[0002] In the production and processing of steel pipes, in order to improve the corrosion resistance, appearance and other properties of the steel pipes, it is usually necessary to spray the steel pipes. After spraying, a drying operation is also required to allow the coating to dry and cure quickly.
[0003] Chinese Patent No. CN217830639U discloses a rapid drying box for an automatic spraying production line. It includes a support frame, a conveyor on top of the support frame, and a drying box mounted on the conveyor. Both sides of the drying box have inlet holes for steel pipes to pass through. This invention can quickly and effectively dry the inner wall of steel pipes. Combined with a heater, it can effectively dry the entire steel pipe, resulting in good drying effect, high efficiency, simple structure, and convenient use.
[0004] In practical applications of the aforementioned technologies, a conveyor is used to transport steel pipes to a drying chamber for drying. However, due to the contact surface between the steel pipe and the conveyor, this contact surface is difficult to achieve an effective drying effect during the drying process, resulting in the overall drying effect of the steel pipe not reaching the ideal state. Therefore, it is necessary to provide a spray drying device to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a spray drying device to solve the problems mentioned in the background art.

A drying mechanism is provided on the front of the conveyor 1.
[0034] The top of the guide rail 10 is fixedly equipped with symmetrically distributed stabilizing rods 5. The top of the drying box 4 is provided with sliding holes corresponding to the position and number of stabilizing rods 5, and the drying box 4 is slidably connected to the stabilizing rods 5 through the sliding holes.
[0035] In one embodiment, a visualization window 9 is provided on the back of the drying oven 4 to facilitate real-time observation of the drying situation inside the oven and timely adjustment of the drying operation.
[0036] In one preferred embodiment, the drying mechanism includes a hot air blower 7, which is fixedly installed on the front of the conveyor 1. The output end of the hot air blower 7 is fixedly connected to an air guide duct 8. An air outlet 16 is opened on the front of the drying box 4, and the air outlet 16 is fixedly connected to the air outlet end of the air guide duct 8, which can send hot air into the drying box 4 to dry the conveyed items.

[0038] In one preferred embodiment, symmetrically distributed balance blocks 19 are fixedly installed at the bottom of the first clamp 14 to maintain the first clamp 14 horizontally, ensure its precise contact with the steel pipe, and improve operational stability.

[0042] The working principle of this utility model is as follows: All electrical components mentioned in this document are connected to an external main controller and 220V AC mains power. The main controller can be a computer or other conventionally known control device. Parts not mentioned in this device are the same as or can be implemented using existing technology. In use, the steel pipe to be dried is placed on conveyor 1, which transports the pipe. Once the steel pipe is transported through opening 3 to the designated position inside the drying chamber 4, the transport operation stops. At this time, the hot air blower 7 has already entered its working state, and the generated hot air is input into the drying chamber 4 through the air duct 8 and air outlet 16 to dry the steel pipe. During the drying process, the electric telescopic rod 6 can be activated, and its drive end drives the guide rail 10 to move vertically. The movement of the guide rail 10 drives the movable plate 13 to move through the adjusting block 12, which in turn drives the first clamp 14 and the second clamp 18 to move downwards and place the steel pipe between them. Next, the second servo motor 20 is started, and its drive end drives the bidirectional lead screw 11 to rotate. Through the thread transmission of the left-hand and right-hand threads on the bidirectional lead screw 11, and the sliding engagement between the adjusting block 12 and the guide rail 10, the two adjusting blocks 12 move stably relative to or in opposite directions. The movement of the adjusting blocks 12 drives the movable plate 13 to move, thereby realizing the relative movement of the first clamp 14 and the second clamp 18, completing the clamping and fixing of the steel pipe. Subsequently, the clamped steel pipe is moved upward a certain distance, and the first servo motor 17 is started. Its drive end drives the second clamp 18 to rotate. Utilizing the rotational installation relationship of the first clamp 14, the steel pipe rotates under the synergistic action of the first clamp 14 and the second clamp 18, so that the bottom of the steel pipe faces the air outlet 16, allowing hot air to better penetrate the interior of the steel pipe, achieving drying of the inner wall of the steel pipe and the surface in contact with the conveyor 1. Next, the positions of the second clamp 18 and the first clamp 14 are adjusted to place the steel pipe stably on the conveyor 1. The dried steel pipe is then output from the drying chamber 4 via the conveyor 1, and the process continues to dry the next steel pipe in all directions. By adjusting the position of the steel pipe inside the drying chamber 4, this device can achieve effective drying of the entire steel pipe, avoid drying dead zones, and significantly improve the drying effect.
