Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a spray granulation device for high-viscosity composite wax. Background Art

[0002] At present, the spray granulation system on the market atomizes liquid materials through a high-speed rotating atomizer and solidifies and granulates them through air cooling. However, some tiny particulate materials will be discharged as waste gas along with the hot air, which not only pollutes the air but also causes waste of materials. In addition, the existing spray granulation systems generally use pure liquid-phase materials, with uneven atomization spraying, unable to reach a particle size less than 500 microns. Moreover, due to the high viscosity of the high-viscosity composite wax, the nozzle is easily blocked and needs to be cleaned frequently, which brings inconvenience to granulation. In addition, the spray granulation system has complex steps, increasing the labor cost and reducing the production efficiency.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses an explosion-proof lamp tube [CN201310477962.1], which includes a spray drying tower, a cyclone separator, a stirrer, a dust collector, and a material conveyor. The gas material outlet of the spray drying tower is connected to the material inlet of the cyclone separator, the gas outlet of the cyclone separator is connected to the gas inlet of the dust collector, the bottoms of the spray drying tower and the cyclone separator are both connected to the stirrer, and the bottom of the stirrer is connected to the material conveyor.

The processing materials are processed and formed after passing through the blending tank assembly 2, the condenser assembly 4, and the granulation spray tower mechanism 6 in sequence.

[0021] Among them, the granulation spray tower mechanism 6 includes a granulation spray tower main body 61.

A blower 64 is provided on the water vapor introduction pipe 63.

[0022] The steam inlet pipe 63 is used to introduce steam. Through steam atomization, by utilizing the characteristic of the high enthalpy value of steam, it absorbs the heat in the air, thereby rapidly reducing the temperature of the high-viscosity composite wax, causing it to drop from 150 °C to below 50 °C in a short time and quickly change from a liquid state to a particulate solid state. Then, it undergoes preliminary dehydration through a vibrating sieve machine and then through a rotary dehydrator to obtain a dry finished product.

[0023] Furthermore, the feeding port at the upper end of the granulation spray tower main body 61 is provided with a number of conical nozzles 65. The aperture on the conical nozzle 65 is less than 0.3 mm, and the spacing between two adjacent holes is 50 - 60 mm.

By screening the particle size of the samples with a standard sieve, the nozzle with an aperture between 0.2 mm - 0.3 mm, which can achieve a qualified rate of 99% for samples smaller than 500 microns, was finally obtained. Considering the subsequent product yield and the cleaning angle of the nozzle, the nozzle with a small hole diameter of 0.3 mm was finally selected.

Finally, the blended materials are guided to the discharge main pipe 3 through the first discharge branch pipe 26 and the second discharge branch pipe 27 for mixing, so as to avoid the premature mixing of materials that cannot be blended.

[0032] Specifically, a wax melting filter 31 is provided on the discharge main pipe 3. The wax melting filter 31 is a cyclone separator. The discharge main pipe 3 is connected to the first blending tank 21 and the second blending tank 22 respectively through a return pipe 32.
