Secondary water supply equipment

Abstract

The invention provides secondary water supply equipment which comprises a water tank. An annular wall water inlet pipe is fixed to the inner wall of a water tank. The upper portion of the water tank is provided with a ventilation pipe and a manhole cover, wherein the pipe orifice of the ventilation pipe is fixedly provided with a filtering net. The lower portion of the water tank is provided with a water outlet pipe. The bottom of the water tank is provided with a sediment deposition pool. An overflow pipe is arranged in the water tank. The pipe orifice of the lower portion of the ventilation pipe is connected with the overflow pipe. The overflow water gap of the overflow pipe is arranged on the lower portion of the ventilation pipe. The overflow water gap is located above the annular wall water inlet pipe. A sediment discharge pipe is arranged on the bottom of the water tank. The pipe orifice of one end of the sediment discharge pipe is arranged in the sediment deposition pool, and the pipe orifice of the other end of the sediment discharge pipe is arranged outside a tank body of the water tank. The overflow pipe is communicated with the sediment discharge pipe through a middle pipeline. According to the secondary water supply equipment, as the sediment discharge pipe is arranged, and the ventilation pipe and the sediment discharge pipe are communicated, even if the pipe orifice filtering net is broken or damaged by people, small animals or thrown noxious substances entering the pipe orifice enter the sediment discharge pipe through the middle pipeline and are discharged out of the water tank. As a dredging device can be started to operate at any time, sediment in the sediment deposition pool can be directly discharged from the sediment discharge pipe after being stirred.

Description

technical field [0001] The invention relates to a secondary water supply device, in particular to a secondary water supply device with energy saving and environmental protection, especially a secondary water supply device that can ensure people's drinking water safety, health and sanitation. Background technique [0002] The secondary water supply device of prior art adopts a casing as majority, and water inlet pipe and outlet pipe are set in casing, and the manhole of a stamping is set on casing top, is convenient to cleaning and overhaul. In addition, overflow pipes and ventilation pipes are also provided. Its shortcomings are mainly that the hygiene and safety cannot be guaranteed, the inside of the box is inconvenient to clean, and the water at the bottom will be stirred when the water enters, which affects the use. Chinese patent 201120041188.6 discloses a "energy-saving, hygienic and safe secondary water supply equipment" ( figure 1 shown) to solve the above-mentione...
