Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a novel pneumatic flip-type dust removal hood device. Background Art

[0002] Current steel production lines generate large amounts of harmful smoke and dust during production. The main components of this smoke include FeO, Fe2O3, H2O, and oil smoke. To reduce and eliminate the environmental pollution caused by these harmful substances, improve operating conditions, meet environmental protection requirements, and control dust in the workshop, the smoke generated by the rolling mill is drawn into a plastic-sintered plate dust collector through a sealed dust hood for purification. The dust hood structure affects dust removal efficiency, production efficiency, maintenance efficiency, and production safety.

[0003] The dust hood is an important part of the dust removal system. The structural rationality of the dust hood seriously restricts the dust removal effect. The structural rationality of the dust hood affects the equipment maintenance time, thereby improving production efficiency. In the steel production process, when it is necessary to change product specifications or for maintenance, the traditional manual flip dust hood requires the cooperation of the overhead crane operator to flip it, which increases safety hazards, affects the time for changing specifications, and restricts the output of steel. The new flip dust hood no longer requires the use of an overhead crane. The operator only needs to press the operation button to quickly flip the dust hood. Therefore, those skilled in the art have provided a new pneumatic flip dust hood device to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the present utility model is to provide a novel pneumatic flip dust hood device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The new pneumatic flip dust hood device includes:

[0012] Preferably, a connecting block is fixedly provided on the rolling mill body, and the connecting block is rotatably connected between the two side plates at the other end of the cylinder.

[0013] Preferably, a connecting groove is provided on the support plate, a connecting piece is fixed on the buffer pad, and the connecting piece is engaged in the connecting groove.

[0014] Preferably, the locking assembly includes an L-shaped part, a triangular block and a reset spring. The triangular block is fixedly connected to one end of the L-shaped part.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0030] The new pneumatic flip dust hood device includes:

[0031] A rolling mill body 1, a dust cover body 2 is rotatably connected to the rolling mill body 1, and a turning shaft 3 is fixed on both sides of the dust cover body 2;

[0032] Furthermore, a rubber layer 9 is provided on the rolling mill body 1, and the dust hood body 2 is in contact with the rubber layer 9. The provision of the rubber layer 9 can reduce the wear between the dust hood body 2 and the rolling mill body 1 when the dust hood body 2 is closed.

[0033] Cylinder 4, one end of the cylinder 4 is connected to the rolling mill body 1 through a first connecting assembly, and the output end of the cylinder 4 is connected to one end of the turning shaft 3 through a second connecting assembly. The first connecting assembly and the second connecting assembly each include two side plates 10, a first connecting plate 11 and a second connecting plate 12. The first connecting plate 11 is respectively connected to both ends of the cylinder 4. The first connecting plate 11 and the second connecting plate 12 are connected by connecting bolts 13. The two side plates 10 are fixedly connected to the second connecting plate 12. The two side plates 10 at one end of the cylinder 4 are rotatably connected to the turning shaft 3. A connecting block 14 is fixedly provided on the rolling mill body 1, and the connecting block 14 is rotatably connected between the two side plates 10 at the other end of the cylinder 4.

[0034] In the above embodiment, when the dust hood body 2 is opened, the cylinder 4 pulls the first connecting plate 11, and one end of the flip shaft 3 rotates between the two side plates 10. When the cylinder 4 pulls one end of the flip shaft 3 to move, the connecting block 14 rotates and is connected between the side plates 10, so that the cylinder 4 pulls one end of the flip shaft 3 to rotate, and the flip shaft 3 can drive the dust hood body 2 to rotate, thereby opening the dust hood body 2 and realizing rapid flipping of the dust hood body 2.

[0035] The support frame 5 is fixedly mounted on the rolling mill body 1. A support plate 6 is fixedly provided on the support frame 5. The support plate 6 is connected to the buffer pad 7 through a clamping assembly. A connecting groove 15 is provided on the support plate 6. A connecting piece 16 is fixedly provided on the buffer pad 7. The connecting piece 16 is clamped in the connecting groove 15. The clamping assembly includes an L-shaped piece 17, a triangular block 18 and a reset spring 19. The triangular block 18 is fixedly connected to one end of the L-shaped piece 17. A clamping groove 20 for the triangular block 18 to be clamped is provided on the connecting piece 16. The support plate 6 is provided with an installation groove 21 for installing the reset spring 19. The other end of the reset spring 19 is connected to the L-shaped piece 17. A first proximity switch 8 is fixedly mounted on the support plate 6.

[0036] When the dust hood body 2 is opened, it contacts and connects with the cushion 7, allowing the dust hood body 2 to operate smoothly after flipping. This makes the flipping movement of the dust hood body 2 safer and more reliable, thereby improving production efficiency, saving production costs, and eliminating safety hazards. When the dust hood body 2 contacts and connects with the cushion 7, the first proximity switch 8 controls the cylinder 4 to stop, ensuring the stability of the pneumatic flipping and effectively preventing the cylinder 4 from reaching the maximum opening and closing angle of 125° during flipping. If the dust hood body 2 exceeds 125°, the center of gravity of the dust hood body 2 will deviate, which will affect the service life of the cylinder 4.

[0037] When removing and replacing the cushion pad 7, press the L-shaped piece 17 to remove the triangular block 18 from the engaging groove 20, and then remove the connecting piece 16 from the connecting groove 15 to remove the cushion pad 7;

[0038] Then, the connecting member 16 is engaged in the connecting groove 15, and the connecting member 16 presses the triangular block 18. When the connecting member 16 is completely engaged in the connecting groove 15, the return spring 19 drives the L-shaped member 17 to move, and the triangular block 18 is engaged in the engaging groove 20, and the connecting member 16 can be engaged in the connecting groove 15.

[0039] Furthermore, limit blocks 22 are fixed on both sides of the L-shaped member 17, and limit grooves 23 for sliding connection of the limit blocks 22 are opened on both sides of the installation groove 21. When the L-shaped member 17 moves, the limit blocks 22 move in the limit grooves 23, which can limit the moving route of the L-shaped member 17 when the L-shaped member 17 moves.

[0040] A mounting plate 24 is fixedly provided on the rolling mill body 1, and a second proximity switch 25 is fixedly installed on the mounting plate 24. The setting of the mounting plate 24 facilitates the installation of the second proximity switch 25, and the second proximity switch 25 can control the cylinder 4 to stop when the dust cover body 2 is closed.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
