[0021] It should be noted that the terms used herein are only for describing the specific implementation modes and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0022] Unless otherwise specifically stated, the relative arrangements, numerical expressions and values of the components and steps set forth in these embodiments do not limit the scope of the present invention. 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 relationship. 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 interpreted 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 the subsequent drawings.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation terms 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.

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, an evaporator waste gas recovery device includes an intake pipe 1 with its left end connected to the evaporator. The right end of the intake pipe 1 is connected to a collection component 2, and the right end of the collection component 2 is connected to a filtration component 3. The right end of the filtration component 3 is connected to an exhaust pipe 4. Valves are installed on both the intake pipe 1 and the exhaust pipe 4. The collection component 2 includes a collection hood 21 with an opening to the right. A plurality of dust cleaning ports 215 are arranged in a circumferential and evenly spaced manner on the outer circumferential surface of the collection hood 21. A sealing ring 22 is fixedly sleeved on the outer circumferential surface of the collection hood 21. Relief openings 222 are provided at positions corresponding to the dust cleaning ports 215 on the outer side surface of the sealing ring 22. A rotating sleeve 23 is sleeved outside the sealing ring 22. The sealing cooperation between the rotating sleeve 23 and the collection hood 21 is achieved through the sealing ring 22. Dust discharge ports 232 are provided at positions corresponding to the relief openings 222 on the outer circumferential surface of the rotating sleeve 23. The filtration component 3 includes a filtration hood 35 disposed inside the collection hood 21. Dust is filtered through the filtration hood 35 on the filtration component 3, and the filtered dust drops inside the collection hood 21. When it is necessary to clean the dust, the valves on the intake pipe 1 and the exhaust pipe 4 are closed, and then the rotating sleeve 23 is rotated so that the dust discharge ports 232 are aligned with the relief openings 222 and the dust cleaning ports 215, thereby discharging the dust inside the collection hood 21, making it more convenient to clean the dust filtered by the filtration hood 35.

[0027] As Figure 2 shown, the filtration hood 35 is arranged in a hemispherical shape. The hemispherical structure has a large filtration area, and evenly distributed filtration holes are provided on the outer surface of the filtration hood 35 to filter dust.

[0028] As Figure 2 shown, the filtration component 3 further includes a second connecting pipe 33. A retaining ring 31 sleeved with the filtration hood 35 is fixed at the left end of the second connecting pipe 33 to fix the filtration hood 35. A clamping plate 32 stuck inside the right port of the collection hood 21 is fixed at a position of the second connecting pipe 33 close to the retaining ring 31. The clamping plate 32 is used for positioning connection with the collection hood 21. A second flange 34 is fixed at the right end of the second connecting pipe 33. The second connecting pipe 33 and the second flange 34 are used for connection with the exhaust pipe 4.

[0029] As Figure 3 shown, an annular groove 213 is provided on the outer circumferential surface of the collection hood 21 for limiting and installing the sealing ring 22. A plurality of clamping grooves 214 are provided at positions where the bottom of the annular groove 213 is offset from the dust cleaning ports 215 to cooperate with clamping platforms 221 to prevent the sealing ring 22 from rotating. A first connecting pipe 212 is fixed at the left end of the collection hood 21, and a first flange 211 is fixed at the left end of the first connecting pipe 212.

[0030] As Figure 4As shown, the inner side surface of the sealing ring 22 is fixed with multiple evenly arranged clamps 221 for fixing and clamping on the outer side of the collecting cover 21 to prevent rotation, and the outer diameter of the sealing ring 22 is larger than the outer diameter of the collecting cover 21. The outer diameter of the sealing ring 22 is larger than the outer diameter of the collecting cover 21 so that it can better press against the inner side surface of the rotating sleeve 23.

[0031] like Figure 5 As shown, a retaining ring 231 protruding inward is fixed to the left port edge of the rotating sleeve 23 for blocking the rightward movement of the rotating sleeve 23 when it is mounted on the outside of the collecting cover 21, and a plurality of blocking screws 233 are installed on the outer side of the rotating sleeve 23 near the right end thread and are evenly arranged in a circle. The blocking screws 233 are used to block the leftward movement of the rotating sleeve 23 when it is mounted on the outside of the collecting cover 21.

[0032] In this embodiment, the air intake pipe 1 is connected to the evaporator, and then the valves on the air intake pipe 1 and the exhaust pipe 4 are opened. At this time, the filter cover 35 filters the dust in the gas discharged from the evaporator, and the filtered dust falls on the inner side of the collecting cover 21. When the dust needs to be cleaned, the valves on the air intake pipe 1 and the exhaust pipe 4 are closed, and then the rotating sleeve 23 is rotated to align the ash discharge port 232 with the yield port 222 and the cleaning port 215 so that the dust in the collecting cover 21 is discharged, thereby completing the cleaning of the dust in the exhaust gas of the evaporator after filtering.

[0033] The above are preferred implementation modes of the present invention. Technicians in the field to which the present invention belongs can also change and modify the above implementation modes. Therefore, the present invention is not limited to the above specific implementation modes. Any obvious improvements, substitutions or modifications made by technicians in this field on the basis of the present invention belong to the protection scope of the present invention.
