DETAILED DESCRIPTION
[0018] The present invention will be described in further detail below with reference to the accompanying drawings.
[0019] like Figure 1-6 As shown, the utility model provides a rectangular base plate 1 as the installation base of the filtering device, and an extraction shell 2 is installed on the front side of the upper end of the base plate 1, which serves as the shell of the conveying component and the container during the conveying process. A feed pipe 3 and a discharge pipe 4 are respectively installed on the front and rear sides of the outside of the extraction shell 2. A mounting frame 5 is provided at a position on one side of the interior of the extraction shell 2, and a diaphragm 6 is provided inside the mounting frame 5. The internal space of the extraction shell 2 is divided by the diaphragm 6 and the mounting frame 5, and a smaller part of the space inside the extraction shell 2 is used as a accommodating space for extracting the liquid or gas to be filtered. A push-pull rod 7 is installed on the side of the diaphragm 6 away from the feed pipe 3. The movement of the push-pull rod 7 drives the middle position of the diaphragm 6 to deform. When the middle of the diaphragm 6 moves toward the discharge pipe 4, the space between the diaphragm 6 and one side of the interior of the extraction shell 2 becomes smaller, so that the liquid or gas extracted into the interior of the extraction shell 2 can be squeezed out from the discharge pipe 4. When the space between the diaphragm 6 and one side of the interior of the extraction shell 2 becomes larger, the liquid or gas to be filtered is sucked from the feed pipe 3 into the interior of the extraction shell 2. A fixed plate 8 is provided inside the extraction shell 2. The fixed plate 8 is on the side of the mounting frame 5 away from the discharge pipe 4, and a movable hole 9 is provided on one side of the fixed plate 8 for use with the push-pull rod 7, so that one end of the push-pull rod 7 can pass through the fixed plate, and the push-pull rod 7 is limited by the movable hole 9. A servo motor 27 is installed on the side of the lower end of the interior of the extraction shell 2 away from the feed pipe 3. A reciprocating structure 10 is provided between the servo motor 27 and the push-pull rod 7. The reciprocating structure 10 drives the push-pull rod 7 to move back and forth to both sides. A processing barrel 11 is installed on the rear side of the upper end of the bottom plate 1, and a Y-shaped filter 12 is installed on the rear side of the discharge pipe 4 to perform preliminary filtration on the transported liquid or gas. The filter cartridge inside the Y-shaped filter is made of polytetrafluoroethylene, which is corrosion-resistant, has low viscosity, and has good filtering properties.
[0020] The utility model is provided with a feeding elbow 13 at the rear side of the Y-shaped filter 12, and the other end of the feeding elbow 13 connected to the Y-shaped filter 12 is plugged into the bottom end of the processing barrel 11, and a discharge pipe 14 is installed on the side of the upper end of the processing barrel 11 away from the feeding elbow 13 to discharge the liquid or gas processed in the processing barrel 11. The interior of the discharge pipe 14 and the interior of the feeding elbow 13 are connected to the interior of the processing barrel 11. When filtering medical gas (such as oxygen), a certain height of water can be filled in the processing barrel 11. According to the characteristic that oxygen is not easily soluble in water, the water can be discharged from the processing barrel 11. It can humidify and remove dust from oxygen. When filtering medical liquids, particles of different sizes can be placed from bottom to top in the processing barrel 11 and discharged from large to small to filter the medical liquid and remove impurities. Some impurities that cannot be filtered by the Y-shaped filter 12 can be filtered out. A one-way conveying structure 15 is provided inside the feed pipe 3 and the discharge pipe 4 to prevent backflow when conveying the medical liquid or gas to be treated. A flow meter 16 is provided inside the conveying elbow 13 to monitor the internal flow of the pipeline, so that the Y-shaped filter 12 can be cleaned in time when necessary.
[0021] The utility model is connected to a turntable 17 on the front side of the servo motor 27, and a toggle column 18 is installed at the edge of the front side of the turntable 17. A toggle ring block 19 used in conjunction with the toggle column 18 is installed at the other end of the push-pull rod 7 connected to the diaphragm 6. The middle of the toggle ring block 19 is rectangular, and the upper and lower edges inside the toggle ring block 19 are semicircular, spliced into a runway shape. The toggle column 18 is inserted into the interior of the toggle ring block 19. The rotation of the turntable 17 drives the toggle column 18 to move under the inner mountain of the toggle ring block 19. During the rotation of the toggle column 18, the push-pull rod 7 is driven to move back and forth to both sides, and the middle of the diaphragm 6 is driven to move back and forth to both sides, so that the substance to be filtered is sucked into the interior of the extraction shell 2 and then squeezed out. The other end of the push-pull rod 7 connected to the diaphragm 6 extends to the side of the fixed plate 8 away from the mounting frame 5. A sleeve 20 is installed inside the feed pipe 3 and the discharge pipe 4, a main clamping ring block 21 is provided on the front side of the sleeve 20, and a secondary clamping ring block 22 used in conjunction with the main clamping ring block 21 is provided on the rear side of the sleeve 20. A movable ball 23 is provided inside the sleeve 20, and the hole in the middle of the main clamping ring block 21 or the hole in the middle of the secondary clamping ring block 22 can be blocked by the forward and backward movement of the movable ball 23. A number of evenly distributed connecting holes 24 are provided on the rear side of the secondary clamping ring block 22. When the movable ball 23 blocks the hole in the middle of the secondary clamping ring block 22, the substance to be filtered can flow from the connecting holes 24 into the interior of the Y-shaped filter 12. A handle 25 is installed on the rear side of the base plate 1, and universal wheels 26 with self-locking function are installed on the front, back and both sides of the lower side of the base plate 1 to facilitate the movement of the filtering equipment.
[0022] During the specific implementation of the present invention, the feed pipe 3 is first connected to the container to be filtered, the flow meter 16 is turned on, and the servo motor 27 is started to drive the turntable 17. Driven by the reciprocating structure 10, the diaphragm 6 begins to deform back and forth to both sides. When the diaphragm 6 moves toward one side of the fixed plate 8, the space between the diaphragm 6 and the extraction shell 2 becomes larger. At this time, the movable balls 23 approach each other, and the movable balls 23 on the front side block the hole in the middle of the auxiliary clamping ring block 22 inside the feed pipe 3. The substance to be filtered enters the sleeve 20 inside the feed pipe 3 from the hole in the middle of the main clamping ring block 21 inside the feed pipe 3. Then, as the diaphragm 6 moves to the side away from the fixed plate 8, it is sucked into the substance to be filtered inside the extraction shell 2. The material is squeezed, and at this time, the two movable balls 23 move away from each other, and the hole in the middle of the main clamping ring block 21 inside the feed pipe 3 is blocked by the movable ball 23 to prevent the material from flowing back. The movable ball 23 inside the discharge pipe 4 blocks the hole in the middle of the auxiliary clamping ring block 22 inside the discharge pipe 4, and the material to be filtered inside the outer shell 2 is squeezed out from the connecting hole 24 opened on the auxiliary clamping ring block 22 in the discharge pipe 4. After preliminary filtration by the Y-shaped filter 12, it enters the interior of the feed elbow 13, and finally is processed by the processing barrel 11 and discharged from the interior of the discharge pipe 14. After using this filtering equipment to filter the medical liquid, it is necessary to introduce high-temperature gas into the interior after cleaning to dry the inside of the pipeline.
[0023] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
