[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 detachable and washable impurity filtering device for dairy product processing, including a filter tank 1. A top cover 4 is installed on the top surface of the filter tank 1, and a feeding pipe 41 is fixedly connected to the center of the top surface of the top cover 4. A connecting bolt 42 is passed through the top surface of the top cover 4. A filter screen plate 5 is provided inside the filter tank 1. Three filter screen plates 5 are provided. A limiting groove 13 is opened on the inner side wall of the filter tank 1. A guide rod 14 is fixedly connected to the inner wall of the limiting groove 13. The side wall of the filter screen plate 5 is fixed. A limiting block 54 is connected to the inner wall of the limiting groove 13. The limiting block 54 is sleeved on the outer wall of the guide rod 14. A support ring plate 51 is fixedly connected to the top surface of the filter screen plate 5. A sealing ring 53 is fixedly connected to the top surface of the support ring plate 51. A slot 52 is opened on the bottom surface of the support ring plate 51. A receiving hopper 12 is provided inside the filter tank 1. The filter screen plate 5 is installed on the top surface of the receiving hopper 12 through the slot 52. The three filter screen plates 5 are stacked and connected through the support ring plate 51 and the slot 52.

[0019] The specific settings and functions of this embodiment are described below. The top cover 4 is fitted and installed with the filter tank 1 via connecting bolts 42, which not only seals the filtration space but also provides a convenient structural basis for opening the cover as a whole during subsequent disassembly and washing. The feeding pipe 41 on the top surface of the top cover 4 serves as a material input channel. Its centrally fixed and connected design allows dairy products to fall evenly into the internal filtration structure, avoiding uneven filtration caused by local impact. The stacked design of three filter screens 5 achieves graded filtration effects of coarse, medium, and fine filtration, which can sequentially intercept large particulate impurities, medium particulate suspended matter, and fine impurities in dairy products, greatly improving filtration accuracy and meeting the hygiene requirements of dairy product processing. The limiting groove 13 on the inner side wall of the filter tank 1 and the limiting block 54 on the side wall of the filter screen 5 form a fitted and fitting structure, while the guide rod 14 passes through the limiting groove. The interlocking design of block 54 enables bidirectional positioning of the filter screen 5 during installation. It limits horizontal offset via the limiting groove 13 and guides vertical installation via the guide rod 14, ensuring precise alignment of the three filter screens 5 and preventing leakage due to misalignment. The support ring plate 51 on the top surface of the filter screen 5 provides stable support for the upper filter screen 5, preventing deformation due to material pressure. Furthermore, its top sealing ring 53 fills the gaps between adjacent filter screens 5, achieving a seal after stacking and preventing unfiltered dairy products from flowing through the gaps, ensuring thorough filtration. The matching design of the slot 52 on the bottom surface of the support ring plate 51 with the top surface of the receiving hopper 12 and the upper support ring plate 51 forms a stacking and fixing method of slot positioning and ring plate support. This improves stacking stability and simplifies the disassembly and assembly process, allowing for direct upward extraction of the filter screen 5 for separation.

[0020] Example 2: Figure 1 - Figure 4 As shown, the bottom end of the connecting bolt 42 is inserted into the inner wall of the limiting groove 13 and threaded to the top end of the limiting groove 13. The bottom surface of the top cover 4 is fixedly connected to the pressure plate 43, which is pressed against the support ring plate 51 of the top filter screen plate 5. The bottom center of the filter tank 1 is connected to the connecting pipe 31, and the top end of the connecting pipe 31 is sealed and inserted into the bottom surface of the receiving hopper 12. The side wall of the connecting pipe 31 is fixedly connected to the drain pipe 3. The side wall of the filter tank 1 is embedded with a transparent glass plate 11. The bottom surface of the filter tank 1 is fixedly connected to the drain pipe 6. The side wall of the filter tank 1 is fixedly connected to the support rod 2.

[0021] The overall effect of this embodiment is that the bottom end of the connecting bolt 42 is inserted and threaded into the inner wall of the limiting groove 13. Compared with simple top surface fixing, this design combines the fixing point of the top cover 4 with the limiting structure of the filter tank 1, which not only enhances the installation stability of the top cover 4, but also drives the pressure plate 43 to press down and compact the support ring plate 51 of the top filter screen plate 5 through the bolt tightening force, making the stacking and sealing of the three-stage filter screen plates 5 tighter and further eliminating sealing gaps. The top end of the connecting pipe 31 is sealed and inserted into the bottom surface of the receiving hopper 12, and the bottom end is fixedly connected to the drain pipe 3, forming a closed guide. The outlet channel prevents secondary contamination of clean dairy products during the discharge process; the sealed plug design ensures smooth material discharge and facilitates the separation of the receiving hopper 12 from the connecting pipe 31 during disassembly and washing; the transparent glass plate 11 embedded in the side wall of the filter tank 1 enables visual monitoring of the filtration process, allowing operators to observe the accumulation of impurities on the filter screen surface and the flow of materials in real time, and promptly determine whether to stop the machine for cleaning; the drain pipe 6 at the bottom of the filter tank 1 serves as the discharge channel for cleaning wastewater and impurities, preventing cleaning liquid from remaining in the tank, and together with the detachable and washable structure, forms a complete cleaning closed loop.

[0022] The usage and working principle of this device are as follows: First, place the receiving hopper 12 into the preset position inside the filter tank 1; then, align the three filter screens 5 sequentially with the limiting slots 13 and guide rods 14 via the limiting blocks 54, stacking them from top to bottom, so that the slots 52 of the bottom filter screen 5 engage and fix with the top surface of the receiving hopper 12; cover with the top cover 4, insert the connecting bolts 42 through the top cover 4 and thread them to the top of the limiting slots 13, and tighten the bolts to press the pressure plate 43 firmly against the top support ring plate 51; finally, check the valve status of the drain pipe 3 and the sewage pipe 6 to ensure that the sewage valve is closed and the drain valve is open; input the dairy products to be filtered into the filter tank 1 through the injection pipe 41, and the dairy products flow sequentially through three stages under gravity. The filter screen 5 traps impurities on its surface. The filtered clean dairy products fall into the receiving hopper 12 and are discharged to subsequent processing equipment via the connecting pipe 31 and the drain pipe 3. During operation, the accumulation of impurities on the filter screen and the flow of materials are observed through the transparent glass plate 11. When a large amount of impurities are observed to have accumulated on the filter screen surface or the discharge speed has decreased significantly, the feeding is stopped and the drain valve is closed. The connecting bolts 42 are unscrewed, the top cover 4 is removed, and the three filter screens 5 are lifted upwards in sequence to rinse or brush the impurities on the filter screen surface. At the same time, the drain valve can be opened to introduce clean water into the filter tank 1 to rinse the tank wall, and the wastewater is discharged from the drain pipe 6. After cleaning, the filter screens are reinstalled according to the assembly steps and can be put into use again.

[0023] 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 present utility model.
