DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. The embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] Reference Figs. 1-3A reactor with a defoaming structure includes a reactor body 1 and multiple heating wires 4. The top inner wall of the reactor body 1 is rotatably connected to a connecting shaft 5. The top outer wall of the reactor body 1 is fixed with a motor by bolts. One end of the motor output shaft is fixed to the connecting shaft 5. The outer side of the connecting shaft 5 is slidably connected to a slip ring 9. The circumferential outer wall of the slip ring 9 is fixed with a fixing block 12 by bolts. One side of the fixing block 12 is rotatably connected to a connecting rod 13. A floating ball 15 is installed at one end of the connecting rod 13. A plurality of defoaming needles 14 are provided on the outer side of the connecting rod 13. The rotation of the connecting shaft 5 causes the slip ring 9 to drive the connecting rod 13 to rotate. Under the action of centrifugal force, The middle position of the raw material liquid level is low and the two sides are high. At this time, the connecting rod 13 rotates and tilts, and the outer end of the connecting rod 13 is upward through the float 15, so that the defoaming needle 14 is in contact with the liquid surface, and then the defoaming needle 14 defoams the raw material more fully and evenly. The bottom of the slip ring 9 is bonded with a float ring 16. The raw material solution is added to the kettle body 1. At this time, the slip ring 9 moves along the connecting shaft 5 and floats on the liquid surface of the raw material through the float 15 and the float ring 16. The bottom end of the connecting shaft 5 is fixed with a stirring frame 6 by bolts. The rotation of the motor causes the connecting shaft 5 to drive the stirring frame 6 to rotate, so that the raw materials in the kettle body 1 are stirred.

[0023] The stirring rack 6 is fixed to the rotating ring 7, and the stirring rack 6 is fixed to the rotating ring 7. The stirring rack 6 rotates to rotate the rotating ring 7, and the rotating ring 7 can guide the stirring rack 6 so that it can rotate stably. The bottom of the stirring rack 6 is fixed with a scraper 10 by bolts, and the scraper 10 contacts the bottom inner wall of the kettle body 1. The stirring rack 6 rotates to rotate the scraper 10, so that the scraper 10 scrapes the raw materials at the bottom of the kettle body 1 to prevent the raw materials from being deposited at the bottom of the kettle body 1. The bottom of the kettle body 1 is connected and fixed with a discharge pipe 8, and the side of the kettle body 1 is connected with a liquid level gauge 2. The liquid level gauge 2 facilitates the staff to directly observe and understand the amount of raw materials in the kettle body 1. The top of the kettle body 1 is connected and fixed with a feed pipe 3.

[0024] Working principle: When defoaming is required, the raw material solution is first introduced into the kettle body 1 through the feed pipe 3, the slip ring 9 moves along the connecting shaft 5, and floats on the liquid surface of the raw material through the float 15 and the float ring 16. The motor is started, and the motor rotates to make the connecting shaft 5 drive the stirring frame 6 to rotate, so that the raw materials in the kettle body 1 are stirred. At the same time, the connecting shaft 5 rotates to make the slip ring 9 drive the connecting rod 13 to rotate. Under the action of centrifugal force, the middle position of the raw material liquid level is low and the two sides are high. At this time, the connecting rod 13 rotates upward and tilts, and the outer end of the connecting rod 13 is upward through the float 15, so that the defoaming needle 14 is in contact with the liquid surface, thereby making the raw material more fully and evenly defoamed.

[0025] Finally, it should be noted that those skilled in the art may modify the technical solutions described in the aforementioned embodiments or replace some of the technical features with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of this utility model shall be included within the scope of protection of this utility model.
