Abstract
The present invention discloses a rotary pulse type filter dust collector, which can maintain excellent de-dusting efficiency of a low pressure pulse type filter dust collector, reduce the number of required components in order to reduce manufacturing costs, maintenance fees, and lower defect factors to provide higher reliability. The dust collector includes: a dust collector body, a number of filter bags, a moving compressed air tank, nozzles, diaphragm valves, mechanical 3-way valves, protrusions, a reduction motor and a mechanical device for driving the compressed air tank, and an inverter controller.
Claims8
A rotary pulse type filter dust collector comprising:
- a dust collector body having an intermediate plate;
- a number of filter bags arranged vertically in the dust collector body;
- a compressed air tank located inside a machine room formed on the intermediate plate, and movably mounted above the intermediate plate by means of driving means, the compressed air tank receiving compressed air introduced from the outside;
- a number of nozzles perforating the compressed air tank;
- diaphragm valves connected to the nozzles respectively and correspondingly;
- mechanical 3-way valves for driving the plurality of nozzles and diaphragm valves of the compressed air tank by predetermined groups in order to clean the corresponding filter bags, the mechanical 3-way valves of the same number as the groups being mounted in the compressed air tank;
- a number of protrusions formed on the inner walls of the machine room to change the air flow direction of the 3-way valves by pressing manipulation levers of the 3-way valves;
- a reduction motor and an mechanical transmitting device for driving the compressed air tank;
- and
- an inverter controller for controlling a cleaning interval of the dust collector by controlling the rotational speed of the driving means.
