Description

Technical Field

[0001] This invention relates to the field of molecular sieve dewatering device technology, specifically to a molecular sieve dewatering device. Background Technology

[0002] Because molecular sieves have excellent dehydration properties, they are widely used, for example, in the dehydration of gases and the dehydration of monomeric alkanes.

[0003] In existing methods of dehydrating gases, the gas is typically passed through a molecular sieve dehydration cylinder with multiple sets of molecular sieves. The water absorption property of the molecular sieves is used to remove the water from the gas. However, the molecular sieves will eventually become saturated during the absorption process. If they are not replaced regularly, this will greatly affect production costs and significantly reduce the quality of the discharged gas.

[0004] Currently, when replacing molecular sieves, the molecular sieve dewatering cylinder is opened directly, the molecular sieve is poured out, and then a new molecular sieve is filled into the molecular sieve dewatering cylinder. Subsequent molecular sieve dewatering cylinders are replaced in the same way. The whole process is time-consuming and labor-intensive, greatly increasing labor and time costs, thereby reducing overall work efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a molecular sieve dewatering device to solve the technical problem in the prior art where, when replacing a molecular sieve, the molecular sieve dewatering cylinder is directly opened, the molecular sieve is poured out, and a new molecular sieve is filled into the molecular sieve dewatering cylinder. Subsequent molecular sieve dewatering cylinders are replaced in the same way. The whole process is time-consuming and labor-intensive, which greatly increases labor and time costs and reduces overall work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a molecular sieve dewatering device, comprising a reduction tank and multiple sets of molecular sieve dewatering cylinders. A first transition box and a second transition box are symmetrically arranged on the outer side of the reduction tank. Multiple sets of molecular sieve dewatering cylinders are evenly and sequentially arranged on the top of both the first and second transition boxes, and a connecting pipe connects adjacent sets of molecular sieve dewatering cylinders. A guide cylinder penetrates the bottom of the reduction tank, and an output pipe connects to the bottom of the guide cylinder. A second discharge pipe connects the output pipe to both the first and second transition boxes. The top of the reduction tank rotates... The device is connected to a rotating shaft, and an elliptical feeding box is movably fitted to the top of the rotating shaft. The elliptical feeding box is connected to multiple sets of molecular sieve dewatering cylinders by a first feeding pipe. A self-priming component is installed between the elliptical feeding box and the bottom of the outer side of the reduction tank. A driving component is installed on the top of the elliptical feeding box. The output end of the driving component is provided with a first stirring component connected to the rotating shaft. A guide component connected to the rotating shaft is movably installed inside the reduction tank, and a second stirring component that cooperates with the bottom of the bottom of the reduction tank is provided at the bottom edge of the guide component. A heating aeration component is installed at one end of the output pipe.

[0007] By employing the above technical solution, multiple sets of molecular sieve dewatering cylinders are used to absorb water from the gas. During this process, a first and second transition box, along with a control system, periodically guides the molecular sieves from the dewatering cylinders into the corresponding first and second transition boxes, finally entering the output pipe. At this point, a heated aeration assembly delivers high-temperature dry gas into the output pipe, blowing the molecular sieves into the guide cylinder. During this process, the blown-up molecular sieves are subjected to a high-temperature shock, causing the water inside the molecular sieves to vaporize, thus dewatering the molecular sieves. This process is further enhanced by a rotating base and multiple sets of guide cylinders. The agitator spreads the molecular sieves blown up by the agitator towards the inner wall of the reduction tank, preventing them from returning along their original path. Due to gravity, the molecular sieves fall to the bottom of the reduction tank. Then, with the help of the self-priming component, the dried molecular sieves are drawn from the bottom of the reduction tank into the elliptical feeding box. During this process, the drive component rotates the first stirring component, which facilitates the sequential and even introduction of the dried molecular sieves into the molecular sieve dewatering cylinder. This cycle of drying the molecular sieves eliminates the need for manual emptying and periodic replacement. The reusable molecular sieves significantly reduce labor and operating costs, thus improving overall work efficiency.

[0009] By adopting the above technical solution, the molecular sieve in the reduction tank is easily raised to a higher level using the suction pump for circulation, and in conjunction with the conveying pipe, the work can be completed.

[0010] The present invention is further configured such that the driving component includes a motor, and the motor is installed at the center of the top of the elliptical feeding box.

[0011] By adopting the above technical solution, the motor facilitates the driving of the first stirring component, the guiding component, and the second stirring component, thereby completing the work.

[0013] By adopting the above technical solution, the connecting shaft, baffle, extension plate, spring, and cavity are used to make it easy for the extension plate to be adapted to the inner wall of the elliptical feeding box, so as to complete the work.

[0015] By adopting the above technical solution, the molecular sieve is diffused outwards by utilizing the action of the rotating seat and the guide plate, so as to complete the work.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of the present invention will now be described.

[0036] A molecular sieve dehydration device, such as Figure 1-6As shown, the device includes a reduction tank 1 and multiple sets of molecular sieve dehydration cylinders 4. The multiple sets of molecular sieve dehydration cylinders 4 absorb water from the gas. A first transition box 2 and a second transition box 3 are symmetrically arranged on the outside of the reduction tank 1. Multiple sets of molecular sieve dehydration cylinders 4 are evenly arranged sequentially on the top of both the first transition box 2 and the second transition box 3, and a connecting pipe 6 connects adjacent sets of molecular sieve dehydration cylinders 4. A guide cylinder 20 penetrates the bottom of the inside of the reduction tank 1, and an output pipe 12 connects to the bottom of the guide cylinder 20. A second discharge pipe connects the output pipe 12 to both the first transition box 2 and the second transition box 3. Pipe 13, in conjunction with the control system, periodically guides the molecular sieve from the molecular sieve dewatering cylinder 4 into the corresponding first transition box 2 and second transition box 3, and finally into the output pipe 12. One end of the output pipe 12 is equipped with a heating aeration component. This component delivers high-temperature dry gas into the output pipe 12, blowing the molecular sieve into the guide cylinder 20. During this process, the blown-up molecular sieve is subjected to a high-temperature shock, causing the moisture inside the molecular sieve to vaporize, thus dewatering the molecular sieve. Furthermore, the rotating seat 28 and multiple sets of guide plates 29 further guide the blown-up molecular sieve... The molecular sieve diffuses towards the inner wall of the reduction tank 1, preventing it from returning along its original path. Due to gravity, the molecular sieve falls to the bottom of the reduction tank 1. A rotating shaft 9 is rotatably connected to the top of the reduction tank 1. An elliptical feeding box 7 is movably fitted to the top of the rotating shaft 9. The elliptical feeding box 7 is connected to the first feeding pipe 5 through multiple sets of molecular sieve dewatering cylinders 4. A self-priming component is installed between the elliptical feeding box 7 and the bottom outer side of the reduction tank 1. With the action of the self-priming component, the dried molecular sieve is drawn from the bottom of the reduction tank 1 into the elliptical feeding box 7. A driving component is installed on the top of the elliptical feeding box 7. The output end is equipped with a first stirring component connected to the rotating shaft 9. The inside of the reduction tank 1 is equipped with a guide component connected to the rotating shaft 9. The bottom edge of the guide component is equipped with a second stirring component that cooperates with the bottom of the reduction tank 1. Together with the drive component, the first stirring component will be driven to rotate, so that the dried molecular sieve can be introduced into the molecular sieve dewatering cylinder 4 in sequence and evenly. In this way, the molecular sieve is dried in a cycle. There is no need for manual dumping or periodic automatic replacement. The molecular sieve is recycled, which greatly reduces labor costs and operating costs, thus improving the overall work efficiency.

[0037] Please see Figure 1 The self-priming assembly includes a suction pump 10 and a conveying pipe 11. The suction pump 10 is installed on the top of the elliptical feeding box 7, and the conveying pipe 11 is connected between the output end of the suction pump 10 and the bottom of the outer side of the reduction tank 1. The suction pump 10 is used to raise the molecular sieve in the reduction tank 1 to a higher level for circulation. In conjunction with the conveying pipe 11, the work is completed.

[0038] Please see Figure 1 and Figure 3The drive assembly includes a motor 8. The motor 8 is installed at the top center of the elliptical feeding box 7. The motor 8 is used to drive the first stirring assembly, the guide assembly and the second stirring assembly to complete the work.

[0039] Please see Figure 3 The first stirring assembly includes a connecting shaft 22, a baffle 23, an extension plate 25, a spring 24, and a cavity 32. The connecting shaft 22 is located in the middle of the interior of the elliptical feeding box 7. Baffles 23 are evenly arranged on the outer side of the connecting shaft 22. The extension plate 25 is slidably connected to the interior of the baffle 23 through the spring 24. The interior of the baffle 23 has a cavity 32 that cooperates with the extension plate 25. By utilizing the functions of the connecting shaft 22, the baffle 23, the extension plate 25, the spring 24, and the cavity 32, the extension plate 25 can be adapted to the inner wall of the elliptical feeding box 7 to facilitate the operation.

[0040] Please see Figure 4 The guiding assembly includes a rotating seat 28 and a guide plate 29. The bottom of the rotating shaft 9 is connected to the rotating seat 28, which extends into the inside of the reduction tank 1. Multiple sets of guide plates 29 are evenly arranged at the bottom of the rotating seat 28. The rotating seat 28 and the guide plate 29 facilitate the diffusion of the molecular sieve to the outside to complete the work.

[0041] Please see Figure 5 The second stirring component includes a connecting column 30 and a scraper 31. The bottom of the rotating seat 28 is provided with a connecting column 30, and the bottom of the connecting column 30 is provided with a scraper 31 that cooperates with the bottom of the inside of the reduction tank 1. By utilizing the function of the connecting column 30 and the scraper 31, blockage is avoided during material feeding.

[0042] Please see Figure 1 The bottom of the first transition box 2 and the second transition box 3 are symmetrically provided with support legs 17, and the bottom of the support legs 17 is provided with a base 18 to ensure the stability of the equipment. The first transition box 2, the second transition box 3 and the reduction tank 1 are all connected by a connecting seat 19 to ensure the stability of the first transition box 2 and the second transition box 3.

[0043] Please see Figure 3 The heated aeration assembly includes a heated aeration pump 14. The heated aeration pump 14, which is connected to the output pipe 12, is installed on the top of the base 18. The heated aeration pump 14 is used to heat the gas before releasing it, thereby completing the work.

[0044] Please see Figure 3 and Figure 5A first solenoid valve 21 is installed between the conveying pipe 11 and the reduction tank 1, and a third solenoid valve 35 is installed between the first feeding pipe 5 and the elliptical feeding box 7. A second solenoid valve 33 is installed between the molecular sieve dewatering cylinder 4 and the first transition box 2 and the second transition box 3. By utilizing the functions of the first solenoid valve 21, the second solenoid valve 33 and the third solenoid valve 35, it is convenient to control the flow of the equipment during operation.

[0045] Please see Figure 1 and Figure 5 An air inlet pipe 15 is provided on the outside of one set of molecular sieve dehydration cylinders 4, and an air outlet pipe 16 is provided on the outside of another set of molecular sieve dehydration cylinders 4. An exhaust pipe 27 is connected to the outside of the reduction tank 1. A first filter plate 26 is provided between the exhaust pipe 27 and the reduction tank 1. A second filter plate 34 is provided at the top of the output pipe 12. The air inlet pipe 15 and the exhaust pipe 16 facilitate the entry and exit of gas. The first filter plate 26 and the second filter plate 34 prevent the molecular sieve from being discharged.

[0046] The working principle of this invention is as follows: When in use, the gas enters the molecular sieve dehydration cylinder 4 through the inlet pipe 15 and is finally discharged through the outlet pipe 16, thereby using the molecular sieve to absorb the water in the gas. The above structure is formed by connecting multiple sets of molecular sieve dehydration cylinders 4 and connecting pipes 6 in sequence, so that the gas passes through multiple sets of molecular sieve dehydration cylinders 4 for filtration and absorption, thereby improving the dehydration effect of the gas.

[0047] After a period of time, the molecular sieve will reach saturation. This process utilizes a humidity sensor to detect the humidity inside the last set of molecular sieve dewatering cylinders 4. When the humidity reaches a certain value, the second solenoid valve 33 is activated, causing the molecular sieve inside the corresponding molecular sieve dewatering cylinder 4 to be guided by gravity into the corresponding first transition box 2 and second transition box 3. Finally, the corresponding second discharge pipe 13 drops into the output pipe 12 and places it on the second filter plate 34. Then, the heating aeration assembly is activated, that is, the heating aeration pump 14 is activated, causing it to input high-temperature dry gas into the output pipe 12 and blow up the molecular sieve. Under the high-temperature dry gas, the inside of the molecular sieve... The water evaporates rapidly. When the molecular sieve passes the guide cylinder 20, evaporation is complete, and it continues to rise. Simultaneously, the drive assembly, i.e., the motor 8, is activated, causing the connecting shaft 22, rotating shaft 9, and rotating seat 28 to rotate coaxially. This, in turn, drives multiple sets of guide cylinders 20 to rotate, so that after contacting the molecular sieve, the water moves along the guide cylinder 20 under the action of centrifugal force towards the inner wall of the reduction tank 1. Finally, under the action of gravity, it falls to the bottom of the reduction tank 1. At this time, because the scraper 31 is connected to the rotating seat 28 through the connecting column 30, the scraper 31 rotates, stirring to prevent blockage. This keeps the molecular sieve in motion, thereby accelerating water evaporation. Once all the molecular sieves inside the molecular sieve dewatering cylinder 4 have been removed, the second solenoid valve 33 is immediately closed, while the first solenoid valve 21 is opened. Finally, the self-priming assembly is activated, i.e., the suction pump 10 is started, causing the molecular sieves inside the reduction tank 1 to enter the elliptical feeding box 7 along the conveying pipe 11. Driven by the rotating connecting shaft 22, the shaft drives multiple sets of baffles 23 and the extension plate 25 to rotate. Since the extension plate 25 can move freely within the baffle 23 using springs 24, one side of the extension plate 25 can engage with the inner wall of the elliptical feeding box 7, allowing the molecular sieves to rotate and be stirred inside the elliptical feeding box 7, further increasing the moisture content inside the molecular sieves. During evaporation, when most of the molecular sieves have entered the elliptical feeding box 7, the first solenoid valve 21 is closed and the third solenoid valve 35 is opened, allowing the molecular sieves inside the elliptical feeding box 7 to fall along the first feeding pipe 5 into the corresponding molecular sieve dewatering cylinder 4 until it is completely filled. Then, the third solenoid valve 35 is closed. During this process, the rotating extension plate 25 and the baffle 23 facilitate the entry of the molecular sieves into the first feeding pipe 5 for better material feeding. This cycle is used to dry the molecular sieves, eliminating the need for manual emptying and periodic automatic replacement. The cyclic use of molecular sieves greatly reduces labor and operating costs, thus improving overall work efficiency.
