In order to overcome the shortcomings of the prior art that the household filter needs to be manually drained many times, the operation is inconvenient, and it is difficult to ensure the sewage effect during implementation, the utility model connects the water inlet pipe 1 and the return water pipe 5 through the sewage pipe 7 , so that it forms a sewage channel, and a sewage valve 6 controlled by a controller 4 is installed on the sewage pipe 7 . During blowdown, the controller 4 opens the blowdown valve 6, and introduces the water flow of the water inlet pipe 1 to the return pipe 5 through the blowdown pipe 7 for blowdown; after blowdown is finished, close the blowdown valve 6 for normal heating. Due to the technical scheme adopted by the utility model, the water flow power of the heating system itself is used to directly flush and discharge the filtered dirt, so as to ensure that the heating system is not blocked, the dirt does not accumulate, and the dirt does not adhere, effectively ensuring The heating equipment and metering instruments are working normally.

Description

automatic filter drainer

(1) Technical field:

The utility model relates to an automatic filter sewage discharger used in a household central heating system.

(2) Background technology

For central heating systems, due to the influence of the degree of cleanliness of the water source of the heating system, as well as the wear, corrosion and aging of pipes, pipe fittings, and user cooling equipment, it is inevitable that dirt will appear in the water flow of the heating system. The accumulation and adhesion of this kind of dirt on the user's indoor heating equipment will deteriorate the heat transfer conditions and cause the heating quality to decline. Especially when the sewage flows through the meter, it will also accumulate, adhere to or even block the heating meter, resulting in inaccurate meter measurement, which will cause the user's heating system to not work normally.

In the prior art, a centralized filtering sewage device is installed at the water source of the heating system, and a household filter is installed at the entrance of each user. The household filter consists of an inclined tee, a filter screen and a plug at the bottom of the inclined pipe, and is usually set on the user's heating water inlet pipe. The inclined pipe of the inclined tee forms a sewage holding pipe. The dirt and impurities in the heating water pipe are usually blocked by the filter screen in the sewage holding pipe. It is necessary to periodically open the plug under the inclined pipe to remove the dirt. Since the sewage in the heating system is randomly generated, and the volume of the sewage pipe is limited, in order to ensure the smooth flow of the pipeline and the sewage discharge effect, it is necessary to perform sewage discharge many times during a heating period. However, this periodic sewage discharge needs to be done manually, especially special tools are needed to open the sewage plug at the bottom of the filter for sewage discharge, which is inconvenient to operate and difficult to guarantee the sewage discharge effect.

(3) Contents of the invention

In order to overcome the problems existing in the prior art that household filters need to be manually drained many times, the operation is inconvenient, and it is difficult to ensure the sewage effect during implementation, the utility model proposes an automatic filter sewage device.

The purpose of this utility model is achieved in this way: the water inlet pipe is connected with the return water pipe through the sewage pipe to form a sewage channel, and a sewage valve controlled by a controller is installed on the sewage channel. During the sewage discharge, the sewage valve is opened by the controller, and the water flow of the water supply pipeline is introduced into the return water pipeline through the sewage pipe, and the water flow power of the heating system is used to directly flush and discharge the filtered sewage for sewage discharge.

The technical solution adopted by the utility model can introduce the water flow of the water inlet pipe into the return water pipe, and use the water flow power of the heating system itself to directly flush and discharge the filtered dirt, so as to realize the automatic filtering of the dirt and water in the heating system of the user. Automatic and regular sewage discharge improves the effect of filtering sewage on the user's heating system, thereby ensuring that the indoor heating system is not blocked, dirt does not accumulate, and adheres, so that the user's indoor heating equipment can work normally, especially the long-life of the household heating meter normal work.

(5) Specific implementation methods

Embodiment one

In this embodiment, a sewage discharge pipe 7 is set between the water supply pipe 1 and the return pipe 5 for user heating, and a sewage discharge valve 6 is arranged on the sewage discharge pipe 7. The opening and closing of the sewage discharge valve 6 is controlled by the controller 4, so that the water supply pipeline The water flow of 1 enters the return pipe 5 through the sewage pipe 7, and uses the water flow power of the heating system itself to directly flush and discharge the filtered dirt.

This embodiment includes a water supply pipe 1 , an inclined tee pipe 2 , a filter screen 3 , a controller 4 , a water return pipe 5 , a sewage valve 6 and a sewage pipe 7 . In the specific implementation, the plug at the bottom of the inclined three-way pipe 2 in the prior art is opened, and the inclined three-way pipe 2 is communicated with the return water pipe 5 with a water pipe, so that the sewage pipe 7 is formed between the water supply pipe 1 and the return water pipe 5 .

The blowdown valve 6 is installed on any position of the blowdown pipe 7 , and its control shaft is connected with the controller 4 . The controller 4 can control the opening or closing of the sewage valve 6 regularly through its built-in micro-motor: when discharging sewage, open the sewage valve 6, and use the water flow power of the heating system itself to make the water flow of the water supply pipe 1 pass through the sewage pipe 7 Enter the return pipe 7; after the blowdown operation is completed, close the blowdown valve 6 for normal heating.

Embodiment two

In this embodiment, a sewage discharge pipe 7 is set between the water supply pipe 1 and the return pipe 5 for user heating, and a sewage discharge valve 6 is arranged on the sewage discharge pipe 7. The opening and closing of the sewage discharge valve 6 is controlled by the controller 4, so that the water supply pipeline The water flow of 1 enters the return pipe 5 through the sewage pipe 7, and uses the water flow power of the heating system itself to directly flush and discharge the filtered dirt.

This embodiment includes a water supply pipe 1 , a filter screen 3 , a controller 4 , a water return pipe 5 , a sewage valve 6 and a sewage pipe 7 . In the specific implementation, the original inclined tee pipe 2 is removed, and a sewage discharge pipe 7 is installed between the water inlet pipe 1 and the return water pipe 5, and the two ends of the sewage discharge pipe 7 are respectively connected with the water inlet pipe 1 and the return water pipe 5 , so that it forms a sewage channel, and a sewage valve 6 controlled by a controller 4 is installed on the sewage pipe 7 .
