Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a structure for a photovoltaic glass edge-grinding water-preventing sedimentation wastewater tank. Background Technology

[0002] Photovoltaic glass edging water is a coolant used in photovoltaic glass processing (edging process). The medium is usually water. During the edging process, the friction between the glass and the grinding wheel generates a lot of heat. The edging water needs to quickly remove the heat to prevent the glass from cracking or deforming due to local overheating. At the same time, it protects the grinding wheel from overheating and wear. In the edging process, it can reduce frictional resistance, reduce the generation of defects such as scratches and chipping on the glass surface, and ensure that the glass edge is smooth after edging.

[0003] In the deep processing of photovoltaic glass, the water supply for the edge grinding machine adopts a circulating water supply method. The wastewater produced in the edge grinding process enters the edge grinding water treatment system and is treated by physical / chemical methods to ensure that the SS value in the water meets the requirements of the edge grinding process.

[0004] Existing technical problems:

[0005] Cleaning glass powder from the bottom of the water tank is difficult: the glass powder produced by edge grinding has a density greater than water. If the water suspension performance of the edge grinding is insufficient (such as the additive is ineffective), the water circulation speed is slow, or the water tank is not cleaned in time, the glass powder will gradually settle. After long-term accumulation, the fine particles agglomerate into sediment that easily settles and clumps in the water, especially at the bottom of the sewage collection tank. Initially, it may be loose sediment, but if it is not treated in time, as new glass powder continues to accumulate, the clump will become thicker and tighter. The bottom of the collection tank / sedimentation tank / concentration tank gradually settles, causing the sludge scraper and agitator in the water treatment system to be obstructed, affecting the normal operation of the water treatment system. Cleaning is difficult and consumes a lot of manpower and resources. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention proposes a wastewater tank that can prevent sediment from settling and hardening at the bottom.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a structure for a photovoltaic glass edging water anti-sedimentation sewage tank, characterized in that it includes a tank body, the bottom of which has a slope, an aeration pipe rotatably connected at the lowest point of the tank bottom, a sleeve rotatably connected to the outside of the aeration pipe, the sleeve having a spiral through groove, a traction shaft rotatably connected to the top of the tank body parallel to the aeration pipe, a pulley one fixedly mounted on the traction shaft, a pulley two fixedly mounted at the end of the sleeve, the pulley one and pulley two being connected by a belt, a float fixedly mounted on one straight section of the belt, and an aeration hole on the aeration pipe, the air inlet end of the aeration pipe being connected to an air source.

[0008] Furthermore, the aeration holes are strip-shaped and parallel to the axis of the aeration pipe.

[0009] Furthermore, a tension spring is connected between the straight section of the belt and the pool wall.

[0010] This solution employs a water-float driven method. During liquid surface fluctuations, the belt connected to the float experiences changes in force, which in turn drives the pulley connected to the belt to rotate, i.e., the sleeve rotates. The rotation of the sleeve causes changes in the air outlet area on the aeration pipe, thereby continuously switching the air outlet direction and position, achieving air blowing over a larger area in different directions. The airflow acts on the lowest point of the pool bottom, causing the sediment accumulated at the lowest point to remix with the water, preventing the pool bottom from hardening. Simultaneously, this approach allows for the replacement of traditional small aeration holes with larger channel structures, avoiding clogging. Liquid surface fluctuations within the pool are inevitable due to the height difference between the inlet water and the liquid surface, causing impacts and fluctuations. Furthermore, the inlet and outlet water speeds cannot be perfectly synchronized, allowing the smaller diameter pulley to rotate a larger angle during small-amplitude belt traction.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 and Figure 2 As shown, the system includes a pool body 1 with a slope at the bottom. An aeration pipe 2 is rotatably connected to the lowest point of the pool bottom. A sleeve 3 is rotatably connected to the outside of the aeration pipe 2. The sleeve 3 has a spiral groove 4. A traction shaft 5 parallel to the aeration pipe 2 is rotatably connected to the top of the pool body 1. A pulley 6 is fixedly installed on the traction shaft 5. A pulley 7 is fixed to the end of the sleeve 3. The pulley 6 and the pulley 7 are connected by a belt 8. A float 9 is fixedly installed on one of the straight sections of the belt 8. The aeration pipe 2 has aeration holes 10. The air inlet end of the aeration pipe 2 is connected to an air source. The aeration holes 10 are strip-shaped and parallel to the axis of the aeration pipe 2.

[0016] A tension spring 11 is also connected between the middle of the straight section of the belt 8 and the pool wall. The tension of the tension spring 11 can be adjusted by its fixed position on the pool wall to ensure that the float 9 is below the liquid surface or in a semi-floating state during liquid surface fluctuations. In this way, when the liquid surface changes, the buoyancy of the float fluctuates and the belt 8 loses balance. The tension spring 11 and the float 9 can be on two different straight sections of the belt 8. The tension spring 11 applies a pre-tension force to the float 9 when it enters the water.

[0017] This scheme employs a water-float driven method. During the liquid surface fluctuation, the force on the belt 8 connected to the float 9 changes, thereby driving the pulley 7 connected to the belt 8 to rotate, i.e., the sleeve 3 rotates. The rotation of the sleeve 3 can drive the air outlet area on the aeration pipe 2 to change, thus continuously switching the air outlet direction and position of the aeration pipe 2, achieving air blowing over a larger area in different directions. The airflow acts on the lowest point of the pool bottom, causing the sediment accumulated at the lowest point to remix with the water, preventing the pool bottom from hardening. At the same time, this approach allows the traditional small aeration holes to be replaced with a larger trough structure, avoiding clogging. Liquid surface fluctuation within the pool 1 is inevitable because there is a height difference between the inlet water and the liquid surface, causing the impact on the water surface. In addition, the inlet and outlet water speeds cannot be completely consistent, allowing the smaller diameter pulley 7 to rotate a larger angle during the small-amplitude traction of the belt 8.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
