Detailed Description

The pipeline filter for filtering titanium liquid as shown in fig. 1-7 comprises a pipe body 1, wherein the left end and the right end of the pipe body 1 are respectively connected with a flushing port 2 and a titanium liquid outlet 3 through flanges, a titanium liquid inlet 4 is fixedly connected to the position above the pipe body 1 and close to the flushing port 2, a sewage outlet 5 is fixedly connected to the position below the pipe body 1 and close to the titanium liquid outlet 3, the flushing port 2 and the sewage outlet 5 are externally connected with a normally closed ball valve, and the titanium liquid inlet 4 and the titanium liquid outlet 3 are connected in series between titanium liquid conveying pipelines through the normally open ball valve; a filtering component is arranged in the pipe body 1; the filter assembly comprises a cage 6, a filter cartridge 7 and a rubber sealing sleeve 8, wherein the cage 6 is cylindrical, the outer diameter of the cage is smaller than the inner diameter of the pipe body 1, and the length of the cage is equal to that of the pipe body 1; the rubber sealing sleeve 8 comprises a sleeve body 81 and a lip edge 82 which is connected with the sleeve body 81 into a whole; the filter cartridge 7 is a folded filter cartridge made of flexible filter cloth through sewing; the sleeve body 81 is sleeved at two ends of the cage 6, the circumferential outer surface of the sleeve body 81 is fixedly connected with two ends of the filter cartridge 7, the filter cartridge 7 is sleeved and attached to the cage 6, and the lip edge 82 is pressed between flanges of the flushing port 2 or the titanium liquid outlet 3. The liquid before filtering is prevented from short-circuiting and entering the interior of the filter bag. The flushing port 2 is externally connected with a tee joint 9, and the other two ports of the tee joint 9 are respectively connected with a thin titanium liquid pipe and a compressed air pipe through valves. The filter assembly further comprises a plurality of retaining rings 10, the retaining rings 10 being fitted around the outside of the filter cartridge 7.

Brief description of installation and use:

1. a pp ball valve is arranged at the titanium liquid inlet and used for controlling the titanium liquid to enter the filter and needs to be closed when being cleaned;

2. a pp ball valve and a sewage discharge pipeline are arranged on the sewage discharge port flange, the valve is in a normally closed state during filtering work, and the valve needs to be opened during cleaning;

3. a pp ball valve is installed at the outlet of the filtered titanium liquid and connected with a pipeline for conveying the filtered titanium liquid, and the filtered titanium liquid needs to be closed when being cleaned;

4. the back flushing inlet is provided with a tee joint through a flange and is used for gas back flushing and liquid back flushing during back flushing, when the filter starts to reversely clean the filter bag, the titanium liquid inlet valve is closed, the titanium liquid outlet valve after filtration is closed, the drain outlet valve is opened, the compressed air valve or the light titanium liquid valve at the back flushing inlet is opened, and gas back flushing or liquid back flushing is performed during reverse cleaning. And after the reverse washing is finished, closing the drain outlet valve.

5. When liquid is backwashed, the compressed air pipeline can be closed or not, but the pressure of the compressed air is far greater than that of the dilute titanium liquid.

When the pipe works normally, titanium liquid enters the pipe cavity of the pipe body 1 from the titanium liquid inlet 4, the titanium liquid passes through the material gap of the filter cylinder 7 and enters the interior of the filter cylinder 7, impurities are left outside the filter cylinder 7, and the titanium liquid after the impurities are filtered is discharged from the titanium liquid outlet 3 and is conveyed in a pipeline continuously.

The pipe filter of this embodiment has the following characteristics:

1. the volume of traditional filter is generally comparatively huge, and this filter volume is less, installs the use additional when being fit for installing in the narrow region in space or being used for the later stage repacking pipeline.

2 the filter has low processing and manufacturing difficulty and is convenient to disassemble and maintain.

3. After traditional filter filtration, need the manual work to clear up the filter screen, this filter uses compressed air and spent acid for washing power, need not to dismantle, can realize closed reverse washing.

4. The filter is provided with a bottom sewage outlet, so that closed sewage discharge can be realized, the pollution condition caused by liquid leakage can be avoided, and the cleanness of the operation environment can be favorably realized.

5. This filter internally mounted has the filtration skeleton for the installation of filtration filter bag and the support to the filter bag, when filtering filter bag filtering quality decline and no regeneration value, only need dismantle one end and seal the flange screw, can realize taking out of inside skeleton and filter bag and change, the maintenance degree of difficulty is low, and maintenance duration is short and intensity of labour reduces.

6. Before the filter bag inside the filter is replaced, the liquid in the filter can be completely emptied, no medium exists in the filter, and the situations of overflowing or spilling of the medium inside the filter and the like are avoided.

7. The filter shell can be made of pp materials, and the internal supporting cage can also be a multi-strand framework made of pp materials, so that the filter is simple and convenient to prepare and is corrosion-resistant; the filter cartridge is a pleated filter bag, so that the filtering surface area is large and the efficiency is high.
