Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for promoting vaporization of liquids or liquid-containing materials used for drying and deaeration of powder and granular materials, mixed drying, water removal from industrial wastewater, etc. This invention relates to a method for adjusting the slump value of hydraulic curing raw materials.

Generally, in order to vaporize a liquid or dry a liquid-containing substance, a heating method and a reduced pressure method are employed.

However, the heating method requires a large amount of thermal energy, and the depressurization method has a slow vaporization rate (it has the disadvantage that depressurization must be continued for a long time).

One of the objects of the invention is to quickly and economically vaporize liquids or liquid-containing substances.

In addition, conventional production of hydraulic hardening raw materials such as ready-mixed concrete and ready-mixed mortar involves simply mixing hydraulic substances such as cement, fine aggregates such as sand, water, or even coarse aggregates such as gravel in a fixed mixing ratio. The water content and water absorption rate differ when fine aggregate and coarse aggregate are used, so even if they are mixed at the same mixing ratio, the slump value will differ and the strength will vary greatly. There was a drawback.

Another object of the present invention is to provide a method for adjusting the slump of a hydraulic hardening raw material using the vaporization promotion method described above.

The vaporization promotion method of the present invention, which meets the above objectives, is carried out by pumping gas from one side of the hermetic container and exhausting it from the other side, or by suctioning gas from one side and introducing it from the other side. The slump value adjustment method is characterized by creating a gas flow and causing the gas flow to act on the liquid or liquid-containing material in the sealed container to promote vaporization of the liquid. A gas flow is created in the sealed container by discharging from the other side or suctioning gas from one side and introducing it from the other side, and the gas flow is slumped to a desired slump value of the crosstalk in the sealed container. It is characterized by acting on a hydraulic curing raw material with a large value to promote the vaporization of water and adjusting the slump value to a desired slump value.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The water vapor is cooled and becomes water, and the water is sent to the collection box 9. be captured. The gas-liquid separator 8 of the embodiment is equipped with a filter Qa that allows air to pass through but does not allow water vapor to pass through.

When seawater is poured into the upper container 12 in the closed container 1' from the liquid inlet pipe 4 provided at the upper part of the closed container 1', the seawater overflows into the upper container 12 and sequentially falls into the lower container, causing the seawater to flow into the container 12.12. ...The inside is filled with seawater.

The surplus seawater is then discharged from the surplus seawater discharge pipe 1 at the bottom of the sealed container 1'.
The valve 16 of No. 5 is opened to discharge the water to the outside.

Next, when the valves 6 and 16 are closed and the compressor 7 of the gas pressure pipe 2 is activated, the air moves in the direction of the arrow, and the air flow promotes the vaporization of seawater, and the humid air passes through the gas discharge pipe 3 and becomes a gas.

supply to. The flow plates 12', 12'... may be arranged horizontally, but they may also be arranged with an inclination as shown in Figure 5. In particular, the slope of the flow plates should be made smaller as it goes downward. If this is the case, it is also possible to drop the dried salt directly from the lowest falling plate and take it out. In the figure, numeral 17 is a plate material for creating an air flow in a fixed direction above the flow plate.In order to effectively flow down the salt on the lower flow plate, shake it on the flow plate;

The seawater impregnated in the water vaporizer 8 is vaporized and separated into air and water by the gas-liquid separator 8 through the gas discharge pipe 3, and the water is continuously collected in the collection box 9. Note that 20 is a water-impermeable pipe formed on the outer periphery of the porous cylindrical body 18. As shown in FIG. 7 and FIG. As shown in FIG. 9, a spiral porous cylinder 18' may be used instead. Further, as shown in FIG. 10, a porous cylindrical body 18'' having a plurality of protrusions 18''a formed inside may be used instead.

Further, the lower end of the gas pressure feeding pipe 2 may or may not be inserted into the seawater in the hollow portion of the porous cylinder. Further, instead of the porous cylinder, a fiber-based cylinder formed by gathering fibers into a cylinder or a paper thread cylinder can also be used. In other words, any type of material may be used as long as it causes capillary action. Alternatively, the cylindrical body may be moved up and down into seawater to sufficiently moisten it and promote vaporization by air flow.

The method for promoting the vaporization of seawater and the method for collecting water using a vaporization promoting device have been explained above, but if the purpose is not to collect water, the closed container does not necessarily need to be sealed; May be released into the atmosphere. In addition, the vaporization promoting device is not limited to promoting the vaporization of seawater, but can also be used to promote the vaporization of industrial wastewater such as waste liquid from plating chemical factories, human waste, etc.
It can be used to accelerate the vaporization of various liquids, and can also be used in conjunction with heating to promote vaporization. In addition to the gas-liquid separator using a filter, other conventional gas-liquid separators such as a gas-liquid separator using a cooling method can be used.

Next, a description will be given of the evaporation promoting dosage, which can be used not only for drying powders and granules, but also for drying damp clothing.

Fig. 1 shows a vaporization accelerator in which a gas pressure feeding pipe 2 is provided at the lower end of a closed container 19 whose lower part is shaped like a bowl, and a gas discharge pipe 3 is provided at the upper end. When the compressor 7 of the gas pressure feed pipe 2 is activated, the air flows toward the gas discharge pipe 3, creating an air flow, promoting the vaporization of the liquid contained in the powder, and humid air is released from the gas discharge pipe 3. As it is discharged, the powder is circulated and mixed in the direction of the arrow. Note that 2° is a lid that can be opened and closed, and the lid 20 is opened to introduce powder or the like into the closed container 19. 21 is a lid for discharging powder and the like. In addition, filters are attached to the attachment ports of the gas pressure feed pipe 2 and the gas discharge pipe 3, and can be used not only for drying powder and granules but also for drying clothes and the like.

When the motor 24 operates, the gear 25 rotates, and the teeth 23 formed on the outer periphery of the sealed container 23 rotate.

Incidentally, a protrusion 26 is formed on the inner wall of the closed container 23, so that the powder etc. placed in the container 23 can be thrown up. Open the opening/closing door (not shown) provided on the box 22 and the sealed container 23, put powder, etc. into the sealed container 23, close the opening/closing door, and operate the motor 24 to rotate the indoor container 23. The bodies etc. are thrown up by the protrusion 26 and dispersed. When a compressor (not shown) is operated and air is forced into the closed container 23 from the gas pressure feed pipe 2, the inside of the closed container 23 is A spiral air flow is generated from the gas pressure feeding pipe 2 toward the large number of small holes, which promotes vaporization of the liquid contained in the powder and the like, thereby drying the powder and the like. The humid air discharged from the small hole of the closed container 23 is discharged from the gas discharge pipe 3 provided in the box 22. Once the powder, etc. is dry, stop the operation of the motor and compressor, open the door and take out the powder, etc. It goes without saying that a gas-liquid separator may be provided in the gas discharge pipe 3 shown in Figures 1 and 12 to collect the liquid.

Furthermore, the closed container 23 shown in the twelfth figure does not necessarily have the protrusion 26.

Reference numeral 37' denotes a gas introduction pipe provided with a curl 38, which is provided opposite to the vacuum suction pipe 36' and communicated with the closed container 27'.

Next, a general method for treating hydraulic hardening raw materials using the above-mentioned vaporization accelerator E or E' will be explained by taking a cement-based hydraulic hardening raw material as an example. First, the discharge port opening/closing cover 34 or 34' is closed, and a prime mover such as a motor (not shown) is operated to rotate the stirring shaft 30 or 30'. Next, the input port opening/closing lid 32 or 32' is opened and cement and water, or sand or sand and gravel are added, and the materials are stirred and turned into hydraulic hardening raw materials. Next, the input opening/closing lid 32
Or, close the airtight container 27 or 27' by closing the valve 38 or 32' of the gas introduction pipe 37 or 37'.
8' is closed and a vacuum suction device (not shown) is activated, the air inside the closed container 27 or 27' is sucked into the vacuum suction pipe 3.
6 or 36' to reduce the pressure.

When θθm1Hjj is reached, the operation of the vacuum suction device is stopped and the valve 38 or 38' is opened.
The pressure inside the closed container 27 or 27' is restored to normal pressure, and the cement or even the sand or sand and gravel becomes sufficiently hydrated. If the mixing is continued further, the excess water that was injected into the sand and gravel will gradually seep out to the outside and mix well with the cement, and the alkaline content of the cement will be leached out, and the mixing will occur in the presence of water. It is activated and the adhesion becomes good. If the pressure is reduced and restored one or more times in addition to kneading, the alkali content of the cement will be eluted and activated in a short period of time, resulting in good adhesion. At this stage, the hydraulic hardening raw material may be taken out and hardened, but aggregates such as sand and gravel have different moisture content and water absorption depending on where they are collected, and even when mixed at a fixed water ratio, the slump value will vary. This causes variations in strength and cracks. Therefore, it is possible to adjust the slump value to a desired slump value, and if the final slump value is smaller than the desired slump value in the above processing method, the vaporization accelerator E or E' is equipped with an atomizer, and The desired slump value can be adjusted by mixing water into the hydraulic curing raw material inside.

Also, if the slump value is thicker than the desired slump value,
Open the valve 38 or 38' to operate the vacuum suction device, introduce outside air from the gas introduction pipe 3γ or 37', and enter the airtight container 27 or 27' from the gas introduction pipe 37 or 37' to the vacuum suction pipe 36 or 36'. The slump value can be adjusted to a desired slump value by generating an air flow in the opposite direction and causing the hydraulic curing raw material being kneaded to act on the air flow to promote water vaporization. As a result of this adjustment, a state is achieved in which the sand or gravel is sufficiently moist but water does not seep out. Therefore, excess water that causes hydration and breathing after forming does not seep out from the aggregate, and the cement is sufficiently activated and alkaline content is sufficiently eluted, resulting in good adhesion. Therefore, mortar and concrete with high strength and less splicing can be obtained.

In order to adjust the slump value of the hydraulic curing raw material to the desired slump value, it is necessary to check the slump value. In addition to being able to convert, it is also possible to convert the penetration resistance value when the rod is pushed into the slump value. More specifically, resistance values such as the torque value of the stirring shaft and the penetration resistance value of the rod at the slump value of the hydraulic curing raw material are stored in the microcomputer, and the above resistance values are converted into the slump value. It can be displayed. When adding water or steam to adjust the slump value to a desired slump value, the increase value of the slump value depending on the amount added is determined in advance by experiment or calculation, and this is stored in the microcomputer. The slump value can be adjusted to a desired slump value by adding a predetermined amount of water or steam. In addition, when adjusting the slump value to the desired slump value by applying an air flow to the hydraulic curing raw material to promote water vaporization, determine the decrease in slump value per time the air flow is applied by experimenting or calculating in advance. The desired slump value can be adjusted by determining the slump value, storing it in a microcomputer, and applying it to the air flow for a predetermined period of time. In addition, a control device is installed that drains water when the slump value is smaller than the desired slump value, and acts on the airflow when the slump value is larger than the desired slump value, and automatically adjusts the slump value to the desired slump value. The value can be adjusted.

For example, in a device in which the stirring rod of a commercially available viscosity measurement control device (such as the digital viscosity measurement control device manufactured by Ono Sokki Seisakusho Co., Ltd.) is replaced with the stirring shaft of the vaporization accelerator E or E', the hydraulic It is possible to measure the viscosity of the curing raw material, convert it into a slump value, and automatically adjust the slump value to the desired slump value by automatically generating air flow or adding water. can. Viscosity measurement uses a torque detector to convert the stirring resistance of the stirring rod caused by viscosity into a phase difference signal, and this phase difference allows for 1 til
A clock pulse is passed through a gate circuit to convert the phase difference into a pulse number, and this pulse is integrated and counted for a certain period of time to digitally measure the torque value generated due to viscosity. However, since the slump value of the hydraulic curing raw material is correlated with its viscosity, it is possible to convert the viscosity of the viscosity measurement control device into the slump value using experimental values etc. By adding water or generating air flow as necessary, the slump value can be automatically adjusted to the desired slump value. The slump value of the hydraulic hardening raw material when kneading is stopped can be measured by rotating the stirring rod of the viscosity measuring device in the hydraulic hardening raw material and converting the viscosity obtained by the stirring resistance into the slump value. can. Further, it goes without saying that the slump value may be directly measured instead of the viscosity without converting the viscosity into the slump value for both the viscosity measurement device and the viscosity measurement control device.

Next, the t overcompressive strength of a hydraulic hardening raw material using cement as a hydraulic substance, river sand as a fine aggregate, and river gravel or crushed blast furnace slag as a coarse aggregate is displayed. The mixing ratio of the hydraulic hardening raw materials is 300 parts by weight of cement (Portland cement), 7 gO parts by weight of river sand, and 1033 parts by weight of river gravel or crushed blast furnace slag, and in each case, the amount of water is varied. This reduces the slump value to 7.
Adjusted to. Further, test boils 1 to 10 used river gravel as the coarse aggregate, and test A//-20 used blast furnace slag crushed stone as the coarse aggregate.

Test Ryo 7 and /9 are aggregates with appropriate moisture content (aggregates and water are placed in a mixer, the pressure is reduced while kneading, the pressure is restored, the aggregate is sufficiently hydrated, and the air flow is used to absorb excess water while kneading). Aggregates that have had water removed and are sufficiently moist but do not leach water under normal conditions; they may be centrifuged to remove excess water), and are depressurized and reconstituted twice every 3 minutes. Cement paste made by pressure is kneaded for 4 minutes,
Test & 10 and Ko θ are suitable moisture content aggregate and cement 7
The mixture was kneaded for 1 minute, then water was added and kneaded for 2 minutes.

The pressure was reduced to 00 uHJi' in each case, and the pressure was restored rapidly. These pressure reductions and pressure restorations were all performed while kneading. Also, the compressive strength is 1? The strength increase rate is shown as % based on test A1.2-20, and test A1.2-20 is shown as % on the basis of test A1.2-20.

The above test was conducted using the casting method during the winter in Tokyo and was only allowed to cure naturally. Therefore, if it is carried out in warm weather and sufficiently cured, it is thought that the strength will be even greater.
