Described tank body and shell and tube heat exchanger are provided with thermal insulation layer, prevent calorific loss.
Material is added by opening for feed, by feed valve, enters in tank body, and material passes through progressively motion of vibration, falls step by step, and it is dry that full and uniform absorption microwave is able to precipitation, completes after precipitation is dried and discharges from discharge port by bleeder valve.
Solvent vapo(u)r passes into tubular heat exchange shell side by solvent vapo(u)r pipe, carry out countercurrent flow with the tube side refrigerated water of bottom in and top out, make solvent vapo(u)r condensation liquefaction, vacuum machine is mainly discharged incoagulability air, because chilled water temperature is low, solvent vapo(u)r condensation dividing potential drop is very low, and the gaseous solvent of extracting out with vacuum seldom, it is temporary that condensing solvent flows into the temporary tank of solvent condenses liquid, by operation, can be controlled and be refluxed by valve.
Core of the present utility model is in fully-closed system, to realize the vaporization of microwave heat energy solvent, and gutta-percha glue reclaims solvent condenses in the time of dry entirely, avoids solvent to leak and causes potential safety hazard and solvent loss.
Material turnover vacuum tank is all to adopt feed valve 6 to carry out pressure isolation, a plurality of microwave generators can be arranged by reasonably optimizing in top and the left and right sides at tank body, and because metal wall can total reflection microwave, microwave energy completely heating object absorbs, energy is loss no, also can not leak; Oxygen content under vacuum state is very low, has also stopped inflammable and explosive potential safety hazard.
Vibration hopper is simple in structure, reliable, material has automatic diffusion profile balancing function, also has the function of similar stirring, fluidisation, is particularly conducive to even absorption microwave, promotes the dry precipitation of the organic solvents such as sherwood oil in gutta-percha.
Adopt multi-layer vibration to carry dry, the superiors' material can move from left to right, two layers of material from right to left, the like, finally by bleeder valve, export, throughput direction is determined by the vergence direction of elastic steel sheet.Rationally control the pattern of vibration, can significantly improve efficiency, simultaneously extension device work-ing life.
The utility model adopts continuous fully-closed system, and vacuum, airtight, microwave heating, vibration microwave heat energy precipitation operate and can avoid that solvent leaks, anaerobic vacuum state does not have inflammable and explosive potential safety hazard in vacuum seal system; Although vacuum state does not have transmission of heat by convection, adopt microwave heating, there is the heat effect that penetration performance is good, material inside and outside is whole, then in conjunction with vibration, be so extremely conducive to the even microwave energy absorbing of gutta-percha under the difficult heat transfer condition of vacuum; In airtight system, because metallic walls has reflection function in the face of microwave, energy can loss and finally by required heating thing, absorbed completely, thereby Energy efficiency is very high; The heat exchange of refrigerated water tubulation can realize solvent vapo(u)r condensation and entirely reclaim, for recycling.
Compared with prior art, of the present utility model being also advantageous in that:
Solve serialization precipitation after gutta-percha is resolved and dry technical barrier, there is simple in structure, lower-cost feature, be applicable to industrialization batch production.
