An air inlet pipe is connected on the powder feeding pipe. A damper is installed on the air inlet pipe. The utility model has the advantages that the structure is simple, the installation and the use are convenient, the work efficiency is improved, the normal delivery of powder materials is ensured, the wastage of the powder materials is reduced, the cost is low, the production efficiency is improved and the spiral feeder can be widely popularized and the use.
Description
Technical field
The utility model relates generally to a kind of calcium carbonate powder Fabricating machinery field, relates in particular to a kind of feed screw.
Background technology
In the calcium carbonate course of processing, need to carry out the grinding operation, in operating process,, do not utilize conveying owing to powdery too much causes being squeezed into piece, influenced production efficiency, overlong time is not also carried, and then can cause the waste of powder, for addressing this problem, existing technology overcomes by ventilating, but existing ventilator tube equipment mostly is to be provided with air door on ventilator tube, though this structure can address the above problem, but its air door is fixed, can't regulate, when excessive or powder was very few at wind-force, powder was stressed excessive, cause its motion random, can overflow during discharging, cause the waste of powder, influence productivity effect.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of feed screw to be provided, and is simple in structure, easy to install, and ventilation inlet place wind-force is adjustable, has improved work efficiency, guaranteed the normal conveying of powder, and cost is low.
The utility model is achieved through the following technical solutions:
A kind of feed screw includes hopper, the powder feeding spiral tube, and the feed opening of described powder feeding spiral tube is connected with powder feeding pipe outward, is connected with blast pipe on the described powder feeding pipe, on the described blast pipe air door is installed.
The utility model is carried powder by described powder feeding spiral tube, and it is simple to operate, can not be subjected to the influence of wind-force, has improved work efficiency, and cost is low, has improved productivity effect.
The utility model has the advantages that:
The utility model is simple in structure, easy to install, has improved work efficiency, has guaranteed the normal conveying of powder, has reduced the waste of powder, and cost is low, has improved productivity effect, can promote the use of.
Description of drawings
Fig. 1 is the utility model structural representation.
