Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of chemical equipment technical field, especially a kind of high-efficiency drying device for magnesium sulfate heptahydrate. BACKGROUND

[0002] Magnesium sulfate heptahydrate is also known as Epsom salt, sulfur bitter, bitter salt, and is a common chemical substance, and is a colorless or white orthorhombic needle or obelisk crystalline body, and its molecular formula contains seven crystal water. Because of the production process of magnesium sulfate heptahydrate, magnesium sulfate heptahydrate will have a lot of moisture. In order to get better results and more accurate data in experiments and scientific research, we need to reduce the water content of magnesium sulfate heptahydrate.

[0003] However, when using a fluidized bed to dry magnesium sulfate heptahydrate, dry and moist magnesium sulfate heptahydrate particles are mixed together. As a result, during the drying process, due to the flow and friction of the two types of particles, clumping will occur. When magnesium sulfate heptahydrate clumps, it will seriously affect the drying effect, causing the drying time to be extended and uneven drying.

[0004] In order to solve the above technical problems, we need to design a magnesium sulfate heptahydrate drying device that prevents clumping. INVENTION CONTENTS

[0011] Optionally, in order to guarantee the filtering effect of the filter plate, the material of the filter plate is set to be silica gel, so as to realize stronger adsorption effect.

[0012] Compared with the prior art, the utility model has the advantages that when the fluidized bed is used to dry heptahydrated magnesium sulfate, because the heptahydrated magnesium sulfate is humid, and after the fluidized bed works, the fluidized bed mixes the dry heptahydrated magnesium sulfate with the humid heptahydrated magnesium sulfate, which causes the caking of heptahydrated magnesium sulfate particles, and when the heptahydrated magnesium sulfate is caked, the drying efficiency is reduced, the drying time is prolonged, the energy consumption is seriously increased, and the caked heptahydrated magnesium sulfate causes the uneven heating of the material, in order to solve the above problems, first, the hollow stirring rod is used to add the appropriate amount of anti-caking agent into the upper frame, and the three stirring rods are rotated to mix the anti-caking agent with the heptahydrated magnesium sulfate in the upper frame uniformly, so as to ensure the increase of the drying speed and efficiency of the heptahydrated magnesium sulfate.

[0017] In order to better filter the moisture, we will filter plate material set to silica gel, because silica gel is a kind of high activity adsorption material, has excellent moisture absorption performance. BRIEF DESCRIPTION OF DRAWINGS
