Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a welding smoke purification device. Background Art

[0002] During the machining process, metal parts are connected into a whole by welding. The welding is carried out by a welding machine. During the welding process, a large amount of welding smoke may be generated, which may cause damage to the health of the operator. In the prior art, the operator is generally prevented from inhaling welding smoke by wearing a mask. At the same time, a mobile purification device can be placed at the welding operation site to perform preliminary purification of the welding smoke, reduce the welding smoke particle content in the operating environment (welding smoke contains a large amount of particulate pollutants, which will cause damage to the health of the operator after inhalation), thereby reducing the degree of damage. The purification device generally includes a movable purification box, which is equipped with a filter component and an exhaust fan. When the exhaust fan is running, the welding smoke in the external environment is inhaled and then filtered by the filter component, and then discharged, so that most of the particulate pollutants are intercepted in the purification box to achieve the purpose of purification. However, in the actual operation process, since welding usually needs to be carried out continuously at multiple locations, the purification device needs to be moved frequently. At the same time, there may be obstacles (such as other tools, auxiliary materials, etc.) at the operation site to block the movement, which ultimately leads to a long time consumption and low overall efficiency.

[0025] like Figure 1 , 2As shown, this embodiment provides a welding fume purification device, which includes a purification box 1, a vertical partition 2 is fixedly connected inside the purification box 1 to separate the purification box 1 into a purification chamber 3 and a storage chamber 4, a hose 5 located on one side of the storage chamber 4 is also fixedly connected to the partition and the hose 5 is connected to the purification chamber 3, an inlet and outlet pipe 6 connected to the storage chamber 4 is also fixedly connected to the purification box 1, one end of the hose 5 away from the vertical partition 2 is fixedly connected to a connecting pipe 7 that can be clamped with the inlet and outlet pipe 6, and the connecting pipe 7 is also fixedly connected to a cover 8 located outside the purification box 1; the hose 5 has a length that can meet the movement of the connecting pipe 7 in and out of the inlet and outlet pipe 6.

[0026] In the above embodiment, a storage chamber 4 is provided in the purification box 1, and a hose 5 is provided inside. The hose 5 has a certain length and can be pulled out or put in as the cover 8 is pulled, so that the cover 8 can be placed in more operating positions without moving the purification box 1, thereby reducing the movement frequency of the purification box 1 and the time consumed, thereby solving the problem in the prior art that the purification device needs to be frequently moved during actual use, resulting in increased time consumption and reduced overall efficiency.

[0027] Similar to the prior art, this solution is also provided with a filter assembly and an exhaust fan 9, but different from the prior art, specifically, Figure 1 As shown, the top surface of the purification box 1 is also provided with a first through frame and a second through frame respectively connected to the purification chamber 3, and the first through frame is closer to the vertical partition 2; a first filter assembly is also installed in the first through frame, a mounting cylinder 12 is also installed in the second through frame, and a second filter assembly is also installed in the mounting cylinder 12, and an exhaust fan 9 is also installed in the purification chamber 3, and an air inlet pipe 13 of the exhaust fan 9 is connected to the mounting cylinder 12, and an air outlet pipe 14 is connected to the outside of the purification box 1. When the exhaust fan 9 is running, the welding smoke enters from the cover body 8, is introduced into the hose 5, and then enters the purification chamber 3, passes through the first filter After the assembly, it passes through the second filter assembly and enters the installation cylinder 12, then enters the exhaust fan 9, and is finally discharged. In the process, it is filtered twice by the first filter assembly and the second filter assembly, intercepting most of the particulate matter, thereby achieving the purpose of purification; further, the first filter assembly and the second filter assembly in this scheme are respectively detachably installed through the first through frame and the second through frame, which is convenient for subsequent maintenance. At the same time, it also includes a first cover plate 15 and a second cover plate 16 respectively covered with the first through frame and the second through frame, so as to prevent external impurities from entering through the first through frame and the second through frame;

In particular, a heat dissipation hole 18 connected to the installation cavity can also be opened on the purification box 1 to ensure normal heat dissipation of the exhaust fan 9.

[0029] like Figure 1 As shown, in a further exemplary embodiment, the cover body 8 is arranged sideways and the lower edge is fixedly connected to the bottom plate 19. The cover body 8 arranged in this way can be larger in size (higher and wider) and can stand firmly when placed, covering a larger vertical space while not occupying too much ground area. Furthermore, the support plate 21 enables the cover body 8 to stand smoothly on the ground when it is disconnected from the purification box 1. At the same time, one end of the bottom plate 19 is arranged toward the connecting pipe 7 and a magnet block 20 is also connected thereto. In this way, when the cover body 8 is folded (that is, the hose 5 is located in the storage chamber 4, the connecting pipe 7 When engaged with the inlet and outlet pipes 6, the magnet block 20 can be attracted to the side wall of the purification box 1 (the outer shell of the purification box 1 is made of iron material), thereby helping to make the cover body 8 more stable and facilitating the movement of the purification box 1 (similar to the prior art, wheels with brakes can be installed at the bottom of the purification box 1 (consistent with the prior art, not shown) to facilitate movement and fixed position); in particular, in this solution, the outer diameter of the hose 5 is smaller than the inlet and outlet pipes 6, and the hose 5 can be smoothly pulled out or smoothly fed in by manual operation, thereby realizing the pulling out and collection of the hose 5.

[0030] In a further exemplary embodiment, Figure 1 , 3 As shown, a pair of L-shaped support plates 21 are fixedly connected in the first through frame, and the first filter assembly includes a mounting plate 22 overlapped with the two support plates 21 and a plurality of filter plates 23 fixedly connected to the mounting plate 22 (the filter plates 23 are provided with holes to achieve the filtering function), and all the filter plates 23 are against the inner ground and the two inner side walls of the purification chamber 3, and the two support plates 21 are also against the two inner side walls of the purification chamber 3, that is, the plurality of filter plates 23 are parallel to each other and three sides are against the inner wall of the purification chamber 3 (they can be in sliding contact, or leave a larger gap, and the second filter assembly is used for filtering again later). , so a small number of particles passing directly through will not affect the final purification result), so that the welding smoke needs to pass through the layers of filter plates 23 after being introduced through the hose 5 before it can enter the second filter component again; in more detail, a positioning block 24 is fixedly connected to the inner bottom surface of the purification chamber 3, and the end of all filter plates 23 facing away from the mounting plate 22 is also fixedly connected to a support plate 25, and a groove for the positioning block 24 to be pressed into the support plate 25 is provided on the support plate 25.

The outer wall of the filter cylinder 10 is provided with a plurality of filter holes located outside the mounting cylinder 12 (the filter holes may be smaller than the holes on the filter plate 23), and the filter cylinder 10 is also connected with the mounting cylinder 12 through the mounting ring 27. The support ring 26 provides a lifting basis for the mounting ring 27. After the welding smoke passes through all the filter plates 23, it enters the filter cylinder 10 through the filter holes provided on the filter cylinder 10, and then enters the mounting cylinder 12 through the mounting ring 27, enters the exhaust fan 9 and is then discharged, and is finally purified. In more detail, a positioning ring 11 is also fixedly connected to the inner bottom surface of the purification chamber 3, and the end of the filter cylinder 10 facing away from the mounting ring 27 is pressed into the positioning ring 11, so that the filter cylinder 10 can be smoothly installed, thereby facilitating the installation of the second filter assembly.
