Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

A bag type dust remover as shown in accompanying drawing 1-8, it comprises dust removal chamber 4, the gas blowback mechanism that is arranged on the dust removal chamber 4 top and the dust discharge mechanism that is arranged on the described dust removal chamber 4 bottom; The dust removal chamber The chamber 4 includes a flower plate 15 arranged on the top of the dust removal chamber 4, a cage frame 16 connected to the bottom surface of the flower plate 15, a filter bag 17 set on one side of the cage frame 16, and a filter bag 17 arranged in the dust removal chamber 4 The maintenance opening 8 after calculation and design on the side wall.

The flower plate 15 is fixed with a joint 18, and the lower part of the joint 18 is connected with the cage frame 16 through a screw bayonet. In this way, during maintenance, the worker only needs to pass through the inspection port 8, turn the cage frame 16 inside, and put it Just take it off, it is easy and convenient to take out the filter bag 17 without opening the top cover of the dust collector and dismantling other parts.

The gas-induced blowback mechanism is a gas-induced blowback mechanism, and the gas-induced blowback mechanism includes an air bag 1 providing a gas source and a guide tube 11 for guiding the flow of gas. The bottom of the guide tube 11 is provided with Injection holes 21, the injection holes 21 are provided with a blowing pipe 10, the bottom end of the blowing pipe 10 is connected to the blowing head and the blowing nozzle is located above the flower plate 15 and corresponding to the opening of the filter bag 17. head; the gas-induced blowback mechanism also includes an electromagnetic pulse valve 19, and the electromagnetic pulse valve 19 is located between the gas bag 1 and the guide tube 11; the gas bag 1 is a high-pressure gas bag 1; the blowing tube The upper end of 10 is provided with a first air inlet 20; the blowing head includes an upper card 13 connected to the blowing pipe 10, a tapered baffle 14 and a guide head 22 arranged at the bottom of the tapered baffle 14 , the upper part of the conical baffle 14 is connected with the upper card 13, the upper card 13 and the upper conical baffle 14 are provided with a second air inlet 23; the entrance of the air bag 1 is provided with oil A filter 2, the bottom end of the oil filter 2 is provided with a sewage outlet 3.

Using the above-mentioned gas induction blowback mechanism, three times of gas induction will be induced during the blowing process, which greatly increases the air intake.

Its working principle is as follows: the gas with dust enters the dust removal chamber 4 from the inlet 9, and the gas enters the filter bag 17 under the action of positive pressure, while the dust is blocked on the outside of the filter bag 17, after working for a certain period of time , the pulse signal generator 5 generates a signal to drive the electromagnetic pulse valve 19 to open, so that the gas in the high-pressure gas bag 1 enters the flow guide tube 11, and when the gas enters the blowing tube 10 through the flow guide tube 11, the gas is induced for the first time. The filtered gas enters the blowing pipe 10, and then the gas enters the blowing head, because the length of the blowing pipe 10 makes the bottom end in the middle of the blowing head, and the gas of the blowing pipe 10 is blown into the blowing head at this time. In the blowing head, the secondary gas induction of the gas is induced, leading more gas into the blowing head, and the gas entering the blowing head passes through the guide head 22 at the lower end, so that the gas enters the filter bag 17, because the blowing head There is a certain distance to the upper mouth of the filter bag 17, so the gas flow rate blown from the blowing head is greater than the surrounding gas, so the third induction of the gas is caused, and the air in the filter bag 17 increases instantly, causing the filter bag 17 The internal pressure is higher than the outside of the filter bag 17, forming the shaking of the filter bag 17, causing the dust to fall from the outer wall of the filter bag 17, enter the dust discharge mechanism at the bottom of the dust removal chamber 4, and be discharged through the dust discharge mechanism at the bottom of the dust collector. The dust mechanism includes a funnel 6 and an ash discharge assembly 7. The dust is collected into the funnel 6 after being shaken. Due to the high internal pressure, the dust discharge assembly 7 is used to discharge the filtered dust out of the dust removal chamber 4. The filtered clean air Exhausted from air outlet 12.
