Description

Technical Field

[0001] The utility model belongs to the field of reaction kettles, in particular to an improved styrene decolorizing mixer. Background Art

[0002] Polymerization reactor (also called mixer) is a common industrial equipment, widely used in chemical, pharmaceutical, food, metallurgy and other fields.

[0003] Reactions carried out in polymerization reactors usually involve changes in pressure. Some reactions need to be carried out under high pressure, while others need to be carried out under low pressure. Currently, existing polymerization reactors cannot change the pressure value in the reactor. When the pressure in the reactor does not meet the reaction conditions or when it is desired to add raw materials to the reactor again during a high-pressure reaction, the pressure value in the reactor cannot be changed, resulting in the reaction in the reactor not being able to proceed normally or the problem of being unable to add raw materials to the reactor separately. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model aims to provide an improved styrene decolorizing mixer to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] An improved styrene decolorizing mixer, comprising:

[0007] A reaction tank, the upper end of which is fixedly connected with a stirring mechanism for stirring the material in the reaction tank;

[0008] A feeding assembly, arranged on the reaction tank, for feeding materials into the reaction tank;

[0009] The pressure relief mechanism is arranged on the reaction tank and can relieve or increase the pressure in the reaction tank.

[0010] Furthermore, the pressure relief mechanism comprises a pressure relief tank, a fixing plate and a pressure relief assembly, and the pressure relief tank is connected to the pressure relief assembly via the fixing plate.

[0011] Furthermore, the pressure relief assembly includes an electric push rod, a push plate and a sealing plate, the upper end of the electric push rod is fixedly connected to the push plate, the upper end of the push plate is fixedly connected to the sealing plate, the sealing plate and the inner wall of the pressure relief tank are movably fitted, and the upper end of the electric push rod penetrates the fixed plate and enters the interior of the pressure relief tank.

[0012] Furthermore, the feeding assembly includes a feeding nozzle, a connecting head, a feeding pipe, a flow meter and a feeding valve. The upper end of the feeding nozzle is connected to the feeding pipe through the connecting head, and the flow meter and the feeding valve are arranged on the outer wall of the connecting head.

[0013] Furthermore, the improved styrene mixer also includes:

[0014] A cleaning nozzle, fixedly connected to the upper end of the reaction tank;

[0015] A protective cover, fixedly connected to the upper end of the reaction tank;

[0016] A discharge nozzle, fixedly connected to the bottom end of the reaction tank;

[0017] A connecting pipe, snap-connected to one end of the discharge nozzle;

[0018] The connecting component has one end threadedly connected to the outer wall of the feeding nozzle and the other end movably connected to the pressure relief tank.

[0019] Furthermore, the pressure relief tank includes an observation window, which is arranged on the outer wall of the pressure relief tank, and the material used for the observation window is tempered glass.

[0020] Furthermore, the connection component comprises:

[0021] A connecting flange, wherein the connecting flange is connected to the upper end of the pressure relief tank by bolts;

[0027] Beneficial effects of the utility model:

[0028] The feeding tube is directly connected to the feeding nozzle through a connector, so that the reaction tank can be directly fed with materials. If the pressure in the reaction tank increases during the reaction, resulting in the reaction conditions not being met, or if the pressure in the reaction tank is too high and separate feeding is required during the reaction but the feeding valve cannot be opened, the air pressure in the reaction tank can be drawn into the pressure relief tank for storage through the pressure relief mechanism, thereby reducing the pressure in the reaction tank so that it meets the reaction conditions. The feeding valve can also be easily opened to feed the reaction tank. If the pressure in the reaction tank is too low and the reaction conditions are not met, the air pressure stored in the pressure relief tank will be released into the reaction tank, thereby pressurizing the reaction tank, so as to achieve the function of changing the pressure in the reaction tank according to actual needs.

When the styrene polymerization reaction is completed, the connecting pipe 7 can be connected to the discharge nozzle 6, and then the discharge nozzle 6 can be opened to discharge the polymerized styrene in the reaction tank 1, and then the reaction tank 1 can be cleaned through the cleaning nozzle 3.

[0051] As a preferred embodiment, the pressure relief assembly 93 includes an electric push rod 931, the upper end of which penetrates through the fixing plate 92 and enters the interior of the pressure relief tank 91;

[0052] Furthermore, the electric push rod 931 can penetrate into the interior of the pressure relief tank 91 and extend and retract inside the pressure relief tank 91 .

[0053] As a preferred embodiment, the upper end of the electric push rod 931 is fixedly connected to a push plate 932, and the upper end of the push plate 932 is fixedly connected to a sealing plate 933, and the sealing plate 933 is movably fitted to the inner wall of the pressure relief tank 91;

[0054] Furthermore, when the electric push rod 931 is extended or retracted, it drives the sealing plate 933 to move up and down through the push plate 932, and then the sealing plate 933 can seal when the inner wall of the pressure relief tank 91 moves, so that the air pressure in the reaction tank 1 can be drawn into the pressure relief tank 91.

[0055] As a preferred embodiment, an observation window (911) is provided on the outer wall of the pressure relief tank 91, and the material used for the observation window (911) is tempered glass;

[0056] Furthermore, the gas extraction can be easily observed through the observation window (911), and the tempered glass can better resist pressure.

[0057] As a preferred embodiment, the connection assembly 8 includes a connection flange 81, the connection flange 81 is bolted to the upper end of the pressure relief tank 91, and the upper end of the connection flange 81 is fixedly connected to a pressure relief pipe 82;

[0058] Furthermore, the connecting flange 81 and the pressure relief tank 91 can be sealed when connected, and then they can be easily separated, and then the gas can enter the pressure relief tank 91 through the pressure relief pipe 82.

[0059] As a preferred embodiment, the outer wall of the pressure relief pipe 82 is provided with a movable groove 83, and the outer wall of the movable groove 83 is movably sleeved with a threaded block 84, and the threaded block 84 is threadedly connected to the outer wall of the feeding nozzle 201;

[0061] The working principle of the utility model is as follows:

[0062] First, the device is placed where it needs to work, and then the device is powered on, and then the connector 202 is connected to the feeding nozzle 201 and fixed, and then the feeding valve 205 can be opened to feed the reaction tank 1. During the feeding, the flow meter 204 can be used to observe how much styrene raw material has been added, and then the stirring mechanism 5 will work to stir the styrene in the reaction tank 1. The protective cover 4 can provide protection during the stirring, and when feeding is needed in the middle, the electric push rod 931 will work to drive the push plate 932 and the sealing plate 933 downward. Move, and then the gas pressure in the reaction tank 1 is pumped into the pressure relief tank 91 through the connecting assembly 8.

During extraction, the gas extraction situation can be observed through the observation window 911 on the surface of the pressure relief tank 91, so that the pressure in the reaction tank 1 can be relieved to meet the reaction conditions. Similarly, when the pressure in the reaction tank 1 is too low and the reaction conditions are not met, so that the reaction in the reaction tank 1 cannot proceed normally, the electric push rod 931 is pushed to make the push plate 932 and the sealing plate 933 move upward synchronously, and the gas pressure in the pressure relief tank 91 is pushed into the reaction tank 1 through the connecting component 8, so that the reaction tank 1 is pressurized, so as to realize the function of changing the pressure in the reaction tank 1 according to actual needs;

[0064] The connecting flange 81 can be removed from the pressure relief tank 91.
