Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a multi-outlet funnel for liquids. Background Art

[0002] In the daily experimental work process in the laboratory, when it is necessary to extract, separate or purify a certain component of a solution, or a dropping funnel is used to add liquid during the reaction process, work needs to be carried out through a funnel. Therefore, the funnel is an essential experimental tool in the laboratory.

[0003] In the prior art, a utility model patent with the patent number CN202020546258.2 discloses a precision separating funnel, which includes a funnel body. An opening is provided at the top of the funnel body, and a sealing plug is provided in the opening. A first liquid outlet pipe is provided at the bottom of the funnel body, and a second liquid outlet pipe is provided at the lower part of the funnel body. A stopcock sleeve is provided on the first liquid outlet pipe, a stopcock is provided in the stopcock sleeve, and a through hole is provided on the stopcock. The second liquid outlet pipe is inclined downward from top to bottom along the direction from near to far from the funnel body. A sealing member is detachably connected in the second liquid outlet pipe. One end of the sealing member is located inside the second liquid outlet pipe, and the other end is located outside the second liquid outlet pipe. The inner diameter of the second liquid outlet pipe is larger than the inner diameter of the first liquid outlet pipe.

By setting liquid outlet pipes with two different inner diameters, the corresponding liquid outlet pipes can be opened and closed respectively according to requirements, increasing the outflow speed of the upper and lower layer liquids during the separation work without affecting the liquid separation effect. However, in experimental work, sometimes the staff not only needs to experiment with one kind of liquid. When multiple liquids need to be experimented, the experimenter can only conduct experiments one by one through this funnel. Especially when comparative experiments are required, multiple funnels need to be used simultaneously. Not only do they need to pay attention to multiple experimental objects at the same time, but there may also be errors due to the use of different funnels, resulting in inaccurate experimental results.

At the same time, the filtering cover 2 can be removed, and the solution can be directly injected into the filtering body 1 by the operator for filtering. At the same time, when it is necessary to compare the filtering speeds of the same solution through filtering components 4 with different mesh numbers, the movable baffle 5 can be pushed upward and clamped through the first buckle 107 to make the through hole 501 between the movable baffle 5 and the first partition plate 102 unblocked. Then, the solution is injected into the filtering body 1, and the solution is filtered through different filtering components 4 on the two funnel rods 104 to compare the filtering speeds.

[0032] In summary, the present utility model divides the filtering body 1 into two filtering chambers by setting the first partition plate 102 and the movable baffle 5 to filter different solutions separately. At the same time, the two filtering chambers can be separated and connected by the movable baffle 5, and the filtering speeds of the same solution through different filtering components 4 can be compared. When the staff conducts experiments, they can operate through one filtering body 1 without needing to pay attention to multiple experimental objects simultaneously, and the errors in the experiments are reduced. By setting the support frame 3, it is convenient to support the filtering body 1 without the need for installation. Through the clamping between the limit groove 301 and the limit block 103, it is convenient for disassembly and installation.
