Description

Technical Field

[0001] This utility model relates to the field of quantitative sludge mixing technology, specifically to a quantitative mixing device for sludge mixing and conveying. Background Technology

[0002] With increasingly stringent environmental protection requirements and the continuous expansion of wastewater treatment scale, sludge treatment and disposal have become a key link in the field of environmental engineering. In the process of sludge treatment, it is often necessary to mix sludge from different sources and with different properties to meet the requirements of specific subsequent treatment processes, such as anaerobic digestion, aerobic fermentation, dewatering and drying, incineration, or resource utilization of sludge.

[0003] Traditional sludge mixing methods often rely on rudimentary equipment and crude operating procedures. In the material feeding stage, the lack of precise quantitative control makes it difficult to mix different types of sludge in accurate proportions, easily leading to unstable quality of the mixed sludge and failing to achieve the expected treatment effect. Furthermore, due to the inherent viscosity and complex composition of sludge, it is prone to adhering to the inner walls of pipes and clogging them during the conveying and feeding process. Traditional equipment typically requires shutdown for manual cleaning to address these issues, which not only consumes significant manpower, resources, and time but also severely impacts production continuity and efficiency. Simultaneously, during the mixing process, materials easily adhere to the inner walls of the mixing container, creating dead zones. These unmixed materials reduce the overall quality of the mixed sludge, affecting the normal operation of subsequent treatment processes. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a quantitative mixing device for sludge mixing and conveying, comprising: a mixing device, wherein a feeding device is symmetrically and fixedly connected to the inner wall of the top of the mixing device; the feeding device includes a feeding pipe, an inlet pipe is fixedly connected to the inner wall of the feeding pipe, symmetrical grooves are formed on the outer wall of the side of the feeding pipe, a rotating groove is formed on the outer wall of the top of the feeding pipe, a handle is slidably connected to the inner wall of the rotating groove, an adjusting threaded rod is threadedly connected to the inner wall of the handle, a scraper is rotatably connected to the outer wall of the bottom of the adjusting threaded rod, an opening and closing frame is fixedly connected to the outer wall of the feeding pipe, an opening and closing threaded rod is symmetrically and rotatably connected to the outer wall of the side of the opening and closing frame, an opening and closing helical gear is fixedly connected to the outer wall of the opening and closing threaded rod, a support plate is threadedly connected to the outer wall of the opening and closing threaded rod on the side away from the opening and closing helical gear, an opening and closing plate is fixedly connected to the outer wall of the support plate, a rotating rod is rotatably connected to the inner wall of the opening and closing frame, and an adjusting helical gear is fixedly connected to the outer wall of the rotating rod.

[0005] Preferably, the inside of the feed pipe is connected to the inside of the discharge pipe, the outer wall of the scraper is slidably connected to the inner wall of the discharge pipe, and the handle is rotated along the rotating groove. Since the inner wall of the handle is threadedly connected to an adjusting threaded rod, and the outer wall of the bottom of the adjusting threaded rod is rotatably connected to the scraper, the adjusting threaded rod is driven by the handle to move the scraper up and down along the inner wall of the discharge pipe.

[0006] Preferably, the outer wall of the opening and closing plate is slidably connected to the inner wall of the slide groove, and the outer wall of the adjusting helical gear meshes with the outer wall of the opening and closing helical gear. Rotating the rotating rod drives the adjusting helical gear to rotate. Since the adjusting helical gear meshes with the opening and closing helical gear, the opening and closing helical gear will rotate accordingly, thereby driving the opening and closing threaded rod fixedly connected to it to rotate along the opening and closing frame. When the opening and closing threaded rod rotates, the support plate threadedly connected to it will move along the axial direction of the opening and closing threaded rod. Because the support plate is restricted by the sliding connection relationship between the opening and closing plate and the slide groove, it can only move in a straight line, thereby driving the opening and closing plate to slide in the slide groove.

[0007] Preferably, the mixing device includes a mixing tank, a support frame is fixedly connected to the outer wall of the top of the mixing tank, a motor is fixedly connected to the inner wall of the top of the support frame, a rotating shaft is rotatably connected to the outer wall of the bottom of the motor, a stirring blade is fixedly connected to the outer wall of the rotating shaft, a scraper is fixedly connected to the outer wall of the stirring blade, and a support frame is fixedly connected to the outer wall of the mixing tank.

[0008] Preferably, the outer wall of the rotating shaft is rotatably connected to the inner wall of the top of the mixing tank, and the outer wall of the scraper is slidably connected to the inner wall of the mixing tank. The motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade fixed on its outer wall to rotate together during the rotation. When the stirring blade rotates with the rotating shaft, the scraper will continuously scrape the inner wall of the mixing tank.

[0009] Preferably, the outer wall of the feeding pipe is fixedly connected to the inner wall of the top of the mixing tank, and the inside of the feeding pipe is connected to the inside of the mixing tank, so that the material falls into the mixing tank through the feeding pipe.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a feeding device, uses a rotating rod to drive an adjusting helical gear and an opening and closing helical gear to engage with each other, so that the opening and closing threaded rod and the support plate are threaded together, allowing the opening and closing plate to slide within the groove. This precisely controls the opening and closing degree of the feeding channel, effectively avoiding excessive or insufficient material supply. The feeding device is equipped with an adjustable scraper. When encountering material adhesion or blockage, especially materials with certain viscosity and complex components such as sludge, the handle can be easily operated to make the adjusting threaded rod drive the scraper to slide up and down along the inner wall of the feeding pipe. This design can not only promptly clean the material adhering to the inner wall of the feeding pipe, but also, in the event of a blockage, the scraper can move downward to squeeze the material out of the feeding pipe, quickly restoring production operation and greatly improving the operating efficiency and stability of the equipment.

[0012] 2. This utility model incorporates a mixing device. The motor in the mixing device drives the rotating shaft to rotate, thereby causing the stirring blades to stir the materials falling into the mixing tank. At the same time, the scraper fixed on the stirring blades is slidably connected to the inner wall of the mixing tank, effectively preventing the materials from adhering to the tank wall and ensuring that all materials participate in the mixing process, further enhancing the mixing effect.

The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0023] Example:

[0024] Please see Figure 1 - Figure 8 This utility model provides a technical solution: a quantitative mixing device for sludge mixing and conveying, comprising: a mixing device 1, with a feeding device 2 symmetrically fixedly connected to the inner wall of the top of the mixing device 1; the feeding device 2 includes a feeding pipe 21, with an inlet pipe 22 fixedly connected to the inner wall of the feeding pipe 21, symmetrically formed grooves 23 on the outer wall of the side of the feeding pipe 21, and a rotating groove 24 formed on the outer wall of the top of the feeding pipe 21, with a handle 25 slidably connected to the inner wall of the rotating groove 24, and an adjusting threaded rod 26 threadedly connected to the inner wall of the handle 25. A scraper 27 is rotatably connected to the outer wall of the bottom. An opening and closing frame 28 is fixedly connected to the outer wall of the discharge pipe 21. An opening and closing threaded rod 281 is symmetrically rotatably connected to the outer wall of the side of the opening and closing frame 28. An opening and closing helical gear 282 is fixedly connected to the outer wall of the opening and closing threaded rod 281 on the side away from the opening and closing helical gear 282. A support plate 283 is threadedly connected to the outer wall of the support plate 283. An opening and closing plate 284 is fixedly connected to the outer wall of the support plate 283. A rotating rod 29 is rotatably connected to the inner wall of the opening and closing frame 28. An adjusting helical gear 291 is fixedly connected to the outer wall of the rotating rod 29.

[0025] The inside of the feed pipe 22 is connected to the inside of the discharge pipe 21. The outer wall of the scraper 27 is slidably connected to the inner wall of the discharge pipe 21. The handle 25 is rotated along the rotating groove 24. Since the inner wall of the handle 25 is threadedly connected to the adjusting thread rod 26, and the outer wall of the bottom of the adjusting thread rod 26 is rotatably connected to the scraper 27, the handle 25 causes the adjusting thread rod 26 to drive the scraper 27 to slide up and down along the inner wall of the discharge pipe 21.

[0026] The outer wall of the opening and closing plate 284 is slidably connected to the inner wall of the slide groove 23. The outer wall of the adjusting helical gear 291 meshes with the outer wall of the opening and closing helical gear 282. Rotating the rotating rod 29 drives the adjusting helical gear 291 to rotate. Since the adjusting helical gear 291 meshes with the opening and closing helical gear 282, the opening and closing helical gear 282 will rotate accordingly, thereby driving the opening and closing threaded rod 281 fixedly connected to it to rotate along the opening and closing frame 28. When the opening and closing threaded rod 281 rotates, the support plate 283 threadedly connected to it will move along the axial direction of the opening and closing threaded rod 281. Because the support plate 283 is restricted by the sliding connection relationship between the opening and closing plate 284 and the slide groove 23, it can only move in a straight line, thereby driving the opening and closing plate 284 to slide in the slide groove 23.

[0027] The mixing device 1 includes a mixing tank 11. A support frame 12 is fixedly connected to the outer wall of the top of the mixing tank 11. A motor 13 is fixedly connected to the inner wall of the top of the support frame 12. A rotating shaft 14 is rotatably connected to the outer wall of the bottom of the motor 13. A stirring blade 15 is fixedly connected to the outer wall of the rotating shaft 14. A scraper 16 is fixedly connected to the outer wall of the stirring blade 15. A support frame 17 is fixedly connected to the outer wall of the mixing tank 11.

[0028] The outer wall of the rotating shaft 14 is rotatably connected to the inner wall of the top of the mixing tank 11, and the outer wall of the scraper 16 is slidably connected to the inner wall of the mixing tank 11. The motor 13 drives the rotating shaft 14 to rotate. During the rotation, the rotating shaft 14 drives the stirring blade 15 fixed on its outer wall to rotate together. When the stirring blade 15 rotates with the rotating shaft 14, the scraper 16 will continuously scrape the inner wall of the mixing tank 11.

[0029] The outer wall of the feeding pipe 21 is fixedly connected to the inner wall of the top of the mixing tank 11, and the inside of the feeding pipe 21 is connected to the inside of the mixing tank 11. The material falls into the mixing tank 11 through the feeding pipe 21.

[0030] Working principle: First, the material enters the discharge pipe 21 through the feed pipe 22 in the discharge device 2. The feed pipe 22 is connected to the discharge pipe 21 to ensure that the material can flow smoothly into the discharge pipe 21. When it is necessary to adjust the discharge amount, rotate the rotating rod 29. The rotating rod 29 drives the adjusting helical gear 291 to rotate. Since the adjusting helical gear 291 meshes with the opening and closing helical gear 282, the opening and closing helical gear 282 will rotate accordingly, thereby driving the opening and closing threaded rod 281 fixedly connected to it to rotate along the opening and closing frame 28. The opening and closing threaded rod 281 rotates... When in motion, the support plate 283, which is threadedly connected to it, will move along the axial direction of the opening and closing threaded rod 281. Because the support plate 283 is restricted by the sliding connection between the opening and closing plate 284 and the slide groove 23, it can only move in a straight line, thereby driving the opening and closing plate 284 to slide in the slide groove 23. When the symmetrical opening and closing plate 284 moves to the middle until it closes, it can completely cut off the feeding channel and prevent the material from falling further. When the opening and closing plate 284 moves to both sides to open, the feeding situation of the material can be precisely controlled according to the degree of opening, so as to realize the function of quantitative feeding.

[0031] When encountering material adhesion or blockage, the rotating handle 25 can be rotated along the rotating trough 24. Since the inner wall of the rotating handle 25 is threadedly connected to the adjusting thread rod 26, and the outer wall of the bottom of the adjusting thread rod 26 is rotatably connected to the scraper 27, the rotating handle 25 causes the adjusting thread rod 26 to drive the scraper 27 to slide up and down along the inner wall of the discharge pipe 21, which can clean the material adhering to the inner wall of the discharge pipe 21. At the same time, in the case of blockage, the scraper 27 can also be moved downward to squeeze the material out of the discharge pipe 21.

[0032] In the mixing device 1, the motor 13 is fixed to the inner wall of the top of the support frame 12. After the motor 13 is started, the motor 13 drives the rotating shaft 14 to rotate. During the rotation of the rotating shaft 14, the stirring blade 15 fixed to its outer wall rotates together. The stirring blade 15 stirs and mixes the material falling into the mixing tank 11 from the feeding pipe 21. Through the rotation of the stirring blade 15, the material is fully turned over and collided in the mixing tank 11, so as to achieve uniform mixing between different materials. At the same time, the scraper 16 fixed on the stirring blade 15 has its outer wall slidably connected to the inner wall of the mixing tank 11. When the stirring blade 15 rotates with the rotating shaft 14, the scraper 16 will continuously scrape the inner wall of the mixing tank 11, which can prevent the material from adhering to the inner wall of the mixing tank 11 and affecting the mixing effect, ensuring that all materials can participate in the mixing process. The mixing tank 11 is fixedly supported by the support frame 17 to ensure the stability of the entire mixing device 1 during operation.

[0033] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
