Description

Technical Field

[0001] The present invention relates to the technical field of potassium nitrate production, and specifically to a filtering and separating device for potassium nitrate production. Background Art

[0002] Potassium nitrate is a colorless transparent orthorhombic crystal or white granular powder, odorless and non-toxic. It is easily soluble in water and hardly soluble in ethanol. In the agricultural field, potassium nitrate is a high-quality compound fertilizer that can provide nitrogen and potassium elements for plants and enhance the stress resistance of plants. Industrially, it is an important raw material for manufacturing products such as gunpowder and glass. It has good water solubility but is hardly soluble in ethanol. When removing impurities from it, for example, cleaning sodium chloride on the surface of potassium nitrate crystals, ethanol needs to be used for rinsing;

[0003] When using ethanol for rinsing, the material needs to be in full contact with ethanol. However, traditional loading devices are difficult to turn over the material, which is likely to result in poor impurity removal effect of potassium nitrate. Moreover, ethanol is extremely volatile. If rinsing is not carried out in a closed environment, ethanol gas volatilizes and is prone to danger. If a closed structure is used for rinsing potassium nitrate, how to stably load and unload materials and how to recycle ethanol become difficult problems to solve. Summary of the Invention

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] ​​​​Please refer to Figures 1-10 , a filtering and separating device for potassium nitrate production, comprising a workbench 1, a bearing assembly, an angle adjustment assembly and a feeding assembly. The bearing assembly includes a bearing box 2 with an upper opening bearing cavity, a filtering box 3, a connecting frame 4, a connecting piece and a first motor 5. The output end of the first motor 5 penetrates the bottom wall of the bearing box 2 and is connected to the connecting frame 4. The bottom wall of the filtering box 3 is connected to the connecting frame 4 through a connecting piece. The bearing cavity is in the shape of a frustum of a cone with a smaller upper part and a larger lower part. The angle adjustment assembly includes a first bracket 6, a first rack 7, a first gear 8, a rotating shaft 9, a second bracket 10, a sliding plate 11 and a feeding assembly. A sliding hole adapted to the sliding plate 11 is provided on the workbench 1. A feeding assembly for driving the sliding plate 11 to move is further provided on the workbench 1. First brackets 6 are symmetrically arranged on the left and right sides of the sliding plate 11. Rotating shafts 9 penetrating the first brackets 6 and connected to the center of the first gear 8 are symmetrically arranged on the left and right sides below the bearing box 2. Two groups of the second brackets 10 are further provided at one end of the workbench 1. A first rack 7 meshing with the first gear 8 is provided on the second bracket 10. An auxiliary frame 12 for supporting the bearing box 2 in a horizontal state is further provided at one end of the sliding plate 11 away from the second bracket 10;

[0039] A feeding assembly for feeding the bearing assembly in a horizontal state is further provided on the workbench 1.

[0040] At first, the sliding plate 11 is located at one end away from the feeding assembly. At this time, the second bracket 10 on the workbench 1 stably supports the first rack 7, and the first bracket 6 on the sliding plate 11 stably supports the bearing box 2 with the rotating shaft 9. At this time, the first gear 8 of the rotating shaft 9 meshes with the first rack 7. In this embodiment, a support seat for supporting the bearing box 2 in a vertical state is further provided on the workbench 1 at the end away from the feeding assembly. The filtering box 3 with an upper opening filtering cavity is connected to the connecting frame 4 of the bearing box 2 through a connecting piece below;

[0041] When feeding, the slide plate 11 moves towards the feeding component driven by the feeding component. During the movement, the first gear 8 drives the rotating shaft 9 to rotate under the drive of the first rack 7 until the bearing box 2 is supported by the auxiliary frame 12 on the slide plate 11 to be in a horizontal state. At this time, the first gear 8 and the first rack 7 are no longer engaged, and the feeding component continues to drive the slide plate 11 to move. The feeding component includes a support plate 13, a sealing cover 14, a feeding component and a liquid supply component. The output end of the feeding component is inserted into the filter box 3 for discharging and distributing materials until the sealing cover 14 closes the bearing box 2 under the support of the support plate 13. At this time, the feeding component stops feeding. Start the liquid supply component and the first motor 5. The first motor 5 drives the filter box 3 to rotate through the connecting frame 4, and the output end of the liquid supply component outputs the cleaning liquid. In this embodiment, the cleaning liquid is anhydrous ethanol, and the anhydrous ethanol fully contacts the continuously tumbling materials, taking out impurities (such as sodium chloride) from the filter box 3. It should be noted that several groups of filter holes are provided on the filter box 3, which can discharge the cleaning liquid with impurities, but retain the materials in the filter box 3. Since the vertical bearing cavity is in the shape of a frustum of a cone with a smaller upper part and a larger lower part, the cleaning liquid with impurities in the horizontal bearing box 2 is concentrated at one end of the bearing cavity far from its opening.

[0042] In this embodiment, the other end of the workbench 1 is provided with the support plate 13, and the support plate 13 is provided with a sealing cover 14 for closing the opening of the bearing box 2. The sealing cover 14 is provided with two groups of symmetrically arranged feeding components. The feeding component includes a second motor 15, a transfer frame 16, a storage box 17 and an auger 18. One end of the transfer frame 16 penetrates through the sealing cover 14, and an auger 18 is arranged in the transfer frame 16. The output end of the second motor 15 penetrates through the other end of the transfer frame 16 and is connected to the auger 18. Above one end of the transfer frame 16 close to the second motor 15, there is the storage box 17. The liquid supply component includes a shunt pipe 19, a liquid supply box 20, a liquid supply pump 21 and a connecting pipe 22. The liquid supply box 20 is arranged on the workbench 1, and the shunt pipe 19 is also embedded in the sealing cover 14. One end of the shunt pipe 19 is provided with several groups of output heads, and the other end of the shunt pipe 19 is connected to the liquid supply pump 21 through the connecting pipe 22. The liquid supply pump 21 is arranged on the liquid supply box 20. The shunt pipe 19 is arranged between the two transfer frames 16 and below the transfer frame 16. The sealing cover 14 provides stable support for the transfer frame 16 and the shunt pipe 19, and at the same time provides stable support for the bearing box 2 in the filtering state. When feeding, start the second motor 15, and the second motor 15 drives the auger 18 to rotate. The materials in the storage box are gradually fed into the filter box 3 as the auger 18 rotates. After the feeding is completed, the second motor 15 stops rotating. Start the liquid supply pump 21, and the liquid supply pump 21 sends the cleaning liquid in the liquid supply box 20 into the connecting pipe 22. The cleaning liquid finally discharges from the output heads of the shunt pipe 19 to wash the materials in the filter box 3.

[0043] During actual use, it is also necessary to collect the cleaning liquid in a timely manner after cleaning is completed and to process the gas in the bearing cavity. For this purpose, a drain pipe 23 and an exhaust pipe 24 are symmetrically arranged on both sides of the end of the bearing cavity far from the opening. An exhaust assembly connected to the output end of the exhaust pipe 24 in a vertical state is arranged on the workbench 1, and a liquid collection assembly connected to the output end of the drain pipe 23 in a vertical state is also arranged below the workbench 1. A support member for supporting the exhaust assembly and the liquid collection assembly is further arranged on the workbench 1. The support member includes a first leg 25, a bottom plate 26, a second leg 27, and a top plate 28. The first legs 25 are arranged at the four corners below the workbench 1, the first legs 25 are connected to the bottom plate 26 below, the top plate 28 is arranged above the feeding assembly, and the second legs 27 connected to the workbench 1 are arranged at the four corners below the top plate 28. The liquid collection assembly includes a liquid collection pipe 29, a lifter 30, a first lifting plate 31, a liquid collection pump 32, and a liquid collection tank 33. The upper and lower ends of the lifter 30 are respectively connected to the first lifting plate 31 and the bottom plate 26. The liquid collection tank 33 is also arranged on the bottom plate 26. One end of the liquid collection pump 32 is connected to the liquid collection tank 33, and the other end of the liquid collection pump 32 is connected to the output end of the liquid collection pipe 29. The input end of the liquid collection pipe 29 penetrates through the first lifting plate 31 and is inserted into the drain pipe 23. The exhaust assembly includes a suction fan 34, an exhaust gas treatment box 35, a gas collecting pipe 36, a second lifting plate 37, a second gear 38, a second rack 39, and a third rack 40. The suction fan 34 and the exhaust gas treatment box 35 are both arranged on the top plate 28. The output end of the suction fan 34 is connected to the exhaust gas treatment box 35, and the input end of the suction fan 34 is connected to the output end of the gas collecting pipe 36. The input end of the gas collecting pipe 36 penetrates through the second lifting plate 37 and the top plate 28 and is inserted into the exhaust pipe 24. The second gear 38 is rotatably arranged on the second leg 27. Second racks 39 meshing with one side of the second gear 38 are arranged on both the upper and lower sides of the first lifting plate 31, and third racks 40 meshing with the other side of the second gear 38 are arranged on both sides below the second lifting plate 37. Initially, when the slide plate 11 is in the initial state, the drain pipe 23 and the exhaust pipe 24 are both in a horizontal state, and the lifter 30 uses a cylinder and is in a contracted state. At this time, the second rack 39 meshes with one side of the second gear 38, the third rack 40 meshes with the other side of the second gear 38, and the second rack 39 and the third rack 40 are both in a vertically parallel state. At this time, the distance between the first lifting plate 31 and the second lifting plate 37 is relatively large, and the top wall of the liquid collection pipe 29 is below the slide plate 11. Therefore, during the movement of the slide plate 11, the liquid collection pipe 29 will not cause movement interference to the slide plate 11. After the bearing box 2 becomes horizontal, the exhaust pipe 24 and the drain pipe 23 are in a vertical state. At this time, the gas collecting pipe 36 is above the exhaust pipe 24, and the equipment will not produce movement interference either. Before performing the flushing operation,The lifter 30 drives the second lifting plate 37 to rise. The part of the liquid collecting pipe 29 passing through the second lifting plate 37 adopts a rigid structure, and the part connecting it with the liquid collecting pump 32 is a flexible structure. A sealing ring in interference fit with the liquid discharge pipe 23 can be arranged on the inner wall of the liquid collecting pipe 29. The liquid collecting pipe 29 is stably inserted into the liquid discharge pipe 23. As the second lifting plate 37 drives the second rack 39 to rise, the second gear 38 drives the third rack 40 to move downward, and the third lifting plate drives the input end of the gas collecting pipe 36 to descend. The gas collecting pipe 36 is similar in structure to the liquid discharge pipe 23 and can be stably and hermetically connected to the exhaust pipe 24. Then, the material is rinsed. By starting the liquid collecting pump 32, the liquid in the bearing cavity can be collected into the liquid collecting tank 33. A gas supply assembly is also arranged on the workbench 1. The gas supply assembly includes a gas supply pump 55, a gas supply tank 56 and a gas supply pipe 57. The gas supply tank 56 is fixed on the workbench 1. One end of the gas supply pump 55 is connected to the gas supply tank 56, and the other end of the gas supply pump 55 is connected to the input end of the gas supply pipe 57. The output end of the gas supply pipe 57 passes through the closing cover 14. By starting the gas supply pump 55, the gas supply pump 55 can send the gas in the gas supply tank 56 into the bearing cavity to balance the air pressure in the bearing cavity. For the gas that may be generated during the rinsing process, the exhaust fan 34 can be started to send the gas into the waste gas treatment tank 35 for treatment. Inert gas can be filled in the gas supply tank 56 to ensure that it does not react with the material in the filter tank 3.,

[0044] During actual use, the feeding assembly includes a closed cover 41, a third motor 42, a worm gear 43, a worm 44 and a screw rod 45. The screw rod 45 is rotatably arranged on both sides inside the sliding hole. The two screw rods 45 pass through the workbench 1 and are connected to the center of the worm gear 43. A closed cover 41 covering the worm gear 43 and the worm 44 is also arranged on the workbench 1. The worm 44 meshes with the two worm gears 43. The output end of the third motor 42 passes through the closed cover 41 and is connected to the worm 44. The first motor 5, the second motor 15 and the third motor 42 all adopt servo motors with precise control. The third motor 42 drives the worm 44 inside the cover to rotate, and the worm 44 can drive the two worm gears 43 to rotate synchronously. At this time, the two screw rods 45 can drive the sliding plate 11 to move. The sliding plate 11 is in a U shape, and the side opening of the sliding plate 11 is arranged at one end away from the feeding assembly to ensure that the bearing box 2 can rotate stably and the liquid discharge pipe 23 and the liquid collecting pipe 29 can be stably connected.,

[0045] During actual use, if the single-sided supported filter box 3 is adopted, there is a situation where the filter box 3 rotates unstably. Therefore, an auxiliary member for supporting the filter box 3 is further provided at one end of the bearing cavity close to the opening. The auxiliary member includes a bearing 46 and a support ring 47. The outer ring of the bearing 46 is connected to the bearing cavity, and the inner ring of the bearing 46 is connected to the support ring 47. Handles 48 are further provided on both the left and right sides of the filter box 3. A notch adapted to the handle 48 is further provided on the support ring 47. An arc-shaped ring 49 is further provided on the inner wall of the opening of the filter box 3. The outer wall of the filter box 3 fits against the inner wall of the support ring 47. The filter box 3 can be conveniently taken out through the handle 48. The connecting member includes a plug 50, an elastic member 51, and a clamping block 52. A slot is provided on the connecting frame 4. The plug 50 is inserted into the slot. Moving grooves are provided on both sides of the plug 50. Both ends of the elastic member 51 are respectively connected to the moving groove and the clamping block 52. A jack adapted to the clamping block 52 is further provided on the plug 50. A slope is further provided at one end of the clamping block 52 away from the elastic member 51. Two groups of slopes of the clamping block 52 are provided. One group of slopes of the clamping block 52 facilitates the stable insertion of the plug 50 into the slot. When the moving groove is aligned with the jack, the elastic member 51 pushes the clamping block 52 into the jack. It should be noted that since two groups of slopes of the clamping block 52 are provided, when the filter box 3 carrying the washed material is in a vertical state, when the filter box 3 is driven upward by the handle 48, the other group of slopes of the clamping block 52 abuts against the card hole, and the elastic member 51 contracts until the clamping block 52 is received into the moving groove, facilitating the separation of the plug 50 from the connecting frame 4. When the filter frame rotates, the support ring 47 connected to the bearing 46 cooperates with the connecting member to stably support the filter box 3, enabling the stable movement of the carried material. The arc-shaped ring 49 prevents the material from detaching from the opening of the filter box 3 in the horizontal state, and at the same time does not affect the subsequent transfer of the material and the cleaning of the inner wall of the filter box 3.

[0046] During actual use, a plurality of groups of friction blocks 53 are further provided at one end of the filter box 3 close to the connecting member. The friction blocks 53 are arranged on the periphery of the connecting member. When the filter box 3 is in a vertical state, the bottom wall of the friction block 53 is lower than the plug 50, and the plug 50 does not contact the inner wall of the bearing cavity, facilitating the transfer and storage of the filter box 3 carrying the material.

[0047] During actual use, an auxiliary cover 54 covering the second rack 39, the second gear 38, and the third rack 40 is further provided on the second leg 27. The auxiliary cover 54 is vertically penetrated to ensure the stability of the assembly of the second rack 39, the second gear 38, and the third rack 40.
