[0030] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0031] Example 1, with reference to Figures 1-6A heat treatment equipment for metal accessories used for wastewater treatment includes a heat treatment furnace 1, a plurality of cylinders 2 are provided on the outer wall of the heat treatment furnace 1, and the telescopic ends of the plurality of cylinders 2 are fixedly connected to a furnace door 6, a rotating shaft 7 is sealed and rotatably connected to the furnace door 6, and a rotating motor 8 is provided at one end of the rotating shaft 7, a limiting platform 3 is slidably connected to the inside of the heat treatment furnace 1, and a fixed platform 5 is provided on one side of the limiting platform 3, a connecting plate 4 is fixedly connected between the limiting platform 3 and the fixed platform 5, and a rotating column 10 is rotatably connected to the outer wall on the opposite side of the limiting platform 3 and the fixed platform 5, and the other end of the rotating shaft 7 is fixedly connected to the rotating column 10 on the fixed platform 5 , the outer walls of the two rotating columns 10 on the opposite sides are fixedly connected with mounting discs 11, and the outer walls of the mounting discs 11 are hinged with multiple swing plates 16 at equal distances, one end of each swing plate 16 is fixedly connected with a receiving tube 15, and one end of each receiving tube 15 facing the center of the mounting disc 11 is slidably connected with a slide rod 20, and one end of the slide rod 20 facing the center of the mounting disc 11 is fixedly connected with a clamping ball 19, and the other end of the slide rod 20 is fixedly connected with a slide plate 22, and a high-temperature spring 21 is fixedly connected between the slide plate 22 and the receiving tube 15. A pressing mechanism is provided on each swing plate 16, and a limit table 3 and the fixed platform 5 are provided with a lifting mechanism on the outer wall of the side opposite to the fixed platform 5. First, by adjusting part of the pressing mechanism, the corresponding swing plate 16 is lifted and the swing plate 16 is in a vertical state, so that the metal pipe that needs heat treatment is placed between the limit platform 3 and the fixed platform 5. Then, by adjusting each pressing mechanism again, multiple clamping balls 19 are about to contact the surface of the metal pipe. Then, the lifting mechanism is contacted with each pressing mechanism, and force is applied to each pressing mechanism so that each clamping ball 19 is tightly against the surface of the metal pipe, thereby clamping and fixing the metal pipe and fixing it between the limit platform 3 and the fixed platform 5. The furnace door 6 is moved between the platforms 5, and then the cylinder 2 is used to move the furnace door 6 to send the metal pipe into the heat treatment furnace 1. At the same time, the furnace door 6 seals the heat treatment furnace 1, and then the rotary motor 8 is started, and the rotating column 10 connected thereto is driven to rotate through the rotating shaft 7, so that the metal pipe located in the heat treatment furnace 1 can be rotated, and in this rotation process, part of the clamping balls 19 can be lifted and then re-clamped, and because the clamping balls 19 are in contact with the surface of the metal pipe, the contact area can be greatly reduced, thereby avoiding the clamping contact position being unable to fully contact with the gas in the heat treatment furnace 1 to affect the heat treatment effect.

[0032] As a further solution in the present invention, the pressing mechanism includes an L-shaped plate, and a hollow cylinder 26 is slidably connected to the outer wall of each L-shaped plate, and a threaded rod 25 is threadedly connected to the side of the hollow cylinder 26 close to the swing plate 16, a knob 24 is fixedly connected to the outer wall of the threaded rod 25, and one end of the threaded rod 25 is rotatably connected to the rotating base 23.

[0033] As a further solution in the present invention, the outer wall of the swing plate 16 is provided with a sliding groove 17, and the inner wall of the sliding groove 17 is slidably connected with a slider 18, the rotating base 23 is hinged to the corresponding slider 18, and the threaded rod 25 can be rotated by the knob 24, and the length of the threaded rod 25 extending out of the hollow cylinder 26 can be adjusted, so that the initial angle of the swing plate 16 can be adjusted, which is convenient for placing the metal pipe that needs heat treatment, and at the same time, the clamping ball 19 can be brought into contact with the surface of metal pipes of different diameters.

[0034] As a further solution in the present invention, a limit plate 28 is fixedly connected to the outer wall of the second hollow cylinder 26, and a plurality of high-temperature springs 27 are fixedly connected between the limit plate 28 and the L-shaped plate, and a sphere 29 is fixedly connected to the outer wall of the other side of the second hollow cylinder 26.

[0035] As a further solution in the present invention, the lifting mechanism includes multiple hollow cylinders 9, one side of each of the multiple hollow cylinders 9 is threadedly connected to a threaded rod 12, and the outer wall of the threaded rod 12 is fixedly connected to a knob 14, one side of each of the multiple hollow cylinders 9 is provided with the same top plate 13, and two arc-shaped slopes are symmetrically provided on the top plate 13, one end of the threaded rod 12 is rotatably connected to the outer wall of the top plate 13, and the length of the threaded rod 12 extending out of the hollow cylinder 9 can be adjusted by the knob 14, so that the length of the threaded rod 12 extending out of the hollow cylinder 9 becomes longer and longer, so that the top plate 13 can contact each ball 29, and after contact, the length of the threaded rod 12 extending out continues to increase, so that force can be applied to the hollow cylinder 26, so that the hollow cylinder 26 compresses the high-temperature spring 27 to move, and at this time, the slide in the sliding groove 17 can be made The block 18 moves, so that the clamping ball 19 contacts the surface of the metal tube, and then the high-temperature spring 1 21 in the accommodating tube 15 is compressed until the metal tube is clamped and fixed between the limit platform 3 and the fixed platform 5; and when the rotating motor 8 rotates the metal tube in the heat treatment furnace 1 through the rotating column 10 connected to the rotating shaft 7, the balls 29 on each hollow tube 26 will move on the top plate 13. When the balls 29 pass through the arc slope on the top plate 13, the top plate 13 cannot apply force to the hollow tube 26 at this position, so that under the restoring force of the high-temperature spring 27, the clamping ball 19 is restored to the position where it is about to contact the surface of the metal tube at the beginning. When the balls 29 are separated from the arc slope on the top plate 13, the clamping ball 19 can be tightly pressed against the surface of the metal tube again, completing the clamping and fixing of the metal tube.

[0036] Working principle: First, the threaded rod 25 can be rotated by the adjustment knob 24, and the length of the threaded rod 25 extending out of the hollow cylinder 26 can be adjusted, so that the corresponding swing plate 16 is lifted, and the swing plate 16 is in a vertical state, so that the metal pipe that needs heat treatment is placed between the limit platform 3 and the fixed platform 5. Then, the threaded rod 25 can be rotated again by the knob 24, and the length of the threaded rod 25 extending out of the hollow cylinder 26 can be adjusted, so that the multiple clamping balls 19 are about to contact the surface of the metal pipe. The length of the threaded rod 12 extending out of the hollow cylinder 9 can be adjusted by turning the knob 14, so that the length of the threaded rod 12 extending out of the hollow cylinder 9 becomes longer and longer, so that the top plate 13 can contact each ball 29. After the contact, the length of the threaded rod 12 extending out is continued to be lengthened, so that a force can be applied to the hollow cylinder 26, so that the hollow cylinder 26 compresses the high-temperature spring 27 to move. At this time, the slider 18 in the sliding groove 17 can be moved, so that the clamping ball 19 contacts the surface of the metal tube, and then the high-temperature spring 27 in the accommodating cylinder 15 is released. The heat spring 21 is compressed until the metal tube is clamped and fixed between the limit platform 3 and the fixed platform 5. Then the furnace door 6 is moved by the cylinder 2 to send the metal tube into the heat treatment furnace 1. At the same time, the furnace door 6 seals the heat treatment furnace 1. Then the rotary motor 8 is started and the rotating column 10 connected to it is driven to rotate through the rotating shaft 7, so that the metal tube located in the heat treatment furnace 1 can be rotated. The balls 29 on each hollow cylinder 26 will move on the top plate 13. When the balls 29 pass through the arc slope on the top plate 13, the top plate 13 cannot move. Force is applied to the hollow cylinder 26 at this position, so that under the action of the restoring force of the high-temperature spring 27, the clamping ball 19 is restored to the position where it is about to contact the surface of the metal tube. When the ball 29 is separated from the arc slope on the top plate 13, the clamping ball 19 can be tightly pressed against the surface of the metal tube again, completing the clamping and fixing work of the metal tube. In addition, since the clamping ball 19 is in contact with the surface of the metal tube, the contact area can be greatly reduced, thereby avoiding the clamping contact position from being unable to fully contact the gas in the heat treatment furnace 1, affecting the heat treatment effect.

[0037] Example 2, reference Figure 7-Figure 8, a metal fitting heat treatment equipment for wastewater treatment, compared with Example 1, on the basis of Example 1, the slide 22 is sealed and slidably connected to the inner wall of the accommodating tube 15, and a through hole 30 is provided in the middle of the slide 22, and an air transmission channel 32 is provided inside the slide rod 20, the clamping ball 19 is hollow inside, and a plurality of exhaust holes 33 are provided on the outer wall of the clamping ball 19. When the metal pipe is clamped and fixed by multiple clamping balls 19, most of the slide rod 20 is located in the accommodating tube 15, and the high-temperature spring 21 in the accommodating tube 15 is in a compressed state. In the process of rotating the clamped metal pipe, part of the clamping balls 19 will be lifted and then reset to re-clamp and fix the metal pipe. In the process of the clamping ball 19 being lifted, the compressed high-temperature spring 21 is reset, so that the slide 22 can slide downward in the accommodating tube 15.

[0038] As a further solution in the present invention, a plurality of notches 34 are provided on the end of each exhaust hole 33 facing the outside, and the two ends of the gas supply channel 32 are respectively connected to the through hole 30 and the hollow clamping ball 19, and a one-way air intake valve 31 is provided on the outer wall of the accommodating tube 15. When the clamping ball 19 is reset to clamp and fix the metal tube again, the high-temperature spring 21 is compressed again, and the slide plate 22 slides upward, and the cycle is repeated, so that the gas in the heat treatment furnace 1 can enter the space where the high-temperature spring 21 is located through the one-way air intake valve 31, and then the gas enters the hollow clamping ball 19 through the through hole 30 and the gas supply channel 32, and then is discharged through the exhaust hole 33. In the process of clamping the metal tube by the clamping ball 19, some exhaust holes 33 will contact the surface of the metal tube, so that the gas will be discharged through the notches 34 of these exhaust holes 33, so that the gas in the heat treatment furnace 1 can be sprayed to the clamping contact position, further improving the heat treatment effect.

[0039] Working principle: When the metal tube is clamped and fixed by multiple clamping balls 19, most of the slide bar 20 is located in the accommodating tube 15, and the high-temperature spring 1 21 in the accommodating tube 15 is in a compressed state. In the process of rotating the clamped metal tube, part of the clamping balls 19 will be lifted up and then reset to clamp the metal tube again. In the process of the clamping balls 19 being lifted up, the compressed high-temperature spring 1 21 is reset, which enables the slide plate 22 to slide downward in the accommodating tube 15. When the clamping balls 19 are reset to clamp the metal tube again, the high-temperature spring 1 21 is reset. The spring 21 is newly compressed, and the slide plate 22 slides upward, and the cycle continues, so that the gas in the heat treatment furnace 1 can enter the space where the high-temperature spring 21 is located through the one-way air inlet valve 31, and then the gas enters the hollow clamping ball 19 through the through hole 30 and the gas delivery channel 32, and is then discharged through the exhaust hole 33. In the process of the clamping ball 19 clamping the metal tube, some exhaust holes 33 will contact the surface of the metal tube, so that the gas will be discharged through the notches 34 of these exhaust holes 33, so that the gas in the heat treatment furnace 1 can be sprayed to the clamping contact position, further improving the heat treatment effect.

[0041] As a further solution in the present invention, the outer walls of the tops of the two threaded sliders 37 are hinged with connecting plates 38, and the tops of the two connecting plates 38 are hinged with the same lifting plate 36. A semicircular groove 39 is provided on the top of the lifting plate 36. When it is necessary to clamp and fix the metal pipe that needs heat treatment, the metal pipe is first placed in the semicircular groove 39 of the lifting plate 36, so that the metal pipe can be stably located on the lifting plate 36. Then, the two-way threaded rod 35 is rotated by knob three 41, so that the two threaded sliders 37 on the two-way threaded rod 35 can be close to each other. The lifting plate 36 can be moved upward by the connecting plate 38, so that the metal pipe can be lifted, which is convenient for clamping and fixing it. When the clamping and fixing is completed, the two-way threaded rod 35 is reversed by knob three 41, so that the lifting plate 36 is reset.

[0042] Working principle: When it is necessary to clamp and fix the metal pipe that needs heat treatment, first place the metal pipe in the semicircular groove 39 of the lifting plate 36, so that the metal pipe can be stably located on the lifting plate 36, and then the two-way threaded rod 35 is rotated by knob three 41, so that the two threaded sliders 37 on the two-way threaded rod 35 can be close to each other, and the lifting plate 36 can be moved upward by the connecting plate 38, so that the metal pipe can be lifted, which is convenient for clamping and fixing it.
