[0021] The present invention has the following beneficial effects:

[0022] (1) The present invention provides an intelligent salt and nitrate co-production evaporation device. During the operation of the device, the mother liquor is first transported to the inside of the salt precipitation cylinder through the feed pipe; the heat energy generated by the heating annular box is transmitted to the inner wall of the salt precipitation cylinder through the outer wall of the salt precipitation cylinder, heating and evaporating the mother liquor in the cylinder, and promoting the crystallization and precipitation of the salt dissolved in the mother liquor; then the driving motor is started, and the motor rotates forward to drive the rotating shaft to rotate, and the rotating shaft drives the connected circular blocks to rotate synchronously, thereby driving the multiple mixing plates installed thereon to rotate; the mixing plates achieve a stirring effect on the mother liquor during the rotation process, and at the same time, their edges move closely against the inner wall of the salt precipitation cylinder, effectively removing the salt scale deposits attached to the inner wall and preventing the occurrence of scaling; in addition, the stirring effect of the mixing plates causes the internal temperature of the mother liquor to quickly tend to be evenly distributed, avoiding the occurrence of local high-temperature areas, thereby improving the temperature control accuracy and process stability; while the rotating shaft rotates forward, through the threaded transmission action of the threaded block, The mixing plate and the round block move downward in the axial direction; when the round block contacts the annular plate, it pushes the adaptive spring to compress and deform; at this time, the threaded block is in a state of partially disengaging from the threaded engagement of the inner wall of the salt precipitation cylinder, and the restoring force of the adaptive spring ensures that the mixing plate assembly maintains a stable axial position during continuous rotation, preventing jamming caused by excessive downward movement; at the same time, the rotation of the mixing plate also drives the rotating rod connected to it to rotate together, further driving the multiple stirring blades installed on the rotating rod to rotate; the stirring blades produce irregular self-rotation motion under the action of the flow resistance of the mother liquor, thereby enhancing the secondary stirring effect of the mother liquor; this self-rotation disturbance not only accelerates the homogenization process of the temperature field inside the mother liquor, but also cooperates with the stirring action of the mixing plate to effectively regulate the growth process of the salt crystals, ensuring that the precipitated salt crystals are uniform in shape and consistent in particle size, significantly reducing the possibility of salt particles agglomerating to form large pieces of solid salt, thereby improving the quality and processability of the final salt product;

[0023] (2) The present invention provides an intelligent salt and saltpeter co-production evaporation device. During the evaporation and crystallization process of the mother liquor in the salt precipitation cylinder, the precipitated salt enters the interior of the circular collecting cylinder through the filter hole and completes the crystallization precipitation process therein simultaneously. In order to prevent the salt crystals from agglomerating during the process, the driving motor continues to run at this stage, driving the rotating shaft to rotate, and driving the auxiliary blades installed thereon to rotate synchronously, continuously stirring the salt slurry in the circular collecting cylinder, thereby effectively suppressing the aggregation behavior between the salt crystals and ensuring that the precipitated salt body is uniform in shape and well dispersed. After the mother liquor completes the initial salt separation in the salt precipitation cylinder, the intelligent solenoid valve configured on the discharge pipe is opened to transfer the residual mother liquor through the filter hole and the discharge pipe to the subsequent processing unit, the salt precipitation cylinder, for the next step of component separation. In this process, the filter hole plays a role in solidification. The liquid separation effect intercepts the solid salt that has precipitated and retained in the salt precipitation cylinder, thereby realizing effective separation of mother liquor and salt crystals; subsequently, the driving motor switches to reverse mode, driving the rotating shaft to rotate in the opposite direction, and driving the round block to move upward along the axial direction through the transmission structure; the upward movement of the round block further drives the mixing plate and the annular sealing plate to move upward synchronously; during the rising process of the mixing plate, its edge continues to move in contact with the inner wall of the salt precipitation cylinder, scraping off the scaling salt layer attached to the cylinder wall, causing it to fall off and deposited at the bottom of the salt precipitation cylinder, thereby realizing automatic scale cleaning function, avoiding the decrease in heat transfer efficiency and the risk of equipment blockage caused by scaling; at the same time, as the annular sealing plate rises, the discharge chute originally closed by it is opened, so that a connecting channel is formed between the storage box and the discharge chute, which is convenient for the discharge and collection of the precipitated salt product;

[0024] (3) The present invention provides an intelligent salt and saltpeter co-production evaporation device. When the telescopic ladder slide plate is in contact with the annular sealing plate, the compression spring is in an energy storage state due to pressure; when the telescopic ladder slide plate moves with the rotating shaft and separates from the contact surface of the annular sealing plate, the compression spring pushes the telescopic ladder slide plate outward under the action of its restoring force, and makes its end fit the inner wall surface of the salt precipitation cylinder; when the rotating shaft rotates, it drives the telescopic ladder slide plate to rotate synchronously; at the same time, the rotating special-shaped plate also rotates with the shaft system; during the rotation process, the telescopic ladder slide plate and the rotating special-shaped plate generate centrifugal force due to high-speed rotation, and the centrifugal force throws the salt crystals deposited at the bottom of the salt precipitation cylinder radially outward to the inner wall area of ​​the salt precipitation cylinder, and finally transports them to the storage box through the opened discharge chute for centralized collection; at the same time, the salt crystals precipitated inside the circular collecting cylinder are discharged through the discharge chute. The tube is transferred to the nitration cylinder to complete the segmented collection process of the salt product; the mother liquor entering the nitration cylinder will continue to undergo the evaporation and crystallization process inside it to achieve the selective precipitation of nitrate substances; at this time, the drive motor is started again to make the rotating shaft rotate forward, driving the mixing plate to reset to the initial working position; since the nitration cylinder and the salt precipitation cylinder have internal component designs with symmetrical structure and consistent functions, driven by the same rotating shaft, the stirring components and auxiliary scraping and discharging mechanisms inside the two operate synchronously, ensuring that salt and nitrate can complete crystallization, separation and discharging operations respectively in their respective independent reaction chambers according to the same process logic; this structural design effectively avoids the traditional process of requiring complex separation treatment after salt and nitrate co-precipitate in the same container, significantly improving the operating efficiency and product purity of the system, and realizing efficient integrated processing of salt-nitrate continuous graded crystallization;

[0025] (4) The present invention provides an intelligent salt and nitrate co-production evaporation device. After the nitrate substance is crystallized and precipitated, the intelligent electromagnetic valve configured at the inlet end of the circulation pump is opened, the circulation pump is started, and the mother liquor from which the nitrate precipitation has been completed in the nitrate precipitation cylinder is transported back to the salt precipitation cylinder for a new round of salt crystallization operation; during this process, an appropriate amount of untreated fresh mother liquor can be added to the salt precipitation cylinder to achieve continuous graded precipitation of salt, thereby improving resource utilization and system operation efficiency; during the graded crystallization process of salt and nitrate, steam is supplied to the steam box through a steam pump, and high-temperature steam is input from the steam box to the heating annular boxes arranged outside the salt precipitation cylinder and the nitrate precipitation cylinder, respectively, to provide a controllable heat source for the two reaction chambers; at the same time, a temperature detector is used to monitor the temperature during the heating process. The system conducts real-time monitoring and feedback control to ensure that salt and nitrate are stably precipitated within their respective optimal crystallization temperature ranges; as the evaporation and crystallization process proceeds, a large amount of steam is generated inside the salt precipitation cylinder and the nitrate precipitation cylinder due to evaporation of the liquid, and the steam is transported to the rectangular recovery box through the recovery pipe for centralized collection; when the internal pressure of the rectangular recovery box is higher than the internal pressure of the steam box, the resulting pressure difference pushes the T-shaped hollow plate to slide toward the steam box, and the limit spring is stretched and stores elastic potential energy in this process; when the exhaust groove on the T-shaped hollow plate moves into the interior of the steam box, the waste heat steam in the rectangular recovery box re-enters the steam box through the exhaust groove, thereby realizing efficient recovery and recycling of steam, effectively reducing system energy consumption, and improving overall thermal energy utilization.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1-8 As shown, the present invention is an intelligent salt and saltpeter co-production evaporation device, comprising a fixing frame 1, and further comprising:

[0040] A mixing mechanism is provided on a fixed frame 1. The mixing mechanism includes a salt precipitation cylinder 101 and a nitrate precipitation cylinder 102 fixedly mounted on the fixed frame 1. A driving motor 103 is fixedly mounted on the bottom inner wall of the fixed frame 1. A rotating shaft 104 is fixedly mounted on the output shaft of the driving motor 103. The rotating shaft 104 rotates through the nitrate precipitation cylinder 102. The top end of the rotating shaft 104 extends into the salt precipitation cylinder 101 and is rotatably connected to the top inner wall of the salt precipitation cylinder 101.

[0041] Two separation mechanisms, the two separation mechanisms are respectively arranged on the salt separation cylinder 101 and the nitrate separation cylinder 102, the separation mechanism includes a storage box 2 fixedly mounted on the inner wall of the back of the fixing frame 1, and a discharge chute 201 is opened on the salt separation cylinder 101;

[0042] The recovery mechanism is arranged on the fixed frame 1. The recovery mechanism includes a circulation pump 3 fixedly installed on the inner wall of the bottom of the fixed frame 1. The input end of the circulation pump 3 is communicated with the nitrate precipitation cylinder 102, and the output end of the circulation pump 3 is communicated with the salt precipitation cylinder 101. A feed pipe 301 is fixedly installed on the top of the salt precipitation cylinder 101, and a steam box 302 is fixedly installed on the right inner wall of the fixed frame 1.

[0043] like Figure 4 As shown, the mixing mechanism also includes two mixing components, which are respectively arranged in the salt precipitation cylinder 101 and the nitrate precipitation cylinder 102. The mixing component includes a rectangular chute 105 opened on the rotating shaft 104, and a round block 106 is slidingly sleeved on the rectangular chute 105, and a number of mixing plates 107 are fixedly installed on the round block 106.

[0044] Then, the driving motor 103 is started, and the motor drives the rotating shaft 104 to rotate in the forward direction, and the rotating shaft drives the connected round block 106 to rotate synchronously, thereby driving the multiple mixing plates 107 installed thereon to rotate; the mixing plates achieve a stirring effect on the mother liquor during the rotation process, and at the same time, their edges move closely against the inner wall of the salt precipitation cylinder 101, effectively removing salt scale deposits attached to the inner wall and preventing the occurrence of scaling.

[0045] like Figure 4 As shown, the mixing assembly also includes threaded blocks 108 fixedly mounted on the mixing plates 107 respectively. The outer walls of several threaded blocks 108 are threadedly connected to the inner wall of the salt precipitation cylinder 101. The corresponding two threaded blocks 108 and the corresponding two mixing plates 107 are respectively rotatably mounted with rotating rods 109, and the two rotating rods 109 are respectively rotatably sleeved with several groups of stirring blades 110.

[0046] The rotation of the mixing plate 107 also drives the rotating rod 109 connected to it to rotate together, further driving the multiple stirring blades 110 installed on the rotating rod to rotate; the stirring blades produce irregular self-rotation motion under the action of the mother liquor flow resistance, thereby enhancing the secondary stirring effect on the mother liquor.

[0047] like Figure 4 As shown, the mixing assembly further includes a fixed round block 111 fixedly sleeved on the rotating shaft 104 , an adaptable spring 112 is fixedly mounted on the top of the fixed round block 111 , and a circular plate 113 is fixedly mounted on the top of the adaptable spring 112 .

[0048] When the round block contacts the annular plate 113, it pushes the adaptive spring 112 to undergo compression deformation; at this time, the threaded block 108 is in a state of partially disengaging from the threaded engagement of the inner wall of the salt precipitation cylinder 101, and the restoring force of the adaptive spring ensures that the mixing plate assembly maintains a stable axial position during continuous rotation, preventing jamming caused by excessive downward movement.

[0049] like Figure 6 As shown, the separation mechanism includes an annular sealing plate 202 fixedly mounted on the bottom of several mixing plates 107 , the discharge chute 201 is communicated with the storage box 2 , and several rotating special-shaped plates 203 are fixedly mounted on the outer wall of the fixed circular block 111 .

[0050] The upward movement of the round block 106 further drives the mixing plate 107 and the annular sealing plate 202 to move upward synchronously; during the upward movement of the mixing plate 107, its edge continues to move in contact with the inner wall of the salt precipitation cylinder 101, scraping off the scaling salt layer attached to the cylinder wall, causing it to fall off and deposit at the bottom of the salt precipitation cylinder, thereby realizing the automatic scaling function.

[0051] like Figure 6 and Figure 7 As shown, the separation mechanism further includes a circular collecting cylinder 204 fixedly mounted on the bottom of the salt precipitation cylinder 101, a plurality of filter holes 205 are provided on the inner wall of the bottom of the salt precipitation cylinder 101, and the plurality of filter holes 205 are all connected to the circular collecting cylinder 204, and a plurality of auxiliary leaves 206 are fixedly mounted on the rotating shaft 104;

[0052] A discharge pipe 207 is fixedly installed at the bottom of the circular collecting cylinder 204, and the bottom end of the discharge pipe 207 is connected to the nitrate separation cylinder 102.

[0053] After the mother liquor completes the preliminary salt separation in the salt separation cylinder 101, the intelligent solenoid valve 208 configured on the discharge pipe 207 is opened to transfer the residual mother liquor through the filter hole 205 and the discharge pipe 207 to the subsequent processing unit, the salt separation cylinder 102, for the next step of component separation.

[0054] like Figure 6 and Figure 7 As shown, the separation mechanism also includes compression springs 209 fixedly mounted on the inner walls of the rotating special-shaped plates 203 on the sides close to each other, and a telescopic ladder slide 210 is fixedly mounted on the ends of the several compression springs 209 away from each other. The bottom ends of the several rotating special-shaped plates 203 are in contact with the bottom inner wall of the salt precipitation cylinder 101, the bottom ends of the several telescopic ladder slides 210 are in contact with the bottom inner wall of the salt precipitation cylinder 101, and the sides of the several telescopic ladder slides 210 away from each other are in contact with the annular sealing plate 202.

[0055] When the telescopic ladder slide 210 is in contact with the annular sealing plate 202, the compression spring 209 is in an energy storage state due to pressure; when the telescopic ladder slide 210 moves with the rotating shaft and separates from the contact surface of the annular sealing plate 202, the compression spring 209 pushes the telescopic ladder slide 210 outward under the action of its restoring force, and makes its end fit the inner wall surface of the salt precipitation cylinder 101.

[0056] like Figure 2 and Figure 8 As shown, the recovery mechanism includes a temperature control component and two recovery components. The temperature control component includes a heating annular box 303 fixedly mounted on the outer wall of the salt precipitation cylinder 101 and the nitrate precipitation cylinder 102, and two steam pumps 304 are fixedly mounted on the right inner wall of the fixed frame 1. The output ends of the two steam pumps 304 are respectively communicated with the two heating annular boxes 303, and the input ends of the two steam pumps 304 are both communicated with the steam box 302. Temperature detectors 305 are respectively fixedly mounted on the two heating annular boxes 303, and the two temperature detectors 305 extend into the salt precipitation cylinder 101 and the nitrate precipitation cylinder 102, respectively.

[0057] An intelligent solenoid valve 208 is provided on the input end of the circulation pump 3 and the discharge pipe 207 respectively.

[0058] During the fractional crystallization process of salt and nitre, steam is supplied to the steam box 302 through the steam pump 304, and the steam box 302 inputs high-temperature steam to the heating annular boxes 303 arranged outside the salt precipitation cylinder 101 and the nitre precipitation cylinder 102 respectively, providing a controllable heat source for the two reaction chambers.

[0059] like Figure 8 As shown, the recovery components are respectively arranged on the salt separation cylinder 101 and the nitrate separation cylinder 102. The recovery components include a recovery pipe 306 fixedly installed on the top of the nitrate separation cylinder 102, and a rectangular recovery box 307 fixedly installed on the steam box 302. The end of the recovery pipe 306 is connected to the rectangular recovery box 307.

[0060] A large amount of steam is generated inside the salt separation cylinder 101 and the nitrate separation cylinder 102 due to the evaporation of liquid, and the steam is transported to the rectangular recovery box 307 through the recovery pipe 306 for centralized collection.

[0061] like Figure 8 As shown, the recycling component also includes a limit spring 308 fixedly installed on the left inner wall of the rectangular recycling box 307, a T-shaped hollow plate 309 is slidably installed in the rectangular recycling box 307, and the right side of the T-shaped hollow plate 309 slides and extends outside the rectangular recycling box 307, and the right end of the limit spring 308 is fixedly connected to the right inner wall of the T-shaped hollow plate 309, and the front inner wall and the back inner wall of the T-shaped hollow plate 309 are respectively provided with exhaust grooves 310.

[0062] When the internal pressure of the rectangular recovery box 307 is higher than the internal pressure of the steam box 302, the resulting pressure difference pushes the T-shaped hollow plate 309 to slide toward the steam box 302, and the limit spring 308 is stretched and stores elastic potential energy in this process; when the exhaust groove 310 on the T-shaped hollow plate 309 moves into the interior of the steam box 302, the waste heat steam in the rectangular recovery box 307 re-enters the steam box 302 through the exhaust groove 310, thereby realizing efficient recovery and recycling of steam, effectively reducing system energy consumption, and improving overall thermal energy utilization.

[0063] When in use, the mother liquor is first discharged into the salt precipitation cylinder 101 from the feed pipe 301, and the heat in the heating annular box 303 is transferred from the outer wall of the salt precipitation cylinder 101 to the inner wall of the salt precipitation cylinder 101, so that the mother liquor in the salt precipitation cylinder 101 is evaporated to precipitate salt, and then the driving motor 103 is started. The forward direction of the driving motor 103 drives the rotating shaft 104 to rotate, and the rotating shaft 104 drives the round block 106 to rotate, and the round block 106 drives several mixing plates 107 to rotate. The rotation of the mixing plates 107 stirs, and the rotation of the mixing plates 107 not only scrapes the inner wall of the salt precipitation cylinder 101 to prevent salt from scaling on the inner wall of the salt precipitation cylinder 101 due to local high temperature, but also stirs the mother liquor inside the salt precipitation cylinder 101 so that the mother liquor is fully mixed under stirring to quickly reach the average temperature, thereby preventing the existence of local high temperature in the mother liquor and facilitating the control of the temperature of the mother liquor. When rotating forward, the mixing plate 107 and the circular block 106 will move downward under the action of the threaded block 108, and the annular plate 113 contacting the circular block 106 will cause the adaptive spring 112 to be compressed and deformed. At this time, since the threaded block 108 is in a state of semi-detached from the thread on the inner wall of the salt precipitation cylinder 101, the elastic force of the adaptive spring 112 will ensure that the mixing plate 107 rotates continuously without moving downward or getting stuck. When the mixing plate 107 rotates, the rotating rod 109 will be driven to rotate, and the rotating rod 109 will drive a number of stirring blades 110 to rotate. The stirring blades 110 will rotate irregularly under the resistance of the mother liquor. The rotation of the stirring blades 110 will further strengthen the stirring of the mother liquor, which can not only speed up the speed of reducing the temperature difference of the mother liquor, but also control the precipitated salt when the mixing plate 107 rotates, ensuring that the precipitated salt is uniform in shape and there is no agglomeration of solid salt, thereby improving the quality of salt precipitation.

[0064] When the mother liquor in the salt precipitation cylinder 101 is precipitated, the salt entering the circular collecting cylinder 204 from the filter hole 205 is precipitated synchronously. The rotating shaft 104 will drive the auxiliary blade 206 to rotate to ensure that the salt in the circular collecting cylinder 204 will not agglomerate when precipitating. When the salt in the salt precipitation cylinder 101 is precipitated, the intelligent solenoid valve 208 on the discharge pipe 207 is opened, and the mother liquor in the salt precipitation cylinder 101 will be discharged into the nitrate precipitation cylinder 102 through the filter hole 205 and the discharge pipe 207. The filter hole 205 will retain the precipitated salt. Inside the salt precipitation cylinder 101, the drive motor 103 is reversed, and the rotating shaft 104 drives the round block 106 to rise, and the round block 106 drives the mixing plate 107 and the annular sealing plate 202 to rise. When the mixing plate 107 rises, it continues to scrape the inner wall of the salt precipitation cylinder 101, and the salt precipitated by the scaling on the inner wall of the salt precipitation cylinder 101 is scraped off to the bottom inner wall of the salt precipitation cylinder 101. The rise of the annular sealing plate 202 opens the discharge chute 201. At this time, the storage box 2 is connected to the discharge chute 201;

[0065] Since the compression spring 209 is in a compressed state when the telescopic slide 210 contacts the annular sealing plate 202, after the telescopic slide 210 leaves the annular sealing plate 202, the compression spring 209 will push the telescopic slide 210 out under the action of elastic force and contact the inner wall of the salt precipitation cylinder 101. When the rotating shaft 104 rotates, the telescopic slide 210 will be driven to rotate. The telescopic slide 210 and the rotating special-shaped plate 203 will generate centrifugal force during rotation. The centrifugal force will swing the salt on the inner wall of the bottom of the salt precipitation cylinder 101 toward the inner wall of the salt precipitation cylinder 101, and the salt will enter the storage box through the discharge chute 201. 2 for collection, and the salt in the circular collecting cylinder 204 will enter the nitration analysis cylinder 102 from the discharge pipe 207, that is, the collection of salt is completed, and the mother liquor entering the nitration analysis cylinder 102 will nitrate in the nitration analysis cylinder 102, and then the rotating shaft 104 is rotated forward to reset the mixing plate 107. Since the nitration analysis cylinder 102 and the salt analysis cylinder 101 have the same structural design, the operation in the salt analysis cylinder 101 and the operation in the nitration analysis cylinder 102 are synchronized under the action of the rotating shaft 104, and the salt and nitrate can be precipitated separately in the same way as the salt analysis step, thus eliminating the step of separating the salt and nitrate in the same container;

[0066] After precipitating nitrate, open the intelligent electromagnetic valve 208 at the input end of the circulation pump 3, start the circulation pump 3, and the circulation pump 3 will circulate the mother liquor of the precipitated nitrate into the salt precipitation cylinder 101 for salt precipitation again, and add an appropriate amount of unprecipitated mother liquor to precipitate salt together, repeat the precipitation operation, and when precipitating salt and nitrate, steam can be input into the heating annular box 303 on the salt precipitation cylinder 101 and the nitrate precipitation cylinder 102 respectively through the steam pump 304 and the steam box 302, and the temperature of the salt precipitation and nitrate precipitation can be controlled in conjunction with the temperature detector 305. Steam will be generated due to evaporation, and the steam will be discharged from the recovery pipe 306 into the rectangular recovery box 307. When the air pressure in the rectangular recovery box 307 is greater than the air pressure in the steam box 302, the steam in the rectangular recovery box 307 will push the T-shaped hollow plate 309 to slide into the steam box 302. At this time, the limit spring 308 is stretched and deformed. When the exhaust groove 310 on the T-shaped hollow plate 309 enters the steam box 302, the steam in the rectangular recovery box 307 will enter the steam box 302 from the exhaust groove 310, thereby realizing the recycling of steam and reducing heat waste.
