Description

Technical Field

[0001] This invention relates to the field of tubular chain machine cleaning technology, and more specifically to a cleaning system for a tubular chain machine. Background Technology

[0002] A tubular chain conveyor is a device that uses a chain as a traction tool to transport powdery, granular, or lumpy materials through a pipeline. The chain is built into the pipeline, and several scraper discs are spaced apart on the chain. A material conveying space is formed between adjacent scraper discs. The pipeline has feeding and discharging nodes. The material is conveyed from the feeding node to the discharging node by the traction of the chain. Tubular chain conveyors typically also include a tension box and a transmission box. A pair of conveying pipes connects the tension box and the transmission box. The chain is a closed chain, with both ends meshing with sprocket assemblies in the tension box and the transmission box, respectively.

[0003] In some special applications, it may be necessary to change the conveyed material. Therefore, the conveying pipes of the tubular chain conveyor must be cleaned before material change. Additionally, even without material change, the tubular chain conveyor may experience internal material adhesion and blockage after prolonged use, requiring cleaning and maintenance in the same manner.

[0004] However, existing tubular chain machines still have drawbacks such as high cleaning and maintenance difficulty and complicated cleaning operations. If a thorough cleaning of the tubular chain machine is required, it usually needs to be disassembled for cleaning, which results in a long cleaning and maintenance cycle.

[0005] Therefore, it is necessary to develop a tubular chain machine and related technologies that can avoid extensive disassembly, reduce cleaning and maintenance workload, and shorten cleaning and maintenance cycles to address the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention proposes a cleaning system for tubular chain conveyors, designed to facilitate the cleaning and maintenance of the conveying pipes. The specific technical solution is as follows: A cleaning system for a tubular chain conveyor includes a conveying pipe mounted on the conveying pipe, a feeding device and an automatic unloading device respectively mounted on the conveying pipe, and a conveying pipe turning guide structure with a circular box at the bend of the conveying pipe; it also includes a supporting circulating cleaning system, which consists of an inlet pipe, a circulating pump, a cleaning tank, and a return pipe connected in sequence; a chain passes through the conveying pipe, and scraper discs are arranged at intervals on the chain, with a gap between the outer edge of the scraper discs and the inner wall of the conveying pipe; the feeding device includes a feeding hopper connected in series on the conveying pipe and A detachable feeding hopper sealing plate is connected to the feeding hopper opening. The automatic feeding device includes a feeding box connected in series on the conveying pipe, a feeding port provided on the feeding box, and a feeding port sealing plate detachably connected to the feeding port. Several nodes are also provided on the conveying pipe, and node valve assemblies for closing or opening the internal material flow channel of the conveying pipe are connected in series at the node positions. A pair of cleaning ports are provided on both sides of the node valve assembly, and an ultrasonic cleaning device is provided on the node valve assembly. The cleaning system of the tubular chain machine has the following cleaning modes: (1) Large part open static cleaning mode: The large part is defined as the feeding hopper, the unloading box, the tension box, the transmission box and the circular box in the turning guide structure of the conveying pipeline; the tube chain machine is set to stop running state, and the feeding hopper sealing plate on the feeding hopper, the unloading box cover and the unloading port sealing plate on the unloading box, the tension box cover on the tension box, the transmission box cover on the transmission box and the circular box of the half-assembled structure are disassembled to manually clean and wash the inside of the large part; (2) Large part open dynamic cleaning mode: The large part is defined as the feeding hopper, the unloading box, the tension box, the transmission box and the circular box in the turning guide structure of the conveying pipeline; the tube chain machine is set to the stopped running state, and the feeding hopper sealing plate on the feeding hopper, the unloading box cover and the unloading port sealing plate on the unloading box, the tension box cover on the tension box, the transmission box cover on the transmission box and the circular box of the half-assembled structure are disassembled respectively. The node valve assembly is set to the open state, and the tube chain machine is started to run empty, so that the chain with scraper disc moves in a cycle. The high pressure cleaning gun is used to manually clean and wash the inside of the large part and the chain with scraper disc that is moving in a cycle inside the large part. (3) Closed-loop dynamic ultrasonic circulation cleaning mode of the whole machine: The feeding hopper is closed with the feeding hopper sealing plate and the feeding port of the feeding box is closed with the feeding port sealing plate; the liquid inlet pipe of the circulation cleaning system is connected to the cleaning interface on the tension box, and the liquid return pipe of the circulation cleaning system is connected to the cleaning interface on the transmission box, so that a pair of conveying pipes located between the tension box and the transmission box are connected in parallel and then connected in series in the circulation cleaning loop of the circulation cleaning system. The node valve assembly is set to the open state, and the tube chain machine is started to run empty, so that the chain with scraper plate moves in circulation in the conveying pipe. At the same time, the circulation pump is turned on so that the cleaning liquid inside the tube chain machine flows from the tension box through a pair of parallel conveying pipes to the transmission box side, thereby forming a circulation cleaning of the cleaning liquid between the tube chain machine and the circulation pump. During the circulation cleaning, the ultrasonic cleaning device on the node valve assembly is also turned on to stimulate the ultrasonic vibration of the cleaning liquid in the conveying pipe, thereby realizing the closed-loop dynamic ultrasonic circulation cleaning of the entire tube chain machine. (4) Closed-loop static ultrasonic circulation cleaning mode: The tubular chain machine is set to the stopped running state, one of the node valve components on the conveying pipeline is set to the closed state, and the other node valve components are set to the open state; the inlet and return pipes of the circulation cleaning system are respectively connected to a pair of cleaning interfaces on both sides of the node valve component in the closed state, so that the conveying pipeline of the tubular chain machine is connected to the circulation cleaning loop of the circulation cleaning system. The circulation pump of the circulation cleaning system is turned on, so that the cleaning liquid is forced to pass through the gap between the scraper and the conveying pipeline, thereby forming a circulation cleaning of the cleaning liquid between the conveying pipeline and the circulation pump of the tubular chain machine. During the circulation cleaning, the ultrasonic cleaning device on each node valve component is also turned on to drive the chain in the conveying pipeline to vibrate ultrasonically and stimulate the cleaning liquid in the conveying pipeline to vibrate ultrasonically, thereby realizing the static ultrasonic circulation cleaning of the pipeline inside the conveying pipeline. (5) Static ultrasonic circulation cleaning mode of pipeline: The pipe chain machine is set to the stopped running state, the node valve assembly on the two adjacent nodes of the conveying pipeline is set to the closed state, the inlet and return pipes of the circulation cleaning system are connected to the cleaning interface on the transition connection pipe of the node valve assembly on the two adjacent nodes respectively, the circulation pump of the circulation cleaning system is turned on, so that the cleaning liquid is forced through the gap between the scraper and the conveying pipeline, thereby forming a circulation flow cleaning of the cleaning liquid between the conveying pipeline and the circulation pump located between the two adjacent nodes. During the circulation flow cleaning, the ultrasonic cleaning device on the node valve assembly is also turned on to drive the chain in the conveying pipeline to vibrate ultrasonically, thereby realizing the static ultrasonic circulation cleaning of the pipeline inside the conveying pipeline. (6) Static ultrasonic self-circulation cleaning mode for large parts: Define the large parts as circular boxes in the feeding hopper, unloading box, tensioning box, transmission box and the turning guide structure of the conveying pipeline; set the node valve assembly on the conveying pipeline adjacent to the large parts to the closed state, set the pipe chain machine to the stopped running state, connect the liquid inlet pipe and return pipe of the circulation cleaning system to a pair of cleaning interfaces on the large parts respectively, turn on the circulation pump of the circulation cleaning system, so that the cleaning liquid is circulated between the large parts and the circulation pump. When the circulation is circulated, the ultrasonic cleaning device on the node valve assembly adjacent to the large parts is also turned on to drive the chain in the large parts to vibrate ultrasonically, thereby forming a static ultrasonic self-circulation cleaning of the large parts.

[0007] Preferably, the pair of cleaning ports on the large component can be arranged on both sides of the large component to achieve convection cleaning of the cleaning fluid along both sides of the large component.

[0008] In this invention, the cleaning system of the tubular chain machine can adopt the following cleaning method: First, the large component open static cleaning mode, the large component open dynamic cleaning mode, the whole machine closed dynamic ultrasonic circulation cleaning mode, the whole machine closed static ultrasonic circulation cleaning mode, the pipeline static ultrasonic circulation cleaning mode, and the large component static ultrasonic self-circulation cleaning mode are used in sequence to complete the first stage cleaning of the tubular chain machine; then, the pipeline static ultrasonic circulation cleaning mode and the large component static ultrasonic self-circulation cleaning mode are used alternately to complete several alternating cleaning cycles of the tubular chain machine to achieve the second stage cleaning of the tubular chain machine; then, the whole machine closed dynamic ultrasonic circulation cleaning mode and the whole machine closed static ultrasonic circulation cleaning mode are used in sequence to perform the third stage cleaning of the tubular chain machine.

[0009] In this invention, the node valve assembly includes a valve body, transition connecting pipes respectively disposed on both sides of the valve body for series connection with a conveying pipeline, a through hole transversely disposed on the valve body relative to the axis of the transition connecting pipe and communicating with the transition connecting pipe, a pair of valve covers respectively detachably installed at both ends of the through hole, a pair of valve blocks respectively disposed on one side of the pair of valve covers and sealingly fitted with the inner wall of the through hole, and a mating block disposed at the front end of the valve block. The mating blocks at the front end of the pair of valve blocks abut against each other along the axial direction of the through hole, and semi-circular holes for sealing the internal chain of the conveying pipeline are respectively provided on the mating surfaces of the mating blocks at the front end of the pair of valve blocks. After the mating blocks at the front end of the pair of valve blocks are mated, the material flow channel between the transition connecting pipes on both sides of the valve body is separated at the valve block, forming a closed state of the node valve assembly.

[0010] In this invention, a pair of flow channel adapter blocks are provided on the other side of the pair of valve covers. An inner arc surface is provided on the side of the flow channel adapter block away from the valve cover. When the valve cover is rotated 180 degrees and installed in the through hole, the pair of flow channel adapter blocks are aligned with each other and the inner arc surface on the pair of flow channel adapter blocks forms a flow channel with the same diameter as the inner diameter of the transition connecting pipe at the point where the pair of flow channel adapter blocks are aligned, thereby forming the open state of the node valve assembly.

[0011] In this invention, the transition connecting pipe is connected in series to the conveying pipeline via a valve body mounting flange; a cleaning interface for connecting to a circulating cleaning system is respectively provided on the transition connecting pipe on both sides of the valve body, and a removable plug is provided on the cleaning interface.

[0012] As a further improvement of the present invention, the valve cover is also provided with an ultrasonic cleaning device. The ultrasonic cleaning device includes an elastic buffer block, a vibrator mounting plate and an ultrasonic vibrator connected in sequence between the valve cover and the flow channel adapter block. The cable of the ultrasonic vibrator is led out from the valve cover and connected to an ultrasonic generator.

[0013] Note that after the ultrasonic cleaning device is installed between the valve cover and the flow channel adapter block, the valve cover and the flow channel adapter block are actually completely separated by the elastic buffer block and the transducer mounting plate. Therefore, when the ultrasonic transducer vibrates, its vibration energy is mainly concentrated on the flow channel adapter block.

[0014] Preferably, the flow channel adapter block is provided with a seat hole, the ultrasonic transducer is built into the seat hole of the flow channel adapter block, and is encapsulated inside the seat hole by the transducer mounting plate.

[0015] Preferably, the elastic buffer block is a rubber elastic buffer block.

[0016] Preferably, only one of the pair of flow channel adapters is equipped with an ultrasonic cleaning device. The flow channel adapter with the ultrasonic cleaning device is fitted with a clearance fit to the through hole on the valve body, ensuring that it does not contact the through hole. This maximizes the effect of ultrasonic energy on the cleaning fluid within the conveying pipe.

[0017] Preferably, the ultrasonic cleaning device can also be disposed between the mating block at the front end of the valve block and the valve block, and includes an elastic buffer block, a vibrator mounting plate and an ultrasonic vibrator connected in sequence between the valve block and the mating block, wherein the cable of the ultrasonic vibrator is led out from the valve cover and connected to an external ultrasonic generator.

[0018] Note that after the ultrasonic cleaning device is installed on the valve block, the valve block and the mating block are actually completely separated by the elastic buffer block and the transducer mounting plate. Therefore, when the ultrasonic transducer vibrates, its vibration energy is mainly concentrated on the mating block.

[0019] Preferably, the mating block is provided with a seat hole, the ultrasonic transducer is built into the seat hole of the mating block, and is encapsulated inside the seat hole of the mating block by the transducer mounting plate.

[0020] Preferably, only one of the pair of valve blocks needs to be equipped with an ultrasonic cleaning device.

[0021] Preferably, the circulating cleaning system includes a cleaning tank, a circulating pump connected to the cleaning tank, an inlet pipe disposed at the outlet of the circulating pump, and a return pipe disposed on the cleaning tank.

[0022] One of the cleaning ports on the valve body is connected to the circulating pump via the inlet pipe, and the other cleaning port on the valve body is connected to the cleaning tank via the return pipe.

[0023] In this invention, a filter screen is installed in the cleaning tank, which divides the cleaning tank into a dirt-blocking chamber and a liquid supply chamber. The circulating pump is connected to the liquid supply chamber of the cleaning tank, and the return pipeline is connected to the dirt-blocking chamber of the cleaning tank.

[0024] In this invention, the circulating pump is a high-pressure circulating pump.

[0025] Preferably, a sealing ring is provided between the valve block and the through hole.

[0026] Preferably, the pair of valve blocks are fitted with sealing strips along the semicircular hole and their mating surfaces.

[0027] In this invention, scraper discs are arranged at intervals on the chain inside the conveying pipe of the tubular chain machine, and a gap is provided between the outer edge of the scraper disc and the inner wall of the conveying pipe.

[0028] Preferably, the through hole on the valve body is a rectangular cross-section through hole, which is formed by wire cutting.

[0029] The present invention provides a node valve assembly for cleaning control of conveying pipeline of a tubular chain machine. It can be installed on the conveying pipeline in one or more ways, and can achieve cleaning in the case of closing or opening the node valve assembly according to different cleaning requirements, which is highly flexible.

[0030] In this invention, the two installation methods of the valve body, one forward and one reverse, determine two different cleaning operation methods.

[0031] The cleaning operation method using a single node valve assembly in the case of closure in this invention is as follows: The feed hopper and discharge port of the tubular chain conveyor are pre-sealed with sealing plates to form an annular sealed channel structure inside the conveyor. The circulating cleaning system is connected to a pair of cleaning ports on the node valve assembly. The circulating pump is turned on to allow the cleaning fluid to circulate between the tubular chain conveyor and the circulating pump (the cleaning fluid circulates through the gap between the scraper and the inner wall of the conveying pipe). The ultrasonic cleaning device on the valve block is turned on. The ultrasonic transducer drives the chain inside the conveying pipe to vibrate together, so that the ultrasonic vibration energy is transmitted through the chain to all parts of the conveying pipe, which excites the cavitation of the cleaning fluid and realizes ultrasonic circulating cleaning inside the conveying pipe.

[0032] The cleaning operation method of the node valve assembly in the open state in this invention is as follows: The feed hopper and discharge port of the tubular chain conveyor are pre-sealed with sealing plates to form an annular sealed channel structure inside the conveyor. The node valve assembly is set to a closed state, thus separating the annular sealed channel at the node valve assembly. The inlet and return pipes of the circulating cleaning system are connected to the tension box and transmission box of the tubular chain conveyor, respectively, thereby forming a cleaning circulation loop between the pair of conveying pipes between the tension box and the transmission box and the circulating pump (at this time, the pair of conveying pipes are set in parallel in the cleaning circulation loop, and the cleaning fluid inside them moves in the same direction). The tubular chain conveyor is turned on, causing the chain of the conveyor to circulate in the conveying pipe. The ultrasonic cleaning device on the flow channel adapter block is turned on, and the ultrasonic vibration energy of the ultrasonic transducer is directly transmitted to the cleaning fluid circulating inside the conveying pipe, realizing ultrasonic circulation cleaning inside the conveying pipe.

[0033] Note that in order to achieve a thorough cleaning effect, the large components of the tubular chain machine (tension box, transmission box, feeding box and feeding hopper, etc.) need to be disassembled and pre-cleaned manually. After pre-cleaning, the node valve assembly and the circulating cleaning system are used to perform the above two circulating cleaning operations.

[0034] When multiple node valve assemblies are installed on the conveying pipeline, the inlet and return pipelines of the circulating cleaning system can be connected to the cleaning interfaces of two adjacent node valve assemblies. The two adjacent node valve assemblies are set to the closed state, and the circulating pump and the ultrasonic cleaning device on the valve block are turned on to realize ultrasonic forced circulation cleaning inside the conveying pipeline between the two adjacent node valve assemblies.

[0035] The beneficial effects of this invention are: First, the cleaning system for a tubular chain conveyor of the present invention allows for cleaning of the entire conveying pipeline system without major disassembly, except for the internal parts of large shell-like components such as the feeding hopper, feeding box, tensioning box, transmission box, and circular boxes in the turning guide structure of the conveying pipeline, which require manual cleaning by removing the covers. By using the node valve assembly installed on the conveying pipeline, overall ultrasonic circulation cleaning and local ultrasonic circulation cleaning of the entire conveying pipeline system of the tubular chain conveyor can be achieved. This facilitates the cleaning and maintenance of the conveying pipeline of the tubular chain conveyor, shortens the cleaning and maintenance time cycle, and improves the cleaning effect.

[0036] Secondly, the cleaning system of the tubular chain machine of the present invention is equipped with cleaning modes, which can realize the combination and alternating cleaning of multiple cleaning modes, thereby greatly improving the cleaning quality.

[0037] Third, in the cleaning system of the tubular chain machine of the present invention, during dynamic ultrasonic circulation cleaning, the ultrasonic cleaning device can transmit the energy of ultrasonic vibration to the cleaning fluid flowing in the conveying pipe, thereby achieving comprehensive ultrasonic cleaning in the conveying pipe; during dynamic ultrasonic circulation cleaning, the chain drive system of the tubular chain machine, when activated, can realize that the chain with scraper disc moves and is ultrasonically cleaned in the conveying pipe, which is beneficial to thoroughly remove the adhering material on the chain and scraper disc, thereby improving the cleaning quality of the entire chain and scraper disc.

[0038] Fourth, in the cleaning system of the tubular chain machine of the present invention, during static ultrasonic circulation cleaning, a pair of blocks on the ultrasonic cleaning device can not only seal and press the chain, but also drive the chain to vibrate ultrasonically, thereby improving the overall ultrasonic cleaning capability in the conveying pipeline, and thus further improving the thoroughness of ultrasonic circulation cleaning inside the pipeline.

It also includes a circulating cleaning system 84, which consists of an inlet pipe 92, a circulating pump 91, a cleaning tank 90, and a return pipe 93 connected in sequence. A chain 05 passes through the conveying pipe 29, and scraper discs 30 are spaced apart on the chain 05. A gap is provided between the outer edge of the scraper discs 30 and the inner wall of the conveying pipe 29. The feeding device 97 includes components connected in series with the conveying pipe 29. The pipeline 29 includes a feeding hopper 98 and a feeding hopper sealing plate 99 detachably connected to the opening of the feeding hopper 98. The automatic feeding device 32 includes a feeding box 33 connected in series on the conveying pipeline 29, a feeding port 34 provided on the feeding box 33, and a feeding port sealing plate 100 detachably connected to the feeding port 34. Several nodes X are also provided on the conveying pipeline 29, and node valve assemblies for closing or opening the internal logistics channel of the conveying pipeline 29 are connected in series at the node X positions. A pair of cleaning interfaces 85 are provided on both sides of the node valve assembly, and an ultrasonic cleaning device 86 is provided on the node valve assembly. The cleaning system of the tubular chain machine has the following cleaning modes: (1) Large part open static cleaning mode: The large part is defined as the feeding hopper 98, the unloading box 33, the tension box 01, the transmission box 102 and the circular box 53 in the conveying pipe turning guide structure 51; the tube chain machine is set to stop running state, and the feeding hopper sealing plate 99 on the feeding hopper 98, the unloading box cover 44 and the unloading port sealing plate 100 on the unloading box 33, the tension box cover 31 on the tension box 01, the transmission box cover 101 on the transmission box 102 and the circular box 53 of the half-assembled structure are disassembled to manually clean and wash the inside of the large part; (2) Large part open dynamic cleaning mode: The large part is defined as the feeding hopper 98, the unloading box 33, the tension box 01, the transmission box 102 and the circular box 53 in the conveying pipeline turning guide structure 51; the tube chain machine is set to the stopped running state, and the feeding hopper sealing plate 99 on the feeding hopper 98, the unloading box cover 44 and the unloading port sealing plate 100 on the unloading box 33, the tension box cover 31 on the tension box 01, the transmission box cover 101 on the transmission box 102 and the circular box 53 of the half-assembled structure are disassembled respectively. The node valve assembly is set to the open state, and the tube chain machine is started to run in the dry run, so that the chain 05 with scraper 30 moves in a cycle. The high pressure cleaning gun is used to manually clean and wash the inside of the large part and the chain 05 with scraper 30 that is moving in a cycle inside the large part.

When the machine is set to the open state, the tubular chain machine is started for no-load operation, so that the chain 05 with scraper 30 moves in circulation within the conveying pipe 29. At the same time, the circulation pump 91 is started, so that the cleaning fluid inside the tubular chain machine flows from the tension box 01 through a pair of parallel conveying pipes 29 toward the transmission box 102. This forms a circulating flow of cleaning fluid between the tubular chain machine and the circulation pump 91. During the circulating flow cleaning, the ultrasonic cleaning device 86 on the node valve assembly is also turned on to stimulate ultrasonic vibration of the cleaning fluid in the conveying pipe 29, thereby realizing closed-loop dynamic ultrasonic circulating cleaning of the entire tubular chain machine.

[0055] Note that after the ultrasonic cleaning device 86 is installed on the valve block 75, the valve block 79 and the mating block 79-1 are actually completely separated by the elastic buffer block 87 and the vibrator mounting plate 88. Therefore, when the ultrasonic vibrator 89 vibrates, its vibration energy is mainly concentrated on the mating block 79-1.

[0056] Preferably, the mating block 79-1 is provided with a seat hole, the ultrasonic transducer 89 is built into the seat hole of the mating block 79-1, and is encapsulated inside the seat hole of the mating block 79-1 by the transducer mounting plate 88.

[0060] In this embodiment, a filter screen 94 is provided in the cleaning tank 90, which divides the cleaning tank 90 into a dirt-blocking chamber 95 and a liquid supply chamber 96. The circulating pump 91 is connected to the liquid supply chamber 96 of the cleaning tank 90, and the return pipeline 93 is connected to the dirt-blocking chamber 95 of the cleaning tank 90.

[0061] In this embodiment, the circulation pump 91 is a high-pressure circulation pump.

[0062] Preferably, a sealing ring is provided between the valve block 79 and the through hole 77.

[0063] Preferably, the pair of valve blocks 79 are fitted with sealing strips along the semicircular hole 80 and their mating surfaces.

[0064] In this embodiment, scraper discs 30 are arranged at intervals on the chain 05 inside the conveying pipe 29 of the tubular chain machine, and a gap is provided between the outer edge of the scraper disc 30 and the inner wall of the conveying pipe 29.

[0065] Preferably, the through hole 77 on the valve body 75 is a rectangular cross-section through hole 77, which is formed by wire cutting.

[0066] This embodiment provides a node valve assembly for cleaning control of the conveying pipeline of a tubular chain machine. One or more node valve assemblies can be installed on the conveying pipeline 29, and cleaning can be performed in the closed or open state of the node valve assembly according to different cleaning requirements, which provides good flexibility.

[0067] In this embodiment, the two installation methods of the valve body 75, one forward and one reverse, determine two different cleaning operation methods.

[0068] The cleaning operation method using a single node valve assembly in this embodiment is as follows: The feed hopper and discharge port of the tubular chain conveyor are pre-sealed with sealing plates to form an annular sealed channel structure inside the conveyor. The node valve assembly is set to a closed state so that the annular sealed channel is separated at the node valve assembly. The circulating cleaning system 84 is connected to a pair of cleaning ports 85 on the node valve assembly. The circulating pump 91 is turned on so that the cleaning fluid circulates between the tubular chain conveyor and the circulating pump 91 (the cleaning fluid circulates through the gap between the scraper disc 30 and the inner wall of the conveying pipe 29). The ultrasonic cleaning device 86 on the valve block 79 is turned on. The ultrasonic transducer 89 drives the chain 05 inside the conveying pipe 29 to vibrate together, so that the ultrasonic vibration energy is transmitted to all parts inside the conveying pipe 29 through the chain 05, which excites the cavitation of the cleaning fluid and realizes ultrasonic circulating cleaning inside the conveying pipe 29.

[0069] The cleaning operation method with the node valve assembly in the open state in this embodiment is as follows: The feed hopper and discharge port of the tubular chain machine are pre-sealed with sealing plates to form an annular sealed channel structure inside the tubular chain machine; the node valve assembly is set to a closed state so that the annular sealed channel is separated at the node valve assembly; the inlet pipe 92 and return pipe 93 of the circulating cleaning system 84 are connected to the tension box 01 and transmission box 102 of the tubular chain machine respectively, so that a cleaning circulation loop is formed between a pair of conveying pipes 29 between the tension box 01 and the transmission box 102 and the circulating pump 91 (at this time, a pair of conveying pipes 29 are set in parallel in the cleaning circulation loop, and the cleaning liquid inside them moves in the same direction); the tubular chain machine is turned on so that the chain 05 of the tubular chain machine circulates in the conveying pipe 29, and the ultrasonic cleaning device 86 on the flow channel adapter block 81 is turned on. The ultrasonic vibration energy of the ultrasonic transducer 89 is directly transmitted to the cleaning liquid circulating inside the conveying pipe 29 to realize ultrasonic circulation cleaning inside the conveying pipe.

[0070] Note that in order to achieve a thorough cleaning effect, the large components of the tubular chain machine (tension box 01, transmission box 102, feeding box 33 and feeding hopper 98, etc.) need to be disassembled and pre-cleaned manually. After pre-cleaning, the node valve assembly and the circulating cleaning system 84 are used to perform the above two circulating cleaning methods.

[0071] When multiple node valve assemblies are installed on the conveying pipeline 29, the inlet pipe 92 and return pipe 93 of the circulating cleaning system 84 can be connected to the cleaning interface 85 of two adjacent node valve assemblies, the two adjacent node valve assemblies are set to the closed state, and the circulating pump 91 and the ultrasonic cleaning device 86 on the valve block 79 are turned on to realize ultrasonic forced circulation cleaning inside the conveying pipeline 29 between the two adjacent node valve assemblies.

[0072] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
