[0002] After sludge is concentrated and digested, its water content is still extremely high. In order to recover the water in the sludge, a frame plate filter press is used to filter and dehydrate the sludge. With the pressure difference on both sides of the filter medium as the driving force, the sludge water is forced to pass through the filter medium to form filtrate, while the solid particles are intercepted on the medium to form a filter cake, so as to achieve the purpose of sludge dehydration.
[0003] The existing authorized publication number is CN216677127U3, which discloses an automatic vibrating device for a frame plate filter press, including filter plates and filter cloths, and further includes support plates and a vibration assembly. The filter plates are hollow and arranged in a ring shape. There are two support plates corresponding to the filter plates and they are slidably connected to the filter plates; the filter cloths are arranged on both sides of the filter plates, and a drainage cavity is formed between the filter cloths and the support plates. There are protrusions on the mutually remote sides of the support plates, and the protrusions can abut against the filter cloths.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0023] The technical solution provided by the present invention is as follows: As Figures 1 to 5 shown, in this embodiment, an automatic material vibrating device for a frame plate filter press includes a support bottom plate 1. The upper end of the support bottom plate 1 is fixedly connected with a support main leg 11. The upper end of the support bottom plate 1 is fixedly connected with a liquid collecting tank 12. One end of the support main leg 11 away from the support bottom plate 1 is fixedly connected with a vertical plate 13. The front surface of the inner wall of the vertical plate 13 is fixedly connected with a fixed block 14. One end of the fixed block 14 away from the vertical plate 13 is rotatably connected with a fastening screw 15. It further includes: a driving mechanism 2. The driving mechanism 2 includes a fixed plate 22 fixedly connected to the front surface of the vertical plate 13. One end of the fixed plate 22 away from the vertical plate 13 is fixedly connected with a rotating motor 21. The output end of the rotating motor 21 is rotatably connected with a rotating shaft 23. One end of the rotating shaft 23 away from the rotating motor 21 is fixedly connected with a docking rod 24. One end of the docking rod 24 away from the rotating shaft 23 is fixedly connected with a rotating gear 26. The top of the rotating gear 26 is fixedly connected with a conveyor belt 27.
[0024] The surface of the docking rod 24 is rotatably connected with a pulley 25.

By starting the electric telescopic rod 31, the rotating motor 21 located in front of the fixing plate 22 can be started at the same time. The rotating motor 21 will drive the rotating shaft 23 at its output end to rotate, thereby driving the docking rod 24 to rotate, so that the rotating gear 26 of the docking rod 24 away from the rotating shaft 23 drives the conveyor belt 27 to displace. At the same time, since the surface of the docking rod 24 is rotatably connected with a pulley 25, and the pulley 25 is arranged on the surfaces of the two docking rods 24, the pulley 25 will be driven to rotate while the docking rod 24 rotates, making the transmission of the conveyor belt 27 more convenient.
[0025] An extrusion mechanism 3 is arranged on the inner wall of the vertical plate 13. The extrusion mechanism 3 includes an electric telescopic rod 31 fixedly connected to the surface of the inner wall of the vertical plate 13. One end of the electric telescopic rod 31 away from the vertical plate 13 is fixedly connected with a push rod 38, and a limiting plate 32 is fixedly connected to the surface of the push rod 38.
[0026] A material storage box 33 is clamped to the front surface of the limiting plate 32.

[0027] The number of the clamping blocks 34 is set to several, and several clamping blocks 34 are fixedly connected to the periphery of the surface of the material storage box 33. A connecting plate 36 is fixedly connected to the right end of the limiting plate 32. One end of the connecting plate 36 away from the limiting plate 32 is fixedly connected with a docking block 37, and the lower end of the docking block 37 is fixedly connected with the upper end of the conveyor belt 27.

And since the number of the material storage boxes 33 is set to several, several material storage boxes 33 all contact the front limiting plate 32.
[0028] A vibrating mechanism 4 is arranged on the surface of the main support leg 11. The vibrating mechanism 4 includes a support plate 41 fixedly connected to the front surface of the main support leg 11. The upper end of the support plate 41 is fixedly connected with a docking plate 42, and one end of the docking plate 42 away from the support plate 41 is fixedly connected with a cylinder 43.
[0029] The upper end of the docking plate 42 is fixedly connected with a telescopic rod 44. The number of telescopic rods 44 is set to several, and several telescopic rods 44 are fixedly connected to the periphery of the upper end of the docking plate 42. The number of docking plates 42 is set to two, and the two docking plates 42 are symmetrically arranged up and down about the center of the cylinder 43.

A pressing box 46 is arranged directly above the column 45. The pressing box 46 is fixedly connected to the inner wall of the vertical plate 13. The inner wall of the pressing box 46 is fixedly connected with a pressing plate 47. Slots 48 are opened around the pressing plate 47. By closing the rotating motor 21 and the electric telescopic rod 31 and starting the cylinder 43 at the same time, the cylinder 43 will drive the telescopic rods 44 around it to perform up and down vibration displacement, so that the column 45 above the docking plate 42 contacts the lower end of the pressing box 46. Thus, when the material storage box 33 is reciprocating up and down on the column 45, it will perform the material vibrating work, thereby improving the quality of the sludge filtration and vibrating material obtained.
[0030] The utility model provides an automatic material vibrating device for a frame plate filter press, and the specific working principle is as follows:
[0031] After the frame plate filter press completes the filtration of the slurry, then the sludge is placed inside the material storage box 33. At this time, the electric telescopic rod 31 at the inner wall of the vertical plate 13 is started, so that the electric telescopic rod 31 will push the push rod 38, so that the material storage box 33 on the limiting plate 32 moves towards the pressing box 46 until the clamping block 34 contacts and is clamped with the slot 48. And because the number of material storage boxes 33 is set to several, several material storage boxes 33 all contact the limiting plate 32 in front, and the filtered liquid will fall into the liquid collecting box 12 below. When starting the electric telescopic rod 31, the rotating motor 21 located in front of the fixed plate 22 can be started at the same time. The rotating motor 21 will drive the rotating shaft 23 at its output end to rotate, thereby driving the docking rod 24 to rotate, so that the rotating gear 26 of the docking rod 24 far from the rotating shaft 23 drives the conveyor belt 27 to move. At the same time, because a pulley 25 is rotatably connected to the surface of the docking rod 24, and the pulley 25 is arranged on the surfaces of the two docking rods 24, so when the docking rod 24 rotates, it will also drive the pulley 25 to rotate, so that the conveyor belt 27 is more convenient to drive. When each limiting plate 32 contacts the material storage box 33 in front, close the rotating motor 21 and the electric telescopic rod 31 and start the cylinder 43 at the same time. The cylinder 43 will drive the telescopic rods 44 around it to perform up and down vibration displacement, so that the column 45 above the docking plate 42 contacts the lower end of the pressing box 46. Thus, when the material storage box 33 is reciprocating up and down on the column 45, it will perform the material vibrating work, thereby improving the quality of the sludge filtration and vibrating material obtained.
