Description

Self-dredging type odor-stopping well cover

Technical Field

The invention relates to the technical field of drainage equipment, in particular to a self-dredging type odor-stopping well lid.

Background

The main malodorous substances in sewers are hydrogen sulfide. Because the slime attached to the wall of the sewer pipe contains special obligate anaerobic bacteria which are mainly sulfate reducing bacteria, sulfate organic matters in the sewage are reduced under the anaerobic condition to generate hydrogen sulfide. The free gas is released into the atmosphere to generate malodor. Hydrogen sulfide is generally a product of certain chemical reactions and natural decomposition processes of proteins, and is a component of certain natural substances that are present in a variety of production processes and in nature. Such as mining and extracting heavy metals such as copper, nickel, cobalt and the like from ores, particularly from sulphide ores, low-temperature coking of coal, mining and refining of sulphur-containing petroleum, chemical rubber, artificial fiber, papermaking, sulphur dyes, pigments, organophosphorus pesticides and other industrial production waste water contains certain sulfides. This is only a small part of the exhaust system. In municipal sewage systems, both sulfate and organic sulfides in the wastewater may be converted to sulfides under anaerobic conditions. The sulfides are discharged with the wastewater and are often continuously emitted in the form of hydrogen sulfide. After the excrement in the sewer is fermented, a large amount of methane, namely commonly called methane, can be generated. At present, biogas digesters are built in many rural areas. The gas in the sewer is not a single gas but a mixed gas. Is composed of hydrogen sulfide, carbon dioxide, methane, ethane and other gases, has toxicity and is very harmful to human bodies.

In the same way, in the common family life, gas is often leaked from a sewer, the smell is heavy, the living condition is severe, and meanwhile, as the sewage is accumulated in the sewer pipeline for a long time and few people can clean the sewer pipeline, the harmful gas in the pipeline is increased day by day, the sewer pipeline harms the family and becomes a potential safety hazard of the family.

Along with the improvement of people's standard of living and the enhancement of environmental protection consciousness, no matter be harmless gas or the condition is abominable, all let the public endure to bear, and well lid among the prior art is pure reinforced concrete structure usually, effectual separation foul smell when can not dredging sewage.

Disclosure of Invention

The invention aims to solve the problem that in the prior art, a well cover is usually of a simple reinforced concrete structure and cannot effectively block odor while dredging sewage, and provides a self-dredging type odor-stopping well cover.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a from deodorant well lid of mediation formula, includes muddy dirt layer and the bilge well that sets up on it, the well lid that the level was placed is installed on the top of bilge well, the water inlet has been radially seted up on the top of well lid, the bottom fixedly connected with of well lid adopts semi-circular structure's separation blade, the separation blade sets up with the well lid is sealed, the board is placed to the bottom middle part fixedly connected with of separation blade, place and set up the outlet that adopts circular structure on the board, placed the float on the outlet, the float adopts hollow circular structure, the diameter of float is greater than the outlet.

Preferably, a magnet is placed in the inner space of the float.

Preferably, a spring capable of being magnetically attracted by a magnet is installed in the water inlet.

Preferably, the water inlet adopts a rectangular structure, and a circular groove is formed in the middle of the lower end of the water inlet.

Preferably, the upper surface of the well lid is provided with an inclined plane, and the height of the inclined plane is gradually increased from the water inlet to the periphery of the well lid.

The invention has the beneficial effects that:

the separation blade that adopts semi-circular structure is set up in the bottom of well lid, and the separation blade sets up with the well lid is sealed, and the separation blade plays the effect of retaining for the gravity of float and the buoyancy balance of sewage float, and then make sewage see through the outlet and discharge.

The float falls on the water outlet of the placing plate according to the gravity in a normal state, thereby effectively blocking the transmission path of malodorous gases such as hydrogen sulfide and the like in the sewer to the ground.

In addition, inside sewage gets into the separation blade to when further making the float, because the regular range of magnetic pole in the magnetite, when meetting the material spring of parent's magnetism, take place the interact, make magnetite and spring be close to each other, and then make the spring take place to vibrate, the spring can smash, clear up the intraoral silt of intaking owing to inside tension at the compression-in-process that extends, effectually prevents to intake in by impurity such as silt to plug up.
