[0027] Reference Figures 1 to 2The anti-clogging dust filtration and collection device of this utility model includes a housing 100, a dust collection box 200, a filter screen 300, and a scraper 400. An air inlet pipe 110 is provided at the top of the housing 100, and an air outlet pipe 120 is provided at the bottom. The interior of the housing 100 is hollow. The dust collection box 200 is fixed to one side of the housing 100, and the interior of the dust collection box 200 communicates with the interior of the housing 100. A connecting plate 130 is provided between the dust collection box 200 and the housing 100. The filter screen 300... Arranged in a ring shape, the filter screen 300 is pivotally housed within the housing 100, located between the inlet pipe 110 and the outlet pipe 120. One end of the scraper 400 is connected to the end of the connecting plate 130, and the other end abuts against one side of the filter screen 300. The scraper 400 is inclined downwards from the end near the filter screen 300 toward the end near the connecting plate 130. The filter screen 300 above the scraper 400 rotates in the direction of the scraper 400 (the filter screen 300 rotates along...). Figure 1 (Rotate in the direction of the arrow).

[0028] Dust-laden gas enters the hollow housing 100 through the inlet pipe 110 at the top of the housing 100. Because the filter screen 300 is located between the inlet and outlet pipes 120, the gas first flows through the annular filter screen 300, and the dust is filtered by the filter screen 300 (the filter screen 300 continuously flows along the annular filter screen 300). Figure 1 (Rotation in the direction of the arrow) The filtered gas passes through the filter screen 300 and is discharged from the exhaust pipe 120 at the lower end of the housing 100. As filtration continues, dust gradually accumulates on the filter screen 300. At this time, the pivotable filter screen 300 starts to rotate, and the surface of the filter screen 300 and the scraper 400 that is always in contact with it generate relative motion. The dust is scraped off by the downwardly tilted scraper 400 in the relative motion. The scraped dust slides along the inclined surface of the scraper 400 to the connecting plate 130, and then enters the dust collection box 200 through the connecting channel.

[0029] In summary, the filter 300 is used to filter dust. When dust accumulates and clogs the filter 300, the pivotable filter 300 allows the filter 300 to come into contact with the scraper 400. The scraper 400 then hangs the dust clumps accumulated on the filter 300 into the dust collection box 200 for centralized treatment, thus preventing the filter 300 from becoming clogged.

[0030] In some embodiments, the connecting plate 130 and the scraper 400 are tilted at the same angle, and the inner surfaces of the connecting plate 130 and the dust collection box 200 are smoothly transitioned. The dust scraped off by the scraper 400 slides down the tilted scraper 400. Because the connecting plate 130 and the scraper 400 are tilted at the same angle, the dust does not change its direction of movement or force state when it slides from the scraper 400 to the connecting plate 130, and continues to slide directly along the inclined surface of the connecting plate 130. When the dust slides to the junction of the connecting plate 130 and the dust collection box 200, due to the smooth transition between the inner surfaces of the two, there is no physical obstruction, and the dust smoothly slides from the connecting plate 130 into the interior of the dust collection box 200, and finally deposits at the bottom of the dust collection box 200.

[0031] Furthermore, to facilitate dust handling, the dust collection box 200 includes a box body 210 and a bottom shell 220. The box body 210 and the shell 100 are integrally formed. The bottom of the box body 210 is provided with a mounting hole 211, and the inner side of the mounting hole 211 is provided with a slot 212. The end of the bottom shell 220 is open, and the outer side of the upper end of the bottom shell 220 is provided with a locking block 221. The locking block 221 and the slot 212 correspond one-to-one. The upper end of the bottom shell 220 is embedded in the mounting hole 211, and the slot 212 and the locking block 221 are engaged. During equipment assembly, align the upper end of the bottom shell 220 with the mounting hole 211 at the bottom of the housing 210, aligning the outer locking block 221 of the bottom shell 220 with the inner locking groove 212 of the mounting hole 211. Then, insert the upper end of the bottom shell 220 into the mounting hole 211 until the locking block 221 is fully engaged in the groove 212, thus fixing the bottom shell 220 to the housing 210 and forming a complete dust collection box 200. When the dust collection box 200 is full of dust, apply force outward or downward to disengage the locking block 221 from the groove 212, remove the bottom shell 220 from the mounting hole 211, and empty the dust from the bottom shell 220. After cleaning, re-insert the upper end of the bottom shell 220 into the mounting hole 211, re-engaging the locking block 221 with the groove 212. Preferably, the inner bottom wall of the housing 210 is inclined to guide the dust to concentrate and collect in the bottom shell 220 for centralized treatment.

[0032] In some embodiments, the end of the connecting plate 130 is rotatably connected to the scraper 400, and a drive motor 230 is fixedly connected to the outside of the dust collector. The drive motor 230 is fixedly connected to the end of the scraper 400 and drives the scraper 400 to pivot. When it is necessary to clean the dust on the filter screen 300, the drive motor 230 is used to drive the scraper 400 to a position that abuts against the filter screen 300 for cleaning; when cleaning is not required, the drive motor 230 is used to drive the scraper 400 to a position away from the filter screen 300 to avoid affecting the rotation of the filter screen 300.

[0033] In some embodiments, the connecting plate 130 is provided with a limiting part 131, and the scraper 400 abuts against the limiting part 131 so that the scraper 400 and the connecting plate 130 are in a straight line, and the surfaces of the scraper 400 and the filter screen 300 abut against each other. The limiting part 131 forms a mechanical block for the scraper 400, preventing it from rotating away from the filter screen 300, ensuring that the scraper 400 and the connecting plate 130 remain in a straight line; at the same time, the limiting part 131 limits the scraper 400 so that the end away from the connecting plate 130 is just in close contact with the surface of the filter screen 300, avoiding excessive gap (unable to scrape dust) or excessive tightness (wearing the filter screen 300); in subsequent use, when the scraper 400 pivots and resets, the limiting part 131 can ensure that it is in the preset position each time it resets.

[0034] In some embodiments, a rotary motor 140 is fixedly connected to the outer side of the housing 100, and a rotary shaft 141 is fixedly connected to the rotary motor 140. The rotary shaft 141 extends into the interior of the housing 100, and multiple connecting rods 142 are fixedly connected to the shaft of the rotary shaft 141. The connecting rods 142 are fixedly connected to the inner side of the filter screen 300. When it is necessary to drive the filter screen 300 to pivot, the rotary motor 140 on the outer side of the housing 100 is started; the rotary motor 140 drives the rotary shaft 141 to rotate, and the rotary shaft 141 rotates synchronously inside the housing 100; the rotary shaft 141 transmits torque to the filter screen 300 through the multiple connecting rods 142 fixed to the shaft, causing the annular filter screen 300 to pivot around the rotary shaft 141; during the pivoting process of the filter screen 300, the outer side moves relative to the fixed scraper 400, and the scraper 400 scrapes away dust; at the same time, the continuous pivoting of the filter screen 300 ensures that the filtration area is used evenly and avoids localized excessive clogging.

[0035] In some embodiments, a rotating motor 140 is fixedly connected to the outside of the housing 100, and an activated carbon adsorption mesh 121 is built into the air outlet pipe 120 to further improve the filtration effect.

[0036] In some embodiments, the housing 100 has a built-in baffle 500 located below the tamping and connecting plate 130 and above the air outlet pipe 120. One end of the baffle 500 is fixedly connected to the inner wall of the housing 100, and the other end abuts against the outer side of the lower half of the filter screen 300, thereby dividing the internal space of the housing 100 into an upper cavity 101 and a lower cavity 102. This prevents air convection between the upper cavity 101 and the lower cavity 102, ensuring that only filtered air can be discharged from the lower air outlet pipe 120. The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
