Magnetic pump dosing device

Abstract

The invention discloses a magnetic pump dosing device. The device comprises a magnetic pump and a dosing cylinder, wherein the magnetic pump comprises a pump body, a magnetic conductor and a motor; the magnetic conductor comprises an external magnetic rotor and an internal magnetic rotor; the pump body is positioned in the dosing cylinder; the internal magnetic rotor is connected with the pump body; the external magnetic rotor is coaxially and fixedly connected with the motor; and the internal magnetic rotor is opposite to the external magnetic rotor. The magnetic pump dosing device inputs triethylamine into the working chamber of a cold-box core shooter; the pump body is sealed in the dosing cylinder, so leakage is avoided, the safety of the triethylamine is ensured, the environmental pollution is avoided, and more importantly, the corrosion of the triethylamine to the dosing cylinder and the pump body is small; therefore, the service life of the magnetic pump dosing device is relatively long, and the cost of enterprises can be effectively reduced.

Description

technical field [0001] The invention relates to the field of casting, in particular to a quantitative device for inputting liquid triethylamine into a working chamber of a cold box core shooter. Background technique [0002] In the modern casting production process, in order to improve the casting efficiency and meet the requirements of modern production, most of the cores used in the casting process are manufactured by hot core box core shooters, which are widely used in the foundry machinery industry. The core made by the hot core box core shooter has the advantages of accurate size and smooth surface, so it is widely used in many foundry companies. [0003] In foundry production, the cold box core shooter studio needs to heat the liquid triethylamine into a gaseous state after quantification, and then blow the gaseous triethylamine into the cold box core shooter through the carrier compressed air to complete the amine blowing process. At present, the input of triethylami...

[0003] In foundry production, the cold box core shooter studio needs to heat the liquid triethylamine into a gaseous state after quantification, and then blow the gaseous triethylamine into the cold box core shooter through the carrier compressed air to complete the amine blowing process. Action, at present, the input of triethylamine into the working room of the cold box core shooter is generally quantified by using a thin film, but due to the short service life of the thin film and the high price of spare parts, the production cost is relatively high
