3. The bag collector of claim 1, wherein the sealing assembly comprises a rotating seat (33), the rotating seat (33) is fixedly connected to a lower end of the lower cylinder (32), a push rod (34) is rotatably connected to the rotating seat (33), a bottom sealing plate (22) for sealing the lower cylinder (32) is fixedly connected to one end of the push rod (34) close to the lower cylinder (32), and a pressing spring (35) is pressed between one end of the push rod (34) away from the bottom sealing plate (22) and the lower cylinder (32).
4. A bag house dust collector with reduced emissions as claimed in claim 1, characterized in that the discharge openings (42) are provided with sealing plugs.
5. A method of using a reduced emissions baghouse as defined in any one of claims 1 to 4, comprising the steps of:
step 1, when the filter bag is in operation, air enters from the air inlet tee joint (4) and then enters into filter bags (19) on two sides through the air inlet (27), dust filtered by the filter bags (19) is gradually increased, the weight of the filter bags (19) is gradually increased, the inner ring table (25) is moved downwards due to the weight increase of the filter bags (19), the inclined surface block (30) is pulled to synchronously move by the downward movement of the inner cylinder (18), the locking rod (28) is pushed to slide by the downward movement of the inclined surface block (30), the inner ring brush (37) can be released, the inner ring brush (37) is pushed to downwardly move under the gravity action of the gravity block (10), and the ejector rod (36) pushes the bottom (22) away when the inner ring brush (37) descends to the bottom, so that dust in the filter bags (19) can be discharged from the filter bags (19);
step 2, will touch first limit switch (16) after gravity piece (10) will, first limit switch (16) triggers back to the controller feedback signal, drive lifting block (38) upward movement through controller start drive assembly, lifting block (38) upward movement rises gravity piece (10) through reset plate (7), can hang locking piece (31) on locking lever (28) after gravity piece (10) rise to certain height, carry out spacing and avoid the whereabouts, after lifting block (38) touches second limit switch (41) of upper end, drive assembly reverse drive falls lifting block (38), drive assembly stops work and then realizes resetting behind lifting block (38) touches second limit switch (41) of bottom.
