Description

Technical Field

[0001] The utility model relates to the technical field of rice hull steaming machines, in particular to a multi-layer turntable rice hull steaming machine. Background Technique

[0002] Rice hulls are important additives in the process of liquor brewing. For example, they need to be added at the saccharification and bacteria cultivation stage, fermentation stage, and distillation stage. Among them, during the saccharification and bacteria cultivation process of Xiaoqu Qingxiang cooked materials, usually a layer of rice hulls is spread under the saccharified materials and a layer of rice hulls is covered on the upper layer of the saccharified materials. Spreading rice hulls can effectively prevent the saccharified materials from sticking to the mesh plate, and covering rice hulls can play a good heat preservation role for the saccharified materials. However, raw rice hulls cannot be directly used during the brewing process and usually need to be processed by high-temperature steaming to become cooked rice hulls before being used as brewing auxiliary materials.

[0003] There are mainly two processes for the existing rice hull steaming: continuous production and discontinuous production. The former has a large output and high production efficiency, and the main equipment is steel belt type and chain plate type rice hull steaming machines; the latter has a small output and low production efficiency. Usually, a wine steamer is used and clear steam is added in the bottom pot, and some use a tank truck to steam with steam. Some use a steaming tower type rice hull steaming machine, which is shaped like a silo. Due to its structural limitations, it cannot carry out continuous production and generally has intermittent feeding and discharging.

[0004] In order to improve the rice hull processing capacity, currently, wineries increasingly use steel belt type and chain plate type rice hull steaming machines, and their main structures are similar. They are mainly divided into two parts: a steaming section and a cooling section. Among them, the steaming section is composed of a set of rotating chain plates or a steel belt driven by rollers, a steaming section frame, a feeding hopper, a tunnel-shaped box, a steaming chamber, a steam pipeline assembly, a drainage pipeline assembly, etc.; the cooling section is composed of a set of rotating chain plates or a steel belt driven by rollers, a cooling section frame, an air outlet top cover, a tunnel-shaped box, a cooling chamber, a discharging hopper, etc.; in order to fully steam or cool the rice hulls in the tunnel-shaped box, the chain plates or steel belts carrying the rice hulls must be perforated.

[0005] However, during the actual production process, rice hull debris, chaff, etc. on the steel belt or chain plate will fall into the steaming chamber and the cooling chamber through the mesh holes; when the materials falling in the steaming chamber accumulate too much or for a long time, they will become moldy and carbonized, making it inconvenient to clean. One of the purposes of steaming rice hulls is to remove the strange and miscellaneous odors in the chaff. Therefore, if the materials falling in the steaming chamber become moldy, the musty smell will be transmitted to the chaff in the tunnel-shaped box on the mesh belt through the steam, which will reduce the quality of the clear-steamed rice hulls; and when the materials falling in the cooling chamber accumulate too much, it will affect the air supply surface and cooling effect of the centrifugal fan in the cooling chamber, resulting in an extended dehumidification and cooling time for the finished rice hulls and affecting the output; therefore, the fallen rice hulls need to be cleaned in time.

[0006] Currently, the materials falling in the steaming chamber and the cooling chamber are both manually cleaned by workers on site. At 25m 3For example, for a tunnel-type rice bran steamer with a production capacity of 10000 tons / h, under normal production conditions, the falling materials in the cooking chamber of each rice bran steamer need to be cleaned 1 to 2 times a month, and the falling materials in the cooling chamber need to be cleaned 1 to 2 times a week. If there are multiple rice bran steamers in production, the number of cleaning times will increase exponentially. Currently, the cleaning is done manually by operators, who need to use tools such as cleaning rakes, shovels, and brooms to clean out the rice husk falling materials. When cleaning, they need to bend down and dust flies. The entire cleaning process is labor-intensive, the working environment is relatively harsh, the labor cost is extremely high, and the production line needs to be shut down, which reduces production efficiency.

[0069] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and the specific embodiments.

[0070] Embodiment:

[0071] As Figures 1 to 8 shown, the embodiment of the present application discloses a multi-layer rotary rice husk steaming machine, which can carry out continuous production, has the advantages of large output and high production efficiency, and does not stick to materials or leak materials, so it does not need to be cleaned regularly. Its specific structure includes: a top cover 1, a barrel body 2, a conical hopper 3, a material pipe 4, a rotary mechanism 5, a column 6, and a multi-layer steaming layer 7.

[0072] A steam discharge pipe 13 is provided at the top of the top cover 1. The steam discharge pipe 13 is a straight pipe arranged vertically and is used to discharge the internal steam.

[0073] The barrel body 2 is cylindrical and is arranged at the bottom of the top cover 1; the barrel body 2 is vertically through, and the shape and size of the top opening match those of the top cover 1 and are connected by welding, which improves the structural compactness and regularity of the device.

[0074] The conical hopper 3 is arranged at the bottom of the barrel body 2; the shape and size of the top opening of the conical hopper 3 match those of the bottom opening of the barrel body 2 and are connected by welding, which improves the structural compactness and regularity of the device; its inner cavity gradually shrinks from top to bottom and has an opening at the bottommost part, which is used to smoothly converge the steamed rice husks and avoid material accumulation and jamming.

[0075] The material pipe 4 has a vertical section 41 and an inclined section 42, and the bottom end of the vertical section 41 passes through the top cover 1 and is connected to the inclined section 42; the vertical section 41 is vertically arranged and can rotate around the axis, which is used to drive the inclined section 42 to rotate, so as to feed materials into each material bin 7a.

[0076] The rotary mechanism 5 is installed on the top of the top cover 1 and is in transmission connection with the vertical section 41, which is used to drive the vertical section 41 to rotate.

[0077] The column 6 is arranged vertically at the inner center of the barrel 2; the column 6 is cylindrical to ensure that the turntable 72 can rotate smoothly, and the upper and lower ends are conical to play a guiding role, avoiding the accumulation of materials at the ends and improving the use effect.

[0078] The multi-layer steaming material layer 7 is arranged at intervals up and down and is used to steam the rice husk multiple times. In this embodiment, it is set to two layers, but it is not limited to this. In actual production, the corresponding number of layers can be set according to the output size and the steaming time, so it is not specifically limited.

[0079] Specifically, each steaming material layer 7 includes: a plurality of steam pipes 71 , a rotating disk 72 , a rotating drive mechanism 73 and a plurality of vertical partitions 74 .

[0080] Among them, multiple steam pipes 71 are provided with multiple exhaust holes, which are horizontally arranged in the barrel 2 and are arranged around the pillars 6, and the inlet ends pass through the outside of the barrel 2.

[0081] Exemplarily, four steam pipes 71 are provided and arranged in a cross shape, but this is not limited thereto, and the number may be less or more and is arranged accordingly according to usage requirements, so no specific limitation is made.

[0082] Preferably, one end of the steam pipe 71 is fixedly connected to the column 6 to play a supporting role and improve the stability of the structure; the exhaust hole is arranged on the bottom surface of the steam pipe 71 so that the opening faces downward, which helps to prevent blockage and ensure stable operation of the equipment.

[0083] The turntable 72 is located above the steam pipe 71 and is coaxially movably sleeved on the column 6. It can rotate around the axis of the column 6, and a plurality of steam holes 721 and a fan-shaped discharge port 722 are opened on the top surface.

[0084] It should be noted that the steam holes 721 are evenly distributed on the entire top surface of the turntable 72 ( Figure 7 and Figure 8 The rotary disk 72 is only partially shown and not fully shown in the figure), which is used to allow steam to pass through the rotary disk 72 to cook the rice husks in each silo 7a.

[0085] The rotation driving mechanism 73 is disposed outside the barrel 2 and is transmission-connected to the turntable 72 to drive the turntable 72 to rotate.

[0086] The bottom surfaces of the plurality of vertical partitions 74 are fitted with the turntable 72 and are evenly arranged around the column 6 , with one end connected to the barrel 2 and the other end connected to the column 6 , so as to separate and form a plurality of silos 7 a matching the discharge port 722 .

[0087] Exemplarily, nine vertical partition plates 74 are provided, so that the internal space of the cylinder body 2 is evenly divided into nine equal parts in the circumferential direction, thereby forming nine fan-shaped bins 7a of the same size; however, it is not limited thereto, and corresponding adjustments can be made according to the required number of bins 7a, without specific limitations.

[0088] The main operation process of the above technical solution is as follows:

[0089] The upstream feeding device conveys rice husks to the feed pipe 4, and the feed pipe 4 then sequentially feeds the rice husks into each bin 7a of the topmost steaming layer 7. Specifically: when feeding the first bin 7a of the topmost layer, the rotary mechanism 5 drives the vertical section 41 of the feed pipe 4 to rotate, so that the inclined section 42 rotates to be directly above the first bin 7a, and thus the material sequentially passes through the vertical section 41 and the inclined section 42 and falls into the first bin 7a. Since the discharge port 722 is directly below the last bin 7a at this time, the rice husks can gradually accumulate in the first bin 7a. When the rice husk layer in the first bin 7a reaches the height requirement, the rotary mechanism 5 drives the vertical section 41 of the feed pipe 4 to rotate again, so that the inclined section 42 rotates to be directly above the second bin 7a, and thus starts to feed the second bin 7a, and so on, completing the cloth feeding work of the rice husks in each bin 7a of the topmost steaming layer 7 one by one.

[0090] Preferably, a high-level sensor is installed on the upper part of each bin 7a in the topmost steaming layer 7, which is used to feedback signals to judge whether the rice husk layer in the bin 7a reaches the set height, so as to judge whether to start the rotary mechanism 5 accordingly, so that the inclined section 42 rotates to be directly above the next bin 7a, thereby realizing automatic operation and improving production efficiency.

[0091] In the topmost steaming layer 7, when the first bin 7a is fed, the steam pipe 71 of this layer starts to input steam, and the rice husk cooking process starts immediately; when the penultimate bin 7a starts to be fed, the rotary drive mechanism 73 drives the turntable 72 to rotate, so that the discharge port 722 rotates to be directly below the first bin 7a, so that the first bin 7a starts to discharge, and the preliminarily steamed rice husks therein fall into the first bin 7a of the second-layer steaming layer 7. At the same time, the steam pipe 71 of the second layer starts to input steam, so that the second layer starts to perform re-steaming; and so on, so that the rice husks are cooked layer by layer in each layer of the steaming layer 7 from top to bottom for multiple times.

[0092] Preferably, a solenoid valve is installed at the inlet end of the steam pipe 71, so as to control whether steam is introduced into the steam pipe 71, which realizes automatic operation and improves production efficiency.

[0093] It should be noted that the rice husks in the silo 7a follow the first-in, first-out principle. That is, in the topmost steaming layer 7, when the second-to-last silo 7a finishes feeding, the first silo 7a finishes discharging; immediately afterwards, the last silo 7a starts feeding, and the second silo 7a starts discharging. After it is completed, the first silo 7a starts feeding again, and the third silo 7a starts discharging. Such a cycle enables a continuous production process of feeding and discharging simultaneously, and the other layers of the steaming layer 7 follow the same pattern.

[0094] First of all, by setting multiple steaming layers 7 in the present utility model, the rice husks can be steamed multiple times, and the rice husks are conveyed into the evenly distributed silos 7a through the rotating material pipe 4, without the need to flatten the rice husks, thus avoiding the problem of easy arching caused by compaction during the flattening process.

[0095] Secondly, by setting the vertical partition plates 74 to divide the internal space into multiple silos 7a, and then opening discharge ports 722 on the turntable 72, when the turntable 72 rotates, the rice husks in each silo 7a can be discharged in sequence. Finally, combined with the rotating feeding of the material pipe 4, a continuous production of feeding and discharging simultaneously is achieved, thereby expanding the output and improving the production efficiency.

[0096] Thirdly, the present utility model has a fully enclosed structure, enabling the steamed rice husks to be directly output to downstream equipment, thus avoiding the problems of sticking and leaking materials in chain plate and steel belt type rice bran steamers, keeping the production environment clean and tidy, and eliminating the need for regular manual cleaning and shutting down the production line, reducing labor costs and improving production efficiency.

[0097] Finally, the present utility model can realize unmanned online production of the rice bran steamer in cooperation with other sensors and video monitoring equipment. The operator can control the operation of the rice bran steamer in the central control room. For example, the material level information on the silo 7a, the steam pressure information on the steam pipe 71, the valve switch signal, the opening and closing signal of the slewing mechanism 5, the opening and closing signal of the turntable 72, etc. are all displayed on the control screen. This greatly improves the working environment of front-line production personnel and eliminates the need to endure noise pollution, dust pollution, etc. during the traditional rice bran steaming production process for a long time.

[0098] In some embodiments, as Figures 1 to 2 shown, it further includes: a water collecting trough 8 and a drain pipe 9; wherein, the water collecting trough 8 has an annular structure and is arranged at the inner peripheral top of the cylinder body 2; the drain pipe 9 is arranged outside the cylinder body 2 and is connected to the water collecting trough 8.

[0099] Specifically, the water collecting trough 8 is preferably integrally formed with the top cover 1 for easy production and manufacturing; during use, the condensed water on the inner wall of the top cover 1 flows along the inner surface into the water collecting trough 8, and then is drained away through the drain pipe 9, preventing the steam condensate from dripping into the rice husks and improving the steaming effect.

[0100] Based on the above embodiments, as Figure 1 and Figure 2 shown, the top cover 1 has a conical structure, and the vertical section 41 is installed at the center of the top cover 1.

[0101] By setting the top cover 1 to have a conical structure, the condensed water on the inner wall of the top cover 1 can flow more smoothly along the inner surface into the water collecting tank 8; by setting the vertical section 41 at the center, the feeding pipe 4 can distribute the material more evenly, improving the cooking effect.

[0102] In some embodiments, as Figures 1 to 2 shown, it further includes: multiple support legs 10 and a discharging device 11; among them, the multiple support legs 10 are installed on the outer periphery of the conical hopper 3; the discharging device 11 is installed at the bottom outlet of the conical hopper 3.

[0103] Exemplarily, a frame is sleeved on the outer bottom end of the cylinder body 2, and the support legs 10 are installed at the bottom of the frame, and the number is set to four, but it can also be three or more, without specific limitation; it plays a role in stable support to ensure the stable operation of the equipment.

[0104] Exemplarily, the discharging device 11 is installed at the bottom outlet of the conical hopper 3; it is used to convey the rice husks falling into the conical hopper 3 to downstream equipment for cooling and then to the finished rice husk bin for storage. Preferably, it is a multi - tandem auger rice husk discharging machine, and this rice husk discharging machine is connected to the conical hopper 3 through a flange, which is convenient for disassembly and repair and has a tight connection, and can effectively prevent phenomena such as rice husk leakage, steam leakage, and water leakage during the production process.

[0105] In some embodiments, as Figure 2 and Figure 6 shown, to improve the rotational stability of the turntable 72, each steaming layer 7 further includes: a support frustum 75 and a support bottom plate 76; among them, the support frustum 75 is coaxially and fixedly sleeved on the column 6; the support bottom plate 76 is arranged at the bottom of the turntable 72, movably sleeved on the column 6, and a positioning groove 761 adapted to the support frustum 75 is opened on the bottom surface.

[0106] Preferably, a diversion block is arranged at the top of the support bottom plate 76 and inside the discharge opening 722. One side of the diversion block is in contact with the column 6, and the other side has an inclined surface, which is used to prevent rice husks from accumulating on the top surface of the support bottom plate 76, improving the use effect.

[0107] Specifically, the support frustum 75 is embedded in the bottom of the support bottom plate 76 through the positioning groove 761, so that the support bottom plate 76 is supported and can rotate around the column 6, thereby enabling the turntable 72 arranged on its top to be supported accordingly. It plays a role in axially limiting the turntable 72 and ensures the smoothness of rotation.

[0108] In some embodiments, as Figure 2 、Figure 5 So and Figure 8 As shown, in order to improve the rotation stability of the turntable 72 , each steaming material layer 7 further includes: a plurality of supporting rollers 77 , which are evenly arranged around the pillars 6 , installed on the inner circumference of the barrel 2 , and fit with the bottom surface of the turntable 72 .

[0109] Specifically, the support roller 77 supports the turntable 72, plays an axial limiting role, reduces friction, ensures smooth rotation, and improves the bearing capacity of the turntable 72 for rice husks, avoids deformation, and improves stability in long-term use.

[0110] In some embodiments, the rotary drive mechanism 73 is further designed, and its structure includes: a ring gear 731 , a cover 732 , a gear transmission group 733 and a first motor 734 .

[0112] Preferably, a reducer is provided between the first motor 734 and the gear transmission group 733, so as to increase the torque by reducing the rotation speed, thereby ensuring that the turntable 72 can be driven to rotate stably.

[0113] Specifically, a slot is provided on the barrel 2 and inside the cover 732, and the output end of the gear transmission group 733 extends into the barrel 2 through the slot and meshes with the gear ring 731; the cover 732 plays a sealing and protective role, and prevents internal steam from leaking to the outside of the device through the slot, and prevents external debris from interfering with the operation of the gear transmission group 733 and entering the interior of the device through the slot to cause pollution.

[0114] Through the above-mentioned design of the rotating drive mechanism 73, the turntable 72 can be smoothly driven to rotate. It has the characteristics of compact structure, stable transmission and convenient disassembly and assembly. It will not interfere with the up and down transportation of materials, is easy to inspect and maintain, and has a good comprehensive use effect.

[0115] In some embodiments, Figure 8 As shown, in order to improve the bearing capacity of the turntable 72 , each steaming material layer 7 includes: a supporting grid 78 , which is a grid-like structure and is arranged on the bottom surface of the turntable 72 .

[0116] Through the above arrangement, the bearing capacity and structural stability of the turntable 72 are significantly improved, the structural strength is increased, and the service life is extended.

[0117] In some embodiments, Figure 2 and Figure 4As shown, the vertical section 41 is rotatably connected to the top cover 1. The slewing mechanism 5 includes: a toothed ring 51, a second motor 52, and a driving gear 53. Among them, the toothed ring 51 is sleeved on the vertical section 41; the second motor 52 is installed on the top of the top cover 1; the driving gear 53 is coaxially and fixedly sleeved on the driving shaft of the second motor 52 and meshes with the toothed ring 51.

[0118] When driving, the driving shaft of the second motor 52 drives the driving gear 53 to rotate, and the driving gear 53 drives the toothed ring 51 to rotate, thereby driving the vertical section 41 to rotate synchronously.

[0119] Through the above settings, the vertical section 41 can be driven to rotate stably and smoothly, with a solid structure, which is convenient for installation, layout, inspection, and maintenance.

[0120] In some embodiments, as Figure 1 and Figure 5 shown, it further includes: a heat insulation layer 12, which is fixedly sleeved on the outside of the barrel body 2.

[0121] By setting the heat insulation layer 12, the loss of internal heat can be reduced, thereby improving the steaming effect and reducing the production cost.
