Description

Technical Field

[0001] The utility model relates to the technical field of river engineering, and in particular to a sediment treatment device for urban river hydrological engineering. Background Art

[0002] Hydrological engineering mainly studies the basic knowledge and skills of hydrology, water resources and water environment, involving the evaluation of groundwater resources, water resource development and utilization, water resource protection and management, and the prevention and control of water resource problems. Urban rivers refer to the routes through which rivers flow, usually referring to navigable waterways. They are necessary elements for the survival and development of cities and play a very important role in the economic development and ecological protection of cities and surrounding areas. Therefore, in order to protect the water environment of rivers, it is necessary to regularly clean up the silt in the rivers and treat them.

[0003] The existing patent publication number CN216825221U discloses a sediment treatment device for urban river engineering, including a packing tank, which consists of a sediment chamber and a stone chamber. The outer wall of the top of the packing tank is fixedly connected to two symmetrically arranged connecting boxes, the interior of one of the two connecting boxes is fixedly connected to a guide rod, and the interior of the other of the two connecting boxes is rotatably connected to a threaded rod, one end of the threaded rod is fixedly connected to a driving motor, and the driving motor is fixedly connected to the outside of the connecting box, and support frames are provided on the outsides of the threaded rod and the guide rod. The top of the support frame is fixedly connected to a cross plate by screws, and a separation barrel is provided at the bottom of the cross plate. The middle part of the top of the cross plate is fixedly connected to a rotating motor, and the interiors of both ends of the cross plate are fixedly connected to connecting rods, and the output end of the rotating motor is fixedly connected to a rotating shaft. This utility model sediment treatment device for urban river engineering improves the efficiency of sediment treatment and reduces the time for picking stones in the later stage.

[0004] The above scheme has the following problems during implementation: the device is provided with a conical disc to filter and separate the sediment, but the device is provided with only one set of conical discs, so there is only one size of filter aperture. In this way, when filtering sediment, the aperture of the conical disc is large, which easily causes smaller stones to fall out of the filter holes of the conical disc, making the stones not filtered cleanly enough, affecting subsequent processing. If the aperture of the conical disc is small, more stones will be intercepted and accumulated on the surface, which is easy to affect the filtering effect and greatly reduce the practicality of the device. For this reason, we provide a sediment treatment device for urban river hydrological engineering to solve the above problems. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] like Figure 1 、 Figure 2 and Figure 4As shown, the utility model provides a technical solution: a sediment treatment device for urban river hydrological engineering, comprising a sub-packaging pool 1 and a separation barrel 2, a support frame 21 is provided on the lower side of the outer wall of the separation barrel 2, the sub-packaging pool 1 is arranged on the inner side of the support frame 21, a discharge hopper 22 is installed at the bottom end of the separation barrel 2, a discharge port 23 is provided at the side end of the separation barrel 2, a discharge assembly 3 for discharging sediment is provided at the top of the separation barrel 2, the discharge assembly 3 comprises a feed barrel 31 and a motor 33, the feed barrel 31 is installed at the top end of the separation barrel 2, and the feed barrel 32 is provided at the bottom end of the separation barrel 2. A lower hopper 32 is installed at the top of 31, and a motor 33 is installed on the side of the top of the separation barrel 2 close to the distribution barrel 31. The output end of the motor 33 passes through the outer wall of the distribution barrel 31 and is connected to a rotating roller 34. The surface of the rotating roller 34 is equidistantly connected with a partition plate 35. This structure drives the rotating roller 34 to rotate by starting the motor 33, and the rotating roller 34 drives the partition plate 35 to rotate. In this way, the mud and sand in the lower hopper 32 can be sent into the separation barrel 2 little by little, so that a small amount of continuous filtration can be carried out, making it less likely to be blocked during filtration.

[0030] As an implementation method in this embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, the interior of the separation barrel 2 is provided with several groups of filter assemblies 4 for filtering and separating sediment, and several groups of filter assemblies 4 are arranged in the separation barrel 2 at equal intervals in the longitudinal direction. Each group of filter assemblies 4 includes several groups of fixed blocks 41, and several groups of fixed blocks 41 are fixedly connected to the inner wall of the separation barrel 2. A fixed rod 42 is installed on the top of each group of fixed blocks 41, and a movable groove 43 is opened on the top of each group of fixed rods 42. A movable rod 44 is slidably installed in each group of movable grooves 43, and a spring 4 is sleeved on the surface of each group of movable rods 44. 5, and the springs 45 are all arranged in the movable grooves 43, and the top ends of the plurality of groups of movable rods 44 are installed with filter screens 46, and the apertures of the plurality of groups of filter screens 46 decrease from top to bottom. This structure allows the sediment to fall on the uppermost filter screen 46 for filtration, and after filtration, it will fall on the next group of filter screens 46 for filtration again, and so on, so that the sediment can be filtered multiple times, and the filter screens 46 with different apertures can be used to filter stones of different sizes, making the filtration cleaner and not easy to cause the accumulation of stones to affect the filtration.

[0031] It should be noted that several groups of filter screens 46 are all inclined, and the end of the filter screen 46 close to the discharge port 23 is lower than the end away from the discharge port 23, so that the stones filtered and intercepted by the filter screen 46 can slide to the discharge port 23 and accumulate. When the discharge port 23 is opened, the stones will fall out of the separation barrel 2.

[0032] As an implementation method in this embodiment, Figure 4As shown, the bottom end of the upper filter screen 46 is fixedly connected to a connecting rod 47, and the bottom end of the connecting rod 47 passes through several groups of filter screens 46 on the lower side and is connected to a connecting block 48. Several groups of filter screens 46 are fixedly connected to the connecting rod 47, so that several groups of filter screens 46 can be connected together, and the knocking assembly 5 is arranged on the lower side of the connecting block 48, so that the contact area can be increased. A knocking assembly 5 for increasing the filtering effect of the filter assembly 4 is provided on the lower side of the separation barrel 2, and the knocking assembly 5 includes a motor 2 51, and the motor 2 51 is installed on the outer wall of the separation barrel 2. A rotating rod 52 is installed at the output end of the motor 2 51, and the rotating rod 52 extends from one end of the motor 2 51 to the interior of the separation barrel 2 and is connected to the cam 53, and the cam 53 is provided on the connecting block On the lower side of 48, the structure enables motor 2 51 to drive the rotating rod 52 to rotate, and the rotating rod 52 drives the cam 53 to rotate. The cam 53 will intermittently knock the connecting block 48 and lift it up, and the connecting block 48 drives the connecting rod 47 to move upward, and the connecting rod 47 drives several groups of filter screens 46 to move upward. At this time, the filter screen 46 will drive several groups of movable rods 44 to slide in the movable groove 43 and compress the spring 45. When the cam 53 is away from the connecting block 48, the restoring force of the spring 45 will push the movable rod 44 downward to drive the filter screen 46, so that the filter screen 46 is reset, thereby driving the filter screen 46 to move back and forth up and down, and the filter screen 46 vibrates, thereby increasing the filtration efficiency of the filter screen 46, greatly increasing the practicality of the device.

[0033] As an implementation method in this embodiment, Figure 5 As shown, a sealing assembly 6 for blocking the discharge port 23 is provided at one end of the separation barrel 2 near the discharge port 23, and the sealing assembly 6 includes a support rod 61, which is installed at one end of the separation barrel 2 near the discharge port 23, and a cylinder 62 is installed at the end of the support rod 61 away from the separation barrel 2, and the output end of the cylinder 62 passes through the support rod 61 and is installed with a door panel 63, which is inserted into the discharge port 23. This structure enables the cylinder 62 to be started to drive the door panel 63 to move out of the discharge port 23, so that the discharge port 23 can be opened, and the filtered stones will fall into another group of slots in the filling tank 1 for storage, and a guide hopper 24 is installed on the lower side of the end of the separation barrel 2 near the discharge port 23, so that the stones can fall into the other group of slots in the filling tank 1 more accurately.

[0034] Working principle: If you need to filter and separate the sediment, you only need to transport the sediment to be processed into the lower hopper 32, and at the same time start the motor 33 to drive the rotating roller 34 to rotate, and the rotating roller 34 drives the partition plate 35 to rotate, so that the sediment in the lower hopper 32 can be sent into the separation barrel 2 little by little, and then the sediment will fall on the uppermost filter screen 46 for filtration. After filtration, it will fall to the next set of filter screens 46 for filtration again, and so on. In this way, the sediment can be filtered multiple times, and filter screens 46 with different pore sizes can be used to filter stones of different sizes, making the filtration cleaner and not easily causing stone accumulation to affect the filtration. After filtration, the sediment will fall from the discharge hopper 22 into one of the slots in the sub-packaging tank 1 for storage.

[0035] At the same time, the second motor 51 is started to drive the rotating rod 52 to rotate, and the rotating rod 52 drives the cam 53 to rotate. The cam 53 will intermittently knock the connecting block 48 and lift it up. The connecting block 48 drives the connecting rod 47 to move upward, and the connecting rod 47 drives several groups of filter screens 46 to move upward. At this time, the filter screen 46 will drive several groups of movable rods 44 to slide in the movable groove 43 and compress the spring 45. When the cam 53 moves away from the connecting block 48, the restoring force of the spring 45 will push the movable rod 44 downward to drive the filter screen 46, so that the filter screen 46 is reset, thereby driving the filter screen 46 to move back and forth up and down, causing the filter screen 46 to vibrate, thereby increasing the filtration efficiency of the filter screen 46, thereby greatly increasing the practicality of the device;

[0036] Finally, the filtered and intercepted stones will accumulate on several groups of filter screens 46. At this time, the cylinder 62 is started again to drive the door panel 63 to move out of the discharge port 23, and the discharge port 23 can be opened. The filtered stones will fall into another group of slots in the sub-packaging tank 1 for storage, so that the stones in the mud and sand can be filtered, separated and stored separately without moving the separation barrel 2, making the subsequent mud and sand processing more convenient, greatly increasing the convenience of the device.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
