Description

Technical Field

[0002] Chemical equipment is a part of chemical machinery. Chemical machinery includes two parts. One is chemical machinery, which mainly refers to equipment such as fans, compressors, various pumps for fluid transportation. Its main components are moving machinery, generally called chemical machinery; the second is chemical equipment, which mainly refers to machinery with static components, such as separation equipment such as towers, containers, reactor equipment, etc., sometimes also called non-standard equipment. In chemical equipment, especially incineration equipment or drying equipment, it is necessary to adjust the gas flow entering through the air port in order to control the amount of gas required in the incineration or drying process, and it is necessary to aim the incoming gas at the burning flame or drying chamber to make it react more quickly and easier to control.

[0003] The patent specification with announcement number CN202120197483.4 discloses a new type of air inlet, "including a fan casing, a fan impeller is arranged in the middle of the fan casing, a rotating shaft is passed through the middle of the fan impeller, and an air inlet body is respectively arranged at both ends of the fan casing, and an air guide ring is arranged in the air inlet body, the air guide ring is a trumpet-shaped structure, and one end of the air guide ring is fixed to the outer wall of the air inlet body by welding, and the other end of the air guide ring is inserted into one end of the fan impeller, and a fence is arranged on the end of the air guide ring close to the fan impeller. The new air inlet adopts the structural design of the air guide ring, a duct is formed between the air inlet body and the fan impeller, and the gap between the air guide ring and the fan impeller is blocked by the fence, so that the gap between the air inlet body and the fan impeller is greatly reduced, thereby reducing the leakage of airflow at the air inlet body, improving the performance parameters of the fan, and improving the efficiency of the fan, and the installation of the stainless steel mesh at the air inlet body is more convenient. "

In view of this, we propose a new chemical equipment air inlet adjustment structure. In view of this, a chemical equipment air inlet adjustment structure is provided to overcome the above-mentioned defects. Utility Model Content
