Description

Technical Field

[0001] This utility model relates to the field of synthetic resin technology, and in particular to a condensation and reflux device for synthetic resin. Background Technology

[0002] Synthetic resin is a class of artificially synthesized high molecular weight polymers that possess or exceed the inherent properties of natural resins. Synthetic resin is defined as an organic substance that is a solid, semi-solid, or pseudo-solid with an undefined molecular weight but often a high molecular weight. Existing devices control the gas pressure by installing a fixed pressure valve on the reactor. When the gas pressure inside the reactor reaches the preset value, the pressure valve opens, and steam enters the condenser through a fixed pipe, where condensation is achieved by heat exchange between cooling water and steam.

[0003] An existing authorized announcement number describes a synthetic resin condensation and reflux device, comprising a shell, feet, a liquid outlet pipe, a connecting interface, a connecting pipe, a cooling fan, a control component, a heat-conducting component, a collection hopper, and a pressure relief valve. The control component is connected to the cooling fan; the cooling fan is connected to the inner wall of the shell; and the bottom of the cooling fan is connected to the heat-conducting component. The combination of the connecting pipe and the connecting interface effectively improves the installation efficiency of this device and reduces the difficulty of combining it with other equipment. The bottom air inlet structure of this device effectively improves the reflux efficiency. At the same time, the bottom-up cooling method allows the resin vapor to fully contact the condensing plate inside the heat-conducting component during the upward condensation process, thus facilitating the accumulation of the condensed raw material inside the collection hopper and its flow out through the liquid outlet pipe. The pressure relief valve structure prevents blockage caused by excessive raw material inside the collection hopper, thereby reducing the maintenance cost of this device.

[0004] Regarding the aforementioned related technologies, the existing condensation reflux device for synthetic resins has a drawback: the opening pressure of the fixed pressure valve is preset and cannot be flexibly adjusted according to the dynamic changes in gas pressure during the reaction process, easily leading to excessively high or low gas pressure. Excessively high gas pressure may cause overpressure in the reactor, posing a safety hazard; excessively low gas pressure will affect the normal progress of the reaction, reducing the reaction rate and product quality. Therefore, this utility model provides a condensation reflux device for synthetic resins. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1: Reference Figure 1-4The condensation and reflux device for synthetic resin shown includes a reactor 1, which is used to contain the reactants of the synthetic resin and provide space for the reaction. A guide pipe 2 is fixedly connected to the top of the reactor 1. The guide pipe 2 is used to guide the high-temperature steam generated in the reaction in the reactor 1 and deliver the steam to the subsequent condensation components. A linkage assembly is fixedly connected inside the guide pipe 2. This assembly includes a first sliding plate 10, which provides an initial sliding track for the slider 12, restricting its movement within a certain range and guiding and limiting its motion. A second sliding plate 11 is also fixedly connected inside the guide pipe 2. After the slider 12 passes the first sliding plate 10, the second sliding plate 11 provides a track for its continued sliding, cooperating with the first sliding plate 10 to change the trajectory of the slider 12, thereby controlling the steam flow path. The guide pipe 2 contains a slider 12, which slides simultaneously on both the first and second sliding plates 10. The sliding of the slider 12 controls the opening and closing of the steam channel. When the gas pressure inside the reactor 1 increases, the steam pushes up the slider 12, causing it to move and change the steam flow state. A spring 13 is fixedly connected to the top of the slider 12, providing a restoring force for the slider 12. When the gas pressure inside the reactor 1 decreases... When the spring 13 pushes the slider 12 back to its original position, it closes the steam passage and ensures the normal operation of the device. The other end of the spring 13 is fixedly connected to a vent plate 14, which supports the spring 13. At the same time, its side wall is fixedly connected to the inner side wall of the guide pipe 2 to ensure the sealing of the guide pipe 2 and prevent steam leakage. The side wall of the guide pipe 2 is fixedly connected to a connecting pipe 3, which is used to transport the steam in the guide pipe 2 to the condensing chamber 4, providing a channel for steam transmission and ensuring that the steam can smoothly enter the subsequent condensation treatment stage. The condensing chamber 4 is set on the outside of the connecting pipe 3. The condensing chamber 4 provides space for the condensation of steam and liquefies the steam through the internal cooling environment. The connecting pipe 3 passes through the condensing chamber 4. One end of the connecting pipe 3 is fixedly connected to a connecting annular conduit 17. The annular conduit 17 is inside the condensing chamber 4. The annular conduit 17 increases the contact area between the steam and the cooling medium in the condensing chamber 4, so that the steam can more fully exchange heat with the cooling medium and improve the condensation efficiency.

[0020] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that one end of the annular conduit 17 is fixedly connected to a connecting return pipe 7, which passes through the condensation chamber 4. The return pipe 7 is used to transport the condensed liquid material in the annular conduit 17 back to the reactor 1, realizing the recycling of materials and improving the utilization rate of raw materials. One end of the return pipe 7 is fixedly connected to the side wall of the reactor 1 to ensure that the returned liquid material can smoothly enter the reactor 1 to participate in the reaction. A chiller 5 is installed on the outside of the condensation chamber 4. The chiller 5 is used to cool the water and provide a low-temperature cooling medium for the condensation process, ensuring that the steam can be effectively condensed. A first water pump 6 is installed on the top of the chiller 5. The first water pump 6 is used to extract the water cooled by the chiller 5 and transport it to the condensation chamber 4 through the conveying pipe 8 to provide power for the condensation process. The output end of the first water pump 6 is fixedly connected to the conveying pipe 8, which is used to transport the water cooled by the chiller 5 to the connecting shell 16. One end of the conveying pipe 8 is fixedly connected to the connecting shell 16. 6 is used to collect the cooling water delivered by the conveying pipe 8 and distribute it to multiple spray heads 15. The side wall of the connecting shell 16 is fixedly connected to the inner side wall of the condenser 4 to ensure the stability and sealing of the connection. Multiple spray heads 15 are fixedly connected to the bottom of the connecting shell 16. The spray heads 15 spray the cooling water evenly onto the annular guide tube 17, so that the steam in the annular guide tube 17 is quickly cooled and liquefied. The inner bottom wall of the condenser 4 is fixedly connected to the collection box 18, which is used to collect the remaining cooling water after the spray heads 15 spray, providing storage space for the recycling of cooling water. The side wall of the collection box 18 is provided with a second water pump 9, which is used to extract the cooling water in the collection box 18 and send it back to the chiller 5 through the circulation pipe 19 to realize the recycling of cooling water and save water resources. The output end of the second water pump 9 is fixedly connected to the circulation pipe 19, which is used to connect the second water pump 9 and the chiller 5, providing a channel for the circulation of cooling water and ensuring that the cooling water can smoothly return to the chiller 5 for recooling.

[0021] The working principle of this device is as follows: When using this device, the material first reacts in the reactor 1 to generate high-temperature steam. At this time, the gas pressure in the reactor 1 increases, and the steam enters the guide pipe 2 to push the slider 12 upward. The slider 12 squeezes the spring 13 and moves along the first slide plate 10 and the second slide plate 11 at the same time. As the slider 12 continues to rise, it will pass the first slide plate 10 and move along the second slide plate 11. At this time, the steam can pass through the groove of the slider 12, through the blockage of the slider 12, through the vent plate 14, and through the connecting pipe 3 into the condensing chamber 4 and into the annular conduit 17. At this time, the water inside is cooled by the chiller 5 and sent to the condensing chamber 4 through the conveying pipe 8 by the first water pump 6. The annular conduit 17 is cooled by the spray head 15. After cooling is completed, it is sent back to the reactor 1 through the return pipe 7.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
