Specific implementation mode
The present invention is converted into air-flow using backwash bubble in explosion, by bubble collecting device the gas in bubble
Collect to form continuous air-flow, backwashes situation by detecting the i.e. detectable detection faces of stream condition, then move and fill by slide unit
It sets and drives bubble trap movement, you can detect the backwashing state in entire filter tank 2.It can be obtained eventually by MICROCOMPUTER PROCESSING whole
The cleaning situation in a filter tank 2.
Filter tank 2 backwashes the operation principle of tester：Filter tank 2 reaches the water surface in backwash, by the upward bubble of bottom of pond
After rupture, the gas in bubble is collected by bubble trap, bubble trap gas collection end place under water, multiple bubbles exist
Air-flow is will produce when being ruptured in collector, is flowed along pipeline by hydraulic pressure gas, air flow state is detected by sensing chamber,
To know that the backwash rate and flushing effect of current region, bubble trap are combined by multiple collection chambers, energy
The flushing effect of single-point, multiple spot is surveyed simultaneously.
Filter tank 2 as shown in Figure 1 backwashes tester and is fixed on the holder of 2 top of filter tank, and the side of line scanning may be used
Multiple air collecting chambers 10 are arranged side by side in formula, the quantity of air collecting chamber 10 is depending on 2 width of filter tank, air collecting chamber 10 arranged side by side
Width be slightly less than the width in filter tank 2 and avoid interfering with pool wall when scanning along filter tank 2.Tester is equipped with collection from bottom to top
Air cavity 10, tracheae 8, flow velocity test mouth 7, and each air collecting chamber 10 tests mouth 7, a set of air collecting chamber equipped with independent tracheae 8 and flow velocity
10, tracheae 8, flow velocity test mouth 7 constitute pipeline configuration up and down, in order to ensure that measurement efficiency, the internal diameter of tracheae 8 are less than collection
The internal diameter that air cavity 10, flow velocity test mouth 7 is less than tracheae 8, can improve and collect the impact force that bubble constitutes air-flow.Air collecting chamber 10
By 9 connectivity trachea 8 of gas outlet, gas outlet 9 is from air collecting chamber 10 to the gradually smaller structure of 8 bore of tracheae, Ke Yiyou for top
Help improve the flow velocity of collected gas.
Flow detector 6 there are one being all provided in each flow velocity test mouth 7, and flow velocity test mouth 7 is equipped with and receives air collecting chamber 10
The gas outlet 9 of the gas discharge of collection, flow detector 6 are a device obtained through current rate/dynamics/pressure, such as
Mechanism as shown in Figure 3 may be used, it is horizontally disposed tubular structure that flow velocity, which tests mouth 7, and flow detector 6 includes 11 He of fin
Strain gauge 12, fin 11 are fixed on above the inner wall of flow velocity test mouth 7 and extend straight down, 11 bottom of fin and flow velocity
Test mouth 7 inner wall bottom does not contact, and with the gap bent for fin 11, fin 11 be vertically arranged can avoid fin 11 because
Its own gravity and bend, reduce conversion difficulty, strain gauge 12 is fixed on fin 11, and strain gauge 12 incudes wing
The curvature of piece 11, when air-flow is big, 11 curvature of fin is big, and when air-flow is small, 11 curvature of fin is small, strain gauge 12
Export 11 deformation parameter value processor of fin.
The parameter of acquisition is delivered to processor by each flow detector 6, then is constituted to different zones on a line
Backwashing parameters are acquired, when filter tank 2, which backwashes tester, is moved along filter tank 2, you can the flushing for testing entire pond is equal
The backwash rate of even property and each position.The data of acquisition are stored and/or are delivered to display screen and shown by processor.
Backwash tester based on filter tank 2, can be devised by filter tank 2 and backwash test system, system include holder with
And filter tank 2 backwashes tester.As shown in Fig. 2, branch is provided with the bilateral meter step track 3 for being fixed on 2 both sides of filter tank, truss cunning group
1 is supported on positioned at 2 top of filter tank and by counting step wheel 4 on bilateral meter step track 3, and meter step wheel 4 can accurately walk, and obtain
Filter tank 2 backwashes position (coordinate) information of tester.The power unit of 4 rotation of driving meter step wheel is fixed in truss cunning group 1,
The gear-box of connection stepper motor may be used in power unit, and filter tank 2 backwashes tester and is suspended in 1 lower section of truss cunning group.
Sounding gear is housed in bubble trap side, entire pond can be done under the drive of slide unit after the completion of flushing sweeps
It retouches, filtrate tiling uniformity is may know that under MICROCOMPUTER PROCESSING, while being scanned before flushing with sounding gear with after flushing
It obtains rinsing front and back difference in height, the expansion rate of filtrate is can be obtained by numerical computations.Expansion rate=(height-punching after flushing
Wash preceding height)/rinse preceding height * %.
Sonar set can be used in sounding gear, and sonar set is fixed along air collecting chamber 10, using 1 lower zone of truss cunning group
Filtrate spacing, when sonar set works, by range data of the acquisition apart from filtrate to processor, processor while output driving
Signal coordinates entire filter tank 2 and backwashes the work of test system to elevating mechanism 5 and power unit.
In order to avoid filter tank 2 backwashes the normal work in test systematic influence filter tank 2, it is fixed in truss cunning group 1 vertical
The elevating mechanism 5 of direction movement, filter tank 2 backwash tester and are fixed on the elevating mechanism 5 of truss cunning group 1, can be in filter tank 2
It when normal work, rises filter tank 2 and backwashes tester, be both avoided that filter tank 2 backwashed tester and influences its work, and be also avoided that
Sewage backwashes tester to filter tank 2 and causes to corrode.
The test method of test system is backwashed based on above-mentioned filter tank 2：
Original state, meter step 4 sub-truss cunning groups 1 of wheel are located at 2 one end of filter tank, and elevating mechanism 5 is in propradation, sound
Equipment and air collecting chamber 10 are located at the top of 2 liquid level of filter tank；
Before backwash, elevating mechanism 5 declines, and sonar set and air collecting chamber 10 are placed in the lower section of 2 liquid level of filter tank, driving meter
Step wheel 4 makes 1 conduct of truss cunning group to 2 other end of filter tank along the step walking of track 3 of bilateral meter, counts 4 walking of step wheel while starting sonar
The filtrate elevation information of acquisition is delivered to processor by equipment；
Start backwash, driving meter step wheel 4 keeps 1 conduct of truss cunning group initial to filter tank 2 along the step walking of track 3 of bilateral meter
End, the flow rate information of acquisition is delivered to processor to 4 walking of meter step wheel by flow detector 6 simultaneously；
After backwash, driving meter step wheel 4 keeps 1 conduct of truss cunning group another to filter tank 2 along the step walking of track 3 of bilateral meter
End, meter step wheel 4 walk while starting sonar set, and the filtrate elevation information of acquisition is delivered to processor again；
Finally, elevating mechanism 5 rises, and sonar set and air collecting chamber 10 are promoted to the top of 2 liquid level of filter tank.
