Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
nullAs shown in Figure 1-2，Gas backwash type defecator of the present utility model includes controller、Tank body 1，In being arranged on tank body and tank inner chamber room is divided into the filter house 2 in muddy water chamber and clear water chamber，Water inlet pipe 10 that is that connect with described muddy water chamber and that be respectively arranged with water intaking valve 5 and blowoff valve 6 on it and blow-off pipe 14，The outlet pipe 7 connected with described clear water chamber，Described outlet pipe 7 and water supply branch road 9 and ventilation branch road 8 also connect，Before being provided with to prevent from carrying out gas backwash on described ventilation branch road, water enters into the check-valves (not shown) in ventilation branch road、Control the intake valve 11 of ventilation break-make and connect with high-pressure air source，It is provided with outlet valve 12 on described water supply branch road，Wherein said intake valve、Water intaking valve、Drain valve、Blowoff valve is electrodynamic valve and controlled with described controller is respectively connected，Simultaneously，The outlet valve fore-end of described ventilation branch road or outlet pipe or water supply branch road is provided with piezometer 13，Utilize piezometer to open supply air pressure and water supply pressure to be measured simultaneously，Ensure that the pressure of backwash and water supply can be surveyed.Wherein, described water supply branch road and left and right two parts that ventilation branch road can be the T-shaped pipe that middle part connects with described drain pipe, or use tee T side-connecting to arrange.
Filter of the present utility model, current enter clear water chamber after being entered muddy water chamber by water inlet pipe after filter house, and final clear water is sent to each terminal of dust suppression system from outlet pipe via water supply branch road and sprayed.When needing to filter, by the feed water valve on water supply branch road, water intaking valve on water inlet pipe simultaneously closes off, and opens the intake valve on ventilation branch road, and now gases at high pressure enter tank interior at drain pipe, constantly carry out supercharging, during to certain pressure, opening blowoff valve, instant water flows out in tank body, take away impurity on drainage screen, and then realize backwash.And, according to venturi principle, steam is sufficiently mixed and can seethe with excitement in screen surface, quickly can be rushed by impurity screening, and discharge from blow-off pipe, complete cleaning.The structure design of gas backwash type filter makes the service efficiency of filtration be greatly improved compared to conventional backwash filter.And decrease water waste.For aerosol dust suppression, source of the gas accesses more convenient.
Specifically, as shown in Figure 2, described filter house 2 includes the connecting cylinder 21 that can be set in described tank body matchingly, it is formed at connecting cylinder one end the adpting flange 22 corresponding with the opening of tank body, is fixedly installed on the plane formula filter screen 23 of the other end of connector drum, the form of drainage screen is set bottom employing, same working environment, good filtration effect, blocking rate is low, and the service life of drainage screen also can improve.
Preferably, described tank body is setting up and down, described tank body upper end is provided with being formed centrally the upper cover plate 15 of apopore, described drain pipe and described upper cover plate are fixing to be connected or is integrally formed, and described upper cover plate is fixed with tank body upper end and is connected and by described adpting flange clamping and positioning and arrange sealing gasket betwixt to ensure sealing.Vertically-mounted filter house also makes filter screen be horizontally disposed with, and effectively prevents impurity from piling up, and when carrying out gas back-flushing, filter screen rinses uniformly everywhere, it is ensured that backwash effect.
As a preferred version, being formed with connection limit described filter screen ring week, described cylinder and filter screen opposite end are formed with internal ring limit, and the described limit that connects is connected with described internal ring limit bolt, is bolted the convertibility that can improve filter screen, reduces use cost.
As a specific embodiment, described filter screen is made up of the supporting network of upper screen and lower screen and centre, described supporting network is spoke type or latticed, and it has bigger hole and with intensity to strengthen filter screen bulk strength, simultaneously, described lower screen and upper screen are thin mesh grid, such as 150 mesh or 200 mesh etc., it is preferable that upper screen and lower screen use the mode filtered step by step to arrange, while improving filter effect, reduce blocking and occur.
Specifically, described tank body lower end is formed with tapered portion, described tapered portion and described blow-off pipe Flange joint.Meanwhile, drain pipe and ventilation branch road, the connection between water supply branch road, or T-shaped pipe, the connection of each valve all use Flange joint, easy to maintenance, mounting or dismounting simple, in real work, reduces the incidence rate of the problem affecting work efficiency.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
