Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fertilizer production and processing, and particularly relates to a calcium superphosphate mixing device. Background Art

[0002] Calcium superphosphate, also known as single superphosphate, ordinary superphosphate, calcium superphosphate lime, and superphosphate lime, is a phosphate fertilizer. Its main component is monocalcium phosphate (Ca(H2PO4)2·H2O), and the secondary component is calcium sulfate (CaSO4). In addition, there are also small amounts of free phosphoric acid, free sulfuric acid, dicalcium phosphate, and iron phosphate, aluminum phosphate, magnesium phosphate, etc. The main operation for producing calcium superphosphate is to put sulfuric acid and phosphate rock powder into a mixing device for reaction. Generally, there are too few stirring devices in the calcium superphosphate mixing device, and the reactants in the corners cannot react fully.

[0003] Chinese Patent with application number CN201620945633.4 discloses a calcium superphosphate mixing device, which includes a mixing tank, a feed inlet, a discharge outlet, a stirring device, a motor, and a transmission wheel. The feed inlet is arranged at one end of the mixing tank and above the mixing tank, the discharge outlet is arranged at the other end of the mixing tank and on the side of the mixing tank. One end of the stirring device is arranged inside the mixing tank, and the other end is connected to the transmission wheel. The transmission wheel is connected to the motor through a belt. There are more than 6 stirring devices, and the numbers of the transmission wheel and the motor are the same as that of the stirring device.

[0004] With further research by the applicant, it is found that although this technical solution can stir sulfuric acid and phosphate rock placed in the mixing tank, accelerate the reaction time, and avoid waste of materials, due to the limitation of the structure of its stirring device, the stirring and mixing efficiency still needs to be improved.

[0027] As Figure 1 - Figure 2 shown, a calcium superphosphate mixing device of the present utility model includes a mixing tank 1, a power member 3, and a stirring mechanism 4;

[0028] Among them, the mixing tank 1 has a feed inlet 10 and a discharge outlet 11;

[0029] The stirring mechanism 4 is rotatably arranged in the mixing tank 1 under the drive of the power member 3. The stirring mechanism 4 has several groups and is arranged along the length direction of the mixing tank 1;

[0030] The present utility model can make the reaction between sulfuric acid and phosphate rock more sufficient, avoid material waste, and improve the quality of calcium superphosphate;

[0031] A cover plate 20 is arranged on the upper part of the mixing tank 1, and a lifting plate 21 is fixed above the cover plate 20. When the stirring mechanism 4 in the mixing tank 11 is working, the cover plate 20 is covered. When it is necessary to check or clean the mixing tank 1, the cover plate 20 can be removed. The purpose of the lifting plate 21 is to facilitate the removal of the cover plate 20.

[0032] Specifically, the stirring mechanism 4 includes stirring frames 40 arranged perpendicular to each other. Each stirring frame 40 has several groups of disturbing plates 41 arranged along the length or width direction of the stirring frame 40;

[0033] The stirring frame 40 is connected to the power member 3 through the cooperation of a rotating shaft 42 and a gear set 5.

[0034] The disturbing plates 41 are symmetrically distributed on the inner side of the stirring frame 40, and the inclination directions of the disturbing plates 41 on each side are opposite.

[0035] The multiple stirring mechanisms 4 provided by the present utility model can continuously stir the materials in the mixing tank 1, enabling the reaction to proceed more fully. Among them, each stirring mechanism 4 can, by arranging stirring frames 40 arranged perpendicular to each other, fully mix the materials at the same depth and different depths in the mixing tank 1 under the drive of the power component 3 to rotate. Such an arrangement further increases the material mixing capacity of the stirring mechanism 4, and the material reaction is more sufficient and uniform.

[0036] Among them, the gear set 5 includes a driving gear 50 connected to the power component 3 and a driven gear 51 meshing with the driving gear 50, and the rotating shaft 42 is connected to the driven gear 51.

[0037] The stirring frame 40 in this embodiment is rectangular. The feed inlet 10 is cylindrical.

[0038] In addition, to enhance the stability of the stirring mechanism 4, a connecting plate 43 can be arranged in the mixing tank 1, and the stirring frame 40 is connected to the mixing tank 1 through the connecting plate 43.

[0039] In addition, universal wheels are installed at the bottom of the mixing tank 1, which can facilitate the movement of the entire device and reduce the handling cost.

[0040] The above-mentioned power component 3 is a servo motor, and also has a corresponding reduction gearbox transmission structure. Moreover, the rotation speed of the transmission shaft should not be too fast or too slow. Generally, 140 r / min is adopted for the convenience of configuring the reduction gearbox.

[0041] When using this device, sulfuric acid and phosphate rock are added from the material feed inlet 10, and the power component 3 is turned on. Its servo motor drives the stirring mechanism 4 to rotate. The sulfuric acid and phosphate rock react under the stirring action of the stirring mechanism 4. At the same time, the substances obtained after the reaction are taken out by the staff from the discharge port 11, and the intermediate products after the reaction are subjected to the next operation.

[0042] The above-mentioned fixed connection without specific designation can be connection methods such as riveting, welding, and bolt connection, and the movable connection can be connection methods such as hinge connection.

[0043] The above are only the embodiments of the present utility model. Specific structures and common knowledge such as characteristics well-known in the art are not described in detail herein. Those of ordinary skill in the art know all the general technical knowledge in the technical field to which the utility model pertains before the filing date or the priority date, are able to acquire all the prior arts in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given by this application, complete and implement this solution in combination with their own abilities. Some typical well-known structures or well-known methods should not become obstacles for those of ordinary skill in the art to implement this application. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
