Description
Technical Field
[0001] The utility model relates to the technical field of automatic pipeline cleaning, in particular to an automatic pipeline cleaning device adopting a suction method. Background Art
[0002] Pipelines are widely used in the fields of tap water, electricity, steel, petroleum, chemical industry, paper making, printing, pure water, etc. due to their good shock absorption, protection, compensation, expansion and other functions, and have now become indispensable necessary accessories in these fields. However, in the prior art, during the use of pipelines, automatic cleaning is usually not achievable, and the accumulation of dirt and debris over a long time affects the service life of the pipelines. In the prior art, the cleaning of pipelines requires separate flushing and cleaning by relying on unloading equipment, with low efficiency. At the same time, in fields with poor working environments such as iron and steel smelting and rare earth smelting, where the working process requires continuity, disassembly is even more impossible. And long-term deposition also causes the pipeline to gradually become narrower or even blocked, resulting in abnormal operation.
[0003] In order to solve the above problems, the purpose of the utility model is to provide an automatic pipeline cleaning and suction device, which solves the problems of deposition and blockage caused by the inability to clean the inner wall of pipeline equipment in real time during the processes of iron and steel smelting and rare earth smelting, and realizes the automatic cleaning technology without disassembly, improves work efficiency, and reduces production costs. Content of the Utility Model
[0004] In order to achieve the above functions, the technical solution adopted by the utility model is:
[0005] An automatic pipeline cleaning and suction device includes a piston pushing device; the automatic pipeline cleaning and suction device includes two or more pipelines, at least one end of the pipeline is connected to a collection container, and at least one pipeline is connected to a temporary storage container; a piston is provided inside the pipeline; a connection space is provided between the two or more pipelines.
[0006] There are different connection methods between the pipelines, such as:
[0007] Connection method one, the pipelines are cross-connected, and a connection space is formed at the intersection well at the cross-section.
[0008] Connection method two, the pipelines are arranged side by side or obliquely without intersection or in different directions, and a common connection space is provided between different pipelines.
[0009] Connection method three, the pipelines are arranged obliquely, and the tops of the pipelines meet at the intersection, forming a connection space.
[0010] The connection space is an independent component, and the connection space and the pipeline are an integral structure; or, the connection space and the pipeline are detachably connected.
[0011] The connection space is a triangular, quadrilateral, polygonal, elliptical, or irregularly shaped three-dimensional cavity.
[0012] The connection space is placed at the upper end of the pipeline, or the connection space is placed in the middle of the pipeline, dividing the pipeline into two sections and / or multiple sections.
[0013] The temporary storage container has the following structures:
[0014] Structure 1, the temporary storage container is an independent container, and the connection between the container opening and the end of the connected pipeline is rotationally connected or snap-connected through a sealed switch. After the connection combination, the end of the pipeline includes the temporary storage container; or the temporary storage container includes the end of the pipeline.
[0015] There is a spacing between the container opening of the temporary storage container and the sealed switch.
[0016] Structure 2, the temporary storage container and the pipeline are an integral structure, and a sealed switch is provided at the bottom of the temporary storage container.
[0017] An instant heating component is provided outside the pipeline and / or outside the temporary storage container.
[0018] A hollowed-out structure baffle is provided at the end of the pipeline.
[0019] The piston has different shapes and structures such as a cone, a cylinder, a prism, an olive shape, etc.
[0020] The inner diameter of the end of the pipeline is smaller than the inner diameter of other parts of the pipeline; the inner diameter of the end of the pipeline is slightly smaller than the inner diameter of the top and the middle by 2 - 5 mm; and it is smaller than the diameter of the widest part of the piston.
[0021] The pipeline automatic cleaning and suction device further includes a vacuum pump, and the vacuum pump is connected to at least one upper end of the pipeline and / or the connection space between the vacuum pump and the pipeline.
[0022] The beneficial effects of the present utility model are:
[0023] Provided is a pipeline automatic cleaning and suction device. The connection space enables substances to flow between different pipelines. Through the control of a piston or a vacuum pump, substances such as the melt and powder in the collection container can be sucked through the pipeline to the connection space, then transported to the temporary storage container, and finally the molten metal is poured out through the temporary storage container for use. Thus, it replaces the manual or robotic operation in the steel smelting and rare earth smelting processes to place the empty collection container during electrolysis and pour the container filled with molten metal after electrolysis, realizing the automation and intelligence of the collection of substances such as melt and powder in the collection container.
[0024] The piston is arranged inside the pipeline, and in combination with the piston pushing device, the piston is controlled to push towards the end of the pipeline. During the pushing process, the residues adhering to the inner wall of the pipeline are discharged from the outlet at the end of the pipeline, and real-time cleaning management avoids the occurrence of pipeline blockage. There is an instantaneous heating component outside the pipeline to maintain the pipeline temperature, which can further prevent the melt from sticking to the inner wall of the pipeline and is beneficial to the removal of the molten metal adhering to the wall. According to the operation requirements, a temporary storage container is provided at the end of the pipeline. The temporary storage container forms a sealed state with the end of the pipeline, and the air pressure inside different pipelines can be controlled according to the operation requirements, thereby controlling the conveying path of the melt.
[0025] There is a certain distance between the edge of the outlet of the temporary storage container and the airtight switch; or there is a certain distance between the end of the pipeline connecting the temporary storage container and the airtight switch. When the melt is poured out obliquely from the temporary storage container, if there is a little melt sticking to the edge of the opening of the temporary storage container, due to the distance between the outlet and the sealing component, it will not affect the sealing performance of the connection between the two.
[0026] The piston structure is designed into a shape and structure such as a cone or an olive with a thick middle and thin ends, or the inner diameter of the pipeline is designed to gradually and uniformly become smaller from the top to the end. In this way, there is no need to design the hollow baffle at the end of the pipeline. When the piston is pushed to the end of the pipeline, since the middle is thick, it blocks the end of the pipeline. Or when a circular, cylindrical or other piston is pushed to the end of the pipeline, since the inner diameter of the end of the pipeline is smaller than the inner diameter of the top, the piston is blocked when it is pushed to the end of the pipeline. The design of this structure not only reduces the material and labor costs of the hollow baffle at the end of the pipeline, but also avoids the blockage of the hollow of the baffle, which affects the cleaning effect inside the pipeline.

[0049] Embodiment 1:
[0050] Such as Figure 1As shown in the figure, the present utility model relates to an automatic pipeline cleaning and suction device, which is applied to an automatic rare earth smelting device in the rare earth smelting field. The automatic pipeline cleaning and suction device is made of materials such as rhenium, molybdenum, and niobium with high temperature resistance, high strength, good wear resistance, and corrosion resistance. It includes pipelines 1 and 2 with an inner diameter of 20 - 100 mm. Pipeline 1 and pipeline 2 are cross - connected, and a connection space 3 is formed at the intersection well. The end of pipeline 1 is connected to a collection container 4, and the end of pipeline 2 is connected to a temporary storage container 5. There is an integrally formed structure between pipeline 2 and the temporary storage container 5, and a sealed switch 7 is provided at the bottom of the temporary storage container 5. Pistons 6 are respectively arranged in the inner cavities of pipelines 1 and 2, and there is also a piston pushing device. The width of the piston 6 matches the diameter of the pipeline. A hollowed - out baffle 11 is provided at the bottom of the inner cavities of pipelines 1 and 2. A vacuum pump 9 with adjustable air pressure is installed at the top of pipeline 1 to adjust the air pressure inside the pipeline; the top of pipeline 2 is in a closed state.
[0051] When the automatic pipeline cleaning and suction device is performing the suction work, the pistons 6 of pipelines 1 and 2 move above the connection space 3, and the air pressure inside the pipeline is controlled at a negative pressure of 40 - 70 kPa through the vacuum pump 9. The substances (generally molten liquid or powder) in the collection container 4 are sucked into pipeline 1 from the end of pipeline 1 and transported to the connection space 3. At this time, the substances in the connection space 3, due to their own gravity, are transported from pipeline 2 to the temporary storage container 5 for temporary storage. When the molten liquid in the temporary storage container 5 has been stored for a certain time or a certain amount, it is poured out from the sealed switch 7.
[0052] During the transportation of substances, the substances are likely to adhere to the inner walls of pipelines 1 and 2 to form residues. Prolonged use will cause the inner diameter of the pipeline to become smaller and blockage to occur. Replacing the pipeline will affect the working efficiency of the device on the one hand, and on the other hand, it will also cause waste of the pipeline and an increase in production costs. At this time, the piston is pushed by the piston pushing device to move the piston 6 in the pipeline downward to the hollowed - out baffle 11 and stop; during the movement of the piston 6, the residual molten liquid adhering to the inner wall of the pipeline is discharged downward from the pipeline, keeping the inside of the pipeline clean.
[0053] When the pipeline automatic cleaning and suction device is in the cleaning state, at least one of pipeline 1 and pipeline 2 is connected to a cylinder piston pushing device. The cylinder piston pushing device at least includes a piston rod connected to the piston and a cylinder. The cylinder provides power for the pushing of the piston, and controls the movement direction and speed of the piston through the magnitude of the power. During normal cleaning work, power is provided by the cylinder to control the piston to push towards the end of the pipeline at a speed of 0.1 - 1 m / s. During the pushing process, the residues adhering to the inner wall of the pipeline are discharged from the outlet at the end of the pipeline. In the case of more residues or a small amount of accumulation, the power provided by the cylinder is increased by adjustment, so that the piston is quickly pushed out towards the end of the pipeline to increase the impact force, thereby removing a large amount of or accumulated residues in the pipeline. Through the piston pushing device, the molten liquid adhering to the inner wall of the pipeline during the transmission of the molten metal is discharged from the outlet at the end of the pipeline, and real-time cleaning management is carried out to avoid the phenomenon of pipeline blockage. An instantaneous heating component is provided outside the pipeline to maintain the pipeline temperature, which can further prevent the molten liquid from adhering to the inner wall of the pipeline and is beneficial to the removal of the metal molten liquid adhering to the wall.
[0054] As Figure 2 shown, the temporary storage container 5 of the pipeline automatic cleaning and suction device is a part of pipeline 2 (the part below the connection space 3). A closed switch 7 is arranged at the lower end of pipeline 2, which is opened when pouring out objects and closed during storage.
[0055] As Figure 3 shown, based on the above structure and principle, the pipeline automatic cleaning and suction device may not include a vacuum pump 9, and the top end of pipeline 1 is also in a closed state. The width of the piston 6 in the pipeline conforms to the inner diameter of the pipeline. The movement of the piston 6 in the pipeline is controlled by existing technologies such as numerical control or the piston pushing device. The magnitude of the air pressure is adjusted through the movement of the piston 6 in the pipeline, thereby controlling the transportation of the molten liquid and the automatic cleaning of the pipeline. That is: when the piston 6 moves towards the lower end of the pipeline, the residual molten liquid on the inner wall of the pipeline is discharged downward in the pipeline to keep the pipeline clean. Then the piston 6 returns to the top end of the pipeline. During the return process, the airflow drives the objects (such as molten liquid) in the collection container 4 to be sucked into pipeline 1 through the end of pipeline 1 and transported to the connection space 3 and then to the temporary storage container 5 for temporary storage.
[0056] The piston structure is designed to be thinner at the lower end and thicker at the upper end. The lower end of the pipeline may not need to be designed with a hollow baffle at the end of the pipeline. When the piston is pushed to the end of the pipeline, the thinner end of the piston is pushed out of the pipeline, thereby pushing out the residues on the inner wall of the pipeline; since the upper end of the piston is thicker, it gets stuck when pushed to the end of the pipeline, preventing foreign objects from entering the pipeline. The design of this structure not only reduces the material and labor costs of the hollow baffle at the end of the pipeline, but also avoids the blockage of the hollow baffle and affects the cleaning effect inside the pipeline.
[0057] Embodiment 2:
[0058] AsFigure 4 , Figure 5 As shown, based on the structure and principle of the first embodiment, pipeline 1 and pipeline 2 are cross - combined, and the placement direction of pipeline 2 can also be vertical. During operation, when the objects in the collection container 4 are pumped into pipeline 1 through the end of pipeline 1 and transported to the connection space 3, due to the action of gravity, the objects in the connection space 3 fall into pipeline 2 more quickly and efficiently and are transported to the temporary storage container 5 for temporary storage.
[0059] Instant heating components 8 using electromagnetic induction heating are respectively provided outside the lower pipes of pipeline 1 and pipeline 2 (below the connection space 3). When using electromagnetic induction heating, an alternating magnetic field is generated by the components of the electronic circuit board. When an iron - containing container is placed on it, the surface of the container cuts the alternating magnetic lines of force, and an alternating current (i.e., eddy current) is generated in the metal part at the bottom of the container. The eddy current makes the iron atoms at the bottom of the container move at high speed and randomly, and the atoms collide and rub against each other to generate heat energy, thus achieving the heating effect. The instant heating components are provided outside the pipeline, which can further prevent the molten liquid from sticking to the inner wall of the pipeline and keep the inner wall of the pipeline clean.
[0060] The temporary storage container 5 of this second embodiment is an independent component, and the airtight switch 7 is placed at the combination of pipeline 2 and the temporary storage container 5. The temporary storage container 5 and pipeline 2 are detachably connected through the airtight switch 7. When the molten liquid in the temporary storage container 5 needs to be poured out after being stored for a certain time or a certain amount, the airtight switch 7 is opened, the temporary storage container 5 is removed for pouring, and then it is connected through the airtight switch 7. When the pipeline and the temporary storage container 5 are of the same size, the temporarily storage container 5 filled with molten liquid can also be removed, and another empty temporary storage container 5 is prepared to be connected to pipeline 2 to achieve uninterrupted operation. After the temporary storage container 5 and pipeline 2 are connected and combined, the edge of the outlet of the temporary storage container 5 includes the end of pipeline 2 (as Figure 4 shown), or the end of the pipeline 2 includes the outlet of the temporary storage container 5 (as Figure 5 shown).
[0061] Meanwhile, there is a certain distance 10 between the edge of the outlet of the temporary storage container 5 and the airtight switch 7; or there is a certain distance 10 between the end of the pipeline connecting the temporary storage container 5 and the airtight switch 7. When the molten liquid is poured out obliquely from the temporary storage container, if there is a little molten liquid sticking to the edge of the opening of the temporary storage container, due to the distance 10 between the outlet and the sealing component, it will not affect the sealing performance of the connection between the two.
[0062] Embodiment Three:
[0063] Based on the structure and principle of the first and second embodiments, pipeline 1 and pipeline 2 are respectively inclined in different directions, and their tops meet to form a connection space 3. The vacuum pump 9 is placed above the connection space (as Figure 6 shown).
[0064] When the pipeline automatic cleaning and suction device performs pipeline cleaning work (such as Figure 6 shown), the piston pushing device pushes the piston 6 to the hollow baffle 11 at the end of the pipeline. During the movement of the piston 6, the residual molten liquid adhering to the inner wall of the pipeline is discharged downward along the pipeline, keeping the inside of the pipeline clean. Then, the piston 6 is controlled by the piston pushing device to move to the top of the pipeline (such as Figure 7 shown), and the objects in the collection container 4 are sucked into the pipeline 1 through the end of the pipeline 1, transported to the connection space 3, and then transported to the temporary storage container 5 for temporary storage.
[0065] Embodiment 4:
[0066] As Figure 8 shown, on the basis of the structures and principles of Embodiments 1, 2, and 3, the pipelines 1 and 2 are arranged in parallel, and are connected and communicated with each other through the connection space 3. The vacuum pump 9 is placed outside the pipelines and is respectively connected to the tops of the pipelines 1 and 2 through connecting pipes.
[0067] The vacuum pump in this embodiment can also be connected to only pipeline 1 or pipeline 2, and the top of the non-connected pipeline is in a closed state. At the same time, the number of pipelines can be increased according to the requirements of work efficiency or site conditions, such as 3 pipelines or 4 pipelines working simultaneously. When multiple pipelines work simultaneously, only 1 pipeline can be connected to the collection container, and the other pipelines are connected to the temporary storage container; or both the connection to the collection container and the connection to the temporary storage container can be set as multiple pipelines. The arrangement of multiple pipelines can also be adjusted according to different requirements, such as: parallel arrangement, inclined arrangement, inverted Y-shaped arrangement, etc.
[0068] On the basis of Embodiments 1, 2, 3, and 4, in order to increase the capacity of the connection space 3, or due to special process requirements, the shape of the connection space 3 can be designed, such as designing the connection space 3 as a triangular, quadrilateral, polygonal, elliptical, or other irregular-shaped three-dimensional cavity. The piston can also be designed in the shape of a cone, a sphere, a cylinder, a prism, an olive, etc. Even the inner diameter of the pipeline can be designed such that the inner diameter at the end of the pipeline is smaller than that at the top, middle, etc. of the pipeline, and is also smaller than the widest diameter of the corresponding piston. As Figure 9 shown, the piston is designed as an olive shape with a thick middle and thin ends or a cone structure with a single thin end. At this time, there is no need to design the hollow baffle 11 at the end of the pipeline. When the piston is pushed to the end of the pipeline, the thin end of the piston is pushed out of the pipeline, and the thick middle part blocks the end of the pipeline. At this time, the residues in the pipeline are completely discharged, and the piston is blocked when it is pushed to the end of the pipeline. This solution not only reduces the material and labor costs of the hollow baffle at the end of the pipeline, but also avoids the blockage of the hollow of the baffle, which affects the cleaning effect inside the pipeline.
[0069] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it. For example, in terms of the application field, the present invention can also be applied to fields such as iron and steel smelting, petroleum, chemical industry, and papermaking. Although the present invention 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 described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
