[0002] A rotary dehumidifier is an important device at the end of a central air-conditioning unit. In the rotary dehumidifier, an electric heating tube exists as an important component, which is used to heat the regeneration air to remove the moisture in the rotary wheel so that the rotary wheel can continue to work.

[0003] During the operation of the unit, due to the gap between the fixed installation structure of the electric heating tube and the rock wool box, the sealing and heat preservation effects are poor. Moreover, due to the high-temperature working state of the electric heating tube, if there is a long-term leakage of high temperature, it is easy to cause the external temperature to rise, and then a fire may occur. To strengthen the sealing and heat preservation effects and maximize the heating effect of the electric heating tube, it is very important to design a new fixed installation plate structure for the electric heating tube.

[0004] Therefore, we propose a novel fixed installation structure of an electric heating tube with fire prevention and heat preservation to solve the problems mentioned above. Content of the Utility Model

[0031] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0032] As Figures 1-8 shown: A new type of electric heating tube fixed installation structure with fire prevention and heat preservation includes a fixing plate 1. An electric heating tube 2 is connected through the fixing plate 1, and the electric heating tube 2 is installed on the fixing plate 1 through a gasket nut 8, which facilitates the disassembly and assembly of the electric heating tube 2.

[0033] A spacer assembly for sealing and heat preservation is provided on the fixing plate 1. The spacer assembly is located between the fixing plate 1 and the electric heating tube 2, and rock wool is provided between the fixing plate 1 and the spacer assembly.

[0034] The spacer assembly includes a fixed cover plate 3. An asbestos gasket 4 is provided between the fixed cover plate 3 and the fixing plate 1. The fixed cover plate 3 and the fixing plate 1 are fixedly connected by blind rivets, which can not only ensure the sealing performance between the fixed cover plate 3 and the fixing plate 1, but also improve the fire prevention and heat preservation effect between the fixed cover plate 3 and the fixing plate 1.

[0035] The fixed cover plate 3 is also connected through the electric heating tube 2. The density of the rock wool inside the fixed cover plate 3 is 120 KG / M3, which strengthens the heat insulation effect between the fixed cover plate 3 and the fixing plate 1.

[0036] A disassembly assembly for replacing the rock wool between the fixing plate 1 and the spacer assembly is provided on the fixing plate 1. The disassembly assembly is located outside the fixing plate 1.

[0037] The disassembly assembly includes a movable plate 5. An asbestos gasket 4 is also provided at the connection between the movable plate 5 and the fixing plate 1 to ensure the sealing effect between the movable plate 5 and the fixing plate 1.

[0038] A rotating handle 6 and a knob 7 are installed on the outside of the movable plate 5. A ratchet 14 and a pawl 15 that cooperate with each other are installed inside the movable plate 5. A turntable 10 is installed on the inner side of the movable plate 5. The rotating handle 6, the ratchet 14, and the turntable 10 are fixedly connected and form a rotating structure on the movable plate 5, which facilitates the rotation of the ratchet 14 and the turntable 10 by rotating the rotating handle 6. The knob 7 is fixedly connected to the pawl 15 and also forms a rotating structure on the movable plate 5, which can control the locking state of the ratchet 14 and the pawl 15.

[0039] A push rod 11 is connected to the turntable 10. The outer end of the push rod 11 is connected to a sliding plate 12. Both ends of the push rod 11 are movably connected to the turntable 10 and the sliding plate 12. A limiting block 13 is arranged on the sliding plate 12. The limiting block 13 is fixed to the inner side of the movable plate 5. The position movement of the sliding plate 12 can be controlled by the rotation of the turntable 10, and then the disassembly and assembly work of the movable plate 5 on the fixed plate 1 can be controlled.

[0040] The sliding plate 12 is connected through the limiting block 13. The movement state of the sliding plate 12 can be restricted by the limiting block 13, ensuring the directional and stable movement of the sliding plate 12. The outer end of the sliding plate 12 is connected to a fastening block 9. The fastening block 9 is integrally provided with the movable plate 5 in an inclined convex shape. Through the connection between the fastening block 9 and the sliding plate 12, the installation state stability of the movable plate 5 can be strengthened.

[0041] Working principle: When using this fixed installation structure of the electric heating tube, first, align and connect the fixed cover plate 3 with the fixed plate 1, align the fixing holes on the fixed cover plate 3 and the fixed plate 1, and then strengthen the fixation through blind rivets. Before that, an asbestos gasket 4 needs to be placed between the fixed cover plate 3 and the fixed plate 1, which can not only improve the heat insulation effect at the connection between the fixed cover plate 3 and the fixed plate 1 but also ensure the sealed connection between the two;

[0042] After the fixed cover plate 3 and the fixed plate 1 are fixed, the wiring copper row of the electric heating tube 2 can be passed through the installation holes on the fixed cover plate 3 and the fixed plate 1, and then locked and fixed through a gasket nut 8 to complete the installation work of the electric heating tube 2 on the fixed cover plate 3 and the fixed plate 1. After the electric heating tube 2 is fixedly installed, the movable plate 5 on the fixed plate 1 can be opened, and rock wool can be filled into the space between the fixed plate 1 and the fixed cover plate 3 to ensure the overall heat preservation, heat insulation, and fire prevention effects of the fixed cover plate 3 and the fixed plate 1;

[0043] When the movable plate 5 needs to be opened, first rotate the knob 7 on the movable plate 5 to make the pawl 15 inside the movable plate 5 tilt up, releasing the limiting state of the ratchet wheel 14, so that the rotating ratchet wheel 14 can rotate. Then rotate the rotating handle 6, which can drive the turntable 10 inside the movable plate 5 to rotate. The rotation of the turntable 10 can pull the sliding plate 12 to move inward into the movable plate 5 through the push rod 11. When the sliding plate 12 moves and disconnects from the fastening block 9 inside the fixed plate 1, the fixation of the movable plate 5 on the fixed plate 1 can be released, and the movable plate 5 can be directly removed from the fixed plate 1, facilitating the filling of rock wool into the space between the fixed plate 1 and the fixed cover plate 3;

[0044] After the rock wool filling is completed, the movable plate 5 needs to be reinstalled, and then the rotating handle 6 can be rotated in the reverse direction. The sliding plate 12 will move outward from the movable plate 5. As the sliding plate 12 moves, the front end of the sliding plate 12 will press against the fastening block 9. At the same time, since the fastening block 9 is arranged with an inclined surface, as the position of the sliding plate 12 on the fastening block 9 moves forward, it can pull the movable plate 5 tightly against the fixed plate 1. At the same time, with the cooperation of the ratchet 14 and the pawl 15, the state of the sliding plate 12 is stabilized, thus completing the installation and fixation of the movable plate 5 on the fixed plate 1;

[0045] When the subsequent electric heating tube 2 has been working for a long time, if the rock wool inside has changed its properties due to long-term heating, the rock wool can be directly replaced by removing the movable plate 5 to ensure the long-term heat insulation and fire prevention effects of the fixed plate 1 and the fixed cover plate 3.

[0046] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.

[0047] The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
