Description
Technical Field
The invention relates to the technical field of sewage treatment equipment, in particular to a quick opening door structure of an overflow port.
Background
In a large-scale urban sewage treatment plant, the overflow port is directly communicated with a lift pump pit in the original design at the upper part of a coarse grating platform. When the water level of the pipe network is higher than the thick grating, water flows over the thick grating platform, and a large amount of water flows into the lifting pump pit through the overflow port to form large suction. When the thick-grid grab bucket is close to the overflow port, under the combined action of the suction force and the direct impact of the water in the sewage pipe network on the grid, the grab bucket is easily flushed into the overflow port, so that the grab bucket cannot normally work, and the grab bucket is easily damaged. If the water level of the pipe network is kept at a high position for a long time, the grab bucket cannot be used for grabbing the slag intercepted by the grating, so that the grating is seriously blocked, and the water passing amount of the grating is rapidly reduced. A large amount of sewage carrying large-scale slag directly enters the pump pit through the overflow port, so that the lift pump is frequently damaged.
In order to ensure the normal operation of the mobile grab bucket, the overflow port needs a gate device for blocking the sewage from flowing into the pump pit. The gate device is normally in a closed position and needs to be opened quickly to overflow in an emergency where the level difference between the front and rear of the grid is high. Therefore, the gate device must be opened quickly and reliably, and is difficult to realize by adopting the traditional screw lifting gate, and the difficulty points are three: (1) the depth of the overflow port reaches more than ten meters; (2) Because the original design does not consider the sealing of the overflow port, the installation of the gate device is seriously influenced; (3) The lifting stroke required for opening the gate is long, and the full opening speed is slow.
