Due to the high process requirements of acidification reactions, the ratio of catalyst to reactants needs to be strictly controlled. Currently available acidification reactors have certain shortcomings in the catalyst introduction process, mainly manifested in inaccurate feed rates. Existing devices typically use the start and stop of pumps to control catalyst delivery; however, because a certain amount of catalyst remains in the pipeline, even when the pump stops, material continues to flow into the reactor, causing the catalyst dosage to exceed the preset range, thus affecting the accuracy of the reaction ratio. Therefore, an acidification reactor with metering capabilities is needed to solve the above-mentioned technical defects. Utility Model Content

Through differential stirring, a better acidification reaction is achieved. Attached Figure Description

The lower part of the pump 5 is equipped with... A metering sensor 6 is installed. A baffle plate 7 is fixedly connected to the movable end of the cylinder 2. A first drive motor 9 is installed at one bottom end of the baffle plate 7. A feeding wheel 8 is fixedly connected to the output shaft of the first drive motor 9. The feeding wheel 8 is located at the bottom of the baffle plate 7. The baffle plate 7 is set inside the feeding tank 4. A configuration port 10 is set at the lower left of the feeding tank 4. The bottom of the feeding tank 4 is inclined towards the kettle body 23. The width of the feeding wheel 8 is flush with the baffle plate 7. A reserved groove for the baffle plate 7 to move up and down is opened on the top of the feeding tank 4.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, pump 5 extracts particulate catalyst from storage tank 1 to distribution tank 4. The metering sensor 6 monitors the metering amount in real time and compares it with the preset flow rate. Based on the output signal of the controller, when the amount of material extracted approaches the preset amount, the pumping speed of pump 5 is adjusted in real time to adjust the catalyst feed amount so that it approaches and is maintained within the set feed flow rate range. At the same time, the rotation speed of the feeding wheel 8 changes from fast to slow, and the cylinder 2 drives the baffle plate 7 to gradually descend until the feed amount is reached. Then the feeding wheel 8 abuts against the bottom of distribution tank 4 and stops rotating, preventing the input of excess particles.

[0024] Four sets of support legs 11 are fixedly connected to the bottom of the vessel body 23. The vessel body 23 is supported on the ground by the support legs 11. A discharge port 13 is opened at the bottom of the vessel body 23. A discharge pipe 12 is installed at the bottom of the discharge port 13 and is connected to the material container.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, automatic metering eliminates the need for manual intervention, reducing the workload of manual proportioning, enabling continuous production, reducing fatigue from manual monitoring and operation, and thus lowering labor costs.

[0026] A third drive motor 20 is fixedly connected to the top of the vessel body 23. The output shaft of the third drive motor 20 is fixedly connected to a stirring shaft 21. The stirring shaft 21 extends into the interior of the vessel body 23 and has multiple sets of parallel stirring rods 14 distributed on its outer wall. A bushing 17 is movably sleeved on the outside of the stirring shaft 21. The bushing 17 is movably assembled at the top of the vessel body 23. A large gear 22 is fixedly sleeved on the outer wall of the bushing 17. A second drive motor 19 is fixedly connected to the right side of the top of the vessel body 23. A small gear 18 is fixedly connected to the output shaft of the second drive motor 19. The large gear 22 and the small gear 18 are meshed. Two sets of stirring plates 15 are fixedly connected to the outer wall of the bushing 17. The stirring plates 15 are symmetrically distributed about the axis of the bushing 17.

The stirring shaft 21 and the bushing 17 are coaxial. When the third drive motor 20 drives the stirring shaft 21 to rotate, the stirring rod 14 rotates at high speed. When the second drive motor 19 drives the pinion 18 to rotate, the pinion 18 drives the large gear 22 to mesh and rotate, thereby driving the stirring plate 15 to stir through the bushing 17.

[0028] Working principle: Material is fed into the device through inlet 16. The device is equipped with two sets of stirring components. During the acidification reaction, one set consists of stirring rod 14 and the other set consists of stirring plate 15. The stirring shaft 21 and the bushing 17 are coaxial. When the third drive motor 20 drives the stirring shaft 21 to rotate, the stirring rod 14 rotates at high speed. When the second drive motor 19 drives the pinion 18 to rotate, the pinion 18 drives the large gear 22 to mesh and rotate, thereby driving the stirring plate 15 to stir through the bushing 17. The pump 5 extracts the particulate catalyst from the storage tank 1 to the distribution tank. Tank 4 monitors the metering amount in real time through metering sensor 6 and compares it with the preset flow rate. Based on the output signal of the controller, when the amount of material being pumped approaches the preset amount, the pumping speed of pump 5 is adjusted in real time to adjust the amount of catalyst being fed, so that it approaches and is maintained within the set feed flow rate range. At the same time, the rotation speed of the feeding wheel 8 changes from fast to slow, and the baffle plate 7 is driven by cylinder 2 to gradually descend until the feed amount is reached. Then the feeding wheel 8 stops at the bottom of the feeding tank 4 to prevent the input of excess particles.
