Description

Technical Field

[0001] The invention relates to a potassium chloride crystal separation technology, in particular to a high-purity potassium chloride crystal separation device. Background Art

[0002] Potassium chloride crystal separation refers to the process of extracting potassium chloride crystals from a mixture. This separation is of great significance because potassium chloride is widely used in industrial production and laboratories. Separating pure potassium chloride can ensure product quality and the accuracy of experimental results.

[0003] In the prior art, in the process of filtering and purifying potassium chloride solution, when using column chromatography to purify potassium chloride solution, the potassium chloride solution is often directly filtered through a filter purification column, so that some recyclable substances in the potassium chloride solution are dispersed and adsorbed by different adsorption materials inside the filter purification column during the filtering process, which increases the difficulty of recycling the recyclable substances in the later stage, and the failure to recycle causes the waste of resources of the recyclable substances; when the filter purification column is used for a long time, the filtering effect of the substances inside the filter is gradually weakened due to the large amount of impurities, and the filtering speed is gradually slowed down. The staff often directly replaces the filter purification column as a whole, so that some of the substances that can still be used are wasted, and in order to speed up the filtering speed during the filtering process, the filtering speed is often accelerated by increasing the pressure, which is easy to cause the displacement of the substances used for filtering, resulting in the mutual mixing of the substances, and the filtering effect is affected after the substances are mixed;

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

A liquid guide pipe 211 is installed between two adjacent ones of the attapulgite purification column 11, the chelate resin purification column 12 and the activated carbon purification column 13. A suction pump 27 is installed at the middle position of the outer wall of the liquid guide pipe 211. The suction pump 27 can be installed on the support frame 28 through a supporting structure. Switch valves are installed on the outer walls of the drainage pipe 210, the liquid guide pipe 211 and the infusion pipe 212. The upper surface of the support frame 28 is rotatably connected to the solution total bin 21. The solution total bin A plurality of evenly distributed roller frames 23 are arranged on the outer side of the lower surface of the total solution bin 21, a lower bin 25 is integrally formed on the outer side of the lower surface of the total solution bin 21, a butt joint pipe 24 is installed at the outer wall of the lower bin 25 near the position of the infusion tube 212, a switch valve is also installed on the butt joint pipe 24, a gate is installed at the connection between the total solution bin 21 and the lower bin 25, a rotating sleeve is installed at the middle position of the upper surface of the total solution bin 21, a rotating shaft 22 is rotatably connected to the inner side of the rotating sleeve, a stirring shaft is installed on the outer side of the rotating shaft 22 corresponding to the inner part of the total solution bin 21, when the rotating shaft 22 rotates, the solution inside the total solution bin 21 is stirred and mixed by the stirring shaft to prevent the potassium chloride solution inside the total solution bin 21 from being static In the case of precipitation, a driving motor is installed at the position of the rotating shaft 22 corresponding to the upper surface of the supporting frame 28, a bevel gear 1 is installed at the output end of the driving motor, and a bevel gear 2 is installed at the position of the bevel gear 1 corresponding to the outer wall of the rotating shaft 22.

A telescopic groove is provided at the position of the outer wall of the rotating shaft 22 corresponding to the outer side of the solution total warehouse 21, and a limit block is installed on the inner side of the telescopic groove through an energized spring. A limit hole is provided at the position of the rotating sleeve corresponding to the limit block. The limit block moves its position through the control of the energized spring and can be inserted into the inner side of the limit hole to limit the rotating shaft 22, so that the rotating sleeve and the rotating shaft 22 rotate synchronously;

[0024] In the prior art, in the process of filtering and purifying potassium chloride solution, when the potassium chloride solution is purified by column chromatography, the potassium chloride solution is often directly filtered through the filtering purification column 1, so that part of the recyclable substances in the potassium chloride solution are dispersed and adsorbed by different adsorption materials inside the filtering purification column 1 during the filtering process, which increases the difficulty of recycling the recyclable substances in the later stage, and the failure to recycle causes a waste of resources of the recyclable substances;

[0025] In the process of filtering impurities of the potassium chloride solution in the order of the attapulgite purification column 11, the chelate resin purification column 12 and the activated carbon purification column 13, the attapulgite purification column 11 has a large specific surface area and a pore structure, and can effectively remove suspended solids and some organic matter. The chelate resin purification column 12 is suitable for removing specific metal ions in water, such as copper, lead, cadmium, etc. The activated carbon has a strong adsorption capacity. The activated carbon purification column 13 is used to remove organic matter, chlorine, odor and pigment in the solution. This sequence first removes suspended matter and some organic matter, then removes specific metal ions, and finally removes extensive organic matter and odor. After the large particles of suspended matter and organic matter are removed, the difficulty of filtering impurities of the potassium chloride solution by the subsequent chelate resin purification column 12 and the activated carbon purification column 13 can be effectively reduced.

[0026] In the process of filtering the potassium chloride solution in the order of the chelating resin purification column 12, the attapulgite purification column 11 and the activated carbon purification column 13, the chelating resin purification column 12 first removes the metal ions, the attapulgite purification column 11 removes the remaining suspended matter and some organic matter, and the activated carbon purification column 13 further removes the organic matter and odor. This order is suitable for the solution containing a higher concentration of metal ions, which are preferentially removed, so that when the chelating resin purification column 12 is backwashed later, the higher concentration of metal ions can be reasonably recycled;

[0027] In the process of filtering the potassium chloride solution in the order of the activated carbon purification column 13, the attapulgite purification column 11 and the chelating resin purification column 12, the activated carbon purification column 13 removes organic matter and chlorine, the attapulgite purification column 11 removes suspended matter, and the chelating resin purification column 12 removes metal ions. This order is suitable for the situation where the concentration of organic matter in the solution is high and needs to be removed first, and then the suspended matter and metal ions are removed;

[0028] Before the gate above the lower bin 25 of the solution contained in the total solution bin 21 is opened, the detector inside the total solution bin 21 can detect the concentrations of suspended solids, organic matter and metal ions in the solution. If the test result shows that the amount of suspended solids is large, plan one is adopted; if the test result shows that the amount of metal ions is large, plan two is adopted; if the test result shows that the amount of organic matter is large, plan three is adopted; the attapulgite purification column 11, the chelating resin purification column 12 and the activated carbon purification column 13 are arranged clockwise on the inner side of the support frame 28, and the position of the attapulgite purification column 11 is marked by the control system. During the rotation of the support frame 28, the position of the attapulgite purification column 11 is recorded at all times, and the driving motor rotates the total solution bin 21, keeping the rotation angle of each time at 120 degrees, so that when plan one is adopted, the control system can be directly used to control the total solution bin 21. The system transmits a signal to the device that supplies power to the energized spring, so that the energized spring pops up when the power is turned off, driving the limit block to pop out outward and insert it into the inner side of the limit hole on the rotating sleeve, so that when the driving motor drives the rotating shaft 22 to rotate, it can drive the solution total warehouse 21 connected to the rotating sleeve to rotate. The driving motor is a stepping motor. Through the setting of the program, the driving motor drives the solution total warehouse 21 to rotate 120 degrees and then stop rotating. After several rotations, the infusion tube 212 on the convex rod purification column 11 is docked with the docking tube 24, and the limit mechanism on the support frame 28 limits the position of the solution total warehouse 21. The control system transmits a signal to the device that supplies power to the energized spring and the limit mechanism again, so that the energized spring pops up when the power is turned off, driving the limit block to shrink toward the inner side of the telescopic groove, while the limit mechanism limits the position of the rotating solution total warehouse 21.

[0029] Embodiment 2:

[0030] See also Figure 3-4As shown, the impurity filtration purification column 1 is composed of an upper top cover 31, a lower top cover 34 and several connecting pipes 33. The upper top cover 31 is connected to the upper storage bin 26 through an inlet 37. A spiral connecting groove 39 is provided below the outer side walls of the upper top cover 31 and the connecting pipe 33. A spiral connecting groove 39 is also provided above the inner side walls of the connecting pipe 33 and the lower top cover 34. The upper top cover 31 and the connecting pipe 33 and the connecting pipe 33 and the lower top cover 34 are connected by threads. A guide block 38 is integrally formed below the inner side wall of the connecting pipe 33. The guide block 38 guides the falling material to the middle position of the connecting pipe 33, so that the material will not be preferentially accumulated at the position of the limiting slide groove 36. A limiting slide groove 36 is provided at the middle position of the inner side wall of the guide block 38. The limiting slide groove 36 is designed in an inclined shape. The support grid 32 is slidably connected at the position. When the support grid 32 slides from the inside of the limiting slide groove 36 from top to bottom, the fitting degree between the support grid 32 and the inner wall of the limiting slide groove 36 gradually increases due to the inclination of the limiting slide groove 36. A limiting ring is integrally formed at the upper end of the support grid 32. A fixed frame 310 is integrally formed on both sides of the inner wall of the guide block 38 near the bottom of the support grid 32. One end of the fixed frame 310 on one side of the inner wall of the guide block 38 is rotatably connected to a movable frame 35. The setting of the movable frame 35 enables the support grid 32 to be installed from the top of the connecting pipe 33 or from the bottom of the connecting pipe 33. A connecting buckle is installed at the position of the fixed frame 310 on the other side of the guide block 38 through a spring. A liquid level gauge is arranged inside the lower top cover 34, and a pressure gauge is arranged on the upper surface of the movable frame 35.

[0031] In the prior art, when the impurity filtering purification column 1 is used for a long time, the filtering effect of the impurity filtering material inside is gradually weakened due to the large amount of impurities, and the filtering speed is gradually slowed down. The staff often directly replaces the entire impurity filtering purification column 1, so that some of the impurities that can still be used are wasted. In addition, in order to speed up the impurity filtering speed during the impurity filtering process, the filtering speed is often accelerated by increasing the pressure. The increase in pressure can easily cause the displacement of the impurity filtering material, resulting in the mutual mixing of the various substances, which affects the filtering effect after the impurities are mixed.

[0032] The upper cover 31 and the connecting pipe 33 are connected to the connecting pipe 33 and the lower cover 34 by threads. The user can select the number of spliced ​​connecting pipes 33 according to his own needs. A support grid 32 is added inside the connecting pipe 33 for support, so that the impurities used for filtering between the connecting pipes 33 are not easily displaced and mixed with each other under the action of external pressure. The pressure gauge on the movable frame 35 and the liquid level gauge inside the lower cover 34 can respectively record the pressure value of the supporting grid 32 on the movable frame 35 and the liquid level value in the lower cover 34. The control system records the liquid level value and transmits the detected liquid level value to the control system. The control system calculates the liquid level value and the detection time inside the lower top cover 34 to obtain the liquid flow rate data of the filter purification column 1, and draws a binary coordinate system diagram according to the liquid flow rate and time changes. While increasing the pressure to speed up the filtering speed, the control system processes the pressure data. When the pressure value detected by the pressure gauge on the inside of any connecting pipe 33 exceeds the set pressure value, the pressurization operation is stopped to prevent the support grid 32 from being broken due to continued pressurization, resulting in the mutual mixing of filtered impurities and affecting the filtering effect. The specific process is as follows: collect the real-time pressure feedback from the corresponding pressure gauge on the inner side of the connecting pipe 33 at each preset frequency, sort all the real-time pressures according to the order of the time of collection, compare the size between the two adjacent real-time pressures, if the later real-time pressure is greater than the previous real-time pressure, calculate the difference between the two adjacent implementation pressures to obtain the boost value, sum all the boost values ​​to obtain the total boost value, divide all the total boost values ​​by the total number of all real-time pressures to obtain the boost ratio and mark it as FS1; obtain the last sorted real-time pressure and mark it as FS2, normalize the boost ratio FS1 and the real-time pressure FS2 and take the value between the two, substitute it into the formula YL=FS1×η1+FS2×η2 to obtain the pressure value YL; where η1 and η2 are the weight factors corresponding to the boost ratio FS1 and the real-time pressure FS2 respectively; when the pressure value exceeds the set pressure value, the control system generates the corresponding stop boost signal and stops the boost operation. By analyzing the boost ratio of the real-time pressure and combining it with the real-time pressure, it is possible to avoid the pressure rising too fast, failing to respond in time and stopping the boost operation.

[0033] When the present invention is in use, before the gate above the lower bin 25 of the solution contained in the solution main bin 21 is opened, the detector inside the solution main bin 21 can detect the concentrations of suspended solids, organic matter and metal ions in the solution. If the detection result shows that the amount of suspended solids is large, then scheme 1 is adopted, that is, the attapulgite purification column 11, the chelate resin purification column 12 and the activated carbon purification column 13 are sequentially used to filter the potassium chloride solution. Since the attapulgite purification column 11 has a large specific surface area and a pore structure, the suspended solids and part of the organic matter can be effectively removed. The chelate resin purification column 12 is suitable for removing specific metal ions in water, such as copper, lead, cadmium, etc. The activated carbon has a strong adsorption capacity. The activated carbon purification column 13 is used to remove organic matter, chlorine, odor and pigment in the solution. This sequence first removes suspended matter and part of the organic matter, then removes specific metal ions, and finally removes a wide range of organic matter and odor. After the large particles of suspended matter and organic matter are removed, the difficulty of filtering the potassium chloride solution by the subsequent chelate resin purification column 12 and the activated carbon purification column 13 can be effectively reduced. If the test result shows that the amount of metal ions is large, then scheme two is adopted, that is, the order of the chelating resin purification column 12, the attapulgite purification column 11 and the activated carbon purification column 13 is used to filter the potassium chloride solution, the chelating resin purification column 12 first removes the metal ions, the attapulgite purification column 11 removes the remaining suspended matter and some organic matter, and the activated carbon purification column 13 further removes the organic matter and odor. This order is suitable for the solution containing a high concentration of metal ions, and they are removed first, so that when the chelating resin purification column 12 is backwashed later, the metal ions with a high concentration can be reasonably recycled; if the test result shows that the amount of organic matter is large, then scheme three is adopted, that is, the order of the activated carbon purification column 13, the attapulgite purification column 11 and the chelating resin purification column 12 is used to filter the potassium chloride solution, the activated carbon purification column 13 removes organic matter and chlorine, the attapulgite purification column 11 removes suspended matter, and the chelating resin purification column 12 removes metal ions. This order is suitable for the situation where the organic concentration in the solution is high and needs to be removed first, and then the suspended matter and metal ions are removed;The attapulgite purification column 11, the chelate resin purification column 12 and the activated carbon purification column 13 are arranged clockwise on the inner side of the support frame 28. According to the position mark of the attapulgite purification column 11 by the control system, the position of the attapulgite purification column 11 is recorded at all times during the rotation of the support frame 28. The driving motor rotates the solution main chamber 21, and the rotation angle is kept at 120 degrees each time. When the scheme 1 is adopted, the attapulgite purification column 11 and the chelate resin purification column 12 and the liquid guide tube 211 between the chelate resin purification column 12 and the activated carbon purification column 13 are connected, and the solution flows in from the upper storage bin 26 at the upper end of the attapulgite purification column 11, reaches the upper storage bin 26 at the upper end of the chelate resin purification column 12 through the lower storage bin 29 at the lower end of the attapulgite purification column 11, and then reaches the upper storage bin 26 at the upper end of the activated carbon purification column 13 from the lower storage bin 29 at the lower end of the chelate resin purification column 12, and finally flows out from the activated carbon purification column 1 3 flows out from the lower storage bin 29 at the lower end, and directly transmits a signal to the device for supplying power to the energized spring through the control system, so that the energized spring is powered off and pops up, driving the limit block to pop out outward, and inserts into the inner side of the limit hole on the rotating sleeve, so that when the driving motor drives the rotating shaft 22 to rotate, it can drive the total solution bin 21 connected to the rotating sleeve to rotate. The driving motor is a stepping motor. Through the setting of the program, the driving motor drives the total solution bin 21 to rotate 120 degrees and then stops rotating. After multiple rotations, the infusion tube 212 on the attapulgite purification column 11 is docked with the docking tube 24, and the limit mechanism on the support frame 28 limits the position of the total solution bin 21. The control system transmits a signal to the device for supplying power to the energized spring and the limit mechanism again, so that the energized spring is powered off and pops up, driving the limit block to shrink to the inner side of the telescopic groove, while the limit mechanism limits the position of the rotating total solution bin 21.When the second scheme is adopted, the chelating resin purification column 12 is connected to the attapulgite purification column 11 and the liquid conduit 211 between the attapulgite purification column 11 and the activated carbon purification column 13, and the solution flows in from the upper storage bin 26 at the upper end of the chelating resin purification column 12, reaches the upper storage bin 26 at the upper end of the attapulgite purification column 11 through the lower storage bin 29 at the lower end of the chelating resin purification column 12, and then reaches the upper storage bin 26 at the upper end of the activated carbon purification column 13 from the lower storage bin 29 at the lower end of the attapulgite purification column 11, and finally flows out from the lower storage bin 29 at the lower end of the activated carbon purification column 13, and directly transmits a signal to the device for supplying power to the energized spring through the control system, so that the energized spring is de-energized and pops up, driving the limit block to pop out outward, and inserts into the inner side of the limit hole on the rotating sleeve, so that the driving motor drives the rotating shaft When the support frame 22 is rotated, the solution main chamber 21 connected to the rotating sleeve can be driven to rotate. The driving motor is a stepping motor. Through the setting of the program, the driving motor drives the solution main chamber 21 to rotate 120 degrees and then stops rotating. After multiple rotations, the infusion tube 212 on the attapulgite purification column 11 is aligned with the docking tube 24, and the support frame 22 is rotated at an angle of 120 degrees again to dock the infusion tube 212 of the chelating resin purification column 12 with the docking tube 24. The limiting mechanism on the supporting frame 28 limits the position of the solution main chamber 21. The control system transmits a signal to the device for supplying power to the energized spring and the limiting mechanism again, so that the energized spring is powered off and pops up to drive the limiting block to shrink to the inside of the telescopic groove. At the same time, the limiting mechanism limits the position of the rotating solution main chamber 21. When scheme three is adopted, the liquid guide tube 211 between the activated carbon purification column 13 and the attapulgite purification column 11 and the attapulgite purification column 11 and the chelating resin purification column 12 is connected, and the solution flows into the upper storage bin 26 at the upper end of the activated carbon purification column 13, reaches the upper storage bin 26 at the upper end of the attapulgite purification column 11 through the lower storage bin 29 at the lower end of the activated carbon purification column 13, and then reaches the upper storage bin 26 at the upper end of the chelating resin purification column 12 from the lower storage bin 29 at the lower end of the attapulgite purification column 11, and finally flows out from the lower storage bin 29 at the lower end of the chelating resin purification column 12, and directly transmits a signal to the device for supplying electricity to the energized spring through the control system, so that the energized spring is powered off and pops up to drive the limit block to pop out outward, and is inserted into the inner side of the limit hole on the rotating sleeve, so that the driving motor drives the rotating shaft When 22 rotates, it can drive the solution total chamber 21 connected to the rotating sleeve to rotate. The driving motor is a stepping motor. Through the setting of the program, the driving motor drives the solution total chamber 21 to rotate 120 degrees and then stops rotating. After multiple rotations, the infusion tube 212 on the attapulgite purification column 11 is aligned with the docking tube 24, and the infusion tube 212 of the activated carbon purification column 13 is docked with the docking tube 24. The limiting mechanism on the support frame 28 limits the position of the solution total chamber 21. The control system transmits a signal to the device and the limiting mechanism for supplying power to the energized spring again, so that the energized spring is powered off and pops up to drive the limiting block to shrink to the inside of the telescopic groove. At the same time, the limiting mechanism limits the position of the rotating solution total chamber 21.

[0034] The upper cover 31 and the connecting pipe 33 are connected to the connecting pipe 33 and the lower cover 34 by threads. The user can select the number of spliced ​​connecting pipes 33 according to his own needs. A support grid 32 is added inside the connecting pipe 33 for support, so that the impurities used for filtering between the connecting pipes 33 are not easily displaced and mixed with each other under the action of external pressure. The pressure gauge on the movable frame 35 and the liquid level gauge inside the lower cover 34 can respectively measure the pressure value of the supporting grid 32 on the movable frame 35 and the liquid level value in the lower cover 34. The data is recorded and transmitted to the control system. The control system calculates the liquid level value and the detection time inside the lower top cover 34 to obtain the liquid flow rate data of the filter purification column 1, and draws a binary coordinate system diagram according to the liquid flow rate and time changes. While increasing the pressure to speed up the filtering speed, the control system processes the pressure data. When the pressure value detected by the pressure gauge on the inside of any connecting pipe 33 exceeds the set pressure value, the pressurization operation is stopped to prevent continued pressurization from causing the support frame 32 to rupture, resulting in the mutual mixing of filtered impurities and affecting the filtering effect.
