Description

Technical Field

[0001] The invention relates to the technical field of sewage fermentation, and in particular to an intelligent fermentation system. Background Art

[0002] In the process of fermenting sewage with aerobic bacteria, the control of dissolved oxygen in the sewage to be treated is also key. Dissolved oxygen is generally controlled by controlling the amount of oxygen introduced into the sewage. If too much oxygen is introduced into the sewage, it may not be completely dissolved in the water, resulting in a waste of oxygen; too little oxygen introduced into the sewage may affect the activity of aerobic microorganisms. Generally, during the sewage fermentation process, an oxygen outlet device is installed at a fixed point in the fermentation tank.

[0003] Invention patent CN107986548B discloses "sewage treatment equipment", which specifically discloses that an air inlet is provided on the inner wall of the lower end of the water treatment chamber, and a stirring blade is arranged to rotate in the water treatment chamber, and the stirring blade is hinged on the stirring rod.

[0055] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0056] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0057] like Figures 1 to 9 As shown, an intelligent fermentation system, the fermentation system comprises:

[0058] A tank body 1, the tank body 1 is used to hold the sewage to be fermented; the tank body 1 is also connected with a sewage inlet pipe and a sewage outlet pipe, through which sewage can be added into the tank body 1, and through which the treated sewage can be discharged from the tank body 1;

[0059] A stirring unit, the stirring unit includes a plurality of stirring blades 21 and a stirring rod 22, the stirring rod 22 is a hollow tube, the stirring rod 22 is rotatably arranged in the pool body 1, and the stirring blades 21 are all arranged on the stirring rod 22;

[0060] The plurality of stirring blades 21 are arranged along the axis direction of the stirring rod 22, that is, the stirring blades 21 are arranged at different heights of the stirring rod 22;

[0061] An air intake unit, the air intake unit includes an air intake pipe 31, an air outlet 32, an external air supply device and a pressure control valve 33; a ventilation cavity 34 is provided in the stirring blade 21, and the ventilation cavity 34 is connected to the stirring rod 22 through a connecting hose 35. A plurality of air outlets 32 are provided through the stirring blade 21, and the plurality of air outlets 32 can be arranged at different positions of the stirring blade 21 along the length direction of the stirring blade 21. At the same time, since the plurality of stirring blades 21 are arranged at different heights of the stirring rod 22, when the stirring rod 22 rotates, different positions in the pool body 1 can be ventilated;

[0062] Furthermore, an air outlet 32 ​​may be provided on the end surface of the stirring blade 21 away from the stirring rod 22;

[0063] One end of the air inlet pipe 31 is connected to an external air supply device, and the other end of the air inlet pipe 31 is connected to one end of the stirring rod 22. A pressure control valve 33 is fixedly installed at the other end of the stirring rod 22. The pressure control valve 33 is used to automatically open when the pressure in the stirring rod 22 reaches a preset value, that is, when the air outlet 32 ​​is blocked, the pressure in the stirring rod 22 will increase. When the pressure in the stirring rod 22 increases to the preset value, the pressure control valve 33 automatically opens;

[0064] The pressure control valve 33 is not limited here. It is automatically opened when the pressure in the stirring rod 22 reaches a preset value. The pressure control valve 33 is an automatic pressure regulating safety valve. When the amount of sewage in the tank body 1 is different, the amount of oxygen required in the tank body 1 is also different. By adjusting the opening pressure of the automatic pressure regulating safety valve, the oxygen amount control for fermentation of different amounts of sewage can be adapted;

[0065] A temperature control unit, the temperature control unit includes a heater 4, the heater 4 is arranged on the intake pipe 31, the intake pipe 31 includes an intake hose, a rigid pipe and an intake connecting pipe, the intake hose, the rigid pipe and the intake connecting pipe are connected in sequence, the intake connecting pipe is connected to an external air supply device, the intake hose is connected to the stirring rod 22, in order to ensure the normal rotation of the stirring rod 22, the intake hose can be connected to the stirring rod 22 through a rotary joint, the heater 4 is installed on the rigid pipe, the heater 4 can be installed on the outer wall of the rigid pipe (in this case, the rigid pipe needs to be able to conduct heat), or can be fixedly installed on the inner wall of the rigid pipe;

[0066] The heater 4 is used to heat the gas flowing through the air inlet pipe 31. Due to the arrangement of the stirring blades 21 and the air outlet 32, after the heater 4 heats the oxygen flowing through the air inlet pipe 31, the oxygen ejected through the stirring rod 22, the ventilation cavity 34 and the air outlet 32 ​​will have a certain temperature, and different positions of the pool body 1 can be heated at the same time, and heat accumulation is avoided, thereby better ensuring the temperature of sewage fermentation.

[0067] In this embodiment, Figures 1 to 9 As shown, the stirring blade 21 is rotatably mounted on the stirring rod 22 , the rotation axis of the stirring blade 21 is perpendicular to the axis of the stirring rod 22 , and the axis of the stirring rod 22 is perpendicular to the bottom end surface of the pool body 1 .

[0068] By rotatably installing the stirring blade 21 on the stirring rod 22, a better stirring effect can be ensured, thereby enabling better sewage fermentation.

[0069] In this embodiment, Figures 1 to 9 As shown, the stirring blade 21 has two stirring surfaces, which are a first stirring surface 28 and a second stirring surface 29, respectively. The first stirring surface 28 is parallel to the second stirring surface 29;

[0070] The first stirring surface 28 forms an acute angle or an obtuse angle with the axis of the stirring rod 22, that is, the angle between the first stirring surface 28 and the axis of the stirring rod 22 at the upper right side of the stirring rod 22 is an acute angle, or the angle between the first stirring surface 28 and the axis of the stirring rod 22 at the upper right side of the stirring rod 22 is an obtuse angle.

[0071] In this embodiment, Figures 1 to 9As shown, the stirring unit further includes a rotation power assembly for driving the stirring rod 22 to rotate, and the rotation power assembly includes a support 23 and a forward and reverse rotation power element 24;

[0072] The support member 23 is disposed in the pool body 1. Here, the support member 23 is for providing support and may be a support plate or a support frame;

[0073] The forward and reverse rotation power element 24 is fixedly mounted on the support 23, and the stirring rod 22 is rotatably mounted on the support 23. The forward and reverse rotation power element 24 drives the stirring rod 22 to rotate. The forward and reverse rotation power element 24 drives the stirring rod 22 to rotate forward or reverse. The forward and reverse rotation power element 24 described here is to output a forward and reverse rotation power source to drive the stirring rod 22 to rotate forward and reverse. It can be a forward and reverse motor. The forward and reverse motor can be directly fixedly connected to the stirring rod 22 to drive the stirring rod 22 to rotate, or it can be a forward and reverse motor that drives the stirring rod 22 to rotate through a gear set.

[0074] By starting the forward and reverse motor to rotate forward, the stirring rod 22 can be driven to rotate forward, and by starting the forward and reverse motor to rotate reversely, the stirring rod 22 can be driven to rotate reversely.

[0075] During the stirring process of sewage fermentation, due to the large volume of the pool body 1, the rotation speed of the stirring blade 21 is generally not fast. When the angle between the first stirring surface 28 of the stirring blade 21 and the axis of the stirring rod 22 is an acute angle, the forward and reverse motor starts to rotate forward, driving the stirring rod 22 and the stirring blade 21 to rotate forward, which can provide a downward force for the first stirring surface 28, so that the stirring blade 21 can be in a downward tilted state (this is the first stirring blade 21 state). The forward and reverse motor starts to rotate reversely, driving the stirring rod 22 and the stirring blade 21 to reverse, which can provide an upward force for the first stirring surface 28, so that the stirring blade 21 can be in an upward tilted state (this is the second stirring blade 21 state). At this time, by alternately starting the forward and reverse motors to rotate forward and reverse, the stirring blade 21 can be switched between the first stirring blade 21 state and the second stirring blade 21 state, so that the fermented sewage can be more fully stirred and mixed, and the sewage fermentation can be better carried out.

[0076] In this embodiment, Figures 1 to 9 As shown, the stirring unit further includes an angle limiting component for limiting the rotation angle of the stirring blade 21, and the angle limiting component includes a sleeve 25, a through hole 26 and a lifting power element 27;

[0077] The sleeve 25 is slidably sleeved outside the stirring rod 22, and the sliding direction of the sleeve 25 is parallel to the axial direction of the stirring rod 22. A through hole 26 is formed through the sleeve 25, and the through hole 26 corresponds to the stirring blade 21 one by one. The stirring blade 21 passes through the through hole 26 and extends into the tank body 1.

[0078] There is a gap between the inner wall of the through hole 26 and the outer wall of the stirring blade 21, that is, the through hole 26 allows the stirring blade 21 to rotate up and down;

[0079] The lifting power element 27 is fixedly mounted on the stirring rod 22, and the telescopic end of the lifting power element 27 is fixedly connected to the sleeve 25, and the telescopic direction of the telescopic end of the lifting power element 27 is parallel to the sliding direction of the sleeve 25.

[0080] The lifting power element 27 is not limited here, as long as it can be extended and retracted, it can be an electric telescopic rod or a hydraulic cylinder.

[0081] The sleeve 25 is driven to move up and down by the lifting power element 27 , thereby driving the through hole 26 to change the up and down position of the through hole 26 , so as to limit the upward or downward rotation angle of the stirring blade 21 .

[0082] In this embodiment, Figures 1 to 9 As shown, the fermentation system further includes a lifting unit for driving the support member 23 to move up and down, and the lifting unit includes a first telescopic power element 51 and a second telescopic power element 52;

[0083] The first telescopic power element 51 and the second telescopic power element 52 are symmetrically arranged relative to the support member 23, and the telescopic axis of the first telescopic power element 51 forms an acute angle with the axis of the stirring rod 22 (that is, the angle between the telescopic axis of the first telescopic power element 51 and the axis of the stirring rod 22 below the telescopic axis of the first telescopic power element 51 is an acute angle), and the first telescopic power element 51 is rotatably mounted on the inner wall of the pool body 1, and the telescopic end of the first telescopic power element 51 is rotatably connected to the support member 23, and the rotation axis of the first telescopic power element 51 is perpendicular to the axis of the stirring rod 22;

[0084] The first telescopic power element 51 and the second telescopic power element 52 are not limited here. As long as they can be telescopic, they can be electric telescopic rods or hydraulic cylinders. Here, since the stirring blades 21, stirring rods 22, sleeves 25 and other parts are all supported by the first telescopic power element 51 and the second telescopic power element 52, and the weight of these parts is generally heavy, the first telescopic power element 51 and the second telescopic power element 52 are generally chosen to be hydraulic cylinders.

[0085] The telescopic axis of the first telescopic power element 51 forms an acute angle with the axis of the stirring rod 22. Since the first telescopic power element 51 and the second telescopic power element 52 are symmetrically arranged relative to the support member 23, the telescopic axis of the second telescopic power element 52 also forms an acute angle with the axis of the stirring rod 22, that is, oblique support is provided to the support member 23, and its support stability is stronger. At the same time, the support member 23 can be driven to rise by opening and closing the first telescopic power element 51 and the second telescopic power element 52, thereby changing the upper and lower positions of the stirring rod 22 in the pool body 1;

[0086] The specific steps for driving the support member 23 to rise are: start the first telescopic power element 51 to extend outward and close the second telescopic power element 52, so that the support member 23 can move diagonally to the upper left, and then start the second telescopic power element 52 to extend outward and close the first telescopic power element 51, so that the support member 23 can move diagonally to the upper right, thereby making the support member 23 rise.

[0087] In this embodiment, Figures 1 to 9 As shown, the fermentation system also includes a temporary expansion unit for instantaneously increasing the amount of sewage fermentation, and the temporary expansion unit includes an annular baffle 61, an annular lifting chamber 62, an annular through groove 63, a first connecting pipe 64 and a first air bag 65;

[0088] The pool body 1 is embedded in the ground, the annular lifting chamber 62 is opened underground, the annular lifting chamber 62 is located outside the pool body 1, the center line of the annular lifting chamber 62 is parallel to the center line of the pool body 1, and the upper end surface of the annular lifting chamber 62 is connected to the outside through the annular through groove 63;

[0089] The annular baffle 61 is located in the annular lifting chamber 62, the upper portion of the annular baffle 61 slides through the annular through groove 63 and extends out to the ground, and the side wall of the annular baffle 61 fits with the side wall of the annular through groove 63;

[0090] The bottom end surface of the annular baffle 61 is fixedly mounted with an annular stopper 66, and the upper portion of the annular stopper 66 is provided with an inclined surface, and the upper end surface of the annular lifting chamber 62 corresponds to the inclined surface. When the annular stopper 66 rises to the highest point, the inclined surface fits the upper end surface of the annular lifting chamber 62;

[0091] One end of the first connecting pipe 64 passes through the tank body 1 and is connected to the inside of the tank body 1, and the other end of the first connecting pipe 64 is connected to the upper part of the annular lifting chamber 62. The first connecting pipe 64 may be located at the upper part of the tank body 1;

[0092] The first airbag 65 is fixedly mounted on the bottom end surface of the annular stopper 66, and the sewage in the tank body 1 enters the annular lifting chamber 62 through the first connecting pipe 64, and the first airbag 65 floats up and drives the annular baffle 61 to rise;

[0093] The annular baffle 61 may be made of a carbon fiber composite material to reduce weight, so that the first airbag 65 can reliably drive the annular baffle 61 to float upward.

[0094] In the process of sewage fermentation, it is inevitable that a large amount of sewage will be generated instantaneously and needs to be fermented. Generally, the volume of the tank body 1 is fixed. If the large amount of sewage generated instantaneously exceeds the maximum volume of the tank body 1, it will overflow from the tank body 1, causing sewage leakage.

[0095] When a large amount of sewage is generated instantaneously, the sewage enters the annular lifting chamber 62 through the first connecting pipe 64. The sewage in the annular lifting chamber 62 gradually increases, which can make the first airbag 65 float in the annular lifting chamber 62, thereby driving the annular baffle 61 to rise, and expanding a accommodating area of ​​a certain height above the pool body 1, realizing the temporary expansion of the capacity of the pool body 1, thereby ensuring that more sewage can be fermented and preventing sewage from leaking everywhere.

[0096] In this embodiment, Figures 1 to 9 As shown, the temporary expansion unit further includes a second connecting pipe 71, an opening and closing plate 72 and a second air bag 73;

[0097] The second communicating tube 71 is tilted, the first end of the second communicating tube 71 is connected to the bottom of the annular lifting chamber 62, the second end of the second communicating tube 71 passes through the tank body 1 and is connected to the tank body 1, the horizontal height of the first end of the second communicating tube 71 is greater than the horizontal height of the second end of the second communicating tube 71, and the second end of the second communicating tube 71 is flush with the inner wall of the tank body 1 to ensure normal closure;

[0098] The opening and closing plate 72 is slidably disposed on the inner wall of the pool body 1, and the sliding direction of the opening and closing plate 72 is parallel to the center line direction of the pool body 1. The opening and closing plate 72 opens and closes the second end of the second connecting pipe 71;

[0099] The outer wall of the opening and closing plate 72 is in contact with the inner wall of the pool body 1. The opening and closing plate 72 may be made of carbon fiber composite material to reduce weight, so that the second airbag 73 can reliably drive the opening and closing plate 72 to float.

[0100] The inner wall of the tank body 1 is provided with a slide groove, the guide direction of the slide groove is parallel to the center line direction of the tank body 1, the slider is slidably installed in the slide groove, and the slider is fixedly connected to the opening and closing plate 72;

[0101] The second airbag 73 is fixedly mounted on the opening and closing plate 72. When the opening and closing plate 72 slides to the lowest position, the second airbag 73 is located below the second connecting tube 71. When the opening and closing plate 72 slides to the highest position, the second airbag 73 is located below the first connecting tube 64, and at this time, the opening and closing plate 72 can also close the second connecting tube 71.

[0102] The sewage level in the tank body 1 rises and drives the second air bag 73 to float up, thereby driving the opening and closing plate 72 to rise, and then closing the second connecting pipe 71.

[0103] The liquid level in the pool body 1 gradually rises, and when it contacts the second airbag 73, the buoyancy of the second airbag 73 can drive the opening and closing plate 72 to rise, so that the second connecting pipe 71 can be closed. When the liquid level gradually rises to the first connecting pipe 64, the sewage flows into the annular lifting chamber 62, so that the annular baffle 61 can be driven up by the first airbag 65, thereby realizing the temporary expansion of the capacity of the pool body 1. When the sewage in the pool body 1 is discharged, the liquid level in the pool body 1 gradually decreases. When the liquid level drops to below the lowest point of the second airbag 73, the opening and closing plate 72 decreases under the action of gravity and opens the second connecting pipe 71, so that the sewage in the annular lifting chamber 62 can also be discharged into the pool body 1, avoiding the accumulation of sewage in the annular lifting chamber 62.
