Description

Technical Field

[0001] This utility model relates to the technical field of high-temperature baths, and in particular to a temperature control system for a high-temperature bath. Background Technology

[0002] Currently, the sealing process for aluminum alloys after anodizing and dyeing is generally a common sealing process. Its advantages are low cost and high sealing efficiency, but its disadvantage is that it usually uses nickel-containing compounds (such as nickel fluoride, nickel acetate, etc.) as the core component of the sealing agent, which can easily cause heavy metal pollution risks to the environment.

[0003] In recent years, nickel-free sealing processes have emerged in the market for medical devices, food contact materials, infant products, and export products (such as high-end mobile phones) that have strict standards for nickel release in the EU and other countries. These processes use nickel-free sealing agents (such as zirconium salts, titanium salts, silanes, etc.), which reduces the risk of heavy metal pollution to the environment and lowers the possibility of causing allergies to people who come into contact with the material.

[0004] However, the nickel-free sealing process has strict requirements for the stability and uniformity of the temperature inside the tank, especially requiring automated equipment with a large production capacity. Because the tank size is large, it is more difficult to maintain the temperature uniformity. If the stability and uniformity of the temperature inside the tank do not meet the process requirements, the yield will be greatly reduced. Utility Model Content

[0005] One objective of this invention is to provide a temperature control system for a high-temperature tank, ensuring that the temperature stability and uniformity within the high-temperature sealing tank meet process requirements.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A temperature control system for a high-temperature tank includes a main tank section and a secondary tank section, wherein the secondary tank section is located inside the main tank section, and a filter is connected between the main tank section and the secondary tank section.

[0008] The main tank section is equipped with a first steam coil and a second steam coil. Long-side overflow pockets are installed on both sides of the main tank section. A tank bottom equalization plate is fixed to the bottom of the inner side of the main tank section. Baffles are installed at both ends of the main tank section along the vertical direction. A tank cover is hinged to the upper end of the main tank section.

[0009] The secondary tank section is equipped with a third steam coil, a fourth steam coil, and a fifth steam coil.

[0010] As a preferred technical solution, a circulation pump is installed at the lower outer end of the main tank section, and an overflow outlet is provided at the middle outer side of the main tank section, which is connected to the long side overflow pocket.

[0011] As a preferred technical solution, a side mounting plate is installed at the upper end of the main groove, a seated bearing is connected to the side mounting plate, a rotating shaft is rotatably connected to the seated bearing, and several groove support seats are distributed on the rotating shaft.

[0012] As a preferred technical solution, a cylinder lifting bracket is fixed to the outer side of the main groove portion, a cylinder mounting seat is fixed to the cylinder lifting bracket, a first cylinder is mounted on the cylinder mounting seat, and a connecting rod is connected between the drive end of the first cylinder and the end of the rotating shaft.

[0013] As a preferred technical solution, both the interior of the main tank and the interior of the secondary tank are equipped with circulation pipes, with the openings of the circulation pipes facing upwards.

[0014] As a preferred technical solution, a tank-side exhaust hood is provided on the outer side of the main tank section.

[0015] As a preferred technical solution, a circulation inlet is installed on the outer side of the main tank section, and a self-circulating flange, a circulation outlet, a main tank overflow return port, a safety overflow drain port, and a water inlet are installed on the secondary tank section.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 8 As shown in this embodiment, a temperature control system for a high-temperature tank includes a main tank section and a secondary tank section. The secondary tank section is located inside the main tank section, and a filter is connected between the main tank section and the secondary tank section.

[0030] Multiple measures are taken to ensure that the temperature stability and uniformity inside the high-temperature (>96℃) sealing tank meets the process requirements (e.g., the temperature difference of 24 points inside a 4500L tank is ≤±0.5℃).

[0031] The main tank is equipped with a first steam coil 1 and a second steam coil 2. Long-side overflow pockets 3 are installed on both sides of the main tank. A bottom equalization plate 4 is fixed to the inner bottom of the main tank. Baffles 5 are installed vertically at both ends of the main tank. A tank cover 6 is hinged to the upper end of the main tank. These features reduce heat dissipation from the high-temperature main tank and save energy. The long-side overflow pockets 3 allow the tank liquid to overflow along both sides of the entire tank length, ensuring uniform exchange of the tank liquid along the tank length, thereby improving the uniformity of the tank liquid temperature. The bottom equalization plate 4 prevents the new tank liquid drawn from the secondary tank from directly impacting the product, instead distributing it evenly along the entire bottom of the tank and allowing it to slowly overflow. This improves the uniformity of the tank liquid temperature. The vertical baffle 5 separates the part of the steam coil from the effective working part of the tank, preventing the tank liquid heated by the steam coil from flowing and exchanging with the tank liquid in the effective working part, thereby improving the uniformity of the tank liquid temperature. The automatic tank cover 6 blocks the flow and exchange of air between the tank surface and the outside air, reducing heat loss from the liquid surface, thereby improving the uniformity of the tank liquid temperature. The auxiliary tank is equipped with a third steam coil 7, a fourth steam coil 8, and a fifth steam coil 9. Based on the difference between the actual temperature of the tank liquid and the set temperature, different steam coils are automatically activated for heating.

[0032] In terms of specific structure, a circulation pump 10 is installed at the lower outer side of the main tank section, and an overflow outlet 11 is provided at the middle outer side of the main tank section, which is connected to the long side overflow hopper 3; a side mounting plate 12 is installed at the upper end of the main tank section, and a seated bearing 13 is connected to the side mounting plate, with a rotating shaft 14 rotatably connected to the seated bearing 13, and several tank support seats 15 are distributed on the rotating shaft 14; a cylinder lifting bracket 16 is fixed to the outer side of the main tank section, and a cylinder mounting seat 17 is fixed to the cylinder lifting bracket 16, with a cylinder mounting seat 17 installed on the cylinder mounting seat 17. The first cylinder 18 has a connecting rod 19 connecting its drive end to the end of the rotating shaft 14; both the main tank and the secondary tank are equipped with circulation pipes 20, with the openings of the circulation pipes 20 facing upwards; the outer side of the main tank is provided with a tank-side air extraction hood 21; the outer side of the main tank is equipped with a circulation inlet 22; the secondary tank is equipped with a self-circulating flange 23, a circulation outlet 24, a main tank overflow return port 25, a safety overflow drain port 26, and a water inlet 27; both the main tank and the secondary tank are equipped with drain flanges 28.

[0033] The circulation system consists of a filtration circulation in the main tank and a self-circulation circulation in the secondary tank. In the main tank, the liquid is drawn from the secondary tank and sprayed upwards from both sides at the bottom. Fresh liquid slowly overflows through the flow equalization plate 4 at the bottom of the main tank, then overflows from the long side overflow pockets 3 on both sides, flowing back into the secondary tank through the overflow pipe to form a closed loop. This ensures thorough and uniform exchange of the liquid, thereby improving the uniformity of the liquid temperature. In the secondary tank, the self-circulation system draws liquid from the bottom of the secondary tank and then enters from the other side of the secondary tank to form a closed loop, ensuring that the liquid temperature in the secondary tank is as uniform as possible, thus improving the uniformity of the liquid temperature in the main tank.

[0034] The steam heating section includes steam coils, pneumatic valve assemblies, coolant assemblies, main and branch steam pipes, and their insulation. The entire temperature control system (including the main tank and auxiliary tank) has five independently controlled steam coils. The first steam coil 1 accounts for 70% of the heating power of the main tank, the second steam coil 2 accounts for 30%, the third steam coil 7 accounts for 70% of the total heating power of the main and auxiliary tanks, the fourth steam coil 8 accounts for 20% of the total heating power of the main and auxiliary tanks, and the fifth steam coil 9 accounts for 10% of the total heating power of the main and auxiliary tanks. The opening and closing of each pneumatic ball valve is controlled according to the difference between the actual temperature of the tank liquid and the set temperature, which can maximize the stability of the tank liquid temperature.

[0035] Work process:

[0036] 1. When the machine is first started, all five steam coils are heated with steam.

[0037] 2. When the temperature reaches 5°C from the set temperature (adjustable), turn off the steam in the first steam coil 1;

[0038] 3. When the temperature reaches 2°C from the set temperature (adjustable), turn off the steam from the second steam coil 2;

[0039] 4. When the temperature reaches 1°C from the set temperature (adjustable), turn off the steam from the third steam coil 7;

[0040] 5. When the bath liquid reaches the set temperature, turn off the steam from the fourth steam coil 8;

[0041] At this point, only the fifth steam coil 9 is still supplying steam. Since the heating power of the fifth steam coil 9 is very small, it is mainly used to maintain the heat dissipation of the tank and the heat carried away when the workpiece is lifted. Therefore, it can maximize the stability of the tank liquid temperature.

[0042] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
