A separation mechanism, a feeding mechanism, and a cleaning mechanism are arranged on the treatment tank. In the present invention, the separation mechanism is connected to the treatment tank, and the auger in the separation mechanism is in transmission connection with the motor in the cleaning mechanism. When using this device, the sewage to be separated is discharged into the separation tank through the feeding mechanism. At this time, the sewage flows out through a plurality of leakage holes on the bottom surface of the separation tank, and the sludge remaining in the separation tank is conveyed to the right side of the separation tank through the rotation of the auger driven by the motor and discharged through the feeding port, so as to filter and separate the large-volume sludge particles in the sewage by using the separation mechanism.

[0012] Preferably, the shape of the limiting groove is an annular wave structure.

[0013] Preferably, the impact mechanism includes a moving ring slidably connected to the moving rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting structures such as a transmission mechanism, a moving rod, and an impact mechanism, the present invention enables multiple moving rods to perform circular movement in a wave-like trajectory, controls the impact mechanism to repeatedly impact the inner cylinder, causing the inner cylinder to vibrate, so as to facilitate shaking off the mud and slag blocking the water outlet pipe, enabling the device to be used for a long time without frequently disassembling the inner cylinder for cleaning and unclogging. At the same time, the meshing transmission between the second gear teeth, the spur gear, and the first gear teeth is utilized to enable the moving rod to move at a slower speed, avoiding deformation and even breakage of the moving rod. The impact mechanism uses the rectangular sliding plate to slide in the chute so that the concave grinding rod on the impact mechanism always faces the inner cylinder to facilitate impact on it. In addition, by setting a spring, the reverse impact force of the inner cylinder on the impact mechanism can be reduced, the service life of the impact mechanism can be prolonged, and at the same time, the space utilization rate can be improved and the cost can be saved.

[0021] 2. By setting structures such as an inclined elliptical ring groove and a multi-section elastic telescopic rod, while the moving rod is moving, it also forces the impact mechanism to move up and down, hitting the inner cylinder and multiple discharge mechanisms thereon with a smaller number, thereby reducing the use of the impact mechanism and saving the working cost to a certain extent. In addition, by setting the discharge mechanism, it is easy for the mud and slag to enter the water outlet pipe but difficult to leave, while the water can leave by its own fluidity. Then, the impact of the impact mechanism is used to discharge the mud and slag in the water outlet pipe along a parabola into the inner cylinder, avoiding the mud and slag from sliding into the other conical pipes below.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Embodiment 1

[0035] As Figure 1-6As shown, this embodiment discloses a mud-water separation device for low-carbon source sewage treatment, including an outer cylinder 1, a transmission mechanism 6 is provided on the upper part of the inner surface of the outer cylinder 1, and the driving force of the motor 3 is utilized through the transmission mechanism 6 to control multiple moving rods 7 to move in a circular trajectory at a slower speed. The inner cavity bottom wall of the outer cylinder 1 is provided with an inner cylinder 10, and the mud and water injected into the inner cylinder 10 are centrifugally separated by controlling the inner cylinder 10 to rotate rapidly, so that the water passes through the inner cylinder 10 into the outer cylinder 1 and is discharged, while the mud stays in the inner cylinder 10. When the work is completed or the inner cylinder 10 is almost full of mud, it is discharged once again. The inner surface of the inner cylinder 10 is evenly provided with a plurality of through holes 1 penetrating its outer surface, and the inner surface of the plurality of through holes 1 Each of them is provided with a discharge mechanism 20 for removing mud by vibration. Simply reducing the through hole 1 is indeed conducive to the separation of mud and water, so that the mud stays in the inner cylinder 10, but it is also easy to cause the through hole 1 to be blocked, so a discharge mechanism 20 is set here to facilitate the removal of silt in the through hole 1. The bottom wall of the inner cavity of the outer cylinder 1 is provided with a mud outlet groove 14 that runs through its lower end and communicates with the inner cavity of the inner cylinder 10, and the diameter of the mud outlet groove 14 is equal to the inner diameter of the inner cylinder 10, so as to remove the mud residue in the inner cylinder 10 and reduce the residue. The inside of the mud outlet groove 14 is provided with a sealing plug 13. The bottom wall of the inner cavity of the outer cylinder 1 is provided with two water outlet grooves 11 that run through its lower end, and the lower end of the outer cylinder 1 is provided with two drainage pipes 12 that are respectively communicated with the two water outlet grooves 11;

[0036] It can be concluded that the motor 3 controls the inner cylinder 10 to rotate at a high speed, centrifugally separates the muddy water injected into the inner cylinder 10, and makes the water flow into the outer cylinder 1 through the discharge mechanism 20, and finally discharges through the water outlet trough 11 and the drain pipe 12, while the mud residue is intercepted in the inner cylinder 10. When the work is finished or the inner cylinder 10 is almost full of mud, the mud residue is taken out from the mud outlet trough 14 by opening the sealing plug 13, thereby realizing the fine separation of muddy water;

[0037] For details, please refer to Figure 2-3 , four legs 5 are evenly arranged at the lower end of the outer cylinder 1, a cover 2 is arranged at the upper end of the outer cylinder 1, a motor 3 is arranged at the middle part of the upper end of the cover 2, a transmission rod 31 penetrating the transmission mechanism 6 is arranged at the output end of the motor 3 through a coupling, the transmission rod 31 passes through the top plate 61 and is rotatably connected to the top plate 61, the lower end of the transmission rod 31 extends to the inner cavity of the inner cylinder 10 and is provided with a plurality of connecting rods 34 together with its inner surface, that is, the top of the inner cylinder 10 is in an open state, which is convenient for continuously injecting muddy water into the inner cylinder 10, thereby improving work efficiency, a feed pipe 4 communicating with the inner cylinder 10 is arranged at the upper end of the cover 2, and the feed pipe 4 is made of a relatively strong material, which is convenient for fixing the top plate 61;

[0038] Specifically, the lower end of the feed pipe 4 penetrates through the cover 2 and the transmission mechanism 6 and extends into the interior of the inner cylinder 10. The feed pipe 4 penetrates through the top plate 61 and is fixed to the top plate 61. The lower end surface of the feed pipe 4 is located above the first connecting rod 34 and does not contact it, preventing the first connecting rod 34 from colliding with the feed pipe 4 and affecting each other.

[0039] Specifically, please refer to Figure 4 To prevent the moving rod 7 from deforming or even breaking due to excessive rotation speed, in this embodiment, the transmission mechanism 6 is provided to include a top plate 61 fixedly connected to the upper part of the inner surface of the outer cylinder 1 and a transmission ring 62 rotatably connected to the top plate 61. A number of second gear teeth 67 are evenly provided on the inner surface of the transmission ring 62. Two rotating rods 63 rotatably connected to the bottom of the cover 2 are provided at the upper end of the top plate 61. Straight gears 64 for changing the rotation speed and meshing with a number of second gear teeth 67 are provided on the outer surfaces of the two rotating rods 63. A number of first gear teeth 32 respectively meshing with the two straight gears 64 are provided on the lower part of the outer surface of the transmission rod 31. The number of teeth on the straight gear 64 is greater than the number of teeth on the first gear tooth 32 to facilitate reducing the transmitted speed.

[0040] The principle of using the meshing of large and small gears to change the transmitted rotational speed is utilized to reduce the rotational speed of the transmission ring 62, increase the torque, facilitate driving the moving rod 7 to move along a predetermined trajectory, and control the impact mechanism 81 to impact the inner cylinder 10.

[0041] Specifically, a number of sliding grooves 65 are evenly formed on the outer side of the lower end of the transmission ring 62. The shape of the sliding groove 65 is a T-shaped structure, which is convenient for hanging the moving rod 7 equipped with a rectangular sliding plate 71 to prevent the moving rod 7 from directly falling. A limiting groove 66 penetrating through its lower end is formed on the outer side of the upper end of the top plate 61. A number of moving rods 7 are evenly provided on the inner surface of the limiting groove 66. The upper parts of the number of moving rods 7 all pass through the limiting groove 66 and extend into the interiors of a number of sliding grooves 65 on the same side respectively. A rectangular sliding plate 71 slidably connected to the inside of the sliding groove 65 is provided at the upper end of the moving rod 7. The part where the rectangular sliding plate 71 is slidably connected to the sliding groove 65 is convenient for hanging the moving rod 7. An impact mechanism 81 for vibrating and discharging the slurry in the discharging mechanism 20 is provided on the outer surface of the moving rod 7. The impact mechanism 81 repeatedly impacts the inner cylinder 10 to generate vibration, thereby facilitating the vibration and falling of the mud slag entering the conical pipe 205.

[0042] Specifically, the horizontal height of the lower end of the moving rod 7 is lower than the horizontal height of the lowest point of the inclined elliptical ring groove 15, and the lower end of the moving rod 7 does not contact the inner cavity bottom wall of the outer cylinder 1. On the one hand, it is convenient for sleeving the impact mechanism 81 on the moving rod 7, and on the other hand, it prevents it from directly detaching from the lower part of the moving rod 7 during operation without external force.

[0043] Further, the shape of the limiting groove 66 is an annular wavy structure, that is, there are multiple inflection points on the limiting groove 66. When the moving rod 7 moves to the inflection point on the outer side of the limiting groove 66, the impact mechanism 81 moves away from the inner cylinder 10. When the moving rod 7 moves to the inflection point on the inner side of the limiting groove 66, the impact mechanism 81 approaches the inner cylinder 10 and impacts the inner cylinder 10, causing the inner cylinder 10 to vibrate. Then, through repeated impacts, the vibration of the inner cylinder 10 is increased to facilitate the vibration of the mud residue in the conical pipe 205 and the water outlet pipe 206.

[0044] Further, please refer to Figure 6 , the impact mechanism 81 includes a moving ring 811 slidably connected to the moving rod 7. The moving ring 811 cannot rotate by itself without external force, and the moving rod 7 can only move along a circular track following the transmission ring 62 due to the rubber strip 82 and the rectangular slide plate 71. Thus, the end of the concave grinding rod 814 away from the moving ring 811 always faces the inner cylinder 10. On one side of the outer surface of the moving ring 811 close to the inner cylinder 10, there is a connecting rod two 812. At the end of the connecting rod two 812 close to the inner cylinder 10, there is a convex rod 813. On the outer surface of the protruding part of the convex rod 813, there is a concave grinding rod 814. Between the end of the protruding part of the convex rod 813 close to the inner cylinder 10 and the side wall of the concave part of the concave grinding rod 814 close to the inner cylinder 10, there is a spring 815 in common. The spring 815 is used to slow down the reverse impact force of the inner cylinder 10 on the impact mechanism 81, extend the service life of the impact mechanism 81, improve the space utilization rate, and save costs;

[0045] Further, the end face of the concave grinding rod 814 close to the inner cylinder 10 is an arc structure with the same radian as the outer surface of the inner cylinder 10, which expands the impact area, reduces the pressure, and avoids damaging the inner cylinder 10 due to repeated impacts, thereby extending the service life of the inner cylinder 10.

[0046] Therefore, the specific implementation manner of this embodiment is:

[0047] The motor 3 controls the high-speed rotation of the inner cylinder 10 through the transmission rod 31 and the first connecting rod 34, centrifugally separates the muddy water injected into the inner cylinder 10, enables the water to flow into the outer cylinder 1 through the discharge mechanism 20, and finally discharges it through the water outlet groove 11 and the drain pipe 12. During this process, the transmission rod 31 drives two meshing spur gears 64 to rotate through a plurality of first teeth 32 on its outer surface. Then, the two spur gears 64 rotating in the same direction drive the transmission ring 62 to rotate at a slower speed through a plurality of second teeth 67. After that, the transmission ring 62 drives the moving rod 7 to move. When the moving rod 7 moves, it is restricted and guided by the limiting groove 66, causing the moving rod 7 to perform an annular movement along a wavy trajectory, driving the impact mechanism 81 to flip and impact the inner cylinder 10, causing the inner cylinder 10 to vibrate and forcing the mud residue to fall back into the inner cylinder 10. When the work is completed or the inner cylinder 10 is about to be filled with mud, the mud residue is taken out from the mud outlet groove 14 by opening the plug 13.

[0048] Embodiment 2

[0049] Based on Embodiment 1, this embodiment adds a discharge mechanism 20 to the inner cylinder 10 to facilitate reducing the mud residue in the conical pipe 205 and the water outlet pipe 206 and reducing the probability of the discharge mechanism 20 being blocked. As Figure 7-10 shown, in order to reduce the use of the impact mechanism 81 and enable the impact mechanism 81 to impact multiple discharge mechanisms 20, an inclined elliptical ring groove 15 is formed on the inner surface of the outer cylinder 1 in this embodiment. By using the inclined elliptical ring groove 15, when the moving rod 7 moves, it forces the impact mechanism 81 to move up and down on the moving rod 7, impacting the inner cylinder 10 and the discharge mechanism 20 thereon. A multi-joint elastic telescopic rod 9 slidably connected to the inside of the inclined elliptical ring groove 15 is provided on one side of the outer surface of one moving ring 811 away from the inner cylinder 10, so that no matter whether the moving rod 7 moves outward or inward from the top plate 61, the thicker part of the multi-joint elastic telescopic rod 9 is always slidably connected to the inclined elliptical ring groove 15. A rubber strip 82 is commonly provided between the outer surfaces of adjacent two moving rings 811. The rubber strip 82 has a certain elasticity and ductility, facilitating dragging multiple impact mechanisms 81 to move up and down together without affecting the outward movement between multiple impact mechanisms 81;

[0050] Specifically, please refer to Figure 8-9, the discharge mechanism 20 includes a rubber ring 201 fixedly connected to the inner surface of the first through hole. The outer diameter of the rubber ring 201 is larger than the diameter of the concave grinding rod 814, so that the rubber ring 201 is more likely to be impacted by the concave grinding rod 814. A second through hole 202 penetrating the middle of its inner surface is provided in the middle of the outer surface of the rubber ring 201. Two positioning rods 203 are provided on the inner surface of the second through hole 202. A limiting ring 204 is jointly provided at one end of the two positioning rods 203 close to each other, so that the water outlet pipe 206 always maintains a horizontal state. The water outlet pipe 206 is provided on the inner surface of the limiting ring 204. One end of the water outlet pipe 206 close to the outer cylinder 1 extends to the outside of the rubber ring 201, which is convenient to impact the water outlet pipe 206 to compress it, squeeze the air inside it, and squeeze the mud residue out of the water outlet pipe 206. A conical pipe 205 fixedly connected to the inner surface of the second through hole 202 is provided at one end of the water outlet pipe 206 away from the outer cylinder 1, so that the mud residue is easy to enter the water outlet pipe 206, but difficult to leave, while the water leaves by its own fluidity;

[0051] Further, the water outlet pipe 206 is made of flexible rubber material, so that it is easier to recover after being compressed and deformed. One end of the conical pipe 205 away from the outer cylinder 1 and one end of the rubber ring 201 away from the outer cylinder 1 are on the same vertical line. When the rubber ring 201 and the water outlet pipe 206 are simultaneously impacted by the impact mechanism 81, the rubber ring 201 will be recessed in the direction away from the outer cylinder 1, so that the conical pipe 205 penetrates into the inner side of the discharge mechanism 20, thereby preventing the mud residue ejected from the water outlet pipe 206 from sliding down along the inner surface of the discharge mechanism 20 into the remaining conical pipes 205 below.

[0052] Therefore, the specific implementation manner of this embodiment is:

[0053] While the transmission ring 62 drives the moving rod 7 to move and controls the impact mechanism 81 to impact the discharge mechanism 20, it will also use the sliding of the multi-section elastic telescopic rod 9 in the inclined elliptical ring groove 15 and the mutual pulling of the multiple rubber strips 82 to make the multiple impact mechanisms 81 move up and down together to impact the multiple discharge mechanisms 20. When the rubber ring 201 and the water outlet pipe 206 are impacted, the rubber ring 201 will be recessed in the direction away from the outer cylinder 1, so that the conical pipe 205 penetrates into the inner side of the discharge mechanism 20, and the water outlet pipe 206 will be impacted by the impact mechanism 81 to be compressed, squeezing the air in the water outlet pipe 206, so that the compressed air squeezes the mud residue out of the water outlet pipe 206 and the conical pipe 205, and drops back into the discharge mechanism 20 along a parabolic trajectory, thereby preventing the mud residue from sliding down along the inner surface of the discharge mechanism 20 into the remaining conical pipes 205 below.
