However, the above conventional techniques have the following problems. Pumping equipment must be purchased separately from the tank and the equipment that houses the tank.

It is necessary to secure an appropriate place for placing the pump device, and especially for a pump device for a flammable liquid, the place for placing cannot be easily selected.

Forgetting where to put the pump unit,
The supply work may be seriously hindered.

Contamination easily attaches to the pipe body and the supply pipe of the pump device which are exposed when not in use, and the contamination is mixed into the tank and the original tank during use.

After use, the liquid adhering to the pipe body of the pump device and the supply pipe drips, which contaminates the supply work place and causes an offensive odor to be emitted by the liquid.

During the supply operation, it is necessary to continue to monitor the insertion state of both the tube body of the pump device and the supply tube, which complicates the operation.

At the time of attaching / detaching the lid (inlet / out means) of the tank, the liquid adhered to the lid stains the hands and the like, which is unsanitary.

It is necessary to find an appropriate place for placing the lid body (inlet / out means) of the taken-out tank, and dirt may be attached to the lid body depending on the improper placement place.

It is necessary to secure a space in which the tank can be placed near the place where the original tank is installed.

Depending on the mounting location of the tank (state of the mounting surface), the mounting surface of the tank may be damaged.

Depending on the mounting state (mounting surface state) of the tank, the tank may be tilted and a large amount of liquid in the tank may be spilled.

In the supply, the tank must be turned in the forward direction and the reverse direction, which complicates the supply work.

It is necessary to continuously monitor the amount of liquid supplied into the tank, and if this is not done, the liquid will be spilled from the tank.

[0040]

When the pump mechanism descends, the impeller and the casing are brought into contact with each other to stop the pump mechanism, so that the pump mechanism descends into the original tank without performing a pumping action.

When the pump mechanism reaches the bottom surface of the original tank, that is, the inside of the liquid, the casing of the pump mechanism stops descending due to contact with the bottom surface of the original tank. If so, it moves further down.

As a result, the impeller separates from the casing, starts rotating, and opens the hoisting pipe,
The pump mechanism acts as a pump and sucks the liquid in the original tank into the lifting pipe.

The liquid thus sucked up moves up the lifting tube and the support tube and is supplied to the tank body from the outflow port provided at the upper part of the support tube.

When the predetermined supply of liquid is completed,
The motor (spiral rod) is rotated in the direction in which the lifting rod and the lifting pipe are moved upward by the switch mechanism, that is, in the direction in which the pump mechanism is raised.

As a result, the elevating rod and the elevating tube rise, and the impeller and the casing come into contact with each other again, so that the impeller cannot rotate (the pump mechanism is stopped) and the elevating tube is closed. The pump mechanism rises while preventing the liquid from flowing out.

When the pump mechanism has finished rising, the tank device equipped with this pump may be removed from the original tank.

FIG. 15 is a diagram showing a state in which 15 is lowered and the rubber body 16 is separated from the air inlet / outlet hole Ta, that is, a state in which the air outlet hole Ta is opened.

As described above, the opening / closing mechanism 11 allows the air inlet / outlet hole Ta formed in the upper portion of the tank body T to be easily opened / closed by operating the lever L, and controls the air inlet / outlet in the tank body T. You can do it.

Next, the operation of the tank device equipped with the pump having the above-described structure will be described with reference to FIGS.

To supply the liquid into the tank body T, first, as shown in FIG. 7A, the pump mechanism P is inserted into the inlet / outlet port of the original tank 33.

Then, the lever L of the opening / closing mechanism 11 is raised to bring air into and out of the tank body T, and the switch mechanism S
The motor M is rotated in the direction in which the hoisting pipe 3 is lowered by the operation of.

At this time, the pump mechanism P is not driven because the impeller I and the elevating casing C1 are in contact with each other as shown in FIG. Driven by the action of the lift bar 5, the figure (b)
The pump mechanism P is lowered into the liquid in the original tank 33 by advancing the lifting pipe 3 downward as shown in FIG.

When the pump mechanism P comes into contact with the bottom surface of the original tank 33 as shown in FIG. 8A, the elevating casing C1 of the pump mechanism P stops its descending movement, but the elevating means 7 is used.
Further lowers the lifting tube 3 and the lifting bar 5.

As a result, as shown in FIG. 9, the impeller I is separated from the elevating casing C1, the impeller I becomes rotatable, the opening Ca is opened, and the impeller I starts rotating. Then, the pump mechanism P performs the above-described pump action and sucks up the liquid in the original tank 33.

At the time of rotation of the impeller I, the spiral rod 6 and the elevating rod 5 integrally rotate, and a rotary shaft (shaft) for transmitting the drive of the motor M of the drive means A to the impeller I. ) Acts as.

When the pump mechanism P is driven, the locking body 10 provided on the lifting pipe 3 is brought into contact with the upper end of the lifting casing C1 as shown in FIG. ), The positional relationship between the impeller I and the elevating casing C1 can be set to an appropriate position for pumping.

The liquid sucked up by the pump mechanism P rises in the ascending / descending pipe 3 to reach the support pipe 4, and is supplied into the tank body T from the outflow port 8 provided at the upper part of the support pipe 4. To be done. (See Figure 1)

Further, when the liquid is supplied by the pump mechanism P, the liquid sucked out from the small hole H1 formed in the up-and-down pipe 3 flows out, but since the shape of the small hole H1 is smaller than the opening Ca, the pump mechanism P can supply most of the sucked liquid into the tank body T.

After confirming that a predetermined amount of liquid has been supplied into the tank body T through the window 2 provided at the upper portion of the tank body T, the switch mechanism S is operated to move the lifting bar 3 in the upward direction (described above). The direction of rotation of the motor M is changed to (the opposite direction).

As a result, the elevating means 7 moves the elevating tube 3 upward as shown in FIG. 8B by the action of the spiral rod 6 and the elevating rod 5.

When the lifting tube 3 is raised, the pump mechanism P
The elevating casing C1 separates from the original tank 33, and the elevating casing C1 and the impeller I come into contact with each other again.
Is made non-rotatable, and the opening Ca is closed, that is, brought into a stopped state (state shown in FIG. 4), and then raised together with the lifting pipe 3.

Further, when the up-and-down pipe 3 is raised, the liquid in the tank body T flows between the support pipe 4 and the up-and-down pipe 3 through the small hole H2 formed in the support pipe 4. H
Since 1 is projected from the tank body T, the liquid supplied to the tank body T does not flow out to the outside.

When the elevating tube 3 is completely raised, that is, when the lower end of the supporting tube 4 and the locking body 10 are in contact with each other, the small hole H1 formed in the elevating tube 3 causes the liquid in the tank body T to flow. Although it flows into the up / down pipe 3, the liquid in the tank body T does not flow out because the opening Ca of the pump mechanism P is in the closed state as described above.

In this way, after the hoisting pipe 3 is completely lifted, that is, after the driving mechanism A is stopped by the switch mechanism S, the lever L of the opening / closing mechanism 11 is tilted to close the tank body T, and a series of operations are performed. Supply work is completed.

By the way, the opening / closing mechanism 11 causes the air corresponding to the liquid supply to the tank body T to flow out from the inside of the tank body T when the liquid is supplied from the original tank 33, and to open the tank body T after the liquid is supplied. The closed state can prevent the liquid in the tank body T from flowing out.

Further, the lever L of the opening mechanism 11 normally covers the upper side of the switch mechanism S, and
It is possible to prevent unnecessary operation of the.

The liquid supplied into the tank body T is
When the tank body T is set in a predetermined device, the elevating casing C1 of the pump mechanism P is raised by the protrusion 32 (see FIG. 23) provided in the device, and the elevating casing C1 is separated from the impeller I. By doing so, small holes H1 and H2
And is supplied (flowed out) to a predetermined device through the opening Ca.

On the other hand, liquid leakage does not occur from a gap between the vertically movable pipe 3, the vertically movable casing C1 and the like, which are slidably provided, so that more liquid than necessary is not supplied to a predetermined device. In order to prevent the pump mechanism P from being unnecessarily raised, a pipe body may be provided at the lower end of the tank body T to store the pump mechanism P when rising.

As an example, 18 shown in FIG. 10 is a tank body T.
The storage pipe 18 is fixed to the storage pipe 18. The storage pipe 18 is provided so as to store the pump mechanism P that has been moved up to a fixed position as shown in the drawing.

The storage pipe 18 is such that when the liquid supplied from the tank body T to the predetermined device reaches a predetermined height in the device, that is, the lower end of the storage pipe 18 and the liquid in the device are separated from each other. At the same height position, it is possible to stop the outflow of the liquid when the tank body T is closed by the liquid surface.

The storage pipe 18 can prevent unnecessary upward movement of the pump mechanism P caused by accidentally touching the pump mechanism P with the floor or the like, and the tank body T
It is possible to eliminate the outflow of the liquid inside.

Further, the pump mechanism P may be configured to be driven when the lift casing C1 is separated from the impeller I by a predetermined amount.

Reference numeral 17 shown in FIG. 11 is a locking mechanism that allows the impeller I to rotate when the impeller I and the elevating casing C1 are separated from each other by a predetermined amount. The locking mechanism 17 is made of an elastic member. As shown in the figure, one end is fixed to the up-and-down pipe 3, and the tip end portion is biased to the up-and-down rod 5 to prevent the up-and-down rod 5 from rotating.

The elevating casing C1 is provided with a projecting portion Cb projecting upward at a position facing the locking mechanism 17.

Next, the operation of the locking mechanism 17 will be described with reference to FIGS. FIG. 12 is a diagram showing a state in which the impeller I and the like are further descending after the pump mechanism P contacts the bottom surface of the original tank 33 and the descending casing C1 stops descending.

In this state, the opening Ca of the elevating casing C1 is in an open state, but the impeller I cannot rotate due to the urging of the locking mechanism 17 to the elevating rod 5 as shown in the figure. It is in a state.

When the state shown in FIG. 12 is reached, the liquid (not shown) in the original tank 33 flows into the elevating casing C1 so as to flood the impeller I.

FIG. 13 is a view showing a state in which the impeller I and the like are further lowered from the state shown in FIG. 12, and the locking body 10 and the elevating casing C1 are in contact with each other.

In this state, the locking mechanism 17 moves to open outward by contacting the protruding portion Cb of the elevating casing C1 as shown in the figure, and the tip end is separated from the elevating rod 5 to move the impeller I. To be rotatable.

Then, the impeller I starts rotating and sucks up the liquid flowing into the elevating casing C1 by the above-mentioned pump action.

As described above, according to the locking mechanism 17, the impeller I is rotated while being immersed in the liquid, in other words, the pump mechanism P in the stopped state is primed. Therefore, the pump action of the pump mechanism P can be made more reliable.

Further, it is possible to prevent unnecessary rotation of the impeller I when the hoist tube 3 moves up and down, and to ensure the action of the hoisting means 7.

A plurality of arms 20b of the holding body 20 are provided radially like the holding arms 13a of the holding means 13 shown in FIG. 2, and liquid can flow from the gap between the arms 20b. There is.

The holding body 20 holds the lifting bar 5 so as to be rotatable in the horizontal direction, and is lifted and lowered by the circular plates W, W provided on the lifting bar 5 so as to contact the upper and lower surfaces of the holding body 20, respectively. It does not move vertically with respect to the rod 5.

On the other hand, 21 is a locking tube, and this locking tube 21
Is fixed to the support tube 4 so that the lower end thereof faces the upper surface of the holding body 20, and abuts on the holding body 20 when the holding body 20 (lifting tube 3) rises to limit the rising position of the lifting tube 3. You can do it.

The fixed casing C3 is constantly lowered together with the hoisting pipe 3 by its own weight, so that the impeller I
(See FIG. 17), the impeller I cannot be rotated and the opening Ca of the pump mechanism P is closed.

B is a spring body. One end of the spring body B is in contact with the lower end of the holder 20 and the other end is in contact with the hoisting pipe 3,
The fixed casing C3 is urged against the impeller I to make the contact between them more firm.

Next, the operation of the tank device having the pump configured as described above will be described. First, the pump mechanism P is inserted into the entrance / exit of the original tank 33, and the elevating means 7 is driven by the switch mechanism P to lower the pump mechanism P. (Fig. 7
