Abstract
The present invention is the high reliability No clean water strainer of a kind of water system for big flow industrial equipment.In various different use environment, normal filtration and the blowdown work of water strainer can be completed.Drainage screen is without hand sweeping, it is ensured that long trouble free runs.During blowdown, this water strainer is driven a rotatable strainer body by electric device, recoil side plate (6) scraping sieve plate simultaneously (7) wire side, back-flushing progressively back flush sieve plate (7), owing to filter cylinder grid (8) is evenly arranged, foreign material in water strainer are also uniformly distributed in each filter cylinder grid (8), and the tamper of wire side is all removed by back-flushing, and the dirt retained in strainer body is collected by blowdown tank (9) and discharged through blow-off pipe (11).
Description
Technical field
Water strainer is for the water system of big flow industrial equipment, such as power plant, steel mill, paper mill and chemical plant etc..The present invention is a kind of high reliability No clean water strainer, in various different running environment, can complete normal filtration and the blowdown task of water strainer.Drainage screen is without hand sweeping, it is ensured that long trouble free runs.This equipment can be used for field control, is also particularly suitable unmanned control and distant place control.
Background technology
The water source of big flow water system is normally taken from natural river and reservoir, often contains substantial amounts of all kinds of foreign material in water source, uses if directly feeding industrial equipment, it will properly functioning to watering equipment causes strong influence.Therefore must use water strainer that it is filtered.
At present, all there is the problem that drainage screen is gradually blocked by the foreign material crossed in drainage in known water strainer in running.Foreign material on filter screen can not be removed during blowdown by i.e. water strainer the most in time so that the most stifled more many, make supply equipment can not normal water supply, have to be forced out of service, by recovering properly functioning after hand sweeping drainage screen.Thus, the normal work of industrial equipment has been had a strong impact on.
Summary of the invention
It is an object of the invention to provide a kind of can guarantee that in the big flow water system of industrial equipment operation steady in a long-term, without the high reliability No clean water strainer of hand sweeping filter screen.It is applicable to various different water quality environment and different operating conditions.
During blowdown, this water strainer is driven a rotatable strainer body by electric device, recoil dividing plate (6) scraping sieve plate simultaneously (7) wire side, back-flushing progressively back flush sieve plate (7), owing to filter cylinder grid (8) is evenly arranged, foreign material in water strainer are also uniformly distributed in each filter cylinder grid (8), and the tamper of wire side is all removed by back-flushing, and the dirt retained in strainer body is collected by blowdown tank (9) and discharged through blow-off pipe (11).Anti-rotation device (12) prevents the rotation of blowdown tank (9).
Accompanying drawing explanation
Fig. 1 is the overall structure figure of high reliability No clean water strainer.It can be seen that water strainer is supported seat (10), blow-off pipe (11) and anti-rotation device (12) formed by electric device (1), power transmission shaft (2), fluted disc (3), lauter tub lid (4), thrust plate (5), recoil side plate (6), sieve plate (7), filter cylinder grid (8), blowdown tank (9), blowdown tank.
Fig. 2 is the local structural graph of high reliability No clean water strainer.It can be seen that strainer body is supported by blowdown tank (9), intermediate arrangement thrust plate (5).
Fig. 3 is the local structural graph of high reliability No clean water strainer.It can be seen that recoil side plate (6) position can be adjusted, make the adjustable interval of recoil side plate (6) and sieve plate (7).
Fig. 4 is the local structural graph of high reliability No clean water strainer.It can be seen that blowdown tank (9) arranged beneath anti-rotation device (12), the only blowdown tank (9) is made not rotate.
Detailed description of the invention
The structure of the present invention is as shown in Figure of description: water strainer is vertical, and water inlet and arrangement of sewage discharge outlets are arranged in shell upper at outer casing underpart, outlet.Water strainer top layout has electric device (1)；Power transmission shaft (2) it is disposed with between electric device (1) and strainer body；Power transmission shaft (2) is disposed with fluted disc (3)；Filter cylinder grid (8) and sieve plate (7) and filtering cartridge lid (4) are connected as a single entity formation strainer body；Filter cylinder grid is evenly arranged, circumferencial direction be divided into 6-16 lattice；Longitudinal subdivision is 4-8 lattice；Blowdown tank (9) is fixed on blowdown tank and supports on seat (10)；Strainer body is supported by blowdown tank (7), intermediate arrangement thrust plate (5)；Being disposed with two pieces of recoils side plate (6) outside sieve plate (7), the position of recoil side plate (6) can adjust, and it has the evenly spaced circular hole making back-flushing pass through；Sieve plate (7) is made by corrosion resistant plate punching；Blowdown tank (9) arranged beneath anti-rotation device (12)；Electric device (1) directly drives strainer body to rotate.
Water strainer is in running, and water to be filtered is entered by the water inlet of water strainer bottom, enters strainer body inner chamber from the bottom to top, and after screen pack (7), filter cylinder grid (8), the outlet from water strainer top flows out, and completes filter process.
During blowdown, blowdown tank (9) does not rotates, and starts electric device (1), drives strainer body to rotate by drive shaft (2), and when next grating position alignment blowdown tank (9), electric device stall, strainer body also stops the rotation.In strainer body rotary course, the foreign material being blocked in sieve plate (7) mesh are scraped disconnected by recoil side plate (6) in advance.After rotating stopping, sieve plate (7) the most filtered water, the circular hole flowed through in recoil side plate (6) carries out backwash, now can wash out the foreign material in sieve plate (7) mesh smoothly sieve plate (7).Owing to filter cylinder grid (8) is evenly arranged so that the foreign material in water strainer are also uniformly distributed in each filter cylinder grid (8), thus successfully foreign material can be got rid of from blow-off pipe through blowdown tank, thus reach thoroughly to remove the purpose of foreign material.When this is after eliminating impurities, being sequentially completed said process, after whole eliminating impurities, water strainer blowdown process completes.
In strainer body rotary course, in order to preferably scrape the foreign material in the upper mesh of disconnected sieve plate (7), recoil side plate (6) and the adjustable interval of sieve plate (7), adjustment amount is 2-10mm so that it is be maintained in a suitable spacing.
The circular hole of the back-flushing passage in recoil side plate (6) is evenly arranged so that identical by hydraulic pressure on the filter screen wire side of back-flushing effect；Owing to filter cylinder grid (8) is evenly arranged so that the foreign material in water strainer are also uniformly distributed in each filter cylinder grid (8) so that water strainer blowdown can be made during water strainer blowdown thorough, do not stay dead angle.
Strainer body is supported by blowdown tank (9), arranges thrust plate (5) on blowdown tank (9) top so that the kinetic moment driving strainer body to rotate greatly reduces.
