Vacuum charging/discharging device
Technical field
What the present invention relates to is a kind of charging/discharging device, specifically a kind of vacuum charging/discharging device.
Background technology
Device for discharging is in the market applicable to the handling of dry powdery and granule materials, is the device for discharging being applied to the equipment such as grinding machine, dryer, drying tower, feed bin, grain depot; Material due to conveying needs airtight and have in the system of pressure, negative pressure and transmit, more and more higher to the requirement of the sealing air-tightness of discharge gate, air leakage and delivery pressure; Current device for discharging mainly adopts the sealing of flexible sealing and positiver sealing two kinds of forms, and it seals poor air-tightness, air leakage is large, friction force is large, can not do the high airtight sealing charging of continuity vacuum drying apparatus and use.
The rotating shaft tubular type piecing devices of the magnet fluid sealing of my application: the patent No. (2015205970593), it is made up of device for sealing magnetic fluid, rotation tubular axis, fixed tubular axle.Device for sealing magnetic fluid is arranged on and rotates between tubular axis and fixed tubular axle, and device for sealing magnetic fluid is fixed in the convex groove of rotation tubular axis, and fixed tubular axle is fixed on the outside of device for sealing magnetic fluid, and there is flange one end of rotation tubular axis, fixed tubular axle.The rotating shaft tubular type piecing devices of magnet fluid sealing are easy to use, on the rotating pipe that the flange rotating tubular axis one end is used on connecting device, on the restrained line that the flange of fixed tubular axle one end is used on connecting device, just can play the effect of the pipeline of seal rotary, save labor, good sealing effect, maintenance also facilitates.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcoming existing installation existence, on the basis of rotating shaft tubular type piecing devices (patent No. 2015205970593) patent of my magnet fluid sealing, do further improvement perfect, a kind of vacuum charging/discharging device is provided, be connected to by its flange tap on equipment and just can play sealing function, material can round-the-clock turnover vacuum dryer.
In order to arrive above-mentioned purpose, the present invention is realized by following technical proposals: a kind of vacuum charging/discharging device is made up of sealing arrangement, flange tap, delivery duct, device for discharging, feed arrangement.
Described delivery duct is straight tube, or bend pipe.
One end of described delivery duct is connected to device for discharging, and the other end is connected to flange tap.
Described delivery duct and device for discharging are connected to one.
Described delivery duct and flange tap are by sealing arrangement fixed seal connection.
Described sealing arrangement is device for sealing magnetic fluid, or dynamic sealing device.
One end of described device for discharging is connected to delivery duct, and the other end is connected to feed arrangement.
Described feed arrangement and device for discharging are connected to one.
Described device for discharging is discharge gate, or air sealer, or wind stopping device.
The present invention has following beneficial effect compared with existing charging/discharging device: a kind of vacuum charging/discharging device is easy to use, is connected to by its flange tap on vacuum dryer and just can plays sealing function, and material can round-the-clock turnover vacuum dryer.Starting device for discharging just can seal rotary input and output material, saves labor, good sealing effect, and maintenance also facilitates.Vacuum charging/discharging device can adjust according to the operation pressure of vacuum dryer, and external condition restriction is few, practical, applied range.
