Description

Technical Field

[0001] The utility model belongs to the technical field of metering pumps, and particularly relates to an anti-blocking metering pump device. Background Art

[0002] A metering pump is also called a quantitative pump or a proportional pump. A metering pump is a special volumetric pump that can meet the needs of various strict process flows. The flow rate can be adjusted steplessly within the range of 0-100%. It is used to transport liquids. A metering pump is a type of fluid conveying machinery. Its outstanding feature is that it can maintain a constant flow rate that is independent of the discharge pressure. The use of a metering pump can simultaneously complete the functions of conveying, metering and regulation, thereby simplifying the production process. Using multiple metering pumps, several media can be input into the process flow in accurate proportions for mixing. Due to its own prominence, metering pumps have now been widely used in various industrial fields such as petrochemicals, pharmaceuticals, and food.

[0003] A Chinese patent with publication number "CN217206917U" discloses an anti-clogging metering pump for sewage treatment, including a positioning plate, a driving motor is arranged on one side of the upper end surface of the positioning plate, the output end of the driving motor is connected to a gearbox, a pump body casing is arranged on the side of the gearbox, a water inlet is arranged on the side of the pump body casing, a water outlet is arranged on the top of the pump body casing, a negative pressure fan disc is arranged inside the pump body casing, and a transmission shaft is arranged between the gearbox and the negative pressure fan disc.

A large amount of impurities will be sucked into the metering pump at the same time, which will cause the inside of the metering pump to be blocked, and the metering pump will still be blocked. It is also inconvenient for users to clean the impurities inside the metering pump. Utility Model Content
