Description

Technical Field

[0001] The utility model relates to the technical field of papermaking agent processing, in particular to a wet strength agent filtering device. Background Art

[0002] Wet strength agents are mainly used in the papermaking industry. The dosage varies greatly for different types of paper. The wet strength agent is now mainly PAE wet strength agent. The content of wet strength agent is mostly 12.5%. It is weakly acidic, slightly yellow, transparent, and viscous liquid. The full name of PAE wet strength agent is polyamide polyepichlorohydrin resin. It is a water-soluble resin that does not contain formaldehyde polymers. It is non-toxic and odorless. It can be papered under neutral, slightly alkaline and acidic conditions. The pH value has a wide range of applications. PAE wet strength agent has a higher reinforcing effect on wood pulp than on straw waste paper. With the increase of beating degree, the surface area of ​​pulp fiber increases, and the adsorption capacity of wet strength agent increases. The dry and wet strength of the finished paper increases accordingly. The production of wet strength agent requires a filtration device to filter the wet strength agent.

[0003] Wet strength agent filtration is to remove impurities, particles and other unnecessary components in the wet strength agent. Existing wet strength agent filters mostly use a filter screen structure to intercept solid particles and impurities in the wet strength agent on the filter medium. The filtration effect is poor, and after long-term use of the filter device, dirt will remain in the filter screen and the filter. Therefore, the inside of the filter needs to be cleaned frequently. Therefore, a filter device that can perform internal self-cleaning regularly is needed. Utility Model Content

Then, the waste water generated by the cleaning will be discharged through the sewage pipe, so there is no need for manual cleaning by personnel. The regular automatic flushing can reduce the accumulation of dirt inside the filter and affect the filtering effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-5 , in the embodiment of the present invention, a wet strength agent filtering device includes a filtering mechanism 100, and a cleaning mechanism 200 is fixedly arranged inside the filtering mechanism 100;

[0024] The filtering mechanism 100 includes a round shell 101, a support seat 102 is fixedly connected to the bottom of the round shell 101, a filter cartridge 103 is sleeved inside the round shell 101, a connecting column 104 is fixedly connected to the center position of the top of the filter cartridge 103, the top of the connecting column 104 is fixedly connected to a shaped plate 105 fixedly connected to the top of the round shell 101, a filter cartridge 108 is arranged at the bottom of the filter cartridge 103, a sealing base 107 fixedly connected to the round shell 101 is fixedly connected to the bottom of the filter cartridge 108, a water inlet pipe 115 connected to the inside of the round shell 101 is fixedly connected to the outer wall of the round shell 101, and the bottom end of the filter cartridge 103 and the filter cartridge 108 are connected to each other. The top ends are fixedly connected with a limit ring 106, and one side of the filter cartridge 108 is provided with a drain pipe 116 fixedly connected to the circular shell 101, and a solenoid valve 117 is fixedly provided on the outer wall of the drain pipe 116. The outer wall of the circular shell 101 is fixedly connected with a sewage pipe 118 connected with the interior thereof, and a solenoid valve 2 119 is fixedly provided on the outer wall of the sewage pipe 118; a plurality of filter holes 1 are provided in an annular shape at equal distances on the outer wall of the filter cartridge 103, and a plurality of filter holes 2 are provided in an annular shape at equal distances on the outer wall of the filter cartridge 2 108, and the aperture of the filter holes 2 is one tenth of the aperture of the filter holes 1; a separating ring 109 fixedly connected to the limit ring 106 is fixedly sleeved inside the circular shell 101.

[0025] Specifically, the wet strength agent is discharged into the interior of the round shell 101 through the water inlet pipe 115, and the large particles in the wet strength agent can be filtered out through the filter hole 1 on the filter cartridge 1 103 inside the round shell 101, thereby performing the first filtering treatment. Since the filter cartridge 1 103 and the filter cartridge 2 108 are connected, the wet strength agent in the filter cartridge 1 103 will then flow into the filter cartridge 2 108. The wet strength agent filtered out by the filter cartridge 1 103 still contains small particles and tiny impurities. Then, the wet strength agent can be subjected to a second filtering treatment through the filter hole 2 of the filter cartridge 108. The filtered pure liquid of the wet strength agent can be discharged through the drain pipe 116 for use in papermaking. This device can improve the filtering effect of the wet strength agent through secondary filtration, thereby obtaining a relatively pure wet strength agent. In addition, the space where the filter cartridge 1 103 and the filter cartridge 2 108 are located can be separated by the separation ring 109 provided inside the round shell 101, thereby preventing the filtered pure liquid from mixing with the wet strength agent containing impurities.

[0028] In this embodiment, when cleaning the inside of the filter device, the sewage pipe 118 is opened through the solenoid valve 119, the solenoid valve 117 is controlled to close the drain pipe 116, and then the pressure pump 114 is used to deliver clean water with high water pressure to the curved pipe 113. After that, the water pressure lifts the sealing cover 110 and then passes the clean water into the filter cartridge 108 through the drain hole 111. The clean water can flush the small particles and impurities generated by the filtration inside the filter cartridge 108. The small particles will pass through the filter hole 1 of the filter cartridge 103 with the water flow, and then the space between the round shell 101 and the filter cartridge 103 and the large particles generated by the filtration can be flushed. Then, the waste water generated by the cleaning is discharged through the sewage pipe 118, so that there is no need for manual cleaning by personnel. The regular automatic flushing can reduce the accumulation of dirt inside the filter and affect the filtering effect.

[0031] In specific implementation, when the device is automatically flushed, the output end of the driving motor 204 can drive the spur gear 203 and the spur gear 1 202 to mesh and rotate, thereby driving the rotating drum 201 and the two rotating arms 206 to rotate through the spur gear 1 202, so that the outer wall of the filter cartridge 1 103 and the filter hole 1 are cleaned by the cleaning bristles 207 on the rotating arms 206, and at the same time, the driving arm 210 and the cleaning cotton strip 209 are driven to rotate by the rotating ring 208, so that the inner wall of the filter cartridge 2 108 and the filter hole 2 can be cleaned by the cleaning cotton strip 209, thereby removing impurities blocked in the filter hole, which can improve the cleaning effect of the inside of the filter device and prevent the filter hole from being blocked too much and causing the filtering effect to decrease.
