Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1-6, a polyester polyol filtering device according to the present embodiment includes a filter cartridge 1 and a support leg 2 for supporting the filter cartridge 1, a raw material inlet 3 is disposed at an upper position of a side surface of the filter cartridge 1, a raw material outlet 4 is disposed at a bottom of the filter cartridge 1, a top cover 5 is mounted at a top of the filter cartridge 1, an exhaust valve 14 is mounted on the top cover 5, a pressure gauge 15 for detecting a pressure at the raw material inlet 3 is disposed, a rocker arm mechanism is mounted between the filter cartridge 1 and the top cover 5, a support plate 7 is mounted at an upper position in the filter cartridge 1, a plurality of mounting holes 8 are formed in the support plate 7, a bag filter 9 is hung in each mounting hole 8, and a through hole 10 communicated with the raw material inlet 3 is further formed in the support plate 7.

In order to realize tight sealing and locking of the filter cartridge 1 and the top cover 5, the filter cartridge 1 and the top cover 5 are tightly locked through a plurality of hammer type ring head bolts 6, the number of the hammer type ring head bolts 6 is eight, the hammer type ring head bolts 6 are arranged along the outer circumference of the top of the filter cartridge 1 at intervals, the hammer type ring head bolts 6 comprise hammers 16 which are arranged on the filter cartridge 1 and can turn over up and down and two parallel clamping pieces 18 arranged on the top cover 5, the tail ends of the hammers 16 are screwed with shaking rings 17, and the diameters of the shaking rings 17 are larger than the distance between the two clamping pieces 18.
