Detailed Description
As shown in fig. 1, 2, 3, 4 and 5, the following technical solutions are adopted in the embodiment of the present invention: a plate-and-frame filter press comprises a filter cake groove 1, a water nozzle 2, a frame 3, a chain wheel 4, a guide rail 5, a thrust plate 6, a filter plate assembly 7, a chain 8, a pressing plate 9, a pulling plate trolley 10, a cross beam 11, a water tank 12, a hydraulic station 13, a double-row chain wheel 14, an oil cylinder 15, a hydraulic motor 16, a filter frame 17, a filter plate 18, filter cloth 19, a handle 20, a motor 21, an oil pump 22 and an oil tank 23.
The plate and frame filter press is composed of a group of filter plates 18 and a filter frame 17 which are combined to form a filter device required by filtration. In the filtering process, the filter cloth 19 needs to be added on the adjacent filter plates 18, and in order to better ensure that the filter cloth 19 is attached on the filter plates 18, the filter plates 18 are provided with bulges for supporting the filter cloth 19. A circular hole is arranged in the center of the filter plate 18 and used for introducing filter pulp; two circular holes are arranged above the filter frame 17 for introducing washing water to clean the filter cake and the filter plate 18. Handles 20 are mounted on both sides of the filter frame 17 for fixing to the cross member 11 and supporting the filter plates 18. And a filter cloth 19 is arranged between the filter plate 18 and the filter frame 17, and the filter cloth 19 mainly plays a role of a sealing gasket. The suspension enters the filter chamber from the feed opening under the pressure of the feed pump until the filter chamber is filled. The solid particles pass through the filter cloth 19 to form a filter cake, which is continuously compressed. The filtrate penetrates through the filter cloth 19 and the filter plate 18 into the filtrate chamber and flows out concentratedly at the liquid discharge port below the filter frame 17. After the filtration is finished, clean washing water can be introduced from the small hole above the thrust plate 6 to wash filter residues. After the washing is finished, if necessary, compressed air can be introduced, the residual washing liquid is removed, and the filter cake is further dried. Then the filter plates 18 are loosened under the control of the hydraulic oil cylinder 15, the chain wheel 4 is driven under the action of the hydraulic motor 16, the chain 8 mechanism is driven by the chain wheel 4 to start to operate, and the plate pulling trolley 10 starts to move back and forth on the guide rail 5, so that the filter plates 18 are pulled one by one to unload filter cakes. After the filter press has removed the filter residues, the filter cloth 19 is cleaned and the filter plates 18 are pressed again, and the next operating cycle is started.
When the filter press starts to work, the motor 21 pressurizes the oil pump 22 to drive the piston rod in the oil cylinder 15 to move forward to finish the action of pressing the filter plate 18, and when the calibrated working pressure is reached, the motor 21 is shut down. The filter press automatically enters a pressure maintaining state.
The filter device of plate and frame filter-pressing, after getting into the pressurize state, the manual work each pipeline valve switching situation of inspection hydraulic pressure station 13, confirm that there is not any problem after slowly opening the charge pump, make the thick liquid of straining get into the filter chamber through the feed port of thrust plate 6 central authorities under the pressure of charge pump, through the pressure that the charge pump was given, strain the thick liquid and constantly pressurize to the moisture in straining the thick liquid is squeezed out, forms the filter cake on filter cloth 19 simultaneously.
After the return stroke is finished, the pulling plate system starts to work by controlling the hydraulic motor 16 on the hydraulic device, the pulling plate trolley 10 pulls the filter plates 18 one by one or more simultaneously, and meanwhile, the filter cakes fall off by the aid of the weight of the filter cakes in the filter cake groove 1. During the plate pulling process, the process can be suspended by controlling the valve. The motor drives the chain wheel 4 and the chain 8 mechanism, and then drives the pulling plate trolley 10 to control the stroke of the pulling plate, so as to ensure the smooth unloading. When the pulling plate work is completely finished, the pulling plate trolley 10 can return to one end of the oil cylinder 15 and stop.
The frame 3 part of the plate frame type filter press is the most main part of the whole machine and is the main body of the machine, and is used for supporting the filter mechanism and connecting other components. The hydraulic oil cylinder mainly comprises a thrust plate 6, a pressure plate 9, an oil cylinder 15, a main beam and the like. After the filter pressing process starts, the hydraulic pump supplies oil like the oil cylinder 15 to drive the piston in the oil cylinder 15 to push the pressing plate 9, and the pressing plate 9 presses the filter plate 18 and the filter cloth 19 through the pressure transmitted by the piston, so that the filter pulp can be pressurized and filtered when entering the filter chamber through the feed pump.
The embodiments described above are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
