Spray tower capable of preventing observation window from pollution

Abstract

The invention discloses a spray tower capable of preventing an observation window from pollution. The spray tower comprises a spray tower body, the observation window, a horizontal slide rail, a vertical lifting motor, a vertical lifting rod, a horizontal retractable rod, a horizontal retractable motor, an external metal slider, a glass eraser and a swing rod, wherein the observation window is arranged on the wall surface of the spray tower body in a sealed manner, and a lamp is further arranged in the spray tower body; the vertical lifting motor is glidingly arranged on the horizontal slide rail and connected with the external metal slider; the horizontal retractable rod can stretch and retract periodically; the glass eraser is arranged on the inner side wall surface of the observation window and mutually adsorbed with the external metal slider; the top end of the swing rod is hinged with the glass eraser. A spray rod, a spray nozzle angle and a spray effect can be observed conveniently by means of the conventional observation window on the premise that the structure of the conventional spray tower body is not changed and the air tightness of the spray tower is not affected, observation via the observation window is clear, and the observation window is not prone to pollution.

Description

technical field [0001] The invention relates to a powder production equipment, in particular to a spray tower capable of preventing contamination of an observation window. Background technique [0002] During the spraying process of the spray tower, in order to observe whether the spray angle of the nozzle and the spray volume meet the specified requirements, an observation window will be set on the wall of the spray tower body for observation at any time. However, with the existing observation window, when the spray starts, especially after the spray gun and nozzle are replaced, when debugging, the slurry or powder in the spray tower is very easy to spray on the inner wall of the observation window, thereby blurring the line of sight. Since the atmosphere in the spray tower has been set, which is basically high temperature and high pressure, the inner wall of the observation window can only be cleaned when the spray tower stops running. In this way, especially for continuou...

Problems solved by technology

After this setting, the structure is complicated, especially the sliding of the inner window and the driving of the wiper on the inner window, which makes the structure setting complicated and inconvenient to operate

[0008] 3. The setting of the above scraping brush can only avoid the spraying of the slurry to the observation window as much as possible. Once the inner window is blurred by the slurry, it can only be cleaned after the tower is stopped.
