Abstract
The invention relates to a stirring device for a polymerization kettle, and belongs to the mechanical stirring field. The stirring device comprises a stirring shaft and a stirring paddle; the stirring shaft is of an inner-outer dual-layer hollow structure, and an independent cooling water inlet channel and an independent cooling water outlet channel are formed; the stirring paddle is of a hollow structure, and flow guiding channels are formed in the stirring paddle; a cooling water inlet channel and a cooling water outlet channel are formed between the stirring paddle and the stirring shaft. According to the stirring device of the polymerization kettle, heat generated in the polymerization process is taken away through circulating flow of cooling water in the polymerization kettle, uniform cooling of materials in the polymerization kettle can be effectively achieved, therefore, the polymerization process is kept at the temperature required by a technology, and the technological stability and the product quality are improved.
Description
technical field:
The present invention relates to mechanical stirring field, be specifically related to a kind of agitation equipment of polymerization vessel.
background technology:
Polyvinyl chloride (PVC) is stuck with paste resin and is widely used in the industries such as simulated leather, wall paper, gloves, flame-retardant conveyor belt, toy.Because polymerization process can discharge a large amount of heats, this heat, as taken away not in time, can make temperature of charge raise too fast, thus bring destruction.Due to the increase of PVC paste resin demand amount, the capacity requirement of polymeric kettle also strengthens thereupon, and the heat that jumbo polymeric kettle produces in material polymerization process also increases thereupon, and therefore, the cooling performance of the heat radiation cooling device of polymeric kettle also needs to improve.
summary of the invention:
The object of the invention is the problem producing a large amount of heat of polymerization in order to solve Large Copacity polymeric kettle in the course of the polymerization process, and provide a kind of from internal heat dissipating, realize the whipping appts of material Homogeneous cooling in polymeric kettle.
The object of the invention is to be achieved through the following technical solutions: this agitation equipment of polymerization vessel, comprise stir shaft, stirring rake, described stir shaft is inside and outside double layer hollow structure, form the autonomous channel that water coolant enters and goes out, described stirring rake is hollow structure and inside arranges flow-guiding channel, arrange water coolant between described stirring rake and stir shaft into and out of passage, described stir shaft is provided with the water coolant import and export be connected with external pipe.Further, sleeve is socketed with outside the cooling water intakeoutfall of described stir shaft, described sleeve is provided with entrance of cooling water and cooling water outlet, and forms water coolant into and out of passage between the cooling water intakeoutfall of described stir shaft lower end, described sleeve and described stir shaft are tightly connected.
Preferably, accumulate in stir shaft place in order to avoid material and increase the resistance of stirring, described stirring rake arranges one or more through hole perpendicular to stir shaft axis.
Preferably, in order to make cooling performance better excellent, described stirring rake has more than one chamber.
Compared with prior art, usefulness of the present invention is: by stir shaft and stirring rake are designed to an inner cooling system, Homogeneous cooling is carried out from inside to material, good cooling results, make the temperature in polymeric kettle maintain temperature required for technique, thus ensure that stability and the quality product of production technique.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is stirring rake partial schematic diagram.
In figure: 1, stir shaft, 101, outer stirring central siphon, 102, central tube, 103, upper spindle nose, 104, lower spindle nose, 105, entrance of cooling water, 106, cooling water outlet, 107, sleeve, 2, stirring rake, 201, flow-guiding channel, 202, through hole, 203, dividing plate.
embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
According to Fig. 1, a kind of agitation equipment of polymerization vessel shown in 2, comprise stir shaft 1, stirring rake 2, described stir shaft 1 is by outer stirring central siphon 101, central tube 102 forms, thereon, be installed with spindle nose 103 and lower spindle nose 104 respectively down, one end of described central tube 102 and described outer stirring central siphon 101 are separated by and are fixedly connected in described outer stirring central siphon 101 autonomous channel forming inside and outside double-deck water coolant and enter and go out, the other end of described central tube 102 is fixedly connected on lower spindle nose 104 together with described outer stirring central siphon 101, described outer stirring central siphon 101 is fixedly connected with described upper spindle nose 103, entrance of cooling water and outlet are offered in described outer stirring central siphon 101 one end, cooling water outlet is offered in described central tube 102 one end, the tube wall of described outer stirring central siphon 101 is at least offered two holes be communicated with described stirring rake 2, to keep the water coolant in stirring rake 2 and stir shaft 1 to circulate, described stirring rake 2 is for hollow structure and inside arranges dividing plate 203 forms flow-guiding channel 201.
Sleeve 107 is socketed with outside the cooling water intakeoutfall of described stir shaft 1, described sleeve 107 is provided with entrance of cooling water 105 and cooling water outlet 106, and form water coolant into and out of passage between the cooling water intakeoutfall of described stir shaft 1 lower end, described sleeve 107 is tightly connected with described stir shaft 1.
Another preferred embodiment, difference is that described stirring rake 2 arranges one or more through hole 202 perpendicular to stir shaft axis, deposits at stir shaft place to prevent material.
Another preferred embodiment, difference is that described stirring rake 2 has more than one chamber, to increase cooling performance and temperature homogeneity.
Embodiment is as follows: the cooling operation scheme of stirring system is that water coolant flows into from entrance of cooling water 105 via certain dynamic action, the sandwich passage stirring central siphon 101 and central tube 102 and formed is entered through sleeve 107, then stirring rake 2 is flowed into by the hole of stirring on central siphon 101 tube wall, after water coolant flows into stirring rake 2, due to the effect of flow-guiding channel 201, water coolant can be uniformly distributed in whole stirring rake 2, then the water coolant in stirring rake 2 flows into central tube 102 by the hole of stirring central siphon 101 tube wall again, eventually pass sleeve 107 to be discharged by cooling water outlet 106.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
