[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0026] like Figure 1-5 As shown, the filter cloth deviation correction device of the embodiment of the utility model comprises: an adjustment frame 1, a deviation corrector 2 and a probe rod 3.
[0027] The adjustment frame 1 includes a first rod 11, a second rod 12 and a connecting block 13. The connecting block 13 is provided with a first hole 131 and a second hole 132. The axis of the first hole 131 is perpendicular to the axis of the second hole 132. The outer periphery of the first rod 11 is slidably fitted in the first hole 131, and the outer periphery of the second rod 12 is slidably fitted in the second hole 132.
[0028] Specifically, the first hole 131 extends in the vertical direction, and the second hole 132 extends in the horizontal direction. The second rod 12 can not only move in the vertical direction relative to the first rod 11, but also move in the horizontal direction relative to the first rod 11. The above arrangement enables the installer to conveniently adjust the position of the deviation corrector and the probe rod according to the position of the filter cloth, so that the probe rod is in full contact with the filter cloth to achieve a better detection and correction effect.
[0029] The deviation corrector 2 is arranged on the second rod 12, and the deviation corrector 2 is used to connect the deviation correcting airbag; the probe rod 3 is connected to the deviation corrector 2, the probe rod 3 can swing under the push of the filter cloth 5, and the probe rod 3 has a normal position during the swinging process, and the deviation corrector 2 is used to control the action of the deviation correcting airbag when the probe rod 3 swings away from the normal position to correct the filter cloth 5.
[0030] Specifically, two deviation-correcting airbags are generally provided, and the two deviation-correcting airbags are respectively located on both sides of the filter cloth 5 roller. The position of the filter cloth 5 roller can be adjusted by inflating or deflating the two deviation-correcting airbags, thereby adjusting the position of the filter cloth 5. The deviation corrector 2 can be connected to the air source distribution valve of the deviation-correcting airbag, and the inflation or deflation of the deviation-correcting airbag can be controlled according to the direction and angle of the probe rod 3 deviating from the normal position.
[0031] In the filter cloth deviation correction device of the utility model embodiment, the deviation corrector is arranged on the second rod, and the connection block is arranged so that the second rod can move relative to the first rod, so that the position of the deviation corrector and the probe rod can be adjusted according to the position of the filter cloth, and the use is more convenient. The contact area between the probe rod and the filter cloth is small, and the problem of slurry accumulation is not easy to occur. The probe rod is more sensitive to the deviation of the filter cloth, and has the advantage of better deviation correction effect.
[0032] In some embodiments, Figure 2-5 As shown, the filter cloth correction device includes a first adjusting member and a second adjusting member (not shown in the figure), the connecting block 13 is provided with a first adjusting hole 133 and a second adjusting hole 134, the first adjusting hole 133 and the second adjusting hole 134 are respectively connected to the first hole 131 and the second hole 132, the first adjusting member and the second adjusting member are respectively engaged in the first adjusting hole 133 and the second adjusting hole 134, and the first adjusting member and the second adjusting member are respectively used to resist the first rod 11 and the second rod 12 to achieve the relative position fixation between the first rod 11 and the second rod 12.
[0033] Specifically, the first adjusting member is first moved so that the first adjusting member does not contact the first rod 11, and the position of the second rod 12 in the vertical direction can be adjusted. After the position adjustment is completed, the first adjusting member is moved again to stop against the first rod 11, and the position of the second rod 12 in the vertical direction can be fixed. The second adjusting member is used in the same way as the first adjusting member, and is used to adjust the position of the second rod 12 in the horizontal direction. The above arrangement facilitates the adjustment of the position of the deviation corrector 2 and the probe rod 3.
[0034] In some embodiments, Figure 2-5 As shown, the first adjusting member is threadedly engaged in the first adjusting hole 133, and the second adjusting member is threadedly engaged in the second adjusting hole 134. Specifically, the first adjusting member and the second adjusting member are both top screws. The threaded connection method is more convenient to use.
[0035] In some embodiments, Figure 1 As shown, the probe rod 3 includes a contact section 31, and the contact section 31 is used to contact the filter cloth 5. The contact section 31 is provided to facilitate the installer to adjust the position of the probe rod 3 according to the relative position of the filter cloth 5 and the contact section 31. The contact section 31 can be made of a more wear-resistant material to improve the correction accuracy for long-term use.
[0036] In some embodiments, Figure 1 As shown, the probe rod 3 includes a counterweight section 32, and the counterweight section 32 is located on the side of the contact section 31 away from the deviation corrector 2. The counterweight section 32 is arranged so that the probe rod 3 can sag naturally and swing under the pushing action of the filter cloth 5.
[0037] In some embodiments, Figure 1As shown, the filter cloth deviation correction device includes a fixing member 4, which is fixedly connected to the first rod 11, and the fixing member 4 is used to fix the adjustment frame 1. Specifically, the fixing member 4 can be a fixing plate, and a plurality of fixing holes are provided on the fixing plate, and the fixing holes are used to fix the fixing plate. Specifically, the fixing plate can be fixed to the frame of the dehydrator by fasteners such as screws, thereby achieving fixed installation of the adjustment frame 1.
[0038] In some embodiments, Figure 1 , 2 As shown, the first rod 11 and the second rod 12 are both round rods. The round outer circumference allows the first rod 11 and the second rod 12 to rotate freely relative to the connecting block 13, and the deviation corrector 2 and the probe rod 3 can be tilted at a certain angle, making position adjustment more convenient and suitable for various installation conditions.
