Description

  TECHNICAL FIELD The present invention relates to a wet cutting powder separating apparatus capable of separating and removing cutting powder that has become wet due to rainfall or the like during working such as forming joints with a dry cutter.

  Dry joints and grooves are formed on concrete and asphalt pavements without using cooling water, and the blades of the dry cutter are housed in a cover and surrounded so that cutting powder does not scatter. There is known a dry cutter that sucks cutting powder that has risen into the cover by cutting and sucks the cutting powder and collects it with a filter.

In order to improve the drainage of the road surface and prevent a slip accident, a plurality of grooves are formed on the surface of the paved road, and a dry grooving method is performed in which the grooves are cut dry.
FIG. 4 shows a grooving apparatus used in a dry grooving method, in which a plurality of blades are arranged in parallel and these blades are covered by a blade cover. Air is blown from the compressor to the blade, and air in the blade cover is sucked together with cutting powder by a suction device. The suctioned air containing the cutting powder is removed by the filter, and the air not containing the cutting powder is discharged from the suction device.

If there is rain when performing groove cutting on the road surface, the road surface becomes wet, and the rainwater flowing on the road surface is absorbed by the cutting powder, and the cutting powder becomes wet with water, separating the cutting powder. The filter to be accommodated is clogged, making it impossible to separate and collect the cutting powder, and the work must be interrupted.
Therefore, in the dry grooving method, if there is rain during the work, the work must be stopped, and the work cannot be started until the road surface dries even after raining, thus reducing work efficiency. It was a factor that would increase costs.

  Even if the cutting powder contains moisture due to rain or the like, the present invention separates and collects only the cutting powder in the wet state so that it does not turn to the separation filter, and passes only the dry cutting powder to the filter. An apparatus for separating and collecting wet cutting powder to be sent is provided.

  A cylindrical wet cutting powder recovery container and a cyclone separator detachably provided on the upper side of the recovery container. A circle of a recovery container that sucks and collects cutting powder from the cutter blade cover on the upper side of the cyclone separator. A circumferential suction port is provided, and a detachable lid is provided on the upper part of the cyclone separating device, and the dry cutting powder after the wet cutting powder is separated by the cyclone is sent to the lid to the filter. This is a wet cutting powder separating device for a dry cutter in which a discharge port is formed.

When there is rainfall during work such as dry grooving, the cutting powder on the paved road surface cut by the blade is sucked into the wet state by the rain and sucked into the wet cutting powder separator installed in front of the filter. Sent by. The wet cutting powder is introduced into a cyclone separation device of the wet powder separation device, and the cutting powder that has absorbed water and has increased in weight falls down the cyclone separation device and is collected in a collection container.
The dry cutting powder that does not contain moisture floats in the center of the cyclone separator while the wet cutting powder descends in the cyclone separator. Since a suction flow toward the filter is generated in the center, the suction flow flows toward the filter from the discharge port provided in the lid of the dry cutting powder cyclone separator and moves toward the filter.

Since the dry cutting powder sent to the filter does not contain moisture, the filter is not clogged.
As described above, even if it rains, the wet cutting powder is sent to the collection container by the cyclone separator and separated from the dry cutting powder, so that cutting work such as grooving can be continued and construction efficiency is improved. be able to.
Further, since the wet cutting powder is collected in the collection container, the cutting powder in the collection container is easily packed in a collection bag or container by removing the cyclone separation device that is detachably attached to the upper part of the collection container. Therefore, the cutting powder can be disposed of efficiently.

The conceptual diagram of the separation apparatus of wet cutting powder. The perspective view of the separation apparatus of wet cutting powder. The schematic which attached the separation device of wet cutting powder to the dry type grooving device. Schematic of a dry grooving apparatus.

  As shown in FIG. 1, the collection container 2 of the wet cutting powder separating apparatus 1 has a bottom plate 20 and has a cylindrical shape made of resin or metal. A cylindrical cyclone separator 3 having the same diameter as the recovery container 2 is installed in close contact with the recovery container 2 via a seal 34, and is fixed and integrated by a fastening tool 21 such as a buckle provided on a side surface. ing.

A detachable upper lid 30 is fixed to the upper part of the cyclone separator 3, and a discharge port 31 is provided at the center of the upper lid 30. The upper lid 30 is fixed via a seal, and the sealing performance is maintained. A hose 4 is connected to the discharge port 31 and is connected to a filter 5 that collects cutting powder generated by the dry cutter 10 and prevents dust from being scattered around. In addition, a discharge pipe 32 protruding from the discharge port 31 to the inside of the cyclone separator 3 is provided. The discharge pipe 32 sucks the cutting powder floating without being separated by the cyclone separator 3 to filter 5. To send to. The discharge pipe 32 is surrounded by a cylindrical shielding wall 33 so that wet cutting powder is not sucked into the discharge pipe 32. The discharge pipe extends below the lower end of the shielding wall 33 and has a length that enters the collection container 2 by about 20 mm.
The suction flow toward the filter 5 is caused by the suction force of the suction fan 50, and the dry cutting powder sucked from the wet cutting powder separation device 1 is removed by the filter 5, and the cleaned air is sucked into the suction fan 50. Discharged from.

  A suction port 35 is formed on the side surface of the cyclone separator 3, and the discharge port 12 of the blade cover 11 that houses the dry cutter 10 is connected to the suction port 35 via a hose or the like. When the dry cutter 10 is operated, compressed air is sent from a compressor (not shown) into the blade cover 11 to cool the cutter, and the cutting powder is easily sucked into the cyclone separator 3 side.

The cutting powder generated when the dry cutter 10 cuts the road surface is sucked by the suction flow by the suction fan 50 provided in the filter 5. Further, the cutting powder is lifted and sucked by the cooling compressed air flow sent into the blade cover 11 and enters the inside of the cyclone separator 3 through the suction port of the cyclone separator 3. The cutting powder containing heavier moisture while swirling inside swirls around the outermost periphery, collides with the peripheral wall of the cyclone separator 3, loses kinetic energy and falls into the recovery container 2 provided below. Go.
Light dry cutting powder that does not contain moisture floats in the airflow swirling around the center of the cyclone separator 3 and swirls in a spiral shape. In the upper part of the cyclone separator 3, a suction airflow from the discharge port 31 toward the filter 5 is generated, so that the dry cutting powder is sucked from the suction pipe 32, carried to the filter 5 and collected.

  Since the cutting powder sucked into the filter 5 is only dry cutting powder that does not contain moisture, the dry cutting powder that has reached the filter 5 can be continuously operated without clogging the filter 5. is there.

  The wet cutting powder that clogs the filter 5 is completely removed by the cyclone separator 3, and only the dry cutting powder is sent to the filter 5, so even if there is rainfall during the cutting operation, the operation is immediately stopped. Therefore, it is possible to continue the cutting work without any trouble and to eliminate the work waiting time due to the rain, so that the work efficiency can be improved.

FIG. 3 shows a state in which the wet cutting powder separating device of the present invention is mounted on the conventional dry grooving device shown in FIG. 4 as an adapter.
The wet cutting powder separating device is fixed to a vacant portion of a box that accommodates a filter of the dry grooving device by an appropriate means.
By attaching the wet cutting powder separating device 1, the blade cover discharge port 12 is connected directly to the filter 5 by the connecting hose to the suction port 35 of the wet cutting powder separating device 1, thereby separating the wet powder. The discharge pipe 32 of the apparatus is connected to the filter 5 by the hose 4. The filter 5 is connected to the suction device 50 as in the conventional device.
Since the wet powder separator is attached to the dry grooving device as an adapter, the connection between the wet cutting powder separator 1 and the filter 5 is released in the conventional connection form when the clear sky is expected to continue. The cover outlet and the filter may be connected directly, and the connection may be changed when it starts to rain.
In addition, by providing a bypass in the connecting path between the blade cover 11 and the filter via a switching valve and connecting the wet powder separator to this bypass, the function of the wet powder separator can be turned on and off by the switching valve. .
