It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0016] In the following description, many specific details are set forth to fully understand the utility model. However, the utility model can also be implemented in other ways different from those described herein. Therefore, the utility model is not limited by the specific embodiments disclosed in the following specification.
[0017] The utility model provides as Figure 1A continuous finished product mixed powder adding system shown in the figure includes: a feeding station 2, a reaction kettle 11, and a Venturi injector 3. The right side of the Venturi injector 3 is connected to a valve array mixing pipeline 4. An inlet pipeline 6 is connected to the valve array mixing pipeline 4. A flowmeter a 7 is installed on the inlet pipeline 6, and a valve array 5 is installed between the flowmeter a 7 and the valve array mixing pipeline 4. The upper part of the Venturi injector 3 is connected to the bottom of a conical container, and the conical container is arranged on the feeding station 2. The left side of the Venturi injector 3 is connected to the reaction kettle 11 through a reaction kettle feed main pipeline 9. A valve is installed at the upper inlet of the reaction kettle 11, and a flowmeter b 8 is installed on the reaction kettle feed main pipeline 9. The bottom of the reaction kettle 11 is equipped with a discharge pipe, and the other end of the discharge pipe is equipped with a discharge / circulation centrifugal pump 12. The upper part of the discharge / circulation centrifugal pump 12 is connected to a semi-finished product circulation pipeline 13 through a pipeline. A finished product discharge pipeline 14 is installed on one side of the pipeline, and valves are installed on both the finished product discharge pipeline 14 and the semi-finished product circulation pipeline 13.
[0018] Specifically, the number of the inlet pipelines 6 can be increased or decreased according to the process, and a flowmeter and a valve are installed on each inlet pipeline.
[0019] Specifically, there are 3 reaction kettles 11, and they are all fixed on a reaction kettle platform 10, forming a structure of one in use, one in standby and one in temporary storage, so as to realize continuous production. Each reaction kettle is connected to the feed main pipeline 9, and valves are installed at both the inlet and the bottom outlet.
[0020] Specifically, it further includes a vacuum suction feeder 1, and the vacuum suction feeder 1 places the bagged materials on the platform of the feeding station 2.
[0021] Specifically, the semi-finished product circulation pipeline 13 is connected to the valve array mixing pipeline 4, and a check valve is installed near the valve array 5.
[0022] Working principle:
[0023] During operation, an operator uses a vacuum feeder 1 to place bagged materials on the platform of the feeding station 2 and manually opens the bags and pours the materials into the container of the feeding station 2; liquid materials pass through the feed pipe 6, are metered by the flow meter a 7 according to the required proportion, enter the valve matrix 5, where different valves are switched to converge into the valve matrix mixing pipe 4, and then pass through the Venturi injector 3. Using the Venturi principle, the powder from the feeding station is carried into the reaction kettle feed pipe 9. The capacity required for each reaction kettle 11 is metered by the flow meter b 8, and then different valves are switched to enter different reaction kettles 11. The stirring motor of the reaction kettle 11 stirs the materials. There are a total of 3 reaction kettles, with one in use, one in standby, and one in temporary storage, thus realizing continuous production. After stirring is completed, the finished product materials are discharged through the discharge port below the reaction kettle 11, and the discharge / circulation centrifugal pump 12 transports the finished product materials through the finished product discharge pipe 14 to the next process.
[0024] If there is a large amount of powder materials required by the process and a single injection of liquid cannot completely carry the powder materials into the reaction kettle 11 through the Venturi injector 3, at this time, the semi-finished products in the reaction kettle can be pumped out by the discharge / circulation centrifugal pump 12, re-entered into the valve matrix mixing pipe 4 through the semi-finished product circulation pipe 13, then enter the Venturi injector 3, and the powder materials are carried into the reaction kettle 11 through the Venturi injector 3. After all the powder materials are carried into the reaction kettle 11, after stirring is completed, the finished product materials are discharged through the discharge port below the reaction kettle 11, and the discharge / circulation centrifugal pump 12 transports the finished product materials through the finished product discharge pipe 14 to the next process, and then the process is repeated to mix the finished product materials of the next kettle.
