Description

Normal temperature ascon and method and device for manufacturing the same

The present invention relates to the field of room temperature ascon used for emergency repair at various construction sites, and more particularly, new room temperature ascon and the new room temperature to allow the bonding force and the strength to be improved by using some mixture in the limestone as a filler. The present invention relates to a method for manufacturing room temperature ascon and a device for manufacturing the same to allow production of ascon to be improved and productivity can be reduced.

In general, room temperature ascon is a non-heated ascon that has a property of rapidly hardening under conditions of normal temperature when exposed to air, and is particularly useful as an emergency road repair construction material that fills the excavated parts of various roads. .

Specifically, the room temperature ascon is used not only for road emergency repair but also as a filler around the manhole or bridge joint and as a refractory filler for cable ducts.

In other words, the road may not be able to bear the load due to the traffic of the vehicle, and the pie may be partially destroyed for various constructions, and all of the dug shall be repaved to fill the excavated portion as ascon.

However, if the road area for resurfacing is large, the road is paved with ordinary ascon (heated ascon) with the vehicle or human traffic completely prohibited for a certain period of time. Asphalt is packed at room temperature as quickly as possible without interfering with the traffic. This is used for construction work with long working time because it is not cheap in general ascon but hardly hardens when exposed to room temperature. It is used for construction with short working time because it hardens quickly when exposed to room temperature instead of expensive.

On the other hand, the general ascon is a heated ascon, as described above, it does not harden rapidly even when exposed to room temperature, so it is carried directly to the construction site without a sealed packaging from the manufacturer, but the room temperature ascon is a non-heated ascon. As described above, when exposed to room temperature, it hardens rapidly, so that it is hermetically packed in small packing units at the manufacturer and moved to the construction site.

The room temperature ascon is usually aggregate + binder (non-heated asphalt) + filler (limestone), if the total mixture is classified, the aggregate is 80% by weight, the binder is 6% by weight, the filler is 14% by weight. The aggregate is made up of 25% of the aggregate aggregate of about 6 mm in particle size and 55% of the aggregate of about 3 mm in particle size.

The binder is used to maintain the bonding strength between the aggregates is excellent in viscosity, but when exposed to room temperature non-heated asphalt is used, the filling material serves to fill the gap between the aggregate and aggregate. Limestone is used which is easy to purchase at low price.

The manufacture of such room temperature ascon has been manufactured by relying on individual devices, not depending on the system that has been systemized as a whole, as described in more detail as follows.

Using a separate device, the main material particle diameter of 6 mm aggregate and particle diameter of 3 mm are separated and provided, and the limestone as a filling material is provided, and then the aggregate of 6 mm, particle size 3 mm aggregate and limestone are used by using a separate meter. Weigh each to the appropriate amount.

Put the measured amount of aggregate (6 mm aggregate and 3 mm aggregate) and the appropriate amount of limestone into one blender, and at the same time put the appropriate amount of non-heated asphalt as a binder into the blender, and then mix the aggregate, limestone and asphalt. After mixing well, the room temperature ascon is not completely sealed. After manufacturing, the room temperature ascon is not sealed and then weighed by an appropriate amount as another separate meter and put into a wrapping paper.

However, the conventional manufacturing of such room temperature ascon has a problem that productivity is greatly reduced due to deterioration of workability because the facilities for the manufacture are not systemized and are separated separately, and the selling price of the product is increased due to the increase in the production cost of the product. There was a problem.

In addition, the room temperature ascon prepared by the conventional manufacturing device is composed of 80% by weight of aggregate + 6% by weight of binder + 14% by weight of filler, the aggregate of the 80% by weight of the aggregate having a particle size of about 6mm 25% and the particle size Aggregate of about 3mm is divided into 55%, which is intended to be hardened quickly at room temperature, but it does not seem to pay much attention to problems that may occur after use.

Therefore, the room temperature ascon manufactured by the conventional apparatus is mainly used for the temporary paving of the excavated parts such as roads, even after a certain time after construction. There is a problem due to cracking, because the binding force of the aggregate, the main material of room temperature ascon is maintained only by the asphalt and the filler limestone as a binder.

It is understandable that if the amount of asphalt and limestone is increased and the amount of aggregate is reduced to increase the binding strength of the aggregate, which is the main material, the strength becomes weaker than necessary, which is not preferable.

The present invention has been made in order to solve the above-mentioned conventional problems, it is an object of the present invention to provide a room temperature ascon to improve the bonding strength of the aggregate as a main material while improving the strength by varying the material mixture of the room temperature ascon.

In addition, the present invention aims to systemize the production equipment for the production of the room temperature ascon to reduce the selling price of the product due to the reduction of the production cost while contributing to the increase in productivity by improving the workability in the production process. .

The object of the present invention is 80% by weight aggregate + 6% by weight of the binder + 14% by weight of the filler material is mixed, the aggregate consists of 25% aggregate having a particle diameter of about 6mm and 55% aggregate having a particle diameter of about 3mm In the filling material is 9 to 11% by weight of limestone polypropylene fiber + 1 type Portland cement + 3 to 5% by weight of a separate mixture consisting of aggregates having a particle diameter of 1.8mm to provide room temperature ascone Can be achieved by

In addition, another object of the present invention is the primary screen step and the primary screen step to filter out the aggregate of more than the thickness (particle diameter of 6mm or more) of the aggregate, as well as filtering foreign matter of the aggregate and limestone as the main material Drying step of high-temperature drying the aggregate and limestone from which foreign matters are filtered out, and secondary screening step of filtering the dried aggregate and limestone to classify aggregate only about 6 mm and 3 mm in diameter and separate limestone separately And, temporarily discharging the aggregate and limestone classified by the secondary screen, and then selectively discharging them by an appropriate amount, and polypropylene fiber + one kind of portland cement in the limestone discharged selectively by the secondary screen. + A mixture addition step comprising a small amount of the mixture consisting of aggregates having a particle diameter of 1.8 mm, and the appropriate amount of bone selectively discharged And a mixing step of receiving an appropriate amount of non-heated asphalt as a binder and mixing it with each other separately to form a room temperature ascon, and mixing the limestone + non-heated asphalt with the aggregate + mixture added thereto It can be achieved by providing a method for producing a room temperature ascon characterized in that the metering step of quantitatively measuring the room temperature ascon in a state, and the packaging step of sealing packaging the room temperature ascon measured in the quantitative manner is sequentially performed.

Another object of the present invention is the first conveyor means for transporting the aggregate selected as the main material in the horizontal direction or the limestone serving as the filling material in the horizontal direction, the aggregate selectively transported by the first conveyor means and The primary catching member for filtering the foreign matter of limestone and filtering the aggregate having a thickness larger than necessary (particle diameter of 6mm or more) among the aggregates, the aggregate in which the foreign matter is filtered out of the primary filtering member, and A dryer for drying limestone at a high temperature, a second conveyor means for selecting and transporting aggregate and limestone passed through the dryer to a vertical upper portion, and foreign matter of aggregate and limestone selectively transported by the second conveyor means.

It can be achieved by providing an apparatus for manufacturing a room temperature ascon characterized in that the packaging machine for receiving and measuring the sealed room temperature ascon.

Hereinafter, the present invention will be described in detail by way of examples.

The present invention is to provide a room temperature ascon and a method for manufacturing the room temperature ascon and the device, the room temperature ascon of the present invention is a mixture of 80% by weight + 6% by weight of the binder + 14% by weight of the filler, the aggregate is The filler is composed of 25% of aggregate having a particle diameter of about 6 mm and 55% of aggregate having a particle diameter of about 3 mm, wherein the filler is 9-11% by weight of limestone and aggregate of polypropylene fiber + 1 kind of Portland cement + 1.8 mm of particle diameter. It contains 3 to 5% by weight of a separate mixture consisting of.

In the mixture constituting the filler, the polypropylene fiber, the first portland cement, and the aggregate having a particle diameter of 1.8 mm are extremely small when the amount is based on the total amount of the ambient temperature ascon of the present invention, and there is no need to particularly limit the amount thereof. According to the choice of a skilled worker may be used in an appropriate amount, it will usually be divided equally by the same amount.

In the mixture, the polypropylene fiber wraps the aggregate, which is the main material, and connects the aggregate and the aggregate, and the first type of Portland cement has the viscosity of the non-heated asphalt, which is the binder, as the polypropylene fiber is included in the limestone, which is the filler. As it may fall, it serves as a supplementary material to compensate for this, and the aggregate of 1.8 mm in particle size is present in the filling material and serves to enhance the strength between the main aggregates having a much larger particle size.

On the other hand, the polypropylene fiber is preferably used to cut the length to 15-20㎜, which is less than the tangling force in the process of use when the length is less than 15mm is not very helpful in improving the strength and bonding strength, the length is 20 In the case of ㎜ or more, the kneading force is too strong in the use process, so that it does not mix well in the mixing process, and this also does not greatly improve the strength and bonding strength.

A mixer 14 is installed to receive the weighed binder and mix with each other to form a room temperature ascon once unpacked, and the first, second, third and fourth storage tanks 7 (1) on one side of the fourth storage tank 12 ( 8) (9) (14), separate from polypropylene fiber + 1 portland cement + particle size 1.8 The fifth storage tank 15 is installed to store the mixture made of aggregate and then guide it onto the discharge passage of the third storage tank 9 through which limestone is discharged, so that the mixture contains some mixture in the discharged limestone. Directly below the mixer 14, there is provided a third meter 16 for receiving the room temperature ascon mixed by the mixer and quantitatively measuring the meter, and directly below the third meter 16 by the third meter 16. A packing machine 17 is provided to seal and package a room temperature ascone, which is quantitatively measured, and each of the operable components is electrically connected to be controlled to be monitored by a controller (not shown). to be.

At one side of the fifth tank (15), the mixture (polypropylene fiber + one kind of portland cement + aggregate of 1.8 mm particle size) stored in the fifth storage tank is premixed before storage, and the mixture is stored in the fifth storage tank (15). A mixer 18 is provided for automatically feeding the mixer, which is only necessary for automatically mixing the mixture and then storing it in the fifth reservoir 15. If the mixture is mixed by other means and then manually It can be understood that when moving to Article 5 Major 15 by the storage is not necessary.

The process of manufacturing room temperature ascon by the apparatus for manufacturing room temperature ascon according to the present invention will be described.

First, before the apparatus of the present invention is operated, the aggregate should be stored in the aggregate storage tank 19 provided directly above the first conveyor means 1, as well as limestone in the limestone storage tank 20. The fourth storage tank 12 should be filled with non-heated asphalt as a binder, and the fifth storage tank 15 should be filled with a mixture of polypropylene fiber + one portland cement + aggregate of 1.8 mm particle size. The preparation step to be put is necessary, the mixture to be filled in the fifth reservoir (15) during the preparation step is mixed in the mixer 18 installed on one side of the fifth reservoir and then to the fifth major (15) Alternatively, the mixture may be automatically fed and filled, or alternatively, the mixture may be separately mixed from the outside and then manually fed into the article 5 (15).

In this way, when the preparation step is completed, first, the aggregate filled in the aggregate storage tank 19 is discharged, and the discharged aggregate is horizontally moved to one side through the primary conveyor means 1 and then one side of the primary conveyor means. Entering into the dryer (3) installed in, the aggregate is passed through the primary filtering member (2) before entering the dryer (3) by the primary conveyor means (1) foreign matter contained in the aggregate in this process (Straw, twigs, pieces of paper, etc.) and coarse aggregates with a particle size of 6 mm or more are caught, so aggregates that have finally entered the dryer 3 are aggregates that do not exceed 6 mm in particle size, and are somewhat clean. It is possible.

Aggregate entering the dryer 3 stays in the dryer for 10 to 20 seconds and then discharged. At this time, since the internal temperature of the dryer is about 100 to 130 ° C., the aggregate passing through the dryer 3 has its own temperature of about 100 ° C. 1 If there is a wet aggregate in the state passing through the car trapping member (2), all the moisture is evaporated to become only dry aggregate, in this process, all the fine sand or soil that is stuck to the wet aggregate is separated All aggregates will be cleaner.

Subsequently, the aggregate passing through the dryer 3 is vertically moved upward by the secondary conveyor means 4, and passes through the secondary filtering member 5 in this process, while passing through the secondary filtering member. Among the aggregates, the aggregates are divided into aggregates having a particle size of about 6 mm, aggregates having a particle size of about 3 mm, and the remaining aggregates. Among the divided aggregates, aggregates having a particle diameter of about 6 mm are guided to one side from the supply guide member 6, and then the first storage tank ( 7) Aggregate having a particle size of 3 mm is supplied to the other side from the supply guide member and then supplied to the second storage tank 8 and stored, and the remaining aggregate and foreign matter are guided to the other side and discarded. All.

In addition, the secondary conveyor means (as the limestone is stored in the limestone storage tank 20 is transferred through the same process as described above (the object is changed from aggregate to limestone, and the process is the same as when transferring the aggregate). When passing through 4), the limestone is filtered and filled into the third reservoir 9 by the guide of the supply guide member 6 after the foreign matter is filtered out once more in the secondary screen process.

Then, the aggregate having a particle size of about 6 mm stored in the first reservoir 7, the aggregate having a particle size of about 3 mm stored in the second reservoir 8, and the limestone stored in the third reservoir 9 rose while passing through the dryer 3. The self-temperature is selectively discharged by the discharge guide member 10 in a state where it is separated by natural cooling (30 to 60 ° C.), and the discharged aggregate and limestone are weighed in an appropriate amount by the first meter 11 and then a blender. Entering (14), wherein the binder (non-heated asphalt) stored in the third storage tank (9) is weighed in an appropriate amount by the second weighing machine (13) and then enters the mixer (14).

On the other hand, when the limestone stored in the third reservoir 9 is discharged by the discharge guide member 10, the mixture (polypropylene fiber + one kind of portland cement + particle diameter of 1.8 mm) stored in the fifth reservoir 15 Aggregate) is guided to the discharge line of the limestone and mixed, so that the limestone which is finally metered by the first meter 11 and entered the mixer 14 has a mixture of polypropylene fiber + one kind of Portland cement + aggregate of 1.8 mm particle size. It is understood that it is included.

Through this process, when the mixer 14 receives the appropriate amount of aggregate and limestone containing the mixture and the non-heated asphalt as a binder, the mixer operates, so that the limestone and the non-heated asphalt as the binder are evenly distributed. The mixed room temperature ascon is manufactured while being unpacked, and the room temperature ascon in the unpacked state is quantitatively measured by the third meter 16 and then sealed and packed by the packing machine 17. This manufacture is complete.

When the room temperature ascon of the present invention is manufactured by the above device, all components that are powered and operated are controlled by a controller (not shown). In this case, the control state is designed to allow a driver to monitor through a monitor.

When manufacturing the room temperature ascon with the above-described apparatus of the present invention, the aggregate having a particle size of about 6 mm which is weighed by the first weighing unit 11 and entered the blender 14 is 25% by weight, and the first weighing machine 11 is used. 55% by weight of aggregate having a particle size of about 3 mm and weighed by the mixer 14, and 14% by weight of the filler material metered by the first meter 11 and entered into the mixer 14, and the second meter. When the weight of the binder entered into the mixer 14 is measured by (13) to 6% by weight, the room temperature ascon of the present invention in the finished state is made of 80% by weight of aggregate + 6% by weight of binder + 14% by weight of filler. At this time, the limestone stored in the fifth storage tank 15 and then guided to the discharge line of the third storage tank 9 (polypropylene fiber + one kind of portland cement + aggregate having a particle diameter of 1.8 mm) by 3 to 5% by weight of limestone If it is to be included in the eventually filling the room temperature ascon of the present invention 14% by weight would be limestone is 9 to 11% by weight and 3-5% by weight of mixture of polypropylene fiber + 1 kinds of portland cement + aggregate having a grain size 1.8㎜.

Therefore, in the present invention, the room temperature ascon contains a mixture made of polypropylene fiber + one type of portland cement + aggregate of 1.8 mm in particle size in limestone as a filling material. Even after a long period of time after being used in various construction sites, the crack does not occur or is effective.

In addition, the apparatus for manufacturing the room temperature ascon of the present invention has the effect that the productivity is greatly increased due to improved workability as well as the overall price of the product as well as the economic effect of lowering the selling price of the product due to the reduction of the production cost of the product. .
