[0040] Furthermore, in order to prevent leakage of wastewater during filtration, sealing rubber rings are provided at the connections between the hollow tube 1 2 , the hollow tube 2 3 and the outer tube 4 .

[0041] Furthermore, in order to prevent waste water from entering the outer tube 4 from the hollow tube 2 3 , a sealing gasket is provided at the joint between the connecting block 1 7 and the hollow tube 2 3 .

[0042] A handle 6001 is provided on the connecting frame 6 .

[0043] The working steps of this embodiment are:

[0044] The following rotations are from front to back, from top to bottom, and from right to left.

[0045] The first step is to place the easily replaceable chemical filter device at the required position when in use;

[0046] In the second step, the operator connects an external power supply to all components that require electric drive, connects an external drainage pipe to the drain outlet 2001, connects an external wastewater pipe to the two water inlets 3001, and connects an external hot air blower to the circular tube 1 202. When working, the two electric valves 19 are controlled to open to connect the hollow tube 1 2 with the two hollow tubes 2 3, and then the wastewater in the wastewater pipe is controlled to be transported to the two hollow tubes 2 3 through the two water inlets 3001. After the wastewater enters the two hollow tubes 2 3, it will be filtered by the two cylindrical ceramic filter elements 8 to remove the pollutants in the wastewater, and the filtered wastewater will gather in the middle of the cylindrical ceramic filter element 8, and then the filtered wastewater will pass through the electric valve 19 into the hollow tube 2, and then be transported from the drain outlet 2001 of the hollow tube 2 to the drainage pipe to achieve filtration of the wastewater.

[0047] The third step is that since there is wastewater, tiny particles and dissolved substances on the old ceramic filter element 8, it is difficult for the operator to grab the old ceramic filter element 8, which makes it difficult to remove the old ceramic filter element 8, and the wastewater contains corrosive substances. When removing the old ceramic filter element 8, once the wastewater comes into contact with the skin, it will cause serious damage to the skin. Therefore, when the operator needs to replace the old ceramic filter element 8, taking the ceramic filter element 8 on the left as an example, the electric valve 9 on the left side of the hollow tube 2 is controlled to be closed to cut off the wastewater entering the hollow tube 2, and then the water inlet 3001 of the left hollow tube 2 3 is controlled to stop conveying wastewater and discharge the remaining wastewater in the left hollow tube 2 3. Then the operator grabs the handle 5001 to disassemble the sealing plate 5 of the left outer tube 4, and then grabs the handle 6001 of the connecting frame 6 to drive the connecting block 7 and the ceramic filter element 8 to move to the left together, and the connecting block 7, the old ceramic filter element 8 and the clamping assembly are taken out from the hollow tube 2 3 and the outer tube 4;

[0048] It should be noted that the connecting frame 6 is located inside the outer tube 4, and a sealing gasket is provided at the joint between the connecting block 1 7 and the hollow tube 2 3 to prevent the wastewater from entering the outer tube 4 during the wastewater filtration and causing the wastewater to contaminate the connecting frame 6;

[0049] When the old ceramic filter element 8 is manually taken out and placed vertically on the ground, the operator pushes the round block 105 and the four wedge blocks 106 to move toward the four wedge blocks 103, and the spring 104 is forced to compress. After the wedge block 106 contacts the wedge block 103, the wedge block 106 pushes the four wedge blocks 103 and the corresponding pressure block 102 to move in the groove 7001 toward the center of the connecting block 7. All the springs 101 are automatically compressed so that the pressure block 102 is no longer in contact with the old ceramic filter element 8. Then the operator takes the connecting frame 6, the connecting block 17 and the clamping assembly out of the old ceramic filter element 8, and then inserts the connecting rod 107, the cross 108 and the arc block 109 into the new ceramic filter element 8. 108 and arc block 109 correct the position of connecting block 7, so as to manually clamp the new ceramic filter element 8 on connecting block 7, then loosen round block 105, let spring 2 104 automatically drive four wedge blocks 2 106 to reset, no longer restricting pressing block 102 and wedge block 103, all springs 101 automatically reset, clamp the new ceramic filter element 8, then insert connecting frame 6, connecting block 17, new ceramic filter element 8 and clamping assembly into hollow tube 2 3 and outer tube 4 together, let the new ceramic filter element 8 be clamped on hollow tube 2, reinstall sealing plate 5 on outer tube 4, then control electric valve 19 to open, water inlet 3001 transports wastewater into hollow tube 2 3 again, and let the new ceramic filter element 8 continue to filter the wastewater;

[0050] In this way, when replacing the old ceramic filter element 8, the handle 6001 can be directly grasped to drive the connected parts to move and take out the old ceramic filter element 8. This not only makes it easy for the operator to take out the old ceramic filter element 8, but also prevents the waste water remaining on the old ceramic filter element 8 from contacting the human skin and causing damage to the skin. By pushing the round block 105, the connecting block 7 can be quickly separated from the old ceramic filter element 8, making it easy to replace the new ceramic filter element 8.

[0055] It also includes a transmission component, which is connected to the base 1; the transmission component includes a storage tank 301, a round tube 2 302, a curved tube 1 303, a pump 304, a connecting tube 1 305, a connecting tube 2 306, an electric valve 2 307, a curved tube 2 308 and an electric valve 3 309; the base 1 is fixedly connected to the storage tank 301; the upper part of the storage tank 301 is connected to two round tubes 2 302; the two round tubes 2 302 are each connected to a hollow tube 2 3; the two sides of the storage tank 301 are each connected to a curved tube 1 303; the two curved tubes 1 303 are each connected to a hollow tube 2 3; An outer tube 4 is connected; a pump 304 is bolted to the rear of the base 1; a connecting pipe 1 305 is connected to the input end of the pump 304, and the connecting pipe 1 305 is connected to the storage tank 301; a connecting pipe 2 306 is connected to the output end of the pump 304; an electric valve 2 307 is provided on the connecting pipe 2 306, and the electric valve 2 307 is a three-way valve; a bend pipe 2 308 is connected to each of the two ends of the electric valve 2 307; the two bend pipes 2 308 are each connected to a hollow tube 2 3; an electric valve 3 309 is provided in each circular tube 2 302.

[0056] The working principle of this embodiment is:

[0057] In step 3 of embodiment 1: since a small amount of acidic and alkaline waste water remains on the ceramic filter element 8, when the ceramic filter element 8 is detached from the outer tube 4, the residual acidic and alkaline waste water will fall to the ground. At the same time, the acidic and alkaline waste water remaining on the ceramic filter element 8 will also emit irritating waste gas, causing the external environment to be polluted by the acidic and alkaline waste water and irritating waste gas. Therefore, when it is necessary to replace the used ceramic filter element 8, taking the ceramic filter element 8 on the left as an example, the electric valve 9 on the left side of the hollow tube 2 is controlled to be closed to cut off the waste water entering the hollow tube 2. Then, the water inlet 3001 of the left hollow tube 2 3 is controlled to stop conveying wastewater. Before taking out the left ceramic filter element 8, the electric valve 3 309 in the left circular tube 2 302 is controlled to open, so that the wastewater in the left hollow tube 2 3 flows along the left circular tube 2 302 to the storage tank 301. After the wastewater in the left circular tube 2 302 is discharged, the operator grabs the handle 5001 to remove the sealing plate 5 of the left outer tube 4, and then grabs the connecting frame 6 to drive the connecting block 1 7 and the ceramic filter element 8 to move to the left together, so as to take out the left ceramic filter element 8;

[0058] During the process of taking out the ceramic filter element 8, the external hot air blower is controlled to start, and hot air is transported into the annular tube 201 through the circular tube 1 202. The hot air is ejected from several nozzles 203 of the annular tube 201, and the moving ceramic filter element 8 is blown by the continuously ejected hot air, so that the waste water remaining on the outer ring surface of the ceramic filter element 8 is blown to the right, and the remaining waste water is splashed into the outer tube 4. At the same time, the outer ring surface of the ceramic filter element 8 is dried by the hot air, and the waste water splashed into the outer tube 4 will gradually gather at the lower part of the outer tube 4, and then flow from the bend pipe 1 303 to the storage tank 301. At this time, since the waste water remaining on the ceramic filter element 8 is removed, the ceramic filter element 8 will not emit irritating waste gas. This can not only prevent the waste water from falling into the outside and polluting the environment, but also prevent artificial inhalation of irritating waste gas and endanger the health of the artificial.

[0059] At the same time, in the process of removing the waste water and waste gas remaining on the ceramic filter element 8, the waste gas will leak from the gap between the outer tube 4 and the ceramic filter element 8. Therefore, when the operator grabs the handle 6001 and prepares to move, the telescopic part of the electric push rod 206 is controlled to push out, driving the connecting block 207 and the end of the elastic rope 205 to move upward together, so that the elastic rope 205 shrinks on the elastic cloth 204, and the elastic cloth 204 is driven by the elastic rope 205 to be sleeved on the connecting frame 6, and then the operator brings the connecting frame 6, the connecting block 1 7 and the ceramic filter element 8 to move upward. During the process of transferring the elastic cloth 204 from the connecting frame 6 to the connecting block 7, the elastic rope 205 will be forced to stretch and the elastic cloth 204 will shrink, so that the elastic cloth 204 will always be on the connecting block 7. Then, during the process of transferring from the connecting block 7 to the ceramic filter element 8, the elastic rope 205 will automatically shrink, forcing the elastic cloth 204 to expand inward, so that the elastic cloth 204 will always be on the ceramic filter element 8, thereby blocking the gap between the outer tube 4 and the ceramic filter element 8 and preventing the continuously blown airflow from leaking from the gap between the outer tube 4 and the ceramic filter element 8.

[0060] After the operator installs the new ceramic filter element 8 back into the hollow tube 23, the pump 304 is controlled to be turned on, and the wastewater in the storage tank 301 is pumped into the pump 304 through the connecting pipe 1 305, and then transported to the connecting pipe 2 306 through the pump 304. At this time, the electric valve 2 307 is controlled to rotate, so that the connecting pipe 2 306 is connected with the curved pipe 2 308 on the side of the replaced ceramic filter element 8, so that the wastewater is transported to the hollow tube 2 3 where the ceramic filter element 8 is replaced, and the wastewater continues to be filtered through the ceramic filter element 8 until the wastewater in the storage tank 301 is pumped out, and then the pump 304 is controlled to be turned off.
