Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, and more specifically, it relates to a seamless steel pipe solution heat treatment device. Background Art

[0002] Solution treatment: It refers to a heat treatment process in which an alloy is heated to a constant temperature in a high-temperature single-phase region, kept at a constant temperature, and then rapidly cooled after the excess phase is fully dissolved into the solid solution to obtain a supersaturated solid solution. It is mainly to improve the plasticity and toughness of steel and alloys, and prepare for precipitation hardening treatment, etc. It makes various phases in the alloy fully dissolve, strengthens the solid solution, improves toughness and corrosion resistance, eliminates stress and softens, so as to continue processing or forming; during the solution process, metal waste residues will be generated, and it is difficult to treat the waste residues in a sealed treatment furnace. And the metal residues are recyclable materials. There is no good recycling device in the current solution device, resulting in waste of resources.

[0003] To solve the above problems, a Chinese patent with the publication (announcement) number CN218561545U discloses a solution heat treatment device for thin-walled corrosion-resistant stainless steel pipes. It includes a furnace body. There is a furnace wall inside the furnace body. A plurality of transport rollers are rotatably connected inside the furnace body. An installation plate is fixed below the transport rollers. A push plate is slidably connected to the installation plate. There is a telescopic mechanism on the right side of the push plate. A first chute is opened on the right side wall of the push plate. The left end of the telescopic mechanism is slidably connected in the first chute. The right ends of the first rotating rod and the second rotating rod are respectively fixed with a first sliding rod and a second sliding rod. A first gear and a second gear are respectively fixed on the first sliding rod and the second sliding rod. A toothed ring is arranged on the outer rings of the first gear and the second gear. A negative pressure fan is arranged on the left side of the furnace body. An air duct is arranged on the left side of the negative pressure fan. A slag filtering box is arranged below the air duct. A recycling box is arranged on the right side of the slag filtering box. During operation, the thin-walled corrosion-resistant stainless steel pipe will generate metal scraps and fall onto the installation plate at the bottom of the furnace body 1. Then, by controlling the push plate 5 to move leftward, the metal scraps are pushed to the left side of the installation plate 4 for collection. Then, the negative pressure fan 13 sucks the scraps. However, in actual operation, the push plate realizes left and right reciprocating movement through the deformation of the first rotating rod 601 and the second rotating rod 602. However, the path distance of the push plate 5 when moving left and right is limited by the maximum opening and closing angles of the first rotating rod 601 and the second rotating rod 602. Therefore, when the push plate 5 moves to the extreme right position, there will still be a gap between the push plate 5 and the left inner wall of the furnace body 1. This "gap" is the pushing blind area of the push plate 5. Since the push plate 5 cannot push out and collect the metal scraps in the pushing blind area, metal scraps will accumulate in the pushing blind area and cannot be cleaned. Workers need to manually clean the scraps in the pushing blind area regularly. Therefore, the practicality of this solution heat treatment device for thin-walled corrosion-resistant stainless steel pipes is poor. Summary of the Utility Model

[0020] Please refer to Figures 1-4As shown in the figure, a seamless steel pipe solution heat treatment device according to an embodiment of the present utility model includes a base 1 and a furnace body 2 disposed above the base 1. A furnace wall 20 is provided inside the furnace body 2, and the furnace wall 20 is in contact with the inner wall of the furnace body 2. A plurality of transmission rollers 21 are rotatably connected inside the furnace body 2, and the transmission rollers 21 are connected to the front and rear sides of the furnace body 2. A chip collecting hopper 3 is provided below the transmission rollers 21 inside the furnace body 2. The lower end of the chip collecting hopper 3 penetrates through the furnace body 2 and extends below the base 1, and a chip discharging port 30 is formed. The upper end of the chip collecting hopper 3 is formed with a chip receiving port 31, and the chip receiving port 31 has a horn-shaped structure.

[0021] During use, when working, the seamless steel pipe is placed on the transmission roller 21, and the seamless steel pipe is subjected to solution heat treatment on the transmission roller 21. During this process, metal waste chips will be generated from the seamless steel pipe and fall into the chip collecting hopper 3. The horn-shaped structure of the chip collecting hopper 3 can fully collect the metal waste chips falling above the transmission roller 21, and the waste chips collected in the chip collecting hopper 3 are discharged through the chip discharging port 30.

[0022] On the inner top wall of the base 1, two guide rods 32 are correspondingly provided on the outer circumference of the penetration position of the chip collecting hopper 3. The lower ends of the guide rods 32 are connected with limit heads 33, and guide blocks 34 are slidably arranged on the outer sides. The guide blocks 34 are fixedly connected to the chip collecting hopper 3; a spring member 35 is sleeved on the outer circumference of the guide rods 32 between the top surface of the guide blocks 34 and the inner top wall of the base 1.

[0023] During use, the installation position of the chip collecting hopper 3 is limited by the cooperation between the guide blocks 34 and the guide rods 32, ensuring the installation and movement stability of the chip collecting hopper 3.

[0024] On the inner bottom wall of the furnace body 2, an annular track 22 is fixedly provided on the outer circumference of the penetration position of the chip collecting hopper 3. An annular rail seat 23 is slidably arranged above the annular track 22. A number of first protrusions 24 are equidistantly and spacedly arranged on the top surface of the annular rail seat 23. A fixing ring 25 is formed on the outer circumference of the chip receiving port 31 of the chip collecting hopper 3, and two second protrusions 26 are correspondingly arranged on the bottom surface of the fixing ring 25; a number of teeth 27 are equidistantly and spacedly distributed on the outer peripheral surface of the annular rail seat 23. A servo motor 28 is fixedly installed below the base 1, and the output shaft of the servo motor 28 penetrates and extends into the furnace body 2 and is connected with a driving gear 29, and the driving gear 29 is in meshing cooperation with the teeth 27.

[0025] When in use, the servo motor 28 is started and drives the driving gear 29 to rotate. A sleeve adapted to the output shaft of the servo motor 28 is provided on the furnace body 2 and the base 1. The driving gear 29 rotates and drives the annular rail seat 23 to slide along the annular track 22 through the meshing cooperation between the driving gear 29 and the teeth 27. The annular track 22, the annular rail seat 23 and the chip collecting bucket 3 are coaxial. The annular rail seat 23 rotates to drive each first protrusion 24 at its upper end to move and contact or disengage with the two second protrusions 26. The number of the first protrusions 24 is even and the utility model Preferably, there are 6 first protrusions 24, and each first protrusion 24 lifts the chip collecting bucket 3 when it contacts the second protrusion 26. The movement path of the chip collecting bucket 3 is limited by the cooperation between the guide block 34 and the guide rod 32, and the spring member 35 is prompted to store energy when the chip collecting bucket 3 is lifted. When the first protrusion 24 is out of contact with the second protrusion 26, the chip collecting bucket 3 returns to its initial position due to the release of the stored energy of the spring member 35. The above action drives the chip collecting bucket 3 to vibrate up and down to ensure that the metal waste in the chip collecting bucket 3 falls fully and is discharged from the chip discharge port 30.

[0026] A filter screen 36 is arranged on the inner side of the chip receiving opening 31 , and a side discharge pipe 37 is formed on the lower part of the chip collecting bucket 3 on one side of the filter screen 36 .
