[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a technical solution: a plate-and-frame diatomaceous earth filter, comprising a filter box 1, a mixing box 2 and a stirring box 3, the outer side of the filter box 1 is connected to the mixing box 2, the top of the mixing box 2 is connected to the stirring box 3, a plurality of filter plate grooves 14 are provided on the top of the filter box 1, a filter plate 12 is slidably connected inside the plurality of filter plate grooves 14, the plurality of filter plates 12 are placed on an internal filter frame 18, both sides of the filter frame 18 are respectively threadedly connected to a screw rod 17, a second bevel gear 21 is coaxially mounted on the screw rod 17, and the second bevel gear 21 is meshedly connected to the first bevel gear 20.

[0025] In the present embodiment, the first bevel gear 20 is meshedly connected with the second bevel gear 21, and the screw rod 17 is accurately rotated by rotating the transmission rod 16. Since the screw rod 17 and the filter frame 18 are threadedly connected, the rotation of the screw rod 17 can smoothly and accurately drive the filter frame 18 to rise. This design not only realizes the smooth lifting and lowering of the filter frame 18, but also enables the filter plate 12 to move upward with the filter frame 18, which greatly simplifies the operating procedures for the staff to replace and install the filter plate 12, and significantly reduces the plate replacement time, thereby improving the operating efficiency and operating benefits of the entire filtration system.

[0026] The first bevel gear 20 is coaxially mounted on the transmission rod 16 . One end of the transmission rod 16 away from the first bevel gear 20 extends outward from the filter box 1 , and the end is connected to the turntable 10 . A handle 11 is provided on the side of the turntable 10 away from the transmission rod 16 .

[0027] In this embodiment, the design of the handle 11 and the turntable 10 makes it more convenient and labor-saving to rotate the transmission rod 16.
