Description

  The present invention relates to an air blow drying apparatus for an object to be dried which can be dried simply, quickly and inexpensively by air blow without subjecting the object to be dried after washing with heat. In particular, general cleaning baskets can be used multiple times, and the size of the items to be cleaned stored in each basket is a miscellaneous shape that is larger than the fist of an adult woman. In the case of washing with an aqueous or semi-aqueous washing liquid washing apparatus, the present invention relates to a drying apparatus necessary for drying an object to be washed after the final rinse with pure water for each basket.

  As a drying means, the hot air drying method has long been used for drying in all industries such as laundry in laundry, tea making, dried fish, shiitake mushrooms, electronic parts and the like. Even in the field of cleaning machine parts, hot air generators are also incorporated into water-based and semi-water-based cleaning devices and used for drying. However, a device to which heating means is added is expensive and not economical.

There are two background arts regarding the drying tank having a space size width of 550 mm × depth of 600 mm × depth of 400 mm.
As a heating means, the method using hot air drying has two steps of drying. First, rough water is drained in an air blow tank. Next, it is moved to a drying chamber, covered with an upper cover, and dried by sending hot air of 80 to 105 ° C.

  In this case, since 8 to 15 kW of electric power for driving the heating device is required, energy loss is large, and there is a risk of burns if an object to be dried is taken out in a heated state for shortening the time.

Even in the case of vacuum drying at 10 ² Pa or more, the drying is two steps. First, rough water is drained in an air blow tank. Next, it is transferred to a vacuum dryer, covered with a lid, and after sealing, the temperature is raised with a vacuum pump while drying to perform drying. The energy loss is large because the power of the vacuum pump is 2 to 3 kW, and the heat source is 6 to 8 kW of the indirect heating device attached to the outside of the drying tank.

  In addition, the vacuum dryer is expensive, and if an object to be dried is put in each basket, the vacuum and the temperature increase are performed after sealing, so that the drying time is too long and the efficiency is poor.

JP 2009-74717 A

  The present invention provides an air blow drying apparatus that can be dried only by air blow as a single drying tank without using heating means, achieves efficiency and energy saving, and exhibits a reliable drying effect. It is.

  In order to achieve the above-mentioned purpose, an upper surface opening portion and a front surface opening portion that open a part of the upper surface of the drying tank are provided, and are erected vertically from the center of the bottom surface of the drying tank, and connected to a driving unit outside the tank and rotated. A rotating shaft is provided, a basket cradle is provided at the upper end of the rotating shaft, a basket loaded with an object to be dried is placed, a space is formed between the bottom surface of the basket and the bottom surface of the drying tank, and drying is performed. An air blow gun with a variable spraying direction is provided at the front opening of the tank, a water collecting tank is provided at the bottom of the drying tank, and a hopper for discharging the generated mist is provided at the rear side of the drying tank. It was set as the air blow apparatus of the to-be-dried object.

  More specifically, an upper lid 2 is provided on the upper surface of the drying tank 1 so that it can be closed by about half. The drying area of the drying tank is formed by the upper surface opening part with the upper lid, the front surface opening part of the drying tank, and the space formed between the bottom surface of the basket and the bottom surface of the drying tank.

  A basket pedestal 4 is provided at the tip of a rotating shaft 3 that stands vertically from the center of the bottom of the drying tank 1, and a basket 5 loaded with an object to be dried is placed on the basket 5 and positioned in the center of the entire space in the drying tank. I tried to do it.

The rotating shaft 3 is connected to a driving unit 6 outside the tank to enable automatic rotation and reversal.
A bottom space 7 was formed between the bottom surface of the basket and the bottom surface of the drying tank, and the position of the basket was held at a height of 50 to 250 mm from the bottom surface of the drying tank.

  An air blow gun 8 is provided on the front surface of the drying tank, and the space 7 is provided in addition to the upper and center of the basket, so that the drying area is wide and air blow can be sufficiently sprayed from below the basket 5 onto the object to be dried. It has become.

  The air blow gun 8 shown in FIG. 1 shows air blow when the basket is at a certain position. In addition, what showed only the nozzle of the air blow gun 8 with the dotted line shows a mode that air can be sprayed on the whole basket from the fixed position of the front.

  Further, the air blow gun 8 can be sprayed up, down, and sideways of the basket, and the spraying can be repeated carefully by finding the shaded part where the wind pressure is difficult to reach visually, so that drying is performed accurately and reliably.

  When drying is performed, the upper lid 2 provided in the upper open portion is closed about half of the upper surface of the drying tank 1, and the rear half of the drying tank is made into a tunnel state so that it can be efficiently dried.

  The air blow gun 8 used was a pulse air shock gun in the embodiment. This pulsed air jet increases the efficiency of draining and drying the material to be dried.

By rotating the nozzle at a high speed (0.5 MPa / hour, about 5,000 rpm), pulsed air with vibrations can enter the depths of the grooves, gaps, dents, etc. of the object to be dried and quickly dried.
The generated mist is exhausted to the outside from a blower connected to a hopper 9 provided on the back of the drying tank.

The water tank 10 is provided at the bottom of the drying tank 1 and drains water.
The compressed air injected from the air blow gun is usually covered with clean dry air from the outside, but an air filter, an after cooler, and an air dryer can be used in combination depending on the situation.

  In order to further increase the drying effect, it is desirable that the temperature of the rinse water for the rinse with pure water used at the end of washing the object to be dried is warm water. Warm water has a lower water viscosity and promotes water detachment and vaporization from the material to be dried during air blowing. The change in viscosity is 1.00 mPa · s at a water temperature of 20 ° C. and 0.50 mPa · s at a water temperature of 55 ° C.

  The present invention has a sufficient drying effect by the air blow treatment in a single drying tank, and does not require two steps as in the prior art, and the steps are shortened.

  The object to be dried rotates at the center of the drying tank, and air pressure with vibration is given to the entire surface of the object to be dried by an air blow gun provided on the front surface of the drying tank, whereby water droplets are dropped and discharged from the water tank. The generated mist was discharged from the hopper, and the drying was steadily performed.

  Since the power consumption of the present invention is 0.5kW, which is a total of 0.4kW for the gear motor 0.1kW and blower, the power consumption is 1/16 or less compared to the power of the conventional heating device method (8-15kW). It can be funded and it will save a lot of energy. Although the drying time per basket depends on the shape and number of objects to be dried, the conventional method requires 10 to 30 minutes. In the present invention, since the drying time is 2 to 5 minutes, drying is shortened to 1/5 or less, so that the drying efficiency can be greatly improved.

Explanatory drawing of the right side which shows the whole air blow drying apparatus of this invention. The front view of a drying tank. The top view of a drying tank.

  The drying tank 1 is made of stainless steel and has a dimension width of 550 mm × depth of 600 mm × depth of 400 mm × thickness of 2 mm.

  In this tank, the size of the basket 5 was about 350 mm × 250 mm × depth 200 mm. A bearing holder mounting jig was manufactured in advance so that the bottom surface of the basket to the bottom surface of the drying tank was fixed to the basket cradle 4 so as to be rotatable at a height of about 200 mm.

  The specification is made of material SUS304, dimensions of 170 mm × 170 mm × 10 mm × center hole φ81 mm, and a pair of bearing holder flange holes φ5.5 tap holes × 8 are prepared.

The specific example of the structure of the drying tank 1 is as follows.
(1) A hole of φ81 mm is made at substantially the center of the bottom surface of the drying tank 1, and the bearing holder mounting jig is completely fixed by welding.
(2) The water reservoir 10 was provided on the front side of the bottom of the drying tank. Install 350mm wide x 170mm deep x 240mm deep with a 1/2 inch drain valve.
(3) A hopper 9 having a diameter of 200 mm is attached to the center of the back of the drying tank.
(4) The upper surface of the drying tank is open and the basket 5 can be taken in and out.

  An upper lid 2 capable of closing about ½ of the hopper 9 side of the upper surface opening portion of the drying tank was prepared having a width of 600 mm and a depth of 350 mm. If the basket 5 is placed on the basket cradle 4 and the upper surface of the hopper is closed with the upper lid 2 before the air blowing operation, the half of the drying tank 1 is tunneled and the mist is discharged well. The discharge is performed from the hopper 9 by a mistracer 11 provided outside the tank.

  Since the upper half of the front side of the drying tank is open, air blow by the air blow gun 8 from above is also possible.

  The height of the basket cradle 4 is provided with a space 7 of about 50 to 250 mm from the bottom surface of the drying tank 1 in order to enable air blow from the bottom of the drying tank 1. In the embodiment of the present invention, the diameter of the rotating shaft of the stainless shaft is 30 mm and the length is 360 mm assuming about 200 mm. For attachment of the basket cradle 4, a keyway is formed at the tip of the rotating shaft 3, and is joined with the keyway of the base of the basket cradle 4 and fixed with a machine key after joining.

  The basket pedestal 4 is a stainless steel shaft φ5-8mm, and metal rods are welded together in a cross-beam shape so as not to interfere with the passage of pulse air, and combined with the basket base of the rotating shaft in the state shown in FIGS. I made it.

  Insert the bearing holder containing three bearings into the hole of the bear link holder mounting jig and insert it. Align the 5.5mm x 8 holes of the bearing holder flange with the tapped holes of the mounting jig and fix them with 8 bolts.

  For attachment to the drying tank 1, the set collar is fixed at a height of about 200 mm at the bottom of the basket set by inserting the set collar into the rotating shaft 3 and inserting it into the bearing holder flange.

The drive unit 6 that drives the rotary shaft 3 uses a gear motor outside the drying tank.
The gear motor used as an example has a capacity of three-phase 0.1 kW, a reduction ratio of 1/200, and a rotational speed of 9 rpm (60 Hz).

The structure of the drive part 6 was made into the existing thing also including using a bearing holder.
The weight of the object to be dried in the basket 5 is assumed to be a maximum of 15 kg. Although the operation check was repeated with the load, the result is normal.

  Since the effectiveness of the pulsed air of the air blow gun 8 is an essential condition that the wind pressure is accompanied by vibration, the effective distance of vibration is measured. Its effectiveness is perceived by tactile sensation on the palm.

The effective distance is the distance from the tip of the pulse air shock gun until sufficient vibration is felt on the palm. The pulse air shock gun was confirmed by two models of Galue Co., Ltd.

  When the distance between the two models is more than about 15 cm from the effective distance, the vibration is attenuated and becomes the same as the wind pressure of a small fan, and the blown air has the effect of promoting mist exhaust from the hopper.

  The air blaster is superior in terms of functionality, but the air blaster mini is used because the overall length of the nozzle is 15 mm long and the handling of the drying tank of the present invention is slightly worse. When using a basket larger than the embodiment of the present invention, an air blaster is used.

  The ability of the blower connected to the hopper 9 of the drying tank is selected from the opening area of the front surface of the drying tank (refer to blower manufacturer Showa Denki Co., Ltd.).

Since the mist generation source in the drying tank is almost exposed, the formula for calculating the air volume when the wind speed is set as high as about 7 to 15 m / min is as follows.
Opening area (m ² ) x wind speed (m / min) = air volume (m ³ / min)
0.35 7-15 2.5-5.3

Since the maximum air volume from the pulse air shock gun is 0.25 m ³ / min as described above, adding this air volume gives 2.75 to 5.55 m ³ / min. Therefore, in the embodiment of the present invention, Mistresa manufactured by Showa Denki Co., Ltd., CRH-H04, power supply 3-phase 200 V, output 0.4 kW, maximum air volume 6.6 m ³ / min (60 Hz) was used.
(Industrial application fields)

  In current cleaning methods, dichloromethane and trichlorethylene, which are harmful to the human body, are used as cleaning agents, both of which are converted to aqueous cleaning methods. However, since the current method of drying the object to be cleaned is a problem, the air blow drying device of the present invention can promote the conversion to the water-based cleaning method. Moreover, it can be used as an air blow drying device attached to a cleaning device, and can also be incorporated into an ultrasonic cleaning device for water containing a silicon-containing cleaning function.
