Abstract
Description
Technical Field
[0001] This application relates to the technical field of sludge dewatering equipment, specifically a sludge dewatering device for river dredging in water conservancy projects. Background Technology
[0002] With the continuous development of water conservancy projects in my country, river dredging has become an important part of river management and water quality protection. As solid waste generated during the dredging process, the treatment and disposal of silt has always been a difficult problem in water conservancy projects. At present, many river dredging projects have adopted silt dewatering treatment devices, which use hydraulic compaction technology to dewater the silt, thereby reducing its volume and increasing its bulk density, thus facilitating transportation and final disposal.
[0003] Most existing sludge dewatering treatment devices use conveyor belt systems to transport sludge. During the dewatering process, hydraulic compaction devices compact the sludge, removing most of the water to facilitate subsequent processing and transportation. However, during the conveyor belt transport process, the part of the sludge closest to the conveyor belt surface adheres deeply to the conveyor belt, making subsequent cleaning difficult. Because this sludge residue remains on the conveyor belt surface, it causes the accumulation of dirt on the conveyor belt surface, which is not only difficult to clean but also greatly shortens the service life of the conveyor belt.
[0004] Therefore, this application provides a device for treating silt and dewatering sludge in river dredging for water conservancy projects to solve the above-mentioned problems. Utility Model Content
[0005] This application provides a silt dewatering treatment device for river dredging in water conservancy projects, which aims to solve the problem mentioned in the background art where the part of the silt closest to the surface of the conveyor belt is deeply attached to the conveyor belt, making subsequent cleaning work difficult.
[0006] To achieve the above objectives, this application provides the following technical solution: a silt dewatering treatment device for river dredging in water conservancy projects, comprising a feeding hopper and a conveyor frame disposed at the lower end of the feeding hopper, wherein a conveyor belt for transporting materials is disposed on the conveyor frame, a discharging frame is disposed at the end of the conveyor frame away from the feeding hopper, a support plate is installed at the lower end of the conveyor frame, and a hydraulic dewatering machine for dewatering the silt on the conveyor belt is fixedly installed at the upper end of the support plate; The lower end of the support plate is provided with a mud removal mechanism for cleaning the conveyor belt. The mud removal mechanism includes a cleaning box located at the lower end of the support plate. A partition plate is fixedly installed inside the cleaning box. A scraper blade for removing mud from the conveyor belt is installed on the side of the partition plate near the unloading frame. A brush roller is rotatably connected to the side of the partition plate away from the scraper blade. A servo motor is installed on the outside of the cleaning box. The output end of the servo motor is fixedly connected to the central axis of the brush roller. The scraper blade is made of cemented carbide, with a cutting edge angle of 30° and a gap of 0.5mm between it and the conveyor belt. The upper end of the cleaning box is provided with a splash guard connected to the lower end of the support plate, and a limit roller is fixedly installed inside the splash guard.
[0007] Preferably, an assembly base is installed on the partition plate, and a liquid guide pipe is fixedly installed on the assembly base. Several high-pressure nozzles are installed at equal intervals on the liquid guide pipe. The high-pressure nozzles are arranged in a straight line to effectively cover the full width of the conveyor belt. High-pressure rinsing, in conjunction with a brush roller, can remove small adhesive particles.
[0008] Preferably, the outlet of the high-pressure nozzle is provided with an anti-clogging filter ring, and the high-pressure nozzle is vertically installed on the liquid guide pipe.
[0009] Preferably, the cleaning box has two sets of anti-splash arc plates distributed opposite each other, and the two sets of anti-splash arc plates are symmetrically distributed with the brush roller as the center.
[0010] Preferably, a plurality of mud-cleaning comb rods are equidistantly installed on the anti-splash arc plate. The mud-cleaning comb rods are used to remove residual mud from the brush after the brush on the surface of the brush roller comes into contact with the brush and through scraping contact.
[0011] Preferably, both the cleaning box and the partition plate are equipped with limiting rails, and a filter screen is movably inserted into the cleaning box, with the filter screen slidably connected to the limiting rail.
[0012] In this sludge dewatering treatment device, sludge falls from the hopper onto the conveyor belt of the conveyor frame. After being squeezed and dewatered by the hydraulic dewatering machine, it is discharged from the unloading frame. In the sludge removal mechanism, the servo motor drives the brush roller to rotate, which works with the scraper blade to remove the sludge remaining on the conveyor belt. The partition plate divides the cleaning box into a scraping area and a washing area to achieve multi-level cleaning, thereby ensuring that the conveyor belt remains clean after the work is completed and preventing the residual sludge on the surface from accelerating the reduction of the conveyor belt's service life.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0016] This embodiment provides a device for dewatering and treating silt from river dredging in water conservancy projects, such as... Figure 1-5 As shown, it includes a feeding hopper 1 and a conveyor frame 2 set at the lower end of the feeding hopper 1. The conveyor frame 2 is equipped with a conveyor belt for transporting materials. A discharging frame 6 is set at the end of the conveyor frame 2 away from the feeding hopper 1. A support plate 4 is installed at the lower end of the conveyor frame 2. A hydraulic dewatering machine 3 for dewatering sludge on the conveyor belt is fixedly installed at the upper end of the support plate 4. The lower end of the support plate 4 is provided with a mud removal mechanism 5 for cleaning the conveyor belt; The mud removal mechanism 5 includes a cleaning box 51 located at the lower end of the support plate 4. A partition plate 53 is fixedly installed inside the cleaning box 51. A scraper blade 54 for removing mud from the conveyor belt is installed on the side of the partition plate 53 near the unloading frame 6. A brush roller 56 is rotatably connected on the side of the partition plate 53 away from the scraper blade 54. A servo motor 58 is installed on the outside of the cleaning box 51. The output end of the servo motor 58 is fixedly connected to the central shaft of the brush roller 56. The upper end of the cleaning box 51 is provided with a splash cover 52 connected to the lower end of the support plate 4, and a limit roller 521 is fixedly installed inside the splash cover 52.
[0017] Specifically, the feeding hopper 1, the conveyor belt on the conveyor frame 2, and the hydraulic dewatering machine 3 for dewatering sludge in this solution are all publicly disclosed technologies in the existing field. The hydraulic dewatering machine 3 mainly uses hydraulic cylinders and gates to compact and dewater the sludge. The sludge falls from the feeding hopper 1 into the conveyor belt of the conveyor frame 2. After being squeezed and dewatered by the hydraulic dewatering machine 3, it is discharged from the unloading frame 6. In the sludge removal mechanism 5, the servo motor 58 drives the brush roller 56 to rotate, which works with the scraper blade 54 to remove the residual sludge on the conveyor belt. The partition plate 53 divides the cleaning box 51 into a scraping area and a brushing area to achieve multi-level cleaning. The entire sludge removal mechanism 5 is installed at the bottom of the conveyor belt circulation path of the conveyor frame 2. The sludge removal mechanism 5 can be installed at any position on the bottom base of the conveyor frame 2. The conveyor belt must be in a horizontal moving state. The bristles on the surface of the brush roller 56 are made of nylon, which is a high-hardness material and effectively removes the adhering sludge.
[0018] A mounting base 55 is installed on the partition plate 53. A liquid guide pipe 551 is fixedly installed on the mounting base 55. Several high-pressure nozzles 552 are installed at equal intervals on the liquid guide pipe 551. Anti-clogging filter rings are provided at the outlet of the high-pressure nozzles 552, and the high-pressure nozzles 552 are vertically installed on the liquid guide pipe 551.
[0019] More specifically, the liquid guide pipe 551 is connected to a high-pressure water source, and the high-pressure nozzle 552 sprays water vertically to rinse away the fine sludge remaining on the back of the conveyor belt, filter impurities in the water to prevent the nozzles from clogging, and the cleaning box 51 has a water inlet on the side for injecting water into the liquid guide pipe 551 and a water outlet on the other side for draining water. The high-pressure nozzles 552 are arranged in a straight line to effectively cover the full width of the conveyor belt. The high-pressure rinsing, together with the brush roller 56, can remove small adhesive particles, improve the cleanliness of the conveyor belt, and reduce subsequent secondary pollution from sludge.
[0020] Inside the cleaning box 51, there are two sets of anti-splash arc plates 57, which are symmetrically distributed with the brush roller 56 as the center. Several mud cleaning comb rods 571 are installed at equal intervals on the anti-splash arc plates 57.
[0021] It should be noted that the anti-splash arc plate 57 blocks the splashing of rinsing water, and the mud-cleaning comb rod 571 is used to comb away the residual mud on the brush after the brush on the surface of the brush roller 56 comes into contact with the brush and through scraping contact.
[0022] Limiting rails are installed on both the cleaning box 51 and the partition plate 53. A filter screen 59 is movably inserted into the cleaning box 51, and the filter screen 59 is slidably connected to the limiting rail.
[0023] It is worth mentioning that the cleaning box 51 is made of 304 stainless steel, and is rectangular in shape with an open top. The filter screen 59 is slidably installed on the limiting rail seat to filter the silt particles carried by the rinsing water. The filtrate can be recycled and reused, and the filter residue is cleaned regularly. The filter screen 59 is concave, and the concave part is used for residue accumulation. The filter screen 59 can be periodically pulled out from the cleaning box 51 to remove the residue remaining on the filter screen 59.
[0024] During use, sludge falls from the hopper 1 onto the conveyor belt of the conveyor frame 2. After being squeezed and dehydrated by the hydraulic dewatering machine 3, it is discharged from the unloading frame 6. In the sludge removal mechanism 5, the servo motor 58 drives the brush roller 56 to rotate, which works with the scraper blade 54 to remove the sludge remaining on the conveyor belt. The partition plate 53 divides the cleaning box 51 into a scraping area and a washing area to achieve multi-level cleaning, thereby ensuring that the conveyor belt can remain clean after the work is completed and preventing the residual sludge on the surface from accelerating the reduction of the service life of the conveyor belt.
[0025] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
