The high-voltage electrostatic generator 106 is used for generating a high-voltage electrostatic field, the injection pump 105 converts liquid in the needle tube into micro liquid drops, and the micro liquid drops are solidified and molded through the condenser tube 104 to obtain electrostatic microspheres;
the condensation pipe 104 constitutes a reaction channel, and fine droplets, which are present in the reaction channel at intervals and continuously fall without collision, fall from above the reaction channel to the glass beaker 103.
Among them, the peristaltic pump is like squeezing a hose filled with fluid with fingers, and moves forward as the fingers slide forward the fluid in the hose. Peristaltic pumps also use the principle of a roller instead of a finger. The fluid is pumped by alternately squeezing and releasing the elastic delivery hose of the pump. Just like squeezing the hose with two fingers, as the fingers move, negative pressure is formed in the hose, and the liquid flows along with the negative pressure. A peristaltic pump is a section of pump tubing between two rotating rollers that forms a "pillow" shaped fluid. The volume of the "pillow" depends on the inner diameter of the pump tube and the geometry of the rotor. The flow rate depends on the product of the rotation speed of the pump head and the three parameters of the size of the pillow and the number of pillows generated by each rotation of the rotor. The size of the "pillow" is generally constant. Pumps with rotors of the same diameter produce pumps with a larger "pillow" volume, with a larger volume of fluid delivered per revolution of the rotor, but with a larger degree of pulsation. This is similar to the case of membrane valves. The pump with smaller pillow volume is generated, and the volume of the fluid conveyed by the rotor of the pump per rotation is smaller; moreover, the small "pillows" formed quickly and continuously allow for a smoother flow of fluid. Thus, the use of peristaltic pumps in this application has greater cycling advantages.
The magnetic stirrer is used for liquid mixing, stirring or heating and stirring low-viscosity liquid or solid-liquid mixture. The basic principle is that magnetic stirrer inside container is driven by magnetic field to rotate circularly to stir liquid. The cooperation heating temperature control system can heat and control the sample temperature according to specific experimental requirement, maintains the required temperature condition of experimental condition, guarantees that liquid mixes and reaches the experiment demand. In the present application, precise control of the reaction can be achieved.
In one embodiment, the combining frame 101 is detachable, and the condensation pipe 104 is fixed on the combining frame 101, so that the assembly and disassembly before and after the installation test are convenient.
In one embodiment, the inner diameter of the condenser tube 104 is 9-11mm, preferably 10 mm. The diameter of the reaction pipeline cannot be too small, and when the gel balls injected from the injection pump 105 fall to the lower part of the oil column and are easily gathered together, the pipeline is easily blocked if the diameter is too small.
In one embodiment, the liquid flow direction of the water circulation pipeline a is from bottom to top, the magnetic stirrer 108 is disposed on the liftable platform 102, and the glass beaker 103 is disposed on the magnetic stirrer 108. Therefore, in the embodiment, the material taking mode adopts the mode of adjusting the height of the lifting platform 102 and then taking the glass beaker, so that the cleaning is convenient.

Thereby satisfying: the liquid drops in the form of liquid drops, and the liquid drops at the upper end of the oil column can not collide, so that the flow rate of the injection pump can be regulated within a certain range.
In one embodiment, peristaltic pump 107 controls the flow of liquid through the tubing by rotating in a forward direction and a reverse direction. The reaction oil is stored in the equipment, recycled, automatically supplied and recovered, and controlled by positive and negative rotation of a peristaltic pump (the lower part of the condensation pipe 104 enters and exits).
In one embodiment, the oil circulation line B is provided with a piston 1048 located in the upper glass tee 1043.
