[0002] A salt bath furnace is an industrial furnace that uses a molten salt solution as a heating medium and immerses the workpiece in the salt solution for heating. A salt bath furnace is an industrial furnace that uses a molten salt solution as a heating medium and immerses the workpiece in the salt solution for heating (heating can be achieved in the salt solution through metal electrodes). Depending on the operating temperature of the furnace, salts such as sodium chloride, potassium chloride, barium chloride, sodium cyanide, potassium cyanide, sodium nitrate, and potassium nitrate are commonly used as heating media. Salt bath furnaces offer fast heating speeds and uniform temperatures.

[0003] During the use of the salt bath furnace, workpieces are constantly entering the salt solution, and some debris falling from the surface of the workpiece will sink into the furnace. After a long time, the capacity of the furnace will decrease and the efficiency of heat treatment will deteriorate. Utility Model Content

The guardrail 4 is installed on the outer wall of the embedded shell 1 to intercept and protect the area around the solution hopper 2 to avoid accidental entry and cause safety problems;

[0021] The circulation structure 3 includes a filter box 8 installed on the top outer wall of the embedded shell 1, sliding blocks 9 welded at equal distances to the inner walls on both sides of the filter box 8, an interception net 10 and a filter plate 11 slidingly connected to the sliding block 9 and the inner wall of the filter box 8 respectively, and a circulation pump 13 installed on the outer wall of one end of the filter box 8.

[0022] The cross section of the embedded shell 1 is a "convex" shaped structure. There is a gap between the solution hopper 2 and the embedded shell 1. A sealing plate 14 is installed on the top outer wall of the filter box 8. The shape of the embedded shell 1 facilitates pre-embedding while hiding the pits, making it easy to use for pre-embedding.

[0023] The outer wall of the embedded shell 1 is located at the solution hopper 2 and is equipped with heating tubes 5 distributed at equal distances. The outer wall of the embedded shell 1 is located at the solution hopper 2 and is welded with a supporting protrusion. The outer wall of the bottom of the solution hopper 2 is in contact with the outer wall of the supporting protrusion. The heating tubes 5 between the embedded shell 1 and the solution hopper 2 heat the solution in the solution hopper 2 for easy use.

[0024] The cross-section of the interception net 10 is a "J"-shaped structure. Handles are welded to the top outer walls of the interception net 10 and the filter plate 11. The "J"-shaped interception net 10 intercepts and collects debris and impurities. The filter plate 11 then intercepts the impurities remaining in the solution. The circulating pump 13 then transports the solution to the solution bucket 2 through another drain pipe 6, and circulates the solution to treat it, preventing impurities and debris from filling up the solution bucket 2, thereby improving the heat treatment efficiency.

[0025] A connection port 7 is provided on the bottom outer wall of the solution hopper 2 , and a drain pipe 6 is installed on the outer wall of the embedded shell 1 at the connection port 7 , with the top end of the drain pipe 6 connected to the connection port 7 .

[0026] An outer wall of one side of the filter box 8 is connected to a water inlet pipe 12, and the other end of the water inlet pipe 12 and the output end of the circulation pump 13 are respectively connected to one end of the drain pipe 6, the circulation pump 13 and the heating tube 5 are connected to the switch through a wire, and the switch is connected to the power supply through a wire. After use, the sealing plate 14 is opened, and the intercepting net 10 and the filter plate 11 are pulled out from between the sliding blocks 9 of the filter box 8 through the handle, together with the impurities and debris, to facilitate the processing of the intercepted impurities, facilitate the processing of the solution, and improve efficiency.

[0027] Working principle: During installation, dig a hole in the required area that matches the protruding part of the bottom of the embedded shell 1, place the embedded shell 1 in the hole, and cover the top of the embedded shell 1 on the four outer walls of the hole. Then install the whole thing. Pour the required heat treatment solution into the solution bucket 2, and then install the guardrail 4 on the outer wall of the embedded shell 1 to intercept and protect the solution bucket 2 to avoid accidental entry and cause safety problems. Start the heating tube 5 between the embedded shell 1 and the solution bucket 2 to heat the solution in the solution bucket 2. When it reaches the appropriate temperature, it can be carried out. During the heat treatment operation, after the circulation pump 13 is started, the solution in a drain pipe 6 is extracted through the sealed space composed of the filter box 8 and the sealing plate 14. The circulation pump 13 draws the solution together with impurities into the filter box 8. The "J"-shaped interception net 10 intercepts and collects the debris and impurities. The filter plate 11 then intercepts the impurities remaining in the solution. The circulation pump 13 then transports the solution to the solution bucket 2 through another drain pipe 6. The solution is circulated for treatment to prevent impurities and debris from filling up the solution bucket 2, thereby improving the heat treatment efficiency.
