[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] As Figures 1-4As shown, the utility model provides a technical solution: a quick replacement device for a blower static seal, comprising: a blower assembly 2, the blower assembly 2 is composed of a blower cover 21, a blower seat 22 and a blower motor 23 arranged in sequence from left to right, the bottom of the blower motor 23 is provided with an exhaust seat 24 for fixing the blower cover 21, the blower seat 22 and the blower motor 23; wherein the bottom of the exhaust seat 24 is connected to the blower seat 22, and the exhaust seat 24 is provided with a mounting seat 241; a sliding bottom plate 3, the sliding bottom plate 3 is arranged below the exhaust seat 24, and the sliding bottom plate 3 has a mounting seat for fixing the exhaust The mounting protrusion 31 and the mounting bolt 32 of the air seat 24, the mounting bolt 32 is threaded through the mounting seat 241, and the bottom of the mounting bolt 32 is correspondingly fixed on the mounting protrusion 31; wherein, a strip slider 33 is provided at the bottom of the sliding bottom plate 3; the dynamic and static sealing assembly 1, the dynamic and static sealing assembly 1 is used to provide a sealing effect for the blower assembly 2, the dynamic and static sealing assembly 1 includes an L-shaped main frame 12, a limiting top plate 11 and two side sound insulation boards 14 correspondingly connected to the two sides of the main frame 12, two columns 121 are provided on one side of the main frame 12, and a front The baffle 13 and the horizontal end of the main frame 12 are provided with a strip slide 18 for sliding connection of the strip slider 33. The sliding bottom plate 3 is slidably connected in the strip slide 18 through the strip slider 33. The column 121 and the side sound insulation board 14 are provided with a strip card groove 141. The limit top plate 11 is slidably connected with the column 121 and the top of the side sound insulation board 14 through the strip card groove 141. Since the blower assembly 2 needs to be disassembled and maintained in the later stage, the silent equipment where the blower assembly 2 is placed needs to be easy to disassemble. Therefore, the detachable structure can improve work efficiency during use, making installation more convenient. The assembly or disassembly is more convenient. Furthermore, during maintenance, the limiting top plate 11 is slid to one side to release the limiting state of the opposite side sound insulation plate 14. After the release is completed, the two side sound insulation plates 14 are unfolded to both sides to facilitate the maintenance of the blower assembly 2. The front baffle 13 can be further slid upward to pull the front baffle 13 out of the column 121. After the front baffle 13 is pulled out, the sliding bottom plate 3 is pulled out through the handle groove 34 to separate the blower assembly 2 from the dynamic and static sealing assembly 1, thereby further improving the convenience during maintenance and solving the technical problem of more convenient disassembly of the blower assembly 2.

[0036] A step further, such as Figures 2-4As shown: an air outlet pipe 17 is provided on the vertical end of the main frame 12 below the air inlet cover 16, and a mounting sleeve 171 is embedded in the air outlet pipe 17, and the mounting sleeve 171 is fixedly connected to the output end of the exhaust seat 24, and a fault-tolerant hole 172 is provided on the mounting sleeve 171. The fault-tolerant holes 172 are distributed in an annular shape, and the angles between two adjacent fault-tolerant holes 172 are equal. A sound-absorbing cotton 15 is embedded in the side sound insulation board 14, and a honeycomb hole 151 is provided in the sound-absorbing cotton 15, and the spacing between two adjacent honeycomb holes 151 is equal. Under the action of the air outlet pipe 17, it is fixedly connected to the exhaust seat 24, so that the gas discharged after the blower assembly 2 is turned on passes through the outlet The air pipe 17 is discharged, and under the action of the installation sleeve 171, it is used to protect the connecting pipe to prevent the blower assembly 2 from vibrating during use, causing the connecting pipe to touch the main frame 12 and thus produce abnormal noise. Further, under the action of the fault-tolerant hole 172, when the connecting pipe vibrates, vibration displacement space is reserved. Further, under the action of the sound-absorbing cotton 15, the sound emitted by the blower assembly 2 when in use is reduced. Further, under the action of the honeycomb hole 151, after the sound wave is transmitted to the honeycomb hole 151, the sound is reduced in the honeycomb hole 151, thereby achieving a silent sealing effect, and solving the technical problem of sealing and silent when the blower assembly 2 is turned on.

[0037] The above solution still has the problem that the blower assembly 2 cannot take in air, such as Figure 4 As shown: In this solution, an air intake hood 16 is provided at the vertical end of the main frame 12. The diameter of the air intake hood 16 is larger than the diameter of the input end of the blower motor 23. Under the action of the air intake hood 16, it serves as the main air intake channel when the blower assembly 2 is in use, thereby ensuring the stability of the blower assembly 2 during use.

[0038] The above solution also has the problem of inconvenience in pulling out the sliding bottom plate 3. Figure 4 As shown: In this solution, the sliding base plate 3 is located at one end of the blower seat 22 and a handle groove 34 is provided. Since the blower assembly 2 is installed on the sliding base plate 3, and the sliding base plate 3 and the main frame 12 are slidably connected, it is necessary to slide the sliding base plate 3 out of the main frame 12 during maintenance. At this time, under the action of the handle groove 34, it can serve as a fulcrum to make it easier to pull out the sliding base plate 3.

[0039] Working principle:

[0040] like Figures 1-4As shown, first place the device at the designated position, then insert the connecting pipe into the mounting sleeve 171 and securely connect it to the exhaust seat 24. After the connection is completed, open the blower assembly 2. During maintenance, slide the limiting top plate 11 to one side to release the limiting state of the opposite side sound insulation board 14. After the release is completed, unfold the two side sound insulation boards 14 to both sides to facilitate maintenance of the blower assembly 2. Further, the front baffle 13 can be slid upward to pull the front baffle 13 out of the column 121. After the front baffle 13 is pulled out, pull out the sliding bottom plate 3 through the handle groove 34 to separate the blower assembly 2 from the dynamic and static sealing assembly 1.
