Detailed Description
The following further describes embodiments of the present invention in order to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to the right thereof.
Referring to fig. 1-3, a shallow sand bypass filter comprises a first filter tank 14 and a second filter tank 15 which are arranged side by side, wherein an exhaust pipe 1 is arranged at the center of the top of the first filter tank and the second filter tank, an emptying valve 9 capable of emptying accumulated water in the tank body is arranged at the center of the bottom of the first filter tank and the second filter tank, a drain pipe 7 is arranged at the emptying valve, and the exhaust pipe 1 extends to the bottom from the outer side walls of the first filter tank and the second filter tank and is connected with the drain pipe 7;
a water inlet pipe 4 and a water outlet pipe 6 are arranged on the outer sides of the first filter tank and the second filter tank, the water inlet pipe is connected with a water inlet branch pipe 2 and a sewage discharge pipe 3 through a three-way joint, and the water inlet branch pipe extends to the centers of the upper parts in the first filter tank and the second filter tank; the water outlet pipe 6 is communicated with the first filtering tank and the second filtering tank through a water outlet branch pipe 12, one end of the water outlet pipe is provided with a water outlet, a bypass branch pipe 16 is arranged on the water outlet pipe close to one end of the water outlet, and two ends of the bypass branch pipe are communicated with the water outlet pipe.
One end of the drain pipe is provided with a vent 8.
And a water inlet valve 11 is arranged between the water inlet branch pipe and the water inlet pipe.
A drain valve 10 is arranged between the water inlet pipe and the drain pipe.
And the water outlet branch pipe is provided with a water outlet valve 13.
And a main valve 5 is arranged at one end of the water outlet pipeline, which is close to the water outlet.
And manhole devices 17 are further arranged on the outer side walls of the first filtering tank and the second filtering tank.
Exhaust valves are installed on exhaust pipes at the tops of the first filtering tank and the second filtering tank, the exhaust valves can exhaust air to avoid the phenomenon that the operation of equipment is affected due to the fact that the air pressure in the tanks is too large, and accumulated water in the filtering tanks can be drained by opening a bottom emptying valve so as to be convenient to overhaul and maintain.
