Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

As shown in FIGS. 1-2, in the embodiment of the present invention, a filter device for laboratory includes: feed liquor pipe 1, filter chamber 4 and protecting box 7, feed liquor pipe 1 and honeycomb duct 2 fixed connection, honeycomb duct 2's both ends respectively with the one end fixed connection of two filter tubes 3, fixed mounting has a plurality of first filter layers 8 on the filter tube 3, the quantity of protecting box 7 is a plurality of, and equal fixed mounting is on filter tube 3, every equal slidable mounting has a second filter layer 12 in the protecting box 7, the center pin department of second filter layer 12 is equipped with spacing hole, second filter layer 12 run through filter tube 3 and rather than lateral wall sliding fit, filter chamber 4 and the equal fixed connection of two filter tubes 3, be equipped with annular third filter layer 17 in the filter chamber 4, the junction of filter tube 3 and filter chamber 4 is equipped with check valve 16, filter chamber 4 and the coaxial fixed mounting of drain pipe 6.

In practical application, after liquid to be filtered is input from the liquid inlet pipe 1, the liquid to be filtered flows into the two filter pipes 3 from the two ends of the flow guide pipe 2 respectively, then is filtered by the plurality of second filter layers 12, along with the continuous input of the liquid to be filtered by the liquid inlet pipe 1, the liquid in the filter pipes 3 flows into the filter cavity 4, in the process, the liquid is filtered by the first filter layer 8 again, after flowing into the filter cavity 4, the liquid cannot flow to the filter pipes 3 from the filter cavity 4 due to the arrangement of the one-way valve 16, and then the liquid flows out through the liquid outlet pipe 6 finally after being filtered by the third filter layer 17 in the filter cavity 4, so that multi-stage filtration is realized; furthermore, after long-term use, the second filter layer 12 in the protective box 7 can be replaced; compared with the prior art, this design adopts two filter pipes 3 to be equipped with first filter layer 8 and a plurality of second filter layer 12, and the third filter layer 17 in the cooperation filter chamber 4 treats and filters liquid and carries out the multistage filtration, avoids filtering insufficient problem, through the regulation and control to protective housing 7, can change second filter layer 12, avoids changing the problem of the cost increase that whole device caused.

As shown in fig. 1, as a preferred embodiment of the present invention, a sealing gasket 9 is disposed at the connection position of each first filtering layer 8 and the filtering pipe 3. The sealing gasket 9 prevents liquid from leaking from the joint of the first filtering layer 8 and the filtering pipe 3, and the safety of the device is improved.

As shown in fig. 1-2, as another preferred embodiment of the present invention, an annular ring-shaped baffle 5 is fixed at the joint of the filter chamber 4 and the liquid outlet pipe 6, the inner wall of the third filter layer 17 is fixedly connected to the ring-shaped baffle 5, and the outer wall of the third filter layer 17 is fixedly connected to the filter chamber 4.

In this embodiment, treat that filter liquid gets into filter chamber 4 after, because the stopping of ring baffle 5, can not flow into drain pipe 6 at once, need wait for the liquid increase of inflow to make the liquid level be higher than ring baffle 5's height, third filter layer 17 filters liquid fully in this process, increases the filter effect of device.

As shown in fig. 1, as another preferred embodiment of the present invention, a sliding plate 10 is slidably mounted on the end of the protection box 7 far from the filter tube 3, and a handle 11 is fixed on the outer wall of the sliding plate 10.

During the use, handle 11 is held to the hand, can application of force slide 10, accomplish opening and shutting to protective housing 7, use a period of time after, can open protective housing 7, with the certain angle of second filter layer 12 rotation for second filter layer 12 in the filter tube 3 is in brand-new state, second filter layer 12 uses the back completely, takes out second filter layer 12 and can change the second filter layer 12 of renewal and install in protective housing 7, the setting of protective housing 7 avoids the unused part of second filter layer 12 after the installation to be infected with the dust, increases the practicality of device.

As shown in fig. 3, as another preferred embodiment of the present invention, the top plate and the bottom plate of the protection box 7 are respectively provided with an installation rod 14, two the opposite surfaces of the installation rod 14 are respectively hinged with a clamping block 13, each of the joints of the installation rod 14 and the protection box 7 is fixed with a magnetic block 15, and the opposite surfaces of the clamping block 13 and the magnetic block 15 are magnetically repellent.

When the second filter layer 12 is replaced, the second filter layer 12 slides in the protective box 7, the clamping block 13 rotates under stress and keeps a close state with the second filter layer 12, after the clamping block 13 rotates relative to the mounting rod 14, a gap between the clamping block 13 and the magnetic block 15 is reduced, when the limiting hole of the second filter layer 12 moves to the position of the clamping block 13, the clamping block 13 overturns to enter the limiting hole under the action of magnetic repulsion force, so that the limiting of the second filter layer 12 is realized, and at the moment, the second filter layer 12 is rotatably connected with the clamping block 13.
