Description

A kind of propeller

Technical field

The utility model relates to paper making equipment technical fields, and in particular to a kind of propeller.

Background technique

Propeller is mainly used for the storages slurry equipment stirring such as stock tank or slurry tower in paper industry, keeps slurry uniform.It is existing Propeller is mainly made of impeller, transmission device, power device and fixed device.Impeller is mounted on main shaft one end, and main shaft passes through Bearing is in the form of two o'clock loaded on bearing bracket stand.Driving pulley is installed on the main shaft other end, remaining each part is assembled into an entirety. Motor drives main shaft rotation by V-belt, and impeller recycles in stock tank with main axis, impeller propelled slurry.But V-belt Cornerite is small, easy to wear.This problem can not be increased since the diameter pulley of propeller is limited by mounting condition, triangle strip length Also it is not easy to lengthen, diameter pulley is difficult to increase and do not solve very well.

In this regard, the Chinese patent of 203021854 U of Publication No. CN discloses a kind of propeller, including main shaft, main shaft two End is connected separately with impeller and actuating unit, and the actuating unit includes cabinet and taper, and taper is logical It crosses bolt to be detachably connected on outside cabinet, rotation is equipped with input shaft and output shaft in cabinet, and input shaft one end, which is equipped with, is located at cabinet Outer vee-pulley, main shaft one end pass through taper and are fixedly and coaxially connected with output shaft, and input shaft is equipped with driving gear, Output shaft is equipped with the driven gear that connection is engaged with driving gear.

But a propeller is only arranged when to the storages slurry equipment stirring such as large-scale stock tank or slurry tower in the device Shortcomings When, the effect which is played is poor, when not being able to satisfy production, uniformly keeps to slurry；Multiple propellers are set simultaneously When, increase cost.
