Abstract

The utility model discloses a pollution suction device at the bottom of an aquiculture seedling rearing pond. Six pairs of plastic baffle plates are welded on the bottom surface of a rectangular hard plastic plate, wherein the four pairs of plastic baffle plates and a middle pollution discharge port are in radial cross arrangement, the two pairs of plastic baffle plates are respectively positioned on the sides of short edges, sponges are fixed on each pair of baffle plates, a circular pollution suction port is arranged at the middle, the front surface of the plastic plate is connected with the pollution suction port through a flexible pipe, a splayed movable support which is formed by bending steel bars is fixed by plastic footings, and the support is bound on a wood handle. Compared with the existing pollution suction device, the pollution suction device disclosed by the utility model can be used for not only solving the original problem of non-thorough pollution suction and improving the pollution clearance rate from 60% to 92%, but also tripling the pollution suction working efficiency.

Description

Dirt-absorber at the bottom of the aquaculture nursery pond

[technical field]

The utility model belongs to aquaculture field, relates to a kind of dirt-absorber at the bottom of the pond that is applied in aquatic fry growing and the industrial aquaculture to culture.

[background technology]

The aquatic products industrial aquaculture with grow seedlings, have a large amount of mud at the bottom of the pond, constitute by residual bait, ight soil, biological corpse, pathogenetic bacteria and virion etc.These mud are itrogenous organic substances, under the effect of bacterium, be decomposed into the material very harmful to fishes and shrimps such as ammonia nitrogen, nitrous acid nitrogen, hydrogen sulphide, and these mud also are the hotbeds of bacterium, virus breeding.So in time remove mud is extremely important work in the industrial aquaculture and the production of growing seedlings.

The present mode of removing contamination mainly contains two kinds, and one of which is established sewage draining exit for pond central authorities, but how slow and dirt sticks at poor effect at the bottom of the pond because of water flow velocity; It two is to be connected with flexible pipe is vertical with the semicircular short tube of moulding firmly, processes T-shaped dirt-absorber, utilizes the siphon principle soil pick-up, also exists because of striking off dirt with hard plastic tube not thoroughly and problem such as work efficiency is low.

[summary of the invention]

The purpose of the utility model is, design a kind of can be fast and effectively absorb the dirt-absorber of dirt at the bottom of the pond, to address the above problem.

The utility model is realized through following method: 6 pairs of plastic dam of welding in rectangle hard plastic board bottom surface, and wherein, 4 pairs of sewage draining exits with the centre are radial cross arrangement; 2 pairs lay respectively at minor face one side; Fixing sponge on every pair of baffle plate, the centre is circular sewage discharge tube, moulds the positive tube socket sewage discharge tube of using of plate; With the fixing splayed travel(l)ing rest that is curved by reinforcing bar of plastics footing, support is strapped on the wood handle.

The beneficial effect of the utility model is: at the bottom of culturing the pond, move forward and backward dirt-absorber with wood handle in proper order; Sponge brush through the dirt-absorber bottom plays dirt; Along with moving of dirt-absorber; Dirt focuses on the sewage discharge tube zone before and after it under the rule bundle of the dirty baffle plate of collection, under the suction of syphonic water flow, is drawn onto outside the pond.The present invention compares with existing dirt-absorber, has not only solved the not thorough problem of original soil pick-up, and the dirt removal rate brings up to 92% by 60%, and has improved 3 times of soil pick-up operating efficiencies.

[description of drawings]

Figure of description is the structural representation of the utility model, and wherein Fig. 1 is a schematic bottom view, and Fig. 2 is a front schematic view.

Among Fig. 1: the dirty baffle plate of 1-soil pick-up flexible pipe, 2-plastic front board, 3-collection, 5-sewage discharge tube, 6-remove contamination sponge, 8-wood handle.

Among Fig. 2: 1-soil pick-up flexible pipe, 2-plastic front board, 4-plastics footing, 5-sewage discharge tube, 7-Steel bar rack, 8-wood handle.

[embodiment]

Be described in detail the structure and the method for using of dirt-absorber at the bottom of the utility model aquaculture nursery pond below:

This device be thickness be the 10mm rectangle (450mm * 300mm) moulds 6 pairs of plastic dam of plate bottom surface welding, wherein, 4 pairs be positioned at central sewage draining exit and be radial cross arrangement; 2 pairs lay respectively at minor face one side, and with the fixing sponge of screw, sponge covers baffle plate on every pair of baffle plate; And expose 40mm, the centre is circular sewage discharge tube, moulds the positive tube socket sewage discharge tube of using of plate; Use the fixing splayed travel(l)ing rest that is curved as the reinforcing bar of 4mm by diameter of plastics footing, support is strapped on the wood handle.

Concrete operations are following: move forward and backward in proper order at the bottom of culturing the pond with wood handle; Sponge brush through the dirt-absorber bottom plays dirt, and along with moving of dirt-absorber, dirt is under the rule bundle of the dirty baffle plate of collection before and after it; Focus on the sewage discharge tube zone, under the suction of syphonic water flow, be drawn onto outside the pond.The present invention compares with existing dirt-absorber, has not only solved the not thorough problem of original soil pick-up, and the dirt removal rate brings up to 92% by 60%, and has improved 2 times of soil pick-up operating efficiencies.

2010～2011, prosperous Yongfeng, Tianjin aquaculture Co., Ltd used this device and carries out lefteye flounder, Cynoglossus semilaevis, prawn seed-rearing and breed, and the effect of removing contamination is remarkable.Year breeding water body is 20,000 m ³, totally 8 workshops, 2 dirt-absorbers of each workshop configuration.Day rate of water exchange reduces to 50% by 80%.The work efficiency of removing contamination is also by everyone needs man-hour 12h to be reduced to 4h between per car.This device has been generalized to the 20m altogether of 8 companies of periphery in 2011 ³Breeding water body.
