Description

Technical Field

[0001] This invention relates to the field of purging device technology, and more particularly to a liquid purging device for zeolite modules. Background Technology

[0002] Zeolite modules are a type of zeolite molecular sieve with a honeycomb structure. Impregnation with silica sol solution is a crucial step in the production of zeolite modules. After impregnation, excess silica sol solution needs to be blown away. Currently, the blowing air generated by the purging device cannot fully reach the zeolite modules to be purged; some air is wasted, resulting in low efficiency. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides an immersion purging device for zeolite modules, which enables the blowing air generated by the purging device to act completely on the zeolite module to be purged, thereby improving the utilization efficiency of the blowing air and reducing the time required for purging.

[0004] Technical Solution: To achieve the above objectives, the present invention provides an impregnation and purging device for zeolite modules, comprising an impregnation tank and a blower mechanism. The impregnation tank contains an impregnation solution for impregnating the zeolite modules, and a placement rack is provided on the impregnation tank for placing the zeolite modules to be purged. An air outlet hood is provided at the air outlet end of the blower mechanism, correspondingly covering the placement rack and abutting the zeolite modules on the placement rack, so that the air from the blower mechanism can completely penetrate the inner hole structure of the zeolite modules. Multiple impregnation tanks are arranged in a row, and the placement rack is mounted on a movable support, which can move the placement rack to each of the impregnation tanks. The air outlet hood is separately connected to the blower mechanism and is rotatably mounted on the movable support. When the air outlet hood is flipped up, it exposes the placement rack; when the air outlet hood is flipped down, it abuts the zeolite modules on the placement rack. All of the multiple impregnation tanks are provided with flat... The platform frame is equipped with guide rails that slide and engage with the movable support. The extension direction of the guide rails is consistent with the arrangement direction of the impregnation tanks. The platform frame is also equipped with a lifting mechanism for suspending the zeolite modules. The movable support includes a horizontal support and a vertical support. The bottom of the horizontal support is equipped with wheels that slide and engage with the guide rails, allowing the horizontal support to move along the guide rails. The vertical support is mounted on the horizontal support and has a longitudinal track that slides and engages with the longitudinal track. The placement rack is mounted on the vertical support. Both the placement rack and the vertical support are openwork supports to allow the impregnation liquid from the zeolite modules to drip back into the impregnation tanks. When the vertical support moves longitudinally, it can move into or out of the impregnation tanks. When the vertical support moves out of the impregnation tanks, it facilitates the use of a crane to lift the zeolite modules into or out of the impregnation tanks.

[0005] Furthermore, one end of the air outlet hood is provided with a downwardly extending extension rod, the lower end of which is hinged to a first hinge seat on the movable bracket; the movable bracket is also provided with a cylinder, the lower end of which is hinged to a second hinge seat on the movable bracket, and the upper end of which is hinged to the air outlet hood, and the extension and retraction of the cylinder causes the air outlet hood to rotate.

[0006] Furthermore, the placement rack has a limiting structure for limiting the position of the zeolite module; a height adjustment mechanism is provided between the placement rack and the movable support. When the height adjustment mechanism moves upward, it causes the zeolite module on the placement rack to be attached to the air outlet hood.

[0007] Furthermore, the blower mechanism includes a blower and an air supply pipeline. The air supply pipeline is provided with multiple branch pipes, which correspond to multiple impregnation tanks. An air valve is installed inside the branch pipe. An air inlet is provided on the air outlet cover. The air outlet end of the branch pipe is a flexible hose, and the air outlet end of the branch pipe is detachably connected to the air inlet.

[0008] Furthermore, the air inlet is located on one side of the air outlet hood, allowing air to enter laterally; the air outlet hood is equipped with a horizontal air guide plate, and there is an air passage gap between the air guide plate and the top of the air outlet hood; the air guide plate is obliquely arranged, and the lower oblique surface of the air guide plate is directly opposite the extension direction of the air inlet.

[0009] Furthermore, when the wind speed at the air inlet is between 3 m / s and 4 m / s, the angle between the air guide plate and the extension direction of the air inlet is between 30 degrees and 40 degrees.

[0010] Furthermore, the air guide plate is rotatably disposed inside the air outlet hood, and the air outlet hood is provided with a drive mechanism that drives the air guide plate to rotate; when the wind speed at the air inlet is between 3m / s and 4m / s, under the drive of the drive mechanism, the angle between the air guide plate and the extension direction of the air inlet is cyclically between 30 degrees and 40 degrees.

[0011] Beneficial effects: The immersion purging device for a zeolite module of the present invention has the following beneficial effects:

[0012] 1) The air outlet end of the blower mechanism has an air outlet cover, which is attached to the zeolite module so that the air outlet of the blower mechanism can be completely poured into the inner hole structure of the zeolite module, thereby improving the utilization rate of the air outlet, thus improving the purging efficiency and reducing the purging time.

[0013] 2) An inclined air guide plate is installed inside the air outlet hood. Under the action of the air guide plate, the air velocity entering the zeolite module from the air outlet hood is more uniform, which can further improve the purging efficiency. Attached Figure Description

[0025] The invention will now be further described with reference to the accompanying drawings.

[0026] As attached Figures 1 to 11 The aforementioned zeolite module immersion purging device includes an immersion tank 1 and a blower mechanism. The immersion tank 1 contains an immersion solution for immersing zeolite modules 2, which is a silica sol solution. A placement rack 3 is provided on the immersion tank 1 to hold the zeolite modules 2 to be purged. After the zeolite modules 2 have been immersed in the immersion tank 1, they are removed and placed on the placement rack 3, allowing any residual silica sol solution on the zeolite modules 2 to be purged and drip back into the immersion tank 1, thus recovering the silica sol solution.

[0027] The air outlet end of the blower mechanism is equipped with an air outlet cover 4, which is positioned above the placement rack 3 and spaced apart from it. When the zeolite module 2 is placed on the placement rack 3, the air outlet cover 4 can be attached to the zeolite module 2 on the placement rack 3, so that the air from the blower mechanism can be completely injected into the inner hole structure of the zeolite module 2, thereby improving the utilization efficiency of the air outlet, and making the blowing efficiency of residual impurities on the zeolite module 2 higher, while reducing the time required for blowing.

[0028] As attached Figure 1As shown, multiple impregnation tanks 1 are arranged in a row, and the placement rack 3 is mounted on a movable support 5. The movable support 5 can move the placement rack 3 to each of the impregnation tanks 1. Generally, the time required for the zeolite module 2 to be immersed in the impregnation tank 1 is greater than the time required to purge the residual impurity on the zeolite module 2. In addition, placing the placement rack 3 above the impregnation tank 1 will affect the placement and removal of the zeolite module 2. Therefore, one placement rack 3 corresponds to multiple impregnation tanks 1, and the multiple impregnation tanks 1 are purged alternately to save costs. The shorter the time required to purge the residual impurity on the zeolite module 2, the more impregnation tanks 1 one placement rack 3 can correspond to, and the lower the unit cost of the entire purging device. When the placement rack 3 is moved away from the impregnation tank 1, it also facilitates the placement and removal of the zeolite module 2 in the impregnation tank 1.

[0029] The air outlet cover 4 is separately connected to the blower mechanism, meaning it can be detached from the air outlet end of the blower mechanism. The air outlet cover 4 is rotatably mounted on the movable support 5 and can move with the movable support 5 above each impregnation tank 1, allowing a single air outlet cover 4 to correspond to multiple impregnation tanks 1, further reducing the unit cost of the purging device. (See attached image) Figure 4 As shown, when the air outlet hood 4 is flipped up, the placement rack 3 is exposed, making it convenient to place the zeolite module 2 on the placement rack 3 or remove the zeolite module 2 from the placement rack 3. (See attached diagram) Figure 5 As shown, when the air outlet cover 4 is flipped down, the air outlet cover 4 can be attached to the zeolite module 2 on the mounting bracket 3 so that the air outlet of the blower mechanism can be fully applied to the zeolite module 2.

[0030] One end of the air outlet hood 4 is provided with a downwardly extending extension rod 6, which separates the air outlet hood 4 from the placement rack 3. The upper end of the extension rod 6 is fixedly connected to the air outlet hood 4, and the lower end of the extension rod 6 is hinged to the first hinge seat on the movable support 5. The movable support 5 is also provided with a cylinder 8, the lower end of which is hinged to the second hinge seat on the movable support 5, and the upper end of which is hinged to the air outlet hood 4. The extension and retraction of the cylinder 8 causes the air outlet hood 4 to rotate. (See attached image) Figure 4 and 5 As shown, when cylinder 8 extends, it propels the air outlet shroud 4 to flip upwards; when cylinder 8 retracts, it drives the air outlet shroud 4 to flip downwards. There are two sets of cylinders 8, located on both sides of the air outlet shroud 4.

[0031] The shape of the air outlet hood 4 is adapted to the shape of the zeolite module 2. The edge of the lower opening of the air outlet hood 4 has a sealing strip, which improves the sealing effect of the edge of the air outlet hood 4 when it covers the zeolite module 2, preventing air leakage. A quick-release buckle is provided at the end of the air outlet hood 4 away from the extension rod 6. Figure 5When the hood is flipped over onto the zeolite module 2, the end of the hood 4 away from the extension rod 6 is connected to the movable bracket 5 via a quick-release buckle, thereby locking the hood 4 and further enhancing the seal between the hood 4 and the zeolite module 2.

[0032] The placement rack 3 has a limiting structure for limiting the position of the zeolite module 2, as shown in the attached diagram. Figure 4 and 5 A limiting strip 16 is set on the outer edge of the placement rack 3. The multiple limiting strips 16 cooperate to prevent the zeolite module 2 from wobbling in the horizontal direction when placed on the placement rack 3. A height adjustment mechanism is provided between the placement rack 3 and the movable support 5. When the height adjustment mechanism moves upward, it causes the zeolite module 2 on the placement rack 3 to press against the air outlet hood 4, as shown in the attached figure. Figure 7 As shown, the height adjustment mechanism is the adjustable support foot 17 at the bottom of the placement rack 3. By rotating the support foot 17, the height of the placement rack 3 can be changed, thereby adjusting the top height of the zeolite module 2 on the placement rack 3. When the air outlet hood 4 is flipped to the horizontal state, the lower opening of the air outlet hood 4 is sealed and fitted with the top of the zeolite module 2 to prevent air leakage and ensure that the air outlet of the blower mechanism is fully applied to the zeolite module 2.

[0033] Multiple impregnation tanks 1 are mounted on a platform frame 13 and are arranged linearly. The platform frame 13 is equipped with guide rails 14 that slide and engage with a movable support 5. The guide rails 14 extend vertically, and their extension direction is consistent with the arrangement direction of the impregnation tanks 1. The movable support 5 can move above each impregnation tank 1 via the guide rails 14. The platform frame 13 is also equipped with a lifting mechanism 15 for hoisting the zeolite modules 2. The lifting mechanism 15 is a gantry crane used to hoist the zeolite modules 2 into and out of the impregnation tanks 1.

[0034] As attached Figure 7 As shown, the movable support 5 includes a transverse support 18 and a longitudinal support 19. The bottom of the transverse support 18 is equipped with wheels that slide in conjunction with the guide rail 14. Driven by a motor, the transverse support 18 can move along the guide rail 14 via the wheels. The longitudinal support 19 is mounted on the transverse support 18 and has a longitudinal track. The longitudinal support 19 slides in conjunction with the longitudinal track. A longitudinal motor is also mounted on the transverse support 18, which drives a ball screw 25 to rotate. A nut on the ball screw 25 is mounted on the longitudinal support 19. When the ball screw 25 rotates, it pushes the longitudinal support 19 to move on the transverse support 18.

[0035] The placement rack 3 is mounted on the longitudinal moving support 19. Both the placement rack 3 and the longitudinal moving support 19 are openwork supports, allowing the impregnation liquid purged from the zeolite module 2 to drip back into the impregnation tank 1. When the longitudinal moving support 19 moves longitudinally, it can move into or out of the impregnation tank 1. When it moves out of the impregnation tank 1, it facilitates the use of a crane to lift the zeolite into or out of the impregnation tank 1. (See attached image) Figure 10 As shown, a support frame 20 is provided on the side of the impregnation tank 1, and a support roller 21 is provided on the longitudinal moving bracket 19. When the longitudinal moving bracket 19 moves above the impregnation tank 1, the support roller 21 contacts the support frame 20, so that part of the weight of the longitudinal moving bracket 19 is borne by the support frame 20.

[0036] As attached Figure 3 As shown, the blower mechanism includes a blower 9 and an air supply duct. The blower 9 is a centrifugal blower 9, and the air supply duct includes a main air duct 22. One end of the main air duct 22 is connected to the centrifugal blower 9, and the other end of the main air duct 22 is connected to multiple branch pipes 10. The multiple branch pipes 10 correspond to multiple impregnation tanks 1, and the air outlet end of the branch pipe 10 is located on the upper side of the impregnation tank 1. An air valve is installed inside each branch pipe 10, which can be used to open or close the corresponding branch pipe 10. The air outlet hood 4 is provided with an air inlet 11. The air outlet end of the branch pipe 10 is a flexible hose, and the air outlet end of the branch pipe 10 is detachably connected to the air inlet 11. When the air outlet hood 4 moves below the corresponding branch pipe 10, the air outlet hood 4 is connected to the air duct through the flexible hose and quick clamp.

[0037] The air outlet hood 4 is generally cubic in shape, and the air inlet 11 is located on one side of the air outlet hood 4. When the air outlet hood 4 is flipped down to cover the zeolite module 2 on the placement rack 3, the air outlet hood 4 is in a horizontal state, at which time the air inlet 11 allows air to enter laterally. To improve the purging effect, the airflow velocity provided by the blower mechanism is relatively fast, typically between 3 m / s and 4 m / s. (See attached...) Figure 6 As shown, the top of the air outlet hood 4 is closed, and the zeolite module 2 below the air outlet hood 4 has a vertical microporous structure. The horizontal airflow entering the air outlet hood 4 will impact the inner wall of the air outlet hood 4 and change direction downwards. According to the distance from the air inlet 11, the zeolite module 2 is divided into a near air outlet region 23 and a far air outlet region 24. After the horizontal airflow entering the air outlet hood 4 impacts the inner wall and moves downwards, most of it passes downwards through the far air outlet region 24 of the zeolite module 2. Therefore, the wind speed in the near air outlet region 23 and the far air outlet region 24 of the zeolite module 2 is different, and the purging speed of the residual impurity on the zeolite module 2 is also different. The near air outlet region 23 requires a longer purging time, thereby reducing the purging efficiency.

[0038] To address the issue of uneven airflow in the near-vent region 23 and the far-vent region 24 of zeolite module 2, as shown in the attached... Figure 7 and 8As shown, an air guide plate 12 is transversely spaced inside the air outlet hood 4, and there is an air passage gap between the air guide plate 12 and the top of the air outlet hood 4. The air guide plate 12 is obliquely arranged, and the lower oblique surface of the air guide plate 12 is directly opposite to the extension direction of the air inlet 11. The air guide plate 12 is used to make the air outlet hood 4 emit air evenly.

[0039] As attached Figure 7 As shown, if the air guide plate 12 is a horizontal plate, then the air guide plate 12 has little effect on the lateral airflow entering the air outlet hood 4, and the wind speed in the far air outlet area 24 will still be greater than the wind speed in the near air outlet area 23; however, if the air guide plate 12 is a vertical plate, then the lateral airflow entering the air outlet hood 4 is almost entirely blocked by the air guide plate 12, and at this time the wind speed in the near air outlet area 23 is greater than the wind speed in the far air outlet area 24; therefore, during the process of the air guide plate 12 rotating from a horizontal state to a vertical state, the wind speed in the near air outlet area 23 will gradually increase, while the wind speed in the far air outlet area 24 will gradually decrease. By setting a wind speed sensor to detect the wind speed in the near air outlet area 23 and the far air outlet area 24, and by continuously adjusting the tilt angle of the air guide plate 12, an angle can be found that makes the wind speeds in the near air outlet area and the far air outlet area 24 equal.

[0040] In the actual experiment, the length, width, and height of the inner wall of the air outlet hood 4 are 1525mm, 1096mm, and 600mm, respectively; the air inlet 11 is circular with a diameter of 500mm, and the distance between the center of the air inlet 11 and the bottom of the air outlet hood 4 is 300mm; the length of the air guide plate 12 is the same as the width of the air outlet hood 4, which is 1096mm; the width of the air guide plate 12 is the same as the diameter of the air inlet 11, which is 500mm; the thickness of the air guide plate 12 is... A 30mm diameter air guide plate 12 has a rotating shaft 7 located in its center. The rotating shaft 7 is positioned along the length of the air guide plate 12, allowing the air guide plate 12 to rotate within the air outlet hood 4, making its angle adjustable. The rotating shaft 7 is at the same horizontal height as the circular air inlet 11. When the air guide plate 12 is rotated to a vertical position, its upper and lower ends are flush with the upper and lower edges of the air inlet 11, respectively. Furthermore, the rotating shaft 7 is located at the center of the length of the air outlet hood 4. Wind speed sensors are installed at the air inlet 11, the near-air outlet area 23, and the far-air outlet area 24 to detect wind speed.

[0041] In the following experiment, the air guide plate 12 rotates clockwise from a horizontal position.

[0042] In the first set of control experiments, the wind speed measured at the air inlet 11 was 3.73 m / s, the angle between the air guide plate 12 and the extension direction of the air inlet 11 was 10 degrees, the wind speed measured in the near air outlet area 23 was 2.54 m / s, and the wind speed measured in the far air outlet area 24 was 3.29 m / s.

[0043] In the second set of control tests, the wind speed measured at air inlet 11 was 3.59 m / s, the angle between the air guide plate 12 and the extension direction of air inlet 11 was 20 degrees, the wind speed measured in near air outlet area 23 was 2.72 m / s, and the wind speed measured in far air outlet area 24 was 3.11 m / s.

[0044] In the third set of control tests, the wind speed measured at air inlet 11 was 3.69 m / s, the angle between the air guide plate 12 and the extension direction of air inlet 11 was 30 degrees, the wind speed measured in near air outlet area 23 was 2.86 m / s, and the wind speed measured in far air outlet area 24 was 3.02 m / s.

[0045] In the fourth group of control tests, the wind speed measured at air inlet 11 was 3.72 m / s, the angle between the air guide plate 12 and the extension direction of air inlet 11 was 40 degrees, the wind speed measured in near air outlet area 23 was 2.99 m / s, and the wind speed measured in far air outlet area 24 was 2.88 m / s.

[0046] In the fifth group of control tests, the wind speed measured at air inlet 11 was 3.63 m / s, the angle between the air guide plate 12 and the extension direction of air inlet 11 was 50 degrees, the wind speed measured in near air outlet area 23 was 3.14 m / s, and the wind speed measured in far air outlet area 24 was 2.67 m / s.

[0047] The above experimental data shows that as the angle between the air guide plate 12 and the air inlet 11 changes from 30 degrees to 40 degrees, the wind speed in the near-air inlet region 23 gradually increases and exceeds the wind speed in the far-air inlet region 24. Therefore, when the wind speed at the air inlet 11 is between 3 m / s and 4 m / s, the angle between the air guide plate 12 and the air inlet 11 should be set between 30 degrees and 40 degrees, and then the air guide plate 12 should be fixed so that the wind speed in the near-air inlet region 23 and the wind speed in the far-air inlet region 24 tend to be equal, thereby reducing the time required to purge the residual impurity on the zeolite module 2 and improving the purging efficiency.

[0048] In another embodiment, the air guide plate 12 is rotatably mounted inside the air outlet shroud 4 via a rotating shaft 7. The air outlet shroud 4 is equipped with a drive mechanism that rotates the air guide plate 12; that is, a motor is installed outside the air outlet shroud 4, and the motor drives the rotating shaft 7 to reciprocate. When the wind speed at the air inlet 11 is between 3 m / s and 4 m / s, under the drive of the motor, the angle between the air guide plate 12 and the extending direction of the air inlet 11 cycles between 30 degrees and 40 degrees, making it easier for the wind speed in the near-air outlet region 23 and the far-air outlet region 24 to approach equality during dynamic changes.

[0049] The working method of this invention is as follows: The overhead crane lifts the zeolite module 2 into the corresponding impregnation tank 1 to impregnate it with silica sol solution. After the impregnation of the zeolite module 2 is completed in a certain impregnation tank 1, the corresponding overhead crane lifts the zeolite module 2, and then the moving support 5 moves to the location of the corresponding impregnation tank 1, and pushes the placement rack 3 and the air outlet hood 4 directly above the impregnation tank 1. Then the air outlet hood 4 is flipped up, the overhead crane places the zeolite module 2 on the placement rack 3, and the air outlet hood 4 is flipped down to cover the zeolite module 2. The air inlet 11 of the air outlet hood 4 and the corresponding air flow pipe are connected through a hose and a quick clamp. The air valve on the corresponding air flow pipe is opened, the fan 9 is started, and the air outlet hood 4 blows out air to blow away the silica sol solution remaining in the zeolite module 2.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
