[0010] Further, the filter hole has a diameter of 3-8mm.
[0011] Further, the detachable filter drum is provided with a secondary filter screen, and the diameter of the secondary filter screen is smaller than that of the filter hole.
[0012] Further, the end cover filter hole aperture of the water inlet end of the detachable filter cartridge is larger than the end cover filter hole aperture of the water outlet end of the detachable filter cartridge.
[0013] The above technical scheme has the following beneficial effects:
[0014] The filter device has the following effects: the filter device filters twice through the detachable filter cartridge and the filter filler arranged in the detachable filter cartridge, thereby greatly improving the filtering effect.
[0015] The detachable filter cartridge is in the shape of a cylinder or a flat-head cone, and the cylinder or the flat-head cone facilitates the installation of the filter device and the connection with the water inlet.
[0016] The detachable filter cartridge is composed of a superior arc segment and an inferior arc segment, a plurality of filter holes are arranged on the superior arc segment and the inferior arc segment, the end cover is fixed on the superior arc segment, the inferior arc segment is the detachable door, one side of the inferior arc segment is hinged to the superior arc segment, and the other side is movably installed on the superior arc segment by means of a bolt.
[0017] The detachable filter cartridge is provided with a secondary filter screen, the aperture of the secondary filter screen is smaller than the aperture of the filter hole, large garbage is filtered through the detachable filter cartridge, and small garbage is filtered through the secondary filter screen, so that large and small garbage can be filtered and intercepted.
[0018] The end cover filter hole aperture of the water inlet end of the detachable filter cartridge is larger than the end cover filter hole aperture of the water outlet end of the detachable filter cartridge. BRIEF DESCRIPTION OF DRAWINGS
[0019] Figure 1 It is a structural schematic view of the embodiment 1.
[0020] Figure 2 It is a structural schematic view of the embodiment 1. Figure 1 It is a sectional view of A-A.
[0021] Figure 3The structure diagram of the detachable filter cartridge in the specific embodiment 1.
[0022] In the drawings, 1 is a detachable filter cartridge, 2 is an end cover, 3 is a filter hole, 4 is a detachable door, and 5 is a hinge. DETAILED DESCRIPTION Specific embodiment 1:
[0024] Referring to Figures 1 to 3 As shown in the drawings, a sewage treatment filtering device includes a detachable filter cartridge 1 and filter fillers. The detachable filter cartridge 1 is in the shape of a cylinder or a flat-head cone, which is convenient for cleaning and is the best embodiment. The filter fillers are selected according to the existing corresponding filter fillers according to the different water quality of the filtered sewage. The filter fillers are provided with different particle sizes according to the different places of use. When the sewage treatment filtering device is located at the water inlet end of a sewage treatment tank, the particle size of the filter fillers is larger than that when the sewage treatment filtering device is located at the water outlet end of the sewage treatment tank. Because the filter fillers are arranged at the water inlet end, they mainly intercept large particles and waste, and the particle size of the filter fillers is correspondingly set to be large, which is convenient for interception and is not easy to be clogged. If the filter fillers are arranged at the water outlet end, the particle size of the filter fillers can be set to be small to intercept small suspended particles.
[0025] The filter fillers are arranged in the detachable filter cartridge 1. The detachable filter cartridge 1 is provided with an end cover 2 at both the water inlet end and the water outlet end. The surface of the detachable filter cartridge 1 and the end cover 2 is provided with a plurality of filter holes 3. The diameter of the filter holes 3 is 3-8 mm, and the diameter of the filter holes 3 is selected according to the different sizes of the filter holes according to the different filtered sewage. The diameter of the filter holes of the end cover 2 at the water inlet end of the detachable filter cartridge 1 is larger than that of the end cover 2 at the water outlet end of the detachable filter cartridge 1.
[0026] A material taking hole is arranged on the detachable filter cartridge 1. The material taking hole is correspondingly provided with a detachable door 4 which is movably arranged.
[0027] In the specific embodiment, the detachable filter cartridge 1 is composed of a superior arc segment and an inferior arc segment. A plurality of filter holes are arranged on the superior arc segment and the inferior arc segment. The end cover is welded and fixed on the superior arc segment. The inferior arc segment is the detachable door 4. One side of the inferior arc segment is hingedly connected to the superior arc segment through a hinge 5, and the other side is movably installed on the superior arc segment through a bolt. Possibly, the bolt can be replaced by a buckle.
