Description

An inhalant in inhalant and remover sludge by using siphon principle}

The present invention relates to an inhaler for sludge suction removal apparatus using a siphon principle, and more particularly, to inhale sludge deposited on a lake bottom corresponding to a fore tank without rising of suspended solids. Sludge deposited on the bottom of the lake can be easily removed by suctioning by the inhaler and transferring it through a siphon pipe to a filter plant with a filtration layer, which is a sewage treatment works installed at a low level. To an inhaler for sludge inhalation removal apparatus using a siphon principle

In general, the siphon conduit principle uses water to be pushed into the hose due to the air pressure acting on the higher liquid level.

At this time, atmospheric pressure is also applied to the lower liquid level, but the force pushing up the water is weak as the pressure of the liquid column having the same height as the height difference h2-h1 of the liquid level.

That is, it is a kind of pipeline that moves water at high place to low place without tilting the container.

Using this principle, it is convenient to move chemicals or contaminants, etc., which avoids contact with air or adheres to objects, and may also transfer only clear liquids floating on the chemicals.

Preferably, for example, the transfer of petroleum from a drum to a small container via a hose utilizes this principle.

In addition, when a farm road crosses a road, a railroad, or a river, it may pass through the bottom of the farm road, and then the flow is converted into a water channel through the flow of the irrigation channel. inverse siphon).

The sludge removal apparatus using the conventional siphon principle is deposited in a sedimentation basin of an artificially produced water purification plant or sewage treatment plant, as described in Korean Utility Model Publication No. 1998-059379 (1998.10.26). A sludge removal apparatus for removing sludge is illustrated in FIG.

Such a device is installed in the sewage basin 100 in the water purification plant and sewage treatment plant to install a submersible bogie 108 to remove sludge, and the oil hole pipe 107 capable of pulling out the sludge under the submersible bogie. 107 'is mounted on the front and rear, and each roll scraper 106, 106' capable of removing sludge deposited on the outside of the front and rear of the perforated pipe, for the time set by the operator. The submersible truck 108 is reciprocated by the electric motor 101 and the traction rope 104 installed on the sedimentation basin 100 while the scrapers 106 and 106 'are rotated horizontally and vertically. Overturned sludge is to be collected.

At this time, the collected sludge is introduced into the perforated pipes 107 and 107 ', and a technical design for discharging to the outside through the flexible pipe 130 by siphon action has been described.

This conventional design technique, the sludge removal apparatus including the submersible cart 108 and the rail 105 that can remove the sludge deposited on the bottom of the sedimentation basin of the artificially refined water purification plant and sewage treatment plant in advance settling basin The scraper 106, 106 'is horizontal and vertical while the subsea vehicle 108 moves back and forth by the electric motor 101 and the traction rope 104 during the time set by the operator. A pull-out apparatus using a siphon action that collects sludge deposited by rotation and discharges it through a perforated drain pipe, which is formed or artificially formed by natural environmental changes. Significant obstacles are involved in the removal of sludge that has been deposited on the sedimentary floors of large lakes and streams.

In addition, it is not possible to install various devices to allow the water truck to reciprocate back and forth, such as a limited water treatment plant and sewage treatment plant, and to collect sludge by the flow of sediment due to the rollover of the scraper in wider lakes and streams. There is a limit.

On the other hand, known techniques that can remove sludge in the sedimentation basin, bridge type (link chain type), wire rope towing type (wire- type) according to the driving-driving mode (draft-driving mode) rope draft type) and the sludge drawing method using a pull-out pipe after transfer to the front manhole hop bar by a scraper movable type according to the slug pull-out method, It is divided into the drawing method of the whole bottom surface in the sedimentation basin using siphon conduit.

The bridge type is a sludge removal device using a scraper and a siphon pipe, and a bridge is installed on the upper part of the sedimentation basin, and the lower part of the sludge collecting the sludge deposited on the lower part of the manhole hop bar ( Manhole hop-bar) and the siphon conduit is installed at the bottom and discharged through the pipe connected to the upper bridge.

However, such a device has a disadvantage in that the equipment cost is high, and the former does not remove sludge at the back of the sedimentation basin, and the latter is uneconomical by drawing low concentration sludge.

In addition, there is a problem in that the scraper can not be operated in a lake or river with a severe bend of the bottom surface.

And, in the link chain type, a composite conveyor having a scraper function while moving the upper and lower parts of the sedimentation basin by continuously attaching sludge removal plates to the chain in order to mainly remove the sediment floating in the sedimentation basin without using a siphon conduit. As a composite conveyor method, it is used in a lot of floats such as sewage treatment plants, which has problems such as corrosion because the chain crosses the atmosphere and the water.

In addition, it is difficult to completely remove the sludge attached to the rear wall of the water purification plant and the sewage treatment plant, and it is not applicable to the inclined slope because the siphon conduit is not used.

The wire rope tow type system is to remove the sludge while the submersible bogie equipped with the deposit removal scraper on the rail attached to the bottom is reciprocated by the towing rope, which is generated when the manual bogie is operated. (2) Due to turbulence and inequality, sludge may not be properly removed due to a decrease in sedimentation efficiency during drawing through the siphon conduit.

In addition, the installation of a sludge removal device such as a rail on the bent floor is inevitably limited.

Conventional sludge removal apparatus as described above is to remove sludge only in artificially formed rectangular sedimentation basin such as a water treatment plant, a water purification plant and a sewage treatment plant, and to remove a sludge deposited on the floor, an underwater truck equipped with a scraper is used. It can be seen that when the sludge is collected by moving to the towing low, the suction is discharged through the siphon conduit.

In addition, although the actual 1998-059379 discloses that a submersible truck can be operated even in an obstacle such as an inclined plate by a control stopper (not shown) and a guide chain (not shown), this is a huge lake formed naturally or artificially. The sludge removal device may not be installed in the water in a place where the curved bottom of the river or the severe curved surface is settled, and the sludge settled due to the obstacle of rotational overturning of the scrapers 106 and 106 'may be collected. In addition, it is very likely that sludge precipitated due to scattering or dispersion of sediment due to turbulence, short-circuit, drift, vortex, and unequal flow is very likely to be re-employed when the scraper-mounted subcarriages are driven.

At this time, even if using a siphon conduit can not be properly sucked and discharged, and also requires a huge facility and auxiliary equipment is inevitably economical.

An object of the present invention for improving this is to raise the sludge deposited on the bottom of the sewage sludge deposited on the surface of a large lake or river that is naturally formed or artificially formed, as well as a water tank, a water purification plant and a sewage treatment plant. SUMMARY OF THE INVENTION An object of the present invention is to provide an inhaler for a sludge inhalation removal device using the siphon principle of activating a siphon action through an inhaler of an inhalation removal device to remove sludge.
