Embodiment Construction
[0024] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0025] For the convenience of description, the assembly of several inner deflectors 3 and outer deflectors 4 on the discharge mandrel 2 is called a filter assembly.
[0026] A disc-type laminated filter, comprising a filter chamber cylinder 1, the filter chamber cylinder 1 is provided with a discharge mandrel 2, and a number of close-fitting and staggered sleeves are sleeved on the discharge mandrel 2 The inner deflector 3 and the outer deflector 4, the inner deflector 3 side is provided with grooves, the inner deflector 3 and the outer deflector 4 constitute a cavity for accommodating the filter screen 5, the cavity Circumferential sealing (that is, at the c...

A disc type laminated filter comprises a filter chamber tank, the filter chamber tank is internally provided with a discharge mandrel, the discharge mandrel is sleeved by a plurality of inner flow guide plates and outer flow guide plates which are closely attached and in staggered arrangement, opposite side surfaces of the inner flow guide plates and / or outer flow guide plates are provided with grooves, a cavity for accommodating a filter net is formed, the filter area is large, the space volume is minimized, and the product quality is improved; the outer diameter of the filter net and the cavity are sealed, the filter net is smoothly sandwiched between the inner and the outer guide plates, the sealing property of the filter net and the inner and the outer guide plates can be ensured while filteration, and filtered-impurities are adsorbed on the plane filter net, and are easy to clean; the inner diameter of the inner flow guide plates and the outer diameter of the outer flow guide plates are provided with a plurality of circumferential distribution diversion holes communicating with the cavity, and a material first can release most of the impact through the diversion holes of the outer flow guide plates, so that the filter net and the material can achieve a maximum filtration area, and the disc type laminated filter can perfectly run in a high pressure state.
Description
technical field [0001] The invention relates to a disc-type laminated filter, which belongs to the technical field of filtering equipment. Background technique [0002] At present, filter elements used in high temperature, high pressure, high viscosity materials (such as plastic industry) are generally formed by folding and extruding multi-layer wire mesh, then assembled on a skeleton of a porous tube, and then made through multiple processes. On the one hand, this structure can maximize the expansion area, prolong the filtration time at the same large volume, and have good pressure resistance. However, with the gradual development of the filter in the direction of full automation, the backwashing of the filter device has been paid more and more attention. However, the pleated structure of the filter screen of this device makes it difficult to clean after impurities enter, and the commonly used calcination method is easy to burn the filter screen, and the filter screen at t...
