Powder-liquid anti-blocking mixer for medicine addition

Abstract

The invention discloses a powder-liquid anti-blocking mixer for medicine addition, and aims at providing a powder-liquid anti-blocking mixer which is simple in structure, high in efficiency, good in energy conservation and convenient to repair. According to the technical scheme, a mixing pipeline consists of a side cylinder and a central tube; an anti-blocking flushing device is mounted at the top of the central tube; the anti-blocking flushing device comprises a mounting flange and an ejection tube; the mounting flange is fixed at the upper end of the central tube; a plurality of water inlets are formed in the ejection tube; a flushing nozzle is mounted at the lower end of the ejection tube; the flushing nozzle is mounted below a flushing water inlet pipeline; the central tube is connected with a washing electromagnetic valve through the flushing water inlet pipeline; a powder inlet pipeline is connected with the central tube; the side cylinder is opened downwards and sleeves the central tube; the side cylinder is connected with the water inlet pipeline; an annular water distribution disc is mounted in an annular gap between the side cylinder and the water outlet end of the central tube. The powder-liquid anti-blocking mixer has the advantages that uniform pre-mixing and medicine dust suppression are effectively achieved, and meanwhile the mixer can be automatically powered on to flush the inner wall of the central medicine feeding pipeline with large water flow from fan-shaped nozzles.

Description

technical field [0001] The invention relates to an automatic dosing powder-liquid mixing device used in sewage system treatment. Background technique [0002] The coal preparation plant chooses the X-ZJ automatic dosing system to realize the treatment of mine water and domestic sewage system. The automatic dosing system includes a mixing tank, a storage tank, a feeder, a heating funnel, an air transmission system, and a mixing device Wait. When the system is working, the dry pharmaceutical powder is manually added to the hopper of the solid feeder, brought into the drying funnel by the stainless steel screw at the bottom for heating, and the powder medicament is transferred from the pipeline at the lower end to the drying funnel by the air ring vacuum pump (negative pressure air flow). After mixing with water in the central pipeline, it enters the mixing tank. After the electric agitator works for a certain period of time, the electric gate opens, and the prepared flocc...

Problems solved by technology

In actual work, because the powdered medicine blown by the wind will immediately become a viscous powder-liquid mixture when it encounters water, the central pipeline for transporting the medicine is easily blocked by this viscous powder-liquid mixture, so that the medicine It will not be able to enter the mixing tank normally, and it is necessary to manually clean up the medicine in the central tube to make the dosing system work normally, which is very troublesome
