The material is thrown into the feed port, causing the motor output end, the stirring shaft and the stirrer to start rotating, and then water is poured into the water inlet. The outer wall of the reactor body is fixedly connected to the aluminum block and the glass insulation inner liner. The aluminum block base has good thermal conductivity, and the glass insulation inner liner has good thermal insulation. The high heat generated by the coupled reactor for the production of ultraviolet absorbers during operation is well recovered. The stirring shaft rotates, causing the threaded ring to rotate, so that the nut moves up and down on the outer wall of the threaded ring, and the cleaning brush rotates up and down on the inner wall of the reactor body to complete the cleaning.

[0004] Regarding the above-mentioned related technologies, the inventor believes that there are the following technical defects that need to be improved:

If the addition rate is too fast, the concentration of the reactants may be too high locally, triggering violent chemical reactions such as sudden temperature and pressure increases. This may not only damage the equipment but also cause safety accidents and increase safety risks. Utility Model Content

[0036] The present application discloses a UV absorber coupling reaction kettle.

[0037] The reactor body 1 is used to store the absorbent and to fully stir the absorbent, the feed hopper 2 is used to quantitatively introduce the absorbent, the inverted V-shaped diverter box 3 is used to separate the absorbent and allow the absorbent to flow into the feed pipe 4 in both directions, the feed pipe 4 is used to introduce the absorbent and allow the absorbent to flow into the reactor body 1 under the action of gravity, the water outlet elbow 5 is used to increase the pipeline resistance and to reduce the fluid flow rate, and the water outlet elbow 5 is attached to the inner wall of the reactor body 1 and the absorbent is poured on the inner wall surface of the reactor body 1, and cooperates with the slow flow component 6 to reduce the impact of the fluid on the reactor body 1.

[0038] The slow-flow assembly 6 includes a sealing gasket 61, a baffle 62 and a foam plastic layer 63. The foam plastic layer 63 is adhesively connected to the inside of the feed pipe 4. The sealing gasket 61 is clamped inside the feed pipe 4. The baffle 62 is installed on the inner side of the sealing gasket 61 at an angle of 45° along the center line direction of the sealing gasket 61.

[0039] Several groups of slow flow components 6 are provided, and the groups of slow flow components 6 are arranged at equal intervals inside the inclined tube of the feed pipe 4 .

[0040] The lower end of the feed hopper 2 is also provided with a support frame 7, a weighing sensor 8, a support block 9 and a straight-connecting pipe 10. The bottom of the straight-connecting pipe 10 passes through the middle of the top of the inverted V-shaped diverter box 3 and fits tightly with the inner wall surface of the inverted V-shaped diverter box 3. The support frame 7 is fixedly connected to the outside of the straight-connecting pipe 10, the weighing sensor 8 is installed on both sides of the top of the support frame 7, and the support block 9 is installed on the upper end of the induction probe of the weighing sensor 8 and is used to contact the feed hopper 2.

[0041] A flow control plate 11 is further installed inside the inverted V-shaped diverter box 3. The flow control plates 11 are symmetrically distributed on both sides of the inner convex surface of the inverted V-shaped diverter box 3 and are used for bidirectional separation of the absorbent.

[0042] An electromagnetic discharge valve 12 is also installed on the outside of the feed pipe 4.

[0043] The bottom discharge end of the inverted V-shaped diverter box 3 is also provided with a liquid outlet 13 having the same diameter as the top pipe opening of the feed pipe 4 .

[0044] A power motor 14, a drive shaft 15 and a stirring rod 16 are also provided in the middle of the reactor body 1. The motor shaft of the power motor 14 is fixedly connected to the top of the drive shaft 15 through a coupling, and the outer wall surface of the drive shaft 15 is fixedly connected to one side of the stirring rod 16. The stirring rod 16 is used for rapid stirring of the absorbent inside the reactor body 1.

[0045] The use process of the ultraviolet absorber coupling reactor in the embodiment of the present application is roughly as follows:

[0046] The material is poured into the feed hopper 2 from the upper end of the hopper, and the support block 9 cooperates with the weighing sensors 8 on both sides to support the feed hopper 2 and weigh the mass of the material in the feed hopper 2 in real time. As the mass of the material increases until the specified addition amount is reached, the discharge valve is opened, and the absorbent enters the interior of the inverted V-shaped diverter box 3 along the straight-connected pipe 10. During this process, the absorbent falls on the tip surface of the middle part of the inverted V-shaped diverter box 3 and spreads along both sides. Then the absorbent flows through the slow flow plate 11 into the feed pipe 4 on one side, realizing the initial deceleration and diversion of the absorbent. After that, the absorbent is divided equally and flows into the feed pipes 4 on both sides. Since the baffle 62 is installed on the inner side of the sealing gasket 61 at an angle of 45 degrees along the center line direction of the sealing gasket 61, the material will first hit the top surface of the baffle 62, slide down to the gathering port under the action of inertia, and then pass through the sealing gasket 61, so that the absorbent can complete the buffering under the joint action of multiple groups of baffles 62. Finally, the material flows along the inner surface of the reactor body 1 through the water outlet elbow 5 and is deposited on the bottom of the reactor, reducing the direct contact between the material and the bottom of the reactor body 1. Finally, the power motor 14 is started to drive the stirring rod 16 to rotate to ensure the efficient progress of the coupling reaction.

[0047] The beneficial technical effects of the ultraviolet absorber coupling reactor of the embodiment of the present application are roughly as follows:

[0048] This product adds an inverted V-shaped diverter box 3 to divert the quantitatively weighed absorbent in conjunction with the slow flow plate 11, so that absorbents of different flow rates can flow into the interior of the feed pipe 4 in both directions, thereby preventing the absorbent from flowing too much on one side and impacting the reactor body 1, thereby improving safety; and this product has multiple sets of sealing gaskets 61 and baffles 62 located inside the feed pipe 4, which cooperate with the water outlet elbow 5 of the discharge port to fully slow down the absorbent and flow it to the inner wall of the reactor body 1, preventing direct impact and increasing damage to the reactor body 1.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
