Description

Technical Field

[0001] This application belongs to the field of hydrocarbon generation simulation technology, and specifically relates to a cleaning device for the internal components of a hydrocarbon generation simulation instrument. Background Technology

[0002] The reactor of a hydrocarbon generation simulator contains circular components such as a sample chamber, sealing ring, and base. After prolonged operation and contact with various experimental samples, these components, including the central hole, accumulate contaminants such as oil and sample residue, affecting the accuracy and stability of the instrument. Therefore, regular cleaning of the components inside the reactor is crucial.

[0003] Currently, cleaning the central holes of the aforementioned circular components inside the reactor of a hydrocarbon generation simulator mainly relies on manual operation. Operators must use cleaning tools, such as brushes and cloths, to wipe and scrub the central holes of each component individually. Manual cleaning is not only time-consuming and labor-intensive, but it is also difficult to ensure consistency in the force, angle, and cleaning time for each operation. Furthermore, different operators have different techniques; some may apply too little force, leaving dirt residue, while others may apply too much force, damaging the inner surface of the components, especially the dirt deep within the central holes. Manual cleaning makes it difficult to ensure complete coverage and thorough removal of dirt, resulting in inconsistent quality of the cleaned components and consequently affecting the reliability of subsequent experimental data from the instrument. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a cleaning device for the internal components of a hydrocarbon generation simulator, in order to solve the technical problem that manual cleaning of the components to be cleaned inside the reactor in the prior art is not only time-consuming and labor-intensive, but also difficult to guarantee the cleaning effect.

[0005] The objective of this invention is achieved as follows: A cleaning device for the internal components of a hydrocarbon generation simulation instrument's reactor, comprising: A brushing pipe fitting is formed by continuously passing through the center holes of multiple components to be cleaned and connecting the multiple components to be cleaned in series. The two ends of the brushing pipe fitting are fixed, and the outer wall of the brushing pipe fitting has bristles. First linear drive mechanism; Two second linear drive mechanisms are connected to the first linear drive mechanism; The head-end clamping mechanism and the tail-end clamping mechanism are respectively connected to two second linear drive mechanisms. The first linear drive mechanism is used to drive the head-end clamping mechanism and the tail-end clamping mechanism to move to the corresponding position of any component to be cleaned. The second linear drive mechanism is used to drive the head-end clamping mechanism and the tail-end clamping mechanism to move at both ends of the component to be cleaned. The head-end clamping mechanism and the tail-end clamping mechanism are used to clamp the brushing pipe fitting. The lifting platform is slidably connected to the lifting slide rail, which is arranged parallel to the brushing pipe fitting. A rolling mechanism is provided on the lifting platform. The part to be cleaned is placed on the rolling mechanism and is configured to contact the side wall of the part to be cleaned under the drive of the lifting platform and drive the part to be cleaned to roll. Before the head clamping mechanism and the tail clamping mechanism clamp the brushing pipe fitting, the lifting platform moves upward, causing the component to be cleaned to move upward. The inner wall below the center hole of the component to be cleaned can be in close contact with the brushing pipe fitting, and then rises with the component to be cleaned. When the position detection sensor detects that the brushing pipe fitting has reached a fixed position, the lifting stops.

[0006] Furthermore, the brushing fitting has multiple liquid outlet holes evenly distributed on it. The starting end of the brushing fitting is fixed on a fixed base, and the tail end of the brushing fitting is connected to a water pump. The water pump can supply cleaning solvent and water to the brushing fitting.

[0007] Furthermore, it also includes two auxiliary holding mechanisms, respectively disposed on the head end clamping mechanism and the tail end clamping mechanism, for abutting against the side wall of the brushing pipe fitting when the brushing pipe fitting brushes the inner wall of the center hole, so as to hold the brushing pipe fitting against the inner wall of the center hole, and simultaneously hold the part to be cleaned together with the rolling mechanism. The auxiliary holding mechanisms are also configured to reciprocate along the axis of the center hole.

[0008] Furthermore, the auxiliary abutment mechanism includes an auxiliary rotating shaft, a rotating bracket, a telescopic cylinder, an abutment member, and an auxiliary rotating motor. The auxiliary rotating motor is driven and connected to the auxiliary rotating shaft, the rotating bracket is connected to the auxiliary rotating shaft, the telescopic cylinder is connected to the rotating bracket, and the abutment member is connected to the telescopic end of the telescopic cylinder. The telescopic cylinder can drive the abutment member to extend into the central hole. The abutment member accurately abuts against the brushing pipe through the rotation of the auxiliary rotating motor and the telescopic movement of the telescopic cylinder, and can move along the axis of the central hole.

[0009] Furthermore, the first linear drive mechanism includes a lead screw device, and a first track is connected to the slider of the lead screw device. The second linear drive mechanism includes a drive housing and a second linear motor. The second linear motor is connected to the drive housing, and the drive housing is slidably connected to the first track. The second linear motor meshes with teeth opened at the bottom of the first track through a gear set.

[0010] Furthermore, the head-end clamping mechanism includes an arc-shaped seat, an arc-shaped locking rod, and a clamping motor. The arc-shaped locking rod is connected to the arc-shaped seat via a sliding sleeve. The inner wall of the arc-shaped seat has a connecting opening. The inner ring of the arc-shaped locking rod has teeth. The clamping motor is connected to the arc-shaped seat and meshes with the arc-shaped locking rod through the connecting opening via a gear set. The arc-shaped locking rod can slide out from one end of the arc-shaped seat and abut against the other end of the arc-shaped seat.

[0011] Furthermore, the outer wall of the brushing pipe fitting is provided with multiple fixing members, each including multiple spaced fixing rings. The multiple fixing members are positioned according to the length of the component to be cleaned, so that each component to be cleaned has a fixing member at both ends.

[0012] Furthermore, the arc-shaped seat and the arc-shaped locking rod of the head clamping mechanism are provided with corresponding teeth on their abutting end faces. The teeth of both can engage in the interval of the fixing ring to lock the brushing fitting. The brushing fitting is a flexible hose. When cleaning the part to be cleaned, the cleaning process starts from the starting end of the brushing fitting.

[0013] Furthermore, the rolling mechanism includes a rolling seat, a rolling motor, and a rolling wheel. The rolling seat is connected to the lifting platform, the rolling motor is disposed inside the rolling seat, and the rolling wheel is rotatably connected to the rolling seat. The rolling motor is drivenly connected to the rolling wheel.

[0014] Furthermore, the rolling wheels include multiple ones, which are disposed on both sides of the rolling seat. The rolling wheels are distributed on opposite sides of the side wall of the part to be cleaned, and the rolling mechanism and the lifting platform include multiple sets.

[0015] Furthermore, the auxiliary abutment mechanism on the head end clamping mechanism enters through the first end opening of the central hole, and the cleaning length of the central hole is c; the auxiliary abutment mechanism on the tail end clamping mechanism enters through the second end opening of the central hole, and the cleaning length of the central hole is e; the length of the central hole is d, 1 / 2d < c < 3 / 5d, c + e = d.

[0016] Compared with the prior art, the cleaning equipment for the internal components of the reactor of the hydrocarbon generation simulation instrument provided by the present invention can achieve at least one of the following beneficial effects: 1. Automated, batch cleaning of reactor internals is achieved, resulting in high cleaning efficiency and excellent cleaning effect. By continuously inserting brushing pipes through the central holes of multiple components to be cleaned in series, and coordinating with head-end clamping mechanisms, tail-end clamping mechanisms, and a lifting platform, the system ensures consistent contact between the brushing pipes and the inner wall of the central hole of each component during each cleaning cycle, thus guaranteeing the same cleaning effect for all components. Furthermore, during the cleaning process, each mechanism operates according to a predetermined procedure, ensuring that each component experiences the same brushing tension (clamping and lifting parameters can be pre-tested and determined based on component characteristics). This avoids the problem of residual dirt caused by inconsistent force, angle, and time during manual cleaning, ensuring the stability and consistency of component quality after cleaning and improving the reliability of subsequent experimental data.

[0017] 2. By combining the first linear drive mechanism, the second linear drive mechanism, the head clamping mechanism, and the tail clamping mechanism, the device can be precisely driven to the corresponding position of any part to be cleaned and accurately positioned at both ends of the part. This achieves automated positioning and clamping of the cleaning pipes. The entire cleaning process does not require manual hand-held tools to wipe and brush each part. After the experiment is completed, the cleaning equipment can be started after the parts are removed and placed. The equipment can then complete a series of cleaning actions in an orderly manner, from part positioning and pipe clamping to rolling brushing, until all connected parts are cleaned. This improves cleaning efficiency and reduces labor costs and labor intensity.

[0018] 3. With the help of the rolling mechanism operating on the lifting platform, the rolling wheels, driven by the rolling motor, contact the side wall of the part to be cleaned and cause the part to roll. Combined with the bristles on the outer wall of the brush, as the part rolls, the bristles generate continuous friction contact with the inner wall of the central hole, which can achieve all-round cleaning of the inner wall of the central hole without dead angles. This solves the problem that manual cleaning is difficult to penetrate deep into the central hole and difficult to fully cover and remove dirt, ensuring that the central hole is thoroughly cleaned.

Example

[0025] A specific embodiment of the present invention discloses a cleaning device for the internal components of a hydrocarbon generation simulation instrument, hereinafter referred to as "cleaning device", which is used to clean the components inside the reaction vessel. The components inside the reaction vessel include components such as sample chambers, sealing rings, and seats. These components, which are generally in the form of rings or hollow cylinders, are the components to be cleaned 11. Each of these components to be cleaned has a central hole 12, and the diameter and length of the central hole 12 of each component to be cleaned are different.

[0026] like Figures 1 to 3As shown, the cleaning equipment for the internal components of the reactor of the hydrocarbon generation simulation instrument includes a brushing pipe 10, a first linear drive mechanism 20, two second linear drive mechanisms 30, a head clamping mechanism 40, a tail clamping mechanism 50, a rolling mechanism 60, and a lifting platform 70. The brushing pipe 10 continuously passes through the central holes 12 of multiple components 11 to be cleaned, connecting the multiple components 11 in series. Both ends of the brushing pipe 10 are fixed, and the outer wall of the brushing pipe 10 has bristles. The two second linear drive mechanisms 30 are connected to the first linear drive mechanism 20. The head clamping mechanism 40 and the tail clamping mechanism 50 are respectively connected to the two second linear drive mechanisms 30. The first linear drive mechanism 20 drives the head clamping mechanism 40 and the tail clamping mechanism 50 to move to the corresponding position of any component 11 to be cleaned. The second linear drive mechanisms 30 drive the head clamping mechanism 40 and the tail clamping mechanism 50 to the corresponding position of any component 11 to be cleaned. The end clamping mechanism 50 moves at both ends of the component 11 to be cleaned. The head end clamping mechanism 40 and the tail end clamping mechanism 50 are used to clamp the brushing pipe fitting 10. The lifting platform 70 is slidably connected to the lifting slide rail 71, which is parallel to the brushing pipe fitting 10. The rolling mechanism 60 is set on the lifting platform 70. The component 11 to be cleaned is placed on the rolling mechanism 60 and can contact the side wall of the component 11 to be cleaned under the drive of the lifting platform 70 and drive the component 11 to be cleaned to roll. Before the head end clamping mechanism 40 and the tail end clamping mechanism 50 clamp the brushing pipe fitting 10, the lifting platform 70 moves upward to drive the component 11 to be cleaned to move upward. The inner wall below the center hole 12 of the component 11 to be cleaned can be in close contact with the brushing pipe fitting 10. Then it rises with the component 11 to be cleaned. When the position detection sensor detects that the brushing pipe fitting 10 has reached the fixed position, the lifting stops.

[0027] By utilizing the coordinated operation of the first linear drive mechanism 20, the second linear drive mechanism 30, the head clamping mechanism 40, and the tail clamping mechanism 50, each component 11 to be cleaned can be accurately positioned, and the relative position of the brushing pipe 10 and the center hole 12 of the component 11 to be cleaned can be ensured to be accurate and consistent in each operation. This avoids the problem of inconsistent cleaning results caused by differences in operators during manual cleaning, and ensures the stability of cleaning quality.

[0028] During the cleaning process, the lifting platform 70 lifts the component 11 to be cleaned, so that the brushing pipe 10 is in close contact with the inner wall of the central hole 12. The rolling mechanism 60 drives the component to roll, and the brush bristles on the outer wall of the brushing pipe 10 are in frictional contact with the inner wall of the central hole 12 to achieve all-round cleaning of the inner wall of the central hole 12, solving the problem that it is difficult to thoroughly clean the dirt deep in the central hole 12 manually.

[0029] The lifting platform 70 moves upward, causing the component 11 to be cleaned to move upward as well. The inner wall below the central hole 12 of the component 11 can then be tightly pressed against the scrubbing pipe 10. The component 11 continues to rise until the scrubbing pipe 10 is raised to a fixed position detectable by the position detection sensor, at which point the lifting stops. This configuration ensures pressure between the scrubbing pipe 10 and the inner wall of the central hole 12, facilitating cleaning of the central hole 12. It also ensures precise positioning of each component, providing a reference position. For shorter components or components with inconsistent central hole 12 sizes, the clamping position of the scrubbing pipe 10 can be adjusted to ensure uniform force on the inner wall of the central hole 12. It is important to note that the fixed position remains constant in the vertical direction, but can be changed in the horizontal direction.

[0030] The brushing fitting 10 has multiple liquid outlet holes evenly distributed on it. The starting end of the brushing fitting 10 is fixed on the fixed base, and the tail end of the brushing fitting 10 is connected to the water pump 13. The water pump 13 can supply cleaning solvent and water to the brushing fitting 10. During the brushing process, the cleaning solvent or water can be evenly sprayed onto the inner wall of the central hole 12 through the liquid outlet holes, which helps to dissolve and rinse the dirt and further improve the thoroughness of the cleaning.

[0031] According to the cleaning requirements, the supply of cleaning solvent and water, as well as the supply time, can be controlled by the water pump 13 to achieve flexible adjustment of the cleaning fluid supply during the cleaning process, adapting to the cleaning of parts with different levels of contamination.

[0032] When the cleaning equipment is started to perform the cleaning operation, the water pump 13 delivers the cleaning solvent or water into the brushing pipe 10 according to the set program or manual control. The cleaning liquid is evenly sprayed onto the inner wall of the central hole 12 of the part to be cleaned 11 through the liquid outlet on the brushing pipe 10, and the bristles of the brushing pipe 10 are used to flush and dissolve the dirt.

[0033] In some embodiments, an auxiliary holding mechanism 80 is further provided on the head end clamping mechanism 40 and the tail end clamping mechanism 50, respectively, for holding against the side wall of the brushing pipe 10 when the brushing pipe 10 brushes the inner wall of the center hole 12, so as to hold the brushing pipe 10 against the inner wall of the center hole 12, and simultaneously hold the part to be cleaned 11 against the rolling mechanism 60 together. The auxiliary holding mechanism 80 is also configured to reciprocate along the axis of the center hole 12.

[0034] The auxiliary holding mechanism 80 is respectively installed on the head end clamping mechanism 40 and the tail end clamping mechanism 50. When the brushing pipe 10 brushes the inner wall of the center hole 12, it can hold the brushing pipe 10 against the side wall of the brushing pipe 10 and hold the brushing pipe 10 against the inner wall of the center hole 12. This ensures that the brushing pipe 10 is in close contact with the inner wall of the center hole 12, so that the bristles can better play the cleaning role. This avoids the technical problem that the holding force is evenly distributed in the length direction of the center hole 12 due to the parallel arrangement of the brushing pipe 10 and the center hole 12, resulting in insufficient brushing pressure.

[0035] At the same time, the part to be cleaned 11 is held together with the rolling mechanism 60 to prevent the part from shifting or shaking during the rolling cleaning process, ensuring the stability of the cleaning process and further guaranteeing the cleaning quality.

[0036] The auxiliary holding mechanism 80 can reciprocate along the axis of the central hole 12, enabling the brushing fitting 10 to effectively brush the inner wall of the central hole 12 at different positions, achieving all-round and thorough cleaning of the inner wall of the central hole 12.

[0037] During the cleaning operation, after the head clamping mechanism 40 and the tail clamping mechanism 50 clamp the brushing fitting 10, the auxiliary holding mechanism 80 begins to function, extending into the central hole 12 to hold the brushing fitting 10 against the inner wall of the central hole 12, and to stabilize the component to be cleaned 11 against the rolling mechanism 60. During the cleaning process, the auxiliary holding mechanism 80 can reciprocate along the axis of the central hole 12 according to a set program or control signal, driving the brushing fitting 10 to be brushed at different positions within the central hole 12. At the same time, the rolling mechanism 60 drives the component to roll, working together to complete the comprehensive cleaning of the inner wall of the central hole 12.

[0038] In some embodiments, the auxiliary supporting mechanism 80 includes an auxiliary rotating shaft 801, a rotating bracket, a telescopic cylinder 802, a supporting member 803, and an auxiliary rotating motor 804. The auxiliary rotating motor 804 is drivenly connected to the auxiliary rotating shaft 801, the rotating bracket is connected to the auxiliary rotating shaft 801, the telescopic cylinder 802 is connected to the rotating bracket, and the supporting member 803 is connected to the telescopic end of the telescopic cylinder 802. The telescopic cylinder 802 can drive the supporting member 803 to extend into the central hole 12; wherein, a brushing pipe is provided. The component 10 is set along the x-direction, and the a-direction is the extension direction of the telescopic cylinder 802. The auxiliary rotary motor 804 rotates in the plane formed by xa, with the rotation points on the head clamping mechanism 40 and the tail clamping mechanism 50, respectively. This allows the abutting component 803 to accurately abut against the brushing pipe component 10 through the rotation of the auxiliary rotary motor 804 and the extension and retraction of the telescopic cylinder 802, and to move along the axis of the central hole 12. During the movement, the abutting component 803 always abuts against the brushing pipe component 10.

[0039] Through the coordinated operation of the auxiliary rotary motor 804, auxiliary rotary shaft 801, rotary bracket, telescopic cylinder 802, and holding member 803, the holding member 803 can be accurately held against the brushing tube 10 and can move along the axis of the central hole 12, ensuring that the brushing tube 10 remains in contact with the inner wall of the central hole 12 throughout the cleaning process. This arrangement allows the holding member 803 to transmit pressure to one position of the brushing tube 10, improving the cleaning effect.

[0040] Since the auxiliary rotary motor 804 can rotate within the plane formed by x and xa, it drives the supporting member 803 to rotate towards the brushing pipe 10. Furthermore, the extension and retraction direction of the telescopic cylinder 802 coordinates with the rotational action, allowing the auxiliary supporting mechanism 80 to flexibly adapt to the center hole 12 of the component 11 to be cleaned, which varies in size and shape. This ensures effective support and precise movement of the brushing pipe 10 under various conditions, expanding the applicability of the cleaning equipment. In this embodiment, the x-direction is arbitrary; for example, in this embodiment, the x-direction can be set to the direction indicated by any straight line in the horizontal plane.

[0041] In this embodiment, the auxiliary rotary motor 804 rotates in the plane composed of xa with a point as the center, and this point is called the rotation point.

[0042] In this embodiment, the end of the abutment member 803 is provided with an abutment groove, and a portion of the sidewall of the brushing tube 10 can engage with the abutment groove, with a gap between the abutment groove and the brushing tube 10. This ensures that the brushing tube 10 remains stable when it comes into contact with the rotating part to be cleaned 11.

[0043] Assume the brushing fitting 10 is positioned along the x-direction, and the a-direction is the extension direction of the telescopic cylinder 802. During the cleaning operation, the auxiliary rotary motor 804 rotates in the plane formed by xa according to the control signal, with the rotation points located at the head clamping mechanism 40 and the tail clamping mechanism 50, respectively. Simultaneously, the telescopic cylinder 802 drives the abutment 803 to extend into the central hole 12. Through the rotation of the auxiliary rotary motor 804 and the extension and retraction of the telescopic cylinder 802, the abutment 803 is accurately held against the brushing fitting 10. During the cleaning process, as the cleaning action progresses, the abutment 803 can move along the axis of the central hole 12 under the drive of the telescopic cylinder 802, and always maintains abutment against the brushing fitting 10. Specifically, the auxiliary rotary motor 804 controls the angle between the telescopic cylinder 802, the supporting member 803, and the brushing tube 10. The telescopic cylinder 802 controls the distance the supporting member 803 extends into the central hole 12. With the two moving in coordination, the depth of the supporting member 803 in the central hole 12 changes, while the angle with the brushing component also changes. For example, when the supporting member 803 enters from the central hole 12, the driving end of the telescopic cylinder 802 extends, and the angle between the driving end, the supporting member 803, and the brushing tube 10 changes from large to small.

[0044] In some embodiments, the first linear drive mechanism 20 includes a lead screw device 201, and a first track 202 is connected to the slider of the lead screw device 201. The second linear drive mechanism 30 includes a drive housing 301 and a second linear motor 302. The second linear motor 302 is connected to the drive housing 301, and the drive housing 301 is slidably connected to the first track 202. The second linear motor 302 meshes with the teeth opened at the bottom of the first track 202 through a gear set.

[0045] The first linear drive mechanism 20 employs a lead screw device 201, with a first track 202 connected to its slider. The second linear drive mechanism 30, through a drive housing 301, a second linear motor 302, and a meshing structure with the first track 202, drives and positions the head-end clamping mechanism 40 and the tail-end clamping mechanism 50. It can accurately move the head-end clamping mechanism 40 and the tail-end clamping mechanism 50 to the corresponding position of any part 11 to be cleaned, and perform precise movement and positioning at both ends of the part.

[0046] When the cleaning equipment starts the cleaning process, the lead screw device 201 of the first linear drive mechanism 20 drives the first track 202 to move via a slider, which in turn drives the drive housing 301 of the second linear drive mechanism 30, which is slidably connected to the first track 202. The second linear motor 302 meshes with the teeth at the bottom of the first track 202 via a gear set, thereby achieving precise movement of the head clamping mechanism 40 and the tail clamping mechanism 50 connected to the second linear drive mechanism 30. First, the head clamping mechanism 40 and the tail clamping mechanism 50 are moved to the corresponding position of any part 11 to be cleaned, and then they are driven to move and position precisely at both ends of the part, completing the positioning and clamping operation before cleaning according to a predetermined program.

[0047] The head-end clamping mechanism 40 includes an arc-shaped seat 401, an arc-shaped locking rod 402, and a clamping motor 403. The arc-shaped locking rod 402 is slidably connected to the arc-shaped seat 401. The inner wall of the arc-shaped seat 401 is provided with a connection opening. The inner ring of the arc-shaped locking rod 402 is provided with teeth. The clamping motor 403 is connected to the arc-shaped seat 401 and meshes with the arc-shaped locking rod 402 through the connection opening via a gear set. The arc-shaped locking rod 402 can slide out from one end of the arc-shaped seat 401 and abut against the other end of the arc-shaped seat 401.

[0048] The head-end clamping mechanism 40, through the cooperation of components such as the arc-shaped seat 401, the arc-shaped locking rod 402, and the clamping motor 403, can achieve a stable clamping of the brushing pipe fitting 10. The sliding connection between the arc-shaped locking rod 402 and the arc-shaped seat 401, and the meshing control of the gear set, allow the arc-shaped locking rod 402 to slide out from one end of the arc-shaped seat 401 and abut against the other end, effectively preventing the brushing pipe fitting 10 from loosening or falling off during the cleaning process, ensuring the smooth progress of the cleaning work.

[0049] The clamping motor 403 makes it easier to control the arc-shaped locking rod 402. The opening and closing action of the arc-shaped locking rod 402 can be controlled according to the needs of the cleaning process, so as to realize the quick clamping and release of the brushing pipe fitting 10 and improve the operation convenience of the cleaning equipment.

[0050] Before the cleaning operation, when it is necessary to clamp the brushing fitting 10, the clamping motor 403 starts. The gear set passes through the connecting opening in the inner wall of the arc-shaped seat 401 and engages with the teeth of the inner ring of the arc-shaped locking rod 402. This drives the arc-shaped locking rod 402 to slide out from one end of the arc-shaped seat 401 and abut against the other end, thus clamping the brushing fitting 10 between the arc-shaped seat 401 and the arc-shaped locking rod 402. After cleaning, the clamping motor 403 rotates in the opposite direction, causing the arc-shaped locking rod 402 to return to its initial position, releasing the brushing fitting 10, and completing one cleaning cycle of clamping operation.

[0051] The head clamping mechanism 40 and the tail clamping mechanism 50 have the same structure and the same working method.

[0052] In some embodiments, the outer wall of the brushing pipe fitting 10 is provided with a plurality of fixing members 101. The fixing members 101 include a plurality of fixing rings 102, and the plurality of fixing rings 102 are spaced apart. The plurality of fixing members 101 are positioned according to the length of the component 11 to be cleaned, so that each component 11 to be cleaned has a fixing member 101 at both ends.

[0053] Multiple fasteners 101 are provided on the outer wall of the cleaning pipe fitting 10, and their corresponding positions are set according to the length of the component 11 to be cleaned, so that there is a fastener 101 at both ends of each component 11 to be cleaned. In this way, the relative position of the cleaning pipe fitting 10 and the component 11 to be cleaned can be more accurately positioned during the cleaning process, while keeping the clamped part of the cleaning pipe fitting 10 unobstructed.

[0054] By setting different positions of the fixing parts 101 according to the different lengths of the parts 11 to be cleaned, the cleaning equipment can better adapt to parts 11 of various lengths to be cleaned, thereby improving the versatility and applicability of the cleaning equipment.

[0055] The retaining ring 102 is made of metal, which has good strength and hardness and is easy to clamp.

[0056] The arc-shaped seat 401 and the arc-shaped locking rod 402 of the head clamping mechanism 40 are provided with corresponding teeth 103. The teeth 103 of the two can be engaged in the gap of the fixing ring 102 to lock the brushing pipe 10. The brushing pipe 10 is a flexible hose. When cleaning the part 11 to be cleaned, it starts from the starting end of the brushing pipe 10.

[0057] The arc-shaped seat 401 and arc-shaped locking rod 402 of the head clamping mechanism 40 are provided with corresponding teeth 103 on their abutting end faces, which can engage intermittently with the fixing ring 102 on the outer wall of the brushing fitting 10, reliably locking the brushing fitting 10. On the one hand, this clamps the brushing fitting 10, and on the other hand, it prevents the solution of the brushing fitting 10 from continuing to deliver liquid to the starting end of the refreshing fitting through this position, avoiding repeated rinsing of previously cleaned parts. The tail clamping mechanism 50 is clamped on the fixing member 101.

[0058] Since the cleaning pipe fitting 10 is a flexible hose, and the cleaning of the component 11 to be cleaned is specified to start from the beginning of the cleaning pipe fitting 10, the components can be cleaned in a predetermined order, avoiding chaos during the cleaning process and improving the orderliness and efficiency of the cleaning.

[0059] Before the cleaning operation, when the head clamping mechanism 40 and the tail clamping mechanism 50 clamp the brushing pipe fitting 10, the teeth 103 of the abutting end face of the arc-shaped seat 401 and the arc-shaped locking rod 402 engage with the fixing ring 102 on the outer wall of the brushing pipe fitting 10 at intervals, so as to firmly lock the brushing pipe fitting 10 in the corresponding position.

[0060] In some embodiments, the rolling mechanism 60 includes a rolling seat 602, a rolling motor, and rolling wheels 601. The rolling seat 602 is connected to the lifting platform 70. The rolling motor is disposed inside the rolling seat 602. The rolling wheels 601 are rotatably connected to the rolling seat 602. The rolling motor and the rolling wheels 601 are drivenly connected. Multiple rolling wheels 601 are disposed on both sides of the rolling seat 602. The rolling wheels 601 are distributed on opposite sides of the sidewall of the component 11 to be cleaned. The rolling mechanism 60 and the lifting platform 70 include multiple sets.

[0061] The rolling mechanism 60 includes multiple rolling wheels 601 arranged on both sides of the rolling seat 602, distributed on opposite sides of the side wall of the part 11 to be cleaned, and the rolling motor drives the rolling wheels 601 to rotate. This allows driving force to be applied simultaneously from both sides of the part, enabling the part 11 to be cleaned to roll more comprehensively and evenly under the drive of the lifting platform 70. This ensures that all parts of the part can fully contact the bristles of the cleaning pipe 10 during the cleaning process, improving the comprehensiveness and effectiveness of the cleaning. By setting multiple sets of rolling mechanisms 60 and lifting platforms 70, it is possible to adapt to parts 11 of different sizes and shapes to be cleaned. The appropriate combination of rolling mechanisms 60 and lifting platforms 70 can be selected according to the specific situation of the part for cleaning, expanding the applicability of the cleaning equipment.

[0062] During the cleaning process, when the lifting platform 70 rises to the predetermined position, the head clamping mechanism 40 and the tail clamping mechanism 50 clamp the brushing pipe 10, and the rolling motor of the rolling mechanism 60 starts, driving the rolling wheel 601 to rotate. The rolling wheel 601 contacts the side wall of the part 11 to be cleaned and applies driving force, causing the part to roll on the lifting platform 70. Since the rolling wheels 601 are distributed on opposite sides of the side wall of the part, the part can be driven to roll from both sides simultaneously. During the rolling process, the bristles of the brushing pipe 10 rub against the inner wall of the central hole 12 of the part, achieving a thorough cleaning of the inner wall of the central hole 12. At the same time, multiple sets of rolling mechanisms 60 and lifting platforms 70 can be flexibly configured and used according to the different parts.

[0063] Since the rollers 601 are distributed on opposite sides of the side wall of the component, and the abutment 803 is distributed on one side of the inner wall of the central hole 12, the two form a triangular fixing function to stably fix the component 11 to be cleaned.

[0064] In one optional embodiment, the auxiliary abutment mechanism 80 on the head-end clamping mechanism 40 enters through the first end opening of the central hole 12, and the cleaning length of the central hole 12 is c; the auxiliary abutment mechanism 80 on the tail-end clamping mechanism 50 enters through the second end opening of the central hole 12, and the cleaning length of the central hole 12 is e; the length of the central hole 12 is d, 1 / 2d < c < 3 / 5d, c + e = d. That is, the length of the cleaning movement trajectory of one of the two auxiliary abutment mechanisms 80 on the head-end clamping mechanism 40 and the tail-end clamping mechanism 50 within the central hole 12 is c; wherein the cleaning movement trajectory starts from the first end opening of the central hole 12 and ends at a predetermined position in the middle part of the central hole 12, 1 / 2d < c < 3 / 5d, and the length of the cleaning movement trajectory of the other auxiliary abutment mechanism 80 is e, c + e = d; In one cleaning cycle, the auxiliary abutment mechanism 80 on the tail clamping mechanism 50 moves by a length c, and the auxiliary abutment mechanism 80 on the head clamping mechanism 40 moves by a length e. In the next cleaning cycle, the cleaning distances are swapped so that the auxiliary abutment mechanism 80 on the head clamping mechanism 40 moves by a length c, and the auxiliary abutment mechanism 80 on the tail clamping mechanism 50 moves by a length e, and the movement time of the two auxiliary abutment mechanisms 80 in one cycle is the same.

[0065] During the cleaning process, in one cleaning cycle, the auxiliary holding mechanism 80 on the tail-end clamping mechanism 50 moves within the central hole 12 by a predetermined length c, while the auxiliary holding mechanism 80 on the head-end clamping mechanism 40 moves within the central hole 12 by a length e, and their movement durations are the same. During this process, the brushing fitting 10 moves within the central hole 12 along with the auxiliary holding mechanism 80, brushing the inner wall of the central hole 12. In the next cleaning cycle, the movement lengths of the two auxiliary holding mechanisms 80 are reversed: the auxiliary holding mechanism 80 on the head-end clamping mechanism 40 moves by length c, and the auxiliary holding mechanism 80 on the tail-end clamping mechanism 50 moves by length e, again with the same movement duration. Through this alternating movement, the brushing fitting 10 can repeatedly move within a certain range in the middle of the central hole 12, achieving comprehensive cleaning of the inner wall of the central hole 12 and avoiding brushing the four corners.

[0066] The lengths of the central holes 12 of the various components to be cleaned are different. For example, if the length of the central hole 12 of one component to be cleaned is 10cm, the auxiliary holding mechanism 80 on the tail-end clamping mechanism 50 moves within the central hole 12 at a predetermined distance of 5.5cm, while the auxiliary holding mechanism 80 on the head-end clamping mechanism 40 moves within the central hole 12 at a distance of 4.5cm. Their movement times are the same. It should be noted that in actual operation, both should be reduced by a predetermined value at this length to maintain a gap when the two holding members 803 are close together, avoiding interference. During this process, the brushing tube 10 moves within the central hole 12 along with the movement of the auxiliary holding mechanism 80, brushing the inner wall of the central hole 12. In the next cleaning cycle, the moving distances of the two auxiliary holding mechanisms 80 are swapped. That is, the auxiliary holding mechanism 80 on the head clamping mechanism 40 moves a distance of 5.5cm, and the auxiliary holding mechanism 80 on the tail clamping mechanism 50 moves a distance of 4.5cm. In this way, the central hole 12 can be fully cleaned within the overlapping area of ​​the two.

[0067] After the hydrocarbon generation simulation experiment, the sample chamber, sealing ring, and seat body of the component to be cleaned 11 are removed from the reactor. The component to be cleaned 11 is placed on the rolling mechanism 60. The brushing pipe 10 is continuously passed through the central holes 12 of multiple components to be cleaned 11 and connected in series. The rolling mechanism 60 is set on the lifting platform 70, which slides along the lifting rail 71 parallel to the brushing pipe 10 to move the component to be cleaned 11 to their respective appropriate positions. After the cleaning equipment is started, the lifting platform 70 moves upward, driving the component to be cleaned 11 upward until the inner wall below the central hole 12 of the component to be cleaned 11 is tightly attached to the brushing pipe 10, and continues to rise until the brushing pipe 10 reaches the fixed position that can be detected by the position detection sensor. At this time, the lifting stops, and the initial positioning preparation of the component to be cleaned 11 is completed.

[0068] The first linear drive mechanism 20 operates, driving the two second linear drive mechanisms 30 connected thereto to move, thereby causing the head clamping mechanism 40 and the tail clamping mechanism 50 to reach the corresponding position of any component 11 to be cleaned; subsequently, the second linear drive mechanism 30 drives the head clamping mechanism 40 and the tail clamping mechanism 50 to move and position precisely at both ends of the component 11 to be cleaned. During the movement, they must also reach the fixed position determined by the position sensor to prepare for clamping the brushing pipe 10, ensuring that the starting position of the subsequent cleaning action is accurate.

[0069] The head clamping mechanism 40 and the tail clamping mechanism 50 firmly clamp the brushing pipe 10. Then, the lifting platform 70 rises a predetermined distance, so that the brushing pipe 10 and the inner wall of the center hole 12 generate a predetermined tension force. The tension pressure of each cleaning component is the same. This tension force can be tested in advance to determine the clamping position of the brushing pipe 10 and the rising distance of the lifting platform 70, so as to ensure that the clamping force is consistent.

[0070] The rolling mechanism 60 is started on the lifting platform 70. The rolling wheel 601 rotates under the drive of the rolling motor, contacts the side wall of the part to be cleaned 11 and drives the part to be cleaned 11 to roll. As the part rolls, the inner wall of the center hole 12 of the part to be cleaned is thoroughly brushed and cleaned by the friction contact between the brushing pipe 10 and the inner wall of the center hole 12 of the part to be cleaned 11.

[0071] Once a component is cleaned, the first linear drive mechanism 20 drives the relevant mechanism to move again, repeating the above positioning, clamping, and cleaning actions for the next component 11 to be cleaned, until all components 11 connected in series on the brushing pipe 10 have completed the cleaning work, realizing an automated, batch, and efficient cleaning process for the central hole of the circular component of the hydrocarbon generation simulator.

[0072] Compared with the prior art, the cleaning equipment for the internal components of the reactor of the hydrocarbon generation simulation instrument provided in this embodiment can achieve at least one of the following beneficial effects: By continuously threading the brushing fitting 10 through the central holes 12 of multiple components 11 to be cleaned in series, and cooperating with the head clamping mechanism 40, tail clamping mechanism 50, and lifting platform 70, the contact state between the brushing fitting 10 and the inner wall of the central hole 12 of the component 11 to be cleaned is ensured to be consistent during each cleaning process. In the initial positioning stage, the lifting platform 70 lifts the component 11 to be cleaned until the inner wall below the central hole 12 is in close contact with the brushing fitting 10, and then raises it to a fixed position for inspection, establishing the basis for subsequent cleaning. During the cleaning process, each mechanism operates according to a predetermined procedure, ensuring that each component experiences the same brushing tension (the clamping and lifting parameters can be pre-tested based on the component characteristics), avoiding the problem of dirt residue caused by inconsistent force, angle, and time during manual cleaning. This ensures the stability and consistency of the component quality after cleaning and improves the reliability of subsequent experimental data.

[0073] By utilizing the combination of the first linear drive mechanism 20, the second linear drive mechanism 30, the head clamping mechanism 40, and the tail clamping mechanism 50, the device can be precisely driven to the corresponding position of any component 11 to be cleaned and accurately positioned at both ends of the component, achieving automated positioning and clamping of the brushing operation of the pipe fitting 10. The entire cleaning process does not require manual hand-held tools to wipe and brush each component individually. After the experiment is completed, the components are unloaded and placed, and the cleaning equipment is started. It can then complete a series of cleaning actions in an orderly manner, from component positioning and pipe clamping to rolling brushing, until all connected components are cleaned, thereby improving cleaning efficiency and reducing labor costs and labor intensity.

[0074] 3. With the help of the rolling mechanism 60 operating on the lifting platform 70, the rolling wheel 601, driven by the rolling motor, contacts the side wall of the part to be cleaned 11 and drives the part to be cleaned 11 to roll. Combined with the bristles on the outer wall of the brushing pipe fitting 10, as the part rolls, the bristles generate continuous friction contact with the inner wall of the central hole 12, which can achieve all-round cleaning of the inner wall of the central hole 12 without dead angles. This solves the problem that manual cleaning is difficult to penetrate deep into the central hole 12 and difficult to fully cover and remove dirt, ensuring that the central hole 12 is thoroughly cleaned.

[0075] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this application. It should be understood that the above are only specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
