Technical Field

[0001] The utility model relates to the technical field of cryogenic air separation, in particular to a cryogenic air separation purification device. Background Technique

[0002] Cryogenic air separation is a kind of air separation technology, also known as the deep freezing air separation method. That is, air is frozen and liquefied, and then the liquefied gas is distilled and separated according to the principle of different boiling points between liquefied gases. Before separating the gas, it is necessary to purify the air to remove water vapor and impurities in the air.

[0003] An air purifier with the application number 202322787883.2. It includes: a claw-shaped pipeline, a filter cylinder, a separation cylinder, a clamping device, a pushing device, a mounting table and a base; the claw-shaped pipeline is used to connect the filter cylinder and the separation cylinder; the clamping device is arranged beside the filter cylinder, and the clamping device includes a clamping jaw and a driving member, and the driving member is used to drive the clamping jaw to clamp and release the filter cylinder; the pushing device is arranged beside the filter cylinder, and the pushing device is used to tilt the filter cylinder to facilitate the removal of the filter cylinder; the mounting table is fixedly connected to the base, and the mounting table is used to mount the driving member. The beneficial effect of this application is that it provides an air purifier in which the filter cylinder is clamped by the clamping jaw. When the filter cylinder needs to be replaced, the clamping jaw can be opened and the pushing device can be started to tilt the filter cylinder so as to facilitate the removal of the filter cylinder.

[0004] This technical solution requires a set of limiting structures and a set of actuating elements for each filtering structure. First, the pipeline is relatively complex and cumbersome during maintenance; second, the procurement cost is relatively high; third, the energy consumption during operation is relatively large, resulting in a relatively high operating cost. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a cryogenic air separation purification device to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cryogenic air separation purification device includes a device main body. A fixed seat is connected below the interior of the device main body, and a placement seat is connected below one side of the fixed seat. A retaining frame is fixed on one side of the top of the placement seat. A limiting plate penetrates through one side of the fixed seat, and a tension spring is connected to one side of the limiting plate. A second strong magnetic plate is fixed on the other side of the limiting plate. A motor is installed in the middle of the top of the device main body, and an installation shaft is connected to the output end of the motor. A first strong magnetic plate is fixed on the outer surface of the installation shaft.

[0007] By adopting the above technical solution, when a filter element needs to be replaced, the output end of the motor drives the installation shaft to rotate so that the first strong magnetic plate corresponds to the filter element that needs to be replaced. At this time, the first strong magnetic plate attracts the second strong magnetic plate above the filter element through magnetic attraction, so that the limit plate on the top of this filter element is retracted into the fixed seat to end the limit of the filter element. After that, the filter element can be removed, and then the new filter element is placed in the placement seat to complete the replacement. At this time, the placement seat and the retaining frame cooperate to avoid horizontal displacement of the filter element. After the replacement is completed, the motor drives the installation shaft to rotate to make the first strong magnetic plate away from the second strong magnetic plate, so that the tension spring drives the limit plate to extend and resist the top of the filter element, thereby preventing the filter element from falling off upward, and the limit is completed.

[0008] Furthermore, the cross section of the limiting plate is in a "T" shape, and the limiting plate is slidably connected to the fixing seat.

[0009] By adopting the above technical solution, the first strong magnetic plate attracts the second strong magnetic plate above the filter element through magnetic attraction, so that the limiting plate on the top of this filter element is retracted into the fixed seat to end the limitation of the filter element, and the limiting plate stretches the tension spring connected to it, and then the staff can pull the filter element out of the device body.

[0010] Furthermore, the installation shaft is rotatably connected to the fixing seat, and the cross-section of the fixing seat is heptagonal.

[0011] By adopting the above technical solution, after the motor is started, the output end drives the installation shaft to rotate, and the rotation of the installation shaft drives the first magnetic plate to rotate. The cross-section of the fixed seat is heptagonal, six of which can be used with six filter elements, and the remaining one surface is convenient for the first strong magnetic plate to correspond, avoiding that there is always one filter element that is not limited.

[0012] Furthermore, the first strong magnetic plate and the second strong magnetic plate are in the same horizontal plane.

[0013] By adopting the above technical solution, after the motor is started, the output end drives the installation shaft to rotate, and the rotation of the installation shaft drives the first magnetic plate to rotate, so that the first strong magnetic plate corresponds to the filter element that needs to be replaced. At this time, the first strong magnetic plate attracts the second strong magnetic plate above the filter element through magnetic attraction.

[0014] Furthermore, an air inlet is connected to the outer surface of the device body, an air outlet pipe is passed through the top of the device body, and a valve is installed at the bottom of the air outlet pipe, a filter element is connected to the top of the placement seat, and a hose is connected between the filter element and the valve, and an inspection door is connected to the top of the device body.

[0015] By adopting the above technical solution, compressed air enters the main body of the device through the air inlet, and then the compressed air is filtered through the filter element to remove impurities in the compressed air. Then the compressed air passes through the hose and the damper in turn into the outlet pipe, and then is sent to the next step through the outlet pipe.

[0016] Furthermore, the inspection door corresponds to the filter element, and the inspection door is threadedly connected to the device body.

[0017] By adopting the above technical solution, when a filter element needs to be replaced, the staff shuts down the cryogenic system and stops the gas supply. Then the staff removes the inspection door and reaches into the main body of the device to close the valve and separate the hose from the filter element to facilitate the replacement of the filter element.

[0018] Furthermore, the limit plate abuts against the top of the filter element, and the retaining frame abuts against one side of the filter element.

[0019] By adopting the above technical solution, the tension spring contracts and drives the limit plate to extend and press against the top of the filter element, thereby preventing the filter element from falling off upwards, thereby completing the limit.

[0020] Furthermore, the filter element is detachably connected to the placement seat, and one end of the hose is detachably connected to the filter element.

[0021] By adopting the above technical solution, the staff closes the valve and separates the hose from the filter element, and then the staff pulls the filter element out of the device body.

[0022] Furthermore, the inspection door, filter element, hose, valve, limit plate, second strong magnetic plate, tension spring, baffle and placement seat are arranged in six groups, and the six groups of inspection doors, filter element, hose, valve, limit plate, second strong magnetic plate, tension spring, baffle and placement seat are distributed in a fan-shaped array.

[0023] By adopting the above technical solution, the number of filter elements is increased to increase the filtration area, and the number of disassembly structures is correspondingly increased to facilitate replacement of the filter elements.

[0024] Furthermore, two protrusions are provided on one side of the top of the limiting plate, and the two protrusions on one side of the top of the limiting plate are in contact with the fixing seat.

[0025] By adopting the above technical solution, the two protrusions will abut against the fixing seat when the limiting plate is retracted into the fixing seat, thereby preventing the limiting plate from being displaced too much and causing the tension spring to be overstretched.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is provided with a motor, a first strong magnetic plate, a limit plate, a second strong magnetic plate, a tension spring, a stop frame and a placement seat. When a filter element needs to be replaced, the output end of the motor drives the mounting shaft to rotate so that the first strong magnetic plate corresponds to the filter element that needs to be replaced. At this time, the first strong magnetic plate attracts the second strong magnetic plate above the filter element through magnetic attraction, so that the limit plate on the top of this filter element is retracted into the fixed seat to end the limitation of the filter element. Thereafter, the filter element can be disassembled, and then a new filter element is placed in the placement seat to complete the replacement. At this time, the placement seat and the stop frame cooperate to avoid horizontal displacement of the filter element. After the replacement is completed, the motor drives the mounting shaft to rotate so that the first strong magnetic plate is away from the second strong magnetic plate, so that the tension spring drives the limit plate to extend and press against the top of this filter element, thereby preventing the filter element from falling off upwards, and thus completing the limitation. A single actuator can assist in completing the disassembly of multiple filter elements, and the structure is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1:

[0036] A cryogenic air separation purification device, such as Figures 1-4As shown in the figure, it includes a device main body 1. A fixing seat 16 is connected below the interior of the device main body 1. The cross-section of the fixing seat 16 is a heptagon, and six of its faces can be used in combination with six filter elements 5, while the remaining one face is convenient for the first strong magnetic plate 10 to correspond to, avoiding that there is always one filter element 5 not being limited; a placing seat 15 is connected below one side of the fixing seat 16. The filter element 5 is detachably connected to the placing seat 15. A blocking frame 14 is fixed on one side of the top of the placing seat 15. The blocking frame 14 abuts against one side of the filter element 5. The new filter element 5 is placed into the placing seat 15 to complete the replacement. At this time, the cooperation of the placing seat 15 and the blocking frame 14 prevents the filter element 5 from horizontally displacing; a limiting plate 11 penetrates through one side of the fixing seat 16. The cross-section of the limiting plate 11 is in a "T" shape. The limiting plate 11 is slidably connected to the fixing seat 16. The limiting plate 11 abuts against the top of the filter element 5. A tension spring 13 is connected to one side of the limiting plate 11. The contraction of the tension spring 13 drives the limiting plate 11 to extend out and abut against the top of this filter element 5, thereby preventing the filter element 5 from falling off upward; a second strong magnetic plate 12 is fixed on the other side of the limiting plate 11. A motor 8 is installed in the middle of the top of the device main body 1. The output end of the motor 8 is connected with a mounting shaft 9. The mounting shaft 9 is rotatably connected to the fixing seat 16. A first strong magnetic plate 10 is fixed on the outer surface of the mounting shaft 9. The first strong magnetic plate 10 and the second strong magnetic plate 12 are in the same horizontal plane. After the motor 8 is started, the output end drives the mounting shaft 9 to rotate. The rotation of the mounting shaft 9 drives the first magnetic plate to rotate, so that the first strong magnetic plate 10 corresponds to the filter element 5 that needs to be replaced. At this time, the first strong magnetic plate 10 attracts the second strong magnetic plate 12 above this filter element 5 through magnetic attraction, so that the limiting plate 11 at the top of this filter element 5 retracts into the fixing seat 16 to end the limitation of the filter element 5.

[0037] Refer to Figures 1-4 , in the above embodiment, an air inlet 2 is connected to the outer surface of the device main body 1. An air outlet pipe 3 penetrates through the top of the device main body 1. A valve 7 is installed at the bottom end of the air outlet pipe 3. A filter element 5 is connected to the top of the placing seat 15. A hose 6 is connected between the filter element 5 and the valve 7. Compressed air enters the interior of the device main body 1 through the air inlet 2. Then, the compressed air passes through the filter element 5 to filter out impurities in the compressed air. Then, the compressed air sequentially passes through the hose 6 and the air damper and enters the air outlet pipe 3, and then is sent to the next process through the air outlet pipe 3; one end of the hose 6 is detachably connected to the filter element 5. A maintenance door 4 is connected to the top of the device main body 1. The maintenance door 4 corresponds to the filter element 5. The maintenance door 4 is threadedly connected to the device main body 1. The staff removes the maintenance door 4 and reaches into the device main body 1 to close the valve 7 and separate the hose 6 from the filter element 5; six groups of maintenance doors 4, filter elements 5, hoses 6, valves 7, limiting plates 11, second strong magnetic plates 12, tension springs 13, blocking frames 14 and placing seats 15 are provided. The six groups of maintenance doors 4, filter elements 5, hoses 6, valves 7, limiting plates 11, second strong magnetic plates 12, tension springs 13, blocking frames 14 and placing seats 15 are all distributed in a fan-shaped array, and the filtration area is increased by increasing the quantity.

[0038] Embodiment Two:

[0039] On the basis of the above-mentioned first embodiment, in order to prevent the excessive displacement of the limit plate 11 from causing the tension spring 13 to be broken, the following settings are now made.

[0040] Refer to Figure 4 , in the above-mentioned embodiment, two protrusions are provided on one side of the top of the limit plate 11. The two protrusions on one side of the top of the limit plate 11 are in contact with the fixed seat 16. When the limit plate 11 retracts into the fixed seat 16, these two protrusions will abut against the fixed seat 16, thereby preventing the excessive displacement of the limit plate 11 from causing excessive stretching of the tension spring 13.

[0041] The implementation principle of the present utility model is as follows: First, compressed air enters the interior of the device main body 1 through the air inlet 2. After that, the compressed air is filtered by the filter element 5 to remove impurities in the compressed air. Then, the compressed air sequentially passes through the hose 6 and the air damper and enters the air outlet pipe 3, and is then sent into the next process through the air outlet pipe 3;

[0042] When it is necessary to replace a certain filter element 5, the staff closes the cryogenic system to stop gas transmission. Then, the staff removes the maintenance door 4 and reaches into the device main body 1 to close the valve 7 and separate the hose 6 from the filter element 5. Then, the staff starts the motor 8. After the motor 8 starts, the output end drives the installation shaft 9 to rotate. The rotation of the installation shaft 9 drives the first magnetic plate to rotate, so that the first strong magnetic plate 10 corresponds to the filter element 5 to be replaced. At this time, the first strong magnetic plate 10 attracts the second strong magnetic plate 12 above this filter element 5 through magnetic attraction, so that the limit plate 11 at the top of this filter element 5 retracts into the fixed seat 16 to end the limitation of the filter element 5, and the limit plate 11 stretches the tension spring 13 connected thereto. Then, the staff can pull out this filter element 5 from the device main body 1;

[0043] The staff places a new filter element 5 into the placement seat 15 to complete the replacement. At this time, the cooperation between the placement seat 15 and the blocking frame 14 prevents the horizontal displacement of the filter element 5. After the replacement is completed, the staff connects the hose 6 to the new filter element 5 and opens the corresponding valve 7. Then, the staff drives the installation shaft 9 to rotate through the motor 8 to make the first strong magnetic plate 10 away from the second strong magnetic plate 12, so that the tension spring 13 contracts to drive the limit plate 11 to extend and abut against the top of this filter element 5, thereby preventing the filter element 5 from falling off upward. Thus, the limitation is completed. Then, the staff installs the maintenance door 4 back and tightens it to prevent air leakage. Then, the staff can restart the cryogenic system to resume gas transmission for compressed air purification work.

[0044] Although embodiments of the present utility model have been shown and described, the specific embodiments are only interpretations of the present utility model and do not limit the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
