Abstract
The utility model provides an improved laminated filter; the improved laminated filter comprises backwashing tubes, filter sheets, a sealing plate and a base, wherein the plurality of backwashing tubes are uniformly arranged between the sealing plate and the base so as to form an open frame; the plurality of filter sheets are sleeved on the backwashing tubes in a laminated way; the filter sheets are circular platform-shaped annular sheets; a pressing device is arranged above the sealing plate; a one-way water outlet valve is arranged below the base; the one-way water outlet valve comprises a valve plate, a supporting spring and a bottom support; the supporting spring is arranged between the valve plate and the bottom support; through the adoption of the arranged pressing device, the filter sheets are arranged as conical annular sheets; and an upwardly inclined deepened flushing holes are formed in the water outlet pipe; therefore, the service life of equipment is greatly prolonged and the filtering efficiency is increased.
Description
Technical field
The utility model relates to the filter plant field, relates in particular to a kind of taper cross-current type laminated filter.
Background technology
In recent years, laminated filter is widely applied in fields such as wastewater treatment, regeneration effluent, tap water supplies.Because its unique laminated structure filters and the backwash effect can not reduce with the prolongation of service time.A large amount of laminated filter filter discs that use mostly are dull and stereotyped circular ring structure at present, tow sides straight burr groove, and when filter disc was stacked together, the triangle groove of positive and negative was combined and forms the parallelogram mesh.Use spring that filter disc is compressed during filtration, rely on backwash intake pressure Compress Spring that filter disc is unclamped during backwash.
For example Chinese patent ZL200920002872.6 discloses a kind of laminated filter, formed by shell, filter element upper cover, filter core, spring, filter cap, filter core is cylindrical, be laminated by support and the composite wafer that is enclosed within on the support, thin slice is two-sided to be provided with fine and smooth runner, and filter element upper cover is enclosed within on the support, spring places in the filter cap, filter core is pressed on the spring, and filter core places in the shell, and filter cap is connected with shell.
And for example Chinese patent ZL201120224075.X discloses a kind of laminated filter, filters lamination and is enclosed within outside the filter core bucket, and the upper end of filter core bucket is fixed by fixed mount, and fixed mount is inserted in the endoporus of filter core bucket, and the upper end is threaded with the filter core bucket by loam cake.
The deficiency of flat laminated filter:
(1) dull and stereotyped filter disc can be offset when backwash, the compression effect that impact is next;
(2) after spring attachment uses certain hour, flexibility decrease, filter disc compresses deleterious;
(3) equipment appearance dirt amount is little, easily stops up, and backwash is frequent.
Summary of the invention
The utility model provides a kind of dirt amount height that holds for the deficiencies in the prior art in same volume situation, filter area is larger, fastening better effects if, and backwash is improved laminated filter more thoroughly.
The utility model is for solving the problems of the technologies described above, provide following technical scheme: a kind of improved laminated filter, comprise backwash pipe, filter disc, shrouding, base, some backwash pipes evenly are set between shrouding and base form an open frame, some filter disc stacks are socketed on the backwash pipe, it is characterized in that described filter disc is the ring segment of circular table, the shrouding top is provided with hold down gag, the base below is provided with one-way water outlet valve, described one-way water outlet valve is comprised of valve plate, support spring, collet, and support spring is arranged between valve plate and collet.
As further improvement of the utility model, hold down gag is made of cylinder and hold-down head, and the piston rod of cylinder connects hold-down head, and described hold-down head is cylindric being placed on the backwash pipe, and its bottom is the circular table loop configuration matched with filter disc.By this kind setting, effectively overcome prior art and used spring that filter disc is compressed, after using certain hour, spring descends, and causes filter disc to compress the problem of deleterious.
As further improvement of the utility model, the backwash pipe is the cylindrical hollow body, and tube wall is provided with a bar shaped projection, evenly offers from the bottom up the flushing hole that diminishes gradually that communicates with tube cavity on the projection, and described flushing hole is inclined upwardly.By this kind setting, Effective Raise filter disc backwash efficient, extension device service life.
As of the present utility model preferred, backwash pipe quantity is 4.
Be the better technical solutions of the utility model of explaining, below introduce in detail operation principle of the present utility model: filter disc is stacked on backwash pipe and shrouding, on the open frame that base consists of, rely on the circular table loop configuration automatic aligning of filter disc, the shrouding top of filter top end is provided with hold down gag, hold down gag is made of cylinder and hold-down head, cylinder piston rod promotes hold-down head and compresses filter disc, enter filter disc inside after the outer hole coarse filtration of former water by the stacking formation of filter disc, in filter disc, rely on intake pressure to open one-way water outlet valve draining in the filter base after the multiple times of filtration, after filter uses a period of time, the filter course of the stacking formation of filter disc is stopped up by the suspension in the former water and particle easily, it is large that pressure differential between water inlet and the water outlet becomes, filter effect reduces, at this moment need to carry out backwash, cylinder venting during backwash in the hold down gag, hold-down head is retracted, former water enters becomes the backwash water inlet in the filter base, backwash water enters the backwash pipe, flushing hole on the backwash pipe is inclined upwardly, water outlet direction and filter disc form certain angle in the flushing hole, the backwash current produce thrust upwards to filter disc, filter disc is moved to the hold down gag direction, the size of the flushing hole of backwash pipe is directly proportional with the filter disc quantity that needs to promote, flushing hole is larger, the hydro-flow thrust that forms is larger, promotes more filter disc and moves upward.Along with filter disc moves to the hold down gag direction, it is large that gap between each filter disc becomes, current can wash away the particle that accumulation is taken away on the filter disc surface fast, by the acclivitous angle of water of flushing hole on the backwash pipe, filter disc can produce rotation with current, because each filter disc has difference to the flushing hole distance, so rotary speed is different, the rotating speed difference of adjacent filter disc can produce friction, helps the filter disc cleaning surfaces, and the centrifugal force of the simultaneously filter disc of rotation generation also helps the dirt separation on the filter disc, when carrying out filtration operation, hydraulic pressure is greater than the elastic force of support spring, and the spring stress distortion is pressed downward tight, and valve plate sinks, one-way water outlet valve is opened, water (flow) direction is identical with the spring direction when carrying out backwash, and valve plate is closed, and one-way water outlet valve is closed.
The beneficial effects of the utility model: the utility model is by arranging hold down gag, and filter disc is set to conical ring plate, and at outlet pipe acclivitous intensification flushing hole is set, and has greatly prolonged the service life of equipment, has improved filter efficiency.
