Description

Technical Field

[0001] The utility model relates to the technical field of air duct connection in clean engineering, in particular to a fully sealed air duct connection and a finished product protection device used in clean engineering. Background Art

[0002] The ventilation system of clean engineering may involve toxic and harmful gases, bacteria, viruses, odors, etc., and the requirements for air leakage and cleanliness of air ducts are higher than those of general engineering. The traditional method of connecting air ducts is to pad the cross-section of the air duct interface with strip-shaped sealing strips. Although this method is feasible, there will be gaps at the beginning and end of the sealing strip, and the thickness of the padding at the corners will be less than that of other places due to the stretching of the padding, which is easy to cause leakage. Therefore, this method of connecting air ducts with padding and sealing strips is not conducive to the formation of a clean environment and is difficult to meet the needs of clean engineering.

[0003] On the other hand, traditional duct connections generally process a single section of duct in the processing area and then transport it to the site for installation and connection. Clean engineering has high requirements for the cleanliness of ducts, and the processing area should be clean and dust-free. After the duct processing is completed, the two ends must be covered with plastic film and transported to the site for installation and connection. After the installation is completed, the duct openings are covered with plastic film again. Therefore, clean duct construction should minimize the construction content and duration of the construction site, and most of the prefabrication work should be arranged in a relatively clean processing area. However, the thickness and strength of the duct material are generally low, and the length and mass after prefabrication are large. Stress concentration is prone to occur during transportation, which destroys the tightness of the duct connection structure. Utility Model Content

[0009] Preferably, one end of the hook 1 is connected to the screw 1, and the other end of the rod is connected to the screw 2. Both ends of the tightener are internally threaded, and the rod and the hook 1 are connected by the internal threads at both ends of the tightener.

[0010] Preferably, the angle steel flange comprises a combined flange strip and an angle connector which are connected to each other, and the connection between the combined flange strip and the angle connector is sealed by a second sealant.

[0011] Preferably, the angle steel flange is connected to the end of the air duct through rivets, and the distance between the angle steel flange and the fixed rivets is no more than 150 mm.

[0012] Preferably, a sealant is coated at the joint between the air duct and the rivet.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example

[0028] like Figures 1 to 6 As shown, a fully sealed air duct connection device and a finished product protection device for clean engineering provided by the utility model is used to connect multiple air ducts 1, including an air duct sealing connection part, which is used to connect multiple air ducts 1;

[0029] The air duct sealing connection part includes an angle steel flange 3 and a finished sealing ring 2. The angle steel flange 3 includes a combined flange strip 31 and an angle connector 32 connected to each other. The connection between the combined flange strip 31 and the angle connector 32 is sealed by a sealant 33.

[0030] The angle steel flange 3 is arranged at the opening position of the ends of the plurality of air ducts 1 and connected to the ends of the air ducts 1 through rivets 4. The distance between the angle steel flange 3 and the fixed rivets 4 is not greater than 150 mm.

[0031] The finished sealing ring 2 is integrally formed, and the size of the finished sealing ring 2 needs to match the opening diameter of the air duct 1. The finished sealing ring 2 is arranged between the angle steel flanges 3 of the adjacent air ducts 1 and connected by a locking mechanism, which includes a bolt 6 and a nut 7. The bolt 6 passes through one angle steel flange 3, the finished sealing ring 2 and another angle steel flange 3 in sequence, and the three components are locked by the nut 7.

[0032] The two air ducts 1 are connected by the finished product protection device 8 to form an air duct group; at least two groups of finished product protection devices 8 are provided, and the two groups of finished product protection devices 8 are staggered and arranged on opposite sides of the air duct group. The staggered installation of the finished product protection devices 8 can facilitate the stacking of the air duct group during transportation and storage, and also make it easier to leave the central axis position of the air duct for workers to carry.

[0033] The finished product protection device 8 includes a hook 81, a tightener 82 and a rod 83; one end of the hook 81 is connected to a screw 1; one end of the rod 83 is provided with a hook 2, and the hook 2 has the same structure as the hook 81. The hook 2 and the hook 81 are respectively hooked on the openings at both ends of the air duct group, and the other end of the rod 83 is connected to the screw 2. The two ends of the tightener 82 are internally threaded, and the internal threads at both ends of the tightener 82 are used to connect the rod 83 and the hook 81, so as to reduce the problem of stress concentration between the two air ducts 1 during transportation, thereby destroying the tightness of the structure after the air duct group is connected.

[0034] An air duct 1, a specially manufactured sealing ring 2 and a finished protective device 8. The specially manufactured sealing ring 2 is customized according to the size of the air duct 1, has no gaps as a whole and has uniform thickness. The gasket is placed between two angle steel flanges 3. The two angle steel flanges 3 are respectively located at the connection between the two sections of the air duct 1 and are fixed to the air duct 1 with rivets 4. The rivets 4 are sealed with sealant. The two angle steel flanges 3 are connected and fixed with bolts 6 and nuts 7.

[0035] The working principle of the present invention is as follows:

[0036] Step S1: After connecting the combined flange strip 31 and the angle connector 32, a sealing member 2 33 is applied at the connection to form an L-shaped angle steel flange 3;

[0037] Step S2: fix the L-shaped angle steel flange 3 to the opening at the end of the air duct 1 by using the rivet 4, and seal the joint between the air duct 1 and the rivet 4 by using the sealant 5.

[0038] Step S3: Place the finished sealing ring 2 customized according to the size of the air duct 1 between the angle steel flanges 3 pre-installed on the two air ducts 1, and use bolts 6 and nuts 7 to connect and fix the angle steel flanges 3 pre-installed on the two air ducts 1 with the finished sealing ring 2 therebetween, thereby completing the air duct prefabrication process;

[0039] Step S4: hook the hook 1 81 of the finished product protection device 8 onto the open end of one air duct 1 in the air duct group, and hook the hook 2 84 on the rod 83 onto the open end of another air duct 1 in the air duct group;

[0040] Step S5: After the hooks at both ends of the air duct assembly are completed, the tightener 82 is rotated, and the two ends of the tightener 82 are fixedly connected to the rod body 83 and the hook 1 81 through threads.

[0041] The above are two sections of air ducts prefabricated in the clean processing area. After prefabrication, the finished product protection device is installed. The processed air duct group is transported to the construction site for installation and connection. In actual use, the finished product protection device can also be installed after prefabrication in an off-site prefabrication factory, and then directly transported to the construction site for installation.

[0042] This embodiment takes a rectangular air duct as an example. In actual use, other structural forms including but not limited to round steel, angle steel, flat steel, etc. can be used.

[0043] Functions and effects in the embodiments:

[0044] This embodiment uses an integrally formed finished sealing ring to replace the traditional strip sealing strip. Its size is customized according to the opening diameter of the air duct. The whole is seamless and has uniform thickness. Compared with the traditional strip sealing strip, the finished sealing ring does not have a gap at the beginning and end connection, and will not be stretched at the corners to cause uneven thickness. The air duct connected by the utility model has significantly reduced the number of gaps and air leakage, which can better meet the use requirements of clean engineering and is more conducive to forming a clean environment.

[0045] In this embodiment, a finished product protection device is installed on the opposite side of the air duct to solve the problem of stress concentration during the transportation of the prefabricated air duct and damage to the tightness of the air duct connection structure. The assembly and connection of two or more sections of air ducts can be completed in the clean processing area, reducing the construction content and duration at the construction site, reducing the possibility of air duct contamination, meeting the use requirements of clean engineering, and facilitating the formation of a clean environment.

[0046] In this embodiment, the finished product protection devices installed on the opposite sides can also be stacked up and down during transportation and storage through the staggered arrangement of the finished product protection devices, leaving space for workers to use the central axis of the air duct to carry the products.
