Abstract
The utility model relates to the improvement of a filter with lightweight filtering material, which is particularly capable of realizing automatic operation. The key point of the utility model is that the bottom of a filter chamber of the filter is provided with a siphon sewage expelling pipe which is provided with a siphon destructive pipe, and the upper part of the filter chamber is provided with a backwashing overflow pipe. The utility model can realize automatic control on stopping sewage expelling, prevent the filtering material from being lost during the siphon sewage expelling, and notice and control water distribution for backwashing.
Description
Utility model is about the improvement to the light filter material filter, relates in particular to a kind of sewage backwash that can effectively stop and causes the wander away filter of filtrate of siphon.
Form the filter of filtering layer by lightweight (proportion＜treat drainage) filtrate (as expanded polystyrene (EPS)), when carrying out the filtrate recoil and clean blowdown, the suspension filtering layer with in the blowdown decline process very easily because of the blowdown siphon filtrate of wandering away takes place, cause the filtrate loss.Siphon takes place when effectively stoping blowdown, and people observe blowdown water level decline situation by being installed on the filter transparent visor, reduce to a certain position when blowdown, in time close blowoff valve, reaches to stop the blowdown siphon to prevent to run the mistake filtrate.Yet thisly observing the control siphon by transparent visor and take place, very easily cause carelessness or control improperly, is not to close blowoff valve in advance, causes blowdown not thorough; Lag exactly and close blowoff valve, cause the part filtrate to efflux loss.When filtrate recoil was cleaned, rising water stage control also was to observe transparent visor in addition, closing the recoil water inlet, equally also had above-mentioned defective, excessive recoil water waste water resource, and it is not thorough to cross flushing at least, needs repeatedly flushing, same waste water resource.
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of and can stop siphon that the filter that loses filtrate takes place to run effectively automatically when filtrate being recoiled the cleaning blowdown.
Another purpose of utility model also is to provide the filter of automatic bulletin of a kind of energy or control backwash water inlet spill-over.
The utility model main purpose realizes that it mainly improves and is one siphon blow-off pipe to be set and siphon destructing tube (mouth) is set in filter filter chamber bottom on the siphon blow-off pipe.Specifically, utility model comprises that the filtrate dividing plate is separated into the cartridge filter of bottom filter chamber and top clean water chamber, the light filter material that suspension is arranged in the said filter chamber is characterized in that the siphon blow-off pipe is arranged at said filter chamber bottom, and said siphon blow-off pipe is provided with siphon destructing tube (mouth).Like this when the back blowdown is cleaned in recoil to filtrate, by the gravity blowdown, then change the siphon blowdown over to, earlier when liquid level is reduced to siphon destructive mouth lower end, air in the filter just enters the siphon blow-off pipe by the siphon destructive mouth, need not keep an eye on automatic prevention siphon generation thereby reach.
The said siphon blow-off pipe of utility model is meant the comb that can form siphon, and it is made up of the siphon tedge and the siphon down-comer that are communicated with, and the simplest is inverted-loop tube.Said filter chamber bottom is provided with the siphon blow-off pipe, is meant that the suction inlet of siphon blow-off pipe places the filter chamber bottom, helps the discharge of bottom mud like this.The effect of siphon blow-off pipe and siphon destructing tube (mouth) is: can thoroughly get rid of the mud of filter bottom, again can be by regulating the height of siphon destructive mouth, and control filtering layer falling head prevents that misoperation from causing the filtrate siphon to discharge.
For effectively controlling the backwashing water lifting height, prevent the spill-over waste water resource, can overflow pipe be set at filter filter chamber filtrate dividing plate downside, to show or control recoil water inlet.
Description below in conjunction with two non-limiting embodiment further specifies utility model.
Fig. 1 is embodiment 1 structural representation.
Fig. 2 is embodiment 2 structural representations.
Embodiment 1: filter simplified 2 and be separated into top clean water chamber 6 by filtrate dividing plate 5, filter chamber, bottom 3 is placed with a certain amount of light filter material 4 in the filter chamber.Filter bottom is circumscribed with inverted U-shaped siphon blow-off pipe 14, be respectively equipped with water intaking valve 11 and blowoff valve 12 (also water inlet pipe and blow-off pipe can be separated) on it, there is flocculation water-distributing device 1 the water inlet rear end, the filter chamber bottom has a siphon destructing tube 13 to be communicated with filter chamber and siphon blow-off pipe, filter chamber upper baffle plate downside is provided with band valve backwash water level overflow pipe 10, and the clean water chamber upper top has outlet pipe 9 and breather pipe 7 and valve 8.
During to the filtrate backwash, open blowoff valve 12, filtrate descends with blowdown, when water level is reduced to siphon destructing tube 13 times, air enters siphon blow-off pipe 14 through breather valve 8, breather pipe 7, siphon destructing tube 13, destroy siphon and stop blowdown automatically, prevented that filtrate from discharging with the blowdown siphon because of manually-operated control is improper.When backwash water distribution water level rises to overflow pipe 10, the overflow pipe water outlet shows that the full or control of bulletin backwashing water closes the backwash water inlet.
Embodiment 2: referring to Fig. 2 such as embodiment 1, inverted U-shaped siphon blow-off pipe 14 places in the filter chamber 3, on the siphon tedge of siphon blow-off pipe siphon destructive mouth 13 is arranged, and tubaeform suction mud mouth 15 is arranged at the bottom.
Utility model is owing to be provided with the siphon blow-off pipe and siphon destructing tube is set on blow-off pipe in filter chamber bottom, thereby can control automatically and stop blowdown, avoids causing because of manually-operated control is improper the blowdown siphon filtrate of wandering away.The overflow pipe on filter chamber top shows or control recoils, and water distribution is extremely suitable, avoids the improper waste water resource of manual operation.Adopt said structure, can realize that filter operates automatically, the control of the economy can be used for various light filter material filters.
Claims (4)
1, a kind of siphon drain filter, comprise that the filtrate dividing plate is separated into the cartridge filter of filter chamber top, bottom clean water chamber, the light filter material that suspension is arranged in the said filter chamber is characterized in that the siphon blow-off pipe is arranged at said filter chamber bottom, and said siphon blow-off pipe is provided with siphon destructing tube (mouth).
2,, it is characterized in that said siphon blow-off pipe is located in the filter chamber according to the described siphon drain filter of claim 1.
3,, it is characterized in that said siphon blow-off pipe inlet has tubaeform suction mud mouth according to the described siphon drain filter of claim 2.
