Abstract

PROBLEM TO BE SOLVED: To provide a liquid discharging apparatus with a liquid level gauge which is detachable and can be used for a general upper part open type vessel, can directly recognize a variation amount of a liquid level in a can during storage and discharge, has a simple structure, is easily handled, and high in safety.SOLUTION: A discharge siphon circuit and a display siphon circuit are formed, and liquid 2 in a drum can vessel 1 placed on the floor is delivered from a discharge port of an intermediate discharging unit 16. A float 20 floating in a liquid level display tube (transparent tube) 13 at the outside of the tube displays the liquid level of the inside of the tube. When a position of the discharge port of the intermediate discharging unit 16 is higher than the surface position of the liquid at the inside of the tube, the liquid cannot be discharged only by a gravity system, and therefore, by pressurizing the inside of the can by a hand-held pressurizing pump 23, the liquid 2 is pumped, and can be discharged to the outside of the can. Furthermore, the liquid 2 can be discharged to the outside of the can by attaching an electric small pump 37 on a distal end of a discharge siphon tube (can inner part) 7 and pumping the liquid 2.

Description

  The present invention can easily discharge the liquid stored in an upper open container such as a drum can, a pail can, a one-eyed can, and the like, and can directly read and recognize the liquid level in the can from the outside. The present invention relates to a liquid ejection device with a level gauge that can be attached to and detached from an upper open container.

Conventionally, when liquid is subdivided from a top open type container such as a drum can, a pail can, a dough can, etc., an electric pump or a hand pump is used, a faucet is attached to the discharge port, and the can body is laid sideways or discharged, or A method is adopted in which the inside of the can is sealed and discharged under pressure. The following means are used to check the remaining amount of liquid in the can and the discharge amount, but each has the following problems.
(A) There is a means for making a hole on the outside of the container, and attaching a liquid level gauge here to visually measure the liquid level in the container (see, for example, Patent Document 3). In order to apply this means, it is necessary to transfer the liquid in the can to a dedicated tank, which is very laborious and time consuming. Furthermore, there are problems such as high installation costs and the need for installation space. When a can is attached to the discharge port of the can and the can body is laid sideways, the discharge port and the liquid level gauge are integrated. The position cannot be displayed. In addition, the entire can must be laid down, a dedicated laying device is required, and handling is difficult. Furthermore, there are many problems in accuracy, workability, safety, installation costs, etc., because it is necessary to fix the entire can for safety.
(B) In many cases, the discharge device and the liquid level display device are separately installed and used. In order to know the amount of liquid in the can, various detachable liquid level gauges are used. Typical examples include a float type, a gravimetric type, a capacitance measurement type, and an atmospheric pressure type (see, for example, Patent Documents 2 and 5). However, since these liquid level gauges require a special structure, circuit, and equipment to check the amount of liquid in the can, the handling is complicated and the manufacturing cost is high. Moreover, it cannot be said that the measurement accuracy is sufficient.
(C) There is also a siphon type detachable liquid level indicator (for example, see Patent Document 1). However, there are difficulties in practical use. In this method, when the liquid inside the can is drawn up to the liquid column meter outside the can, bubble turbidity is likely to occur in the pipe pipe on the way, and an accurate siphon pipe can be formed due to bubble accumulation at the upper end of the pipe. Absent. Accordingly, the accuracy of accurate liquid level display outside the can is poor. In addition, there is a subtank system using siphon (for example, see Patent Document 4). However, in order to perform subdivision, the subtank must be used each time, and the structure is complicated and difficult to operate. In addition, there is a circuit switching type in which a three-way cock is combined with a siphon (see, for example, Patent Document 6). However, in this method, it is not possible to know in real time the amount of change in liquid in a can container during subdivision discharge. There is a problem.

And a display siphon tube (transparent inverted U-shaped portion) 11.

  The present invention includes a discharge tube group, a display tube group, a circuit switching valve, and a discharge valve for forming two siphons. The structure is simple and compact, and handling workability is easy. In addition, since the structure is simple, there are few failures and it can be manufactured at low cost. As for the accuracy of the liquid level, it is possible to directly read the change in the liquid level during sub-discharge without interposing an electric signal or drive mechanism, and it is highly accurate. In addition, since the device is compact, it is easy to attach and detach, and does not require a drive source or requires a small drive source. Therefore, for general portable containers such as drums, pail cans, and funnels, It can be used in places and is very convenient. In addition, the use of the coupling device can simplify the replenishment of the liquid and can be used as a large-capacity container by using many of them, which is highly convenient.

  It is structural sectional drawing at the time of installing this invention in a drum can.   This is an embodiment in which a pail can or a canister can be lifted and installed on a table.   FIG. 2 is a sectional view of the structure when operating the discharge pump in FIG. 1.   FIG. 4 is a structural cross-sectional view when the liquid level height in the can in FIG. 3 is confirmed with a display tube.   It is a structure sectional view at the time of a discharge siphon state with a double acting suction pump.   FIG. 6 is a structural cross-sectional view when the display siphon circuit is completed in FIG. 5.   FIG. 7 is a sectional view of the structure when the suction pump is removed from FIG. 6.   It is structural sectional drawing at the time of connecting the container which applied the double acting suction pumping pump shown in FIG.   FIG. 9 is a structural cross-sectional view in the case where confirmation is made with a display tube in FIG. 8.   It is a use condition figure of a connection unit.

  The discharge device with a detachable liquid level gauge makes it possible to attach and detach to the upper open container by making two siphon circuits that apply the siphon principle, and to perform subdivided discharge that does not require power, and the liquid level in the can It enables direct reading and recognition from outside the tube with high accuracy.

  In order to discharge and display the liquid in the can outside the tube, it is necessary to form two siphon circuits, a discharge siphon tube group and a display siphon tube group. The method of forming a siphon circuit is a method of sucking and pushing the liquid with a pump, a method of sealing the inside of the can container and pumping the liquid by applying high pressure, and a method of sucking the liquid by making the display can part into a negative pressure state with a suction pump A method of pumping with a small pump can be considered. The present invention forms a subdivision discharge circuit and a liquid level display circuit, discharges the liquid in the can, and enables the liquid level height in the can to be directly read and displayed in real time with a transparent display tube outside the can. Features.

  Since the circuit switching valve creates two independent circuits, a discharge siphon circuit and a liquid level display siphon circuit, the liquid level display tube is completely affected by the discharge even though the discharge port and the display tube are adjacent to each other. In addition, the liquid level inside the can during discharge can be accurately displayed on the liquid level display tube outside the can in real time.

  By providing a discharge valve in the discharge siphon circuit, the liquid in the can can be safely discharged out of the pipe while being placed vertically without tilting the can, and the workability of replacing the liquid is improved.

  In the liquid level display mechanism of this apparatus, it is important that the siphon circuit is reliably formed. Bubbles in the siphon circuit should not be present because they give an error in display accuracy. Therefore, in order to confirm that there are no bubbles in the siphon tube, a transparent inverted U-shaped tube is provided on the upper part of the two siphon tubes to facilitate the presence / absence check of the bubbles. As a result, it is possible to realize an accurate liquid level display without error and to eliminate the influence of bubbles and to perform quick and reliable sub-discharge.

  By floating the float inside the display tube and irradiating the LED light from above the display tube, the liquid level display can be made clear. In addition, when the float is formed of a magnetic material, the display liquid level can be taken out as an electric signal by installing a magnetic detection device or the like outside the tube, and can be applied to various controls. In particular, since the detection device is outside the tube, the detection position can be easily changed.

  Open top and sealed portable containers such as drums, pails, and Ito cans often handle flammable liquids and toxic gases. In these cases, it is important not to release the gas out of the can. Further, if the display tube part and the atmospheric pressure in the can are different, accurate liquid level display cannot be performed. For this reason, the space above the liquid level above the display tube and the space above the liquid level in the can are connected by a pipe. As a result, the external space is shut off, safety can be ensured, and the can internal pressure and the display tube internal pressure become the same pressure, thereby ensuring the liquid level display.

  When discharging from the upper open container only by gravity using a siphon, it is possible to discharge even the lowest liquid in the container by installing the discharge port below the lowermost surface of the container. However, the entire can needs to be installed above the container receptacle. If it can be lifted by hand, such as a pail can or a funnel, it can be lifted and installed relatively, but it is difficult for a large container such as a drum can to lift and install. Therefore, by increasing the pressure in the can using a pressure pump from the drum can opening and pumping and discharging at that pressure, it is possible to discharge to the lowest bottom surface of the container while the container is still installed on the installation floor. . Further, by providing a small electric pump at the liquid suction port and pumping the liquid, it is possible to discharge to the lowest bottom surface of the container with less power.

  By connecting the cans with a connected siphon device using a suction pump system from the display tube side as an accessory device, liquid movement between the cans is possible without using power. For this reason, even if the main unit is in use, the liquid can be continuously supplied without removing the main unit from the can. Further, when a large number of accessory devices are used in succession, a large number of cans installed arbitrarily can be used as a single container with a large capacity. If the main unit is installed at key points, it is possible to install an arbitrary number of discharge ports. If a large amount of liquid is urgently needed, or a large amount of water is stored during a disaster, etc. It is a very effective means for emergency response that requires Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 (a) is an installation example when the apparatus is large like a drum can and cannot be easily transported by humans, and is installed in the drum can container 1 and a discharge siphon circuit and a display siphon circuit are formed. Is shown. The state in which the liquid 2 in the drum placed on the floor is discharged from the discharge port provided in the middle discharge unit 16 is shown. At this time, the float 20 floating in the liquid level display tube (transparent tube) 13 outside the tube directly reads the liquid level inside the tube. When the position of the discharge port of the middle discharge unit 16 is higher than the surface position of the liquid 2 inside the pipe, it becomes impossible to discharge only by the gravity method. 2 can be pumped out of the can. Further, as shown in FIG. 5B, it is possible to discharge the liquid 2 outside the can by attaching an electric small pump 37 to the tip of the discharge siphon tube (inside the can) 7 and pumping the liquid 2. . FIG. 2C is an enlarged view of the lower circuit switching unit 14. The arrows in the figure indicate the direction of liquid movement.

  FIG. 2 shows an example of installation when the apparatus can be carried by a person such as a pail can or a canister 26 and can be installed on a table relatively easily. In this case, by installing the pail can or the canister 26 on the stand, the discharge port of the middle discharge unit 16 of the present apparatus can be set at a position lower than the bottom of the can, so that the liquid 2 can be removed only by gravity. The pail can or the canister 26 can be discharged to the bottom.

  1 to 7 includes three discharge siphons including a discharge siphon tube (inside the can) 7, a discharge siphon tube (transparent inverted U-shaped portion) 8, and a discharge siphon tube (outside of the can) 9. Four display siphons comprising a tube group, a display siphon tube (inside the can) 10, a display siphon tube (transparent inverted U-shaped portion) 11, a display siphon tube (outside of the can) 12, and a liquid level display tube (transparent tube) 13 It consists of a tube group, a suction pump type or pump compressed air type lower circuit switching unit 14, and a middle discharge unit 16.

    FIG. 3A shows that the circuit switching valve 15 of the lower circuit switching unit 14 of this apparatus is inserted into the drum can container so that the display siphon tube opening 15b and the discharge siphon tube opening 15c are connected, and then the suction pump 6 The liquid 2 is sucked up from the discharge siphon tube (inside the can) 7, or the liquid 2 is pumped to the discharge siphon tube (inside the can) 7 by the electric small pump 37, and the discharge siphon tube (transparent inverted U-shaped tube) 8 Through the discharge siphon tube (outside of the can) 9 and from the discharge siphon tube opening 15c of the circuit switching valve 15 of the suction pump type or pump compressed air type lower circuit switching unit 14 to the display siphon tube opening 15b The display siphon tube (outside of the can) 12 passes through the display siphon tube (transparent inverted U-shaped portion) 11 to the display siphon tube (inside of the can) 10. Returning the liquid to the can body 2 is pumped, there in a state diagram to complete the display siphon circuit and a discharge siphon circuit. At this time, it is important to confirm that there is no bubble accumulation in the display siphon tube (transparent inverted U-shaped portion) 11. If there is a bubble pool, the float 20 in the liquid level display tube (transparent tube) 12 is affected by the bubble pool when the liquid 2 is discharged out of the can and displays a higher liquid level than the liquid level in the tube. Further, when the liquid 2 is refilled in the can, it is not possible to display a normal liquid level in the pipe by displaying a lower level than the liquid level in the pipe. The larger the bubble pool, the greater the effects and errors that occur, so it is necessary to eliminate the bubble pool. Therefore, when there is a bubble pool, the suction pump 6 is operated again to suck up the liquid 2 again from the discharge siphon tube (inside the can) 7 and send it to the discharge siphon tube (outside the can) 9. At this time, the discharge siphon tube (outside of the can) 9 and the display siphon tube (outside of the can) 12 contain the liquid 2 having no bubble accumulation. By sucking up the liquid without bubble accumulation and operating the pump 6, the liquid is sent to the display siphon tube (transparent inverted U-shaped portion) 11, and the bubble accumulation portion is discharged into the drum can container 1 through the display siphon tube (inside the can) 10. I can do it. By these operations, a display siphon circuit group having no bubble accumulation can be reliably formed. In the discharge siphon circuit group, since there is a tendency for the discharge speed of the liquid 2 to decrease if there is a bubble accumulation, it is desirable to eliminate it as much as possible. FIG. 2B is an enlarged view of the lower circuit switching unit 14. The arrows in the figure indicate the direction of liquid movement.

  Thereafter, as shown in FIG. 4 (a), the circuit switching valve 15 of the lower circuit switching unit 14 is switched to connect the liquid surface display tube opening throttle portion 15a and the display siphon tube opening 15b, whereby the liquid surface display tube. (Transparent tube) 13 shows a state in which the liquid 2 has flown and the float 20 is pushed up to display the liquid level in the can. In this state, the ejection siphon circuit and the display siphon circuit are completely independent of each other, so that they do not interfere with each other. Therefore, the float 20 can accurately display the liquid level in the can in real time as the liquid 2 is discharged. FIG. 2B is an enlarged view of the lower circuit switching unit 14. The arrows in the figure indicate the direction of liquid movement.

  Moreover, the LED light emitter 22 is attached to the uppermost part of the liquid level display tube, and the upper surface of the float and the contact surface with the liquid are illuminated by irradiating the float 20, and the liquid level is clearly recognized even in the dark. It is possible to do.

  In the case of a floor-standing system such as a drum can, when performing subdivided discharge to the receiving container 5, the position of the discharge valve 17 is located above the bottom surface of the drum can container 1. For this reason, the liquid 2 at the same position or lower height as the discharge valve 17 cannot be discharged only by the siphon principle. In order to discharge these liquids 2, a hand type pressure pump 23 is attached to the air hole 4 of the drum can container 1 to pump outside air, pressurizing the pressure inside the can above atmospheric pressure, and a discharge valve. By opening 17, the liquid 2 in the can can be received and divided into containers 5. Further, the liquid 2 can be discharged from the discharge valve 17 by driving the electric small pump 37 attached to the tip of the discharge siphon tube (inside the can) 7.

  FIG. 5A is a state diagram in which two siphon tube groups are created from the liquid level display tube (transparent tube) 13 using a suction / pressure feed pump. The circuit switching valve 15 of the suction / pressure pump type lower circuit switching unit 14 of this apparatus is set so that the liquid level display pipe opening throttle part 15a and the discharge siphon pipe opening 15c are connected, and this apparatus is installed in the drum container 1. The suction port side of the double-acting suction / pressure feed pump 31 is connected to the coupler connection port 30 for suction. In this way, the liquid 2 in the can is sucked up from the discharge siphon tube (inside the can) 7, passes through the discharge siphon tube (transparent inverted U-shaped tube) 8, passes through the discharge siphon tube (outside the can) 9, From the discharge siphon opening 15 c of the switching valve 15, the liquid 2 is sucked up to a little lower position where it does not flow into the upper coupler connection port 30 of the liquid level display tube (transparent tube) 13 through the liquid level display tube opening throttle portion 15 a. In this state, the discharge siphon circuit is completed. FIG. 2B is an enlarged view of the lower circuit switching unit 14. The arrows in the figure indicate the direction of liquid movement.

  FIG. 6A is a state diagram in the middle of making a display siphon circuit by returning the liquid 2 from the liquid level display tube (transparent tube) 13 into the drum can 1. When the state shown in FIG. 5 is reached, the circuit switching valve 15 is switched so that the liquid level display tube opening throttle 15a and the display siphon tube opening 15b are connected. At the same time, the double-acting suction / pressure feed pump 31 is removed once, the pressure feed port side is connected to the coupler connection port 30, and compressed air is fed into the liquid level display tube (transparent tube) 13. As a result, the liquid 2 drawn up by the liquid level display tube (transparent tube) 13 and passed through the display siphon tube (outside of the can) 12 through the circuit switching valve and the display siphon tube (transparent inverted U-shaped portion) 11. The liquid 2 is fed into the can from the display siphon tube (inside the can) 10 via. At this time, if there is no bubble accumulation in the display siphon tube (transparent inverted U-shaped portion) 11, the display siphon circuit is completed. FIG. 2B is an enlarged view of the lower circuit switching unit 14. The arrows in the figure indicate the direction of liquid movement.

The important thing here is to reliably form the display siphon tube group. If there is a bubble pool in the display siphon tube (transparent inverted U-shaped portion) 8, the liquid level height of the liquid level display tube (transparent tube) 13 due to the bubbles when the liquid 2 in the can is discharged as described above. The correct liquid level cannot be obtained. Therefore, in order to form a reliable display siphon tube group, it is necessary to consider the following items.
(A) The volume capacity of the liquid level display tube (transparent tube) 13 is as follows: circuit switching valve 15, display siphon tube (outside of can) 12, display siphon tube (transparent inverted U-shaped portion) 11, and display siphon tube (inside of can) ) Must be greater than 10 total tube volume capacity. The larger the capacity, the more liquid 2 sucked up from the liquid level display tube (transparent tube) 13 to the display siphon tube (outside of the can) 12, the display siphon tube (transparent inverted U-shaped portion) 11, and the display siphon tube (inside the tube) When the siphon state is created by reverse pressure feeding to 10, the liquid 2 without bubbles can be reverse pressure fed with a margin, and a correct siphon circuit is formed.
(B) When the liquid 2 is sucked up from the inside of the pipe, a bubble accumulation is likely to occur in the discharge siphon pipe (outside of the can) 9 due to bubble turbidity. In order to solve this problem, the inner diameter of the liquid level display tube (transparent tube) 13 is made larger than the inner diameter of the display siphon tube (outside of the can) 12. Alternatively, it is important to provide a display siphon tube opening 15b in which a throttle part is provided in the circuit switching valve 15 of the connection part. As a result, fine bubbles can be formed at the moment when the liquid 2 containing bubbles flows into the liquid level display tube (transparent tube) 13, so that the bubbles can easily disappear on the liquid level of the display tube. By filling the liquid level display tube (transparent tube) 13 to a sufficient height and feeding it in reverse pressure, a correct siphon circuit can be formed.
(C) The display siphon tube (transparent inverted U-shaped portion) 11 must be able to confirm bubbles using a transparent tube. When bubbles are found, it is important to redo again and eliminate the bubbles.

  FIG. 7A is a state diagram in which two siphon circuits are completed, the liquid level in the can can be confirmed with a display tube outside the tube, and the liquid is discharged from the discharge port. In the state of FIG. 6, when it is confirmed that the display siphon circuit is completed, the double-action suction / pressure feed pump 31 is removed from the coupler connection port 30. Thereafter, the atmospheric pressure tube 29 is connected to the coupler connection port 30 as shown in FIG. As a result, the internal pressure of the can drum 1 and the internal pressure of the liquid level display tube (transparent tube) 13 are the same, the liquid level is the same, and the accurate liquid level inside the tube can be directly read from outside the tube. Further, when the discharge lever 18 of the middle discharge unit 16 is pressed, the discharge valve 17 is opened and the liquid 2 can be discharged. FIG. 2B is an enlarged view of the lower circuit switching unit 14. The arrows in the figure indicate the direction of liquid movement.

  FIG. 8 is an installation state diagram of the connecting unit 32 that connects the cans to each other and can move the liquid in the pipe to another pipe by using only the atmospheric pressure or the pressurized pressure without using power. The basic configuration of this unit employs a method of forming a siphon tube state using a double-action suction / pressure feed pump 31 shown in FIG. 8 is inserted and set into the drum container 1 having a different internal capacity, and then the liquid level display tube (transparent tube) 13 is connected to the coupler. The suction port of the double-action suction / pressure feed pump 31 is connected to the port 30. By operating the pump, the liquid 2 from both cans is sucked up through the connecting liquid guiding pipe 33 and sucked up to the upper part of the liquid level display pipe (transparent pipe) 13 through the display siphon pipe (transparent inverted U-shaped portion) 11. The state is shown. At this time, the liquid 2 in the can has spread to all the tubes constituting the siphon tube, and the siphon circuit of the can and the can and the can and the liquid level display tube is completed.

  In FIG. 9, the double-acting suction / pressure feed pump 31 is removed from the coupler connection port 30 of the liquid level display tube 13 in the above state, and then the insertion port of the connected atmospheric pressure tube 35 is inserted into the coupler connection port 30. Indicates the state. The connection state of the two drum cans 1 by the connection unit 32 is completed, the liquid 2 is moved, the liquid level in the cans of the two drum cans 1 is the same, and the liquid level is outside the tube. Can be visually confirmed with the liquid level display tube (transparent tube) 13 of the simple discharge device with detachable liquid level gauge and the liquid level display tube (transparent tube) 13 of the connecting unit.

  FIG. 10A shows an embodiment in which a plurality of cans are connected by using a large number of connecting units to create a large-capacity container. FIG. 4B shows an embodiment in which a plurality of simple devices with detachable liquid level gauges and a connecting unit of an accessory device are combined, and a plurality of discharge ports are installed from a large-capacity container. As can be seen from this embodiment, by combining the apparatus and the accessory apparatus with a plurality of upper open containers, it is possible to easily create a storage state comparable to a large-capacity large container according to the required capacity. In addition, any number of discharge ports for dispensing can be easily installed by inserting the apparatus into the upper open container. In particular, it is an effective means for securing water in the event of a disaster, and for storing liquids whose supply and storage capacity vary greatly.

  By making the discharge siphon tube (inside the can) 7 and the display siphon tube (inside the tube) 10 inserted into the inside of the can into flexible tube tubes, other than upright open containers such as drum cans, pail cans, and canisters Since this apparatus can be applied to a deformable upper open container, its application range is wide.
