Technical Field
[0001] This utility model relates to the technical field of grate seals for municipal solid waste incinerators, specifically a grate seal for municipal solid waste incinerators. Background Technology
[0002] Incinerators can be classified by the number of combustion chambers into single-chamber incinerators and multi-chamber incinerators. Based on the relationship between the direction of combustion gas and waste movement, incinerator bodies can be classified into co-current, counter-current, alternating current, and secondary flow types. Incinerators are commonly used for the harmless treatment of medical and domestic waste, as well as animal waste.
[0003] Currently, there are problems of ash leakage, coke leakage, and fire leakage at the grate connection of the stoker furnace in waste incinerator. During operation, a lot of ash, coke, and even unburned material fall into the air chamber, which can cause the air chamber to catch fire. In order to reduce the problem of coke falling and prevent ash and coke from leaking from the connection area of each grate, it is urgent to design a grate seal for municipal solid waste incinerator to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a grate seal for a municipal solid waste incinerator to solve the problems of ash leakage, coke leakage and fire leakage at the grate connection of the current waste incinerator stoker furnace mentioned in the background art. During operation, a lot of ash, coke and even unburned material fall into the air chamber, which leads to the air chamber igniting.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a grate sealing component for a municipal solid waste incinerator, comprising: a grate body, an ash-blocking mechanism at the bottom end of the grate body, a stabilizing mechanism at the bottom end of the grate body, the ash-blocking mechanism including a grate hole, the grate hole being opened inside the grate body, a connecting component fixed at the bottom end of the grate body, a fixed L-shaped seat fixedly connected to the bottom end of the grate body, an ash-blocking plate placed on the fixed L-shaped seat, a fixed plate fixedly connected to the bottom end of the ash-blocking plate, and a connecting plate fixedly connected to the bottom end of the fixed plate.
[0006] Preferably, a connecting block is fixedly connected to the left end of the connecting plate, the connecting block is inserted into the connecting groove, and the connecting groove is opened inside the connecting plate.
[0007] Preferably, the fixed L-shaped seat and the dust baffle are connected in an unfixed manner.
[0008] Preferably, the baffle plate is located below the grate hole, and the area of the baffle plate is larger than the maximum area inside the grate body where the grate hole is located.
[0009] Preferably, the stabilizing mechanism includes a support plate, which is fixedly connected to the bottom end of the grate body, and a fastening plate is fixedly connected to the side wall of the support plate.

[0022] A grate seal for a municipal solid waste incinerator includes: a grate body 111, an ash-blocking mechanism 2 at the bottom end of the grate body 111, a stabilizing mechanism 3 at the bottom end of the grate body 111, the ash-blocking mechanism 2 including a grate hole 211, the grate hole 211 being formed inside the grate body 111, a connecting component 212 fixedly attached to the bottom end of the grate body 111, a fixed L-shaped seat 213 fixedly connected to the bottom end of the grate body 111, an ash-blocking plate 214 placed on the fixed L-shaped seat 213, and the bottom end of the ash-blocking plate 214 being fixedly connected to... A fixing plate 215 is attached, and a connecting plate 216 is fixedly connected to the bottom end of the fixing plate 215. With this design, when using the grate seal of the municipal solid waste incinerator, if ash leakage occurs in the grate, an ash baffle plate 214 can be placed at its lower end and hung on the L-shaped structure of the fixed L-shaped seat 213. When ash leakage occurs in the grate, the ash and other impurities accumulate on the ash baffle plate 214, preventing a large amount of ash or even unburned material from falling into the air chamber and causing the air chamber to catch fire, thus avoiding a dangerous situation.
[0023] Furthermore, a connecting block 217 is fixedly connected to the left end of the connecting plate 216.

[0025] Furthermore, the baffle plate 214 is located below the grate hole 211, and the area of the baffle plate 214 is larger than the maximum area inside the grate body 111 where the grate hole 211 is located.
[0026] Furthermore, the stabilizing mechanism 3 includes a support plate 311, which is fixedly connected to the bottom end of the grate body 111. A fastening plate 312 is fixedly connected to the side wall of the support plate 311. The end of the fastening plate 312 away from the support plate 311 is fixedly connected to the outer wall of the connecting component 212. With this design, when using the grate seal for the municipal solid waste incinerator, the connecting component 212 at its bottom end is used to connect with the grate drive unit, making the grate more convenient to use.
[0027] Furthermore, four sets of connecting components 212 are provided. The connecting components 212 are symmetrically arranged along the central axis of the grate body 111. The connecting components 212 have a hollow structure. Through this design, the connecting components 212 are symmetrically arranged along the central axis of the grate body 111, which can maintain stability when the connecting components 212 are in use and improve their utilization.
[0028] Working principle:
[0029] When using the grate seal of this municipal solid waste incinerator, if ash leakage occurs during the use of the grate, an ash baffle 214 can be placed at its lower end and hung on the L-shaped structure of the fixed L-shaped seat 213. When ash leakage occurs, the ash and other impurities accumulate on the ash baffle 214, preventing a large amount of ash or even unburned material from falling into the air chamber and causing the air chamber to catch fire, thus avoiding a dangerous situation.
[0030] When using the grate seal for this municipal solid waste incinerator, the connecting part 212 at its bottom is used to connect with the grate drive unit, making the grate more convenient to use.
