Description

Technical Field

[0001] The present invention relates to the field of dry paint mist filtration for automobiles, parts and general industrial spraying equipment, and in particular to an automatic side pressing and sealing structure for a dry filter box. Background Art

[0002] In the field of dry paint mist filtration in spray production lines, the dry paint mist filter box that absorbs overspray paint mist needs to be replaced regularly, and needs to be loaded, positioned, fixed, moved and replaced through the dry filter module. At the same time, the joints between the dry paint mist filter box and the dry filter module need to be locked, pressed and sealed to prevent paint mist from overflowing and polluting the workshop, or paint residue sticking to the joints and being difficult to remove and affect replacement, or air leakage at the seals affecting the balance of the circulating air in the spray room and thus affecting the product qualification rate.

[0003] The most critical and challenging aspect of dry paint mist filtration technology is sealing the joints, especially for dry filter boxes with top and bottom ventilation, which require simultaneous sealing in three axes and horizontal movement. The dry filter box slides horizontally, leaving gaps between the top and bottom. Seals are applied from top to bottom, the front is pushed forward to lock, and the sides are compressed inward. This requires dynamic movement and sliding under load to achieve sealing while also preventing the dry filter box from getting stuck during initial advancement, and ensuring the locking mechanism clears the dry filter box's path. Achieving all of these functions simultaneously is extremely challenging.

[0004] The existing similar technologies have dry paint mist collection boxes with upper opening, side opening and bottom box plates. The common original general practice is: 2 groups of front-facing forward-pushing cylinders with flipping clamps flip together to press the dry filter box forward and lock it as a whole; 1 group of upper-facing forward-pushing cylinders with flipping pressing plates flip together to press the upper positive extension edge of the dry filter box; 2 groups of side cylinders with flat pressing plates push straight to press the sides of the dry filter box.

[0005] The main problems of existing similar technologies are summarized as follows: 1. Each set of five cylinders in different locations within the same dry filter box utilizes the same air source, mechanical switches, and simultaneous activation. However, due to varying air pipe lengths, cylinder structures, strokes, thrust forces, and diameters, the cylinders drive the tilting fixture or the flipping clamp differently, leading to different radii and paths. Direct push on the flat clamp is the fastest, resulting in significant differences in the time it takes to lock into place, leading to asynchronous locking and, in turn, partial inability to lock into place. In particular, direct push on the side cylinders can cause the front to lock into place first, preventing further advancement and causing air leakage. This presents a significant problem with all existing technologies.

[0006] 2. The side push cylinder is located at the center of the length direction of the flat clamping plate. One force application point of the cylinder in the length direction can easily lead to uneven force at both ends of the clamping plate.

[0007] 3. Longitudinal vertical sealing plates are designed on both sides of the upper air inlet dry filter module, and the longitudinal pressure plate of the cylinder pushes horizontally to press and seal. The passage for the forward and backward movement of the dry filter box needs to be avoided between the two left and right opposite vertical sealing plates. For this reason, the horizontal spacing between the opposite vertical sealing plates must be greater than the width of the dry filter box and leave sufficient gap to ensure smooth passage. Large gaps on both sides can easily lead to inaccurate left and right positioning of the dry filter box and a high risk of air leakage.

[0008] 4. The space for side locking is narrow and difficult to operate: The distance between two adjacent dry filter modules in the length direction of a large double-sided robot spray booth is 300-400mm. Generally, due to the modular design, processing, installation, and overseas transportation matching container size of the dry spray booth, they are designed to be 2 meters or 3 meters as a modular module design; the space for arranging the side compression sealing structure of the dry filter box is limited, and it is inconvenient for personnel to operate or maintain in the narrow space on the side. Therefore, it is necessary for the equipment to occupy a small space and operate stably and reliably.

[0009] 5. Each dry filter box is equipped with 5 groups of cylinders, including 2 groups on the side. The large number of cylinders increases equipment investment. A car body line has about 120 sets of dry filter modules, and 5 groups have a total of 600 sets of cylinders. If the cylinder leaks, the impact and wasted air source cost will be very large.

[0010] 6. In order to improve the strength of the side longitudinal compression plate, the overall structure occupies a large space.

[0011] 7. The space for side compression is small and difficult to operate: The distance between two adjacent dry filter modules in the length direction of a large double-sided robot spray booth is 300-400mm. Generally, due to the modular design, processing, installation and overseas transportation matching container size of the dry spray booth, they are designed as a modular module design of 2 meters or 3 meters. The space for arranging the side compression sealing structure is small, which makes it inconvenient for maintenance personnel to operate. Therefore, it is necessary for the equipment to occupy a small space, operate stably and reliably, and be easy to operate.

[0012] As mentioned above, the structural form, locking stability and reliability, locking effect, sealing effect, investment cost, etc. of the front locking and sealing device of the dry paint mist filter module and the dry paint mist filter box in the existing technology need to be further optimized and improved. Summary of the Invention

[0013] The purpose of the present invention is to provide an automatic compression and sealing structure for the side of a dry filter box to solve the difficulties and pain points in the prior art. A solution for the automatic compression and sealing structure for the side of a dry filter box is proposed, which is integrated with the upper and lower ventilated dry filter box, the upper air inlet dry filter module and the sealing plate structure, the lower air outlet dry filter module and the guide positioning wheel, the frame sealing structure and the sealing strip, the front automatic locking sealing device and the power component to realize the automatic compression and sealing of the side of the dry filter box, so as to achieve good sealing effect, high compression strength, simple and practical structure, reliable and stable, low investment cost, small space occupation, and convenient operation.

[0014] The above technical objectives of the present invention are achieved through the following technical solutions.

[0015] A dry filter box side automatic compression sealing structure, comprising: a compression device, an eccentric compression assembly, a pushing structure, a bearing support member, and a power assembly; The pressing device comprises a pressing rod, a double-layer fixing member for the pressing rod, and a pressing rod reinforcement plate; the pressing rod reinforcement plate is firmly connected to the pressing rod; The pressing rod can rotate horizontally within the height range of the double-layer fixing member of the pressing rod; The eccentric pressing assembly includes an eccentric wheel, a limiter, an eccentric fixing part, and a rotating part.

[0016] It is understandable that The power assembly drives the pushing structure to push the eccentric wheel to rotate forward, and then the eccentric wheel gradually applies force and directly squeezes the clamping rod, or directly squeezes the clamping rod reinforcement plate and then synchronously and indirectly squeezes the clamping rod, and the clamping rod reinforcement plate is firmly connected to the clamping rod; the clamping rod can be tightly attached to the side of the dry filter box as a whole; combined with the clamping rod being able to rotate in the horizontal direction to realize the opening and closing function, the open state avoids the channel, and the closed state presses the side of the dry filter box; the side automatic clamping sealing structure finally realizes the compression seal of the upper side extension edge of the dry filter box and the inclined structure of the side of the upper air inlet dry filter module and the second elastic seal.

[0017] Preferably, The pressing rod is an integral structure; The pressing rod at least comprises a long section, a short section and an arc-shaped connecting surface; The long segment and the short segment are connected at an acute angle.

[0018] It is understandable that The short section of the pressing rod is provided with a pressing rod rotation point, which is connected to the double-layer fixing member of the pressing rod; The pressing rod can rotate in the horizontal direction with the pressing rod rotation point as the axis to realize the opening and pressing functions of the pressing rod; The rotation point of the pressure rod is designed as a rotation hole or a rotation axis; The double-layer fixing piece of the pressure rod is connected and fixed to the rotation hole or the rotation axis of the rotation point of the pressure rod; The long section is completely fitted with the dry filter box, and the short section is used for rotational connection and fixation.

[0019] During the switching between the opening and the clamping state, the long section can avoid interference with surrounding structural parts during the entire dynamic rotation of the clamping rod because the outer portion of the arc-shaped connecting surface is in a contracted form; at the same time, it can avoid obstruction during the advancement or removal of the dry filter box.

[0020] The long section and the short section are connected at an acute angle, and the first pressing point of the long section is pressed to the front end of the upper extension edge of the dry filter box as much as possible; secondly, the ends of the long section are opened at the same distance, and the rotation angle of the pressing rod is minimized.

[0021] When the pressing rod is in the open state, the short section and the automatic side pressing sealing structure of the opposite dry filter box do not interfere with each other, and it can be ensured as much as possible that the first pressing point can be pressed to the forefront of the upper extended edge of the dry filter box.

[0022] When the clamping rod is in a clamped state, the arc-shaped connecting surface connecting the short section and the long section can be crimped and sealed with the forefront of the upper extended edge of the dry filter box, thereby avoiding a blind spot in the clamping of the dry filter box due to the curved space of the arc-shaped connection.

[0023] The clamping rod needs to avoid the passage of the dry filter box; for this purpose, during the movement of the dry filter box in and out, the clamping rod is in an open state; conversely, after the dry filter box is pushed into place, the clamping rod is in a clamped state.

[0024] When opening, the end of the long section of the pressing rod rotates in the opposite direction of the dry filter box, and the end of the long section of the pressing rod is farthest from the dry filter box; conversely, when tightening, the end of the long section of the pressing rod rotates toward the direction of the dry filter box, and the long section of the pressing rod is pressed parallel to the side of the dry filter box.

[0025] The double-layered fixing for the compression rod has two upper and lower flat panels, double-sided openings, and a rotating structure. The lower panel supports the short section of the compression rod to prevent it from falling, while the upper panel limits the horizontal rotation of the compression rod to prevent it from swinging in the vertical direction. The double-layered flat panels also connect to the fixing for the rotational position, while the double-sided openings allow the short section of the compression rod and the arc-shaped connecting surface to pass through and connect.

[0026] Preferably, The dry filter box comprises a side upper frame and an upper extension edge; The pressing rod presses the side upper frame or the upper extension edge of the dry filter box; the pressing rod fits and presses the upper extension edge, and the upper extension edge is deformed after being pressed, and is pressed and sealed more tightly with the side of the upper air inlet dry filter module.

[0027] It is understandable that The pressing rod presses the upper extension edge, which can cause the upper extension edge to produce a certain deformation, so that the pressing rod can press deeper and tighter, thereby strengthening the seal with the side of the upper air inlet dry filter module.

[0028] The upper extension edge is deformed after being compressed. At the same time, combined with the inclined structure of the upper air inlet dry filter module, there is no resistance during the advancement of the dry filter box. The second elastic seal connected to the inclined structure overlaps with the upper extension edge. The upper extension edge of the dry filter box is already in a sealed state during the sliding process. Combined with the compression of the compression rod on the side, the compression seal is further strengthened.

[0029] The compression line overlaps the second elastic seal of the upper air inlet dry-type filter module at the same horizontal plane and is compressed under the action of external force to compress the elasticity of the second elastic seal to achieve sealing.

[0030] Preferably, The long section of the pressing rod is provided with a first pressing point for pressing the dry filter box; The first pressing point is close to the short segment; The length from the first pressing point to the end of the long section is greater than the side length of the dry filter box, ensuring that the side of the dry filter box is pressed as a whole.

[0031] It is understandable that The pressing rod and the dry filter box are pushed forward almost in parallel without interfering with each other, especially at the position of the first pressing point, the passability is not affected, and the fit is tight; the first pressing point and the upper extension edge of the dry filter box are in a non-pressed state during the pushing process, and they can naturally slide to fit and overlap for a preliminary seal; after being pushed into place, they are compressed more tightly under the action of the automatic side pressing and sealing structure.

[0032] The position of the first pressing point can completely press the front end of the dry filter box to avoid a blind area of ​​pressing.

[0033] Preferably, The pressing rod is provided with a direct pressing position in the long section; The direct pressing position is set at a certain point or a certain area of ​​the long section.

[0034] It is understandable that The direct pressing position is designed to be the specific position where the eccentric wheel presses the pressing rod; The direct pressing position may also be designed as the area where the eccentric wheel presses the pressure rod reinforcement plate.

[0035] Preferably, With the direct pressing position as the center, the long section of the pressing rod is provided with single sections on both sides; or: with the direct pressing position as the starting point, the long section of the pressing rod is provided with single sections towards the end of the long section.

[0036] It is understandable that The long section is provided with a single section with an inclined angle, and its main function is to strengthen the pressure toward the distal end of the long section during the clamping process of the clamping rod, in addition to the maximum force at the direct clamping position, to ensure that the distal end of the long section can be clamped more firmly.

[0037] Preferably, One or more of the single segments have an inclined angle; A single section of the pressing rod or adjacent single sections are close to one side of the dry filter box, forming an obtuse angle.

[0038] It is understandable that With the direct pressing position as the center, the long section of the pressing rod is provided with single sections on both sides, and is provided with an obtuse angle. During the pressing process of the eccentric wheel, the certain elasticity of the pressing rod is utilized to flatten the obtuse angle into a straight line, and the distal end of the single section is pressed tighter. After the obtuse angle is flattened into a straight line, the direct pressing position is prevented from being pressed deeper and more protruding, causing uneven force on the pressing rod.

[0039] The single section of the long section end of the pressing rod and the main body of the long section form an obtuse angle on one side close to the dry filter box; that is, the end of the long section is overlapped with the dry filter box in advance, and after the direct pressing position is pressurized, the end of the long section applies greater force to the dry filter box and presses it tighter.

[0040] The first pressing point is pressed, and the lever principle of the pressing rod is utilized to set a second pressing position, namely the direct pressing position, in the long section of the pressing rod. When the direct pressing position is pressed, the first pressing point will be pressed tighter. Combined with the inclination angle of the single section of the pressing rod in the long section, the long section is driven to be closer to the side of the dry filter box under the dual action, thereby ensuring a better overall pressing effect of the pressing rod.

[0041] The inclination angle of the single section is designed as a whole according to the width or depth of the dry filter box, the distance of the direct pressing position, the distance between the ends of the long section, and the pressing force of the side automatic pressing sealing structure.

[0042] Preferably, The eccentric wheel is a cylindrical body with a cross-sectional area; The height of the eccentric wheel is adapted to the height of the pressing rod; The cross-sectional area of ​​the eccentric wheel is circular or arc-shaped as a whole; Or: the cross-sectional area of ​​the eccentric wheel is partially circular or arc-shaped.

[0043] It is understandable that The eccentric wheel is a cylindrical solid structure with sufficient strength; and the eccentric wheel rotates continuously during the compression process, and the overlap area or stroke distance with the compression rod or the compression rod reinforcement plate is designed with a certain redundancy, and the installation position of the eccentric wheel in the front and rear directions can be adjusted; the cross-sectional area of ​​the eccentric wheel is designed to be circular or arc-shaped, and the continuous force application is more stable and reliable; the height of the eccentric wheel covers the height of the compression rod as a whole, the force application area is large, and the force application is more uniform.

[0044] Preferably, The eccentric pressing assembly includes an eccentric fixing member; The eccentric fixing member includes an adjustable hole and a limiter; The eccentric wheel is provided with a rotation position.

[0045] It is understandable that The rotating position is used for the eccentric wheel to rotate; The rotation position is designed as an axial connection; The eccentric pressing assembly is provided with an eccentric fixing member; The rotation position is arranged in the cross section of the eccentric wheel close to the pressing rod; An adjustable hole is provided at the connection position between the eccentric fixing member and the bearing support member, and the adjustable hole is used to adjust the front and rear positioning of the eccentric wheel; A limiter is provided on the periphery of the eccentric fixing member to prevent the eccentric wheel from rotating beyond the limit; The eccentric fixing member is provided with a lower plane plate for supporting the pressing rod, ensuring that the pressing rod rotates at the same height in the horizontal plane and the long end of the pressing rod does not droop.

[0046] Preferably, The pushing structure is connected to the power assembly; The pushing structure is provided with an inclined pushing plate; The inclined push plate has an inclined surface; The inclined surface and the long section of the pressing rod are overlapped to form an acute angle; The surface area of ​​the inclined surface is sufficient to cover the outer surface of the eccentric wheel that is in rotational contact with the eccentric wheel, and a redundancy is provided.

[0047] It is understandable that Under the action of the forward driving force of the power assembly, the inclined push plate overlaps with the eccentric wheel and presses the pressing rod; conversely, after the inclined push plate retreats, the eccentric wheel is separated from the pressing rod.

[0048] Preferably, The bearing support member includes a tensioning member and a bearing plate; The other end of the tensioning member is connected to the long section of the pressing rod close to the end; The tensioning member is elastic.

[0049] It is understandable that The bearing support is used to bear and fix the power assembly, the pressing device, the eccentric pressing assembly, the pushing structure, the tensioning member, etc.; One end of the tensioning member is fixed to the load-bearing support member, and the other end is connected to the pressing rod; The tensioning member is used to rotate the end of the long section of the pressing rod outward to open it through the elastic tension of the tensioning member, and completely avoid the passage of the dry filter box when the pressing rod is in the open state.

[0050] Preferably, A method for using a dry filter box side automatic compression sealing structure, The process of the pushing structure moving forward straightly includes at least an unloaded section and a loaded section; The no-load stage is the stage before the front face of the dry filter box is pushed forward and locked into place; that is, the inclined push plate does not substantially press the eccentric wheel; The load section is the stage in which the front of the dry filter box is pushed forward and locked in place before being pressed sideways; that is, the inclined push plate is pushed forward but does not contact the eccentric wheel, and the eccentric wheel substantially presses the pressing rod.

[0051] The load compression stage of the side automatic compression sealing structure is designed to be at the end of the forward thrust stroke of the power component.

[0052] It is understandable that After the front of the dry filter box is locked forward, the inclined push plate begins to press the eccentric wheel and further presses and seals the side of the dry filter box within the range of the power assembly's forward movement. Before the automatic dry filter box is pushed forward and locked in place, the inclined push plate is running in a no-load state and does not overlap the eccentric wheel; The power assembly is designed with at least two operations within the entire forward thrust range, one is front locking of the dry filter box, and the other is side pressing; the side pressing is further tightened on the premise that the front locking is completed.

[0053] The side automatic compression sealing structure is designed at the end of the straight forward pushing stroke of the power component to ensure that the side compression is performed after the front locking of the dry filter box is completed, and both the front and side can be locked in place in the end.

[0054] Preferably, The power component adopts a linear power direction; it uses the horizontal forward driving force to convert it into a driving force to the left and right sides in the same horizontal plane, thereby pushing the pressing rod to press the dry filter box.

[0055] It is understandable that The power assembly can be powered by a cylinder, a motor, etc. Adopting direct push cylinder, using forward thrust as power source, it has better stability; A power assembly may be provided separately, or the power source of the front automatic locking sealing device may be utilized.

[0056] A linear cylinder that pushes forward and backward is used, and there is no loss of forward thrust. There is no need for the cylinder to flip or the air pipe to flip with the locking flip action. The cylinder body is fixed and the air pipe connected to the cylinder is also fixed. There is no risk of leakage due to the dynamic influence of the flip.

[0057] After the forward-pushing cylinder is fixed, except for the cylinder pushing shaft, the main body is in a fixed state and is not affected by the power of the cylinder moving forward. It has good stability and there is almost no error and deviation in the cylinder pushing process. There will be no problems of cylinder loosening or air pipe leakage.

[0058] Preferably, Each pressing surface overlapping the pressing rod is configured with at least one combination of a pressing device and an eccentric pressing assembly.

[0059] In summary, the main key points and beneficial effects of the technical solution of the present invention are summarized as follows.

[0060] 1. The pushing structure is designed to push forward in a straight line. Two functional sections are designed: the no-load section and the loaded section. The no-load section is first locked from the front, and the loaded section is further tightened from the side to ensure that both the front and side of the dry filter box can be locked in place and improve the sealing effect.

[0061] 2. Through the spacing design of the eccentric pressing assembly and the inclined push plate of the pushing structure, the delayed side pressing is controlled to ensure that the front locking is fully in place and improve the locking and sealing effect.

[0062] 3. A horizontally rotatable clamping rod is used. By utilizing the lever principle of the clamping rod, force is applied to the clamping rod at multiple points through the first clamping point, direct clamping position, optional connection of the clamping rod reinforcement plate, and single-section inclination angle of the long section of the clamping rod. This achieves better compression and sealing effects throughout the entire length of the clamping rod.

[0063] 4. The compression rod is a tubular part, which overlaps with the upper extension edge of the dry filter box to form a compression line. The compression line is subjected to the greatest pressure. The compression rod directly compresses the upper extension edge and then indirectly compresses the second elastic seal. After the second elastic seal produces compression deformation, it effectively strengthens the seal.

[0064] 5. The horizontal pressing line of the pressing rod can be selected to correspond to the connection line between the frame of the dry filter box and the upper extension edge within the height range; this design can not only press the main frame of the dry filter box for positioning, but also press the upper extension edge of the dry filter box for sealing.

[0065] 6. The eccentric wheel directly squeezes the compression rod or indirectly squeezes the compression rod through the compression rod reinforcement plate. The overall extrusion force is uniform and strong, and the operation is smooth. The extrusion position, distance, and angle are adjustable, which can perform precise compression. There is a large dimensional tolerance for dry filter module equipment, which avoids installation errors affecting the compression effect.

[0066] 7. In the open state, the elastic tensioning piece drives the long end of the clamping rod to rotate horizontally outward to avoid the passage, which facilitates the smooth passage of the dry filter box replacement process.

[0067] 8. The double-layer plate design of the double-layer fixing of the compression rod has a limiting effect. The compression rod will not swing up and down in the same horizontal direction and always maintains a horizontal state. The stability between the connecting parts is good, ensuring that the compression line is horizontal.

[0068] 9. The eccentric wheel limiter prevents the eccentric wheel from getting stuck due to the extreme position operation.

[0069] 10. The front propulsion component of the shared front automatic locking sealing device eliminates the power component, reducing investment costs and maintenance costs.

[0070] Compared with the problems of the prior art, the technical features and beneficial effects of the present invention are described one by one as follows.

[0071] 1. The power assembly of the shared front automatic locking and sealing device is simple and practical with stable performance.

[0072] 2. The adjacent sides of the two adjacent dry filter boxes in the length direction of the spray room adopt the same set of side automatic compression sealing structure. The symmetrical arrangement is stable, and the force is evenly applied to the opposite sides, which reduces the investment cost of one set; one set of control is simple to operate.

[0073] 3. The prior art uses a longitudinal compression plate to apply pressure to the longitudinal vertical sealing plate; the present invention adopts a compression rod for linear compression, which minimizes the compression area and has a greater compression strength; combined with the inclined structure of the side sealing plate of the upper air inlet dry filter module and the second elastic seal, the upper side extension of the dry filter box slides in a zero-gap overlap with the second elastic seal in an elastic compression state; on the premise of achieving the first side seal, a second reinforced compression seal is added to achieve a better sealing effect.

[0074] 4. The upper extension edge of the dry filter box is almost parallel to the clamping rod, and the dry filter box has little resistance when pushed forward. Even when it reaches the first clamping point, it can pass through almost without resistance when the clamping rod is rotated and opened. The clamping rod is locked to ensure tighter compression.

[0075] 5. Make full use of the width direction of the frame sealing structure to arrange the short section of the clamping rod, ensure that the first clamping point of the long section of the clamping rod is attached to the upper extension edge of the dry filter box, avoid the appearance of a clamping blind area at the forefront of the upper extension edge of the dry filter box on the curved connection surface of the clamping rod, and achieve comprehensive clamping and sealing of the upper extension edge.

[0076] 6. The overall side automatic compression sealing structure and overall modular design and installation are more efficient, precise installation, easy operation, and take up less space. Redundancy of the connection is reserved within the error range that may be caused by the surrounding connected equipment, which can be accurately adjusted.

[0077] 7. The side compression sealing structure of the dry filter box needs to be completed in combination with the upper air inlet dry filter module, the lower air outlet dry filter module, the frame sealing structure, and the front automatic locking sealing device. It is a systematic solution that works together and is indispensable.

[0078] From the above review, the side automatic compression sealing structure has obvious advantages in terms of compression effect, locking stability and reliability, overall comprehensive compression, equipment investment cost, small space occupation, degree of automation, operation convenience, mutual cooperation of peripheral equipment, subsequent maintenance, advancement smoothness, operation stability, and reliability.

[0086] The eccentric pressing assembly 2 includes an eccentric wheel 21 , a limiter 22 , an eccentric fixing member 23 , and a rotating member 24 .

[0087] Example 1, refer to the attached Figure 1 , The pressure rod reinforcement plate 13 is designed as a U-shaped groove structure and is welded and fixed to the pressure rod 11; the U-shaped groove structure is provided with a longitudinal surface for overlapping and pressing the side surface of the eccentric wheel 21 with the longitudinal surface.

[0088] The double-layer fixing member 12 of the pressure rod has two upper and lower flat plates. The bottom flat plate is used to support the clamping rod 11, and the upper flat plate is used to limit the rotation of the clamping rod 11 in the horizontal plane; the limit 22 of the eccentric clamping assembly 2 prevents the eccentric wheel 21 from rotating too much in the open state and getting stuck after reaching the limit and being unable to rotate again.

[0089] The eccentric fixing part 23 is designed with front and rear slots, and is connected and fixed to the opening of the load-bearing support part 4 by a bolt assembly; the installation position of the eccentric fixing part 23 can be adjusted front and back, thereby accurately controlling the front and rear positions of the eccentric wheel 21 squeezing the clamping rod 11 or the clamping rod reinforcement plate 13, realizing the initial contact position of the inclined surface 32 of the inclined push plate 31 of the pushing structure 3 with the eccentric wheel 21, the specific clamping position and the displacement distance of the side clamping, thereby determining the clamping strength of the clamping rod 11.

[0090] The rotating position 24 is connected to the double-layer fixing member 12 of the pressure rod through a pin, so as to realize the rotation of the clamping rod 11 in the horizontal direction; the end of the long section 112 of the clamping rod 11 is rotated outward to open, and rotated inward to clamp; in the open state, the passage of the dry filter box 8 is avoided, and in the clamped state, the second elastic seal 101 arranged on the inclined structure 111 on the side of the upper air inlet dry filter module 100 is compressed and sealed with the upper extension edge 81 of the dry filter box 8.

[0091] The side automatic compression sealing structure 40, the power component 5 drives the eccentric wheel 21 of the eccentric compression assembly 2 to compress the compression rod 11 of the compression device 1 through the pushing structure 3. The compression rod 11 is tightly attached to the dry filter box, and the eccentric wheel 21 is forced to gradually rotate in the process of synchronously applying force to the compression rod 11, finally achieving the side compression sealing effect of the dry filter module 100 on the air inlet of the dry filter box 8.

[0092] Further, The pressing rod 11 is an integral structure; it is made of a whole bent pipe; The pressing rod 11 comprises a long section 112, a short section 113, and an arc-shaped connecting surface 114; the arc-shaped connecting surface is contracted on the outside; The long section 112 and the short section 113 are connected at an acute angle.

[0093] Example 2, refer to the attached Figure 1 , Attachment Figure 8 , The short section 113 of the clamping rod 11 is provided with a clamping rod rotation point 115, which is connected to the clamping rod double-layer fixing piece 12 through the clamping rod rotation point 115; the clamping rod 11 can rotate in the horizontal direction with the clamping rod rotation point 115 as the axis, thereby realizing the opening and clamping functions of the clamping rod 11; a rotation hole is designed at the clamping rod rotation point 115, and the rotation hole of the clamping rod double-layer fixing piece 12 and the clamping rod rotation point 115 are connected by a pin.

[0094] When the long section 112 switches between the open state and the compressed state, the arc-shaped connecting surface 114 does not interfere with the surrounding structural components during the dynamic rotation process.

[0095] The clamping rod 11 needs to avoid the passage of the dry filter box 8; during the operation of moving the dry filter box 8 in and out, the clamping rod 11 is in the open state; conversely, after the dry filter box 8 is pushed into place, the clamping rod 11 is in the clamping state.

[0096] When opening, the end of the long section 112 of the pressing rod 11 is pulled away in the opposite direction parallel to the dry filter box 8 with the pressing rod rotation point 115 as the axis, and the end of the long section 112 of the pressing rod 11 is farthest from the dry filter box 8.

[0097] On the contrary, when pressing, the end of the long section 112 of the pressing rod 11 is pulled parallel to the dry filter box 8 and pressed against the dry filter box 8 with the pressing rod rotation point 115 as the axis, and the long section 112 of the pressing rod 11 is pressed parallel to the dry filter box 8.

[0098] The pressure rod rotation point 115 is provided with a penetrating circular hole in the straight section of the short section 113, which is connected by an axis, a pin, etc.; the pressure rod double-layer fixing part 12 has a double-layer plane plate, double-sided openings and a rotation structure; the lower layer of the double-layer plane is used to carry the clamping rod 11, and the upper layer is used to limit the height direction of the clamping rod 11 when it rotates in the horizontal direction, to prevent the clamping rod from swinging arbitrarily in the height direction; the double-layer plane plate is also used to firmly fix the clamping rod 11; the double-sided opening is used for the short section 113 of the clamping rod 11 and the arc-shaped connecting surface 114 to pass through and connect.

[0099] Further, The dry filter box 8 comprises a side upper frame 83 and an upper extension edge 81; The pressing rod 11 presses the upper side extension 81 of the side of the dry filter box 8 to form a pressing straight line 84; The pressing line 84 is designed to be the joint between the side upper frame 83 and the upper extension edge 81 or close to the upper extension edge 81; The pressing rod 11 is pressed against the upper extension edge 81 , which can cause a certain deformation of the upper extension edge 81 , so that the pressing rod 11 can press deeper and tighter.

[0100] Example 3, refer to the attached Figure 1 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 11 , At the same time, combined with the inclined structure 111 of the upper air inlet dry filter module 100, the dry filter box 8 slides almost without resistance during the advancement process. The second elastic seal 101 connected to the inclined structure 111 overlaps with the upper extension edge 81. The upper extension edge 81 of the dry filter box 8 is already in a sealed state during the sliding process. After it is in place, it is combined with the compression of the side clamping rod 11 to further strengthen the compression.

[0101] Further, The long section 112 of the pressing rod 11 is provided with a first pressing point 116 for pressing the dry filter box 8; The first compression point 116 is close to the short section; The length from the first pressing point 116 to the end of the long section 112 is greater than the side length of the dry filter box 8 , ensuring that the side of the dry filter box 8 is pressed as a whole.

[0102] Example 4, refer to the attached Figure 1 , Attachment Figure 8 , Before the dry filter box 8 is prepared to be pushed forward, the clamping rod 11 is in the open state, and there is a very small separation angle and spacing between the clamping rod 11 and the upper extension edge 81 of the dry filter box 8. The separation angle is within about 2-3°, which can achieve a distance of more than 30mm between the end of the long section 112 of the clamping rod 11 and the forefront 82 of the upper extension edge 81 of the dry filter box 8; under the guidance of the guide wheel of the lower air outlet dry filter module 200, the error of the left and right deviation of the dry filter box 8 after it is pushed and in place does not exceed 3mm on one side. Therefore, even a rotation angle of 1° can achieve the clamping rod 11 to completely avoid the channel, ensuring the smooth passage of the dry filter box 8.

[0103] The upper extension edge 81 of the dry filter box 8 is offset from the clamping rod 11 at an angle of 1-2°, which is almost parallel. In the forward direction, the dry filter box 8 will no longer be stuck by the clamping rod 11 as long as it enters the area of ​​the clamping rod 11. Even if the two reach the first clamping point 116, the resistance is almost very small, which can ensure that the upper extension edge 82 and the leading edge 82 of the dry filter box 8 can be pushed into place.

[0104] Even if there is a certain amount of resistance, it is achieved by pressing the second elastic seal 101 of the upper air inlet dry filter module 100, combining the upper extended edge 81 of the dry filter box 8 with the second elastic seal 101 for sliding overlap, and utilizing the smooth material of the outer box body of the dry filter box 8 to slide smoothly when overlapping with the second elastic seal 101; in this way, both effective sealing and smooth sliding can be achieved.

[0105] To this end, the distance between the first pressing point 116 of the pressing rod 11 and the dry filter box 8 is reduced by a few millimeters, which can ensure that the first pressing point 116 and the dry filter box 8 fit tightly in a natural state, and then under the external force of the side automatic pressing sealing structure 40, the pressure will become tighter and tighter.

[0106] When the dry filter box 8 is in its natural state and not compressed and opened, the first compression point 116 is at a distance from the side outer box body of the dry filter box 8. After the dry filter box 8 has been pushed to the upper air inlet dry filter module 100 and is in place, the forefront 82 of the upper extension edge 81 of the dry filter box 8 is in place, and the arc-shaped connecting surface 114 or the first compression point 116 of the compression rod 11 has been forced to compress the upper extension edge 81 of the dry filter box 8. The first compression point of the compression rod 11 is more firmly and tightly compressed after the compression rod 11 is subjected to force. When in the open state, the dry filter box 8 can be smoothly moved out. Before the dry filter box 8 is pushed in again, the compression rod 11 is opened in advance to ensure that the dry filter box 8 is smoothly pushed into place.

[0107] Through the first pressing point 116 of the rotatable pressing rod 11 and the adjustable eccentric wheel 21, force is applied indirectly or directly in the length area extending to both sides of the direct pressing position 118 of the pressing rod 11, and then combined with the single section 117 of the bevel angle at the end of the long section 112 of the pressing rod 11 to strengthen the force. The three jointly apply force to different areas of the pressing rod 11 and the adapted pressure size, and drive the inclined push plate 31 of the pushing structure 3 to press the eccentric wheel 21 under the original driving force of the power component 5, thereby jointly realizing the side compression and sealing of the dry filter box 8.

[0108] Further, The pressing rod 11 is provided with a direct pressing position 118 at the long section 112; The direct pressing position 118 is set at a certain point or a certain area of ​​the long section 112 .

[0109] Example 5, refer to the attached Figure 1 , Attachment Figure 8 , The specific position where the eccentric wheel 21 is pressed against the pressing rod 11 is the direct pressing position 118 .

[0110] Further, With the direct pressing position 118 as the center, the long section 112 of the pressing rod 11 is provided with single sections 117 on both sides; or: with the direct pressing position 118 as the starting point, the long section 112 of the pressing rod 11 is provided with single sections 117 towards the end of the long section 112.

[0111] Example 6, refer to the attached Figure 9 , Attachment Figure 10 , Attachment Figure 9 , with the direct pressing position 118 as the starting point, the long section 112 of the pressing rod 11 is provided with a single section 117 toward the end of the long section 112; Attachment Figure 10 With the direct pressing position 118 as the center, the long section 112 of the pressing rod 11 is provided with single sections 117 on both sides.

[0112] Further, One or more single segments 117 have an inclined angle; The single segment 117 or adjacent single segments 117 of the pressing rod 11 are close to one side of the dry filter box 8, forming an obtuse angle.

[0113] Example 7, refer to the attached Figure 9 , Attachment Figure 10 , Attachment Figure 9 , the pressing rod 11 is provided with a straight single section 117 and a single section 117 at an inclined angle, forming an obtuse angle of 177°; Attachment Figure 10 , the pressing rod 11 is provided with two single sections 117 at an inclined angle, forming an obtuse angle of 174°; The entire long section 112 of the pressing rod 11 is provided with one or more single sections 117; Or: the local long section 112 of the pressing rod 11 is provided with one or more single sections 117; The single segment 117 has an inclination angle; the single segment 117 at the end of the long segment 112 is closer to the dry filter box 8.

[0114] The end of the long segment 112 close to the short segment 113 or a nearby point or a certain point is used as the bending starting point, extending to the end of the long segment 112, and one or more single segments 117 with a small tilt angle are set as a whole or partially within the range of the long segment 112 from the bending starting point to the end of the long segment 112.

[0115] The main function of the tilt angle is that during the compression process of the eccentric wheel 21 squeezing the compression rod 11, in addition to the maximum force on the direct compression position 118, the force will be strengthened toward the far end of the long section 112, ensuring that the far end of the long section 112 can be compressed more effectively.

[0116] The inclination angle of the pressing rod 11 is designed as a whole according to the width or depth of the dry filter box 8, the distance between the direct pressing position 118 and the end of the long section 112, the pressing force of the side automatic pressing sealing structure 40, etc.

[0117] Refer to the attached Figure 7 , Attachment Figure 11 , The compression rod 11 is made of a round tube, which has sufficient strength. During the compression process, when the round tube is overlapped with the upper extension edge 81 of the dry filter box 8, it is a linear overlap, and the compression straight line 84 at the same height overlaps, and the force area is minimized. For the same force, the smaller the force area, the greater the pressure. The greater the pressure on the upper extension edge 81 of the dry filter box 8, the greater the pressure on the second elastic seal 101 of the upper air inlet dry filter module 100, and the greater the compression of the elastic space of the second elastic seal 101, the tighter the pressure will be.

[0118] Further, The eccentric wheel 21 is a cylindrical body with a certain cross-sectional area; The height of the eccentric wheel 21 is adapted to the height of the pressing rod 11; The cross-sectional area of ​​the eccentric wheel 21 is circular or arc-shaped as a whole; Or: the cross-sectional area of ​​the eccentric wheel 21 is partially circular or arc-shaped.

[0119] Example 8, refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 .

[0120] The cross-sectional area of ​​the eccentric wheel 21 is cylindrical; the eccentric wheel 21 is a solid structure with sufficient strength; the eccentric wheel 21 rotates continuously during the compacting process, and the rotation angle of the eccentric wheel 21 and the compacting rod 11 during the compacting process is 105°; the height of the eccentric wheel 21 is greater than the outer diameter of the compacting rod 11.

[0121] Further, The eccentric pressing assembly 2 includes an eccentric fixing member 23; The eccentric fixing member 23 includes an adjustable hole 231 and a limiter 22; The eccentric wheel 21 is provided with a rotation position 24 .

[0122] Example 9, refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , The rotating position 24 is used for rotating the eccentric wheel 21; the rotating position 24 is arranged in the cross section of the eccentric wheel 21 close to the clamping rod 11; the rotating position 24 is designed as an axial connection; the eccentric clamping assembly 2 includes an eccentric fixing part 23 for fixing the eccentric wheel 21; an adjustable hole 231 is provided at the connection position between the eccentric fixing part 23 and the bearing support part 4, and the adjustable hole 231 is used to adjust the front and rear positioning of the eccentric wheel 21; a limit 22 is provided on the periphery of the eccentric fixing part 23 to prevent the eccentric wheel 21 from exceeding the limit when rotating; the eccentric fixing part 23 is provided with a lower flat plate for supporting the clamping rod to ensure that the clamping rod 11 rotates at the same height in the horizontal plane, and the end of the long section 112 of the clamping rod 11 will not fall down.

[0123] Further, The pushing structure 3 is connected to the power assembly 5; The pushing structure 3 is provided with an inclined push plate 31; The inclined push plate 31 has an inclined surface 32; The inclined push plate 31 and the long section 112 of the pressing rod 11 overlap to form a certain acute angle; The area of ​​the inclined surface 32 is sufficient to cover the outer surface of the eccentric wheel in rotation and overlap, and a redundant area is provided.

[0124] Example 10, refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 .

[0125] Under the forward driving force of the power assembly 5 , the inclined push plate 31 overlaps with the eccentric wheel 21 and is gradually pressed or separated.

[0126] Further, The bearing support member 4 includes a tensioning member 41 and a bearing plate 42; The other end of the tensioning member 41 is connected to the long section 112 of the pressing rod 11 near the end; The tensioning member 41 is elastic.

[0127] Example 11, refer to the attached Figure 1 , Attachment Figure 4 , The bearing support member 4 is used to bear and fix the power assembly 5 , the pressing device 1 , the eccentric pressing assembly 2 , the pushing structure 3 , and the tensioning member 41 .

[0128] The load-bearing support member 4 is provided with a tensioning member 41 which is connected to the pressing rod 11 and automatically presses the sealing structure 40 to the open state on the side, driving the long end of the pressing rod 11 to open, fully avoiding the passage of the dry filter box 8.

[0129] The tensioning member 41 is also used to support or tension the pressing rod 11 in the height direction to maintain a horizontal state.

[0130] The tensioning member 41 is a spring and is connected to the bearing support member 4 and the pressing rod 11 .

[0131] Further, The process of the pushing structure 3 moving forward straight includes at least an unloaded section 33 and a loaded section 34; The no-load section 33 is the stage before the front of the dry filter box 8 is pushed forward and locked in place; that is, the process in which the inclined push plate 31 does not substantially press the eccentric wheel 21; The load section 34 is the stage where the dry filter box 8 is pushed forward and locked in place before being compressed from the side; that is, the inclined push plate 31 contacts the eccentric wheel 21 and the eccentric wheel 21 substantially compresses the compression rod 11 .

[0132] The load tightening stage of the side automatic tightening sealing structure 40 is designed at the end of the straight forward pushing stroke of the power component 5; it ensures that the side tightening is performed after the front locking of the dry filter box 8 is completed, and both the front and side can be locked in place in the end.

[0133] Example 12, refer to the attached Figure 1 , Attachment Figure 3 , After the front of the dry filter box 8 is locked forward, the inclined push plate 31 begins to press the eccentric wheel 21 and further presses and seals the side of the dry filter box 8 within the range of the power assembly 5 moving forward.

[0134] Before the dry filter box 8 is pushed forward and locked in place, the inclined push plate 31 is running in a no-load state without overlapping the eccentric wheel 21.

[0135] Attachment Figure 3 There is a large no-load section between the inclined push plate 31 and the eccentric wheel 21, and the stroke of the no-load section is equal to the forward push stroke of the front automatic locking sealing device 30 pressing the dry filter box 8.

[0136] The pressing rod 11 of the power assembly 5 is in an unloaded state before contacting the dry filter box 8. Before the inclined push plate 31 overlaps the eccentric wheel 21, the front of the dry filter box 8 has been locked forward. The power assembly 5 is designed to operate in at least two stages within its entire forward thrust range: one is to lock the front of the dry filter box, and the other is to compress the side. Side compression is a further tightening after the front is locked. This prevents the front of the dry filter box 8 from being unable to be pushed forward and tightened after the side is locked, resulting in inadequate front compression.

[0137] Further, The power assembly 5 adopts a linear power direction, using the horizontal forward driving force to convert it into a driving force to the left and right sides in the same horizontal plane, thereby pushing the pressing rod 11 to press the dry filter box 8.

[0138] Example 13, refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , The power assembly 5 uses a forward push cylinder, which has many advantages over the flip cylinder. During the flipping process, the cylinder will flip with the flipping action, and the connected air pipe will flip, which can easily lead to poor stability of the cylinder and air pipe, and the air pipe is prone to leaks.

[0139] The cylinder that moves forward in a straight line, the cylinder and the cylinder are not affected by the forward movement of the cylinder, and are in a fixed state. There will be no phenomenon of cylinder loosening or air pipe leakage.

[0140] Further, Each pressing surface that overlaps the pressing rod 11 is equipped with at least one combination of a pressing device 1 , an eccentric pressing assembly 2 , and a pushing structure 3 .

[0141] Example 14, refer to the attached Figure 13 , In this embodiment, a combination of a pressing device 1 and an eccentric pressing assembly 2 is used and arranged in the middle area of ​​the pressing rod 11.
