Description

Technical Field

[0001] This utility model relates to the technical field of spray structure for paper machine drying cylinders, specifically to a drying cylinder edge spray water structure. Background Technology

[0002] In existing papermaking processes for tissue paper, adjusting the edge spray water on the drying cylinder is difficult. The edge spray water is designed to address the problem of wrinkling and knife extrusion caused by the hardening (yellow edge) of the chemical coating on the drying cylinder surface. In current designs, the spray bar is located above the vacuum roll, which presents the following problems: 1. The installation position is high, making adjustment inconvenient and posing a significant safety hazard; 2. The water mist at the nozzle is large, making blockages difficult to detect and clean online. Utility Model Content

[0005] Preferably, the chemical spray pipe is provided with a plurality of spray nozzles, and the outlet of the spray nozzles faces the bottom of the drying cylinder.

[0006] Preferably, the length of the chemical spray pipe is greater than the length of the drying cylinder, and the length of the drying cylinder scraper is greater than the length of the drying cylinder.

[0007] Preferably, the spray rod base is provided with a clamp, and the spray rod passes through the clamp and is fixed by bolts.

[0008] Preferably, the spray bar is vertically adjustable via the clamp.

[0009] Preferably, the spray rod base is further provided with a base elongated hole, through which the spray rod can be adjusted horizontally left and right.

[0010] Preferably, the bottom end of the spray bar is connected to a water pipe, and the top end is equipped with a nozzle.

[0011] Beneficial effects: This utility model improves the position of the edge spraying water spray bar of the paper machine drying cylinder by adjusting the position to the pedestrian passage below the drying cylinder, which is visible and accessible, and facilitates online cleaning of the nozzle. The horizontal direction can be adjusted through the elongated hole on the base of the spray bar, and the vertical direction can be adjusted through the clamp. Attached Figure Description

[0015] according to Figure 1-3 As shown, this utility model provides a drying cylinder spray edge water structure, including a drying cylinder 5, a drying cylinder scraper 6, a spray rod 1, a chemical baffle 3, and a chemical spray pipe 4; the chemical spray pipe 4 is placed below the drying cylinder 5 and extends in the same direction as the drying cylinder 5; the chemical baffle 3 is located below the drying cylinder 5 and is not connected to the drying cylinder 5; the spray rod 1 is fixed to both ends of the chemical baffle 3 through the spray rod base 2; the outlet of the spray rod 1 faces the bottom of the drying cylinder 5 and sprays the drying cylinder 5; the drying cylinder scraper 6 is located on the lower side of the drying cylinder 5.

[0016] The spray rod base 2 is also equipped with a base elongated hole 9 and a clamp 8. The spray rod 1 passes through the clamp 8 and is fixed by bolts. The vertical adjustment of the spray rod is achieved by the clamp. The length of the spray rod 1 is 1m-1.3m. The spray rod base 2 is fixed to the chemical baffle 3 at the bottom of the drying cylinder by bolts. The horizontal adjustment of the spray rod 1 is achieved by the base elongated hole 9 of the spray rod base 2. The base elongated hole 9 is 7cm-10cm long. The bottom end of the spray rod 1 is connected to a water pipe, and the top end is equipped with a nozzle. The position of the spray rod 1 is adjusted to the pedestrian passage below the drying cylinder 1 for convenient online adjustment and cleaning.

[0017] The chemical spray pipe 4 is equipped with several spray nozzles 7. The length of the chemical spray pipe 4 is greater than that of the drying cylinder 5. The spray nozzles 7 spray the drying cylinder. The length of the drying cylinder scraper 6 is also greater than that of the drying cylinder 5. During the drying process, the chemical substances in the slurry are dried and form yellow edges on both sides. After being softened by spraying through the spray rod 1, the yellow edges are removed by the drying cylinder scraper 6.

[0018] This utility model provides a drying cylinder edge spraying water structure. By adjusting the position of the spray rod 1, the operation of the nozzle can be observed at the channel. At the same time, the position of the spray rod can be adjusted horizontally or vertically through the elongated hole and clamp on the base of the spray rod. This is convenient, safe, and allows for online cleaning of the nozzle, avoiding nozzle blockage and yellow edge accumulation, which can lead to paper breakage. This achieves the purpose of being safer, more convenient, and more practical.
