Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a concentrated water evaporator. Background Technology

[0002] Because wastewater concentrated by conventional membranes contains many impurities, the evaporated salts are hazardous products and cannot be reused. Therefore, wastewater can be desalinated through electrodialysis. The desalinated water from electrodialysis is then fed into an RO membrane system for wastewater reuse, while the concentrated water is fed into an evaporation unit to evaporate salts with fewer impurities and higher purity.

[0003] In the existing technology, due to the high salt content in the concentrate, there is a serious scaling problem in the evaporation equipment during long-term use, especially at the steam outlet. Scale can even cause blockage at the outlet, preventing steam from coming out and affecting the normal operation of the evaporation equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a concentrated water evaporator capable of descaling the interior of the evaporator.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a concentrated water evaporator, comprising an evaporation tank, a descaling component, and a drive component;

[0006] The top of the evaporator is provided with an air outlet, and the inner wall of the air outlet is provided with multiple holes in a circumferential direction.

[0007] The descaling assembly includes a push plate, a push rod, and a collar. The outer wall of the air outlet is provided with multiple grooves around its circumference, and the holes are connected to the grooves. The push plate is slidably inserted into the grooves, and the inner side is provided with multiple protrusions inserted into the holes. The push rod is connected to the outer side of the push plate. The collar is rotatably fitted onto the outer side of the air outlet, and the inner side can push the push rod to move.

[0008] The drive assembly includes a motor capable of driving the collar to rotate.

[0009] During descaling, the motor drives the collar to rotate, which in turn moves the push rod. The push rod then pushes the push plate, pushing the protrusion inserted in the hole toward the inside of the air outlet. Once the protrusion protrudes from the inner wall, it breaks up and pushes down the scale that has formed on the inner wall of the air outlet.

[0010] The beneficial effect of the above-mentioned concentrated water evaporator is that it can descale the outlet of the evaporator to avoid outlet blockage and ensure the normal operation of the evaporator.

[0011] Furthermore, the push rod is connected to the outer wall of the air outlet via a spring, and a toothed groove is provided at the end of the push rod away from the push plate;

[0012] The drive assembly also includes a rotating wheel, which is rotatably disposed and has arc-shaped teeth that can mesh with the tooth groove, and the collar can drive the rotating wheel to rotate.

[0013] After the collar drives the wheel to rotate, the arc-shaped teeth rotate accordingly and can mesh with the tooth grooves on the push rod, driving the push rod and push plate to move, so that the protrusion enters the air outlet and pushes the dirt down.

[0014] Furthermore, the drive assembly also includes a driven gear, which is rotatably disposed and connected to the rotating wheel. The inner side of the collar is provided with an internal gear ring in the circumferential direction, and the internal gear ring meshes with the driven gear.

[0015] When the collar rotates, the internal gear ring can drive the driven gear to rotate, thereby driving the rotating wheel to rotate together.

[0016] Furthermore, the drive assembly also includes a drive gear and an external gear ring. The motor is fixedly mounted, and its output shaft is connected to the drive gear. The external gear ring is circumferentially mounted on the outside of the collar, and the drive gear meshes with the external gear ring.

[0017] The motor can drive the drive gear to rotate, which in turn drives the external gear ring and collar to rotate, thereby driving the driven gear and wheel to rotate.

[0018] Furthermore, the descaling assembly also includes a scraper, a rotating shaft, and a connecting rod. The scraper is disposed inside the evaporator and fits against the inner wall of the evaporator. The rotating shaft is rotatably disposed in the middle of the evaporator and is connected to the scraper via the connecting rod.

[0019] The air outlet is located on the top side of the evaporator, and the output shaft of the motor is connected to the rotating shaft.

[0020] When the motor is working, it can also drive the rotating shaft to rotate, which in turn drives the scraper to move around in a circumferential direction through the connecting rod, scraping off the scale on the inner wall of the evaporator and descaling the inner wall of the evaporator.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] Please see Figures 1 to 3 This utility model provides a concentrated water evaporator, including an evaporator tank 10, a descaling component 20 and a drive component 30. The drive component 30 drives the descaling component 20 to remove scale from the inner wall of the evaporator tank 10.

[0031] Specifically, the evaporator 10 has an outlet 11 at its top, and the inner wall of the outlet has multiple holes circumferentially oriented. The descaling assembly 20 includes a push plate 21, a push rod 22, and a collar 23. The outer wall of the outlet 11 has multiple grooves circumferentially oriented, and the holes communicate with the grooves. The push plate 21 is slidably inserted into the grooves, and its inner side has multiple protrusions 211 inserted into the holes. The push rod 22 is connected to the outer side of the push plate 21. The collar 23 is rotatably fitted onto the outer side of the outlet 11, and its inner side can drive the push rod 22 to move. The drive assembly 30 includes a motor 31, which can drive the collar 23 to rotate.

[0032] The end of the protrusion 211 is arc-shaped, which fits the inner wall of the circular air outlet 11. When the evaporator is working normally, the protrusion 211 fills the hole, so that the inner wall of the air outlet forms a normal inner circular wall. During descaling, the motor 31 drives the collar 23 to rotate, thereby driving the push rod 22 to move. The push rod 22 pushes the push plate 21 to move, pushing the protrusion 211 inserted in the hole out of the hole. After the protrusion 211 protrudes from the inner wall, it can break up and push down the scale that has formed on the inner wall, so as to avoid outlet blockage and ensure the normal operation of the evaporator.

[0033] Specifically, push rod 22 is connected to the outer wall of air outlet 11 via spring 24, and the end of push rod 22 away from push plate 21 has a toothed groove. The drive assembly 30 also includes a rotating wheel 32 and a driven gear 33. One end face of the rotating wheel 32 is disposed on the driven gear 33, and the other end face has arc-shaped teeth that can mesh with the toothed groove. The driven gear 33 is rotatably disposed, and an internal gear ring 34 is provided circumferentially on the inner side of the collar 23, which meshes with the driven gear 33.

[0034] When the collar 23 rotates, the internal gear ring 34 drives the driven gear 33 to rotate, which in turn drives the rotating wheel 32 to rotate. The arc-shaped teeth rotate accordingly and mesh with the tooth grooves on the push rod 22, causing the push rod 22 and push plate 21 to move, allowing the protrusion 211 to enter the air outlet 11 and push down the scale. After the arc-shaped teeth disengage from the tooth grooves, the push rod 22 drives the push plate 21 to move outward under the action of the spring 24, retracting the protrusion 211. The reciprocating movement of the protrusion 211 improves the descaling effect.

[0035] Specifically, the drive assembly 30 also includes a drive gear 35 and an external gear ring 36. The motor 31 is fixedly mounted, and its output shaft is connected to the drive gear 35. The external gear ring 36 is circumferentially disposed on the outside of the collar 23, and the drive gear 35 meshes with the external gear ring 36. By driving the drive gear 35 to rotate through the motor 31, the external gear ring 36 and the collar 23 can be driven to rotate, thereby driving the driven gear 33 and the rotating wheel 32 to rotate.

[0036] In this embodiment, the vent 11 of the evaporator 10 is located on one side of the top, and the motor 31 is located above the center of the evaporator. The descaling assembly also includes a scraper 25, a rotating shaft 26, and a connecting rod 27. The scraper 25 is disposed inside the evaporator 10 and fits against the inner wall of the evaporator 10. The rotating shaft 26 is rotatably disposed in the middle of the evaporator 10 and is connected to the scraper 25 via the connecting rod 27. The output shaft of the motor 31 is connected to the rotating shaft 26. When the motor 31 is working, it can also drive the rotating shaft 26 to rotate, thereby driving the scraper 25 to move circumferentially via the connecting rod 27, scraping off the scale on the inner wall of the evaporator, thus descaling the inner wall of the evaporator.

[0037] The working principle of the above-mentioned concentrated water evaporator is as follows: the motor 31 drives the collar 23 to rotate through the driving gear 35 and the outer gear ring 36. Under the action of the inner gear ring 34 and the driven gear 33, the arc-shaped teeth and the spring 24 drive the push rod 22 and the push plate 21 to move back and forth, causing the protrusion 211 to protrude back and forth on the inner wall of the air outlet 11, thereby breaking up and pushing down the scale. At the same time, the motor 31 can also drive the scraper 25 to move on the inner wall of the evaporator 10 through the rotating shaft 26 and the connecting rod 27, scraping off the scale on the inner wall.

[0038] Using the above-mentioned concentrated water evaporator, it is possible to descale the outlet of the evaporator to avoid blockage, and also to descale the inner wall of the evaporator, ensuring the normal operation of the evaporator.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
