[0002] Currently, waste incinerators with fixed grate installations have significant drawbacks in practical applications.
[0003] When there is a lot of ash, it can easily clog the grate holes, resulting in poor ventilation. Therefore, regular cleaning is required, which is a short cleaning cycle and consumes a lot of manpower. Utility Model Content
[0004] The purpose of this invention is to provide a synchronous rotating grate device, which can effectively solve the problems in the background art.
[0005] The technical solution to achieve the above objective is: a synchronous rotating grate device, comprising at least one row of grate bars arranged on the left and right, each row comprising at least one grate bar, characterized in that: the grate bars in the same row are connected as a whole by a drive shaft located in the middle, the two ends of the drive shaft are rotatably connected to the furnace body, one end of the drive shaft extends out of the furnace body and is connected to a grate bar rotation driver.
[0006] Furthermore, both ends of the drive shaft are rotatably connected to the furnace body via fixed sleeves.
[0007] Furthermore, one end of each drive shaft extends out of the furnace body, and the extended ends of the drive shafts are connected in a transmission manner. The grate bar rotation drive is connected in a transmission manner to one of the extended ends of the drive shaft.
[0008] Furthermore, the grate bars include a left grate bar body and a right grate bar body symmetrically connected on both sides of the drive shaft.
[0009] Furthermore, an air duct is connected to the extended end of the drive shaft, and a closed air-cooling cavity is formed between the air duct and the drive shaft. The air-cooling cavity is equipped with an air inlet and an air outlet.
[0010] Furthermore, two position detection sensors for position detection are provided on both sides of the extended end of one of the drive shafts.
[0011] Furthermore, the position detection sensor is a Hall position sensor, with two Hall position sensors offset by 180° around the drive shaft. A magnetic plate that cooperates with the Hall position sensor is fixed on the drive shaft. When the magnetic plate rotates to correspond to the position of one of the Hall position sensors, one side of the grate plate faces upward. When the magnetic plate rotates to correspond to the position of the other Hall position sensor, the other side of the grate plate faces upward.
[0012] The beneficial effects of this utility model are as follows: 1) This utility model uses a grate plate rotation driver to periodically drive the grate plates to rotate and discharge the accumulated ash into the slag hopper below, overcoming the technical problem of needing to manually clean the grate plates periodically in the prior art; 2) Each time the grate plates are driven to clean the accumulated ash, the grate plates rotate 180° to flip them over, so that the grate is heated evenly on both sides and deformation is reduced; 3) This utility model has simple internal installation and is easy to maintain; 4) The transmission structure has reduced requirements for installation accuracy and can better adapt to the use of the grate at certain temperatures. Attached Figure Description
[0013] Figure 1 This is a top view of the present invention;
[0014] Figure 2 This is a side view of the present invention. Detailed Implementation
[0015] like Figure 1 , 2 As shown, this utility model discloses a synchronous rotating grate device, including at least one row of grate bars 2 arranged left and right and set in the furnace body 1, each row including at least one grate bar 2, and the present utility model includes two grate bars 2 on the left and right sides.
[0016] The two grate bars 2 are connected as a whole by a drive shaft 3 located in the middle. The grate bar 2 includes a left grate bar body 2.1 and a right grate bar body 2.2 symmetrically connected to both sides of the drive shaft. The two ends of the drive shaft 3 are rotatably connected to the furnace body 1 through a fixing sleeve 4. The fixing sleeve 4 is made of high-temperature alloy, specifically, but not limited to, iron-based high-temperature alloy, nickel-based high-temperature alloy, etc. One end of the drive shaft 3 extends out of the furnace body 1 and is connected to a grate bar rotation driver 5. The grate bar rotation driver 5 is a reducer. One end of each drive shaft 3 extends out of the furnace body 1 and the extended ends are connected by chain and sprocket transmission. The grate bar rotation driver 5 is connected to the extended end of one of the drive shafts 3.
[0017] A duct 6 is connected to the extended end of the drive shaft 3. A closed air-cooled cavity 7 is formed between the duct 6 and the drive shaft 3. The air-cooled cavity 7 is provided with an air inlet and an air outlet.
[0018] Two position detection sensors 8 for position detection are provided on both sides of the extended end of one of the drive shafts 3. The position detection sensors 8 are Hall position sensors. The two Hall position sensors 8 are offset by 180° along the circumference of the drive shaft. A magnetic plate 9 that cooperates with the Hall position sensor 8 is fixed on the drive shaft 3. When the magnetic plate 9 rotates to correspond to the position of one of the Hall position sensors 8, one side of the grate plate 2 faces upward. When the magnetic plate 9 rotates to correspond to the position of the other Hall position sensor 8, the other side of the grate plate 2 faces upward.
[0019] The working process of this utility model:
[0020] The starting position of grate plate 2 is with side a facing upwards. Figure 2 As shown in the diagram, at this time, the magnetic plate 9 corresponds to the position of the Hall position sensor 8 on one side. When flipping, the grate plate 2 is driven to rotate synchronously by the grate plate rotation driver 5. After the grate plate 2 is rotated 90° by the grate plate rotation driver 5, the accumulated ash is discharged into the slag hopper below. After rotating 180°, the b side of the grate plate 2 faces upward, and the rotation driver 5 stops. At this time, the magnetic plate 9 corresponds to the position of the Hall position sensor 8 on the other side. The control of the grate plate rotation driver 5 is realized by the Hall position sensor 8. The above process is repeated every time ash is discharged, flipping the grate plate 2 so that the grate plate 2 is heated evenly on both sides and deformation is reduced.
