Description

Technical Field

[0001] The invention belongs to the technical field of chlorella cultivation, in particular to a chlorella cultivation device. Background Art

[0002] Chlorella is a single-cell green algae belonging to the Chlorophyta. Chlorella has strong photosynthesis ability and reproduces quickly. At present, during the cultivation process of Chlorella, Chlorella needs sufficient light source, ventilation, suitable temperature and other conditions to ensure the efficient reproduction rate of Chlorella.

[0003] The patent with publication number CN219907615U discloses a culture box for Chlorella, including a box body, in which an oxygen supply and aeration device, a rotary stirring device and a circulation filtering device are sequentially arranged; the oxygen supply and aeration device provides oxygen and other required gases for the cultivation of Chlorella in the box, the rotary stirring device enables the Chlorella in the box to be fully mixed with the nutrient solution, accelerates the reproduction speed of the Chlorella, purifies the culture water in the box through the circulation filtering device, and then transports the purified culture water back to the box, thereby ensuring the water quality of the culture water in the box and further improving the yield quality of Chlorella.

[0004] In the above scheme, when Chlorella is cultivated, a growth lamp installed inside the box provides a light source for the reproduction of Chlorella. Since the light coverage area emitted by the growth lamp is limited, the Chlorella in the box cannot be completely exposed to the light, resulting in uneven exposure of the Chlorella to light, resulting in a decrease in the photosynthetic rate of some Chlorella, thereby affecting the overall reproduction rate. For this reason, the present invention provides a Chlorella cultivation device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve the technical problem is as follows: the chlorella cultivation device described in the present invention comprises a cultivation box, an air inlet pipe and a water outlet pipe are arranged in the cultivation box, and a feed nozzle is arranged on one side of the cultivation box, one end of the water outlet pipe is connected to the water inlet end of a water pump, and the water outlet end of the water pump is connected to a circulating lighting mechanism, and the circulating lighting mechanism comprises a support frame, one end of the support frame is fixedly connected to the cultivation box, a U-shaped pipe fixedly installed on the support frame, six groups of U-shaped glass tubes fixedly installed on the U-shaped pipe, the inside of the U-shaped glass tube is connected to the inside of the U-shaped pipe, one end of the U-shaped pipe is connected to the water outlet end of the water pump, and the other end of the U-shaped pipe extends into the cultivation box, and three groups of plant growth lamps are arranged between the six groups of U-shaped glass tubes, and the plant growth lamps are fixedly installed on the support frame;

[0007] During the cultivation process of Chlorella, the Chlorella will flow through six groups of U-shaped glass tubes in sequence with the mixed liquid, and the U-shaped glass tubes are all exposed to light. The Chlorella is dispersed in the six groups of U-shaped glass tubes, which not only increases the contact area between the Chlorella and the light, but also makes the Chlorella receive light more evenly, thereby increasing the photosynthetic rate of the Chlorella, thereby accelerating the overall reproduction rate of the Chlorella.

[0008] Preferably, the U-shaped pipeline includes a main pipe, which is fixedly mounted on a support frame, six groups of rotary pipes rotatably sleeved on the main pipe, two groups of rotary nozzles symmetrically arranged on the rotary pipe, an arc partition fixedly mounted in the main pipe, two groups of sealing rubber sleeves symmetrically fixedly mounted in the rotary pipe, one end of the main pipe is connected to the water outlet of the water pump, and the other end of the main pipe extends into the incubator, the inner circle of the arc partition fits the outer circle of the main pipe, the main pipe passes through the sealing rubber sleeve, and the inner circle of the sealing rubber sleeve is close to the outer circle of the main pipe, a plurality of groups of openings are opened on the main pipe, the rotary nozzle is located directly below the opening, and a screw sleeve is movably sleeved on the end of the U-shaped glass tube, and the screw sleeve is used to screw the rotary nozzle;

[0009] Preferably, since the end of the U-shaped glass tube is facing downward, on the one hand, the mixed liquid in the U-shaped glass tube can be directly discharged, thereby improving the cleaning efficiency of the U-shaped glass tube; on the other hand, the mixed liquid flowing in the main tube cannot enter the U-shaped glass tube, and the flowing mixed liquid will flow directly through the rotary tube into the next group of rotary tubes, so that the illumination of the Chlorella can proceed normally, thereby ensuring the illumination rate of the Chlorella.

[0010] Preferably, both ends of the rotating tube are provided with a limit mechanism, the limit mechanism comprises a fixing sleeve, the fixing sleeve is fixedly sleeved on the main pipe, a plurality of groups of bevel teeth are arranged at equal angles on the outer ring of the fixing sleeve, a claw that clamps the bevel teeth, a flap, and one end of the claw is clamped with the bevel teeth, the bevel teeth consist of a plurality of groups of short teeth and a group of long teeth. The other end of the claw is fixedly connected to the flap, a first U-shaped elastic bar is arranged on one side of the claw, and is used for limiting the flap. A second U-shaped elastic bar is arranged on one side of the limiting plate, and is used for pushing an unlocking rod of the limit plate, and a blocking plate fixedly connected to the unlocking rod. The claw and the limit plate are both hingedly connected to the inner wall of the rotating tube, the first U-shaped elastic bar and the second U-shaped elastic bar are both fixedly installed in the end of the rotating tube, an inclined surface is arranged at the end of the limiting plate, the blocking plate is fixedly sleeved on the main pipe, and the blocking plate fits the end face of the rotating tube, an arc groove is opened on the fixing sleeve, the arc groove is slidably connected to the limit rod, and the limit rod is fixedly connected to the rotating tube;

[0011] During the disassembly of the U-shaped glass tube, the short teeth will limit the claws that move back. When the staff loses control, the U-shaped glass tube cannot rotate back, thereby avoiding the collision between the U-shaped glass tube and the plant growth lamp. Secondly, since the short teeth limit the claws, the staff does not need to hold the U-shaped glass tube all the time while waiting for the mixed liquid in the U-shaped glass tube to be completely drained, making it easier for the staff to disassemble the U-shaped glass tube.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. During the cultivation of Chlorella, the Chlorella will flow through six groups of U-shaped glass tubes in sequence with the mixed liquid, and the U-shaped glass tubes are all exposed to light. The Chlorella is dispersed in the six groups of U-shaped glass tubes, which not only increases the contact area between the Chlorella and the light, but also makes the Chlorella receive light more evenly, thereby increasing the photosynthetic rate of the Chlorella and thus accelerating the overall reproduction rate of the Chlorella.

[0014] 2. Rotate the U-shaped glass tube in the direction opposite to the plant growth lamp. The U-shaped glass tube drives the rotary tube together with the sealing rubber sleeve and other components to rotate around the main tube. As the U-shaped glass tube rotates, the end of the U-shaped glass tube will face downward. Under the action of gravity, the mixed liquid in the U-shaped glass tube will flow back into the rotary tube through the rotary nozzle, and the refluxed mixed liquid will flow back into the incubator through the main tube and other U-shaped glass tubes. Since the end of the U-shaped glass tube faces downward, on the one hand, the mixed liquid in the U-shaped glass tube can be directly discharged, thereby improving the cleaning efficiency of the U-shaped glass tube. On the other hand, the mixed liquid flowing in the main tube cannot enter the U-shaped glass tube. The flowing mixed liquid will flow directly through the rotary tube into the next set of rotary tubes, so that the illumination of Chlorella can be carried out normally, thereby ensuring the illumination rate of Chlorella.

[0015] 3. During the disassembly of the U-shaped glass tube, the short teeth will limit the claws that move back. When the staff loses control, the U-shaped glass tube cannot rotate back, thereby avoiding the collision between the U-shaped glass tube and the plant growth lamp. Secondly, since the short teeth limit the claws, the staff does not need to hold the U-shaped glass tube all the time while waiting for the mixed liquid in the U-shaped glass tube to be completely drained, making it easier for the staff to disassemble the U-shaped glass tube.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Embodiment 1

[0027] like Figure 1 and Figure 2 As shown, a Chlorella cultivation device described in an embodiment of the present invention includes a cultivation box 1, an air inlet pipe 2 and a water outlet pipe 3 are arranged in the cultivation box 1, and a feed nozzle 6 is arranged on one side of the cultivation box 1, one end of the water outlet pipe 3 is connected to the water inlet end of the water pump 4, and the water outlet end of the water pump 4 is connected to the circulating lighting mechanism 5, and the circulating lighting mechanism 5 includes a support frame 501, one end of the support frame 501 is fixedly connected to the cultivation box 1, a U-shaped pipe 502 fixedly installed on the support frame 501, six groups of U-shaped glass tubes 503 fixedly installed on the U-shaped pipe 502, the interior of the U-shaped glass tube 503 is connected to the interior of the U-shaped pipe 502, one end of the U-shaped pipe 502 is connected to the water outlet end of the water pump 4, and the other end of the U-shaped pipe 502 extends into the cultivation box 1, and three groups of plant growth lamps 504 are arranged between the six groups of U-shaped glass tubes 503, and the plant growth lamps 504 are fixedly installed on the support frame 501.

[0028] Specifically, the air inlet pipe 2 is connected to the oxygen supply device, and the U-shaped glass tube 503 is made of transparent glass. When it is necessary to cultivate Chlorella, a mixture of Chlorella, water, and nutrient solution is injected into the cultivation box 1 through the feed nozzle 6. It should be noted that the liquid level of the mixed liquid in the cultivation box 1 must eventually be lower than the other end of the U-shaped pipe 502. Then, the plant growth lamp 504 is powered on, and oxygen is blown into the mixed liquid through the air inlet pipe 2 through the oxygen supply device. Then, the water pump 4 is started. The water pump 4 slowly draws the mixed liquid in the cultivation box 1 into the U-shaped pipe 502 through the outlet pipe 3. As the mixed liquid enters the U-shaped pipe 502, the mixed liquid will flow into the U-shaped glass tube 503. After the U-shaped glass tube 503 is filled with the mixed liquid, the mixed liquid overflows from the end of the U-shaped glass tube 503, and the overflowed mixed liquid flows through the U-shaped pipe 502. The mixed liquid flows into the next group of U-shaped glass tubes 503 until the remaining U-shaped glass tubes 503 are filled with the mixed liquid. The mixed liquid finally flows back to the cultivation box 1 through the other end of the U-shaped pipe 502. During the flow of the mixed liquid in the U-shaped glass tubes 503, the light emitted by the plant growth lamp 504 shines on the U-shaped glass tubes 503, so that the Chlorella flowing in the U-shaped glass tubes 503 is illuminated, thereby realizing the cultivation of Chlorella. Compared with the prior art, during the cultivation of Chlorella, the Chlorella will flow through the six groups of U-shaped glass tubes 503 in sequence with the mixed liquid, and the U-shaped glass tubes 503 are all illuminated. The Chlorella is dispersed in the six groups of U-shaped glass tubes 503, which not only increases the contact area between the Chlorella and the light, but also makes the Chlorella receive the light more evenly, thereby improving the photosynthetic rate of the Chlorella, thereby accelerating the overall reproduction rate of the Chlorella.

[0029] like Figure 3 and Figure 4 As shown, the U-shaped pipe 502 includes a main pipe 5021, which is fixedly mounted on the support frame 501, six sets of rotary pipes 5022 rotatably mounted on the main pipe 5021, two sets of rotary nozzles 5023 symmetrically arranged on the rotary pipe 5022, an arc partition 5024 fixedly mounted in the main pipe 5021, and two sets of sealing rubber sleeves 5026 symmetrically fixedly mounted in the rotary pipe 5022. One end of the main pipe 5021 is connected to the water outlet end of the water pump 4, and the main pipe 5021 is connected to the water outlet end of the water pump 4. The other end of the U-shaped glass tube 503 extends into the incubator 1, the inner circle of the arc partition 5024 fits the outer circle of the main tube 5021, the main tube 5021 passes through the sealing rubber sleeve 5026, and the inner circle of the sealing rubber sleeve 5026 fits the outer circle of the main tube 5021, the main tube 5021 is provided with a plurality of groups of openings 211, the screw nozzle 5023 is located directly below the opening 211, and the end of the U-shaped glass tube 503 is movably sleeved with a screw sleeve 5031, which is used for screwing the screw nozzle 5023.

[0030] Specifically, after long-term use, the inner wall of the U-shaped glass tube 503 will be attached with chlorella and other dirt, resulting in poor light transmittance of the U-shaped glass tube 503. Therefore, the U-shaped glass tube 503 needs to be disassembled for cleaning. Once one set of the U-shaped glass tubes 503 needs to be disassembled, the operation of the water pump 4 must be stopped, which makes the light rate of the chlorella suddenly become very poor, affecting the reproduction rate. Secondly, after the U-shaped glass tube 503 is disassembled, there will be a mixed liquid in the U-shaped glass tube 503. The U-shaped glass tube 503 needs to be cleaned first. 3 is poured back into the incubator 1 to clean the U-shaped glass tube 503, which affects the cleaning efficiency of the U-shaped glass tube 503. When the mixed liquid enters the U-shaped pipe 502, the mixed liquid will flow into the main pipe 5021 and flow into the screw pipe 5022 through the opening 211 on the main pipe 5021. Then, it is injected into the U-shaped glass tube 503 through a set of screw nozzles 5023 on the screw pipe 5022. When one set of U-shaped glass tubes 503 needs to be cleaned, the U-shaped glass tube 503 is rotated with its back facing the direction of the plant growth lamp 504. The U-shaped glass tube 503 drives the screw tube 5022 together with the sealing rubber sleeve 5026 and other components to rotate around the main pipe 5021. As the U-shaped glass tube 503 rotates, the end of the U-shaped glass tube 503 will face downward. Under the action of gravity, the mixed liquid in the U-shaped glass tube 503 will flow back into the screw tube 5022 through the screw nozzle 5023, and the refluxed mixed liquid will flow back into the incubator 1 through the main pipe 5021 and other U-shaped glass tubes 503. After the mixed liquid in the U-shaped glass tube 503 is discharged, the screw sleeve 5031 is screwed to release the mixed liquid. In addition to fixing the U-shaped glass tube 503 and the screw-on tube 5022, the U-shaped glass tube 503 is disassembled for cleaning. Since the end of the U-shaped glass tube 503 faces downward, on the one hand, the mixed liquid in the U-shaped glass tube 503 can be directly discharged, thereby improving the cleaning efficiency of the U-shaped glass tube 503. On the other hand, the mixed liquid flowing in the main tube 5021 cannot enter the U-shaped glass tube 503. The flowing mixed liquid will directly pass through the screw-on tube 5022 and flow into the next group of screw-on tubes 5022, thereby allowing the illumination of the Chlorella to proceed normally and ensuring the illumination rate of the Chlorella.

[0031] Embodiment 2

[0032] like Figure 6 and Figure 7As shown, compared with Example 1, another implementation of the present invention is that: both ends of the rotating tube 5022 are provided with a limiting mechanism 5025, the limiting mechanism 5025 includes a fixed sleeve 251, the fixed sleeve 251 is fixedly sleeved on the main tube 5021, a plurality of groups of bevel teeth 252 arranged at equal angles on the outer ring of the fixed sleeve 251, a claw 253 clamping the bevel teeth 252, a flap 254, one end of the claw 253 clamps the bevel teeth 252, the bevel teeth 252 are composed of a plurality of groups of short teeth 21 and a group of long teeth 22, the other end of the claw 253 is fixedly connected to the flap 254, a first U-shaped elastic strip 255 arranged on one side of the claw 253, a limiting plate 256 for limiting the flap 254, and a The second U-shaped elastic bar 257 arranged on one side of the limit plate 256 is used to push the unlocking rod 258 of the limit plate 256, and the sealing plate 259 is fixedly connected to the unlocking rod 258. The claw 253 and the limit plate 256 are both hinged to the inner wall of the rotary tube 5022. The first U-shaped elastic bar 255 and the second U-shaped elastic bar 257 are both fixedly installed in the end of the rotary tube 5022. The end of the limit plate 256 is provided with a slope 61. The fixing sleeve 251 of the sealing plate 259 is installed on the main pipe 5021, and the sealing plate 259 fits the end surface of the rotary tube 5022. The fixing sleeve 251 is provided with an arc groove 91, and the arc groove 91 is slidably connected to the limit rod 92, and the limit rod 92 is fixedly connected to the rotary tube 5022.

[0033] Specifically, the weight of the U-shaped glass tube 503 increases significantly after the mixed liquid is injected into it. During the process of rotating the U-shaped glass tube 503, if the worker loses control and causes the U-shaped glass tube 503 to fall out of his hand, the U-shaped glass tube 503 rotating back will directly hit the plant growth lamp 504, causing damage to the U-shaped glass tube 503 and the plant growth lamp 504. Secondly, after the U-shaped glass tube 503 is rotated to the end facing downward, the worker needs to wait for the mixed liquid in the U-shaped glass tube 503 to be completely drained, resulting in the worker having to hold the U-shaped glass tube 503 all the time. Therefore, before rotating the U-shaped glass tube 503, the end of the unlocking rod 258 abuts against the limit plate 256, so that the limit plate 256 is in an inclined state, and the second U-shaped elastic bar 257 is affected by the limit plate 2 56 is compressed. When the U-shaped glass tube 503 is rotated, the rotating tube 5022 drives the claw 253, the flap 254, the limit plate 256, the limit rod 92 and other components to rotate around the fixed sleeve 251. The unlocking rod 258 will release the compression of the limit plate 256. Under the rebound force of the second U-shaped elastic bar 257, the limit plate 256 is returned to the normal position. During the rotation process, the limit rod 92 slides along the arc groove 91 on the fixed sleeve 251. At the same time, one end of the claw 253 will be continuously squeezed by the several groups of short teeth 21 on the fixed sleeve 251, so that the claw 253 rotates toward the first U-shaped elastic bar 255 and repeatedly compresses the first U-shaped elastic bar 255 until one end of the claw 253 is located at the long teeth 22 on the fixed sleeve 251. When one end of the clamping claw 253 is squeezed by the short teeth 21, the clamping claw 253 drives the flap 254 to move toward the limiting plate 256, and the end of the flap 254 cannot squeeze the inclined surface 61 at the end of the limiting plate 256. After the clean U-shaped glass tube 503 is installed on the rotating tube 5022, the clean U-shaped glass tube 503 continues to be rotated toward the plant growth lamp 504. At this time, one end of the clamping claw 253 will rotate against the long teeth 22. The clamping claw 253 is squeezed by the long teeth 22 and the rotation amplitude will increase, causing the end of the flap 254 to be squeezed to the inclined surface 61 at the end of the limiting plate 256. The second U-shaped elastic bar 257 is compressed again until the end of the flap 254 is offset from the inclined surface 61. Under the action of the rebound force of the second U-shaped elastic bar 257, the limiting plate 256 blocks the flap. 254, so that the claw 253 is limited. At this time, the clean U-shaped glass tube 503 is rotated downward until the clean U-shaped glass tube 503 is located directly below the rotating tube 5022. During the downward rotation, the limit plate 256 is pushed by the unlocking rod 258, thereby releasing the limit plate 256 from blocking the flap 254. Under the rebound force of the first U-shaped elastic bar 255, the claw 253 is clamped with the short tooth 21 again. During the removal of the U-shaped glass tube 503, the short tooth 21 will limit the claw 253 moving back. When the staff loses control, the U-shaped glass tube 503 cannot be rotated back, thereby preventing the U-shaped glass tube 503 from colliding with the plant growth lamp 504. Secondly, since the short tooth 21 limits the claw 253,While waiting for the mixed liquid in the U-shaped glass tube 503 to be completely drained, the worker does not need to hold the U-shaped glass tube 503 all the time, making it easier for the worker to disassemble the U-shaped glass tube 503.

[0034] Working principle: a mixture of chlorella, water and nutrient solution is injected into the cultivation box 1 through the feed nozzle 6, and then the plant growth lamp 504 is powered on, and oxygen is blown into the mixture through the air inlet pipe 2 through the oxygen supply device, and then the water pump 4 is started, and the water pump 4 slowly pumps the mixture in the cultivation box 1 into the U-shaped pipe 502 through the outlet pipe 3. As the mixed liquid enters the U-shaped pipe 502, the mixed liquid will flow into the U-shaped glass tube 503. After the U-shaped glass tube 503 is filled with the mixed liquid, the mixed liquid The mixed liquid overflows from the end of the U-shaped glass tube 503, and the overflowed mixed liquid flows into the next group of U-shaped glass tubes 503 through the U-shaped pipe 502 until the remaining U-shaped glass tubes 503 are filled with the mixed liquid, and the mixed liquid finally flows back into the cultivation box 1 through the other end of the U-shaped pipe 502. During the flow of the mixed liquid in the U-shaped glass tube 503, the light emitted by the plant growth lamp 504 irradiates the U-shaped glass tube 503, so that the Chlorella flowing in the U-shaped glass tube 503 is illuminated, thereby realizing the cultivation of Chlorella;

[0035] When it is necessary to clean one of the groups of U-shaped glass tubes 503, the U-shaped glass tube 503 is rotated in the direction of the plant growth lamp 504, and the U-shaped glass tube 503 drives the screw tube 5022 together with the sealing rubber sleeve 5026 and other components to rotate around the main pipe 5021. As the U-shaped glass tube 503 rotates, the end of the U-shaped glass tube 503 will face downward. Under the action of gravity, the mixed liquid in the U-shaped glass tube 503 will flow back into the screw tube 5022 through the screw nozzle 5023, and the refluxed mixed liquid will flow back into the incubator 1 through the main pipe 5021 and other U-shaped glass tubes 503. After the mixed liquid in the U-shaped glass tube 503 is discharged, the screw sleeve 5031 is screwed to release the fixation between the U-shaped glass tube 503 and the screw tube 5022, and the U-shaped glass tube 503 is disassembled for cleaning;

[0036] Before the U-shaped glass tube 503 is rotated, the end of the unlocking rod 258 abuts against the limit plate 256, so that the limit plate 256 is in an inclined state, and the second U-shaped elastic bar 257 is compressed by the limit plate 256. When the U-shaped glass tube 503 is rotated, the rotating tube 5022 drives the claw 253, the flap 254, the limit plate 256, the limit rod 92 and other components to rotate around the fixed sleeve 251, and the unlocking rod 258 releases the squeeze on the limit plate 256. Under the rebound force of the second U-shaped elastic bar 257, the limit plate 256 is During the rotation, the limit rod 92 slides along the arc groove 91 on the fixed sleeve 251, and at the same time, one end of the claw 253 is continuously squeezed by the several groups of short teeth 21 on the fixed sleeve 251, so that the claw 253 rotates toward the first U-shaped elastic bar 255 and repeatedly compresses the first U-shaped elastic bar 255 until one end of the claw 253 is located at the long teeth 22 on the fixed sleeve 251. When one end of the claw 253 is squeezed by the short teeth 21, the claw 253 drives the flap 254 to move toward the limit plate 256, and the flap 254 is rotated toward the first U-shaped elastic bar 255. The end of the plate 254 cannot be squeezed to the inclined surface 61 of the end of the limiting plate 256. After the clean U-shaped glass tube 503 is installed on the rotating tube 5022, the clean U-shaped glass tube 503 continues to be rotated toward the plant growth lamp 504. At this time, one end of the claw 253 will rotate close to the long teeth 22. The claw 253 is squeezed by the long teeth 22 and the rotation amplitude will increase, causing the end of the flap 254 to be squeezed to the inclined surface 61 of the end of the limiting plate 256. The second U-shaped elastic strip 257 is compressed again until the end of the flap 254 is offset. The inclined surface 61 is opened, and under the rebound force of the second U-shaped elastic bar 257, the limit plate 256 blocks the flap 254, so that the claw 253 is limited. At this time, the clean U-shaped glass tube 503 is rotated downward until the clean U-shaped glass tube 503 is located directly below the rotating tube 5022. During the downward rotation process, the limit plate 256 is pushed by the unlocking rod 258, thereby releasing the blockage of the limit plate 256 on the flap 254. Under the rebound force of the first U-shaped elastic bar 255, the claw 253 is clamped with the short tooth 21 again.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention.
