Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and more specifically, particularly relates to an air suction hood for treating waste gas from a vulcanizing machine. Background Art

[0002] Vulcanizer is a machine that vulcanizes various rubber and plastic products. It has functions such as timed mold locking, automatic pressure replenishment, automatic temperature control, automatic timing, and time alarm. Vulcanizers are divided into three types: electric heating, steam heating, and thermal oil heating.

[0003] At present, a Chinese patent with publication number CN 107335673 A discloses a suction hood assembly and a suction box, wherein the suction hood assembly includes: an anti-outflow structure, which is arranged at the air inlet of the suction hood body; a water nozzle, which is located between the anti-outflow structure and the filter element, and is arranged corresponding to the anti-outflow structure; wherein a water tank is formed at the bottom end of the suction hood body, and the liquid falling on the anti-outflow structure can flow into the water tank under the action of gravity. The suction hood assembly provided by the present invention can effectively filter a large amount of thick smoke and hot air released by molten iron during casting and cooling by adopting the first step of water curtain filtration and the second step of filter element filtration to reduce the concentration of thick smoke, wherein the water curtain filtration can filter out most of the toxic gases and large particles, creating conditions for the filter element to reduce more than 80% of particles, thereby reducing the replacement frequency of the filter element.

[0004] Although the above patent can filter out most of the toxic gases and large particles, the suction hood described in the above patent is filtered through a water curtain and then through a filter element. This method consumes a large amount of water and requires continuous delivery. In the filtration process, the toxic gases in the air will carry water into the filter element at the same time, which is prone to chemical reactions and cause corrosion between filters. It will affect the overall filtering effect in the long run, and even the suction hood shell will be corroded. In addition, toxic gases and large particles will slowly accumulate during the filtration, which is very inconvenient to clean. The subsequent cleaning of the suction hood is not considered, and the overall method is not safe and convenient. Summary of the invention
