Description

Technical Field

[0001] The utility model relates to the technical field of evaporator cleaning equipment, in particular to a scale cleaning device for an evaporator. Background Art

[0002] An evaporator transfers the heat energy of a heat source to a medium to be evaporated, and the medium to be evaporated is vaporized and evaporated after being heated on an evaporation heat exchange surface.

[0003] The existing Chinese patent with the publication number CN104667552A discloses an evaporator with a built-in cleaning device, which includes an evaporation mechanism and an aeration device. The evaporation mechanism includes a housing and a plurality of heat exchange tubes located inside the housing. The aeration device includes an aeration pipeline and a gas supply device connected to the aeration pipeline. The evaporator can clean the scale on the surface of the heat exchange tubes in a shutdown state, and can also realize on-line cleaning during the operation of the evaporator by setting the evaporation mechanism and the aeration device into a loop.

[0004] In view of the above related technologies, it is found that after the above evaporator cleans the scale, it needs to filter and collect the filter residue through a U-shaped filter screen. After long-term accumulation, the filter screen is prone to blockage, so it often needs to be shut down for cleaning, and it is impossible to replace without shutting down, which is very inconvenient to operate, and thus reduces the efficiency of scale cleaning of the evaporator.

At the same time, it should be understood that, for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description.

The multi-head filter rack 4 includes an outer ring shell 41 and a core seat 42. The outer ring shell 41 is fixedly installed with the diversion cover group 3. The core seat 42 is rotatably installed in the outer ring shell 41, and the upper end surface of the core seat 42 is in contact with the diversion cover group 3. A number of detachable filter elements 6 are installed in the core seat 42. A drain cover group 5 is installed on the lower end surface of the core seat 42. The drain cover group 5 is fixedly connected to the outer ring shell 41. By providing the cleaning drain pipe 2 at the lower end of the evaporator housing 1, it is convenient to discharge the sewage through the cleaning drain pipe 2 after cleaning the evaporator. At the same time, by fixedly installing the diversion cover group 3 at the lower end of the cleaning drain pipe 2, the sewage in the cleaning drain pipe 2 is guided into the lower multi-head filter rack 4 through the diversion cover group 3 for filtration. By setting the structure of the multi-head filter rack 4, it is ensured that the core seat 42 can be installed through the outer ring shell 41 during use, and it is easy to install the filter elements 6 through the core seat 42 during use. In this way, when the sewage enters the multi-head filter rack 4, it can be filtered through the filter elements 6. By setting the drain cover group 5, it is ensured that the filtered sewage is stably discharged to the outside.

[0028] Refer to Figure 3 As shown in the figure, the diversion cover group 3 includes a top cover plate 31 and a connecting pipe 32. The connecting pipe 32 is provided on the upper end surface of the top cover plate 31, and the connecting pipe 32 is integrally formed with the top cover plate 31. By setting the structure of the diversion cover group 3, it is ensured that the top cover plate 31 can be connected with the cleaning drain pipe 2 through the upper connecting pipe 32 to drain the sewage during use.

[0029] Refer to Figure 3 and Figure 5As shown in the figure, the outer ring shell 41 includes an annular shell 411 and connecting ears 412. The connecting ears 412 are evenly arranged on the outer side surface of the annular shell 411, and the connecting ears 412 and the annular shell 411 are integrally formed. By setting the structure of the outer ring shell 41, it is ensured that the connecting ears 412 are arranged on the annular shell 411, which facilitates the connection and fixation with the diversion cover group 3 and the drainage cover group 5 through the connecting ears 412 during use. A sealing bearing 413 for installing the core seat 42 is arranged on the inner side surface of the annular shell 411. The outer ring of the sealing bearing 413 is fixedly connected with the annular shell 411, and the inner ring of the sealing bearing 413 is fixedly connected with the core seat 42. By setting the sealing bearing 413, it is ensured that the core seat 42 can drive the filter element 6 to rotate and adjust during use, and different filter elements 6 are moved between the connecting pipe 32 and the liquid outlet pipe 52, so that the automatic replacement of the filter element 6 can be realized. A plurality of positioning grooves 421 for installing the filter element 6 are evenly opened in the middle of the core seat 42 along the circumferential direction. An angle motor 311 is fixedly installed on the upper end surface of the top cover plate 31, and the output end of the angle motor 311 is connected to the center of the core seat 42.

By setting the structure of the drainage cover group 5, it is ensured that the liquid outlet pipe 52 can be arranged at the lower end of the bottom cover plate 51 during actual use, and the filtered sewage can be stably discharged through the liquid outlet pipe 52 during use. Outer ring frames 312 corresponding to the connecting ears 412 are fixedly installed on both the top cover plate 31 and the bottom cover plate 51. The outer ring frames 312 are fixedly connected to the connecting ears 412 by bolts. By setting the outer ring frames 312, it is ensured that the top cover plate 31 and the bottom cover plate 51 are stably connected and matched with the outer ring shell 41.

[0031] In this embodiment, during the cleaning process of the evaporator, the sewage can be stably discharged through the cleaning drain pipe. The sewage flows into the connecting pipe through the cleaning drain pipe, then enters the filter element of the multi-head filter rack, and then is discharged through the liquid outlet pipe of the drainage cover group after being filtered by the filter element. When there are more dirt and impurities in the sewage, the filter element is often blocked. Therefore, after cleaning for a period of time, the angle motor is started to drive the multi-head filter rack to rotate, so as to rotate a new filter element between the connecting pipe and the liquid outlet pipe. In this way, the new filter element can be used for filtration, and the old one can also be taken out from the mating groove for replacement.
