AI Technical Summary

⚠Technical Problem

Traditional wastewater treatment dosing equipment suffers from insufficient control precision in the design of the chemical delivery system. It cannot adjust the dosing rate in real time according to changes in water quality, resulting in waste or insufficient chemicals, affecting treatment effect and system stability. Furthermore, the structural stability of improved equipment is insufficient, leading to drift and unpredictable changes in the chemical delivery velocity.

⚗Method used

The equipment employs a speed regulating device and a locking mechanism. The speed regulating device achieves precise adjustment of the liquid flow rate through components such as a speed regulating sleeve, a matching rod, and a speed regulating block. The locking mechanism constructs an anti-vibration protection system through components such as a control sleeve, a screw sleeve, and a displacement block, ensuring stable operation of the equipment under high pressure and vibration environments.

🎯Benefits of technology

It achieves precise and adjustable chemical delivery, improves the efficiency of chemical use, reduces treatment costs, avoids problems such as insufficient flocculation, poor sedimentation, and inhibition of the biological system, ensures the stability of effluent quality and system operation, and reduces operating costs and compliance risks.

Abstract

This utility model discloses a wastewater treatment dosing device, including a delivery pump. One end of the delivery pump is connected to a speed regulating device, which includes a delivery pipe, a speed regulating sleeve, a matching rod, a matching sleeve, a connecting sleeve, a thrust bearing, a movable sleeve, a speed regulating block, a speed regulating plate, and a speed regulating groove. The matching rod is located inside the speed regulating sleeve, and the matching sleeve is located in the movable sleeve. The connecting sleeve and the movable sleeve are installed on both sides of the thrust bearing. The outer wall of the movable sleeve is threaded to the inner wall of the delivery pipe. The speed regulating block is installed on one side of the speed regulating plate. The speed regulating groove is inclinedly opened inside the delivery pipe. A locking mechanism is provided on the outside of the delivery pipe. The locking mechanism includes a control sleeve, a screw sleeve, a driving wheel, a screw, a driven wheel, a shift block, a fixed block, a shift spring, and a shift sleeve. The screw sleeve is sleeved on the outside of the screw and installed on one side of the driven wheel. The driving wheel is installed on one side of the control sleeve. The shift spring is connected to two adjacent shift blocks. This utility model solves the defects of low drug delivery accuracy and poor stability of the regulating system.
