Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a sediment recovery device. Background Technology

[0002] The washing and processing of konjac generates a large amount of wastewater, which mainly contains pollutants such as konjac fragments, starch, sugars, proteins, waste acids, and waste alkalis. If this wastewater is discharged directly without treatment, the organic matter in it will rapidly deplete dissolved oxygen in the water, causing oxygen deficiency and affecting the survival of fish and other aquatic animals. Simultaneously, suspended solids in the wastewater easily decompose under anaerobic conditions, producing foul odors and worsening water quality. In wastewater treatment, sedimentation tanks are used to settle the wastewater. Furthermore, the sediment can be recycled and sold as pig feed, thus increasing revenue and reducing waste.

[0003] However, when cleaning sediment in a sedimentation tank, the water is usually drained before cleaning, which disrupts the normal operation of the production line. The discharged wastewater has nowhere to be disposed of, and building a new sedimentation tank would increase land area and costs. Furthermore, using other cleaning devices to remove sediment from the bottom of the water body can stir up the previously settled material to the surface, requiring the wastewater to settle again and prolonging the settling time. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a sediment recovery device that solves the problem that cleaning sediment from the bottom of a sedimentation tank causes turbidity in the water and increases the sedimentation time.

[0005] According to an embodiment of the present invention, a sediment recovery device includes a frame, a shovel, a transport assembly, a push assembly, and a drainage assembly. A waterproof third motor is fixedly installed at the bottom of the frame, and a moving unit is installed at the bottom of the frame. The output shaft of the third motor is connected to the moving unit. The shovel is a flat plate structure and is fixedly and obliquely to the top of the frame. The side of the oblique surface of the shovel near the bottom is on the same horizontal plane as the bottommost position of the moving unit. Baffles are vertically installed on the left and right sides of the top surface of the shovel. The push assembly is respectively disposed on both sides of the shovel and pushes the sediment at the top of the shovel upward by moving along the side of the shovel. The transport assembly is disposed on the frame and located on the side of the shovel near the top. The transport assembly moves the sediment that has moved to the top of the shovel to the outside of the water body. The drainage assembly is fixedly connected to the transport assembly so that the liquid is filtered through the transport assembly before being discharged.

[0006] The technical principle of this invention is as follows: When this invention moves at the bottom of the sedimentation tank, the sediment is scooped up by the shovel plate. With the help of the pushing component, the sediment moves upward to the shovel plate. This process does not involve violent movement. The sediment is transported upward to the outside of the water body by the transport component. The turbid water caused during the discharge process is filtered by the drainage component, thereby avoiding or reducing the problem of turbidity in the sedimentation tank when transferring sediment.

[0007] Preferably, the pushing assembly includes a first push plate, a second push plate, a main telescopic rod, a secondary telescopic rod, and a sliding plate. The sliding plate has a planar structure, and the sliding plate and the baffle are parallel, attached, and slidably connected. The sliding plate is located on the side of the baffle closer to the shovel plate. The first and second push plates are perpendicular to the shovel plate and contact the top surface of the shovel plate. The sides of the first and second push plates are slidably connected to the sliding plate, with a gap between the two slidably connected positions. The sides of the first and second push plates away from the sliding plate are rotatably connected. The main telescopic rod is parallel to and fixedly connected to the side of the baffle away from the shovel plate. The movable section of the main telescopic rod is fixedly connected to the sliding plate above the baffle. The secondary telescopic rod is perpendicular to the sliding plate and is located on the side of the sliding plate away from the shovel plate. The secondary telescopic rod and the sliding plate are fixedly connected by a connecting frame. The movable end of the secondary telescopic rod is connected to the rotation axis of the first and second push plates above the baffle.

[0008] Preferably, the transport assembly includes a first motor, a screw rod, a housing, and a hopper. The screw rod is vertically mounted on the frame and located on the side of the shovel plate near the top. The first motor is fixedly connected to the frame, and the output shaft of the first motor is coaxial with and connected to the screw rod. The housing is a cylindrical housing, coaxial with the screw rod, and its bottom is fixedly connected to the frame. The housing has a feed inlet at the position corresponding to the shovel plate. The top of the housing has a discharge outlet, and a hopper is fixedly mounted at the position of the discharge outlet. A switch is mounted at the bottom of the hopper. A base plate is horizontally mounted at the bottom of the screw plate, and the base plate is connected to the shovel plate.

[0009] Preferably, the drainage assembly includes a drain pipe, a filter screen, an impeller, and a second motor. One end of the drain pipe is fixedly connected to and communicates with the bottom of the housing, and the other end of the drain pipe is curved upwards. The filter screen is disposed at the connection between the drain pipe and the housing. The impeller is coaxial with and rotatably disposed inside the drain pipe. The second motor is fixedly disposed inside the drain pipe and is coaxial with and connected to the impeller.

[0010] Preferably, the moving unit includes a plurality of rollers or tracks arranged on the left and right.

[0011] Preferably, a support frame is provided at the bottom of the hopper, and the bottom of the support frame is fixedly connected to the vehicle frame.

[0012] Preferably, the vehicle frame is equipped with an automatic driving system.

[0013] Preferably, a funnel-shaped guide plate is provided at the feed inlet.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When using this invention, there is no device that causes violent movement to separate the sediment from the bottom of the sedimentation tank. The vehicle moves slowly, and the sediment will not be rolled up to the upper layer of water when it is separated from the bottom of the tank. This can effectively clean the sediment in the sedimentation tank.

[0016] 2. Under the mutual compression of the sediment, the sediment moves to the front half above the shovel plate. If it moves upward further, it may cause the sediment to loosen and disperse in the water. This pushes the component to slide up and down on both sides of the shovel plate, clamping the sediment from both sides and then moving the sediment upward, so that the sediment enters the transport component in a stable state.

[0022] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1As shown in the figure, this embodiment of the invention proposes a sediment recovery device, including a frame 4, a shovel 3, a transport component, a push component, and a drainage component. The frame 4 is a frame structure, and a waterproof third motor is installed at the bottom of the frame 4. A moving unit is installed at the bottom of the frame 4, and the output shaft of the third motor is connected to the moving unit to provide power to the moving unit. The shovel 3 is a flat plate structure, and the shovel 3 is made of plastic to prevent rusting. The top surface of the shovel 3 is a smooth surface to avoid excessive resistance when the sediment 2 moves. The shovel 3 is fixed at an angle to the top of the frame 4, and the angle of inclination of the shovel 3 should not be too large to prevent the sediment 2 from being unable to move on the inclined surface. The side of the inclined surface of the shovel 3 near the bottom is at the same horizontal plane as the bottom position of the moving unit. The side of the shovel 3 near the bottom is provided with a wear-resistant layer to prevent damage after a few uses. When this sediment recovery device is placed in the sedimentation tank 1, a gap is provided between the shovel 3 and the bottom of the tank to avoid continuous friction. The top surface of the shovel plate 3 is vertically equipped with baffles 22 on both the left and right sides. The height of the baffles 22 is greater than the thickness of the sediment 2. The thickness of the sediment 2 over a period of time can be estimated to determine the size of the baffles 22. The pushing components are respectively located on both sides of the shovel plate 3. The pushing components move along the side of the shovel plate 3, pushing the sediment 2 on the top of the shovel plate 3 upwards. The transport component is mounted on the frame 4 and located on the upper side of the shovel plate 3. The transport component moves the sediment 2 that has moved to the top of the shovel plate 3 out of the water body. The drainage component and the transport component are fixedly connected, allowing the liquid to be filtered through the transport component before being discharged.

[0024] like Figure 2 , 4As shown, preferably, the pushing assembly includes a first push plate 20, a second push plate 21, a main telescopic rod 18, a secondary telescopic rod 19, and a sliding plate 23. The sliding plate 23 has a planar structure, and the height of the sliding plate 23 is the same as the height of the baffle 22. The sliding plate 23 and the baffle 22 are parallel to each other and slidably connected. The baffle 22 is provided with a concave T-shaped sliding groove, and the sliding plate 23 is provided with a matching T-shaped sliding member. The extension direction of the sliding groove is parallel to the straight line of the side of the shovel plate 3. The first push plate 20 and the second push plate 21 are rectangles of equal width. They are perpendicular to the shovel plate 3 and contact its top surface. The sides of the first push plate 20 and the second push plate 21 are interactively connected to the sliding plate 23, with a gap between the two sliding connection points. The sliding plate 23 has a concave T-shaped sliding groove on the side near the shovel plate 3. The sides of the first push plate 20 and the second push plate 21 are each equipped with a matching T-shaped sliding member. The first push plate 20 and the second push plate 21 are rotatably connected to the T-shaped sliding member. The sides of the first push plate 20 and the second push plate 21 away from the sliding plate 23 are rotatably connected, and a rotating shaft is provided at the rotatable connection point. The main telescopic rod 18 is parallel to and fixedly connected to the side of the shovel plate 3 on the side of the baffle 22 away from the shovel plate 3. The movable section of the main telescopic rod 18 is fixedly connected to the sliding plate 23 above the baffle 22. The auxiliary telescopic rod 19 and the sliding plate 23 are perpendicular and positioned on the side of the sliding plate 23 away from the shovel plate 3. The auxiliary telescopic rod 19 and the sliding plate 23 are fixedly connected by a connecting frame 24. The movable end of the auxiliary telescopic rod 19 is connected to the rotation axis of the first push plate 20 and the second push plate 21 above the baffle 22. When the auxiliary telescopic rod 19 retracts, the first push plate 20 and the second push plate 21 become parallel to each other and fit against the sliding plate 23. When the auxiliary telescopic rod 19 extends, the rotation axis moves away from the sliding plate 23, and the first push plate 20, the second push plate 21, and the sliding plate 23 form a triangle. The connecting edge of the first push plate 20 and the second push plate 21 moves closer to the middle of the shovel plate 3. When the distance between the rotation axes on both sides of the shovel plate 3 decreases, the push plates 21 on both sides will clamp the sediment 2 in the middle, and as the sliding plate 23 moves, it will drive the sediment 2 to move upwards on the shovel plate 3. One side of the connecting frame 24 is fixedly connected to the sliding plate 23, and the other side of the connecting frame 24 is fixedly connected to the fixed section of the auxiliary telescopic rod 19.

[0025] like Figure 1As shown, preferably, the transport assembly includes a first motor 6, a screw rod 7, a housing 8, and a hopper 11. The screw rod 7 is vertically mounted on the frame 4 and located on the side of the shovel plate 3 near the top. The first motor 6 is fixedly connected to the frame 4, and the output shaft of the first motor 6 is coaxial with and connected to the screw rod 7. The housing 8 is a cylindrical housing 8, coaxial with the screw rod 7, and its bottom is fixedly connected to the frame 4. The housing 8 has an inlet 9 at the position corresponding to the shovel plate 3. The top of the housing 8 has an outlet 25, and the hopper 11 is fixedly mounted at the position of the outlet 25. A switch is mounted at the bottom of the hopper 11. A bottom plate is horizontally mounted at the bottom of the screw rod 7, and the bottom plate is connected to the shovel plate 3. When the shovel plate 3 and the pushing assembly continuously transport the sediment 2 to the inlet hopper 11, the sediment 2 will be rotated upwards to the top of the hopper 11 for dust removal. After a certain amount is stored, the sediment recovery device moves to the edge of the sedimentation tank 1 and opens the switch at the bottom of the hopper 11 to discharge the sediment. The discharge pipe at the bottom of the hopper 11 is inclined, allowing the sediment 2 to move laterally a certain distance, avoiding the restriction of the frame 4 by the wall of the sedimentation tank 1, and transferring it to the outside of the wall through the discharge pipe. The hopper 11 is higher than the height of the sedimentation tank 1. In this example, the bottom of the shell 8 can be slightly lower than the side of the shovel plate 3, allowing the sediment 2 to move to the inlet 9 of the shell 8 under the action of gravity. A fixing block 10 is provided on the top of the shell 8, with a round hole on the fixing block 10. The round hole and the top of the screw rod 7 are rotatably engaged, and the fixing block 10 serves as a fixed support.

[0026] like Figure 1 , 3As shown, preferably, the drainage assembly includes a drain pipe 13, a filter screen 16, an impeller 15, and a second motor 14. One end of the drain pipe 13 is fixedly connected to and communicates with the bottom of the housing 8, while the other end of the drain pipe 13 is curved upwards to prevent the discharged water from impacting the bottom of the pool and causing the sediment 2 to float to the water. The filter screen 16 is located at the connection between the drain pipe 13 and the housing 8. When impurities are intercepted by the filter screen 16, they are carried away by the spiral rod 7 and do not accumulate. The impeller 15 is coaxially and rotatably disposed inside the drain pipe 13. The second motor 14 is fixedly disposed inside the drain pipe 13 and is coaxially connected to the impeller 15. The second motor 14 is connected to the second motor 14 via a wire, causing the impeller 15 to rotate continuously, generating suction on the water flow inside the housing 8. This prevents the mixture generated by the rotating rod inside the housing 8 from overflowing from the feed inlet 9 of the housing 8, thus ensuring that the sediment 2 does not diffuse into the water during the transfer of sediment 2. In this example, two fixing rods 26 are installed inside the drain pipe 13, one at the front and one at the back. The fixing rods 26 are perpendicular to and intersect the axis of the drain pipe 13. The ends of the fixing rods 26 are fixedly connected to the inner wall of the drain pipe 13. The rotating shaft of the impeller 15 is rotatably connected to the fixing rods 26, and the rotating shaft of the impeller 15 cannot move axially relative to the fixing rods 26. The second motor 14 is also fixedly connected to the fixing rods 26.

[0027] Preferably, the moving unit includes several rollers 5 or tracks arranged on the left and right. If the sedimentation tank 1 is too smooth and the rollers 5 cannot move normally, the tracks can be used to increase friction so that the present invention can move stably in the sedimentation tank 1.

[0028] Preferably, a support frame 12 is provided at the bottom of the hopper 11. The bottom of the support frame 12 is fixedly connected to the frame 4. When a large amount of sediment 2 is temporarily stored in the hopper 11, the support frame 12 is used to support the hopper 11 to improve the stability of the structure.

[0029] Preferably, the frame 4 is equipped with an automatic driving system. When the sedimentation tank 1 has a large area, the automatic driving system can be used to make the present invention move regularly in the sedimentation tank 1 without repeating the areas that have already been traversed, thereby improving work efficiency.

[0030] Preferably, a funnel-shaped guide plate 17 is provided at the positions of the baffle 22 and the feed inlet 9, so that the sediment 2 can be completely guided into the shell 8, reducing overflow.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
