Description

Technical Field

[0001] This utility model relates to the field of stainless steel duct technology, specifically to a stainless steel duct that is easy to clean. Background Technology

[0002] Air ducts are piping systems used for air transport and distribution. There are two types: composite air ducts and inorganic air ducts. They can be classified according to cross-sectional shape and material. Stainless steel air duct manufacturing involves applying sealant to gaps such as seams, rivet seams, and the four corners of flanges.

[0003] The utility model patent with announcement number CN213655944U discloses a circulating water-cooled ventilation pipe that is easy to clean, including a ventilation pipe and an installation ring. The installation ring is sleeved on the outside of the ventilation pipe, and pre-installed rings are welded to both ends of the outside of the ventilation pipe. An installation flange is provided on the outside of the pre-installed ring, and the installation flange is connected to the pre-installed ring by fastening bolts.

[0004] However, the above technical solution still has some shortcomings: when using the above technical solution, it is necessary to remove the bolts and then remove the flange to clean the inside of the air duct. In actual use, the cleaning is relatively cumbersome and not easy to achieve a good cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide a stainless steel duct that is easy to clean, in order to solve the problem mentioned in the background art that the method of cleaning the inside of the duct by disassembling the flange is not convenient enough.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel air duct that is easy to clean, comprising an air duct body,

[0007] The bottom of the duct body is provided with an installation port, and an installation plate is installed at the installation port by bolts. An installation frame is fixedly installed on the top of the installation plate, and a filter screen is installed inside the installation frame.

[0008] A lifting groove is provided on the front side wall of the air duct body, and a lifting and lowering sealing baffle is installed in the lifting groove. A sliding push rod is slidably installed in the lifting groove, and the end of the sliding push rod is inserted into the air duct body and connected to the scraper frame. The outer side of the scraper frame is tightly fitted to the inner side wall of the air duct body.

[0009] By adopting the above technical solution, when it is necessary to clean the inner wall of the duct body, the mounting plate is disassembled, and the mounting frame and filter screen are moved down to facilitate the cleaning of the filter screen. Then, the sealing baffle is pushed up so that the sliding push rod can slide in the lifting groove. The sliding push rod drives the scraper frame to move laterally in the duct body, which can scrape the inner wall of the duct body and push the dust towards the installation port, achieving a rapid cleaning effect.

[0010] As a further embodiment of this utility model: the bottom of the duct body is provided with a connecting threaded port located outside the mounting port.

[0011] By adopting the above technical solution, the threaded connection can be threaded to the air inlet of an external negative pressure fan during use, which facilitates the connection of the negative pressure fan at the installation port, thereby attracting dust from the installation port and leaving the duct body, achieving a rapid cleaning effect.

[0012] As a further embodiment of this utility model: the end of the duct body is provided with a connecting flange, and two sets of scraper frames and sliding push rods are provided, with the scraper frames and sliding push rods installed on the side close to the connecting flange.

[0013] By adopting the above technical solution, the design of the connecting flange facilitates docking with external mechanisms during use, and the design of two sets of scraper frames and sliding push rods can achieve secondary cleaning, preventing the dust scraped off in the first scraping from falling to the side of the scraper frame and becoming impossible to clean, thus improving the cleaning effect.

[0014] As a further embodiment of this utility model: a pull handle is installed on the front side of the sealing baffle, and a notch is opened on the upper side wall of the middle part of the lifting groove, and the notch is aligned with the pull handle.

[0015] By adopting the above technical solution, the design of the handrail facilitates the raising and lowering of the sealing baffle during use, and the notch design makes it easy to store the handrail.

[0016] As a further embodiment of this utility model: a magnet is installed in the notch opened on the lifting groove, and the pull handle is made of magnetic metal.

[0017] By adopting the above technical solution, the design of the magnet facilitates the attraction with the pull handle during use, thereby avoiding the sealing baffle from applying pressure to the top of the sliding push rod when it moves laterally, which would otherwise obstruct the sliding motion.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the stainless steel air duct is easy to clean.

[0019] Equipped with a mounting frame, filter screen, scraper frame, and sliding push rod, the ductwork can be cleaned by removing the mounting plate, mounting frame, and filter screen, then pulling up the sealing baffle, and using the sliding push rod to move the scraper frame horizontally. This scrapes away the dust on the inner wall and pushes it towards the filter screen's installation position, effectively cleaning the inner wall of the ductwork. Attached Figure Description

[0025] See also Figure 1-3 This utility model provides a technical solution: an easy-to-clean stainless steel air duct, including an air duct body 1.

[0026] The bottom of the duct body 1 is provided with an installation port, and an installation plate 2 is installed at the installation port by bolts. An installation frame 3 is fixedly installed on the top of the installation plate 2, and a filter screen 4 is installed inside the installation frame 3.

[0027] A lifting groove 101 is provided on the front side wall of the duct body 1, and a lifting sealing baffle 7 is installed in the lifting groove 101. A sliding push rod 9 is slidably installed in the lifting groove 101, and the end of the sliding push rod 9 is inserted into the duct body 1 and connected to the scraper frame 6. The outer side of the scraper frame 6 is tightly fitted to the inner side wall of the duct body 1.

[0028] See also Figure 1 and Figure 2 Furthermore, a connecting threaded port 10 is installed at the bottom of the duct body 1 on the outside of the mounting port;

[0029] Specifically, a filter box should be connected to the air inlet pipe of the external negative pressure fan to facilitate the collection and filtration of attracted dust.

[0030] See also Figure 1 and Figure 2 Furthermore, the end of the duct body 1 is provided with a connecting flange 5, and two sets of scraper frame 6 and sliding push rod 9 are provided, with the scraper frame 6 and sliding push rod 9 installed on the side close to the connecting flange 5.

[0031] See also Figure 1 and Figure 3Furthermore, a pull handle 701 is installed on the front side of the sealing baffle 7, and a notch is opened on the upper side wall of the middle part of the lifting groove 101, and the notch is aligned with the pull handle 701.

[0032] See also Figure 1 Furthermore, a magnet 8 is installed in the notch opened on the lifting groove 101, and the handrail 701 is made of magnetic metal.

[0033] Working principle: When using this easy-to-clean stainless steel duct, the mounting plate 2 is removed, and the mounting frame 3 and filter screen 4 are moved down to facilitate cleaning of the filter screen 4. Then, the duct body 1 is connected to the air inlet pipe of the external negative pressure fan through the connecting threaded port 10. Then, the sealing baffle 7 is pushed upward, so that the sliding push rod 9 can slide in the lifting groove 101.
