Technical Field

[0001] The utility model relates to the technical field of felt cleaning devices, in particular to a felt spraying device for a paper machine. Background Art

[0002] Felt, as one of the core components of paper machine, plays a vital role. Its main responsibility is to transfer the formed paper sheet from the wire section to the drying cylinder section and to perform preliminary drying and dehydration treatment on it. The state of felt has a direct impact on the quality and characteristics of paper. Since the water system in the papermaking system is recycled, impurities such as adhesives, resins, plastic sheets in the raw materials or system may contaminate the felt during the production process.

[0003] In order to ensure the quality of paper and the continuity of production, the felt needs to be cleaned regularly. High-pressure spray cleaning is a common method that can effectively remove impurities and pollutants on the felt. However, since the high-pressure spray motor is usually located near the felt, there is a lot of water vapor in the surrounding environment, and water can easily enter the motor protective cover and cannot be discharged, which may cause motor failure, thus affecting the effect of spray cleaning. Summary of the invention

One end of the spray pipe 4 is sealed and the other end is provided with a water inlet. Two through holes are respectively provided on each support plate 301, and a rotating pipe joint 8 is respectively installed in the two through holes of one support plate 301. The shell of the rotating pipe joint 8 is fixedly connected to the support plate 301, and the rotating joint of the rotating pipe joint 8 is connected to the water inlet of the spray pipe 4; the two spray pipes 4 are connected by a swing mechanism 7, and the swing mechanism 7 includes a driving gear 701, a driven gear 702 and a transmission gear 703. The other end of the spray pipe 4 passes through the through hole on the other support plate 301 and is connected to the transmission gear 703 and the driven gear 702 in sequence. The transmission gears 703 of the two spray pipes 4 are meshed, and a driving gear 701 is installed between the two driven gears 702.

[0025] In the optimized solution, the outer side of the support plate 301 is covered with a protective shell 302, and the protective shell 302 seals the swing mechanism 7 and the rotating pipe joint 8 inside thereof respectively to prevent water from entering the inside and causing corrosion.

[0026] The spray pipe 4 is provided with a plurality of linearly evenly distributed water outlets, and a high-pressure nozzle 5 is installed at the water outlet of the spray pipe 4 .

[0027] The water inlet pipe of the spray pipe 4 is connected to the high-pressure water pump through a water pipe, and the high-pressure water pump is connected to a water source through a water pipe.

[0028] In the optimized solution, the water outlets on the two spray pipes 4 are arranged in a staggered manner, so as to avoid dead corners as much as possible during the spraying process.

[0029] The driving gear 701 is an incomplete gear. During the rotation process, the driving gear 701 can only mesh with one driven gear 702 at the same time. The gear hole of the driving gear 701 is connected to the motor 1 through the connecting shaft 2.

[0030] like Figure 6 As shown, the motor 1 is connected to the motor bracket 6, and the motor bracket 6 includes a base frame 604, a screw rod 603 and a mounting plate 601.
