Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to drying devices, and more particularly to the problem of removing liquid from areas of the ground where it has spread.

BACKGROUND OF THE INVENTION The need to quickly and efficiently remove liquids that cover large areas of the ground is well known. After heavy rain, the golf course's grass, Krickerato St. and tennis courts are unplayable.

Equally common, and potentially very dangerous, is the prompt cleaning up of large puddles of fuel oil or other chemical fluids spilled onto highways from transport tank cars;
This is generally not possible.

The easiest way to clean up such liquids is to use a large number of personnel to sweep them from the ground where they are flowing. This method is generally time consuming and necessarily expensive.

Another method, which is sometimes used, is to use the downdrafts produced by the rotors of one or more hovering helicopters to disperse the water as a mist in an attempt to vaporize large pools of water. There is. This method is expensive for its effectiveness, and its efficacy is questionable.

Devices have been developed that attempt to solve this problem.

One such device is known as MOTOMOF. This device is currently manufactured and sold by Motomop Ltd., Cressetund 2, Taunton, Somerset, TAj 4ICA, UK. This device is a driven machine that moves on ground wheels and propels a large rotating sponge. The sponge is adapted to cover a flooded area of a grassed sports field. The water collected by the sponge is temporarily stored in the device's tank and then piped out of the device.

(Problems to be Solved by the Invention) However, the above-mentioned device has the drawback that the sponge wears out and the sponge must be replaced periodically. Another omission is that the weight of the device, combined with that of collected and stored water, causes the wheels of the device to sink into the soggy grass field, thus compensating the ground.

Yet another drawback is that although this machine has been developed specifically for cleaning water from grassed sports fields, it is unclear whether it can be applied to other surfaces as required.

SUMMARY OF THE INVENTION A machine according to the invention for removing liquid from areas of ground where it has spread comprises:
A hood that forms the top and sides of the water remover when in use, a tray that is almost flat and has an opening in the center, and a
l A device having a tray mounted inside the hood to form the lower part of the dewatering machine in use, and an annular gap maintained between the periphery of the tray and the hood; A motor-driven fan that is installed in the center and inside of the two-P, sucks air from the annular gap, crosses the inside of the water remover, and sends a descending airflow toward the center opening of the tray; (f) a wall formed around the periphery of the tray, rising up towards the fan and guiding the fan-blown air flowing across the underside of the water removal chamber towards the annular gap through the opening; and another wall that guides the air rising from the tray and entering the annular gap upwards towards the underside of the tray V. (h) a chamber for dispersing the liquid carried over the peripheral wall; and (h) a passageway for the sucked air to cross the peripheral tray wall, cross the inside of the water remover, enter the fan, and flow. It has a miscellaneous equipment and a.

This water remover does not involve direct contact between the sponge or other liquid collection means and the ground. Instead, the liquid is forced toward the annular gap by the fan-blown air, enters the water remover, and the air circulates through the water remover toward the fan.

sucked into the gap. The water remover operates very efficiently, and there is almost no tradel.

In the preferred embodiment described herein, the descending airflow generated by the fan is such that the air blown through the tray opening and across the underside of the dewatering machine, when the dehydrator is in use, It constitutes the main means or only means for supporting the lower side of the water remover above the ground. In other words, the water remover functions as a hovercraft. These water removers do not run on wheels on the ground and can use the same fan and moving crab unit to form both the air cushion supporting the water remover and the air suction that lifts the liquid.

Preferably, the liquid carried over the peripheral walls of the tray is
It moves straight across the inside of the water remover and is carefully prevented from reaching the rotating fan.

ing. This will prevent the fan blades from getting wet or rusty. If a small amount of liquid is circulated by the fan, the effectiveness will be less than optimal, but the dehydrator will still have the maximum liquid removal capacity.

Such dehydrators, which prevent liquid from reaching the fan, can also be constructed from baffles. The baffle forcefully deflects the liquid into the liquid receiving chamber as it leaves the top of the surrounding tray wall. Appropriate baffles may be incorporated while leaving a path for suction air from the top of the peripheral tray wall across the interior of the water extractor to the fan.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

This water remover is basically circular in plan view.

When viewed from the side as shown in FIG. 1, it has a substantially convexly recessed hood indicated by 11. A flat tray 12 is provided inside the hood.

The hood 11 forms the upper and side parts of the water remover, and
A flat tray 12 forms the underside of the water remover.

An annular gap 13 extends around the entire circumference of the water remover, and the hood 1
It is intentionally provided between the periphery of the tray 10 and the periphery of the tray 120.

A fan 14 is mounted centrally and inside the hood 11. A motor 15 is attached to the outside of the hood and drives the fan 14.

A central circular opening 16 is formed in the tray 12 directly below the fan. Also, a cylindrical wall 17 is formed around the opening 16,
It rises up to the fan and forms a duct for the descending air flow that occurs when the fan is used.

Another cylindrical wall 18 rises from the periphery of the tray towards the underside of tool P11, but does not reach the underside of the hood. The walls 17, 18 together with the tray 12 form an annular chamber inside the dehydrator.

When the fan 14 rotates, the direction shown by the arrow in FIG.
That is, the fan blows the descending air in the direction of the opening 16, across the underside of the tray 12, and toward the annular gap 13. A passage is effectively formed in the gap 13 over the tray wall 18 and across the underside of the door 11 to the fan 14, so that the fan 14 draws air into the annular gap and fills the same volume. Air is effectively circulated through a water remover.

A unique feature of this water remover is that the downdraft generated by the fan has sufficient force to lift the water remover off the ground. Thus, when the water remover moves over a layer of liquid spread on the ground, the downdraft blows the liquid towards the annular gap 13 and the liquid is then sucked into the water remover. Most or all liquids are removed from the air hood 11.
As it moves across the underside of the fan 14 into the fan 14, the portion 12
．． It naturally accumulates in the chamber formed by 17 and 18.

Air is being sucked into the annular gap 13 not only from the fan but also from the area around the water remover just outside. In this way, the same motor-driven fan creates both the air cushion upon which the water remover moves and the suction airflow that draws liquid spread on the ground into the water remover.

As FIG. 2 shows, the motor 15 is controlled by a lever 19. As shown in FIG. This lever is similar to the conventional cable machine 41
1 is connected to the motor's casole. The motor in this special case is 8 horsepower (Br1gg5h5tra
It is an air-cooled 4-stroke 320CC single-cylinder gasoline engine manufactured by Tton. This engine drives the fan 14 through suitable bearings and couplings, but does not use any reduction gears in the drive process. The handle 21 swings about a horizontal axis 22 to easily direct the dehydrator to the desired arc or linear travel. The nondle 21 is hinged about another horizontal axis so that it can be folded onto the handle itself to reduce its size as much as possible for loading or transport without the use of a dehydrator.

As shown in FIG. 6, the upper surface of the hood 11 is divided into seven fan-shaped sections. Each of these sectors can be removed to gain access to the interior of the water extractor. In FIG. 6, two sectors have been removed. The design of the seven fans is due to the commercially practical size of the dehydrator; the resulting fan panel is not too large to remove, but too small to create the curvature of the dehydrator hood. do not have.

A partition wall 24 radiates out from the center of the hood.

Arched passages 25 are cut out of these partitions, and the chambers formed between the tray 12 and the tray walls 17 and 18 are continuous around the inside of the water extractor. As shown, the top panel of the hood 11 is raised approximately 15 degrees from the horizontal when the water remover is in its normal position. The panel shows that the air moving away from the top of the tray 18 causes a pressure drop and therefore removes the liquid that was being carried into the water remover.
In order to obtain the desired effect, such as losing the "supporting force",
It is raised at an angle of 10 to 25 degrees with respect to the horizontal plane.

A baffle plate 26 spans the continuous bulkhead 24 around the water remover. As the liquid is sucked over the top of the peripheral tray wall 18, it impinges on the baffle and is forced to be deflected into the liquid receiving chamber. However, as FIG. 4 shows, a passageway is provided for air to cross the bottom of the dehydrator and return to the fan.

FIG. 5 shows in detail the blades P of the fan 14. This unique fan is a seven-bladed fan, and the angle of attack of each blade can be varied. Preferably, in the water remover shown, the attack angle is about 35 degrees relative to the horizontal plane. This angle can also vary between 55 degrees and 4D degrees, depending on the exact conditions under which a given dehydrator is used. The standard water remover shown used a Hirosaku grain dryer fan.

The particular water remover shown has a diameter of approximately 4 feet (122 centimeters), measured at the outer edge of the annular gap 13. The gap itself is approximately 0.75 17chi (1,
9cm) width.

It is constant around the water remover. The distance between tray walls 18 and 17 is approximately 8° 25 inches (21 centimeters) and fan 14 is 19 inches (48 centimeters).
It has a diameter of

The tips of the fan blades are approximately 5.5 inches (14 centimeters) from the floor of the liquid storage chamber formed by tray 12.
The perimeter of the upper section of the upper section is approximately 9 inches (25 centimeters) above the tray 12, while the top of the central hood, attached to the motor 15, is above the floor of the tray 12. It is located approximately 12 inches (50 centimeters) above.

A cap K is attached to the drain port 27 as shown in FIGS. 5 and 4. When the character is set to 7°, all the water actually comes out from the internal chamber of the water remover.

Alternatively, the water can also be pumped out via a suitable hose. Water can also be constantly pumped out as the machine moves over flooded areas. Alternatively, if the liquid storage chamber of the water remover is very large, it can also be pumped out at intervals.

In FIG. 6, the exhaust gas from the air-cooled gasoline engine 15 is sent directly below the fan 14 in the water remover before being discharged to the atmosphere. The exhaust gas becomes hot during use and fan 1
The downdraft from 4 is heated and serves to evaporate the fluid below the dehydrator. This increases the efficiency of the water remover.

Also shown in FIG. 6 is an iris or camera shutter type vent 28 provided in one of the upper panels of the hood 11 and connected by a cable mechanism to a lever (not shown) on the handle 21. The vent normally remains closed. Water remover across the area where there is no need to suck into the fractured gap? You can open the vents whenever you want to move. For example, a water remover may cross a gravel walkway that divides a flooded viewing area. Under these circumstances, the dehydrator must remain afloat, but must not suck gravel into the liquid containment chamber. In such a case, the vent 28 is opened and then closed again when the dehydrator is used in liquid suction mode.

77n14 can also be used in modes other than the drainage mode mentioned above.
Since air is taken in from the annular gap 13, there is almost no horizontal dissipation of air around the water remover.
It has two advantages. First, the liquid covered by the moving water remover is not sprayed onto the water remover operator or nearby spectators.

Secondly, using something in the form of a flexible skirt to create an air cushion on which the water remover floats? There is no need to go. Such skirts are notoriously susceptible to tearing when used in the most common hovercraft configurations.

In FIG. 7, the primary means of supporting the dehydrator is a pair of flotation wheels on a treadless low pressure balloon tie. The water remover operates in the manner described above, but it does not float. The wheels can be made removable so that the operator can use the water remover in floating or non-floating mode depending on the situation.
