Description

Technical Field

[0001] This utility model relates to the field of reaction vessel jet ejector installation technology, and in particular to a reaction vessel structure that facilitates the installation and adjustment of jet ejectors. Background Technology

[0002] In the production process of new energy materials and other fields, precursors play a crucial role in the energy density and other indicators of power batteries. Precursor synthesis is carried out in a reactor. Nowadays, in some scenarios, jet injectors can be used to replace or assist traditional unidirectional stirring. Therefore, different material jet angles have different effects on stirring.

[0003] In the prior art, jet injectors are usually directly connected to the reactor wall via a mounting base. This greatly restricts the installation position of the jet injector, thereby limiting the jet angle. Furthermore, the mounting base holes match the jet injector pipe, making it impossible to adjust the angle and difficult to remove the jet injector, which is inconvenient for replacement and maintenance.

[0004] Therefore, it is necessary to propose a reactor structure that facilitates the installation and adjustment of the jet injector in order to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0005] The main objective of this invention is to provide a reactor structure that facilitates the installation and adjustment of jet injectors, thereby solving the problems of the inability to adjust the jet angle and flexibly replace jet injectors after installation in the prior art.

[0006] To achieve the above objectives, this utility model provides a reaction vessel structure that facilitates the installation and adjustment of the jet injector, including a reaction vessel body, a side injection device, and a bottom injection device; wherein,

[0007] The reactor body includes a vertical sidewall section and an arc-shaped bottom wall section. Both the side injection device and the bottom injection device include a flange seat, a positioning flange, a bend, and an injector. The flange seat of the side injection device is connected to the vertical sidewall section, and the flange seat of the bottom injection device is connected to the arc-shaped bottom wall section.

[0008] The positioning flange is rotatably arranged along its circumference and connected to the flange seat. Each flange seat on the reactor body has a corresponding through hole. The bend passes through the positioning flange and is connected to the positioning flange. The bent section of the bend passes through the through hole and extends into the reactor body. The injector is connected to the bent section of the bend.

[0009] Preferably, the flange seat has a conical chamber, and the large-diameter end of the conical chamber is located on the side close to the interior of the reactor body.

[0010] Preferably, the flange seat of the bottom injection device is arranged in an arc shape on the side near the interior of the reactor body, and the curvature of the arc side of the flange seat is consistent with the curvature of the arc-shaped bottom wall section where it is installed.

[0011] Preferably, the large-diameter end and the small-diameter end of the conical chamber of the flange seat are respectively provided with chamfers.

[0012] Preferably, it further includes a connecting flange for communicating with an external material pipe, wherein the straight section of the bend extends out of the positioning flange, and the connecting flange is connected to the end of the straight section of the bend.

[0013] Preferably, the positioning flange is detachably connected to the flange seat by bolts.

[0014] Preferably, a group of side spray devices arranged circumferentially along the reactor body constitutes a group of side spray device units, and the number of side spray device units is two groups, which are arranged vertically at intervals.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a reactor structure that facilitates the installation and adjustment of jet injectors. It includes a reactor body, a side-spraying device, and a bottom-spraying device. The reactor body includes a vertical sidewall section and an arc-shaped bottom wall section. Both the side-spraying device and the bottom-spraying device include a flange seat, a positioning flange, a bend, and an injector. The flange seat of the side-spraying device is connected to the vertical sidewall section, and the flange seat of the bottom-spraying device is connected to the arc-shaped bottom wall section.

[0034] Please see the appendix Figure 1-6 The present invention provides a reaction vessel structure that facilitates the installation and adjustment of the jet injector 240, comprising a reaction vessel body 10, a side injection device 20, and a bottom injection device 30, the specific details of which are as follows:

[0035] The reactor body 10 includes a vertical sidewall section 110 and an arc-shaped bottom wall section 120. The side spraying device 20 and the bottom spraying device 30 each include a flange seat 210, a positioning flange 220, a bend 230, and an injector 240. The flange seat 210 of the side spraying device 20 is connected to the vertical sidewall section 110, and the flange seat 210 of the bottom spraying device 30 is connected to the arc-shaped bottom wall section 120. The positioning flange 220 is rotatably arranged along its circumference and connected to the flange seat 210. Each flange seat 210 on the reactor body 10 has a corresponding through hole 130. The bend 230 passes through the positioning flange 220 and is connected to the positioning flange 220. The bent section of the bend 230 passes through the through hole 130 and extends into the reactor body 10. The injector 240 is connected to the bent section of the bend 230.

[0036] Specifically, the reactor structure for easy installation and adjustment of the jet injector 240 in this application includes a reactor body 10, a side injection device 20, and a bottom injection device 30. Typically, the reactor consists of a cylindrical body, an upper end cap, and a lower end cap. Therefore, the vertical side wall section 110 in this application is the cylindrical body, used for the installation and connection of the side injection device 20, while the arc-shaped bottom wall section 120 is the lower end cap section, used for the installation and connection of the bottom injection device 30, so as to spray materials into the reactor from the side and bottom from different angles and directions.

[0037] Both the side spraying device 20 and the bottom spraying device 30 include a flange seat 210, a positioning flange 220, a bend 230, and an injector 240. They employ a structure where the flange seat 210 and the positioning flange 220 cooperate with each other, replacing the traditional method of directly fixing the mounting base to the reactor. The bend 230 is directly connected to the positioning flange 220, with its bent section extending into the reactor to allow the injector 240 to extend into the reactor. Thus, adjusting the positioning flange 220 adjusts the bend 230. Specifically, the positioning flange 220 is rotatably mounted circumferentially. Each time the positioning flange 220 rotates a certain angle circumferentially, the bend 230 connected to it also rotates, changing the orientation of the bend and thus the orientation of the injector 240. The positioning flange 220 is bolted to the flange seat 210. The connection 10, as can be understood, typically has multiple bolt holes on the flange. After rotating axially until aligned with adjacent bolt holes, the orientation of the bend 230 is changed, and then the positioning flange 220 and flange seat 210 are fastened together with bolts. When further adjustment of the injection angle of the injector 240 is needed, only the bend 230 needs to be replaced, greatly facilitating the adjustment of the injector 240 angle. Therefore, it can be seen that this design achieves the separation of the injector 240's position and angle relative to the reactor from the flange seat 210. That is, the installation of the flange seat 210 does not affect the installation position and angle of the injector 240. The flange seat 210 can be arranged and adjusted according to the connection location to facilitate manufacturing and installation without affecting the arrangement of the injector 240's position and angle. Preferably, each flange seat 210 can be fixed to the reactor body 10 by welding, which is convenient for processing and ensures a tight connection.

[0038] In a preferred embodiment of the present invention, the flange seat 210 has a conical chamber 211, and the large-diameter end of the conical chamber 211 is located on one side close to the interior of the reactor body 10.

[0039] It should be noted that the conical chamber 211 expands the internal space of the flange seat 210, facilitating the insertion and installation of the bent pipe 230. Similarly, it also facilitates the disassembly and removal of the bent pipe 230 when replacing it. The large-diameter end of the conical chamber 211 is positioned closer to the interior of the reactor body 10, thus allowing for lining treatment of both the large-diameter and small-diameter ends of the conical chamber 211. Specifically, the flange seat 210 of the bottom injection device 30 is arc-shaped on the side closer to the interior of the reactor body 10, and... The curvature of the arc-shaped side of the flange seat 210 is consistent with the curvature of the arc-shaped bottom wall section 120 at its installation location. This allows for structural matching between the bottom flange seat 210 and the arc-shaped bottom wall section 120 through cutting and shaping, improving the continuity and sealing of the connection and maintaining good structural integrity. Furthermore, the large-diameter and small-diameter ends of the conical chamber 211 of the flange seat 210 are respectively chamfered. This chamfers the edges of the flange seat 210 that come into contact with the material, reducing the damage to the material caused by the sharpness of the edges. Please refer to the appendix for details. Figure 6 .

[0040] It is worth mentioning that the injector 240 can be connected to the bent section of the bend 230 by threaded sealing, which is stable and has good sealing performance. The combination of injector 240 and bend 230 can be disassembled and maintained when the material in the reactor is not submerged, and can be taken out through the conical inner cavity of flange seat 210.

[0041] In a preferred embodiment of the present invention, a connecting flange 250 for communicating with an external material pipe is also included. The straight section of the bend 230 extends out of the positioning flange 220, and the connecting flange 250 is connected to the end of the straight section of the bend 230.

[0042] It is worth noting that the connecting flange 250 facilitates the connection of the bend 230 to the external feeding mechanism, so as to ensure that the bend 230 is also convenient to connect at the material input end and has good sealing performance. Therefore, the straight section of the bend 230 extends out of the positioning flange 220 to facilitate the installation of the connecting flange 250.

[0043] Furthermore, multiple side spray devices 20 arranged circumferentially along the reactor body 10 constitute a group of side spray device 20 units, and there are two groups of side spray device 20 units, which are arranged vertically at intervals.

[0044] It should be understood that the number of the side spray device 20 units can be set according to the actual required mixing efficiency, and can also be determined comprehensively based on the liquid level, reactor height, etc. In a preferred embodiment of this application, the number of the side spray device 20 units is two sets, and those skilled in the art can select according to actual needs.

[0045] Furthermore, each of the side injection device 20 units contains four side injection devices 20, and the four side injection devices 20 are arranged at equal intervals along the circumference of the reactor body 10 at the vertical side wall section 110.

[0046] It should be noted that, similarly, the number of side spray devices 20 in each side spray device 20 unit can also be set according to the actual required mixing effect. Preferably, the number of side spray devices 20 in each side spray device 20 unit is four. Thus, in this application, by combining two side spray device 20 units, the total number of side spray devices 20 is eight.

[0047] Furthermore, the number of bottom spray devices 30 is eight, and the eight bottom spray devices 30 are arranged at equal intervals along the circumference of the reactor body 10 at the arc-shaped bottom wall section 120.

[0048] It should be noted that the number of bottom spray devices 30 can be set according to the space of the arc-shaped bottom wall section 120 and the desired mixing effect. Preferably, the number of bottom spray devices 30 is eight, but those skilled in the art can set it according to the actual situation.

[0049] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
