[0032] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0034] Reference Figure 1FIG. 1 shows a related reactor, which includes a reactor body 300 and a reactor head 200. Currently, a stirring device is typically mounted on the reactor head 200 via a stirring flange. The stirring flange is used to bear the weight of the stirring device. At the same time, the interior of the stirring device is in contact with the material in the reactor and is used to bear the internal pressure of the reactor. The stirring device typically includes a drive mechanism and a stirring shaft. The drive mechanism is connected to the stirring shaft and drives the stirring shaft to rotate, thereby stirring the material in the reactor. The drive mechanism includes a motor, a reducer, and the like.

[0035] After extensive research, the inventors discovered that most current stirring flanges are integral forgings, integrally embedded within the opening 210 of the reactor head 200 to withstand the reactor's internal pressure. To withstand the high pressure inside the reactor, the stirring flange must be relatively thick, resulting in significant weight and high production costs.

[0036] Based on this, the present application provides a stirring flange to solve the above technical problems, with specific reference to the following embodiments.

[0037] Reference Figure 2-4 As shown, an embodiment of the present application discloses a stirring flange 100, including an inner flange 110 and an outer flange 120. The inner flange 110 is used to be at least partially embedded in the opening 210 on the reactor head 200. The inner flange 110 is provided with a first connecting surface 111 for connecting to the hole wall of the opening 210 in the circumference. The outer flange 120 is arranged around the inner flange 110, and the bottom of the outer flange 120 is provided with a second connecting surface 121 for connecting to the outer surface of the reactor head 200.

[0038] The stirring flange 100 provided in this embodiment adopts a split design of an inner flange 110 and an outer flange 120. The inner flange 110 is used to contact the material in the reactor and to bear the internal pressure of the reactor, and the outer flange 120 is used to bear the weight of the stirring device. This split design is beneficial to reducing the overall thickness and weight of the stirring flange 100 and reducing production costs.

[0039] Specifically, the inner flange 110 is provided with a through-hole 115 for the stirring shaft of the stirring device to pass through. The bottom surface of the inner flange 110 and the inner wall of the through-hole 115 are used to contact the materials in the reactor and to bear the internal pressure of the reactor. Due to the separate design of the inner flange 110 and the outer flange 120, the diameter of the inner flange 110 in this embodiment is smaller than that of a one-piece stirring flange. Therefore, while meeting the same strength requirements, the thickness of the inner flange 110 in this embodiment can be made smaller, thereby reducing the overall weight of the stirring flange 100. The reactor head 200 also has structures such as a feed port.

[0040] It should be noted that the diameter of the inner flange 110 in this embodiment is smaller than the diameter of the integrated stirring flange. Accordingly, the diameter of the opening 210 on the reactor head 200 corresponding to the stirring flange 100 in this embodiment is smaller than the diameter of the opening 210 on the reactor head 200 corresponding to the integrated stirring flange.

[0041] Furthermore, the reactor generally includes an upper head and a lower head, and the stirring device is installed on the upper head. Therefore, the reactor head 200 in this embodiment refers to the upper head.

[0042] In one embodiment, because inner flange 110 needs to contact the reactor contents, the material of inner flange 110 needs to be the same as the reactor's material, typically a high-strength and relatively high-cost material. However, outer flange 120, which does not contact the reactor contents, can be made of a different material and can be made of a high-strength, but relatively low-cost material, thereby reducing material costs. In other embodiments, the material of outer flange 120 can be the same as that of inner flange 110, without further limitation.

[0043] Preferably, both the inner flange 110 and the outer flange 120 are annular forgings to ensure structural strength. Furthermore, the first connecting surface 111 is welded to the wall of the opening 210, and the second connecting surface 121 is welded to the outer surface of the reactor head 200, further ensuring structural strength. Both the first connecting surface 111 and the second connecting surface 121 are annular. Since the outer surface of the reactor head 200 is typically a curved surface, the first connecting surface 111 is also a curved surface, further ensuring structural strength.

[0044] Furthermore, since the outer flange 120 has a larger contact area with the stirring device, it can bear more weight. Preferably, the inner and outer diameter difference of the outer flange 120 is greater than the inner and outer diameter difference of the inner flange 110 to ensure that the structural strength of the outer flange 120 is large enough to bear the stirring device.

[0045] Reference Figure 4 As shown, in one embodiment, a gap is provided between the inner flange 110 and the outer flange 120. The mixing flange 100 further includes a connecting member 130, which is disposed in the gap between the inner flange 110 and the outer flange 120. The inner flange 110 and the outer flange 120 are connected via the connecting member 130. The inner flange 110 and the outer flange 120 are connected via the connecting member 130, thereby improving the structural stability of the inner flange 110 and the outer flange 120, thereby improving the overall strength and load-bearing capacity of the mixing flange 100.

[0046] In one embodiment, multiple connectors 130 are provided, and the multiple connectors 130 are spaced apart along the circumference of the inner flange 110. The spaced-apart arrangement of multiple connectors 130 along the circumference of the inner flange 110 can further enhance the structural stability and overall strength of the inner and outer flanges 110, 120. Preferably, the connectors 130 include connecting ribs, one end of which is welded to the inner flange 110 and the other end to the outer flange 120. In another embodiment, the connectors 130 can be formed of connecting ribs, etc., without limitation.

[0047] Please continue to refer to Figure 3 As shown, in one embodiment, the inner flange 110 includes a first portion 112 for being embedded in the opening 210, and a second portion 113 arranged outside the opening 210. The first portion 112 is provided with a first connecting surface 111 in the circumference, and the second portion 113 is connected to the connecting member 130.

[0048] In one embodiment, the bottom of the connector 130 is provided with a third connecting surface 131 for connecting to the outer surface of the reactor head 200. The connector 130 is connected to the outer surface of the reactor head 200 across its entire surface, which helps enhance the overall strength and stability of the stirring flange 100. Furthermore, the third connecting surface 131 is welded to the outer surface of the reactor head 200. Similarly, since the outer surface of the reactor head 200 is typically a curved surface, the third connecting surface 131 is also a curved surface, further ensuring structural strength.

[0049] Please continue to refer to Figure 4 As shown, in one embodiment, the upper surface of the outer flange 120 and the upper surface of the inner flange 110 are both provided with mounting holes 114 for mounting the stirring device, so as to facilitate mounting the stirring device on the stirring flange 100. Furthermore, the mounting holes 114 are threaded holes, and the stirring device can be connected to the stirring flange 100 by bolts.

[0050] Please continue to refer to Figure 4 As shown, in one embodiment, the stirring flange 100 further includes a reinforcement member 140, one end of the reinforcement member 140 is connected to the outer flange 120, and the other end extends in a direction away from the outer flange 120, and the bottom of the reinforcement member 140 is provided with a fourth connecting surface 141 for connecting to the outer surface of the reactor head 200. Among them, the reinforcement member 140 can enhance the structural strength of the outer flange 120 and enhance its bearing capacity. Preferably, the reinforcement member 140 includes a reinforcing rib plate. In another embodiment, the reinforcement member 140 can select reinforcing ribs, etc., and there is no specific limitation. Similarly, since the outer surface of the reactor head 200 is usually a curved surface, correspondingly, the fourth connecting surface 141 is also a curved surface, further ensuring the structural strength.

[0051] Furthermore, a plurality of reinforcement members 140 are provided, and the plurality of reinforcement members 140 are arranged at intervals along the circumference of the outer flange 120 , which can further enhance the structural stability of the outer flange 120 and the overall structural strength.

[0052] Furthermore, in order to avoid affecting the installation of the stirring device, the upper surfaces of the reinforcing member 140 and the connecting member 130 are lower than the upper surfaces of the inner flange 110 and the outer flange 120 .

[0053] Please continue to refer to Figure 3 As shown, in one embodiment, the stirring flange 100 further includes a sealing cover plate 150, which is sealedly connected to the inner flange 110 and the outer flange 120 to form a sealed space between the inner flange 110 and the outer flange 120, thereby preventing foreign matter from entering the space between the inner flange 110 and the outer flange 120 and causing damage to the stirring flange 100 or the reactor head 200. Specifically, due to the presence of the multiple connectors 130, the inner flange 110 and the outer flange 120 are actually divided into multiple sealed spaces by the connectors 130.

[0054] Please continue to refer to Figure 3 As shown, in one embodiment, a drain hole 122 is provided on the outer flange 120, and a removable plug 160 is provided in the drain hole 122. The drain hole 122 is used for draining sewage to prevent sewage from accumulating between the inner flange 110 and the outer flange 120. The removable plug 160 can seal the drain hole 122 and can be removed regularly or irregularly to achieve sewage drainage.

[0055] Reference Figure 2 As shown, another embodiment of the present application discloses a reactor, which includes a reactor body 300 and a reactor head 200, wherein the reactor head 200 is arranged at the end of the reactor body 300; and the stirring flange 100 in the above embodiment, wherein the stirring flange 100 is installed on the reactor head 200.

[0056] Furthermore, the reactor further comprises a stirring device, which is mounted on the reactor head 200 via a stirring flange 100 .

[0057] The reactor provided in this embodiment has a stirring flange 100 that adopts a split design consisting of an inner flange 110 and an outer flange 120. The inner flange 110 is used to contact the material in the reactor and bear the internal pressure of the reactor, while the outer flange 120 is used to bear the weight of the stirring device. This split design helps reduce the overall thickness and weight of the stirring flange 100, thereby reducing production costs. This reduces the overall weight of the reactor and reduces production, transportation, and installation costs.
