Novel production equipment and process for producing water quality improver prepared from oyster shell powder

Abstract

The invention discloses novel production equipment and process for producing a water quality improver prepared from oyster shell powder, and belongs to the field of agriculture. The novel production equipment is characterized in that a shell body is located above a granulation mold to form a closed space, a compression roller assembly is located on the upper surface of the granulation mold and cando rotational motion around the central axis of the granulation mold, and granulation through holes are formed in the positions, corresponding to the compression roller assembly, of the granulation mold; and a grinding assembly is installed on the outer side of the circumference of the compression roller assembly below the shell body and can rotate in the axis direction of the compression rollerassembly, and a first feeding pipeline used for containing blocky oyster shells, a second feeding pipeline used for containing coal cinder and a third feeding pipeline used for containing bentonite are fixedly formed in the lower surface of the shell body. The novel production equipment has the beneficial effects that the oyster shell powder, the coal cinder and the bentonite are mixed and granulated to form oyster shell powder purification blocks with a certain size, the oyster shell powder purification blocks are placed at the bottom of a water body, the slow release of the oyster shell powder can be achieved, the purification effect is stable, and the oyster shell powder purification blocks can be fished out after being used for a period of time and are convenient to recycle.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a novel production equipment and process for producing a water quality improver made from oyster shell powder. Background technique [0002] In the aquaculture industry, due to the relatively dense fish, bait residues, and a large amount of excrement of various organisms, a large amount of organic matter is enriched, and the oxygen consumption of these organic matter increases sharply, resulting in a sharp decrease in dissolved oxygen in water. A large amount of organic matter in the aquaculture water is acidified, resulting in a large number of harmful bacteria. [0003] When the pH value of lake or river water drops below 5, metals (such as aluminum) in the soil and water sediment in the watershed will be dissolved into the water, poisoning fish and seriously affecting their reproduction and development. Acidification of water bodies will also lead to changes in the composition and ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems that oyster shell powder water purifiers in the prior art have large purification workload, low efficiency, unstable purification effect, and the accumulation of purifiers at the bottom of the water body is inconvenient to clean up, the present invention mixes oyster shell powder with cinder and bentonite Granulating, forming a purification block of oyster shell powder with a certain size, and putting it into the bottom of the water body, not only can realize the slow release of oyster shell powder, the purification effect is stable, and after a period of use, it can be salvaged for recycling and reuse
