Description

Technical Field

[0001] This invention relates to the field of purification equipment technology, specifically to a gradient sweating purification device for phase change energy storage materials. Background Technology

[0002] With energy issues becoming increasingly prominent, phase change energy storage technology, as a key means to improve energy efficiency, has received widespread attention. The performance of phase change energy storage materials directly affects the energy storage effect, and purity is one of the important factors determining material performance.

[0003] Currently, common purification methods for phase change energy storage materials include distillation, recrystallization, and adsorption. Among these, distillation utilizes the difference in boiling points between the phase change energy storage material and impurities to achieve separation. The material is heated above its boiling point, causing the lower-boiling-point components to vaporize first. The vapor is then collected by condensation, thus achieving purification. This method is suitable for separating substances with significant differences in boiling points. However, for high-boiling-point or heat-sensitive phase change energy storage materials, high-temperature distillation may lead to material decomposition or changes in performance, limiting its application range. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a gradient sweating purification device for phase change energy storage materials, which solves the problem that high-temperature distillation may lead to material decomposition or performance changes during the purification of high-boiling-point or thermosensitive phase change energy storage materials, thus limiting their application range.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gradient perspiration purification device for phase change energy storage materials, comprising a device housing, a feeding hopper and a driving device disposed on the upper side of the device housing, an outer cylinder disposed on the inner top wall of the device housing, a heating device disposed on the outer wall of the outer cylinder, an inner cylinder disposed inside the outer cylinder, the lower side of the feeding hopper being located above the inner cylinder, a plurality of micro-through holes being opened on the lower side of the inner cylinder, a discharge pipe being fixedly disposed on the lower side of the outer cylinder, a waste box being disposed below the discharge pipe, a storage box being disposed below the waste box, a blade and a connecting rod being fixedly disposed at the output end of the driving device, the blade being rotatably connected to the inside of the inner cylinder, the lower end of the connecting rod being located above the storage box, a liquid receiving pipe being fixedly disposed on the outer wall of the lower end of the connecting rod, and one end of the liquid receiving pipe being located directly below the discharge pipe.

[0006] By adopting the above technical solution, the phase change energy storage material is put into the inner cylinder through the feed hopper. The heating device is activated to heat the outer cylinder to a preset value and maintain the preset temperature. Through thermal radiation, the internal temperature of the inner cylinder rises and reaches the preset value, thereby melting the low melting point impurities in the phase change energy storage material in the inner cylinder. These impurities drip into the outer cylinder through micro-holes and then flow out of the discharge pipe and are collected in the waste box. The heating device continues to raise the temperature, causing the phase change energy storage material to melt. Through the cooperation of the device shell, connecting rod and liquid receiving pipe, the molten phase change energy storage material enters the storage box and cools down. Meanwhile, the high melting point impurities can be further melted by heating and collected in the waste box. This completes the purification of the phase change energy storage material through gradient evaporation, thus solving the problem that high-temperature distillation may cause material decomposition or performance changes when purifying high-boiling-point or heat-sensitive phase change energy storage materials, which limits their application range.

[0008] Preferably, the outer wall of the device housing is provided with an ultrasonic vibration device, the outer wall of the output end of the ultrasonic vibration device passes through the side wall of the device housing and the outer cylinder, and the output end of the ultrasonic vibration device is fixedly disposed on the outer wall of the inner cylinder. The outer wall of the output end of the ultrasonic vibration device is provided with a rubber sleeve, and one side of the rubber sleeve is fixedly connected to the inner wall of the outer cylinder.

[0009] Preferably, a plurality of liquid guiding needles are fixedly connected to the lower side of the inner cylinder. The liquid guiding needles are disposed inside the micro-through holes, the size of which is between - micrometers.

[0010] Preferably, a conical groove is formed on the inner bottom wall of the outer cylinder, and the discharge pipe is located at the bottom of the conical groove.

[0011] Preferably, a support plate is fixedly connected to the inner wall of the device housing, the lower end of the connecting rod passes through the upper and lower sides of the support plate, and the lower outer wall of the connecting rod is rotatably connected to the support plate. A ratchet is provided on the lower outer wall of the connecting rod, and a pawl is engaged with the tooth end of the ratchet. The lower side of the pawl is provided on the upper side of the support plate.

[0012] Preferably, a cleaning port is provided on one side of the device housing, and a cleaning box is provided on one side of the device housing. The cleaning box and the cleaning port are connected. The end of the liquid receiving tube away from the connecting rod is located inside the cleaning box, and the outer wall of the liquid receiving tube and the inner wall of the cleaning port are pre-set with a gap.

[0013] Preferably, the storage box is slidably connected to the inner bottom wall of the device housing, the inner wall of the device housing is fixedly connected to the second support plate, the lower side of the waste box is slidably connected to the upper side of the second support plate, and the other side of the device housing is equipped with a first discharge plate and a second discharge plate, which are used for picking up and putting in the storage box and the waste box, respectively.

[0014] Preferably, a shock-absorbing ring is fixedly connected to the upper side of the inner cylinder, and the upper side of the shock-absorbing ring is fixedly connected to the inner top wall of the device housing.

[0015] Preferably, a controller is provided on the outer wall of the device housing, and the controller is electrically connected to the ultrasonic vibration device, the motor, and the heating device.

[0016] Working principle: The phase change energy storage material is fed into the inner cylinder through the feeding hopper. The heating device is activated by the controller to heat the material to the preset temperature and maintain the temperature in the inner cylinder at the preset value. The controller also drives the motor output to rotate gear three, which in turn drives gear one to rotate, causing the paddle to rotate and stir the phase change energy storage material in the inner cylinder, accelerating the melting of its low-melting-point impurities. At the same time, the controller activates the ultrasonic vibration device, causing the inner cylinder to vibrate at high frequency. The vibration of the inner cylinder is reduced by the action of the damping ring. The high-frequency vibration of the inner cylinder causes the molten liquid and unmelted solid inside to separate quickly. The liquid is then discharged to the waste box below through the micro-through holes and the liquid guide needles installed inside, thus completing the removal of low-melting-point impurities from the phase change energy storage material.

[0017] The controller continues heating the heating device, keeping the temperature within the melting range of the phase change energy storage material. Simultaneously, the motor drives the one-way gear two to rotate, which in turn rotates the liquid receiving pipe to the bottom of the discharge pipe, collecting the molten phase change energy storage material and thus completing the purification of the phase change energy storage material. The discharge plate controls the heating device to further increase the temperature, causing all the remaining high-melting-point impurities in the inner cylinder to melt. At the same time, the liquid receiving pipe is no longer below the discharge pipe, and the molten high-melting-point impurities are collected by the waste box. This completes the gradient evaporation purification of the phase change energy storage material, thus solving the problem that high-temperature distillation may cause material decomposition or performance changes during the purification of high-boiling-point or heat-sensitive phase change energy storage materials, which limits their application range.

[0018] This invention provides a gradient perspiration purification device for phase change energy storage materials. It has the following beneficial effects:

[0019] 1. This invention provides support for the feed hopper through the device shell, and maintains the inner cylinder at a preset temperature by gradient adjustment of the heating temperature of the outer cylinder through the heating device. This causes the low-melting-point impurities, the phase change energy storage material itself, and the high-melting-point impurities in the phase change energy storage material in the inner cylinder to melt sequentially and flow out through the micro-through holes and the discharge pipe. At the same time, the drive device drives the paddle to rotate, improving the melting efficiency of the material in the inner cylinder. Through the cooperation of the connecting rod and the liquid receiving pipe, the waste box and the storage box alternately collect impurities and purified phase change energy storage material. This solves the problem that high-temperature distillation may cause material decomposition or performance changes during the purification of high-boiling-point or heat-sensitive phase change energy storage materials, which limits their application range.

[0020] 2. This invention provides support for the motor through the outer casing, and through the forward and reverse rotation of the motor output end, and through the design of unidirectional rotation of one-way gear one and one-way gear two, combined with the mutual cooperation of pawl and ratchet, the driving device realizes the function of driving the blade and connecting rod.

[0021] 3. The present invention uses a controller to provide support for the ultrasonic vibration device through the device housing, and drives the outer cylinder through the output end of the ultrasonic vibration device, thereby causing the outer cylinder to vibrate at high frequency. Combined with the cooperation of the micro-through hole and the liquid guiding needle, the solid-liquid separation efficiency in the inner cylinder is improved. Attached Figure Description

[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 4 Appendix Figure 6 and attached Figure 8 This invention provides a gradient perspiration purification device for phase change energy storage materials, including a device housing 2. A feeding hopper 3 and a driving device 4 are arranged on the upper side of the device housing 2. An outer cylinder 17 is arranged on the inner top wall of the device housing 2. A heating device 16 is arranged on the outer wall of the outer cylinder 17. An inner cylinder 23 is arranged inside the outer cylinder 17. The lower side of the feeding hopper 3 is located above the inner cylinder 23. Several micro-through holes 26 are opened on the lower side of the inner cylinder 23. A discharge pipe 15 is fixedly arranged on the lower side of the outer cylinder 17. A waste box 14 is arranged below the discharge pipe 15. A storage box 13 is arranged below the waste box 14. A blade 24 and a connecting rod 18 are fixedly arranged at the output end of the driving device 4. The blade 24 is rotatably connected to the inside of the inner cylinder 23. The lower end of the connecting rod 18 is located above the storage box 13. A liquid receiving pipe 9 is fixedly arranged on the outer wall of the lower end of the connecting rod 18. One end of the liquid receiving pipe 9 is located directly below the discharge pipe 15.

[0034] In this embodiment, Figure 4 The heating device 16, with its orientation defined by front, back, left, and right, includes: a main heating element, employing a high-power infrared heating plate for rapid heating; an auxiliary heating element, using resistance wire heating, evenly distributed along the height of the outer cylinder 17, which can be precisely adjusted by an intelligent control system; and an intelligent control system, including a central processing unit, temperature sensors, control circuits, and software, for precise adjustment of the heating temperature of the heating device 16. The heating device 16 allows for the adjustment and control of the heating temperature of the phase change energy storage material, which is a current technology.

[0035] Specifically, the phase change energy storage material is placed into the inner cylinder 23 through the feed hopper 3. The heating device 16 is activated. Through the contact between the heating device 16 and the outer cylinder 17, the heat generated by the heating device 16 is conducted to the outer cylinder 17, so that the temperature inside the outer cylinder 17 is maintained within a preset range. The temperature inside the inner cylinder 23 is also maintained within a preset range through thermal radiation, thereby melting the low melting point impurities in the phase change energy storage material. At the same time, the driving device 4 drives the paddle 24 to rotate inside the inner cylinder 23, stirring the phase change energy storage material and accelerating the melting process. The molten low melting point impurities fall into the outer cylinder 17 through the micro-through hole 26 opened on the lower side of the inner cylinder 23, and continue to move downward to the waste box 14 through the discharge pipe 15 set at the bottom of the outer cylinder 17, thereby achieving the removal of low melting point impurities in the phase change energy storage material.

[0036] After a certain period of time, the low-melting-point impurities are completely removed. At this point, driven by the drive device 4, the connecting rod 18 is rotated, causing the end of the receiving pipe 9 away from the connecting rod 18 to rotate directly below the discharge pipe 15. The heating device 16 increases the heating temperature, maintaining the internal temperature of the inner cylinder 23 within the melting range of the phase change energy storage material. The molten phase change energy storage material falls into the receiving pipe 9 through the micro-through hole 26 and the discharge pipe 15. The lower ends of the receiving pipe 9 and the connecting rod 18 are hollow structures and are connected. Guided by the receiving pipe 9, the molten phase change energy storage material enters the lower end of the connecting rod 18. The material then falls into the storage box 13, completing the collection of the phase change energy storage material. After all the phase change energy storage material has melted, the remaining material in the inner cylinder 23 is high-melting-point impurities. Then, driven by the drive device 4, the liquid receiving pipe 9 is no longer located below the discharge pipe 15, and the heating device 16 further increases the heating temperature, causing all the solid material in the inner cylinder 23 to melt and fall into the waste box 14, thus completing the removal of high-melting-point impurities. This solves the problem that high-temperature distillation may cause material decomposition or performance changes during the purification of high-boiling-point or heat-sensitive phase change energy storage materials, which limits their application range.

[0037] See appendix Figure 3 Appendix Figure 4 and attached Figure 9The drive device 4 includes a housing 40, which is disposed on the upper side of the device housing 2. A motor 42 is disposed on the inner wall of the housing 40. A gear 3 44 is fixedly disposed on the output end of the motor 42. The teeth of the gear 3 44 are meshed with a one-way gear 1 41 and a one-way gear 2 43. The lower side of the one-way gear 1 41 is fixedly connected to the upper side of the blade 24. The lower side of the one-way gear 2 43 is fixedly connected to the upper side of the connecting rod 18. The upper outer walls of the blade 24 and the connecting rod 18 are rotatably connected to the upper side of the device housing 2. The lower side of the blade 24 is rotatably connected to the inner bottom wall of the inner cylinder 23.

[0038] Specifically, refer to Figure 9 One-way gear 41 and one-way gear 43 are unidirectional rotating gears consisting of a ratchet and pawl assembly. The housing 2 provides support for the outer casing 40, which in turn supports the motor 42. Driven by the output of the motor 42, gear 44 rotates. The meshing of the teeth of gear 44 with those of one-way gear 41 drives one-way gear 41 to rotate. At this time, the teeth of one-way gear 43 and the portion connecting one-way gear 43 to the connecting rod 18 rotate relative to each other, thus preventing the connecting rod 18 from rotating. This is achieved through a fixed connection between the lower side of one-way gear 41 and the upper side of the blade 24. The blade 24 is rotatably connected to the upper side of the device housing 2 and the bottom wall of the inner cylinder 23, thereby causing the blade 24 to rotate inside the inner cylinder 23 and agitate the phase change energy storage material in the inner cylinder 23. When the liquid receiving pipe 9 needs to rotate, the reverse rotation of the output end of the motor 42 drives the one-way gear 43 to rotate. At this time, the one-way gear 43 drives the connecting rod 18 to rotate, thereby causing the liquid receiving pipe 9 to rotate directly below the discharge pipe 15. At this time, the tooth end of the one-way gear 41 and the connection part between the one-way gear 41 and the blade 24 rotate relative to each other, thereby realizing the driving function of the drive device 4.

[0039] See appendix Figure 4 and attached Figure 6 An ultrasonic vibration device 1 is provided on the outer wall of the device housing 2. The outer wall of the output end of the ultrasonic vibration device 1 passes through the side wall of the device housing 2 and the outer cylinder 17. The output end of the ultrasonic vibration device 1 is fixedly installed on the outer wall of the inner cylinder 23. A rubber sleeve 21 is provided on the outer wall of the output end of the ultrasonic vibration device 1. One side of the rubber sleeve 21 is fixedly connected to the inner wall of the outer cylinder 17.

[0040] Specifically, the device housing 2 provides support for the ultrasonic vibration device 1. The outer wall of the output end of the ultrasonic vibration device 1 and the part passing through the device housing 2 and the outer cylinder 17 are pre-spaced so that the output end of the ultrasonic vibration device 1 will not affect the outer cylinder 17 and the device housing 2. The rubber sleeve 21 provides a sealed isolation between the output end of the ultrasonic vibration device 1 and the outer cylinder 17, which helps to improve the control of the internal temperature range of the outer cylinder 17 and prevent heat loss. The output end of the ultrasonic vibration device 1 drives the inner cylinder 23 to vibrate at high frequency, which separates the phase change energy storage material into solid and liquid, thereby improving the purification efficiency of the phase change energy storage material.

[0041] See appendix Figure 8 Multiple liquid guiding needles 27 are fixedly connected to the lower side of the inner cylinder 23. The liquid guiding needles 27 are located inside the micro-through holes 26, and the size of the micro-through holes 26 is between 50 and 100 micrometers.

[0042] Specifically, by designing the micro-holes 26 with a size between 50 and 100 micrometers, the liquid in the inner cylinder 23 can flow out through the micro-holes 26, while effectively isolating the solid matter inside. Furthermore, by setting the liquid guide needles 27 and combining them with the ultrasonic vibration device 1, the outflow rate of the liquid inside the inner cylinder 23 is increased, thereby improving the purification efficiency of the phase change energy storage material.

[0043] See appendix Figure 7 A conical groove 25 is provided on the inner bottom wall of the outer cylinder 17, and the discharge pipe 15 is located at the bottom of the conical groove 25.

[0044] Specifically, when the liquid in the inner cylinder 23 falls into the outer cylinder 17, the design of the conical groove 25 causes the liquid in the outer cylinder 17 to gather at the bottom of the conical groove 25 under the action of gravity, and then flow out through the discharge pipe 15, thereby improving the efficiency of the liquid flow in the outer cylinder 17.

[0045] See appendix Figure 4 and attached Figure 5 A support plate 11 is fixedly connected to the inner wall of the device housing 2. The lower end of the connecting rod 18 passes through the upper and lower sides of the support plate 11, and the lower outer wall of the connecting rod 18 is rotatably connected to the support plate 11. A ratchet 20 is provided on the lower outer wall of the connecting rod 18. A pawl 19 is engaged with the tooth end of the ratchet 20. The lower side of the pawl 19 is provided on the upper side of the support plate 11.

[0046] Specifically, the housing 2 provides support for the support plate 11, and the support plate 11 and the connecting rod 18 are rotatably connected, thus providing support for the lower end of the connecting rod 18. When the tooth end of the one-way gear 43 and its connection part with the connecting rod 18 rotate relative to each other, the pawl 19 and the ratchet 20 interfere with each other, limiting the ratchet 20 so that it does not rotate, and thus the connecting rod 18 does not rotate. When the motor 42 reverses and drives the tooth end of the one-way gear 43 and its connection part with the connecting rod 18 to rotate in the same direction, the pawl 19 and the ratchet 20 do not interfere with each other, and the pawl head of the pawl 19 slides over the tooth end of the ratchet 20, thus causing the connecting rod 18 to rotate. This achieves the limitation of the connecting rod 18 and improves the stability of the rotation of the connecting rod 18.

[0047] See appendix Figure 2 and attached Figure 4 A cleaning port 10 is provided on one side of the device housing 2, and a cleaning box 8 is provided on one side of the device housing 2. The cleaning box 8 and the cleaning port 10 are connected. The end of the liquid receiving pipe 9 away from the connecting rod 18 is located inside the cleaning box 8, and the outer wall of the liquid receiving pipe 9 and the inner wall of the cleaning port 10 are pre-set with a gap.

[0048] Specifically, by rotating the connecting rod 18, the liquid receiving tube 9 is driven to rotate horizontally around the connecting rod 18. When the liquid receiving tube 9 rotates to be close to the cleaning box 8, the end of the liquid receiving tube 9 away from the connecting rod 18 can rotate into the interior of the cleaning box 8. During the rotation of the liquid receiving tube 9, it does not interfere with the cleaning port 10. When it is necessary to clean the liquid receiving tube 9, the liquid receiving tube 9 can be rotated into the interior of the cleaning box 8 and the cleaning box 8 can be removed. At this time, the end of the liquid receiving tube 9 away from the connecting rod 18 is located outside the device housing 2, so the liquid receiving tube 9 can be rinsed, wiped and other cleaning work can be performed, thereby helping to realize the function of cleaning the liquid receiving tube 9.

[0049] See appendix Figure 1 Appendix Figure 3 and attached Figure 4 The storage box 13 is slidably connected to the inner bottom wall of the device housing 2. The inner wall of the device housing 2 is fixedly connected to the support plate 12. The lower side of the waste box 14 is slidably connected to the upper side of the support plate 12. The other side of the device housing 2 is equipped with a discharge plate 6 and a discharge plate 7, which are used for taking out and putting in the storage box 13 and the waste box 14, respectively.

[0050] Specifically, the device housing 2 provides support for the support plate 12 and the storage box 13, and in turn, provides support for the waste box 14. When the storage box 13 needs to be picked up or put down, the discharge plate 7 can be opened, and the waste box 14 can be picked up or put down through the horizontal sliding connection between the waste box 14 and the support plate 12. When the storage box 13 needs to be picked up or put down, the discharge plate 6 can be opened, and the storage box 13 can be driven through the horizontal sliding connection between the lower side of the storage box 13 and the inner bottom wall of the device housing 2, thereby realizing the function of picking up and putting down the storage box 13 and the waste box 14.

[0051] See appendix Figure 4 and attached Figure 6 A shock-absorbing ring 22 is fixedly connected to the upper side of the inner cylinder 23, and the upper side of the shock-absorbing ring 22 is fixedly connected to the inner top wall of the device housing 2.

[0052] Specifically, the damping ring 22 can be made of rubber, which reduces the transmission of vibration through its own deformation. When the output end of the ultrasonic vibration device 1 drives the inner cylinder 23 to vibrate at high frequency, the damping ring 22 absorbs the vibration of the upper end of the inner cylinder 23 to a certain extent, thus avoiding the impact of the vibration of the inner cylinder 23 on the device housing 2 and the outer cylinder 17, thereby realizing the function of damping the inner cylinder 23.

[0053] See appendix Figure 3 and attached Figure 4 The outer wall of the device housing 2 is equipped with a controller 5, which is electrically connected to the ultrasonic vibration device 1, the motor 42, and the heating device 16.

[0054] Specifically, the controller 5 can be a PLC programmable controller, which is supported by the device housing 2. The controller 5 controls the start and heating function of the heating device 16, the start of the ultrasonic vibration device 1 to accelerate the separation of solid and liquid in the inner cylinder 23, and the drive of the motor 42 to drive the blades 24 to stir the phase change energy storage material in the inner cylinder 23 and adjust the rotation of the connecting rod 18, thereby helping to improve the purification efficiency of the phase change energy storage material.
