[0001] The utility model relates to the technical field of bellows welding, in particular to a special-shaped welding machine with a water-cooled fume purifier. Background Art

[0002] Special-shaped corrugated pipe is a metal pipe with irregular shape. Different from the traditional round or square pipe, the cross-sectional shape of special-shaped corrugated pipe can be various, such as oval, triangle, polygon, etc. Special-shaped corrugated pipe will use special-shaped welding machine when welding.

[0003] When an existing special-shaped welding machine welds a special-shaped corrugated pipe, its welding gun will generate smoke. The existing special-shaped welding machine generally has a smoke purifier installed on the welding equipment of the special-shaped welding machine, which includes a shell with a purification layer installed and an exhaust pump. The generated smoke is pumped into the shell and purified through the purification layer. The gas is discharged after completion. Since the generated smoke has a high temperature, its smoke molecules will move at high speed and collide frequently, which will exert a greater driving force on the smoke particles, making it easier for the smoke particles to pass through the pores of the purification layer and escape, resulting in poor smoke purification effect. Therefore, the present application provides a special-shaped welding machine with a water-cooled smoke purifier to meet the needs. Utility Model Content

[0010] In summary, the technical effects and advantages of the utility model are:

[0011] The utility model has a reasonable structure. A water-cooled smoke purifier is arranged on the special-shaped welding machine. The smoke is cooled by water before being purified.

The lower ends of the rectangular ventilation grooves are provided with rectangular ventilation openings with narrow openings. The purified gas passes through the rectangular ventilation openings with narrow openings, which can accelerate the discharge of the airflow. The discharged gas can dissipate heat on the heat-conducting longitudinal plates, thereby improving the cooling effect of the cooling water on the smoke. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Reference Figure 1-3 The special-shaped welding machine with a water-cooled fume purifier shown in the figure comprises a first moving track 1, a second moving track 2 and a rotating moving platform 7 with a clamping tool 3, a welding gun 5 is mounted on the moving mounting block 4 of the second moving track 2, and also comprises a fume purifier 6 mounted on the moving mounting block 4, the fume purifier 6 is located above the welding gun 5, the fume purifier 6 comprises a shell 61 with a purification layer 68 inside, an air inlet pipe 62 is arranged at the upper end of the shell 61, and the air inlet end of the air inlet pipe 62 is connected to a gas collecting hood 65 located above the gun head of the welding gun 5. The air outlet end of the air inlet pipe 62 is located in the inner cavity of the shell 61 and is connected to the air inlet end of the air pump 67. A cooling water tank is arranged between the air pump 67 and the purification layer 68. The air outlet end of the air pump 67 passes through the inner cavity of the cooling water tank and is connected to the aeration pipe 612. An air guide pipe 611 is arranged through the cooling water tank. The upper end of the air guide pipe 611 is communicated with the inner cavity of the cooling water tank. A waterproof and breathable membrane layer is arranged in the air inlet end cavity of the air guide pipe 611. The lower end of the air guide pipe 611 is located below the cooling water tank. An air outlet pipe 63 is arranged at the lower end of the shell 61.

[0020] The smoke purifier is directly mounted on the mobile mounting block 4, and can directly extract the smoke generated at the welding point of the welding gun 5 through the operation of the vacuum pump 67, so that the smoke gas is purified by the purification layer 68 and then discharged;

[0021] A cooling water tank is provided, which is filled with cooling water. The smoke gas with heat is distributed into the cooling water through the aeration pipe 612 for heat dissipation treatment. The cooled gas is discharged to the bottom through the air guide pipe 611, and is purified by the purification layer 68 and then discharged through the outlet pipe 63. By cooling the smoke before purifying, when the smoke gas is cooled, the kinetic energy of the gas molecules is reduced, resulting in a decrease in their speed and collision frequency, thereby reducing the driving force of the gas molecules on the particles. At the same time, the diffusion rate of the gas molecules is also reduced, reducing the possibility of the particles diffusing and escaping from the filter surface, thereby improving the purification effect of the purification layer 68 on the smoke;

[0022] A waterproof and breathable membrane layer is arranged in the air inlet end cavity of the air guide tube 611 to prevent the water in the cooling water tank from being discharged from the air guide tube 611 due to shaking when the welding gun 5 moves.

[0023] It should be noted that the purification layer 68 is composed of a pre-filter layer, a main filter layer, a HEPA filter layer and an activated carbon layer from top to bottom.

[0024] As a preferred implementation in this embodiment, Figure 3 As shown, the cooling water tank includes two heat-conducting longitudinal plates 69 fixedly embedded on the side of the shell 61 and two heat-insulating transverse plates 610 located between the two heat-conducting longitudinal plates 69 and arranged up and down. The shell 61 is made of heat-insulating material.

[0025] The heat in the cooling water is removed through the heat-conducting longitudinal plates 69 arranged at both sides of the cooling water tank, so as to achieve sustainable and continuous heat dissipation of the smoke by the cooling water;

[0026] The heat-insulating cross plate 610 and the shell 61 are made of heat-insulating materials to prevent the gas inside the shell 61 from exchanging heat with the outside world, which would cause the smoke gas to heat up after being cooled and affect the purification effect. At the same time, the heat-insulating cross plate 610 can prevent the heat of the cooling water from being conducted downward (downward conduction would cause the gas in the gap between the cooling water tank and the purification layer 68 to heat up, thereby causing the smoke gas discharged into the gap to heat up after being cooled, affecting the subsequent purification effect).

[0027] It should be noted that a receiving chamber for receiving cooling water is formed between the two heat-conducting longitudinal plates 69 , the two heat-insulating transverse plates 610 and the inner wall of the shell.

[0028] As a preferred implementation in this embodiment, Figure 2 As shown, two air outlet pipes 63 are provided, and the air outlets of the two air outlet pipes 63 are located above the corresponding heat-conducting longitudinal plates 69 and connected to the air inlet ends of the corresponding rectangular ventilation grooves 64. The lower ends of the rectangular ventilation grooves 64 are provided with rectangular ventilation openings with narrow openings.

[0029] The purified gas passes through the rectangular ventilation openings arranged at the narrow mouth, which can accelerate the discharge of the airflow. The discharged gas can dissipate heat to the heat-conducting longitudinal plate 69, thereby improving the cooling effect of the cooling water on the smoke.

[0030] As a preferred implementation in this embodiment, Figure 2 and Figure 3 As shown, a plurality of heat dissipation fins are vertically arranged on the outer walls of the two heat-conducting longitudinal plates 69 .

[0031] The heat dissipation fins can increase the contact area with the gas, thereby accelerating the heat dissipation of the cooling water. The vertical arrangement of the heat dissipation fins is parallel to the gas discharged from the gas outlet pipe 63, which is beneficial to the heat dissipation of the discharged gas to the heat dissipation fins.

[0032] As a preferred implementation in this embodiment, Figure 2 As shown, a detachable material receiving bottle 66 is installed on the U-shaped portion of the air outlet pipe 63.

[0033] The material receiving bottle 66 is used to receive materials, which may be liquid or dust, to prevent the inner cavity of the U-shaped portion of the air outlet pipe 63 from being blocked, thereby preventing the gas from being discharged from the air outlet of the air outlet pipe 64 .

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
