[0002] Chinese patent database discloses a kind of high viscosity polymerization reaction device, publication (announcement) number: CN222131888U, publication (announcement) day:2024.12.10.This kind of high viscosity polymerization reaction device, including high viscosity reactor, discharging machine, circulating pump, feeder and feeding pump, high viscosity reactor bottom discharge port is connected with the feeding port of discharging machine, wherein the screw of discharging machine is inserted into high viscosity reactor inside, the feeding port of discharging machine is connected with the feeding port of circulating pump, the feeding port of high viscosity reactor side near upper end is connected with the discharge port of feeder, circulating pump's discharge port and the feeding port of feeder bottom end are equipped with the circulating pipeline for realizing the overall external circulation of material, feeding screw is arranged in circulating pipeline, to form external reinforcement circulating stirring, the second discharge port of discharging machine is connected with the feeding port of feeding pump, and the discharge port of feeding pump is equipped with discharge pipeline.

[0003] The above technical solution has the following disadvantages: the screw of the discharging machine is inserted into the high viscosity reactor, which realizes the discharging of high viscosity material. However, since the discharging machine is directly connected with the reactor through a flange, if the discharging screw is an equal outer diameter structure, the feeding area of the head of the discharging screw must be smaller than the pipe diameter. Therefore, compared with the large space at the bottom of the reactor, the material guiding capacity of the part of the discharging screw inserted into the reactor is poor. If the blades at the upper end of the discharging screw are conical structures with large size at the top and small size at the bottom, the discharging screw can only be pulled out of or inserted into the reactor during subsequent maintenance and assembly of the discharging screw. Therefore, it is not convenient for assembly and maintenance work. UTILITY MODEL CONTENT

[0004] The embodiment of the present application provides a vertical high viscosity polymerization reaction device to solve the technical problem of inconvenient maintenance of the discharging screw in the original structure.

[0005] The embodiment of the present application provides a vertical high viscosity polymerization reaction device, which comprises:

[0006] The reactor has a sleeve-shaped sleeve part at the lower end.

[0007] The stirring mechanism is installed in the reactor, and has a stirring shaft inserted into the reactor.

[0008] The discharging mechanism is installed at the lower end of the reaction kettle and comprises a connecting seat, a discharging pipe, a driving member and a discharging screw rod.

[0009] The above embodiment has the beneficial effect that the connecting seat for expanding the diameter is configured, so that the diameter of the head blade of the discharging screw rod is larger than that of the blade in the discharging pipe, thereby increasing the contact area of the head of the discharging screw rod with the material. When the discharging screw rod needs to be disassembled or assembled, only the connecting seat needs to be disassembled and assembled, thereby improving the convenience of assembly and maintenance work.

[0010] On the basis of the above embodiment, the embodiment of the present application can also be improved as follows:

[0011] In one embodiment of the present application, the stirring shaft is connected with first stirring blades and second stirring blades. The shape of the first stirring blades matches the vertical shape of the inner wall of the reaction kettle. The second stirring blades are multiple and vertically spaced on the stirring shaft. The beneficial effect of this step is that the first stirring blades facilitate stirring of the material adhered to the inner wall of the reaction kettle due to the strong adhesion between the high-viscosity material and the inner wall of the reaction kettle, and the second stirring blades facilitate stirring of the material in the middle of the reaction kettle, thereby improving the stirring efficiency and effect of the material through the two stirring blades.

[0012] In one embodiment of the present application, the stirring shaft is further connected with third stirring blades, which are multiple and vertically spaced on the stirring shaft. The first stirring blades are located between the second stirring blades, and the third stirring blades are located in a staggered manner with the second stirring blades in the height direction. The beneficial effect of this step is that the third stirring blades in a staggered manner stir the material in different directions, thereby improving the stirring efficiency and effect.

[0013] In one embodiment of the present application, the discharging mechanism comprises a sealing gasket arranged between the upper end surface of the plug-in end and the hole bottom of the tapered hole. The beneficial effect of this step is that the sealing gasket forms a sealing structure between the end surfaces, thereby improving the sealing effect.

[0014] In one of the embodiments of the present application, the discharging mechanism further comprises a sealing ring sleeved on the outer periphery of the plug-in end, and the sealing ring is in contact with the hole wall of the conical hole. The beneficial effect of this step is that the sealing effect is improved by forming a seal between the outer periphery of the plug-in end and the hole wall of the conical hole through the sealing ring.

[0024] As Figure 1 , 2 indicated, a vertical high-viscosity polymerization reaction device includes a reaction kettle 1, a stirring mechanism 2, and a discharging mechanism 3. The reaction kettle 1 has a sleeve-shaped sleeve part 101 at the lower end. The stirring mechanism 2 is installed on the reaction kettle 1 and has a stirring shaft 201 extending into the reaction kettle 1. The discharging mechanism 3 is installed at the lower end of the reaction kettle 1 and includes a connecting seat 301, a discharging pipe 302, a driving part 303, and a discharging screw 304. The connecting seat 301 has an insertion end 305 at the upper end, which is inserted into the sleeve part 101. The insertion end 305 is provided with a tapered hole 306 with a large upper part and a small lower part. The discharging pipe 302 is connected to the lower end of the connecting seat 301. The discharging screw 304 is rotatably installed in the discharging pipe 302. The outer periphery of the blade at the upper end of the discharging screw 304 matches the shape of the tapered hole 306. The driving part 303 is connected to the lower end of the discharging pipe 302 and is connected to the discharging screw 304. The driving part 303 is used to drive the rotation of the discharging screw 304.

[0025] In some embodiments of the present application, as Figure 1 indicated, the reaction kettle 1 is further provided with a feeding port, an air inlet, and an exhaust port at the upper end. The lower end of the reaction kettle 1 is conical with a large upper part and a small lower part. The stirring mechanism 2 is installed on the kettle cover of the reaction kettle 1 and further includes a bracket and a motor. The bracket is installed on the kettle cover, and the motor is installed on the bracket. The output shaft of the motor is arranged vertically downward and connected to the stirring shaft 201 through a shaft coupling. The stirring shaft 201 is driven to rotate by the motor. The discharging pipe 302 is connected to a circulating pipeline through a circulating pump. A feeding screw is arranged in the circulating pipeline. The upper end of the circulating pipeline is connected to a feeding machine. The material is subjected to circulating reaction through the circulating pipeline. This structure is completely the same as the original patent technical solution, and will not be described here. The discharging pipe 302 is further connected to a discharging pipe 302 line through a feeding pump. The driving part 303 is an electric motor.

[0026] In some embodiments of the present application, as Figure 1As shown, the stirring shaft 201 is connected with a first stirring blade 202 and a second stirring blade 203. The first stirring blade 202 is shaped to match the vertical profile of the inner wall of the reaction kettle 1. The second stirring blade 203 is provided in multiple pieces and is vertically spaced on the stirring shaft 201. Since the high-viscosity material has strong adhesion with the inner wall of the reaction kettle 1, the first stirring blade 202 facilitates stirring of the material adhered to the inner wall of the reaction kettle 1, and the second stirring blade 203 facilitates stirring of the material in the middle of the reaction kettle 1, thereby improving the stirring efficiency and effect of the material through the two stirring blades.

[0027] In some embodiments of the present application, as shown in Figure 3 The first stirring blade 202 is concave in the direction of the incoming material. Through this guide structure, the material scraped off the inner wall of the reaction kettle 1 by the first stirring blade 202 can move along the surface of the first stirring blade 202 towards the direction of the second stirring blade 203, thereby reducing the resistance of the material to the first stirring blade 202 and guiding the material towards the middle, thereby improving the stirring efficiency.

[0028] In some embodiments of the present application, as shown in Figure 1 The stirring shaft 201 is further connected with a third stirring blade 204 provided in multiple pieces and vertically spaced on the stirring shaft 201. The first stirring blade 202 is located between the second stirring blades 203, and the third stirring blade 204 is vertically offset from the second stirring blades 203. The offset third stirring blade 204 stirs the material in different directions, thereby improving the stirring efficiency and effect.

[0029] In some embodiments of the present application, as shown in Figure 2 The discharge mechanism 3 includes a sealing gasket 307 provided between the upper end face of the plug-in end 305 and the hole bottom of the conical hole 306. The sealing gasket 307 forms a sealing structure between the end faces, thereby improving the sealing effect.

[0030] In some embodiments of the present application, as shown in Figure 2 The discharge mechanism 3 further includes a sealing ring 308 fitted around the outer periphery of the plug-in end 305, and the sealing ring 308 is in contact with the hole wall of the conical hole 306. The sealing ring 308 forms a seal between the outer periphery of the plug-in end 305 and the hole wall of the conical hole 306, thereby improving the sealing effect.

[0031] The vertical high-viscosity polymerization device has the connecting seat 301 for expanding the diameter, so that the head blade diameter of the discharging screw 304 is larger than the blade diameter in the discharging pipe 302, the contact area of the head of the discharging screw 304 and the material is increased, when the discharging screw 304 needs to be disassembled or assembled, only the connecting seat 301 needs to be disassembled and assembled, and the convenience of assembly and maintenance operation is improved.

[0032] The above is only the embodiment of the present application, and the common knowledge of the specific structure and characteristics in the scheme is not described in detail, the ordinary skilled in the art knows all the ordinary technical knowledge in the technical field of the present application before the application date or the priority date, can know all the prior art in the field, and has the ability to apply the conventional experimental means before the date, the ordinary skilled in the art can improve and implement the present scheme under the inspiration given in the present application, some typical known structures or known methods should not be an obstacle for the ordinary skilled in the art to implement the present application.
