Description

Technical Field

[0001] The utility model relates to the technical field of sodium tungstate purification, in particular to a device for purifying sodium tungstate. Background Art

[0002] Sodium tungstate is an inorganic substance with the chemical formula Na2WO4. It is a colorless crystal or white crystalline powder. It weathers in dry air and loses crystal water at 100°C. It is soluble in water but insoluble in ethanol. Its relative density is 3.23-3.25 and its melting point is 698°C. It is used as a mordant, analytical reagent, catalyst, water treatment agent, and in the manufacture of fireproof and waterproof materials, as well as phosphotungstate and borotungstate. This product is used as a fabric auxiliary. A mixture of sodium tungstate, ammonium sulfate, ammonium phosphate, etc. is used for fireproofing and waterproofing of fibers.

A disc 47 is fixedly provided between the control cylinder 43 and the cylinder 45, and a push rod 48 is fixedly connected to the inner center of the disc 47, and a push plate 49 is fixedly connected to the front end of the push rod 48. A return spring 410 is fixedly connected between the control block 46 and the push rod 48.

[0020] In this embodiment, the heating kettle 2 is connected to the control cylinder 43, the push-pull opening 42 is made of transparent glass, the cylinder 45 and the control block 46 are threadedly connected, the disc 47 is made of highly elastic rubber material, and the push piece 49 is limited and movable at the inner position of the control cylinder 43.

[0021] Specifically, firstly, the sodium tungstate material is put into the inner side of the heating kettle 2 through the feed port 5, and the material is purified by heating the heating kettle 2. When heated, the air pressure inside the heating kettle 2 is greater than the air pressure inside the purification cylinder 41, and the airflow will push the push piece 49 to move backward, and the push rod 48 compresses the reset spring 410. Then, the toxic airflow generated by the heating of the material inside the heating kettle 2 will enter the inner side of the purification cylinder 41 through several groups of exhaust holes 44. By observing the barometer 3, the push-pull port 42 is opened and the rotating control block 46 is used to adjust the elasticity of the reset spring 410, and then the number of exhaust holes 44 is adjusted according to the pressure inside the heating kettle 2 to adjust the flow rate of the toxic gas discharge, prevent the subsequent purification from being incomplete due to the excessively fast flow rate of the toxic gas, and effectively prevent the reflux of the toxic gas at the end of the reaction inside the heating kettle 2.

[0022] In this embodiment, two groups of frame frames 411 are movably provided on the inner side of the purification cylinder 41 near the rear side, and card slots 412 are provided on the inner side of the purification cylinder 41 corresponding to the positions of the two groups of frame frames 411.

The operation is convenient, simple and convenient, and the toxic gas can be effectively prevented from being directly discharged into the air, thereby reducing the adverse effects on the health of the operator and the surrounding environment.

[0024] Working principle:

[0025] When in use, firstly, the sodium tungstate material is put into the inner side of the heating kettle 2 through the feed port 5, and the material is purified by heating the heating kettle 2. When heated, the air pressure inside the heating kettle 2 is greater than the air pressure inside the purification cylinder 41, and the airflow will push the push piece 49 to move backward, and the push rod 48 compresses the reset spring 410. Then, the toxic airflow generated by the heating of the material inside the heating kettle 2 will enter the inner side of the purification cylinder 41 through several groups of exhaust holes 44. By observing the barometer 3, the push-pull port 42 is opened and the rotating control block 46 is used to adjust the elasticity of the reset spring 410, and then the number of exhaust holes 44 is used according to the pressure inside the heating kettle 2. Adjustment can be achieved to adjust the flow rate of toxic gas discharge, prevent incomplete subsequent purification due to excessively fast flow rate of toxic gas, and effectively prevent the backflow of toxic gas at the end of the reaction inside the heating kettle 2. In addition, the toxic gas will be purified and filtered when passing through the two groups of purification plates 413 installed on the inner sides of the two groups of frames 411. When the purification plate 413 reaches a saturated state, the corresponding two groups of locks 415 are opened and the handle 414 is pulled out to replace it. It is easy to operate, simple and convenient, and effectively prevents toxic gas from being directly discharged into the air, reducing the adverse effects on the health of operators and the surrounding environment.
