Description

Technical Field

[0001] This application relates to the field of sludge treatment technology, specifically a sludge scraper with a liftable baffle. Background Technology

[0002] Water is the cornerstone of life, and sludge dewatering is particularly crucial at the end of the tap water and sewage treatment process. Among them, the horizontal flow sedimentation tank is an important component of the sludge dewatering system. With its rectangular design, it makes efficient use of space and relies on gravity to naturally settle suspended solids and impurities in sewage to achieve water purification. This facility is easy to operate and is widely applicable to various fields such as urban sewage, industrial wastewater and rainwater resource utilization. It is a key technology for water quality improvement and environmental protection.

[0003] However, most water supply plants currently use traveling siphon sludge removal trucks for their horizontal sedimentation tanks. Their operation is largely based on manual experience and has limited precision. This situation not only easily leads to problems such as substandard effluent quality and increased water consumption, but also results in low sludge removal efficiency and low solids content in the sludge, which in turn increases the burden on subsequent treatment and raises the overall operating cost. Therefore, optimizing the structure of the sludge removal truck and improving its automation and intelligence levels are of great significance for achieving the goals of high-efficiency water conservation, energy saving, and emission reduction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a sludge scraper with a liftable baffle. This scraper effectively assists in sludge aggregation, increases sludge solids content, maximizes sludge discharge efficiency, and avoids bringing sludge back to the starting point, thereby further optimizing the sludge discharge process and improving overall operational efficiency. This solves the problems of existing technologies, which rely heavily on manual experience for operation and have limited precision. These limitations not only easily lead to substandard effluent quality and increased water consumption, but also result in low sludge discharge efficiency and low sludge solids content.

[0005] To achieve the above objectives, this application provides the following technical solution: a sludge scraper with liftable baffles, comprising a sludge scraper truss, a frame arranged at equal intervals, and a baffle mechanism. The baffle mechanism includes cylinders arranged at equal intervals. The outer surface of each cylinder is fixedly connected to the outer surface of the sludge scraper truss. A pull rod is fixedly installed at the output end of each cylinder. A bracket is fixedly connected to the bottom end of each pull rod. Two liftable baffles are fixedly connected to the bottom surface of each bracket. Three rubber scrapers are fixedly installed on the outer surface of each liftable baffle. A sleeve is slidably connected to the outer surface of each pull rod. The outer surface of each sleeve is fixedly connected to the outer surface of the corresponding frame.

[0006] The above solution effectively assists in sludge aggregation during the vehicle's forward movement, increases sludge solids content, and maximizes sludge discharge efficiency. Furthermore, it prevents sludge from being carried back to the starting point during the return trip, further optimizing the sludge discharge process and improving overall operational efficiency. During the vehicle's movement, the liftable baffle in the baffle mechanism is lowered. The liftable baffle, along with the rubber scraper, effectively assists in sludge aggregation during forward movement, increasing sludge solids content and maximizing discharge efficiency. Upon return, a cylinder raises a lever, which in turn raises the support frame. The connection between the support frame and the liftable baffle, along with the rubber scraper, allows the liftable baffle and rubber scraper to rise, cleverly preventing sludge from being carried back to the starting point. This further optimizes the sludge discharge process and improves overall operational efficiency.

[0007] Furthermore, the upper surface of each frame is fixedly connected to the bottom surface of the sludge scraper truss, and a concentration meter is fixedly installed at the bottom of each frame.

[0008] The above scheme connects the upper surface of the frame to the bottom surface of the sludge scraper truss, making it fixed, thus installing the frame. The frame can move with the sludge scraper truss. The concentration meter is installed at the bottom of the frame. The concentration meter is a sludge concentration meter, which can monitor the sludge concentration. When the concentration meter detects that the sedimentation tank has reached the discharge standard, it sends a signal back to the control device.

[0009] Furthermore, a sludge suction pump is fixedly installed at the bottom of each frame, and a sludge suction pipe is fixedly connected to the input end of each sludge suction pump.

[0010] The above solution involves installing the sludge pump at the bottom of the frame, making it fixed, and installing the sludge suction pipe at the corresponding input end of the sludge suction pump. The sludge suction pipe adopts a horizontally distributed sludge suction branch pipe, and multiple sludge suction ports are arranged on the sludge suction branch pipe to spread the adsorption area, so as to avoid the sludge outside the sludge suction port being unable to be sucked in, thereby achieving a highly efficient sludge discharge effect, avoiding water waste, reducing economic losses, and saving costs.

[0011] Furthermore, a sedimentation tank is provided on the outside of the sludge scraper truss.

[0012] With the above method, the sedimentation tank is set outside the sludge scraper truss. Sludge and other impurities will settle at the bottom of the sedimentation tank. At this time, a sludge scraper is needed to remove the sludge and other impurities.

[0013] Furthermore, a siphon pipe is provided above the sludge scraper truss, and the output end of each sludge suction pump is fixedly connected to the siphon pipe through a pipe.

[0014] With the above scheme, the siphon pipe is set above the sludge scraper truss, and multiple connecting pipes are branched off from the surface of the siphon pipe. These pipes are connected to the output end of the corresponding sludge suction pump, which can then discharge the sucked-up sludge through the pipes and the siphon pipe.

[0015] Furthermore, the output end of the siphon extends to a drainage trough outside the sedimentation tank, and a siphon breaking mechanism is fixedly installed on the outer surface of the siphon.

[0016] The above scheme extends the output end of the siphon pipe to the drainage trough outside the sedimentation tank, which facilitates the discharge of sludge. The siphon breaking mechanism is installed on the outer surface of the siphon pipe to realize the installation of the siphon breaking mechanism. The siphon effect can be stopped by controlling the solenoid valve.

[0017] Furthermore, the concentration meter is installed next to the sludge suction pump at the bottom of the frame to collect sludge concentration data from the bottom of the sedimentation tank and feed it back to the central control unit.

[0018] With the above scheme, the concentration meter is installed next to the sludge pump at the bottom of the frame. The concentration meter can monitor the sludge concentration. When the sedimentation tank reaches the discharge standard, the signal is fed back to the control device, which then controls the baffle mechanism and the siphon sludge discharge device to perform sludge discharge.

[0019] Furthermore, the baffle mechanism is located at the rear end of the sludge scraper in the forward direction.

[0020] The above scheme places the baffle mechanism at the rear end of the sludge scraper in the forward direction of the sludge scraper, in order to assist in sludge accumulation and prevent sludge from being carried back to the starting point.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This type of sludge scraper with a liftable baffle, through the setting of cylinders, liftable baffles, rubber scrapers, and other components, allows the sludge to collect effectively during the forward movement of the machine, increasing the solids content of the sludge and maximizing sludge discharge efficiency. When the sludge scraper returns after completing its operation, the cylinder drives the pull rod to rise, which in turn causes the support frame, liftable baffle, and rubber scraper to rise, cleverly preventing the sludge from being brought back to the starting point. This further optimizes the sludge discharge process and improves overall operating efficiency. A concentration meter is installed at the bottom of the frame to monitor the sludge concentration. When the concentration meter detects that the sedimentation tank has reached the discharge standard, it sends a signal to the control device, which then controls the baffle mechanism and siphon sludge discharge device to perform sludge discharge. This eliminates the influence of manual experience settings on the system's sludge discharge effect. By scientifically setting the concentration parameters, precise control of the sludge discharge process is achieved. Attached Figure Description

[0024] 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.

[0025] Please see Figure 2 , Figure 3 and Figure 5 This embodiment of a sludge scraper with liftable baffles includes a sludge scraper truss 10, a frame 20 arranged at equal intervals, and a baffle mechanism 50. The baffle mechanism 50 includes cylinders 51 arranged at equal intervals. The outer surface of each cylinder 51 is fixedly connected to the outer surface of the sludge scraper truss 10. A pull rod 54 is fixedly installed at the output end of each cylinder 51. A bracket 53 is fixedly connected to the bottom end of each pull rod 54. Two liftable baffles 52 are fixedly connected to the bottom surface of each bracket 53. Three rubber scrapers 56 are fixedly installed on the outer surface of each liftable baffle 52. A sleeve 55 is slidably connected to the outer surface of each pull rod 54. The outer surface of each sleeve 55 is fixedly connected to the outer surface of the corresponding frame 20.

[0026] Please see Figure 1 , Figure 2 and Figure 4The upper surface of each frame 20 is fixedly connected to the bottom surface of the sludge scraper truss 10. A concentration meter 40 is fixedly installed at the bottom of each frame 20. The upper surface of the frame 20 is connected to the bottom surface of the sludge scraper truss 10 to fix it, thus realizing the installation of the frame 20. The frame 20 can move with the sludge scraper truss 10. The concentration meter 40 is installed at the bottom of the frame 20. The concentration meter 40 is a sludge concentration meter, which can monitor the sludge concentration. When the concentration meter 40 detects that the sedimentation tank 80 has reached the discharge standard, it feeds back the signal to the control device.

[0027] Please see Figure 2 , Figure 3 and Figure 4 Each frame 20 is fixedly equipped with a sludge suction pump 30 at its bottom end. The input end of each sludge suction pump 30 is fixedly connected to a sludge suction pipe 31. The sludge suction pump 30 is fixedly installed at the bottom end of the frame 20. The sludge suction pipe 31 is installed at the input end of the corresponding sludge suction pump 30. The sludge suction pipe 31 adopts horizontally distributed sludge suction branches, and multiple sludge suction ports are arranged on the sludge suction branches to spread the adsorption area and avoid the sludge outside the sludge suction port from being unable to be sucked in, thereby achieving a high-efficiency sludge discharge effect, avoiding water waste, reducing economic losses, and saving costs.

[0028] Please see Figure 2 The sludge scraper truss 10 is equipped with a sedimentation tank 80. The sedimentation tank 80 is located outside the sludge scraper truss 10. Sludge and other impurities will settle at the bottom of the sedimentation tank 80. At this time, a sludge scraper and suction machine is needed to remove the sludge and other impurities.

[0029] Please see Figure 2 A siphon pipe 60 is provided above the sludge scraper truss 10. The output end of each sludge suction pump 30 is fixedly connected to the siphon pipe 60 through a pipe. The siphon pipe 60 is set above the sludge scraper truss 10, and multiple connecting pipes are branched off from the surface of the siphon pipe 60. These pipes are connected to the output end of the corresponding sludge suction pump 30, and the sludge suction pump 30 can discharge the sucked-up sludge through the pipe and the siphon pipe 60.

[0030] Please see Figure 2 The output end of the siphon pipe 60 extends to the drainage trough outside the sedimentation tank 80. A siphon breaking mechanism 70 is fixedly installed on the outer surface of the siphon pipe 60. Extending the output end of the siphon pipe 60 to the drainage trough outside the sedimentation tank 80 facilitates the discharge of sludge. The siphon breaking mechanism 70 is installed on the outer surface of the siphon pipe 60. The siphon breaking mechanism 70 can be installed and stopped by a solenoid valve.

[0031] Please see Figure 3The concentration meter 40 is installed next to the sludge pump 30 at the bottom of the frame 20 to collect sludge concentration data at the bottom of the sedimentation tank 80 and feed it back to the central control. The concentration meter 40 can monitor the sludge concentration. When the sedimentation tank 80 is detected to have reached the discharge standard, the signal is fed back to the control device, which then controls the baffle mechanism 50 and the siphon sludge discharge device to perform sludge discharge.

[0032] Please see Figure 2 , Figure 3 and Figure 5 The baffle mechanism 50 is located at the rear end of the sludge scraper in the forward direction. Setting the baffle mechanism 50 at the rear end of the sludge scraper in the forward direction is to assist in sludge aggregation and prevent sludge from being carried back to the starting point.

[0033] This embodiment of a sludge scraper with a liftable baffle, through the setting of components such as cylinder 51, liftable baffle 52, and rubber scraper 56, allows the liftable baffle 52 to descend during the forward movement of the tractor, effectively assisting in sludge aggregation, increasing the solids content of the sludge, and ensuring maximum sludge discharge efficiency. When the tractor completes its return journey, cylinder 51 drives the pull rod 54 to rise, which in turn causes the support 53, liftable baffle 52, and rubber scraper 56 to rise, cleverly avoiding bringing the sludge back to the starting point, thereby further optimizing the sludge discharge process and improving overall operating efficiency. A concentration meter 40 is set at the bottom of the frame 20 to monitor the sludge concentration. When the concentration meter 40 detects that the sedimentation tank 80 has reached the discharge standard, it feeds back the signal to the control device, which then controls the baffle mechanism 50 and the siphon sludge discharge device to perform sludge discharge. This eliminates the influence of manual experience settings on the system's sludge discharge effect, and through scientifically setting the concentration parameters, it achieves refined control of the sludge discharge process.

[0034] It should be noted that the rubber scraper 56 is installed on the liftable baffle 52 by a pressure plate, and multiple bolt groups are used to fix the liftable baffle 52 and the rubber scraper 56. The rubber scraper 56 is located between the water collection troughs at the bottom of the sedimentation tank 80, and the length of the rubber scraper 56 is slightly smaller than the gap in the middle of the water collection trough. The sludge suction pipe 31 is located inside the rubber scraper 56, and the adjacent rubber scrapers 56 completely cover the corresponding area of ​​the water collection trough inside the sedimentation tank 80.

[0035] The working principle of the above embodiments is as follows: When sludge removal is required from sedimentation tank 80, the liftable baffle 52 and rubber scraper 56 are lowered. This allows the sludge to be extracted and discharged via the sludge pump 30, suction pipe 31, and siphon pipe 60 during the device's forward movement. The lowering of the liftable baffle 52 effectively assists in sludge aggregation, increases the sludge solids content, and maximizes sludge removal efficiency. When the scraper returns after completing its operation, cylinder 51 drives the pull rod 54 upward, which in turn drives the bracket 53, liftable baffle 52, and rubber scraper. The 56-liter height cleverly avoids bringing the sludge back to the starting point, thereby further optimizing the sludge discharge process and improving overall operating efficiency. A concentration meter 40 is installed at the bottom of the frame 20 to monitor the sludge concentration. When the concentration meter 40 detects that the sedimentation tank 80 has reached the discharge standard, it sends a signal to the control device, which then controls the baffle mechanism 50 and the siphon sludge discharge device to perform sludge discharge. This eliminates the influence of manual experience settings on the system's sludge discharge effect. By scientifically setting the concentration parameters, the sludge discharge process can be precisely controlled.
