Description

Technical Field

[0001] The invention relates to the technical field of incinerator heat insulation, and in particular to a support assembly for a refractory hanging plate of a garbage incinerator. Background Art

[0002] In the field of industrial waste treatment, incinerators are core equipment, and the stability of their internal structure directly affects incineration efficiency and equipment life. Existing incinerator panel installation processes typically rely on support brackets fixed to the water-cooled wall wings for support and positioning. The panel is initially mounted on the support brackets, and then a fluid material is injected into the gap between the panel and the water-cooled wall, where it solidifies to form a connection. This installation method satisfies the panel's fixing requirements at room temperature. The fluid material not only fills the gap but also helps strengthen the connection between the panel and the water-cooled wall.

[0003] However, the high temperature environment generated during the operation of the incinerator will have a significant impact on the installation structure. When the heat in the furnace is transferred to the load-bearing parts and the fluid material, the two will produce different degrees of expansion and deformation due to the difference in thermal expansion coefficient. The load-bearing parts are mostly made of metal, and the thermal expansion amplitude is relatively stable, while the fluid material (such as refractory castables, etc.) may cause the expansion amount to fluctuate due to changes in physical structure at high temperatures. The mutual top pressure stress generated by the expansion of the two will be concentrated on the hanging part of the load-bearing parts. In long-term operation, this continuous top pressure can easily cause the load-bearing parts to bend and deform, or even cause structural damage. Once the load-bearing parts fail, it will directly weaken the supporting stiffness of the hanging plate, causing the hanging plate to move, loosen, and other problems. It will not only affect the airflow distribution and heat conduction in the incinerator, but may also cause safety hazards such as the hanging plate falling off. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the support parts for positioning the hanging plates on the water-cooled walls are easily damaged due to thermal expansion of the materials in a high temperature environment, and to provide a support assembly for the refractory hanging plates of a waste incinerator.

[0005] The present invention solves the above-mentioned technical problems and adopts the following technical solutions: a support assembly for a refractory cladding plate of a waste incinerator, comprising a support member that can be fixed to a water-cooled wall, the support member being connectable to a mounting cladding plate to position the mounting cladding plate on the water-cooled wall;

[0006] The support member is provided with a deformable member, which can deform during the use of the mounting plate to increase the space between the support member and the mounting plate;

[0007] The deformable member has one of the following two structural forms:

[0008] Form 1: The deformable member includes a deformable cavity provided on the support member, and the deformable cavity contracts and deforms when the support member is under pressure;

[0009] Form 2: The deformable member includes a heat shrink sleeve mounted on the support member, and the heat shrink sleeve can shrink and deform when the mounting plate is heated.

[0010] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: the support member is a connecting hook or a bearing nail that can be connected to the connecting hole opened on the installation hanging plate, and the connecting hook or the bearing nail is made of a tough metal alloy.

[0011] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: the connecting hooks or the bearing nails are made of metal alloys such as aluminum alloy or stainless steel.

[0012] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: a welding seat is fixedly provided on the end of the connecting hook facing the water-cooled wall.

[0013] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: the end of the load-bearing nail facing the water-cooled wall is provided with a welding chamfer.

[0014] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: the heat shrink sleeve and the support member are detachably connected together.

[0015] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: the heat shrink sleeve is interference fit with the support member.

[0016] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: the heat shrink sleeve is made of plastic or rubber material, and the end of the heat shrink sleeve away from the water-cooled wall is provided with a flared portion.

[0017] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: deformation grooves are evenly opened on the inner wall of the deformation cavity, and the deformation grooves are arranged horizontally to increase the vertical deformation of the support member.

[0018] As a further optimization of the support assembly for the refractory hanging plate of a waste incinerator of the present invention: the deformation cavity is a through hole with a water droplet-shaped cross section.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention positions the mounting plate on the water-cooled wall by connecting a support member to the water-cooled wall, ensuring an appropriate spacing between the two. Subsequently, operators can conveniently inject fluid material between the water-cooled wall and the mounting plate, successfully securing the mounting plate. The support member is equipped with a deformable element. When the mounting plate is used in the high-temperature environment of a heat source incinerator, this deformable element can reduce its own volume due to environmental factors, reserving space for thermal expansion of the support member and the fluid material. This effectively reduces the risk of damage caused by mutual pressure between the support member and the fluid material, thereby reducing the adverse effects of thermal expansion on the positional stability of the mounting plate.

[0027] In order to better understand the present invention, the content of the present invention is further illustrated below in conjunction with examples, but the content of the present invention is not limited to the following examples.

[0028] <Example 1>

[0029] like Figure 1 and Figure 2As shown, a support assembly for a refractory hanging plate of a waste incinerator has a support member 1 for connecting a water-cooled wall 5 and installing a hanging plate 3. The support member 1 includes a connecting hook 102. The end of the connecting hook 102 facing the water-cooled wall 5 is provided with a welding seat 101 that can be welded to the wing of the water-cooled wall 5. The connecting hooks 102 are fixed to the welding seat 101. These hooks are tightly connected to the hanging plate under the strong connection support between the welding seat 101 and the water-cooled wall 5, and the hanging plate is cleverly hung on the water-cooled wall 5. This design not only makes it convenient for operators to pour fluid materials between the water-cooled wall 5 and the hanging plate, but also realizes the rapid installation and positioning of the hanging plate. In the high temperature environment of the waste incinerator, the connecting hooks 102 and the fluid material will inevitably expand due to the influence of heat. However, when both the fluid material and the connecting hook 102 expand, they press against each other. This is when the connecting hook 102 reveals its key feature: a deformable element 2 is located at its center, allowing the hook 102 to deform. This deformable element 2 includes a deformation chamber 201, providing the necessary space for the fluid material to expand. The deformation provided by the deformation chamber 201 ensures that the connecting hook 102 will not break or be damaged by the pressure of the expanding fluid material, thereby ensuring that the connecting hook 102 provides stable support for the hanging board and ensuring the safety and reliability of the entire hanging board installation.

[0030] When the connecting hook 102 is subjected to pressure, the deformation cavity 201 allows the connecting hook 102 to deform inward. This elastic deformation not only provides ample space for the fluid material to expand, but also ensures that the connecting hook 102's ability to support the hanging plate is not affected. The deformation cavity 201 is defined at the end of the connecting hook 102 facing away from the welding base 101. This end is bulged, and the size of the bulged portion is carefully designed to ensure that it is larger than the inner diameter of the hanging plate docking groove. When the connecting hook 102 is connected to the hanging plate docking groove, the deformation cavity 201 imparts elastic deformation to the connecting hook 102, enabling it to effectively press against the hanging plate, further enhancing the supporting stability of the hanging plate and ensuring that the hanging plate remains stable even under high temperature and pressure, preventing it from loosening or falling off unexpectedly. The deformation groove 202 is an arc-shaped through-hole that runs vertically through the connecting hook 102. This maintains the structural stability of the connecting hook 102 and allows the connecting hook 102 to deform when under pressure, thus achieving deformation without damaging its own structure. The portion where the connecting hook 102 engages the clasp occupies one-tenth of the total length of the connecting hook 102. This allows a certain gap to be maintained between the clasp and the water-cooled wall 5 when the connecting hook 102 is connected to the positioning clasp, thereby providing conditions for the injection of fluid material. Specifically, the connecting hook 102 is made of a metal alloy such as aluminum alloy or stainless steel.

[0031] The connecting hook 102 and welding base 101 are made of a strip of metal material, with the ends aligned after bending. The bent portion is not flattened, thus cleverly forming a deformation cavity 201. This design not only ensures the sturdiness of the welding base 101 but also gives the connecting hook 102 the ability to elastically deform under load. This bending and alignment of the metal material not only ensures structural strength but also provides the necessary deformation space, allowing the entire support system to maintain its functional integrity and reliability even under the extreme operating conditions of a waste incinerator.

[0032] The outer perimeter of the connecting hook 102 is defined by a deformation groove 202. This not only helps reduce the overall weight of the connecting hook 102 but also further increases its deformation. The design of the deformation groove 202 provides more space for the connecting hook 102 to accommodate the expansion of the fluid material, further reducing the likelihood of the hanging plate loosening due to damage to the connecting hook 102. This improved configuration of the deformation groove 202 not only improves the installation efficiency of the hanging plate but also significantly enhances the stability and durability of the entire system, providing a solid foundation for the efficient operation of the waste incinerator.

[0033] <Example 2>

[0034] The principle of this embodiment is basically the same as that of embodiment 1, but the difference from embodiment 1 is that Figure 3 and Figure 4 As shown, the support member 1 is a load-bearing nail 104 that can be welded to the wing of the water-cooled wall 5. The load-bearing nail 104 can match the pre-set snap-in hole 4 on the mounting plate 3, thereby accurately positioning the mounting plate 3 on the wing of the water-cooled wall 5 and firmly positioning the mounting plate 3 on the surface of the water-cooled wall 5. The load-bearing nail 104 can be smoothly inserted into the deformable member 2, that is, it can be inserted into the docking hole 206 defined in the center of the heat shrink sleeve 203 included in the deformable member 2, so that the heat shrink sleeve 203 tightly wraps around the outer periphery of the load-bearing nail 104. The synergistic effect of the heat shrink sleeve 203 and the load-bearing nail 104 can significantly improve the stability of the snap-in connection between the load-bearing nail 104 and the snap-in hole 4, thereby enhancing the accuracy and stability of the load-bearing nail 104 in positioning the mounting plate 3. After the support pins 104 and the heat shrink sleeve 203 position the mounting plate 3 on the wing of the water-cooled wall 5, the operator can inject a specific fluid material between the water-cooled wall 5 and the mounting plate 3 to further stabilize the installation of the mounting plate 3 on the water-cooled wall 5. This not only effectively protects the water-cooled wall 5, but also successfully blocks heat from penetrating the water-cooled wall 5, ensuring that the side of the water-cooled wall 5 away from the heat source maintains a lower temperature.

[0035] The ends of the load-bearing pins 104 where they are attached to the wing of the water-cooled wall 5 are provided with welding chamfers 103. These chamfers facilitate welding the load-bearing pins 104 to the water-cooled wall 5 for use, thereby improving the installation efficiency of the load-bearing pins 104 and the heat shrink sleeve 203. The load-bearing pins 104 are made of a metal alloy such as aluminum alloy or stainless steel.

[0036] Heat shrink sleeve 203 is made of high-performance plastic, rubber, and specialized materials capable of deforming and significantly reducing in extreme high-temperature environments. Under the influence of heat released by the heat source, heat shrink sleeve 203 melts and burns, significantly reducing its volume. In particular, when heat shrink sleeve 203 is made of rubber, it melts and burns to an ash-like state in high-temperature environments, significantly reducing its volume. As heat shrink sleeve 203 melts and burns under high temperatures, reducing its volume, the space between engaging hole 4 and support pin 104 increases accordingly. After the heat shrink sleeve 203 is converted into an ash-like substance, the gap between the clamping hole 4 and the supporting nail 104 is further expanded. At this time, the expansion effect of the fluid material and the supporting nail 104 in a high temperature environment will effectively fill this gap. This not only improves the stability of the supporting nail 104 and the fluid material in jointly supporting and positioning the installation hanging plate 3 to the wing of the water-cooled wall 5, but also greatly reduces the risk of damage to the supporting nail 104 due to mutual pressure between the fluid material and the supporting nail 104, thereby reducing the possibility of a decrease in the stability of the installation hanging plate 3 caused by damage to the supporting nail 104.

[0037] The end of the heat shrink sleeve 203 facing away from the water wall 5 is provided with a flared portion 204 structure. The flared portion 204 fully utilizes the elastic properties of the heat shrink sleeve 203 itself during the key process of engaging the support nail 104 and the heat shrink sleeve 203 with the engaging hole 4 of the mounting bracket 3, effectively assisting in maintaining the stability of the engaging hole 4 between the support nail 104 and the mounting bracket 3, thereby significantly enhancing the support stability of the support nail 104 on the mounting bracket 3. Figure 4 As shown, a threaded area 205 is carefully defined within the docking hole 206 at the center of the heat shrink sleeve 203. The threaded area 205 mates with the threads at the end of the load-bearing pin 104, and an appropriate gap is reserved between the load-bearing pin 104 and the docking hole 206, allowing for a transitional fit between the load-bearing pin 104 and the heat shrink sleeve 203. This allows the operator to easily and accurately insert the load-bearing pin 104 into the docking hole 206, ensuring a secure connection between the load-bearing pin 104 and the heat shrink sleeve 203. This further facilitates the simultaneous and stable insertion of the load-bearing pin 104 and the heat shrink sleeve 203 into the engaging hole 4, achieving precise positioning of the mounting bracket 3 to the wing of the water-cooled wall 5. Furthermore, the load-bearing pin 104 can also achieve an interference fit with the heat shrink sleeve 203, further enhancing the connection stability between the load-bearing pin 104 and the heat shrink sleeve 203. Alternatively, the connection stability between the load-bearing pin 104 and the heat shrink sleeve 203 can be maintained without the threaded area 205.

[0038] like Figure 5 As shown, the depth of the heat shrink sleeve 203 and the supporting nail 104 inserted into the clamping hole 4 accounts for one tenth or two tenths of the total length of the supporting nail 104, thereby ensuring that the installation hanging plate 3 is accurately positioned to the wing of the water-cooled wall 5, and at the same time, a certain distance between the installation hanging plate 3 and the water-cooled wall 5 is cleverly maintained, which provides convenience for subsequent operators to smoothly inject fluid materials between the water-cooled wall 5 and the installation hanging plate 3, thereby facilitating the operators to complete the further connection and positioning purpose of the installation hanging plate 3 and the water-cooled wall 5.
