Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for cement production, specifically a wastewater recycling mechanism for washing medium and coarse sand used in cement production. Background Technology

[0002] In cement production, medium and coarse sand is a key aggregate, and its mud content and impurity content directly affect the strength and stability of cement products. Therefore, it is necessary to remove mud, dust, and soluble impurities adhering to the surface of the sand and gravel through a washing process. However, traditional medium and coarse sand washing processes generally suffer from the dual problems of water waste and environmental pollution: the washing process consumes a large amount of fresh water resources, and the wastewater produced contains high concentrations of suspended solids, mud and sand particles, and small amounts of soluble salts. Direct discharge of this wastewater will cause water siltation and soil pollution, which does not meet environmental protection policy requirements. At the same time, the fine sand particles contained in the unrecycled wastewater also cause resource loss.

[0003] With increasingly stringent environmental regulations and a worsening water shortage, the recycling of wastewater from medium and coarse sand washing has become an inevitable trend in the industry. Existing wastewater recycling equipment mostly uses single filtration or sedimentation methods, which have significant limitations: some equipment only performs preliminary filtration of suspended particles through filters, resulting in high suspended solids content in the treated water. This can easily lead to secondary pollution of sand and gravel when recycled for washing, and the filters are prone to clogging and require frequent maintenance. Sedimentation-based recycling devices suffer from low separation efficiency and large footprint, making them unsuitable for the continuous operation requirements of cement production lines. Furthermore, existing equipment primarily focuses on the separation and recycling of concrete waste sand and gravel, with few specialized wastewater recycling solutions for the washing characteristics of medium and coarse sand used in cement production (such as high particle size requirements and high washing intensity). This results in low wastewater recycling rates and insufficient equipment adaptability, failing to fully meet the high-efficiency, environmentally friendly, and energy-saving requirements of cement production. Therefore, there is an urgent need to develop a wastewater recycling mechanism for medium and coarse sand washing that offers good separation performance, high recycling efficiency, and strong adaptability.

[0004] An investigation revealed that a Chinese utility model patent discloses a spiral sand washing and cleaning machine (publication number: CN222789946U), which includes a washing shell, spiral blades, a water storage tank, and a discharge shell. Four sets of connecting pipes are connected through the outer side of the water supply pipe. Multiple sets of water spray nozzles are installed through the bottom of the confluence shell. A flow guide shell is connected through the inside of one side of the water storage tank. A second filter screen is installed through the inside of the discharge shell.

[0005] Although the aforementioned patent incorporates components such as water nozzles and guide shells, allowing water stored inside the manifold to be sprayed into the cleaning shell via the water nozzles to perform multiple high-pressure water jets to clean the sand and gravel raw materials, and the water nozzles facilitate the cleaning of residual sand inside the cleaning shell after the sand washing machine has been used, and the water filtered by the second filter enters the interior of the guide shell, which guides the pre-filtered water to the interior of the water storage tank to achieve water resource recycling and reuse, it still requires the participation of clean water, and the wastewater cannot be completely graded and recycled, affecting subsequent treatment.

[0006] Therefore, this utility model provides a wastewater recycling mechanism for washing medium and coarse sand used in cement production to solve the above-mentioned problems. Utility Model Content

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.

[0019] This utility model provides a wastewater recycling mechanism for washing medium and coarse sand used in cement production, such as... Figure 1-5As shown, this wastewater recycling mechanism for washing medium and coarse sand used in cement production includes a stabilizing tank 1. A driving assembly is connected to the middle of the stabilizing tank 1, and a driving pipe 10 is driven to the output end of the driving assembly. The driving assembly can generate power to drive the driving pipe 10 to rotate periodically. A spiral box 7 is rotatably connected to the outside of the driving pipe 10. A water guide channel is provided on the spiral box 7, and the water guide channel is connected to a water guide cavity 30 located inside the spiral box 7. Wastewater enters the spiral box 7 through the driving pipe 10, and then passes through the water guide channel in the spiral box 7 for filtration. Clean water enters the water guide cavity 30, and the wastewater continues to flow downward along the water guide channel. A first separator 4 and a second separator 6 are fixedly connected to the outside of the driving assembly. The stabilizing tank 1 is divided into four spaces. One end of the spiral tank 7 extends above the first partition tank 4. The bottom of the water guiding chamber 30 is connected to a drain pipe 16 located above the space enclosed by the first partition tank 4, the second partition tank 6, and the stabilizing tank 1. Sewage enters the first partition tank 4 through the spiral tank 7, and then clean water enters the space enclosed by the first partition tank 4 and the second partition tank 6 through the drain pipe 16 to achieve separation. The second partition tank 6 is connected to a series assembly extending to this area. A circulation pump 5 is installed in the space on the other side. The bottom of the first partition tank 4 is connected to a discharge pipe 3. The top of the drive pipe 10 is connected to a deflector pipe 8 for feeding the spiral tank 7. The circulation pump 5 pumps out clean water for circulation, and the discharge pipe 3 discharges sludge to other locations.

[0020] The drive assembly includes a support box 14 fixedly connected to the stabilizing box 1. A protective box 12, fixedly connected to partition box 4 and partition box 6, is located on one side of the support box 14. A motor 13 is fixedly connected inside the protective box 12. A transmission gear 31 is driven to the output end of the motor 13. The protective box 12 protects the motor 13, reducing water corrosion. The output torque of the motor 13 is then transmitted through the transmission gear 31. A transmission unit 27 located inside the support box 14 is driven by a transmission unit 27. A movable frame 28, slidably connected to the support box 14, is rotatably connected to one side of the transmission unit 27. A transmission assembly 29, driven by the transmission gear 31, rotates the transmission unit 27 and the transmission assembly 29, further rotating the corresponding support tube 23. Both transmission unit 27 and transmission assembly 29 are adapted combinations of existing transmission shafts, bevel gears, and gears to transmit torque. A stabilizing ring 21 is rotatably connected to the outside of the support tube 23. The stabilizing ring 21 is connected to the support tube 23. A feeding pipe connected to the outside is connected to one side of the stabilizing ring 21. An inclined plate 26 is fixedly connected to one end of the transmission gear 31. A swing frame 25 is embedded on one side of the inclined plate 26. The swing frame 25 is rotatably connected to the transmission unit 27. The support tube 23 is fixedly connected to the drive tube 10. Material is fed into the stabilizing ring 21 through the feeding pipe and then enters the drive tube 10 through the corresponding space to realize the supply of raw materials. At the same time, a flexible folding rubber ring is fixedly connected to the top of the support box 14. The rubber ring is rotatably connected to the drive tube 10 to achieve the sealing and limitation of the support box 14. The support tube 23 is rotatably connected to the moving frame 28 to support the drive tube 10.

[0021] A trapezoidal tube 20 is fixedly connected inside the drive tube 10. The trapezoidal tube 20 is located on one side of the stabilizing ring 21. The cross-section of the trapezoidal tube 20 adopts a trapezoidal structure. During the periodic back-and-forth rotation of the drive tube 10, some coarse silt may accumulate in the space between the trapezoidal tube 20 and the drive tube 10. Under the action of flowing water, it will move up and down, thereby preventing silt from accumulating on the support tube 23 after the subsequent device stops working, which would affect the next use.

[0022] A drive ring is provided on the inclined plate 26. One end of the swing frame 25 adopts a spherical structure and is located inside the drive ring. The drive ring limits the spherical structure of one end of the swing frame 25, so that during the rotation of the inclined plate 26, the transmission unit 27 is driven to swing back and forth periodically, which in turn drives the drive tube 10 to swing back and forth.

[0023] The series assembly includes a siphon pipe 9 fixedly connected to the second partition box 6. The bottom of the siphon pipe 9 is connected to a drip pipe 17 extending to the bottom of the second partition box 6. After the bottom space of the drain pipe 16 is full of water, the clean water at the top of the space is siphoned into the second partition box 6 through the siphon action. After settling in the second partition box 6, the upper layer of clean water in the second partition box 6 enters the space around the circulation pump 5 for extraction and recycling.

[0024] Multiple connecting rings 11 are fixedly connected to the outside of the drive tube 10, and multiple impact pillars 18 are fixedly connected to the outside of the connecting rings 11. The impact pillars 18 are in contact with the bottom of the spiral box 7. The connecting rings 11 are expanded and are made of relatively hard rubber material. The impact pillars 18 intermittently impact the spiral box 7, thereby causing the spiral box 7 to be disturbed.

[0025] A water strip 19 is connected to one side of the diverting pipe 8, and a replenishment pipe is connected to one side of the water strip 19. Multiple filter holes are provided between the spiral box 7 and the water guiding chamber 30. The water strip 19 can replenish water to ensure the cleaning of coarse sand, and the filter holes ensure the filtration work.

[0026] Working principle: During operation, wastewater is supplied from the outside and enters the spiral box 7 through the stabilizing ring 21, drive pipe 10, and deflecting pipe 8. Then, through the guidance of the water guide channel and the filtration of the filter holes, long-term filtration is achieved. Finally, solid impurities enter the first separator 4 through the spiral box 7, while clean water enters the stabilizing box 1 through the drain pipe 16. The clean water is then siphoned by the siphon pipe 9 and settled in the second separator 6, and finally enters the other side of the stabilizing box 1. Then, it is pumped out by the circulation pump 5 and finally enters the clean water bar 19 for cleaning and circulation. During the cleaning process, the drive pipe 10 rotates back and forth periodically to achieve internal screening. In addition, the impact of the rotating impact column 18 causes vibration during the cleaning process, further ensuring the corresponding cleaning work.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
