Description
The utility model belongs to the auxiliary equipment that the investigation of materials field provides particular surroundings to use.
The preparation of new high-tech material need be carried out in vacuum or protective gas; generally to finish by special equipment; Chinese patent CN.2193767 and CN.2232309 disclose the efficient mixer of a kind of vacuum material and a kind of proportioner, and the former is welded by two kinds of cylindrical shells of cylindrical shape length and constitutes the V-arrangement mixing machine together.Wear at its center of gravity line place and to pass through welding one rotating shaft, be contained on the frame, drive with motor, reductor, opening charging aperture on the short cylinder end socket can external feed pipe, and opening the vacuum mouth of pipe on the long cylindrical shell end socket can external vacuum tube, gas purification jar, vavuum pump, motor connect into the vacuum feed system.Owing to adopt in the long and short barrel batch mixing process material, make to produce multi-faceted collision in intersection and efficiently mix because of different potential differences.The latter mixes machine and sealing system for the high vacuum reactor, adopts radial double mechanical seal and can regulate the supporting and the whole system of mixer axle rotation precision.Above-mentioned vacuum mixed ingredients device is all being worked under certain negative pressure, and does not have handle hole, can not use electronic balance to carry out accurate dosing, so only be suitable for field of industrialized production.
The purpose of this utility model provides a kind of vacuum proportioner, and it can solve the artificial accurate dosing problem under vacuum or gas shield environment effectively.
The purpose of this utility model is realized by following technical scheme: this device is mainly by the casing of being with handle hole, magnetic valve with the mechanical pump interlock, diffusion pump and vacuum shutoff valve and metal tubes are formed, there is a peep hole handle hole top in casing front, the casing both sides have air-filled pore and discharge opening respectively, case lid is a Bolt Connection, double density seal sealing, with the casing of handle hole coaxial position in, outer wall all has ring flange, rubber gloves is fixed on the ring flange of cabinet wall, the ring flange thread connection of handle hole seal cover and cabinet exterior, the aperture of bottom half is connected by metal tubes and diffusion pump, the connection in parallel with the aperture of bottom half of one radial hole is arranged, the ring flange thread connection of discharge opening seal cover and casing discharge opening outer wall on the handle hole ring flange of cabinet exterior.Casing adopts stainless-steel sheet to be welded, and respectively there is reinforcement both sides, and handle hole and discharge opening all adopt at cabinet exterior and weld threaded ring flange, and peep hole adopts the lucite sealing, and ring flange connects, the pipe joint welding method.Mechanical pump mainly has been to take out low vacuum effect (5 * 10-2 torr).Diffusion pump mainly is that pumping high vacuum is with (5 * 10
-3More than the torr).Magnetic valve and mechanical pump interlock mainly are to prevent that gas from flowing backwards.Valve on the metal tubes all is vacuum current-carrying valves, and the valve that is connected with air-filled pore connects the inert gas steel cylinder, can make to charge into general gas in the casing when another valve that is connected with air-filled pore and atmosphere connection, subsequently, can open Box Cover.In order not allow the rubber gloves of handle hole be subjected to external and internal pressure, adopted the working method that vacuumizes simultaneously inside and outside the rubber gloves or inflate simultaneously.When casing vacuum reaches requirement, can charge into inert gas, casing is worked under 1 atmospheric pressure, the handle hole seal cover can be taken off like this, and the rubber gloves that connects by handle hole just can carry out " manual operations ".Vacuumizing and charge and discharge gas shift is controlled by valve.Box Cover can be opened with the different instruments that change the outfit (as pony mixer, day equality), so that provide vacuum or gas shield environment for production, the research of different purposes.
The effect advantage that is compared with prior art had is that vacuum that it provides or gaseous environment can put into electronic balance and carry out the operation of craft batching under 1 atmospheric pressure.Double density seal sealing is adopted in the Box Cover sealing, and the seal cover of handle hole and discharge opening all adopts the screw thread end face seal.Can improve its vacuum like this and keep the vacuum time for a long time and easy to operate etc.
