Problems solved by technology
[0002] The condensing reflux device commonly used in the existing laboratory needs to be connected to a water source to cool its continuous flow water supply when it is working. It needs to be connected to a long inlet and outlet pipe, and it needs to pass through a fume hood, which is very inconvenient; sometimes the water pressure is high, which will cause leakage and water pipes. Accidents such as falling off
Chinese patent ZL200920072957.1 has a simple structure, but due to poor sealing, it is not suitable for long-term condensation and reflux, and the solution will have a large quality loss

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] Such as figure 1 As shown, a condensing reflux device consists of a condensing reflux pipe 2 and a ground-neck Erlenmeyer flask 1. When the condensing reflux device works, the lower port of the condensing reflux pipe 2 is inserted into the grinding port of the ground-mouthed Erlenmeyer flask 1, and is sealed with it.
[0020] Such as figure 2 As shown, the condensation return pipe 2 is composed of the condensation outer pipe 4, the condensation inner pipe 5 and the inner and outer pipe wall connectors 3; the condensation inner pipe 5 is placed in the condensation outer pipe 4, and the lower end of the condensation inner pipe 5 and the condensation outer pipe 4 is closed connected, the upper end is open, and a cooling water cavity 6 for storing cooling water is formed between the condensing outer tube 4 and the condensing inner tube 5 . In or...

The invention relates to a condensation reflux device, a condensation reflux pipe comprises a condensation outer pipe and a condensation inner pipe; the condensation inner pipe is arranged in the condensation outer pipe, the lower ends of the condensation inner pipe and the condensation outer pipe are in closed connection, the upper ends are open, a cooling water cavity is formed between the condensation inner pipe and the condensation outer pipe, and is for condensation reflux after heat exchange of steam and cooling water; the upper ends of the condensation inner pipe and the condensation outer pipe are in fixed connection by inner and outer pipe wall connecting piece; the condensation inner pipe is a straight pipe or scaling pip or spiral pipe, the inner and outer pipe wall connecting piece is tiepieces for connecting the condensation inner pipe and the condensation outer pipe, the number of the tiepieces is greater than or equal to 2; or, the inner and outer pipe wall connecting piece is a circular plate for connecting the condensation inner pipe and the condensation outer pipe, and the circular plate is provided with a hole for flowing steam out and pouring the cooling water out after a test. The condensation reflux device is simple in structure and easy in operation, can perform condensation reflux without steady flowing water supply, and saves the cooling water, and the condensation effect is obvious; and the condensation inner pipe and the condensation outer pipe are in six combination ways, and can adapt to different test conditions.
Description
technical field [0001] The invention relates to a chemical equipment glass instrument, in particular to a condensation reflux device. Background technique [0002] The condensing reflux device commonly used in the existing laboratory needs to be connected to a water source to cool its continuous flow water supply when it is working. It needs to be connected to a long inlet and outlet pipe, and it needs to pass through a fume hood, which is very inconvenient; sometimes the water pressure is high, which will cause leakage and water pipes. Accidents such as falling off. Chinese patent ZL200920072957.1 has a simple structure, but due to poor sealing, it is not suitable for long-term condensation and reflux, and the solution will have a large quality loss. Therefore, the laboratory needs a condensing reflux device with a simple structure and a long duration. Contents of the invention [0003] In order to overcome the deficiencies of the prior art above, the present invention ...
