Description

Sealing device of sagger for mixed powder sintering and vibrating and leveling integrated equipment Technical Field The invention relates to the technical field of mixed powder production equipment, in particular to a sealing device of a sagger for mixed powder sintering and vibration leveling and conveying integrated equipment. Background The mixed powder refers to a mixture of cobalt manganese nickel hydroxide and lithium salt. Before the sintering process of the mixed powder, the prepared mixed powder is required to be filled in a sagger, and then the mixed powder in the sagger is vibrated to ensure the uniformity of the mixed powder so as to ensure the consistency of the quality of the anode material obtained by subsequent sintering. The sagger is provided with an opening for containing the mixed powder. The sagger is divided into a flat sagger and a notch sagger. The flat-mouth sagger comprises a first containing part, the first containing part is used for containing mixed powder, and a notch is not formed in the side wall of the first containing part. The notch sagger comprises a second containing part and a stacking part which are connected, the stacking part is arranged above the second containing part, a side wall is formed on the side wall when the stacking part is connected with the second containing part, for example, an inverted trapezoid notch or an arc notch is formed on the side wall, the side wall notch is communicated with the opening of the notch sagger, when two notch saggers are stacked in the vertical direction, one notch sagger is stacked on the opening of the other notch sagger, therefore, the stacked notch sagger can enable mixed powder to exchange with external air during sintering through the side wall notch, namely oxygen required to be consumed during sintering is provided, and two waste gases, namely water vapor and carbon dioxide, are discharged, so that the sintering quality is ensured by simultaneously sintering at least two notch saggers in a stacking mode, and the production efficiency of a sintering process is further improved. The first containing part of the flat-mouth sagger and the second containing part of the notch sagger have the same shape and the same size. Before shaking, each sagger is sealed respectively, then a plurality of notched saggers are stacked below, and the flat saggers are stacked above the notched saggers. Therefore, the sealing device is used for sealing the flat-mouth sagger and also used for sealing the notch sagger. The traditional sagger sealing mode adopts sponge compaction, and the exposed notch of the flat-mouth sagger is flat, so that the sealing effect of the sponge on the flat-mouth sagger is good, but the sponge has the following problems when sealing the notch sagger: The sponge has poor suitability to a notch with a complex shape, such as a trapezoid notch or an arc notch, so that a large gap can be generated between the sponge and the inner peripheral wall of the side wall notch when the side wall notch is sealed, the sealing effect of the notch sagger is poor, more powder leakage is caused, large powder waste is caused, and the workshop production environment can be seriously polluted. Likewise, there is a lack of a better sealing means for sealing the sagger during the transport of the sagger from the shake-down section to the sintering section. For example, chinese patent of patent publication No. CN208963883U proposes a sealing structure of a lithium battery sintering powder conveying belt, which comprises a bracket, a sagger mounted on the bracket, a sealing cover is further provided on the outer side of the sagger, the sealing cover is mounted on the bracket, the sealing cover comprises a rear plate and two side plates fixed on the bracket, and a plurality of turnover plates arranged along the conveying direction of the sagger, the rear plate, the two side plates and the turnover plates seal the sagger, and the turnover plates are hinged on the bracket and are driven by a gas spring hinged on the bracket. The flip plate of the sealing cover is arranged in an upward-turned mode, the space above the sagger is utilized, the channel is prevented from being blocked when the flip plate is opened, the arrangement is reasonable, the sealing structure of the lithium battery sintering powder conveying belt can seal powder in the sagger in the sealing structure, so that the powder in the sagger is not leaked out of the sealing structure in the transportation process, but because a larger gap exists between the sealing cover and the sagger, namely, part of the powder in the sagger possibly falls between the sealing cover and the sagger in the transportation process, the peripheral wall of the sagger is contaminated with the powder, namely, the powder in the sagger is easily leaked out of the sagger in the transportation process, and the powder contaminated by the peripheral wall of the sagger is easily leaked out of the sealing structure w
