Abstract
The utility model discloses a backwashing device of a groundwater purifier with a simple structure, which comprises a filter barrel (2) and is characterized in that a connection tube (3) is arranged outside the filter barrel (2); one end of the connection tube (3) is communicated with a water outlet (8) at the bottom of the filter barrel (2), and the other end of the connection tube (3) is communicated with a water tank (1); a traction rope (4) is arranged in the connection tube (3); one end of the traction rope (4) is connected with the water tank (1), and the other end of the traction rope (4) is connected with a sealing plate (6) for sealing the water outlet (8); and a water outlet valve (12) is arranged at the bottom of the water tank (1). The backwashing device disclosed by the utility model has the characteristics of simple structure and good backwashing effect, is convenient to use and the like.
Description
Technical field
The utility model relates to a kind of purifier, specifically a kind of ground water cleaning device back purge system.
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 back purge system 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 back purge system, it comprises filter vat, filter vat is provided with cross over pipe outward, and cross over pipe one end communicates with the delivery port of filter vat bottom, and the other end communicates with water tank, pull rope is installed in the cross over pipe, pull rope one end is connected with water tank, and the other end is connected with the shrouding of sealing delivery port, and water tank bottom is provided with outlet valve.
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 back purge system, it comprises filter vat 2, the filter vat 2 outer cross over pipes 3 that are provided with, cross over pipe 3 one ends communicate with the delivery port 8 of filter vat 2 bottoms, the other end communicates with water tank 1, and pull rope 4 is installed in the cross over pipe 3, and pull rope 4 one ends are connected with water tank 1, the other end is connected with the shrouding 6 of sealing delivery port 8, water tank 1 bottom is provided with outlet valve 12, and 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.Because the weight of water tank 1 is less than the weight of shrouding 6, 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, simultaneously, the water level of the cross over pipe 3 of Lian Tonging also rises gradually with it, in flowing into water tank 1, because the water yield of the outlet valve 12 on the water tank 1 is less than the inflow by cross over pipe 3, water in the water tank 1 is more and more, when the water yield continued to increase after reaching equalization point, at this moment, the weight of water tank 1 was greater than the weight of shrouding 6, by pull rope 4 shrouding 6 is mentioned, the water in the filter vat 2 is through cross over pipe 3, water distributor 10 discharges fast from delivery port 8.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 in the water tank 1 after outlet valve 12 is discharged a period of times, the weight of water tank 1 is less than the weight of shrouding 6, shrouding 6 is under the gravity effect, with delivery port 8 sealings, backwash stops.So circulation can realize the clarifier automatic backwash.
Claims (2)
1. ground water cleaning device back purge system, it comprises filter vat (2), it is characterized in that the outer cross over pipe (3) that is provided with of filter vat (2), cross over pipe (3) one ends communicate with the delivery port (8) of filter vat (2) bottom, the other end communicates with water tank (1), and pull rope (4) is installed in the cross over pipe (3), and pull rope (4) one ends are connected with water tank (1), the other end is connected with the shrouding (6) of sealing delivery port (8), and water tank (1) bottom is provided with outlet valve (12).
2. ground water cleaning device back purge system according to claim 1 is characterized in that shrouding (6) is provided with sealing plate (7).
