The tube end 31a of the one end portion 31 is formed as a joint that can be connected to an external hose (not shown). A first opening / closing damper 34 as a first opening / closing body is provided at the other end 32 of the introduction pipe 3. The first opening / closing damper 34 is provided outside the tube end 32 a of the other end 32 by a hinge 35 so as to be openable and closable.
a is closed from the outside, and the tube end 32a is opened by rotating outward from the tube end 32a. That is, the first opening / closing damper 34 allows only the introduction of the stored matter into the tank body 1 through the introduction pipe 3, and prevents the discharge of the stored matter through the introduction pipe 3. On the other hand, the discharge pipe 4 is arranged horizontally along the bottom surface of one end of the tank body 1 and has one end 4
1 is connected to an intermediate portion on the one end 31 side of the introduction pipe 3. That is, the discharge pipe 4 and the introduction pipe 3 are integrated by forming the discharge pipe 4 into a shape branched off from the middle of the introduction pipe 3. The other end 42 of the discharge pipe 4 is provided with a second opening / closing damper 43 as a second opening / closing body. The second opening / closing damper 43 is provided to be openable and closable by a hinge 44 inside the tube end 42 a of the other end 42.
a is closed from the inside, and the tube end 42a is opened by rotating inward from the tube end 42a. That is, the second opening / closing damper 43 permits only the discharge of the stored material from the inside of the tank main body 1 through the discharge pipe 4, and prevents the introduction of the stored material through the discharge pipe 4. Next, a description will be given of a case where the stored material is introduced and stored in the storage tank configured as described above, and a case where the stored material is discharged. First, the case where the stored material is introduced into the tank body 1 and stored will be described. An external hose is connected to the pipe end 31a of the introduction pipe 3, and after opening and closing the on-off valve 33, the stored material is introduced into the tank body 1 through the external hose by suction or pushing. As a result, the stored matter is guided from the one end 31 to the other end 32 through the middle part in the introduction pipe 3 and the first opening / closing damper 34 is forcibly turned outward to be opened by this rotation. It is introduced into the tank main body 1 through the pipe end 32a of the other end portion 32 and stored. At this time, even if the stored matter is introduced from the introduction pipe 3 to the discharge pipe 4 side, the second opening / closing damper 43 provided on the discharge pipe 4 permits only the discharge of the stored matter, 4
Therefore, the stored matter is not introduced into the tank body 1 through the discharge pipe 4. Therefore, the stored material is introduced into the tank main body 1 only through the introduction pipe 3 through the first opening / closing damper 34, and after storing a predetermined amount of the stored material, the opening / closing valve 33 is closed. Is stored in Next, the case where the stored material stored in the tank body 1 is discharged as described above will be described. After an external hose is connected to the pipe end 31a of the introduction pipe 3 as necessary, the on-off valve 33 is opened, and the stored matter can be discharged through the external hose by natural discharge or suction to the outside. Specifically, by opening the on-off valve 33, the stored matter forcibly rotates the second on-off damper 43 inward due to its own weight or suction action, and the discharge pipe 4 opened by this rotation. Is introduced into the discharge pipe 4 through the pipe end 42 a of the other end 42 of the discharge pipe 4, and is discharged from one end 41 of the discharge pipe 4 to the outside through the one end 31 of the introduction pipe 3 or an external hose. At this time, the first opening / closing damper 34 provided at the other end of the introduction pipe 3 permits only the introduction of the stored material, and prevents the discharge of the stored material through the introduction pipe 3. Therefore, the stored matter is not discharged outside through the introduction pipe 3. By providing the introduction / discharge pipe 2 having both functions of introducing and discharging stored matter at one end of the tank main body 1 as described above, installation work can be performed more smoothly than in the conventional case. In addition, the process can be performed in a short time, and the number of parts is reduced by that much, so that the cost can be reduced. In this embodiment, the first opening / closing damper 34 is provided at the pipe end 32a of the introduction pipe 3, and the second opening / closing damper 43 is provided at the pipe end 42a of the discharge pipe 4. The first opening / closing damper 34 and the second opening / closing damper 43 are closer to the other end portions 32 and 42 than the connection portion between the introduction pipe 3 and the discharge pipe 4 and are in a range that does not hinder the introduction and discharge of the stored matter. If there is, it is also possible to arrange at each intermediate part. The storage tank configured as described above is mounted on, for example, a vehicle and used as a tank vehicle.
Similarly, sludge and the like are sucked and stored through the introduction / discharge pipe 2 by the suction action of the suction device mounted on the vehicle, and are also transported to an appropriate destination and discharged through the same introduction / discharge pipe 2. I am trying to do it. As described above, according to the introduction / exhaust pipe of the stored matter in the storage tank of the present invention, the introduction pipe and the discharge pipe are integrated so that the introduction and discharge of the stored article can be performed. By having the three functions, the mounting operation can be performed smoothly and in a short time as compared with the conventional one, and the number of parts can be reduced correspondingly, so that the cost can be reduced.
