Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical production equipment, in particular to a polymerization kettle with a wall coating system. Background Art
[0002] At present, the polymerization kettle wall coating system used at home and abroad has problems such as uneven coating of the polymerization kettle head, missing coating of the inner wall of the upper head, insufficient and incomplete coating, dead angle at the connection between the internal cooling baffle and the upper head of the kettle, and poor coating effect. In addition, during daily intermittent production, the upper head of the polymerization kettle is prone to self-aggregation of sticky materials, resulting in a decrease in the stable production capacity of the polymerization kettle. With the current polymerization kettle wall coating system, when the average number of kettles is 200, the upper head self-aggregation is serious, and the polymerization kettle needs to be high-pressure cleaned, resulting in a decrease in the continuous and stable production capacity of the polymerization kettle. Utility Model Content
[0003] The utility model provides a polymerization kettle with a wall coating system, which solves the problems of uneven and incomplete spraying of anti-sticking agent when coating the walls of the polymerization kettle and the kettle top condenser, failure to fully cover the heads of the polymerization kettle and the kettle top condenser, the connection between the internal cooling baffle and the kettle head, and the cylinder wall, serious self-agglomeration of the polymerization kettle, and inability to produce continuously and stably.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A polymerizer with a wall coating system, comprising:
[0006] A polymerization kettle, wherein a stirring paddle is provided in the polymerization kettle;
[0007] A main anti-sticking agent pipeline is provided with a first delivery pipeline, a second delivery pipeline and a third delivery pipeline. The first delivery pipeline and the third delivery pipeline are both connected to the polymerization kettle. The end of the first delivery pipeline is connected to a wall coating agent nozzle. One end of the second delivery pipeline is provided with a kettle top condenser and a wall coating agent nozzle. The wall coating agent nozzle is a hollow spherical structure with through holes distributed on the surface. The wall coating agent nozzle is located in the kettle top condenser. The first end of the third delivery pipeline is provided with a wall coating agent nozzle. The main anti-sticking agent pipeline is provided with an on-off valve. The kettle top condenser is provided on the top of the polymerization kettle.
[0008] A flushing water pipeline is provided with two auxiliary flushing pipelines, and the ends of the auxiliary flushing pipelines are provided with wall coating agent nozzles.
[0009] Furthermore, a stirring shaft is provided at the bottom of the polymerization kettle; one end of the stirring shaft is connected to a stirring paddle, and the other end is provided with a reducer.
[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0011] 1. Before the present invention is put into use, the polymerization kettle will self-polymerize severely when the average number of kettles is 200, and the polymerization kettle needs to be cleaned. After the present invention is put into use, the polymerization kettle can be cleaned once every 500 kettles, and the self-polymer in the kettle is less than that of the original system.
[0012] 2. The present invention can spray the anti-sticking agent evenly on the top condenser and any part of the polymerization kettle that comes into contact with the material in all directions without dead angles, thus solving the problem of dead angles caused by inadequate wall coating.
[0013] 3. The wall coating of the present invention is faster, more uniform and more effective, and solves the problem of material self-aggregation seriously affecting the continuous, safe and stable production.
[0014] 4. The present invention solves the problem of inadequate cleaning of the kettle top condenser and the polymerization kettle, and can achieve all-round cleaning without dead angles during cleaning, thereby enhancing the coating effect of the anti-sticking kettle agent.

DETAILED DESCRIPTION
[0018] The present invention will be described in detail below with reference to the accompanying drawings.
[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0020] This embodiment provides a polymerizer with a wall coating system, such as Figure 1 Shown, including:
[0021] A polymerization kettle 1 is provided with a stirring paddle 2;
[0022] The main anti-sticking agent pipeline 3 is provided with a first conveying pipeline 4, a second conveying pipeline 5 and a third conveying pipeline 6. The first conveying pipeline 4 and the third conveying pipeline 6 are both connected to the polymerization kettle 1. The end of the first conveying pipeline 4 is connected to a wall coating agent nozzle 7. One end of the second conveying pipeline 5 is provided with a kettle top condenser 8 and a wall coating agent nozzle 7. The wall coating agent nozzle 7 is in the kettle top condenser 8. The wall coating agent nozzle is a hollow spherical structure with through holes distributed on the surface. The first end of the third conveying pipeline 6 is provided with a wall coating agent nozzle 7. The main anti-sticking agent pipeline 3 is provided with a switch valve 10. The kettle top condenser 8 is arranged on the top of the polymerization kettle 1; wherein, the wall coating agent nozzle 7 is a hollow spherical structure with through holes distributed on the surface, which enables the present invention to achieve all-round and dead-angle-free uniform spraying of the anti-sticking agent on the kettle top condenser 8 and any part in contact with the material in the polymerization kettle 1, thereby solving the problem of dead angles due to inadequate wall coating.
[0023] The flushing water pipe 9 is provided with two auxiliary flushing pipes 14 , and the ends of the auxiliary flushing pipes 14 are provided with wall coating agent nozzles 7 .
[0024] The present invention connects the main anti-sticking agent pipeline 3 of the upper end cap of the polymerization kettle with the flushing water pipeline 9 on the top of the polymerization kettle 1 through a fourth delivery pipeline 15. When the anti-sticking agent is applied to the wall, the valve on the flushing water pipeline 9 is closed, and the valve on the main anti-sticking agent pipeline 3 is opened to apply the anti-sticking agent to the kettle top condenser 8 and the polymerization kettle 1. Compared with the design of the existing anti-sticking agent wall coating system, the wall coating range is larger, and the anti-sticking agent wall adhesion effect is increased. When flushing the polymerization kettle, the valve of the main anti-sticking agent pipeline can be closed, and the kettle top condenser 8 can be cleaned together to ensure that the equipment is clean and the anti-sticking agent wall adhesion effect is achieved.
