Description

Air inflation sealing device
Technical field
The utility model belongs to water-tight equipment technical field, especially relates to a kind of air inflation sealing device.
Background technique
High-pressure roller mill utilizes two rollers relatively operated to be crushed by ore, in order to increase the extruding opportunity between ore, require choke feed, ore storage bin requirement for height is higher than 3m, ore storage bin above must be removed during examination and repair for high-pressure roller, so ore storage bin is fixed on the crossbeam of similar travelling crane.When removing ore storage bin, have a large amount of dusts and raise out during examination and repair for high-pressure roller, this just needs the seal arrangement that must have a good sealing effect between high pressure roller mine inlet and ore storage bin, prevents raising out of dust.
Summary of the invention
It is simple, easy to operate that the purpose of this utility model is to provide a kind of structure, the air inflation sealing device of good sealing effect.
The purpose of this utility model is realized by following technical proposals:
Air inflation sealing device of the present utility model, it is characterized in that comprising the suitable for reading large lower young square cone be located between high pressure roller mine inlet and ore storage bin active section and the air bag being located at this side's cone inside, described square cone comprises the active section entrance, Seal cage cavity, the charging air inlet being arranged on described Seal cage cavity side, lower bracket and the bottom adpting flange that set gradually from top to bottom, described air bag is arranged in described Seal cage cavity, and described charging air inlet is connected with described air bag.
Described air bag material is elastic caoutchouc.
Advantage of the present utility model:
Air inflation sealing device of the present utility model is positioned at the top of high pressure roller mine inlet, and the active section of ore storage bin end opening can reach in air inflation sealing device, prevents raising out of dust.Sealing device good sealing effect, can unload the active section on ore storage bin mouth down during examination and repair for high-pressure roller and fall in seal arrangement, remove ore storage bin, can not produce any race ash phenomenon from ore storage bin mouth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, air inflation sealing device of the present utility model, it is characterized in that comprising the suitable for reading large lower young square cone be located between high pressure roller mine inlet 8 and ore storage bin active section 7 and the air bag 1 being located at this side's cone inside, described square cone comprises the active section entrance 2, Seal cage cavity 6, the charging air inlet 3 being arranged on described Seal cage cavity 6 side, lower bracket 4 and the bottom adpting flange 5 that set gradually from top to bottom, described air bag 1 is arranged in described Seal cage cavity 6, and described charging air inlet 3 is connected with described air bag 1.
Described air bag 1 material is elastic caoutchouc.
Bottom of the present utility model adpting flange 5 and high pressure roller mine inlet 8 concrete mutually, ore storage bin active section 7 is inner through active section entrance 2 side of entering cone, by charging air inlet 3 to air bag 1 li inflation, air bag 1 is full of the space of whole Seal cage cavity 6, make the gap seals between ore storage bin active section 7 end opening and air inflation sealing device, just can normally produce.When maintenance, the gas of air bag 1 li is released a part, first unload ore storage bin active section 7, away from top ore storage bin mouth, remove ore storage bin, then unload air inflation sealing device and keep in repair.The utility model good sealing effect, can unload the ore storage bin active section 7 on ore storage bin mouth down during examination and repair for high-pressure roller and fall in seal arrangement, remove ore storage bin, can not produce any race ash phenomenon from ore storage bin mouth.
