Description
Technical Field
[0001] The utility model relates to the field of cleaning of tobacco machinery and equipment, and particularly relates to a diverter cleaning device. Background Technique
[0002] Cut rag is an important component of cigarettes and plays an important role in reducing harm and tar of cigarettes and improving the filling rate of cut tobacco. The process of processing cut rag from tobacco stems includes washing tobacco stems, softening and pressing tobacco stems, cutting cut rag, adding materials to cut rag, flash puffing cut rag, and air separation of cut rag. Among them, flash puffing is a key process in the cigarette making process. Its main technological task is to dehydrate and expand the cut rag that has fully absorbed moisture according to the formula requirements and technological requirements, so as to reduce the bad smell and tar content generated during cigarette burning, and at the same time improve the filling ability of the cut rag. Flash puffing can effectively improve the quality of cut rag and reduce the harmfulness of cigarettes to the human body. The stability and reliability of the flash puffing equipment are of great significance for ensuring the quality of products.
[0003] The processing of the flash puffing equipment includes three processes: flash puffing, fluidized drying, and cooling air separation, which are respectively completed by three main machines with different technological functions independently. Among them, the first process adopts closed feeding. The cut rag to be processed is sent by a vibrating trough into the blanking cover of the flash puffing device, falls into the feeding air lock, and is sent into the expansion chamber for high-temperature heating. Through technologies such as Venturi tube blowing and gas-solid separation, the moisture contained in the cut rag is instantly evaporated, and at the same time the volume is instantly expanded. The expanded cut rag is separated from the steam by a diverter, falls into the hot air pipeline through the discharge air lock, and enters the next process. The second process adopts fluidized drying technology to make the cut rag evenly heated and quickly dried, and finally maintain a high filling value. The third process adopts fluidized cooling to conduct air separation on the cut rag to further improve the final quality of the product.
[0004] In actual production, it is found that a large amount of cut rag is easily adhered to the diverter, resulting in the problem that it is very difficult to clean the diverter. Content of the Utility Model

The utility model provides a diverter cleaning device, which can complete the efficient cleaning of the diverter, thereby ensuring the cleanliness of the environment during the production and cigarette making process, and further ensuring the product quality.
[0006] To solve the above technical problems, an embodiment of the utility model discloses a diverter cleaning device, which is characterized by including:
[0007] A water storage device, which has a cavity inside, an opening at the top, the cavity is connected to the opening, and a drain hole is provided at the lower part of the side wall of the water storage device, and the drain hole is communicated with the cavity;

When it is necessary to clean the inside of the material distributor, the operator holds the rigid pipe, aligns the water outlet end of the rigid pipe with the part of the material distributor adhered with cut tobacco, and manually opens the first control valve to eject cleaning water. The cleaning water with a certain impact force is sprayed onto the adhered cut tobacco stems, realizing the precise cleaning of the adhered cut tobacco stems, ensuring the cleanliness and hygiene of the environment during the flash expansion process, and thus ensuring the quality of the product.

By setting the control unit, receiving the signals sent by the first detection unit and the second detection unit in real time, the automatic control of the water level in the water storage device is realized.
[0017] Further, the diverter cleaning device further includes a bracket for fixing a mobile phone or a camera. The bracket is provided on the rigid pipe and is located near the water outlet end of the rigid pipe.
[0018] Further, a cross coupling is provided between the bracket and the rigid pipe. The bracket is fixed to the rigid pipe through the cross coupling, and the bracket can rotate horizontally or vertically relative to the rigid pipe.

[0021] With the above technical solution, the L-shaped rigid pipe can better adapt to the spiral structure of the diverter, and the L-shaped structure can move freely in a narrow space, which is convenient for deeply cleaning the cut tobacco adhering to the diverter.
[0022] Further, a water pipe is provided between the water inlet hole and the water source, and an electric pump is provided on the water pipe.

[0032] To make the purpose, technical solutions and advantages of the present utility model clearer, the implementation manners of the present utility model will be further described in detail below with reference to the drawings.
[0033] Flash expansion is a very crucial process in the cigarette making process. After the cut stem is flash-expanded, the fiber structure is fully expanded and the moisture is evaporated. The flash-expanded cut stem has better filling ability and taste. During the processing, the cut stem to be processed is sent from the vibrating trough to the blanking hood of the flash expansion device, falls into the feeding air lock, and is sent into the expansion chamber. At the same time, saturated steam sprays the cut stem into the venturi tube through the nozzle. The steam instantaneously compresses the cut stem and raises the temperature and humidity of the cut stem to a saturated state close to the pressure in the expansion chamber. Subsequently, the cut stem is sprayed from the venturi tube into the expansion tube. Due to the sudden drop in pressure, the moisture contained in the cut stem is instantaneously evaporated, and at the same time, the volume of the cut stem instantaneously expands. The expanded cut stem is separated from the steam by the diverter, falls into the hot air duct through the discharge air lock, and enters the next process. The residual steam is discharged through the moisture exhaust duct. However, in the specific processing process, a large amount of cut stem is easily adhered to the diverter, and it is often very difficult to clean the diverter.
[0034] Through the exploration and discovery of the inventor, in the prior art, the reason why it is very difficult to clean the diverter is that: when the cut stem passes through the diverter, it is in a state of high temperature and high humidity, and it is extremely easy to adhere to the inside of the diverter. The diverter is a spiral double-layer structure, resulting in a large amount of adhesion. In addition, the top of the inner layer of the diverter is sealed, and water can only be introduced and flushed from the bottom of the equipment upward. The space remaining between the discharge hood and the discharge vibrating trough is too narrow, and there is only a space of 200 mm high for the operator to carry out cleaning and maintenance, resulting in very difficult cleaning and it is impossible to observe whether the inside is cleaned. In the prior art, the operator must stand under the discharge hood on one side of the vibrating trough, stretch the whole arm into the discharge hood and flush with a soft water pipe. During the flushing process, the maintenance sewage flows down along the operator's arm, soaking the operator's whole body, and even often splashing sewage into the eyes. Because the flushed cut stem adheres to the cut stem containing ingredients, it will cause extremely sharp pain and swelling in the operator's eyes. After cleaning, the operator needs to hold the mobile phone and stretch it into the equipment to take pictures to check whether the inside of the diverter is thoroughly cleaned. Above, the cleaning method of the prior art has the problem that it is very difficult to clean the diverter, which seriously affects the product quality.
[0035] To solve the above technical problems, an embodiment of the present utility model discloses a diverter cleaning device. Refer to Figure 1 , the diverter cleaning device provided by this application includes a water storage device 1, a hose 4, a hard tube 3 and a first control valve 32. Among them, the water storage device 1 is internally provided with a cavity, the top is provided with an opening, the cavity is communicated with the opening, a drain hole 12 is provided at the lower part of the side wall of the water storage device 1, the drain hole 12 is communicated with the cavity, the water inlet end of the hose 4 is connected to the drain hole 12, the hard tube 3 is internally provided with a fluid passage extending through the hard tube 3 along the extension direction of the hard tube 3, the water inlet end of the hard tube 3 is connected to the water outlet end of the hose 4, and the first control valve 32 is arranged on the hard tube 3. The first control valve 32 is used to control the on-off of the fluid passage in the hard tube 3.
[0036] With the above technical solution, referring to Figure 1 , the water storage device 1, the hose 4 and the rigid pipe 3 form a complete water flow path. When it is necessary to clean the inside of the distributor, the operator holds the rigid pipe 3, aligns the water outlet end of the rigid pipe 3 with the part of the distributor where the cut tobacco adheres, and manually opens the first control valve 32 to eject cleaning water from the water storage device 1 (the water flow is shown in the direction of the arrow in the figure), so as to achieve precise cleaning of the adhered stem tobacco, ensure the cleanliness of the environment during the flash expansion process, and thus ensure the product quality. In addition, by providing the rigid pipe 3, it is convenient for the operator to extend the water outlet end of the rigid pipe 3 into the inside of the distributor and manipulate the water outlet end of the rigid pipe 3 to move in a narrow space, thereby facilitating the operator to clean.
[0037] Furthermore, referring to Figure 1 , the water storage device 1 further includes a water inlet hole 11 and a second control valve 13. The water inlet hole 11 is provided at the lower part of the side wall of the water storage device 1. The water inlet hole 11 is communicated with the cavity. The second control valve 13 is provided at the water inlet hole 11. The second control valve 13 is used to control the on-off of the water inlet hole 11.
[0038] Furthermore, the second control valve 13 is an electric valve. The distributor cleaning device further includes a detection device 2 and a control unit. The detection device 2 is used to monitor the water level in the water storage device. The detection device 2 includes a first detection unit 21 and a second detection unit 22. Both the first detection unit 21 and the second detection unit 22 are provided on the inner side wall of the water storage device 1. The first detection unit 21 is located above the second detection unit 22.
[0039] Furthermore, the control unit is electrically connected to the first detection unit 21, the second detection unit 22 and the second control valve 13 respectively; when the first detection unit 21 detects liquid, the control unit controls the second control valve 13 to close to prevent the cleaning water from overflowing from the opening at the top of the water storage device 1; when the second detection unit 22 does not detect liquid, the control unit controls the second control valve 13 to open, and the liquid enters the water storage device 1 through the water inlet hole 11 to prevent the water volume in the water storage device 1 from being insufficient.
[0040] Furthermore, the distance between the detection end of the first detection unit 21 and the opening of the water storage device 1 is 10 cm. The height of the detection end of the second detection unit 22 is higher than the drain hole 12, and the distance between the detection end of the second detection unit 22 and the bottom of the cavity of the water storage device 1 is 10 cm.
[0041] With the above technical solution, by setting the first detection unit 21 and the second detection unit 22 to monitor the water level in the water storage device 1 in real time, it is possible to prevent the water supply from being insufficient due to too low a water level or the water body from overflowing the water storage device 1 due to too high a water level, ensuring the controllability of the water level in the water storage device 1. By setting the control unit, the signals sent by the first detection unit 21 and the second detection unit 22 are received in real time, realizing the automatic control of the water level in the water storage device 1.
[0042] Further, referring to Figure 1 , the diverter cleaning device further includes a bracket for fixing a mobile phone or a camera. The bracket is provided on the rigid pipe 3 and is located near the water outlet end of the rigid pipe 3.
[0043] Further, a cross coupling is provided between the bracket and the rigid pipe 3. The bracket is fixed to the rigid pipe 3 through the cross coupling, and the bracket can rotate horizontally or vertically relative to the rigid pipe 3.
[0044] With the above technical solution, when the diverter is cleaned, the operator can install the mobile phone or the camera on the bracket, and insert one end of the rigid pipe 3 that fixes the bracket into the diverter to take pictures to check whether the diverter is completely cleaned. At the same time, by setting the cross coupling, the mobile phone or the camera can rotate horizontally or vertically on the bracket for shooting, facilitating the inspection of the cleaning condition inside the diverter from all directions and multiple angles.
[0045] Further, referring to Figure 1 , the rigid pipe 3 is L-shaped, and the L-shaped rigid pipe 3 can better adapt to the spiral structure of the diverter. When cleaning the diverter, the operator holds the L-shaped rigid pipe 3 and inserts the water outlet end of the rigid pipe 3 into the discharge cover of the diverter. The operator moves the arm back and forth, driving the rigid pipe 3 to reciprocate inside the diverter, realizing the cleaning of the adhered cut tobacco, ensuring the product quality, and at the same time avoiding the risk of safety accidents during the cleaning process in the prior art. Exemplarily, the outer diameter of the L-shaped rigid pipe 3 can be 20 mm, the inner diameter can be 16 mm, and the handheld section can be 1000 mm.
[0046] Further, a nozzle 31 is provided at the water outlet end of the rigid pipe 3. The nozzle 31 is detachably connected to the water outlet end of the rigid pipe 3. The operator can replace different nozzles 31 according to the actual situation to change the spraying state of the cleaning water. Exemplarily, the length of the nozzle can be 350 mm.
[0047] Further, referring to Figure 1 , a water pipe is provided between the water inlet hole 11 and the water source. An electric pump is provided on the water pipe, and the electric pump is electrically connected to the control unit. When the first detection unit 21 detects liquid, the control unit controls the electric pump to close. When the second detection unit 22 does not detect liquid, the control unit controls the electric pump to open.
[0048] Further, both the first detection unit 21 and the second detection unit 22 are phototubes.
[0049] With the above technical solution, when the water level in the water storage device 1 drops below 10 cm, the second detection unit 22 cannot detect the liquid. At this time, the second detection unit 22 will send a signal to the control unit. After receiving the signal sent by the second detection unit 22, the control unit controls the electric pump to start running. At this time, the second control valve 13 opens, and the water source continuously enters the water storage device 1 through the water inlet hole 11. When the water level rises to 10 cm from the open end of the water storage device 1, the first detection unit 21 can detect the liquid. At this time, the first detection unit 21 will send a signal to the control unit. After receiving the signal sent by the first detection unit 21, the control unit controls the electric pump to stop running. At this time, the second control valve 13 closes, and the water storage device 1 completes water storage.
