In this embodiment, a first ring catch 232 is disposed at the lower end of the filter disc 231, the first ring catch 232 includes a first mounting cylinder 234 and an inner connecting plate 235, and the second elastic retaining ring 233 is mounted on the outer peripheral wall of the first mounting cylinder 234; an inner tab 235 is mounted to the lower edge of the first mounting cylinder 234 and extends inwardly; the upper end of the second mounting ring 211 is provided with a second ring buckle, the second ring buckle comprises a second mounting cylinder 236 and an external connecting plate 237, the external connecting plate 237 is mounted at the upper end of the second mounting cylinder 236 and extends outwards, the external connecting plate 237 is positioned above the internal connecting plate 235, so that the second elastic retaining ring 233 moves downwards for a preset distance first and then drives the second mounting ring 211 to move downwards, the preset distance is smaller than the distance between the middle part of the first elastic retaining ring 141 and the middle part of the second elastic retaining ring 233, and dust cannot be uniformly distributed on the filter disc 231, so that the filter disc 231 can rotate around the second ring buckle when inclined, and dust on the filter disc 231 is basically discharged completely.
In this embodiment, the thickness of the first elastic retaining ring 141 is greater than the distance from the lower bottom surface of the second elastic retaining ring 233 to the lower bottom surface of the inner connecting plate 235, in an initial state, there is a gap between the first elastic retaining ring 141 and the second mounting ring 211, there is a gap between the inner connecting plate 235 and the second mounting ring 211, and the height of the gap between the first elastic retaining ring 141 and the second mounting ring 211 is greater than the height of the gap between the inner connecting plate 235 and the second mounting ring 211, so that after the lower bottom surface of the inner connecting plate 235 contacts the upper surface of the second mounting ring 211, the first elastic retaining ring 141 has not moved to the middle position of the second elastic retaining ring 233.
In this embodiment, the cross-sectional profile of the first elastic baffle ring 141 includes a first arc section and a first connecting section that are connected end to end, the first arc section is located at the inner side of the first connecting section, and the upper half part and the lower half part of the first arc section are symmetrically arranged with respect to the horizontal plane; the joint of the upper half part and the lower half part of the first arc segment is the middle part of the first elastic baffle ring 141; the cross-sectional profile of the second elastic baffle ring 233 includes a second connecting section, a diagonal section and a second circular arc section which are sequentially connected end to end, the diagonal section is located at the outer side of the second connecting section, the outer end of the diagonal section is located at the lower side of the inner end, the second circular arc section is located at the lower side of the diagonal section and the outer side of the second connecting section, the joint of the second circular arc section and the diagonal section is the middle of the second elastic baffle ring 233, in an initial state, the upper half of the first circular arc section is in contact with the second circular arc section, so that when the dust gravity and the gas blowing action force on the filter disc 231 are not enough to overcome the elasticity of the elastic strip 213, the elastic strip 213 is restored to an original state, the second installation ring 211 is driven to push the inner connection plate 235 and the first installation cylinder 234 upwards, when the second elastic baffle ring 233 moves upwards until the middle thereof is aligned with the middle of the first elastic baffle ring 141, the first elastic baffle ring 141 drives the filter disc 231 to bounce upwards under the action of the cambered surfaces, the filter disc 231 is restored to the original state. And ensures that the filter disc 231 does not vibrate repeatedly when the automatic dust cleaning condition is not met.
In this embodiment, the refrigerant circulation pipe 17 is a spiral pipe filled with a refrigerant, two refrigerant circulation ports 15 are formed in a sidewall of the housing 14, and upper and lower ends of the spiral pipe are connected to one refrigerant circulation port 15, respectively, so that the refrigerant in the refrigerant circulation pipe 17 is circulated and refreshed, when the refrigerant in the refrigerant circulation pipe 17 is refreshed, the refrigerant is input into the refrigerant circulation pipe 17 from one refrigerant circulation port 15, and the refrigerant existing in the original refrigerant circulation pipe 17 is discharged from the other refrigerant circulation port 15.
When the device is used, the flue gas in the evaporation device 12 is introduced into the accommodating cavity of the cooling chamber from the air inlet 18 along the pipeline 13, and the flue gas after being dedusted by the dedusting mechanism is cooled and cooled under the action of the refrigerant circulating pipe 17 and then discharged from the air outlet 16. The impact force of the air flow on the filter disc 231 is gradually increased along with the gradual accumulation of the dust on the filter disc 231, so that the second elastic blocking ring 233 moves downward and presses the first elastic blocking ring 141, after the lower bottom surface of the internal connection plate 235 contacts the upper surface of the second installation ring 211, the second elastic blocking ring 233 does not move to the middle position of the first elastic blocking ring 141, the internal connection plate 235 starts to press the second installation ring 211 downward along with the continuous accumulation of the dust on the filter disc 231, and when the second elastic blocking ring 233 moves to be level with the first elastic blocking ring 141, the second installation ring 211 does not tilt substantially because the downward movement distance of the internal connection plate 235 and the second installation ring 211 is short. Afterwards, the filter disc 231 continuously moves downwards due to the blowing of the air flow and the gravity action of the dust on the filter disc 231, so that all the elastic force accumulated between the first elastic baffle ring 141 and the second elastic baffle ring 233 and the impact force of the air flow act on the second mounting ring 211, and the elastic strips 213 elastically deform, and because the elastic strips 213 are unevenly distributed, the bending range of the elastic plates at the densely distributed positions is small, the bending range of the elastic plates at the sparsely distributed positions is large, so that the second mounting ring 211 inclines, and the second mounting ring 211 inclines and then is separated from contact with the inner wall of the shell, so that the dust at the edge of the second mounting ring 211 falls into the outer side of the flexible cylinder at the position where the bending degree of the elastic strips 213 is large, namely, the dust falls into the dust collection bin. Since the dust cannot be uniformly distributed on the filter screen disc, the filter disc 231 can rotate around the second ring fastener when inclined, the dust on the filter disc 231 is basically discharged, and the discharged dust is subsequently cleaned.
Further, when the dust gravity and the blowing acting force of the air flow on the filter disc 231 are not enough to overcome the elastic force of the elastic strip 213, the elastic strip 213 returns to the original state, the second mounting ring 211 is driven to push the inner connecting plate 235 and the first mounting cylinder 234 upward, and when the second elastic retaining ring 233 moves upward until the middle part of the second elastic retaining ring 233 is aligned with the middle part of the first elastic retaining ring 141, the second elastic retaining ring 233 drives the filter disc 231 to bounce upward under the action of the second arc section and the arc surface of the first arc section, so that the filter disc 231 returns to the initial state.
Further, as shown in fig. 8, a is the maximum width of the horizontal projection of the deformed sparse-side elastic strip 213, b is the maximum width of the horizontal projection of the deformed dense-side elastic strip 213, and c is the maximum distance between the second mounting ring 211 and the inner peripheral wall of the housing when the second mounting ring 211 is inclined. The gas acts on the horizontal projection surface of the elastic strips, because the bending degree of the elastic strips on the sparse side is greater than the bending degree of the elastic strips 213 on the dense side, namely the width of a is greater than the width of b, the horizontal projection area of the elastic strips on the sparse side is greater than the projection area of the elastic strips on the dense side, and therefore the gas further acts downwards on the elastic strips 213 on the sparse side, the bending degree of the elastic strips 213 on the sparse side is further increased, namely the inclination degree of the filter disc 231 is further increased, and the slag discharging efficiency is improved.
Further, in the dust cleaning process, since the bending degree of the elastic strips 213 on the dense side is less than that of the elastic strips 213 on the sparse side, the innermost end points of the elastic strips 213 on the dense side are located above the innermost end points of the elastic strips 213 on the sparse side, that is, the lowest end of the flexible sealing film located on the elastic strips 213 on the dense side is higher than that of the flexible sealing film located on the elastic strips 213 on the dense side, so that the gas acts on the flexible sealing film 2211 on the sparse side under the guidance of the flexible sealing film 2212 on the dense side, and as the stress difference on the two sides is increased, the elastic strips 213 on the sparse side are further bent, so that the filter disc 231 is further inclined, and the dust cleaning effect on the filter disc is better.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
