[0002] In industries such as chemical, metallurgical, power, and glass, waste gas pipelines are widely used to transport high-temperature and highly corrosive gases generated during reaction processes or emissions to treatment devices. Existing pipeline support systems mostly use fixed flanges, simple supports, or universal joints combined with bolt connections, which have the following main shortcomings: poor spatial adaptability, the support structure is mostly single-plane or limited angle adjustment, which is difficult to meet the needs of complex three-dimensional pipeline layout, and repeated disassembly and repositioning are required during on-site installation, resulting in a long construction period; low height adjustment accuracy, traditional shims, nuts and washers can only achieve rough leveling, the fine adjustment range is limited, and it is impossible to accurately control the pipeline slope, affecting the exhaust gas flow and system efficiency; insufficient clamping reliability, existing elastic clamps often rely on metal spring sheets or hard rubber, which are prone to loosening or scratching the pipe body, and are prone to aging and failure in high temperature (>300℃) and strong corrosive environments; limited corrosion resistance, the base body is mostly made of carbon steel or low alloy steel, and only a single layer of paint or galvanizing treatment is applied. When exposed to humid heat, strong acids and alkalis, and sulfur- or fluorine-containing exhaust gases, the protective layer is prone to peeling off, shortening the life of the support components.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a support base for a waste gas treatment conveying pipe:

[0023] like Figure 1 and Figure 3As shown, the system includes a base body 1, a multi-axis rotating assembly 2, a pipe support arm 3, a flexible pipe clamp 4, and adjustable support feet 5. The base body 1 is integrally cast from a high-temperature and corrosion-resistant metal material such as SUS316L stainless steel, and its surface is coated with epoxy zinc-rich primer and polyurethane topcoat, providing excellent resistance to acid and alkali corrosion. The upper center of the base body has a mounting hole for the multi-axis rotating assembly 2, and its side walls have several cooling air ducts and lubrication filling holes to maintain the joint in good working condition. The base body 1 has threaded holes for adjustable support feet 5 at the four corners of its bottom surface. The multi-axis rotating assembly 2 is fixed on the base body 1 and is used to rotate the pipe support arm 3 around multiple spatial coordinate axes and achieve arbitrary positioning through locking components. The elastic pipe clamp 4 is threaded onto the far end of the pipe support arm 3 and is used to elastically clamp and fix the exhaust gas conveying pipe. The adjustable support feet 5 are bolted to the bottom of the base body 1 and are used to achieve precise correction of the support height through thread adjustment. Elastic shock-absorbing pads are provided at the bottom to absorb operating vibrations. The base body 1 is integrally cast from high-temperature and corrosion-resistant metal materials and coated with a multi-layer acid and alkali resistant composite coating to adapt to long-term operation in high-temperature, high-humidity and highly corrosive gas environments.

[0024] like Figure 2 As shown, the multi-axis rotating assembly 2 includes a circular joint 21, a rotating shaft 22, and an angle scale 23. The rotating shaft 22 is detachably connected to the angle scale 23 via a locking nut. After the user rotates the locking nut to unlock it, the circular joint 21 drives the pipe support arm 3 to adjust the angle arbitrarily in the X, Y, and Z directions. The required angle is precisely locked by the scale of the scale 23 and the locking nut.

[0025] like Figure 4 As shown, the elastic pipe clamp 4 is made of shape memory alloy or high-strength polyurethane material. The inner wall of the pipe clamp is lined with a high-temperature resistant rubber pad to ensure both clamping firmness and pipe surface protection. The internal high-temperature resistant rubber pad ensures adaptability to exhaust pipes with diameters of 50mm to 300mm and maintains elasticity over a long period of time in high-temperature environments. After the pipe clamp is tightened with a nut, the pipe is firmly fixed; after the nut is loosened, the pipe clamp automatically springs back, allowing for quick pipe removal.

[0026] like Figure 4 As shown, the adjustable support foot 5 consists of a support foot screw 51 and an anti-slip foot pad 52. The support foot screw 51 is engaged with the internal threaded hole of the base body 1, and the height can be adjusted by ±20mm stroke. By turning the threaded hole at the bottom of the base body 1, the height of the support foot can be quickly adjusted to adapt to uneven ground. The anti-slip foot pad 52 is made of high-damping rubber material, which not only ensures firm anti-slip but also absorbs pipeline vibration.

[0027] like Figure 3As shown, the top surface of the multi-axis rotating assembly 2 is bolted to a support block. A hole is provided on one side of the support block. A limiting rod 24 is fitted on the inner wall of the hole. One end of the limiting rod 24 passes through and is connected to the circular joint 21 from one side of the support block. Several limiting holes are provided on one side of the circular joint 21. The angle of the circular joint 21 is adjusted first. Then, the rotation angle of the circular joint 21 is fixed by threading by inserting the limiting rod 24 from the outside of the support block into the limiting hole of the circular joint 21 and rotating it.

[0028] like Figure 1 As shown, the base body 1 is made of one or a combination of stainless steel, nickel-chromium alloy or aluminum alloy treated with nano-ceramics, and its surface is coated with epoxy zinc-rich primer and polyurethane topcoat.

[0029] like Figure 3 As shown, the pipe support arm 3 is a modular structure, comprising two or more support sections 31. Each support section 31 is connected by a quick-connect fitting 32 to facilitate on-site disassembly, assembly, and transportation as needed.

[0030] The working principle of this utility model is as follows: First, the multi-axis rotating assembly 2 enables the orientation adjustment and locking of the waste gas conveying pipe. The pipe support arm 3 can rotate freely around the circular joint 21 on three coordinate axes: horizontal, vertical, and oblique. The limiting rod 24 is inserted into different limiting holes on the circular joint 21 to achieve mechanical locking. Then, the locking nut is tightened to eliminate micro-movement and ensure long-term stability of the pipe at the set angle. Second, the flexible pipe clamp 4 and the adjustable support foot 5 are combined to flexibly clamp the pipe and precisely adjust its height. The flexible pipe clamp 4 is made of shape memory alloy or high-strength polyurethane, and the inner wall is lined with high-temperature resistant rubber, which can automatically adapt to the changing environment. To accommodate the thermal expansion and contraction of the pipeline, a continuous and uniform clamping force is provided, protecting the pipeline surface and preventing loosening. The adjustable support foot 5 engages with the threaded hole of the base body 1 via the support foot screw 51, allowing for a ±20mm stroke adjustment of the height. The anti-slip foot pad 52 absorbs operational vibrations and maintains good contact between the base and the ground, ensuring overall levelness or the required slope. Finally, weather protection and intelligent control are achieved through the use of material and surface coating systems and optional automated fine-tuning components: the base body 1 is integrally cast from high-temperature and corrosion-resistant metal and coated with epoxy zinc-rich primer and polyurethane topcoat. The multi-layer composite coating can resist high temperature, high humidity, and strong corrosive gas erosion.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
