Description

Technical Field

[0001] This utility model relates to the technical field of heating hot water pipes, and in particular to a secondary heating pipe network flushing device. Background Technology

[0002] The secondary heating network is a crucial component of a centralized heating system. Its primary function is to transport hot water generated at heat exchange stations to individual users and to collect return water, forming a circulating heating network. A typical secondary heating network consists of supply pipes, return pipes, circulating pumps, makeup water pumps, valves, compensators, and branch pipes for users. Its core function is to use the circulating pumps to power the hot water heated at the heat exchange stations to the user terminals. After releasing heat, the water returns to the heat exchange stations through the return pipes for reheating, forming a closed-loop system. If the water pressure is insufficient, the makeup water pumps will activate to maintain stable system pressure. Mechanical or chemical cleaning can remove scale from the pipes and reduce resistance.

[0003] The existing Chinese utility model patent with application number CN202020919590.9 relates to a flushing device for a heating hot water pipe network, including a power box, a fixing plate, a push rod, a sealing ring, a cleaning rod, and a steel wire brush, etc. It can effectively observe the internal cleanliness of the heating pipe network through lighting beads and a monitor, and ensure the flushing quality.

[0004] However, the above-mentioned device is only suitable for straight pipes in actual use. For pipes with complex bends, it is necessary to flush them by adding chemical cleaning agents and circulating water. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a thermal secondary pipeline flushing device that discharges settled dirt through a sewage discharge device, filters the water flow in the pipeline through a filtration device, and enables the filtration device to have self-cleaning capability through an auxiliary device, thereby improving the practicality of the device.

[0006] This utility model discloses a secondary thermal pipeline flushing device, comprising a sewage discharge device, a filter device, and an auxiliary device. The filter device is installed on the sewage discharge device, and the auxiliary device is installed on the sewage discharge device. The sewage discharge device discharges the settled dirt from the equipment, the filter device filters the water flow in the pipeline, and the auxiliary device enables the filter device to have self-cleaning capability, thereby improving the practicality of the device.

[0007] Preferably, the sewage discharge device includes a main pipeline, a filter box, a sewage discharge pipe, a geared motor, a sewage discharge valve, and spiral blades. The filter box is installed on the main pipeline, and the sewage discharge pipe is connected to the lower left side of the filter box. The geared motor is installed on the left end of the sewage discharge pipe, and spiral blades are installed inside the sewage discharge pipe. The output end of the geared motor is connected to the spiral blades. A sludge discharge outlet is provided on the lower left side of the sewage discharge pipe, and a sewage discharge valve is installed on the sludge discharge outlet. The opening and closing of the sludge discharge is controlled by the sewage discharge valve. The geared motor is turned on to transmit power to the spiral blades, which drive the spiral blades to rotate. The rotating spiral blades transport the dirt at the bottom of the filter box to the left side of the sewage discharge pipe for storage, thereby discharging the settled dirt and improving the practicality of the device.

[0008] Preferably, both the drain pipe and the left side of the spiral blade are conical. By making both the drain pipe and the left side of the spiral blade conical, the effective output flow of the left side of the drain pipe is reduced. This, combined with the rotation of the spiral blade, allows solid precipitates to accumulate more quickly in the left side of the drain pipe. Timely control of the drain valve opening can reduce the amount of liquid discharged during the sedimentation process, thus improving the practicality of the device.

[0009] Preferably, the filtration device includes a support pipe, support blades, and a filter screen. The filter screen is installed at an angle in the upper part of the filter box, with the right side of the filter screen tilting downwards to the lower side of the main pipeline connected to the right side. The upper part of the filter screen is located above the main pipeline connected to the left side of the filter box. The support pipe is installed at an angle in the filter box, and multiple sets of support blades are installed on the front and rear sides of the support pipe, providing auxiliary support for the filter screen. The filter screen filters impurities in the liquid, and the support pipe and support blades provide overall support and fixation for the filter screen, reducing local deformation caused by local impact of solid impurities in the water flow on the filter screen and improving the practicality of the device.

[0010] Preferably, the device also includes a three-way solenoid valve and a quick connector. Two sets of three-way solenoid valves are connected in series on the main pipeline on the left side of the filter box, and a quick connector is installed on the input end of the three-way solenoid valve on the left side. The first set of three-way solenoid valves on the left side of the filter box controls the overall on / off of the main pipeline circuit and discharges the circulating water during the flushing process. The second set of three-way solenoid valves on the left side connects the output end of the external booster pump to the main pipeline during the flushing process. The quick connector facilitates the quick installation and removal of the pipeline, pressurizes the main pipeline circuit to complete the flushing, and improves the practicality of the device.

[0011] Preferably, the auxiliary device includes a guide rod, a mounting frame, and a vibration motor. The left side of the support tube is connected to the outside of the filter box, the guide rod is inserted into the support tube, and the left side of the guide rod is connected to the mounting frame, on which the vibration motor is mounted. By periodically turning on the vibration motor, power is transmitted to the guide rod, causing the guide rod, support tube, and support blades to vibrate, thereby causing the filter screen to vibrate periodically, completing the self-cleaning of the filter screen, accelerating the removal of deposits from the filter screen surface, and improving the practicality of the device.

[0012] Preferably, it also includes an internal threaded seat and a screw. The internal threaded seat is installed in the lower part of the support tube, and the screw is provided on the lower end face of the smooth rod. By rotating the smooth rod, the internal threaded seat and the screw are connected, thereby fixing the position of the spiral blade and preventing the vibrating motor from detaching from the support tube during vibration, thus improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the sewage discharge device discharges the settled dirt from the equipment, the filter device filters the water flow in the pipeline, and the auxiliary device enables the filter device to have self-cleaning ability, thereby improving the practicality of the device.
