[0056] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0057] This utility model embodiment provides a plate-pulling device for a filter press, used to pull apart the filter plates one by one after the filter press has completed the filtration operation. Figures 1 to 14 As shown, the filter press plate pulling device includes a main body 1 and insertion components. Multiple sets of insertion components are disposed on the main body 1, and all insertion components are spaced apart along the length of the main body 1. The insertion components are used to insert into the filter plates of the filter press. Since multiple sets of insertion components are provided in this embodiment, the filter press plate pulling device can pull multiple filter plates at once. Specifically, the insertion components include a rotary drive 2, a swing arm 3, and an insertion plate 4. The insertion plate 4 can insert into the filter plates and is slidably disposed on the main body 1, thereby allowing the insertion plate 4 to connect or separate from the filter plates. The swing arm 3 is rotatably mounted on the main body 1 of the equipment, and one end is connected to the insert plate 4. The rotary drive 2 is connected to the swing arm 3 and is used to drive the swing arm 3 to rotate. When the rotary drive 2 drives the swing arm 3 to rotate, the end of the swing arm 3 connected to the insert plate 4 can swing, thereby driving the insert plate 4 to slide vertically on the main body 1 of the equipment, so that the insert plate 4 can be inserted into or separated from the filter plate.

[0058] The filter press insert plate 4 device provided in this embodiment drives the insert plate 4 to slide on the main body 1 of the equipment through the cooperation of the rotary drive component 2 and the swing arm 3. Its structure is simple and highly reliable. At the same time, since there are multiple sets of insertion components, the above-mentioned filter press insert plate 4 device can be inserted into multiple filter plates in sequence, thereby enabling multiple filter plates to be pulled at one time, which has higher production efficiency compared with the prior art.

[0059] In an optional embodiment, one end of the swing arm 3 has an elongated sliding hole 321; a connecting pin is provided inside the sliding hole 321, which can slide along the extension direction of the sliding, and the connecting pin is also connected to the insert plate 4. Since the connecting pin can slide inside the sliding hole, when the rotary drive 2 drives the swing arm 3 to rotate, the connecting pin moves with the swing arm 3 and slides inside the sliding hole 321, so that the insert plate 4 can only move in a single direction on the main body 1, which has high reliability.

[0060] In other embodiments, the aforementioned sliding hole 321 can also be formed on the insert plate 4, which can also achieve the purpose of the insert plate 4 being able to move only in a single direction on the device body 1 in this embodiment.

[0061] In an optional embodiment, the swing arm 3 includes a first arm body 31 and a second arm body 32; one end of the first arm body 31 is connected to one end of the second arm body 32, and there is an included angle α between the first arm body 31 and the second arm body 32, where α is greater than 0° and less than 180°; preferably, the first arm body 31 and the second arm body 32 are arranged perpendicularly, that is, the swing arm 3 has an L-shaped structure, and α equals 90°; the aforementioned rotary drive component 2 is a telescopic cylinder, such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder; the telescopic cylinder has a fixed end and a telescopic end; the fixed end of the telescopic cylinder is rotatably mounted on the main body 1 of the equipment, and the telescopic end is rotatably connected to the first arm body 31. In use, the telescopic end is extended or retracted by the fixed end, thereby driving the swing arm 3 to rotate. By setting the swing arm 3 with the above structure, the overall height of the filter press insert plate 4 device can be reduced, thus facilitating its cooperation with the filter press.

[0062] Initially, when the insert plate 4 is not inserted into the filter plate, the connecting pin is located at the end of the sliding hole 321 away from the first arm body 31. When the insert plate 4 needs to be inserted into the filter plate, the rotary drive 2 drives the swing arm 3 to rotate. Under the restriction of the slide rail 5, the connecting pin slides in the sliding hole 321 towards the end closer to the first arm body 31, thereby ensuring that the insert plate 4 can only slide in the vertical direction.

[0063] In other embodiments, the swing arm 3 can also be a straight rod, and the rotary drive 2 can be an electric motor or a hydraulic motor, etc.

[0064] In an optional embodiment, the device body 1 includes a first main board 11 and a second main board 12, both elongated in shape; the first main board 11 and the second main board 12 are arranged opposite to each other; the device body 1 also includes a plurality of connecting plates 13, the two ends of which are fixedly connected to the first main board 11 and the second main board 12 respectively, and all connecting plates 13 are spaced apart along the length direction of the first main board 11 and the second main board 12; the connecting plates 13 also correspond one-to-one with plug-in components, and the rotation drive 2 of the plug-in component is disposed on the corresponding connecting plate 13. In this embodiment, the connecting plate 13 can not only be used to connect the first main board 11 and the second main board 12, but also serve as a support for the rotation drive 2, thus having multiple functions. As mentioned above, the rotation drive 2 is a telescopic cylinder; therefore, in this embodiment, the fixed end of the telescopic cylinder is rotatably disposed on the corresponding connecting plate 13. Specifically, in this embodiment, a rotating seat 7 is provided on the connecting plate 13, and the fixed end of the telescopic cylinder is rotatably disposed on the rotating seat 7.

[0065] In an optional embodiment, a plurality of ridges 14 are provided below both the first main plate 11 and the second main plate 12; the ridges 14 on the first main plate 11 and the ridges 14 on the second main plate 12 are arranged in a one-to-one correspondence, and the corresponding two ridges 14 are arranged opposite each other; each ridge 14 is rotatably provided with at least one roller 15 to facilitate the movement of the plate pulling device of the filter press. It should be noted that when multiple rollers 15 are rotatably provided on the ridge 14, in order to maintain balance, the number of rollers 15 on the corresponding two ridges 14 is the same and they are arranged opposite each other.

[0066] In an optional embodiment, in order to ensure the stability of the insert plate 4 when sliding, preferably, in this embodiment, the insertion assembly further includes a slide rail 5; the slide rail 5 is fixedly disposed on the main body 1 of the device, and the insert plate 4 is slidably installed in the slide rail 5.

[0067] Specifically, in this embodiment, the slide 5 includes a first slide plate 51, a second slide plate 52, a third slide plate 53, and a second mounting plate 55. One end of the first slide plate 51 and one end of the second slide plate 52 are fixedly disposed at both ends of the third slide plate 53 to form a U-shaped structure. The insert plate 4 is slidably disposed in the area between the first slide plate 51, the second slide plate 52, and the third slide plate 53. A first mounting plate 54 is fixedly disposed above the first slide plate 51, and a second mounting plate 55 is fixedly disposed above the second slide plate 52. The slide 5 is fixedly disposed on the equipment body 1 through the first mounting plate 54 and the second mounting plate 55.

[0068] Optionally, in this embodiment, the first mounting plate 54 is fixedly mounted on the first main board 11, and the second mounting plate 55 is fixedly mounted on the second main board 12. A first support groove 111 is formed on the first main board 11, and a first support plate 112 is fixedly mounted within the first support groove 111. A second support groove is formed on the second main board 12, and a second support plate 122 is fixedly mounted within the second support groove. The first mounting plate 54 is fixedly connected to the first support plate 112, and the second mounting plate 55 is fixedly connected to the second support plate 122. By providing the first support groove 111, the second support groove, the first support plate 112, and the second support plate 122 to support the slide rail 5, the stability of the slide rail 5 can be improved.

[0069] In an optional embodiment, the aforementioned swing arm 3 is rotatably mounted on the slide rail 5, thereby improving the overall integrity of the device. Specifically, in this embodiment, the first slide rail 51 and the second slide rail 52 are provided with corresponding pin holes, and the swing arm 3 is rotatably connected to the two pin holes via a pin shaft. Further, in this embodiment, the end of the first slide rail 51 opposite to the third slide rail 53 and the end of the second slide rail 52 opposite to the third slide rail 53 are provided with corresponding protrusions 56, and the pin holes are disposed within the protrusions 56.

[0070] In an optional embodiment, the aforementioned plug-in assembly further includes a proximity switch for detecting the position of the filter plate. When the plug-in assembly is positioned above the filter plate, the rotary drive 2 drives the swing arm 3 to rotate, thereby causing the plug plate 4 connected to the swing arm 3 to slide, connecting the plug plate 4 to the filter plate. The plug plate 4 has an installation channel 41, and the proximity switch is fixedly installed within the installation channel 41, thereby improving the detection accuracy of the proximity switch and preventing false triggering of the rotary drive 2.

[0071] Preferably, in this embodiment, the plug-in assembly further includes a mounting bracket 6 for mounting the aforementioned proximity switch. The mounting bracket 6 has an S-shaped structure and includes a first plate 61, a second plate 62, and a third plate 63. The first plate 61 and the second plate 62 are respectively fixedly disposed at both ends of the third plate 63 and located on opposite sides of the third plate 63. The first plate 61 is connected to the device body 1, specifically to the slide rail 5; the end of the first plate 61 furthest from the third plate 63 is fixed to the upper end of the third slide rail 53. The third plate 63 and the second plate 62 extend into the mounting channel 41, and the proximity switch is mounted on the second plate 62. Because the proximity switch is fixedly mounted on the slide rail 5, the proximity switch will not move with the plug-in plate 4, thereby improving the detection accuracy of the proximity switch.

[0072] Preferably, in this embodiment, in order to avoid interference between the swing arm 3 and the mounting bracket 6, the plug-in assembly includes two swing arms 3, which are spaced apart and located on both sides of the mounting bracket 6, thereby avoiding interference with the mounting bracket 6 while improving the stability of the plug plate 4.

[0073] In an optional embodiment, the aforementioned insert plate 4 includes a first insert plate body 42, a second insert plate body 43, and a third insert plate body 44. The first insert plate body 42 and the second insert plate body 43 are respectively fixedly disposed on both sides of the third insert plate body 44, making the insert plate 4 U-shaped. The aforementioned mounting channel 41 is formed between the first insert plate body 42, the second insert plate body 43, and the third insert plate body 44. A first insertion portion extends downward from the bottom of the first insert plate body 42, and a second insertion portion 431 extends downward from the bottom of the second insert plate body 43. A first slot for insertion into a filter plate is formed between the first insertion portion and the third insert plate body 44, and a second slot for insertion into a filter plate is formed between the second insertion portion 431 and the third insert plate body 44. The insert plate 4 is inserted into the filter plate through the first slot and the second slot. The two ends of the connecting pin are respectively connected to the first insert plate body 42 and the second insert plate body 43.

[0074] Optionally, in this embodiment, three sets of the aforementioned plug-in components are provided, thus enabling the simultaneous pulling of three filter plates. During use, the filter press plate-pulling device, driven by external power and in conjunction with a proximity switch, reaches the support position above the three filter plates. The three rotating drive components 2 operate synchronously to connect the plug plate 4 with the corresponding filter plate. Specifically, the first plug-in part and the second plug-in part 431 are inserted into the plug holes of the filter plate and fixed by the cooperation of the first slot and the second slot. Afterward, the filter press plate-pulling device, driven by external power, pulls the three filter plates to the designated position. The rotating drive component 2 at the end opposite to the external drive first operates to separate the plug plate 4 from the filter plate. Then, the filter press plate-pulling device, driven by external power, continues to pull the remaining two filter plates and places the two filter plates in the designated position in sequence. The above actions are repeated continuously until all filter plates are processed.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
