Shown in Figure 2, another main improvements of the present utility model are, be provided with kick-off arm 4, be used for after reaction is finished, extrude the material in the kettle 2, the size of kick-off arm 4 and shape need to be complementary with the reaction chamber 23 of kettle 2, guarantee extrusion reaction chamber 23 interior materials effectively, specifically, the pushing block 42 that is used to release material that described kick-off arm 4 has the body of rod 41 and is located at the described body of rod 41 ends, operate for ease of pusher, the length of the described body of rod 41 should be greater than the degree of depth of described reaction chamber 23, and bar head 23 can be set at the other end with respect to pushing block 42, and described bar head 23 can be done the design of handled easily, for example: design has than major diameter, and has the bar head 23 of certain roughness decorative pattern.Be understandable that, for the material in the effective extrusion reaction chamber 23, the shape and size of described pushing block 42 should be complementary with the shape and size of described reaction chamber 23, in general, reaction chamber 23 is cylindrical shape, described pushing block 42 also is cylindrical shape, the equal diameters of the diameter of pushing block 42 and reaction chamber 23; In the present embodiment, flow out from discharge opening 20 for the ease of material, described reaction chamber 23 is provided with and is inverted round table-like bottom 24, correspondingly, described pushing block 42 is located at and is inverted round table-like bottom 43, and the radial dimension of pushing block 42 equates with the radial dimension of reaction chamber 23; What deserves to be mentioned is, because kettle 2 is made for stainless steel, and kick-off arm 4 adopts alloy material (also can be stainless steel) to make, thereby, in the time of in kick-off arm 4 places reaction chamber 23, interference fits or interference fit be necessary for matched in clearance, if then can't enter reaction chamber 23, yet, matched in clearance between kick-off arm 4 and the reaction chamber 23 can make kick-off arm 4 must effectively remove the material that is positioned on reaction chamber 23 walls, and leave defective material.Thereby, preferably, periphery at pushing block 42 offers groove 44, and O shape circle 45 is installed in described groove 44, and described O shape circle 45 adopts rubber to make, and it protrudes from the periphery setting of pushing block 42, has certain compression ratio, thereby in the time of in kick-off arm 4 places reaction chamber 23, O shape circle 45 is subjected to force compresses and is close to reaction chamber 23 walls.As shown in Figure 3, direction towards discharge opening 20 promotes kick-off arm 4, when pushing block 42 contacts with the bottom of reaction chamber 23, stop to promote, at this moment, the material in the reaction chamber 23 is extruded fully, by the coupling design of kick-off arm 4 with reaction chamber 23, and the design of discharge opening 45, effectively the material in the extrusion reaction chamber 23 is avoided the residual of material.
The using method of reactor of the present utility model is as described below: (1), reactor top cover 1 is opened, reaction chamber 23 is cleaned out, with pack into discharge opening 20 and putting in place of plug 5, make the end face of plug 5 concordant with the bottom of reaction chamber 23; (2), ready first solid and/or liquid material are added in the reaction chamber 23, install reactor top cover 1, and guarantee its sealing; (3), install charge pipe 8, vacuum-pumping tube 11 and agitating device 3, and install vavuum pump, vacuum meter (not shown), by seal 6, and shaft mechanical sealing member 7, make charge pipe 8, vacuum-pumping tube 11 and agitating device 3 installation firmly and sealing; (4), open stirring motor, low-speed running is opened vavuum pump, is evacuated to required vacuum, closes vacuum valve 9, stops the vavuum pump operation, checks the vacuum leakproofness of reactor; (5), open vacuum valve 9, rotation rubber cap 10 is let out vacuum to normal pressure, rotates rubber cap 10 sealings again, closes vacuum valve 9; (6), open reinforced ball valve 13, in reaction chamber 23, add second batch materials, close reinforced ball valve 13, the method for (4) vacuumizes and reacts to required time set by step, as also needing to add material, can be by this step repetitive operation; (7), after reaction finishes, let out vacuum, as shown in Figure 3, open reactor top cover 1, open plug 5 then, use kick-off arm 4 that material is extruded fully to normal pressure.(8), can wait to solidify the back film forming and remove,, also reactor top cover 1 and reactor bottom 21 can be unloaded, again with solvent clean or use the cloth scrub for the material that is difficult to remove for remaining in a small amount of material on reaction chamber 23 inwalls.
Compare with existing reactor, reactor of the present utility model has following characteristics:
1, be made by stainless steel owing to kettle, thereby can be used for the system of vacuumizing, vacuum can reach-0.099MPa-0MPa, can be used for the compressive reaction system, and pressure is 0-0.4MPa.
2, be made by transparent material owing to the reactor top cover, thereby the course of reaction in the kettle is high-visible, the danger in the time of can avoiding in course of reaction, having boiling or bubble operation, and help researching and analysing.
3, kettle adopts the stainless steel material through surface finish to be made, the corrosion of energy acid and alkali resistance, organic solvent, when being used to make full-bodied resin system, because full-bodied resin system is weaker than the glass reaction still to the cohesive force of stainless steel cauldron, for example: when being used for make-up room temperature vulcanizable silicone glue, since silica gel to the stainless steel cohesive force a little less than, and can form film on the surface after solidifying, thereby be easy to remove.And, because the utility model is provided with kick-off arm and carries out pusher, the bottom that can guarantee reaction chamber does not have material and sinks to the bottom residual, and the uniformity of assurance reaction system, thereby reactor of the present utility model is applicable to the big reaction system of range of viscosities (extremely almost not having mobile body of paste from conventional low viscosity solution), both compatible conventional low viscosity reactor function can be used for full-bodied reaction system again.
4, reactor top cover of the present utility model and reactor bottom are dismountable being installed on the reactor tank body, when residual when the residue that is difficult to remove is arranged in the reaction chamber, can dismantle the reactor bottom and use kick-off arm effectively to remove residue, dismantle and clean very convenient.
In a word, reactor of the present utility model has both the advantage of existing reactor, and is provided with separable kick-off arm and carries out discharge, can avoid residual material, and is easy to operate, applied widely.
The above only is preferred embodiment of the present utility model, not in order to restriction the utility model, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
