Abstract

<P>PROBLEM TO BE SOLVED: To provide a siphon unit coping with overflowing a storage tank through working in such a way that, without notching or perforating the wall of a storage tank, water is rapidly drained through a siphon tube in a permanently maintenance-free manner without using any power pump prior to overflow. <P>SOLUTION: The siphon unit has the following construction and mechanism: Both ends of a siphon tube are provided with stationary auxiliary reservoirs to make a planarly spread W-shaped bent pipe 1, which is adopted as a modified version of the siphon tube. The raised parts of both the sides are so designed that water is ensured to continually run at the W-shaped bent pipe 1 and both of the reservoirs to permanently prevent the breakdown of siphon action. Each time the water level in a storage tank rises over the reservoirs again, increased water is spontaneously rapidly drained via the siphon tube through making use of the action of the resultant water head 3, a combination of a drain pipe 14 and a air pipe 13, and the suction water head 15 of the pipes 14 and 15. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a siphon unit for draining liquid.

  In aquariums, aquaculture ginger, pet shops, etc., fresh water is supplied and drained in sequence by the method shown in the cage (22), notch (23), conduit (24), underground conduit (26) in Fig. 5 Are lined up. This method is the same as draining through the bank of the reservoir of Patent Document 1.

  Siphon of water head (7) when filling the water into the U-shaped curved pipe (6) or hose as shown in B of Fig. 1 when water is discharged naturally through the tank wall without processing holes or holes in the container or tank. There is a method of sucking out by action, and when the size becomes large, as in Patent Document 2, every time the engine is started, a power pump is used to fill and drain water into the siphon tube.

  On the other hand, to use the siphon tube, a siphon tube is used as the outlet pipe of the discharge path as in the measuring device of Patent Document 3, and the molten metal is discharged from the pump house through the check valve in a precise and stable amount. In some cases, the outlet pipe outlet and the molten metal storage tank have the same water level in the container so that the outlet pipe is always filled with molten metal and the residual amount in the outlet pipe is kept constant.

  When drainage pipes are connected to the tank walls of various tanks and aquaculture ginger such as the water conduit (24) and underground water conduit (26) in FIG. 5, the tank walls are inferior in stress dispersion strength and earthquake resistance. In some cases, a siphon tube is used as in the form of Patent Document 2 beyond the above, but the water in the tank is withered in the siphon tube and the water level falls below the siphon tube terminal water level (8) as shown in FIG. When entering, the siphon action was broken, and even if the water level in the tank rose again, there was a problem that it did not flow out by itself.

  The present invention overcomes that problem and is permanent and maintenance-free. Whenever the water level in the tank rises again, unlike the patent document 2, the power pump is used, and unlike the patent document 3, the discharge action by the siphon is used repeatedly. Provide siphon unit to flow out.

Persistently, the liquid in the siphon tube will flow out and air will not enter and will not destroy the siphon action, so an auxiliary reservoir separate from the main reservoir (storage tank) will be at both ends of the siphon tube, and the bottom of the reservoir will be from the siphon tube terminal Low, the wall of the reservoir is higher than both ends of the siphon tube part, and is further attached by the following method so that the siphon tube is always filled with the liquid.
When deployed on a flat surface, it forms a W shape, turns from both ends of the U-shaped siphon tube downward and bends upward to extend the tube, and the extension is used as an auxiliary reservoir.
Moreover, the auxiliary reservoir which opened upwards which inserts each downward U-shaped siphon tube terminal is fixed to both ends of the siphon tube. Alternatively, the auxiliary reservoir is attached by a method in which one end of the W-shaped method is combined with one end of the siphon tube being different.
In this way, even if the liquid level in the storage tank witheres from the end of the siphon tube, the liquid flow through the siphon tube stops at the stage where the head of the liquid in the siphon tube and the liquid in both auxiliary reservoirs is balanced. Permanently prevents the liquid in the tube from running out.
Every time the water level in the storage tank rises from the auxiliary reservoir, the liquid naturally flows out of the storage tank through the siphon tube with the water head pressure corresponding to the rise.

  To drain to an arbitrary position, the auxiliary reservoir outside the storage tank must be connected to the drain pipe, but in the W-shaped method, the upper auxiliary reservoir is bent upward from the upper end of the auxiliary reservoir, and the extension is As a drainage pipe, a hole is formed in the top of the mountain bent part and air is taken in to shut off the water head relationship between the auxiliary reservoir and the drainage pipe. On the other hand, in the auxiliary reservoir method, the auxiliary reservoir in the storage tank Open the side wall of the external auxiliary reservoir at the height and connect the drainage pipe there, and add the wall of the external auxiliary reservoir higher than the connection part so that the liquid does not overflow, and the drainage pipe drains the liquid in the auxiliary reservoir and siphon pipe. Do not break the siphon action.

  Until the liquid in the siphon unit evaporates and loses, it can be drained naturally without maintenance and contributes to energy saving.

  Tanks that use this siphon unit do not drill holes in the tank walls and concentrate stress, and each tank can be made independent without being directly connected to the tank wall with pipes, and the chemical plant tank and chemical tank can be moved to a flat place. They can be lined up, and can continuously drain liquids that are resistant to collapse, collapse, and leakage due to earthquakes and vibrations, contributing to safety.

  Since the siphon is used, the drainage pipe can be easily installed without drilling the existing tank as shown in FIG. 4 compared to FIG.

  By adding an elevating device to the siphon unit, water level control, flow rate control, and metering discharge can be easily and accurately installed.

  Auxiliary sump is provided at both ends of the siphon tube used for drainage by the following method, and when deployed on a flat surface, a W-shaped siphon tube is used. 2 lower and higher than the bends on both sides, and the raised part on both sides is stored. Also, the bottom shown in Fig. 2 is lower than the siphon tube end and the wall is higher than both ends of the siphon tube. The auxiliary reservoir is provided by the method of fixing the auxiliary reservoir of (9) for adding, or by combining one of the methods of the previous W-shaped curved pipe by changing one side, and the water in the siphon tube and the auxiliary reservoir Even if the water level in the storage tank drops below the water level (4) in FIG. 1A or to the water level (12) in FIG. Stop the flow of water The destruction of the phon action is prevented, the syphon action is maintained and maintained forever, and when the water level in the storage tank rises again and the water head (3) in FIG. 1A or the water head (11) in FIG. Allow water to flow naturally out of the storage tank through the tube.

  In order to drain to an arbitrary position, a drain pipe must be connected to the auxiliary reservoir, but as shown in FIG. 3C, a method for providing a pore pipe (13) or a pore hole on the top surface of the drain pipe (14) connection, By connecting the drain pipe (17) to the side of the auxiliary reservoir fixed to the siphon pipe shown in FIG. 3D and providing an opening (16), the water head relationship between the auxiliary reservoir and the drain pipe is cut off, and the suction head of the drain pipe (15) Keeps the siphon action so that the water in the siphon pipe and the water in the auxiliary reservoir are not sucked up by the drain pipe. do.

  The action storage type siphon unit is a glass that can observe the accumulation of air inside the siphon tube without being installed near the liquid or bubble that easily gasifies because the air bubbles in the tube will not function if the bubbles of liquid handled exceed the limit. Use a tube.

  The W-shaped curved pipe (1) in FIG. 1A is called a W-shaped curved pipe because it forms a W shape when deployed on a flat surface, but it is bent within the range that does not destroy the principle as shown in FIG. obtain.

  As shown in FIGS. 6, 7, 8, and 9, the following method is recommended because it can be easily installed at low cost using only pipes. Compared to FIG. 2, a siphon tube having a W shape when deployed on a plane is recommended. Also, in order to connect a drain pipe for draining to an arbitrary position, a simpler connection method of FIG. 3C is recommended compared to FIG. 3D.

  If the pore size of the auxiliary reservoir and drainage pipe connection is too small, the air for cutting off the suction action of the drainage pipe on the siphon pipe cannot enter and the drainage pipe sucks up the water in the siphon pipe. Will not be able to maintain a permanent siphon action.

  Figures 6, 7, 8 and 9 show that this siphon unit has been put into practical use in aquaculture tanks with natural drainage of rainwater, but there are various oils, melts, chemicals other than dams, reservoirs, tanks and tanks, beakers and water. Can be used with melted plastic, melted metal, etc.

  This siphon unit can be used for irrigation water supply between the U-groove without a hole and a water intake and a paddy field because it can be easily installed and removed instead of an engine pump.

  Since the supply amount from the primary tank to the secondary tank can be controlled by adding an elevating device, this siphon unit is used for a liquid material or reagent mixing tank.
