The working principle of the Miteqi vacuum cleaner’s pulse reverse-blow system.
Release time:2019-09-10
The dust-laden gas from the Miteqi vacuum cleaner enters the dust collector housing through the air inlet. Fine particulate matter is retained on the outer surface of the filter cartridge due to a variety of effects exerted by the cartridge itself. The purified gas then exits through the outlet port in the upper part of the filter cartridge housing. As usage time increases, more and more dust accumulates on the surface of the filter cartridge, reducing its permeability and causing the resistance of the dust collector to rise continuously. To ensure that the dust collector's resistance remains within the specified range, the pulse control unit sends signals to sequentially open the electromagnetic pulse valves, causing the compressed air stored in the air bags to be ejected through the nozzles of the blow pipes into the corresponding Venturi tubes (referred to as primary air). As the airflow passes through the Venturi tubes, it induces several times its volume of secondary air.
The dust-laden gas from the Metengqi vacuum cleaner enters the dust collector housing through the air inlet. Fine particulate matter is retained on the outer surface of the filter cartridges due to a variety of effects exerted by the cartridges themselves. The purified gas then exits through the outlet port in the upper part of the filter cartridge housing. As usage time increases, more and more dust accumulates on the surface of the filter cartridges, reducing their permeability and causing the resistance of the dust collector to rise continuously. To ensure that the collector's resistance remains within the specified range, the pulse control unit sends signals that sequentially open the electromagnetic pulse valves, allowing compressed air stored in the air bags to be ejected through the nozzles of the blow pipes into the corresponding Venturi tubes (referred to as primary air). As the airflow adjusts while passing through the Venturi tubes, it induces several times the volume of surrounding air—known as secondary air—into the filter cartridges. This causes the filter cartridges to expand rapidly. However, the reverse pulse airflow quickly dissipates its impact, causing the filter cartridges to contract sharply again. In this way, the dust adhering to the outer surfaces of the filter cartridges is dislodged and falls into the dust collection bin.
The dust collector's processing capacity remains unchanged.
Overview of the Miteqi Vacuum Cleaner Blowing System:
The composition of the blow-cleaning system is as follows: The A end of the pulse valve is connected to the compressed air reservoir, while the B end is connected to the blowpipe. The pulse valve features a back-pressure control valve, and its operational actions are commanded by the control unit. When the control unit does not output any signal, the moving core of the control valve seals the exhaust port, keeping the pulse valve in the closed state. However, when the control unit sends a signal, the back-pressure chamber of the pulse valve communicates with the atmosphere, causing the pulse valve to open. Compressed air then flows from the reservoir, passes through the pulse valve, and is ejected via small holes in the blowpipe into the Venturi tube, instantly creating positive pressure inside the filter bags and thus achieving dust removal.
