A grate module, a grate assembly and an incinerator

Abstract

This application discloses a grate module, grate assembly, and incinerator, comprising: a grate module body with positioning legs provided on the grate module body; and multiple grate support devices supported at different positions on the grate module body. Each grate support device is provided with a sliding expansion seat, and the positioning legs are slidably engaged with the sliding expansion seats. At least one of the sliding expansion seats is provided with a limiting guide rail to restrict the sliding of the positioning legs in a direction perpendicular to the waste conveying direction. This application slidably engages the positioning legs with the sliding expansion seats, meaning the positioning legs are not fixed to the sliding expansion seats but are floating on them. This allows the positioning legs to slide along the sliding expansion seats when the grate module body expands due to heat, preventing the risk of breakage at the connection point due to differences in temperature and expansion volume.

Description

Technical Field

[0001] This application relates to the field of incinerator technology, and more specifically, to a grate module, grate assembly and incinerator. Background Technology

[0002] With the continuous increase in municipal solid waste, mechanical grate incinerators, with their strong adaptability to waste and reliable operation, have gradually become the dominant type of municipal solid waste incineration.

[0003] Mechanical grate incinerators mainly consist of a drying section, a combustion section, and a burnout section along the waste conveying direction. As waste composition becomes increasingly complex and the calorific value of the waste increases, the incineration conditions become more complex. When dealing with waste with complex composition and high calorific value, the combustion temperature is high. During operation, the incinerator may experience thermal expansion under high temperatures, which could lead to the breakage of the incinerator's support points.

[0004] Therefore, how to avoid support point breakage and improve installation reliability is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0089] This application discloses a grate module to prevent support point breakage and improve installation reliability;

[0090] This application also discloses a grate assembly and an incinerator having the above-mentioned grate module.

[0091] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0092] like Figure 1 , Figure 2 and Figure 4 As shown in the illustration, the grate module disclosed in this application includes a grate module body 101 and a grate support device 103. The grate module body 101 is provided with positioning legs 1011, which serve as support points for the grate module body 101. Multiple positioning legs 1011 can be arranged around the center of gravity of the grate module body 101. For example, in this embodiment, four positioning legs 1011 are provided, that is, two rows of positioning legs 1011 are arranged back and forth along the waste conveying direction, with two legs in each row. It should be noted that the actual number of positioning legs 1011 can be arranged by those skilled in the art according to needs, and is not limited to four.

[0093] Multiple grate support devices 103 are provided, supporting different positions on the grate module body 101. Each grate support device 103 is equipped with a sliding expansion seat 102, and positioning legs 1011 are slidably engaged with the sliding expansion seat 102. The sliding expansion seats 102 and positioning legs 1011 are arranged in a one-to-one correspondence; that is, each positioning leg 1011 requires a corresponding sliding expansion seat 102 at its designated position. The positioning legs 1011 are supported on the sliding expansion seats 102, and at least in the waste conveying direction, the sliding expansion seats 102 do not constrain the positioning legs 1011. This allows the grate module body 101 to expand and deform along the waste conveying direction after heating, at which point the positioning legs 1011 slide along the sliding expansion seats 102, preventing breakage at the connection point due to the fixed connection between the positioning legs 1011 and the sliding expansion seats 102.

[0094] like Figure 5 and Figure 6 As shown, at least one sliding expansion seat 102 is provided with a limiting guide rail 104 to restrict the sliding of the positioning leg 1011 in a direction perpendicular to the waste conveying direction. The limiting guide rail 104 can restrict the sliding of the positioning leg 1011 in a direction perpendicular to the waste conveying direction, so that the expansion deformation of the grate module body 101 is completely offset in a direction parallel to the waste conveying direction, preventing the positioning leg 1011 from falling off the sliding expansion seat 102 due to excessive deformation in the direction perpendicular to the waste conveying direction.

[0095] Those skilled in the art will understand that each grate module body 101 is fixed in sequence, and the two ends of the grate assembly composed of each grate module body 101 usually need to be fixed. Therefore, there is no need to set a limiting guide rail to restrict the positioning leg 1011 from sliding in a direction parallel to the waste conveying direction, and it will not cause the grate module body 101 to detach from the sliding expansion seat 102.

[0096] Since the grate module bodies 101 are connected sequentially, it is sufficient to install a limiting guide rail 104 on only one sliding expansion seat 102 to constrain all grate module bodies 101. Of course, limiting guide rails 104 can also be installed on multiple sliding expansion seats 102, or even on all sliding expansion seats 102.

[0097] The grate module disclosed in this application has multiple positioning legs 1011 on the grate module body 101 and a sliding expansion seat 102 on the grate support device 103, with the positioning legs 1011 slidably engaged with the sliding expansion seat 102. That is, the positioning legs 1011 are not fixed to the sliding expansion seat 102, but are floatingly disposed on it. This allows the positioning legs 1011 to slide along the sliding expansion seat 102 when the grate module body 101 expands due to heat, preventing the risk of breakage at the connection due to different expansion volumes caused by temperature differences. A limiting guide rail 104 is provided on the sliding expansion seat 102, which restricts the sliding of the positioning legs 1011 in a direction perpendicular to the waste conveying direction, preventing the positioning legs 1011 from detaching from the sliding expansion seat 102 in this direction. Since the two ends of the grate assembly usually need to be fixed along the waste conveying direction, there is no need to provide a limiting device on the sliding expansion seat 102.

[0098] like Figures 5-8 As shown in a specific embodiment of this application, the sliding expansion seat 102 includes an expansion seat base 1021, an expansion seat connector 1022, and an expansion seat slide plate 1023. The expansion seat connector 1022 connects the expansion seat base 1021 and the expansion seat slide plate 1023. The expansion seat connector 1022 may have a plate-like structure, connecting the expansion seat base 1021 and the expansion seat slide plate 1023 to support the expansion seat slide plate 1023. The shape of the expansion seat connector 1022 can be used to set the expansion seat slide plate 1023 at a certain angle, which is adapted to the tilt angle of the grate, allowing the waste to move downstream under gravity. One or more expansion seat connectors 1022, supporting the expansion seat base 1021 and the expansion seat slide plate 1023, can be provided according to strength requirements.

[0099] The expansion seat base 1021 is fixed to the grate support device 103, and the positioning legs are slidably engaged with the expansion seat slide plate 1023. The expansion seat base 1021 can be fixed to the grate support device 103 by fasteners. Figure 2 As shown, the grate support device 103 may include support legs 1031 and support beams 1032, with the support beams 1032 supported by a plurality of support legs 1031. Figure 2 In the illustrated scheme, the support beam 1032 is supported by two support legs 1031. The upper surface of the support beam 1032 is flat, and the expansion seat base 1021 is fixed to the upper surface of the support beam 1032.

[0100] When a limiting guide rail 104 is provided on the sliding expansion seat 102, the limiting guide rail 104 is provided on the expansion seat slide plate 1023, and the limiting guide rail 104 and the expansion seat slide plate 1023 form a guide groove for the positioning leg to slide. For example, two limiting guide rails 104 arranged in parallel can be provided on the expansion seat slide plate 1023, and a guide groove is formed between the two limiting guide rails 104, and the positioning leg 1011 is provided in the guide groove.

[0101] For ease of understanding, the waste conveying direction is defined as the first direction, and the direction perpendicular to the waste conveying direction is defined as the second direction. Along the first direction, grate module body 101 is supported by grate support devices 103 at both ends; along the second direction, grate support devices 103 are provided with sliding expansion seats 102 at both ends, that is, each grate module body 101 is provided with four sliding expansion seats 102.

[0102] like Figure 2 and Figures 11-13 As shown, the grate module body 101 includes a grate frame, which includes an upper frame 301 and a lower frame housing 303 located below the upper frame 301. It should be noted that the upper frame 301 and the lower frame housing 303 are not different components, but rather refer to different parts of the grate module body 101.

[0103] A fixed grate beam 305 is supported on the upper frame 301, and grate blocks 214 are installed on the fixed grate beam 305. Since the fixed grate beam 305 is mounted on the upper frame 301 and therefore cannot move, the grate blocks 214 on the fixed grate beam 305 are stationary grate blocks. The fixed grate beam 305, while installing the grate blocks 214, also strengthens the structural strength of the grate frame.

[0104] Along the top-to-bottom direction, the cross-sectional area of ​​the lower frame housing 303 gradually decreases. That is, the lower frame housing 303 disclosed in this embodiment has a narrowing structure at the bottom. By narrowing the lower space of the lower frame housing 303, a larger space can be formed between two adjacent grate module bodies 101 in the narrowed area of ​​the lower frame housing 303. This space provides convenience for the maintenance of the drive cylinder 201, bearing seats, etc. Designing the lower frame housing 303 as a structure that gradually narrows from top to bottom can meet the combination requirements of multiple grate module bodies 101, creating sufficient maintenance space in the passageway between two adjacent grate module bodies 101, facilitating equipment maintenance. Furthermore, reserving maintenance space also forms a heat dissipation channel, preventing high temperature overheating between grate module bodies 101.

[0105] For ease of understanding, the plane containing the axes of each fixed grate beam 305 is defined as the reference plane. The angle between the side wall of the lower frame box 303 and the reference plane is θ, which is 40°-70° (including the endpoints). The narrowed portion of the lower frame box 303 can be a frustum pyramid structure with four opposing inclined surfaces. The angle between each inclined surface and the reference plane is θ, meaning the angle between each inclined surface and the reference plane can be selected between 40° and 70°, for example, 40°, 45°, 50°, 55°, 60°, 65°, 70°, etc. The angles between each inclined surface and the reference plane can be designed to be equal or different depending on the requirements. This embodiment does not limit the specific angles between each inclined surface and the reference plane.

[0106] like Figure 20 and Figure 21 As shown, the grate frame is equipped with frame reinforcing ribs, and the fixed grate beam 305 is equipped with fixed grate reinforcing ribs. Waste loads are transmitted through the fixed grate beam 305 and the movable grate beam 207. The load on the fixed grate beam 305 is transmitted to the positioning leg 1011 via the frame sidewalls and frame reinforcing ribs on the grate frame, and finally to the sliding expansion seat 102 by the positioning leg 1011. In this embodiment, frame reinforcing ribs and fixed grate reinforcing ribs are added to the force transmission path of the fixed grate beam 305 to improve its strength, prevent deformation of the corresponding stress-bearing parts, and extend the service life of the grate module body 101.

[0107] Furthermore, the frame reinforcing ribs may include a first frame reinforcing rib 306 arranged on the outer wall of the grate frame and a second frame reinforcing rib 307 arranged on the inner wall of the grate frame. That is, in this embodiment, frame reinforcing ribs are provided on both the inner and outer walls of the grate frame to facilitate force transmission. For example, the first frame reinforcing rib 306 may be located on the lower box 303 of the frame, but it is not excluded that the first frame reinforcing rib 306 may also be provided on the upper frame 301; correspondingly, the second frame reinforcing rib 307 is located on the upper frame 301, but it is not excluded that the second frame reinforcing rib 307 may also be provided on the lower box 303 of the frame.

[0108] In this embodiment, a second frame reinforcing rib 307 is provided on the inner side wall of the upper frame 301. The upper frame 301 is the area that supports the fixed grate beam 305. Therefore, by providing the second frame reinforcing rib 307 on the upper frame 301, the fixed grate reinforcing rib can be directly connected to the second frame reinforcing rib 307, thereby improving the strength of the connection between the fixed grate beam 305 and the grate frame and preventing deformation at the connection.

[0109] The garbage load acts on the fixed grate beam 305 through the grate block 214. The force of the fixed grate beam 305 acts on the upper frame 301 and the second frame reinforcement 307 of the upper frame 301 through itself and the fixed grate reinforcement, and continues to be transmitted downward to the lower box 303 of the frame and the first frame reinforcement 306 on the lower box 303 of the frame, and finally transmitted to the sliding expansion seat 102 by the positioning support leg 1011.

[0110] The fixed grate reinforcing ribs may include horizontal reinforcing ribs 3051, vertical reinforcing ribs 3053, and vertical beam reinforcing ribs 3052. The horizontal reinforcing ribs 3051 are parallel to and spaced apart from the fixed grate beams 305. The vertical reinforcing ribs 3053 connect the horizontal reinforcing ribs 3051 and the fixed grate beams 305. The surfaces of the horizontal reinforcing ribs 3051 and the vertical reinforcing ribs 3053 may be perpendicular.

[0111] The vertical beam reinforcing rib 3052 connects the horizontal plate reinforcing rib 3051, the fixed grate beam 305, and the vertical plate reinforcing rib 3053. The vertical beam reinforcing rib 3052 consists of multiple ribs spaced apart along the extension direction of the fixed grate beam 305.

[0112] It should be noted that the specific scheme for fixing grate reinforcing ribs disclosed in the above embodiments is only an example, and those skilled in the art can design specific structures for fixing grate reinforcing ribs according to their needs.

[0113] like Figure 3 As shown in a specific embodiment of this application, the grate module body 101 includes a moving grate assembly, and the driving source for the moving grate assembly is a drive cylinder 201. The drive cylinder 201 can be a hydraulic cylinder or other driving device, as long as it can drive the moving grate assembly to move.

[0114] like Figure 11 , Figure 14 and Figure 15 As shown, a mounting base 302 is fixed to the outer side of the grate frame. The drive cylinder 201 is hinged to the mounting base 302, and the mounting base 302 is located on the lower side of the lower housing 303 of the frame, so that the drive cylinder 201 is located in the narrowed area on the lower side of the lower housing 303. The narrowed area on the lower side of the lower housing 303 of the frame has a large space, which can provide installation space for the drive cylinder 201. The area where the drive cylinder 201 is located is on the lower side of the lower housing 303 of the frame, away from the combustion surface of the upper grate, avoiding excessively high ambient temperatures that could affect the lifespan of the drive cylinder 201.

[0115] like Figure 2 As shown, in the case where multiple grate modules are arranged along a direction perpendicular to the waste conveying direction, Figure 2In the illustrated scheme, four rows of grate modules are arranged along the direction perpendicular to the waste conveying direction, and at most one drive cylinder 201 is arranged between any two adjacent grate modules (meaning between any two adjacent grate modules along the direction perpendicular to the waste conveying direction).

[0116] by Figure 2 For example, the drive cylinders 201 of the two grate modules on the left are both arranged on the left side of the grate module, while the drive cylinders 201 of the two grate modules on the right are both arranged on the right side of the grate module. This arrangement ensures that the number of drive cylinders 201 between any two adjacent grate modules is at most one, and the number of drive cylinders 201 between the two grate modules in the middle is zero. Those skilled in the art can arrange the positions of the drive cylinders 201 on the grate modules according to their needs, as long as the number of drive cylinders 201 between two grate modules does not exceed one.

[0117] When a maximum of one drive cylinder 201 is set between two grate modules, it can be ensured that there is sufficient space in the area of ​​the lower box 303 of the frame between the two grate modules. Even if setting one drive cylinder 201 will occupy some space, the remaining space can still meet the needs of maintenance and heat dissipation.

[0118] like Figure 15 As shown, a diagonal brace 304 can be provided between the mounting base 302 and the grate frame. The diagonal brace 304 can increase the support strength of the mounting base 302, ensuring that when the drive cylinder 201 on the mounting base 302 outputs driving force, the mounting base 302 can provide sufficient support for the drive cylinder 201, preventing the mounting base 302 from deforming or breaking, and improving the reliability of the moving grate assembly when it operates.

[0119] In a specific embodiment of this application, each grate module is provided with only one drive cylinder 201, and the movable grate block assembly of the moving grate assembly is driven by a synchronization mechanism to ensure the synchronization of the movable grate block assembly when it moves.

[0120] like Figure 3 As shown, the movable grate block assembly includes two grate drive beams 209 that are slidably fitted within the grate frame, and a movable grate beam 207 supported on the two grate drive beams 209. A grate block 214 is provided on the movable grate beam 207. The grate block 214 provided on the movable grate beam 207 is a moving grate block, and the moving grate block and the stationary grate block are arranged alternately.

[0121] The two ends of the movable grate beam 207 are supported by two parallel grate drive beams 209. The drive cylinder 201 drives the two grate drive beams 209 to move synchronously through a synchronization mechanism. The drive cylinder 201 drives the synchronization mechanism to move, which in turn drives the two movable grate beams 207 to move synchronously, thereby driving the movable grate beams 207 and the movable grate blocks on the two movable grate beams 207 to move.

[0122] Compared to the existing technology, where each grate drive beam 209 is driven by a drive cylinder 201, and then the hydraulic control system is used to make the output actions of the two drive cylinders 201 consistent, so that the two grate drive beams 209 achieve synchronization, the actual synchronization is affected by the hydraulic system and the synchronization is poor.

[0123] In this embodiment, only one drive cylinder 201 is provided and arranged on one side of the grate module body 101. Then, through a synchronization mechanism, the power output by the drive cylinder 201 is synchronously transmitted to the two grate drive beams 209 to avoid inconsistent movement at both ends of the moving grate block, which would cause displacement during the movement and lead to deformation of the grate frame.

[0124] like Figure 3 As shown in a specific embodiment of this application, the synchronization mechanism may include a synchronization shaft 202, a hydraulic cylinder crank 215, and a crank-connecting rod mechanism. The synchronization shaft 202 is rotatably supported on the grate frame, the hydraulic cylinder crank 215 is fixed to the synchronization shaft 202, one end of the drive cylinder 201 is hinged to the mounting base 302, and the other end is hinged to the hydraulic cylinder crank 215 via a hydraulic cylinder pusher 216. After the piston rod of the drive cylinder 201 extends, it can drive the hydraulic cylinder crank 215 to rotate the synchronization shaft 202 in a first rotation direction. After the piston rod of the drive cylinder 201 retracts, it can drive the hydraulic cylinder crank 215 to rotate the synchronization shaft 202 in a second rotation direction.

[0125] The crank-connecting rod mechanism consists of two components, each corresponding to one of the two grate drive beams 209, and the two crank-connecting rod mechanisms have identical structures. Each crank-connecting rod mechanism includes a pusher crank 211 and a pusher body 212. The pusher crank 211 is fixed to the synchronous shaft 202, and one end of the pusher body 212 is hinged to the pusher crank 211, while the other end is hinged to the grate drive beam 209.

[0126] When the piston rod of the drive cylinder 201 extends, it drives the hydraulic cylinder crank 215 to rotate the synchronous shaft 202 in the first rotation direction. The synchronous shaft 202 drives the push rod crank 211 to rotate in the first rotation direction, and the push rod crank 211 pushes the push rod body 212 to swing, simultaneously causing the grate drive beam 209 to move to the right (i.e., causing the grate drive beam 209 to move in the forward direction of the waste conveying direction). When the piston rod of the drive cylinder 201 retracts, it drives the hydraulic cylinder crank 215 to rotate the synchronous shaft 202 in the second rotation direction. The synchronous shaft 202 drives the push rod crank 211 to rotate in the second rotation direction, and the push rod crank 211 pushes the push rod body 212 to swing, simultaneously causing the grate drive beam 209 to move to the left (i.e., causing the grate drive beam 209 to move in the backward direction of the waste conveying direction).

[0127] like Figure 2 , Figure 10 , Figures 17-19 As shown in a specific embodiment of this application, a fixed support 205 is provided inside the grate frame, a guide wheel device 206 is provided on the fixed support 205, and a first sliding plate 210 is provided on the grate drive beam 209. The guide wheel device 206 and the first sliding plate 210 are in rolling cooperation.

[0128] Along the direction of movement of the grate drive beam 209, i.e., at the front and rear positions of the grate frame, two sets of guide wheel devices 206 supported by fixed supports 205 are respectively installed. After being connected to the movable grate beam 207, the grate drive beam 209 sits on the guide wheel devices 206. When the grate drive beam 209 moves, the first sliding plate 210 fixed on the grate drive beam 209 moves along the guide wheel devices 206. The guide wheel devices 206 rotate with the movement of the first sliding plate 210, reducing friction and guiding the direction of movement of the grate drive beam 209.

[0129] like Figure 3 and Figure 10 As shown, a limiter 213 is installed inside the grate frame, and a second sliding plate 217 is installed on the grate drive beam 209 opposite to the limiter 213. The plate surface of the limiter 213 is parallel to the plate surface of the second sliding plate 217 and is spaced apart by a preset distance. The limiter 213 is located at the rear of the grate frame (i.e., upstream in the waste conveying direction) to prevent the grate drive beam 209 from tilting and colliding during its backward movement (i.e., when moving upstream in the waste conveying direction).

[0130] like Figures 17-19As shown, the guide wheel device 206 includes a guide wheel shaft 2062 supported on a fixed support 205 and a guide wheel 2061 rotatably mounted on the guide wheel shaft 2062. To improve the smoothness of the rotation of the guide wheel 2061, a bearing 2063 is provided between the guide wheel shaft 2062 and the guide wheel 2061. This bearing 2063 can be a self-lubricating bearing.

[0131] The guide wheel 2061 is provided with a limiting groove on its wheel surface, that is, a limiting groove is provided on the outer peripheral surface of the guide wheel 2061. The two side walls of the limiting groove can limit the first slide plate 210 to restrict the position of the first slide plate 210 in the axial direction of the guide wheel device 206.

[0132] The first slide plate 210 includes a slide plate base 2101 and a slide plate body 2102 disposed on the slide plate base 2101 and engaging with the limiting groove of the guide wheel 2061. The slide plate base 2101 is fixed to the grate drive beam 209. The slide plate body 2102 extends into the limiting groove, and the two side walls of the limiting groove can restrict the position of the slide plate body 2102 in the axial direction of the guide wheel 2061, so that the grate drive beam 209 can only move in a specific direction.

[0133] like Figure 9 As shown, the two ends of the synchronous shaft 202 are rotatably supported on the grate frame by bearing seats. The synchronous shaft 202 runs through both sides of the grate frame. A bearing seat 203 with a fixed end (i.e., the end with the drive cylinder 201) is provided on one side, and a bearing seat 204 with a free end (i.e., the end without the drive cylinder 201) is provided on the other side.

[0134] A sealing device 208 is provided at the junction of the grate frame and the synchronous shaft 202 to provide sealing protection. Figure 16 As shown, the sealing device 208 may include a sealing gasket 2081, packing 2083, and a gland 2082. The sealing gasket 2081 is fitted onto the synchronous shaft 202 and includes a first flange, a sleeve, and a sealing portion. The first flange is fixed to the grate frame, for example, to the lower housing 303 of the frame. The sleeve and sealing portion are fitted onto the synchronous shaft 202, forming a sealing space between the sleeve and the synchronous shaft 202.

[0135] The packing 2083 is disposed within the sealed space, and its first end is limited by a sealing portion. The gland 2082 includes a second flange portion and a limiting portion. The second flange portion is fixed to the first flange portion, and the limiting portion is inserted into the sealed space. The second end of the packing 2083 is limited by the limiting portion. The second flange portion can be fixed to the first flange portion with fasteners. To facilitate the connection between the first flange portion and the grate frame, a third flange portion 2084 is provided on the grate frame, and the first flange portion can be connected to the third flange portion 2084 with fasteners.

[0136] like Figure 22 and Figure 23 As shown in a specific embodiment of this application, the grate module body 101 includes a movable grate block assembly. The movable grate block assembly includes a grate drive beam 209 slidably fitted within the grate frame, and movable grate beams 207 supported on the grate drive beam 209. The movable grate beams 207 support the grate blocks 214. The grate drive beam 209 drives each movable grate beam 207 to move, thereby realizing the movement of the grate blocks 214 on the movable grate beams 207.

[0137] An anti-deviation roller device 218 is installed inside the grate frame, and the anti-deviation roller 2183 of the anti-deviation roller device 218 abuts against the grate drive beam 209. The anti-deviation roller device 218 is located on one side of the grate drive beam 209, so that the grate drive beam 209 always stays in contact with the anti-deviation roller 2183 when the grate drive beam 209 moves back and forth, preventing the grate drive beam 209 from deviating from its moving path and improving the safety of use.

[0138] The anti-deviation roller device 218 and the guide wheel device 206 are installed in different positions. The guide wheel device 206 is installed on the lower side of the grate drive beam 209 to support the grate drive beam 209. The anti-deviation roller device 218 is located on the outer side wall of the grate drive beam 209. The weight of the grate drive beam 209 does not act on the anti-deviation roller device 218. The anti-deviation roller device 218 only acts on the grate drive beam 209 when it deviates in a direction perpendicular to the direction of movement, preventing the grate drive beam 209 from deviating from the predetermined movement path.

[0139] The anti-deviation roller device 218 has a similar structure to the guide wheel device 206, including a mounting bracket 2181, a support base 2182, and an anti-deviation roller 2183. The support base 2182 is fixed to the mounting bracket 2181, and the anti-deviation roller 2183 is rotatably supported on the support base 2182 via an anti-deviation roller axle. To improve the smoothness of the rotation of the anti-deviation roller 2183, a bearing, which can be a self-lubricating bearing, is provided between the anti-deviation roller axle and the anti-deviation roller 2183. The mounting bracket 2181 is used to fix it to the grate frame, and to improve the reliability of the fixation, the mounting bracket 2181 may be equipped with reinforcing ribs.

[0140] like Figure 24As shown, the movable grate beam 207 may include a movable grate beam body 2071, an assembly 2072, and movable grate reinforcing ribs 2073. The movable grate beam body 2071 supports the grate block 214. The assembly 2072 is connected to the movable grate beam body 2071. The assembly 2072 can be welded to the movable grate beam body 2071 or designed as an integral structure with it. The assembly 2072 is used to connect to the grate drive beam 209. Specifically, the assembly 2072 can be connected to the grate drive beam 209 via fasteners, or it can be connected to the grate drive beam 209 in other ways.

[0141] The movable grate reinforcing rib 2073 is installed on the movable grate beam body 2071 and connected to the assembly 2072. The waste load is applied to the movable grate beam 207 through the grate block 214. The movable grate reinforcing rib 2073 on the movable grate beam 207 increases the strength of the movable grate beam 207, enabling it to withstand larger loads and preventing disturbance of the movable grate beam 207.

[0142] The force exerted by the movable grate beam 207 is transmitted through the grate drive beam 209 to the guide wheel device 206, then through the guide wheel device 206 to the lower frame housing 303 and the first frame reinforcing rib 306 on the lower frame housing 303, and finally transmitted to the sliding expansion seat 102 by the positioning support leg 1011. In this embodiment, the grate module, whether the fixed grate beam 305 or the movable grate beam 207, has a relatively reasonable force transmission path, and corresponding reinforcements have been made to the stress-bearing parts, thus improving the service life of the equipment.

[0143] This application also discloses a grate assembly, which includes at least one column of grate modules. Each column of grate modules includes multiple grate modules arranged along the waste conveying direction. The grate modules are those disclosed in the above embodiments. When there are multiple columns of grate modules, each column of grate modules is arranged perpendicular to the waste conveying direction.

[0144] This application discloses an incinerator that includes the grate assembly as described in the above embodiments. The incinerator disclosed in this application, having the aforementioned grate assembly, possesses all the technical effects of the grate assembly, which will not be elaborated upon further herein.
