Abstract

The present invention relates to an aggregate screening device with a supplemental shooting device and, more specifically, an aggregate screening device with a supplemental shooting device installed on an upper end part of a vibration screen, which enables the supplemental shooting device to uniformly throw aggregates crushed by a crusher to the upper part of the vibration screen and accordingly screens aggregates uniformly via the entire screen net of the vibration screen, thereby increasing the penetration rate of the aggregate and leading to the yield rate of the aggregate. In the present invention, the provided aggregate screening device hardly provides enough opportunities for standard aggregates to be contacted to the screen net and prevents the standard aggregates from being selectively screened. Instead, the aggregate screening device is allowed to supply the standard aggregate via a collection belt conveyor on the lower end of the vibration screen to the crusher and to re-inject the same to the vibration screen, thereby reducing an amount of unnecessary circulated aggregates and thus improving the efficiency of driving the aggregate screening device.

Description

{AGGREGATE SORTER WITH SUB-CHUTE}

The present invention relates to an aggregate separator equipped with an auxiliary chute, and more particularly, to an aggregate separator equipped with an auxiliary chute at an upper end of a vibrating screen, wherein the aggregate crushed by the crusher is uniformly dropped onto the vibrating screen by the auxiliary chute, It is possible to increase the aggregate production efficiency by increasing the aggregate permeability through the whole net. Particularly, the aggregate aggregate which is not provided with sufficient opportunity of contact with the screen mesh is not sorted by the screen screen but supplied to the crusher through the collection belt conveyor at the bottom of the vibration screen, and then re- To an aggregate sorter capable of minimizing the size of the aggregate and improving the device driving efficiency.

Generally, in a quarry or a construction waste intermediate treatment facility producing aggregate or waste aggregate, an aggregate production apparatus having a vibration screen having a plurality of crushers and a multi-layer screen network is installed to produce aggregate, .

The driving of the vibration screen transfers the aggregate crushed in the crusher to the top of the vibrating screen by the belt conveyor, and the conveyed broken aggregate is guided by the belt conveyor directly or by the guide plate and dropped onto the vibration screen.

The crushed aggregate dropped onto the vibrating screen is intensively stacked on the central portion of the screen net of the vibrating screen, and the aggregate is extended downward along the inclined surface by the transmitted vibration, so that the aggregate extends widely to both sides of the vibrating screen. The aggregate of the following aggregate is passed through the bottom of the screen net and the aggregate of the screen net size or more is not passed through the screen net and is pushed down to the bottom of the vibrating screen and supplied to the crusher by the recovered belt conveyor, So that aggregate sorting can be performed.

If the crushed aggregate is excessively accumulated at the center of the screen screen, the crushed aggregate falls down along the slope of the screen screen due to the vibration, and sufficient contact with the screen screen is not achieved. But is recycled to the crushing process by the collection belt conveyor.

That is, since some of the standard aggregates have no time and space to pass through the screen net and are repeatedly subjected to the crushing process repeatedly, the aggregate production efficiency per hour is lowered, and the crushing process is repeatedly performed There is a problem that the dust generation amount is increased and the life of the equipment is shortened due to the consumption of parts of the crusher for the aggregate breakage.

In order to solve this problem, a device has been proposed in which a metal member in the form of a horizontal protrusion-preventing jaw is provided at the upper end of the screen net to delay the time for transporting the broken aggregate to the lower portion of the vibrating screen, thereby allowing the broken aggregate to stay on the upper portion of the vibrating screen.

However, in the conventional method, the amount of aggregate descending to the screen net of the vibration screen is delayed to provide a time for the standard aggregate to pass through the screen net. However, since the aggregate sorting time is relatively slow, .

Therefore, there is a need for a study of a device capable of preventing the reduction of the aggregate production amount while preventing the standard aggregate from circulating and performing the further crushing process.

Accordingly, in the aggregate sorter of the present invention,

The present invention aims to provide a device for increasing the efficiency of aggregate production by allowing standardized aggregates to be screened through the entire screen net by uniformly dropping the broken aggregate crushed by the crusher in the width direction from the top of the screen net of the vibration screen.

According to an aspect of the present invention, there is provided an aggregate sorter comprising:

The pulverized aggregate, which has been crushed from the crusher, is conveyed to a feed belt conveyor and supplied to a vibrating screen.

One or two or more vibration generating means may be provided to increase the vibration power, and vibration may be directly transmitted to the blocking side wall so that vibration is indirectly transmitted to the screen net through the blocking side wall.

The aggregate sorter (10) of the present invention comprises a supply belt conveyor (40). The supply belt conveyor 40 supplies crushed aggregate, which is crushed by one or a plurality of crushers 50, to an upper sloped portion of the upper screen net 21 of the vibrating screen 20.

An auxiliary chute 30 is installed between the vibrating screen 20 and the supply belt conveyor 40 so that the crushed aggregate supplied from the supply belt conveyor 40 is conveyed to the upper portion of the upper screen net of the vibrating screen So that a uniformly large release is made in the width direction.

The auxiliary chute 30 includes a spray chute 32 having a receiving part formed therein and a support 31 coupled to both sides of the spray chute.

The spray chute portion 32 is located at an upper portion of the upper screen net, and has an inlet 321 for inserting crushed aggregate at the upper end thereof and an outlet 322 for discharging the crushed aggregate material at the lower portion thereof. The spraying chute 32 is formed to have a cross section with a vertical cross section so that the crushed aggregate can be easily introduced into the upper inflow port by the supply belt conveyor while the lower discharge port 322 is formed in the entire width of the upper screen net So that evenly distributed crushed aggregate is distributed over the entire upper screen net width.

As shown in FIG. 3, the spray chute 32 has a right triangular cross-section formed at a right angle with the front surface, and the discharge portion 322 is formed at the bottom of the front surface. Further, the rear surface is formed by the inclined surface 323 having a downward inclination such as the upper screen net of the vibrating screen, so that the broken aggregate supplied to the upper part of the spraying chute 32 spreads and is spread widely in the width direction inside the spraying chute, Guided to the inclined rear surface, and discharged through the discharge port 322 in the widthwise direction on the inclined upper portion of the upper screen room of the vibration screen. This inclined rear surface 323 guides the loaded crushed aggregate in the traveling direction of the upper screen screen to be discharged so as to prevent the stacked crushed aggregate from being stacked in the upper screen screen screen.

4, the spraying chute 32 is formed such that the front surface and the upper surface are formed at right angles, the upper surface and the lower surface are formed horizontally, and the rear surface is formed to have a right angle oblique angle formed by the inclined surfaces 323 And the discharge port 322 may be provided in a form formed on the bottom surface of the lower end. In addition, the spray chute portion may be provided in various forms such that the rear surface has an inclined surface similar to the inclined direction of the upper screen screen net, and the discharge port is formed so as to discharge the crushed aggregate over the entire width of the upper screen net.

In addition, the spray chute portion 32 may further include an auxiliary plate at the upper portion thereof to further expand the internal space of the spray chute portion. The coupling of the assisting plate can be firmly coupled using various fastening means such as bolts.

The supporting base 31 is fixed to the blocking side wall 23 of the vibration screen so that the vibration transmitted to the blocking side wall is transmitted to the spray chute 32 through the support base 31 so that the crushed aggregate can be easily transported to the discharge port of the spray chute .

As shown in FIG. 5, for example, a mounting hole 231 may be formed perpendicularly to the blocking side wall 23, The vibration screen and the auxiliary chute can be coupled by inserting the support 31 of the auxiliary chute into the hole. At this time, it is preferable that the installation hole 231 is formed to have a size similar to the diameter of the support bar so that the gap between the installation hole and the support bar is minimized. Also, by using a bolt or a fastening means, the supporting base and the blocking side wall are firmly coupled to each other, so that the support can be prevented from being moved or detached in the installation space due to the impact in the course of supplying the vibration or crushed aggregate to the booster chute. In addition, the length of the supporter is long to insert the installation hole, so that it is prevented that the supporter is easily detached by impact.

6, a guide bar 232 having a vertical through-hole is rigidly coupled to the outer side surface of the blocking sidewall 23, and the support base 31 is inserted into the guide bar 232, 20 and the auxiliary chute 30 can be combined. The guide rod 232 may be firmly coupled to the blocking side wall 23 by welding or fastening means and the cross section of the guide rod may be formed to be the same as or similar to the cross section of the support rod to minimize the occurrence of vibration due to the spacing gap It is preferable to be angry.

In other words, as the latching base 234 is coupled to the lower side from a plurality of vertically arranged height adjusting holes 233, the depth of the inside of the support is deepened so that the discharge portion of the spraying chute is disposed close to the upper screen screen, The engagement of the latch with the upper side can limit the depth of penetration of the support so that the discharge of the spraying chute can be separated from the upper screen screen. Here, the latch 234 may be a one-sided rod or may be screwed to form a screw thread on the inner surface of the height adjusting hole and the latch.

As described above, the vibrating screen 20 provided with the auxiliary chute 30 is a case where the aggregate supplied to the upper screen net 21 is lower than the mesh size of the upper screen net 21 by vibration, Passes through the upper screen screen net, is placed on the lower screen net 22 at the lower side and is transported to the lower side.

Therefore, since the aggregate discharged by the upper screen net 21 has a size equal to or larger than the standard aggregate, it is supplied to the crusher 50 by the circulating belt conveyor 60 to perform the crushing process again. Since the aggregate discharged through the lower screen net 22 is a standard aggregate, it is transported through the aggregate transport belt conveyor 70 to the loading site and loaded.

As described above, according to the present invention, the crushed aggregate crushed by the crusher 50 is supplied to the auxiliary chute 30, and the crushed aggregate supplied to the auxiliary chute 30 passes through the discharge port 322 of the bolt chute, So that the standard aggregate is sorted from the crushed aggregate through the upper and lower whole surfaces of the upper screen mesh to maximize the production efficiency of the standard aggregate.
