FIG. 1 is a diagram showing a water tank in which a tank is immersed and mud is washed away. Example 1 FIG. 2 is a view showing a spray device that sprays spray from around the tank. (Example 2) FIG. 3 is a view showing a device which is attached near the caterpillar and sprays the caterpillar directly. (Example 3)

  In the present invention, a cleaning system and a cleaning method for a tank, particularly a cleaning system and a cleaning method for an entire tank and a caterpillar of a tank are provided.

  According to the present invention, first, a tank to which mud or the like is attached during training or the like enters the aquarium 1 having a depth that allows at least a part of the wheels to be immersed. At least a part of the wheel may be immersed in water, but in order to wash more efficiently, it is preferable that almost the entire lower wheel is immersed in water. Here, when the wheel is immersed in water, a certain part such as mud adhering to the wheel or the caterpillar falls to the bottom of the water. At this time, the length of the water tank is preferably such that the caterpillar can rotate at least once. If it is shorter than one rotation, some of the caterpillars remain on the ground, or a portion that is not immersed in water is generated, and mud or the like in that portion is difficult to fall off. Also, since the slope is necessary so that the tank can enter the aquarium smoothly, that part is also necessary.

  At this time, in order to more efficiently remove deposits such as mud, deposits such as caterpillars and wheels can be washed away more efficiently by generating a water flow with a pump or the like. The mode of water flow may be jet water flow or spiral water flow and is not particularly limited. Further, it may be a continuous water stream, an intermittent water stream, or a water stream containing air.

The water flow is caused by jetting water from a water flow nozzle. This water is pumped up by the submersible pump of the water tank 1 and is jetted from the water flow generation nozzle 14 via the valve 16 to generate a water flow.
A water level meter is provided in the water storage tank. When the water level drops below a predetermined water level, the valve 15 extending from the water tank 1 to the sand separator is opened to feed water. When the water level in the water storage tank 6 is equal to or higher than a predetermined level, the valve 15 is closed, the valve 16 is opened, and water is fed toward the water flow generating nozzle to generate a water flow. The valves 15 and 16 are preferably electromagnetic valves, but may be manually operated.

  In addition, before the tank enters the tank 1, by installing a device for cleaning the caterpillar of the tank in the mudguard portion of the tank and spraying mud etc. adhering to the caterpillar as the caterpillar rotates Can be washed. As a device for cleaning the caterpillar, a high-pressure water injection device is preferably used. This is because mud or the like may be pressure-bonded to the caterpillar at a high pressure, and it may be difficult to remove with a normal pressure. High pressure in this case refers to 50-200 atmospheres. More preferably, it is 80-120 atmospheres.

In order to enhance the cleaning effect of the caterpillar, air may be mixed into the high-pressure water. In order to mix air, an ejector capable of adjusting the amount of mixed air with a screw or the like is preferably used.
The water in the aquarium 1 is in a state where mud and the like are suspended by the passage of the tank. The suspended water from the mud and the like is sent to the sand separator 5 by the intake pump 4 and is centrifuged to form particles such as mud and sand. Is separated and becomes a supernatant water with less mud after treatment. This supernatant water is stored in the water storage tank 6 and reused as cleaning water for the caterpillar and water for spraying in the next spray section.

At this time, the clarity of the reused water can be increased by inserting a filter between the sand separator 5 and the water storage tank 6. Examples of the filter include a mesh filter (for example, 150 mesh), a disk filter, and the like.
The reused water stored in the water storage tank 6 is sent to the spray section by the high-pressure pump 8 as necessary.
FIG. 2 shows the spray cleaning apparatus from the top, side (side), and bottom after washing mud in the water tank of FIG. Tanks that exit the aquarium travel between pipes with spray nozzles around them. During this time, mud and the like are further washed away by spray from the surroundings.

  At this time, pipes with spray nozzles should be installed not only on both sides, but also on the upper side of the tank and on the lower side of the bottom, and spray water on the top, bottom, and inside of the caterpillar for cleaning. Can do. At this time, by using a rotating nozzle at the bottom, water can be sprayed not only on the bottom surface of the tank, but also on the inside of the caterpillar and the wheel, and the cleaning effect can be further enhanced.

  At least two apparatuses for cleaning the upper part, the side part, and the lower part are used, and for the first cleaning that comes out of the water tank 1, reused water obtained by treating the water in the water tank in FIG. In the cleaning device, cleaning is performed using clear water such as well water and tap water, so that mud adhesion can be minimized while saving the use of water.

FIG. 3 shows an apparatus installed near the caterpillar to flush mud and the like that has entered the caterpillar by spraying high-pressure water directly on the caterpillar.
In this case, the pipe with the spray nozzle may be installed anywhere as long as the high pressure water can be directly sprayed onto the caterpillar, but can be suitably installed in the mudguard portion of the tank. By installing a nozzle at an angle that allows high-pressure water to be injected at an angle that is nearly perpendicular to the caterpillar's surface in the tank mudguard part, and perpendicular to the surface of the caterpillar, Particles such as fine mud that enter between the caterpillars can be washed away. In this case, as described above, the cleaning effect can be enhanced by mixing air.

The water for spraying used here is also reused the water in the water tank of FIG.
In the cleaning process of the spray from the top of the caterpillar in FIG. 3, the caterpillar needs to make a round under the spray nozzle in order to clean the entire circumference of the caterpillar, so it is necessary to move at least twice the total length of the tank. . By reciprocating back and forth in the water tank 1, this requirement is satisfied. In this case, if the spray nozzle can be installed also in the mudguard part at the rear of the tank, the entire circumference of the caterpillar can be cleaned by only a half circumference.

  In addition, since washing wastewater comes out after washing | cleaning with a spray part, it is necessary to process this washing wastewater appropriately. It is preferable to reuse after processing with a sand separator and a filter as in FIG.

  In FIG. 1, tanks are almost immersed in tanks 1, and water is stretched to such an extent that water does not enter the engine section. When a tank enters this water tank 1 and the caterpillar advances at least as much as possible, mud adhering to the caterpillar and wheels can be washed away to some extent. In order to wash off mud more efficiently, more mud can be washed out by reciprocating the distance that the caterpillar can make one round in the water tank 1 several times. In order to sufficiently remove mud, it is preferable to reciprocate three or more times.

The water in the water tank 1 is preferably well water if there is a well, but it may be tap water or river or pond water if it is clear, and is not particularly limited.
Moreover, the means which raise | generates water flows, such as a pump, in the said water tank 1 can be installed, and the efficiency which washs off mud etc. can be raised by raising a water flow after a tank enters. For example, the cleaning efficiency can be further increased by generating a water flow so as to hit a caterpillar or a wheel. This water flow can be generated by jetting water pumped up from the water tank 1 by a submersible pump from a water flow generating nozzle.

  Since the water in the aquarium contains a large amount of fine mud particles and the like, if it is discharged as it is, it will flow into the field and may cause adverse effects on the crops in the field due to poor drainage. Therefore, the water in the water tank 1 is pumped up by the water intake pump 4 and sent to the sand separator 5. Particles such as mud and water are separated by centrifugation at the sand separator 5, and the supernatant water with less mud is sent to a water storage tank 6 for water for spraying and stored. The water in the water storage tank 6 is sent to the spray section of the second and third embodiments by a high-pressure pump 8 through a pipe or a hose and reused as spray water.

Particles such as mud accumulated in the sand separator 5 can be appropriately removed automatically or manually.
At this time, a more purified spray water can be obtained by inserting a suitable filter between the sand separator 5 and the water storage tank 6.

  FIG. 2 shows a spray that flushes away dirt from wheels and caterpillar by spraying around the tank. The water stored in the water reuse tank 6 for spraying that came out in the first embodiment is guided to the spray section by a pipe (hose), and is pressurized by the high-pressure pump 8 so that both sides, upper and lower sides of the tank. Sprayed from the spray nozzle. In this case, not only the outer side of the caterpillar but also mud adhering to the upper part of the tank, mud adhering to the lower part, and mud adhering to the inner side of the caterpillar can be removed by washing. This spray section is provided at two locations, and the mud can be removed more effectively by washing with reused water at the beginning and washing with clear water such as well water and tap water at the second time. .

  The distance between the spray nozzles on both sides and the tank depends on the size of the tank, but is preferably between 50 cm and 100 cm. If it is too close, it may come into contact with the tank. If it is too far, the spray pressure will be weak.

  FIG. 3 shows a device that sprays high pressure water on the caterpillar from a short distance by installing a high pressure water spray just above the caterpillar, and removes mud and the like adhering to the caterpillar. The installation site of the pipe having the spray nozzle is not particularly limited as long as it is a site where high-pressure water can be sprayed onto the caterpillar, but it is preferably installed below the mudguard portion of the tank. As a method for fixing the spray nozzle, a clip, a magnet (electromagnet), and the like are conceivable, but there is no particular limitation as long as the structure can withstand high pressure during cleaning.

Moreover, although this washing | cleaning can also be performed separately after a side spray finishes etc., it is preferable to carry out simultaneously while reciprocating the water tank 1 of FIG.
Alternatively, it can be performed simultaneously with the side spraying of FIG. That is, when passing through the side spray area of FIG. 2, the pipe having the high pressure water spray nozzle of FIG. 3 is installed under the mudguard portion of the tank and the high pressure water is sprayed on the caterpillar. The mud etc. that has entered is pushed out and can be washed away by spraying from the side (and bottom).

By performing the cleaning of the caterpillar simultaneously with other cleaning steps, the area required for cleaning can be reduced, and the cleaning time can be shortened.
In this case, in Example 2, since the distance for one rotation of the caterpillar is required, a long hose for supplying high-pressure water is required. If it does not make one rotation, a caterpillar part that remains on the ground is generated, and the cleaning of that part becomes insufficient.

  Since the wastewater washed in Examples 2 and 3 also contains fine mud, wastewater treatment is also necessary for these washing wastewaters. Therefore, it is preferable that the waste water discharged from here is also reused as spray water after being treated with a sand separator and a filter.

  According to the present invention, it is possible to shorten the cleaning time after tank training and to reduce cleaning wastewater, so that it can be used in military-related industries and environment-related industries. Moreover, since this system can be applied to heavy machinery and vehicles having a caterpillar, it can be used in the civil engineering and construction industries.
