Description

Technical Field

[0001] This utility model relates to a maintenance vehicle, and more particularly to an atomizer maintenance vehicle. Background Technology

[0002] In waste-to-energy incineration plants, desulfurization and acid removal in flue gas purification systems often employ a semi-dry method. This method utilizes a high-speed rotating atomizer to atomize lime slurry into fine droplets, which are then sprayed into a reaction tower to transfer heat and react with the flue gas, absorbing SO2, SO3, HCl, and HF. In existing technology, the high-speed rotating atomizer is installed inside the reaction tower, directly contacting the high-temperature exhaust gas generated during waste incineration. This harsh working environment frequently leads to malfunctions. Maintenance typically involves using an electric hoist to lift the atomizer out of the reaction tower for simple repairs while it is in operation.

[0003] Currently, atomizer maintenance involves suspending the atomizer in mid-air to replace or clean the atomizing disc. Because the atomizer is suspended by a steel cable, manual support is required for replacement or cleaning. Due to long-term use, the atomizing disc accumulates a lot of lime, and the bottom bolts are severely corroded, making disassembly difficult. During disassembly, maintenance personnel must squat with their heads tilted back. The atomizer, suspended in mid-air, constantly sways, making it difficult to apply leverage and further complicating disassembly. Since the atomizer is relatively heavy (approximately 300 kg), it cannot be leveled manually. Therefore, a device is urgently needed that can easily level the atomizer, clean the lime from the atomizing disc, or replace the atomizing disc. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses an atomizer maintenance cart, which allows for easy flattening of the atomizer, followed by cleaning and replacement of the atomizing disc.

[0005] The technical solution of this utility model is as follows:

[0006] A nebulizer repair vehicle includes a repair frame with a support for placing a nebulizer. The support has an opening in the middle corresponding to the support structure of the nebulizer. A positioning rod for positioning the nebulizer is vertically provided on the support and is located outside the opening. One side of the support is rotatably connected to the repair frame via a rotating mechanism.

[0007] Using this technical solution, after the atomizer is hoisted, it is placed in the opening in the middle of the support. The positioning rod is used to position the atomizer and can also assist other parts in fixing the atomizer. Then, the support is driven to rotate by the rotating mechanism, which can adjust the atomizer to the required angle or even lay it flat, making it convenient for maintenance and cleaning.

[0008] As a further improvement of this utility model, the rotating mechanism includes a bearing, which is located on one side of the support and fixedly connected to the maintenance vehicle frame; a support rod is vertically provided in the middle of the side of the support, and the maintenance vehicle frame is provided with a winch. The wire rope of the winch is connected to the top of the support rod. By rotating the winch, the wire rope of the winch drives the support to rotate around the bearing, thereby driving the atomizer to rotate.

[0009] Furthermore, the bearing can also be replaced by a simple steel tube with a round steel bar inserted inside, or a rotating shaft.

[0010] As a further improvement of this utility model, the top of the support rod is provided with a connecting hole, and the steel wire rope is connected to the connecting hole. Furthermore, the steel wire rope is connected to the connecting hole via a connecting buckle.

[0011] As a further improvement of this utility model, the winch is a hand-cranked winch or an electric self-locking winch.

[0012] As a further improvement of this utility model, the winch is located on the lower part of the side wall of the maintenance vehicle frame.

[0013] As a further improvement of this utility model, the inner ring of the bearing is fixed to the outer edge of the support, and the outer ring of the bearing is fixed to the maintenance vehicle frame.

[0014] As a further improvement of this utility model, there are two bearings, which are symmetrically located on one side of the support.

[0015] As a further improvement of this utility model, there are at least three positioning rods, which are evenly distributed around the opening and correspond to the notch of the atomizer.

[0016] As a further improvement of this utility model, the positioning rod is a screw rod, and a matching nut is used to fix the atomizer.

[0017] As a further improvement of this utility model, the bottom of the maintenance vehicle frame is provided with casters.

[0018] As a further improvement of this utility model, the maintenance frame includes a front support frame and a rear support frame, and the support is located between the support frame and the rear support frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] By adopting the technical solution of this utility model, the atomizer can be adjusted to the required angle or laid flat by rotating the support through the rotating mechanism. The maintenance vehicle has a simple structure, is easy to operate, saves effort, and improves maintenance efficiency. Attached Figure Description

[0028] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figures 1-5 As shown, an atomizer repair vehicle includes a repair frame 1, on which a support 2 for placing an atomizer is provided. The middle part of the support 2 has an opening 21 corresponding to the support structure of the atomizer. A positioning rod 22 for positioning the atomizer is vertically provided on the support 2. The positioning rod 22 is located outside the opening 21. One side of the support 2 is rotatably connected to the repair frame 1 through a rotating mechanism.

[0030] Specifically, the rotating mechanism includes a bearing 3, which is located on one side of the support 2 and is fixedly connected to the maintenance frame 1; further, the inner ring of the bearing 3 is fixed to the outer edge of the support 2, and the outer ring of the bearing 3 is fixed to the maintenance frame 1.

[0031] A support rod 4 is vertically provided in the middle of this side of the support 2. The maintenance frame 1 is provided with a winch 5. The top of the support rod 4 is provided with a connecting hole. The wire rope 6 of the winch 5 is connected to the connecting hole. By rotating the winch 5, the wire rope 6 of the winch 5 drives the support 2 to rotate around the bearing 3, thereby driving the atomizer to rotate.

[0032] The winch 5 is a hand-cranked or electric self-locking winch. The winch 5 is located on the lower part of the side wall of the maintenance frame 1.

[0033] Furthermore, there are two bearings 3, which are symmetrically located on one side of the support 2.

[0034] In this embodiment, there are three positioning rods 22, evenly distributed around the opening 21, corresponding to the notch of the atomizer. Each positioning rod 22 is a screw, with a matching nut for securing the atomizer.

[0035] Furthermore, the bottom of the maintenance frame 1 is equipped with casters 7, which facilitates moving the atomizer to a suitable position for maintenance.

[0036] Furthermore, the maintenance frame 1 includes two support frames 11 arranged at the front and rear, and the support 2 is located between the two support frames 11.

[0037] like Figures 3-5 As shown, using the technical solution of this embodiment, when the atomizer needs maintenance, the atomizer is lifted, the notch of the atomizer passes through the positioning rod 22, the atomizer is placed in the support 2, and three nuts are installed. At this time, the atomizer is fixed on the maintenance vehicle.

[0038] The winch 5 is manually cranked or started, thereby causing the support 2 to rotate 90° around the axis of the bearing 3.

[0039] When the maintenance is completed and the atomizer needs to be restored to a vertical position, rotate the winch 5 in the opposite direction. The atomizer will slowly rotate under its own weight. When the support 2 contacts the maintenance vehicle, the atomizer will be restored to a vertical position.

[0040] This technical solution allows for single-person operation, enabling the atomizer to be laid flat for inspection and maintenance. When laid flat, the atomizer protrudes entirely from the maintenance vehicle, facilitating the use of maintenance tools, unlike other solutions where half of the atomizer is located under the vehicle.
