Dryer with shredder sharpening device

"Shredder sharpening device and multi-stage rotary dryer with sharpening device" is the patented product (patent number: ZL201310365679.X) declared by ZJN in 2013. This patented technology is specially designed for high-viscosity and high-viscosity Material.

In the previous rotary dryer, there was also breaking shaft device. In the Patent of 201110163259.4, it mentioned the breaking shaft through the whole dryer. The breaking shaft is used to break the wet material in case of caking, thus improving the drying effect. The existing technology is generally based on the function of rotary drum. When it turns, the material will randomly hit the shaft to be broken. With very strong randomness, some cakes may not be touched, the effect of crushing relates to the turning times as well as the the density of rakes. So the effect is not so satisfactory.

This new invention is the improved technology. The shattering device includes a main shaft and two parallel plates installed in the middle of the main shaft; at least three parallel shatter rods are connected between the two plates. The shaving rods are arranged vertically with the plates, each shaver Pole are equipped with a number of rejection blades. The end of the rejection blade connected with the razor pole by Revolute. Rejection blades paralleled with the pan. The blades in adjacent sharpeners are staggered arrangement.

Multiple stage dryer with this technology, consist of drum body and cover. The drum body comprises N-stage cylinder. From inner to outer: the first-stage cylinder, second-stage cylinder, ... to an N-th stage. It is provided with at least one of the above shattering device. The main shaft is in the lower part of the cover, and the amplitude plate and the shaving rods are located at the discharging end of the first-stage cylinder. The location where the shattering device locates is the only way to get through all the materials. So material cakes will fully broken up, thus improving the efficiency and effect of drying.

This invention has been applied to ZJN "Rotary Rake Three-cylinder Multi-loops Dryer" and “Automatic Turning Rake Segmented and Joint Working Dryer". And formed a series of professional dryers regarding to different humidity and viscosity materials. These dryers have been specially for Industrial solid waste such as electroplating, petroleum, paper, leather, chemicals, brewing and other industries. The drying effect is very satisfactory!
