Embodiment 1

[0023] refer to figure 1 , a self-draining type deodorizing manhole cover, comprising a concrete layer 1 and a sewage well 2 arranged on it, the top of the sewage well 2 is equipped with a horizontally placed manhole cover 3, and the top of the manhole cover 3 is provided with a water inlet 4 along the radial direction,

[0024] Further, refer to figure 1 , The upper surface of the well cover 3 is provided with a slope, and the height of the slope increases from the water inlet 4 to the surrounding of the well cover 3.

[0025] The bottom end of the well cover 3 is fixedly connected with a semicircular stop piece 6, which is sealed with the well cover 3. The stop piece 6 plays the role of water storage. By increasing the sewage in the stop piece 6, the float 8 is further increased. Discharging the gravity of the water makes the gravity of the float 8 balance and float with the buoyancy of the sewage, and then the sewage is discharged through the water outlet 71 .

Abstract

The invention discloses a self-dredging type deodorant well lid. The self-dredging type deodorant well lid comprises a concrete layer and a drain well arranged on the concrete layer, the top end of the drain well is provided with a well lid body horizontally arranged, a water inlet is formed in the top end of the well lid body in the radial direction, the bottom end of the well lid body is fixedlyconnected with a blocking piece of a semi-circular structure, the blocking piece and the well lid body are arranged in a sealed manner, a placement plate is fixedly connected to the middle of the bottom end of the blocking piece, a draining opening of a round structure is formed in the placement plate, a floater is arranged on the draining opening, and a hollow round structure is adopted in the floater. The blocking piece of the semi-circular structure is arranged at the bottom end of the well lid body, the blocking piece and the well lid body are arranged in a sealed manner, the blocking piece achieves the water storage effect, gravity of the floater and buoyancy of sewage are balanced, the floater can float, the sewage can pass through the drain opening to be drained, under the normal state, according to the gravity, the floater falls on the draining opening in the placement plate, and the transmission path of malodorous gas like hydrogen sulfide in a sewer to the ground can be effectively blocked.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a self-draining type anti-odor manhole cover. Background technique [0002] The foul smelling substance in the sewer is mainly hydrogen sulfide. There is a special obligate anaerobic bacterium in the slime formed by attaching to the wall of the sewer pipe. This bacterium is mainly a sulfate-reducing bacterium, which reduces the sulfate organic matter in the sewage under anaerobic conditions to form sulfur hydrogen. This free gas is released into the atmosphere and produces a foul odor. Hydrogen sulfide is generally the product of certain chemical reactions and natural protein decomposition processes, and is a component of certain natural substances that exists in various production processes and in nature. Such as mining and extraction of copper, nickel, cobalt and other heavy metals from ores, especially from sulfide ores, low-temperature coking of coal, mining and...
