Description

FAN FOR AGRICULTURAL-LIVESTOCK INDUSTRY SUCH AS VENTILATING FAN, BLAST FAN AND STIRRING FAN}

The present invention relates to a concentrated farm fan (collectively referred to as a farm fan, a livestock fan, a drying fan, a factory fan, etc.), which is installed on a wall or in a building, such as an assembled, disassembled ventilation fan, a blowing fan, and a stirring fan. will be.

Conventionally, this type of concentrated fan (called a ventilation fan) has a structure of assembling at a factory, and this assembled ventilation fan has been shipped using a conveying means such as a track. The general configuration includes a ring-shaped frame (casing) such as a bell mouse, a drum, an impeller rotated by a drive unit (motor), and a guard provided as necessary, on the inner circumferential side (inner side) of the frame. It is an integrated structure that forms a slight gap to install the tip of the impeller. Therefore, the following problems are mentioned.

A) It requires assembly cost and packing cost, and it requires a lot of home area at the time of complicated work, increase of cost and conveyance.

B) In the molding of the frame, a large press machine, a mold, or the like is required, which requires complicated work, increased cost, and a large factory space.

C) Since a small gap is formed on the inner circumferential side of the frame to install the tip of the impeller, improvements such as precision required for molding and assembly, skill required, and difficulty in assembly at the installation site, etc. have.

D) Since the pipe diameter and the pipe diameter of the house material (frame assembly pipe diameter of the house) are separate structures, there is an improvement in that the pipe fixing member and other parts cannot be shared.

E) When suspending a ventilation fan with a hoist such as a rope, there are improvements such as requiring a fastening bracket and damaging the rope by an edge of a component of the ventilation fan. In addition, since it is difficult to secure the standing state of the ventilation fan, labor and experience are required when the rope is hung.

F) The installation of the ventilation fans is standardized. Therefore, it can become difficult in changing a wiring after installation, a change of an installation direction, etc.

G) Since the inflow of air to the impeller and the air ejection from the impeller are suppressed by the frame, free flow is restricted, noise is generated, or loss, pressure loss, etc. in terms of suction, blowing, etc. There are improvements such as being there.

In recent years, the following structure has been proposed as a lightweight and thin ventilation fan (improved ventilation fan). The outline thereof is composed of an annular pipe frame, an impeller support plate provided in the radial direction from the axis of the pipe frame, and a drive unit provided at the center position of the support plate. Therefore, the above-mentioned results can be expected in solving the above-mentioned b), d) and f). However, it can be said that there is room for improvement in terms of a), c), e) and g).

As described above, in the conventional general one-piece structure, there are improvements of a) to b), and improvements of a), c) or e) and g) are also mentioned in the improved ventilation fan.

In view of the above, the present invention intends the following. The intention is listed below.

1. Features on the assembly surface,

(1) In the step of assembling the impeller in the frame, the centering of the impeller is unnecessary, so that it can be delivered as a part and assembled at the installation site, so that the cost of assembling or packing (re) or the resource of the packaging material can be achieved. We try to save.

(2) According to the shape of the impeller, it can be accommodated in a substantially Δ-shaped box package, and the dripping water is expanded, so that the amount of transportation and the cost of transportation can be expected to be reduced.

2. Features in shape and structure,

(1) It is possible to provide a ventilation fan with a hydrodynamically low resistance and rigid pipe structure.

(2) Light weight and solid.

(3) The edge part was eliminated by ensuring the whole curved shape.

(4) The space around the impeller was divided into an annular pipe frame and a substantially Δ-shaped pipe support, and the guard portion was provided so as to surround the impeller over the pipe frame and the pipe support, thereby becoming a simple guard state.

(5) Depending on the situation, the suspension fixing member becomes unnecessary, and it is possible to secure a simple suspension operation and to perform a rapid suspension operation. For example, by cross-crossing (called a wire) using the gap between the pipe frame and the intersection of the pipe support, it is possible to prevent the fall of the wire and to suspend in a stable state. Moreover, since there is no edge part, it can contribute to the improvement of durability of a wire.

(6) Since the linear base portion is provided on the support of the outer peripheral portion of the frame, when the ventilation fan is placed horizontally on the shaft, stable installation can be achieved without falling down as in the prior art.

3. Features on the mounting surface,

(1) There are no restrictions on assembly and installation since the wire extraction direction (direction fixed to the pipe) is various directions.

(2) Moreover, the wiring change after installation can be easily changed in various directions.

(3) If the pipe diameter is the same as that of the house material, a pipe fixing member of a commercially available house material using the base portion of the frame and the support can be used.

(4) There are many suspensions or parts that can be supported. For example, there are eight places.

(5) As a result, the suspension force may be 1/8, and even a structure having a weak strength may have a small force per support material, and thus may be attached or easy to install.

(6) The four arms are suspended by a machine or the like, and can be installed with four other empty ones. Also, they are characterized by stable suspension, stable installation, or easy installation.

(7) Since the intersection of the frame and the support is empty, the wire can be crossed to the wire and the wire does not come off, and as described above, there are features such as stable suspension and stable installation or easy installation. Moreover, since it is a frame made of a pipe material, and a support body (no edge part), the improvement of abrasion resistance, durability, damage resistance, etc. of a wire can be aimed at. In addition, the rounding finish of the edge part becomes unnecessary and is advantageous.

(8) When crosslinking and supporting the house, it is possible to spread out and install the wire horizontally using eight support points as described above, and as described above, stable suspension and stable installation can be achieved. There is a profit.

(9) By making the frame higher than the mounting surface of the support body, it becomes easy to insert and remove the suspension rope in the state which is placed on the ground, and also to make installation work and the like, and to achieve stable suspension and stable installation as described above. There are features such as being able.

4. Performance, characteristics in terms of use,

(1) When using a ventilation fan (used in an open state), there is no need for a conventional frame (bell mouse, drum, etc.), so that the convenience, weight, or cost can be reduced.

(2) By removing the conventional frame, the ventilation fan enables air to flow into the impeller from the impeller outer periphery, thereby increasing the amount of air.

(3) By removing the conventional frame, the ventilation fan eliminates the structure that suppresses the intake (inflow) of air to the impeller or the ejection of air from the impeller, and also generates air because the air flows freely. In addition, there are features such as being able to eliminate the loss of air flow, wind speed, pressure loss and the like.
