Description

Technical Field

[0001] This utility model relates to the field of sludge thickening tank technology, specifically to an integrated device for efficient sludge thickening and pretreatment. Background Technology

[0002] In existing technologies, large amounts of mud are generated during the construction of bridges, real estate projects, oil development projects, and river management projects, involving processes such as pile driving, drilling, or dredging. The mud is typically treated by installing on-site thickening equipment for concentration and dewatering. However, the installation process for this equipment is lengthy and it is difficult to move after installation. Therefore, it must be dismantled and transported on-site after project completion. This method results in the thickening equipment not being reusable, and the dismantling and assembly process is not only time-consuming and labor-intensive but also wastes equipment resources.

[0003] Chinese patent CN215275912U discloses a vehicle-mounted integrated high-density mud thickening tank device, which includes a tractor and a box mounted on the tractor frame. The box contains a mixing and coagulation chamber, a mud thickening tank, a flocculant dosing device, and a coagulant dosing device. The mixing and coagulation chamber is connected to a feed pipe for injecting mud. The mixing and coagulation chamber is equipped with a stirring device for stirring the mud injected through the feed pipe, the flocculant dosing device, and the coagulant dosing device. The mixing and coagulation chamber and the mud thickening tank are interconnected through a water distribution wall. The mud discharged from the mixing and coagulation chamber enters the mud thickening tank for thickening treatment after passing through the water distribution wall.

[0004] However, the agitator used in the coagulation chamber of the aforementioned patent merely drives the impeller to rotate via a motor, and several blades evenly distributed on the outer circumference of the impeller rotate accordingly. When the impeller rotates, the blades agitate the raw water, allowing the coagulant in the raw water to quickly mix with the raw water. In traditional agitators, the impeller is located in the middle of the coagulation zone. As the impeller drives the blades to rotate, the water flow in the middle of the coagulation zone flows with the blades and forms a vortex. The vortex in the middle of the coagulation zone then drives the water flow in the upper and lower parts of the coagulation zone, allowing the water to mix with the coagulant during the flow. However, the agitation amplitude that can be formed by the water flow in the middle of the coagulation zone driving the water flow in the upper and lower parts is extremely limited. The degree of mixing between the water flow in the upper and lower parts of the coagulation zone and the coagulant is much smaller than that in the middle of the coagulation zone. Only through long-term agitation can the water flow in the upper and lower parts of the coagulation zone be fully mixed with the coagulant, resulting in a decrease in overall sedimentation efficiency and affecting water treatment efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an integrated device for efficient sludge thickening and pretreatment, in order to solve the problem that only long-term stirring can fully integrate the water flow and coagulant in the upper and lower parts of the coagulation zone, resulting in a decrease in overall sedimentation efficiency and affecting water treatment efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated device for efficient sludge thickening and pretreatment, comprising: a tank body, a stirring and coagulation chamber provided on one side of the tank body, and a sludge thickening tank provided on the other side; a fixing plate is provided at both the front and rear ends of one side of the tank body, the fixing plate is L-shaped, one end of the fixing plate is fixed to the outer wall of the tank body, and the other end is located above the stirring and coagulation chamber.

[0007] A fixed shaft is fixedly installed at the lower end of one of the fixed plates. The outer end of the fixed shaft is rotatably connected to a second pulley and a large gear fixedly installed from top to bottom. Several small gears are evenly rotatably connected to the outer circumference of the lower end of the second pulley. The outer wall of each small gear meshes with the outer wall of the large gear. A stirring rod is fixedly installed at the lower end of each small gear. Several stirring blades are evenly fixedly installed at the outer end of the stirring rod.

[0008] Furthermore, a fixing groove is fixedly installed on both the front and rear ends of one side of the pool body, and one end of the fixing plate is inserted into the fixing groove and fixed with bolts.

[0009] Furthermore, a motor is fixedly installed on the upper end of another fixed plate. The output end of the motor rotates through the fixed plate and is fixedly installed with a pulley. A belt connects the pulley and the pulley.

[0010] Furthermore, a bearing is fixedly installed in the middle of the pulley, and the inner wall of the bearing is fixedly sleeved on the outer end of the fixed shaft.

[0011] Furthermore, a fixing sleeve is fixedly installed in the middle of the large gear, and the inner wall of the fixing sleeve is fixedly sleeved to the outer end of the fixing shaft.

[0012] Furthermore, the upper end of each pinion is rotatably connected to a round shaft via a bearing, and the upper end of the round shaft is fixedly installed at the lower end of the pulley.

[0013] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0014] This invention injects sludge into the mixing and coagulation chamber through a feed pipe, while simultaneously injecting flocculant and coagulant dosing devices. When the motor is started, it drives pulley one to rotate, which in turn drives pulley two to rotate via a belt. As pulley two rotates, it drives the stirring rod and stirring blades to rotate simultaneously with pulley two, thus quickly and evenly mixing the sludge, flocculant, and coagulant in the mixing and coagulation chamber and improving the sludge treatment efficiency.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] This utility model provides, for example Figures 1-5 As shown, an integrated device for efficient sludge thickening and pretreatment includes: a tank body 1, which is fixedly installed in a box on a tractor frame. A mixing and coagulation chamber 2 is provided on one side of the tank body 1, and a sludge thickening tank 3 is provided on the other side. Fixed plates 5 are provided at both the front and rear ends of one side of the tank body 1. The fixed plates 5 are L-shaped, with one end fixed to the outer wall of the tank body 1 and the other end located above the mixing and coagulation chamber 2. A fixed shaft 8 is fixedly installed at the lower end of one of the fixed plates 5. A pulley 9 and a large gear 12 are rotatably connected from top to bottom to the outer end of the fixed shaft 8. A bearing 10 is fixedly installed in the middle of the pulley 9. The inner wall of the bearing 10 is fixedly sleeved on the outer end of the fixed shaft 8. The outer wall of the bearing 10 and the side wall of the pulley 9 are fixedly connected. The pulley 9 rotates on the outer wall of the fixed shaft 8 through the bearing 10. A fixed sleeve 13 is fixedly installed in the middle of the large gear 12. The inner wall of the fixed sleeve 13 is fixedly sleeved on the outer end of the fixed shaft 8.

[0023] Several small gears 16 are evenly rotatably connected to the lower outer circumference of the pulley 2 9. The upper end of each small gear 16 is rotatably connected to a round shaft 14 through a bearing 2 15. The outer wall of the bearing 2 15 is fixed to the upper end of the small gear 16. The lower end of the round shaft 14 is inserted into and fixed to the inner end of the bearing 2 15. The upper end of the round shaft 14 is fixedly installed at the lower end of the pulley 2 9. The small gears 16 can rotate with the pulley 2 9, or they can rotate on their own at the lower end of the pulley 2 9 through the bearing 2 15.

[0024] The outer wall of each small gear 16 meshes with the outer wall of the large gear 12. A stirring rod 17 is fixedly installed at the lower end of each small gear 16. Several stirring blades 18 are evenly fixedly installed at the outer end of the stirring rod 17. When the pulley 2 9 rotates, it drives the small gear 16, stirring rod 17, and stirring blades 18 to rotate. When the small gear 16 rotates, it travels on the large gear 12, allowing the small gear 16 to drive the stirring rod 17 and stirring blades 18 to rotate. This allows the stirring rod 17 and stirring blades 18 to rotate while following the rotation of the pulley 2 9, quickly and evenly mixing the sludge, flocculant, and coagulant in the mixing and coagulation chamber 2. Then, it enters the sludge thickening tank 3 through the water distribution wall for thickening treatment, improving the sludge treatment efficiency.

[0025] like Figure 2 As shown, in some embodiments, a fixing groove 4 is fixedly installed on both the front and rear ends of one side of the pool body 1. One end of the fixing plate 5 is inserted into the fixing groove 4 and fixed with bolts. More specifically, one end of the fixing plate 5 is inserted into the fixing groove 4 and fixed with bolts. One end of the bolt passes through the fixing groove 4 and the side wall of the fixing plate 5 and is threaded to the outer wall of the pool body 1. When it is necessary to repair or replace the parts on the fixing plate 5, the bolts on the fixing groove 4 can be unscrewed, and the parts connected to the upper end of the fixing plate 5 can be removed, which facilitates quick disassembly and repair.

[0026] like Figure 3 As shown, in some embodiments, a motor 6 is fixedly installed on the upper end of another fixed plate 5. The output end of the motor 6 rotates through the fixed plate 5 and is fixedly installed with a pulley 7. When the motor 6 starts, it can drive the pulley 7 to rotate. A belt 11 is connected between the pulley 7 and the second pulley 9. More specifically, when the motor 6 starts, the motor 6 drives the pulley 7 to rotate, and the pulley 7 drives the second pulley 9 to rotate through the belt 11, thereby driving the stirring rod 17 and the stirring blade 18 to rotate.

[0027] Working principle:

[0028] Step 1: During construction, while injecting mud into the mixing and coagulation chamber 2 through the feed pipe, liquid chemicals are injected through the flocculant dosing equipment and the coagulant dosing equipment respectively;

[0029] Step 2: Then, when the motor 6 is started, it drives the pulley 7 to rotate. The pulley 7 drives the pulley 9 to rotate through the belt 11. When the pulley 9 rotates, it drives the stirring rod 17 and the stirring blade 18 to rotate while following the pulley 9, and quickly mixes the sludge, flocculant and coagulant in the mixing and coagulation chamber 2 evenly. Then, it enters the sludge thickening tank 3 through the water distribution wall for thickening treatment.
