Description

Technical Field

[0001] The utility model relates to the technical field of ceramic ink production, in particular to an ink pilot production matching device. Background Art

[0002] Pilot production of ceramic ink refers to a medium-scale production test conducted after the ink formula is successfully developed on a small scale in the laboratory to verify and optimize the feasibility, stability and consistency of the formula under larger-scale production conditions. Pilot production is an important transition step from small-scale laboratory research and development to large-scale industrial production.

[0003] In the existing equipment, the ball mill, dryer and reactor are fixedly connected, which results in the need to completely stop production for each pilot test. This is time-consuming and seriously affects the production schedule. Moreover, if different ball mills are used for pilot grinding, the accuracy of the data will be affected. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide an ink pilot production matching device. Through the coordinated use of a pilot kettle and a reciprocating frequency conversion pump, the liquid phase reaction liquid is mixed in advance in the pilot kettle. During the normal production interval, the liquid phase material in the pilot kettle and the powder in the ball mill are added to the reactor for premixing. After that, they are pumped back into the pilot kettle by a reciprocating frequency conversion pump, and the spray plate is turned on. While replenishing the pilot reaction with liquid, the inner wall of the reactor and the stirring paddle of the reactor are also flushed, thereby realizing the pilot reaction while minimizing the impact on normal production.

[0005] The utility model is realized by adopting the following technical solutions:

[0008] The reactor is provided with a reactor stirring paddle inside, a spray plate is provided above the reactor stirring paddle, and a liquid replenishing pipeline is connected to the spray plate. The spray plate is used to replenish the liquid phase and wash the inner wall of the reactor and the reactor stirring paddle.

[0009] The pilot kettle outlet pipeline is provided with a pilot kettle outlet pipeline valve, the connection between the return pilot kettle pipeline and the pilot kettle outlet pipeline is located between the reciprocating frequency conversion pump and the pilot kettle outlet pipeline valve, and the return pilot kettle pipeline is provided with a return pilot kettle pipeline valve.

[0010] A pipeline out of the reactor is arranged between the reciprocating variable frequency pump and the reactor, and a pipeline valve out of the reactor is arranged on the pipeline out of the reactor.

[0011] The reactor outlet pipeline is connected with a reactor inlet pipeline, and a reactor inlet pipeline valve is arranged on the reactor inlet pipeline.

[0012] The connection point between the inlet pipeline of the reactor and the outlet pipeline of the reactor is located between the reciprocating variable frequency pump and the valve of the outlet pipeline of the reactor.

Among them, the spray plate is used to add liquid phase and rinse the inner wall of the reactor and the reactor stirring paddle.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] By adopting the ink pilot production matching device of the utility model, the liquid phase reaction liquid is mixed in advance in the pilot kettle through the coordinated use of the pilot kettle and the reciprocating frequency conversion pump. The liquid phase material in the pilot kettle and the powder material in the ball mill are added to the reactor for premixing during the normal production interval. After that, they are pumped back into the pilot kettle by the reciprocating frequency conversion pump.
