Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of monitoring devices, in particular to a monitoring device for rubber production vulcanization reaction. Background Art
[0002] Vulcanization reaction is an important process in rubber production. It involves a chemical reaction between rubber and sulfur. The purpose of this reaction is to improve the performance of rubber, such as enhancing its heat resistance, aging resistance, compression resistance and tensile strength. In the vulcanization reaction, the unsaturated bonds in the rubber react with sulfur to form a cross-linked structure. This cross-linked structure forms a "net-like" structure between the rubber molecules, thereby significantly improving the performance of the rubber. During the vulcanization reaction, it is usually necessary to monitor data such as the temperature and pressure of the vulcanization reaction to ensure the normal progress of the vulcanization reaction.
[0003] In the prior art, temperature sensors are usually used to monitor the temperature of rubber vulcanization reactions. However, the range of temperature detection is not comprehensive enough and can only detect the temperature of one point. In addition, the existing temperature sensors are fixed on the reaction box and are not easy to replace when damaged. The vulcanization reaction releases toxic gases during the reaction. The existing monitoring device does not take protective measures when the reaction box leaks, and it is impossible to take out samples for real-time monitoring during the reaction. Therefore, a rubber production vulcanization reaction monitoring device is proposed to address the above problems. Summary of the invention

[0010] Preferably, the number of the box door, the fixed plate, the piston cylinder and the piston rod are all two, and one side of the box door is fixedly connected to the piston rod.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. In the utility model, by providing a sleeve, a threaded ring, a threaded barrel and a temperature sensor, when the temperature sensor is damaged, the temperature sensor can be replaced more conveniently. The multiple temperature sensors provided can monitor the temperature in the reaction process in a wider range. When the temperature sensor is damaged, the threaded barrel can be directly unscrewed from the outside of the threaded ring to remove the temperature sensor, and then a new temperature sensor is inserted into the inside of the sleeve, and the threaded barrel is tightened on the outside of the threaded ring to complete the replacement of the temperature sensor.
[0013] 2. In the utility model, by setting the connecting pipe, the first ball valve, the sampling pipe, the second ball valve, the sampling tank, the discharge pipe and the discharge valve, the material can be sampled during the reaction process, and the reaction status of the current material can be monitored in real time. When the reaction starts, the first ball valve and the second ball valve are opened, and the discharge valve is closed, and then heating and pressurization are performed. When sampling is required, the first ball valve is closed, and the discharge valve is opened. The material enters the sampling tank through the sampling pipe under the action of pressure. When the material flows out through the discharge pipe and the discharge valve, the material is collected for detection, the discharge valve is closed, and the first ball valve is opened. At this time, the reaction box, the connecting pipe, the sampling tank and the sampling tube are connected, and the pressure is balanced. The material inside the sampling tank flows back to the inside of the reaction box due to gravity. Then the first ball valve and the second ball valve are closed, and the discharge valve is opened. Since the pressure inside the reaction tank is relatively large, the material remaining inside the discharge pipe can be pressed out, thereby completing the real-time sampling without residue, so that the user can more comprehensively detect the material status in the reaction;
