Description

Technical Field

[0001] This invention relates to the field of dry paint mist filtration in automobiles and parts, and general industrial spraying equipment, and particularly to an automatic pressing and sealing structure on the side of a dry filter box. Background Technology

[0002] In the field of dry paint mist filtration in spray painting production lines, dry paint mist filter boxes that have absorbed paint mist need to be replaced regularly. They also need to be loaded, positioned, fixed, and moved for replacement via dry filter modules. At the same time, all connections 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 to prevent paint residue from sticking to the connections and being difficult to remove, thus affecting replacement, or to prevent air leakage at the seals from affecting the balance of the circulating air in the spray booth and thus affecting the product qualification rate.

[0003] The most important and challenging aspect of dry paint mist filtration technology is solving the sealing problem at the joints, especially for dry filter boxes with top and bottom ventilation that require sealing in three axial directions while maintaining horizontal movement. The dry filter box must allow gaps for both horizontal sliding and vertical movement. It needs to be sealed at the top and bottom, locked by pushing forward from the front, and pressed inward from the sides. Furthermore, it must achieve sealing while dynamically moving and sliding under load, preventing jamming during initial advancement. The locking device must also avoid obstructing the passageway of the dry filter box. Achieving all these functions simultaneously is extremely difficult.

[0004] Existing dry paint mist collection boxes with similar technologies, such as top openings, side openings, and bottom panels, commonly employ the following original methods: two sets of front-push cylinders with flip clamps flip together to press and lock the entire dry filter box forward; one set of top-push cylinders with flip clamping plates flip together to press the upper extension edge of the dry filter box; and two sets of side cylinders with flat clamping plates push directly to press the sides of the dry filter box.

[0005] The main problems with existing similar technologies are summarized as follows:

[0006] 1. In the same dry filter box, each set is equipped with 5 sets of cylinders at different locations, all using the same air source, the same set of mechanical switches, and starting simultaneously. Due to differences in air pipe length, cylinder structure, cylinder stroke, cylinder thrust, or cylinder diameter, the radius and path of the cylinder driving the tilting clamp or tilting pressure plate are different. The flat pressure plate pushes the fastest, which affects the time difference of locking in place, resulting in asynchronous locking and causing local incomplete locking. In particular, the side cylinders will lock in place first, and the front cannot continue to push forward to the end, resulting in air leakage at the front. This is a significant problem existing in all current technologies.

[0007] 2. The side-mounted direct-push cylinder is located at the center of the length of the flat pressing plate. The cylinder has only one point of force application in the length direction, which can easily lead to uneven force on both ends of the pressing plate.

[0008] 3. Both sides of the top air inlet dry filter module are designed with longitudinal vertical sealing plates, and the cylinder longitudinal pressing plate pushes and presses the seal in the horizontal direction; the two left and right opposite vertical sealing plates need to avoid the passage for the dry filter box to move in and out; therefore, the horizontal distance between the opposite vertical sealing plates must be greater than the width of the dry filter box and leave enough 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.

[0009] 4. Limited space for side locking, making operation difficult: The distance between two adjacent dry filter modules in the length direction of a large double-sided robotic spray booth is 300-400mm. Generally, due to the modular design, processing, installation of the dry spray booth, and the size of the shipping containers for overseas transportation, it is designed as a 2-meter or 3-meter modular module design. The space for arranging the side sealing structure of the dry filter box is limited, and it is inconvenient for personnel to operate or maintain it in the narrow space on the side. Therefore, it is necessary for the equipment to occupy little space and operate stably and reliably.

[0010] 5. Each dry filter box is equipped with 5 sets of cylinders, including 2 sets on the side. The increased number of cylinders increases equipment investment. There are about 120 dry filter modules on one body line, with a total of 600 sets of cylinders in 5 sets. If the cylinders leak, the impact and wasted air source costs will be significant.

[0011] 6. To improve the strength of the side longitudinal clamping plates, the overall structure occupies a large space.

[0012] 7. Limited space for side compression, making operation difficult: The distance between two adjacent dry filter modules in the length direction of a large double-sided robotic spray booth is 300-400mm. Generally, due to the modular design, processing, installation of the dry spray booth, and the size of the shipping containers for overseas transportation, it is designed as a 2-meter or 3-meter modular module design. The limited space for arranging the side compression sealing structure makes it inconvenient for maintenance personnel to operate. Therefore, it is necessary for the equipment to occupy little space, operate stably and reliably, and be easy to operate.

[0013] As mentioned above, the structure, locking stability and reliability, locking effect, sealing effect, and investment cost of the existing dry paint mist filtration module and dry paint mist filtration box front locking and sealing device all need further optimization and improvement. Summary of the Invention

[0014] The purpose of this invention is to provide an automatic side-pressing and sealing structure for a dry filter box, addressing the difficulties and pain points existing in the prior art. A solution for an automatic side-pressing and sealing structure for a dry filter box is proposed, which, together with the top-and-bottom ventilated dry filter box, the upper air inlet dry filter module and sealing plate structure, the lower air outlet dry filter module and guide positioning wheels, the frame sealing structure and sealing strip, the front automatic locking and sealing device and power component, works in conjunction to achieve automatic side-pressing and sealing of the dry filter box, resulting in good sealing effect, high pressing strength, simple and practical structure, reliable and stable operation, low investment cost, small footprint, and convenient operation.

[0015] The above-mentioned technical objective of the present invention is achieved through the following technical solution.

[0016] An automatic side-clamping and sealing structure for a dry filter box includes: a clamping device, an eccentric clamping assembly, a pushing structure, a load-bearing support, and a power assembly;

[0017] The clamping device includes a clamping rod, a double-layer clamping member, and a clamping rod reinforcing plate; the clamping rod reinforcing plate is firmly connected to the clamping rod;

[0018] The clamping rod can rotate horizontally within the height range of the double-layer clamping member;

[0019] The eccentric clamping assembly includes an eccentric wheel, a limit switch, an eccentric fixing component, and a rotating position.

[0020] Understandable

[0021] The power component drives the pushing structure to push the eccentric wheel to rotate forward, thereby the eccentric wheel gradually applies force and directly squeezes the clamping rod, or directly squeezes the clamping rod reinforcing plate and then simultaneously squeezes the clamping rod indirectly. The clamping rod reinforcing plate is firmly connected to the clamping rod. The clamping rod can achieve overall tight contact with the side of the dry filter box. Combined with the clamping rod's ability to rotate in the horizontal direction, it achieves an opening and closing function. In the open state, it avoids the passage, and in the closed state, it clamps the side of the dry filter box. The side automatic clamping and sealing structure ultimately achieves the clamping and sealing of the upper extension edge of the dry filter box with the inclined structure of the side of the upper air inlet dry filter module and the second elastic seal.

[0022] Preferred,

[0023] The clamping rod is an integral structure;

[0024] The clamping rod includes at least a long section, a short section, and an arc-shaped connecting surface;

[0025] The long segment and the short segment are connected at an acute angle.

[0026] Understandable

[0027] The short section of the clamping rod is provided with a clamping rod rotation point, which is connected to the clamping rod double-layer fixing component;

[0028] The clamping rod can rotate horizontally around the rotation point of the clamping rod, thereby realizing the functions of opening and clamping the clamping rod;

[0029] The rotation point of the pressure rod is designed as a rotation hole or a rotation shaft;

[0030] The double-layer fixing component of the pressure rod is connected and fixed to the rotation hole or rotation shaft of the rotation point of the pressure rod;

[0031] The long section fits completely against the dry filter box, while the short section is used for rotatable connection and fixation.

[0032] During the switching between open and closed states, the long section, due to the contracted shape of the outer arc-shaped connecting surface, avoids interference with surrounding structural components throughout the dynamic rotation of the clamping rod; simultaneously, it avoids obstruction during the advancement or removal of the dry filter box.

[0033] The long section and the short section are connected at an acute angle to ensure that the first pressing point of the long section is pressed against 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 by the same distance, and the rotation angle of the pressing rod is minimized.

[0034] When the clamping rod is in the open state, the short section and the side automatic clamping and sealing structure of the opposite dry filter box do not interfere with each other, and can ensure as much as possible that the first clamping point can be clamped to the leading edge of the upper extension edge of the dry filter box.

[0035] When the clamping rod is in the clamped state, the arc-shaped connecting surface connecting the short section and the long section can be pressed and sealed with the leading edge of the upper extension of the dry filter box; thus avoiding blind spots in the clamping of the dry filter box caused by the bending space of the arc-shaped connection.

[0036] The clamping rod needs to avoid the passageway of the dry filter box; therefore, the clamping rod is in the open state during the movement of the dry filter box in and out; conversely, the clamping rod is in the closed state after the dry filter box is pushed into place.

[0037] When opened, the end of the long section of the clamping rod rotates in the opposite direction to the dry filter box, and the end of the long section of the clamping rod is furthest away from the dry filter box; conversely, when clamped, the end of the long section of the clamping rod rotates in the direction of the dry filter box, and the long section of the clamping rod is pressed parallel to the side of the dry filter box.

[0038] The pressure rod double-layer fixing component has upper and lower flat plates, openings on both sides, and a rotating structure. The lower plate supports the short section of the pressure rod to prevent it from sagging, while the upper plate limits the horizontal rotation of the pressure rod to prevent arbitrary swinging in the vertical direction. The double-flat plates also serve as the fixing component for the rotating position. The openings on both sides allow the short section of the pressure rod and the arc-shaped connecting surface to pass through and connect.

[0039] Preferred,

[0040] The dry filter box includes a side upper frame and an upper extension;

[0041] The clamping rod presses against the side upper frame or the upper extension edge of the dry filter box; the clamping rod adheres to and presses against the upper extension edge, and the upper extension edge deforms under pressure, making the seal between the upper air inlet dry filter module and the side more tight.

[0042] Understandable

[0043] The clamping rod presses against the upper extension edge, causing a certain deformation of the upper extension edge, thereby allowing the clamping rod to press deeper and tighter, and strengthening the seal with the side of the upper air inlet dry filter module.

[0044] The upper extension edge deforms under pressure, and 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 pressing of the side pressing rod, the pressing and sealing are further strengthened.

[0045] The pressing line overlaps with the second elastic seal of the upper air inlet dry filter module on the same horizontal plane and is pressed under the action of external force to compress the elasticity of the second elastic seal and achieve a seal.

[0046] Preferred,

[0047] The long section of the clamping rod is provided with a first clamping point for clamping the dry filter box;

[0048] The first clamping point is close to the short segment;

[0049] 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 tightly as a whole.

[0050] Understandable

[0051] The clamping rod and the dry filter box are pushed forward almost parallel to each other without interfering with each other. In particular, the passage is not affected at the first clamping point, and the fit is tight. The first clamping point and the upper extension edge of the dry filter box can be fitted and initially sealed by sliding naturally during the advancement without being pressed. After being advanced into place, the automatic side clamping and sealing structure will press the rod in a tighter manner.

[0052] The position of the first clamping point can completely clamp the front end of the dry filter box, avoiding blind spots in clamping.

[0053] Preferred,

[0054] The clamping rod has a direct clamping position in the long section;

[0055] The direct pressing position is set at a certain point or in a certain area of ​​the long segment.

[0056] Understandable

[0057] The direct clamping position is designed as the specific location where the eccentric wheel clamps the clamping rod.

[0058] The direct clamping position can also be designed as the area where the eccentric wheel clamps the reinforcing plate of the pressure bar.

[0059] Preferred,

[0060] 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 at the end of the long section.

[0061] Understandable

[0062] The main function of the single segment with the inclined angle of the long section is to increase the pressure towards the far end of the long section during the pressing process of the pressing rod, in addition to the maximum force on the direct pressing position, so as to ensure that the far end of the long section can be pressed more effectively.

[0063] Preferred,

[0064] One or more of the aforementioned segments have an inclination angle;

[0065] The single segment of the clamping rod, or the side adjacent to the single segment near the dry filter box, forms an obtuse angle.

[0066] Understandable

[0067] Centered on the direct pressing position, the long section of the pressing rod is provided with single sections on both sides, and each section has an obtuse angle. During the pressing process of the eccentric wheel, the certain elasticity of the pressing rod is used to flatten the obtuse angle into a straight line, and the far 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, which would cause uneven force on the pressing rod.

[0068] The single segment of the long end of the clamping rod and the main body of the long segment form an obtuse angle on the side near the dry filter box; that is, the end of the long segment overlaps with the dry filter box in advance, and after the direct clamping position is pressed, the end of the long segment exerts greater force on the dry filter box and presses it tighter.

[0069] By pressing the first pressing point, and utilizing the lever principle of the pressing rod, a second pressing position, namely the direct pressing position, is set within the long section of the pressing rod. While pressing the direct pressing position, the first pressing point will be pressed even tighter. Combined with the tilt angle of a single section of the pressing rod within the long section, the long section is driven to come closer to the side of the dry filter box under the dual action, thereby ensuring a better overall pressing effect of the pressing rod.

[0070] The tilt angle of the single section is designed as a whole based on the width or depth of the dry filter box, the distance of the direct pressing position, the distance of the ends of the long section, and the pressing force of the side automatic pressing and sealing structure.

[0071] Preferred,

[0072] The eccentric wheel is a cylindrical body with a cross-sectional area;

[0073] The height of the eccentric wheel is adapted to the height of the clamping rod;

[0074] The cross-sectional area of ​​the eccentric wheel is generally circular or arc-shaped;

[0075] Alternatively: The cross-sectional area of ​​the eccentric wheel is locally circular or arc-shaped.

[0076] Understandable

[0077] The eccentric wheel is a cylindrical solid structure with sufficient strength; the eccentric wheel rotates continuously during the clamping process, and the overlap area or stroke distance with the clamping rod or the reinforcing plate of the clamping rod is designed with a certain redundancy. The installation position of the eccentric wheel in the front-to-back direction can be adjusted; the cross-sectional area of ​​the eccentric wheel is designed to be circular or arc-shaped, making continuous force application more stable and reliable; the height of the eccentric wheel covers the height of the clamping rod, resulting in a large force application area and more uniform force application.

[0078] Preferred,

[0079] The eccentric clamping assembly includes an eccentric fixing element;

[0080] The eccentric fastener includes an adjustable hole and a limiting device;

[0081] The eccentric wheel has a rotating position.

[0082] Understandable

[0083] The rotating position is used for the eccentric wheel to rotate;

[0084] The rotating part is designed as an axial connection;

[0085] The eccentric clamping assembly is provided with an eccentric fixing component;

[0086] The rotating position is arranged within the cross-section of the eccentric wheel, close to the clamping rod;

[0087] 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;

[0088] The eccentric fixing component is provided with a limit switch to prevent the eccentric wheel from rotating beyond the limit;

[0089] The eccentric fixing member is provided with a lower flat plate to support the clamping rod, ensuring that the clamping rod rotates within the same height on the horizontal plane and that the long end of the clamping rod does not droop.

[0090] Preferred,

[0091] The pushing structure is connected to the power assembly;

[0092] The pushing structure is equipped with a sloping push plate;

[0093] The inclined push plate has an inclined surface;

[0094] The inclined surface overlaps with the long section of the clamping rod to form an acute angle;

[0095] The surface area of ​​the inclined plane is sufficient to cover the outer surface that rotates and overlaps with the eccentric wheel, and a redundancy is provided.

[0096] Understandable

[0097] Under the forward thrust of the power assembly, the inclined push plate engages with the eccentric wheel and presses against the clamping rod; conversely, when the inclined push plate retracts, the eccentric wheel separates from the clamping rod.

[0098] Preferred,

[0099] The load-bearing support includes a tensioning element and a load-bearing plate;

[0100] The other end of the tensioning member is connected to the long section of the clamping rod near its end;

[0101] The tensioning element is elastic.

[0102] Understandable

[0103] The bearing support is used to support and fix the power component, the clamping device, the eccentric clamping component, the pushing structure, the tensioning component, etc.

[0104] One end of the tensioning member is fixed to the bearing support member, and the other end is connected to the clamping rod;

[0105] The function of the tensioning member is to open the long section of the pressure rod by rotating it outward through its elastic tension, so that the pressure rod completely avoids the passageway of the dry filter box when it is in the open state.

[0106] Preferred,

[0107] A method for using an automatic side-clamping sealing structure for a dry filter box.

[0108] The process of the pushing structure moving straight forward includes at least an unloaded section and a loaded section.

[0109] The unloaded section is the stage before the front 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.

[0110] The load section is the stage where the front of the dry filter box is pushed forward and locked into place, and then the side is pressed; 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.

[0111] The load-pressing stage of the automatic side-mounted sealing structure is designed at the very end of the forward stroke of the power component.

[0112] Understandable

[0113] After the front of the dry filter box is locked in place, the inclined push plate begins to press the eccentric wheel, and further presses and seals the side of the dry filter box within the stroke range of the forward movement of the power assembly.

[0114] Before the automatic dry filter box is fully locked in front, the inclined push plate is running in an unloaded state and does not engage with the eccentric wheel.

[0115] The power unit is designed with at least two operations throughout the entire forward stroke: first, front locking of the dry filter box, and second, side pressing; side pressing is a further pressing after the front locking is completed.

[0116] The automatic side-clamping sealing structure is designed at the very end of the straight-forward stroke of the power component; this ensures that the side clamping is performed only after the front of the dry filter box is locked, and that both the front and side are ultimately locked in place.

[0117] Preferred,

[0118] The power assembly adopts a linear power direction; the horizontal forward thrust is converted into a thrust to the left and right sides on the same horizontal plane, thereby pushing the clamping rod to press the dry filter box.

[0119] Understandable

[0120] The power unit can be powered by cylinders, motors, or other similar devices.

[0121] It adopts a direct-thrust cylinder, which uses forward thrust as a power source, resulting in better stability;

[0122] The power unit can be set separately, or the power source of the front automatic locking and sealing device can be utilized.

[0123] It adopts a linear cylinder with direct front and rear thrust, so there is no loss of forward thrust; and there is no need for the cylinder to flip or the air pipe to flip with the locking action. The cylinder body is fixed and the air pipe connected to the cylinder is also fixed, so there is no risk of air leakage due to the dynamic effect of flipping.

[0124] Once the forward-pushing cylinder is fixed, the main body is in a fixed state except for the cylinder push shaft. It is not affected by the forward movement of the cylinder, so it has good stability. There are almost no errors or deviations in the forward pushing process of the cylinder, and there will be no problems such as cylinder loosening or air leakage in the air pipe.

[0125] Preferred,

[0126] Each clamping surface that overlaps with the clamping rod is configured with at least one combination of clamping device and eccentric clamping assembly.

[0127] In summary, the main key points and beneficial effects of the technical solution of the present invention are summarized as follows.

[0128] 1. The pushing structure moves forward in a straight line, with two functional sections: an unloaded section and a loaded section. The unloaded section is locked from the front first, and the loaded section is further pressed from the side to ensure that the front and sides of the dry filter box are locked in place and to improve the sealing effect.

[0129] 2. By controlling the spacing of the eccentric pressing component and the inclined push plate of the pressing structure, the delayed side pressing is controlled, ensuring that the front locking is fully in place and improving the locking and sealing effect.

[0130] 3. A horizontally rotatable clamping rod is adopted. Utilizing the lever principle of the clamping rod, force is applied to the clamping rod at multiple points through the first clamping point, the direct clamping position, the optional connection of the clamping rod reinforcing plate, and the tilt angle of a single section of the long clamping rod. This results in a better overall clamping and sealing effect throughout the entire length of the clamping rod.

[0131] 4. The clamping rod is a tubular component that overlaps with the upper extension of the dry filter box to form a clamping straight line, which is subjected to the greatest pressure. The clamping rod directly clamps the upper extension and then indirectly clamps the second elastic seal. The second elastic seal undergoes compression deformation, which effectively strengthens the seal.

[0132] 5. The horizontal clamping line of the clamping rod can be selected within the height range between the connecting line of the frame and the upper extension of the dry filter box; this design can both clamp the main frame of the dry filter box for positioning and clamp the upper extension of the dry filter box for sealing.

[0133] 6. The eccentric wheel directly compresses the clamping rod or indirectly compresses it through the reinforcing plate of the clamping rod, resulting in uniform and strong overall compression force and stable operation; the position, distance, and angle of compression are adjustable, enabling precise compression; it has a large dimensional tolerance for dry filter module equipment, avoiding installation errors from affecting the compression effect.

[0134] 7. In the open position, the long end of the clamping rod rotates horizontally outward through the elastic tensioning element to clear the passage, facilitating the smooth passage of the dry filter box during replacement.

[0135] 8. The double-layer plate design of the double-layer fixing component of the pressure bar has a limiting function. The pressure bar will not swing up and down in the same horizontal direction and always maintains a horizontal state. The connection between the components has good stability and ensures that the pressure bar is straight and horizontal.

[0136] 9. The limit switch of the eccentric wheel prevents the eccentric wheel from jamming due to its extreme position.

[0137] 10. The front thrust assembly of the shared front automatic locking sealing device is used to eliminate the power assembly, thereby reducing investment costs and maintenance costs.

[0138] In contrast to the problems of existing technologies, the technical features and beneficial effects of the present invention are explained one by one as follows.

[0139] 1. It uses the same power unit for the front automatic locking and sealing device, making the equipment simple, practical, and stable in performance.

[0140] 2. The adjacent sides of two dry filter boxes along the length of the spray booth adopt the same automatic side-pressing sealing structure. The symmetrical arrangement ensures structural stability and even force is applied to both sides, reducing investment costs. One control system simplifies operation.

[0141] 3. Existing technology uses a longitudinal pressing plate to apply pressure to the longitudinal vertical sealing plate; this invention uses a pressing rod for straight pressing, which has the smallest pressing area and greater pressing strength; combined with the inclined structure of the side sealing plate of the upper air inlet dry filter module and the arrangement of the second elastic seal, the upper extension of the dry filter box slides with zero gap overlap with the second elastic seal in an elastic compression state; under the premise of achieving the first side seal, the second strengthening pressing seal is applied, resulting in a better sealing effect.

[0142] 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 and slids forward. Even when it reaches the first clamping point, it can pass through with almost no resistance when the clamping rod is rotated open. The clamping rod is locked and the clamping is tighter.

[0143] 5. Make full use of the width direction of the frame sealing structure to arrange the short section of the clamping rod, ensuring 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, avoiding the clamping blind zone at the leading edge of the upper extension edge of the dry filter box on the arc-shaped connection surface of the clamping rod, and achieving full clamping and sealing of the upper extension edge.

[0144] 6. The overall side automatic compression sealing structure, modular design and installation result in higher efficiency, precise installation, convenient operation, and small space occupation; redundancy is reserved for connections within the range of possible errors caused by surrounding connected equipment, allowing for precise adjustments.

[0145] 7. The side-pressing sealing structure of the dry filter box requires the combination of 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 requires cooperation from all parties and none of them can be omitted.

[0146] In summary, the side-mounted automatic sealing structure has significant advantages in terms of sealing effect, locking stability and reliability, overall sealing, equipment investment cost, small footprint, degree of automation, ease of operation, cooperation with peripheral equipment, maintenance, smooth operation, operational stability, and reliability.

[0202] See attached document Figures 1 to 13 The diagram shown is a structural schematic of an automatic side-clamping and sealing structure for a dry filter box provided by the present invention.

[0203] The side automatic pressing and sealing structure 40 includes: a pressing device 1, an eccentric pressing component 2, a pushing structure 3, a load-bearing support component 4, and a power component 5;

[0204] The clamping device 1 includes a clamping rod 11, a double-layer clamping rod fixing member 12, and a clamping rod reinforcing plate 13; the clamping rod reinforcing plate 13 is firmly connected to the clamping rod 11; the clamping rod 11 can rotate horizontally within the height range of the double-layer clamping rod fixing member 12.

[0205] The eccentric clamping assembly 2 includes an eccentric wheel 21, a limit 22, an eccentric fixing part 23, and a rotating part 24.

[0206] Example 1, refer to Appendix Figure 1 ,

[0207] The pressure bar reinforcing plate 13 is designed as a U-shaped groove structure and is welded and fixed to the pressure bar 11; the U-shaped groove structure has a longitudinal surface for the side of the eccentric wheel 21 to overlap and press against the longitudinal surface.

[0208] The double-layer fixing member 12 of the pressure rod has two flat plates, the bottom flat plate is used to support the pressure rod 11, and the upper flat plate is used to limit the rotation of the pressure rod 11 in the horizontal plane; the limit 22 of the eccentric pressure 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.

[0209] The eccentric fastener 23 is designed with front and rear slots, and is connected and fixed to the bearing support 4 through bolt assembly. The installation position of the eccentric fastener 23 can be adjusted front and rear, thereby precisely controlling the front and rear position of the eccentric wheel 21 pressing the clamping rod 11 or the pressure rod reinforcing 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 pressing position, and the displacement distance of pressing to the side, thus determining the pressing strength of the clamping rod 11.

[0210] The rotating position 24 is connected to the double-layer fixing part 12 of the pressure rod by a pin, so as to realize the rotation of the pressure rod 11 in the horizontal direction; the end of the long section 112 of the pressure rod 11 is opened when rotated outward and pressed when rotated inward; in the open state, it avoids the passage of the dry filter box 8, and in the pressed state, it realizes the second elastic seal 101 arranged on the inclined structure 111 on the side of the upper air inlet dry filter module 100 is pressed and sealed with the upper extension 81 of the dry filter box 8.

[0211] The side automatic pressing and sealing structure 40, the power component 5 drives the eccentric wheel 21 of the eccentric pressing component 2 to press the pressing rod 11 of the pressing device 1 through the pushing structure 3. The pressing rod 11 is close to the dry filter box, and the force is applied to the pressing rod 11 in the process of the eccentric wheel 21 gradually rotating under force, so as to achieve the side pressing and sealing effect of the dry filter module 100 at the air inlet of the dry filter box 8.

[0212] Furthermore,

[0213] The clamping rod 11 is a one-piece structure; it is made from a single bent tube.

[0214] The clamping rod 11 includes a long section 112, a short section 113, and an arc-shaped connecting surface 114; the arc-shaped connecting surface is externally contracted.

[0215] The long segment 112 and the short segment 113 are connected to form an acute angle.

[0216] Example 2, see attached document Figure 1 Appendix Figure 8 ,

[0217] 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 member 12. The clamping rod 11 can rotate in the horizontal direction with the clamping rod rotation point 115 as the axis, so as to realize the function of opening and clamping the clamping rod 11. The clamping rod rotation point 115 is designed with a rotation hole, and the clamping rod double-layer fixing member 12 and the rotation hole of the clamping rod rotation point 115 are connected by a pin.

[0218] During the switching between open and closed states of the long section 112, the arc-shaped connecting surface 114 does not interfere with the surrounding structural components during dynamic rotation.

[0219] The clamping rod 11 must avoid the passageway of the dry filter box 8; during the movement of 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 clamped state.

[0220] When opened, the end of the long section 112 of the clamping rod 11 is pulled parallel to the dry filter box 8 in the opposite direction with the rotation point 115 of the clamping rod as the axis, and the end of the long section 112 of the clamping rod 11 is furthest from the dry filter box 8.

[0221] Conversely, during tightening, the end of the long section 112 of the tightening rod 11 is pulled parallel to and pressed against the dry filter box 8 with the rotation point 115 of the tightening rod as the axis, and the long section 112 of the tightening rod 11 is pressed parallel to the dry filter box 8.

[0222] The pressure rod rotation point 115 has a through-hole in the straight section of the short segment 113, which is connected by a shaft, pin, etc.; the pressure rod double-layer fixing part 12 has a double-layer flat plate, double-sided openings, and a rotating structure; the lower plate of the double-layer flat plate is used to support the pressure rod 11, and the upper plate is used to limit the height of the pressure rod 11 when it rotates in the horizontal direction, so as to prevent the pressure rod from swinging arbitrarily in the height direction; the double-layer flat plate is also used to fix the pressure rod 11 firmly; the double-sided openings are used for the short segment 113 of the pressure rod 11 and the arc-shaped connecting surface 114 to pass through and connect.

[0223] Furthermore,

[0224] The dry filter box 8 includes a side upper frame 83 and an upper extension 81;

[0225] The clamping rod 11 clamps the upper extension 81 of the side of the dry filter box 8 to form the clamping straight line 84;

[0226] The compression straight line 84 is designed to be at the overlap of the side upper frame 83 and the upper extension 81 or closer to the upper extension 81;

[0227] The clamping 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 clamping rod 11 can press deeper and tighter.

[0228] Example 3, refer to Appendix Figure 1 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 11 ,

[0229] Simultaneously, 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 81. The upper extension 81 of the dry filter box 8 is already in a sealed state during the sliding process. After it is in place, it is further tightened by the pressing of the side pressing rod 11.

[0230] Furthermore,

[0231] The long section 112 of the clamping rod 11 is provided with a first clamping point 116 for clamping the dry filter box 8;

[0232] The first clamping point 116 is located near the short segment;

[0233] 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 tightly as a whole.

[0234] Example 4, see attached document Figure 1 Appendix Figure 8 ,

[0235] Before the dry filter box 8 is pushed forward, the clamping rod 11 is in the open state. The clamping rod 11 and the upper extension edge 81 of the dry filter box 8 have a very small separation angle and distance. The separation angle is within 2-3°, which can ensure that the distance between the end of the long section 112 of the clamping rod 11 and the front edge 82 of the upper extension edge 81 of the dry filter box 8 is more than 30mm. Under the guidance of the guide wheel of the dry filter module 200 at the lower air outlet, the error of the dry filter box 8 shifting to the left or right on one side after being pushed forward and in place does not exceed 3mm. Therefore, even a 1° rotation angle can make the clamping rod 11 completely avoid the passage, ensuring the smooth passage of the dry filter box 8.

[0236] The upper extension edge 81 of the dry filter box 8 is 1-2° away from the clamping rod 11, and is almost parallel and aligned. As long as the dry filter box 8 moves forward and enters the area of ​​the clamping rod 11, it will not be blocked by the clamping rod 11. Even when the two reach the first clamping point 116, the resistance is 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.

[0237] Even with some resistance, the second elastic seal 101 of the upper air inlet dry filter module 100 is pressed tightly, and the dry filter box 8 slides by overlapping with the second elastic seal 101 along the upper extension edge 81. Taking advantage of the smoothness of the outer casing material of the dry filter box 8, the sliding is smooth when overlapping with the second elastic seal 101. In this way, both effective sealing and smooth sliding can be achieved.

[0238] Therefore, 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 their natural state. Then, under the external force of the side automatic pressing sealing structure 40, it will be pressed tighter and tighter.

[0239] In the natural state when the dry filter box 8 is not pressed open, the distance between the first pressing point 116 and the side outer casing of the dry filter box 8 is such that after the dry filter box 8 has been pushed into the upper air inlet dry filter module 100 and is in place, the leading edge 82 of the upper extension 81 of the dry filter box 8 is in place, and the arc-shaped connecting surface 114 of the pressing rod 11 or the first pressing point 116 has been pressed against the upper extension 81 of the dry filter box 8; after the pressing rod 11 is under force, the first pressing point of the pressing rod 11 is pressed more firmly and tightly; when in the open state, the dry filter box 8 can be moved out smoothly; before the dry filter box 8 is pushed in again, the pressing rod 11 is opened in advance to ensure that the dry filter box 8 is pushed in smoothly.

[0240] The first pressing point 116 of the rotatable pressing rod 11 and the adjustable eccentric wheel 21 apply force indirectly or directly to the length area extending to both sides of the direct pressing position 118 of the pressing rod 11. Combined with the single segment 117 of the inclined angle at the end of the long section 112 of the pressing rod 11, the three forces work together to apply force to different areas of the pressing rod 11 and the appropriate pressure. Under the original driving force of the power component 5, the inclined push plate 31 of the pushing structure 3 is driven to press the eccentric wheel 21, thus achieving the side pressing and sealing of the dry filter box 8.

[0241] Furthermore,

[0242] The clamping rod 11 has a direct clamping position 118 in its long section 112;

[0243] The direct pressing position 118 is set at a certain point or a certain area of ​​the long segment 112.

[0244] Example 5, see attached document Figure 1 Appendix Figure 8 ,

[0245] The eccentric wheel 21 is pressed against the clamping rod 11 at the direct clamping position 118.

[0246] Furthermore,

[0247] 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 at the end of the long section 112.

[0248] Example 6, see attached document Figure 9 Appendix Figure 10 ,

[0249] Appendix Figure 9 Starting from the direct pressing position 118, a single section 117 is provided at the end of the long section 112 of the pressing rod 11.

[0250] Appendix 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.

[0251] Furthermore,

[0252] One or more individual segments 117 have an inclination angle;

[0253] The single segment 117 of the clamping rod 11 or the side of the adjacent single segment 117 near the dry filter box 8 forms an obtuse angle.

[0254] Example 7, see attached document Figure 9 Appendix Figure 10 ,

[0255] Appendix Figure 9 The clamping rod 11 has a straight single segment 117 and an inclined single segment 117, forming an obtuse angle of 177°;

[0256] Appendix Figure 10 The clamping rod 11 has two single segments 117 with two tilt angles, forming an obtuse angle of 174°;

[0257] The entire length 112 of the clamping rod 11 is provided with one or more individual segments 117;

[0258] Alternatively: a local long section 112 of the clamping rod 11 may be provided with one or more single sections 117;

[0259] The single section 117 has an inclined angle; the single section 117 at the end of the long section 112 is closer to the dry filter box 8.

[0260] Taking the end or a point near the short segment 113 of the long segment 112 as the starting point of the bend, and extending to the end of the long segment 112, one or more single segments 117 with a small tilt angle are set in the whole or in part within the range of the long segment 112 from the starting point of the bend to the end of the long segment 112.

[0261] The main function of the tilt angle is that, during the pressing process of the eccentric wheel 21 pressing the clamping rod 11, in addition to the direct pressing position 118 being subjected to the greatest force, the force will be strengthened towards the far end of the long section 112, ensuring that the far end of the long section 112 can be pressed more effectively.

[0262] The tilt angle of the clamping rod 11 is designed based on the width or depth of the dry filter box 8, the distance between the direct clamping position 118 and the end of the long section 112, and the clamping force of the side automatic clamping sealing structure 40.

[0263] See attached document Figure 7 Appendix Figure 11 ,

[0264] The clamping rod 11 is made of a round tube, which has sufficient strength. During the clamping process, when the round tube overlaps with the upper extension 81 of the dry filter box 8, it is a linear overlap. The clamping straight line 84 overlaps within the same height, resulting in the smallest force-bearing area. For the same force, the smaller the force-bearing area, the greater the pressure. The greater the pressure on the upper extension 81 of the dry filter box 8, the greater the pressure indirectly 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, resulting in a tighter clamping.

[0265] Furthermore,

[0266] The eccentric wheel 21 is a cylindrical body with a certain cross-sectional area;

[0267] The height of the eccentric wheel 21 is adapted to the height of the clamping rod 11;

[0268] The cross-sectional area of ​​the eccentric wheel 21 is generally circular or arc-shaped;

[0269] Alternatively: The cross-sectional area of ​​the eccentric wheel 21 is locally circular or arc-shaped.

[0270] Example 8, see attached document Figure 1 Appendix Figure 2 Appendix Figure 3 .

[0271] The eccentric wheel 21 has a cylindrical cross-sectional area; the eccentric wheel 21 is a solid structure with sufficient strength; the eccentric wheel 21 rotates continuously during the pressing process, and the rotation angle between the eccentric wheel 21 and the pressing rod 11 during the pressing process is 105°; the height of the eccentric wheel 21 is greater than the outer diameter of the pressing rod 11.

[0272] Furthermore,

[0273] The eccentric clamping assembly 2 includes an eccentric fastener 23;

[0274] The eccentric fastener 23 includes an adjustable hole 231 and a limit 22;

[0275] The eccentric wheel 21 is provided with a rotating position 24.

[0276] Example 9, see attached document Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 ,

[0277] Rotation position 24 is used for the rotation of eccentric wheel 21; rotation position 24 is arranged in the cross section of eccentric wheel 21 close to clamping rod 11; rotation position 24 is designed as axial connection; eccentric clamping assembly 2 includes eccentric fixing member 23 for fixing eccentric wheel 21; the connection position between eccentric fixing member 23 and bearing support member 4 is provided with adjustable hole 231, adjustable hole 231 is used to adjust the front and rear positioning of eccentric wheel 21; limit 22 is provided on the periphery of eccentric fixing member 23 to prevent eccentric wheel 21 from exceeding the limit when rotating; eccentric fixing member 23 is provided with lower plane plate for supporting clamping rod, ensuring that clamping rod 11 rotates within the same height in the horizontal plane, and the end of the long section 112 of clamping rod 11 will not droop.

[0278] Furthermore,

[0279] The push-press structure 3 is connected to the power assembly 5;

[0280] The pushing structure 3 is provided with an inclined push plate 31;

[0281] The inclined push plate 31 has an inclined surface 32;

[0282] The inclined push plate 31 and the long section 112 of the clamping rod 11 overlap to form a certain acute angle;

[0283] The area of ​​the inclined plane 32 is sufficient to cover the outer surface that overlaps with the rotating eccentric wheel, and a redundant area is provided.

[0284] Example 10, see attached document Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 .

[0285] Under the forward thrust of the power assembly 5, the inclined push plate 31 gradually presses against or separates from the eccentric wheel 21 after it engages with it.

[0286] Furthermore,

[0287] The load-bearing support 4 includes a tensioning member 41 and a load-bearing plate 42;

[0288] The other end of the tensioning member 41 is connected to the long section 112 near the end of the clamping rod 11;

[0289] The tensioning element 41 is elastic.

[0290] Example 11, see attached document Figure 1 Appendix Figure 4 ,

[0291] The support member 4 is used to support the fixed power component 5, the clamping device 1, the eccentric clamping component 2, the pushing structure 3, and the tensioning member 41.

[0292] The bearing support 4 is equipped with a tensioning member 41, which is connected to the clamping rod 11. When the side automatically clamps the sealing structure 40 in the open state, it drives the long end of the clamping rod 11 to open, fully avoiding the passage of the dry filter box 8.

[0293] The tensioning element 41 is also used to bear or tighten the clamping rod 11 in the height direction to keep it in a horizontal state.

[0294] The tensioning element 41 is a spring connected to the load-bearing support 4 and the clamping rod 11.

[0295] Furthermore,

[0296] The process of pushing the pressing structure 3 forward in a straight line includes at least an unloaded section 33 and a loaded section 34.

[0297] The unloaded section 33 is the stage before the front of the dry filter box 8 is pushed forward and locked into place; that is, the process in which the inclined push plate 31 does not substantially press the eccentric wheel 21.

[0298] The load section 34 is the stage where the front of the dry filter box 8 is pushed forward and locked into place, and then the side is pressed; that is, the process in which the inclined push plate 31 contacts the eccentric wheel 21, and the eccentric wheel 21 substantially presses the pressing rod 11.

[0299] The load-pressing stage of the automatic side-clamping sealing structure 40 is designed at the very end of the straight-forward stroke of the power component 5; this ensures that the side clamping is performed only after the front of the dry filter box 8 is locked, and that both the front and side are eventually locked in place.

[0300] Example 12, see attached document Figure 1 Appendix Figure 3 ,

[0301] After the front of the dry filter box 8 is locked in place, 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 stroke range of the forward movement of the power assembly 5.

[0302] Before the dry filter box 8 is fully locked in front, the inclined push plate 31 is in an unloaded state and does not engage with the eccentric wheel 21.

[0303] Appendix Figure 3 There is a large unloaded section between the inclined push plate 31 and the eccentric wheel 21. The stroke of the unloaded section is equal to the forward push stroke of the front automatic locking sealing device 30 pressing the dry filter box 8.

[0304] The clamping rod 11 of the power assembly 5 is unloaded before contacting the dry filter box 8. Before the inclined push plate 31 and the eccentric wheel 21 are engaged, the dry filter box 8 is locked with its front facing forward.

[0305] The power unit 5 is designed with at least two operations throughout its entire forward stroke: first, locking the front of the dry filter box, and second, pressing the sides. The side pressing is a further pressing after the front is locked, to avoid the front being unable to be pushed forward and pressed after the sides of the dry filter box 8 are locked, which would result in incomplete front pressing.

[0306] Furthermore,

[0307] The power assembly 5 adopts a linear power direction, which uses the horizontal forward thrust to convert into thrust on the left and right sides in the same horizontal plane, thereby pushing the clamping rod 11 to clamp the dry filter box 8.

[0308] Example 13, see attached document Figure 1 Appendix Figure 2 Appendix Figure 3 ,

[0309] The power unit 5 uses a forward-pushing cylinder, which has many advantages over a tilting cylinder. During the tilting process, the cylinder and the connected air pipe tilt together, which can easily lead to poor stability of the cylinder and air pipe, and the air pipe is prone to leakage.

[0310] The cylinder moves forward in a straight line. The cylinder and the cylinder itself are not affected by the forward movement of the cylinder. They are in a fixed state and there will be no loosening of the cylinder or leakage of the air pipe.

[0311] Furthermore,

[0312] Each clamping surface that overlaps with the clamping rod 11 is equipped with at least one combination of clamping device 1, eccentric clamping assembly 2, and pushing structure 3.

[0313] Example 14, see attached document Figure 13 ,

[0314] In this embodiment, a combination of a clamping device 1 and an eccentric clamping assembly 2 is used, which is arranged in the middle area of ​​the clamping rod 11.
