Abstract

The utility model discloses a spiral-flow type back washing filtering device. A dividing mechanism and a drive mechanism are installed at the top of a filter cylinder body, the inside of the filter cylinder body is divided into a water inlet cavity and a water outlet cavity by a baffle plate, eight filter elements which are uniformly and circumferentially distributed are installed in the water outlet cavity, a water inlet is arranged on the cylinder wall of the water outlet cavity along a tangent direction, and a drain outlet and a fouling outlet are arranged in the water inlet cavity; and a suction cup is installed between the fouling outlet and the baffle plate and is driven by a drive shaft of the drive mechanism to rotate. By adopting the structure of eight groups of filter elements and applying the principle of fluid mechanics, the device has less idle load pressure loss, less water consumption of back washing, favorable filtering effect, compact structure and reliable operation and can carry out the back washing under the condition of a smaller differential pressure.

Description

The spiral-flow type back-flushing filtering device
Technical field:
The utility model relates to a kind of sewage disposal device, particularly a kind of spiral-flow type back-flushing filtering device.
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:
The purpose of this utility model just is to provide a kind of spiral-flow type back-flushing filtering device, and this installs, and the unloaded pressure loss 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.
The technical solution of the utility model is: a kind of spiral-flow type back-flushing filtering device, 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 utlity model 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 utility model.
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 spiral-flow type back-flushing filtering device, 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 utility model 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.
