Description

TECHNICAL FIELD

[0001] The present application relates to the field of dry paint mist filtering of automobile and parts, general industrial spraying equipment, and particularly relates to a dry filtering module with up-down ventilation and a lower air outlet and a sealing structure. BACKGROUND

[0002] A robot spraying room generates a large amount of oversprayed paint mist, which needs to be filtered and absorbed by a dry paint mist filtering box. The dry paint mist filtering box is arranged in the ventilation channel of the paint mist airflow of the spraying room and needs to withstand the force of 3000 Pa high-pressure airflow. After the dry paint mist filtering box absorbs paint, the self-weight of the dry paint mist filtering box increases. The disposable consumables of the dry paint mist filtering box need to be replaced regularly and moved horizontally. Therefore, the dry paint mist filtering box needs to be loaded, fixed, carried and moved by the dry filtering module of the fixed structure. The dry paint mist filtering box is independent or connected to a secondary carrier and is movably connected to the dry filtering module. There is a gap when there is a movable connection, and the gap needs to be sealed and locked and compressed.

[0003] The paint mist airflow of a robot automatic spraying room is from top to bottom. From the perspective of airflow, dry paint mist filtering effect and filtering efficiency, airflow resistance and other aspects, the dry filtering box is most reasonable in terms of up-down ventilation direction.

[0004] The most important and most difficult point of dry paint mist filtering technology is to solve the sealing problem of the connection. In particular, the dry filtering box with up-down ventilation needs to be sealed in three axial directions and can move horizontally. The dry filtering box needs to be sealed in up-down directions, front pushed and locked in the front, and compressed inward in the side, and needs to be sealed while moving and sliding dynamically under the premise of carrying.

[0005] If the gap between the dry filtering module and the dry filtering box is large, the dry filtering box can pass through without any difficulty, but the larger the gap, the more difficult it is to seal.

[0006] The prior art uses a sliding structure hung on the upper part to carry the dry filtering box. The upper air inlet is in the windward surface of the paint mist, and the paint mist is the largest. The air is sent under pressure. Once the air leaks, the paint mist will overflow the workshop, and it will be difficult to separate and replace after the paint slag sticks to the leakage. The bottom of the dry filtering box needs to be carried and sealed. Once the air leaks, it is easy to cause dirty air in the workshop to enter the clean circulating air system of the spraying room, causing pollution and damaging the air balance stability, thereby affecting the product qualification rate.

[0007] In the prior art, the dry filtering box with upwind or upwind air inlet is arranged on the upper part, and the side surface is arranged with an air inlet or an air outlet. The airflow is turned by 90 degrees in the dry filtering box, rather than in the up-down ventilation mode. The dry filtering box has a bottom plate. The bottom plate is easy to move, and the bottom does not need to be sealed.

[0008] In the prior art, the dry filter box with up and down ventilation needs to be carried by a secondary carrier, such as a mobile carrying trolley added outside the dry filter box, or a metal frame, or a metal box and a plastic film, or a rolling structure added at the bottom; the secondary carrier structure is complex and high in cost, and further increases the secondary sealing connection, which is more difficult to seal.

[0009] The independent overall dry filter box with up and down ventilation without a secondary carrier is carried at the bottom, and the body of the overall dry filter box can realize carrying, sliding and sealing, which is a blank in the prior art.

[0010] The independent overall dry filter box carried at the bottom has many technical difficulties.

[0011] 1. The dry filter box is carried at the bottom, the sealing of the lower part of the dry filter box is also at the bottom, and the dry filter box also needs to be connected to the bottom for sliding. The two need to be in contact for carrying and sealing, and the sliding operation of the dry filter box moving in and out cannot be affected by the sealing for smoothness.

[0012] 2. If the sliding structure at the bottom is used, a gap will be generated, and air will leak at the gap.

[0013] 3. The dry filter box increases in weight by about 200-300 Kg after absorbing paint, and the sliding resistance is also large.

[0014] 4. The overall dry filter box with up and down ventilation has a large size, uses a wooden frame skeleton and a paper outer box, and the paperboard is easy to deform. The wooden frame is also easy to deform if it is locally pressed, and a large deformation will affect the sealing effect.

[0015] 5. The upper air inlet dry filter module and the lower air outlet dry filter module are respectively connected with the upper air inlet and the lower air outlet of the dry filter box for sliding. The center lines of the front, back, left, right, up and down can be completely aligned without deviation, otherwise the precision of each connection point of the dry filter box will be affected, and the sealing effect will be affected.

[0016] Therefore, it is necessary to develop and design an independent overall dry filter box with up and down ventilation, which can solve the problems of carrying, moving and sliding, and sealing, and achieve good sealing effect with low investment cost and convenient replacement. SUMMARY

[0017] The application aims to provide a lower air outlet dry filter module and sealing structure for up and down ventilation to solve the difficulties and pain points in the prior art. The application provides a solution of a lower air outlet dry filter module and sealing structure for up and down ventilation, which is matched with a dry filter box for up and down ventilation, a dry filter module for upper air inlet, a frame sealing structure, an automatic locking sealing device, a side automatic locking structure, etc., to realize bearing sliding and sealing, good sealing, no paint mist, convenient replacement, investment cost saving, etc.

[0032] The roller bears and drives the dry filtering box to slide;

[0033] The bearing framework bears the body of the side sealing plate and the front sealing plate and all structures borne thereon.

[0034] The bearing framework is designed with an inwardly small and outwardly expanded guide rail at the inlet and outlet ends of the dry filtering box.

[0035] It should be noted that,

[0036] The side sealing plate, the sliding device and all structures borne by the side sealing plate are designed as a modular module, which has good overall strength, small error, uniform stress and convenient processing and manufacturing, and simplifies the installation on site.

[0037] The connection between the roller groove and the roller has a gap to facilitate rotation of the roller, and the gap will cause air leakage, and therefore, the sealing problem needs to be solved.

[0038] The bearing framework is designed with an inwardly small and outwardly expanded guide rail at the inlet and outlet ends of the dry filtering box, and the main purpose is to facilitate the butt joint of the dry filtering box and the dry filtering module; when the dry filtering box is initially pushed, under the action of the guide rail, accurate positioning is achieved, the front sealing rail can be overlapped smoothly, and under the secondary guiding action of the guide wheel, accurate movement in the channel is achieved, and the dry filtering box is prevented from being stuck.

[0039] The sliding device, the roller groove and the roller are respectively detachable structures, which are convenient for maintenance of the roller.

[0040] The bearing framework is used for bearing the whole dry filtering module and the dry filtering box with increased weight after absorbing paint; the bearing framework bears the side sealing plate and the front sealing plate, the side sealing plate bears the roller groove, the roller groove bears the roller, and the roller bears the dry filtering box, and the dry filtering box slides on the upper surface of the roller to realize moving in and out operation.

[0042] Preferably,

[0043] The side sealing plate is provided with the side sealing edge; or / and:

[0044] The bag filtering frame connected to the side sealing plate is provided with the side sealing edge.

[0045] It should be noted that,

[0046] The side sealing edge can be directly designed on the side sealing plate, or can be designed separately on the side bag frame or other structural members.

[0047] Preferably,

[0048] The upper surface of the side sealing edge is provided with a side sealing plane.

[0049] The side sealing plane is integrally connected to the side extension plane downward or obliquely downward on both sides.

[0050] It should be noted that,

[0051] The side sealing edge is used for lap sealing with the side elastic sealing body of the dry filtering box, and also for smoothly preventing blocking during the pushing operation.

[0052] The side extension plane is used for increasing the strength of the side sealing edge and preventing deformation after bearing the heavy dry filtering box.

[0053] The side sealing edge is mainly used for sealing the lower air outlet dry filtering module and the dry filtering box; the dry filtering box is borne at the bottom, and during the moving in and out operation of the dry filtering box with hundreds of kilograms of weight after absorbing paint, it can not only smoothly slide, but also can ensure that the lap sealing is tight, which is extremely difficult.

[0054] In addition, the roller groove is matched with the rotating opening design of the roller, which is larger than the rotating peripheral size of the roller, and air leakage easily occurs at the opening of the roller groove, resulting in overflow of paint mist; in order to facilitate the passage of the dry filter box through the roller, the upper surface of the side sealing edge is lower than the upper surface of the roller, and the dry filter box and the side sealing edge are not in hard contact, which can ensure the smooth passage of the dry filter box; meanwhile, the lower surface of the metal or wood of the hard structure at the bottom of the dry filter box is designed with the side elastic sealing body which is connected firmly and will not fall off, fills the gap between the side sealing edge and the roller and has a redundant amount, and in the sliding process of the dry filter box, the side elastic sealing body realizes sealing in the process of contacting and being pressed by the sealing edge structure, and the sliding resistance of the side elastic sealing body connected with the metal material of the upper surface of the side sealing edge is small, which does not affect the smoothness of the passage. Therefore, the smooth sliding of the dry filter box and the sealing effect of the bottom side can be effectively ensured.

[0055] Preferably,

[0056] The bag filter frame includes a side bag frame and a front bag frame.

[0057] The side bag frame and the front bag frame are respectively provided with a planar structure, and the horizontal heights of the planar structures are the same.

[0059] The side bag frame and the front bag frame are respectively directly integrated on the side sealing plate and the front sealing plate.

[0060] It should be noted that,

[0061] The bag filter frame is used for carrying a bag filter; the side bag frame and the front bag frame are designed as the planar structures with the same height, which are tightly overlapped when the bag filter frame is carried, so as to prevent air leakage.

[0062] The positive pressure of the paint mist airflow is from top to bottom, the support structure of the bag filter is in the lower plane, under the double downward forces of the airflow and gravity, the positive pressure paint mist airflow will press the planar structure of the bag filter frame more and more tightly downward, so as to avoid air leakage.

[0063] The bag filter frame is mainly used for arranging an integrated bag filter, and the bag filter is connected to the dry filter box at the shortest distance for precise filtration, which is more conducive to the cleaning of the paint mist airflow at the rear end and further avoids the pollution of the air pipe and the fan by the paint mist.

[0064] The bag filter frame is arranged in horizontal direction, reducing air resistance and making air flow more smooth.

[0065] The bag filter frame is provided with a frame and a support, preventing the whole bag filter frame from deforming and causing air leakage.

[0066] The supports of the bag filter frame are designed at the same horizontal height, and the bag filter frame is in full contact with the support structure, avoiding air leakage.

[0067] The flat structure of the bag filter frame bears the bag filter with elastic sealing, and high-pressure paint mist flows downward, making the bag filter frame and the bag filter with elastic sealing more compact, preventing air leakage.

[0068] Preferably,

[0069] Each side sealing plate with the side sealing edge is divided into two functional areas, including a sealing area and a bearing sliding area, in the plane centering on the forward direction of the dry filter box; or / and:

[0070] Each bag filter frame with the side sealing edge is divided into two functional areas, including a sealing area and a bearing sliding area, in the plane centering on the forward direction of the dry filter box;

[0071] The side sealing edge is arranged in the sealing area;

[0072] The roller of the sliding device is arranged in the bearing sliding area.

[0073] It should be noted that,

[0074] The side sealing plate and each side frame of the dry filter box are respectively divided into two functional areas, which are sealing and bearing sliding, respectively independent, and can realize sealing after the dry filter box is moved in and out during replacement and sliding.

[0075] The sealing area and the bearing sliding area of the side sealing edge can realize sealing after the dry filter box is moved in and out during replacement and sliding.

[0076] Preferably,

[0077] The sealing area is close to the inner side of the dry filter box;

[0078] The bearing sliding area is close to the outer side of the dry filter box;

[0079] The upper surface of the sliding device and the roller is higher than the upper surface of the side sealing edge and the front sealing edge, respectively;

[0080] The upper surface of the sliding device and the side surface of the sealing area and the height difference of the upper surface of the sealing area are used to arrange the side surface elastic sealing body.

[0081] It should be noted that,

[0082] The sealing area is designed on the inner side, and the bearing sliding area is designed on the outer side, so as to prevent air leakage from the joint of the roller, the roller groove and the dry filter box to the workshop.

[0083] Preferably,

[0084] The dry filter box comprises an elastic sealing body;

[0085] The elastic sealing body comprises a side surface elastic sealing body and a front surface elastic sealing body;

[0086] The dry filter box comprises a side surface lower frame and a front surface lower frame;

[0087] The side surface lower frame is connected with the side surface elastic sealing body;

[0088] The front surface lower frame is connected with the front surface elastic sealing body;

[0089] The side surface lower frame of the dry filter box is provided with a box sealing area on the inner side and a box bearing sliding area on the outer side, with the front direction of the dry filter box as the center.

[0090] It should be noted that,

[0091] The dry filter box is provided with a sealing area and a sliding bearing area by partitioning, which realizes the dual functions of bearing sliding and sealing in cooperation with the dry filter module of the lower air outlet.

[0092] Preferably,

[0093] The side surface sealing area is overlapped with the side surface elastic sealing body of the box sealing area for sliding and sealing;

[0094] The front surface sealing area is overlapped with the front surface elastic sealing body of the front surface lower frame for sliding and sealing;

[0095] The side surface elastic sealing body and the front surface elastic sealing body are provided with a redundant height.

[0096] It should be noted that,

[0097] The purpose of providing the elastic sealing body with a redundant height is to make the sealing more tight after the stress height compression produces deformation and overlaps with the sealing area structure.

[0098] Preferably,

[0099] The front surface sealing plate is provided with a front surface sealing area;

[0100] The positive sealing plane is integrally connected to the positive extension plane extending outwardly and downwardly;

[0101] The positive sealing edge is provided with the positive sealing plane at the top;

[0102] The positive sealing edge comprises the positive sealing plane, the positive extension plane and the longitudinal plane.

[0103] It should be noted that,

[0104] The positive sealing edge is used to overlap and seal with the positive elastic sealing body of the dry filter box, and to prevent the dry filter box from being blocked during the pushing process.

[0105] The positive sealing edge structure is mainly used for sealing the dry filter box and the dry filter module of the lower air outlet. The dry filter box is supported and carried at the bottom. After the dry filter box is filled with paint and the weight increases by hundreds of kilograms, the dry filter box needs to pass above the positive sealing edge structure first and then be sealed. It can not only ensure smooth passing, but also ensure tight overlap sealing, which is extremely difficult.

[0106] The surface of the positive sealing edge is made of metal material, and an elastic sealing body is arranged at the bottom of the dry filter box. The metal and the elastic sealing body which is not affected by strong pressure are used to overlap and press to seal, and the metal and the elastic sealing body can slide smoothly.

[0107] Preferably,

[0108] The positive extension plane is further connected to the longitudinal plane downwardly or obliquely downwardly;

[0109] The positive extension plane is designed with an inclined plane or an arc-shaped plane;

[0110] The connection point of the positive extension plane and the positive sealing plane is higher than the connection point of the positive extension plane and the longitudinal plane.

[0111] It should be noted that,

[0112] The positive sealing plane is used to overlap and seal with the positive elastic sealing body of the dry filter box. The positive sealing plane is provided with a certain width, and the overlapping surface of the positive sealing plane and the positive elastic sealing body is large enough to avoid incomplete overlap caused by errors or deviations and air leakage.

[0113] The front extension surface is designed as a certain slope or arc surface, and the height is lower than the front sealing plane, so that when the hard structure of the front lower frame of the dry filter box starts to overlap with the front extension surface during the pushing process of the dry filter box, the overlap is first at a low position and then at a high position, which has a certain guiding effect and ensures smooth pushing, preventing obstruction.

[0114] Under the action of the self-weight force of the dry filter box, the elastic sealing body of the dry filter box overlaps vertically downward, and the self-weight force of the dry filter box can overcome the elastic force of the elastic sealing body and further compress the sealing structure.

[0115] The positive pressure of the paint mist airflow is from top to bottom, and the bearing structure, the side sealing edge and the front sealing edge of the dry filter box are all below the dry filter box, so that the positive pressure of the paint mist airflow compresses the plane structure of the sealing edge structure more tightly, avoiding air leakage.

[0116] The longitudinal surface has two effects, one is to increase the strength of the front extension surface, and the other is to prevent the front edge of the single plate of the front extension surface from scratching personnel during the replacement operation of the dry filter box and the bag filter.

[0117] Preferably,

[0118] The front sealing edge and the front sealing plane are lower than the lower surface of the hard structure at the bottom of the front lower frame of the dry filter box.

[0119] The height difference between the front sealing edge and the front sealing plane and the lower surface of the hard structure at the bottom of the dry filter box is used to arrange the front elastic sealing body.

[0120] Preferably,

[0121] The side sealing edge and the side sealing plane are lower than the lower surface of the hard structure at the bottom of the side lower frame of the dry filter box.

[0122] The height difference between the side sealing edge and the side sealing plane and the lower surface of the hard structure at the bottom of the dry filter box is used to arrange the front and side elastic sealing body.

[0123] It should be noted that,

[0124] The height of the front sealing edge and the front sealing plane is lower than the lower surface of the hard structure at the bottom of the front lower frame of the dry filter box, leaving a gap, so that during the overlap sliding process of the front elastic sealing body of the front lower frame and the front sealing edge, the front elastic sealing body with redundant height and high elasticity is overlapped and compressed for sealing.

[0125] Conversely, the side sealing edge and the lower surface of the bottom hard structure of the front lower frame of the dry filter box leave a gap, and the purpose of the design is to overlap and compress the front elastic sealing body with redundant height and high elasticity for sealing.

[0126] The sealing edge structure is extremely critical for the dry filter box and the sealing area of the box. For the dry filter module with up and down ventilation, the weight and load of the dry filter box are on the bottom, and during the moving in and out operation after the dry filter box absorbs hundreds of kilograms of paint, it not only needs to pass smoothly, but also needs to ensure that the dry filter box is tightly sealed at the bottom of the front. It is extremely difficult.

[0127] For easy maintenance, the roller and the roller groove are designed to be detachable, and the front sealing edge and the side sealing edge are multi-connected and non-integral structure. Due to the fact that the side sealing plate and the front sealing plate are folded several times, there may be some size errors. The upper surfaces of the side sealing edge and the front sealing edge can be kept consistent in the height direction, which is also very difficult.

[0128] The dry filter box is generally a wooden frame with a circle of wood connected as a whole around the bottom. The wood is rough, and the dry filter box bears the weight on the wooden frame. The sealing edge structure is made of metal, which is smooth. Both are hard materials for sliding connection, and enough space must be left, otherwise the gap will be too large or too small to be stuck.

[0129] By designing the metal sealing edge structure, the elastic sealing body designed at the bottom of the dry filter box is overlapped and sealed, which can effectively ensure the sealing. The rough wooden surface connects the flexible characteristics of the elastic sealing body with a certain elastic compression space, which is converted into the sliding compression of metal and the elastic sealing body. The sealing effect is good and the sliding is not blocked.

[0130] The sealing surface of the dry filter box and the elastic sealing body and the contact surface of the dry filter box and the roller are designed independently, respectively, to prevent the elastic sealing body with redundant height from contacting the roller and affecting the smoothness of the dry filter box passing on the upper surface of the roller.

[0131] Therefore, the load, sliding and sealing can be independent of each other and do not interfere with each other, which can realize sealing and smooth passing. The sealing surface of the elastic sealing body is designed on the inner side, which effectively intercepts the paint mist from overflowing to the roller groove and the roller body adhering to the paint mist.

[0132] Meanwhile, a flexible sealing plate extending downward is matched around the bottom of the dry filter box, further preventing the connection between the sealing edge structure and the elastic sealing body from sticking to paint mist.

[0133] Preferably,

[0134] The sealing edge structure overlaps and slides with the elastic sealing body at the bottom of the dry filter box and is sealed;

[0135] The side sealing edge overlaps and slides with the side elastic sealing body of the box sealing area of the lower frame on the side of the dry filter box and is sealed;

[0136] The front sealing edge overlaps and slides with the front elastic sealing body of the box bearing sliding area of the front lower frame of the dry filter box and is sealed.

[0137] Preferably,

[0138] The side sealing plate and the front sealing plate are respectively an integral structure plate, the body plate has no splicing, and has multiple functions.

[0139] It should be noted that,

[0140] The side bag frame with the side sealing edge is connected to the side sealing plate and the roller groove to form an integral structure, and can be easily disassembled for maintenance.

[0141] The side sealing plate and the front sealing plate serve as the enclosure of the ventilation channel and are respectively processed from a plate, and the whole plate does not need to be welded or connected, avoiding welding deformation and the risks of connection size error and connection sealing.

[0142] The side sealing plate and the front sealing plate are fixed through the multi-hole connection at the longitudinal connection of the four corners, and then welded, ensuring the accuracy of the connection.

[0143] The side sealing plate can also bear the roller groove and the roller, can install and fix multiple guide wheels, can connect the side bag frame and bear the bag filter, and can overlap and seal with the side elastic sealing body at the bottom of the dry filter box through the side sealing edge of the side bag frame, and can be connected and fixed with the frame sealing structure.

[0144] The front sealing plate is designed with the front sealing edge on the upper surface and the bearing flat structure of the front bag frame of the bag filter, and the front surface of the front sealing plate does not need to be holed, avoiding the risk of paint mist and air leakage.

[0145] Preferably,

[0146] The side bag frame with the side sealing edge is connected to the side sealing plate and the roller groove to form an integral structure, and can be easily disassembled.

[0147] It should be noted that,

[0148] The ventilation area of the side sealing plate is connected to the sliding device and the side bag frame through at least two holes on one side, and the number of holes in the ventilation channel is reduced, thereby reducing the risk of paint mist overflowing through the holes.

[0149] Preferably,

[0150] The side sealing plate is provided with a plurality of openings along the length direction for mounting guide wheels.

[0151] It should be noted that,

[0152] It can be understood that a plurality of guide wheels are installed on the two sides along the direction of moving in and out of the dry filter box, which are used for precise guidance of the dry filter box, avoiding skewing to cause smooth pushing or deviation from the upper air inlet dry filter module, which is easy to cause air leakage.

[0153] The lower surface of the dry filter box is tightly attached to the guide, and the guide has guide wheels installed in the openings of the side sealing plate; a plurality of guide wheels are arranged equidistantly along the side of the channel of the dry filter box; the guide wheels ensure that the dry filter box does not deviate during forward and backward movement, and moves in parallel with the upper air inlet dry filter module, ensuring the best sealing effect of the dry filter box and the smoothest movement; the arrangement of the first group of guide wheels on both sides of the inlet end of the side sealing plate is designed to be outwardly open at a certain distance, and combined with the guidance and precise positioning of the guide of the bearing framework, it is beneficial to the smooth pushing of the dry filter box during the initial pushing process.

[0154] Preferably,

[0155] The bottom of the side sealing plate and the front sealing plate is respectively provided with a folding plate with a certain angle of inclination, and the inclined surface of the folding plate is lapped with the plane of the air outlet below.

[0156] Or: the bottom of each side sealing plate and front sealing plate is provided with a downward longitudinal plate, and the longitudinal plate is provided with an inward extension surface for lapping with the air outlet below.

[0157] It should be noted that,

[0158] The function of the folding plate is to balance and adjust the error caused by the double hard connection of the connection of the bearing framework to the side sealing plate and the front sealing plate, and the connection of the folding plate to the air outlet; and the inclined surface of the folding plate is simple to weld with the plane of the air outlet, has good welding effect, and good sealing performance.

[0159] The bearing framework bears the first contact surface of the sealing plate in the height direction, and the folding plate has a second contact surface with the lower air outlet, and if the two contact surfaces have a height tolerance, the following problems are prone to occur.

[0160] The contact surface between the sealing plate and the bearing framework has a gap, so that the bearing framework cannot be fully stressed as a whole or partially stressed, the folding plate directly falls on the lower air outlet, the lower air outlet is passively stressed, the bearing framework is not stressed, the lower air outlet is originally a ventilation channel and does not have sufficient strength to bear the whole dry filter module, so that the lower air outlet is prone to deformation and air leakage after being stressed.

[0161] Alternatively, the sealing plate completely falls on the bearing framework, and the folding plate and the lower air outlet are connected by a hard structure, and the connection between the two may have a gap, so that welding is difficult and air leakage is prone to occur.

[0162] In addition, any error may cause errors between the upper air inlet dry filter module, the lower air outlet dry filter module and the dry filter box, and the overall error, which affects the sealing performance.

[0163] The two connection modes are designed based on the structure and connection mode of the bearing framework of the dry filter module and the ground, platform and air pipe, and the final design purpose is to ensure that the absolute position of the dry filter module is more accurate, the connection error is minimized, and the sealing performance is best.

[0164] In summary, the design focus of the technical scheme of the application and the main beneficial effects brought about by the technical scheme are summarized.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0264] Referring to the drawings Figures 1 to 11 As shown in the drawings, the present application provides a structure schematic view of a lower air outlet dry filter module and sealing structure for up and down ventilation.

[0265] The lower air outlet dry filter module 200 comprises an enclosure plate 1, a bearing framework 2, a sliding device 3, a guide 4, a sealing edge structure 5, and a bag filter frame 7.

[0266] The enclosure plate 1 comprises a side enclosure plate 11 and a front enclosure plate 12.

[0267] The side enclosure plate 11 and the front enclosure plate 12 are connected together to form a surrounding body 13 of the paint mist airtight ventilation channel, and are connected firmly after accurate positioning.

[0268] The sealing edge structure 5 comprises a side sealing edge 51 and a front sealing edge 54.

[0269] The side sealing edge 51 is arranged in a sealing area 52 and overlaps and seals with an elastic sealing body 81 of the dry filter box 8.

[0270] The sliding device 3 is arranged in the bearing sliding area 53, and bears and drives the dry filter box 8 to slide;

[0271] The lower air outlet dry filter module 200 bears the dry filter box 8, and the dry filter box 8 of the upper air inlet dry filter module 100 is centrally aligned up and down, so that the dry filter box 8 can be smoothly moved in and out, and the connection is tightly sealed.

[0272] The dry filter box 8 is sealed by the side sealing edge 51 and the front sealing edge 52, and is borne and driven by the sliding device 3 to slide, so that the dry filter box 8 can realize the dual functions of sealing and bearing sliding.

[0273] The lower air outlet dry filter module 200 bears the dry filter box 8 from below, and the upper air inlet dry filter module 100 limits the dry filter box 8 from above, so that the dry filter box 8 is centrally aligned, and the dry filter box 8 can be smoothly moved in and out, and the connection is tightly sealed.

[0274] In example one, with reference to the accompanying Figure 1 .

[0275] A set of dry filter modules are configured to connect two opposite dry filter boxes 8, and the two dry filter boxes 8 are connected by the frame sealing structure 9, and the frame sealing structure 9 is connected by a single plate clamping sealing rubber strip.

[0276] Further,

[0277] The side sealing plate 11 bears the sliding device 3;

[0278] The sliding device 3 includes a roller groove 31 and a roller 32;

[0279] The roller 32 bears and drives the dry filter box 8 to slide.

[0280] The bearing framework 2 bears the body of the side sealing plate 11 and the front sealing plate 12 and all structures borne thereon;

[0281] The sliding device 3, the roller groove 31 and the roller 32 are respectively detachable structures, which are convenient for maintenance of the roller 32;

[0282] The bearing framework 2 is designed with an inner small and outer expanded guide edge 21 at the inlet and outlet of the dry filter box 8.

[0283] Example two, refer to the attached Figure 1 .

[0284] The carrying skeleton 2 is used to carry the whole dry filtering module and the dry filtering box 8 with increased weight after absorbing paint; the carrying skeleton 2 carries the side sealing plate 11 and the front sealing plate 12, the side sealing plate 11 carries the roller groove 31, the roller groove 31 carries the roller 32, the roller 32 carries the dry filtering box 8, and the dry filtering box 8 slides on the surface of the roller 32 to realize the moving-in and moving-out operation;

[0285] The connection part of the roller groove 31 and the roller 32 must have a gap to facilitate the rotation of the roller 32, and the gap will cause air leakage.

[0286] Refer to the attached Figure 2 , attached Figure 10 .

[0287] The bottom of the box carrying sliding area 822 of the side lower frame 82 of the dry filtering box 8 falls on the roller 32, and the dry filtering box 8 can slide on the surface of the roller 32. The side elastic sealing body 811 of the dry filtering box 8 is connected to the box sealing area 821 of the side lower frame 82 of the dry filtering box 8, the side elastic sealing body 811 is overlapped with the side sealing edge 51, and the side elastic sealing body 811 is provided with a redundant height in addition to being completely overlapped with the side sealing edge 51 to fill the height gap. During the sliding process of the dry filtering box 8, the self-weight of the dry filtering box 8 presses the side elastic sealing body 811 with the redundant height downward, so that the dry filtering box 8 is not lifted due to the redundant height of the side elastic sealing body 811, and the whole dry filtering box 8 is stressed on the upper surface of the roller 32.

[0288] The side elastic sealing body 811 adopts a flat sealing gasket with large elasticity, which is firmly fixed on the bottom hard structure of the dry filtering box 8 by a gun nail.

[0289] The position of the gun nail avoids the area overlapped with the side sealing edge 51, so that the height difference between the dry filtering box 8 and the side sealing edge 51 is not affected by the height of the gun nail.

[0290] The side sealing plate 11 and the sliding device 3, and all the structure carried by the side sealing plate 11, are designed as a modular module as a whole, which has good overall strength, small error, uniform stress, convenient processing and manufacturing, and simplifies the installation on site.

[0291] Refer to the attached Figure 1 , attached Figure 7 .

[0292] Two groups of side sealing plates 11 and two groups of front sealing plates 12 are arranged in the carrying framework 2, and are integrally surrounded inside the carrying framework 2. After accurate connection through the reserved bolt holes 17, full welding is performed to prevent air leakage and increase strength. The integrally surrounded side sealing plates 11 and front sealing plates 12 are collectively placed on the upper frame of the carrying framework 2 to form a whole. Next, the roller cylinder 32 is connected to the roller cylinder groove 31, and then the roller cylinder groove 31 with the roller cylinder 32 is arranged on the planar area of the side sealing plate 11. The bag type filter frame 71 is attached to the side of the roller cylinder groove 31. Each side is integrally connected to the side bag type frame 71, the roller cylinder groove 31, and the side sealing plate 11 through at least two bolts. Finally, the guide wheel 41 of the side sealing plate 11 is connected and fixed. In this way, the modular module is formed as a whole, which is transported as a whole and installed on site as a whole to avoid errors in production assembly and on-site installation. When the side sealing plate and the front sealing plate are arranged inside the carrying framework 2 and welded, they become an integral whole and cannot be removed. However, the roller cylinder groove 31 and the roller cylinder 32 can be removed for maintenance of the roller cylinder 32.

[0293] The carrying framework 2 is designed with an inwardly expanding guide rail 21 at the inlet and outlet ends of the dry filter box 8, mainly to facilitate accurate docking of the dry filter box 8 with the dry filter module as a whole. The dry filter box 8 is arranged on a carrying trolley, and the bottom wheels of the carrying trolley are limited and guided by the guide rail 21 to guide the dry filter box 8. When the dry filter box 8 is initially pushed, the carrying trolley is accurately positioned under the action of the guide rail 21, can smoothly overlap the front sealing rail 54, and accurately travels in the channel under the secondary guiding action of the guide wheel 41 to prevent the dry filter box 8 from being stuck.

[0294] The sliding device 3, the roller cylinder groove 31, and the roller cylinder 32 are respectively detachable structures for easy maintenance of the roller cylinder.

[0295] Referring to the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , the accompanying drawings Figure 6 .

[0296] The roller cylinder groove 31 of the sliding device 3 is designed as a U-shaped groove structure with a flat bottom that falls on the carrying plane of the side sealing plate 11 for overall carrying. The upper part of the roller cylinder groove 31 is designed with an opening for sliding the roller cylinder 32. The overall sliding device 3 is integrally connected with the side sealing plate 11 and the side bag type frame 71 through concentric holes to form an integral structure. The bag type filter frame 71, the sliding device 3, and the side sealing plate 11 are respectively detachable.

[0297] Further,

[0298] The side sealing plate 11 is provided with a side sealing rail 51.

[0299] Or / and:

[0300] The bag filter frame 7 connected with the side sealing plate 11 is provided with a side sealing edge 51.

[0303] The side sealing edge 51 is designed on the side bag frame 71, and the sealing edge and the bag frame are connected and can be detached. The bag frame is designed with a flat structure 74.

[0304] In addition, the roller groove 31 is matched with the rotating opening of the roller 32, and the opening of the roller groove 31 is designed to be larger than the rotating peripheral size of the roller 32, so that the paint mist is easily leaked and overflowed; in order to facilitate the bearing of the dry filter box 8 by the roller 32, the upper surface of the side sealing edge 51 is lower than the upper surface of the roller 32, and a certain gap is left, so that the dry filter box 8 and the side sealing edge 51 are not in hard contact, and the smooth passing of the dry filter box 8 can be ensured; at the same time, the lower surface of the metal or wood hard structure of the bottom of the dry filter box 8 is designed with a side elastic sealing body 811 which is connected firmly and will not fall off, and fills the gap between the side sealing edge 51 and the roller 32 and is designed with a redundant amount, so that in the process of sliding of the dry filter box 8, the side elastic sealing body 811 realizes sealing in the process of being in contact with the sealing edge structure 5 and being pressed, and the sliding resistance of the side elastic sealing body 811 in the process of being connected with the metal material of the upper surface of the side sealing edge 51 is very small, which does not affect the smoothness of passing. Therefore, the smooth sliding of the dry filter box 8 and the sealing effect of the bottom side can be effectively ensured.

[0305] The side elastic sealing body 811 adopts a 3-5mm flat sealing gasket.

[0306] The side elastic sealing body 811 adopts a gas nail gun to punch metal nails onto the hard structure, and the hard structure is made of wood. The number of nails is 30-50mm, and is uniformly arranged and staggered left and right. The number of nails is large, which prevents the side elastic sealing body 811 from separating from the wood or the wood.

[0307] Further,

[0308] The side sealing edge 51 is provided with a side sealing plane 511 on the upper surface.

[0309] The side sealing plane 511 is integrally connected with a side extension plane 512 downward or obliquely downward on both sides.

[0310] It should be noted that,

[0312] Side sealing edge 51, mainly used for sealing of the lower air outlet dry filter module 200 and the dry filter box 8; the dry filter box 8 is supported at the bottom, and during the operation of moving in and out of the dry filter box 8 with hundreds of kilograms of weight increase due to paint absorption, it can not only smoothly slide, but also ensure that the lap sealing is tight, which is extremely difficult;

[0313] The function of the side sealing edge 51 is to lap seal with the side elastic sealing body 811 of the dry filter box 8, and to prevent obstruction and jam during the pushing process;

[0314] The function of the side extension surface 512 is to increase the strength of the side sealing edge 51 to prevent deformation after bearing the heavy dry filter box 8.

[0315] Further,

[0316] The bag filter frame 7 includes a side bag frame 71 and a front bag frame 72;

[0317] The side bag frame 71 and the front bag frame 72 are respectively provided with a planar structure 74, and the horizontal height of the planar structure 74 is the same;

[0318] The side bag frame 71 and the front bag frame 72 are respectively independently designed; or / and:

[0319] The side bag frame 71 and the front bag frame 72 are respectively directly integrated on the side sealing plate 11 and the front sealing plate 12.

[0320] It should be noted that,

Therefore, under the double downward forces of the airflow and the gravity, the positive pressure paint mist airflow will press the planar structure 74 of the bag filter frame 7 downward more tightly, avoiding air leakage.

[0324] The bag filter frame 7 is used for arranging the integrated bag filter 75. The bag filter 75 is connected to the dry filter box 8 at the shortest distance, which is used for precise filtration, and is more conducive to the cleanliness of the rear end paint mist airflow, further avoiding the pollution of the air pipe and the fan by the paint mist.

[0326] The bag filter frame 7 is provided with a frame and a support around the bag filter frame 7 to prevent the bag filter frame 7 from deforming as a whole and causing air leakage.

[0327] The support of the bag filter frame 7 is designed at the same horizontal height, and the bag filter frame 7 is in full contact with the support structure to avoid air leakage.

[0328] The flat bearing of the bag filter frame 7 is provided with an elastic sealed bag filter 75, and the high-pressure paint mist flows downward, so that the bag filter frame 7 and the elastic sealed bag filter 75 are pressed more tightly to prevent air leakage.

[0329] Further,

[0330] Each side sealing plate 11 with a side sealing edge 51 is divided into two functional areas in the plane, including a sealing area 52 and a bearing sliding area 53, with the front direction of the dry filter box 8 as the center; or / and:

[0331] Each bag filter frame 7 with a side sealing edge 51 is divided into two functional areas in the plane, including a sealing area 52 and a bearing sliding area 53, with the front direction of the dry filter box 8 as the center.

[0332] The side sealing edge 51 is arranged in the sealing area 52.

[0333] The roller 32 is arranged in the bearing sliding area 53.

[0334] It should be noted that,

[0335] In the sixth embodiment, with reference to the accompanying Figure 4 .

[0336] Each side lower frame 82 of the dry filter box 8 is divided into two functional areas in the plane along the length direction, including a box sealing area 821 and a box bearing sliding area 822.

[0337] The box sealing area 821 is close to the inner side of the dry filter box 8.

[0338] The box bearing sliding area 822 is close to the outer side of the dry filter box 8.

[0339] The box sealing area 821 falls on the side sealing edge 51 of the sealing area 52 for sealing.

[0340] The box bearing sliding area 822 falls above the roller 32 corresponding to the bearing sliding area 53 for bearing and sliding.

[0341] It should be noted that,

[0342] The dry filtering box is provided with a partition, and cooperates with the sealing area and the sliding bearing area of the dry filtering module of the lower air outlet to realize the double functions of bearing sliding and sealing.

[0343] The side sealing plate 11 and each side lower frame 82 of the dry filtering box 8 are respectively divided into two functional areas, that is, sealing and bearing sliding are respectively independent, and the dry filtering box 8 can realize sealing after being moved in and out during replacement and sliding.

[0344] The dry filtering box 8 cooperates with the sealing area 52 and the bearing sliding area 53 of the side sealing edge 51 to realize the sealing of the dry filtering box 8 after being moved in and out during replacement and sliding.

[0345] Further,

[0346] The sealing area 52 is close to the inner side of the dry filtering box 8.

[0347] The bearing sliding area 53 is close to the outer side of the dry filtering box 8.

[0348] The upper surface of the sliding device 3 is higher than the upper surfaces of the side sealing edge 51 and the front sealing edge 54.

[0349] It should be noted that,

[0350] In the seventh embodiment, the upper surface of the roller 32 is higher than the upper surface of the side sealing edge 51. Figure 2 .

[0351] The upper surface of the roller 32 is higher than the upper surface of the side sealing edge 51.

[0352] The height difference between the upper surface of the sliding device 3 and the upper surface of the side sealing edge 51 is used to arrange the side elastic sealing body 811.

[0353] The sealing area 52 is designed on the inner side, and the bearing sliding area 53 is designed on the outer side, so as to prevent air leakage from the joint of the roller 32, the roller groove 31 and the dry filtering box 8 to the workshop.

[0354] Further,

[0355] The dry filtering box 8 comprises an elastic sealing body 81.

[0356] The elastic sealing body 81 comprises a side elastic sealing body 811 and a front elastic sealing body 812.

[0357] The dry filtering box 8 comprises a side lower frame 82 and a front lower frame 83.

[0358] The side lower frame 82 is connected with the side elastic sealing body 811.

[0359] The front lower frame 83 is connected with the front elastic sealing body 812.

[0360] The side lower frame 82 of the dry filter box 8 is provided with a box sealing area 821 on the inner side and a box bearing sliding area 822 on the outer side, with the front direction of the dry filter box 8 as the center.

[0361] Further,

[0362] The side sealing edge 51 slides and seals with the side elastic sealing body 811 of the box sealing area 821;

[0363] The front sealing edge 54 slides and seals with the front elastic sealing body 812 of the front lower frame 83;

[0364] The side elastic sealing body 811 and the front elastic sealing body 812 are provided with a redundant height.

[0365] It should be noted that,

[0366] The elastic sealing body 81 is provided with a redundant height, and after the stress height is compressed to deform, it is more tightly sealed with the sealing edge structure 5.

[0367] Further,

[0368] The front sealing plate 12 is provided with a front sealing edge 54;

[0369] The front sealing edge 54 includes a front sealing plane 541, a front extension plane 542, and a longitudinal plane 543.

[0370] The front sealing edge 54 is provided with a front sealing plane 541 at the top;

[0371] The front sealing plane 541 is integrally connected to the front extension plane 542 extending downward on the outside.

[0372] Embodiment eight, refer to the attached Figure 2 .

[0373] The function of the front sealing edge 54 is to seal with the front elastic sealing body 812 of the dry filter box 8, and to smoothly prevent obstruction and jamming during the pushing process.

[0374] The front sealing edge 54 is mainly used for the sealing of the dry filter box 8 and the dry filter module 200 of the lower air outlet. The dry filter box 8 is heavy and is supported at the bottom. After the dry filter box 8 absorbs paint and increases in weight by hundreds of kilograms, the dry filter box 8 needs to pass above the front sealing edge 54 of the front sealing edge 54 first, and then be sealed. It can not only ensure smooth passage, but also ensure tight sealing, which is extremely difficult.

[0375] The surface of the front sealing edge 54 is made of metal, and the bottom of the dry filter box 8 is provided with an elastic sealing body 81. The metal and the elastic sealing body 81 are overlapped and pressed to seal, and the overlapping of the metal and the elastic sealing body 81 can slide smoothly.

[0376] Further,

[0377] The front extension surface 542 is connected to the downward or obliquely downward longitudinal surface 543.

[0378] The front extension surface 542 is designed as an inclined surface or an arc surface.

[0379] The connection point of the front extension surface 542 and the front sealing surface 541 is higher than the connection point of the front extension surface 542 and the longitudinal surface 543.

[0380] It should be noted that,

[0381] Embodiment nine, referring to the attached Figure 2 .

[0382] The front sealing surface 541 is used to overlap and seal with the front elastic sealing body 812 of the dry filter box 8. The front sealing surface 541 is provided with a certain width, and the overlapping surface of the front sealing surface 541 and the front elastic sealing body 812 is large enough to avoid incomplete overlapping caused by errors or deviations, which may cause air leakage.

[0383] The front extension surface 542 is designed as an inclined surface or an arc surface, and the height of the front extension surface 542 is lower than that of the front sealing surface 541. The purpose is that when the hard structure of the front lower frame 83 of the dry filter box 8 starts to overlap with the front extension surface 542 during the pushing process of the dry filter box 8, the overlapping starts from the low position and then moves to the high position, which has a certain guiding effect, ensuring that the dry filter box 8 can be smoothly pushed and prevented from being blocked.

[0384] Under the action of the self-weight force of the dry filter box 8, the elastic sealing body 81 of the dry filter box 8 overlaps vertically downward, and the self-weight force of the dry filter box 8 can overcome the elastic force of the elastic sealing body 81 and then press the sealing edge structure 5.

[0385] The positive pressure of the paint mist airflow is from top to bottom. The bearing structure, the side sealing edge 51 and the front sealing edge 54 of the dry filter box 8 are all below the dry filter box 8. The positive pressure of the paint mist airflow is more and more tight to the plane structure 74 of the sealing edge structure 5, which avoids air leakage.

[0386] The longitudinal surface 543 has two functions. One is to increase the strength of the front extension surface 542, and the other is to prevent the front edge of the single plate of the front extension surface 542 from scratching the personnel during the replacement operation of the dry filter box 8 and the bag filter 75.

[0387] Further,

[0388] The front sealing edge 54 and the front sealing plane 541 are lower than the lower surface of the bottom hard structure of the front lower frame 83 of the dry filter box 8.

[0389] It should be noted that,

[0390] The height difference between the front sealing edge 54 and the front sealing plane 541 and the lower surface of the bottom hard structure of the dry filter box 8 is used to arrange the front elastic sealing body 812.

[0391] Further,

[0392] The side sealing edge 51 and the side sealing plane 511 are lower than the lower surface of the bottom hard structure of the side lower frame 82 of the dry filter box 8.

[0393] It should be noted that,

[0394] The height difference between the side sealing edge 51 and the side sealing plane 511 and the lower surface of the bottom hard structure of the dry filter box 8 is used to arrange the side elastic sealing body 811.

[0395] Embodiment ten, referring to the attached Figure 2 , attached Figure 3 .

[0396] The height of the front sealing edge 54 and the front sealing plane 541 is lower than the lower surface of the bottom hard structure of the front lower frame 83 of the dry filter box 8, leaving a gap, the purpose is that the front elastic sealing body 812 of the front lower frame 83 will be sealed after being overlapped and compressed with the front sealing edge 54 during the overlapping sliding process.

[0397] On the contrary, the height of the side sealing edge 51 and the side sealing plane 511 is lower than the lower surface of the bottom hard structure of the front lower frame 83 of the dry filter box 8, leaving a gap, the purpose of the design is to seal the side elastic sealing body 811 after being overlapped and compressed with a redundant height and high elasticity.

[0398] The sealing edge structure 5, combined with the box sealing area 821 of the dry filter box 8, is a very critical technology. For the up and down ventilation dry filter module, the weight and load of the dry filter box 8 are at the bottom, and during the moving in and out operation process after the dry filter box 8 absorbs paint and increases hundreds of kilograms, it not only needs to pass smoothly, but also needs to ensure that the front bottom of the dry filter box 8 is tightly sealed, which is extremely difficult.

[0399] For easy maintenance, the roller roller groove 31 and the roller roller 32 are designed to be detachable, and the front sealing edge 52 and the side sealing edge 51 are multi-connected and non-integrated structures. Due to the fact that the side sealing plate 11 and the front sealing plate 12 are folded several times respectively, there may be a certain size error. The upper surfaces of the side sealing edge 51 and the front sealing edge 51 can keep consistent in the height direction, which is also very difficult.

[0400] The dry filter box 8 is generally a wooden frame, and a circle of wood is integrally connected around the bottom. The wood is hard in structure, and the load of the dry filter box 8 is borne on the wooden frame. The wood is rough; the sealing edge structure 5 is of metal material, which is smooth; both are hard materials for sliding connection, and enough space must be left, otherwise the gap will be large or small, which will be difficult to slide.

[0401] By designing the metal sealing edge structure 5, the elastic sealing body 81 designed on the bottom of the dry filter box 8 is overlapped and sealed, which can effectively ensure the sealing. The rough wooden surface is connected and fixed with the flexible characteristic of the elastic sealing body 81 with a certain elastic compression space, which is converted into the sliding compression of metal and elastic sealing body 81, and the sealing effect is good and the sliding is not blocked.

[0402] The sealing surface of the dry filter box 8 and the elastic sealing body 81 and the contact surface of the dry filter box 8 and the roller 32 are designed independently, so as to prevent the elastic sealing body 81 with redundant height from contacting the roller 32 and affecting the smooth passing of the dry filter box 8 on the surface of the roller 32.

[0403] Therefore, the bearing, sliding and sealing can be independent of each other and do not interfere with each other, which can realize sealing and smooth passing. The sealing surface of the elastic sealing body 81 is designed on the inner side, which can effectively intercept the paint mist overflow to the roller groove 31 and the body of the roller 32.

[0404] At the same time, the flexible sealing plate extending downward is designed around the bottom of the dry filter box 8, which further prevents the paint mist from sticking at the connection between the sealing edge structure 5 and the elastic sealing body 81.

[0405] Further,

[0406] The sealing edge structure 5 and the elastic sealing body 81 on the bottom of the dry filter box 8 are overlapped and sealed;

[0407] The side sealing edge 51 and the side elastic sealing body 811 of the box sealing area 821 of the side lower frame 82 of the dry filter box 8 are overlapped and sealed;

[0408] The front sealing edge 54 and the front elastic sealing body 812 of the box bearing sliding area 822 of the front lower frame 83 of the dry filter box 8 are overlapped and sealed;

[0409] The side elastic seal body 811 and the front elastic seal body 812 are provided with a redundant height;

[0410] The purpose of providing the elastic seal body 81 with a redundant height is to make the seal more compact after the stress height is compressed.

[0411] Embodiment eleven,

[0412] Referring to the accompanying Figure 2 The side elastic seal body 811 is arranged at the bottom of the dry filter box 8.

[0413] Referring to the accompanying Figure 3 The front elastic seal body 812 is arranged at the bottom of the dry filter box 8.

[0414] Further,

[0415] The side sealing plate 11 and the front sealing plate 12 are respectively integrated structure plates, and the body plates do not have any splicing and have multiple functions.

[0416] Embodiment twelve, referring to the accompanying Figure 1 .

[0417] The side bag frame 71 with the side sealing edge 51 is connected to the side sealing plate 11 and the roller groove 31 to form an integrated structure, and can be easily disassembled for maintenance.

[0418] The side sealing plate and the front sealing plate are used as the enclosure of the ventilation channel, and are respectively processed from a plate, and the whole plate does not need to be welded or connected, so that welding deformation is avoided, and the risks of connection sealing, connection size error and the like are avoided.

[0419] The side sealing plate and the front sealing plate are fixed through the multi-hole connection at the longitudinal connection of the four corners, and then are welded, so as to ensure the connection precision.

[0420] The side sealing plate can also carry the roller groove and the roller, can install and fix a plurality of guide wheels 41, can connect the side bag frame and carry the bag filter 75, and can be sealed with the side elastic seal body 811 at the bottom of the dry filter box through the side sealing edge of the side bag frame, and can be connected and fixed with the frame sealing structure.

[0421] The front surface of the front sealing plate is designed with a front sealing edge and a carrying plane structure of the front bag frame 72 of the bag filter 75, and the front surface of the front sealing plate does not need to be punched, so that the risk of paint mist and air leakage is avoided.

[0422] Further,

[0423] The side bag frame with the side sealing edge is connected to the side sealing plate and the roller groove to form an integrated structure, and can be disassembled.

[0424] It should be noted that,

[0425] Embodiment thirteen, refer to the attached Figure 1

[0426] The ventilation area of the side sealing plate is provided with at least two openings on one side, which is connected with the sliding device and the side bag frame, and the openings of the ventilation channel are reduced, that is, the risk of overflow of paint mist through the openings is reduced.

[0427] Further,

[0428] The side sealing plate 11 is provided with a plurality of openings in the length direction for mounting the guide wheels 41.

[0429] It should be noted that,

[0430] Embodiment fourteen, refer to the attached Figure 1 , the attached Figure 7

[0431] Each dry filter box 8 is provided with five guide wheels 41 on both sides, which are uniformly arranged in the length direction, and the outer edge of the first guide wheel 41 at the entrance end of the dry filter box 8 exceeds the outside of the side sealing plate 11.

[0432] It can be understood that a plurality of guide wheels 41 are installed on both sides along the direction of movement of the dry filter box 8, which are used for accurate guidance of the dry filter box 8, to avoid skewing and causing smooth pushing, or deviation from the upper air inlet dry filter module, which is easy to cause air leakage.

[0433] The outer surface of the lower side of the dry filter box is tightly attached to the guide, and the guide is provided with guide wheels 41, which are installed in a plurality of openings of the side sealing plate; a plurality of guide wheels 41 are arranged equidistantly along the side of the channel of the dry filter box; the guide wheels 41 ensure that the dry filter box does not deviate during forward and backward movement, and moves in parallel with the upper air inlet dry filter module, to ensure that the sealing effect of the dry filter box is best and the movement is most smooth; the arrangement of the first group of guide wheels 41 on both sides of the inlet end of the side sealing plate is designed to be outwardly open at a certain distance, and the guide along the bearing framework is beneficial to the smooth pushing of the dry filter box during the initial pushing process.

[0434] Further,

[0435] It should be noted that,

[0436] Embodiment fifteen, refer to the attached Figure 8

[0437] The bottom of the side sealing plate 11 and the front sealing plate 12 is respectively provided with a certain angle of the folding plate 14, and the inclined surface of the folding plate 14 is overlapped with the lower air outlet plane.

[0438] ​​​​The role of the folded plate is to balance the error caused by the double hard connection of the connection of the bearing framework, the bearing side sealing plate and the front sealing plate, and the connection of the folded plate and the air outlet. The inclined surface of the folded plate and the plane of the air outlet are simple to weld, have good welding effect and good sealing performance.

[0439] Further,

[0440] The bottom of the side sealing plate 11 and the front sealing plate 12 is provided with a downward longitudinal plate 15, and the longitudinal plate 15 is provided with an inward extension surface 16 for lapping with the lower air outlet.

[0441] The cross-sectional view of the sealing plate shows that the sealing plate is provided with a lower longitudinal plate 15 and an inward and downward extension surface 16.

[0442] It should be noted that,

[0443] Embodiment sixteen, referring to the attached Figure 9 .

[0444] The bearing framework 2 bears the sealing plate 1, which has a first contact surface in the height direction, and the folded plate 14 has a second contact surface with the lower air outlet. If there is a height error between the two lapping surfaces, the following problems may occur.

[0445] The lapping surface of the sealing plate 1 and the bearing framework 2 has a gap, which causes the bearing framework 2 to not be able to bear the whole force or part of the force, and the folded plate 14 directly falls on the lower air outlet, which is passively stressed, while the bearing framework 2 is not stressed. The lower air outlet, which is originally a ventilation channel, does not have enough strength to bear the whole dry filter module, which is easy to cause deformation and air leakage after being stressed.

[0446] Alternatively, the sealing plate 1 completely falls on the bearing framework 2, and the folded plate 14 and the lower air outlet are connected by hard material. The connection between the two has a gap, which makes the welding difficult and easy to cause air leakage.

[0447] In addition, no matter which error may cause the dry filter module and the dry filter box between the upper air inlet and the lower air outlet to have their own error and overall error, which will affect the sealing performance.

[0448] The design of the two connection methods is based on the bearing framework of the dry filter module, and the structure form and connection method adopted by the ground, platform, air pipe and the like. The final design purpose is to ensure that the absolute position of the dry filter module is more accurate, the connection error is minimized, and the sealing performance is best.
