Processing device for surface peeling of recycled aggregates {Manufacturing Device of Remaking gravel}

The present invention relates to a processing apparatus for peeling the surface of recycled aggregates for the efficient recycling of construction waste.

In particular, in the present invention, in the production of recycled aggregate through the intermediate treatment process of construction waste, through the efficient post-treatment work, by producing a useful material that maintains low absorption rate and high quality quality, it significantly improves its utility and solves resource shortage and The present invention relates to an apparatus for peeling a surface of an improved function that can effectively cope with environmental conservation.

Conventionally, Patent Registration No. 235319 `` Intermediate treatment method for treating and recycling construction waste and its device '' proposed and registered by the present inventor for efficient recycling of construction waste is responsible for the primary processing production of useful materials of the present invention. In the traditional method of dividing the collected waste into crushing, sorting and washing, it adopts the method of blowing the waste and automatic sorting of the recycled aggregate using the waste blowing method and water at the flat screen drop point and compulsory to improve the recycled aggregate granularity. It is to produce high quality useful materials by applying return method.

To this end, first shredding means for shredding the collected construction waste to a predetermined size or less, a first transfer belt means including a charitable to remove the metal material mixed with the waste while accumulating and transporting the shredded waste, and the Vortex phenomena in order to facilitate the sorting and discharge of waste aggregates at the lower end of the first sorting means and the first sorting means for filtering the waste while vibrating to separate the transported waste into the sediment and the specific aggregate size. A blowing means for generating a water tank, a tank for allowing the selected aggregate to be washed by an underwater aeration tank including a high pressure water jet nozzle, and to be separated from the suspended solids; One forced material conveying means, and flocculation agent and water replenishment treatment for purification of separated water It is installed in the water tank tank so that the water recovery sedimentation tank and the washed aggregates can be sequentially drawn out, the second transfer belt means for separating the aggregates and water by laying a water recovery screen, and the withdrawn aggregates are also put into a constant size A second crushing means for crushing the crusher, a third transfer belt means for separating the remaining metal material with the charity while conveying the crushed aggregate, and the aggregate separated from the metal material is selected to a specific size or less and then each size The second sorting means discharged separately from each other, and the aggregate having a specified or more size addressed to the second sorting means, the fourth transfer belt means having a charity to be conveyed again and the returned aggregate is re-crushed to the specified size or less After the third crushing means is provided to be re-loaded in the second transfer belt means to be cyclically driven.

However, even in such a process, sometimes the aggregate is very coarse and difficult to use alone. The properties of the aggregate change depending on the size of the particles, and the smaller the particles, the lower the specific gravity and the higher the water absorption rate. One recycled aggregate has a smaller particle size, resulting in a greater amount of cement paste, which degrades the quality of the aggregate.

In other words, the absorption rate, which determines the general quality of aggregates, ranges from about 7 to 12%, which hinders its utilization as high-quality aggregates. The recycled aggregates obtained from the crushing of waste concrete are mortars attached to the aggregate surface. And appearance is significantly poor due to various impurities, the absorption rate of the aggregate itself is increased, and when it is put into the concrete and concrete products, the adhesion between the aggregate surface and the mortar is reduced, as well as the phenomenon of strength degradation due to crushing occurs. It contains a problem.

In order to overcome this problem, the present inventors have proposed and registered as Utility Model Registration No. 179245 by filling the pores of the aggregate surface with water glass coating method to improve the absorbency of the aggregate and improving the surface strength. It is not a reprocessing method of its own, but only filling the voids to improve the appearance, and it is difficult to remove the mortar and various impurities attached to the aggregate surface. In addition, the absorption rate is significantly increased by the mortar, causing the overuse of the water glass aqueous solution to be added, and thus including the closure of workability and economic burden.

Therefore, in the aggregate produced by the pre-registration processing device proposed by the present inventors, the surface of the aggregate itself is reprocessed to significantly remove the mortar and various impurities attached to the angular portion or the surface, thereby minimizing the cause of the increase in the absorption rate. And, when used as a concrete material, the purpose of the present invention is to provide a processing device that can increase the range of applications, such as increasing the adhesion and at the same time expect high quality.

The present invention to achieve the above object is a hopper; A vibrating screen sorting means, in which recycled aggregates introduced through the hopper are sequentially moved and supplied through a transfer means; An impact crusher in which aggregate of less than a certain size is introduced through a transfer unit through the screening process, and thus surface peeling is performed such as improving the granularity of the aggregate and removing mortar and removing impurities from the aggregate surface; The aggregate separated in more than a certain size in the screening process is conveyed through a separate conveying means by a forced return method to the crushing process to make the re-crushing process; A roll crusher in which the aggregate discharged through the cone crusher is crushed into fine aggregate and brought back into the impact crusher under the same conditions as the above-described aggregate having a specific size or less; An aggregate of water screen through which the impact crusher is introduced to be washed and sorted by size through a transfer means; It is characterized in that the technical configuration is provided through the water screen to below the specific size is separated and discharged to the gravel, more than that is returned to the roll crusher again, the lower dimension than the gravel dimensions are separated and discharged into the sand.

As shown in the present invention is a hopper (1) of excellent durability is provided so that the recycled aggregate produced by the first processing produced from the construction waste intermediate treatment device, the recycled aggregate introduced through the hopper 1 is a conveyor belt While falling appropriately sequentially into the conveying means 2 consisting of so as to be introduced in a predetermined unit to the sorting means (3) provided with a vibrating screen.

In the screening process of the sieve type through the screen, aggregates of more than and below a certain size can be separated, and aggregates of a certain size or less are solidified or aggregated on the surface of the aggregate through a conveying means 2a consisting of a conveyor belt. In order to remove the surface of the mortar protruding to the outside and remove impurities, it is introduced into the impact crusher (4) to undergo a predetermined crushing action to ultimately peel off the surface of the aggregate, the aggregate is separated into a specific size above Collected separately through the sorting means (3) is conveyed to the conveying means (2b) of the conveyor belt provided separately according to the forced return method for improving the shape of the aggregate is put into the cone crusher (5) to be re-crushed processing It is shredded to below dimensions.

At this time, the role of the cone crusher (5) may be achieved by replacing the impact crusher method, but the use of the cone crusher (5) is more preferable due to the consumption rate and maintenance cost of machinery parts, excessive time required, and lowering the operation rate of equipment.

In addition, the power generating device for driving the present invention is to operate by using an electric motor or to mount a separate engine to each device may employ a hydraulic drive motor, so that it is possible to move the position of the device for each process The trailer or caterpillar system can be adopted freely.

As such, the aggregates crushed and discharged through the cone crusher 5 are again broken into fine aggregates and transported to the above-described impact crusher 4 under the same conditions (size) as the aggregates below the specific size. The roll crusher 6 is freely set by the operator by dimension in the form of 2 rolls or 3 rolls while being transported through.

Thereafter, the aggregate peeled off via the impact crusher 4 is sequentially dropped and supplied to the water screen 7 provided so as to be appropriately placed in the transfer means 2d so that washing and sorting by size are performed. This allows for separation of aggregates from other suspended solids, as well as cleaning of various dirt on the aggregate surface.

In addition, the water screen 7 allows the recycled water and aggregate to be drawn out along the ramp while being separated from each other so that a specific size or less is separated and discharged into gravel, and more to the roll crusher 6 again. The material is returned and subjected to the above-described shredding process.

Through each of these processes, the dimension which is significantly lower than the gravel dimension is finally discharged as sand so that the gravel and sand can be circulated integrally by addressing the classifier 8 to the water screen 7 so that the gravel and the sand are respectively adaptable and commercially useful. It will be driven to complete the technical configuration means of the present invention.

Therefore, the present invention is a recycled aggregate produced by the first process through the intermediate treatment process of construction waste is more diverse as aggregate, the surface of the aggregate functioning to increase the absorption rate and decrease the strength to maintain excellent field adaptability, high quality By removing and removing the mortar and various impurities, it is possible to reinforce the crack and improve the appearance, and to significantly improve the aggregate shape of the aggregate, thereby increasing the bonding strength with the new mortar and at the same time strengthening the aggregate wear rate and effectively increasing the absorption rate. It includes the usefulness that can be prevented.
