Description

Technical Field

[0001] This utility model belongs to the field of waste heat recovery technology, specifically relating to a waste heat recovery equipment management device. Background Technology

[0002] In the field of industrial energy management and energy conservation, waste heat recovery equipment is a key piece of equipment for achieving efficient energy utilization and reducing production energy consumption. Its core function is to improve overall energy efficiency by recovering and reusing the heat energy contained in heat-carrying media such as waste gas and wastewater generated during industrial production. Common waste heat recovery systems typically use a heat exchanger as the core, forming a closed-loop control circuit with supporting pipes, electric regulating valves, flow meters, and temperature sensors. An industrial control computer monitors and regulates the overall operation. The temperature sensor is responsible for real-time detection of the temperature of the medium within the pipes, providing crucial data support for flow regulation and heat exchange efficiency control.

[0003] However, a significant technical drawback exists in existing technologies: temperature sensors are generally fixed directly to the outer wall of the pipe using threaded connections or other detachable methods, requiring the probe end to be inserted into the pipe for accurate temperature detection. While this installation method ensures measurement accuracy, it necessitates stopping the waste heat recovery system and cutting off media flow when the temperature sensor is damaged, needs replacement, or requires periodic calibration. Disassembly can only proceed after the pressure and temperature inside the pipe have dropped to a safe range. This process not only prolongs system downtime and affects the continuity of waste heat recovery but also potentially leads to greater capacity losses due to temporary interruptions in the main production process. Utility Model Content

[0005] The technical solution of this utility model is as follows:

[0006] A waste heat recovery equipment management device includes an industrial control computer and an electric valve and a flow meter connected to the industrial control computer. It also includes a temperature monitoring component consisting of a connecting pipe and a temperature sensor. The temperature sensor is connected to the industrial control computer. The connecting pipe has a plug hole. The temperature sensor is detachably and sealedly connected to the plug hole. An elastic telescopic rod with a telescopic end sealed and inserted into the connecting pipe is fixed on the side of the connecting pipe. A sealing plug is provided on the telescopic end of the elastic telescopic rod. The sealing plug can be sealed and inserted into the plug hole.

[0007] Furthermore, the telescopic end of the elastic telescopic rod is provided with a connecting cover, and the sealing plug is disposed inside the connecting cover.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 3As shown, a waste heat recovery equipment management device includes a temperature monitoring component 3, an industrial control computer 5, and an electric valve 2 and a flow meter 4 connected to the industrial control computer 5. The industrial control computer 5 is connected to a display screen 6. The temperature monitoring component 3 consists of a connecting pipe 32 and a temperature sensor 31. The temperature sensor 31 is connected to the industrial control computer 5. The connecting pipe 32 has an insertion hole, and the temperature sensor 31 is detachably and sealedly connected to the insertion hole. An elastic telescopic rod 33 with a telescopic end sealed and inserted into the connecting pipe 32 is fixed on the side of the connecting pipe 32. A sealing plug 37 is provided on the telescopic end of the elastic telescopic rod 33, and the sealing plug 37 can be sealed and inserted into the insertion hole.

[0019] It should be noted that the industrial computer 5 is a DT-5206-A683 wall-mounted industrial computer. Correspondingly, the temperature sensor 31, electric valve 2, and flow meter 4 are all existing technologies and can be connected through corresponding cables according to actual connection needs.

[0020] It should be noted that the detachable sealed connection of the temperature sensor 31 is as follows: a pipe connector is welded and fixed at the insertion hole, the temperature sensor 31 is connected to the pipe connector by thread, and the connection between the pipe connector and the temperature sensor 31 can be sealed by wrapping sealing tape and adding a metal gasket.

[0021] It should be noted that the electric valve 2 is used for flow regulation and can be a proportional regulating solenoid valve, an electric ball valve, or other electric valve 2 capable of flow regulation.

[0022] In use, the connecting pipe 32, flow meter 4 and electric valve 2 are connected to the waste heat pipe 1. Then, the temperature sensor 31 detects the temperature data, the flow meter 4 detects the flow data, and the industrial control computer 5 controls the electric valve 2 to work based on the detected data in order to realize the management of waste heat recovery.

[0023] When the temperature sensor 31 needs to be removed, the operator rotates the temperature sensor 31, and the temperature sensor 31 gradually disengages from the pipe joint, while the sealing plug 37 gradually inserts into the insertion hole. After the sealing head is fully inserted into the insertion hole, the operator continues to rotate the temperature sensor 31 until the temperature sensor 31 is disengaged from the insertion hole.

[0024] When installation is required, follow the above procedure: insert the temperature sensor 31 into the socket and screw it into the pipe connector. During the screwing process, the temperature sensor 31 pushes the sealing plug 37 out of the socket.

[0025] In this embodiment, a connecting cover 34 is fixed to the telescopic end of the elastic telescopic rod 33, and a sealing plug 37 is fixed inside the connecting cover 34.

[0026] In this embodiment, the sealing plug 37 abuts against the abutment rod 35 fixed on the temperature sensor 31. The abutment rod 35 is provided to prevent the temperature sensor 31 from directly contacting the sealing plug 37, thereby ensuring detection.

[0027] In this embodiment, the connecting cover 34 and the sealing plug 37 are provided with a circular hole along the axial direction. A rotating disk 36 that is rotatably connected to the connecting cover 34 is provided in the circular hole, and the abutting rod 35 abuts against the rotating disk 36.

[0028] During use, the rotating disk 36 reduces the friction when the abutment rod 35 rotates.

[0029] In this embodiment, the industrial control computer 5 is connected to a display screen 6.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
