Technical Field

[0001] The utility model relates to the technical field of glasses processing, in particular to a lens grinding device for glasses production. Background Art

[0002] As we all know, glasses are composed of lenses and frames, and are used to improve vision, protect eyes or for decorative purposes. In the production process of glasses, there are many steps, among which the lenses need to be polished. In the process of lens polishing, in order to avoid overheating of the polishing area or accumulation of powder generated by polishing, it is generally flushed after polishing. Although flushing after polishing is a common process in polishing, the sewage generated after flushing becomes a product that needs to be treated, thus extending the corresponding sewage filtration treatment mechanism.

[0003] At present, there are many sewage filtration and treatment mechanisms for lens grinding, such as a kind of optical glass lens grinding wastewater treatment device disclosed in patent CN202122838093.3, which includes a filter box and an auxiliary mechanism, a filter chamber is provided at the top of the filter box, a rectangular frame is provided inside the filter chamber, a filter screen is provided inside the rectangular frame, and the auxiliary mechanism is composed of a connecting rod, a movable rod, a connecting block and an extrusion block, the connecting rod is fixedly connected to the top of the rectangular frame, a first movable hole is provided at the top of the connecting rod, a second movable hole is provided at the top of the rectangular frame, the connecting block is fixedly connected to the bottom of the movable rod, and the extrusion block is fixedly connected to the top of the connecting block. In principle, it mainly utilizes the setting of the movable rod, the connecting block and the extrusion block, and the movable rod moves up and down, so that the upward movement of the connecting block will drive the extrusion block to rise, so that the extrusion block hits the bottom of the filter screen, so that the filter screen vibrates, and the glass residue on the surface of the filter screen is shaken up, thereby avoiding the glass residue from clogging the filter screen and improving the filtering efficiency of the filter screen. Although this device can prevent filter clogging and improve the filtering efficiency of the filter, it mainly only targets the oscillation of the filter, and is not ideal for sewage recycling and waste collection, and needs to be improved.

[0020] like Figures 1 to 3As shown, the present embodiment provides a lens grinding device for eyeglass production, comprising a case 1 and a grinder 2 installed on the case 1 and used for grinding lenses. The grinder 2 is a conventional grinding mechanism, so this embodiment will not be described in detail. The case 1 is provided with a discharge funnel 3 directly below the grinder 2. The case 1 is provided with a filter chamber and an evaporation chamber inside. A filter box 4 is installed in the filter chamber. The discharge funnel 3 is connected to the inner cavity of the filter box 4 through a conducting pipe 5. The filter box 4 has a plurality of inner cavities. A filter basket 6 is placed, and a cavity is formed between the bottom and side surfaces of the filter basket 6 and the inner wall of the filter box 4. A vibrator 7 is installed at the bottom of the filter box 4. An evaporation disk 8 made of a heat-conducting material and a frame 9 for accommodating the evaporation disk 8 are provided in the evaporation chamber. A heating element 10 for conducting heat to the evaporation disk 8 is provided on the frame 9. An air inlet valve 11 and an exhaust fan 12 are provided in the evaporation chamber. At the same time, the mesh size of the filter basket 6 is 0.2 microns to 0.5 microns.

[0021] Among them, the chassis 1 is also provided with a first water pump 13, a second water pump 14, a drain pipe 15 for connecting to an external water source and a main unit (not shown in the figure) for controlling the overall orderly operation. The pipe mouth of the drain pipe 15 is placed in the filter box 4, the water inlet pipe of the first water pump 13 is placed in the compartment, the water outlet pipe of the first water pump 13 is provided with a nozzle 16 and is placed at the grinding station of the grinder 2, the water inlet pipe of the second water pump 14 is placed in the filter basket 6, the water outlet pipe of the second water pump 14 is placed in the evaporation tray 8, and the first water pump 13, the second water pump 14 and the drain pipe 15 are all provided with a solenoid valve 17 for controlling the conduction of the pipeline.

[0022] This embodiment mainly relies on the filter chamber and the evaporation chamber to treat the wastewater generated by lens grinding. In particular, the vibrator 7 and the filter mesh plate 6 can filter the wastewater, and the filtered water can be used for grinding again, while the turbid water containing filter residues is sent to the evaporation plate 8, and the filter residues are filtered out by evaporation. On the one hand, the accumulation of filter residues on the filter mesh plate 6 can be avoided, and on the other hand, the filter mesh plate 6 does not need to be cleaned, and the removal of the filter residues is convenient.

[0023] During specific operation, the clean water is discharged into the filter box 4 through the drain pipe 15. When the water reaches a certain amount, the electromagnetic valve 17 at the drain pipe 15 will stop discharging. When the grinder 2 grinds the lens, the first water pump 13 will guide the water in the compartment to the grinding station of the grinder 2 to meet the grinding needs. The water used by the grinder 2 will fall into the discharge funnel 3, and then this part of the water will be sent to the filter box 4 through the conducting pipe 5. The water entering the filter box 4 will be actively filtered through the filter screen 6, and the filter residue will accumulate on the filter screen 6. When a lot of filter residue accumulates, it will affect the filtering efficiency. At this time, the vibrator 7 can be used to generate vibrations to suspend the filter residue accumulated on the filter screen 6, so that the filter screen 6 can be filtered smoothly again. After the filter residue is suspended, the second water pump 14 will suck this part of the filter residue and water into the evaporation disk 8. After a certain amount of suction, the extraction is stopped, and then the heating element 10 is heated to evaporate the water in the evaporation disk 8, leaving only the filter residue in the evaporation disk 8. At the same time, the exhaust fan 12 also works at this time to discharge water vapor to the outside, thereby completing the separation of the filter residue. According to specific needs, multiple repeated evaporation operations can be performed to meet the separation of the filter residue from the filter box 4. When it is necessary to remove the filter residue, the frame 9 and the evaporation disk 8 can be directly taken out together, and then the filter residue in the evaporation disk 8 can be cleaned up.

[0024] Furthermore, in order to avoid grinding errors or operating errors in the grinder 2, which may cause large lens fragments to fall into the filter box 4, a filter screen 18 is provided at the upper port of the conducting tube 5 of this embodiment. The mesh size of the filter screen 18 is 1mm-1.5mm. In order to further play a filtering role, a filter screen 18 is provided at the pipe mouth of the water inlet pipe of the first water pump 13 of this embodiment.

[0025] Furthermore, in order to prevent dust from escaping from the exhaust fan 12 after evaporation, the evaporation chamber of this embodiment is provided with a dust filter plate 19 at the exhaust fan 12, so that even if dust floats inside, it can be filtered.

[0026] Furthermore, in order to increase the filtering area, the dust filtering plate 19 of this embodiment is wavy in shape.

[0027] Furthermore, for water level monitoring of the filter box 4, a first water level sensor 20 is provided at the top of the filter basket 6 in the filter box 4, and a second water level sensor 21 is provided at the compartment of the filter box 4 and at the bottom of the filter basket 6. The detection of the first water level sensor 20 prevents the water level from being too high, while the detection of the second water level sensor 21 prevents the water level from being too low, thereby preventing dry pumping. When the second water level sensor 21 is triggered, the corresponding water needs to be added.

[0028] Furthermore, in order to facilitate the removal of the frame 9, a roller 22 is provided at the bottom of the frame 9 of this embodiment, and door panels 23 are provided at the evaporation chamber and the filter chamber of the chassis 1.

[0029] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
