Detailed Description

The embodiment discloses a duplex filter for producing acetaminophen, which comprises two filter shells 1 connected in parallel through pipe fittings, an inner filter cylinder 2 fixedly installed in the filter shells 1, and two washing and rotating rollers 3 installed between the filter shells 1 and the inner filter cylinder 2 and used for preventing the inner filter cylinder 2 from being blocked.

As shown in fig. 1, the liquid to be filtered is divided into two branch liquid inlet pipes 5 through a total liquid inlet pipe 6, the liquid to be filtered enters a preset cavity between the filter housing 1 and the inner filter cylinder 2 of the filter in the embodiment through the branch liquid inlet pipes 5, wherein the inner filter cylinder 2 is located at the center of the filter housing 1 and is filtered by a filter membrane screen at the outer circumferential side of the inner filter cylinder 2, and the filtrate is conveyed to the next process flow through a liquid outlet pipe 7 communicated with the bottom of the inner filter cylinder 2; wherein a concentrated solution discharge pipe 1b is provided on the filter housing 1 for periodically discharging impurities.

The upper end of the washing and rotating roller 3 is provided with a rotating arm 3a, the lower end of the washing and rotating roller 3 is arranged on a rotating ring frame 3b which is sleeved on the outer periphery of the inner filter cylinder 2, wherein the diameter of the rotating ring frame 3b is slightly larger than that of the inner filter cylinder 2; a rotating disc 4c is installed at the central position of the rotating arm 3a, and particularly, the rotating disc 4c is fixed at the central position of the rotating arm 3 a; the rotating disc 4c is driven to rotate by a servo motor 4 arranged at the top of the filter shell 1; a branch liquid inlet pipe 5 and a concentrated liquid outlet pipe 1b are communicated with the side wall of the filter shell 1; the position of the branch liquid inlet pipe 5 is higher than that of the concentrated liquid discharge pipe 1 b; a brush 3c closely attached to the inner filter cartridge 2 is attached to the outer circumferential side of the washing/rotating roll 3, and the brush 3c is fixed to the outer circumferential side of the washing/rotating roll 3 to clean the filter holes clogged in the inner filter cartridge 2; a mounting plate 1a and a support base plate 1d are fixed in the filter housing 1; wherein the servo motor 4 drives a rotating disc 4c through a transmission shaft, wherein the transmission shaft is mounted on the mounting plate 1a through a bearing block 4 b; the bottom of the inner filter cylinder 2 is fixed on the support bottom plate 1 d; a liquid discharge pipe 7 communicated with the bottom of the inner filter cylinder 2 is arranged at the bottom of the filter shell 1; a plurality of support columns 1c are arranged at the bottom of the filter shell 1 and used for supporting and fixing; install in the filter shell 1 and be used for detecting liquid level sensor 8, be used for detecting the inside liquid level of filter through level sensor 8, when the liquid level was too high, judge promptly that the filter sieve hole of interior cartridge filter 2 blocks up to through the controller structure level sensor 8's liquid level signal, thereby the drive servo motor 4 drives wash and change roller 3, thereby it clears up to the filter sieve hole of interior cartridge filter 2.
