The stationary disc 10 is located within the pyrolysis gasifier and is used to carry the materials, mainly various solid wastes, that are undergoing pyrolysis. After the materials are filled into the cracking gasification furnace, the materials fall onto the fixed disk 10 and undergo cracking reaction under certain conditions.

The slag pan 20 is located in the pyrolysis gasifier and at the bottom of the stationary pan 10. The slag pan 20 is used for bearing slag formed after cracking of materials. The bottom of the slag pan 20 is provided with a slag outlet, the materials are cracked to form slag and fall to the slag pan 20, and the slag is discharged through the slag outlet of the slag pan 20.

The driving mechanism 30 is located at the bottom of the pyrolysis gasifier and is used for driving the transmission mechanism 40. Alternatively, the drive mechanism 30 is a motor. Alternatively, in the present embodiment, the number of the driving mechanisms 30 is three; in other embodiments, the number of driving mechanisms 30 may be other values, such as two or four, according to actual needs.

The pyrolysis gasifier also comprises a plurality of supports 70, and the number of the supports 70 is the same as that of the driving mechanisms 30. All the drive mechanisms 30 are fixed to the holder 70 in a one-to-one correspondence, respectively. For example, in the present embodiment, the number of the driving mechanisms 30 is three, the number of the supports 70 is also three, and each driving mechanism 30 is respectively mounted on one of the supports 70.

The number of the transmission mechanisms 40 is the same as that of the driving mechanisms 30, and all the driving mechanisms 30 are respectively connected with and drive the transmission mechanisms 40 in a one-to-one correspondence. Alternatively, in the present embodiment, the transmission mechanisms 40 are transmission sprocket pairs, the number of the transmission mechanisms 40 is also three, and each transmission mechanism 40 is connected with one of the driving mechanisms 30 in a one-to-one correspondence manner. In other embodiments, the number of the transmission mechanisms 40 is different according to the number of the driving mechanisms 30, for example, the number of the transmission mechanisms 40 is two or four; the transmission mechanism 40 may be another transmission mechanism such as a gear pair.

The number of drive shafts 50 corresponds to the number of transmission mechanisms 40. It will be appreciated that the number of drive shafts 50 and the number of drive mechanisms 30 are also consistent. All of the drive shafts 50 are coaxially connected together by conical bearings in such a manner that one of the drive shafts 50 is nested in the outer periphery of the other drive shaft 50. All the drive shafts 50 are coaxially nested together and thus correspond to a shaft which is entirely formed and erected at the center of the pyrolysis gasifier. All the driving shafts 50 are integrated and have three mounting positions in total, and the three mounting positions are arranged in the pyrolysis gasifier from high to low in sequence; that is, the first installation position is near the charge inlet at the top of the pyrolysis gasifier, and the third installation position is near the bottom of the pyrolysis gasifier. All of the transmission mechanisms 40 are connected to the drive shafts 50 in a one-to-one correspondence to drive the different drive shafts 50 to rotate at different speeds.

As shown in fig. 1, in the present embodiment, the number of the driving shafts 50 is three, wherein the first driving shaft 50 is connected to the second driving shaft 50 through a conical bearing, and the second driving shaft 50 is sleeved on the outer circumference of the first driving shaft 50, so that the first driving shaft 50 and the second driving shaft 50 can realize differential rotation on the coaxial basis. Similarly, the second driving shaft 50 is connected to the third driving shaft 50 through a conical bearing, and the third driving shaft 50 is nested in the outer periphery of the second driving shaft 50, so that the second driving shaft 50 and the third driving shaft 50 realize differential rotation on a coaxial basis. It will be appreciated that the rotational speed of any two of the first drive shaft 50, the second drive shaft 50, and the third drive shaft 50 may be different. The three drive shafts 50 correspond to three mounting positions one by one, that is, each drive shaft 50 has one mounting position. Each of the driving shafts 50 is connected to one of the transmission mechanisms 40 in a one-to-one correspondence, and each of the transmission mechanisms 40 is connected to one of the driving mechanisms 30, so that the rotation speed of each of the driving shafts 50 is controlled by the corresponding one of the transmission mechanisms 40 and the corresponding one of the driving mechanisms 30, that is, the rotation speeds of the three driving shafts 50 are individually controlled, and the three driving shafts 50 can realize differential rotation.

In other embodiments, the number of drive shafts 50 can be other numbers, such as two or four, as desired, and all of the drive shafts 50 can be coaxially nested in the manner described above. When the number of the drive shafts 50 is two, one of the drive shafts 50 may have two mounting positions, that is, two mounting positions among three are located at the same drive shaft 50.

The turning wheel 60 is mounted to the driving shaft 50 and turns with the driving shaft 50. When the number of the rotary wheels 60 is one, the rotary wheel 50 is mounted to one of the drive shafts 50 and is located at only any one of the three mounting positions according to actual needs. When the number of the rotating wheels 60 is plural, each rotating wheel 60 is mounted on one of the driving shafts 50, and all the rotating wheels 60 are distributed at one or more mounting positions; that is, only one or two of the mounting locations may have the rotatable wheel 60 mounted thereto, or three mounting locations may have the rotatable wheel 60 mounted thereto. The driving shafts 50 respectively drive the corresponding rotating wheels 60 to rotate, i.e. when any one of the driving shafts 50 rotates, the corresponding rotating wheel 60 is driven to rotate. Since the different drive shafts 50 rotate at different speeds, the rotating wheels 60 mounted on the different drive shafts 50 have different speeds.

The rotary wheel 60 located at the first installation position rotates with the first driving shaft 50 and mixes the materials dropped into the fixed platter 10. In the second installation position, the rotating wheel 60 rotates along with the second driving shaft 50 and drives the slag on the fixed disk 10 to fall to the slag pan 20. The rotating wheel 60 at the third mounting position rotates with the third driving shaft 50 to sweep the slag on the slag pan 20 to the slag outlet of the slag pan 20, thereby discharging the slag.

For example, the number of the rotating wheels 60 is at least three, at least one rotating wheel 60 is installed on each driving shaft 50, and the three driving shafts 50 rotate at different speeds to drive the corresponding rotating wheels 60 to mix materials, drop slag and discharge slag respectively. Taking three rotating wheels 60 as an example, the three rotating wheels 60 are respectively installed on the three driving shafts 50 in a one-to-one correspondence manner, so that each driving shaft 50 has an installation position and is installed with one rotating wheel 60, the rotating speeds of the three rotating wheels 60 can be different from each other, and the first installation position is close to the material filling inlet at the top of the pyrolysis gasifier, so that the material enters the pyrolysis gasifier and then falls into the fixed disk 10 after being stirred by the rotating wheel 60 located at the first installation position. The materials are cracked on the fixed disc 10 and then are driven by the rotating wheel 60 at the second installation position to drop into the slag pan 20. And when the rotating wheel 60 at the third position rotates, the slag in the slag tray 20 can be swept to the slag outlet, so that slag can be discharged.

As shown in fig. 1, in the present embodiment, the number of the rotating wheels 60 is at least four, wherein two rotating wheels 60 are respectively installed at intervals on the same driving shaft 50 for stirring, that is, two rotating wheels 60 are installed at intervals on the first installation position of the first driving shaft 50. The other two drive shafts 50 are each fitted with at least one rotating wheel for slag dropping and tapping respectively. Before starting the pyrolysis reaction, the top of the pyrolysis gasifier is filled with materials, and the two rotating wheels 60 and the fixed disk 10 in the first installation position in the pyrolysis gasifier are used as main bearing structures of the materials. During the cracking process, the materials gradually fall into the fixed tray 10 while being uniformly mixed with the rotation of the two rotating wheels 60 located at the first installation position, and relatively speaking, the materials located at the top are gradually iterated downward after the materials located at the bottom are cracked.

Alternatively, the number of the rotating wheels 60 for tapping is plural and is arranged at intervals, so that the plural rotating wheels 60 can respectively sweep the slag at different positions in the slag pan 20 to the tap hole.

For another example, in another embodiment, the number of the driving mechanisms 30, the transmission mechanisms 40 and the driving shafts 50 is two, wherein one driving shaft 50 has two mounting positions, and at least two rotating wheels 60 are mounted on the same driving shaft 50 and respectively located at the two mounting positions of the driving shaft 50, so that the rotating wheels 60 located at the two mounting positions respectively achieve two different functions and are mounted on the same driving shaft 50 at the same rotating speed. For example, taking three rotating wheels 60 as an example, the rotating wheel 60 for stirring materials at the first mounting position and the rotating wheel 60 for dropping dregs at the second mounting position are both mounted on one of the driving shafts 50, and the rotating wheel 60 at the third mounting position is mounted on the other driving shaft 50. Of course, in other examples, the rotary wheel 60 for stirring and discharging slag may be mounted on the same drive shaft 50, or the rotary wheels 60 for discharging slag and discharging slag may be mounted on the same drive shaft 50.

In addition, in other embodiments, only one of the mounting locations may have a rotatable wheel 60 mounted thereto. For example, in the whole body in which two or three drive shafts 50 are coaxially connected together, one or more rotating wheels 60 for stirring are installed only at the first installation position, and the rotating wheel 60 for slag falling at the second installation position and the rotating wheel 60 for slag tapping at the third installation position are omitted. The three mounting positions correspond to three action functions respectively, and the rotating wheel 60 can be mounted at only one mounting position, so that only one action function is realized; the rotating wheel 60 may be installed at a plurality of installation positions, thereby realizing a combination corresponding to a plurality of functions. In short, as long as applied and realized the differential rotation through two, three or more coaxial links to each other of drive shaft 50 together to drive corresponding rotation wheel 60 and rotate and mix the material, the slag or this utility model concept of slagging tap in order to realize correspondingly, all belong to the utility model discloses a category.
