The bottom of the overflow groove 9 is provided with a filter screen which can filter the coating liquid and then enter the coating liquid circulating system for recycling.
Furthermore, in the present embodiment, two feeding main pipes 2 are symmetrically arranged above the coating roller body 1, and a plurality of feeding branch pipes 5 are arranged on each feeding main pipe 2 at equal intervals, so as to ensure the coating efficiency and the uniformity of the coating liquid distribution.
Further, referring to fig. 5, the coating liquid circulating system includes a liquid feeding tank 12, a liquid feeding pump 13, an emulsion pump 14, a filter screen 15, a cylinder vibrating screen 16, a coating liquid circulating pump 17 and a four-way switching valve 18, wherein an outlet end of the liquid feeding tank 12 is connected to the liquid feeding pump 13, an outlet end of the liquid feeding pump 13 is connected to the emulsion pump 14, an outlet end of the emulsion pump 14 is connected to the filter screen 15, a pipeline between the emulsion pump 14 and the filter screen 15 is provided with a viscosity meter 20, an outlet end of the filter screen 15 is connected to the liquid feeding main pipe 2, an outlet of the overflow pipe 4 and an outlet of the coating dipping tank are connected to the cylinder vibrating screen 16, an outlet end of the cylinder vibrating screen 16 is connected to the coating liquid circulating pump 17, an outlet end of the coating liquid circulating pump 17 is connected to the four-way switching valve 18, the four-way switching valve 18 includes a valve port a, a valve port c and a valve port d, the valve port a is connected to the outlet end of the coating liquid circulating pump 17, the valve port b is connected to the inlet end of the liquid feeding pump 13, and c is connected to the liquid feeding tank 12. Specifically, in this example, the emulsion pump 14 is installed in a tandem design, and generates a strong shearing force in high-speed rotation by the precise combination of the rotor and the stator to crush, disperse, homogenize, and mix the powder coating liquid, thereby reducing the agglomeration of the powder in the coating liquid. Two filter screens 15 are arranged in parallel, and are installed in a one-by-one and one-standby parallel design mode, and real-time online switching is realized according to the actual blocking condition in the production process. The cylinder screen 16 adopts a design with two or more layers with different meshes, and has a vibration function with adjustable frequency, so that large-particle-size insoluble substances in the coating liquid can be fully removed. The viscometer 20 can monitor the viscosity of the coating liquid in the pipeline on line in real time.
The working process of the coating liquid circulating system is as follows:
the 1-feed tank 12 continuously supplies the coating liquid, and when the viscosity of the coating liquid is less than 400 mpa-s or the solid content is less than 3%, the circulation mode of the coating liquid adopts a pump circulation mode. The valve core of the four-way switching valve 18 is switched to valve port a → valve port b, and the circulation loop of the coating liquid at this time is: the liquid feeding pump 13 → the emulsifying pump 14 → the filter screen 15 → the coating machine 1 → the cylinder screen vibrating screen 16 → the coating liquid circulating pump 17 → the four-way switching valve 18 → the liquid feeding pump 13, because the viscosity and solid content of the coating liquid meet the requirement, the coating liquid can be directly recycled without returning to the liquid feeding tank 12.
The 2-feed tank 12 continuously supplies the coating liquid, and the circulation mode of the coating liquid adopts a barrel circulation mode when the viscosity is more than 400 mpa-s or the solid content is more than 3 percent. The valve core of the four-way switching valve 18 is switched to the valve port a → the valve port c, and the circulation loop of the coating liquid is as follows: the liquid feeding pump 13 → the emulsifying pump 14 → the filter screen 15 → the coating machine 1 → the rotary screen vibrating screen 16 → the coating liquid circulating pump 17 → the four-way switching valve 18 → the liquid feeding tank 12 → the liquid feeding pump 13, because the viscosity and solid content of the coating liquid are too high, the coating liquid needs to flow back to the liquid feeding tank 12, and the coating liquid to be sent to the coating machine 1 is ensured to meet the requirement under the dilution effect of a large amount of materials in the liquid feeding tank 12 and the continuous stirring work of the liquid feeding tank 12.
3 when the coating liquid quality is too low and needs to be discharged or tail liquid is discharged after working for a certain time, the four-way switching valve 18 is switched to the valve port a → the valve port d, and the circulation loop of the coating liquid is as follows: the liquid feeding pump 13 → the emulsifying pump 14 → the filter screen 15 → the coating machine 1 → the rotary screen vibrating screen 16 → the coating liquid circulating pump 17 → the four-way switching valve 18, and finally the circulating loop is discharged through the valve port d, thereby ensuring the quality of the whole coating liquid.
Further, a feed tank circulating pump 19 is further arranged on the feed tank 12, a liquid inlet end of the feed tank circulating pump 19 is connected with an outlet of the feed tank 12, and a liquid outlet end of the feed tank circulating pump 19 is connected to an inlet of the feed tank 12 to form a circulating loop. When the liquid level of the feed liquid tank 12 is lower than 1/5 of the tank volume, the stirrer in the tank cannot meet the requirement of full stirring due to the reduction of the coating liquid, the powder in the coating liquid is prone to layering and caking, and at the moment, the feed liquid tank circulating pump 19 needs to be started to circulate the residual coating liquid in the feed liquid tank 12, so that the auxiliary stirring effect is achieved, and the quality of the coating liquid is guaranteed. Meanwhile, the circulation flow cannot be more than 1/3 of the liquid level in the tank at the moment, so that the liquid feed pump 13 can obtain sufficient materials from the liquid feed tank 12, and the normal and stable coating operation is ensured.
Furthermore, a valve g and a valve f are respectively arranged at the inlet end and the outlet end of the emulsification pump 14, and a disc valve e is arranged in parallel at one side of the emulsification pump 14. When the powder particles put in the coating liquid are small and the powder particles and the coating liquid are mixed uniformly to meet the requirement, the emulsification pump 14 can not be started. At this time, by opening the disk valve e and closing the valve g and the valve f, the coating liquid is directly sent to the filter screen 15 through the feeding pump 13 without passing through the emulsification pump 14, thereby improving the convenience and flexibility of the system operation.
The invention realizes effective reduction of local turbulence by arranging the feeding main pipe with overflow and pressure balance and the feeding branch pipe with randomly adjustable angle and adjustable opening flatness, thereby solving the problems of shaking of the paper web to be coated, influence on coating effect such as uneven coating, generation of white sheets, even coating paper breakage and the like caused by turbulent motion of the coating liquid, and improving the coating quality and efficiency of the paper web. Meanwhile, aiming at the powder coating liquid in the embodiment, a coating liquid circulating system for full mixing, screening and filtering is arranged, so that the coating liquid main pipe and the feeding branch pipe 5 of the coating liquid supply device are ensured to obtain the coating liquid with uniform mixing, balanced viscosity and small solid content, and the feeding branch pipe 5 which can be flexibly adjusted by matching with the roll contact point and the opening flatness of the coating liquid is matched, so that the coating quality and efficiency of the paper web are greatly improved, and the requirement of homogenization production is met.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
