Description

Technical Field

[0001] This utility model relates to the field of connection structure technology, specifically to a connection structure for a metal filter cartridge. Background Technology

[0002] Open the top end cover of the dust collector and install the filter cartridge from top to bottom. A common method involves creating through holes in the mounting plate inside the dust collector, with multiple bolts welded around the circumference of these holes. The upper end cover of the filter cartridge is flanged, with a sealing ring bonded to one side of the flange. Multiple evenly distributed circular holes are located around the flange, through which the upper bolts pass. The two are aligned one-to-one, and then tightened with nuts. Because the filter cartridge is installed from top to bottom, the operator's working space is relatively narrow during installation, which can be inconvenient in situations where the internal space of the dust collector is limited. Utility Model Content

[0003] The main purpose of this utility model is to provide a connection structure for metal filter cartridges to solve the problem that in the prior art, when filter cartridges are installed from top to bottom of the dust collector, the operating space for operators is relatively narrow, which brings inconvenience to the installation work.

[0004] To achieve the above objectives, this utility model provides a connection structure for a metal filter cartridge, which is installed on the mounting plate of a dust collector. The mounting plate has mounting holes and includes the filter cartridge.

[0005] The top of the filter cartridge is coaxially detachable and connected to a branch pipe, which passes through the mounting hole and is circumferentially arranged with multiple supporting components.

[0006] The erection components include a support frame, a U-shaped rod, and a horizontal rod, with limiting grooves on the support frame;

[0007] The support is fixedly connected to the branch pipe, and a horizontal rod perpendicular to the axis of the branch pipe is fixed on the support.

[0008] A spring is fitted onto the horizontal bar, and U-shaped rods are fixed at both ends of the spring, with the sealed section abutting against the mounting plate;

[0009] A limiting rod is fixed on the spring, and the limiting rod is inserted into the limiting groove;

[0010] With the spring in a free state, the U-shaped rod abuts against the branch pipe.

[0011] Preferably, the support includes an arc-shaped plate, a support rod, and two parallel horizontal plates. One end of the two horizontal plates is fixedly connected to the outer wall of the arc-shaped plate, and the inner wall of the arc-shaped plate is fitted and fixedly connected to the annular wall of the branch pipe.

[0012] Both ends of the horizontal bar and both ends of the abutment bar are fixedly mounted on the two horizontal plates.

[0013] The space between the abutment rod and the arc plate forms a limiting groove;

[0014] The end of the limit rod away from the spring abuts against the arc-shaped plate or the abutment rod.

[0015] Preferably, the limiting rod, spring, and U-shaped rod are integrated into one structure.

[0016] Preferably, the filter cartridge is composed of multiple sections of cylindrical body coaxially spliced ​​together;

[0017] The cylinder body includes two clips, a filter element, and a filter screen;

[0018] Each card consists of an inner tube and an outer tube;

[0019] A first flange is coaxially fixed on the outer wall of the inner tube, and a first internal thread is opened on the circumference of the inner wall, and a first external thread is opened on the circumference of the outer ring wall of the inner tube.

[0020] A second flange is coaxially fixed to the outer wall of the outer pipe;

[0021] The inner tube is coaxially inserted inside the outer tube, and the first flange and the second flange are coaxially abutting against each other and fixedly connected by fasteners.

[0022] The space between the inner and outer tubes forms an annular groove;

[0023] The filter element and filter screen are inserted into two annular grooves and are coaxially located around the filter screen.

[0024] Both ends of the filter screen have a second internal thread on their outer walls, and the first external thread is screwed into the second internal thread.

[0025] Preferably, a third external thread is provided on the outer ring wall circumference of the end of the branch pipe away from the erection component, and the third external thread is screwed into the first internal thread of the cylinder located at the top.

[0026] Preferably, it also includes a plug, the outer ring wall of which has a fourth external thread, which is screwed into the first internal thread of the cylinder located at the bottom.

[0027] Preferably, the fasteners include multiple bolts and multiple nuts, with the bolts passing through the first flange and the second flange and being screwed to the nuts, or the bolts passing through the first flange, the second flange, an adjacent first flange, and an adjacent second flange and being screwed to the nuts.

[0028] Preferably, the filter element is made of polypropylene fiber.

[0029] The beneficial effects of the above scheme are:

[0030] Initially, the filter cartridge and branch pipe are relatively separated. Multiple U-shaped rods on the mounting components abut against the branch pipe, with one end of the branch pipe passing through the mounting hole. This allows the sealed ends of the multiple U-shaped rods to abut against the mounting plate, and each U-shaped rod is angled. Furthermore, one end of the branch pipe is coaxially connected to the top of the filter cartridge, and the mounting plate is abutting the top of the filter cartridge. Multiple springs are in a relatively stretched state, causing the U-shaped rods to tend towards the branch pipe, thus securely installing the filter cartridge at the mounting hole of the dust collector. This separate design of the branch pipe and filter cartridge, using the self-adaptive abutment of the U-shaped rods and mounting plate, achieves pre-positioning of the filter cartridge assembly. When the springs are in a free state, the U-shaped rods naturally retract to form a pre-clamping state. During installation, only vertical pushing is needed to complete the initial alignment, improving efficiency compared to traditional bolt fastening methods. Attached Figure Description

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0044] like Figures 1-5 As shown, this embodiment provides a connection structure for a metal filter cartridge, installed on a mounting plate 1 of a dust collector (not shown). The mounting plate 1 divides the dust collector into a dirty gas chamber (not shown) and a clean gas chamber (not shown). Mounting holes 11 are provided on the mounting plate 1. The connection structure of the metal filter cartridge includes a filter cartridge 2, which is located in the dirty gas chamber. The top of the filter cartridge 2 is coaxially and detachably connected to a branch pipe 3. Multiple supporting components 4 are arranged circumferentially through the mounting holes 11. Figure 2 As shown, the erection component 4 includes a support 41, a U-shaped rod 42, and a horizontal rod 43. The support 41 has a limiting groove 40. The support 41 includes an arc-shaped plate 410, abutment rod 46, and two parallel horizontal plates 411. One end of the two horizontal plates 411 is fixedly connected to the outer wall of the arc-shaped plate 410, and the inner wall of the arc-shaped plate 410 is fitted and fixedly connected to the annular wall of the branch pipe 3. Both ends of the horizontal rod 43 and both ends of the abutment rod 46 are fixedly mounted on the two horizontal plates 411, wherein the space between the abutment rod 46 and the arc-shaped plate 410 forms a limiting groove 40. The end of the limiting rod 45 away from the spring 44 abuts against the arc-shaped plate 410 or the abutment rod 46. The support 41 is fixedly connected to the branch pipe 3, and the horizontal rod 43, perpendicular to the axis of the branch pipe 3, is fixedly mounted on the support 41. A spring 44 is fitted onto the horizontal rod 43. U-shaped rods 42 are fixed to both ends of the spring 44, and the sealed section of the spring 44 abuts against the mounting plate 1. A limiting rod 45 is fixed to the spring 44 and inserted into a limiting groove 40. When the spring 44 is in a free state, the U-shaped rod 42 abuts against the branch pipe 3. The limiting rod 45, spring 44, and U-shaped rod 42 are a single integrated structure. The limiting groove 40 formed by the abutment rod 46 and the arc-shaped plate 410 constrains the movement trajectory of the spring 44.

[0045] In the initial state, the filter cartridge 2 and the branch pipe 3 are relatively separated. Multiple U-shaped rods 42 on the mounting components 4 abut against the branch pipe 3. One end of the branch pipe 3 passes through the mounting hole 11, causing the sealed ends of the multiple U-shaped rods 42 to abut against the mounting plate 1. Each U-shaped rod 42 is inclined. Furthermore, one end of the branch pipe 3 is coaxially connected to the top of the filter cartridge 2. The mounting plate 1 is abutted against the top of the filter cartridge 2. Multiple springs 44 are in a relatively stretched state, causing the U-shaped rods 42 to tend to move towards the branch pipe 3. This securely mounts the filter cartridge 2 at the mounting hole 11 of the dust collector. The separate design of the branch pipe 3 and the filter cartridge 2, along with the self-adaptive abutment of the U-shaped rods 42 and the mounting plate 1, achieves pre-positioning of the filter cartridge 2 assembly. When the springs 44 are in a free state, the U-shaped rods 42 naturally retract to form a pre-clamping state. During installation, only vertical pushing is needed to complete the initial alignment, improving efficiency compared to traditional bolt fastening methods.

[0046] like Figure 3 As shown, the filter cartridge 2 is coaxially assembled from multiple cylindrical sections 20. Each cylindrical section 20 includes two retaining clips 21, a filter element 22, and a filter screen 23. The filter element 22 is made of polypropylene fiber. Figure 4 As shown, each fitting 21 includes an inner tube 210 and an outer tube 211. A first flange 2101 is coaxially fixed to the outer wall of the inner tube 210, and a first internal thread (not shown) is formed on the circumference of the inner wall of the inner tube 210. A first external thread 2103 is formed on the circumference of the outer ring wall of the inner tube 210. A second flange 2110 is coaxially fixed to the outer wall of the outer tube 211. The inner tube 210 is coaxially inserted into the outer tube 211, and the first flange 2101 and the second flange 2110 are coaxially abutted against each other and fixedly connected by fasteners 212. The space between the inner tube 210 and the outer tube 211 forms an annular groove 213. The filter element 22 and the filter screen 23 are inserted into the two annular grooves 213, and the filter element 22 is coaxially located around the filter screen 23. Both ends of the filter screen 23 have a second internal thread 230 on their outer walls, and the first external thread 2103 is screwed into the second internal thread 230. A third external thread 31 is formed on the outer ring wall of the end of the branch pipe 3 away from the erection component 4. The third external thread 31 is screwed into the first internal thread of the top cylinder 20. By screwing the third external thread 31 into the first internal thread of the top cylinder 20, the branch pipe 3 and the cylinder 20 can be quickly assembled.

[0047] The connection structure of the metal filter cartridge 2 also includes a plug 5, the outer ring wall of which has a fourth external thread (not shown), which is screwed into the first internal thread of the cylinder 20 located at the bottom.

[0048] Fastener 212 includes multiple bolts 2120 and multiple nuts 2121. Bolts 2120 pass through a first flange 2101 and a second flange 2110 and are screwed to nuts 2121, or bolts 2120 pass through a first flange 2101, a second flange 2110, an adjacent first flange 2101, and an adjacent second flange 2110 and are screwed to nuts 2121. Fastener 212 completes the assembly of multiple cylinders 20 or the connection of adjacent cylinders.

[0049] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
