Description

Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, and specifically to a composite aluminum magnesium silicate ventilation duct. Background Art

[0002] Ventilation ducts are metal or non-metallic pipes used in ventilation and air conditioning engineering in industrial and civil buildings. They are a kind of municipal infrastructure to allow air circulation and reduce the concentration of harmful gases. The plates, profiles and other main finished materials used in the production and installation of ducts should comply with the design and relevant national standards for products, and should be accompanied by factory inspection certificates. When materials are delivered to the site, they should be inspected and accepted according to the relevant national standards.

[0003] In the prior art, the utility model with the authorization announcement number CN209909329U is named as: an aluminum-magnesium fire-resistant heat-insulating ventilation duct, comprising a rectangular tube and an aluminum-magnesium fire-resistant board, wherein the rectangular tube is a metal tube, and the four sides of the rectangular tube are covered with aluminum-magnesium fire-resistant boards, and a layer of fire-resistant adhesive is provided between the rectangular tube and the aluminum-magnesium fire-resistant board, and between adjacent aluminum-magnesium fire-resistant boards; the outer surface of the ventilation duct is sleeved with a plurality of strong clamps along the direction of the duct. It can meet the fire resistance limit requirements specified in national standards and has good construction performance.

[0004] However, in order to remove dust from the air, filters and filter cotton are generally installed inside the ventilation duct through bolts to deal with the dust in the air. After long-term use, it needs to be cleaned. Since the bolts are fixed inside the duct, the filter needs to be removed with a screwdriver, which is time-consuming and labor-intensive, and is not conducive to cleaning personnel quickly removing the dust filter for cleaning.

[0005] In the prior art, the utility model with authorization announcement number CN211753357U is named: workshop exhaust gas treatment ventilation pipe. Through the structural coordination of a mounting seat, a handle, a fixing seat, a fastening bolt, a filter screen, filter cotton and an activated carbon filter screen, the exhaust gas flowing through the first pipe and the second pipe can be fully filtered for particles to prevent the exhaust gas from carrying dust particles to pollute the surrounding environment, thereby improving the air quality around the workshop and avoiding exhaust gas pollution from causing harm to the health of surrounding residents.

[0006] However, the installation and removal of the filter screen in the above device both need to be achieved by screwing the bolts with a screwdriver, which is troublesome to install and remove, and is not conducive to the staff's regular maintenance of the filter screen. Utility Model Content

[0010] Furthermore, one end of the four telescopic springs is fixedly connected to the outer surfaces of the four round blocks, and the other ends of the four telescopic springs are fixedly connected to the four surfaces of the mounting seat. By limiting the positional relationship of the telescopic springs, the state of the limit block can be conveniently limited.

[0011] Furthermore, a handle is fixedly connected to the outer surface of each of the round blocks, and an anti-slip layer is coated on the outer surface of each of the handles. By providing a handle, the contact area of ​​the round block can be increased, making it easier to pull the limit block.

[0012] Furthermore, the size value of the activated carbon filter corresponds to the size value of the inner wall of the mounting base, and the four limit blocks respectively correspond to the positions and sizes of the four limit grooves.

[0014] Furthermore, the other end of the flame retardant layer is fixedly connected with four connection blocks, and the connection blocks can be conveniently provided for connection with other ventilation ducts.

[0015] Furthermore, two positioning frames are fixedly connected to the outer surface of the flame retardant layer, and a positioning block is fixedly connected to the top of each positioning frame. By arranging the positioning frames and the positioning blocks, the pipeline can be suspended and installed on the beam.

[0016] The working principle and beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 to Figure 4 As shown, this embodiment proposes a composite magnesium aluminum silicate ventilation duct, including a composite duct 1 and a clamping mechanism 3 , wherein the interior of the composite duct 1 includes a magnesium aluminum silicate layer 101 , a sound insulation layer 102 and a flame retardant layer 103 .

[0027] The sound insulation layer 102 is bonded to the outer surface of the magnesium aluminum silicate layer 101, and the flame retardant layer 103 is fixedly connected to the outer surface of the sound insulation layer 102 by inlaying. By limiting the connection relationship between the magnesium aluminum silicate layer 101, the sound insulation layer 102 and the flame retardant layer 103, the pipeline can have good flame retardant and sound insulation effects.

[0028] The flame retardant layer 103 is located at the outermost layer, which can make the pipeline have a good flame retardant effect, and the sound insulation layer 102 is located at the middle layer, which can reduce the generation of noise.

[0029] An activated carbon filter 2 is installed at one end of the flame retardant layer 103, and the activated carbon filter 2 is clamped to one end of the flame retardant layer 103 through a clamping mechanism 3. The activated carbon filter 2 can fully filter the gas output by the pipeline to prevent the discharged gas from carrying dust particles and polluting the surrounding environment.

[0030] The clamping mechanism 3 includes a mounting seat 301 fixedly connected to the outer surface of the flame retardant layer 103, the inner wall sliding sleeve of the mounting seat 301 is provided with four limit blocks 302, the outer surface of each limit block 302 is fixedly connected to a round block 303, and the outer sleeve of each limit block 302 is provided with a telescopic spring 304.

[0031] One end of the four telescopic springs 304 is fixedly connected to the outer surfaces of the four round blocks 303, and the other ends of the four telescopic springs 304 are fixedly connected to the four surfaces of the mounting seat 301. By limiting the position relationship of the telescopic springs 304, the state of the limit block 302 can be conveniently limited.

[0032] When the round block 303 is pulled outward, the limit block 302 can be moved outward, thereby stretching the telescopic spring 304, which deforms and generates elastic force. When the pulled round block 303 is released, the limit block 302 is reset with the help of the elastic force generated by the telescopic spring 304, and can be reset to Figure 2 Status shown.

[0033] Limiting grooves 306 are provided on the four surfaces of the activated carbon filter 2. The size of the activated carbon filter 2 corresponds to the size of the inner wall of the mounting seat 301. The four limiting blocks 302 correspond to the positions and sizes of the four limiting grooves 306 respectively. The activated carbon filter 2 can be inserted into the inner wall of the mounting seat 301, and the limiting blocks 302 can be inserted into the inner wall of the limiting grooves 306.

[0034] The activated carbon filter 2 can be disassembled by pulling the four round blocks 303 outward. When the four round blocks 303 are pulled outward, the four limit blocks 302 will be moved out of the corresponding limit grooves 306 respectively. This can release the limiting work on the activated carbon filter 2. The staff can directly remove the activated carbon filter 2 from one end of the flame retardant layer 103, which is convenient for the staff to regularly clean and maintain the activated carbon filter 2.

[0035] Furthermore, when disassembling and assembling the activated carbon filter 2 , it is no longer necessary to use additional tools such as a screwdriver, thereby effectively optimizing the disassembly and assembly work of the activated carbon filter 2 .

[0036] Example 2

[0037] like Figure 1 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the outer surface of each round block 303 is fixedly connected with a handle 305, and the outer surface of each handle 305 is coated with an anti-slip layer. By setting the handle 305, the contact area of ​​the round block 303 can be increased, which facilitates the pulling of the limit block 302, thereby facilitating the disassembly and assembly of the activated carbon filter 2.

[0038] A sealing ring 307 is fixedly connected to the back of the activated carbon filter 2, and the sealing ring 307 is compatible with the mounting seat 301. By providing the sealing ring 307, the sealing performance of the activated carbon filter 2 during installation can be improved, the filtering effect of the activated carbon filter 2 can be improved, and environmental pollution can be avoided.

[0039] The other end of the flame retardant layer 103 is fixedly connected with four connection blocks 4. The connection blocks 4 can be conveniently connected to other ventilation ducts, thereby improving the convenience of installing the duct.

[0040] Two positioning frames 5 are fixedly connected to the outer surface of the flame retardant layer 103 , and a positioning block 6 is fixedly connected to the top of each positioning frame 5 . By arranging the positioning frames 5 and the positioning blocks 6 , the pipeline can be suspended and installed on the beam.

[0041] Working principle: when the activated carbon filter 2 needs to be disassembled, the four handles 305 can be pulled outwards, at which time the four limit blocks 302 will move outwards respectively, and the four telescopic springs 304 will be in a stretched state, and at the same time, the four limit blocks 302 will be moved out of the corresponding limit grooves 306 respectively, and then the staff can directly disassemble the activated carbon filter 2 from the mounting seat 301 for cleaning and maintenance, and then reinsert the maintained activated carbon filter 2 into the mounting seat 301. During the insertion process, the surface of the activated carbon filter 2 will be released to the corresponding limit blocks 302 respectively, and the four limit blocks 302 will be moved outwards. When the activated carbon filter 2 is fully inserted into the mounting seat 301, the four limit blocks 302 will respectively rebound with the elastic force generated by the deformation of the corresponding limit springs 304, and the four limit blocks 302 will respectively rebound into the corresponding limit grooves 306, completing the work of quickly installing the activated carbon filter 2 on one end of the flame retardant layer 103, which is convenient for filtering the gas discharged from the pipeline and reducing pollution to the environment. Finally, the flame retardant effect of the pipeline can be improved by the outermost flame retardant layer 103, and the noise generated during ventilation can be reduced by the sound insulation layer 102, which is more practical.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
