Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipeline construction equipment, and particularly relates to a cleaning device for PE pipeline interfaces. Background Art
[0002] PE pipes are pipes made of polyethylene (PE), with a wide range of applications and various characteristics. They have many excellent properties. For example, good temperature resistance: PE pipes can be used in the range of -75°C to 40°C, and the low-temperature embrittlement temperature is very low, which is suitable for installation and construction in winter. Strong corrosion resistance: Polyethylene is an inert material, which can resist the erosion of various chemical media, without the need for anti-corrosion protection, and will not occur rot, rust, and corrosion. Good flexibility: The elongation at break exceeds 800%, and local vibration will not cause the vibration of all pipes, with strong earthquake resistance, etc.
[0003] When different PE pipes are connected, generally welding, hot melt connection and other methods are used. Before butt joint connection, the joint surface needs to be cleaned and polished to achieve good connection and avoid affecting the connection due to impurities, etc. After connection, there will still be weld scars or burrs at the interface of the PE pipe, and the burrs inside the pipe need to be polished to avoid problems such as the formation of debris hooking and accumulation in the long-term use process, especially in sewage pipes.
[0004] In the prior art, the existing cleaning methods mainly use manual operation of scrapers, files, etc. to polish them. On the one hand, it is impossible to effectively clean the burrs inside the pipe. On the other hand, manual operation has low efficiency and high labor intensity. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a cleaning device for PE pipeline interfaces, which can effectively improve the efficiency of removing burrs, weld scars, etc. through an improved cleaning structure.

A slag suction pipeline is also arranged inside the pipe body, and a slag outlet is arranged at the tail end of the pipe body. The slag outlet is communicated with the slag suction pipeline, and the slag outlet is arranged perpendicular to the driving motor.
[0008] Further, a suction fan is connected to the slag outlet.
[0009] Further, the pipe body includes an outer pipe and an inner pipe, and the output shaft is arranged inside the inner pipe.

[0027] Such as Figures 1 - 3As shown in the figure, a cleaning device for PE pipe interfaces includes a pipe body 1, a driving motor 3 arranged at the tail end of the pipe body 1, and a grinding mechanism arranged at the front end of the pipe body 1. The output end of the driving motor 3 is connected with an output shaft through a coupling. The output shaft is arranged in the middle of the pipe body 1 and connected to the grinding mechanism. A slag suction pipeline 7 is also arranged in the pipe body 1, and a slag outlet 2 is arranged at the tail end of the pipe body 1. The slag outlet 2 is communicated with the slag suction pipeline 7, and the slag outlet 2 is arranged perpendicular to the driving motor 3.
[0028] Compared with the prior art, in the prior art, there are various connection methods between PE pipes. Mechanical structure connection methods can be adopted. For example, flange connection is mainly used for the connection between PE pipes and metal pipes or auxiliary equipment such as valves, flow meters, and pressure gauges. It mainly consists of a polyethylene flange connector, a steel or aluminum backpressure loose flange, a steel or aluminum flange plate, a gasket or sealing ring, bolts, nuts, etc. By tightening the bolts and nuts, the flange connector and the flange plate are in close contact, thus realizing the connection of the pipeline. Other methods such as hot melt connection and welding can also be used. Hot melt connection is one of the most commonly used and firm methods for PE pipe connection. It uses a special heating tool to heat the connection parts of the pipe or pipe fitting until they are melted. Then, the heating tool is removed and pressure is applied to closely connect the two melted surfaces together until the joint cools and solidifies. However, through hot melt connection and welding methods, on the one hand, it is necessary to grind the interfaces of PE pipes before hot melting and welding to remove burrs and the like at the interfaces of PE pipes to improve the docking effect. After hot melting, there will inevitably be some weld scars or burrs on the inner and outer walls of PE pipes. When used as a sewage pipe, larger weld scars or burrs may cause problems such as the hook and accumulation of dirt and sundries. After hot melting, it is also necessary to polish and clean the interfaces again.
[0029] In the present utility model, a grinding mechanism is arranged at the end of the pipe body 1. On the one hand, it can be used for grinding the connection end face of PE pipes, and on the other hand, it can directly extend into the PE pipe to polish and clean the interfaces of PE pipes again after hot melting to reduce burrs and the like at the interfaces of PE pipes. And the present utility model is also provided with a slag suction pipeline 7. By connecting a negative pressure fan later, it can also carry out the cleaning work of debris after grinding in the PE pipe to avoid debris residue.
[0030] The slag outlet 2 is connected with a suction fan. Through the suction fan, the sundries in the pipeline can be effectively sucked and cleaned, avoiding a large amount of construction sundries remaining in pipelines such as gas pipelines.
[0031] The pipe body 1 includes an outer pipe 8 and an inner pipe 4, and the output shaft is arranged inside the inner pipe 4. The slag suction pipeline 7 is arranged between the outer pipe 8 and the inner pipe 4. A bearing adapted to the output shaft is arranged at the end of the inner pipe 4. The inner pipe 4 is used to place the rotating motor output shaft, and a slag suction pipeline 7 is formed between the inner pipe 4 and the outer appearance, which can be used to clean sundries after connecting to a negative pressure fan.
[0032] The grinding mechanism includes a rotating bracket 5 connected to the output shaft and grinding blades 6 arranged on the rotating bracket 5. The output shaft is driven to rotate by the motor, so as to drive the rotating bracket 5 to rotate and use the grinding blades 6 on the rotating bracket 5 to perform grinding operations. The overall operation is simple and easy to implement.
[0033] During specific use, first, before the hot melting operation, it is necessary to perform a grinding operation on the connecting end face of the PE pipe to avoid excessive burrs at the interface affecting the hot melting effect. During this process, turn on the driving motor 3 to drive the grinding mechanism to work, and slowly approach the interface of the PE pipe with one side of the grinding blade 6. Of course, it is also possible to use a cutter to re-cut a smooth hot-melting surface at the interface to be connected for both PE pipes to be hot-melted. After the butt hot melting is completed, the pipe body 1 can be inserted into the PE pipe, and the grinding blade 6 at the end of the pipe body 1 is used to perform a re-grinding operation on the interface after hot melting. And after the grinding operation is completed, the driving motor 3 can be turned off, and a negative pressure fan can be connected to the slag outlet 2 to suck and clean the sundries generated in the PE pipe. The residue in the overall pipeline is less.
[0034] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
