Embodiment 1

As shown in figs. 1-7, a kind of Simple indoor cement pit Scylla paramamosain sewage filter device, including water pump 1, make unrestrained dress Set the filtering cloth jar 3 of 2 and open-top.The filtering cloth jar 3 and make the same side that unrestrained device 2 is located in cement pit 4, the water pump 1 is located at the other side in pond, through the filtered water purification of filtering cloth jar 3 by make that unrestrained device 2 is diffused into cement pit 4 other Position is fully utilized, and the sewage of generation is finally back in filtering cloth jar 3 through 1 draw-off pump of water pump and is filtered again, thus repeats Circulation.And filtering cloth jar 3, make unrestrained device 2, water pump 1 is respectively positioned on the shorter edge position of pond two sides, so as to be filtered out through filtering cloth jar 3 Water purification is that the Scylla paramamosain cultivated in cement pit 4 makes full use of.The power of water pump 1 will be bought according to the volume size of water body, It is primary by filtering in 3~5h to control the water in cement pit 4.

The filtering cloth jar 3 is length, width and height 3m × 1.5m × 1.2m plastics cylinder, is also designed to other specifications, with specific reference to The size of indoor 4 size of cement pit or the amount of required breeding water body design filtering cloth jar 3.The inside of the filtering cloth jar 3 passes through Partition I 5, partition II 6 are sequentially divided into filter chamber I 3A, filter chamber II 3B and filter chamber III 3C.

Sewage in cement pit 4 is pumped into filter chamber I 3A by the water pump 1 by water inlet pipe 7, the filter chamber III The casing wall of 3C is equipped with the water outlet 8 for making filtered water purification flow back to cement pit 4, and the water outlet 8 is located at filter chamber III 3C Casing wall 3/4 height locate so that flow into filter chamber III in water flow through sufficiently filtering after again from water outlet 8 outflow.It is described Water inlet pipe 7 is made of plastic flexible pipe 71 and plastic rigid pipe 72, and the water inlet end of the plastic flexible pipe 71 is connected with water pump 1, the modeling The water outlet of material hose 71 is connected with plastic rigid pipe 72.The plastic rigid pipe 72 takes the top for being placed on filter chamber I 3A, and with every Plate I 5 is placed in parallel；The position of the endcapped of the plastic rigid pipe 72, the plastic rigid pipe 72 towards filter chamber I 3A opens up There is inlet opening 721, and offers multiple inlet openings 721, and the axle center of the inlet opening 721 along the tube wall direction of plastic rigid pipe 72 Line horizontal by angle α be not less than 30 ° (referring to Fig. 7).The design of above-mentioned inlet opening can be such that sewage was uniformly sprayed at In filter chamber I 3A, and filter cotton had not only been increased to the filter area of water body but also has increased the intracorporal dissolved oxygen of water.

The bottom of the filter chamber I 3A is equipped with activated carbon layer 11, and the top of the activated carbon layer 11 is equipped with fine sand layer The top of I 10, the fine sand layer I 10 are equipped with filter cotton 9.The bottom of the filter chamber II 3B is equipped with spongy layer 12, institute The top for stating spongy layer 12 is equipped with gravelstone sublayer 13, and the top of the gravelstone sublayer 13 is equipped with fine sand layer II 14.The mistake Activated carbon packet 15 is placed in filter chamber III 3C, the activated carbon packet 15 is made of gauze package activated carbon, the activated carbon packet 15 be a packet or more packets, and the size and supply volume of activated carbon packet 15 are determined according to the volume of filter chamber III 3C.Fine sand and mistake Filter pulp can be filtered the large particulate matter in water body, the finely ground particle substance in the adsorbable water body of grain active carbon, on sponge Beneficial microbe can be adhered to digest and assimilate the intracorporal ammonia nitrogen of water, integrally reach purpose of purifying the water quality.Also, it is described It is equipped with the gauze I 16 of 200 mesh between filter cotton 9 and fine sand layer I 10, is spread between the fine sand layer I 10 and activated carbon layer 11 Gauze II 17 equipped with 200 mesh is equipped with the gauze III 18 of 200 mesh between the spongy layer 12 and gravelstone sublayer 13, described The gauze IV 19 of 200 mesh is equipped between gravelstone sublayer 13 and fine sand layer II 14.Gauze I 16, gauze II 17, gauze III 18, the setting of gauze IV 19 can effectively prevent the filter layer diffusion of adjacent interfaces to obscure, and after a period of time convenient to use, The replacement of some or multiple filter layers.

The volume ratio of filter chamber I 3A, filter chamber II 3B and filter chamber III 3C are 1: 2: 1 (i.e. 3 filter chambers Width ratio is 1:2:1, equal length).The partition I 5, partition II 6 side wall be connected with the casing wall of filtering cloth jar 3, institute The bottom for stating partition I 5 is not contacted with the bottom surface of filtering cloth jar 3, and the bottom of the distance from bottom filtering cloth jar 3 of the partition I 5 Apparent height accounts for the 1/4 of 3 total height of filtering cloth jar, to ensure the water body in filter chamber I 3A successively through filter cotton 9, fine sand layer I 10, it is flowed into filter chamber II 3B after activated carbon layer 11 filters from bottom.Also, the side of the spongy layer 12 and filter chamber I The activated carbon layer 11 of 3A connects, between the bottom insertion spongy layer 12 and activated carbon layer 11 of the partition I 5, and it is small for stopping Pars layer 12 and activated carbon layer 11, to ensure through filter cotton 9 and the filtered water body of fine sand layer I 10 by activated carbon After 11 filtering of layer, then flow into spongy layer 12.The top of the partition I 5 is flushed with the top of filtering cloth jar 3, the partition II's 6 Overhead height is lower than the overhead height of filtering cloth jar 3, and the top of the partition II 6 is located at 4/5 height of filtering cloth jar 3, described The overhead height of partition II 6 is higher than the height of water outlet 8.Due to the difference in height of water body in filter chamber I 3A and filter chamber II 3B (i.e. water height in filter chamber I 3A is higher than the water height in filter chamber II 3B), make to flow into the bottom filter chamber II 3B Water body is gradually increasing, and successively after spongy layer 12, gravelstone sublayer 13 and fine sand layer II 14 filtering, finally covers partition II 6 Top flow into filter chamber III 3C in.

The operation logic of the utility model: being extracted into sewage in plastic rigid pipe 72 using water pump 1 from cement pit 4, then from It is uniformly sprayed at multiple inlet openings 721 below 72 tube wall of plastic rigid pipe in filter chamber I 3A, sewage successively passes through filter cotton 9, fine sand layer I 10, activated carbon layer 11 filter, and the lower section then through partition I 5 enters in the spongy layer 12 in filter chamber II 3B； Since that there are liquid levels is poor for the water body in filter chamber I 3A and filter chamber II 3B, the water body in filter chamber II 3B passes through gravelstone sublayer 13, continue to rise after fine sand layer II 14, the top for then covering partition II 6 flows into filter chamber III 3C；Flow into filter chamber Water body is further purified through activated carbon packet 15 in III 3C, is increased with rate of water added, the water level in filter chamber III 3C is gradually increasing To the position of water outlet 8, the water purification for filtering acquisition is back in cement pit 4 by water outlet 8；It is back to net in cement pit 4 Water is utilized by other regions that unrestrained device 2 is diffused into cement pit 4 of making on side by Scylla paramamosain biology, the dirt of generation Water enters in filtering cloth jar 3 through water pump 1 again to be filtered again, thus repetitive cycling, is formed one and is continued, flowing, stable follows Ring water filtering system.

The foregoing is merely the preferred embodiments of utility model, are not intended to limit the utility model, all in this reality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the utility model Within protection scope.
