Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a ceramic slurry filtering device. Background Art

[0002] In the prior art, when the ceramic slurry needs to be filtered, compressed air is used to pressurize the ceramic slurry holding steel pot, so that the ceramic slurry is transferred to another steel pot through a filter element under the pressure of air pressure, so as to filter out foreign matters such as impurities in the ceramic slurry. However, the following problems exist during use:

[0003] Question 1: Compressed air is pressurized to 0.4-0.6Mpa, which poses a safety hazard. There have been cases where the steel pot was in a stationary state and the air pressure inside the steel pot was unstable, causing the steel pot lid to blow off;

[0004] Question 2: When the filtration of ceramic slurry is completed, if the air pressure and the valve at the bottom of the steel pot are not closed in time, the compressed air will continue to blow towards the ceramic slurry. During the blowing, the residual ceramic slurry in the pipeline will be blown dry and enter the ceramic slurry again, causing ceramic powder to agglomerate on the surface of the ceramic diaphragm produced by cast film.

[0029] Example:

[0030] Reference Figure 1-Figure 4 A ceramic slurry filtering device includes a device box 1, and also includes: a liquid inlet pipe 2 and a liquid outlet pipe 3, which are respectively fixedly connected to the two sides of the device box 1, wherein a gear pump 4 is fixedly installed on the device box 1, and the output end of the gear pump 4 is fixedly connected to the input end of the liquid inlet pipe 2; a filter component is arranged in the device box 1, and the filter component is used to filter the slurry discharged by the gear pump 4;

[0031] When in use, connect the input end of the gear pump 4 to the ceramic slurry holding steel pot, and then start the gear pump 4. The gear pump 4 can extract the ceramic slurry from the holding steel pot, and then discharge it into the device box 1 through the liquid inlet pipe 2, and finally discharge it into another steel pot from the liquid outlet pipe 3 on the device box 1. When the ceramic slurry passes through the device box 1, the filtering component can filter the ceramic slurry. During the entire filtration process, the gear pump 4 is used instead of compressed air to filter the ceramic slurry, which can effectively reduce the safety hazards caused by high pressure, and effectively avoid the agglomeration of ceramic powder caused by no one closing the valve and air pressure when the ceramic slurry filtration is completed.

[0032] The filter component includes a slider 5 slidably mounted in the device box 1, a first filter element 7 and a second filter element 8 are fixedly mounted on the slider 5, wherein two ends of the second filter element 8 face the liquid inlet pipe 2 and the liquid outlet pipe 3 respectively, a telescopic device 6 is fixedly mounted on the outer wall of the device box 1, and the telescopic end of the telescopic device 6 is fixedly connected to the slider 5, and the telescopic device 6 is an electric telescopic rod;

[0033] When the ceramic slurry passes through the device box 1, the second filter element 8 can filter the ceramic slurry. When the second filter element 8 needs to be replaced, the slider 5 is driven by the telescopic device 6 to slide linearly in the device box 1, so that the slider 5 drives the second filter element 8 not to be aligned with the liquid inlet pipe 2 and the liquid outlet pipe 3, but to be aligned with the second backwash pipe 12 and the second sewage pipe 11, and the first filter element 7 is aligned with the liquid inlet pipe 2 and the liquid outlet pipe 3, so that the second filter element 8 and the first filter element 7 can be quickly replaced, thereby facilitating the use of the filtering device.

[0034] The outer wall of one side of the device box 1 is fixedly connected with the first backwash pipe 10 and the second backwash pipe 12, and the outer wall of the other side of the device box 1 is fixedly connected with the first sewage pipe 9 and the second sewage pipe 11, and the two ends of the first filter element 7 are respectively facing the first backwash pipe 10 and the first sewage pipe 9; a liquid storage box 13 for storing cleaning liquid is fixedly installed on the top of the device box 1, and a liquid filling port is provided on the top of the liquid storage box 13, and a sealing cover 22 is detachably installed on the liquid filling port, and the ends of the first backwash pipe 10 and the second backwash pipe 12 are extended to the inner bottom of the liquid storage box 13, and solenoid valves 14 are fixedly installed in the first backwash pipe 10 and the second backwash pipe 12;

[0035] After the replacement is completed, the solenoid valve 14 on the second backflush pipe 12 is started. At this time, the cleaning liquid in the liquid storage box 13 will flow into the second filter element 8 through the second backflush pipe 12, and then be discharged from the second sewage pipe 11. When the cleaning liquid passes through the second filter element 8, the second filter element 8 can be backwashed, thereby automatically completing the flushing work of the second filter element 8. When the first filter element 7 needs to be replaced, the solenoid valve 14 in the first backflush pipe 10 is started to complete the backwashing work of the first filter element 7. As a result, the first filter element 7 and the second filter element 8 can be automatically flushed, which is more convenient to use.

[0036] A telescopic airbag 15 is fixedly installed between the slider 5 and the inner walls of both sides of the device box 1. An air intake pipe 17 and an air exhaust pipe 16 are fixedly connected to the two telescopic airbags 15. A one-way valve is fixedly installed in the air intake pipe 17 and the air exhaust pipe 16. The end of the air exhaust pipe 16 extends to the inner top of the liquid storage box 13.

[0037] When the slider 5 slides in the device box 1, the slider 5 will compress one of the telescopic airbags 15 and stretch the other telescopic airbag 15. When the telescopic airbag 15 is compressed, it will blow air to the liquid storage box 13 through the exhaust pipe 16, thereby increasing the air pressure in the liquid storage box 13, so that the cleaning liquid can more efficiently rinse the first filter element 7 and the second filter element 8. When the telescopic airbag 15 is stretched, the telescopic airbag 15 will inhale air through the intake pipe 17.

[0038] Two push rods 18 are fixedly connected to the inner wall of the device box 1, and start buttons 19 are fixedly installed on the two push rods 18. The two start buttons 19 control the two solenoid valves 14 respectively. After the replacement is completed, the slider 5 presses against the start button 19 on one side, and the start button 19 automatically starts the solenoid valve 14 on the second recoil tube 12. Conversely, when the slider 5 is reset, it will press against the start button 19 on the other side, and the start button 19 will start the solenoid valve 14 in the first recoil tube 10, thereby automatically completing the start work of the solenoid valve 14. In order to automatically complete the closing work, the start button 19 can use a delay switch with a delayed closing function.

[0039] The bottom of the device box 1 is fixedly connected with a collecting box 20, the ends of the first sewage pipe 9 and the second sewage pipe 11 are extended into the collecting box 20, the bottom of the collecting box 20 is provided with a sewage outlet, the sewage outlet is detachably provided with a sewage cover 21, and the top of the collecting box 20 is provided with a vent pipe;

[0040] The collecting box 20 can effectively collect sewage discharged from the first sewage pipe 9 and the second sewage pipe 11 to prevent the sewage from polluting the surrounding environment, and the vent pipe can enable the collecting box 20 to be vented in time.

[0041] A suspension bracket 23 is fixedly connected to the bottom of the collection box 20. The suspension bracket 23 can lift the collection box 20 off the ground, thereby facilitating the discharge of sewage from the sewage outlet.

[0042] When the ceramic slurry filtering device is used, the input end of the gear pump 4 is connected to the ceramic slurry holding steel pot, and then the gear pump 4 is started. The gear pump 4 can extract the ceramic slurry from the holding steel pot, and then discharge it into the device box 1 through the liquid inlet pipe 2, and finally discharge it into another steel pot from the liquid outlet pipe 3 on the device box 1. When the ceramic slurry passes through the device box 1, the second filter element 8 can filter the ceramic slurry. During the whole filtering process, the gear pump 4 is used instead of compressed air to filter the ceramic slurry, which can effectively reduce the safety hazards caused by high pressure, and effectively avoid the agglomeration of ceramic powder caused by no one closing the valve and air pressure when the ceramic slurry filtering is completed;

[0043] When the second filter element 8 needs to be replaced, the sliding block 5 is driven to slide linearly in the device box 1 by the telescopic device 6, so that the sliding block 5 drives the second filter element 8 to align with the second backwash pipe 12 and the second sewage pipe 11 instead of the liquid inlet pipe 2 and the liquid outlet pipe 3, and the first filter element 7 is aligned with the liquid inlet pipe 2 and the liquid outlet pipe 3, so that the second filter element 8 and the first filter element 7 can be quickly replaced, thereby facilitating the use of the filtering device;

[0044] After the replacement is completed, the slider 5 is pressed against the start button 19 on one side, and the start button 19 will start the solenoid valve 14 on the second backwash pipe 12. At this time, the cleaning liquid in the liquid storage box 13 will flow into the second filter element 8 through the second backwash pipe 12, and then be discharged from the second sewage pipe 11. When the cleaning liquid passes through the second filter element 8, the second filter element 8 can be backwashed, thereby automatically completing the flushing work of the second filter element 8. When the first filter element 7 needs to be replaced, the telescopic device 6 drives the slider 5 to reset, so that the second filter element 8 can be put into use. At this time, the solenoid valve 14 in the first backwash pipe 10 will be opened by another start button 19, thereby completing the backwashing work of the first filter element 7, so that the first filter element 7 and the second filter element 8 can be automatically flushed, which is more convenient to use.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
