Description

Technical Field

[0001] The utility model relates to the technical field of metering devices, in particular to a phosphorus oxychloride metering device. Background Art

[0002] In order to make the chemical production raw materials undergo quantitative chemical reactions in the reactor, control the reaction speed of the raw materials in the reactor, and prevent the production of more by-products, it is usually necessary to control the addition speed and amount of the production raw materials. As a commonly used equipment in chemical production, the metering tank can accurately measure the addition amount of production raw materials or catalysts and control the addition speed of raw materials or catalysts. Among the current phosphorus-based flame retardants, the production process of bisphenol A diphenyl phosphate (BDP) is mainly as follows: solid raw materials bisphenol A and catalysts are fed into the reactor through a feeder, and the liquid phosphorus oxychloride flows through a metering device for metering and then transferred to the reactor, and an esterification reaction is carried out after it is fully dissolved.

[0003] However, the metering box in the existing metering device generally adopts a single-layer structure, which has low structural strength and poor collision resistance. When a moving object unexpectedly hits the metering device, the impact force generated can easily cause damage to the metering device.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
