Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyanomethylene tri-n-butylphosphine production technology, and in particular to a cyanomethylene tri-n-butylphosphine synthesis reactor. Background Technology
[0002] Cyanomethylene tri-n-butylphosphine is an important organophosphine compound. Quaternary phosphine salts synthesized from tributylphosphine are high-performance surfactants with a wide pH adaptability and low foaming properties. They are also highly efficient, broad-spectrum, and low-toxicity bactericides. The complexes formed by cyanomethylene tri-n-butylphosphine with many transition metal elements are crucial catalysts. In the polyurethane industry, it is an excellent catalyst for the trimerization of isocyanates. Furthermore, cyanomethylene tri-n-butylphosphine can also be used as an extractant, fuel additive, and organic synthesis reagent.
[0003] Currently, the production of cyanomethylene tri-n-butylphosphine mostly involves mixing and reacting various raw materials in a synthesis reactor. Existing synthesis reactors mainly consist of a tank, inlet pipe, outlet pipe, sampling pipe, valve, and stirring mechanism. For example, Chinese Patent Publication No. CN220345842U discloses a chemical synthesis reactor with a heat preservation function. In this reactor, workers measure the temperature of the liquid by first opening the valve on the sampling pipe, then taking a sample through the sampling pipe, and finally measuring the temperature of the sample liquid with a thermometer. However, because manual sampling and temperature measurement are required, the process is quite cumbersome. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that existing synthesis reactors mainly consist of a tank, an inlet pipe, an outlet pipe, a sampling pipe, a valve, and a stirring mechanism. In these reactors, workers first open the valve on the sampling pipe to measure the temperature of the liquid inside the reactor, then take a sample through the sampling pipe and measure the temperature of the sample liquid using a thermometer. However, the manual sampling and temperature measurement by workers is cumbersome. Therefore, this invention proposes a cyanomethylene tri-n-butylphosphine synthesis reactor.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The stirring blade 35 is driven to rotate by the drive motor 32, and the raw materials in the tank 1 can be stirred by the rotating stirring blade 35.
[0028] The liquid extraction mechanism 8 includes a first U-shaped plate 81. The left side of the first U-shaped plate 81 is fixedly connected to the right side of the tank 1.

The surface of the first piston block 84 is in contact with the inner wall of the liquid inlet pipe 5. The upper surface of the first U-shaped plate 81 is fixedly connected to the bottom of the measuring mechanism 10. The first piston block 84 is controlled to move left and right by the first electric push rod 82. When the first piston block 84 moves to the right, the liquid in the tank 1 is drawn into the horizontal pipe 7 by the first piston block 84.

Furthermore, when the second electric push rod 102 controls the thermometer 104 to move up and down, the cleaning brush 13 can clean the reading surface of the thermometer 104, thereby preventing the thermometer 104 reading from being difficult to observe due to dust sticking to the reading surface of the thermometer 104.
[0032] In this invention, when using the synthesis reactor, the user first opens the valve 6 on the inlet pipe 5 and feeds the raw materials into the tank 1 through the inlet pipe 5. After the raw materials are fed in, the valve 6 is closed, and the drive motor 32 is turned on to rotate the stirring blades 35. At this time, the stirring blades 35 agitate the raw materials in the tank 1, causing the synthesis reaction of multiple raw materials in the tank 1.

At this time, the temperature of the liquid in the horizontal tube 7 is measured by the thermometer 104. After the temperature measurement is completed, the thermometer 104 is returned to the initial position by the second electric push rod 102. Then, the first piston block 84 is returned to the initial position by the first electric push rod 82, and the liquid in the horizontal tube 7 is pushed into the tank 1 by the first piston block 84. After the raw material synthesis reaction is completed, the material after the synthesis reaction is discharged through the liquid outlet pipe 4 by opening the valve 6 on the liquid outlet pipe 4.
