DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] This embodiment provides a cleaning device for a cylindrical device, such as Figure 1 and Figure 2 As shown, it includes a cleaning assembly 1, a guide shaft 2, a first drive assembly 3, an axial drive assembly, a traction assembly 5 and a sewage discharge assembly 6;

[0038] The cleaning component 1 is circumferentially limitedly connected to the guide shaft 2, the guide shaft 2 is rotationally connected to the cylindrical equipment, the first drive component 3 is connected to the guide shaft 2 to drive the guide shaft 2 and then drive the cleaning component 1 to rotate circumferentially to clean the inner wall of the cylindrical equipment; the axial drive component drives the cleaning component 1 axially forward or axially backward relative to the guide shaft 2 through the traction component 5; the sewage discharge component 6 is connected to the cylindrical equipment to discharge the debris generated by cleaning the cylindrical equipment.

[0039] In the specific use process, because the guide shaft 2 is rotatably connected to the cylindrical device, and the cleaning component 1 is circumferentially limitedly connected to the guide shaft 2, the first driving component 3 is started, and the first driving component 3 drives the guide shaft 2 to rotate, and then drives the cleaning component 1 circumferentially limitedly connected to the guide shaft 2 to rotate circumferentially to clean the inner wall of the cylindrical device, so as to achieve repeated cleaning of the inner wall of a certain part of the cylindrical device;

[0040] When the axial drive assembly is started, the axial drive assembly will drive the cleaning assembly 1 to move forward axially relative to the guide rail shaft 2 through the traction assembly 5, so that the cleaning assembly 1 gradually penetrates into the cylindrical device, effectively solving the problem that the current cleaning equipment is difficult to clean or clean the deeper cylindrical device thoroughly; because the axial drive assembly will also drive the cleaning assembly 1 to retreat axially relative to the guide rail shaft 2 through the traction assembly 5, the cleaning assembly 1 that has penetrated into the cylindrical device can be pulled back to the initial position in time;

[0041] In addition, because the cleaning assembly 1 of the cleaning device of this embodiment is located in the cylindrical device, there is no excessive requirement for the volume of the cylindrical device, that is, if the volume of the cylindrical device is large, then the cleaning assembly 1 of this embodiment is relatively large; if the volume of the cylindrical device is small, then the cleaning assembly 1 of this embodiment is relatively small, which effectively solves the problem that the current cleaning equipment is difficult to clean or clean the small cylindrical reaction equipment;

[0042] In addition, because the sewage discharge assembly 6 is connected to the cylindrical device and is used to discharge the debris generated by cleaning the cylindrical device, it is ensured that the debris generated by cleaning the cylindrical device can be quickly discharged from the cylindrical device in a timely manner.

[0043] When using this embodiment, the following method can be used:

[0044] The axial drive assembly is started, and the axial drive assembly drives the cleaning assembly 1 to move axially relative to the guide shaft 2 through the traction assembly 5. When the cleaning assembly 1 moves to the first position (for example Figure 1 and Figure 2 When the axial drive assembly is in position 1), the axial drive assembly is stopped;

[0045] At the same time, the first driving component 3 is started, and the first driving component 3 drives the guide shaft 2 to rotate, and then drives the cleaning component 1 connected to the guide shaft 2 in a circumferential limit direction to rotate. At this time, because the cleaning component 1 is rotating at position 1, it repeatedly cleans the inner wall at position 1 to ensure that it is clean; at the same time, the sewage discharge component 6 starts to work to ensure that the debris generated by cleaning the inner wall is discharged from the cylindrical device in time;

[0046] After the inner wall at position 1 is cleaned, the first drive assembly 3 is stopped and the axial drive assembly is restarted. The axial drive assembly drives the cleaning assembly 1 to move forward axially relative to the guide shaft 2 again through the traction assembly 5. When the cleaning assembly 1 moves to the second position (for example Figure 1 and Figure 2 When the axial drive assembly is in position 2), the axial drive assembly is stopped;

[0047] At the same time, the first driving assembly 3 is started, and the first driving assembly 3 drives the guide shaft 2 to rotate, and then drives the cleaning assembly 1 which is circumferentially limitedly connected to the guide shaft 2 to rotate. At this time, because the cleaning assembly 1 rotates at position 2, it repeatedly cleans the inner wall at position 2 to ensure that it is clean;

[0048] By analogy, the cleaning component 1 gradually penetrates into the cylindrical device under the drive of the axial drive component and the traction component 5, and completes the thorough cleaning of the cylindrical device under the drive of the first drive component 3 to ensure the cleanliness of the cylindrical device;

[0049] When the cleaning component 1 completes cleaning of the cylindrical device, the sewage discharge component 6 stops working, and the axial drive component is started again, driving the cleaning component 1 to retreat axially relative to the guide shaft 2 through the traction component 5 until the cleaning component 1 returns to its initial position.

[0050] In this embodiment, the first driving component 3 may be an electric motor;

[0051] The traction component 5 is fixedly connected to the cleaning component 1. The traction component 5 may be a traction rope. For example, a hook is welded on the cleaning component 1, and the traction component 5 is fixed on the hook.

[0052] In this embodiment, the first driving component 3 can rotate forward or reversely. For example, after the first driving component 3 rotates forward for one circle, it automatically reverses for one circle to reset the cleaning component 1.

[0053] In this embodiment, when cleaning the cylindrical device, the first drive assembly 3 and the axial drive assembly may be started simultaneously, that is, the cleaning assembly 1 is rotated while moving forward to clean the inner wall of the cylindrical device.

[0054] In a specific embodiment, Figure 3-Figure 6 As shown, the cleaning assembly 1 includes a sleeve 11, an air inlet pipe 12, an air outlet pipe 13, an air extraction pipe 14 and a baffle 15;

[0055] The shaft sleeve 11 is circumferentially limited and arranged on the guide shaft 2; the air inlet pipe 12, the air exhaust pipe 14 and the baffle 15 are all fixedly arranged on the shaft sleeve 11; the air inlet pipe 12 is connected with the air outlet pipe 13 for conveying air into the cylindrical device to clean the inner wall of the cylindrical device; the air exhaust pipe 14 is connected with the sewage discharge assembly 6 for extracting the air in the cylindrical device; one end of the baffle 15 away from the shaft sleeve 11 is arranged toward the inner wall of the cylindrical device for preventing the air at one end of the cylindrical device from diffusing to the other end.

[0056] The specific use process is: the air outside the cylindrical device (for example, air at 1.5 atmospheres) is introduced into the cylindrical device through the air inlet pipe 12 and the air outlet pipe 13 in sequence to form an air flow;

[0057] At the same time, the first driving assembly 3 is started, and the first driving assembly 3 drives the guide shaft 2 to rotate, thereby driving the cleaning assembly 1 connected to the guide shaft 2 in a circumferential limit direction to rotate. Because the shaft sleeve 11 is circumferentially limited and arranged on the guide shaft 2, the shaft sleeve 11 rotates with the guide shaft 2.

[0058] Because the air inlet pipe 12, the air exhaust pipe 14 and the baffle 15 are all fixedly arranged on the outer surface of the sleeve 11, and the air inlet pipe 12 is connected with the air outlet pipe 13, the air inlet pipe 12 and the air outlet pipe 13 will rotate with the sleeve 11, thereby forming a rotating airflow, and the circumferentially rotating air will exert a force on the inner wall of the cylindrical device, thereby removing the debris on the inner wall, and the debris is suspended in the cylindrical device driven by the rotating air;

[0059] At this time, in order to timely discharge the above-mentioned debris suspended in the air from the cylindrical device, the sewage discharge component 6 is started. Since the sewage discharge component 6 is connected to the cylindrical device through the exhaust pipe 14, the debris is discharged from the cylindrical device by the sewage discharge component 6 through the exhaust pipe 14;

[0060] After the inner wall is cleaned, the axial drive assembly is started, and the axial drive assembly pulls the cleaning assembly 1 axially forward relative to the guide shaft 2 through the traction assembly 5 until it reaches the next position to be cleaned, and then the axial drive assembly is stopped;

[0061] At the same time, start the first drive component 3 and repeat the above-mentioned cleaning operation; as the cleaning component 1 goes deeper, the inner wall of the cylindrical device is divided into two parts, one part is the inner wall that has been cleaned, and the other part is the inner wall that has not been cleaned. In order to prevent the debris suspended in the air generated by cleaning the inner wall from contaminating the cleaned inner wall, a baffle 15 is fixedly provided on the sleeve 11, and one end of the baffle 15 away from the sleeve 11 is arranged toward the inner wall of the cylindrical device, so that the air with suspended debris can be effectively blocked from diffusing to the cleaned inner wall, thereby causing the cleaned inner wall to be contaminated again.

[0062] In a specific embodiment, as shown in FIG. 7( a ) and FIG. 7( b ), the inner side wall of the sleeve 11 is provided with a slot 111 , and the guide shaft 12 is axially provided with a slot 21 , such as Figure 6 As shown, the inserting tooth 111 is limited in the slot 21 and is slidably connected with the slot 21.

[0063] In this embodiment, the inserting teeth 111 and the slot 21 are clearance-matched, and the inserting teeth 111 are located in the slot 21, so that it is ensured that the sleeve 11 can rotate with the guide shaft 2;

[0064] In addition, because the slot 21 is opened along the axial direction of the guide shaft 2 , when the axial drive assembly is started, the cleaning assembly 1 is driven to move forward axially along the guide shaft 2 through the traction assembly 5 , that is, the inserting teeth 111 slide in the slot 21 .

[0065] Because when the traction assembly 5 pulls the cleaning assembly 1 forward along the guide rail shaft 2, the friction between the cleaning assembly 1 and the guide rail shaft 2 is sliding friction, which not only requires a large traction force, but also causes more serious wear of the cleaning assembly 1 and the guide rail shaft 2;

[0066] So in a specific embodiment, if Figure 3-Figure 6 As shown, and Fig. 9 As shown, the cleaning assembly 1 further includes a bearing 16 , which is located between the shaft sleeve 11 and the guide shaft 2 ; the bearing 16 is fixedly connected to the shaft sleeve 11 , and the bearing 16 and the guide shaft 2 are connected by a ball rolling connection of the bearing 16 .

[0067] When the first driving assembly 3 is started, the shaft head 11 can rotate with the guide shaft 2 because the inserting teeth 111 of the shaft sleeve 11 are inserted into the slot 21 of the guide shaft 2; and because the bearing 16 is fixedly connected to the shaft sleeve 11, the bearing 16 also rotates with the guide shaft 2;

[0068] When the axial drive assembly is started, because the slot 21 is opened along the axial direction of the guide shaft 2, the shaft head 11 will also move forward or backward along the guide shaft 2. However, because the bearing 16 is fixedly connected to the sleeve 11, and is also connected to the guide shaft 2 through the ball rolling connection of the bearing 16, and the spline 111 and the slot 21 have a clearance fit, the bearing 16 will move forward or backward along the guide shaft 2 under the action of the rolling friction between the ball and the guide shaft 2, thereby converting the sliding friction between the sleeve 11 and the guide shaft 2 into the rolling friction between the bearing 16 and the guide shaft 2.

[0069] In a specific embodiment, Fig.10 As shown, the cleaning assembly 1 further includes a bearing gasket 17 , which is connected to the shaft sleeve 11 for limiting the bearing 16 .

[0070] In this embodiment, a flange is further provided on the shaft sleeve 11 , and the flange is hingedly connected to the bearing gasket 17 by bolts to fix the bearing 16 .

[0071] In a specific embodiment, Figure 8 As shown, the air inlet pipe 12 is arranged axially along the guide rail shaft 2, one end of the air outlet pipe 13 is connected to the air inlet pipe 12, and the other end extends toward the inner wall of the cylindrical device;

[0072] In order to ensure a better cleaning effect, in this embodiment, one end of the air outlet pipe 13 is connected to the air inlet pipe 12, and the other end extends toward the inner wall of the cylindrical device.

[0073] In this embodiment, the angle α between the air outlet pipe 13 and the guide rail axis 2 is preferably 45°, so that the force between the air flowing out of the air outlet pipe 13 and the inner wall is relatively large, thereby improving the cleaning efficiency and cleaning effect.

[0074] In a specific embodiment, at least one air outlet 131 is formed on the air outlet pipe 13 . In this embodiment, the air outlets 131 on each air outlet pipe 13 are arranged in a straight line, so that the airflow flowing out of the air outlet 131 becomes a spiral airflow as the air outlet pipe 13 rotates.

[0075] In a specific embodiment, the exhaust pipe 14 is arranged axially along the guide rail axis 2, which is to ensure uniform exhaust and uniform distribution of the center of gravity while taking into account aesthetics.

[0076] In a specific embodiment, the baffle 15 is formed by splicing a plurality of connecting plates to form an umbrella-shaped structure, which has a certain gathering effect on the air in the area to be cleaned and effectively prevents the diffusion of the air.

[0077] In this embodiment, the air outlet pipe 13 is arranged close to the baffle plate 15 and forms an angle α of 45° with the guide rail axis 2 .

[0078] In a specific embodiment, the air inlet pipe 12 and the air exhaust pipe 14 are fixedly arranged on the outer surface of the sleeve 11 at intervals; the air inlet pipe 12 is connected to the air outlet pipe 13. Such an interval arrangement can not only allow clean high-pressure air to diffuse into the space to be cleaned as quickly as possible, but also can extract air with suspended debris as quickly as possible.

[0079] In a specific embodiment, Figure 1 and Figure 2 As shown, the axial drive assembly includes a second drive assembly 4 and a third drive assembly 7; the second drive assembly 4 drives the cleaning assembly 1 axially forward relative to the guide shaft 2 through the traction assembly 5, and the third drive assembly 7 drives the cleaning assembly 1 axially backward relative to the guide shaft 2 through the traction assembly 5.

[0080] For example, when the cleaning component 1 needs to move forward, the second driving component 4 is started; when the cleaning component 1 needs to move backward, the third driving component 7 is started.

[0081] In this embodiment, the second drive assembly 4 and the third drive assembly 7 may be motors; for example, when the second drive assembly 4 is started, the traction assembly 5 (such as a traction rope) will gradually be mixed with the rotating shaft of the second drive assembly 4, thereby driving the cleaning assembly 1 to move axially forward;

[0082] When the cleaning component 1 needs to move backward, the third drive component 7 is started, and the traction component 5 (such as a traction rope) connected to the third drive component 7 is gradually wound around the rotating shaft of the third drive component 7. At the same time, the traction component 5 wound around the rotating shaft of the second drive component 4 is unwound, thereby driving the cleaning component 1 to move backward axially.

[0083] In a specific embodiment, Figure 1As shown, the sewage discharge assembly 6 includes an induced draft fan 61, an induced draft pipe 62 and a filter rod 63; the induced draft fan 61 is arranged on the induced draft pipe 62, the filter rod 63 is located in the induced draft pipe 62, and the induced draft pipe 62 is connected to the cylindrical device;

[0084] Start the induced draft fan 61. Since the induced draft duct 62 is connected to the cylindrical device, the air containing impurities flowing out of the cylindrical device enters the induced draft duct 62 under the action of the induced draft fan 61. Since the filter rod 63 is located in the induced draft duct 62, the air containing impurities is filtered by the filter rod 63. The air passing through the filter rod 63 meets the emission requirements, which effectively avoids the pollution of the atmosphere by impurities such as dust.

[0085] In this embodiment, the air duct 62 can not only be directly connected to the cylindrical device, for example, the air duct 62 is connected to the rear end of the cylindrical device; it can also be connected to the exhaust pipe 14.

[0086] In this way, part of the air containing impurities in the cylindrical device directly enters the induced draft duct 62, and the other part enters the induced draft duct 62 through the exhaust pipe 14. The air entering the induced draft duct 62 finally passes through the filter rod 63, the impurities are blocked by the filter rod 63, and the filtered air is discharged into the atmosphere by the induced draft fan 61.

[0087] In a specific embodiment, the cleaning device further comprises a bin door 8, which is disposed in the cylindrical device;

[0088] In this way, the door 8 divides the tubular device into two parts, one of which is used to park the cleaning assembly 1, and the other is used for reaction. When the inner wall of the tubular device for reaction needs to be cleaned, the door 8 is opened, and the second drive assembly 4 and the first drive assembly 3 are started.

[0089] In a specific embodiment, the cylindrical device can be a rotary kiln, a reactor, a pipeline reactor or a material conveying pipe.

[0090] Take a rotary kiln or reactor as an example, and this rotary kiln or reactor is horizontal, the specific use process is:

[0091] The initial position of the cleaning assembly 1 of this embodiment is located at the leftmost end of the rotary kiln, and the door 8 is closed. When the rotary kiln needs to be cleaned, the door 8 is opened, and the second driving assembly 4 (such as a motor) is started, which will pull the cleaning assembly 1 axially forward along the guide shaft 2 through the traction assembly 5, that is, move to the right. When it moves to the position that needs to be cleaned (such as position 1), the second driving assembly 4 is stopped;

[0092] Clean air (e.g., air at 1.5 atmospheres) is passed into the air inlet pipe 12, and the clean air is ejected from the air outlet 131 of the air outlet pipe 13. At the same time, the first driving assembly 3 (e.g., a motor) is started to drive the guide shaft 2 to rotate. Because the slot 21 is limitedly connected with the inserting teeth 111 of the sleeve 11, and the clearance fit is achieved, and the bearing 16 is also fixedly connected with the sleeve 11, the sleeve 11 and the bearing 16 rotate with the guide shaft 2.

[0093] Since the shaft sleeve 11 is also fixed with the air inlet pipe 12, the air exhaust pipe 14 and the baffle 15, the air inlet pipe 12, the air exhaust pipe 14 and the baffle 15 rotate accordingly, thereby forming a rotating airflow, which fully cleans the inner wall at this position, and the poorly cleaned debris is rolled up by the airflow and suspended in the air;

[0094] At the same time, the induced draft fan 61 is started, and part of the air with suspended impurities enters the induced draft duct 62 through the exhaust pipe 14, and the other part directly enters the induced draft duct 62. The air entering the induced draft duct 62 moves upward under the action of the induced draft fan 61 and is filtered by the filter rod 63. The impurities are blocked by the filter rod 63, and the filtered air is discharged into the atmosphere through the filter rod 63, effectively avoiding air pollution.

[0095] When the cleaning of the inner wall at this location (position 1) is completed, the first driving component 3 is stopped, and the second driving component 4 (e.g., a motor) is started, which will pull the cleaning component 1 along the guide shaft 2 to continue to move to the right through the traction component 5. When it moves to the next location to be cleaned (position 2), the second driving component 4 is stopped;

[0096] At the same time, the first driving component 3 is started to fully clean the inner wall at this position, and so on, until the cleaning component 1 moves to the deepest part of the rotary kiln (that is, moves to the rightmost end of the rotary kiln) and completes the cleaning of the inner wall of the entire rotary kiln;

[0097] At this time, the third driving assembly 7 (such as a motor) is started, and the cleaning assembly 1 is still pulled back through the traction assembly 5, that is, axially retreated, until the cleaning assembly 1 returns to the initial position, and the compartment door 8 is closed at the same time.

[0098] To sum up, because the cleaning device of this embodiment can penetrate deep into the cylindrical equipment to achieve self-cleaning, it can effectively solve the problem that the current manual cleaning methods or cleaning equipment are difficult to clean deeper cylindrical equipment; in addition, because the size of the cleaning device of this embodiment can be designed according to the size of the cylindrical equipment, it can effectively solve the problem that the current manual cleaning methods or cleaning equipment are difficult to clean or clean small cylindrical reaction equipment.

[0099] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
