Technical Field

[0001] This utility model relates to the field of aluminum alloy solution furnace technology, and in particular to a heat preservation and heating device for aluminum alloy solution furnace. Background Technology

[0002] The aluminum alloy solution heat treatment electric furnace (hereinafter referred to as the furnace) is a periodic operation resistance furnace, mainly used for heating aluminum alloy parts for solution treatment. It features uniform furnace temperature, rapid heating, short immersion time, and low energy consumption. The temperature control system uses a PID zero-crossing triggered thyristor and a Japanese Shimaden series intelligent dual-digital display instrument for temperature control, ensuring high temperature control accuracy, stable furnace temperature, and small temperature fluctuations. A circular graph recorder is also used to record the temperature and provide over-temperature audible and visual alarms, providing dual control to ensure the workpiece does not exceed its temperature limit.

[0003] When a solid-liquid furnace is no longer in use, the internal temperature decreases over time, resulting in a certain amount of temperature loss. This causes the temperature to rise slowly during subsequent heating, making it difficult to heat the furnace in a timely manner. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1:

[0027] Reference Figure 1-4 A heat preservation and heating device for an aluminum alloy solution treatment furnace includes a heat preservation shell 1 and a temperature control system installed inside the heat preservation shell 1. A connecting pipe 6 is connected to the bottom of one outer wall of the heat preservation shell 1, and the other end of the connecting pipe 6 is connected to a heat preservation component 8. A connecting pipe 9 is connected to the top of the other outer wall of the heat preservation shell 1, and the other end of the connecting pipe 9 is provided with an adding component 11. An inner liner 3 is provided at the top center of the heat preservation shell 1, and a container 5 is slidably connected to the inner wall of the inner liner 3. Heating pipes 4 are installed on the outer wall of the inner liner 3 at equal intervals, so that the temperature can be directly transferred to the inner liner 3 after the heating pipes 4 are started. The inner liner 3 is in close contact with the container 5, which facilitates temperature transfer and heating.

[0028] The inner wall of the heat-insulating shell 1 is provided with support blocks 2 that are evenly distributed, and the top outer wall of the support block 2 is in contact with the outer wall of the inner liner 3. The heat-insulating shell 1, the heat-insulating box 12 and the heat-insulating box 2 17 all keep the solution inside warm, reduce the rate of temperature loss, reduce heat loss and reduce resource waste.

[0029] Heating tubes 4 are installed at equal intervals on the outer side and bottom of the inner liner 3. The solution inside the insulation shell 1 is heated synchronously by the heating tubes 4 after they are turned on. The solution fills the outer wall of the inner liner 3, which makes it easy to apply the temperature to the inner liner 3, facilitates heat conduction, and makes it easy to use.

[0030] Example 2:

[0031] Reference Figure 1-3The insulation component 8 includes an insulation box 12, a solution pump 13 installed at the bottom of the outer wall of the insulation box 12, and a delivery pipe 14 installed at the output end of the solution pump 13. The hot solution in the insulation box 12 preheats the gas or liquid passing through the heat pipe 16. The gas and liquid exchange heat with the hot solution inside the insulation box 12 through the heat pipe 16 via the central pipe 15, which facilitates preheating and preheating recovery.

[0032] The outer walls of the first heat preservation box 12 are embedded with central pipes 15, and the central pipes 15 are connected to heat-conducting pipes 16 at equal intervals on one side of the outer wall. The central pipes 15 exchange heat in the first heat preservation box 12 through the heat-conducting pipes 16. After the solution in the first heat preservation box 12 cools down, the second solution pump 10 is started. The second solution pump 10 sends the solution to the second heat preservation box 17 through the delivery pipe 14. The second heat preservation box 17 sends the solution to the heat preservation shell 1 through the first solution pump 10, and the solution is circulated for heating. This facilitates the use of heat, facilitates preheating and recovery, and reduces the rate of temperature drop.

[0033] A valve 7 is installed at one end of the connecting pipe 6, and the other end of the connecting pipe 6 is connected to the top of the insulation box 12. When the temperature of the solution reaches its maximum, the valve 7 is activated to open the connecting pipe 6, so that the hot solution inside the insulation shell 1 flows into the insulation box 12 for storage. At this time, the solution pump 10 is activated to transport the cold oil in the insulation box 17 to the insulation shell 1 to balance the temperature of the solution.

[0034] Added component 11 includes insulated box 2 17 and a support frame installed on the bottom outer wall of insulated box 2 17;

[0035] A solution pump 10 is installed at the bottom of one side of the outer wall of the heat preservation box 2 17, and the other end of the connecting pipe 2 9 is connected to the input end of the solution pump 10, and the output end of the solution pump 10 is connected to the bottom inner wall of the heat preservation box 2 17.

[0036] The outer wall of the other end of the conveying pipe 14 is connected to the top of the second insulation box 17, and pressure relief valves are installed in the first insulation box 12 and the second insulation box 17.

[0037] Solution pump 10, solution pump 2, valve 7, and heating tube 4 are connected to a switch via wires, and the switch is connected to a power source via wires. Heating tube 4 heats container 5 and the solution simultaneously. After the solution is heated, the temperature is evenly transferred to container 5, which ensures uniform heating and facilitates rapid temperature rise. After heating ends, the solution stores heat, reducing the rate of temperature loss from the furnace and facilitating furnace heat preservation.

[0038] Working principle: During use, a solution is added to the inside of the insulation box 17. After the solution pump 10 is started, it delivers the solution from the insulation box 17 to the inside of the insulation shell 1. The solution is located between the inner liner 3 and the insulation shell 1. After the heating tube 4 on the outer wall of the inner liner 3 is started, it heats the metal inside the container 5 through the inner liner 3, the solution, and the container 5. The heating tube 4 heats the container 5 and the solution simultaneously. After the solution is heated, the temperature is evenly transferred to the container 5, which ensures uniform heating and facilitates rapid heating. After heating is completed, the solution stores heat, reducing the temperature loss of the furnace. The flow rate facilitates furnace insulation. When the solution temperature reaches its maximum, valve 7 is activated to open connecting pipe 6, allowing the hot solution inside insulation shell 1 to flow into insulation box 12 for storage. At this time, solution pump 10 is activated to transport cold oil from insulation box 17 to insulation shell 1, balancing the solution temperature. The hot solution in insulation box 12 preheats the gas or liquid passing through heat pipe 16. The gas and liquid exchange heat with the hot solution inside insulation box 12 through heat pipe 16 via central pipe 15, facilitating preheating and recovery.
