Description

Technical Field

[0001] This utility model relates to the field of synthetic resin processing technology, and in particular to a filtration device for processing polymer materials. Background Technology

[0002] Synthetic resins are high molecular weight polymers artificially synthesized from small molecule monomers through polymerization reactions such as addition polymerization or condensation polymerization. During the production process, plate and frame filters are commonly used to filter the resin solution to remove trace solid impurities from the system.

[0003] Existing plate and frame filters typically consist of a pressurizing assembly, multiple filter plates and frames, and supporting slide rails. The pressurizing assembly presses several filter plates and frames together along the slide rails to form a seal, allowing the resin solution to pass through the filter cloth between the plates and frames under pressure, thus achieving filtration.

[0004] However, the equipment has obvious shortcomings in actual use: after filtration is completed and the pressure is removed from the pressurizing components, the pressure plates and frames are still tightly connected, requiring manual separation of the plates and frames, which is time-consuming and labor-intensive, and seriously affects the efficiency of plate and frame replacement. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to provide a polymer material processing and filtration device, which uses a mounting frame that can be adjusted at equal intervals to install plates and frames. After filtration is completed, the mounting frame can automatically separate the compacted plates and frames, thereby improving the efficiency of plate and frame replacement.

[0007] To achieve the above objectives, the first aspect of this utility model provides a polymer material processing and filtration device, comprising: a support frame, a placement frame assembly, a pressurizing assembly, a first plate frame, multiple second plate frames, and a third plate frame. The support frame has transmission chambers disposed on both sides. The placement frame assembly includes multiple placement frames, two sets of equidistant transmission mechanisms, and a connecting plate. The multiple placement frames are slidably mounted inside the two transmission chambers. The two sets of equidistant transmission mechanisms are mounted inside the two transmission chambers and connected to the multiple placement frames. The connecting plate is mounted between the two sets of equidistant transmission mechanisms. The pressurizing assembly is mounted between the support frame and the connecting plate. The first plate frame is inserted into the placement frame closest to the pressurizing assembly. The multiple second plate frames are inserted into their respective placement frames. The third plate frame is fixedly mounted on the side of the support frame away from the pressurizing assembly.

[0008] In addition, the polymer material processing and filtration device proposed above according to this utility model may also have the following additional technical features: Specifically, the equidistant transmission mechanism includes multiple first connecting shafts, second connecting shafts, first connecting rods, second connecting rods, and multiple third connecting rods. The multiple first connecting shafts are respectively fixedly installed on one side of the multiple placement frames. The second connecting shafts are fixedly installed on one end of the transmission chamber near the third plate frame. One end of the first connecting rod is rotatably connected to the outside of the first connecting shaft closest to the pressurizing component. One end of the second connecting rod is rotatably connected to the outside of the second connecting shaft. The center of each of the multiple third connecting rods is rotatably connected to the outside of the corresponding first connecting shaft.

[0009] Specifically, the first connecting rod and the third connecting rod, the second connecting rod and the third connecting rod, and the third connecting rod are rotatably connected to each other.

[0010] Specifically, the pressurizing assembly includes multiple telescopic rods and a lead screw, wherein the two ends of the multiple telescopic rods are respectively fixedly installed between the support frame and the connecting plate, the lead screw is threaded to the inner side of the support frame, and one end of the lead screw is rotatably connected to the connecting plate.

[0011] Compared with the prior art, the present invention has the following advantages: The present invention inserts the plate frame into the placement frame that can be adjusted synchronously and equally. When the pressurizing component pressurizes, the spacing of the placement frame shortens synchronously, so that the plate frame can be compacted more evenly. After the extrusion component contacts the pressure, the spacing of the placement frame increases, and the plate frame automatically separates, resulting in higher plate frame replacement efficiency.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The polymer material processing and filtration device of this utility model is described below with reference to the accompanying drawings.

[0025] like Figures 1-9As shown in the figure, a polymer material processing and filtration device according to an embodiment of the present invention is characterized by comprising: a support frame 1, a placement frame assembly 3, a pressurizing assembly 4, a first plate frame 5, a plurality of second plate frames 6 and a third plate frame 7.

[0026] It should be noted that the support frame 1 is placed perpendicular to the ground by means of legs. The legs can reduce the contact area between the support frame 1 and the ground, thereby increasing the stability of the support frame 1 during use.

[0027] Transmission chambers 2 are respectively installed inside both sides of the support frame 1.

[0028] The placement rack assembly 3 includes multiple placement racks 31, two sets of equidistant transmission mechanisms 32, and a connecting plate 33.

[0029] Multiple placement racks 31 are slidably installed inside the two transmission chambers 2, and two sets of equidistant transmission mechanisms 32 are installed inside the two transmission chambers 2 respectively. The equidistant transmission mechanisms are connected to the multiple placement racks 31, and the connecting plate 33 is installed between the two sets of equidistant transmission mechanisms 32.

[0030] The pressurizing component 4 is installed between the support frame 1 and the connecting plate 33. The first plate frame 5 is inserted into the inner side of the placement frame 31 closest to the pressurizing component 4. Multiple second plate frames 6 are respectively inserted into the inner side of the corresponding placement frame 31. The third plate frame 7 is fixedly installed on the side of the support frame 1 away from the pressurizing component 4.

[0031] It should be noted that the first frame 5 and the second frame 6 are inserted into the placement frame 31 by means of plugs that are fixedly connected on both sides. The width of the first frame 5 and the second frame 6 is greater than the overall width of the placement frame 31. When the spacing of the placement frame 31 shrinks, the first frame 5 and the second frame 6, the second frame 6 and the third frame 7 will first come into contact and be compacted.

[0032] It should be noted that a first liquid storage chamber 51 is provided on the side of the first plate frame 5 near the second plate frame 6, and a first filter cloth groove 52 is provided on the outer side of the first liquid storage chamber 51, and a first sealing ring 53 is installed on the outer side of the first filter cloth groove 52.

[0033] It should be noted that a second liquid storage chamber 61 is provided on both sides of the second plate frame 6, and a filter plate 62 is installed between the two second liquid storage chambers 61. A second filter cloth groove 63 is provided on the outer side of the two second liquid storage chambers 61, and a second sealing ring 64 is installed on the outer side of the two second filter cloth grooves 63.

[0034] It should be noted that a third liquid storage chamber 71 is provided on the side of the third plate frame 7 close to the second plate frame 6, and a third filter cloth groove 72 is provided on the outer side of the third liquid storage chamber 71. A pressure gauge 73 is installed on the top of the third liquid storage chamber 71.

[0035] It should be noted that filter cloth needs to be placed between these plates and frames before installation to enhance filtration. Additionally, each of the four corners of these plates and frames is equipped with a shaft and a slot to facilitate the positioning of the filter cloth.

[0036] It should be noted that the two ends of the connecting plate 33 are fixedly connected to the placement rack 31 closest to the pressurizing component 4 in the transmission chambers 2 on both sides, and the connecting plate 33 is connected to the telescopic end of the pressurizing component 4.

[0037] It should be noted that a feed pipe is connected to one side of the third plate frame 7, and a discharge pipe is connected to the bottom of the first plate frame 5. The resin solution storage tank is connected to the feed pipe through a gear pump, which can pump the resin solution into the third plate frame 7.

[0038] Specifically, when it is necessary to filter resin solutions, a polymer material processing filtration device is required for filtration.

[0039] First, insert the first plate frame 5 into the inner side of the placement rack 31 closest to the pressurizing component 4, and then insert multiple second plate frames into the corresponding placement racks 31 in sequence to complete the installation of the first plate frame 5 and the second plate frame 6.

[0040] Then, the pressurizing component 4 is activated to extend. The pressurizing component 4 pushes the connecting plate 33 to move closer to the third plate frame 7. At this time, the equidistant transmission mechanism 32 in the transmission chamber 2 drives all the placement racks 31 to begin to retract equidistantly toward the third plate frame 7, so that the first plate frame 5 and the second plate frame 6, the second plate frames 6, and the second plate frame 6 and the third plate frame 7 come into contact and are compacted.

[0041] Next, the resin solution storage tank is connected to the inlet pipe of the third plate frame 7 via a gear pump and hose, and the recovery tank is connected to the outlet pipe of the first plate frame 5. The gear pump is started, and the resin solution is fed into the third storage chamber 71 of the third plate frame 7. After being filtered through multiple layers of filter plates 62 and filter cloth, it finally flows into the first storage chamber 51 and into the recovery tank through the outlet pipe. Filtration is then complete.

[0042] Finally, the pressurizing assembly retracts, and the pressurizing assembly 4 drives the connecting plate 33 to move away from the third plate frame 7. At this time, the equidistant transmission mechanism 32 in the transmission chamber 2 drives all the placement racks 31 to unfold equidistantly away from the third plate frame 7, causing the compacted first plate frame 5, second plate frame 6, and third plate frame 7 to separate. Workers can then directly remove the first plate frame 5 and second plate frame 6 for cleaning and replacement.

[0043] In one embodiment of this utility model, such as Figure 2 As shown, the equidistant transmission mechanism 32 includes multiple first connecting shafts 321, second connecting shafts 322, first connecting rods 323, second connecting rods 324, and multiple third connecting rods 325.

[0044] Among them, multiple first connecting shafts 321 are fixedly installed on one side of multiple placement racks 31, second connecting shafts 322 are fixedly installed on one end of the transmission chamber 2 near the third plate frame 7, one end of the first connecting rod 323 is rotatably connected to the outside of the first connecting shaft 321 closest to the pressurizing component 4, one end of the second connecting rod 324 is rotatably connected to the outside of the second connecting shaft 322, and the center of multiple third connecting rods 325 is rotatably connected to the outside of the corresponding first connecting shaft 321.

[0045] The first connecting rod 323 and the third connecting rod 325, the second connecting rod 324 and the third connecting rod 325, and the third connecting rod 325 are respectively rotatably connected.

[0046] It should be noted that the first connecting rod 323 and the second connecting rod 324 have the same length, and the third connecting rod 325 has twice the length of the first connecting rod 323 and the second connecting rod 324.

[0047] It should be noted that the first connecting rod 323, multiple third connecting rods 325, and the second connecting rod 324 form a broken line by connecting them end-to-end. The vertices of this broken line are at the same horizontal level, and the length of the constituent line segments at both ends is half the length of the constituent line segment in the middle. When the spacing between the points at both ends of the broken line changes, since the points at both ends of the line segment and the midpoint of the constituent line segment in the middle of the broken line are always on the same horizontal line, that is, all the placement racks 31 are restricted by the transmission chamber 2 and are on the same horizontal line, the spacing of all the placement racks 31 will change synchronously. This will cause the spacing of the first plate frame 5, multiple second plate frames 6, and third plate frames 7 to change synchronously. When the spacing decreases, these plate frames are compacted; when the spacing increases, these plate frames automatically separate. The replacement of the plate frames is quicker and more convenient.

[0048] In one embodiment of this utility model, such as Figure 3 As shown, the pressurization assembly 4 includes multiple telescopic rods 41 and lead screws 42.

[0049] The telescopic rod 41 has two ends fixedly installed between the support frame 1 and the connecting plate 33, respectively. The lead screw 42 is threadedly connected to the inner side of the support frame 1, and one end of the lead screw 42 rotates with the connecting plate 33.

[0050] Specifically, the end of the lead screw 42 away from the connecting plate 33 has a handle. When the handle is turned, the lead screw 42 rotates and moves within the support frame 1, thereby driving the connecting plate 33 to move back and forth.

[0051] It should be noted that the pressurizing component 4 can also be replaced by setting an electric push rod between the support frame 1 and the connecting plate 33.

[0052] In summary, the polymer material processing and filtration device of this utility model guides the originally disordered plates and frames through an orderly placement rack, achieving automatic separation after compaction without the need for manual separation of the compacted plates and frames, which facilitates quick replacement of the plates and frames.
