Technical Field
[0001] This utility model relates to the field of cigarette production technology, specifically a portable intelligent drainage device at the bottom of a tobacco conveying trough. Background Technology
[0002] In cigarette production, cleaning the tobacco conveying trough is essential. If there is no drainage device at the bottom of the trough, a large amount of water will be difficult to drain during cleaning, and water will accumulate at the bottom of the trough, affecting the cleaning effect and potentially reducing the quality of the tobacco, thus affecting the quality of the cigarettes.
[0003] However, existing drainage methods used by some enterprises still have many drawbacks: some vibrating troughs have fixed drainage outlets, which are easily clogged by tobacco shreds and dust, leading to cleaning interruptions and increasing labor costs and production burden. Furthermore, existing portable drainage devices lack liquid level monitoring and automatic control functions, relying on manual judgment for drainage, which can easily cause wastewater overflow, polluting the workshop and damaging equipment. Therefore, developing a new type of efficient and automatically controlled portable drainage device is essential to improving the cleaning efficiency and product quality of cigarette production. Utility Model Content
[0004] The purpose of this invention is to provide a portable intelligent drainage device at the bottom of the tobacco conveying trough to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable intelligent drainage device at the bottom of a tobacco conveying trough, including a drainage guiding mechanism, wherein the drainage guiding mechanism includes a water-blocking assembly plate, and the water-blocking assembly plate is equipped with an intelligent drainage control component and a drainage filtration component;
[0006] A sliding groove is provided in the middle of the front end of the water-blocking assembly plate, and a drainage guide groove is provided below the rear end of the inner side wall of the sliding groove. A drainage cover is fixedly connected to the rear end of the water-blocking assembly plate and at the opening of the drainage guide groove, and an assembly frame is fixedly connected to the front end of the water-blocking assembly plate and at the opening of the sliding groove.
[0007] The intelligent drainage control component includes a sealing baffle that is slidably connected to the inner side wall of the assembly frame and a controller that is fixedly installed on one side of the front end of the water-blocking assembly plate. A liquid level sensor is provided at the bottom of the controller.
[0008] As a further improvement of this utility model: the liquid level sensor is electrically connected to the controller via a wire, and the top of the controller is connected to the monitor via a connecting line.
[0009] As a further embodiment of this utility model: the drainage filter assembly includes a drainage funnel disposed directly below the drainage cover, a fitting groove is provided at the center of the inner bottom wall of the drainage funnel, and a drainage pipe is fixedly connected to the outer bottom end of the drainage funnel at the opening of the fitting groove.
[0010] As a further embodiment of this utility model: a filter plate is slidably assembled in the fitting assembly groove, the filter plate has a plurality of equally spaced filter holes, and two symmetrically distributed clamping grooves are provided on both sides of the upper end of the filter plate.
[0011] As a further embodiment of this utility model: a drive motor is fixedly installed at the front end of the controller, and a connecting shaft is fixedly connected to one side of the output shaft of the drive motor.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a portable intelligent drainage device at the bottom of a tobacco conveying trough, comprising a drainage guiding mechanism 1, the drainage guiding mechanism 1 including a water-blocking assembly plate 11, the water-blocking assembly plate 11 being equipped with an intelligent drainage control component 3 and a drainage filter component 2; a sliding groove 12 is provided in the middle of the front end of the water-blocking assembly plate 11, a drainage guide groove 13 is provided below the rear end of the inner side wall of the sliding groove 12, a drainage cover 15 is fixedly connected to the rear end of the water-blocking assembly plate 11 and located at the opening of the drainage guide groove 13, and an assembly frame 14 is fixedly connected to the front end of the water-blocking assembly plate 11 and located at the opening of the sliding groove 12; the intelligent drainage control component 3 includes a sealing baffle 31 slidably connected to the inner side wall of the assembly frame 14. A controller 36 is fixedly installed on one side of the front end of the water-blocking assembly plate 11. A liquid level sensor 37 is installed at the bottom of the controller 36. The liquid level sensor 37 is installed at the drainage point to monitor the water level in real time. When the water level reaches the set upper limit, the controller 36 drives the sealing baffle 31 to rise, automatically opening the drainage guide channel 13, and draining water through the drainage cover 15 to the drainage funnel 21. When the water level drops to the set lower limit, the controller 36 drives the sealing baffle 31 to fall, automatically closing the drainage guide channel 13 and stopping the drainage. At the same time, the controller 36 is connected to the monitoring device in the workshop via a connecting line 39. When the water level is abnormal, an alarm is issued in time to remind the staff to deal with it.
[0027] The liquid level sensor 37 is electrically connected to the controller 36 via a wire, and the top of the controller 36 is connected to the monitor via a connection line 39.
[0028] The drainage filter assembly 2 includes a drainage funnel 21 located directly below the drainage cover 15. The drainage funnel 21 ensures accurate sewage inflow and prevents sewage leakage. A fitting groove 22 is provided at the center of the inner bottom wall of the drainage funnel 21. A drainage pipe 24 is fixedly connected to the outer bottom end of the drainage funnel 21 at the opening of the fitting groove 22. The drainage funnel 21 can receive the water discharged from the drainage cover 15, and its drainage pipe 24 can be connected to the sewer for sewage discharge.
[0029] A filter plate 23 is slidably assembled in the fitting assembly groove 22. The filter plate 23 has several equally spaced filter holes 25 to prevent impurities from entering the drain pipe 24. Two symmetrically distributed clamping grooves 26 are provided on both sides of the upper end of the filter plate 23. The clamping grooves 26 are designed to facilitate manual removal of the filter plate 23 from the fitting assembly groove 22, which is convenient.
[0030] A drive motor 38 is fixedly installed at the front end of the controller 36. A connecting shaft 34 is fixedly connected to the output shaft on one side of the drive motor 38. The drive motor 38 and the controller 36 are connected by a wired connection. In this embodiment, the wired connection preferably uses a control bus to connect to the controller 36. The controller 36 transmits running commands through the control bus to control the operation of the drive motor 38. The drive motor 38 drives the connecting shaft 34 to rotate. The rotation of the connecting shaft 34 can drive the rack 32 that meshes with it to move, thereby realizing the lifting and lowering of the sealing baffle 31 and realizing the closing or opening of the front opening of the drainage guide groove 13.
[0031] A gear 35 is fixedly sleeved on the middle of the outer side wall of the connecting shaft 34. One end of the gear 35 meshes with a rack 32, and one end of the rack 32 is fixedly connected to the sealing baffle 31.
[0032] The front end of the water-blocking assembly plate 11 is fixedly connected to two symmetrically distributed bearing seats 33, and both connecting shafts 34 are rotatably connected to the bearing seats 33.
[0033] A water-blocking assembly plate 11 is installed at the opening of the tobacco conveying vibrating trough, and a liquid level sensor 37 is installed to monitor the water level of the tobacco conveying vibrating trough in real time. When the water level reaches the set upper limit, the controller 36 drives the sealing baffle 31 to rise, automatically opening the drainage guide channel 13. At this time, the sewage in the vibrating trough flows into the drainage cover 15 through the drainage guide channel 13, and is drained into the drainage funnel 21 through the drainage cover 15. The drainage funnel 21 receives the water discharged from the drainage cover 15. After the drainage funnel 21 receives the sewage, the sewage is filtered by the filter plate 23 to remove impurities such as tobacco and tobacco dust. The filtered sewage is then connected to the sewer through the drain pipe 24 for sewage discharge. When the water level drops to the set lower limit, the controller 36 drives the sealing baffle 31 to descend, automatically closing the drainage guide channel 13 and stopping drainage. At the same time, the controller 36 is connected to the workshop monitor via a connecting line 39. During the operation of the drainage device, the controller 36 transmits the water level information monitored by the liquid level sensor 37 and the working status of the drainage device (such as drainage on, drainage off, and the working status of the drive motor 38) to the monitor in real time. When the water level is abnormal, such as when the water level exceeds the upper limit by a large margin and cannot be lowered by drainage for a long time, or when the water level drops abnormally slowly, the monitor will receive an alarm signal and issue an alarm in a timely manner to remind the staff to handle the situation.
