Abstract

PROBLEM TO BE SOLVED: To provide a barrel type drying machine which achieves power saving, space saving, manpower saving, and speeding up of a treatment process, by drying a small component of which the surface has been treated with plating or the like in the barrel and washed in the water, without taking it out once from the barrel. SOLUTION: This drying machine is characterized by having a barrel 2 which is manufactured from a plastic material for bearing 100 deg.C with molding or machining, so as to have a taper 16 on a slit slot 14 for letting air pass through, attaching a rotation mechanism 27 for rotating the barrel 2 slowly, outside of a drying tank 39, and providing a register 40 and a register 41 for passing hot-air mainly to the barrel 2 at high speed in one way in the drying tank 39.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barrel-type dryer in which small parts having been subjected to surface treatment such as plating with a barrel are washed with water, and then the small parts are dried as they are without being taken out of the barrel.

[0002]

2. Description of the Related Art As a drying means for a small component which has been subjected to surface treatment such as plating with a barrel, the small component is first taken out from the barrel, and then removed by a centrifugal dehydrator, a basket, a net conveyor, or the like. I have.

[0003]

The conventional method has the following problems. B. There is manual labor to remove small parts from the barrel once. B. When removing small parts, impact is given and small parts are damaged. C) The small parts are damaged due to the high speed rotation of the centrifugal dehydrator. D. When removing small parts from the centrifugal dewatering machine, it also requires manual labor and causes damage. (E) Separate lines for drying means, requiring a large space.

[0004]

A barrel 2 has the same type as that used in the conventional surface treatment line such as plating and is used in FIGS. 15.16.17. And hot air is strongly blown through the barrel 2 and the small parts 1 placed in the barrel 2 from one way 47. A barrel-type dryer that dries by spraying on 48.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments according to the present invention will be described below in detail with reference to the drawings. Although the barrel type dryer according to the present invention can be used alone, it can be incorporated in the conventional plating lines shown in FIGS. 1 and 2. The material of the barrel 2 is made of plastic that can withstand up to about 100 ° C., the slit thickness is set to 5 mm to 10 mm, the center part 17 of the thickness is set to a required dimension 15, and the inner surface of the barrel is Required dimensions 15
And taper 1 to 5 to 10 degrees for the outer surface
6. A molded or machined one is used. The required dimension 14 is 1 mm in width according to the shape of the small part 1.
10 mm and a length of 5 mm to 50 mm. The barrel is attached to the hanger 23 corresponding to the carrier 31 and the side plate 21 via the boss 18 in the same manner as that used in the surface treatment of the conventional barrel or the like in FIGS. The shaft 24, the gears 6, 22 and the gears or sprockets 25 are attached and transmitted by a rotation mechanism 26, 27 attached to the outside of the drying tank 39, so that the barrel 2 can be changed from 1 rotation to 10 rotations per minute. The number of the barrels 2 to be placed in the drying tank 39 is set so that the drying time can be set to 10 to 20 minutes depending on the shape of the small component 1.
Take out the barrel 2 put in the tip, and then put the barrel 2
And put them in front. Outside the drying tank 39, a high-pressure blower 44 is attached to circulate hot air. The performance of the barrel 2 and the small parts 1 in the drying tank 39 room, select a model that can obtain a wind speed 47 of 10m ~ 20m per second, near or behind the high-pressure blower,
A heating unit 45 such as electricity / steam / gas for heating and a microfilter 4 for purifying air.
3 and a suction duct 42 and a ventilation duct 46 for circulating hot air. In the drying tank 39, a hot air sent from a blow duct 46 adjusts a directivity 47 toward the barrel 2 and a register 40 is attached. On the opposite surface, a hot air direction 48 coming from the cash register 40 is attached. Adjust, attach the register 41.

[0006]

As described above, the barrel type drier of the present invention can be incorporated into a line, and has the effects of requiring no manpower, not being damaged, not taking up space, etc., and surface treatment. Rationalization and labor saving at factories.
