Description

Technical Field

[0001] The present invention relates to the technical field of filters, and more particularly to a conical filter with a multi-layer sintered mesh composite structure. Background Art

[0002] The conical filter with a multi-layer sintered mesh combined structure is mainly formed by superimposing multiple layers of sintered mesh to increase the compressive strength. In terms of filtering solid particle impurities in the liquid, its main function is to improve the cleanliness and quality of the liquid, and can effectively intercept and remove solid particle impurities in the liquid.

[0003] In the existing public documents, the patent with patent announcement number CN204815832U discloses a conical filter. This technology uses a fiber rope as the filter material in the conical filter, and the two ends of the fiber rope are fixed to the upper and lower ends of the conical filter. When filtering sewage, the sewage passes through the rope-like fibers, and the conical structure allows the rope-like fibers to form a continuous gradient density filter layer. Compared with the traditional use of particle filter filters, the amount of particulate matter intercepted is large, while the water quality of the effluent can be guaranteed, the filtration efficiency is higher, the filter material utilization rate is also improved, and there is no problem of filter material loss during backwashing. However, this technology still has the following defects.

[0004] When a conical filter with a multi-layer sintered mesh composite structure is used for filtering, it is necessary to filter through multiple holes on the cone of its outer wall. During the filtering process, since the conical filter has multiple filtering holes at different positions, but the filtering hole sizes of the multiple filtering holes are all fixed sizes, it is difficult to synchronously adjust the filtering sizes of the multiple filtering holes on the conical filter. Therefore, the conical filter is difficult to apply to filtering operations on solid particles of different finenesses, and the adjustable filtering applicability is poor. For this reason, a conical filter with a multi-layer sintered mesh composite structure is required. Summary of the invention
