Description

[Detailed description of the invention] The present invention relates to a single-layer circulating grain drying device.

Among humidity-controlled grain dryers, in the circulation type, the inside of the down-flow grain drying chamber formed inside the drying section, or the rotating shaft installed at the lower end of the drying chamber. Straw debris, etc., can sometimes land on the rotor blades or shaft of the valve, so in order to remove this, the conventional method was to remove the top canopy of the dryer, go inside, and clean the perforated plate. The rotary valve was being cleaned.

However, the work of removing the canopy was not only quite troublesome because there was an upper conveyor connected to the elevator, but also the footing was poor once inside the narrow humidity control tank, making it impossible to completely clean the tank.

Therefore, when drying rice grains and then drying wheat, residual rice grains would be mixed in with the rice grains.

Further, among the humidity control type drying apparatuses, there is a one-layer type drying apparatus having only one row of down-flow type grain drying chambers, such as the one described in Japanese Utility Model Application Publication No. 78462/1983.

This type of device still has many problems with cleaning and the like.

Therefore, the present invention particularly provides a vertical flow-down type in which a humidity control tank is formed inside a humidity control section at an upper position, and a drying section at a lower part of the humidity control section is formed with vertical perforated plates on both sides. Only one row of grain drying chambers is provided in the center of the left and right sides, and a V-shaped gutter is provided on one side diagonally below the lower end of the drying section. A spiral conveyor is installed horizontally on the upper surface of the V-shaped gutter. A lift is installed on the side,
The end of the spiral conveyor is connected to the lower part of the elevator, the discharge gutter at the upper part of the elevator is connected to the humidity control tank to enable circulation drying, and the outer swash plate of the V-shaped gutter is connected to The lower end of the outer swash plate is pivoted to the bottom of the V-shaped gutter, and the outside portion of the V-shaped gutter on the outer wall of the aircraft body is cut out to form a window across the entire width, and the outer swash plate has an upper end that is connected to the window. The gist of the present invention is to have a structure of a single-layer circulating grain drying device that can be opened and closed from 1'υ facing the 7S++ to the open position that is closer to the bottom than the bottom of the V-shaped receiving gutter, and eliminates the inconvenience of the known example. It has been resolved.

To explain with the diagram, 1 is the upper humidity control section, 2 is the humidity control section 1
Below = ++ is the drying section, and 3 is the grain collecting section at the bottom. The humidity control section 1 of the upper tg++ is mainly a humidity control tank 4, which is formed in a rectangular empty chamber made of a thin iron plate. Drying section 2 at the bottom
A single row of downflow type grain drying chambers 5 is provided in the center. Both side walls of the down-flow grain drying chamber 5 are formed of nets or perforated plates 6, 6. A hot air supply candy chamber 7 is formed on one side of the downflow type grain drying chamber 5, and a hot air exhaust chamber 8 is formed on the other side.

The -L end of the downflow type grain drying chamber 5 is connected to the lower end of the humidity control tank 4. At the lower end of the down-flow grain drying chamber 5,
A rotary valve 9 is attached to discharge grain toward a hot air exhaust chamber 8.

A V-shaped receiving trough 10 is provided in the grain collecting section 3 at the lower part of the drying section 2. On the lower side of the rotary valve 9, the above-mentioned V
One side of the mold receiving trough lO is connected. The V-shaped receiving gutter 10 is located directly below the center of the hot-air exhaust chamber 8, and is biased toward the other side when viewed as a whole. The V-shaped receiving trough 10 is sloped lower toward the center, and a spiral conveyor l is located in the northern part.
1 horizontally.

Reference numeral 12 denotes an elevator, which is vertically erected on the side of the machine body, and the discharge end of the spiral conveyor 1l is connected to the lower end of the A-elevator 12. The discharge gutter 13 at the upper end of the elevator l2 communicates with the upper conveyor 14, and supplies grain to the humidity control tank 4 via the -1 two-part conveyor 14.

Thus, the outer machine wall 15 of the V-shaped receiving trough IO is cut out to form a window 16. The windows 16 are formed across the entire width in the front-rear direction. The outer swash plate l7 of the V-shaped gutter 10 is
It is pivoted 19 to the bottom l8 of the mold receiving trough 10, and its tip protrudes from the window 16 and opens outward. That is, the upper end of the swash plate 17 can be opened and closed from a position where it joins to the upper edge of the window l6 to a position lower than the bottom part 18.

In addition, 20 is a suction fan, 21 is a burner, 22 is a hopper, and 23 is a pin.

Next, the action will be described.

When undried rice is loaded into the loading hopper 22 of the elevator 12, it rises inside the elevator 12 and then passes through the discharge gutter 13 to the upper conveyor 14 into the humidity control tank 4 and the down-flow type grain drying chamber 5. Be staked out. So I lit the 2L burner,
When the suction fan 20 is rotated and hot air is supplied from the hot air supply chamber 7 into the downflow type grain drying chamber 5, the downflow type grain drying chamber 5
The unhulled rice inside is partially dried by blowing hot air. However,
When the rotary pulp 9 is rotated at a constant cycle, the dried unhulled rice is fed out little by little by the rotation of the rotary hull 9 and is discharged onto the V-shaped receiving trough lO, and then transported across by the helical conveyor l1 to the elevator l2. It flows into the lower end, ascends in the elevator 12, and is re-filled and returned to the humidity control tank 4.

The piled up unhulled rice gradually flows down and flows into the down-flow type grain drying chamber 5 again, undergoes second drying, and is piled up again into the humidity control tank 4.

When this drying is repeated about 4 to 6 times, the humidity control drying is normally completed.

However, when the humidity control drying is finished, the loose straw etc. may stick to the perforated plates 6, 6 forming the down-flow type grain drying chamber 5, or become entangled with the blades of the rotary 8-rube 9 or the spiral conveyor 11. However, in that case, pull the pin 23 to open the swash plate 17 from the position shown by the solid line in Figure 1 to the position shown by the phantom line, and put the upper body inside to clean it.

Further, if the swash plate l7 is fixed halfway as shown in FIG. 1, tensioning can be performed.

Among conventional humidity control type grain dryers, in the circulation type, the rotary valve is installed inside the down-flow grain drying chamber formed inside the drying section, or at the lower end of the drying chamber. In order to remove this, conventionally the
They removed the top canopy of the drying equipment and went inside to clean the perforated plates and the rotating pulp. However, the work of removing the canopy was not only quite troublesome because there was an upper conveyor connected to the elevator, but also the footing was poor once inside the narrow humidity control tank, making it impossible to completely clean the tank. Therefore, when rice is dried and then wheat is dried, residual rice grains are mixed into the wheat. Further, among the humidity control type drying apparatuses, there is a one-layer type drying apparatus having only one row of down-flow type grain drying chambers, such as the one described in Japanese Utility Model Application Publication No. 78462/1983. Especially in this form! There were many problems with cleanup, etc.

However, in the present invention, a humidity control tank 4 is formed inside the humidity control section l at the upper position, and a vertical perforated plate 6 is formed on both sides of the drying section 2 at the lower part of the humidity control section 1. Only one row of downflow type grain drying chambers 5 is provided in the center, a V-shaped receiving gutter 10 is provided diagonally below the lower end position of the drying section 2, and a spiral conveyor l1 is installed horizontally on the upper surface of the V-shaped receiving gutter lO. , R exit 1 on the side of the aircraft
2 is provided, and the end of the spiral conveyor 1l is connected to an elevator l2.
The upper discharge gutter l3 of the elevator l2 is connected to the humidity control tank 4 for circulation drying, and the lower end of the outer swash plate l7 of the V-shaped gutter 10 is connected to the lower end of the outer swash plate l7 of the V-shaped gutter 10. At the bottom l8, the shaft attachment 19L and the outside part of the receiving trough l0 on the outer wall of the fuselage are cut out to form a window 16 across the entire width, and the swash plate 17 faces the upper part of the window 16. Since the structure of the single-layer circulating grain drying device is such that it can be opened and closed freely from the open position lower than the bottom part l8 of the receiving gutter, the difficult cleaning work can be easily carried out. In particular, in the present invention, a window 16 is formed in the machine wall 15 of the lower grain collecting section 3, and the swash plate 17 of the V-shaped receiving gutter 10 is opened outward for cleaning. Since the height is suitable for working, cleaning work is easy, and subsequent assembly is also easy, and if it is fixed halfway, it can also be tensioned. .
