Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bag-type dust removal frames, in particular to a bag-type dust removal frame. Background Art
[0002] Bag dust collector is a highly efficient and commonly used dust collector. The cross-sectional shapes of the bags used are of two types: one is round and the other is flat square. The filtration area of these two types of bags is the circumference multiplied by the length. The space inside and outside the bag is idle and cannot be fully utilized, so the filtration area is limited.
[0003] In the prior art, a Chinese patent with authorization announcement number CN215742436U discloses a bag-type dust removal skeleton, wherein the bag is provided with a supporting device, a buffering device and a connecting device, wherein the supporting device comprises an inner skeleton mechanism and an outer skeleton mechanism, wherein the inner skeleton mechanism comprises an inner cross beam, an inner longitudinal beam and an inner baffle plate, wherein a plurality of the inner cross beams, inner longitudinal beams and inner baffle plates are provided, and the two ends of the plurality of inner longitudinal beams are respectively connected to the two inner cross beams, and the plurality of inner baffle plates are connected to the inner longitudinal beams at one end, and the other end is fitted to the inner side of the bag. By providing a supporting device, the bag can be supported by the inner skeleton mechanism and the outer skeleton mechanism at the same time, thereby increasing the contact area between the bag and the air under the same footprint.
[0004] The above-mentioned prior art solution has the following defects: adjacent outer beams are connected by springs, and the elastic force of the springs is used to make the exoskeleton mechanism move radially as the cloth bag is contracted and expanded. When resetting inward, the direction of the force applied by the spring to the exoskeleton can be decomposed into tangential and radial directions. Due to the installation orientation of the spring, the radial force is extremely small and the traction force on the exoskeleton mechanism is very limited. Therefore, it is very easy for the exoskeleton mechanism to be unable to move inward and reset and get stuck.
[0005] For this reason, a bag-type dust removal framework is proposed. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0008] A bag-type dust removal skeleton comprises a base, the top surface of the base is provided with a radial elastic moving mechanism, the number of the radial elastic moving mechanisms is several and they are evenly distributed in a ring array, a moving seat is fixedly mounted on the surface of the radial elastic moving mechanism, the moving seat is slidably arranged relative to the top surface of the base, an outer frame is fixedly mounted on the top surface of the moving seat, an inner frame is fixedly mounted on the top surface of the base, the outer frame is arranged on the periphery of the inner frame, a wire groove is opened inside the outer frame, and elastic rings are passed through a plurality of the wire grooves.

[0026] like Figures 1 to 4 As shown, a bag-type dust removal skeleton includes a base 1, a radial elastic moving mechanism 2 is provided on the top surface of the base 1, the number of the radial elastic moving mechanisms 2 is several and they are evenly distributed in a ring array, a moving seat 3 is fixedly installed on the surface of the radial elastic moving mechanism 2, the moving seat 3 is slidably arranged relative to the top surface of the base 1, an outer frame 4 is fixedly installed on the top surface of the moving seat 3, an inner frame 5 is fixedly installed on the top surface of the base 1, the outer frame 4 is arranged on the periphery of the inner frame 5, a wire groove 6 is opened inside the outer frame 4, and elastic rings 7 are passed through the inside of the wire grooves 6.
[0027] More specifically, as the cloth bag expands, an outward radial force is applied to the outer frame 4, causing the outer frame 4 to move outward, exposing the elastic rings 7 between several outer frames 4, so that the elastic rings 7 serve as transverse connectors between adjacent outer frames 4 to tighten the cloth bag and prevent the cloth bag from being damaged due to excessive expansion. At the same time, the outer frame 4 drives the radial elastic moving mechanism 2 to undergo elastic deformation through the moving seat 3. When the cloth bag shrinks, the radial elastic moving mechanism 2 recovers its deformation and applies a force to the moving seat 3 in the radial direction, causing several outer frames 4 to move radially smoothly, so that several outer frames 4 are reset, effectively avoiding the situation where the radial force is too small and the outer frame 4 is stuck and cannot be reset.
[0028] The radial elastic moving mechanism 2 includes a T-shaped slide groove 201, which is opened on the top surface of the base 1. A T-shaped slider 202 and a blocking block 203 are slidably installed on the inner wall surface of the T-shaped slide groove 201. The top surface of the T-shaped slider 202 is fixedly connected to the moving seat 3. A blocking block 203 is provided on the inner wall surface of the T-shaped slide groove 201. The surface of the blocking block 203 is flush with the outer surface of the base 1. A spring 204 is fixedly connected between the opposite surfaces of the T-shaped slider 202 and the blocking block 203.
[0029] Specifically, when the cloth bag expands, the outer frame 4 drives the movable seat 3 to move centrifugally, and then drives the T-shaped slider 202 to move radially outward through the movable seat 3. The distance between the T-shaped slider 202 and the blocking block 203 is reduced, so that the spring 204 is squeezed and deformed. When the cloth bag shrinks, the spring 204 restores its deformation, pushing the T-shaped slider 202 to move centripetally along the surface of the T-shaped slide groove 201, and then drives the movable seat 3 and the outer frame 4 to move centripetally, so that the outer frame 4 is quickly and smoothly reset.
[0030] The blocking block 203 is slidably arranged relative to the inner surface of the T-shaped slide groove 201. The surface of the blocking block 203 and the bottom surface of the inner wall of the T-shaped slide groove 201 are both provided with threaded holes, and fixing bolts 205 are threadedly installed on the surface of the threaded holes.
[0031] Specifically, the blocking block 203 is fixed relative to the surface of the T-shaped slide groove 201 by the fixing bolt 205. When the spring 204 and other structures need to be repaired or replaced, the fixing bolt 205 is rotated and removed, and the blocking block 203 can be slid out relative to the surface of the T-shaped slide groove 201, thereby facilitating the repair and replacement of the spring 204 and other structures.
[0032] The outer frame 4 includes an outer cross bar 401, an outer longitudinal bar 402 and an outer push plate 403. The outer cross bar 401 is an arc-shaped cross bar. The number of outer cross bars 401 is several and they are evenly distributed longitudinally. The outer longitudinal bar 402 is fixedly installed between the upper and lower adjacent outer cross bars 401. The outer push plate 403 is fixedly installed on the side surface of the outer cross bar 401 close to the inner frame 5, and the outer push plate 403 is radially arranged.
[0033] Specifically, the outer horizontal rod 401 and the outer longitudinal rod 402 cooperate to form a stable and reliable mesh structure, thereby fixing the outer push plate 403.
[0034] The inner frame 5 includes an inner base 501, an inner cross bar 502 and an inner longitudinal bar 503. The inner base 501 is fixedly installed on the top surface of the base 1. The number of inner cross bars 502 is several and they are evenly distributed longitudinally. The inner longitudinal bar 503 is fixedly installed between adjacent inner cross bars 502. An inner push plate 504 is fixedly installed on the outer surface of the inner cross bar 502. The inner push plate 504 is radially arranged and spaced apart from the outer push plate 403.
[0035] Specifically, the inner base 501, the inner cross bar 502 and the inner longitudinal bar 503 cooperate to form a stable and reliable cylindrical mesh structure, so as to fix the inner push plate 504. The inner push plate 504 and the outer push plate 403 are arranged at intervals so that the surface of the bag is folded, which can effectively increase the side area of the bag, improve the filtering and dust removal efficiency and reduce the volume of the bag, and can also squeeze the bag to avoid excessive expansion and damage.
[0036] The wire groove 6 is provided inside the outer cross bar 401 , and the elastic ring 7 is passed through the wire groove 6 at the same height.
[0037] Specifically, several outer cross bars 401 of the same height are connected by elastic rings 7, so that after the outer cross bars 401 move centrifugally, elastic rings 7 are still present between each other as transverse connectors, thereby avoiding gaps between adjacent outer frames 4 and causing the bags to be squeezed out of the gaps.
[0038] In summary: as the cloth bag expands, an outward radial force is applied to the outer frame 4, causing the outer frame 4 to move outward, exposing the elastic rings 7 between several outer frames 4, so that the elastic rings 7 serve as transverse connectors between adjacent outer frames 4 to tighten the cloth bag and prevent the cloth bag from being damaged due to excessive expansion. At the same time, the outer frame 4 drives the radial elastic moving mechanism 2 to undergo elastic deformation through the moving seat 3. When the cloth bag shrinks, the radial elastic moving mechanism 2 recovers its deformation and applies a force to the moving seat 3 in the radial direction, causing several outer frames 4 to move radially smoothly, so that several outer frames 4 are reset, effectively avoiding the situation where the radial force is too small and the outer frame 4 is stuck and cannot be reset.
