Description

Technical Field

[0001] This utility model relates to the field of raw material mixing technology, specifically to a raw material mixing device for a conductive polymer dispersion. Background Technology

[0002] The raw materials for conductive polymer dispersions mainly include conductive polymer particles and conductive fillers. By adding selected polymers and conductive fillers to a solvent and mixing and stirring, the particles are uniformly dispersed in the solution. The raw materials need to be stirred and mixed in the mixing tank. The common mixing method is to pour the material into the tank and stir it through a single stirring shaft. The liquid flow direction in the tank is unidirectional, and the mixing efficiency is low. Therefore, this solution provides a raw material mixing device for conductive polymer dispersions.

The mixing tank is fixedly installed on the support frame, and a vertical fixing frame is installed on the top of the support frame, with the fixing frame located on one side of the mixing tank. The top of the mixing tank is semi-open, and an auxiliary material feed hopper is provided on the top of the tank lid. A first stirring motor is fixed on one side of the auxiliary material feed hopper, and a sleeve is connected to the bottom of the auxiliary material feed hopper. A first stirring rod is connected to the bottom of the first stirring motor, and the first stirring rod is located inside the sleeve. A circular funnel is installed at the bottom of the sleeve, and the stirring blade at the bottom of the first stirring rod is located inside the circular funnel.

[0009] Beneficial effects

[0010] This invention provides a raw material mixing device for conductive polymer dispersions, which has the following advantages:

[0011] In this device, raw materials and auxiliary materials can be fed into the mixing tank from the top opening and the auxiliary material feed hopper, respectively. While the mixing tank is rotating and stirring, the second stirring rod can also move up and down repeatedly under the action of the lead screw.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: a raw material mixing device for conductive polymer dispersion, including a support frame 1, a mixing tank 2, a fixing frame 3 and an auxiliary material feeding hopper 4. The mixing tank 2 is fixedly installed on the support frame 1. A vertical fixing frame 3 is installed on the top of the support frame 1 and is located on one side of the mixing tank 2. The top of the mixing tank 2 is semi-open. An auxiliary material feeding hopper 4 is provided on the top of the tank cover of the mixing tank 2. A first stirring motor 5 is fixed on one side of the auxiliary material feeding hopper 4. A sleeve 6 is connected to the bottom of the auxiliary material feeding hopper 4. A first stirring rod 7 is connected to the bottom of the first stirring motor 5 and is located inside the sleeve 6. A circular funnel 8 is installed at the bottom of the sleeve 6. The stirring blade at the bottom of the first stirring rod 7 is located inside the circular funnel 8. Several inclined holes 9 are opened on the outer wall surface of the circular funnel 8.

[0019] A vertical lead screw 10 is installed on the fixed frame 3. A lead screw drive motor 11 is installed on the top of the lead screw 10. The motor shaft of the lead screw drive motor 11 is fixed to the lead screw 10, driving the lead screw 10 to rotate longitudinally. A lead screw nut slider 12 is slidably installed on the lead screw 10. A crossbeam plate 13 is fixed on the outside of the lead screw nut slider 12. A second stirring motor 14 is installed on the crossbeam plate 13. A second stirring rod 15 is connected to the bottom of the second stirring motor 14, and the second stirring rod 15 is located at the center of the mixing tank 2.

[0020] There is a gap between the sleeve 6 and the first stirring rod 7. The raw material fed from the auxiliary feed hopper 4 falls through the gap and into the circular funnel 8 at the bottom of the sleeve 6.

[0021] The second stirring rod 15 is equipped with a fan-shaped stirring blade, and the bottom of the mixing tank 2 is provided with a piston discharge port 16.

[0022] The lead screw drive motor 11 drives the lead screw 10 to rotate inside the fixed frame 3. The lead screw drive motor 11 is a forward and reverse motor, used to drive the lead screw 10 to rotate from left to right or from right to left along its longitudinal axis. By changing the direction of rotation of the lead screw 10, the lead screw nut slider 12 is driven to move up and down.

[0023] The mixing method for raw materials is as follows:

[0024] In this device structure, when mixing raw materials, the raw materials and various auxiliary materials can be directly fed into the mixing tank 2 from the top opening and into the auxiliary material feed hopper 4 respectively. The material particles fed into the auxiliary material feed hopper 4 need to be smaller than the gap between the sleeve 6 and the first stirring rod 7. Water can also be directly fed into the mixing tank 2 from the top opening.

[0025] During the mixing process, the first stirring motor 5 drives the first stirring rod 7 to rotate inside the sleeve 6. The sleeve 6 is fixedly installed on one side inside the mixing tank 2. A circular funnel 8 is installed at the bottom of the sleeve 6. The auxiliary material falls from the gap between the sleeve 6 and the first stirring rod 7 into the circular funnel 8 and is stirred in the circular funnel 8 by the stirring blades at the bottom of the first stirring rod 7.

[0026] At the same time, the lead screw drive motor 11 drives the lead screw 10 to rotate longitudinally from left to right and from right to left. The lead screw nut slider 12 performs lead screw transmission in the cooperation of the internal circulation channel and the ball bearings, and moves up and down along the lead screw 10. This allows the crossbeam plate 13 and the second stirring motor 14 to be adjusted in height. This allows the second stirring rod 15 at the bottom of the second stirring motor 14 to be adjusted in height in the mixing tank 2, so that the material is mixed more evenly in the mixing tank 2.

[0027] When the lead screw nut slider 12 moves downward to the bottom of the lead screw 10, there is still a height gap between the bottom of the second stirring rod 15 and the ground inside the mixing tank 2; this prevents the second stirring rod 15 from contacting the bottom surface of the mixing tank 2 after moving downward and affecting the rotation.

[0028] When the main material and auxiliary material are mixed, the main material is stirred and mixed with water in the mixing tank 2 by the second stirring rod 15 which is adjusted up and down and moves. The auxiliary material falls from the inside of the sleeve 6 into the circular sieve 8 and is stirred by the first stirring rod 7. Some water and raw materials will enter the circular sieve 8 and mix with the auxiliary material. After being stirred, they will escape from the opening on the top of the circular sieve 8 and from several inclined holes 9 on the outer surface, so that the various materials can be fully stirred and mixed in the mixing tank 2, improving the mixing efficiency. Finally, the piston of the piston outlet 16 is opened to pour out the mixed material.

[0029] 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.
