Description

Technical Field

[0001] The utility model relates to the technical field of silt removal devices, in particular to a silt removal device for a construction river channel. Background Art

[0002] The river management project in water conservancy construction is one of the more complex projects. Before the construction of the river embankment, the water flow in the river needs to be properly cleaned. One of the more important links is to clean up the old sludge, which contains various organic components, microorganisms and domestic impurities. After proper treatment and drying, it can be used as fertilizer to realize waste utilization. The existing dredging process is to use a sludge treatment vehicle for mobile cleaning. The sludge is sucked into the sludge treatment vehicle through a sludge pump for treatment to obtain dry sludge residue. The end of the sludge pump needs to have a filtering device to prevent plant fibers and gravel in the river from entering the sludge pump, resulting in the risk of the sludge pump being scrapped. The filtering equipment needs to be cleaned regularly, especially for rivers with more impurities in the sludge, and the cleaning process requires a lot of man-hours.

[0003] A Chinese utility model patent, publication number CN215562902U, discloses a filtration device for river channel desilting and water conservancy construction. The device comprises a filter tank mounted at the suction end of a slurry pump, a filter screen with a frame mounted on its side, and a filter screen composed of a plurality of horizontal and vertical steel bars arranged in a longitudinal and transverse arrangement. Each of the horizontal and vertical steel bars is secured to a plug plate at the same end, and the frame is provided with slots for receiving the corresponding plug plates. The horizontal and vertical steel bars comprising the filter screen are secured to corresponding plug plates, which engage with the slots. The filter screen is used to filter sludge, filtering out vegetation fibers, plastic bags, rocks, and the like, primarily plastic bags, that may be present in the sludge, to prevent them from entering the slurry pump and causing premature failure.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device blocks impurities such as plant fibers through a filter net. After the filtering equipment has been used for a period of time, the staff needs to manually clean the plant fibers and other impurities wrapped around the horizontal and vertical steel bars. Due to the large number of horizontal and vertical steel bars, the cleaning is difficult and the user experience is poor. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a construction river channel desilting device.

[0006] The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: a construction river dredging device, comprising a mounting plate installed on the suction end of a mud pump, a filter tank connected to the mounting plate, a placement groove being provided on the side wall of the filter tank, a sliding groove being provided on the inner wall of the filter tank, a filter screen being slidably arranged in the sliding groove, a limiting component for limiting the filter screen being provided on the filter tank, a first slide groove being provided on the inner wall of the filter tank, a second slide groove being provided on the inner wall of the first slide groove, and a cleaning component for cleaning the filter screen being provided on the filter tank.

[0007] By adopting this technical solution, when workers need to clean silt from a river channel, they simply place the suction end of the mud pump into the channel and start the mud pump, which then moves the silt out of the channel. At this point, the filter screen blocks impurities such as plant fibers, reducing the chance of them entering the mud pump. After the filter screen has been used for a period of time, workers need to clean it. At this point, workers simply move the filter tank out of the channel and start the cleaning assembly, which then cleans the filter screen, reducing the difficulty of cleaning the filter screen.

[0008] Furthermore, the limiting assembly includes a threaded rod threadedly connected to the side wall of the filter tank and a rubber sheet arranged on the inner wall of the sliding groove.

[0009] By adopting the above technical solution, when workers need to install the filter, they only need to connect the filter to the installation groove and rotate the threaded rod to make the threaded rod press against the filter, thereby making the filter press against the rubber sheet to maintain stability, thereby reducing the difficulty of the workers' operation. Furthermore, workers only need to connect the mounting plate to the upper surface of the filter tank and fix the mounting plate and the filter tank with fixing bolts to secure the mounting plate and the filter tank.

[0010] Furthermore, the cleaning assembly includes a slider slidably arranged in the first sliding groove, a cleaning rod installed on the side wall of the slider, and a cleaning device arranged on the cleaning rod.

[0011] Furthermore, a plurality of cleaning grooves are provided on the side wall of the cleaning rod close to the filter screen, and the cleaning device includes a plurality of cleaning claws which are slidably arranged in the plurality of cleaning grooves in sequence, a return spring at one end fixed to the side wall of the cleaning claw away from the filter screen, and a connecting rope at one end fixed to the side wall of the cleaning claw close to the return spring, the other end of the return spring is fixed to the inner wall of the cleaning groove, and the other end of the connecting rope extends outside the filter pool and is slidably connected.

[0012] Furthermore, the cleaning claws are made of memory alloy.

[0013] Furthermore, a fixing plate is commonly installed on the side walls of the plurality of connecting ropes.

[0014] By adopting the above technical solution, when the staff needs to clean the filter, they only need to slide the slider downward to move the cleaning rod downward, so that the multiple cleaning claws move downward along with the cleaning rod, and the impurities such as plant fibers attached to the side wall of the filter are moved downward under the action of the cleaning claws. Subsequently, when the cleaning claws move to the lowest point, the staff only needs to pull the fixed plate to make the multiple cleaning claws move along with the fixed plate at the same time, and then gradually move the multiple cleaning claws completely into the cleaning groove. During this process, the plant fibers and other impurities hanging on the cleaning claws gradually separate from the cleaning claws. Furthermore, the staff only needs to loosen the fixed plate to reset the multiple cleaning claws, thereby reducing the difficulty of cleaning the filter.

[0015] Furthermore, a third chute is provided at the upper end of the inner wall of the first chute.

[0016] By adopting the above technical solution, when the staff does not need to use the cleaning claw, the staff only needs to slide the slider upwards and pull the cleaning rod to connect the slider and the third slide groove to each other, thereby keeping the cleaning rod stable, thereby improving the staff's usage experience.

[0017] Furthermore, a handle is fixed on the side wall of the fixing plate to reduce the difficulty of workers moving the fixing plate.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. In this application, when the staff needs to clean the silt in the river channel, the staff needs to put the suction end of the mud pump into the river channel and start the mud pump, so that the silt can be moved out of the river channel under the action of the mud pump. At this time, the filter screen blocks impurities such as plant fibers, thereby reducing the probability of impurities such as plant fibers entering the mud pump. When the filter screen has been used for a period of time, the staff needs to clean the filter screen. At this time, the staff only needs to move the filter pool outside the river channel and start the cleaning component, so that the cleaning component can clean the filter screen, thereby reducing the difficulty of the staff in cleaning the filter screen;

[0020] 2. In this application, when the staff needs to install the filter, they only need to connect the filter with the installation groove and rotate the threaded rod to make the threaded rod press against the filter, thereby making the filter press against the rubber sheet to maintain stability, thereby reducing the difficulty of the staff's operation. Furthermore, the staff only needs to connect the mounting plate with the upper surface of the filter tank and fix the mounting plate and the filter tank with fixing bolts;

[0021] 3. In the present application, when the staff needs to clean the filter, the staff only needs to slide the slider downward to move the cleaning rod downward, so that the multiple cleaning claws follow the cleaning rod to move downward, so that the plant fibers and other impurities attached to the side wall of the filter are moved downward under the action of the cleaning claws. Subsequently, when the cleaning claw moves to the lowest point, the staff only needs to pull the fixed plate to make the multiple cleaning claws move with the fixed plate at the same time, and then the multiple cleaning claws are gradually moved completely into the cleaning tank. In this process, the plant fibers and other impurities hanging on the cleaning claws are gradually separated from the cleaning claws. Furthermore, the staff only needs to move the filter tank outside the river channel and start the cleaning component to enable the cleaning component to clean the filter, thereby reducing the difficulty of the staff in cleaning the filter.

[0029] like Figure 1-5As shown, the embodiment of the present application discloses a construction river dredging device, including a filter tank 1, a mounting plate 12, a filter screen 21, a limit assembly 3, a cleaning assembly 4, a fixing plate 6 and a handle 8. The mounting plate 12 is a plate-like structure, and the mounting plate 12 is fixed to the suction end of the mud pump. The filter tank 1 and the mounting plate 12 are interconnected, and a placement groove 11 is provided on the side wall of the filter tank 1, and a sliding groove 2 is provided on the inner wall of the filter tank 1. The filter screen 21 is slidably arranged in the sliding groove 2, and is used to filter impurities such as plant fibers (the aperture of the filter screen can pass through the silt).

[0030] The limiting assembly 3 is provided on the filter tank 1 for limiting the position of the filter screen 21. The limiting assembly 3 includes a threaded rod 31 and a rubber sheet 32. The threaded rod 31 is threadedly connected to the side wall of the filter tank 1. The rubber sheet 32 ​​is a sheet-like structure and is provided on the inner wall of the sliding groove 2.

[0031] When the operator needs to install the filter screen 21, the operator only needs to connect the filter screen 21 with the placement groove 11 and rotate the threaded rod 31 to make the threaded rod 31 press against the filter screen 21, thereby making the filter screen 21 press against the rubber sheet 32 ​​to maintain stability, thereby reducing the operator's operating difficulty. Furthermore, the operator only needs to connect the mounting plate 12 with the upper surface of the filter tank 1 and fix the mounting plate 12 to the filter tank 1 with the fixing bolts.

[0032] A first chute 33 is defined on the inner wall of the receiving tank 11, and a second chute 34 is defined on the inner wall of the first chute 33. A cleaning assembly 4 is disposed on the filter tank 1 for cleaning the filter screen 21. The cleaning assembly 4 includes a slider 41, a cleaning rod 42, and a cleaning device 5. The slider 41 is a rectangular block structure and is slidably disposed within the first chute 33. The cleaning rod 42 is a rectangular rod structure and is mounted on the side wall of the slider 41.

[0033] A plurality of cleaning grooves 43 are provided on the side wall of the cleaning rod 42 near the filter screen 21. The cleaning device 5 is arranged on the cleaning rod 42. The cleaning device 5 includes a cleaning claw 51, a return spring 52 and a connecting rope 53. There are multiple cleaning claws 51 and they are slidably arranged in the multiple cleaning grooves 43 in sequence. The cleaning claws 51 are made of memory alloy. One end of the return spring 52 is fixed to the side wall of the cleaning claw 51 away from the filter screen 21, and the other end of the return spring 52 is fixed to the inner wall of the cleaning groove 43. One end of the connecting rope 53 is fixed to the side wall of the cleaning claw 51 near the return spring 52, and the other end of the connecting rope 53 extends to the outside of the filter tank 1 and is slidably connected. The fixing plate 6 is a rectangular plate structure, and the fixing plate 6 is installed together on the side walls of the multiple connecting ropes 53.

[0034] When the staff needs to clean the filter 21, the staff only needs to slide the slider 41 downward to move the cleaning rod 42 downward, so that the multiple cleaning claws 51 move downward along with the cleaning rod 42, so that the plant fibers and other impurities attached to the side walls of the filter 21 are moved downward by the cleaning claws 51. Subsequently, when the cleaning claws 51 move to the lowest point, the staff only needs to pull the fixed plate 6 to make the multiple cleaning claws 51 move along with the fixed plate 6 at the same time, thereby gradually moving the multiple cleaning claws 51 completely into the cleaning groove 43. During this process, the plant fibers and other impurities hanging on the cleaning claws 51 gradually separate from the cleaning claws. Furthermore, the staff only needs to loosen the fixed plate 6 to reset the multiple cleaning claws 51, thereby reducing the difficulty of cleaning the filter 21 for the staff.

[0035] To improve the user experience of the staff, a third chute 7 is opened at the upper end of the inner wall of the first chute 33. When the staff does not need to use the cleaning claw 51, the staff only needs to slide the slider 41 upward and pull the cleaning rod 42 to connect the slider 41 with the third chute 7, thereby keeping the cleaning rod 42 stable, thereby improving the user experience of the staff.

[0036] In order to reduce the difficulty for the staff to move the fixed plate 6, a handle 8 is fixed on the side wall of the fixed plate 6.

[0037] The operating principle of a construction river channel desilting device in this embodiment is as follows: when a worker needs to clean the silt in the river channel, the worker needs to place the suction end of the mud pump into the river channel and start the mud pump, so that the silt can be moved out of the river channel under the action of the mud pump. At this time, the filter screen 21 blocks impurities such as plant fibers, thereby reducing the probability of impurities such as plant fibers entering the mud pump. After the filter screen 21 has been used for a period of time, the worker needs to clean the filter screen 21. At this time, the worker only needs to move the filter tank 1 out of the river channel and start the cleaning component 4, so that the cleaning component 4 can clean the filter screen 21, thereby reducing the difficulty of the worker in cleaning the filter screen 21.
