I. Overview of Trisodium Phosphate Dryer Equipment

 The three-sodium phosphate sputum dryer discharge gas distribution device comprises a sputum dryer, a suction tank and a vacuum pump, and the discharge port of the sputum dryer is connected with the feed port of the suction tank through a feed pipe, the vacuum pump and The suction tank is connected, characterized in that: a gas distribution device is connected to the feed pipe; the gas distribution device is composed of an air flow passage, a plug and an elastic support, one end of the elastic support is fixed in the passage, and the other end is connected with the plug, so that The plug is suspended in the air flow passage; in the air flow passage, a neck having a diameter smaller than the diameter of the plug is further disposed along the air flow direction. The trisodium phosphate sputum drying structure is simple and the layout is reasonable, which can well solve the clogging problem in the dry powder discharging process.

 Trisodium phosphate The drying method of the sputum drying equipment is: connecting the sputum dryer and the suction tank with a feed pipe, and vacuuming the suction tank with a vacuum pump to take the material from the sputum dryer Transfer to the suction tank. However, since the material is dry powder, it is particularly easy to block the feed pipe between the kneading dryer and the suction tank, so this method often has a clogging failure during use. In order to solve the problem of material clogging, water is added to the rake dryer to form a slurry, and the solid-liquid mixture is input into the suction tank together by a pump.

A gas distribution device is also connected to the feed pipe of the trisodium phosphate drying machine, so that the material and the gas satisfy a certain gas-solid ratio; the gas distribution device is composed of an air flow passage, a plug and an elastic support, and one end of the elastic support is fixed in the passage. The other end is connected to the plug to suspend the plug in the air flow passage; in the air flow passage, a neck having a diameter smaller than the diameter of the plug is further disposed along the air flow direction. When the plugging occurs in the conveying pipe, the airflow intensity in the gas distribution device becomes large, and the plug moves to the neck of the airflow passage under the action of the airflow to seal the passage, so that the material in the conveying pipe is unblocked under the pressure.
