the suspender 18 comprises a vertical long rod 1801, the vertical long rod 1801 is connected with a cross rod 1802, one end of the cross rod 1802 far away from the vertical long rod 1801 is connected with a vertical short rod 1803, and one end of the vertical short rod 1803 far away from the cross rod 1802 is connected with a hook 1804 connected with a hanging ring 16.

Specifically, the drain outlet 8 is connected with a drain pipe, and the drain pipe is connected with a waste liquid tank.

Specifically, a 20-mesh, 40-mesh, 60-mesh or 80-mesh filter screen is installed in the first filter 5.

Specifically, a 20-mesh, 40-mesh, 60-mesh or 80-mesh filter screen is installed in the second filter 6.

Specifically, the first filter 5 and the second filter 6 are further connected with a pressure gauge, a differential pressure gauge and an explosion-proof operation panel.

Specifically, the top cover 11 is further provided with a sampling port.

The working principle of the utility model is as follows: the device can be used for cleaning tank bottom oil such as gasoline, diesel oil, methanol, xylene and the like. The device achieves the purpose of cleaning wax-like suspended matters and other impurities in the storage tank by circulating media of the storage tank for multiple times and filtering.

The first filter 5 and the second filter 6 are identical in structure, function and the like, and the only difference is that the mesh number of the filter screens 7 arranged in the first filter 5 and the second filter 6 is identical at the beginning, and the mesh number of the filter screens 7 arranged in the second filter 6 after a plurality of times of filtration is larger than that of the filter screens 7 arranged in the first filter 5.

The tank is stored to around 2 metres before cleaning and the inlet 12 and outlet 9 are connected by a metal hose 13 and sampling is carried out for comparison before the apparatus is started to operate. The tank bottom oil is filtered by a first filter 5 and then filtered by a second filter 6; filtering nets with the same mesh number can be arranged in the first filter 5 and the second filter 6 for respectively and simultaneously filtering; it is also possible to use only one of the filters while the other is in use.

In the first filtering process: the installation is 20 mesh filter screens 7 in the first filter 5, and the installation is 20 mesh filter screens 7 in the second filter 6, later will filter the oil through export 9 through metal collapsible tube 13 again from import 12 entering first filter 5 and filter, filter repeatedly like this many times, until can't filter impurity, then with oil through export 9 temporary storage in a container, carry out the change of filter screen, filter for the second time: generally, a 40-mesh filter screen 7 is arranged in the first filter 5 after replacement, a 60-mesh filter screen 7 is arranged in the second filter 6 to prevent blockage, the filter screens 7 arranged in the first filter 5 and the second filter 6 can be both 40 meshes, the filter screen 7 arranged in the first filter 5 is replaced by the 40-mesh filter screen 7 when the third filtration is carried out, the 60-mesh filter screen 7 is arranged in the second filter 6, and then the filtered oil enters the first filter 5 from the inlet 12 through the outlet 9 and the metal hose 13 to be filtered, so that the filtration is repeated for multiple times until no impurities are filtered; then the sampling is compared with the sampling before the initial filtration, and the sampling is sent into a tank for storage after reaching the expected standard.

4 kinds of filter screens 7, 20 meshes, 40 meshes, 60 meshes and 80 meshes are prepared in the device. The filter screen 7 with 20 meshes is not blocked after being filtered for 24 hours, if the blockage is serious, the filter screen with 20 meshes needs to be replaced again to continue circulation, and sampling is carried out for comparison. After obvious change, the filter screen is changed to 40 meshes, and so on until the sampling is qualified. The method is expected to finish the cleaning of bottom oil impurities in 20-30 days for one tank.

The device is for changing the filter screen when opening, close top cap 11 convenient, 8 sets of bolts of top cap 11 installation altogether, 8 sets of bolts are enough to bear the pressure when filtering, too much dismantlement when not using top cap 11 on the contrary can be very troublesome, cause to open top cap 11 for a long time. 8 sets of bolts evenly install respectively on the dead lever on filter tube wall, can realize about 180 activities, open spout 17 on top cap 11 on screw rod installation relative position, make things convenient for bolt installation and dismantlement, unscrew the bolt, lift top cap 11 bolt and will follow spout 17 roll-off, need not to unscrew all bolts again, unusual convenience and labour saving and time saving.

The top cover 11 is provided with the hanging ring 16, so that the top cover 11 can be conveniently separated and reloaded in the process of installation and disassembly when the filter is cleaned, the labor is saved, and the safety is ensured.

The side of the bottom of the filter is provided with a drain outlet 8, the drain outlet 8 is connected with a drain pipe, and when the filter screen is replaced, nitrogen gas is required to be connected to blow the material to a waste liquid tank through the drain pipe connected with the drain outlet 8 to be collected, so that loss is reduced.

A boom 18 is designed between the two filters. A pillar is arranged on a base, a suspender 18 is arranged on the pillar, and the pillar and the suspender 18 use a movable connection mode to realize 360-degree all-directional rotation.

The hook 1804 and the hanging rod 18 are connected through bolts, the thread distance is large, the top cover 11 is convenient to separate and reinstall, and manpower is saved.

Normally, the filter screen is replaced when the pressure difference meter PDI is larger than 5 KPa. The pressure gauge monitors pressure, and the explosion-proof operation panel can play an explosion-proof role.

The top cover 11 is also provided with a sampling port through which a sample is taken.

The first filter 5 and the first filter 5 are both magnetic filters, with the specification DN100 PN20, standard SH3411-1999, process connection format RF SH/T3406.
