Specific embodiment
Below in conjunction with the accompanying drawings technical scheme is described further, but claimed scope is not limited to institute
State.
A kind of rare-earth smelting hydrochloric acid automatic preparing device as shown in Figure 1, Figure 2, Figure 3 shows, including preparing tank 5, delivery pump
4th, reversal valve a6 and storage tank 1, the discharge end of described preparing tank 5 is connected with the feed end of delivery pump 4, described delivery pump 4
Discharge end is connected with the import of reversal valve a6, the reflux entry end phase of one of outlet of described reversal valve a6 and preparing tank 5
Even, another outlet is connected with the charging aperture of storage tank 1, sets between the discharge end of described delivery pump 4 and the import of reversal valve a6
It is equipped with concentration detector 3, between described reversal valve a6 and storage tank 1, be provided with reversal valve b2, every 2 one group of described storage tank 1
Be connected with two outlets of reversal valve b2 respectively, the import of described reversal valve b2 every 2 one group respectively with another reversal valve b2
Outlet be connected.
Preparing tank 5 is used for preparing the hydrochloric acid of suitable concentration, for the ease of controlling the hydrochloric acid content entering in preparing tank 5, the water yield,
The hydrochloric acid feed end of preparing tank 5 is provided with hydrochloric acid effusion meter 51, the water inlet end of preparing tank 5 is provided with feed water flow gauge 52,
When hydrochloric acid, water enter in preparing tank 5, hydrochloric acid effusion meter 51, water ga(u)ge 52 record to the amount of the hydrochloric acid entering, water,
And signal is fed back to control system, thus the concentration of hydrochloric acid in convenient adjustment preparing tank 5.Hydrochloric acid, water can be to the sides of preparing tank 5
Wall applies certain pressure, for avoiding the pressure that the side wall of preparing tank 5 is applied excessive, the top of preparing tank 5 is provided with liquid
Position detector 11, when the liquid level in preparing tank 5 exceeds Level meter 11, Level meter 11 sends letter to control system
Number, thus stopping to when filling hydrochloric acid or water in preparing tank 5.
For the ease of the hydrochloric acid prepared in preparing tank 5 is transported to each storage tank 1, the discharge end of preparing tank 5 and delivery pump 4
Feed end be connected, by hydrochloric acid apply pressure, thus ensureing that hydrochloric acid can rapidly reach each storage tank 1.
Before hydrochloric acid is transported to each storage tank 1, need the concentration of hydrochloric acid is detected, therefore the going out of delivery pump 4
It is provided with concentration detector 3 between material end and the import of reversal valve a6, by concentration detector 3, concentration of hydrochloric acid is detected,
The hydrochloric acid not meeting concentration requirement needs to carry out to prepare from new adjustment.
Flow back in preparing tank 5 for the ease of undesirable hydrochloric acid and again prepared, delivery pump 4 discharge end with
The import of reversal valve a6 is connected, and one of outlet of reversal valve a6 is connected with the reflux entry end of preparing tank 5, another outlet
It is connected with the charging aperture of storage tank 1, when concentration of hydrochloric acid meets and should store concentration of hydrochloric acid requirement in storage tank 1, hydrochloric acid is directly defeated
Deliver in storage tank 1, when undesirable be, through reversal valve a6, hydrochloric acid is flowed back to preparing tank 5 and adjust concentration.
In the course of the work, the hydrochloric acid that in each storage tank 1, storage finite concentration requires and certain amount of storage requires,
Therefore hydrochloric acid conveying needs to meet the concentration requirement in storage tank 1 and amount of storage requirement, the salt prepared from preparing tank 5 simultaneously
Acid, although controlling inflow and enter hydrochloric acid content, its concentration differs the requirement surely reaching in storage tank 1, meanwhile, reaches dense
Degree also may not necessarily reach amount of storage in storage tank 1 and require when requiring.When can not meet concentration requirement and amount of storage requires simultaneously,
Hydrochloric acid must be back in preparing tank 5, and the hydrochloric acid of backflow can lead to the concentration of hydrochloric acid in preparing tank 5 to change.In order to avoid
Hydrochloric acid, in the preparation repeatedly of preparing tank 5, avoids discharge pressure in course of conveying to change, in reversal valve a6 and storage tank simultaneously
It is provided with reversal valve b2, every 2 one group of storage tank 1 is connected with two outlets of reversal valve b2 respectively, and reversal valve b2 enters between 1
Every 2 one group of mouth is connected with the outlet of another reversal valve b2 respectively, and the hydrochloric acid prepared therefore in preparing tank 5 reaches a certain depositing
When the concentration requirement of storage tank 1 and amount of storage require, hydrochloric acid can be fed rapidly in this storage tank 1.In order to avoid detecting storage tank 1
In amount of storage, the top of storage tank 1 is provided with Level meter 11.
