Description

Technical Field

[0001] This application relates to the field of laboratory electric heating equipment technology, and in particular to a heating container insulation module for an electric heating plate. Background Technology

[0002] In laboratories of chemistry, biology, and medicine, electric hot plates (heating platforms) are commonly used heating devices for heating, maintaining temperature, or stirring samples in beakers, flasks, and other heating containers. Currently, most electric hot plates use a surface contact heating method, meaning heat is conducted from the hot plate to the heating container only through the bottom of the container.

[0003] The existing technology has the following main drawbacks: During the heating process, the bottom of the container receives heat, but its side walls and the space above are completely exposed to the air, causing a large amount of heat to be lost to the environment through convection and radiation. This not only wastes energy but also makes the heating rate slow, especially in experiments with high thermal efficiency requirements. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a heating container insulation module for electric heating plates, which can be adapted to heating containers of different sizes and quantities on electric heating plates to achieve efficient insulation.

[0005] To achieve the above objectives, this application adopts the following technical solution: This application provides a heating container insulation module for an electric heating plate, the heating container insulation module comprising: Two side insulation blocks, which are long strips extending in the front-to-back direction, are arranged in parallel left and right, and have guide grooves extending in the front-to-back direction on the opposite sides of the two side insulation blocks. At least two adjustable insulation blocks, each adjustable insulation block has guide blocks at its left and right ends corresponding to the guide groove, and the guide blocks of the adjustable insulation blocks are slidably engaged with the guide grooves of the side insulation blocks; The heating container insulation module is placed on the heating plate, and two side insulation blocks and two adjacent front and rear adjustable insulation blocks form an insulation area for accommodating the heating container.

[0006] As a preferred technical solution, the height of both the side insulation block and the adjustable insulation block is no higher than one-third of the height of the heating container.

[0007] As a preferred technical solution, the front and rear surfaces of the adjustable heat-insulating block are respectively curved surfaces adapted to the shape of the heating container.

[0008] As a preferred technical solution, the side insulation block is made of heat-insulating material, and the adjustable insulation block is made of a flexible material that is thermally conductive and resistant to high temperatures.

[0009] As a preferred technical solution, the side insulation block is made of rigid aluminum silicate fiberboard, aerogel felt, or microporous calcium silicate board; the adjustable insulation block is made of alkali-free glass fiber cloth covered with aluminum foil or silicone, or the adjustable insulation block is made of silicone pad reinforced with metal wire, or the adjustable insulation block is made of carbon fiber woven felt.

[0010] Compared with the prior art, the beneficial effects of this application are as follows: By utilizing the guide grooves and sliding engagement between the adjustable insulation block and the side insulation block, the distance between adjacent adjustable insulation blocks can be easily adjusted, thereby creating insulation zones of different sizes. This allows a single insulation module to adapt to various sizes of heating containers (such as beakers and flasks of different diameters) and to simultaneously create independent insulation spaces for multiple containers on the heating plate as needed, making it extremely versatile.

[0011] The insulation zone formed by the side insulation blocks and adjustable insulation blocks effectively confines the heat around the side wall of the heating container within a local space, significantly reducing heat loss into the air. This allows the heat to act more concentratedly on the heating container, thereby improving the heating efficiency and speed of the heating plate and achieving the goal of energy saving and consumption reduction.

[0012] The entire module adopts a modular, sliding mechanical structure, requiring no complex tools or electric drive, and the adjustment operation is intuitive and simple. The module can be used directly by placing it on the heating plate without damaging the original equipment. As an accessory, it greatly enhances the functionality and ease of use of traditional heating plates. Attached Figure Description

Heating container insulation module; 11. Side insulation block; 111. Guide groove; 12. Adjustable insulation block; 121. Guide block. Detailed Implementation

[0014] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, this application provides a heating container insulation module 1 for an electric heating plate. The heating container insulation module 1 includes: two side insulation blocks 11 and at least two adjustable insulation blocks 12.

[0016] The two side insulation blocks 11 are elongated strips extending in the front-to-back direction. The two side insulation blocks 11 are arranged in parallel left and right. The sides of the two side insulation blocks 11 that are arranged opposite each other are provided with guide grooves 111 extending in the front-to-back direction.

[0017] Each adjustable insulation block 12 has a guide block 121 at its left and right ends that corresponds to the guide groove 111. The guide block 121 of the adjustable insulation block 12 slides in conjunction with the guide groove 111 of the side insulation block 11.

[0018] Specifically, the cross-sections of the guide groove 111 and the guide block 121 are T-shaped, ensuring that the adjustable insulation block 12 will not accidentally detach from the side insulation block 11 during horizontal sliding adjustment, greatly improving the stability and safety of the entire module during use. Secondly, this tight mechanical connection makes the gap between the adjustable insulation block 12 and the side insulation block 11 smaller and more controllable. This effectively reduces heat leakage from the gap at the connection point, helping to maintain the uniformity and stability of the thermal field within the insulation area, thereby improving the overall insulation efficiency. In addition, the T-shaped structure has better resistance to torsion and bending. When the adjustable insulation block 12 is subjected to the heated container or other external forces (such as collisions when placing or removing the container), the T-shaped joint can more effectively disperse stress, preventing damage to the guide block 121 or guide groove 111 due to uneven force, thus extending the service life of the device.

[0019] The heating container insulation module 1 is placed on the heating plate, and two side insulation blocks 11 and two adjacent front and rear adjustable insulation blocks 12 form an insulation area for accommodating the heating container.

[0020] By sliding the guide groove 111 and guide block 121 between the adjustable insulation block 12 and the side insulation block 11, the distance between adjacent adjustable insulation blocks 12 can be easily adjusted, thereby forming insulation areas of different sizes. This allows one insulation module to be adapted to heating containers of various sizes (such as beakers and flasks of different diameters), and can simultaneously create independent insulation spaces for multiple containers on the heating plate as needed, making it extremely versatile.

[0021] The insulation area formed by the side insulation block 11 and the adjustable insulation block 12 effectively confines the heat around the side wall of the heating container within a local space, significantly reducing heat loss into the air. This allows the heat to act more concentratedly on the heating container, thereby improving the heating efficiency and speed of the electric heating plate and achieving the goal of energy saving and consumption reduction.

[0022] The entire module adopts a modular, sliding mechanical structure, requiring no complex tools or electric drive, and the adjustment operation is intuitive and simple. The module can be used directly by placing it on the heating plate without damaging the original equipment. As an accessory, it greatly enhances the functionality and ease of use of traditional heating plates.

[0023] Furthermore, the height of both the side insulation block 11 and the adjustable insulation block 12 is no higher than one-third of the height of the heating container.

[0024] First, the height of the insulation module is limited to less than one-third of the container's height, providing ample observation windows for researchers. Technicians can clearly and unobstructedly observe key reaction information such as the liquid's volume, color changes, boiling status, and whether sediment or residue forms on the walls. This is crucial for monitoring and ensuring safety during experiments. Second, the low-profile design allows for complete openness above the container, facilitating the following operations: adding reagents (solid or liquid) directly from the top; inserting measuring instruments (thermometers, pH probes, stir bar, or condenser tubes); sampling (using pipettes or spoons to collect samples); and stirring (convenient manual stirring or observation of mechanical stirrers). Furthermore, the area with the greatest heat loss is the lower part of the container and the side walls immediately above the heating plate. Placing the insulation module in this area effectively blocks this major heat loss. The open top of the container acts as a controllable "safety valve," preventing heat and vapor from accumulating in a completely enclosed space, thus preventing excessive pressure or violent boiling and enhancing equipment safety.

[0025] Furthermore, the front and rear surfaces of the adjustable insulation block 12 are respectively curved surfaces adapted to the shape of the heating container.

[0026] For example, such as Figure 2 As shown, when the heating container is a commonly used conical beaker in the laboratory, the front and rear surfaces of the adjustable insulation block 12 can be designed as inwardly concave inclined planes or highly curved arc surfaces. In this way, when the two adjustable insulation blocks 12 are pushed close, their inclined surfaces can precisely fit against the conical sidewall of the beaker, forming an approximately V-shaped enclosing space. Figure 3As shown, when the heating container is a round-bottom flask or a spherical flask, the front and rear surfaces of the adjustable insulating block 12 can be designed as concave arc surfaces with curvature matching the diameter of the flask's sphere. In this way, when multiple adjustable insulating blocks 12 are closed, their inner surfaces can collectively form an approximately spherical enclosure, tightly fitting the lower part of the flask's sphere. Figure 4 As shown, when the heating container is a standard laboratory round beaker (whose sidewalls are approximately cylindrical), the front and rear surfaces of the adjustable heat-insulating block 12 can be designed as concave vertical cylindrical surfaces with a radius of curvature matching the outer diameter of the beaker.

[0027] First, compared to simple planar blocks, the prefabricated curved shape minimizes the gap between the inner surface of the adjustable insulation block 12 and the outer wall of the heating container. A tighter fit means a larger and more uniform contact area between the heat-conducting inner layer material and the container wall, allowing for more efficient heat transfer to the insulation module while significantly reducing thermal resistance and heat loss caused by air gaps. This results in a more uniform thermal field within the insulation area and a significantly improved insulation effect. Second, it enhances the universal adaptability of the same insulation module. For example, a concave-sloping adjustable insulation block 12 designed for "250mL to 500mL beakers" can accommodate beakers of different capacities but with similar cone angles. By adjusting the sliding distance, it can fit tightly against the sidewalls of beakers of different diameters. Similarly, a curved adjustable insulation block 12 designed for "spherical flasks" can adapt to a series of flasks with similar spherical diameters. This allows a limited number of adjustable insulation blocks 12 to cover an entire "container family" without the need to create custom modules for each precisely sized container, achieving flexible "one-to-many" adaptation. Furthermore, the curved surface provides better adhesion, more firmly "holding" the heated containers and reducing the risk of them tipping over due to external impacts or platform movement. This is especially important for experiments involving flammable, toxic, or expensive samples.

[0028] Furthermore, the side insulation block 11 is made of thermal insulation material, and the adjustable insulation block 12 is made of a thermally conductive and high-temperature resistant flexible material. Side insulation block 11 (thermal insulation material): Its main function is to act as a "thermal barrier," preventing heat loss to the left and right sides of the equipment and confining the heat within the insulation area enclosed by the side insulation block 11 and the adjustable insulation block 12. Adjustable insulation block 12 (thermally conductive flexible material): Its main function is to act as a "thermal conductor." It can closely adhere to the container wall, efficiently absorb the heat emitted by the container, and conduct and radiate it throughout the insulation area. The thermal conductivity of the adjustable insulation block 12 allows it to transfer heat from higher-temperature areas (such as the lower part near the heat source) to lower-temperature areas (such as the upper middle part of the container), helping to balance the temperature gradient of the container sidewalls, thereby improving the heating uniformity of the sample inside the container and avoiding the uneven phenomenon of intense heating only at the bottom while the sidewalls dissipate heat too quickly. The adjustable insulation block 12 is made of flexible material, which allows it to better adapt to minor unevenness or shape deviations on the container surface, ensuring close contact with the container wall, minimizing air gaps, and reducing contact thermal resistance. This close fit further enhances the aforementioned heat conduction and heat circulation effects.

[0029] Furthermore, the side insulation block 11 is made of rigid aluminum silicate fiberboard, aerogel felt, or microporous calcium silicate board; the adjustable insulation block 12 is made of alkali-free glass fiber cloth covered with aluminum foil or silicone, or the adjustable insulation block 12 is made of silicone pad reinforced with metal wire, or the adjustable insulation block 12 is made of carbon fiber woven felt.

[0030] Rigid aluminosilicate fiberboard is one of the most commonly used thermal insulation materials in laboratory and industrial high-temperature equipment. It is heat-resistant (up to 1000℃ or higher depending on the grade), has low thermal conductivity, and is lightweight. Rigid aluminosilicate fiberboard can be used to fill the outer shell of modules, or pre-formed rigid aluminosilicate fiberboard can be used directly as the main body of the outer structure.

[0031] Aerogel felt is one of the solid materials with the lowest known thermal conductivity, and is hailed as the "ultimate insulation material." It boasts exceptional insulation performance and can be made even thinner, but at a relatively high cost. As a high-end option, it can be filled into module shells to achieve excellent insulation, making it particularly suitable for applications with strict requirements on equipment surface temperature.

[0032] Microporous calcium silicate board is a rigid thermal insulation material with good structural strength, high temperature resistance, and stable thermal insulation performance. It can be directly processed into the outer shell of modules, serving both structural support and thermal insulation functions.

[0033] Alkali-free fiberglass cloth coated with aluminum foil or silicone is the core material of laboratory heating mantles. Alkali-free fiberglass itself is high-temperature resistant, insulating, and flexible. Laminating a thin layer of aluminum foil onto its surface greatly improves thermal conductivity and abrasion resistance. Alternatively, it can be impregnated with silicone to form a high-temperature resistant, flexible sealing layer.

[0034] Metal wire reinforced silicone pads: Silicone itself has a certain degree of flexibility and heat resistance (typically -60℃ to 250℃). Embedded metal wire mesh can significantly improve the uniformity of thermal conductivity within the surface, making it act like a "flexible heat conductor." The metal wires can be prefabricated into pads with a certain curvature and embedded in the inner layer of the module.

[0035] Carbon fiber woven felt: Carbon fiber has good thermal conductivity, strong directionality, light weight, and flexible design. It has good thermal conductivity along the woven surface. Carbon fiber woven felt can be used as a high-performance lining material, especially suitable for scenarios requiring rapid and uniform heat conduction.
