Description

Technical Field

[0001] This invention relates to the field of desorption device technology, and in particular to a desorption device housing and its assembly method. Background Technology

[0002] In fields such as industrial organic waste gas treatment and solvent recovery, desorption devices are used to achieve pollutant separation and resource recovery. Specifically, nitrogen gas that has adsorbed organic matter is cooled to saturate the organic matter carried in the nitrogen gas and release it, thereby achieving nitrogen purification and regeneration and organic matter recycling. In existing technologies, the plates (including side plates, top plates, and bottom plates) of the desorption device shell are mostly made of stainless steel. During the assembly of the shell, welding is commonly used to fix and connect the plates to the frame and to each other, forming a unified structure through welds to ensure the shell's airtightness and structural integrity. However, the recovered materials processed by desorption devices are highly complex, typically containing organic compounds such as ketones, esters, and halogenated hydrocarbons, as well as acidic substances such as hydrochloric acid, sulfuric acid, and acetic acid, which are highly corrosive to conventional materials. Furthermore, the desorption devices operate under harsh conditions, including large temperature and pressure fluctuations, high-frequency vibrations, and long-term high-speed fluid scouring. Desorption devices made of conventional materials cannot withstand the corrosion of recovered materials for long periods, exhibiting problems such as deformation, cracking, and perforation, resulting in a very short lifespan. While using high-strength, corrosion-resistant metals (C276, slag, etc.) can solve the corrosion problem, their cost is extremely high, making them unaffordable for most users.

Detailed Implementation

[0017] This invention provides a desorption device housing and its assembly method. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0018] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0019] In this invention, "front" indicates the beginning of the gas flow direction inside the desorption device, "rear" is the opposite of "front"; and left and right are perpendicular to the front and back directions.

[0020] Please see Figures 1 to 7As shown, the present invention provides a shell for a desorption device, comprising: a frame 1, two first side plates 2, a top plate assembly 4, a second side plate 5, a third side plate 6, and a bottom plate assembly 7; the frame 1 is constructed by welding square tubes 11, possessing high structural strength and good resistance to deformation, effectively supporting the entire shell structure; at least one side of the square tubes 11 is provided with a T-shaped hole 111; the first side plates 2, second side plates 5, third side plates 6, top plate assembly 4, and bottom plate assembly 7 are all made of phenolic epoxy vinyl resin composite fiberboard, possessing excellent corrosion resistance and lightweight high strength characteristics, effectively resisting chemical corrosion under complex working conditions; the two first side plates 2 are respectively mounted on the frame 1 via connecting assemblies 3. The top plate assembly 4 is installed on the top of the frame 1 via the connecting assembly 3; the second side plate 5 is installed on the front side of the frame 1 via the connecting assembly 3; the third side plate 6 is installed on the rear side of the frame 1 via the connecting assembly 3; the bottom plate assembly 7 is installed on the inner bottom of the frame 1; several first connecting pieces 71 in the shape of "7" are fixed on the side of the bottom plate assembly 7 near the two first side plates 2; the first connecting pieces 71 are installed on the bottom of the frame 1 via the connecting assembly 3; through the coordinated cooperation of the first side plate 2, the second side plate 5, the third side plate 6, the top plate assembly 4 and the bottom plate assembly 7, the fully enclosed structure design of the shell is realized, effectively isolating the internal gas from the external environment, and ensuring the safety and stability of the desorption process.

[0021] The connecting assembly 3 includes a limiting plate 31, a connecting post 32, a spring piece 33, and a fastener 34; the limiting plate 31 is embedded inside the square tube 11; one end of the connecting post 32 is fixed to the limiting plate 31, and the other end extends to the outside of the T-shaped hole 111; one end of the spring piece 33 is fixed to one end of the limiting plate 31, and the other end is a free end; there is a gap between the limiting plate 31 and the spring piece 33, which is used to engage the side wall of the square tube 11; the spring piece 33 is provided with a through hole 331 for the connecting post 32 to pass through; the fastener 34 is screwed to the connecting post 32; and is used to fix the first side plate 2, the second side plate 5, the third side plate 6, the top plate assembly 4, or the first connecting piece 71 to the square tube 11.

[0022] During installation, the connecting post 32 is held to push the limiting plate 31 into the square tube 11 through the horizontal section of the T-shaped hole 111. Then, the connecting post 32 is rotated so that the limiting plate 31 is perpendicular to the horizontal section of the T-shaped hole 111. At this time, the free end of the spring piece 33 is located outside the square tube 11 and is tightly attached to the side wall of the square tube 11 due to its own elasticity, so as to position the limiting plate 31 inside the square tube 11. At the same time, the bottom of the limiting plate 31 abuts against the adjacent inner wall of the square tube 11. The connecting post 32 slides into the vertical section of the T-shaped hole 111, further limiting the movement of the limiting plate 31 along the length direction of the square tube 11, ensuring that the connecting assembly 3 is stable and does not loosen. At this time, the preset mounting holes on the first side plate 2, the second side plate 5, the third side plate 6, the top plate assembly 4, or the first connecting piece 71 are fitted into the exposed end of the connecting post 32, and then the fastener 34 is tightened to press it onto the surface of the plate, so as to achieve quick assembly. With the above configuration, each panel is detachably connected to the frame 1 without welding, thus avoiding the risk of weld corrosion. At the same time, the panels made of phenolic epoxy vinyl resin composite fiber can resist the continuous erosion of corrosive recycled materials, effectively improving the corrosion resistance and sealing reliability of the shell.

[0023] It should be noted that T-shaped holes 111 are provided on the two adjacent side walls of the square tube 11 located at the corner of the frame 1 to accommodate the connection requirements between the same square tube 11 and the plates located on different sides of the frame 1.

[0024] In practical applications, a sealant layer can be pre-applied to the edges of the phenolic epoxy vinyl ester composite fiber panels. This sealant layer has elastic deformation capability and adhesion. During installation, the sealant layer is pressed and squeezed between the panels and the square tube 11, and between the panels themselves, causing it to flow elastically and fully fill the tiny gaps between the panels and the square tube 11, forming a reliable sealing interface. Alternatively, after assembly, sealant can be applied to the joints of the edges of each panel. Through the filling effect of the sealant, gaps that may occur between adjacent panels can be filled, preventing the leakage of corrosive gases or liquids.

[0025] In a preferred embodiment, see [reference] Figure 3 , 5 The spring piece 33 is provided with a curved part 332 protruding away from the limiting plate 31, so that the spring piece 33 forms a natural elastic arch structure. When the plate is installed on the connecting assembly 3, the spring piece 33 is compressed and undergoes elastic deformation, so that the side wall of the square tube 11 is more tightly clamped between the limiting plate 31 and the spring piece 33, effectively improving the connection stability of the connecting assembly 3 on the square tube 11, thereby improving the connection stability of the first side plate 2, the second side plate 5, the third side plate 6, the top plate assembly 4 and the bottom plate assembly 7 with the frame 1 respectively.

[0026] Preferably, the fixed end of the spring piece 33 has an n-shaped structure, and the limiting plate 31 is fixed on the inner side of the fixed end of the spring piece 33 so that an elastic clamping structure is formed between the limiting plate 31 and the spring piece 33; in addition, a through hole 331 is provided to avoid positional interference between the spring piece 33 and the connecting post 32, thereby ensuring that the spring piece 33 and the limiting plate 31 cooperate to clamp the side wall of the square tube 11.

[0027] In this embodiment, the connection between the connecting post 32 and the plate has the following two implementation methods: First implementation method: as follows Figure 5 As shown, the connecting column 32 is provided with a threaded section 321, and the fastener 34 is a nut. The nut is screwed into the threaded section 321. The tightening force of the nut presses and fixes the first side plate 2, the second side plate 5, the third side plate 6, the top plate assembly 4 or the first connecting piece 71 onto the outer wall of the square tube 11. This is suitable for scenarios where the plate thickness is relatively thin and there is no need to hide the fastener 34.

[0028] The second implementation method: as follows Figure 6 As shown, the connecting column 32 has a threaded hole 322, and the fastener 34 is a screw. The screw is screwed into the threaded hole 322, and the plate and square tube 11 are fixed by the pressing action of the screw head. It is suitable for scenarios where the plate is thick, two or more plates are connected, or the appearance flatness requirement is high.

[0029] In a preferred embodiment, see [reference] Figure 3 The first side plate 2, the second side plate 5, or the third side plate 6 facing the frame 1 are provided with a limiting strip 61. The limiting strip 61 extends horizontally, and the upper surface of the limiting strip 61 abuts against the bottom of the corresponding square tube 11. For the square tube 11 extending in the left and right direction, the vertical section of the T-shaped hole 111 on its side wall extends downward, that is, the lower end of the limiting plate 31 of the connecting component 3 abuts against the inner bottom of the square tube 11. Combined with the limiting effect of the limiting strip 61 and the square tube 11, the vertical movement of the connecting component 3 and the side plate as a whole and the displacement in the left and right directions are effectively prevented.

[0030] For the square tube 11 extending in the front-back direction, the vertical section of the T-shaped hole 111 on its side wall extends toward the inside of the frame 1. That is, the ends of the limiting plates 31 of the two symmetrically arranged connecting components 3 abut against the side wall of the square tube 11 toward the inside of the frame 1. Through the cooperation of the two corresponding connecting components 3, the top plate assembly 4 is stably connected in the front-back direction.

[0031] In a preferred embodiment, see [reference] Figure 3The first side plate 2, the second side plate 5, the third side plate 6, or the top plate assembly 4 have countersunk holes 62 on their surfaces facing the frame 1. The countersunk holes 62 correspond to the T-shaped holes 111 of the square tube 11, and the projection area of ​​the T-shaped holes 111 is located within the projection area of ​​the countersunk holes 62. A sealing gasket 63 is embedded at the edge of the countersunk holes 62. The countersunk holes 62 are used to avoid the spring sheet 33, preventing interference between the spring sheet 33 and the surface of the plate, and ensuring a tight fit between the plate and the side wall of the square tube 11. At the same time, a sealing gasket 63 is provided at the edge of the countersunk holes 62. The sealing gasket 63 is made of a corrosion-resistant elastic material. After the fasteners 34 are tightened, the squeezing force between the plate and the side wall of the square tube 11 will cause the sealing gasket 63 to undergo elastic deformation, thereby fully filling the tiny gap between the countersunk holes 62 and the side wall of the square tube 11, further improving the airtightness and waterproofness of the connection, and blocking the path of corrosive gases or liquids to penetrate from the connection gap.

[0032] In a preferred embodiment, see [reference] Figure 2 , 7 The frame 1 includes two symmetrically arranged side frames 12 and several connecting pipes 13 for connecting the two side frames 12. The two ends of the connecting pipes 13 are fixedly connected to the two side frames 12 by welding to form a stable overall structure of the frame 1. The side frames 12 are sequentially arranged with an inlet zone 121, a cooling zone 122, and a purification zone 123 along the gas flow direction of the desorption device. The heights of the inlet zone 121, cooling zone 122, and purification zone 123 gradually increase along the gas flow direction to accommodate the installation space requirements of different internal functional components. The position of the frame 1 corresponding to the cooling zone 122 is used to place the cooling device. 10. The cooling device 10 includes a surface cooler, which is used to efficiently cool the nitrogen carrying organic matter, so that the temperature of the organic matter in the nitrogen is reduced to below the saturation temperature, creating conditions for the precipitation of organic matter; the frame 1 is used to place the water-isolated plate 20, the electrostatic field 30 and the flow equalization plate 40 in sequence at the position corresponding to the purification zone 123. The water-isolated plate 20 is used to intercept the atomized droplets precipitated after cooling, so as to prevent the droplets from entering the subsequent structure and affecting the purification effect. The electrostatic field 30 is used to further adsorb fine droplets and trace impurities. The flow equalization plate 40 can make the nitrogen flow evenly distributed, ensuring that the purification process is stable and efficient, and finally achieving deep purification of nitrogen.

[0033] Two first side plates 2 are respectively installed on two side frames 12; one of the first side plates 2 has a first inspection port 21 corresponding to the position of the cooling zone 122, and a second inspection port 22 corresponding to the position of the purification zone 123; through these two inspection ports, the staff can easily install, disassemble, inspect and maintain the surface cooler in the cooling zone 122, the water baffle 20 in the purification zone 123, the electrostatic field 30 and the flow equalization plate 40 without disassembling the entire shell, thus improving equipment maintenance efficiency. The top plate assembly 4 is installed on the top of the two side frames 12, and the top plate assembly 4 has a first air inlet 41 corresponding to the position of the air inlet zone 121, and an air outlet 42 corresponding to the position of the purification zone 123; the second side plate 5 is installed on the front side of the two side frames 12, and has a second air inlet 51; the third side plate 6 is installed on the rear side of the two side frames 12. The first air inlet 41 and the second air inlet 51 can be flexibly selected as a single air inlet or a dual air inlet mode according to the actual working conditions; the air outlet 42 is used to discharge purified nitrogen.

[0034] Nitrogen gas carrying organic matter enters the intake zone 121 inside the shell through the first intake port 41 or the second intake port 51, and then flows sequentially through the cooling zone 122 and the purification zone 123 along the gas flow direction. After being cooled by the surface cooler in the cooling zone 122, the organic matter carried in the nitrogen gas reaches a saturated state and precipitates out to form droplets. Subsequently, the airflow enters the purification zone 123, where it passes through the water baffle 20 to intercept large droplets, the electrostatic field 30 to adsorb fine impurities, and the flow equalization plate 40 to evenly distribute the airflow, thus achieving the purification and regeneration of the nitrogen gas. Finally, the purified nitrogen gas is discharged from the outlet 42, completing the entire desorption process.

[0035] In the above implementation, please refer to Figure 1 , 2 7. The top plate assembly 4 also includes a first cover plate 43 and a second cover plate 44. Along the flue gas flow direction, the first air inlet 41, the first cover plate 43, the second cover plate 44 and the air outlet 42 are arranged in sequence. The first cover plate 43 is set corresponding to the air inlet area 121 of the frame 1. Its structure is adapted to the connection structure of the air inlet area 121 of the side frame 12. The first cover plate 43 is provided with an inclined section 431. The inclined section 431 is inclined upward along the gas flow direction away from the air inlet area 121, so that the internal flow channel corresponding to the air inlet area 121 has a gradually expanding structure, so that the airflow is evenly diffused to the surface of the surface cooler of the cooling area 122. The second cover plate 44 is set corresponding to the cooling area 122 of the frame 1. The air outlet 42 has a gradually narrowing structure, so that the airflow forms a concentrated flow stream before being discharged, reducing gas residue.

[0036] In a preferred embodiment, see [reference] Figure 2 , 4The base plate assembly 7 includes two guide plates 72, a connecting plate 73, and several reinforcing ribs 74. The two guide plates 72 are symmetrically arranged and inclined downwards. The connecting plate 73 is installed at the inclined lower end of the two guide plates 72 and has a drain port 75. The inclined arrangement of the guide plates 72 facilitates the cooling and precipitation of organic condensate, which converges along the surface of the guide plates 72 to the connecting plate 73 under gravity and is finally discharged from the drain port 75. Several reinforcing ribs 74 are arranged at intervals along the gas flow direction of the desorption device. The reinforcing ribs 74 are installed on the upper surface of the two guide plates 72 to improve the structural strength and stability of the base plate assembly 7. Specifically, the bottom of the reinforcing ribs 74 is provided with water passage holes 741, which are used to connect the flow channel between the guide plates 72 and the drain port 75 to ensure smooth discharge of organic condensate. The bottom of the frame 1 is provided with several spaced V-shaped support strips 14, which abut against the lower surfaces of the two guide plates 72. The cross-section of the V-shaped support strip 14 is "V" shaped, and its concave angle is adapted to the tilt angle of the guide plate 72, which can provide a stable support point for the guide plate 72.

[0037] Preferably, see Figure 2 , 4 The lower inclined end of the guide plate 72 is provided with a step portion 721. The connecting plate 73 is firmly bonded to the step portion 721 of the two guide plates 72 by adhesive to prevent leakage of organic condensate.

[0038] Furthermore, the guide plate 72 has a slotted hole on the side near the first side plate 2. The horizontal section of the first connecting piece 71 is fixedly connected to the upper surface of the guide plate 72, and its vertical section passes through the slotted hole and is connected to the connecting assembly 3 at the bottom of the frame 1. The first connecting piece 71 is also made of phenolic epoxy vinyl ester composite fiberboard, and its horizontal section is connected to the guide plate 72 by adhesive to ensure that the first connecting piece 71 and the guide plate 72 form a stable whole. The first connecting piece 71 is correspondingly connected to the connecting assembly 3 of the square tube 11 at the bottom of the frame 1. Combined with the support of the V-shaped support strip 14 at the bottom of the frame 1 for the guide plate 72, the bottom plate assembly 7 is stably installed at the inner bottom of the frame 1.

[0039] Furthermore, the bottom of the connecting plate 73 is provided with several downwardly extending second connecting pieces 731, which are fastened to the corresponding V-shaped support strips 14 by bolts. By increasing the fixed connection points between the base plate assembly 7 and the V-shaped support strips 14, the installation firmness of the base plate assembly 7 at the bottom of the frame 1 is further enhanced.

[0040] Please see Figure 8-10 The present invention also provides a method for assembling a desorption device housing, the assembly method being applied to the desorption device housing, the assembly method comprising: S101. Weld multiple square tubes 11 to form the frame 1; In this embodiment, each square tube 11 is cut and pre-processed with T-shaped holes 111 according to the processing design requirements of the frame 1, and then welded into the whole frame 1; subsequently, the V-shaped support strip 14 is fixedly connected to the square tube 11 at the bottom of the frame 1 by welding.

[0041] S102. Apply an anti-corrosion coating to the frame 1. In this embodiment, anti-corrosion coating is used to improve the corrosion resistance and service life of frame 1, ensuring structural stability and reliability even under complex working conditions. The coating material is a phenolic epoxy vinyl ester resin-based anti-corrosion coating, applied using a "three-layer cloth, five-coat" process to evenly cover the surface of frame 1 and weld areas, effectively blocking the erosion of moisture and organic condensate. The three-layer, five-coat process is an anti-corrosion and waterproof construction technique that enhances the corrosion resistance, waterproofness, and mechanical strength of the substrate by laying three layers of fiberglass cloth and applying five layers of anti-corrosion coating.

[0042] S103. Insert the multiple connecting components 3 into the T-shaped holes 111 of the square tube 11 accordingly; During installation, align the limiting plate 31 of the connecting component 3 with the horizontal section of the T-shaped hole 111 and push it into the square tube 11. Then, rotate the connecting post 32 so that the side wall of the square tube 11 engages with the gap between the spring piece 33 and the limiting plate 31. Under the elastic clamping force of the spring piece 33, the connecting component 3 and the square tube 11 form a stable pre-fixed structure, effectively preventing displacement during subsequent assembly. At the same time, the connecting post 32 slides into the vertical section of the T-shaped hole 111, and the end of the limiting plate 31 abuts against the bottom of the square tube 11, further improving the installation accuracy and stability of the connecting component 3 on the square tube 11. By pre-installing the connecting component 3, subsequent panel assembly only requires aligning the connecting post 32 for quick docking, effectively simplifying the on-site assembly process, reducing assembly errors, and improving overall installation efficiency.

[0043] S104. Install the base plate assembly 7 into the frame 1, and lock and fix the first connecting piece 71 to the connecting assembly 3 on the corresponding square tube 11. In this embodiment, two guide plates 72 are first placed on multiple V-shaped support strips 14 and pre-fixed to the corresponding connecting components 3 via first connecting pieces 71. Then, connecting plates 73 are installed on the inclined lower ends of the two guide plates 72 and firmly bonded to the stepped portions 721 of the guide plates 72 using adhesive. Finally, second connecting pieces 731 are bolted to the V-shaped support strips 14, and the first connecting pieces 71 are locked to the connecting components 3, achieving multi-point coordinated fixing between the base plate assembly 7 and the frame 1. By assembling the base plate assembly 7 in stages within the frame 1, the connection matching degree between the base plate assembly 7 and the bottom of the frame 1 is effectively improved, avoiding fitting gaps caused by pre-assembly deviations, while ensuring the structural integrity and sealing reliability of the base plate assembly 7.

[0044] S105. Install the two first side plates 2, the second side plate 5, the third side plate 6 and the top plate assembly 4 on the outside of the frame 1 in sequence, and lock them to the connecting assembly 3 on the corresponding square tube 11 respectively. In this embodiment, the pre-set mounting holes of each plate are matched with the connecting posts 32 of the connecting assembly 3 of the square tube 11, ensuring that the connecting posts 32 can be smoothly inserted. At the same time, the side of the plate facing the frame 1 has countersunk holes 62 that correspond one-to-one with the T-shaped holes 111 of the square tube 11. Before assembly, the sealing gaskets 63 are pre-installed in the edge grooves of the countersunk holes 62, so that the sealing gaskets 63 are tightly fitted to the inner wall of the countersunk holes 62. During installation, the plate is stably fitted to the corresponding mounting surface of the frame 1, and the position is adjusted so that the connecting posts 32 pass through the mounting holes of the plate. Then, the fasteners 34 are fitted onto the exposed end of the connecting posts 32 and tightened evenly. Under the locking force of the fasteners 34, the plate is firmly pressed against the side wall of the square tube 11, which not only achieves a stable connection and locking between each plate and the frame 1, but also causes the sealing gaskets 63 in the countersunk holes 62 to undergo elastic deformation, fully filling the tiny gap between the plate and the square tube 11, thereby achieving a tight fit and reliable seal between the plate and the square tube 11.

[0045] S106. Fill the joint gaps between adjacent panels with sealant; In this embodiment, by filling the splicing gaps between the first side plate 2 and the second side plate 5, the first side plate 2 and the third side plate 6, the top plate assembly 4 and the first side plate 2, the top plate assembly 4 and the second side plate 5, and the top plate assembly 4 and the third side plate 6 with sealant, the sealing reliability of the outer shell can be further improved.

[0046] The desorption device housing provided in this embodiment achieves a detachable connection between the plates and the frame 1 through the connecting component 3, forming a modular assembly structure for the housing. This effectively improves the convenience of maintenance and the flexibility of anti-corrosion treatment. When performing housing sealing inspection or anti-corrosion maintenance, there is no need to disassemble the entire housing. It can be operated flexibly according to maintenance needs. If anti-corrosion coating is required on the inner surface of the frame 1, only the surface cooler in the cooling zone 122, the water baffle 20 in the purification zone 123, the electrostatic field 30, and the flow equalization plate 40, etc., need to be removed. Then, the first side plate 2 on one side needs to be removed to directly apply anti-corrosion coating to the internal cavity of the frame 1. The operation is efficient and does not damage other structures. If deep anti-corrosion maintenance is required, all plates, including the first side plate 2, the second side plate 5, the third side plate 6, the top plate assembly 4, and the bottom plate assembly 7, can be completely removed to fully expose the frame 1. This facilitates comprehensive and thorough anti-corrosion treatment of the concealed areas, fundamentally improving the equipment's corrosion resistance.

[0047] Meanwhile, the connecting component 3 adopts a modular design, which is simple in structure and highly versatile. After its threaded structure wears and fails due to repeated disassembly and assembly, there is no need to replace the entire frame 1 or plate. Only the failed connecting component 3 needs to be replaced to restore the connection reliability. This not only reduces maintenance costs but also extends the overall service life of the housing, making it suitable for the long-term use of the desorption device under corrosive conditions.

[0048] In a preferred embodiment, see [reference] Figure 9 , 10 It also includes a support device 8 for assisting in supporting the first side plate 2 or the third side plate 6; the support device 8 includes: a trolley 81, a translation mechanism 82, a height adjustment component 84, a slide 85, and a suction cup assembly 86; the bottom of the trolley 81 is evenly distributed with four casters 811, two of which have a self-locking function to improve the stability of the trolley 81 in the placement state; the trolley 81 is provided with a handle 812 to facilitate the worker to push the trolley 81 to the installation position; the translation mechanism 82 is provided on the trolley 81, and the output end of the translation mechanism 82 is provided with an L-shaped movable frame 83 that translates in the horizontal direction; the height adjustment component 84 is slidably connected to the movable frame 83 in the vertical direction; the slide 85 is provided at the output end of the height adjustment component 84, and the height adjustment component 84 drives the slide 85 to move up and down; the suction cup assembly 86 is installed on the slide 85 for adsorbing and fixing the first side plate 2 or the third side plate 6; specifically, the suction cup assembly 86 includes four suction cups to achieve stable adsorption and fixing of the side plate.

[0049] During operation, the operator first places the first side panel 2 or the third side panel 6 to be installed stably on the pre-prepared anti-slip pad, ensuring the side panel is vertical and stably supported at the bottom. Then, the vacuum suction cup on the slide 85 is aligned with the side panel. The vacuum pump is activated, and the suction cup assembly 86 generates negative pressure to firmly fix the side panel. At this point, the anti-slip pad can be removed, and the support device 8 alone supports the weight of the side panel, effectively reducing the operator's handling burden. Next, the trolley 81 is pushed to move the side panel to the outside of the corresponding installation position on the frame 1. The L-shaped movable frame 83 is driven laterally by the translation mechanism 82 to adjust the lateral installation position of the side panel. Simultaneously, the height adjustment assembly 84 is operated to adjust the height of the slide 85, thereby adjusting the height installation position of the side panel so that all connecting posts 32 are aligned with the mounting holes of the side panel. Once the positioning is complete, the worker only needs to hold the fastener 34 and screw it into the connecting post 32 to lock and fix the side plate to the connecting component 3. During the locking process, the supporting device 8 continuously provides stable support to prevent the side plate from shifting due to gravity or locking force. After installation, the vacuum pump is turned off to release the suction cup's adsorption force, and the trolley 81 is pushed away from the workstation to complete a single auxiliary installation operation.

[0050] The support device 8 can effectively assist workers in lifting and stabilizing the heavier first side plate 2 and third side plate 6, reducing the labor intensity of manually supporting the plates during side plate installation; at the same time, it eliminates the need for multiple people to assist, saving labor costs and improving assembly efficiency.

[0051] In a preferred embodiment, see [reference] Figure 9 , 10 The translation mechanism 82 includes a first lead screw transmission assembly 821 and a guide rail 822. Two parallel guide rails 822 are fixed on the trolley 81. The movable frame 83 is slidably connected to the guide rails 822. The trolley 81 is connected to the movable frame 83 through the first lead screw transmission assembly 821. The input end of the first lead screw transmission assembly 821 is provided with a first handwheel 823. Rotating the first handwheel 823 can drive the movable frame 83 to move horizontally along the guide rails 822, thereby realizing the lateral position adjustment of the side plate.

[0052] In a preferred embodiment, see [reference] Figure 9 , 10 The movable frame 83 is provided with two vertically arranged first guide rods 831; the height adjustment component 84 includes a movable seat 841, which slides in conjunction with the first guide rods 831; the movable frame 83 is provided with a plurality of positioning holes 832 arranged at intervals along the vertical direction, and a hand screw 842 is screwed onto the movable seat 841. The hand screw 842 can be inserted into any positioning hole 832 to position the movable seat 841, thereby fixing the height position of the slide 85; by adjusting the hand screw 842 to lock in the positioning holes 832 at different heights, the height of the slide 85 can be coarsely adjusted to match the initial height of the suction cup component 86, so that it matches the preset suction fixing position of the side plate to be installed.

[0053] Further, see Figure 9 , 10 The height adjustment component 84 also includes a second guide rod 843 and a second lead screw transmission component 844. The two second guide rods 843 are vertically fixed on the movable seat 841. The slide 85 is slidably connected to the second guide rods 843. The slide 85 is connected to the movable seat 841 through the second lead screw transmission component 844. The input end of the second lead screw transmission component 844 is provided with a second handwheel 845. Rotating the second handwheel 845 can drive the slide 85 to rise and fall vertically along the second guide rods 843, thereby realizing the fine adjustment of the installation height of the side plate, ensuring that the mounting holes on the side plate are aligned with the connecting posts 32 of the corresponding connecting components 3 of the frame 1, and improving assembly accuracy and efficiency.
