Description

Technical Field

[0001] This utility model belongs to the field of silicon single crystal production technology, and in particular relates to a pipeline feeding and receiving device and a filtration device. Background Technology

[0002] In the photovoltaic industry, the production of monocrystalline silicon rods requires extremely stringent cleanliness standards for the production environment. Therefore, various tools and equipment are used in the production process to achieve cleaning. Filter tanks, as one of the main and commonly used tools, utilize negative pressure gas flow connected to a dry pump to adsorb impurities such as oxides and volatiles, thereby improving cleaning efficiency. While frequently used, the exposed gas supply pipes pose a risk of wear and tear, and their considerable length makes them difficult to manage properly, potentially creating safety hazards on the production site. Summary of the Invention

[0003] In view of the above problems, the present invention provides a pipeline winding and unwinding device and a filtration device to solve the above or other problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pipe take-up and release device, including a pipe take-up component and a limiting component. The pipe take-up component is configured to be rotatable for taking up and releasing the pipe. The limiting component includes a movable limiting part, which is used to engage with a first engaging part on the pipe, so that the pipe is limited to the length corresponding to the first engaging part. The first engaging part is any one of a plurality of engaging parts arranged sequentially along the axial length of the pipe.

[0005] Furthermore, the pipe receiving assembly includes a container for winding the pipe and a reset member connected to the container. The container is configured to rotate under the restoring force of the reset member.

[0006] Furthermore, the container has a spiral track on its circumferential side, the pipe is coiled on the spiral track, and the reset component is a spiral spring.

[0007] Furthermore, the pipeline deployment and retraction device also includes an installation component, which has a channel structure for passing through the pipeline, and a limiting component is located at the channel structure.

[0008] Furthermore, the limiting component includes a plug and a limiting elastic member. The plug is movably connected to the mounting component, and the limiting elastic member is located between the plug and the mounting component. At least a portion of the plug is used to engage with the first engaging portion on the pipeline under the restoring force of the limiting elastic member.

[0009] Furthermore, the pipeline deployment and retraction device also includes an unlocking component, which is connected to the limiting component and drives the limiting component to move, causing the limiting component to disengage from the first engaging component and releasing the limiting component from restricting the pipeline.

[0010] Furthermore, the unlocking component includes a pressing member and an axial positioning member connected to the pressing member. The pressing member drives the axial positioning member to move, and the axial positioning member performs axial movement and rotation to position itself in the axial direction. By positioning the axial positioning member in different axial positions, the limiting member can be engaged with the first latching part or disengaged from the first latching part.

[0011] Furthermore, the pipeline deployment and retraction device also includes a locking component, which includes a locking body and a locking groove provided on the locking body. The locking body is used to be fitted onto the pipeline, and the locking groove is provided on the side of the locking body opposite to the pipeline along the circumferential direction. Each locking component cooperates with the pipeline to form a locking part.

[0012] Furthermore, the pipeline is a corrugated pipe, and the corrugated structure on the corrugated pipe forms an interlocking part.

[0013] A filtration device includes a filter tank, two pipes, and pipe retraction and extension devices as described above located at both ends of the filter tank along its axial direction. The two pipes are respectively connected to the air inlet and air outlet of the filter tank, and each pipe is engaged with its corresponding pipe retraction and extension device.

[0014] By adopting the above technical solution, pipe retraction and release devices are set at both ends of the filter tank along the axial direction. The pipe retraction and release devices respectively store the air inlet pipe and the air outlet pipe of the filter tank. At the same time, the pipe retraction and release devices can retract and release the pipes, avoiding the air inlet pipe and the air outlet pipe of the filter tank from being exposed to the production site, avoiding the irregular accumulation of the air inlet pipe and the air outlet pipe on the production site, reducing the wear and tear caused by friction aging due to irregular accumulation of the air inlet pipe and the air outlet pipe on the production site, avoiding entanglement and accumulation, reducing the risk of wear and aging, improving the service life of the air inlet pipe and the air outlet pipe, facilitating the standardized management of the air inlet pipe and the air outlet pipe, and reducing the safety risks at the production site.

[0015] The pipe take-up and release device is equipped with a pipe take-up assembly, which is rotatable and allows the pipe to be coiled around it for storage. The pipe can also be coiled around a container on the take-up assembly, which is rotatable and will not interfere with the pipe take-up and release actions. The container is equipped with a reset component, which automatically performs the pipe take-up action under the restoring force of the reset component.

[0016] The system is equipped with a limiting component and an unlocking component, which work together. The limiting component restricts the extension of the pipeline, which has multiple engaging parts. A limiting component is located at the pipeline extension point of the mounting component, and it connects with the engaging parts to apply resistance to the pipeline, limiting its extension length to meet usage requirements. When retracting the pipeline, the unlocking component drives the limiting component to disengage from the engaging parts. The pipeline can then be wound around the container under the reverse rotation of the retracting component, thus retracting the pipeline. The limiting and unlocking components control the extension length of the pipeline and enable automatic retracting, simplifying pipeline retracting and unwinding operations and improving work efficiency.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Figures 1-5 The diagram shows a structural schematic of an embodiment of the present invention. This embodiment relates to a pipeline retraction device and a filter device. The pipeline retraction device can realize the retraction and retraction of pipelines. Pipeline retraction devices are respectively provided at both ends of the filter tank along the axial direction. The air inlet pipeline and air outlet pipeline of the filter device are housed on the corresponding pipeline retraction devices, which avoids the air inlet pipeline and air outlet pipeline being exposed to the outside of the filter tank and irregularly piled up on the production site after the filter tank is used, and reduces the wear and tear of the air inlet pipeline and air outlet pipeline of the filter tank caused by friction and aging.

[0034] A pipe retraction device 1, such as Figure 2 As shown, it includes a pipe receiving assembly 11 and a limiting assembly connected to the pipe. The pipe receiving assembly 11 is rotatable and is used for winding the pipe and for winding and unwinding the pipe by rotating. The pipe can be wound around the pipe receiving assembly 11. By applying a pulling force to the pipe, the pipe receiving assembly 11 is rotated, thereby extending the pipe out of the pipe winding and unwinding device 1 to realize unwinding. During the winding process, the pipe receiving assembly 11 rotates in the opposite direction to wind the pipe around the pipe receiving assembly 11, and the pipe receiving assembly 11 stores the pipe.

[0035] After the pipe is laid out, the limiting component is activated to limit the length of the pipe. That is, during the pipe laying process, when the pipe extends beyond the required length of the pipe laying device 1, the limiting component is activated to restrict the reverse movement of the pipe (opposite to the extension movement direction), so that the pipe cannot move in the opposite direction and the pipe is limited to the extension length (layout length) to meet the subsequent use requirements.

[0036] When the pipe needs to be retracted, the limiting component is driven to move, so that the limiting component releases the restriction on the pipe. The pipe can move in the opposite direction (opposite to the direction of extension) under the rotation of the retracting component 11. The pipe is wrapped around the retracting component 11 for retraction.

[0037] In use, the pipe retraction device 1 allows the pipe retraction assembly 11 to rotate under external force. Simultaneously, the retraction assembly 11 can return to its original rotation direction under its own restoring force (opposite to the direction of rotation under external force). The pipe is wound around the retraction assembly 11, with one end extending out of the pipe retraction device 1 and located outside of it, for gripping the pipe and facilitating connection to other equipment. When the pipe is needed, a pulling force is applied to extend it out of the pipe retraction device. In step 1, the process of extending the pipe beyond the required length of the pipe extension / retraction device 1 involves the following steps: First, the pipe extends beyond the required length. Then, the limiting component activates, applying resistance to the pipe and confining it to that position, maintaining the extended length. Second, when the pipe is no longer needed and needs to be retracted, the limiting component is activated, releasing the resistance and allowing the pipe to wrap around the retraction component 11 under its own reverse rotation. The pipe then retracts back into the pipe extension / retraction device 1, completing the pipe retraction process. The pipe extension / retraction device 1 allows for the storage of pipes when not in use, preventing irregular accumulation of pipes on the production site, reducing wear and tear due to friction and aging, and extending the pipe's service life.

[0038] Specifically, such as Figure 2 and 4 As shown, in order to enable the limiting component to apply resistance to the pipeline and limit the extension length of the pipeline, the limiting component includes a movable limiting part 13. The limiting part 13 is used to engage with a first engaging part on the pipeline, so that the pipeline is limited to the length corresponding to the first engaging part. The first engaging part is any one of a plurality of engaging parts arranged sequentially along the axial length of the pipeline. That is, during the pipeline laying process, the limiting part 13 can selectively engage with any engaging part at any position on the pipeline. Different engaging parts at different positions correspond to different pipeline laying lengths. When the pipeline laying length is determined, the limiting part 13 limits the pipeline laying length and restricts the pipeline to that length.

[0039] The aforementioned engaging portion has a slot 120 structure to allow the limiting component 13 to engage with the engaging portion. One configuration of the engaging portion is as follows: the pipe deployment / retraction device further includes engaging components 12, each engaging component 12 cooperating with the pipe to form an engaging portion. Multiple engaging components 12 are sequentially arranged along the axial direction of the pipe, forming multiple engaging portions along the axial direction of the pipe. In this configuration, the pipe can be a corrugated pipe, a PVC pipe (plain pipe, without corrugations), or other pipe structures; the pipe structure is not limited. All engaging components 12 cooperate with the limiting component 13. The multiple engaging components 12 are sequentially arranged along the axial direction of the pipe, and the limiting component 13 is located on the path of pipe movement. The limiting component 13 engages with engaging components 12 at different positions, thus limiting the pipe to different lengths. The multiple engaging components 12 can display the length of the pipe extending from the pipe retraction device 1. Different positions of the engaging components 12 indicate different lengths of the pipe, making it easy for the user to understand the extension length of the pipe. The limiting component 13 is inserted and engaged with the engaging components 12 at different positions to restrict the pipe to different length positions. At the same time, the engaging components 12 protect the pipe and prevent damage to the pipe caused by direct insertion of the limiting component 13 into the pipe. The material hardness of the engaging components 12 is greater than that of the pipe, which enhances the strength of the pipe and also provides support for the limiting component 13, preventing the limiting component 13 from jamming when it releases its restraint on the pipe due to the flexibility of the pipe.

[0040] like Figure 4As shown, the aforementioned engaging component 12 includes an engaging body and a plurality of slots 120 disposed on the engaging body. The engaging body is sleeved on the pipeline, and the slots 120 are disposed along the circumferential direction of the engaging body. The plurality of slots 120 are disposed sequentially along the axial direction of the pipeline on the side of the engaging body opposite to the pipeline. The arrangement of the slots 120 facilitates the insertion of the limiting component 13 into the slot 120, so that the limiting component 13 and the engaging component 12 are engaged and mated. The locking body is a tube structure with openings at both ends, allowing it to be fitted onto the pipe. The cross-sectional shape of the locking body is adapted to the cross-sectional shape of the pipe, ensuring a tight fit between the inner wall of the locking body and the outer wall of the pipe when the locking body is fitted. To prevent the locking body from moving along the axial direction of the pipe due to the thrust of the limiting component 13 when the locking groove 120 is inserted into the limiting component 13, the limiting component 13 effectively limits the pipe. The locking component 12 is fixedly connected to the pipe. The locking body can be bonded to the pipe, or the inner surface of the locking body can be threaded, and the location of the locking component 12 on the pipe can be provided with external threads, allowing the locking body to be threadedly connected to the pipe. Alternatively, the locking body can be fixedly connected to the pipe using tape, screws, or other fixed connection methods. The fixed connection method between the locking component 12 and the pipe is selected and set according to actual needs, and no specific requirements are specified here.

[0041] Multiple engaging components 12 can be arranged at equal intervals along the axial direction of the pipeline, or they can be arranged at non-equal intervals along the axial direction of the pipeline, or other arrangements, depending on actual needs. No specific requirements are specified here. In some feasible embodiments, preferably, multiple engaging components 12 are arranged at equal intervals along the axial direction of the pipeline. The distance between two adjacent engaging components 12 is selected and set according to actual needs. Based on the number of engaging components 12 extending from the pipeline, the length of the pipeline extending from the pipeline retraction device 1 can be determined, and the length of the pipeline extending from the pipeline retraction device 1 can be controlled.

[0042] The axial length of the engaging body can be selected according to actual needs, but it must be ensured that the number of multiple slots 120 on the engaging body is sufficient to cooperate with the limiting component 13. The number of slots 120 can be selected and set according to actual needs, and no specific requirements are made here. The shape of the part of the limiting component 13 that contacts the slot 120 is adapted to the cross-sectional shape of the slot 120 so that the free end of the limiting component 13 can be inserted into the slot 120.

[0043] Alternatively, another structure of the locking part is as follows: the pipeline is a corrugated pipe, and the corrugated structure on the corrugated pipe forms the locking part. The corrugated structure of the corrugated pipe has a rectangular waveform, and there is a locking groove 120 between two adjacent rectangular corrugated structures. The limiting component 13 is inserted and engaged with the locking groove 120 to realize the limiting component 13 to limit the pipeline. In this structure, the corrugated pipe can be a 50mm PE corrugated pipe.

[0044] To facilitate the installation of the pipe receiving assembly 11 and the limiting component 13, the pipe receiving and discharging device 1 also includes a mounting component 10. The mounting component 10 has a channel structure for the pipe to pass through, and the limiting component 13 is located at the channel structure of the mounting component 10. In some feasible embodiments, the mounting component 10 is a shell structure with an internal space. The internal space facilitates the installation of the pipe receiving assembly 11 and also facilitates the storage of the pipe. After the pipe is wound around the pipe receiving assembly 11, it is located inside the mounting component 10, preventing irregular accumulation of pipes on the production site and causing frictional aging. The mounting component 10 can be a cylindrical structure with an internal space, and its cross-sectional shape can be circular, polygonal, or elliptical. Alternatively, the mounting component 10 can be a spherical structure with an internal space, or other shell structures with internal spaces. The choice and setting are based on actual needs, and no specific requirements are specified here.

[0045] To facilitate the installation of the tube receiving assembly 11 and the limiting component 13, in some feasible embodiments, the mounting component 10 is preferably a cylindrical structure with an internal space.

[0046] To facilitate the routing of the pipeline around the pipe receiving assembly 11, at least two channel structures are provided on the peripheral side of the mounting member 10. One channel structure is used for the extension of the pipeline, and the other channel structure is used for the insertion of the pipeline. That is, both ends of the pipeline are located outside the mounting member 10. One end of the pipeline enters the interior of the mounting member 10 through one channel structure and is routed around the pipe receiving assembly 11. Then, the other end of the pipeline extends out from the other channel structure of the mounting member 10. The mounting member 10 and the pipe receiving assembly 11 realize the storage of the pipeline without interfering with the use of the pipeline. Both ends of the pipeline are used in conjunction with other equipment, such as the filter tank 2 and the dry pump.

[0047] A limiting component 13 is provided at a channel structure for pipe extension in the mounting component 10 to control the length of the pipe extending out of the mounting component 10. The limiting component 13 can be inserted and engaged with any engaging component 12 on the pipe.

[0048] The aforementioned channel structure has a certain length, and both axial ends of the channel structure are open structures. One end of the channel structure is connected to the interior of the mounting component 10, and the other end of the channel structure is connected to the exterior of the mounting component 10, so that the pipeline can pass through the channel structure to enter or exit the mounting component 10.

[0049] like Figure 2 and 3 As shown, the above-mentioned pipe receiving assembly 11 includes a container 110 for winding the pipe and a reset member 111 connected to the container 110. The container 110 is configured to rotate under the action of external force. After the external force disappears, the container 110 is reset under the action of the reset member 111. The pipe can be wound around the container 110. The container 110 holds and stores the pipe. The reset member 111 provides the container 110 with the force of its rotation during the pipe receiving process, so as to realize the automatic pipe receiving action of the pipe receiving assembly 11. When the pipe is being released, the pipe-receiving assembly 11 stretches the pipe, and the pipe applies a force to the container 110, causing the container 110 to rotate and extend the pipe out of the mounting member 10. When the pipe is being retracted, the external force applied to the pipe disappears, and under the restoring force of the reset member 111, the container 110 rotates in the opposite direction (opposite to the rotation direction of the container 110 when the pipe is extended), so that the pipe is wrapped around the container 110 under the rotation of the container 110, and the pipe is retracted.

[0050] The aforementioned container 110 is a cylindrical structure, and its cross-sectional shape is preferably circular to reduce bending deformation of the pipeline after it is wrapped around the container 110, thereby extending the service life of the pipeline. The container 110 has a certain length in the axial direction so that pipelines of different lengths can be wrapped around it. That is, the container 110 can accommodate pipelines of different lengths. The axial length of the container 110 can be selected and set according to actual needs, and no specific requirements are made here. The axial length and radial dimension of the container 110 can be selected and set according to the dimensions of the mounting component 10 so that the container 110 can be rotatably installed in the mounting component 10.

[0051] To allow the container 110 to rotate freely within the mounting component 10, fixed shafts are provided at both axial ends of the container 110. These fixed shafts are coaxial with the container 110 and are rotatably connected to the inner wall of the mounting component 10 via bearings. This allows the container 110 to rotate relative to the mounting component 10, enabling the pipe-receiving and releasing actions. When the container 110 is installed within the mounting component 10, it can be positioned along the axial direction of the mounting component 10 or along the radial direction. The specific arrangement of the container 110 within the mounting component 10 is selected based on actual needs and is not specified here.

[0052] To facilitate the winding of pipes onto the container 110, a spiral track 112 is provided on the container 110. The pipe is wound around the spiral track 112, which is spirally arranged along the axial direction of the container 110. The spiral track 112 has a groove structure with a certain depth, allowing the pipe to be placed inside the spiral track 112 and spirally wound along the axial direction of the container 110 and the length direction of the spiral track 112. The depth of the groove structure of the spiral track 112 is not less than the diameter of the pipe, so that the pipe can be wound on the spiral track 112 in one or more layers, allowing the container 110 to accommodate pipes of different lengths.

[0053] Of course, the spiral track 112 can also be a groove structure composed of two parallel baffles. The two parallel baffles are spirally arranged along the axial direction of the container 110. The baffles are fixedly connected to the circumferential side of the container 110. The fixed connection method can be fixed by screws or other connectors, welding, integral molding, or other fixed connection methods. The specific requirements are not specified here.

[0054] To facilitate the winding of the pipe onto the spiral track 112, the inlet and outlet portions of the spiral track 112 are arranged along the radial direction of the container 110, so that the pipe can be easily and quickly wound onto the spiral track 112.

[0055] The aforementioned reset element 111 is a spiral spring. The inner end of the spiral spring is connected to a fixed shaft at one end of the container 110, and the outer end of the spiral spring is connected to the outer periphery of the end face of one axial end of the container 110. A fixing rod and a fixing pin are provided on the outer periphery of the end face of the container 110. The outer end of the spiral spring is connected to the fixing rod or the fixing pin. Through the restoring force of the spiral spring, the container 110 rotates in the opposite direction after the external force disappears, thus resetting. The number of reset elements 111 is at least one. When there is only one reset element 111, it is located at either axial end of the container 110. When there are two reset elements 111, they are respectively located at the two axial ends of the container 110.

[0056] The aforementioned limiting component 13 includes a plug-in 130 and a limiting elastic member 131 connected to the plug-in 130. The plug-in 130 is movably connected to the mounting member 10. The limiting elastic member 131 is located between the plug-in 130 and the mounting member 10. At least a portion of the plug-in 130 is used to engage with the first engaging portion on the pipeline under the restoring force of the limiting elastic member 131. Specifically, the connector 130 is hinged to the inner wall of the mounting member 10. One end of the connector 130 is used to insert into the slot 120 of the engaging part. One end of the limiting elastic member 131 is connected to the inner wall of the mounting member 10, and the other end of the limiting elastic member 131 is connected to the connector 130. The limiting elastic member 131 is set to a compressed state so that the free end of the connector 130 can slide along the surface of the pipe during the extension process. When the pipe stops extending, the free end of the connector 130 can be inserted into the slot 120 of the corresponding engaging part. Under the action of the elastic force of the limiting elastic member 131, the free end of the connector 130 is pressed into the slot 120. When the pipe moves in the opposite direction (opposite to the extension movement direction), the connector 130 provides resistance to the pipe and fixes the pipe at the extension length.

[0057] The connector 130 has a rod-like structure. The shape of the free end of the connector 130 is adapted to the shape of the slot 120 so that the free end of the connector 130 can be inserted into the slot 120. The connector 130 is hinged to the inner wall of the mounting member 10. The connector 130 can rotate relative to the mounting member 10, and the connector 130 is inclined. The axis of the connector 130 intersects the axis of the pipeline so that when the pipeline moves in the opposite direction to the extension direction, the connector 130 can be used as a guide for the pipeline. It provides thrust along the extension direction of the pipe, restricts the movement of the pipe, and confines the pipe to the position of the extension length; the partial connection between the limiting elastic member 131 and the free end of the plug 130 and the hinge with the mounting member 10 avoids interference between the insertion action of the limiting elastic member 131 and the free end of the plug 130, and at the same time can provide thrust to the plug 130 along the radial direction of the pipe, so that the free end of the plug 130 is always in contact with the pipe during the extension of the pipe.

[0058] In some feasible embodiments, the aforementioned limiting elastic element 131 is preferably a spring.

[0059] When the pipeline is no longer in use and needs to be retracted, the limiting component 13 needs to disengage from the engaging part, allowing the pipeline to move in the opposite direction to its extension. Therefore, the pipeline retraction device is also equipped with an unlocking component 14, which is connected to the limiting component 13 and drives the limiting component 13 to move away from the engaging part 12, thus releasing the limitation on the pipeline's movement. Specifically, the other end of the connector 130 is hinged to the unlocking component 14. When the unlocking component 14 is activated, it drives the connector 130 to swing along the hinge point with the mounting part 10, causing the end of the connector 130 to disengage from the slot 120, thus releasing the limitation imposed by the connector 130 on the pipeline.

[0060] Specifically, such as Figure 2 and 5 As shown, the unlocking component 14 includes a pressing member 140 and an axial positioning member connected to the pressing member 140. The pressing member 140 drives the axial positioning member to move, and the axial positioning member performs axial movement and rotation to position the axial position. Through the positioning of the axial positioning member at different axial positions, the connector 130 can be inserted and engaged with the slot 120 or the connector 130 can be disengaged from the slot 120.

[0061] The aforementioned axial positioning component includes a guide 141, a rotating component 142 that cooperates with the pressing component 140, a driving component 143 connected to the rotating component 142, and an elastic component 144 disposed on the driving component 143. The guide 141 is disposed on the mounting component 10 and is coaxially arranged with the pressing component 140. A portion of the pressing component 140 is disposed inside the guide 141, and one end of the pressing component 140 extends out of the guide 141 and is located outside the guide 141 to facilitate positioning of the pressing component 140. When pressure is applied, the pressing member 140 can move along the axial direction of the guide member 141. Pressing the pressing member 140 drives the rotating member 142 to move along the axial direction of the guide member 141. Through the cooperation between the guide member 141 and the rotating member 142, the driving member 143 moves relative to the guide member 141 and is fixed in the moved position. The driving member 143 is connected to the limiting member 13. The driving member 143 drives the limiting member 13 to move, and the limiting member 13 releases the restriction on the movement of the pipeline.

[0062] A through hole is formed in the housing of the mounting component 10. The guide component 141 passes through the through hole and is fixed in the through hole. The two axial ends of the guide component 141 extend out of the two sides of the housing of the mounting component 10, that is, one end of the guide component 141 is located outside the housing of the mounting component 10 and protrudes from the outer side of the housing of the mounting component 10, and the other end of the guide component 141 is located inside the housing of the mounting component 10 and protrudes from the inner side of the housing of the mounting component 10. The guide component 141 can be fixedly connected to the housing of the mounting component 10 by threads, or the guide component 141 can be welded to the housing of the mounting component 10, or other fixed connection methods can be used. The specific requirements are not specified here.

[0063] The aforementioned guide member 141 is a tube structure with openings at both ends. Multiple guide grooves 1410 are provided on the circumferential side of the guide member 141. The multiple guide grooves 1410 are arranged evenly in sequence along the circumferential direction of the guide member 141. In order to avoid interference between the guide member 141 and the mounting member 10 caused by the arrangement of the guide grooves 1410, the axial length of the guide groove 1410 along the guide member 141 is less than the axial length of the guide member 141. The guide groove 1410 is located on the part of the guide member 141 located inside the mounting member 10. The guide groove 1410 is formed by the end of the guide member 141 located inside the mounting member 10 recessed along the axial direction of the guide member 141 toward the other end of the guide member 141. The guide groove 1410 penetrates the side wall of the guide member 141 and penetrates the end of the guide member 141 located inside the mounting member 10. That is, the interior and exterior of the guide member 141 are connected through the guide groove 1410. Along the axial direction of the guide member 141, one end of the guide groove 1410 is connected to the exterior, that is, this end of the guide groove 1410 is an open structure.

[0064] Along the circumferential direction of the guide member 141, two connected inclined structures are provided between two adjacent guide grooves 1410. One end of one inclined structure is fixedly connected to the end of one side of the opening end of one guide groove 1410, and the other end of the inclined structure is connected to one end of another inclined structure. The other end of the other inclined structure is fixedly connected to the end of one side of the opening end of another guide groove 1410. That is, a groove is provided between the relatively close two sides of two adjacent guide grooves 1410. The groove is used to contact and cooperate with the rotating member 142 to limit the axial and circumferential movement of the rotating member 142 along the guide member 141.

[0065] In the two inclined plane structures, one end of the first inclined plane structure is fixedly connected to the end of one side of the opening end of a guide groove 1410. The other end of the inclined plane structure extends a certain length along the first direction and along the first circumferential direction of the guide member 141 to form the inclined plane structure. The extension length is selected according to actual needs. The other end of the first inclined plane structure is connected to one end of the second inclined plane structure through a transition plane structure. The end of the second inclined plane structure extends a certain length along the first direction and along the first circumferential direction of the guide member 141, so that the other end of the second inclined plane structure is fixedly connected to the end of one side of the opening end of another guide groove 1410 to form the inclined plane structure. Here, when the first inclined plane structure extends, the first direction is the direction from the unopened end to the open end of the guide groove 1410, and the first circumferential direction of the guide member 141 is the direction from the first guide groove 1410 to the second guide groove 1410.

[0066] The aforementioned transition plane structure is arranged along the axial direction of the guide member 141. Along the direction from the unopened end to the open end of the guide groove 1410, the first end of the transition plane structure is connected to the second inclined structure, and the second end of the transition plane structure is connected to the first inclined structure. The connection between the transition plane structure and the second inclined structure forms the aforementioned groove structure that contacts and engages with the rotating member 142.

[0067] The aforementioned pressing member 140 is a tubular structure. The pressing member 140 is coaxially arranged with the guide member 141, and a portion of the pressing member 140 is located inside the guide member 141. The pressing member 140 can move relative to the guide member 141, and one end of the pressing member 140 extends out of the guide member 141. The pressing member 140 is coaxially arranged with the rotating member 142, and the pressing member 140 is located at one end of the rotating member 142. The other end of the pressing member 140 is in contact with the rotating member 142. When pressure is applied to the end of the pressing member 140 away from the end in contact with the rotating member 142, the pressing member 140 can move along the axial direction of the guide member 141. The pressing member 140 applies a force to the rotating member 142, causing the rotating member 142 to move with the pressing member 140. The rotating member 142 is in contact with the guide member 141, limiting the pressing member 140 to the pressed position.

[0068] The aforementioned rotating component 142 is a cylindrical structure. The rotating component 142 includes a rotating body and a plurality of guide bars 1420 disposed on the peripheral side of the rotating body. The plurality of guide bars 1420 are evenly arranged along the circumferential direction of the rotating body. The number of guide bars 1420 is consistent with the number of guide grooves 1410 on the guide component 141. Before pressure is applied to the pressing component 140, the rotating component 142 is inserted into the guide component 141, and each guide bar 1420 is inserted into the corresponding guide groove 1410. One end of the guide bar 1420 facing the pressing member 140 protrudes from the end of the rotating body, and this end of the guide bar 1420 is a beveled structure. The inclination direction of this end of the guide bar 1420 is the same as the inclination direction of the beveled structure at the end of the guide member 141, so that when the beveled structure at the end of the guide bar 1420 contacts the beveled structure at the end of the guide member 141, they are in surface-to-surface contact. When the rotating member 142 rotates, the beveled structure at the end of the guide bar 1420 moves along the surface of the beveled structure at the end of the guide member 141.

[0069] To allow the rotating component 142 to be inserted into the guide component 141 and the guide strip 1420 to slide within the guide groove 1410, the outer diameter of the rotating body is adapted to the inner diameter of the guide component 141, and the thickness of the guide strip 1420 is adapted to the thickness of the guide component 141. When the rotating body is located within the guide component 141, the guide strip 1420 is located within the guide groove 1410. A limiting component is provided at the end of the rotating body away from the contact with the pressing component 140. The limiting component is annular and coaxially arranged with the rotating body. The inner diameter of the limiting component is fixedly connected to the outer peripheral side of the rotating body, and the outer diameter of the limiting component is adapted to the outer diameter of the guide component 141. This ensures that when the rotating component 142 moves within the guide component 141 along the axial direction, the limiting component contacts the end of the guide component 141, preventing the rotating component 142 from completely entering the guide component 141. The limiting component restricts the axial movement of the rotating component 142 along the guide component 141.

[0070] The aforementioned driving member 143 is a rod structure. One end of the driving member 143 is inserted into the rotating member 142, and the rotating member 142 can rotate relative to the driving member 143. The other end of the driving member 143 is hinged to the end of the plug-in member 130 away from the pipe. When the rotating member 142 moves, it drives the driving member 143 to move along the axial direction of the guide member 141. The driving member 143 applies a force to the plug-in member 130, causing the plug-in member 130 to swing. The end of the plug-in member 130 that is in contact with the pipe separates from the pipe, thereby releasing the restriction on the pipe positioning. The end of the rotating body with the limiting member is an open structure. One end of the driving member 143 can be inserted into the rotating body through this open structure to achieve a plug-in connection between the driving member 143 and the rotating body. The driving member 143 and the rotating body are in clearance fit so that the rotating member 142 can rotate relative to the driving member 143. The other end of the rotating member 142 is a closed structure so that the pressing member 140 can contact and engage with the rotating member 142.

[0071] An elastic element 144 is sleeved on the driving element 143, and the elastic element 144 provides a restoring force for the reset of the driving element 143. The elastic element 144 is preferably a spring. A blocking part 146 is provided on the driving element 143. The blocking part 146 is an annular plate structure. The blocking part 146 is arranged along the radial direction of the driving element 143. The inner diameter of the blocking part 146 is fixedly connected to the outer peripheral side of the driving element 143. The outer diameter of the blocking part 146 is adapted to the outer diameter of the guide 141. The elastic element 144 is located between the blocking part 146 and the end away from the one that is inserted into the rotating element 142.

[0072] To facilitate the installation of the unlocking component 14, the unlocking component 14 also includes a fixing member 145. The fixing member 145 is a tubular structure, with one end of the fixing member 145 fixedly connected to the inner wall of the mounting member 10. The fixing member 145 and the guide member 141 are coaxially arranged, and the inner diameter of the fixing member 145 is adapted to the outer diameter of the guide member 141. That is, the fixing member 145 and the guide member 141 are plugged into each other. Both the fixing member 145 and the guide member 141 are fixedly connected to the mounting member 10. The through holes on the mounting member 10 at the locations of the fixing member 145 and the guide member 141 are coaxially arranged. The portion of the guide member 141 located inside the mounting member 10 is inserted into the fixing member 145. The rotating member 142 and the drive... Both component 143 and elastic component 144 are located inside the fixed component 145. The rotating component 142 and the driving component 143 are coaxially arranged with the fixed component 145. The free end of the fixed component 145 is an open structure. The opening size of the free end of the fixed component 145 is adapted to the size of the driving component 143. The free end of the fixed component 145 is provided with a stop part of an annular plate structure. The outer diameter side of the stop part is fixedly connected to the inner circumferential side of the fixed component 145. The inner diameter size of the stop part is adapted to the outer diameter size of the driving component 143. The driving component 143 can extend out of the fixed component 145 through the inner diameter hole of the stop part and extend to the outside of the fixed component 145 so that this end of the driving component 143 can be connected to the plug-in component 130. The elastic element 144 on the drive member 143 is located between the abutment part of the fixing member 145 and the blocking part 146 on the drive member 143. When the drive member 143 moves along the axial direction of the guide member 141, it can compress the elastic element 144. At the same time, after the external force disappears, the drive member 143 can move along the axial direction of the guide member 141 to reset under the action of the restoring force of the elastic element 144.

[0073] When the unlocking component 14 unlocks the connector 130, it applies pressure to the pressing component 140. The pressing component 140 moves along the axial direction of the guide component 141 towards the driving component 143 (for ease of description, this direction of movement is set downwards). The pressing component 140 drives the rotating component 142 to also move downwards along the axial direction of the guide component 141. The guide bar 1420 slides within the guide groove 1410. When the guide bar 1420 has completely moved out of the guide groove 1410, the tip of the beveled structure at the end of the guide bar 1420 and the tip of the adjacent beveled structure at the end of the guide component 141 (for ease of description, set as follows: The inclined structure of the guide member 141 is the first inclined structure 1412, and the other inclined structure of the guide member 141 is the second inclined structure 1411. During this process, when the rotating member 142 is driven to move downward along the axial direction of the guide member 141, the driving member 143 moves with the movement of the rotating member 142. The driving member 143 moves towards the insertion member 130, compressing the elastic member 144. The driving member 143 applies pressure to the insertion member 130, causing the insertion member 130 to swing. The end of the insertion member 130 that is inserted into the slot 120 disengages from the slot 120, and the insertion member 130 applies pressure to the pipeline. The force disappears, and the pipeline moves under the restoring force of the reset member 111 of the pipe-receiving assembly 11, winding around the container 110 to achieve pipe retraction; simultaneously, the pressure on the pressing member 140 is removed, and the driving member 143 moves in the opposite direction under the restoring force of the elastic member 144. The driving member 143 drives the rotating member 142 to move closer to the guide member 141, and the tip of the first inclined structure 1412 applies a component force along the circumferential direction of the rotating member 142 to the tip of the inclined structure of the guide bar 1420, causing the rotating member 142 to rotate, and the inclined structure of the guide bar 1420 moves along the first... The end face of the inclined structure 1412 slides until the tip of the inclined structure of the guide bar 1420 is located in the groove between the first inclined structure 1412 and the second inclined structure 1411. The inclined structure of the guide bar 1420 is blocked by the transition plane structure, and the rotating member 142 stops rotating, so that the driving member 143 remains in the state of extending out of the fixing member 145 and retracts the tube. That is, during the tube retraction process, after the force applied to the pressing member 140 is removed, the rotating member 142 engages with the guide member 141, the driving member 143 remains in the state of extending out of the fixing member 145, and the plug-in member 130 remains in the state of being separated from the slot 120.

[0074] After the tube is retracted, pressure is applied to the pressing member 140 again. The pressing member 140 exerts a force on the rotating member 142, causing the rotating member 142 to move (downward) along the axial direction of the guide member 141 towards the driving member 143. The tip of the inclined structure of the guide bar 1420 contacts the tip at the intersection of the second inclined structure 1411 and the transition plane structure of the guide member 141. The rotating member 142 drives the driving member 143 to move in the same direction along the axial direction of the guide member 141, compressing the elastic member 144. At this time, the pressure applied to the pressing member 140 is removed. Under the restoring force of the elastic member 144, the driving member 143 moves in the opposite direction, driving the rotating member 142 to move in the opposite direction (towards the guide member 141). The tip at the intersection of the second inclined structure 1411 and the transition plane structure exerts a force on the tip of the inclined structure of the guide bar 1420 along the circumferential direction of the rotating member 142. The rotating member 142 rotates again under the force (the two rotations of the rotating member 142 are in the same direction, both from the first inclined structure 1412 to the second inclined structure 1411). The inclined structure of the guide bar 1420 slides along the surface of the second inclined structure 1411. When the guide bar 1420 moves to the opening of the guide groove 1410, under the restoring force of the elastic member 144, the guide bar 1420 enters the guide groove 1410 and slides in the guide groove 1410. The rotating member 142 moves towards the pressing member 140 along the axial direction of the guide member 141, and drives the pressing member 140 to move along the same direction until the blocking part 146 of the rotating member 142 contacts the end of the guide member 141. The rotating member 142 stops moving. At this time, the driving member 143 also moves a certain distance along the same direction, causing the plug-in member 130 to swing in the opposite direction. The plug-in member 130 contacts the engaging member 12 again to facilitate the subsequent tube placement operation.

[0075] A filtration device, such as Figure 1As shown, it includes a filter tank 2, two pipes, and pipe retraction / discharge devices 1 as described above located at both ends of the filter tank 2 along its axial direction. The two pipes are respectively connected to the air inlet and air outlet of the filter tank 2. The two pipes are respectively matched with their respective pipe retraction / discharge devices 1. Each pipe retraction / discharge device 1 retracts or releases the corresponding pipe. The two pipes mentioned above are the inlet pipe 3 and the outlet pipe 4, respectively. The inlet pipe 3 is connected to the inlet of the filter canister 2, and the outlet pipe 4 is connected to the outlet of the filter canister 2. Pipe retraction devices 1 are provided at both ends of the filter canister 2 along its axial direction to store the inlet pipe 3 and the outlet pipe 4. When the filter canister 2 is not in operation, the inlet pipe 3 and the outlet pipe 4 are respectively stored in the corresponding pipe retraction devices 1. When the filter canister 2 is in operation, the pipe retraction devices 1 perform a pipe release action, so that the inlet pipe 3 and the outlet pipe 4 extend to the required length to meet the usage requirements of the filter canister 2. One end of the inlet pipe 3 is connected to the filter canister 2, and the inlet pipe 3 is wound around a pipe retraction device 1. The other end of the inlet pipe 3 extends out of the pipe retraction device 1, and the other end of the inlet pipe 3 is connected to the mounting component 10. One opening of the air inlet pipe 3 enters the mounting component 10 and coils around the container 110. After coiling, the other end of the air inlet pipe 3 extends out from another opening of the mounting component 10, so that external force can be applied to this end of the air inlet pipe 3 to release the air inlet pipe 3. Similarly, the air outlet pipe 4 is set in the same way. One end of the air outlet pipe 4 is connected to the filter tank 2. The air outlet pipe 3 is coiled inside another pipe retraction device 1. The other end of the air outlet pipe 3 extends out of another pipe retraction device 1. The other end of the air outlet pipe 4 enters the mounting component 10 through one opening on the mounting component 10 of the other pipe retraction device 1 and coils around the container 110. After coiling, the other end of the air outlet pipe 4 extends out from another opening of the mounting component 10, so that external force can be applied to this end of the air outlet pipe 4 to release the air outlet pipe 4.

[0076] When the pipeline take-up and drop device 1 is connected to the filter tank 2, the mounting part 10 is fixedly connected to the filter tank 2. The fixed connection method can be welding or fixed connection by bolts or other connecting parts. The fixed connection method can be selected according to actual needs, and no specific requirements are made here.

[0077] The aforementioned filter tank 2 is a tank structure. The air inlet pipe 3 of the filter tank 2 is connected to and communicates with the dry pump. When the dry pump is activated, it generates negative pressure, which causes gas flow. When the gas flows, it carries away impurities such as oxides and volatiles in the crystal pulling environment. The gas carrying oxides and volatiles enters the filter tank 2 along the air inlet pipe 3. When the gas flows in the filter tank 2, oxides and volatiles will adhere to the filter tank 2, thus achieving the filtration of oxides and volatiles. The filtered gas is discharged from the air outlet pipe.

[0078] Multiple engaging parts are provided on both the intake pipe 3 and the exhaust pipe 4. The arrangement of the multiple engaging parts on the intake pipe 3 and the exhaust pipe 4 is selected according to actual needs. Preferably, when the engaging part is a structure formed by the engaging component 12 and the pipe, the multiple engaging components 12 on the intake pipe 3 and the exhaust pipe 4 are arranged at equal intervals.

[0079] When in use, the filter device applies a pulling force to the intake pipe 3 according to the required length, pulling the intake pipe 3 out of the pipe retraction device 1. During the extension process (pipe retraction process), the container 110 rotates, the reset member 111 is compressed, and the end of the connector 130 that contacts the pipe remains in contact with the intake pipe 3, sliding along the axial direction of the intake pipe 3. When the intake pipe 3 reaches the required extension length, the pulling force on the intake pipe 3 is stopped, and the connector 130 is inserted into the corresponding locking member 12. The connector 130 is inserted into the locking groove 120, providing resistance to the reverse movement of the intake pipe 3 (the direction of pipe retraction), thus limiting the intake pipe 3 to that extension length. Similarly, the extension process of the exhaust pipe 4 is the same, and will not be described again here.

[0080] After the filter stops working, the inlet pipe 3 and outlet pipe 4 need to be stored. When storing the inlet pipe 3, pressure is applied to the unlocking component 14 of the pipe storage device 1 connected to the inlet pipe 3. The unlocking component 14 actuates and applies pressure to the connector 130. The connector 130 swings and separates from the locking component 12. At this time, the pressure can be released. The container 110 rotates in the opposite direction under the restoring force of the reset component 111. The inlet pipe 3 rotates with the container 110 and coils around the container 110 to achieve storage. After the inlet pipe 3 is stored, pressure is applied to the unlocking component 14 again. The unlocking component 14 applies pressure to the connector 130. The connector 130 swings and contacts the inlet pipe 3 again. After the pressure is released, the unlocking component 14 resets, and the connector 130 always remains in contact with the inlet pipe 3. The process of retracting the exhaust pipe 4 is the same, so it will not be described again here.

[0081] By adopting the above technical solution, pipe winding and unwinding devices are installed at both ends of the filter tank along its axial direction. These devices respectively house the inlet and outlet pipes of the filter tank. Simultaneously, the devices can both wind up and unwind pipes, preventing the inlet and outlet pipes from being exposed on the production site and avoiding irregular accumulation of these pipes. This reduces wear and tear caused by friction and aging due to irregular accumulation, prevents tangling and buildup, reduces the risk of wear and aging, extends the service life of the inlet and outlet pipes, facilitates standardized management of the pipes, and lowers safety risks on the production site. The pipe winding and unwinding device includes a rotating pipe winding assembly. The pipes can be coiled around the assembly for storage. The rotating assembly also prevents damage to the pipes. The infeed and outfeeding actions of the pipe cause interference. A reset component is installed on the container, and under the restoring force of the reset component, the pipe infeed action can be automatically realized. A limit component and an unlocking component are provided, which cooperate to limit the pipe. Multiple engaging parts are provided on the pipe, and a limit component is set at the pipe extension position of the mounting component. The limit component and engaging parts are inserted and connected, applying resistance to the pipe and limiting its extension length to meet the usage requirements. When the pipe is infeeding, the unlocking component drives the limit component to act, disengaging the limit component from the engaging parts. The pipe can then be wound around the container under the reverse rotation of the infeed component, realizing pipe infeed. The setting of the limit component and unlocking component can control the extension length of the pipe and automatically infeed, making the infeed and outfeeding operations simple and improving the efficiency of pipe infeeding and outfeeding.
