Description

Technical Field

[0001] This invention belongs to the field of industrial technology, specifically relating to an easily removable exothermic polymerization reaction apparatus for PVC production. Background Technology

[0002] Polyvinyl chloride (PVC) is a polymer formed by the polymerization of vinyl chloride monomer (VCM) under free radical polymerization mechanisms, using initiators such as peroxides and azo compounds, or under the influence of light and heat. The polymerization principle of PVC involves using deionized water as a dispersion system, PVA as a dispersant, and peroxide as an initiator, to polymerize 99.99% pure VCM into PVC resin that meets various standards. The VCM polymerization reaction is exothermic, characterized by hysteresis and nonlinearity. A significant portion of the production process involves temperature control; improving the heat exchange capacity of the polymerization reactor is crucial for increasing equipment productivity. Existing PVC production uses an easily removable, exothermic polymerization reactor, but its heat exchange capacity is low. Furthermore, it generates vortices during stirring, leading to uneven mixing, and its cooling is excessively slow. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide an easily removable exothermic polymerization reaction device for PVC production. This invention solves the problems of existing easily removable exothermic polymerization reaction devices for PVC production, which have low heat exchange capacity, generate vortices during stirring leading to uneven stirring, and are too slow to cool.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an easily removable exothermic polymerization reaction apparatus for PVC production, comprising a stirring tank, a fixed slider fixedly mounted on the side of the stirring tank, a fixed slip ring slidably mounted on the outer side of the fixed slider, four support legs fixedly mounted on the bottom of the fixed slip ring, two support columns fixedly mounted on the top of the fixed slip ring, a support plate fixedly mounted on one end of each support column, a fixed block fixedly mounted on the top of the support plate, a rotary motor fixedly mounted on the top of the fixed block, a rotating column fixedly mounted on one end of the rotary motor, a fan fixedly mounted in the middle of the rotating column, a bevel gear A fixedly mounted on one end of the rotating column, a bevel gear B meshing inside the support column, a rotating shaft inserted and fixedly mounted inside the bevel gear B, and a bevel gear C fixedly mounted near the bottom of the rotating shaft. A connecting column is movably mounted on the side of the mixing tank. A bevel gear D is fixedly mounted on one end of the connecting column. Multiple stirring columns are fixedly mounted on the surface of the connecting column. An arc-shaped stirring paddle is fixedly mounted on the bottom end of the rotating shaft. An installation plate is fixedly mounted near the top of the rotating shaft. Two coolant storage tanks are fixedly mounted on the top of the installation plate. A conduit is fixedly mounted on the side of the coolant storage tank. A pump is fixedly mounted on one end of the conduit. A cooling pipe is fixedly mounted on the bottom end of the coolant storage tank. An intelligent heating device is fixedly mounted on the top of the installation plate. A heating pipe is fixedly mounted on the bottom end of the intelligent heating device. A liquid storage tank is fixedly mounted on one end of the heating pipe. A protective shell is fixedly mounted on the top of the mixing tank. A ventilation opening is provided on the side of the protective shell. A feed inlet is inserted into the top of the protective shell. A bellows box is fixedly mounted on the top of the support plate. A discharge port is fixedly mounted on the top of the mixing tank.

[0005] Preferably, the fan is installed inside the air box.

[0006] The advantage of the above technical solution is that the fan is installed inside the air box, and the fan rotates simultaneously with the rotating column installed inside the fan to form a heat dissipation structure, while the air box also protects the fan.

[0007] Preferably, the intelligent heating device and the liquid storage tank are connected by a heating pipe to form a circulation structure.

[0008] The advantage of the above technical solution is that the intelligent heating device and the storage tank are connected by heating pipes to form a circulation structure, so that the liquid inside the storage tank enters the intelligent heating device for heating and then the heated liquid is introduced into the heating pipe inside the mixing tank to circulate and heat the production materials inside the device.

[0009] Preferably, the two coolant storage tanks and the pump are connected by conduits and cooling pipes to form a circulation structure.

[0010] The advantage of the above technical solution is that the coolant storage tank and the pump are connected by conduits and cooling pipes to form a circulation structure. The pump then guides the coolant from the two coolant storage tanks into the cooling pipes inside the mixing tank for circulation, thereby exchanging internal heat and achieving a cooling effect.

[0011] Preferably, the fixed slider slides inside the fixed slip ring, and the specifications and dimensions of the fixed slider are adapted to those of the fixed slip ring.

[0012] The advantage of the above technical solution is that the fixed slider slides inside the fixed slip ring, thereby effectively fixing the position of the mixing tank while it is rotating.

[0013] Preferably, one end of the connecting column is movably connected to the mixing tank, and the other end is movably connected to the rotating shaft. A bevel gear D is fixedly installed near the rotating shaft, and the bevel gear D meshes with the bevel gear C.

[0014] The advantages of the above technical solution are that one end of the connecting column is movably connected to the mixing tank, and the other end is movably connected to the rotating shaft. A bevel gear D is fixedly installed near the rotating shaft. The bevel gear D meshes with the bevel gear C, so that when the bevel gear C rotates, it drives the connecting column to rotate and drives the mixing tank to rotate. This prevents the generation of vortices during stirring, which would lead to uneven stirring. When the bevel gear C rotates, it drives the two meshing bevel gears D to rotate synchronously, so that the stirring column rotates and stirs.

[0015] Preferably, the two bevel gears B are meshed with a bevel gear A in the middle.

[0016] The advantage of the above technical solution is that a bevel gear A meshes between the two bevel gears B, thereby transmitting kinetic energy to the shaft through the rotation of the bevel gear A.

[0017] Preferably, ventilation openings are provided on the left and right sides of the protective shell, and an air outlet is provided on one side of the bellows box.

[0018] The advantage of the above technical solution is that ventilation openings are provided on the left and right sides of the protective shell, and an air outlet is provided on one side of the air box. Thus, when the fan is running, the air blown by it enters the interior of the protective shell through the ventilation openings and the air outlet to dissipate heat from the device inside the protective shell.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. When using the device, the material is first introduced into the mixing tank through the feed inlet. Then, the rotating motor starts running, synchronously driving the rotating column and fan to rotate, dissipating heat from the inside of the protective shell. Next, the rotating shaft is driven to rotate through the meshing of bevel gear B and bevel gear A. When the rotating shaft rotates, the mounting plate on the surface of the rotating shaft rotates synchronously, and bevel gear D, through meshing with bevel gear C, synchronously drives the mixing tank and the mixing column to rotate, stirring the material inside the mixing tank. Then, the intelligent heating device starts running, heating the liquid inside the storage tank and introducing it into the heating pipe to heat the material inside the mixing tank. After heating, the operation of the pump introduces the coolant from the two coolant storage tanks into the cooling pipe to exchange heat and cool the heated material inside the mixing tank.

[0020] 2. A fan is installed inside the air box, and its internal rotating column creates a cooling structure. The air box also protects the fan. The intelligent heating device and the liquid storage tank are connected by heating pipes to form a circulation structure. The liquid in the storage tank enters the intelligent heating device for heating and is then introduced into the heating pipes inside the mixing tank to circulate and heat the production materials inside the device. The coolant storage tank and the pump are connected by conduits and cooling pipes to form a circulation structure. The pump introduces the coolant from the two coolant storage tanks into the cooling pipes inside the mixing tank for circulation, exchanging heat and achieving a cooling effect.

[0021] 3. A fixed slider slides inside a fixed slip ring, effectively fixing the position of the mixing tank while it rotates. One end of the connecting column is movably connected to the mixing tank, and the other end is movably connected to a rotating shaft. A bevel gear D is fixedly installed near the rotating shaft. Bevel gear D meshes with bevel gear C, so that the rotation of bevel gear C drives the connecting column to rotate and the mixing tank to rotate, thus preventing the generation of vortices during mixing and causing uneven mixing. When bevel gear C rotates, it drives the two meshing bevel gears D to rotate synchronously, causing the mixing column to rotate and mix. A bevel gear A meshes between the two bevel gears B, so that the rotation of bevel gear A transmits kinetic energy to the rotating shaft. Ventilation openings are provided on the left and right sides of the protective shell, and an air outlet is provided on one side of the bellows box. When the fan is running, the air blown by it enters the interior of the protective shell through the ventilation openings and the air outlet to dissipate heat from the device inside the protective shell.

A feed inlet 15 is inserted into the top of the protective shell 13. A bellows box 6 is fixedly installed on the top of the support plate 5. A discharge port 3 is fixedly installed on the top of the mixing tank 1.

[0026] The working principle of the above technical solution is as follows: When the device is in use, the material is first introduced into the mixing tank 1 through the feed port 15. Then, the rotary motor 16 starts running, synchronously driving the rotating column 9 and the fan 8 to rotate, dissipating heat from the inside of the protective shell 13. Next, the rotating shaft 11 is driven to rotate through the meshing of the bevel gear B12 and the bevel gear A10. When the rotating shaft 11 rotates, the mounting plate 32 installed on the surface of the rotating shaft 11 rotates synchronously, and the bevel gear D28 drives the mixing tank 1 and the stirring column 31 to rotate synchronously through the meshing of the bevel gear C27, stirring the material inside the mixing tank 1. Then, the intelligent heating device 20 starts running, heating the liquid inside the storage tank 21 and introducing it into the heating tube 25 to heat the material inside the mixing tank 1. After heating, the pump 23 introduces the coolant from the two coolant storage tanks 22 into the cooling tube 26 to exchange heat and cool the heated material inside the mixing tank 1.

[0027] In another implementation scheme, as shown in Figures 1-5, the fan 8 is installed inside the air box 6, and rotates simultaneously with the rotating column 9 installed inside the fan 8 to form a wind cooling structure. The air box 6 also protects the fan 8. The intelligent heating device 20 and the liquid storage tank 21 are connected by the heating pipe 25 to form a circulation structure.

[0028] In another embodiment, as shown in Figures 1-5, the coolant storage tank 22 and the pump 23 are connected by the conduit 24 and the cooling pipe 26 to form a circulation structure. The pump 23 then guides the coolant from the two coolant storage tanks 22 into the cooling pipe 26 inside the mixing tank 1 for circulation, thereby exchanging heat and achieving a cooling effect. The fixed slider 19 slides inside the fixed slip ring 18, so that the mixing tank 1 can be effectively fixed in position while rotating.

[0029] In another embodiment, as shown in Figures 1-5, one end of the connecting column 30 is movably connected to the stirring tank 1, and the other end is movably connected to the rotating shaft 11. A bevel gear D28 is fixedly installed near the end of the rotating shaft 11. The bevel gear D28 meshes with the bevel gear C27, so that when the bevel gear C27 rotates, it drives the connecting column 30 to rotate and drives the stirring tank 1 to rotate, thereby preventing the generation of vortices during stirring and causing uneven stirring. When the bevel gear C27 rotates, it drives the two meshing bevel gears D28 to rotate synchronously, causing the stirring column 31 to rotate and stir. A bevel gear A10 meshes between the two bevel gears B12, thereby transmitting kinetic energy to the rotating shaft 11 through the rotation of the bevel gear A10. Ventilation ports 14 are provided on the left and right sides of the protective shell 13, and an air outlet 7 is provided on one side of the bellows box 6. So that when the fan 8 moves, the air blown by it passes through the ventilation ports 14 and the air outlet 7. Enter the interior of the protective housing 13 to dissipate heat from the devices inside the protective housing 13.

[0030] The working principle and usage process of this invention: The fan 8 is installed inside the air box 6, and rotates simultaneously with the rotating column 9 installed inside the fan 8, forming a wind-heating structure. The air box 6 also protects the fan 8. The intelligent heating device 20 and the liquid storage tank 21 are connected by a heating pipe 25 to form a circulation structure. Liquid inside the liquid storage tank 21 enters the intelligent heating device 20 for heating, and then the heated liquid is introduced into the heating pipe 25 inside the stirring tank 1 to circulate and heat the production materials inside the device. The coolant storage tank 22 and the pump 23 are connected by a conduit 24 and a cooling pipe 26 to form a circulation structure. The pump 23 introduces the coolant from the two coolant storage tanks 22 into the cooling pipe 26 inside the stirring tank 1 for circulation, exchanging heat and achieving a cooling effect. The fixed slider 19 slides inside the fixed slip ring 18, effectively fixing the position of the stirring tank 1 while it rotates. The connecting column 30... One end of the device is movably connected to the mixing tank 1, and the other end is movably connected to the rotating shaft 11. A bevel gear D28 is fixedly installed near the end of the rotating shaft 11. The bevel gear D28 meshes with the bevel gear C27, so that when the bevel gear C27 rotates, it drives the connecting column 30 to rotate and drives the mixing tank 1 to rotate, thereby preventing the generation of vortices during stirring and causing uneven stirring. When the bevel gear C27 rotates, it drives the two meshing bevel gears D28 to rotate synchronously, causing the stirring column 31 to rotate and stir. A bevel gear A10 meshes between the two bevel gears B12, so that the rotation of the bevel gear A10 transmits kinetic energy to the rotating shaft 11. Ventilation ports 14 are opened on the left and right sides of the protective shell 13, and an air outlet 7 is opened on one side of the bellows box 6. So that when the fan 8 moves, the air blown by it enters the interior of the protective shell 13 through the ventilation ports 14 and the air outlet 7. The internal device dissipates heat.

[0031] When the device is in use, the material is first introduced into the mixing tank 1 through the feed port 15. Then, the rotary motor 16 starts running, synchronously driving the rotating column 9 and the fan 8 to rotate, dissipating heat from the inside of the protective shell 13. Next, the rotating shaft 11 is driven to rotate through the meshing of the bevel gear B12 and the bevel gear A10. When the rotating shaft 11 rotates, the mounting plate 32 installed on the surface of the rotating shaft 11 rotates synchronously, and the bevel gear D28 drives the mixing tank 1 and the stirring column 31 to rotate synchronously through the meshing of the bevel gear C27, stirring the material inside the mixing tank 1. Then, the intelligent heating device 20 starts running, heating the liquid inside the storage tank 21 and introducing it into the heating tube 25 to heat the material inside the mixing tank 1. After heating, the pump 23 introduces the coolant from the two coolant storage tanks 22 into the cooling tube 26 to exchange heat and cool the heated material inside the mixing tank 1.
