DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1:

[0029] Reference Figure 1-7 A filter device capable of detecting blockage includes a pipeline 101 and a pipeline 102, and also includes: a mounting plate 3 connected between the pipeline 101 and the pipeline 102; a filter plate 301 mounted in the mounting plate 3, the filter plate 301 is used to filter the liquid in the pipeline 101 and the pipeline 102; two groups of pressure sensors 103 are respectively mounted in the pipeline 101 and the pipeline 102; an electronic valve 104 is mounted in the pipeline 101, the pipeline 101 is the liquid inlet end, the pipeline 2 102 is the liquid outlet end, and flanges are provided on the pipeline 101 and the pipeline 2 102.

[0030] When in use, pipeline 1 101 and pipeline 2 102 are installed at the discharge end of the chemical liquid through the flange. The mounting plate 3 is used to connect pipeline 101 and pipeline 2 102, and fill and seal the gap to avoid leakage. This device is suitable for coarse filtration in the previous process. During filtration, larger impurities will be intercepted at the filter plate 301. At this time, with the accumulation of impurities, the liquid discharge rate will gradually decrease. At this time, the pressure sensors 103 on both sides of the filter plate 301 will send data with large differences. At this time, it can be known that blockage has occurred here and needs to be processed. At this time, the electronic valve can be closed to prevent the flow of liquid, and the filter plate 301 can be cleaned.

[0031] Embodiment 2:

[0032] Reference Figure 1-7, a filter device capable of detecting blockage, which is basically the same as Example 1, and further, the filter plates 301 on the mounting plate 3 are divided into two groups, the filter plates 301 located at the bottom are located between the pipeline 101 and the pipeline 2 102, the pipeline 2 102 is fixedly connected with a telescopic rod 105, the telescopic end of the telescopic rod 105 is connected to the mounting plate 3, the pipeline 101 and the pipeline 2 102 are fixedly connected with an electromagnetic ring 201, a cavity is provided in the electromagnetic ring 201, an electromagnetic block 202 is slidably connected in the cavity, and the electromagnetic block 202 is electromagnetically connected. The ring 201 can be moved due to the change in magnetic force. A rubber strip 203 is fixedly connected to the electromagnetic block 202. The rubber strip 203 is used to seal the gap between the mounting plate 3 and the pipeline. A mounting seat 303 is provided on the mounting plate 3. The filter plate 301 is installed on the mounting seat 303. A mounting piece 304 is provided on the side of the filter plate 301 away from the mounting seat 303. The mounting piece 304 is used to fix the filter plate 301. Rubber strips 302 are provided on both sides of the mounting plate 3. The rubber strips 302 are used to seal the gap between the mounting plate 3 and the pipeline.

[0033] When a blockage occurs, the electronic valve 104 can be controlled to prevent the liquid from entering the pipeline, and then the magnetic field inside the electromagnetic ring 201 is changed. At this time, the rubber strip 203 that is initially close to the mounting plate 3 will be moved away from the mounting plate 3 under the action of the electromagnetic block 202. At this time, the telescopic rod 105 can drive the mounting plate 3 to move, so that the filter plate 301 initially located at the top moves downward, and the blocked filter plate 301 will move downward until the unblocked filter plate 301 moves between the pipeline 1 101 and the pipeline 2 102, and the telescopic rod 105 stops moving. At the same time, the electromagnetic ring 201 changes the magnetic field again, and the electromagnetic block 202 moves again through the magnetic field, so that the rubber strip 1 203 is again in close contact with the mounting plate 3. At the same time, the contact between the rubber strip 2 302 and the electromagnetic ring 201 together plays a sealing effect to reduce liquid leakage. Then the staff can come to the device and clean the filter plate 301 by reverse spraying water. When the upper filter plate 301 is blocked next time, the upper filter plate 301 can be moved out again and filtered through the lower filter plate 301.

[0034] During the movement of the mounting plate 3, liquid in some pipes may drip through the gaps. At this time, the user may place a collection bucket under the mounting plate 3 to collect the liquid and reduce the waste of resources.

[0035] At the same time, due to the setting of the electromagnetic ring 201, this device is suitable for the first stage of coarse filtration. Since coarse filtration is most likely to be blocked, it can effectively reduce the slow flow rate of liquid caused by blockage, making it easier to filter the chemical liquid at a faster time. If it is installed in the subsequent fine filtration, since the electromagnetic ring 201 needs to be continuously energized, it is easy to waste electricity resources.

[0036] And during subsequent maintenance, the rubber strips need to be checked frequently to reduce the possibility of leakage.

[0037] The utility model is provided with a pressure sensor 103. When in use, it can determine whether the filter plate 301 is blocked by the pressure difference between the two groups of pressure sensors 103, so that the user can quickly know the blocking position and then clean and dredge the blocking position, which effectively reduces the time of slow flow rate caused by blockage and is convenient for use.

[0038] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
