Description

Technical Field

[0001] The utility model relates to the technical field of spirulina cultivation, in particular to a small-scale microalgae balcony cultivation equipment. Background Art

[0002] Spirulina is known as a "green superfood" and "nature's multifunctional health product" because it is rich in nutrients such as protein, chlorophyll, vitamins, minerals and antioxidants, which help to enhance immunity, maintain health and prevent certain diseases. There are two common product forms of spirulina, namely fresh spirulina and spirulina powder. Fresh spirulina is a living food, which is easily contaminated by microorganisms, loses its own activity and is oxidized by chemical components at room temperature. The shelf life is only a few hours, making fresh spirulina almost a luxury.

[0003] However, the existing small-scale spirulina cultivation devices that can be used on family balconies have several fatal defects: first, the manufacturing cost is relatively high, which is unaffordable for ordinary families; second, the cleaning of the spiral tubes is very troublesome and needs to be dismantled one by one for cleaning, which is labor-intensive and time-consuming, and is also prone to damage and leakage; third, the water pumps used for water circulation are all pipeline centrifugal pumps, which have a large shear force and are easy to cut the hair-thin spirulina into pieces, affecting its growth; fourth, the volume of the light-receiving algae liquid in the tubular photobioreactor is very limited (only 20-30 liters), so the output of fresh algae is very limited and cannot meet the edible needs of a family of three. Utility Model Content

[0004] In view of this, the utility model provides a small-scale microalgae balcony breeding equipment, which adopts a barrel-type bioreactor as a spirulina culture container, and has the advantages of large volume, easy cleaning, simple installation and low manufacturing cost. In the process of spirulina growth, only a blower is used for aeration, which does not affect the growth of spirulina. At the same time, multiple barrels are connected in parallel to increase the output of fresh algae, which can basically meet the fresh food needs of small families.

[0005] The technical solution is: a small-scale microalgae balcony breeding equipment, including an algae collection filter, an intelligent electric control box, a special fill light, a water pump, a constant temperature heating tube, a blower, a gate valve and a bioreactor. The output end of the intelligent electric control box is connected to five special fill lights, which are arranged in an array. A bioreactor is placed between every two special fill lights. The four bioreactors are arranged in an array. Gate valves are provided at the bottom of the four bioreactors, which are connected to the inside of the bioreactor. A water pump is placed on one side of the intelligent electric control box. The water inlet of the water pump is connected to the four gate valves. The water outlet of the water pump is connected to the water pump through a conduit. It is connected to four algae collection filter buckets, which are located directly above the bioreactor. The water pump is electrically connected to the intelligent electric control box. Constant temperature heating tubes are placed inside the four bioreactors, and the four constant temperature heating tubes are electrically connected to the intelligent electric control box. A blower is placed on the side of the water pump away from the intelligent electric control box, and the blower is electrically connected to the intelligent electric control box. A multi-way branch pipe is provided at the air outlet of the blower, and the upper part of the multi-way branch pipe of the blower is located in the four bioreactors. Aeration sand balls are provided on the multi-way branch pipes of the blower, and the aeration sand balls of the multi-way branch pipes of the blower are located at the bottom of the bioreactor.

[0006] The beneficial effects are as follows: the utility model adopts a barrel-type bioreactor as a spirulina culture container, which has a large volume, is easy to clean, simple to install, and has a low manufacturing cost. During the growth of spirulina, only a blower is used for aeration, no water pump is needed, and there is no shear force. The water pump is turned on only when the algae are collected, which does not affect the growth of spirulina. The utility model adopts a multi-barrel parallel connection method to make the total capacity of the bioreactor reach 100-120L, and can produce 60-80 grams of fresh algae every day, which can basically meet the fresh food needs of small families.

[0009] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0010] Example 1: A small-scale microalgae cultivation equipment on a balcony, such as Figure 1As shown, it includes main components such as algae collecting filter bucket, intelligent electric control box, special fill light, water pump, constant temperature heating pipe, blower, gate valve and bioreactor. The output end of the intelligent electric control box is connected to five special fill lights, which are arranged in an array. A bioreactor is placed between every two special fill lights. The four bioreactors are arranged in an array. Gate valves are provided at the bottom of the four bioreactors, which are connected to the inside of the bioreactor. A water pump is placed on one side of the intelligent electric control box. The water inlet of the water pump is connected to the four gate valves. The water outlet of the water pump is connected to four algae collecting The filter bucket and the algae collection filter bucket are located directly above the bioreactor, the water pump is electrically connected to the intelligent electric control box, constant temperature heating tubes are placed inside the four bioreactors, and the four constant temperature heating tubes are electrically connected to the intelligent electric control box, a blower is placed on the side of the water pump away from the intelligent electric control box, the blower is electrically connected to the intelligent electric control box, a multi-way branch pipe is provided at the air outlet of the blower, the upper part of the multi-way branch pipe of the blower is located in the four bioreactors, aeration sand balls are provided on the multi-way branch pipes of the blower, and the aeration sand balls of the multi-way branch pipes of the blower are located at the bottom of the bioreactor.

[0011] The bioreactor is made of transparent material and has a capacity of 20-25L. A dustproof cover is provided on the top of the bioreactor, a Φ50mm air hole is provided in the center of the cover, and a Φ20mm overflow hole is provided at the bottom of the bioreactor.

[0012] After the power is turned on, the four constant temperature heating tubes will automatically detect the water temperature in the water, automatically connect (disconnect) the power of the constant temperature heating tubes, and constantly adjust the water temperature. When the four constant temperature heating tubes are installed, all of them are submerged in water without their heads exposed, but the tails should not touch the bottom of the bioreactor, and they should be firmly attached to the rubber pad without loosening.

[0013] Through the blower, multi-way branch and aeration sand ball, one is to provide CO2 to the culture solution water, supplement the carbon source and reduce the amount of sodium bicarbonate; the other is to bring out the dissolved oxygen in the culture solution water, because high concentration of dissolved oxygen will inhibit the photosynthesis of Spirulina.

[0014] Based on the characteristics of Spirulina photosynthesis, we designed a light intensity of 100-300 μmol / m 2 s. The light quality of spirulina is blue light (400-500nm) and red light (620-680nm). The lighting time of four special fill lights is controlled by an intelligent electric control box. Normally, spirulina needs to grow in a cycle of light and darkness. This change in light cycle can increase the growth rate and photosynthesis efficiency of spirulina.

[0015] The intelligent electric control box uses PWM, DS18B20, timer, watchdog and other technologies, and mainly realizes the following functions: LED light color control, light time control, automatic aeration, water temperature monitoring, and water circulation. The system consists of a monitor, a socket controller and a matching mobile phone App. The output end of the intelligent electric control box is connected to a water pump, a constant temperature heating tube, a blower and a special fill light. The signal input end has a temperature sensor input signal and a light sensor signal. The power input end is connected to a 220V power supply.

[0016] The utility model adopts a barrel-type bioreactor as a spirulina culture container, which has a large volume, is easy to clean, simple to install, and has a low manufacturing cost. During the growth of spirulina, only a blower is used for aeration, no water pump is needed, and there is no shear force. The water pump is turned on only when the algae are collected, which does not affect the growth of spirulina. The utility model adopts a multi-barrel parallel connection method to make the total capacity of the bioreactor reach 100-120L, and can produce 60-80 grams of fresh algae every day, which can basically meet the fresh food needs of small families.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
