Description

Technical Field

[0001] The utility model relates to the field of reactors, in particular to a raw material reactor for processing PVC rubber materials. Background Art

[0002] PVC, or polyvinyl chloride, is a thermoplastic formed by the polymerization of vinyl chloride monomer in the presence of an initiator. PVC is highly durable and maintains stable performance in a variety of environments. Its excellent waterproof properties make it widely used in water pipes and pipelines. PVC also offers excellent electrical insulation properties and is often used as insulation for wires and cables. The processing of PVC requires a reaction process on the raw materials, necessitating the use of a reactor.

[0003] When using a PVC rubber reactor, after the materials are placed inside the reactor, the stirring mechanism rotates to mix and stir the materials, while the heating mechanism heats the materials to reach the required reaction temperature. However, existing reactors typically use simple stirring blades for stirring, which have poor stirring effect. To achieve the required stirring effect, prolonged stirring is required, resulting in a long reaction time and unfavorable for rapid reaction processing. Existing reactors also often use electric heating or hydrothermal heating to increase the temperature. These two methods have poor uniformity, resulting in temperature differences within the reactor, which can also affect the reaction effect. Utility Model Content

Through the heating chamber 7, drain pipe 8, liquid inlet pipe 9, spiral heat exchange tube 10, air inlet 11 and exhaust port 12, a spiral heat exchange tube 10 is arranged inside the heating chamber 7. When in use, heat transfer liquid is injected into the heating chamber 7, and the flue gas with heat flows through the spiral heat exchange tube 10 to heat the heat transfer liquid, and the heat transfer liquid transfers the heat to the inside of the reactor body 1, which can improve the heating uniformity of the inside of the reactor body 1 and further ensure the reaction uniformity. It has a simple structure and excellent use effect.

[0018] When the raw materials of PVC rubber are processed by reaction, legs are set on the support frame 15 on the outer wall of the reactor body 1, and the reactor is supported and placed by the legs. After connecting the corresponding pipes and lines, the reactor is started to be used. First, heat transfer liquid is injected into the heating chamber 7 through the liquid inlet pipe 9. After the heat transfer liquid is filled, the raw materials are added to the interior of the reactor body 1 through the feed pipe 14 on the top cover 2. After the feed pipe 14 is closed, the motor 4 on the connecting seat 3 is started. The motor 4 rotates with the stirring structure 6 through the rotating shaft 5, thereby stirring the raw materials. At the same time, the smoke generated by other processing steps is The gas enters the spiral heat exchange tube 10 through the air inlet 11, and finally the flue gas is discharged from the exhaust port 12. During this process, the spiral heat exchange tube 10 transfers the heat in the flue gas to the heat transfer fluid, and then transfers it to the interior of the reactor body 1 through the heat transfer fluid, thereby heating the material, so as to provide a temperature guarantee for the reaction effect of the material. After the material reaction is completed, the valve at the discharge pipe 13 can be opened to discharge the material.

[0019] According to the above embodiment, the stirring structure 6 includes a first mounting seat 601, a second mounting seat 602, a reinforcing plate 603, a connecting plate 604, a connecting bolt 605, a layered stirring assembly 606 and a fixing bolt 607. The first mounting seat 601 and the second mounting seat 602 are mounted on the rotating shaft 5 by the fixing bolt 607. The reinforcing plate 603 and the connecting plate 604 are fixed together, and the two groups of reinforcing plates 603 and the connecting plate 604 are respectively fixedly connected to the first mounting seat 601 and the second mounting seat 602.

The layered stirring assembly 606 is installed on the connecting plate 604 through the connecting bolts 605. The spiral stirring blades 6063 arranged in layers on the vertical plate 6061 can increase the mixing effect of the materials during stirring, thereby improving the stirring effect, and can achieve uniform mixing of the materials in a short time, which can not only ensure the uniformity of the reaction, but also increase the reaction rate and shorten the entire reaction cycle. The connecting vertical rod 6064 is used to strengthen the stability of the spiral stirring blade 6063 and ensure the use effect.

[0020] When installing the stirring structure 6, first use the connecting bolts 605 to cooperate with the mounting holes 6062 to fix the vertical plate 6061 to the connecting plate 604, then set the first mounting seat 601 and the second mounting seat 602 to the rotating shaft 5, and use the fixing bolts 607 to fix the mounting seats, thereby realizing the installation of the entire stirring structure 6. When the stirring structure 6 is in use, after the rotating shaft 5 rotates, the mounting seat rotates with the connecting plate 604, thereby rotating with the layered stirring component 606.
