Description

Technical Field

[0001] The present application relates to the technical field of gypsum board processing, and in particular to a drying and storage device and method for fiber cloth-faced gypsum boards. Background Art

[0002] In the production process of fiber cloth gypsum board, due to the humidity and dust problems of the raw materials, the product surface is often untidy and has a high moisture content, which affects the subsequent processing and use effect. Traditional drying methods mostly use direct hot air blowing, which has problems such as high energy consumption, poor dust control and uneven drying. Therefore, there is an urgent need for a device that can efficiently reduce dust and dehumidify, and evenly dry fiber cloth gypsum board.

[0003] When existing equipment is drying fiber cloth surface gypsum board, in order to improve the efficiency of drying processing, a multi-layer drying method is often adopted to dry multiple layers of gypsum boards stacked horizontally at intervals. However, during the drying process of the lower gypsum board, the water vapor generated is easily blocked by the upper gypsum board during the upward movement, resulting in excessive humidity in the drying chamber, affecting the drying effect. The water vapor generated by the drying of the gypsum boards between each layer is not easy to be discharged between the gypsum boards, resulting in excessive humidity inside the drying device, affecting the drying effect. In addition, the water vapor generated by the lower gypsum board is easy to enter the upper gypsum board, thereby affecting the drying efficiency of the upper gypsum board, thereby affecting the overall efficiency of the device for drying the gypsum boards.

[0004] For example, the patent document with publication number CN118168280B discloses a gypsum board drying device and a drying method thereof. In the technical solution of the patent document, multiple layers of horizontally stacked gypsum boards are dried by a variety of drying methods. Although the drying quality of the gypsum boards can be improved by uniformly drying the gypsum boards, the water vapor generated by the lower gypsum boards is easily blocked by the upper gypsum boards and cannot be discharged quickly, resulting in excessive humidity in the drying chamber, affecting the drying effect. In addition, the water vapor generated by the lower gypsum boards will also infiltrate the upper gypsum boards, thereby affecting the efficiency of the drying process of the upper gypsum boards. Therefore, there is a defect that affects the overall efficiency of the drying process of the gypsum boards. Summary of the invention

[0005] In view of this, in order to solve the problem that the water vapor generated during the drying process of the lower layer of gypsum board cannot be quickly and conveniently processed, which easily causes the humidity inside the drying device to be high for a long time, thereby affecting the drying process of the upper layer of gypsum board, and further affecting the overall efficiency of the drying process of multi-layer stacked gypsum boards, the present application provides a fiber cloth gypsum board drying storage device and method.

During the transportation of the gypsum board in the drying bin 1, it will be dried from bottom to top by the drying module. The air suction pump 26 can suck the water vapor generated in the drying process into the lower suction cavity through multiple suction holes, and then transport it to the dust removal unit on one side through the steam duct 24 on one side for dust removal.

[0047] When the dehumidification unit on one side absorbs enough moisture, the corresponding suction pump 26 can be suspended and the suction pump 26 on the other side can start working, so that the drying auxiliary module can continue to effectively assist in drying the gypsum board. At the same time, the user cleans the moisture absorbed by the dehumidification unit on this side; when the dehumidification unit on this side is cleaned and the dehumidification unit on the other side is close to saturation, the above process is repeated.

At the same time, the user performs dust removal on the dust removal unit on this side; when the dust removal unit on this side is cleaned and the dust removal unit on the other side is close to saturation, the above process is repeated.

[0073] S2, when the dust collection amount of the dust removal unit on one side is saturated, the air suction pump 26 on this side is suspended, and the air suction pump 26, the dust removal unit, the preheating unit and the dehumidification unit on the other side are started, so that the drying auxiliary module continues to work normally, and the dehumidified gas is introduced into the dust removal unit on this side through the backwashing air pipe for backwashing and dust removal; when the dust removal unit on this side is cleaned and the dust removal unit on the other side is close to saturation, the above process is repeated;

[0074] S3, when the dust absorption amount of the dehumidification unit on one side is saturated, the air suction pump 26 on this side is suspended, and the air suction pump 26, dust removal unit, preheating unit and dehumidification unit on the other side are started, so that the drying auxiliary module continues to work normally.
