Description

Technical Field

[0001] This invention relates to the field of wastewater collection technology, and in particular to a wastewater collection tank for photovoltaic quartz sand raw material production. Background Technology

[0002] Photovoltaic quartz sand is a high-purity siliceous raw material obtained from natural quartz minerals such as quartzite, vein quartz, and quartz sandstone through physical and chemical purification processes. It generally involves processes such as mining, crushing, washing, magnetic separation and flotation, acid leaching, high-temperature calcination, and cleaning and drying. Therefore, wastewater is generated in the entire process, especially in the acid leaching and cleaning stages. Some of the wastewater has strong polluting characteristics such as containing fluoride, acids and alkalis, and heavy metals. Common wastewater treatment methods include neutralization, precipitation, and membrane treatment.

[0003] Existing patent CN200410039183.4 discloses a sleeve-type variable-velocity vortex combined reactor and a high-efficiency composite sedimentation tank. The sedimentation tank has an outlet trough at the top, a clarification zone in the middle, and a sludge discharge pipe at the bottom. The sleeve-type variable-velocity vortex combined reactor is vertically installed inside the sedimentation tank. This combined reactor consists of a cylindrical outer cylinder and a concentric concentric inner cylinder. The inner cylinder is a tapered inner cylinder with a diameter that is wider at the bottom than the top. The lower end of the tapered inner cylinder is connected to an outlet diffuser extending from the outer cylinder, and the upper end of the tapered inner cylinder is submerged in the outer cylinder and houses an inner cylinder agitator. The lower part of the outer cylinder is tangentially connected to the inlet and dosing pipes. The outlet diffuser is funnel-shaped. A vortex guide is connected at the connection between the inlet and dosing pipes and the lower part of the outer cylinder, and this vortex guide creates a tangential upward vortex. It solves the technical problems of slow fluid mixing, reaction, flocculation, and sludge discharge, high energy consumption, and poor mixing uniformity, and can be used for wastewater and reclaimed water purification treatment.

[0004] Regarding the sedimentation process, the above structure can achieve sedimentation. However, during the production of photovoltaic quartz sand raw materials, when collecting wastewater, the high water flow velocity and impact force can easily cause the already settled sludge to be resuspended, affecting the sedimentation efficiency. Furthermore, after the sludge settles, it needs to be discharged. However, the sludge is dispersed at the bottom and is difficult to discharge quickly, leading to sludge accumulation and affecting the sludge discharge efficiency, thereby affecting the overall operating efficiency of the wastewater treatment system.

[0005] Therefore, how to provide a wastewater collection tank for photovoltaic quartz sand raw material production is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One objective of this invention is to provide a wastewater collection tank for photovoltaic quartz sand raw material production.

The component includes a push-pull assembly between the buoyancy assembly and the flow guiding assembly, and a scraping assembly for scraping sludge on the flow guiding assembly. When wastewater is added, the buoyancy assembly moves upward, causing the push-pull assembly to move downward and push the flow guiding assembly, resulting in a first state where the upper part of the flow guiding assembly converges towards the center, achieving a wastewater flow guiding effect. When sludge is discharged, the buoyancy assembly moves downward, causing the push-pull assembly to move upward and pull the flow guiding assembly, resulting in a second state where the lower part of the flow guiding assembly converges towards the center, achieving a sludge aggregation effect.

[0007] Preferably, the conveying assembly includes a support rod disposed inside the wastewater tank, a funnel disposed on the support rod, and a conveying pipe disposed on the support rod penetrating the wastewater tank. One end of the conveying pipe is connected to the wastewater conveying system, and the other end of the conveying pipe is located above the funnel.

[0008] Preferably, the buoyancy assembly includes a support frame disposed within the wastewater tank, a float rod extending through the support frame, a float ball disposed on the float rod, and a mounting plate disposed on the float rod.

[0009] Preferably, the pressing assembly includes a pressing outer rod disposed inside the wastewater tank, a connecting plate disposed on the float, a pressing inner rod disposed on the connecting plate that penetrates the pressing outer rod, and a pressing spring disposed between the connecting plate and the pressing outer rod, which is sleeved on the outer ring of the pressing inner rod.

[0010] Preferably, the water-dividing assembly includes a water-dividing cone disposed on the float, the float passing through the water-dividing cone, and a plurality of evenly distributed water-dividing baffles disposed on the water-dividing cone.

[0011] Preferably, the buffer assembly includes a buffer cylinder disposed on the mounting plate, a buffer piston disposed inside the buffer cylinder, a buffer rod disposed on the buffer piston that passes through the buffer cylinder and the mounting plate, the buffer rod being connected to the water-dividing cone, and a buffer spring sleeved on the outer ring of the buffer rod being disposed between the mounting plate and the water-dividing cone.

[0012] Preferably, the energy-absorbing component includes an energy-absorbing cylinder disposed on the buffer cylinder, the energy-absorbing cylinder being provided with an air inlet pipe and an air outlet pipe, the energy-absorbing cylinder and the buffer cylinder being connected through the air inlet pipe and the air outlet pipe, and the diameter of the air inlet pipe being larger than the diameter of the air outlet pipe.

[0013] Preferably, the flow guiding assembly includes a mounting rod hinged around the wastewater tank, and a flow guiding plate is provided on the mounting rod, the upper and lower parts of which are arc-shaped.

[0014] Preferably, the push-pull assembly includes a fixing frame disposed on the inner wall of the wastewater tank, a connecting rod hinged to the fixing frame, one end of the connecting rod hinged to the mounting plate, and the other end of the connecting rod hinged to a push-pull rod, which is hinged to the guide plate.

[0015] Preferably, the scraping assembly includes a rod disposed at the bottom of the guide plate, a scraping plate disposed on the rod, and a scraper for collecting sludge mounted on the scraping plate.

[0016] The beneficial effects of this invention are as follows: In this invention, when collecting wastewater, the conveying component is connected to the wastewater conveying system. The wastewater is conveyed to the water distribution component through the conveying component. The water distribution component is subjected to the impact force of the wastewater, which acts on the buffer component, causing the buffer component to press down. The energy-absorbing component absorbs the energy of the buffer component, thereby achieving a buffering effect against the impact force of the wastewater. At the same time, the water distribution component disperses the wastewater to the surrounding area, forcing the wastewater to be evenly dispersed on the flow guiding component. Under the action of the flow guiding component, the wastewater is forced to flow evenly into the wastewater tank. After a period of time, the wastewater gradually settles and separates into layers. At this time, the wastewater does not completely fill the wastewater tank. When the liquid surface contacts the buoyancy component, the buoyancy component generates buoyancy. The buoyancy component overcomes the downward pressure of the pressure-reducing component, causing it to move upwards. This upward movement drives the buffer, energy-absorbing, and water-distributing components to move upwards as well. Simultaneously, the buoyancy component moves the push-pull component, causing one end of the push-pull component to move upwards and the other end downwards. This forces the push-pull component to push the flow guide component downwards, causing the upper part of the flow guide component to converge towards the center, forming an umbrella-like structure. When wastewater continues to be released, it flows smoothly through the water-distributing component to the flow guide component. Because the flow guide component forms an umbrella-like structure, the wastewater slowly flows down to the bottom of the wastewater tank, effectively preventing subsequent wastewater from impacting the sludge at the bottom of the tank and avoiding secondary sludge formation. The process continues until the wastewater fills the standard line of the wastewater tank. After sedimentation, the upper layer of water is drained through the drain pipe. Due to the reduction in the total amount of wastewater, the buoyancy component moves downward, causing the buffer component, energy absorption component, and water distribution component to move downward as well. The pressure component slowly returns to its original state. Simultaneously, the buoyancy component drives the push-pull component, causing one end of the push-pull component to move downward and the other end to move upward. This forces the push-pull component to pull the flow guide component upward, causing the upper part of the flow guide component to move outward while the lower part moves towards the center, forming an inverted umbrella-shaped structure. This forces the flow guide component to drive the scraping component, causing the bottom sludge to slowly move towards the center. The sludge is brought closer together until the upper layer of water is discharged to a reasonable level. Then, the sludge discharge pipe is opened, and the sludge and a small amount of water are discharged simultaneously through the sludge discharge pipe, so that the sludge is discharged quickly and sludge accumulation is avoided. In summary, the wastewater collection tank for photovoltaic quartz sand raw material production of this application can buffer the impact force of wastewater and reduce the impact effect. At the same time, it uses buoyancy to guide the wastewater to the bottom of the wastewater tank, avoiding secondary suspension of sludge and improving sedimentation efficiency. After the sludge settles, the discharge of the upper layer of water can achieve the sludge gathering effect, so that the sludge is released quickly and sludge does not accumulate at the bottom of the wastewater tank, thus improving the sludge discharge efficiency and improving the overall operating efficiency of the wastewater treatment system.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a wastewater collection tank for photovoltaic quartz sand raw material production according to the present invention includes a wastewater tank body 1, a drain pipe 2 and a sludge discharge pipe 3 installed on the wastewater tank body 1. The drain pipe 2 is located at a reasonable center position of the wastewater tank body 1, and the sludge discharge pipe 3 is located at the bottom center position of the wastewater tank body 1. A conveying assembly 4 for conveying wastewater is installed on the wastewater tank body 1 and is connected to a wastewater conveying system. A pressure-reducing assembly 5 is installed inside the wastewater tank body 1 and is located at the top of the wastewater tank body 1. A buoyancy assembly 6 connected to the pressure-reducing assembly 5 is installed inside the wastewater tank body 1 and is located on the central axis of the wastewater tank body 1. A water-distributing assembly 7 is installed on the buoyancy assembly 6 and has the function of dispersing wastewater. A buffer assembly 8 is installed between the water-distributing assembly 7 and the buoyancy assembly 6, and an energy-absorbing assembly 9 is installed on the buffer assembly 8. The buffer assembly 8 and the energy-absorbing assembly 9 are used in conjunction. To achieve a buffering effect, a flow guiding component 10 is installed inside the wastewater tank 1. The flow guiding component 10 can rotate. A push-pull component 11 is installed between the buoyancy component 6 and the flow guiding component 10. The push-pull component 11 uses the lever principle to achieve the downward pushing and upward pulling effects. A scraping component 12 for scraping sludge is installed on the flow guiding component 10. The scraping component 12 is located between the flow guiding component 10 and the bottom of the wastewater tank 1. When wastewater is added, the buoyancy component 6 moves upward, causing the push-pull component 11 to move downward and push the flow guiding component 10, so that the flow guiding component 10 moves to the first state, causing the upper part of the flow guiding component 10 to converge towards the center, achieving the flow guiding effect of wastewater. When sludge is discharged, the buoyancy component 6 moves downward, causing the push-pull component 11 to move upward and pull the flow guiding component 10, so that the flow guiding component 10 moves to the second state, causing the lower part of the flow guiding component 10 to converge towards the center, achieving the sludge aggregation effect.

[0022] Working Principle: When collecting wastewater, the conveying component 4 is connected to the wastewater conveying system. The wastewater is conveyed through the conveying component 4 to the water distribution component 7. The water distribution component 7 is subjected to the impact force of the wastewater, which acts on the buffer component 8, causing the buffer component 8 to press down. The energy absorption component 9 absorbs the energy of the buffer component 8, thereby achieving a buffering effect against the impact force of the wastewater. At the same time, the water distribution component 7 disperses the wastewater to the surrounding area, forcing the wastewater to be evenly distributed on the flow guiding component 10. Under the action of the flow guiding component 10, the wastewater is forced to be evenly released into the wastewater tank 1. After a period of time, the wastewater gradually settles and separates into layers. At this time, the wastewater does not completely fill the wastewater tank 1. When the liquid surface contacts the buoyancy component 6, the buoyancy component 6 will generate buoyancy. The buoyancy component 6 overcomes the downward pressure of the downward pressure component 5, causing the buoyancy component 6 to move upward. The buoyancy component 6 then drives the buffer component 8, energy absorption component 9, and water distribution component 7 to move upward. Simultaneously, the buoyancy component 6 drives the push-pull component 11, causing one end of the push-pull component 11 to move upward and the other end downward, forcing the push-pull component 11 to push the flow guide component 10 downward. This forces the upper part of the flow guide component 10 to move towards the center, forming an umbrella-shaped structure. When wastewater continues to be released, the wastewater flows smoothly through the water distribution component 7 to the flow guide component 10. Because the flow guide component 10 forms an umbrella-shaped structure, the wastewater slowly flows down to the bottom of the wastewater tank 1, effectively preventing subsequent wastewater from impacting the bottom of the wastewater tank 1. Sludge is removed to prevent secondary suspension until the wastewater fills the standard line of wastewater tank 1. After sedimentation, the upper layer of water is discharged through drain pipe 2. Due to the reduction in the total amount of wastewater, buoyancy component 6 moves downward, causing buffer component 8, energy absorption component 9, and water distribution component 7 to move downward as well. Pressure component 5 slowly returns to its original state. At the same time, buoyancy component 6 causes push-pull component 11 to move, with one end of push-pull component 11 moving downward and the other end moving upward. This forces push-pull component 11 to pull guide component 10 upward, causing the upper part of guide component 10 to move outward while the lower part of guide component 10 moves towards the center, forming an inverted umbrella-shaped structure. This forces guide component 10 to drive scraping component 1. 2. Movement forces the bottom sludge to slowly move towards the center until the upper layer of water is discharged to a reasonable state. Then, the sludge discharge pipe 3 is opened, and the sludge and a small amount of water are discharged simultaneously through the sludge discharge pipe 3, so that the sludge is discharged quickly and sludge accumulation is avoided. In summary, the wastewater collection tank for photovoltaic quartz sand raw material production of this application can buffer the impact force of wastewater and reduce the impact effect. At the same time, it uses buoyancy to guide the wastewater to the bottom of the wastewater tank 1, avoiding secondary suspension of sludge and improving sedimentation efficiency. After the sludge settles, the discharge of the upper layer of water can achieve the sludge aggregation effect, so that the sludge is released quickly and sludge is not accumulated around the bottom of the wastewater tank 1, improving the sludge discharge efficiency and thus improving the overall operating efficiency of the wastewater treatment system.

The conveying assembly 4 includes a support rod 401 disposed inside the wastewater tank 1. The support rod 401 is composed of a horizontal rod and a vertical rod. A funnel 402 is disposed on the support rod 401. The funnel 402 has a large opening at the top and a small opening at the bottom. A conveying pipe 403 is disposed on the support rod 401, penetrating the wastewater tank 1. One end of the conveying pipe 403 is connected to the wastewater conveying system, and the other end of the conveying pipe 403 is located above the funnel 402.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention discloses a wastewater collection tank for photovoltaic quartz sand raw material production. The buoyancy component 6 includes a support frame 601 disposed inside the wastewater tank body 1. The support frame 601 is arranged in a cross shape to improve stability.

The pressure outer rod 501 is disposed along the central axis of the wastewater tank body 1 and is in a vertically downward state. A connecting plate 502 is disposed on a float 602. A pressure inner rod 503 is disposed on the connecting plate 502 and passes through the pressure outer rod 501. The pressure inner rod 503 can slide on the pressure outer rod 501. A pressure spring 504 is disposed between the connecting plate 502 and the pressure outer rod 501 and is sleeved on the outer ring of the pressure inner rod 503. When the float 603 moves upward, it overcomes the elastic force of the pressure spring 504.

The water distribution baffles 702 are perpendicular to the water distribution cone 701.

The energy absorption cylinder 901 is provided with an air inlet pipe 902 and an air outlet pipe 903. The energy absorption cylinder 901 and the buffer cylinder 801 are connected through the air inlet pipe 902 and the air outlet pipe 903. The diameter of the air inlet pipe 902 is larger than the diameter of the air outlet pipe 903.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides a wastewater collection tank for photovoltaic quartz sand raw material production. The flow guiding component 10 includes an installation rod 1001 hinged around the wastewater tank body 1. The installation rod 1001 can rotate in the vertical direction. A flow guiding plate 1002 is provided on the installation rod 1001. The upper and lower parts of the flow guiding plate 1002 are both arc-shaped.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a wastewater collection tank for photovoltaic quartz sand raw material production according to the present invention includes a push-pull assembly 11 comprising a fixed frame 1101 disposed on the inner wall of the wastewater tank 1. The fixed frame 1101 is L-shaped, and a connecting rod 1102 is hinged to the fixed frame 1101. An active space is reserved between the fixed frame 1101 and the connecting rod 1102. This active space is mainly to ensure that the connecting rod 1102 can follow the movement normally when the mounting plate 604 moves up and down, avoiding movement interference. The center of the connecting rod 1102 is hinged to the fixed frame 1101, one end of the connecting rod 1102 is hinged to the mounting plate 604, and the other end of the connecting rod 1102 is hinged to a push-pull rod 1103. The push-pull rod 1103 forms an angle with the connecting rod 1102 and is hinged to the guide plate 1002.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the wastewater collection tank for photovoltaic quartz sand raw material production of the present invention includes a scraping assembly 12 comprising a hanging rod 1201 disposed at the bottom of a guide plate 1002, the hanging rod 1201 having a fixing function, a scraping plate 1202 disposed on the hanging rod 1201, the scraping plate 1202 being arc-shaped, multiple arc-shaped plates converging to be in contact, and a scraper 1203 for aggregating sludge being mounted on the scraping plate 1202, the scraper 1203 being located at the bottom of the arc-shaped plate.

[0032] Working principle: When collecting wastewater, the conveying pipe 403 is connected to the wastewater conveying system. Wastewater is conveyed through the conveying pipe 403 and collected and discharged into the water-distributing cone 701 through the funnel 402. The water-distributing cone 701 disperses the wastewater, allowing it to flow through the space between the water-distributing baffle 702 and the water-distributing cone 701 to the guide plate 1002. The water-distributing cone 701 is subjected to the impact force of the wastewater, which acts on the buffer rod 803. This causes the buffer rod 803 to drive the buffer piston 802 to move within the buffer cylinder 801, compressing the buffer spring 804 and increasing the gas pressure within the buffer cylinder 801. The gas is introduced into the energy-absorbing cylinder 901 through the air inlet pipe 902 and discharged into the buffer cylinder 801 through the air outlet pipe 903. Since the diameter of the air inlet pipe 902 is larger than the diameter of the air outlet pipe 903, the gas discharge speed is slow, which consumes the energy of the buffer spring 804, making the rebound effect of the buffer spring 804 small, thus achieving the effect of absorbing energy and buffering the impact force of wastewater. At the same time, the wastewater is guided to the bottom and surrounding area of ​​the wastewater tank 1 through the guide plate 1002, forcing the wastewater to be evenly dispersed in the wastewater tank 1. After a period of time, the wastewater gradually settles and separates into layers. At this time, the wastewater does not fill the wastewater tank 1. When the liquid surface contacts the float 603, the float 603 generates buoyancy, causing it to move upward and drive the float rod 602 upward, overcoming the force of the downward pressure spring 504. The float rod 602 then drives the connecting plate 502 and the inner downward pressure rod 503 upward, causing the inner downward pressure rod 503 to slide within the outer downward pressure rod 501, thus compressing the downward pressure spring 504. Simultaneously, the float rod 602 drives the mounting plate 604 upward, forcing the buffer assembly 8, energy absorption assembly 9, and water distribution assembly 7 to move upward. The upward movement of 604 causes the end of the connecting rod 1102 to move upward. Under the action of the fixing frame 1101, the other end of the connecting rod 1102 moves downward, causing the connecting rod 1102 to drive the push-pull rod 1103 to move downward. This forces the push-pull rod 1103 to act on the upper part of the guide plate 1002. Under the action of the mounting rod 1001, the upper part of the guide plate 1002 rotates inward around the hinge point of the mounting rod 1001, forcing the upper part of the guide plate 1002 to move towards the center, forming an umbrella-shaped structure. When wastewater continues to be released, the wastewater flows smoothly through the water-dividing baffle 702 and the water-dividing cone 701 to the guide plate 1002. Since the guide plate 1002 forms an umbrella-shaped structure, the wastewater slowly flows down to the bottom of the wastewater tank 1, thereby effectively preventing the subsequent wastewater from impacting the sludge at the bottom of the wastewater tank 1 and preventing the sludge from being suspended again, until the wastewater fills the standard line position of the wastewater tank 1. After sedimentation, the upper layer of water is drained through drain pipe 2. Due to the reduction in the total amount of wastewater, the float 603 moves downward, causing the float rod 602 to move downward. The float rod 602 then moves the connecting plate 502 and the inner pressing rod 503 downward, causing the inner pressing rod 503 to slide within the outer pressing rod 501. This causes the pressing spring 504 to stretch and return to its original state. Simultaneously, the float rod 602 moves the mounting plate 604 downward, forcing the buffer assembly 8, energy absorption assembly 9, and water distribution assembly 7 to move downward. At the same time, the downward movement of the mounting plate 604 causes the end of the connecting rod 1102 to move downward. Under the action of the fixing frame 1101, the other end of the connecting rod 1102 moves upward, causing the connecting rod 1102 to move the push-pull rod 1103 upward, forcing the push-pull rod 1103 to act on the guide plate 1002. The upper part of the guide plate 1002 is pulled up. Under the action of the mounting rod 1001, the upper part of the guide plate 1002 rotates outward around the hinge point of the mounting rod 1001, forcing the lower part of the guide plate 1002 to move towards the center, forming an inverted umbrella-shaped structure. This forces the guide plate 1002 to drive the hanging rod 1201 to move, the hanging rod 1201 to drive the scraper 1202 to move, and the scraper 1202 to drive the scraper 1203 to move. As the lower part of the guide plate 1002 moves towards the center, the scraper 1202 and the scraper 1203 are forced to slowly move the bottom sludge towards the center until the upper water is discharged to a reasonable state. Then, the sludge discharge pipe 3 is opened, and the sludge and a small amount of water are discharged simultaneously through the sludge discharge pipe 3, so that the sludge is discharged quickly and sludge accumulation is avoided.

[0033] This solution can buffer the impact of wastewater, reduce the impact effect, and use buoyancy to guide the wastewater to the bottom of wastewater tank 1, avoiding secondary suspension of sludge and improving sedimentation efficiency. On the other hand, after the sludge settles, the upper layer of water can be discharged to achieve the effect of sludge aggregation, so that the sludge can be released quickly, avoiding the accumulation of sludge around the bottom of wastewater tank 1, improving the sludge discharge efficiency, and thus improving the overall operating efficiency of the wastewater treatment system.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
