Abstract

This utility model discloses a support hook for a refractory hanging plate in a waste incinerator. It has a connecting hook that can be vertically fixed to the fins of a water-cooled wall, and the connecting hook can engage with the hanging plate to hang the hanging plate on the fins of the water-cooled wall.

Description

Technical Field

[0001] This utility model relates to the field of waste incineration power generation technology, specifically to a support hook for a refractory hanging plate of a waste incinerator. Background Technology

[0002] During the operation of waste incinerator power generation equipment, water-cooled walls and fireproof scrapers are crucial components ensuring the normal operation of the equipment. The installation and use of fireproof scrapers are particularly critical. Currently, existing fireproof scrapers require the injection of a fluid material for fixation during installation. However, after installation, the large amount of heat generated by the incinerator during operation significantly affects these scrapers. Due to the different coefficients of thermal expansion between the concrete and the scraper material, the difference in thermal expansion deformation under high temperatures causes them to press against each other. This pressing effect persists, eventually leading to bending damage to both the concrete and the scrapers. This bending damage directly affects the positional stability of the refractory brick scrapers, potentially causing displacement or loosening during equipment operation. This not only reduces the fire resistance of the equipment but may also affect the overall operational safety and efficiency of the waste incinerator power generation equipment. Utility Model Content

[0003] The purpose of this invention is to solve the problem that in the prior art, the support hooks of the positioning hanging plate are damaged due to the synchronous thermal expansion of the fluid material caused by environmental factors during use, which leads to mutual pressure. The invention provides a support hook for the refractory hanging plate of a waste incinerator.

[0004] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a support hook for a refractory hanging plate of a waste incinerator, which has a connecting hook that can be vertically fixed on the water-cooled wall fins, and the connecting hook can be engaged with the hanging plate to hang the hanging plate on the water-cooled wall fins.

[0005] The connecting hook is made of a tough material and has a deformation cavity on it for the connecting hook to deform under pressure.

[0006] As a further optimization of the refractory hanging plate support hook for waste incinerator of this utility model: the connecting hook is fixedly connected to a welding seat that can be welded together with the water-cooled wall fins.

[0007] As a further optimization of the support hook for the refractory hanging plate of the waste incinerator according to this utility model: the connecting hook has an arc-shaped expansion part at the engagement point with the hanging plate, and the expansion part is set corresponding to the deformation cavity. As a further optimization of the support hook for the refractory hanging plate of the waste incinerator according to this utility model: the connecting hook is made of aluminum alloy.

[0008] As a further optimization of the refractory hanging plate support hook for waste incinerator of this utility model: the outer periphery of the connecting hook is provided with a deformation groove for further deformation of the connecting hook.

[0009] As a further optimization of the refractory hanging plate support hook for waste incinerator of this utility model: the deformation cavity is a teardrop-shaped through hole that connects the hook from top to bottom.

[0010] As a further optimization of the refractory hanging plate support hook for waste incinerator of this utility model: the part of the connecting hook that can be engaged with the hanging plate accounts for one-tenth to two-tenths of the total length of the connecting hook.

[0011] As a further optimization of the refractory hanging plate support hook for waste incinerator of this utility model: the connecting hook and the welding seat are made by bending the ends of strip material and aligning them, and the bending naturally forms a deformation cavity.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention addresses the thermal expansion problem in the high-temperature environment of waste incinerators by incorporating a deformation cavity in the connecting hook. When the connecting hook and the fluid material expand due to heat and press against each other, the deformation cavity provides the conditions for the deformation of the connecting hook, thus reserving the necessary space for the expansion of the fluid material. The deformation provided by the deformation cavity effectively prevents the connecting hook from breaking due to the upward pressure generated by the expansion of the fluid material, ensuring the stable support of the connecting hook for the hanging plate, thereby guaranteeing the safety and reliability of the entire hanging plate installation.

[0018] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0019] <Example 1>

[0020] like Figure 1 and Figure 3As shown, a support hook for a refractory hanging plate 6 of a waste incinerator has a connecting hook 2 and a welding seat 1, specifically designed for welding onto the fins of a water-cooled wall 5. The connecting hook 2 is fixedly mounted on the welding seat 1. These hooks, supported by a robust connection between the welding seat 1 and the water-cooled wall 5, are tightly connected to the hanging plate 6, cleverly suspending the hanging plate 6 onto the water-cooled wall 5. This design not only facilitates the pouring of fluid materials between the water-cooled wall 5 and the hanging plate 6 by operators, but also enables rapid installation and positioning of the hanging plate 6. In the high-temperature environment of the waste incinerator, both the connecting hook 2 and the fluid material will inevitably expand due to heat. However, when both the fluid material and the connecting hook 2 expand, they will press against each other. At this point, the connecting hook 2 exhibits its key feature: a deformation cavity 3 is provided at the center of the connecting hook 2 to allow for deformation, thus providing the necessary space for the expansion of the fluid material. The deformation cavity 3 provides deformation capacity to ensure that the connecting hook 2 will not break due to the top pressure of the fluid material expansion, thus ensuring the stable support of the connecting hook 2 for the hanging plate 6 and ensuring the safety and reliability of the entire hanging plate 6 installation. When the connecting hook 2 is subjected to top pressure, the deformation cavity 3 allows the hook to deform inward. This elastic deformation not only provides sufficient space for the expansion of the fluid material but also ensures that the load-bearing function of the connecting hook 2 for the hanging plate 6 is not affected. The connecting hook 2 has a deformation cavity 3 at the end opposite to the welding seat 1, and this end bulges out. The size of the bulge is carefully designed to ensure that it is larger than the inner diameter of the mating groove of the hanging plate 6. When the connecting hook 2 is connected to the mating groove of the hanging plate 6, the deformation cavity 3 imparts elastic deformation to the connecting hook 2, enabling it to effectively press against the hanging plate 6, thereby further improving the support stability of the hanging plate 6 and ensuring that the hanging plate 6 remains stable under high temperature and pressure, without accidental loosening or falling off. The deformation groove 4 is an arc-shaped through hole that runs vertically through the connecting hook 2. This maintains the stability of the supporting structure of the connecting hook 2 and allows for deformation space under pressure, thus preventing damage to its own structure. The part where the connecting hook 2 engages with the mounting plate 6 occupies one-tenth of the total length of the connecting hook 2. This ensures that when the connecting hook 2 is connected to the positioning mounting plate 6 and the water-cooled wall 5, a certain gap is maintained between the mounting plate 6 and the water-cooled wall 5, providing conditions for the injection of fluid materials. Specifically, the connecting hook 2 is made of metal alloys such as aluminum alloy or stainless steel. The connecting hook 2 and the welding seat 1 are formed by aligning the bent ends of strip-shaped metal material. The bent part is not flattened, thus cleverly forming the deformation cavity 3. This design not only ensures the robustness of the welding seat 1 but also gives the connecting hook 2 elastic deformation capability under stress. This bending and alignment method of the metal material ensures both structural strength and provides the necessary deformation space, allowing the entire support system to maintain its functional integrity and reliability even under the extreme operating conditions of the waste incinerator. <Example 2> Figure 2 and Figure 3As shown, this embodiment, while inheriting the core advantages of embodiment 1, further optimizes the design of the connecting hook 2. Unlike embodiment 1, the connecting hook 2 has a deformation groove 4 on its outer periphery. The deformation groove 4 not only helps reduce the overall weight of the connecting hook 2 but also further increases its deformation capacity. The design of the deformation groove 4 allows the connecting hook 2 to provide more space when facing the expansion of fluid materials, thereby further reducing the probability of the hanging plate 6 loosening due to damage to the connecting hook 2. The improved design of the deformation groove 4 not only improves the installation efficiency of the hanging plate 6 but also significantly enhances the stability and durability of the entire system, providing a solid guarantee for the efficient operation of the waste incinerator. The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
