Abstract
The utility model discloses an automatic back-flushing device of an underground water purifier, which has simple structure. The automatic back-flushing device of the underground water purifier comprises a filter vat (2). The automatic back-flushing device of the underground water purifier is characterized in that a communication pipe (3) communicated with a water outlet (8) at the bottom of the filter vat (2) is arranged in the filter vat (2), a pulling rope (4) is installed in the communication pipe (3), one end of the pulling rope (4) is connected with a floater (1) in the filter vat (2), and the other end of the pulling rope (4) is connected with a closing plate (6) sealing the water outlet (8). The utility model has the characteristics of simple structure, good back-flushing effect and the like and is convenient to use.
Description
Technical field
The utility model relates to a kind of purifier, specifically a kind of ground water cleaning device automatic backwash device.
Background technology
Existing ground water cleaning device in use for some time, it is more and harden the sediment of filtrate upper surface of filter often to occur, therefore, requires the ground water cleaning utensil that back purge system is arranged.At present, back purge system general using siphon principle, its volume is big, complex structure, the cost height.And require the water level at backwash initial stage higher, otherwise the clear water in the scuttlebutt can not pass through the filtrate upper surface, back purge system just can not be worked, and can not reach the purpose of flushing filtrate.
Summary of the invention
The purpose of this utility model provides a kind of ground water cleaning device automatic backwash device simple in structure.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of ground water cleaning device automatic backwash device, it comprises filter vat, be provided with the cross over pipe that communicates with filter vat bottom delivery port in the filter vat, pull rope is installed in the cross over pipe, float in pull rope one end and the filter vat is connected, and the other end is connected with the shrouding that seals delivery port.
The utility model can seal delivery port for making shrouding, and shrouding is provided with sealing plate.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, has characteristics such as simple in structure, easy to use, that backwash effect is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of ground water cleaning device automatic backwash device, it comprises filter vat 2, be provided with the cross over pipe 3 that communicates with filter vat 2 bottom delivery ports 8 in the filter vat 2, pull ropes 4 are installed in the cross over pipe 3, and pull rope 4 one ends are connected with float 1 in the filter vat 2, and the other end is connected with the shrouding 6 that seals delivery port 8, for reducing friction, pull rope 4 is installed in the cross over pipe 3 by fixed pulley 9.
The utility model can seal delivery port 8 for making shrouding 6, and shrouding 6 is provided with sealing plate 7.
The utility model is when clarifier energy normal filtration water, and raw water arrives scuttlebutts through water distributor 10 by filtrate 5, gathering ground 11, and the buoyancy that float 1 is subjected to is less than the weight of shrouding 6, and shrouding 6 is with delivery port 8 sealings.More and when hardening when the deposit above the filtrate 5, just only some arrives gathering ground 11 to raw water, water level in the filter vat 2 just rises gradually like this, the buoyancy of float 1 increases gradually, when buoyancy continues to increase after reaching equalization point, float 1 is mentioned shrouding 6 by pull rope 4, and the water in the filter vat 2 discharges from delivery port 8 fast through cross over pipe 3, water distributor 10.During water level in the water level in the scuttlebutt is higher than filter vat 2, clear water just flows to water distributor 10 in the filter vat 2 by clear water pipe, gathering ground 11 by filtrate 5, discharges from delivery port 8, and filtrate 5 is rinsed well, realizes backwash.When the water level in the filter vat 2 was reduced to desired location, the buoyancy of float 1 reduced gradually, and shrouding 6 is under the gravity effect, and with delivery port 8 sealings, backwash stops.So circulation can realize the clarifier automatic backwash.
Claims (2)
1. ground water cleaning device automatic backwash device, it comprises filter vat (2), it is characterized in that being provided with in the filter vat (2) cross over pipe (3) that communicates with filter vat (2) bottom delivery port (8), pull rope (4) is installed in the cross over pipe (3), float (1) in pull rope (4) one ends and the filter vat (2) is connected, and the other end is connected with the shrouding (6) that seals delivery port (8).
2. ground water cleaning device automatic backwash device according to claim 1 is characterized in that shrouding (6) is provided with sealing plate (7).
