a novel sealing assembly structure of a slag pump comprises a slag pump body, wherein a rotating shaft is arranged at one end of the slag pump body, a packing box is sleeved outside the rotating shaft and connected with the slag pump body, a packing cavity is formed in the inner side of the packing box, an inner baffle and an outer baffle are arranged at the inner end and the outer end of the packing cavity respectively, packing is arranged on one side, close to each other, of the inner baffle and the outer baffle, and a soft packing cavity is formed between the two pieces of packing;
the outer end of the packing cavity is provided with a gland which is sleeved on the rotating shaft, and a screw hole communicated with the soft packing cavity is drilled on the packing box.
Preferably, the packing is a packing, and the packing is coated on the outer side of the rotating shaft.
Preferably, the soft filler cavity is filled with soft fillers, and the soft fillers are in a daub shape.
Preferably, the soft filler is injected into the soft filler cavity through a high-pressure gun.
The utility model has the advantages that:
the inner side of the stuffing box is provided with the soft stuffing cavity, and the soft stuffing is in a daub shape and has special plasticity, the cylindrical sliding block can be formed by the stuffing at two ends, the inner baffle and the outer baffle in the soft stuffing cavity, a very thin liquid film is generated on a relative motion surface with the rotating shaft, and the friction heat is close to zero, so that the effect of no leakage of ash (slag) water media is achieved, and the problems that the mechanical seal is easy to lose efficacy and the stuffing has leakage are solved.

Fig. 1 is a schematic structural view of a novel sealing assembly structure of the ash pump provided by the utility model.
In the figure: 1 ash pump body, 2 axis of rotation, 3 packing box, 4 soft packing chamber, 5 packings, 6 gland, 7 screw, 8 interior baffles, 9 outer baffles.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1, a novel sealing assembly structure of a slag pump comprises a slag pump body 1, wherein a rotating shaft 2 is arranged at one end of the slag pump body 1, a packing box 3 is sleeved outside the rotating shaft 2, the packing box 3 is connected with the slag pump body 1, a packing cavity is formed in the inner side of the packing box 3, an inner baffle 8 and an outer baffle 9 are respectively arranged at the inner end and the outer end of the packing cavity, packing 5 is arranged on one side, close to each other, of the inner baffle 8 and the outer baffle 9, the packing 5 is a packing, the packing 5 is wrapped outside the rotating shaft 2, a soft packing cavity 4 is formed between the two packing 5, soft packing is filled in the soft packing cavity 4, the soft packing is in a daub shape, and the soft packing is injected into the soft packing cavity 4 through a high-pressure gun;
the outer end of the packing cavity is provided with a gland 6, the gland 6 is sleeved on the rotating shaft 2, and a screw hole 7 communicated with the soft packing cavity 4 is drilled on the packing box 3.
