DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0021] As shown in Figure 1 and Figure 2 The utility model provides a kind of technical scheme of reaction kettle quantitative feeding device, including reaction kettle body 1, reaction kettle body 1 is equipped with feed inlet 2, reaction kettle body 1 is fixedly installed with first support 3, first support 3 side is fixedly installed with second support 4, first support 3 and second support 4 are installed with feeding mechanism 5, reaction kettle body 1 top is equipped with spraying material mechanism 6, by the cooperation of feeding mechanism 5 and spraying material mechanism 6, quantitative catalyst solution can be evenly sprayed in reaction kettle body 1.
[0022] As shown in Figure 2 and Figure 3As shown, the feeding mechanism 5 includes a piston cylinder 508 fixedly installed on the first support 3, and a servo push rod 506 fixedly installed on the second support 4. The piston cylinder 508 is fixedly installed with shaft sealing sleeves 505 on both sides, and is slidingly installed with a piston plate 504 inside. The piston plate 504 is fixedly installed with a piston column 501, and the upper half of the piston cylinder 508 is connected with a feeding pipe 503. The lower half of the piston cylinder 508 is connected with a discharging pipe 507. The feeding pipe 503 and the discharging pipe 507 are both provided with one-way valves 502 at the connection positions. The piston column 501 extends out of the piston cylinder 508 through the shaft sealing sleeves 505, and the shaft sealing sleeves 505 are provided with sealing rings inside.
[0023] Specifically, when the piston plate 504 moves forward, the catalyst solution at the front end of the piston cylinder 508 is pushed into the discharging pipe 507, while the catalyst solution in the feeding pipe 503 is sucked into the rear end of the piston cylinder 508. Conversely, when the piston plate 504 moves backward, the catalyst solution at the rear end of the piston cylinder 508 is squeezed into the discharging pipe 507, while the catalyst solution in the feeding pipe 503 is sucked into the front end of the piston cylinder 508. Through such reciprocating movement, the piston plate 504 can continuously pump the catalyst solution through the spray head 607 and add it into the reaction kettle body 1. In addition, by accurately controlling the moving stroke of the piston plate 504, a quantitative amount of catalyst solution can be added into the reaction kettle body 1.
[0024] As shown in Figure 2 and Figure 4 , the feeding mechanism 6 includes a mounting base 601 fixedly installed on the top of the reaction kettle body 1. The mounting base 601 is rotatingly installed with a gear 603, and is slidingly installed with a rack 602. The rack 602 is fixedly installed on the other end of the piston column 501 at the end. The gear 603 is fixedly installed with a driving shaft 604, and the driving shaft 604 is fixedly installed with a rotating frame 606 at the lower end. The rotating frame 606 is fixedly installed with a spray head 607 at the bottom. The spray head 607 is connected with branch pipes 605. The discharging pipe 507 is provided with a rotating joint 608 at the end. The mounting base 601 is provided with a sliding groove, and the rack 602 is slidingly installed on the mounting base 601 through the sliding groove.
[0025] Specifically, in the process of the reciprocating motion of the piston column 501, the rack 602 is effectively driven to perform corresponding reciprocating motion. With the reciprocating motion of the rack 602, the gear 603 is further driven to rotate. Once the gear 603 starts to rotate, power is transmitted to the drive shaft 604, so that the drive shaft 604 also starts to rotate. The rotating action of the drive shaft 604 further drives the spray head 607 on the rotating frame 606 to rotate. In the process of rotation, the spray head 607 uniformly sprays the catalyst solution on the inner wall of the reaction kettle body 1, ensuring uniform distribution of the catalyst solution.
[0026] The working principle is that when the piston column 501 is driven to reciprocate forward and backward by the servo push rod 506, the piston column 501 drives the piston plate 504 to reciprocate in the piston cylinder 508. When the piston plate 504 moves forward, the catalyst solution in the front part of the piston cylinder 508 is squeezed into the discharge pipe 507, and the catalyst solution in the feed pipe 503 is sucked into the rear part of the piston cylinder 508. When the piston plate 504 moves backward, the catalyst solution in the rear part of the piston cylinder 508 is squeezed into the discharge pipe 507, and the catalyst solution in the feed pipe 503 is sucked into the front part of the piston cylinder 508. Therefore, when the piston plate 504 reciprocates, the catalyst solution is pumped through the spray head 607 to be continuously discharged and added to the reaction kettle body 1, and a certain amount of catalyst solution can be added to the reaction kettle body 1 by controlling the stroke of the piston plate 504. At the same time, in the process of reciprocating motion of the piston column 501, the rack 602 is driven to reciprocate, the rack 602 drives the gear 603 to rotate, the gear 603 drives the drive shaft 604 to rotate, and the drive shaft 604 drives the spray head 607 on the rotating frame 606 to rotate, so that the catalyst solution is uniformly sprayed in the reaction kettle body 1.

Therefore, the embodiments should be considered in all aspects as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the foregoing description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced in the present application.
