Description

Technical Field

[0001] The present application relates to the field of medicinal material processing, and in particular to a pulse dust collector used for medicinal material processing. Background Art

[0002] In the process of processing Chinese medicinal materials, they need to be crushed. The crushing process will cause the medicinal powder to be released into the air, thereby causing air pollution. At this time, dust removal equipment will be needed to treat the waste gas generated in the crushing process.

[0003] At present, the dust removal equipment commonly used in the processing of medicinal materials is the pulse dust collector. Figure 1 The pulse dust collector mainly includes a shell 1, a dust removal device 2 installed inside the shell 1, and an ash hopper 11 installed at the lower end of the shell 1. An air inlet 12 is opened on one side of the shell 1, and the air inlet 12 is located at the lower end of the dust removal device 2; an air outlet 13 is opened on one side of the shell 1, and the air outlet 13 is located at the upper end of the dust removal device 2. Among them, the dust removal device 2 includes a support plate 21 fixedly connected to the inside of the shell 1, a plurality of support cages 22 plugged into the support plate 21, and a dust bag 23 sleeved on each support cage 22. The support cage 22 can support and fix the dust bag 23. The exhaust gas enters from the air inlet 12 and is discharged from the air outlet 13. In the process of the exhaust gas reaching the air outlet 13 from the air inlet 12, the dust in the exhaust gas will be filtered by the dust bag 23 and fall into the ash hopper 11 under the action of gravity to achieve dust removal. During the use of the pulse dust collector, when the support cage 22 is damaged or the dust bag needs to be replaced, the support cage 22 needs to be pulled out of the mounting hole on the support plate as a whole, and a new support cage 22 needs to be installed on the support plate 21.

[0004] However, due to the large size of the dust collector, the length of the support cage itself can reach several meters, so when the support cage is pulled out of the dust collector, sufficient space must be left above the dust collector. If the height space is limited, it is difficult to disassemble and assemble the support cage. When it is pulled out, it is very troublesome to replace it because of its long length. Summary of the invention

[0005] In order to reduce the limitations of space constraints on the disassembly and assembly of the support cage and improve the convenience of replacement, the present application provides a pulse dust collector for medicinal material processing.

[0006] The pulse dust collector for medicinal material processing provided in this application adopts the following technical solution:

[0007] A pulse dust collector for medicinal material processing, comprising a housing and a dust removal device installed in the housing. The dust removal device includes a support plate fixedly connected in the housing, a plurality of support cages inserted on the support plate, and dust removal bags sleeved on each support cage. The support cage includes a plurality of support telescopic rods connected end to end. Each support telescopic rod includes a plurality of cylinders sleeved in sequence. A first connection component for fixing the relative position between two adjacent cylinders is arranged between two adjacent cylinders. Each cylinder includes a first mounting ring, a second mounting ring, and a plurality of connecting rods detachably connected between the first mounting ring and the second mounting ring. The plurality of connecting rods are arranged at intervals around the axis of the first mounting ring and / or the second mounting ring.

[0008] By adopting the above technical solution, when it is necessary to remove the support cage, each cylinder can be pulled out to operate the telescopic movement of the support telescopic rod, and finally the plurality of cylinders can be retracted into one cylinder. After pulling out one support telescopic rod, by releasing the connection relationship between two adjacent support telescopic rods, the support telescopic rod can be taken out, occupying less space. And in actual application, cylinders with appropriate lengths can also be selected according to the actual space size and assembled, greatly reducing the limitations brought by space constraints during the disassembly and assembly of the support cage. Moreover, since the length of the support telescopic rods after being shrunk together is limited, the operation is more convenient, greatly improving the convenience during replacement.

[0009] Optionally, among the plurality of cylinders sleeved in sequence, for two adjacent ones, the one located on the outside is called the first cylinder, and the cylinder slidingly connected inside the first cylinder is called the second cylinder. The first connection component includes a first fixed cover slidingly connected to the second cylinder. The first fixed cover is in the shape of one end being open, and its open end faces the first cylinder. The first fixed cover is threadedly connected to the first cylinder, and a first fixed space for inserting the end of the first cylinder is formed between the first fixed cover and the second cylinder.

[0010] By adopting the above technical solution, during installation, directly screw the first fixed cover onto the first cylinder. As the first fixed cover is screwed onto the first cylinder for a longer distance, the first cylinder is also inserted into the first fixed space, and the second cylinder is also inserted into the first cylinder, realizing the installation and fixation of the first cylinder and the second cylinder, and the fixation is very stable.

[0011] Optionally, a limiting member for restricting the sliding position of the first fixed cover on the second cylinder is arranged on the second cylinder. The limiting member includes a first fixed cylinder threadedly connected to the end of the second cylinder and a second fixed cylinder fixedly connected to the other end of the second cylinder. The first fixed cover is slidingly connected between the first fixed cylinder and the second fixed cylinder.

[0012] By adopting the above technical solution, when the second cylinder slides into the first cylinder, the first fixed cover also slides on the second cylinder. The settings of the first fixed cylinder and the second fixed cylinder enable the first fixed cover to only slide between the first fixed cylinder and the second fixed cylinder, thereby fixing the limit position of the sliding of the first fixed cover and preventing the first fixed cover from slipping off the second cylinder.

[0013] Optionally, a fixing component for fixing the position of each cylinder on the support plate is provided on the support plate. When two adjacent cylinders are fixed together, the fixing component can fix the position of the cylinder on the support plate.

[0014] By adopting the above technical solution, when the staff needs to fix two cylinders together, the position of the cylinders on the support plate can be fixed through the fixing component, which is more convenient for the staff to install and fix the two cylinders, and greatly reduces the probability of the two cylinders slipping off the support plate when the staff fixes the two cylinders.

[0015] Optionally, a plurality of the fixing components are provided, and each fixing component is arranged at the installation position of each support cage. The fixing component includes a hoop arranged on the support plate and a driving member for controlling the automatic opening or closing of the hoop. When two adjacent cylinders need to be fixed together, the driving member can control the hoop to close to clamp the cylinder.

[0016] By adopting the above technical solution, when installing each support cage, the hoop can be used to clamp the installed part of the support cage to fix the position of the cylinder on the support plate.

[0017] Optionally, an abutting ring is slidably connected to each first cylinder, and the abutting ring is located on the side of the first fixed cover away from its opening. When the hoop clamps the cylinder, the abutting ring abuts against the hoop.

[0018] By adopting the above technical solution, when the hoop clamps the cylinder, the hoop abuts against the abutting ring, which will not affect the operation of fixing the other cylinder by the first fixed cover.

[0019] Optionally, the hoop includes a first half-ring hinged to the support plate at one end and a second half-ring hinged to the support plate at one end. A first mounting plate is fixedly connected to the end of the first half-ring away from its hinge axis, and a second mounting plate is fixedly connected to the end of the second half-ring away from its hinge axis. The driving member includes an electric push rod hinged between the first mounting plate and the second mounting plate.

[0020] By adopting the above technical solution, the first mounting plate and the second mounting plate can be driven to approach or move away from each other relatively by controlling the extension or retraction of the push rod of the electric push rod, so as to control the opening or closing of the hoop.

[0021] Optionally, a pressing component is provided on one side of the first half-ring facing the second half-ring and on one side of the second half-ring facing the first half-ring. The pressing component includes a pressing ring located on one side of the first half-ring facing the second half-ring, a pressing spring fixedly connected between the first half-ring and the abutting ring, and a guiding telescopic rod fixedly connected between the first half-ring and the pressing ring.

[0022] By adopting the above technical solution, when the electric push rod drives the first mounting plate and the second mounting plate to approach each other relatively so that the hoop is closed, if there is a gap between the hoop and the support cage at this time, the abutting ring will tightly abut against the side wall of the support cage under the action of the pressing spring, so that cylinders with different diameter sizes can be supported and fixed, and the application range is wider.

[0023] Optionally, a second connecting component is provided between two adjacent groups of the support telescopic rods. The second connecting component includes a connecting threaded cylinder fixedly connected to one end of the second cylinder away from the first cylinder, and a second fixing cover rotatably connected to one end of the first cylinder away from the second cylinder. The second fixing cover is threadedly connected to the connecting threaded cylinder, and a second fixing space for the connecting threaded cylinder to be inserted is formed between the second fixing cover and the first cylinder.

[0024] By adopting the above technical solution, by screwing the second fixing cover onto the connecting threaded cylinder, at this time the connecting threaded cylinder will be inserted into the second fixing space, so that the relative position between the second fixing cover and the connecting threaded cylinder can be fixed, and the connection of the two support telescopic rods can be realized.

[0025] Optionally, threaded rods are fixedly connected to both ends of the connecting rod. Threaded holes for the threaded rods to be screwed into are provided on one side of the first mounting ring and on one side of the second mounting ring. The threaded directions of the threaded rods at both ends of the connecting rod are opposite.

[0026] By adopting the above technical solution, by screwing the connecting rod, the threaded rods at both ends can be respectively screwed into the first mounting ring and the second mounting ring, and the installation of the cylinder can be realized.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The present application is formed by connecting a plurality of support telescopic rods to the support cage, so that during disassembly, each support telescopic rod can be disassembled in sequence, and the disassembled support telescopic rod can also automatically contract. When installed, it automatically extends under the action of gravity, making the operation more convenient. Moreover, the space occupied by the contracted support telescopic rod is less, greatly reducing the limitation of space during the disassembly and assembly of the support cage and providing convenience during replacement.

[0029] 2. The setting of the fixing component enables the position of the installed support telescopic rod to be fixed by the fixing component when connecting two adjacent support telescopic rods together, facilitating the connection of the two support telescopic rods. Moreover, when the support cage is installed, the position of the support cage on the support plate can also be fixed by the fixing component.

[0030] 3. The setting of the clip enables the position of the dust removal bag to be fixed by the clip when installing the support cage, facilitating the installation of the support cage by the staff. Description of the Drawings

Detailed implementation manners

[0036] The following further describes the present application in detail with reference to the Figures 2 - 4 accompanying drawings.

[0037] An embodiment of the present application discloses a pulse dust collector for medicinal material processing. Referring to Figure 2 , the pulse dust collector for medicinal material processing includes a housing 1 and a dust removal device 2 installed in the housing 1.

[0038] Among them, a dust hopper 11 is installed on the lower side of the housing 1, an air inlet 12 is provided on one side of the housing 1, an air outlet 13 is provided on the other side of the housing 1, and the dust removal device 2 is installed between the air inlet 12 and the air outlet 13. When the waste gas enters from the air inlet 12, it will flow towards the air outlet 13. When the waste gas reaches the dust removal device 2, the dust in the waste gas will be blocked by the dust removal device 2 and fall into the dust hopper 11 under the action of gravity, while the gas will pass through the dust removal device 2 and be discharged from the air outlet 13.

[0039] Among them, the dust removal device 2 includes a support plate 21 fixedly connected in the housing 1, a plurality of support cages 22 inserted on the support plate 21, and dust removal bags 23 sleeved on each support cage 22. The support cages 22 can provide support for the dust removal bags 23, and the dust removal bags 23 can filter out impurities in the waste gas.

[0040] Referring to Figure 2 , a plurality of installation holes 211 for inserting the support cages 22 are provided on the support plate 21. The support cages 22 include a plurality of support telescopic rods connected end to end, and a second connection component 3 is arranged between adjacent two support telescopic rods to realize the connection of adjacent two support telescopic rods. In the present application, it is described by taking the support telescopic rods having two as an example.

[0041] Referring to Figure 3 , each support telescopic rod includes a plurality of cylinders 221 sleeved in sequence, and a first connection component 4 for fixing the relative positions of two adjacent cylinders 221 is arranged between adjacent two cylinders 221. In the present application, it is described by taking each support telescopic rod including two cylinders 221 sleeved together as an example, and one of the cylinders 221 located on the outside is called the first cylinder 222, and one of the cylinders 221 slidably connected in the first cylinder 222 is called the second cylinder 223.

[0042] The first connection component 4 includes a first fixed cover 41 sleeved on the second cylinder 223. The first fixed cover 41 is slidably connected to the second cylinder 223 and can rotate relative to the second cylinder 223. The first fixed cover 41 is open at one end, and its open end faces the first cylinder 222. A circular first fixed space 42 for inserting the end of the first cylinder 222 is formed between the inner wall of the first fixed cover 41 and the outer wall of the second cylinder 223. And an internal thread is machined inside the first fixed cover 41, and an external thread is machined at one end of the first cylinder 222 facing the second cylinder 223. The first fixed cover 41 can be screwed onto the first cylinder 222 to realize the connection between the first cylinder 222 and the second cylinder 223.

[0043] A limiting member 5 for fixing the sliding limit position of the first fixed cover 41 on the second cylinder 223 is provided on the second cylinder 223. The limiting member 5 includes a first fixed cylinder 51 threadedly connected to one end of the second cylinder 223 and a second fixed cylinder 52 fixedly connected to the other end of the second cylinder 223. The first fixed cover 41 is located between the first fixed cylinder 51 and the second fixed cylinder 52. And the opening of the first fixed cover 41 faces the first fixed cylinder 51. When it is necessary to connect the first cylinder 222 and the second cylinder 223, the first fixed cover 41 is directly screwed onto the end of the first cylinder 222. At this time, the second fixed cylinder 52 will also be inserted into the first cylinder 222, and the first cylinder 222 will be inserted into the first fixed space 42 to realize the connection between the first cylinder 222 and the second cylinder 223. At the same time, the first fixed cylinder 51 will also limit the extreme position of the first fixed cover 41 at the end close to the first fixed cylinder 51. At the same time, during actual installation and use, the first cylinder 222 is located above the second cylinder 223, so that the first fixed cover 41 will not slide in the direction of the second fixed cylinder 52 under the action of gravity. And when it is necessary to retract the second cylinder 223 into the first cylinder 222, the first cylinder 222 is directly operated to slide in the second cylinder 223 until the first fixed cover 41 slides to the second fixed cylinder 52 to complete the contraction of the support telescopic rod.

[0044] Refer to Figure 3 , the second connection component 3 is arranged between the first cylinder 222 of one support telescopic rod and the second cylinder 223 of another support telescopic rod, and is used to connect the first cylinder 222 of one support telescopic rod to the second cylinder 223 of another support telescopic rod to realize the connection between two adjacent support telescopic rods.

[0045] Specifically, the second connecting component 3 includes a second fixed cover 31 rotatably connected to the first cylinder 222 and a connecting threaded cylinder 32 fixedly connected to the end of the second cylinder 223. The diameter of the connecting threaded cylinder 32 is larger than that of the second cylinder 223. The second fixed cover 31 is also open at one end, and the opening of the second fixed cover 31 faces the other supporting telescopic rod. A second fixed space 33 for inserting the connecting threaded cylinder 32 on the other supporting telescopic rod is formed between the second fixed cover 31 and the first cylinder 222. An internal thread is machined on the inner wall of the second fixed cover 31, and an external thread is machined on the connecting threaded cylinder 32, so that the second fixed cover 31 can be screwed onto the connecting threaded cylinder 32 to realize the connection of two adjacent supporting telescopic rods.

[0046] When installing the support cage 22 on the support plate 21, it is necessary to first insert the dust removal bag 23 into the installation hole 211, and then sequentially place one by one the supporting telescopic rods into the dust removal bag 23. And after inserting one second cylinder 223 into the dust removal bag 23, it is necessary to operate the second cylinder 223 to extend from the first cylinder 222 until the closed end of the first fixed cover 41 abuts against the first fixed cylinder 51 to realize the elongation of the supporting telescopic rod. Then, another supporting telescopic rod is connected above the supporting telescopic rod through the second fixed cover 31. Since when connecting two adjacent supporting telescopic rods, it is necessary to hold the supporting telescopic rod below with one hand, support the supporting telescopic rod above with the other hand, and then operate the second connecting component 3 to connect the two supporting telescopic rods, the installation is also relatively difficult. And when the supporting telescopic rod below is not held firmly, it is very easy for the supporting telescopic rod to fall and damage the equipment.

[0047] Refer to Figure 3 and Figure 4 , therefore, a fixing component 6 for supporting the position of the telescopic rod on the support plate 21 is also provided on the support plate 21. When it is necessary to connect two adjacent supporting telescopic rods together, the position of the supporting telescopic rod on the support plate 21 can be fixed by the fixing component 6, and the staff only needs to connect the two supporting telescopic rods together through the second connecting component 3.

[0048] Specifically, a plurality of fixing components 6 are also provided. Each fixing component 6 is located at each installation hole 211 to fix the support cage 22 inserted at each installation hole 211. Each fixing component 6 includes a hoop 61 provided on the support plate 21 and a driving member 62 for controlling the automatic opening or closing of the hoop 61. Among them, the axis of the hoop 61 when closed coincides with the axis of the installation hole 211, so that by driving the hoop 61 to close through the driving member 62, the cylinder body 221 can be clamped by the hoop 61 to fix the position of the cylinder body 221 on the support.

[0049] Refer to Figure 4, the hoop 61 includes a first half-ring 611 with one end hinged to the support plate 21 and a second half-ring 612 with one end hinged to the support plate 21. The hinge axes of the first half-ring 611 and the second half-ring 612 coincide, and the arc openings of the first half-ring 611 and the second half-ring 612 face each other. A first mounting plate 613 is fixedly connected to the end of the first half-ring 611 away from its hinge axis, and a second mounting plate 614 is fixedly connected to the end of the second half-ring 612 away from its hinge axis. Two ends of the driving member 62 are respectively hinged to the first mounting plate 613 and the second mounting plate 614.

[0050] The driving member 62 can be an electric push rod, a cylinder, etc. In this application, the driving member 62 is taken as an example of an electric push rod for illustration. By operating the push rod of the electric push rod to extend or retract, the first mounting plate 613 and the second mounting plate 614 can be driven to approach or move away from each other relatively, and then drive the first half-ring 611 and the second half-ring to rotate around their hinge axes with the support plate 21, so as to realize the opening or closing of the hoop 61. Moreover, since two ends of the driving member 62 are respectively hinged to the first mounting plate 613 and the second mounting plate 614, there will be no jamming phenomenon.

[0051] After inserting a support telescopic rod into the dust removal bag 23, the position of the inserted support telescopic rod relative to the support plate 21 can be fixed by the hoop 61. Then, hold the support telescopic rod to be installed with one hand and screw the second fixing cover 31 with the other hand to connect two adjacent support telescopic rods together, which makes the installation more convenient.

[0052] Refer to Figure 3 , in order to prevent the cylinder body 221 from sliding in the hoop 61 under the influence of gravity when the hoop 61 clamps the cylinder body 221, so that the hoop 61 abuts against the second fixing cover 31 and affects the rotation of the second fixing cover 31 by the staff. A contact ring 7 is sleeved on each cylinder body 221, and a bearing 71 is fixedly connected between the contact ring 7 and the second fixing cover 31. When the hoop 61 clamps the first cylinder 222 of the support telescopic rod, if the first cylinder 222 slides in the hoop 61, the hoop 61 will abut against the contact ring 7, and due to the setting of the bearing 71, the rotation of the second fixing cover 31 will not be affected.

[0053] Refer to Figure 4In order to enable the clamping hoop 61 to clamp and fix the cylinder 221 of different diameters, and to make the clamping hoop 61 to the cylinder 221 more firmly. A tightening assembly 8 is provided on the side of the first half ring 611 facing the second half ring 612 and on the side of the second half ring 612 facing the first half ring 611. The tightening assembly 8 includes a tightening ring 81 located on the side of the first half ring 611 facing the second half ring 612, a tightening spring 82 fixed between the first half ring 611 and the tightening ring 81, and a guiding telescopic rod 83 fixed between the first half ring 611 and the tightening ring 81. When the first half ring 611 and the second half ring 612 are closed, the tightening ring 81 can always be in contact with the cylinder 221 under the action of the tightening spring 82, so as to achieve the clamping and fixing of different direct cylinders 221. The guiding telescopic rod 83 can guide the abutting ring 7 on one hand, and can also increase the supporting strength of the abutting ring 7 on the other hand, so as to prevent the abutting ring 7 from sliding down under the gravity of the cylinder 221 .

[0054] At the same time, in order to ensure that each time the electric push rod drives the clamp 61 to open or close, the first half ring 611 and the second half ring 612 can move simultaneously, and the axis of the clamp 61 after closing will not be misaligned with the axis of the mounting hole 211 due to inconsistent movements, a straightening assembly 9 for straightening the first half ring 611 and the second half ring 612 is provided on the support plate 21.

[0055] The straightening assembly 9 includes two straightening plates 91 fixedly connected to the support plate 21, a first straightening spring 92 fixedly connected between one straightening plate 91 and the first mounting plate 613, and a second straightening spring 93 fixedly connected between the other straightening plate 91 and the second mounting plate 614. The first mounting plate 613 and the second mounting plate 614 are located between the two straightening plates 91. The first straightening spring 92 and the second straightening spring 93 can make the first mounting plate 613 and the second mounting plate 614 move synchronously.

[0056] Furthermore, rollers 615 are rotatably connected to the first mounting plate 613 and the second mounting plate 614 on one side facing the support plate 21, thereby converting the sliding friction between the first mounting plate 613 and the support plate 21 and between the second mounting plate 614 and the support plate 21 into rolling friction, making the first mounting plate 613 and the second mounting plate 614 slide more smoothly.

[0057] Reference Figure 4 A clip 63 is also fixed to the hinge axis of the first mounting plate 613 and the second mounting plate 614. When the dust bag 23 is placed in the mounting hole 211, the open end of the dust bag 23 can be clamped by the clip 63, and then the staff can directly put multiple supporting telescopic rods into the dust bag 23 one by one.

[0058] Reference Figure 3, a fastening cover 24 is also detachably connected to the upper end of the support cage 22. The fastening cover 24 can be inserted into the second fixing space 33 and is threadedly connected to the second fixing cover 31 of the uppermost support telescopic rod. After the installation of the support cage 22 is completed, the fixing relationship between the clip 63 and the dust removal bag 23 can be released, and then the open end of the dust removal bag 23 is placed into the second fixing space 33 on the uppermost support telescopic rod, and then the fastening cover 24 is installed on the support cage 22, so that the position of the dust removal bag 23 on the support cage 22 can be fixed by the fastening cover 24, and the installation is more convenient and stable.

[0059] Referring to Figure 3 , each cylinder body 221 includes a first mounting ring 2211, a first mounting ring 2211, and a plurality of connecting rods 2213 detachably connected between the first mounting ring 2211 and the second mounting ring 2212. The plurality of connecting rods 2213 are arranged at intervals around the axis of the first mounting ring 2211 and / or the second mounting ring 2212, so that a flow channel for gas to flow through is formed between two adjacent connecting rods 2213.

[0060] Specifically, threaded rods 2214 are fixedly connected to both ends of the connecting rod 2213. Threaded holes for the threaded rods 2214 to be screwed into are formed on one side of the first mounting ring 2211 and the second mounting ring 2212, and the threaded directions of the threaded rods 2214 at both ends of the connecting rod 2213 are opposite. During installation, the two threaded rods 2214 at both ends of the connecting rod 2213 are directly abutted against the threaded holes at the corresponding positions on the first mounting ring 2211 and the second mounting ring 2212, and then the connecting rod 2213 is rotated, which can drive the two threaded rods at both ends of the connecting rod 2213 to be screwed into the threaded holes on the first mounting ring 2211 and the second mounting ring 2212 at the same time. The installation and disassembly are very convenient. When the cylinder body 221 is damaged, the damaged part can also be replaced separately. Of course, the staff can also select a connecting rod 2213 with a suitable length according to needs, and the use is more flexible.

[0061] The implementation principle of a pulse dust collector for medicinal material processing in an embodiment of the present application is as follows: When it is necessary to install or disassemble the support cage 22, directly open the door at the upper end of the housing 1, remove the fastening cover 24, clamp the open end of the dust removal bag 23 on the clip 63, control the hoop 61 to open, and the staff can pull out a support telescopic rod upward. When pulling out the second cylinder 223 upward, the second cylinder 223 will also shrink into the first cylinder 222 until the entire support telescopic rod is pulled out. Then, hold the unextracted part with the hoop 61 and unscrew the second fixing cover 31 to release the locking relationship between adjacent support telescopic rods. Then control the hoop 61 to open and repeat the process until the entire support cage 22 is taken out. Then the staff releases the fixing relationship between the clip 63 and the dust removal bag 23 and takes out the dust removal bag 23. When reinstalling, directly place the dust removal bag 23 in the installation hole 211 and fix the open end of the dust removal bag 23 with the clip 63. Then insert a support telescopic rod into the dust removal bag 23, and the second cylinder 223 is also pulled out from the first cylinder 222 until the first fixed cylinder 51 abuts against the closed end of the first fixing cover 41. Then clamp the second cylinder 223 on the inserted support telescopic rod with the hoop 61, and the staff directly unscrews the second fixing cover 31 to connect the two support telescopic rods together. Repeat the process until all the support telescopic rods are installed in the dust removal bag 23. Finally, fix the position of the support cage 22 with the hoop 61, release the fixing relationship between the clip 63 and the dust removal bag 23, place the open end of the dust removal bag 23 into the second fixing space 33 at the uppermost end of the support cage 22, and screw the fastening cover 24 onto the upper end of the support cage 22 to fix the relative position between the dust removal bag 23 and the support cage 22, completing the installation. Since each cylinder body 221 is detachably connected throughout the process, the support cage 22 can be taken out in sections, greatly reducing the limitation of space during the disassembly and assembly of the support cage 22 and improving the convenience during replacement. Moreover, due to the setting of the support telescopic rod, when taking out the cylinder body 221, two adjacent cylinder bodies 221 can be sleeved together, saving more floor space after taking them out.

[0062] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
