Pump station water inlet runner

Abstract

The invention relates to the technical field of pump stations, and discloses a pump station water inlet runner which comprises a shell, a water inlet runner is formed in the shell, a filter plate is fixedly mounted on the inner wall of the shell, conical filter holes are uniformly formed in the filter plate, and the inner diameters of the conical filter holes are gradually reduced from left to right; impurities filtered by the filter screen are all located between the filter plate and the filter screen, when water flow flows in the water inlet flow channel, the filter screen is pushed to drive the sealing plate to move, the sealing plate moves to enable slag discharging holes formed in the sealing plate to be staggered with slag discharging holes in the inner bottom wall of the water inlet flow channel, and therefore the slag discharging holes can be blocked through the sealing plate; when water flow does not flow in the water inlet flow channel, the filter screen is located at the original position, the slag discharging hole formed in the sealing plate coincides with the slag outlet hole in the inner bottom wall of the water inlet flow channel, at the moment, impurities slowly precipitate, and therefore the impurities can enter the collecting box through the slag discharging hole, the slag outlet hole and the bottom pipe, and the filtered impurities are automatically discharged.

Description

technical field [0001] The invention relates to the technical field of pumping stations, in particular to a water inlet flow channel of a pumping station. Background technique [0002] With the development of science and technology, nuclear power and other related technologies have become more and more mature and have played a huge role in various fields; among them, nuclear power plants are an efficient use of nuclear power; nuclear power plants use nuclear reactors to replace the boilers of thermal power plants, and use nuclear fuel Special forms of "burning" occur in nuclear reactors to generate heat, which converts nuclear energy into thermal energy to heat water to produce steam; [0003] In a nuclear power plant, the nuclear power plant pump station provides water sources for its downstream cooling and other related systems. In order to ensure the purity of the water source and prevent the blockage of dirt, it is necessary to filter the seawater entering the upstream o...

[0004] Although the above filtering methods can effectively filter out most of the sundries, we have found that there are still some shortcomings in practical applications. For example, the above filtering methods are still not thorough enough to filter the water source, not only difficult to remove Some small-volume debris, and the filter load on the subsequent drum filter is also relatively large, and it is easy to overload and stop due to the large filter load;
