Abstract

A differential-pressure swirl-type backwashing filtration system. An indexing mechanism and a transmission mechanism are disposed on the top of a filter cylinder body; the internal cylinder body is divided into a water-inlet chamber and a water-outlet chamber by a clapboard; eight filter cores are disposed in the water-outlet chamber and are distributed uniformly and circumferentially; a water inlet is disposed along a tangent of the cylinder wall of the water-outlet chamber; a sewage draining exit and a dirt discharging exit are disposed in the water-inlet chamber; a sucking disc is disposed between the dirt discharging exit and the clapboard, and is driven to rotate by a transmission shaft of the transmission mechanism. The device adopts eight groups of filter core structures, and by using the hydrodynamics principle, the device has the advantages of less no-load pressure loss, less backwashing water consumption, good filtering effect, compact structure, and reliable operation, and can perform backwashing under low differential pressure.

Description

Pressure reduction, spiral-flow type backwash filter system
Technical field:
The present invention relates to a kind of sewage disposal device, particularly a kind of pressure reduction, spiral-flow type backwash filter system.
Background technology:
The water that has impurity is needed to adopt filter to filter before being sent to water system.Filter commonly used at present is for to be installed with filter in the tank body that has water inlet pipe and outlet pipe.Enter in the filtration tank body when introduce the water that enters by water inlet pipe, after filtering through filter, flow out from the outlet of filter.Filter must adhere to certain dirt on the filter screen of filter in the course of the work, thereby filter effect is descended.At this moment, need to adopt the method for backwash to make media regeneration, there is following defective in the backwash filter that often uses of people now: 1, when sewage enters filtration barrel body, the heavy particle blow-off pipe of damaging has easily reduced service life of blow-off pipe.2, the filter core bearing capacity is little, can't thoroughly clean filter core.3, unloaded resistance is big, and the water yield of backwash is big, can't guarantee the mobile unobstructed of water.4, complex structure, floor space are big.
Summary of the invention:
Purpose of the present invention just is to provide a kind of pressure reduction, spiral-flow type backwash filter system, and the unloaded pressure loss of this system is little, and the backwash water amount is few, and good filtration effect, and compact conformation are reliable, can carry out backwash under less pressure reduction.
Technical scheme of the present invention is: a kind of pressure reduction, spiral-flow type backwash filter system, comprise filtration barrel body, it is characterized in that: indexing mechanism and transmission mechanism are housed at the top of filtration barrel body, dividing plate is divided into intake antrum and water chamber with inner barrel, even eight groups of filter cores according to circle distribution are housed in the water chamber, on tangential direction, water inlet is set at the water chamber barrel, is provided with sewage draining exit and scale removing mouth in the intake antrum; Sucker is installed between scale removing mouth and the dividing plate, and by the power transmission shaft driven rotary of transmission mechanism.
Inlet pressure gauge is equipped with in above-mentioned water inlet.
Delivery gauge is equipped with at above-mentioned delivery port place, and this Pressure gauge is connected with pressure controller.
The present invention has following advantage and good effect:
1, sewage enters cylindrical shell with the tangent line form, forms eddy flow, and heavy particle falls naturally, is difficult for the blow-off pipe of damaging, and has prolonged the life-span of blow-off pipe.
2, can utilize the pressure of on-line system self, each be crossed filter core carry out backwash one by one, handle the water yield during backwash and change little.
3, can be according to the user to the water purification requirement, the apolegamy filter core reaches the requirement of precision.
4, the filter core bearing capacity is big, and filtration is outwards to be flowed by the filter core center, so filter core can bear elevated pressures.
5, thoroughly efficient recoil, special backwash replenish eddy flow and can wash open filtering slot, have guaranteed the thorough cleaning of filtering element (cartridge), can reach other filter cleaning performance that is beyond one's reach.
6, unloaded resistance is little, and the backwash water yield is few, water mobile unimpeded.When the concentration of suspension of the target in the filtered water≤20mg/L, the backwash quantity of water consumption is filtered percentage ≯ 1% of the water yield.
7, reliable, safeguard that simply main shaft has been adopted self sealing structure, and sealing of spindles can be compensated automatically, long-play can not leak, and does not generally need regular maintenance.
8, install simply, only need to carry out flange with pipeline and be connected, volume takes up an area of to be economized, and does not have other auxiliary device.
9, long service life, the filter core of employing special construction, intensity is big, and is corrosion-resistant, do not have machinery and clean, and avoided the mechanical wear of filter core, and filter core is renewable.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the B-B profile of Fig. 1.
The specific embodiment:
As shown in the figure: a kind of pressure reduction, spiral-flow type backwash filter system, be equipped with motor 2, reductor 3 and indexing mechanism 4 at the top of filtration barrel body 1.Dividing plate 5 is divided into intake antrum 6 and water chamber 7 with filtration barrel body inside, and even eight filter cores 8 according to circle distribution are housed in the water chamber, on tangential direction water inlet 9 is set at the water chamber barrel, is provided with sewage draining exit 10 and scale removing mouth 11 in the intake antrum; Sucker 12 is installed between scale removing mouth and the dividing plate, and by power transmission shaft 13 driven rotary of motor and speed reducer.Inlet pressure gauge 14 is equipped with in above-mentioned water inlet.Delivery gauge 15 is equipped with at above-mentioned delivery port place, and this Pressure gauge is connected with pressure controller 16.
Operation principle of the present invention is: when the sewage that contains solid particle and suspension is squeezed into water cavity by water inlet and cylindrical shell with the tangent line form, current rotate in intake antrum, heavy particle article are sunk naturally, fall into scale removing tube, after sewage was filled with intake antrum, source water just passed through each cup-strainer core, entered water chamber by the water after filtering, when being higher than delivery port, just discharge by delivery port through the water that filters.
Prolongation along with filtration time, the suspension (referring to the suspension greater than filtering accuracy) that is trapped within filter core net inner surface also increases gradually, filter core is blocked gradually, cause the pressure reduction of the inside and outside both sides of filter core to rise gradually, when reaching the backwash differential pressure of setting, control system can be sent the backwash instruction, transmission mechanism drives sucker and rotates, indexing mechanism realizes reaching one by one the position of a filter core, the in good time opening and closing of blowoff valve, under the effect of system self pressure, the water in the water chamber is by filter core backwash outside to inside, and the backwashing water that has impurity is discharged by blowoff valve.Repeat said process, up to all filtering element (cartridge)s all backwash finish.
In the blowdown process, have only a filter core that was covered by sucker to carry out backwash, thereby guaranteed the filtering velocity of filter backwash Inlet and outlet water and handled the water yield to remain unchanged substantially.
