The transmission roller 10 transmits power, thereby driving the lower right sprocket 7 to rotate, and the right chain 9 and the upper right sprocket 8 rotate accordingly. The left chain 6 and the right chain 9 move up and down, thereby tightening and relaxing the filter cloth 21, preventing the filter cloth 21 from being overly stretched or relaxed, improving the operating stability, and solving the problems of low safety and high maintenance costs.
[0025] like Figure 1-3 As shown, in some embodiments, the tensioning bracket 1 includes a left support plate 101 and a right support plate 102 that are spaced apart, and a plurality of connecting plates 103 that are arranged between the left support plate 101 and the right support plate 102. The left movable groove 1011 is arranged on the left support plate 101, and the right movable groove 1021 is arranged on the right support plate 102. The left support plate 101, the right support plate 102 and the connecting plate 103 constitute a frame structure with a simple structure, open space and light weight.
[0026] like Figure 1-3 As shown, in some embodiments, the support assembly includes a left support plate 14 and a right support plate 15 symmetrically arranged on the upper part of the tensioning bracket 1, and two support rollers 16 symmetrically arranged on the left support plate 14 and the right support plate 15, and the support rollers 16 are rotatably connected to the left support plate 14 and the right support plate 15. The two support rollers 16 can support the filter cloth 21, and cooperate with the tensioning roller 2, and the filter cloth 21 is concave.

The filter cloth 21 is concave after passing through the supporting roller 16 and the tensioning roller 2, and the hydraulic motor rotates clockwise to drive the coupling 13 and the transmission roller 10. The lower left sprocket 4 and the lower right sprocket 7 also rotate clockwise and run downward synchronously through the left chain 6 and the right chain 9. The tensioning roller 2 moves downward through the left connecting frame 11 and the right connecting frame 12 to stretch the filter cloth 21 downward to make it tight, and then the filter cloth 21 is driven to rotate by the filter press. When the vertical filter press is finished unloading and the plate layer needs to be closed, the hydraulic motor rotates counterclockwise, the same as the previous transmission mode, the tensioning roller 2 moves upward and contacts the upper sensor 18 and then stops, so that the filter cloth 21 is relaxed and free from force, ensuring that the filter cloth 21 will not be torn when the plate layer is pressed down. When the lower sensor 20 receives the signal, an alarm is issued, and it can be judged that the filter cloth 21 has been broken at this time and the machine should be stopped immediately.
[0033] The above embodiments are merely descriptions for clearly illustrating the present invention, and are not limitations on the implementation methods.
