For achieving the above object, the technical solution adopted in the utility model is:
A kind of pollution discharge mechanism of crab cultivation case, comprise casing, sewage sump and blow-off pipe, sewage sump is arranged on casing diapire, and blow-off pipe is arranged on the below of sewage sump, and sewage sump comprises the first segmental arc and the second segmental arc, first segmental arc is connected with wall box lower limb, second segmental arc connects the first segmental arc and blow-off pipe water inlet respectively, and the central angle of the first segmental arc is 30-45 °, and its radius is 30-40cm, the central angle of the second segmental arc is 15-60 °, and its radius is 20-30cm.
The pollution discharge mechanism of crab cultivation case also comprises filter screen, and filter screen is arranged on the sewage draining exit place of described sewage sump.
The mesh diameter of described filter screen is 0.3-0.8cm.
The water inlet of described blow-off pipe is connected with sewage sump, and its water side is provided with water check valve.
The beneficial effects of the utility model are:
The pollution discharge mechanism of a kind of crab cultivation case of the present utility model, comprise casing, sewage sump and blow-off pipe, sewage sump is arranged on casing diapire, blow-off pipe is arranged on the below of sewage sump, sewage sump comprises the first segmental arc and the second segmental arc, first segmental arc is connected with wall box lower limb, second segmental arc connects the first segmental arc and blow-off pipe water inlet respectively, the central angle of the first segmental arc is 30-45 °, its radius is 30-40cm, daily activity can be carried out for crab, the central angle of the second segmental arc is 15-60 °, its radius is 20-30cm, the excreta being conducive to crab enters blow-off pipe along the second segmental arc, timely discharge excreta, ensure the cleaning of the living environment of crab, be conducive to the growth and breeding of crab, increase economic efficiency.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a part of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model pollution discharge mechanism.
In figure:
1-casing; 2-sewage sump; 21-first segmental arc; 22-second segmental arc; 3-filter screen; 4-water check valve; 5-blow-off pipe; 51-water inlet; 52-water side.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the pollution discharge mechanism of a kind of crab cultivation case of the present utility model, comprise casing 1, sewage sump 2 and blow-off pipe 5, sewage sump 2 is arranged on casing 1 diapire, blow-off pipe 5 is arranged on the below of sewage sump 2, sewage sump 2 comprises the first segmental arc 21 and the second segmental arc 22, first segmental arc 21 is connected with casing 1 sidewall lower limb, second segmental arc 22 connects the first segmental arc 21 and blow-off pipe 5 water inlet respectively, the central angle of the first segmental arc 21 is 30-45 °, its radius is 30-40cm, the camber of the first arcwall face formed is less, can facilitate on crab first arcwall face and live, and cambered surface is slope trend, the excreta being conducive to crab to produce on the first arcwall face is discharged, the central angle of the second segmental arc 22 is 15-60 °, its radius is 20-30cm, the arcwall face camber formed is larger, smoothly the excreta that an arcwall face produces can be discharged, ensure the living environment that crab is clean.
