AI Technical Summary

Technical Problem

Existing potassium magnesium sulfate fertilizer production facilities produce potassium magnesium sulfate fertilizer with uneven crystal water content after the finished product is stacked and dried, which affects production efficiency.

Method used

A device comprising a drying chamber and a mixing drum was designed. The drying chamber is equipped with auxiliary components such as a moving plate, a partition plate, a hydraulic rod, and a motor. Through a layered drying and moisture collection system, the uniform drying of the potassium magnesium sulfate fertilizer product is ensured, and the flotation efficiency is improved by adding a collector through a rotating drum.

Benefits of technology

This method achieves uniform drying of potassium magnesium sulfate fertilizer, avoids the problem of uneven crystal water content, and improves production efficiency and flotation efficiency.

Abstract

The application discloses a kind of drying mixing device for potassium magnesium sulfate fertilizer production, including mixing bucket and drying box, auxiliary assembly is arranged in drying box, auxiliary assembly includes the moving plate that is arranged in one end of drying box, multiple chutes are opened in moving plate, a partition plate is slidably clamped in each chute, a pair of limiting grooves are opened in the bottom end of drying box, a sliding block is slidably clamped in two limiting grooves, the one end of sliding block is connected with slide shaft, sleeve shaft is connected on slide shaft, two sleeve shafts are connected by bidirectional hydraulic rod, and bidirectional hydraulic rod is fixedly arranged on the outside of drying box.Auxiliary assembly can cooperate with drying box to layer drying of potassium magnesium sulfate fertilizer product, to prevent the case that the water content of potassium magnesium sulfate fertilizer product is obviously uneven after drying, drive bidirectional hydraulic rod to elongate, the partition plate arranged in chute will slide along chute, so as to extrude potassium magnesium sulfate fertilizer product between different partition plates, effectively alleviate the case that the water content of potassium magnesium sulfate fertilizer is uneven after drying.
