Technical Field

[0001] The utility model belongs to the technical field of biological reagent heating devices, and more specifically relates to a liquid-through-type preheating device. Background Art

[0002] Liquid preheating refers to preheating the liquid to a specified temperature before use.

[0003] In fields such as molecular hybridization, certain reagents need to be heated to a specific temperature in advance, and then react with other reagents or samples to complete the entire hybridization process. It is not possible to react and heat at the same time; nor can two reagents be mixed together and heated at the same time. The current liquid preheating methods include two schemes, and the following technical problems exist: Scheme 1: Heat the liquid directly in the container, and then pump it into the reaction chamber; Problem: This will cause the excess liquid in the container to heat up and cool down repeatedly, losing its original properties; and it is easy to cause reagent contamination. Or the excess reagents are washed away each time, which is very wasteful. Scheme 2: Use a heating tube for direct heating, and heat while flowing to the chamber; Problem: The heat dissipation is fast, and the temperature is not easy to control;

[0004] It can be seen that how to provide a device that can instantly heat and maintain a constant temperature is a technical problem that those skilled in the art urgently need to solve. Utility Model Content

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0041] Example:

[0042] like Figure 1-5 As shown, the first embodiment of the present invention proposes a liquid-through preheating device, which includes: a tank body 1, a heating component and a temperature sensor 8;

[0043] In which, the tank body 1 has a accommodating space and a heating pipe arranged in the accommodating space, the tube wall material of the heating pipe is made of heat-conductive material, and the heating pipe has a liquid inlet 9 and a liquid outlet 10, which respectively extend out of the tank body 1; wherein, the accommodating space is used to accommodate heating liquid, and the heating pipe is used to accommodate preheating reagent to be heated by the heating liquid; the heating component is arranged in the accommodating space of the tank body 1 to heat the heating liquid in the accommodating space; the sensing end of the temperature sensor 8 is arranged in the accommodating cavity of the tank body 1 to perform thermal sensing of the heating liquid in the tank body 1.

[0044] Specifically, the liquid-through preheating device of this embodiment accommodates a heating liquid, such as silicone oil, in the storage space of the tank body 1, which accounts for approximately 80% of the volume of the tank body 1. The heating component then heats the heating liquid to a preset temperature, transferring the temperature of the heating liquid to the heating pipe. This heats the preheating reagent in the heating pipe, which then maintains a constant temperature. This continuously heats and insulates the preheating liquid, solving the technical problems of existing pyrolysis devices, which heat slowly and cannot maintain a constant temperature. Furthermore, a temperature sensor 8 is provided within the tank body 1 to monitor the temperature within the tank body 1 in real time, preventing changes in the performance of the preheating reagent due to overheating or insufficient heating, which could affect the test accuracy.

[0045] In some preferred embodiments, the heating pipe is a spiral tubular winding formed into a stacked shape. The heating pipe is connected through a pair of branch pipes and extends out of the outside of the tank body 1 to form the liquid inlet 9 and the liquid outlet 10. The liquid inlet 9 is used to add the preheating reagent, and the liquid outlet 10 is used to extract the heated preheating reagent.

[0046] In some preferred embodiments, the preheating device further includes a pressure warning component, which includes a sensing end and a warning end. The sensing end of the pressure warning component is arranged inside the tank body 1, and the warning end is arranged outside the tank body 1. Specifically, the pressure warning component includes an airbag 4, the inlet of the airbag 4 is the sensing end and is connected to the interior of the tank body 1, and the airbag 4 body is the warning end.

[0047] In the above embodiment, the core of the preheating device is a spiral heating pipe. This design not only improves heat exchange efficiency but also saves space. The pipe is made of special materials and can withstand long-term high-temperature operation without deformation or damage.

[0048] The spiral heating pipes are stacked within the tank 1. The carefully designed pipe layout ensures uniform heating of the preheating reagent as it passes through the pipes. The pipes connect to the exterior of the tank 1 at either end, forming an inlet 9 and an outlet 10. The inlet 9 facilitates the addition of the preheating reagent, while the outlet 10 allows for the removal of the heated reagent after the heating process is complete, ensuring ease of operation and process continuity.

[0049] To further enhance the safety and reliability of the preheating device, we've introduced a pressure warning component. This component consists of two parts: a sensing terminal and a warning terminal. The sensing terminal, located inside the tank 1 and directly connected to the inlet of the airbag 4, monitors pressure changes within the tank in real time. When the pressure reaches a preset safety threshold, the sensing terminal triggers the warning terminal's response mechanism.

[0050] The warning terminal, located on the exterior of the tank 1, alerts operators to changes in internal tank pressure through visual or audible signals, allowing them to take appropriate safety measures. The airbag 4, part of the pressure warning assembly, has its inlet connected to the sensing terminal, while the airbag 4 itself serves as the warning terminal. The design of the airbag 4 allows it to expand or contract in response to pressure changes. This physical change intuitively reflects the internal tank pressure state, enhancing the intuitiveness and responsiveness of the warning system.

[0051] The preheating device also includes a series of auxiliary components, such as a temperature control system, flow control valves, and an automatic control system. These components work together to ensure precise control and efficient operation of the preheating process. The temperature control system monitors and adjusts the temperature within the heating pipe in real time, ensuring that the preheating reagent is heated at the optimal temperature. The flow control valve allows the operator to adjust the flow rate as needed to accommodate different heating requirements. The automatic control system automatically performs operations such as heating, cooling, and pressure monitoring through pre-set programs, reducing manual intervention and improving the level of automation.

[0052] In summary, the preheating device of this patent embodiment provides an efficient, safe and easy-to-operate preheating solution through its unique spiral heating pipe design, pressure warning component and a series of auxiliary control systems. It is suitable for a variety of industrial heating processes and has broad application prospects and market potential.

[0053] In some preferred embodiments, the tank body 1 has an opening, which is covered by an upper cover 2 to form a closed tank body 1. The upper cover 2 is provided with a plurality of connecting holes for passing and restricting a pair of branch pipes, the temperature sensor 8 and the airbag 4.

[0054] In some preferred embodiments, the preheating device further includes a first pressure plate 3, which is arranged on the outer wall of the upper cover 2. The first pressure plate 3 is provided with a plurality of pressure holes, and the plurality of pressure holes are used to correspondingly penetrate a pair of the branch pipes and the temperature sensor 8.

[0055] In the above embodiment, the tank body 1 is designed with an opening, which is sealed by an upper cover 2 to form a closed tank body 1 environment. The upper cover 2 is specially designed with a number of connection holes, which are provided to penetrate and restrict a pair of the branch pipes, the temperature sensor 8 and the airbag 4 to ensure that each component can be accurately installed and perform its function. In addition, in order to further enhance the sealing and safety of the tank body 1, the preheating device also includes a first pressure plate 3, which is provided on the outer wall of the upper cover 2. The first pressure plate 3 is also provided with a number of pressure holes, which correspond to the pair of branch pipes and the temperature sensor 8 to ensure the fixation and operational stability of these components inside the tank body 1. Through such a design, not only the effective heating of the preheating reagent is achieved, but also the safety and reliability of the entire preheating process are guaranteed through precise temperature and pressure control.

[0056] In some preferred embodiments, the preheating device further includes a second pressing plate 6 , which is disposed between the tank body 1 and the heating film 5 and is used to press the heating film 5 to prevent the heating film 5 from falling off.

[0057] In some preferred embodiments, the upper cover 2 is further provided with a plurality of thermal insulation pads 7 for thermal insulation.

[0058] In some preferred embodiments, the heating assembly includes a heating film 5 , which is provided at the bottom of the tank body 1 and is used to heat the tank body 1 .

[0059] In some preferred embodiments, the preheating device further includes a plurality of sealing gaskets, which are respectively provided at the portion where the pair of branch pipes pass through the tank body 1 and the portion where the airbag 4 passes through the tank body 1. The sealing gaskets include a liquid outlet sealing gasket 11, a liquid inlet 9 sealing gasket, an airbag sealing gasket 12, and an upper cover sealing gasket 13, which are provided at corresponding positions to enhance the sealing performance of the tank body 1.

[0060] It is easy for those skilled in the art to understand that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
