Description

Technical Field

[0001] The utility model relates to a tobacco fermentation production line, in particular to a tobacco bacteria and enzyme liquid spraying and mixing device. Background Art

[0002] The tobacco fermentation production line is used to add fermentation liquid, such as bacterial liquid or bio-enzyme products, to the tobacco materials in the transportation process by spraying through pipes. The tobacco materials usually include tobacco leaves, tobacco shreds or tobacco stems. Since the fermentation liquid is in spray form, it can be fully mixed with the tobacco materials and then fermented in the subsequent fermentation stage.

[0003] Generally, fermentation processes are designed in dedicated fermentation vessels, and very few technologies are applied to production lines, resulting in few existing technologies that can be used as references for this technology.

[0004] The main difference is that the space in the fermentation container is fixed and the materials are processed in batches, so the entire feeding and mixing process is based on the static fermentation container.

[0005] The fermentation production line is fluid and requires the addition and mixing of materials while conveying them forward, which puts forward requirements for the design of the fermentation production line.

[0006] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0007] The utility model aims to solve the deficiencies of the prior art and thus provide a tobacco bacteria and enzyme liquid spraying and mixing device which integrates online spraying and feeding, uniform mixing and stable conveying.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a tobacco bacteria and enzyme liquid spraying and mixing device, including a material drop channel, a spraying module and a horizontal mixing and conveying mechanism;

[0009] The material dropping channel is a vertically arranged channel structure, the top end of the material dropping channel is the feeding end, and the bottom end of the material dropping channel is the discharging end and is connected to the feeding port at one end of the horizontal mixing and conveying mechanism;

[0010] The spraying module comprises a fermentation liquid feed pipe and a plurality of two-fluid nozzles distributed on the inner wall of the material-dropping channel and / or distributed in the horizontal conveying mechanism, and the spraying direction of the two-fluid nozzles is toward the inside of the material-dropping channel or the horizontal conveying mechanism;

[0011] The horizontal mixing and conveying mechanism comprises a horizontal channel, a horizontal propulsion mechanism and a stirring mechanism, and a discharge port is arranged at the other end of the horizontal mixing and conveying mechanism.

[0012] Based on the above, the material dropping channel is a cylindrical structure, and a bucket-shaped inlet is arranged at the top of the material dropping channel.

[0013] Based on the above, a transition conveyor belt is arranged above the bucket-shaped inlet, and the transition conveyor belt is used to receive the incoming materials and rotate them into the bucket-shaped inlet.

[0014] Based on the above, the two-fluid nozzles are evenly distributed inside the blanking channel along the circumferential direction, and the two-fluid nozzles are provided with at least one layer from top to bottom.

[0015] Based on the above, the two-fluid nozzles are grouped and arranged in the front and rear halves of the horizontal conveying mechanism.

[0016] Based on the above, the horizontal mixing and conveying mechanism is a screw conveyor, the outer shell of the screw conveyor is the horizontal channel, and the auger of the screw conveyor is a complex of the horizontal propulsion mechanism and the stirring mechanism.

[0017] Based on the above, the horizontal mixing and conveying mechanism is a complex of a screw conveyor and a stirring blade, and the front half and / or the rear half of the horizontal mixing and conveying mechanism is a screw conveyor to constitute one of the complexes of the horizontal propulsion mechanism and the stirring mechanism; a plurality of stirring blades are distributed on the middle section transmission shaft of the horizontal mixing and conveying mechanism, and a part of the stirring blades are inclined toward the outlet direction to provide driving force to constitute the second complex of the horizontal propulsion mechanism and the stirring mechanism.

[0018] Based on the above, another part of the stirring blade is perpendicular to the transmission shaft.

[0019] Based on the above, the inclination direction of another part of the stirring blades is toward the inlet direction, and the total number of the stirring blades inclined toward the outlet direction is greater than the total number of the stirring blades inclined toward the inlet direction.

[0020] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0021] The material dropping channel is used in conjunction with the spraying module to spray the fermentation liquid on the tobacco material while conveying the material. Then, the horizontal propulsion mechanism and the stirring mechanism in the horizontal mixing and conveying mechanism are used to horizontally convey the tobacco material while mixing it, so that the material obtained by the downstream equipment is finally fully mixed with the fermentation liquid.

[0022] The horizontal mixing and conveying mechanism can adopt a screw conveyor or a combination of a screw conveyor and a stirring blade to enhance the mixing ability.

[0023] The flow rate of the bacteria and enzyme liquid can be adjusted by a valve, the atomization effect of the two-fluid nozzle in the spray module is adjustable, and the conveying speed of the horizontal mixing and conveying mechanism is adjustable, so that the device has good adjustability and can be applied to the fermentation of most tobacco products.

[0029] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0030] Example 1

[0031] like Figure 1 As shown, a tobacco bacteria and enzyme liquid spraying and mixing device includes a material drop channel 1, a spraying module 2 and a horizontal mixing and conveying mechanism 3.

[0032] The material dropping channel 1 is a vertically arranged channel structure. In the present embodiment, the material dropping channel is a cylindrical structure. The top end of the material dropping channel 1 is the feed end, which is usually designed as a bucket-shaped inlet to facilitate the material dropping of the upstream conveyor belt. The bottom end of the material dropping channel is the discharge end and is connected to the feed port at one end of the horizontal mixing and conveying mechanism 3.

[0033] In this embodiment, the spraying module 2 includes a fermentation liquid feed pipeline 21 and a plurality of two-fluid nozzles 22 distributed on the inner wall of the material drop channel 1. The spraying direction of the two-fluid nozzle 22 is toward the inside of the material drop channel 1. The two-fluid nozzles are evenly distributed along the circumference. The two-fluid nozzles are arranged in several layers from top to bottom to improve the spraying uniformity and efficiency.

[0034] The horizontal mixing and conveying mechanism 3 comprises a horizontal channel 31, a horizontal propulsion mechanism and a stirring mechanism. A discharge port is arranged at the other end of the horizontal mixing and conveying mechanism.

[0035] In this embodiment, the horizontal mixing and conveying mechanism is a screw conveyor, the outer shell of the screw conveyor is the horizontal channel 31, and the auger 32 of the screw conveyor is a complex of the horizontal propulsion mechanism and the stirring mechanism.

[0036] Working principle:

[0037] The upstream conveyor belt conveys the tobacco material to the drop channel 1, and the tobacco material falls into the drop channel 1 under the action of its own gravity. During the falling process, a number of two-fluid nozzles 22 in the spray module 2 spray fermentation liquid on the tobacco material, and the fermentation liquid is mostly concentrated in the peripheral tobacco material. Then the tobacco material enters the horizontal mixing and conveying mechanism 3 below.

[0038] While the screw conveyor in the horizontal mixing and conveying mechanism 3 pushes the tobacco material forward, due to the dispersion of the tobacco material itself, it will move relative to each other under the action of its own driving force, similar to the effect of stirring action, and stirring is achieved while feeding, so that the fermentation liquid is fully mixed with the tobacco material, and then discharged from the discharge port, realizing the dynamic filling of fermentation liquid and mixing process of the tobacco material on the production line.

[0039] Example 2

[0040] like Figure 2 As shown, the main difference between this embodiment and embodiment 1 is that: the horizontal mixing and conveying mechanism is a complex of a screw conveyor and a stirring blade, and the front half and / or the rear half of the horizontal mixing and conveying mechanism is a screw conveyor to constitute one of the complexes 33 of the horizontal propulsion mechanism and the stirring mechanism; a plurality of stirring blades are distributed on the middle section transmission shaft of the horizontal mixing and conveying mechanism, and a part of the stirring blades are inclined toward the outlet direction to provide driving force to constitute the second complex 34 of the horizontal propulsion mechanism and the stirring mechanism.

[0041] The advantage of this embodiment is that the stirring blades in the middle section have higher stirring efficiency and better mixing effect. Compared with the screw conveyor, it can fully stir the materials and improve the mixing rate.

[0042] In this embodiment, another part of the stirring blades is perpendicular to the transmission shaft to help enhance the stirring efficiency.

[0043] In a preferred embodiment, the inclination direction of another part of the stirring blades is toward the inlet direction, and the total number of stirring blades inclined toward the outlet direction is greater than the total number of stirring blades inclined toward the inlet direction. The purpose is to allow the stirring blades to move toward the discharge port as a whole while achieving reciprocating motion over a shorter distance, thereby improving the stirring efficiency.

[0044] Example 3

[0045] like Figure 3 As shown, the two-fluid nozzles are arranged in the horizontal conveying mechanism, specifically in the front and rear sections of the horizontal conveying mechanism. The spraying direction of the two-fluid nozzles is toward the inside of the horizontal conveying mechanism.

[0046] The specific position of the two-fluid nozzle can be in the material dropping channel, or in the horizontal mixing and conveying mechanism, or both.

[0047] In a preferred embodiment, different from Embodiment 1, Figure 4 As shown, since the loading angle of the original loading conveyor belt is too large when loading materials in a small space, the falling materials are not easy to enter the falling channel. Therefore, in a preferred embodiment, a transition conveyor belt is arranged above the bucket-shaped inlet, and the transition conveyor belt is used to receive the falling materials at the end of the loading conveyor belt and rotate them into the bucket-shaped inlet.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
