Description

Technical Field

[0001] The invention relates to the field of bacterial agent amplification, and in particular to a bacterial agent amplification and automatic delivery device for sewage treatment. Background Art

[0002] With the continuous development of modern industry, the concentration of ammonia nitrogen in various industrial wastewater is very high. A large amount of untreated or improperly treated wastewater containing high ammonia nitrogen is discharged into the environment, causing water quality to deteriorate and even lake degradation. With the in-depth research of scientific researchers, various high-efficiency microbial preparations have been widely used in the treatment of high ammonia nitrogen wastewater.

[0003] The effect of microbial agents lasts for a short time after being added and used, and new agents need to be continuously added during the wastewater treatment process to maintain the effect they produce. At present, bacterial culture generally adopts solid culture medium, liquid culture medium, and bacterial fermentation tank. Some invention patents related to liquid culture medium amplification are disclosed in the prior art. The Chinese patent with publication number CN202116383U discloses a device for cultivating and amplifying high-efficiency solid microbial agents, including an inlet pipe, an outlet pipe, a tank body, a stirring device, an aeration device, a mud hopper and a mud discharge pipe. The inlet pipe is arranged at the top of the side wall of the tank body, and the outlet pipe is arranged at the bottom of the side wall of the tank body. The stirring device includes a power device, a transmission rod and a paddle. The transmission rod connects the power device and the paddle. The mud hopper is arranged at the bottom of the tank body and connected to the mud discharge pipe. The aeration device is arranged at the bottom of the tank body. Amplification of high-efficiency solid bacterial agents is achieved, and new supplementary bacterial liquid is continuously provided for the treatment of high-ammonia nitrogen wastewater.

[0004] However, during the amplification process, the existing solid microbial inoculant culture and amplification devices mainly rely on the space's own illumination or a fixed lamp head to provide a light source. It is not convenient to adjust the light source according to the height of the bacterial liquid level in the amplification tank, which easily causes a large difference in the intensity of the light source received by the bacterial liquid, affecting the amplification efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a device for amplifying and automatically delivering bacterial agents for sewage treatment.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: a sewage treatment bacterial agent amplification and automatic delivery device, including an amplification tank and a cover body, and also including

[0007] An illumination assembly, the illumination assembly comprising an annular seat, a plurality of lamp caps mounted on the annular seat, a rotation adjustment unit for driving the annular seat to rotate, and a height adjustment unit for adjusting the height of the annular seat, so as to adjust the distance between the rotating lamp cap and the liquid surface, and after the distance is adjusted, the annular seat is rotated to drive the lamp caps to move in a circular trajectory;

[0008] A spacing identification component is used to detect and identify the spacing between the annular seat and the liquid surface;

[0009] The bacterial liquid release solenoid valve is fixedly connected to the bottom end of the right side of the amplification tank to release the amplified bacterial liquid when needed.

[0010] It should be understood that after the solid microbial agent is put into the amplification tank, the cover is put on. Before adding the solid microbial agent, the annular seat and the lamp head of the illumination assembly are adjusted to the top of the inside of the amplification tank. After adding the solid microbial agent, water is passed into the amplification tank. When the liquid level rises to the set height, the water supply is stopped. Then, the height of the annular seat is adjusted through the height adjustment unit according to the distance between the annular seat and the liquid surface detected by the distance recognition assembly, that is, the heights of multiple lamp heads are adjusted synchronously, so that the mixed liquid of the solid microbial agent and water is close to the light source, and in the process of culture and amplification, the annular seat is continuously driven to rotate by the rotating adjustment unit, thereby driving the lamp head to move along a circular trajectory, so as to achieve uniform irradiation of the mixed liquid of the solid microbial agent and water. On the one hand, the stability of the light source is ensured, and on the other hand, it is conducive to uniform illumination and to improving amplification efficiency.

[0011] Specifically, it also includes a probe, which is arranged through the top right side of the amplification tank and is used to monitor the inside of the amplification tank.

[0012] The specific probe is a temperature detection unit, which is used to stably detect and observe the temperature in the amplification tank.

[0013] Specifically, it also includes an aeration member, which is arranged at the left bottom end and extends to the interior of the amplification tank after penetrating the amplification tank, and has aeration holes.

[0014] It should be understood that by providing an aeration element, aerobic bacteria need to supply oxygen to the mixture of solid microbial agent and water in the amplification tank to maintain sufficient oxygen and provide conditions for the aerobic bacteria to expand.

[0015] Specifically, it also includes a heating element, which is fixedly installed at the bottom end of the amplification tank and is used to heat the liquid in the amplification tank.

[0016] It should be understood that by providing a heating element and coordinating with the temperature detected by the probe, heating control can be performed to try to maintain a temperature inside the amplification tank that is conducive to bacterial amplification.

[0017] As an optional technical solution of the present invention, it also includes a connecting ring, which is fixedly connected to the side wall of the annular seat, and the annular cover is fixedly connected to the outer side wall of the amplification tank. There are four height adjustment components, and the height adjustment components include

[0018] A clearance groove, wherein the clearance groove is provided on the side of the amplification tank;

[0019] A moving seat, the moving seat being slidably connected to the surface of the connecting ring;

[0020] A threaded rod is threadedly connected to the moving seat, and a first motor is fixedly connected to the bottom end thereof, and the first motor is fixedly installed in the annular cover.

[0021] It should be understood that when the height of the annular seat and the lamp head needs to be adjusted, multiple first motors are started at the same time, the first motors drive the threaded rod to rotate, the threaded rod threads drive the moving seat to lower the height, the moving seat drives the connecting ring to move, and the connecting ring synchronously drives the annular seat to move, thereby realizing the height adjustment of the lamp head installed on the annular seat.

[0022] As an optional technical solution of the present invention, the rotation drive unit includes

[0023] an annular rack, the annular rack being fixedly connected to the connecting ring;

[0024] The second motor is fixedly connected to the moving base, and the output end of the second motor is fixedly connected to a driving gear meshing with the annular rack.

[0025] It should be understood that when the lamp head needs to be moved, the second motor is started, the second motor drives the driving gear to rotate, the driving gear transmits the annular rack, the annular rack drives the connecting ring to rotate, and the connecting ring synchronously drives the annular seat to rotate, thereby driving the lamp head on the annular seat to move in a circular trajectory.

[0026] It should be further explained that, by installing the rotary drive unit on the movable seat, it is advantageous to synchronously adjust the rotary drive unit according to the adjustment of the height of the annular seat, thereby avoiding obstacles.

[0027] As a further optimized technical solution of the present invention, it also includes

[0028] A plurality of mounting grooves, wherein the plurality of mounting grooves are arranged in an annular array on the side wall of the annular seat, and the plurality of lamp holders are rotatably mounted in the plurality of mounting grooves respectively;

[0029] A plurality of angle adjustment components are used for adjusting the angles of a plurality of lamp heads when the annular seat moves downward to an ideal height.

[0030] It should be understood that adjusting the angle of the lamp head by the angle adjustment component is conducive to directing the illumination direction of the lamp head toward the liquid surface, so that the light source can illuminate the liquid surface of the mixed liquid as much as possible, which is conducive to maximizing the use of the light source.

[0031] As an optional technical solution of the present invention, the angle adjustment component includes

[0032] A linkage pin, wherein the linkage pin is fixedly connected to the surface of the lamp holder at a corresponding position;

[0033] A linkage frame, wherein the linkage frame is slidably sleeved on the surface of the linkage pin, and the bottom is fixedly connected to the bottom end of the inner wall of the installation groove through a gas spring;

[0034] The top of the linkage frame is fixedly connected with a linkage rod, and the top of the linkage rod passes through the annular seat and extends to the top of the annular seat;

[0035] A limiting ring is fixedly connected to the inner wall of the amplification tank and is in contact with the top end of the linkage rod below.

[0036] It should be understood that since there are multiple lamp heads, there is a state limitation in the process of adjusting the angle. When the annular seat moves to the top of the amplification tank, it is in the feeding state. The top of the linkage rod will be limited by the limiting ring. The linkage rod limits the position of the linkage pin through the linkage frame, thereby keeping the lamp head stored in the installation groove, avoiding interference with the feeding on the one hand, and preventing the added material from contaminating the lamp head on the other hand;

[0037] After the addition is completed, the height adjustment unit is used to adjust the annular seat and the lamp head as a whole to be close to the liquid surface of the mixed liquid. The linkage rod will move away from the limit ring, and the gas spring will move upward to the top linkage frame. The linkage frame will push the linkage pin, and the linkage pin will synchronously drive the lamp head to rotate along the rotation axis to achieve angle adjustment. This can be achieved during the process of adjusting the height of the lamp head, which is convenient and quick.

[0038] As an optional technical solution of the present invention, the spacing identification component includes

[0039] A telescopic rod, the telescopic rod being fixedly connected to the bottom surface of the annular seat;

[0040] A floating block, wherein the floating block is fixedly connected to the bottom end of the telescopic rod;

[0041] The distance sensor is fixedly mounted on the bottom surface of the annular seat and is used to detect the distance between the floating block and the bottom surface of the annular seat.

[0042] It should be understood that by detecting the distance between the floating block and the annular seat through the distance sensor, the distance between the lamp head and the annular seat as a whole and the mixed liquid surface can be clearly understood, thereby providing a basis for the height adjustment device to adjust the height of the annular seat and the lamp head as a whole, which is conducive to accurately adjusting the distance, maintaining the most ideal lighting distance, and providing a light source of reasonable intensity.

[0043] As a further optimized technical solution of the present invention, it also includes a stirring component, wherein the stirring component includes

[0044] A stirring shaft, the stirring shaft is rotatably connected to the cover body, and a stirring blade is fixedly connected to the surface;

[0045] The third motor is fixedly mounted on the top of the cover body, and the output end of the third motor is fixedly connected to the top end of the stirring shaft.

[0046] It should be understood that the mixture of solid microbial agent and water needs to be stirred to accelerate the mixing so as to evenly distribute the bacteria. When stirring is required, the third motor is started, the third motor drives the stirring shaft to rotate, and the stirring shaft synchronously drives the stirring blades to rotate, stirring the mixture of solid microbial agent and water to accelerate the mixing.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] The present invention synchronously adjusts the heights of multiple lamp heads so that the mixed solution of solid microbial agent and water is close to the light source. In the process of culture and amplification, the annular seat is continuously driven to rotate by the rotary adjustment unit, thereby driving the lamp heads to move along a circular trajectory, thereby achieving uniform irradiation of the mixed solution of solid microbial agent and water. On the one hand, the stability of the light source is ensured, and on the other hand, it is conducive to uniform illumination and to improving amplification efficiency.

[0049] The present invention adjusts the angle of the lamp head through the angle adjustment component, which is conducive to directing the irradiation direction of the lamp head toward the liquid surface, so that the light source can irradiate the liquid surface of the mixed liquid as much as possible, which is conducive to maximizing the use of the light source.

[0050] The present invention can clearly know the distance between the lamp head and the annular seat as a whole and the mixed liquid surface by detecting the distance between the floating block and the annular seat through the distance sensor, thereby providing a basis for the height adjustment device to adjust the height of the annular seat and the lamp head as a whole, which is conducive to accurately adjusting the distance, maintaining the most ideal lighting distance, and providing a light source with reasonable intensity.

[0066] It should be understood that after the solid microbial agent is added into the amplification tank 1 through the feeding valve 6, the cover body 2 is closed, and before the solid microbial agent is added, the annular seat 3 and the lamp head 4 of the illumination assembly are adjusted to the top of the inside of the amplification tank 1. After the solid microbial agent is added, water is passed into the amplification tank 1 through the injection valve 7. When the liquid level rises to the set height, the water supply is stopped, and then the height of the annular seat 3 is adjusted through the height adjustment unit according to the distance between the annular seat 3 and the liquid surface detected by the distance recognition assembly, that is, the heights of multiple lamp heads 4 are adjusted synchronously, so that the mixed liquid of the solid microbial agent and water is close to the light source, and in the process of culture and amplification, the annular seat 3 is continuously driven to rotate by the rotating adjustment unit, and then the lamp head 4 is driven to move along a circular trajectory, so as to realize uniform irradiation of the mixed liquid of the solid microbial agent and water. On the one hand, the stability of the light source is ensured, and on the other hand, it is conducive to uniform illumination and to improve the amplification efficiency.

[0067] Specifically, it also includes a probe 9 , which is arranged through the top right side of the amplification tank 1 and is used to monitor the inside of the amplification tank 1 .

[0068] The specific probe 9 is a temperature detection unit, which is used to stably detect and observe the temperature in the amplification tank 1 .

[0069] Specifically, it also includes an aeration member 10, which is arranged at the left bottom end and extends to the inside of the amplification tank 1 after penetrating the amplification tank 1. The aeration member 10 has aeration holes.

There are four height adjustment components, and the height adjustment components include a clearance groove 14, which is opened on the side of the amplification tank 1; a moving seat 15, which is slidably connected to the surface of the connecting ring 12; a threaded rod 16, which is threadedly connected to the moving seat 15, and the bottom end is fixedly connected to a first motor 17, and the first motor 17 is fixedly installed in the annular cover 13.

[0075] It should be understood that when the height of the annular seat 3 and the lamp head 4 needs to be adjusted, multiple first motors 17 are started at the same time, the first motors 17 drive the threaded rod 16 to rotate, the threaded rod 16 threadedly drives the moving seat 15 to lower the height, the moving seat 15 drives the connecting ring 12 to move, and the connecting ring 12 synchronously drives the annular seat 3 to move, thereby realizing the height adjustment of the lamp head 4 installed on the annular seat 3.

[0076] As an optional embodiment of the present invention, the rotation drive unit includes an annular rack 18, which is fixedly connected to the connecting ring 12; a second motor 19, which is fixedly connected to the moving seat 15, and the output end is fixedly connected to a driving gear 20 meshing with the annular rack 18.

[0077] It should be understood that when the lamp head 4 needs to be moved, the second motor 19 is started, the second motor 19 drives the driving gear 20 to rotate, the driving gear 20 transmits the annular rack 18, the annular rack 18 drives the connecting ring 12 to rotate, and the connecting ring 12 synchronously drives the annular seat 3 to rotate, thereby driving the lamp head 4 on the annular seat 3 to move in a circular trajectory.

[0078] It should be further explained that, by installing the rotary drive unit on the movable seat 15 , it is advantageous to synchronously adjust the rotary drive unit according to the adjustment of the height of the annular seat 3 , thereby avoiding obstacles.

[0079] As a further optimized embodiment of the present invention, it also includes multiple installation grooves 21, which are arranged in a circular array on the side wall of the annular seat 3, and multiple lamp heads 4 are rotatably installed in the multiple installation grooves 21 respectively; multiple angle adjustment components are used to adjust the angles of the multiple lamp heads 4 when the annular seat 3 moves downward to an ideal height.

On the one hand, it avoids interference with the feeding, and on the other hand, it avoids contamination of the lamp head 4 by the added material. After the feeding is completed, the height adjustment unit is used to adjust the annular seat 3 and the lamp head 4 as a whole to be close to the liquid surface of the mixed liquid. The linkage rod 25 will move away from the limiting ring 26, and the gas spring 24 will move upward to the top linkage frame 23. The linkage frame 23 will push the linkage pin 22, and the linkage pin 22 will synchronously drive the lamp head 4 to rotate about the rotation axis to achieve angle adjustment.

[0084] It should be understood that by detecting the distance between the floating block 28 and the annular seat 3 by the distance sensor 29, the distance between the lamp head 4 and the annular seat 3 as a whole and the mixed liquid surface can be clearly understood, thereby providing a basis for the height adjustment device to adjust the height of the annular seat 3 and the lamp head 4 as a whole, which is conducive to accurately adjusting the distance, maintaining the most ideal lighting distance, and providing a light source of reasonable intensity.
