DETAILED DESCRIPTION
[0022] The technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0023] The utility model provides, for example Figures 1-5 The blast furnace gas dry dust collector shown includes a main body 1. The main body 1 introduces blast furnace gas into its interior through an air inlet 2 located at the upper left end. The main body 1 then transports the dust-treated gas to a connecting pipe 8 located at the right end. An induced draft fan 6 is installed at the other end of the connecting pipe 8. The induced draft fan 6 discharges the dust-treated gas through an exhaust port 7 located at the upper end. The main body 1 uses the connecting pipe 8 at the upper front end to remove dust from the internal filter bags. Dust falling from the filter bags in the main body 1 is discharged through a slag discharge port 4 located at the lower end. L-shaped slots 14 are provided at the four corners of the inner wall. A socket frame 5 is installed at the lower end of the L-shaped slots 14. A fixing rod 11 is fixed at the four corners of the upper end of the socket frame 5. A fixing block 12 for engaging with the L-shaped slots 14 is fixed at the outer wall of the fixing rod 11. A socket rod 10 is sleeved at the inner position of the fixing rod 11. The socket rod 10 is connected to the fixing rod 11 through a rotating shaft 15 at both ends. A torsion spring 16 is installed at the outer wall of the rotating shaft 15. Multiple fixing posts 13 are distributed at the inner wall of the socket rod 10.
[0024] Blast furnace gas is guided through pipelines to the inlet 2 of the bag filter. After entering the main body 1, the blast furnace gas flows through the filter bags inside the bag filter. Tiny dust particles are trapped on the surface of the filter bags. When the dust on the filter bags accumulates to a certain extent, the pulse solenoid valve 9 opens rapidly, releasing high-pressure airflow to shake off the dust adhering to the surface of the filter bags and discharge it to the outside through the slag discharge port 4. The clean gas flows out through the filter bags. The clean gas that has undergone dust removal treatment will be discharged through the exhaust port 7 at the top of the induced draft fan 6.
[0025] like Figure 2 and Figure 5 As shown, the main body 1 is supported by a support frame 3 fixed at the lower end. The air inlet 2 delivers blast furnace gas to the interior of the main body 1. The main body 1 filters the blast furnace gas through a filter bag at the interior. The induced draft fan 6 draws the gas into the interior through the connecting pipe 8. The induced draft fan 6 discharges the filtered gas through the exhaust port 7 at the upper end. The connecting rod 10 is pressed tightly against the inner wall of the main body 1 by the force of the torsion spring 16 when the connecting frame 5 and the slag discharge port 4 are installed. When the connecting frame 5 and the slag discharge port 4 are disassembled, the angle between the connecting rod 10 and the fixing rod 11 changes.
[0026] The torsion spring 16 is installed at the outer wall position of the rotating shaft 15, and the torsion spring 16 applies an outward force to the sleeve rod 10.
[0027] As shown in Figure 2 and Figure 3 The pulse electromagnetic valve 9 releases high-pressure airflow to the filter bag, and the pulse electromagnetic valve 9 shakes off the dust on the surface of the filter bag. The discharge port 4 transports the shaken-off dust to the outside position. The sleeve frame 5 is installed with the discharge port 4 by clamping the fixing block 12 in the L-shaped clamping groove 14. The sleeve rod 10 rotates around the rotating shaft 15 and moves outward along the inner wall of the discharge port 4.
[0028] The sleeve frame 5 is installed with the discharge port 4 by the fixing block 12 and the L-shaped clamping groove 14 of the inner wall of the discharge port 4. The installation of the sleeve frame 5 and the discharge port 4 makes the sleeve rod and the fixing column 13 extend into the inside position of the main body 1. When the discharge port 4 is congested, the sleeve frame 5 is rotated, the fixing block 12 is separated from the L-shaped clamping groove 14, and the sleeve frame 5 is pulled down, so that the sleeve rod 10 rotates around the rotating shaft 15 as the center axis. When the sleeve rod 10 passes through the discharge port 4, the congestion is brought to the outside position by the fixing column 13.
[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
