Description

Technical Field

[0001] The utility model relates to the technical field of collecting, separating and reusing devices, in particular to a device for centrally collecting, separating and reusing papermaking water mist. Background Art

[0002] During the production process of papermaking machines, the holes of the forming mesh are often clogged by additives such as fibers, rubber and resin, resulting in mesh sticking. For this reason, a mesh washing device must be installed. Papermaking machines with a speed of more than 300m / min spray water mist from high-pressure nozzles. The water mist will spread throughout the entire manufacturing workshop, affecting the workers' sight and posing a hidden danger to production safety. The water mist centralized collection, separation and reuse device can conveniently and quickly collect the resulting water mist and reuse it.

[0003] For example, Chinese patent CN215427649U discloses a device for centralized collection, separation and reuse of water mist from the wet section of papermaking, which is characterized by comprising a high-pressure nozzle, a water collecting tank, a water receiving port, a water filter tank, a filtering mechanism, a drain pipe and a water pump.

The utility model can greatly save water resources and reduce papermaking costs through this device for centralized collection, separation and reuse of water mist from the wet section of papermaking, while protecting the environment.

[0004] Although the above-mentioned patent can greatly save water resources and protect the environment while reducing papermaking costs through the device for collecting, separating and reusing water mist in the wet section of papermaking, the high-pressure nozzle in the patent will contact the lower surface of the forming mesh when spraying water mist, and the water droplets formed by the water mist will fall to the ground under the influence of gravity, thereby wasting water resources and reducing practicality.

The left and right side walls of the inner cavity of the collecting pipe 704 are provided with baffles 706, and a mounting frame 707 is provided on the right side of the front of the support plate 2.

[0027] In this embodiment, the connecting mechanism 7 also includes a motor 708 arranged on one side of the mounting frame 707, and a rotating blade 709 is provided on the outside of the output shaft of the motor 708. The left and right side walls of the inner cavity of the collecting frame 1 are provided with support blocks 710. The upper surfaces of the left and right support blocks 710 are fixed with fixed frames 711 by bolts. By starting the motor 708, the output shaft of the motor 708 rotates with the rotating blade 709. When the rotating blade 709 rotates, wind is formed to blow toward the forming net body 4, and then the water mist and paper scraps blown off the forming net body 4 are collected through the collecting bucket 705. When the collected water mist flows to the inside of the collecting pipe 704, it gathers to form water droplets. When the rotating blade 709 rotates, airflow is generated.

During cleaning, the water mist forms water droplets which fall on the upper surface of the filter screen 712 due to gravity, and then flow into the interior of the collection frame 1 through the filter screen 712 for collection, which can save water resources.

[0030] The working principle of the above embodiment is:

[0031] By starting the water pump 702, the water inside the collection frame 1 can be pumped to the interior of the high-pressure nozzle 6 through the connecting pipe 703 and the pipeline. The high-pressure nozzle 6 sprays water mist to clean the paper scraps in the holes of the forming mesh body 4 transported by the guide roller 3. During cleaning, the water mist forms water droplets that fall on the upper surface of the filter 712 under the influence of gravity, and then flow into the interior of the collection frame 1 through the filter 712 for collection, which can save water resources. By starting the motor 708, the output shaft of the motor 708 rotates with the rotating blade 709. When the rotating blades 709 rotate, wind is formed to blow toward the forming mesh body 4, and then the water mist and paper scraps blown off the forming mesh body 4 are collected by the collecting bucket 705. When the collected water mist flows into the collecting pipe 704, it gathers to form water droplets, which are affected by gravity and fall onto the upper surface of the filter mesh 712. Then, they enter the bottom wall of the inner cavity of the collecting frame 1 for collection. The paper scraps in the water droplets stay on the upper surface of the filter mesh 712. The collected water is recycled and reused. At the same time, the left side of the input pipe 8 can be connected to an external faucet to provide a water source for the collecting frame 1.
