Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning equipment for tobacco processing, and specifically relates to a cleaning nozzle for a heat-insulating vibrating trough. Background Technology

[0002] In the cigarette manufacturing process, the tobacco leaves undergo high-temperature and high-humidity steam treatment to expand, absorbing a large amount of moisture and significantly increasing in volume. The expanded leaves are then conveyed to a heat-insulating vibration trough, where they remain in a constant-temperature environment to achieve moisture balance and stabilization. The main function of the heat-insulating vibration trough is to provide stable temperature and uniform vibration conditions for the tobacco leaves, inhibiting excessive moisture loss and thus improving the filling value and processing resistance of the tobacco products.

[0003] However, this process also presents significant cleaning challenges. Under high temperature and humidity, the sticky components such as sugars, nicotine, and grease precipitated from the blades easily adhere to and accumulate on the entire inner surface of the insulated vibrating trough. After repeated heating and carbonization, these deposits form stubborn dirt with extremely strong adhesion. This dirt not only breeds microorganisms and contaminates products, but also affects the thermal efficiency and performance of the vibrating trough, severely restricting the continuity of production and the stability of product quality. Therefore, achieving efficient and thorough automated cleaning of the insulated vibrating trough is crucial.

[0004] Currently, cleaning methods in this field have significant limitations. Mainstream solutions often employ fixed, high-pressure nozzles, which have a single spray direction and limited water coverage. For the elongated cavity structure of the thermal insulation vibration trough, which has a bottom, ceiling, and two side facades, existing nozzles can typically only be aimed at the easily installed and sprayed bottom or a single side for rinsing.

[0005] More problematic is that, due to structural limitations, one end of the insulated vibrating trough is connected to the drive motor and is a closed end, while the other end is an open end for material entry and exit. Although the open end can be manually cleaned when the machine is stopped, the drive end and its adjacent circumferential inner walls have become "blind spots" and "dead zones" for automated cleaning due to their complex structure and limited space. Traditional nozzles cannot effectively cover the closed end and its adjacent ceiling and drive end sidewalls with high-pressure water, resulting in continuous accumulation of dirt in this area, becoming a source of hygiene hazards.

[0006] Although there are attempts to expand the cleaning range by using multiple sets of nozzles or complex moving mechanisms, these methods generally suffer from problems such as system complexity, high cost, low reliability and high energy consumption, and have failed to fundamentally solve the problem of synchronous cleaning of a closed circumferential three-dimensional space.

[0007] This application is submitted to address the aforementioned issues. Utility Model Content

[0008] To address the problems of existing cleaning solutions for thermal insulation vibratory troughs, such as single spray direction and limited water flow coverage, this utility model aims to provide a simple, comprehensive cleaning nozzle and method that can achieve efficient, continuous, and automated cleaning of at least the sealed end (vibration drive end) of the inner wall of the vibratory trough and the circumferential sidewalls, reducing manual intervention, improving equipment cleaning efficiency and production continuity, while ensuring operational safety and maintainability.

[0009] The technical solution adopted in this utility model is as follows:

[0010] The first aspect of this utility model provides a cleaning nozzle for a thermal insulation vibrating trough, the cleaning nozzle being detachably connected to an external drive water supply mechanism via its mounting pipe 1, and configured to be driven to rotate about its own axis and move axially along the thermal insulation vibrating trough, comprising:

[0011] Installation pipe 1, one end of which is connected to an external water supply mechanism;

[0012] The first connecting tube 3 has its proximal end fixedly connected to the other end of the mounting tube 1;

[0013] A nozzle structure 4 is threadedly connected to the distal end of the first connecting pipe 3 and is capable of axial movement relative to the first connecting pipe 3 during rotation; wherein, the nozzle structure 4 includes:

[0014] The second connecting pipe 403 has a proximal end threadedly connected to the first connecting pipe 3, and a plurality of first water outlets 404 are provided at the distal end along the circumferential direction.

[0015] An arc-shaped connecting plate 406 is fixedly installed at the distal end of the second connecting pipe 403 and is normally installed outside the first connecting pipe 3. The arc-shaped connecting plate 406 is provided with a plurality of second water outlets 407.

[0016] By rotating the nozzle structure 4, the second connecting pipe 403 can be driven to move axially, allowing the cleaning nozzle to switch between the following two positions:

[0017] First position: The second connecting pipe 403 moves toward the mounting pipe 1, so that the first outlet 404 retracts and is in a sealed state on the pipe wall of the first connecting pipe 3.

[0018] Second position: The second connecting pipe 403 moves away from the mounting pipe 1, so that the first outlet 404 extends out of the first connecting pipe 3 and sprays water.

[0019] Preferably, a fixing groove 2 is provided in the distal end of the first connecting pipe 3, and a second threaded portion 402 is provided on the inner wall of the fixing groove 2;

[0020] The proximal outer wall of the second connecting tube 403 is provided with a first threaded portion 401 that mates with the second threaded portion 402, so as to realize the threaded connection between the distal end of the first connecting tube 3 and the proximal end of the second connecting tube 403.

[0021] Preferably, a sealing element 405 is provided on the inner wall of the fixing groove 2 near the far end. When the nozzle structure 4 is in the first position, the sealing element 405 abuts against the outer wall of the second connecting pipe 403 to block the communication between the first water outlet 404 and the outside and form a seal.

[0022] Preferably, the second connecting pipe 403 can be sleeved inside the fixing groove 2, and the far end of the fixing groove 2 is provided with an annular notch and a sealing element 405 is embedded therein;

[0023] The sealing element 405 is a rubber sealing gasket, and its end face is provided with a guide chamfer;

[0024] The outer edge of the first outlet 404 is also provided with a rounded transition surface that matches the guide chamfer, so that when the second connecting pipe 403 rotates and moves relative to it, the first outlet 404 can smoothly slide to the closed position and form a reliable seal by means of the elastic fit between the chamfer and the sealing member 405.

[0025] Preferably, the spray centerline of the first water outlet 404 is tilted backward relative to the axis of the second connecting pipe 403, forming an angle of 100-150 degrees, so that its spray direction points to the side and rear of the cleaning nozzle.

[0026] Preferably, the second water outlet 407 is evenly distributed circumferentially along the arc surface of the arc-shaped connecting plate 406, and its spray center line faces the front and circumferentially outward of the cleaning nozzle, so as to achieve forward flushing and circumferential cleaning of the inner wall of the heat-insulating vibrating groove.

[0027] Preferably, the mounting pipe 1, the first connecting pipe 3, the second connecting pipe 403, and the arc-shaped connecting plate 406 are sequentially connected to form a continuous water flow channel, wherein:

[0028] The outlet of the installation pipe 1 is connected to the proximal flow channel of the first connecting pipe 3;

[0029] The distal fixing groove 2 of the first connecting pipe 3 is connected to the hollow inner cavity of the second connecting pipe 403;

[0030] The distal end of the second connecting pipe 403 is connected to the diversion cavity of the arc-shaped connecting plate 406, and supplies water to the first outlet 404 and the second outlet 407 respectively.

[0031] The second aspect of this utility model provides a cleaning method for a thermal insulation vibrating groove, using the cleaning nozzle described in the first aspect, comprising the following steps:

[0032] (1) Fix the cleaning nozzle to the predetermined position of the external drive water supply mechanism through the mounting pipe 1, so that the axis of the second connecting pipe 403 is aligned with the longitudinal center line of the vibrating groove;

[0033] (2) Rotate the arc-shaped connecting plate 406 to drive the nozzle structure 4 to move from the first position to the second position along the axial direction, so that the first outlet 404 and the second outlet 407 extend out of the first connecting pipe 3;

[0034] (3) Connect a high-pressure water source to the drive water supply mechanism and turn it on, so that the water flows through the installation pipe 1 and the second connecting pipe 403 in sequence, and is sprayed out from the first outlet 404 and the second outlet 407 respectively, forming a multi-directional coverage cleaning, wherein:

[0035] The first outlet 404 sprays water in a side-rear direction to cover the top and side walls of the vibrating trough;

[0036] The second outlet 407 sprays water to cover the front wall of the vibrating trough and the adjacent top and side walls in the direction of front and circumferential outward.

[0037] (4) The external water supply mechanism drives the entire cleaning nozzle to move longitudinally along the vibrating groove and rotate at the same time, so that multiple streams of water can continuously scan and clean the inner wall of the vibrating groove.

[0038] Preferably, step 3 can also be performed by opening only the second outlet 407 for spray cleaning, i.e. closing the first outlet 404, so as to achieve concentrated cleaning of the front wall of the vibrating trough and the adjacent top and circumferential sidewalls. This is suitable for scenarios where the vibrating trough outlet is open or where it is necessary to increase the spray pressure of the second outlet.

[0039] Preferably, after the cleaning operation is completed, the high-pressure water source and the drive water supply mechanism are turned off in sequence. When the drive water supply mechanism stops or is operated in reverse, the cleaning nozzle is removed from the heat-insulating vibration groove to the outside along the installation direction. Then, the arc-shaped connecting plate 406 is rotated in reverse, and the drive nozzle structure 4 is retracted axially, so that the first water outlet 404 is retracted into the first connecting pipe 3, and the connection with the external drive water supply mechanism is disconnected so as to stop use or disassemble and maintain it.

[0040] It should be noted that the cleaning nozzle protected by this utility model is a modular actuator designed for use in conjunction with an externally driven water supply mechanism. This externally driven water supply mechanism can be any integrated or separate device known in the art capable of rotation, axial movement, and supplying high-pressure water flow. This utility model does not limit the specific implementation of this externally driven mechanism, which is itself prior art and not an improvement of this utility model. The core innovation of this utility model lies in the unique retractable structure of the cleaning nozzle itself and the cleaning method it enables.

[0041] In addition, the term "near end" as used above refers to the end that is closer to the externally driven water supply mechanism, while "far end" refers to the end that is farther away from the externally driven water supply mechanism.

[0042] The advantages of this utility model over the prior art are as follows:

[0043] 1. This utility model forms a multi-directional spray combination by setting a first water outlet circumferentially on the second connecting pipe and a second water outlet on the arc-shaped connecting plate at its far end. The first water outlet covers the rear side, and the second water outlet covers the front and the outer circumference. The two sets of water outlets work together to perform three-dimensional flushing of the entire inner wall of the vibrating trough, including the traditional blind spot—the sealed end of the insulated vibrating trough and its adjacent ceiling and sidewalls, completely solving the problem of difficulty in cleaning this area due to its complex structure and limited space.

[0044] 2. This invention allows for switching between two working modes through a simple rotation operation. It can simultaneously open all outlets for full-coverage cleaning, or close the first outlet using the retractable nozzle structure, using only the second outlet for concentrated cleaning of the front wall of the vibrating trough and adjacent areas. This mode-switching function is particularly useful in scenarios where the vibrating trough outlet is open or where increased spray pressure from the second outlet is required, enhancing the method's adaptability and cleaning efficiency.

[0045] 3. This utility model integrates multiple sets of water outlets with different functions into a single nozzle assembly. A single external drive mechanism can drive it to complete complex actions such as rotation, movement, and multi-directional spraying. This avoids the problems of system complexity, high cost, low reliability, and high energy consumption associated with using multiple fixed nozzles or complex moving mechanisms. The structure is ingenious and easy to manufacture, install, and maintain.

[0046] 4. The cleaning method that is compatible with this nozzle uses an externally driven water supply mechanism to move and rotate the nozzle along the axis, so that multiple streams of water continuously scan the inner wall of the vibrating trough for cleaning. This method is highly automated, and the cleaning effect is thorough and uniform. It significantly reduces the frequency of manual cleaning intervention and labor intensity, and effectively ensures the continuity of production and the stability of tobacco product quality.

[0047] 5. This utility model innovatively adopts a threaded drive axial movement switching mechanism, realizing reliable switching between multiple working modes and integrated protection. Through the rotating nozzle structure, utilizing the transmission action of the threaded pair, the second connecting pipe and the first water outlet are driven to move axially, allowing the cleaning nozzle to flexibly switch between two functional positions, expanding its application scenarios.

[0048] First position (retracted sealing state): The second connecting pipe is moved proximally by rotation until its first circumferential outlet is completely retracted into the internal cavity of the first connecting pipe, achieving a reliable seal through the sealing element. In this state, all high-pressure water flow is concentrated and supplied to the second outlet at the far end, significantly increasing the flushing impact and coverage density on the front wall and adjacent circumferential sidewalls of the insulated vibrating trough. This mode is particularly suitable for online cleaning with the vibrating trough outlet open, or for scenarios requiring concentrated and intensive cleaning of specific areas, achieving a precise and efficient directional cleaning mode.

[0049] Second position (fully extended state): The second connecting pipe moves to the far end, so that the first water outlet fully extends out of the first connecting pipe. At this time, the first and second water outlets open simultaneously, and the water flow is split and sprayed to form a three-dimensional cleaning network covering the top, sides and front of the vibrating tank. Combined with the rotation and axial movement of the nozzles, it achieves a thorough scanning cleaning of the inner wall without dead angles.

[0050] As a preferred extension, by increasing the depth of the fixing groove and the length of the threaded connection section, the first position can also involve further retracting the nozzle structure (including the second connecting pipe and its end arc-shaped connecting plate) until it is completely contained within the first connecting pipe. This position is specifically designed for use in non-operating states or during equipment operation, providing comprehensive enclosure and physical protection for the entire nozzle's water spray components. This protects it from viscous substances in high-temperature and high-humidity environments, as well as potential impact risks from equipment vibration and maintenance operations, significantly improving the nozzle's durability and reliability while reducing maintenance requirements.

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0057] Example 1

[0058] like Figures 1 to 3 As shown, the cleaning nozzle provided in this embodiment mainly includes an installation pipe 1, a first connecting pipe 3, and a rotating nozzle structure 4. One end of the installation pipe 1 is connected to an external driving water supply mechanism via a quick connector (such as a flange), and the other end is fixedly connected to the proximal end of the first connecting pipe 3, so that the installation pipe 1 and the first connecting pipe 3 form a through water flow channel. The external driving water supply mechanism can provide rotation, axial movement, and high-pressure water flow to drive the nozzle structure and supply water.

[0059] The rotary nozzle structure 4 includes a second connecting pipe 403 and an arc-shaped connecting plate 406. The proximal end of the second connecting pipe 403 is threadedly connected to the second threaded portion 402 of the distal fixing groove 2 of the first connecting pipe 3 via a first threaded portion 401, enabling axial movement under rotary drive. Its distal end is provided with multiple first water outlets 404 circumferentially. The arc-shaped connecting plate 406 is fixed to the distal end of the second connecting pipe 403 and has multiple second water outlets 407 evenly distributed circumferentially on its arc surface. The first water outlets 404 are inclined backward by 100-150° relative to the axis of the second connecting pipe 403 to cover the rear side of the vibrating groove. The second water outlets 407 spray in the forward and circumferentially outward directions.

[0060] As a preferred embodiment, the arc-shaped connecting plate 406 can also adopt a hemispherical plate structure (such as...). Figure 1 As shown in the figure, its arc surface has a larger coverage angle, which can further increase the spray coverage range of the second water outlet 407, and achieve more uniform and efficient flushing of the front and circumferential sidewalls of the inner wall of the heat-insulating vibrating trough. This optimized solution is an optional embodiment of this utility model. When using it, the arc-shaped or hemispherical connecting plate can be flexibly selected according to the size of the vibrating trough and the cleaning requirements.

[0061] The second connecting pipe 403 can be switched between two functional positions:

[0062] First position (retracted state): By rotating the nozzle structure 4, the threaded drive causes the second connecting pipe 403 to move axially towards the mounting pipe 1, and the first outlet 404 is completely retracted into the first connecting pipe 3, forming a reliable seal with the sealing element 405. In this state, high-pressure water is concentratedly supplied to the second outlet 407, achieving concentrated cleaning of the front wall and circumferential sidewalls of the vibrating tank.

[0063] Second position (fully extended state): Rotate the nozzle structure 4 to move the second connecting pipe 403 axially away from the mounting pipe 1, and extend the first water outlet 404 out of the first connecting pipe 3, so as to work simultaneously with the second water outlet 407, forming a three-dimensional spray network covering the top, side wall and front wall, so as to achieve full coverage cleaning of the inner wall of the vibrating tank.

[0064] The inner wall of the fixed groove 2 is provided with a sealing element 405 near the far end, which is a rubber sealing gasket and has a guide chamfer on the end face; the outer edge of the first water outlet 404 is provided with a matching rounded transition surface to ensure that the first water outlet can smoothly retract and form a reliable seal during the thread rotation drive and axial movement, thereby avoiding high pressure water leakage or nozzle damage.

[0065] The installation pipe 1, the first connecting pipe 3, the second connecting pipe 403, and the arc-shaped connecting plate 406 are connected in sequence to form a through water flow channel: the outlet of the installation pipe 1 is connected to the near end flow channel of the first connecting pipe 3, the far end fixing groove 2 of the first connecting pipe 3 is connected to the hollow inner cavity of the second connecting pipe 403, and the far end of the second connecting pipe 403 is connected to the diversion cavity of the arc-shaped connecting plate 406, supplying water to the first outlet 404 and the second outlet 407 respectively, realizing multi-directional coverage spraying.

[0066] Example 2

[0067] In practical applications, the cleaning nozzle of this embodiment 1 is cleaned using the following steps to clean the heat-insulating vibrating groove:

[0068] (1) Fix the cleaning nozzle to the predetermined position of the external drive water supply mechanism through the mounting pipe 1, so that the axis of the second connecting pipe 403 is aligned with the longitudinal center line of the vibrating groove;

[0069] (2) Rotate the arc-shaped connecting plate 406 to move the nozzle structure 4 from the first position to the second position, so that the first water outlet 404 and the second water outlet 407 extend out of the first connecting pipe 3, in preparation for spray cleaning.

[0070] (3) Connect the high-pressure water source to the drive water supply mechanism and turn it on, so that the water flows through the installation pipe 1 and the second connecting pipe 403 in sequence, and sprays out from the first outlet 404 and the second outlet 407 respectively:

[0071] (4) The first outlet 404 sprays water to cover the inner wall of the vibrating trough in the direction of the side and rear, and removes the attached dirt at the sealed end and the adjacent side wall.

[0072] The second outlet 407 sprays water to cover the front wall and adjacent top and side walls of the vibrating trough in the forward and circumferential directions, thereby achieving forward and circumferential coverage and cleaning of the inner wall of the vibrating trough.

[0073] (5) The external water supply mechanism drives the entire cleaning nozzle to move longitudinally along the vibrating groove, while rotating the nozzle to achieve continuous scanning rinsing of the inner wall of the vibrating groove by multiple water streams.

[0074] (5) If the vibrating trough outlet is opened or the local jet pressure needs to be increased, the first outlet 404 can be closed and only the second outlet 407 can be opened to achieve concentrated cleaning of the front wall and adjacent circumferential sidewalls of the vibrating trough, thereby increasing the local impact force and coverage density.

[0075] (6) After the cleaning operation is completed, turn off the high-pressure water source and the drive water supply mechanism in sequence. When the drive mechanism stops or is operated in reverse, make the nozzle exit the heat insulation vibration groove to the outside along the installation direction. Then rotate the arc-shaped connecting plate 406 to drive the nozzle structure 4 to retract axially, so that the first water outlet 404 retracts into the first connecting pipe 3 and forms a seal, disconnecting the connection with the drive water supply mechanism, and completing the shutdown or disassembly maintenance operation.

[0076] Example 3

[0077] In the non-operating state, the nozzle can be further retracted, allowing the second connecting pipe and the arc-shaped connecting plate to be completely contained inside the first connecting pipe, thus sealing all water outlets for protection.

[0078] To prevent viscous substances from adhering to nozzle components in high temperature and high humidity environments;

[0079] Prevent nozzle damage caused by vibration or impact;

[0080] Improve nozzle durability and reliability, and reduce maintenance frequency.

[0081] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
