Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Example 1: as shown in the attached drawings 1-3, a filtering separator used in the light industry comprises a cylinder 3, an upper end enclosure 2 and a base 9, wherein the cylinder 3 is fixedly connected to the upper portion of the base 9, the upper end enclosure 2 is connected to the top end of the cylinder 3 through a flange 7 and a bolt, the bottom end of the cylinder 3 is fixedly connected with a lower end enclosure 11, the bottom end of the lower end enclosure 11 is fixedly connected with an outlet pipe 6, an inlet pipe 4 is fixedly connected to the outer side edge of the top of the cylinder 3, a support ring 8 is fixedly connected to the inner side wall of the bottom of the cylinder 3, a through hole is formed in the middle of the support ring 8, and four layers of detachable filter screens 5 which are overlapped are arranged. Sewage firstly enters the device through the inlet pipe 4, the sewage without impurities passes through the filter screen 5 and then enters the next step of the process through the outlet pipe 6, hair is tiny, hair threads can be intercepted by fins on the grid strips 54 of the filter screen 5, the hair threads are accumulated on the upper portion of the barrel body 3, when the hair reaches a certain amount, the filtering capacity can be reduced, the pressure on the upper portion of the barrel body 3 can be increased, and whether the upper end cover 2 is opened or not is determined through observing data of the pressure gauge 1 to clean the hair.

Further, the upper end enclosure 2 is connected with a pressure gauge 1. Whether the upper end enclosure 2 is opened for cleaning is determined by observing the data of the pressure gauge 1.

Furthermore, 4 positioning seats 10 are uniformly and fixedly connected above the support ring 8, and the positioning seats 10 are located on the outer side wall edge of the filter screen 5. Due to the positioning function of the positioning seat 10, the filter screen 5 can be quickly positioned when being installed, and the installation is convenient.

Further, as shown in fig. 2 to 3, the filter screen 5 includes a cylindrical section 51 and a grid net 53, a layer of horizontal grid net 53 is fixedly connected to an inner side wall of the

cylindrical section

51, and 4 clamping seats 52 are fixedly connected to an outer side wall of a top end of the cylindrical section 51. Due to the positioning function of the clamping seat 52, the filter screen 5 can be quickly positioned up and down when being installed, and the installation is convenient.

Further, the grid net 53 is fixedly connected with a plurality of grid bars 54 which are perpendicular to each other, and the distance between the grid bars 54 is 15-40 mm.

Furthermore, the grid bars 54 are finned tubes or finned bars, fins are arranged on the outer surfaces of the grid bars 54, the distance between the fins is 3-5 mm, the fins are dense and have small gaps, so that the hair filtering effect is good, different distances between the grid bars 54 have different filtering effects, various process conditions can be met, and the application range is wide.

Furthermore, the filter screens 5 are 2-5 layers, and the grid bars 54 on the filter screens 5 on the upper layer and the lower layer are arranged in a staggered mode. The distances among the grating strips 54 in different layers are different, and the grating strips 54 between the upper layer and the lower layer are arranged in a staggered mode, so that a good filtering effect can be achieved. In this embodiment, the filter screen 5 has 4 layers, two filter screens are arranged in parallel, one filter screen is used and the other filter screen is standby, and the continuous operation of the subsequent sewage treatment process is not influenced.

Through above technical scheme, sewage at first gets into this device through import pipe 4 in, the sewage that does not have debris passes filter screen 5, then gets into process on next step by outlet pipe 6, and the hair is because very tiny, and the hair silk then can be intercepted by the fin on the grid strip 54 of filter screen 5, gathers on the upper portion of barrel 3, and after the hair reaches a certain amount, the filter capacity can descend, and barrel 3 upper portion pressure can rise, through the data of observing manometer 1, confirms whether open upper cover 2 and clear up. According to the amount of hair contained in different sewage, 5 layers of different filter screens and the distance between grid bars 54 can be set, the requirements of various sewage treatment processes can be met, the filtration rate of the hair can reach more than 90%, the hair can be basically removed, the adverse effect of the hair on the next sludge fermentation evaporation treatment process is avoided, and a good application effect is achieved.
