Description

Technical Field

[0001] This utility model relates to the field of pH monitoring equipment technology, and in particular to a pH monitoring device for the preparation of bromotriazine. Background Technology

[0002] Bromotriazine is white in appearance, has a large molecular weight and complex structure, and possesses good thermal stability and electrical properties, as well as excellent light resistance. Unlike traditional bromine-based flame retardants, bromotriazine has a high initial decomposition temperature. Furthermore, due to its endothermic decomposition and heat reduction mechanism, it does not contain free bromine. In the preparation process of bromotriazine, pH monitoring equipment plays a crucial role. This equipment can monitor the pH value of the reaction system in real time or continuously, thereby ensuring that the reaction proceeds under optimal acidic or alkaline conditions to improve product quality and yield. Currently, pH monitoring equipment used in the preparation of bromotriazine generally involves placing a pH probe inside the reaction vessel to detect the pH value of the slurry. However, the pH probe is easily adhered to by particulate matter, thus affecting the pH detection results. Utility Model Content

[0003] This invention provides a pH monitoring device for the preparation of bromotriazine, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

A connecting wire is provided on the surface of the controller, and a pH value detection probe is mounted on one end of the connecting wire. A connecting column is connected to the surface of the pH value detection probe.

[0007] The bottom of the cover and the bottom of the reactor interior are equipped with a filter barrel for protecting the pH detection probe.

[0008] As a further description of the above technical solution:

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Reference Figures 1-4 A pH monitoring device for the preparation of bromotriazine includes a reaction vessel 1, a cover 2 at the top of the reaction vessel 1, a motor 3 mounted on the top of the cover 2, a rotating rod 4 connected to the output end of the motor 3, a stirring rod 5 for stirring the bromotriazine raw material on the surface of the rotating rod 4, and cleaning blocks 6 on the upper and lower sides of the surface of the rotating rod 4; a mounting plate 7 with a "U"-shaped cross-section is provided on one side of the reaction vessel 1, a controller 8 is mounted on the surface of the mounting plate 7, and a connecting wire 9 is provided on the surface of the controller 8. A pH value detection probe 11 is installed at one end, and a connecting post 10 is connected to the surface of the pH value detection probe 11. A filter barrel 12 for protecting the pH value detection probe 11 is set at the bottom end of the cover 2 and the bottom end of the interior of the reactor 1. The pH value inside the reactor 1 can be detected by the two pH value detection probes 11 and displayed on the controller 8. The filter barrel 12 outside the pH value detection probe 11 can block particulate matter and prevent particulate matter from adhering to the surface of the pH value detection probe 11, thereby affecting its pH value detection results.

[0030] Furthermore, the two connecting posts 10 are threaded to the surface of the cover 2 and the reactor 1, and a sealing ring is provided at the connection between the connecting posts 10 and the cover 2 and the reactor 1. This is to facilitate the installation of the two pH value detection probes 11 inside the reactor 1 through the connecting posts 10 at the upper and lower ends. The sealing ring is used to seal the connection to prevent leakage.

[0031] Furthermore, the filter barrel 12 is rotatably connected to the cover 2 and the reactor 1. The cleaning block 6 is in contact with the surface of the filter barrel 12. This is so that when the cleaning block 6 moves on the surface of the filter barrel 12, it can not only clean the particles on the surface of the filter barrel 12, but also drive the filter barrel 12 to rotate, so as to clean the particles on different surfaces.

[0032] Furthermore, a fixing block 13 is provided at the top of the cover 2 and the bottom of the reactor 1, and a positioning hole is provided on the surface of the fixing block 13. A screw 14 is rotatably connected to the surface of the mounting plate 7, and a moving plate 15 is threadedly connected to the surface of the screw 14. A positioning rod 16 connected to the positioning hole is provided on the surface of the moving plate 15. By rotating the screw 14, the moving plates 15 on both sides of its surface can drive the positioning rod 16 to move within the slide groove 17 through the slider 18, so as to move the positioning rod 16 into the positioning hole. Thus, the mounting plate 7 and the controller 8 can be installed on one side of the reactor 1.

[0033] Furthermore, a groove 17 is provided on one side of the mounting plate 7, and a slider 18 connected to the movable plate 15 is slidably connected inside the groove 17. This is to facilitate the movement of the movable plate 15, which is threaded on the surface of the screw 14, through the slider 18 and the groove 17 when the screw 14 is rotating.

[0034] Furthermore, the positioning holes on the surfaces of the two fixing blocks 13 are not on the same straight line, in order to prevent the positioning rods 16 from being on the same straight line, which would cause the mounting plate 7 to drive the controller 8 to rotate through the positioning rods 16.

[0035] Furthermore, the threads on both sides of the screw 14 are arranged in opposite directions, which is to facilitate the simultaneous movement of the moving plates 15 on both sides of the screw 14 towards each other or away from each other when the screw 14 rotates.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
