A disinfection device for a Haematococcus pluvialis culture system

Abstract

The present invention relates to the technical field of Haematococcus pluvialis cultivation, and specifically relates to a disinfection device for a Haematococcus pluvialis cultivation system, which includes an algae storage tank, a disinfection tank, and a number of cultivation tubes. A separation part is connected and arranged between two adjacent upper and lower ones among a number of cultivation tubes on the same side. By starting the double-headed motor to drive the partition to rotate 90 degrees, a number of liquid passing boxes and connecting tubes are blocked, so as to cut off two adjacent cultivation tubes at the same height, and at the same time, the two adjacent upper and lower cultivation tubes are connected to form a loop path. Then, the disinfectant with a large density sinks into the lower cultivation tube to form a layer, and it can be pumped and drained, while the Haematococcus pluvialis culture solution is retained in the cultivation tube for continuous cultivation. Then, just open the liquid outlet pipe to release the disinfectant. Therefore, it is not necessary to lead out and collect all the Haematococcus pluvialis culture solution and then separate the disinfectant. This device saves the time and process of disinfection and separation, and avoids the long-term adverse effects of the disinfectant on the Haematococcus pluvialis culture solution.

[0039] Please refer to Figures 1 - 11As shown in the figure, the present invention provides a disinfection device for a Haematococcus pluvialis culture system, which includes an algae storage tank 100, a disinfection tank 130, and a number of branch pipe racks 110 arranged side by side at equal intervals on one side of the liquid infusion end of the algae storage tank 100. A pump is provided on the algae storage tank 100 to pump Haematococcus pluvialis into a number of culture pipes 120 for receiving light and growing; a pump is provided on the disinfection tank 130 to pump the disinfectant solution into a number of culture pipes 120 for disinfection treatment. By increasing the proportion of the solute in the disinfectant solution, its density is made greater than the density of the Haematococcus pluvialis culture solution, and then natural sedimentation and stratification occur subsequently, so as to be sucked and discharged. Furthermore, it is not necessary to lead out and collect all the Haematococcus pluvialis culture solution and then separate the disinfectant solution. This device saves the time and procedures of disinfection and separation, and avoids the long-term adverse effects of the disinfectant solution on the Haematococcus pluvialis culture solution;

[0040] The branch pipe rack 110 extends vertically, and a number of culture pipes 120 are placed at equal intervals on both its front and back sides. On both the front and back sides of each branch pipe rack 110, there is a separation part 200 that connects the upper and lower adjacent ones among the several culture pipes 120 on the same side; on both the front and back sides of the branch pipe rack 110, a number of brackets 111 are symmetrically welded. The ends of the culture pipes 120 are lapped on a pair of brackets 111 at the same height, making the culture pipes 120 stably placed and facilitating coaxial docking installation for the circulation of the Haematococcus pluvialis culture solution.

[0041] Specifically, two pairs of adjacent upper and lower culture pipes 120 placed on one side of the branch pipe rack 110 are taken as a group. The separation part 200 includes a number of liquid connection boxes 210 sleeved with each group of two pairs of adjacent upper and lower culture pipes 120, a liquid separation group 220 arranged in the liquid connection box 210 and used to adjust the communication path between the two pairs of adjacent upper and lower culture pipes 120, and a double-headed motor 230 used to drive the on-off states of a number of liquid separation groups 220; the liquid connection box 210 is composed of an open circular box and connection pipes 211 symmetrically arranged on its outer side. The connection pipes 211 are perpendicular to the central axis of the circular box, and a connection cover 2111 is integrally formed between the connection pipes 211 and the circular box to form a connected state;

[0042] That is, when culturing Haematococcus pluvialis, the liquid separation group 220 does not block the connection pipes 211 to ensure the communication of several culture pipes 120 at the same height and the flow of the Haematococcus pluvialis culture solution; after the disinfectant solution is pumped in, by starting the double-headed motor 230 to drive a number of liquid separation groups 220 to block a number of liquid connection boxes 210 and connection pipes 211, the two adjacent culture pipes 120 at the same height are thus separated, and at the same time, the two adjacent upper and lower culture pipes 120 are connected to form a loop path. The disinfectant solution with a large density sinks into the lower culture pipe 120 to form a layer, and it can be pumped and discharged while retaining the Haematococcus pluvialis culture solution in the culture pipe 120 for continuous cultivation.

[0043] Specifically, the liquid barrier assembly 220 includes a diaphragm 221 adapted to be matched with the connecting tube 211 and capable of rotating, a rotating column 222 disposed in the connecting cover 2111 and plugged into the side wall of the diaphragm 221, and a linkage frame 223 coaxially connected to the round box and driving the rotating column 222 to rotate.

[0044] The opening of the liquid-passing box 210 is tightly clamped with the box cover 212, and the linkage frame 223 is coaxially connected to the pulley 224 toward the center of the outer end. The output shaft end of the double-headed motor 230 is sleeved with a toothed belt 231, and the toothed belt 231 is meshed and sleeved with several pulleys 224 located in a vertical row on the same side; the double-headed motor 230 drives the toothed belt 231 to circulate, thereby driving the several pulleys 224 to rotate, and then driving the linkage frame 223 to rotate 90 degrees. The linkage frame 223 triggers the rotating column 222 to drive the spacer 221 to rotate 90 degrees, thereby switching the blocked and unobstructed states in the connecting pipe 211; the double-headed motor 230 is fixedly connected to the inner side of the bottom of the support pipe frame 110 by bolts, and the bottom side wall of the support pipe frame 110 is provided with a through hole 113 for the output shaft of the double-headed motor 230 to pass through and rotate stably;

[0045] A square recessed hole 2233 is formed outside the central axis of the linkage frame 223 , and a plug rod 2241 is sleeved on the central hole of the pulley 224 to engage with the recessed hole 2233 , so that the pulley 224 and the linkage frame 223 move synchronously.

[0046] Furthermore, sealing pieces 225 coaxially connected to the rotating column 222 are provided on the upper and lower inner walls of the circular box of the liquid-passing box 210. The size of the sealing piece 225 is larger than that of the connecting cover 2111, and the width direction of the sealing piece 225 is consistent with the axial direction of the septum 221. When the axial direction of the septum 221 is perpendicular to the axial direction of the connecting tube 211, the sealing piece 225 blocks the communication port between the connecting cover 2111 and the liquid-passing box 210. When the axial direction of the septum 221 is coaxial with the axial direction of the connecting tube 211, the sealing piece 225 rotates and is arranged perpendicular to the connecting cover 2111, so that the two ends of the upper and lower adjacent culture tubes 120 are connected to the convection layer through the liquid-passing box 210.

[0047] When not disinfecting, the partition group 220 is in an open state, and the two adjacent culture tubes 120 at the same height are connected to circulate the Haematococcus algae culture solution; when disinfecting, the partition group 220 is in a partitioned state, and the upper and lower adjacent culture tubes 120 are connected to circulate the Haematococcus algae culture solution and disinfectant. Due to its high density, the disinfectant precipitates into the culture tube 120 located below, forming a separation state of the Haematococcus algae culture solution and the disinfectant; wherein, the bottom of the culture tube 120 connected to the connecting tube 211 below is provided with a liquid outlet pipe 121 for draining the disinfectant.

[0048] Furthermore, a pair of algae discharge pipes 101 are connected to one side of the algae storage tank 100. A pipe sleeve sleeving a number of aquaculture pipes 120 is connected to the side wall of the algae discharge pipe 101. A pair of liquid discharge pipes 131 inserted into the tops of the pair of algae discharge pipes 101 are connected and inserted into the top of the disinfection tank 130. A water valve is arranged at the connection between the liquid discharge pipe 131 and the algae discharge pipe 101 to control the flow of the disinfection liquid into the algae discharge pipe 101 and then into the aquaculture pipe 120 for disinfection.

[0049] Specifically, a support ring 2112 is integrally formed in the middle of the inner cavity of the connection cover 2111. The rotating column 222 is sleeved and matched with the support ring 2112, and a number of sealing rings are embedded on the outer side of the rotating column 222 to ensure that the liquid does not leak here. A driving tooth column 2221 is tightly inserted into the circular box end of the rotating column 222 facing the liquid passing box 210. Card slots 2231 are opened at both ends of the linkage frame 223 facing the inner wall of the circular box. A number of convex teeth 2232 are arranged on one side wall of the card slot 2231. The number of convex teeth 2232 is meshed with one-fourth of a turn of the driving tooth column 2221. That is, when the linkage frame 223 rotates to the vertical position, it touches the rotating column 222 to drive the partition 221 to rotate 90 degrees, and switches between the closed and unblocked states of the connection pipe 211.

[0050] A square column 2222 is inserted into the central hole of the driving tooth column 2221. The sealing piece 225 is made of spring steel into an arched straight sheet, and a square hole 2251 is opened in the center thereof. The square hole 2251 is sleeved and matched with the column 2222, so that the sealing piece 225 rotates synchronously with the driving tooth column 2221, and switches the position where it fits with the connection cover 2111. Both sides of the central axis of the linkage frame 223 extend to the rear wall of the liquid passing box 210 and the inner wall of the box cover 212, and sealing gaskets 213 are bonded to the rear wall of the liquid passing box 210 and the inner wall of the box cover 212. Both ends of the linkage frame 223 facing the inner wall of the circular box are arc-shaped and are in sliding contact with the sealing piece 225.

[0051] Since the sealing piece 225 has elasticity, and silica gel pads are bonded to its upper and lower surfaces for sealing, when the linkage frame 223 rotates, it can fit and squeeze the sealing piece 225 to fit the liquid passing box 210, ensuring that the liquid passing box 210 is separated into two cavities to circulate the solution respectively.

[0052] In addition, in order to recycle the disinfection liquid, a recovery part 300 for siphoning the disinfection liquid in the aquaculture pipe 120 is arranged between every two adjacent branch pipe racks 110. The recovery part 300 includes two vertical columns of a number of liquid guiding pipes 310 connected end to end and an electromagnetic valve 320 connected and installed to the liquid outlet pipe 121 and the liquid guiding pipe 310. The opening and closing of the electromagnetic valve 320 control the on-off of the liquid outlet pipe 121. The length of the liquid guiding pipe 310 is the distance between two aquaculture pipes 120. The upper end of the electromagnetic valve 320 is sleeved and matched with the liquid outlet pipe 121. A communicating pipe 311 is embedded in the side wall of the top of the liquid guiding pipe 310, and the communicating pipe 311 is connected to the lower end of the electromagnetic valve 320 through a bent pipe.

[0053] Further, a recovery pipe 330 is symmetrically laid below several support pipe racks 110. One end of the recovery pipe 330 is closed, and a siphon pipe 332 is vertically sleeved on the other end. Return liquid pipes 132 are symmetrically embedded in the top side wall of the disinfection tank 130, and the top end of the siphon pipe 332 is in socket fit with the return liquid pipes 132; A connecting pipe 331 is embedded in the top of the horizontal section of the recovery pipe 330 and below the liquid guiding pipe 310. The lowermost liquid guiding pipe 310 is in corresponding socket fit with the connecting pipe 331, and a pipe cap 340 is sleeved on the top end of the uppermost liquid guiding pipe 310 to play a sealing role;

[0054] After the disinfectant liquid is stratified, the solenoid valve 320 is started to connect the liquid outlet pipe 121 and the liquid guiding pipe 310. The disinfectant liquid falls into the recovery pipe 330 until the siphon pipe 332 is filled, and then flows into the disinfection tank 130 to form a siphon until the disinfectant liquid in the culture pipe 120 is drained, and then the solenoid valve 320 can be closed.

[0055] Further, a ferrule 312 is fixedly arranged on the side wall of the liquid guiding pipe 310. The ferrule 312 is of a C-shaped structure and is in snap fit with the culture pipe 120, so that the liquid guiding pipe 310 is convenient to disassemble and assemble; A pair of support rods 112 are welded between the bottoms of two adjacent support pipe racks 110. The lowermost liquid guiding pipe 310 is fixed by being in snap fit with the middle part of the support rod 112 through the ferrule 312.

[0056] When the disinfection device of the Haematococcus pluvialis culture system of the present invention disinfects, the disinfectant liquid is pumped into several culture pipes 120 by the pump on the disinfection tank 130, and then left standing for a period of time for disinfection. Then, the double-headed motor 230 is started to drive the toothed belt 231 to move in a cycle, which drives several belt wheels 224 to rotate, and then drives the linkage frame 223 to rotate 90 degrees. The linkage frame 223 touches the rotating column 222 to drive the partition 221 to rotate 90 degrees, thereby blocking several liquid passing boxes 210 and the connecting pipes 211, so as to cut off two adjacent culture pipes 120 at the same height, and at the same time connect two adjacent upper and lower culture pipes 120 to form a loop path. Then, the disinfectant liquid with a large density sinks into the lower culture pipe 120 to form a layer, and it can be pumped and drained to retain the Haematococcus pluvialis culture solution in the culture pipe 120 for continuous culture;

[0057] After the disinfectant liquid is stratified, the solenoid valve 320 is started to connect the liquid outlet pipe 121 and the liquid guiding pipe 310. The disinfectant liquid falls into the recovery pipe 330 until the siphon pipe 332 is filled, and then flows into the disinfection tank 130 to form a siphon until the disinfectant liquid in the culture pipe 120 is drained, and then the solenoid valve 320 can be closed; Furthermore, it is not necessary to lead out all the Haematococcus pluvialis culture solution for collection and then separate the disinfectant liquid. This device saves the time and process of disinfection and separation, and avoids the long-term adverse effects of the disinfectant liquid on the Haematococcus pluvialis culture solution.
