BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a groundwater dust remover for removing sand, foreign matter, etc. contained in groundwater.

[0002]

2. Description of the Related Art Conventionally, groundwater has been pumped up to remove snow accumulated on the ground or on a building with a snow-discharging nozzle, and to sprinkle fields with a sprinkler. However, if the groundwater contains sand or foreign matter at that time, the tip of the snow-melting nozzle or the sprinkler sprinkler hole may be blocked by foreign matter or corroded by sand, making it unusable. There are many.

Therefore, for example, a screen portion is provided in a pipe between a groundwater pump and a nozzle or a sprinkler to trap sand and foreign substances, or a cyclone for liquid is provided to remove sand or sand contained in groundwater. Although foreign substances are removed, if a screen is used, sand and foreign substances captured by the screen will accumulate on the upstream side close to the screen, clogging the screen and making it impossible to pass water, so it will be included in the groundwater. Depending on the amount of sand and foreign matter, it was necessary to frequently replace the screen and remove the sand and foreign matter accumulated in the tube. When a liquid cyclone is used, groundwater tangentially flowing into the cylinder above the cyclone swirls inside the cylinder,
Foreign matter having a greater specific gravity than water, such as sand and foreign matter contained in groundwater, is swung along the inner wall by the action of centrifugal force and then descends toward the lower cone, causing the sand to settle at the bottom of the cone to form a sediment. Groundwater from which foreign matter and foreign substances have been removed gradually turns into an upward flow near the center in the conical portion and is led out to the snow-melting nozzle and sprinkler from the central vertical conduit in the upper part of the cylinder. Therefore, inside the cyclone, the outer vortex swirls and horizontal type separation is performed to settle solid matters such as sand and foreign substances downward, and in the central part of the lower half of the cone, it is reversed to perform upflow type separation. In the actual cyclone, it is difficult to avoid the generation of swirl flow, which significantly hinders the dedusting action. I had to design a cyclone, and it was very difficult to get a proper cyclone.

According to the present invention, groundwater is pumped into a spiral water pipe arranged in a pressure tank, and sand or foreign matter contained in the groundwater is jetted out by using centrifugal force on the side surface of the water pipe. It is a technical subject to provide a groundwater dust removal device that can be removed from some parts.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

Ground water pumped by the pump a is fed into a spiral water pipe 2 arranged in a pressure tank 1, and a fountain portion 3 is formed through a side surface of the water pipe 2 on which centrifugal force acts.
The present invention relates to a groundwater dust remover characterized in that a sand sediment discharge section 4 is provided below a pressure tank 1.

The opening of the fountain portion 3 is formed in a hole 3'or a slit 3 ", the opening width is restricted to about 1 mm, and a small hole 5 is formed on the opposite side. Related to the groundwater dedusting device.

The operation of claim 1 will be described.

When the ground water is pumped into the spiral water pipe 2 arranged in the pressure tank 1 by the pump a, the ground water of the mixture having a larger specific gravity than the water contained in the ground water, such as sand and foreign matter, has a spiral shape. Due to the centrifugal force generated when the water pipe 2 is swirled, it is jetted together with the groundwater from the fountain part 3 of the water pipe 2 into the pressure tank 1, and the jetted sand and foreign substances are deposited and discharged at the bottom of the pressure tank 1. The groundwater discharged from the part 4 and from which the inclusions such as sand and foreign substances are removed are spiral water pipes 2
It is led to the snow-melting nozzle and sprinkler from the upper part of.

The operation of claim 2 will be described.

Since the opening shape of the fountain part 3 is formed by the hole 3'or the slit 3 "and this opening part is regulated to about 1 mm, the mixture of sand and foreign matters of about 1 mm or less contained in the groundwater is groundwater. Is spouted into the pressure tank 1 together with the groundwater from the spouting portion 3 due to the centrifugal force generated when swirling in the spiral water pipe 2.

Further, at this time, since the small hole 5 is formed on the opposite side of the ejection portion 3, when sand or foreign matter is ejected from the ejection portion 3 into the pressure tank 1 by centrifugal force, it is accumulated in the pressure tank 1. Sucked water is sucked in through the small holes 5 to facilitate the spouting of sand or foreign matter from the spouting part 3.
