Description

TECHNICAL FIELD

[0001] The utility model belongs to powder storage and conveying technical field, concretely relates to a novel powder bin uniform discharging device. BACKGROUND

[0002] The dry powder material has small particle size and light specific gravity, and the pneumatic conveying effect is better in the powder conveying system. The powder bin is a common device in the powder pneumatic conveying, and the powder is injected into the powder bin through the top powder inlet by dumping or through the side powder inlet by pneumatic conveying. Ideally, the powder should be uniformly and stably discharged from the bottom outlet of the powder bin. However, for the powder with high viscosity, abnormal conditions such as center flow and channel flow are easily generated, which significantly reduces the uniformity of the powder discharge, and even the bridging phenomenon occurs, which causes the powder to be completely unable to flow out. To avoid the above abnormal conditions, compressed air or mechanical stirring is usually used to uniformly discharge or loosen the powder in the bin.

[0003] The traditional compressed air uniform discharging device is distributed on the wall surface of the powder bin cone section. When the powder bin is large, the uniform discharging effect on the powder in the central part of the powder bin is poor. Moreover, since the compressed air outlet is directed upward, the powder is easily blocked in the air outlet. To solve this problem, a bin wall vibrator is usually installed to make the powder around the bin wall fall down by vibrating the bin wall. The bin wall vibrator has good effect when used on the flat plate wall, but has poor effect when used on the conical wall. The powder with high viscosity is easily subjected to center flow, channel flow, and other conditions that are not conducive to discharging.

[0004] The patent publication CN205151079U discloses a powder bin, which vibrates the powder in the powder bin by setting a vibrating plate inside the powder bin, and ensures the flow of the powder by setting a screw at the position of the discharge outlet. However, the vibrating plate is set inside the powder bin, and the vibration effect on the powder at the middle position of the powder bin is poor. When the powder reaches the discharge outlet, it is not well dispersed, which results in low flowability of the powder at the discharge outlet. The motor needs to transmit greater force to the screw to complete the powder discharge.

[0005] The patent publication CN116986152A discloses an auxiliary discharging device for a powder bin, which realizes the stirring of the powder in the powder bin by setting a first stirring assembly and a second stirring assembly, and ensures the smoothness of the powder flow. However, the device has relatively complex structure and high purchase cost, which is not conducive to small and micro enterprises to save production cost.

[0006] To solve the above problems, a novel powder bin uniform discharging device is proposed. UTILITY MODEL CONTENTS
