Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and more specifically, to a water circulation system for aggregate wetting. Background Technology

[0002] In the mining and aggregate production industry, wet processing technology is widely used, especially in crushing and sand making. Traditional wet aggregate production systems often face problems such as high water consumption and large wastewater discharge, which not only increases production costs but also puts pressure on the environment.

[0003] In post-mining aggregate production, a three-stage crushing system consisting of jaw crushers and medium-fine cone crushers is typically used, requiring a process of less crushing and more screening to reduce the output of manufactured sand. However, manufactured sand production often employs rod milling, a process that, while offering high output, good particle shape, and simple and reliable operation, presents significant challenges in water usage and management during wet production.

[0004] Crushed aggregates are typically produced using a wet process involving two-stage screening with a circular vibrating screen, while refined sand is produced using a wet process with a rod mill. These wet production processes require large amounts of water for washing, cooling, and conveying. However, the water used often contains significant amounts of impurities such as mud and stone powder. Direct discharge of this water not only wastes water resources but also pollutes the environment. Utility Model Content

[0005] The purpose of this invention is to provide a water circulation system for aggregate wetting, in order to solve the problems of high water consumption and large wastewater discharge that traditional aggregate wet production systems often face in the background art. This not only increases production costs but also puts pressure on the environment.

[0006] To achieve the above objectives, this utility model provides a water circulation system for aggregate wetting, including a sand washing tank. A sewage pipe is connected to the bottom of one side of the sand washing tank, and a sewage tank is installed at the bottom of the sand washing tank. The outer port of the sewage pipe is located above the collection port of the sewage tank. A screen plate is installed at the collection port of the sewage tank. A waste residue separation component is installed on the top of the screen plate and below the sewage pipe. A settling tank is provided on the other side of the sand washing tank. A spray plate is connected to the top of the settling tank through a pipe. Several spray nozzles are installed on the spray plate and are located above the sand washing tank.

[0008] Preferably, a bracket is installed on the top of the waste separation assembly, and the spray plate is fixed on the bracket.

[0009] Preferably, a clean water pump is installed at the top of the settling tank. The input end of the clean water pump is connected to the inside of the settling tank through a water pipe, and the output end of the clean water pump is connected to a riser pipe. The riser pipe is connected to the inside of the spray plate through a flexible hose.

[0010] Preferably, one end of the sewage tank is connected to the top of one side of the settling tank via a sewage pump and a water pipe.

[0011] Preferably, the settling tank is provided with a filter chamber and a sedimentation chamber inside. The filter chamber is fixedly installed on the inner wall of the settling tank. There is a gap between the bottom of the filter chamber and the inner bottom wall of the settling tank. A filter screen is provided between the bottom of the filter chamber and the sedimentation chamber. A drain outlet is connected to one side of the sedimentation chamber. A valve is installed on the drain outlet. The input pipeline of the clean water pump is connected to the inside of the sedimentation chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This water circulation system for aggregate wetting effectively collects and recycles wastewater generated during the sand washing process by incorporating a sand washing tank, a wastewater tank, and a waste residue separation component. The recycled wastewater undergoes filtration and sedimentation in a settling tank to remove impurities such as mud and stone powder, making it suitable for reuse and thus reducing the amount of fresh water used in the production process.

[0015] The settling tank design effectively separates and settles impurities in the wastewater, reducing the pollutant content. The treated wastewater can then be pumped back to the spray plate for recycling, further reducing wastewater discharge. By reducing wastewater discharge and pollutant content, this water recycling system for aggregate wetting effectively controls environmental pollution. Simultaneously, the separation and recycling of waste residue reduces solid waste generation, contributing to resource conservation and environmental protection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] This invention provides a water circulation system for aggregate wetting, such as... Figures 1-3 As shown, the system includes a sand washing tank 1, which is a conventional piece of equipment in existing wet production systems. The internal sand washing structure is not described in detail. A drain pipe 11 is connected to the bottom of one side of the sand washing tank 1. A wastewater tank 4 is installed at the bottom of the sand washing tank 1. The outer port of the drain pipe 11 is located above the collection port of the wastewater tank 4. A screen plate 42 is installed at the collection port of the wastewater tank 4. A waste residue separation component 2 is installed on the top of the screen plate 42 and below the drain pipe 11. A settling tank 5 is installed on the other side of the sand washing tank 1. A spray plate 8 is connected to the top of the settling tank 5 through a pipe. The spray plate 8 has a hollow internal structure and several spray nozzles 9 are installed on the spray plate 8. The spray nozzles 9 are located above the sand washing tank 1.

[0023] In operation, the system achieves efficient water resource recycling and effective separation of waste residue through its ingenious design and layout. The connection between the sand washing tank 1 and the sewage pipe 11 allows the wastewater generated during the sand washing process to be smoothly discharged into the waste residue separation component 2 through the sewage pipe 11. The separation component 2 initially filters out larger particulate impurities in the wastewater. The screen plate 42 on the collection port of the wastewater tank 4 further refines the smaller particulate waste residue in the wastewater, ensuring the relative cleanliness of the wastewater. Initially, water can be added to the settling tank 5 so that the clean water pump 6 can draw water and deliver it to the spray plate 8, thus providing water for the sand washing process in the sand washing tank 1. At the same time, the system is also equipped with a settling tank 5 for settling the wastewater after waste residue separation. The spray plate 8 on the top of the settling tank 5 and the spray nozzles 9 installed on it achieve uniform spraying of the aggregate in the sand washing tank 1, which not only improves the sand washing efficiency but also makes full use of the water during the sand washing process.

[0024] In summary, this design enables the water circulation system for aggregate wetting of this utility model to achieve significant technical effects in terms of water resource recycling, waste separation, and sand washing efficiency, providing strong support for environmentally friendly and efficient production in the aggregate production industry.

[0025] In this embodiment, the waste residue separation component 2 includes a housing 21. The housing 21 is located at the top end of the screen plate 42. A rotating shaft 22 is rotatably mounted inside the housing 21, and a spiral blade 23 is mounted on the shaft 22. One end of the shaft 22 is driven to rotate by a motor 24. A wastewater inlet 211 is located at the top of the housing 21, below the outer port of the sewage pipe 11. A wastewater outlet 212 is located at the bottom of the housing 21, below the wastewater inlet 211. A waste residue outlet 213 is located at the bottom of the housing 21, away from the sewage pipe 11. A waste residue trough 3 is located below the waste residue outlet 213. The rotating shaft 22 is driven to rotate by the motor 24, which in turn drives the spiral blade 23, effectively separating larger particles of waste residue from the wastewater. Wastewater enters the housing 21 through the wastewater inlet 211. After separation by the spiral blade 23, relatively clean wastewater flows out through the wastewater outlet 212, while waste residue is discharged into the waste residue trough 3 through the waste residue outlet 213. This design improves wastewater treatment efficiency and ensures the smooth operation of subsequent production processes.

[0026] Specifically, a bracket 7 is installed on the top of the waste separation component 2, and the spray plate 8 is fixed on the bracket 7. This design ensures the stability of the spray plate 8, enabling accurate spraying of the aggregate in the sand washing tank 1, thus improving the uniformity and efficiency of sand washing. At the same time, the design of the bracket 7 also facilitates the maintenance and replacement of the spray plate 8.

[0027] Furthermore, a clean water pump 6 is installed at the top of the settling tank 5. The input end of the clean water pump 6 is connected to the inside of the settling tank 5 via a water pipe, and the output end of the clean water pump 6 is connected to an ascender pipe 61. The ascender pipe 61 is connected to the inside of the spray plate 8 via a flexible hose 62. This design realizes the recycling of clean water in the settling tank 5, reducing water waste. The pumping action of the clean water pump 6 ensures that clean water can be stably delivered to the spray plate 8, guaranteeing the continuity and stability of the sand washing process.

[0028] Furthermore, one end of the sewage tank 4 is connected to the top of the settling tank 5 via a sewage pump 41 and a water pipe. This design allows the sewage in the sewage tank 4 to flow smoothly into the settling tank 5 for further treatment, improving the sewage treatment efficiency. The pumping action of the sewage pump 41 ensures a stable flow of sewage, preventing sewage accumulation and blockage.

[0029] Furthermore, the settling tank 5 is internally equipped with a filter chamber 51 and a sedimentation chamber 52. The filter chamber 51 is fixedly installed on the inner wall of the settling tank 5, and there is a gap between the bottom of the filter chamber 51 and the inner bottom wall of the settling tank 5. A filter screen 521 is installed between the bottom of the filter chamber 51 and the sedimentation chamber 52. This design achieves effective filtration and sedimentation of impurities in the wastewater, improving the cleanliness of the wastewater. The interception effect of the filter screen 521 causes larger particles of impurities to be retained in the filter chamber 51, while smaller particles of impurities flow with the wastewater into the sedimentation chamber 52 for sedimentation treatment.

[0030] A drain outlet 53 is connected to one side of the sedimentation tank 52, and a valve is installed on the drain outlet 53. The input pipe of the clean water pump 6 is connected to the inside of the sedimentation tank 52, and one end of the wastewater tank 4 is connected to the top of the filter tank 51 through the wastewater pump 41 and a water pipe. This design facilitates the periodic discharge and treatment of sediment in the sedimentation tank 52, avoiding the accumulation of sediment and its impact on the normal operation of the sedimentation tank 5. The installation of the valve makes the sewage discharge process more controllable and safe.

[0031] Furthermore, a cleaning port is provided on one side of the filter chamber 51, which connects to the outside of the settling tank 5, and a cleaning cover 522 is installed at the cleaning port. This design facilitates regular cleaning and maintenance of the filter screen 521 in the filter chamber 51, ensuring the filter screen remains unobstructed and maintaining its filtration effect. The opening and closing of the cleaning cover 522 is simple and quick, improving the efficiency of maintenance work.

[0032] In use, the water circulation system for aggregate wetting of this utility model first wets the aggregate in the sand washing tank 1. The wastewater generated during the process is smoothly discharged into the waste residue separation component 2 through the drain pipe 11. The rotating shaft 22 is driven by the motor 24 to rotate, which drives the spiral blades 23 to separate larger particles of waste residue from the wastewater. The wastewater enters the outer shell 21 from the wastewater inlet 211. After being separated by the spiral blades 23, the relatively clean wastewater flows out from the wastewater outlet 212 and onto the screen plate 4, flowing into the wastewater tank 4. The screen plate 42 further separates the smaller particles of waste residue from the wastewater. The larger particles of waste residue are discharged from the waste residue outlet 213 into the waste residue tank 3 for collection and treatment.

[0033] After waste separation, the wastewater enters the filter chamber 51 for sedimentation treatment. Larger particles are intercepted by the filter screen 521 and remain in the filter chamber 51. Smaller particles flow with the wastewater into the sedimentation chamber 52 for sedimentation treatment. A clean water pump 6 at the top of the sedimentation tank 5 pumps the clean water from the sedimentation chamber 52 to the riser pipe 61, and then through the hose 62 to the spray nozzles 9 on the spray plate 8. The spray nozzles 9 evenly spray the aggregate in the sand washing tank 1, achieving the recycling of clean water and reducing water waste.

[0034] A drain port 53 is connected to one side of the sedimentation chamber 52, and a valve is installed on the drain port 53. By periodically opening the valve, the sediment in the sedimentation chamber 52 can be discharged and treated. A cleaning cover 522 is installed on one side of the filter chamber 51 to facilitate the periodic cleaning and maintenance of the filter screen 521, ensuring the unobstructed flow of the filter screen and the filtration effect.

[0035] Finally, it should be noted that the electronic components in the sewage pump 41, clean water pump 6, etc. in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.
