Description

Technical Field

[0001] This patent relates to the field of cast pipe production technology, specifically a cast pipe spraying and drying device. Background Technology

[0002] To achieve external corrosion protection and extend service life, steel pipes are coated with an anti-corrosion coating (such as epoxy resin) on their outer wall. This coating is then dried rapidly using a drying device. Traditional cast iron pipe drying devices simply use a hot air blower to dry the outer wall of the pipe, but lack a guiding structure for the heat, allowing most of the hot air to dissipate into the surrounding environment, increasing drying time and reducing efficiency. Therefore, we propose a cast iron pipe coating and drying device. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this patent is to provide a pipe coating and drying device. This solution involves connecting a horizontal pipe to the right end of a hot air blower via a fan hood. A fixing ring is installed inside the horizontal pipe. Through the concave annular fixing ring, the hot air blown by the hot air blower can frequently contact the outer wall of the steel pipe, accelerating the drying of the anti-corrosion coating on the outer wall of the steel pipe. At the same time, the hot air will also enter the interior of the steel pipe, achieving rapid drying of both the inside and outside, shortening the drying time, and improving work efficiency.

[0004] The technical solution adopted by this patent to solve its technical problem is: a casting pipe spraying and drying device, including a hot air blower, a horizontal pipe and a steel pipe to be dried, wherein a wind hood is fixedly installed on the right end of the outer shell of the hot air blower, and the right end of the wind hood is fixed to the left end of the horizontal pipe. The inner wall of the horizontal tube is fixedly installed with fixing rings from left to right; The fixing ring is in the shape of a concave ring; A perforated plate is fixedly installed on the left end of the inner wall of the horizontal tube, and a support mechanism is installed in the middle of the right side surface of the perforated plate. The support mechanism includes a square rod, the left end of which is fixedly installed in the middle of the right side face of the perforated plate. A wheel seat is fixedly installed on the side wall of the square rod, and a support wheel is connected to the wheel seat through a rotating shaft. The edge of the support wheel is rolled on the inner side wall of the steel pipe.

[0005] Furthermore, each of the four sides of the square rod is provided with a support wheel connected by a wheel seat, and the edges of the support wheels in the four directions are respectively rolled and hung on the inner side wall of the steel pipe.

[0006] Furthermore, the horizontal tube includes a first half-tube and a second half-tube, and the two ends of the first half-tube and the second half-tube are fixed together.

[0007] Furthermore, mounting plates and mounting rings are fixedly installed on the left and right ends of the outer side walls of the first half-tube and the second half-tube, respectively. A threaded rod is integrally formed on the bottom of the mounting plate, and a nut is screwed onto the bottom end of the threaded rod through the mounting ring.

[0008] Furthermore, a baffle is provided at the right end of the horizontal tube, and an internally threaded ring is fixedly installed at the left edge of the baffle. The inner side wall of the internally threaded ring is screwed to the right side of the outer side wall of the horizontal tube.

[0009] Furthermore, the bottom of the hot air blower is integrally formed with mounting bases on both the front and rear sides, and mounting bolts are provided in the mounting holes of the mounting bases.

[0010] The beneficial effects of this patent are: 1. This solution connects a horizontal pipe to the right end of the hot air blower via a fan hood. A fixing ring is installed inside the horizontal pipe. Through the concave ring-shaped fixing ring, the hot air blown out by the hot air blower can frequently contact the outer wall of the steel pipe, accelerating the drying of the anti-corrosion coating on the outer wall of the steel pipe. At the same time, the hot air will also enter the interior of the steel pipe, achieving rapid drying of both the inside and outside, shortening the drying time, and improving work efficiency.

[0016] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0017] See Figure 1 , Figure 2 , Figure 3 , Figure 4This is a schematic diagram of the structure of this patent. A casting pipe spraying and drying device includes a hot air blower 1, a horizontal pipe 3 and a steel pipe to be dried. A fan hood 2 is fixedly installed on the right end of the outer shell of the hot air blower 1, and the right end of the fan hood 2 is fixed to the left end of the horizontal pipe 3. The inner wall of the horizontal tube 3 is fixedly installed with fixing rings 4 from left to right; The fixing ring 4 is in the shape of a concave ring; A perforated plate 5 is fixedly installed on the left end of the inner wall of the horizontal tube 3, and a support mechanism is installed in the middle of the right side surface of the perforated plate 5. To achieve external corrosion protection and extend service life, steel pipes are coated with an anti-corrosion coating (such as epoxy resin) on their outer wall. Then, a drying device is used to accelerate the drying of the anti-corrosion coating. Traditional cast iron pipe drying devices simply use a hot air blower to dry the outer wall of the steel pipe, but they lack a heat-guiding structure, which makes it easy for most of the hot air to dissipate into the surrounding environment, increasing the drying time and reducing the drying efficiency.

[0018] This solution, by setting a concave annular fixing ring 4, allows the hot air blown out by the hot air blower 1 to frequently contact the outer wall of the steel pipe, accelerating the drying of the anti-corrosion coating on the outer wall of the steel pipe. At the same time, the hot air will also enter the interior of the steel pipe, achieving rapid drying of both the inside and outside, shortening the drying time, and improving work efficiency.

[0019] The support mechanism includes a square rod 6. The left end of the square rod 6 is fixedly installed in the middle of the right side of the perforated plate 5. A wheel seat 7 is fixedly installed on the side wall of the square rod 6. A support wheel 8 is connected to the wheel seat 7 through a rotating shaft. The edge of the support wheel 8 is rolled on the inner side wall of the steel pipe.

[0020] The support wheel 8 is rolled on the inner wall of the steel pipe at the edge of the wheel body to provide internal support for the steel pipe. This leaves a certain gap between the outer wall of the steel pipe and the inner wall of the fixing ring 4, allowing hot air to quickly contact the outer wall of the steel pipe due to the concave nature of the fixing ring 4.

[0021] Specifically, the four sides of the side wall of the square rod 6 are provided with support wheels 8 connected by wheel seats 7, and the edges of the four support wheels 8 are respectively rolled and hung on the inner side wall of the steel pipe.

[0022] Setting up four types of support wheels 8 can increase the stability of the steel pipe support.

[0023] Specifically, the horizontal tube 3 includes a first half tube 9 and a second half tube 10, with the two ends of the first half tube 9 and the second half tube 10 fixed together.

[0024] By dividing the horizontal tube 3 into the first half tube 9 and the second half tube 10, it is easier to install the internal structure during the initial assembly.

[0025] Specifically, mounting plates 11 and mounting rings 13 are fixedly installed on the left and right ends of the outer side walls of the first half-pipe 9 and the second half-pipe 10, respectively. A threaded rod 12 is integrally formed at the bottom of the mounting plate 11, and a nut 14 is screwed onto the bottom end of the threaded rod 12 through the mounting ring 13.

[0026] Specifically, a baffle 15 is provided at the right end of the horizontal tube 3, and an internal threaded ring 16 is fixedly installed at the left edge of the baffle 15. The inner side wall of the internal threaded ring 16 is screwed to the right side of the outer side wall of the horizontal tube 3.

[0027] The baffle 15 can block the right side of the steel pipe, preventing the steel pipe from moving to the right with the force of the hot air.

[0028] Specifically, the bottom of the hot air blower 1 has an integrally formed mounting base 17 on both the front and rear sides, and the mounting holes of the mounting base 17 are provided with mounting bolts 18.

[0029] Working principle: The steel pipe with an external anti-corrosion coating is inserted into the horizontal pipe 3 and internally supported by the support mechanism. Hot air is blown out by the hot air blower 1. The hot air flow is guided by the fixing ring 4 to quickly and frequently contact the outer wall of the steel pipe. At the same time, the air flow also enters the interior of the steel pipe, realizing rapid heating and drying of the inside and outside of the steel pipe.

[0030] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system is not fully described. However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0031] This solution connects a horizontal pipe to the right end of the hot air blower via a fan hood. A fixing ring is installed inside the horizontal pipe. Through the concave ring-shaped fixing ring, the hot air blown out by the hot air blower can frequently contact the outer wall of the steel pipe, accelerating the drying of the anti-corrosion coating on the outer wall of the steel pipe. At the same time, the hot air will also enter the interior of the steel pipe, achieving rapid drying of both the inside and outside, shortening the drying time, and improving work efficiency.
