Description

A sludge treatment system Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge treatment system. Background Technology

[0002] The sludge treatment system plays three main roles. First, it reduces volume, as kitchen waste sludge is bulky. Through the concentration and dewatering processes in the system, the volume of the sludge is reduced, making it easier for subsequent processing and transportation. Second, it renders the sludge harmless, using high temperatures and chemical disinfection to kill harmful organisms such as pathogens and parasite eggs in the sludge, ensuring that the treated sludge does not pose a threat to the environment or human health. Finally, it enables resource recovery. Considering that kitchen waste sludge contains rich organic nutrients, the system converts the sludge into organic fertilizer through fermentation and composting for use in agriculture and horticulture, or extracts bioenergy components such as biogas, achieving effective resource utilization.

[0003] A search revealed Chinese Patent Publication No. CN118545885B, which discloses a sludge treatment system. This system relates to the field of sludge treatment technology and aims to solve the problems of limited space at disposal sites, large sludge volume, and low equipment dewatering efficiency. The key technical points are: sludge is fed from a sludge tank into a sludge screening device for screening coarse and fine particles. After screening, the sludge sequentially enters a sludge thickening pipeline and a dewatering hydrocyclone for dewatering. Finally, it is discharged into a sludge-water separation device for water and soil separation. The water separated from the sludge in the sludge thickening pipeline, dewatering hydrocyclone, and sludge-water separation device is returned to the wastewater treatment system. The system returns to the mud tank. The invention uses a mud screening device to screen out coarse particles in the mud. The mud is dewatered in the mud thickening pipeline and dewatering hydrocyclone, and water and soil are separated in the mud-water separation device. The invention performs gradual dewatering and thickening during the mud transportation process, which reduces the processing time of mud in water and soil separation when processing large amounts of mud and improves separation efficiency. In contrast, existing sludge treatment systems start stirring and dewatering the sludge directly after it is poured into the equipment. However, there are some large-volume debris in these untreated sludge, which can cause equipment blockage. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a sludge treatment system, which aims to improve the problem in the prior art where large-volume waste in untreated sludge causes equipment blockage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sludge treatment system, comprising a frame, a motor fixedly connected to the upper middle part of the front side of the frame, a connecting rod fixedly connected to the output end of the motor, a drive sprocket fixedly connected to the rear end of the connecting rod, two rotating rods rotatably connected at equal intervals to the inner side of the frame, a driven sprocket fixedly connected to the front end of the left rotating rod, the drive sprocket being connected to the driven sprocket via a chain, a screen being provided on the outer side of both rotating rods, and a stirring mechanism installed at the left end of the front side of the frame, the stirring mechanism being used for stirring sludge with other chemical agents.

[0006] The above technical solution works as follows: the motor drives the connecting rod to rotate, and the drive sprocket fixed behind it will also rotate synchronously. At this time, the drive sprocket will drive the driven sprocket to rotate synchronously through the chain. As the drive sprocket and the driven sprocket rotate, the two rotating rods fixed behind them will also rotate together. When the two rotating rods rotate, the screen fixed outside them will also start to rotate. When the poured sludge falls onto the screen, larger garbage will be intercepted on the screen and then carried to another partition in the frame and fall down as the screen rotates.

[0007] As a further description of the above technical solution:

[0008] The stirring mechanism includes a power bevel gear, which is fixedly connected to the front end of the outer wall of the connecting rod. A transmission rod is rotatably connected to the left side of the upper middle front end of the frame. Transmission bevel gears are fixedly connected to both the left and right ends of the transmission rod. The transmission bevel gear on the right side meshes with the power bevel gear. A stirring tank is fixedly connected to the front left side of the frame. A stirring rod is rotatably connected to the middle of the stirring tank. A driven bevel gear is fixedly connected to the top of the stirring rod.

[0009] Through the above technical solution: when the sludge is screened by the screen, the power bevel gear fixed on the connecting rod will also be driven to rotate synchronously. When the power bevel gear rotates, it will drive the transmission bevel gear to rotate together through meshing. When the transmission bevel gear rotates, it will drive the driven bevel gear to rotate synchronously in conjunction with the transmission rod. As the driven bevel gear rotates, the stirring rod will start to rotate. The rotation of the stirring rod can stir the treated sludge in the mixing tank.

[0010] As a further description of the above technical solution:

[0011] Two support rods are fixedly connected at equal intervals to the top of the frame, and a solar panel is fixedly connected to the top of each of the two support rods.

[0012] The above technical solution allows the solar panel to be fixed to the frame by a support rod, enabling it to supply power to the motor during power outages.

[0013] As a further description of the above technical solution:

[0014] The top of the mixing tank is connected to a conveying pipe, and the top of the conveying pipe is connected to a funnel.

[0015] The above technical solution involves pouring chemical reagents into a mixing tank through a feed pipe, with a funnel facilitating the pouring of the reagents.

[0016] As a further description of the above technical solution:

[0017] The top rear side of the funnel is threaded with a hinge, and the upper front side of the hinge is threaded with a dust cover.

[0018] The above technical solution allows for the use of a dust cover secured by a hinge to prevent dust and foreign objects from entering the funnel.

[0019] As a further description of the above technical solution:

[0020] The bottom of the mixing tank is connected to a sewage conveying pipe, and a ball valve is fixedly connected to the front end of the sewage conveying pipe.

[0021] The above technical solution involves using a sewage conveying pipe to transport the mixed sludge, with a ball valve controlling its opening and closing.

[0022] As a further description of the above technical solution:

[0023] Multiple anti-slip sleeves are equidistantly installed on the front end of the outer wall of the ball valve, and Velcro is fixedly connected to the left and right sides of the multiple anti-slip sleeves.

[0024] The above technical solution enhances the anti-slip performance of the ball valve handle by using a Velcro-attached anti-slip sleeve.

[0025] As a further description of the above technical solution:

[0026] The rear end of the sewage conveying pipe is connected to a filter pipe, and the rear end of the filter pipe is connected to a centrifuge.

[0027] The above technical solution involves using filter tubes to further filter sludge, while centrifuges are responsible for sludge dewatering.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the motor drives the active sprocket, chain and driven sprocket to rotate through the connecting rod, thereby controlling the rotating rod to drive the screen to rotate, thus achieving the effect of screening large-volume garbage, which is convenient for centralized processing in the later stage.

[0030] 2. In this utility model, the motor drives the stirring rod to rotate through the transmission of the power bevel gear, the transmission bevel gear, the transmission rod and the driven bevel gear. The rotation of the stirring rod can stir the treated sludge in the mixing tank, so that it can better mix with the chemical agents added therein, thereby achieving the effect of rapid and uniform mixing of sludge and chemical agents.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Referring to Figure 2, an embodiment of this utility model is provided: a sludge treatment system, including a frame 1. A motor 3 is fixedly connected to the upper middle part of the front side of the frame 1. A connecting rod 4 is fixedly connected to the output end of the motor 3. A drive sprocket 5 is fixedly connected to the rear end of the connecting rod 4. The motor 3 drives the drive sprocket 5 to rotate through the connecting rod 4. Two rotating rods 8 are equidistantly rotatably connected to the inner side of the frame 1. A driven sprocket 6 is fixedly connected to the front end of the left rotating rod 8. The drive sprocket 5 is connected to the driven sprocket 6 through a chain 7. The drive sprocket 5 drives the driven sprocket 6 to rotate through the chain 7. A screen 9 is provided on the outer side of both rotating rods 8. The drive sprocket 5 and the driven sprocket 6 drive the screen 9 to rotate through the two rotating rods 8. A stirring mechanism 2 is installed on the left side of the front side of the frame 1. The stirring mechanism 2 is used to stir sludge with other chemical agents. Two support rods 10 are fixedly connected to the top of the frame 1 at equal intervals. A solar panel 11 is fixedly connected to the top of both support rods 10. The solar panel 11 can provide energy to the motor 3 when there is a power outage.

[0040] Specifically, the motor 3 drives the connecting rod 4 to rotate. When the connecting rod 4 rotates, the drive sprocket 5 fixed behind it will also rotate synchronously. At this time, the drive sprocket 5 will drive the driven sprocket 6 to rotate synchronously through the chain 7. As the drive sprocket 5 and the driven sprocket 6 rotate, the two rotating rods 8 fixed behind them will also rotate. When the two rotating rods 8 rotate, the screen 9 fixed outside them will also start to rotate. When the poured sludge falls onto the screen 9, the larger garbage will be intercepted on the screen 9. Then, as the screen 9 rotates, it will be carried to another partition in the frame 1 and fall down, thus achieving the effect of screening larger garbage. The solar panel 11 fixed to the top of the frame 1 by the support rod 10 can provide energy for the motor 3 when there is a power outage.

[0041] Referring to Figures 3 and 4, the stirring mechanism 2 includes a power bevel gear 201, which is fixedly connected to the front end of the outer wall of the connecting rod 4. A transmission rod 202 is rotatably connected to the left side of the upper middle front end of the frame 1. Transmission bevel gears 203 are fixedly connected to both the left and right ends of the transmission rod 202. The power bevel gear 201 drives the transmission bevel gears 203 and the transmission rod 202 to rotate. The right transmission bevel gear 203 meshes with the power bevel gear 201. A stirring tank 204 is fixedly connected to the front left side of the frame 1. A stirring rod is rotatably connected to the middle of the stirring tank 204. A stirring rod 205 is fixedly connected to a driven bevel gear 206 at its top. The driven bevel gear 206 drives the stirring rod 205 to rotate and stir the sludge in the mixing tank 204. A conveying pipe 12 is connected to the top of the mixing tank 204, and a funnel 13 is connected to the top of the conveying pipe 12. Chemical agents are poured into the mixing tank 204 through the funnel 13 and the conveying pipe 12. A hinge 14 is threadedly connected to the top rear side of the funnel 13, and a dust cover 15 is threadedly connected to the upper front side of the hinge 14. The dust cover 15 can prevent dust from falling into the funnel 13.

[0042] Specifically, when the sludge is screened by the screen 9, the power bevel gear 201 fixed on the connecting rod 4 is also driven to rotate synchronously. When the power bevel gear 201 rotates, it drives the transmission bevel gear 203 to rotate together through meshing. When the transmission bevel gear 203 rotates, it cooperates with the transmission rod 202 to drive the driven bevel gear 206 to rotate synchronously. As the driven bevel gear 206 rotates, the stirring rod 205 starts to rotate. The rotation of the stirring rod 205 can stir the treated sludge in the mixing tank 204, so that it can better mix with the chemical agents added therein, thereby achieving the effect of rapid and uniform mixing of sludge and chemical agents. Chemical agents are poured into the mixing tank 204 through the conveying pipe 12. The funnel 13 can more conveniently pour the chemical agents into the conveying pipe 12. The dust cover 15 fixed on the funnel 13 by the hinge 14 can prevent dust and foreign objects from falling into the funnel 13.

[0043] Referring to Figures 1 and 5, the bottom of the mixing tank 204 is connected to a sewage conveying pipe 16. A ball valve 17 is fixedly connected to the front end of the sewage conveying pipe 16. The ball valve 17 controls the opening and closing of the sewage conveying pipe 16. Multiple anti-slip sleeves 18 are equidistantly installed on the front end of the outer wall of the ball valve 17. Velcro straps 19 are fixedly connected to the left and right sides of the multiple anti-slip sleeves 18. The anti-slip sleeves 18 improve the anti-slip properties of the ball valve 17. The rear end of the sewage conveying pipe 16 is connected to a filter pipe 20. The rear end of the filter pipe 20 is connected to a centrifuge 21. The filter pipe 20 and the centrifuge 21 filter and dewater the sludge.

[0044] Specifically, the sludge after mixing is continued to be transported through the sewage pipe 16, while the ball valve 17 controls the opening and closing of the sewage pipe 16. The anti-slip sleeve 18, which is fixed to the handle of the ball valve 17 by Velcro 19, can improve its anti-slip properties. The filter pipe 20 is used to further filter the sludge, while the centrifuge 21 is used for the dewatering of the sludge.

[0045] Working principle: When sludge is poured into the sludge treatment equipment, motor 3 is started simultaneously. The power provided by motor 3 drives the connecting rod 4 to rotate. When the connecting rod 4 rotates, the drive sprocket 5 fixed behind it will also rotate synchronously. At this time, the drive sprocket 5 will drive the driven sprocket 6 to rotate synchronously through chain 7. As the drive sprocket 5 and the driven sprocket 6 rotate, the two rotating rods 8 fixed behind them will also rotate. When the two rotating rods 8 rotate, the screen 9 fixed outside them will also start to rotate. When the poured sludge falls onto the screen 9, larger waste will be intercepted on the screen 9. Then, as the screen 9 rotates, it will be carried to another partition in the frame 1 and fall down. This achieves the effect of screening larger waste, which is convenient for centralized processing later.

[0046] When the sludge is screened by the screen 9, the power bevel gear 201 fixed on the connecting rod 4 is also driven to rotate synchronously. When the power bevel gear 201 rotates, it drives the transmission bevel gear 203 to rotate together through meshing. When the transmission bevel gear 203 rotates, it drives the driven bevel gear 206 to rotate synchronously in conjunction with the transmission rod 202. As the driven bevel gear 206 rotates, the stirring rod 205 starts to rotate. The rotation of the stirring rod 205 can stir the treated sludge in the mixing tank 204, so that it can better mix with the chemical agents added therein, thereby achieving the effect of rapid and uniform mixing of sludge and chemical agents.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
