Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Detailed technical scheme of the present invention:

[0017] The device of the present invention comprises a pressing filter part II and a pressing part I.

[0018] 1. The press filter component includes a built-in filter unit (the filter unit shown in the figure is a press filter disc 9, 12, 15 with a filter hole design and a press filter function) and a pressure-bearing cylinder 10. The filter unit and the pressure-bearing cylinder together constitute the cavity 14 for the squeezed material.

[0019] 2. The pressure-applying part consists of a built-in pressure-applying part (the pressure-applying part in the figure is a pressurizing piston 7) and a pressure-bearing cylinder 8. The pressure-applying part is combined with the pressure-bearing cylinder to form a pressure-applying liquid storage chamber.

[0020] 3. Open the feed valve 13 shown in th...

Abstract

The invention discloses a press filter device with a built-in core filter unit. The device includes a pressing and filtering component including a filter unit inside and a pressure applying component;the filter unit is placed in a pressed material to become the core of the pressed material. The pressed material is placed in a relatively sealed chamber, the squeezing pressure (up to 10 MPa) is improved, and the sealed press operation system avoids the loss of the pressed material during the pressing process, the pressing efficiency is improved, the pressing operation environment is improved, the space is made full use of, the occupation area is reduced by 50%, and for municipal sludge which is difficult to dehydrate, the dewatering rate can reach about 50%. For oil extraction and sugar production, the liquid yield can be increased by 0.5%.

Description

[0001] This application is a divisional application with the application date of 2018-06-08, the application number of 201810583639.5, and the name: "A squeeze filter device with a built-in kernel filter unit" technical field [0002] The invention belongs to the technical field of press filtration. Specifically relates to a press filter device with a built-in core filter unit. Background technique [0003] The traditional squeeze filtration is a process in which the liquid inside the squeezed material moves and flows out to the outer surface of the squeezed material under the action of extrusion to realize the squeeze filtration process. At present, there are belt filter press, plate and frame filter press and screw press filter press in the field of sludge drying. The sludge dehydration rate of these equipment is generally below 20%. After adding external solid auxiliary materials to the filter press system, the apparent dehydration rate of the plate and frame filter pre...
