Environmental protection welding smoke purification device for environmental protection

Technical field

The invention belongs to the technical field of welding smoke purification devices, and more specifically, particularly relates to an environmental protection welding smoke purification device for environmental protection.

Background technique

In the welding workshop, various welding operations will produce a lot of welding fumes. If the human body inhales the welding fumes in a large amount or for a long time, it will seriously affect the health of the body. The inhalation of welding fumes into the lungs can easily lead to lung diseases, and it can also cause irritation to the workers' eyes 1. Affect eyesight, and work in a workshop full of welding fumes for a long time, causing great harm to workers' body and mind. When the concentration of welding smoke in the welding workshop is too large, the visibility of the workshop is affected, and safety accidents are likely to occur.

After searching, for example, the patent with patent number CN206862155U, a multifunctional welding fume purification device is disclosed, including a water cooling box, an air inlet, a water tank, a water pump, an air outlet, a spray pipe, an ice cube box, a reducing pipe, and water filtration A box, a rotating tube, an air outlet tube and a connecting tube, the air inlet hole is opened at the right end surface of the water cooling box, the air outlet hole is opened at the left end surface of the water cooling box, the lower end of the spray pipe is connected to a water pump, and the ice cube box is provided In the middle position of the upper end face of the water cooling box, this design achieves the purpose of water cooling of the present invention. The left end of the connecting pipe is installed on the left end face of the reducing pipe, and the lower end of the rotating pipe is fitted in the middle position of the upper end face of the water filter box. The left end of the air pipe is assembled inside the rotating pipe. This design solves the problem that the original welding smoke purifier cannot use the purified air, resulting in waste of resources. The invention is convenient to use, water-cooled and cool, has good stability and high reliability.

Another example is the patent number CN205164369U, which discloses an environmental protection device for welding smoke purification, which includes a purification cabinet, a dust box, a universal suction arm, a disinfection purification box and an electronic control cabinet. The bottom of the inner wall of the purification cabinet is installed with Dust removal box and electric control cabinet. The top left side of the dust removal box is connected to the disinfection and purification box through the top of the airflow connection pipe. The welding smoke purification environmental protection device adopts liquid dust removal technology, which can make the dust removal effect more perfect. A filter screen is installed in the middle of the cavity, which can effectively disperse the gas to be purified, generate more bubbles in the dust removal liquid, increase the contact area of the gas and the dust removal liquid, and improve the dust removal purification effect. The room has a "U" structure, which makes the contact time between the air and the disinfection board longer and the disinfection effect better.

Based on the above two patents and combining the existing technology, the inventor found that although the existing equipment can be used for conventional purification, it exists in practical applications, and the number of sedimentation chambers in the process of flue gas flow is small. As a result, the sedimentation and separation effect on the welding slag is poor, and the welding slag collection and dumping operations are also inconvenient, and the problem of poor purification of the entire device is caused by the single filtering and purification means.

Therefore, in view of this, research and improvement have been made on the existing structure and deficiencies, and an environmentally friendly welding smoke purification device for environmental protection is provided, with a view to achieving a more practical value.
