The good chemical agent of pre-coordination is sprayed on the solid state feed stock to have tiled, is realized and is added chemical drugs into solid state feed stock
Agent.Specifically, spray unit 4 includes reservoir, pump, spray tube and multiple spray heads, it is good that pre-coordination is stored in reservoir
Chemical agent, spray tube are sequentially connected reservoir, pump and spray head, and for multiple spray heads along the setting of moving towards of the first supply unit 3, pump will
Chemical agent in reservoir pumps out and passes through spray head and is sprayed on the solid state feed stock to tile on the first supply unit 3.
Storage tank 5；
Specifically, the storage tank 5 is set to the lower section of the outlet of first supply unit 3, mixes and added change
Learn medicament solid state feed stock by the first supply unit 3 deliver into it is canned in storage tank 5, can be obtained heavy metal stablize
Agent.
As a kind of optional embodiment of the invention, as Figure 2-3, in order to aspect efficiently by solid-state original
Material is put into bucket 2, which further includes equal with 2 quantity of bucket be crushed
Mechanism 7 and the second supply unit 6, the outlet of crushing mechanism 7 is set to the top of the entrance of second supply unit 6, described
The outlet of second supply unit 6 is set to the top of the bucket 2.Solid state feed stock is first passed through into the broken of crushing mechanism 7
After processing, then solid state feed stock is transported into bucket 2 by the second supply unit 6 again.Specifically, the crushing mechanism 7
Including feed hopper 71, a pair of of breaker roll 72 is provided in the feed hopper 71, the lower section of the breaker roll 72 is provided with scraper plate 73,
The plane tangent of the working face of the scraper plate 73 and the breaker roll 72.Pass through feed hopper 71, breaker roll 72 and scraper plate 73
Solid state feed stock, can efficiently be crushed by setting.Specifically, in view of number of types of solid state feed stock often compares
Humidity, large viscosity, such as stalk, excrement etc. are unfavorable for the subsequent progress stirred and evenly mixed, the top of second supply unit 6
It is provided with heating unit 8, the heating unit 8 moves towards arrangement along the second supply unit 6.Preferably, heating unit 8 can be
Solid state feed stock on second supply unit 6 is dried by the setting of heating wire, deviates from major part therein by heating wire
Moisture, reduce its viscosity, facilitate storage and subsequent mixing.
As a kind of optional embodiment of the invention, as shown in figure 5, generating biggish particle in order to prevent, guarantee
The uniformity of grain diameter after mixing, the blending unit 1 further include sieve 18 and the second discharge port 17, and the sieve 18 is set
It sets at first discharge port 16, second discharge port 17 is set on the cylinder 11, and is located at first discharging
16 sides far from the feeding inlet 15 of mouth.In production process, if the partial size of solid state feed stock is greater than the aperture of sieve 18,
It can not pass through the sieve 18 and be discharged from the first discharge port 16 for being equipped with the sieve 18, and the excessive particle of partial size continues by spiral
Blade 13 pushes forward, until being discharged from the second discharge port 17, thus the particulate removal that partial size is excessive.
As another aspect of the present invention, a kind of heavy metal-polluted soil stabilizer treatment method is provided, including by lime
It is mixed after a variety of solid state feed stocks drying in stone particle, excrement particles, the agricultural crop straw of chopping and cauline leaf, charcoal
Uniformly；Mixed solid state feed stock is tiled；Deployed chemical agent is sprayed on the solid state feed stock of tiling；It will spray
The solid state feed stock for spilling chemical agent is canned.It in the present invention, is mixed after first drying solid state feed stock, after drying
Solid state feed stock viscosity it is low, stirring resistance is small, and mixing time is short, high-efficient, then again puts down the solid state feed stock after mixing
Paving, and chemical agent is sprayed on the solid state feed stock after tiling, it is easy to operate efficient, it can either guarantee various solid state feed stocks
Efficient mixing, can also guarantee chemical agent efficiently and in uniform incorporation solid state feed stock.
As a kind of optional embodiment of the invention, the stirring means of the solid state feed stock are by solid state feed stock
Layering tiling, latter solid state feed stock are layered on the top of former solid state feed stock；By the multilayer solid state feed stock after tiling
Subregion stirring.By successively stacking various solid state feed stocks, then subregion is stirred, and there is no mixing dead angles, and
Agitating mode is simple, and blending efficiency is high.
As a kind of optional embodiment of the invention, the drying means of the solid state feed stock is by solid state feed stock
It is crushed；Broken solid state feed stock is tiled；Solid state feed stock after tiling is thermally dried.By broken
It is broken to reduce the stirring resistance in mixing stage to reduce viscosity with the dry moisture content that can reduce in solid state feed stock,
Improve blending efficiency.
The present invention is exemplarily described above, it is clear that present invention specific implementation is not subject to the restrictions described above,
As long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out, or not improved this is sent out
Bright conception and technical scheme directly apply to other occasions, within the scope of the present invention.Protection of the invention
Range should be determined by the scope of protection defined in the claims.
