A zeolite rotating drum which is easy to maintain

Abstract

This invention belongs to the field of zeolite rotary drum technology, specifically relating to a zeolite rotary drum that is easy to maintain. It includes a shell and a base fixedly mounted on the shell. A rotating frame is rotatably mounted on the base, and the rotating frame includes hollow columns. Multiple clamping plate assemblies are arrayed and fixedly mounted on the rotating frame, with the hollow columns positioned between adjacent clamping plate assemblies. This easy-to-maintain zeolite rotary drum uses a lifting mechanism to drive the fan-shaped plate up and down, which in turn links the elastic rod, rotating sleeve, pull rod, and limiting plate to achieve rapid unlocking or locking of a single-station molecular sieve module. Simultaneously, a retractable bearing slide is provided on the clamping plate assembly. After the limiting is released, the slide carrying the molecular sieve module can be pulled outward along the guide rail. Automatic limiting triggering is achieved through a spring-driven stop bar and a pressing block within the bearing plate: when the slide is pulled out, the pressing block disengages from the clamping plate assembly, and the stop bar automatically retracts and unlocks; when the slide is reset, the pressing block abuts against the clamping plate assembly, pushing the stop bar to automatically extend and lock.

Description

Technical Field

[0001] This invention belongs to the field of zeolite rotary drum technology, specifically relating to a zeolite rotary drum that is easy to maintain. Background Technology

[0002] Zeolite rotary drums are a new generation of core adsorption and concentration equipment in the field of industrial volatile organic compound (VOC) waste gas treatment. As an optimized and upgraded form of traditional disc-type zeolite rotors, they adopt a vertical cylindrical modular structure with built-in high-silicon-alumina ratio hydrophobic zeolite molecular sieve adsorption modules. Individual modules can be independently disassembled and replaced, and the equipment has outstanding advantages such as compact structure, small footprint, and convenient transportation, installation, and maintenance. Relying on the selective adsorption and thermal desorption characteristics of zeolite molecular sieves, the equipment completes the cycle operation in the separated adsorption and desorption functional zones through the low-speed continuous operation of the drum. It can continuously and efficiently adsorb and purify large-volume, low-concentration VOCs waste gas. The purified gas can be directly discharged in compliance with standards. At the same time, the adsorption material is regenerated by reverse blowing with 180-220℃ high-temperature hot air.

[0003] In conventional zeolite rotary drum structures, the molecular sieve adsorption modules are mostly fixed to the rotating frame of the drum using bolts and integral embedding. When the molecular sieve modules fail due to adsorption saturation, damage, or blockage and need to be replaced or maintained, the fasteners of the corresponding modules must be removed one by one using tools, and sometimes the entire frame of the drum needs to be disassembled to complete the module replacement. In addition, the module limiting structure of existing zeolite rotary drums cannot achieve independent and rapid unlocking of individual workstation modules. This not only makes the operation process cumbersome and the maintenance work time-consuming, but also significantly increases the downtime cost of the equipment. At the same time, the narrow operating space inside the equipment poses a high safety risk to the operators. Summary of the Invention

[0004] The purpose of this invention is to provide a zeolite rotary drum that is easy to maintain in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A zeolite rotating drum that is easy to maintain includes a shell and a base fixedly mounted on the shell. A rotating frame is rotatably mounted on the base. The rotating frame includes a hollow column. Multiple clamping plate groups are fixedly arranged in an array on the rotating frame. The hollow column is arranged between adjacent clamping plate groups. An elastic rod is slidably mounted inside the hollow column. The elastic rod includes multiple crossbars that slide through the hollow column. A sector-shaped plate is raised and lowered on the base and movably abuts against the elastic rod. It also includes: A bearing slide is arranged on a clamping plate assembly from top to bottom. A molecular sieve module is movably arranged on the bearing slide. A limiting plate is slidably arranged through the clamping plate assembly and is movably connected to the bearing slide. A rotating sleeve is symmetrically mounted on a hollow column. The rotating sleeve is connected to a limiting plate. An arc groove is provided on the rotating sleeve and is fitted onto a crossbar. The rotating sleeve is driven to rotate by the movement of an elastic rod. A baffle bar is slidably mounted on a bearing slide block and abuts against the molecular sieve module.

[0006] As a further optimization of the present invention, an extension seat is fixedly provided on the rotating sleeve, and adjacent extension seats are aligned. Pull rods are slidably provided on both sides of the clamping plate assembly. A connecting rod is hinged between the pull rod and the extension seat. An inclined groove is provided on the limiting plate, and the end of the pull rod is slidably provided in the inclined groove.

[0007] As a further optimization of the present invention, the bearing slide includes a fixing plate, the fixing plate is fixedly mounted on the clamping plate assembly, a guide rail is fixedly mounted on the fixing plate, a sliding plate is slidably mounted on the fixing plate via the guide rail, and a bearing plate is fixedly mounted on the sliding plate.

[0008] As a further optimization of the present invention, the bearing plate includes a plate body, the plate body is fixedly mounted on the slide plate, the plate body has limiting grooves on both sides, the limiting plate is embedded in the limiting grooves, and the plate body has a receiving groove.

[0009] As a further optimization of the present invention, the baffle is slidably disposed in the receiving groove, a spring is connected between the baffle and the receiving groove, the baffle is angled on both sides, and a squeezing block is slidably disposed through both sides of the receiving groove.

[0010] As a further optimization of the present invention, one end of the extrusion block abuts against the beveled edge of the baffle, and the other end of the extrusion block is rounded and movably abuts against the clamping plate assembly.

[0011] As a further optimization of the present invention, the rotating frame includes a mounting frame fixedly mounted on the base, a base plate rotatably mounted on the mounting frame, an array of hollow columns fixedly mounted on the base plate, a top plate fixedly connected to the base plate through the hollow columns, a clearance groove provided on the hollow columns, a crossbar passing through the clearance groove through the hollow columns, a pulley array rotatably mounted on the mounting frame that abuts against the base plate, and an elastic rod passing through the base plate.

[0012] As a further optimization of the present invention, the elastic rod includes a rod body, the crossbar is fixedly mounted on the rod body, an elastic element is provided between the rod body and the hollow column, and a universal ball is provided at the lower end of the elastic rod, the universal ball being in movable contact with the sector plate.

[0013] As a further optimization of the present invention, downward-facing wing plates are provided on both sides of the fan-shaped plate, and a lifting mechanism is fixedly provided on the base, with the output end of the lifting mechanism fixed to the fan-shaped plate.

[0014] The beneficial effects of this invention are as follows: 1. Unlike existing technologies, in actual use, the lifting mechanism drives the sector plate to rise and fall, which in turn links the elastic rod, rotating sleeve, pull rod and limit plate to achieve quick unlocking or locking of the single-station molecular sieve module. At the same time, the clamping plate assembly is equipped with a pull-out bearing slide. After the limit is released, the slide plate carrying the molecular sieve module can be pulled out along the guide rail without the need for special tools, which greatly simplifies the module replacement process and shortens the equipment downtime.

[0015] 2. Unlike existing technologies, in actual use, automatic limit triggering is achieved through the spring-linked stop bar and the squeezing block inside the bearing plate: when the slide is pulled out, the squeezing block disengages from the clamping plate assembly, and the stop bar automatically retracts and unlocks; when the slide is reset, the squeezing block abuts against the clamping plate assembly and pushes the stop bar to automatically extend and lock, without the need for additional manual operation.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1, such as Figure 1 - Figure 3 As shown, a zeolite rotary drum that is easy to maintain includes a shell 1 and a base 14 fixedly installed at the bottom of the shell 1. The shell 1 is a sealed rectangular cavity structure, providing a closed working space for waste gas purification operations. The base 14 provides a stable support foundation for the overall rotating and driving structure of the equipment. A rotating frame 2 is rotatably mounted on the base 14. An air inlet 12 is opened on one side wall of the shell 1 for receiving the organic waste gas to be purified. An exhaust port 11 is opened at the center of the upper end of the shell 1, located above the rotating frame 2, for... The purified gas is discharged; a hot air pipe 13 connected to a heat source is provided on the shell 1, and a regeneration tank 131 connected to a collection device is fixedly provided on the opposite side of the air inlet 12. Multiple sets of clamping plate groups 3 are fixedly arranged in a ring array on the rotating frame 2. The regeneration tank 131 is located on the radial outer side of the clamping plate group 3, and the air outlet of the hot air pipe 13 is located on the radial inner side of the clamping plate group 3. The air outlet of the hot air pipe 13 and the slot of the regeneration tank 131 are arranged radially opposite to each other. The hot air pipe 13 is used to connect high-temperature regeneration hot air to desorb and regenerate the molecular sieve module 4 that is saturated with adsorption.

[0020] like Figures 2-4 , Figure 8 and Figure 12As shown, the rotating frame 2 includes a mounting frame 24 fixedly installed at the center of the base 14. A circular base plate 21 is rotatably mounted on the upper end of the mounting frame 24 via a rotating shaft. The base plate 21 is connected to a drive mechanism (existing technology, not shown in the figure) via a chain. Multiple pulleys 241 are rotatably arranged in a ring array on the upper end face of the mounting frame 24. The wheel surfaces of the pulleys 241 are in movable contact with the lower surface of the base plate 21 to provide rolling support for the rotation of the base plate 21, reduce rotational friction, and ensure rotational stability. Multiple hollow columns 23 are fixedly arranged in a ring array on the upper end face of the base plate 21. A circular top plate 22 is fixedly connected to the upper end of the multiple hollow columns 23. The base plate 21, hollow columns 23, and top plate 22 together form a cage-like rotating frame body. Multiple sets of clearance grooves 231 are opened along the axial direction on the side wall of the hollow columns 23. The clearance grooves 231 are radially penetrating through groove structures.

[0021] like Figure 4 - Figure 5 As shown, each clamping plate group 3 includes two parallel vertical clamping plates. The inner sides of the vertical clamping plates are connected to each other by a hollow connecting frame 31. An installation gap is reserved between two adjacent clamping plate groups 3. The hollow column 23 is correspondingly set in the gap between adjacent clamping plate groups 3. Each clamping plate group 3 is fixedly provided with multiple bearing slides 8 from top to bottom. Molecular sieve modules 4 (made of recycled material, which is existing technology and will not be described in detail) are movably arranged on the bearing slides 8 to adsorb and intercept organic pollutants in the waste gas.

[0022] like Figure 10 As shown, the supporting slide 8 includes a fixing plate 81, which is fixedly installed between two vertical clamping plates of the clamping plate assembly 3 by fasteners. Two parallel guide rails 811 are fixedly provided on the upper end surface of the fixing plate 81. A sliding plate 82 is slidably installed on the fixing plate 81 via the guide rails 811. The sliding plate 82 can be slid out radially outward along the guide rails 811. A supporting plate 83 is fixedly provided on the upper end surface of the sliding plate 82. The supporting plate 83 is used to support the molecular sieve module 4. The supporting plate 83 includes a plate body 831, which is fixed to the upper end surface of the sliding plate 82. The left and right side walls of the plate body 831 are provided with inwardly recessed limiting grooves 832. The upper end surface of the plate body 831 near the outer position is provided with a receiving groove 833, which extends along the length direction of the plate body 831.

[0023] like Figure 11As shown, a baffle 9 is slidably arranged in the receiving groove 833. When the upper end of the baffle 9 is higher than the upper end of the plate 831, it can abut against the side wall of the molecular sieve module 4 placed on the plate 831, and cooperate with the hollow connecting frame 31 to realize the front and rear limit of the molecular sieve module 4. A spring 91 is fixedly connected between the end of the baffle 9 and the groove wall of the receiving groove 833, which provides the baffle 9 with a pulling force to retract into the receiving groove 833 under normal conditions. Both sides of the baffle 9 are beveled to form a wedge-shaped guide surface. Both sides of the receiving groove 833 are slidably arranged with extrusion blocks 92. The inner end of the extrusion block 92 is movably abutted against the beveled edge of the baffle 9. The outer end of the extrusion block 92 is rounded and can extend out of the side of the plate 831 to movably abut against the inner side of the vertical clamping plate of the clamping plate assembly 3.

[0024] like Figure 8 - Figure 9 As shown, an elastic rod 5 is slidably disposed in the inner cavity of the hollow column 23. The elastic rod 5 includes a rod body 51 disposed along the axial direction of the hollow column 23. Multiple crossbars 52 are fixedly disposed along the axial direction on the side wall of the rod body 51. The number of crossbars 52 corresponds one-to-one with the number of bearing slides 8 in the same row. The crossbars 52 slide through the side wall of the hollow column 23 through the clearance groove 231 on the hollow column 23. The lower end of the rod body 51 slides through the bottom plate 21 and extends below the bottom plate 21. A universal ball 511 is installed at the lower end of the rod body 51. An elastic element 53 is disposed between the upper end of the rod body 51 and the top of the inner cavity of the hollow column 23. In this embodiment, the elastic element 53 is a compression spring, which provides a downward elastic thrust to the rod body 51 under normal conditions, so that the rod body 51 is kept in a low locked position.

[0025] like Figure 5 - Figure 7As shown, two rotating sleeves 7 are symmetrically rotatably mounted on the outer wall of the hollow column 23. An arc groove 71 is formed on the side wall of each rotating sleeve 7. The arc groove 71 is an inclined arc-shaped through groove. The arc groove 71 is movably mounted on the corresponding horizontal bar 52. When the horizontal bar 52 moves up and down with the bar 51, the rotating sleeve 7 is driven to reciprocate around the hollow column 23 through the guiding action of the arc groove 71. An extension seat 72 is fixedly mounted on the outer wall of the rotating sleeve 7. The extension seats 72 of two adjacent rotating sleeves 7 on the same hollow column 23 are aligned vertically. Pull rods 73 are slidably mounted on the outer sides of the two vertical clamping plates of the clamping plate assembly 3. The pull rods 73 move along the rotating frame 2... The pull rod 73 is radially arranged, and the rod body is hinged to the two adjacent extension seats 72. When the rotating sleeve 7 rotates, the extension seats 72 can drive the connecting rod 731 to swing, thereby pulling the pull rod 73 to slide back and forth radially. A limit plate 6 is slidably arranged through the clamping plate group 3. The limit plate 6 has an inclined groove 61. The outer end of the pull rod 73 is slidably arranged in the inclined groove 61. When the pull rod 73 slides radially, the limit plate 6 can be guided by the inclined groove 61 to extend and retract horizontally. One end of the limit plate 6 can be embedded in the limiting grooves 832 arranged on both sides of the plate body 831 to achieve radial limit locking of the bearing slide 8.

[0026] like Figure 12 As shown, a sector plate 10 is raised and lowered on the base 14. The center of the sector plate 10 coincides with the rotation center of the rotating frame 2. The arc length of the sector plate 10 corresponds to the size of the single set of clamping plates 3. The upper end face of the sector plate 10 can move and abut against the universal ball 511 at the lower end of the elastic rod 5. The left and right sides of the sector plate 10 are provided with downwardly extending wing plates. A lifting mechanism 101 is fixedly installed on the base 14. In this embodiment, the lifting mechanism 101 adopts an electric push rod. It can also adopt a linear drive mechanism such as a cylinder or hydraulic cylinder according to the on-site working conditions. The output end of the lifting mechanism 101 is fixedly connected to the middle of the sector plate 10 and is used to drive the sector plate 10 to rise and fall vertically to realize the switching between the maintenance gear and the normal operation gear.

[0027] It should be noted that during normal operation, the organic waste gas to be purified enters the inner cavity of the shell 1 through the air inlet 12. The waste gas passes radially through the molecular sieve module 4 carried by the clamping plate group 3 on the rotating frame 2. The organic pollutants in the waste gas are adsorbed and trapped by the molecular sieve module 4. The purified clean gas gathers in the central inner cavity of the rotating frame 2 and is finally discharged from the exhaust port 11 at the top of the shell 1. During this process, the rotating frame 2 is driven to rotate continuously by an external drive mechanism. When the molecular sieve module 4 rotates between the hot air pipe 13 and the regeneration tank 131, the high-temperature hot air output from the hot air pipe 13 passes radially in the opposite direction through the molecular sieve module 4, desorbing the organic pollutants adsorbed by the molecular sieve. The desorbed waste gas is discharged outside the shell 1 through the regeneration tank 131, completing the regeneration of the molecular sieve module 4 and realizing continuous and uninterrupted waste gas purification operation of the equipment.

[0028] When it is necessary to replace or maintain a molecular sieve module 4 that has failed to adsorb or is damaged, first stop the air intake of the equipment, then start the lifting mechanism 101. The lifting mechanism 101 drives the sector plate 10 to rise to the maintenance position. By rotating the rotating frame 2, the clamping plate group 3 corresponding to the molecular sieve module 4 to be replaced is rotated to be directly above the sector plate 10. The upper end face of the sector plate 10 abuts against the universal ball 511 at the lower end of the corresponding elastic rod 5 on both sides of the work position, and presses the rod body 51 upward, so that the rod body 51 overcomes the elastic force of the elastic element 53 and slides upward along the hollow column 23. The crossbar 52 on the body 51 rises synchronously with the body 51. The crossbar 52 slides along the arc groove 71 on the rotating sleeve 7, thereby driving the rotating sleeve 7 to rotate around the hollow column 23. While the rotating sleeve 7 is rotating, it drives the connecting rod 731 to swing through the extension seat 72 on it. The connecting rod 731 pulls the pull rod 73 to slide outward along the radial direction of the rotating frame 2. The outer end of the pull rod 73 slides along the inclined groove 61 on the limiting plate 6, driving the limiting plate 6 to slide outward horizontally, so that the limiting plate 6 exits from the limiting grooves 832 on both sides of the plate body 831, releasing the radial limitation on the bearing slide 8.

[0029] At this time, the operator can slide the slide plate 82 carrying the molecular sieve module 4 along the guide rail 811 on the fixed plate 81 towards the radially outward side of the rotating frame 2. As the slide plate 82 moves outward, the pressing blocks 92 on both sides of the bearing plate 83 disengage from the vertical clamping plates of the clamping plate group 3. Under the tension of the spring 91, the baffle 9 slides and retracts into the receiving groove 833. The pressing blocks 92 are pushed into the receiving groove 833 by the oblique edge of the baffle 9. The baffle 9 is completely stored in the receiving groove 833, releasing the abutment limit on the molecular sieve module 4. At this time, the molecular sieve module 4 corresponding to the workstation can be directly removed from the bearing plate 83 to complete the disassembly operation.

[0030] When installing the new molecular sieve module 4, place it stably on the plate 831 of the support plate 83. Then, push the slide plate 82 inward along the guide rail 811 to reset it. As the slide plate 82 moves inward, the outer end of the extrusion block 92 abuts against the vertical clamping plate of the clamping plate assembly 3. The clamping plate assembly 3 pushes the extrusion block 92 to slide into the receiving groove 833. The inner end of the extrusion block 92 pushes the baffle 9 upward against the tension of the spring 91 through the beveled edge of the baffle 9. The upper end surface of the baffle 9 is higher than the upper end surface of the plate 831 and abuts against the side wall of the molecular sieve module 4. The molecular sieve module 4 is positioned at the front and rear. Then, the rotating frame 2 is rotated to separate the elastic rod 5 from the sector plate 10. The elastic rod 5 slides down and resets under the elastic force of the elastic element 53. The crossbar 52 drives the rotating sleeve 7 to rotate in the opposite direction, and then the connecting rod 731 pushes the pull rod 73 to slide outward. The pull rod 73 drives the limiting plate 6 to slide inward through the inclined groove 61, so that the limiting plate 6 is re-embedded in the limiting groove 832 of the bearing plate 83, thus locking the bearing slide 8. This completes the replacement and installation of the specified molecular sieve module 4 at this station.

[0031] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
