Description

Technical Field

[0001] The utility model relates to the technical field of separating sheets for filter discs, in particular to a separating sheet for a novel thin-film melt filter disc. Background Art

[0002] A filter disc is a component used in industrial filtration equipment. It consists of a series of flat filtration units that can be stacked together to form a filtration bed. The main function of the filter disc is to remove solid particles, suspended matter, or other contaminants from the fluid. They are widely used in water treatment, chemical industry, food and beverage, pharmaceutical, and other industrial processes to achieve liquid purification and solid-liquid separation.

[0003] Disc filters made of thin-film materials are widely used in industries such as chemical, pharmaceutical, and food for filtering impurities in the melt. However, since the thin-film materials are usually very thin, problems such as overlap and misalignment often occur during installation and use, which not only reduces the filtration efficiency but also increases the maintenance cost of the equipment.

[0004] After retrieval, the Chinese patent application number is: CN201822221062.1, which relates to a separating sheet for a novel thin-film melt filter disc. It consists of connecting rods and concentric circular rings; among them, the concentric circular rings are the main body of the device, the parameters of the connecting rods are unified, and the connecting rods are evenly distributed on the outer ring of the concentric circular rings. The separating sheet of the utility model for the thin-film melt filter disc has many advantages such as simple structure, convenient use, good adaptability, low price, increased filtration area, and extended service life of the filter.

[0005] Although the above technical solution can separate adjacent discs, by distributing the connecting rods outside the concentric circular rings, the overall strength is relatively low. During long-term fluid filtration, the impact force of the fluid will act on the connecting rods, which is not only likely to cause damage to the connecting rods but also likely to cause impact on the separating sheet, resulting in friction between the separating sheet and the discs and reducing the service life of the discs. Therefore, we need to propose a separating sheet for a novel thin-film melt filter disc. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a separating sheet for a novel thin-film melt filter disc. The device has a simple structure and is convenient to use. Through the cooperation of the separating sheet, inner ring, outer ring, and connection structure, the device can not only separate adjacent discs, avoid the problem of adjacent discs overlapping, ensure that the filter disc has good filtering ability, but also has high strength and is not easily deformed and damaged due to the impact force during long-term filtration, and has high practical value, so as to solve the problems raised in the above background art.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 , the utility model provides a technical solution:

[0024] The separator of the new membrane melt filter disc includes:

[0025] The separator body 1; the separator body 1 is provided with a circular hole 2, which is of the same specification as the mounting hole on the disc, and the outer ring 5 and the outer ring 6 are provided on the outer side of the separator body 1, the inner ring 5 is attached to the outer wall of the separator, and the inner ring 5 and the outer ring 6 are connected together by a connecting structure;

[0026] The connecting structure includes an upper connecting rod 7 and a lower connecting rod 8, the two ends of which are respectively connected to the outer wall of the inner ring 5 and the inner wall of the outer ring 6. There are multiple groups of upper connecting rods 7 and lower connecting rods 8 equidistantly distributed on the upper and lower sides of the spacer.

[0027] By arranging an inner ring 5 and an outer ring 6 on the outside of the separator body 1, and arranging a connection structure including an upper connecting rod 7 and a lower connecting rod 8 between the inner ring 5 and the outer ring 6, when in use, the separator body 1 is installed between two adjacent groups of discs, and the separator can effectively isolate the two adjacent groups of discs to avoid overlapping of the filtering surfaces of the two groups of discs, thereby ensuring that the filter discs have normal filtering capacity and filtering effect. At the same time, multiple groups of first connecting rods and second connecting rods are respectively arranged on both sides of the separator body 1, and cooperate with the inner ring 5 and the outer ring 6, so that the device has a high-strength skeleton, which will not be easily damaged under the impact of fluid, and it is not easy to cause displacement and friction of the separator body 1 under the impact of fluid, thereby avoiding damage to the discs caused by friction;

[0028] In general, the device has a simple structure and is easy to use. Through the cooperation of the separator, the inner ring 5, the outer ring 6 and the connecting structure, the device can separate adjacent discs and avoid the problem of overlapping adjacent discs, thereby ensuring that the filter discs have good filtering capabilities. At the same time, it also has high strength and is not prone to structural deformation and damage due to impact force during long-term filtration, and has high practical value.

[0029] It is worth mentioning that see Figure 1-2 :

[0030] The height of the outer ring 6 is half of the height of the inner ring 5, and the upper connecting rods 7 correspond to the lower connecting rods 8. One end of the same set of upper connecting rods 7 and lower connecting rods 8 is connected together and both are located on the inner wall of the outer ring 6. At this time, the outer wall of the inner ring 5 and the same set of upper connecting rods 7 and lower connecting rods 8 form an isosceles triangle.

[0031] Such a design enables, on the one hand, the narrower outer ring 6 to reduce the resistance of the fluid, occupy less space, and facilitate the fluid to contact the disc for filtration; on the other hand, an isosceles triangle is formed between the same set of upper connecting rods 7, lower connecting rods 8 and the outer wall of the inner ring 5, so that the structure of the device has good stability and strength.

[0032] The edge of the outer ring 6 is rounded to reduce the obstruction to the fluid and the impact force of the fluid on the outer ring.

[0033] For further information, see Figure 1 and Figure 3 :

[0034] The upper and lower surfaces of the separator body 1 are both provided with first anti-skid strips 3, which are evenly distributed in multiple groups around the circular hole 2, and are used to prevent sliding and friction between the separator body 1 and the disc. The inside of the circular hole 2 is provided with second anti-skid strips 4, which are evenly distributed in multiple groups around the inner wall of the circular hole 2, and are used to prevent the separator body 1 from rotating.

[0035] By providing the first anti-skid strips 3 on both the upper and lower surfaces of the separator body 1, when the separator body 1 is installed between adjacent discs, the first anti-skid strips 3 on both sides of the separator body 1 respectively contact the discs on both sides, thereby achieving a good anti-skid effect, preventing the separator body 1 and the disc from sliding and rubbing easily, and preventing the disc from being damaged by friction;

[0036] By setting a second anti-slip strip 4 in the circular hole 2, when the separator body 1 and the disc are both installed on a pipe or a fixed rod, the second anti-slip strip 4 can prevent the separator body 1 from easily rotating, such as under fluid impact, and further avoid damage to the disc.

[0037] Among them, the material of the first anti-slip strip 3 and the second anti-slip strip 4 is set to be polyurethane rubber, which has excellent wear resistance, high strength and good elasticity in the hardness range of Shore A60 to Shore A70, good cushioning and shock absorption, the higher the vibration frequency, the greater the energy absorption, good oil resistance and chemical resistance, low affinity with non-polar mineral oil, almost no corrosion in fuel oil and machine oil, high friction coefficient, and can also be replaced with nitrile rubber material according to actual conditions.

[0038] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
