Abstract
The invention discloses a leakproof drainage sieve tube of a high-speed filter. The leakproof drainage sieve tube of the high-speed filter is characterized by comprising a traverse tube, a screen, a vertical tube and an energy-dissipating plate, wherein a downward-bending tube is arranged at one end of the traverse tube; the other end of the traverse tube is the connected end of a center tube of the filter; the downward-bending tube is communicated with the vertical tube; the screen is arranged between the bottom port of the downward-bending tube and the top port of the vertical tube; and the energy-dissipating plate is arranged at the bottom port of the vertical tube. The traverse tube of the leakproof drainage sieve tube is inserted into the center of the high-speed filter; the cleaning water level of the high-speed filter can be automatically reduced; the filter material can be prevented from leaking; the back-flushed filter material is smooth in the surface; and the leakage of a lot of filter materials caused by lifting effect of water pressure or air pressure on the filter layer and water level of the filter during the moment of starting the backflushing procedure of the high-speed filter is well solved. Thus, the supplement quantity of the filter material can be reduced; the backflushing cycle of the filter is prolonged; and water consumption is reduced.
Description
Technical field
The present invention relates to smelting iron and steel technical field, be specifically related to a kind of high rate filter leakproof draining screen casing.
Technical background
At present, the high rate filter using in cold rolling water treatment vehicle, owing to lacking leak-proof device.Cause high rate filter backwash operation to start moment, filtrate can leak outside in a large number.Filtrate leaks for a long time and can cause following technical problem: 1) the continuous attenuation of filtering layer, and effluent quality continues to worsen, and the backwash frequency increases; 2) filtrate that leaks is deposited in backwash water reclaiming system in a large number, forces this system-down desilting; 3) backwash water mud causes heavy wear to filter cloth surface after sweeping along part filtrate to enter into waste water plate and frame filter press, and the filter cloth replacing cycle shortens.
Summary of the invention
The object of the invention is for above-mentioned technical problem, a kind of high rate filter leakproof draining screen casing is provided, this draining screen casing can prevent the moment starting in high rate filter backwash operation, and after the filtering layer parectasis causing due to the unexpected impact of backwash hydraulic pressure or air pressure, filtrate spills.
For realizing this object, the high rate filter leakproof draining screen casing that the present invention is designed, it comprises transverse tube, screen cloth, vertical tube and energy dissipating plate, wherein, one end of described transverse tube is provided with lower bend pipe, and the other end of transverse tube is filter center pipe link, and described lower bend pipe is connected with vertical tube, described screen cloth is arranged between the bottom nozzle of lower bend pipe and the top ports of vertical tube, and described energy dissipating plate is arranged on the bottom nozzle of vertical tube.
Further, described filter center pipe link is provided with angle, between the end face of described transverse tube and the inclined plane of angle, acutangulates.
Further, the bottom nozzle of described lower bend pipe and the top ports of vertical tube are connected by ring flange.
Further, described screen cloth is Double-layer screen.
Further, in described screen cloth, the grid order number of every layer of screen cloth is 9 ~ 11 orders.
Further, in described screen cloth, the grid interlaced arrangement of the grid of ground floor screen cloth and second layer screen cloth.
Transverse tube of the present invention is inserted in the central tube of high rate filter, can automatically reduce high rate filter cleaning water level, prevent filtrate leak, and the filtrate charge level after maintenance backwash is smooth, well solve high rate filter backwash operation and started moment, due to the impact of hydraulic pressure or the air pressure effect of raising to filter filtering layer and water level, the phenomenon and the filtrate causing leaks outside in a large number.So not only can reduce the magnitude of recruitment of filtrate, extend the backwash cycle of filter, reduce water consumption.But also effectively having prevented that filtrate from spilling the adverse effect to subsequent technique, integrated water purifier is realized stable operation and is laid the foundation.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail:
High rate filter leakproof draining screen casing as shown in Figure 1, it comprises transverse tube 1, screen cloth 3, vertical tube 4 and energy dissipating plate 5, wherein, one end of transverse tube 1 is provided with lower bend pipe 1.1, the other end of transverse tube 1 is filter center pipe link 1.2, lower bend pipe 1.1 is connected with vertical tube 4, and screen cloth 3 is arranged between the bottom nozzle of lower bend pipe 1.1 and the top ports of vertical tube 4, and energy dissipating plate 5 is arranged on the bottom nozzle of vertical tube 4.This energy dissipating plate 5 stops up and the concentrated impact of filtered water inlet to filtering layer for preventing the surperficial filtrate accumulation of screen cloth 3, thereby has guaranteed the planarization of high rate filter filtering layer after backwash.
In technique scheme, transverse tube 1, lower bend pipe 1.1 and vertical tube 4 form guiding device, strengthen the current scour to screen cloth 3 surfaces, to guarantee screen cloth 3 water flows.
In technique scheme, filter center pipe link 1.2 is provided with angle 1.3, between the end face of described transverse tube 1 and the inclined plane of angle 1.2, acutangulates.In the time that high rate filter recovers filtration condition, by the preferential lead-in portion water impact screen cloth tamper of above-mentioned angle 1.2, for next draining creates conditions.
In technique scheme, the bottom nozzle of described lower bend pipe 1.1 is connected by ring flange 2 with the top ports of vertical tube 4.
In technique scheme, screen cloth 3 is Double-layer screen.In described screen cloth 3, the grid order number of every layer of screen cloth is 9 ~ 11 orders, is preferably 10 orders, and above-mentioned order number can be guaranteed the rigidity of screen cloth steel wire.In screen cloth 3, the grid interlaced arrangement of the grid of ground floor screen cloth and second layer screen cloth.
When the present invention installs: at the both sides of a high rate filter central tube 10 above-mentioned leakproof draining screen casing of subtend installation respectively.In addition, while startup by in-site measurement high rate filter backwash (washing or air purge) operation, the in fact about 300mm of rise of water level in filter, and accordingly the mouth of pipe drainage position of leakproof draining screen casing is arranged on to 525mm place under high rate filter central tube 10 mouths of pipe.
High rate filter is in the time of backwash, as shown in Figure 2, filter interior water level can be reduced to lower than cloth tank 6 liquid level because of high rate filter central tube 10 bottom valve opens, in the time that backwash operation starts, backwash water or air enter filter bottom by backwash water inlet/air hose 7 places, and after bottom even branch on penetrate filtering layer 8, in the case of external water or air enter, in filter, water can be by leakproof draining screen casing of the present invention, import high rate filter central tube 10, and discharge via backwash outlet pipe 9, whole backwash process middle water level can not exceed cloth tank 6, the filtrate of filtering layer 8 can not leak in high rate filter central tube 10 via cloth tank 6 like this, Double-layer screen has also avoided filtrate to leak from leakproof draining screen casing simultaneously.
In the time that high rate filter recovers filtration condition, the trend of current is contrary during just in time with backwash, in the time that current pass through high rate filter central tube 10 from the bottom to top, angle 1.3 is introduced current in leakproof draining screen casing by filter center pipe link 1.2, and the filtrate being mingled with on screen cloth 3 is cleaned up, for next draining creates conditions.
The content that this description is not described in detail belongs to the known prior art of professional and technical personnel in the field.
