Lime slaking and chemical feeding device

Abstract

The invention discloses a lime slaking and medical feeding device which comprises a lime transporting unit, a lime slaking unit, a lime milk separating unit and a lime chemical feeding unit. The lime slaking unit comprises a barrel body, a feed hole and a discharge hole are formed in the barrel body, and the interior of the barrel body is sequentially divided into a buffer area, a homogeneity area, a milk-residue separation area, a residue salvaging area and a residue discharging area from the feed hole to the discharge hole; unslaked lime is slaked into lime milk and sand water mixtures through the lime slaking unit, and the lime milk and sand water mixtures flow out from the discharge hole; the lime milk and sand water mixtures flowing in the lime milk separating unit from the discharge hole are separated to lime milk and lime residues by the lime milk separating unit; the lime feeding device can push lime and is installed under a fine lime tank, and a lime outlet of the lime feeding device is located over a feed hole of the lime slaking unit. By adopting the feeding device, automatic feeding can be performed, the working efficiency is improved, and labor force is saved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a lime digestion dosing and feeding device. Background technique [0002] The existing lime digestion and dosing process generally adopts the following two methods: one is to hoist the refined lime from the warehouse to the lime milk preparation tank to make a lime milk solution with a concentration of 20%, and then use the pump to send the lime milk to the sewage acid , one-stage, two-stage, three-stage neutralization tank for neutralization. The second is to send the refined lime in the refined lime tank to the lime tank, where the refined lime is soaked in contact with water, and after a period of natural cooling, it is grabbed by a grab bucket to the intermediate warehouse, then washed with water and entered into the lime digester, and finally discharged through the slag discharge screw. Separation of lime slag and lime milk, lime milk is sent to the neutralization t...

AI Technical Summary

Problems solved by technology

Adopting the first digestion and dosing process uses refined lime, which leads to high cost and major defects of lime dust, and the second digestion and dosing process has the disadvantages of serious waste of lime, frequent equipment blockage, and high failure rate.

The existing lime dosing and feeding is done by hoisting or manually pushing the trolley, which has uneven feeding, time-sharing feeding, no continuity, and affects the digestion effect
