Abstract
The utility model provides a back flushing device of a water supply filter, belongs to the technical field of underground mist spray dedusting and aims to solve the technical problems of poor dedusting and time and energy waste for cleaning due to a blocked nozzle which is caused by a great quantity of large impurities in the supply water of an underground mist spray dedusting device. The device is characterized in that a parallel branch (2) is additionally assembled between the input end and the output end of a filter (7), and a bypass valve (1) is arranged on the branch; a drainage pipeline is arranged between the connection part of the parallel branch on the input end of the filter and the output end of the filter, and a drain valve (4) is installed on the drainage pipeline; a cleaning valve (3) is arranged between a tee (5) of the drainage pipeline and the connection part of the parallel branch; and a main valve (8) is installed between the connection part of the parallel branch on the output end of the filter and a nozzle. By utilizing the device, a blocked filter screen is easy and quick to clean, so that time and labor are saved.
Description
Technical field
The utility model belongs to down-hole spray for dust suppression technical field, is specifically related to feed water filter back flush device.
Background technology
At present, the down-hole spray dust remover is, larger obstruction nozzle more because of impurity in supplying water often, causes dedusting ineffective, and working environment is worsened, and affects workers ' health, when this device is changed, wastes time and energy.
Summary of the invention
The purpose of this utility model is to solve the problem that prior art exists, and feed water filter back flush device is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
Feed water filter back flush device is characterized in that: install bypass in parallel additional between the input of filter and output, this bypass arranges bypass valve; Between bypass access place in parallel of filter input and filter input, the pipeline that discharges water is set, this pipeline that discharges water is equipped with discharging valve; Be provided with cleaning valve between discharge water pipeline threeway and bypass access place in parallel; After bypass access place in parallel of filter output, main valve is installed.
The present invention compared with prior art has following beneficial effect:
Because the utility model adopts back purge system, make flushing filtering net stop up the simple and fast that becomes, effect is remarkable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-bypass valve; 2-bypass in parallel; 3-cleaning valve; 4-discharging valve; 5-the pipeline threeway discharges water; The 6-filter screen; The 7-filter; The 8-main valve.
The specific embodiment
As shown in Figure 1, feed water filter back flush device installs bypass 2 in parallel additional between the input of filter 7 and output, and this bypass arranges bypass valve 1; Between bypass access place in parallel of filter input and filter input, the pipeline that discharges water is set, this pipeline that discharges water is equipped with discharging valve 4; Be provided with cleaning valve 3 between discharge water pipeline threeway 5 and bypass access place in parallel; Between bypass access place in parallel of filter output and nozzle, main valve 8 is installed.
The course of work and principle:
During the utility model work, during normal operation, first open cleaning valve 3 and main valve 8, close bypass valve 1 and discharging valve 4; Opposite during flushing, namely close cleaning valve 3 and main valve 8, open bypass valve 1 and discharging valve 4, this moment, current were entered by the output of filter, through filter screen 6, were flowed out by input, after the back flush filter screen, impurity were discharged through discharging valve.
