[0002] Cracking is the reaction process of decomposition of matter by heating. Many inorganic substances and organic substances will decompose when heated to a certain extent. Due to the factors of improving pyrolysis efficiency, improving pyrolysis product yield, preparing products not easy to prepare by conventional pyrolysis, etc., more and more researches on catalytic pyrolysis by adding catalysts in the pyrolysis process are carried out. Some catalytic pyrolysis processes such as adding CaO, MgO and other catalysts in plastic pyrolysis have been used in industrial production.

[0003] The innovation of solid waste cracking technology lies in that it can decompose complex organic compounds in waste into simple molecules such as fuel oil, carbon black and synthetic gas. This process not only reduces the volume of waste, but more importantly, it converts it into resources with economic value.

[0004] Solid waste cracking generally adopts cracking furnace for cracking treatment. Since ash will be generated in the furnace body after cracking, it is necessary to discharge the ash after a period of cracking. The existing discharge treatment needs to use an auger to discharge the ash or stop the machine first and then discharge the ash with the help of other auxiliary tools, which is inconvenient to operate and affects the treatment efficiency.

[0009] A guide part is fixed on the inner wall of the furnace body. A spiral pushing plate arranged in the furnace body can convey the ash to the discharge part through the guide part when the furnace body rotates.

[0010] When the first furnace door is closed, the discharge part moves and makes the communication position butt joint with the guide part.

In some examples, methods, means, elements well known to those skilled in the art are not described in detail, in order to highlight the main idea of the present application.

[0028] A slag discharge device of a solid waste pyrolysis equipment supporting arm furnace door is arranged in a pyrolysis furnace, the pyrolysis furnace comprises a furnace body 1 and a first furnace door 3, a through slot is formed on the first furnace door 3 and is blocked by a second furnace door 6, wherein it is necessary to note that a connection frame 4 is fixed on the first furnace door 3, the connection frame 4 is hinged with the furnace body 1, and the first furnace door 3 can also be fixed with the furnace body 1 through a first locking part 5 to realize the sealing of the furnace body 1, and the second furnace door 6 is locked with the first furnace door 3 through a second locking part 7 to realize the sealing of the through slot.

[0029] The first locking part 5 and the second locking part 7 described above both comprise a screw rod and a nut, which are common locking means in the technical field, therefore, this embodiment will not be described in detail.

[0030] Please refer to Figures 1-4The utility model discloses a slagging-off device, which comprises a first furnace door, a furnace body, a second furnace door, a spiral pushing plate, a guide piece and a discharging piece.

[0031] In the embodiment, when slagging-off is needed, the second furnace door 6 is opened to make the through slot in a conducting state, and the furnace body 1 is kept in a continuous rotating state. When the furnace body 1 rotates, the spiral pushing plate 13 is driven to rotate. The ash and slag in the furnace body 1 moves to the guide piece under the action of the spiral pushing plate 13, and then moves to the discharging piece 8 through the guide piece. Finally, the ash and slag is discharged through the through slot. The discharged ash and slag can be collected by a shovel or the like.

[0032] The slagging-off device provided by the embodiment can ensure that the furnace body 1 is continuously in a rotating state, and at the same time, continuous feeding is carried out at the other end of the furnace body 1, so that continuous operation of the cracking furnace is realized, and slagging-off is not needed during shutdown, thereby effectively improving the cracking efficiency. In addition, the discharging piece 8 and the guide piece cooperate with the spiral pushing plate 13 to realize automatic slagging-off, and other auxiliary instruments are not needed for slagging-off, so that the device is convenient to use.

[0033] Further, the discharging piece 8 is in a triangular three-dimensional structure, and a slagging-off channel is formed in the inner side of the discharging piece 8. Preferably, the discharging piece 8 is in a right-angled triangle shape, and comprises a right-angled side a, a right-angled side b and a hypotenuse c. The right-angled side a is fixed on the first furnace door 3, so that when the first furnace door 3 is rotated with the furnace body 1 and the right-angled side a is in a plumb direction, the hypotenuse c and the staggered side of the right-angled side a are in a horizontal placement state, and at this time, the discharging piece 8 is in a maximum discharging angle.

[0034] Preferably, a plurality of second blocking rods 12 are arranged at the communication position of the discharging piece 8, that is, the feeding position of the slagging-off channel is filtered by the plurality of second blocking rods 12, so that large solid materials cannot enter the slagging-off channel and are discharged, thereby realizing the above-mentioned continuous feeding at the other end of the furnace body 1 and the continuous operation of the cracking furnace. In addition, the large solid materials can be filtered and then fall back into the furnace body 1, so that the slagging-off through slot is prevented from being blocked.

[0036] In the embodiment, the spiral pushing plate 13 pushes the slag onto the collecting piece 10, the slag falls into the buffer piece 9 by gravity when the collecting piece 10 is above, and the slag enters the discharging piece 8 through the buffer piece 9, and then is discharged through the through slot, in the embodiment, the collecting piece 10, the buffer piece 9 and the pushing piece 8 continuously change the angle when the furnace body 1 rotates, so that the slag and the large solid material not entering the pushing piece 8 reenter the pyrolysis furnace, and the problem of clogging the discharging through slot is prevented.

[0037] Preferably, one end of the buffer piece 9 towards the axis of the furnace body 1 is formed with a connecting position which is connected with the communicating position, so that the buffer piece 9 can be effectively connected with the discharging piece 8 after the first furnace door 3 is closed, and the slag falling out from the buffer piece 9 and the discharging piece 8 is prevented, and the discharging efficiency is improved.

[0038] Further, a plurality of first blocking rods 11 are installed at the slag feeding position of the collecting piece 10, the first blocking rods 11 also play a filtering role, so that the large solid material cannot enter the collecting piece 10.
