Description

Technical Field

[0001] This utility model relates to the field of dairy product storage technology, and in particular to a stirring device for preventing sedimentation in dairy product storage tanks. Background Technology

[0002] Dairy products (such as fresh milk, yogurt base, and reconstituted milk powder) contain a large amount of heterogeneous components such as casein, milk fat, and lactose. During storage, they are prone to stratification or sedimentation due to density differences. Specifically, high-density casein particles tend to settle to the bottom of the container, forming hard clumps that are difficult to disperse again; low-density milk fat tends to float to the surface, forming an oily layer that disrupts the product's homogeneity. After prolonged standing (such as more than 4 hours), sedimentation and stratification will directly affect the quality of subsequent processing (such as sterilization and filling) and may even lead to the spoilage of raw materials.

[0003] However, the blades of commonly used storage tank agitators are mostly single-layered or fixed-angle designs, which can only cover the middle area inside the tank. The bottom, walls and top of the tank are prone to forming "agitation dead zones", and sediment will still accumulate in the dead zones. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a sedimentation prevention stirring device for dairy product storage tanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sedimentation prevention and stirring device for dairy product storage tanks, comprising a support frame, a round tank, and a square frame. A stirring mechanism is fixedly connected to the bottom of the round tank, and the stirring mechanism is fixedly connected to the middle of the square frame. The square frame is rotatably connected to the middle of the support frame. An angle positioning mechanism is provided at the central shaft end of the square frame. The stirring mechanism includes a reduction motor, a mounting frame, a drive sprocket, a chain, a driven sprocket, and a vertical stirrer. The vertical stirrer is formed by multiple sets of circumferentially arranged vertical frames and a set of discs. The vertical stirrer overlaps the inner wall of the round tank. The shaft of the driven sprocket passes through the bottom of the round tank and is fixedly connected to the middle of the disc of the vertical stirrer. The mounting frame is fixedly connected to the bottom of the round tank. The driven sprocket is driven by the chain and connected to the drive sprocket. The reduction motor is fixedly connected to the outside of the mounting frame, and its output shaft is fixedly connected to the middle of the drive sprocket.

[0006] Preferably, the mounting bracket is fixedly connected to the lower middle part of the square frame.

[0007] Preferably, the angle positioning mechanism includes a side frame, a ratchet, a pawl, a pull ring, a spring, and a connecting plate. The ratchet is fixedly installed at the end of the central shaft of the square frame, and the side frame is fixedly connected to the outside of the support frame and rotatably connected to the central shaft of the square frame.

[0008] Preferably, the pawl is engaged with the outside of the ratchet, and the pawl is rotatably connected to the middle of the side frame.

[0009] Preferably, the spring is fixedly connected to the outside of the pawl, and the other end of the spring abuts against the middle groove of the connecting plate.

[0010] Preferably, the connecting plate is fixedly connected to the outside of the side frame and located above the pawl, and the pull ring is fixedly connected to the outside of the pawl.

[0011] Preferably, multiple sets of double-layer shelves are fixedly connected in parallel on both sides of the inner side of the support frame. Each set of double-layer shelves is slidably connected to a drawer shelf in the middle. The drawer shelf is located below the round can, and the multiple sets of drawer shelves are distributed vertically and parallel to each other.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this invention, the geared motor in the stirring mechanism transmits power through a drive sprocket, chain, and driven sprocket, driving the vertical stirrer to rotate. Its upright frame covers the bottom, walls, and top of the cylindrical tank, enabling all-around stirring of the dairy products and preventing stratification and sedimentation from the source. On the other hand, the ratchet, pawl, and spring of the angle positioning mechanism work together to allow the square frame to rotate and lock the cylindrical tank stably, ensuring the dairy product surface is not parallel to the vertical stirrer disc, generating turbulence during stirring and significantly improving uniformity. This dual action ensures that the dairy products in the cylindrical tank remain uniform throughout storage, resulting in a significant anti-sedimentation effect.

[0013] 2. In this utility model, multiple sets of double-layered frames on both sides of the support frame provide stable sliding support for the drawer frame. The drawer frame is distributed vertically and located below the round can, which can accommodate filling containers of different heights. During filling, simply pull the drawer frame of the corresponding height to bring the container opening close to the opening of the round can, which not only avoids spillage of dairy products but also eliminates the trouble of frequently adjusting the container position, significantly improving filling efficiency. At the same time, the sliding design of the drawer frame also facilitates subsequent cleaning and storage, further optimizing the user experience of the device. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a sedimentation prevention stirring device for dairy product storage tanks, including a support frame 1, a round tank 5, and a square frame 7. A stirring mechanism 6 is fixedly connected to the bottom of the round tank 5. The stirring mechanism 6 is fixedly connected to the middle of the square frame 7, which is rotatably connected to the middle of the support frame 1. An angle positioning mechanism 4 is provided at the end of the central shaft of the square frame 7. The stirring mechanism 6 includes a reduction motor 61, a mounting frame 62, a drive sprocket 63, a chain 64, a driven sprocket 65, and a vertical stirrer 66. The vertical stirrer 66 consists of multiple... The vertical stirrer 66 is fixed to the inner wall of the cylindrical tank 5, and the driven sprocket 65 is fixed to the middle of the disc of the cylindrical tank 5 through the shaft of the driven sprocket 65. The mounting frame 62 is fixed to the bottom of the cylindrical tank 5. The driven sprocket 65 is connected to the driving sprocket 63 through the chain 64. The geared motor 61 is fixed to the outside of the mounting frame 62 and its output shaft is fixed to the middle of the driving sprocket 63. The mounting frame 62 is fixed to the lower middle of the square frame 7.

[0019] The angle positioning mechanism 4 includes a side frame 41, a ratchet 42, a pawl 43, a pull ring 44, a spring 45, and a connecting plate 46. The ratchet 42 is fixedly installed at the middle shaft end of the square frame 7. The side frame 41 is fixedly connected to the outside of the support frame 1 and rotatably connected to the middle shaft of the square frame 7. The pawl 43 is engaged with the outside of the ratchet 42 and rotatably connected to the middle of the side frame 41. The spring 45 is fixedly connected to the outside of the pawl 43. The other end of the spring 45 abuts against the middle groove of the connecting plate 46. The connecting plate 46 is fixedly connected to the outside of the side frame 41 and located above the pawl 43. The pull ring 44 is fixedly connected to the outside of the pawl 43.

[0020] The overall effect of this embodiment is as follows: By setting a stirring mechanism 6 at the bottom of the round tank 5, consisting of a geared motor 61, a mounting frame 62, a drive sprocket 63, a chain 64, a driven sprocket 65, and a vertical stirrer 66, and fixing the stirring mechanism 6 to the lower part of the square frame 7, stable transmission and efficient operation of stirring power are achieved. The geared motor 61 can provide power to reduce speed and increase torque. Through the transmission cooperation of the drive sprocket 63, the chain 64, and the driven sprocket 65, the vertical stirrer 66 can be precisely driven to rotate inside the round tank 5. The vertical stirrer 66 is composed of multiple sets of circumferentially arranged uprights and a set of discs. Its uprights can fully cover the bottom, walls, and top of the round tank 5. The circumferential movement of multiple sets of uprights can stir the dairy products in the round tank 5 in all directions, fundamentally avoiding the problem of stratification or sedimentation of dairy products due to standing. Meanwhile, by setting an angle positioning mechanism 4 at the central shaft end of the square frame 7, and utilizing the support and positioning of the ratchet 42 and pawl 43 by the side frame 41, as well as the elastic cooperation of the pawl 43, spring 45, and connecting plate 46, when the square frame 7 is turned to rotate the round tank 5 and the stirring mechanism 6, the ratchet 42 rotates, which pushes the pawl 43 outward and compresses the spring 45. The deformation elasticity of the spring 45 can also cause the pawl 43 to accurately engage with the subsequent ratchet groove of the ratchet 42, effectively limiting the rotation of the ratchet 42, thereby achieving stable locking after the square frame 7 rotates the round tank 5 to any angle. At this time, the liquid surface of the dairy product in the round tank 5 is no longer parallel to the disc of the vertical stirrer 66. When the vertical stirrer 66 continues to rotate, it can cause turbulence in the dairy product, greatly improving the uniformity of stirring, further strengthening the anti-sedimentation effect, and ensuring that the dairy product in the round tank 5 remains in a uniform state during storage. Afterward, pulling the pull ring 44 causes the pawl 43 to disengage from the ratchet 42, and the round tank 5 returns to its vertical state.

[0021] Example 2: Figure 1 - Figure 2 As shown, multiple sets of double-layer shelves 2 are fixedly connected in parallel on both sides of the inner side of the support frame 1. Each set of double-layer shelves 2 is slidably connected to a drawer shelf 3 in the middle. The drawer shelf 3 is located below the round can 5. The multiple sets of drawer shelves 3 are distributed vertically and parallel to each other.

[0022] The overall effect of this embodiment is as follows: By fixing multiple sets of double-layer frames 2 parallel to each other on both sides inside the support frame 1, and slidingly connecting drawer frames 3 in the middle of each set of double-layer frames 2, and positioning the multiple sets of drawer frames 3 below the round can 5 and in a vertically distributed and parallel manner, efficient adaptation and convenient support for the filling operation are achieved. The double-layer frames 2 can provide stable sliding tracks and structural support for the drawer frames 3, ensuring that the drawer frames 3 can be pushed and pulled smoothly. The multiple sets of drawer frames 3 distributed vertically can adapt to filling containers of different heights. When dairy products need to be filled, the operator can directly pull the drawer frame 3 of the corresponding height according to the height of the container and place the container stably on the drawer frame 3. This can accurately ensure the proximity of the container opening to the opening of the round can 5, which not only avoids the problem of dairy products spilling during the filling process due to improper container height, but also saves the trouble of frequently adjusting the container placement position, significantly improving the convenience and efficiency of the filling operation. At the same time, the sliding design of the drawer frames 3 also facilitates subsequent cleaning and storage, further optimizing the user experience of the device.

[0023] The operating method and working principle of this device are as follows: When storing dairy products, the cylindrical tank 5 is vertical. The lid is opened, and the dairy products are placed inside. The geared motor 61 is periodically started, and the reduced speed and increased torque drive the drive sprocket 63 to rotate. Under the transmission of the chain 64, the driven sprocket 65 rotates, thereby driving the vertical stirrer 66 to rotate inside the cylindrical tank 5. The vertical stirrer 66's frame covers the bottom, walls, and top of the cylindrical tank 5. Multiple sets of frames move in a circular motion to stir the dairy products in the cylindrical tank 5, preventing stratification or sedimentation. The square frame 7 is then turned, causing the central shaft of the square frame 7 to rotate on the support frame 1, driving the ratchet 42 at its end to rotate. The ratchet 42 pushes the pawl 43 outwards. During the flipping process, the connecting plate 46 compresses the spring 45. The elastic force generated by the deformation of the spring 45 reacts to the pawl 43, causing it to lock in the ratchet groove of the ratchet 42, thereby restricting the rotation of the ratchet 42. In this way, the square frame 7 drives the round tank 5 and the stirring mechanism 6 to flip and lock after a certain angle. At this time, the liquid surface of the dairy products inside the round tank 5 is no longer parallel to the disc of the vertical stirrer 66. As the vertical stirrer 66 continues to rotate and stir, the dairy products in the round tank 5 will generate turbulence, making the stirring more uniform and effectively preventing the dairy products from settling. When filling is required, the drawer frame 3 of different heights is pulled according to the height of the container, and the container is placed on the drawer frame 3 to ensure that the container opening is close to the opening of the round tank 5 for easy filling.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
