Description

Technical Field

[0001] The invention belongs to the technical field of filtration, and in particular relates to a connection device for a filter and a filtration system. Background Art

[0002] Existing capsule filters are generally used in fluid systems in semiconductors. There are many different types of filters in the prior art, and different types of filters are mainly reflected in the different shapes of the arrangement of their multiple ports. Different types of filters need to be installed and used with specific connecting devices that match their ports when in use. The arrangement shape of the multiple joints of the specific connecting device and the arrangement shape of the multiple ports of the filter should be basically consistent. The multiple joints on the specific connecting device can be connected and sealed with the multiple ports of the filter one by one, so that the filter and the corresponding specific connecting device can be matched for installation and use.

[0003] For example, the existing patent JP4234938B2 discloses a type of capsule filter and a connecting device, and it can be seen that the multiple joints on the connecting device are roughly L-shaped, and the three ports on the top of the corresponding filter are also roughly L-shaped. For details, please refer to the drawings in the patent specification. For another example, the existing patent US7195122B2 discloses another type of capsule filter, and it can be seen that the three ports on the top of the capsule are roughly in a straight line. For details, please refer to the drawings in the patent.

[0004] In summary, different types of capsule filters can generally only be installed and used with specific connecting devices that match them. Therefore, in the fluid system of semiconductors, once different types of filters are replaced, the corresponding connecting devices must also be replaced. In this way, because the connecting devices need to be replaced, the replacement of different types of filters becomes very troublesome, time-consuming and labor-intensive. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a connection device for a filter, which can shift and configure multiple connectors into a shape matching multiple ports of the filter by moving the connectors, and radially limit the connectors on the outer peripheral side of the connectors through at least three limiting portions formed by the limiting portions of the limiting plate, so that the multiple connectors are kept in this shape and connected and sealed with the multiple ports.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a connection device for a filter, the filter having a plurality of ports, the connection device comprising a fixing member and a plurality of joints penetrating the fixing member;

[0007] The fixing member is provided with a moving hole for the joint to pass through, and the joint can move along the moving hole, and the relative positions of the plurality of joints can be changed by moving the joint, so that the plurality of joints can be configured into a plurality of forms with different shapes;

[0008] The connecting device further comprises a limiting plate, the fixing member comprises a slot layer for inserting and removing the limiting plate, the outer peripheral side of the connector comprises at least three limiting portions for radially limiting the connector, and at least one of the limiting portions is formed on the limiting plate;

[0009] The connector includes a limiting section. When the limiting plate is inserted into the slot layer, the at least three limiting portions can abut against the limiting section to limit the connector position in each form on the outer peripheral side of the connector. The multiple connectors in each form can be docked and sealed with multiple ports of the filter.

[0010] The filter connecting device provided by the present invention changes the relative positions of multiple connectors by moving the connectors in the movable holes, and can configure the multiple connectors into different forms corresponding to the shapes of the ports of different types of filters. Then, the limiting plate is inserted into the slot layer, and the limiting portion provided by the limiting plate can abut against the limiting section of the connector for radial limiting. At least three limiting portions jointly limit the movement of the connector to maintain the determined position of the connector, so that the multiple connectors on the fixing member are maintained in a form adapted to the shapes of the multiple ports of the filter to be connected, thereby realizing the docking and sealing of the multiple connectors and the multiple ports of the filter. Therefore, only by moving the connectors and limiting and fixing the limiting plates, the connecting device can be matched with different types of filters. When the connecting device is applied to a fluid system, when replacing different types of filters, there is no need to replace other connecting devices, only the connectors need to be moved and the limiting plates need to be operated, so that the connecting device can be matched with and installed with different types of filters, which is simple to operate and saves time and effort.

[0011] Preferably, a limiting groove for the connector to pass through is provided on the limiting plate along the plugging and unplugging direction, and an inner wall of the limiting groove is configured as the limiting portion.

[0012] In this way, when the limiting plate is inserted into the slot layer, the joint is also correspondingly inserted into the limiting groove. The inner wall of the limiting groove acts as a limiting portion to radially limit the joint on the outer peripheral side of the joint to keep the joint position in a desired shape, thereby allowing the joint maintained in the desired shape to be docked and sealed with the port of the filter.

[0013] Preferably, at least one limiting portion is formed as an inner wall of the movable hole, and the limiting portion of the limiting plate and the limiting portion of the movable hole jointly define the joint in each form.

[0014] In this way, when the limiting plate is inserted into the slot layer, not only the limiting plate can radially limit the joint, but also the inner wall of the movable hole can radially limit the joint. The limiting portion of the inner wall of the movable hole and the limiting portion of the limiting plate can be combined to form at least three limiting portions to jointly radially limit a single joint to keep it limited at a certain position.

[0015] Preferably, the limiting portion of the movable hole is arranged opposite to the insertion direction of the limiting plate.

[0016] With such arrangement, the limiting portion of the inner wall of the movable hole can at least limit the movement of the connector in the insertion direction, and the limiting portion of the limiting plate can limit the movement of the connector in the removal direction. Then, the inner wall of the movable hole and / or the limiting plate provide limiting portions for limiting the movement of the connector in other directions, thereby popping the connector out at a determined position.

[0017] Preferably, one of the limiting portions and another of the limiting portions are located at different heights in the vertical direction.

[0018] With such arrangement, all the limit parts are not located at the same height in the vertical direction, and the limit parts at different height positions in the vertical direction radially limit the limit sections at different height positions of the limit sections. There is no need to set all the limit parts at the same height in the vertical direction. The limit parts at different heights not only radially limit the movement of the joint, but the distance between the limit parts in the height direction can also prevent the joint from tilting vertically to a certain degree, so as to prevent excessive tilting of the joint.

[0019] Preferably, there is one limiting plate, and a plurality of limiting grooves are formed on the limiting plate, and each group of limiting grooves is used to limit the plurality of joints in each form.

[0020] With such an arrangement, multiple joints in one form are limited by the number and positions of each group of limiting grooves on a single limiting plate, without the need for multiple limiting plates, thus saving limiting plate materials.

[0021] Preferably, there are multiple limit plates in each form, and the limit grooves on the multiple limit plates are used to jointly limit the multiple joints.

[0022] With such a configuration, when the limiting groove on a single limiting plate is not sufficient to limit multiple joints in a certain form, at least one additional limiting plate is required to cooperate with the previous limiting plate. Multiple limiting plates can jointly limit multiple joints, which can reduce the design complexity of the limiting groove.

[0023] Preferably, the plurality of joints include a movable joint movably disposed in the movable hole and a positioning joint positioned on the fixing member, and the inner wall of the limiting groove can abut against the movable joint.

[0024] Such arrangement is mainly to change the relative position of the movable joint by moving the movable joint in the movable hole, and the positioning joint has a determined position on the fixing part, so the inner wall of the limiting groove can abut and limit the movement of the movable joint as a limiting part, so that the movable joint is maintained at a determined position in each form.

[0025] Preferably, at least two limiting grooves are provided on the limiting plate, and when the inner wall of one limiting groove abuts against the outer wall of the positioning joint, the inner walls of the other limiting grooves can abut against the outer wall of the movable joint.

[0026] With such a configuration, when the inner wall of a limit groove abuts against the outer wall of the positioning joint, the limit plate can no longer move further along the insertion direction, and the positioning joint stops the limit plate. At this time, the limit plate is inserted into place, and the inner wall of the limit groove can serve as a limit part to radially limit the outer wall of the movable joint.

[0027] Preferably, the movable hole includes a first movable hole and a second movable hole connected to the first movable hole, and the movable joint includes a first joint penetrating in the first movable hole and a second joint penetrating in the second movable hole.

[0028] With such arrangement, the first joint and the second joint move in the first moving hole and the second moving hole respectively, and the combined shape of the first joint, the second joint and the positioning joint constitutes different forms of a plurality of joints.

[0029] Preferably, the plurality of limiting plates in each form are stacked up and down or arranged with intervals up and down.

[0030] With such arrangement, a plurality of limit plates can be stacked up and down together, or overlapped up and down but with a gap between the upper and lower limit plates. Although a plurality of limit plates are arranged, the arrangement methods between the plurality of limit plates are various and adjustable, so as to facilitate installation.

[0031] Preferably, the inner wall of the limiting groove or the inner wall of the moving hole includes a straight section and an arc section, and the straight section and the arc section can be formed into the limiting portion.

[0032] With such an arrangement, both the straight section or the arc section can be used as a limiting portion to remove the radial limiting joint, at least a portion of the inner wall of the limiting groove or at least a portion of the inner wall of the movable hole is constructed as a limiting portion, and the arc section and the tubular limiting section are more adaptable, and the arc section and the tubular limiting section can be limited by surface contact, which will increase the limiting area of ​​the limiting section.

[0033] Preferably, one limiting plate is provided in each form, and the limiting plate is inserted into the slot layer from the front side or the upper side of the fixing member, and a limiting portion of one limiting plate in each form and a limiting portion of the movable hole define the multiple joints.

[0034] With such arrangement, only a single limit plate is used to limit the positions of multiple joints in each form, and too many limit plates are not needed. The single limit plate is inserted from the front or upper side of the fixing part, which is convenient for the operator to operate.

[0035] Preferably, the opening end of the limiting groove is provided with a guiding inclined surface for guiding the joint into the limiting groove.

[0036] With such arrangement, when the limiting plate is inserted into the slot layer along the insertion direction, when facing some joints that have not been moved into place, the guiding inclined surface cooperates with the guiding of the outer wall of the joint, so that the joint can adaptively move slightly in the moving hole, so that the joint can smoothly pass into the limiting groove and be limited.

[0037] Preferably, when the limiting plate is separated from the slot layer, the limiting plate is connected to the fixing member.

[0038] With such arrangement, the limit plate is not stored separately from the fixing part. When the limit plate is pulled out from the slot layer, the limit plate is connected to the fixing part and is kept together with the fixing part, so that when the limit plate is inserted again, there is no need to search for the limit plate separately and the limit plate can be controlled to be reinserted into the slot layer.

[0039] Preferably, the connecting device comprises a movable member for detachably mounting the filter, wherein the movable member is movably connected below the fixed member and can move up and down relative to the fixed member.

[0040] With such arrangement, the movable part can disassemble and assemble filters of different types, and the movable part drives the filter to move up and down when moving up and down, thereby achieving butt sealing between the port and the joint of the filter.

[0041] Preferably, the fixing member comprises a base plate connected to the movable member and a mounting plate arranged above the base plate, the base plate and the mounting plate are both provided with the moving holes, and the slot layer is formed on the mounting plate.

[0042] In this way, the movable holes on the mounting plate and the movable holes on the substrate are accumulated in the height direction, and the joints with a certain height pass through the movable holes on the mounting plate and the movable holes on the substrate. The mounting plate provides space for setting the slot layer so that the plug-in board and the substrate do not interfere with each other.

[0043] Preferably, the fixing member further comprises a top plate detachably arranged above the mounting plate, the top plate and the mounting plate are spaced apart to form a retaining layer, and the joint comprises a flange accommodated in the retaining layer.

[0044] With such arrangement, the retaining layer and the slot layer are located at different heights, so that the flange and the limit plate do not interfere with each other, and the flange is accommodated in the retaining layer above the slot layer. The joint is blocked by the flange and will not fall down, but will be retained on the fixing part. When the joint is worn and needs to be replaced with a new one, the entire joint can be removed from the fixing part only by removing the top plate. There is no need to separate the filter and the joint and to separate the filter from the connecting device and then remove the joint. The operation is simple and saves time and effort.

[0045] Preferably, the connecting device includes a positioning device, and the limiting plate is provided with a positioning hole that cooperates with the positioning device. When the limiting plate in the slot layer limits the multiple joints to each form, the positioning hole and the positioning device cooperate to limit the movement of the limiting plate along the plug-in and pull-out direction.

[0046] With such a configuration, when the limit plate is inserted into the slot layer and limits the position and shape of multiple joints, the cooperation between the positioning hole and the positioning device enables the limit plate to be positioned in the slot layer, and the limit plate cannot move in the plugging and unplugging direction to a certain extent, which can prevent the limit plate from moving excessively or insufficiently in the slot layer, so as to ensure that the limit part on the limit plate plays a radial limiting role on the joint.

[0047] The present invention further provides a filtering system, comprising a connecting device for a filter as described in any one of the above, and a filter capable of being sealed and connected to the connecting device.

[0048] The filtering system provided by the present invention is applied to a fluid system, and the fluid from the previous process is filtered through a filter in the filtering system and enters the next process.

[0049] The beneficial effects of the present invention are as follows: the relative positions of multiple connectors are changed by moving the connector in the movable hole, and the multiple connectors can be configured into different forms corresponding to the shapes of different types of filter ports. The limiting plate is then inserted into the slot layer, and the limiting portion provided by the limiting plate can abut against the limiting section of the connector for radial limiting. At least three limiting portions jointly limit the movement of the connector to maintain a unique position of the connector, so that the multiple connectors on the fixing member are maintained in a form that is adapted to the shapes of the multiple ports of the filter to be connected, thereby achieving docking and sealing of multiple connectors and multiple ports of the filter. Therefore, only by moving the connector and limiting and fixing the limiting plate, the connecting device can be matched with different types of filters. When the connecting device is applied to a fluid system, when replacing different types of filters, there is no need to replace other connecting devices. Only the connector needs to be moved and the limiting plate needs to be operated, so that the connecting device can be matched with and installed with different types of filters. The operation is simple and time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0069] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0070] like Figure 1-Figure 18 As shown, the present invention provides a filter connection device for connecting with different types of filters 3, the filter 3 has a plurality of ports 33, and the shapes of the plurality of ports 33 of different types of filters 3 are different, such as roughly L-shaped, straight-line, isosceles triangle, etc. Figure 17-18For example, the filter 3 is divided into a straight-line first filter 31 and an L-shaped second filter 32. The connecting device includes a fixing member 1 and a plurality of connectors 8 passing through the fixing member 1, wherein the number of connectors 8 and the number of ports 33 are generally equal.

[0071] The fixing member 1 is provided with a moving hole 11 for the joint 8 to pass through, and the joint 8 can move along the moving hole 11. The relative positions of the multiple joints 8 can be changed by moving the joint 8, so that the multiple joints 8 can be configured into various forms with different shapes. Among them, any number of joints 8 can be moved to change the relative positions of the multiple joints 8, so that the multiple joints 8 can be switched between different forms. In some embodiments, the various forms of the combination of the multiple joints 8 can be roughly L-shaped, straight-line, isosceles triangle, etc.

[0072] The connection device also includes a limit plate 6, and the fixing member 1 includes a slot layer 12 for inserting and removing the limit plate 6. The slot layer 12 can be arranged horizontally, vertically, or obliquely. In some embodiments, the slot layer 12 is arranged horizontally, so the limit plate 6 is also arranged horizontally after being inserted into the slot layer 12. Figure 1 , where horizontal refers to the front-to-back direction and vertical refers to the up-down direction.

[0073] In order to make the multiple joints 8 in a form that matches the filter 3 to be installed after the joints 8 are moved, the outer peripheral side of the joints 8 has at least three limiting parts 9 for radially limiting the joints 8, and at least one limiting part 9 is formed on the limiting plate 6. This means that some of the at least three limiting parts 9 are set on the fixing member 1, and the others are set on the limiting plate 6, or all of them can be set on the limiting plate 6, so the limiting plate 6 plays a very important role in limiting the position of a single joint 8 in each form. The limiting part 9 on the limiting plate 6 can be the limiting plate 6 itself, or a protrusion set on the limiting plate 6 itself, or the inner wall of the limiting groove 61 described below.

[0074] The joint 8 includes a limiting section 84. When the limiting plate 6 is inserted into the slot layer 12, at least three limiting portions 9 can abut against the limiting section 84 to limit the position of the joint 8 in each form on the outer peripheral side of the joint 8. Multiple joints 8 in each form can be docked and sealed with multiple ports 33 of the filter 3. Among them, the limiting section 84 is the height portion where the joint 8 can abut against the limiting portion 9. It is also necessary to explain that at least three limiting portions 9 can radially limit and determine the position of a single joint 8, that is, the opening between any two adjacent limiting portions 9 cannot allow the joint 8 to pass through. For example, the limiting section 84 of the joint 8 is tubular, and at least three limiting portions 9 are distributed on a virtual circle on the outer periphery of the limiting section 84. The opening distance between any two adjacent limiting portions 9 is less than the circular diameter of the tubular limiting section 84.

[0075] It should be emphasized that the limiting portion 9 limits the radial position of the joint 8 in the sense that when the joint 8 is at a certain position in a certain form after moving, the limiting portion 9 can limit the joint 8 from moving in the radial direction (that is, Figure 1 The position limiting portion 9 can be moved at a certain angle in the horizontal direction, that is, in any diameter direction of the circular joint 8). It should also be emphasized that the limiting portion 9 can be directly in contact with the limiting section 84 of the joint 8 for radial limiting, or the limiting portion 9 can have a small gap with the limiting section 84 of the joint 8, so that the limiting section 84 and the limiting portion 9 can be in contact with each other for limiting after the joint 8 is slightly moved, and this small gap will not affect the overall shape of the multiple joints 8, that is, it will not affect the docking seal of the multiple joints 8 and the multiple ports 33, so that the multiple joints 8 are respectively inserted into the multiple ports 33 for sealing connection. As for which of the at least three limiting portions 9 are in direct contact with the limiting section 84 and which are in a small gap with the limiting section 84, there is no specific limitation, as long as at least three limiting portions 9 can limit the single joint 8 to a certain position so that the multiple joints 8 are limited to each form.

[0076] refer to Figure 1 and 2 , 8 and 9, in a preferred embodiment, a limiting groove 61 for the connector 8 to pass through is provided on the limiting plate 6 along the plugging and unplugging direction, and the inner wall of the limiting groove 61 is configured as a limiting portion 9. When the limiting plate 6 is inserted into the slot layer 12, the connector 8 is also inserted into the limiting groove 61, so that the inner wall of the limiting groove 61 can be used as at least one limiting portion 9 to radially limit the connector 8, wherein the limiting groove 61 can be in the shape of a long strip, and the two opposite inner side walls and an inner end wall of the limiting groove 61 can be used as the limiting portion 9 to radially limit the limiting section 84 of the connector 8.

[0077] In another preferred embodiment, not only the limiting portion 9 on the limiting plate 6 plays a radial limiting role on the connector 8, but at least one limiting portion 9 is formed as the inner wall of the moving hole 11, and the inner side wall and the inner end wall of the moving hole 11 can be formed as the limiting portion 9 of the moving hole 11. The limiting portion 9 of the limiting groove 61 and the limiting portion 9 of the moving hole 11 jointly limit the connector 8 in each form. In addition, the limiting portion 9 of the moving hole 11 is arranged relative to the insertion direction of the limiting plate 6, wherein the insertion and extraction direction includes the insertion direction of the limiting plate 6 into the slot layer 12 and the extraction direction of the limiting plate 6 from the slot layer 12. Therefore, the limiting portion 9 of the moving hole 11 radially limits the connector 8 in the insertion direction to prevent the connector 8 from further moving in the insertion direction when it moves to the desired position. The limiting portion 9 of the inner wall of the limiting groove 61 radially limits the connector 8. At this time, the limiting groove 61 and the moving hole 11 are cross-arranged to jointly determine the position of the connector 8.

[0078] In addition, at least three limiting portions 9 are arranged in a vertical position relationship, and one limiting portion 9 is located at a different height position from another limiting portion 9 in the vertical direction. Therefore, the two limiting portions 9 with a height difference can abut against the different height positions of the limiting section 84 of the joint 8, which can prevent the limiting section 84 from tilting relative to the vertical direction to a certain extent, thereby preventing the joint 8 from being excessively tilted and affecting the sealing performance with the port 33.

[0079] In an optional embodiment, there is one limiting plate 6, and multiple groups of limiting grooves 61 are provided on the limiting plate 6, and each group of limiting grooves 61 is used to limit multiple joints 8 in each form. By providing multiple groups of limiting grooves 61 on one limiting plate 6, the number, shape and position of the limiting grooves 61 in each group of limiting grooves 61 can be designed according to the shapes of the multiple joints 8 to be limited in combination with the plug-in direction, and the limiting grooves 61 can be combined with the movable holes 11 to jointly limit the position of the joints 8. The limiting fixation of the multiple joints 8 in various forms that can be combined only relies on one limiting plate 6, which saves the material of the limiting plate 6.

[0080] refer to Figure 2 and 8 , there are multiple limit plates 6 in each form, and the limit grooves 61 on the multiple limit plates 6 are used to jointly limit the multiple joints 8. Multiple joints 8 in each form require multiple limit plates 6 to limit the determined positions. The number, shape and position of the limit grooves 61 on the limit plates 6 can be designed in combination with the plug-in direction and according to the shape of the multiple joints 8 to be limited. It can be that only the limit grooves 61 of the multiple limit plates 6 are used to limit the determined positions of the multiple joints 8 in each form. At this time, at least three limit parts 9 for a single joint 8 are all distributed on the inner walls of the limit grooves 61 of the multiple limit plates 6. It can also be that the limit grooves 61 of the multiple limit plates 6 are combined with the moving holes 11 to jointly limit the determined positions of the multiple joints 8 in each form. At this time, some of the at least three limit parts 9 are distributed on the inner wall of the limit groove 61, and others are distributed on the inner wall of the moving hole 11.

[0081] refer to Figure 6 In some optional embodiments, the plurality of limit plates 6 in each form are defined as being stacked up and down or spaced up and down. The plurality of limit plates 6 can be stacked up and down, or overlapped up and down but with a space between the upper and lower limit plates 6. Although the plurality of limit plates 6 are provided, the arrangement of the plurality of limit plates 6 is varied and adjustable, which is convenient for installation.

[0082] In some optional embodiments, the plurality of joints 8 include a movable joint 81 movably disposed in the movable hole 11 and a positioning joint 82 positioned on the fixing member 1, and the inner wall of the limiting groove 61 can abut against the movable joint 81. When the joint 8 moves, the relative positions of the plurality of joints 8 are changed by the movement of the movable joint 81, and the positioning joint 82 is positioned on the fixing member 1, so the positioning joint 82 itself is limited and fixed on the fixing member 1 and has a certain position, so only the movable joint 81 among the plurality of joints 8 needs to be moved, and it is not necessary to move all the joints 8 to change the relative positions of the plurality of joints 8.

[0083] Furthermore, at least two upper limit grooves 61 are provided on the limit plate 6. When the inner wall of one limit groove 61 abuts against the outer wall of the positioning joint 81, the inner walls of the other limit grooves 61 can abut against the outer wall of the movable joint 81. When the limit plate 6 is inserted into the slot layer 12, until the inner wall of one limit groove 61 abuts against the outer wall of the positioning joint 81, the limit plate 6 is inserted into place in the slot layer 12, and the positioning joint 81 blocks the limit plate 6 from further moving in the insertion direction, preventing the limit plate 6 from being over-inserted, and at this time, the inner walls of the other limit grooves 61 on the limit plate 6 can play a radial limiting role.

[0084] Specifically, the movable hole 11 includes a first movable hole 111 and a second movable hole 112 connected to the first movable hole 111, and the movable joint 81 includes a first joint 811 penetrating the first movable hole 111 and a second joint 812 penetrating the second movable hole 112. The first movable hole 111 is arc-shaped, and the second movable hole 112 is linear. The first joint 811 moves along the shape trajectory of the first movable hole 111, and the second joint 812 moves along the shape trajectory of the second movable hole 112. One of the first joint 811 and the second joint 812 is a liquid inlet joint, and the other is a liquid outlet joint. The positioning joint 81 is an exhaust joint.

[0085] As for the shape of the limiting portion 9, in some embodiments, the inner wall of the limiting groove 61 or the inner wall of the moving hole 11 includes a straight section 71 and an arc section 72, and the straight section and the arc section 72 can be formed as the limiting portion 9. When the limiting portion 9 is an arc section 72, the arc section 72 can abut against the limiting section 84 of the tubular joint 8. When the arc section 72 partially surrounds the limiting section 84 of the joint 8, multiple limiting portions 9 can be provided. If the arc section 72 and the circular limiting section 84 are in contact and fit, the arc section 72 provides at least two limiting portions 9. The number of limiting portions 9 provided mainly depends on the size of the arc section 72. If the arc section 72 is a major arc and the limiting section 84 is radially limited so that the single joint 8 has a certain position, the major arc arc section 72 at this time must provide at least three limiting portions 9 for the single joint 8.

[0086] In a specific embodiment, see Figure 2 and 8 There are two limit plates 6 in each form, and two slot layers 12. The two limit plates 6 in each form can be respectively inserted into the two slot layers 12. The two limit plates 6 in each form can limit the position of the joint 8 more stably. Figure 2 The multiple connectors 8 shown in the figure are in a first straight line shape, with two limit plates 6 arranged opposite to each other and inserted in an opposing manner. At this time, the multiple connectors 8 in a straight line shape can be docked and sealed with the multiple ports 33 of the first filter 31 . Figure 8 The multiple joints 8 shown in the figure are in the second L-shaped form, the two limiting plates 6 are arranged adjacent to each other, the insertion directions of the two limiting plates 6 are perpendicular, and the multiple joints 8 in the L-shape are butt-jointed and sealed with the multiple ports 33 of the second filter 32. It should also be noted that the slot layer 12 has multiple sockets 121, and the two limiting plates 6 can be inserted into the slot layer 12 from different sockets 121, respectively.

[0087] See also Figure 10-Figure 16 , one limiting plate 6 is provided in each form, and the limiting plate 6 is inserted into the slot layer 12 from the front side or the upper side of the fixing member 1, and the limiting portion 9 of one limiting plate 6 in each form and the limiting portion 9 of the moving hole 11 define a plurality of joints 8. When the slot layer 12 is arranged to extend horizontally, the limiting plate 6 can be inserted into the slot layer 12 from the front side of the fixing member 1, and when the slot layer 12 is arranged to extend vertically, the limiting plate 6 can be inserted into the slot layer 12 from the upper side of the fixing member 1.

[0088] In a specific embodiment, Figure 11-12 When the multiple joints 8 are in an L-shape, the limiting plate 6 is inserted into the slot layer 12 from the front side of the fixing member 1. The limiting plate 6 is spoon-shaped. The side wall of the spoon-shaped limiting plate 6 provides multiple limiting portions 9 to radially limit the joints 8. The inner wall of the moving hole 11 provides multiple limiting portions 9 to radially limit the joints 8. Fig.13 When the multiple joints 8 are in a straight line, the limiting plate 6 is inserted into the slot layer 12 from the front side of the fixing member 1, and the limiting groove 61 on the limiting plate 6 passes through the multiple joints 8. The inner wall of the limiting groove 61 provides multiple limiting parts 9 to radially limit the joints 8, and the inner wall of the movable hole 11 provides multiple limiting parts 9 to radially limit the joints 8.

[0089] In a specific embodiment, see Figure 14-16The limiting plate 6 is inserted into the slot layer 12 from the upper side of the fixing member 1. The limiting plate 6 is in a ⊥ shape. The side wall of the limiting plate 6 provides a plurality of limiting portions 9 to radially limit the joint 8. The inner wall of the moving hole 11 provides a plurality of limiting portions 9 to radially limit the joint 8. The slot layers 12 are respectively provided with two, two different slot layers 12 for the limiting plate 6 to be inserted, so as to combine the corresponding plurality of joints 8 into a straight line or an L shape.

[0090] In addition, the opening end of the limiting groove 61 is provided with a guiding inclined surface 62 for guiding the connector 8 into the limiting groove 61. The guiding inclined surface 62 can be an inclined arc surface or an inclined straight surface. When some connectors 8 are not moved into place or move a little too far, during the process of inserting the limiting plate 6 into the slot layer 12, the guiding inclined surface 62 can cooperate with the outer wall (limiting section 84) of the connector 8 to adaptively fine-tune the position of the connector 8, so that the connector 8 can be smoothly inserted into the limiting groove 61.

[0091] In order to avoid random storage of the limit plate 6 after it is pulled out from the slot layer 12, when the limit plate 6 is separated from the slot layer 12, the limit plate 6 is connected to the fixing part 1. Therefore, even if the limit plate 6 is pulled out from the slot layer 12 and the limit groove 61 of the limit plate 6 no longer radially limits the joint 8, the limit plate 6 will not be stored separately in the external area of ​​the connecting device, but will still be connected to the fixing part 1. For example, the limit plate 6 is hung, stuck or rotated on the fixing part 1 to avoid the limit plate 6 being lost when it is needed, saving the staff time in finding the limit plate 6.

[0092] In addition, the connecting device includes a movable member for detachably mounting the filter 3, the movable member 2 being connected below the fixed member 1 and being able to move up and down relative to the fixed member 1. In this embodiment, the movable member 2 is connected to the fixed member 1 through a lifting mechanism 4, the fixed member 1 is connected to an operating member 5 for driving the fixed member 1 to move up and down, and the lifting mechanism 4 may be a scissor lift mechanism, which is a prior art and will not be described in detail herein.

[0093] Specifically, the fixing member 1 includes a base plate 13 connected to the movable member 2 and a mounting plate 14 disposed above the base plate 13. The base plate 13 and the mounting plate 14 are both provided with a moving hole 11, and a slot layer 12 is formed on the mounting plate 14. The mounting plate 14 and the base plate 13 are added together so that the fixing member 1 has a certain height, and the limiting section 84 of the joint 8 can be located between the base plate 13 and the mounting plate 14.

[0094] In order to keep the joint on the fixing member 1 and prevent it from falling down, the fixing member 1 also includes a top plate 15 detachably arranged above the mounting plate 14, the top plate 15 and the mounting plate 14 are spaced apart to form a retaining layer 16, and the joint 8 includes a flange 83 accommodated in the retaining layer 16. The flange 83 is retained in the retaining layer 16 so that the joint 8 is blocked by the flange 83 and does not fall off. When the joint 8 needs to be replaced after being worn, it is only necessary to remove the top plate 14 from the mounting plate 14, and then move the joint 8 upward to take it out, without separating the joint 8 from the port 31 of the filter 3, nor separating the filter 3 from the connecting device. The operation is simple and convenient for the staff to replace the joint 8. In addition, it should be noted that the limit section 84 of the joint 8 can be located between the base plate 13 and the top plate 15, and the height value of the limit section 84 can be set according to the specific insertion situation of the limit plate 6.

[0095] Finally, the connection device further includes a positioning device, and a positioning hole that cooperates with the positioning device is opened on the limiting plate 6. When the limiting plate 6 in the slot layer 12 limits the plurality of connectors 8 to each form, the positioning hole and the positioning device cooperate to limit the movement of the limiting plate 6 along the plugging and unplugging direction. In some embodiments, refer to Fig.11 , the positioning device is a pin, the positioning hole is a through hole on the limiting plate 6, and a hole or groove corresponding to the positioning hole is opened on the fixing member 1. When the limiting plate 6 limits the multiple joints 8 to an L shape, a straight shape or other shapes, the pin is inserted into the positioning hole and the hole on the fixing member 1. Of course, in other embodiments, the positioning device can be a ball plunger fixed in the slot layer 12, and the positioning hole can be a tapered groove. During the process of the limiting plate 6 moving forward along the insertion direction, until the ball head of the positioning hole and the ball plunger contact, the inner wall of the positioning hole squeezes the ball head, so that the ball head and the positioning hole are snap-fitted to achieve the positioning of the limiting plate 6, and in order to ensure the fit between the positioning hole and the ball plunger, the limiting plate 6 can float up and down in the slot layer 12.

[0096] See also Figure 7 and 9 The present invention also provides a filtration system, the filtration system comprising a connection device of any one of the above filters and a filter 3 that can be sealed and connected to the connection device, see Fig.17 and 18 The filter 3 is divided into a first filter 31 and a second filter 32. Of course, the filter 3 can also be other types of filters, such as a plurality of ports 33 of the filter distributed in an isosceles triangle or an equilateral triangle. The filtration system is applied to a fluid system, and the fluid is filtered from the previous process through the filter in the filtration system and enters the next process.
