Description

Discharge port anti-blocking device for spray drying tower

Technical Field

The utility model relates to a spray drying tower field especially relates to a discharge gate prevents stifled device for spray drying tower.

Background

Spray drying is a method for applying systematic technology to material drying. After the thin material is atomized in the drying chamber, the water content is quickly vaporized in the contact of the thin material and hot air, and then the dried product is obtained. The method can directly dry the solution or emulsion into powder or granular product, and can omit the procedures of evaporation, pulverization, etc.

The existing spray drying technology is widely applied to various industries, and a common problem still exists at present is that the drying tower is stuck to the wall, and the wall sticking phenomenon is more serious especially for high-viscosity materials. Many manufacturers have set up the rapping hammer on the drying tower for alleviating the drying tower and glue the wall condition, but the rapping hammer effect is limited, can not clear away the drying tower sizing completely, along with the extension of continuous production time, the sizing of drying tower inner wall is just more, when the sizing accumulates to certain thickness, can take place the slabbing under the jarring effect of rapping hammer, the discharge gate of drying tower is less than the tower body, so the cubic caking material that peels off can be long-pending stifled at the discharge gate to hinder production line equipment normal production.

Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1 to 4, a discharge port anti-blocking device for a spray drying tower comprises a drying tower 1, a feeding pipe 16 arranged at the bottom of the drying tower 1, and a casing 2 fixedly installed between the drying tower 1 and the feeding pipe 16 through a flange;

2 inside wall top of casing is the even interval of circumference and is provided with a plurality of backing sheets 3, just it is provided with the shredding subassembly 4 that is used for carrying out the comminution to 3 upper large materials of backing sheet to lie in backing sheet position departments of backing sheet to be located in casing 2, shredding subassembly 4 includes that horizontal rotation installs the pivot 5 that lies in 3 lower position departments of backing sheet in casing 2, it is provided with a plurality of groups shredding fin 6 to follow its length direction even interval in

pivot

5, 5 one end transmissions in pivot are connected with shredding motor 7, shredding motor 7 fixed mounting is at 2 lateral walls of casing.

And rotating bearings 8 are arranged at two ends of the rotating shaft 5, and the rotating bearings 8 are fixedly arranged on the outer side wall of the machine shell 2 through bearing seats 9. The rotating shaft 5 is installed through the rotating bearing 8, so that the smoothness of the rotating process of the rotating shaft 5 is improved, and the possibility of jamming of the rotating shaft 5 is reduced.

An elastic sealing ring 10 is arranged between the bearing seat 9 and the casing 2, and the elastic sealing ring 10 is sleeved on the rotating shaft 5. Due to the arrangement of the elastic sealing ring 10, the sealing performance of the shell 2 after the rotating shaft 5 is installed is improved, and powder is prevented from leaking through a gap between the rotating shaft 5 and the shell 2.
