A Garbage Filtration and Circulation System for Rainwater Outlets that Can Be Replaced Conveniently

Abstract

The invention discloses a gutter inlet garbage filtering and circulating system convenient to replace, and relates to the field of urban road drainage facilities. The gutter inlet garbage filtering and circulating system comprises a drainage well, a well lid base on a drainage well mouth, a well lid embedded into and covering the well lid base and a filtering device arranged below the well lid. Drainage holes are formed in the well lid. Filter holes are formed in the filter device. A filter device comprises a flow guiding gasket and a filtering gasket. The flow guiding basket comprises a flow guiding plate and baffles. The flow guiding plate is arranged in an inclined mode, and the lowest side edge of the flow guiding plate is a guiding inlet and connected to the upper edge of one side edge of the filtering basket. The other edges, except the side edge of the guiding inlet, of the flow guiding plate protrude upwards to form the baffles. The filter holes are formed in the upper portion and the bottom face of the side wall of the filter basket, the section, with no filter holes, of the lower portion of the side wall forms a containing cavity capable of storing objects, and the filtering device is stably placed into the drainage well through a placement structure. The gutter inlet garbage filtering and circulating system has the advantages of being practical, good in filtering effect, convenient to assemble and disassemble, stable in structure and the like, and particularly suitable for large displacement.

Description

[0001] The patent application of the present invention is a divisional application of Chinese patent application number 201510336464.4, the original application number is 201510336464.4, the application date is June 17, 2015, and the invention name is Yushuikou Garbage Filtration Circulation System. technical field [0002] The invention relates to the field of drainage facilities for urban roads, in particular to a waste filtering circulation system for rainwater outlets that can filter leaves, gravel, plastic bags and other waste materials and can be cleaned. Background technique [0003] Existing municipalities set up the drainage outlets of urban roads, which are common on the road and connect the underground drainage pipes. The underground drainage pipes are discharged. Such drainage facilities can be said to be only used for drainage, and basically have no effect on filtering garbage and sundries.

Problems solved by technology

[0003] Existing municipalities set up the drainage outlets of urban roads, which are common on the road and connect the underground drainage pipes. The underground drainage pipes are discharged. Such drainage facilities can be said to be only used for drainage, and basically have no effect on filtering garbage and sundries. Because the drainage holes on the manhole cover are designed to achieve fast drainage and not easy to block, the setting of the drainage holes is general. If the manhole cover is used to filter and isolate garbage, it can only filter some bulky substances that cannot be deformed and flowed. For substances such as leaves and plastic bags, even if they are large, they are easy to flow out of the drain hole with the water flow. Into the underground drainage pipes, these things that cannot rot or degrade quickly, as well as unfiltered sand and gravel, etc., can easily cause accumulation in the underground drainage pipes, making the flow rate of the drainage pipes smaller, and slowly It also causes blockage, which cannot be cleared after the blockage, so when it rains, there will often be urban waterlogging and serious water accumulation on the road, and even the road facilities that were originally used for drainage, but the manhole cover is flushed by water pressure due to poor drainage It is a big safety hazard because it is away from the drain, and a large part of the reason is that it failed to filter out the clogged leaves, sand, plastic bags and other garbage substances during drainage.

[0004] Aiming at the problem of filtration, there is also a solution now. Set up a basket or basket for filtration under the manhole cover. It will flow into the filter basket or basket under the manhole cover for re-filtering. This kind of filtering can only filter some substances such as leaves, plastic bags, etc., and fine sand and gravel will still flow out through the filter holes. Underground drainage pipes cause accumulation and blockage, and such filtration methods are very mixed, and the filter basket or basket will be filled quickly, and if it is not cleaned in time, it will cause poor drainage
