Description

Technical Field

[0001] This invention belongs to the field of aquatic aeration technology, and in particular relates to an aeration and stirring device. Background Technology

[0002] Aeration devices are used to enrich the oxygen content of water, increasing the oxygen concentration in the water. Traditional aeration devices include an aeration tank, an aeration port, and an inlet and outlet. In the prior art, such as Chinese patent CN114349189B, an environmentally friendly wastewater aeration device is disclosed, which includes a cylindrical aeration tank and a rotating ring at the bottom of the aeration tank. The rotating ring can rotate and rise and fall to aerate water at different depths. However, when the height of the rotating ring increases, the wastewater at the bottom of the aeration tank will no longer be aerated. When the height of the rotating ring decreases, the aeration degree of the wastewater at a shallower depth in the aeration tank is reduced, resulting in uneven aeration and reduced aeration efficiency. Summary of the Invention

[0003] Therefore, it is necessary to provide an aeration mixing device to address the problem that current aeration equipment cannot achieve the same aeration level in water bodies of different depths, which leads to uneven aeration.

[0004] The above objectives are achieved through the following technical solutions:

[0005] An aeration and stirring device, comprising:

[0006] The outer shell contains an aeration chamber. The outer shell is equipped with a feed inlet, a discharge outlet, and an air inlet pipe. External materials enter the aeration chamber through the feed inlet, and materials in the aeration chamber are discharged from the outer shell through the discharge outlet. External air enters the aeration chamber through the air inlet pipe.

[0007] The first aeration pipe is used to aerate the material in the aeration chamber. The first aeration pipe is connected to the air inlet pipe and has a first aeration hole. The first aeration hole is obliquely downward on the first aeration pipe. External air enters the first aeration pipe through the air inlet pipe, and the air in the first aeration pipe enters the aeration chamber through the first aeration hole. The first aeration pipe is located at the bottom of the aeration chamber and can rotate. The first aeration pipe has a spiral structure. When the rotation speed of the first aeration pipe increases, the pitch of the first aeration pipe decreases. The greater the resistance of the material, the greater the decrease in the pitch of the first aeration pipe.

[0008] A stirring component is used to stir the bubbles released by the first aeration pipe to make the material at different depths aerated evenly. The stirring component is set above the first aeration pipe, and the rotation of the stirring component drives the first aeration pipe to rotate.

[0009] A speed reduction assembly that makes the rotational speed of the first aeration pipe less than the rotational speed of the stirring assembly.

[0010] Furthermore, the first aeration pipe is made of a flexible material.

[0011] Furthermore, a support plate is provided on the first aeration pipe, and the support plate is arranged in contact with the pipe wall of the first aeration pipe to increase the rigidity of the first aeration pipe and prevent the first aeration pipe from undergoing plastic deformation when the speed increases.

[0012] Furthermore, it also includes support wheels, which are rotatably connected to the bottom of the first aeration pipe, and there are multiple support wheels.

[0013] Furthermore, the elastic element is fixed between the support wheels. When the rotational speed of the first aeration pipe increases, the elastic element makes the pitch of each part of the first aeration pipe change uniformly, preventing the first aeration pipe from undergoing plastic deformation.

[0014] Furthermore, the stirring assembly includes a drive motor, a rotating shaft, and stirring blades.

[0015] The drive motor is fixed to the outer casing. The drive motor can drive the rotating shaft to rotate. The rotating shaft is fixed to the stirring blade. The rotation of the rotating shaft drives the stirring blade to stir the material.

[0016] After the speed V1 of the stirring component is maintained for a first preset time, the speed of the stirring component is adjusted to V2. After the speed V2 of the stirring component is maintained for a second preset time, the speed of the stirring component is adjusted back to V1.

[0017] Furthermore, the stirring assembly also includes a rotating disk, which is disposed between the rotating shaft and the stirring blades. The rotating shaft rotates and drives the stirring blades to rotate through the rotating disk.

[0018] Furthermore, the stirring blade has a fixed end, a first blade portion and a second blade portion. The fixed end is fixedly connected to the rotating disk, and the first blade portion and the second blade portion are fixedly connected to the fixed end. The first blade portion and the second blade portion are arc-shaped plates with arc-shaped cross-sections.

[0019] Furthermore, it also includes a rotating shaft and a ventilator, and the deceleration assembly includes a first fixed plate, a second fixed plate, a fixed ring, a fixed shaft, and a second gear.

[0020] A first gear is provided on the rotating shaft, and the first gear is fixedly connected to the rotating shaft. The rotation of the rotating shaft drives the first gear to rotate.

[0021] One end of the ventilator is rotatably connected to the air inlet pipe, and the other end of the ventilator is rotatably connected to the fixing ring. The ventilator is connected to the first aeration pipe, and the rotation of the ventilator drives the first aeration pipe to rotate.

[0022] One end of the first fixing plate is fixedly connected to the inner wall of the outer shell, and the other end of the first fixing plate is fixedly connected to the fixing ring. The fixing ring is disposed between the rotating shaft and the ventilator. The second fixing plate is fixedly connected to the inner wall of the fixing ring. The fixing shaft is fixed on the second fixing plate, and the second gear is rotatably connected to the fixing shaft.

[0023] The inner wall of the ventilation cylinder is equipped with internal gears.

[0024] The second gear meshes with the first gear, and simultaneously with the internal gear. The pitch circle diameter of the first gear is smaller than that of the internal gear.

[0025] The rotation of the rotating shaft drives the first gear to rotate, the rotation of the first gear drives the second gear to rotate, the rotation of the second gear drives the internal gear to rotate, the rotation of the internal gear drives the air cylinder to rotate, and the rotation of the air cylinder drives the first aeration pipe to rotate.

[0026] Furthermore, it also includes a second aeration pipe and a baffle plate.

[0027] The second aeration pipe is fixed to the bottom of the outer shell and is connected to the air inlet pipe.

[0028] The second aeration pipe is provided with a second aeration hole, which is set at an angle downward. Air in the air inlet enters the second aeration hole pipe, and air in the second aeration pipe is discharged into the aeration chamber through the second aeration hole.

[0029] The guide plate is inclinedly disposed on the inner wall of the outer shell, and the inclination angle of the guide plate can be adjusted. The guide plate is disposed above the second aeration hole, so that the bubbles discharged from the second aeration hole are guided to the stirring component, making the aeration of the material more uniform.

[0030] The beneficial effects of this invention are:

[0031] 1. By rotating the first aeration pipe, materials with greater depth can be fully aerated, and the rotation of the stirring component can ensure that materials with less depth are fully aerated, thus achieving uniform aeration of materials at different depths and improving aeration efficiency.

[0032] 2. The deceleration component makes the rotation speed of the first aeration pipe less than that of the stirring component, which helps the stirring component to fully mix the bubbles released by the first aeration pipe into the shallow material, thereby improving oxygen utilization and increasing aeration efficiency.

[0033] 3. Intermittently increase the rotation speed of the first aeration pipe and the stirring component to reduce the pitch of the first aeration pipe during rotation, making the bubbles released by the first aeration pipe denser, providing more bubbles for the stirring component, and making the aeration of materials with shallow depth more complete.

[0034] 4. A support plate is provided on the first aeration pipe to improve the rigidity of the first aeration pipe, prevent plastic deformation of the first aeration pipe during rotation, and increase the reliability of the device of the present invention.

[0035] 5. The support wheels reduce the friction when the first aeration pipe rotates, prevent the first aeration pipe from directly contacting the bottom of the outer shell, and reduce the wear rate of the first aeration pipe.

[0036] 6. The first aeration hole is set diagonally below the first aeration pipe, and the second aeration pipe is set diagonally below the second aeration pipe to prevent debris in the aeration chamber from clogging the first and second aeration pipes, thereby increasing the reliability of the device of the present invention.

[0061] The following reference Figures 1 to 15 This invention describes an aeration and stirring device according to an embodiment of the present invention.

[0062] like Figures 1 to 5 As shown, an aeration and stirring device includes:

[0063] The outer shell 100 has an aeration chamber 102 inside. The outer shell 100 is provided with a feed inlet 104, a discharge outlet 106 and an air inlet pipe 108. External materials enter the aeration chamber 102 through the feed inlet 104, and the materials in the aeration chamber 102 can be discharged from the outer shell 100 through the discharge outlet 106. External air enters the aeration chamber 102 through the air inlet pipe 108.

[0064] The first aeration pipe 110 is used to aerate the material in the aeration chamber 102. The first aeration pipe 110 is connected to the air inlet pipe 108. The first aeration pipe 110 is provided with a first aeration hole 115, which is obliquely downward on the first aeration pipe 110. External air enters the first aeration pipe 110 through the air inlet pipe 108, and the air in the first aeration pipe 110 enters the aeration chamber 102 through the first aeration hole 115. The first aeration pipe 110 is located at the bottom of the aeration chamber 102 and can rotate. The first aeration pipe 110 has a spiral structure. When the rotation speed of the first aeration pipe 110 increases, the pitch of the first aeration pipe 110 decreases. The greater the resistance of the material, the greater the decrease in the pitch of the first aeration pipe 110.

[0065] The stirring component 200 is used to stir the bubbles released by the first aeration pipe 110 so that the materials at different depths are aerated evenly. The stirring component 200 is set above the first aeration pipe 110. The rotation of the stirring component 200 drives the first aeration pipe 110 to rotate.

[0066] The speed reduction component 300 reduces the rotational speed of the first aeration pipe 110 to less than the rotational speed of the stirring component 200.

[0067] Material enters the aeration chamber 102 of the outer shell 100 through the feed inlet 104. After the material in the aeration chamber 102 is aerated, it is discharged from the aeration chamber 102 through the discharge outlet 106. During the aeration process, the first aeration pipe 110 rotates, so that the material at the bottom of the aeration chamber 102 is fully aerated. The rotation speed of the stirring component 200 and the first aeration pipe 110 is increased, the pitch of the first aeration pipe 110 is reduced, and the released bubbles are more concentrated. The stirring component 200 can stir more bubbles, so that the material with a shallow depth in the aeration chamber 102 can also be fully aerated, improving the aeration efficiency. It can also make the material of different depths uniformly aerated, avoiding the problem of uneven aeration of materials of different depths in the prior art.

[0068] Furthermore, the first aeration pipe 110 is made of a flexible material, and when the rotational speed of the first aeration pipe 110 increases, the pitch of the first aeration pipe 110 can be reduced.

[0069] When the rotational speed of the first aeration pipe 110 is V1, such as Figure 14 As shown, the pitch of the first aeration pipe 110 remains constant; when the rotational speed of the first aeration pipe 110 increases, as... Figure 15 As shown, the pitch of the first aeration pipe 110 is reduced.

[0070] Furthermore, such as Figures 2 to 6As shown, a support plate 130 is provided on the first aeration pipe 110. The support plate 130 is in contact with the pipe wall of the first aeration pipe 110 to increase the rigidity of the first aeration pipe 110 and prevent the first aeration pipe 110 from undergoing plastic deformation when the speed increases.

[0071] In one embodiment, the support plate 130 is an annular plate, and the support plate 130 is disposed in contact with the inner wall of the first aeration pipe 110; in another embodiment, the support plate 130 is a strip-shaped reinforcing rib, and is disposed in contact with the inner wall of the first aeration pipe 110; in some embodiments, such as Figure 5 As shown, the support plate 130 has the forms of both of the above embodiments; in one embodiment, the support plate 130 is a strip reinforcing rib, and the support plate 130 is arranged in contact with the outer wall of the first aeration pipe 110.

[0072] A support plate 130 is provided on the first aeration pipe 110 to improve the rigidity of the first aeration pipe 110, prevent the first aeration pipe 110 from undergoing plastic deformation during rotation, and increase the reliability of the device of the present invention.

[0073] In one embodiment, such as Figure 7 As shown, it also includes a support wheel 140, which is rotatably connected to the bottom of the first aeration pipe 110, and there are multiple support wheels 140.

[0074] The support wheel 140 can reduce the friction when the first aeration pipe 110 rotates, prevent the first aeration pipe 110 from directly contacting the bottom of the outer casing 100, and reduce the wear rate of the first aeration pipe 110.

[0075] Furthermore, such as Figures 2 to 7 As shown, it also includes an elastic element 160, which is fixed between the support wheels 140. When the rotation speed of the first aeration pipe 110 increases, the elastic element 160 makes the pitch of each part of the first aeration pipe 110 change uniformly, preventing the first aeration pipe 110 from undergoing plastic deformation.

[0076] In one embodiment, such as Figures 2 to 7 As shown, the stirring assembly 200 includes a drive motor 210, a rotating shaft 220, and stirring blades 240.

[0077] The drive motor 210 is fixedly connected to the housing 100. The drive motor 210 can drive the rotating shaft 220 to rotate. The rotating shaft 220 is fixedly connected to the stirring blade 240. The rotation of the rotating shaft 220 drives the stirring blade 240 to stir the material.

[0078] The stirring assembly 200 rotates, and the reduction assembly 300 causes the first aeration pipe 110 to rotate. The reduction assembly 300 makes the rotational speed of the first aeration pipe 110 less than the rotational speed of the stirring assembly 200.

[0079] After the speed of the stirring component 200 is V1 for a first preset time, the speed of the stirring component 200 is adjusted to V2. After the speed of the stirring component 200 is V2 for a second preset time, the speed of the stirring component 200 is adjusted back to V1.

[0080] Intermittently increasing the rotation speed of the first aeration pipe 110 and the stirring component 200 reduces the pitch of the first aeration pipe 110 during rotation, making the bubbles released by the first aeration pipe 110 denser and providing more bubbles for the stirring component 200, thus making the aeration of materials with shallow depth more complete.

[0081] Furthermore, such as Figure 7 As shown, the stirring assembly 200 also includes a rotating disk 250, which is disposed between the rotating shaft 220 and the stirring blade 240. The rotating shaft 220 rotates and drives the stirring blade 240 to rotate through the rotating disk 250.

[0082] Furthermore, such as Figure 8 As shown, the stirring blade 240 has a fixed end 242, a first blade portion 244 and a second blade portion 246. The fixed end 242 is fixedly connected to the rotating disk 250. The first blade portion 244 and the second blade portion 246 are fixedly connected to the fixed end 242. The first blade portion 244 and the second blade portion 246 are arc-shaped plates with arc-shaped cross sections.

[0083] Specifically, the fixed end 242 is connected to the rotating disk 250 by bolts.

[0084] In one embodiment, such as Figures 2 to 15 As shown, it also includes a rotating shaft 220 and a ventilator 150. The deceleration assembly 300 includes a first fixing plate 310, a second fixing plate 320, a fixing ring 330, a fixing shaft 340, and a second gear 350.

[0085] A first gear 230 is provided on the rotating shaft 220. The first gear 230 is fixedly connected to the rotating shaft 220. The rotation of the rotating shaft 220 drives the first gear 230 to rotate.

[0086] One end of the air cylinder 150 is rotatably connected to the air inlet pipe 108, and the other end of the air cylinder 150 is rotatably connected to the fixing ring 330. The air cylinder 150 is connected to the first aeration pipe 110, and the rotation of the air cylinder 150 drives the first aeration pipe 110 to rotate.

[0087] One end of the first fixing plate 310 is fixedly connected to the inner wall of the outer shell 100, and the other end of the first fixing plate 310 is fixedly connected to the fixing ring 330. The fixing ring 330 is disposed between the rotating shaft 220 and the ventilator 150. The second fixing plate 320 is fixedly connected to the inner wall of the fixing ring 330. The fixing shaft 340 is fixed on the second fixing plate 320, and the second gear 350 is rotatably connected to the fixing shaft 340.

[0088] An internal gear 155 is provided on the inner wall of the ventilation cylinder 150.

[0089] The second gear 350 meshes with the first gear 230, and simultaneously meshes with the internal gear 155. The pitch circle diameter of the first gear 230 is smaller than that of the internal gear 155.

[0090] Specifically, one end of the fixing ring 330 is rotatably connected to the rotating shaft 220, and the other end of the fixing ring 330 is rotatably connected to the ventilator 150.

[0091] During use, the rotating shaft 220 rotates, driving the first gear 230 to rotate. The first gear 230 rotates, driving the second gear 350 to rotate. The second gear 350 rotates, driving the inner gear 155 to rotate. The inner gear 155 rotates, causing the air cylinder 150 to rotate. The air cylinder 150 rotates, driving the first aeration pipe 110 to rotate.

[0092] The speed reduction effect of the speed reduction component 300 makes the rotational speed of the first aeration pipe 110 less than the rotational speed of the rotating shaft 220.

[0093] In one embodiment, such as Figures 2 to 15 As shown, it also includes a second aeration pipe 120 and a guide plate 170.

[0094] The second aeration pipe 120 is fixed to the bottom of the outer shell 100, and the second aeration pipe 120 is connected to the air inlet pipe 108.

[0095] The second aeration pipe 120 is provided with a second aeration hole 125, which is set at an angle downward. Air in the air inlet pipe 108 enters the second aeration pipe 120, and air in the second aeration pipe 120 is discharged into the aeration chamber 102 through the second aeration hole 125.

[0096] The guide plate 170 is inclinedly disposed on the inner wall of the outer shell 100. The inclination angle of the guide plate 170 can be adjusted. The guide plate 170 is disposed above the second aeration hole 125, so that the bubbles discharged from the second aeration hole 125 are guided to the stirring component 200, making the aeration of the material more uniform.

[0097] Specifically, the second aeration pipe 120 is disposed on the outer wall of the bottom of the outer casing 100. A first mounting groove is provided on the outer wall of the bottom of the outer casing 100. The second aeration pipe 120 is fixed in the first mounting groove.
