BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a drying apparatus for drying various types of cleaning bodies which have been washed with water and are then dried with hot air after removing moisture from the bodies.

0002

[Prior Art] In general, methods for removing oils and fats and other substances adhering to the surfaces of various processed workpieces by mechanical, chemical, etc. methods, washing with water, and then drying the washed objects include: There are wiping drying methods, centrifugal separation methods, compressed air blowing methods, hot air drying methods, heat drying methods using a drying oven, vacuum drying methods, etc., and each of these methods dry the cleaned body directly or by storing it in a predetermined container.

0003

[Problems to be Solved by the Invention] However, the wiping drying method is mainly manual labor and has low productivity, while the centrifugal separation method requires a high-speed rotation device and causes noise problems, and also has problems with compression from the nozzle. The air blowing method has the drawback of not only generating noise but also creating a poor working environment due to the scattering of attached moisture. Furthermore, in the hot air drying method, air heated by electric heat or fuel is blown using a blower, but it takes time to dry and the moisture evaporates directly from the object to be cleaned. There is an inconvenience that it remains as a stain, and there are other problems such as high equipment costs and high running costs in the heat drying method using a drying oven or the vacuum drying method.

0004

[Means for Solving the Problems] The present invention aims to solve the above-mentioned problems by placing a washed body in a drying basket, and removing moisture from the body by suction with a suction air current.
The first invention provides a method for drying a cleaning body, which comprises separating and removing moisture mixed in the suction air stream, heating it to form hot air, and drying the cleaning body by blowing it onto the cleaning body. A rotatable drying basket to be inserted, a suction nozzle with a suction opening facing the wall of the drying basket, a blow nozzle directed toward the inside of the drying basket, and a suction part connected to the suction nozzle via a moisture removal device. A second drying device for a cleaning body, characterized in that the drying device comprises:
This is an invention of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the illustrated apparatus. In Fig. 1, reference numeral 1 denotes a tumbler-shaped drying basket for storing the washed body, and its side wall is provided with many through holes 2, and its support shaft 3 is mounted on an inclined base. 4, and is held diagonally upward with the upper end side open, and is rotated by a motor 5. A suction nozzle 6 is arranged along the lower wall of the drying basket 1, and the suction nozzle 6 is connected to the strip-shaped spacers 8 and 9.
A seal body 1 made of an elastic member such as two rubber plates sandwiching the
0 and 10 are arranged side by side with holding side plates 11 and 11 on the outside and connected and integrated with each other by bolts etc., thereby creating a passage 12 for suction air flow between the seal bodies 10 and 10.
a, and a connecting port 7 is formed on one side, and the upper end edge of each seal body 10 has a suction opening 12 slightly protruding from the side plate 11 in a shape corresponding to the wall surface shape of the drying basket 1. These seal bodies 10, 10 are formed.
The suction openings 12 formed by the drying basket 1 are brought into uniform contact with the wall surface of the drying basket 1, so that the drying basket 1 is constantly slid in close contact with the seal bodies 10, 10 during rotation. The structure is such that sealing performance is maintained.

[0006] Reference numeral 13 designates flanges protruding from the connecting port 7 side of the side plates 11, 11, respectively, and the suction nozzle 6 is connected to a suction duct 14 for suction airflow through the flanges 13, 13. Reference numeral 15 denotes a moisture removal device such as a cyclone that separates and removes moisture from the suction airflow flowing through the suction duct 14. One end of the suction duct 14 is connected to the suction section 16, and a discharge section is connected to the suction section 16. A discharge duct 18 is connected to 17, and the tip of the discharge duct 18 is connected to a suction section 20 of an air blower 19 such as a blower, and a blower duct 22 is connected to a discharge section 21 of the air blower 19. Further, a heating device 23 such as a heater is attached in the middle of the air duct 22 to raise the temperature of the airflow flowing therein, and the heated airflow is ejected into the drying basket 1 at the tip side as hot air. A blow nozzle 24 is attached, 25 is a guide member provided on the base 4 to hold the suction nozzle 6, 26 is a water draining valve attached to the water removing device 15, and 27 is a cleaning body.

[0007]

[Operation] In the device configured as described above, the cleaning body 27 that has been washed with water after processing is loaded into the drying basket 1, and after the drying basket 1 is rotated by the motor 5, the blower 19
When activated, outside air is sucked through the suction opening 12, and water droplets, water films, etc. adhering to the surface of the cleaning body 27 flow into the suction nozzle 6 through the passage 12a, the connection port 7, and the suction duct 14. 16 into the moisture removal device 15. Here, the suction airflow undergoes a swirling downward and upward movement to separate and remove the mixed moisture from the airflow, and the remaining air bubbles proceed from the discharge section 17 to the discharge duct 18, and are transferred to the suction section 20 and the discharge section 21 of the blower device 19. The air flow is sent into the air duct 22 through the air duct 22.
The temperature is raised by 3 and becomes hot air, which blows into the blow nozzle 2 at the tip.
4 onto the cleaning body 27 rolling in the drying basket 1 and drying it. After the drying is completed, the operation of the blower 19, heating device 23, etc. is stopped, and the cleaning body 27 is taken out from the drying basket 1.

In addition, after loading 3 liters of workpieces having an outer diameter of 13 mm and a thickness of 0.5 mm into the drying basket 1 as described above, the air flow rate of the blower 19 was set to 3 m3/min, and the air pressure was set to 2.
As a result of drying with a hot air temperature of 60° C. and 000 mmAq, all the cleaning bodies inside the drying basket 1 were completely dried without stains or other contamination in the required time of 4 minutes. On the other hand, when drying was performed using only the hot air sent from the blow nozzle 24 without suction from the suction nozzle 6 using the above-mentioned device, it took 6 minutes for complete drying and some stains remained on the workpiece. Ta. The suction nozzle 6 may be formed into a shape that corresponds to the outer shape and dimensions of the drying basket 1, and the valve 26 is opened as necessary to remove moisture from the moisture removal device 15.

[0009]

Effects of the Invention As is clear from the above description, moisture such as water droplets adhering to the cleaning body is removed by the suction action of the suction nozzle, and this suction air flow is heated with hot air to dry the cleaning body. Not only does it leave no residue, it dries very efficiently and quickly.Furthermore, the airflow for suction and blowing is provided by a single blower, which reduces equipment costs and requires less floor space. Moreover, since the water adhering to the cleaning body is removed by suction, there is no possibility of it scattering and deteriorating the environment. In addition, the second invention has many advantages such as the fact that the entire device can be made compact and can be housed in a sealed structure, making noise countermeasures easy and running costs low.
