Description

Technical Field

[0001] The invention relates to the technical field of rust removal devices, in particular to a rapid rust removal device for a pressure vessel. Background Art

[0002] Pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. Pressure vessels are divided into reaction vessels, heat transfer vessels, separation vessels and storage and transportation vessels according to their uses. From the perspective of safety supervision, pressure vessels are classified into three categories according to their danger and hazard. Category 1 containers: low-pressure containers for non-flammable or non-toxic media and low-pressure heat transfer containers and separation containers for flammable or toxic media. Category 2 containers: medium-pressure containers for media; low-pressure containers for highly toxic media; low-pressure reaction containers and storage and transportation containers for flammable or toxic media. Category 3 containers, such as: high-pressure and ultra-high-pressure containers; low-pressure containers for highly toxic media with PV≥1.96×1055Pa·m3 and medium-pressure containers for highly toxic media; medium-pressure reaction containers for flammable or toxic media with PV≥4.9×105 (Pa·m3) (i.e.: 5000).

DETAILED DESCRIPTION

[0052] 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

The position of the upper cover body 5 can be adjusted by the arranged cylinder 4, and then the pressure vessel can be stably placed under the cooperation of the upper cover body 5 and the lower cover body 6;

[0059] A working assembly 7 is arranged between the working table 1 and the mounting plate 3;

[0060] Among them, the working component 7 includes a grinding part 71 installed between the mounting plate 3 and the lower cover body 6, and the grinding part 71 is respectively connected to a reciprocating part 72 and a cleaning part 73, the reciprocating part 72 is connected to the lower cover body 6, and the cleaning part 73 is connected to the inner surface of the mounting plate 3.

[0061] The grinding part 71 comprises:

[0062] The motor 711 is arranged below the workbench 1. A rotating shaft 712 is fixedly mounted on the output end of the motor 711. One end of the rotating shaft 712 away from the motor 711 movably passes through the bottom surface of the workbench 1 and extends to the top of the workbench 1.

[0063] The small gear 713 is located above the workbench 1 and is fixedly sleeved on the outer wall of the rotating shaft 712. The small gear 713 is meshed with a large gear 714, and the large gear 714 is rotatably sleeved in an annular groove provided on the outer wall of the lower cover 6;

[0064] The arc plate 715 is fixedly mounted on the upper surface of the large gear 714 . A slot is provided on the surface of the arc plate 715 . A sliding plate 717 is slidably provided in the slot. The sliding plate 717 is fixedly connected to the polishing plate 716 via a connecting portion.

[0065] In this embodiment, a motor cover 8 is fixedly installed on the outside of the motor 711, and the top of the motor cover 8 is fixedly installed on the bottom of the workbench 1. The installed motor cover 8 can achieve a stable installation of the motor 711 and can also achieve protection of the motor 711.

[0066] Further, the connecting part includes:

[0067] A short column 718 is fixedly mounted on the side of the sliding plate 717. The short column 718 is slidably sleeved with a hollow column 719, and the hollow column 719 is fixedly mounted on the side of the grinding plate 716.

[0068] The first spring 7120 is arranged in the hollow column 719, and one end of the first spring 7120 is fixedly installed on the left end of the short column 718, and the end of the first spring 7120 away from the short column 718 is fixedly installed on the inner wall of the hollow column 719. By setting the first spring 7120, after the grinding work is completed, the grinding plate 716 can be vibrated to shake off the debris attached to the surface, without manual cleaning, and it can also avoid affecting the later grinding effect.

[0069] During the specific implementation process, the pressure vessel is first placed in the lower cover body 6, and then the upper cover body 5 is moved downward by starting the cylinder 4 until the upper part of the pressure vessel is covered. At this time, the pressure vessel is in a stable placement state, and the rotating shaft 712 can be rotated by starting the motor 711. The small gear 713 can be rotated by rotating the rotating shaft 712, and the large gear 714 can be rotated under the action of the rotation of the small gear 713.

Since the arc plate 715 and the sliding plate 717 are arranged in a snap-fitting sliding manner, and the grinding plate 716 is fixedly installed with the sliding plate 717 through the connecting part, the grinding plate 716 can be rotated with the rotation of the large gear 714, and finally the 360° grinding purpose can be achieved. Example 2

[0070] Based on Example 1, a preferred embodiment of the pressure vessel rapid rust removal device provided by the present invention is as follows Figures 1 to 6 As shown:

[0071] The reciprocating portion 72 includes:

[0072] Auxiliary block 721, fixedly mounted on the bottom of the sliding plate 717;

[0073] The connecting column 722 is fixedly installed at the bottom of the auxiliary block 721. The bottom end of the connecting column 722 is fixedly installed with a hemispherical block 723. The hemispherical block 723 is clamped in a groove opened on the top surface of the annular plate 725. There are multiple grooves, which are evenly spaced on the top surface of the annular plate 725.

[0074] In this embodiment, a second spring 724 is fixedly installed on the top surface of the auxiliary block 721, and the top end of the second spring 724 is fixedly installed on the bottom surface of the sliding plate 717. By adopting the second spring 724, the reciprocating action of the auxiliary block 721 can be more effective, so that the final grinding plate 716 can reciprocate up and down better.

[0075] In the specific implementation process, since the auxiliary block 721 is fixedly installed with the sliding plate 717, the auxiliary block 721 can be rotated during the rotation of the sliding plate 717. Due to the setting of the connecting column 722 and the hemispherical block 723, and with the cooperation of the groove, the sliding plate 717 can be moved up and down, and finally the grinding plate 716 can be moved up and down, thereby increasing the grinding intensity and making the grinding and rust removal more thorough. Example 3

[0076] Based on Example 1, a preferred embodiment of the pressure vessel rapid rust removal device provided by the present invention is as follows Figures 1 to 6 As shown: the cleaning unit 73 includes:

[0079] In the specific implementation process, the fan blades 731 installed on the outer wall of the rotating shaft 712 can rotate during the rotation of the rotating shaft 712. The rotation of the fan blades 731 generates wind force, and the wind force blows toward the pressure vessel through the vents of the ventilation duct 732, so that the polished pressure vessel can be dust-blown, which can also promote a better polishing effect.
