Description

Technical Field

[0001] This invention relates to the field of bag filter dust collection equipment technology, and in particular to a windproof bag fixing device. Background Technology

[0002] To protect the environment, during the processing of engineering equipment, a windproof bag 1 will be installed at the outlet end of the air duct 2 (refer to...). Figure 7 The purpose of these windproof bags is to collect dust discharged through the ductwork. However, in actual use, due to the flexibility of the windproof bags, their ends become disordered under stress, making it impossible to effectively adjust the angle and position of the bags. This makes them inconvenient to assemble and disassemble, and the bags may cover other equipment during use, affecting their operation. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a windproof bag fixing device, which improves upon the problems of existing technologies that cannot effectively adjust the angle and position of windproof bags, are inconvenient to disassemble and assemble, and may cover other equipment during use, affecting their use.

[0004] According to an embodiment of the present invention, a windproof bag fixing device includes a duct with a windproof bag connected to one end, and further includes: a sleeve fitted on the outside of the duct; a pipe bearing with an inner ring fixed to the outside of one end of the sleeve; a first pipe with one end innerly fixed to the outer ring of the pipe bearing, the end of the duct connected to the windproof bag extending into the first pipe; a second pipe with one end connected to the other end of the first pipe, and the second pipe forming an obtuse angle with respect to the first pipe, and the windproof bag disposed on the first pipe and the second pipe; a fixing unit disposed on the first pipe and abutting against the windproof bag to fix the windproof bag to the duct; and a limiting unit connected to both the sleeve and the first pipe to limit the rotation of the first pipe.

[0005] In summary, the present invention has at least one of the following beneficial technical effects:

[0006] 1. By installing a sleeve on the outside of the duct and a pipe bearing at one end of the sleeve, a first pipe is fixed on the outside of the pipe bearing, and a second pipe forming an obtuse angle with the first pipe is connected to one end of the first pipe. The first and second pipes guide the windproof bag fitted on the duct. The angle of the windproof bag can be changed by rotating the first and second pipes to avoid other equipment. It also allows for easy rotation as needed during the installation and removal of the windproof bag. This improves upon the existing technology, which cannot effectively adjust the angle and position of the windproof bag, is inconvenient to install and remove, and the bag may cover other equipment during use, affecting its use.

[0007] 2. By setting the first pipe as a limiting pipe and a fixing pipe, and setting a fixing unit on the first pipe, the windproof bag can be fixed to the air duct, which facilitates the installation and removal of the windproof bag.

[0008] 3. By setting a limiting unit on the limiting tube, the rotation of the first pipe relative to the sleeve is restricted, and the angle of the second pipe after rotation is kept constant;

[0009] 4. By installing a vibration unit on the second pipe, the windproof bag in the dust collection state is slightly vibrated and slightly impacted to clean the dust adhering to the inner wall of the windproof bag. The dust can be compacted, which increases the loading capacity of the windproof bag 1. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0019] Reference Figure 1 and Figure 2 This invention provides a windproof bag fixing device, including a duct 2, a sleeve 3, a pipe bearing 4, a first pipe 5, a second pipe 6, a fixing unit 7, and a limiting unit 8; the duct 2 is an engineering device used to discharge dusty gas, and the windproof bag 1 is connected to the outlet end of the duct 2 to collect dust.

[0020] In this embodiment of the invention, the sleeve 3 is fitted and fixed to the outside of the outlet end of the air duct 2, and the windproof bag 1 and the sleeve 3 are respectively placed at both ends of the air duct 2. Multiple limiting holes 31 are provided on the outside of the sleeve 3. Figure 1 In the middle, multiple limiting holes 31 are shown as two, and are located on the same straight line. The inner ring of the tube bearing 4 is fixed to the outer side of one end of the sleeve 3, and the tube bearing 4 is located at the end of the sleeve 3 near the windproof bag 1.

[0021] One end of the first pipe 5 is fixed to the outer ring of the pipe bearing 4, so that the first pipe 5 can be rotated, causing the first pipe 5 to rotate relative to the sleeve 3. The other end of the first pipe 5 extends toward the end of the air duct 2 connected to the windproof bag 1, so that part of the structure of the windproof bag 1 is located inside the first pipe 5.

[0022] One end of the second pipe 6 is connected to the other end of the first pipe 5 to guide the closed end of the windproof bag 1. The second pipe 6 is inclined relative to the first pipe 5, forming an obtuse angle, which can be 120°, 130°, 135°, or 150°, etc., so that the second pipe 6 and the first pipe 5 form a bend and guide the windproof bag 1, thereby avoiding other equipment.

[0023] The fixing unit 7 is disposed on the first pipe 5 and simultaneously abuts against the windproof bag 1 to apply pressure to the windproof bag 1, thereby fixing the windproof bag 1 to the air duct 2 and completing the installation of the windproof bag 1. The limiting unit 8 is disposed at the end of the first pipe 5 away from the second pipe 6, and the limiting unit 8 is simultaneously connected to the sleeve 3 and the first pipe 5 to limit the rotation of the first pipe 5.

[0024] During installation, the windproof bag 1 is fitted inside the air duct 2 and fixed to the air duct 2 by the fixing unit 7, allowing the windproof bag 1 to extend along the first pipe 5 and the second pipe 6. Since the second pipe 6 is inclined relative to the first pipe 5, the extension angle of the windproof bag 1 can be indirectly adjusted during installation by rotating the first pipe 5 and fixing it by the limiting unit 8. This allows for angle avoidance of other equipment, improving upon the existing technology's inability to effectively adjust the angle and position of the windproof bag 1, and the problem that the bag may cover other equipment during use, affecting its operation. Furthermore, when it is necessary to remove the windproof bag 1, simply loosening the fixing unit 7 allows the windproof bag 1 to be pulled out directly, improving the inconvenience of installing and removing the windproof bag 1.

[0025] Reference Figure 2 and Figure 3 The first pipe 5 includes a limiting pipe 51, a fixing pipe 52, and a flange assembly 53; one end of the limiting pipe 51 is sleeved on the outside of the sleeve 3 and simultaneously fixed to the outer ring of the pipe bearing 4; multiple insertion holes 511 are provided through the limiting pipe 51, and the multiple insertion holes 511 are connected one by one to the multiple limiting holes 31.

[0026] One end of the fixing tube 52 is connected to the other end of the limiting tube 51; multiple pressure holes 521 are circumferentially opened on the outer side of the fixing tube 52, and the projection of the pressure holes 521 is connected to one end of the windproof bag 1 on the air duct 2; multiple slots 522 are also opened on the outer wall of the fixing tube 52, the multiple slots 522 are evenly distributed circumferentially, and the slots 522 are stepped slots or limiting slots, and are shown as stepped slots in the figure.

[0027] The flange assembly 53 includes a flange and multiple bolts, which are disposed at the end where the limiting tube 51 and the fixing tube 52 are connected to each other to keep them fixed.

[0028] Reference Figures 1 to 3The fixing unit 7 includes an elastic silicone ring 71, multiple pressure blocks 72, and a first driving member 73. The elastic silicone ring 71 is fixed to the outside of the fixing tube 52 and simultaneously covers multiple pressure holes 521. The pressure blocks 72 are fixed to the elastic silicone ring 71, and their two ends extend out from both sides of the elastic silicone ring 71. The multiple pressure blocks 72 are correspondingly arranged in the pressure holes 521, and one end of the pressure block is adapted to and extends into the pressure hole 521.

[0029] The first driving component is mounted on the fixed tube 52 and is used to simultaneously drive multiple pressure blocks 72 to slide into the pressure holes 521 and press the windproof bag 1 into the air duct 2. Specifically, it includes a slider 731, a frustum ring 732, and a driving component 733. The slider 731 is adapted to and slidably connected to the slot 522 along the length of the fixed tube 52; the frustum ring 732 is fixed to multiple sliders 731 at the same time, and the frustum ring 732 opens towards the pressure block 72, with its inner surface being inclined, so that during the upward sliding of the frustum ring 732, the inclined surface of the frustum ring 732 contacts the pressure block 72 and applies pressure towards the pressure block 72.

[0030] A driving component 733 is disposed on the fixed tube 52 for driving the slider 731 to slide. It includes a threaded tube 7331, a threaded sleeve 7332, a wrench 7333, a drive bearing 7334, and a fixing bracket 7335. The threaded tube 7331 is sleeved on the fixed tube 52, and one end of the threaded tube 7331 is fixed to the slider 731. The threaded sleeve 7332 is threadedly connected to the threaded tube 7331. Multiple wrenches 7333 are provided and fixed to one end of the threaded sleeve 7332. The inner ring of the drive bearing 7334 is fixed to the other end of the threaded sleeve 7332 and is located away from the frustum-shaped ring sleeve 732 relative to the wrench 7333. The fixing bracket 7335 is U-shaped, with one end fixed to the outer ring of the drive bearing 7334, and the other end bent and fixed to the fixed tube 52 to prevent the threaded sleeve 7332 from moving up and down.

[0031] When it is necessary to remove the windproof bag 1, force is first applied to the wrench 7333, causing the threaded sleeve 7332 to rotate. Under the constraint of the fixing bracket 7335, the threaded sleeve 7332 can only rotate. At the same time, under the constraint of the slot 522 on the slider 731, the threaded tube 7331 connected to the threaded sleeve 7332 can only slide. Consequently, the downward sliding frustum ring 732 slides downward and disengages from the pressure block 72. Under the elastic action of the elastic silicone ring 71, the elastic silicone ring 71 rebounds and causes the pressure block 72 to slide outward, disengaging the pressure block 72 from the windproof bag 1. This allows the windproof bag 1 to be easily removed, improving the problem of inconvenient disassembly and assembly of the windproof bag 1 in the prior art. Of course, the disassembly and assembly of the windproof bag 1 can also be achieved by first removing the fixing unit 7 from the windproof bag 1 and removing the fixing tube 52.

[0032] When installing the windproof bag 1, it can be pre-fixed using conventional methods such as ropes and glue, and then finally fixed using the fixing unit 7.

[0033] Among them, a pressure groove 21 is formed on the side of the air duct 2 opposite to the pressure block 72, so that the windproof bag 1 is pressed into the pressure groove 21 under the pressure of the pressure block 72, thereby enhancing the installation effect.

[0034] Reference Figure 1 , Figure 4 as well as Figure 5 The limiting unit 8 includes an annular shell 81, a sliding plate 82, a T-shaped rod 83, and a second driving member 84; the annular shell 81 is fixed to the outside of the limiting tube 51 and opens towards the insertion hole 511. The sliding plate 82 is fixed inside the insertion hole 511, and a sliding hole is provided through the sliding plate 82.

[0035] One end of the T-shaped rod 83 is adapted to and slidably connected to the sliding hole of the slide plate 82, and this end extends into the annular shell 81, while the other end (T-shaped end) is adapted to and extends into the limiting hole 31.

[0036] The second driving component 84 is used to drive the T-shaped end of the T-shaped rod 83 into the limiting hole 31. It includes a pressure plate 841, a first spring 842, and an L-shaped rod 843. The pressure plate 841 is fixed to one end of the T-shaped rod 83 that extends into the annular shell 81. The first spring 842 is sleeved on the T-shaped rod 83, and its two ends abut against the sliding plate 82 and the pressure plate 841 respectively, so that under the action of the elastic force of the first spring 842, the T-shaped end of the T-shaped rod 83 extends into the limiting hole 31, preventing the limiting tube 51 from rotating relative to the sleeve 3.

[0037] One end of the L-shaped rod 843 extends into the annular shell 81 through a pre-drilled sliding hole and is fixed to the pressure plate 841.

[0038] When it is necessary to rotate the first pipe 5, force is applied to the L-shaped rod 843 to overcome the elastic force of the first spring 842, so that the T-shaped end of the T-shaped rod 83 can be disengaged from the limiting hole 31.

[0039] Reference Figure 5 In other embodiments, two sets of limiting units 8 are arranged facing each other on the limiting tube 51 along the radial direction of the limiting tube 51 to enhance the limiting effect; the two L-shaped rods 843 extend out of the annular shell 81 and bend towards each other, and a baffle 844 is fixed at the opposite end to apply force to the two baffles 844 at the same time, so that the two L-shaped rods 843 move away from each other and drive the two T-shaped rods 83 to disengage from the two limiting holes 31 at the same time.

[0040] Reference Figure 1 and Figure 6 A groove 61 is provided through the second pipe 6, and the groove of the groove 61 extends along the length of the second pipe 6.

[0041] The vibration unit 9 includes an arc-shaped protrusion 91, a ring plate 92, a cross rod 93, a second spring 94, an arc-shaped plate 95, and a third driving component 96. The arc-shaped protrusion 91 is disposed on the inner wall of the second pipe 6 and is arranged at intervals along the length of the second pipe 6; the ring plate 92 is disposed inside the second pipe 6 and is arranged at intervals along the length of the second pipe 6, and multiple stepped holes 921 are opened through the ring plate 92 circumferentially.

[0042] The cross rod 93 is provided in multiple stepped holes 921, and its opposite ends are slidably connected to the hole wall of the stepped hole 921. The other two ends extend along the hole direction of the stepped hole 921, and both ends along the hole direction of the stepped hole 921 extend out of the stepped hole 921.

[0043] Multiple second springs 94 are provided and evenly distributed within multiple stepped holes 921. The two ends of each second spring 94 are fixed to the wall of the stepped hole 921, and the cross rod 93 is slidably connected to one end of the wall of the stepped hole 921, so that under the elastic force of the second spring 94, the cross rod 93 abuts against the inner wall of the second pipe 6. An arc-shaped plate 95 is disposed within the ring plate 92 and fixed to the cross rod 93. A windproof cloth bag 1 is disposed inside the arc-shaped plate 95.

[0044] The third driving component 96 is disposed on the second pipe 6 so that multiple ring plates 92 slide along the length direction of the second pipe 6. The third driving component 96 includes a fixed plate 961, a push plate 962, a base plate 963, a protruding rod 964, a cam 965, a drive motor 966, and a third spring 967. Multiple fixed plates 961 are disposed on the inner side of the second pipe 6, and the fixed plates 961 are simultaneously fixed to multiple ring plates 92.

[0045] One end of the push plate 962 is fixed to the fixed plate 961, and the other end extends out of the slide groove 61 and is slidably connected to the slide groove 61 along the length of the second pipe 6; the base plate 963 is fixed to the outside of the second pipe 6; one end of the protruding rod 964 is fixed to the push plate 962, and the other end is slidably connected to the base plate 963.

[0046] Cam 965 abuts against one end of protruding rod 964, which is fixed to push plate 962. Drive motor 966 is fixed to second pipe 6 via bracket, and its output end is fixed to cam 965 so that drive motor 966 can drive cam 965 to rotate. Third spring 967 is sleeved on protruding rod 964, and its two ends abut against push plate 962 and base plate 963 respectively.

[0047] During the dust collection process through the windproof bag 1, the bag 1 inflates under pressure. At this time, the cam 965 rotates via the drive motor 966, causing the convex rod 964, push plate 962, and fixed plate 961 to move together along the length of the second pipe 6, simultaneously moving multiple ring plates 92. During this process, under the action of the second spring 94, the cross rod 93 gradually contacts multiple arc-shaped protrusions 91, causing the arc-shaped plate 95 to move and slightly impact the windproof bag 1, cleaning the dust adhering to the inner wall of the bag 1. This compaction of the dust increases the loading capacity of the windproof bag 1. Simultaneously, under the action of the cam 965 and the third spring 967, the arc-shaped plate 95 reciprocates along the length of the second pipe 6.

[0048] Along the length of the second pipe 6, both sides of the cross rod 93 that abut against the inner wall of the second pipe 6 are chamfered to form an arc surface, so as to ensure smooth contact between the cross rod 93 and the arc-shaped protrusion 91.

[0049] Multiple combing blocks 951 are formed on the inner side of the arc plate 95 so that during the process of impacting the windproof bag 1 by the arc plate 95, the combing blocks 951 slide and comb the surface of the windproof bag 1 to prevent dust from adhering to the inside of the windproof bag 1.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
