Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust collection hood cleaning device and tobacco tube equipment. Background Technology

[0002] In tobacco production, tobacco tube equipment (such as loosening and rehumidifying machines, feeding machines, and flavoring machines) generates a large amount of tobacco dust during operation. Dust collection hoods are responsible for collecting the dust and purifying the production environment.

[0003] However, after prolonged operation, a large amount of dust and soot will accumulate on the inner surface of the dust collection hood, affecting dust collection efficiency, increasing the burden on subsequent dust removal systems, causing equipment failure, and endangering production safety. Current cleaning solutions for dust collection hoods rely solely on manual cleaning, which is inefficient and incomplete. Simple spray cleaning has limitations in cleaning angle and is ineffective at removing stubborn dust. Utility Model Content

[0004] One objective of this invention is to provide a dust collection hood cleaning device to solve the problems of low efficiency, incomplete cleaning, and limited cleaning angle of traditional manual cleaning and simple spray cleaning, thereby improving cleaning efficiency and cleaning effect.

[0005] Another objective of this invention is to provide tobacco tube equipment to solve problems such as dust accumulation, frequent equipment failures, and production safety hazards caused by untimely cleaning of dust collection covers in existing tobacco tube equipment, thereby improving the operating efficiency, production safety, and stability of tobacco processing quality of tobacco tube equipment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A dust collection hood cleaning device includes a dust collection hood, a spray assembly, a steam pipe, a liquid supply pipe, and a switching assembly. The dust collection hood has an inner cavity for dust collection. The steam pipe and the liquid supply pipe are both connected to a first end of the spray assembly. The steam pipe is used to transport steam, and the liquid supply pipe is used to transport high-pressure liquid. The spray assembly penetrates the wall of the dust collection hood. The second end of the spray assembly is located in the inner cavity and can spray the steam or the high-pressure liquid radially onto the surface of the inner cavity. The switching assembly is configured to enable the steam pipe or the liquid supply pipe to operate.

[0008] As an alternative, the spraying assembly includes a nozzle located at the second end of the spraying assembly. The nozzle is spherical, and the surface of the spherical nozzle is provided with a plurality of spray holes. The coverage area formed by the steam or high-pressure liquid sprayed from any of the spray holes on the surface of the inner cavity partially overlaps with the coverage area formed by the steam or high-pressure liquid sprayed from the adjacent spray hole on the surface of the inner cavity.

[0009] As an alternative, the nozzle is located at the center of the cavity.

[0010] As an alternative, the spray assembly includes a main duct, a portion of which passes through the dust collection hood and is connected to the nozzle.

[0011] As an alternative, the switching assembly includes a three-way valve that is connected to the first end of the injection assembly, the steam pipe, and the liquid supply pipe, respectively.

[0012] As an alternative, the switching assembly also includes a first check valve located at one end of the supply line near the three-way valve.

[0013] As an alternative, the switching assembly also includes a second check valve located at one end of the steam pipe near the three-way valve.

[0014] As an optional solution, the dust collection hood cleaning device also includes a first flow meter, which is installed on the steam pipe to detect the flow rate inside the steam pipe.

[0015] As an optional solution, the dust collection hood cleaning device also includes a second flow meter, which is installed on the liquid supply pipe to detect the flow rate inside the liquid supply pipe.

[0016] Tobacco tube equipment includes a tube body, a tube body cleaning device, and a dust collection hood cleaning device. The tube body cleaning device is connected to the tube body and is used to clean the inner cavity of the tube body. The tube body is connected to the dust collection hood, and the tube body cleaning device is electrically connected to the dust collection hood cleaning device.

[0017] Beneficial effects:

[0018] This invention provides a dust collection hood cleaning device. When cleaning the inner cavity of the dust collection hood, the device first connects a steam pipe and a spray component via a switching component. The spray component sprays steam to soften the dust on the inner surface of the dust collection hood, reducing its adhesion. The switching component then connects a liquid spray pipe and a spray component, spraying high-pressure liquid to thoroughly wash away the softened dust. Furthermore, the second end of the spray component sprays radially, ensuring complete coverage of the inner surface and avoiding cleaning dead zones. This dust collection hood cleaning device can reduce stubborn dust residue on the inner surface of the dust collection hood, significantly improving cleaning efficiency and effectiveness.

[0019] This utility model provides a tobacco tube equipment, in which the tube cleaning device and the dust collection hood cleaning device are electrically connected, enabling simultaneous cleaning of the tube and the dust collection hood, improving cleaning efficiency, reducing the burden on the subsequent dust removal system, lowering the failure rate of tobacco tube equipment, and ensuring a safe and stable production environment.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper" and "lower," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] This embodiment provides a tobacco tube device, which includes a tube body, a tube body cleaning device, and a dust collection hood cleaning device. The tube body cleaning device is connected to the tube body and is used to clean the inner cavity of the tube body. The tube body is connected to the dust collection hood 1, and the tube body cleaning device and the dust collection hood cleaning device are electrically connected. The electrical connection between the tube body cleaning device and the dust collection hood cleaning device enables simultaneous cleaning of the tube body and the dust collection hood 1, improving cleaning efficiency, reducing the burden on the subsequent dust removal system, lowering the failure rate of the tobacco tube device, and ensuring a safe and stable production environment.

[0030] Specifically, tobacco cylinder equipment (such as loosening and rehumidifying machines, feeding machines, flavoring machines, etc.) all include a cylinder body and a dust collection hood 1. The cylinder body cleaning device adopts existing technology, and the specific internal structure will not be described in detail here. The cylinder body is connected to the dust collection hood 1. The wastewater generated by cleaning the inner cavity 11 of the dust collection hood 1 will flow into the inner cavity of the cylinder body and be discharged together with the wastewater in the cylinder body through the discharge port of the cylinder body.

[0031] like Figure 1 As shown, the dust collection hood cleaning device includes a dust collection hood 1, a spray assembly 2, a steam pipe 3, a liquid supply pipe 4, and a switching assembly. The dust collection hood 1 has an inner cavity 11 for dust collection. The steam pipe 3 and the liquid supply pipe 4 are both connected to the first end of the spray assembly 2. The steam pipe 3 is used to transport steam, and the liquid supply pipe 4 is used to transport high-pressure liquid. The spray assembly 2 penetrates the wall of the dust collection hood 1. The second end of the spray assembly 2 is located in the inner cavity 11 and can spray steam or high-pressure liquid radially onto the surface of the inner cavity 11. The switching assembly is configured to enable the steam pipe 3 or enable the liquid supply pipe 4.

[0032] When cleaning the inner cavity 11 of the dust collection hood 1, this dust collection hood cleaning device first connects the steam pipe 3 and the spray component 2 via a switching component. The spray component 2 sprays steam to soften the dust on the surface of the inner cavity 11 of the dust collection hood 1, reducing the adhesion of the dust. The switching component then connects the liquid spray pipe and the spray component 2, spraying high-pressure liquid to thoroughly wash away the softened dust. The switching component can only connect the spray component 2 to the steam pipe 3 or to the liquid spray pipe; all three cannot be connected simultaneously. Furthermore, the second end of the spray component 2 sprays radially, fully covering the surface of the inner cavity 11 and avoiding cleaning dead spots. This dust collection hood cleaning device can reduce stubborn dust residue on the surface of the inner cavity 11 of the dust collection hood 1, significantly improving cleaning efficiency and effectiveness.

[0033] Specifically, the high-pressure liquid can be clean water or industrial cleaning agents (such as alkaline cleaning agents or neutral cleaning agents), depending on the cleaning requirements, and no specific restrictions are made here.

[0034] like Figure 1As shown, the spray assembly 2 includes a nozzle 21 located at the second end of the spray assembly 2. The nozzle 21 is spherical, and its surface has multiple spray holes 211. The coverage area formed by the steam or high-pressure liquid sprayed from any one of the spray holes 211 on the surface of the inner cavity 11 partially overlaps with the coverage area formed by the steam or high-pressure liquid sprayed from the adjacent spray hole 211 on the surface of the inner cavity 11. This partial overlap of the coverage areas of the steam or high-pressure liquid sprayed from the nozzle 21 on the surface of the inner cavity 11 ensures that there are no dead corners in the cleaning of the inner cavity 11 of the dust collection hood 1, achieving comprehensive cleaning and improving the uniformity and reliability of the cleaning.

[0035] like Figure 1 As shown, the nozzle 21 is located at the center of the inner cavity 11. When the nozzle 21 is at the center of the inner cavity 11, the distance from the nozzle 21 to each surface of the inner cavity 11 is approximately equal. This allows the sprayed steam or high-pressure liquid to cover the surface of the inner cavity 11 in a more uniform manner, avoiding situations where some areas are too close to the nozzle 21 and the spray is too concentrated, while other areas are too far away and the spray is insufficient. This ensures the uniformity of the cleaning effect, and all parts of the surface of the inner cavity 11 receive a similar degree of rinsing, reducing the problems of cleaning dead spots and inconsistent cleaning effects. In a regularly symmetrical inner cavity 11 space (such as a cuboid, cylinder, sphere, etc.), the center position is the point with equal and most balanced distances to all directional boundaries. When the nozzle 21 is in this position, it can make full use of the effective spray range, allowing the steam or high-pressure liquid to cover as many corners of the inner cavity 11 as possible, thereby expanding the overall coverage area and improving the efficiency and comprehensiveness of cleaning.

[0036] like Figure 1 As shown, the spray assembly 2 includes a main pipe 22, a portion of which passes through a dust collection hood 1 and connects to the nozzle 21. Directly connecting the main pipe 22 through the dust collection hood 1 to the nozzle 21 avoids excessive pipe bends and extensions, reducing the space occupied by the equipment and facilitating installation and maintenance. The connection between the main pipe 22 and the dust collection hood 1 allows for a stable supply of steam or high-pressure liquid to the nozzle 21. Optionally, the main pipe 22 and the wall of the dust collection hood 1 are connected by full-circle welding to ensure a tight seal. Optionally, a flange is installed at the installation position of the main pipe 22 and the dust collection hood 1, and the connection is secured with bolts. A sealing gasket (e.g., a rubber gasket) is installed between the two flanges, and the sealing gasket is sealed by the pre-tightening force of the bolts.

[0037] like Figure 1As shown, the switching assembly includes a three-way valve 51, which is connected to the first end of the injection assembly 2, the steam pipe 3, and the liquid supply pipe 4. The three-way valve 51 allows for flexible switching between steam and high-pressure liquid media within the injection assembly 2. Specifically, the steam pipe 3, the liquid supply pipe 4, and the three-way valve 51 are located outside the dust collection hood. Specifically, the three-way valve 51 is an electrically operated three-way valve. The electric actuator of the electric three-way valve controls the valve core position to achieve media flow direction switching. It also supports remote electrical signal control, precisely controlling the valve core opening and position, thereby adjusting the flow rate and direction of the media to meet the requirements of automated operation.

[0038] The switching assembly also includes a first check valve (not shown), which is located at the end of the liquid supply pipe 4 near the three-way valve 51. The first check valve effectively prevents high-pressure liquid from flowing back into the three-way valve 51 from the liquid supply pipe 4. During the operation of the spray assembly 2, when the liquid supply pipe 4 stops supplying liquid or the pressure fluctuates, the first check valve can prevent the high-pressure liquid from flowing back, avoiding the high-pressure liquid from entering the steam pipe 3 or damaging the three-way valve 51, thus ensuring the normal operation of the dust collection hood cleaning device.

[0039] The switching assembly also includes a second check valve (not shown), which is located at the end of the steam pipe 3 near the three-way valve 51. The second check valve effectively prevents steam from flowing back into the three-way valve 51 from the steam pipe 3. During the operation of the injection assembly 2, when the steam pipe 3 stops supplying steam or when pressure fluctuates, the second check valve prevents steam backflow, avoiding steam entering the liquid supply pipe 4 or damaging the three-way valve 51, thus ensuring the normal operation of the dust collection hood cleaning device.

[0040] The dust collection hood cleaning device also includes a first flow meter (not shown), which is installed on the steam pipe 3 to detect the flow rate inside the steam pipe 3. The first flow meter can provide real-time feedback of steam flow data, allowing operators to precisely adjust the steam supply and achieve accurate control of the cleaning process. The first flow meter can monitor changes in steam flow in real time; any fluctuations can be detected and adjusted promptly. The first flow meter can also monitor abnormal flow conditions within the steam pipe 3. A sudden increase or decrease in flow may indicate leaks or blockages in the steam pipe 3. Analysis of the steam flow data can promptly identify these potential problems, enabling early maintenance and repairs, preventing disruptions to cleaning operations, and extending the service life of the dust collection hood cleaning device.

[0041] The dust collection hood cleaning device also includes a second flow meter (not shown), which is installed on the liquid supply pipe 4 to detect the flow rate inside the pipe. The second flow meter provides real-time feedback of the high-pressure liquid flow rate data, allowing operators to precisely adjust the high-pressure liquid supply and achieve accurate control of the cleaning process. The second flow meter can monitor changes in the high-pressure liquid flow rate in real time; any fluctuations can be detected and adjusted promptly. The second flow meter can also monitor abnormal flow conditions within the liquid supply pipe 4. A sudden increase or decrease in flow rate may indicate leaks or blockages in the supply pipe 4. Analysis of the high-pressure liquid flow rate data allows for the timely detection of these potential problems, enabling early maintenance and repairs, preventing disruptions to cleaning operations, and extending the service life of the dust collection hood cleaning device.

[0042] Specifically, both the first and second flow meters can be either contact flow meters or non-contact flow meters. Among them, the contact flow meter can be a differential pressure flow meter, and the non-contact flow meter can be an ultrasonic flow meter.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
