Description

The vacuum-packed blast resistance construction of gas-phase silica
The utility model relates to a kind of blast resistance construction, especially gas-phase silica progress are vacuum-packed anti-for technical field Quick-fried structure.
Background technique gas-phase silica is the white carbon black produced using gas phase process, and final finished is superfinishing fine powder material. In gas-phase silica production process, the finished product gas-phase silica produced generallys use vacuum packing machine and is packed.Packaging The general structure of structure is one vacuum buffer tank of connection between vacuum pump and packing machine.The packaging bag of gas-phase silica is ox Mulberry paper is made, and when being vacuum-packed, sack easily causes rupture in expansion process.Once packaging bag ruptures, i.e., Just in the case where vacuum pump emergency shutdown, still there is a large amount of negative pressure in surge tank, be rapidly evacuated to gas-phase silica powder Vacuum buffer tank causes stifled tank;And remaining gas-phase silica can be pumped down in vacuum buffer tank and connecting tube after booting next time Vacuum pump causes vacuum pump increased wear, ultimately causes damage and scraps.
" a kind of white carbon black vacuum packing machine device for recovering powder " patent (Shen disclosed in Chinese patent CN202555576U Please number: 201220222252.5), including Venturi tube, Venturi tube one end is air intake, and the other end is dust outlet;Institute It states venturi throat and is provided with injector spray tip, throat upper end is provided with dust suction inlet, and throat lower end is provided with and dust The corresponding slag-drip opening of suction inlet.This patent is disadvantageous in that: can remove the white carbon black in vacuum packing machine, but can not Prevention white carbon black powder enters vacuum buffer tank in quick-fried bag and connecting tube causes vacuum pump to wear;By the white carbon black in packing machine It siphons away and is discharged into eluting column, cause white carbon black when quick-fried bag in packing machine to be wasted, cause damages.
Summary of the invention the purpose of this utility model seeks to provide a kind of vacuum-packed blast resistance construction of gas-phase silica, Prevention white carbon black powder enters vacuum buffer tank in quick-fried bag and connecting tube causes vacuum pump to wear, and is scattered when rationally recycling quick-fried bag White carbon black out, save the cost.
In order to achieve the above object, the vacuum-packed blast resistance construction of gas-phase silica provided by the utility model is in addition to having Outside storage bin, control valve, packing machine, vacuum buffer tank and vacuum pump, also there is filter and recovery pump, wherein control valve has It is multiple;Storage bin is connect by control valve with packing machine;Storage bin, packing machine, filter, vacuum buffer tank and vacuum pump are according to suitable Sequence is connected by pipeline;There is an air inlet in filter wall, air inlet is connect by control valve with packing machine;Filter top On have a venthole, venthole is connect by control valve with vacuum buffer tank;Filter lower part is cone, and conical bottom end has One discharge hole, discharge hole are connected to storage bin top by control valve;Recovery pump is placed in filter lower part discharge hole and storing On pipeline between storehouse.
In addition, filter is a kind of device on pumped (conveying) medium pipeline, it is typically mounted on control valve, pressure reducing valve, relief valve Or on Valve for keeping constant water level.When filter works, water to be filtered or gas are entered by import, after strainer, are entered by outlet Required pipeline enters next process, and the granule foreign in water or in gas is trapped within interior.Recovery pump is one Kind impeller pump drives liquid at high speed revolution by impeller and mechanical energy is passed to conveyed gas or liquid.Vacuum pump is Refer to using machinery, physics, chemically or physically chemical method to the device or equipment for being evacuated and being obtained vacuum by pumping container. Filter, recovery pump and vacuum pump are all prior arts, those skilled in the art can select corresponding model be attached and Control.
When the utility model is used, the control valve between storage bin and packing machine is opened by the gas phase hard charcoal in storage bin It is black to be added in packing machine, turn off the control valve between storage bin and packing machine, open packing machine and filter, filter with Valve between vacuum buffer tank, opens vacuum pump, and the air in packing machine in gas-phase silica was passed sequentially through through piping Filter, vacuum buffer tank and vacuum pump and be extracted, complete vacuum packaging;When vacuum packaging, packaging bag ruptures, in packing machine A part of gas-phase silica filter entered by pipeline be under negative pressure blocked in strainer, gas-phase silica will not be into Enter in vacuum buffer tank and vacuum pump and associated conduit;Close the control valve between packing machine and filter, open discharge hole with Control valve between storage bin opens recovery pump, the gas-phase silica in filter in strainer is extracted and is added by pipeline Enter storage bin.
The vacuum-packed blast resistance construction of gas-phase silica provided by the utility model has the effect of positive: in addition to having storage Outside feed bin, control valve, packing machine, vacuum buffer tank and vacuum pump, also there is filter and recovery pump, structure is simple;Work as vacuum Packaging bag ruptures when packaging, and a part of gas-phase silica in packing machine enters filter by pipeline under negative pressure and is blocked In strainer, gas-phase silica will not enter in vacuum buffer tank and vacuum pump and associated conduit, can prevent white carbon black powder Enter vacuum buffer tank in quick-fried bag and connecting tube causes vacuum pump to wear;It needs to recycle quick-fried bag and enters white in filter When carbon black powder, the control valve between packing machine and filter is closed, opens the control valve between discharge hole and storage bin, is opened Gas-phase silica in filter in strainer is extracted and storage bin is added by pipeline, avoids this partial gas phase by recovery pump White carbon black slatterns, save the cost, is suitable for gas-phase silica and packs.
Detailed description of the invention the utility model will be further described in conjunction with attached drawing, please refer to attached drawing:
