[0025] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0026] like Figure 1~Figure 3 The box-type furnace cover and its opening and closing device shown in the figure include a first assembly plate 1 and a second assembly plate 2 that are mutually buckled and used to cover the charging trough 6 from above. Specifically, a set of box-type furnace cover can be used to cover at least one row of material grid openings of the charging trough 6. In this embodiment, a set of box-type furnace cover covers a row of material grid openings. Figure 4 The charging chute 6 shown in FIG. 1 has six rows of material openings, so that Figure 3 It can be seen that six sets of box-type furnace cover plates are used.

[0027] The first assembly plate 1 includes a first lower plate and a first upper plate 11 which are arranged from bottom to top and formed as one piece. One side of the connecting end of the first lower plate and the second assembly plate 2 and one side of the connecting end of the first upper plate 11 and the second assembly plate 2 are both provided with square grooves inwardly. The connecting end of the first upper plate 11 and the second assembly plate 2 also extends with a Z-shaped protrusion protruding from the outer side of the edge of the first lower plate. The other end and both sides of the first lower plate also extend with first material stop strips 12 respectively.

[0028] The second assembly plate 2 includes a second lower plate and a second upper plate 21 which are arranged from bottom to top and are integrally formed. One side of the connecting end of the second lower plate and the first assembly plate 1 and one side of the connecting end of the second upper plate 21 and the first assembly plate 1 are both provided with square grooves inwardly. The connecting end of the second upper plate 21 and the second assembly plate 2 is also provided with a Z-shaped recessed portion recessed into the inner side of the edge of the first lower plate. When the first assembly plate 1 and the second assembly plate 2 are assembled, the Z-shaped recessed portion is located at the lower end of the Z-shaped protrusion, and second stop strips 22 are respectively extended from the other end and both sides of the second lower plate.

[0029] Specifically, the arrangement of the first material stopper strip 12 and the second material stopper strip 22, and the Z-shaped recess being at the lower end of the Z-shaped protrusion, these two stepped structures can be used to prevent auxiliary materials from leaking into the box body through the outer side of the box-type furnace cover and the gap in the middle after buckling.

[0030] like Figure 1 , Figure 3 The cover opening and closing device shown is used for opening and closing the cover of a box-type furnace, and includes a pair of cover auxiliary mechanisms 3 and a pair of rotating plate mechanisms 4.

[0031] The two cover plate auxiliary mechanisms 3 are respectively arranged on the first assembly plate 1 and the second assembly plate 2, and the cover plate auxiliary mechanism 3 includes a bottom block 31. The bottom block 31 is made of insulating material, such as rubber. The end of the bottom block 31 opposite to the box-type furnace 5 is open, and a horizontal plate 32 extends from the other end. The upper end of the bottom block 31 is provided with a first linear mechanism 33 arranged parallel to the length direction of the box-type furnace cover. Specifically, a part of the first linear mechanism 33 is also on the horizontal plate 32. The output directions of the first linear mechanisms 33 of the two cover plate auxiliary mechanisms 3 are opposite, and a first top plate 34 is provided at one end of the output shaft of the first linear mechanism 33.

The rotating plate mechanism 4 includes a rotating motor 41 whose output direction is parallel to the width direction of the box-type furnace cover plate. The rotating motor 41 is fixed to the side of a bracket on the inner wall of the box-type furnace 5. A rotating ring 42 is fixed on the outer peripheral side of the output shaft of the rotating motor 41. An insert block 43 matching the opening of the bottom block 31 is provided on the outer peripheral side of the rotating ring 42. When the insert block 43 is horizontal, the bottom block 31 can be sleeved on the insert block 43 after moving toward the insert block 43. The rotating plate mechanism 4 also includes a rotating seat 44 fixed to the inner wall of the box-type furnace 5. One end of the output shaft of the rotating motor 41 is rotatably matched with the rotating seat 44.

[0034] Working method:

[0035] First, the steps of opening the box-type furnace cover are described: preferably, after the graphitization is completed, as in the current conventional process, a part of the auxiliary materials are first removed, and the specific removal method can be suctioned by a suction crane. Then, the two first linear mechanisms 33 are started, and the first assembly plate 1 and the second assembly plate 2 are separated by the two first top plates 34, and each horizontal plug block 43 is inserted into the opening of the bottom block 31 and inserted tightly, and then each rotating motor 41 is started to rotate the cover auxiliary mechanism 3 and the first assembly plate 1 as a whole, and the cover auxiliary mechanism 3 and the second assembly plate 2 as a whole.

[0036] Next, the steps for opening the cover of the box-type furnace are described: through each rotating motor 41, the cover auxiliary mechanism 3 and the first assembly plate 1, as well as the cover auxiliary mechanism 3 and the second assembly plate 2 are returned to the horizontal state, and then the two second linear mechanisms 35 are started, and the second top plate 36 is used to press against the inner wall of the box-type furnace 5 to separate the insert block 43 and the bottom block 31 until the first assembly plate 1 and the second assembly plate 2 are pushed back to the mutually engaged position.

[0037] The above are only some of the embodiments listed in this application and are not intended to limit this application.
