Description

Technical Field

[0001] This utility model relates to the field of baghouse dust collectors, specifically to a cage with an adjustable diameter. Background Technology

[0002] In the current industrial sector where dust emissions are controlled, baghouse dust collectors are widely used. The filter bag is considered the heart of the baghouse dust collector, and it is usually cylindrical and suspended vertically inside the dust collector. When using the filter bag, it must be supported internally by a cage to ensure that the filter bag can still open and be reused even under negative pressure conditions of flue gas.

[0003] However, most dust collector bags are made of polymer synthetic materials, and in high-temperature applications, the bags will inevitably shrink after prolonged use. As the bags shrink, they gradually press against the internal cage frame, or even become directly attached to it, which will have significant negative impacts.

[0004] 1. The cloth bag and cage bones are tightly bound together and cannot be separated. The only way to disassemble the cloth bag and cage bones is through destructive removal, which causes great trouble for the replacement of the cloth bag and cage bones.

[0005] 2. When the filter bags are tightly bound to the cage, the filter bags cannot deform effectively during online dust removal, resulting in ineffective dust removal, increased dust collector resistance, higher energy consumption, and rendering the filter bags unusable.

[0006] 3. The cloth bag is tied tightly to the cage frame. Even if the cloth bag is still strong and breathable, it still has to be replaced, resulting in a great waste.

[0007] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0008] The purpose of this invention is to provide a cage with an adjustable diameter.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] An adjustable diameter cage bone, comprising:

[0011] Multiple elastic longitudinal ribs are arranged in a ring array and fixed between two support rings;

[0012] Multiple elastic transverse ribs are uniformly fixed along the longitudinal direction to the inner side of multiple elastic longitudinal ribs. Each elastic transverse rib is a non-closed ring with a notch, and each end of the notch of the non-closed ring has a hanging ear.

[0013] The transverse rib telescopic assembly drives the two lugs of the non-enclosed annular body to move closer or further apart to adjust the diameter of the non-enclosed annular body.

[0014] Preferably, both the elastic longitudinal ribs and the elastic transverse ribs are elastic steel wires.

[0015] Preferably, the ear loop is formed by curling the two ends of the notch inwards into the ring.

[0016] Preferably, the transverse rib telescopic assembly includes a plurality of adjusting members corresponding one-to-one with the notches of each of the non-closed annular bodies. Each adjusting member includes two adjusting rods, which are inserted into the two hanging ears of the non-closed annular bodies. Under the drive of a driving member, the two adjusting rods drive the two hanging ears to move closer or further apart.

[0017] More preferably, the two adjusting rods are distributed at an acute angle, and the two adjusting rods are respectively inserted into the two hanging ears. The two adjusting rods are driven by the driving member to reciprocate along a longitudinal straight line. The straight distance between the two adjusting rods in contact with the two hanging ears gradually decreases or increases so that the two hanging ears move closer or further apart.

[0018] More preferably, the driving component includes a driving rod, which is fixedly connected to the plurality of adjusting components. The driving rod drives the plurality of adjusting components to reciprocate along a longitudinal straight line via linear drive.

[0019] More preferably, the linear drive includes a threaded sleeve and a bolt, the sleeve being fixed in one of the support rings, the drive rod being rotatably connected to the tail end of the bolt, and the rotating bolt driving the drive rod and the plurality of adjusting members fixed thereon to reciprocate in a longitudinal linear motion.

[0020] More preferably, the drive rod is rotatably connected to the tail end of the screw sleeve via a bearing.

[0021] More preferably, one end of the two adjusting rods is fixedly connected to form the acute angle, and the other end is fixedly connected by a crossbar to form a triangular support.

[0022] More preferably, one of the adjusting rods of each adjusting member is the driving rod.

[0023] The working principle and advantages of this utility model are as follows:

[0024] This invention overcomes the difficulty of using traditional cages on the market, which are composed of closed longitudinal ribs and annular transverse ribs, and require destructive disassembly to remove the filter bag and cage when they are tied together.

[0025] This utility model designs the elastic cross ribs as non-closed rings with notches. The diameter of the cage can be adjusted simply by adjusting the distance between the notches of the elastic cross ribs. The adjustment is made by using bolts and threaded sleeves, which is simple in structure, easy to operate, and will not damage the cloth bag. Attached Figure Description

[0049] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0051] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0052] See appendix Figure 1-7 An adjustable diameter cage includes multiple elastic longitudinal ribs 1, multiple elastic transverse ribs 2, two support rings 3, and a transverse rib telescopic assembly 4.

[0053] in:

[0054] Both the elastic longitudinal rib 1 and the elastic transverse rib 2 are steel wires with a diameter of 3 to 4 mm, and are elastic.

[0055] Multiple elastic longitudinal ribs 1 are arranged in a ring array and fixed between two support rings 3, one of which is a bottom support and the other is a protective sleeve.

[0056] Multiple elastic transverse ribs 2 are evenly fixed along the longitudinal direction to the inner side of multiple elastic longitudinal ribs 1. Each elastic transverse rib 2 is a non-closed ring with a notch 21. Each end of the notch 21 of the non-closed ring has a hanging ear 22. The hanging ear 22 is formed by the two ends of the notch 21 curling inward to avoid damaging the outer cloth bag. In addition, the hanging ear 22 can be ring-shaped to prevent it from coming off the hook.

[0057] The horizontal rib telescopic component 4 drives the two hanging ears 22 of the non-closed ring body to move closer or further apart to adjust the diameter of the non-closed ring body; the two notches 21 move closer or further apart to cause the elastic longitudinal rib 1 to undergo elastic deformation inward or outward of the ring, and the cage bone diameter adjustment operation can separate it from the cloth bag to avoid the cage bone and cloth bag being tied together.

[0058] See appendix Figure 4-7The horizontal rib telescopic assembly 4 includes a plurality of adjusting members 41 corresponding one-to-one with the notches 21 of each of the non-closed annular bodies. Each adjusting member 41 includes two adjusting rods 411, which are inserted into the two hanging ears 22 of the non-closed annular bodies. Under the drive of a driving member 42, the two adjusting rods 411 drive the two hanging ears 22 to move closer or further apart.

[0059] The two adjusting rods 411 are distributed at an acute angle and are respectively inserted into the two hanging ears 22. The two adjusting rods 411 are driven by the driving member 42 to reciprocate in a longitudinal straight line. The straight distance between the two adjusting rods 411 that are in contact with the two hanging ears 22 gradually decreases or increases so that the two hanging ears 22 move closer or further away from each other.

[0060] One end of the two adjusting rods 41 is fixedly connected to form the acute angle, and the other end is fixedly connected by a crossbar 412 to form a triangular support. The crossbar 412 can prevent the adjusting part 41 from detaching from the lug 22.

[0061] The driving component 42 includes a driving rod 421, which is fixedly connected to the plurality of adjusting components 41. The driving rod 421 drives the plurality of adjusting components 41 to reciprocate longitudinally via a linear drive. The linear drive includes a threaded sleeve 422 and a bolt 423. The threaded sleeve 422 is fixed in one of the support rings 3, specifically within a sheath. The driving rod 421 is rotatably connected to the tail end of the bolt 423. The rotating bolt 423 drives the driving rod 421 and the plurality of adjusting components 41 fixed thereon to reciprocate longitudinally. The driving rod 421 is rotatably connected to the tail end of the threaded sleeve 422 via a bearing 424.

[0062] To simplify the structure, one of the adjusting rods 411 of each adjusting member 41 is the driving rod 421.

[0063] When the diameter is not adjusted, the middle part of the adjusting rod 411 can be inserted into the lug part 22, see Figure 4 .

[0064] When adjusting the diameter using the transverse rib telescopic assembly 4, the bolt 423 is turned in the forward direction. The bolt 423 and the threaded sleeve 422 cooperate in rotational and linear motion. The drive rod 421 is connected to the tail end of the bolt 423 through the bearing 424. Therefore, the rotation of the bolt 423 can push the drive rod 421 downward linearly. The drive rod 421 drives multiple adjusting parts 41 to move downward linearly. Figure 5The arrow points downwards. When the two adjusting rods 411 of the adjusting member 41 move downwards, the straight-line distance between the two points of the two adjusting rods 411 that are in contact with the two hanging ears 22 gradually decreases. The two adjusting rods 411 pull the two hanging ears 22 toward the center of the notch 21, so that the two hanging ears 22 move closer to each other, thereby reducing the diameter of the elastic horizontal rib 2. The elastic horizontal rib 2 is fixed with the elastic vertical rib 1, so it can drive the multiple elastic vertical ribs 1 to retract inwards and separate the elastic vertical ribs 1 from the cloth bag.

[0065] When it is necessary to increase the diameter, turn the adjusting bolt 423 in the opposite direction to pull the adjusting longitudinal rib upward. The straight distance between the two points of the two adjusting rods 411 that are in contact with the two hanging ears 22 gradually increases, that is, the two hanging ears 22 gradually move away from each other and open, thereby increasing the diameter of the elastic transverse rib 2. The elastic transverse rib 2 drives the multiple elastic longitudinal ribs 1 to expand outward, and the elastic longitudinal ribs 1 push the cloth bag outward.

[0066] By adjusting the diameter as described above, the cage frame and the cloth bag can be separated, avoiding the problems of replacing and cleaning the cloth bag caused by binding them together.

[0067] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
