Description

[Detailed explanation of the idea] This invention relates to a dust drying device for a dust remover.

Conventionally, the base for storing the dust dropped from the rake of a dust remover was made of concrete as shown in Japanese Patent Publication No. 45-24431, so the ventilation conditions were extremely poor and it was difficult to dry the dust naturally, resulting in corrosion of the dust. The problem of bad odors is becoming more and more serious.

Therefore, the applicant focused on the fact that the lateral wind blowing on the screen is blocked by the screen and changes to blowing up from the bottom to the top at the rear of the screen, and using this blowing up wind to naturally dry the dust that has fallen from the rake and is discharged. It is an object of the present invention to provide a drying device that makes it possible to eliminate the above-mentioned conventional drawbacks.

That is, one embodiment of the structure and operation of this invention, as shown in the illustrative drawing, comprises a screen 13 provided in the longitudinal direction of the waterway and an oblique direction, and a rotary rake, and the rake rises along the screen par 14 of the screen 13. 4 is located above the screen 13 and is moved to the rear of the screen 13 by the guide of the guide sprockets 3 and 15, and is provided with a dust remover 6 which rotates and moves forward and then descends. A drying plate 9 with a large number of ventilation holes 16 scattered at a position above the water surface is widely installed over the entire width of the waterway, and a deterrent plate 10 is erected at the front end of the drying plate 9, so that a distance from the deterrent plate 10 is set. At the rear position where the water is placed, the debris that is discharged from the rake 4 and spread on the drying plate 9 is dried by the ventilation that blows upward from the water surface.

In the figure, 1 is a driving sprocket provided on the support base 7, 2 is a driven sprocket provided on the side wall 8, 5 is a conveyor chain provided with a rake 4, and 11 is a motor 11 connected to the driving sprocket 1 by a transmission belt 12. It is.

Note that the drying plate 9 may be the whole or a part of the base.

The conveyor chain 5 is rotated by the operation of the motor 11, and the rake 4, which rises along the front surface of the screen 13, scrapes up and collects the dust adhering to the screen par 14, and moves the guide sprocket 3.15. The rake 4 is rotated by the drive sprocket 1 and moved forward and lowered. At this time, the rake 4 is rotated by the drive sprocket 1, so that the dust in the rake 4 is removed from the drying plate. 9 and discharge it.

In this way, the dust discharged from the rake 4 which moves behind the screen 13 and rotates at intervals from the deterrent plate 10 is spread on the drying plate 9 as shown in Fig. The strong ventilation will dry it and completely eliminate the foul odor caused by corrosion.

Therefore, post-treatment of this type of garbage can be carried out very easily.

Since this invention has the above-mentioned configuration, it exhibits the following effects.

That is, a drying plate 9 with a large number of ventilation holes 16 scattered at a position above the water surface behind the screen 13 is installed across the entire waterway width, and then the rake 4 is moved to the rear of the screen 13 and then rotated. In order to discharge the garbage by falling, the garbage is spread on the drying plate 9, and the air blowing from below to the upper direction spreads over the entire garbage and effectively dries it.

Moreover, the water draining effect from the ventilation hole 16 is also performed well.

However, since the Japanese Patent Publication No. 45-24431 uses a concrete housing, dust accumulates in the concrete housing and the concrete housing becomes almost sealed, resulting in severe rot and bad odor.

In this regard, in this invention, since the drying plate 9 having ventilation holes 6 scattered therethrough is installed flat over the entire waterway width, the discharged garbage is spread over the upper surface of the drying plate 9, and a good drying effect can be obtained.

More specifically, this invention is based on the drying plate 9 which has a large number of ventilation holes 16 scattered above the horizontal position behind the screen 13.
By constructing a dryer plate 9 and having a restraining plate 10 erected at the front end of the drying plate 9, the air flowing in from the front of the screen 13 first passes through the screen 13, and then a part of it is blocked by the restraining plate 10. Other air is deterrent plate 1
0, the dust passes through the ventilation holes 16 of the drying plate 9 and dries the dust on the drying plate 9.

This is because a vortex is generated on the rear side of the deterrent plate 10 and the dust on the drying plate 9 can be dried because the vortex moves around the vortex.

In this regard, the dust remover disclosed in Publication No. 47-20104 has a screen cylinder installed parallel to the length direction of the waterway, so the wind blowing horizontally cannot be changed vertically by the screen cylinder, so the ventilation drying effect is poor. I can't wait.

Moreover, since the dust accumulates in the extremely small parts, even if wind blows up against the board, it is almost impossible to create ventilation.

In addition, in the above-mentioned conventional publication, the dust is immediately dropped and discharged near the top of the screen, so the dust accumulates in the immediate vicinity of the screen, and the lateral wind passes through the dust before being converted into an upward wind. You cannot expect a drying effect.

As described above, this invention has the screen 14 installed in a direction diagonal to the length direction of the water channel, so that the wind blowing horizontally changes to blowing upward when it passes through the screen.

Also, the rake was moved backwards from the screen to allow the dust to fall once the direction of the wind had completely changed.

Furthermore, in order to spread the discharged garbage and provide good ventilation, the screen is constructed above the water surface behind the screen 14 over the entire width of the waterway.

In addition, since the air from the screen 13 generates a vortex by the suppression plate 10 and is dragged by this vortex, the air passes through the ventilation holes 16 of the drying plate 9 and dries the garbage. The garbage on top 9 is dried.

Therefore, moisture is removed from the garbage, making it lightweight and easy to transport, and corrosion of the garbage is prevented, causing no foul odor, etc., and improving workability for removing the garbage.
