The vibrating unit 600 is provided with a screen 400 and a dewatering screen 500 for screening and dewatering.

The main frame 100 is a steel frame structure provided with an I beam or H beam so as to have a space capable of accommodating the tank hopper 110 therein. A tank hopper 110 is provided in the main frame 100 so as to be positioned within the main frame 100 under the vibration frame 200 and a discharge pipe 120 is provided at the lower end of the tank hopper 110, A circulation water pump 130 is provided at the end of the tank hopper 110 and a drainage discharge box 140 is provided on one side of the upper end of the tank hopper 110 to allow the washing water flowing in the tank hopper 110 to overflow. In addition, a maintenance opening / closing outlet 150 for inspecting and cleaning the tank hopper 110 may be provided at the lower end of the tank hopper 110.

4, the vibrating frame 200 includes a front plate 210 and a rear plate 220 which are formed in a ladder shape, and at the upper and lower ends of the front plate 210 and the rear plate 220, A plurality of first and second reinforcing frames 230 and 240 are arranged so as to be spaced apart from each other in the first and second reinforcing frames 230 and 240. The first and second reinforcing frames 230 and 240 are provided with first and second profile bars 234 and 242, The screening screen 400 and the dewatering screen 500 are mounted through the first and second screens 236 and 244, respectively.

One of the front plate 210 and the rear plate 220 is provided with a reinforcing frame 200 for reinforcing the strength of the vibration frame 200 and a mixture of the aggregate and the washing water is provided on one side of the vibration frame 200, A first upper louver plate 250 and a lower second louver plate 260 are mounted so as to prevent scattering and overflow of the mixture when supplied from the upper part of the first and second louvers 400 and 500.

A plurality of first reinforcing frames 230 are arranged on the top of the front plate 210 and the rear plate 220 in the direction of terminating the first reinforcing frame 230. The first reinforcing frame 230 is disposed on the housing 610 of the vibration unit 600, They are arranged in an array at an angle.

A plurality of first profile bars 234 fixed to the upper ends of the first reinforcing frames 230 through the respective brackets 232 in a direction transverse to the first reinforcing frames 230 are fixed and fixed at regular intervals, 234, and the screen 400 is securely seated by a plurality of first locking bars 236 (see FIGS. 7 and 8).

A plurality of second reinforcing frames 240 are arranged in the direction of terminating the second reinforcing frame 240 at the lower ends of the front plate 210 and the rear plate 220. The second reinforcing frame 240 is disposed below the housing 610 of the vibration unit 600, And are arrayed in a line at an inclined angle.

A second profile bar 242 is provided on the upper end of each second reinforcing frame 240 in a same direction as the second reinforcing frame 240 and the second profile bar 242 is provided with a dewatering screen And the dewatering screen 500 is firmly fixed by the plurality of second locking bars 244 (see FIGS. 7 and 8).

The screen 400 is provided on the upper part of the vibration frame 200 and is a mesh of 5 mm for sorting the coarse aggregate and the fine aggregate. The dewatering screen 500 is provided below the screen 400, 400 to remove fine sludge and washing water while sorting only fine aggregate in a mixture of fine aggregate and washing water. The upper screen screen 400 of the vibration frame 200 and the fine aggregate and the fine aggregate are selected in one vibrating frame 200 in which a dewatering screen 500 is integrally provided at a lower portion of the vibrating frame 200. [ As well as the washing water mixed with the fine aggregate can be removed and dewatered efficiently and effectively.

The screen 400 is installed so as to have a downward angle? Downwardly from one side to the other and the dewatering screen 500 is arranged to be arranged in a direction opposite to the screen 400 Is set to have an upward angle (?) Inclined upward gradually. The downward angle alpha of the screen 400 is inclined downward by 5 to 8 degrees with respect to the horizontal line and the upward angle beta of the dewatering screen 500 is inclined upwardly by 3 to 7 degrees with respect to the horizontal line Do.

When the downward angle alpha of the screen 400 is more than 8 degrees, the coarse aggregate flows down too fast due to the inclination of the screen 400, alpha] is less than 5 DEG, the conveying speed of the coarse aggregate is slow and the phenomenon of stagnation on the screen 400 may occur.

If the upward angle? Of the dewatering screen 500 exceeds 7 °, the excitation force for transporting the fine aggregate selected by the dewatering screen 500 must be increased, and the fine aggregate on the dewatering screen 500 If the upward angle β of the dewatering screen 500 is less than 3 °, the conveying width of the fine aggregate is large and the dwell time is short, so that proper screening and dewatering can not be performed.

Since the dewatering screen 500 is a mesh of 0.8 mm, the mixture of the fine aggregate and the washing water dropped through the screen 400 can not be dewatered instantaneously in a short period of time, It is preferable that an upright dewatering screen 510 is provided on the inner wall surface of the second louver plate 260 as well as the front and rear plates 210 and 220 which are the ends of the dewatering screen 500 so as to prevent the dewatering and effective dewatering.

The vibration unit 600 is provided with a housing 610 having an eight-sided cross-section shape transverse to the vibration frame 200. The two first and second cam shafts 620 and 630 are passed through the housing 610 in parallel And the first and second camshafts 620 and 630 are provided with cam-gears 622 and 632 at both ends of the camshaft 620 and 630 so as to rotate in the reverse direction (see FIGS. 12 to 15). The first and second camshafts 620 and 630 and the first and second cam-gears 622 and 632 are arranged such that the center of gravity of the first and second camshafts 622 and 632 is opposed before reaching the top dead center of (b) It is preferable that the forces generated while being rotated in different directions are concentrated toward one point on the vibration unit 600 so that a high vibration force is generated. At this time, the eccentric directions of the first and second camshafts 620 and 630 and the first and second cam-gears 622 and 632 must be eccentrically assembled in the same direction.

The center line of the housing 610 and the center line of the first and second camshafts 620 and 630 are inclined angles of installation of the vibration unit 600 and have the same downward angle α as the screen 400 It is preferable that the angle of inclination of the vibration unit 600 and the upward angle of the dewatering screen 500 are inclined. In other words, when the inclination angle of the screen 400 is 7 ° and the inclination angle of the dewatering screen 500 is 5 °, the mutual inclination angle is 12 °.

A slant reinforcement plate 270 is provided on the front and back plates 210 and 220 of the vibration frame 200 on which the both ends of the housing 610 of the oscillation unit 600 are mounted, Since the vibrations generated by the vibrating frame 200 are transmitted to the entire vibrating frame 200 through the front and rear plates 210 and 220 of the vibrating frame 200 and the vibration of the front and rear plates 210 and 220 forming the vibrating frame 200 So as not to be deformed or damaged.

In particular, the diagonal reinforcing plate 270 is provided so as to be inclined upwards from one side (left to right in the drawing). The reason why the slant reinforcement plate 270 is provided in an upward sloping manner is that the center of gravity of the first and second camshafts 620 and 630 and the first and second camshafts 622 and 632 are opposed before reaching the rising point, The vibrating frame 200 is subjected to an impact force (excitation force) in an oblique upward sloping direction from one side to the other side as a result of continuously repeating the process of generating a high vibration force with an improved amplitude, that is, So as to effectively prevent damage to the front and back plates 210 and 220 which may be caused thereby.

The driving motor 640 for driving the first camshaft 620 of the vibration unit 600 absorbs the vibrations of the first and second camshafts 620 and 630 and at the same time absorbs vibration of the first and second camshafts 620 and 630 of the vibration frame 200, The tension of the belt connected to the belt 620 and 630 must be kept constant. The drive motor 640 is mounted on a motor support 650 connected to the main frame 100 through a hinge shaft 652. The motor support 650 rotates about a hinge axis 652 within a predetermined angle range The first and second elastic members 670 and 680 are attached to the rod 660 so as to support the upper side and the lower side of the motor support 650, (See FIG. 16).

The process of selecting and dehydrating aggregate from coarse aggregate and fine aggregate by using the apparatus for sorting and dewatering aggregate according to the present invention will be described in detail.

First, when the driving motor 640 on the main frame 100 is driven, the first camshaft 620 of the vibration unit 600 connected to the driving motor 640 and the belt 642 is rotationally driven, Gears 622 and 632 at both ends of the first and second camshafts 620 and 630 so that the pair of first and second camshafts 620 and 630 are rotated in opposite directions.

 To describe the rotation direction of the pair of first and second camshafts 620 and 630, the left first camshaft 620 is rotated counterclockwise and the right second camshaft 630 is rotated clockwise . At this time, since the two camshafts 620 and 630 forming the pair are inclined downward by the progress of the aggregate like the screen 400, they are bound to the upper part and vibrated in the forward and backward direction. At this time, since the vibration frame 200 is vibrated in a state in which the main frame 100 is supported by a plurality of resilient and vibration absorbing members 300, vibration is not transmitted to the main frame 100.

When the vibration unit 600 is driven as described above, the first and second camshafts 620 and 630 move together with the vibration frame 200 by the amplitude generated by the vibration unit 600, And the drive cam 640 are connected to the first and second elastic members 670 and 680 around the hinge shaft 652. The endless belt 642 connects the first and second cam shafts 620 and 630 to the drive motor 640, So that the driving force of the driving motor 640 is surely transmitted to the first and second camshafts 620 and 630 of the vibration unit 600.

In the state in which the vibration frame 200 is driven and vibrated by the vibration unit 600 as described above, the mixture in which the aggregate and the washing water are mixed is continuously supplied to the screen 400, which is one upper portion of the vibration frame 200.

When the mixture is supplied onto the screen 400, the coarse aggregate of 5 mm or more is not allowed to pass through the screen 400, and the washing water and a part of fine aggregate of 5 mm or less are passed through the screen 400, 500, and the mixture containing the fine aggregates that have fallen on the dewatering screen 500 can not pass through the fine aggregate of 0.8 mm or more by the dewatering screen 500 and the washing water and a part of the fine sludge of 0.8 mm or less are passed, And falls to the hopper 110.

In this state, since the vibration frame 200 is also continuously vibrated, selection and dehydration are started through the screen 400 and the dewatering screen 500.

The vibration frame 200 is rotated in opposite directions to each other as shown in Fig. 15, and the first and second cam shafts 620 and 630 and the first and second cam-gears 622 and 632, which constitute the vibration unit 600, (a), (b), (c), and (d) sequentially and continuously. When the first and second camshafts 620 and 630 and the first and second cam-gears 622 and 632 are rotated, the force starts to coagulate in the state of FIG. 15 (b) The cohesive force of the force reaches the maximum at the point of time when the vibration frame 200 becomes a vibration point, and acts as a vibration point at which the vibration frame 200 vibrates (see a virtual line arrow shown in Fig.

In other words, each time the eccentric cams of the first and second camshafts 620 and 630 reach the vibration point that is opposed to each other before reaching the top dead center, the coarse aggregate on the screen 400 and the dewatering screen 500, The fine aggregate on the upper right side is bounded in the oblique direction.

After the vibration frame 200 is bound as described above, the cohesion force is released when it is rotated to the position (d) in FIG. 15, and the rotation start position is rotated to the position (b) The vibration of the vibration frame 20 is repeatedly generated continuously.

Since the cam-angles of the pair of first and second cam shafts 620 and 630, the mounting angle of the housing 610, and the center of gravity of the vibration frame 200 are balanced and organically coupled, So that the coarse aggregate and the fine aggregate on the screen 400 and 500 are evenly bounded so that the dehydration of the aggregate is ensured as well as the dehydration of the aggregate is ensured. .

As a result, the coarse aggregate on the screen 400 and the fine aggregate on the dewatering screen 500 are slightly advanced to the other side of the screen 400 and the outlet side of the dewatering screen 500 whenever jumping occurs. More specifically, the eccentric portions of the first and second camshafts 620 and 630 and the first and second cam-gears 622 and 632 are bounded before reaching the top dead center at the bottom dead center, The force for bounding is extinguished so that the forward and backward force is generated to move in the forward and backward directions.

The first and second camshafts 620 and 630 of the vibration unit 600 according to the present invention are arranged in the order of 2 (2) and 6 (4), assuming that the amplitude generated by one camshaft is oscillated only in the forward and backward directions, The amplitude of the vibration in the forward and backward directions is reduced to about half of that of the conventional vibration unit having one camshaft, that is, about 6 to 7 mm.

Since the amplitudes in the forward and backward directions are reduced to half as compared with those of the conventional screening apparatus, the residence time of the aggregate in the screen 400 and the screen 500 is increased. Thus, the residence time of the aggregate is increased, Zooming improves the ability to sort and dewater the aggregate.

Since the sorting screen 400 is inclined downward toward the discharge side even when the amplitude of the vibrating frame 200 is small, the coarse aggregate on the sorting screen 400 can be sorted smoothly and reliably without being accumulated on the sorting screen 400, The fine aggregate on the dewatering screen 500 is bounded by the dewatering screen 500 and is shifted in the diagonal direction, i.e., the upper front side of the draining side, by the amplitude, even though the dewatering screen 500 is inclined upward toward the discharge side, The fine aggregate is also reliably dewatered without causing the droplet phenomenon to occur in the dewatering screen 500, and the screening and dewatering ability is improved.

As described above, according to the present invention, the upper screen screen 400 of the vibration frame 200 is provided, and the dewatering screen 500 is integrally provided at the lower portion thereof, It is possible to perform complex, batch, and efficient operations in the apparatus of the present invention, thereby minimizing occupancy space and operating costs of the apparatus.

The washing water and the sludge having passed through the screen 400 and the dewatering screen 500 of the vibration frame 200 are collected in the tank hopper 110 inside the main frame 100, When the circulating water pump 130 is operated, the wash water in the tank hopper 110 is lifted through the discharge pipe 120 and sent to the water tank (not shown) through the discharge box 140 Or may be supplied to the screen 400 on the vibration frame 200 for circulation.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It can be transformed.
