Description

Technical Field

[0001] This utility model relates to the technical field of dairy product processing, and in particular to an impurity filtration device for dairy product processing. Background Technology

[0002] Impurity filtration devices for dairy processing are specialized equipment used to remove solid impurities (such as hair, feed residue, microbial clumps, coagulated protein, etc.) from dairy products such as milk, yogurt, and cheese, in order to ensure product purity, taste, and food safety.

[0003] In related technologies, the main mechanisms of commonly used filtration devices employ methods such as screen / cartridge filtration, centrifugal filtration, membrane filtration, or vibrating screen / rotary screen filtration. Among these, stainless steel screens or cartridges are used, relying on gravity or pump pressure to force dairy products through the screen and intercept larger particulate impurities; centrifugal filtration utilizes the high-speed rotation of a centrifuge to throw out impurities in dairy products due to density differences; membrane filtration uses precision filter media such as ceramic membranes and polymer membranes, using pressure to filter out tiny particles; and vibrating screens / rotary screens vibrate or rotate under the drive of a motor.

[0004] In actual filtration processes, the aforementioned devices mostly employ single-stage static filtration, resulting in low filtration efficiency, affecting production continuity, and making it difficult to simultaneously remove both large and small particles, leading to insufficient filtration precision. Furthermore, they are inconvenient to disassemble and maintain during use, increasing the workload of staff. Utility Model Content

Through the filter media mechanism, it achieves multi-stage filtration of dairy products, thereby improving filtration accuracy. After the dairy products enter the outer shell, the first drive mechanism pushes the dairy products to flow, passing through the coarse filter component, the connecting component and multiple fine filter components in sequence. At the same time, it drives the multiple fine filter components to rotate, which disperses and filters the dairy products, reduces clogging, and improves filtration efficiency.

[0017] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0018] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention: an impurity filtration device for dairy processing.

[0019] like Figures 1-3 As shown, the impurity filtration device for dairy processing according to this utility model embodiment may include a base 1, a housing 2, and a filter media mechanism 3.

[0020] The outer shell 2 is movably connected to the base 1, and the outer shell 2 is provided with a feed pipe 21 and a discharge pipe 22.

[0021] It should be noted that the base 1 can stably support the outer shell 2 and the filter material mechanism 3. The outer shell 2 is detachably mounted on the base 1, and the upper part of the base 1 is set with a flip-top structure. The continuous inflow and outflow filtration of dairy products is realized through the feed pipe 21 and the discharge pipe 22.

[0022] The filter media mechanism 3 includes a coarse filter assembly 31, at least two connecting assemblies 32, at least two fine filter assemblies 33, and a first drive mechanism 34.

[0023] The first drive mechanism 34 is disposed on the base 1, and at least two fine filter components 33 are disposed on the first drive mechanism 34. The at least two fine filter components 33 are disposed on the coarse filter component 32 through at least two connecting components 32 and are in contact with the outer shell 2.

[0024] It should be noted that the fine filter assembly 33 rotates below the coarse filter assembly 31 via the connecting assembly 32 and is connected to the coarse filter assembly 31. Furthermore, the first drive mechanism 34 enables at least two fine filter assemblies 33 to rotate synchronously, thereby achieving dispersed filtration of dairy products and reducing clogging.

[0025] Specifically, during the actual filtration production process of dairy products, relevant personnel bolted and fixed the base 1, and connected the feed pipe 21 and the discharge pipe 22 to the dairy production line respectively. In the initial state, each component remained stationary, and the first drive mechanism 34 was powered on.

[0026] During filtration, dairy products enter the outer casing 2 through the feed pipe 21 and undergo initial filtration through the coarse filter assembly 31 to remove larger impurity particles. Then, they are dispersed into the fine filter assembly 33 through the connecting assembly 32. The first drive mechanism 34 synchronously drives multiple fine filter assemblies 33 to rotate, enabling the fine filter assemblies 33 to centrifuge and filter the dairy products, thereby improving filtration accuracy. The centrifuged dairy products are discharged through the discharge pipe 22, effectively improving filtration accuracy, reducing clogging, and simultaneously increasing filtration efficiency while maintaining production continuity.

[0027] During maintenance, the bolts on the base 1 can be removed, the base 1 can be rotated, and the filter media mechanism 3 inside the base 1 and the outer shell 2 can be completely removed for cleaning, which facilitates cleaning and replacement work and reduces the labor intensity of the staff.

[0028] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the first drive mechanism 34 includes a first drive device 341, a stud 342, a sealing plate 343, a drive wheel 344, a plurality of driven rods 345 and a plurality of driven wheels 346.

[0030] It should be noted that the first driving device 341 proposed in the above embodiment adopts a rotary motor, which drives the stud 342 to rotate. At the same time, the rotation of the driving wheel 344 and the multiple driven wheels 346 and driven rod 345 meshing with it drives the fine filter assembly 33 to rotate. The sealing plate 343 is fixedly connected to the base 1 to seal the driving wheel 344 and the multiple driven wheels 346 on the base 1 to avoid contamination of dairy products. At the same time, the sealing plate 343 is threadedly connected to the outer shell 2, and together with the sealing gasket, it achieves bottom sealing treatment of the outer shell 2.

[0032] The partition 312 is movably connected to the outer shell 2 via a sealing ring 313. The first filter screen 311 is disposed on the partition 312 and forms a filter chamber 3111 between the first filter screen 312 and the partition 312. The support cylinder 314 is disposed between the partition 312 and the sealing plate 343 and is located outside the stud 342.

[0033] It should be noted that the center of the partition 312 is recessed to support the first filter screen 311. At the same time, the sealing ring 313 is attached to the inner wall of the outer shell 2, so that the partition 312 has an isolation function. When the dairy product passes through the first filter screen 311, it enters the filter chamber 3111 and waits for the switch valve 322 to open and flow into the fine filter assembly 33.

[0034] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the connecting assembly 32 includes a connecting pipe 321, a switching valve 322, and a rotary joint 323.
