Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen smoke exhaust, and more specifically relates to a through-hole foam ceramic silencer pipe. Background Art

[0002] A flue is a tubular device for discharging waste gas and smoke. A residential flue refers to a vertical pipe product used to remove kitchen smoke or bathroom waste gas. It is also called an exhaust duct, ventilation duct, or residential exhaust duct. A residential flue is the main component of the exhaust duct system shared by residential kitchens and bathrooms.

[0003] When designing exhaust systems in today's kitchens, the exhaust ducts are mostly made of metal or plastic materials. These materials are easily aged under the influence of high temperature and oil smoke, and will produce loud noise when the range hood is in use. In order to reduce noise, some current oil fume ducts use materials such as glass wool as a sound-absorbing layer. However, the glass surface is fragile, has poor wear resistance, and has a short service life. Fine fiber dust is easily generated during construction and installation, which can easily cause secondary pollution.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a through-hole foam ceramic silencer pipe is provided to achieve a more practical purpose. Utility Model Content

[0007] Furthermore, the interior of the sound-absorbing layer is filled with a through-hole foam ceramic material.

[0008] Furthermore, a pair of second mounting grooves are respectively formed on one side of a pair of mounting plates, and the second mounting grooves pass through both sides of the mounting plates.

[0009] Furthermore, a mounting bolt is movably provided in the second mounting groove of one of the pair of mounting plates.

[0010] Furthermore, the limiting plate is provided with a fixing hole corresponding to the first mounting groove.

[0011] Furthermore, the fixing hole is movably connected to a fixing bolt, and the other end of the fixing bolt extends into the first mounting groove and is threadedly connected to the first mounting groove.

[0012] Furthermore, the tube body is made of stainless steel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, the combination of the sound-absorbing layer and the through-hole foam ceramic material not only has a good sound-absorbing effect and can significantly reduce the exhaust noise, but is also resistant to high temperature and corrosion and has a long service life. At the same time, it is not easy to generate dust during construction. The setting of the network limit sleeve can effectively protect the through-hole foam ceramic material.
