Description
Technical Field
The invention relates to the technical field of dust compactors, in particular to a method for adjusting the compaction density of a dust compactor.
Background
In the production of the light textile industry such as cotton, wool, hemp, chemical fiber and the like, a large amount of dust is usually generated, and the dust not only can cause adverse effects on the surrounding environment and the health of workers, but also can bring about potential safety hazards such as fire, explosion and the like. Therefore, in order to effectively improve the production environment of the textile industry and guarantee the production safety, dust collection equipment is needed to be used for collecting and treating the generated dust. In a common dust removing device, a dust compactor is an important component of the dust removing device, and is generally used for separating and collecting dust and short fibers in an air flow, compressing the dust and the short fibers into a relatively compact state, and discharging the compressed dust, so that the dust is effectively prevented from affecting the surrounding environment.
For example, patent publication No. CN202620917U provides a dust compactor, in which a screw shaft is disposed in a housing, a compaction speed-reducing motor is disposed on one side of the housing, an output end of the compaction speed-reducing motor is connected to one end of the screw shaft, an end cover is disposed at an outlet end of the housing via a hinge, and a weight block is disposed outside the end cover. Based on such mode of setting, the dust that gets into in this dust compactor is compressed into comparatively inseparable state under the combined action of screw shaft and end cover, struts the end cover discharge that is provided with the balancing weight again to reduced the volume of dust, and avoided the dust to fly upward at the collection in-process, in order to improve the collection efficiency of dust.
However, the existing dust compactor is difficult to adjust the compaction density. When the compaction density is too low, the cake formed by the dust has relatively large volume, is easy to scatter and has poor dust collection effect; when the compaction density is too high, the energy consumption of the compression process is high, the consumed time is long, and the dust collection efficiency is low. Therefore, how to effectively adjust the compaction density of the dust compactor in the working process so as to adapt to different working conditions still remains a problem to be solved urgently at present.
In view of the above, it is necessary to design a method for adjusting the compaction density of a dust compactor to solve the above problems.

(2) When the method is used for researching the relation among the wind pressure, the weight of the heavy hammer and the density of the pressed powder, the optimal density of the pressed powder is selected by drawing a relation curve between the weight of the heavy hammer and the density of the pressed powder under the constant wind pressure and according to the change rule of the slope in the curve and the combined action of the lowest density threshold of the pressed powder. Based on the selection mode, the shape integrity of the pressed powder cake obtained after compression can be guaranteed when the pressed powder cake is discharged from the outlet end of the dust compactor, secondary dust pollution caused by insufficient density of the powder cake after scattering is avoided, and the potential safety hazard of flammability and explosiveness caused by dust is effectively eliminated; meanwhile, the selection mode can also avoid the problems that the density of the pressed powder increases slowly and the compression rate is obviously reduced after the weight of the heavy hammer is too large, so that the weight of the heavy hammer is increased to achieve a better density improving effect, and the higher dust compression efficiency is kept.
(3) In the prior art, when the air pressure of a pipeline is small, the quantity of dust entering a dust compactor through the pipeline is small, and the density of a pressed powder obtained by compression under the same pressure condition is high; when the air pressure of the pipeline is high, the quantity of dust entering the dust compactor in the same time is increased, the density of the pressed powder obtained by compression under the same pressure condition is relatively low, the pressed powder obtained by compression under different air pressures cannot meet the requirements easily, and the compression efficiency is integrally low. The invention selects the pipe wind pressure as the adjustment signal of the compaction density, and changes the weight of the heavy hammer as the specific adjustment means, so that the compaction density of the dust compactor can be accurately and effectively adjusted in the simplest and most convenient and efficient manner, thereby effectively solving the problems and meeting the requirements of practical application.
