[0002] Phthalic anhydride is an organic compound with the molecular formula C8H4O3. It is a cyclic anhydride formed by dehydration of phthalic acid molecules. Phthalic anhydride is a white solid and an important raw material in the chemical industry, especially used in the manufacture of plasticizers. This product is irritating to the eyes, nose, throat and skin. This irritation can be aggravated by its hydrolysis into phthalic acid on the moist tissue surface, which can cause skin burns. Inhalation of this product's dust or vapor can cause coughing, sneezing and epistaxis. For people with a history of asthma, it can induce asthma and other problems. In chemical operations, conveying equipment is needed to safely transport it and participate in the preparation of various chemical products. Existing conveying equipment is mostly a single conveyor belt mechanism with no isolation structure on the outside, directly exposed to the outside, prone to dust emission problems, and unable to maintain a constant temperature during the conveying and loading process, resulting in changes in the characteristics of the raw materials, affecting the quality of the prepared products, and posing certain safety hazards.
