Description

Technical Field

[0001] This utility model relates to the field of potassium nitrate cooling technology, specifically to a high-efficiency cooling device for potassium nitrate production. Background Technology

[0002] Potassium nitrate is an inorganic compound, commonly known as saltpeter or potassium nitrate, with the chemical formula KNO3. It is a potassium nitrate, a colorless, transparent orthorhombic or rhombic crystal or white powder. It is odorless, non-toxic, has a salty taste and a cooling sensation, absorbs very little moisture in the air, does not easily clump, is easily soluble in water, soluble in liquid ammonia and glycerol, and insoluble in anhydrous ethanol and ether. Potassium nitrate is a chlorine-free nitrogen-potassium compound fertilizer with high solubility. Its active ingredients, nitrogen and potassium, can be rapidly absorbed by crops, leaving no chemical residues.

[0003] As shown in the announcement number CN 214495754 U, a high-efficiency cooling device for potassium nitrate production includes a water storage tank, an open-topped box body inside the water storage tank, support legs connected to the bottom of the box body, and an installation through hole on the upper side wall of the box body. A cooling tank with an open top is inserted and fixed into the installation through hole. A cooling pipe is installed at the bottom of the cooling tank, and an outlet pipe is connected to one end of the cooling pipe. This device does not have a reusable reflux mechanism and cannot collect the insufficiently cooled and crystallized potassium nitrate solution and then pump it out and transfer it to the feed pipe. Conventional devices inevitably produce defective products after cooling and crystallizing the potassium nitrate solution, and failure to handle them in time will inevitably lead to resource waste. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient cooling device for potassium nitrate production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency cooling device for potassium nitrate production includes a processing box, a carrying box fixedly mounted at the bottom of the processing box, an upper slot opening at the center of the top of the carrying box, a storage box movably mounted at the top of the carrying box, a flow channel opening at the bottom of the storage box, a filter screen being installed inside the flow channel, and a reflux mechanism fixedly mounted on the side of the carrying box. The reflux mechanism includes a suction pipe, a pump, and a discharge pipe. A suction pipe is fixedly mounted on one side of the carrying box, a pump is fixedly mounted on one side of the top of the suction pipe, and a discharge pipe is fixedly mounted on the other side of the pump.

[0007] Preferably, a cover plate is movably provided at the top of the processing box, and a number of fixing screws are movably provided around the top of the cover plate. The cover plate can be disassembled and installed by rotating the fixing screws.

[0008] Preferably, an inlet pipe is fixedly installed inside the processing box, and one end of the top of the inlet pipe is fixedly connected to one end of the outlet pipe. A closed box is fixedly installed at the bottom of the inlet pipe, and the closed box is movably connected to the storage box. Potassium nitrate liquid can be injected into the closed box through the inlet and fully cooled and crystallized.

[0009] Preferably, an air intake pipe is fixedly installed on one side of the outside of the processing box, a blower is fixedly installed on the side of the air intake pipe, and an air outlet pipe is fixedly installed on the other side of the blower. One end of the air outlet pipe is fixedly connected to the sealed box. By starting the blower through the existing wiring connection, cold air from the outside can be introduced into the sealed box. In the fully sealed state, a large amount of cold air mixes with the mist liquid phase, thereby producing a cooling and evaporation effect, causing the solution to cool and crystallize to precipitate potassium nitrate.

[0010] Preferably, a limiting groove is provided on one side of the bottom of the processing box, and a limiting strip is fixedly provided around the outer circumference of the storage box. The limiting strip is movably connected to the limiting groove, and a sealing plate is fixedly provided on one side of the limiting strip. The perfect fit between the limiting strip and the limiting groove allows the storage box to be perfectly submerged inside the processing box, and the sealing plate limits the movement to keep the device in a fully enclosed state.

[0011] Preferably, a support frame is fixedly installed around the bottom of the processing box, and a base is fixedly installed at the bottom of the support frame. Several expansion screws are movably installed around the inside of the base. The processing box can be stably supported and fixed by connecting the expansion screws to the ground.

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

[0013] This is a high-efficiency cooling device for potassium nitrate production. The device is first fixed in position by connecting to the ground with expansion bolts. Workers then inject potassium nitrate solution into the feed pipe, which sprays out as a mist from the nozzle. A blower is started via existing wiring, drawing air in through the intake pipe and expelling it through the exhaust pipe into the sealed chamber. Because the sealed chamber and storage box fit perfectly, a large amount of cold air mixes with the mist in a fully enclosed state, creating a cooling and evaporation effect. This causes the solution to cool and crystallize, precipitating potassium nitrate. The un-crystallized potassium nitrate mist passes through a filter screen inside the flow channel and finally flows into the carrying box. A pump is then started to draw liquid from the carrying box, which flows through the intake and exhaust pipes back to the feed pipe for secondary cooling and crystallization. Finally, the crystallized potassium nitrate falls into the storage box and can be extracted using a limiting groove.

[0014] This invention relates to a high-efficiency cooling device for potassium nitrate production. The device features a reusable reflux mechanism that collects potassium nitrate solutions that have not been sufficiently cooled and crystallized. These solutions are then pumped out and transported back to the feed pipe. This reusable method improves the success rate of potassium nitrate crystallization. Furthermore, the recyclable nature of the device effectively prevents resource waste, even when the potassium nitrate solution is not sufficiently cooled and crystallized. It is both environmentally friendly and practical. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution:

[0023] A high-efficiency cooling device for potassium nitrate production includes a processing box 1, a bearing box 2 fixedly installed at the bottom of the processing box 1, an upper slot 3 opened at the center of the top of the bearing box 2, a storage box 4 movably installed at the top of the bearing box 2, a flow channel 5 opened at the bottom inside the storage box 4, a filter screen 6 opened inside the flow channel 5, and a reflux mechanism fixedly installed on the side of the bearing box 2. The reflux mechanism includes a suction pipe 7, a pump 8 and a discharge pipe 9. The suction pipe 7 is fixedly installed on one side of the bearing box 2, the pump 8 is fixedly installed on one side of the top of the suction pipe 7, and the discharge pipe 9 is fixedly installed on the other side of the pump 8.

[0024] In this embodiment, preferably, a cover plate 10 is movably provided at the top of the processing box 1, and a plurality of fixing screws 11 are movably provided around the top of the cover plate 10. The cover plate can be disassembled and installed by rotating the fixing screws.

[0025] In this embodiment, preferably, a feed pipe 12 is fixedly installed inside the processing box 1. One end of the feed pipe 12 is fixedly connected to one end of the discharge pipe 9. A closed box 13 is fixedly installed at the bottom end of the feed pipe 12. The closed box 13 is movably connected to the storage box 4. Potassium nitrate liquid can be injected into the closed box through the feed port and fully cooled and crystallized.

[0026] In this embodiment, preferably, an air intake pipe 14 is fixedly installed on one side of the outside of the processing box 1, a blower 15 is fixedly installed on the side of the air intake pipe 14, and an air outlet pipe 16 is fixedly installed on the other side of the blower 15. One end of the air outlet pipe 16 is fixedly connected to the closed box 13. By starting the blower through the existing wiring connection, cold air from the outside can be introduced into the closed box. In the fully enclosed state, a large amount of cold air mixes with the mist liquid phase, thereby producing a cooling and evaporation effect, causing the solution to cool and crystallize to precipitate potassium nitrate.

[0027] In this embodiment, preferably, a limiting groove 17 is provided on one side of the bottom of the processing box 1, and a limiting strip 18 is fixedly provided around the outer periphery of the storage box 4. The limiting strip 18 is movably connected to the limiting groove 17, and a sealing plate 19 is fixedly provided on one side of the limiting strip 18. The limiting strip and the limiting groove fit perfectly, so that the storage box can be perfectly inserted into the processing box. The sealing plate limits the device to be in a fully enclosed state.

[0028] In this embodiment, preferably, a support frame 20 is fixedly provided around the bottom of the processing box 1, and a base 21 is fixedly provided at the bottom of the support frame 20. Several expansion screws 22 are movably provided around the inside of the base 21. The processing box can be stably supported and fixed by connecting the expansion screws to the ground.

[0029] In this embodiment, a high-efficiency cooling device for potassium nitrate production is first fixed in position by connecting it to the ground via expansion bolts 22. Then, the operator injects potassium nitrate solution into the feed pipe 12, which is then sprayed out as a mist from the nozzle. The blower 15 is started via existing wiring, and air is drawn in through the intake pipe 14 and discharged through the exhaust pipe 16 into the sealed chamber 13. Because the sealed chamber 13 and the storage box 4 fit perfectly together, a large amount of cold air mixes with the mist in a fully enclosed state, resulting in a cooling and evaporation effect. This causes the solution to cool and crystallize, precipitating potassium nitrate. The potassium nitrate mist that does not crystallize again passes through the filter screen 6 inside the flow channel 5. Finally, the liquid flows into the carrier tank 2. The pump 8 is started to draw the liquid out of the carrier tank 2 and through the suction pipe 7 and the discharge pipe 9, it finally flows into the feed pipe 12 for secondary cooling and crystallization. The final crystallized potassium nitrate falls into the storage tank 4 and can be extracted through the limiting groove 17. This device has a reusable reflux mechanism that collects the potassium nitrate solution that has not been fully cooled and crystallized, and then pumps it out through the pump 8 and transfers it into the feed pipe 12. The secondary use method can improve the success rate of potassium nitrate crystallization. At the same time, the recyclable method can better avoid resource waste even when the potassium nitrate solution is not fully cooled and crystallized. It is environmentally friendly and practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
