Description

Technical Field

[0001] The present application belongs to the technical field of thermal pipelines, and specifically relates to a thermal pipeline filtering mechanism. Background Art

[0002] Filters or filtering mechanisms are usually required in thermal pipelines to ensure the cleanliness and safety of the transported medium. Thermal pipeline filtering mechanisms are usually used to filter fine impurities and particles to prevent damage to equipment in the pipeline or contamination of the medium.

The structure is reasonable. The utility model is provided with a filtering mechanism, the filtering mechanism is installed inside the processing box, and the processing box is connected to the thermal pipeline. The filtering mechanism has multi-layer filtering and detachable effects, so that the filtering mechanism can perform multi-layer filtering treatment on the thermal pipeline during the process of conveying hot water. At the same time, the filtering mechanism can also be disassembled and cleaned to avoid the situation where the filtering effect of the filtering mechanism is reduced when it is used for a long time. The filtering treatment of the thermal pipeline is effectively realized, and the stability and filtering effect of the thermal pipeline filtering device are improved.

[0004] The device is provided with a plurality of filter plates inside the processing box. When there are a large number of impurities and particles attached to the plurality of filter plates, the flow rate of the liquid inside the thermal pipe will be affected. In this case, the filter plates need to be disassembled and cleaned. However, the filter plates of the device are installed inside the processing box and sealed by a cover plate, so that outsiders cannot observe the impurities and particles attached to the filter plates inside the processing box in time and deal with them. In this way, the flow of the liquid inside the thermal pipe is affected. Therefore, a thermal pipe filtering mechanism is provided. Utility Model Content

[0025] The implementation principle of an embodiment of a thermal pipeline filtering mechanism of the present application is as follows: under normal conditions, external liquid enters the interior of the filtering treatment box 1 through the liquid inlet pipe 5 and the thermal pipeline 1 3, and the liquid is filtered and treated through the filter assembly 2, and the treated liquid is discharged through the thermal pipeline 2 6 and the drain pipe 8. When the treated liquid is discharged through the thermal pipeline 2 6 and the drain pipe 8, the flow rate of the discharged liquid can be detected by the set liquid flow rate sensor 9 at this time. When the liquid flow rate sensor 9 detects that the flow rate of the liquid inside the thermal pipeline 2 6 is lower than the set value, the liquid flow rate sensor 9 feeds back a signal to the control element inside the controller housing 12.

[0026] When the alarm 11 sounds an alarm, the control element controls the electric control valve 1 4 and the thermal pipe 2 6 to close. At this time, the one-way valve on the outer surface of the connecting pipe 15 opens, allowing the liquid inside the liquid inlet pipe 5 to enter the discharge pipe 8 through the connecting pipe 15 and be discharged. In this way, the liquid inside the pipeline will not be interrupted and the normal circulation of the liquid is maintained. A circular filter is installed near the middle of the outer surface of the connecting pipe 15 to filter the liquid flowing through the connecting pipe 15.
