[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a rapid separation and washing processing equipment for potassium nitrate, such as... Figure 1 , Figure 2 and Figure 3 As shown, the potassium nitrate rapid separation and washing processing equipment includes a washing drum 1, a collection funnel 2 connected to the bottom of the washing drum 1, a butterfly valve assembly 3 installed at the bottom of the collection funnel 2, a butterfly valve seat 4 installed at the bottom of the collection funnel 2, a butterfly valve plate 5 rotatably mounted inside the butterfly valve seat 4, a transmission assembly 6 for assisting the rotation of the butterfly valve plate 5 installed on one side of the butterfly valve seat 4, a worm gear 7 rotatably mounted on one side of the butterfly valve plate 5, a servo motor 8 installed at the top of the butterfly valve seat 4, a worm 9 installed at the front end of the shaft of the servo motor 8, and the worm gear 7 and the worm 9 cooperate for transmission.

[0027] By setting the butterfly valve assembly 3, the servo motor 8 is started, and the servo motor 8 drives the worm gear 9 to rotate as a whole. The worm wheel 7 and the worm gear 9 cooperate to drive each other, thereby making the butterfly valve plate 5 rotate as a whole, which can realize the overall discharge of liquid inside the washing drum 1.

[0028] A bracket is installed at the bottom of the washing drum 1, and an overflow groove 201 is opened at the top of the washing drum 1. A liquid outlet pipe 20 is installed on the side of the washing drum 1 near the top, and the liquid outlet pipe 20 is connected to the overflow groove 201. A separation washing chamber is opened inside the washing drum 1 and the collecting funnel 2. A filter screen 16 is installed near the bottom of the separation washing chamber. An auxiliary separation stirring component 10 is installed on the filter screen 16. The stirring component 10 includes a stirring motor 15 installed at the bottom center of the filter screen 16. A rotating rod 13 is fixed at the front end of the shaft of the stirring motor 15. A rotating frame 11 is fixed at the top of the rotating rod 13. A cross 12 is fixed near the top of the washing drum 1. The rotating rod 13 is rotatably embedded in the cross 12. An stirring frame 14 is fixed at the top of the rotating rod 13 corresponding to the top of the filter screen 16. The stirring frame 14 has an arc-shaped rod structure. Several stirring frames 14 are arranged in a circular array with the rotating rod 13 as the center.

[0029] The stirring assembly 10 is activated, and the stirring motor 15 is started. The stirring motor 15 drives the rotating rod 13 to rotate as a whole, and the rotating rod 13 drives the rotating frame 11 to rotate as a whole. This causes the lighter ammonium chloride crystal particles selected at the top to be swept into the overflow tank 201 and discharged through the outlet pipe 20. At the same time, the stirring motor 15 drives the rotating rod 13 to rotate as a whole, which causes the stirring frame 14 to rotate as a whole. This causes the heavier particles deposited on the filter screen 16 to be stirred as the stirring frame 14 rotates, which can effectively achieve rapid separation of light and heavy particles and avoid situations where light and heavy particles cannot be effectively separated inside the washing drum 1.

[0030] like Figure 1 and Figure 4 As shown, an auxiliary liquid inlet assembly 17 is installed in the middle section of the washing drum 1. The water inlet assembly 17 includes an outlet ring 18 arranged vertically. The outlet ring 18 has a ring-shaped structure, and the outlet hole 181 is located on the inner side of the outlet ring 18. The outlet ring 18 is fixed in the washing chamber by a support plate 182. A guide pipe 19 is installed between the two outlet rings 18. The guide pipe 19 extends out of the washing drum 1. The outlet ring 18 has an outlet hole 181. Several outlet holes 181 are arranged in a ring array with the axis of the outlet ring 18 as the center.

[0031] Working principle:

[0032] When the raw materials are washed, potassium chloride and ammonium nitrate are mixed with a portion of the recrystallization separation mother liquor in a certain proportion. The amount of potassium chloride added is calculated based on its content. The temperature is raised to 90-105℃ for reaction. The semi-finished crystal suspension is poured into the outlet ring 18 through the guide pipe 19 and fills the inside of the washing drum 1. The circulating mother liquor is continuously pumped in. Because the potassium nitrate crystal particles are coarser and heavier, they are deposited above the filter screen 16 of the collection funnel 2. Because the ammonium chloride crystal particles are finer and lighter, they float on the surface or upper middle part of the liquid in the pot. At this time, the stirring motor 15 is started. The stirring motor 15 drives the rotating rod 13 to rotate as a whole. The rotating rod 13 drives the rotating frame 11 to rotate as a whole. This causes the lighter ammonium chloride crystal particles selected from the top to be swept into the overflow tank 201 and discharged through the outlet pipe 20. At the same time, the stirring motor 15 drives the rotating rod 13 to rotate as a whole. This causes the stirring frame 14 to rotate as a whole. This causes the heavier particles deposited on the filter screen 16 to be stirred as the stirring frame 14 rotates.

[0033] The servo motor 8 is started, which drives the worm gear 9 to rotate as a whole. The worm wheel 7 and the worm gear 9 cooperate to drive each other, thereby causing the butterfly valve plate 5 to rotate as a whole, which in turn opens the butterfly valve plate 5 and discharges part of the processed liquid. At the same time, washing liquid is poured into the washing drum 1 through the guide pipe 19 to remove excess impurities. After washing, the agitator 14 is rotated so that the crystals are discharged as a whole through the discharge pipe 21.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
