[0027] Each positioning plate 2 is a concave-shaped structure, and a limiting column 10 is fixedly connected in the middle of the interior. A through hole is opened in the middle of the limiting column 10, and a connecting rope 11 passes through the through hole. A winding roller 12 is rotatably connected to one end of the positioning plate 2. A motor is detachably connected to the side wall of one end of the positioning plate 2 close to the top plate 1, and the output end of the motor extends into the positioning plate 2 and is detachably connected to one end of the winding roller 12.

[0028] The three positioning plates 2 correspond to the three slag collecting plates 6 , and one end of the connecting rope 11 is wound around and connected to the winding roller 12 .

[0029] The motor is started to drive the winding roller 12 to rotate. As the connecting rope 11 rises, the slag collecting plate 6 corresponding to the connecting rope 11 can be driven to rise, so that the slag collecting plate 6 can be taken out of the furnace to realize the slag cleaning function.

[0030] The three slag collecting plates 6 are all equipped with corresponding winding rollers 12, so as to realize independent drive control of the three slag collecting plates 6, thereby ensuring the sequence of slag cleaning, and performing different operations according to time, thereby ensuring the stability of slag collection.

[0031] The three stacked slag collecting plates 6 can cooperate with each other, and the slag dripping from the upper layer can be caught by the lower layer, and the filter holes of the three layers of filter screens 8 are of different sizes. The filter holes of the filter screens 8 are smaller as they go down, thereby ensuring the collection of the slag and avoiding the problem of slag falling.

[0032] In order to ensure the stable operation of the connecting rope 11, a limit column 10 is set. The connecting rope 11 is raised and lowered on the limit column 10, which can ensure that the connecting rope 11 maintains a stable vertical lifting function, thereby avoiding the shaking of the slag collecting plate 6 and reducing the risk of operation.

[0033] Embodiment 2

[0034] Further improvements are made on the basis of the first embodiment:

[0035] according to Figure 3 As shown, a groove is provided in the middle of the bottom side wall of the top plate 1, and a screw 13 is rotatably connected in the groove, three sliders 14 are threadedly connected to the screw 13, and a spacer plate 15 is fixedly connected between every two sliders 14 and at the top edge, and three positioning plates 2 are fixedly connected to the top side wall of the slider 14 by one end, and a driving motor is connected to the outer side wall at one end of the top plate 1.

[0037] By driving the motor and the screw 13, the slag collecting plate 6 can be moved to a designated position for slag cleaning operation.

[0038] Embodiment 3

[0039] Further improvements are made on the basis of the first embodiment:

A vertical back plate 4 is set at one end of the slag collecting plate 6, and a rotating shaft 9 is rotatably connected to the bottom end of the vertical back plate 4 and close to the edge of the slag collecting plate 6. The vertical back plate 4 is rotatably connected to the slag collecting plate 6 through the rotating shaft 9. One side wall of the reinforcing plate 7 is in contact with the side wall of the vertical back plate 4. One end of the filter screen 8 is tilted upward, and the connecting plate 5 is fixedly connected to the top side wall of the vertical back plate 4 through the bottom end, and the connecting plate 5 is a triangular structure. The top of the connecting plate 5 is fixedly connected to the docking plate 3, and the bottom end of the connecting rope 11 is fixedly connected to the docking plate 3. They are all fixedly connected with a fixing plate 16, a connecting groove is provided in the middle of the fixing plate 16, two holes are provided through the top side wall of the fixing plate 16, a positioning pin 17 is fixedly connected to the outer wall of the reinforcing plate 7 and close to the vertical back plate 4, the positioning pin 17 is inserted into the fixing plate 16, and the positioning pin 17 is provided with a hole corresponding to the hole, an adjusting groove 18 is provided on the side wall of the vertical back plate 4, a displacement block is slidably connected in the adjusting groove 18, and one end of the displacement block is fixedly connected to a follower plate 19, one end of the follower plate 19 is fixedly connected to an L-shaped plate 20, and a plug column 21 is fixedly connected to the top side wall of the follower plate 19, and the plug column 21 corresponds to the hole.

[0041] After the slag collecting plate 6 is moved to a suitable position, a rod is used manually to push the L-shaped plate 20 and then push it upward with force. The L-shaped plate 20 can drive the follower plate 19 to rise along the adjustment groove 18, thereby pushing the plug post 21 out of the hole groove. The limitation of the plug post 21 is lost, and under the influence of the deadweight of the slag collecting plate 6, the slag collecting plate 6 rotates along the rotating shaft 9 to an upright state, thereby cleaning out the slag on the filter screen 8.

[0042] In order to ensure reliable slag discharge, one end of the filter screen 8 is set to be an inclined structure, so that the slag can slide out along the filter screen 8 stably, and avoid safety problems caused by close manual operation.
