In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments may be used in combination with each other.

[0025] Embodiment 1: Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a vacuum mixing evaporator, the vacuum mixing evaporator includes: a main tower 3, an air outlet 2 is arranged above the main tower 3, the air outlet 2 is connected to a transition pipe 9, a first flange 15 is arranged at the air outlet 2, a first side plate 10 is arranged on the side of the first flange 15, a column 11 is arranged on the first side plate 10, an abutting frame 13 is arranged inside the transition pipe 9, a blocking ring 12 is connected to the outside of the abutting frame 13, a blocking ring 14 is arranged on the abutting frame 13, a second flange 16 is arranged at one end of the transition pipe 9, a second side plate 17 is arranged on the side of the second flange 16, a bottom block 19 is arranged at the bottom of the second side plate 17, and a guide hole 18 is opened on the surface of the second side plate 17;

[0026] The abutting frame 13 is composed of a central cylindrical block and several support rods. The several support rods are evenly distributed on the central cylindrical block. The several support rods are connected by welding and the blocking ring 12. The blocking ring 12 adopts an annular structure. The blocking ring 12 is arranged on the inner side surface of the transition pipe 9 by welding. The outer surface of the blocking ring 12 is closely attached to the inner surface of the transition pipe 9. The blocking ring 14 is in an annular structure. The blocking ring 14 is fixed on the abutting frame 13 by welding. There are several blocking rings 14. The several blocking rings 14 are evenly offset from the central cylinder towards the blocking ring 12. Both sides of the bottom of the blocking ring 14 are chamfered. The cross-section of the blocking ring 14 is triangular.

[0027] During use, the provided blocking ring 14 is annular, and the several blocking rings 14 are evenly offset from the central cylinder towards the blocking ring 12. A gap is formed between the blocking rings 14 to prevent the suction force in the outer connecting pipe 1 from directly acting on the material itself, thereby blocking the running of the liquid material and avoiding material loss. The outer side of the abutting frame 13 is provided with a blocking ring 12. The blocking ring 12 is tightly attached to and welded to the inner surface of the transition pipe 9, improving the sealing performance between the blocking ring 12 and the transition pipe 9 and preventing material leakage. Both sides of the bottom of the blocking ring 14 are chamfered, which can provide a flow guide for the gas evaporated in the main tower 3 and increase the production speed of the equipment.

[0028] Embodiment 2: On the basis of Embodiment 1, the first flange 15 and the second flange 16 are adapted to each other. The other end of the transition pipe 9 is connected to the outer connecting pipe 1 through a flange. There are three groups of the first side plates 10. The three groups of the first side plates 10 are evenly distributed on the side surface of the first flange 15. The end face of the column 11 is rounded. There are three groups of the second side plates 17. The three groups of the second side plates 17 are evenly distributed on the side surface of the second flange 16.

[0029] During use, a transition pipe 9 is installed between the air outlet 2 of the main tower 3 and the outer connecting pipe 1. A first flange 15 is arranged at the air outlet 2, and a matching second flange 16 is arranged at one end of the outer connecting pipe 1 to realize the connection between the main tower 3 and the transition pipe 9. Among them, when connecting the two flanges, first, the column 11 needs to be correspondingly inserted into the guide hole and continuously pushed until the bottom block 19 contacts and abuts against the first side plate 10. At this time, the first flange 15 and the second flange 16 are attached to each other. Under the prior connection of the column 11 and the guide hole, the connection holes on the two flanges are directly corresponding, facilitating the subsequent setting of bolts, reducing the cumbersome operation of aligning the connection holes, and improving the convenience during connection.

[0030] Working principle: In actual use, the set blocking ring 14 is annular, and several blocking rings 14 are equidistantly offset from the central cylinder towards the blocking ring 12. A gap is formed between the blocking rings 14 to prevent the suction force inside the outer connecting pipe 1 from directly acting on the material itself, thereby blocking the running of liquid materials and avoiding material loss. The outer side of the abutting frame 13 is provided with a blocking ring 12, and the inner surface of the blocking ring 12 is tightly attached to and welded to the inner surface of the transition pipe 9, improving the sealing performance between the blocking ring 12 and the transition pipe 9 and preventing material leakage. Both sides of the bottom of the blocking ring 14 are processed with chamfers, which can provide a flow guide for the evaporated gas in the main tower 3 and increase the production speed of the equipment. This avoids the following problems in the prior art: Evaporators are evaporation concentration crystallization devices, generally used in wastewater treatment in industries such as industry, chemical engineering, oil extraction, pharmaceuticals, and oil drilling. With the increasingly severe environmental protection situation and the increasing requirements for energy conservation and emission reduction in recent years, evaporator equipment is used more and more frequently. However, existing evaporators often experience material leakage due to operating errors, excessive or suddenly increased vacuum degrees during use, and have low evaporation efficiency, which also affects product quality.
