Description

Technical Field

[0001] This utility model relates to the field of cast iron pipe production, specifically a rust removal and oil spraying device for cast iron pipe production and processing. Background Technology

[0002] During the casting process, rust and impurities may remain on the surface of cast iron pipes. These need to be removed by rust removal to ensure the quality of subsequent processes. At the same time, in order to prevent environmental corrosion and extend service life, the surface of cast iron pipes is usually sprayed with oil after rust removal.

[0003] Utility model patent application number 2024200341630 discloses a rust removal and oil spraying device for the production and processing of cast iron pipes. This device rotates the clamping threaded rod by turning the clamping knob, which in turn causes the clamping plate to clamp the cast iron pipe fitting. Then, the sliding of the slider within slide rail one and slide rail two pushes the cast iron pipe fitting into the housing. Then, the operation of the delivery pump extracts oil from the storage tank, pressurizes it, and sprays it out through the oil spraying head, thereby achieving oil spraying lubrication of the cast iron pipe fitting. Finally, multiple cast iron pipe fittings can be oil sprayed and lubricated, which greatly improves the production efficiency.

[0004] However, in practical applications, the device can only spray oil on the upper surface of the pipe fittings. The oil on the lower surface is applied by the oil on the upper surface sliding down, resulting in uneven oil application. Furthermore, the rust removal operation on the surface of the cast iron pipe requires manual processing or the use of other equipment, which is inconvenient and urgently needs improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a rust removal and oil spraying device for the production and processing of cast iron pipes.

[0006] To solve the above problems, the technical solution of this utility model is: a rust removal and oil spraying device for the production and processing of cast iron pipes, including a base plate, a plurality of support seats for supporting the cast iron pipes are installed on the top of the base plate, and a rust removal component, a flushing component, a drying component and an oil spraying component of the same design are installed on the top of the base plate above the support seats from left to right.

[0007] The rust removal assembly includes a fixing frame, an annular tube installed on the inner side of the fixing frame, multiple nozzles provided on the inner side of the annular tube, and an input tube connected to the lower part of the outer side;

[0008] The top of the base plate is also equipped with multiple drive components for moving the cast iron pipe. Each drive component includes a second fixed frame. A horizontal plate is movably installed on the upper inner side of the second fixed frame. Two ear plates are installed at the bottom of the horizontal plate. A drive roller is rotatably installed between the two ear plates. A motor is installed on the side of one ear plate. The output shaft of the motor is connected to the drive roller.

[0009] Furthermore, the support base includes a fixed base, with fixed columns symmetrically arranged on both sides of the fixed base, and a roller is rotatably installed between the fixed base and the fixed columns. The two rollers are referred to as a V-shaped design.

[0010] Furthermore, two flushing components are arranged side by side, and the input pipes of the two flushing components are connected to the water supply pipe. The nozzles of the rust removal component, flushing component, and oil spraying component are high-pressure nozzles.

[0011] Furthermore, three drying components are arranged side by side, and the input pipes of the three drying components are connected to the air guide pipe, and the nozzles of the drying components are flat nozzles.

[0012] Furthermore, a protective ring is fixedly connected to the top edge of the base plate, and a baffle is fixedly connected inside the protective ring between the drying component and the oil spraying component. The baffle divides the inner side of the protective ring into a wastewater tank and an oil collection tank.

[0013] Furthermore, the upper part of both sides of the fixing frame is symmetrically provided with sliding grooves, and I-shaped sliders are slidably connected in the sliding grooves. The two ends of the horizontal plate are respectively connected to the two sliders.

[0014] Furthermore, an electric actuator is installed on the top of the second fixing frame, and the output end of the electric actuator is connected to the horizontal plate.

[0015] The advantages of this utility model compared with the existing technology are as follows: the cast iron pipe of this utility model is sequentially derusted by the rust removal component, rinsed by the rinsing component, dried by the drying component, and then conveyed to the oil spraying component for oil spraying treatment, realizing continuous treatment of rust removal and oil spraying. Through the design of the annular pipe and multiple nozzles, the cast iron pipe can be treated and sprayed with oil in all directions. Attached Figure Description

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

[0022] like Figures 1 to 4 As shown, a rust removal and oil spraying device for cast iron pipe production and processing includes a base plate 1. The top of the base plate 1 is equipped with a plurality of support seats 2 for supporting the cast iron pipe. The support seat 2 includes a fixed seat 17. Fixed columns 18 are symmetrically arranged on both sides of the fixed seat 17, and rollers 19 are rotatably installed between the fixed seat 17 and the fixed columns 18. The two rollers 19 are referred to as V-shaped design.

[0023] The cast iron pipe is supported by two V-shaped rollers 19, which facilitates the movement of the cast iron pipe.

[0024] From left to right, the bottom plate 1 is equipped with a rust removal component 3, a flushing component 4, a drying component 5, and an oil spraying component 6, all with the same design. The rust removal component 3 includes a fixing frame 7, with an annular pipe 8 installed inside the fixing frame 7. The annular pipe 8 has multiple nozzles 9 inside and an input pipe 10 connected to its lower outer side. Two flushing components 4 are arranged side by side, and the input pipes 10 of the two flushing components 4 are connected to a water supply pipe 20. The nozzles 9 of the rust removal component 3, flushing component 4, and oil spraying component 6 are high-pressure nozzles. Three drying components 5 are arranged side by side, and the input pipes 10 of the three drying components 5 are connected to an air guide pipe 21. The nozzles 9 of the drying components 5 are flat nozzles. A protective ring 22 is fixed to the top edge of the bottom plate 1. Inside the protective ring 22, between the drying component 5 and the oil spraying component 6, a baffle 23 is fixed, which divides the inside of the protective ring 22 into a wastewater tank and an oil collection tank.

[0025] The input pipe 10 of the rust removal component 3 is connected to the rust remover supply pump. The rust removal component 3 sprays rust remover onto the surface of the cast iron pipe, removing rust and other impurities through a chemical reaction. The water supply pipe 20 of the rinsing component 4 is connected to the clean water supply pump. The rinsing component 4 sprays clean water onto the surface of the cast iron pipe, rinsing the surface of the cast iron pipe. The air guide pipe 21 is connected to the hot air blower. The drying component 5 blows hot air onto the surface of the cast iron pipe, achieving rapid drying and preventing the surface of the cast iron pipe from rusting again. The input pipe 10 of the oil spraying component 6 is connected to the oil pump. The oil spraying component 6 sprays oil onto the surface of the cast iron pipe, achieving oiling treatment on the surface of the cast iron pipe.

[0026] The top of the base plate 1 is also equipped with a plurality of drive components 11 for moving the cast iron pipe. Each drive component 11 includes a second fixed frame 12. A horizontal plate 13 is movably installed on the upper inner side of the second fixed frame 12. Two ear plates 14 are installed at the bottom of the horizontal plate 13. A drive roller 15 is rotatably installed between the two ear plates 14. A motor 16 is installed on the side of one ear plate 14. The output shaft of the motor 16 is connected to the drive roller 15. An electric push rod 25 is installed on the top of the second fixed frame 12. The output end of the electric push rod 25 is connected to the horizontal plate 13.

[0027] The extension of the electric actuator 25 causes the horizontal plate 13 to lower the position of the drive roller 15, pressing it against the top surface of the cast iron pipe. The motor 16 drives the drive roller 15 to rotate, causing the drive roller 15 to move the cast iron pipe, thus conveying the cast iron pipe. The motor 16 is a variable frequency motor, which can adjust the conveying speed of the cast iron pipe as needed to avoid incomplete rust removal due to excessive conveying speed. In practical applications, the number of rust removal components 3 can also be increased as needed.

[0028] In practical use, this device is controlled by an external PLC controller. The cast iron pipe is placed on the support base 2, and its end is moved to the inside of the fixed frame 12. The electric push rod 25 extends, causing the horizontal plate 13 to lower the position of the drive roller 15 and press it against the top surface of the cast iron pipe. The motor 16 drives the drive roller 15 to rotate, causing the drive roller 15 to move the cast iron pipe, thus realizing the conveying of the cast iron pipe. The cast iron pipe is sequentially conveyed to the oil spraying assembly 6 for oil spraying after passing through the rust removal assembly 3 for rust removal, the rinsing assembly 4 for rinsing, and the drying assembly 5 for drying. Through the design of the annular pipe 8 and multiple nozzles 9, the cast iron pipe can be treated and sprayed with oil from all directions.
