Description

Technical Field

[0001] The present invention relates to the technical field of filter bag frames, and more particularly to a frame for filter bags which is easy to assemble. Background Art

[0002] In industrial dust removal systems, the filter bag frame is the core component that supports the filter bag. Its fixing performance is directly related to the operation effect of the entire dust removal system. However, the filter bag frames commonly used in the market have technical defects, which are mainly reflected in the design of their fixing mechanism. Traditional filter bag frames usually adopt a simple mechanical fixing method. This fixing method is not only cumbersome to install, but also prone to loosening during long-term operation, resulting in a gap between the filter bag and the frame, affecting the dust removal effect.

[0003] More importantly, during the operation of the dust removal system, especially during filtering and pulse dust removal operations, the existing filter bag frame design fails to fully utilize the airflow kinetic energy generated during system operation. This neglect of wind resources makes it impossible for the frame to obtain additional fixed support force through airflow pressure, which not only reduces the operating stability of the system, but also seriously affects the overall performance and service life of the dust removal system. Summary of the invention

[0012] Preferably, a plurality of stop sleeves are installed at equal intervals on both sides of the support rod, and each stop sleeve is threadedly connected with a support bolt. When pulse dust removal is performed, the flip plate is attached to the support bolt.

At the same time, the threaded connection design also facilitates the adjustment of the support position.

[0013] Preferably, a cone head is installed on the end of each support bolt away from the stop sleeve, and a fixing spring is connected to the cone head. Multiple fixing springs are sleeved on the support bolt, and the fixing springs are in contact with the stop sleeve.

[0014] Preferably, the connecting mechanism also includes an insertion rod fixedly mounted on the upper ends of the plurality of vertical sleeves, the insertion rod is connected in the outer sleeve, and the top rod is slidably connected in the insertion rod. This design provides a stable supporting structure through the connection between the insertion rod and the outer sleeve, and the sliding connection of the top rod increases the flexibility of the structure, so that the overall device can adapt to different working conditions.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a frame for filter bags that is easy to assemble, having the following features:

[0021] Beneficial effects:

[0022] This application innovatively adopts the design concept of multiple fixations and adaptive pressurization. Through the combined structure of the vertical sleeve and the bidirectional sleeve, stable support of the skeleton is achieved. The cooperation of the bidirectional rod, the resistance sleeve and the support rod not only provides basic structural support, but also can automatically adjust the support strength according to the operating conditions. The design of the telescopic rod and the follow-up ball, combined with the guiding effect of the semicircular groove, realizes the automatic reinforcement function of the skeleton when it is under stress. The combination of the flip plate and the return spring set on the internal rod, the cooperation of the stop sleeve and the support bolt, and the design of the cone head and the fixing spring ensure the reliable fixation of the skeleton under different working conditions.

[0023] The skeleton adopts an innovative two-way locking mechanism. The cooperation between the top rod and the receiving rod, through the combination of the side plate and the limit sleeve, realizes stable axial positioning. The design of the external sleeve and the lateral groove, combined with the positioning function of the insertion rod, ensures the precise installation of the skeleton. The combination of the push sleeve and the rotating disk, the design of the internal sleeve and the annular plate, combined with the sliding mechanism of the clamping frame and the internal ball, is not only easy to install, but also can automatically strengthen the fixing effect during operation, thereby improving the reliability of the skeleton and the convenience of maintenance.

[0024] The present application realizes the function of wind pressure adaptive reinforcement. During normal dust removal, the pressure generated by the filter bag will be transmitted to the two-way rod through the resistance sleeve, thereby driving the follower ball to generate an upward thrust to enhance the fixing effect. During pulse dust removal, the design of the flip plate can utilize the pressure generated by the reverse airflow to further enhance the stability of the frame through the expansion effect of the two-way rod. This adaptive design not only improves the stability of the frame, but also improves the safety of dust removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] See also Figures 1 to 11A skeleton for filter bags that is easy to assemble, comprising an outer ring 11 installed on an external device and a skeleton body 12 coaxially arranged with the outer ring 11, a pressurizing mechanism, comprising a plurality of vertical sleeves 21 installed on the skeleton body 12, each vertical sleeve 21 is respectively installed with a plurality of bidirectional sleeves 22, each bidirectional sleeve 22 is respectively connected with a bidirectional rod 23 in a limited sliding manner, a resistance sleeve 24 and a support rod 25 are respectively installed on both sides of every two bidirectional rods 23, the support rod 25 and the resistance sleeve 24 form a certain angle, a telescopic rod 26 is respectively coaxially arranged in each vertical sleeve 21, each telescopic rod 26 is respectively installed with a follower ball 27 of the same number as the bidirectional rod 23, each bidirectional rod 23 is respectively provided with a semicircular groove 28, and the follower ball 27 is fitted and connected in the semicircular groove 28, and the pressurizing mechanism also includes an inner rod 2 installed on the two bidirectional rods 23 9. The inner rod 29 and the support rod 25 have the same angle as the abutment sleeve 24. Two follower tubes 210 are symmetrically mounted on the inner rod 29 for rotation. A flip plate 211 is mounted on each follower tube 210, and a return spring 212 is coaxially mounted on each follower tube 210. The return springs 212 at both ends are respectively connected to the two ends of the inner rod 29. A plurality of stop sleeves 213 are equidistantly mounted on both sides of the support rod 25, and a support bolt 214 is threadedly connected to each stop sleeve 213. When pulse dust removal is performed, the flip plate 211 fits onto the support bolt 214, and a cone head 215 is mounted on the end of each support bolt 214 away from the stop sleeve 213. A fixing spring 216 is connected to the cone head 215. A plurality of fixing springs 216 are sleeved on the support bolt 214, and the fixing spring 216 abuts against the stop sleeve 213.

[0041] When the frame body 12 needs to be fixed, the diameter between the multiple clamping frames 314 is larger than the diameter of the insertion rod 37, and then the multiple insertion rods 37 can be inserted into the outer sleeve 35 respectively, and the insertion rods 37 are abutted against the outer sleeve 35. At this time, the multiple clamping frames 314 are retracted toward the axis. Figure 8 , and then the clamping frame 314 is inserted into the annular groove 318. Since the insertion rod 37 is in contact with the outer sleeve 35 at this time, and the clamping frame 314 is also fitted on the bracket 317, the insertion rod 37 and the outer sleeve 35 are in a fixed state at this time. When the top rod 31 moves upward, the top rod 31 will press on the receiving rod 32, and then drive the limiting sleeve 34 and the pushing sleeve 38 to move upward. Under the action of the positioning groove 311 and the positioning strip 310, the pushing sleeve 38 and the rotating disk 39 are in an axial angle positioning state. Since the side plate 33 is stuck in the lateral groove 36, the inner sleeve 312 is in a fixed state. Please refer to Figure 7, and will drive the inner sleeve 312 to have an upward pushing force, and then the inner sleeve 312 will drive the annular plate 313 and the clamping frame 314 to have an upward moving force. Since the annular plate 313 is connected to the clamping frame 314, the clamping frame 314 also has an upward force. The clamping frame 314 is clamped in the annular groove 318, and thus it will further drive the insertion rod 37 to push against the outer sleeve 35 to ensure the stability of the fixation, and also ensure that the relative position of the clamping frame 314 will not move.

[0042] When performing normal dust removal after installing the filter bag, refer to Figure 4 Since the filter bag is sleeved on the multiple resistance sleeves 24, the multiple resistance sleeves 24 will be compressed toward the axis. At this time, the semicircular groove 28 on the two-way rod 23 will press on the follower ball 27, and then the follower ball 27 will move upward, and then the top rod 31 will have a continuous force to press on the receiving rod 32 to further ensure the stability of the fixation. Since the multiple resistance sleeves 24 are contracted respectively, it is ensured that the multiple top rods 31 will have a continuous upward force, ensuring that the filter bag can be further improved by wind pressure when performing normal dust removal. Please refer to Figure 3 As the outside wind blows into the filter bag, the greater the wind force, the greater the fixing force. The two flip plates 211 on the internal rod 29 are not restricted in this direction, so the flip plates 211 rotate toward the axis to reach the position of minimum resistance, minimizing the impact on dust removal.

[0043] Before pulse dust removal, please stop the machine first. Figure 3 After shutdown, under the action of the return spring 212, the multiple flip plates 211 are respectively in contact with the support bolts 214, so that the multiple flip plates 211 are in the position with the maximum wind resistance, and then during reverse pulse dust removal, the flip plates 211 will drive the two-way rod 23 to expand outward under the action of wind pressure. Due to the inclined setting of the flip plates 211, the two-way rod 23 will have a force to expand outward, and then the follower ball 27 will still push upward, and will still drive the top rod 31 to move upward, thereby improving the stability of the fixation. Therefore, no matter in which direction the skeleton body 12 is subjected to force, the fixation effect will be enhanced, thereby ensuring stability during use.

[0044] See also Figures 7 to 11, a connecting mechanism includes a top rod 31 installed on the telescopic rod 26, the upper end of the top rod 31 is fitted with a receiving rod 32, a plurality of side plates 33 are installed on the side wall of the receiving rod 32 at equal intervals, and a limiting sleeve 34 is coaxially installed on the outer side of the side plate 33, a plurality of external sleeves 35 are installed on the external ring 11, and the outer wall of the external sleeve 35 is provided with lateral grooves 36 of the same number as the side plates 33, and the side plates 33 are slidably connected in the lateral grooves 36, and the receiving rod 32 is slidably connected in the external sleeve 35, and the connecting mechanism also includes an insertion rod 37 fixedly installed on the upper ends of the plurality of vertical sleeves 21, the insertion rod 37 is connected in the external sleeve 35, and the top rod 31 is slidably connected in the insertion rod 37, a push sleeve 38 is coaxially installed at the lower end of the limiting sleeve 34, a rotating disk 39 is fitted on the push sleeve 38, and the rotating disk 39 is rotatably connected to the limiting sleeve On the positioning sleeve 34, a plurality of positioning strips 310 are installed on the rotating disk 39, and a plurality of positioning grooves 311 are opened on the rotating disk 39. The number of positioning grooves 311 is an integer multiple of the number of positioning strips 310, and the positioning strips 310 are clamped in the positioning grooves 311. An inner sleeve 312 is installed at the lower end of the rotating disk 39. An annular plate 313 is rotatably clamped in the inner sleeve 312. A clamping frame 314 is installed on the annular plate 313. Two inner balls 315 are symmetrically installed in the clamping frame 314. A plurality of expansion grooves 316 are respectively opened on both sides of the inner sleeve 312. The inner balls 315 are slidably connected in the expansion grooves 316. A plurality of brackets 317 are opened on the outer wall of the outer sleeve 35. The clamping frame 314 is slidably connected in the brackets 317. An annular groove 318 is opened on the side wall of the insertion rod 37, and the clamping frame 314 is inserted into the annular groove 318.

[0045] When multiple card brackets 314 need to be expanded outward during installation, please refer to Figure 7 By rotating the inner sleeve 312, the expansion groove 316 will rotate accordingly. Since the internal ball 315 is slidably connected in the expansion groove 316, it will drive multiple clamping frames 314 to expand outward, making it convenient to fix. When subjected to wind pressure, the push sleeve 38 and the inner sleeve 312 will be subjected to an upward force, and then will drive multiple clamping frames 314 to move upward accordingly. Since the clamping frame 314 is stuck in the annular groove 318, it will exert an upward thrust on the insertion rod 37, thereby enhancing its fixing effect, thereby ensuring the stability of the fixation. When there is no wind pressure, the top rod 31 does not contact the receiving rod 32, thereby ensuring the convenience of rotation. Therefore, the greater the wind force, the greater the fixing force. When there is no wind pressure, there is no additional fixing force, thereby ensuring the convenience of use.

[0046] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
