Description

Technical Field

[0001] The utility model relates to the technical field of quartz heaters, and particularly relates to a quartz heater for chemical liquids. Background Technique

[0002] In many chemical experiments, industrial production processes, and specific chemical treatment links, it is often necessary to heat chemical liquids. Precise and stable heating helps to promote chemical reactions, change the physical properties of liquids (such as reducing viscosity for easier transportation or mixing), accelerate certain chemical process, etc. Quartz has excellent high-temperature resistance characteristics and can withstand high temperatures without softening, deforming, or decomposing. In the heating of chemical liquids, it can adapt to various heating temperature requirements. Whether it is the conventional heating reaction temperature or relatively high temperature conditions, it can work stably for a long time in a high-temperature environment, ensuring the continuity and reliability of the heating process. However, some existing quartz heaters do not fully consider the uniformity of heat distribution in their structural design. For example, the layout of heating elements is unreasonable, which may lead to uneven heat conduction inside the quartz heater, resulting in a large difference in the heat received by chemical liquids in different regions. In addition, some quartz heaters are designed with complex internal structures, such as multi-layer nesting, curved channels, etc. These complex structures make it difficult for cleaning tools to reach all areas, easily leaving cleaning dead ends, resulting in the gradual accumulation of residues, affecting the performance and service life of the heater. Content of the Utility Model

[0029] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0030] A quartz heater for chemical liquids includes a chemical liquid storage tank 1. An upper external thread groove 2 is formed in the upper part of the outer surface of the chemical liquid storage tank 1. An upper internal thread groove 3 is formed in the upper part of the inner wall of the chemical liquid storage tank 1. A silane coating 4 is applied to the lower part of the inner wall of the chemical liquid storage tank 1. A liquid inlet pipe 5 is fixedly connected to the right part of the surface of the chemical liquid storage tank 1. A liquid outlet pipe 6 is fixedly connected to the right part of the surface of the chemical liquid storage tank 1, and the liquid outlet pipe 6 is located directly below the liquid inlet pipe 5. A quartz heater structure 7 is arranged directly above the chemical liquid storage tank 1, and the lower part of the quartz heater structure 7 is located inside the chemical liquid storage tank 1.

[0031] In this embodiment, the structure of the quartz heater 7 includes an upper cover shell 71. An inner heating base 72 is fixedly connected to the inner upper wall of the upper cover shell 71. A threaded inner groove hole 73 is formed between the upper cover shell 71 and the inner heating base 72. Three quartz inner liner heating tubes 74 are fixedly connected to the lower end of the inner heating base 72. Electric heating wires 75 are fixedly connected to the outer surfaces of the three quartz inner liner heating tubes 74. Three threaded groove holes 76 are formed in the lower end of the inner heating base 72. The three quartz inner liner heating tubes 74 are respectively located between the three threaded groove holes 76. Removable protective layer assemblies 77 are threadedly and movably connected in the three threaded groove holes 76. The three groups of removable protective layer assemblies 77 are distributed in an annular array. The chemical liquid storage tank 1 is threadedly and movably connected to the upper cover shell 71 through an upper external thread groove 2, and the upper part of the chemical liquid storage tank 1 is located in the threaded inner groove hole 73. The diameter area of the inner heating base 72 is equal to the inner diameter area of the chemical liquid storage tank 1. The inner heating base 72 is threadedly and movably connected to the chemical liquid storage tank 1 through an upper internal thread groove 3, and the lower part of the inner heating base 72 is located in the chemical liquid storage tank 1. The three quartz inner liner heating tubes 74 are distributed in an annular array, and the three quartz inner liner heating tubes 74 are jointly located in the chemical liquid storage tank 1.

[0032] Through the above scheme: The three quartz inner liner heating tubes 74 are distributed in an annular array. This layout method can enable the chemical liquids in all directions in the chemical liquid storage tank 1 to receive heat more evenly. The three heating tubes are jointly located in the chemical liquid storage tank 1 and can heat from different angles, avoiding uneven heat caused by single-position heating. The diameter area of the inner heating base 72 is equal to the inner diameter area of the chemical liquid storage tank 1, and the lower part of the inner heating base 72 is located in the chemical liquid storage tank 1. This tight connection enables heat to be transferred more directly from the inner heating base 72 to the chemical liquid, reducing heat loss. At the same time, electric heating wires 75 are fixedly connected to the outer surfaces of the three quartz inner liner heating tubes 74, ensuring the stability and uniformity of the heating source.

[0033] In this embodiment, the removable protective layer assembly 77 includes a quartz outer tube 771. A threaded hole groove 773 is formed in the upper part of the outer surface of the quartz outer tube 771. A polytetrafluoroethylene coating 772 is coated on the lower part of the outer surface of the quartz outer tube 771, and the polytetrafluoroethylene coating 772 is located directly below the threaded hole groove 773. The quartz outer tube 771 is detachably connected to the inner heating base 72 through the threaded hole groove 773 and the threaded groove hole 76. The quartz inner liner heating tube 74 is located inside the quartz outer tube 771. The electric heating wire 75 is in close contact with the inner wall of the quartz outer tube 771 but not fixed. The sum of the length of the quartz outer tube 771 and the height of the inner heating base 72 is equal to the inner wall length of the chemical liquid storage tank 1.

[0034] Through the above solution: The quartz outer tube 771 is detachably connected to the inner heating base 72 through the threaded hole groove 773 and the threaded groove hole 76. When cleaning is required, the quartz outer tube 771 can be easily detached to thoroughly clean the quartz inner liner heating tube 74 and the electric heating wire 75 inside it, avoiding the problem of difficult cleaning of complex structures. The lower part of the outer surface of the quartz outer tube 771 is coated with a polytetrafluoroethylene coating 772. This coating has non-stick properties, can effectively reduce the adhesion of chemical liquid residues, and reduce the cleaning difficulty. Even if there are a small amount of residues, they are easier to clean, avoiding the accumulation of residues from affecting the performance and service life of the heater.

[0035] It should be noted that the present utility model is a quartz heater for chemical liquids. During use, first, the chemical liquid storage tank 1 is threadedly and movably connected to the upper cover shell 71 of the quartz heater structure 7 through the outer upper threaded groove 2, so that the upper part of the chemical liquid storage tank 1 is located in the threaded inner groove hole 73 formed between the upper cover shell 71 and the inner heating base 72 to achieve a stable connection. The diameter area of the inner heating base 72 is equal to the inner diameter area of the chemical liquid storage tank 1, and is further threadedly and movably connected to the chemical liquid storage tank 1 through the inner upper threaded groove 3 to ensure that the lower part of the inner heating base 72 is located inside the chemical liquid storage tank 1, preparing for heating the chemical liquid. When heating the chemical liquid is required, the electric heating wire 75 fixedly connected to the outer surface of the three quartz inner liner heating tubes 74 is energized. The electric heating wire 75 generates heat. Since the electric heating wire 75 is in close contact with but not fixed to the inner wall of the quartz outer tube 771, the heat can be quickly transferred to the quartz outer tube 771. The heat inside the quartz outer tube 771 is further transferred to the three quartz inner liner heating tubes 74 distributed in an annular array. Because the quartz inner liner heating tubes 74 are all located inside the chemical liquid storage tank 1, the chemical liquid in the storage tank can be heated. The design of the annular array distribution enables the chemical liquid to receive heat more evenly, improving the heating efficiency and uniformity. In addition, the quartz outer tube 771 is detachably connected to the inner heating base 72 through the threaded hole groove 773 on the upper part of the outer surface and the threaded groove hole 76 at the lower end of the inner heating base 72. This design facilitates the detachment of the quartz outer tube 771 when maintenance or cleaning is required. The lower part of the outer surface of the quartz outer tube 771 is coated with a polytetrafluoroethylene coating 772. This coating has non-stick and corrosion-resistant properties. On the one hand, it can prevent chemical liquids from adhering to the quartz outer tube 771, and on the other hand, it is also convenient to remove the possible residual chemical substances during cleaning. The chemical liquid enters the chemical liquid storage tank 1 through the liquid inlet pipe 5 and can flow out through the liquid outlet pipe 6 after being heated in the tank, realizing the heating and conveying process of the chemical liquid. The lower part of the inner wall of the chemical liquid storage tank 1 is coated with a silane coating 4. This coating can play a role in protecting the inner wall of the storage tank, preventing the chemical liquid from corroding the storage tank, and also helping to reduce the residue of the chemical liquid on the inner wall of the tank, facilitating cleaning and maintenance.
