DETAILED DESCRIPTION

[0019] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0020] like Figure 1-6 As shown, a glaze line dryer includes a frame 1, a roller group, a dehumidification module 3, a heating module 4 and a heat preservation module 5. The roller group, the dehumidification module 3 and the heating module 4 are all arranged in the frame 1. The roller group divides the interior of the frame 1 into an upper drying chamber 11 and a lower drying chamber 12. In this embodiment, the heating module 4 is a heating rod, and the heating module 4 is arranged above the roller group.

[0021] The insulation module 5 is arranged on the frame 1, and the insulation module 5 includes a roller-under insulation cover 51, a roller-front insulation plate 52, a roller-rear insulation plate 53, a side insulation plate 55 and a top cover plate 56; the roller-under insulation cover 51 is arranged on the lower side of the roller shaft group, the front side of the roller-under insulation cover 51 is provided with a roller-front insulation plate 52, and the rear side of the roller-under insulation cover 51 is provided with a roller-rear insulation plate 53 to wrap the lower drying chamber 12; the top cover plate 56 is arranged directly above the roller shaft group, and the side insulation plates 55 are arranged on the left and right sides of the top cover plate 56 and extend downward to wrap the upper drying chamber 11.

[0022] In the glaze line dryer, the lower roller insulation cover 51, the front roller insulation plate 52 and the rear roller insulation plate 53 are used in combination to enclose the lower drying chamber 12, thereby preventing the heat of the lower drying chamber 12 from being lost too quickly. The top cover plate 56 and the side insulation plate 55 are used in combination to enclose the upper drying chamber 11, thereby preventing the heat of the upper drying chamber 11 from being lost too quickly, while not blocking the transportation of ceramics on the roller group. In this way, the temperature inside the frame 1 can be guaranteed and the heat loss in the frame 1 can be reduced.

[0023] It is worth noting that if Figure 4 As shown, the heat preservation module 5 further includes a roller cotton stopper 54. The roller shaft 2 is rotatably connected to the side of the frame 1. The roller cotton stopper 54 is provided on the left and right sides of the frame 1 and is located at the position where the roller shaft 2 is rotatably connected to the frame 1. Adopting a corresponding heat preservation measure, i.e., providing the roller cotton stopper 54, at the position where the roller shaft 2 is driven and connected to the frame 1 can further improve the heat preservation effect.

[0024] Optional, such as Figure 6 As shown, the roller cotton stopper 54 includes an upper cotton stopper plate 541 and a lower cotton stopper plate 542, and the upper cotton stopper plate 541 and the lower cotton stopper plate 542 are both provided with a plurality of semicircular grooves 543, wherein the semicircular grooves 543 of the upper cotton stopper plate 541 cooperate with the corresponding semicircular grooves 543 in the lower cotton stopper plate 542 to form a circular hole, and the roller shaft 2 passes through the circular hole. After the roller shaft 2 passes through the frame 1, it is rotatably connected to the frame 1 through a bearing. The portion of the roller shaft 2 that passes through the frame 1 will pass through the circular hole, thereby preventing the roller cotton stopper 54 from hindering the rotation of the roller shaft 2. Configuring the roller cotton stopper 54 into an upper cotton stopper plate 541 and a lower cotton stopper plate 542 that are independent of each other can facilitate the installation and disassembly of the roller cotton stopper 54, thereby facilitating replacement and maintenance.

[0025] Specifically, if Figure 1 and 5 As shown, the dehumidification module 3 includes a glaze line inlet and outlet exhaust hood 31. The side insulation panels 55 are disposed on the left and right sides of the top cover plate 56, forming an opening 14 on the front and rear sides of the top cover plate 56. The glaze line inlet and outlet exhaust hood 31 is disposed within the opening 14, with the input port of the glaze line inlet and outlet exhaust hood 31 facing vertically downward. Placing the glaze line inlet and outlet exhaust hood 31 at the opening 14 can, on the one hand, block some heat loss from the upper drying chamber 11, and on the other hand, extract moisture at the inlet or outlet of the rack 1, ensuring dryness within the rack 1.

[0026] Preferably, Figure 1 、 4 As shown in Figure 5, the dehumidification module 3 includes an intracavity exhaust hood 32, which is disposed in the upper drying chamber 11. The input port of the intracavity exhaust hood 32 faces the roller 2, and the dehumidification port 321 of the intracavity exhaust hood 32 extends to the outside after passing through the top cover 56. The intracavity exhaust hood 32 extracts moisture from the frame 1 and discharges it to the outside through the dehumidification port 321, thereby further dehumidifying the frame 1 and ensuring dryness within the frame 1. By directing the input port of the intracavity exhaust hood 32 toward the roller 2, moisture near the roller 2 can be extracted in a targeted manner, thereby improving the drying efficiency of the ceramic glaze.

[0027] It is worth noting that if Figure 2 and 3 As shown, the intracavity exhaust hood 32 is set in the frame 1 through a hanging bracket 13. The hanging bracket 13 includes a first angle bracket 131, a second angle bracket 132, and a screw 133. The first end of the first angle bracket 131 is connected to the inner wall of the frame 1, the first end of the second angle bracket 132 is connected to the outer wall of the intracavity exhaust hood 32, the second end of the first angle bracket 131 is parallel to the second end of the second angle bracket 132, and the screw 133 passes through the second end of the first angle bracket 131 and the second end of the second angle bracket 132 to fix the first angle bracket 131 and the second angle bracket 132. Using the first angle bracket 131 and the second angle bracket 132 to suspend the intracavity exhaust hood 32 in the frame 1 can facilitate the installation and removal of the intracavity exhaust hood 32, thereby facilitating maintenance and repair.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
