Description

Technical Field

[0001] This invention relates to the field of quartz sand washing wastewater recycling, and more particularly to a device for recycling and utilizing cleaning fluid used in quartz sand washing. Background Technology

[0002] In the deep processing of quartz sand, washing is a crucial step in removing surface impurities and improving its purity. Traditional washing processes typically involve repeatedly rinsing the quartz sand with large amounts of water to remove clay minerals, iron particles, and other impurities adhering to the sand grains. The wastewater generated after washing contains suspended solids, fine mud, iron filings, and other pollutants. Direct discharge of this wastewater not only wastes water resources but also creates environmental pressure. Currently, common methods for treating quartz sand washing wastewater include natural sedimentation in sedimentation tanks, filter press filtration, or coagulation sedimentation. However, these methods suffer from problems such as long treatment cycles, large equipment footprints, and low water recovery efficiency. Especially in the process of recycling cleaning fluid, existing technologies struggle to achieve rapid and continuous solid-liquid separation, resulting in a large amount of usable clean water being discharged as wastewater, increasing production costs and environmental burden. Current methods have many drawbacks: unified wastewater treatment involves large volumes and slow speeds, failing to meet the water demands of continuous production; wastewater actually contains a large amount of directly reusable clean water, which traditional methods fail to rapidly separate and reuse, leading to water waste; wastewater often contains valuable metal particles such as iron, which traditional treatment methods struggle to effectively separate and recover, resulting in resource loss; simple sedimentation or filtration cannot achieve precise stratification based on impurity particle size and specific gravity, making accurate separation of clean water, transition layers, and impurity-containing wastewater impossible.

[0003] Therefore, there is an urgent need for a device for recycling cleaning fluid used in quartz sand cleaning to solve the above problems. Summary of the Invention

[0008] Preferably, the flow guiding mechanism includes a mounting ring, a linear electric slide rail, a baffle, and a flow guide shroud; mounting rings are fixedly connected to the outer periphery of the upper side of the impurity-containing ring, and multiple sets of linear electric slide rails are evenly distributed between two mounting rings. A baffle is fixedly connected between the moving parts of each set of linear electric slide rails, and multiple baffles together block the outer open structure of the impurity-containing ring. Each baffle has an opening structure on its lower side, and a flow guide shroud communicating with the opening structure is installed on the lower side of the outer periphery of each baffle. The flow guide shroud is located inside the isolation ring.

[0009] Preferably, the output mechanism includes an output pump, a suction pipe, and an output pipe; the output pump is installed on the upper side of the central pipe, the suction pipe is installed at the suction end of the output pump and extends from the right side of the central pipe into the water purification chamber, and the output pipe is installed at the outlet end of the output pump.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] Example 1, as Figures 1-8As shown in the figure, a quartz sand cleaning fluid recycling device includes a frame 1, a fixing ring 1001, a central tube 2, a clean water tank 3, an isolation ring 4, a recycling ring 5, a centrifugal mechanism 6, a separation mechanism 7, a flow guiding mechanism 8, an output mechanism 9, an input mechanism 10, and an output mechanism 11. The fixing ring 1001, a hollow ring structure, is fixedly connected to the middle of the frame 1. The central tube 2, a flanged hollow tube structure, is also fixedly connected to the middle of the fixing ring 1001. The clean water tank 3, an annular structure, is installed in the middle of the fixing ring 1001 and is fitted around the outer circumference of the central tube 2. The clean water tank 3 is used to store the clean water after impurity removal treatment. Cleaning fluid; an isolation ring 4 is installed on the upper outer periphery of the fixed ring 1001. The isolation ring 4 is an annular chamber structure with open upper and lower sides. A recovery ring 5 is installed on the upper side of the bracket 1. The upper side of the recovery ring 5 is connected to the lower side of the isolation ring 4, and the recovery ring 5 and the isolation ring 4 are interconnected. The lower left side of the recovery ring 5 has a structure with a downward-extending discharge pipe. The isolation ring 4 and the recovery ring 5 are used to collect the impurity-containing wastewater after impurity removal treatment. A centrifugal mechanism 6 is provided on the upper side of the fixed ring 1001. The centrifugal mechanism 6 is an inverted annular bucket structure. The centrifugal mechanism 6 is rotated and fitted on the upper outer periphery of the central tube 2. The centrifugal mechanism 6 is used to separate the cleaning fluid into layers through centrifugal action, so that the cleaning fluid is separated from the impurity-containing wastewater after cleaning. The cleaning solution containing impurities after washing the sand is centrifuged in centrifuge unit 6. This centrifugal action causes the cleaning solution to form an impure wastewater layer, a particle transition layer, and a clean water layer within the centrifuge structure. Larger particles are subjected to greater centrifugal force and are located in the outer ring of centrifuge unit 6, forming the impure wastewater layer. The clean water is located in the inner ring of centrifuge unit 6, forming the clean water layer. Relatively lighter particles are subjected to less centrifugal force and are located in the middle ring of centrifuge unit 6, forming the transition layer. Multiple sets of separation mechanisms 7 are evenly distributed below the middle ring of the annular structure of centrifuge unit 6. These separation mechanisms 7 discharge the clean water that has undergone impurity separation from centrifuge unit 6. The purified water will flow into the purified water tank 3 for storage; multiple sets of guide mechanisms 8 are evenly distributed on the outer periphery of the annular structure of the centrifugal mechanism 6. The guide mechanisms 8 are used to discharge the impurity-containing wastewater and particulate transition layer wastewater that are in the outer layer after centrifugation separation at the centrifugal mechanism 6. The impurity-containing wastewater discharged through the guide mechanisms 8 will flow into the isolation ring 4 and enter the recovery ring 5; an output mechanism 9 is provided on the right side of the central pipe 2. The output mechanism 9 is used to extract the purified water in the purified water tank 3 as needed and output it to the outside for recirculation back to the quartz sand washing process; an input mechanism 10 is provided on the left side of the central pipe 2. The input mechanism 10 is used to draw in the cleaning liquid after the quartz sand is washed from the outside and input it into the centrifugal mechanism 6 for centrifugal stratification treatment;A discharge mechanism 11 is provided in the middle area of ​​the outer periphery of the fixed ring 1001. The discharge mechanism 11 is used to scrape out the wastewater containing impurities in the recovery ring 5, so that the wastewater and impurities are discharged through the discharge pipe on the left side of the recovery ring 5. At this time, the wastewater containing impurities discharged from the discharge pipe on the left side of the recovery ring 5 can be collected and filtered. The filtered water can still be returned to the quartz sand washing process. Because the wastewater filtration process is slow, a centrifugal mechanism 6 is used to centrifuge and separate the used cleaning liquid, so as to quickly recover and reuse the purified water.

[0038] like Figures 5-12As shown, the centrifugal mechanism 6 includes an annular guide rail 61, an annular electric slide rail 62, a debris-containing ring 63, a transition ring 64, a purified water ring 65, a water storage ring 66, and an input ring 67. An annular guide rail 61 is installed on the upper outer periphery of the central tube 2. An annular electric slide rail 62 is installed on the upper side of the fixed ring 1001. A debris-containing ring 63 is installed on the upper side of the moving part of the annular electric slide rail 62. The debris-containing ring 63 is a hollow annular structure with open inner and outer layers. Flow guiding mechanisms 8 are evenly distributed around the outer periphery of the debris-containing ring 63. Multiple flow guiding mechanisms 8 close the outer open portion of the debris-containing ring 63. A transition ring 64 is installed on the inner layer of the debris-containing ring 63. The transition ring 64 is a hollow structure with open inner and outer layers. The ring structure includes a transition ring 64 and a contaminated ring 63. A clean water ring 65 is installed inside the transition ring 64. The upper side of the clean water ring 65 has a uniformly distributed tempered glass structure for observing the degree of water separation within the clean water ring 65. The clean water ring 65 is a hollow ring structure with open inner and outer layers. The clean water ring 65 is interconnected with the transition ring 64. Separation mechanisms 7 are evenly distributed on the lower side of the clean water ring 65. A water storage ring 66 is installed inside the clean water ring 65. The water storage ring 66 is a hollow ring structure with an open outer layer. The outer layer of the water storage ring 66 is interconnected with the clean water ring 65. The lower inner circumference of the water storage ring 66 is connected to the moving part of the annular guide rail 61. The upper inner circumference of ring 66 has a structure with multiple water inlets. An input ring 67 is installed on the upper inner circumference of the water storage ring 66. The input ring 67 is a hollow annular structure with open upper and lower sides. The open structure on the lower side of the input ring 67 is connected to the water inlet structure of the water storage ring 66. The input mechanism 10 extends into the upper part of the input ring 67. The impurity ring 63, transition ring 64, purification ring 65, water storage ring 66 and input ring 67 are in an inverted funnel-shaped annular structure. The used cleaning fluid is input into the input ring 67 through the input mechanism 10. The cleaning fluid will be in the inverted funnel-shaped annular structure of the impurity ring 63, transition ring 64, purification ring 65, water storage ring 66 and input ring 67. Within the structure, the annular electric slide rail 62 is activated simultaneously, which drives the centrifugal mechanism 6 to rotate. By controlling the rotation speed of the annular electric slide rail 62, the water in the centrifugal mechanism 6 is subjected to centrifugal force, causing large particles of impurities in the water to be thrown to the outer layer of the impurity-containing ring 63 under greater centrifugal force. This causes the water in the clean water ring 65 and the water storage ring 66 to form a clean water layer. Since the impurity content of different batches of cleaning solution is different, the water in the impurity-containing ring 63, transition ring 64 and clean water ring 65 area will form a transition layer. By observing the tempered glass layer on the upper side of the clean water ring 65, the separation mechanism 7 can be controlled to discharge the clean water in the clean water ring 65 layer.

[0039] like Figures 11-12As shown, the separation mechanism 7 includes a release pipe 71 and a solenoid valve 72. The lower side of the clean water ring 65 has different separation radii at its outer periphery, middle, and inner periphery. Multiple release pipes 71 with different separation radii are evenly distributed within the three rings at the outer periphery, middle, and inner periphery of the lower side of the clean water ring 65. The release pipes 71 all extend into the clean water ring 65, so that the release pipes 71 at different separation radii can discharge clean water at different radius layers within the clean water ring 65, thus avoiding the transition layer after different batches of cleaning liquid have passed through the separation, and ensuring that the water discharged by the release pipes 71 does not contain the transition layer. A solenoid valve 72 is installed at each release pipe 71, and the solenoid valves 72 connected to each release pipe 71 at the same separation radius are uniformly controlled.

[0040] like Figures 13-15 As shown, the flow guiding mechanism 8 includes mounting rings 81, linear electric slide rails 82, baffles 83, and flow guide covers 84. Mounting rings 81 are fixedly connected to the outer periphery of the upper side of the impurity-containing ring 63. Multiple sets of linear electric slide rails 82 are evenly distributed between two mounting rings 81. Each set of linear electric slide rails 82 consists of two opposite positions. These multiple sets of linear electric slide rails 82 are controlled uniformly. Baffles 83 are fixedly connected between the moving parts of each set of linear electric slide rails 82. These multiple baffles 83 collectively block the outer open structure of the impurity-containing ring 63. The lower side of each baffle 83 has an opening. A flow guide shroud 84 is installed on the lower outer periphery of each plate 83. The flow guide shroud 84 is interconnected with the opening structure of the corresponding baffle 83. The flow guide shroud 84 is used to guide the discharged wastewater containing impurities downward into the isolation ring 4 and the recovery ring 5. The flow guide shroud 84 is located inside the isolation ring 4. When the linear electric slide rail 82 is activated, the linear electric slide rail 82 will drive the baffle 83 to move upward, so that the opening structure of the baffle 83 corresponds to the outer open structure of the impurity ring 63 and the flow guide shroud 84, so that the wastewater containing impurities in the impurity ring 63 flows into the isolation ring 4 from the opening structure of the baffle 83 through the flow guide shroud 84.

[0041] like Figure 5 As shown, the output mechanism 9 includes an output pump 91, a suction pipe 92, and an output pipe 93. The output pump 91 is installed on the upper side of the central pipe 2. The suction pipe 92 is installed at the suction end of the output pump 91. The suction pipe 92 extends from the right side of the central pipe 2 and enters the clean water chamber 3. The output pipe 93 is installed at the outlet end of the output pump 91. The output pipe 93 has a docking valve structure, which allows external pipes to be installed at the output pipe 93 and connected to the water supply pipeline of the quartz sand washing process, so that the clean water in the clean water chamber 3 can re-enter the circulation of the quartz sand washing process.

[0042] like Figure 5As shown, the input mechanism 10 includes an input pump 101, a connecting pipe 102, and an input pipe 103. The input pump 101 is installed on the lower side of the central pipe 2. The connecting pipe 102 is installed at the suction end of the input pump 101. The connecting pipe 102 is a docking valve structure, which can install external pipes at the connecting pipe 102 and connect the external pipes to the drainage pipe of the quartz sand washing process, so that the used cleaning liquid generated in the quartz sand washing process can enter the circulation processing operation of the centrifugal mechanism 6. The input pipe 103 is installed at the outlet end of the input pump 101. The input pipe 103 extends from the upper left side of the central pipe 2. The upper part of the input pipe 103 is an inverted U-shaped structure suspended in the upper position inside the input ring 67.

[0043] like Figure 17 As shown, the discharge mechanism 11 includes an annular drive slide rail 111 and a scraper 112. The annular drive slide rail 111 is installed in the middle of the outer periphery of the fixed ring 1001. The annular drive slide rail 111 is electrically controlled. The scraper 112 is fixedly connected to the moving part of the annular drive slide rail 111. The lower side and left and right edges of the scraper 112 are in contact with the inner periphery of the recovery ring 5. When the annular drive slide rail 111 is activated, the annular drive slide rail 111 will drive the scraper 112 to rotate in the recovery ring 5, thereby scraping the wastewater containing impurities and sediment that are discharged into the recovery ring 5 into the discharge pipe on its left side and discharged to the outside.

[0044] like Figures 6-8 As shown, it also includes a magnetic separation mechanism 12, which includes an adsorption plate 121 and an electromagnet 122. The magnetic separation mechanism 12 is located on the outer periphery of the impurity-containing ring 63. The magnetic separation mechanism 12 is used by the centrifugation mechanism 6 to pre-adsorb iron impurities when centrifuging the cleaning liquid to improve the recovery rate of valuable metals in the cleaning liquid. The adsorption plates 121 are embedded and evenly distributed on the upper side of the impurity-containing ring 63, and electromagnets 122 are installed on the upper side of each adsorption plate 121. Multiple electromagnets 122 are controlled uniformly. When the electromagnet 122 is activated... 22. When the centrifuge mechanism 6 centrifuges and separates the cleaning liquid, the electromagnet 122 and the adsorption plate 121 adsorb iron impurities. When the wastewater containing impurities is discharged through the discharge mechanism 11, the impurities that are not adsorbed will be directly discharged to the recovery ring 5. After the discharge mechanism 11 scrapes off such impurities, the electromagnet 122 can be turned off, so that the adsorbed iron impurities are discharged to the recovery ring 5. The valuable metals are then scraped off and subsequently recovered by the discharge mechanism 11, thereby improving the recovery rate of valuable metals in the wastewater containing impurities.

[0045] like Figure 3As shown, it also includes a monitoring mechanism 13, which includes a connecting frame 131 and turbidity sensors 132. The connecting frame 131 is installed on the upper left side of the central tube 2, and multiple turbidity sensors 132 are installed on the lower side of the connecting frame 131. The turbidity sensors 132 correspond to the release pipes 71 at different separation radii. The turbidity sensors 132 are photoelectric. When the turbidity sensors 132 are activated, they can monitor the turbidity of the water in each different separation radius, thereby determining the location of the purified water layer that can be released into the purified water chamber 3. Based on the determined location of the purified water layer, the release pipe 71 at the location of the purified water layer and its connected solenoid valve 72 are precisely controlled to start, thereby accurately releasing purified water.

[0046] Example 2, as Figures 1-17 As shown, the working process of the quartz sand washing liquid recycling device can be divided into four continuous steps: water inlet stage, centrifugal separation stage, purified water release stage, and slag discharge stage.

[0047] Phase 1: Water Intake; The input pump 101 is started, and the used cleaning fluid containing impurities is drawn from the drainage pipe of the quartz sand washing process through the connecting pipe 102. The cleaning fluid is transported through the input pipe 103 and enters the input ring 67 from the inverted U-shaped structure on the upper side of the input pipe 103. The cleaning fluid flows into the water storage ring 66, the clean water ring 65, the transition ring 64 and the impurity ring 63 in sequence, filling the entire centrifugal mechanism 6.

[0048] Second stage: Centrifugal separation; The annular electric slide rail 62 is activated, driving the entire centrifugal mechanism 6 to rotate, including the impurity ring 63, transition ring 64, clean water ring 65, water storage ring 66, and input ring 67. The rotation speed of the annular electric slide rail 62 is typically set within the range of 300-800 rpm, so that the centrifugal force reaches the set separation factor. Under the action of centrifugal force: iron-containing micro powder and large particulate impurities are thrown to the outer layer of the impurity ring 63; fine suspended particles gather in the transition ring 64 area; and clean water is located in the inner ring area of ​​the clean water ring 65 and the water storage ring 66. At the same time, the electromagnet 122 of the magnetic separation mechanism 12 is energized, and the adsorption plate 121 adsorbs the iron-containing micro powder in the impurity ring 63 area.

[0049] Phase Three: Purified Water Release and Reuse; The turbidity sensor 132 of the monitoring agency 13 detects the turbidity of the water at each separation radius in real time; the control system determines the radius range of the clean water layer of the current batch of wastewater based on the turbidity data; the control system only opens the solenoid valve 72 at the corresponding radius position, so that the release pipe 71 at that radius is opened, allowing the clean water to flow into the clean water chamber 3 for storage through the release pipe 71; the separation effect can be observed through the tempered glass structure on the upper side of the clean water ring 65, and manual intervention can be performed when necessary; when the quartz sand washing process needs to replenish water, the output pump 91 is started, and the clean water in the clean water chamber 3 is drawn through the suction pipe 92 and transported back to the water supply pipeline of the washing process through the output pipe 93.

[0050] Phase 4: Discharge and treatment of wastewater containing impurities; The linear electric slide rail 82 is activated, driving the baffle 83 to move upward, aligning the opening structure on the lower side of the baffle 83 with the outer open structure of the impurity-containing ring 63; the impurity-containing wastewater in the impurity-containing ring 63 and the transition layer wastewater in the transition ring 64 flow into the guide hood 84 through the opening of the baffle 83; the wastewater flows downward through the guide hood 84 into the isolation ring 4, and then into the recovery ring 5; the annular drive slide rail 111 is activated, driving the scraper 112 to rotate within the recovery ring 5, and the scraper 112 scrapes the impurity-containing wastewater and sediment impurities in the recovery ring 5 to the left discharge pipe, and the impurity-containing wastewater is discharged out of the device through the discharge pipe and enters the subsequent pressure filtration process.

[0051] Phase 5: Iron powder recovery; During the regular slag discharge process, the electromagnet 122 remains energized, adsorbing iron powder and temporarily storing it on the adsorption plate 121. After the non-magnetic impurities are discharged, the power supply to the electromagnet 122 is turned off, and the iron powder on the adsorption plate 121 loses its magnetic attraction and is discharged into the recovery ring 5 with a small amount of flushing water. The discharge mechanism 11 scrapes the iron powder to the discharge pipe, realizing the separate recovery of valuable metals.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
