Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a reflux condenser for a distillation kettle. Background Art

[0002] The function of a still is to vaporize the liquid being distilled. In the chemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In the distillation process, the device that converts vapor into liquid is also called a condenser. All condensers operate by taking away the heat of gas or vapor. In the chemical industry, stills are used in conjunction with condensers.

[0003] In response to this, the utility model patent with the authorization announcement number CN210165798U discloses a vertical safety reflux condenser. Chilled water is used as the cooling medium. It enters the shell from the chilled water inlet and exits the shell from the chilled water outlet. A partition is designed between the shells to force the chilled water into a turbulent state, enhance heat exchange, and heat is transferred from the external cooling pipe; the process medium enters the pipe from the process medium inlet, and the non-condensable gas rises along the inner cooling pipe, is collected by the non-condensable gas end cover, and is led out from the non-condensable gas outlet by the vacuum pump; the process medium condensed along the inner tube drips on the reflux end cover under the action of gravity, and flows back into the system from the process medium outlet. This adopts a pure countercurrent high-efficiency heat exchange flow mode. It is inevitable that there is air between the shells when it is used for the first time, so the exhaust port is used to exhaust the air.

[0004] However, the condenser in the above patent still has some problems: when the condenser is in use, the hot steam rises and encounters the cooling of the condenser tube. The hot steam rises too quickly, which may lead to incomplete condensation of the product and cause resource loss. At the same time, the condenser is prone to instability when installed on the distillation kettle. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a reflux condenser for a distillation kettle to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model proposes a reflux condenser for a distillation kettle, comprising an outer condensation tube, a condensation coil is fixedly arranged inside the outer condensation tube, an auxiliary support mechanism is arranged on the outer wall of the outer condensation tube, and an upper end cover is installed on the top of the outer condensation tube;

[0007] A mounting plate is fixedly provided in the middle of one side of the upper end cover, a blower is installed on the top of the mounting plate, an air outlet end of the blower is fixedly connected to an air supply pipe, one end of the air supply pipe is fixedly connected to an air supply pipe, one end of the air supply pipe is fixedly connected to an air dispersion hopper, an air collecting hopper is fixedly provided at the bottom of the inner wall of the upper end cover, one side of the air collecting hopper is fixedly connected to one end of the air dispersion hopper, and a plurality of evenly distributed one-way valves are installed on the surface of the air collecting hopper, a guide hopper is fixedly provided on the top of the inner wall of the upper end cover, and an electromagnetic valve is fixedly connected between the guide hopper and the air collecting hopper.

[0008] In one example, the top end of the upper end cover is fixedly connected to an air outlet, the bottom end of the condensation outer tube is installed with a lower end cover, and the bottom end of the lower end cover is fixedly connected to an air inlet.

[0009] In one example, one end of the condensing coil is fixedly connected to a water inlet, and the other end of the condensing coil is fixedly connected to a water outlet.

[0010] In one example, the auxiliary support mechanism includes a movable sleeve, and fixing knobs are threadedly connected in the fixing screw holes on both sides of the movable sleeve, connecting angle plates are fixed at both ends of the movable sleeve, and a first fixing block is fixed on one side of each connecting angle plate.

[0011] In one example, an adjustment screw is threadedly connected to an adjustment screw hole opened in the middle of the top of the first fixed block, and the bottom end of the adjustment screw is rotatably connected to a second fixed block. A mounting angle plate is fixedly provided on one side of the second fixed block, and a plurality of evenly distributed mounting holes are opened on the top of the mounting angle plate. Limiting strips are provided on both sides of the top of the second fixed block and are interlaced with the limiting holes opened on both sides of the bottom end of the corresponding first fixed block.

[0015] 2. The distillation kettle uses a reflux condenser, and an auxiliary supporting mechanism is arranged on the outer wall of the condensation outer tube. The connecting angle plate connected by the movable sleeve is connected to the first fixed block.
