AI Technical Summary
When the surface of the existing multi-layer composite plastic-lined pipe is not dry after spraying, it comes into contact with the inner wall of the drying device, resulting in missing coating, affecting the drying effect and increasing costs.
A spray drying device was designed, comprising a support rod and a lifting assembly. The support rod is used to support the sprayed pipe to prevent it from contacting the inner wall, and the lifting assembly is used to raise the drying chamber to avoid impact when liquid accumulates.
This effectively avoids contact between the pipe and the inner wall, ensuring the drying effect, reducing costs, and enhancing the practicality of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of surface treatment technology for plastic-lined pipes, and more specifically, to a spray drying device for surface treatment of multi-layer composite plastic-lined pipes. Background Technology
[0002] Multi-layer composite lined pipes use ordinary carbon steel pipes as the base material and are lined with thermoplastic engineering plastics with excellent chemical stability. They are formed by cold drawing or rotational molding. They have both the mechanical properties of steel pipes and the corrosion resistance, scale inhibition, and microbial growth resistance of engineering plastics. They are ideal pipes for transporting media such as acids, alkalis, salts, and corrosive gases. During the production of multi-layer composite lined pipes, the surface needs to be sprayed and then dried in a drying oven for later use.
[0003] When existing spray drying devices for surface treatment of multi-layer composite lined pipes are in use, the surface of the multi-layer composite lined pipe is not dry after spraying. Once it comes into contact with the inside of the drying device, the coating on the surface of the multi-layer composite lined pipe will be missing, which will affect the drying effect of the pipe and increase the drying cost. Therefore, there is a need to provide a spray drying device for surface treatment of multi-layer composite lined pipes. Utility Model Content
[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a spray drying device for surface treatment of multi-layer composite lined pipes. By setting up support rods, when the multi-layer composite lined pipes need to be dried, the chamber door is first opened, and then the sprayed multi-layer composite lined pipes are respectively clamped onto the surface of the support rods, so that the multi-layer composite lined pipes are erected in mid-air, so as to avoid the multi-layer composite lined pipes from contacting the inner wall of the drying chamber, thereby ensuring the drying effect of the multi-layer composite lined pipes and solving the problems existing in the prior art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a spray drying device for surface treatment of multi-layer composite lined pipes, including a drying box. Multiple support rods are fixedly connected in a rectangular array inside the drying box. Two hinges are detachably installed symmetrically along the center on one side of the front of the drying box. A box door is detachably installed on the side wall of the hinges. A door handle is welded to one side of the front of the box door. A display screen is integrally formed on the other side of the front of the drying box. A cleaning component is fixedly connected to the other side of the front of the drying box. A lifting component is fixedly connected to the bottom of the drying box.
[0006] The lifting assembly includes a stabilizing frame and a base, with multiple bases fixedly connected to the bottom of the stabilizing frame in a rectangular array.
[0007] The top of the stabilizing frame has multiple limiting grooves arranged in a rectangular array, and a hydraulic lifting cylinder can be detachably installed at the bottom of the limiting groove.
[0008] The top end of the hydraulic lifting cylinder is connected to one side of the bottom end of the drying chamber, and the extension length of the hydraulic lifting cylinder is greater than the depth of the limiting groove.
[0009] The cleaning assembly includes a support plate and a hydraulic telescopic rod. The hydraulic telescopic rod is detachably installed on the top of the side wall of the support plate, and the bottom of the support plate is connected to the other side of the front of the drying oven.
[0010] One end of the hydraulic telescopic rod is fixedly connected to a limit rod, and a ash-adhesive cylinder is movably sleeved on the surface of the limit rod.
[0011] The surface of the ash-adhesive tube is in contact with the front of the display screen, and the length of the ash-adhesive tube is greater than the width of the display screen.
[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0013] 1. In the above scheme, the spray drying device is equipped with a support rod. When the multi-layer composite plastic-lined pipe needs to be dried, the box door is opened first, and then the sprayed multi-layer composite plastic-lined pipe is clamped onto the surface of the support rod, so that the multi-layer composite plastic-lined pipe is erected in mid-air, so as to avoid the multi-layer composite plastic-lined pipe from contacting the inner wall of the drying box, thereby ensuring the drying effect of the multi-layer composite plastic-lined pipe.
[0014] 2. In the above scheme, the spray drying device is equipped with a lifting component. When liquid accumulates at the bottom of the drying box, multiple sets of hydraulic lifting cylinders inside the lifting component are activated simultaneously to make them work. Then, the hydraulic lifting cylinders will drive the drying box to move upward until the drying box is raised to the ideal height to avoid being affected by the liquid, thereby enhancing the practicality of the device.

[0026] The working process of this utility model is as follows:
[0027] In order to ensure the drying effect of the pipeline, the spray drying device is equipped with support rods 2. When the multi-layer composite lined pipe needs to be dried, the box door 4 is opened first, and then the sprayed multi-layer composite lined pipe is clamped onto the surface of the support rod 2, so that the multi-layer composite lined pipe is erected in mid-air, so as to avoid the multi-layer composite lined pipe from contacting the inner wall of the drying box 1, thereby ensuring the drying effect of the multi-layer composite lined pipe.
