Description

Technical Field

[0001] The present invention relates to the technical field of liquid detection, in particular to a continuous automatic liquid separation system and a device thereof. Background Art

[0002] Generally, hydrochloric acid and the corresponding raw alcohol are used to prepare chloroalkanes. In the industrial preparation process, after the reaction of hydrochloric acid and the corresponding raw alcohol, liquid separation and stratification are required to separate the oil layer and the water phase. The substances in the oil layer are then purified by distillation to obtain the corresponding chloroalkanes. In industry, continuous and automatic liquid separation and stratification generally require the use of a settling tank, and a level gauge is required to monitor the position of the liquid interface in the settling tank. Magnetostrictive level gauges are generally used to monitor stratified liquids.

[0003] However, the float used by the magnetostrictive level gauge to detect the liquid level is prone to getting stuck during operation. The reason is generally that its own magnetism absorbs some iron-containing impurities in the liquid, causing blockage, or other dirt blocks the gap between the float and the detection rod, causing the float to be unable to move up and down with the liquid level, and thus unable to accurately monitor the height of the liquid level at this time.

[0004] Therefore, a continuous automatic liquid separation system and device are proposed. Summary of the Invention

[0005] The object of the present invention is to provide a continuous automatic liquid dispensing system and device thereof, which is provided with a floating cover and a placement groove, and detects whether there is a blockage in the gap between the corresponding float and the detection rod by checking whether the extrusion block 1 and the extrusion block 2 are separated for a long time. Then, a micro servo motor and a winding box cooperate with the silk thread and the snap ring. When the float is stuck, the micro servo motor drives the silk thread to be wound through the winding spring in the winding box, and then drives the float to move up and down through the snap ring. The blockage in the gap between the float and the detection rod is separated by the friction of the float movement, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A continuous automatic liquid dispensing system and device thereof, comprising:

[0008] A display unit, wherein the lower end of the display unit is connected to a detection rod, the detection rod is provided with a flange, and the detection rod is provided with two floats that can move with the liquid surface, and the two floats can be divided into an upper float and a lower float according to their positions;

[0009] Also includes:

[0010] A detection component, wherein each of the two floats is provided with a detection component for detecting whether the float is stuck;

[0011] A cleaning component is provided on the flange for cleaning blockages in the gap between the float and the detection rod, and the cleaning component is electrically connected to the detection component.

[0012] Preferably, the detection component includes placement grooves respectively opened on the top of the two floats, the shape of the two placement grooves is a circular groove with the detection rod as the axis, and the two placement grooves are symmetrically provided with matching grooves, the two matching grooves are provided with an extrusion block 1, and the two floats are provided with a floating cover adapted to the shape of the placement groove, the contact surface of the two floating covers with the corresponding placement grooves is inclined, the lower ends of the two floating covers are provided with an extrusion block 2 that cooperates with the corresponding extrusion block 1, each of the extrusion blocks 2 consists of a contact ball and a squeezing button, the interior of the two floating covers is hollow, and the interior of the floating cover of the lower float is provided with liquid with the same density as the upper liquid to be detected, a card slot is opened in the two placement grooves, and a card block that cooperates with the card slot is provided on the two floating covers, and a cleaning component for cleaning the gap between the two floats and the detection rods is provided on the flange, and each squeezing button is electrically connected to the cleaning component.

[0013] Each floating cover is embedded with a small battery, which serves as the power source for multiple squeeze buttons;

[0014] The magnetostrictive level gauge determines the float weight based on the "upper density" and "lower density" provided by the user when it leaves the factory. When the level gauge operates normally in the sedimentation tank, when the upper float floats on the upper liquid with lower density, half of the float will be immersed in the liquid, while the lower float will almost entirely float on the interface between the upper and lower liquids, completely immersed in the upper liquid. Due to the float's own magnetic absorption of impurities or debris generated by the reaction, it will enter the gap between the float and the detection rod, causing the float to get stuck. When the upper float is stuck, the sedimentation tank is opened. When the liquid in the container increases, the upper layer of liquid produced after the reaction will gradually submerge the upper float. Since the interior of the upper float cover is hollow and there is air, the upper float cover will move upward, causing the extrusion block 1 and the extrusion block 2 to separate, and the extrusion button in the extrusion block 2 to separate from the contact ball. The extrusion button is no longer squeezed. Under normal circumstances, there will be separation, but the separation time will not exceed 1 minute. When the separation time exceeds 1 minute, the extrusion button in the extrusion block 2 will give an electrical signal to the cleaning component, and the cleaning component will start to clean the gap between the float and the detection rod.

[0015] Similarly, when the lower float is stuck, as the amount of liquid flowing into the sedimentation tank increases, the lower layer of liquid produced after the reaction will gradually submerge the upper float. Because the lower float cover is equipped with a liquid with the same density as the upper layer of liquid to be detected, and its density is smaller than that of the lower layer of liquid, it will move upward, causing the squeezing block 1 and the squeezing block 2 in the lower float to separate, and the squeezing button in the squeezing block 2 to separate from the contact ball, and the squeezing button is no longer squeezed. When the separation time exceeds 1 minute, the squeezing button of the squeezing block 2 of the lower float cover will give an electrical signal to the cleaning component, and the cleaning component will start to clean the gap between the float and the detection rod.

[0016] There is a gap between the floating cover and the placement groove, and some external liquid will inevitably enter the gap. When the contact surface between the floating cover and the placement groove is straight, the dirt carried in the liquid will easily block it, causing the floating cover to be unable to move. The contact surface between the floating cover and the placement groove is set to be inclined to reduce the resistance of the dirt in the gap to the floating cover and the probability of the floating cover being blocked by the dirt. Since the distance between the float and the detection rod is clearly specified, generally about 1.4mm to 2mm, if the shape of the vertical square on the side of the float close to the detection rod is changed to an inclined shape, the gap between the float and the detection rod does not meet the regulations, and the float is more likely to get stuck due to the change in shape;

[0017] The card slot and the card block are arranged to cooperate so that when the floating cover moves upward, it is restricted by the card slot and the card block and cannot separate from the float. To ensure that after the blockage is cleared, the floating cover cooperates with the placement slot on the float to detect whether the float is subsequently blocked, which to a certain extent ensures the stability and accuracy of the magnetostrictive level meter detection.

[0018] Preferably, the cleaning component includes a micro servo motor threadedly connected to the flange, the output end of the micro servo motor is connected to a winding box, a coil spring is provided in the winding box, four silk threads are wound on the coil spring, the four silk threads are made of stainless steel, the four silk threads pass through the flange and extend downward along the detection rod, the four silk threads are grouped into two, each group of silk threads is connected to a clamping ring, the bottom of the two floats are provided with a concave cavity that cooperates with the clamping ring, and the two groups of silk threads are respectively connected to the concave cavities at the bottom of the two floats through the clamping rings.

[0019] When the button is squeezed to give the micro servo motor an electrical signal, the micro servo motor starts. The micro servo motor used is the HG-KR23BJ of the J4 series servo motor HG-KR series. The output end of the micro servo motor drives the coil spring in the reel box to reel in, and the coil spring drives the four silk threads to reel in and shrink. Then, the clasps on the two floats move upward along the detection rod driven by the corresponding silk threads. The concave cavity on the float cooperates with the clasp. Limited by the limitation of the concave cavity, the clasp drives the corresponding float to move upward, and the micro servo motor is set to start intermittently 3 times, each time for 5 seconds. Each time it starts, the two floats move upward along the detection rod through the four silk threads and the card block. When the micro servo motor stops, the two floats fall down under their own gravity. After moving back and forth, the blockage between the float and the detection rod is rubbed and then detached. Then, the blockage adhering to the detection rod will be scraped off by the clasp during the movement of the float, thereby achieving the cleaning effect.

[0020] Preferably, the top shape of each of the first extrusion blocks is hemispherical, and each of the second extrusion blocks is provided with a rubber ring for preventing external liquid from entering.

[0021] Although there is a floating cover to prevent external liquid from entering the placement tank, it is inevitable that liquid will enter through the gap between the floating cover and the placement tank, and then some fine dirt will remain in the matching tank and accumulate on the extrusion block 1. As a result, there will be a certain thickness of dirt between the contact ball and the extrusion block 1, resulting in reduced detection accuracy. The top shape of each extrusion block 1 is set to be hemispherical. Objects cannot be accumulated on the top of the hemispherical object, and thus too much dirt cannot be accumulated on the top of the extrusion block 1, thereby avoiding the above situation.

[0022] After the contact ball is squeezed by the squeezing block 1 and touches the squeezing button, a gap is formed between the contact ball and the outer shell of the squeezing block 2. After the liquid enters the matching groove, it is easy to enter through the gap. Each squeezing block 2 is provided with a rubber ring for preventing external liquid from entering the gap. The two ends of the rubber ring are respectively connected to the outer edge of the squeezing block 2 and the contact ball. Because the rubber ring is soft and has a certain degree of ductility, when the floating cover is driven to float up, the gravity of the contact ball itself drives the rubber ring to extend, and then the contact ball does not touch the squeezing button, thereby achieving the purpose of detection.

[0023] Preferably, the moving distance of each card block in the corresponding card slot is smaller than the height of the corresponding placement slot.

[0024] The moving distance of each card block in the corresponding card slot is set to be smaller than the height of the corresponding placement slot to prevent the bottom of the floating cover from detaching from the placement slot when the liquid increases and drives the floating cover to move upward after the float is stuck, causing excessive external liquid to enter the placement slot. Then, when the floating cover falls back, the liquid in the placement slot cannot be completely discharged, resulting in the squeeze block 1 and the squeeze block 2 not being able to contact normally, making it impossible for the contact ball to continue to apply pressure to the squeeze button, and the squeeze button to give an electrical signal to the micro servo motor, resulting in false detection of the start of the micro servo motor.

[0025] Preferably, the four silk threads are wrapped with a wire sheath near one end of the winding box, the two clamps are both ring-shaped, each of the clamps is provided with grooves on both sides, each of the grooves is provided with multiple rectangular springs, each of the rectangular springs is wrapped with a layer of rubber sleeve, and the multiple rectangular springs are commonly connected to an arc block, the shape of the arc block matches the concave cavity, and the detection rod is provided with a blocking block that matches the two floats.

[0026] The four silk threads are wrapped with a wire skin near one end of the winding box, and are dispersed near the upper float and divided into two groups, respectively connected to the corresponding clamping rings. Each of the blocking blocks is provided with four through-holes, and the four silk threads are passed through the through-holes respectively. The four through-holes are provided to fix the four silk threads to prevent the four silk threads from swinging in the liquid;

[0027] Each rectangular spring is wrapped with a rubber sleeve to prevent the liquid from entering the groove through the gap when the float is immersed in liquid, and then submerging the rectangular spring, which will cause wear and corrosion of the rectangular spring in the long run. The cross-section of the groove is trapezoidal. When the arc block is squeezed into the groove, the rubber sleeve will deform. The extra space in the groove can provide space for the deformed rubber sleeve to be placed, avoiding excessive squeezing of the rubber sleeve, which may cause damage to the rubber sleeve.

[0028] When the micro servo motor starts to clean the float continuously for times, if the squeeze button continues to give the micro servo motor an electrical signal, it means that the blockage between the float and the detection rod cannot be completely cleared by the motor driving the float up and down, and manual cleaning is required. The micro servo motor gives an electrical signal to the display unit, the display unit shows an error, and gives an electrical signal to the main control to remind the staff that the liquid level meter has a fault.

[0029] After the staff arrived at the magnetostrictive level gauge, they first removed the magnetostrictive level gauge, then grabbed the wire part wrapped with the wire skin with their hands and pulled it upward. The staff applied a large and rapid pulling force, which drove the float to move upward and squeezed against the blocking block. The force applied squeezed the rectangular spring, and the arc-shaped blocks on both sides of each retaining ring squeezed the rectangular spring into the groove under the squeezing force of the inner wall of the float, and then the pull ring moved upward in the gap between the float and the detection rod, scraping off the blockage in the gap, thereby quickly cleaning the gap between the float and the detection rod of the level gauge. There is no need to find other tools or equipment to clean it, and then the retaining ring is reset and the level gauge is installed back into the sedimentation tank.

[0030] Preferably, the contact surface between each arc-shaped block and the cavity is in the shape of an inclined surface.

[0031] The contact surface between each arc block and the concave cavity is set to be inclined. When the staff pulls the pull ring, the rectangular spring is squeezed under the restriction of the blocking block, and the arc block is inclined, which plays a guiding role, allowing the arc block to enter the groove faster and easier, thereby reducing the pulling force given by the staff when pulling the pull ring and the resistance of the blocking block, and the confrontation force between the arc block and the concave cavity, avoiding damage to the arc block during the process of the staff pulling the pull ring.

[0032] Preferably, each of the clamping rings is made of PTFE material.

[0033] A continuous automatic liquid dispensing system, the production process of which is as follows:

[0034] S1: Alcohol and hydrochloric acid are pumped into the reactor separately and mixed to obtain intermediate product 1;

[0035] S2: Continuous sedimentation; the intermediate product is cooled to 20-35°C and then enters the sedimentation tank A, where it is separated into layers to obtain an upper layer material A and a lower layer material A. The upper layer material A enters the crude product tank A, and the lower layer material A enters the acid water tank A. The upper layer material A entering the acid water tank A can precipitate a portion of the usable material A through static state, and the precipitated usable material A is returned to the sedimentation tank A, and the remaining impurity acid water is discharged to the treatment pool;

[0036] S3: continuous water washing; the upper layer material A, alkaline solution and water are put into the reactor in a certain proportion and mixed thoroughly to obtain the intermediate product 2;

[0037] S4: continuous sedimentation; the intermediate product 2 is placed in the sedimentation tank B for stratification to obtain the upper material B and the lower material B. The upper material B then enters the crude product tank B, and the lower material B enters the acid water tank B. Similarly, the lower material B in the acid water tank B will precipitate the usable material B after being still. The usable material B returns to the sedimentation tank B, and the other impurity acid water will be discharged to the treatment pool;

[0038] S5: Continuous drying; the upper material B is pumped into the intermediate tank, and the upper material B passes through the drying tank 1, drying tank 2 and drying tank 3 in sequence. The qualified dried product is the chloroalkane, which is passed into the storage tank, and the unqualified product returns to the intermediate tank for further drying.

[0039] Among them, the general process of the reaction in the sedimentation tank, acid water tank and crude product tank is used during stratification;

[0040] Sedimentation tank: The crude product enters the sedimentation tank first. As the liquid level in the tank continues to rise, the liquid level gauge reaches the upper limit of the design value and the interlock opens the acid water tank inlet valve; the interface meter reaches the lower limit of the design value and the interlock closes the acid water tank inlet valve; the interface meter reaches the upper limit of the design value and the interlock opens the crude product tank feed valve; the liquid level gauge reaches the lower limit of the design value and the interlock closes the crude product tank feed valve.

[0041] Acid water tank: When the liquid level meter reaches the upper limit of the design value, the acid water transfer pump is opened and the acid water is transferred out; when the interface meter reaches the lower limit of the design value, the acid water transfer pump is closed and the interface meter reaches the upper limit of the design value, the crude product transfer pump is opened and the crude product is transferred to the sedimentation tank for re-liquid separation; when the liquid level meter reaches the lower limit of the design value, the crude product transfer pump is closed and the interlock is turned off.

[0042] Crude product tank: When the liquid level gauge reaches the upper limit of the design value, the acid water transfer pump is turned on and the acid water at the bottom is discharged; when the interface gauge reaches the lower limit of the design value, the acid water transfer pump is turned off and the crude product transfer pump is turned on at the same time; when the liquid level gauge reaches the lower limit, the crude product transfer pump is turned off and the acid water transfer pump is turned on;

[0043] The liquid level gauges used in the sedimentation tank, acid water tank and crude product tank are all related to the above-mentioned devices, which are convenient for detecting the interface height of the liquid in the three tanks.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] 1. The continuous automatic liquid dispensing system and device described in the present invention are equipped with a floating cover and a placement groove. By checking whether the contact ball is separated from the squeeze button for a long time, it is possible to detect whether there is a blockage in the gap between the corresponding float and the detection rod, which causes the float to be unable to move with the liquid, thereby improving the accuracy of the liquid level meter.

[0046] 2. The continuous automatic liquid dispensing system and device described in the present invention cooperate with the silk thread and the retaining ring by setting a micro servo motor and a winding box. When the float is stuck, the micro servo motor drives the silk thread to be wound through the coil spring in the winding box, and then drives the float to move up and down through the retaining ring. The friction caused by the movement of the float causes the blockage in the gap between the float and the detection rod to be detached, thereby achieving the purpose of cleaning.

[0047] 3. The continuous automatic liquid separation system and device described in the present invention, when the float is driven up and down by the micro servo motor and the blockage in the gap between the float and the detection rod cannot be removed, the staff needs to remove the liquid level gauge. By arranging a pull ring and an arc block, the staff can use the pull ring to drive the clamping ring to move and quickly clean the liquid level gauge, avoiding the staff from looking for other tools to clean the blockage, thereby improving the efficiency of cleaning.

[0058] See also Figures 1 to 9 The present invention provides a continuous automatic liquid separation system and device thereof, and the technical solution is as follows:

[0059] During stratification, a sedimentation tank, an acid water tank, and a crude product tank are required, and level gauges are used in all three tanks to define the liquid level of the substances contained in the tanks. However, the magnetostrictive level gauge commonly used for stratification has the problem that the float 4 may get stuck. The reason is generally caused by the magnetically adsorbed substances or other impurities on the float 4 itself. To ensure the normal operation of the level gauge, it needs to be cleaned.

[0060] Example 1:

[0061] Condition: The blockage is relatively loose;

[0062] Working process: When the level gauge has no display or always displays the minimum, the greatest probability is that the float 4 is stuck. When the upper float 4 is stuck, the liquid introduced into the sedimentation tank continues to increase, and the upper layer of liquid produced after the reaction will gradually submerge the upper float 4. Because the upper float cover 404 is hollow and contains air, the upper float cover 404 will move upward, causing the squeezing block 1 403 and the squeezing block 2 405 to separate. Or, when the lower float 4 is stuck, the liquid introduced into the sedimentation tank increases, and the lower layer of liquid produced after the reaction will gradually submerge the upper float 4. Because the lower float cover 404 is provided with a liquid with the same density as the upper layer of liquid to be detected, and its density is smaller than that of the lower layer of liquid, it will move upward, thereby causing the squeezing block 1 403 and the squeezing block 2 405 in the lower float 4 to separate, and the squeezing button 4052 in the squeezing block 2 405 and the contact ball 405 1 is disengaged, and the squeezing button 4052 is no longer squeezed. When the disengagement time exceeds 1 minute, the squeezing button 4052 of the lower floating cover 404 will give an electrical signal to the micro servo motor 5. The output end of the micro servo motor 5 drives the coil spring in the coil box 6 to reel up, and the coil spring drives the four wires 7 to reel up and shrink. Then, the snap rings 8 on the two floats 4 move upward along the detection rod 2 under the drive of the corresponding wires 7. The concave cavity 9 on the float 4 cooperates with the snap ring 8. Limited by the restriction of the concave cavity 9, the snap ring 8 drives the corresponding float 4 to move upward. The micro servo motor 5 starts intermittently 3 times, each time for 5 seconds. When the micro servo motor 5 stops, the two floats 4 fall downward under their own gravity. Because the sticky blockage is relatively loose, after 3 back and forth movements, the blockage is basically rubbed out of the gap between the float 4 and the detection rod 2, and the liquid level meter resumes normal operation.

[0063] Example 2:

[0064] Conditions: The blockage is relatively tight;

[0065] Working process: When the level gauge has no display or always displays the minimum, the greatest probability is that the float 4 is stuck. When the upper float 4 is stuck, the liquid introduced into the sedimentation tank continues to increase, and the upper layer of liquid produced after the reaction will gradually submerge the upper float 4. Because the upper float cover 404 is hollow and has air inside, the upper float cover 404 will move upward, causing the extrusion block 1 403 and the extrusion block 2 405 to separate. Or when the lower float 4 is stuck, when the liquid introduced into the sedimentation tank increases, the lower layer of liquid produced after the reaction will gradually submerge the upper float 4. Because the lower float cover 404 is provided with a liquid with the same density as the upper layer of liquid to be detected, and its density is smaller than that of the lower layer of liquid, it will move upward, thereby causing the extrusion block 1 403 and the extrusion block 2 405 in the lower float 4 to separate. Disengagement, the squeezing button 4052 in the squeezing block 2 405 is disengaged from the contact ball 4051, and the squeezing button 4052 is no longer squeezed. When the disengagement time exceeds 1 minute, the squeezing button 4052 of the lower floating cover 404 will give an electrical signal to the micro servo motor 5. The output end of the micro servo motor 5 drives the coil spring in the coil box 6 to reel, and the coil spring drives the four wires 7 to reel and shrink. Then, the clasps 8 on the two floats 4 move upward along the detection rod 2 under the drive of the corresponding wires 7. The concave cavity 9 on the float 4 cooperates with the clasp 8. Limited by the restriction of the concave cavity 9, the clasp 8 drives the corresponding float 4 to move upward. The micro servo motor 5 starts intermittently 3 times, each time for 5 seconds. When the micro servo motor 5 stops, the two floats 4 fall downward under their own gravity.

[0066] Because the blockage is relatively compact, after the micro servo motor 5 starts to clean the float 4 three times in a row, the squeeze button 4052 continues to send an electrical signal to the micro servo motor 5, indicating that the blockage between the float 4 and the detection rod 2 cannot be completely cleared by the motor driving the float 4 up and down. The micro servo motor 5 sends an electrical signal to the display unit 1, the display unit 1 displays an error, and sends an electrical signal to the main control to remind the staff that the liquid level meter has a fault.

[0067] After the staff arrives at the magnetostrictive level gauge, they first remove the magnetostrictive level gauge, then grab the part of the wire 7 wrapped with the wire skin and pull it upward, driving the two snap rings 8 to move upward. Under the resistance of the blocking block 11 and the pulling force of the staff, as well as the restriction of the concave cavity 9 on the arc plate, the rectangular spring 802 is compressed, and the corresponding arc plate enters the groove 801 under the squeezing of the inner wall of the float 4. The staff grabs the wire 7 wrapped with the wire skin and drives the snap ring 8 to move along the detection rod 2 in the gap between the float 4 and the detection rod 2. The blockage in the gap is detached under the friction of the snap ring 8. Then the staff installs the new snap ring 8 and puts the level gauge back into the sedimentation tank.

8. A production process of a continuous automatic liquid dispensing system, characterized by: The continuous automatic liquid dispensing device according to any one of claims 1 to 7 comprises S1: pumping alcohol and hydrochloric acid into a reactor respectively and mixing them to obtain an intermediate product 1; S2: Continuous sedimentation; the intermediate product is cooled to 20-35°C and then enters the sedimentation tank A, where it is separated into layers to obtain an upper layer material A and a lower layer material A. The upper layer material A enters the crude product tank A, and the lower layer material A enters the acid water tank A. The lower layer material A entering the acid water tank A can precipitate a portion of the usable material A through static state, and the precipitated usable material A is returned to the sedimentation tank A, and the remaining impurity acid water is discharged to the treatment pool; S3: continuous water washing; the upper layer material A, alkaline solution and water are put into the reactor in a certain proportion and mixed thoroughly to obtain the intermediate product 2; S4: continuous sedimentation; the intermediate product 2 is placed in the sedimentation tank B for stratification to obtain the upper material B and the lower material B. The upper material B then enters the crude product tank B, and the lower material B enters the acid water tank B. Similarly, the lower material B in the acid water tank B will precipitate the usable material B after being still. The usable material B returns to the sedimentation tank B, and the other impurity acid water will be discharged to the treatment pool; S5: Continuous drying; the upper material B is pumped into the intermediate tank, and the upper material B passes through the drying tank 1, drying tank 2 and drying tank 3 in sequence. The qualified dried product is the chloroalkane, which is passed into the storage tank, and the unqualified product returns to the intermediate tank for further drying.
