Quantitative conveying system for wood flour

Abstract

The invention relates to a wood flour quantitative conveying system. Including storage bin, feeding bin, inclined screw, separator and Venturi, the storage bin is a rectangular structure, the lower end of the storage bin is open, the inclined screw is installed obliquely at the lower end of the storage bin, and the upper end of the inclined screw The bottom is connected with a flap valve, the separator is installed at the upper end of the storage bin, the separator is located above the lower end of the inclined screw, and the rear end of the Venturi is connected with a blower, and the air inlet of the blower is connected with the upper end of the feed bin through a suction pipe, separating The upper end of the separator is connected with the suction pipe through the smoke exhaust pipe, the side wall of the separator is provided with a feed pipe, the other end of the feed pipe is connected with the lower end of the feed bin, and the inclined screw is controlled by a frequency conversion motor. The invention has a simple structure. By using an inclined screw to convey wood powder and using a frequency conversion motor to control the inclined screw, the conveying amount of wood powder can be accurately controlled; Wind conveying; Venturi is installed at the lower end of the flap valve, so that the powder will no longer block the conveying pipe, reducing the maintenance rate; high safety.

Description

Technical field [0001] The invention relates to a wood powder quantitative conveying system. Background technique [0002] At present, for some wood powder burners on the market, the biggest failure is the wood powder conveying. Many companies use conical bins, which are especially easy to bridge. The wood powder does not go down and the wood powder conveying is interrupted, causing combustion. When the fire is cut off, the conical bottom is likely to cause wood powder to agglomerate, causing difficulty in air delivery and deflagration in the furnace, which often blocks the powder pipe and makes it unusable. In some enterprises, the induced draft fan sucks powder into the combustion chamber. This method can easily damage the fan blades and increase the maintenance rate. Inaccurate or uncontrollable control of wood powder supply and powder air flow, resulting in deflagration and black smoke. Summary of the invention [0003] In view of the above-mentioned defects, the purpose of ...

[0002] At present, for some wood powder burners on the market, the biggest failure lies in the transportation of wood powder. Many companies use conical material boxes, which are especially easy to build bridges. The machine breaks the fire, and the conical bottom is easy to cause the wood powder to agglomerate, resulting in difficulty in air supply and deflagration in the furnace, which often blocks the powder delivery pipe and makes it unusable

In some enterprises, the induced draft fan sucks the powder and sends it into the combustion chamber. This method is likely to cause damage to the fan blades and increase the maintenance rate.
