Description

Technical Field

[0001] The present invention relates to the technical field of filter bags, and more particularly to a smoke filter bag. Background Art

[0002] In modern industrial production processes, the continuous and stable operation of smoke filtration systems is crucial to meeting production efficiency and environmental protection requirements. Traditional smoke filter bags often face a thorny problem in practical applications: Under certain special production conditions, such as continuous production tasks or emergency order processing, the filter bag system is required to perform long-term uninterrupted filtering operations. In this case, the requirement of regular shutdown for dust removal maintenance according to conventional operating procedures is difficult to meet production needs, because any shutdown processing may lead to interruption of the production line, resulting in a significant decrease in production efficiency.

[0003] However, if dust removal is not carried out in time, a large amount of dust particles will gradually accumulate on the outer wall of the filter bag. These accumulated dust will form a dense dust layer on the surface of the filter bag, significantly increasing the resistance of the filter medium, causing a sharp drop in filtration efficiency. This will not only reduce the filtration performance of the equipment, but also increase the energy consumption of the system, and may even cause premature damage to the filter bag. This technical dilemma seriously affects the continuity and stability of production, and will ultimately have a significant negative impact on the overall production progress. Summary of the invention

[0009] The pushing mechanism comprises a plurality of supporting springs which are installed at equal intervals on the outside of the frame, and a laminating frame is installed on every four supporting springs respectively, and a sliding sleeve is vertically slidably connected to the laminating frame.

[0010] Preferably, a plurality of the laminating frames are laminatingly connected with a filter bag body, the filter bag body is fixedly mounted on the fixing ring, and two impact heads are respectively mounted on a plurality of the folding plates, and the two impact heads are respectively mounted on the upper and lower sides of the folding plates. In this design, the laminating frame provides a stable supporting structure and power transmission for the filter bag body, the fixing ring ensures the overall fixation, and the impact heads symmetrically arranged above and below can clean different positions of the filter bag body at the same time, thereby improving the dust removal efficiency, and forming an efficient basic support and dust removal structure as a whole.

[0011] Preferably, the dust removal mechanism also includes a follower sleeve rotatably connected to the internal rod, and the one-way wheel is limitedly fitted in the follower sleeve. This design achieves the transmission and control of motion through the cooperation of the follower sleeve and the one-way wheel. The rotational connection of the follower sleeve ensures the smoothness of the motion, and the limited fit prevents deviation during the motion, thereby forming a stable and reliable transmission mechanism.

[0012] Preferably, a plurality of separation sleeves are installed at equal intervals on each of the internal rods, and every two of the follower sleeves symmetrically arranged up and down are respectively fitted on the separation sleeves. This design ensures the accuracy and smoothness of the movement of the follower sleeves through the equal-interval arrangement and symmetrical setting of the separation sleeves. The limiting effect of the separation sleeves effectively prevents the movement of the moving parts, thereby constructing a precise position control system.

[0013] Preferably, a limiting groove is respectively provided in each of the follower sleeves, and a follower rod is respectively connected in a limiting sliding manner in each of the limiting grooves, and an intermediate groove is respectively provided in each of the follower rods. This design achieves precise guiding of the movement through the sliding cooperation of the limiting groove and the follower rod. The setting of the intermediate groove provides installation space for subsequent mechanisms, thereby forming a precise motion guiding system as a whole.

[0014] Preferably, a plurality of one-way sleeves are rotatably installed in the middle groove, a one-way block is installed on each of the one-way sleeves, a plurality of one-way grooves are evenly spaced along the axis on the side wall of the one-way wheel, and the one-way blocks are clamped in the one-way grooves.

[0018] Preferably, the dust removal mechanism and the pushing mechanism are arranged in no less than six groups along the skeleton. This design ensures the comprehensiveness and uniformity of the dust removal effect through the uniform arrangement of multiple groups of mechanisms, improves the overall work efficiency, and constructs a comprehensive and efficient dust removal system.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a smoke filter bag, which has the following beneficial effects:

[0021] First of all, in the design of the dust removal mechanism, a convenient dust removal system is adopted. Through the ingenious cooperation of the internal rod and the rotating sleeve, combined with the energy storage mechanism of the bidirectional spring, an impact dust removal device is formed. When the filter pressure is detected to be reduced, the dust removal process can be triggered by increasing the air inlet pressure without stopping the machine, which effectively improves the continuous operation capacity of the equipment. The symmetrical design of the impact head and the synchronous impact mechanism ensure the uniformity and reliability of the dust removal effect.

[0022] Secondly, in terms of power transmission, the effective accumulation and release of energy is achieved through the coordinated work of the one-way wheel, the follower sleeve and the one-way block. This design not only ensures the control of the impact force, but also avoids reverse interference through the one-way mechanism, making the entire dust removal process more stable and reliable. The double-way spring design provides a reliable energy storage and release mechanism, ensuring the effect of impact dust removal.

[0023] Finally, in terms of the driving mechanism, a power transmission mechanism is constructed through the cooperation of the support spring and the fitting frame. When the wind pressure changes, the system can automatically adjust the position of the internal components to ensure that the dust removal device is always in the best working state. The uniform arrangement of multiple groups of dust removal mechanisms ensures that the entire filter bag surface can be effectively cleaned. This multiple protection mechanism significantly improves the service life and filtration efficiency of the filter bag, and has important practical value.

[0024] In general, this design achieves the goal of efficient dust removal without stopping the machine through innovation in mechanical structure, solves the technical problem that traditional filter bags need to be shut down for dust removal, and effectively improves production efficiency and equipment utilization. At the same time, its automated operation mechanism and reliable protection design also provide strong guarantees for the continuity and stability of industrial production.

A plurality of separation sleeves 211 are installed on each inner rod 21 at equal intervals, and every two follower sleeves 210 symmetrically arranged up and down are respectively fitted on the separation sleeves 211. A limited groove 212 is respectively provided in each follower sleeve 210, and a follower rod 213 is respectively limitedly slidably connected in each limited groove 212, and an intermediate groove 214 is respectively provided in each follower rod 213. A plurality of one-way sleeves 215 are rotatably installed in the middle groove 214, and a one-way block 216 is installed on each one-way sleeve 215. A plurality of one-way grooves 217 are provided on the side wall of the one-way wheel 26 at equal intervals along the axis, and the one-way blocks 216 are stuck in the one-way grooves 217. The same number of baffles 218 as the one-way blocks 216 are installed in the middle groove 214, and a one-way spring 219 is installed on the side of each baffle 218 close to the one-way block 216, and the one-way spring 219 is connected to the one-way block 216.

[0039] When the filter bag is used for emergency and long-term filtering, the smoke on the outside is filtered through the filter bag body 28, and then the corresponding dust adheres to the outside of the filter bag body 28. When the exhaust pressure is detected to be low after long-term use, the wind pressure of the air intake is increased first. Since the filter bag body 28 is attached to multiple attachment frames 32, when the wind pressure increases, the multiple attachment frames 32 will be subjected to a greater force toward the axis, so that the multiple support springs 31 will be compressed. Since the sliding sleeve 33 is slidably connected to the attachment frame 32, the sliding sleeve 33 will move with the movement of the attachment frame 32, and then drive the intermediate spring 35 and the follower rod 213 to slide. The follower sleeve 210 is rotatably connected to the inner rod 21, so the follower sleeve 210 can only rotate along the inner rod 21, and the limit in the up and down directions is guaranteed under the limit action of the separation sleeve 211. With the push of the follower rod 213, the follower rod 213 will slide along the limit groove 212, thereby driving the one-way sleeve 215 to move, and under the action of the one-way spring 219, the one-way block 216 will be stuck in the one-way groove 217 of the one-way wheel 26, thereby driving the one-way wheel 26 to rotate accordingly. Since the one-way wheel 26 is also rotatably connected to the inner rod 21, and the connecting block 27 is connected between the one-way wheel 26 and the rotating The rotating sleeve 22 is on the rotating sleeve 22, which will drive the rotating sleeve 22 and the folding plate 25 to rotate synchronously, and the folding plates 25 on both sides are in a symmetrical setting state. At this time, the upper and lower rotating sleeves 22 rotate towards each other, and the middle circle 23 is fixedly connected to the inner rod 21. Therefore, the two-way springs 24 at both ends will be tightened in the opposite direction, and then the two sides of the two-way spring 24 will store elastic potential energy respectively, and then continue to rotate until the last one-way block 216 is separated from the one-way groove 217. At this time, the one-way spring 219 on the corresponding one-way block 216 will not apply thrust, so the connection with the one-way groove 217 will be released. The elastic potential energy is stored separately. With the disconnection of the one-way block 216 and the one-way groove 217, the elastic potential energy on both sides of the two-way spring 24 is converted into kinetic energy of the rotating sleeve 22, the folding plate 25 and the impact head 29. Then the impact head 29 will quickly rotate and rebound along the internal rod 21. Finally, the impact head 29 hits the inner wall of the filter bag body 28. Multiple impact heads 29 hit synchronously, and then the dust on the outer wall of the filter bag body 28 is shaken off, thereby completing a dust removal process. When active dust removal is needed, it is only necessary to increase the wind pressure without stopping the machine to allow the impact head 29 to impact the filter bag body 28 to complete the dust removal process.

[0040] After completing a dust removal process, the wind pressure is reduced at this time, and then the elastic force of the support spring 31 at this time will be greater than the wind force, so that multiple support springs 31 will rebound to make multiple fitting frames 32 expand outward, and then drive the sliding sleeve 33 to pull backward, and the follower rod 213 will be pulled backward synchronously. At this time, the one-way block 216 closest to the one-way wheel 26 will fit on the one-way groove 217. Due to the unidirectional setting of the one-way groove 217, the one-way block 216 will not be stuck with the one-way wheel 26, and then the one-way block 216 rotates along the one-way sleeve 215 to compress the one-way spring 219, and then the other one-way block 216 also performs the corresponding process, thereby completing the return stroke of the follower rod 213. At this time, the impact head 29 is in a position close to the filter bag body 28, and then the fitting frame 32 is in an expanded state, thereby completing the state reset, and increasing the wind pressure at this time will repeat the above process, and then a second impact will be performed, thereby completing the next dust removal process.

[0041] See also Figures 4 to 7 The pushing mechanism includes a plurality of supporting springs 31 installed at equal intervals on the outside of the frame 12, a fitting frame 32 is installed on each of the four supporting springs 31, a sliding sleeve 33 is vertically slidably connected to the fitting frame 32, the pushing mechanism also includes a receiving seat 34 installed on the follower rod 213, a plurality of intermediate springs 35 are installed on the receiving seat 34, the other ends of the plurality of intermediate springs 35 are connected to the side wall of the sliding sleeve 33, a plurality of follower rods 213 are provided with rounded corners 36 at one end away from the receiving seat 34, and the dust removal mechanism and the pushing mechanism are arranged in no less than six groups along the frame 12.

[0042] When pushing, the one-way block 216 closest to the one-way wheel 26 will move toward the one-way wheel 26, and then the one-way block 216 will be inserted into the one-way groove 217. At this time, the one-way spring 219 is not in a compressed state. As the follower rod 213 continues to push, the one-way block 216 and the one-way wheel 26 are pushed to rotate, and the one-way block 216 rotates along the one-way sleeve 215, so that the one-way spring 219 is compressed, and the thrust provided by the one-way spring 219 ensures the stable clamping between the one-way block 216 and the one-way groove 217. , and then pushes the one-way wheel 26 to rotate, thereby completing the energy storage process of the double-way spring 24, and the next one-way block 216 will also perform the above process. When the one-way spring 219 is compressed to the maximum, as the follower rod 213 continues to push, the one-way spring 219 will reduce the amount of compression, and then the one-way block 216 fits in the position of the one-way groove 217 and crosses to the other side. As the one-way block 216 continues to move, it releases the connection with the one-way groove 217, and then the next one-way block 216 continues the one-way clamping process.

[0043] 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. The scope of the present invention is defined by the attached claims and their equivalents.
