Description

Technical Field

[0001] The utility model belongs to the technical field of scale inhibition, and in particular relates to a slow-release scale inhibition tube. Background Art

[0002] In the field of water supply and drainage, as the use of pipelines increases, scale is prone to form. Scale is a kind of insoluble salt, the main components of which are calcium carbonate, magnesium hydroxide, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride, magnesium chloride, etc. Scale not only causes great harm to the human body, but also harms various heat exchange and heating equipment and pipelines in industrial production, causing equipment damage or scrapping, and even causing explosions of pressurized equipment such as boilers. Scale is also the most fundamental cause of energy waste.

[0003] At present, scale inhibitors are mainly used to remove scale. For example, a Chinese invention patent with publication number CN109694136A discloses a scale inhibitor tube and its production process, and discloses that FOF scale inhibitor is injected between the outer filter element and the inner filter element to form an equal FOF scale inhibitor filtration layer on the entire filter element to play a scale inhibition role. However, the scale inhibitor in the patent is filled between the outer filter element and the inner filter element, and will be released quickly, making it difficult to achieve slow release. In addition, the filling amount is large, the consumables are large, and the cost is high. Utility Model Content

[0006] A slow-release scale-inhibiting pipe comprises a filter element and a scale-inhibiting pipe body. A plurality of scale-inhibiting pipe bodies are arranged in the filter element, and the scale-inhibiting pipe bodies contain a scale inhibitor capable of slow release.

[0007] Furthermore, a sewage plug is detachably provided at one end of the filter element, and a filter element end cover is detachably provided at the other end opposite to the filter element.

[0008] Furthermore, the sewage drain plug is arranged on the filter element through a threaded seat.

[0009] Furthermore, the threaded seat is provided with an external thread that is compatible with the sewage plug.

[0010] Furthermore, a gasket and a sealing pad are provided between the sewage drain plug and the threaded seat.

[0011] Furthermore, the filter element is provided with a plurality of filter holes on the outer surface of one end close to the threaded seat.

[0012] Furthermore, the loosening torque of the sewage plug is not less than 35 m·N.

[0013] Furthermore, the scale-inhibiting pipe body is provided with a through hole along the axial direction.

[0014] Furthermore, the diameter of the through hole is 2.5-3.0 mm.

[0015] Furthermore, there is a gap between the scale-inhibiting tube body and the inner wall of the filter element.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model discloses a slow-release scale-inhibiting tube, comprising a filter element and a scale-inhibiting tube body. A plurality of scale-inhibiting tube bodies are arranged in the filter element. The scale-inhibiting tube body is formed by sintering ultra-high molecular weight PE and a scale inhibitor. The scale inhibitor is wrapped in the ultra-high molecular weight PE, so that it can be continuously slow-released outwards, and the scale inhibitor will not be released quickly, thereby achieving the purpose of continuous scale inhibition, which is beneficial to prolonging the service life of the scale-inhibiting tube body. The scale inhibitor has no effect on water quality, which is beneficial to maintaining the characteristics of raw water. At the same time, by designing a detachable sewage plug, the sewage plug can be directly removed and the scale-inhibiting tube body can be drawn out, so that impurities between the scale-inhibiting tube body and the inner wall of the filter element can be quickly cleaned. The operation is convenient and efficient, the overall structure is simple, the cost is low, and it is suitable for industrial promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS
