Abstract
The utility model relates to a backflushing monitoring device for a filter tank for a grainy filtering material backflushing system in the processing of water supply and sewage, which is composed of a pressure transducer 1, a pressure transducer 2, a flow transducer 3, a regulating valve 4, a center regulating device 5, a display screen 6, a filter tank 7, a backflushing water outlet 8, a backwashing pump 9 and a backwashing water inlet 10. In the utility model, the technical parameters of backwashing each time through a meter are adopted, and a best backwashing intensity value is found out. Thorough backwashing is carried out to the filter tank by means of a manual or automatic mode, and the normal operation of the filter tank is assured. The utility model is characterized in high automation level, accuracy, convenient supervision and management, reliable use, labor intensity reduction, etc. The utility model is very suitable for being used on the spot.
Description
The utility model relates to a kind of filtering tank backwash watch-dog that is used for the backwashing system of feedwater and sewage disposal particulate filter (quartz sand, diamond dust, active carbon, manganese sand etc.).
The filtering tank of Shi Yonging is filtered into down usually to stream now, be that water is walked from top to bottom, it during backwash upward flow, be that water is walked from the bottom up, before the determining of backwash intensity size put into serial production by filtering tank, manual measure during the test run, this measurement result as filter tank life's work backwash intensity level.Because the backwash intensity in each cycle of filter tank is too big filtrate is washed away; The too little filtrate of perhaps backwash intensity can not dash, and does not reach the backwash effect, influences the effluent quality of next filter cycle, and severe patient causes filter tank to be filtered the hydraulic pressure accident of collapsing.
The purpose of this utility model is to provide a kind of filtering tank backwash watch-dog, be directed to the deficiency that existing backwash mode exists, detect the technical parameter of each backwash by instrument, therefrom find out best backwash intensity level, by manual or automated manner filter tank is carried out backwash more completely, guarantee the filter tank operate as normal.
The purpose of this utility model is achieved in that it is made up of pressure transmitter (1), pressure transmitter (2), flow transmitter (3), control valve (4), centering magnet (5), display screen (6), filter tank (7), backwash delivery port (8), backwashing pump (9), backwash water inlet (10).The pressure transmitter (1) that filter tank (7) is drawn, pressure transmitter (2) are connected with centering magnet (5) respectively; Filter tank (7) top connects backwash delivery port (8), and the bottom is connected to control valve (4), backwashing pump (9), backwash water inlet (10); Centering magnet (5) is connected with display screen (6), flow transmitter (3) respectively, and the other end of flow transmitter (3) is connected on the back with water inlet line.
When carrying out backsurging operation, fluid enters the filter tank (7) through backwashing pump (9), control valve (4) from backwash water inlet (10), wash filtering layer in filter tank (7) lining, and flow out from the backwash delivery port (8) on filter tank (7) top, data on the pressure transmitter (1) of centering magnet (5) by being attached thereto, pressure transmitter (2), the flow transmitter (3), calculate, analyze, judge, find out best backwash intensity, and show at display screen (6), control and regulation valves (4) are adjusted flow intensity.
The utility model is owing to adopted the structure that is connected with pressure transmitter (1), pressure transmitter (2), flow transmitter (3), control valve (4), centering magnet (5), display screen (6) on filter tank (7), detect the technical parameter of each backwash by instrument, therefrom find out best backwash intensity level, by manual or automated manner filter tank is carried out backwash more completely, guarantee the filter tank operate as normal.Have convenience, automatization level height, accurately, be convenient to supervision and management, characteristics such as reliably use, reduce labor intensity, be well suited for The field.
Fig. 1 is the utility model automatic control structure schematic diagram.
Fig. 2 is the manual control structure schematic diagram of the utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
The purpose of this utility model can be passed through manual or automatic dual mode and realize,
Embodiment 1: self-action, it comprises pressure transmitter 1, pressure transmitter 2, flow transmitter 3, control valve 4, centering magnet 5, display screen 6, filter tank 7, backwash delivery port 8, backwashing pump 9, backwash water inlet 10.The pressure transmitter 1 that filter tank 7 is drawn, pressure transmitter 2 are connected with centering magnet 5 respectively; Filter tank 7 tops connect backwash delivery port 8, and the bottom is connected to control valve 4, backwashing pump 9, backwash water inlet 10; Centering magnet 5 is connected with display screen 6, flow transmitter 3 respectively, and the other end of flow transmitter 3 is connected on the back with water inlet line; Control valve 4 is automatic regulating valves, and centering magnet 5 effects are connected on the control valve 4, realize regulating automatically the purpose of backwash intensity.
Embodiment 2: hand, and basic identical with last example, just control valve 4 is manual modulation valves, centering magnet 5 does not act directly on the control valve 4, reaches the purpose of manual adjustments backwash intensity.
During backwash, show backwash intensity q and loss of flood peak h relation and best backwash intensity, backwash zero hour, the backwash termination moment, backwash time, backwash terminal point sound and light alarm on the display screen 6.
Filtrate has just begun fluidised irrigation flow rate (backwash rate), is called the minimum fluidized voidage flow velocity.Filtering layer begins the starting point of fluidization filtering layer expansion just.During backwash, make the coarse media of low layer just begin to expand, then designing back washing strength should be foundation with the minimum fluidized voidage flow velocity of coarse media just.Consider other influence factor, the design backwash rate can be determined by following formula:
Q=10kv
MfQ: design back washing strength L/S.m2
v
Mf: the minimum fluidized voidage irrigation flow rate of the largest particles filtrate
cm/s
K: safety coefficient k=1.1-1.3
By China used filtrate specification k=1.3
