Description

Technical Field

[0001] This utility model relates to the field of scale removal devices, specifically to a non-invasive scale removal device. Background Technology

[0002] Circulating water coils used in the cooling system of high-temperature sterilization equipment, as heat transfer components of the heat exchange system, are at significant risk of scale buildup due to long-term operation in high-temperature environments.

[0003] Circulating water continuously exchanges heat within the coils, causing scale to gradually accumulate on the pipe walls. As the scale layer thickens, heat transfer efficiency gradually decreases. More seriously, when sufficient scale buildup occurs, it can cause structural blockages within the pipes, completely closing the fluid channels and ultimately leading to the failure of the entire heat exchange system. Current methods for unclogging the system involve disassembling and replacing the coils, but this approach is time-consuming and labor-intensive, and may result in incomplete cleaning.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of high time and labor costs associated with unclogging existing scale by disassembling and replacing coils, this utility model provides a non-invasive scale unclogging device. The non-invasive scale unclogging device includes: a coil with an inlet and a outlet, and a level gauge connected to the coil; an inlet pipe connected to the inlet, equipped with a first valve for controlling the on / off state of the inlet pipe; a descaling agent injection pipe connected to the inlet pipe, located between the inlet and the first valve, and equipped with a second valve for controlling the on / off state of the descaling agent injection pipe; a drain pipe connected to the outlet, equipped with a third valve for controlling the on / off state of the drain pipe; and a pump connected to the drain pipe, located between the outlet and the third valve, configured to evacuate the liquid from the coil.

[0006] This utility model discloses a non-invasive scale removal device, comprising a coil, an inlet pipe, and a drain pipe. The inlet pipe is connected to a descaling agent injection pipe, allowing the descaling agent to be injected into the coil through both the injection pipe and the inlet pipe, removing scale from the coil. The drain pipe is connected to a pump, which extracts the descaling agent from the coil, emptying the liquid from the pipe and coil. A level gauge is connected to the coil, allowing for easy monitoring of whether the coil is full of descaling agent. Through these features, this non-invasive scale removal device can conveniently remove scale from the coil, ensuring the continuous and stable operation of high-temperature sterilization equipment and significantly reducing operating costs.

[0007] Furthermore, an injection port is provided at the end of the descaling agent injection pipe away from the water inlet pipe, and a dust cover is provided at the injection port.

[0008] Furthermore, a liquid extraction pipe is provided between the liquid extraction pump and the drainage pipe to connect the two, and a fourth valve is provided on the liquid extraction pipe to control the opening and closing of the liquid extraction pipe.

[0009] Furthermore, the outlet end of the pump is equipped with a sewage pipe, and an observation port is provided on the sewage pipe.

[0010] Furthermore, the descaling agent injection pipe is connected to the water inlet pipe, and the liquid extraction pipe is connected to the drainage pipe via a tee fitting.

[0011] Furthermore, the drainage pipe is connected to a measuring pipe, and the level gauge is connected to the measuring pipe; a fifth valve is installed on the measuring pipe.

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0013] The inlet pipe is connected to a descaling agent injection pipe, which allows the descaling agent to be injected into the coil through both the descaling agent injection pipe and the inlet pipe to remove scale from the coil. The drain pipe is connected to a liquid pump, which can extract the descaling agent from the coil, emptying the liquid in the pipe and coil. The level gauge is connected to the coil, making it easy to observe whether the coil is full of descaling agent. This upgrade from passive to active unblocking ensures the continuous and stable operation of the high-temperature sterilization equipment and significantly reduces operating costs.
