[0002] Belt filter presses are highly efficient, continuous solid-liquid separation devices widely used in wastewater treatment, mining, food processing, and many other industries. Their core working principle involves creating a pressure gradient under the tension of the filter belt, gradually squeezing the sludge and achieving sludge-water separation.

[0003] However, the positions of the lower filter belt assembly and the upper pressure belt assembly in existing belt filter presses are fixed. This results in the fixed positions of the filter belt body and the pressure belt body, which in turn fixes the pressure on the material between the filter belt body and the pressure belt body, making it impossible to adjust the pressure on the material.

[0013] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0014] like Figures 1-3 As shown, this utility model discloses a stepped ultra-high pressure filter press with adjustable working pressure, including a frame 1, a lower filter belt assembly 2, an adjustable pressure upper pressure belt assembly 3, and a fixing frame 4. The lower filter belt assembly 2 is rotatably mounted on the frame 1 for filtering materials; The mounting bracket 4 is fixed to the top of the frame 1 and is used to install the upper pressure belt assembly 3; The upper pressure belt assembly 3 is rotatably mounted on the fixed frame 4. The upper pressure belt assembly 3 is located above the lower filter belt assembly 2 and is used to press down the material.

[0015] Furthermore, the lower filter belt assembly 2 includes a first drive roller 21, a first pressure roller 22, and a filter belt body 23; The first drive roller 21 provides power to the filter belt body 23. Multiple first drive rollers 21 are rotatably connected to the frame 1, and their specific installation positions can be selected according to actual needs; this application does not impose any restrictions. A first motor is coaxially and fixedly connected to each first drive roller 21, and the first motor is fixedly connected to the frame 1.

[0016] Multiple first pressure rollers 22 are disposed on the top of the frame 1, and the first pressure rollers 22 are rotatably connected to the frame 1; The filter belt body 23 is fitted over the first drive roller 21 and the first pressure roller 22.

[0017] Furthermore, the fixing frame 4 is fixed with a plurality of equally spaced vertical plates 41, and the vertical plates 41 are provided with vertically extending through slots 42.

[0018] Furthermore, the upper pressure belt assembly 3 includes a second drive roller 31, a second pressure roller 32, a lifting mechanism 33, and a pressure belt body 34; Multiple second drive rollers 31 are rotatably connected to the fixed frame 4, and a second motor is coaxially fixedly connected to each second drive roller 31. The second motor is fixedly connected to the fixed frame 4. The end of the second pressure roller 32 is vertically inserted into the through groove 42, and both ends of the second pressure roller 32 are fixed with connecting blocks 321. The lifting mechanism 33 is threadedly connected to the connecting block 321; The pressure belt body 34 is sleeved outside the second drive roller 31 and the second pressure roller 32.

[0019] Furthermore, the lifting mechanism 33 includes a third motor 331, a rotating shaft 332, a first bevel gear 333, a second bevel gear 334, and a lead screw 335; The third motor 331 is fixedly connected to the fixed frame 4 via the motor frame; The rotating shaft 332 is coaxially and fixedly connected to the output shaft of the third motor 331, and the two ends of the rotating shaft 332 are respectively coaxially and fixedly connected to the first bevel gear 333 facing the same direction; The second bevel gear 334 is located below the first bevel gear 333, and the second bevel gear 334 is meshed with the first bevel gear 333. The lead screw 335 extends vertically and is coaxially and fixedly connected to the second bevel gear 334. The lead screw 335 is rotatably connected to the frame 1 through a bearing, and a connecting block 321 is threaded onto the lead screw 335.

[0020] The lifting mechanism 33 operates as follows: the third motor 331 starts, driving the rotating shaft 332 to rotate. The rotating shaft 332 drives the first bevel gear 333 to rotate, and the first bevel gear 333 drives the second bevel gear 334 to rotate, which in turn drives the lead screw 335 to rotate. This allows the connecting block 321 to slide up and down along the lead screw 335, thereby adjusting the height of the second pressure roller 32.

[0021] When pressure needs to be adjusted, Figure 1 For example, adjusting the lifting mechanism 33 on the left and the middle moves the second pressure roller 32 on the left and the second pressure roller 32 in the middle downwards, thereby reducing the gap between the pressure belt body 34 and the filter belt body 23 and increasing the pressure on the material between them. Simultaneously, the lifting mechanism 33 on the right can be adjusted to raise the second pressure roller 32 on the right appropriately, thereby reducing the tension on the pressure belt body 34 and preventing it from breaking. Clearly, to increase the pressure, the tension on the pressure belt body 34 after adjustment should be greater than before adjustment.

[0022] It is understandable that the position of the second pressure roller 32 can be adjusted according to actual working conditions, and this application will not go into detail about its specific downward adjustment height.

[0023] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
