Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe technology, specifically to a seamless steel pipe cooling device. Background Technology

[0002] Seamless steel pipe is a type of steel pipe that has undergone cold rolling or cold drawing. Seamless steel pipe is often used to transport fluids.

[0003] During the processing of seamless steel pipes, the raw material steel bars need to be heated to 800-1000°C in a heating furnace. The heated steel bars are then pierced using a mold. The pierced steel pipes are then sent to a cooling device for cooling. After cooling, they are straightened by a straightening machine. When the steel pipes are transported to the cooling device via a conveyor belt, they are usually cooled by rinsing to remove residual impurities. However, during rinsing, the contact area between the steel pipe and the conveyor belt cannot be effectively rinsed, and impurities can easily remain on the conveyor belt at this point. These impurities can adhere to the steel pipes subsequently transported by the conveyor belt, contaminating the surface of the steel pipes, affecting their quality, and posing a safety hazard as sharp impurities may scratch workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, a seamless steel pipe cooling device is disclosed, comprising a furnace body, on which multiple high-pressure nozzles are provided, a conveyor belt runs through the furnace body, an installation plate is provided inside the furnace body, multiple baffles are evenly arranged at the lower end of the installation plate, and a first hydraulic cylinder is installed on the installation plate, which is mounted on the inner wall of the furnace body.

[0005] Preferably, a support rod slides through the mounting plate, and the support rod is fixed to the inner wall of the furnace body.

[0006] Preferably, a connecting rod is installed on each of the plurality of baffles, and a connecting plate is installed at the top of the connecting rods. A second hydraulic cylinder is installed at the lower end of the connecting plate and is mounted on the mounting plate.

[0007] Preferably, a horizontal plate is installed at the feed inlet end of the conveyor belt, the horizontal plate is installed on the front and rear frames of the conveyor belt, and partitions corresponding to the positions of the baffles are evenly installed at the lower end of the horizontal plate.

[0008] Preferably, the furnace body is provided with an exhaust device.

[0009] Preferably, a reinforcing rod is installed between the connecting rod and the baffle.

[0010] This utility model has the following beneficial effects: It has a reasonable structure and novel design. During use, the height of the baffle is adjusted according to the diameter of the mandrel. A second hydraulic cylinder drives the connecting plate to rise and fall, which in turn drives the connecting rod to rise and fall, thus changing the height of the baffle. It can be used for mandrels of different diameters, making it highly adaptable. Before feeding, the mandrel is placed on the conveyor belt, positioned between adjacent baffles. This ensures that each mandrel is positioned between adjacent baffles during transport into the furnace body. As the conveyor belt transports the mandrel, it is moved into the furnace body. Within the main body, water can wash away impurities on the mandrel and cool it down. When the mandrel is transported by the conveyor belt, the first hydraulic cylinder can drive the mounting plate to move back and forth, which in turn drives multiple baffles to move. A mandrel is placed between adjacent baffles. By moving the baffles, the mandrel can be pushed to roll within a small range, which facilitates the washing and cooling of the mandrel surface. When the mandrel rolls, it can also wash the surface of the conveyor belt below the mandrel to prevent impurities from remaining on the conveyor belt and re-adhering to the mandrel surface, causing insufficient washing of the mandrel.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Please see Figure 1-2A seamless steel pipe cooling device includes a furnace body 1, on which multiple high-pressure nozzles 2 are provided. The high-pressure nozzles 2 are connected to a water source for cooling the mandrels transported on the conveyor belt 3. The water can wash away impurities on the mandrels. The furnace body 1 is penetrated by the conveyor belt 3, which is a high-temperature resistant conveyor belt. The above is known to those skilled in the art and will not be described in detail. An installation plate 4 is provided inside the furnace body 1. Multiple baffles 5 are evenly provided at the lower end of the installation plate 4. A first hydraulic cylinder 6 is installed on the installation plate 4 and installed on the inner wall of the furnace body 1.

[0016] The first hydraulic cylinder 6 can drive the mounting plate 4 to move back and forth, thereby driving multiple baffles 5 to move. A mandrel is placed between adjacent baffles 5. By moving the baffles 5, the mandrel can be pushed to roll within a small range, which facilitates rinsing and cooling the surface of the mandrel. When the mandrel rolls, it can also rinse the surface of the conveyor belt 3 below the mandrel, preventing impurities from remaining on the conveyor belt 3 and re-adhering to the surface of the mandrel, thus preventing insufficient rinsing of the mandrel.

[0017] A support rod 7 slides through the mounting plate 4, and the support rod 7 is fixed to the inner wall of the furnace body 1;

[0018] The mounting plate 4 can be supported by the support rod 7.

[0019] Multiple baffles 5 are equipped with connecting rods 8, and a connecting plate 9 is installed at the top of the connecting rods 8. A second hydraulic cylinder 10 is installed at the lower end of the connecting plate 9, and the second hydraulic cylinder 10 is installed on the mounting plate 4.

[0020] The second hydraulic cylinder 10 can drive the connecting plate 9 to rise and fall, which in turn drives the connecting rod 8 to rise and fall, thereby changing the height of the baffle 5. It can be used for mandrels of different diameters and has strong applicability.

[0021] A horizontal plate 11 is installed at the feed inlet end of the conveyor belt 3, and the horizontal plate 11 is installed on the front and rear frames of the conveyor belt 3. A partition plate 12 corresponding to the position of the baffle 5 is evenly installed at the lower end of the horizontal plate 11.

[0022] Before feeding, the core rod is placed on the conveyor belt 3 and positioned between adjacent partitions 12 to ensure that each core rod is positioned between adjacent baffles 5 when it is transported into the furnace body 1.

[0023] The furnace body 1 is equipped with an exhaust device 13. During the core rod washing, annealing and cooling process, the generated gas, dust and impurities are extracted through the exhaust device 13. The exhaust device 13 is externally received by a collection box for collecting and treating the discharged gas. The exhaust device 13 is well known to those skilled in the art and will not be described in detail here.

[0024] A reinforcing rod, not shown in the figure, is installed between the connecting rod 8 and the baffle 5 to strengthen the connection between the connecting rod 8 and the baffle 5.

[0025] Example: In use, the height of the baffle 5 is adjusted according to the diameter of the mandrel. The connecting plate 9 is raised and lowered by the second hydraulic cylinder 10, which in turn raises and lowers the connecting rod 8, thus changing the height of the baffle 5. This allows for use with mandrels of different diameters, making it highly adaptable. Before feeding, the mandrel is placed on the conveyor belt 3, positioned between adjacent baffles 12. This ensures that each mandrel is positioned between adjacent baffles 5 when transported into the furnace body 1. As the conveyor belt 3 transports the mandrel into the furnace body 1, water can be used to... Impurities on the mandrel are washed away, and the mandrel is cooled down. When the mandrel is transported by the conveyor belt 3, the first hydraulic cylinder 6 can drive the mounting plate 4 to move back and forth, which in turn drives multiple baffles 5 to move. A mandrel is placed between adjacent baffles 5. By moving the baffles 5, the mandrel can be pushed to roll within a small range, which facilitates the washing and cooling of the mandrel surface. When the mandrel rolls, it can also wash the surface of the conveyor belt 3 below the mandrel, preventing impurities from remaining on the conveyor belt 3 and re-adhering to the mandrel surface, which would cause insufficient washing of the mandrel.
