[0033] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0034] like Figure 1-6 As shown, the flame-retardant and wear-resistant composite filter bag proposed by the present invention includes an outer bag mechanism and an inner bag mechanism that are combined and sleeved. The outer bag 14 of the outer bag mechanism is externally provided with an outer support rod 12, and the inner bag 23 of the inner bag mechanism is externally provided with an inner support column 22. The inner support column 22 is located in the clamping gap between the outer bag 14 and the inner bag 23;

[0035] The rotating mechanism includes a driving platform 31 disposed below the inner bag 23. A turntable 33 and a support plate 34 are disposed on the driving platform 31. The support plate 34 penetrates the inner cavity of the inner bag 23, and the turntable 33 and the inner bag 23 rotate synchronously.

[0036] The lifting mechanism includes a cylinder 71 arranged below the inner bag 23 , and a retractable telescopic rod 72 is installed on the cylinder 71 . The movable stroke of the inner bag 23 is synchronized with the telescopic rod 72 .

[0037] It should be noted that the outer bag 14 is sleeved on the outer periphery of the inner bag 23, wherein the outer bag 14 is a fixed structure and the inner bag 23 is a movable structure. The inner bag 23 is controlled by a rotating mechanism and can rotate in the inner cavity of the outer bag 14, and is controlled by a lifting mechanism and can be lifted and lowered in the inner cavity of the outer bag 14. The movable design prevents a single point from spontaneous combustion due to heat, and has a certain flame retardant effect.

[0038] In one embodiment, as an example of the rotation movement of the inner bag 23: a rotatable drive shaft 32 is installed at the output end of the drive table 31, and the other end of the drive shaft 32 is connected to the turntable 33, and the turntable 33 and the support plate 34 rotate synchronously. Since the support plate 34 is embedded in the inner cavity of the inner bag 23, the inner bag 23 is controlled by the rotation of the support plate 34 and rotates synchronously. During the rotation process, the dust attached to the bag body itself separates from the inner bag 23 and falls into the gap clamped by the inner and outer bags. At the same time, the inner support column 22 scratches the end face of the outer bag 14 to peel off the dust attached to the surface of the outer bag 14, thereby cleaning the bag body.

[0039] In another embodiment, as an example of the lifting of the inner bag 23: at this time, the lifting mechanism is working, and the cylinder 71 drives the telescopic 72 at the output end to reset, pulling the inner bag 23 downward. During the sliding of the inner bag 23, the inner bag 23 itself is pulled and dust is peeled off from the bag body. At the same time, the inner support column 22 vibrates during the sliding process along the inner wall of the outer bag 14, which assists in the peeling of dust on the outer bag 14 and realizes the cleaning of the bag body.

[0040] In another embodiment, the rotating mechanism and the lifting mechanism work synchronously. During the process of the inner bag 23 being pulled out of the inner cavity of the outer bag 14, the inner bag 23 descends in the vertical direction and rotates in the axial direction. At this time, the inner support column 22 is in a rotating and stirring state, and the dust removal effect is significantly improved compared to the implementation of a single mechanism.

[0041] It should be added that the end face of the inner support column 22 attached to the outer bag 14 is a "corrugated groove" structure, and the raised end face is a smooth chamfered shape; smooth grooves are arranged at intervals on the inner support column 22. On the one hand, when the inner support column 22 is displaced and in contact with the end face attached to the outer bag 14, the gap points are increased, and vibration conduction is generated at multiple points, which facilitates dust cleaning.

[0042] In order to support the outer bag 14, the outer bag mechanism also includes symmetrically arranged outer ring frames 11, which are connected by outer support rods 12. Outer bag clamps 13 for clamping the outer bag 14 are installed at intervals on the outer support rods 12, and the outer bag clamps 13 are used to clamp the outer bag 14 on the outer ring frames 11.

[0043] In order to support the inner bag 23 , the inner bag mechanism further includes symmetrically arranged inner ring frames 21 , which are connected by inner support columns 22 , and the inner ring surfaces of the inner support columns 22 clamp the inner bag 23 .

[0044] The outer support rods 12 and the inner support columns 22 are respectively arranged on the outer peripheries of the outer bag 14 and the inner bag 23 to prevent the vertical rods from hindering the rotation during the rotation process.

[0045] like Figure 4-5 As shown, the screw mechanism includes a screw driver 51 provided on the support plate 34, a screw rack 52 is provided above the screw driver 51, and a screw slide 53 that can slide up and down is provided on the screw rack 52;

[0046] The ventilation mechanism includes a suspension 61 mounted on the screw slide 53, the suspension 61 has a built-in air distribution end seat 62, and a rotatable steering support 65 is provided on the upper part, the steering support 65 is mounted on the air supply end seat 66, and the air supply end seat 66 is mounted on a plurality of raised ventilation pipes 67.

[0047] It should be noted that the screw rack 52 includes a screw 521 arranged in the middle and guide rods 522 located on both sides of the screw 521. The screw 521 is controlled to rotate by the screw driver 51, and the screw slide 53 slides along the guide rods 522.

[0048] In one embodiment, a screw mechanism and a vent mechanism are provided in the inner cavity of the inner bag 23. The screw driver 51 drives the screw 521 on the screw rack 62 to rotate, driving the screw slide 53 to make a linear displacement in the vertical direction along the guide rod 522, thereby adjusting the height of the vent mechanism.

[0049] The gas distribution end seat 62 inhales the clean gas and blows the clean gas from the inside to the outside through the vent pipe 67 on the gas supply end seat 66. The rotation of the rotating mechanism changes the blowing direction. The displacement of the screw slide 53 is coordinated to perform dust cleaning when the inner bag 23 and the outer bag 14 are in a closed and fixed state, thereby solving the problem of blockage of the inner bag 23 and the outer bag 14.

[0050] It should be added that a motor 63 is installed on the side wall of the suspension 61, and a rotatable steering shaft 64 is installed on the output end of the motor 63. The steering shaft 64 penetrates a section of the outer wall of the suspension 61 and is sleeved with a steering support 65. The steering support 65 and the steering shaft 64 rotate synchronously.

[0051] Among them, the fixed ventilation pipe 67 is improved into a rotatable structure, and the steering shaft 64 at the output end is driven to rotate by the motor 63, which drives the steering support 65 to rotate, and the ventilation pipe 67 originally opened toward the inner bag 23 is rotated 90° to a position facing the upper opening of the bag body, and the gas originally used for cleaning and blowing is changed into a cyclone that forms an ascending airflow channel, which helps the gas filtered by the bag body to be discharged outward along the upper opening of the bag body.

[0052] like Figure 6 As shown, the edge of the turntable 33 is formed with a raised guide plate 41 and a limit plate 42, an opening is left between the guide plate 41 and the limit plate 42, and a deformable airbag component 43 is clamped inside, and an air valve 44 for inflation and deflation is installed on the airbag component 43.

[0053] Among them, the purpose of setting up the airbag structure is to seal the contact gap between the inner ring frame 21 and the outer ring frame 11 on the inner bag 23 when the inner bag 23 and the outer bag 14 are attached and closed, so as to prevent the filtered gas from leaking from the gap, and to inflate the inner cavity of the airbag part 43 through the air valve 44. The expanded and deformed airbag part 43 extends to seal the opening left between the guide plate 41 and the limit plate 42.

[0054] like Figure 1 and Figure 7 As shown, the interface mechanism includes an interface end seat 81 arranged above the outer bag 14, a connecting pipe 82 and a collar 83 are installed in the middle of the interface end seat 81, and a gap for a locking channel is left between the connecting pipe 82 and the collar 83.

[0055] It should be noted that the interface mechanism is used to connect the exhaust channel of the external dust removal equipment, clamp the connecting pipe 82 in the channel pipe, and sleeve the external collar 83 on the outer wall of the channel pipe to seal the exhaust channel.

[0056] Alternatively, the collar member 83 is a movable member that slides toward the connecting pipe member 82 , and a sealing ring for auxiliary sealing is clamped between the movable collar member 83 and the channel pipe.

[0057] like Figure 6-7 As shown, when the inner bag 23 and the outer bag 14 are raised and lowered, the original composite filtration can be adjusted to single filtration. The mesh number of the inner bag 23 is higher than that of the outer bag 14. The filtration part can be divided into three stages of filtration: primary filtration, composite filtration and secondary filtration. While meeting the minimum filtration requirements, the filtration interval can be increased to improve the treatment efficiency of dust-laden gas.

[0058] During separation, the dust-laden gas processing capacity is increased;

[0059] When combined, the dust-laden gas treatment effect is improved;

[0060] Switch the filtering mode according to production needs.

[0061] It should be understood that the above-described specific embodiments of the present invention are merely illustrative or illustrative of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included within the scope of protection of the present invention. In addition, the appended claims are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
