All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application discloses a polymerization reaction kettle assembly. Referring to fig. 1 and fig. 2, the polymerization reaction kettle assembly includes kettle body 1 and locates the discharge gate 11 of kettle body 1 bottom, terminal surface sets up to the form of closing in under the kettle body 1, it is provided with crane 2 to go up and down in the kettle body 1, the lower terminal surface of crane 2 is provided with cyclic annular gasbag 3, be provided with the gas tube 31 that the free end extends to the kettle body 1 outside on the cyclic annular gasbag 3, be flat disc shape and its periphery wall contradicts with kettle body 1 inner wall after cyclic annular gasbag 3 is full of gas, the outer arc week side of cyclic annular gasbag 3 is provided with the smooth layer, the smooth layer can be the polyurethane coating layer of spraying on cyclic annular gasbag 3 outer wall, also can be for scribbling the lubricant layer on cyclic annular gasbag 3 outer wall, this embodiment is for reducing the influence to polymerization in the kettle body 1, set up the smooth layer into the polyurethane coating layer.
Referring to fig. 1 and 2, a disc 4 which is matched with the hollow part of the bottom surface of the annular air bag 3 in a jogged mode is arranged in the middle of the lower end surface of the lifting frame 2, and the lower side surface of the inner arc of the annular air bag 3 is fixedly connected to the periphery of the arc surface of the disc 4; and be provided with between disc 4 and crane 2 and be used for injecing the limited mechanism of interval between the two, limited mechanism is including installing the elastic component 5 between crane 2 and disc 4, and elastic component 5 establishes to the spring of both ends respectively with disc 4 and crane 2 rigid coupling, can establish to one or be a plurality of that equidistant even array set up along disc 4 axial.
After the arrangement, when polymerized colloid is required to be extruded after polymerization reaction in the kettle body 1 is completed, gas is introduced into the annular air bag 3 through the gas filling pipe 31 to expand the annular air bag 3 until the bottom surface of the annular air bag 3 is flush with the disc 4 and the outer periphery of the arc surface is butted with the inner wall of the kettle body 1, the annular air bag 3 and the disc 4 can stably and uniformly press down the polymerized colloid in the kettle body 1 when the lifting frame 2 is pressed down, the contact areas of the annular air bag 3 and the disc 4 with the polymerized colloid are large, so that the damage to the polymerized colloid is small when the lifting frame is pressed down, and smooth discharge of most of the polymerized colloid in the kettle body 1 is facilitated.
Even when the glue pressing is to the closing-in part of the kettle body 1, because the annular air bag 3 is only arranged between the lifting frame 2 and the disc 4 and the lifting frame 2 and the disc 4 are also provided with the limiting mechanism, when the annular air bag 3 slides to the closing-in part of the kettle body 1, the annular air bag 3 is wholly retracted, the distance between the lifting frame 2 and the disc 4 is enlarged and limited by the limiting mechanism, when the lifting frame 2 is continuously pressed down at the moment, the annular air bag 3 and the disc 4 can still effectively extrude the polymerization colloid in the kettle body 1 with the reduced diameter, thereby the polymerization colloid generated in the kettle body 1 can be completely cleaned as far as possible, the pressure for cleaning the kettle body 1 by subsequent production personnel is greatly reduced, the comprehensive production efficiency is also obviously improved, and the maintenance cost is reduced. When the annular air bag is used for producing alkaline or acid products, the annular air bag 3 is only required to be made of alkali-resistant or acid-resistant rubber correspondingly, and the annular air bag has wide application prospect.
In consideration of the fact that in actual production, even if a smooth polymer colloid is prepared, the phenomenon of wall hanging still exists in the process that the polymer colloid is extruded by the annular air bag. Therefore, as a further optimization, referring to fig. 2 and 3, the upper side of the outer arc of the annular air bag 3 is fixedly connected with the scraping strips 32 arranged along the annular contour thereof, the cross sections of the scraping strips 32 can be rectangular, trapezoidal, triangular, rhombic and the like, and only the tip end thereof is arranged towards the inner wall of the kettle body 1; the up end of cyclic annular gasbag 3 slides and sets up the lower terminal surface at crane 2, is provided with on crane 2 to be used for ordering about disc 4 towards being close to/keeping away from the control mechanism that crane 2 removed.
After setting up like this, when the needs scrape the wall clearance, order about disc 4 through control mechanism and remove towards the direction that is close to crane 2, because cyclic annular gasbag 3 is for being full of the gas state this moment, and crane 2 carries on spacingly to cyclic annular gasbag 3, and the gaseous even gas ring of atmospheric pressure that forms of cyclic annular gasbag 3. When the disk 4 moves towards the direction close to the lifting frame 2, the disk drives the lower side part of the inner arc of the annular air bag 3 to move along with the disk 4, and the upper end surface of the annular air bag 3 is arranged on the lower end surface of the lifting frame 2 in a sliding manner; therefore, the main body of the annular airbag 3 moves from the inner arc side of the annular airbag 3 to the outer arc side of the annular airbag 3 relative to the gas ring, that is, the inner arc lower side portion of the main body of the annular airbag 3 moves from the inner arc lower side portion of the gas ring to the inner arc upper side portion of the gas ring, and the corresponding outer arc upper side portion of the main body of the annular airbag 3 moves from the outer arc upper side portion of the gas ring to the outer arc lower side portion of the gas ring, that is, the scraping strips 32 on the annular airbag 3 move from the outer arc upper side of the gas ring to the outer arc peripheral side or the lower side of the gas ring; make along the strip 32 of scraping that 3 annular profiles of cyclic annular gasbag set up fully contradict on the 1 inside wall of the cauldron body, and then can realize scraping wall, the clearance effect to 1 inner wall of the cauldron body along with the removal of cyclic annular gasbag 3 to atmospheric pressure in the cyclic annular gasbag 3 is big more, scrapes the strip 32 and to scrape that the wall effect is better, the clearance effect is better of the 1 inner wall of the cauldron body.
In a possible embodiment, with reference to fig. 2, the wiper strip 32 is provided in one piece and coaxially with the annular bladder 3, the wiper strip 32 being made of an elastic material, such as an elastic rubber or the like.
