Liquid overflow device

The proposed technical pemeime relate to the field of engineering and can be used in devices for overflowing liquids from containers.

Known siphon dispenser containing a container with a siphon tube, a valve with a float locking body with a hollow flange mounted on the bottom of the tank and provided with holes on its end surface. The flange is made in the form of an annular element, wrapping a siphon tube and provided with a seal at the lower end. The siphon tube outside the tank is equipped with mechanical type shutoff valves (see A.S. USSR, No. 669092 for 1979, class F 04 F 10/00) /

The disadvantage of this siphon is that it does not have a device for creating a vacuum before pumping fluid from the tank into the siphon tube and the presence of a shut-off aryalura on the siphon tube outside the tank does not allow it to be used when pumping aggressive media due to the rapid failure of the shut-off valves under exposure to aggressive liquid medium and there is no possibility of emptying the siphon tube after transfusion.

A fluid overflow device is also known, comprising: an siphon with a drain elbow connected to a discharge means made in the form of a cylinder with porosity connected to an airtight cavity in the form of a cylinder with a sealed easily destructible diaphragm.

being the bottom of the cavity. The cavity covers the siphon tubes, the outlet, which is located inside this cavity. The cylinder with the piston is moved outside the siphon and creates a vacuum or excess pressure only on the air part of the vacuum. (see A.S., No. 576440, gender C. F 04 F 10/00 for 1977)

The disadvantage of the above device is the complexity of the design and the inability to use it with repeated use. In addition, there is no possibility of filtering the pumped liquid from solid foreign objects and the significant overall dimensions of the entire device.

The silent task of the proposed solution is the design, reliability and the possibility of reusable use of the device when pumping aggressive media.

This task is achieved by the fact that the proposed device for transfusion of liquids containing a container for storing liquid and a container for pouring liquid into it, located below the tank in level, a siphon with a drain elbow connected to a means of creating a vacuum in the form of a cylinder with a piston, means for creating the discharge is set incorrectly inside the tank and is equipped with a valve in the form of an elastic diaphragm, and the piston is equipped with through channels.

Another difference of the proposed device is that the elbow of the siphon is equipped with an expansion chamber, and the entrance to the elbow from the cylinder is made in the form of several holes, the total area of which is not less than the area of the passage section of the siphon hole, and each cylinder hole individually is smaller than the opening of the siphon knee.

The graphic part shows the proposed device, made in accordance with the formula.

As shown in the graphic part, the proposed device contains a container 1 in which the liquid 2 is stored, a container 3, into which the liquid 2 is pumped. A cylinder 4 is installed inside the container 1 with a piston 5 rigidly fixed on the rod 6. The piston 6 is equipped with several through holes 7 and a closed diaphragm 8 mounted on the upper end of the piston 6. From the outside, a siphon elbow 9 with a central hole 10 is rigidly attached and an expansion cavity 11, using a support 12. The side wall of the cylinder 4, at the junction with the elbow 9, is provided with several through holes 13, the diameter of each of which is less than the diameter of the opening 10 of the siphon elbow 9. The inner cavity 14 is cylin Core 4 is open from the bottom of the tank 1 and is not connected with the environment;

The operation of the proposed device is as follows. Before transfusion of liquid 2 from the tank 1, a container 3 is installed under the siphon elbow 9. Then the siphon is started. For this, the piston 5 with the rod 6 together with the diaphragm 8 rises up. Moving inside the cylinder 4, the liquid 2 from the tank 1 fills the cavity 14 due to the discharge pressure inside the cylinder 4. This happens until the holes 13 are opened and the liquid 2 fills the cavity 11 first, and then through the hole 10 begins to flow into the container 3 and fills it. After filling it, the siphon closes and the fluid supply to the hole 10 is stopped. To do this, the piston 5 is moved down inside the cylinder 4. Moving the piston 5 forces due to excess pressure under

bend the diaphragm 8 with the piston, which opens the openings 7 and the liquid from the cavity 14 through the overflow openings 7) enters the cavity above the piston and thereby gives way to the porous movement. This continues until the openings 13 are blocked by porcine 5. After refilling all the openings 13, the supply of liquid 2 to the container 3 is stopped. To resume pumping liquid 2 to 3, it is necessary to move the piston 5 and the process will be repeated. After the movement of the piston 5 downward, the diaphragm 8 under the action of the pressure of the liquid located in the cavity 14 above the diaphragm 8 forces it to press against the end of the piston 5 and closes the holes 7. In the process of pumping fluid from the tank 1 from the space near the bottom, siege is sucked, which is undesirable when pumping. To do this, first, it is carried out by cutting off large solid objects due to the diameter of the holes 13, which do not allow them to pass into the siphon hole 10. After separation of large solid objects, the middle inclusions in the cavity 11 of the siphon 9 are separated and settled by separating them from the flow of moving fluid.

Using the proposed device for transfusion of liquids allows you to place the siphon drive inside the container in which the pumped liquid is located and to exclude the drive without using air. In addition, making holes in the body is smaller than the siphon hole and the expansion chamber at the beginning of the siphon elbow allows you to filter the pumped liquid directly into pumping process without using filtering elements.

The proposed device allows you to get a reliable and small-sized device for reusable pumping of liquid, and compared with the known similar devices to reduce weight by 50%. R1engineer - patent specialist ..-- (sh / w u.I. D. Plekhanov
