Description
Technical Field
[0001] The utility model relates to the field of crystallization tanks, and particularly relates to a stirring paddle structure of an intermittent crystallization tank. Background Art
[0002] In recent years, with the continuous expansion of the application market of water-soluble fertilizers and the demand for lithium iron phosphate as the cathode material of new energy, the market demand for industrial monoammonium phosphate has been increasing continuously. In order to better meet the market demand, each manufacturer tries to improve the output of each crystallization tank product. Currently, intermittent crystallization tanks are generally used in crystallizers. In order to improve the crystallization yield and obtain relatively uniform and larger crystals, by adjusting the rotation speed of the stirring paddle or the form of the stirring paddle, the stirring paddle of a general crystallization tank usually adopts a frame-type stirring paddle. Because crystals are likely to form on the wall of the crystallization tank, the frame-type stirring paddle can reduce the wall-forming phenomenon. However, due to the structural form, the frame-type stirring paddle has some problems, such as uneven stirring, easy formation of dead corners at the bottom, and a relatively long cooling time. Summary of the Utility Model

[0018] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.
[0019] Among them, the same reference numerals in the drawings all refer to the same components.
[0020] As Figure 1-2 shown, the present utility model provides a stirring paddle structure for an intermittent crystallization tank, including a tank body 1 and a driving assembly 2. The driving assembly 2 is arranged at the top end of the tank body 1 and extends vertically downward into the tank body 1. It is characterized in that a stirring structure 3 is arranged inside the tank body 1;
[0021] The stirring structure 3 includes a frame - type stirring paddle 31. The frame - type stirring paddle 31 is in transmission connection with the output end of the driving assembly 2. On both sides of each cross - bar of the frame - type stirring paddle 31, a thickening member 32 is provided, and at the bottom end of each blade of the frame - type stirring paddle 31, a bottom plate 33 is provided.
[0022] In this embodiment, the driving assembly 2 on the tank body 1 drives the stirring structure 3 in the tank body 1 to rotate, so as to stir the raw materials in the tank body 1.
[0023] In the stirring structure 3, each cross - bar of the frame - type stirring paddle 31 is thickened by the thickening member 32 while the thickness of the vertical bars remains unchanged, and a bottom plate 33 is installed at the bottom of each blade. By adding the thickening member 32 and the bottom plate 33, the stirring structure 3 can improve the stirring efficiency of the raw materials, make the stirring more uniform, thereby reducing the wall thickness of the crystallization tank and greatly reducing the cleaning work. The thicker stirring structure 3 with a smaller gap from the inner bottom wall of the tank body 1 can increase the degree of stirring of the raw materials, thus greatly shortening the cooling time.
[0024] Further, the thickening member 32 is parallel to the corresponding cross - bar of the frame - type stirring paddle 31. The thickening member 32 is in a "U" shape, and its two short sides are fixedly connected to the cross - bar.
[0025] Further, the lengths of the two short sides of the thickening member 32 are both 25mm - 45mm.
[0026] In this embodiment, thickening members 32 are fixed on both sides of each cross - bar of the frame - type stirring paddle 31. The two short sides of the thickening member 32 are fixedly connected to the cross - bar, and the sum of the lengths of the short sides of the two thickening members 32 is the thickness of the thickened cross - bar.
[0027] Further, the top end of the bottom plate 33 is fixedly connected to the corresponding blade of the frame - type stirring paddle 31. The bottom end shape of the bottom plate 33 is adapted to the inner bottom wall of the tank body 1, and there is a gap between it and the inner bottom wall of the tank body 1.
[0028] Further, the bottom plate 33 is made of stainless steel, and the distance between its bottom end and the inner bottom wall of the tank body 1 is 80mm - 120mm. Through - holes 34 are arranged in an array on the surface of the bottom plate 33.
[0029] In this embodiment, the bottom end shape of the bottom plate 33 is adapted to the inner bottom wall of the tank body 1 to facilitate the rotation of the bottom plate 33, and the through - holes 34 on the bottom plate 33 facilitate the passage of the raw materials to be stirred.
[0030] Further, the driving assembly 2 includes a driving motor 21 and a shaft rod 22. The driving motor 21 is arranged at the top end of the tank body 1, and its output shaft is vertically downward. The shaft rod 22 is arranged in the tank body 1 and is coaxially connected to the output shaft of the driving motor 21 through a coupling. The frame - type stirring paddle 31 is fixedly connected to the outer periphery of the shaft rod 22.
[0031] In this embodiment, the driving motor 21 of the prior art is adopted to drive the shaft rod 22 to rotate, and the shaft rod 22 drives the stirring structure 3 to stir the raw materials in the tank body 1.
[0032] The utility model relates to a stirring paddle structure of an intermittent crystallization tank. The cross bar of the frame type stirring paddle is thickened, and the distance between the frame type stirring paddle and the inner bottom wall of the tank body is reduced through the bottom plate, so that when the driving component drives the stirring structure to rotate and stir the raw materials, the wall thickness of the tank wall can be reduced, the stirring can be more uniform, and large and uniform crystals can be obtained.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
