Description

Technical Field

[0001] The utility model relates to the technical field of calcium hydrogen phosphate preparation, and more specifically to an extraction device for calcium hydrogen phosphate production. Background Art

[0002] Calcium hydrogen phosphate, also known as dicalcium phosphate, is a white crystal or crystalline powder. It is usually prepared by the water extraction method. It uses agricultural common superphosphate as raw material and is obtained by multi-stage water extraction, defluorination, and lime milk neutralization. The soluble phosphorus pentoxide in superphosphate is extracted from the solid phase by multi-stage extraction with water (solid-liquid ratio of 1.0-4.1). Sodium chloride or activated silica is added for defluorination purification during extraction. Then, plate and frame filter press is used to remove phosphogypsum residue. The filtrate is neutralized with lime milk containing 6%-8% of CaO. After the neutralized liquid is allowed to stand, it is filtered and dried to obtain the finished product. However, the current extraction devices all place the raw materials and the extractant directly in the extraction chamber, and through artificial stirring, they react naturally in and out of the extraction. Not only is the reaction speed slow, but it is also impossible to maintain the optimal reaction temperature of superphosphate extraction, defluorination purification and other processes, thereby reducing the reaction speed and production efficiency of calcium hydrogen phosphate. Utility Model Content

[0004] The utility model provides the following technical solutions: an extraction device for producing calcium hydrogen phosphate, comprising an extraction box, a heating and heat preservation box is arranged on the outer side of the extraction box, a heating tube located on the inner wall of the extraction box is arranged inside the heating and heat preservation box, a steering device is arranged on the top of the extraction box, a driving motor is arranged on the top of the steering device, a transmission shaft located inside the extraction box is arranged on the bottom of the steering device, a stirring blade is arranged on the outer side of the transmission shaft, water inside the heating and heat preservation box is heated, so that hot water passes through the extraction box through the heating tube, thereby cooperating with the heating and heat preservation box to heat the inside and outside of the extraction box at the same time, so that the optimal reaction temperature of superphosphate and the subsequent extraction and defluorination purification temperature are maintained, and at the same time, the driving motor drives the steering device to drive the transmission shaft and the stirring blades on its outer side to rotate and stir in the extraction box, so that the reaction is more uniform and thorough, thereby improving the production efficiency of calcium hydrogen phosphate;

[0005] Furthermore, stirring holes are evenly opened on the surface of the stirring blade, and the contact area between the stirring blade and the solution in the extraction box is increased through the stirring holes, thereby increasing the stirring range of the stirring blade and making the stirring more uniform.

[0006] Furthermore, there are four stirring blades, and the four stirring blades are located on the upper and lower sides of the heating tube. The heating tube, the transmission shaft, and the stirring blades all form an angle of 15 degrees with the horizontal plane. The four stirring blades stir the extraction box at the same time, and the angle of 15 degrees with the horizontal plane increases the stirring area of ​​the stirring blades, thereby making the solution in the extraction box flow up and down, thereby increasing the reaction area.

[0007] Furthermore, a bottom plate is provided at the bottom of the inner wall of the extraction box, and a supporting cylinder is provided at the top of the bottom plate. The supporting cylinder is circular, and the top of the bottom plate forms an angle of 15 degrees with the horizontal plane. It is movably connected to the transmission shaft through the supporting cylinder, so that it is convenient for the staff to disassemble and remove the transmission shaft and stirring blades from the extraction box, and it is convenient for the staff to disinfect and clean the extraction box and the stirring blades and stirring holes separately, thereby increasing the cleanliness of the interior of the extraction box, the transmission shaft, and the stirring blades and the comfort of use for the staff.

[0008] Furthermore, a support column is provided at the bottom of the heating and insulation box, a discharge port located inside the heating and insulation box is provided on the outside of the extraction box, and a feed port located on one side of the steering device is provided on the top of the extraction box. The device is supported by the support column, reaction raw materials are added to the extraction box through the feed port, and the reaction products are discharged and collected through the discharge port.

[0009] Compared with the prior art, the beneficial effect of the present invention is that the water inside the heating insulation box is heated by the heating insulation box, so that the hot water passes through the extraction box through the heating pipe, thereby cooperating with the heating insulation box to heat the inside and outside of the extraction box at the same time, so that the optimal reaction temperature of superphosphate and the subsequent extraction and defluorination purification temperature are maintained. At the same time, the driving motor drives the steering device to drive the transmission shaft and the stirring blades on its outer side to rotate and stir in the extraction box, so that the reaction is more uniform and thorough, thereby improving the production efficiency of calcium hydrogen phosphate.
