Description

Technical Field

[0001] The utility model belongs to the technical field of evaporation crystallization, and specifically relates to a potassium persulfate vacuum evaporation crystallization device. Background Art

[0002] Potassium persulfate chemical reagent is a white crystalline powder, soluble in water, insoluble in ethanol, with strong oxidizing properties, commonly used as a bleaching agent, oxidant, and polymerization initiator, almost no moisture absorption, good stability at room temperature, easy to store, convenient and safe. The preparation of potassium persulfate is generally prepared with ammonium sulfate and sulfuric acid to prepare an electrolyte and then electrolyze after removing impurities. HSO4 is discharged at the anode to generate peroxydisulfuric acid, which then reacts with ammonium sulfate to generate ammonium persulfate, and then potassium sulfate is added for double decomposition reaction. After cooling, separation, crystallization, and drying, the finished potassium persulfate product is obtained. The crystallization stage is to evaporate and crystallize the prepared wet potassium persulfate;

[0003] Conventional equipment generally puts the prepared potassium persulfate into a heating vessel for direct heating. At this time, the potassium persulfate has just been filtered by filter paper, and most of the water has been removed. It needs to be heated, stirred and evaporated. After the water is separated out, the potassium persulfate forms crystals. In order to ensure the uniformity of heating, the wet potassium persulfate needs to be spread flat in the vessel and stirred continuously. At the same time, proper observation is required during the stirring process to prevent agglomeration. In conventional one-way stirring, the liquid rotates with the stirring blade, and the mixing effect is poor, resulting in poor evaporation and crystallization effect. Utility Model Content

The utility model provides a potassium persulfate vacuum evaporation crystallization device, comprising an evaporation pot for evaporation, and also comprising a material discharge assembly arranged at the bottom of the evaporation pot, a sealing cover is arranged at the top of the evaporation pot, and a bidirectional stirring assembly is arranged at the top of the sealing cover;

[0005] The bidirectional stirring assembly comprises a reduction motor fixed on the top of the sealing cover, and a sleeve fixed at the center of the bottom of the sealing cover. The rotor of the reduction motor passes through the sleeve and is fixed with four-corner brackets.

[0006] As a potassium persulfate vacuum evaporation crystallization device of the utility model, preferably, an upper active gear disc and a lower active gear disc are fixed on the sleeve, and positive stirring blades are arranged at two symmetrical corners of the four-corner bracket through support rods.

[0011] As a potassium persulfate vacuum evaporation crystallization device of the utility model, preferably, a cylinder is provided on the side wall of the evaporator, and a piston rod of the cylinder is movably connected to a feed cover.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The reduction motor drives the four-corner bracket to rotate, and the positive stirring blade is driven to rotate forward through the support rod. At this time, the four-corner bracket drives the left driven gear disc and the right driven gear disc to rotate.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 As shown;

[0029] A potassium persulfate vacuum evaporation crystallization device comprises an evaporation pot 1 for evaporation.

[0030] In this embodiment: in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "in order to ensure the uniformity of heating, the wet potassium persulfate needs to be spread evenly in the container, and it needs to be stirred continuously. At the same time, proper observation is required during the stirring process to prevent agglomeration. In traditional one-way stirring, the liquid rotates with the stirring blades, and the mixing effect is poor, resulting in poor evaporation and crystallization effect." In combination with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a two-way stirring component 4 is added on this basis.

[0031] like Figure 1-4 As shown in the figure;

[0032] In combination with the above content, in order to improve the mixing efficiency and the effect of evaporation and crystallization, it also includes a feeding assembly 2 arranged at the bottom of the evaporation pot 1, a sealing cover 3 is arranged at the top of the evaporation pot 1, and a two-way stirring assembly 4 is arranged at the top of the sealing cover 3;

[0033] The bidirectional stirring assembly 4 includes a reduction motor 41 fixed on the top of the sealing cover 3 and a sleeve 42 fixed at the center of the bottom of the sealing cover 3 . The rotor of the reduction motor 41 passes through the sleeve 42 and is fixed with four-corner brackets 43 .

[0034] In an optional embodiment, an upper driving gear disc 421 and a lower driving gear disc 422 are fixed on the sleeve 42, and two symmetrical corners of the four-corner bracket 43 are provided with positive stirring blades 432 through support rods 431, and the other two symmetrical corners of the four-corner bracket 43 are respectively provided with a left rotating shaft 433 and a right rotating shaft 434 through bearings, a left driven gear disc 435 is provided on the top of the left rotating shaft 433, and a left reverse stirring blade 436 is fixedly provided at the bottom thereof, a right driven gear disc 437 is provided on the top of the right rotating shaft 434, and a right reverse stirring blade 438 is fixedly provided at the bottom thereof, the upper driving gear disc 421 is connected to the left driven gear disc 435 through a left toothed belt 5, and the lower driving gear disc 422 is connected to the right driven gear disc 437 through a right toothed belt 6.

[0035] In this implementation scheme: the reduction motor 41 drives the four-corner bracket 43 to rotate, and at this time, the positive stirring blade 432 is driven to rotate forward through the support rod 431. At this time, the four-corner bracket 43 drives the left driven gear plate 435 and the right driven gear plate 437 to rotate. Since the upper active gear plate 421 is connected to the left driven gear plate 435 through the left toothed belt 5, and the lower active gear plate 422 is connected to the right driven gear plate 437 through the right toothed belt 6, the upper active gear plate 421 and the lower active gear plate 422 are driven to rotate in the opposite direction, thereby driving the left reverse stirring blade 436 and the right reverse stirring blade 438 to rotate in the opposite direction.

[0036] In an optional embodiment, the unloading assembly 2 includes a unloading port 21 opened at the bottom of the evaporating pot 1, and a movable seat 22 arranged on the evaporating pot 1, and a unloading cover 23 is movably arranged on the movable seat 22 to seal the unloading port 21, and a cylinder 24 is arranged on the side wall of the evaporating pot 1, and the piston rod of the cylinder 24 is movably connected to the unloading cover 23.

[0037] Working principle of this utility model:

[0038] The reduction motor 41 drives the four-corner bracket 43 to rotate, and at this time, the positive stirring blade 432 is driven to rotate forwardly through the support rod 431. At this time, the four-corner bracket 43 drives the left driven gear disc 435 and the right driven gear disc 437 to rotate. Since the upper active gear disc 421 is connected to the left driven gear disc 435 through the left toothed belt 5, and the lower active gear disc 422 is connected to the right driven gear disc 437 through the right toothed belt 6, the upper active gear disc 421 and the lower active gear disc 422 are driven to rotate in the opposite direction, and then the left reverse stirring blade 436 and the right reverse stirring blade 438 are driven to rotate in the opposite direction. Through the positive rotation of the positive stirring blade 432 and the reverse rotation of the left reverse stirring blade 436 and the right reverse stirring blade 438, the liquid is collided and mixed inside the evaporator 1, the mixing efficiency is improved, and the evaporation and crystallization effect is good.

[0039] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
