Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cleaning device, and more specifically, to a drying unit capable of drying cleaning fluid adhering to the surface of an object to be cleaned. The present invention relates to an integrally provided cleaning device.

[Conventional technology]

As is well known, it is common practice to use cleaning fluids to clean objects to be cleaned. When the cleaning process is performed using the cleaning fluid in this manner, the cleaning fluid remains attached to the surface of the object to be cleaned.
In order to dry the cleaning fluid that adheres and remains, a drying section is provided next to the cleaning tank, and a conveyor transports the cleaning object that has been cleaned in the cleaning tank through the drying section, where it is dried. A cleaning device designed to do this has been put into practical use.

Conventionally, the drying means used in such a cleaning apparatus is a drying means that blows hot air heated by an appropriate heating means onto the surface of the object to be cleaned.

[Problem that the invention attempts to solve]

By the way, the cleaning fluid that adheres to the surface of the object to be cleaned may be in the form of a thin film or in the form of beads. The inner beads described above tend to adhere and remain between the object to be cleaned and the conveyor.

When drying the surface of an object to be cleaned by blowing hot air onto it, the cleaning fluid attached to the surface of the object in a thin film can be dried in a relatively short period of time. However, since the cleaning fluid adhering in beads cannot be evaporated immediately, a long time and a large amount of heating are required to dry it.

Therefore a. Since the passage path for the object to be cleaned must be long, the drying section must be made large. Also b. The drying temperature must be increased, which requires larger drying equipment and increases running costs. Furthermore c. Because the drying time is different for the cleaning fluid that adheres in a thin film and the cleaning fluid that adheres in the form of beads, uniform drying cannot be performed and stains may appear on the surface of the object to be cleaned. Sometimes it happens.

This invention was created in view of the above points,
The purpose of this is to create a cleaning device that requires less heat for drying, can dry the entire surface of the object to be cleaned almost uniformly, and is particularly compact in its overall size. It is on offer.

[Means for solving problems]

The present invention has the following technical means to achieve the above object. That is, to explain using the reference numerals used in the attached drawings corresponding to the embodiments, the cleaning object 3
a washing section 4 for washing the object 3, a drying section 5 for drying the object 3 to be washed, and a washing device 1 for drying the object 3 to be washed.
between the cleaning section 4 and the drying section 5, the object to be cleaned 3, and the object to be cleaned 3 and the conveyor 6, This cleaning device is equipped with a suction drying section 20 that can suction and remove the cleaning fluid 2 that is present in the cleaning fluid 2 using negative pressure.

[Effect]

The object to be cleaned 3 is placed on the conveyor 6 and is transferred from the inlet 7 side to the outlet 8 side of the cleaning device 1. While being transferred in this way, the object to be cleaned 3 is first transferred to the cleaning section 4. Washed. The cleaning fluid 2 used for cleaning may adhere to the surface of the cleaning object 3 that has been cleaned or between the cleaning object 3 and the conveyor 6 in the form of beads. This beaded cleaning fluid 2 is suctioned and removed by negative pressure in a suction drying section 20 provided next to the cleaning section 4. As a result, the cleaning target 3 and the cleaning target 3
The cleaning fluid 2 is only slightly attached in a thin film between the cleaning fluid 2 and the transport conveyor 6. In the drying section 5 provided in the next stage, hot air is blown onto the surface of the object to be cleaned 3 to dry it, thereby completely drying the cleaning fluid 2 adhering to the surface of the object to be cleaned 3. .

〔Example〕

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, 1 indicates a cleaning device, which includes a cleaning section 4 that cleans the cleaning object 3 using the cleaning fluid 2, and a cleaning section 4 that dries the cleaning fluid 2 attached to the surface of the cleaning object 3 that has been cleaned in the cleaning section 4. A drying section 5 for processing is provided, and the object to be cleaned 3 is placed on a conveyor 6 and is washed and dried while being transferred inside the cleaning device 1 from the inlet 7 side to the outlet 8 side. It's getting old.

The cleaning section 4 includes a first cleaning tank 9 and a second cleaning tank 1.
0, detergent 2a is provided in the first cleaning tank 9 as cleaning fluid 2, and water 2 is in the second cleaning tank 10.
b is included in each. Inside these first and second cleaning tanks 9 and 10 are ultrasonic transducers 11 and 11.
is arranged to ultrasonically clean the object 3 to be cleaned, which is placed on the conveyor 6 and transferred from the inlet 7 side to the outlet 8 side. The detergent 2a overflowing from the first cleaning tank 9 is
The water is collected in a tank 12 provided below the cleaning tank 9. The detergent 2a collected in the tank 12 is sprayed toward the cleaning object 3 from a spray nozzle 13 disposed above the first cleaning tank 9 by a circulation pump (not shown). .

A similar tank 14 is provided below the second cleaning tank 10, and the water 2b overflowing from the second cleaning tank 10 is collected in the tank 14, and the water 2b is collected in the second cleaning tank 10.
The cleaning target 3 is sprayed from a spray nozzle 15 disposed above the cleaning tank 10 .

The drying section 5 is provided with a drying chamber 16, into which hot air heated by a hot air blower 17 is supplied.

The conveyor 6 is a mesh belt 18 woven from hydrophobic fibers treated with Teflon.
is endlessly wound around the pulleys 19, and one of the pulleys 19 is rotated by a drive motor (not shown) so that the mesh belt surface on which the cleaning object 3 is placed runs from the inlet 7 side to the outlet 8 side. This is what I did.

Next, 20 is a suction drying section provided between the washing section 4 and the drying section 5. The suction drying section 20 is provided to suction and remove the cleaning fluid 2 adhering to the surface of the cleaning object 3 that has been ultrasonically cleaned in the cleaning section 4 or between the cleaning object 3 and the mesh belt 18. It is structured as follows. That is, the suction port 21 is arranged close to the lower side of the mounting surface 18a of the mesh belt on which the object to be cleaned 3 is placed;
The suction port 21 and the vacuum exhaust fan 22 are connected to the exhaust pipe 2.
This configuration is configured by connecting via 3. The evacuation fan 22 can generate negative pressure when driven, and as a result, when the evacuation fan 22 operates, the inside of the exhaust pipe 23 becomes negative pressure.

Next, the operation will be explained based on the above embodiment.

The cleaning object 3 placed on the conveyor 6 at the entrance 7 is transferred inside the cleaning device 1 to the exit 8 side. When the cleaning object 3 is thus transferred to the outlet 8 side, it is first cleaned in the first cleaning tank 9. As described above, this first cleaning tank 9 is an overflow type ultrasonic cleaning tank, and the detergent 2a is used as the cleaning fluid 2. That is, ultrasonic cleaning using the detergent 2a is performed. The cleaning object 3 from which dirt adhering to its surface has been removed by this ultrasonic cleaning is then transferred to the second cleaning tank 10. This second cleaning tank 10 is also an overflow type ultrasonic cleaning tank like the first cleaning tank 9, and here water 2b is used as the cleaning fluid 2. That is,
The detergent 2a used in the first cleaning tank 9 is attached to the surface of the cleaning object 3, but the detergent 2a attached to the surface is washed away by finishing cleaning in the second cleaning tank 10. .

The cleaning object 3 that has been finished cleaned in the second cleaning tank 10 is then transferred to the suction drying section 20.
Water 2b used in the second cleaning tank 10 adheres to the surface of the cleaning object 3 transferred to the suction drying section 20 and between the cleaning object 3 and the mesh belt 18 in beads. A suction port 21 is provided in the suction drying section 20, and air is sucked into the suction port 21 by the negative pressure generated by the evacuation fan 22. The water 2b adhering to the surface of the cleaning object 3 in a bead shape and the water 2b adhering in a bead shape between the cleaning object 3 and the mesh belt 18 are suctioned and removed by the suction force. As a result, at least the water 2b adheres to the surface of the cleaning object 3 and between the cleaning object 3 and the mesh belt 18 in the form of a thin film.

The cleaning object 3 from which the water 2b adhering in the form of beads has been suctioned off in the suction drying section 20 is then transferred into the drying chamber 16 of the drying section 5. Hot air is fed into this drying chamber 16 from a hot air blower 17, and the moisture 2b slightly attached to the surface of the cleaning object 3 in a thin film is dried with hot air and discharged to the outside from the outlet 8 side. To go.

As described above, water 2b adhering to the surface of the cleaning object 3 or between the cleaning object 3 and the mesh belt 18 in the form of beads is removed by the cleaning process using the cleaning fluid 2 in the cleaning section 4. Since the water 2b is removed by suction in the suction drying section 20, when the water 2b enters the drying section 5, almost no water 2b is attached to the surface of the cleaning object 3, or at least it is slightly attached in the form of a thin film. There is only one. When drying the water 2b adhering in a bead shape with hot air, a long time and a large amount of heat are required as described above.

Therefore, in the case of a conventional cleaning device, the hot air drying section 5
The passage path of the cleaning object 3 had to be made long. However, since the water 2b adhering in the form of beads is removed by suction before entering the hot air drying section 5, the hot air drying process can be performed in a short time. Therefore, the length of the hot air drying section 5 can be shortened to 1/3 or less of the conventional length.

Furthermore, as shown in Fig. 3, the water 2b adhering in the form of a bead between the cleaning object 3 and the mesh belt 18 could not be properly dried and removed unless the cleaning object 3 was heated to a temperature close to 100°C. , a large hot air blower was required. However, in the case of this embodiment, since the water 2b adhering in the form of beads is removed by suction in advance and then dried, it is possible to perform good hot air drying using the small hot air blower 17.
Furthermore, the entire circumferential surface of the object 3 to be cleaned can be evenly dried, and problems such as stains can be almost completely eliminated.

In the above embodiment, the cleaning section 4 is shown as an ultrasonic cleaning tank, but it may also be a spray cleaning or stirring type cleaning tank.

[Effect of idea]

As detailed above, in the present invention, the water 2b adhering to the surface of the object to be cleaned 3 or between the object to be cleaned 3 and the mesh belt 18 is removed by suction in the suction drying section 20, and then dried with hot air. Since the amount of heat required for the drying process is small, the hot air drying means can be downsized, running costs can be reduced, and the entire surface of the object 3 to be cleaned can be made almost uniform and even completely. Since the drying process can be performed, stains do not occur on the surface of the object 3 to be cleaned, and there are various advantages such as providing a cleaning apparatus that can be made compact in size as a whole.
