Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for building water supply and drainage. Background Art

[0002] The building water supply system is a cold water supply system that brings water from the urban water supply network or the self-provided municipal water supply network into the room, and sends it to the living, production and fire-fighting water equipment through the distribution pipe, and meets the water quantity, water pressure and water quality requirements of each water use point. The building water supply system will inevitably be equipped with a filter device during the drainage process to filter the discharged sewage. The sewage often contains some plastics, particulate matter, food residues and other garbage. China has authorized a utility model patent (Announcement No.: CN218686929U) to disclose a filter device for building water supply and drainage. When the device is in use, the filter screen will be driven by the connecting rod when the pipe cover is opened, thereby pulling the filter screen upward. At this time, the garbage filtered on the filter screen can be cleaned, and the garbage cleaning process does not affect the drainage of the water inlet pipe.

[0003] Although the above device has many advantages, it still has some shortcomings in actual use: specifically, after the pipe cover is lifted up to drive the filter to move, the staff needs to lift the pipe cover with one hand and clean the garbage on the filter with the other hand when cleaning the garbage on the filter, which reduces the cleaning efficiency. At the same time, the arm is in a suspended state when lifting the pipe cover for a long time, which can easily cause discomfort to the staff's arm. Therefore, a filtering device for building water supply and drainage is proposed to address the above situation. Utility Model Content

[0004] The purpose of the utility model is to provide a filtering device for building water supply and drainage. Through the structural design of the installation block, the positioning block and the support rod, the workload of the staff when cleaning garbage is reduced, the work efficiency is improved, and the problem of low cleaning efficiency is solved.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a filtering device for building water supply and drainage, comprising a filter pipe, a filter screen, a pipe cover and a support rod, the outer surfaces of the filter pipe and the pipe cover are fixedly connected to a mounting block, the outer surface of the filter pipe is also fixedly connected to a positioning block, a through hole is provided on the top of the positioning block, a screw hole is provided on one side of the outer wall of the positioning block, a bolt is threadedly engaged with the screw hole, the support rod comprises a first rod body, the first rod body is fixed to the mounting block of the filter pipe, a contraction cavity is provided inside the support rod, an opening is provided on the top of the support rod, the opening is connected to the contraction cavity, the support rod also comprises a second rod body, the second rod body is clearance-matched with the through hole, a positioning hole is provided on the outer wall of the second rod body, a limiting portion is provided at the bottom of the second rod body, when the limiting portion clearance-matched with the contraction cavity, the second rod body is clearance-matched with the opening, and the top of the second rod body is fixedly connected to the mounting block on the pipe cover.

[0007] When the pipe cover moves upward to be separated from the filter pipe, the limiting portion contacts the top surface of the inner wall of the contraction cavity, and the bolt passes through the screw hole and extends into the positioning hole.

[0008] Furthermore, a water inlet pipe is provided on one side of the outer wall of the filter pipe, and a drain pipe is provided on the side of the outer wall of the filter pipe away from the water inlet pipe. Both the water inlet pipe and the drain pipe are connected to the inner cavity.

[0009] Furthermore, the cross-sectional projection of the tube cover is in a "T" shape, and a handle is provided on the top of the tube cover.

[0010] Furthermore, the limiting portion is a circular block, and the positioning hole and the second rod body are combined into a "T"-shaped rod.

[0011] Furthermore, the filter pipe has an inner cavity, the inner wall of the inner cavity is provided with a filter screen covering the inner cavity, and the bottom of the pipe cover is provided with a connecting rod, which is fixedly connected to the top of the filter screen.

[0012] The utility model has the following beneficial effects:

[0013] The utility model adopts the structural design of the mounting block, the positioning block and the support rod. When the pipe cover is lifted to clean the garbage on the filter screen during use, the pipe cover can be supported and limited. In this way, the staff does not need to continuously lift the pipe cover to clean the garbage, which reduces the workload of the staff when cleaning the garbage and improves work efficiency.

[0014] The utility model adopts the structural design of the contraction cavity, the opening, the second rod body and the limiting part. When in use, it can rise as the pipe cover is lifted. At the same time, the limiting part allows the second rod body to rise with a maximum stroke, thereby ensuring that the bolt is effectively positioned. In addition, the pipe cover is allowed to rise with a maximum stroke, preventing damage to the filter screen caused by pulling when the pipe cover rises.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
