Abstract
The utility model relates to a water seal for a chemical selection reaction tank in rare-earth production, and belongs to the technical field of the sealing of stirring holes of chemical selection reaction tanks in rare-earth production. The water seal comprises the chemical selection reaction tank and a stirring shaft, wherein a stirring hole is formed in the middle of the top of the chemical selection reaction tank; and the lower end of the stirring shaft is inserted into the chemical selection reaction tank through the stirring hole. The water seal is characterized in that a fixing ring is fixed on the stirring shaft outside the chemical selection reaction tank; sealing covers with annular structures are fixed on the outer side wall of the fixing ring; sealing water tanks with annular structures are formed at the lower ends of the sealing covers; the inner diameters of the sealing water tanks are greater than the diameter of the stirring hole; the lower ends of the sealing covers are arranged in the sealing water tanks; and the sealing water tanks are fixed to the top of the chemical selection reaction tank. The water seal is simple in structure, and acid mist in the chemical selection reaction tank is prevented from overflowing to the outside from the stirring hole effectively under the matching of the sealing covers and the sealing water tanks, so that the aim of protecting a speed reducer on a stirrer and ambient environment is fulfilled.
Description
Technical field
The utility model relates to and a kind ofly selects the retort water seal for Rare Earth Production, belongs to Rare Earth Production and selects retort poke hole technical field of sealing technology.
Background technology
To select the atmospheric pressure in the workshop section to select retort in Rare Earth Production, because process conditions are often changed agitator, to select retort crown center position to reserve the poke hole of a diameter 350mm in order changing conveniently in change, be convenient to the installation of paddle.But often have in process of production acid mist to overflow from poke hole, the reductor on the corrosion agitator pollutes surrounding environment simultaneously.Because this poke hole diameter is larger, if adopt the mode of mechanical seal, its expense is higher.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and select the retort water seal for Rare Earth Production, it is simple in structure, has avoided changing the acid mist that selects in the retort and be spilled over to the external world from poke hole.
Described in the utility modelly select the retort water seal for Rare Earth Production, comprising selected retort and shaft, changing selects retort crown center position to offer poke hole, the shaft lower end is selected in the retort by being inserted in of poke hole, it is characterized in that: the shaft outside retort is selected in change is fixed with retainer ring, be fixed with the seal cover of loop configuration on the retainer ring lateral wall, corresponding seal cover lower end is provided with the sealed cistern of loop configuration, the sealed cistern internal diameter is greater than the poke hole diameter, the seal cover lower end is arranged in the sealed cistern, and being fixed on of sealed cistern selected the retort top.
When retort work is selected in change, to fill up water to sealed cistern, and the seal cover lower end is flooded, this moment seal cover and change selected and just consisted of a complete annular seal space between the retort.When shaft begins to rotate, meeting drives retainer ring and seal cover rotates together, because the seal cover lower end is submerged in the sealed cistern of loop configuration, so annular seal space is in and finishes sealing state when rotating always, if changing the acid mist that selects in the retort overflows from poke hole, acid mist can only in annular seal space, can not be diffused into the external world.
In order to make the utility model play better sealing effectiveness, between described retainer ring and shaft, be provided with sealing ring, sealing ring is installed on the retainer ring.
Compared with prior art, the utlity model has following beneficial effect:
By the utility model, it is simple in structure, under the cooperation of seal cover and sealed cistern, has effectively avoided changing the acid mist that selects in the retort and be spilled over to the external world from poke hole, thereby reached reductor on the protection agitator and the purpose of surrounding environment.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Among the figure: 1, retort 7, shaft are selected in sealing ring 2, retainer ring 3, seal cover 4, sealed cistern 5, poke hole 6, change.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Such as Fig. 1, shown in Figure 2, be used for Rare Earth Production and select the retort water seal, comprising selected retort 6 and shaft 7, changing selects retort 6 crown center positions to offer poke hole 5, shaft 7 lower ends are selected in the retort 6 by poke hole 5 being inserted in, shaft 7 outside retort 6 is selected in change is fixed with retainer ring 2, be provided with sealing ring 1 between retainer ring 2 and the shaft 7, sealing ring 1 is installed on the retainer ring 2, be fixed with the seal cover 3 of loop configuration on retainer ring 2 lateral walls, corresponding seal cover 3 lower ends are provided with the sealed cistern 4 of loop configuration, sealed cistern 4 internal diameters are greater than poke hole 5 diameters, seal cover 3 lower ends are arranged in the sealed cistern 4, and sealed cistern 4 being fixed on are selected retort 6 tops.
In the present embodiment, above-mentioned seal cover 3, retainer ring 2 and sealed cistern 4 all adopt the fiberglass manufacturing, and manufacturing expense is low, dismounting is easy, are convenient to maintenance.
When retort 6 work is selected in change, to fill up water to sealed cistern 4, and seal cover 3 lower ends are flooded, this moment seal cover 3 and change selected and just consisted of a complete annular seal space between the retort 6.When shaft 7 begins to rotate, meeting drives retainer ring 2 and seal cover 3 rotates together, because seal cover 3 lower ends are submerged in the sealed cistern 4 of loop configuration, so annular seal space is in and finishes sealing state when rotating always, if changing the acid mist that selects in the retort 6 overflows from poke hole, acid mist can only in annular seal space, can not be diffused into the external world.
