Description
Technical Field

which is not described in detail herein, compared with the traditional direct triggering alarm mode, the false alarm phenomenon can be avoided, such as in the initial 40 seconds of the polishing stage, the false alarm phenomenon that the direct alarm appears under the condition that the sporadic polishing sand disc produces less waste material volume when polishing ceramic products can be prevented to and after the 40 seconds of polishing stage is finished, local turbidity in the circulating water is directly false alarm when passing through the hood 26, thereby can improve the accuracy of reporting to the police, wherein, third normally closed solenoid valve 305 is in the closed state when not circular telegram, along with the electric current increase of letting in, the electromagnetic force that its self produced also can become big simultaneously, the degree of adsorbing flashboard opening also becomes big, this is prior art that matures, so this is not repeated here.

The operation principle of the present invention will now be described by connecting the tee 9 to the water outlet of the ceramic polishing and grinding device, connecting the circulation pipe 27 to the water inlet of the ceramic polishing and grinding device, and then connecting the controller 31 to an external power supply line;
When the ceramic products are polished, the starting switch of the controller 31 is pressed, the controller 31 controls the pump 22 to work, the pump 22 can pump out water liquid in the clear water zone 3, the water liquid is conveyed to the water inlet of the ceramic polishing and grinding device through the hollow column 23, the hood 26 and the circulating pipe 27, and ceramic waste generated during polishing can be washed down through the water liquid sprayed from the water inlet and is discharged into the three-way pipe 9 through the water outlet of the ceramic polishing and grinding device;
At the beginning, the water discharged through the three-way pipe 9 can enter the main water inlet cavity 5, along with the increase of the water in the main water inlet cavity 5, the piston plate 121 can be pushed to drive the touch lever 122 to move downwards until the touch lever 122 presses the movable contact of the pressure switch 124 to be closed, at the moment, the controller 31 receives the closing electric signal of the pressure switch 124, the controller 31 is matched with the delay power-off relay 137 to start the first normally-open electromagnetic valve 10 and the first normally-closed electromagnetic valve 11 in the three-way pipe 9 and the second normally-open electromagnetic valve 15 and the second normally-closed electromagnetic valve 16 in the T-shaped liquid outlet hole 14, and delay power-off is carried out for 15 seconds, at the same time, the controller 31 can start the first LED lamp 132 and switch on the connecting loop between the first light sensing component 135 and the electromagnetic push rod 38 in the main water inlet cavity 5, and switch on the connecting loop between the resistance rod 37 and the conductive slip ring 40 and the motor driving component 212 at the moment, the water liquid entering through the three-way pipe 9 enters the water preparing cavity 6, the water liquid in the main water inlet cavity 5 is discharged into the water draining cavity 7 through the T-shaped liquid outlet hole 14, the light generated by the operation of the first LED lamp 132 can be projected to the first light sensing component 135 in the main water inlet cavity 5 through the first glass plate 136 at the position of the main water inlet cavity 5, the ceramic waste in the wastewater can shield the light of the first LED lamp 132 which irradiates into the main water inlet cavity 5, so that the light intensity of the first light sensing component 135 projected into the main water inlet cavity 5 is reduced along with the increase of the ceramic waste in the water liquid, the resistance of the first light sensing component 135 is synchronously increased due to the decrease of the received light intensity, at the moment, the current which is introduced into the electromagnetic push rod 38 through the controller 31 synchronously decreases, therefore, the electromagnetic push rod 38 drives the moving distance of the conductive slip ring 40 to be smaller through the insulating movable plate 39, at this time, the length of the resistor rod 37 connected into the connecting loop of the conductive slip ring 40 and the motor driving component 212 is shorter, so that the current introduced into the interior of the motor driving component 212 is larger, at this time, the rotating speed of the motor driving component 212 driving the discharge roller 213 is higher, so that the length of the resistor rod 37 connected into the connecting loop of the conductive slip ring 40 and the motor driving component 212 is longer, at this time, the current introduced into the interior of the motor driving component 212 is smaller, the rotating speed of the discharge roller 213 is slower, the flocculating agent introduced into the interior of the discharge pipe 217 is synchronously slid into the T-shaped liquid outlet 14 to be mixed with the wastewater, and finally, the flocculating agent enters the sedimentation zone 2 through each water injection pipe 8, if the ceramic waste in the water in the main water inlet cavity 5 is smaller, at this time, the light intensity of the first light sensing component 135 projected into the main water inlet cavity 5 is relatively clear, at this time, the current introduced into the interior of the electromagnetic push rod 38 is larger, at this time, so that the length of the resistor rod 37 connected into the connecting loop of the conductive slip ring 40 and the motor driving component 212 is longer, at this time, the current introduced into the interior of the motor driving component 212 is smaller, so that the rotating speed of the discharge roller 213 is slower, and the flocculating agent is discharged into the T-shaped liquid outlet 14, the flocculating agent is less, and the flocculating agent is discharged into the flocculating effect is ensured, and the flocculating effect is reduced;
when water liquid is injected into the sedimentation zone 2 through the water injection pipe 8, the water liquid is blocked by the water injection pipe 8, and the water liquid cannot cause excessive impact disturbance on the wastewater in the sedimentation zone 2, so that the influence on the wastewater sedimentation in the sedimentation zone 2 is small, the water liquid in the sedimentation zone 2 gradually rises from the lower side along with the increase of the water quantity injected into the sedimentation zone 2 by the water injection pipe 8, so that clear water overflows into the clear water zone 3, and under the action of a flocculating agent, the ceramic waste can generate flocculation phenomenon, and under the action of gravity, the flocculated ceramic waste is precipitated into the discharge hopper 17;
As the water in the main water inlet cavity 5 is discharged, the piston plate 121 moves upwards to reset under the action of the spring 123, and after the first normally open electromagnetic valve 10, the first normally closed electromagnetic valve 11, the second normally open electromagnetic valve 15 and the second normally closed electromagnetic valve 16 are delayed and powered off for 15 seconds, the water in the three-way pipe 9 can reenter the main water inlet cavity 5, the controller 31 can synchronously switch on a connecting loop between the first light sensing component 135 and the motor driving component 212 in the standby water inlet cavity 6, the water in the standby water inlet cavity 6 can also be discharged through the T-shaped liquid outlet hole 14, meanwhile, the motor driving component 212 can also discharge the flocculating agent through the discharge roller 213 and mix the wastewater discharged in the standby water inlet cavity 6, and when the pressure switch 124 is triggered again, the main water inlet cavity 5 and the standby water inlet cavity 6 are switched again for water discharge;
When the controller 31 is started, the air pump 302 is synchronously started, the controller 31 can connect the connecting loop between the ventilation pressure automatic switch 303 and the second audible and visual alarm 35 and the connecting loop between the first light sensing component 135 and the electromagnetic push rod 38 in the initial 40 seconds when the ceramic product starts polishing, and simultaneously connect the connecting loop between the resistance rod 37 and the conductive slip ring 40 and the third normally closed electromagnetic valve 305, when the air pump 302 works, dust possibly generated at the ceramic polishing position can be sucked into the filter box 301 through the dust suction hose 34 and is trapped by the filter packing 33, when the third normally closed electromagnetic valve 305 is electrified, in the initial stage of polishing the ceramic product, when the abrasion of a polishing sand disc for polishing the ceramic product is smaller, the amount of waste generated when the polishing sand disc polishes the ceramic product is more, and at the moment, the waste is blocked, the light intensity projected to the first light sensing component 135 is smaller, the resistance of the first light sensing component 135 is larger, at this time, the current flowing into the electromagnetic push rod 38 is smaller, the current flowing into the connecting loop between the third normally closed electromagnetic valve 305 and the conductive slip ring 40 and the resistance rod 37 is larger, so that the opening degree of the third normally closed electromagnetic valve 305 is larger, therefore, when the abrasion of the polishing sand disc is smaller, the gas flowing into the filter box 301 can be timely discharged, if the abrasion of the polishing sand disc is larger, the waste generated when the polishing sand disc polishes ceramic products is smaller, at this time, the corresponding current flowing into the third normally closed electromagnetic valve 305 is smaller, the opening degree of the third normally closed electromagnetic valve 305 is smaller, the air pressure in the filter box 301 is gradually increased until the movable contact of the air pressure automatic switch 303 is closed under the action of a certain air pressure, so that the second light alarm 35 can be electrified and alarm, the second audible and visual annunciator 35 is powered off after being delayed for 30 minutes under the action of the controller 31, when an on-site operator hears the alarm information of the second audible and visual annunciator 35, the wearing degree of the polishing disc needs to be checked immediately, the polishing disc with serious wearing is replaced, and meanwhile, the second audible and visual annunciator 35 needs to be turned off;
The controller 31 starts the second LED lamp 292 synchronously after starting, and when the third normally closed electromagnetic valve 305 is disconnected from the loop of the first light sensing component 135 after 40 seconds, the controller 31 synchronously switches on the connecting loop between the third normally closed electromagnetic valve 305 and the second light sensing component 293, and makes the air pressure automatic switch 303 switch on with the first audible and visual annunciator 306, and the circulating water liquid discharged through the circulating pipe 27 needs to pass through the hood 26, if the water liquid passing through the hood 26 is clear, the light intensity of the second LED lamp 292 irradiated to the second light sensing component 293 is larger, at this time, the resistance of the second light sensing component 293 is smaller, so the current introduced into the third normally closed electromagnetic valve 305 is larger, at this time, the opening degree of the third normally closed electromagnetic valve 305 is larger, and if the water liquid passing through the hood 26 is more impurities (indicating that the circulating water liquid is more, the water liquid requirement for ceramic polishing cannot be met), the resistance of the second light sensing component 293 is smaller, the current of the second light sensing component 293 is larger, at this time, the current introduced into the third normally closed electromagnetic valve 293 is smaller, the air pressure is smaller, and the air pressure alarm 301 is discharged from the inside the filter box is required to be closed, and the inside the air tank is no more, and the air pressure alarm device is required to be discharged from the inside the filter box, and the filter box is no more than the air, and the filter box is required to be evacuated by the air, and the filter tank is no under the condition conditions, and the condition has been activated.
