Abstract
The utility model relates to a self-cleaning spiral-flow filter, which is used for filtering the liquid (gas) and the solid phase fluid of the industrial production. The self-cleaning spiral-flow filter is provided with a columnar filtering casing; a filtrate outlet is arranged on the top of the casing; the bottom of the casing is provided with a filter residue outlet; a value used for releasing filter residue is arranged on the bottom of the casing; the middle lower part of the casing is provided with a filtrate inlet which is installed by a tangent; the middle upper part of the casing is provided with a filter value component breadthwise; the upper part of the casing is provided with a cleaning pipe. The self-cleaning spiral-flow filter has the advantages of small filtration resistance, good filtration effect, high productive efficiency, and simple structure. The self-cleaning spiral-flow filter can be cleaned automatically, and can release filter residue at any time. The utility model is suitable for various production occasions.
Description
The utility model relates to the separator of non-homogeneous phase fluid, especially with liquid (gas)---the solid phase fluid filter is relevant.
At present, using the twin filter to liquid (gas)---the solid phase fluid filters, mainly is the production occasion at technological process requirement filter pipeline.Because this filter has two to filter the valve cylinder and the use that can intersect, so can safeguard the continuous operation of producing.But because this filter does not have slag-drip opening, safeguard continuous filtration, just must usually clean or change blocked filter screen, this makes troubles to production operation.Also owing to can not remove the filter residue factors that are deposited on the filter screen at any time, make filtration resistance bigger than normal in addition.
O, L45-1 type Jenag strainer that China Chongqing Chemical Machinery Plant produces provide a kind of filter that is provided with sludge outlet and self-cleaning structure.This filter is a upright filter chamber, middle is divided into cup and chamber, back by filter, and institute's filtrate material is by cup chamber and filtering through filter screen is drawn onto after, and adopts filtrate shunting to refund the cleaning filter screen, and filter residue can be removed at any time.But because the institute filtrate material direction of motion and filtering direction are in the same way, add that filter liquor need shunt scarfing cinder again, filter efficiency is affected.This filtering machine structure more complicated, the cost height, and be not suitable for use in the filter pipeline use.
The purpose of this utility model is to provide a kind of filtration resistance little, production efficiency height, scarfing cinder at any time, and self-cleaning type spiral-flow filter simple in structure, that be suitable for multiple production occasion use.
Self-cleaning type spiral-flow filter of the present utility model, it has a cylindrical filtration housing, has the filtrate import that tangent line is provided with in the housing middle and lower part, and the top has filtrate (liquid, and the bottom has sludge outlet and installs residual cake valve.Housing middle and upper part horizontally set sieve element, top is provided with at least one scavenge pipe.
Fig. 1 is a self-cleaning type spiral-flow filter structural representation.
With reference to Fig. 1, filtering housing 2 is that two ends are taper or hemispheric cylinder, and its top has filtrate (liquid 1, and bottom center has sludge outlet 6, exit installing ball core valve 7.The cylindrical section bottom of housing 2 has filtrate import 4, and this import and cylinder horizontal cross-section tangentially are provided with.Support ring 3 is installed on housing 2 middle parts and affixed, and support ring 3 is used for fixing filter element 5.Filter element 5 is made of screen holder and filter screen.Screen holder is a hollow cylinder with holes, and its lower floor, upper strata and side face coat with filter screen.The filter screen number of plies can be by the manufacturing technique requirent setting, and is at regular intervals between layer and the layer, and filter screen (mesh is ascending) from coarse to fine upwards (and outer) is arranged.On housing 2, be positioned at the Pressure gauge 8 that 5 times installings of sieve element are provided with observing the preceding pressure of filter, be positioned at two scavenge pipes 9 of installing on the sieve element 5.
Institute's filtrate material pumps into filtrate import 4 by pump, and enters filtrate housing 2 with tangential direction.The attitude that the liquid material rises in the shape of a spiral, rotation make solid shape grain through the center gathering and to deposit; Liquid upwards flows out from filtrate (liquid 1 through sieve element 5.
When needs are got rid of filter residue, open the ball core valve 7 on the sludge outlet 6, promptly utilize filtrate refluence to clean voluntarily and deslagging.The discharging of filter residue can be according to the production technology situation, carries out when stopping to filter or when filtering.When stopping to filter, open ball core valve 7, open the scavenge pipe 9 that is communicated with atmosphere again, lasted for 5～10 seconds, filter residue can drain.When filtering, as long as open ball core valve 7, lasted for 5～10 seconds, filter residue can drain.
If Pressure gauge 8 is higher than normally-pressured neighbor before finding filter, show that then sieve element 5 needs to clean.Can use various suitable cleaning agents, clean as water, air, steam, alcohol, gasoline etc.During cleaning, close filtrate (liquid 1, open ball core valve 7, open the scavenge pipe 9 that connects cleaning agent again, cleaning agent injects and filters housing 2, and filter screen is cleaned.
Self-cleaning type spiral-flow filter of the present utility model also is suitable for gas---the filtration of solid phase fluid.
According to the self-cleaning type spiral-flow filter of the utility model design and since adopt from bottom to top filter type and the filtrate import of tangent line, all make filter residue be difficult for being deposited on filter screen, and filtration resistance lowered.The design has also adopted the large tracts of land filter structure that filtrate is reduced in the speed of filtering direction, and filtration resistance has fallen sharply.The design is simple in structure, cost is low, good filtration effect, production efficiency height.
Claims (2)
1, a kind of self-cleaning type spiral-flow filter, has the filtration housing that filtrate is imported and exported, housing bottom has sludge outlet and installs residual cake valve, installing sieve element in the housing, it is characterized in that: filtering housing (2) is a cylinder, and its top has filtrate (liquid (1), and the middle and lower part has the filtrate import (4) that tangent line is provided with, middle and upper part horizontally set sieve element (5), top are equipped with a scavenge pipe (9) at least.
2, by the described self-cleaning type spiral-flow filter of claim 1, it is characterized in that: filtration housing (2) preferably two ends is taper or hemispheric cylinder.
