Multifunctional deodorization device

Abstract

The invention discloses a multifunctional deodorization device. The device comprises a fixing seat, a drain hole, a concave table board, an elastic hard plastic film and a limiting plate; the limitingplate is provided with bolts, and the bolts are fixed on the concave table board. According to the multifunctional deodorization device, the structure is simple and reasonable, the used parts are allmade from common and cheap articles in life, and thereby the production cost of a sewer floor drain is greatly reduced; by adopting the device, sewage and smudginess in a sewer outlet can not be accumulated, the produced pressure presses down the elastic hard plastic film, the elastic hard plastic film is opened, the sewage and the smudginess drop into an urban sewer pipe screen smoothly, and theproblem that a traditional floor drain is blocked easily due to adopting a water seal and S-shaped bend mode is eliminated; when no sewage and smudginess exist in the sewer, the elastic hard plasticfilm is automatically closed to the concave table board of the sewer outlet, the foul smell at the lower portion of the sewer outlet is closed and can not flow out through the sewer outlet, and the deodorization effect is achieved; the multifunctional deodorization device can reduce 30%-40% of the total urban pollutant emissions, and make a contribution to the construction of a saving and green city.

Description

technical field [0001] The invention relates to a multifunctional deodorizing device. Background technique [0002] There are many underground pipe networks in municipal engineering, and the drainage pipe network is its lifeblood, while the drainage inspection well is the window of the drainage pipe network. It communicates the pipeline network and the ground, and plays the role of overhauling pipelines, removing silt, and connecting pipelines in different directions and at different heights. I have been to many cities, and when walking on the sidewalks on both sides of the street, I often smell an indescribable pungent smell, the smell of garbage. Through observation, these pungent and unpleasant smells come from the road The drainage holes on both sides, it is found that these sewers are not equipped with measures to prevent odor and anti-odor flow back, causing the garbage smell in the sewer to return upward from the drainage holes that communicate with each other.

Problems solved by technology

Floor drains are installed at the water pipes of existing urban residential buildings to prevent odors from escaping. However, the existing floor drains are complex in structure, high in cost, prone to blockage, inconvenient to replace and clean, and cannot effectively balance production costs and deodorizing functions. Some sewer pipes set up S-shaped bends and rely on the accumulated water in the S-shaped bends to isolate the odor of the main sewer. However, in this way, after the water seal layer accumulated in the S-shaped bends evaporates, it loses the anti-odor function, and the S-shaped bends The bend is easy to deposit and accumulate dirt, it is not easy to clean, and even clogged
