As shown in fig. 1 to 7, a multi-stage gel blocking filter 31 according to a first embodiment of the present utility model is applied to gel filtration, and includes a housing 10 and a filter assembly 20 mounted inside the housing 10 to achieve a filtering effect.

Referring to fig. 1 to 6, a casing 10 is designed in a shape of a circular truncated cone, and includes a housing 11, a cover plate 12 disposed at a front end of the housing 11, and a supporting base 13 fixed at a lower end of the housing 11, wherein a cavity 14 is formed between the housing 11 and the cover plate 12, and a connecting groove 141 is concavely formed inside the cavity 14; the cover 12 is detachably assembled and connected to the front end of the housing 11 by means of a screw connection, a snap connection, or the like, so that the cover 12 is opened to expose the cavity 14. A liquid inlet hole 15 is formed in the center of the rear end face of the machine shell 10 in a penetrating manner, a liquid outlet hole 16 and a circulating hole 17 are formed in the side wall of the machine shell 10 in a penetrating manner, wherein the liquid outlet hole 16 and the circulating hole 17 are symmetrically distributed on the side face of the machine shell 10, and a sufficient distance between the liquid outlet hole 16 and the circulating hole 17 is ensured, so that the liquid outlet hole 16 and the circulating hole 17 are not mutually influenced; further, a liquid inlet pipe 151 is connected to the liquid inlet hole 15, a liquid outlet pipe 161 is connected to the liquid outlet hole 16, a circulating pipe 171 is connected to the circulating hole 17, gel to be filtered enters the cavity 14 through the liquid inlet pipe 151 and is filtered in the cavity 14, and then the gel can be filtered again through the circulating pipe 171 in a circulating way, or the gel leaves the shell 11 through the liquid outlet pipe 161 to finish the filtration. In order to avoid leakage, a connection joint 152 is fixedly arranged in the liquid inlet hole 15, one end of the liquid inlet pipe 151 is connected with the connection joint 152 to connect the liquid inlet pipe 151 with the cavity 14, and a sealing ring (not shown in the figure) is arranged between the liquid inlet pipe 151 and the connection joint 152.

Referring to fig. 3 and 7, the filter assembly 20 includes a plurality of annular filter screens 21, wherein connecting members 22 are fixedly arranged at front and rear ends of the filter screens 21, and the connecting members 22 are clamped in the connecting grooves 141 to assemble the filter screens 21; further, the radii of the filter screens 21 are not uniform, and a plurality of filter screens 21 are coaxially arranged and are overlapped from inside to outside; a gap is reserved between the filter screens 21 and the filter screen 21, so that a space for gel to flow is provided; the filter screen 21 is perforated with filter holes 211 for filtering, and the filter holes 211 on adjacent filter screens 21 are staggered; since the filter holes 211 are staggered, the gel can collide with the next filter screen 21 to be blocked after passing through the filter holes 211 of the first filter screen 21 in the axial direction, so as to avoid directly passing through the multiple filter screens 21, and further improve the filtering effect.

As shown in fig. 8, in actual use, the filtration system 30 is formed to complete the filtration of the gel; the filtering system 30 comprises a gel multistage blocking filtering device 31, a heating tank 32, a first tank 33 and a second tank 34; the liquid inlet pipeline 151 of the gel multistage separation filter device 31 is connected with the first trough 33, the heating trough 32 is arranged on the liquid inlet pipeline 151, and meanwhile, the pump body 35 is arranged on the liquid inlet pipeline 151, so that the gel is ensured to have enough power flow; the circulating pipeline 171 of the gel multistage blocking filter device 31 is connected with the first trough 33; the liquid outlet pipeline 161 of the gel multistage blocking filter device 31 is connected with the second trough 34; and switch valves 36, in particular solenoid valves, are provided on the liquid inlet pipe 151, the liquid outlet pipe 161 and the circulation pipe 171 to control the flow direction of the gel in the filtration system 30; a pressure gauge 37 for detecting pressure is also provided on the inlet line 161.

The above-mentioned filtration system 30 works on the principle that: the gel which is not filtered is placed in the first trough 33, and enters the gel multistage blocking and filtering device 31 through the liquid inlet pipeline 151 for filtering; if the gel after the filtration does not meet the requirement, the gel can be filtered again through the circulating pipeline 171, so that the filtration effect is improved; if the gel after the filtration reaches the requirement, the gel directly enters the second trough 34 through the liquid outlet pipeline 161 to complete the filtration.

The gel multistage blocking filter device 31 can optimize the filtering effect and improve the filtering efficiency; specifically, a plurality of filter screens 21 are adopted for the filter assembly 20 with a stacked structure, and the filter holes 211 on the adjacent filter screens 21 are staggered, so that the passing difficulty is increased to improve the filtering effect, and the size of the filter holes 211 can be adjusted according to the actual use condition to realize multi-stage filtration; in addition, a liquid inlet pipe 151, a liquid outlet pipe 161 and a circulating pipe 171 are arranged to be matched with various valve body pump bodies 35, so that the filtering effect is further improved.
