Description

Technical Field

[0001] This application relates to the field of exhaust duct technology, and in particular to an exhaust duct structure. Background Technology

[0002] Ventilation ducts are a type of municipal infrastructure used to circulate air and reduce the concentration of harmful gases. Ventilation ducts are generally classified by material as follows: steel plate ducts, galvanized steel plate ducts, stainless steel ventilation ducts, fiberglass ventilation ducts, plastic ventilation ducts, composite material ventilation ducts, color steel sandwich insulation board ventilation ducts, double-sided aluminum foil insulation ventilation ducts, single-sided color steel insulation ventilation ducts, coated cloth ventilation ducts, and mining plastic ventilation ducts.

[0003] Existing exhaust ducts cannot seal the inside of the duct in a timely manner when cleaning and maintaining it, which leads to continuous airflow through the duct during maintenance, which seriously affects the efficiency of maintenance and can also interfere with the clarity of the view for the staff. Therefore, this application proposes an exhaust duct structure. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an exhaust pipe structure that overcomes the deficiencies of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: an exhaust pipe structure, including a pipe, a frame fixedly installed on the top of the pipe, a rotating disk rotatably connected to the top of the frame, a rotating rod fixedly installed on the inner wall of the rotating disk, a wind baffle plate installed on the outer side of the rotating rod by three screws, a sealing ring fixedly installed on the outer edge of the wind baffle plate, a fixing disk fixedly installed on the inner wall of the pipe, a filter screen abutting against the outer wall of the fixing disk, and an abutting disk abutting against the outer wall of the filter screen.

[0006] In a preferred embodiment, bearing two and bearing one are installed on both the upper and lower sides of the inner wall of the pipe, and the rotating rod is installed on the inner wall of bearing two and bearing one.

[0007] By adopting the above technical solution, the rotating rod can be limited during rotation, ensuring its stability during rotation and preventing it from easily detaching from the inner wall of the pipe. It also ensures that the baffle plate and sealing ring can rotate stably inside the pipe.

[0008] In a preferred embodiment, the inner wall of the rotating disk has a slot, a gasket is installed on the top of the frame, a bolt is threaded onto the inner wall of the gasket, the bottom of the bolt nut abuts against the top of the rotating disk, and the bolt shank is inserted into the inner wall of the rotating disk.

[0009] By adopting the above technical solution, the rotatable disc drives the rotating rod to adjust the angle of the wind deflector. At the same time, the disc can be locked with bolts to ensure that it will not rotate easily.

[0010] In a preferred embodiment, a handle is fixedly installed on the side of the rotating disk away from the slot opening.

[0011] By adopting the above technical solution, it is easy for users to adjust the position of the wind deflector by turning the rotating disc with their hands.

[0012] In a preferred embodiment, a pressure relief pipe is installed on the inner wall of the pipe.

[0013] By adopting the above technical solution, when the gas pressure inside the pipeline is accidentally blocked and becomes too high, the internal pressure of the pipeline can be temporarily relieved, and a solenoid valve can be installed inside the pressure relief pipe to achieve precise control.

[0014] In a preferred embodiment, three magnetic rods are fixedly installed on the side of the abutment plate near the filter screen. The inner wall of the filter screen has three insertion holes, and the three magnetic rods are inserted into the inner walls of the three insertion holes. The end of the magnetic rod away from the abutment plate is attached to the fixed plate, which is made of magnetic material.

[0015] By adopting the above technical solution, the magnetic attraction principle can be used to stably connect the receiving plate and the fixed plate, thereby positioning the filter screen installed between the fixed plate and the receiving plate, ensuring the stability of the filter screen installed inside the pipe, and ensuring that it will not easily shift its position when blown by wind.

[0016] In a preferred embodiment, a mounting bracket is installed on the inner wall of the pipe, and a temperature sensor and an anemometer are installed on the outer wall of the mounting bracket.

[0017] By adopting the above technical solution, it becomes possible to monitor the temperature and airflow of the gas flowing inside the pipeline.

[0018] In a preferred embodiment, the outer diameter of the sealing ring is adapted to the inner diameter of the pipe, and the sealing ring is made of rubber.

[0019] By adopting the above technical solution, the sealing performance when the outside of the baffle plate comes into contact with the inside of the pipe can be guaranteed, and when the baffle plate is in the closed state, no gas will leak through the connection between the baffle plate and the inner wall of the pipe.

[0020] In a preferred embodiment, the outer diameter of the filter screen is adapted to the inner diameter of the pipe.

[0021] By adopting the above technical solution, it is ensured that all gas flowing inside the pipeline must be filtered through the filter screen before it can flow to the side of the filter screen away from the baffle plate, thus ensuring the comprehensiveness of filtration.

[0022] In a preferred embodiment, the outer edge of the pipe is uniformly coated with a galvanized layer.

[0023] By adopting the above technical solutions, it can be ensured that the pipeline will not be easily corroded after being exposed to air and rainwater, thus ensuring its service life.

[0024] The beneficial effects of this application are:

[0025] This type of exhaust duct structure allows the rotating handle to drive the rotating disc, which in turn pushes the rotating rod to rotate the baffle plate inside the duct. This can be used to regulate the airflow inside the duct, and the outer edge of the rotating sealing ring can be made to fit against the inner wall of the duct to ensure airtightness. This ensures the efficiency of users when maintaining the inside of the duct and will not affect the user's eyes.

[0026] This type of exhaust pipe structure allows the abutment plate to be removed by eliminating the magnetism of the magnetic rod, and then the magnetic rod can be taken out from the inner wall of the socket to remove the filter screen, thus facilitating the maintenance and replacement of the filter screen.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] Reference Figure 1-5 A ventilation duct structure includes a duct 1, a frame 2 fixedly installed on the top of the duct 1, a rotating disk 3 rotatably connected to the top of the frame 2, a rotating rod 8 fixedly installed on the inner wall of the rotating disk 3, a baffle plate 9 installed on the outer side of the rotating rod 8 by three screws 10, a sealing ring 11 fixedly installed on the outer edge of the baffle plate 9, a fixing disk 15 fixedly installed on the inner wall of the duct 1, a filter screen 17 abutting against the outer wall of the fixing disk 15, and an abutting disk 16 abutting against the outer wall of the filter screen 17.

[0035] See Figure 2 Bearing 2 13 and bearing 12 are installed on both the upper and lower sides of the inner wall of pipe 1. The rotating rod 8 is installed on the inner wall of bearing 2 13 and bearing 12, so that it can be used to limit the rotating rod 8 when rotating, ensuring the stability of the rotating rod 8 when rotating, ensuring that it will not easily detach from the inner wall of pipe 1 when rotating, and ensuring that the baffle plate 9 and the sealing ring 11 can rotate stably inside pipe 1.

[0036] See Figure 3 The inner wall of the rotating disk 3 has a slot 5, and a gasket 6 is installed on the top of the frame 2. The inner wall of the gasket 6 is threaded with a bolt 7. The bottom of the nut of the bolt 7 abuts against the top of the rotating disk 3, and the screw of the bolt 7 is inserted into the inner wall of the rotating disk 3, so that the rotating disk 3 can drive the rotating rod 8 to rotate and adjust the angle of the wind deflector 9. At the same time, the bolt 7 can be used to lock the rotating disk 3 to ensure that it will not rotate easily.

[0037] See Figure 2 and Figure 3 A handle 4 is fixedly installed on the side of the rotating disk 3 away from the slot 5, making it convenient for the user to rotate the rotating disk 3 to adjust the position of the wind deflector 9.

[0038] See Figure 1 and Figure 2 The inner wall of pipe 1 is equipped with a pressure relief pipe 14, which allows for temporary pressure relief when the internal pressure of pipe 1 is accidentally blocked and too high. Furthermore, a solenoid valve can be installed inside the pressure relief pipe 14 for precise control.

[0039] See Figure 4 and Figure 5Three magnetic rods 19 are fixedly installed on the side of the receiving plate 16 near the filter screen 17. The inner wall of the filter screen 17 has three insertion holes 18, and the three magnetic rods 19 are inserted into the inner wall of the three insertion holes 18. The end of the magnetic rod 19 away from the receiving plate 16 is attached to the fixing plate 15. The fixing plate 15 is made of magnetic material, so that the receiving plate 16 and the fixing plate 15 can be stably attracted and connected by magnetic attraction. This is used to position the filter screen 17 installed in the middle of the fixing plate 15 and the receiving plate 16, ensuring the stability of the filter screen 17 installed inside the pipe 1 and ensuring that it will not easily shift its position when blown by the wind.

[0040] See Figure 2 A mounting bracket 20 is installed on the inner wall of the pipe 1, and a temperature sensor 21 and an air velocity flow meter 22 are installed on the outer wall of the mounting bracket 20, so that they can be used to monitor the temperature and air volume of the gas flowing inside the pipe 1.

[0041] See Figure 3 The outer diameter of the sealing ring 11 is matched with the inner diameter of the pipe 1. The sealing ring 11 is made of rubber, which ensures the sealing performance when the outside of the baffle 9 contacts the inside of the pipe 1, and ensures that when the baffle 9 is closed, no gas will leak through the connection between the baffle 9 and the inner wall of the pipe 1.

[0042] See Figure 4 and Figure 5 The outer diameter of the filter screen 17 is matched with the inner diameter of the pipe 1, which ensures that all the gas flowing inside the pipe 1 must be filtered by the filter screen 17 before it can flow to the side of the filter screen 17 away from the baffle plate 9, thus ensuring the comprehensiveness of filtration.

[0043] See Figure 1 The outer edge of pipe 1 is uniformly coated with a galvanized layer, which ensures that pipe 1 will not be easily corroded after contact with air and rainwater, thus ensuring its service life.

[0044] Working principle: First, the temperature sensor 21 and the anemometer 22 can be used to monitor the air volume and gas temperature inside the pipe 1. At the same time, the bolt 7 can be loosened, and then the handle 4 can be turned to drive the rotating disk 3 to rotate. This will push the rotating rod 8 to drive the baffle 9 to rotate on the inner wall of the pipe 1, thereby regulating the air volume inside the pipe 1. The outer edge of the sealing ring 11 can be rotated to fit against the inner wall of the pipe 1 to ensure sealing. When the air flows, it will pass through the filter screen 17 to filter the impurities in the air. At the same time, the magnetism of the magnetic rod 19 will be eliminated, and the abutment plate 16 can be removed. Then, the magnetic rod 19 can be removed from the inner wall of the socket 18 to remove the filter screen 17, which will facilitate the maintenance and replacement of the filter screen 17.
