JPS604067Y2 - Dust removal device in the wind barrel of a grain dryer - Google Patents

Description

[Detailed description of the invention] This invention is a grain dryer that allows dust accumulated at the bottom of the wind barrel during drying work to be easily discharged to the outside of the wind barrel at the end of the work. Relating to a removal device.

A grain structure in which a storage tank, a drying tank, and a take-out tank are integrally installed one after another from above, and the take-out tank has a built-in wind cylinder equipped with a burner and whose upper part communicates with a hot air frame in the drying tank. In dryers, dust generated during drying operations accumulates at the bottom of the wind barrel.

This dust is flammable, and if a large amount accumulates after repeated drying operations, it may cause a fire in the dryer due to raw gray oil from the burner during operation, so be sure to clean it after each drying operation. However, the conventional removal work involved removing the burner and scraping it out by hand or with a hook, which was extremely troublesome.

Therefore, an object of the present invention is to provide a device that can perform the troublesome work of removing accumulated dust with ease.

In other words, the dust accumulated on the wind barrel is scraped out by an operation from the outside of the dryer, and in order to prevent the dust from getting caught in the part of the burner that causes a fire, the remaining part of the lower conveyor device is removed before the dust passes through part of the burner. To discharge from the grain outlet,
The lower conveyor device at the bottom of the wind trunk is equipped with a discharge port and a scraping device to allow dust to fall, making it easy to remove accumulated dust.One example of this will be described in detail below.In the drawing, 1 is a grain dryer. The main body includes a storage chamber 2 and a drying tank 3.
and the take-out tank 4 are stacked integrally one after another from above.

The storage tank 2 is equipped with a particle distributing device 5 suspended horizontally on the upper part, and the drying tank 3 has a hot air frame 6 disposed in the center and a hot air frame 6 disposed on both sides of the hot air frame 6, and the bottom part is provided with a particle distributing device 5 which is horizontally suspended. This is achieved by forming grain flow paths 8, 8 between the ventilation frames 7, 7, which are communicated with the tank 4, and the taking-out tank 4 is equipped with a burner 10, and the upper part thereof is connected to the dryer. A wind cylinder 9 communicating with the bottom of the hot air frame 6 inside the tank 3 is built-in, and a lower conveyor device 1 is installed at the bottom.
1 is equipped with a horizontal rack.

Above the bottom bottom plate of the wind cylinder 9, there is a raised wall 1 at the tip.
A dust receiving plate 12 having an opening 14 and a dust receiving plate 12 is provided in sliding contact with each other so as to be able to be pulled out outwardly, and when the dust receiving plate 12 is pulled out outwardly, the wind cylinder corresponding to the opening 14 is provided. The wind barrel 9 and the take-out tank 4 are communicated with each other by providing an opening 15 approximately the same size as the opening 14 in the bottom plate portion of the wind cylinder 9.

Further, at the bottom of the lower conveyor device 11 there is an outlet 17 which can be opened by means of diaphragms 16, 16 which are hinged.
17, which is configured as a dust outlet below the opening 15, as described in the claims section of the utility model registration,
At the same time, it also serves as an outlet for removing residual grains from the lower conveyor device 11.

In addition, in the figure, 18 is a grain lifting machine that connects the lower conveyor device 11 and the grain distributing device 5 in a circulatory manner, and 19 and 19 are
A rotary valve 20, which is mounted on a shaft in a communication portion between the grain channels 8, 8 and the take-out tank 4 and which intermittently sends dry grains to the lower conveyor device 11, is connected to the burner 10 of the take-out tank 4. A suction exhaust fan connected to the opposite position, 21
is an air volume adjustment plate that controls the amount of air taken into the wind cylinder 9.

Since the present invention is constructed as described above, when it is desired to remove the dust accumulated at the bottom of the wind body 9 after the drying work, the dust receiving plate 12 is moved to the outside of the body as shown in FIG. When the dust is pulled out, the dust is pushed against the air volume adjustment plate 21 by the rising wall 13 and scraped up from the back toward the front, and the openings 14 and 15 gradually overlap and are in communication with the take-out tank 4. As the amount increases, they fall into the take-out tank 4 one after another and are stored in the lower conveyor device 11.

The dust contained in the lower conveyor device 11 is removed from the slope exit 17 by operating the diaphragms 16, 16 in the same manner as the remaining grains.
．． 17, it can be ejected from the aircraft.

As described above, according to the present invention, it is much easier to remove the dust accumulated at the bottom of the wind barrel than before, and it is extremely practical for preventing dryer fires and for maintenance and inspection of the aircraft. It is true.
