Description

one

The invention relates to a transfusion technique and can be used to unload containers periodically filled with a liquid.

A device for unloading containers periodically filled with liquid is known, consisting of a suction hose and a pump D connected to it.

However, this device does not provide a constant flow rate of the pumped liquid due to a decrease in the height of the liquid layer in the tank.

The closest technical solution to the invention is a device for unloading tanks, periodically filled with liquid, consisting of an intake pipe with slots, a float valve and a pump with a suction rod 2J.

The known device cannot both bake a constant flow rate, since it cannot provide a constant level at the place where the liquid is pumped out.

The aim of the invention is to provide a constant flow rate of a constant level liquid.

The goal is achieved by the fact that in a device for unloading tanks, periodically filled with liquid, consisting of an intake pipeline with slots, a float valve and a pump with a suction hose, a float valve is installed inside the nozzle, and the suction hose is located with a float valve with a gap, while valve height is not less than the height of the nozzle slots.

1 shows the proposed device, a General view {in figure 2, the node t in figure 1.

The device consists of a tank 1, 5 periodically filled with liquid, a suction pipe 2 with a blind end 3, a pump A with a suction hose 5 and a float 6, while slots 7 are formed at the lower end of the pipeline 2 O.

The device works as follows.

The liquid from the periodically filled tank 1 through the slots 7 5 enters the intake pipe 2 and lifts the float 6, which closes the slots. The amount of fluid entering pipeline 2 decreases and completely stops when the slots 7 completely overlap the float 6. Through the hose 5 with the pump 4, the fluid is continuously pumped out of the tank 1. As the float 6 is pumped out, the float 6 goes down and 5 the fluid goes back through the slots 7 suction line 2.

Depending on the desired performance, the float 6 is located at a certain height and the liquid in the pipeline 2 is also set at a certain constant level regardless of the level of the liquid in the tank 1, which is constantly decreasing.

The use of the proposed device will allow an economical effect due to the possibility of simultaneous pumping out and a change in the concentration of the supplied liquid without the use of a mixer.
