Description

Technical Field

[0001] The utility model belongs to the technical field of liquid separation, and in particular relates to a ketone preparation and liquid separation device. Background Art

[0002] Ketones are compounds with a carbonyl group connected to two hydrocarbon groups. When ketones are prepared using some methods, liquid separation is required during the experiment. Existing chemical liquid separation operations often use a separatory funnel, but when using a separatory funnel for liquid separation, the piston valve of the separatory funnel is difficult to accurately control the flow of the liquid, and it is easy to release too much liquid, causing the upper and lower layers of liquid to be discharged from the separatory funnel together, resulting in liquid separation failure. The liquid separation operation needs to be repeated again, affecting the progress of the experiment.

[0003] Therefore, a novel ketone preparation and liquid separation device is needed. Utility Model Content

[0004] In order to solve the above problems, the utility model discloses a ketone preparation and liquid separation device.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A ketone preparation and liquid separation device comprises a double cone funnel for ketone preparation and liquid separation, the double cone funnel is provided with an upper cavity and a lower cavity interconnected by double holes, a double hole valve adapted to the double holes is installed between the upper cavity and the lower cavity, a single hole valve for controlling liquid discharge is installed at the bottom of the lower cavity, two vertical tubes extend outward from the top of the lower cavity, and the two vertical tubes are respectively connected to an air guide hose, the two air guide hoses are commonly connected to a double cavity cylinder, a piston is slidably installed in the double cavity cylinder, and the two air guide hoses are respectively connected to a first cavity and a second cavity of the double cavity cylinder, one of the double holes between the upper cavity and the lower cavity is connected to a connecting pipe, and the connecting pipe is connected to a second cavity, and the extension pipe of the second cavity is installed with a rotary valve.

[0007] As a preferred technical solution of the utility model, the piston is fixedly connected with a pull rod, and the pull rod is slidably connected to the double-chamber cylinder.

[0008] As a preferred technical solution of the utility model, the double-hole valve includes: a double-hole valve body rotatably installed between the upper cavity and the lower cavity, and a first positioning plate fixedly installed on the outer wall of the double-cone funnel, the rotating shaft fixing sleeve of the double-hole valve body is provided with a first fixing seat, the first fixing seat is elastically and slidably installed with a first clamping block, and the first positioning plate is provided with a positioning groove adapted to the round head of the first clamping block.

[0009] As a preferred technical solution of the utility model, the first clamping block is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to the first fixing seat.

[0010] As a preferred technical solution of the utility model, a single hole adapted for a single-hole valve is provided at the bottom of the lower cavity.

[0014] The beneficial effects of the utility model are:

[0015] 1. When liquid separation is completed, the double-hole valve is opened, and the piston is pushed by the pull rod to compress the second cavity (the rotary valve is closed at this time), so that the air in the second cavity enters the upper cavity through the air guide hose, the connecting pipe and one of the through holes between the upper cavity and the lower cavity, and the liquid at the bottom of the upper cavity enters the lower cavity through the other through hole between the upper cavity and the lower cavity, and the excess air in the lower cavity enters the first cavity through the air guide hose. The piston control can accurately control the liquid discharge, reduce the probability of liquid separation failure, and improve the experimental efficiency;

[0016] Second, when the lower cavity is discharging liquid, the double-hole valve is rotated to close, and the single-hole valve is rotated to open. The piston is pushed by the pull rod to compress the first cavity (the rotary valve is open at this time), so that the air in the first cavity enters the lower cavity through the air guide hose, and the liquid in the lower cavity is squeezed out. Thanks to the design of the upper cavity and the lower cavity, the liquid can be temporarily stored in the lower cavity, and the discharge of the liquid is precisely controlled;

[0017] 3. When the double-hole valve is opened or closed, the double-hole valve body is rotated so that the double holes are aligned or offset between the upper cavity and the lower cavity, and at the same time, the round head of the first clamping block is rotated and clamped into the positioning groove of the first positioning plate, so that the double-hole valve can be kept in the open or closed state. The same is true when the single-hole valve is opened or closed. Thanks to the setting of the positioning mechanism, the convenience of using the double-hole valve and the single-hole valve is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Working principle:

[0039] When in use, add the liquid to be separated into the upper cavity 101 of the double cone funnel 1, then tighten the screw cap 10 to shake, and then wait for the liquid to be separated. After the liquid is separated, open the double-hole valve 2 (the single-hole valve 3 is closed at this time), and push the piston 8 through the pull rod 7 to compress the second cavity 602 (the rotary valve 9 is closed at this time), so that the air in the second cavity 602 enters the upper cavity 101 through the air guide hose 5, the connecting pipe 4 and one of the through holes between the upper cavity 101 and the lower cavity 102, and the liquid at the bottom of the upper cavity 101 is discharged.

When the lower cavity 102 is discharged, the double-hole valve 2 is rotated to close, and the single-hole valve 3 is rotated to open. The piston 8 is pushed by the pull rod 7 to compress the first cavity 601 (the rotary valve 9 is opened at this time), so that the air in the first cavity 601 enters the lower cavity 102 through the air guide hose 5, and the liquid in the lower cavity 102 is squeezed out through the single hole at the bottom of the lower cavity 102;

[0040] When the double-hole valve 2 is opened or closed, the double-hole valve body 201 is rotated so that the double holes are aligned or offset with the double holes between the upper cavity 101 and the lower cavity 102, and at the same time, the round head of the first clamping block 203 is rotated and clamped into the positioning groove of the first positioning plate 202, so that the double-hole valve 2 can remain in the open or closed state. The same is true when the single-hole valve 3 is opened or closed.
