[0081] The turntable bioreactor provided by the present invention utilizes the rotation of the rotary power prime mover 12 to make the rotary power output shaft perform a rotational motion.

In the turntable bioreactor provided by the present invention, since the lowest position point of the diaphragm assembly 11 is lower than the bottom edge of the water inlet and the water outlet, when the sewage to be treated is passed into the shell 51, the diaphragm assembly 11 can at least partially contact the sewage to be treated, that is, on the diaphragm assembly 11, the Bacillus microorganisms attached to the part of the diaphragm assembly 11 that contacts the sewage to be treated can use the pollutants in the sewage as nutrients and degrade the pollutants in the sewage through metabolism in the body, thereby achieving sewage purification. However, during the operation of the diaphragm assembly 11, as the amount of sewage treated increases, a microbial film will be continuously suspended on the diaphragm assembly 11. In a short period of time, the microbial film is loosely combined with the diaphragm assembly 11. Therefore, by blowing the diaphragm assembly 11 through the aeration device 18, the microbial film loosely combined with the diaphragm assembly 11 can be at least partially detached. Therefore, after adding the aeration device 18, the thickening rate of the microbial film attached to the diaphragm assembly 11 of the turntable bioreactor provided by the present invention can be significantly reduced. Therefore, damage to the diaphragm assembly 11 caused by overload operation of the diaphragm assembly 11 can be avoided.

[0082] The operating method, operating device, computer-readable storage medium and terminal device of the turntable bioreactor provided by the present invention can enable the rotary power output shaft of the rotary power driving member 12 to reach a stable rated speed by slowly increasing the speed, and after running at the rated speed for a set time, it can be braked by slowly decelerating the speed. That is to say, under the conditions of the turntable bioreactor provided by the present invention, the diaphragm assembly 11 can reach a stable rated speed by slowly increasing the speed, and after running at the rated speed for a set time, it can be braked by slowly decelerating the speed. Therefore, not only can the energy-saving effect be achieved, but also the anti-fatigue performance of the rotary power driving member 12 during the starting or braking process can be avoided, thereby increasing the service life of the turntable bioreactor provided by the present invention.

[0109] In view of this, the present invention provides a turntable bioreactor and an operating method thereof, which can reduce the adhesion thickness of the biofilm suspended on the diaphragm by purging the diaphragm to extend the service life of the diaphragm, thereby being more suitable for practical use.

[0110] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is combined with the accompanying drawings and preferred embodiments to describe a turntable bioreactor and its operation method proposed according to the present invention. By purging the diaphragm, the thickness of the biofilm suspended on the diaphragm can be reduced to extend the service life of the diaphragm. The specific implementation method, structure, features and effects thereof are described in detail as follows. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0111] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B. Specifically, it is understood that: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may be met.

[0112] Embodiment 1

[0113] See attached Figure 1 -Attached Fig.19The turntable bioreactor provided in the first embodiment of the present invention includes a shell 51, a diaphragm assembly 11, a main transmission shaft 22, a slave transmission shaft 20, a rotary power driving member 12 and an aeration device 18. The shell 51 has an accommodating space inside, and a water inlet and a water outlet are provided on the shell 51. The main transmission shaft 22 is fixedly connected to one axial end of the diaphragm assembly 11, and the slave transmission shaft 20 is fixedly connected to the other axial end of the diaphragm assembly 11. The diaphragm assembly 11 is arranged in the accommodating space through the main transmission shaft 22 and the slave transmission shaft 20. The rotary power output shaft of the rotary power driving member 12 is fixedly connected to the main transmission shaft 22. The gas generated by the aeration device 18 can purge the diaphragm assembly 11. Bacillus microorganisms are attached to the diaphragm assembly 11.

[0114] The turntable bioreactor provided by the present invention utilizes the rotation of the rotary power prime mover 12 to make the rotary power output shaft perform a rotational motion. At this time, since the rotary power output shaft is fixedly connected to the main transmission shaft 22, the main transmission shaft 22 can perform a rotational motion together with the rotary power output shaft, thereby driving the diaphragm assembly 11 to perform a rotational motion together with the rotary power output shaft. In the turntable bioreactor provided by the present invention, since the lowest position point of the diaphragm assembly 11 is lower than the bottom edge of the water inlet and the water outlet, when the sewage to be treated is passed into the shell 51, the diaphragm assembly 11 can at least partially contact the sewage to be treated, that is, on the diaphragm assembly 11, the Bacillus microorganisms attached to the part of the diaphragm assembly 11 that contacts the sewage to be treated can use the pollutants in the sewage as nutrients and degrade the pollutants in the sewage through metabolism in the body, thereby achieving sewage purification. However, during the operation of the diaphragm assembly 11, as the amount of sewage treated increases, a microbial film will be continuously suspended on the diaphragm assembly 11. In a short period of time, the microbial film is loosely combined with the diaphragm assembly 11. Therefore, by blowing the diaphragm assembly 11 through the aeration device 18, the microbial film loosely combined with the diaphragm assembly 11 can be at least partially detached. Therefore, after adding the aeration device 18, the thickening rate of the microbial film attached to the diaphragm assembly 11 of the turntable bioreactor provided by the present invention can be significantly reduced. Therefore, the damage of the diaphragm assembly 11 caused by the overload operation of the diaphragm assembly 11 can be avoided. In this embodiment, in order to facilitate the connection between the main transmission shaft 22 and the rotary power output shaft of the rotary power driving member 12, the main transmission shaft 22 and the rotary power output shaft of the rotary power driving member 12 are connected by a key 23. In this embodiment, for the convenience of processing, the key 23 is a straight key.

[0115] The housing 51 includes an upper housing 4 and a lower housing 5. The upper housing 4 and the lower housing 5 are fixedly connected together to form a storage space. In this case, the upper housing 4 and the lower housing 5 can be manufactured separately. During assembly, the lower housing 5 is first placed in a designated position, and then, after the diaphragm assembly 11 is assembled with the upper housing 4, it is hoisted to the lower housing 5. The upper housing 4 and the lower housing 5 are respectively provided with connecting edges at the connection position, and then bolts are used to fasten the connection. In order to make it more convenient to hoist the upper housing 4 and the diaphragm assembly 11 in place after assembly, a hoisting hole 8 can also be provided on the top of the upper housing 4. The hoisting hole 8 can be a through hole or a blind hole, as long as the hook of the hoisting device can be inserted. In order to make the storage space formed after the upper housing 4 and the lower housing 5 are assembled ventilated and easy to observe, a plurality of shutters 7 can also be provided on the upper housing 4, and the storage space formed between the upper housing 4 and the lower housing 5 can be connected to the outside through the plurality of shutters 7.

[0116] Among them, the water inlet and the water outlet are arranged at the upper edge of the lower shell 5. In this case, the sewage to be treated can fully utilize the accommodation space of the lower shell 5, so that more sewage to be treated can be accommodated in the lower shell 5 per unit time. In this embodiment, the upper shell 4 is semi-cylindrical as a whole. In this case, when the water inlet and the water outlet are arranged at the upper edge of the lower shell 5, a reasonable installation position can be provided for the installation of the diaphragm assembly 11. In particular, when the diaphragm assembly 11 is just half immersed in the lower shell 5, as the rotary power output shaft of the rotary power prime mover 12 rotates, each position of each diaphragm 1 of the diaphragm assembly 11 can contact the sewage to be treated, so that the diaphragm assembly 11 can be more fully utilized.

[0117] The turntable bioreactor further includes an overflow tank 47. A notch 46 is provided on the upper edge of the lower shell 5, and the overflow tank 47 is externally mounted on the lower shell 5, and the receiving interface of the overflow tank 47 corresponds to the notch 46. In this case, if the lower shell 5 of the turntable bioreactor provided in the first embodiment of the present invention contains a large amount of sewage to be treated, which exceeds the lowest position of the notch 46, the overflowed water can flow from the notch 46 into the overflow tank 47, that is, by observing the overflow tank 47, it can be easily known whether the water injected into the lower shell 5 has reached the critical position.

[0118] Wherein, the overflow trough 47 includes an inclined plate 48 and two side plates 49. The inclined plate 48 is fixedly connected to the outer side of the two side plates 49 so that the bottom surface of the overflow trough 47 forms a seal. When the sewage to be treated in the lower shell 5 exceeds the lowest position point of the notch 46, it will overflow from the notch 46. When the overflow begins, the flow rate is large, so the overflow distance is far. As the water gradually overflows, the flow rate will also decrease. Therefore, the two side plates 49 can be designed to have a large upper opening and a small lower opening. In this embodiment, the two side plates 49 are both right-angled triangles, one of the right-angled sides of the right-angled triangle is fixedly connected to the outer wall of the lower shell 5, and the inclined plate 48 is fixedly connected to the hypotenuse of the right-angled triangle. In this case, the bottom of the inclined plate 48 is fixedly connected to the outer wall of the lower shell 5, and the overflow trough 47 is formed between the outer wall of the lower shell 5, the two side plates 49 and the inclined plate 48.

[0119] Wherein, the turntable bioreactor device further comprises a sealing ring. The sealing ring is arranged between the corresponding connection surfaces of the upper shell 4 and the lower shell 5, so that a seal is formed between the corresponding connection surfaces of the upper shell 4 and the lower shell 5. In this case, it is possible to prevent the sewage to be treated from overflowing from the corresponding connection surfaces between the upper shell 4 and the lower shell 5, causing the outer wall of the lower shell 5 to be dirty or even secondary pollution. In this embodiment, an extension edge is arranged outside the bottom edge of the upper shell 4 and the top edge of the lower shell 5, and a bolt hole is arranged at the corresponding position of the extension edge. By tightening the bolts, the two extension edges are fixed together, so that the upper shell 4 and the lower shell 5 can be fixed. The sealing ring is clamped between the two extension edges. For example, the material of the sealing ring can be rubber. In this case, the connection between the upper shell 4 and the lower shell 5 can be sealed by utilizing the fact that the rubber itself can be deformed under pressure and has a certain shape recovery tendency.

[0120] The diaphragm assembly 11 includes a plurality of diaphragm units 52, which are connected in series. The diaphragm units 52 include a plurality of fan-shaped diaphragms 1. The diaphragm assembly 11 also includes a series assembly, which includes a mandrel 50. The plurality of fan-shaped diaphragms 1 are fixedly connected to the mandrel 50 through their ends with smaller diameters, so that the ends with larger diameters of the diaphragm units 52 are cocircular. In this embodiment, the central angle of the fan-shaped diaphragm 1 is 60°, that is, each diaphragm unit 52 is composed of 6 diaphragms 1.

[0121] The turntable bioreactor device further includes a series assembly and a diaphragm support rod 2. The diaphragm 1 is provided with a support through hole, and the number of the diaphragm support rods 2 corresponds to the number of the support through holes, and the diaphragm support rods 2 are fixedly penetrated in the support through holes. In this case, each diaphragm unit 52 is supported in the axial direction by the rigid support of the diaphragm support rod 2 itself, which can ensure that the spacing between each diaphragm unit 52 of the diaphragm assembly 11 used in the turntable bioreactor device provided in the first embodiment of the present invention is constant.

[0122] A damping member is provided between the supporting through hole and the diaphragm support rod 2. The damping member can increase the friction resistance between the diaphragm support rod 2 and the diaphragm 1, thereby ensuring the connection stability between the diaphragm 1 and the diaphragm support rod 2. In this embodiment, the damping member can be composed of a rubber spacer.

[0123] Among them, each membrane 1 constituting the membrane unit 52 is in a mesh shape. In this case, since each membrane 1 constituting the membrane unit 52 is in a mesh shape, a larger specific surface area can be provided, so that more biofilms can be suspended, that is, in this case, the turntable bioreactor provided in the first embodiment of the present invention can have a better sewage treatment efficiency.

[0124] Among them, each diaphragm 1 constituting the diaphragm unit 52 is made of polyvinylidene chloride material. Polyvinylidene chloride (PVDC) is abbreviated as PVDC. The homopolymer and copolymer of vinylidene chloride are usually called Saran resin. Its commercial polymer is a copolymer of vinylidene chloride (VDC) and vinyl chloride, acrylate or acrylonitrile. The selection of comonomers has a great influence on the properties of the copolymer. The morphology of the copolymer should be determined according to processing methods such as melt processing, solution coating, and dispersion coating.

[0125] The aeration device 18 includes an air inlet pipe 28, an aeration pipe 53 and a bracket 30. One end of the air inlet pipe 28 is used to connect to the blower, and the other end of the air inlet pipe 28 is connected to the aeration pipe 53. The aeration pipe 53 is mounted on the bracket 30. A plurality of through holes 34 are arranged on the wall of the aeration pipe 53. The air inlet pipe 28 and the aeration pipe 53 are connected to each other and are connected to the accommodating space through the plurality of through holes 34. In this embodiment, the length of the aeration pipe 53 is greater than the axial length of the diaphragm assembly 11, that is, the diaphragm assembly 11 can be fully covered by the aeration pipe 53 in the axial direction, and the aeration pipe 53 is at the bottom of the lower shell 5, that is, the diaphragm assembly 11 attached with Bacillus microorganisms can be timely purged by the gas flowing out of the through hole 34 in real time during sewage treatment, which has a significant effect on preventing the thickening of the biofilm on the diaphragm assembly 11.

[0126] The bottom of the side wall of the housing 51 is provided with a drain hole 10, through which the accommodating space is connected with the outside world. In this case, the dirt that cannot be effectively processed can be efficiently discharged from the drain hole 10.

[0127] In the turntable bioreactor provided in the first embodiment of the present invention, the rotary power driving member 12 is a reducer, which is fixedly connected to the housing 6 through the support mechanism 13 and the second support mechanism 16. The support mechanism 13 includes a first support plate 35, a first reinforcing rib 36, a second reinforcing rib 37 and a buffer sleeve 38, and the second support mechanism 16 includes a second support plate (not numbered in the figure) and two connecting ears 60, and the two connecting ears 60 are fixedly connected to the upper surface of the second support plate (not numbered in the figure), wherein the first support plate 35 is fixedly connected to the outer wall of the lower housing 5, the first reinforcing rib 36 is fixedly connected between the first support plate 35 and the outer wall of the lower housing 5, and plays a role of longitudinal support for the first support plate 35, and the second reinforcing rib 37 is fixedly connected to the outer wall of the lower housing 5. The lower part of the first support plate 35 plays a role of lateral support for the first support plate 35. The buffer sleeve 38 is arranged at the bottom of the first reinforcing rib 36 and the second reinforcing rib 37 and is fixedly connected to the bottom of the first reinforcing rib 36 and the second reinforcing rib 37. The axial center of the buffer sleeve 38 is provided with a through hole 39. A buffer washer 40 is fixedly sleeved around the buffer pin 14 in the circumferential direction. The buffer pin 14 is simultaneously penetrated through the through holes provided on the two connecting ears and the buffer sleeve 38, wherein the buffer washer 40 is arranged between the inner wall of the buffer sleeve 38 and the buffer pin 14. Generally, the reducer will generate vibration during the rotation of the output shaft. In the case of the turntable bioreactor provided in the first embodiment of the present invention, the vibration generated by the reducer during the rotation of the output shaft can be weakened by the buffer washer, so that the influence of the vibration of the reducer during operation on the turntable bioreactor provided in the first embodiment of the present invention can be reduced. In the present embodiment, in order to position the buffer pin 14 between the two connecting ears 60, a positioning through hole 41 is further opened in the radial direction of the buffer pin 14. By inserting an open pin therein, the buffer pin can be prevented from falling out of the positioning through hole on the two connecting ears 60. In addition, a protrusion is provided at the other end of the buffer pin 14. The diameter of the protrusion is larger than the diameter of the through holes on the two connecting ears. When inserting, the small head side of the buffer pin 14 is inserted into the through holes of the two connecting ears 60, and then an open pin is inserted into the positioning through hole to position the buffer pin.

[0128] Among them, diaphragm positioning plates 59 are provided on both sides of the diaphragm 1, and the diaphragm positioning plates 59 are axially arranged at the center of the diaphragm 1. When the diaphragm units 52 are connected in series, the diaphragm positioning plates 59 abut against each other. Since the diaphragm positioning plates 59 themselves have a certain rigidity in the axial direction, it can ensure that the distance between the diaphragms 1 is constant. During use, the utilization efficiency of the diaphragm 1 can be made more stable.

[0129] Embodiment 2

[0130] See attached Fig. 20 The operation method of the turntable bioreactor provided in the second embodiment of the present invention comprises the following steps:

[0131] Step S1: the rotary power driving member 12 responds to the start control signal to start the rotary power output shaft;

[0132] Step S2: The rotating power output shaft is accelerated to rotate at a first set acceleration;

[0133] Step S3: when the rotating power output shaft reaches the rated speed, the first set acceleration is zero;

[0134] Step S4: rotating the power output shaft to maintain a constant speed at the rated speed;

[0135] Step S5: when the rotational power output shaft needs to be braked, the rotational power driving member (12) responds to the braking control signal to cause the rotational power output shaft to decelerate at a second set acceleration;

[0136] Step S6: When the braking of the rotating power output shaft is completed, the second set acceleration is zero.

[0137] The first set acceleration is greater than zero, and the second set acceleration is less than zero.

[0138] The operating method of the turntable bioreactor provided by the present invention can make the rotary power output shaft of the rotary power driving member 12 reach a stable rated speed by slowly increasing the speed, and when the rotary power output shaft needs to be braked, it can be braked by slowly decelerating the speed. That is to say, under the conditions of the turntable bioreactor provided by the present invention, the diaphragm assembly 11 can reach a stable rated speed by slowly increasing the speed, and after running at the rated speed for a set time, it can be braked by slowly decelerating the speed. Therefore, not only can the energy-saving effect be achieved, but also the anti-fatigue performance of the rotary power driving member 12 during the starting or braking process can be avoided, thereby increasing the service life of the turntable bioreactor provided by the present invention.

[0139] The first starting and braking method provided by the embodiment of the present invention is as follows:

[0140] like Fig.21 As shown, it is a curve diagram of the corresponding relationship between the rotation speed of the rotary power output shaft of the rotary power driving member 12 and time during one cycle of operation of the first turntable type bioreactor provided in the second embodiment of the present invention, wherein the slope of the curve represents the rotation speed acceleration of the rotary power output shaft, wherein, in the starting stage, the acceleration a1=10r / min 2 , and in the braking stage, the acceleration a2 = -10r / min 2 In this case, the technical effect of slow starting and slow braking can be achieved.

[0141] The second starting and braking method provided by the embodiment of the present invention is as follows:

[0142] like Fig. 22 As shown, it is a curve diagram of the corresponding relationship between the rotation speed of the rotary power output shaft of the rotary power driving member 12 and time during one cycle of operation of the second turntable bioreactor provided in the second embodiment of the present invention, wherein the slope of the curve represents the rotation speed acceleration of the rotary power output shaft. In this case, at the beginning of the startup, the acceleration of the rotation speed of the rotary power output shaft increases step by step. For example, the step-by-step acceleration may increase by 1 r / min every 2 min. 2 At this time, it is equivalent to starting warm-up. When the acceleration increases to a1 = 10r / min 2 After that, the rotation power output shaft is accelerated at a1 = 10r / min 2 When the speed of the rotating power output shaft increases to n1, since n1 is close to the rated speed n of the rotating power output shaft, e Therefore, after the speed of the rotary power output shaft increases to n1, the acceleration is gradually reduced. For example, the gradually reduced acceleration can be reduced by 1r / min every 2min. 2 In this case, when the speed reaches n e When the acceleration is reduced to 0, the slow start effect can be achieved. That is to say, when the time reaches t1, the speed of the rotating power output shaft reaches n e After that, the turntable bioreactor provided in the first embodiment of the present invention continues to operate stably until time t2, wherein time t2 is the time when the rotating power output shaft needs to be braked. At this time, the turntable bioreactor provided in the first embodiment of the present invention starts braking. In the same case, at the beginning of braking, a constant acceleration deceleration can be maintained. For example, the braking starting acceleration value can be increased step by step. However, since the braking acceleration is negative, the rotation speed of the rotating power output shaft is gradually reduced. For example, the gradually decreasing acceleration can be reduced by 1 r / min every 2 minutes. 2 , which is equivalent to brake warm-up. When the acceleration increases to a2 = -10r / min 2 After that, the rotation power output shaft is accelerated at a2 = -10r / min 2 When the speed of the rotating power output shaft is reduced to n2, since n2 is close to 0, the acceleration is gradually reduced after the speed of the rotating power output shaft is reduced to n2. For example, the gradually reduced acceleration can be reduced by 1r / min every 2min. 2In this case, when the speed reaches 0, the acceleration is also reduced to 0, and the slow start effect can be achieved. In this case, not only can the slow deceleration of the rotating power driving part be achieved, but also the rotating power driving part can be further protected from burning due to temporary overcurrent during the initial start, the middle start, the end of the start, the initial braking, the middle braking, and the end of the braking process.

[0143] Wherein, after the rotation power output shaft is braked in step S6, the following steps are also included:

[0144] Step S7: After pausing for a second set time, the power output shaft is rotated to repeat the above steps S1 to S6.

[0145] In this case, the turntable bioreactor provided in the first embodiment of the present invention can have an intermittent time, which can avoid the possibility of burning due to excessive motor temperature when it is in continuous operation. Therefore, the service life of the turntable bioreactor provided in the first embodiment of the present invention can be further improved.

[0146] After the second set time interval, the rotating power output shaft repeats the above steps, and the rotating power output shaft rotates in the same direction as or opposite to the previous direction. In this case, the rotation direction of the rotating power driving member can be adjusted to reduce fatigue damage caused by unidirectional rotation of the rotating power driving member, thereby further improving the service life of the turntable bioreactor provided in the first embodiment of the present invention.
