Description

[Detailed description of the invention] Industrial applications The present invention relates to a dust removal device in a grain dryer.

Problems to be Solved by the Invention The grains are fed out by rotating the helix in the transfer gutter and flowing down from the storage chamber in the upper part to the drying chamber in the lower part, from the end of the transfer gutter, through the shell lifter, and into the storage chamber. In a dryer that dries by passing hot air generated by a burner into the drying chamber while circulating it, it is possible to remove straw waste mixed into the dried grains,
It is difficult to remove dust, etc., and as a result, poor circulation may occur due to the influence of straw, dust, etc., and the drying rate may become unstable.

Means for Solving the Problem The present invention provides for transferring grains fed from an upper storage chamber (1) through a lower ventilation drying chamber (2) into a transfer gutter (3) at the lower end of this drying chamber (2). In this dryer, the grain is dried while being fed out from the transfer end side to the shell raiser (5) by the rotation of the helix (4).In one side of the drying chamber (2), a transfer gutter (3 ) on both front and rear ends of the exhaust machine (
6) through dust exhaust ports (7) and (8), respectively.

Functions and Effects of the Invention The grains are allowed to flow down from the upper storage chamber (1) to the drying chamber (2) and the transfer gutter (3), and then raised using the helical screw (4)! (5) While circulating the grains, they are dried by hot air that is passed through the drying chamber (2) from the eight-hole dryer.During this circulation drying, straw, dust, etc. The dust is sucked in by the exhaust fan (6) through the two dust exhaust ports (7) and (8) provided at the front and rear of the chamber (9) and discharged outside the machine, thereby stabilizing the circulation and stabilizing the drying speed.

Embodiment In the illustrated example, the wall of the dryer (lO) has a rectangular shape in a plan view that is long in the front-rear direction, and has front and rear wall plates (11).

(11) and left and right wall plates (I2) and (12), and has ceiling plates (+3) and (13) on the upper part of this truss,
An operation box (14) is detachably attached to the front wall plate (I1).

A transfer gutter (3) which is located in the center of the machine wall and extends in the front and back direction and has a built-in helix (4) that feeds and transfers the grains and has a mouth-shaped shape when viewed from the front is provided, and this transfer gutter (3) At the top, a V-shaped drying chamber (2) (2) is formed between the upper and lower ventilation mesh plates with approximately constant width on the upper and lower sides, and communicates with the upper and lower ventilation mesh plates. A mountain-shaped inclined plate is provided between the upper and lower ventilation mesh plates, and this inclined plate and the upper ventilation mesh plate form a ventilation chamber (
15) and a burner (
16), the right wall plate (12) in front view, the lower ventilation net plate and the lower partition plate (17) form an exhaust chamber (9), and the left wall plate (+2) in front view , the lower ventilation mesh plate and the transfer gutter (3) - the partition plate (18) connected in series with the uneven weight form a ventilation fence (9), and the ventilation fan provided on the rear wall plate (11). (
6).

A dust exhaust port (8) is provided at the front end of the partition plate (I8). The rear wall plate (11) forming the air exhaust chamber (9) has a dust exhaust port (7), and the dust exhaust port (7) and the air exhaust a (6)
A dust exhaust pipe (24) is provided between the
7), the dust is sucked and discharged by the exhaust fan (6) through the dust exhaust pipe (24). A storage chamber (1) is formed in the upper part of the drying chamber (2), (2), and an upper helical transfer gutter (IS) is installed along the ceiling plate (13), (13) above the storage chamber (1). This upper helical transfer gutter (19)
A supply port for supplying the transferred grains into the storage chamber (1) is opened in the center of the storage chamber (1), and a diffusion plate (20) is provided at the bottom of this supply port.
is provided, and the grains are transferred to the fat retention chamber (1) using this diffusion plate (20).
It is configured to diffuse and reduce inward.

An exhaust fan (6) is provided at the lower part of the partition plate (18) in the front part of the inner wall a, and the front end of the partition plate (18) forming the exhaust fan (6) and the ventilation chamber (9) The dust exhaust port (8
) is provided in communication with the dust exhaust pipe (24), and the straw 14, dust, etc. mixed into the grains during circulation drying are removed from the dust exhaust port (8). ) to the exhaust machine (6)
The structure is such that the liquid is sucked in and discharged to the outside of the machine via the discharge tube (25).

The elevator (5) is removably attached to the front part of the front wall slope (11), and a packet conveyor (21) belt is stretched between the upper and lower pulleys inside, and the upper end and the upper helical transfer gutter(
19) A dispensing tube (22) is removably provided between the starting end and the transfer gutter (3) for communication, and a supply gutter (23) is provided between the lower end and the terminal end of the transfer gutter (3) for communication. , the spiral (4) is transferred through the transfer gutter (3), and is also supplied into the shell elevator (5) via the V8 gutter (23).

In addition, a dust exhaust port is provided on one side of the supply gutter (23), and the fJL is passed through the exhaust WL machine (6) provided at the bottom of the partition plate (1B) to suck in and discharge straw and dust. You may also do so.

The hot air generated from the burner (1B) installed on the front wall plate (11) is sucked by the exhaust fan (6) installed on the rear wall plate (+1), and the grains stored in the drying m(IQ) are The grains are dried by being exposed to the hot air while flowing down the drying chamber (2), and are transferred while being fed out through the helix (4) and the transfer gutter (3).
It is transferred and discharged into the supply gutter (23), transported to the upper part by the shell lifter (5), and then transferred to the upper helical transfer gutter (19) to the diffusion plate (20).
), the grains are evenly diffused and returned to the storage chamber (1) by the diffusion plate (20), and when the grains are circulated and dried to reach the specified moisture content, they are automatically cleaned by the operation box (14). The dryer (10) will automatically stop, but the straw, dust, etc. that get mixed into the grain during this circulation drying will be removed through the dust exhaust ports (7) and (8) provided in the ventilation chamber (9). ) from the exhaust fan (6), (
6) is sucked up and discharged outside the machine.
