Description

  The present invention relates to a liquid take-out apparatus for taking out liquid from a liquid container, and more particularly, to a liquid take-out apparatus suitable for use in an IBC (Intermediate Bulk Container) container and a container provided with the liquid take-out apparatus.

  As a transport and storage container for various liquids such as chemicals, petrochemicals, solvents, resins, chemicals, food materials, etc., it supports a plastic resin container body and a metal grid that protects the outer surface (top and side surfaces) and the bottom surface. An IBC container including a pallet is used (see, for example, Patent Document 1). The IBC container has a liquid filling port with a lid on the upper surface of the container body, and a liquid discharge valve with an open / close cock at the lower part of the front surface. It is used as a storage container in a factory where liquid is used. In this case, a hose is connected to the liquid discharge valve, and the liquid is transferred to a small container such as a pail can to be used in small portions.

  However, when the liquid is discharged from the lower liquid discharge valve, the pressure due to the liquid weight at the time of full injection is initially applied. Therefore, the liquid is too strong and is scattered around the small container or dust. There was a problem that was easy to mix. Further, for example, a 1000 L IBC container is manufactured for the purpose of an export one-way container. Therefore, when the container is reused, liquid leakage occurs from the packing portion of the liquid discharge bubble deteriorated by the opening / closing operation. Depending on the type of liquid, the asphalt or metal part of the floor that has fallen down from the leaked location will be corroded. Therefore, the useful life of the container itself is about 5 to 10 years, and there is a problem that even if the container can be reused by replenishing the liquid, it is actually difficult to reuse the container.

  As a method not using the lower liquid discharge valve, a method has been proposed in which an internal liquid is discharged through an upper liquid filling port using an electric pump, an air pressure pump, or a manual pump to divide the liquid into small portions. However, subdivision work using an air pressure pump such as an electric pump or a compressor is costly because it cannot be used unless it is an explosion-proof type, for example, at a gas station, and there is no power supply, such as a warehouse where IBC containers are normally stored and installed. However, when it is in a place far from the container, there is a problem that it cannot be used or it is difficult to use because it is necessary to fold a long power cord of about 50 m. In particular, the electric pump may cause a further increase in cost, such as periodic maintenance because it breaks down if foreign matter is present in the liquid.

  Some air pressure pumps do not require a power source by using a nitrogen cylinder or the like. However, air pressure pumps have complicated flow paths and structures, such as pressure management, and pressure resistance is required for each part, and there are also problems such as high costs, and the entire device becomes large and takes up space. . The operation of subdividing with a manual pump has a problem that the operation becomes heavy especially in the case of a liquid having a large specific gravity and viscosity, and the work requires labor and time, and it takes time and effort.

  Therefore, in view of the situation described above, the present invention is intended to solve the problem that the liquid can be taken out without using the lower liquid discharge valve, the container can be reused, and no power source is required. Explosion-proof type expensive parts are not required, it can be realized at low cost, the structure is complicated and large, it can be configured compactly at a low cost, and operation is easy even for liquids with high specific gravity and viscosity Therefore, the present invention is to provide a liquid take-out apparatus that can efficiently perform subdivision work.

  In view of the present situation, the inventor of the present invention first proposed that the liquid in the container is taken out from the upper part of the container through the liquid take-out line by the siphon principle without using the lower liquid discharge valve. Such a method does not require a power source, does not require expensive explosion-proof parts, and can be configured compactly at a low cost without complicating or increasing the size of the structure.

  However, as a result of the experiment, in the case of taking out by the principle of siphon through such a liquid take-out conduit, the momentum of the liquid is difficult to be generated, and the momentum changes depending on the remaining amount of liquid in the container, and the momentum is extremely high depending on the type of the liquid The problem became weak and the liquid could not be removed until the end. On the other hand, when the flow passage cross-sectional area of the liquid take-out pipeline is increased, the initial momentum can be obtained, but the momentum also weakens from the middle, making it easier to suck air from the discharge port side, and the liquid cannot be taken out to the end. The problem that occurred.

  As a result of further intensive studies, the present inventor has increased the force of pulling out the liquid by the gravity of the liquid in the latter part by making the latter part outside the container thicker than the others in the liquid take-out conduit, and the efficiency As well as being able to take out the liquid well, the conduit inside the container becomes relatively thin, so the force to return the liquid to the container side becomes weaker, which can also prevent the suction of air from the outlet side, It was found that it was possible to discharge the liquid to the end without weakening the momentum, and the present invention was completed.

  According to the present invention as described above, the liquid in the container can be taken out through the liquid take-out line by the principle of siphon without using the liquid discharge valve at the bottom, so that the container can be reused. Also, it can be applied to a simple one-way container that does not have a liquid discharge valve, and can be a preferred product in terms of environmental protection (ecology). Also, no power source is required, no expensive explosion-proof parts are required, and an easy-to-use liquid takeout device can be realized at low cost. Further, the structure can be reduced in size and compact without increasing the complexity and size.

  Furthermore, since the flow passage cross-sectional area of the vertical pipe is set larger than the flow cross-sectional area of the inner pipe and larger than the flow cross-sectional area of the horizontal pipe, the vertical pipe having a large flow cross-section The volume of liquid passing through the fluid increases, the potential energy on the discharge side increases, and this increases the force that pulls the liquid due to gravity, which increases the momentum of the liquid flow.

It is easy to use while maintaining flexibility.

  In addition, a liquid injection path that extends upward from the connection site to which the horizontal pipe is connected is provided in the upper part of the vertical pipe, and the upper end of the liquid injection path is the uppermost part of the outer pipe, In the case where a liquid inlet with a lid is provided on the top, the liquid extraction force by the siphon principle acts simply by injecting liquid from the liquid inlet at the start of the first use and filling the pipeline. In addition, even if a situation such as air biting occurs in the middle, the take-out force can be easily recovered by replenishing the liquid from the liquid inlet.

The longitudinal cross-sectional view which shows the usage condition of a container similarly provided with a liquid taking-out apparatus.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  As shown in FIGS. 1 to 3, the liquid take-out device 1 according to the present invention is inserted into the container from the upper part 9 a of the container 9, and an inner conduit 20 that takes in the liquid in the container 9 from the lower end opening 20 c thereof, A substantially reverse U-shaped liquid take-out line 2 comprising an outer line 21 that continues to the inner line 20 extending outside the container 9 and extends to a lower position along the outer wall surface 90 of the container 9 is provided. This is a device for taking out the liquid in the container 9 through the liquid take-out pipeline 2 according to the principle.

  In the present invention, in particular, the flow path cross-sectional area of at least a part of the portion extending downward in the outer pipe 21 (the vertical pipe 211 and the lower pipe 21B described later) is the inner pipe 20. This increases the potential energy on the discharge side, increases the force that pulls the liquid outward by gravity, improves the flow of the liquid, and conversely weakens the force to return to the container side. Suction is also prevented, and the liquid can be taken out efficiently to the end.

  In this embodiment, the container 9 has a liquid filling port 93 with a lid (lid 94) on the upper surface, and a synthetic resin container body 9A having a liquid discharge valve 95 with an open / close cock on the lower front surface; The IBC container includes a metal grid 9B that protects the outer surface (upper surface and side surfaces) and a pallet 9C that supports the bottom surface. However, the present invention is not particularly limited to this. A container having only a filling port (for example, a one-way liquid bag) may be used, and various containers such as a drum can may be used.

  In addition, as for liquids in containers to be taken out, liquids such as various chemicals, petrochemicals, solvents, resins, chemicals, and food materials in which IBC containers are used can be widely applied. .

  Further, in this example, the inner pipe line 20 and the outer pipe line 21 (the upper pipe line 21A and the lower pipe line 21B) constituting the liquid take-out pipe line 2 are pipes having a circular flow section shape. However, the shape is not limited to this, and may be a square, a polygon, an ellipse or other shapes. In this example, only the lower side pipe 21B is a flexible pipe and the others are pipes having a shape-retaining property. However, all of them are flexible pipes, or conversely, all are shaped. It is also possible to use a sex pipeline.

  In this example, as shown in FIG. 1 and FIG. 3, the outer pipe line 21 includes an upper pipe line 21 </ b> A having a shape retaining property that extends along the container outer wall surface 90 to a predetermined position h <b> 1, and the upper pipe line. The lower pipe line 21 </ b> B having flexibility and extending continuously from 21 </ b> A and having a liquid discharge part 25 at the tip part. By combining the shape-retaining upper pipe 21A extending to the predetermined position h1 and the flexible lower pipe 21B extending first from the predetermined position h1, the lower pipe 21B can be easily routed and Therefore, the liquid can be discharged efficiently while maintaining its momentum without being raised excessively.

  Among the outer pipes 21, the above-described upper pipe line 21 </ b> A having shape retention is more specifically, a horizontal pipe line 210 that is continuous with the inner pipe line 20 and extends in the horizontal direction along the container upper wall surface 91. A vertical pipe line 211 that is continuous with the horizontal pipe line 210 and extends in the vertical direction that is the vertical direction along the container side wall surface 92, and is continuous with the lower end of the vertical pipe line 211 and has the above flexibility. A lower pipe line 21B is provided. It is also preferable that the horizontal duct 210 and the inner duct 20, particularly the inner duct 20, be flexible flow paths.

Specifically, a liquid injection path 24 that extends upward from a connection site to which the horizontal pipe path 210 is connected is provided above the vertical pipe path 211, and an upper end portion of the liquid injection path 24 is the liquid injection port 22. It is made into the uppermost part of the outer side pipe line 21 which has. Therefore, by pouring the liquid from the liquid injection port 22, the liquid can be injected into the liquid take-out conduit 2, and the liquid take-out force based on the siphon principle can be easily applied / Can be revived.

  The inner pipe line 20, the horizontal pipe line 210, the vertical pipe line 211, and the liquid injection path 24 are configured by pipes having a shape-retaining property such as a synthetic resin, and the inner pipe line 20 and the horizontal pipe line 210 are L. The horizontal pipe 210, the vertical pipe 211, and the liquid injection path 24 are connected using a T-shaped joint 61. Moreover, the hose which has flexibility, such as a synthetic resin delivery hose containing a reinforcement line, is used for the lower side pipe line 21B. Here, it is preferable that the outer pipe line 21, particularly the vertical pipe line 211, is constituted by a transparent or translucent pipe. Accordingly, it is possible to easily confirm the presence / absence and degree of air biting in the pipe line, the injection amount of the liquid injected from the liquid injection port 22, and the like, which is very convenient.

  The flow passage cross-sectional area of the pipe of the vertical pipe 211 and the flow cross-sectional area of the hose of the lower pipe 21B are both the flow cross-sectional area of the pipe of the horizontal pipe 210 and the flow of the pipe of the inner pipe 20. It is set larger than the road cross-sectional area. Only the flow path cross-sectional area of the pipe of the vertical pipe 211 may be set large, and the hose of the lower pipe 21B may have a flow cross-sectional area similar to that of the horizontal pipe 211 or the inner pipe 20.

  In particular, in this example, the channel cross-sectional area of the vertical pipe 211 and the liquid injection path 24 at the upper end of the vertical pipe 211 is set larger than the channel cross-sectional area of the horizontal pipe 210. At the time of injection, the liquid can be easily poured from the large liquid inlet 22 without using a funnel or the like, and the poured liquid flows to the side of the vertical pipe 211 that is thicker than the horizontal pipe 210. Even if the channel 211 side is efficiently filled with liquid, and the air remains on the side pipe 210 or the inner channel 20 side, the siphon principle of sucking up the liquid in the container acts, and the liquid can be efficiently taken out. .

  A nozzle gun 7 with an opening / closing mechanism is provided as a liquid discharge portion 25 at the tip of the lower side pipe 21B, and a storage box 70 capable of storing the nozzle gun 7 is attached to the outer surface of the container. The liquid discharge part 25 is not limited to providing the gun nozzle 7 as in this example, and is not particularly limited, such as a simple discharge pipe with a cock. The outer pipe 21 is fixed and supported on the outer wall of the container by attaching the pipe of the vertical pipe 211 to the metal grid 9B on the side wall of the container using a binding means 8 such as a wire or a binding band.

  Further, in this example, the inner pipeline 20 is inserted into the container 9 through the lid member 94 of the filling port 93 provided in the container upper wall surface 91, and the inner pipeline 20 is supported by the lid member 94. ing. In the case of having the filling port 93 as in the case of the container 9 of this example, it is convenient to insert the inner conduit 20 through the filling port 93, but the present invention is not limited to this, and is inserted into the upper part of the side wall of the container. A hole may be provided and inserted.

  As described above, according to the container 9 provided with the liquid take-out device 1 according to the present embodiment, as shown in FIG. 3, the liquid in the container can be removed simply by operating the lower pipe 21B and the nozzle gun 7 at the tip. It can be easily subdivided into small containers 5 such as pail cans according to the principle of siphon, and since the discharge valve 95 at the bottom of the container is not used, the liquid can be removed many times and the container can be reused. Is possible. Because it does not use electricity, it is not necessary to use expensive explosion-proof parts or complicated parts, it can be realized with a simple structure and without cost, and contains urea water used for diesel vehicle urea SCR system etc. at gas stations etc. It is suitable for IBC containers.
