Polyaluminum chloride water purifying agent drying device

Abstract

The invention discloses a polyaluminum chloride water purifying agent drying device which comprises a drying device box, a suction pump and a drying roller, wherein a door is arranged on a front end face of the drying device box, a glass window is arranged at the lower end of the door and on the drying device box, a circulating pipe is arranged on the suction pump, the drying roller is arranged inthe drying device box, an air inlet cavity is fixed in the drying roller, an air guiding cavity is arranged between the outer side of the air inlet cavity and the inner side of the drying roller, a rotating shaft is fixed to the right side of the drying roller, the right end of the rotating shaft is fixed to an output shaft of the motor, an air inlet pipe is arranged in the rotating shaft, an annular array distributed air outlet cavity is arranged at the periphery of the air inlet pipe and in the rotating shaft, the right side of the air inlet pipe is communicated into an air guiding box, theupper end of the air guiding box is connected with a heating device through a first connection pipe, and the upper end of the heating device is connected with an air blower through a second connection pipe. According to the polyaluminum chloride water purifying agent drying device disclosed by the invention, a polyaluminum chloride solution is evenly heated and dried, so that the situation that polyaluminum chloride analytical product quality is reduced due to partial excessive heating is avoided.

Description

technical field [0001] The invention relates to a drying device for water purifying agent, in particular to a drying device for polyaluminum chloride water purifying agent. Background technique [0002] Water purifiers are chemicals that can react with other impurities in water when put into water. Mainly for the purpose of water purification. Commonly used water purifiers include polyaluminum chloride, polyaluminum ferric chloride, basic aluminum chloride, polyacrylamide, ferrous sulfate, aluminum sulfate, polyferric sulfate, etc. At the same time, it has good water purification effect, fast water purification speed, weak acidic pH, inorganic, high safety, no secondary pollution, and is a green environmental protection product. Using natural materials with adsorption capacity as raw materials, it has a strong purification effect and can remove heavy metals in water. The treated raw water is not affected by water temperature and pH value, and has a wide range of applicati...

AI Technical Summary

Problems solved by technology

[0004] At present, in the production process of polyaluminum chloride, the drying method is generally spray drying. During the spray drying process, the temperature is high, and the drying is not uniform enough, and polyaluminum chloride is easy to partially decompose, resulting in low yield and quality.
