DETAILED DESCRIPTION

[0022] The embodiments of the present application will be described in detail below with the accompanying drawings and examples, so that the realization process of how the present application applies technical means to solve technical problems and achieves technical effects can be fully understood and implemented.

[0023] As Figures 1-6As shown, the deep-sea fish oil processing vacuum feeding machine filtering structure provided by the embodiment comprises a filtering shell 1 and a multi-layer filter screen assembly 2. The filtering shell 1 is in a cylindrical structure. The filtering shell 1 is respectively connected with an inlet 3 and an outlet 4 at two ends. A plurality of installation openings 5 are formed on the outer side of the filtering shell 1. The multi-layer filter screen assembly 2 comprises a sealing arc plate 201, a sealing frame 202 and a filter screen 203. The filter screen 203 is fixedly installed in the filter screen 203 frame. The sealing arc plate 201 is fixedly connected with the top of the sealing frame 202. The installation openings 5 are respectively provided with quick connection assemblies 6 at two ends. A plurality of pressure sensors 7 are fixedly installed on the two sides of the multi-layer filter screen 203. An equipment bin 8 is arranged on the outer side of the filtering shell 1. A detection module 9 is fixedly installed in the equipment bin 8. The sensor is electrically connected with the detection module 9. A sliding groove 10 is formed on the side of the filtering shell 1. The quick connection assembly 6 comprises a buckle 601, a sliding block 602 and a spring 603. The sliding block 602 slides in the sliding groove 10. The spring 603 is respectively in contact with the sliding groove 10 and the sliding block 602 at two ends. The buckle 601 is fixedly connected with the sliding block 602. A clamping opening 11 is formed on the two sides of the sealing arc plate 201. A fastening assembly 12 is fixedly connected with the outer side of the filtering shell 1. The fastening assembly 12 comprises a fixed block 1201 and a fastening screw 1202. The fastening screw 1202 is threadedly connected with the buckle 601 penetrating through the fixed block 1201. A large-angle chamfer is formed on one side of the bottom of the buckle 601. The bottom of the buckle 601 is tightly attached to the sealing arc plate 201. An extrusion plate 13 is fixedly connected with the two sides of the sealing arc plate 201. The one end of the buckle 601 is in contact with the extrusion plate 13. The side of the sealing frame 202 and the inner hole of the filtering shell 1 are both inverted trapezoidal. A sealing bin 16 is arranged on the outer side of the installation opening 5. The fish oil passes through the filtering structure before entering the feeding machine. The oil enters from the inlet 3, passes through the multi-layer filter screen assembly 2 and then flows out from the outlet 4. The passing area of the filter screen 203 is larger than the area of the inlet 3. The pressure sensors 7 on the two sides of the filter screen 203 detect the pressure between the inlet 3, the outlet 4 and the two filter screens 203 in real time. When the reading of the pressure sensor 7 is abnormal, it is judged that the multi-layer filter screen assembly 2 has a problem. The corresponding filter screen 203 is disassembled according to the abnormal position. When disassembling, the fastening screw 1202 is loosened so that the fastening screw 1202 is separated from the buckle 601. At this time, the sealing arc plate 201 is lifted up under the elastic force of the internal sealing strip. Since the sealing arc plate 201 is tightly attached to the lower bottom surface of the buckle 601, the buckle 601 is difficult to reset after the sealing arc plate 201 is lifted up. At this time, the filter screen 203 is replaced. After the replacement is completed, the filter screen 203 frame is inserted into the installation opening 5. Then the fastening assembly 12 pulls the buckle 601. The sealing arc plate 201 is pressed down under the action of the buckle 601. After the buckle 601 contacts with the extrusion plate 13, the fastening assembly 12 is continuously twisted so that the sealing arc plate 201 is stretched along the surface of the filtering shell 1. The sealing arc plate 201 and the filter screen 203 frame are tightly sealed with the filtering shell 1.

[0024] As shown in Figure 4 And Figure 6 The quick plug assembly 14 is fixedly installed on one side of the sealing frame 202, and the filter screen 203 is provided with a pin hole 15 at each corner, and the outer end of the pin hole 15 is provided with a tapered chamfer. The quick plug assembly 14 includes a No. 1 spring 1401, an outer sleeve 1402, a sliding column 1403, and a folding piece 1404. The outer sleeve 1402 is fixedly connected with the sealing frame 202, the sliding column 1403 slides along the inner wall of the outer sleeve 1402, one end of the No. 1 spring 1401 is fixedly connected with the bottom of the outer sleeve 1402, the other end of the No. 1 spring 1401 is fixedly connected with the sliding column 1403, and the two ends of the folding piece 1404 are respectively fixedly connected with the outer sleeve 1402 and the sliding column 1403. When disassembling, the disassembling tool is connected with the sliding column 1403, and the sliding column 1403 is pulled outward. After the folding piece 1404 is straightened, the filter screen 203 can be disassembled. In the installed state, the folding piece 1404 is in a folded state under the tension of the No. 1 spring 1401, and the folding piece 1404 is attached to the outer side of the pin hole 15 to fix the filter screen 203.

[0025] The different levels of filter screens 203 are separately disassembled through the multi-layer filter assembly, and the pressure between the inlet 3, the outlet 4 and the two filter screens 203 is detected in real time through the pressure sensor 7. When the reading of the pressure sensor 7 is abnormal, it is judged that the multi-layer filter screen assembly 2 has a problem, the corresponding filter screen 203 is disassembled according to the abnormal position, the single-layer filter screen 203 is replaced, and the quick connection assembly 6 is used to quickly disassemble and assemble in the case of abnormality, so as to simplify the operation process and reduce the maintenance time.
