Description

Technical Field

[0001] The utility model belongs to the technical field of calcium-zinc composite stabilizer production, in particular to an exhaust dust removal device for the calcium-zinc composite stabilizer capable of recovering smoke dust. Background Art

[0002] Calcium zinc composite stabilizer is synthesized by special composite process with calcium salt, zinc salt, lubricant, antioxidant as main components. It can not only replace toxic stabilizers such as lead cadmium salts and organic tin, but also has quite good thermal stability, light stability, transparency and tinting strength. When producing calcium zinc composite stabilizer, it is easy for calcium zinc composite stabilizer particles to be blown up by wind and mixed with dust in the air to form smoke. Therefore, it is necessary to intercept the calcium zinc composite stabilizer particles in the smoke through exhaust dust removal device.

[0003] However, the existing exhaust and dust removal devices for calcium-zinc composite stabilizers still have many shortcomings. First, the air inlet hood of the traditional exhaust and dust removal device is usually fixedly installed on the wall of the workshop, and its air inlet direction is fixed and cannot be flexibly adjusted according to actual needs, which may lead to poor smoke and dust collection effect in some cases; secondly, when the existing device filters the gas containing calcium-zinc composite stabilizer particles, due to the influence of gas flow, the filtered calcium-zinc composite stabilizer particles may be disturbed or even blown up again, reducing the filtering effect; finally, the existing exhaust and dust removal devices often lack a cleaning mechanism for the filter plate. After long-term use, a large amount of stabilizer particles and dust will accumulate on the filter plate, which not only affects the filtering effect but also may cause the performance of the device to decline.
