Description
Technical field
The present invention relates to a kind of strainer, particularly a kind of biological flocculation strainer.
Background technology
In the process of carrying out aquaculture, need to use filtration unit to carry out circulating filtration to aquaculture water, adopt biological flocculation to be exactly one wherein as the strainer of filter material.Traditional biological flocculation filtration device structure is relatively simple, and be only place a certain amount of biological flocculation in a vessel, current are after biological flocculation, and the impurity be mingled with in it just can be adsorbed by biological flocculation, reach the effect purified water.But traditional biological flocculation strainer in use for some time, have a large amount of impurity or contaminants adhere at biological flocculation and water-in, water outlet, affect filter effect, cleaning gets up extremely to bother.Therefore now a kind of new bio floc sedimentation filtration device structure that can solve the problem is needed.
Summary of the invention
The present invention is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of can to carry out and recoils and blowdown, the biological flocculation strainer of guarantee filter effect.
Technical solution of the present invention is: a kind of biological flocculation strainer, comprise columniform filter body 1, it is characterized in that: be provided with in described filter body 1 and filter inner core 2, the top of filtering inner core 2 is provided with the water inlet pipe 3 communicated with its inner chamber, the bottom of filter body 1 is provided with water shoot 9, the catch basin 4 of inverted cone shape is provided with in the bottom of filtering inner core 2, be provided with between catch basin 4 and the inner chamber filtering inner core 2 and be with porose base plate 7, with the blow-off pipe 5 be provided with valve of catch basin 4 intracavity inter-connection, the hole that multiple pore size is 0.5-1cm is offered at the surface uniform filtering inner core 2, screen cloth 6 is also provided with outside filtration inner core 2, the mesh size of screen cloth 6 is 300 orders, biochemistry filtered ball 8 is filled in the inner chamber filtering inner core 2, the upper cover 11 of filter body 1 is provided with at circumferentially equally distributed multiple recoil mouth 10, recoil mouth 10 is between screen cloth 6 and filter body 1.
Compared with the existing technology, tool has the following advantages in the present invention:
The biological flocculation strainer of this kind of structure formation, for the filtration unit of traditional employing biological flocculation as filter material, add the structure of blowdown and recoil, also set up the screen cloth of certain order number outer tube simultaneously, improve filtration, while interdiction capability, recoil cleaning can also be carried out in use for some time to filtration inner core and screen cloth, scale removal process is simple, fast, save work, and its manufacture craft is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market outlook are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.As shown in Figure 1: a kind of biological flocculation strainer, comprise columniform filter body 1, be provided with in filter body 1 inside and be similarly columniform filtration inner core 2, the top of filtering inner core 2 is provided with the water inlet pipe 3 with the intracavity inter-connection filtering inner core 2, the bottom of filter body 1 is provided with water shoot 9, the catch basin 4 of inverted cone shape is provided with in the bottom of filtering inner core 2, and base plate 7 is also provided with between catch basin 4 and the inner chamber filtering inner core 2, this base plate 7 is evenly distributed with multiple hole, with the blow-off pipe 5 be provided with valve of the intracavity inter-connection of catch basin 4, filter inner core 2 uniformly offer the hole that multiple pore size is 0.5-1cm, and screen cloth 6 is also provided with outside filtration inner core 2, the mesh size of this screen cloth 6 is 300 orders, and in the inner chamber filtering inner core 2, filled biochemistry filtered ball 8, the upper cover 11 of filter body 1 is also provided with multiple recoil mouth 10, and these recoil mouths 10 are circumferentially being uniformly distributed, recoil mouth 10 is between screen cloth 6 and filter body 1.
The working process of the biological flocculation strainer of the embodiment of the present invention is as follows: the water body in aquaculture pond is under the effect of water pump, being entered by water inlet pipe 3 filters in inner core 2, and filter under the effect of filtering the biochemistry filtered ball 8 in inner core 2, impurity in water body, dirt etc. can be adsorbed by biochemistry filtered ball 8, and water body pure after filtering is discharged from the hole of filtering inner core 2, after screen cloth 6 carries out secondary filtration, discharged by water shoot 9;
This kind of biological flocculation strainer in use for some time, filter on inner core 2 and screen cloth 6 and can adhere to a large amount of dirts, these dirts can hinder passing through of current, affect filter effect, now only need to stop to water filling in strainer, then open recoil mouth 10, in filter body 1, pour into high-pressure water body by recoil mouth 10, water body carries out back scour to filtration inner core 2 and screen cloth 6, and the dirt adhered to thereon just can be washed down; And this part dirt and the tiny dirt that produces in course of normal operation are by after base plate 7, can deposit in catch basin 4, open the valve on blow-off pipe 5, the dirt in such catch basin 4 just together together can be discharged by blow-off pipe 5 in company with water body, realizes the cleaning of strainer.
