Abstract
The utility model relates to a sealing device for a rare earth extraction tank, which belongs to the field of sealing components of rare earth extraction tanks. The sealing device for a rare earth extraction tank comprises an extraction tank, an upper opening is arranged on the extraction tank, and a sealing cover plate is covered on the upper opening. The technical scheme includes that an annular water tank is arranged at the periphery of the upper opening, a partition board which is bent downwards and matches with the water tank is arranged at the periphery of the sealing cover plate, and the partition board and the sealing cover plate form a semi-sealed structure. After the prior art is improved, the water tank with secondary sealing effect is additionally arranged on the upper opening of the extraction tank, the sealing cover plate is improved, the sealing effect of the sealing cover plate is strengthened, and accordingly the sealing device has the advantages that the sealing device is simple in structure and low in manufacturing cost, can improve a work environment of an extraction post, guarantees health of personnel, and avoids air pollution due to volatile gas.
Description
Technical field
The utility model belongs to rare earth extraction groove sealing element field, is specifically related to a kind of rare earth extraction groove tightness system.
Background technology
The isolating extraction tank of rare earth extraction, usually adopt PVC plastic plate welding cell body, the loam cake sealing of cell body adopts the PVC plate to seal, in actual moving process, owing to influenced by the restriction of sheet material self and the working temperature of cell body, the PVC cover plate occurs distortion easily and causes poorly sealed, because extraction agent and kerosene are filled in the extraction tank the inside, be subjected to the reaction temperature condition effect, cause a large amount of volatilization of organic extractant and kerosene, volatilize pungent gas, polluted air not only, but also having a strong impact on employee's Working environment and healthy.For this reason, be badly in need of existing extraction tank structure is improved,, ensure the healthy of employee, avoid the pollution of volatilization gas air to improve the Working environment in extraction post.
The utility model content
The purpose of this utility model is prior art is improved, and provides a kind of simple in structure, cheap, can improve the Working environment in extraction post, ensures the healthy of employee, avoids the rare earth extraction groove tightness system of volatilization gas to the pollution of air.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is a kind of rare earth extraction groove tightness system, comprise extraction tank, offer suitable for reading on the extraction tank, upper flap dress seal cover board, the present technique main points are that periphery suitable for reading is provided with annular water tank, the setting of seal cover board periphery be bent downwardly and with the dividing plate of tank coupling, this dividing plate and seal cover board constitute semitight shape structure jointly.
After the utility model carries out above-mentioned improvement to prior art, because the sealed cistern that installed additional suitable for reading at extraction tank, and seal cover board is improved, strengthened the sealing effectiveness of seal cover board, therefore have simple in structure, cheap, can improve the Working environment in extraction post, ensure the healthy of employee, avoid the advantage of volatilization gas the pollution of air.
Description of drawings
Fig. 1: the utility model example structure synoptic diagram.
Fig. 2: the utility model embodiment plan structure synoptic diagram.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this rare earth extraction groove tightness system, comprise extraction tank 1, offer suitable for reading 4 on the extraction tank 1,4 lid dress seal cover boards 4 suitable for reading, the present technique main points are that 4 peripheries suitable for reading are provided with annular water tank 2, seal cover board 4 periphery be provided be bent downwardly and with the dividing plate 3 of tank coupling, this dividing plate 3 and seal cover board 4 be common to constitute semitight shape structures.
Like this, at suitable for reading 4 of extraction tank 1 a circle tank 2 is installed, be full of water in tank 2 the insides, seal cover board 4 is covered, the dividing plate 3 of seal cover board 4 just is inserted in the tank 2 behind fastening, play a water-lute effect completely, improved sealing effectiveness, the gas of the organic extractant in the extraction tank 1 just evaporate in the air no longer easily.
After the utility model carries out above-mentioned improvement to prior art, because the tank 2 that plays the secondary seal effect that installed additional suitable for reading at extraction tank 1, and seal cover board 4 is improved, strengthened the sealing effectiveness of seal cover board 4, therefore have simple in structure, cheap, can improve the Working environment in extraction post, ensure the healthy of employee, avoid the advantage of volatilization gas the pollution of air.
