Description

Technical Field

[0001] The present invention relates to the technical field of reactor equipment, and specifically to a fixing device for a pH detection rod of a reactor. Background Art

[0002] A reactor is a container used in the chemical industry to complete processes such as mixing and reacting substances. For example, in the production process of resin, raw materials need to be put into the reactor for chemical reactions. During the reaction process, it is necessary to manually detect and control the pH value inside the reactor to ensure the quality of the resulting product.

[0003] The detection of the pH value inside the reactor is usually completed by a detection rod. The detection rod is inserted from the top of the reactor and fixed through a flange. However, when the length of the detection rod is too long and its detection depth is greater than the internal volume depth of the reactor, the detection rod inserted from the flange opening at the top of the reactor cannot be fixed on the reactor, resulting in a mismatch between the reactor and the detection rod. Customizing the detection rod separately affects work efficiency and is time-consuming and laborious.

[0004] Therefore, we have developed a fixing device for the detection rod. By designing a clamping head on the flange that can be manually adjusted in tightness, the clamping of the detection rod is achieved, enabling the flexible adjustment of the length of the detection rod inside the reactor, improving the disassembly and assembly speed of the detection rod, and enhancing work efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a fixing device for a pH detection rod of a reactor to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: A fixing device for a pH detection rod of a reactor includes a pressing flange. A first raised ring is provided at the upper end of the pressing flange. A plurality of pressing plates with inclined outer surfaces are evenly arranged at the upper end of the first raised ring. A broken circular pressing ring is detachably arranged inside the pressing plates. A locking nut is threadedly connected to the outside of the pressing plates for pressing the pressing plates inward.

[0007] As a further preferred solution of the present invention: A sealing flange is fixedly arranged at the lower end of the pressing flange. A second raised ring is provided on the sealing flange. The second raised ring is inserted into the first raised ring. A plurality of sealing ring placement grooves are formed in the inner circle of the sealing flange, and sealing rings are arranged in the sealing ring placement grooves.

[0008] As a still further preferred solution of the present invention: Corresponding taper threads are provided on the outer surface of the pressing plates and the inner surface of the locking nuts.

[0009] As a further preferred solution of the present invention: a baffle is provided at the bottom inside the pressing plate, a disconnected retaining ring is fixedly provided at the upper part inside the clamping plate, and the pressing ring is located between the baffle and the retaining ring.

[0010] As a further preferred solution of the present invention: a retaining ring placement groove for placing the retaining ring is provided on the pressing plate.

[0011] As a further preferred solution of the present invention: a tightening handle is fixedly provided on the outer surface of the locking nut.

[0012] As a further preferred solution of the present invention: three sealing ring placement grooves are evenly provided.

[0013] Compared with the prior art, the beneficial effects of the present invention are: Through the cooperation of the locking nut, the pressing plate and the pressing ring, by rotating the locking nut, the tightness of the pressing ring can be adjusted, and the adjustment and fixation of the detection rod can be easily achieved. Just fix the pressing flange to the corresponding mounting flange on the reaction kettle, pass the detection rod through the pressing flange, and after reaching the insertion depth of the detection rod, tighten the locking nut to achieve fixation. The operation is convenient, enabling the relatively long detection rod to match different models of reaction kettles, improving the flexibility of assembly. At the same time, the disassembly and assembly of the detection rod can be easily achieved by rotating the locking nut, improving the disassembly and assembly efficiency of the detection rod; By designing the sealing flange and providing multiple sealing rings inside the sealing flange, it can effectively prevent external dust from entering the reaction kettle through the gap between the detection rod and the flange, and can also prevent gases, vapors or water generated by the reaction inside the reaction kettle from escaping through the gap between the detection rod and the flange, ensuring the sealing effect. Moreover, the sealing flange and the pressing flange are connected in a plug-in manner, which is convenient for assembly; By providing a pressing plate and a detachable retaining ring inside the pressing plate, the detachable setting of the pressing ring is realized, which is convenient for replacing the pressing ring with a corresponding thickness according to the thickness of different detection rods to achieve the fixed assembly of different models of detection rods, improving the flexibility of use of the device; By providing a tightening handle on the pressing ring, the locking nut can be easily rotated by turning the tightening handle, which is convenient for realizing the disassembly and assembly of the detection rod and the operation is convenient.

[0014] In summary, the present invention can easily adjust the insertion depth of the detection rod in the reaction kettle, enabling the relatively long detection rod to match different models of reaction kettles, improving the flexibility of assembly. By adjusting the locking nut, the adjustment of the insertion depth of the detection rod and its disassembly and assembly operations can be easily achieved, improving the work efficiency.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Example

[0018] Please refer to Figure 1-4 , this embodiment provides a fixing device for the PH detection rod of a reactor, including a compression flange 1. A first raised ring 2 is provided at the upper end of the compression flange 1. A plurality of pressure plates 3 with inclined outer surfaces are evenly arranged at the upper end of the first raised ring 2. As Figure 3 shown, the plurality of pressure plates 3 form a conical ring. The outer surface of the pressure plate 3 is provided with a conical thread with a pitch preferably of 1.5 mm. A disconnectable circular pressure ring 5 is detachably arranged inside the pressure plate 3. In this embodiment, in order to facilitate the disassembly and assembly of the pressure ring 5, a baffle 32 is provided at the bottom inside the pressure plate 3 to support the pressure ring 5. A snap ring placement groove 31 is provided at the upper part inside the pressure plate 3, and a disconnectable snap ring 4 is placed in the snap ring placement groove 31. The pressure ring 5 is located between the baffle 32 and the snap ring 4 to realize the limit fixation of the pressure ring 5. The disconnectable design of the pressure ring 5 and the snap ring 4 ensures that when the pressure plate 3 is pressed inward, the pressure ring 5 and the snap ring 4 can contract and press inward along with the pressure plate 3. In order to adjust the tightness of the pressure plate 3, a locking nut 6 is sleeved outside the pressure plate 3, and its inner surface is also provided with a conical thread with a pitch of 1.5 mm to realize the threaded connection with the pressure plate 3.

[0019] Combined with Figure 1 and Figure 4 As shown, in order to achieve the sealing performance after the assembly of the detection rod 13, a sealing flange 7 is fixedly arranged at the lower end of the compression flange 1. A second raised ring 8 is arranged on the sealing flange 7, and the second raised ring 8 is inserted into the first raised ring 2. Three seal ring placement grooves 9 are evenly arranged in the inner circle of the sealing flange 7, and seal rings are arranged in the seal ring placement grooves 9.

[0020] In addition, combined with Figure 6 As shown, in order to facilitate the rotation of the locking nut 6, a tightening handle 14 is welded on the outer surface of the locking nut 6.

[0021] It should be noted that, as a conventional design familiar to those skilled in the art, mounting holes 10 are provided on the circumferences of the flange plates of the compression flange 1 and the sealing flange 7 for realizing the installation of the flange.

[0022] In order to enable those skilled in the art to better understand this detection rod fixing device, its assembly method will be described below: Combined with Figure 5 As shown, first, the compression flange 1 and the sealing flange 7 are assembled, and then they are fixed to the mounting flange 11 at the top of the reaction kettle through bolts. The detection rod 13 is sequentially passed through this detection rod fixing device and the mounting flange 11, and then inserted into the reaction kettle. When the detection rod 13 is inserted to a certain depth, the locking nut 6 is rotated, so that the pressure plate 3 drives the pressure ring 5 to tightly press and fix the detection rod 13, realizing the assembly of the detection rod 13; When disassembling, only need to loosen the locking nut 6, and then pull out the detection rod 13 upward.

[0023] It should be noted that in actual application, usually a sleeve 12 located inside the reaction kettle is arranged at the lower end of the mounting flange 11, which plays a role in stably limiting the detection rod 13. Therefore, when the detection rod 13 is actually installed, it will sequentially penetrate through the flange at the top of the reaction kettle and the internal sleeve 12. The design of the sleeve 12 is a conventional setting familiar to those skilled in the art and will not be elaborated here.
