Embodiment example 1

[0017] A method for preventing sodium thiocyanate agglomeration, comprising the following steps: (1) Open the mixing cooler 1, feed the cooling water inlet 4 into 12°C circulating cooling water, start the stirring motor 5, and confirm that the mixing cooling machine 1 is operating normally ; (2) Open the feed port 8 and put in the dried product, at this time the product temperature is 60°C; (3) When the feed amount reaches 1 / 3 of the volume of the mixing cooler 1, add anti-caking through the feed port 7 (4) Continue to add the product, when the product accounts for 3 / 4 of the volume of the mixing and cooling machine 1, stop feeding; (5) Stir the product and the anti-caking agent through the stirring impeller 6 and then mix the product and the anti-caking agent in the mixing and cooling machine 1 Internally cool to normal temperature, open the discharge port 3 to discharge the material, and obtain the anti-caking product; (6) Cooling water outlet 2 releases cooling water, and tu...

Embodiment example 2

[0020] A method for preventing sodium thiocyanate from agglomerating, comprising the following steps: (1) Open the mixing cooler 1, feed the cooling water inlet 4 into 15°C circulating cooling water, start the stirring motor 5, and confirm that the mixing cooling machine 1 is operating normally ; (2) Open the feed port 8 and put in the dried product, at this time the product temperature is 70°C; (3) When the feed amount reaches 1 / 3 of the volume of the mixing cooler 1, add anti-caking through the feed port 7 (4) Continue to add the product, when the product accounts for 3 / 4 of the volume of the mixing and cooling machine 1, stop feeding; (5) Stir the product and the anti-caking agent through the stirring impeller 6 and then mix the product and the anti-caking agent in the mixing and cooling machine 1 Internally cool to normal temperature, open the discharge port 3 to discharge the material, and obtain the anti-caking product; (6) Cooling water outlet 2 releases cooling water, a...

Embodiment example 3

[0023] A method for preventing the formation of sodium thiocyanate, comprising the following steps: (1) Open the mixing cooler 1, feed the cooling water inlet 4 into 17°C circulating cooling water, start the stirring motor 5, and confirm that the mixing cooling machine 1 is operating normally ; (2) Open the feed port 8 and put in the dried product, at this time the product temperature is 75°C; (3) When the feed amount reaches 1 / 3 of the volume of the mixing cooler 1, add anti-caking through the feed port 7 (4) Continue to add the product, when the product accounts for 3 / 4 of the volume of the mixing and cooling machine 1, stop feeding; (5) Stir the product and the anti-caking agent through the stirring impeller 6 and then mix the product and the anti-caking agent in the mixing and cooling machine 1 Internally cool to normal temperature, open the discharge port 3 to discharge the material, and obtain the anti-caking product; (6) Cooling water outlet 2 releases cooling water, and...

Abstract

The invention discloses a method of preventing sodium thiocyanate from caking. The method comprises the following steps: (1), confirming that operation of a mixing cooler is normal; (2), opening a feeding hole, placing a dried product, wherein the temperature of the product is 60 DEG C-75 DEG C; (3), adding an anti-caking agent through the feeding hole when feeding amount is 1 / 3 capacity of the mixing cooler; (4), further adding the product, and stopping feeding when the product reaches 3 / 4 capacity of the cooling mixer; (5), cooling to the normal temperature in the mixing cooler after mixing completely, and opening a discharging hole for discharging; (6), discharging cooling water from a cooling water outlet and switching off a stirring motor. A device used in the invention adopts a design of dividing wall cooling and multi-layer impeller stirring to ensure that the product temperature can be quickly lowered, so that caking possibility after product packaging is lowered; moreover, the product and the anti-caking agent are uniformly mixed, so that the anti-caking effect is ensured radically.

Description

technical field [0001] The present invention is specifically a method for preventing sodium thiocyanate from agglomerating. Background technique [0002] A very troublesome characteristic of sodium thiocyanate products is agglomeration, that is, lumps are formed by mutual extrusion in a loose state, especially in hot and humid seasons, long-term stacking, and stacking extrusion, which brings serious problems to the use of the product. Great inconvenience. At present, the main measures to prevent the caking of sodium thiocyanate products are strict drying operation to reduce the moisture content of the product; reduce the product temperature during packaging; pack in an environment with very low humidity and store in airtight packaging; reduce the stacking pressure during storage. However, after the above anti-caking measures are satisfied, caking still cannot be completely prevented. Contents of the invention [0003] The technical problem solved by the present invention...
