Abstract
Description
Technical Field
[0001] The utility model relates to a filter, in particular to a complete combined net-type decontamination filter. Background Art
[0002] With the development of centralized heating and the full utilization of energy, the utilization of waste heat from large thermal power plants, namely long-distance pipeline heating, is developing rapidly and moving forward. During the construction of long-distance heating pipelines, construction waste and unexpected debris will fall into the pipelines. These debris will accumulate in the pipelines. During operation, many lightweight waste and debris cannot be discharged, affecting normal heating and damaging equipment. Therefore, filters are needed for water treatment. Currently used water treatment filtration devices generally have two filters. The first coarse filter is a flat-plate filter that is not easy to disassemble and difficult to clean. The second fine filter is usually a large barrel filter. Its disadvantage is that the filtration area is small and the efficiency is low. Summary of the Invention

DETAILED DESCRIPTION
[0021] The accompanying drawings are specific embodiments of the present invention. Figures 1 to 7 As shown, this complete combined mesh-type decontamination filter comprises a vertical cylinder 1, a water inlet pipe 2 is installed at the lower part of the cylinder 1, a water outlet pipe 3 is installed at the upper part, a lower sewage pipe 5 is installed at the lower end of the cylinder 1, and a valve 4 is installed on the lower sewage pipe 5; a manhole 7 is also provided on the cylinder 1.
[0022] A plurality of flange openings 8 are installed at the upper end of the cylinder 1. These flange openings 8 are evenly distributed in an annular manner at the upper end of the cylinder 1. A threaded pipe 9 is welded to the lower end of each flange opening 8. The threaded pipe 9 is threadedly connected to a secondary vertical filter cartridge 6. The secondary vertical filter cartridge 6 is preferably composed of several separate filter cartridges threadedly connected.
[0023] A blocking plate 10 is installed in the cylinder 1. The periphery of the blocking plate 10 is connected to the inner wall of the cylinder 1 to prevent sewage from being discharged directly without filtration. The blocking plate 10 is located below the outlet pipe 3. A through hole 12 is opened on the blocking plate 10 below each flange opening 8. It is best to open a circle of annular groove 11 around the through hole 12. The cross-section of the annular groove 11 is preferably trumpet-shaped. The lower end of the secondary vertical filter cartridge 6 is inserted into the annular groove 11.
[0024] Several transverse plates 13 are installed in the cylinder 1. The transverse plates 13 are located below the sealing plate 10. Both ends of the transverse plates 13 are connected to the inner wall of the cylinder 1. One side of the transverse plates 13 on both sides is the same arc as the cylinder 1. The bottom of the opposite side of the two adjacent transverse plates 13 is stepped. The stepped part is used to insert a primary filter screen 14. Then, an auxiliary plate 15 is hinged on the lower surface of the transverse plate 13. The primary filter screen 14 is fixed to the stepped part by the auxiliary plate 15 and several fasteners 16, that is, the primary filter screen 14 is clamped between the transverse plates 13 and the auxiliary plates 15; all the transverse plates 13 and the primary filter screen 14 form a circle in contact with the inner wall of the cylinder 1.
[0025] The first-level filter screen 14 is preferably 4-6 pieces.
[0026] The fastener 16 can be a bolt, preferably a butterfly bolt, which is easy to operate.
[0027] The transverse plate 13 is located above the water inlet.
[0028] The working process is as follows: During the operation of the utility model, sewage enters from the water inlet pipe 2. Since the plane of the primary filter screen 14 is parallel to the direction of water flow, the water flow will not cause a strong impact on the primary filter screen 14, thereby reducing the impact damage of the primary filter screen 14 and extending the service life. After the primary filter screen 14 filters the large debris and impurities, the sewage enters the secondary vertical filter cartridge 6 through the through hole 12 and is discharged from the outlet pipe 3 after being filtered. When the filter screen needs to be cleaned, the utility model stops running, and the maintenance worker enters from the manhole 7 to fasten the fastener 1. 6 is unscrewed, and the primary filter screen 14 can be removed for cleaning; after removing the flange port 8 and lifting it up to a certain height, hold the secondary vertical filter cartridge 6, remove the flange port 8, and lift the secondary vertical filter cartridge 6 upward until one discrete filter cartridge is completely separated from the cylinder body 1, remove the discrete filter cartridge, and then remove the other discrete filter cartridges in the same way until all the discrete filter cartridges are lifted up. After one flange port 8 is removed, remove the next flange port 8, and until the secondary vertical filter cartridges 6 of all flange ports 8 are removed, they can be cleaned.
[0029] Except for the technical features described in the specification, the remaining technical features are known to those skilled in the art.
