Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a heat preservation structure of an electric heater. Background Art

[0002] Plunger pumps are commonly used to transport liquids or gases. Temperature fluctuations during the flow of liquids and gases through the pump can directly affect the state and properties of the materials. When the temperature drops, some substances tend to condense and solidify, potentially causing ice accumulation in pipelines and impacting production and transportation. Furthermore, temperature fluctuations can cause changes in some chemical processes, thereby affecting the composition and properties of the product. Therefore, insulating the plunger pump can maintain the appropriate temperature of the materials, ensuring the quality and properties of the fluid, and improving production results.

[0003] In the past, plunger pumps were heated primarily by electric heaters. These consisted of sealed, half-shells with built-in heating rods. When joined together, they formed a box, which heated the plunger pump. However, during the heating process, a large amount of heat energy was transferred outward through the shell, reducing the efficiency of the plunger pump. Furthermore, the electric heater needed to be kept running continuously, wasting energy. Therefore, the present invention proposes an electric heater insulation structure to address these issues.

[0011] The mounting plate is arranged around the outer side of the electric heater, and a distance is left between the mounting plate and the electric heater;

[0012] The reflective cylinders close to the electric heater are arranged in an array on the inner side surface of the mounting plate, and adjacent reflective cylinders are in contact with each other;

[0028] like Figure 1-2 As shown, the utility model provides an electric heater insulation structure, which includes:

[0029] An electric heater 1, used for heating the plunger pump;

[0030] a first heat-insulating component, which is arranged around the outer side of the electric heater 1 and is used to reflect and store heat energy transferred from the electric heater 1;

[0031] The first heat preservation assembly includes: a mounting plate 2 and a reflective tube 3;

[0032] The mounting plate 2 is arranged around the outer side of the electric heater, and a distance is left between the mounting plate 2 and the electric heater 1;

[0033] The reflective cylinders 3 close to the electric heater 1 are arranged in an array on the inner side surface of the mounting plate 2, and adjacent reflective cylinders 3 are in contact with each other;

[0034] The second heat-insulating assembly is arranged around the outer side of the mounting plate 2 .

[0035] The cross section of the reflective tube 3 is a regular hexagonal shape, and a heat storage layer is provided on the inner wall of the reflective tube 3 .

[0036] The heat storage layer is a solid material in the sensible heat storage material, wherein the heat storage layer can be a solid material such as aluminum-based alloy heat storage material, magnesium oxide, magnesium iron oxide and industrial salt.

[0037] A plurality of grooves are provided on the inner wall of the reflective tube 3 , and the grooves are arranged in a honeycomb shape.

[0038] Among them, the function of the first insulation component is that when the electric heater is in the heating process, the heat energy will be transferred outward along the electric heater shell. When the heat energy contacts the first insulation component, due to the arrangement of the array-type reflective tube, the thermal conductivity of the air is much smaller than that of the solid material. Therefore, the use of a porous structure can significantly reduce the apparent thermal conductivity of the electric heater material, hindering the progress of heat conduction. From the perspective of convective heat transfer, the porous material blocks the large-space flow of air, making it a tiny space with a very limited scale, making it difficult for the natural convective heat transfer of the air to proceed, effectively hindering the progress of convective heat transfer. From the perspective of radiation heat transfer, the array-type porous material is equivalent to using a multi-layer heat shield, which can multiply hinder the progress of radiation heat transfer, and the heat storage material is arranged in the reflective tube, which can store heat energy in the first insulation component, thereby having a high-temperature effect on the electric heater, thereby improving the heating efficiency of the plunger pump.

[0039] a second heat-insulating component, which is arranged around the first heat-insulating component and is used to reduce the heat energy passing through the first heat-insulating component to exchange heat with the outside world;

[0040] The connection terminal of the electric heater 1 is set through the first insulation component and the second insulation component, and is used to connect to the power supply to heat the plunger pump.

[0041] The second heat-insulating assembly comprises: a first heat-insulating layer 4 and a second heat-insulating layer 5;

[0042] The first heat insulation layer 4 is tightly arranged around the outer side of the mounting plate 2;

[0043] The second heat-insulating layer 5 is tightly arranged around the outer side of the first heat-insulating layer 4;

[0044] The outer layer of the second heat insulation layer 5 is provided with a protective plate 6 .

[0045] The first heat insulation layer 4 is a glass wool layer, and the second heat insulation layer 5 is a ceramic plate layer.

[0046] Among them, the function of the second insulation component is to block the heat energy transferred from the first insulation component again on the basis of the first insulation component, and seal the heat energy inside the insulation structure as much as possible. Since both glass wool and ceramic plates have excellent heat resistance, when a small amount of heat energy passes through the first insulation component, it will also be blocked by two layers of flame retardant materials, thereby reducing the heat transfer effect between the heat energy and the outside world.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.

Such improvements and variations shall also be considered within the scope of protection of the present invention.
