Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning equipment technology, and in particular to a cleaning system and integrated cleaning rod for use in the tobacco processing industry for heat preservation vibrating troughs. Background Technology

[0002] The insulated vibrating trough is a key piece of equipment in a cigarette production line. During transport, it vibrates and spreads the tobacco shreds and maintains their temperature, effectively preventing condensation and caking. This plays a crucial role in ensuring the quality of the tobacco shreds and the sensory quality of the finished cigarettes. However, during long-term operation, grease, sugars, and fine debris from the tobacco shreds easily adhere to the warm, humid inner wall of the trough, forming stubborn, complex dirt that is difficult to remove. This buildup can not only breed microorganisms but also mix into the tobacco shreds after peeling off, causing serious product quality risks. Therefore, regular and effective cleaning of the insulated vibrating trough is a necessary step to ensure production safety and product quality.

[0003] Currently, the industry mainly uses manual cleaning or fixed automatic cleaning devices to clean insulation vibration troughs. Manual cleaning primarily involves workers entering the equipment or using hand tools through inspection ports, which suffers from low cleaning efficiency, inconsistent results, and safety hazards. Fixed automatic cleaning devices, by installing a fixed spray system inside the trough, alleviate the burden of manual operation to some extent. However, in practical applications, these fixed devices, due to the fixed installation of their spray elements, have strictly limited spray angles and coverage areas, making it difficult to adapt to the complex internal morphology of the insulation vibration trough and inevitably creating cleaning blind spots. More importantly, the piping systems of these devices are usually rigidly fixed, with a singular structure and function. This inherent design limitation makes it difficult for a single system to be compatible with and switch between various different cleaning media. Therefore, when faced with complex and firmly attached mixed dirt, existing systems are often forced to adopt a single, compromise cleaning strategy, unable to adopt the optimal media combination and action mode for different types of dirt, resulting in poor cleaning effects on stubborn mixed dirt.

[0004] This application is submitted to address the aforementioned issues. Utility Model Content

[0005] This invention aims to overcome the problems of blind spots, limited functionality, low automation, and poor sealing reliability in existing insulated vibrating trough cleaning technologies. It provides a rotating spray cleaning head that expands the coverage area through dynamic rotation, achieving thorough cleaning. An integrated cleaning rod is designed, incorporating multiple media delivery channels within a single device. The device can intelligently switch or sequentially combine media according to process requirements to specifically remove complex and stubborn dirt. A fully automated cleaning system is constructed, with unified scheduling by a control unit to achieve full automation, eliminating the need for personnel to enter the equipment and ensuring operational safety.

[0006] The technical solution adopted in this utility model is as follows:

[0007] The first aspect of this utility model provides an integrated cleaning rod for a thermal insulation vibrating groove, comprising:

[0008] Main rod 1, which has an internal cavity for accommodating it;

[0009] Rotating rod 2 is rotatably disposed coaxially within the accommodating cavity of main rod 1. An annular flow channel is formed between the inner wall of main rod 1 and the outer wall of rotating rod 2. A transmission part 204 is provided at the tail end of rotating rod 2.

[0010] The main rod 1 has multiple independent media conveying pipes 102 embedded in its pipe wall. Each group of media conveying pipes 102 has a passage interface 103 at its inlet end for connecting different cleaning media sources, and its outlet end is connected to the annular flow channel.

[0011] The first end of the rotating rod 2 is fixedly connected to the cleaning head 3. The cleaning head 3 has a distribution cavity 302 inside. The first end of the rotating rod 2 is connected to the distribution cavity 302 of the cleaning head 3. The side wall of the rotating rod 2 is provided with at least one flow channel opening 303 for connecting the annular flow channel to the distribution cavity 302 of the cleaning head 3.

[0012] The cleaning head 3 is provided with a plurality of nozzles 301 that communicate with the distribution chamber 302.

[0013] Preferably, the section of the rotating rod 2 adjacent to its head is a cavity structure 201 that communicates with the distribution cavity 302 of the cleaning head 3, and the flow channel opening 303 is disposed in the section of the cavity structure 201.

[0014] Preferably, the outlet end of the medium delivery pipe 102 extends into the interior of the annular flow channel to a section near the opening of the flow channel.

[0015] Preferably, a positioning bracket 101 is fixed in the accommodating cavity of the main rod 1, and a rotating support structure is provided on the positioning bracket 101. The rotating rod 2 passes through the rotating support structure and rotates with it. A flow channel or gap for the cleaning medium to pass through is provided on or around the positioning bracket 101.

[0016] Preferably, the number of media conveying pipes 102 is three sets, which are used to connect high-temperature steam, clean liquid and compressed gas respectively.

[0017] Preferably, the head end of the main rod 1 is closed by a detachable sealing cover 202. The sealing cover 202 has a through hole for the rotating rod 2 to pass through. A first bearing and a first rotary seal 203 are arranged sequentially from the inside to the outside in the through hole. The head end of the rotating rod 2 passes through the first bearing and the first rotary seal 203 and is rotatably connected to the sealing cover 202, so that the multiple nozzles 301 of the cleaning head 3 extend out of the head end of the main rod 1.

[0018] The tail end of the main rod 1 is provided with a tail end mounting part, the tail end of the rotating rod 2 is rotatably connected to the tail end mounting part through a second bearing, and a second rotary seal is provided between the tail end of the rotating rod 2 and the tail end mounting part.

[0019] The tail end of the rotating rod 2 extends out of the tail end mounting part and is provided with a transmission part 204. The transmission part 204 is a gear structure and is used to connect with an external drive device.

[0020] The second aspect of this utility model provides an automatic cleaning system for thermal insulation vibration grooves, comprising:

[0021] The integrated cleaning rod described in the first aspect;

[0022] A drive device, connected to the transmission part 204, is used to drive the rotating rod 2 to rotate.

[0023] The cleaning medium supply device includes a steam supply unit, a liquid supply unit, and a gas supply unit;

[0024] The control unit, which is signal-connected to the drive device and the cleaning medium supply device, is configured to: control the operation of the drive device; and control the steam supply unit, liquid supply unit and gas supply unit to supply cleaning medium to the corresponding medium delivery pipe 102 in a selected order or according to a preset timing sequence.

[0025] Preferably, the cleaning medium supply device includes pipelines connected to each medium delivery pipe 102, and control valves disposed on each pipeline; the control unit executes the cleaning sequence by controlling the opening and closing and the degree of opening of each of the control valves.

[0026] Preferably, the control unit is configured to perform the following cleaning sequence:

[0027] In the first stage, the control valve corresponding to the steam supply unit is opened to inject high-temperature steam into the heat-insulating vibrating groove;

[0028] In the second stage, the steam supply unit is shut off, the control valve corresponding to the liquid supply unit is opened, and cleaning liquid is sprayed into the heat-insulating vibrating groove.

[0029] In the third stage, the liquid supply unit is shut off, and the control valve corresponding to the gas supply unit is opened to inject compressed gas into the heat-insulating vibrating groove for purging.

[0030] The third aspect of this utility model provides a method for cleaning the heat-insulating vibrating groove of the automatic cleaning system described in the second aspect, comprising the following steps:

[0031] Step (1) Insert or extend the integrated cleaning rod into the heat-insulating vibration groove;

[0032] Step (2) Start the drive device through the control unit to make the rotating rod 2 and the cleaning head 3 rotate;

[0033] Step (3) Control the cleaning medium supply device through the control unit to supply high-temperature steam, cleaning liquid and compressed gas to the integrated cleaning rod one by one or in sequence according to the preset program;

[0034] Step (4) The cleaning medium is delivered through the integrated cleaning rod and sprayed out from the nozzle 301 of the rotating cleaning head 3 to perform composite cleaning on the inner wall of the heat-insulating vibrating groove.

[0035] The preset program is as follows: first, high-temperature steam is sprayed for a first duration, then cleaning liquid is sprayed for a second duration, and finally compressed gas is sprayed for a third duration.

[0036] The advantages of this utility model over the prior art are as follows:

[0037] 1. The rotating cleaning head of this utility model drives the nozzle to rotate, so that the cleaning medium can dynamically cover all areas of the inner wall of the heat-insulating vibration groove, including corners and complex curved surfaces that are difficult to reach by traditional fixed nozzles, eliminating cleaning blind spots and greatly improving cleaning effect and consistency.

[0038] 2. This utility model integrates a stationary external medium pipeline, a rotating transmission component, and multiple independent medium flow channels into a single cleaning rod through an innovative double-layer structure of "main rod-rotating rod". The structure is compact and saves installation space.

[0039] 3. This utility model integrates three media—high-temperature steam, clean liquid, and compressed gas—in a single rod, and can achieve rotary spraying, replacing multiple single-function traditional devices and reducing system complexity and cost.

[0040] 4. The control system of this utility model can execute a scientific cleaning sequence of "high-temperature steam softening of grease → cleaning liquid rinsing and dissolving → compressed gas blowing and drying" according to a preset program. This multi-media, sequential composite cleaning mode can exert a synergistic effect on dirt of different properties (such as the thermal softening effect of steam improving the decontamination efficiency of subsequent cleaning liquid), thereby achieving efficient and thorough removal of stubborn mixed dirt, and the cleaning process level far exceeds that of single-media cleaning.

[0041] 5. The entire cleaning process of this utility model requires no manual intervention. The control system automatically completes the forward and backward movement, rotation start and stop, and media switching of the cleaning rod. This not only greatly improves cleaning efficiency and reduces labor intensity, but also fundamentally avoids the safety risks of personnel entering confined spaces for operation, meeting the safety production requirements of modern industrial automation and intelligence.

[0042] 6. The device structure adopts a design that combines bearing support with multiple rotary seals, which ensures the stability and concentricity of the rotating rod when rotating at high speed in high and low temperature media environments. At the same time, it effectively prevents internal or external leakage of the medium in each channel under high pressure, ensuring the long-term reliability of the system.

[0043] 7. The sealing cap at the head of the main rod is designed to be detachable, which facilitates the inspection and replacement of the internal bearings and seals, reducing the cost and difficulty of later maintenance. Attached Figure Description

[0049] 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.

[0050] Example 1

[0051] like Figures 1 to 3 As shown, this embodiment provides a multi-media integrated cleaning rod for a thermal insulation vibratory trough, including a main rod 1, a rotating rod 2, and a cleaning head 3.

[0052] The main rod 1 has a hollow tubular structure with an internal cavity. Positioning brackets 101 are evenly fixed to the inner wall of the main rod 1. Each positioning bracket 101 has a central mounting hole for the rotating rod 2 to pass through, and ball bearings and a rotational support structure are embedded in the hole wall to ensure stable rotation of the rotating rod 2 within the main rod 1. Several longitudinal gaps are reserved between the positioning brackets 101 and the main rod 1 to serve as media flow channels.

[0053] Multiple sets of media conveying pipes 102 are evenly distributed along the circumference of the main rod 1. In this embodiment, three sets of media conveying pipes 102 are preferably provided, which are used to convey high-temperature steam, cleaning liquid and compressed gas respectively. Each set of media conveying pipes 102 includes two parallel and independent pipes, which are respectively connected to an external cleaning media supply unit to ensure a stable supply even when the media flow rate is large. The inlet end of each media conveying pipe 102 extends out of the tail of the main rod 1 and is reliably connected to the external media pipeline through the passage interface 103; the outlet end of each media conveying pipe 102 leads to the annular flow channel between the main rod 1 and the rotating rod 2, and preferably extends to the area near the flow channel opening 303 to shorten the path of the media into the cleaning head 3 and reduce flow loss.

[0054] The rotating rod 2 is coaxially arranged within the accommodating cavity of the main rod 1. Its first end is the output end connected to the cleaning head 3, and its tail end passes through the tail end mounting portion of the main rod 1 and is connected to the transmission part 204. The first end of the rotating rod 2 is provided with a cavity structure 201, which is connected to an annular flow channel through multiple flow channel openings 303, so that the media sent in by each media conveying pipe 102 converges into the cavity structure 201. The tail end of the rotating rod 2 is supported by a second bearing and sealed by a second rotary seal. The tail end extends outward to form the transmission part 204, which is preferably an external gear structure for meshing with the gear of an external drive motor to realize the rotation drive of the rotating rod 2.

[0055] At the head end of the main rod 1, a removable sealing cap 202 is provided. A through hole is opened in the center of the sealing cap 202, and a first bearing and a first rotary seal 203 are sequentially embedded in the through hole to ensure the sealing and stability of the rotating rod 2 under high-speed rotation and high-pressure media conditions. The head end of the rotating rod 2 passes through the sealing cap 202 and extends out of the main rod 1, and is fixedly connected to the cleaning head 3.

[0056] Preferably, the first rotary seal 203 and the second rotary seal can be rubber sealing rings or other commonly used rotary seals. Their arrangement allows them to work in conjunction with the rotating rod 2 while ensuring sealing performance, preventing media leakage and not significantly affecting the rotation of the rotating rod 2. For example, the first rotary seal 203 and the second rotary seal can be O-rings, which can be disposed on the outer surface of the rotating rod 2 and rotate with it. An annular groove can be formed on the outer surface of the rotating rod to fix the seal, thus ensuring media sealing performance without significantly affecting the rotation of the rotating rod 2.

[0057] The cleaning head 3 has a distribution cavity 302 inside, which is connected to the cavity structure 201 of the rotating rod 2. Multiple nozzles 301 are arranged circumferentially on the outer wall of the distribution cavity 302. These nozzles 301 can be distributed in a helical angle or evenly arranged in a straight line. In this embodiment, six nozzles 301 are preferably provided, with the spray direction at a certain angle to ensure that the medium forms a uniformly covering spray trajectory during rotation.

[0058] During use, the control unit activates the drive unit, engaging the drive gear with the transmission unit 204 to rotate the rotating rod 2 and the cleaning head 3. Simultaneously, the control unit selectively opens the control valves corresponding to each media delivery pipe 102 according to a preset cleaning sequence. For example, in the first stage, the steam pipeline is opened, and steam enters the annular flow channel along the media delivery pipe 102, then enters the cavity structure 201 of the rotating rod 2 through the flow channel opening 303, and is finally distributed to the nozzle 301 of the cleaning head 3 and sprayed onto the inner wall of the insulated vibrating tank, achieving thermal softening of grease and sugary dirt. In the second stage, the system switches to a cleaning liquid medium, spraying the cleaning liquid through the same flow path to flush and dissolve the softened dirt. In the third stage, the system switches to a compressed gas medium, spraying a high-speed airflow from the nozzle 301 to blow away residual droplets and debris, achieving drying and final cleaning.

[0059] In this embodiment, the cleaning process is executed automatically by the control unit. The forward and backward movement of the cleaning rod can be completed by a linear drive mechanism (such as a cylinder or electric push rod). No personnel need to enter the tank during the entire process, which significantly improves safety.

[0060] Furthermore, this embodiment can be improved in the following ways:

[0061] The number of nozzles 301 and the spray angle of the cleaning head 3 can be optimized and adjusted according to the size and shape of the tank. For example, 8-12 nozzles can be set to further improve the coverage.

[0062] The media delivery pipe 102 is not limited to three sets; a fourth or fifth set can also be added to deliver special cleaning agents or bactericides to meet different process requirements.

[0063] The materials of the sealing element 203 and the second rotary seal are preferably high-temperature resistant and corrosion-resistant fluororubber or graphite-reinforced composite materials to ensure long-term stable operation under high-temperature steam and highly corrosive cleaning fluid conditions.

[0064] The cleaning head 3 can be made into a spherical nozzle or a multi-stage flow structure as needed to improve the spray atomization effect and scouring force.

[0065] In summary, the multi-media integrated cleaning rod and its supporting system provided in this embodiment can effectively solve the problems of cleaning blind spots and stubborn dirt that are difficult to remove in the heat-insulating vibrating groove by means of rotary spraying and multi-media sequential switching, so as to achieve efficient, safe and automated cleaning operations.

[0066] 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.
