Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a novel solid-liquid mixing system. Background Art

[0002] In the past, the mixing of solids and liquids was often done manually, which resulted in extremely low mixing effect and efficiency, high quality risk, and high labor intensity. Currently, there are only liquid mixing and solid mixing devices on the market, but no mixing device that can combine mixing effect and efficiency with a high degree of automation.

[0003] In the development in recent years, although some semi-automatic devices have emerged to achieve solid-liquid mixing, their usage scenarios and conditions are relatively high, which magnifies its limitations. Under some conditions, uniform mixing cannot be achieved, such as highly volatile liquids or flammable liquids. Especially for applications with highly volatile liquids, such as ammonia water, concentrated hydrochloric acid, concentrated nitric acid, etc., these substances should be stored in a sealed state and away from heat sources to prevent accelerated volatilization due to heat; for example, when the amount of liquid and solid differs by thousands or even tens of thousands of times, how to mix the liquid and solid efficiently and evenly, at this time, the handling during the mixing process is particularly important.

[0046] In a specific embodiment, see Figure 1 The liquid feeding mechanism 2 includes a pressurized pipe 21, a liquid storage tank 22, a liquid feed pipe 23, and an atomizing nozzle 24 connected in sequence. The pressure from the pressurized pipe 21 causes the liquid in the liquid storage tank 22 to be transported to the atomizing nozzle 24 through the liquid feed pipe 23, and sprayed on the surface of the solid material in the mixing device 3 in an atomized form; the pressurized pipe 21 conveys compressed air, and a pressure valve 5 and a pressure instrument are provided on the pressurized pipe 21. The pressure valve 5 is used to adjust the pressure entering the liquid storage tank 22 and control the feeding speed, and the compressed air machine that conveys compressed air to the pressurized pipe 21 is connected to the central control system 4, and the pressure and opening and closing are controlled by the central control system 4; in order to reduce the impurities in the liquid entering the mixing device and facilitate atomization, a filter bag is provided in the liquid storage tank 22, and the liquid in the liquid storage tank 22 is filtered by the filter bag under the pressure conveyed by the pressurized pipe 21 and then conveyed to the mixing device 3.

At this time, the vibration hammer 32 can still be turned on, so that the material on the inner wall of the mixing tank body 31 falls into the material collector 6 to avoid the mixed material from hanging on the wall.

[0050] In a further implementation process, a pressure regulating valve 7 is provided on the top cover of the mixing tank 31 to balance the tank pressure and prevent the loss of atomized materials. An encoder 8 electrically connected to the central control system 4 is provided on the driving mechanism 33 to control the rotation angle and process time of the mixing tank 31.
