Description

TECHNICAL FIELD

[0001] The utility model relates to polymer filter technical field, especially a kind of polymer filter filter core's disassembly-free cleaning device. BACKGROUND

[0002] Polymerization reaction efficiency of polyamide 6 is about 90%, and 10% monomers and oligomers are in the chip particles after melt casting, which need to be separated by extraction tower, so that the polymer is separated from water. The extraction system used by our company is a three-effect extraction system, and the extraction water and chip particles are transported in reverse. The monomers and oligomers in the extraction water are extracted by high-temperature extraction water circulating extraction.

[0003] Due to the cutting of the chip, some dust will be generated during the conveying process due to friction and wear, and will be dissolved in the extraction water. The monomers and oligomers in the extraction water will also crystallize in the extraction tower and the dead angle of the conveying equipment and pipeline due to temperature changes, becoming larger solidified substances. These solidified substances will also dissolve in the extraction water after falling off. The particle-water separator at the top of the extraction tower cannot separate very small chip fragments, and chip fragments will also enter the circulating extraction water when the particle-water separator is damaged.

[0004] These situations will affect the quality of the chip and the extraction water, and will seriously affect the operation of the entire extraction system. Therefore, a filter needs to be installed in the circulating extraction water in the extraction tower to filter out impurities in the extraction water, including the above-mentioned dust, crystallized solidified substances, chips and chip fragments. After installing the filter, various impurities in the extraction water can be effectively filtered, greatly improving the quality of the chip and the extraction water, and ensuring smoother operation of the extraction system. However, the filter core inside the extraction water filter is blocked due to the large amount of filtered water, and the internal mesh needs to be frequently replaced and cleaned. Cleaning the filter core is very difficult, the system needs to be stopped, the filter tank needs to be emptied, the internal filter core needs to be removed, and then the filter core needs to be cleaned. Because the extraction water flows from the outside to the inside of the filter core, impurities are basically stuck on the outer wall of the filter core mesh. It is difficult for personnel to effectively clean it, and only hot water can be used for soaking, which is low in cleaning efficiency and takes several hours to clean once. Only one spare filter can be used for replacement.

[0005] Therefore, the utility model designs a polymer filter filter core's disassembly-free cleaning device to solve the above problems. Utility model content

[0029] In one specific embodiment of the technical scheme of the utility model:

[0030] Including filter tank body 1, water inlet pipe 2, steam pipe 3, flushing pipe 4 and filter core 5;

[0031] The filter tank 1 is a closed tank, a plurality of filter cartridges 5 are installed at the bottom of the inner cavity of the filter tank 1, the filter tank 1 is divided into two cavities by the filter cartridges 5, a water inlet pipe 2 is connected to the top of the filter tank 1, and a water outlet pipe 12 is connected to the bottom of the filter tank 1; a residue discharge pipe 11 is further arranged at the bottom of the filter tank 1, and the cavity outside the filter cartridges 5 is communicated with an external sewage pipe network through the residue discharge pipe 11;

[0032] The cavity outside the filter cartridges 5 is communicated with the water inlet pipe 2, the cavity inside the filter cartridges 5 is communicated with the water outlet pipe 12, and the water outlet pipe 12 is communicated with a downstream clean water pipe;

[0033] A water inlet valve 22 is further arranged on the water inlet pipe 2; the water inlet pipe 2 is connected with an external extraction water pipe through the water inlet valve 22, the water inlet pipe 2 is connected with a backflush valve 21 through a tee joint, and the inner cavity of the filter tank 1 is communicated with the outside through the backflush valve 21; the backflush valve 21 is between the water inlet valve 22 and the filter tank 1; in this way, the upstream unfiltered extraction water can be blocked through the water inlet valve 22, and the floating impurities can be discharged through the backflush valve 21, so that the floating objects are prevented from floating on the water surface during the discharge of the impurities, and the impurities that cannot be dissolved and always float and are finally cleaned are prevented from adhering to the bottom of the filter tank 1 when the impurity water is discharged; the floating objects are discharged in advance through the backflush valve 21, so that the situation is effectively avoided.

[0034] An exhaust valve 14 is further arranged at the top of the filter tank 1

[0035] The bottom of the filter tank 1 is further connected with a steam pipe 3, a drain valve 42 and a flushing pipe 4 through a four-way joint;

[0036] A steam valve 31 is arranged on the steam pipe 3, the steam valve 31 is connected with an external steam pipe, the steam pipe 3 is filled with water vapor with a pressure of 3 bar; the temperature inside the steam pipe 3 is 140℃; and a pressure gauge 32 is further arranged on the steam pipe 3. The filter cartridges 5 can be effectively cleaned by high-temperature and high-pressure reverse blowing of water vapor, the blowing effect can cover the entire filter cartridges 5, and the filter cartridges 5 can be reversely blown from bottom to top, so that most of the impurities adhered to the mesh holes can be effectively removed.

[0037] A flushing valve 41 is further arranged on the flushing pipe 4, and the flushing pipe 4 is connected with an external clean hot water pipe; the water temperature in the flushing pipe 4 is between 60℃ and 80℃; the impurities outside the filter cartridges 5 are flushed into the cavity outside the filter tank 1 by being reversely flushed into the filter cartridges 5 through the flushing pipe 4, so that the flushing water with impurities can be conveniently discharged through the residue discharge pipe 11, and the filter cartridges 5 and the filter tank 1 are cleaned. The flushing pipe 4 can not only flush but also soak and dissolve the impurities, so that the cleaning is more thorough. A valve is further arranged on the residue discharge pipe 11, and the impurities flushed into the cavity outside the filter cartridges 5 are discharged through the residue discharge pipe 11.

[0038] The drain valve 42 is communicated with the sewage pipe, and a small amount of impurities are left in the cavity inside the filter core 5, after the external impurities are discharged, the extraction water is put into the filter tank body 1 through the water inlet valve 22, the impurities inside the filter core 5 are discharged through the drain valve 42, and after the impurities are discharged, the filter can be used normally again.

[0039] It should be noted that:

[0040] 1, the filter core is blocked by the impurities intercepted by the filter screen, and the impurities are blocked outside the filter screen, so it is difficult to wash from outside to inside, and the impurities need to be broken to be small or dissolved to pass through the filter screen, and the reverse flushing avoids this situation, and the reverse flushing can make the impurities directly separate from the filter screen, and after the filter core is disassembled, only a high-pressure water gun can be inserted into the inside of the filter core 5 to perform reverse flushing, the filter core is placed flat after being disassembled, and the side of the filter core 5 in contact with the ground cannot be washed, and the filter core needs to be continuously rolled to be washed, and the device is integrally washed through the flushing pipe 4, and only the flushing valve 41 needs to be opened to perform reverse flushing;

[0041] 2, the filter core 5 cannot be disassembled and needs to be high-temperature and high-pressure steam blowing, and only low-temperature and high-pressure air gun blowing can be achieved, and the effect is greatly discounted, the device is in the filter tank body 1, high-temperature and high-pressure blowing and cleaning are performed through the steam pipe 3, the cleaning effect is obviously better than that of the existing disassembly and cleaning mode, and the cleaning effect is obviously better than that of the existing disassembly and cleaning mode.

[0042] 3, because the polymer is dissolved in water when the temperature is above 50 DEG C, and the polymer can be melted by high temperature, the device utilizes the characteristics to design the filter core 5 cleaning device, and the cleaning effect of the device is poor for impurities that cannot be dissolved, and therefore the device is used for cleaning of the polyamide 6 polymer.

[0043] In use, the water inlet valve 22 is closed, the extraction water in the filter tank body 1 is emptied, the steam valve 31 is opened, the steam pipe 3 is opened, the filter core 5 is reversely blown by high-temperature water vapor, the impurities are blown away from the filter core 5, and the excess gas is separated along the exhaust valve 14, so that the gas flow is kept from inside to outside, and the gas is blown from bottom to top.

[0044] After blowing for 10 minutes, the impurities are dissolved and separated from the filter core 5 by high temperature, and the impurities are separated faster by high-pressure gas flow, and the whole blowing process is ensured to keep the water vapor pressure stable through the pressure gauge 32.

[0045] Then close the steam valve 31, open the flush valve 41, by high temperature hot water from the inside to the outside flush filter core 5, will be immersed in the previous blowing off the impurities, and the filter core 5 also immersed, and hot water full of filter tank 1, during more impurities will be dissolved, also have some impurities floating, hot water continues to fill, until the backflush valve 21 begins to drain water, the floating impurities are discharged, until there is no floating impurities can be closed flush valve 41.

[0046] After soaking for half an hour, open the valve on the discharge pipe 11, the sewage into the wastewater recovery pipe network, all the discharge, close the discharge pipe 11, backflush valve 21, water valve 13, water valve 41 and steam valve 31, open the water inlet valve 22, the previous extraction water flush filter core 5, open the drain valve 42, with impurities of water through the drain valve 42 into the sewage pipe, clean after closing the drain valve 42, open the water outlet valve 13, the filter can be used normally.
