[0028] A lifting assembly, the lifting assembly includes two electric push rods 9 fixedly connected to the top of the mixing bin 2, and the tops of the electric push rods 9 are fixedly connected to a through-groove plate 4. The arrangement of the electric push rods 9 helps the mixing assembly to move up and down while mixing the pulp, further improving the mixing effect of the pulp;

[0029] The defoaming assembly includes a plurality of mesh bodies 14 fixedly connected to a stirring body 15. Because foam will appear when the pulp is stirred, if it is not removed in time, the pulp will be affected in mixing. The mesh bodies 14 are arranged to rotate and move together with the stirring body 15, which helps to improve the defoaming effect.

[0030] Furthermore, the stirring body 15 and the stirring body 2 16 pass through the top of the stirring chamber 2 and are fixedly connected to a relatively arranged bevel gear 1 6.

The pulp enters the mixing bin 2 through the feed pipe 3 and is stirred evenly. At the same time, the operation of the vacuum pump 5 can form a negative pressure in the mixing bin 2 to avoid bubbles during stirring. After stirring evenly, the valve 11 is opened to discharge the pulp.

[0035] Furthermore, a scale groove 10 is provided on the outer wall of the mixing chamber 2. The scale groove 10 is transparent, which is helpful for observing the feeding amount. A certain amount of pulp can be injected into the mixing chamber 2 according to demand.

[0036] The specific working method is: at the beginning, close the valve 11, and the pulp enters the mixing chamber 2 through the feed pipe 3. The amount of pulp entering the mixing chamber 2 can be controlled according to the displayed value of the scale groove 10. The rotating mixing body 15 and the mixing body 2 16 mix the pulp evenly. The arc-shaped rubber scraper 151 can scrape the pulp on the inner wall of the mixing chamber 2. At the same time, the electric push rod 9 is extended and retracted to drive the mixing component to move to improve the pulp mixing effect. The vacuum pump 5 continues to operate to form a negative pressure in the mixing chamber 2. The mesh body 14 rotates with the mixing component to help remove foam and bubbles when the pulp is stirred. After stirring, open the valve 11 to discharge the pulp.
