Description

The inconsistent temperatures at different locations in the polymer material will affect the subsequent devolatilization of the polymer, the devolatilization efficiency of the polymer, and the quality of the final polymer.

In addition, the dividing structure is arranged along the axial direction of the heat exchange tube, which can effectively shear the polymer and has little resistance to the polymer. The devolatilization time of the polymer will hardly be affected, which is beneficial to improving the devolatilization efficiency of the polymer and the quality of the final polymer obtained, and to a certain extent solves the technical problem of the devolatilization efficiency of the polymer material and the quality of the obtained polymer.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0032] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" 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 the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0034] In the related art, for some polymers with higher viscosity, such as polyolefin elastomers and other types of polymers, uneven heating is prone to occur during the devolatilization process when heated by a heating device, which affects the subsequent devolatilization process, the overall devolatilization efficiency of the polymer and the final polymer performance and quality; in some related technologies, setting up multiple overly complex structures in the heat exchange tube to divide the polymer will have a large resistance to the polymer, and will also affect the polymer flow and overall devolatilization efficiency. There is also a technical problem that the heating efficiency of the polymer and the quality of the final polymer are affected. The embodiment of the present application provides a heating device that can at least solve the above technical problems to a certain extent.

[0035] It should be noted that since polymers such as polyolefin elastomers already have very high viscosity when heated for devolatilization, simple temperature changes will hardly reduce the viscosity of polyolefin elastomers. The heating device in this application is mainly used to heat the polymer to adjust the temperature of the polymer before actual devolatilization.

[0036] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0037] Figure 1 A schematic diagram of the structure of a heating device in some embodiments or certain embodiments of the present application is shown. Figure 2 A schematic diagram of the structure of a mixing element in some embodiments or certain embodiments of the present application is shown, combined with Figure 1 and Figure 2 , an embodiment of the present application provides a heating device, comprising:

[0038] The heat exchange container 1 is provided with two temperature control chambers 11 spaced apart from each other and a heat exchange chamber 12 located between the two temperature control chambers 11 . The heat exchange container 1 is also provided with a connecting port 13 correspondingly connected to each temperature control chamber 11 .

[0039] The heat exchange tube 2 is disposed in the heat exchange chamber 12 and has two ends connected to the two temperature control chambers 11 respectively.

[0040] The first heater 3 is connected to the heat exchange container 1 and communicated with the heat exchange chamber 12 so as to pass the heat exchange medium into the heat exchange chamber 12 .

[0041] The mixing element 4 includes a dividing structure 41 which is arranged in the heat exchange tube 2 along the axial direction of the heat exchange tube 2 and is used to divide the space in the heat exchange tube 2 , and a fixing member 42 which is arranged at one end of the heat exchange tube 2 and connected to the dividing structure 41 .

[0042] The heat exchange container 1 is the main structure of the heating device. The heat exchange container 1 has two temperature control chambers 11 and a heat exchange chamber 12 located between the two temperature control chambers 11. The heat exchange container 1 is also provided with a connecting port 13 corresponding to each temperature control chamber 11. When the polymer-related material needs to be heated, the material can first enter the corresponding temperature control chamber 11 from the connecting port 13 of one temperature control chamber 11. The temperature control chamber 11 can accumulate a certain amount of material to prevent the material from being cut off, and can make the temperature of the material in the temperature control chamber 11 change to a certain extent. The temperature of the material is adjusted differently according to the equipment connected to the heating device. The material in the temperature control chamber 11 then enters the heat exchange tube 2 from the heat exchange tube 2 connected to the temperature control chamber 11. Since the heat exchange tube 2 is located in the heat exchange chamber 12 and the first heater 3 is connected to the heat exchange chamber 12, the first heater 3 will also heat the heat exchange tube 2 when the heat exchange medium is passed into the heat exchange chamber 12. The heated heat exchange tube 2 can heat the polymer material in the heat exchange tube 2. The mixing element 4 in the heat exchange tube 2 includes a dividing structure 41 which is arranged in the heat exchange tube 2 along the axial direction of the heat exchange tube 2 and divides the space in the heat exchange tube 2. The dividing structure 41 is connected to a fixing member 42, and the fixing member 42 is fixed at one end of the heat exchange tube 2. After the polymer-related material enters the heat exchange tube 2 from one end of the heat exchange tube 2, it will directly contact the dividing structure 41 arranged along the axial direction of the heat exchange tube 2, and will be sheared and divided by the dividing structure 41, so that the agglomerated polymer is separated, and the polymer material can exchange heat with the heat exchange tube 2 more evenly, and the polymer is heated more evenly, which can reduce the influence of uneven heating on the subsequent devolatilization process, and the dividing structure 41 is arranged along the axial direction of the heat exchange tube 2, which can effectively shear the polymer and has little resistance to the polymer, and the devolatilization time of the polymer will hardly be affected, which is conducive to improving the devolatilization efficiency of the polymer and the quality of the final polymer, and to a certain extent solves the technical problem that the devolatilization efficiency of the polymer material and the quality of the obtained polymer are affected.

[0043] Moreover, the segmentation structure 41 in the mixing element 4 is mainly connected to one end of the heat exchange tube 2 through a fixing part 42. The connection between the mixing element 4 and the heat exchange tube 2 is simple, which is convenient for maintenance and replacement of the heating device. The mixing element 4 and the heat exchange tube 2 can also be prepared separately, which is also beneficial to reducing the preparation cost of the heating device.

[0044] It should be noted that the heat exchange chamber 12 is located between the two insulation chambers, each insulation chamber is provided with a connecting port 13, and both ends of the heat exchange tube 2 located in the heat exchange chamber 12 are respectively connected to the two insulation chambers. If the polymer-related materials need to be heated, the polymer-related materials or fluids can enter from a connecting port 13 of the insulation chamber according to the needs, and then enter the heat exchange tube 2 in the heat exchange chamber 12 for heat exchange, and finally enter the other insulation chamber from the heat exchange tube 2 and then flow out from the connecting port 13 of the other insulation chamber for subsequent devolatilization.

[0045] In some or certain embodiments, the segmentation structure 41 is provided with a plurality of segmentation parts 411 fixedly connected in sequence in the axial direction of the heat exchange tube 2, the segmentation parts 411 are X-shaped, and the angle α of the plurality of segmentation parts 411 toward one end of the heat exchange tube 2 decreases in sequence in the axial direction of the heat exchange tube 2.

[0046] The segmentation structure 41 is provided with a plurality of X-shaped segmentation parts 411 which are fixedly connected in sequence in the axial direction of the heat exchange tube 2, which is convenient for preparation, can effectively cut the polymer, and has little resistance to the polymer, can ensure the stable flow of the polymer and the subsequent devolatilization process, effectively improve the uniform heating degree of the polymer, so as to improve the quality of the final polymer. And the design of this structure can make the high viscosity polymer fluid obtain better differentiation and mixing effect at the end of the heat exchange tube 2 with a larger angle α when flowing into the heat exchange tube 2, increase the shear rate, thereby reducing the viscosity of the polymer and effectively dispersing the polymer. As the fluid moves to the other end of the heat exchange tube 2, the pressure drop at the other end of the heat exchange tube 2 can be reduced, the flow rate of the polymer can be increased, the energy consumption of the fluid can be reduced, the polymer can be heated uniformly and the flow of the polymer can be promoted at the same time, so as to improve the devolatilization efficiency of polymer-related materials.

[0047] It should be noted that, according to usage requirements, the polymer material can enter from one end of the heat exchange tube 2 where the angle α of the dividing portion 411 is smaller, and flow out from the other end of the heat exchange tube 2 where the angle α of the dividing portion 411 is larger.

[0048] In some or certain embodiments, the dividing portion 411 of the dividing structure 41 may be X-shaped, and the dividing portions 411 of the dividing structure 41 may be in the same plane, and the axis of the heat exchange tube 2 is located in the plane where the dividing portion 411 of the dividing structure 41 is located. Then the dividing structure 41 can divide the circumferential space of the heat exchange tube 2 nearly equally, and can more effectively divide the polymer entering one end of the heat exchange tube 2, and the X-shaped dividing portion 411 can achieve effective cutting while having almost no resistance to the polymer, and the dividing portion 411 itself and the two connected dividing portions 411 have a large flow space, which can effectively ensure the cutting of the polymer and the overall fluidity, prevent the polymer from being cut off, and is conducive to improving the overall devolatilization efficiency of the polymer and improving the uniformity of heating of the polymer.

[0049] It should be noted that Figure 2 The mixing element 4 in Figure 1 The mixing element 4 in the dividing structure 41 is provided with an adjustment for the included angle α corresponding to the X-shaped dividing portion 411. The diameter of the heat exchange tube 2 is usually constant, and when the included angle α of the X-shaped dividing portion 411 in the dividing structure 41 changes, the dividing portion 411 itself and the space between the two connected dividing portions 411 will change, so the material flow rate of the polymer can be adjusted.

[0050] Figure 3 A schematic diagram showing another segmentation structure in some embodiments or certain embodiments of the present application is shown, referring to Figure 3 It can be seen that in some or certain embodiments, the segmentation structure 41 may also include a plurality of first segmentation pieces 412 and second segmentation pieces 413 alternately fixedly connected along the axial direction of the heat exchange tube 2, the first segmentation piece includes a plurality of first X structures 4121 fixedly connected in sequence along the axial direction of the heat exchange tube 2, and the second segmentation piece 413 includes a plurality of second X pieces 4131 fixedly connected in an array.

[0051] In the heat exchange tube 2, the second dividing piece 413 formed by the second X-pieces 4131 fixedly connected in an array can divide the polymer into smaller pieces relative to the first dividing piece 412 to which the plurality of first X-structures 4121 are alternately fixedly connected along the axial direction of the heat exchange tube 2. Both the first dividing piece 412 and the second dividing piece 413 are arranged along the axial direction of the heat exchange tube 2. Both sides of the dividing structure 41 can have space for the polymer to flow, and there is almost no effect on the fluidity of the polymer.

[0052] In some or certain embodiments, the first X structure 4121 may be a structure obtained by stacking a plurality of X sheets flush with each other, or may be an X plate with a certain thickness.

[0053] In some or certain embodiments of the present application, the segmentation structure 41 may be configured as follows: Figure 1 , Figure 2 or Figure 3 In the structure, the segmentation structure 41 can be connected to the heat exchange tube 2 through the fixing member 42.

[0054] In some or certain embodiments, the segmentation structure 41 extends from one end of the heat exchange tube 2 to the other end of the heat exchange tube 2 , and the fixing member 42 is annular, and the outer peripheral wall is fixed to the inner peripheral wall of the heat exchange tube 2 .

[0055] The segmentation structure 41 extends from one end of the heat exchange tube 2 to the other end of the heat exchange tube 2, and can cut and separate the polymer material, which is beneficial to improving the uniformity of the heating of the polymer. The segmentation structure 41 is connected to the annular fixing member 42, and then fixed to the inner circumferential wall of the heat exchange tube 2 through the outer circumferential wall of the annular fixing member 42. It is convenient to realize the connection between the fixing member 42 and the heat exchange tube 2, and it is convenient to replace the mixing element 4, which is beneficial to improve the maintenance efficiency of the heating device.

[0056] In some or certain embodiments, the annular fixing member 42 and the heat exchange tube 2 may be interference fit, so as to facilitate the disassembly and assembly of the heat exchange tube 2 and the mixing element 4 and facilitate replacement and maintenance.

[0057] In some or certain embodiments, there is a gap between the segmentation structure 41 and the inner circumferential wall of the heat exchange tube 2. While effectively cutting the polymer-related materials, the polymer has a large flow space, and can reduce the friction between the segmentation structure 41 and the heat exchange tube 2 and the possibility of impurities being mixed into the polymer, which is beneficial to improving the service life of the heating device and the quality of the final polymer.

[0058] In some or certain embodiments, the fixing member 42 may also be a circular plate with holes of different shapes in the middle, so as to achieve a convenient connection with the heat exchange tube 2.

[0059] In some or certain embodiments, the heat exchange container 1 includes a cylinder 14 and a head 15 that seals both ends of the cylinder 14, and a partition 16 arranged between each head 15 and the cylinder 14. The two partitions 16 are connected at both ends of the cylinder 14 to form a heat exchange chamber 12. The corresponding head 15 is connected to the partition 16 through a fixed welded flange, and a temperature control chamber 11 is formed between the head 15 and the partition 16. The two ends of the heat exchange tube 2 are respectively connected to the corresponding partition 16 to be connected to the corresponding temperature control chamber 11.

[0060] The heat exchange container 1 is prepared by using a cylinder 14 , a head 15 and a partition 16 , which has a low preparation cost and is also convenient for connecting and installing the heat exchange tubes 2 .

[0061] In some or certain embodiments, the end cap 15 may include an elliptical main body and an inlet and outlet pipe inserted into and connected to the main body, and the pipe opening of the inlet and outlet pipe body may form a communication port 13 for material in and out. The axis of the inlet and outlet pipe, the axis of the main body and the axis of the cylinder 14 may all extend in the same direction, facilitating the flow of polymer-related materials.

[0062] In some or certain embodiments, one end of the heat exchange tube 2 is connected to the corresponding partition 16, and the partition 16 is provided with a plurality of through holes (not shown in the figure), and both ends of the through holes are respectively connected to the tube hole of the heat exchange tube 2 and the corresponding temperature control cavity 11. The polymer can enter the heat exchange tube 2 through the plurality of through holes, and the through holes also have a certain separation effect, reducing the agglomeration of the polymer.

[0063] In some or certain embodiments, one end of the heat exchange tube 2 may also be connected to the corresponding partition 16 , and the partition 16 is provided with a through hole correspondingly connected to each heat exchange tube 2 .

[0064] In some or certain embodiments, the heat exchange tube 2 extends along the axial direction of the cylinder 14, and the heat exchange container 1 further includes:

[0065] Two jackets 17 are connected to the corresponding heads 15 and a heating space 18 is formed between the jackets 17 and the heads 15 .

[0066] The two second heaters are connected to the corresponding jackets 17 and communicated with the corresponding heating spaces 18 so as to allow heat exchange medium to flow into the heating spaces 18 .

[0067] The jacket 17 mounted on the end cap 15 forms a heating space 18 with the end cap 15. The second heater can also adjust the temperature in the heating space 18 to change the temperature of the end cap 15. The end cap 15 exchanges heat with the air and other media in the insulation chamber, which can change the ambient temperature in the insulation chamber. On the basis of the heat exchange chamber 12, the jacket 17 and the second heater can adjust the temperature in the insulation chamber to change the temperature of the material entering the insulation chamber. The heat exchange tube 2 extends along the axial direction of the cylinder 14, so the polymer material with a lower temperature near the center of the insulation chamber can enter the heat exchange tube 2 first, and the material with a higher temperature in contact with the inner circumferential wall of the end cap 15 can be insulated by the end cap 15 and the second heater. The temperature of the polymer in the insulation chamber can be controlled to be more uniform as a whole, so that the material entering the heat exchange tube 2 is evenly heated and the temperature is more uniform. The polymer material flowing out of the heat exchange tube 2 to another insulation chamber can also be effectively controlled in temperature, which is also conducive to improving the temperature uniformity of the polymer.

[0068] In some or certain embodiments, the heat exchange cavity 12 is a cylindrical cavity, the two temperature control cavities 11 are located at the axial ends of the heat exchange cavity 12, and the heat exchange container 1 further includes:

[0069] The baffles 19 are spaced apart along the axial direction of the heat exchange chamber 12 and connected to the chamber wall of the heat exchange chamber 12 .

[0070] A plurality of support rods 20 extend at intervals along the axial direction of the heat exchange chamber 12 and are connected to a plurality of baffles 19 .

[0071] The baffles 19 and the support rods 20 also increase the flow of the heat exchange medium and improve the heat exchange efficiency.

[0072] In some or certain embodiments, the heat exchange tube 2 extends along the axial direction of the heat exchange cavity 12, and the heat exchange tube 2 passes through a plurality of baffles 19, which can improve the use stability of the heat exchange tube 2.

[0073] In some or certain embodiments, when the heat exchange cavity 12 is a cylindrical cavity, the heat exchange cavity 12 may be the space between the cylinder 14 and the partition 16 that is closed and connected at both ends of the cylinder 14. The outer peripheral wall of the cylinder 14 may be provided with at least two heat exchange medium inlets and outlets 141 spaced along the axial direction of the cylinder 14. The heat exchange medium inlets and outlets 141 may be openings provided by the cylinder 14 itself, or may be pipe openings of a pipe connected to the cylinder 14. The heat exchange medium inlets and outlets 141 are all connected to the heat exchange cavity 12. The first heater 3 may be connected to the heat exchange cavity 12 through at least two heat exchange medium inlets and outlets 141. The axial ends of the outer peripheral wall of the cylinder 14 may also be provided with exhaust ports 142 and exhaust ports 143 that are connected to the heat exchange cavity 12. This facilitates the flow in and out of the heat exchange medium. The outer peripheral wall of the cylinder 14 may also be provided with support ears 144 to facilitate the support and installation of the heat exchange container 1.

[0074] It should be noted that the second heater (not shown) and the jacket 17 can also be connected through a space inlet and outlet similar to the heat exchange medium inlet and outlet 141, which will not be described in detail here. The second heater and the first heater 3 can be set to the same type of equipment, such as a heat exchange tube 2 equipped with a delivery pump, etc., or the second heater and the first heater 3 can be set to heating equipment with different structures. Both can achieve the heating function.
