Description

A felt cloth easy-cleaning device

technical field

The utility model belongs to the field of clean production of papermaking, in particular to an easy-cleaning device for felt.

Background technique

Felt is one of the key components of the paper machine, and it is also a valuable material in the paper industry. Its main function is to transfer the formed paper from the wire section to the dryer section for drying. The state of the felt directly affects the quality of the paper surface. Due to the recycling of the water system in the papermaking system, impurities in the raw materials or the system (such as stickies, resins, plastic sheets, etc.) are likely to contaminate the felt during the production process. If the surface of the felt is contaminated and impurities appear, holes and impurities are likely to appear on the paper surface. lead to the production of substandard products. At the same time, the service life of the felt is shortened due to impurities, which will directly lead to an increase in manufacturing costs.

At present, the felt cleaning methods of domestic tissue machines need to use felt cleaning agents, gasoline and other chemical agents to clean the felt when the machine is stopped. The cleaning time and cleaning frequency are determined according to the degree of contamination of the felt. At the same time, due to the structure of the felt fiber weaving, some impurities are embedded in the gaps, and it needs to be cleaned many times with chemicals to clean it. High-frequency cleaning of the felt with chemical agents is likely to affect the air permeability of the felt, affect the evenness of the paper surface, shorten the service life of the felt, and increase the manufacturing cost.

Further, one end of the frame is fixed on the fixing seat, the end of the frame is located at one side of the running mechanism, and the high-pressure spraying device is installed on the end of the frame.

Further, the felt is arranged above the traveling mechanism, and the nozzle of the high-pressure spraying device is upward.

Further, a protective cover is provided on the traveling mechanism on the motor side.

Further, the angle of the nozzle on the high-pressure spraying device is at an angle of 90° with the traveling direction of the traveling mechanism.

Further, an automatic on-off valve is installed on the high-pressure water spraying device, and the automatic on-off valve is connected with the automatic control equipment.

Further, the high-pressure spraying device is provided with 6 nozzles, and the diameter of the nozzles is 0.2mm.

The beneficial effect of the utility model is that the high-pressure spraying device is used to spray water through high pressure, and then the high-pressure water washes the felt cloth, which not only can wash the impurities on the felt surface, but also can wash away the impurities embedded in the gaps of the felt cloth . The air permeability and service life of the felt are improved by washing with high-pressure water, and the evenness of the paper is improved at the same time.

The protective cover in the utility model can avoid electric leakage caused by high-pressure water spraying on the motor during the cleaning process of the felt cloth; the high-pressure spraying device is arranged on one side of the walking mechanism to avoid high-pressure water entering the walking mechanism during the water spraying process. The internal components of the traveling mechanism are damaged in the mechanism.
