Description
Technical field
The utility model relates to a kind of dry powder filling apparatus, particularly relates to the ultra-fine dry powder filling apparatus that dust granules particle diameter is less than 10 microns.
Background technology
At present, existing powder filling equipment is all vacuumize in container, rely on the negative pressure in container that dry powder is sucked in container, air in container is constantly extracted out, and dry powder is constantly inhaled into container, in the process, dry powder in container is easily followed air and is drawn out of, overstock and cause filter core to block the air can not effectively extracted out in container on filter core, affect filling efficiency, and frequent more renew cartridge also have impact on filling efficiency greatly; In addition, in air extraction process, dust granules can enter vacuum apparatus and causes vacuum pump to damage through filter screen, greatly reduces the service life of powder filling equipment.
Summary of the invention
The filter core existed for overcoming ultra-fine dry powder filling apparatus of the prior art easily blocks, affects the defect of filling efficiency, and the utility model provides a kind of ultra-fine dry powder filling apparatus that effectively can solve filter core blocking, improve the filling efficiency of powder filling equipment; Another technical matters that the utility model solves is: the problem reducing powder filling equipment service life in pouring process because returning powder.
The utility model is achieved by the following technical solution: a kind of ultra-fine dry powder filling apparatus, it comprises annular seal space body, seal cover cap, powder inlet pipe, described annular seal space body interior hollow upper end open, the bottom of described annular seal space body is provided with circular hole, described seal cap sealing is arranged on the opening of annular seal space body upper end, described powder inlet pipe is from top to bottom successively through seal cover cap, the cavity of annular seal space body interior and the circular hole of annular seal space body bottom portion also stretch out in annular seal space body exterior, described powder inlet pipe is fixedly connected with seal cover cap, the filter screen stand with some through holes is arranged with in the outside of the powder inlet pipe being positioned at annular seal space Body Lumen, described filter screen stand madial wall arranges nylon leaching net, all leave gap between the hole wall of the bottom circular aperture of described powder inlet pipe outer wall and annular seal space body and between powder inlet pipe outer wall and filter screen stand and be formed as air by-pass passage, the sidewall of described annular seal space body is provided with the aspirating hole communicated with its internal cavities.
When the utility model uses, powder inlet pipe lower end of the present utility model is inserted in the filling exit on container, and make to seal between the filling exit on the utility model and container, vacuum apparatus is bled by the aspirating hole on annular seal space body, air in container is from the air by-pass passage between powder inlet pipe and annular seal space body bottom portion circular hole, be drawn out of after nylon leaching net filters, dry powder is introduced in container by powder inlet pipe by the dry powder storage device be connected with powder inlet pipe, and the dust be drawn out of with air in pumping process is isolated in inside filtering net by the intrinsic nylon leaching net of annular seal space, not easily dry powder is adhered to because nylon leaching net surface is lubricious, therefore segregate dust finally by air by-pass passage again landing enter in container, can not adhere on filter screen and cause filter net jam.
Further scheme is, described filter screen stand is tubular structure, and its upper and lower end face contacts with the sealed bottom of seal cover cap with annular seal space body respectively.
In order to ensure filter screen uniform force, the through hole on described filter screen stand distributes symmetrically on its tube wall, the circular hole of described through hole to be diameter be 2mm-5mm.The quantity of the circular hole on described filter screen stand is preferably 30-50.
In order to effectively prevent dust from entering vacuum apparatus with air, the order number of described nylon leaching net is preferably 4000-5500 order.Particle diameter due to ultra-fine dry powder is about 10 microns, the aperture of the nylon leaching net within the scope of this order number is less than the particle diameter of ultra-fine dry powder, therefore, in vacuum apparatus pumping process, dry powder particle can not enter vacuum apparatus with air, thus ensure that the service life of vacuum apparatus.
Further scheme is, the order number of described nylon leaching net is 5000 orders.
Fall after rise in container for the ease of dust, the gap between the hole wall of the bottom circular aperture of described powder inlet pipe outer wall and annular seal space body is: 1-1.5mm.
For ease of the replacing of filtering net, described seal cover cap and annular seal space body upper end are threaded connection.
The utility model passes through simply and cleverly structure design, the filter core solving powder filling equipment of the prior art existence easily blocks and affects the technical barrier of filling efficiency and the frequent more renew cartridge of needs, in pouring process, nothing returns powder simultaneously, greatly can extend the service life of vacuum apparatus.The utility model structure is simple, easy to use, can be widely used in dry powder filling.
