Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, and particularly relates to a universal liftable and rotatable separating funnel rack. Background Art

[0002] A separating funnel is a commonly used experimental device in laboratories, mainly used for liquid-liquid extraction and liquid-liquid separation. Its principle relies on the density difference between two immiscible liquids in the separating funnel, and the separation of the two liquids is achieved through gravity separation. A separating funnel rack is a rack for placing separating funnels. The initial design of the separating funnel rack was simple and had a single function, mainly meeting basic experimental needs. With the increasing complexity and precision requirements of chemical experiments, the design of the separating funnel rack has been continuously improved and upgraded.

[0003] Traditional separating funnel racks are usually fixed, unable to adjust the height and angle. When in use, it is necessary to adjust the height of the experimental bench according to experimental needs or bend down to operate by oneself, which is not only inconvenient but also likely to cause unstable experimental operations and affect experimental results. Moreover, traditional separating funnel racks have poor stability during use, prone to shaking or tilting, affecting the accuracy of experimental operations. Summary of the Utility Model

[0004] Aiming at the above deficiencies in the prior art, a universal liftable and rotatable separating funnel rack provided by the utility model solves the problems of inability to adjust the height and angle and poor stability in the prior art.

[0005] To achieve the above utility model purpose, the technical solution adopted by the utility model is: a universal liftable and rotatable separating funnel rack, including a funnel tray, a hydraulic rod arranged at the bottom of the funnel tray, and a base arranged at the bottom of the hydraulic rod. The funnel tray and the hydraulic rod are rotatably connected through a bearing;

[0006] The funnel tray is provided with a first placement hole, a second placement hole, and a third placement hole; the first placement hole and the second placement hole are arranged at the edge of the funnel tray, and the third placement hole is arranged at intervals between the first placement hole and the second placement hole; a locking mechanism is arranged on the first placement hole. The locking mechanism includes a fixing plate fixedly arranged on the funnel tray, and two symmetrical clamping rings are movably arranged on the fixing plate. The clamping rings and the fixing plate are connected through a telescopic cylinder.

[0007] The beneficial effects of the present utility model are as follows: Through the design of the hydraulic rod, the user can easily adjust the height of the funnel tray to adapt to the requirements of different working scenarios, improving the flexibility and convenience of operation. The base at the bottom of the hydraulic rod is stable and reliable, providing a solid support for the entire structure and ensuring the stability and safety during the operation process. The funnel tray and the hydraulic rod are rotationally connected through a bearing. During operation, the separating funnel to be processed can be rotated to the user's direct front by turning. The locking mechanism starts the telescopic cylinder, which drives two clamping rings to move, enabling the clamping rings to clamp the wall of the separating funnel, effectively preventing the separating funnel from shaking or falling off during the operation process; by changing the opening amplitude of the clamping rings of the locking mechanism, separating funnels of different specifications can be clamped, making the placement holes more versatile. The first placement hole, the second placement hole, and the third placement hole are provided, which are suitable for separating funnels of various different models.

[0008] Further, for the above-mentioned universal liftable and rotatable separating funnel rack, a silica gel pad is provided at the edge of the clamping ring.

[0009] The beneficial effect of adopting the above further scheme is that: The silica gel material is soft and has a certain elasticity, which can effectively relieve the pressure of the clamping ring on the wall of the separating funnel, reducing the risk of the separating funnel cracking caused by excessive clamping force.

[0010] Further, the diameters of the first placement hole and the second placement hole are 8.5 cm; the diameter of the third placement hole is 7.4 cm.

[0011] The beneficial effect of adopting the above further scheme is that: The first placement hole is used to place a 2L separating funnel, and its stability is maintained through the locking mechanism; the second placement hole is used to place a 1L separating funnel, and it can be made stable without the locking mechanism; the third placement hole is used to place a 250ml separating funnel. The third placement hole is arranged at intervals between the first placement hole and the second placement hole, facilitating the observation of the liquid level of the separating funnel.

[0012] Further, for the above-mentioned universal liftable and rotatable separating funnel rack, a marking plate is provided on the sides of the first placement hole, the second placement hole, and the third placement hole.

[0013] The beneficial effect of adopting the above further scheme is that: By setting the marking plate, the specification information of each placement hole can be intuitively displayed, helping the experimenter quickly and accurately select the suitable placement hole, improving the convenience and efficiency of the experimental operation.

[0014] Further, for the above-mentioned universal liftable and rotatable separating funnel rack, the base includes five brackets connected to the hydraulic rod and a circular support rod provided at the ends of the five brackets.

[0015] The beneficial effects of adopting the above further solution are as follows: By using five brackets and the circular struts arranged at the ends of the five brackets, the total weight of the device can be reduced.

[0016] Further, for the above-mentioned general-purpose liftable and rotatable separating funnel rack, the hydraulic rod includes an oil cylinder fixedly connected to the base and a piston rod movably connected to the funnel tray. A piston is provided at the end of the piston rod, and the piston is movably arranged inside the oil cylinder. A seal is provided on the piston, and a start button is provided outside the piston.

[0017] The beneficial effects of adopting the above further solution are as follows: The hydraulic rod controls the movement of the piston through the hydraulic principle to achieve the height adjustment of the funnel tray. The oil cylinder is fixedly connected to the base, and the piston rod is movably connected to the funnel tray. Press the start button, and the lifting function is achieved through the pushing and pulling movement of the piston. The seal provided on the piston can effectively prevent the leakage of the hydraulic system and ensure the stable operation of the hydraulic rod.

[0018] The beneficial effects of the present utility model are as follows: Through the design of the hydraulic rod and the bearing, the lift and rotation functions of the funnel tray are realized, making the experimental operation more flexible and convenient. Multiple types of placement holes are provided on the funnel tray, which can accommodate separating funnels of various different specifications, improving the versatility and applicability of the equipment. The locking mechanism includes a fixing plate, a clamping ring, and a telescopic cylinder. Through the design of the clamping ring and the setting of the silicone pad, the separating funnel can be effectively fixed to prevent sliding and tilting, ensuring the stability and safety of the experimental operation.
