Description

Technical Field

[0001] This utility model relates to the field of papermaking blanket processing technology, specifically a drying device for papermaking blanket processing. Background Technology

[0002] Papermaking felts are fabrics made of high-strength fibers, installed in the press and drying sections of papermaking machines to transfer paper, absorb moisture, and aid in dehydration and setting. Based on their placement on the papermaking machine, they can be categorized as wet felts, top felts, and dry felts. Papermaking felts are available in both woven and knitted types. In the processing of papermaking felts, the drying device is one of the key pieces of equipment, primarily used to remove residual moisture or solvents from the felts during impregnation, forming, or heat setting processes, ensuring the physical properties and service life of the felts.

[0003] Existing drying methods mostly use hot air drying, which uses a hot air circulation system to blow hot air onto the surface of the blanket to achieve uniform drying. However, hot air drying has limited penetration depth and is not suitable for thick or high moisture content blankets. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for papermaking felt processing, comprising an extrusion mechanism and a drying mechanism. The extrusion mechanism includes two sets of uprights, on which a first extrusion roller and a second extrusion roller are arranged. The drying mechanism includes a first side frame and a second side frame, with multiple sets of drying components arranged between the first side frame and the second side frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please seeFigures 1-5 This utility model provides a technical solution: a drying device for papermaking blanket processing, including an extrusion mechanism 1 and a drying mechanism 2. The extrusion mechanism 1 includes two sets of uprights 11, on which a first extrusion roller 12 and a second extrusion roller 13 are arranged. The drying mechanism 2 includes a first side frame 21 and a second side frame 22. Multiple sets of drying components 23 are arranged between the first side frame 21 and the second side frame 22. The drying component 23 includes a rotating roller 231 and an electric heating tube 232. The rotating roller 231 is configured as a cavity structure, and the electric heating tube 232 extends into the cavity of the rotating roller 231.

[0025] like Figure 5 As shown, the papermaking blanket to be dried first passes through the extrusion mechanism 1 and then around the drying mechanism 2. The first extrusion roller 12 of the extrusion mechanism 1 contacts the upper surface of the papermaking blanket, and the second extrusion roller 13 of the extrusion mechanism 1 contacts the lower surface of the papermaking blanket. When the papermaking blanket moves under the drive of external force, it is squeezed by the first extrusion roller 12 and the second extrusion roller 13, squeezing out some of the moisture in the papermaking blanket and improving the subsequent drying quality. Even blankets with high moisture content can be dried uniformly.

[0026] The rotating roller 231 and the electric heating tube 232 are separate structures. The rotating roller 231 can rotate relative to the first side frame 21, while the electric heating tube 232 is fixed. When the electric heating tube 232 is energized, it heats the chamber of the rotating roller 231, thereby heating the surface of the rotating roller 231. When the rotating roller 231 comes into contact with the papermaking blanket, it heats and dries the papermaking blanket.

[0027] like Figure 5 As shown, the papermaking blanket has a serpentine structure that wraps around multiple sets of drying components 23. When the papermaking blanket moves under the drive of external force, the upper and lower surfaces of the papermaking blanket are in full contact with the multiple sets of drying components 23. The drying components 23 heat the upper and lower surfaces of the papermaking blanket, causing the remaining moisture in the papermaking blanket to evaporate and achieving uniform drying. The number of drying components 23 can be selectively set according to actual usage requirements. During the movement of the papermaking blanket, it is fully dried. The entire drying device can be directly installed on the papermaking blanket production line.

[0028] The first extrusion roller 12 and the second extrusion roller 13 are located between the two sets of uprights 11, and screws 14 are fixedly installed at both ends of the first extrusion roller 12 and the second extrusion roller 13.

[0029] The upright frame 11 has a slot 15, through which the screws 14 at both ends of the first extrusion roller 12 and the second extrusion roller 13 pass.

[0030] The first extrusion roller 12 is fixedly connected to the upright frame 11 by a locking nut 16, and the second extrusion roller 13 is fixedly connected to the upright frame 11 by a locking nut 16.

[0031] An extrusion channel is formed between the first extrusion roller 12 and the second extrusion roller 13.

[0032] The position of the first extrusion roller 12 on the stand 11 is adjustable, and the position of the second extrusion roller 13 on the stand 11 is also adjustable. By adjusting the positions of the first extrusion roller 12 and the second extrusion roller 13 on the stand 11, the width of the extrusion channel can be adjusted accordingly. The width of the extrusion channel can be adjusted according to the thickness of the papermaking felt, so that the extrusion channel of the extrusion mechanism 1 can be adapted to the papermaking felt, thereby realizing the extrusion of the papermaking felt. It is suitable for papermaking felts of different thicknesses.

[0033] One end of the rotating roller 231 is connected to the first side frame 21 by a bearing. The rotating roller 231 can rotate relative to the first side frame 21. When the papermaking blanket moves, the rotating roller 231 rotates accordingly. The rotating roller 231 and the papermaking blanket are in full contact, so as to dry the papermaking blanket evenly.

[0034] Among them, the electric heating tube 232 is installed on the second side frame 22. The electric heating tube 232 is fixed and the electric heating tube 232 is energized to heat the rotating roller 231, so that the surface of the rotating roller 231 generates heat, and the papermaking blanket is heated by the heat to dry the papermaking blanket.

[0035] The drying mechanism 2 is located on one side of the extrusion mechanism 1. The papermaking blanket to be dried is first squeezed out of the water by the extrusion mechanism 1, and then dried by the drying mechanism 2, thereby improving the drying quality of the papermaking blanket.

[0036] The extrusion mechanism 1 and the drying mechanism 2 are both fixedly mounted on the mounting base plate 3. The mounting base plate 3 has a mounting groove 31. The entire drying device is installed and fixed by the mounting base plate 3 and installed in the designated position for use.

[0037] Working principle: During use, the width of the extrusion channel of the extrusion mechanism 1 is adjusted according to the thickness of the papermaking felt to adapt the extrusion channel of the extrusion mechanism 1 to the papermaking felt. The number of drying components 23 can be selectively set according to actual usage requirements. The papermaking felt to be dried first passes through the extrusion channel of the extrusion mechanism 1, and then passes around the multiple drying components 23 of the drying mechanism 2 in a serpentine structure. The electric heating tube 232 is energized and heated to heat the chamber of the rotating roller 231, so that the surface of the rotating roller 231 is heated. When the papermaking felt moves under the drive of external force, it is squeezed by the first extrusion roller 12 and the second extrusion roller 13, squeezing out some of the water in the papermaking felt. The upper and lower surfaces of the papermaking felt are in full contact with the multiple drying components 23. The drying components 23 heat the upper and lower surfaces of the papermaking felt, so that the remaining water in the papermaking felt evaporates, achieving uniform drying.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
