The present invention relates to an unsanitary landfill waste sorting apparatus including a rocking dispersion means, and more particularly, to separate the landfill wastes from each other when the landfill wastes can be sorted by incinerated flammable waste, renewable soil, and waste concrete. The present invention relates to an unsanitary landfill waste sorting device including a rocking type dispersion means to increase the sorting efficiency.

Construction waste concrete, rebar, wood, household waste, clothing, and waste vinyl that have been recycled for a long time have been buried in the ground because it is difficult to sort in terms of treatment technology and cost.

However, due to the high concentration of complex chemical leachate generated by landfill waste and the large amount of gases (CO, CO ₂ , CH ₄ , H _2, etc.) generated during the decomposition process of organic land microorganisms of landfill waste, Recently, technology for landfill waste treatment has emerged due to the development of residential land.

In the landfill waste sorting device according to the prior art, the landfill waste is usually sorted by inputting the trommel in the form of a perforated plate.

However, the landfill waste is mixed with non-combustible and incombustible materials such as earth and sand, concrete mass, brick and stone, and combustible materials such as vinyl cloth, wood chips, and clothing that are difficult to recycle and must be burned together. Therefore, the non-sanitary landfill waste sorting apparatus according to the prior art is not effectively screened.

Specifically, the landfill waste put into the hopper is transported to the trommel by the plate-shaped vibration feeder.Because the landfill waste has a high water content, feeding is difficult due to the vibration of the vibration feeder, and congestion occurs frequently. Since there is no proper structure to disperse the landfill waste is not dispersed at once and the trommel is blocked, there is a problem that the sediment screening is not made.

In addition, since the technology focuses only on sorting the landfill waste into soil and combustible waste without considering the removal of water contained in the landfill waste, there is a problem that the incineration efficiency is lowered as well.

The present invention is to solve the above-mentioned problems, to solve the problem of stagnation and sticking of landfill waste having a high moisture content to disperse and supply waste to the trommel, and to provide moisture before being supplied to the trommel The purpose of the present invention is to provide an unsanitary landfill waste sorting device that includes a rocking type dispersing means that can improve the sorting efficiency by removing.

In addition, another object of the present invention is to be able to prevent the malfunction of each device, as well as clogging the sorting hole by the landfill waste.

An unsanitary landfill waste sorting apparatus including the rocking type dispersion means according to the present invention provided to achieve the above object is a waste conveyance means for forcibly transporting the landfill waste having a high moisture content, the landfill waste supplied through the waste conveying means. Rocking type dispersion means for rocking and dispersing the waste, hot air drying means for drying the landfill waste dispersed by the rocking type dispersion means, and sorting means for sorting the landfill waste dried by the hot air drying means as soil and combustible waste. Characterized in that the configuration.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

As shown in Figure 1 and 2, the non-sanitary landfill waste sorting apparatus 100 including the rocking type dispersion means according to the present invention, the landfill waste (waste vinyl, household garbage, earth and sand, lightweight aggregate, rebars are mixed State, hereinafter abbreviated as " waste ", the hopper 110 into which the hopper 110 is introduced, the belt conveyor 120 for transferring the waste introduced into the hopper 110, and the waste supplied through the belt conveyor 120 can be incinerated. Trummel 130 for sorting the combustible waste and renewable soil, rocking dispersing means 140 for separating waste falling freely from the belt conveyor 120 to the trommel 130, rocking dispersion means 140 And a hot air fan 150 (shown in FIG. 2) for removing moisture by applying hot air to the waste separated through the through), and installed at the inlet side of the trommel 130 and passed through the oscillating dispersion means 140. Debt that selects aggregates over a certain size from waste Vibrating screen 160 consists of (as shown in FIG. 2).

As shown in Figure 1, the hopper 110 is a place where the waste is injected, the top and one side of the cylindrical shape for opening and discharging the waste.

As shown in FIG. 2, the belt conveyor 120 includes a driving drum 121, a driven drum 122, and a belt 123 that is wound around the driving drum 121 and the driven drum 122 and rotates in an endless track. The waste injected into the 110 is transferred to the trommel 130, which is a post process.

That is, the waste is separated through the rocking type dispersion means 140 before being supplied to the trommel 130 even if the various household waste, earth and sand, etc. are fixed in a lump form by moisture, and then dried by hot air to the waste. The clogging phenomenon of the trommel 130 can be prevented.

The trommel 130 is shown in detail in the 2004-117470 landfill waste sorting device patent application by the applicant, briefly described, because the waste has a high water content of the sorting hole at the time of passing the trommel 130 In order to minimize the blockage, the trommel 130 is formed of a mesh structure in which a plurality of rods having a circular cross section are combined in a lattice shape and a selection hole is formed therebetween. That is, since the rod has a circular cross section, waste does not adhere to the rod and slips, so that clogging of the sorting hole does not occur. The rod may be made of a SUS material that is not corroded by moisture of the waste.

In addition, the trommel 130 may be a single cylindrical structure or a dual structure in which trommels of different diameters are combined, and it is preferable to use a dual structure because the dual structure trommel can classify wastes.

 Although not shown in the drawing, the trommel 130 may be mounted inside the sealed case, and the high-pressure jet 170 may be further provided at the top.

As shown in Figure 3 and 4, the swinging dispersing means 140 is installed at a position lower than the discharge end of the belt conveyor 120 to separate the waste stuck to each other by rocking the waste falling from the belt conveyor 120 5, the swing chute 143 and the driving motor 144 which are rotatably mounted to the frame 141 installed below the discharge end of the belt conveyor 120 through the inner shaft 142. (Shown in FIG. 3), while being rotated by the rotational force of the driving motor 144 and eccentrically in the middle of the yaw inner shaft 145 and the yaw inner shaft 145 arranged in the width direction in the middle of the swing chute 143. One or more cams 146 may be configured to support the bottom of the swing chute 143 to swing the swing chute 143 by rotation of the inner shaft 145.

According to such a configuration, when the cam 146 rotates due to the rotational force of the drive motor 144, the swing chute 143 rotates about the inner shaft 142 during the rotation of the distal end due to the phase difference of the cam 146. By doing so, the waste dropped to the swing chute 143 is separated.

On the other hand, when the swing chute 143 oscillates, the cam 146 collides with a large impact energy and the cam 146 and the swing chute 143 are damaged within a short period of time. May be further employed. The buffer roller 147 is coupled to the cam 146 in the middle of the rotating shaft 148 which is arranged in the width direction at the bottom of the swing chute 143 so as to be idlingly mounted through the bearing, and is driven by the rotational force of the cam 146. While rotating, absorbs and attenuates the impact energy generated when the swing chute 143 swings.

The belt conveyor 120 rotates, and the swing chute 143 is a material of high strength and swings so that a gap is inevitably generated between the belt conveyor 120 and the swing chute 143. Since the waste falling from the conveyor 120 may escape the swing chute 143, the separation prevention plate 149 is employed. The release preventing plate 149 is an elastic material and is coupled to the swing chute 143 while the free end of one side is in contact with the belt conveyor 120 to fall from the belt conveyor 120 without interfering with the rotation of the belt conveyor 120. To induce the waste to be moved to the swing chute 143.

The swinging dispersing means 140 having the above-described configuration uses the drive motor 144 as the drive source, and the belt conveyor 120 also uses the drive motor as the drive source, so that the swing chute 143 can be used to reduce costs and simplify the structure. And the belt conveyor 120 share one drive motor 144 as a drive source. To this end, as shown in FIG. 3, the drive motor 144 drives the belt conveyor 120 through the reducer 144a (not an essential component, and is optionally used to minimize rotation of the inner shaft 145 during the yaw). The rotational force is transmitted to the drum 121, and the driving drum 121 is configured to transmit the rotational force to the inner shaft 145 during the yaw. Rotational force between each component is transmitted through a belt or the like.

As shown in FIG. 2, the heat blower 150 belts the air heated by the blower 151 forcibly blowing air, the heater 152 for heating the air blown by the blower 541, and the heater 152. It may be composed of a hot air spray pipe 153 for supplying the free fall from the conveyor 120 to dry the waste.

The fan-shaped vibrating screen is composed of a plurality of spokes arranged at a distance from each other and is installed at the lower end of the discharge end of the waste conveying means to sort wastes falling from the feeder by the size of the spokes by particle size. Since it is already known by the specific description will be omitted.

The operation of the unsanitary landfill waste sorting apparatus including the rocking type dispersion means according to the present invention configured as described above will be described.

Waste is introduced into the hopper 110 by heavy equipment or the like and transported through the belt conveyor 120. The belt conveyor 120 receives the driving force of the driving motor 144 and the belt 123 rotates to transfer waste, and at this time, the inner shaft 145 connected to the driving drum 121 of the belt conveyor 120. This rotation causes the swing chute 143 to swing by the rotation of the cam 146. Specifically, as shown in FIG. 4, when the upper dead center of the cam 146 rotates downward while the inner shaft 145 rotates, the inner shaft 145 rotates to rotate the cam 146. When the top dead center of the swing chute 143 is rotated counterclockwise through the inner shaft 142 for a time, and again the top dead center of the cam 146, the swing chute 143 is rotated clockwise . That is, one side of the swing chute 143 oscillates by reciprocating the free end of the other side in both directions with respect to the inner shaft 142 during the rotation. During the rocking motion of the rocking chute 143, the buffer roller 147 absorbs a shock between the rocking chute 143 and the cam 146, thereby reducing the wear of the parts and the impact noise.

Waste is dropped to the swing chute 143 through the belt conveyor 120, the separation prevention plate 149 coupled to one end of the swing chute 143 is elastically to the belt 123 of the belt conveyor 120 The waste does not leave the swing chute 143 without contacting and restraining the rotation of the belt 123.

The rocking chute 143 swings the waste while rocking as described above to disperse the wastes fixed to each other, and transfers them to the post process without congestion.

The waste dispersed while rocking by the swing chute 143 freely falls downward from the swing chute 143, and in this process, the waste is dried by removing moisture contained in the waste by the hot air blown by the hot air blower 150. .

Waste supplied by the swing chute 143 falls into the flat fan type vibration screen 160, and aggregates, for example, 100 mm or more of the waste, are sorted by the flat belt type vibration screen 160 to the lower belt conveyor 161. Aggregate and flammable waste of less than 100mm is supplied into the trommel 130.

The waste put into the trommel 130 is dispersed and dried by the rocking type dispersion means 140 and the hot air blower 150, and thus, the living garbage, earth and sand, lightweight aggregate, etc., which are stuck to each other by moisture, are separated from each other. When passing through 130, it is sorted by type (household garbage of 50 mm or more, aggregates of 30-50 mm or less, earth and sand of 30 mm or less). Domestic garbage, lightweight aggregate, earth and sand, and the like sorted by the trommel 130 are transferred to an incinerator, crushing facility, etc. through a transfer conveyor or temporarily loaded on the exit side of the trommel 130 for transportation. It can be transported by a vehicle, for example, combustible waste (living garbage, clothing, waste vinyl, etc.) is put into an incinerator and incinerated, and lightweight aggregate, earth and sand are recycled through separate treatment. Rebars are sorted by magnets and the like while being transported on a conveying conveyor with combustible waste.

As described above, according to the non-sanitary landfill waste sorting apparatus including the rocking type dispersion means according to the present invention, the landfill wastes are shaken during transport of the landfill wastes to disperse the landfill wastes that are stuck to each other by physical impact, By drying by preventing the congestion of landfill waste is prevented, the drying of the landfill waste is effectively effected to increase the sorting efficiency of the landfill waste and to prevent clogging of the trommel sorting hole.

As a result, since the selected soil and combustible waste are dried, most of the soil is selected from the combustible waste, and the incinerator is supplied with only the combustible waste that is purely incinerated, thereby reducing the fuel for incineration of the combustible waste and obtaining high quality soil. can do.

While the invention has been described and illustrated in connection with a preferred embodiment for illustrating the principles of the invention, the invention is not limited to the configuration and operation as such is shown and described. Rather, it will be apparent to those skilled in the art that many changes and modifications to the present invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes and modifications and equivalents should be considered to be within the scope of the present invention.
