Description

MILL OF RECYCLED AGGREGATE CRUSHED IN MIDDLE PROCESSING OF CONSTRUCTION WASTE}

The present invention relates to a crusher of the circulating aggregates crushed during the construction waste intermediate treatment process, more specifically, by rubbing the raw aggregates and crushing each other to remove foreign substances such as mortar on the surface of the raw aggregates and to remove sharp parts The present invention relates to a crusher of circulated aggregate crushed during the construction waste intermediate treatment process to obtain high quality recycled aggregate close to a spherical shape.

In general, when a concrete structure or various buildings are demolished at the end of their life, various wastes are discharged, including concrete masses including reinforcing bars, earth and sand around the building, and wood generated from various waste furniture and wooden door frames installed in the building. .

In order to save energy resources and reduce costs while preventing environmental wastes caused by such wastes, recycled aggregates are obtained by performing regeneration processing to be crushed and recycled to various raw materials.

Conventional typical recycled aggregate device is to crush concrete waste materials in several stages and crush them to a predetermined particle size, and then remove the intermediate aggregates (6 mm or less) by separating and removing reinforcing bars, wood, synthetic resins, and earth and sand in this process. Has been made to separate and screen waste concrete crushed aggregates shredded to a predetermined particle size and then reprocess them to obtain high quality aggregates.

Existing recycled aggregate treatment device has the corners of the cracks and crushed aggregates generated during the shredding process of waste concrete, so the crushed aggregates have to be split and the edges of the crushed aggregates must be polished. It was simply to break up the crushed aggregates and to break the edges of the crushed aggregates.

The recycled aggregate processing apparatus related to this technology is presented in Korean Patent No. 10-0413325, which is a waste concrete that is crushed in the interior of the body when the cylindrical body is rotated, the inner wall of the body by its own weight In this process, the adjacent intermediate aggregates, or between the intermediate aggregates and the inner wall of the main body, and friction or rolling contact phenomena occur, and are subjected to grinding and breaking action, It is characterized by the grinding action that weak particles are broken, and angled good quality particles change into round spherical shapes without angles.

However, in the above-described patent, intermediate aggregates, that is, the intermediate aggregates to meet each other to obtain a high quality round spherical intermediate aggregate, which is simply bumped by the weight of the intermediate aggregates of the intermediate aggregates Because it is to be broken or polished, even if the spherical particles can not be obtained properly and the spherical particles can be obtained, there is a problem that takes too much time.

The present invention is to solve the above problems, by rubbing and grinding the raw aggregates subjected to the pretreatment process, such as crushing each other to peel off foreign matters such as mortar on the surface of the raw aggregates and to remove sharp parts to close the spherical shape It obtains high quality recycled aggregates, and in particular, it provides a crusher of crushed recycled aggregates during the construction waste intermediate treatment process, which can improve the crushing efficiency and quickly discharge the crushed recycled aggregates by grinding them on a plane without rotating the raw aggregates. Its purpose is to.

The crusher of the crushed circulating aggregate during the intermediate process of construction waste according to the present invention for achieving the above object, is installed so as to move forward and backward while being inclined downward toward the ground and the upper liner of the porous bottom liner ; Forward and backward driving means for forcibly moving the lower liner back and forth; The lower liner is spaced apart from each other by a predetermined gap and includes an endless upper end liner having a concave-convex surface, and the lower liner and upper side are formed by a linear reciprocating movement force of the lower liner and the upper liner endless rotational force. It is characterized in that the foreign matter is peeled off the surface of the circulating aggregate friction between the liners and the circulating aggregate is crushed into a sphere.

According to the crusher of the circulating aggregates crushed during the construction waste intermediate treatment process according to the present invention, the raw aggregates rubbed between the lower liner and the upper liner, and the raw aggregates rubbed with the lower liner and the upper liner As a result, the grinding efficiency of the raw aggregates is improved, and as a result, foreign matters such as mortar on the surface of the raw aggregates are effectively peeled off, and sharp angular portions can be removed to obtain circular aggregates close to a spherical shape, thereby improving the efficiency of the recycled aggregates. Can be.

As shown in FIG. 1, the crusher of the circulated aggregate crushed during the construction waste intermediate treatment process according to the present invention has the lower liner 10 and the upper liner 20 spaced apart at regular intervals, and the lower liner 10 ) Is reciprocated forward and backward and the upper liner 20 rotates in an endless track (the direction of circulation aggregate) while peeling off foreign matter (eg, mortar) from the surface of the recycled aggregate by mutual friction of the recycled aggregate, and removing the sharp part of the recycled aggregate. To remove it.

As shown in Figures 1 to 3, the lower liner 10 is a plate and circulating aggregate, the upper surface of the concave-convex type (convex also performs the function of transferring the circulating aggregate A toward the discharge port) in order to increase the grinding efficiency of the circulating aggregate. It is porous having a plurality of foreign matter discharge holes (11) in order to discharge the foreign matter and fine powder peeled off.

The lower liner 10 may be installed through a separate frame 12. When the frame 12 is applied, the lower liner 10 is detachably fastened to the upper surface of the frame 12 through fasteners so as to reciprocate back and forth with the frame 10.

At this time, all parts of the lower liner 10 will not wear the same, and partial wear will occur, and when such a portion wears, the lower liner (to replace only the portion requiring replacement without replacing the entire lower liner 10) 10) is divided into a plurality of.

The lower liner 10 is disposed to be inclined downward toward the ground so that natural discharge of the circulation aggregate A is possible.

As shown in FIG. 3, the lower liner 10 is disposed under the upper liner 20 to provide a basic space for grinding, and the grinding aggregate A and / or foreign matter during grinding of the recycling aggregate A. Blocking jaw 13 is formed so that (W) does not escape through the width direction both sides of the lower liner (10).

The frame 12 should be installed so that left and right twisting does not occur during linear reciprocating movement. For example, the guide rail 15 is installed at the bottom of the frame 12 at regular intervals, and the guide rail is provided at the bottom of the frame 12. The roller 14 which linearly reciprocates along 15 is provided.

If the frame 12 is not applied, the roller 14 will be installed in the lower liner 10.

The upper liner 20, like the lower liner 10, is formed in the top surface is concave-convex to increase the grinding efficiency. The upper liner 20 will only perform the grinding of the circulating aggregate (A), so foreign matter discharge holes will not be formed.

Although the upper liner 20 may be crushed even when the lower liner 10 is reciprocated forward and backward, even in a stationary state, the circulating aggregate A may be inclined so as to naturally discharge through the inclination of the lower liner 10. It is configured in a rotating manner.

For example, the upper liner 20 may be manufactured and driven in a caterpillar shape, or may be detachably coupled to a surface of a separate caterpillar belt 21 through a fastener to be driven through the belt 21. .

The direction of rotation of the upper liner 20 maintains a direction (clockwise reference to FIG. 1) to assist without interfering with the discharge of the circulating aggregate (A).

The upper liner 20 is divided into a plurality for maintenance is the same as the lower liner 10.

The structure and driving method of the belt 21 is the same as the existing belt, so a detailed description thereof will be omitted.

However, one or more pressure rollers 22 may be provided to press the circulation aggregate A toward the lower liner 10 during the grinding of the circulation aggregate A.

The lower liner 10 and the upper liner 20 are made of special steel (such as high manganese) to minimize wear due to friction with the circulation aggregate (A), respectively.

The uneven portions formed on the lower liner 10 and the upper liner 20 are to increase the grinding efficiency through the convex portions, and the uneven portions are alternately repeatedly formed along the longitudinal direction of the lower liner 10 and the upper liner 20. .

For example, the lower liner 10, the frame 12, and the forward and backward driving means may adjust the height of the height adjusting means (for example, a cylinder, a stretchable double structure so that the grinding space can be adjusted according to the particle size of the circulating aggregate A). Adjustable legs) can be installed to adjust the height. Such a height adjustment structure is not specifically illustrated in the drawings, but will be fully implemented by those skilled in the art.

The forward and backward driving means for reciprocating the lower liner 10 forward and backward, for example, as shown in FIG. 5, is connected to the drive motor 30, the drive motor 30 and the frame 12, and the drive motor 30. It consists of the crankshaft 31 which switches the rotational force of to linear reciprocation motion.

In the drawings, reference numeral 1 is a product conveying conveyor for conveying a product (circulating aggregate A), and 2 is a foreign substance conveying conveyor for conveying foreign matter (W).

The action of the crusher of the crushed circulating aggregate during the intermediate treatment process of construction waste according to the present invention is as follows.

The raw aggregate (which refers to a state where there are foreign substances such as mortar and sharp parts on the surface) is injected into the space between the lower liner 10 and the upper liner 20, that is, the upper surface of the lower liner 10. .

Before the input of the raw aggregate, the lower liner 10 is moved back and forth through the forward and backward driving means, and the upper liner 20 rotates indefinitely in the discharge direction of the circulating aggregate A (left of FIG. 1).

Thus, the raw aggregate injected between the lower liner 10 and the upper liner 20 is compressed by the lower liner 10 and the upper liner 20 in the gap between the lower liner 10 and the upper liner 20, In this process, foreign substances on the surface of the aggregate are peeled off by the physical impact and sharp edges are removed.

In addition, the raw aggregate is more effectively crushed between the convex portions of the concave and convex portions of the lower liner 10 and the upper liner 20 to effectively remove the foreign material and sharp edges.

In addition, when the lower liner 10 moves forward, since the lower liner 10 and the upper liner 20 move in opposite directions, foreign material peeling of the raw aggregate and removal of sharp parts may be more effectively performed. That is, the lower liner 10 may move the raw aggregate to the outlet side while grinding the raw aggregate while moving backward (in the opposite direction to the rotation direction of the upper liner 20) and moving forward (the same direction as the rotating direction of the upper liner 20). Can be.

Since the raw aggregate is continuously crushed while moving toward the product conveying conveyor 1 along the lower liner 10 and the upper liner 20, the circulating aggregate A falling on the product conveying conveyor 1 may be formed on the surface such as mortar. It is close to a sphere with no foreign objects and no sharp parts.

On the other hand, through the foreign matter discharge hole 11 of the lower liner 10, foreign matter, fine powder, etc., which are ground by the lower liner 10 and the upper liner 20, are discharged to the foreign matter transfer conveyor 2. At this time, since the lower liner 10 reciprocates forward and backward, the foreign substance discharge hole 11 may be discharged without clogging the foreign substance W.
