The negative pressure air current feeding device solves the technical problems in the prior art that the powder or grain transfer efficiency is not high, powder is accumulated and jammed, and the like, and the negative pressure air current transfer feeding device is characterized in that the transfer efficiency is high, the system can not be plugged easily, and the service life is long.

Description

Negative-pressure air-flow is carried charging equipment
[technical field]
The utility model relates to a kind of pharmaceutical machine, particularly be a kind of be used to carry loose powdery, charging equipment of granular material.
[background technology]
At present, various both at home and abroad to the device structure form of powder conveying, but to less than 0.4 micron, easily the moisture absorption, light specific gravity, the powder conveying of easily waving still are that problem is many.Such as more popular in the market vacuum feeder the traditional Chinese medicine powder that spray drying obtained with regard to being arranged, following problem is difficult to solve.Problem be powder in course of conveying because solid-gas ratio (content of powder and air than) can not finely regulate, powder conveying efficient is not high, the material loading weak effect.Another one subject matter is that the filter efficiency of dust collection is low, the powder that adheres on its filter is to adopt compressed-air actuated pulse backblowing method to remove, and some feeders adopts cylinder cycle motion to pat cloth bag to make and fall back in the barrel attached to accumulated powder on the cloth bag in the material loading, the shortcoming of its existence: one, cylinder cycle motion beating cloth bag frequency is low, efficient is not high, make the cloth bag cracky in the cloth bag process long-term the beating, and cloth bag can be because pat unbalance stress, local accumulated powder can not be come off, and be to produce continuously to make troubles; Two, pressurized air blowback meeting descends the pressurized air pressure when blowback that has moisture rapidly, cause moisture content to condense into little water droplet and adhere on the filter, water droplet is tied more and more in long-term blowback, powder is made moist dissolve, and then the shutoff filter, force the material loading process to be ended.
[summary of the invention]
In view of the problem that present known technology exists, it is effective that the technical problems to be solved in the utility model provides a kind of material loading, and the negative-pressure air-flow that the filter efficiency of dust collection is high is carried charging equipment.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
A kind of negative-pressure air-flow is carried charging equipment, comprise the charging basket I and the charging basket II that communicate, be provided with hollow shaft and spice oar in the described charging basket I, described charging basket II connects vaccum-pumping equipment, be provided with filter in the described charging basket II, the discharging opening place of described charging basket II is provided with discharging device, it is characterized in that: be provided with the scalable air distributing device in the described charging basket I, in order to regulate the solid-gas ratio of powder and air.Described scalable air distributing device comprises the core that is mixed that is installed on described hollow shaft lower end, and the described core that is mixed is positioned at described charging basket I discharging opening, and the gap that is mixed between core and the charging basket I discharging opening can be regulated, and the described core that is mixed is provided with the aperture that communicates with ambient atmosphere.Be provided with the high frequency oscillation filtering installation in the described charging basket II, described high frequency oscillation filtering installation comprises titanium rod frame and the oscillator and the described filter that are installed on the titanium rod frame.Described discharging device is the batch (-type) discharging device, and described discharging device comprises bin gate and rotary cylinder, and described bin gate blocks the discharging opening of described charging basket II, and described bin gate is driven by rotary cylinder and swings back and forth.
The gap that is mixed between core and the charging basket I discharging opening that is provided with in the utility model charging basket I can be regulated, regulate this gap and be equivalent to regulate the interior load of charging basket I, and the aperture that communicates with ambient atmosphere that the core that is mixed is provided with, it is a unmodified from the atmosphere amount of air drawn under negative pressure, (content of powder and air than) can be able to fine adjusting to powder because solid-gas ratio in course of conveying thus, when adjusting is mixed core and charging basket I gap when forming best solid-gas ratio, powder conveying efficient will improve greatly, reach best material loading effect; Be provided with the high frequency oscillation filtering installation in the utility model charging basket II, the high-frequency vibration that produces by oscillator will make the powder that sticks to filter surfaces be eliminated rapidly, and filter efficiency of dust collection height improves service life.
