Abstract
The utility model provides a metering feeding device of powder materials. In the process of chemical production, the problems that a vane wheel of a feeding device of powder materials are often stuck in the operation process of a system, a machine is shut down due to device failure, or seal performance of a shaft end of a rotating shaft is poor, and the like exist. The metering feeding device comprises a shell body (1). An anti-blocking baffle (2) is arranged in the shell body, a motor (3) is arranged on the upper right portion of the shell body, the motor is provided with a frequency converter (4) and a clockwise and counterclockwise rotation switching device (5), the motor is in linkage with a speed reducer (6), and the speed reducer drives a chain driving rotating shaft (7), and the rotating shaft is provided with a vane wheel (8). The metering feeding device of the powder materials is used for feeding in chemical production.
Description
Technical field
The utility model relates to a kind of chemical industry apparatus, is specifically related to a kind of granular material dosing feeder.
Background technology
In chemical process, the charging gear of granular material is normal in system's operational process, and following fault occurs: run into larger particle or impeller occurs easily during the powder agglomates that hardens stuck, cause plant failure to shut down, affect the continuous operation of system; Shaft end seal to powder device turning cylinder is poor, when system moves, gives in the powder device case and can scurry into a certain amount of gas, causes that granular material is altered etc. outside axle head.
Summary of the invention
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of granular material dosing feeder, can improve metering to anti-sticking ability and the leak tightness of powder device, realizes the accurate-metering of material, feeds reactive system uniformly and stably.
Above-mentioned purpose is achieved through the following technical solutions:
The granular material dosing feeder, comprise housing, be provided with the anti-sticking baffle plate in the described housing, there is motor in described housing upper right side, described motor is equipped with frequency converter and positive/negative rotation switching device, described motor linkage reductor, described reductor drives the chain drive turning cylinder, and described turning cylinder is equipped with impeller.
Described granular material dosing feeder, described turning cylinder comprise the smooth mirror surface end cap at two ends, on the described smooth mirror surface end cap air inlet pipe are housed, and described air inlet pipe connects compressed air cylinder, and spring is equipped with in the described smooth mirror surface end cap outside.
Described granular material dosing feeder has compression indicator and control cock on the described air inlet pipe.
Beneficial effect:
1. the utility model adopts the elasticity anti-sticking baffle plate that tilts to rotation direction at the inlet point place, is equipped with the positive/negative rotation switching device of electric control system, and the plant failure that larger particles or the stuck impeller of powder agglomates that hardens caused when prevention was given powder is continuously shut down.
2. the utility model adopts frequency converter to make the rotor frequency control, regulates powder-feeding amount by control system, passes through adjusting rotary speed, realize that by rotating shaft and impeller accurately the control granular material is to output, satisfy need of production, guarantee the granular material accurate-metering, feed uniformly and stably reactive system.
3. the utility model adopts the turning cylinder axle end sealing device, strengthens shaft end seal, prevents that defeated powder wind from carrying powder and altering outward, loses desulphurization chemical and causes environmental pollution.
4. the utility model guarantees not to be subjected to powder to affect continuous operation by preventing that from the air inlet pipe input compressed-air powder from entering shaft clearance, strengthens service life, and compressed-air actuated input pressure intensity can be regulated by control cock as required.
