Technical Field
[0001] The utility model relates to the technical field related to high-pressure oil cylinders, and in particular to a safety protection device for a high-pressure oil cylinder of a plate and frame filter press. Background Art
[0002] When the plate and frame filter press is working, the hydraulic oil given by the hydraulic station is input into the hydraulic cylinder, so that the cylinder reaches a certain pressure to press all the filter plates against the fixed tail plate end, so that a filter chamber is formed between the adjacent filter plates and the filter frame, and the slurry is fed in at high pressure from the feed port of the fixed tail plate, and the solid-liquid separation is completed with the help of the pressure of the fed slurry. When the filtrate no longer flows out, the dehydration process is completed, which is conducive to the orderly progress of subsequent blowing and pressing and other work. At present, the clamping cylinder of the plate and frame filter press is an ultra-high pressure auxiliary equipment. All the operations of the plate and frame filter press driver are basically carried out under ultra-high pressure. If the oil pipe interface breaks, it will injure people with serious consequences. There are also explosions at the bottom of the cylinder that will also injure people. This situation has many safety risks. Every year, injuries occur frequently due to inadequate cylinder protection. Utility Model Content
