Problems solved by technology

[0002] In the process of chemical production, the feeding device of powdery materials often has the following failures during the operation of the system: when encountering large particles or compacted powder blocks, the impeller is prone to be stuck, causing the device to stop due to failure and affecting the continuous operation of the system ; The shaft end of the rotating shaft of the powder feeding device is poorly sealed. When the system is running, a certain amount of gas will enter the shell of the powder feeding device, causing powder materials to escape from the shaft end, etc.

Embodiment 1

[0017] as attached figure 1 As shown: the powder material metering and feeding device of the present invention includes a housing 1, the housing is provided with an anti-blocking baffle 2, and the upper right of the housing is provided with a motor 3, and the motor is equipped with a frequency conversion The device 4 and the forward and reverse switching device 5, the motor linkage reducer 6, the reducer drives the chain to drive the rotating shaft 7, and the rotating shaft is equipped with an impeller 8.

Embodiment 2

[0019] In the metering and feeding device for powdery materials, the rotating shaft includes smooth mirror end caps 9 at both ends, and the smooth mirror end caps are equipped with an air inlet pipe 10, and the air inlet pipe is connected to a compressed air cylinder 12, and the Compress the air to prevent the powder from entering the shaft gap, ensure continuous operation without being affected by the powder, and enhance the service life. A spring 11 is installed on the outside of the smooth mirror end cover. In this way, the problem of poor sealing of the shaft end and the leakage of powder is solved.

[0020] The metering and feeding device for powdery materials has a pressure gauge 13 and a regulating valve 14 on the air inlet pipe.

Abstract

The invention provides a powdery material metering and feeding device. In the chemical production process, a powdery material feeding device has the problems that an impeller of the device is usually deadly blocked in the running process of a system, so that the device is stopped by failure, the sealing property of a shaft end of a rotating shaft is poor, and the like. The powdery material metering and feeding device comprises a shell (1) which is internally provided with an anti-blocking baffle (2); a motor is arranged above the shell at the right side; the motor is provided with a frequency converter (4) and a positive and negative rotation switching device (5); the motor is linked with a speed reducer (6); the speed reducer is used for driving a rotating shaft (7) by driving a chain; and the rotating shaft is provided with an impeller (8). The powdery material metering and feeding device is used for feeding during chemical production.

Description

technical field [0001] The invention relates to a chemical equipment, in particular to a powder material metering and feeding device. Background technique [0002] In the process of chemical production, the feeding device of powdery materials often has the following failures during the operation of the system: when encountering large particles or compacted powder blocks, the impeller is prone to be stuck, causing the device to stop due to failure and affecting the continuous operation of the system ; The shaft end of the rotating shaft of the powder feeding device is poorly sealed. When the system is running, a certain amount of gas will enter the shell of the powder feeding device, causing powder materials to escape from the shaft end. Contents of the invention [0003] The purpose of the present invention is to provide a metering and feeding device for powdery materials in view of the above existing problems, which can improve the anti-jamming ability and sealing per...
