Description

Ammonium removing equipment and method for potassium nitrate Technical Field The application relates to the field of ammonium removal equipment, in particular to ammonium removal equipment and an ammonium removal method for potassium nitrate. Background In the field of chemical production, the removal of ammonium from potassium nitrate is an important process link, and the purpose of the removal of ammonium chloride mixed in potassium nitrate is to improve the purity of the product. Existing ammonium removal equipment typically includes a fixed dissolution tank for holding water, soda ash, and potassium nitrate mixed with ammonium chloride. However, the static dissolution mode has the problem of insufficient mixing degree, so that the reaction time of sodium carbonate and ammonium chloride is long, and the ammonium removal efficiency is low. In order to improve the mixing degree, some devices attempt to introduce a stirring device, and the existence of the stirring device sometimes cannot avoid precipitation phenomenon, so that the reaction degree is reduced, and therefore, the problem of how to improve the reaction degree is needed to be solved. Disclosure of Invention In order to improve the reaction degree, the application provides an ammonium removal device and an ammonium removal method for potassium nitrate. In a first aspect, the application provides an ammonium removal device for potassium nitrate, which adopts the following technical scheme: an ammonium removal apparatus for potassium nitrate comprising: A frame; The dissolving cylinder is rotationally connected to the frame around the axis of the dissolving cylinder, and the rotation axis is parallel to the first direction; a motor connected between the frame and the dissolving cylinder for driving the dissolving cylinder to rotate along the frame, and The stirring assembly comprises a plurality of stirring blades fixedly connected to the inner wall of the dissolving cylinder, and the stirring blades are distributed at intervals on the rotation circumference of the dissolving cylinder. According to the technical scheme, when the dissolving barrel is used, the axis of the dissolving barrel is in the horizontal direction, the first exhaust hole is positioned at the position close to the dissolving barrel, water, potassium nitrate mixed with ammonium chloride and sodium carbonate are added into the dissolving barrel through the first exhaust hole, then the motor drives the dissolving barrel to rotate positively and reversely by a certain angle to shake materials in the dissolving barrel, so that the mixing degree of the materials in the dissolving barrel is improved, the ammonium chloride mixed in the potassium nitrate and the sodium carbonate react more fully, in addition, as the stirring blades are fixedly connected in the dissolving barrel, the stirring blades are prevented from precipitating along with the shaking of the dissolving barrel, the full degree of the reaction of the ammonium chloride mixed in the potassium nitrate and the sodium carbonate can be improved, and after the reaction is finished, the liquid in the dissolving barrel can be pumped out from the first exhaust hole. Optionally, an air exhaust ring groove for separating the dissolving barrel into a plurality of dissolving sections in a first direction is formed in the dissolving barrel, the air exhaust ring groove penetrates through the barrel wall of the dissolving barrel in a direction perpendicular to the axis of the dissolving barrel, and a connecting rod is fixedly connected between two adjacent dissolving sections; A fixed ring is fixedly connected to the frame, the fixed ring is sleeved between the two sections of dissolution sections, the end parts of the dissolution sections are rotatably connected to the fixed ring so as to seal the exhaust ring grooves, and the first exhaust holes are formed in the fixed ring; when the axis of the dissolving cylinder is horizontal, the first exhaust hole is positioned at the top of the fixed ring. Through adopting above-mentioned technical scheme, because first exhaust hole is in the top of solid fixed ring, and because gu fixed ring is fixed in the frame, therefore, the dissolving cylinder can rotate bigger range, also can reduce the liquid in the dissolving cylinder and splash outside the dissolving cylinder from first exhaust hole. Optionally, a discharging hole is formed in the barrel wall of the dissolving barrel, and a second sealing plug is connected to the dissolving barrel and used for sealing the discharging hole. Through adopting above-mentioned technical scheme, through setting up the bin outlet, can be convenient for discharge the liquid in the dissolving cylinder, when need not flowing back, only need to seal the stopper with the bin outlet shutoff can. Optionally, the dissolving device further comprises an exhaust assembly, wherein the exhaust assembly comprises two first exhaust pipes, and the first exhaust pipes are fi
