It is worth noting that, moisturizing, heating stepses are carried out during two incubator differences.That is, when incubator I is carried out When moisturizing or heating, incubator II is just without moisturizing or heating.Ensure that priming steps are not out of stock.

Step 3. stirs.Eddy flow is formed in the inner-outer circulation of agitator tank 1 by urea liquid.Open up and follow in the side wall of agitator tank 1 Ring solution inlet 7 and circulation solution outlet 8, and a water circulating pump 15 is set so that the water inlet end of water circulating pump 15 is molten with circulating Liquid outlet 8 is connected and water side connects with circulation solution entrance 7.Urea in storing basket 9 is dissolved, it is continuous in the inner chamber of agitator tank 1 Stirring, and dissolving is constantly washed away to the urea in storing basket 9.Storing basket 9 can avoid the solid urea of bulky grain from entering In agitator tank 1.

Step 4. discharge opeing.Urea liquid is discharged into agitator tank 1 after urea liquid reaches preset concentration.In water circulating pump 15 Tee ball valve 16 is set between circulation solution entrance 7, and the tee ball valve 16 has two delivery ports, wherein a delivery port is with following Ring solution inlet 7 is connected, and another delivery port connects with the finished product efferent duct 5 for solution to be discharged；When being stirred, cut Disconnected path between tee ball valve 16 and finished product efferent duct 5, solution is allowed to exist by circulation solution entrance 7 and circulation solution outlet 8 Circulated between agitator tank 1 and water circulating pump 15；After solution concentration reaches requirement, cut-out tee ball valve 16 and circulation solution entrance Path between 7, solution is allowed to flow to finished product efferent duct 5.Before the discharge agitator tank 1 of the urea liquid after preset concentration is up to Filtered.A post-filter 17 is preferably added between tee ball valve 16 and finished product efferent duct 5 to be filtered.

It the above is only preferred embodiment of the present utility model, it is noted that above-mentioned preferred embodiment should not regard For that should be defined to limitation of the present utility model, the scope of protection of the utility model by claim limited range.For For those skilled in the art, do not departing from spirit and scope of the present utility model, can also make some Improvements and modifications, these improvements and modifications also should be regarded as the scope of protection of the utility model.
