Fire control draught fan supercharging device

Abstract

The invention discloses a fire control draught fan supercharging device which comprises a fire control draught fan, equal altitude blocks and a supercharging cover. A supporting frame is arranged at the lower end of a motor in the fire control draught fan, first connecting flanges are arranged at the two ends, a base plate is arranged at the lower end, the multiple equal altitude blocks are arranged at the lower end of the base plate, the air outlet end of the fire control draught fan is connected with the supercharging cover, the supercharging cover is provided with a conic supercharging taper pipe, the large diameter end of the supercharging taper pipe is provided with a flange, the supercharging taper pipe is internally provided with a taper hole, and the large diameter of the taper hole is communicated with an air outlet of the fire control draught fan in a butt joint manner. By means of the supercharging cover, flowing air output by the fire control draught fan can be compressed,supercharged and output, the air amount lift and kinetic energy of the fire control draught fan are greatly increased, and the quick cooling effect and the smoke discharging efficiency are improved.

Description

Technical field [0001] The invention relates to the technical field of fire-fighting devices, in particular to a fire-fighting fan booster device. Background technique [0002] After the fire, the indoor dense smoke and toxic odors are slowly dissipating, which brings considerable inconvenience to the search and cleaning work of firefighters after the disaster. Generally, high-power fire-fighting fans are used for ventilation. However, the wind pressure of conventional fire-fighting fans is determined by the motor power of the fan. While determining the size and range of the air volume, a fixed fan can only exert its inherent air volume and range, and to a large extent cannot enable the fire fan to exert greater efficiency and range. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a fire-fighting fan booster device, including a fire-fighting fan, a contour block, and a booster cove...

Problems solved by technology

[0002] After the fire, the indoor thick smoke and toxic smell are released slowly, which brings considerable inconvenience to the search and cleaning work of firefighters after the disaster. Generally, high-power fire-fighting fans are used for ventilation. However, the wind pressure of conventional fire-fighting fans is determined by the power of the motor equipped with the fan. To determine the size and range of the air volume, the fixed fan can only exert the inherent air volume and range, and cannot make the fire-fighting fan exert greater efficiency and range to a large extent.
