Description

Technical Field

[0001] This utility model relates to the field of fume collection technology, and in particular to a workshop welding fume collection device. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes various energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in a variety of environments, such as outdoors, underwater, and in space. Regardless of the location, welding can pose dangers to operators, so appropriate protective measures must be taken. Potential injuries from welding include burns, electric shock, vision impairment, inhalation of toxic gases, and excessive ultraviolet radiation. Welding workshops generate various toxic and harmful gases during product processing, posing immeasurable harm to human health. A good welding workshop fume collection device can effectively remove welding fumes and degrade the tarry smell and various toxic and harmful gases.

[0003] However, existing fume hoods are fixed at a certain height. Since welding fumes tend to diffuse upwards due to high temperatures, if the fume hood is fixed at a certain height, it may be necessary to wait for the fumes to rise to the hood opening before they can be collected. This causes some of the fumes to escape into the environment during the diffusion process, affecting the collection effect. In order to cover a larger height range, the fixed hood may need to increase the ventilation volume or the size of the hood opening, resulting in increased energy consumption. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a workshop welding fume collection device that effectively solves the problems of some fumes escaping into the environment during diffusion, affecting the collection effect, and the need to increase the ventilation volume or hood size of the fixed hood to cover a larger height range, leading to increased energy consumption.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A workshop welding fume collection device includes a base with a supporting structure. The supporting structure includes a rotatable active rotating rod, one end of which is rotatably connected to an active support rod. A mounting plate is also provided at the upper end of the base, with the active support rod rotatably mounted at one end of the mounting plate. Several auxiliary rotating rods corresponding to the active rotating rod are rotatably connected to the base, one end of which is rotatably connected to an auxiliary support rod. The auxiliary support rods are distributed and rotatably mounted on the mounting plate. An adjustment structure is provided on the mounting plate, which can drive a mounting frame mounted on the mounting plate. A fume hood is mounted at one end of the mounting frame.

[0007] Preferably, the supporting structure further includes a motor mounted on the base, the output end of which is fixedly connected to an active rotating rod, and the length of the active rotating rod is consistent with the length of the auxiliary rotating rod.

[0008] Preferably, the adjustment structure includes a rotating column rotatably mounted on the mounting plate, the upper end of the rotating column being fixedly mounted on the mounting frame, a worm gear being fixedly connected to the rotating column, and a worm engaging with the worm gear being rotatably connected to the mounting plate.

[0009] Preferably, a filter plate is provided at the lower inlet of the smoke collection hood, and a smoking pipe for gravity smoking is provided at the upper outlet of the smoke collection hood.

[0010] Preferably, the lower end of the mounting bracket is provided with ball bearings that are slidably connected to the upper surface of the mounting plate.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. This utility model, by setting up a supporting structure, uses a mounting plate to drive the smoke collection hood to move up and down reciprocally. It directly captures the smoke when it is first generated (high temperature, not yet diffused), reducing the diffusion range caused by thermal buoyancy, covering the already risen smoke layer, and forming a "three-dimensional capture zone". During the reciprocating motion, the air around the hood will flow periodically due to inertia, which can form an additional "traction airflow" to "suck" the horizontally diffused smoke into the hood, making up for the limitations of fixed hoods that rely solely on negative pressure ventilation.

[0013] 2. By setting an adjustment structure, the mounting frame is rotated, thereby changing the horizontal orientation of the smoke hood, ensuring concentrated collection of smoke and improving the collection effect. Attached Figure Description

Detailed Implementation

[0019] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-4 As shown, a workshop welding fume collection device includes a base 1, on which a supporting structure is provided. The supporting structure includes a rotatable active rotating rod 2, one end of which is rotatably connected to an active support rod 3. The upper end of the base 1 is also provided with a mounting plate 4, and the active support rod 3 is rotatably mounted on one end of the mounting plate 4. Several auxiliary rotating rods 9 corresponding to the active rotating rod 2 are also rotatably connected to the base 1. One end of each auxiliary rotating rod 9 is rotatably connected to an auxiliary support rod 10, which is rotatably distributed on the mounting plate 4. The mounting plate 4 is provided with an adjustment structure, which can drive a mounting frame 5 mounted on the mounting plate 4. One end of the mounting frame 5 is equipped with a fume hood 6.

[0021] In use, the supporting structure operates by rotating the active rotating rod 2, which in turn drives the active support rod 3 to swing. This swinging motion, in conjunction with the active support rod 3, causes the mounting plate 4 to move up and down. During this movement, auxiliary rotating rods 9 at the other ends of the mounting plate 4, along with auxiliary support rods 10, provide limiting and support, enabling the mounting plate 4 to move vertically back and forth. This movement, in turn, causes the smoke collection hood 6 to reciprocate up and down, directly capturing the smoke as it is first generated (high temperature, not yet diffused), reducing the diffusion range caused by thermal buoyancy, and covering the already risen smoke layer to form a "three-dimensional capture zone." During the reciprocating motion, the air around the smoke collection hood 6 experiences periodic flow due to inertia, creating an additional "traction airflow" that "sucks in" the laterally diffused smoke. Inside the hood, the limitation of the smoke collection hood 6 relying solely on negative pressure ventilation is overcome. At the same time, the mounting frame 5 can be rotated by controlling and adjusting the operation of the structure, thereby changing the horizontal orientation of the smoke collection hood 6, ensuring the concentrated collection of smoke and improving the collection effect.

[0022] The supporting structure also includes a motor 8 mounted on the base 1. The output end of the motor 8 is fixedly connected to an active rotating rod 2, and the length of the active rotating rod 2 is consistent with the length of the auxiliary rotating rod 9.

[0023] like Figure 2As shown, when motor 8 is working, the output end of motor 8 drives the active rotating rod 2 to rotate, and the active rotating rod 2 drives the auxiliary rotating rod 9 to deflect up and down. The length of the active rotating rod 2 is consistent with the length of the auxiliary rotating rod 9, as well as the lengths of the active support rod 3 and the auxiliary support rod 10, to ensure the smooth vertical reciprocating motion of the mounting plate 4.

[0024] The adjustment structure includes a rotating column 14 rotatably mounted on the mounting plate 4, the upper end of the rotating column 14 being fixedly mounted on the mounting frame 5, a worm gear 13 being fixedly connected to the rotating column 14, and a worm 12 meshing with the worm gear 13 being rotatably connected to the mounting plate 4.

[0025] like Figure 3 As shown, a handle 11 is provided at one end of the worm gear 12. The handle 11 drives the worm gear 12 to rotate, which in turn drives the worm wheel 13 to rotate. The worm wheel 13 drives the rotating column 14 to rotate, and the rotating column 14 drives the mounting plate 4 to adjust its horizontal position during rotation.

[0026] A filter plate 15 is provided at the lower inlet of the smoke hood 6, and a smoking pipe 7 for gravity smoking is provided at the upper outlet of the smoke hood 6.

[0027] like Figure 4 As shown, the smoke extraction pipe 7 can be connected to an external smoke extraction device. The smoke extraction device uses the smoke extraction pipe 7 to generate negative pressure on the smoke collection hood 6. The negative pressure inside the smoke collection hood 6 can filter the smoke through the filter plate 15 and then collect and discharge it.

[0028] The lower end of the mounting bracket 5 is provided with ball bearings 16 that are slidably connected to the upper surface of the mounting plate 4.

[0029] like Figure 4 As shown, the lower end of the mounting bracket 5 is provided with a ball bearing 16, which facilitates the mounting bracket 5 to roll along the upper surface of the mounting plate 4, thereby changing the horizontal orientation of the smoke hood 6.

[0030] The working process of this utility model is as follows: When this utility model is in use, the motor 8 works, and the output end of the motor 8 drives the active rotating rod 2 to rotate. The active rotating rod 2 drives the auxiliary rotating rod 9 to deflect up and down. The active rotating rod 2, together with the active support rod 3, drives the mounting plate 4 to move up and down during the swinging process. During the up and down movement of the mounting plate 4, the auxiliary rotating rods 9 at the other ends of the mounting plate 4, together with the auxiliary support rods 10, play a role in limiting and supporting the mounting plate 4, realizing the vertical reciprocating up and down movement of the mounting plate 4. The mounting plate 4 drives the smoke collection hood 6 to move up and down reciprocatingly. When the smoke is first generated (high temperature, not diffused), it is directly captured, reducing the diffusion range caused by thermal buoyancy, covering the already risen smoke layer, forming a "three-dimensional capture zone". During the reciprocating movement, the air around the hood generates periodic flow due to inertia, which can form an additional "traction airflow", "sucking" the horizontally diffused smoke into the hood, making up for the limitation of the smoke collection hood 6 relying solely on negative pressure ventilation.

[0031] At the same time, the worm gear 12 is driven to rotate by the handle 11, the worm gear 12 drives the worm wheel 13 to rotate, the worm wheel 13 drives the rotating column 14 to rotate, and the rotating column 14 drives the mounting plate 4 to adjust its horizontal position during the rotation, thereby changing the horizontal position of the smoke hood 6, ensuring the concentrated collection of smoke and improving the collection effect.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
