The specific implementation mode is as follows:

the present invention will be explained in more detail by the following examples, which are intended to disclose all changes and modifications within the scope of the present invention, and the present invention is not limited to the following examples;

the waterway filtering device of the on-line analysis equipment comprises a cylinder body 1, wherein a top plate of the cylinder body 1 is provided with a water inlet 5 and a water outlet 6, the water inlet 5 is communicated with the cylinder body 1, water to be filtered is introduced into the cylinder body 1 for preparation of filtration, the bottom of the cylinder body 1 is provided with a flange cover plate 14, an inner cylinder 4 is arranged inside the cylinder body 1, one end of the inner cylinder 4 is fixed on the top plate of the cylinder body 1 in any known technology mode and is communicated with the water outlet 6, and the other end of the inner cylinder 4 is provided with an opening; the inner cylinder 4 divides the inside of the whole cylinder body 1 into two parts, the outside of the inner cylinder 4 is a part to be filtered, the inside of the inner cylinder 4 is a part which is being filtered or is well filtered, a water outlet is communicated with the inner cylinder 4, a filter cylinder 8 with an open bottom and a plurality of water permeable holes in the side surface and the top surface is arranged in the inner cylinder 4, a first filter disc 15 with a diameter larger than that of the inner cylinder 4 and a plurality of second through holes 17 is arranged at the opening end of the inner cylinder 4, the open end of the filter cylinder 8 is buckled on the first filter disc 15 and fixedly connected with the first filter disc 15 through a connecting component, one end of the connecting component is connected with a flange cover plate 14, the other end of the connecting component pushes the first filter disc 15 against the opening end of the inner cylinder 4, the connecting components have two functions, one is to fix the filter disc 15 and the filter cylinder 8 into a whole, the other is to tightly push the first filter, in fact, the device is provided with two filtering devices, the first filtering is actually realized through the first filter disc 15, water to be filtered enters the filter cartridge 8 through the second through holes 17 on the first filter disc 15, the second through holes 17 block large impurities outside, the second filtering is realized through the filter cartridge 8, and the water entering the filter cartridge 8 further passes through the through holes 20 on the filter cartridge 8 and finally flows out from the water outlet 6.

In order to further improve the filtering effect of the device, when the filter cartridge 8 is selected, the diameter of the filter cartridge 8 is slightly smaller than that of the inner cylinder 4, the filter cartridge 8 can be easily installed in the inner cylinder 4 during installation, so that the gap between the filter cartridge 8 and the inner cylinder 4 is not too large, if the diameter difference between the filter cartridge 8 and the inner cylinder 4 is large, the part of water entering from the first filter disc 15 directly enters the inner cylinder 4, and is directly discharged from the water outlet 6 without being filtered by two filtering paths of the filter cartridge 8, and the filtering effect is poor.

The diameter of the water-permeable holes on the filter cartridge 8 is smaller than that of the second through holes 17 on the first filter disc 15, so that the impurities which are not filtered in one filtration can be filtered out in the second filtration.

The connecting assembly comprises a screw 9, an upper bolt 10 and a lower bolt 12 which are arranged on the screw 9 and used for limiting the filter cartridge 8 and the first filter disc 15, the lower end of the screw 9 is connected with a flange cover plate 14, the screw 9 is supported by the flange cover plate 14, the first filter disc 15 is tightly propped against the opening end of the inner cylinder 4, a through hole 20 for the screw 9 to pass through is formed in the middle of the top surface of the filter cartridge 8, and a first through hole 18 for the screw 9 to pass through is formed in the middle of the first filter disc 15.

According to the amount and the size of impurities in water to be filtered, a second filter disc 16 with the same structure as the first filter disc 15 is further arranged between the first filter disc 15 and the lower bolt 12, the lower bolt 12 is used for fixing the first filter disc 15 and the second filter disc 16, meanwhile, the lower bolt 12 can be adjusted according to the water source condition, and then the first filter disc 15 and the second filter disc 16 are relatively rotated, so that the filter disc 15 is formed; the aperture of the second through hole 17 on the filter 16 can be shielded, namely the aperture of the second through hole 17 can be reduced, and the filter is suitable for filtering water sources with fine impurities.

In order to assemble the filter cartridge 8 and the first filter disc 15 and/or the second filter disc 16 quickly during installation, save adjustment time and enable the first filter disc 15 to be tightly pressed against the open end of the inner cylinder 4, the screw 9 is welded with the middle bolt 11, the middle bolt 11 is positioned at the first filter disc 15, so that the middle bolt 11 limits the position of the first filter disc 15, during installation, the first filter disc 15 is pressed against the middle bolt 11, the filter cartridge 8 is buckled on the first filter disc 15, the lower bolt 12 is screwed at the moment, or after the second green disc 16 is installed, the lower bolt 12 is screwed, the upper bolt 10 is screwed, and the whole filter core is assembled.

The spring 13 in a compressed state is arranged between the screw 9 and the flange cover plate 14, the spring 13 in the compressed state provides a certain fault tolerance rate for installing the filter core, errors cannot be avoided because the length of the screw 9 and the welding of the middle bolt 11 can be determined by measurement in advance, and meanwhile, the compressed spring 13 provides an upward force for the screw 9 to press the first filter disc 15 at the opening end of the inner cylinder 4.

In order to avoid the air existing in the inner cylinder 4, an air release valve 7 is arranged, and the air release valve 7 is positioned on the top plate of the cylinder 1 and is communicated with the inner cylinder 4.

This filter equipment is detachable, filters one end time after, need dismantle and wash, but how to know the device and need wash woolen cloth, all be equipped with water pressure gauge 19 on then needing water inlet 5 and the delivery port 6 and judge, according to the difference between two water pressure gauges 19, just can roughly judge whether need wash.

Further, the barrel 1 comprises an upper barrel 2 and a lower barrel 3, the diameter of the upper barrel 2 is larger than that of the lower barrel 3, the diameter of the lower barrel 3 is larger than that of the inner barrel 4, as shown in fig. 1, a water source from the water inlet 5 falls on a connecting table top of the upper barrel 2 and the lower barrel 3 and does not directly impact on the flange cover plate 14, the flange cover plate 14 is actually protected, in addition, after the water flow impacts the table top, the water flow direction faces to the central axis of the upper barrel 2, and at this time, the lower surface of the first filter disc 15 or the second filter disc 16 is washed, so that the blocking probability of the filter discs 15 or 16 is reduced.

The details of the above are not described in detail since they are prior art.
