Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a water circulation system. Background Art

[0002] In the prior art, the pyrite flotation process generally consists of: crushing → grinding → classification → beneficiation → dehydration. Ore separation is based on the principle that solid particles with different specific gravities settle at different rates in liquid. A spiral classifier is used to clean and classify the ore mixture. During the classification process, a large amount of wastewater is generated. The wastewater contains pollutants such as silt, mineral impurities, dust, and dissolved salts. In the prior art, the wastewater is discharged into a solid-liquid separation tank (sedimentation tank), where gravity sedimentation separates the solid impurities from the wastewater. The clear water on the upper layer is then pumped into the spiral classifier for secondary use.

[0003] Regarding the above-mentioned related technologies, the inventors believe that the sewage separated by sedimentation still contains a lot of water-soluble sulfides. After repeated recycling, the sulfide in the water that is easy to crystallize reaches saturation and becomes extremely easy to crystallize, resulting in the impurities after subsequent precipitation containing both silt and dissolved salts, which becomes difficult to handle. Improper handling will have an impact on the environment. In addition, under the negative pressure conditions in the water pump, the sulfide may quickly form granular crystals in the water pump, thereby affecting the normal operation of the water pump. In severe cases, it may even damage or jam the impeller of the water pump.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Summary of the Invention

[0005] In order to solve the problem that the sewage after sedimentation separation still contains a lot of water-soluble sulfides, after multiple recycling, the sulfide in the water that is easy to crystallize reaches saturation and becomes extremely easy to crystallize, resulting in the impurities after subsequent deposition containing both mud and dissolved salts, which become difficult to handle. Improper handling will have an impact on the environment, and under the negative pressure conditions in the water pump, the sulfide may quickly form granular crystals in the water pump, thereby affecting the normal operation of the water pump. In severe cases, it may even damage or jam the impeller of the water pump. The present application provides a water circulation system.

[0026] The following is combined with Figure 1-6 This application is described in further detail.

[0027] The present application embodiment discloses a water circulation system. Figure 1-2 , a water circulation system, comprising a clear water tank 1, a solid-liquid separation tank 2 and a crystallization tank 3, a water supply component 4 is installed on the side of the clear water tank 1, the solid-liquid separation tank 2 comprises a cylindrical section 201, a conical section 202 is installed on the lower side of the cylindrical section 201, a solid-liquid separation component 5 is installed on the inner side of the cylindrical section 201, the solid-liquid separation component 5 comprises a filter shaft 501 installed on the cylindrical section 201, the upper end of the filter shaft 501 passes through the cylindrical section 201 and is connected to a water outlet pipe 503, the crystallization tank 3 comprises a tank body 301 installed on the water outlet pipe 503, a rotating body 502 is installed on the upper end of the tank body 301, the rotating body 502 is communicated with the clear water tank 1, and a mud discharge component 6 is installed on the lower side of the conical section 202;

[0028] By adopting the above technical solution, after the sewage enters the spiral track, a vortex flow is formed. Under the action of inertial centrifugal force, the dissolution of sulfide crystals into the sewage is accelerated, the sludge enters the hollow ball 602, and the sewage enters the tank body 301 through the hollow shaft 5011. While collecting and treating the silt and sulfide crystals separately, the sulfide concentration in the sewage can be greatly reduced, making it difficult for sulfide to crystallize, and preventing the crystallized salt of sulfide from affecting the operation of the water pump.

[0029] Reference Figure 3-4 A freezing pipe 303 is installed at the lower end of the pool body 301. The freezing pipe 303 is composed of multiple layers of serpentine pipes that are connected in pairs and staggered and stacked. The serpentine pipes are connected in pairs. Both ends of the freezing pipe 303 pass through the pool body 301 and are connected to the external cooling water circulation equipment. Several baffles 304 are installed on the inner side of the freezing pipe 303 and the overflow pipe 302 in the pool body 301. The outlet pipe 503 is connected to the lower end of the side of the freezing pipe 303. An inclined plate 305 is installed on the outer side of the outlet pipe 503 in the freezing pipe 303.

[0030] By adopting the above technical solution, the baffle 304 is used to block the sewage overflowing into the tank body 301, thereby preventing the sewage from disturbing the sulfide crystals at the bottom. The overflowing sewage is used to exchange heat through the freezing pipe 303, so that the sulfide crystals dissolved in the sewage can be quickly crystallized. The crystallized sulfide is quickly precipitated into the tank body 301 under the action of the inclined plate 305, thereby realizing the crystallization salt treatment of the sulfide, greatly reducing the sulfide concentration in the sewage, making it difficult for the sulfide to crystallize during the subsequent transportation by the water pump, and preventing the crystallization salt of the sulfide from affecting the operation of the water pump.

[0031] Reference Figure 1-2 The water supply assembly 4 includes a water pump 401 installed outside the clean water tank 1. Two water pipes 402 are installed on the water pump 401. One water pipe 402 is connected to the clean water tank 1, and the other water pipe 402 is connected to the external spiral classifier.

[0032] By adopting the above technical solution, the sewage after filtering and crystallization treatment in the clear water tank 1 is transported to the spiral classifier through the water pump 401 through the water pipe 402, and the pyrite is graded and cleaned by the spiral classifier to achieve the recycling of sewage.

[0033] Reference Figure 5-6 The outer side of the filter shaft 501 is mounted with a rotating body 502 through a bearing, and a plurality of rotating blades 505 are mounted on the upper end of the rotating body 502. A spiral blade 504 is mounted on the outer side of the rotating body 502, and the spiral blade 504 is slidably mounted inside the cylindrical section 201 and the conical section 202;

[0034] By adopting the above technical solution, sewage is introduced into the cylindrical section 201 through the water inlet pipe 203, and the momentum of the water flow is used to drive the rotating blades 505 to rotate, causing the rotating body 502 to rotate. After the sewage enters the spiral track, a vortex flow is formed. Under the action of inertial centrifugal force, the dissolution of sulfide crystals into the sewage is accelerated, and solid particles such as silt are thrown toward the inner wall of the conical section 202. The spiral blades 504 rotate to push the silt and other solid particles to the lower end of the conical section 202 and enter the hollow ball 602. The sewage is filtered twice through the inverted cone filter cartridge 5012 and enters the tank body 301 through the hollow shaft 5011 and the outlet pipe 503. If necessary, a heating wire can be installed on the inner wall of the rotating body 502 to increase the sewage temperature and accelerate the dissolution of sulfide crystal salt in the sewage.

[0035] Reference Figure 5-6The filter shaft 501 includes a hollow shaft 5011 installed inside the cylindrical section 201, and the rotating body 502 is installed on the hollow shaft 5011 through a bearing. An inverted conical filter cartridge 5012 is installed on the inner side of the hollow shaft 5011 through a bearing. The lower end of the inverted conical filter cartridge 5012 is fixedly connected to the rotating body 502. A steel brush is installed on the outer side of the inverted conical filter cartridge 5012 in the hollow shaft 5011. A water inlet pipe 203 is installed on the side of the cylindrical section 201. The water outlet direction of the water inlet pipe 203 is tangent to the rotation direction of the spiral blade 504.

[0036] By adopting the above technical solution, the impact of the water flow is used to drive the rotating blade 505 to rotate, so that the rotating body 502 rotates, and the inverted conical filter cartridge 5012 rotates relative to the hollow shaft 5011 and the steel brush, so that the inverted conical filter cartridge 5012 can be automatically cleaned to prevent the inverted conical filter cartridge 5012 from being blocked.

[0037] Reference Figure 5-6 The mud discharge assembly 6 includes a shell 601 installed at the lower end of the conical section 202. A hollow ball 602 is installed on the inner side of the shell 601 through a bearing. A rotating shaft 603 is installed on the hollow ball 602. Discharge ports are provided at the upper and lower ends of the shell 601. A guide port adapted to the discharge port is provided on the upper side of the hollow ball 602. The end of the rotating shaft 603 passes through the shell 601 and is rotatably connected to the shell 601. A handwheel is installed on the rotating shaft 603.

[0038] By adopting the above technical solution, the rotating shaft 603 is rotated to align the guide port of the hollow ball 602 with the upper discharge port, so that the sludge settles into the hollow ball 602 for temporary storage and collection. When cleaning is required, the rotating shaft 603 is rotated to align the guide port of the hollow ball 602 with the lower discharge port, the upper discharge port is blocked, and the sludge is discharged through the guide port, making it easier to clean the sludge.

[0039] The implementation principle of a water circulation system in an embodiment of the present application is as follows: when in use, the water pump 401 is started, and the rotating shaft 603 is rotated so that the guide port of the hollow ball 602 is aligned with the discharge port on the upper side, so that the sludge is precipitated into the hollow ball 602 for temporary storage and collection, and the water in the clean water tank 1 is pumped into the water pipe 402 through the water pump 401, and the water is transported to the spiral classifier through the water pipe 402, and the pyrite is graded and cleaned by the spiral classifier, and the sewage discharged by the spiral classifier is introduced into the water inlet pipe 203 through the water pipe, and the sewage is introduced into the cylindrical section 201 through the water inlet pipe 203. The water uses the force of the water flow to drive the rotating blades 505 to rotate, causing the rotating body 502 and the spiral blades 504 to rotate, and then driving the inverted cone filter cartridge 5012 to rotate. After the sewage enters the spiral track, a vortex flow is formed. Under the action of inertial centrifugal force, the sulfide crystals are accelerated to dissolve into the sewage, and solid particles such as mud and sand are thrown to the inner wall of the conical section 202. The spiral blades 504 rotate to push the mud and sand and other solid particles to the lower end of the conical section 202, and enter the hollow ball 602 through the discharge port. The sewage passes through the inverted cone filter cartridge 5012 for secondary filtration. The hollow shaft 5011 and the outlet pipe 503 enter the tank body 301, and the baffle 304 is used to block the sewage overflowing into the tank body 301 to prevent the sewage from disturbing the sulfide crystals at the bottom. Low-temperature cooling water is introduced into the freezing pipe 303 through the external cooling water circulation equipment. The overflowing sewage exchanges heat through the freezing pipe 303, so that the sulfide crystals dissolved in the sewage can be quickly crystallized, realizing the crystallization salt treatment of sulfide, greatly reducing the sulfide concentration in the sewage, making it difficult for sulfide to crystallize during the subsequent transportation by the water pump, and thus avoiding the crystallization of sulfide. Salt affects the operation of the water pump. The crystallized sulfide is quickly precipitated into the tank body 301 under the action of the inclined plate 305. The upper clean water enters the clean water tank 1 through the overflow pipe 302, realizing the recycling of sewage. The inverted conical filter cartridge 5012 can be automatically cleaned by rotating it relative to the hollow shaft 5011 and the steel brush to prevent the inverted conical filter cartridge 5012 from being blocked. When discharging sludge, the rotating shaft 603 is rotated to align the guide port of the hollow ball 602 with the lower discharge port, and the upper discharge port is blocked. The sludge is discharged through the guide port, and the sludge cleaning is more convenient.
