Assembly structure of hot air spray nozzle of dryer {ASSEMBLY STRUCTURE OF HOT WIND NOZZLE FOR DRY MACHINE}

The present invention relates to a hot air jet nozzle of a dryer, and more particularly, to a hot fabric in a dryer used to perform a drying process or a shrinkage process by heat treatment to supply high temperature hot air to a fiber fabric. The present invention relates to an assembly structure of a spray nozzle which performs a role of directly spraying on a.

In general, in the various processes carried out during the production of the fiber, the fibers that are dyed and printed are wetted by the dye solution, so that the fibers are rapidly dried and shrunk using a hot air drying apparatus and then transferred to the next process.

As a device for performing such a drying process, a dryer is mainly used to perform a drying process and a shrinkage process by heat treatment. In FIG. 1 and FIG. An example is shown.

That is, the conventional fiber drying dryer is provided with a drive motor M at one side of the lower side of the rectangular chamber 1 having a substantially rectangular parallelepiped shape, and the blower fan 3 is provided on the motor shaft 2 of the drive motor M. This is fixed.

Here, the blowing fan 3 is a fan (Fan) is formed so as to be blown in a direction perpendicular to the suction direction of the air. On the lower side of the rectangular chamber 1 corresponding to the opposite side on which the drive motor M is installed, a radiator R or a gas burner may be provided as a radiator for performing heat exchange with the flowed air.

Between the radiator R and the blowing fan 3 of the driving motor M, a duct member 4 through which air flows is fixed, but one end thereof is installed to surround the entire blowing fan 3. When the blowing fan 3 is rotated by the driving of the driving motor M, the heat passing through the radiator R serves to guide suction flow to the blowing fan 3 in the direction of the arrow.

The hot air duct 5 which is connected to the upper side is branched and installed in the duct member 4 in which the blowing fan 3 is installed, and the heat generated from the radiator R is switched to the hot air by the blowing fan 3. It is introduced into the hot air duct (5).

Specifically, the hot air duct 5 is composed of a pair of upper and lower branch ducts 5a and 5b configured to be spaced apart from each other at predetermined intervals up and down, and are spaced apart from each other to maintain a predetermined interval up and down in connection with the upper and lower branch ducts 5a and 5b. The upper and lower guide ducts 6 and 7 for spraying hot air into the fabric are fixedly installed.

The upper and lower guide ducts 6 and 7 have a structure in which the inside is sealed to the outside, and the nozzles 8 having a plurality of fine injection holes are formed at the upper and lower sides facing each other, and the hot air guide duct 5 Hot air transported through) is injected through the injection nozzle 8 in which fine injection holes are formed to reach the fiber fabric passing between the upper and lower guide ducts 6 and 7.

Therefore, the fiber fabric in the contracted state by the hot air is adjusted to a constant width to prevent deformation of the product.

In the figure, reference numeral 9 denotes a filter for collecting the foreign matter in the air that is injected onto the fiber fabric through the injection nozzle 8 and then circulated to the radiator R side again.

On the other hand, when looking at the structure of the conventional injection nozzle (8) in more detail as shown in Figure 3 in the two-row injection structure is coupled to the connector 7 'side of the guide duct (7) in the slide method, the injection nozzle (8) The distribution plate 8a having a concave-convex shape is inserted in the inside so that the hot air spraying pressure to be sprayed can be uniformly distributed.

However, the distribution plate (8a) is to form a constant irregularity spacing (d) by the molding in the manufacturing process, the uneven spacing (d) is not kept constant due to the nature of the molding operation, the injection of hot air is uneven Will be done.

Therefore, when the non-uniform injection is made in the injection nozzle (8) there is a problem that causes a defect in the heat treatment and dry state of the fiber fabric.

The present invention has been proposed to solve the above problems in the prior art, by providing a spray nozzle assembly structure that can be uniformly spraying of hot air to ensure that the heat treatment and dry state of the fiber fabric is always maintained in good condition There is a purpose.

The object is a nozzle housing having a plurality of incisions are formed to maintain the same interval constant along the longitudinal direction; It is possible to achieve through the injection nozzle assembly structure constituting a configuration including a; distribution plate is inserted and coupled to each cut portion partitioning the injection space.

Hereinafter, a specific embodiment of the present invention will be described with reference to FIGS. 4 to 6.

The injection nozzle 18 according to the present embodiment has six assembly structures as shown in the exploded perspective view of FIG. 4 and the component views shown in a, b, c, d, and e of FIG. 5, respectively. Same as

First, a nozzle housing 10 for branching hot air delivered through the guide ducts 6 and 7 into two rows is formed with a cutting groove 10a for maintaining a uniform gap in the lower portion as shown in FIG. 5A. In the shape of a "V" in the form of a predetermined length, the nozzle housing 10 has a side guide plate (11, 12) is formed in the lower side as shown in Figure 5b the slide support (11a, 12a) is formed symmetrically mutually By being coupled to both sides in a state of forming a guide passage of the injection hot air together with the nozzle housing 10 in two rows.

In addition, as shown in FIG. 5C, each of the cutting grooves 10a of the nozzle housing 10 is inserted into and coupled to a distribution plate 15 having a shape capable of simultaneously partitioning two rows of flow paths, thereby providing hot air along the longitudinal direction of the spray nozzle 18. It can be seen that the injection amount of can be uniformly distributed.

On the other hand, the injection nozzle 18 is to be slidingly coupled with the connector (7 ') of the guide duct (7) side, as shown in Figure 6, for both ends of the nozzle housing 10 for this purpose The blocking plates 13 and 14 having the same shape as 5e are coupled to each other. In this case, the front side blocking plates 13 are supported on the side guide plates 11 and 12 as shown in FIG. 5D. ) To achieve a shape that does not cause interference with the connector 7 'through the front end side, and the rear end blocking plate 14 has the support parts 11a and 12a as shown in FIG. By forming a shape that can hide the to act as a stopper for fixing the sliding coupling.

It is preferable that the coupling between each assembly constituting the assembly structure is made by welding.

The injection nozzle 18 of the present invention, which constitutes such a technical configuration, has a constant spacing (d1, d2, d3 ....) between the cutting grooves 10a of the nozzle housing 10, so that the distribution plate 15 is provided. It can also be seen that they are always equally spaced.

That is, the cutout groove 10a is formed by precise dimensional measurement during the design and manufacture of the nozzle housing 10, so that deformation of the gap between the cutout grooves may occur in an assembling process with the distribution plate 15 thereafter. Since the spacing of the distribution plate 15 can also be maintained uniformly.

Therefore, when hot air guided through the guide ducts 6 and 7 is injected as shown in FIG. 1, the hot air can be evenly and uniformly sprayed along the entire length of the injection nozzle 18.

In addition, although specific embodiments of the present invention have been described above, it is obvious that the injection nozzle assembly structure of the present invention may be variously modified and implemented by those skilled in the art.

However, such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended claims of the present invention.

As described above, the spray nozzle assembly structure of the present invention allows the hot air pressure applied to the spray nozzle of the dryer to be uniformly made at all times according to the installation position of each nozzle and the length of the nozzle. It shows the effect that can be maintained well.
