Description

Technical Field

[0001] This utility model relates to the field of tobacco processing and production technology, and in particular to a cleaning device and a tobacco expansion device. Background Technology

[0002] Tobacco expansion equipment achieves efficient expansion of tobacco materials by introducing a certain flow rate of saturated steam into a rotary connecting device, which then ejects the steam through small holes on the surface of a hollow feeder shaft and hollow pin, significantly improving the filling performance of the tobacco. However, because the process is continuously carried out under high temperature and high humidity, the surface of the feeder is prone to adhering with complex tobacco residue, mainly composed of tar, nicotine, and sugars polymerized at high temperatures.

[0003] The accumulation of these stubborn tobacco residues not only significantly reduces the heat transfer efficiency of the feeder, leading to increased steam energy consumption, but also partially or completely blocks the steam pores on the feeder surface, causing uneven steam distribution. This ultimately results in inconsistent expansion of the tobacco material, fluctuations in the product's physicochemical properties, and affects product quality stability. Furthermore, tobacco residues provide conditions for microbial growth, posing a potential food safety risk and contaminating the cleanliness of the entire production line.

[0004] Currently, cleaning of the feeder mainly relies on two methods: one is to use an automatic cleaning system for online cleaning after each batch of production, but due to limitations in the layout of the cleaning nozzles, water pressure, and insufficient flushing force, it is difficult to completely remove stubborn dirt; the other is to use manual high-pressure water gun rinsing after each day's production, which is not only labor-intensive and time-consuming, but also has many dead corners and reflection interference due to the complex curved structure and installation position of the feeder, so the cleaning effect is still not ideal. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device and a tobacco expansion device to achieve automatic cleaning of the feeder and improve the cleaning effect.

[0028] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] This embodiment provides a tobacco expansion device, including a feeder. A certain flow rate of saturated steam is introduced into the feeder and ejected through small holes on the surface of the hollow feeder shaft and hollow pin, achieving efficient expansion of the tobacco material and improving its filling performance. However, because this process is continuously under high temperature and humidity, complex tobacco residue easily adheres to the surface of the feeder. This stubborn accumulation of residue not only significantly reduces the heat transfer efficiency of the feeder, leading to increased steam energy consumption, but also partially or completely blocks the steam pores on the feeder surface, causing uneven steam distribution. Ultimately, this results in inconsistent tobacco expansion, fluctuations in product physicochemical properties, and affects product quality stability. Furthermore, tobacco residue residue provides conditions for microbial growth, posing a potential food safety risk and contaminating the cleanliness of the entire production line.

[0031] In order to clean the feeder and ensure the consistency of tobacco expansion and the stability of product quality, this embodiment also provides a cleaning device for cleaning the feeder in the above-mentioned tobacco expansion equipment.

[0032] like Figure 1 As shown, this embodiment provides a cleaning device, including a water inlet system 1, a cleaning system 2, and a drainage system 3. The water inlet system 1 includes a water inlet pipe 11 and a booster pump 12 mounted on the water inlet pipe 11. The cleaning system 2 includes an openable and closable cylinder 21 and multiple sets of cleaning components spaced apart along the inner wall of the cylinder 21. Each set of cleaning components includes multiple spaced and angle-adjustable cleaning nozzles 22. The water inlet pipe 11 is connected to the cleaning nozzles 22. The drainage system 3 is connected to the bottom of the cylinder 21 for discharging wastewater.

[0033] For example, the inlet of the water inlet pipe 11 is connected to the water source 100. A shut-off valve 13 is provided on the water inlet pipe 11. The shut-off valve 13 is used to control the opening and closing of the water inlet pipe 11. The booster pump 12 has a rated pressure of 8MPa and a flow rate of 20L / min, which provides sufficient water pressure for the cleaning nozzle 22 to improve the cleaning effect.

[0034] In one embodiment, the water inlet system 1 further includes a filter 14 disposed on the water inlet pipe 11. The filter 14 is a self-cleaning filter with a filtration accuracy of 80μm, which can intercept particulate matter in the water and prevent particulate matter in the water from being sprayed onto the feeder through the cleaning nozzle 22 and causing damage to the feeder.

[0035] The cylinder 21 consists of two axially extending semi-cylinders. One side is connected to the cylinder by a heavy-duty hinge assembly for stable and reliable rotation, while the other side uses a snap-lock 25 for quick locking and releasing. When cleaning the feeder, the operator can easily open the snap-lock 25, unscrew the cylinder 21 like a door, place the feeder inside the cylinder 21 and position it coaxially with the cylinder 21, then close the cylinder 21 and lock the snap-lock 25 to clean the feeder inside the cylinder 21 using the cleaning system 2.

[0036] The cylinder 21 is made of 304 stainless steel, and the inner wall is polished to reduce water flow resistance.

[0037] Multiple sets of cleaning components are spaced along the cylinder 21, which can fully cover the material feeder that is coaxially arranged with the cylinder 21. At the same time, the angle of the cleaning nozzle 22 can be adjusted according to the curvature of the material feeder to cover the inner curved wall of the material feeder, improve the cleaning coverage, reduce cleaning dead corners and cleaning time, realize automatic cleaning of the material feeder, and improve the cleaning effect.

[0038] In one embodiment, the inner wall of the cylinder 21 is provided with multiple flow-dividing chambers at intervals. Each flow-dividing chamber corresponds to a set of cleaning components. The cleaning nozzles 22 are connected to the flow-dividing chambers, and the water inlet pipe 11 is connected to each flow-dividing chamber through branch pipes. Each flow-dividing chamber serves as an independent pressure-stabilizing chamber and a local distributor. After the water flows into the flow-dividing chamber from the branch pipe, it fills the chamber and stabilizes the pressure, while simultaneously distributing it at equal pressure to the multiple cleaning nozzles 22 of the set of cleaning components connected to that flow-dividing chamber. This ensures that the spray pressure, flow rate, and coverage area of ​​each set of cleaning components within the cylinder 21 are basically consistent, thereby achieving uniform and thorough cleaning of the feeder without dead angles, greatly improving the cleaning quality.

[0039] For example, the flow dividers are spaced apart along the axial direction of the cylinder 21, or spaced apart circumferentially and extending axially. When the flow dividers are spaced apart axially, the flow dividers are divided into two sections, which are respectively located on the same axial section of the two half-cylinders 21. The branch pipes connect the two branch sub-pipes, and the two branch sub-pipes are respectively connected to the two flow dividers.

[0040] In this embodiment, six sets of cleaning components are provided, and six flow distribution chambers are also provided. Each set of cleaning components includes 8 to 10 cleaning nozzles 22.

[0041] In one embodiment, the cleaning nozzle 22 is rotatably mounted on the inner wall of the cylinder 21 via a ball joint assembly, and the angle adjustment range of the cleaning nozzle 22 is ±15°. The angle adjustment range of the cleaning nozzle 22 can meet the requirements of aligning the cleaning nozzle 22 with the most difficult-to-clean areas such as the curved inner wall connection of the feeder, greatly improving the cleaning coverage and thoroughness, and effectively solving the problems of stubborn stains and dead corner accumulation.

[0042] Exemplarily, the ball joint assembly includes a spherical body, a ball head seat, and a pressure cap. The tail of the cleaning nozzle 22 is machined into a spherical body, and the ball head seat is fixed to the inner wall of the cylinder 21. The ball head seat has an inner spherical cavity for accommodating and constraining the spherical body. The pressure cap is threaded to the inner wall of the cylinder 21. By tightening the pressure cap, the friction between the spherical body and the ball head seat is increased, thereby locking the spherical body after the cleaning nozzle 22 has been adjusted to the correct angle. After installation, the pressure cap is properly tightened, allowing the spherical body to rotate within the ball head seat while maintaining a temporary position due to friction. The operator can directly rotate the front end of the cleaning nozzle 22 within a conical space of ±15° using tools or by hand.

[0043] Furthermore, an O-ring is installed between the spherical body and the ball head seat to prevent water leakage. The O-ring maintains a sealed contact throughout the rotation of the spherical body.

[0044] In one embodiment, the cleaning device further includes a drive unit. A connector 23 is provided at the end of the cylinder 21, and the drive unit is motive-connected to the connector 23 to drive the cylinder 21 to rotate. When the cylinder 21 rotates, the cleaning nozzles 22 fixed to the inner wall of the cylinder 21 rotate along with it, and the spray trajectory of each cleaning nozzle 22 becomes an annular band. Continuous rotation of the cylinder 21 ensures that the feeder inside the cylinder 21 is covered multiple times and evenly by the cleaning nozzles 22, greatly eliminating cleaning blind spots. This achieves more thorough cleaning with fewer cleaning nozzles 22 and in less time, thereby reducing water consumption and energy consumption.

[0045] For example, each half-cylinder 21 has a semi-circular block at both ends. After the two half-cylinders 21 are closed, they are locked together. The two semi-circular blocks at both ends are joined to form a connector 23. The output end of the drive unit is connected to the connector 23 to drive the cylinder 21 to rotate.

[0046] In one embodiment, the driving component is a hand drill 200, and the driving end of the hand drill 200 is connected to the connector 23 via an anti-slip toothed flange 26. The hand drill 200 is a commonly used tool on the production line. Using an existing tool to drive the cylinder 21 eliminates the need for a custom-designed motor, significantly reducing manufacturing and maintenance costs. The anti-slip toothed flange 26 provides excellent torsional resistance, effectively transmitting the torque of the hand drill 200 and preventing slippage at the connection point during startup or sudden load changes, ensuring effective power transmission.

[0047] When the cylinder 21 rotates, to prevent the branch pipes from getting tangled with the cylinder 21, a rotary joint 24 is installed between the inlet pipe 11 and the branch pipes. The rotary joint 24 has a hollow shaft and is installed outside the connector 23. The rotary joint 24 has a side inlet that connects to the inlet pipe 11. The rotating end of the rotary joint 24 is connected to the connector 23 through a flange. The electric drill 200 drives the connector 23, which in turn drives the hollow shaft of the rotary joint 24, which in turn drives the entire cylinder 21 to rotate. The water entering the rotary joint 24 flows through the interior of the hollow shaft of the rotary joint 24 and is then distributed to each branch pipe.

[0048] In one embodiment, the drainage system 3 includes a drainage pipe 31 and a cyclone separator. The cyclone separator is located at the outlet of the cylinder 21 and is used to separate impurities from the wastewater. The drainage pipe 31 is used to discharge the wastewater from which the impurities have been separated. The water jet from the cleaning nozzle 22 washes the soot on the feeder and washes it off to the bottom of the cylinder 21. After flowing out of the outlet, it first enters the cyclone separator to separate solid particles from the liquid, preventing a large amount of solid particles from entering the drainage pipe 31 and causing blockage.

[0049] In one embodiment, the cyclone separator assembly includes a cyclone collection shroud 32 and a cyclone separator 33. The inlet of the cyclone collection shroud 32 is connected to the outlet of the cylinder 21, and the outlet of the cyclone collection shroud 32 is connected to the cyclone separator 33. Since the water flow from the outlet of the cylinder 21 may be intermittent or turbulent, the cyclone collection shroud 32 acts as a buffer container to stabilize the water flow, creating a stable and continuous water intake condition for the subsequent cyclone separator 33. Simultaneously, some large and heavy particles naturally settle in the cyclone collection shroud 32, serving a pre-separation function and reducing the load on the cyclone separator 33. The cyclone separator 33 can separate most of the solid particles from the wastewater. The separated water quality is greatly improved and can be pumped back to the cleaning system 2 for rinsing.

[0050] For example, the upper end of the cyclone collecting hood 32 is a cone-shaped body that is narrower at the top and wider at the bottom, and the lower end is a cylinder. The bottom of the cylinder is connected to the cyclone separator 33, which is also a cone-shaped body that is wider at the top and narrower at the bottom. The upper end of the cyclone collecting hood 32 is connected to the outlet of the cylinder 21 through the outlet pipe 34. Wastewater flowing out from the bottom of the cylinder 21 enters the upper end of the cyclone collecting hood 32 through the outlet, is guided into the cylinder through the inclined inner wall of the upper cone-shaped body, and then enters the lower cone-shaped cyclone separator 33.

[0051] In one embodiment, the hydrocyclone separator 33 includes a slag discharge port and a drain port. The slag discharge port is equipped with a slag discharge valve, and the drain port is connected to a drain pipe 31. By setting a slag discharge valve at the slag discharge port and opening the slag discharge valve periodically, the hydrocyclone separator 33 can be cleaned.

[0052] The cleaning device provided in this embodiment, when cleaning the feeder, places the feeder inside the cylinder 21, adjusts the angle of the cleaning nozzle 22, closes the cylinder 21, and locks it. The electric drill 200 is connected to the connector 23, the water inlet pipe 11 is connected to the water source 100, the shut-off valve 13 and the booster pump 12 are opened, and the pneumatic electric drill 200 drives the cylinder 21 to rotate at a speed of 200-300 r / min, causing the cleaning nozzle 22 to rotate and spray high-pressure water to clean the feeder. The cleaned dirt falls to the bottom of the cylinder 21 and enters the cyclone collection hood 32 through the water outlet pipe 34, where it is separated by the cyclone separator 33. Solid particulate filter residue is blocked, and the cleaning wastewater is discharged into the drain pipe 31.

[0053] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
