Description

TECHNICAL FIELD

[0001] The utility model belongs to pipeline installation and construction technical field in electromechanical installation engineering, and relates to a self-cleaning anti-blocking sewer device for grease sewage. BACKGROUND

[0002] With the increasing requirement of mechanical parts assembly to cleanliness, the use of part cleaning machine is becoming more and more popular. With it, there are more and more oil-containing industrial wastewater discharge conditions. At the same time, the requirement of sewage for kitchen sink and dishwasher and other equipment is increasing, and the oil content of kitchen sewage drainage in civil buildings is also increasing, and the kitchen sewage pipe blockage is becoming more and more common. Whether it is industrial or civil, the problem of grease blockage of sewage pipe caused by grease-containing sewage and the defect of inconvenient cleaning of pipe after blockage are becoming more and more prominent. At present, the main mode is "after-treatment measures", that is, after the pipe is blocked, various dredging methods are used.

[0003] The conventional method includes chemical dredging and physical dredging. Chemical dredging is to dissolve grease by using lye or pipeline dredging agent and other chemical reagents, so as to soften the blockage. This method needs a long reaction time, and the effect is not complete, there may be incomplete dredging, and it may have a certain corrosion effect on the sewage pipe. Physical dredging is to use hand-operated dredger, "one-shot dredger" and other equipment to make the blockage separate from the inner wall of the sewage pipe by mechanical stirring or pressure impact. This method is troublesome to operate, has low reliability, and the working environment is relatively poor (dirty and foul odor).

[0004] The above-mentioned main dredging methods all have the problems of incomplete effect, corrosion of pipeline, troublesome operation, low reliability and relatively poor working environment, so optimization and solution are urgently needed. CONTENT OF THE UTILITY MODEL

[0005] Therefore, the utility model aims at providing a self-cleaning anti-blocking sewer device for grease sewage, which can avoid the problem of sewage pipe blockage caused by grease-containing sewage discharge, and can realize rapid installation and disassembly, and is convenient for cleaning and inspection at any time

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A self-cleaning anti-blocking sewer device for grease sewage, comprising a water inlet pipe, a hose and a drain pipe connected in sequence by a socket and spigot quick connector and interference fit; an oil-repellent layer is arranged on the inner wall of the drain pipe, the oil-repellent layer is a SiO2 nano papilla structure; a steel wire framework for fixing the curved shape of the hose is wound on the outer wall of the hose, and a polytetrafluoroethylene oil-repellent layer is arranged on the inner wall of the hose.

[0008] Optionally, the nano particle diameter of the SiO2 nano papilla structure is 180-220 nm.

[0009] Optionally, the socket quick connector is a lead-free interface, an asbestos cement interface, an intumescent filler interface or a rubber ring interface.

[0010] Optionally, the water inlet pipe, the hose and the drain pipe are sequentially arranged from top to bottom.

[0011] Optionally, the drain pipe is embedded below the ground, and the end away from the hose is connected with a main sewage pipeline.

[0012] Optionally, the hose is an "S" type hose.

[0013] The utility model discloses the beneficial effect lies in:

[0014] The "S" type hose and the drain pipe are all provided with oil-repellent layers on the inner walls, wherein the oil-repellent layer provided on the inner wall of the drain pipe is an oil-repellent layer with SiO2 nano papilla structure, which lifts up water molecules and oil molecules by using the papilla structure to form excellent hydrophobic and oleophobic properties, thereby achieving "prevention" of pipeline blockage.

[0015] The water inlet pipe, the hose and the drain pipe are connected through the socket quick connector, and the connection mode adopts micro-interference fit, which forms a tight connection and is also beneficial to reducing assembly stress and part deformation; in addition, this connection mode is relatively easy to assemble, so that the water inlet pipe, the hose and the drain pipe can be quickly connected and disassembled, and "inspection during operation" can be conveniently realized.

[0016] The utility model fundamentally solves the root cause of grease blockage of the sewer pipeline by combining "prevention in advance" and "inspection during operation", and easily realizes daily cleaning and inspection of the system.

[0025] Please see Figure 1 This is a self-cleaning, anti-clogging drainage device for oily wastewater. It includes an inlet pipe 1, an "S"-shaped flexible hose 2, and a drain pipe 3, connected sequentially from top to bottom and interference-fitted by a quick-connect fitting 4. The inner wall of the drain pipe 3 is provided with an oleophobic layer, which is a SiO2 nanopapillary structure. The diameter of the SiO2 nanopapillary structure nanoparticles is 180–220 nm. The drain pipe 3 is pre-buried underground, with the end furthest from the flexible hose 2 connected to the main sewage pipe.

[0026] The quick-connector 4 is one of the following: lead alloy interface, asbestos cement interface, expansion filler interface, and rubber ring interface.

[0027] Water inlet pipe 1 is usually the drain pipe for cleaning equipment or kitchen sink. The pipe material and diameter are determined according to the equipment and sink parameters. This section is provided by the construction unit or owner.

[0028] The "S" type hose 2 adopts a steel wire Teflon hose 2, and a polytetrafluoroethylene oil-repellent layer is arranged on the inner wall, which has excellent oil-repellent and water-repellent and anti-corrosion performance, and grease will not adhere to the inner wall of the pipeline when passing through; the hose 2 is wrapped with a steel wire skeleton, so that the pipeline has good flexibility, which is beneficial to form an "S" type water seal.

[0029] The detachable socket and spigot quick connector 4 is arranged at both ends of the hose 2, the quick connector has a series of models, and can be matched with different pipe diameter interfaces; the water inlet pipe 1, the "S" type hose 2 and the drain pipe 3 are connected through the socket and spigot quick connector 4, and a socket and spigot connection mode with a micro interference fit is adopted. The micro interference fit refers to that there is a small interference between the parts, that is, the hole diameter of one part is slightly smaller than the shaft diameter of the other part. When assembled, the parts will produce a certain compression and extrusion effect, and form a tight connection. This connection mode is tightly connected, but not too tightly fastened, which is beneficial to reduce the assembly stress and part deformation; the assembly is relatively easy, and the processing precision of the parts is relatively low; and it is especially suitable for occasions that require a certain fastening force but do not want to produce too large stress. In the utility model, the socket and spigot connection adopts a micro interference fit, which can realize quick plug-in connection and convenient disassembly.

[0030] The drain pipe 3 is embedded in the floor (or floor), and is connected to a sewage drainage main pipe. The pipe body material adopts PVC, and an oil-repellent layer is coated on the inner wall of the PVC drain pipe 3. The oil-repellent layer adopts a nano structure (nanoparticles with a diameter of 180-220 nm, preferably 200 nm) SiO2 papillary structure, which lifts water molecules and oil molecules, and forms excellent water-repellent and oil-repellent performance.

[0031] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions, and all should be covered in the scope of the claims of the utility model.
