Description

Technical Field

[0001] This utility model relates to the technical field of filter disc equipment, specifically to stacked melt filter discs. Background Technology

[0002] A filter disc is a component used in industrial filtration equipment. It consists of a series of flat filter units that can be stacked together to form a filter bed. The main function of a filter disc is to remove solid particles, suspended solids, or other contaminants from a fluid. During operation, the liquid to be treated flows through the pores of the filter disc, and solid particles are trapped on the disc surface. As the filtration process continues, the accumulated solids gradually clog the pores, causing the pressure to rise. When a preset pressure threshold is reached, the filter disc is backwashed to remove the accumulated solid particles and restore its filtration capacity. Backwashing is typically achieved by reverse flow of clean liquid or gas to flush away the clogging particles. They are widely used in water treatment, chemical, food and beverage, pharmaceutical, and other industrial processes to purify liquids and separate solids from liquids. Due to their high efficiency and ease of maintenance, filter discs are suitable for applications requiring continuous filtration and backwashing. For example, they can be used in the primary or secondary filtration stages of water treatment plants, liquid purification in the chemical industry, or liquid clarification in the food and beverage industry.

[0003] The existing stacked melt filter discs are inconvenient for workers to replace, and the operation is cumbersome, time-consuming and labor-intensive, thus increasing the workload of workers. Therefore, we need to propose a stacked melt filter disc. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] Stacked melt filter discs, including:

[0028] Disc 2 and fixing tube 1 for mounting disc 2; Disc 2 is sleeved on fixing tube 1, and multiple sets of disc 2 are provided. Multiple sets of threaded sections 11 are provided on fixing tube 1. Positioning rings 12 are threadedly installed on fixing tube 1 through threaded sections 11. Positioning rings 12 are installed on both sides of disc 2. The two sets of positioning rings 12 clamp and position disc 2.

[0029] By fitting a disc 2 onto a fixed tube 1, and providing a threaded section 11 on the fixed tube 1, a positioning ring 12 for positioning the disc 2 is threaded onto the threaded section 11. In actual use, when installing the disc 2, first thread a set of positioning rings 12 onto the fixed tube 1, then fit the disc 2 onto the fixed tube 1, and then thread the next set of positioning rings 12 onto the fixed tube 1. The two sets of positioning rings 12 clamp and fix the disc 2. When it is necessary to disassemble the disc 2, simply remove the positioning rings 12 and the disc 2 in sequence.

[0030] In summary, this device has a simple structure and is easy to use. It installs and positions the disc 2 through the threaded section 11 and the positioning ring 12, enabling quick and convenient installation, use, disassembly, and replacement of the disc 2. It saves time and effort and reduces the tediousness of the work for the staff when replacing the disc 2, thus having high practical value.

[0031] In addition, the positioning ring can separate adjacent sets of discs, preventing the filter surfaces of the discs from coming into contact and causing filter failure, thus ensuring the filtration effect of the discs.

[0032] For further details, please refer to Figure 3 and Figure 5 :

[0033] It also includes a water outlet structure installed on the fixed pipe 1. Multiple sets of water outlet sections 9 are evenly distributed on the fixed pipe 1, with threaded sections 11 located between adjacent water outlet sections 9. Each water outlet section 9 has water outlet holes 10, which are evenly distributed around the outer wall of the water outlet section 9 in multiple sets. A water inlet pipe 3 is located at the center of the disc 2, and multiple sets of water inlet holes 4 are distributed on the water inlet pipe 3. The water inlet pipe 3 is fitted onto the fixed pipe 1, and each set of water inlet pipes 3 corresponds one-to-one with each set of water outlet sections 9.

[0034] When installing disc 2, disc 2 is placed on fixed pipe 1, and the water inlet pipe 3 on disc 2 and the water outlet section 9 on fixed pipe 1 are positioned correspondingly. At this time, water inlet pipe 3 covers water outlet section 9, and external water can only enter the interior of disc 2 after passing through filter surface 7, and enter water outlet section 9 with water outlet hole 10 after passing through water inlet pipe 3 with water inlet hole 4. Then, clean water is discharged through fixed pipe 1. At the same time, impurities are filtered out by filter surface 7.

[0035] This design enables the device to have excellent filtration capabilities and high practical value.

[0036] Additionally, please see Figure 1-4 :

[0037] Both sides of the disc 2 are provided with sealing rings 8, and both ends of the positioning ring 12 are provided with sealing sleeves 13. The sealing rings 8 are sealed and snapped into the inside of the sealing sleeves 13.

[0038] When disc 2 is in place, the sealing rings 8 on both sides of disc 2 fit precisely into the sealing sleeves 13 of the positioning rings 12 on both sides, forming a sealing condition and preventing water from entering the fixed pipe 1 through the gap, further improving the practicality of the device.

[0039] Among them, the sealing ring 8 and the sealing sleeve 13 are made of polyurethane rubber, which has excellent wear resistance, high strength and good elasticity in the Shore A60 to Shore A70 hardness range, good cushioning and shock absorption, and greater energy absorption at higher vibration frequencies. It also has good oil and chemical resistance, low affinity with non-polar mineral oils, and is almost unaffected by fuel oil and machine oil. It has a high coefficient of friction and can be replaced with nitrile rubber or other materials depending on the actual situation.

[0040] The disc 2 has filter surfaces 7 on both sides, and the filter cotton is made of PP cotton material for filtering water. The disc 2 has a collar inside, which is fitted onto the water inlet pipe 3. The collar has a frame 5, and the frame 5 has ring-shaped supports 6 of different sizes on both sides to support the filter surfaces 7. The supports 6 are arranged from high to low from the inside to the outside.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
