Description
TECHNICAL FIELD
[0001] The utility model relates to chute structure technical field, especially relate to a feed chute structure and garbage pool. BACKGROUND
[0002] In the garbage incineration power plant, garbage as fuel source, for guaranteeing the continuity of garbage incineration power plant operation, need to store a certain amount of garbage. Therefore, will build a concrete garbage pool in the garbage incineration power plant, for storing about 7 days of garbage amount, to supply the continuous operation of power plant.
[0003] All garbage is transported to garbage incineration power plant by municipal environmental sanitation garbage truck, after garbage truck enters the unloading platform, opens garbage door and pours garbage into garbage storage pit (or garbage pool). Different garbage door forms correspond to different garbage pouring ways. Except flat push type garbage door, the rest garbage door needs to set garbage pool chute, and garbage enters garbage storage pit through garbage pool chute. Among them, the inclination gradient of garbage pool chute, the anticorrosion mode of concrete, the wear resistance and anticorrosion method of surface can all affect the durability of garbage pool chute, and can also affect the process of continuously and smoothly putting garbage into garbage incineration power plant operation.
[0004] The existing garbage pool chute mainly adopts the following several wear-resistant and anticorrosion methods: the first kind is to make general wear-resistant treatment on the surface of concrete-made garbage pool chute, and then brush anticorrosive paint. Among them, the wear resistance of anticorrosive paint is poor, and with the passage of time, after the anticorrosive paint is rubbed off, the concrete surface layer will be gradually corroded, and the steel bars will also be gradually corroded. If this problem is not treated for a long time, it will affect the safety of the structural members of the garbage pool; however, frequent treatment and repair will also affect the operation of the garbage incineration project.
[0005] The second kind is to add steel plate or PVC (i.e. polyvinyl chloride) plate to the surface of concrete-made garbage pool chute, and then carry out wear-resistant and anticorrosion treatment. Among them, the anticorrosion effect of PVC plate is good, but there are the following defects: with the passage of time, it is easy to age, and after aging and cracking, it will cause leachate to seep into the concrete interior, thereby causing the PVC plate to lose the protection effect. In addition, for the general surface steel plate pasting method, the construction method is complex, and the quality is difficult to guarantee; if the steel plate warps or the joint leakage occurs, it will also cause leachate to corrode the concrete base layer, thereby unable to guarantee the good use durability of the garbage pool chute.

For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0036] Reference is made below to Figures 1 to 5 The feeding chute structure and the garbage pool are described according to the embodiments of the present application.
[0037] As Figures 1 to 5 As shown in the feeding chute structure 200 according to the first embodiment of the present application, the corrosion resistance and wear resistance of the feeding chute structure 200 can be improved, and the construction convenience and quality reliability can be ensured, thereby increasing the use durability of the feeding chute structure 200. The feeding chute structure 200 can be applied to the garbage inlet of the garbage pool, or can be applied to the inlet of other corrosive material storage bin.
[0038] The feeding chute structure 200 comprises a chute main body, a first wear-resistant steel plate 241, a second wear-resistant steel plate 242 and a pre-embedded part.
[0039] The chute main body is of a concrete structure and can be built by concrete pouring. The chute main body has a guide chute, the upper end opening of the guide chute is a feeding port, and the lower end opening of the guide chute is a discharging port. The guide chute can guide the corrosive material such as garbage. The guide chute has a guide bottom surface and two guide side surfaces. The guide bottom surface is inclined from top to bottom, and the guide bottom surface and the horizontal plane form an angle θ, and the angle θ is 55° to 60°. The two guide side surfaces are located at opposite sides of the guide bottom surface, and the guide side surface and the guide bottom surface can be perpendicular to each other or non-perpendicular.
[0040] In the embodiment, the chute body comprises a bottom wall 221 and two side walls 222. The thickness of the bottom wall 221 and the thickness of the side walls 222 can be set according to actual requirements, which are not specifically limited herein. The inclined surface of the bottom wall 221 is a material guiding bottom surface, and the inner side surface of the side wall 222 is at least partially a material guiding side surface. The material guiding bottom surface is inclined downward and backward from top to bottom, and the material guiding side surface is perpendicular to the material guiding bottom surface. The angle θ is set to 60°. It can be understood that the material guiding bottom surface and the material guiding side surface can be in contact with corrosive materials such as garbage, and the material guiding side surface can be less than or equal to the inner side surface of the side wall 222.
[0041] The material guiding bottom surface and the two material guiding side surfaces of the chute body are provided with a corrosion-resistant coating. It can be understood that after the chute body is poured and demoulded, the material guiding bottom surface and the material guiding side surface are polished to ensure good surface flatness. Then, the material guiding bottom surface and the material guiding side surface are sprayed with paint to form a corrosion-resistant coating with certain wear resistance. The corrosion-resistant coating can be made of a permeable crystalline corrosion-resistant coating, which has excellent wear resistance through the synergistic effect of a high-hardness crystalline layer, a dense structure and self-healing ability. Of course, the corrosion-resistant coating can be made of other materials to obtain good corrosion resistance. The material of the corrosion-resistant coating can be adjusted according to the characteristics of corrosive materials such as garbage.
[0042] Moreover, the material guiding bottom surface and the two material guiding side surfaces of the chute body are provided with a plurality of embedded parts. It can be understood that the number of embedded parts is selected according to actual needs, which is not specifically limited herein. The embedded parts are weathering steel parts or stainless steel parts, so that the embedded parts have excellent corrosion resistance and are not easily corroded. During the pouring and forming process of the chute body, the embedded parts are embedded in the designed positions of the chute body in advance.
[0043] The first wear-resistant steel plate 241 covers the material guiding bottom surface, and the first wear-resistant steel plate 241 is connected to the embedded parts on the material guiding bottom surface by plug welding, so that the first wear-resistant steel plate 241 is fixed on the material guiding bottom surface. The thickness of the first wear-resistant steel plate 241 is uniform, and after the first wear-resistant steel plate 241 is laid on the material guiding bottom surface, the surface of the first wear-resistant steel plate 241 away from the material guiding bottom surface also forms an angle θ with the horizontal plane. The length of the first wear-resistant steel plate 241 extends along the inclined direction of the material guiding bottom surface, and the width of the first wear-resistant steel plate 241 extends in the left-right direction.
[0044] In the embodiment, as shown in Figure 4 and Figure 5As shown, the embedded part on the material guiding bottom surface is a first embedded part 230, which includes a first steel member 231 and a second steel member 232. The material guiding bottom surface is provided with a first installation groove, which is adaptively connected with the first steel member 231. In the pouring and forming work of the chute main body, the first steel member 231 is pre-embedded in the chute main body, so that the first installation groove is formed after the chute main body is formed. The first steel member 231 is flush with the material guiding bottom surface of the chute main body.
[0045] The second steel member 232 is fixedly connected with the first steel member 231 by welding. Specifically, the surface of the first steel member 231 opposite to the second steel member 232 is larger than the surface of the second steel member 232 opposite to the first steel member 231. The second steel member 232 is located at the central position of the first steel member 231, and the first steel member 231 is welded with the second steel member 232 by fillet welding. In this embodiment, the first steel member 231 and the second steel member 232 are both square plates.
[0046] The first wear-resistant steel plate 241 is provided with a plug welding hole 233, which penetrates through the thickness direction of the first wear-resistant steel plate 241. After the second steel member 232 is connected with the first steel member 231, the second steel member 232 is placed in the plug welding hole 233 of the first wear-resistant steel plate 241, and then the second steel member 232 is fixedly connected with the first wear-resistant steel plate 241 by welding. At this time, an annular weld 234 is arranged between the outer circumferential surface of the second steel member 232 and the inner circumferential surface of the plug welding hole 233. It can be understood that the first wear-resistant steel plate 241 can be one piece, or can be connected into one piece by welding a plurality of wear-resistant steel plates. In this way, the welding strength between the second steel member 232 and the first wear-resistant steel plate 241 can be enhanced, so that the second steel member 232 and the first wear-resistant steel plate 241 are not easy to separate.
[0047] The second wear-resistant steel plate 242 is provided with two pieces, and the two pieces of the second wear-resistant steel plate 242 cover the material guiding side surfaces on both sides of the material guiding bottom surface respectively. The first wear-resistant steel plate 241 is welded with the second wear-resistant steel plate 242 on both sides of the material guiding bottom surface. Specifically, the second wear-resistant steel plate 242 and the first wear-resistant steel plate 241 are arranged perpendicularly to each other, and they are welded by fillet welding.
[0048] The second wear-resistant steel plate 242 is welded and connected with the embedded part on the material guiding side surface, so that the second wear-resistant steel plate 242 is fixed on the material guiding side surface. The thickness of the second wear-resistant steel plate 242 is consistent, and the upper side long edge of the second wear-resistant steel plate 242 also forms an angle θ with the horizontal direction after the second wear-resistant steel plate 242 is laid on the material guiding side surface. The length of the second wear-resistant steel plate 242 also extends along the inclined direction of the material guiding bottom surface. The second wear-resistant steel plate 242 can be trapezoidal.
[0049] In the embodiment, the embedded part on the material guiding side is the second embedded part 250, which extends along the length direction of the second wear-resistant steel plate 242. The material guiding side is provided with a second mounting groove, which is adaptively connected with the second embedded part 250. During the pouring and forming of the chute main body, the second embedded part 250 is embedded in the chute main body in advance, so that the second mounting groove is formed after the chute main body is formed. The second embedded part 250 is flush with the material guiding side of the chute main body. The second wear-resistant steel plate 242 is arranged in close contact with the second embedded part 250, and the upper side long edge of the second wear-resistant steel plate 242 is welded with the second embedded part 250. It can be understood that the second wear-resistant steel plate 242 can be one piece, or can be connected as a whole by welding a plurality of wear-resistant steel plates.
[0050] Of course, it is not excluded that in other embodiments, the embedded part on the material guiding side is the first embedded part 230, which is plug welding connected with the second wear-resistant steel plate 242. Specifically, the second wear-resistant steel plate 242 can also be provided with a plug welding hole 233, and the first embedded part 230 on the material guiding side is located in the plug welding hole 233 and is fixedly connected with the annular weld 234 in the plug welding hole 233. In addition, the first embedded part 230 and the second embedded part 250 can be provided on the material guiding side at the same time, and the first embedded part 230 and the second embedded part 250 are fixedly connected with the second wear-resistant steel plate 242.
[0051] It can be understood that the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 are composed of a low-carbon steel or low-alloy steel substrate and a high-hardness alloy wear-resistant layer, wherein the substrate provides impact resistance and toughness, and the wear-resistant layer is responsible for resisting wear. The thickness of the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 can be selected according to the actual design situation.
[0052] The surface of the second wear-resistant steel plate 242 away from the material guiding side is provided with a corrosion-resistant and wear-resistant composite coating, and the surface of the first wear-resistant steel plate 241 away from the material guiding bottom is also provided with a corrosion-resistant and wear-resistant composite coating. It can be understood that the corrosion-resistant and wear-resistant composite coating is a surface protection technology that has corrosion resistance and wear resistance by multi-layer material compounding or functional modification. The corrosion-resistant and wear-resistant composite coating can be made of existing materials, such as polyurea-based composite coating, silicon carbide / ceramic composite coating or epoxy-based composite coating, etc. After the welding work of the first wear-resistant steel plate 241 and the welding work of the second wear-resistant steel plate 242 are completed, the weld is polished flat, and the surface rust is removed, and then the corrosion-resistant and wear-resistant composite coating is brushed.
[0053] In some embodiments, the chute main body is a waterproof concrete structure. Preferably, the chute main body is a waterproof and anti-crack concrete layer structure.
[0054] Specifically, the bottom wall 221 and the side wall 222 of the chute body are integrally cast with impermeable concrete. The impermeable concrete is a kind of concrete with high impermeability, which can effectively resist the penetration of water and harmful media. The chute body is made of waterproof concrete, and the strength thereof can be determined according to the concrete grade required by the structural design. Moreover, on this basis, micro-expansion anti-cracking agent and engineering anti-cracking fibers (such as organic wear-resistant fibers or metal fibers) can be added to the concrete to improve the inherent compactness, impermeability and crack resistance of the concrete.
[0055] In some embodiments, as shown in Figure 2 and Figure 3 , the first wear-resistant steel plate 241 is arranged in close contact with the material guiding bottom surface, and they are bonded by glue. The second wear-resistant steel plate 242 is arranged in close contact with the material guiding side surface, and they are bonded by glue.
[0056] The structural adhesive is a high-performance adhesive for stressed structural members, which has excellent mechanical properties and durability.
[0057] On the basis of the welding installation of the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242, not only the first wear-resistant steel plate 241 is in close contact with the material guiding bottom surface, and the second wear-resistant steel plate 242 is in close contact with the material guiding side surface, but also structural adhesive is added at the contact between them, which can enhance the connection effect between the first wear-resistant steel plate 241 and the material guiding bottom surface and the connection effect between the second wear-resistant steel plate 242 and the material guiding side surface, so that the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 can be stably fixed on the chute body, and the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 are not prone to warping deformation.
[0058] In some embodiments, as shown in Figure 2 and Figure 3 , the chute body has an upper end inlet and a lower end outlet. The upper end inlet is the feeding port, and the lower end outlet is the discharging port. A first protrusion is arranged at the upper end inlet, which protrudes vertically upward. Meanwhile, a second protrusion is arranged at the lower end outlet, which protrudes vertically downward. Moreover, the first protrusion and the second protrusion are both provided with a third embedded part 260. The third embedded part 260 is made of weather-resistant steel or stainless steel.
[0059] The upper short side of the first wear-resistant steel plate 241 is welded with the third embedded part 260 on the first protrusion, and the lower short side of the first wear-resistant steel plate 241 is welded with the third embedded part 260 on the second protrusion. It can be understood that when the feeding chute structure 200 is applied to a garbage pool, the anti-collision threshold 210 of the garbage pool can be used as the first protrusion, and the concrete hidden beam 273 below the feeding chute structure 200 of the garbage pool can be used as the second protrusion, and the anti-collision threshold 210 and the concrete hidden beam 273 are both pre-embedded with the third embedded part 260. The width of the third embedded part 260 extends in the up-down direction, and the length of the third embedded part 260 extends in the left-right direction.
[0060] Due to the welding between the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242, the upper and lower sides of the first wear-resistant steel plate 241 are welded with the third embedded parts 260 on the upper and lower sides, respectively, and the upper long side of the second wear-resistant steel plate 242 is welded with the second embedded part 250, so that a closed system can be formed, and the area of the feeding chute structure 200 in contact with corrosive materials such as garbage is completely covered by the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242, avoiding the chute body from being easily corroded by contacting with corrosive materials.
[0061] If the third embedded part 260 is not provided, the length of the first wear-resistant steel plate 241 needs to be designed to be long enough to avoid corrosive liquid from flowing into the chute body from the gap between the upper end of the first wear-resistant steel plate 241 and the guide bottom surface. If the second embedded part 250 is not provided, the width of the second wear-resistant steel plate 242 needs to be designed to be long enough to avoid corrosive liquid from flowing into the chute body from the gap between the upper long side of the second wear-resistant steel plate 242 and the guide side surface.
[0062] In the feeding chute structure 200 provided in the above embodiment, not only the anticorrosive coating is arranged on the guide bottom surface and the guide side surface of the chute body, but also the first wear-resistant steel plate 241 is covered on the guide bottom surface of the chute body, the second wear-resistant steel plate 242 is covered on the guide side surface of the chute body, and the anticorrosive wear-resistant composite coating is arranged on the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242, so that the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 can be effectively protected by the anticorrosive wear-resistant composite coating, and the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 are prevented from being easily corroded and worn, and the chute body is effectively protected by the first wear-resistant steel plate 241, the second wear-resistant steel plate 242 and the anticorrosive coating, so that the chute body of the concrete structure is prevented from being easily corroded and worn, thereby improving the wear resistance and the corrosion resistance of the feeding chute structure 200 by establishing multiple protection lines; and the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 are installed on the chute body by the embedded parts, and the first wear-resistant steel plate 241 is welded with the second wear-resistant steel plate 242, so that the construction convenience and the installation quality of the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 can be ensured.
[0063] When the feeding chute structure 200 is manufactured at the garbage pool, the chute body is integrally poured by the anti-permeation concrete, the micro-expansion anti-cracking agent and the engineering anti-cracking fiber are mixed in the concrete, the guide bottom surface of the chute body is arranged as an inclined surface with an acute angle of 55° to 60° with the horizontal line, the first steel member 231 and the second embedded part 250 are pre-embedded in the chute body, the first steel member 231 is a 200*200 embedded part, and the second embedded part 250 is a 100-wide full-length embedded part. In addition, the third embedded part 260 can be pre-embedded in the anti-collision threshold 210 located on the upper side of the chute body and the concrete hidden beam 273 located on the lower side of the chute body. The third embedded part 260 is a 100-wide full-length embedded part. When the anti-permeation concrete reaches the strength and is removed, the surface of the anti-permeation concrete can be polished.
[0064] According to the size of the completed chute body, the inner surface size of the chute body is reviewed and measured, the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 are pre-manufactured according to the size, the position of the embedded part is marked on the first wear-resistant steel plate 241, the 100*100 second steel member 232 is cut at the position of the embedded part, and the plug welding hole 233 is manufactured at the position of the embedded part of the first wear-resistant steel plate 241. In this way, the waste material can be effectively utilized when the plug welding hole 233 is manufactured on the first wear-resistant steel plate 241. Then, the cut second steel member 232 is welded to the first steel member 231 pre-embedded on the chute body by using the fillet weld according to the lofting position of the first wear-resistant steel plate 241.
[0065] After the anti-permeation concrete is polished, a layer of corrosion-proof coating is first applied on the guide bottom surface and the guide side surface, and after the strength is reached, a layer of structural bonding glue is applied. Then, the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 are placed on the guide bottom surface and the guide side surface of the chute body in turn according to the lofting position. After the first wear-resistant steel plate 241 is attached to the guide bottom surface, the plug welding hole 233 of the first wear-resistant steel plate 241 is aligned with the second steel member 232 which has been welded, and the second steel member 232 and the first wear-resistant steel plate 241 are welded into one body by plug welding. If the first wear-resistant steel plate 241 is spliced by multiple wear-resistant steel plates, after each wear-resistant steel plate is welded, the welding work of the joint of the spliced wear-resistant steel plates is performed.
[0066] After the first wear-resistant steel plate 241 is welded, the second wear-resistant steel plate 242 is pasted and welded. Specifically, the vertical intersection between the second wear-resistant steel plate 242 and the first wear-resistant steel plate 241 is welded by using an angle weld. The upper long side edge of the second wear-resistant steel plate 242 is welded with the second embedded member 250. Subsequently, the upper short side edge of the first wear-resistant steel plate 241 is welded with the third embedded member 260 embedded at the anti-collision door sill 210, and the lower short side edge of the first wear-resistant steel plate 241 is welded with the third embedded member 260 embedded at the concrete hidden beam 273. After the welding work of the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 is completed, a closed system can be formed, which ensures that the area of the feed chute structure 200 in contact with the garbage is completely covered by the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242.
[0067] After welding is completed, the weld is polished to be flat, and surface rust is removed, and finally a layer of corrosion-resistant wear-resistant composite coating is applied on the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242.
[0068] In the feed chute structure 200 of the above embodiment, the self-corrosion-resistant wear-resistant layer of the waterproof anti-cracking concrete layer structure, the corrosion-proof coating on the concrete surface, the externally attached corrosion-resistant wear-resistant plate material (such as the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 which both have corrosion-resistant wear-resistant composite coating), and the like are combined, and the related component laying construction process is optimized, so as to achieve the effects of convenient construction, reliable quality, long wear resistance and corrosion resistance.
[0069] As shown in Figures 1 to 5 As shown in FIG. 6, the garbage pool according to the second aspect of the present application comprises a garbage pool body and the feed chute structure 200 according to the first aspect of the present application. The garbage pool body has a garbage inlet, and the feed chute structure 200 is arranged at the garbage inlet. The discharge port of the feed chute structure 200 is opposite and communicates with the garbage inlet, so that the garbage can enter the garbage pool along the guide direction of the feed chute structure 200.
[0070] In the garbage pool of the embodiment, since the feeding chute structure 200 is provided at the entrance of the garbage pool, all areas of the feeding chute structure 200 that are in long-term contact with garbage are covered by the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242. Therefore, the multi-line defense formed by the anticorrosive wear-resistant composite coating, the first wear-resistant steel plate 241, the second wear-resistant steel plate 242, and the anticorrosive coating can be used to ensure that the chute body is not easily corroded and worn, thereby reducing the repair frequency of the feeding chute structure 200, allowing the garbage to be continuously and smoothly fed into the garbage pool, and ensuring the continuous operation of the garbage incineration power plant.
[0071] When the feeding chute structure 200 of the above embodiment is the only entrance for feeding garbage into the garbage pool in a garbage power plant, the feeding chute structure 200 is where all garbage passes through. By designing a reasonable angle of the feeding chute structure 200, it can be ensured that the garbage can smoothly come out of the garbage truck 100 by its own weight and fall into the garbage pool through the feeding chute structure 200, ensuring that the garbage will not block the feeding port of the feeding chute structure 200, thereby ensuring that the garbage truck 100 can dump garbage smoothly and effectively prevent the garbage truck 100 from overturning.
[0072] The feeding chute structure 200 can be supported by concrete frame columns 271, concrete beams 272, and concrete hidden beams 273, etc. As shown in Figure 1 The feeding chute structure 200 is provided with a crash threshold 210 and a discharge platform 300 at the front side. When the garbage truck 100 moves backward to the right position on the discharge platform 300, the garbage is dropped from the garbage truck 100 into the feeding chute structure 200 and transferred to the garbage pool through the feeding chute structure 200 by dumping garbage from the garbage truck 100.
[0073] The anticorrosive coating, the first wear-resistant steel plate 241, the second wear-resistant steel plate 242, and the anticorrosive wear-resistant composite coating are added at the area where the chute body is in high-frequency contact with garbage, and the bonding surface between them is smooth. In addition, considering the convenience and accuracy of construction, the pre-embedded welding method and the glue bonding method are used in the installation of the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 to ensure the durability of the feeding chute structure 200 in long-term operation.
[0074] In the waste incineration power generation project, the feeding chute structure 200 adopts a concrete structure as a support stress component base layer, C40 concrete is used in pouring forming, and micro-expansion anti-cracking agent and engineering fibers are mixed. The first embedded part 230, the second embedded part 250 and the third embedded part 260 can all use 316L stainless steel plates, and the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 can also use 316L stainless steel plates. After the surface of the concrete structure is polished flat, a permeable crystalline anticorrosive coating is sprayed on the surface to form an anticorrosive coating. At this time, the permeable crystalline anticorrosive coating can effectively prevent liquid from penetrating into the interior of the concrete structure through chemical reaction to protect the steel bars inside the concrete structure. The structural adhesive glue is a grade A structural reinforcement glue, which is used to bond the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 to the chute body respectively. The first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 are constructed according to the structural reinforcement requirements to ensure the construction quality.
[0075] By determining a reasonable inclination angle of the chute body, it can be ensured that the garbage automatically slides into the garbage pool by gravity and the abrasion is minimized. By setting a reasonable construction sequence, the operability of the concrete structure pouring, the first wear-resistant steel plate 241 and the second wear-resistant steel plate 242 installation is ensured in a simple construction manner, thereby ensuring the construction and installation quality. Moreover, multiple lines of defense are adopted for corrosion and wear protection, through the protection of the corrosion and wear resistant composite coating on the wear-resistant steel plate surface, the wear-resistant steel plate allowance protection, the corrosion resistant coating on the concrete structure surface protection, and the concrete structure itself compactness and impermeability protection, realizing all-round wear and corrosion resistant treatment.
[0076] It can be understood that the concrete structure pouring construction, surface coating treatment, embedding of the embedded part and installation of the wear-resistant steel plate of the feeding chute structure 200 are relatively convenient, which ensures the construction quality. After the garbage enters the feeding chute structure 200, the corrosion and wear resistant composite coating on the surface of the wear-resistant steel plate can effectively protect the wear-resistant steel plate, and all areas in the chute body that are in long-term contact with the garbage are covered by the wear-resistant steel plate, and the wear-resistant steel plate itself considers the corrosion allowance, which can effectively protect the concrete structure from corrosion. Even if there are local construction defects, the corrosion resistant coating on the concrete structure surface and the impermeability of the concrete structure itself can resist long-term corrosion in the garbage leachate environment, effectively ensuring that the feeding chute structure 200 does not need to be repaired during the entire service life of the waste power plant, and ensuring smooth garbage feeding.
[0077] Therefore, the garbage pool of the embodiment adopts the feeding chute structure 200 of the above embodiment, and can avoid corrosion of corrosive liquid such as garbage leachate to the concrete structure through the cooperation between the embedded part and the wear-resistant steel plate, so as to ensure good wear resistance of the concrete structure surface layer. Through the setting of multiple defense lines, the possibility of local corrosion damage of the concrete structure caused by local defects can be greatly reduced, and then gradually expanded to the entire area.
[0078] In addition, a pre-assembled construction scheme can also be set, so as to ensure clear construction sequence and simple construction scheme, thereby ensuring construction quality. Furthermore, different material constructions can be selected according to user requirements and material corrosion conditions, and reasonable treatment methods with different costs are provided.
