JP6978031B2 - Residue recovery device with high water content - Google Patents

Description

The present invention relates to a recovery device capable of satisfactorily recovering a residue having a high water content that falls from a belt on the return side of a belt conveyor.

As is known, the carrier-side belt of the belt conveyor on which the conveyed object is mounted is inverted by the head pulley to become the return-side belt.

Then, the residue adhering to the surface (upper side) of the carrier side belt is on the lower side on the return side, so that the adhered residue falls on the travel path of the return side belt and is deposited on the travel path as the belt falls. do.

Since the accumulated fallen matter increases with the progress of operation, it is necessary to manually remove the deposited matter.

Therefore, a method is already known in which the deposit on the return belt is recovered as a residue (see, for example, Patent Document 1).

Utility Model Registration No. 3195653

By the way, in the conveyor equipment, in the rainy weather of the outdoor equipment, or in order to prevent the scattering from spreading, water is often sprinkled directly or indirectly on the transported material, and as a result, the water content of the transported material becomes very high. There are many.

Then, the amount of deposits adhering to the surface of the return side belt increases, and the amount of deposits deposited on the traveling path of the return side belt increases.

The deposit attached to the return belt is also a good raw material, and the residue deposited on the running path of the return belt is also a good raw material.

Therefore, the method of Patent Document 1 is adopted to efficiently return the residue due to adhesion to the carrier side belt, but the above-mentioned residue having a high water content is parallel to the main recovery conveyor and the sub recovery conveyor. When feeding while pinching between both belts, the pinching pressure between both belts is not constant over the entire length of the belt.

That is, since the parallel rollers are scatteredly arranged in the portion requiring the pinching pressure (range of the upper feed), the pinching pressure is not constant over the entire length between the portion where the rollers are arranged and the portion where the rollers are not arranged.

For this reason, the above-mentioned residue having a high water content has a significantly high fluidity, and therefore flows down at the time of top feeding.
Along with this flow, there was a problem that it was not delivered stably (efficiently).

Therefore, the present invention is to recover the residue having a high water content by feeding the residue while pinching it extremely stably even if the residue has a high water content.

In order to solve the above problems, the present invention provides a cleaning means for removing surface deposits on the return-side belt inverted by the head pulley in the belt conveyor, and receives the residue of the removed deposits. As described above, the tail-side horizontal portion crosses under the return-side belt of the conveyor, the intermediate portion extends upward from the horizontal portion, and the head portion continuous from the intermediate portion is a residue on the carrier-side belt of the belt conveyor. A main recovery conveyor having a horizontal portion on the head side is provided, and the carrier side overlaps the carrier side of the main recovery conveyor in the middle portion of the carrier side belt of the main recovery conveyor and the horizontal portion on the head side to form the belt conveyor. A sub-recovery conveyor for discharging the residue is provided, and a plurality of forcedly driven rotating bodies are provided at the dotted positions in the belt traveling direction on the back surface of the main recovery conveyor and the sub-recovery conveyor on the back surface of the residue holding carrier, and the rotation thereof is performed. A configuration in which a pressurizing body is provided at a plurality of equidistant positions on the peripheral edge of the body so as to abut on the back surface of the carrier-side belt of the main recovery conveyor and the sub-recovery conveyor and bend the carrier-side belt in a continuous wavy shape as the carrier-side belt is extruded. adopt.

In addition, a cleaning means for removing surface deposits on the return-side belt inverted by the head pulley in the belt conveyor is provided, and the horizontal portion on the tail side is the return of the conveyor so as to receive the residue of the removed deposits. A main recovery conveyor having a head-side horizontal portion that crosses under the side belt, is continuous from the horizontal portion, and an intermediate portion extends upward, and a head portion that is continuous from the intermediate portion has a head-side horizontal portion that returns a residue to the carrier-side belt of the belt conveyor. In addition, a secondary recovery conveyor is provided in the middle portion of the carrier side belt of the main recovery conveyor and the horizontal portion on the head side so that the carrier side overlaps the carrier side of the main recovery conveyor and discharges the residue to the belt conveyor. Furthermore, the travel of the main collection conveyor and at least one of the residues pinching carrier side rear surface side heights and endless parallel Nijo with drive function which travels between can Yariya side is above the low-income belts sub-recovery conveyor Rutotomoni provided body, also possible to use a construction in which a pressure body to bend extruded belt from the carrier side to the continuous wave the length dotted position of the running body.

As described above, according to the residue recovery device having a high water content of the present invention, the deposits adhering to the belt of the belt conveyor are removed by the cleaning means, and the removed residue is removed from the horizontal portion on the tail side of the recovery conveyor. Then, the residue (adhesion) is transferred while being sandwiched between the belts on both carrier sides of the main recovery conveyor and the sub recovery conveyor, and returned from the horizontal part on the head side of the sub recovery conveyor to the carrier side of the conveyor. Therefore, there is an inconvenience that the residue falls on the return side of the conveyor and requires recovery work, and even the residue is a good raw material, and if it can be recovered, it has a peculiar effect that it can be sufficiently reused.

When the moisture content of the residue to be fed while being sandwiched between the carrier side of the main recovery conveyor and the sub recovery conveyor is high , the carrier side belt is strongly pressed by each rotating pressurizing body to significantly reduce the pinching pressure. Since it is improved, there is a peculiar effect that even a residue having a high water content can be stably fed while maintaining an extremely good pinching pressure without flowing down between the belts on both carrier sides.

In particular, since the carrier-side belt bends in a continuous wave shape due to the pressing by the pressurizing body, there is also an effect of suppressing the flow.

Further, it is provided at the scattered position of the endless traveling body with a drive function provided on the back surface side (between a high place and a low place) of at least one return side belt of the main recovery conveyor and the sub recovery conveyor. since the pressure body Debe belt are to be pressed, it is possible to significantly improve the gripping force of the residue.

Therefore, even a residue having a high water content can be well sandwiched between the belts on both carrier sides, and has a peculiar effect of suppressing the flow between the belts while maintaining a stable top feed, and the pressurized body has a peculiar effect. It is also possible to prevent the belt from flowing down by continuously bending the belt with the pressurization of.
