Description

Technical Field

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

[0002] Drain pipes for buildings are mainly divided into rigid polyvinyl chloride pipes, core foam pipes, rigid polyvinyl chloride silencer pipes, etc. Its function is to discharge rainwater and sewage. These rainwater and sewage are often mixed with some construction debris, which often clog the drain pipes if not treated. The drainage pipe filter device is a device that intercepts construction debris and helps discharge rainwater and sewage.

[0003] The existing building drainage pipe filtration is: a filter net is added to the connection between two drainage pipes to intercept building debris through the filter net.

[0004] Although this method can realize the operation of filtering construction debris through the drain pipe, it still has the following disadvantages: if the filter is not cleaned for a long time, the construction debris on the filter tends to accumulate and may cause the drain pipe to be blocked. To clean the filter, the two drain pipes connecting the filter are often disconnected, and then the filter is cleaned and the debris on the drain outlet of the drain pipe is removed. Disassembling the drainage pipe and cleaning the filter is not only cumbersome, but also the filter is hidden in the drain pipe. The operator cannot directly observe the real-time status of the filter, which is easy to miss the cleaning time, resulting in the blockage of the drain pipe, and the practicality is insufficient.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 to Figure 4As shown, this embodiment proposes a drainage pipe filter device for construction, wherein the water inlet 13 and the water outlet 14 are arranged on the fixed seat 1. The slag box 2 is threadedly connected to the lower end of the fixed seat 1. A sealing structure is arranged between the slag box 2 and the fixed seat 1 to seal the slag box 2. The water inlet connecting pipe 3 is fixedly arranged on the water inlet 13, the first locking structure is arranged on the water inlet connecting pipe 3, and is used to lock and connect the water inlet drainage pipe 32, the second locking structure is arranged on the water outlet 14, and is used to lock and connect the water outlet drainage pipe 4, the filter assembly 6 is arranged on the water outlet 14, and is detachably connected to the water outlet 14, and the slag box 2 is made of a transparent material. The filter assembly 6 in this embodiment is arranged on the fixed seat 1, and the construction debris will accumulate in the slag box 2 under the action of gravity, reducing the debris passing through the filter assembly 6, so that the filter assembly 6 is not easy to be blocked.

[0028] The slag storage box 2 in this embodiment is a cylindrical structure, and the distance from the port of the water inlet connecting pipe 3 entering the slag storage box 2 to the bottom of the slag storage box 2 is smaller than the distance from the port of the slag storage box 2. This design makes the construction debris in the sewage discharged from the water inlet connecting pipe 3 closer to the bottom of the slag storage box 2 when discharged, and will gather to the bottom of the box under the action of gravity, thereby reducing the construction debris passing through the filter screen 611 and reducing the possibility of clogging the filter screen 611.

[0029] The fixing seat 1 in this embodiment includes a limiting end 11 and a connecting end 12, the limiting end 11 and the connecting end 12 are integrally formed, the projection surface of the limiting end 11 is a circular structure, and the external thread 121 is provided on the connecting end 12, which is threadedly connected to the slag storage box 2. The projection surface of the limiting end 11 in the vertical direction falls within the projection surface of the connecting end 12 in the vertical direction.

[0030] The first locking structure in this embodiment includes a limiting bolt 5, which is arranged at the water inlet 13, and a locking member 31 is fixedly arranged at the end of the water inlet connecting pipe 3. A thread is arranged on the outer wall of the locking member 31, and it is threadedly connected with the limiting bolt 5. The projection surface area of ​​the locking member 31 in the vertical direction close to the end of the water inlet 13 is smaller than the projection surface area of ​​the locking member 31 in the vertical direction away from the end of the water inlet 13. The locking notch 311 is arranged on the locking member 31 to lock the drain pipe. The locking member 31 in this embodiment is supported by an elastic material. The limiting bolt 5 is rotated to reduce the locking notch 311. The inner wall diameter of the locking member 31 is gradually reduced according to the diameter of the actual connected drain pipe until it abuts and locks the drain pipe and the water inlet connecting pipe 3.

[0031] The second locking structure in this embodiment is the same as the first locking structure, and there are two locking notches 311, which are respectively arranged at both ends of the locking member 31, and the locking member 31 is made of elastic material. Such a design ensures that the locking member 31 has a certain degree of ductility, and ensures that when the limit bolt 5 approaches or separates from the locking member 31, the locking member 31 breaks due to deformation.

[0032] The sealing structure in this embodiment includes a sealing ring 111, which is arranged between the slag storage box 2 and the fixed seat 1. The sealing ring 111 is made of rubber material and is fixedly connected to the fixed seat 1. The design of the sealing ring 111 ensures that the slag storage box 2 and the fixed seat 1 are sealed, and sewage will not seep out from between the slag storage box 2 and the fixed seat 1.
