Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure vessel with an opening / closing lid which is used with an internal pressure lower than or higher than atmospheric pressure, and in particular, a pressure reducing type for promoting drying by lowering the internal pressure below atmospheric pressure. It is suitable for a container of a drying device.

[0002]

2. Description of the Related Art Most conventional pressure vessels having an opening / closing lid are used in factories, that is, they are used only by workers who have mastered the technique of using pressure vessels. Therefore, there is almost no trouble such as careless opening and closing of the open / close lid or accidental insertion of a foreign substance, and no lock mechanism is provided on the open / close lid.

Further, it is indispensable to provide a sealing material between the opening / closing lid and the container body to maintain airtightness. Since the conventional pressure container is operated and maintained by an engineer, maintenance is performed. If the material was damaged, it was possible to take immediate action.

[0004]

However, in recent years, not only specialists but also ordinary people are operating the pressure vessel. For example, the applicant of the present application has proposed a drying apparatus which is mainly used in restaurants and the like, and which dries water-containing substances such as raw garbage (JP-A-8-3577).
No. 5), in this water-containing material drying treatment apparatus, the pressure in the pressure vessel for drying the water-containing material is set lower than atmospheric pressure to accelerate the drying. The opening / closing lid of such a pressure vessel is
It should not be opened during the drying operation, and should not be inadvertently opened to introduce foreign matter even when it is not in operation.

In order to prevent such inconvenience, it is conceivable to provide a locking mechanism on the opening / closing lid. However, if the locking mechanism is simply provided, the handle can be repeatedly operated in the opening direction or forced with a strong force. When operated, the force at this time is transmitted to the lock, causing a problem of damaging the lock or the lever in the middle.

Further, in the hinge mechanism for supporting the opening / closing lid so that it can be opened / closed, since the opening / closing lid rotates about the axis connecting the opening / closing lid and the container body, when the opening / closing lid is closed, the sealing material is on the hinge mechanism side. The part is sequentially pressed against the container body side. For this reason, the sealing material is crushed more strongly than necessary on the hinge mechanism side, and the elasticity tends to be lost. In particular, when used by an ordinary person, it is difficult to notice the damage of the sealing material, and the inspection tends to be neglected, which may result in a problem in durability.

Therefore, according to the present invention, it is possible to prevent the opening / closing lid from being opened / closed carelessly or foreign matter to be introduced, and the durability of the sealing material between the opening / closing lid and the container body is improved. It is an object of the present invention to provide a pressure vessel that can prevent inconvenience caused by having an opening / closing lid, such as being able to increase the pressure.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a water-containing material drying treatment apparatus 1 equipped with a pressure vessel, and FIG. 2 is a diagram for explaining the outline of its internal structure.

The water-containing substance drying treatment apparatus 1 includes a pressure vessel 4 functioning as a drying tank, a decompression mechanism for lowering the internal pressure of the pressure vessel 4, and the like in a housing 3 in which an operation panel 2 is erected on the rear side. The pressure reducing mechanism is provided to reduce the pressure inside the pressure vessel 4, thereby lowering the boiling point of the water-containing material (water contained in the material to be dried) and promoting the drying.

The pressure reducing mechanism will be briefly described with reference to FIG.
As shown in FIG. 3, an ejector 6 functioning as a vacuum generator is provided on the discharge side of the pump 5, the outlet side of the ejector 6 is connected to the inlet side of the storage tank 7, and the radiator 8 is attached to the lower end outlet side of the storage tank 7. A water circulation system 9 and a suction port that opens in the middle of the nozzle of the ejector 6 having a reduced flow passage cross-sectional area and the pressure vessel 4 are connected by a suction pipe 10. The negative pressure generated by the ejector 6 reduces the pressure inside the pressure container 4.
A drainage port 11 is provided in the storage tank 7.

The pressure vessel 4 is provided between a container body 12 having an opening on the upper surface, an opening / closing lid 13 capable of opening and closing the opening, and one side of the opening / closing lid 13 and the container body 12 side. A hinge mechanism 14 that rotatably supports the lid 13, a locking mechanism 15 that locks the opening / closing lid 13 in a closed state, and at least one of the opening / closing lid 13 and the container body 12 that face each other,
It has a sealing material 16 that abuts and seals between the opening / closing lid 13 and the container body 12. A heater 17 as a heating means is attached to the outer surface of the bottom surface of the container body 12, and a rotary blade 19 that is rotated by the drive of a motor 18 with a speed reducer is provided inside the rotary blade 1.
The fixed blade 20 is provided horizontally on the inner peripheral surface above 9 so as to be centered. An atmosphere release valve 21 is provided on the outer peripheral surface of the container body 12 immediately below the upper opening, and an outlet 22 is provided on the outer peripheral surface near the bottom.

In the water-containing substance drying treatment apparatus 1 having the above-mentioned structure, the opening / closing lid 13 is opened and the container main body 1 is opened from the upper opening.
A water-containing material such as garbage is put into the inside of 2, and the opening / closing lid 13 is closed, and then the atmosphere opening valve 21 is closed. When the pump 5 is operated in this state, the inside of the pressure vessel 4 is gradually depressurized by the negative pressure action of the ejector 6. And the heater 17
When the water-containing material is heated by the rotation of the rotary blades 19 while being stirred by the heat of the water, the water content evaporates, and the water vapor evaporates.
After passing through 0, they are merged into the circulation flow by the ejector 6, and when they are merged, they are cooled and liquefied. Then, when the water vapor evaporated from the water-containing substance joins the circulation flow and the amount of circulating liquid increases, it overflows and is discharged to the outside from the drainage port 11. Since the deodorizing filter 23 is provided inside the storage tank 7 and is repeatedly circulated through the deodorizing filter 23 to deodorize, the liquid discharged from the drainage port 11 has almost no bad odor.

The water-containing material heated in the depressurized state in this way gradually loses water while being subjected to the stirring and pulverizing action of the rotary blade 19 and the fixed blade 20, so that even if it is muddy at the beginning of the drying process, When fully dried, it eventually becomes a powder. When the drying process is completed, the atmosphere release valve 2
1 is opened and the inside of the pressure vessel 4 is returned to atmospheric pressure.
Rotating the rotary blades 19 with 2 open,
The powdery material to be dried is taken out from 2.

Next, the hinge mechanism 14 will be described.
In the pressure vessel 4 according to the present embodiment, since the upper opening of the bottomed cylindrical vessel body 12 is opened and closed by the circular opening / closing lid 13, the hinge mechanism 14 is provided at two locations inside the opening / closing lid 13 (on the operation panel 2 side). The hinge mechanism 14 supports the open / close lid 13 so as to be openable and closable. Both hinge mechanism 14
Are symmetrical with respect to the left and right, but since the structures are the same, only one shown in FIGS. 4 and 5 will be described.

The hinge mechanism 14 is provided with a bearing 25 fixed to the top plate 3'of the housing 3 on the container body 12 side by bolts 24, and a horizontal sub-direction along the operation panel 2 on the bearing 25. Long swing member 2 attached to the front and rear through a shaft 26 so as to swing in accordance with the turning direction of the opening / closing lid 13.
7 and a hinge for urging one end portion (a front end portion, which is the left side in FIGS. 4 and 5 in the present embodiment) of the swinging member 27 swinging around the auxiliary shaft 26 downward on the container body 12 side. Coil spring 30 as a biasing member, and swing member 27
The main arm is a cover arm 32 as a shaft-attaching member that is attached to the other end portion (rear end portion) of the main shaft 31 that is arranged in parallel with the sub shaft 26 and that is integrally provided on the opening / closing cover 13. is there.

In order to mount the coil spring 30 on the swing member 27, a storage hole 33 having a large diameter at the upper side and a small diameter at the lower end portion is vertically formed in the swing member 27, and the large diameter of the storage hole 33 is provided. The coil spring 30 is housed in the diametrical portion, the bolt 34 is inserted so as to penetrate the coil spring 30 from above, and the male screw portion at the lower end of the bolt is tightened to the top plate 3 ′ side. The coil spring 30 is attached so that the upper end of the coil spring 30 is held down by the head.

Therefore, by adjusting the tightening amount of the bolt 34, the urging force by which the coil spring 30 urges the front end side of the oscillating member 27 downward can be appropriately adjusted. That is, it is an urging force that swings the swinging member 27 in the sinking direction in which the main shaft 31 approaches the container body 12 side due to the movement of the center of gravity of the opening / closing lid 13 when the opening / closing lid 13 is closed. By moving the center of gravity of the opening / closing lid 13, the main shaft 31 can be set to the urging force that urges the swinging member 27 in the floating direction separating from the container body 12.

Further, the rocking member 27 is provided with a stopper for restricting the rocking range, and when the opening / closing lid 13 closes the opening of the container body 12, the rocking member 27 restricts the rocking range by the stopper. The sealing member 16 is configured to abut substantially in parallel by the closing operation of the opening / closing lid 13 after the restriction. Specifically, a horizontal position adjusting bolt 35 is screwed from below onto the lower surface of the swinging member 27 in a portion in front of the counter shaft 26 so that the downward protrusion length can be adjusted.
A maximum subsidence position adjusting bolt 36 is screwed into a portion rearward of 6 in a state where the downward protrusion length can be adjusted from below.

The opening / closing lid 13 supported by the hinge mechanism 14 having the above-mentioned structure is at the free end side (the hinge mechanism 14).
When the open handle 37 provided on the opposite side) is lifted by hand to rotate about the main shaft 31, the center of gravity moves to the hinge mechanism 14 side by this rotation, and the rear end portion of the swing member 27. Since the downward load exerted on the main shaft 31 by the main shaft 31 increases, the swinging member 27, which was biased horizontally by the biasing force of the coil spring 30, loses the load and swings around the sub shaft 26.

Therefore, when the opening / closing lid 13 is opened to some extent, the swinging member 27 swings about the auxiliary shaft 26 in the direction of sinking the rear end portion against the biasing force, whereby the main shaft 3 is rotated.
1 descends and the lower end of the maximum sunken position adjusting bolt 36 comes into contact with the top plate 3 ', the descent of the main shaft 31 stops at this point. Even if the lowering of the spindle 31 is stopped, the spindle 31
The opening / closing lid 13 can be opened up to a necessary and sufficient angle with respect to.

Next, the case of closing the opening / closing lid 13 will be described. When the opening / closing lid 13 is rotated about the main shaft 31 by holding the handle 37 or the like and pushing it down, the center of gravity moves in the direction away from the hinge mechanism 14 by this return rotation operation, and the swinging member 27. Since the load applied to the rear end portion is reduced, when the opening / closing lid 13 is pushed down to some extent, the biasing force of the coil spring 30 overcomes the load of the main shaft 31. Therefore, when the opening / closing lid 13 is closed to some extent, the swinging member 27 swings back and swings in the direction of raising the rear end portion by the biasing force of the coil spring 30 about the counter shaft 26, and when swinging back sufficiently,
The lower end of the horizontal position adjusting bolt 35 comes into contact with the top plate 3 ', and the swinging member 27 stops in a substantially horizontal posture. Therefore, with the return swing of the swing member 27, in other words, when the opening / closing lid 13 is closed to some extent, the main shaft 31 floats. When the swing member 27 swings back and the main shaft 31 rises, the center of rotation of the opening / closing lid 13 rises, so that the space between the lower surface of the opening / closing lid 13 and the upper opening edge of the container body 12 is increased. The angle decreases as the spindle 31 moves up.

Therefore, when the opening / closing lid 13 is closed, the sealing material 16 provided on the lower surface of the opening / closing lid 13 has the hinge mechanism 1.
The time when the portion on the fourth side contacts the container body 12 is delayed due to the rise of the main shaft 31. Therefore, when the opening / closing lid 13 is closed, the sealing material 16 starts to contact the container body 12 at an angle that is substantially horizontal, and the handle 3
Opening / closing lid 13 until the locking mechanism 15 provided on the 7 side can be locked
Even if is fully closed, it is possible to prevent a part of the hinge mechanism 14 side from being crushed more than necessary.
In particular, the seal material 16 having a lip tends to lose elasticity or be damaged by the lip when a part is compressed excessively more than necessary. However, when it is compressed almost uniformly as in the present embodiment, The airtightness can be secured without applying a strong compressive force, and the durability of the lip is improved in combination with the substantially uniform pressure contact.

In this embodiment, in order to save space, the coil spring 30 is provided at the front end of the swinging member 27 with the auxiliary shaft 26 interposed therebetween, and the main shaft 31 is provided at the rear end thereof.
However, the mounting positions of the coil spring 30 and the main shaft 31 may be reversed.

When the opening / closing lid 13 is fully closed by the above-mentioned operation, the locking mechanism 15 can lock the lid. The locking mechanism 15 is attached to the container body 12 side and is engaged with an engagement member 40 described later, and an engagement receiving member 41 is rotatably attached to the opening / closing lid 13 side to close the opening / closing lid 13. In the state, the engaging member 40 that engages with the engagement receiving member 41 to maintain the closed state, the spring 42 as the urging member that urges the engaging member 40 to the closed state side, and the opening / closing lid 13 side. In the vicinity of the opening operation input member 43, which is rotatably attached and used by an operator to perform an opening operation, an opening operation input member 43 that moves in association with the opening handle 37, and an engagement member 40 that operates in association with An opening operation is performed by engaging both the opening operation force receiving member 44 that moves and the opening operation input member 43 and the opening operation force receiving member 44 and moving as the opening operation input member 43 moves in the opening direction. The first state in which the force is transmitted to the opening operation force receiving member 44 and the opening operation input The opening operation force deviates from at least one member 43 or an opening operation force receiving member 44 the opening operation force receiving member 4
4 is provided on the side of the opening / closing lid 13 and an opening operation force transmission member 45 that can be converted into a second state in which the transmission force is not transmitted to the No. By operating the lock 47 and the key 49 inserted in the lock 47 to one side, the opening operation force transmitting member 45 is converted into the first state against the urging force of the transmitting member urging member 46. A state regulation that allows the opening operation force transmission member 45 to be restored to the second state by the urging force of the transmission member urging member 46 by operating the key 49 to the other while maintaining the first state. It is composed of a member 50 and the like.

The engaging member 40, as shown in FIGS.
It has an inverted L-shape having a pair of left and right vertically long plate pieces having engaging claws 51 protruding rearward at the lower end, and arm pieces extending rearward from the upper ends of the plate pieces, and the middle of the arm piece is a spindle. It is rotatably (swingably) pivotally attached to the base 53 by 52. The base 53 is attached to the lower surface of the opening / closing lid 13 via a bracket 54. A downward cross-section consisting of an upper surface portion, a front wall portion extending downward from the front end of the upper surface portion, and a rear wall portion extending downward from the rear end so as to connect both rear ends of the arm piece. A U-shaped opening operation force receiving member 44 is integrally provided, and horizontally long slits 55 are formed in front and rear walls of the opening operation force receiving member 44.
It is opened to penetrate. Therefore, the opening operation force receiving member 44 shares the arm piece with the engaging member 40, and the supporting shaft 5
It is possible to move up and down in an arc shape in conjunction with the engaging member 40 that rotates around the center 2.

The open handle 37 has a horizontally long handle portion provided inside the engaging member 40 and an arm portion extending rearward from each of the left and right ends of the handle portion. It is pivotally attached to a base 53 by a penetrating support shaft 52 so as to be rotatable (swingable). Further, an opening operation input member having a hook-shaped cross section, which is composed of an upper surface portion and a front wall portion extending downward from a front end of the upper surface portion so as to connect a rear end of an arm portion extending rearward from the handle portion. 43 is provided. Then, the opening operation input member 43
The lengths of both arm portions are set so as to be positioned immediately in front of the opening operation force receiving member 44 described above.

The opening operation force transmitting member 45 is a plate member having a plate-shaped transmitting portion extending in the horizontal direction and a contact portion 60 formed by bending the rear end of the transmitting portion upward. Part 60
Is formed into a curved surface shape (a surface having a curvature larger than the circular arc surface centering on the support shaft 52) that does not approach the state regulating member 50 side described later even if the opening operation force transmitting member 45 moves in the circular arc shape. is there. The opening operation force transmitting member 45 is mounted on the upper surface of the opening operation force receiving member 44 by the shaft 61 on one side of the transmitting portion with the transmitting portion inserted from the rear into the slit 55 of the opening operation force receiving member 44. The other end of a coil spring as a transmission member urging member 46, which is rotatably attached to the shaft and has one end connected to one side of the contact portion 60, is connected to the base 53, and is transmitted by the urging force of the coil spring 46. The portion is retracted so that the transmission portion does not largely protrude from the front slit 55 of the opening operation force receiving member 44, that is, is biased to the second state in which the opening operation force is not transmitted.

The lock 47 shown in the drawing is a cylinder lock, and a standing wall 62 is provided upright at the rear end of the base 53.
It is attached by inserting it from above into a hole formed in the lock attaching portion 63 extending rearward from the upper end of the above and screwing a nut 64 into the hole. Then, when the cam piece-shaped state regulating member 50 is attached to the shaft 65 protruding from the lower end of the cylinder lock 47 and the key 49 inserted into the key 49 hole of the cylinder lock 47 is operated to rotate, the state regulating member 50 moves to the standing wall 62. Through window 6
It is configured to move forward and backward from 6.

In the locking mechanism 15 having the above-mentioned structure, when the opening / closing lid 13 is pushed down to close the opening of the container body 12, the oblique side of the engaging claw 51 of the engaging member 40 engages with the engaging receiving member 41.
When the open / close lid 13 is pushed down, the engaging member 4
0 rotates against the urging force of the spring 42, and when the opening / closing lid 13 is further pushed down so that the projecting end of the engaging claw 51 passes through the engaging receiving member 41, the engaging member 40 urges the spring 42. Thus, the engaging claw 51 is engaged with the engagement receiving member 41 by rotating back, and the open / close lid 13 is held in a closed state.

In this engaged state, when the inserted key 49 is operated to retract the tip end portion of the state regulating member 50, the opening operation force transmitting member 45 is retracted by the urging force of the coil spring 46, and this retracted opening is performed. The tip transmission portion of the operation force transmission member 45 does not reach within the vertical movement range of the opening operation input member 43. That is, when the key 49 is operated, the opening operation force transmitting member 45 converts the opening operation force due to the movement of the opening operation input member 43 into the second state in which it is not transmitted to the opening operation force receiving member 44. Therefore, if the key 49 is pulled out while the opening operation force transmission member 45 is in the second state while the opening / closing lid 13 is closed and the drying process is performed or after all the operations are stopped, the opening handle 37 is accidentally opened. Even if the opening operation input member 43 is moved up and down by operating in the opening direction, the opening operation force transmitting member 45 does not engage and move up and down together. Therefore, the opening operation force at this time is the opening operation force receiving member. Not transmitted to 44. Therefore, even if the opening operation is performed by raising the opening handle 37 and lowering the opening operation input member 43, the opening / closing lid 13 maintains the closed state.

Therefore, there is no possibility that foreign matter will be put into the pressure vessel 4 during the operation stop, and the opening / closing lid 13 will not be forcibly opened during the drying process. Also, open handle 37
Even if an attempt is made to forcefully release the force, the force from the opening handle 37 is transmitted to the lock-constituting member such as the state regulating member 50 because the edge of the transmission system is cut off after the opening operation input member 43. Never be done. Therefore, it is possible to prevent damage to the state regulation member 50 and the like due to the force applied to the open handle 37 by force.

On the other hand, when the opening / closing lid 13 is opened, such as when the next drying target is put in after the drying process is completed, the key 49 inserted in the lock 47 is operated to move the tip of the state regulating member 50 forward. The opening operation force transmitting member 45 is pressed to move forward against the biasing force of the coil spring 46, and the forward end transmitting portion of the advanced opening operation force transmitting member 45 reaches the vertical movement range of the opening operation input member 43. To do. That is, when the key 49 is operated, the opening operation force transmitting member 45 is engaged with the opening operation input member 43 and is converted into the first state in which the opening operation force is transmitted to the opening operation force receiving member 44.

In this first state, when the opening handle 37 is opened and the opening operation input member 43 is lowered, the opening operation force transmitting member 4 is opened.
5 is pressed by the opening operation input member 43 and descends, and by this descending, the opening operation force receiving member 44 rotates in the descending direction.
Therefore, the engaging member 4 that interlocks with the opening operation force receiving member 44
0 rotates in the opening direction, and the engagement claw 51 at the lower end is engaged with the engagement receiving member 4
Depart from 1. In this manner, when the hook-shaped engaging member 40 on the opening / closing lid 13 side is disengaged from the engagement receiving member 41 on the container body 12 side, the open end of the opening / closing lid 13 is released since the free end is already unconstrained. Opening and closing lid 1
3 can be opened.

Even when an excessively strong force is applied when opening the opening handle 37, the opening operation force transmitting member 45 is supported by the opening edges of the front and rear slits 55, and particularly the front slit 55 is opened. Since it is located near the input member 43, it does not receive a large bending force when transmitting the opening operation force. Therefore, even if the opening operation force is repeatedly applied for a long period of time, the plate-like opening operation force transmitting member 45 is not damaged such as being bent.

Further, in the first state, the opening operation force transmitting member 45 connects the opening operation input member 43 and the opening operation force receiving member 44 and rotates integrally with the support shaft 52 as a center. Therefore, the front end of the state regulating member 50 that is in contact with the rear end contact portion 60 is in sliding contact. In the present embodiment, the contact portion 60 is formed into a curved surface shape that does not approach the state regulating member 50 side even if the opening operation force transmission member 45 moves in an arc shape.
Therefore, even if the opening operation force transmitting member 45 moves up and down in an arc by the opening operation, the curved portion of the contact portion 60 does not push the state regulating member 50 backward.
Therefore, a strong frictional resistance force does not act on the contact portion 60, and a strong bending force does not act on the state regulating member 50. Therefore, even if the opening operation force transmitting member 45 moves up and down for a long period of time, it is possible to prevent the opening operation force transmitting member 45 and the state regulation member 50 from being damaged, and improve the durability. it can.

In the above embodiment, the engaging member 40 is used.
Although it is formed integrally with the opening operation force receiving member 44, both members may be molded separately and connected via a transmission mechanism such as a link mechanism.
