Description

Technical Field

[0001] The utility model relates to the technical field of material mixing, in particular to a two-dimensional mixer with a bend adding function. Background Art

[0002] In the traditional production process of Luzhou-flavor baijiu, a certain proportion of grain and bran are added to the lees before they are steamed in the distillery. The grain is added to prepare them for fermentation in the cellar after steaming; the bran is added to loosen the lees, increasing the gaps between them to facilitate the passage of vapor during distillation, thereby increasing the yield. Therefore, the grain, bran, and lees are mixed evenly before steaming. Currently, mixing the lees, grain, and bran is primarily done manually. The high temperatures and harsh environment in the distillery compromise worker health, leading to difficulties recruiting workers. Furthermore, manual mixing is labor-intensive and inefficient, and uneven mixing can affect yield.

[0003] The inventor of this application is committed to the research of intelligent brewing equipment, and in 2022 applied for a two-dimensional mixer with automatic opening and closing lid function with publication number CN115814660A, including a frame, a guide rail horizontally arranged on the frame, a mobile frame slidingly arranged on the guide rail, a first power mechanism arranged on the frame, a stirring tank, an opening and closing lid mechanism arranged on the mobile frame, and a locking mechanism arranged on the tank lid; the locking mechanism is used to lock the tank lid and the tank body.

[0004] However, the above-mentioned two-dimensional mixer is composed of a mixing tank and a tank cover. Before mixing, the material needs to be loaded into the mixing tank through a lifting hopper, and after mixing, the material needs to be poured into the hopper for transportation. It can be seen that during the mixing process, the material needs to be poured in and out. This logistics method is cumbersome, time-consuming, labor-intensive, and inefficient. To this end, in response to the above technical problems, the applicant applied for a mixing device that is convenient for material transportation with application number 202420778907X in 2024, with reference to Figure 1 The invention comprises a frame, a tank body, a hopper, a lifting assembly, a rotary lock assembly, and a power assembly; the tank body is arranged on the frame, and the hopper is arranged directly below the tank body. The hopper can dock with the open end of the tank body to seal the tank body; the lifting assembly is arranged directly below the tank body. However, the above application uses two separate components to lift and lock the hopper, resulting in a relatively complex structure. Moreover, the above application cannot add koji during the stirring process of the lees, lacks a koji adding function, and has a relatively simple function. Utility Model Content

[0039] In the description of the present invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0040] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0041] The following is combined with Figures 2 to 6 The utility model is further described.

[0042] Example 1

[0043] In view of the technical problems existing in the background technology, the utility model provides a two-dimensional mixer with a function of adding koji.

[0044] In the specific technical solution, refer to Figure 2 and Figure 3The two-dimensional mixer with a bend function includes a frame 1, a tank body 2, a hopper 3, a power assembly 4, and a lifting and locking assembly 5. The tank body 2 is arranged on the frame 1 and is movably connected to the frame 1. It is used to mix materials. One end of the tank body 2 is open. The hopper 3 is arranged directly below the tank body 2 and is used to transfer materials and seal the tank body 2. The shape of the hopper 3 matches the tank body 2. The power assembly 4 is arranged on the frame 1 and is used to drive the tank body 2 to rotate in the vertical direction to mix the materials. The lifting and locking assembly 5 is arranged on the tank body 2 and is used to lift the hopper 3 and lock the hopper 3 and the tank body 2. After lifting, the hopper 3 docks with the open end of the tank body 2 to seal the tank body 2.

[0045] The above structure is the same as that of the two-dimensional mixer in the prior art. The principle is to use the hopper used for transferring materials as a tank cover to seal the tank body, so that the hopper is used as both a transfer container and a sealing cover, thereby avoiding the transfer process of the traditional two-dimensional mixer that requires the material in the tank body to be repeatedly transferred between the tank body and the hopper. Therefore, the process is reduced, which is more conducive to the optimization of the production line layout and improves the mixing efficiency; it also avoids the overflow of the hopper from the material during the transfer process to pollute the environment. In addition, this device is a sealed mixer and does not leak material during the mixing process.

[0046] However, the power assembly of the prior art two-dimensional mixer is to directly drive the main shaft to rotate through the reduction motor, which has a large torque and requires a large motor power. There may be instability during the rotation process. Therefore, the utility model makes the following improvements to the power assembly: Figure 4 The power assembly 4 includes a first reduction motor 401 mounted on the frame 1. A gear (not shown) is connected to the output end of the first reduction motor 401. A main shaft 402 is mounted on the tank 2. A slewing bearing 403 is mounted on the main shaft 402, matching the gear. The gear is connected to the main shaft 402 via the slewing bearing 403. A secondary shaft 404 is mounted on the other side of the tank 2 relative to the main shaft. The secondary shaft 404 is connected to the frame 1 via a bearing seat 405. It can be seen that the improved power assembly utilizes a reduction motor coupled with a slewing bearing for drive, enabling continuous and stable output.

[0047] Secondly, adding koji is an important part of the brewing process. In order to meet the requirement of adding koji medicine to the lees in the tank during the mixing process of the tank, the utility model also makes the following improvements: Figure 4In this embodiment, the secondary shaft 404 is designed to be a hollow structure, one end of the secondary shaft 404 is connected to the outside, and the other end of the secondary shaft 404 is connected to the inside of the tank body 2. When it is necessary to add koji during the mixing process, the koji can be added to the material in the tank body 2 through the secondary shaft 404. Specifically, the device for adding koji can be a screw conveyor, which is inserted into the tank body 2 through the hollow secondary shaft 404. The screw conveyor is started, and the bolt conveyor can add the koji into the tank body 2. In order to achieve the sealing between the screw conveyor and the secondary shaft 404 and avoid the koji from escaping when adding koji, refer to Figure 4 Therefore, a sealing ring 406 is provided inside the end of the secondary shaft 404 connected to the tank body 2, and the sealing ring 406 is interference-fitted with the screw conveyor inserted therein. It can be seen that the present invention can not only add auxiliary materials such as koji medicine to the material synchronously during the mixing process, but also all auxiliary materials such as koji medicine are added in a closed cavity, which can effectively avoid dust and solve the problems of large dust and poor working environment; in addition, since the material is mixed in a quantitative manner when entering the tank body, other auxiliary materials can be accurately added according to the weight of the material, avoiding the problem of difficult accurate proportioning of materials and auxiliary materials in the form of online mixing.

[0048] The existing two-dimensional mixer uses a lifting assembly to lift the hopper, and then cooperates with a rotary lock assembly to lock the hopper and the tank body. The structure is relatively complex. In order to simplify the structure and improve the performance, the lifting and locking assembly 5 of this embodiment is specifically designed as follows: Figure 5 The lifting and locking assembly 5 includes four second reduction motors 501 and a housing 502 symmetrically arranged on opposite sides of the tank body where the main shaft is located. The output end of the second reduction motor 501 is connected to a screw 503, which is arranged vertically in the housing 502. A connecting plate 504 is provided on the screw 503, and the connecting plate 504 is arranged in the housing 502. The screw 503 passes through the connecting plate 504 and is hinged to the housing 502. A linear bearing 505 is provided on the connecting plate 504, and a bearing sleeve 506 movably connected to the linear bearing 505 is provided in the housing 502. The linear bearing 505 passes through the housing 502, and the linear bearing 505 extends out of the bottom of the housing 502. A lifting plate 507 for lifting the hopper 3 is provided. The second reduction motor 501 can drive the lifting plate 507 to rise and fall through the screw 503 and the linear bearing 505 in turn. The second reduction motor 501 is a brake motor, and the screw 503 is a T-type screw.

[0049] Working principle: The second reducer 501 drives the lead screw 503 to rotate. During the rotation of the lead screw 503, the linear bearing 505 can be driven to slide relative to the bearing sleeve 506. Since the bearing sleeve 506 is arranged on the housing 502, the linear bearing 505 will move up and down relative to the housing 502. The lifting plate 507 is arranged at the bottom of the linear bearing 505, so the lifting plate 507 will move up and down synchronously with the linear bearing 505. The lifting plate 507 is stuck in the mouth of the hopper 3, and the hopper 3 will move up and down synchronously with the lifting plate, completing the docking of the hopper 3 and the tank body 2.

[0050] It can be seen that the lifting locking assembly of the utility model adopts a T-type screw structure, which can realize the self-locking function, and the second reduction motor adopts a brake motor. After lifting into place, the second reduction motor brake is locked to realize the double-layer locking protection of the screw self-locking and the motor brake to prevent the hopper from detaching.

[0051] In order to detect the position of the hopper so that the equipment can proceed to the next step in an orderly manner, refer to Figure 5 Therefore, in this embodiment, proximity switches 508 for detecting the position of the lifting plate 507 are arranged at a certain distance vertically in the shell 502. When the proximity switch fails, in order to avoid excessive lifting of the lifting and locking assembly 5 and damage to the equipment, in this embodiment, limit switches 509 for detecting the extreme position of the lifting plate 507 are also arranged at a certain distance vertically in the shell 502. The proximity switch uses an electronic signal detection method, while the limit switch 509 uses a mechanical detection method. The two cooperate to further ensure the safe operation of the equipment. A control box 202 is provided on the tank body 2. The control box 202 performs overall control of the proximity switch 508, the limit switch 509 and the second reduction motor 501 of the lifting and locking assembly 5. The power supply and communication of the control box 202 are transmitted through the slip ring installed on the main shaft.

[0052] In order to reduce the difficulty of processing, the tank body 2 and the hopper 3 are designed to be square in the utility model.

[0053] Example 2

[0054] In order to improve the mixing degree of the materials and the mixing degree between the materials and the auxiliary materials, based on the first embodiment, this embodiment makes the following further improvements: Figure 6 and Figure 4 In this embodiment, partitions 201 are arranged obliquely at the four corners of the closed end of the tank body 2. During the rotation of the tank body 2, the partitions 201 can gather the materials toward the middle of the tank body 2.

[0055] Working Principle: During the rotation of the tank 2, material tends to accumulate at the four corners of the square hopper 3. When the hopper 3 is rotated to the top of the tank 2, the falling material is dispersed and falls to the surrounding area. When the tank 2 is rotated to the top of the hopper 3, the inclined partitions 201 arranged at the four corners of the tank 2 cause the material inside to gather toward the center of the tank as it falls. Therefore, the material is continuously mixed during this reciprocating process of dispersion and gathering, which improves the mixing degree of the material and makes the material mixing more uniform.

[0056] In order to improve the degree of automation of equipment and ensure the continuity of production, refer to Figure 2 This embodiment is also designed with a chain conveyor 6, which is arranged beside the frame 1 and extends to just below the tank body 2. The chain conveyor 6 is used to transport the hopper 3. The end of the chain conveyor 6 is provided with a sensor (not shown in the figure) for detecting the position of the hopper 3 and a barrier (not shown in the figure).

[0057] Working principle:

[0058] S1: The chain conveyor 6 transports the hopper 3 filled with lees from the previous process to the bottom of the tank 2.

[0059] S2: The power assembly 4 rotates the open end of the tank 2 downward, that is, toward the hopper 3 below it;

[0060] S3: The lifting and locking assembly 5 works, driving the hopper 3 to gradually rise and eventually contact the tank body 2, completing the complete sealing connection between the hopper 3 and the tank body 2;

[0061] S4: The power assembly 4 works, driving the tank 2 and the hopper 3 to rotate vertically synchronously to achieve material mixing;

[0062] S5: During the material mixing process, the koji medicine is added into the tank body 2 through the secondary shaft 404 and mixed together;

[0063] S6: After the materials are evenly mixed, the material is discharged. The power assembly 4 drives the open end of the tank body 2 downward. At this time, the tank body 2 is located above the hopper 3, and the material in the tank body 2 falls into the hopper 3;

[0064] S7: The lifting and locking assembly 5 drives the hopper 3 to gradually descend and finally stop on the chain conveyor 6; the chain conveyor 6 then transports the hopper 3 to the next process.

[0065] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
