Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, and particularly relates to a high-efficiency cleaning device for a material cylinder. BACKGROUND

[0002] In modern industrial production, various material cylinders are widely used in the material storage, conveying and processing processes in the chemical industry, pharmaceutical industry, food processing industry and plastic processing industry. After long-term use, the inner wall of the material cylinder will be attached with various residues, scale and pollutants, which seriously affects the product quality and production efficiency, and therefore, the material cylinder needs to be cleaned regularly.

[0003] At present, the following methods are mainly used for cleaning the material cylinder: 1. manual disassembly and cleaning, which needs to completely disassemble the material cylinder for cleaning, and is large in workload, low in efficiency and easy to damage the equipment; 2. using a high-pressure water gun or steam cleaning, which is strong in cleaning force but difficult to clean the complex structure inside the material cylinder, and is not thorough in cleaning; 3. using chemical cleaning agent for soaking, which can effectively dissolve the pollutants but is large in cleaning agent consumption, difficult to recover and causes resource waste and environmental pollution; and 4. using a simple brushing tool, which is limited in cleaning effect and large in labor intensity.

[0004] The prior art uses a single cleaning method or a simple mechanical device to clean the material cylinder, but still has certain limitations, such as: low cleaning efficiency, which needs to be repeatedly operated for multiple times to achieve an ideal effect; low utilization rate of cleaning agent, which is large in waste of cleaning agent, increases the cost and environmental burden; uneven cleaning, which is difficult to ensure the overall cleaning of the inner surface of the material cylinder; complex operation, which needs to be matched with multiple sets of equipment or multiple operation steps; difficult to control the cleaning quality, which is easy to cause cleaning dead angles or over-cleaning; complex structure of the equipment, which is high in maintenance cost and high in failure rate; and inability to simultaneously process chemical cleaning and physical scrubbing, which is limited in processing capacity for composite pollution.

[0005] Therefore, there is an urgent need for a new cleaning device which can efficiently, energy-efficiently and environmentally protectively clean the material cylinder, has accurate distribution and recovery functions of cleaning agent, realizes the organic combination of chemical cleaning and physical scrubbing. SUMMARY

[0006] The present application aims to overcome the deficiencies of the prior art and provide a high-efficiency cleaning device for a material cylinder to solve the above problems.

[0007] The present application aims to overcome the deficiencies of the prior art and provide a high-efficiency cleaning device for a material cylinder to solve the above problems. A cleaning section adapted to extend into the barrel; a piston barrel fixed to the top end of the cleaning section; a piston slidably connected in the piston barrel, the piston dividing the interior of the piston barrel into a cleaning agent filling chamber located below it and a recovery chamber located above it; a push rod, the bottom end of which is connected to the piston, the top end of which passes through the recovery chamber and extends to the outside of the piston barrel; a first handle fixed to the top end of the push rod for driving the piston to move; a cleaning ring sleeved on the outer end of the cleaning section; a cleaning agent dispensing structure for transferring the cleaning agent squeezed by the piston when it moves downward from the cleaning agent filling chamber to the cleaning ring; a cleaning agent recovery structure for recovering excess cleaning agent in the barrel to the recovery chamber, the structure comprising: A reflux inlet is provided at the top and bottom of the cleaning section; at least one reflux pipe is connected to the reflux inlet at one end and to the recovery chamber at the other end; when the piston moves downward under the drive of the first handle, the following functions are simultaneously realized: The cleaning agent in the cleaning agent filling chamber is pressurized so as to be distributed through the cleaning agent distribution structure; a negative pressure is generated in the recovery chamber, thereby sucking the excess cleaning agent into the recovery chamber through the cleaning agent recovery structure; an electromagnetic valve is provided on the piston cylinder and connected to the recovery chamber, and is used to connect the external negative pressure system to provide auxiliary negative pressure to the recovery chamber when the negative pressure generated by the piston itself is insufficient.

[0008] A second handle is also fixedly connected to the outer wall of the piston cylinder, and the second handle is used to operate the entire device to perform axial reciprocating movement in the barrel to achieve physical scrubbing of the inner wall of the barrel.

[0009] The cleaning agent distribution structure includes: a diversion groove opened at the top of the cleaning section and connected with the cleaning agent filling chamber; and a plurality of diversion holes distributed along the axial direction of the cleaning section and connected with the diversion groove.

[0010] The cleaning agent distribution structure also includes a flow balancing ring and a plurality of flow balancing grooves opened at the outer end of the cleaning section, which are used to evenly guide the cleaning agent flowing out of the diversion hole to the cleaning ring.

[0011] The reflux inlet comprises a top cover and a bottom cover, which are respectively fixed to the top and bottom ends of the cleaning section. The connections between the top cover and the bottom cover and the cleaning section respectively form reflux grooves for collecting cleaning agents.

[0012] The cleaning ring is made of porous sponge material and is detachably mounted on the outer end of the cleaning section.

[0013] A sealing ring is provided on the outer periphery of the piston to ensure air-tight and liquid-tight isolation between the cleaning agent filling chamber and the recovery chamber.

[0014] The push rod and the piston are connected by threads.

[0015] The at least one return pipe is distributed in a circumferential array around the axis of the piston cylinder.

[0016] The cleaning agent recovery structure is driven by negative pressure generated by the movement of the piston, or by the negative pressure generated by the piston in cooperation with an external negative pressure system.

[0017] The beneficial effects of the present application are: The simultaneous implementation of cleaning agent pressurization distribution and negative pressure recovery through the single action of the piston fundamentally improves the efficiency of the cleaning operation. In traditional cleaning devices, the delivery and recovery of cleaning agents often require independent systems and multiple operation steps, which not only increases the complexity of the equipment, but also reduces the work efficiency. The present application, through the ingenious structure design, enables the operator to complete the distribution and recovery of cleaning agents by simply pushing and pulling the first handle, greatly simplifying the operation process, reducing the operation time, and improving the overall cleaning efficiency. This integrated design is particularly suitable for industrial environments that require frequent cleaning, and can significantly reduce labor costs and time costs.

[0018] The adopted cleaning agent recovery mechanism is efficient and environmentally friendly, driven by the negative pressure generated by the movement of the piston, which can effectively recover the excess cleaning agent in the barrel to the recovery cavity, avoiding waste of cleaning agent and environmental pollution. The double setting of the backflow inlet at the top and bottom of the cleaning section ensures the comprehensiveness and thoroughness of the recovery, even trace amounts of residual cleaning agent can be effectively recovered. This recovery mechanism not only reduces the consumption cost of cleaning agent, but also meets the requirements of modern industry for environmental protection and sustainable development. For application occasions using expensive or harmful cleaning agents, this recovery function has important economic value and environmental significance.

[0019] The cleaning ring is made of porous sponge material, which has excellent absorbency and permeability. The porous structure allows the cleaning ring to store a large amount of cleaning agent and release it uniformly during the cleaning process, ensuring the continuity and consistency of the cleaning process. Compared with traditional brushes or cloth strips, porous sponge material can better adapt to the shape changes of the inner wall of the barrel, providing more uniform and gentle cleaning contact, avoiding excessive wear or scratching the inner surface of the barrel. In addition, the detachable design of the cleaning ring facilitates replacement and cleaning, prolonging the service life of the device and reducing maintenance costs.

[0020] The organic combination of chemical cleaning and physical scrubbing provides an effective solution for handling complex contamination. Chemical cleaning can dissolve and decompose various chemical contaminants, while physical scrubbing can remove stubborn dirt and scale that is mechanically attached. The synergistic effect of the two cleaning methods enables the present application to handle complex contamination problems that are difficult to solve by traditional single cleaning methods, especially for complex deposits formed after long-term use. This dual cleaning mode shows significant advantages. The axial reciprocating movement function enables physical scrubbing to cover the entire inner surface of the barrel, avoiding the dead angles and blind areas that may be missed by static cleaning.

[0021] The cleaning agent distribution system has been carefully designed to achieve precise control and uniform distribution of the cleaning agent. The multi-stage distribution system composed of diverter troughs, diverter holes, flow-equalizing rings and flow-equalizing troughs ensures that the cleaning agent can be evenly supplied to all areas of the cleaning ring. This refined distribution control avoids local overload or shortage of cleaning agent and ensures consistent cleaning results. At the same time, the multi-stage distribution system can also adjust the flow and distribution of cleaning agent according to different cleaning requirements, providing greater application flexibility.

[0022] The sealing design ensures the reliability and stability of the system. The sealing ring on the outer periphery of the piston ensures effective isolation between the cleaning agent filling chamber and the recovery chamber, preventing cross contamination within the system. This sealing design not only ensures the purity of the cleaning agent, but also ensures the normal operation of the negative pressure recovery system. The sealing ring is made of chemically resistant elastic material and can maintain good sealing performance in various cleaning agent environments, thereby extending the service life of the device.

[0023] The solenoid valve design increases the adaptability and reliability of the system. When the negative pressure generated by the piston itself is not enough to complete effective recovery, the solenoid valve can connect to the external negative pressure system to provide auxiliary negative pressure. This dual-drive mode provides flexible options for different usage conditions. It can rely on mechanical negative pressure to achieve recovery under normal circumstances, and can also use the external negative pressure system to enhance recovery capabilities in high-viscosity cleaning agents or severe contamination. The automatic control function of the solenoid valve can also intelligently adjust the negative pressure intensity according to actual needs to optimize the cleaning effect.

[0024] The design of the first and second handles fully considers the operator's usage habits and comfort, reducing operator fatigue. The dual-handle configuration enables the operator to flexibly control different functions, improving the accuracy and efficiency of operation. The threaded connection between the push rod and the piston not only ensures the effective transmission of force, but also facilitates assembly and maintenance, reducing the difficulty and cost of equipment maintenance.

[0025] The return pipes are distributed in a circular array, ensuring the uniformity and efficiency of the recovery system. This distribution method can evenly collect cleaning agents from different directions, improving the recovery efficiency. At the same time, the circular array distribution also maintains the structural balance of the device, avoiding instability caused by unilateral load, and ensuring the stability and reliability of the device during use.

[0026] It has a wide range of applicability and can meet the cleaning needs of different industries and applications. The basic embodiment is suitable for occasions with general cleaning requirements and has the advantages of simple structure, low cost and easy maintenance. The enhanced embodiment is suitable for occasions with high-standard cleaning requirements and provides more complete cleaning functions and better cleaning effects. This layered technical solution provides suitable choices for different users and expands the market applicability of the product.

[0027] In actual application, it has shown significant economic benefits. The efficient cleaning ability reduces cleaning time and labor costs, the cleaning agent recovery function reduces material consumption costs, and the reliable structural design reduces equipment maintenance costs. For industrial environments that require frequent cleaning, these economic benefits will become more obvious as the use time increases. Especially in fields such as precision industry, food processing, and pharmaceuticals that have extremely high requirements for cleaning quality, the present invention can effectively improve product quality and reduce quality problems and economic losses caused by improper cleaning.

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] It is to be noted that the directions of "left", "right", "up", "down", "front", "back", "inside" and "outside" in the following schemes are all relative directions and are not listed here one by one.

[0032] Example 1: Figures 1 to 12 As shown, this embodiment provides an efficient barrel cleaning device, which adopts a piston-driven cleaning agent distribution and recovery system to achieve efficient cleaning of the inner wall of the barrel.

[0033] The efficient barrel cleaning device includes a cleaning section 1, which is a slender cylindrical structure with an outer diameter suitable for extending into the interior of the barrel 16 to be cleaned, so that the entire device can be flexibly moved and operated in the inner cavity of the barrel 16. The length of the cleaning section 1 is designed to cover the main cleaning area of ​​the barrel 16, and its surface is smooth to reduce friction resistance with the inner wall of the barrel 16.

[0034] The piston cylinder 2 is fixed to the top of the cleaning section 1. The piston cylinder 2 is a hollow cylindrical structure with good strength and sealing performance. The piston cylinder 2 and the cleaning section 1 are firmly fixed by threaded connection or welding to ensure that they will not loosen or separate during use. The inner diameter of the piston cylinder 2 is precisely processed to provide a good fitting clearance for the sliding of the piston 3.

[0035] The piston 3 is slidably connected in the piston cylinder 2. The piston 3 is a disc-shaped structure, and its outer diameter forms a precise match with the inner diameter of the piston cylinder 2. The piston 3 divides the interior of the piston cylinder 2 into a cleaning agent filling chamber located below it and a recovery chamber located above it. The cleaning agent filling chamber is used to store cleaning agent, and its volume is determined according to actual cleaning needs. The recovery chamber is used to collect refluxed cleaning agent to ensure the recycling of the cleaning agent. The piston 3 can slide up and down smoothly in the piston cylinder 2, and the sliding stroke is designed according to the distribution and recovery needs of the cleaning agent.

[0036] The bottom end of the push rod 4 is connected to the piston 3. The push rod 4 is a slender rod-shaped structure with sufficient strength to withstand push and pull forces. The top end of the push rod 4 passes through the recovery chamber and extends to the outside of the piston cylinder 2, so that the operator can apply driving force to the piston 3 from the outside. The push rod 4 and the piston 3 are connected by a threaded connection. The threaded connection not only achieves a firm mechanical connection, but also facilitates assembly and maintenance. The threaded connection is precisely processed to ensure the reliability and durability of the connection.

[0037] The first handle 5 is fixed to the top end of the push rod 4. The first handle 5 provides an operating interface that is easy for the operator to hold. The shape and size of the first handle 5 conform to ergonomic design, which is convenient for the operator to apply push and pull forces. Through the first handle 5, the operator can drive the piston 3 to move in the piston cylinder 2, thereby realizing the distribution and recovery functions of the cleaning agent.

[0038] The cleaning ring 6 is sleeved on the outer end of the cleaning section 1. The cleaning ring 6 is made of a porous sponge material. The porous sponge material has good absorbency and permeability, and can effectively absorb and release the cleaning agent. The porous structure of the cleaning ring 6 enables it to store sufficient cleaning agent and release the cleaning agent evenly to the cleaning surface when it contacts the inner wall of the barrel 16. The cleaning ring 6 is detachably mounted on the outer end of the cleaning section 1, which is convenient for replacement and cleaning, thereby extending the service life of the device.

[0039] The cleaning agent distribution structure is used to transport the cleaning agent squeezed by the piston 3 when it moves downward from the cleaning agent filling chamber to the cleaning ring 6. This distribution structure ensures that the cleaning agent can be supplied to the cleaning ring 6 in a timely and uniform manner to meet the needs of the cleaning operation. The design of the distribution structure takes into account the flow characteristics of the fluid and can generate sufficient pressure under the push of the piston 3 to transport the cleaning agent to the designated location.

[0040] The cleaning agent recovery structure is used to recover excess cleaning agent in the barrel 16 to the recovery chamber. The recovery structure includes a reflux inlet and at least one reflux pipe 14. The reflux inlet is arranged at the top and bottom ends of the cleaning section 1, and can collect the cleaning agent in the barrel 16 from multiple positions. The dual setting of the top and bottom ends ensures the integrity and efficiency of the cleaning agent recovery.

[0041] The specific structure of the reflux inlet includes a top cover 11 and a bottom cover 12. The top cover 11 and the bottom cover 12 are respectively fixed to the top and bottom ends of the cleaning section 1. The connections between the top cover 11 and the bottom cover 12 and the cleaning section 1 respectively form reflux grooves 13 for collecting cleaning agents. The design of the reflux grooves 13 can effectively capture and guide the cleaning agent into the reflux system to prevent leakage and waste of the cleaning agent.

[0042] One end of at least one reflux pipe 14 is connected to the reflux inlet, and the other end is connected to the recovery chamber. The reflux pipe 14 is a thin tubular structure with good fluid transmission performance. At least one reflux pipe 14 is distributed in a circular array around the axis of the piston cylinder 2. This distribution method can evenly collect cleaning agents from different directions and improve recovery efficiency. The circular array distribution can also maintain the structural balance of the device and avoid instability caused by unilateral load.

[0043] When the piston 3 moves downward under the drive of the first handle 5, it realizes two important functions at the same time. First, the cleaning agent in the cleaning agent filling chamber is pressurized so as to be distributed through the cleaning agent distribution structure. The downward movement of the piston 3 reduces the volume of the cleaning agent filling chamber, thereby increasing the pressure inside it, so that the cleaning agent can overcome the pipeline resistance and the resistance of the cleaning ring 6 and be smoothly transported to the cleaning position. Second, a negative pressure is generated in the recovery chamber, so that the excess cleaning agent is sucked into the recovery chamber through the cleaning agent recovery structure. The downward movement of the piston 3 increases the volume of the recovery chamber and generates a negative pressure effect. This negative pressure can suck the excess cleaning agent in the barrel 16 back into the recovery chamber through the reflux pipe 14.

[0044] A sealing ring is provided on the outer periphery of the piston 3 to ensure air-tight and liquid-tight isolation between the cleaning agent filling chamber and the recovery chamber. The sealing ring is made of a chemically corrosion-resistant elastic material and can maintain a good sealing effect during the sliding process of the piston 3. The setting of the sealing ring prevents mutual contamination between the cleaning agent filling chamber and the recovery chamber, ensuring the normal operation of the system.

[0045] The solenoid valve 15 is arranged on the piston cylinder 2 and is connected to the recovery chamber. It is used to connect the external negative pressure system to provide auxiliary negative pressure to the recovery chamber when the negative pressure generated by the piston 3 itself is insufficient. The solenoid valve 15 can automatically or manually control the access of the external negative pressure system according to actual needs to ensure that sufficient negative pressure can be maintained in the recovery chamber for cleaning agent recovery. This design increases the adaptability and reliability of the device.

[0046] The cleaning agent recovery structure is driven by the negative pressure generated by the movement of the piston 3, or by the negative pressure generated by the piston 3 and the external negative pressure system. This dual drive mode provides flexible options for different usage conditions. It can rely on mechanical negative pressure to achieve recovery under normal circumstances, and can also use an external negative pressure system when stronger recovery capabilities are required.

[0047] During the specific working process, first, an appropriate amount of cleaning agent is injected into the cleaning agent filling chamber, and then the device is inserted into the barrel 16 that needs to be cleaned. The operator holds the first handle 5 and pushes the push rod 4 downward, driving the piston 3 to move downward in the piston cylinder 2. The downward movement of the piston 3 applies pressure to the cleaning agent in the cleaning agent filling chamber, causing the cleaning agent to flow into the cleaning ring 6 through the distribution structure. After the porous sponge material in the cleaning ring 6 absorbs the cleaning agent, it contacts the inner wall of the barrel 16, and evenly coats the cleaning agent on the cleaned surface to achieve a chemical cleaning effect.

[0048] At the same time, the downward movement of the piston 3 increases the volume of the recovery chamber, generating negative pressure. This negative pressure acts on the reflux inlet through the reflux pipe 14, sucking the excess cleaning agent in the barrel 16 and the mixture of dirt and cleaning agent generated during the cleaning process into the recovery chamber. The reflux groove 13 effectively collects and guides these reflux materials to ensure the thoroughness of the cleaning process.

[0049] When the negative pressure generated by the piston 3 itself is not enough to complete effective recovery, the solenoid valve 15 can be connected to the external negative pressure system to provide additional negative pressure driving force for the recovery chamber. This coordinated driving method ensures that effective cleaning agent recovery can be achieved under various working conditions.

[0050] During the entire cleaning process, the sealing ring ensures effective isolation between the cleaning agent filling chamber and the recovery chamber, preventing cross-contamination within the system. The threaded connection between the push rod 4 and the piston 3 ensures effective force transmission and structural reliability. The circumferential array distribution of the return pipe 14 ensures the uniformity and efficiency of the recovery system.

[0051] Through the single action of the piston 3, the pressurized distribution and negative pressure recovery of the cleaning agent are simultaneously achieved, which greatly improves the operating efficiency and cleaning effect. Secondly, the cleaning ring 6 adopts a porous sponge material, which can effectively store and release the cleaning agent, ensuring the continuity and uniformity of the cleaning process. Thirdly, the dual setting of the reflux inlet at the top and bottom ends and the circumferential array distribution of the reflux pipe 14 ensure the comprehensiveness and thoroughness of the cleaning agent recovery. In addition, the setting of the solenoid valve 15 provides flexibility for use under different working conditions. It can rely on mechanical negative pressure to work under normal conditions, and can also use an external negative pressure system to enhance the recovery capacity when needed. Finally, the setting of the sealing ring and the use of threaded connection ensure the sealing and structural reliability of the system, and extend the service life of the device.

[0052] The device has a relatively simple structure, low manufacturing cost, easy maintenance, and high reliability. It is particularly suitable for barrel cleaning operations with general cleaning requirements and can effectively improve cleaning quality and work efficiency. Example 2: Figures 1 to 12 As shown, this embodiment provides an enhanced and efficient barrel cleaning device, which, based on the basic technical solution of embodiment one, further adds a physical scrubbing function and an optimized cleaning agent distribution system, which can achieve more thorough and efficient cleaning of the inner wall of the barrel.

[0053] The high-efficiency barrel cleaning device of this embodiment includes all the technical features of the first embodiment, namely, the basic structures such as the cleaning section 1, the piston cylinder 2, the piston 3, the push rod 4, the first handle 5, the cleaning ring 6, the cleaning agent distribution structure, the cleaning agent recovery structure, the reflux inlet, the reflux pipe 14, the sealing ring and the solenoid valve 15. On this basis, this embodiment further adds the following enhanced technical features.

[0054] A second handle 17 is also fixedly connected to the outer wall of the piston cylinder 2. The second handle 17 provides the operator with an additional operation control interface. The design of the second handle 17 fully considers the principles of ergonomics. Its shape, size and surface texture are convenient for the operator to hold firmly. The installation position of the second handle 17 is carefully designed so that the operator can hold the first handle 5 while operating the second handle 17 with the other hand to achieve coordinated operation of both hands. The second handle 17 is firmly connected to the outer wall of the piston cylinder 2 by bolts, welding or integral molding to ensure that it will not loosen or fall off during use.

[0055] The second handle 17 is used to operate the entire device to perform axial reciprocating movement in the barrel 16 to achieve physical scrubbing of the inner wall of the barrel 16. This axial reciprocating movement refers to the device as a whole performing back and forth reciprocating movement along its axial direction in the barrel 16. Through repeated frictional contact between the cleaning ring 6 and the inner wall of the barrel 16, a mechanical scrubbing effect is generated, which can effectively remove stubborn dirt, scaling and sediment attached to the inner wall of the barrel 16. The stroke of the axial reciprocating movement can be adjusted according to the length of the barrel 16 and the degree of contamination to ensure comprehensive and thorough cleaning.

[0056] The cleaning agent distribution structure has been further optimized and refined in this embodiment. The distribution structure includes a diverter groove 7 opened at the top of the cleaning section 1 and connected to the cleaning agent filling chamber. The diverter groove 7 is an annular groove structure and is evenly distributed around the circumference of the cleaning section 1. Its depth and width are precisely designed to accommodate sufficient cleaning agent without affecting the overall strength of the device. The inner surface of the diverter groove 7 is smooth, which reduces the resistance to the flow of the cleaning agent and ensures that the cleaning agent can flow smoothly from the cleaning agent filling chamber into the diverter groove 7.

[0057] The cleaning agent distribution structure also includes a plurality of diverter holes 8 distributed axially along the cleaning section 1 and connected to the diverter groove 7. These diverter holes 8 are evenly distributed on the side wall of the cleaning section 1. The diameter of each diverter hole 8 is precisely calculated to ensure sufficient outflow of the cleaning agent while preventing excessive loss. The axial distribution of the diverter holes 8 ensures that the cleaning agent can be evenly distributed along the entire length of the cleaning section 1, avoiding uneven cleaning caused by the concentration of the cleaning agent in a certain area. The number of diverter holes 8 is determined according to the length of the cleaning section 1 and the cleaning requirements. Usually, a row of diverter holes 8 is set at a certain angle on the circumference of the cleaning section 1 to form a grid-like distribution pattern.

[0058] The cleaning agent distribution structure further includes a flow balancing ring 9 and a plurality of flow balancing grooves 10 opened at the outer end of the cleaning section 1. The flow balancing ring 9 is an annular groove structure, which is arranged on the outer surface of the cleaning section 1, and is used to receive the cleaning agent flowing out of the diversion hole 8 and perform secondary distribution. The design of the flow balancing ring 9 ensures that the cleaning agent flowing out of each diversion hole 8 can be converged into a unified annular channel to achieve pressure balance and flow equalization.

[0059] Multiple flow balancing grooves 10 extend outward from the flow balancing ring 9 and are distributed radially. Each flow balancing groove 10 is a slender groove structure. Its depth and width are optimized to guide the cleaning agent to flow smoothly to the cleaning ring 6. The radial distribution of the flow balancing grooves 10 ensures that the cleaning agent can enter the cleaning ring 6 from multiple directions at the same time, avoiding local overload or uneven distribution that may be caused by single-point entry. The surface of the flow balancing groove 10 is finely processed and has good fluid conduction performance, which can minimize the loss of cleaning agent during the transportation process.

[0060] The synergistic effect of the flow-equalizing ring 9 and the multiple flow-equalizing grooves 10 evenly guides the cleaning agent flowing out of the diversion hole 8 to the cleaning ring 6. This graded distribution system ensures that the cleaning ring 6 can obtain sufficient and uniform supply of cleaning agent, so that the cleaning ring 6 can maintain a good wet state and cleaning ability throughout the cleaning process.

[0061] During the specific working process, the enhanced functions of this embodiment are reflected in the following aspects. First, the operator controls the entire device to perform axial reciprocating movement in the barrel 16 through the second handle 17. This movement is different from the up and down movement of the piston 3. Instead, the entire device as a whole moves back and forth in the axial direction in the barrel 16. During the movement, the cleaning ring 6 maintains close contact with the inner wall of the barrel 16, and removes attached dirt through mechanical friction.

[0062] Secondly, the optimized cleaning agent distribution system ensures the precise supply of cleaning agent. When the piston 3 moves downward under the drive of the first handle 5, the cleaning agent in the cleaning agent filling chamber is squeezed and first flows into the diverter groove 7. Due to the annular design of the diverter groove 7, the cleaning agent can achieve preliminary pressure homogenization therein. Subsequently, the cleaning agent flows out of the diverter groove 7 through multiple diverter holes 8. Due to the axial distribution of the diverter holes 8, the cleaning agent can flow out evenly along the entire length of the cleaning section 1.

[0063] The outflowing cleaning agent is gathered in the flow-equalizing ring 9, and secondary pressure balance is performed in the annular channel of the flow-equalizing ring 9. Then, the cleaning agent is evenly guided to different areas of the cleaning ring 6 through multiple flow-equalizing grooves 10. This multi-stage distribution system ensures that the cleaning ring 6 can obtain sufficient and uniform supply of cleaning agent, so that the cleaning ring 6 can release sufficient cleaning agent for chemical cleaning when it contacts the inner wall of the barrel 16.

[0064] Third, this embodiment realizes the organic combination of chemical cleaning and physical scrubbing. Chemical cleaning dissolves and decomposes dirt through the chemical action of the cleaning agent, while physical scrubbing removes stubborn attachments through mechanical friction. The synergistic effect of the two cleaning methods greatly improves the cleaning effect and can handle various types and degrees of pollution.

[0065] During the axial reciprocating movement, the operator can adjust the speed and amplitude of the movement according to the degree of contamination in different areas of the barrel 16. For areas with less contamination, a faster movement speed can be used for rapid cleaning; for areas with serious contamination, a slower movement speed can be used and the number of reciprocating times can be increased to ensure sufficient cleaning time and friction.

[0066] The cleaning agent recovery function is also enhanced in this embodiment. Due to the existence of axial reciprocating movement, the cleaning agent in the barrel 16 is more evenly distributed, which is beneficial to the operation of the recovery system. The reflux inlet is set at the top and bottom ends of the cleaning section 1, which can effectively collect various cleaning agents and dirt mixtures generated during the reciprocating movement.

[0067] The second handle 17 realizes the coordinated operation of both hands. The operator can use one hand to control the up and down movement of the piston 3 to distribute and recover the cleaning agent, and use the other hand to control the axial reciprocating movement of the entire device for physical scrubbing, which greatly improves the flexibility and efficiency of the operation.

[0068] Secondly, the optimized cleaning agent distribution system achieves precise control and uniform distribution of the cleaning agent through multi-stage distribution of the diverter groove 7, diverter hole 8, flow equalizing ring 9 and flow equalizing groove 10, avoiding waste of cleaning agent and uneven cleaning effect. This refined distribution system is particularly suitable for applications with high requirements for cleaning quality.

[0069] Again, the combination of chemical cleaning and physical scrubbing enables this embodiment to handle more complex and stubborn pollution, and the cleaning effect is qualitatively improved compared to simple chemical cleaning. Physical scrubbing can remove mechanical attachments and scaling that are difficult to handle by chemical cleaning, while chemical cleaning can dissolve chemical pollutants that are difficult to remove by physical scrubbing. The two complement each other.

[0070] In addition, the axial reciprocating movement function enables the device to comprehensively clean the entire inner surface of the barrel 16, avoiding dead corners and blind spots that may be missed by static cleaning. This dynamic cleaning method is particularly suitable for cleaning long barrels or barrels with complex shapes.

[0071] Finally, this embodiment, while maintaining the functionality of the first embodiment, further enhances the functionality and applicability of the device, and can meet higher standards of cleaning requirements. Although the structure is relatively complex, its excellent cleaning effect and wide applicability give it significant technical advantages and economic value in high-end cleaning applications. The device is particularly suitable for fields with extremely high requirements for cleaning quality, such as precision industry, food processing, and pharmaceuticals, and can effectively improve product quality and production efficiency.
