Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a pressure water tank tank with a sand removal device for pumping well water, and more specifically, to ground water pumped up by a pump by the action of centrifugal force. The present invention relates to a device for separating sand from groundwater containing sand.

“Prior art” Conventionally, there was no sand remover installed in the pressure water tank for pumping groundwater, and the sand mixed in the groundwater was discharged from the tap water tap as it was. Therefore, another sand remover had to be installed to remove the sand mixed in the groundwater.

[Problems to be solved by the invention] However, installing the sand removing device separately from the pressure water tank has a burden of requiring an installation place and cost of the sand removing device.

An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a device for removing ground water pumped up by a pump in a pressure water tank and supplying only fresh water from a tap.

"Means for Solving the Problems" In order to solve the above problems, the present invention has taken the following means. That is, a lid is attached to the upper part of a cylindrical water tank tank that forms a recess downward, a sand discharge pipe is connected to the tip of the recess, and a dome with a jet hole on the inner wall of the middle part of the water tank. -Shaped partition plate is installed, the injection pipe is inserted from the outer wall to the inner wall of the tank in the lower part of the partition plate, and the drainage pipe and the discharge pipe are inserted above the partition plate from the inner wall of the tank to the outer wall. The above-mentioned problem was solved by projecting it out of the tank and disposing an air valve and a pressure gauge above the water tank.

[Operation] With the above configuration, groundwater pumped from the submersible pump passes through the check valve and enters from the inlet along the inner wall of the lower surface of the dome-shaped partition plate in the lower part of the aquarium tank. , It rotates in a spiral shape along the inner wall of the aquarium tank, and the sand contained in the groundwater sinks downward toward the sand drain pipe. On the other hand, the fresh water in which the sand has settled fills the lower part of the aquarium tank by the water pressure from the inlet, fills the upper part of the aquarium tank from the spout, and goes from the discharge pipe to the tap.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

Each of the drawings shows a pressure water tank tank with a sand removal device for pumping well water according to the present invention. FIG. 1 is a partially cutaway perspective view showing the whole, and FIG. 2 is a sectional view showing the water tank tank. .

First, a thin sand discharge pipe 2 is attached to the tip of the recess of a water tank tank 1 having a cylindrical shape and forming a recess downward, and then a lid 3 is attached to this water tank tank 1. The lid 3 may be screwed or welded. Furthermore, this aquarium tank 1
A dome-shaped partition plate 6 having a diameter matching the inner circumference and having a jet port 5 is attached to the inner peripheral edge of the water tank tank middle portion 4. This partition plate may be welded or screwed. Next, in the lower part 7 of the aquarium tank, the injection pipe 1 is directed toward the inner wall 9 and the injection port 1
Attach it to 0. The injection pipe 8 has a check valve 11 provided in the pipe.
Is provided. The injection pipe 8 is connected to a submersible pump 12, and a water absorption pipe 13 connected to the submersible pump 12 reaches groundwater (not shown) under the ground.

On the other hand, a partition plate 6 is provided on the upper part 14 of the aquarium tank 1.
The drainage pipe 15 is attached near the upper surface of the
A pressure gauge 18 including a water discharge pipe 16 for sending fresh water to a tap of a water pipe, an air valve 17, and a pressure switch (not shown) is attached to the upper part of the device 5.

Due to the above-mentioned configuration, in order to remove sand from groundwater using the pressure water tank tank 1 with a sand removal device of the pumping well water of the present invention, groundwater pumped by the submersible pump 12 through the water suction pipe 13 Through the injection pipe 8 and the injection port 10
It is poured along the inner wall 9 of the lower part 7 of the aquarium tank.

The groundwater injected into the lower part of the aquarium tank 7 is the lower part of the aquarium tank 7.
While being swirled along the inner wall 9 of the tank, the water tank is filled from the bottom of the lower part 7 to the upper part in sequence. Groundwater is always an inlet 10
Is injected along the inner wall 9 from the bottom of the aquarium tank 7
The water in the vortex swirls, and the force of centrifugal separation works, and the sand 19 heavier than water gathers at the center of the vortex, and the sand discharge pipe 2 due to its own weight.
It is dropped with a small amount of water toward and is discharged to the outside of the water tank tank 1 through the sand discharge pipe 2.

On the other hand, the fresh water 20 filled in the lower part of the water tank tank 7 is ejected by the water pressure from the ejection holes 5 formed in the partition plate 6, flows into the upper part 14 of the water tank tank, and the collected fresh water 20 is collected by the air valve 1
Air pressure is applied by 7 and the water is sent from the water discharge pipe 16 to the tap of the water supply.

[Advantages of the Invention] As is clear from the above description, according to the pressure water tank tank with the sand removing device for pumping well water of the present invention, it is necessary to separately install the pressure water tank and the sand removing device as in the conventional case. There is a great advantage that it can be eliminated, the installation place can be saved, and the installation cost can be reduced.
