Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, specifically to a V-shaped filter tank bidirectional shared tank structure based on water flow switching. Background Technology
[0002] A V-type filter is a water treatment structure used in water plants, referring to a rapid filter that maintains a constant water level. The inlet channels on both sides of the filter are V-shaped. An ultrasonic automatic water level control device inside the filter adjusts the outlet clear water valve, which automatically adjusts its opening degree according to the water level in the filter to maintain a constant water level.
[0003] Typically, V-type filters use a single layer of sand filter media with a particle size of 0.95-1.35 mm, a non-uniformity coefficient of 1.2-1.6, and a filter media layer thickness of 1.0-1.5 m.
[0004] Traditional V-type filters require separate inlet and backwash tanks, resulting in complex tank structures, large footprints, low hydraulic switching efficiency, and valve redundancy. Utility Model Content
[0005] The purpose of this utility model is to provide a bidirectional shared tank structure for a V-shaped filter based on water flow switching, which solves the technical problems of traditional V-shaped filters requiring separate inlet tanks and backwash tanks, resulting in complex tank structure, large footprint, low hydraulic switching efficiency, and redundant valves.
[0006] This utility model discloses a V-shaped filter bidirectional shared tank structure based on water flow switching, including a tank body. The tank body is connected to a rotating diversion device. The rotating diversion device includes a guide wall disposed inside the tank body and a driving device outside the tank body. The driving device is connected to the guide wall and drives the guide wall to achieve vertical and horizontal placement. When the guide wall is placed horizontally, its size is adapted to the opening of the tank body.
[0007] Working principle: During use, when filtration is required, the drive device places the guide wall horizontally to function as the inlet tank. When backwashing is required, the drive device places the guide wall vertically for backwashing. By setting up the guide wall and using it in conjunction with the drive device, one tank can perform the functions of both the inlet tank and the backwash tank. This solves the problems of existing technologies that require separate inlet and backwash tanks, resulting in complex tank structures, large footprints, low hydraulic switching efficiency, and valve redundancy.
[0008] Furthermore, the tank is U-shaped, and multiple inlet and outlet ports are provided on the two U-shaped walls. The inlet and outlet ports drain water during filtration and enter water during backwashing.
[0009] By setting inlet and outlet water inlets, the requirement that the inlet water tank and backwash water tank share a single tank can be met.
[0010] Furthermore, the multiple inlets and outlets are evenly arranged on the U-shaped wall of the tank.
[0011] By evenly distributing multiple inlets and outlets on the U-shaped wall of the tank, the water flow can be uniformly distributed during filtration.
[0012] Furthermore, the drive device is connected to a sensor.
[0013] By installing sensors, the operation of drive devices can be made more automated, reducing the need for manual labor.
[0014] Furthermore, the driving device is a motor.
[0015] By setting the drive device to a motor, the guide wall can be automatically flipped, making the switching between the inlet tank and the backwash tank more automated.
[0016] Furthermore, the motor is also connected to a PLC interlocking control system.
[0017] By connecting the motor to the PLC interlocking control system, mode switching is automated, achieving a higher degree of automation.
[0018] Furthermore, a water inlet gate is provided on one side of the tank.
[0019] By setting an inlet gate, the tank filters the incoming water when the inlet gate is opened, and then discharges it from the inlet and outlet.
[0020] Furthermore, the rotation fulcrum of the flow guide wall is positioned close to the U-shaped wall of the trough.
[0021] Furthermore, the rotation fulcrum of the flow guide wall is located in the middle of the two U-shaped walls of the trough.
[0022] Furthermore, a backwash water outlet is provided at the bottom of the tank.
[0023] By setting up a backwash water outlet, the backwash water can be discharged, ensuring the normal operation of the backwash function.
[0024] Compared with the prior art, the beneficial effects of this utility model are:
[0025] 1. By setting up a flow guide wall and using it in conjunction with a drive device, one tank can realize the functions of two tanks: an inlet tank and a backwash tank. This solves the problem that existing technologies require separate inlet tanks and backwash tanks, resulting in complex tank structures, large footprints, low hydraulic switching efficiency, and valve redundancy.
[0026] 2. By setting inlet and outlet water inlets, the requirement that the inlet water tank and backwash water tank share a single tank can be met;
[0027] 3. By evenly arranging multiple inlets and outlets on the U-shaped wall of the tank, the water flow can be evenly distributed during filtration;
[0028] 4. By setting up sensors, the automation level of the drive unit can be increased, reducing the need for manual labor;
[0029] 5. By setting the drive device to a motor, the guide wall can be automatically flipped, making the switching between the inlet tank and the backwash tank more automated;
[0030] 6. By connecting the motor to the PLC interlocking control system, mode switching is automated, resulting in a higher degree of automation;
[0031] 7. By setting an inlet gate, the tank filters the incoming water when the inlet gate is opened, and the water is discharged from the inlet and outlet.
[0032] 8. By setting up a backwash water outlet, the backwash water can be discharged, ensuring the normal operation of the backwash function. Attached Figure Description
