Description

Technical Field

[0001] This invention relates to the field of lactic acid bacteria beverage raw material conveying technology, specifically to a residue-free self-cleaning conveying device for dry powder raw materials of lactic acid bacteria beverages. Background Technology

[0002] Lactic acid bacteria beverages are dairy-containing beverages made from milk or dairy products, fermented with lactic acid bacteria, and then mixed with water, sugar, and other auxiliary materials. During the production of lactic acid bacteria beverages, a conveying device is required to transport the beverage to the filling equipment. The production of lactic acid bacteria beverages also requires the conveying of dry powder raw materials.

[0003] A search revealed a Chinese patent with application number "CN202210995584.5", which specifically describes a self-cleaning conveying device for fermented feed. The device includes: a conveying cylinder with a rotating shaft inside, and spiral blades on the rotating shaft; a first scraper, which can rotate relative to the rotating shaft along the spiral blades, and is used to clean soft impurities; and a second scraper, which can rotate relative to the rotating shaft along the spiral blades, and is used to clean hard impurities.

[0004] Existing screw conveyor systems have the following problems when conveying dry powder raw materials for lactic acid bacteria beverages: After conveying, powder residue easily remains on the inner wall of the conveying pipe and on the screw blades. If this residue is not cleaned in time, it is prone to absorbing moisture, clumping, and breeding bacteria, affecting the quality of the dry powder conveyed in the next batch. Although existing devices can add cleaning solution to the conveying pipe through the water inlet pipe for cleaning, cleaning solution easily remains inside the pipe after cleaning. If this residue is not cleaned in time, it is also prone to breeding bacteria, causing contamination of the raw powder raw materials conveyed in the next batch, affecting the overall quality of the lactic acid bacteria beverage.

[0005] Therefore, this invention proposes a residue-free self-cleaning conveying device for lactic acid bacteria beverage dry powder raw materials to solve the aforementioned problems. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides the following technical solutions:

[0032] Example 1

[0033] Please see Figure 1 - Figure 5 , Figure 10 A residue-free self-cleaning conveying device for lactic acid bacteria beverage dry powder raw materials includes a conveying pipe 1, a support frame 2 fixedly connected to the outer side of the conveying pipe 1, a powder inlet pipe 3 and a water inlet pipe 6 fixedly connected to the upper side of the conveying pipe 1, a powder discharge pipe 5 fixedly connected to the lower side of the conveying pipe 1, and a cleaning unit 7 provided on the inner side of the conveying pipe 1. The cleaning unit 7 includes a rotating pipe 71, which is rotatably connected to the inner side of the conveying pipe 1. A spiral blade 72 is fixedly connected to the outer side of the rotating pipe 71. A moving groove 726 is opened on the inner wall of the upper end of the rotating pipe 71. A moving block 727 is provided on the inner side of the moving groove 726. A telescopic pipe 728 is fixedly connected to the outer side of the moving block 727. An output pipe 725 is fixedly connected to the upper side of the telescopic pipe 728. A fixed cover 73 is fixedly connected, and a hot air blower 75 is fixedly connected to the outside of the fixed cover 73. Multiple air outlets 76 are opened on the outside of the rotating pipe 71. The moving block 727 is slidably connected to the moving groove 726. A gear component 77 is fixedly connected to the outside of the rotating pipe 71. A top frame 723 is fixedly connected to the upper side of the conveying pipe 1. A rotating shaft 78 is rotatably connected to the lower side of the top frame 723. A gear component 79 that meshes with the gear component 77 is fixedly connected to the outside of the rotating shaft 78. A motor 724 that drives the rotating shaft 78 to rotate is fixedly connected to the upper side of the top frame 723. The gear component 77 and the gear component 79 are slidably connected. The upper end of the rotating pipe 71 passes through the upper side of the conveying pipe 1. The rotating pipe 71 is slidably connected to the conveying pipe 1, so that the rotating pipe 71 can move up and down.

[0034] When conveying the raw materials for lactic acid bacteria beverages, the powder is poured into the conveying pipe 1 through the powder inlet pipe 3. The motor 724 is started, and the motor 724 drives the rotating shaft 78 to rotate. The rotating shaft 78 drives the gear component 2 79 to rotate, the gear component 2 79 drives the gear component 1 77 to rotate, the gear component 1 77 drives the rotating pipe 71 to rotate, and the rotating pipe 71 drives the spiral blade 72 to rotate, which facilitates the conveying of the powder by the spiral blade 72. The powder is discharged through the powder discharge pipe 5. After the conveying is completed, the cleaning agent is introduced into the interior of the conveying pipe 1 through the water inlet pipe 6 to facilitate the cleaning of the spiral blade 72 and the interior of the conveying pipe 1. After a period of time, the cleaning agent soaks the stubborn residue inside. The cover plate 4 is bolted to the conveying pipe 1. The bolts are loosened to remove the cover plate 4, allowing the cleaning agent to be discharged, which is convenient for cleaning the residual cleaning agent through the cleaning unit 7.

[0035] The lower end of the hot air blower 75 is fixedly connected to an air supply pipe 747, which is located inside the output pipe 725. Multiple heat dissipation holes 74 are opened on the outer side of the fixed cover 73. A cover plate 4 is provided on the lower side of the conveying pipe 1. The output pipe 725 is rotatably connected to the fixed cover 73. When the air outlet 76 is connected to the connecting hole 711, the hot air blower 75 is started. Under the action of the air supply pipe 747, the telescopic pipe 728 and the rotating pipe 71, hot air is discharged from the air outlet 76 into the interior of the conveying pipe 1, which facilitates the cleaning of residual powder in the conveying pipe 1.

[0036] A vertical rod 713 is fixedly connected to the inner side of the rotating tube 71. A top block 712 is provided on the outer side of the vertical rod 713. A sealing plate 710 is fixedly connected to the lower side of the top block 712. Multiple connecting holes 711 are opened on the outer side of the sealing plate 710. A fixing plate 714 is fixedly connected to the inner wall of the rotating tube 71. A sliding groove 715 is opened on the outer side of the fixing plate 714. A slider 716 is slidably connected to the inner side of the sliding groove 715. A rotating block 717 is fixedly connected to the upper side of the slider 716. An inclined plate 718 is rotatably connected to the outer side of the rotating block 717. A rotating block 719 is fixedly connected to the lower side of 712. An inclined plate 718 is rotatably connected to the rotating block 719. The top block 712 is slidably connected to the upright rod 713. Air outlets 76 and connecting holes 711 are arranged alternately. A sliding rod 721 is fixedly connected to the inner wall of the rotating pipe 71. A centrifugal plate 720 is fixedly connected to the right side of the rotating block 717. A spring 722 is fixedly connected between the centrifugal plate 720 and the inner wall of the rotating pipe 71. The sliding rod 721 is slidably connected to the centrifugal plate 720. After cleaning, the speed of the motor 724 is controlled to accelerate the electric... The high speed of motor 724 drives shaft 78 to rotate, which in turn drives gear 79 to rotate. Gear 79 drives gear 77 to rotate, which in turn drives tube 71 to rotate. Tube 71 drives internal fixed plate 714 to rotate, which in turn drives centrifugal plate 720 to rotate. Due to the high speed of motor 724, centrifugal force causes centrifugal plate 720 to move closer to the inner wall of tube 71. Centrifugal plate 720 drives slider 716 to move, which in turn drives inclined plate 718. When rotated, the inclined plate 718 drives the top block 712 to descend, the top block 712 drives the sealing plate 710 to descend, and the sealing plate 710 drives the connecting hole 711 to descend, so that the connecting hole 711 connects with the air outlet 76, which facilitates the discharge of hot air into the interior of the conveying pipe 1 and facilitates the cleaning of residual cleaning agent. When conveying (when the motor 724 is at full speed), under the action of the spring 722, the centrifugal plate 720 is reset, the sealing plate 710 rises, and the sealing plate 710 seals the air outlet 76 to prevent powder from entering the interior of the rotating pipe 71 during conveying.

[0037] Example 2

[0038] Based on Example 1, such as Figure 6 - Figure 9As shown, a stabilizing ring 736 is fixedly connected to the outer side of the output tube 725. A rectangular block 737 is fixedly connected to the outer side of the stabilizing ring 736. A rotating rod 738 is rotatably connected to the outer side of the rectangular block 737. A control block 739 is fixedly connected to the front end of the rotating rod 738. A linkage plate 740 is rotatably connected to the front side of the control block 739. A fixed disk 729 is fixedly connected to the outer side of the rotating tube 71. A rotating block 741 is fixedly connected to the upper side of the fixed disk 729. The linkage plate 740 and the rotating block 741 are rotatably connected. A bevel gear 742 is fixedly connected to the rear end of the rotating rod 738. A limit block 744 is fixedly connected to the rear side of the rectangular block 737. A control rod 745 is rotatably connected to the outer side of the limiting block 744. A second bevel gear 743, meshing with a first bevel gear 742, is fixedly connected to the left end of the control rod 745. A third gear 746 is fixedly connected to the right end of the control rod 745. A mounting ring 730 is fixedly connected to the right side of the top frame 723. A fixing rod 731 and an electric push rod 735 are fixedly connected to the upper side of the mounting ring 730. A top ring 733 is located below the third gear 746. Multiple branch blocks 732 are fixedly connected to the outer side of the top ring 733. Multiple toothed blocks 734 are fixedly connected to the upper side of the top ring 733. The electric push rod 735 is fixedly connected to the branch blocks 732. The fixed rod 731 is slidably connected to the branch block 732, and the gear component 746 is meshed with the toothed block 734. When cleaning residual cleaning agent, the control electric push rod 735 drives the top ring 733 to rise, the top ring 733 drives the toothed block 734 to rise, the toothed block 734 meshes with the gear component 746, the rotating tube 71 drives the output tube 725 to rotate, the output tube 725 drives the stabilizing ring 736 to rotate, the stabilizing ring 736 drives the rectangular block 737 to rotate, the rectangular block 737 drives the gear component 746 on the control rod 745 to revolve, and under the action of the toothed block 734, the gear component 746 rotates on its own axis. The control lever 745 rotates, which in turn rotates the second bevel gear 743. The second bevel gear 743 then rotates the first bevel gear 742, which in turn rotates the rotating rod 738. The rotating rod 738 then rotates the control block 739, which in turn rotates the linkage plate 740. The linkage plate 740 then moves the fixed plate 729 up and down reciprocally, which in turn moves the rotating pipe 71 up and down reciprocally. This facilitates the rotating pipe 71 moving the air outlet 76 up and down, further improving the cleaning effect. During the cleaning process, the rotating pipe 71 can also be controlled to move up and down reciprocally to stir the cleaning agent, further enhancing the cleaning effect.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] During operation, powder is first poured into the conveying pipe 1 through the powder inlet pipe 3. Then, the motor 724 is started, which drives the gear 79 on the rotating shaft 78 to rotate. Under the action of the gear 77, the spiral blade 72 on the rotating pipe 71 is controlled to rotate, facilitating the conveying of powder by the spiral blade 72. The powder is then discharged through the powder outlet pipe 5. After conveying, cleaning agent is introduced into the conveying pipe 1 through the water inlet pipe 6 to clean the interior. After cleaning, the cleaning agent is discharged. At this time, the motor 724 is controlled to increase its speed, thereby increasing the speed of the rotating pipe 71. The rotating pipe 71 drives the fixed plate 714 to rotate. Under the action of centrifugal force, the centrifugal plate 720 moves closer to the inner wall of the rotating pipe 71. The centrifugal plate 720 drives the slider 716 to move. Under the action of the inclined plate 718, the slider 716 is controlled to rotate. The top block 712 descends, causing the sealing plate 710 to descend as well, connecting the connecting hole 711 with the air outlet 76. At this time, the hot air blower 75 is activated, causing the air outlet 76 to spray hot air into the inside of the conveying pipe 1, facilitating the cleaning of residual cleaning agent inside. During the cleaning process, the electric push rod 735 is controlled to drive the toothed block 734 on the top ring 733 to rise. The toothed block 734 meshes with the gear component 746. When the rotating tube 71 rotates, the gear component 746 is controlled to revolve. Under the action of the toothed block 734, the gear component 746 rotates on its own axis. Under the action of the control rod 745, bevel gear 743, bevel gear 742, rotating rod 738, control block 739 and linkage plate 740, the rotating tube 71 on the fixed plate 729 is controlled to move up and down reciprocally, improving the cleaning effect.
