Description

The Dryer with Dryer for sort of Textile and sort of sheet using Microwave Dieletric Heating apparatus}

The present invention relates to a drying apparatus of a dried object such as fibers and sheets by using microwave dielectric heating, and in particular, microwave microwaves generated from the magnetron are irradiated into the microwave chamber and into the chamber where microwave dielectric heating is generated. Allow the dry material to pass through under tension or tension to allow the dry material to be heated and dried by microwave dielectric heating and at the same time to smoothly discharge the steam, so that the dry material can be dried stably and efficiently quickly. It is.

Until now, the dry items are passed through the drying chamber and dried by supplying hot air or infrared rays in the chamber, or a heating wire is installed near the dry items or a drying drum to pass hot steam to heat and then rotate. The apparatus for drying the dried material on the drum is mainly used, but they are not only able to dry the dry matter uniformly, but also have the disadvantage of low drying efficiency compared to the long drying time, and also cause the change of the dry matter. However, since the drying apparatus becomes larger, the problem of high space occupancy and high apparatus cost is a problem.

There are similar microwave drying devices with different objects to be dried, but they are used in extremely limited places. However, this drying device uses a small number of high-power magnetrons (typically microwave output of 5 kw or more) to split the output into a number of small chambers. There is a lot of interference between the furnace chamber to reduce the efficiency, as well as the use of such a high-power magnetron has a problem that the installation cost is higher than the low-power multi-chamber chamber. (5-6 times manufacturing cost)

The present invention is designed to solve the above problems by using a microwave dielectric heating to devise a device that can dry the dried matter (fibers, sheets) in a tension or tension state, which will be described in more detail with the accompanying drawings As follows.

The chamber 1 to irradiate microwaves in the 2.45 GHz band is divided up and down to illustrate that the object 11 is passed through the divided space in one or more stages (three stages in this document). The chamber 1, which has a space for passing through, is arranged in multiple stages left and right and front and rear (here, the 5 stages are illustrated as two stages front and rear), where a short microwave block is provided between the chambers 1 adjacent to the left and right. The choke (2) is connected and connected, and the front and rear adjacent chamber (1) is connected by the long microwave choke (3) so that the required number of chambers (1) in front and rear, and the last chamber (1) The multi-choke 4 for preventing external leakage of microwaves is connected to form a multi-chamber A.

On the right or left side of the left and right chambers (1), a plurality of exhaust blowers (6) are installed, and on the upper or lower part of the chamber (1), a magnetron (402) is mounted on a horizontal waveguide (401B) (Note: When the direction of the electric field was parallel to the traveling direction of the object to be constructed 11, it was called horizontal waveguide 401A (FIG. 6), and when the direction of the electric field was perpendicular to the traveling direction of the object to be constructed 11, the vertical waveguide 401B. (Referred to as FIG. 5)) and the vertical waveguide 401A, when the combined waveguide is installed in the chamber, the vertical waveguide 401A is installed in one adjacent chamber 1 and the other adjacent chamber 1 By alternately installing the horizontal waveguide 401B, the horizontal waveguide 401A and the vertical waveguide 401B are alternately installed to minimize microwave interference between the adjacent chambers 1, and to dry the dried material 11 of fibers or sheets. Net conveyor in multiple chamber (A) A tensionless dryer is constructed by installing one or more stages of the belt (7), and in the case of drying the fabric (11) of fibers or sheets in a tensioned state, rollers (8) are provided at both ends of the outer chamber (A). ) Is constructed by installing one or more stages.

The present invention, as described above, when the object to be dried, such as fibers or sheets 11 is transferred to the chamber when the space in the multi-chamber (A) in the tension or tension state by the dielectric heat dried by microwave irradiation 11) not only can uniformly dry, but also has the advantage of preventing the transformation of the product 11, the drying time is shortened, and the steam generated at the time of drying Since it can be forced out by the exhaust blower 6, there is an advantage that the drying efficiency is further increased, and the multi-chamber (A) type drying apparatus having a large capacity by easily increasing the number of the chambers 1 in the drying apparatus. It is a feature that can be easily configured.
