Description

Technical Field

[0001] The utility model relates to a common tool for chemistry, chemical engineering teaching experiments and scientific research, in particular to a reaction kettle transfer clamp. Background Art

[0002] In chemical experiment teaching and scientific research, in order to achieve experimental conditions, it is often necessary to place the reactor in a high-temperature furnace to achieve high-temperature, high-pressure and other reactions. When placing the reactor in the high-temperature furnace and taking it out of the high-temperature furnace, it is necessary to use tools to clamp the outer wall of the reactor to complete the placement and removal. Especially after the reaction is completed, the high-temperature furnace and the reactor are still in a high-temperature state. If the reactor cannot be effectively clamped and fixed, scalding accidents are very likely to occur. In the laboratory, crucible tongs are generally used as placement and removal tools to complete experimental operations. Due to the structural reasons of the crucible tongs, the contact surface with the reactor is small. When the crucible tongs move the reactor, it cannot be effectively fixed, and it is easy to tip over, which affects the mixing method of the reaction materials in the reactor. In addition, due to the weight of the reactor, the operator not only needs to overcome the grip force exerted by the weight of the reactor to clamp the reactor, but also needs to pay attention to the residual temperature of the experimental environment to avoid scalding, and the safety of the experiment cannot be guaranteed. Utility Model Content

[0003] In order to solve the above problems, the utility model discloses a reaction kettle removal clamp.

[0004] The specific technical solutions are as follows:

[0005] A reactor removal clamp is provided with a handle, the front end of the handle is rectangular, the rectangular portion is fixedly connected to a fixing frame, a threaded rod is rotated to pass through a threaded hole in the rectangular portion of the handle and is locked by a limit ring, two strip frame sides are relatively arranged in the fixing frame, and fixing bolts are screwed in the strip frame and the fixing frame to connect the strip frame and the fixing frame together.

[0006] The fixing frame is composed of two groups of limiting plates, which are arranged up and down and fixed together with the handle, and the upper limiting plate is provided with a sliding groove.

[0007] The middle part of the rotating threaded rod is processed with an annular limiting groove with the same width as the rectangular end of the handle, and the outer ends of the two annular limiting grooves are respectively processed with positive and reverse threads.

[0008] The strip frame is in a U-shaped structure, and a fixing hole is arranged on the upper plane of the strip frame, and the fixing bolts are screwed into the sliding groove and the fixing hole of the fixing frame.

[0009] The advantages of the utility model are as follows: by utilizing the margin between the outer edge of the sealing flange of the reactor and the fixing part, the slot opening of the device is clamped on the flange plate surface of the reactor with a certain margin, thereby increasing the contact area between the removal clamp and the reactor, and achieving stable placement and removal operations of the reactor. When removing the reactor of the same model, the distance between the two slots is moved by rotating the threaded rod. When the flange of the reactor can be placed in the slot opening of the device, the fixing nut is tightened. In the experiment, it is no longer necessary to consider the gripping force applied to ensure the stability of the clamping. The structural design of the slot The movable space for the reactor to be removed is fixed, and the slot is stuck at the upper end of the reactor, and the center of gravity is moved downward, which can effectively avoid the occurrence of tipping. When removing reactors of different models, the fixed flange diameters are the same, and there is no need to readjust the spacing. When the flange diameter changes, the distance between the two slots is moved by rotating the threaded rod, and the fixing nut is tightened to fix it. The length of the handle grip is extended, and it can be operated even if the residual temperature is high. At the same time, the rotating screw is set on the outside of the strip frame to ensure that the experimenter is effectively separated from the reactor, preventing the experimenter from being scalded when operating the device.
