Description

Technical Field

[0001] The utility model provides a weather-resistant and environment-friendly PPR pipe, belonging to the technical field of PPR pipes. Background Art

[0002] PPR is the abbreviation of tripropylene glycol. PPR pipe is also called random copolymer polypropylene pipe. It has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, simple construction and maintenance, and long service life. PPR pipe is widely used in construction, municipal, industrial and agricultural fields. PPR pipe is made of random copolymer polypropylene through extrusion into pipes and injection molding into pipe fittings.

[0003] The existing PPR pipe can basically meet the use needs, but there are still some defects: when the liquid medium flows from the water inlet of the PPR pipe to the water outlet of the PPR pipe body, it is often difficult to filter the liquid medium, and if a single filter is directly added for filtering, impurities will inevitably block the mesh of the filter, thereby affecting the normal circulation of the liquid medium in the PPR pipe. Based on this, the utility model provides a weather-resistant and environmentally friendly PPR pipe. Utility Model Content

[0004] The technical problem solved by the utility model is that it is difficult to filter the liquid medium, and if a single filter screen is directly added for filtering, impurities will clog the mesh of the filter screen, affecting the normal circulation of the liquid medium in the PPR pipe.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a weather-resistant and environmentally friendly PPR pipe, including a PPR pipe body, a filter screen is provided between the inner and outer walls of the PPR pipe body, the center of the filter screen is rotatably connected to a support rod, one end of the support rod is provided with a spiral rod, and the other end of the support rod is provided with a cleaning brush for cleaning the filter screen, and the bottom wall of the PPR pipe body is provided with a plugging head placed on the side of the filter screen close to the cleaning brush.

[0006] Furthermore, the PPR pipe body includes a PPR base layer, the inner wall of the PPR base layer is provided with an antibacterial hydrophobic layer, and the outer wall of the PPR base layer is coated with a weather-resistant coating layer.

[0007] Furthermore, the filter screen and the support rod are rotatably connected via a bearing.

[0008] Furthermore, the spiral rod is arranged at an end of the support rod away from the water inlet of the PPR pipe body, the cleaning brush is arranged at an end of the support rod close to the water inlet of the PPR pipe body, and the spiral rod is provided with spiral leaves.

[0009] Furthermore, the antibacterial hydrophobic layer is a film made of PE material, and nano silver ion antibacterial agent is arranged inside the PE material.

[0010] Furthermore, the thickness of the PPR base layer is 3-6 mm.

[0011] Furthermore, the bottom wall of the PPR pipe body is provided with a plugging hole threadedly connected to the plugging head.

[0012] Furthermore, the cleaning brush is provided with a brush strip that fits with the side wall of the filter.

[0013] Beneficial effects of the utility model:

[0014] The filter can filter the liquid medium, so that the impurities mixed in the liquid medium are retained on one side of the filter. By removing the plugging head, the impurities retained on one side of the filter can be discharged from the plugging hole. When the flowing liquid medium passes through the spiral rod, the flowing liquid medium can flow along the spiral blades, and then exert force on the spiral blades, so that the spiral blades can rotate, and then drive the spiral rod to rotate. Under the action of the bearing, the support rod is driven to rotate, and then the cleaning brush is driven to rotate around the support rod. The brush bars of the cleaning brush can clean out the impurities blocked in the mesh of the filter to prevent the impurities from clogging the mesh of the filter and affecting the normal circulation of the liquid medium in the PPR pipe body.
