Description
Technical field
The present invention relates to a kind of solid-liquid separating equipment, refer in particular to the compound tension-type filter press that suspension is filtered to be processed.
Background technology
At present, traditional pressure filter is the frame being made up of thrust plate, girder, compression or take-up device, is placed in the pressure strip on frame main beam, several piece filter plate and is layed in the filter element composition that the filter cloth on its surface is constituted.During pressure filter work, compress or first take-up device pushes or pull on pressure strip and be pressed between pressure strip and thrust plate by filter element, filter element is made to form the filter chamber of several good seal, then in the pipeline press-in filter chamber by supporting feed pump, suspension warp to be filtered being connected with thrust plate feeding mouth, liquid phase in suspension forms filtrate through filter cloth, filtrate channel on filter plate discharges filter element, solid phase in suspension is trapped in filter chamber by filter cloth and forms filter cake, so that the liquid phase in suspension separates with solid phase, complete the filtration treatment to suspension.When whole filter chambers are full of by filter cake, after suspension filtered operation terminates, compress or take-up device unclamps pressure strip, automatically one by one filter plate is pulled open either manually or by plate pulling device, filter cake comes off from unlimited filter chamber under gravity, and whole filter chamber dischargings terminate later cycle of operation and complete.
In pressure filter work process, due to the inherent shortcoming that tradition pressure filter its structural design aspect exists, cause that it exists following wretched insufficiency:
(1) sealing of filter element adopts compression mode, girder in frame should bear filter element own wt and the gravity of filter cake weight generation, bear the huge pulling force produced when compressing filter element again, girder very easily buckling deformation under combined stress effect；Meet rigidity and the requirement of strength of girder, improve whole aircraft reliability, the sectional dimension of girder certainly will be increased, directly result in the increase of complete machine weight and manufacturing cost.
(2) sealing of filter element adopts tension mode, although the girder in frame is not bearing combined stress, inherently improve the force-bearing situation of frame, but the lifting surface area of piston is little in tension hydraulic cylinder rod chamber, produce the thrust identical with compression mode, it is accomplished by increasing the cylinder diameter of hydraulic cylinder or improving the operation pressure of hydraulic system, the cylinder diameter increasing hydraulic cylinder causes the increase of complete machine weight and manufacturing cost, and the operation pressure improving hydraulic system not only increases manufacturing cost but also reduce whole aircraft reliability.
Summary of the invention
In order to overcome tradition pressure filter deficiency described in the background, the present invention provides a kind of compound tension-type filter press, this machine adopts tension and holds out against the mode combined and compress filter element, solves tradition compression type and the inherent shortcoming of tension-type filter press its structural design aspect existence well.
The technical solution adopted for the present invention to solve the technical problems is: this pressure filter is made up of frame, filter element, pressure strip, mobile holding device and take-up device.Frame therein includes thrust plate, two back timbers, two foundation beam and end supports, and back timber and bottom girder are respectively symmetrically the top and two bottom sides that are arranged on thrust plate and end support, and they are constituted the frame of a frame structure with bolt connecting mode；Being sequentially arranged filter element, pressure strip and mobile holding device in frame on two back timbers of thrust plate both sides, filter element, pressure strip and mobile holding device pass through its respective roller hanger suspending on two foundation beams；Mobile holding device includes holding out against support and holding out against hydraulic cylinder, holds out against hydraulic cylinder and is arranged on and holds out against on support, and its piston rod is connected with in the middle part of pressure strip；Take-up device includes two or four tension hydraulic cylinder, and tension hydraulic cylinder is symmetrically mounted on the both sides of thrust plate, their piston rod respectively with hold out against support two ends and be connected.Its operation principle is, first take-up device pulls mobile holding device and pressure strip by two tension hydraulic cylinders, close up and once compress filter element, move holding device while locking tension hydraulic cylinder and again hold out against pressure strip with bigger pressure by holding out against hydraulic cylinder, secondary compression filter element also starts filter operation, filtration is moved holding device after terminating and is first once unclamped pressure strip, then take-up device secondary unclamp pressure strip and move to appointment position start discharging, so far a cycle of operation terminates.
The invention has the beneficial effects as follows: compress filter element because have employed compound tension mode, inherit the advantage that tradition tension-type filter press girder is not subject to combined stress, overcome again because in tension hydraulic cylinder rod chamber, piston lifting surface area is little simultaneously, cylinder diameter or the shortcoming improving line pressure must be increased, while reducing complete machine manufacturing cost, whole aircraft reliability can be increased substantially.
