Description

Technical Field

[0001] This utility model relates to the field of flue gas recovery, specifically a centralized dust collection system for electrode shell assembly welding flue gas. Background Technology

[0002] During the electrode shell manufacturing process, welding fumes spread everywhere. The axial flow fans installed on the walls could not completely collect and exhaust them. Welders were still in the welding area, and the welding fumes drifted throughout the workshop, posing a hazard to the workshop staff. The entire workshop was shrouded in smoke.

[0003] Therefore, a dust collection system needs to be installed in the welding area. However, in the existing technology, the dust collection system is generally fixed above the welding station. When lifting and unloading the electrode shell, the dust collection system will obstruct the lifting and cause inconvenience.

[0004] Therefore, there is an urgent need to set up a fume collection system that is effective at dust collection in the welding area and is easy to move. Utility Model Content

[0005] To overcome the problems existing in the prior art, the purpose of this utility model is to provide a centralized dust collection system for welding fumes during electrode shell assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centralized dust collection system for welding fumes during electrode shell assembly, comprising a base, a rotating mechanism, a dust collection pipe, and a dust collection hood; the bottom of the dust collection pipe is rotatably connected to the base via the rotating mechanism; the dust collection hood is provided at one end of the dust collection pipe, and the rotating mechanism can drive the dust collection pipe and the dust collection hood to rotate.

[0007] The rotating mechanism is a conventional rotating structure such as a gear rotating mechanism or a crank-rocker rotating mechanism.

[0008] The present invention is further configured such that the rotation range of the rotating mechanism is 0°-180°.

[0009] The present invention is further configured such that: the dust removal pipe is Y-shaped, including a main dust removal pipe and two separate pipes, the separate pipes are connected to the main dust removal pipe, and the two separate pipes are set at a set angle at one end of the main dust removal pipe.

[0010] The present invention is further configured such that: a dust suction hood is provided at the bottom of the separation pipe, and the dust suction hood is connected to the separation pipe.

[0011] This invention is further configured such that the electrode shell assembly welding fume centralized recovery and dust collection system also includes an axial flow fan, which is connected to the end of the dust collection pipe away from the dust collection hood. This increases the dust collection area and ensures a stable connection.

[0012] The present invention is further configured such that the dust hood is a funnel-shaped dust hood that is narrow at the top and wide at the bottom.

[0013] The present invention is further configured such that: the electrode shell assembly welding fume centralized recovery and dust collection system also includes an external control system, which is electrically connected to the rotating mechanism and the axial flow fan.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] This invention features a rotatable dust collection system. The dust collection pipe and dust collection hood are rotated as a whole by a rotating device. The rotation range is 0°-180°, and the dust collection efficiency can reach more than 95%. This provides a relatively clean working environment for the staff and avoids the problem of the electrode shell being unable to be lifted and removed. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0023] Example:

[0024] like Figure 1 As shown in the preferred embodiment of this utility model, a centralized recovery and dust collection system for electrode shell assembly welding fumes includes a base 1, a rotating mechanism 2, a dust collection pipe, and a dust collection hood 5. The bottom of the dust collection pipe is rotatably connected to the base 1 via the rotating mechanism 2. The rotation range of the rotating mechanism 2 is 0°-180°. The dust collection hood 5 is installed at one end of the dust collection pipe, and the rotating mechanism 2 can drive the dust collection pipe and the dust collection hood 5 to rotate.

[0025] The dust hood 5 is a funnel-shaped dust hood that is narrower at the top and wider at the bottom. The dust hood 5 is made of Q235 ordinary cold-rolled steel plate, and its specific dimensions are made according to the specific dimensions of each piece of equipment on site.

[0026] The rotating mechanism 2 is a conventional rotating structure such as a gear rotating mechanism or a rotating disk. This embodiment uses a gear rotating mechanism. It includes a drive motor and a drive gear. A rotating connecting section is provided at the bottom of the dust removal pipe, and an internal gear ring is provided on the inner side of the rotating connecting section. The output end of the drive motor is connected to the drive gear, and the drive gear meshes with the internal gear ring. The rotation and rotation direction of the dust removal pipe are controlled by the forward and reverse rotation of the drive motor.

[0027] The dust removal pipeline is Y-shaped and includes a main dust removal pipeline 3 and two separate pipelines 4. The separate pipelines 4 are connected to the main dust removal pipeline 3, and the two separate pipelines 4 are set at a set angle at one end of the main dust removal pipeline 3.

[0028] The bottom of the separation pipe 4 is provided with a dust suction hood 5, and the dust suction hood 5 is connected to the separation pipe 4.

[0029] The electrode shell assembly welding fume centralized recovery and dust collection system also includes an axial flow fan, which is connected to the end of the dust collection pipe away from the dust collection hood 5. This increases the dust collection area and ensures a stable connection.

[0030] The electrode shell assembly welding fume centralized recovery and dust collection system also includes an external control system, which is electrically connected to the rotating mechanism 2 and the axial flow fan.

[0031] In actual use, after the assembled welding electrode shell reaches the designated assembly position, the axial flow fan is turned on, and the rotating mechanism 2 controls the dust collection hood 5 to rotate above the assembly frame, starting the welding operation. The axial flow fan draws the welding fumes below through the dust collection hood 5 and discharges them into the atmosphere. Depending on the actual working conditions, after the assembly and welding are completed, when lifting the electrode shell from the assembly frame, the rotating mechanism 2 rotates the dust collection hood 5 to the side, facilitating single-beam crane lifting operations. The entire process is convenient, fast, safe, and reliable, while also achieving excellent dust collection results.

[0032] Finally, it should be noted that the above-described embodiments only illustrate one or more implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be pointed out that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
