Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as figure 1 It can be seen from the structural schematic diagram of a cylindrical filter shown in the present invention that, in the cylindrical filter shown in the present invention, except that the outer cylinder 5 is made of stainless steel, the handle 1, the gland 2, the cover plate 3, the support frame 4, the collecting Parts such as pipe 6 and base 7 are all made of corrosion-resistant plastics, which can reduce the weight of the whole cylinder filter.

[0036] The cylindrical filter shown in the drawings includes a coaxial outer cylinder 5 and a collection pipe 6 . The outer cy...

Abstract

The invention discloses a cylinder filter, and belongs to the technical field of rainwater treatment devices. The cylinder filter comprises an outer cylinder with water passing holes and a collecting pipe with water passing holes, wherein the outer cylinder and the collectingpipe are coaxially arranged. The bottom end of the outer cylinder and the bottom end of the collecting pipe are detachably connected to the base. A cover plate is detachably connected to the top end of the outer cylinder. A handle is fixedly connected to the cover plate. The space between the outer cylinder and the collecting pipe is filled with a filtering medium for filtering rainwater. The diameter of the water passing holes in the outer cylinder and the diameter of the water passing holes in the collecting pipe are both smaller than the grain diameter of the filtering medium. The cylinder filter is stable and reliable in structure and can be conveniently mounted and dismounted on site, meanwhile the filtering medium can be conveniently replaced, the workload is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to a rainwater filter, which belongs to the technical field of rainwater treatment devices, in particular to a cylindrical rainwater filter for conveniently replacing filter media. Background technique [0002] As a result of urbanization, the impermeable area on the ground increases significantly, and pollutants accumulate on the ground. When it rains, the pollutants on the ground are washed away by the rainwater and enter the rainwater drainage system, and then enter the natural water body, causing water pollution. With the seriousness of urban air pollution and ground pollution, the pollution of rainwater runoff is becoming more and more serious. [0003] In the Chinese invention patent specification CN104436801A, a rainwater cyclone membrane filter is disclosed. The invention includes an inner cushion layer, a filter membrane one, a spiral flow cushion layer, a filter membrane two and a reinforcement layer from the inside to t...
