Description

Technical Field

[0001] This utility model belongs to the field of steam crystallizers, and in particular relates to a descaling and cleaning component for crystallizers. Background Technology

[0002] Guided by the principles of "carbon peaking and carbon neutrality" and the call for the construction of "zero-waste cities," enterprises are rapidly advancing their efforts to reduce hazardous waste. As the core equipment for this reduction effort, the evaporator crystallizer is seeing a rapid increase in both its application scope and the number of installed units.

[0003] During long-term operation, we found that during the evaporation process of wastewater with high salt and high organic content, the inherent gap between the blades in the chamber and the cavity of the evaporator crystallizer makes it easy for condensation to form on the evaporator crystallizer, which greatly affects the heat exchange efficiency and may even lead to safety accidents in the long run. However, the existing evaporator crystallizer does not have an effective cleaning method. Utility Model Content

On opposite sides of the clearance hole, the lifting plate has longitudinally penetrating threaded holes and guide holes. The sidewalls of the lifting plate are provided with multiple concave grooves arranged at equal intervals in a fan-shaped pattern. The descaling scraper is also fan-shaped, with its mounting side corresponding to the groove. The blade side of the descaling scraper protrudes from the outside of the groove and fits against the inner wall of the crystallizer cavity.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1-4 As shown, the embodiments of this utility model include:

[0021] A descaling and cleaning assembly for a crystallizer is fitted to the inner wall of a cylindrical crystallizer cavity, including a lifting plate 1 and a descaling scraper 2.

[0022] The lifting plate 1 is cylindrical in shape, and the center of the lifting plate 1 is provided with a clearance hole 3 to avoid the axial rotation of the blade.

[0023] The lifting plate 1 is provided with a longitudinally penetrating threaded hole 4 and a guide hole 5 on two opposite sides of the clearance hole 3. Two longitudinally distributed threaded rods and guide posts are provided in the crystallizer cavity, corresponding to the threaded hole 4 and the guide hole 5 respectively. The driving end of the threaded rod is driven by a motor located on the top of the outer side of the crystallizer, so that the lifting plate 1 can move longitudinally.

[0024] The side wall of the lifting plate 1 is provided with a plurality of concave grooves 6 at equal intervals. In this application, there are 3 grooves 6 at equal intervals. The grooves 6 are distributed in a fan-shaped structure. The width of each groove 6 is 1 / 3 of the circumference of the lifting plate 1, so that it has a 360° full coverage structure.

[0025] The slide groove 6 is inclined in the horizontal direction, so that the descaling scraper 2 can move within the slide groove 6.

[0026] The longitudinal section of the groove 6 is a transversely distributed convex structure with a small-diameter opening at the outer end, which serves as a limiting function.

[0027] The mounting side of the descaling scraper 2 is correspondingly disposed in the slide groove 6, and the blade side of the descaling scraper 2 protrudes from the outside of the slide groove 6 and fits against the inner wall of the crystallizer cavity, so that the descaling scraper 2 can be stably installed on the lifting plate 1 and can achieve the descaling function.

[0028] The descaling scraper 2 is also arranged in a fan shape. The descaling scraper 2 is inclined in the horizontal direction. There are 3 descaling scrapers 2, which correspond one-to-one with 3 sliding grooves 6 to meet the needs of circumferential full-range cleaning.

[0029] The longitudinal section of the descaling scraper 2 on the mounting side is provided with a transversely distributed convex structure and slides corresponding to the slide groove 6 to ensure installation stability, while also being able to slide within the slide groove 6.

[0030] The width of the descaling scraper 2 is half the width of the groove 6. The initial position of the descaling scraper 2 is located at the top of the inner side of the crystallizer. When the threaded rod drives the lifting plate 1 to move down, the descaling scraper 2 is located at the upper part of the inclined end of the groove 6 under the crystallization effect of the inner wall of the crystallizer, that is, at the upper half position of the groove 6. It scrapes the crystals from top to bottom on the inner wall of the crystallizer. When it reaches the bottom position, the threaded rod drives in the opposite direction, and the descaling scraper 2 is located at the lower part of the inclined end of the groove 6 under gravity, that is, at the lower half position of the groove 6. It scrapes the crystals upward, thereby achieving 360° cleaning of the inner wall of the crystallizer. The half area cleaning effectively reduces the cleaning difficulty of scraping crystals, reduces driving energy consumption, and makes the cleaning operation more convenient.

[0031] In summary, the present invention discloses a descaling and cleaning component for crystallizers. By adding this cleaning component inside the crystallizer, it effectively achieves comprehensive cleaning of the crystallized inner wall of the crystallizer, effectively reduces the cleaning difficulty, and improves the convenience of cleaning.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
