Detailed ways

Referring to Figure 1, the utility model includes a pulse bag filter 1, an intermediate connecting plate 3, a discharge gate 6, a frame 5 and a fan 8, and the pulse bag filter 1 is fixedly connected with the frame 5, and the pulse bag filter The dust collector 1 is airtightly connected with the iron powder outlet of the steel bar straightening machine 4 through the intermediate connection plate 3, and the discharge gate 6 is welded under the dust collection funnel of the pulse bag dust collector.

Referring to Fig. 1, Fig. 4 and Fig. 5, a pulsation device 9 is provided at the outlet of the pulse bag filter 1, and the pulsation device 9 includes a pulsation cylinder 91, a rotating blade 92, a pulsation drive motor 93, a coupling 94 and The rotating blade shaft seat 95 is fixed on the outer wall of the pulsating cylinder 91, the spiral rotating blade 92 is installed in the pulsating cylinder 91 through the rotating blade shaft seat 95, and one end of the rotating blade 92 is connected through the coupling The device 94 is connected with the pulse drive motor 93.

Referring to Fig. 2 and Fig. 3, each filter bag 2 of the pulse bag filter 1 is provided with a fixed support frame and a movable support frame. The fixed support frame is a cylindrical structure composed of fixed support rods 22 fixedly connected to the filter bag. The movable support frame is a cage-like structure that is movably fitted into the filter bag, and is composed of a movable support rod 23 and a return spring expansion ring 24. Back-moving spring ring 24 is made up of center ring 26 and elastic reset rod 25, and elastic reset rod 25 is evenly distributed radially on the ring body of central ring 26, and the middle part of elastic reset rod 25 is provided with reset spring 251, and movable support rod 23 axially It is arranged between the two spring expansion rings 24, and its two ends are respectively hinged with the elastic return rod 25 outer ends of the upper and lower return spring expansion rings 4 (or one end thereof is fixed on the end face of the cylindrical fixed support frame). Elastic reset rods 25 can be provided with 3 to 12 as appropriate, and movable support rods 23 are evenly arranged between 22 fixed support rods.

The working process of the utility model is as follows. When the steel bar straightening machine 4 is working, the pulse bag filter 1 is opened, and the iron powder gas in the steel bar straightening machine 4 enters the pulse bag filter 1 under the action of the fan 8 attraction. The lower part of the box is evenly distributed to each filter bag 2 after passing through the deflector, the dust is intercepted on the outer surface of the filter bag 2, the gas passes through the filter bag 2, and is discharged from the outlet of the fan 8 through the exhaust channel of the dust collector, including During the process of purifying the dust gas through the filter bag 2, more and more dust is accumulated on the filter bag 2 with the increase of time, which increases the resistance of the filter bag 2, resulting in a gradual decrease in the processing air volume. In order to work normally, the resistance should be controlled Within a certain range (140--170 mm water column), the filter bag must be cleaned of dust. When cleaning the dust, the pulsating drive motor 93 is started, and the pulsating drive motor 93 drives the rotating blade 92 to rotate in the pulsating cylinder 91, which can be cut off quickly. , Open the airflow through the filter bag 2, and form a pulsating wind in the filter bag area. Under the action of the pulsating wind pressure, the elastic reset rod of the reset spring expands the ring to drive the movable support rod to move synchronously with the filter bag, thus increasing the movement of the filter bag range, and play the role of auxiliary mechanical impact, the dust adsorbed on the filter bag 2 is separated from the surface of the filter bag 2, and falls into the ash hopper. When the dust in the ash hopper needs to be cleaned, the discharge gate 6 is opened, and the dust is discharged The gate 6 falls into the discharge cart 7 .
