Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a ceramic polishing wastewater treatment device. Background Art

[0002] After ceramic products are formed, they need to be ground and polished to ensure that the surface of the ceramic products is smooth enough. Abrasives and coolants are used in the polishing process, and the tools and ceramic surfaces need to be rinsed and cleaned frequently. These processes will generate wastewater.

[0003] At present, when ceramic products are polished, circulating water is generally used to wash away the ceramic waste generated during polishing, and the waste is intercepted and separated by setting a filter element so that the water can be recycled. For example, the ceramic polishing wastewater treatment device disclosed in patent publication number CN213221287U, since the ceramic waste is usually small and suspended in the water, in order to improve the separation effect of the ceramic polishing wastewater, a flocculant feeding structure is usually also provided in the wastewater treatment device;

[0004] There are usually two working modes for flocculant feeding structure, one is to add flocculant to the wastewater tank at a fixed time and quantity, and the other is to continuously add flocculant to the wastewater in a continuous and quantitative manner. The effects of the two feeding methods are roughly the same. Both can make the suspended waste in the circulating water flocculate and precipitate by quantitatively adding flocculants to improve the separation effect. However, since the surface of ceramic products is relatively rough in the initial state during polishing, the amount of waste generated at this time is large, and as the polishing progresses, the amount of waste generated gradually decreases. The quantitative addition method is not only easy to cause the waste in the initial stage to be unable to fully flocculate and precipitate, affecting the separation effect of ceramic polishing wastewater, but also in the later stage of ceramic polishing, it is easy to cause excessive addition of flocculants and cause waste. At the same time, due to the impact force generated when the wastewater enters, it is easy to cause water disturbance, which will also have a certain impact on the separation of wastewater.

[0031] The adjustment component 138 includes an insulating hollow plate 36 fixedly installed on the top of the water inlet seat 4, and a resistance rod 37 and an electromagnetic push rod 38 are fixedly installed inside the insulating hollow plate 36.

[0032] The walls of the main water inlet chamber 5 and the backup water inlet chamber 6 are provided with a T-shaped liquid outlet hole 14, a second normally closed solenoid valve 16 is installed inside the hole connecting the T-shaped liquid outlet hole 14 and the backup water inlet chamber 6, a second normally open solenoid valve 15 is installed inside the hole connecting the T-shaped liquid outlet hole 14 and the backup water inlet chamber 6, a discharge hopper 17 is provided at the bottom of the sedimentation area 2, a flocculant storage tank 19 is plugged into the top of the wastewater tank 1, a protrusion 20 is fixedly installed at the bottom of the flocculant storage tank 19, and the inside of the protrusion 20 A discharge mechanism 21 is installed, and the discharge mechanism 21 includes a columnar cavity 211 opened inside the protrusion 20, and a motor drive assembly 212 is fixedly installed inside the columnar cavity 211, and the motor drive assembly 212 is drivingly connected to a discharge roller 213, and the outer wall of the discharge roller 213 is fixedly sleeved with a rubber sleeve 214, and the rubber sleeve 214 and the side wall of the discharge roller 213 are jointly provided with a plurality of groups of drop holes 215, and the bottom of the flocculant storage tank 19 is provided with a cylindrical cavity 211.

The motor drive assembly 212 is electrically connected to the resistance rod 37 and the conductive slip ring 40 through the controller 31.

[0033] A pump 22 connected to the clean water area 3 is fixedly installed on the outer wall of the wastewater tank 1, and the output end of the pump 22 is fixedly connected to a hollow column 23, and the end of the hollow column 23 is fixedly plugged with a drainage pipe 24, and the side wall of the hollow column 23 is fixedly plugged with a hood 26, and the top of the hood 26 is fixedly plugged with a circulation pipe 27, and the hood 26 is installed with a drainage detection mechanism 29 inside. The drainage detection mechanism 29 includes two second insulating slot boxes 291 fixedly installed on the inner wall of the hood 26, one of the second insulating slot boxes 291 is fixedly installed with a second LED lamp 292, and the other second insulating slot box 291 is fixedly installed with a second light sensing component 293, and the center point of the second LED lamp 292 and the second light sensing component 293 is at At the same height, the notches of the two second insulating slot boxes 291 are fixedly encapsulated with a second glass plate 294, the second LED lamp 292 and the second light sensing component 293 are electrically connected to the controller 31, the second light sensing component 293 is mainly composed of photosensitive material, when the light intensity irradiated to the second light sensing component 293 is small, the resistance of the second light sensing component 293 is large, and the drain pipe 24, the discharge hopper 17, and the circulation pipe 27 are all equipped with electric control valves. The controller 31 controls the on and off of the electric control valves in the drain pipe 24 and the discharge hopper 17, so that the wastewater and sediment in the wastewater tank 1 can be discharged. When the wastewater is recycled, the electric control valve in the circulation pipe 27 is kept open, and the electric control valves in the discharge hopper 17 and the drain pipe 24 are closed.

[0034] An air collection prompting mechanism 30 is fixedly installed on the top of the wastewater tank 1, and the air collection prompting mechanism 30 is electrically connected to the water inlet detection mechanism 13 and the drainage detection mechanism 29 respectively. The air collection prompting mechanism 30 includes a filter box 301 fixedly installed on the top of the wastewater tank 1, and an air pump 302 is fixedly installed on the top of the filter box 301, and the air outlet end of the air pump 302 is connected to the filter box 301, and an air pressure automatic switch 303 is fixedly installed on the inner bottom of the filter box 301, and an air outlet hole 304 is opened on the side wall of the filter box 301, and a third normally closed solenoid valve 305 is installed inside the air outlet hole 304, and a first sound and light alarm 306 and a second sound and light alarm 35 are fixedly installed on the top of the filter box 301. Within 40 seconds after the controller 31 starts a single polishing, the first light alarm 306 and the second sound and light alarm 35 are fixedly installed. The sensing component 135 is electrically connected to the third normally closed electromagnetic valve 305 through the controller 31 and the regulating component 138, and the third normally closed electromagnetic valve 305 is electrically connected to the resistor rod 37 and the conductive slip ring 40 through the controller 31. When the moving contact of the air pressure automatic switch 303 is closed, the air pressure automatic switch 303 is electrically connected to the second sound and light alarm 35 through the controller 31. In the initial 40 seconds of polishing, when the polishing sand disc for polishing ceramic products is less worn, the amount of waste generated by the polishing sand disc when polishing ceramic products is more. At this time, the light intensity projected to the first light sensing component 135 is smaller due to the obstruction of the waste, so the resistance of the first light sensing component 135 is larger. At this time, the current passed into the electromagnetic push rod 38 is smaller. At this time, the conductive slip ring 40, the resistor The current in the connection circuit between the rod 37 and the third normally closed solenoid valve 305 is relatively large, so the opening degree of the third normally closed solenoid valve 305 is also relatively large. Therefore, when the polishing sand disc is less worn, the gas passed into the filter box 301 can be discharged in time. On the contrary, if the polishing sand disc is more worn, then at the initial stage of polishing the ceramic product, there is less ceramic waste generated by polishing. At this time, the air passed into the filter box 301 cannot be discharged in time, so the automatic air pressure switch 303 can be closed, so that the second sound and light alarm 35 can be operated through the controller 31. The operation of the second sound and light alarm 35 indicates that the polishing sand disc used for polishing the ceramic product may be excessively worn. After 40 seconds after the controller 31 starts a single polishing, the second sound and light alarm 35 is turned on. The second photosensitive component 293 is electrically connected to the third normally closed solenoid valve 305 through the controller 31, and when the moving contact of the air pressure automatic switch 303 is closed, the air pressure automatic switch 303 is electrically connected to the first sound and light alarm 306 through the controller 31. If the water passing through the hood 26 is relatively turbid (indicating that there are more impurities in the circulating water and it can no longer meet the water requirements for ceramic polishing and rinsing), the light intensity projected to the second photosensitive component 293 is relatively small. At this time, the resistance of the second photosensitive component 293 is relatively large, so the current passed into the third normally closed solenoid valve 305 is relatively small. At this time, the air inside the filter box 301 cannot be discharged in time until the moving contact of the air pressure automatic switch 303 is closed, so that the first sound and light alarm 306 can be alarmed.It indicates that the circulating water needs to be replaced. Under the squeezing effect of the air pressure, the moving contact of the air pressure automatic switch 303 will close. After the air pressure returns to normal pressure, it can rebound and reset under the action of its own elastic element. This is an existing mature technology, so it will not be described here. Air is filled into the filter box 301 through the air pump 302 to increase the air pressure inside the filter box 301 to a certain value, and then the moving contact of the air pressure automatic switch 303 is closed to start the first sound and light alarm 306 or the second sound and light alarm 35 to alarm. The cumulative alarm method can avoid the traditional direct trigger alarm method. Avoid false alarms, such as in the initial 40 seconds of the polishing stage, it can prevent the occasional polishing sand disc from directly alarming when the amount of waste generated when polishing ceramic products is small, and after the 40 seconds of the polishing stage, the local turbidity in the circulating water directly alarms when passing through the machine cover 26, thereby improving the accuracy of the alarm. Among them, the third normally closed solenoid valve 305 is in a closed state when it is not powered on. As the current introduced increases, the electromagnetic force generated by itself becomes larger, and the degree of opening of the adsorption gate will also increase synchronously. This is an existing mature technology, so it will not be repeated here.

[0035] A stainless steel mesh 32 is fixedly installed inside the filter box 301, and the interior of the filter box 301 above the stainless steel mesh 32 is filled with a filter filler 33. A dust suction hose 34 is fixedly installed at the suction end of the air pump 302. The dust entering the filter box 301 can be intercepted and collected through the filter filler 33. During installation, the dust suction hose 34 is installed around the ceramic polishing position to absorb the dust that may be generated during polishing. The side wall of the filter box 301 is provided with a material replacement port sealing door for replacing the filter filler 33.

[0036] The operating principle of the present invention is now described as follows: connect the three-way pipe 9 to the drain outlet of the ceramic polishing and grinding device, connect the circulation pipe 27 to the water inlet of the ceramic polishing and grinding device, and then connect the controller 31 to the external power supply line;

[0037] When polishing ceramic products, the start switch of the controller 31 is pressed, and the controller 31 controls the machine pump 22 to work. The machine pump 22 can pump out the water in the clean water area 3, and transport the water to the water inlet of the ceramic polishing and grinding device through the hollow column 23, the machine cover 26 and the circulation pipe 27. The water sprayed through the water inlet can wash away the ceramic waste generated during polishing, and is discharged into the three-way pipe 9 through the drainage port of the ceramic polishing and grinding device;

[0038] At the beginning, the water discharged through the three-way pipe 9 will enter the main water inlet chamber 5. As the water inside the main water inlet chamber 5 increases, the piston plate 121 can be pushed to drive the pressure rod 122 to move downward until the pressure rod 122 presses the moving contact of the closed pressure switch 124. At this time, the controller 31 will receive the closing electrical signal of the pressure switch 124, and the controller 31 cooperates with the delayed power-off relay 137 to start the first normally open solenoid valve 10 and the first normally closed solenoid valve 11 inside the three-way pipe 9 and the second normally open solenoid valve 15 and the second normally closed solenoid valve 16 inside the T-shaped liquid outlet hole 14, and delay the power off for 15 seconds. At the same time, the controller 31 will start the first LED lamp 132 and turn on the first light sensing component 1 inside the main water inlet chamber 5. The connection circuit between the first LED lamp 132 and the electromagnetic push rod 35 is connected, and the connection circuit between the resistor rod 37 and the conductive slip ring 40 and the motor drive component 212 is connected at the same time. At this time, the water entering through the three-way pipe 9 will enter the inside of the standby water inlet chamber 6, and the water inside the main water inlet chamber 5 will be discharged into the drainage chamber 7 through the T-shaped liquid outlet hole 14, and the light generated by the first LED lamp 132 can be projected to the first light sensing component 135 in the main water inlet chamber 5 through the first glass plate 136 at the main water inlet chamber 5, and the ceramic waste in the wastewater will block the light irradiated into the main water inlet chamber 5 by the first LED lamp 132. Therefore, the light intensity projected to the first light sensing component 135 in the main water inlet chamber 5 increases with the ceramic waste in the water. As the amount of material increases, the resistance of the first light sensing component 135 increases synchronously due to the decrease in the intensity of light received. At this time, the current passed through the controller 31 into the electromagnetic push rod 38 becomes smaller synchronously. Therefore, the electromagnetic push rod 38 drives the conductive slip ring 40 to move a smaller distance through the insulating movable plate 39. At this time, the length of the resistor rod 37 connected to the connection circuit between the conductive slip ring 40 and the motor drive component 212 is shorter, so the current passed into the motor drive component 212 is larger. At this time, the motor drive component 212 drives the discharging roller 213 to rotate faster, so the granular flocculant entering the discharging pipe 217 through the discharging hole 216 and the drop hole 215 will also increase, and the granular flocculant entering the discharging pipe 217 will increase. The flocculant will also synchronously slide into the T-shaped liquid outlet 14 and mix with the wastewater, and finally enter the sedimentation area 2 through each water injection pipe 8. If there is less ceramic waste in the water in the main water inlet chamber 5, the water is relatively clear at this time, so the light intensity projected to the first light sensing component 135 in the main water inlet chamber 5 is relatively high at this time. At this time, the current passed into the electromagnetic push rod 38 is relatively large, so at this time, the length of the connection circuit between the resistor rod 37 connected to the conductive slip ring 40 and the motor drive component 212 is relatively long. At this time, the current passed into the motor drive component 212 becomes smaller, so the rotation speed of the discharge roller 213 slows down, and the amount of flocculant discharged into the T-shaped liquid outlet 14 will also decrease, ensuring the flocculation effect while reducing the waste of flocculant;

[0039] When the water is injected into the sedimentation area 2 through the water injection pipe 8, it is blocked by the water injection pipe 8 and will not cause excessive impact disturbance to the wastewater in the sedimentation area 2. Therefore, the impact on the sedimentation of the wastewater in the sedimentation area 2 is small. As the amount of water injected into the sedimentation area 2 by the water injection pipe 8 increases, the water in the sedimentation area 2 will gradually rise from the bottom, causing the clean water to overflow into the clean water area 3. Under the action of the flocculant, the ceramic waste will flocculate, and under the action of gravity, the flocculated ceramic waste will settle into the discharge hopper 17.

[0040] As the water inside the main water inlet chamber 5 is discharged, under the action of the spring 123, the piston plate 121 moves up and resets, and after the first normally open solenoid valve 10, the first normally closed solenoid valve 11, the second normally open solenoid valve 15 and the second normally closed solenoid valve 16 are powered off for 15 seconds, the water in the three-way pipe 9 will re-enter the main water inlet chamber 5, and the controller 31 will synchronously connect the connection circuit between the first light sensing component 135 and the motor drive component 212 in the standby water inlet chamber 6, and the water in the standby water inlet chamber 6 will also be discharged through the T-shaped liquid outlet 14. At the same time, the motor drive component 212 will also discharge the flocculant through the discharge roller 213 and mix it with the wastewater discharged from the standby water inlet chamber 6. As the amount of water entering the main water inlet chamber 5 increases, when the pressure switch 124 is triggered again, the main water inlet chamber 5 and the standby water inlet chamber 6 switch to drainage again;

[0041] When the controller 31 is started, the air pump 302 will be started synchronously, and the controller 31 will connect the connection circuit between the air pressure automatic switch 303 and the second sound and light alarm 35 within the initial 40 seconds when the ceramic product starts to be polished, and connect the connection circuit between the first light sensing component 135 and the electromagnetic push rod 38, and connect the connection circuit between the resistance rod 37 and the conductive slip ring 40 and the third normally closed electromagnetic valve 305. When the air pump 302 is working, the dust that may be generated at the ceramic polishing can be sucked into the filter box 301 through the dust suction hose 34, and the dust is intercepted by the filter filler 33. When the third normally closed electromagnetic valve 305 is energized, in the initial stage of polishing the ceramic product, when the polishing sand disc for polishing the ceramic product is less worn, the polishing sand disc generates a large amount of waste when polishing the ceramic product. At this time, the light intensity projected to the first light sensing component 135 is small due to the obstruction of the waste, so the resistance of the first light sensing component 135 is large. At this time, the current passed into the electromagnetic push rod 38 is small, so the third normally closed electromagnetic valve 305 is passed. The current in the connection circuit between the normally closed solenoid valve 305 and the conductive slip ring 40 and the resistor rod 37 is relatively large, so the opening degree of the third normally closed solenoid valve 305 is also relatively large. Therefore, when the polishing sand disc is less worn, the gas introduced into the filter box 301 can be discharged in time. If the polishing sand disc is more worn, the amount of waste generated by the polishing sand disc when polishing ceramic products is less. At this time, the corresponding current introduced into the third normally closed solenoid valve 305 is also relatively small, and the opening degree of the third normally closed solenoid valve 305 is also relatively small. Therefore, the air pressure inside the filter box 301 will gradually increase until the moving contact of the air pressure automatic switch 303 is closed under a certain air pressure, so that the second sound and light alarm 35 can be powered on to alarm. Under the action of the controller 31, the second sound and light alarm 35 will delay power off for 30 minutes. When the on-site operator hears the alarm information of the second sound and light alarm 35, it is necessary to immediately check the wear degree of the polishing sand disc and replace the severely worn polishing sand disc. At the same time, it is necessary to shut down the second sound and light alarm 35.

[0042] After the controller 31 is started, the second LED lamp 292 will be started synchronously, and when the third normally closed solenoid valve 305 is disconnected from the first light sensing component 135 circuit after 40 seconds, the controller 31 will synchronously connect the connection circuit between the third normally closed solenoid valve 305 and the second light sensing component 293, and switch the air pressure automatic switch 303 to be connected to the first sound and light alarm 306. The circulating water discharged through the circulation pipe 27 needs to pass through the hood 26. If the water passing through the hood 26 is relatively clear, the light intensity of the second LED lamp 292 irradiating the second light sensing component 293 is relatively large. At this time, the resistance of the second light sensing component 293 is relatively small, so the current passing into the third normally closed solenoid valve 305 is relatively large. , the third normally closed solenoid valve 305 is opened to a greater extent. If the water passing through the hood 26 is relatively turbid (indicating that there are more impurities in the circulating water and it can no longer meet the water requirements for ceramic polishing and rinsing), the light intensity projected to the second photosensitive component 293 is relatively small. At this time, the resistance of the second photosensitive component 293 is relatively large, so the current passed into the third normally closed solenoid valve 305 is relatively small. At this time, the air inside the filter box 301 cannot be discharged in time until the moving contact of the air pressure automatic switch 303 is closed under a certain air pressure, thereby enabling the first sound and light alarm 306 to alarm. At this time, personnel need to discharge the water in the wastewater tank 1 and the ceramic waste sediment inside the discharge hopper 17.
