  The present invention relates to a transfer device and a swinging opening / closing device, and in particular, a transfer casing provided with a loading mechanism at one end side, and a screw-type transfer mechanism that transports an object to be loaded supplied from the loading mechanism along the transport casing. The present invention relates to a transport device including a plurality of discharge mechanisms provided at the bottom of a transport casing along a transport direction of a transported object, and a swing opening / closing device used in such a transport device.

  After dehydrating sludge in sludge such as surplus sludge generated by biological treatment of wastewater, septic tank sludge, human waste treatment sludge, etc. to a water content of about 70% with a dehydration device such as a filter press device or a screw press device, it is used as an auxiliary agent. Processes such as incineration in municipal solid waste incinerators have been tried.

  A screw-type transport device is widely used as a transport device for transporting a granular material such as sludge or a wet substance. The sludge dewatered by the dehydrator is transported to a container by a screw-type transport device, and the entire container into which the sludge has been put is transported to the nearest refuse incineration facility.

  Also, the incineration ash from the incinerator, the molten slag from the melting furnace, the dry sludge from the dryer, and the like are temporarily stored in the container by the screw-type transfer device and transferred to the next step.

  When the sludge conveyed by such a conveyance device is dropped into the container from one discharge port provided on the downstream side of the conveyance device, the sludge is locally accumulated in the container, so that the container is accumulated in a mountain shape. In order to increase the amount to be charged into the inside, it is necessary to perform the leveling work manually, and there has been a problem that extremely complicated work is required.

  In Patent Document 1, a screw is rotatably housed in a screw casing provided with an inlet at an upper portion on one end side and a discharge port at a lower portion on the other end side, and is introduced into the screw casing from the inlet. There is disclosed a screw conveyor in which an object to be conveyed is conveyed by the screw and dropped and discharged from an outlet.

  As shown in FIG. 6, the screw conveyor is configured such that a screw 4 is housed in a screw casing 1 provided with an inlet 2 at an upper end on one end side, and is rotationally driven by an external drive device 12. A plurality of rectangular cylindrical outlets 3a, 3b, 3c, 3d are provided at required intervals in the transport direction at a lower portion on the other end side of the screw casing 1, and an opening amount is set for each of the outlets 3a, 3b, 3c, 3d. Adjustment gates 15 for adjustment are individually provided.

  Each of the adjusting gates 15 is formed in a flat plate shape corresponding to the size of the outlets 3a, 3b, 3c, and 3d, and is located at the upper end position of the downstream side wall of the outlets 3a, 3b, 3c, and 3d in the transport direction. Each of the outlets 3a, 3b, 3c, 3d is configured to be inserted into a corresponding one of the outlets 3a, 3b, 3c, 3d through a slit-shaped opening 16 formed so as to extend. It is configured to be slidable in the transport direction by being fitted to a guide member 17 that extends in the transport direction and is installed at a height position corresponding to the opening 16 on the inner surface of the wall. It should be noted that the reference numerals shown in FIG. 6 use the reference numerals given in Patent Document 1 as they are, and have no relation to the reference numerals in the drawings shown in the following embodiments.

  However, the above-mentioned adjusting gate is configured such that the opening amount is adjusted by sliding the flat gate member 15a corresponding to the size of the discharge ports 3a, 3b, 3c, 3d in the direction along the screw casing 1. Therefore, there is a problem in that the transported material is deposited and fixed between the rectangular tubular outlets 3a, 3b, 3c, 3d and the gate member 15a, and the sliding movement of the gate member 15a is hindered. .

  For example, by opening the gate member 15a in order from the discharge port 3d on the downstream side in the transport direction to the discharge port 3a on the upper stream side, if it is attempted to drop and load an object evenly into the container, the discharge port on the downstream side While the article is dropped from 3d, the article is deposited between the upstream rectangular outlets 3a, 3b, 3c and the gate member 15a, and is compacted and firmly fixed. There was a risk of doing so.

  In addition, when the gate member 15a is slid, the transported object deposited on the gate member 15a may enter the guide member 17 and hinder the subsequent smooth sliding movement of the gate member 15a.

  Further, when the gate member 15a is closed, there is a problem that the transported object is accumulated in the guide member 17.

  Returning to FIG. 1, the charging mechanism 10 is configured by a charging port 10A formed on the upper surface of one end side of the transport casing 2 in the upper cover 2A and a hopper 10B disposed above the charging port 10A. Although not shown, the sludge cut out from the silo in which the dewatered sludge is accumulated is transported to the upper part of the hopper 10B by a separate screw-type transport mechanism, and is dropped and supplied to the hopper 10B. .

  The screw blades 22 arranged around the rotation shaft 21 are formed in the opposite phase at the peripheral end of the transfer casing 2 so that the transferred object input from the inlet 10A is not clogged at the end of the transfer casing 2. , Are transported in the opposite direction.

  Below the three discharge mechanisms 30, containers 40 for receiving the dried sludge as the conveyed objects are arranged, and each conveyed object dropped from each discharge mechanism 30 is uniformly accumulated in the container 40. The interval between the discharge mechanisms 30 is set. On the upper cover 2A, an opening / closing lid 2B for inspection is installed above each discharge mechanism 30.

  The transport casing 2 is installed with an upward slope that is gradually inclined upward along the transport direction. In the present embodiment, the inclination angle θ is set to about 2.5 °. When the transported object is a wet material such as dehydrated sludge, it is possible to prevent the water oozing from the transported object from flowing down to the downstream side along the transport casing 2 when transported in the transport casing 2. To do

  The discharge mechanism 30C on the most downstream side is installed so as to be located immediately below an opposing portion between the screw blade 22 for forward conveyance and the screw blade 24 for reverse conveyance.

  The discharge mechanism 30 </ b> C includes a tubular body 301 extending downward from the transport casing 2 so as to cover a discharge port 10 </ b> C formed by cutting out the bottom of the transport casing 2, and transporting at a lower end side of the tubular body 301. An open / close plate 302 slidable along the casing 2 and a cylinder mechanism for driving the open / close plate 302 to move in and out are provided.

  The driving of the electric motor M is allowed on condition that the opening / closing plate 302 is driven to retreat so that the lower end of the cylindrical body 301 is opened. Is protected from clogging.

  Discharge mechanisms 30A and 30B having the same structure as the swing opening and closing device of the present invention are installed at the discharge port 10C on the most upstream side and the discharge port 10C adjacent to the downstream side. Hereinafter, the discharge mechanism 30A will be described in detail.

  As shown in FIGS. 2B and 2C and FIGS. 3A and 3C, the discharge mechanism 30A conveys the opening 11 of the discharge port 10C for dropping and discharging the transfer object to the bottom of the transfer casing 2. A lid 31 that is closed from the outside of the casing 2 and is in an open state in which the opening 11 of the outlet 10C is opened outward, and a swing mechanism that drives the lid 31 between the closed state and the open state. 50. The swing mechanism 50 is the drive mechanism of the present invention.

  The drive mechanism for opening and closing the lid 31 is not only constituted by the swing mechanism 50 but also includes a moving mechanism for moving the lid 31 downward so as to be separated from the outer surface of the transport casing 2. It may be configured to swing and drive after the downward movement.

  The discharge port 10C has a U-shaped cross section as viewed in the transport direction, and has a rectangular shape as viewed from the side. Further, the lid 31 is formed in a gutter shape so as to close the discharge port 10C from the outside, and four ribs 31A are formed for securing strength (see FIGS. 2B and 2C).

  The swing mechanism 50 is disposed on the downstream side in the transport direction with respect to the discharge port 10 </ b> C, and supports the swing shaft 51 so that the swing shaft 51 is in a posture orthogonal to the axis of the transport casing 2 in plan view. 1 bracket 53, a piston cylinder mechanism 60 that swings the lid 31 around the swing axis 51, and a piston cylinder mechanism 60 that is arranged downstream of the discharge port 10 </ b> C in the conveyance direction and swings the piston cylinder mechanism 60 around the swing axis 58. And a second bracket 56 movably supported (see FIGS. 2B and 2C).

  The first bracket 53 and the second bracket 56 are formed to extend from a support portion 55 welded to the outer periphery of the transport casing 2 on the downstream side of the discharge port 10C. In addition, a pair of support plates 33 are formed to extend downward on the downstream side in the transport direction of the lid 31, and swing so as to penetrate through openings formed in the pair of support plates 33 and the pair of first brackets 53, respectively. The driving shaft 51 is bridged (see FIGS. 2B and 2C).

  A pair of support plates 57 extend below the second bracket 56, and a piston cylinder mechanism 60 is swingably supported around a swing shaft 58. A tip of a piston shaft 61 provided in the piston cylinder mechanism 60 is a cover. The body 31 is swingably attached via a swing shaft 62 to a mounting portion 32 extending and formed at the lower center of the body 31. In the present embodiment, the piston cylinder mechanism 60 is constituted by an air cylinder driven by compressed air, but may be constituted by a hydraulic cylinder mechanism or an electric power cylinder mechanism (see FIGS. 2B and 2C). ).

  As described above, the swing shaft 51 is supported by the first bracket 53 disposed downstream of the discharge port 10C in the transport direction, and the second bracket 56 similarly disposed downstream of the discharge port 10C in the transport direction. The lid 31 is swingably driven around the swing shaft 51 between an open state and a closed state by a piston cylinder mechanism 60 which is swingably supported via a swing shaft 58.

  Since the piston cylinder mechanism 60 is swingably supported by the second bracket 56 via the swing shaft 58, the point of action P 1 of the lid 31 by the piston cylinder mechanism 60 is concentric with the swing shaft 51 of the lid 31. The lid 31 can be urged to swing so as to be positioned above (see FIGS. 3A and 3C).

  Further, the swing shaft 51 is formed on the first bracket 53 and supported movably along a long hole 54 inclined obliquely upward toward the transport casing 2, and the piston cylinder mechanism 60 swings the lid 31 to an open state. When oscillating, the oscillating shaft 51 moves downward along the elongated hole 54, and when the lid 31 is oscillated to be closed by the piston cylinder mechanism 60, the oscillating shaft 51 is moved to the elongated hole 54. It is configured to move upward along (see FIGS. 3A to 3D).

  When the lid 31 swings around the swing shaft 51, the swing shaft 51 moves below the elongated hole 54 formed in the first bracket 53, so that the dimensional accuracy of the swing mechanism and the cover may vary. Even if there is, the opening and closing swing can be performed smoothly without generating a twist between the lid 31 and the transport casing 2 (see FIGS. 3C and 3D).

  When the piston cylinder mechanism 60 is driven to swing the cover 31 from the open state to the closed state, the cover 31 is swung while the swing shaft 51 is positioned below the elongated hole 54. Finally, the lid 31 can be brought into close contact with the transport casing 2 with high accuracy by pressing and moving the swing shaft 51 upward along the long hole 54 (see FIGS. 3A and 3B).

  An elastic member that is a spring that biases the swing shaft 54 so that the swing shaft 51 moves upward along the elongated hole 54 when the lid 31 is swing-driven to the closed state by the piston cylinder mechanism 60. 70 extends between the swing shaft 51 and the second bracket 56.

  The rocking shaft 51 is pressed by the elastic member 70 so that the rocking shaft 51 rocks in a state where the rocking shaft 51 is located above the elongated hole 54 at the initial stage when the lid 31 rocks from the closed state to the open state. Swings from an open state to a closed state at an initial stage, the swinging shaft 51 swings in a state positioned below the elongated hole 54, and when approaching the closed state, the swinging shaft 51 is pressed by the elastic member 70. The lid 31 comes into close contact with the transport casing 2.

  In addition, when the feed casing 2 is installed with an upslope that is gradually inclined upward along the transport direction, it is preferable that the elastic member 70 is mounted, but it is not essential.

  A discharge port 10C for dropping an object to be transferred is formed at the bottom of the transfer casing 2, and the lid 31 swings between a closed state in which the discharge port 10C is closed by the swing mechanism 50 and an open state in which the discharge port 10C is opened. Since the driven object is driven, the transferred object is easily dropped when the cover 31 is swingably driven to the open state even if the transferred object conveyed inside the transfer casing 2 accumulates on the lid 31 in the closed state. Therefore, the transported object does not adhere to the lid 31, and even if the transported object adheres to the lid 31, there is no problem in opening and closing the lid by the swing mechanism 50.

  It is preferable that a convex portion (not shown) is formed on the inner surface of the lid 31 so that the inner surface of the lid 31 and the inner surface of the transport casing 2 are flush with each other in the closed state. With this configuration, the transported object transported inside the transport casing 2 does not accumulate on the lid 31 in the closed state.

  That is, if a convex portion having a thickness equal to the thickness of the transport casing 2 is formed, the cover 31 closes the discharge port 10 </ b> C so as to close the transport casing 2 from the outside. Thus, a transport surface is formed in which the front surface and the convex portion of the lid 31 are smoothly continuous.

  The above-described transport casing 2, the transport mechanism 20, the lid 31, and the like can be made of a metal material such as SS or SUS.

  As shown by a dashed arrow in FIG. 4, when the lid 31 shifts from the closed state to the open state, the lid 31 jumps out in the transport direction due to the inertial force acting on the transported object transported in the transport casing 2 by the transport mechanism 20. Even in this case, the transported object is received by the inner surface of the lid 31 that is swingably driven around a swing axis disposed on the downstream side in the transport direction with respect to the discharge port 10C, and is transported along the inner surface of the lid 31. Since the object falls directly below, the conveyed object falling from the discharge port 31 does not scatter into the container 40 and stably falls directly below.

  Similarly, even if the conveyed object fixed to the screw blade 22 and conveyed to the downstream side falls to the discharge port 10C on the way, the conveyed object is received by the inner surface of the lid body 31 and along the inner surface of the lid body 31. Since the transported object falls directly below, the transported object falling from the discharge port 31 similarly falls down stably without scattering into the container 40.

  In other words, since the swing shaft 51 is disposed downstream of the discharge port 10C in the transport direction, the lid 31 receives the transported object falling from the discharge port 10C in the open state and guides the fall to a predetermined position. Function as a part.

  The maximum swing angle φ of the lid 31 is preferably set to an angle larger than the angle of repose of the conveyed object, and the conveyed object dropped from the discharge port 10C is downwardly deposited without accumulating on the inner surface of the lid 31. You will fall.

The above-described transport device 1 is configured to be automatically controlled by a control device incorporating a microcomputer or the like.
As shown in FIG. 5, the control device includes a level sensor LS such as an optical sensor that is installed above each side of the discharge mechanisms 30A, 30B, and 30C and that detects the height of a conveyed object that has fallen into the container. Output is input.

  When transporting the dried sludge to be transported to the container 40, the control device closes the discharge mechanisms 30A and 30B on the upstream side and shifts the discharge mechanism 30C on the most downstream side to the open state, and then shifts the electric motor M to the open state. Is activated to allow conveyance (see FIG. 1).

  When the level sensor LS detects that the height of the conveyed object that has fallen into the area corresponding to the discharge mechanism 30C in the container 40 has reached a predetermined height, the central discharge mechanism 30B is controlled to the open state. As a result, the transported object is dropped into an area of the container 40 corresponding to the discharge mechanism 30B.

  Similarly, when the level sensor LS detects that the height of the transported object that has dropped into the area corresponding to the discharge mechanism 30B of the container 40 has reached a predetermined height, the discharge mechanism 30A on the most upstream side. Is controlled to be in the open state, thereby causing the transported object to drop into an area of the container 40 corresponding to the discharge mechanism 30A.

  When it is detected by the same level sensor LS that the height of the transported object that has dropped into the area corresponding to the discharge mechanism 30A of the container 40 has reached a predetermined height, the transport mechanism is stopped after a certain time has elapsed.

It becomes possible to cope with a configuration in which a plurality of containers 40 are installed along the transport casing 2. The number of discharge mechanisms is not limited, and may be set as appropriate according to the size of the container. Further, the most downstream discharge mechanism 30C may have the same configuration as the upstream discharge mechanisms 30A and 30B.

  As described above, the swing opening and closing device of the present invention can be used to open and close the lid of another device other than the transport device, and has a lid that opens and closes a discharge port formed at the bottom of the casing, A swing opening / closing device comprising a swing mechanism for swinging and driving the lid around a swing axis between a closed state in which the outlet is closed and an open state in which the discharge port is opened, and is configured as follows. Just do it.

  That is, the swing mechanism includes a first bracket that supports the swing axis such that the swing axis is orthogonal to the axis of the casing in plan view, and a piston cylinder that swings and drives the lid around the swing axis. Mechanism, and a second bracket for swingably supporting the piston cylinder mechanism, wherein the swing shaft is formed on the first bracket and is movably supported along a long hole inclined obliquely upward toward the casing. When the lid is driven to swing open by the piston cylinder mechanism, the swing shaft moves downward along the elongated hole, and when the lid is driven to swing closed by the piston cylinder mechanism, the swing shaft moves. What is necessary is just to be comprised so that a driving shaft may move upward along a long hole.

  Also, an elastic member is provided for urging the swing shaft so that the swing shaft moves upward along the elongated hole when the lid is swingably driven by the piston cylinder mechanism in the closed state. Is preferred.

  As described above, the embodiments of the present invention have been described, but the present invention is not limited by the description, and the specific shapes, sizes, materials, and the like of the respective parts are appropriately changed within a range in which the effects of the present invention are exerted. Needless to say, it can be designed.
