Air circulation device in secondary water supply stainless steel water tank

Abstract

The invention belongs to the technical field of secondary water supply, and discloses an air circulation device in a secondary water supply stainless steel water tank, which comprises a water tank, the left and right sides of the top of the water tank are fixedly connected with an exhaust pipe and an air inlet pipe respectively, the exhaust pipe is located on the left side of the air inlet pipe, and the outer wall of the lower side of the exhaust pipe is fixedly connected with a liquid inlet pipe; a liquid discharge pipe is fixedly connected to the outer wall of the left side of the water tank, an exhaust assembly is arranged on the exhaust pipe and located on the right side of the liquid inlet pipe, the exhaust assembly comprises a shell connected with the exhaust pipe, two fan blades located in the shell and symmetrically arranged and a driving assembly in transmission connection with the fan blades, and a reinforcing assembly is detachably installed on the upper side of the exhaust assembly. During water supply, water flow drives the two fan blades to rotate, the two fan blades drive the torsional spring to store energy through the transmission assembly, after water supply is stopped, the torsional spring for storing energy drives the fan blades to rotate through the transmission assembly, negative pressure is formed in the shell, and air flow in the water tank is exhausted outdoors through the exhaust pipe.

Description

technical field [0001] The present application relates to the technical field of secondary water supply, and more specifically, relates to an air circulation device in a stainless steel water tank for secondary water supply. Background technique [0002] At present, in urban domestic water pump rooms, in addition to the water supply method without negative pressure equipment, most of them use the secondary water supply method of stainless steel water tanks. In the tap water production process, in order to ensure the sterilization effect, the tap water company often adopts the mode of adding chlorine before leaving the factory. After the tap water enters the secondary water supply tank, residual chlorine will volatilize. Existing secondary water supply tanks only have one or two smaller passive air vents, while larger manholes are usually closed for security reasons. The density of chlorine gas volatilized in tap water is higher than that of air, so it is difficult to disch...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the density of chlorine gas volatilized in the tap water in the water tank is higher than that of the air, and it is difficult to discharge the chlorine gas only by the air holes opened on the water tank for natural ventilation, this application provides a secondary water supply air circulation in the stainless steel water tank device
