[0002] As an important chemical raw material, guaiacol is widely used in medicine, dyes, fragrances and other fields.

[0003] In the patent document with the announcement number CN220582765U, a guaiacol feed heatable pipeline is disclosed, including a feed pipe, the top of the feed pipe is connected with a feed valve, the top of the feed valve is connected with a straight pipe, the end of the straight pipe away from the feed valve is connected with a first three-way pipe, both ends of the first three-way pipe are connected with a delivery pipe, the center end of the top of the first three-way pipe is fixedly connected with a mounting seat, and the surfaces of the two groups of delivery pipes are provided with heating components. By setting the heating component, the temperature of the guaiacol raw material flowing through the first three-way pipe is monitored in real time by a temperature sensor, the electric heater provides a heat source, and then the insulation sleeve, the heat conduction hole, the warning light, the connecting wire, the annular heating rack, the electric heating ring and the electric heating pipe are matched to realize the heating and crystallization prevention function of the guaiacol raw material in the delivery state in the two groups of delivery pipes, so as to prevent the guaiacol raw material from crystallizing below 25°, thereby reducing the waste of the guaiacol raw material and the subsequent cleaning trouble.

[0004] In actual use of the above device, since steam may be generated during the heating process of guaiacol, the above pipeline cannot discharge the accumulation and high pressure of steam in time, which poses a potential explosion safety hazard. For this reason, the present application provides a three-way pipeline with heating for feeding guaiacol preparation. Utility Model Content

[0005] The utility model aims to provide a three-way pipeline with heating for feeding guaiacol preparation, which solves the problems raised in the background technology.

[0006] The embodiment of the present application provides a three-way pipeline for preparing guaiacol with heating, comprising a feed pipe, the top of the feed pipe is connected to an electrically controlled feed valve, the top of the electrically controlled feed valve is connected to a straight pipe, the top of the straight pipe is connected to a three-way pipe, both ends of the three-way pipe are connected to electric heating delivery pipes, the feed end of the electric heating delivery pipe is fixedly installed with a feed valve, the outer surface of the electric heating delivery pipe is fixedly installed with a mounting frame, the interior of the mounting frame is fixedly installed with a pressure monitor, the top of the electric heating delivery pipe is fixedly installed with a pressure relief pipe, the interior of the pressure relief pipe is fixedly installed with an electrically controlled pressure relief valve, the top of the three-way pipe is fixedly installed with a bracket, the top of the bracket is fixedly installed with a controller, the pressure monitor is signal-connected to the controller, and the control ends of the electrically controlled pressure relief valve and the feed valve are both electrically connected to the controller.

At the same time, the pressure monitor continuously monitors the pressure in the electric heating delivery pipe. When the pressure exceeds the preset safety threshold, the pressure monitor sends a signal to the controller. After receiving the over-pressure signal, the controller immediately starts the electronically controlled pressure relief valve to release part of the pressure in the electric heating delivery pipe through the pressure relief pipe, which is beneficial to improve the safety of the device during operation.

[0014] Optionally, a temperature sensor is embedded in the inner cavity of the three-way pipe, and the temperature sensor is electrically connected to the controller.

[0015] By adopting the above technical solution, the temperature of hydroxychloroquine is monitored by a temperature sensor, which is conducive to ensuring that hydroxychloroquine is transported within a suitable temperature range.

[0016] Optionally, a plurality of groups of reinforcing ribs are fixedly mounted on the inner wall of the protective layer.

[0017] By adopting the above technical solution, the strength and stability of the protective layer can be improved by reinforcing the ribs, thereby improving the explosion-proof effect of the electric heating conveying pipe when in use.

When guaiacol passes through the electric heating delivery pipe, the electric heating delivery pipe heats it. At the same time, the pressure monitor continuously monitors the pressure in the electric heating delivery pipe. When the pressure exceeds the preset safety threshold, the pressure monitor sends a signal to the controller. After receiving the high pressure signal, the controller immediately starts the electronically controlled pressure relief valve to release part of the pressure in the electric heating delivery pipe through the pressure relief pipe, which is beneficial to improve the safety of the device during operation.

[0022] 2. The inner tube directly contacts and transports guaiacol. It uses corrosion-resistant materials and provides heating function for the inner tube through the electric heating layer to ensure that the guaiacol maintains a suitable temperature during transportation.
