Technical Field
[0001] This utility model belongs to the field of telescopic chimney technology, and in particular relates to a telescopic chimney device. Background Technology
[0002] Retractable chimneys, as a new type of emission facility that breaks through the traditional rigid structure, are designed with the core concept of achieving highly dynamic adjustment through the combination of flexible materials and mechanical structures. These chimneys typically use lightweight composite materials (such as high-strength polyester film or thin metal alloy sheets) as the main pipe, coupled with a hydraulic / pneumatic lifting system or cable traction device, allowing them to freely extend and retract within a range according to actual needs. Compared to fixed-height concrete or steel chimneys, their modular design allows for segmented folding and storage, significantly reducing transportation and storage space requirements.
[0003] Compared with Chinese Patent CN206891207U, a telescopic chimney that moves with the kiln is disclosed, including a chimney body, the chimney body including a bottom cylinder and a telescopic cylinder, the bottom cylinder including an inner cylinder and an outer cylinder, the outer cylinder being fitted outside the inner cylinder, the upper end of the outer cylinder being sealed to the inner cylinder, the gap between the outer cylinder and the inner cylinder forming a flue gas channel, the outer cylinder having a flue gas inlet communicating with the flue gas channel, the flue gas channel outlet communicating with the bottom opening of the inner cylinder, the top of the bottom cylinder having a telescopic cylinder communicating with the bottom cylinder fixed, the top of the bottom cylinder and the telescopic cylinder in the extended state having a height (sum of lengths) of not less than 15m above the ground, the structure is simple and the production cost is low, successfully solving the problem of flue gas from mobile tunnel brick kilns being emitted at a height of more than 15m, and can effectively discharge the flue gas purified by mobile tunnel brick kilns at high altitude, achieving the requirements of environmentally friendly emission standards.
[0004] However, the aforementioned patent requires an external power source to drive a multi-stage hydraulic cylinder to push the telescopic cylinder to unfold, which increases the difficulty of installation and the intensity of manual pulling, is time-consuming and labor-intensive, and seriously affects the efficiency of the chimney telescopic operation. Therefore, a new device needs to be designed. Utility Model Content

[0026] Please see Figures 1-8 A retractable chimney device includes an end cap 4 and a fixing rope 5, and also includes a body assembly 1 for nesting and retracting. A smoke cap assembly 2 for dispersing smoke is installed at the top of the body assembly 1, and a lifting assembly 3 for inflating and floating is installed at the top of the smoke cap assembly 2. When stored, the end cap 4 is fastened to the end face of the lifting assembly 3, and the smoke cap assembly 2 and the body assembly 1 are tied and fixed by the fixing rope 5.
[0027] In this embodiment: the main body assembly 1 includes a rigid base 101 and several flexible telescopic bodies 102. The flexible telescopic bodies 102 are nested together from the inside out, with the rigid base 101 wrapped around the outermost part. Upper limit rings 106 of corresponding sizes are respectively provided at the top of the rigid base 101 and the flexible telescopic bodies 102, and lower limit rings 105 of corresponding sizes are respectively provided at the bottom of the flexible telescopic bodies 102. A connecting flange 103 is provided at the bottom of the rigid base 101, and a fixing hook 104 is provided on the outer side of the top of the rigid base 101. Both the rigid base 101 and the flexible telescopic bodies 102 are tapered, and the flexible telescopic bodies 102 are riveted to the upper limit ring 106 and the lower limit ring 105 respectively. Two fixing hooks 104 are symmetrically arranged and welded to both sides of the rigid base 101. During installation, the connecting flange... 103 The rigid base 101 is fixed at the smoke-generating position. The smoke exhaust cap 201 pulls the uppermost flexible telescopic body 102 upward through the upper limit ring 106. The lower limit ring 105 at the bottom of the uppermost flexible telescopic body 102 pulls the second layer of flexible telescopic body 102 upward through the upper limit ring 106 of the second layer, and so on, until all flexible telescopic bodies 102 are extended and finally fixed by the upper limit ring 106 of the rigid base 101. When exhausting smoke, the smoke enters from the bottom of the rigid base 101 and rises along the flexible telescopic bodies 102 in sequence. When storing, the flexible telescopic bodies 102 are nested inside the rigid base 101 from the inside out, and the smoke exhaust cap 201 and the fixing hook 104 are tied together with the fixing rope 5. When maintaining or replacing, the flexible telescopic bodies 102 are pulled out from the bottom of the rigid base 101 in sequence for maintenance and replacement.
[0028] In this embodiment: the cigarette cap assembly 2 includes a smoke exhaust cap 201, with a smoke passage hole 204 in the middle of the smoke exhaust cap 201, and several smoke outlet holes 202 evenly distributed around the circumference of the smoke exhaust cap 201. A positioning mechanism for storage and connection is provided on the top surface of the smoke exhaust cap 201. The positioning mechanism includes a positioning ring 205 and a magnetic ring 206 on the bottom surface of the smoke exhaust cap 201, with the magnetic ring 206 positioned around the outer ring of the positioning ring 205. The smoke exhaust cap 201 is a cylindrical shape with an open top, and is bolted to the upper limit ring 106 of the uppermost flexible telescopic body 102. During smoke exhaust, the smoke passes through the smoke passage hole 204 into the smoke exhaust cap 201 and finally exits from the smoke outlet holes 202. During storage, first... Pull the fixing rope 5 to pull down the smoke exhaust cap 201. The positioning ring 205 on the bottom surface of the smoke exhaust cap 201 is inserted into the upper limit ring 106 of the rigid base 101 for positioning. At the same time, the magnetic ring 206 on the bottom surface of the smoke exhaust cap 201 attracts the upper limit ring 106 of the rigid base 101 for fixation. The smoke exhaust cap 201 and the fixing hook 104 are tied together with the fixing rope 5 for fixation. When repairing or replacing, first rotate the connecting seat 301 to separate the external thread 303 at the bottom of the connecting seat 301 from the internal thread 203 at the top of the smoke exhaust cap 201. Then remove the bolt inside the smoke exhaust cap 201 that connects to the upper limit ring 106 of the uppermost flexible telescopic body 102 to separate the smoke exhaust cap 201 from the flexible telescopic body 102.
[0029] In this embodiment: the lifting component 3 includes a connecting seat 301, a receiving cavity 302 is provided inside the connecting seat 301, an airbag ball 304 is attached to the bottom surface of the receiving cavity 302, an inlet / outlet pipe 305 is installed on the top of the airbag ball 304, and an inlet / outlet valve 306 is installed on the inlet / outlet pipe 305. The lifting component 3 and the smoke cap component 2 are connected by a threaded mechanism; the threaded mechanism includes an internal thread 203 provided on the top of the smoke cap 201 and an external thread 303 provided on the bottom of the connecting seat 301, the internal thread 203 and the external thread 303 adopt a fine thread structure; the connecting seat 301 is made of heat insulation material; during installation... Open the inlet / outlet valve 306 and fill the airbag ball 304 in the storage cavity 302 with helium through the inlet / outlet pipe 305. This causes the airbag ball 304 to expand and generate buoyancy, which pulls the exhaust cap 201 to float into the air through the connecting seat 301. When storing, open the inlet / outlet valve 306 and expel the helium in the airbag ball 304 through the inlet / outlet pipe 305. Insert the airbag ball 304 into the storage cavity 302 of the connecting seat 301. Finally, put on the end cover 4. When maintaining or replacing, rotate the connecting seat 301 to separate the external thread 303 at the bottom of the connecting seat 301 from the internal thread 203 at the top of the exhaust cap 201.
[0030] Working principle: During installation, first fix the rigid base 101 to the smoke-generating position through the connecting flange 103, then open the end cover 4, untie the fixing rope 5, and then open the inlet and outlet valve 306. Helium is filled into the airbag ball 304 in the storage cavity 302 through the inlet and outlet pipe 305, causing the airbag ball 304 to expand and generate buoyancy. The connecting seat 301 pulls the smoke cap 201 to float and rise into the air. The smoke cap 201 then pulls the uppermost flexible telescopic body 102 to rise through the upper limit ring 106. The lower limit ring 105 at the bottom of the uppermost flexible telescopic body 102 pulls the second layer of flexible telescopic body 102 to rise through the upper limit ring 106 of the second layer, and so on, until all the flexible telescopic bodies 102 are extended and finally fixed by the upper limit ring 106 of the rigid base 101. Then, the fixing rope 5 passing through the smoke outlet hole 202 on the smoke cap 201 is tied to the fixing hook 104 for fixation.
[0031] During smoke exhaust, the smoke enters from the bottom of the rigid base 101, rises along the flexible telescopic body 102, until it passes through the smoke passage 204 and enters the smoke exhaust cap 201, and finally exits from the smoke outlet 202.
[0032] When storing, first pull the fixing rope 5 to pull down the smoke exhaust cap 201. The positioning ring 205 on the bottom surface of the smoke exhaust cap 201 is inserted into the upper limit ring 106 of the rigid base 101 for positioning. At the same time, the magnetic ring 206 on the bottom surface of the smoke exhaust cap 201 attracts the upper limit ring 106 of the rigid base 101 for fixation, so that the flexible telescopic body 102 is nested inside the rigid base 101 from the inside out. Then, use the fixing rope 5 to tie the smoke exhaust cap 201 and the fixing hook 104 for fixation. Next, open the air inlet and outlet valve 306 to discharge the helium in the airbag ball 304 through the air inlet and outlet pipe 305. Insert the airbag ball 304 into the storage cavity 302 of the connecting seat 301. Finally, put on the end cap 4.
[0033] During maintenance and replacement, first rotate the connecting seat 301 to separate the external thread 303 at the bottom of the connecting seat 301 from the internal thread 203 at the top of the smoke exhaust cap 201. Then remove the bolts inside the smoke exhaust cap 201 that connect to the upper limit ring 106 of the uppermost flexible telescopic body 102 to separate the smoke exhaust cap 201 from the flexible telescopic body 102. Then, pull out the flexible telescopic bodies 102 one by one from the bottom of the rigid base 101 for maintenance and replacement.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
