The material is driven by stirring vane and stirs after getting into the stirred tank, and when the material pile up to being higher than stirred tank opening border in the stirred tank, the material then can overflow and pass through the blanking passageway blanking downwards, and then gets into second feed inlet of second conveying mechanism through agitated vessel bottom stirring material outlet. Through this mode stirring and unloading, can realize stirring ejection of compact simultaneously, improve production efficiency. And for stirring by utilizing the cavity in the whole stirring equipment, the stirring tank with a smaller containing cavity is more beneficial to stirring uniformly, and the required stirring power is also less.

Since the water component is required to be provided in the mixing and fermenting processes, the water component is required to be transported in the conveying process before fermentation, and the first conveying mechanism which is carried in front of the stirring equipment or the fermenting equipment is different from the conveying belt and can convey the water in the closed shell, the first conveying mechanism is arranged as a direct upstream conveying mechanism of the second conveying mechanism, so that the perfect conveying of the water component is facilitated. And other raw and auxiliary materials are mostly piled particulate matters, and the particulate matters can be transported by adopting various structures, including a closed conveyor mechanism. Compared with the mode of driving the whole helical blade to convey, the conveyor belt conveying mode requires less power, can effectively save energy consumption and reduce cost. Meanwhile, the dust and waste gas leakage prevention device has the technical effect of ensuring that dust, waste gas and the like do not leak. And the closed conveying belt mechanism is arranged in front of the first conveying mechanism, so that the requirements on the conveying distance and the length of the first conveying mechanism are reduced, and the load on a single conveying structure is reduced.

Since the raw and auxiliary materials are generally in the form of accumulated particles, they may roll and fall out of the conveyor belt, and particularly when the conveyor belt vibrates up and down due to the accuracy of mechanical equipment, the raw and auxiliary materials are more likely to roll and fall out of both ends in the width direction. The cross section of the third conveyor belt in the direction perpendicular to the conveying direction is arc-shaped, namely, the two sides are high and the middle is low, materials are concentrated in the middle area of the conveyor belt after entering the surface of the third conveyor belt, and even if the materials exist in the form of particles, the materials are difficult to roll towards the two sides and fall off, so that the loss of the materials in the conveying process is reduced, the precision of production control is improved, and the production effect is further improved.

Further, the closed conveyor belt mechanism comprises a closed third shell, a conveyor belt, a first synchronous wheel, a second synchronous wheel and a third synchronous wheel; the two ends of the third shell are respectively provided with a third feeding hole and a third discharging hole, the third discharging hole is connected to the first feeding hole, an arc-shaped hole with an upward arc-shaped opening is arranged on the end face of one end of the third shell, which is close to the third feeding hole, and an outlet hole is arranged on the bottom surface, which is close to one side of the third discharging hole; the first synchronous wheel is arranged outside the third shell, at one side of the arc-shaped hole and the top end of the first synchronous wheel is higher than the arc-shaped hole; the second synchronous wheel is arranged at one side of the third shell close to the third discharge hole and is a saddle wheel; the third synchronizing wheel is arranged outside the third shell, the bottom end of the third synchronizing wheel is lower than the third shell, and the conveyor belt sequentially passes through the first synchronizing wheel, the arc-shaped hole, the second synchronizing wheel, the outlet hole, the third synchronizing wheel and the first synchronizing wheel.

Further, the closed conveyor belt mechanism comprises a closed third shell, a third conveyor belt, a first synchronous wheel, a second synchronous wheel and a third synchronous wheel; the two ends of the third shell are respectively provided with a third feeding hole and a third discharging hole, the third discharging hole is connected to the first feeding hole, an arc-shaped hole with an upward arc-shaped opening is arranged on the end face of one end of the third shell, which is close to the third feeding hole, and an outlet hole is arranged on the bottom surface, which is close to one side of the third discharging hole; the first synchronous wheel is arranged outside the third shell, at one side of the arc-shaped hole and the top end of the first synchronous wheel is higher than the arc-shaped hole; the second synchronous wheel is arranged at one side of the third shell close to the third discharge hole and is a saddle wheel; the third synchronizing wheel is arranged outside the third shell, the bottom end of the third synchronizing wheel is lower than the third shell, and the third conveyor belt sequentially passes through the first synchronizing wheel, the arc-shaped hole, the second synchronizing wheel, the outlet hole, the third synchronizing wheel and the first synchronizing wheel.

Because the raw materials and the auxiliary materials generally exist in the form of piled particles, the raw materials and the auxiliary materials can roll and fall out of the third conveying belt, and the arc-shaped holes and the saddle wheels are arranged, so that the cross section of the third conveying belt in the direction perpendicular to the conveying direction can be matched to be in an arc shape, namely, the two sides are high and the middle is low, the materials are concentrated in the middle area of the conveying belt after entering the surface of the conveying belt, and even if the materials exist in the form of piled particles, the materials are difficult to roll and fall out towards the two sides, thereby reducing the loss of the materials in the conveying process, improving the precision of production control and further improving the production effect. The top end of the first synchronous wheel is higher than the arc-shaped hole, so that the arc-shaped hole is propped against the surface of the conveyor belt, and the third conveyor belt is attached to the arc-shaped hole and forms a state with an arc-shaped section. And the third synchronizing wheel is arranged as a saddle wheel, so that the shape of a conveying belt before discharging is maintained, and the materials are prevented from falling in the process of feeding to discharging. The arrangement of the outlet opening closer to the first synchronizing wheel than to the third synchronizing wheel is convenient for the third discharge opening, i.e. only the third discharge opening is arranged on one side of the third synchronizing wheel, and the outlet slot can guide the third conveyor belt passing through the third synchronizing wheel to move towards the opposite side. The second synchronous wheel is arranged, so that the conveyor belt is prevented from being propped against the shell, and the abrasion of the surface of the conveyor belt is reduced.

Further, the arc hole edge is provided with a plurality of balls, and the outlet hole edge is provided with a plurality of balls. The arrangement of the balls is beneficial to reducing the abrasion of the third conveyor belt passing through the arc-shaped holes and the outlet holes, and the third conveyor belt can not generate resistance to movement basically, so that smooth transmission is facilitated.

Further, the third shell is connected with a negative pressure device which is communicated with the inner cavity of the third shell and the outdoor environment. Because the third conveyor belt needs to move continuously, the arc-shaped holes and the outlet holes of the third conveyor belt need to reserve the space needed by the sliding of the conveyor belt, the third shell of the closed conveyor belt mechanism may not be completely closed, but the negative pressure state in the third shell can be maintained all the time by arranging the negative pressure device, so that dust and waste gas in the closed conveyor belt mechanism are discharged outside or collected.

Further, the device also comprises more than one fourth conveying mechanism which is arranged at the upstream of the closed conveying belt mechanism and used for sealing and bearing, wherein the fourth conveying mechanism comprises a closed fourth shell and a helical blade which is arranged in the fourth shell and driven to helically convey materials, and a fourth feed inlet and a fourth discharge outlet are arranged on the fourth shell; or the fourth conveying mechanism comprises a closed fourth shell and a plurality of scraping plates which are arranged in the shell and driven to move and convey materials, and a fourth feed port and a fourth discharge port are formed in the fourth shell; or, fourth conveying mechanism includes closed fourth casing, fourth conveyer belt, the fourth casing is equipped with fourth feed inlet, fourth discharge gate, the shape is the ascending arc of opening on the cross-section of perpendicular to direction of transfer of fourth conveyer belt, and the material passes through fourth feed inlet, fourth conveyer belt in proper order and reaches fourth discharge gate.

Through setting up the more than one fourth conveying mechanism who accepts in closed conveyer belt mechanism upstream, can realize long distance transmission equally, further separate the same transportation distance for a plurality of short transportation distances, be favorable to using first conveying mechanism or closed conveyer belt structure etc. that the conveying distance is shorter, make overall structure more easy replacement, maintenance. For the single first conveying mechanism with longer conveying distance, the spiral blade has heavier load on the driving part, and the conveying effect and the stirring effect are limited. For a closed conveyor mechanism with a longer conveying distance, when the conveying distance is longer, the middle part of the conveyor belt is easy to sink, and besides the conveying effect is influenced, the conveyor belt is also more easy to damage and cannot be used continuously. The same long-distance transmission is realized through the connection of the plurality of transmission mechanisms, so that the arrangement of the transmission mechanisms is facilitated, the maintenance and replacement of the whole transmission mechanism are facilitated, and the loss of each transmission mechanism can be effectively reduced due to the short transmission distance.

Further, the device comprises a collecting and maintaining device, the collecting and maintaining device comprises a collecting cavity, a maintaining door is arranged on one side of the collecting cavity, the feeding port side of the second conveying mechanism is borne in the collecting cavity, and a drain hole is formed in the bottom end of the feeding port side of the second conveying mechanism. The maintenance door is a door structure arranged on the side wall of the collecting cavity, and maintenance personnel can open the maintenance door so as to maintain and clean the drain hole and the collecting cavity conveniently. Since the scraper is generally effective in transporting water unlike a helical blade, some of the transported water cannot be transported further and is deposited on the lower side of the second transporting mechanism. If the deposition is continued, the entry and the transmission of subsequent materials are not facilitated, the timely discharge is facilitated through the drain hole, or the deposited water is independently and continuously transported, so that the influence on the transmission effect caused by the continuous deposition of the deposited water and other raw materials in a single container is avoided.

Further, a recoil pump for dredging the drain hole is arranged on the drain hole side of the second conveying mechanism. Because the nicotine raw and auxiliary materials and water are mixed to form larger caking, the blocking of the drain hole is easy to be caused in the drainage process, and the drain hole can be dredged through the recoil pump. Specifically, the drain hole is connected with a branch pipeline, one branch is used for draining water, the other branch is communicated with the drain hole and the recoil pump, when the recoil pump is needed to be used, the branch used for draining water is closed, the recoil pump and the corresponding branch of the recoil pump are started, and then the drain hole can be recoiled, so that the drain hole is dredged. Specifically, the recoil pump is a pneumatic pump that provides a high pressure air flow.

Further, the first conveying mechanism is obliquely arranged, and the first discharge port end is lower than the first feed port end. When the first conveying mechanism is used for conveying the water component, if the first conveying mechanism is horizontally arranged, the water component can also partially flow to the side opposite to the conveying direction due to unidirectional transportation of the spiral blade which is not completely closed, and adhesion with other raw materials and auxiliary materials is easily caused to influence the efficiency of subsequent conveying. When the water pump is obliquely arranged, water does not need to be considered to move to the opposite side, and the water component can wash the raw and auxiliary materials at the downstream to continuously move along the conveying direction.

Further, when the first conveying mechanism is obliquely arranged, the included angle between the first conveying mechanism and the horizontal plane is 5-15 degrees. The first conveying mechanism is arranged to have a certain inclination angle, so that the water can be prevented from moving in the opposite direction to the conveying direction, and the stirring effect of the original spiral conveying is conveniently maintained. If the inclination angle is too large, the material moves faster under the action of gravity, and the stirring effect of the spiral blade is weakened, so that a certain angle needs to be maintained to keep the advantages of the spiral blade.

Further, the upper part of the fermentation equipment is also provided with a negative pressure exhaust mechanism communicated with the outside. The fermentation process comprises an aging/alkalizing process, and in the process, waste gas is generated, so that the waste gas generated in the fermentation tank can be discharged in time by arranging a negative pressure exhaust mechanism. Further, the negative pressure exhaust mechanism comprises a pipeline communicated with the outdoor environment and a negative pressure fan arranged in the pipeline.

Through setting up transmission environment relatively confined first conveying mechanism, second conveying mechanism, fermentation equipment for before the fermentation, the fermentation in-process all keep comparatively confined environment, effectively prevent the scattering of dust, waste gas in the production process, thereby keep clean, friendly workshop environment, avoid producing health problem to workshop staff. Meanwhile, on the premise of ensuring that dust and waste gas are not scattered, the invention adopts a spiral conveying mode and can provide a certain stirring effect, and even if special stirring equipment is not used, the invention can realize a basic stirring function by utilizing the first conveying mechanism and realize multiple purposes. The second conveying mechanism for conveying wet materials is also designed to convey the wet materials to a scraper so as to provide enough conveying power and stability in consideration of the characteristics of agglomeration and density of the wet materials. On this basic scheme, this application can also be through setting up a plurality of transport mechanism in order to realize long distance's transmission through a plurality of transport mechanism cooperation at first transport mechanism upstream, avoids alone first transport mechanism transmission distance overlength and takes place to damage or arouses transmission efficiency's reduction. The closed conveying belt mechanism is arranged at the upstream of the first conveying mechanism, so that the closed conveying belt mechanism has the advantages of conveying efficiency, long-distance conveying realized by matching, and meanwhile, the power required by conveying can be reduced. The whole can carry out multiple combination at first transport mechanism upstream to adapt to different production demands, the maneuverability is strong, the maintenance of being convenient for, replacement, also more stable. This application is still through setting up agitated vessel in order to further improve the mixing effect, further gets rid of inclined, vertical transmission through collecting device and probably brings adverse effect, ensures that second conveying mechanism continuously carries the material smoothly, improves holistic conveying efficiency. The stirring tank, the negative pressure device and other structures are arranged to improve the stirring and sealing transmission effects, so that the production efficiency, the production quality and the like are further improved.

Further, a waste residue treatment device is connected to the downstream of the waste residue outlet of the nicotine production raw material, the waste residue treatment device comprises a return conveying device, a material storage tank and a movable collection device, the return conveying device receives waste residues and conveys the waste residues into the material storage tank and/or the waste residues are reserved on the return conveying device after passing through the material storage tank, an opening and closing door is arranged at the bottom of the material storage tank, and the opening and closing door releases the waste residues in the material storage tank after the movable collection device is positioned under the opening and closing door.

Further, the mobile collection device is a collection vehicle.

The return conveying device comprises a conveying device with a closed loop conveying path. Further, the waste residue recycling device is formed by a plurality of mutually-connected conveying devices, when waste residue cannot enter the storage tank, the waste residue recycling device continuously conveys the waste residue to the original waste residue receiving position after receiving the waste residue, and continuously conveys the waste residue in a next cycle until the storage tank is filled with filling space, and the waste residue is filled in the next cycle conveying process after passing through the storage tank. The opening and closing door is a horizontally placed opening and closing door which is driven to open and close so as to open or close the outlet at the bottom of the storage tank.

After the return conveying device receives the waste residues, conveying the waste residues, filling the waste residues into the storage tank when the waste residues pass through the storage tank, and/or keeping the waste residues on the return conveying device for continuous transmission, when the storage tank is in an unfilled complete state, the waste residues enter the storage tank, if the storage tank is completely filled in the entering process, the residual unfilled waste residues continuously enter the return conveying device, and filling the storage tank when the waste residues are filled next time; when the storage tank is in a full filling state, waste residues are directly conveyed through the storage tank by the return conveying device and are reserved on the return conveying device, and the waste residues are filled in at the next filling time. And an opening and closing door is arranged at the bottom of the storage tank, and when the movable collection equipment is in place, waste residues in the storage tank are released. Through the nicotine production waste residue automatic processing system in this application, the waste residue need not concentrate on a certain place and piles up, and the upper surface of whole conveyer is equivalent to a plurality of positions of stacking, and the space in make full use of transverse direction. More importantly, the automatic circulation flow and treatment of the waste residues can be realized through the cooperation of the return conveying device and the storage tank, manual monitoring is not needed, the pipeline and the baffle are conveniently arranged on the whole system, a fully-closed automatic treatment system is formed, and the waste residues are only exposed when the waste residues are released after the movable collecting equipment is in place. Not only does not need manual monitoring and vacates the position of piling up the waste residue in time, but also is convenient for forming a closed structure to prevent the influence of harmful gas in the waste residue on human body.

Further, still include waste residue entering detector, passback conveyer transmission speed controller, waste residue entering detector detects whether there is waste residue about to fall into passback conveyer device, and it has a plurality of gravity sensors to distribute on the passback conveyer, transmission speed controller is according to gravity sensor, waste residue entering detector signal control passback conveyer transmission speed to make the empty region cooperation in surface receive the waste residue about to get into.

Further, a discharging pipeline is arranged below the storage tank, the discharging pipeline comprises an upper conical opening and a lower conical opening connected with the upper conical opening, and waste residues in the storage tank are discharged through the opening and closing door, the upper conical opening and the lower conical opening in sequence. The discharging pipeline is arranged below the storage tank, so that the discharging of waste residues can be guided, the waste residues can be scattered and fall down due to the fact that the opening and closing door directly releases the waste residues, the waste residues cannot be concentrated in a fixed area, and collection of a collection vehicle is not facilitated. The upper cone opening is arranged on the upper part of the discharge pipeline, so that waste residues can enter the treatment management rapidly, the lower cone opening is arranged at the bottom, so that the waste residues are guided and limited to fall on a fixed area, and a larger discharge outlet is provided and falls on the fixed area with a larger area.

Further, the cross section of the discharging pipeline is elliptical. At present, in order to fully collect materials, the movable collection equipment with the hoppers is arranged, such as a collection vehicle, and the hoppers are generally cuboid spaces, and elliptical shapes are arranged, so that waste residues can be piled up in the longitudinal direction and the transverse direction of the hoppers, and the collection space of the hoppers is fully utilized. Moreover, when the inner wall of the discharging pipeline is a smooth cambered surface, residues at corners can be effectively avoided, and the residues can smoothly slide down and enter the collecting space.

Further, the discharging pipeline is sleeved with an elastic locating sleeve, and the bottom end of the locating sleeve is lower than the bottom end of the lower cone opening. The bottom of the discharging pipeline is provided with a lower cone, waste residues are likely to be scattered outside the movable collecting equipment provided with the receiving hopper by directly discharging the waste residues through the lower cone, and when the elastic locating sleeve is arranged and the bottom end of the locating sleeve is lower than the bottom end of the lower cone, the part of the locating sleeve exceeding the bottom end of the lower cone is close to the middle due to certain elasticity of the locating sleeve, so that the situation that the waste residues are scattered aside when directly falling through the lower cone is avoided. Meanwhile, due to certain elasticity, when waste residues pass through the positioning sleeve under the lower cone opening, the positioning sleeve can still be stressed and changed to enable the waste residues to fall smoothly. The advantage on the lower cone opening blanking area is ensured on the one hand through the locating sleeve outside the lower cone opening, and the problem of sprinkling caused by the fact that the lower cone opening is large when the movable collecting device is not completely aligned with the collecting position is avoided on the other hand.

Further, the movable collection device comprises a movable body and a receiving hopper arranged on the movable body, and the bottom end of the positioning sleeve is lower than the edge of an opening of the receiving hopper. Further, the movable collecting device is a collecting vehicle, namely the collecting vehicle comprises a vehicle body and a receiving hopper arranged on the vehicle body, and the bottom end of the positioning sleeve is lower than the opening edge of the receiving hopper. The bottom end of the positioning sleeve is lower than the edge of the opening of the receiving hopper, so that the positioning sleeve can be matched with the receiving hopper to centralize waste residues in the receiving hopper. When the collecting hopper of the collecting vehicle is completely right to the opening and closing door and the discharging pipeline of the storage tank above, the collecting hopper is at the optimal collecting position, and natural discharging can accurately fall on the collecting hopper. However, the collecting vehicle is limited by factors such as precision or control of the collecting vehicle, the collecting vehicle is not in the optimal collecting position, and the collecting hopper is positioned below the discharging pipeline, but the position deviation possibly exists, and at the moment, the positioning sleeve is only required to be positioned in the collecting hopper through the cooperation of the positioning sleeve and the collecting hopper, so that waste residues can still fall into the collecting hopper, and the waste residues cannot be scattered outside the collecting hopper.

Furthermore, the lower end of the positioning sleeve is a contraction opening which is close to the middle, and the contraction opening is outwards opened after being stressed. At this time, compared with the locating sleeve with a larger opening, the collecting vehicle can at least realize the alignment process only by being parked below the shrinkage opening with a smaller caliber, and the alignment difficulty of the collecting vehicle and the waste residue outlet is reduced. Furthermore, when the waste residues do not fall, the shrinkage opening is in a shrinkage state, and is in a bundle-shaped structure relative to the collection vehicle, so that the collection vehicle is aligned; when the waste slag falls down, the shrinkage port does not release the waste slag in time, and the waste slag can be accumulated on the shrinkage port and continuously presses two sides of the shrinkage port along with the falling of the subsequent waste slag, so that the shrinkage port is opened and the waste slag is quickly released. The balance of convenient collection, accurate collection and quick release of waste residues is realized through the shrinkage opening.

Further, a lifting device is arranged on one side, close to the upper conical opening, of the positioning sleeve, and the lifting device is used for lifting the positioning sleeve upwards to shorten the downward extending distance of the positioning sleeve relative to the bottom end of the lower conical opening. When the bottom end height of the locating sleeve is unchanged, the waste residues are accumulated on the collecting vehicle until the height reaches the bottom end height of the locating sleeve, the waste residues falling subsequently are easily limited in the locating sleeve and cannot be discharged out of the locating sleeve, and the waste residues cannot be discharged fully and the collecting vehicle space cannot be fully utilized because the collecting vehicle is not continuously filled in the surrounding low-position space in the collecting space. Moreover, the collection vehicle is not convenient to transport away. Because the waste residue in the locating sleeve can not flow out continuously, the collecting vehicle drives to be separated from the locating sleeve, and the waste residue can fall on an area outside the collecting vehicle. And set up and carry and draw the device, then be favorable to along with the discharge of waste residue, the increase of piling up the height on the collection car constantly adaptability improves the space that the waste residue flows, avoids the waste residue to restrict to remain in the position sleeve, makes the waste residue that falls all can fill into in the collection car.
