Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to an easy-to-clean and regenerate filter cloth. Background Technology

[0002] Filter cloth used in filter presses is a key filtration medium in the filtration process, directly affecting filtration efficiency, filter cake moisture content, and equipment operational stability. Filter cloth is mainly woven from natural or synthetic fibers, featuring high filtration accuracy, corrosion resistance, and tensile strength. Filter cloth includes monofilament filter cloth, multifilament filter cloth, and non-woven fabrics, suitable for various media and applications.

[0003] In practical use, the filter cloth adheres to the filter plate. After the mixed slurry enters the filtration chamber, a pressure difference is formed on both sides of the filter cloth, allowing the filtrate to pass through the cloth quickly while trapping the filter residue on the other side, thus achieving solid-liquid separation. During this process, under the influence of a large pressure difference, the filter residue will adhere tightly to the filter cloth. Due to the friction and pressure between the filter cloth and the filter residue, residue may sometimes remain on the cloth. Prolonged, stubborn residue makes the filter cloth difficult to clean, reducing subsequent filtration efficiency and shortening its lifespan. Filter cloth that is difficult to clean thoroughly cannot be reused. Therefore, there is room for technological improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problem that long-term stubborn residues can make filter cloth difficult to clean and reduce subsequent filtration efficiency, by providing an easy-to-clean and regenerable filter cloth.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an easy-to-clean and regenerable filter cloth, including a filter cloth body and a connector; the filter cloth body is fixed to the outside of the filter plate by the connector; the filter cloth body includes filter cloth one and filter cloth two, and both filter cloth one and filter cloth two are provided with a circular groove in the middle.

[0006] Both filter cloth one and filter cloth two consist of a base layer, an intermediate layer, a surface layer, and a protective layer from the inside out. The base layer is made of high-strength polyester monofilament, the intermediate layer is made of elastic fiber woven material, and the surface layer and protective layer are coated with a hydrophobic material. Multiple protective layers are provided and are detachably connected to filter cloth one and filter cloth two.

[0007] Furthermore, the longitudinal section of the connector is I-shaped; the connector includes a hollow cylinder, both ends of which extend from filter plates and are provided with annular plates, and the opposite sides of the annular plates are provided with Velcro 1; the inner side of the circular groove is provided with annular connecting parts, and the opposite sides of the connecting parts are provided with Velcro 2 corresponding to Velcro 1.

[0008] Furthermore, both filter cloth one and filter cloth two are provided with several connecting holes along the circumference, and are connected to the filter plate through the connecting holes and the binding strap.

[0009] Furthermore, the surface of the surface layer and the protective layer are coated with a PTFE coating.

[0010] Furthermore, the surface layer is divided into four areas, each area is sewn with a rectangular Velcro strip three, and the back of the protective layer is provided with Velcro strip four corresponding to the Velcro strip three along the circumferential direction.

[0011] Furthermore, the surface of the protective layer is pressed with anti-slip texture.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] The layered composite structure improves the strength and durability of the filter cloth, and the surface is coated with a hydrophobic coating to reduce the adhesion between the filter cloth body and the cake, making the cake easier to remove, reducing the impact of friction on the filter cloth body, and making subsequent cleaning easier and reducing maintenance difficulty.

[0014] The outer surface is equipped with a removable modular protective layer to resist pressure differential. After prolonged use and damage, the corresponding protective layer can be replaced, which facilitates maintenance, reduces costs, and extends the service life of the filter cloth body.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Example 1, in conjunction with Appendix Figure 1 , 2 3. An easy-to-clean and regenerable filter cloth includes a filter cloth body and a connector 1. The filter cloth body is fixed to the outside of the filter plate by the connector 1. Specifically, the longitudinal section of the connector 1 is I-shaped. The connector 1 includes a hollow cylinder 2, both ends of which extend out of the filter plate and are provided with annular plates 3. The opposite sides of the annular plates 3 are fixed to the central hole of the filter plate, and the opposite sides of the annular plates 3 are provided with Velcro 4. The filter cloth body is provided with annular connecting parts in the middle and near both sides. The opposite sides of the connecting parts are provided with Velcro 6 corresponding to Velcro 4. Thus, when installing the filter cloth body, it is not necessary to insert one of the filter cloths into the hole of the filter plate. Instead, the two layers of filter cloth can be directly fixed by the pre-fixed connector and the Velcro 4 on the outside.

[0023] The filter cloth body includes filter cloth 7 and filter cloth 8. Both filter cloth 7 and filter cloth 8 have a circular groove 5 in the middle. Velcro 2 6 is located on the inner side of the circular groove 5 and is used to connect with Velcro 4 on connector 1.

[0024] Combined with appendix Figure 1 , 2 Both filter cloth 7 and filter cloth 8 have several connecting holes 9 along the circumference, and are connected to the filter plate through the connecting holes 9 and the binding strap; thus fixing the filter cloth body 1 so that it can withstand the pressure difference during filtration.

[0025] Combined with appendix Figure 4 , 5 Both filter cloth 7 and filter cloth 8 consist of a base layer 10, an intermediate layer 11, a surface layer 12, and a protective layer 13, arranged from the inside out. Specifically, the base layer 10 is made of high-strength polyester monofilament, ensuring structural strength and preventing damage from prolonged pressure differential. The intermediate layer 11 is made of elastic fiber woven material, which can withstand deformation to a certain extent and assist in the removal of the filter cake. The surface layer 12 and the protective layer 13 are coated with hydrophobic materials. Specifically, the surface layer 12 and the protective layer 13 are coated with a PTFE coating, which reduces the adhesion between the filter cloth body and the filter cake, making it easier for the filter cake to fall off, reducing the impact of friction on the filter cloth body, and facilitating subsequent cleaning and reducing maintenance difficulty.

[0026] Combined with appendix Figure 1 , 2 The protective layer 13 has multiple layers and is detachably connected to filter cloth 7 and filter cloth 8. Specifically, the surface of the surface layer 12 is divided into four areas, each area is sewn with a rectangular Velcro 3 14, and the back of the protective layer 13 is provided with Velcro 4 15 corresponding to Velcro 3 14 along the circumference. After long-term use and damage, the corresponding protective layer 13 can be replaced, which is convenient for maintenance, helps to reduce costs, and extends the service life of the filter cloth body.

[0027] In addition, the protective layer 13 has anti-slip textured surfaces to reduce the adhesion area of ​​the slag cake, making it easier to detach. It also facilitates subsequent cleaning of the filter cloth body, and residual slag can be easily cleaned by high-pressure water or rinsing.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
