Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more particularly to an impact-proof filter structure. Background Art

[0002] Small precision filter is a kind of equipment used for filtering. It has the characteristics of high filtering accuracy, compact structure and diverse materials. It has a wide range of uses, including but not limited to the following fields: Food industry: filtering impurities in food; Wine industry: improving the purity of wine; Pharmaceutical and chemical industry: ensuring the purity of materials in the production process.

[0003] Currently, most small precision filters on the market have flat bottoms. In actual use, this type of precision filter often has a flat bottom and improper operation often causes water hammer to lift the bottom plate, making the filter easily damaged when impacted, affecting its use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an impact-proof filter structure.

[0005] In order to solve the above-mentioned background technical problems, the present invention adopts the following technical solutions:

[0006] The impact-proof filter structure comprises a filter cylinder, wherein a convex bottom plate is provided at the bottom of the filter cylinder, and a reinforcing iron plate is welded to the bottom of the convex bottom plate.

[0007] As a further description of the above technical solution: the convex bottom plate is conical, and the surface of the convex bottom plate is provided with a plurality of reinforcing ribs extending from the apex of the cone along the inclined surface to the edge.

[0008] As a further description of the above technical solution: the reinforced iron plate includes an annular plate adapted to the bottom diameter of the convex bottom plate, and a cross or Pozigzag support plate integrally formed therewith is provided in the annular plate.

[0009] As a further description of the above technical solution: all the reinforcing ribs are evenly distributed, and the shapes of the reinforcing ribs are straight, curved or wavy structures.

[0010] As a further description of the above technical solution: the surface of the reinforced iron plate is coated with a wear-resistant coating, and the thickness of the wear-resistant coating is 0.5-2 mm.

[0011] Compared with the prior art, the advantages of the present invention are:

[0012] In order to meet the actual use needs and versatility, this solution proposes a new installation method for the flat-bottom precision filter base plate. The base plate is made into a convex surface and fixed with an iron plate, which can significantly improve the impact resistance of the filter and ensure its stable operation under harsh working conditions.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-3 The impact-resistant filter structure includes a filter cylinder 1, a convex bottom plate 2 is provided at the bottom of the filter cylinder 1, and a reinforced iron plate 3 is welded to the bottom of the convex bottom plate 2. By changing the traditional flat bottom plate to a convex surface and installing the convex bottom plate 2 on the filter cylinder by welding, when a water hammer impact occurs, the convex bottom plate 2 can disperse the impact force and reduce the concentrated pressure on a single point of the bottom plate. Welding the reinforced iron plate 3 on the convex bottom plate 2 can further enhance the strength and rigidity of the bottom plate. The reinforced iron plate 3 can provide additional support to prevent the bottom plate from deforming when impacted, significantly improving the impact resistance of the filter.

[0020] The convex base plate 2 is conical in shape and is provided with a number of reinforcing ribs 4 extending from the apex of the cone along the slope toward the edge. The evenly distributed ribs 4 effectively disperse impact forces and reduce concentrated pressure on the base plate. All ribs 4 are evenly distributed and can be straight, curved, or wavy. Furthermore, a rubber pad can be placed at the apex of the cone on the convex base plate 2 to absorb and disperse impact forces.

[0021] The reinforcement plate 3 comprises an annular plate 31, adapted to the diameter of the bottom of the convex base plate 2. An integral cross or Pozi support plate 32 is positioned within the annular plate 31, further enhancing the base plate's rigidity and stability. The surface of the reinforcement plate 3 is coated with a wear-resistant coating made of ceramic or a polymer composite material, with a thickness of 0.5-2 mm. This coating not only improves the wear resistance of the reinforcement plate 3 but also effectively absorbs and disperses impact forces, minimizing damage to the base plate.

[0022] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
