Description

[Detailed description of the invention] [Industrial application field] In the invention, dust is absorbed by an annular flange in which a suction port of a turbo type exhaust fan is fitted to a side wall of an exhaust chamber by its own weight operation by hooking the turbo type exhaust fan. Press it so that it matches the mouth,
The present invention relates to a blower mounting device for a grain dryer which allows efficient discharge operation without pressure loss, or which can be easily attached and detached.

[Prior Art] Conventionally, an exhaust fan connected to an exhaust chamber is detachably attached to an exhaust chamber side wall, and a suction exhaust fan is rotatably stored on an intake side of the exhaust fan. The air exhaust device in the rice drying machine, which is equipped with an air exhaust tube and exhausts the exhaust air in the exhaust air chamber to the outside through the exhaust air housing and the exhaust air tube by the suction action of the suction exhaust air blower, Prior to the present application, it is known, for example, as described in Japanese Utility Model Laid-Open No. 59-189092.

[Problems to be Solved by the Invention] By the way, in the conventional exhaust device of the seed rice drying machine, the suction exhaust operation is always performed through the exhaust housing, so that the exhaust air is exhausted during the suction exhaust operation. Dust and the like are deposited on the corners of the housing without being discharged, which causes a pressure loss as a static suction pressure, which significantly deteriorates the performance of the suction and exhaust fan, and also removes the dust from the storage of the suction and exhaust fan. There is a problem in that the vibration noise is allowed to be high because the wind cylinder is mounted on the exhaust casing, and the mounting operation is troublesome.

The present invention has been made in view of such problems of the prior art, and has as its object to minimize the pressure loss as a static suction pressure and to improve the exhaust performance of a turbo-type exhaust fan. An object of the present invention is to provide an exhaust fan mounting device for a grain dryer in which remarkable improvements are made, vibration noise is less generated, and mounting of a turbo-type exhaust fan can be easily and reliably performed by a one-touch hooking operation.

[Means for Solving the Problems] In order to achieve the above object, an exhaust fan mounting device in a grain dryer according to the present invention is provided at an opening of a side wall of an exhaust chamber,
The dust suction port is opened, and an annular flange fitted with a packing is fitted on the peripheral surface of the opening, and a horizontal hook fitting having a plurality of hooks projecting upward is attached to the side wall above the annular flange, and A turbo-type exhaust fan with a suction port approximately the same diameter as the dust suction port is detachably attached to the hooking projection, and the upper edge of the exhaust fan mounting casing, which is freely attached, is hooked, and the suction port is operated by the weight of the turbo-type exhaust fan. It is pressed against the dust suction port.

[Operation] An opening is provided in a side wall of an exhaust chamber provided at a lower portion of a dryer body, and a horizontal hook fitting having a plurality of hooking protrusions projecting upward is attached to an upper side wall of the opening. An annular flange fitted with packing on the peripheral surface of the opening of the dust suction port is fitted into the opening. Next, the upper end edge of the exhaust fan mounting casing of the type in which a turbo-type exhaust fan having an intake port having substantially the same shape as the dust suction port opened in the center front surface is detachably attached is hooked so as to hang on the hook projection. If you let go,
The suction port is pressed into contact with the dust suction port via the packing by the own weight of the turbo-type exhaust fan, and the exhaust chamber and the turbo-type exhaust fan are connected.

Therefore, when the turbo-type exhaust fan is operated, the turbo-type exhaust fan is directly mounted on the side wall of the exhaust air chamber without providing a conventional exhaust air casing, which causes a pressure loss as a suction static pressure. The exhaust air in the exhaust chamber can be efficiently exhausted without any trouble, the vibration can be reduced, and the installation and removal of the turbo-type exhaust fan can be easily and quickly performed by one-touch operation.

Example An example will be described with reference to the drawings.

In FIG. 1 to FIG. 4, reference numeral 1 denotes a dryer main body capable of drying grains by flowing hot air, and an air blower provided in a lower portion of the dryer main body 1 after being subjected to drying. Is provided. An opening 4 having an appropriate diameter is opened in the side wall 3 of the exhaust chamber 2, and the opening 4 is fitted with an annular flange 5 having a packing 7 mounted on the opening edge surface of the dust suction port 6.
A horizontal hook 8 having a plurality of hooks 9 projecting upward is attached to the side wall 3 above the opening 4. Reference numeral 10 denotes a turbo exhaust fan in which a suction port 12 is opened at the center front of the main body 11 and a turbo impeller 13 is rotatably stored therein.The turbo exhaust fan 10 is detached from an exhaust fan mounting casing 14. It is freely attached. The exhaust fan mounting casing 14 has an upper end edge 17 and a left and right side edge 18, 18 at the upper end side and the left and right end sides of the vertical substrate 15 having an insertion opening 16 into which the suction opening 12 is inserted at the center, respectively. It is formed integrally so that it looks like
17 are provided with holes 19... Into which the hooking projections 9 are fitted, and the vertical board 15 and the left and right side edges 18, 18 are provided with a turbo-type exhaust fan 10. A hole 20 for inserting a tightening bolt to be mounted on the device is drilled.

Therefore, the tightening bolt 20 allows the turbo-type exhaust 10
The operator lifts the exhaust fan mounting casing 14 on which is mounted, and hooks the holes 19... Opened in the upper end edge 17 on the projections 9... The suction port 12 is pressed into contact with the dust suction port 6 via the packing 7 by the weight of the exhaust fan 10, and the exhaust chamber 2 and the turbo-type exhaust fan 10 are connected in a communicating manner, so that the exhaust air in the exhaust chamber 2 is exhausted. Can be efficiently sucked and discharged without generating pressure loss.
Can be attached to the side wall 3.

[Effects of the Invention] The present invention is configured as described above, and has the following effects.

The turbocharger can be removed only by hanging the upper edge of the exhaust fan mounting casing with the turbo-type exhaust fan detachably attached to the horizontal hook fitting mounted on the side wall of the exhaust chamber so as to hang on the hook projecting member. Is it possible to easily attach the exhaust fan directly to the side wall of the exhaust chamber, or after hooking it, the suction port is pressed against the dust suction port through packing by the weight of the turbo-type exhaust fan, and the exhaust chamber and the turbo-type exhaust fan Can be easily connected, and the exhaust air can be efficiently exhausted without causing a pressure loss as a suction static pressure. In addition, the attachment and detachment of the turbo-type exhaust fan can be easily achieved by one-touch operation.
