Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an emergency regulating tank. Background Technology

[0002] As the name suggests, a wastewater equalization tank is used to regulate the quality and quantity of incoming wastewater. Equalization tanks are typically designed for a retention time of 8-12 hours. Emergency tanks are used in wastewater treatment plants when malfunctions in internal structures or equipment cause effluent to fail to meet standards. This allows the plant sufficient time to resolve the issue, and emergency tanks are typically designed for a retention time of 8-12 hours. Both equalization and emergency tanks require stirring devices to balance water quality and prevent sedimentation at the bottom. In conventional designs, both tanks have inlets and electric valves for switching the inlet. Both tanks require pump sets to lift the wastewater stored within. However, in daily use, the electric valves in emergency tanks are prone to damage due to prolonged disuse. Furthermore, emergency tanks are often empty, leaving the internal stirrers and lift pumps idle for extended periods, increasing initial investment and increasing the failure rate of equipment idle for longer periods. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an emergency regulating tank. By setting up a shared distribution well, switching tank, and outlet tank, the mixing equipment, booster pump, etc., can be shared without affecting normal use, thereby reducing initial investment and lowering equipment failure rate.

[0004] The technical solution adopted in this utility model is: An emergency regulating pool includes a rectangular pool body and a controller. A partition wall is provided in the middle of the rectangular pool body along its width direction. One side of the partition wall is connected to the side wall of the water inlet side of the rectangular pool body, and the other side is connected to the side wall of the water outlet side. The rectangular pool body is divided into a regulating pool and an emergency pool by the partition wall. A distribution well is provided at the top of the intermediate partition wall, and the distribution well is connected to the inlet pipe. A switching pool is provided in the middle of the intermediate partition wall, and an outlet pool is provided on the outlet side. Distribution gates are provided on the side of the distribution well that contacts the regulating pool and the emergency pool, respectively. The switching pool is equipped with a manual gate valve on one side corresponding to the regulating pool and the emergency pool; the outlet pool is equipped with two outlet pumps, and outlet gate valves are installed on the walls of the outlet pool and the adjacent regulating pool and emergency pool respectively; an overflow pipe is installed on the upper side wall of the outlet pool. The controller is electrically connected to the distribution gate, the outlet pump, and the outlet gate.

[0005] Preferably, in the emergency regulating pool, two adjacent guide rods are provided in the switching pool, and an agitator is provided on the guide rod closer to the regulating pool, the agitator being electrically connected to a controller.

[0006] Preferably, in the emergency regulating pool, a first check valve, a telescoping valve, and a second check valve are sequentially installed on the outlet pipe of the water pump, and the end of the outlet pipe away from the water pump is connected to the main outlet pipe.

[0012] Advantages of this utility model: (1) The emergency regulating pool of this utility model is equipped with a distribution well, and a manual and electric dual-purpose gate with low cost and low failure rate is installed inside as the distribution gate, which replaces the usually installed electric valve and saves the initial investment cost. By setting up the distribution well, the incoming water can be distributed to the regulating pool or emergency pool as needed by opening and closing the distribution gate, avoiding the use of expensive electric valves.

[0013] (2) The emergency regulating pool of this utility model, by setting a switching pool, can close the left side gate and open the right side gate when the emergency pool needs to drain water, and load the agitator onto the right guide rod for use in the emergency pool, thus saving the cost of the agitator conventionally configured in the emergency pool and thus saving the project cost.

[0014] (3) The emergency regulating pool of this utility model is equipped with an outlet pool and an outlet gate.
