[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] An apparatus for processing polymer microspheres, comprising:

[0027] A mixing tank 1 is equipped with a first stirring assembly, which includes a first servo motor 9, a first stirring frame 10, and a spiral blade 11. The first servo motor 9 is installed on the mixing tank 1, and the output end of the first servo motor 9 is connected to the extension end of the first stirring frame 10 that passes through the mixing tank 1. The spiral blade 11 is disposed on the first stirring frame 10 and is located inside the discharge pipe 2.

[0028] After the solid and liquid raw materials enter the mixing tank 1, the first servo motor 9 drives the first stirring frame 10 to rotate, and the spiral blades 11 installed on the first stirring frame 10 rotate accordingly to stir and mix the materials in the tank. The spiral blades 11 not only thoroughly stir the materials in the mixing tank 1, but the part extending into the discharge pipe 2 can also further stir the materials during discharge to ensure uniform mixing. After mixing is completed, the control valve 3 on the discharge pipe 2 is opened, and the uniformly mixed materials are discharged through the discharge pipe 2 under the action of gravity and the pushing action of the spiral blades 11, and enter the subsequent processing steps.

[0029] A solid feeding assembly is provided on one side of the upper end of the mixing tank 1. The solid feeding assembly includes a feeding box 12, a feeding pipe 13, a second servo motor 14, a grinding wheel 15, and a screen 16. The feeding pipe 13 is connected between the feeding box 12 and the mixing tank 1. The second servo motor 14 is installed on the feeding box 12, and the output end of the second servo motor 14 is connected to the grinding wheel 15 through a rotating rod that passes through the feeding box 12. A grinding chamber 17 is provided inside the feeding box 12, and the screen 16 is installed at the lower end of the grinding chamber 17. A liquid feeding mechanism is provided on the other side of the mixing tank 1. A discharge pipe 2 is provided at the lower end of the mixing tank 1, and a control valve 3 is installed on the discharge pipe 2.

[0030] Solid raw materials are fed into the grinding chamber 17 from the top of the feed box 12. The second servo motor 14 drives the rotating rod to rotate the grinding wheel 15 at high speed, crushing the raw materials. The crushed raw materials fall onto the screen 16 at the bottom of the grinding chamber 17. Solid particles that meet the particle size requirements pass through the screen 16 and are transported to the mixing tank 1 via the feed pipe 13. Larger particles that do not meet the requirements remain above the screen 16 and continue to be ground until the particle size is qualified.

[0031] The liquid feeding mechanism includes a first feeding tank 4, a second feeding tank 5, a first feeding component, and a second feeding component. A support frame 6 is installed on the mixing tank 1. A weighing sensor 7 is installed between the support frame 6 and the first feeding tank 4. A second stirring component is installed on both the first feeding tank 4 and the second feeding tank 5. The second stirring component includes a third servo motor 23 and a second stirring frame 24. The third servo motor 23 is installed on the first feeding tank 4 and the second feeding tank 5 respectively, and the output end of the third servo motor 23 is connected to the extension end of the second stirring frame 24 that passes through the first feeding tank 4 and the second feeding tank 5. A liquid level sensor 8 is installed on both the first feeding tank 4 and the second feeding tank 5. The second feeding tank 5 is connected to the mixing tank 1 by a support rod.

[0032] Specifically, both the first feeding assembly and the second feeding assembly include a feeding pipe 18, a one-way valve 19, and a Coriolis mass flow meter 20. One end of the feeding pipe 18 is connected to the first feed tank 4 and the second feed tank 5, respectively, and the other end of the feeding pipe 18 is connected to the mixing tank 1. The one-way valve 19 and the Coriolis mass flow meter 20 are both installed on the feeding pipe 18. The first feeding assembly and the second feeding assembly also include a plunger pump 21 and a diaphragm pump 22, respectively, which are installed on the feeding pipe 18.

[0033] The operator sets the amount of liquid raw material to be added to the first feed tank 4 and the second feed tank 5 via the controller 25. The third servo motor 23 inside the first feed tank 4 and the second feed tank 5 drives the second stirring frame 24 to rotate, stirring the liquid raw material in the tank to prevent sedimentation and stratification, and to ensure its uniformity. At the same time, the liquid level sensor 8 monitors the liquid level in the first feed tank 4 or the second feed tank 5 in real time and feeds the data back to the controller 25. When the liquid level sensor 8 detects that the liquid level in the first feed tank 4 or the second feed tank 5 is lower than the set threshold, the controller 25 sends a signal to the plunger pump 21 or the diaphragm pump 22 to stop feeding.

[0034] During addition, either the plunger pump 21 or the diaphragm pump 22 in the first or second feeding assembly is activated, selected based on the viscosity difference of the liquid raw material: the plunger pump 21 is used for conveying high-viscosity liquids, and the diaphragm pump 22 is used for conveying low-viscosity liquids. The liquid raw material flows out through the feeding pipe 18, the check valve 19 prevents backflow, and the Coriolis mass flow meter 20 accurately measures the liquid mass flow rate and transmits the data to the controller 25.

[0035] The weighing sensor 7, installed between the support frame 6 and the first feed tank 4, monitors the weight change of the first feed tank 4 in real time and calibrates with the data from the Coriolis mass flow meter 20 to ensure the accuracy of the liquid addition. When the actual addition amount approaches the set value, the controller 25 automatically adjusts the pump's operating parameters to reduce the flow rate, achieving precise addition and avoiding over-addition.

[0036] Based on the above embodiments, a controller 25 is installed on the mixing tank 1. The controller 25 is electrically connected to the weighing sensor 7, the liquid level sensor 8, the first servo motor 9, the second servo motor 14, the one-way valve 19, the Coriolis mass flow meter 20, the plunger pump 21, the diaphragm pump 22 and the third servo motor 23.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
