Forming technology and production device for circulating water fish farming water tank

Abstract

The invention discloses a forming technology and a production device for a circulating water fish farming water tank. A curing technology can be adapted to products of different shapes and volumes through customized gradient heating. The production device of the framing water tank comprises a forming device and a traction device, the forming device comprises a temperature equalizing device, a preformed die and a formed die, the resin in the inner layer of the product is fully heated through the temperature equalizing device, and the stress concentration cracking caused by the internal and external temperature difference is avoided; the product is primarily cured through the pre-formed die and further extruded and compacted, the surface defect caused by the internal residual bubbles or theinsufficient filling is avoided, through the multi-layer composite design of the cutter blades, the problem of accelerating the wear due to the fact that the cooling is not in time due to the long-term cutting of the blades is overcome, and the overall structural strength of the cutting blades is also ensured; and by means of production device of the framing water tank of the forming method, theyield is high, the process adaptability is high, and the solid technical support is provided for the promotion and popularization of the advanced aquaculture.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a forming process and production device for a circulating water fish breeding tank. Background technique [0002] With the development of society, the aquaculture industry is booming and its scale is expanding day by day, but its impact on the ecological environment is also increasing. Under the traditional farming mode, feces, residual bait, and fish medicine produced by fish feeding enter into large water bodies such as ponds, reservoirs, and lakes, which will increase the ecological load of the water body, resulting in eutrophication of the water body and deterioration of water quality. As the country pays more attention to the protection of water resources and the environment, this extensive and polluting traditional farming model will be gradually banned. [0003] The circulating aquaculture model in the pond is a small-area high-density farming, low-density ecological, and circu...

Problems solved by technology

In addition, the existing circulating culture technology in ponds mostly uses cement or brick-concrete to build water tanks and other facilities. Not only is the construction difficult, the construction period is long, and it cannot be transported, but the side walls of cement materials are easy to scratch fish scales and make fish suffer from water. mildew, which brings great economic losses to farmers, and the cement structure is not conducive to the addition and installation of intelligent equipment and pipelines in the later stage

At the same time, there is no mature component production device and process matching the aquaculture tank on the market. This problem significantly increases the initial equipment investment, which is not conducive to the rapid replication and promotion of running water fish aquaculture
