Conventional ion exchange unit is to adopt cylindrical structural mostly, material enters after cylinder, material easily along inboard wall of cylinder flow or in a certain side flow, cause material skewness, affect the rate of utilization of ion exchange resin, easily cause product to adsorb in process of production inhomogeneous, resolve not exclusively, affect yield and the throughput of product.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of ion exchange unit of producing ammonium paratungstate is provided, and solves the problems of the technologies described above.
The purpose of this utility model is achieved through the following technical solutions: a kind of ion exchange unit of producing ammonium paratungstate, comprise upper cover, lower cover, be arranged at the cylinder between described upper cover and lower cover, potting resin in cylinder, on upper cover, be provided with opening for feed, water-in and venting port, lower cover is provided with discharge port, leakage fluid dram, in cylinder, be provided with several spargers, cylinder 1 side is provided with several resin overside ports.
Described sparger is evenly distributed with some apertures.
On described cylinder, be also provided with viewing window.
On described cylinder, be also provided with sensor, sensor is connected with Controlling System.
Advantage of the present utility model: owing to adopting the structure that is provided with several spargers in cylinder, make the material can bias current, material distributes more even, effectively improve the rate of utilization of ion exchange resin, cylinder is divided into some chambers by sparger simultaneously, can reduce resin internal pressure, be conducive to improve the regeneration degree of resin.
Column side face is provided with several resin overside ports, is also provided with viewing window on cylinder, makes more convenient to operate.
On cylinder, be also provided with sensor, make easy to operately, whole process is easy to automatization control.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model sparger.
In figure, cylinder 1, opening for feed 2, water-in 3, resin overside port 4, leakage fluid dram 5, discharge port 6, sparger 7, viewing window 8, sensor 9, aperture 10, upper cover 11, lower cover 12, venting port 13.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of ion exchange unit of producing ammonium paratungstate, comprise upper cover 11, lower cover 12, be arranged at the cylinder 1 between described upper cover and lower cover, the interior potting resin of cylinder 1, on upper cover, be provided with opening for feed 2, water-in 3 and venting port 13, lower cover 12 is provided with discharge port 6, leakage fluid dram 5, in cylinder 1, be provided with 4 spargers 7, described sparger 7 is evenly distributed with some apertures 10, cylinder is divided into 3 chambers by sparger 7, and cylinder 1 side is provided with 3 resin overside ports 4.
Main processes is, sodium tungstate solution enters from opening for feed 2, and sodium tungstate solution is adsorbed by resin anion(R.A), owing to adopting the structure that is provided with several spargers in cylinder, make the material can bias current, material distributes more even, effectively improves the rate of utilization of ion exchange resin.After resin anion(R.A) absorption sodium tungstate solution reaches capacity, wash with clear water, after resin washing finishes, add the ammonium chloride-ammonium hydroxide mixing solutions preparing, through parsing, obtain ammonium tungstate solution, send evaporative crystallization to obtain ammonium paratungstate product, resolving had been both product liquid switching process, was also resin regeneration process simultaneously.Sparger 7 is 3 chambers by cylinder 1 interior separation, compares an inner chamber, can reduce resin internal pressure, is conducive to improve the regeneration degree of resin.
In order to be easy to operate, whole process is easy to automatization control, on described cylinder 1, is also provided with viewing window 8, on described cylinder 1, is also provided with sensor 9, and sensor 9 can comprise under meter, specific gravity hydrometer etc., and sensor 9 is connected with Controlling System.
Structure in this example is only for for the illustrating and explaining of claim, so that popular reading comprehension should not be considered as the restriction for claim, scope and legal equivalent feature that protection domain of the present utility model should be recorded with claim be as the criterion.
