Description

A lime digestion dosing and feeding device

technical field

The utility model relates to the technical field of water treatment, in particular to a lime digestion, dosing and feeding device.

Background technique

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 tank for neutralization, lime slag falls in the slag hopper, and is transported away by car regularly; or the fine lime in the fine lime tank enters the mixing tank through the first chute to add water Stir to form lime slurry, and then the lime slurry enters the lime slurry sedimentation tank through the second chute for sedimentation. The milk of lime on the upper layer of the sedimentation tank is filtered through a screen and enters the milk of lime tank, and the milk of lime in the milk of lime tank is sent to the neutralization tank for further processing. For neutralization, the lime slag in the lime slurry sedimentation tank is regularly removed by excavators or manually, and transported away by car. The use of refined lime in the first digestion and dosing process leads to high cost and major defects of lime dust, while 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 a trolley, which has uneven feeding, time-sharing feeding, and no continuity, which affects the digestion effect.
