Abstract
The utility model discloses a kind of feeding devices of paste resin polymerization reaction kettle, it includes the feeding pipe being vertically arranged, the bottom end of the feeding pipe is connected with reaction kettle top, what is be also connected on the feeding pipe is provided with charging branch pipe, has been bolted plunger valve on the top of the feeding pipe；The utility model has the beneficial effects that the utility model structure is simple, it prevents the foam in reaction kettle from entering in Feed lines while simplifying pipeline, avoids the generation of autohemagglutination plasticizing piece phenomenon, improve the service life of equipment, maintenance number is reduced, working efficiency is improved.
Description
Technical field:
The utility model relates to the polymerization reaction kettle of paste resin more particularly to a kind of paste resin polymerization reaction kettle plus
Expect device.
Background technique:
It is prepared in paste resin technique in seed microsuspending method, polymerization reaction needs raw material vinyl chloride monomer and seed glue
Cream, as shown in Figure 1, the first charge pipe 12 and the second charge pipe 13 are respectively used to chlorination vinyl monomer and seed into reaction kettle 2
Latex is provided with stop valve 14 on the first charge pipe 12 and the second charge pipe 13, in polymerization process, reaction kettle 2
There are foam, foams to carry vinyl chloride monomer secretly, the spool position of stop valve 14 be easily accessible, since vinyl chloride monomer has not at top
The characteristics of stablizing easy autohemagglutination, autohemagglutination generates plasticizing piece in the spool of stop valve 14, seal 14 Caton of stop valve can not normally,
Cause frequently to overhaul stop valve 14, the repair time is long, costly, and working efficiency is low.
Utility model content:
The purpose of this utility model is to provide a kind of feeding devices of paste resin polymerization reaction kettle.
The utility model is implemented by following technical solution: a kind of feeding device of paste resin polymerization reaction kettle comprising
The bottom end of the feeding pipe being vertically arranged, the feeding pipe is connected with reaction kettle top, also connects on the feeding pipe
Logical is provided with charging branch pipe, has been bolted plunger valve on the top of the feeding pipe, the piston rod of the plunger valve is perpendicular
Straight setting, the bottom end of the piston rod are fixedly connected with the piston by universal joint, and the lower shape of the piston is reacted with described
The shape at kettle top end is identical, and the bottom end that the piston is able to enter the feeding pipe is in contact with the reaction kettle.
Further, the plunger valve includes the main valve pipe being vertically arranged and the side with main valve pipe vertical connection setting
Valve pipe is provided with the piston rod in the main valve pipe, and the piston rod is connect with the top screw-driven of the main valve pipe, institute
The top for stating piston rod is fixedly connected with turn handwheel.
Further, sealing ring, the feeding pipe and the plunger valve are installed on the periphery of the piston
Sealing ring is installed on joint face.
The utility model has the beneficial effects that the utility model structure is simple, prevented in reaction kettle while simplifying pipeline
Foam enter in Feed lines, avoid the generation of autohemagglutination plasticizing piece phenomenon, improve the service life of equipment, reduce maintenance time
Number improves working efficiency.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model prior art；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the part A enlarged diagram of Fig. 2；
In figure, reaction kettle 2, charging branch pipe 3, plunger valve 4, piston rod 5, piston 6, main valve pipe 7, side valve pipe 8, turn handwheel
9, sealing ring 10, sealing ring 11.
Specific embodiment:
A kind of feeding device of paste resin polymerization reaction kettle as shown in Figure 1 to Figure 3 comprising the charging being vertically arranged
The bottom end of general pipeline, the feeding pipe are connected with 2 top of reaction kettle, and what is be also connected on the feeding pipe is provided with charging
Branch pipe 3 has been bolted plunger valve 4 on the top of the feeding pipe, and the piston rod 5 of the plunger valve 4 is vertically arranged, described
The bottom end of piston rod 5 is fixedly connected by universal joint with piston 6, the lower shape of the piston 6 and 2 top of reaction kettle
Shape is identical, and the bottom end that the piston 6 is able to enter the feeding pipe is in contact with the reaction kettle 2；The plunger valve 4
Side valve pipe 8 including the main valve pipe 7 being vertically arranged and with 7 vertical connection of main valve pipe setting, the interior setting of the main valve pipe 7
There is the piston rod 5, the piston rod 5 is connect with the top screw-driven of the main valve pipe 7, and the top of the piston rod 5 is solid
Surely it is connected with turn handwheel 9；Sealing ring 10, the feeding pipe and the plunger are installed on the periphery of the piston 6
Sealing ring 11 is installed on the joint face of valve 4.
Working principle: when work, charging branch pipe 3 is used to add seed latex for adding vinyl chloride monomer, side valve pipe 8,
Turning turn handwheel 9 after charging and being adjacent to piston base at the top of polymeric kettle can stop feeding, and when reaction, be located at reaction kettle
The foam on 2 tops cannot be introduced into pipeline, avoids the generation of autohemagglutination plasticizing piece phenomenon, improves the service life of equipment, subtract
Number is overhauled less, improves working efficiency.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
