Description

Technical Field

[0001] This utility model is a separatory funnel assembly for extraction, belonging to the field of extraction equipment. Background Technology

[0002] Separatory funnels are used to hold mixed solutions to be extracted. They are typically pear-shaped, a design that increases the contact area between the liquids, facilitating the distribution of solute between different solvents during extraction. Adding an observation window to the separatory funnel allows researchers to easily observe the separation of adjacent solute layers within the funnel. The observation window is primarily made of transparent glass; however, after a period of use, the surface of the glass easily becomes stained and needs to be removed for cleaning. Currently, the observation window is fixed to the separatory funnel with screws. Specifically, the screw passes through the frame used to secure the transparent glass and then connects to the screw hole on the separatory funnel. However, because the screws require frequent removal and installation, the screw hole on the separatory funnel is prone to damage such as misalignment. Once the screw hole is damaged, the observation window cannot be properly installed on the separatory funnel, which not only affects experimental operations but also increases maintenance costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide an extraction separatory funnel assembly to solve the problems mentioned in the background section. This invention eliminates the need to machine the screw hole that mates with the screw onto the separatory funnel, and eliminates the need to replace the separatory funnel when the screw hole is damaged, thus reducing maintenance costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an extraction separatory funnel assembly, comprising a separatory funnel, a valve installed at the bottom of the separatory funnel, a rectangular opening on the annular side of the separatory funnel, a frame for connection and fixation to the separatory funnel on the outer side of the rectangular opening, a transparent glass being inserted into the frame, a pressure frame for limiting the position of the transparent glass being provided on the side of the frame away from the separatory funnel, slots being provided on two parallel sides of the frame, insert plates being inserted into the slots, a plurality of small holes being provided on one side of the frame, a plurality of round holes aligned with the small holes being provided on the side of the frame away from the separatory funnel, the round holes communicating with the slots, a plurality of screw holes being provided on one side of the insert plate, a first screw being inserted into the small hole, one end of the first screw passing through the round hole and threaded into the screw hole.

[0005] Furthermore, a sealing washer is provided between the pressure frame and the frame, and the first screw passes through the sealing washer.

[0006] Furthermore, a collection groove is provided on the lower side of the frame, and both ends of the collection groove are connected to the separating funnel by a second screw.

[0007] Furthermore, connecting plates are installed at both ends of the collection tank, and a protrusion is provided between the connecting plate and the separating funnel. The protrusion is connected and fixed to the separating funnel, and the second screw passes through the connecting plate and is threadedly connected to the protrusion.

[0008] Furthermore, a storage groove is formed by a recess on the side of the frame away from the rectangular opening, and the transparent glass is inserted into the storage groove. The depth of the storage groove is the same as the thickness of the transparent glass.

[0009] Furthermore, a top cover is snapped onto the upper end of the separating funnel, an inlet pipe connector is installed on the upper surface of the top cover, and a side cover is hinged to one edge of the upper surface of the top cover.

[0010] Furthermore, a support rod is installed on the liquid inlet pipe connector by means of a clamp, and a connecting seat is installed on the end of the support rod away from the liquid inlet pipe connector. A plurality of first fixing holes are evenly opened on one side of the connecting seat.

[0011] Furthermore, a positioning seat is provided on the annular side of the separating funnel away from the rectangular opening, and multiple connecting rods are installed between the positioning seat and the separating funnel. Multiple second fixing holes are evenly opened on one side of the positioning seat.

[0012] The beneficial effects of this utility model are: 1. Insert the insert plate with the machined screw hole into the slot on the frame, and then extend the first screw through the frame into the slot and thread it into the screw hole. At this time, the pressure frame and the frame cooperate with each other to restrict the position of the transparent glass. When the screw hole is damaged due to misalignment or other reasons, remove the damaged insert plate from the slot and replace it. Compared with the method of machining the screw hole on the separatory funnel, there is no need to replace the separatory funnel when the screw hole is damaged, which reduces maintenance costs.

[0013] 2. After removing the transparent glass, the solute flowing out from the channel formed by the rectangular opening and the frame will flow into the collection tank, thus collecting the outflowing solute in a concentrated manner and preventing the solute from dripping randomly from the channel formed by the rectangular opening and the frame.

[0014] 3. After the second screw passes through the connecting plate, it is threadedly connected to the protrusion to complete the assembly of the collecting tank and the separating funnel, which facilitates the assembly and disassembly of the collecting tank and the separating funnel. The protrusion locally increases the thickness of the part of the separating funnel where the second screw is installed. Attached Figure Description

[0018] See Figures 1-3 The separatory funnel 1 has a rectangular opening on its annular side. A frame 14 is provided on the outside of the rectangular opening and is connected and fixed to the separatory funnel 1. A transparent glass 13 is inserted into the frame 14. The side of the frame 14 away from the rectangular opening is recessed to form a storage groove 20. The transparent glass 13 is inserted into the storage groove 20. The depth of the storage groove 20 is the same as the thickness of the transparent glass 13. A pressure frame 11 is provided on the side of the frame 14 away from the separatory funnel 1 to limit the position of the transparent glass 13. A sealing gasket 19 is provided between the pressure frame 11 and the frame 14, so that the first screw 12 passes through the sealing gasket 19 to prevent the solute from leaking from the installation part of the transparent glass 13.

[0019] See Figures 1-4The frame 14 has slots 21 on two parallel sides, and insert plates 18 are inserted into the slots 21. One side of the frame 14 has multiple small holes, and the side of the frame 14 away from the separating funnel 1 has multiple round holes aligned with the small holes. The round holes communicate with the slots 21. One side of the insert plate 18 has multiple screw holes, and a first screw 12 is inserted into the small hole.
