Description

Technical Field

[0001] This utility model relates to the field of liquid rubber processing technology, specifically to a positive pressure filtration device for liquid rubber plasticizers. Background Technology

[0002] In the production of liquid rubber, the use of plasticizers is an important step in improving the flexibility and plasticity of rubber. During storage and transportation, plasticizers may be mixed with impurities. If they are added directly to the rubber production process, they will affect the quality of rubber products and reduce their physical properties and stability. Therefore, plasticizers need to be filtered to meet the quality requirements of production.

[0003] Existing plasticizer filtration devices typically use multiple bolts for fixing, which is cumbersome to operate, requires significant time and manpower, hinders production efficiency, and is difficult to meet the needs of large-scale production. Furthermore, repeated disassembly and reassembly of the bolts can easily lead to stripping or damage, thus affecting the service life of the entire filtration device. Therefore, we propose a positive pressure filtration device for liquid rubber plasticizers. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6A positive pressure filtration device for liquid rubber plasticizer includes a cylinder body 1, an inlet 2 fixedly connected to the upper surface of the cylinder body 1, an air pipe 3 fixedly connected to the upper surface of the cylinder body 1, a pressure gauge 4 fixedly connected to the upper surface of the air pipe 3, a connecting plate 5 fixedly connected to the outer surface of the cylinder body 1, a support foot 6 bolted to the lower surface of the connecting plate 5, and a filtration mechanism 7 provided on the lower surface of the cylinder body 1; the filtration mechanism 7 includes a lifting device, a filtration device, and a locking device.

[0027] In this embodiment, the lifting device includes a support block 701. The support block 701 is fixedly connected to the outer surface of the cylinder 1. A cylinder 702 is fixedly connected to the upper surface of the support block 701. A connecting rod 703 is fixedly connected to one end surface of the cylinder 702. A limiting block 704 is fixedly connected to one side surface of the connecting rod 703. A limiting plate 705 is slidably connected to the outer surface of the limiting block 704. A moving groove 706 is formed on the inner surface of the limiting plate 705. A limiting groove 707 is formed on the inner surface of the moving groove 706. A base plate 708 is fixedly connected to one end surface of the connecting rod 703. A cylinder 702 is fixedly connected to the upper surface of the base plate 708. The bottom of the cylinder 709, the limiting plate 705 and the support block 701 are fixedly connected. The cylinder 702 is started, and the cylinder 702 pushes the connecting rod 703 to move. The connecting rod 703 drives the bottom plate 708 and the bottom of the cylinder 709 to move. During this process, the limiting block 704 slides along the moving groove 706 of the limiting plate 705 and slides in the limiting groove 707. Through the extension and retraction movement of the cylinder 702, under the combined action of the limiting plate 705, the limiting block 704, the moving groove 706 and the limiting groove 707, the bottom of the cylinder 709 can rise and fall stably below the cylinder body 1, thereby meeting the different needs in the filtration process of liquid rubber plasticizer.

[0028] Furthermore, the filtration device includes a discharge port 710, which is fixedly connected to the lower surface of the cylinder bottom 709. An installation groove 711 is formed on the inner surface of the cylinder bottom 709, and a support plate 712 is slidably connected to the inner surface of the installation groove 711. Filter holes 713 are formed on the upper surface of the support plate 712, and support strips 714 are fixedly connected to the upper surface of the support plate 712. Liquid rubber plasticizer enters the cylinder body 1 through the inlet 2 and, under the action of gravity and pressure, gradually flows towards the support plate 712 area above the cylinder bottom 709. The liquid rubber plasticizer first contacts the filter paper placed above the support plate 712. The support strips 714 are evenly distributed on the upper surface of the support plate 712, providing support for the filter paper and keeping it flat. The filter holes 713 above the support plate 712 assist in filtration and guide the flow of the liquid rubber plasticizer during the filtration process. After filtration, the rubber plasticizer flows out from the discharge port 710.

[0029] Furthermore, the locking device includes a first connecting block 715, which is fixedly connected to the outer surface of the cylinder 1. A connecting post 716 is rotatably connected to the inner surface of the first connecting block 715. A rotating knob 717 is fixedly connected to one end of the connecting post 716. An opening stop 718 and a locking stop 719 are fixedly connected to the upper surface of the first connecting block 715. A locking block 720 is fixedly connected to the other end of the connecting post 716. A second connecting block 721 is slidably connected to the outer surface of the locking block 720. A sliding groove 722 is formed on the upper surface of the second connecting block 721, and a locking groove 723 is formed on the inner surface of the sliding groove 722. The second connecting block 721 and the cylinder 1 are connected in series. The bottom 709 is fixedly connected, the locking block 720 is slidably connected to the sliding groove 722, and the locking block 720 is slidably connected to the locking groove 723. Rotating the rotary knob 717 to engage with the opening stop 718 causes the connecting column 716 to rotate around the first connecting block 715. When the locking block 720 slides to the position corresponding to the sliding groove 722, the bottom 709 can move freely under the action of the lifting device. When the bottom 709 moves, the locking block 720 slides in the sliding groove 722. As the bottom 709 moves to engage with the cylinder body 1, the locking block 720 moves into the locking groove 723. Rotating the rotary knob 717 to engage with the locking stop 719 causes the locking block 720 to be locked in the locking groove 723, thus achieving the fixed locking of the bottom 709 on the cylinder body 1.

[0030] In addition, two sets of connecting rods 703 are symmetrically arranged around the central axis of the base plate 708, and two sets of limiting blocks 704 are symmetrically arranged around the central axis of the connecting rods 703. Through the arrangement of the connecting rods 703, the two sets of connecting rods 703 can transmit force simultaneously and evenly during use, avoiding tilting or offset caused by excessive force on one side, so that the force on the entire lifting device is more uniform during the movement.

[0031] In addition, the inner dimensions of the mounting groove 711 match the outer dimensions of the support plate 712, and multiple sets of filter holes 713 are equally spaced on the surface of the support plate 712. Through the arrangement of the mounting groove 711 and the support plate 712, the tight fit between the mounting groove 711 and the support plate 712 during use can prevent the support plate 712 from shaking, shifting or falling off inside the filter device, making the filter device more stable and reliable.

[0032] It is worth noting that the first connecting block 715 and the second connecting block 721 are distributed in parallel. The outer dimension of the locking block 720 matches the inner dimension of the sliding groove 722. With the setting of the locking block 720 and the sliding groove 722, when in use, the outer dimension of the locking block 720 matches the inner dimension of the sliding groove 722, so that the locking block 720 can slide smoothly in the sliding groove 722. When the bottom of the cylinder 709 moves to the appropriate position, the locking block 720 can accurately enter the locking groove 723, so as to achieve precise fixation of the bottom of the cylinder 709 on the cylinder body 1.

[0033] In use, cylinder 702 is activated, pushing connecting rod 703 to move. Connecting rod 703 drives base plate 708 and cylinder bottom 709 to move. During this process, limiting block 704 slides along the moving groove 706 of limiting plate 705 and slides within limiting groove 707. Through the extension and retraction of cylinder 702, under the combined action of limiting plate 705, limiting block 704, moving groove 706, and limiting groove 707, cylinder bottom 709 is stably raised and lowered below cylinder body 1, thus meeting different requirements in the filtration process of liquid rubber plasticizer. Liquid rubber plasticizer enters the interior of cylinder body 1 through inlet 2 and gradually flows towards the support plate 712 area above cylinder bottom 709 under the action of gravity and pressure. Liquid rubber plasticizer first contacts the filter paper placed above support plate 712. Support strips 714 are evenly distributed on the upper surface of support plate 712. The filter paper is supported and kept flat. The filter holes 713 above the support plate 712 play a role in assisting filtration and guiding the flow of liquid rubber plasticizer during the filtration process. After filtration, the rubber plasticizer flows out from the outlet 710. Turning the rotary knob 717 to engage the opening stop 718 drives the connecting column 716 to rotate around the first connecting block 715. When the locking block 720 slides to the position corresponding to the sliding groove 722, the bottom of the cylinder 709 can move freely under the action of the lifting device. When the bottom of the cylinder 709 moves, the locking block 720 slides in the sliding groove 722. As the bottom of the cylinder 709 moves to engage with the cylinder body 1, the locking block 720 moves into the locking groove 723. Turning the rotary knob 717 to engage the locking stop 719 makes the locking block 720 lock in the locking groove 723, thus fixing and locking the bottom of the cylinder 709 on the cylinder body 1.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
