Description

Technical Field

[0001] This invention relates to the technical field of a multi-stage circulating demister for sodium sarcosinate production, specifically a multi-stage circulating demister for sodium sarcosinate production. Background Technology

[0002] A demister is used during evaporation when secondary steam carries a large amount of liquid. Although this liquid is separated in the separation chamber, it is still necessary to reduce the amount of entrained liquid droplets to prevent loss of useful products or contamination of the condensate. Therefore, a demister is installed near the steam outlet. There are many types of demisters; the most common type is installed directly on top of the evaporator, while a less common type is installed externally.

[0003] In the prior art, there is a multi-stage circulating demister for sodium sarcosinate production:

[0004] To address this issue, Chinese patent CN216498028U proposes a multi-stage rapid demister based on a water absorption tower. This multi-stage rapid demister utilizes rotating airflow along the inner cavities of staggered first, second, and third teardrop holes on the first, second, and third mesh blocks. Under centrifugal force, liquid substances entrained in the airflow form droplets that are thrown to the sidewalls of the first, second, and third teardrop holes, forming a liquid film. As the liquid film thickens, it flows to the bottom under its own gravity, effectively increasing the airflow path. This results in a longer airflow path, fewer droplets entrained in the discharged gas, higher separation efficiency, and reduced secondary steam pollution. However, in the aforementioned patent, the demister frame cannot be easily adjusted in angle during demistering, making it difficult for the multi-stage circulating demister to filter gases and foam of different flow rates, thus reducing its ease of use.

[0005] Therefore, we propose a multi-stage circulating demister for sodium sarcosinate production to solve the problems mentioned above. Summary of the Invention

A fixed frame is fixedly mounted on one side of the demister, and a first motor is fixedly mounted at one end of the fixed frame. The output end of the first motor is fixedly connected to one side of one of the positioning gears.

[0013] Preferably, the auxiliary defoaming mechanism includes an auxiliary frame, a positioning shaft rotatably disposed at the middle position of the positioning frame, a stirring shaft fixedly disposed at the bottom end of the positioning shaft, a first helical gear fixedly disposed at the top end of the positioning shaft, a fixed seat fixedly disposed at one end of the top of the positioning frame, a fixed shaft rotatably disposed on the inner wall of the fixed seat, a second helical gear fixedly disposed at one end of the fixed shaft, the tooth surface of the first helical gear meshing with the tooth surface of the second helical gear, and an auxiliary mounting frame fixedly disposed on the inner wall of the auxiliary frame.

Through the meshing of the two positioning gears, the tooth surfaces of the two positioning gears mesh with the tooth surfaces of the two positioning tooth rings respectively. The two positioning tooth rings drive the two first telescopic frames to rotate through the rotating frame fixed at one end.

[0018] The output of the second motor, fixed at one end of the demister frame, drives the fixed shaft to rotate. The fixed shaft, positioned by the fixed seat, drives the second helical gear to rotate. The second helical gear meshes with the first helical gear, causing the first helical gear to drive the positioning shaft to rotate along the middle position of the positioning frame. This causes the positioning shaft to drive the stirring shaft fixed at the bottom to rotate and stir, thereby improving and controlling the upward path of the airflow and foam, and increasing the demisting efficiency of the multi-stage circulating demister.

A fixed frame 18 is fixedly mounted on one side of the demister frame 1, and a first motor 19 is fixedly mounted on one end of the fixed frame 18. The output end of the first motor 19 is fixedly connected to one side of one of the positioning gears 17. One side of each of the two third demister pads 12 contacts both sides of the inner wall of the demister frame 1.

[0031] The positioning mechanism includes a limiting frame 5, an electric telescopic rod 20 fixedly mounted on one side of the limiting frame 5, a movable frame 21 fixedly mounted on the telescopic end of the electric telescopic rod 20, a positioning slot 22 fixedly mounted on one end of the movable frame 21, and two second positioning rods 23 fixedly mounted on both ends of one side of the movable frame 21. A second spring 24 is inserted through one end of the outer wall of each of the two second positioning rods 23, and the other ends of the outer walls of the two second positioning rods 23 are respectively inserted and connected to the two ends of one side of the limiting frame 5.

[0033] The auxiliary defoaming mechanism includes an auxiliary frame 2, a positioning shaft 26 rotatably mounted in the middle of a positioning frame 3, a stirring shaft 27 fixedly mounted at the bottom end of the positioning shaft 26, a first helical gear 29 fixedly mounted at the top end of the positioning shaft 26, a fixed seat 31 fixedly mounted at one end of the top of the positioning frame 3, a fixed shaft 32 rotatably mounted on the inner wall of the fixed seat 31, a second helical gear 30 fixedly mounted at one end of the fixed shaft 32, the tooth surface of the first helical gear 29 meshing with the tooth surface of the second helical gear 30, and an auxiliary mounting frame 28 fixedly mounted on the inner wall of the auxiliary frame 2.

[0034] A second motor 6 is fixedly installed at one end of the demister frame 1, and one end of the fixed shaft 32 passes through one side of the demister frame 1 and is fixedly connected to the output end of the second motor 6;

[0035] A switch panel is fixedly provided on one side of the defoaming frame 1. A first motor switch, a second motor switch, and an electric telescopic rod switch are fixedly provided on the surface of the switch panel. The first motor 19, the second motor 6, and the electric telescopic rod 20 are electrically connected to an external power source through the first motor switch, the second motor switch, and the electric telescopic rod switch, respectively.

[0036] The working principle of this embodiment: When a multi-stage circulating demister for sodium sarcosinate production is required, such as... Figures 1-5As shown, the operator turns on the first motor switch, causing the output end of the first motor 19 fixed to one side of the fixed frame 18 to drive one of the positioning gears 17 to rotate. Through the meshing of the two positioning gears 17, the tooth surfaces of the two positioning gears 17 respectively mesh with the tooth surfaces of the two positioning gear rings 16. The two positioning gear rings 16 drive the two first telescopic frames 8 to rotate through the rotating frame 4 fixed at one end. The two first telescopic frames 8 respectively drive the two second telescopic frames 9 to rotate. The positioning of the positioning seat 13 allows one end of the second telescopic frame 9 to be inserted and connected to the first positioning rod 14 fixed on the inner wall of the positioning seat 13. Through the elastic deformation of the first spring 15 inserted on the outer wall of the first positioning rod 14, when the first telescopic frame 8 rotates, the second telescopic frame 9 drives the third demisting pad 12 fixed on the outer wall to tightly contact the inner wall of the demisting frame 1, so that both airflow and foam are filtered and controlled, and the multi-stage circulating demisting device can be conveniently adjusted in angle, increasing the ease of use of the multi-stage circulating demisting device and improving the efficiency of the multi-stage circulating demisting device.

[0037] like Figure 6 As shown, when the electric telescopic rod switch is turned on, the telescopic end of the electric telescopic rod 20 fixed at one end of the limit frame 5 drives the moving frame 21 to move. This causes the moving frame 21 to engage with the positioning slot 22 fixed at one end and the tooth surface of one of the positioning tooth rings 16, thus positioning both positioning tooth rings 16, positioning gear 17, and the first telescopic frame 8, increasing the stability of the multi-stage circulating demister. The second positioning rod 23 fixed at both ends of one side of the moving frame 21 is inserted and connected to both ends of the limit frame 5. Through the elastic deformation of the second spring 24 inserted into the outer wall of the second positioning rod 23 and the positioning of the limit block 25, the auxiliary positioning slot 22 is positioned in normal conditions, so that the multi-stage circulating demister is stably positioned.

[0038] like Figure 2 and Figure 7 As shown, turning on the second motor switch causes the output end of the second motor 6, which is fixed at one end of the demister frame 1, to drive the fixed shaft 32 to rotate. The fixed shaft 32, through the positioning of the fixed seat 31, drives the second helical gear 30 to rotate. The second helical gear 30 meshes with the first helical gear 29, causing the first helical gear 29 to drive the positioning shaft 26 to rotate and connect along the middle position of the positioning frame 3. The positioning shaft 26 then drives the stirring shaft 27, which is fixed at the bottom, to rotate and stir. This improves and controls the upward path of the airflow and foam, thereby increasing the demisting efficiency of the multi-stage circulating demister.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
