The utility model aims at providing an easily clear up spray drying tower who glues wall material.
The utility model has the innovation point that when the spray drying tower works, the airflow sprayed by the blowing device can form a layer of air film protection through the rectification of the annular diversion bin; when the spray drying tower is cleaned, the blowing device moves up and down to blow and sweep the materials adhered to the inner wall of the tower body.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that:
a spray drying tower easy to clean wall-sticking materials comprises a tower body, wherein the tower body is of a cylindrical structure, an atomizing disc is arranged at the center of the tower body, a discharge hopper is arranged at the bottom of the tower body, an air inlet pipe is introduced into the tower body, and an air outlet pipe is arranged at the lower part of the tower body; the tower body is internally provided with an annular diversion bin, when the blowing device is positioned at the upper part of the tower body, the annular diversion bin is positioned at the outer ring of the blowing device, a circle of air inlets corresponding to the air nozzles are arranged on the inner ring of the annular diversion bin, and a circle of vertically downward air blowing openings are arranged at the bottom of the annular diversion bin.
When the spray drying tower works, the air flow sprayed by the blowing device can form one layer of air film protection through rectification of the annular diversion bin, due to the protection of the air film, the material amount of the adhesion on the inner wall of the tower body is reduced, when the spray drying tower needs to be cleaned, the driving assembly pushes the blowing device to move up and down, the high-pressure air flow sprayed by the air nozzle cleans the inner wall of the tower body, and when the material amount of the adhesion on the inner wall of the tower body is reduced, the inner wall of the tower body can be automatically cleaned, and the cleaning effect is good.
Preferably, the air nozzles are uniformly distributed in the circumferential direction of the air ring; a plurality of clapboards which are arranged along the circumferential direction of the annular diversion storehouse are arranged in the annular diversion storehouse. The air nozzles are uniformly distributed, the air outlet amount of each circumferential part of the blowing ring is consistent, the partition plate is more favorable for shunting air sprayed by the air nozzles, turbulent flow is not easy to occur, and the kinetic energy of the stable air flow of the air outlets of the annular diversion chamber is increased.
Preferably, the driving assembly comprises a cylinder arranged at the top of the tower body, and a piston rod of the cylinder penetrates through the tower body and is connected with the purging device. The piston rod of cylinder promotes to sweep the ring and reciprocates, simple structure, easy maintenance.
Preferably, the piston rod of the air cylinder and the guide rod are both sleeved with corrugated pipes. Avoid the interior material adhesion of tower body at piston rod and guide bar, cause to sweep the ring and move from top to bottom and block.
The utility model has the advantages that:
1. when the spray drying tower works, the air flow sprayed out by the blowing ring can form a layer of air film protection through the rectification of the annular diversion bin; when the spray drying tower is cleaned, the blowing ring moves up and down to blow and sweep the materials adhered to the inner wall of the tower body.
2. The utility model discloses in add the baffle and more be favorable to the gas reposition of redundant personnel with air cock spun, be difficult for appearing the turbulent flow.
3. The utility model discloses in add bellows and avoid the interior material adhesion of tower body at piston rod and guide bar, cause to sweep and move the card pause from top to bottom of ring.
