The present application discloses a grate device and a waste incinerator. The grate device comprises a grate driving mechanism (104) that reciprocally pushes out and retracts a movable grate (102). The grate driving mechanism (104) comprises a base (11) fixed to a machine frame (101) and a driving beam (111) linked to the movable grate (102). A driving oil cylinder (112) is provided on the base (11). An actuation end of the driving oil cylinder (112) is linkedly connected to a first hinge sleeve (121). A first hinge shaft (122) is rotatably inserted into the first hinge sleeve (121). The end of a driving rod (113) toward the driving oil cylinder (112) is linkedly connected to a second hinge sleeve (123). A second hinge shaft (124) is rotatably inserted into the second hinge sleeve (123). An adapter rod (125) is linkedly connected between the first hinge sleeve (121) and the second hinge sleeve (123). The axis of the first hinge shaft (122) and the axis of the second hinge shaft (124) are perpendicular to one another and are both perpendicular to the axis of the adapter rod (125), and the axis of one of the first hinge shaft (122) and the second hinge shaft (124) extends in a horizontal direction.

A cooled grate block as part of a grate for a system for thermally treating waste, including: a block body in the form of a cast part having an outer supporting face for the waste to be treated; a flat cavity situated directly below the supporting face, for receiving a cooling fluid; a fluid feed line and a fluid discharge line, which are connected to the cavity; at least one deflection element, which is arranged in the cavity to direct a cooling fluid within the cavity from the fluid feed line to the fluid discharge line; and a valve element situated in the end region of the cavity, for distributing the cooling fluid fed into the cavity through the fluid feed line.

This utility model discloses a reciprocating grate device with intermediate buffers, characterized in that: the grate device includes a multi-span grate body (1), an intermediate wall plate (2) is provided between adjacent grate bodies (1), and multiple intermediate buffers (3) are provided on the top of the intermediate wall plate (2). The intermediate buffer (3) includes an intermediate support block (4) fixedly connected to the intermediate wall plate (2). Buffer grooves (5) are respectively opened on both sides of the intermediate support block (4). A buffer plate (6) is movably connected in the buffer groove (5). Two through holes (7) are symmetrically opened on the intermediate support block (4). A spring (8) is provided in the through hole (7). A connecting end (9) is provided on the inner wall of the buffer plate (6). The buffer plate (6) is connected to the end of the spring (8) through the connecting end (9).

The utility model relates to a kind of sliding grate structure, belong to the technical field of biomass stove.The technical scheme is: movable grate cooperates with fixed grate, movable grate is inserted into the gap between adjacent fixed grate, relatively slide between adjacent grate during work, constitute sliding grate, the foremost end of fixed grate and movable grate is coke outlet platform.The utility model has beneficial effect: movable grate reciprocating linear motion along with the direction parallel to the length of fixed grate, keep the gap between fixed grate and movable grate uniform and permeable basically, facilitate ash and coke to fall, while guarantee primary air permeation, conducive to combustion and grate cooling;Rising on grate is in close contact with coking layer, break coke by reciprocating linear motion friction, as many as possible small coke particle is generated to fall and remove coke, the large coke block formed by exceeding breaking capacity is pushed out of grate to remove coke.

This utility model discloses an anti-wind-passing grate structure. A drive rod is provided on the outside of the furnace. One end of the drive rod is axially connected to the connecting plate of the adjacent air chamber, and the other end of the connecting plate is axially connected to the transmission rod. An external eccentric wheel is provided on the outside of the furnace cavity of the rotating shaft of each air chamber. The upper end of the external eccentric wheel at the outer end of the adjacent air chamber is axially connected to the connecting plate through the transmission rod. The advantage of this utility model is that, since the drive structure of the rotating shaft is located outside the furnace, unlike the push-pull rod of a traditional boiler that longitudinally passes through multiple air chamber partitions, it will not cause wind-passing.

A kind of cold ash bucket structure and arrangement method of pulverized coal boiler with combustion grate.The boiler is directly dropped into cold ash bucket and slag well after combustion, and combustion grate needs to be installed at cold ash bucket for combustion, and cold ash bucket water-cooled wall needs special design structure to cooperate with grate to realize.The application comprises:combustion chamber water-cooled wall (1), combustion chamber water-cooled wall is a vertical water-cooled wall added below spiral water-cooled wall after cold ash bucket is closed, to form space for installing grate (2), grate beam (11) is installed below grate, grate is connected with water-cooled wall lower header (6) through support beam (10), water-cooled wall lower header is in the form of frame structure, its bottom is connected with ash bucket (9) through T type prewelding piece (8), grate is symmetrically arranged on both sides of furnace center line, slag well (7) is installed at middle position, combustion chamber center tube screen (3) is installed above slag well.The application is used for cold ash bucket structure of pulverized coal boiler with combustion grate.
