Description

Technical Field

[0001] This utility model relates to the field of dairy product storage technology, specifically to a dairy product storage device with high safety. Background Technology

[0002] Dairy products refer to various foods made primarily from cow's or sheep's milk and their processed products, with or without the addition of appropriate amounts of vitamins, minerals, and other auxiliary materials, processed according to the conditions required by laws, regulations, and standards. They are also called cream products. Dairy products include liquid milk, milk powder, and other dairy products. Due to the numerous processing steps involved in dairy product manufacturing, storage facilities are often required for prolonged storage during processing.

[0003] For example, a storage device for dairy product processing, as described in application number CN202420803294.0, includes a base plate. A sterilization mechanism for sterilizing dairy products is provided on one side of the top surface of the base plate. The bottom end of the sterilization mechanism is connected via a pumping assembly to a cooling mechanism located on the top surface of the base plate for cooling the dairy products after sterilization. This invention utilizes the combined operation of the sterilization and cooling mechanisms. The sterilization mechanism can uniformly heat and sterilize the dairy products, while the cooling mechanism can rapidly cool the sterilized dairy products, preventing nutrient loss. Furthermore, by using a filter assembly and a splicing assembly, the filter assembly can filter out sterilized microorganisms and bacteria from the dairy products, thereby improving the quality of the dairy products. The splicing assembly allows for quick disassembly and installation of the filter assembly, facilitating the cleaning of sediment after filtration, thus improving filtration efficiency.

[0004] In the aforementioned patent, the filtration and stirring functions are independent of each other, each equipped with its own independent drive motor. This design not only increases the number of core drive components such as motors, raising the production and manufacturing costs of the equipment, but also increases energy consumption due to the simultaneous operation of multiple motors. This results in high energy costs during long-term use, reducing the economic practicality of the device. Furthermore, the control logic of multiple motors is more complex, increasing the difficulty of equipment maintenance and the risk of failure. Moreover, relying solely on a single stirring shaft for stirring operations makes it difficult to achieve comprehensive coverage of the dairy products in the container, resulting in insufficient and uneven stirring. This also makes it easy for dairy products to adhere to the inner wall of the mixing container. If the residual dairy products are not cleaned in time, bacteria will grow on the container wall, easily causing cross-contamination during subsequent use, which will seriously affect the quality, safety, and stability of the dairy products.

[0005] Therefore, we propose a highly safe dairy product storage device to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a safe dairy product storage device to solve the problems mentioned in the background art, such as high operating costs, reduced economic practicality, poor stirring effect, and easy residue of dairy products adhering to the barrel wall, causing cross-contamination.

[0007] This utility model provides the following technical solution: a high-safety dairy product storage device, including a storage tank, a feed pipe connected to the top of the storage tank, a conveying pipe connected to one end of the storage pipe, a conveying pump installed on the conveying pipe, a stirring tank connected to one end of the conveying pipe, a stirring assembly provided inside the stirring tank, a filter barrel installed at the bottom of the stirring tank, an installation assembly installed between the stirring tank and the filter barrel, a filter assembly provided inside the filter barrel, a discharge pipe connected to one end of the filter barrel, and a valve provided on the discharge pipe.

[0008] Preferably, the stirring assembly includes a motor fixed to the top surface of the storage tank, a rotating rod fixed to the output end of the motor, a stirring shaft fixedly sleeved on the outer ring of the rotating rod, a fixing plate fixed inside the storage tank, a circular groove formed on the fixing plate, a gear fixedly sleeved on the outer ring of the rotating rod, a support ring fixed between the fixing plate and the storage tank, a gear ring rotating on the support ring, and the gear meshing with the gear ring.

[0009] Preferably, the outer ring of the gear ring is fixed with multiple connecting plates, the bottom of the connecting plates is fixed with a connecting rod, the connecting rod is slidably connected to the circular groove, and the bottom of the connecting rod is fixed with a stirring shaft.

[0010] Preferably, the mounting assembly includes a flange one that is fixedly fitted onto the outer ring of the mixing tank, a flange two that is fixed onto the outer ring of the filter barrel, and bolts that are fixedly connected between the flange one and the flange two.

[0011] Preferably, the filtration assembly includes two discharge pipes connected to the bottom of the mixing tank, and a control valve is provided in each discharge pipe.

[0012] Preferably, a rotating shaft is installed inside the filter barrel, and a sieve cylinder is fixedly sleeved on the outer ring of the rotating shaft. A cavity is opened at the top of the rotating shaft. An electromagnet is fixed on the bottom surface of the rotating rod, a telescopic rod is fixed on the bottom surface of the electromagnet, a permanent magnet is fixed on the bottom surface of the telescopic rod, and a brake pad is fixed on the bottom surface of the permanent magnet. The brake pad is in contact with the inner wall of the cavity. A spring is sleeved on the outer ring of the telescopic rod. One end of the spring is fixedly connected to the electromagnet, and the other end of the spring is fixedly connected to the permanent magnet.

[0013] This utility model has the following beneficial effects: 1. This storage device effectively solves the problem of sedimentation and stratification in dairy products after long-term storage, ensuring the quality stability of dairy products after removal. The device utilizes a coordinated stirring design with two stirring shafts to achieve comprehensive stirring of the inner wall and edge areas of the mixing tank. This dual stirring method not only breaks up sedimentation and stratification but also scrapes the tank walls, effectively preventing dairy product residue from adhering. Especially during filtration, the stirring components can operate at a low speed to scrape off any residual dairy product from the tank and walls and feed it into the filtration structure, reducing the possibility of bacterial growth from the source and preventing cross-contamination during subsequent use, ensuring the safety and consistency of dairy product quality.

[0014] 2. This storage device reduces equipment costs and energy consumption by using a shared drive motor for both stirring and filtration functions. Unlike existing devices that use separate motors for stirring and filtration, this device employs only one motor. An electromagnet controls the linkage between the rotating rod and shaft, allowing for flexible switching of power between the two functions. During the stirring phase, the rotating rod and shaft are separated, and the motor drives the stirring component independently. During the filtration phase, electromagnetic force causes the brake pads to engage with the shaft, and the motor drives the filtration component. This design reduces the number of core drive components, directly lowering manufacturing costs. Furthermore, the single-motor drive mode avoids the high energy consumption associated with multiple motors operating simultaneously, significantly reducing energy costs over the long term and enhancing the device's economic viability.

[0015] 3. This storage device has filtration capabilities, further enhancing the purity of dairy products. After stirring, the rotor drives the screen cylinder to rotate at high speed, using centrifugal force to quickly trap impurities and clumps in the dairy products. Pure dairy products that meet quality requirements then smoothly enter the filter tank. The entire filtration process is seamlessly integrated with the stirring function, requiring no additional power switching. While ensuring filtration effectiveness, it improves the overall efficiency of dairy product processing, providing high-quality raw materials for subsequent processing or use.

[0016] 4. The storage device effectively solves the problem of inconvenient cleaning and replacement of internal components of the mixing tank and filter barrel through the design of detachable installation components, and improves the ease of maintenance of the device. The device uses the installation structure composed of flange one, flange two and bolts, which allows the operator to quickly separate the mixing tank and filter barrel by simply loosening the bolts with tools, and directly contact the internal components for thorough cleaning or replacement of parts. The operation is simple and efficient. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: This example aims to address the problems in existing dairy product storage devices, such as the tendency for dairy products to settle and separate during long-term storage, high costs and energy consumption due to independent operation of stirring and filtration functions, incomplete stirring leading to residue, and poor filtration efficiency. Please refer to [link to relevant documentation]. Figure 1 - Figure 7A high-safety dairy product storage device includes a storage tank 1, a feed pipe 2 connected to the top of the storage tank 1, a conveying pipe 3 connected to the end of the storage pipe, a conveying pump 4 installed on the conveying pipe 3, a stirring tank 5 connected to the end of the conveying pipe 3, a stirring assembly 6 provided inside the stirring tank 5, a filter barrel 7 installed at the bottom of the stirring tank 5, a filter assembly 9 provided inside the filter barrel 7, a discharge pipe 10 connected to the end of the filter barrel 7, and a valve 11 provided on the discharge pipe 10.

[0027] The stirring assembly 6 includes a motor 61 fixed to the top surface of the storage tank 1. A rotating rod 62 is fixed to the output end of the motor 61. A stirring shaft 621 is fixedly sleeved on the outer ring of the rotating rod 62. A fixing plate 63 is fixed inside the storage tank 1. A circular groove 631 is opened on the fixing plate 63. A gear 64 is fixedly sleeved on the outer ring of the rotating rod 62. A support ring 65 is fixed between the fixing plate 63 and the storage tank 1. A gear ring 66 rotates on the support ring 65. The gear 64 and the gear ring 66 mesh with each other. Multiple connecting plates 67 are fixed to the outer ring of the gear ring 66. A connecting rod 68 is fixed to the bottom of the connecting plate 67. The connecting rod 68 is slidably connected to the circular groove 631. A stirring shaft 69 is fixed to the bottom of the connecting rod 68.

[0028] The filter assembly 9 includes two discharge pipes 91 connected to the bottom of the mixing tank 5. A control valve 92 is installed in the discharge pipe 91. A rotating shaft 93 rotates inside the filter barrel 7. A screen cylinder 94 is fixedly sleeved on the outer ring of the rotating shaft 93. A cavity 95 is opened at the top of the rotating shaft 93. An electromagnet 96 is fixed on the bottom surface of the rotating rod 62. A telescopic rod 98 is fixed on the bottom surface of the electromagnet 96. A permanent magnet 99 is fixed on the bottom surface of the telescopic rod 98. A brake pad 910 is fixed on the bottom surface of the permanent magnet 99. The brake pad 910 is in contact with the inner wall of the cavity 95. A spring 97 is sleeved on the outer ring of the telescopic rod 98. One end of the spring 97 is fixedly connected to the electromagnet 96, and the other end of the spring 97 is fixedly connected to the permanent magnet 99.

[0029] In this embodiment: When storing dairy products, the workers first pour the dairy products to be stored into the storage tank 1 through the feed pipe 2, completing the basic storage process. Because dairy products contain rich protein and other nutrients, some of their internal components are prone to sedimentation due to gravity during long-term static storage. If such layered dairy products are directly taken out for use, the concentration difference caused by the sedimentation will seriously affect the product quality and taste. Therefore, it is necessary to treat this through the stirring and filtering structure of the device.

[0030] When staff need to retrieve dairy products, they first turn on the delivery pump 4 on the delivery pipe 3. Driven by the delivery pump 4, the dairy products in the storage tank 1 flow smoothly into the mixing tank 5 along the delivery pipe 3. In the initial state, the electromagnet 96 remains unenergized. At this time, the spring 97 and the telescopic rod 98 are both in a naturally contracted state. The permanent magnet 99 and the brake pad 910 at the bottom of the telescopic rod 98 move away from the inner wall of the cavity 95 at the top of the rotating shaft 93. There is no braking constraint between the rotating shaft 93 and the rotating rod 62. The rotating rod 62 can rotate freely within the cavity 95 of the rotating shaft 93 without causing the rotating shaft 93 to move synchronously, thus preparing for the subsequent mixing process.

[0031] Then, the motor 61, fixed to the top of the storage tank 1, is started, and the output of the motor 61 drives the rotating rod 62 to rotate stably. The stirring shaft 621, fixed to the outer ring of the rotating rod 62, rotates synchronously with the rotating rod 62, and begins the initial stirring of the dairy products in the stirring tank 5. At the same time, the gear 64, fixed to the outer ring of the rotating rod 62, also rotates. Since the gear 64 meshes with the gear ring 66 rotatably connected to the support ring 65, the rotation of the gear 64 drives the gear ring 66 to make a circular motion along the support ring 65. The multiple connecting plates 67, fixed to the outer ring of the gear ring 66, move synchronously with the gear ring 66. The connecting rod 68 at the bottom of the connecting plate 67 slides smoothly in the circular groove 631 of the fixed plate 63, thereby driving the stirring shaft 69 at the bottom of the connecting rod 68 to make a circular motion. The rotational stirring of the stirring shaft 621 and the circular stirring of the stirring shaft 69 work together to form a comprehensive stirring effect without dead angles, thoroughly stirring the sedimented and layered dairy products in the stirring tank 5, restoring their uniform texture and stable quality.

[0032] After the stirring process is completed, motor 61 is turned off first, and then electromagnet 96 is energized. The energized electromagnet 96 generates strong magnetism, creating a repulsive force with the permanent magnet 99 below. This repulsive force overcomes the elastic force of spring 97, pulling the permanent magnet 99 downwards, and the telescopic rod 98 extends synchronously. As the permanent magnet 99 moves downwards, its bottom brake pad 910 gradually approaches and tightly adheres to the inner wall of the cavity 95 of the rotating shaft 93. Friction force achieves relative braking between the rotating rod 62 and the rotating shaft 93. At this point, the rotating rod 62 and the rotating shaft 93 form a stable linkage structure, and the rotation of the rotating rod 62 directly drives the rotating shaft 93 to move synchronously.

[0033] Restart motor 61. Motor 61 drives rotor 62 to rotate and drives rotor 93 to rotate synchronously. At the same time, control valve 92 on discharge pipe 91 is opened. During this process, rotor 62 continuously drives stirring shaft 621, gear 64 and gear ring 66 to rotate, so that stirring shaft 621 rotates at a low speed and stirring shaft 69 moves in a circle along the tank wall. Through the coordinated action of stirring components 6, the residual dairy products on the inner wall and inside the mixing tank 5 are effectively scraped off. Since the previous stirring has made the dairy products uniform in texture, the scraped dairy products can smoothly collect and flow out through discharge pipe 91. In addition, the discharge port of discharge pipe 91 is precisely aligned with the position of sieve cylinder 94, so the dairy products will flow into the inside of sieve cylinder 94. Since rotor 93 and sieve cylinder 94 are fixedly connected, when rotor 62 drives rotor 93 to rotate, sieve cylinder 94 on the outer ring of rotor 93 also rotates at high speed, using centrifugal force to efficiently filter the flowing dairy products. Impurities and lumps that may be present in the dairy products are trapped inside the sieve cylinder 94, while pure dairy products that meet quality requirements pass through the sieve holes of the sieve cylinder 94 and fall into the filter barrel 7. After the filtration process is completed, the operator opens the valve 11 on the discharge pipe 10, and the filtered qualified dairy products can be smoothly discharged through the discharge pipe 10 for subsequent processing or use.

[0034] Example 2: This example aims to address the problem of the fixed connection between the stirring tank 5 and the filter tank 7, which makes disassembly difficult and leads to difficulties in cleaning and replacing internal components. This example is an improvement on Example 1. For details, please refer to Example 1. Figure 1 - Figure 2 An installation assembly 8 is installed between the mixing tank 5 and the filter barrel 7. The installation assembly 8 includes a flange 81 that is fixedly fitted onto the outer ring of the mixing tank 5, and a flange 82 that is fixed onto the outer ring of the filter barrel 7. Bolts 83 are fixedly connected between flange 81 and flange 82.

[0035] In this embodiment: During long-term use, components such as the first stirring shaft 621 and the second stirring shaft 69 inside the stirring tank 5, as well as the sieve cylinder 94 inside the filter tank 7, are prone to accumulating dairy product residue. If not cleaned in time, bacteria will grow, affecting the safety of subsequently stored dairy products. Some components also need to be replaced promptly after wear. At this time, the operator can use tools to loosen the bolts 83 between flange 1 81 and flange 2 82. After all bolts 83 are removed, the stirring tank 5 corresponding to flange 1 81 and the filter tank 7 corresponding to flange 2 82 can be separated, thus achieving the separation of the two.

[0036] After disassembly, workers can directly access the mixing assembly 6 inside the mixing tank 5 and the filter assembly 9 inside the filter barrel 7 to clean residual dairy products on the mixing shaft 621 and mixing shaft 69. The sieve cylinder 94 can be removed from the filter barrel 7, and any impurities trapped inside can be cleaned. If the sieve cylinder 94 is damaged or the mixing assembly 6 malfunctions, it can be replaced directly. After cleaning or replacement, the flange 81 of the mixing tank 5 and the flange 82 of the filter barrel 7 are aligned, and the two are reconnected with bolts 83, ensuring a tight, leak-free connection, before the device can be put back into use. This detachable structure improves the ease of maintenance of the device and ensures hygiene and safety during the storage and processing of dairy products.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
