Abstract

PURPOSE: A straight air current circulation fan is provided to form entirely even air current by mounting several fans in a greenhouse of 100m. CONSTITUTION: A straight air current circulation fan comprises a fan case(11), a motor fixing member, a wing(13), a guide(14) and a guide fixing part(15). The radial board guide is fixed on the front of a wing on the case of the circulation fan. The motor is fixed on the cylindrical case of the circulation fan. The wing is installed and fixed in the shaft of the motor. The air current is formed at the wing according to the rotation of the motor. The cylindrical case of the circulation fan is fixed on the front of the wing using a spot.

Description

Straight air circulation fan {Ventilation Fan for Linear-Flow}

In the cultivation of greenhouses, the circulation fan is used for proper airflow during the growing season. It is a technology for a circulation fan aiming to form a straight air flow without turbulence in order to reduce the number of fans in the greenhouse of about 100m in length and to form a proper airflow.

In order to create airflow in the greenhouse disconnected from external weather, a fan using an electric motor is used. Air flow is formed by the rotation of the blades, but turbulence occurs and a guide is used as necessary. In general, a fan is the same as using a guide that splits the turbulence for a gentle wind.

In a long greenhouse, it is necessary to form a strong air stream in the straight line to form a circulating vortex in the greenhouse, which can reduce the number of fans installed and achieve the required purpose.

In general, as a guide additionally installed in front of the wing, a specially shaped guide is also developed, which plays a role of lowering pulsation by advancing the airflow by the wing and fixing and reinforcing the case.

On the front part of the wing, the straight plate and the radial plate guide whose angle is important are fixed to form a straight air stream.

Generally, 5 ~ 1m / sec airflow is most suitable for crop cultivation in greenhouse. However, it was not easy to form a uniform air flow throughout the greenhouse with a width of 6 to 10m, a height of 3 to 6m, and a length of about 100.

This straight stream circulation fan can form a uniform air flow as a whole by installing two to three in a 100m long greenhouse. Crop growth conditions by moderate airflow have shown various advantages such as equalization in the vertical direction of air temperature, uniformity of carbon dioxide gas, uniformity of humidity and ease of dilution of harmful gas.

2 is a cross-sectional view of the fan

The motor 12 is fixed to the cylindrical case 11 of the circulation fan, and the vane 13 is fixed to the shaft of the motor. As the motor rotates, the air flow is formed in the wings 13, thereby basically generating turbulence. The straight airflow guide 14 of the invention is fixed to the cylindrical case 11 of the circulation fan with a spot 15 in front of the wing 13.

As shown in the figure, the straight airflow guide 14 has a straight portion 23 and four radial shapes having a predetermined length in the center portion. The central straight portion 23 of the linear airflow guide 14 corresponds to a section corresponding to the center 22 of the blade, in which no airflow occurs.

It is most effective to set the upper and lower angles 21 of the four radial plates of the linear airflow guide 14 to about 95 degrees. The width 24 of the guide plate is equal to the horizontal projection height 25 of the wing.
