Description

Technical Field

[0001] This utility model relates to the field of textile engineering technology, specifically a filter screen for a cocoon boiling tank. Background Technology

[0002] The cocoon boiling process is a crucial step in silk production. The core of this process is to properly dissolve the sericin in the cocoons to facilitate silk reeling. The purity of the liquid in the boiling tank affects the quality of the silk thread and production efficiency. In the early days, the filtering of the boiling tank relied on gauze or metal mesh, which had problems such as low filtration efficiency, easy clogging, and difficulty in cleaning. Later, with the advancement of materials and processes, stainless steel mesh and synthetic fiber mesh were adopted, and innovative designs such as multi-layer composite and adjustable precision filter screens emerged. With the development of intelligent technology, filter screens are moving towards intelligence and modularization.

[0003] Despite significant technological advancements in cocoon boiling tank filters, several pressing issues remain in practical applications. Firstly, filter clogging persists, particularly when processing boiling liquids containing substantial impurities or gelatinous components. This rapid clogging leads to a sharp decline in filtration efficiency, necessitating frequent shutdowns for cleaning or replacement, severely impacting production efficiency and product quality. Secondly, the cleaning and replacement processes for existing filters are often cumbersome, requiring considerable manpower and time, increasing production costs. Furthermore, traditional filter designs often lack flexibility, making it difficult to adjust filtration precision or area according to actual production needs, thus limiting their application in various production scenarios. Therefore, this paper proposes a new filter for cocoon boiling tanks to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a filter screen for a cocoon boiling tank.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a filter screen for a cocoon boiling tank, including a filter screen and a rail frame. There are three filter screens, each consisting of a hollow frame and a solid frame. The solid frame is slidably disposed on the inner wall of the hollow frame. A filter screen is disposed between the hollow frame and the solid frame. A reserved groove is provided on the side of the solid frame. The rail frame includes a T-shaped guide rail. One end of the T-shaped guide rail is provided with two rows of threaded holes, and the other end of the T-shaped guide rail is disposed in the reserved groove.

[0007] Furthermore, the bottom four sides of the hollow frame are provided with slots, and the top four sides of the hollow frame are provided with blocks, with the slots and blocks matching each other.

[0008] Furthermore, the pore size of the filter screen decreases from top to bottom.

[0009] Furthermore, a row of elastic protrusions is provided on both sides of the solid frame.

[0010] Furthermore, a threaded hole is used to connect a miniature ultrasonic transducer.

[0011] Furthermore, the filter screen is wavy.

[0012] This utility model has the following beneficial effects:

[0013] This utility model achieves efficient graded filtration through the structural design of the filter screen, using a three-layer sliding nested filter structure. The sliding cooperation between the hollow and solid frames allows the filter screen to flexibly adjust the filtration gap according to the characteristics of the cocoon material. The three-layer filter screen adopts a gradient pore size design with a larger upper pore and a smaller lower pore, which can effectively separate impurities of different particle sizes. The wavy filter screen structure increases the filtration area and avoids the easy clogging of single-layer filter screens. The graded filtration significantly improves the filtration accuracy.

[0014] This utility model achieves self-cleaning capability through the structural design of the rail frame and the installation of miniature ultrasonic transducers in the threaded holes. Impurities generated during filtration will accumulate on the surface of the filter screen with the water flow, while the high-frequency vibration generated by the ultrasonic waves can continuously peel off the attached substances, prevent the mesh from clogging, reduce the frequency of manual cleaning, and extend the service life of the filter screen.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a filter screen for boiling cocoons, including a filter screen 1 and a rail frame 2. Three filter screens 1 are provided, each including a hollow frame 101 and a solid frame 102. The solid frame 102 is slidably disposed on the inner wall of the hollow frame 101. A filter screen 103 is provided between the hollow frame 101 and the solid frame 102. The aperture of the filter screen 103 decreases from top to bottom, and the filter screen 103 is wavy.

[0023] The filter screen adopts a three-layer nested structure. The adjustable filtration function is achieved through the sliding cooperation of the hollow frame 101 and the solid frame 102. The filter screen 103 is wavy to increase the filtration area. At the same time, the gradient distribution of its pore size from top to bottom forms a graded filtration effect, which can effectively intercept impurities of different particle sizes. The filter screen 103 adopts nano-coating technology to form a superhydrophobic and superoleophilic nano-film on the surface of the filter screen, making it difficult for cocoon shells and impurities to adhere and easy to clean. The sliding of the solid frame 102 on the inner wall of the hollow frame 101 allows users to flexibly adjust the filtration gap according to the characteristics of the cocoon material. The superimposed structure of the three-layer filter screen 1 significantly improves the overall filtration accuracy. The cooperation between the T-shaped guide rail 201 of the rail frame 2 and the reserved groove 104 ensures the stable installation of the filter screen 1, which not only guarantees filtration efficiency but also facilitates disassembly and cleaning.

[0024] The solid frame 102 has a reserved groove 104 on its side and a row of elastic protrusions 105 on both sides. The hollow frame 101 has a slot 106 around its bottom and a block 107 around its top. The slot 106 matches the block 107. The rail frame 2 includes a T-shaped guide rail 201. One end of the T-shaped guide rail 201 has two rows of threaded holes 202. The other end of the T-shaped guide rail 201 is located in the reserved groove 104. The threaded holes 202 are threaded to connect to a miniature ultrasonic transducer.

[0025] The reserved groove 104 on the side of the solid frame 102 is inserted into the T-shaped guide rail 201 to ensure that the filter screen 1 is firmly positioned on the rail frame 2. The elastic protrusions 105 on both sides of the solid frame 102 enhance the friction during sliding and prevent accidental displacement. The slot 106 and the block 107 of the hollow frame 101 form a quick-connect structure between the upper and lower layers, which facilitates the stacking and assembly of multiple layers of filter screens 103. The threaded hole 202 at the end of the T-shaped guide rail 201 is used to install a miniature ultrasonic transducer. The high-frequency vibration generated during operation is transmitted to the entire filter screen 1 through the guide rail. The resonance effect of the elastic protrusions 105 is used to enhance the cleaning effect, effectively prevent the filter screen 103 from clogging, ensure the convenience of modular disassembly and assembly, and achieve efficient and anti-clogging continuous filtration.
