When the filter plate is opened, the circulating chain rotates to drag the female hook 21 to horizontally displace, the female hook group 21 of the dragging side chain 166 displaces towards the power plate 3, the female hook group 21 of the returning side chain 165 displaces towards the tail plate 2, when the female hook 21 enters the dragging side chain 166 around the driven chain wheel 116, the female hook slides on the wing plate sliding surface 53 above each sub-hook group 23, when the female hook slides to the opening filter plate 124, because the opening filter plate 124 is not supported by the sub-hook seat 51 on the power plate 3 side, the female hook 21 rotates downwards by self weight to fall into the sub-hook wing plate front inclined hook 167 of the sub-hook group 23 of the opening filter plate 124, the female hook tooth 68 hooks the sub-hook front inclined surface 49 and the dragging sub-hook 46 displaces towards the power plate, the sub-hook 46 rotates upwards around the positioning rotating shaft 66 by the pulling force, the sub-hook 47 disengages from the sub-hook seat positioning vertical surface 57 of the sub-hook group 23 of the non-hook group of the opening filter plate, and the sub-hook 47 rises to the front inclined surface 49 and stops coinciding with the sub-hook seat 54, at this time, the female hook tooth 68 hooks the sub-hook seat wing plate forward inclined plane 54, the sub-hook seat 51 bears the horizontal dragging force of the female hook tooth 68, no relative displacement exists between the two, the start-up hook filter plate 124 is dragged by the female hook 21 to become a sliding slide filter plate 125, when the slide filter plate 125 is displaced to the opened filter plate, the sub-hook beak 47 of the opened filter plate group 5 firstly abuts against the female hook bottom guide concave surface 73 of the female hook, because an inclined plane of the top surface of the sub-hook beak 47 inclines upwards towards the power plate 3 side, the female hook 21 rotates upwards gradually due to the abutment of the sub-hook beak 47, so that the escapement pressure point 131 of the female hook tooth 68 contacting with the sub-hook seat wing plate forward inclined plane 54 is displaced upwards gradually, when the slide filter plate 125 is displaced towards the power plate 3, the mouth of the sub-hook beak 47 of the opened filter plate is guided by the sub-hook seat guide inclined plane 56 of the slide filter plate 125 to rotate upwards, and the slide filter plate 125 is displaced to the apex of the sub-hook seat guide inclined plane 56, the sub-hook beak 47 of the opened filter plate falls into the sub-hook seat positioning vertical surface 57 of the sliding filter plate 125 by self-weight and hooks the sub-hook seat positioning vertical surface without separation; when the sliding filter plate 125 continuously moves towards the power plate 3, the bottom sliding surface 67 of the female hook 21 touches the wing plate sliding surface 53 of the opened unhooked filter plate 126, along with the movement of the female hook 21 towards the power plate 3, the female hook 21 is pushed upwards to enable the escapement pressure point 131, which is in contact with the front inclined surface 54 of the female hook tooth 68 and the front inclined surface 54 of the sub-hook seat, to continuously move upwards, when the escapement pressure point 131 moves upwards to the unhooking arc surface 55 of the sub-hook seat, the female hook tooth 68 cannot hook the sub-hook seat 51, the female hook tooth 68 slides to the top surface of the sub-hook seat 51 along the guidance of the arc surface, the sliding filter plate 125 stops moving, the sliding filter plate 125 is attached to the opened unhooked filter plate 126, and the beak of the sub-hook 47 of the opened filter plate is clamped into the positioning vertical surface 57 of the sub-; because the sliding friction between the female hook bottom sliding surface 67 and the wing plate sliding surface 53 needs to be properly lubricated, the female hook moves to the female hook oil smearing device 24 after leaving the power plate 3, the female hook bottom sliding surface 67 leans against the oil smearing wheel 169, the female hook 21 presses the oil smearing wheel 169 by self weight, the oil smearing wheel 169 drags the oil smearing wheel 169 to rotate synchronously by virtue of the friction force between the female hook bottom sliding surface 67 and the wing plate sliding surface 169, the lubricating oil 164 in the female hook oil smearing device 24 is smeared by the oil smearing wheel 169 and is attached to the female hook bottom sliding surface 67, when the female hook 21 passes through the oil wiping wheel 169, the female hook is fully stained with the lubricating oil 164, in order to avoid being stained with excessive lubricating oil, therefore, the female hook 21 passes through the oil wiping wheel 169 and then scrapes the excessive lubricating oil 164 to a proper thickness by the scraper 101, the female hook 21 bypasses the driving shaft 112 and then moves to the return side chain 165 to move to the driven shaft, and each female hook 21 continuously operates in this way, and the filter plate opening operation program is continuously performed through the procedures of hook sliding, hook opening, hook releasing, oil wiping and the like.
When the filter press is used for filtering, the raw material 159 injected into the filter chambers 158 and flowing in the mud pipe 139 has a slight pressure difference in each filter chamber 158 due to the viscosity of the fluid and the resistance of the pipeline, the pressure difference is proportional to the flow rate of the raw material 159 in the mud pipe 139 and the concentration of the raw material 159, the phenomenon that the pressure in each filter chamber 158 is unequal in a single closed filter press is called a bias phenomenon, when the bias of the filter chamber is too large, the raw material 159 on the side with larger internal pressure in the filter chamber is pressed to the filter chamber with smaller internal pressure, and the bias phenomenon causes the filter plate to be damaged when the pressure exceeds the strength of the filter plate group 5. For some materials that are easy to filter, the filtering flow rate can be increased to improve the processing efficiency, but the flow rate in the mud pipe 139 must not be increased synchronously to avoid the bias condition, so that the pipeline for the raw material 159 to enter the filtering chamber 158 is multi-point fed to maintain the constant flow rate of the raw material 159. As shown in fig. 1,2,3 and 65, the raw material is divided into 4 pipelines from the main mud inlet pipe 6, the flow rate of the raw material 159 in each pipeline is 1/4 of the output of the pumps 150 and 151, the raw material 159 is injected into the first filtering area 140 by the front mud inlet pipe 7 and the tail plate 2, is injected into the first filtering area 140 by the first middle mud inlet pipe 8 and the second filtering area 141 by the distribution plate 13, is injected into the second filtering area 141 and the third filtering area 142 by the second middle mud inlet pipe 9 and the distribution plate 13, and is injected into the third filtering area 142 by the tail mud inlet pipe 10 and the power plate 3, the raw material 159 is divided into the mud guide pipe 139 so that the horizontal flow rate is not increased due to the increase of the pumping amount of the pumps 150 and 151, thereby effectively avoiding the bias condition; the two sides of the bottom of each distributing plate 13, the power plate 3 and the tail plate 2 are respectively provided with a water collecting hole 144, the water collecting holes 144 are synchronously communicated, filtrate 143 generated by filtering operation can be quickly discharged out of the filter press through the communicating pipe, and the water collecting holes 144 are connected in series through a drain pipe 145 to form a single pipeline to flow to a clean water tank 168; as shown in FIG. 65, the pipelines connecting the first middle mud inlet pipe 8, the second middle mud inlet pipe 9 and the distributing plate 13 are provided with check valves 146, the pipelines connecting the tail mud inlet branch pipe 10 and the power plate 3 are provided with check valves 146, the valve assembly direction is such that the raw materials cannot flow out of the filter chamber, the raw materials cannot bypass the short flow from the middle mud inlet pipes 8, 9 and the tail mud inlet pipe 10 to the raw material tank 154 during the mud discharging and back blowing operation of the compressed air 157, and the residual materials in the mud guide pipe 139 can be removed reliably.
