Description

  The present invention relates to a recovery device that recovers well a residue having a high water content falling from a return side belt of a belt conveyor.

  As is well known, the carrier side belt of the belt conveyor carrying the conveyed product is reversed by the head pulley to become the return side belt.

  Then, the residue adhering to the surface (upper side) of the carrier side belt becomes the lower side on the return side, so that the adhering residue falls on the travel path of the return side belt and accumulates on the travel path as it falls. To do.

  Since the accumulated fallen objects increase with the progress of operation, it is necessary to remove the deposits manually.

  In view of this, there is already known a system in which the deposit on the return side belt is collected as a residue (see, for example, Patent Document 1).

Utility Model Registration No. 3195653

  By the way, in the case of conveyor equipment, when the outdoor equipment is raining, or to prevent the spread of scattering, water is often sprayed directly or indirectly on the transported object, resulting in a very high moisture content of the transported object. There are many.

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

  The adhering matter adhering to the return side belt is also a fine material, and the residue deposited on the return side belt is also a good material.

  Therefore, the method of Patent Document 1 is adopted so that the residue due to adhesion is efficiently returned onto the carrier side belt. However, the above-described residue having a high water content is used in parallel with the main recovery conveyor and the auxiliary recovery conveyor. When feeding while being clamped by both belts, the clamping pressure by both belts is not constant over the entire length of the belt.

  That is, because the parallel rollers are interspersed in the portions that require clamping pressure (upward feed range), the clamping pressure is not constant over the entire length between the roller arrangement portion and the portion where no roller is arranged.

For this reason, since the above-mentioned residue with a high water content has a considerably high fluidity, it will flow down during the upward feeding.
Along with this flow, there was a problem that it was not sent stably (efficiently).

  In view of this, the present invention is to recover a residue having a high moisture content by feeding the residue even if it is a moisture content having a high moisture content with very stable clamping.

  In order to solve the above-mentioned problems, the present invention provides a cleaning means for removing the surface deposit on the return belt reversed by the head pulley in the belt conveyor, and receives the residue of the removed deposit. The tail side horizontal part crosses under the return belt of the conveyor, the intermediate part extends upward from the horizontal part, and the head part continuous from the intermediate part puts residue on the carrier side belt of the belt conveyor. A main recovery conveyor having a head-side horizontal portion to be returned is provided, and the carrier side overlaps the carrier side of the main recovery conveyor in the middle portion of the carrier belt of the main recovery conveyor and the head-side horizontal portion, and the residue on the belt conveyor. Sub-collection conveyor is provided, and the main collection conveyor and the sub-collection conveyor are sandwiched To adopt a structure in which a pressure member of circumferentially interspersed arrangement such that rotational movement of the carrier side belt pressed while the same direction in the direction of belt travel dotted position of Yariya side backside.

  In addition, a cleaning means for removing the surface deposit on the return belt reversed by the head pulley in the belt conveyor is provided, and the tail side horizontal portion is loaded on the return side of the conveyor so as to receive the removed deposit residue. A main recovery conveyor having a head-side horizontal portion that traverses under the belt, the intermediate portion extends upward from the horizontal portion, and the head portion continuous from the intermediate portion returns the residue to the carrier-side belt of the belt conveyor. A sub-recovery conveyor for delivering the residue to the belt conveyor with the carrier side overlapped with the carrier side of the main recovery conveyor in the middle part of the carrier belt of the main recovery conveyor and the horizontal part on the head side; The back side of at least one residue holding carrier side belt of the main recovery conveyor and the auxiliary recovery conveyor An endless parallel two-strip traveling body with a drive function that travels upward on the back side of the carrier side between a high side and a low side is provided, and the clamping force of the return side belt is provided at the full-length scattered position of the traveling body The structure which provided the provision pressurization body of this may be employ | adopted.

  As described above, according to the high moisture content residue collecting apparatus of the present invention, the adhering matter adhering to the belt of the belt conveyor is removed by the cleaning means, and the removed residue is removed from the tail side horizontal portion of the collecting conveyor. Then, the carrier side belts of the main recovery conveyor and the secondary recovery conveyor carry the residue (attachment) while pinching it, and return it from the horizontal part on the head side of the secondary 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 needs to be collected, and even the residue is a fine raw material.

  And when the moisture content of the residue that is fed up while being held on the carrier side of the main recovery conveyor and the sub-recovery conveyor is high, the carrier side belt is strongly pressed by each pressurizing body rotating in the same direction to pinch the pressure Therefore, even if a residue having a high water content does not flow down between the two carrier belts, there is a specific effect that stable feeding can be performed while maintaining a very good clamping pressure.

  In particular, since the carrier side belt is bent in a continuous wave shape by pressing with the pressurizing body, there is an effect of suppressing the flow down.

  Moreover, it is provided in the interspersed position of an endless traveling body with a drive function provided on the back side (between the high place and the low place) of at least one return side belt of the main collection conveyor and the sub collection conveyor. Since the carrier side belt is pressed by the pressure member, the holding force of the residue can be greatly improved.

  For this reason, even a residue with a high water content is sandwiched well between the belts on both carrier sides, and there is a unique effect of maintaining stable feeding while suppressing the flow between the belts. As the pressure increases, the belt can be bent in a continuous wave to prevent the flow down.

Embodiments of the present invention will be described with reference to the accompanying drawings.
A shown in FIG. 1 of the first embodiment of the present invention is a belt conveyor.

  The belt conveyor A includes an endless belt 1 that is stretched between a head pulley and a tail pulley (not shown), a carrier roller 2 that supports the carrier-side back surface of the belt 1 in front and rear, and a belt 1. And a return roller 3 that supports the back side of the return side in parallel in the front-rear direction.

  Further, the adhering material (conveyed material) adhering to the surface of the return side belt 1 of the belt conveyor A is removed by the cleaning means B before the head pulley of the belt conveyor A.

  As the cleaning means B, in the case shown in the figure, a plurality of saddle members 4 arranged side by side on the circumference, and a spiral saddle 4 that is wound clockwise from the outer periphery center to one end and left-handed from the center to the other end. 5 is configured to transmit the rotation via a transmission mechanism (not shown) that spans the chain between the head pulley of the belt conveyor A and the pulley of the rotating body 6. The deposit may be removed by this method (with a rotating brush or the like).

  The removed collected deposit residue is returned (dispensed) onto the belt conveyor A by the main recovery conveyor C and the auxiliary recovery conveyor D.

  As shown in FIG. 1, the main recovery conveyor C crosses under the return side of the belt conveyor A so that the tail side horizontal portion receives the residue removed by the cleaning means B of the belt conveyor A. Next, it is composed of an upper feed portion extending upward and a head side horizontal portion extending from the upper feed portion to the side of the belt conveyor A. As shown in FIG. Located on the upper half of the tail side of the conveyor C, the carrier side overlaps with the carrier side upper feeding part of the main recovery conveyor C, and extends upward. The upper feeding part is connected to the carrier side of the belt conveyor A. The sandwiched residue (the residue is sandwiched and fed by the carrier side belts of the main collection conveyor C and the sub collection conveyor D) is discharged and is received on the belt conveyor A. Going on.

  Then, on the back side of the sandwiching carrier side belt where the main collection conveyor C and the sub collection conveyor D overlap, there is a circle that rotates and moves in the same direction while pressing the carrier side belt at the belt running direction interspersed position. The pressurizing bodies E are arranged in a circumferential arrangement.

  As shown in FIGS. 1, 2, 3, 4 and 5, the pressure body E is provided on the left and right frames 11 with a central support shaft 13 of a disc 12 supported on the support shaft 13 on one side. By driving the chain 15 over the sprocket 14 and driving the chain 15 (a single sprocket 14 is driven by a motor), each disk 12 is driven and pressed to the circumferentially equidistant positions of the pair of left and right disks 12. Although the center shaft 17 of the roller 16 as the body E is supported and provided, the present invention is not limited to this, and a pressurizing system with other configurations may be adopted.

  Then, the pressurizing bodies E of the main recovery conveyor C and the sub-recovery conveyor D are arranged so that when the two pressurizing bodies E contact the carrier side belt C ′ of the main recovery conveyor C, as shown in FIG. A single pressing body E is brought into contact with the carrier side belt D ′ of D to apply a clamping pressure due to good pressurization, but the carrier side belt C of the main recovery conveyor C as shown in FIG. The same action can be obtained by bringing a single pressurizing member E into contact with the carrier belt D ′ of the secondary recovery conveyor D.

  Further, as shown in the figure, the carrier side belts C ′ and D ′ are wave-shaped by arranging the upper and lower multi-stage parallel pressing bodies E of the main recovery conveyor C and the auxiliary recovery conveyor D in a staggered manner in the vertical direction. And the bending pressure by the carrier side belts C ′ and D ′ can be further improved.

  As shown in FIGS. 4 and 5, a U-shaped notch 18 facing inward from the periphery is provided at equal intervals on the periphery of the disc 12, and this notch 18 is opposed to the outer periphery of the end of the center shaft 17. By inserting the notch groove 19 provided at the position so as to be engaged by dropping, the center shaft 17 can be supported in a non-rotating state, the roller 16 rotates freely with respect to the center shaft 17, and the notch A stopper plate 20 is provided which is screwed so that the center shaft 17 does not escape from 18.

  In the figure, 21 is a tail pulley of the main collection conveyor C and the sub collection conveyor D, 22 is a head pulley of the main collection conveyor C and the sub collection conveyor D, and this belt is driven by driving the head pulley 22.

  If comprised as mentioned above, the deposit | attachment adhering to the return side of the belt conveyor A will be removed by the cleaning means B, and the removed residue will be received on the tail of the main collection conveyor C.

  The received residue is transported forward and is transported while being sandwiched between carrier side belts C ′ and D ′ where the main collection conveyor C and the sub collection conveyor D overlap.

  At this time, since the carrier side belt is pressed by the pressurizing body E, even if the moisture content of the sandwiched residue is high, the flow is suppressed as much as possible, and it is fed while maintaining good clamping, and the main recovery conveyor C It is possible to pay out to the belt conveyor A from the head.

  Next, a high moisture content recovery device of the second embodiment of the present invention will be described. The belt conveyor A, the cleaning device B, the main recovery conveyor C, and the auxiliary recovery conveyor D of the second embodiment. These are the same as in the first embodiment, and a detailed description thereof will be omitted. That is, the improvement is added to the configuration without the pressure body E rotating at the fixed position of the first embodiment.

  As shown in FIG. 8, at least one of the collection residues of the main collection conveyor C and the sub collection conveyor D is sandwiched between the carrier-side belts C ′ and D ′ on the back surface of the carrier-side belts C ′ and D ′. An endless parallel two-strip traveling body 31 with a drive function that travels from a high position to a high place is provided, and a sandwiching force is applied to the belts C ′ and D ′ on the sandwiching carrier side at the full length interspersed position of the traveling body 31. A pressurizing body F is provided.

  In the traveling body 31, a sprocket 32 with a drive function (by a motor) is arranged on one side of the upper and lower sides requiring the pressing and pressing body F, and an endless chain as the traveling body 31 is disposed on the upper and lower sprockets 32. 33, and the center shaft 35 of the roller 34 as the pressing and pressing body F is attached to the full length interspersed position of the left and right chains 33 through a mounting bracket (not shown) in a non-rotating state. The roller 34 rotates freely.

  And although the pressurization body F was provided only in the main collection conveyor C side in the illustration, it may be provided in both the sub collection conveyor D.

  At that time, when the pressing and pressing body F is provided only on the main recovery conveyor C, the return side belt D ′ of the auxiliary recovery conveyor D is prevented from being pushed away by the pressing force of the pressing and pressing body F. Is guided by a guide roller 36.

  If comprised as mentioned above, the deposit | attachment adhering to the return side of the belt conveyor A will be removed by the cleaning means B, and the removed residue will be received on the tail of the main collection conveyor C.

The received residue is transported forward and transported while being sandwiched between carrier side belts C ′ and D ′ where the main recovery conveyor C and the sub recovery conveyor D overlap.
At this time, since the carrier side belt is pressed by each roller 34 as the pressing and pressing body F of the traveling body 31, even if the moisture content of the sandwiched residue is high, the flow is suppressed as much as possible, and good clamping is maintained. However, it can be fed out and discharged from the head of the main recovery conveyor C to the belt conveyor A.
