Description

A filter device for household heating pipes

technical field

The utility model relates to the technical field of heating pipe filtration, in particular to a filtering device for household heating pipes.

Background technique

The heating pipe is a pipe fitting that transports warm water. During the actual process of transporting warm water, the heating pipe often becomes blocked by water impurities. In order to prevent impurities in the water from entering the inside of the heating pipe to block the heating pipe, most of the existing methods are to set filter screens in the water inlet end of the heating pipe to play the role of filtering impurities. However, under the long-term use of the heating pipe, this simple filtering device will absorb more impurities on the filter screen and thus affect the normal use of the filter screen. At this time, the filter screen needs to be taken out for cleaning or replacement, while the existing heating pipe Among them, the filter screen is fixed to the heating pipe by welding, so that the filter screen cannot be taken out for replacement or cleaning, and the heating pipe can only be replaced as a whole, which is very inconvenient.

Utility model content

The purpose of this utility model is to provide a filter device for household heating pipes to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

A filter device for household heating pipes, including a filter cartridge, a water inlet pipe and a water outlet pipe. The middle part of one side of the filter cartridge is connected to the water inlet pipe, and the top of the other side of the filter cartridge is connected to the water outlet pipe. The bottom wall of the filter cartridge is designed with a spherical structure. The bottom of the filter cartridge is connected to the sewage pipe, and the sewage pipe is provided with a control valve. The middle part of the inner cavity of the filter cartridge is provided with a first filter net. The first filter net is an arc-shaped net. Correspondingly, the water inlet end of the water outlet pipe is provided with a second filter net, the second filter net is a spherical structure design, and the convex surface of the second filter net is arranged in the filter cartridge.

As a further technical solution of the utility model, the filter cartridge is designed with a cylindrical barrel structure.

As a further technical solution of the present invention, the mesh of the second filter is smaller than the mesh of the first filter.

As a further technical solution of the utility model, the first filter screen is made of wire mesh.

As a further technical solution of the utility model, the second filter screen is made of filter cotton.

Compared with the prior art, the water flow in the utility model passes through the first filter net and the second filter net successively from the water inlet pipe to the water outlet pipe, and double-layer filtration ensures that the impurities in the water are filtered thoroughly; The bottom of the filter cartridge gathers, and the control valve is opened regularly to flush the impurities in the filter cartridge, which is easy to clean and can effectively prevent clogging.

detailed description

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Please refer to Figures 1-2, a filter device for household heating pipes, including a filter cartridge 1, a water inlet pipe 2, and a water outlet pipe 3. The filter cartridge 1 is designed in a cylindrical structure, and the middle part of one side of the filter cartridge 1 is connected to the water inlet pipe. 2. The top of the other side of the filter cartridge 1 is connected to the water outlet pipe 3. The bottom wall of the filter cartridge 1 is designed with a spherical structure. The bottom end of the filter cartridge 1 is connected to the sewage pipe 4. The sewage pipe 4 is provided with a control valve 5 , the middle part of the inner cavity of the filter cartridge 1 is provided with a first filter screen 6, the first filter screen 6 is an arc-shaped net, the concave surface of the first filter screen 6 corresponds to the water inlet pipe 2, and the outlet pipe 3 The water inlet end is provided with a second filter net 7, the second filter net 7 is a spherical structure design, the convex surface of the second filter net 7 is arranged in the filter cartridge 1, and the mesh of the second filter net 7 is smaller than the first The mesh of the filter screen 6, the first filter screen 6 is made of wire mesh, and the second filter screen 7 is made of filter cotton.

The water flow enters the filter cartridge 1 from the water inlet pipe 2, the water level rises to the top of the filter cartridge 1, and is discharged from the water outlet pipe 3, and the water flow passes through the first filter screen 6 and the second filter screen 7 in turn from the water inlet pipe 2 to the water outlet pipe 3, double-layer Filtration ensures that the impurities in the water are filtered thoroughly; and the impurities in the water accumulate at the bottom of the filter cartridge 1, and the control valve 5 is opened regularly to flush the impurities in the filter cartridge 1, which is easy to clean and can effectively prevent clogging.

The preferred implementation of this patent has been described in detail above, but this patent is not limited to the above-mentioned implementation. Within the scope of knowledge of those of ordinary skill in the art, various implementations can be made without departing from the purpose of this patent. kind of change.
