Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cleaning device with a cleaning liquid regenerating device.

Conventional technology Printed parts, electronic parts, etc. are immersed in a cleaning tank to remove unnecessary deposits and dust, but with conventional cleaning equipment, if the cleaning liquid in the cleaning tank becomes dirty, the dirty This was done by draining the cleaning fluid and supplying new cleaning fluid.

However, in order to better clean the parts, it is necessary to frequently supply new clean cleaning liquid to the cleaning tank and drain dirty cleaning liquid, which is time consuming and increases costs.

Means for Solving the Problems The present invention was developed in view of the above-mentioned problems, and in order to solve the above-mentioned problems, it is a cleaning device that cleans objects to be cleaned, such as printed parts and electronic parts, with a cleaning liquid. In a cleaning device equipped with a cleaning liquid regenerating device in which a regenerating device is installed in parallel so that dirty cleaning liquid can be freely recycled and recovered, a nozzle pipe for injecting the cleaning liquid into the cleaning device is arranged so as to be swingable at a predetermined angle. A feed pump is connected to the supply pipe to which this nozzle pipe is connected, so that the cleaning liquid can be freely fed to the cleaning device and the regeneration device, respectively, and a cylindrical heat pipe is used as the evaporation device of the regeneration device. It is an object of the present invention to provide a cleaning device with a cleaning liquid regenerating device, characterized in that it has a double cylindrical inner wall structure.

Function According to the present invention, cleaning liquid can be sprayed from the nozzle pipe onto the object to be cleaned by swinging the nozzle pipe, and dirty cleaning liquid can be regenerated and recovered by a regeneration device installed in parallel, so that the cleaning liquid is always clean. It can be cleaned with a clean cleaning liquid, which saves cleaning liquid, and also eliminates the need for frequent handling such as supplying new cleaning liquid and discharging dirty cleaning liquid. When the cleaning liquid in the cleaning device becomes dirty, the cleaning liquid is sent to a parallel regenerating device for regeneration and recovery, and the cleanly regenerated cleaning liquid can be used to clean the object to be cleaned. Therefore, although the cleaning solution can be cleaned at all times, the amount of cleaning solution can be saved, and the trouble of supplying new cleaning solution and frequently discharging dirty cleaning solution can be saved.

In addition, since the evaporation device of the regenerator has a cylindrical heat pipe structure and evaporates through the double cylindrical inner wall, even if the cleaning liquid is a flammable organic solvent such as thinner, This is preferable because it can be heated indirectly through a heat pipe structure and can be safely regenerated.

Example The present invention will be explained below based on examples.

FIGS. 1 and 2 show an embodiment of the present invention.
The cleaning device 1 is mounted on a support frame 4 disposed at a predetermined height of a cart 3 with wheels 2 attached thereto, as shown in FIGS. A tank 5 is installed, and a cleaning liquid regenerating device 6 such as thinner is installed on the side. The cleaning device 1 is formed in the shape of a rectangular parallelepiped box as shown in FIGS. 1 and 2, and an opening/closing lid 7 is pivotally connected to the front side of the box in a watertight manner so that it can be opened and closed, and is used to store printed parts, electronic parts, etc. A cleaning basket 9 containing objects 8 to be cleaned can be inserted into and removed from a housing section 10 attached to the inside of the opening/closing lid 7, so that cleaning can be carried out by replacing the items as needed. Further, inside the cleaning device 1, nozzle pipes 12 and 13 having nozzles 11 attached at regular intervals around the circumference are installed horizontally in the upper and side parts of the cleaning basket 9 as shown in the figure. , a supply pipe 15 connected to the discharge side of the supply pump 14 connected to the lower cleaning liquid tank 5;
6 to the nozzle pipes 12 and 13, so that the object to be cleaned 8 can be cleaned by spraying cleaning liquid from above and from the sides. A rocking device 17 such as a rotary actuator attached to the side circumference of the cleaning device 1 is connected to one end of the nozzle pipe 13 installed on the side, as shown in FIG. The nozzle 11 is rotated as shown in Fig. 2.
can be rotated up and down at a predetermined angle to enable injection. The rocking speed may be a constant speed or may be a combination of appropriate speeds such as high, medium and low. 18 is an operation panel, 19 is an opening/closing chain, 2
0 is an opening/closing handle, 21 is a filter, 22 is a tank inflow pipe, and 23 is a tank replenishment pipe.

On the other hand, the regenerating device 6 is formed of an evaporator 24, a condensing device 25, etc., and as shown in FIG. is installed. The evaporator 24 has an upper lid 26 attached to the upper part so as to be openable and closable, a double cylindrical inner wall 27 with a cylindrical heat pipe structure inside, and an insulating flexible tube with a supply pipe 15 branched and connected. The cleaning liquid 11 loaded onto the inner wall 27 of the evaporator 24 through the regeneration pipe 28 can be heated and evaporated via the inner wall 27 having a heat pipe structure with a heating device (not shown) attached to the lower part of the inner wall 27. That's what I do. The evaporated cleaning liquid flows to the adjacent condensing device 25,
As shown in the figure, the cleaning liquid can be collected into the cleaning liquid tank 5 via a collection pipe 29. 30 is a regeneration on-off valve.

Therefore, if a predetermined object to be cleaned 8 is stored in the cleaning basket 9 and attached to the storage part 10 of the opening/closing lid 7 of the cleaning device 1, the opening/closing valve 16 is opened and a prescribed switch on the operation panel 18 is turned on. The feed pump 14 is driven to feed the cleaning liquid to the nozzle pipes 12 and 13, and the cleaning liquid is sprayed vertically and horizontally from the nozzle 11 at the tip toward the object 8 to be cleaned. At this time, the nozzle pipe 13 on the side face is rotated up and down by the swinging device 17 and sprays the cleaning liquid onto the object 8 to be cleaned, thereby uniformly cleaning the object 8 in the cleaning basket 9. can. After cleaning for a predetermined period of time, the lid 7 is opened and the next object 8 to be cleaned is placed in the same manner and cleaned.

If the cleaning liquid becomes dirty in this way, the on-off valve 16 is closed, the regeneration on-off valve 30 is opened, and the cleaning liquid is loaded into the evaporator 24 of the regeneration device 6. and,
When the evaporator 24 is heated, the cleaning liquid evaporates and flows out, is condensed in the condenser 25 on the side, and can be collected in the cleaning liquid tank 5. Therefore, the recycled and recovered cleaning liquid can always be used to clean cleanly as described above. Note that the cleaning liquid can be replenished via the tank replenishment pipe 23 at appropriate cycles.

In particular, the evaporation device of the regenerator has a cylindrical heat pipe structure and evaporates through the double cylindrical inner wall, so even if the cleaning liquid is a flammable organic solvent such as thinner, it can be regenerated safely. It is possible and desirable. In this case, if an electromagnetic induction heating device is used as the heating device for heating the inner wall, it is safer and more preferable because heating can be performed without using a fire.

Other Embodiments In the above embodiments, one cleaning liquid tank was used, but it is possible to install multiple cleaning liquid tanks and regenerate the cleaning liquid in other cleaning liquid tanks while cleaning one cleaning liquid tank. It is also possible to install a liquid tank so that cleaning and rinsing can be performed sequentially.

In addition, in the above embodiment, an opening/closing lid was provided on the side so that the items to be cleaned could be taken in and out, but it was also possible to arrange a conveyor in the cleaning device to process the items to be cleaned in batches or continuously. It is also possible to automate cleaning and recovery by using the on-off valve and regeneration on-off valve as an automatic on-off valve.

Although we have described the organic solvent of thinner as the cleaning liquid, it can be applied similarly to other required organic solvents, and can also be applied to ultrasonic cleaning using an immersion type instead of a jet type cleaning. It is something.

Effects of the invention As described above, in the present invention, the cleaning liquid can be sprayed from the nozzle pipe onto the object to be cleaned by shaking the nozzle pipe, and the cleaning device can clean the object to be cleaned. can be regenerated and recovered using a regeneration device installed in parallel, allowing cleaning with clean cleaning fluid at all times, saving cleaning fluid, and eliminating the hassle of handling, such as supplying new cleaning fluid and frequently discharging dirty cleaning fluid. can be omitted.

In addition, since the evaporation device of the regenerator has a cylindrical heat pipe structure and evaporates through the double cylindrical inner wall, even if the cleaning liquid is a flammable organic solvent such as thinner, it can be used indirectly. This is preferable because it can be heated to a high temperature and can be safely regenerated.
