Description

Screen structure of waste sorting device {WASTE SELECTOR'S SCREEN STRUCTURE}

The present invention relates to a structure of a screen used for a waste sorting machine, and more particularly, to a screen structure of a waste sorting device having a sieve hole formed on a plate of rubber material and attached to a cylindrical or flat screen support frame. will be.

Waste sorting device is a device for separating recyclable or landfillable by-products such as soil or aggregate contained in garbage or construction waste. It is used in construction sites and landfills as a device for separating soil and aggregates from incineration trash or landfills by passing through them.

In such a waste sorting device, the screen structure plays a decisive role in the sorting efficiency, and a screen having a structure in which a mesh is formed by weaving iron bars in a grid form on a support frame of a screen composed of a cylindrical or plate type is generally used. There was a problem.

That is, since both cylindrical and flat screens are used in direct contact with highly corrosive wastes, they are easily rusted and have a very short lifespan. Since the mesh is manufactured by welding thin steel bars in the form of lattice, it takes a lot of time and effort to manufacture. In most cases, the screen should be replaced by a cylinder even in partial wear. there was.

In particular, the waste contains moisture and clay-based soil together, and after the operation, they cling to the screen and close the net, so the sorting efficiency is drastically reduced.In order to remove the waste, the screening operation must be cleaned after stopping the operation. Frequently interrupted problems had.

On the other hand, in order to prevent the net from being closed, in the case of a cylindrical screen, a flamethrower is installed and reciprocated through the cylindrical side to prevent entanglement caused by moisture. Incineration also burns trash that emits toxic gases, contaminating the atmosphere.

The present invention can be applied to both flat screens and cylindrical screens constituting the waste sorting device, and can be easily assembled or replaced by attaching them on a support frame divided at regular intervals. By presenting a new screen structure of the configuration so that tangling is fundamentally blocked, it is intended to solve the problems of the conventional screen structure.

To this end, the present invention proposes a screen structure of a waste sorting device having a structure in which a rubber screen plate having a sieving hole is formed on a rubber plate and attached to a lattice space divided at predetermined intervals of a support frame.

The present invention constitutes a screen applied to a waste sorting apparatus for separating the waste by sieving the input waste by size, the screen is composed of a support frame and a sorting unit installed in the support frame to perform a sieving function, the sorting unit Rubber with a configuration in which a plurality of sieve holes are formed on a rubber plate in the lattice-shaped space to form a space divided into a lattice by the horizontal member and the vertical member so as to be integral with the support frame. It is characterized by comprising a structure to which the first screen plate is attached.

The screen includes a screen applied to a sorting device using a cylindrical screen or a sorting device using a flat screen, and is divided according to the shape of the supporting frame. The supporting frame is an element for maintaining the skeleton of the screen. In this case, it is made of a cylindrical shape, roller supports are formed at both ends in the form of a circular frame, and a sorting part is formed in the body portion between the two roller supports, and a chain gear is formed at one of the roller supports to be mounted on the waste sorting device. Is rotated by the power transmitted through the chain gear in the supported state. In the case of the flat screen, the support frame is formed of a rectangular frame, and a sorting part is formed inside the frame, and the frame is oscillated. It is configured to be applied.

The sorting portion formed on the flat screen or the cylindrical screen is formed in the support frame, and forms a grid-like space using a horizontal member and a vertical member integrally formed with the support frame, and a rubber strip plate on the space. The rubber screen plate is a rigid rubber material and is sized so as to cover the space partitioned by the horizontal and vertical members of each support frame, and is formed in the interior of the sieving hole at a predetermined interval.

The screen of the rubber screen plate is fixed by bolts or rivets with its edges in contact with the horizontal and vertical members to complete the screen constituting the waste sorter.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIGS. 1 and 2 are embodiments in which the present invention is applied to a cylindrical screen, and the cylindrical screen (a) is formed of a support frame and a sorting part. The frame 10 has roller support members 11 formed at both ends in the form of a circular frame, and a chain gear 12 is formed at one side of the roller support, and a sorting part is formed in the body part. A lattice-shaped space is formed by a horizontal member 13 connecting the support members at regular intervals and a vertical member 14 having a circular frame shape which binds the horizontal members at regular intervals, and the space constitutes the attachment portion 15. The rubber screen plate 30 is attached to each attachment portion. The supporting frame is generally cylindrical by the horizontal member and the vertical member, and the number of horizontal and vertical members of the screen is increased. In general, it is composed of 6-8 horizontal members and vertical members so that the horizontal members can be divided into 3-4 equal parts to maintain the cylindrical skeleton along the sidewalls of both roller supports. Each of the horizontal and vertical members is integrally welded with both roller supports to form a frame.

In case of the horizontal member, it is possible to use a structure of attaching a ring-shaped vertical member so as to contact the inside of both ends by using the “L” section steel so that the support frame of long length can exhibit sufficient strength against torsion. 3 may be configured to attach a ring-shaped longitudinal member inwardly using a “T” -shaped steel as shown in FIG. 3 to easily secure the attachment portion of the apparatus. FIGS. 4 and 5 show a flat screen. As shown in the embodiment to which the present invention is applied to (b), the support frame 20 includes a frame 21 formed in a rectangular shape and a sorting portion formed inside the frame. The member 22 and the vertical member 23 are formed in the frame so that the lattice space is formed by each of the transverse and longitudinal members 22 and 23, and the attachment portion formed by the lattice space. The rubber screen plate 30 is attached to the 24.

6 and 7 show an embodiment of the rubber screen plate 30 according to the present invention and have a configuration in which a sieve hole 31 forming a sieve net is formed in a rigid rubber plate having elasticity. The plate uses a rectangular rubber plate to cover the space in the form of a lattice, and the shape, size and spacing of the holes can be variously produced according to the type of garbage to be sorted.

The screen plate made of rubber material does not rust even when it is contacted by the corrosive substances contained in the waste, and as described below, the wave movement is performed by its elasticity to prevent the branching and the like from being entangled and closing the hole. It has an effect that can be done.

The sieve hole 31 formed in the sieve plate can be formed simultaneously with forming the screen plate, and can be formed by drilling a hole on the rubber plate, and the shape of the sieve hole hole is shown in FIGS. 6 and 7. As shown, it can be implemented in various forms such as round or square.

The rubber screen plate 30 is attached to the attachment portion 15, 24 of the cylindrical support frame 10 or the flat support frame 20 using fasteners 40 such as bolts and screws, It can be implemented in a structure in which the fastening hole 40a is formed in advance so that attachment by fasteners can be easily made to each edge of the rubber screen plate.

As shown in FIG. 8, the screen structure is attached to and fixed only on the horizontal and vertical members of each screen plate as shown in FIG. 8, and the middle part is free to maintain a flat or circular shape by the elasticity of the screen plate itself. It can be shaken by rotation or vibration.

Therefore, the clay containing moisture does not get stuck in the sieve hole, and even if it gets stuck, it is easily shaken off because it constantly vibrates during the screening operation.

Due to this operating principle, even in the case of garbage containing a lot of clay and moisture, there is almost no tangling, and continuous sorting operation is possible without interruption of work.

The vibration effect of the above-mentioned rubber screen plate is achieved even by the minimum vibration, and when the vibration width is too large, the screen plate rather hinders the screening and the shape deformation of the screen plate occurs. Preferably, the attachment portion formed by the horizontal member and the vertical member is also determined accordingly.

9 is a view illustrating a state in which the screen structure according to the present invention is applied to a cylindrical waste sorting apparatus, and the wastes filled in the hopper 50 are transferred to the conveyor belt 51 to be introduced into the cylindrical screen, and the thrown wastes are cylindrical. As it is discharged to the rear in accordance with the rotation of the small diameter of the aggregate and the earth through the hole of the screen is discharged to the outlet 53 of the lower portion of the main body 52, the aggregate discharged through the outlet is discharged conveyor (54) It is discharged to the outside, and garbage or thick wood chips are discharged to the rear of the cylindrical screen.

Reference numeral 55 in the drawing indicates the support of the waste sorter by a flat screen.

According to the present invention, by forming a sorting section using a rubber screen plate, the entanglement of rubbish is blocked by the elasticity of the rubber itself, and the screen is prevented from being closed, and the sorting efficiency is very high. As the screen is prevented from being corroded by the corrosive components contained in the garbage, the lifespan is longer than that of the conventional screen structure, and only the wear part can be replaced when worn, thereby reducing the maintenance cost. The screen structure according to the present invention forms a support frame in advance, and attaches a rubber screen plate formed in advance to a lattice-shaped space formed in the horizontal member and the vertical member of the support frame, respectively, to prepare a line for manufacturing the support frame and the rubber screen plate. The screen is assembled and manufactured as a result of different manufacturing and final assembly. Very simple and efficient manufacturing is possible.
