Adopt the plate and frame type filter-press of technical solution of the present invention, comprise casing, casing plays a carrying, and introduced contaminants can be avoided to enter in food suspension, and casing top is provided with feed hopper and force pipe, feed hopper is used for the input of suspension, feed pipe is in closed state in the process of pressure filtration, and force pipe is used for pressurization, is provided with piston in force pipe, piston inwardly slides, thus can increase the gas pressure of casing internal, be provided with deflector in casing, deflector is provided with one group of groove, and deflector can play a guide effect to food suspension, and groove can pass through for food suspension, deflector lower end is positioned at each groove place and is equipped with one group of press filtration frame, press filtration frame also can play a guiding to food suspension, press filtration frame comprises the side plate of base plate and two pieces of square rings, the side plate of ring-type can make food suspension have trend to press filtration frame two lateral movement, the outside of two blocks of side plates is equipped with filter press plate, filter press plate and side plane contact, the first filter cloth is also provided with between filter press plate and side plate, filter press plate can support the first filter cloth, and filter press plate also can play water conservancy diversion to filtrate, first filter cloth is used for filtering food suspension, realize the Separation of Solid and Liquid of food suspension, also be provided with gripper shoe in casing, gripper shoe is for supporting press filtration frame and filter press plate, and gripper shoe is provided with multiple pod apertures, and pod apertures can be passed through for filtrate, casing bottom is provided with discharge nozzle, and filtrate can be derived by discharge nozzle.
Technique effect of the present invention is: piston moves inward, reduce the airtight space being positioned at ullage in casing, thus the gas pressure in described airtight space is increased, and then increase liquid phase and penetrate filter cake and through the power of filter cloth, make filter efficiency high; In addition, because each pressure frame both sides is equipped with vertical filter cloth, increases filter area, thus improve filter efficiency.
Further, described filter press plate both sides respectively with the side plane contact of two press filtration frames.Thus the quantity of filter press plate can be reduced.
Further, the both sides end face of described filter press plate is also provided with multiple downward groove.Downward groove can play a guiding to filtrate, filtrate is flowed downward easier.
Further, described gripper shoe is also provided with the second filter cloth.Second filter cloth can filter further to filtrate.
