As shown in fig. 1 and 3, each of the filtering units 1 comprises an oil outlet valve 13, an oil inlet valve 6, a tube plate 14, a filtering shell 15 and a filtering core 16, wherein the filtering core 16 is arranged in the filtering shell 15, the tube plate 14 is arranged on the upper part of the filtering shell 15, the PLC control box 11 is further arranged on the front side of the frame 12, the full-automatic internal source backwashing filter comprises a plurality of filtering units, the oil inlet valve 6 is arranged at the bottom of each group of filtering units 1, and when filtering, liquid is distributed to each filtering unit 1 from bottom to top to filter after keeping a certain pressure and entering from the inlet header pipe 4, clean liquid penetrates through the filtering core 16 from outside to inside, and particles are intercepted on the outer surface of the filtering core 16 to form a filter cake. As filtration proceeds, the build-up of the filter element 16 surface increases and the differential pressure across the filter increases, and the filter system automatically enters a backwash regeneration process when a predetermined pressure drop is reached. And backwashing by using the filtered clean crude oil, after backwashing for a period of time, re-closing the drain valve, re-opening the inlet valve, and ending backwashing and putting the first filtering unit into operation again. And then backwashing the next filter unit in sequence until all the filter units in the system are backwashed and the filter system recovers to a normal operation state. Because only one filter unit is operated in backwashing during backwashing, and other filter units are still in a filtering state, the continuity of process operation can be ensured, after the filter element is blocked, external medium backwashing is not needed, after the filter element is blocked, manual operation is not needed, the system is automatically flushed, dirt, protective equipment and production cost are more effectively removed, crude oil is efficiently utilized, the environment is protected, and the utilization rate is improved by 99%.

As shown in fig. 5, the adjustable sealing assembly 2 includes an installation box 202, the installation box 202 is disposed in the middle of the steam inlet 10, a baffle 201 is slidably installed at one end of the installation box 202, a lead screw 204 is installed at the other end of the installation box 202 through a lead screw thread sleeve 203, one end of the lead screw 204 is rotatably disposed on the baffle 201, a turntable 205 is fixedly installed at the other end of the lead screw 204, when the size of the steam inlet needs to be controlled, the lead screw 204 is rotated at the time, and because the lead screw 204 is installed at the other end of the installation box 202 through the lead screw thread sleeve 203, one end of the lead screw 204 is rotatably disposed on the baffle 201, and the turntable 205 is fixedly installed at the other end of the lead screw 204, so that the lead screw 204 can be moved by matching with the lead screw thread sleeve 203, when the lead screw 204 is moved, the baffle 201 is driven to be moved, the size of the space where the baffle 201 blocks the installation box 202 is changed, thereby controlling the size of the steam inlet 10 to perform gas, and controlling the size of the steam inlet 10, thereby improving convenience of the device.

The working principle of the tube array type automatic back-flushing filter for the refining device is as follows:

when in use, the full-automatic internal source backwashing filter consists of a plurality of filtering units, and the bottom of each group of filtering units is provided with an oil inlet valve and a blow-down valve. During filtering, liquid is distributed to each filtering unit from bottom to top for filtering after the liquid enters from the inlet header pipe under a certain pressure, clean liquid penetrates through the filter element from outside to inside, and particles are intercepted on the outer surface of the filter element to form a filter cake. As the filtering is carried out, the aggregate on the surface of the filter element is increased, the differential pressure of the filter is gradually increased, and when the preset pressure drop is reached, the filtering system automatically enters a back washing regeneration process. And backwashing by using the filtered clean crude oil, after backwashing for a period of time, re-closing the drain valve, re-opening the inlet valve, and ending backwashing and putting the first filtering unit into operation again. And then backwashing the next filter unit in sequence until all the filter units in the system are backwashed and the filter system recovers to a normal operation state. Because only one filter unit is operated in backwashing in the backwashing process, and other filter units are still in a filtering state, the continuity of process operation can be ensured, after the filter element is blocked, no external medium is needed for backwashing, after the filter element is blocked, no manual operation is needed, the system is automatically flushed, dirt, protective equipment and production cost are effectively removed, crude oil is efficiently utilized, the environment is protected, and the utilization rate is improved by 99%. And this device is when the size of steam inlet needs to be controlled, this moment through rotating lead screw 204, and because the lead screw 204 is installed through lead screw swivel nut 203 to the mounting box 202 other end, lead screw 204 one end is rotated and is set up on baffle 201, lead screw 204 other end fixed mounting has carousel 205, make lead screw 204 cooperate lead screw swivel nut 203 can make lead screw 204 remove, when lead screw 204 removes, thereby can drive baffle 201 and remove, the space size that makes baffle 201 plug up mounting box 202 changes, thereby can control steam inlet 10 and carry out gaseous size, control steam inlet 10, the convenience of this device has been improved.

The above-mentioned embodiments of the present invention are provided for illustrative purposes only and are not intended to limit the present invention, and various modifications and changes in other forms will be apparent to those skilled in the art based on the foregoing description.
