Feeding device, facility and method

Abstract

The invention relates to the technical field of feeding devices, in particular to a feeding device, facility and method which are applicable to large-scale indoor feeding of larvae of aquatic fireflies. The feeding device comprises a feeding rack, a filter water tank, a disinfection water tank and a purification water tank, wherein multiple feeding boxes are forwards obliquely placed on the feeding rack, overflow ports are formed in front walls of the feeding boxes, a water receiving tank is located in the feeding rack and right below the overflow ports of the feeding boxes, a water pipe support is arranged on the feeding rack, a water supply pipe is mounted on the water pipe support, multiple faucets are led out of the water supply pipe, each faucet is located right above one feeding boxcorrespondingly, the water receiving tank is communicated with the filter water tank, and water drained from the filter water tank sequentially passes through the disinfection water tank and the purification water tank to flow back to the water supply pipe. Water is purified by the disinfection water tank and the filter water tank, the purified water flows into the feeding boxes again after passing through a water circulation system, so that the water resource is fully utilized, and the problem that larvae of fireflies dead easily due to water deterioration is solved.

Description

technical field [0001] The invention relates to the technical field of feeding devices, in particular to a feeding device, a feeding facility and a method, which are suitable for large-scale indoor feeding of aquatic firefly larvae. Background technique [0002] Fireflies, especially aquatic fireflies, are environmental indicator organisms. However, due to the destruction of the environment, the survival of fireflies is facing a severe test. Under the condition that more and more attention is paid to environmental restoration, a large number of firefly sources are needed to restore fireflies, but there is no relevant technical system for large-scale indoor breeding of fireflies. [0003] The invention patent with the patent number ZL201420601117.0 discloses a firefly recirculating aquaculture device. The breeding device includes four upright tubes, a screen and a water tank. The screen is fixed on the upper part of the four upright tubes to form a bottomless culture frame. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of this practical invention is to overcome the above-mentioned problems in the prior art and provide a breeding device, breeding facility and method. The present invention can filter and sterilize the water flowing out of the breeding box, and then pass the sterilized water through the water delivery pipe Send it back to the breeding box to solve the problem that the firefly larvae are easy to die due to the deterioration of water quality
