Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] Example

[0023] The problem to be solved is that existing stainless steel pipes produce toxic fumes when immersed in a cooling pool, and existing solution heat treatment equipment for stainless steel pipes cannot collect or treat these toxic fumes, thus affecting the health of workers.

[0024] The solution is as follows: A solution heat treatment device for stainless steel pipe fittings includes a device body 1. The device body 1 includes a heating base 2, a heating furnace 3, a cooling pool 4, and a smoke extraction device 5. The heating furnace 3 is installed on top of the heating base 2, the cooling pool 4 is installed on the right end of the heating base 2, and the smoke extraction device 5 is installed on top of the cooling pool 4. The smoke extraction device 5 includes a support block 6, a smoke collection hood 7, and an exhaust filter 8. The support block 6 is fixed to the top right end of the cooling pool 4, and the bottom right end of the smoke collection hood 7 is fixed to the top of the support block 6. The support block 6 has a rectangular structure, and the smoke collection hood 7 has a trapezoidal structure, and its interior... The bottom has a through-type structure. Two sets of the discharge filtration devices 8 are installed horizontally at equal intervals on the top of the smoke collection hood 7. A set of support rods 9, also horizontally at equal intervals, is provided on the rear bottom side of the smoke collection hood 7 and the rear top side of the cooling pool 4. The discharge filtration device 8 includes a fan device 10 and a filter cover 11. The filter cover 11 is fixed to the top output end of the fan device 10 with screws. The filter cover 11 has a cylindrical structure and a through-type internal structure. A metal mesh filter disc 12 and an activated carbon filter disc 13 are installed inside the filter cover 11, with the metal mesh filter disc 12 located below the activated carbon filter disc 13. The metal mesh filter disc 12 has several sets of horizontally equidistant flow ports 14 on its surface. Each flow port 14 has a multi-layer metal mesh filter cover 15 on top, which has an n-shaped structure. During use, the operator installs the steel pipe into the frame, then places the frame into the heating furnace 3 for heating. After heating, the steel pipe needs to be cooled. The operator removes the frame containing the steel pipe and places it in the cooling pool 4 for cooling with cooling water. When the heated frame and steel pipe come into contact with the cooling water, toxic fumes are generated. At this time, the two sets of fan devices 1 in the fume extraction device 5 activate... Upon startup, the fan unit 10 generates suction, drawing the upward-drifting smoke into the filter hood 11. The smoke collection hood 7 has a trapezoidal structure with a hollow bottom and interior, allowing for concentrated smoke output over a wide area. The smoke then passes through a metal mesh filter disc 12, where several sets of multi-layered metal mesh filter hoods 15 intercept larger oil droplets. An electrostatic field then charges and adsorbs these tiny oil droplets onto the plates, achieving smoke collection and purification. The smoke then passes through an activated carbon filter disc 13, where the activated carbon removes organic pollutants through physical adsorption. This method is suitable for treating low-concentration, high-flow-rate organic waste gas, is easy to operate, and has relatively low maintenance costs. In this way, toxic fumes can be collected, filtered, and discharged.

[0025] The bottom and top of the fan device 10 and the bottom of the filter cover 11 are all provided with locking rings 16. The surface of the locking ring 16 has several sets of fixing holes 17 distributed in a ring-shaped equidistant manner. The filter cover 11 includes a first cylinder 24 and a second cylinder 25. The second cylinder 25 is installed on the top of the first cylinder 24. Locking rings 16 are provided on the top of the first cylinder 24 and the bottom of the second cylinder 25. Filter plate support rings 18 are provided inside the first cylinder 24 and the second cylinder 25. The first cylinder 24 and the second cylinder 25 are for installing the metal mesh filter disc 12 and the activated carbon filter disc 13, respectively.

[0026] The cooling pool 4 has a collection frame 19 at its bottom, which is rectangular in shape. A residue collection filter 20 is located in the middle of the collection frame 19. The top four sides of the collection frame 19 are equipped with lifting rings 21, which are n-shaped. During cooling, the residue on the surface of the steel pipe can fall into the cooling water of the cooling pool 4, and the residue in the cooling water can settle in the collection frame 19 at the bottom. The filter in the collection frame 19 can filter the residue. When cleaning the cooling pool 4, the collection frame 19 is pulled out by the lifting rings 21, and the residue can then remain on the residue collection filter 20. In this way, the burden of cleaning the cooling pool 3 can be reduced for the staff.

[0027] The cooling pool 4 has a discharge pipe 22 at its front bottom. A discharge valve 23 is installed inside the discharge pipe 22. When discharging cooling water, workers can open the discharge valve 23 to allow the cooling water from the cooling pool 4 to drain through the discharge pipe 22.

[0028] Working principle: During operation, the worker installs the steel pipe into the frame, and then puts the frame into the heating furnace 3 for heating. After heating, the steel pipe needs to be cooled. The worker removes the frame containing the steel pipe and places it in the cooling pool 4 for cooling with cooling water. When the heated frame and steel pipe come into contact with the cooling water, toxic fumes are generated. At this time, the two sets of fans 10 in the fume extraction device 5 are activated. The fans 10 generate suction, which draws the upward-drifting fumes into the filter hood 11. The fume collection hood 7 has a trapezoidal structure and a hollow structure at the bottom and inside, which can concentrate the fumes over a large area. The fumes pass through the metal mesh filter disc 12. Then, the several sets of multi-layer metal mesh filter hoods 15 in the metal mesh filter disc 12 can intercept larger oil droplets. Then, the electrostatic field is used to charge the tiny oil droplets and adsorb them onto the electrode plates to achieve the collection and purification of oil fumes. Then the fumes pass through the activated carbon filter disc 13. The activated carbon in the activated carbon filter disc 13 can remove organic pollutants in the flue gas through physical adsorption. It is suitable for treating low-concentration, high-flow-rate organic waste gas. It is easy to operate and has relatively low maintenance costs. In this way, toxic fumes can be collected, filtered and discharged.
