Description

Ejin-dong Dry Gravity Separator

The present invention relates to a screening device, and more particularly, to an aged copper specific gravity screening device capable of improving the screening efficiency of a mixture of heavy and light particles.

Ejin-dong dry specific gravity screening device is a device that selects and discharges mixtures with different specific gravity.

In the conventional Ejindong dry gravity screening device, a mesh-type sorting deck is inclined on the upper portion of the main body provided from the blower, and the sorting deck receiving the vibration generated by the motor is vibrated by a suspension means such as a spring. Supported.

Then, the air generated by the blower rises and affects the mixture placed on the sorting deck. Therefore, the mixture is not only affected by the air flow of the rising air, but also by the vibration, and has a structure that is selected and discharged by specific gravity from the sorting deck.

However, in the conventional Ejin copper dry specific gravity screening apparatus, since the moving directions of the heavy particles (large specific gravity) and the light particles (small specific gravity) are the same, they are often mixed with each other and thus have a problem in that the screening efficiency is lowered.

The present invention has been made in order to solve the above problems of the prior art, by varying the movement path of the heavy particles and light particles by pleating the mesh table on which the selection object is placed, thereby mixing the heavy particles and light particles The purpose is to provide an erected copper dry gravity screening device that can increase the sorting efficiency by minimizing.

The Ejin copper dry specific gravity screening apparatus according to the present invention is for selecting and discharging a mixture of particles having different specific gravity, that is, a mixture of heavy particles (large specific gravity particles) and light particles (small specific gravity particles) by specific gravity. 100, a main body 200 receiving air from the blower 100, a sorting deck 300 installed on an upper portion of the main body 200, and a vibration providing vibration to the sorting deck 300. It comprises an application unit 400, and a hopper 500 for supplying the mixture to the sorting deck (300).

The blower 100 is disposed on one side of the main body 200, and an air flow forming space formed inside the main body 200 through a flexible pipe P installed on one side of the main body 200. Provide air to 200a.

The main body 200 is formed in an empty housing shape, and an airflow forming space 200a is formed therein. The vibration applying unit 400 is installed inside the main body 200.

The airflow formation space 200a serves to guide the air provided from the blower 100 to the upper side.

The sorting deck 300 is the frame 310, the perforated plate 320 installed on the frame 310, the air straight member 330 is installed on the upper side of the perforated plate 320, and the air straight member ( 330 is installed on the upper side of the mesh table 340, the cover 350 is installed on the upper side of the mesh table 340, the anti-dispersion cloth 360 connecting the frame 310 and the main body 200 It is composed of

The frame 310 is installed at an angle to the upper portion of the main body 200 inclined. The frame 310 is connected to the vibration applying unit 400 receives a vibration force from the vibration applying unit 400.

The perforated plate 320 is a metal panel in which a plurality of perforation holes 321 are formed at predetermined intervals, and is installed above the frame 310, that is, below the air straight member 330.

The air straight member 330 is installed on the upper side of the perforated plate 320, that is, the lower side of the mesh table 340, and the air supplied from the blower 100 and passed through the airflow forming space 200a It serves to rise in the vertical direction with respect to the mesh table 340. That is, the air straight member 330 is installed in the space formed between the perforated plate 320 and the mesh table 340, and the air flowing toward the mesh table 340 through the airflow forming space 200a is Straightness is improved through the air straight member 330.

If the air flow forming space 200a of the main body 200 is formed in a wide conical shape, the air may be inclinedly supplied to the mesh table 340. In this case, the air may pass through the air straight member 330. The flow of photographic air is converted and supplied in a direction perpendicular to the mesh table 340. Therefore, since the air having improved straightness is supplied to all points of the mesh table 340, the sorting efficiency can be further increased.

The air straight member 330 as described above is made of a synthetic resin material, it is made in such a form that can raise the air in a straight line, such as a honeycomb structure continuously connected or a cylindrical structure continuously connected. It is considered to be preferable to manufacture the honeycomb structure in consideration of structural stability and the like.

The mesh table 340 is installed above the frame 310, more specifically, above the air straight member 330, and is rotatably installed on the perforated plate 320 by hinge coupling. Since the frame 310 is installed to be inclined, the perforated plate 320 and the air straight member 330 are also installed to be inclined, and as a result, the mesh table 340 is also installed to be inclined.

The air introduced through the airflow formation space 200a is passed from the lower side to the upper side. In other words, the mesh table 340 is completed by arranging the wires of steel material at regular intervals in the horizontal direction and spaced apart at regular intervals in the longitudinal direction, such as a method of weaving the warp and weft of the textile fabric. It is manufactured by crossing steel wire in the transverse direction and the longitudinal direction.

When the mesh table 340 is described in more detail, the mesh table 340 is a place where a mixture to be sorted is placed on an upper surface, and is formed integrally with the wrinkle part 341 and the wrinkle part 341. It consists of the flat part 342.

The wrinkle portion 341 is a portion through which the mixture is supplied through the hopper 500, and a plurality of wrinkles are formed therein, and the valley portion 341a and the peak portion 341b are continuously repeated.

The valley part 341a is the lowest part of the corrugation part 341, and a particle having a high specific gravity moves in the valley part 341a toward the flat part 342 upward. Therefore, the particles having a high specific gravity move to the flat portion 342 quickly along the valley portion 341a because the particles having a specific gravity move linearly through the valley portion 341a without riding over the hill portion 341b.

The peak portion 341b is a portion having the highest height in the wrinkle portion 341. Since the particles having a small specific gravity in the mixture pass through the peak portion 341b, the moving speed of the particles having a small specific gravity is along the valley portion 341a. The moving specific gravity is relatively smaller than the moving speed of large particles.

As described above, the particles having a large specific gravity move toward the flat portion 342 along the valley portion 341a, and the particles having a relatively small specific gravity pass over the mountain portion 341b. The direction of movement is nearly vertical. Since the moving directions of the large specific gravity particles and the small specific particles are clearly distinguished, the sorting efficiency of the large specific gravity particles and the small specific gravity particles is greatly improved.

On the other hand, the height of the wrinkle portion 341 is gradually lower toward the flat portion 342. That is, the height of the peak portion 341b gradually decreases toward the flat portion 342, and the depth of the valley portion 341a becomes shallower. In this way, particles having a high specific gravity moving along the valley portion 341a may naturally move toward the flat portion 342.

Since the flat part 342 is not wrinkled unlike the wrinkle part 341, the ridge part 341b and the valley part 341a are formed flat without being formed.

Since the mesh table 340 is formed to be inclined, the wrinkles 341 and the flat part 342 are also formed to be inclined, and the flat part 342 is positioned at a relatively higher position than the wrinkles 341. .

The cover 350 is installed on an upper surface of the mesh table 340. The cover 350 is provided with an outlet 380.

The dispersion preventing cloth 360 connects the upper end of the frame 310 and the main body 200 to prevent the air from being dispersed to the side. Since the air generated in the blower 100 must be supplied to the mesh table 340 without leaking to increase the sorting efficiency of the mixture, the dispersion preventing cloth 360 may surround the upper edge of the main body 200 and the frame 310. Isolate the outside of the border from the outside.

Meanwhile, a ripple 370 is installed in the mesh table 340.

The ripple 370 may include a coupling part 371 disposed on the mesh table 340, a vertical part 372 integrally formed with the coupling part 371, and an upper end of the vertical part 372. It consists of a horizontal part 373 which extends horizontally and integrally.

The coupling portion 371 may be located at the valley portion 341a, and a bottom surface thereof may be fixed to the valley portion 341a, or one end thereof may be fixed to an edge wall of the cover 350. The height of the coupling portion 371 is to be different depending on the size and specific gravity of the light weight of the object to be selected, 1 to 5 times the size of the light weight is appropriate.

The vertical portion 372 is erected at a predetermined height upward from the end of the coupling portion 371. The height of the vertical portion 372 should have a height that can prevent the discharge of light weight toward the horizontal portion 373 without interfering with the discharge of heavy weight of the object to be selected, 2 to 6 times the size of the heavy weight About twice as much. And the length of the horizontal portion 373 is adjusted according to the volume ratio of the light and heavy. For example, when the weight content is 30%, it is appropriate to make the length of the horizontal portion 373 equal to 30% of the total length of the ripple 370.

The horizontal portion 373 extends horizontally in the direction opposite to the wrinkle portion 341 at the upper end of the vertical portion 372. Therefore, an empty space is formed between the lower end of the horizontal portion 373 and the flat portion 342. Particles having a large specific gravity pass through the empty space between the horizontal portion 373 and the flat portion 342, and particles having a relatively small specific gravity float upward by the air supplied to ride on the upper end of the coupling portion 371. Go beyond. Therefore, the movement of particles having a large specific gravity blocked by the coupling portion 371 is limited, and the movement of particles having a small specific gravity blocked by the horizontal portion 373 is limited.

The end of the horizontal portion 373 may be fixed to the edge wall of the cover 350. That is, by fixing one end of the coupling part 371 to the edge wall of the cover 350 and the end of the horizontal part 373 to the opposite edge wall of the cover 350 to which the coupling part 371 is fixed, the ripple 370 is to be firmly fixed.

The vibration applying unit 400 is to provide vibration to the sorting deck 300, it is installed in the lower portion of the sorting deck (300). The vibration applying unit 400 vibrates the sorting deck 300 inclined left and right so that the mixture of the upper surface of the mesh table 340 moves toward the outlet 380.

The hopper 500 supplies the mixture to the upper surface of the mesh table 340 of the sorting deck 300.

The present invention relates to an Ejin copper dry specific gravity screening apparatus, which can be used in environmental projects and recycling industries to prevent environmental pollution and efficiently utilize resources.
