Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air purification, in particular to a compressed air purification system. Background Art
[0002] In the process of cigarette production, compressed air is widely used in equipment cleaning and maintenance, driving mechanical movement and fluid injection. For example, in the process of flavoring, tobacco is fed into the cylinder by a vibrating conveyor, and it moves toward the discharge end as the cylinder rotates by its own weight and the inclination of the cylinder. The flavoring machine uses compressed air as an injection source, and sprays it from the cylinder feed end onto the tobacco in the cylinder, so as to evenly apply flavors to the tobacco.
[0003] The compressed air pipeline system in the prior art, such as Figure 1 As shown in the figure, compressed air is produced by an air compressor, and then transmitted to each compressed air branch pipeline connected to each machine control system through a single main pipeline, so as to realize the production and transmission of compressed air. Since the pipeline system only relies on the air compressor to control the moisture content of the compressed air, and only relies on the Y-type filter in the pipeline system for simple filtration, the compressed air often contains impurities such as solid particles, oil molecules, liquid condensed water, dust, and fine particles. The moisture in the compressed air will cause water stains and smoke during the flavor injection process, weaken the aroma, and cause quality problems in the production products; solid particles, dust, fine particles and other impurities in the compressed air will be transmitted to the pneumatic diaphragm pump in the suction pipeline of the flavoring machine, causing the valve core to get stuck or debris to get stuck in the one-way valve, resulting in no flow after the pneumatic diaphragm pump is started, resulting in discontinuous production and reduced production efficiency; impurities in the compressed air will hit the inner wall of the pipeline, causing abnormal noise and vibration, causing the pipeline connection to loosen and the sealing to deteriorate, and the solid particles in the compressed air will accumulate in the pneumatic components such as the diaphragm regulating valve, diaphragm pump, nozzle, cylinder, etc., which will cause abnormal noise when the equipment is running. Therefore, impurities in the compressed air will damage the silk-making equipment, often leading to frequent failures of various components in the compressed air pipeline control system, reduced service life, reduced equipment efficiency, and affecting product quality.
[0004] Currently, in the industry, the main way to reduce the moisture content of compressed air is to modify the air compressor using large dryers, but this is costly and there are still problems with subsequent maintenance. Utility Model Content

On the other hand, it helps to reduce the failure rate and shutdown rate of pneumatic components such as pneumatic diaphragm pumps, diaphragm regulating valves, diaphragm pumps, nozzles, and cylinders, and extend the service life of pneumatic components, thereby improving production continuity and improving production efficiency.
[0006] The present application is implemented through the following technical scheme: a compressed air purification system, comprising a first valve, an air inlet pipeline, an air outlet pipeline, an air-water separator and a water receiving tray; the first valve is installed in the main pipeline of the compressed air pipeline system, and is used to form a cutoff at its installation position, so that the main pipeline is divided into a first main pipeline and a second main pipeline located on both sides of the first valve; the first end of the air inlet pipeline is communicated with and fixedly connected to the first main pipeline, and the first end of the air outlet pipeline is communicated with and fixedly connected to the second main pipeline; the input port of the air-water separator is communicated with and fixedly connected to the second end of the air inlet pipeline, the gas output port of the air-water separator is communicated with and fixedly connected to the second end of the air outlet pipeline, and the liquid output port of the air-water separator is connected to the water receiving tray.

[0016] The utility model provides a compressed air purification system with the following beneficial effects:
[0017] (1) By installing a first valve in the main pipe of the existing compressed air pipeline system to cut off, the main pipe is divided into a first main pipe and a second main pipe that are not connected to each other. By designing the air inlet pipe and the air outlet pipe to be connected to the first main pipe and the second main pipe respectively, and setting an air-water separator between the air inlet pipe and the air outlet pipe, the compressed air generated by the air compressor passes through the first main pipe and the air inlet pipe into the air-water separator.

The residual compressed air in the pipeline is blown into the air-water separator at regular intervals to ensure that there is no moisture in the pipeline, which helps to further improve the purity of the compressed air.
[0019] (3) By sequentially arranging a filter and a steam trap at the liquid outlet of the gas-water separator, the water with impurities and residual air separated from the gas-water separator is further purified, which helps to improve the purity of the water in the water receiving tray.
