpm, the stirring effect is small, and even if the rising height of the discharge pipe 14 is sufficient, the shearing effect cannot be obtained and uniform kneading cannot be performed, so that kneaded balls remain in the kneaded material.

も同様に試験を行った。測定結果を表１に示す。EXPERIMENTAL EXAMPLE 1 Using the continuous kneading apparatus shown in FIG. 1, a fixed amount of powdery hydraulic material was supplied near the axis of the vertical material supply cylinder 7, and a turbine blade type stirring blade was provided at the bottom of the vertical mixing cylinder 6. And one drain pipe
40 mm was started, and kneading water was mixed with 100 parts by weight of a powdery hydraulic material composed of 50 parts by weight of calcium aluminate and 50 parts by weight of gypsum, which were rapidly hardened components, to form a powdery hydraulic material 100
The kneading agent was added in an amount of 220 parts by weight based on 100 parts by weight of the powdery hydraulic material, and the mixture was continuously kneaded. In addition, the coagulation time adjusting agent was previously dissolved in the kneading water, and this was supplied to the continuous kneading device in a constant amount. The rotation speed of the stirring blade was 500 rpm. The diameter of the vertical material supply cylinder was 165 mm, the diameter of the vertical mixing cylinder was 216 mm, and the height of the vertical mixing cylinder was 400 mm. Immediately after the start of continuous kneading and 30 minutes later, the kneaded material is sampled from the discharge pipe 14, and the kneaded material is passed through a 300 μm sieve to check whether the kneaded material is homogeneously kneaded, and the presence or absence of residue on the sieve is visually observed. Observation was made as x when there was a residue, and as x when there was no residue. Further, in order to determine whether the powdery hydraulic material is supplied in a fixed amount, the density of the kneaded material immediately after the start of kneading and after 30 minutes has elapsed is measured, and the density is 0.2 g / cm 3.
A sample having the above-mentioned decrease was evaluated as x, and the others were evaluated as ○. For comparison, the same test was performed on the conventional continuous kneading apparatus shown in FIGS. 2 and 3. Table 1 shows the measurement results.

る。As described above, according to the present invention, the following effects can be obtained. By using the continuous kneading apparatus of the present invention, the powdery hydraulic material and water can be kneaded continuously. In particular, homogeneous kneading becomes possible in the range of 50 parts by weight or more of the mixing water with respect to 100 parts by weight of the powdery hydraulic material. It is also effective for kneading milk-like materials that do not contain fine aggregate or coarse aggregate. This has the effect of reducing the complexity and kneading loss of conventionally used batch mixers.
