Abstract
The utility model discloses an improved circulating-water bypass-filter back-flushing device, which comprises a circulating-water pump, wherein the circulating-water pump is communicated with a circulating-water pool, a bypass valve is connected with a user water-supply pipe of the circulating-water pump, the water outlet end of the bypass valve is connected with a filter, and the water outlet end of the filter is connected with a back-flushing sewage-discharging pool. The improved circulating-water bypass-filter back-flushing device can perform the same effect under the condition of no use of a back-flushing pump, electrical energy is saved, the flow quantity and the pressure of back flushing are controlled by regulating the opening of the bypass valve, and a back-flushing system is stable and reliable.
Description
Technical field
The utility model relates to the other filter device of a kind of industrial recirculated water, the other filter back purge system of particularly improved recirculated water.
Background technology
The other filter of the used circulation of coking subsidiary factory of ironmaking company is that the turbidity index according to recirculated water carries out backwash to other filter, its backwash is to carry out backwash by unlatching backwashing pump, controlled pressure, backwashing pump opens and closes frequent like this, cause its working life to shorten, it is convenient inadequately to use.
Summary of the invention
The purpose of this utility model is to provide a kind of improved recirculated water other filter back purge system, and it is simple in structure, can realize the backwash effect to other filter under the condition of not opening backwashing pump, and is easy to use.
The purpose of this utility model is to realize like this, the other filter back purge system of a kind of improved recirculated water, comprise the water circulating pump that is connected with circulating water pool, on user's feed pipe of water circulating pump, connecting a bypass valve, the water side of bypass valve is connecting filter, and the water side of filter is connecting the sewage backwash pond.
When the utility model uses, realize backwash, can close water circulating pump, open bypass valve filter, aperture by the control bypass valve, control the flow and the pressure of backwashing water, can under condition, play same backwash effect without backwashing pump, not only simple in structure, save electric energy, and backwashing system is reliable and stable, prolongs the service life of water circulating pump, and is easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a syndeton schematic diagram of the present utility model.
The specific embodiment
The other filter back purge system of a kind of improved recirculated water, as shown in Figure 1, comprise the water circulating pump 2 that is connected with circulating water pool 1, on user's feed pipe 3 of water circulating pump 2, connecting a bypass valve 4, the water side of bypass valve 4 is connecting filter 5, and the water side of filter 5 is connecting sewage backwash pond 6.The utility model can play same backwash effect under the condition without backwashing pump, save electric energy, prolongs the working life of water circulating pump 2.By regulating the aperture of bypass valve 4, control the flow and the pressure of backwashing water in user's feed pipe 3, play backwash effect to filter 5, backwashing system is reliable and stable, and is easy to use.
