Description

Technical Field

[0001] The invention relates to the technical field of powder spraying lines, in particular to a dust treatment system for powder spraying lines. Background Art

[0002] In the powder spraying line operation, the filter components of the dust treatment system have long faced the technical problem of inconvenient cleaning, which seriously affects the equipment operation efficiency and maintenance costs. The main defects of traditional technology are reflected in the following aspects.

[0003] The filter bags of existing bag filters (such as corrugated frame membranes and filter vertical belts) usually adopt a fixed installation structure, which needs to be completely disassembled for cleaning, which is time-consuming and requires shutdown operation, resulting in interruption of the production line.

[0004] At the same time, traditional filter cleaning relies on manual knocking or a fixed-frequency back-blowing device, and the removal rate of adhesive dust (such as powder with humidity > 60%) is less than 70%. Residual dust can easily clog the filter holes, reducing the filtration efficiency (the document "Industrial Dust Removal Technology" points out that the system pressure difference increases by more than 50% after the filter is clogged); and the multi-layer filtration structure (such as the three-layer pleated design of the filter vertical belt) has a narrow internal gap, and it is difficult to reach deep dust by manual cleaning. At the same time, when the filtration equipment is turned on, the residue can easily cause secondary dust.

[0005] In summary: the filtering components of the existing dust treatment systems have significant deficiencies in cleaning efficiency, degree of automation and ease of maintenance, resulting in high equipment operating costs and frequent shutdowns, which seriously restrict the continuous production capacity of the powder spraying line; in response to the above problems, the present invention proposes a dust treatment system for a powder spraying line, which achieves efficient cleaning and maintenance-free maintenance of the filtering components through a dynamic knocking unit and a resistance design.

And a filter belt 9 movably penetrates through both the extended bottom box 10 and the exhaust frame opening 6. And a plurality of mounting openings 11 are arranged at equal intervals on the filter belt 9. And filter net strips 901 are arranged in each mounting opening 11. On both sides of each mounting opening 11, communicating sinking grooves 12 are opened. On both sides of each filter net strip 901, extended side blocks 902 are fixedly connected. And vibration springs two 903 are fixedly installed between both sides of the extended side blocks 902 and the sinking grooves 12. Support side frames 504 are fixedly connected between both sides of the fixed top cover 501 and the base 1; through the above structure, the filter net strips 901 are made of polyester fiber, with a dense structure with a pore diameter of 0.5mm - 1.0mm, for secondary interception of escaping dust; at the same time, when it is necessary to clean the filter net strips 901, the corresponding filter net strips 901 can be moved into the dust collection assembly 5 by the movement of the filter belt 9; at the same time, when the rotating main shaft 801 rotates, it can drive the knocking unit to rotate and make it collide with the corresponding filter net strips 901, and then through the vibration effect, the cleaning of the filter net strips 901 is realized, so that it always has a good filtering effect; specifically, the knocking end block 804, through the cooperation of the vibration spring one 806 and the rolling ball 807, triggers an impact with an amplitude of 5mm - 10mm every 3 - 5 seconds, effectively shaking off the dust on the filter screen surface.

[0046] Further, an air inlet 402 is fixedly communicated on one side of the spiral dust collector 4, and the air inlet 402 can be communicated with an external dust suction pipeline. A support ring frame 401 is fixedly installed on the outer wall of the spiral dust collector 4, and the bottom end of the support ring frame 401 is fixedly connected to the surface of the base 1.

[0049] At the same time, it should be noted that: the surface of the filter vertical belt 13 is provided with a hydrophobic coating, which can prevent high-humidity dust from adhering to improve the filtering effect on the air.

[0050] Furthermore, an extension end frame 905, a pair of mounting cross plates 908 and a pair of abutting side frames 307 are fixedly installed on the outer wall of one side of the small bag dust collector 3, and the extension end frame 905 is a U-shaped structure, and two pairs of fixed blocks are fixedly installed on the bottom side of the fixed top cover 501, and four tensioning rollers 904 are rotatably installed on the extension end frame 905 and the two pairs of fixed blocks. The filter ring belt 9 is sleeved on the outside of the four tensioning rollers 904, and the surfaces of the two mounting cross plates 908 are fixedly installed with retarding motors 907, and the output shafts of the two retarding motors 907 are connected to the The tensioning roller 904 is fixedly connected, and the output shafts of the two retarding motors 907 are fixed with cams 906. The end of the abutting side frame 307 is set to a rounded end 308, and the cam 906 is used to abut against the rounded end 308; through the above structure, when the retarding motor 907 is running and cooperates with the tensioning roller 904 to drive the filter ring belt 9 to rotate, it can drive the cam 906 to rotate, and use the rotating cam 906 to keep a constant frequency to abut against the abutting side frame 307 on one side, and cooperate with the set vibration spring three 306 to drive the top plate 301 to move back and forth.

[0051] Furthermore, movable wheel groups 2 are fixedly installed at the bottom corners of the base 1, and the movable wheel groups 2 specifically adopt universal wheels with brake functions; the movable wheel groups 2 are arranged to facilitate the movement of the system, thereby improving the flexibility of the system when used.

[0052] The specific working method is as follows: When in use, the dusty gas enters the spiral dust collector 4 through the air inlet 402. Most of the dust in the air directly falls into the dust collection assembly 5 through the bottom of the spiral dust collector 4. The air filtered by the spiral dust collector 4 enters the small bag-type dust collector 3 and is secondarily filtered through a plurality of filter hanging belts 13. The air after secondary filtration passes through the exhaust frame opening 6 and is discharged through the protective net cover 601. At the same time, the filter mesh strip 901 is made of polyester fiber. When the air passes through the dense structure with a pore diameter of 0.5 - 1.0 mm, final filtration treatment is carried out to secondarily intercept the escaping dust.

[0053] When it is necessary to clean the filter mesh strip 901, the corresponding filter mesh strip 901 can be moved into the dust collection assembly 5 by the movement of the filter ring belt 9. At the same time, when the rotating main shaft 801 rotates, it can drive the knocking unit to rotate and make it collide with the corresponding filter mesh strip 901. Then, by using the vibration effect, the cleaning of the filter mesh strip 901 is realized, so that it always has a good filtering effect. Specifically, the knocking end block 804, through the synergistic effect of the vibration spring 806 and the rolling ball 807, triggers an impact with an amplitude of 5 mm - 10 mm every 3 - 5 seconds, effectively shaking off the dust on the surface of the filter mesh. When the slow-speed motor 907 operates and drives the filter ring belt 9 to rotate in cooperation with the tensioning roller 904, it can drive the cam 906 to rotate, and the rotating cam 906 regularly abuts against the abutting side frame 307 on one side. Under the action of the support bracket 101 and the cylindrical end 304, it is ensured that the top plate 301 can move along the axial direction of the cylindrical end 304, thereby realizing driving a plurality of filter hanging belts 13 to shake and realizing the cleaning of the filter hanging belts 13.

[0054] At the same time, the final drive motor 8 drives the rotating main shaft 801 to rotate. When the rotating main shaft 801 drives the auger blade 802 to rotate, it can convey the dust in the semi-circular bottom plate 503. The provided knocking unit, namely the knocking end block 804 and the rolling ball 807, can abut against the inclined plates 505 on both sides when following the subsequent rotation of the rotating main shaft 801, and cooperate with the provided corrugated strip film 502 to make the inclined plates 505 vibrate, thereby facilitating the dust on the inclined plates 505 to slide onto the semi-circular bottom plate 503, and further facilitating the subsequent discharge of the dust.

[0055] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather should be accorded the widest scope consistent with the principles and novel features disclosed herein.
