Abstract
Description
Technical Field
[0001] This application relates to the field of filtration technology, and in particular to a filter assembly and a kitchen waste treatment device. Background Technology
[0002] In the treatment processes of food waste, kitchen waste, and municipal sludge, the most common and effective technical solution to achieve solid-liquid separation between residual liquid wastewater and solid matter in the materials to be treated is squeeze filtration, which involves squeezing out the residual liquid wastewater through a metal filter screen.
[0003] In existing extrusion filtration technology, there are two common types of metal filter screens:
[0004] One type is a cylindrical structure with an integrated metal filter screen;
[0005] One approach is to make the filter screen into a split structure to facilitate the handling of filter screen blockage, make it easier to clean the filter screen, and reduce the overall replacement cost and disassembly and maintenance difficulty of the filter screen components. That is, the filter screen is made into a short-length cylinder according to the required size space, and perforated flanges are set at both ends to connect it to the end face of the extrusion filter equipment shell with bolts.
[0006] The above two structures have the following shortcomings and defects in practical applications:
[0007] The first type of structure, although the overall drainage area is large enough, requires the entire device to be disassembled to replace it if the filter screen is partially damaged. This is difficult to operate and the material cost is high.
[0008] The second construction, while reducing material costs by making the filter into a shorter cylindrical shape, has the following drawbacks:
[0009] 1. Disassembly requires removing the entire outer casing of the extrusion filter, which is inconvenient.
[0010] 2. A connecting flange is required on the end face of the filter screen, and the flange is not a standard fixed size and needs to be custom-made, which incurs additional costs;
[0011] 3. Because bolted connections are used, there are certain technical requirements regarding the strength and quantity of bolts. During disassembly, each bolt needs to be removed individually, and sufficient operating space must be ensured, making it inconvenient. Utility Model Content

[0038] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.
[0039] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.
[0040] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0041] To facilitate understanding of the filter assembly and food waste treatment equipment provided in this application embodiment, their application scenarios will be explained first. The filter assembly and food waste treatment equipment provided in this application embodiment are used to reduce the filter area, thereby reducing material costs. In existing extrusion filtration technology, there are two common types of metal filter structures: one is a one-piece cylindrical structure; the other is a split structure, made to facilitate handling filter clogging, easy cleaning, and reduce the overall filter component replacement cost and disassembly / maintenance difficulty. In this split structure, the filter is made into a shorter cylinder according to the required size space, with perforated flanges at both ends for bolt connection to the end face of the extrusion filtration equipment housing. The above two structures have the following shortcomings and defects in practical applications: The first structure, although having a large overall drainage area, requires complete disassembly of the entire device for replacement when the filter screen is partially damaged, making operation difficult and increasing material costs. The second structure, while making the filter screen into a shorter cylinder can reduce material costs, has the following drawbacks: 1. Disassembly requires removing the entire outer shell of the extrusion filter, which is inconvenient; 2. The filter screen end face requires a connecting flange, and the flange's non-standard fixed size necessitates custom processing, incurring additional costs; 3. Because bolted connections are used, there are certain technical requirements regarding bolt strength and quantity. Disassembly requires removing each bolt individually while ensuring sufficient operating space, making it inconvenient. Therefore, this application provides a filter screen assembly and a kitchen waste treatment device to reduce the filter screen area and thus lower material costs. The following detailed description, in conjunction with specific accompanying drawings, illustrates these embodiments.
[0042] refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the structure of the first filter unit provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of the second filter unit provided in an embodiment of this application; Figure 3 This is a schematic diagram of the positioning ring provided in an embodiment of this application; Figure 4 This is a schematic diagram of the structure of the edge strip provided in an embodiment of this application; Figure 5 A schematic diagram of the installation structure of the first filter unit provided in an embodiment of this application; Figure 6 This is a schematic diagram of the installation structure of the second filter unit provided in an embodiment of this application.
[0043] exist Figures 1 to 6 In this application embodiment, a filter assembly is provided, including: a first filter unit and a second filter unit, wherein,
[0044] The first filter unit is used for preliminary filtration of materials;
[0045] The second filter unit is used to filter the extruded material;
[0046] Both the first filter unit and the second filter unit include at least one filter body.
[0047] In the above technical solution, by setting a first filter unit and a second filter unit, the first filter unit is used to perform preliminary filtration of materials; the second filter unit is used to filter materials that have undergone extrusion processing; both the first filter unit and the second filter unit include at least one filter body; the filter area is reduced, thereby reducing material costs.
[0048] Specifically, by setting up a first filter unit and a second filter unit, this design brings several advantages to the material handling process, including:
[0049] Cost savings: By using an appropriate amount of filter area at each stage, this design significantly reduces the total filter area compared to a single large filter. This not only reduces the cost of filter materials but also decreases the frequency of filter replacement and maintenance costs. Furthermore, the reduced filter area allows for a corresponding reduction in the overall size of the equipment, thus saving installation space and transportation costs.
[0050] Improved filtration efficiency: Due to the reasonable distribution of filter area, processing interruptions caused by filter clogging are reduced, improving the continuity and stability of the production line.
[0051] Flexibility and scalability: This phased filter design makes the system easier to adjust to material characteristics and processing requirements. For example, the filter pore size can be adjusted based on the particle size distribution of the material, or the number of filter units can be increased or decreased based on the throughput. As production scales up or material characteristics change, the system can be easily expanded or optimized to adapt to new production needs.
[0052] In one specific implementation scheme, the filter body includes a positioning ring 1, a filter screen 3, and side strips 2, wherein,
[0053] The positioning ring is connected to both ends of the filter screen.
[0054] The edge strip is connected to both sides of the filter screen, and the edge strip is connected to the positioning ring.
[0055] In one specific implementation, the positioning ring is a quarter ring or a half ring.
[0056] In one specific implementation scheme, the positioning ring is provided with a first connecting through hole.
[0057] In one specific implementation, the edge strip is provided with a second connecting through hole.
[0058] In one specific implementation scheme, a fastener 4 is also included, wherein...
[0059] The fastener is used to fix the filter body.
[0060] In one possible implementation, the fastener is a clamp.
[0061] Specifically, using standard clamps for installation and fixation does not require excessive precision in installation dimensions or operating space, and its overall cost and convenience are superior to existing product structures.
[0062] In one possible implementation, the filter screen is made of carbon fiber material.
[0063] Specifically, the advantages of carbon fiber filters include:
[0064] High-efficiency filtration: The carbon fiber filter is composed of multiple fine carbon fibers forming a mesh structure with tiny pores, which can filter out tiny particles with a diameter of less than 1 micrometer, such as bacteria and viruses.
[0065] Strong adsorption capacity: Carbon fiber filters have excellent adsorption properties, capable of adsorbing various harmful substances such as organic matter, odors, and formaldehyde. Activated carbon fiber filters, in particular, have even stronger adsorption capabilities.
[0066] High durability: Carbon fiber material itself has high strength and corrosion resistance, ensuring a long service life for the filter. This allows carbon fiber filters to maintain stable filtration performance during long-term use, reducing replacement frequency and lowering operating costs.
[0067] High throughput: Carbon fiber filters have high throughput characteristics, which can maintain a large flow rate while ensuring filtration effect, thereby improving treatment efficiency.
[0068] High environmental friendliness: Carbon fiber filters do not release any harmful substances during use and do not cause secondary pollution. This aligns with modern environmental protection concepts, making carbon fiber filters a green and environmentally friendly filtration material.
[0069] In one possible implementation, the first filter unit includes one filter body; the second filter unit includes two filter bodies.

Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this application. Based on this, various substitutions and improvements can be made to this application, all of which fall within the protection scope of this application.
