Description

Technical Field

[0001] The utility model belongs to the technical field of slag water separation and recovery, and in particular relates to a wet tobacco slag dehydration and slag discharge device. Background Art

[0002] In the tobacco processing technology, the tobacco leaves need to be cut and dried. A large amount of smoke sand and smoke dust will be generated during the cutting and drying process. At this time, a wet dust removal and purification device is needed to intercept and remove the generated smoke sand and smoke dust to prevent the accumulation of particulate matter, which will lead to the blockage of the moisture exhaust pipe of the dryer, thereby reducing the service life of the dryer and causing fire hazards. However, the liquid slag discharged by the dust removal and purification device is directly discharged into the wastewater pipe, which is easy to cause blockage.

[0003] The existing technology mainly uses manual methods to filter the slag outlet of the purification device by bagging for dehydration, but this will bring the following problems: 1. Due to the large processing capacity of the purification device, the filter bags are manually transferred to the trailer and then re-bagged for collection, which will cause a large waste of labor and dripping problems when changing bags. 2. When the bag changing speed is too slow or the bag is not changed in time, it will cause the slag outlet of the purification device to be blocked or the filter bag to leak. In summary, in the existing technology, the wet slag cannot be collected and separated. Utility Model Content

[0004] The utility model aims to provide a wet tobacco slag dehydration and slag discharge device to solve the problems of wet slag collection and separation, slag outlet blockage and dripping caused by bag change in the prior art.

[0013] Furthermore, the wet slag stacking trough is of an inverted step-shaped structure. The design of the inverted step-shaped structure can effectively prevent the goods from falling during transportation or unloading, thereby avoiding the dirty and messy conditions in the area around the platform. Enhanced unloading stability: Compared with the traditional flat-designed unloading port, the inverted step-shaped structure can better ensure the stability of the goods during flow and reduce the risk of goods hitting or falling.

[0015] Furthermore, the spiral lifter is inclined at 45 degrees, and a supporting steel frame is supported below the spiral lifter.

[0016] Furthermore, a waste slag box is placed directly below the slag outlet. The slag will be lifted to the slag outlet at the top of the spiral lifter and poured into the waste slag box for easy collection.

[0017] The technical solution of the utility model has the following beneficial effects:

[0018] 1. The technical solution of the present application can automatically lift the slag in the wet slag through the movement coordination of the spiral ribs in the spiral lifting device and the rotating drive rod, and through the inclination of the spiral lifting device, the moisture in the wet slag will be drained out due to the effect of gravity and discharged in the gap between the lifting device shells, while the slag can continue to be lifted upward, thereby effectively realizing the separation of liquid slag and avoiding the problem of pipeline blockage caused by direct slag discharge.

[0019] 2. The technical solution of the present application can automatically and continuously lift and collect the slag material, and since the shell wrapping does not cause any dripping of wet material, the time cost caused by manual bagging and the dripping problem caused by bag changing are greatly reduced.

[0027] Example:

[0028] refer to Figure 1 and Figure 2 A wet smoke slag dehydration and slag discharge device comprises a dust removal device 7, one end of which is provided with a wet slag discharge port 8;

[0029] A spiral elevator 3 is installed below the wet slag discharge port 8 to receive the wet slag and separate the moisture in the wet slag; the spiral elevator 3 comprises an elevator shell 301, a rotating drive rod 303 and a spiral fin 302, the spiral fin 302 is rotated and wound around the shaft of the rotating drive rod 303, the elevator shell 301 completely wraps the rotating drive rod 303 and the spiral fin 302, and a wet slag collection tank 1 is provided below the spiral elevator 3; a liquid discharge port 3011, a wet slag feed port 3012, a cleaning water port 3013 and a slag outlet 3014 are provided on the elevator shell 301, the liquid discharge port 3011 is set at the bottom opening of the elevator shell 301, a wet slag feed port 3012 is provided in the wet slag collection tank 1 and is connected to the inside of the elevator shell 301 and opens upward, the cleaning water port 3013 is connected to the upper front end of the elevator shell 301, and the slag outlet 3014 is set at the top of the elevator shell 301 and opens downward.

[0030] In the above scheme, when the rotary drive rod 303 rotates clockwise, the spiral ribs 302 will lift the slag in the wet slag to the top of the spiral elevator 3. When the spiral elevator 3 lifts the slag, the filtered sewage will flow to the drain port 3011 along the inside of the elevator shell 301 under the action of gravity and be discharged. The wet slag feed port 3012 is arranged in front of the drain port 3011 and is built in the drain box with it. The wet slag collection tank 1 is connected with the spiral elevator 3 through the wet slag feed port 3012. After the wet slag collection tank 1 receives the wet slag from the wet slag discharge port 8 of the dust removal equipment 7, the wet slag can be introduced into the spiral elevator 3. The cleaning water inlet 3013 is arranged at the front end of the elevator shell 301. When harmful impurities exist in the slag, liquid medicine can be introduced for deodorization or impurity removal. The slag outlet 3014 is located at the topmost part of the spiral elevator 3 and opens downward to facilitate the discharge and collection of the slag.

[0031] In a preferred embodiment, a power lifting device 6 is provided to drive the spiral lifter 3. The power lifting device 6 comprises a lifting motor 601, a gear pair 602 and a tensioning belt 603. The power lifting device 6 is arranged on the top of the rotating drive rod 303. One end of the gear pair 602 is connected to the lifting motor 601, and the other end of the gear pair 602 is connected to the rotating drive rod 303. A tensioning belt 603 is connected between the gear pairs 602 for power transmission and driving. By starting the lifting motor 601, the tensioning belt 603 synchronously drives the gear pair 602 to rotate, thereby rotating the rotating drive rod 303, and realizing the transportation of materials by the spiral ribs 302.

[0032] In a preferred embodiment, the rated voltage of the lifting motor 601 is set to 380V, the rated motor power is set to 400W, and the motor speed is set to 50r / min. This type of lifting motor 601 can ensure the normal operation of the spiral lifter 3.

[0033] refer to Figure 1 , a drainage box 2 is installed below the spiral elevator 3 to filter the spiral elevator 3 to separate the moisture in the wet slag. The drainage box 2 comprises: a drainage box shell 201, a filter residue net 202 and a sewage pipe 203. The bottom opening of the drainage box shell 201 is connected to the sewage pipe 203, and the filter residue net 202 is arranged above the sewage pipe 203 in the drainage box shell 201; a waste slag box 4 is placed directly below the slag outlet 3014.

[0034] In the above scheme, when the sewage filtered out from the spiral lifter 3 is discharged from the drain port 3011, the sewage will flow into the drain box shell 201, and the residual slag particles will be filtered out through the filter slag net 202 and then discharged through the sewage pipe 203. In addition, a waste slag box 4 is provided below the slag outlet 3014. When the spiral fins 302 transport the filtered slag to the slag outlet 3014, it can be directly discharged into the waste slag box 4 for collection.

[0035] In a preferred embodiment, the wet slag collection tank 1 is of an inverted step-shaped structure. The inverted step-shaped structure can prevent cargo from spilling: the design of the inverted step-shaped structure can effectively prevent cargo from falling during transportation or unloading, thereby avoiding the dirty and messy conditions in the area around the platform. Enhanced unloading stability: Compared with the traditional flat-designed unloading port, the inverted step-shaped structure can better ensure the stability of cargo during flow and reduce the risk of cargo collision or overturning.

[0036] In a preferred embodiment, the spiral lifter 3 is inclined at 45°, and a supporting steel frame 5 is supported below the spiral lifter 3. The 45° inclination can improve the conveying efficiency: it can more effectively utilize gravity to make the sewage flow along the inside of the lifter shell 301 to the drain port 3011 for discharge, and the slag moves upward along the spiral fins 302, thereby improving the separation efficiency of the slag and sewage. Reduce the risk of blockage: The appropriate inclination angle can help the material flow more smoothly in the spiral lifter 3, reduce the risk of blockage, and prevent the wet slag from being adsorbed on the inner wall of the spiral lifter 3.

[0037] The specific implementation process of this embodiment is as follows:

[0038] After the wet slag collection tank 1 receives the wet slag from the wet slag discharge port 8 of the dust removal device 7, the wet slag is introduced into the spiral elevator 3 for slag-water separation. The power lifting device 6 uses the lifting motor 601 to power the clockwise movement of the rotating drive rod 303 in the spiral elevator 3 through the gear pair 602 and the tensioning belt 603. The spiral ribs 302 wrapped around the rotating drive rod 303 will continuously lift the slag upward with the movement of the rotating drive rod 303. Since the spiral elevator 3 is supported by the supporting steel frame 5 and is tilted at 45 degrees, the liquid in the wet material will be drained out by gravity during the lifting process and discharged from the bottom drain port 3011 of the elevator shell 301 into the drain box 2, and the slag will be lifted to the slag outlet 3014 at the top of the spiral elevator 3 and poured into the waste slag box 4 for collection. When there are harmful impurities in the slag, liquid medicine can be introduced into the clean water outlet 3013 for deodorization or impurity removal. At this time, the wet slag can not only complete the liquid-slag separation work, but also achieve the effect of slag recovery.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
