Description

Technical Field

[0001] The utility model belongs to the technical field of chemical electromechanical equipment, and in particular relates to an electronic temperature measuring device for a stirring tank. Background Art

[0002] During chemical synthesis production or experiments, the stirring function allows the materials to be fully dissolved and mixed. In order to better control the reaction process, most chemical synthesis stirring also requires monitoring and controlling the temperature changes of the materials to obtain the best product performance.

[0003] At present, chemical synthesis production basically adopts the oil bath method of jacketing the reactor to heat up, and the temperature sensing components are mostly installed in the jacket. Since the jacket layer in the heating area and the materials in the reactor are separated by the outer wall of the reactor, the temperature conduction between the heating area and the materials is delayed, resulting in temperature errors, making it difficult to accurately monitor and control the reaction temperature. If the temperature sensing component is installed on the inner wall of the reactor, if the installation is slightly improper, long-term stirring can easily cause the component to fall off and be damaged, resulting in production accidents.

[0004] When conducting chemical synthesis experiments in the laboratory, most of the time, a bracket is used to fix the temperature sensing components. The height of the temperature measuring probe needs to be adjusted according to the liquid level. If the position is not adjusted well, it will affect both the stirring function and the accuracy of the temperature measurement.

[0005] The utility model "A temperature-measurable stirring head and agitator" with application number 202021180372.4 provides a solution for temperature-measurable stirring heads and agitators. However, due to non-electronic temperature measurement, it cannot communicate with the host computer. The utility model "A flush temperature measuring device for measuring the temperature of a small mixing tank" with application number 202320713210.X utilizes improvements to the mixing tank to achieve the function of detecting the temperature of the material inside the tank without affecting the operation of other equipment inside the mixing tank. The first two are both new concepts and designs, mainly for laboratory experiments, and cannot provide good support for industrial production. At the same time, the functions described cannot be achieved by simply modifying or combining the current commercially available equipment.

[0006] Therefore, it is extremely necessary to provide a method and device suitable for both industrial production and laboratory working conditions, which can realize data communication with a host computer without affecting the stirring function, and can be used for measuring the temperature of a stirring tank by modifying or combining with existing equipment.

[0007] In view of the above problems, this application proposes a simple and feasible solution. Utility Model Content

[0008] The purpose of the utility model is to provide an electronic temperature measuring device for a stirring tank that is suitable for both industrial production and laboratory experiments and can communicate data with a host computer. At the same time, it can also be achieved by modifying and assembling commercially available finished parts.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions.

[0011] Furthermore, the stirring motor is installed and fixed on the stirring motor bracket.

[0012] Furthermore, the stirring rod is connected and installed on the rotating shaft of the stirring motor.

[0013] Furthermore, the temperature measuring probe is an electronic chip type temperature measuring element, and has a temperature measuring probe electrical signal line led out, and the temperature measuring probe is installed and fixed at the lower end of the stirring rod.

[0014] Furthermore, the wire groove is longitudinally parallel to the stirring rod and is arranged in the curved surface of the stirring rod, and the electrical signal line of the temperature measuring probe from the lower end of the stirring rod is laid in the wire groove.

[0015] Furthermore, the conductive slip ring assembly consists of two parts: a conductive slip ring stator and a conductive slip ring rotor; the conductive slip ring rotor is provided with a plurality of independent rotor collector rings with conductivity, each circle of rotor collector rings and the corresponding independent rotor terminal are connected and conducted by a conductive collector ring wire, and the temperature probe electrical signal line is connected to the rotor terminal; the conductive slip ring stator is provided with a plurality of independent stator reeds with conductivity, and each stator reed is elastically contacted and conducted with the corresponding independent rotor collector ring.

[0016] Furthermore, the conductive slip ring rotor is fixed on the stirring rod and rotates together with the stirring rod.

[0017] Furthermore, the stator spring is connected to a host computer communication line to achieve communication between the temperature measuring probe and the host computer.

[0018] Furthermore, the conductive slip ring stator of the conductive slip ring assembly is fixedly mounted on a fixed bracket.

[0019] Furthermore, the fixed bracket is connected and fixed to the stirring motor bracket.

[0020] Furthermore, the conductive slip ring assembly may be a commercially available finished product having the same function as that described herein.

[0021] To sum up, the utility model fixes the temperature measuring probe at the lower end of the stirring rod, and its electrical signal is connected to the rotor terminal through the temperature measuring probe electrical signal line, and then conducted by the collector ring wire and the rotor collector ring, and then connected to the host computer via the stator reed elastically connected and conducted with the rotor collector ring and the host computer communication line, thereby realizing the communication between the temperature measuring probe electrical signal and the host computer.

[0022] The beneficial effects of the utility model are as follows: the temperature measuring probe and the stirring rod rotate together, and the electrical signal is transmitted through the conductive slip ring assembly, thereby realizing the temperature monitoring of the material in the stirring tank and the transmission of the electrical signal.
