Description

Technical Field

[0001] This utility model relates to the field of environmental waste treatment technology, and in particular to a rotatable suction pipeline for vacuum suction of landfill leachate. Background Technology

[0002] In the field of landfill leachate treatment, vacuum suction systems are the core devices for efficient leachate transfer, but their suction pipelines have long faced multiple technical bottlenecks. Existing suction pipelines mostly employ fixed rigid pipe bodies or simple flexible joint designs, which have the following shortcomings: traditional pipelines lack rotational freedom after connection, making them prone to twisting and bending when the suction equipment is moved or its angle adjusted, leading to interruption of negative pressure transmission, increased pipeline wear, and even equipment failure; existing sealing structures (such as rubber gaskets and O-rings) are prone to leakage in high vacuum environments due to aging of seals and gaps between connections, reducing suction efficiency; traditional pipelines mostly use threaded connections or simple snap-fit ​​designs, which cannot meet the needs of rapid assembly and disassembly, and improper sequence of sealing surface removal during disassembly can cause momentary leakage, affecting the stability of the vacuum environment of the suction target. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rotatable suction pipeline for landfill leachate vacuum suction, which achieves 360° non-tangling rotational docking while meeting high sealing requirements and easy disassembly and assembly requirements.

[0004] The purpose of this utility model is achieved as follows: A rotatable and dockable vacuum suction pipeline for landfill leachate includes a rotatable docking joint and a flexible telescopic suction pipeline. The rotatable docking joint includes a fixed end flange, a rotating bushing, and a magnetic fluid sealing assembly. The fixed end flange is fixedly connected to an external suction device. The end of the rotating bushing is rotatably engaged with the fixed end flange through a precision copper sleeve. The magnetic fluid sealing assembly is installed on the mating surface between the rotating bushing and the fixed end flange, forming a double sealing structure. The flexible telescopic suction pipeline includes a quick docking connector, a flexible telescopic tube, and a connecting clamp. The quick docking connector is locked to one end of the flexible telescopic tube through the connecting clamp, and the other end of the flexible telescopic tube is locked to the end of the rotating bushing through the connecting clamp.

[0005] In use, this invention first connects the fixed flange of the rotatable connector to the external pumping equipment to ensure the overall pipeline is connected to the pumping system. Then, by rotating the rotating sleeve, the orientation of the flexible telescopic suction pipeline is adjusted to accommodate leachate sources at different locations. One end of the flexible telescopic pipeline is locked to the end of the rotating sleeve via a connecting clamp, and the other end is fixed to the quick-connect connector via the connecting clamp. Operators can easily connect the quick-connect connector to the leachate collection point or treatment device. After starting the pumping equipment, the leachate is drawn in through the flexible telescopic pipe and enters the pumping equipment through the internal channel of the rotating sleeve and the fixed flange. If the suction direction needs to be adjusted, simply rotate the sleeve to change the angle. The magnetic fluid sealing assembly ensures no leakage during rotation and stable negative pressure transmission.

[0006] Compared with existing technologies, the advantages of this utility model are as follows: the rotatable design of the rotating bushing, combined with the telescopic characteristics of the flexible telescopic tube, allows for adjustment of the suction angle and distance without moving the pumping equipment, avoiding pipe twisting and kinking, and adapting to the dynamic suction needs of leachate in complex sites; the dual sealing structure of the magnetic fluid sealing component and the precision copper sleeve effectively isolates leachate leakage, ensuring vacuum suction efficiency and equipment operation safety; the combination of quick-connect couplings and connecting clamps enables rapid assembly and disassembly, shortening pipeline deployment time and improving maintenance efficiency; the coordinated design of the rigid fixed end and the flexible pipeline balances support strength and deformation adaptability, extending the service life of the pipeline.

[0007] As a further improvement of this utility model, the inner wall of the flexible telescopic tube is smooth and resistant to acid and alkali corrosion.

[0008] As a further improvement of this utility model, both the rotatable docking joint and the flexible telescopic suction pipeline are made of corrosion-resistant materials.

[0009] As a further improvement of this utility model, the flexible telescopic tube is made of stainless steel.

[0010] As a further improvement of this utility model, the outer circumference of the rotating bushing is provided with an installation groove, and the installation groove and the inner wall of the fixed end flange form a cavity for accommodating the magnetohydrodynamic sealing assembly.

[0011] As a further improvement of this utility model, the end of the rotating bushing is inserted into the sleeve cavity of the fixed end flange, and the precision copper sleeve is located between the inner wall of the sleeve cavity and the outer wall of the rotating bushing.

[0012] As a further improvement of this utility model, the end face of the fixed end flange is fixedly connected to the end face of the connecting flange of the external equipment by bolts. Attached Figure Description

[0020] like Figure 1-4The illustration shows a rotatable suction pipeline for landfill leachate vacuum suction, comprising a rotatable connector 1 and a flexible telescopic suction pipeline 2. The rotatable connector 1 includes a fixed end flange 101, a rotating sleeve 102, and a magnetic fluid sealing assembly 103. The end face of the fixed end flange 101 is fixedly connected to the end face of a connecting flange 3 of an external device by bolts. The end of the rotating sleeve 102 is rotatably engaged with the fixed end flange 101 by a precision copper sleeve 104, i.e., the end of the rotating sleeve 102 is inserted into the sleeve cavity of the fixed end flange 101. The precision copper sleeve 104 is located between the inner wall of the sleeve cavity and the outer wall of the rotating sleeve 102. The magnetic fluid sealing assembly 103 is installed on the rotating end flange 101. The sleeve 102 and the fixed end flange 101 form a double sealing structure. Specifically, the outer circumference of the rotating sleeve 102 is provided with an installation groove 102a.

The other end of the flexible telescopic tube 202 is locked to the end of the rotating sleeve 102 by the heavy-duty connecting clamp 203. The inner wall of the flexible telescopic tube 202 is smooth and resistant to acid and alkali corrosion.

[0021] Both the rotatable docking joint 1 and the flexible telescopic suction line 2 are made of corrosion-resistant materials, such as stainless steel.

[0022] The magnetohydrodynamic sealing assembly 103, as a key sealing unit, consists of a magnetic conductor, pole shoes, and magnetic fluid (which can be set as a single or multiple sets according to the sealing level requirements). It is installed on the mating surface between the rotating bushing 102 and the fixed end flange 101, and together with the precision copper sleeve 104, it forms a double sealing structure, which not only ensures the stability of the vacuum during rotation, but also prevents leakage of leachate.

[0023] The advantages of this utility model are as follows: the rotating bushing 102 achieves flexible steering through the rotational engagement of the precision copper sleeve 104 and the fixed end flange 101; the flexible telescopic tube 202 covers suction points at different distances by utilizing its deformation capability; the two work together to dynamically adjust the suction angle and coverage range without moving the suction equipment, adapting to the multi-point suction needs of complex sites; the magnetic fluid sealing assembly 103 and the precision copper sleeve 104 form a double sealing structure, with a sealing leakage rate ≤10%. -6 Pa·m³ / s, pipeline vacuum tolerance up to -0.1MPa, ensuring stable vacuum during rotation and preventing leachate leakage; supports compatibility with leachate pumping equipment of various diameters, with strong versatility.
