Description

A vibration screen to induce distribution of aggregates}

The present invention relates to a vibrating screen that uses a screen plate divided into two or more sections having different inclination angles to prevent pile-up of supplied aggregate and induces efficient dispersion and sorting.

BACKGROUND OF THE INVENTION Waste generated from construction sites is rapidly increasing due to construction works such as dismantling buildings for redevelopment projects or remodeling old buildings. In addition, as the reconstruction of old buildings is actively progressing, the generation of construction waste is continuously increasing, but there is a lack of space and facilities to treat it, and wastewater and sludge generated from stacked waste cause soil and water pollution. There is a problem with

Accordingly, construction waste generated from construction sites was stipulated to be treated according to the ‘Act on the Promotion of Recycling of Construction Waste’. In order to minimize environmental pollution, substitute resources, and promote cost reduction by recycling construction waste through an appropriate process, various methods for recycling construction waste are proposed in related industries. In particular, the method of using construction waste as recycled aggregate through the process of crushing and grinding is widely used as a construction waste recycling method. do.

Vibration sorters are used for the purpose of separating aggregates by particle size, or are used in the work of filtering aggregates by particle size from construction waste as described above.

In general, a vibratory sorter is a device that separates aggregates according to the size of particles according to vibration by having a vibration motor that generates vibration and a sorting unit on top of the vibration. There is an inclined screen soil sorter and sorting method that eliminates clogging. This technology is a plate-shaped base plate seated horizontally on the ground and a screen net obliquely placed on top of it to relieve the retinal force of the screen, physically pressurizing soil and foreign substances attached to the gaps in the screen net to forcibly remove them. It is configured to include a cleaning means. It is configured to effectively relieve clogging of the screen net without damaging the screen net by moving in a straight line from the lower side of the frame where the screen net is installed, but it is viscous due to the same inclination angle from the moment the aggregate is supplied to the bottom. Or, in the case of tightly packed aggregate, it is difficult to separate effectively.

In addition, the registered patent No. 10-1684899 “vibration sorter with mesh screen tension control device” is configured so that the user can easily adjust the tension of the mesh screen. The patent allows the user to adjust the tension of the mesh screen as needed to manage the tension as needed, and has advantages such as extending the lifespan of the mesh network, but similarly, the slope of the mesh screen is constant, so aggregate aggregates that are not separated from the top can be transported to the bottom in a lumped state. In addition, the tension of the mesh screen is adjusted to increase the efficiency when the movement and sorting efficiency of the aggregate is reduced. Since the user needs to check the vibrating sorter and adjust the tension of the mesh screen, it is sufficient to operate the device. Low efficiency compared to other devices.

Therefore, there is a need for a technology capable of effectively separating viscous and tightly aggregated aggregates even when supplied, and capable of quickly transporting the aggregates without stagnation without the user's manual work.

In order to solve the above problems, the present invention is "a vibrating screen having a certain width and length and sorting the grain size of the aggregate 10, divided into two or more sections with different inclination angles, and a screen plate made of an inclined surface on which a separation network is formed ( 100), and the screen plate 100 has the highest slope in the uppermost section 110 compared to other sections, so that the aggregate 10 supplied to the top of the screen plate 100 is the uppermost section 110. ) provides an aggregate dispersion induced vibrating screen, characterized in that it is configured to be relatively quickly transported to prevent accumulation of the aggregate 10.

Hereinafter, the present invention will be described in more detail through examples. Since these examples are intended to illustrate the present invention only, the scope of the present invention is not to be construed as being limited by these examples.

Hereinafter, the present invention will be described in detail in conjunction with the accompanying drawings.

In addition, the top, bottom, left, and right sides of the drawing shown in [Figure 1] are applied to the claims of the present invention and described, but the uppermost section 110 of the screen board 100, which is located on the right side and has the highest inclination compared to other sections, is placed at the top , and the section located on the left and having a gentle slope compared to other sections is referred to as the lower section. In addition, the screen plate 100 refers to a portion visible in the drawing as a front side and a rear portion as a rear side.

The example of the direction set above is set to help understanding of the present invention, and the standard of the direction may be relatively changed according to the situation.

Hereinafter, embodiments of the present invention will be described based on the direction set above.

1 shows a state in which the side plate of the screen plate 100 is cut.

The screen plate 100 is divided into two or more sections, and each section may be formed with a different inclination angle. The screen plate 100 has a certain width and length. In this case, the moving direction of the aggregate 10 is referred to as the longitudinal direction of the screen plate 100, and the direction orthogonal thereto is the width direction of the screen plate 100. is called

In addition, the screen plate 100 is formed of a separation network, and the separation network may be composed of a mesh network made by weaving metal yarns, resin yarns, fiber yarns, etc., or a perforated network in which a plurality of perforations are formed in a metal plate.

The mesh network is made of a dense mesh, and depending on circumstances, a mesh network standard suitable for the size of particles to be classified may be applied.

The perforated network is separated according to the size of the perforated hole and the shape of the perforated hole, and typically a perforated network made of perforated holes such as circle, crowbar, square, seagull, long hole, embossing, wind, check model can be applied.

As shown in [Fig. 1], the uppermost section 110 of the screen plate 100 may be formed with a higher inclination than other sections.

Therefore, the aggregate 10 supplied to the upper portion of the screen plate 100 is transferred relatively quickly from the upper portion, so that the aggregate 10 does not accumulate in the input unit and can be rapidly transferred downward. In particular, in the case of aggregate 10 combined with viscous sludge, it is highly likely to be attached to the inclined surface of the screen plate 100, hinder the transfer of other aggregates 10, and cause accumulation. However, in the screen plate 100 of the present invention, the uppermost section 110 is configured with a high inclination to separate the highly viscous aggregate 10 from the screen plate 100 to prevent accumulation of the aggregate 10. can

In addition, when the screen plate 100 includes a plurality of sections other than the uppermost section 110, the inclination angle of the screen plate 100 may become gentler from the top to the bottom.

A plurality of sections other than the uppermost section 110 of the screen board 100 may be added with a relatively gentle slope compared to the uppermost section 110 .

[Fig. 1] and [Fig. 2], the section located below the uppermost section 110 and having a relatively gentle slope is set as the middle section 120a, and is located below the middle section 120a and has a relatively gentle slope. An example in which the most gentle section is set to the lower section 120b is shown.

Referring to the transfer state of the aggregate 10 in each section based on the above embodiment, when the aggregate 10 is supplied to the screen plate 100, the upper part of the screen plate 100 has a high slope due to the aggregate ( 10) can be transported downward at high speed.

The aggregate 10 transported to the next section, the middle section 120a, is transported to a slope with a moderate inclination, and the conveying speed is reduced, so that sufficient time for sorting the aggregate 10 is secured in the middle section 120a. It can be.

Finally, the aggregate 10 passing through the middle section 120a is further reduced in feed rate while the aggregate 10 moves to the lower section 120b having the most gentle slope, and finally in the lower section 120b. Before the aggregate 10 is discharged, the aggregate 10 that has not yet been screened in the interruption section 120a may be more precisely screened.

The above embodiment is an embodiment in which the screen board 100 is formed of three sections, and if more detailed classification is required, the screen board 100 may be configured by additionally dividing the sections.

In addition, the screen plate 100 may be configured such that steps 130 are formed for each section.

Referring to FIG. 2 , the screen plate 100 may be arranged such that a step 130 is formed for each section having a different inclination. At this time, the aggregate 10 supplied to the upper part of the screen plate 100 is transferred to the lower part along the inclined surface of the screen plate 100, and when the aggregate 10 reaches the step 130 formed for each section, the step ( As the aggregate 10 rapidly falls in 130, a stronger impact force may be added to the aggregate 10.

In the case of the embodiment of [Fig. 2], a step 130 is formed for each section, and an impact force is applied whenever passing through each step 130, so that the dispersion of the aggregate 10 can be more effectively induced. This can act in combination with the vibration force applied to the screen plate 100 to increase the scattering and falling kinetic energy of the aggregate 10, thereby dispersing the aggregate 10 more effectively. In addition, since the aggregate 10 is effectively dispersed as described above, misclassification is reduced during particle size screening, and the probability that the aggregate 10 is discharged in an unclassified state can be reduced.

In addition, the screen plate 100 may be detachable and replaceable for each section.

When the screen plate 100 vibrates the heavy aggregate 10 up and down and the collision of the aggregate 10 is applied for a long period of time in the process of transporting, the classification network of the inclined surface may be worn or damaged.

Therefore, the inclined surface of the screen plate 100 is modularized for each section and configured to be detachable for each section, enabling separation and replacement to facilitate the repair of the screen plate 100 and reduce the time required for maintenance and repair. can reduce cost.

In addition, the screen plate 100 may be composed of a plurality of layers for each section or the entire section. A separate screen plate 100 is additionally provided under the installed screen plate 100 for all sections or sections, so that the sorted and filtered aggregate 10 can be re-sorted as necessary to perform more detailed sorting work.

In addition, a protruding jaw 140 installed in the width direction of the screen plate 100 may be further included.

This will be explained with reference to [Figure 3].

The protruding jaw 140 may be installed in any part of the entire section of the screen plate 100 in the width direction. In the protruding jaw 140, the aggregate 10 is transported from the upper part to the lower part, and the aggregate 10 collides with the protruding jaw 140 and scatters, and in the process of falling, the aggregate 10 effectively moves the screen plate 100. Its purpose is to disperse upward and increase the sorting efficiency of the aggregate 10.

The protruding jaw 140 has an excellent aggregate 10 dispersing effect by itself, but when it acts in combination with the step 130, the aggregate 10 dispersing effect is further increased, and (b) of [FIG. 4] Refer to for further details.

When the aggregate 10 is supplied to the top of the screen plate 100, the transport speed of the aggregate 10 increases in the uppermost section 110 and collides with the protruding jaw 140 or the step 130. It is carried out through a drop-and-collision process. When the screen plate 100 consists of a plurality of sections, the aggregate 10 is dropped and collided by the step 130 provided on the boundary surface of each section and the protruding jaw 140 disposed on the inclined surface of the screen plate 100. , scattering, etc. are passed through until it reaches the bottom, and the aggregate 10 that has reached the bottom can be evenly dispersed and distributed on the screen plate 100.

In addition, the protruding jaw 140 may be configured to be installed along the entire length or a partial length of the screen plate 100 in the width direction.

In addition, a plurality of protruding jaws 140 may be configured to be distributed.

This will be described in detail with reference to [Figure 5].

The protruding jaw 140 can lead to optimal efficiency by directly installing the protruding jaw 140 at a desired location and a desired length according to the physical characteristics of the supplied aggregate 10 and the process of sorting and separating. there is.

For example, when aggregates 10 that are relatively strongly aggregated or are not easily separated due to high viscosity are supplied, a more active dispersing effect can be induced by installing the protruding jaws 140 more densely.

In addition, the protruding jaws 140 may be continuously installed in a partial length or arranged in a zigzag pattern, as shown in FIG. 5 . In particular, when the protruding jaw 140 is installed in a zigzag pattern with a partial length, the aggregate 10 collides with the protruding jaw 140 without missing, and the collided aggregate 10 collides again and scatters when it descends, and the process of being scattered is repeated, effectively removing the aggregate. (10) is preferable because it can be dispersed.

In addition, the protruding jaw 140 is a member having a semicircular cross section, is installed on the inner lower part of the protruding jaw 140, and is connected to the cover 143 into which the spring 142 is inserted and one end of the spring 142. It further includes a hook 141, and pulls the hook 141 and hangs it on the side of the screen plate 100 or the separating net on the inclined surface, and the protruding jaw 140 is moved by the restoring force of the spring 142. It can be configured to be fixed to the screen plate 100.

This will be explained with reference to [Fig. 6].

The protruding jaw 140 may be formed of a member having a semicircular cross section and installed on the front surface of the screen plate 100 .

The cover 143 is installed on the inner lower part of the protruding jaw 140 and can insert the spring 142 therein. In addition, two covers 143 may be provided on both sides of the inner lower part of the protruding jaw 140 .

The spring 142 is provided to be inserted into the cover 143, one side is connected to the hook 141, and the other side may be coupled to the inside of the cover 143. In addition, the spring 142 may be formed of a tension spring 142 having a tensile restoring force.

This will be explained with reference to [Fig. 7].

When the hook 141 is pulled outward of the protruding jaw 140, it is connected to the spring 142 and can be variably changed in length, so that the side or side of the screen plate 100 is pulled by the required length. The protruding jaw 140 may be fixed by hanging on the separating net of the inclined surface.

For example, when the protruding jaw 140 is formed along the entire length of the screen plate 100 in the width direction, the hooks 141 provided on both sides of the protruding jaw 140 are hooked to the side of the screen plate 100, respectively. The protruding jaw 140 can be fixed to the screen plate 100, and hooks 141 provided on both sides of the protruding jaw 140 when the protruding jaw 140 is formed with a partial length of the screen plate 100 in the width direction. ) can be fixed by inserting it into the through hole of the separation network.

In the above, the present invention was examined in detail with specific examples. However, the present invention is not limited by the above embodiments and can be modified and modified within the scope without departing from the gist of the present invention. Accordingly, the claims of the present invention include such modifications and variations.
