The invention also aims to provide a method for cleaning the wild monostroma nitidum.

The invention also aims to provide a method for collecting and processing the wild monostroma nitidum.

The above object of the present invention is achieved by the following technical solutions:

a reef membrane cleaning device comprises a tank body and a stirrer; the tank body consists of an upper part body and a lower part body, and the top of the upper part body is provided with a feeding port; the side wall of the lower part of the upper part body is provided with a discharge hole, the bottom of the lower part body is provided with a water outlet, and the side wall of the lower part body is provided with an air inlet which can be connected with an air blower; the stirrer comprises a stirring blade and a stirring motor for driving the stirring blade to rotate, and the stirring blade comprises a first stirring blade, a second stirring blade and a third stirring blade which are respectively positioned at the upper part, the middle part and the lower part of the upper part body; and a net layer structure is arranged at the joint of the cylinder and the cone.

In order to mildly and fully clean the reef membrane, the stirring paddle of the device rotates at the upper, middle and lower parts of the tank body, so that the bottom deposition and the reef membrane thallus can be prevented from being wound mutually and being unfavorable for cleaning. External air enters the tank bottom through the air blower through the air inlet pipe, so that the raw material reef membranes do not sink, and meanwhile, the reef membrane leaves are favorably unfolded and are favorably cleaned. The net layer structure at the joint of the column body and the cone can filter out impurities such as silt and the like, keep the cleaned reef film and directly discharge from the discharge hole at the upper part.

In order to facilitate the placement of the cleaning device, the reef membrane cleaning device can also comprise supporting legs.

In order to avoid the winding of the reef membranes during stirring, the diameter of the tank body is 1m and the height of the tank body is 1.5m relative to the size of a common tank body, the size of the stirring blades is 35cm multiplied by 15cm, and the intervals of the stirring blades are 30-40 cm.

Preferably, the upper body is a cylinder and the lower body is a cone. The bottom of the cone has a certain gradient, so that the washed sediment can be conveniently gathered at the water outlet at the bottom and flows out of the tank body together with the sewage, and the timely sewage discharge is facilitated.

Preferably, the stirring blade is a turbine type spiral baffle. The turbine type spiral baffle changes the tangential flow of algae and increases the turbulence degree of the stirred fluid, thereby improving the turbulence effect.

Preferably, the mesh layer structure is a steel mesh layer, and the mesh size is 4 mm. The aperture size can only let fine sand pass through, avoids the raw materials to run off, and the steel mesh material is corrosion-resistant and can be firmly durable.

A method for cleaning wild monostroma nitidum by using the monostroma nitidum cleaning device comprises the following specific operations: the cleaning process can be that the water-filtering reef membrane is put in from a feeding port according to a certain proportion, for example, 5g of reef membrane is put in 1L of water, when the reef membrane thallus enters water and is unfolded, the reef membrane thallus is fully cleaned through stirring blades and air floating, the washed impurities are filtered and collected through a net layer structure and the bottom of a cone, and the whole washing time can last for 20-30 minutes.

When cleaning, the air flow of the air inlet is 0.5Nm³The air injection frequency is 20-30 min/time. In order to ensure that the reef membranes are fully unfolded in the cleaning process and not to tumble too violently, the air flow is limited to be 0.5Nm³And/h, compared with continuous gas supply, intermittent gas supply can save cost and is beneficial to precipitation and removal of impurities.

Preferably, the wild water-filtering reef membrane is rinsed by adding water before the reef membrane cleaning device is cleaned, the water-filtering reef membrane is placed in a water pool, water is added until the height of a water body is 30-60 cm, and water is fished out after a certain time of natural illumination. When the biomass of the collected wild Monostroma latissimus algae is small, the collected algae is placed in a large water tank, water is added until the height of a water body is 30-60 cm, the algae is subjected to photosynthesis under natural illumination and then is subjected to oxygen release, the thallus floats on a surface layer of the water body, is stretched and is properly stirred, silt and foreign matters fall off, and the size of the water tank is preferably that the algae floats to form a thin layer plane.

When the amount of the reef is small, the reef can be cleaned only by adopting a rinsing mode.

Preferably, the rinsing is seawater cleaning followed by fresh water cleaning. The seawater rinsing can well remove impurities such as silt and the like in the algae, is favorable for saving fresh water resources, and obtains mature and pure seed algae. Mature and pure seed algae are very key to artificial propagation and seedling raising of the hermatypium latifolium, and are very beneficial to prevention and removal of miscellaneous algae (such as enteromorpha) in the process of breeding zygotes or sporangium.
