Description

Technical Field

[0001] The present application relates to the technical field of chemical containers, and in particular to a feeding device and a reactor comprising the same. Background Art

[0002] At present, when using a reactor to carry out reaction operations, more liquid materials are added. Liquid materials are easier to control automatically, and the control of parameters such as flow rate is more precise.

[0003] However, in actual production, some materials are solid at room temperature and liquid at high temperatures. Therefore, when adding such materials, they need to be heated to a liquid state before being added to the reactor. However, due to the low freezing point of these materials, if the ambient temperature and the temperature inside the reactor are at room temperature or even lower than room temperature, the materials are prone to crystallization during the addition process, which can lead to blockage in the conveying pipeline. Therefore, when adding materials, the conveying pipeline needs to be heated or insulated to prevent the materials from solidifying. Utility Model Content

[0004] Typically, an insulation layer is installed on the outside of the conveying pipe to heat and keep the material inside. However, this insulation effect is still not obvious, causing the material to crystallize and adhere to the inner wall or outlet of the conveying pipe. This causes the actual amount of material added to the kettle to deviate from the target amount, affecting the reaction. Moreover, if too much material condenses in the conveying pipe, it will cause the pipe to become blocked and cannot be used normally.

[0005] Based on this, it is necessary to provide a feeding device that can effectively improve the insulation effect of the material, reduce the amount and risk of crystallization of the material in the feeding pipe, alleviate the blockage problem of the feeding pipe, ensure that the actual material amount meets the standard, and improve the reaction effect.

[0006] A feeding device comprises a feeding pipe, a jacketed pipe and a partition; the feeding pipe has a feeding end and a feeding end arranged opposite to each other along its own axial direction; the jacketed pipe is sleeved on the outside of the feeding pipe, a cavity is provided between the jacketed pipe and the feeding pipe, the jacketed pipe is provided with a liquid inlet and a liquid outlet communicating with the cavity, the liquid inlet and the liquid outlet are both arranged close to the feeding end; the partition is provided in the cavity and divides the cavity into a first cavity and a second cavity, the first cavity and the second cavity are connected, the first cavity is connected with the liquid inlet, and the second cavity is connected with the liquid outlet.

[0007] It can be understood that the heat transfer oil flows into the first cavity through the liquid inlet, then flows through the second cavity, and flows out from the liquid outlet. Since the first cavity and the second cavity are both located on the outside of the feeding pipe, it can be ensured that the heat transfer oil is in full contact with the feeding pipe to achieve heating and heat preservation effects, thereby reducing the amount of condensation of materials in the feeding pipe. In this process, it is precisely because the liquid inlet and the liquid outlet are both located at one end of the jacketed pipe close to the feeding end that when the heat transfer oil enters from the liquid inlet, it will have a tendency to flow toward the feeding end under the action of its own gravity, and then as the heat transfer oil is added, it accumulates in the second cavity, causing the heat transfer oil to gradually flow upward to flow out from the liquid outlet, which not only increases the contact area, but also increases the contact time, effectively improving the heating and heat preservation effects. Moreover, with the setting of the partition, the flow direction of the heat transfer oil in the cavity can be changed, the contact area between the heat transfer oil and the feeding pipe can be increased, and the heat transfer effect can be improved. In addition, it is precisely because of the position setting of the liquid inlet and liquid outlet that the feeding end of the feeding pipe can be extended into the kettle body, ensuring that the material is directly fed into the kettle body, reducing the material adhering to the inner wall of the kettle body, improving the feeding accuracy, and facilitating the subsequent cleaning of the kettle body.

[0008] In some embodiments, the first cavity and the second cavity are arranged along the circumference of the feeding pipe.

[0009] In some embodiments, the partition is provided with a through hole, and / or, a through hole is provided between the partition and the outer tube wall of the feeding pipe, and / or, a through hole is provided between the partition and the inner tube wall of the jacketed pipe; or, the partition, the outer tube wall of the feeding pipe and the inner tube wall of the jacketed pipe are jointly surrounded by a through hole; the first cavity and the second cavity are connected through the through hole.

[0010] In some embodiments, the via hole is provided near the feeding end.

[0011] In some embodiments, the cavity is arranged around the feeding pipe; two partitions are provided, and the two partitions are arranged at intervals along the circumference of the feeding pipe to separate the cavity into the first cavity and the second cavity.

[0012] In some embodiments, a plurality of partitions are provided and are arranged at intervals along the circumference of the feeding pipe to divide the cavity into a plurality of sub-cavities; among the plurality of sub-cavities, some are defined as the first cavity to connect to the liquid inlet, and the other part is defined as the second cavity to connect to the liquid outlet.

[0013] In some embodiments, the partitions are provided in plurality and are divided into connecting partitions and separating partitions, which are staggered along the circumference of the feeding pipe. A connecting partition is provided between any two adjacent separating partitions, and the connecting partition separates the cavity between the corresponding two separating partitions into the first cavity and the second cavity.

[0014] In some embodiments, along the axial direction of the feeding pipe, the liquid outlet is located between the liquid inlet and the feeding end.

[0015] In some embodiments, the feeding device further includes a first end plate, which is connected between the jacket tube and the feeding pipe and is close to the feeding end of the feeding pipe.

[0016] In some embodiments, the feeding device further includes a second end plate, which is connected between the jacket tube and the feeding pipe and is close to the feeding end of the feeding pipe.

[0017] In some embodiments, the feeding device further includes a connecting piece, and the connecting piece is provided at the feeding end of the feeding pipe.

[0018] In some embodiments, the connecting member is provided with a through hole, and the through hole is communicated with the feeding pipe.

DETAILED DESCRIPTION

[0033] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0034] It should be noted that when a component is referred to as being "fixed to" or "provided on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of this application are for illustrative purposes only and do not represent the only implementation method.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0036] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it can mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is higher in level than the second feature. When a first feature is "below," "below," or "below" a second feature, it can mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is lower in level than the second feature.

[0037] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0038] In related technologies, the outside of the conveying pipe is wrapped with an insulation layer, and a heat-conducting fluid is injected into the insulation layer to heat and insulate the material in the conveying pipe, thereby alleviating solidification of the material during the feeding process. The heat-conducting fluid injected into the insulation layer needs to be discharged from the insulation layer after heating, and in particular, it must not come into contact with the material in the kettle. Therefore, the injection and discharge ports of the insulation layer need to be located outside the kettle. In addition, the injection port is generally located at the bottom of the insulation layer to ensure sufficient contact area between the heat-conducting fluid and the conveying pipe. This makes the length of the conveying pipe outside the kettle much longer than the length extending into the kettle.

[0039] However, the reaction temperature in the kettle is not always high, and not all reactions require high temperatures. Therefore, when the temperature in the kettle is low or room temperature, the conveying pipe near the outlet is easily affected by the kettle temperature, causing the material to condense at the outlet of the conveying pipe and adhere to the inner wall of the conveying pipe or near the outlet, resulting in a deviation between the actual amount of material added to the kettle and the target amount of material, affecting the reaction quality. Moreover, if too much material condenses at the outlet of the conveying pipe, causing the pipe to be blocked, the material cannot be added normally. At the same time, it is precisely because the length of the conveying pipe extending into the kettle is very short that the distance between the conveying pipe and the material in the kettle is too large, causing the material to splash or float onto the stirring paddle or the kettle wall in the kettle, resulting in inaccurate feeding and difficulty in spraying and flushing.

[0040] Based on the above problems, an embodiment of the present application provides a feeding device, which, on the one hand, can effectively improve the insulation effect of the material, reduce the amount and risk of crystallization of the material in the feeding pipe, and alleviate the blockage problem of the feeding pipe; on the other hand, it can extend the length of the feeding device inserted into the kettle body, reduce the distance from the material in the kettle body, and thereby reduce the material adhering to the kettle wall or the stirring paddle, thereby improving the feeding accuracy and facilitating subsequent cleaning.

[0041] The feeding device is described in detail below.

[0042] See also Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 11 Exemplarily, the feeding device 100 includes a feeding pipe 110, a jacketed pipe 120, and a partition 130. The feeding pipe 110 has a feeding end 111 and a feeding end 112 arranged opposite to each other along its own axial direction. The jacketed pipe 120 is sleeved on the outside of the feeding pipe 110, and a cavity 101 is provided between the jacketed pipe 120 and the feeding pipe 110. The partition 130 is provided in the cavity 101 and divides the cavity 101 into a first cavity 1011 and a second cavity 1012. The jacketed pipe 120 is provided with a liquid inlet 121 and a liquid outlet 122 communicating with the cavity 101, and both the liquid inlet 121 and the liquid outlet 122 are arranged near the feeding end 112. The aforementioned first cavity 1011 is communicated with the liquid inlet 121, and the aforementioned second cavity 1012 is communicated with the liquid outlet 122.

[0043] It should be noted that the feeding end 112 is the end for adding material to the feeding pipe 110, and the feeding end 111 is the end that extends into the kettle body 200 and directly feeds material into the kettle body 200. The material falls from the feeding end 112 to the feeding end 111 under its own gravity, and then falls into the material in the kettle body 200 from the feeding end 111.

[0044] In this embodiment, the heat transfer oil flows into the first cavity 1011 through the liquid inlet 121, then flows through the second cavity 1012, and flows out through the liquid outlet 122. Because the first cavity 1011 and the second cavity 1012 are both located outside the feeding pipe 110, the heat transfer oil can be ensured to fully contact the feeding pipe 110, thereby achieving a heating and heat preservation effect and reducing the amount of condensation of the material in the feeding pipe 110. Since the liquid inlet 121 and the liquid outlet 122 are both located at one end of the jacket tube 120 near the feeding end 112, when the heat transfer oil enters from the liquid inlet 121, it will have a tendency to flow toward the feeding end 111 under the action of its own gravity, and then accumulate in the second cavity 1012 as the heat transfer oil is gradually added, so that the heat transfer oil gradually gathers upward to flow out from the liquid outlet 122; then, a hydraulic pump can be used to drive the heat transfer oil to flow into the first cavity 1011 through the liquid inlet 121, and then flow through the second cavity 1012, and then flow out from the liquid outlet 122 to achieve the purpose of heating and heat preservation. Such a setting not only increases the contact area between the heat transfer oil and the feeding pipe 110, but also increases the contact time, which is conducive to effectively improving the heating and heat preservation effect; and, in this process, in conjunction with the setting of the partition 130, the flow direction of the heat transfer oil in the cavity 101 can be changed, effectively increasing the contact area between the heat transfer oil and the feeding pipe 110, and further improving the heat transfer effect. If the partition 130 is not provided, the heat transfer oil will directly flow in from the liquid inlet 121 and out from the liquid outlet 122 , so that the feeding end of the feeding pipe 110 cannot be effectively heated.

[0045] Therefore, the feeding device provided in this embodiment can extend the entire area of ​​the feeding pipe 110 below the feeding end 112 into the kettle body 200 as much as possible. Combined with the flow of the above-mentioned oil, the feeding pipe 110 inserted into the kettle body 200 can be fully heated and insulated, alleviating the problem of material condensation in the feeding pipe 110 due to the influence of low temperature or normal temperature in the kettle body 200, and reducing the deviation between the actual amount of material fed and the target amount of material. Moreover, such a setting can reduce the distance between the feeding end 111 and the material in the kettle body 200, ensuring that the material can be directly fed into the material in the kettle body 200 as much as possible, alleviating the problem of the material floating and adhering to the kettle wall or the stirring paddle due to the large distance, and improving the feeding accuracy. In this way, it is not only beneficial to improve the reaction quality, but also convenient for the subsequent spray cleaning in the kettle body 200.

[0046] like Figure 3 and Figure 8As shown, in actual use, the partition 130 is provided with a through hole 1301, which is arranged along the thickness direction of the partition 130 to connect the first cavity 1011 and the second cavity 1012, facilitating the flow of heat transfer oil to heat and keep the feeding pipe 110. There can be one through hole 1301, or multiple through holes 1301 can be provided and arranged at intervals, as long as they meet the requirements of the flow of heat transfer oil from the first cavity 1011 to the second cavity 1012. The through holes 1301 can also be round holes, square holes, triangular holes, or even hexagonal holes.

[0047] Alternatively, a through hole 1301 may be provided between the partition 130 and the outer wall of the feeding tube 110 to ensure fluid communication between the first cavity 1011 and the second cavity 1012. In this case, a notch may be provided on the outer wall of the feeding tube 110, and a notch may also be provided at a corresponding position on the partition 130, extending through the thickness of the partition 130. The two corresponding notches together form the through hole 1301. Alternatively, a U-shaped notch may be provided only at the position of the partition 130 facing the feeding tube 110, and the U-shaped notch and the outer wall of the feeding tube 110 may together form the through hole 1301. Of course, a V-shaped notch may also be provided on the partition 130.

[0048] Alternatively, a through hole 1301 is provided between the partition 130 and the inner tube wall of the jacket tube 120 , which is formed in a manner similar to the through hole 1301 between the partition 130 and the feeding tube 110 , and thus will not be described in detail.

[0049] Alternatively, the partition 130, the outer wall of the feeding pipe 110, and the inner wall of the jacketed pipe 120 may all define a through hole 1301. In other words, the end of the partition 130 facing the feeding end 111 does not directly abut the bottom of the cavity 101, but rather leaves a gap therebetween to serve as the through hole 1301 for the flow of heat transfer oil.

[0050] like Figure 1 and Figure 3 As shown, in some specific embodiments, the through hole 1301 is arranged near the feeding end 111. Such an arrangement can ensure that the heat transfer oil flowing into the first cavity 1011 through the liquid inlet 121 flows fully downward, ensuring a large contact area with the feeding pipe 110 in the axial direction, so that the portion of the feeding pipe 110 extending into the kettle body can be fully heated.

[0051] When there are multiple through holes 1301 , they may be arranged at intervals along the axial direction of the feeding pipe 110 .

[0052] like Figure 1As shown, further, along the axial direction of the feeding pipe 110, the liquid outlet 122 is located between the liquid inlet 121 and the feeding end 111. That is to say, when the axial direction of the feeding pipe 110 is vertical, the liquid outlet 122 is located below the liquid inlet 121. Such an arrangement allows the heat transfer oil to flow through the liquid outlet 122 preferentially when it converges toward the liquid outlet 122, rather than flowing back from the liquid inlet 121. Alternatively, along the axial direction of the feeding pipe 110, the liquid outlet 122 is parallel to the liquid inlet 121, so that the heat transfer oil can flow through the entire jacket tube 120, thereby ensuring the heat exchange effect. Alternatively, along the axial direction of the feeding pipe 110, the liquid inlet 121 is located between the liquid outlet 122 and the feeding end 111.

[0053] like Figure 3 and Figure 4 As shown, a partition 130 is connected between the feeding pipe 110 and the jacket pipe 120. One side of the partition 130 along the width direction is fixed to the outer wall of the feeding pipe 110, and the other side is fixed to the inner wall of the jacket pipe 120, thereby separating the cavity 101. The length of the partition 130 extends along the axial direction of the feeding pipe 110, and the width of the partition 130 extends along the radial direction of the feeding pipe 110. Of course, the width direction of the partition 130 can also be arranged at an angle to the radial direction of the feeding pipe 110.

[0054] Alternatively, the jacket tube 120 may be a plurality of arc-shaped petals spliced ​​along the circumference of the feeding tube 110, a partition 130 may be provided between two adjacent arc-shaped petals, and both arc-shaped petals are fixed to the partition 130, for example, by bonding or welding.

[0055] like Figure 4 As shown, in some embodiments, when the jacket tube 120 is sleeved on the outside of the feeding tube 110, the outer wall of the feeding tube 110 and the inner wall of the jacket tube 120 do not contact each other, thereby forming a cavity 101 annularly disposed on the feeding tube 110. In this case, two partitions 130 may be provided in the cavity 101. The two partitions 130 are spaced apart along the circumference of the feeding tube 110 to separate the annular cavity 101 into two arc-shaped cavities, namely, a first cavity 1011 and a second cavity 1012.

[0056] like Figure 5 Alternatively, a portion of the outer wall of the feeding pipe 110 contacts a portion of the inner wall of the jacket pipe 120, thereby forming a crescent-shaped cavity 101 outside the feeding pipe 110. In this case, a partition 130 can be provided in the cavity 101 to separate it into a first cavity 1011 and a second cavity 1012.

[0057] That is to say, the first cavity 1011 and the second cavity 1012 are arranged along the circumference of the feeding pipe 110, which can ensure that there is a flow path of heat transfer oil corresponding to the circumference of the feeding pipe 110 itself, further increasing the contact area and improving the heating and insulation effects.

[0058] Alternatively, the first cavity 1011 and the second cavity 1012 may also be arranged in a V-shape, as long as they can ensure sufficient contact area with the feeding pipe 110 and improve the heating and heat preservation effects, which is only illustrated here as an example.

[0059] like Figure 1 and Figure 6 As shown, in another embodiment, a third cavity 1013 and a fourth cavity 1014 are further separated between the first cavity 1011 and the second cavity 1012, and the two are connected. The third cavity 1013 is connected to the first cavity 1011, and the fourth cavity 1014 is connected to the second cavity 1012. In this case, the partition 130 includes a partitioning partition 133 and three connecting partitions 132, which are arranged at intervals along the circumference of the feeding pipe 110. The first cavity 1011 and the second cavity 1012 are respectively arranged on both sides of the thickness direction of the partitioning partition 133. The three connecting partitions 132 are arranged between the first cavity 1011 and the second cavity 1012 to separate the third cavity 1013 and the fourth cavity 1014. Among them, the three connecting partitions 132 are all provided with through holes 1301.

[0060] The heat transfer oil enters the first cavity 1011 through the liquid inlet 121, flows downward, passes through the corresponding through-hole 1301, and enters the third cavity 1013. It gradually converges upward in the third cavity 1013 and passes through the corresponding through-hole 1301 to enter the fourth cavity 1014. In the fourth cavity 1014, it flows downward under its own gravity and enters the second cavity 1012. It then gradually converges upward in the second cavity 1012 to flow out through the liquid outlet 122. In this way, a circuitous flow path is formed, further improving the heating and heat preservation effects.

[0061] See also Figure 1 and Figure 7 In other embodiments, a plurality of partitions 130 may be provided, and arranged at intervals along the circumference of the feeding pipe 110 to divide the cavity 101 into a plurality of sub-cavities 101a. Among the multiple sub-cavities 101a, part is defined as the first cavity 1011 to connect to the liquid inlet 121, and the other part is defined as the second cavity 1012 to connect to the liquid outlet 122. In this way, the heat transfer oil flowing in through the liquid inlet 121 can be dispersed to a plurality of corresponding sub-cavities 101a, increasing the contact area with the feeding pipe 110, so that the feeding pipe 110 can fully withstand the high heat from the heat transfer oil. At the same time, when the heat transfer oil is discharged, it can be gathered to the liquid outlet 122, and there is no need to provide a separate liquid outlet 122 for each sub-cavity 101a, thereby simplifying the structure.

[0062] Wherein, a guide plate can be arranged between each corresponding plurality of sub-cavities 101a forming the first cavity 1011 at the liquid inlet 121 to guide the flow of oil. At the same time, a guide plate can also be arranged between each corresponding plurality of sub-cavities 101a forming the second cavity 1012 at the liquid outlet 122 to guide the flow of oil.

[0063] As shown in Figure 1 and Figure 7 , in some embodiments, among the plurality of partitions 130, two partitions 130 are arranged opposite and spaced along the radial direction of the feeding pipe 110, and a through hole 1301 is arranged at the position of the partition 130 close to the feeding end 111 of the feeding pipe 110, and the two partitions 130 separate the first cavity 1011 and the second cavity 1012 opposite in the radial direction. The first cavity 1011 and the second cavity 1012 are respectively provided with two spaced partitions 130, and each partition 130 is provided with a plurality of through holes 1301 arranged axially along the feeding pipe 110.

[0064] As shown in Figure 1 and Figure 8 , in yet other embodiments, the partition 130 includes a plurality of communication partitions 132 and a plurality of separation partitions 133, the plurality of communication partitions 132 and the plurality of separation partitions 133 are spaced and staggered along the circumferential direction of the feeding pipe 110, and there is a communication partition 132 between any two adjacent separation partitions 133, and the communication partition 132 separates the cavity between the corresponding two separation partitions 133 into the first cavity 1011 and the second cavity 1012. Wherein, each group of first cavities 1011 and second cavities 1012 corresponds to a group of liquid inlets 121 and liquid outlets 122. In this way, multiple liquid inlets 121 can be used to inject heat-conducting oil at the same time, improving the heat transfer efficiency.

[0065] It should be noted that the communication partition 132 refers to a partition that is provided with a through hole 1301 for the heat-conducting oil to pass through on the basis of separating the space; the separation partition 133 refers to a partition that is only used for space separation and cannot be used for the heat-conducting oil to pass through.

[0066] Please refer to Figure 1 , Figure 3 , Figure 9 and Figure 10 , in optional embodiments, the feeding device 100 further comprises a first end plate 141 connected between the jacket pipe 120 and the feeding pipe 110, and close to the feeding end 111 of the feeding pipe 110. That is, the first end plate 141 is used to block the side of the cavity 101 facing the feeding end 111 to prevent the heat-conducting oil from falling into the kettle body.

[0067] Furthermore, the feeding device 100 also includes a second end plate 142, which is connected between the jacket tube 120 and the feeding pipe 110 and is close to the feeding end 112 of the feeding pipe 110. In other words, the second end plate 142 blocks the side of the cavity 101 facing the feeding end 112 to prevent the fed material from falling into the cavity 101, or foreign matter from falling into the cavity and affecting the flow of the heat transfer oil.

[0068] Among them, the first end plate 141 can be set at an angle. In this case, the feeding end 111 of the feeding pipe 110 protrudes compared to the jacket tube 120. At the same time, such a setting can make the partition 130, the outer tube wall of the feeding pipe 110, the inner tube wall of the jacket tube 120 and the first end plate 141 together form a through hole 1301 when the bottom of the partition 130 is flush, without the need to set a notch on the feeding pipe 110 and the jacket tube 120. At the same time, the first end plate 141 is set at an angle so that the feeding device 100 is set in a constricted shape at the feeding end 111, which is more conducive to the insertion of the feeding device 100 into the kettle body.

[0069] Furthermore, the first end plate 141 and the second end plate 142 can be integrally formed with the feeding pipe 110 and welded to the jacket pipe 120. Alternatively, they can be integrally formed with the jacket pipe 120 and welded to the feeding pipe 110. This is merely an example.

[0070] Alternatively, the first end plate 141 can also be arranged horizontally. Of course, the second end plate 142 can also be arranged at an angle or horizontally. Regardless of how the first end plate 141 and the second end plate 142 are arranged, they only need to achieve the blocking of the axial ends of the cavity 101.

[0071] Alternatively, the jacket tube 120 may be provided with radially inwardly projecting annular steps at both ends of its axial direction, with the inner walls of the annular steps contacting the outer wall of the feeding tube 110 and being welded to seal the axial ends of the cavity 101. In this case, the cavity 101 can be sealed without the need for the first end plate 141 and the second end plate 142.

[0072] See also Figure 1 and Figure 3 In another exemplary embodiment, the feeding device 100 further includes a connector 150 disposed at the feeding end 112 of the feeding pipe 110. The connector 150 is used to connect to other structures for feeding. The connector 150 may be a flange. In actual use, the connector 150 is provided with a through hole 151, which communicates with the feeding pipe 110. Specifically, the through hole 151 communicates with the lumen 113 of the feeding pipe 110, facilitating material addition.

[0073] Among them, the inner tube wall of the feeding pipe 110, the hole wall of the through hole 151 and the end surface of the connecting piece 150 away from the feeding pipe 110 are all provided with anti-corrosion coatings to reduce the corrosion effect of the material on the above three and extend the service life.

[0074] Of course, it is also possible that one of the three components mentioned above is provided with an anti-corrosion coating, or two of them are provided with an anti-corrosion coating. For example, only the inner wall of the feeding pipe 110 may be provided with an anti-corrosion coating, or only the wall of the through hole 151 may be provided with an anti-corrosion coating, or both the inner wall of the feeding pipe 110 and the wall of the through hole 151 may be provided with an anti-corrosion coating, or both the end surface of the connector 150 facing away from the feeding pipe 110 and the inner wall of the feeding pipe 110 may be provided with an anti-corrosion coating. These are merely examples.

[0075] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 11 Furthermore, the feeding device 100 also includes a fixing member 160, which is disposed on the jacket tube 120 and is used to connect to the kettle body 200. In other words, when the portion of the feeding device 100 located below the liquid inlet 121 and the liquid outlet 122 is inserted into the kettle body 200, the fixing member 160 can be connected to the kettle body 200, thereby improving the assembly reliability of the feeding device 100. The fixing member 160 can be a pressure plate or a flange disposed on the outside of the jacket tube 120.

[0076] The outer circumference of the jacket tube 120 between the fixing member 160 and the feeding end 111 is provided with an anti-corrosion coating, and the side wall of the fixing member 160 facing the feeding end 111 is also provided with an anti-corrosion coating. This reduces corrosion of the jacket tube 120 and the fixing member 160 by the material in the kettle body 200, thereby increasing their service life. Of course, the anti-corrosion coating may also be provided only on the jacket tube 120 or only on the fixing member 160.

[0077] It can be understood that the provision of the aforementioned anti-corrosion coating can not only reduce material corrosion, but also ensure a smooth surface and reduce material adhesion.

[0078] See also Figure 11 Another embodiment of the present application provides a reactor, comprising a reactor body 200 and the aforementioned feeding device 100. The feeding device 100 is disposed through the reactor body 200, with the feeding end 111 located inside the reactor body 200 and the feeding end 112 located outside the reactor body 200. An assembly hole for the feeding device 100 to pass through can be provided at the top of the reactor body 200, and a support member 210 can be installed at the assembly hole. The portion of the feeding device 100 near the feeding end 111 extends into the reactor body 200 through the assembly hole. The fixing member 160 thereon can be pressed against the side of the support member 210 facing away from the reactor body 200 and connected to the support member 210 to achieve assembly of the feeding device 100 relative to the reactor body 200.

[0079] The support 210 and the fixing member 160 can be detachably connected, such as threaded connection, snap fit, etc., facilitating disassembly, replacement and maintenance of the feeding device 100.

[0080] The technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.

[0081] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
