Description

Technical Field

[0001] This utility model relates to the field of pure water heating, and in particular to a pure water heating device. Background Technology

[0002] Pure water heating devices have wide applications in scientific research, medical treatment, and industrial production. In actual use, the input pure water temperature often varies significantly. When the input pure water temperature is low, the heating module needs to consume more energy to raise the water temperature to the target value. This not only reduces heating efficiency and increases energy consumption, but also results in inconsistent output pure water temperatures due to continuous inconsistent input temperatures, affecting subsequent manufacturing processes or experiments. More seriously, the thermal stress caused by temperature differences may subject the heating module to excessive pressure, accelerating aging or even damage, affecting the stability and lifespan of the equipment.

[0003] To address this issue, some existing pure water heating devices have attempted to improve heating efficiency and protect the heating module by adding insulation layers, optimizing the heating module structure, or introducing temperature control systems. However, these measures often have limited effectiveness and cannot fundamentally solve the problem caused by differences in the input pure water temperature. Utility Model Content

[0004] The main purpose of this utility model is to provide a pure water heating device, which aims to solve the technical problem of large temperature differences in the input pure water.

[0005] To achieve the above objectives, this utility model provides a pure water heating device, comprising: a water inlet mechanism, including an inlet pipe and a preheating component, the preheating component including a turbine adapter, a temperature sensor, and a preheating tube connected sequentially to the inlet pipe, the preheating tube being provided with a heating resistor for heating the pure water inside the preheating tube, and the preheating component outputting pure water at a preset temperature and pressure; a water outlet mechanism, including an outlet pipe for outputting heated pure water; a heating mechanism, including a plurality of heating components for heating the pure water from the preheating component, all of the heating components being connected in series between the inlet pipe and the outlet pipe via pipelines; and an industrial control computer, the industrial control computer being electrically connected to the temperature sensor, the pressure sensor, the heating resistor, and the heating components, the industrial control computer being used to start or stop the heating resistor or the heating components to regulate the pure water temperature.

[0006] Preferably, the water inlet mechanism further includes a pneumatic valve for controlling the flow rate of the water inlet mechanism. The pneumatic valve is connected to the preheating pipe. A pressure sensor for measuring the water pressure inside the preheating pipe is provided on the side of the preheating pipe. The pneumatic valve is pneumatically connected to an external pneumatic power source. The industrial control computer starts and stops the pneumatic valve through an electrical connection with the external pneumatic power source. The industrial control computer is electrically connected to the pressure sensor. When the water pressure detected by the pressure sensor meets the preset parameters, the industrial control computer starts the pneumatic valve to output pure water.

[0007] Preferably, the preheating tube is provided with a first mounting hole, the heating resistor is sealed in the first mounting hole, and the bottom end of the heating resistor extends into the preheating tube.

[0008] Preferably, the preheating tube is provided with a second mounting hole, the pressure sensor is sealed in the second mounting hole, and an elastic sealing ring is provided between the pressure sensor and the second mounting hole.

[0009] Preferably, a variable diameter connecting block is provided between the pneumatic valve and the preheating pipe. The input port of the variable diameter connecting block is provided with a first pipe communicating with the preheating pipe, and the output port of the variable diameter connecting block is provided with a second pipe communicating with the pneumatic valve. The diameter of the first pipe is larger than the diameter of the second pipe.

[0010] Preferably, the inlet pipe is equipped with a first double-joint ball valve, and the outlet pipe is equipped with a second double-joint ball valve.

[0011] Preferably, it also includes a frame, wherein a plurality of crossbeams are arranged at the bottom of the frame, and a first support frame supporting the bottom of the water inlet mechanism is provided on the crossbeams.

[0012] Preferably, the crossbeam is provided with a pair of support columns, and the side of the support column facing the heating component is provided with a second support frame, which supports the bottom of the heating component.

[0013] Preferably, the frame is provided with a heat insulation cover, which is located on one side of the heating component.

[0014] Preferably, it also includes an electrical box door panel, wherein the side of the electrical box door panel facing the heating component is provided with a plurality of cooling fans, and the electrical box door panel is provided with louvers at the corresponding installation positions of the cooling fans.

[0015] In the technical solution provided by this utility model, during the process of pure water being input into the heating mechanism through the inlet pipe, the pure water first has its real-time temperature measured by a temperature sensor, and then enters the preheating tube. The industrial control computer, based on the temperature feedback from the temperature sensor, causes the non-metallic heating resistor to operate for a corresponding time to heat the pure water in the preheating tube. A pressure sensor detects the pure water pressure during the heating process to ensure that the pure water temperature and pressure are consistent before entering the heating mechanism. Then, the pure water sequentially enters the series-connected heating components for further heating, and the heated pure water is output through the outlet pipe. This design ensures the consistency of the pure water temperature before it enters the heating components, improving the stability and service life of the equipment. Attached Figure Description

[0027] Please refer to Figures 1 to 6 This utility model provides a pure water heating device, including a water inlet mechanism 1, comprising an inlet pipe 11 and a preheating component 12. The preheating component 12 includes a turbine adapter 121, a temperature sensor 122, and a preheating tube 123 connected sequentially to the inlet pipe 11. The preheating tube 123 is equipped with a heating resistor 1231 for heating the pure water inside the preheating tube 123. A pressure sensor 1232 for measuring the water pressure inside the preheating tube 123 is provided on the side of the preheating tube 123. The preheating component 12 outputs pure water at a preset temperature and pressure. The water outlet mechanism 2 includes an outlet pipe 21 that outputs heated pure water; the heating mechanism 3 includes several heating components 31 for heating pure water from the preheating component 12, all of which are connected in series between the inlet pipe 11 and the outlet pipe 21 via pipelines; and an industrial control computer that is electrically connected to the temperature sensor 122, the pressure sensor 1232, the heating resistor 1231, and the heating components 31, respectively. The industrial control computer is used to start or stop the heating resistor 1231 or the heating components 31 to regulate the pure water temperature.

[0028] In the technical solution provided by this utility model, during the process of pure water being input into the heating mechanism 3 from the inlet pipe 11, the pure water first has its real-time temperature measured by the temperature sensor 122, and then enters the preheating pipe 123. The industrial control computer, based on the temperature feedback from the temperature sensor 122, causes the non-metallic heating resistor 1231 to operate for a corresponding time to heat the pure water in the preheating pipe 123. The pressure sensor 1232 detects the pure water pressure during the heating process to ensure that the pure water temperature and pressure are consistent before entering the heating mechanism 3. Then, the pure water sequentially enters the series-connected heating components 31 for heating, and the heated pure water is output through the outlet pipe 21. This design ensures the consistency of the pure water temperature before entering the heating components 31, improving the stability and service life of the equipment.

[0029] Please refer to Figures 1 to 6 In this embodiment, the water inlet mechanism 1 also includes a pneumatic valve 13 for controlling the flow rate of the water inlet mechanism 1. The pneumatic valve 13 is connected to the preheating pipe 123 and is pneumatically connected to an external pneumatic power source. The industrial control computer controls the pneumatic valve 13 through an electrical connection with the external pneumatic power source. By controlling the opening degree of the pneumatic valve 13, the flow rate of pure water entering the preheating pipe 123 and the heating mechanism 3 is adjusted, making the heating process more efficient. When rapid heating is required, the flow rate is increased; when stable temperature is required, the flow rate is decreased, achieving a dual improvement in heating efficiency and temperature stability.

[0030] Please refer to Figures 1 to 6In this embodiment, the preheating tube 123 has a first mounting hole 1233, and the heating resistor 1231 is sealed inside the first mounting hole 1233, with its bottom end extending into the preheating tube 123. The preheating tube 123 has a second mounting hole 1234, and the pressure sensor 1232 is sealed inside the second mounting hole 1234, with an elastic sealing ring between the pressure sensor 1232 and the second mounting hole 1234. This design not only improves the accuracy of pressure measurement and ensures the stability of pressure data, but also effectively prevents safety hazards caused by water pressure fluctuations or leaks.

[0031] Please refer to Figures 1 to 6 In this embodiment, a reducing diameter connecting block 14 is provided between the pneumatic valve 13 and the preheating pipe 123. The input port of the reducing diameter connecting block 14 is provided with a first pipe 141 communicating with the preheating pipe 123, and the output port of the reducing diameter connecting block 14 is provided with a second pipe 142 communicating with the pneumatic valve 13. The diameter of the first pipe 141 is larger than the diameter of the second pipe 142. The design of the reducing diameter connecting block 14 slows down the flow rate of water when it passes through, thereby facilitating more precise flow control by the pneumatic valve 13. Since the first pipe 141 has a larger diameter, it can accommodate more water flow, while the second pipe 142 has a smaller diameter, which limits the water flow velocity. Due to the pipe diameter change, the water flow will experience pressure changes when passing through the reducing diameter connecting block 14. This change helps to buffer the pressure of the water flow and reduce equipment damage or performance degradation caused by water flow impact.

[0032] Please refer to Figures 1 to 6 In this embodiment, the inlet pipe 11 is equipped with a first double-joint ball valve 111, and the outlet pipe 21 is equipped with a second double-joint ball valve 22. The double-joint ball valves not only have on / off functions but can also regulate flow rate to a certain extent. By adjusting the valve opening, precise control of the pure water flow rate entering and exiting the pure water heating device can be achieved, thereby meeting different heating requirements.

[0033] Please refer to Figures 1 to 6 In this embodiment, the pure water heating device also includes a frame 4. Several crossbeams 41 are arranged at the bottom of the frame 4. A first support frame 411, supporting the bottom of the water inlet mechanism 1, is provided on each crossbeam 41. A pair of support columns 413 are provided on each crossbeam 41. A second support frame 412 is provided on the side of the support column 413 facing the heating component 31, supporting the bottom of the heating component 31. The frame 4 is provided with a heat insulation cover 42, located on one side of the heating component 31. Since multiple heating components 31 are connected in series vertically, additional support components are needed for reinforcement. The frame 4, crossbeams 41, first support frame 411, and second support frame 412 together constitute a stable support system, effectively preventing damage caused by vibration or external impact of the water inlet mechanism 1 and the heating component 31.

[0034] Please refer to Figures 1 to 6 In this embodiment, the pure water heating device also includes an electrical box door panel 43. Several cooling fans 431 are provided on the side of the electrical box door panel 43 facing the heating component 31. Louvers 432 are provided at the corresponding mounting locations of the cooling fans 431 on the electrical box door panel 43. The operation of the cooling fans 431 accelerates the airflow inside the electrical box, promptly dissipating the heat generated by the heating component 31 and other electrical components, preventing equipment malfunction or performance degradation due to excessive temperature. Simultaneously, the design of the louvers 432 not only provides an air intake channel for the cooling fans 431 but also prevents dust, insects, and other debris from entering the electrical box, keeping the interior of the electrical box clean and dry.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
