An air outlet is provided on the top of the tank, and a filter assembly is provided at the air outlet. An air outlet pipe is fixedly connected to the filter assembly. A liquid supply assembly is provided on the top of the tank. In actual use, this type of concentrator has a short contact time and small contact area between the liquid and steam, resulting in low steam utilization and poor evaporation efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a multi-level composite concentrator that can increase the contact area and contact time between the liquid and the steam and has higher working efficiency.

[0004] Therefore, this utility model is implemented using the following technical solution: A multi-level composite concentrator includes a tank body and a top cover. The upper part of the tank body is provided with a steam inlet pipe and a steam outlet pipe, and the bottom of the tank body is provided with a discharge pipe. The top cover is provided with a feed pipe and a condensate outlet pipe. The top cover and the tank body are detachably connected by several bolts. The lower end of the top cover is provided with a spiral liquid flow pipe extending into the lower part of the tank body. The upper end of the spiral liquid flow pipe is provided with a feed inlet aligned with the lower end of the feed pipe, and the lower end is provided with a discharge outlet. The outer and inner side walls of the spiral liquid flow pipe are provided with several overflow holes.

[0005] Furthermore, the upper end of the cover is equipped with a motor, the motor shaft of the motor passes through the cover and is welded with a rotating shaft, the tank body is equipped with an upward-facing barrel, the inner bottom of the barrel is fixed to the rotating shaft, the spiral liquid pipe is located in the barrel body, the barrel body is equipped with a multi-layer liquid outlet structure from top to bottom, each layer of liquid outlet structure includes liquid ejection holes evenly distributed on the barrel body.

[0006] Furthermore, the outer wall of the barrel is provided with a connecting pipe that communicates with the liquid ejection hole. The connecting pipe extends into the inner wall of the tank, and a scraper that can abut against the inner wall of the tank is welded and fixed at the lower end of the connecting pipe.

[0007] Furthermore, the diameter of the opening of the barrel gradually decreases towards the bottom of the barrel, and the inner wall of the barrel cross-section is inclined.

[0008] Furthermore, a connecting seat is provided at the center of the inner bottom of the barrel, and the connecting seat has a groove for inserting a rotating shaft. After the rotating shaft is inserted into the groove, it is fixed to the connecting seat by welding.

[0009] Furthermore, the liquid ejection hole is connected to the inner wall of the barrel by a guide arc surface, and both the liquid ejection hole and the connecting pipe are horizontal strips.

[0010] Furthermore, the outer ring of the upper cover is provided with a surrounding plate that extends downward and covers the upper end of the tank body, and multiple sealing rings are provided between the surrounding plate and the tank body.

[0011] Furthermore, several connecting rods are welded to the upper outer wall of the spiral liquid pipe, and the upper end of the connecting rods is welded and fixed to the lower end of the upper cover.

[0012] After adopting the above technical solution, because the lower end of the upper cover is equipped with a spiral liquid flow pipe extending into the lower part of the tank, the upper end of the spiral liquid flow pipe has a feed inlet aligned with the lower end of the feed pipe, and the lower end has a discharge outlet. After the liquid enters from the feed pipe, it flows into the spiral liquid flow pipe through the feed inlet, and most of the liquid flows out from the discharge outlet through the spiral liquid flow pipe. In this process, the liquid forms a multi-layer liquid flow from top to bottom through the spiral liquid flow pipe, which increases the contact area and contact time between the liquid and the steam, making the liquid evaporate faster, greatly improving the working efficiency of the concentrator, and at the same time, the utilization rate of steam is higher. When there is too much liquid in the spiral liquid flow pipe, the liquid will flow out through several overflow holes on the outer and inner walls of the spiral liquid flow pipe, preventing the spiral liquid flow pipe from being full and the liquid from falling directly to the bottom of the tank. The overflow holes are not only used for liquid overflow, but also for steam flow when the liquid level is not above the overflow hole, so that steam can enter the spiral liquid flow pipe and make the steam and liquid more fully contacted. In addition, the top cover and the tank body are detachably connected by several bolts. The spiral liquid flow pipe is located at the lower end of the top cover. After removing the top cover, the spiral liquid flow pipe can be taken out together for easy cleaning. Attached Figure Description

[0016] Referring to the attached figures, the multi-level composite concentrator provided by this utility model includes a tank body 1 and a top cover 2. A steam inlet pipe 3 and a steam outlet pipe 4 are installed on the upper part of the tank body 1, and a discharge pipe 5 is installed at the bottom of the tank body 1. A feed pipe 6 and a condensate outlet pipe 7 are installed on the top cover 2. The top cover 2 and the tank body 1 are detachably connected by several bolts 8. A spiral liquid flow pipe 9 extending into the lower part of the tank body 1 is provided at the lower end of the top cover 2, and the upper end of the spiral liquid flow pipe 9 is aligned with the lower end of the feed pipe 6. The tank has an inlet 10 and an outlet at the bottom. The outer and inner walls of the spiral liquid-discharging pipe 9 are provided with several overflow holes 11. A motor 12 is located at the top of the upper cover 2. The motor shaft of the motor 12 passes through the upper cover 2 and is welded to a rotating shaft 13. A barrel 14 with its opening facing upwards is located inside the tank body 1. The inner bottom of the barrel 14 is fixed to the rotating shaft 13. The spiral liquid-discharging pipe 9 is located inside the barrel 14. The barrel 14 has a multi-layered liquid-discharging structure from top to bottom. Each layer of the liquid-discharging structure includes a circumferential... The barrel 14 has equal distribution of liquid ejection holes 15. The outer wall of the barrel 14 has a connecting pipe 16 communicating with the liquid ejection holes 15. The connecting pipe 16 extends towards the inner wall of the barrel 14, and a scraper 17 that can abut against the inner wall of the barrel 1 is welded and fixed to the lower end of the connecting pipe 16. The diameter of the opening of the barrel 14 gradually decreases towards the bottom of the barrel 14. The inner wall of the barrel 14 has a sloping surface 18. A connecting seat 19 is provided at the center of the inner bottom of the barrel 14, and the connecting seat 19 has a groove for inserting a rotating shaft 13. After the rotating shaft 13 is inserted into the groove, it is fixed to the connecting seat 19 by welding. The liquid ejection hole 15 and the inner wall of the tank body 14 are transitioned by the flow guiding arc surface 20. The liquid ejection hole 15 and the connecting pipe 16 are both horizontal strips. The outer ring of the upper cover 2 is provided with a surrounding plate 21 that extends downward and covers the upper end of the tank body 1. Multiple sealing rings 22 are provided between the surrounding plate 21 and the tank body 1. Several connecting rods 23 are welded to the upper outer wall of the spiral liquid flow pipe 9. The upper end of the connecting rod 23 is welded to the lower end of the upper cover 2.

[0017] In this embodiment, the lower end of the upper cover 2 is provided with a spiral liquid-flowing pipe 9 extending into the lower part of the tank body 1. The upper end of the spiral liquid-flowing pipe 9 is provided with an inlet 10 aligned with the lower end of the feed pipe 6, and the lower end is provided with an outlet. After the liquid enters from the feed pipe 6, it flows into the spiral liquid-flowing pipe 9 through the inlet 10. Most of the liquid flows out from the outlet through the spiral liquid-flowing pipe 9. During this process, the liquid forms a multi-layered liquid flow from top to bottom through the spiral liquid-flowing pipe 9, which increases the contact area and contact time between the liquid and the steam, making the liquid evaporate faster and greatly improving the working efficiency of the concentrator. At the same time, the utilization rate of steam is higher. When the spiral liquid-flowing pipe 9... When there is too much liquid inside, the liquid will flow out through several overflow holes 11 on the outer and inner walls of the spiral liquid pipe 9, so as to prevent the spiral liquid pipe 9 from being full and the liquid from falling directly to the bottom of the tank body 1. The overflow holes 11 are not only used for liquid overflow, but also for steam flow when the liquid is not full. This allows steam to enter the spiral liquid pipe 9 and make the steam and liquid more fully contacted. In addition, the top cover 2 and the tank body 1 are detachably connected by several bolts 8. The spiral liquid pipe 9 is located at the lower end of the top cover 2. After removing the top cover 2, the spiral liquid pipe 9 can be taken out together, which is convenient for cleaning the spiral liquid pipe 9. After the liquid flows out from the outlet of the spiral liquid pipe 9 and / or the overflow hole 11, it enters the tank 14. After the motor 12 starts, it drives the rotating shaft 13 and the tank 14 to rotate. Under the action of centrifugal force, the liquid flows upward on the inner wall of the tank 14 and is thrown out through the throwing hole 15 to the inner wall of the tank 1. Then the liquid flows downward from the inner wall of the tank 1 with gravity, further increasing the contact time between the liquid and the steam to improve the concentration efficiency. The spiral liquid pipe 9 and the tank 14 form a multi-layer liquid flow from the inside to the outside. The connecting pipe 16 allows the liquid to be stably thrown towards the inner wall of the tank 1 after passing through the throwing hole 15 and the connecting pipe 16, preventing the liquid from falling directly into the bottom of the tank 1 after being thrown out of the throwing hole 15, thus ensuring the contact time between the liquid and the steam. The scraper 17 at the lower end of the connecting pipe 16 rotates with the tank body 14, which can scrape the liquid thrown onto the inner wall of the tank 1 by the connecting pipe 16 to be thinner, so that part of the liquid forms a thin film, and the falling film evaporation and concentration is more efficient. The diameter of the opening of the barrel 14 gradually decreases towards the bottom of the barrel 14, and the inner wall of the cross section of the barrel 14 is inclined 18, which makes it easier for the liquid to flow upward to the inner wall of the barrel 14, thereby allowing the liquid to be thrown out from the multi-layer liquid outlet structure to the inner wall of the tank 1 at different heights, so that the liquid is distributed on more inner walls of the tank 1, increasing the contact area and contact time between the liquid and the steam, thereby improving the concentration efficiency. After the rotating shaft 13 is inserted into the groove, it is fixed to the connecting seat 19 by welding, which makes the connection between the rotating shaft 13 and the barrel 14 more stable and the structure more robust. The setting of the guide arc surface 20 facilitates the flow of liquid into the ejector hole 15. The ejector hole 15 and the connecting pipe 16 are both horizontal strips, which facilitates the outflow of more liquid and avoids the accumulation of liquid in the barrel 14. The setting of the surrounding plate 21 and the sealing ring 22 increases the sealing between the top cover 2 and the tank 1. The spiral liquid pipe 9 is welded and fixed to the top cover 2 by several connecting rods 23, which makes the connection between the two more stable and the structure more robust.
