Technical Field

[0001] The utility model relates to the technical field of oil fume purifiers, in particular to a sound insulation structure of a large oil fume purifier. Background Art

[0002] A fume purifier is a device that treats cooking fume exhaust. It's primarily used to purify low-level kitchen fumes; in hotels, restaurants, schools, government offices, factories, and other places; in food frying and cooking; and in industrial settings like oil-splash heat treatment workshops, oil mist lubrication workshops, welding workshops, and olefin boiler emissions.

[0003] For example, an external exhaust pipe for an oil fume purifier with application number CN202122039172.8 and authorization announcement date 20220201 includes a pipe, a sealing plate, a sealing ring, a steel pipe and sound insulation cotton. A hollow groove is provided on the inside of the pipe, the steel pipe is arranged in the hollow groove, and the sealing plate is provided on the outside of the pipe. The sealing ring is located outside the sealing plate. When the external oil fume purifier is connected, the sealing ring and the oil fume purifier can fit tightly when bolts are used. Because the sealing ring is made of rubber, it deforms under force and can effectively seal and block the connection between the oil fume purifier port and the pipe port, improve the sealing of the connection, and prevent oil fume from leaking. In addition, this device is easy to install, which reflects the practicality and versatility of this device. The double-layer pipe wall is filled with sound insulation cotton, which not only improves the sound insulation performance of the pipe, but also uses stainless steel pipes to increase the strength of the overall frame support of the pipe, thereby improving the strength and service life of the pipe.

[0004] When a large-scale oil fume purifier is in operation, the air flows at a faster speed and produces a loud noise when flowing in the pipe, resulting in noise pollution when the oil fume purifier is in operation, which will have a greater impact on the surrounding people. Therefore, it is urgent to design a sound insulation structure for a large-scale oil fume purifier to solve the above problem. Utility Model Content

[0008] Furthermore, a knob end is integrally formed at one end of the threaded rod, and the knob end is exposed from the base.

[0009] Furthermore, the bottom of the connecting air duct is mounted on the top of the sliding block by means of bolts, and a sealing strip is sleeved on the outside of the connecting air duct.

[0010] Furthermore, two ear plates are integrally formed on the outer walls on both sides of the base, and a through hole is opened on the outer wall on one side of the top of the ear plate.

[0011] Furthermore, an outer wall on one side of the top of the base is provided with a placement groove, and a plurality of spring shock absorbers are installed on the bottom of the inner wall of the placement groove through bolts.

[0012] Furthermore, the output ends of the plurality of spring shock absorbers are mounted with support seats via bolts, and the support seats are slidably connected to the interior of the placement groove.

[0013] Furthermore, two support rods are threadedly connected to the outer walls on both sides of the top of the installation component, and rain covers are installed on the tops of the four support rods through bolts.

[0014] In the above technical solution, the utility model provides a sound insulation structure for a large oil fume purifier, which has the following beneficial effects:

[0015] (1) Through the air duct assembly, when the large fume purifier is in operation, air will flow in and out of the air duct assembly.
