Uniformly, the requirement of each side such as resistance to water-flow, exchange velocity, backwash effect could be balanced.Therefore, granularity and particle size range be from
One of important physical index of sub-exchange resin.
The measurement of resin size and particle size range must use and arrive a kind of braid fabric testing sieve.Laboratory uses at present
Testing sieve be made up of screen frame and underlying metal bolting silk net, screening resin particle is such as sieved, by sieve using hygrometric state when spending
It is put into the screening funnel equipped with water, if any improper during operation, resin is easy to drift out from sieve upper limb, is such as sieved using dry state
Point, resin particle is also easily jumped out from sieve upper limb.In addition, in screening process, screen cloth mesh can be blocked by resin particle, need
Carry out clear net.During clear net, by sieve turn over (bottom screen is upward) be placed in an enamel tray, hygrometric state is sieved then with thin water
Stream rinses screen cloth repeatedly, and the resin particle blocked in screen cloth is washed down substantially, sweeps away the resin come and sieve is transferred back to from enamel tray
Net continues to sieve.Dry state screening is then cleaned up the particle in mesh with brush, then the sample in enamel tray is transferred back into sieve
Son continues to sieve.Once complete screening process needs repeatedly to operate above-mentioned steps, to the test procedure bring it is cumbersome with not
Just.
Utility model content
The utility model is precisely in order to avoid the weak point present in above-mentioned prior art, there is provided one kind is used to sieve
The experiment screen device of ion exchange resin.
The present invention adopts the following technical scheme that to solve technical problem：A kind of testing sieve for being used to sieve ion exchange resin
Device, screen frame are bottomless tubular structure, and its bottom is set around the inner tube wall neck of one week along inner tube wall, and top sets the horizontal sieve to turn up
Frame upper limb, bottom screen are fixedly connected in the neck, and upper screen is bonded setting with the screen frame upper limb, and by described
Closed and locked by shell fragment buckle on the outside of layer screen cloth and the screen frame upper limb.
Further, the screen frame is bottomless cylindrical shape, and the neck is accordingly set to loop configuration.
Further, rubber gasket is set between the screen frame upper limb and the upper screen, and passes through rubber seal
Washer sealing connects.
Further, the quantity of the shell fragment button is no less than two, and each shell fragment button is uniformly arranged along the screen frame upper limb.
The utility model provides a kind of experiment screen device for being used to sieve ion exchange resin, has below beneficial to effect
Fruit：
1st, upper screen is set at the top of screen frame, can prevents that resin particle is drifted out from screen frame upper limb when hygrometric state from sieving or dry state is sieved
When resin particle jumped out from screen frame upper limb；
Reusability enamel tray, resin shift back and forth when the 2nd, avoiding netting clearly, at the same it also avoid transfer when resin sample go out
Now loss causes testing result inaccurate；
3rd, it is simple in construction, easy for installation, the test procedure of resin screening can be greatly simplified, shortens the sample analysis cycle.

Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that described implementation
Example is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, this area
The every other embodiment that those of ordinary skill is obtained under the premise of creative work is not made, belongs to the utility model
The scope of protection.
As shown in FIG. 1 to 3, its structural relation is：Screen frame 1 is bottomless tubular structure, and its bottom is set around interior along inner tube wall
The barrel neck of one week, top set the horizontal screen frame upper limb 4 to turn up, and bottom screen 2 is fixedly connected in neck, upper screen 3
Setting is bonded with screen frame upper limb 4, and locking is engaged by shell fragment button 6 by upper screen 3 and the outside of screen frame upper limb 4.
Preferably, screen frame 1 is bottomless cylindrical shape, and neck is accordingly set to loop configuration.
Preferably, rubber gasket 5 is set between screen frame upper limb 4 and upper screen 3, and it is close by rubber gasket 5
Envelope connection.
Preferably, the quantity of shell fragment button 6 is no less than two, and each shell fragment button 6 is uniformly arranged along screen frame upper limb 4.
When specifically used, sieve according to hygrometric state, first open testing sieve is put into the screening funnel equipped with water, will with water
Resin particle sample in 100mL graduated cylinders is transferred in testing sieve.Rubber gasket 5 is fitted on screen frame upper limb 4, then will
Upper screen 3 is coaxially fitted on rubber gasket 5, finally with each shell fragment button 6 by screen frame upper limb 4, the and of rubber gasket 5
The engaging of upper screen 3 is locked.
The continuous testing sieve that moves up and down, makes resin in underwater exercise, and sieve should not leave the water surface, and continuous operation is about
5min.If the mesh of bottom screen 2 is blocked by resin particle substantially, testing sieve is overturn, bottom is rinsed repeatedly with thin current and sieves
Net 2, rinsing the resin particle to get off can be intercepted and captured by upper screen 3, and resin particle to be occluded washes down substantially, keep bottom screen
2 upwards, continue to move to sieve, make resin in underwater exercise.Lower resin particle is blocked or sieves when screen cloth mesh there is no
Less than 50, then it can determine whether that screening is clean, otherwise continue above-mentioned steps, until screening is clean.
Sieved according to dry state, sieve be positioned in an enamel tray, 100mL resin particle samples are transferred in sieve,
Rubber gasket 5 is fitted on screen frame upper limb 4, then upper screen 3 is coaxially fitted on rubber gasket 5, finally
