Solution carbon black prepares the method and device of zinc sulfate.
The present invention is achieved by the following measures：
The method that a kind of waste tyre pyrolytic carbon black of the present invention prepares zinc sulfate, includes the following steps：
Step 1, pyrolytic carbon black is crushed to more than 600 mesh, the pyrolytic carbon black particle after crushing is poured into reaction kettle；
Step 2, dilute sulfuric acid is poured into reaction kettle, and is stirred, makes dilute sulfuric acid and the oxidation in pyrolytic carbon black
Adequately chemical reaction generation zinc sulfate occurs for zinc；
Step 3, when the mixture pH value to be checked measured in reaction kettle is neutral, the mixture in reaction kettle was carried out
Filter；
Step 4, the liquid after filtering is dried, finally obtains the crystal of zinc sulfate.
The mixed volume ratio of a concentration of 10%-15% of above-mentioned dilute sulfuric acid, dilute sulfuric acid and pyrolytic carbon black is 1: 2.
A kind of waste tyre pyrolytic carbon black of the present invention prepares the device of zinc sulfate, including reaction kettle, filter press and dries pot,

Bottom portion is answered to be provided with discharge port, feed inlet is provided at the top of the filter press, press filtration motor spindle is provided with liquid outlet, described anti-
The discharge port of kettle is answered to be connected with the feed inlet of filter press by pipeline, liquid outlet and the drying pot of the filter press pass through pipeline
It is connected.
PH value detection device is provided on aforesaid reaction vessel.
Valve is provided on the pipeline that the discharge port of aforesaid reaction vessel is connected with the feed inlet of filter press.
The beneficial effects of the invention are as follows：Waste tyre pyrolytic carbon black can be made full use of to prepare zinc sulfate, turned waste into wealth, than passing
Controlling has saved cost for zinc sulfate, and more environmentally friendly, improves the utilization ratio of pyrolytic carbon black.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Wherein：1 reaction kettle, 2 filter presses, 3 drying pots, 4 driving motors, 5 agitating shafts, 6 pH value detection devices, 7 valves.
Specific embodiment
Further detailed description is done to the present invention below in conjunction with the accompanying drawings：
As shown in Figure 1, the method that a kind of waste tyre pyrolytic carbon black of the present invention prepares zinc sulfate, includes the following steps：
Step 1, pyrolytic carbon black is crushed to more than 600 mesh, the pyrolytic carbon black particle after crushing is poured into reaction kettle 1；Heat
Solution carbon black crushing, which reaches, more than 600 mesh can reach the requirement chemically reacted in next step.Step 2, it is poured into reaction kettle 1
Dilute sulfuric acid, and be stirred, make dilute sulfuric acid that adequately chemical reaction generation sulfuric acid occur with the zinc oxide in pyrolytic carbon black
Zinc.Step 3, when the mixture pH value to be checked measured in reaction kettle 1 is neutral, illustrating dilute sulfuric acid, the reaction was complete, and liquid reaches
Neutrality is arrived.Mixture in reaction kettle 1 is filtered；Step 4, the liquid after filtering is dried, finally obtains sulphur
The crystal of sour zinc.Through overtesting, a concentration of 10%-15% of dilute sulfuric acid, the mixed volume ratio of dilute sulfuric acid and pyrolytic carbon black is 1
: 2, prepare best results.
A kind of waste tyre pyrolytic carbon black of the present invention prepares the device of zinc sulfate, including reaction kettle 1, filter press 2 and drying
Pot 3 is provided with agitating shaft 5 in the reaction kettle 1, and the agitating shaft 5 is connected with driving motor 4, and 1 top of reaction kettle is provided with object
Expect import, 1 bottom of reaction kettle is provided with discharge port, and 2 top of filter press is provided with feed inlet, and 2 bottom of filter press is provided with
Liquid outlet, the discharge port of the reaction kettle 1 are connected with the feed inlet of filter press 2 by pipeline, the liquid outlet of filter press 2 and baking
