Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sewage discharge structures, and in particular relates to an intermediate water tank sewage discharge structure. Background Art
[0002] In power plants, there are usually multiple intermediate water tanks to meet the normal water demand of power plants. After multiple cycles, the water in the intermediate water tanks is prone to sludge deposition at the bottom, which needs to be discharged through a sewage pump. When the sludge reaches a certain thickness, it is difficult for the sludge lifting pump to pump water, which can easily lead to the problem of idling of the sludge lifting pump. When the lifting pump cannot pump water, a temporary submersible sewage pump must be connected to a temporary water hose to pump water. The temporary water hose is long and inconvenient to fix. Sometimes leakage will pollute the environment and is inconvenient to operate. Utility Model Content
[0003] Aiming at the technical problem that sludge accumulation affects the operation of sewage pump in the existing intermediate water tank sewage discharge, the utility model provides an intermediate water tank sewage discharge structure, which can reduce the sewage discharge difficulty of the water pump and avoid idling of the water pump.
[0004] The utility model provides a sewage discharge structure of an intermediate water pool, comprising an intermediate water pool, a water diversion pipe, a diversion pipe, a water inlet pipe, a water pump and a water outlet pipe, wherein the water pump is located above the intermediate water pool, one end of the water inlet pipe is located at the bottom of the intermediate water pool, the other end of the water inlet pipe is connected to the water pump, the water outlet pipe is connected to the water pump, the water diversion pipe extends from the outside of the intermediate water pool to the bottom of the intermediate water pool, and the water outlet of the water diversion pipe faces the water inlet of the water inlet pipe, a first valve is arranged on the water diversion pipe, one end of the diversion pipe is connected to the water diversion pipe, the other end of the diversion pipe is connected to the water outlet pipe, and a second valve is arranged on the diversion pipe.
[0005] Furthermore, the first valve and the second valve are electrically controlled valves.
[0006] Furthermore, a filter screen is provided at the water inlet of the water inlet pipe.
[0007] When the sewage discharge structure of the intermediate water tank is performing sewage discharge operation in the intermediate water tank, before the water pump is started, the second valve can be opened in advance, and a certain amount of water can be injected into the water pump in advance to avoid the problem of idling start of the water pump. At the same time, after the water pump is started, the second valve is closed. When the sludge deposition thickness at the bottom of the intermediate water tank is too large, the first valve is opened, and water is injected into the water inlet of the water inlet pipe through the water diversion pipe, so as to dilute the sludge introduced by the water inlet pipe and avoid the problem of difficulty in lifting the water pump due to excessively high sludge concentration. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
