Description

Technical Field

[0002] The combustion control fan refers to the fan used to assist the hot air circulation in the combustion control system. Similar to the traditional fan, it is directly installed between the coal-fired hot blast stove and the oven, or can also be directly installed at the flue of the combustion control system. For example, in the existing patent with the publication number CN202570576U, "a semi-automatic high-efficiency coal-fired hot air circulation heating system, including an oven, a coal-fired hot blast stove, a circulation fan, a control system, and a combustion control fan. The circulation fan is connected to the coal-fired hot blast stove through a closed pipeline, and a sensor is arranged in the circulation fan. The oven is connected to the circulation fan through a closed pipeline, and the oven is provided with a flue." It can be seen that both the circulation fan and the combustion control fan in this application are a kind of combustion control fan;

[0003] When this kind of combustion control fan in the prior art is actually used, in order to reduce noise and achieve silence, sound insulation cotton is generally installed on the inner wall of the fan air duct. However, the sound insulation cotton is generally installed by means of bonding and other fixing methods, resulting in low convenience for disassembly and assembly of the sound insulation cotton in the later stage. At the same time, there is no well-designed sealing structure at the connection between the existing combustion control fan and the outer wall of the oven of the combustion control system, and hot air leakage may occur, increasing the overall energy consumption of the combustion control system. Therefore, the utility model proposes a combustion control silent fan. Content of the Utility Model

The sound insulation cotton 17 is composed of aluminum foil + high-temperature resistant and flame-retardant cotton, and has certain sound insulation and sound absorption performance;

[0023] The installation structure provided between the sound insulation cotton 17 and the air outlet 12 includes an annular installation groove 171 opened on the surface of the sound insulation cotton 17, an annular rubber seat 172 embedded in the annular installation groove 171, a plurality of T-shaped card heads 173 provided on the surface of the annular rubber seat 172, and a plurality of T-shaped card slots 121 opened on the inner wall of the air outlet 12. The T-shaped card heads 173 are snapped into the T-shaped card slots 121 to ensure the installation stability of the sound insulation cotton 17. In the later stage, if the sound insulation cotton 17 needs to be removed for replacement, only need to pull the sound insulation cotton 17 forcefully, so that the T-shaped card heads 173 are elastically deformed by extrusion and pulled out from the T-shaped card slots 121, and the sound insulation cotton 17 can be removed from the inner wall of the air outlet 12 for replacement.

[0024] Among them, a rubber gasket sleeve 16 is sleeved on the surface of the socket 18, and the rubber gasket sleeve 16 fills the gap between the mounting base 14 and the oven 3. Two integral annular protrusions 161 are provided on the surface of the rubber gasket sleeve 16, both of which are made of fluororubber and will undergo elastic deformation when squeezed. Annular grooves 311 corresponding to the annular protrusions 161 are provided on the surface of the oven 3 and the inner wall of the connection port 31. The annular protrusions 161 are embedded in the annular grooves 311, which can ensure the sealing performance after the air outlet 12 is connected to the oven 3. When the fixing bolt A 15 is fully tightened, the rubber gasket sleeve 16 will be squeezed and undergo elastic deformation, filling the gap between the mounting base 14 and the oven 3, and the annular protrusions 161 will also be squeezed into the annular grooves 311 for further sealing to prevent hot air leakage and reduce the overall energy consumption of the combustion control system.

[0025] Among them, a plurality of bolt holes corresponding to the fixing bolt A 15 are provided on the surface of the rubber gasket sleeve 16 for the subsequent smooth penetration of the fixing bolt A 15.

[0026] Among them, the annular rubber seat 172 and the T-shaped chuck 173 are of an integral structure, both of which are made of fluororubber and will undergo elastic deformation when squeezed. An oval cavity corresponding to the T-shaped chuck 173 is provided in the annular rubber seat 172, so that the T-shaped chuck 173 has sufficient deformation space when squeezed.

[0027] Embodiment 2

[0028] Please refer to Figures 1 to 5 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The difference is that the hot air passing through the air inlet 11 can be filtered to a certain extent through the provided filtering structure 13, and the filtering structure 13 is convenient for disassembly, installation, maintenance and repair in the later stage.

[0029] Specifically, the filtering structure 13 includes an end plate 131 fixed on the top surface of the air inlet 11 and a metal filter frame 132 welded and fixed to the bottom surface of the end plate 131. A disassembly and installation opening 112 for inserting the metal filter frame 132 is provided on the top surface of the air inlet 11. A U-shaped seat 111 corresponding to the metal filter frame 132 is fixed on the inner wall of the air inlet 11. The metal filter frame 132 is inserted into the inner side of the air inlet 11 through the disassembly and installation opening 112, and the bottom end of the metal filter frame 132 is inserted into the inner side of the U-shaped seat 111. Under the action of the metal filter frame 132, the hot air passing through the air inlet 11 will be roughly filtered by the metal filter frame 132 to prevent some larger particles in the hot air from entering the main body 1 of the combustion control fan. In the later stage, only need to remove the fixing bolt B 133 regularly, and then lift the end plate 131, and the metal filter frame 132 can be pulled out for cleaning, maintenance or replacement.

[0030] Wherein, a return-shaped rubber sleeve 134 is sleeved on the top surface of the metal filter frame 132, and the return-shaped rubber sleeve 134 is in close contact with the inner wall of the disassembly and assembly port 112 to ensure the sealing performance after the installation of the metal filter frame 132. The filtering structure 13 further includes a plurality of fixing bolts B133. The end plate 131 is fixed to the top surface of the air inlet 11 through the plurality of fixing bolts B133, realizing the stable installation of the end plate 131.
