Description

Technical Field

[0001] This utility model belongs to the field of RTO technology, and more specifically relates to an easy-to-maintain RTO fan. Background Technology

[0002] In an RTO (Regenerative Thermal Oxidizer), there is a regenerator chamber that repeatedly switches between three states: intake, transition, and exhaust. When waste gas and fresh air are in motion, they are sent into the regenerator chamber by a fan. When the fan is damaged, the machine must be shut down for maintenance, which greatly affects the waste gas treatment efficiency. Moreover, maintenance can only be carried out at the original installation location of the fan, which results in high labor intensity for maintenance workers. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides an RTO fan that is easy to maintain.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an easily maintainable RTO fan, comprising a main delivery pipe and a secondary delivery pipe, both ends of which are connected to the main delivery pipe. A first fan is installed on the main delivery pipe, and a second fan is installed on the secondary delivery pipe. The inlet and outlet of the first fan are detachably connected to the main delivery pipe, and the inlet and outlet of the second fan are detachably connected to the secondary delivery pipe. Two first valves corresponding to the inlet and outlet of the first fan are installed on the main delivery pipe, and two second valves corresponding to the inlet and outlet of the second fan are installed on the secondary delivery pipe. Support mechanisms are provided between the first fan and the ground, and both the first fan and the second fan are slidably connected to the support mechanisms.

[0005] Furthermore, the support mechanism includes a support platform, on which a slide rail is provided, and a slider is provided on the support seat of the first fan and the second fan. The slider is slidably connected to the slide rail, and a drive mechanism is provided between the support seat and the support platform.

[0006] Furthermore, the driving mechanism includes a lead screw rotatably connected to the support platform and a nut fixed to the support base, and the nut is threadedly connected to the lead screw.

[0007] Furthermore, flanges are provided on the inlet and outlet of both the first and second fans.

[0008] Furthermore, the valve includes a valve body, a delivery pipe passing through the valve body, a sealing plate slidably connected inside the valve body, an opening corresponding to the sealing plate on the delivery pipe, a valve stem threadedly connected to the valve body, the valve stem being rotatably connected to the sealing plate, and sealing strips provided on both the sealing plate and the opening.

[0009] Compared with the prior art, the beneficial effects of this utility model are: when repairing the first fan, the exhaust gas can continue to be transported through the auxiliary conveying pipe without stopping the machine, and then the first fan can be moved away from its original installation position, which facilitates maintenance and reduces labor intensity.

[0016] Reference Figures 1 to 3 The present invention will be further described below.

[0017] An easily maintainable RTO fan includes a main delivery pipe 1 and a secondary delivery pipe 2. Both ends of the secondary delivery pipe 2 are connected to the main delivery pipe 1. A first fan 3 is installed on the main delivery pipe 1, and a second fan 4 is installed on the secondary delivery pipe 2. The inlet and outlet of the first fan 3 are detachably connected to the main delivery pipe 1, and the inlet and outlet of the second fan 4 are detachably connected to the secondary delivery pipe 2. Two first valves 5 are installed on the main delivery pipe 1 corresponding to the inlet and outlet of the first fan 3, and two second valves 6 are installed on the secondary delivery pipe 2 corresponding to the inlet and outlet of the second fan 4. Support mechanisms are installed between the first fan 3 and the second fan 4 and the ground, and the first fan 3 and the second fan 4 are slidably connected to the support mechanisms.

[0018] like Figure 2 As shown in the example, the preferred embodiment of this example includes a support platform 7, on which a slide rail 8 is provided. A slider 9 is provided on the support base 16 of the first fan 3 and the second fan 4. The slider 9 is slidably connected to the slide rail 8. A driving mechanism is provided between the support base 16 and the support platform 7.

[0019] like Figure 2 As shown, in this example, the preferred driving mechanism includes a lead screw 10 rotatably connected to the support platform 7 and a lead screw nut 11 fixed to the support base 16, and the lead screw nut 11 is threadedly connected to the lead screw 10.

[0020] Specifically, the lead screw 10 can be connected to a motor, which drives the lead screw 10 to rotate, or a handwheel can be provided at the end of the lead screw 10 to rotate it manually.

[0021] like Figure 2 As shown in this example, preferably, the first fan 3 and the second fan 4 are provided with flanges 12 at their inlet and outlet.

[0022] like Figure 3 As shown, in this preferred embodiment, the valve includes a valve body 13, a delivery pipe passing through the valve body 13, a sealing plate 14 slidably connected inside the valve body 13, an opening corresponding to the sealing plate 14 on the delivery pipe, a valve stem 15 threadedly connected to the valve body 13, the valve stem 15 being rotatably connected to the sealing plate 14, and a sealing strip (not shown in the attached figure) provided on both the sealing plate 14 and the opening.

[0023] Specifically, by rotating the valve stem 15, the sealing plate 14 can be driven to slide downward inside the valve body 13 until the opening of the delivery pipeline is sealed.

[0024] like Figures 1 to 3As shown, when the main conveying pipeline 1 is normally conveying exhaust gas, the two second valves 6 on the auxiliary conveying pipeline 2 are closed and the second fan 4 on it is stopped. When the first fan 3 on the main conveying pipeline 1 needs maintenance, the first valve 5 is closed, the second valve 6 is opened, and the second fan 4 is started, so that the exhaust gas is conveyed through the auxiliary conveying pipeline 2. The first fan 3 can be maintained without affecting the conveying of exhaust gas.

[0025] When maintaining the first fan 3, disconnect the connection between the inlet and outlet of the first fan 3 and the main conveying pipe 1, and then rotate the lead screw 10. Through the threaded engagement between the lead screw 10 and the lead screw 11, the support seat 16 is moved away from the main conveying pipe on the support platform 7 until it is moved out to create enough space for maintenance personnel to maintain the fan from all directions, which facilitates maintenance and reduces labor intensity.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
