Description

Technical Field

[0001] The present invention relates to the technical field of waste oil collection and treatment, and in particular to an integrated laboratory waste oil collection device and a use method thereof. Background Art

[0002] With the continuous improvement of social productivity and scientific and technological levels and the change of social concepts, occupational health issues are increasingly valued by companies and individuals. Among them, the experimental waste oil in the laboratory is highly volatile and may pollute the environment. Therefore, it is necessary to collect and treat the waste oil in the laboratory in a unified manner.

[0003] In the prior art, when collecting waste oil, the general operation method is to open the collection barrel cover, insert the funnel into the collection barrel, and then the staff pours the waste oil into the collection barrel;

[0004] However, the above operation method still has certain shortcomings. During the collection process, since the barrel cover is generally a threaded cover, it may be inconvenient for the staff to open it with one hand. At the same time, when the waste oil is poured out, the funnel needs to be taken out and the barrel cover is screwed on the barrel mouth. However, some waste oil may remain on the taken out funnel, and oil dripping may occur. At the same time, the waste oil remaining on the funnel may evaporate and pollute the environment. Summary of the invention

[0005] The purpose of the present invention is to solve the problems raised in the above background technology and to propose an integrated collection device for laboratory waste oil.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] A draft tube, threadedly connected to the bottom of the funnel;

[0012] A connecting plate, connected to the connecting ring by threads;

[0013] A vent pipe, fixedly connected to the connecting ring;

[0014] The mesh screen is provided with two layers, namely mesh screen one and mesh screen two. The mesh holes of mesh screen one and mesh screen two are arranged alternately. The mesh hole diameter of mesh screen one is 1.5 times the mesh hole diameter of mesh screen two. The distance between mesh screen one and mesh screen two is 80-90% of the mesh hole diameter of mesh screen one.

[0015] Preferably, a first sealing gasket is fixedly connected to the funnel, and the flip cover is in contact with the first sealing gasket.

[0016] Preferably, a threaded sleeve is fixedly connected to the bottom of the funnel, a threaded groove is provided on the top of the guide tube, and the guide tube is threadably connected to the threaded sleeve.

[0017] Furthermore, a second sealing gasket is fixedly connected to the top of the guide tube, and the second sealing gasket abuts against the bottom end of the funnel.

[0018] Preferably, a first magnet is fixedly connected to the side wall of the mesh screen, and a second magnet is fixedly connected in the funnel, and the first magnet and the second magnet attract each other.

[0019] Preferably, a limiting block is fixedly connected to the flip cover, a limiting ball is connected to the limiting block, a slot is provided on the funnel, and the limiting ball matches the slot.

[0035] Reference Figure 1-Figure 7 , an integrated collection device for waste oil in a laboratory, comprising:

[0036] Funnel 1;

[0037] The flip cover 2 is rotatably connected to the funnel 1 via a hinge 201;

[0038] A mesh screen 8, detachably connected to the funnel 1;

[0039] The flow guide tube 5 is threadedly connected to the bottom of the funnel 1;

[0040] The connecting plate 7 is threadedly connected to the connecting ring 3;

[0041] A vent pipe 6 is fixedly connected to the connecting ring 3;

[0042] The mesh screen 8 is provided with two layers, namely mesh screen 1 and mesh screen 2, the mesh holes of mesh screen 1 and mesh screen 2 are staggered, the mesh hole diameter of mesh screen 1 is 1.5 times the mesh hole diameter of mesh screen 2, and the distance between mesh screen 1 and mesh screen 2 is 80-90% of the mesh hole diameter of mesh screen 1; when the waste oil passes through mesh screen 1 and mesh screen 2 in sequence, the staggered two layers of mesh screens can filter the impurities therein more thoroughly, and the diameter ratio design of mesh screen 1 and mesh screen 2 can make the bubbles generated when the waste oil passes through mesh screen 1 be destroyed by mesh screen 2, so as to avoid affecting the oil filtering efficiency and effect.

[0043] Reference Figure 2-Figure 4 The connecting ring 3 is clamped on the mouth of the waste oil collection barrel. When in use, the funnel 1 can be rotatably installed on the connecting ring 3, thereby ensuring the stability of the funnel 1 after installation.

[0044] The funnel 1 is fixedly connected with a first sealing gasket 103 , and the flip cover 2 and the first sealing gasket 103 are in contact with each other.

[0045] Reference Figure 5 By setting the first sealing gasket 103 on the funnel 1, the sealing performance between the flip cover 2 and the funnel 1 can be ensured.

[0046] A threaded sleeve 4 is fixedly connected to the bottom of the funnel 1 , a threaded groove 501 is provided on the top of the flow guide tube 5 , and the flow guide tube 5 is threadably connected to the threaded sleeve 4 .

[0047] A second sealing gasket 9 is fixedly connected to the top of the flow guide tube 5 , and the second sealing gasket 9 abuts against the bottom end of the funnel 1 .

[0048] Reference Figure 4 , Figure 5 By providing the second sealing gasket 9 , the connection stability between the flow guide tube 5 and the funnel 1 can be ensured, thereby ensuring the flow guiding effect of the flow guide tube 5 .

[0049] A first magnet 801 is fixedly connected to the side wall of the mesh screen 8, and a second magnet 102 is fixedly connected to the funnel 1. The first magnet 801 and the second magnet 102 attract each other.

[0050] Reference Figure 5 , Figure 6 The first magnet 801 and the second magnet 102 are attracted to each other, thereby ensuring the stability of the mesh screen 8 after installation, thereby ensuring that the mesh screen 8 will not be moved by impact during the filtering process.

[0051] After use, the staff can also manually pull the mesh screen 8 to separate the first magnet 801 and the second magnet 102 , and then quickly pour out the material in the mesh screen 8 .

[0052] The flap 2 is fixedly connected to a limiting block 203 , the limiting block 203 is connected to a limiting ball 2031 , the funnel 1 is provided with a clamping slot 101 , and the limiting ball 2031 matches the clamping slot 101 .

[0053] A spring 2032 is fixedly connected to the limiting block 203 , and the spring 2032 and the limiting ball 2031 are fixedly connected.

[0054] Reference Figure 4-Figure 7 When the flip cover 2 is closed, the inner wall of the funnel 1 will squeeze the limiting ball 2031, and the spring 2032 will be squeezed and contracted. When the flip cover 2 is completely closed, the limiting ball 2031 slides into the slot 101. At this time, under the action of the restoring elastic force of the spring 2032, the limiting ball 2031 fully clamps the inner wall of the funnel 1, thereby ensuring the stability of the flip cover 2 after it is closed.

[0055] A handle 202 is fixedly connected to the flip cover 2 .

[0056] Reference Figure 3 , Figure 4 The handle 202 provided on the flip cover 2 makes it convenient for the staff to quickly open the flip cover 2.

[0057] Reference Figure 1-Figure 7 , a method for using an integrated laboratory waste oil collection device. During use, the staff manually pulls the handle 202 to open the flip cover 2, and pours the waste oil into the funnel 1. The mesh screen 8 set in the funnel 1 can effectively filter out impurities in the waste oil, and the filtered waste oil will flow into the waste oil collection barrel through the guide pipe 5.

[0058] The device fixes the funnel 1 on the waste oil collection barrel, and there is no need to remove the funnel 1 and then seal it. On the one hand, it solves the problem that the funnel 1 is prone to dripping oil when it is taken out, and on the other hand, it solves the problem that it is not easy for workers to open the barrel cover with one hand when pouring round-bottomed glass instruments such as distillation flasks and test tubes in the prior art, thereby improving the waste oil collection efficiency. At the same time, by setting a flip cover 2 on the funnel 1, the problem that the waste oil remaining on the funnel 1 is prone to volatilization and environmental pollution in the prior art is solved.
